(the "Company") develops, manufactures, and markets immunoassay-based test kits and strip tests for rapid, cost effective detection of a wide variety of different analytes in three primary market segments: water quality, industrial testing and agricultural. The Company is the entity resulting from the combination of EnSys Environmental Products, Inc. ("EnSys"), Ohmicron Corporation ("Ohmicron") and Strategic Diagnostics, Inc. ("SDI"). On August 30, 1996, Ohmicron was merged with and into SDI. On December 30, 1996, SDI was merged with and into EnSys. The surviving entity was then renamed Strategic Diagnostics Inc. The Company is a recognized leader in the field of immunoassay research, development and manufacturing and develops products in markets where the attributes of immunoassay technology (i.e. speed, ease-of-use, cost effective, quantitation, and flexibility), meet specific customer needs. The substances detected by the Company's test kits and strip tests include chemicals used to treat drinking water, proprietary chemicals used in industrial processes, environmental contaminants, pesticides, genetically engineered traits in plants, and diseases of commercial crops. The Company's tests for the detection of pesticides and environmental contaminants (D TECH(R), EnviroGard(TM), EnSys RISc(TM) and RaPID Assay(R)) are well recognized in the immunoassay field testing market. The Company sells its environmental products through its direct sales force in the U.S. and through distributors in Europe and the rest of the world. The Company's "one-step" strip tests hold a leading position in the emerging markets of analytical tests for the detection of water-soluble polymers and specific traits of genetically engineered plants. In addition to products serving the three primary markets, the Company manufactures and sells select immunoassay test kits for medical research applications. In addition to developing and marketing test kits and strip tests, the Company provides fully integrated monoclonal antibody development and large scale manufacturing services to pharmaceutical and medical diagnostic companies through it's wholly-owned subsidiary, TSD BioServices, Inc. Immunoassay Technology An immunoassay is an analytical test that uses antibodies to detect the presence of a target compound in a complex sample matrix with high degrees of precision and accuracy. The technology was first developed more than 25 years ago and has replaced many laboratory diagnostic tests in the medical industry. The Company has applied immunoassay technology to a variety of industrial and agricultural applications. As with medical applications, immunoassay technology has demonstrated its value in these markets by virtue of its ability to yield specific, accurate, cost-effective and timely data in a manner previously unavailable. The major attributes of immunoassay technology can be summarized as follows: Sensitivity: Immunoassays can measure extremely low concentrations of compounds (routinely as low as parts per billion; i.e., one millionth of one gram in a liter of liquid). Specificity: Immunoassays can measure one specific compound out of a chemical "soup," reducing the need for sample preparation. Speed: Total time to obtain a test result ranges from 1 minute to several hours as compared to several days to several weeks with many competing laboratory testing methods. Cost: Price per test for immunoassays range from $1 to $50; price per test for similar laboratory testing can range from $5 to $1,000. Accuracy: Immunoassays are typically as or more accurate than their laboratory counterparts. Flexibility: Immunoassays can be developed in a wide variety of test formats, including multiple sample laboratory-based tests, disposable, single-use units, and large automated instruments. They can be designed for use by non-technical persons on-site under a variety of field conditions for testing of diverse sample types. 1 Immunoassay technology relies on the specific binding characteristics of antibodies. Antibodies are proteins made by cells within the bodies of animals as part of the immune response to invasion by foreign substances like bacteria and viruses. An antibody physically binds only to the substance that elicited its production. This characteristic of specific binding makes antibodies useful tools for detecting substances in complex sample matrices (e.g., blood, plant tissue, soil and water). Methods exist for isolating and purifying antibodies from animals, and labeling them in such a way that they can be used as components, or reagents, within a test to detect the presence of the substance of interest. Immunoassay technology has advanced to the point that antibodies can be made to a wide variety of substances including microorganisms, drugs, hormones, proteins, polymers, environmental pollutants and other chemicals. Once an antibody reagent that has the desired performance characteristics (sensitivity and specificity) has been identified, it can be incorporated into a test format that is appropriate for the customer's application. In the human clinical chemistry market, antibodies are employed as reagents on large, automated instruments that can analyze hundreds of samples per hour. In contrast, antibodies can also be packaged into single use, disposable formats such as the home pregnancy tests. Immunoassays can be designed to be highly quantitative or yield a simple yes/no result. The type of test format chosen for any given application depends on the needs of the customer and may include factors such as ease-of-use, cost per test, number of samples to be tested, the location the test will be performed and experience of the user. The Company has expertise and proprietary technology relating to the development and manufacture of primarily five immunoassay formats: latex filtration, magnetic particle, one-step strip tests, coated-tube and microtiter plate. Latex filtration assays offer ease-of-use, field portability and semi-quantitative results and are ideally suited for on-site, field screening applications where limited numbers of samples are to be analyzed. Magnetic particle assays have a greater number of steps and require more technical expertise to execute than latex filtration assays, but are more suited to the processing of larger number of samples at a single time, can be highly quantitative, and are relatively inexpensive on a cost-per-test basis. These characteristics make magnetic particle immunoassays effective measurement tools in both laboratory and certain field applications, especially where highly precise results are required. Lateral flow immunoassay strips, often referred to as 'one-step' strip tests, require only that the user apply a prepared sample to the test strip to obtain the test result--much like pH or Litmus paper tests. The low cost and simplicity of these tests make them ideally suited for a wide range of applications in many different markets. The current state-of-the-art of lateral flow immunoassays is such that the results obtained using these tests are qualitative, not quantitative, which imposes some limits on the applicability of the format. Coated-tube immunoassays are well suited for analyzing relatively large numbers of samples in the field, yield a semi-quantitative result and are intermediate in their ease-of-use and cost-per-test. Microtiter plate assays are well established in the medical diagnostic industry and offer many of the advantages of magnetic particle assays, including quantitative results and the capacity to analyze large numbers of samples at a relatively low cost-per-test. Special laboratory equipment, relatively high levels of technical training, and a time-to-result measured in hours limits this test format to laboratory applications. All measurement technologies, including immunoassays, have strengths and limitations. The Company's expertise with multiple immunoassay formats, coupled with a thorough understanding of the needs of a market and specific customer applications, has allowed the Company to develop a diverse array of immunoassay products designed to meet the analytical needs of multiple, sizable markets. 2 Markets and Products The Company sells products in the water quality, industrial testing and agricultural market categories through its direct sales force, through a network of over 40 distributors in Canada, Mexico, Latin America, Europe and Asia, and through its corporate partners. This section describes the Company's current markets and products as well as those in development. Water Quality The Company believes that all of its products sold in this market are unique to the Company and provide high value testing solutions to fill largely unserviced analytical needs in this critical and highly regulated industry. In this arena, the Company markets established products such as those for the detection of pesticides, as well as emerging products for the detection of pathogenic microorganisms and toxic chemicals resulting from chlorine disinfection of drinking water. Also included in this market category are products developed and others currently under development for the detection of water treatment polymers used to clarify water and prevent scale formation. Water Treatment Polymers. The water treatment market encompasses both industrial and municipal water treatment systems. Water treatment chemicals, typically polymers, are critical to preparing finished drinking water in municipal settings and to controlling water quality in industrial settings. Competition between water treatment chemical manufacturers is intense and new chemicals have evolved to the point that some of the more effective chemicals are quite expensive. Cost effective use of these chemicals requires careful control of polymer concentrations throughout the system in which they are being employed. Many of these polymers are toxic and have been implicated in fish kills when industrial effluents have been discharged to natural bodies of water. As a result, there is increased regulatory pressure to measure the amount of chemical being discharged into surface waters. Polymer detection is quite difficult and currently there is no other detection method capable of measuring these substances at the levels at which they are used or discharged in effluents. The Company, working in collaboration with its corporate partners, has successfully developed highly sensitive and accurate immunoassays for the detection of a number of water treatment polymers. These immunoassays have been demonstrated to be a reliable and cost-effective way to measure water treatment polymers in samples from municipal water supplies, boilers, cooling towers, and other processes and raw water sources. Some specific applications are: (i) measuring concentrations of chemicals to allow more efficacious use of costly compounds, (ii) detecting the presence of particular compounds in effluent discharge in order to gauge regulatory compliance, and (iii) monitoring processes to prevent fouling of highly expensive systems (like reverse osmosis) by excess polymer. Pesticides. The entrance of pesticides into the water supply as a result of agricultural and residential runoff continues to be a problem requiring analytical testing. In areas of substantial agricultural activity, drinking water is tested for several pesticides in order to ensure compliance with federal regulations. Imported grains, fruits and vegetables are tested for the presence of pesticide residues prior to use in the U.S. In addition, pesticide residues in crops call for extensive testing at the time of pesticide registration or re-registration under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). In spite of their banned status, pesticides such as DDT and chlordane still persist in soil at sites where they were stored or distributed. The clean up of these sites requires the use of specific analytical methods of pesticide detection. Cryptosporidium and Giardia. During 1994, the Company entered into an exclusive five-year license agreement, under which it would manufacture and sell Hydrofluor(TM), an EPA-accepted immunoassay-based method for detecting the pathogenic protozoa Cryptosporidium and Giardia in water. According to the EPA, Cryptosporidium and Giardia cause more outbreaks of disease than any other water born pathogens. The Company's Hydrofluor-Combo(TM) test kit has been designated as the American Society for Testing and Materials (ASTM) standard method for detection of these pathogenic protozoa and also has been designated as the method for use in complying with the EPA's Information Collection Rule to establish the extent of contamination in the nation's drinking water. Total Trihalomethanes. Trihalomethanes are regulated, toxic by-products that result from chlorine disinfection of drinking water. The Company's test is a non-immunoassay-based test for the detection of `total trihalomethanes' (TTHMs). The test is fast, easy and inexpensive, detects TTHMs at levels much lower than the new proposed safe drinking water guideline. The Company's TTHM kit has received US EPA Method Approval (Method 8530). 3 RaPID Assay(R) and EnviroGard(TM). The RaPID Assay(R) and EnviroGard(TM) pesticide test kits are being used extensively by water quality researchers, resource managers, regulators and drinking water system operators for surface and groundwater monitoring, drinking water source and supply management, and chemical fate and transport studies. Users of the Company's water quality pesticide products include federal agencies, such as the U.S. Geological Survey and Department of Agriculture, state environmental and health departments, drinking water utilities, and environmental engineering companies. Industrial Testing The industrial testing market category is comprised of immunoassays for pollutants, proprietary chemicals and industrial markers. Pollutants. Analysis of soil, water and waste samples to determine the presence of hazardous chemicals has become increasingly important in connection with environmental remediation and environmental monitoring activities. These activities are largely the result of environmental legislation such as RCRA, CERCLA, TSCA, the Safe Drinking Water Act (SDWA) and Federal Water Pollution Control Act (the "Clean Water Act"). The Company believes that approximately 1,200 commercial environmental testing laboratories, as well as "in-house" laboratories at industrial and disposal facilities provide environmental testing. Environmental remediation activities require a substantial amount of testing in connection with the clean up of contaminated sites. After initial characterization of toxic chemicals at a site, substantial testing typically is required to complete an assessment of the site to determine the extent and location of contamination and the appropriate remediation plan. Upon the commencement of the remediation project, additional testing is necessary to determine the effectiveness of the remediation measures. In addition, ongoing testing to monitor soil and groundwater is often required after completion of the remediation activities. The contaminants of primary concern for remediation activities include petroleum fuel products, polyaromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), benzene, certain metals and chlorinated solvents. Environmental monitoring activities under SDWA and National Pollution Discharge Elimination System (NPDES) legislation require periodic testing for various hazardous chemicals. The nation's 58,000 drinking water systems test for contaminants such as metals, benzene, other volatile organic compounds and microbiological contamination. Approximately 6,400 major industrial and municipal wastewater treatment facilities monitor and test wastewater for contaminants such as chlorinated solvents, metals and volatile organic compounds. Hazardous waste handling and disposal companies carry out large volumes of analytical work, including pre-acceptance testing to determine the suitability of waste streams for disposal and routine testing of incoming shipments. In addition, the ongoing management of chemicals in the petrochemical and pesticide industries also results in the need to test samples at many points in the production, use and disposal cycle. Electrical utilities have on-going analytical needs pertaining to disposal of PCB containing materials. Proprietary Chemicals. The proprietary chemical market category includes tests, commissioned by chemical manufacturers, that specifically measure the particular compound of interest. In the chemical market category the benefits of immunoassay testing have led to three key applications: (i) regulatory registration, in which immunoassay data is generated to support the registration of a product with the EPA; (ii) detection, to determine whether a target compound is present in a complex matrix; and (iii) monitoring, in which tests are performed to determine chemical concentrations for control purposes. The application of immunoassay technology in conjunction with regulatory registration is significant because of the requirement that large-scale chemical manufacturers register their chemicals under FIFRA with the EPA. As part of this registration process, manufacturers must provide extensive data for both registration and post-registration analyses regarding toxicity and environmental impact. For many new compounds, certain aspects of this analysis require sensitivity which instrument-based testing cannot achieve. For others, no classical analytical methods are available to measure the compound. In either case, EPA requires the manufacturer to supply a method to monitor the compound in the environment. The Company is currently commercializing four tests in this area for two chemical companies. Agreements are in place for the development of seven additional tests. 4 Industrial Markers. The Company is collaborating with a corporate partner in this market category, which consists of test kits that detect marked products. The product marking technology is based on the incorporation of trace levels of inert chemicals or markers into solid or liquid products or on the surface of the products. The use of these markers, in conjunction with immunoassay techniques for marker detection, allows for the covert marking and testing of nearly any product. This technology can be used to prevent revenue loss due to counterfeiting and product diversion, limit a manufacturer's exposure to unwarranted product liability, and enhance process efficiency and product quality assurance. Pollutant Test Products. The Company sells four different format immunoassays into the environmental market: (i) D TECH(R) latex filtration tests, (ii) EnSys RISC(TM) and EnviroGard(TM) coated-tube tests, (iii) RaPID Assay(R) magnetic particle tests and (iv) EnviroGard(TM) microtiter plate tests. Each of the four different test formats has performance characteristics that make them more or less suited for a particular customer application. The Company positions the sale of all of its products so as to provide the customer with the best product for its specific application. The D TECH(R) and EnSys RISC(TM) tests do not require refrigeration which make them ideally suited for on-site, field applications. All of the environmental test kits include components for the extraction of target analytes from the sample and subsequent analysis. Sample preparation time is typically less than five minutes per sample. All of the Company's environmental test kits are capable of analyzing at least ten samples per hour and some allow analysis of as many as forty samples per hour. D TECH(R). The D TECH(R) tests are a latex filtration immunoassay format and provide for rapid, easy to use, on-site, field screening analysis of soil and water samples containing EPA Priority Pollutants like PCBs, PAHs (polyaromatic hydrocarbons), TNT, BTEX (benzene, toluene, ethylbenzene and xylene) and others. D TECH is very simple to use, requires little or no user training, yields a semi-quantitative result and is ideally suited for true field applications where limited numbers of samples are to be analyzed at one time. RaPID Assay(R). The RaPID Assay(R) magnetic particle immunoassay product line currently contains kits and accessories for detection of 21 different pesticides (herbicides, insecticides and fungicides), and 6 toxic organic compounds. The magnetic particle test format is ideally suited for applications requiring highly precise determination of contaminant concentrations. Like the Company's other immunoassay tests, RaPID Assay(R) is fast and easy to perform, but not as field-portable. RaPID Assay(R) pesticide test kits are used for quantitation of pesticides in water, soil and food. RaPID Assay(R) test kits for toxic organic chemicals are used for measuring contaminant concentrations in both water and soil. EnviroGard(TM) and EnSys RISC(TM). Like D TECH(R) and RaPID Assay(R), these coated-tube and microtiter plate format testing products detect some of the most commonly encountered toxic chemicals found in soil, water and on surfaces at contaminated sites, including PCBs, fuel products, PCP, TNT, benzene, PAHs, crude oil, and pesticides. Additionally, the EnviroGard(TM) products detect pesticides in drinking water and foodstuffs. The coated-tube format tests are used extensively to analyze relatively large numbers of samples in the field and yield a semi-quantitative result. The EnviroGard(TM) microtiter plate kits are designed for use in the laboratory and are ideally suited for analysis of large numbers of samples where determination of exact concentrations of contaminants are required. Agricultural The agricultural market segment includes tests to detect targeted traits in genetically engineered plants, two plant fungi, Rice Blast and Botrytis (crop testing), and tests to detect Genetically Modified Organisms (GMOs) in food and food fractions (food testing). Crop Testing Genetically Engineered Crops. Agricultural companies are developing varieties of commercially important crops like corn, cotton and soybeans that have new additional genes which confer some commercial advantage to the plant, such as insect or pesticide resistance or enhanced growth or nutritional characteristics. Industry experts predict that roughly one quarter of the acreage used to grow corn in the U.S. will be planted with genetically engineered seed by the year 2000, in comparison to only 0.5% in 1996. 5 A large agricultural chemical company that has developed proprietary varieties of insect-resistant corn and cotton using genetic engineering technology commissioned the Company's first test in this market. Not all the seed produced by a genetically engineered plant contains the gene for the desired trait and therefore not all the plants arising from a batch of seed will express the desired characteristic. The Company has developed a simple `one-step' strip test that is used at the point of testing to determine if an individual plant contains the new genetic trait. The Company has also developed similar one-step products for other crops. Commercial seed producers use these products to ensure the quality of their products. This type of test can also be used for enforcement purposes in crops to prevent unlicensed application of the genetic technology. Sales of this strip test and similar products to detect the presence of genetically engineered traits in plants have been increasing rapidly since their introduction in the third quarter of 1995 and the Company believes sales will continue to grow. The number of acres of crops with genetically enhanced traits under cultivation grew rapidly in 1998 and published reports indicate that the farmers' experience with these products was positive. Acreage in 1999 is expected to grow further based on these results and with this increased volume, the Company expects sales of these products to grow. Additional tests for genetically engineered plants are currently under development. Food Testing In 1998, a significant market opportunity for immunodiagnostic analysis was created. This opportunity arose from regulatory response to public demands to address a consumer's right-to-know whether a food product contains concentrations of Genetically Modified Organisms (GMOs). In May 1998, the European Commission enacted food regulations governing the labeling of foodstuffs that are derived from genetically-modified crops. The legislation affects food processors in all fifteen member states within the European Union. Under the European Commission's EC 258/97 and EC 1139/98, beginning March 1, 1999, food processors are required to label food ingredients for the presence of GMOs. During the second half of 1998, the Company entered into licenses to use proprietary genetic traits with major developers of genetically-engineered plants, and began developing an immunodiagnostic test to detect the presence of GMO's at specified concentrations. This research and development was completed and the Company participated in a Joint Research Centre - Institute for Health and Consumer Protection Food Products Unit sponsored validation study of its first test kit. Validation studies are common in the food testing industry and are generally referred to as "Ring Studies." This Ring Study involved 38 qualified laboratories throughout Europe and was completed in December 1998. The JRC has informed the Company that its products have been validated to detect the presence of the tested traits at the thresholds established in the Ring Study protocol. Also during the second half of 1998, the Company began to introduce its technology and product plans to food processors. The reaction from the marketplace was and continues to be positive. Prospective customers have shown interest in the ability of the Company's technology and products to detect the presence of GMOs above a specified threshold level, its fast time-to-result and cost advantages. First shipments of this initial test kit occurred in the first quarter of 1999. The Company expects this newly created market opportunity to expand rapidly throughout 1999. The Company's initial products, as well as others planned for 1999, provide food companies an alternative to the more expensive and time-consuming DNA methods. The Company has developed a customer council consisting of three of the world's largest food companies to assist in the final design and validation of the test formats. Food companies have indicated that they believe the simplicity of the Company's test kit compares favorably against DNA methods that usually require more significant laboratory analysis and a longer time-to-result. The Company's test kit will allow food processors to conduct the testing at each manufacturing site. This will not only reduce costs, but will also allow for easier integration into the daily operations of manufacturing facilities. The Company estimates the market potential for food test kits could reach $20 million by the end of the year 2001. This estimate is based on the volume of food fractions used by the more than 22,000 European food processors. The Company believes this newly created market opportunity could expand even further. Legislation similar to the European legislation was passed in Australia and New Zealand in December 1998. Japan and Canada are considering similar legislation as well. The two largest crops that are currently being genetically modified are soya and maize, but others such as rice and wheat will add to the growth. Projected production of rice for 1999 is 376.6 million tons of the milled variety, and world consumption is projected at 385 million tons. 6 Other Products Macra(R) Lp(a). Macra(R) Lp(a) is a microtiter plate assay that measures a lipoprotein found in human serum. This lipoprotein has been shown to be an indicator of risk for myocardial infarction, heart disease and stroke. A great deal of clinical data has been generated with the Macra Lp(a) kit because of its leading research position, and its use in benchmark projects such as the Framingham Study, a multi-generation analysis of coronary risk factors. The product received FDA 510(k) approval during 1998, and the rights to this product were subsequently sold in July 1998 (see Note 19 in Notes to the Consolidated Financial Statements). RapidChek(R) SRB. Sulfate Reducing Bacteria ("SRBs") are environmentally significant because they generate hydrogen sulfide gas and cause corrosion of stainless steel pumps, pipelines, and drilling rigs and result in the souring of oil reserves. SRBs can be controlled by the addition of treatment chemicals. Historically, the majority of testing in this market was performed using a culture method called the American Petroleum Institute Recommended Procedure No. 38. This method requires that samples be incubated from 14-28 days before a result is obtained. RapidChek(R) SRB test is a simple to use, field portable test that provides the user with accurate results in 20 minutes and allows for an immediate, more cost effective application of treatment chemicals. Major Customers In 1998, Delta and Pine Land Company accounted for 10% of the Company's revenues. Delta & Pine Land Company and Rohm and Haas Corp. each accounted for 10% of the Company's 1997 revenues. In 1996, EM Industries and Ensys (see Note 3 in Notes to the Consolidated Financial Statements) accounted for 11% and 19% of the Company's revenue, respectively. Sales and Marketing Strategy As a result of the consolidation of SDI, EnSys, Ohmicron and EnviroGard(TM) businesses, the Company has formed an experienced sales and marketing organization of 25 individuals. In addition to its direct sales force, the Company sells product through an extensive network of distributors, and through its corporate partners. The Company uses a number of strategies for the sale of its products worldwide. In the U.S., the major route of sale of its industrial testing products is through a national field sales force in defined sales territories. The field sales force is augmented by an in-house sales force, which in addition to selling product directly to customers, provide marketing and logistic support to the field sales personnel and interface between customers and technical support. In 1993 the Company opened a European headquarters and sales operation near London, England, and the sale of the EnSys RISC(TM), RaPID Assay(R) and EnviroGard(TM) products in Europe are principally directed through that office. Sales and distribution of the D TECH product line outside of the U.S. are made exclusively by E. Merck KGaA, Darmstadt, Germany. Sales of the Company's products for detecting water treatment polymers, proprietary chemicals, industrial markers, genetically engineered crops and Rice Blast are through the Company's corporate partners in selected markets and through the Company's direct organization in others. The RapidChek(R) SRB test kit is sold directly by the Company and through 5 international distributors. Regulatory Approvals The environmental legislation and regulations that the Company believes are most applicable to its current business are RCRA, CERCLA, TSCA, FIFRA and the Pure Food and Drug Act. As the Company expands its product line to meet the environmental monitoring needs of municipalities and industrial facilities, the SDWA, the Clean Water Act and the NPDES permitting program under the Clean Water Act also will be significant to the Company's business. These laws regulate the management, disposal and clean up of hazardous substances and protect the nation's ground and surface water and drinking water supplies. In addition, regulatory responsibilities in a number of areas have been delegated to state agencies and state and local laws and regulations impose additional restrictions and requirements. While environmental regulations overseas vary, many countries, particularly in Europe, have counterparts to the U.S. legislation. 7 The Company believes that regulatory acceptance, though not required for the use of its products in most cases, is a significant factor in gaining market acceptance. There are two main areas in which the Company is seeking regulatory acceptance for its products: hazardous waste testing methods by the federal and state environmental protection agencies and water testing methods by the federal and state environmental protection agencies. The federal Environmental Protection Agency and some state agencies have evaluated certain of the Company's analytical methods and accepted their use for certain remediation and monitoring activities. Further acceptance by these agencies would further stimulate demand for the Company's products. The Company expects that as its products are subjected to wider use under a variety of conditions and subjected to traditional validation techniques, such acceptance will generally be granted. Such acceptance would serve to strengthen already compelling customer motivations such as the ease-of-use and specificity characteristics of the Company's products and is not a prerequisite to selling the products in the markets the Company serves. Hazardous Waste Testing Methods. EPA SW-846 is the compendium of analytical and test methods published by the EPA's Office of Solid Waste (OSW). A number of provisions of the EPA's hazardous waste regulations under RCRA mandate the use of SW-846 methods. In other contexts, SW-846 is a guidance document setting forth acceptable, although not required methods to be implemented by the user in response to sampling and analysis requirements. Some states also require the use of SW-846 methods under their hazardous waste programs. While SW-846 methods are technically only applicable to regulatory programs under RCRA, other federal, state and local environmental programs, including CERCLA and TSCA, often refer to and rely on SW-846 methods for purposes of remediation and monitoring. The process for a method to be incorporated into EPA SW-846 generally takes approximately 24 to 36 months. The OSW evaluates the applicant's test results and obtains additional information or conducts its own tests if necessary. After a method is deemed acceptable, it is published by the EPA in draft form ("EPA Draft Method"). Periodically, the EPA updates SW-846 through a notice in the Federal Register referencing the EPA Draft Methods published since the last update. Following a comment period, the EPA Draft Methods are referenced in the Federal Register as a Final Rule and incorporated into SW-846. The following table summarizes the EPA acceptance status of the Company's products. - ------------------------------------------------------------------------------------------------ EPA SW-846 Method D TECH(R) EnSys RISC(TM) EnviroGard(TM) RaPID Assay(R) No. Analyte - ------------------------------------------------------------------------------------------------ 4010 PCP Soil & Water Soil - ------------------------------------------------------------------------------------------------ 4015 2,4-D Soil & Water Soil & Water - ------------------------------------------------------------------------------------------------ 4020 PCB Soil Soil & Oil Soil Soil - ------------------------------------------------------------------------------------------------ 4030 TPH Soil Soil 4035 PAH Soil (APAH) Soil (APAH) Soil (APAH) Soil (CPAH) - ------------------------------------------------------------------------------------------------ 4040 Toxaphene Soil 4041 Chlordane Soil 4042 DDT Soil - ------------------------------------------------------------------------------------------------ 4050 TNT Soil & Water Soil & Water 4051 RDX Soil & Water - ------------------------------------------------------------------------------------------------ 4670 Triazines Water - ------------------------------------------------------------------------------------------------ 8510 RDX Soil 8515 TNT Soil 8530 TTHM Water - ------------------------------------------------------------------------------------------------ Water Testing Methods. Water testing methods approved for use in compliance with the SDWA are published periodically in the Federal Register. Newly developed methods are reviewed by the EPA's Environmental Monitoring and Systems Laboratory in Cincinnati to determine whether they are (i) an acceptable version of a previously approved method or (ii) a new method in need of a comparability study and proceed through a comment and approval procedure. The EPA has a program aimed at expediting the approval of new methods that involves the cooperation of the Solid Waste, Drinking Water, and Waste Water methods groups. 8 The TTHM (total trihalomethanes) water test has been accepted as Method 8530. In addition, the RaPID Assay(R) Atrazine test was accepted as the first quantitative immunoassay method. It is anticipated that the EPA Office of Drinking Water will adopt this method for screening according to the Drinking Water Regulations for Triazines under the SDWA. More recently, the Company's RaPID Assay(R) for Spinosad has been adopted by the EPA office of Pesticide Programs as the official enforcement method for this pesticide. The Hydrofluor-Combo(TM) test kit is the ASTM standard method for detection of these pathogenic protozoa and has been designated as the method for use in complying with the EPA's Information Collection Rule to establish the extent of contamination in the nation's drinking water. Tests for water treatment polymers, genetically engineered traits in plants, and fungal plant pathogens are currently unregulated. However, agencies such as the EPA, the FDA and the Food Safety and Inspection Service of the U.S. Department of Agriculture are engaged in testing environmental samples and, together with the Association of Official Analytical Chemists ("AOAC"), maintain compilations of official methods for use in testing for environmental contaminants in certain market segments. Some of these organizations also issue procedures and guidelines for validating new methods. Manufacturing The Company currently manufactures over 150 different test kits for the detection of a wide array of analytes in five immunoassay formats; one-step strip tests, coated-tubes, latex particles, magnetic particles and microtiter plates. In addition to test kits, the Company supplies its customers with ancillary equipment and supplies including spectrophotometers, pipettes, balances and timers among others. The kit manufacturing process consists mainly of critical reagent production and in process testing, filling and dispensing, labeling, kit assembly, quality control, packaging and shipping. The Company's Technical Reagents Manufacturing group produces critical reagents from its laboratories in Newark, DE. Sub-assemblies and finished kits are manufactured and shipped worldwide out of the Company's headquarters facility in Newark, DE. Biological materials are primarily developed and produced in-house, however, some reagents are licensed from third parties or purchased from commercial sources. A crucial step in the Company's manufacturing process is the stabilization of the immunoreagents utilizing proprietary lyophilization techniques. In general, raw materials used by the Company in its products are obtainable from multiple sources. The Company purchases instruments and ancillary equipment from outside vendors. A number of the instruments sold by the Company were developed to be used exclusively with the Company products and are subject to specific supply agreements. The Company believes that the raw materials, instruments and equipment used in the manufacture of its products are adequately available for the Company's current and foreseeable manufacturing needs. The Company manufactures its products in accordance with the FDA's Good Manufacturing Practices guidelines and has put in place systems designed to control all elements of the manufacturing process including raw materials, inventory, processes, documents, work-in-process, lot records, equipment and training. Integrated inventory control, purchasing, manufacturing scheduling, order processing, shipping and customer invoicing are elements of the Company's computerized Manufacturing Resource Planning (MRP) systems. The Company's manufacturing organization, including the Technical Reagents Manufacturing group, consists of 39 individuals. The Company believes the existing facilities and equipment are sufficient to support a significantly larger manufacturing base. Manufacturing operations are currently running a single shift. 9 Research and Development The Company engages in substantial research and development activities involving antibody and immunoassay development. In the three years ended December 31, 1998, 1997 and 1996, the Company incurred approximately $1,922,000, $1,580,000 and $1,569,000, respectively in research and development expenditures, substantially all of which are pursuant to customer research agreements or Corporate Partnerships. The Company's laboratory facilities located in Newark, DE were designed and built specifically for conducting research and development relating to antibody and immunoassay technology. These facilities include the state-of-the art, GMP, American Association for Accreditation of Laboratory Animal Care ("AAALAC") approved, TSD BioServices monoclonal antibody development and large-scale production facility. The Company has assembled a scientific staff with extensive experience in the development of monoclonal and polyclonal antibodies, immunogens and assay reagents. The Company's assay development scientists are experienced in developing tests in a variety of different immunoassay formats including one-step strips, latex filtration, magnetic particles, coated tubes and microtiter plates. Research and development personnel have complementary skills in several advanced research disciplines, including synthetic organic chemistry, protein chemistry, biochemistry, immunology, immunochemistry, microbiology and soil science. In addition to the technical expertise resident within research and development, TSD BioServices provides the Company scientists, as well as its outside clients, with large-scale GMP production, bioprocessing, purification and quality control of antibodies and reagents. The Company's research and development activities are focused on developing products to expand its manufacturing base and leverage its Sales and Marketing organization. The Company is a recognized leader in the field of contract antibody and immunoassay research and development in the industrial, water quality and agricultural sectors, and markets its services primarily to large chemical and pharmaceutical companies. Product development is typically performed in collaboration with a corporate partner that has identified a specific market need and provides funds to the Company to develop an assay. Research and development contracts are typically structured such that technology developed within the program are co-owned by the Company and its partner and the Company maintains exclusive manufacturing rights. To the extent the Company believes that improvements to existing products significantly enhance competitiveness, expand a market or improve market penetration, the Company has periodically funded such efforts. In the markets where the Company has chosen to compete, rapid field screening tests are highly valued and the Company is actively engaged in developing proprietary technology to better meet those needs and enhance the Company's overall performance. Through its continuing development of tests to detect genetically engineered plants and water treatment polymers, the Company has gained extensive expertise in development and manufacture of one-step strip tests, and is working aggressively to further develop this technology. The Company's technology organization, including research and development, TSD, Technical Reagents Manufacturing, and Technical Marketing Support consists of approximately 48 individuals of which 15 hold advanced academic degrees. Proprietary Technology and Patents The Company's products are based on the use of proprietary reagents, technology and test systems developed by Company scientists or acquired externally. Accordingly, the Company has implemented a number of procedures to safeguard the proprietary nature of its technology. The Company requires its employees and consultants to execute confidentiality agreements upon the commencement of an employment or consulting relationship with the Company and all employees are required to agree to assign to the Company all rights to any inventions made during their employment or relating to the Company's activities. Additionally, the Company seeks to protect its technology and processes through the patent process. The Company currently holds seventeen issued U.S. patents and the claims for another is in a state of allowance. Two U.S. patents have been licensed for exclusive use by the Company and six U.S. patent applications are pending. During 1998, the Company reached an agreement with FMC Corporation, which resulted in FMC assigning certain patent applications to the Company, in return for development of test kits for the detection of FMC water treatment polymers. The assignment of the FMC applications effectively resolved the interference proceeding, pending against the Company, related to U.S. Patent 5,593,850, also relating to immunoassays for the detection of water treatment polymers. 10 An alternative method of detecting water treatment polymers is to chemically couple an unrelated "marker" substance to the polymers and use antibodies and immunoassays that bind to the marker to detect the polymer. The technology for using anitbodies to detect markers that are chemically coupled to a substance to be detected is patented by Biocode Incorporated (U.S. Patent 5,429,952). In 1996 the Company licensed from Biocode Incorporated the exclusive rights to this technology for the detection of water treatment polymers. The Company believes that together, the `850 patent, FMC applications and the Biocode license provide broad protection for the use of immunoassay detection of water treatment polymers. - ----------------------------------------------------------------------------------------------------------- U.S. Patent Title - ---------------------- ------------------------------------------------------------------------------------- 4,999,286 Sulfate reducing bacteria determination and control 5,200,346 Aldicarb immunoassay by sulfone equivalents 5,411,869 Immunological analogs for captan 5,449,611 Polyaromatic hydrocarbon (PAH) immunoassay method, its components and a kit for use in performing the same 5,484,709 Immunoassay method for detecting an immunologically non-remarkable compound 5,547,877 Methods for the rapid detection of toxic halogenated hydrocarbons and kits useful in performing the same 5,554,730 Fungus extraction method and kit 5,576,187 Standards for phosphorothioate insecticide immunoassays 5,593,850 Monitoring of industrial water quality using monoclonal antibodies to polymers 5,618,681 Polyaromatic hydrocarbon (PAH) immunoassay method, its components and a kit for use in performing the same 5,658,463 Kits and processes for extraction of analytes from solid materials 5,679,574 Quantitative test for oils, crude oil, hydrocarbon, or other contaminants in soil and a kit for performing the same 5,691,148 A petroleum immunoassay method, its components and a kit for performing the same Allowed Immunoassay standards for volatile analytes with benzene rings 5,780,250 Immunoassay standards for polyaromatic hydrocarbon detection 5,834,222 Polychlorinated Biphenyls (PCB) immunoassay method 5,858,692 PCB immunoassay 5,874,216 Indirect label assay device for detecting small molecules and method of use thereof 5,541,079 Monoclonal and polyclonal antibodies and test method for determination of organophosphates (license) 5,429,952 Marking of products to establish identity and source (license) The Company believes that low-cost, easy to use, rapid field screening tests have the potential to be significant products in its chosen markets. Therefore, the Company is aggressively developing technology relating to immunoassay formats with those features. Two of the Company's pending applications involve one-step strip test formats, and one of the applications has to do with a novel latex filtration test format. In addition to the assay format patent applications, the Company has pending applications relating to immunoassays for trichloroethylene (TCE) and water treatment polymers. There can be no assurance that the Company's patent applications will result in the issuance of any patent or that any patents issued to the Company would provide protection that is sufficiently broad to protect the Company's technology and products. In addition, the Company cannot be certain that it was the first creator of inventions covered by pending patent applications or that it was the first to file patent applications for such inventions. In addition to seeking patent protection for the Company's proprietary information, the Company also relies upon trade secrets, know-how and continuing technical innovation to maintain competitiveness. The Company has developed a number of proprietary technologies which the Company has chosen not to patent including stabilization systems for reagents, chemical syntheses for conjugates, immunogens and analyte analogs, and strategies relating to antibody development. Regarding the latter, the Company's extensive expertise has enabled it to develop antibodies and products that are unique to the industry including monoclonal antibodies to transgenic plant proteins, water treatment polymers, the explosive RDX, BTEX and TCE. 11 Under two license agreements, the Company has been granted the right and license throughout the world to use magnetocluster technology in connection with the Company's RaPID Assay(R) products for the detection of environmental analytes. This license carries royalties starting at 4% of net sales of such products each year and declining to 2% based upon the volume of sales in such year. Competition Many of the Company's potential competitors are large companies with substantially greater financial and other resources than the Company. To the extent that any such companies enter into one or more of the Company's markets, the Company's operations could be materially, adversely affected. The Company anticipates increased competition as potential competitors perceive that the Company's markets have become commercially proven. Other companies may be developing additional products for one or more of the Company's markets that could be competitive with the Company's products. Nevertheless, the Company believes that its competitiveness has been significantly enhanced as a result of the consolidation of the SDI, EnSys, Ohmicron and EnviroGard(TM) businesses. Currently, the Company believes that there are no similar competing immunoassay products for the Company's RapidChek(R) Rice Blast, Botrytis and SRB, GeneCheck(TM) B.t.k., proprietary chemical, industrial marker or water treatment polymer tests. The Company holds U.S. patents relating to the Rice Blast and SRB tests and believes they will help to provide a competitive advantage in the event that competing products enter the market. The Company's water treatment polymer tests are unique to the industry and the Company has secured U.S. patents and an exclusive technology license and believes that such property will help to provide a competitive advantage in the event that competing products enter the market. A number of companies already have pursued, and are actively pursuing, products for the detection of Cryptosporidium and Giardia in drinking water and it is likely that the Company's Hydrofluor products will face increasing competition in the future. Hydrofluor currently benefits from its designation as the ASTM standard method for detection of these protozoa and from its selection by the EPA as the method for use in complying to the EPA's Information Collection Rule to establish the extent of contamination in the nation's drinking water. The Company's Macra(R) Lp(a) product competes with other existing immunoassay tests in the marketplace, but since it was first to the market, Macra(R)'s competitive position is enhanced by the large quantity of clinical data that has been generated by researchers and clinicians that have used the test in large prospective studies (see Note 19 in Notes to the Consolidated Financial Statements). Employees As of December 31, 1998, the Company employed 107 full time and 2 part time individuals including 96 regular and 13 contract employees. All of the Company's employees have executed agreements with the Company agreeing not to disclose the Company's proprietary information, assigning to the Company all rights to inventions made during their employment, and prohibiting them from competing with the Company. None of the Company's employees are covered by collective bargaining agreements. The Company believes that its relations with its employees are good. ITEM 2. PROPERTIES The Company is headquartered in Newark, DE, and occupies approximately 28,000 square feet of space under an operating lease expiring in December 2007. The Company also leases approximately 26,000 square feet of manufacturing and research space also in Newark, DE under three operating leases that expire in October 2000, October 2001 and November 2003, respectively. 12 TSD BioServices Inc. occupies approximately 8,000 square feet of manufacturing, research and animal facility space, in Newark, DE. Prior to the merger with the Company, EnSys leased approximately 18,000 square feet of space in one building in the Research Triangle park area in North Carolina under a ten-year lease that expires in 1999 with a renewal option through 2004. Following the merger, the Company closed the North Carolina operation and has sub-let the space to an unrelated third party for the remaining term of the lease. The Company leases regional sales offices near London, England, Newport Beach, CA, and Chestnut Hill, MA. The Company also leases warehouse space of 1,600 square feet or less with leases that run one year or less. The Company believes that its equipment and facilities are adequate for its present purposes. ITEM 3. LEGAL PROCEEDINGS The Company is not a party to any material legal proceedings. ITEM 4.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION Forward Looking Statements This Form 10-K contains several forward-looking statements reflecting the Company's current expectations. When used in this Annual Report, the words "anticipate", "estimate", "enable", "believe", "expect" and similar expressions as they relate to the Company are intended to identify said forward-looking statements. Investors are cautioned that all forward-looking statements involve risks and uncertainties, which may cause actual results to differ from those anticipated at this time. Such risks and uncertainties include, without limitation, the Company's ability to manage growth, the integration of acquired companies, including HTI Bio-Products, Inc., unknown Year 2000 issues, changes related to acquisitions such as the amortization of significant goodwill and other intangible assets, changes in demand for products, delays in product development, inability to obtain required government approvals, modifications to existing government regulations, modifications to development and sales relationships, the ability to achieve anticipated growth, seasonality, competition and other factors more fully described in the Company's public filings with the U.S. Securities and Exchange Commission. Overview The Company is the entity resulting from the combination of EnSys, Ohmicron and SDI. On August 30, 1996, Ohmicron was merged with and into SDI, with certain Ohmicron stockholders and note holders receiving shares of SDI common stock. On December 30, 1996, SDI was merged with and into EnSys. The surviving entity was then renamed Strategic Diagnostics Inc. Each of these transactions was accounted for as a purchase with SDI as the acquiring company and, therefore, the surviving company for financial reporting purposes. As a result, the historical financial information discussed includes the results of SDI for all periods presented and the actual results of Ohmicron from August 30, 1996 and EnSys from December 30, 1996. 17 EnSys was formed in 1987 to develop proprietary biotechnology based test systems designed for fast and inexpensive detection of various chemicals in soil and water samples. EnSys raised approximately $30 million in equity financing, including approximately $16 million from the sale of 1,800,000 shares of EnSys common stock in its initial public offering in October 1993. Since 1991, EnSys commercialized eleven immunoassay test kits and four other test kits for the detection of various environmental contaminants. EnSys marketed and sold these test kits and other associated products and services to environmental consulting and engineering firms, hazardous waste processing firms, environmental testing laboratories, and various state and federal agencies through distributors and a regionally based direct sales force in the U.S. EnSys also marketed and sold its products in Europe through EnSys (Europe) Limited, a wholly owned subsidiary of EnSys. In March 1996, EnSys acquired from Millipore, Inc. certain assets, which consisted primarily of inventory, work-in-process, equipment, intellectual property rights, contract rights and customer lists related to Millipore's EnviroGard(TM) product line for $1 million and 1,100,000 shares of EnSys common stock. Ohmicron was founded in 1984 and began marketing its RaPID Assay(R) products in 1991 to the same general market and in the same fashion as previously described for EnSys. Since its inception, SDI has focused on using proprietary technology and know-how to develop, manufacture and market immunoassay test kits for applications primarily in the water quality, industrial testing and agricultural markets. One of the strategies SDI used to develop its business was to establish relationships with other companies that had significantly greater resources and capabilities to evaluate market opportunities and potential for new products. The Company refers to these relationships as "Corporate Partnerships". Corporate Partners, who had identified and researched a market opportunity, funded SDI to develop and manufacture immunoassay products to meet the market need. Most of the Corporate Partner agreements were written so that SDI retained a right to manufacture the finished product, and any technology developed during the course of the project was co-owned by SDI and its partner. In this way, SDI developed proprietary technology and built a base of manufactured commercial products. Commercial operations of SDI were initiated with an agreement with a Corporate Partner (a large integrated chemical company) to develop an immunoassay test to detect certain corrosion causing bacteria. This product was introduced in late 1991 and SDI purchased all rights and technology related to this product in 1994. In February 1992, SDI entered into a $3.9 million Corporate Partnership with EM Industries, Inc. (an affiliate of Merck KGaA, Darmstadt, Germany) for the development and manufacture of a line of immunoassay test kits capable of identifying and quantifying targeted priority pollutants. The first products under this agreement were introduced in 1993. Through August 1996, these products were manufactured by SDI and marketed by EM Industries, Inc. In September 1996, EM Industries, Inc. and SDI reached an agreement whereby the February 1992 agreement was terminated, together with EM Industries, Inc.'s marketing rights thereunder, in exchange for certain specified royalty payments to EM Industries, Inc. and shares of SDI common stock. The marketing activities with respect to such products in the U.S. are now the responsibility of the Company. Since 1992, the Company has entered into research and development agreements with multiple Corporate Partners that have led to the introduction of various products to the water quality, industrial testing, agricultural and other markets. These agreements generally provide that sales and marketing costs associated with a new product are borne by the Corporate Partner. In addition, the Company currently sells directly other products that it has independently developed or acquired. The Company believes that its competitiveness has been enhanced through the combinations of talents, technology and resources resulting from the mergers and acquisitions described above. The Company has also achieved meaningful economies of scale, operates from consolidated facilities in Newark, DE and is now offering its customers the most appropriate test for each specific customer application. Another key strategy that SDI used to develop its business was the formation in 1991 of TSD BioServices, a joint venture between SDI and a subsidiary of Taconic Farms of Germantown, NY. Taconic Farms is a privately held company whose business is the production and sale of mice and rats, primarily to the research community. In 1996, the joint venture was dissolved and SDI's interests were distributed into a wholly owned subsidiary, TSD BioServices, Inc. ("TSD"). The mission of TSD is to supply antibodies, especially monoclonal antibodies, immunochemical reagents and related services to medical diagnostic and pharmaceutical companies, as well as the research community. TSD's primary facility occupies approximately 8,000 square feet of space in Newark, DE. On February 26, 1999, the Company completed the acquisition of HTI Bio-Products, Inc., a privately held manufacturer of custom and proprietary antibody products and services located near San Diego, CA ("HTI") (See "Recent Developments"). 18 The Company believes that its products in the water quality, industrial testing and agricultural markets are unique and fill potentially large, unmet needs. The Company also believes that its products and technology currently being developed have broad application in diverse markets. The Company believes that its established product base, quality manufacturing expertise, experienced sales and marketing organization, established network of distributors, Corporate Partner relationships and proven research and development expertise will be critical elements of its potential future success. The Company experiences a seasonal pattern to its business. Sales of industrial and agricultural products are highest during the summer months with the lower levels of activity occurring during the winter months. Accordingly, revenues in any particular quarter may not be indicative of revenues for any subsequent quarter during the year, or for the year. As sales of the Company's analytical tests for water-soluble polymers (which are generally not affected by seasonal patterns) and agricultural products to other parts of the world develop over the next few years, the Company expects its seasonal fluctuations to become gradually less pronounced. Recent Developments During the second half of 1998, several significant developments occurred in the market for testing for Genetically Modified Organisms (GMOs) and the labeling of food products in Europe. Earlier in 1998, the European Commission adopted rule 1139/98, which requires over 22,000 food processors to test ingredients for the presence of GMOs and label products accordingly beginning March 1, 1999. During the third quarter of 1998, the Company devoted significant resources to educate regulators and industry representatives concerning the features and benefits of its products, immunoassay-based, protein test kits to detect the presence of GMOs. This work continued during the fourth quarter of 1998 and the Company achieved several milestones during the second half of 1998. The Joint Research Centre's Food Products Unit of the Institute for Health and Consumer Protection (JRC-IHCP, the regulatory authority responsible for the validation of test methods) reviewed the Company's product plans and expressed interest in validating protein-based test methods like those proposed by the Company. Second, to commercially validate its methods, the Company licensed certain proprietary proteins from leading agricultural biotechnology companies and conducted data trials with several commercial laboratories throughout Europe. In addition, the Company participated in a JRC-IHCP sponsored validation study of its Soya test kit, which involved 38 qualified laboratories throughout Europe. These trials are common in the food testing industry and are generally referred to as "Ring Studies". During the fourth quarter, the Company and these laboratories completed these studies. The JRC-IHCP has informed the Company that its products have been validated to detect the presence of the tested traits at the thresholds (concentrations) established in the Ring Study protocol. The Company has now begun to manufacture and market these products throughout Europe, focusing its sales efforts on the early adopters and opinion leaders in the food process industry as described below. The Company began to introduce its technology and products to the leading food processors in Europe during the third quarter of 1998. Prospective customers have shown interest in the technology's ability to detect the presence of GMOs above a specified threshold level, its fast time-to-result and its cost advantages. This work continued during the fourth quarter of 1998. The Company has formed a product focus group consisting of three of the largest food companies in the world. The Company expects that this group will be utilized to refer prospective customers to the Company's technology and products. On February 26, 1999, the Company completed the acquisition of HTI. HTI had 1998 revenues of $5.7 million and pre tax profits of approximately $800 thousand. These results are preliminary and the Company expects to complete an audit on or before May 15, 1999. HTI, a primary manufacturer of antibodies and biochemicals, was founded in 1990. HTI's products and services include custom antibody production, bulk antibody and biochemical products. The Company believes that these capabilities will afford it the ability to leverage its manufacturing costs, particularly in its test-strip production for agricultural, food and water quality product lines. These products utilize large quantities of polyclonal antibodies that the Company previously purchased from third parties. The Company believes that HTI's product lines will also enhance the Company's exisiting capabilities in antibody production by adding extensive polyclonal products and services to the monoclonal products and services provided by its TSD BioServices subsidiary ("TSD"). The customers of HTI are complementary to TSD's and share common characteristics in that they are primarily pharmaceutical and biotechnology companies developing important medical diagnostics as well as leading medical research facilities. The Company believes that the combination and integration of these customer relationships will allow both TSD and HTI to offer their customers broader product offerings and will help establish these companies as a single source for all of their customers' antibody and biochemical requirements. Similarly, the Company believes the integration of these operations will result in significant cost savings and be accretive to earnings. 19 Results of Operations Year ended December 31, 1998 versus year ended December 31, 1997 Revenues: Revenues increased $1.3 million in 1998 or 9% over 1997. This increase is the result of a $1.5 million (12%) increase in product related revenues, offset by a $164 thousand (10%) decrease in contract and other revenues. Product related revenues increased to $14.2 million from $12.7 million in 1998 from 1997. This growth in product revenues is primarily attributable to increases in sales of products in the agricultural category (tests to detect traits in genetically engineered plants) of $1.3 million (62%), TSD BioServices category (custom monoclonal antibody production and purification) of $651 thousand (31%) and sales of other products (includes the sale of a line of antibodies for $400 thousand to a major customer and the $600 thousand sale of pre-commercial Macra Lp(a) test kits pursuant to the June 1998 supply agreement with a major customer, both occurring during the second quarter of 1998) $1.1 million (196%), all increases over the 1997 revenues recorded in these categories. These increases were partially offset by decreases in the Industrial/Chemical category $354 thousand (7%), and Water Quality category $1.2 million (41%), when compared to the 1997 revenues recorded in these categories. The decline in contract and other revenues is principally the result of the Company's focusing its efforts on the food testing market during the second half of 1998. During the second half of 1998, the Company strategically refocused its efforts and devoted significant resources to enter the European Market for food testing to detect the presence of GMOs in agricultural commodities and food fractions that are used to manufacture finished food products. This focus resulted in a reduction in contract and other revenues and an increase in research and development, selling, general and administrative expenses. Operating Expenses: Operating expenses increased $2.3 million (18%) in 1998, from $13.0 million in 1997 to $15.3 million in 1998. This increase is primarily related to an increase in the general business activity that occurred during the year and described below. Manufacturing expenses, which include the costs of products sold, increased $917 thousand (17%) in 1998 to $6.2 million. Increased costs in materials, labor and overhead were associated with the mix of products sold in 1998 versus 1997. Research and development expenses increased $342 thousand (22%) to $1.9 million in 1998 from $1.6 million in 1997. This increase was due to the higher costs of labor and materials associated with additional staff required to develop new, and modify existing, products for the Company's entry into the European GMO food testing market. Selling, general and administrative expenses increased $1.0 million (17%) to $7.2 million in 1998. Increased costs for public relations, sales consulting, advertising and travel were recorded as the Company increased its exposure in the markets it serves. Additional expenses were incurred as efforts in the second half of 1998 were focused on the Company's entry into the European market for GMO testing. The Company reorganized its sales and marketing efforts in the second half of 1998 to focus on this rapidly emerging opportunity. This major reorganization included closing two sales offices in the industrial sales group, consolidating certain sales responsibilities to the Company's headquarters and reassigning other individuals to cover the agricultural market. Net Interest and Other Income: Net interest and other income increased $82 thousand (30%) in 1998 to $356 thousand, from the $274 thousand earned in 1997. This increase is due to an increase in the level of invested balances maintained throughout the year. Net Income: Net income decreased $896 thousand (53%) in 1998 to $781 thousand, from income of $1.7 million reported in 1997. This decrease in net income is attributable to the increased costs, particularly research and development and selling, general and administrative expenses, related to the Company's entry into the European food market which more than offset increases in revenues, all as described above. 20 Year ended December 31, 1997 versus year ended December 31, 1996 Revenues: Revenues increased $8.6 million in 1997 or 147% over 1996. This increase is attributable to the increase in business activity after the mergers (Note 3) and the increased sales of products in the Company's emerging markets. Product revenues increased $9.3 million or 273% due primarily to increases in total product sales in emerging markets (tests to detect, (i) proprietary polymers and (ii) traits in genetically engineered plants in agriculture) to $3.1 million from $845 thousand in 1996. Contract and other revenues decreased $718 thousand or 29% to $1.7 million in 1997. The 1996 volume includes approximately $667 thousand in revenues from transactions between EnSys and SDI prior to the merger. These businesses were integrated during 1997. Operating Expenses: Operating expenses decreased $1.4 million or 9.7% in 1997 to $13.0 million. This decrease is attributable to the inclusion in 1996 of a one-time charge of $8.3 million to write-off research and development costs acquired in connection with the mergers. Excluding this charge, operating expenses increased $6.9 million or 112% as a result of increases in manufacturing costs of $2.5 million or 87%, research and development expenses of $11 thousand or 0.7% and selling, general and administrative expenses of $4.4 million or 253%. These increases are all attributable to the higher costs of operation (principally additional personnel and related costs) of the combined companies. Net Interest and Other Income: Net interest and other income increased $88 thousand in 1997 from $186 thousand in 1996. This increase is attributable to the increase in invested funds acquired through the mergers, offset by $178 thousand of equity income recorded in 1996 as a result of the TSD BioServices dissolution (Note 3). Net Income: Net income increased $10.1 million in 1997 to $1.7 million from a loss of $8.4 million. This increase in net income is attributable to the higher volume of revenues reduced in part by the increased costs and the one-time write-offs in 1996 all associated with the mergers. Liquidity The Company's working capital, which consists principally of cash, cash equivalents and short term investments, increased by $755 thousand in 1998 to $10.2 million at December 31, 1998 from $9.4 million at December 31, 1997. This increase is attributable to the increases in accounts receivable of $494 thousand (16%), inventories of $308 thousand (20%) and other current assets of $295 thousand (170%), and by reductions in accrued expenses of $165 thousand (17%) and other current liabilities of $40 thousand (33%). These were partially offset by decreases in cash, cash equivalents and short term investments of $364 thousand (6%), and an increase in accounts payable of $183 thousand (30%). Under the terms of the agreement to acquire HTI, the Company paid approximately $8.1 million in cash, issued 556,286 shares of Series B preferred stock and assumed approximately $100 thousand of long term debt. The preferred shares convert into common shares on a 1-for-1 basis at any time at the option of the holder, and at the option of the Company when the closing price of the Company's stock exceeds $3.50 for a period of 10 days, and carry a cumulative, annual cash dividend of $0.175 per share and a liquidation preference. The Company is also obligated to pay a percentage of net sales of certain products over the next three years, not to exceed $3 million. Approximately $6 million of acquisition financing has been provided by the Company's commercial bank, with the balance coming from existing cash on hand. For the year ended December 31, 1998, the Company satisfied all of its cash requirements from cash available and on-hand, and from a financing agreement with its commercial bank of $323 thousand for specific equipment purchases and leasehold improvements. At December 31, 1998, the Company had $265 thousand in long-term debt and stockholders' equity of over $13.1 million. The Company believes it has, or has access to sufficient assets to meet its operating requirements for the forseeable future. The Company's ability to meet its long-term capital requirements will depend on a number of factors including the success of its current and future products, the focus and direction of its research and development program, competitive and technological advances, future relationships with Corporate Partners, government regulation, the Company's marketing and distribution strategy and the success of the Company's plan to make future acquisitions. Accordingly, no assurance can be given that the Company will be able to meet the future liquidity requirements that may arise from these inherent and similar uncertainties (see Note 16 to the Consolidated Financial Statements). 21 Year 2000 Issues The Company is aware of and is evaluating many of the "Year 2000" issues associated with both information technology ("IT") and non-IT systems which could cause problems and network failures should the systems fail to recognize year designations after 1999. The Company is currently reviewing its own computer, communication, software and operating systems to determine if they are Year 2000 compliant. The Company has planned system-wide testing in the first quarter of 1999 for all internal network hardware and software, all enterprise system software and all user workstation hardware and software. During the second quarter of 1999, the Company will test all internal and OEM equipment. Any system failures will be addressed when detected. The Company expects that absent unforeseen negative results of its testing, its systems will be Year 2000 compliant no later than July 31, 1999. Accordingly the Company has not conducted any contingency planning. The Company relies primarily on third party provided software purchased and licensed commercially, therefore the Company believes its Year 2000 risks are minimal. As a result its historical and estimated future costs of remediation are now, and are not expected to become, material. The Company will continue to contact critical suppliers, collaborators and partners to determine if their operations, as they relate to the Company, are Year 2000 compliant. The Company cannot presently estimate the impact of the failure of such third parties to be Year 2000 compliant. Although the Company will take all practical measures to prevent problems related with the Year 2000 programming issues, such problems and failures may occur which could seriously affect the Company's progress. Because of the unprecedented nature of such problems, the extent of the effect on the Company's progress cannot be certain. 22 ITEM 8.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 1998 (in thousands, except share and per share data) 1. BACKGROUND: Business Strategic Diagnostics Inc. (the "Company") develops, manufactures and markets immunoassay based test kits for rapid and inexpensive detection of a wide variety of substances in the water quality, industrial and agricultural markets. Basis of Presentation The Company is the entity resulting from the combination of Strategic Diagnostics Inc. ("SDI") Ohmicron Corporation ("Ohmicron") and EnSys Environmental Products, Inc. ("EnSys"). The historical financial statements presented herein include the consolidated financial statements of SDI for all periods and the actual results of Ohmicron from August 30, 1996 (Note 3) and EnSys from December 30, 1996 (Note 3). As used herein, unless the context requires otherwise, the Company collectively refers to Strategic Diagnostics Inc. and its subsidiaries for the periods indicated. All significant intercompany balances and transactions have been eliminated in consolidation. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND CERTAIN BALANCE SHEET INFORMATION: Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Basic and Diluted Income per Share The Company has adopted Statement of Financial Standards ("SFAS") No. 128, "Earnings per Share," which requires dual presentation of basic and diluted earnings per share ("EPS") for complex capital structures on the face of the statement of operations. Basic EPS is computed by dividing net income or loss by the weighted-average number of common shares outstanding during the period. Diluted EPS is similar to basic EPS except that the effect of converting or exercising all potentially dilutive securities is also included in the denominator. The Company's calculation of diluted EPS includes the effect of converting preferred stock and exercising stock options and warrants into common shares. Outstanding options to purchase 30,000 shares of Common stock at $3.25 were excluded from the computation of diluted earnings per share, as the options' exercise price was greater than the average market price of the common shares. Statements of Cash Flows The Company considers all highly liquid instruments purchased with an original maturity of three months or less to be cash equivalents. F-7 Accounts Receivable As of December 31, 1998, 1997 and 1996, the allowance for doubtful accounts was $97, $120 and $180, respectively. In 1998, 1997 and 1996, approximately $23, $60 and $2 of write-offs were charged to this allowance which was offset by approximately $114, $0 and $81 charged to earnings in each of the respective years. If receivables become uncollectible or unbillable, the Company's policy is to charge these write-offs against the allowance. The Company continually reviews the realizability of its receivables and charges current period earnings for the amount deemed unrealizable. At December 31, accounts receivable consisted of the following: 1998 1997 1996 ----------- ------------ -------- Accounts receivable $ 3,152 $ 2,745 $ 1,739 Unbilled accounts receivable 501 414 595 ------------ ------------ -------- $ 3,653 $ 3,159 $ 2,334 ============ ============ ======== Inventories The Company's inventories, which consist primarily of test kit components and accessories, are valued at the lower of cost or market. Cost is determined using the first in, first out method. Realization of the Company's inventories is dependent upon the successful marketing of its products. At December 31, inventories consisted of the following: 1998 1997 1996 ------------ ----------- --------- Raw materials $ 700 $ 619 $ 626 Work in progress 93 51 356 Finished goods 1,062 877 575 ------------ ----------- --------- $ 1,855 $ 1,547 $ 1,557 ============ =========== ========= Property and Equipment Property and equipment are stated at cost. Depreciation and amortization is computed using the straight-line method over the estimated useful lives (generally three to five years) of the assets. Leasehold improvements are depreciated over the shorter of, the lease term or the estimated useful life. Revenue Recognition Product related revenues which include the sale of immunoassay-based test kits are generally recognized upon shipment. Included in product related revenues are also the sale of antibodies and immunochemical reagents which are sold through longer term development agreements. These revenues are recognized on a percentage of completion method. Contract revenues recorded under the Company's collaborative agreements are recognized upon the completion of certain performance requirements of the contracts. License revenue is recognized upon transfer of such licenses. Research and Development Research and development costs are charged to expense as incurred. Accounting for Income Taxes Deferred income tax assets and liabilities are determined based on differences between the financial statement reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The measurement of deferred income tax assets is reduced, if necessary, by a valuation allowance for any tax benefits which are not expected to be realized. The effect on deferred income tax assets and liabilities of a change in tax rates is recognized in the period that such tax rate changes are enacted. F-8 Other Income Other income of $178 was recorded in 1996, for the Company's equity in the income of TSD BioServices (Note 3). Comprehensive Income On January 1, 1998, the Company adopted SFAS No. 130, "Reporting Comprehensive Income." SFAS No. 130 establishes standards for reporting and display of comprehensive income or loss and its components in financial statements. 3. MERGERS AND ACQUISITIONS: Merger with EnSys Environmental Products, Inc. On December 30, 1996, the Company merged with and into EnSys Environmental Products, Inc. (the "Merger"). The Merger agreement provided that SDI common and preferred stockholders receive .7392048 shares of EnSys stock for each share of SDI Common or Preferred Stock. This resulted in the former SDI stockholders owning 5,780,136 shares of EnSys Common Stock and 2,164,362 shares of EnSys Series A Convertible Preferred Stock or approximately 52% of the 15,219,532 voting shares outstanding after the Merger. In addition to the common and preferred stock noted above, current SDI option and warrant holders received options and warrants to purchase .7818026 shares of EnSys Common Stock for each option or warrant held. Upon consummation of the Merger, SDI option and warrant holders received options and warrants for the purchase of 383,216 and 599,644 shares, respectively, of EnSys Common Stock. The difference in exchange ratios between stockholders and option and warrant holders is due to the stock preferences received by SDI's preferred stockholders upon exchange of their shares. The cost of receiving these preferences was shared by all SDI stockholders upon exchange of their shares, but was not borne by the SDI option and warrant holders. The Merger was accounted for as a purchase transaction with SDI as the acquiring company. Based on the $1.75 per share closing price of EnSys Common Stock on October 14, 1996, (date of transaction public announcement) the estimated total purchase price of EnSys was $16,133, which consists of the following: (i) the $12,731 market value of the outstanding shares of EnSys Common Stock (7,275,034 shares multiplied by $1.75 per share), (ii) the $328 fair value of the outstanding options and warrants to purchase EnSys Common Stock and (iii) estimated transaction costs of approximately $3,074. Since SDI is the acquirer for accounting purposes, the EnSys options and warrants are required to be valued for purchase accounting purposes as if they are additional consideration in the transaction. The valuation for EnSys options and warrants was provided by an investment banking firm using a traditional valuation approach. Of the approximately $3,074 of estimated transaction costs, approximately $457 relates to severance payments to former EnSys employees, $362 to facility termination and moving and $36 to employee relocation. In connection with the Merger, approximately 35 EnSys employees were terminated in December 1996. In connection with the Merger, all identifiable assets acquired by SDI including intangible assets were assigned a portion of the cost of the acquired company based on an independent valuation of EnSys' assets. Such allocation included the identification and evaluation of each development project to determine if technological feasibility had been achieved and if there were any alternative future uses. EnSys' primary research and development focus at the time of the merger, the "One Step" assay, was evaluated and it was determined that technological feasibility had not been achieved. In addition, since alternative uses of this developmental technology did not exist, the costs of such technology were charged to expense in accordance with SFAS No. 2. Based on the foregoing purchase price, the amount allocated to acquired research and development of $4,353 was charged to the statement of operations at December 30, 1996, the effective date of the Merger. The remaining amount of intangible assets of approximately $1,167 included approximately $472 for developed technology, $55 for assembled workforce and $640 for goodwill. The intangible assets purchased are amortized on a straight-line basis over 7-10 years. F-9 Acquisition of Ohmicron Corporation On August 30, 1996, SDI acquired Ohmicron and certain of its wholly owned subsidiaries for 2,268,456 shares of common stock. Prior to the acquisition, Ohmicron spun-off certain assets and liabilities of another of its wholly-owned subsidiaries, Ohmicron Medical Diagnostics, Inc. The acquisition of Ohmicron was recorded as a purchase using the fair value of the SDI common stock issued to Ohmicron. The total purchase price of approximately $4,503, including transaction and other costs of $533, has been allocated to the fair market value of the assets acquired and liabilities assumed. Based on the foregoing purchase price, the amount allocated to acquired research and development of $3,913 was charged to the statement of operations at the time of the acquisition. In connection with the Ohmicron transaction, all identifiable assets acquired including intangible assets were assigned a portion of the cost of the acquired company based on an independent valuation of Ohmicron's assets. Such allocation included the evaluation of each development project identified to determine if technological feasibility had been achieved and if there were any alternative future uses. Based on this analysis, it has been determined that technological feasibility has not been achieved, and that alternative uses of this developmental technology do not exist. The cost of such technology has therefore been charged to expense in accordance with SFAS No. 2, "Accounting for Research and Development Costs." The remaining amount of intangible assets of approximately $590 included approximately $384 for developed technology, $103 for assembled workforce and $103 for goodwill. The intangible assets purchased are amortized on a straight-line basis over 7-10 years. The fair market value of the common stock issued to Ohmicron was based on several factors including recent equity transactions, as well as the subsequently negotiated merger with EnSys. The redeemable convertible preferred stock was mandatorily redeemable and received dividends, registration rights and senior liquidation rights to the common stock (see Note 11). The common stock was valued at $1.75 per share reflecting a discount from the redeemable convertible preferred stock due to the difference in preferences between the two classes of stock. TSD BioServices Dissolution In October 1996, SDI entered into an agreement with Taconic Farms, Inc. ("Taconic") to dissolve TSD BioServices; a partnership between Taconic and SDI and to liquidate its assets, in connection with which certain of the rights and assets were distributed to SDI. Upon dissolution, certain rights and assets formerly owned by the joint venture were placed in a wholly-owned subsidiary of SDI. The agreement to dissolve TSD Bio Services provides that each of the former partners receive rights to perform services that were considered to be either a core part of that partner's expertise, or an area in which the partner wanted to increase its market presence or technical competency. The dissolution agreement also provided that certain services previously provided by TSD BioServices, such as ascites production and sales and marketing, would be subcontracted to Taconic by SDI in the future based on established fees set annually. For accounting purposes, this transaction was treated as a purchase, with the consideration provided being SDI's investment of $338, which approximates the fair market value of the assets received. Unaudited Pro Forma Combined Results of Operations The following table summarizes the unaudited pro forma combined results of operations for the year ended December 31, 1996, assuming that the Merger, the Ohmicron acquisition and the TSD dissolution had occurred on January 1, 1996: Year Ended December 31 ---------------------- 1996 ---- (unaudited) Revenues $ 12,700 ======== Net Loss $ (5,973) ======== Basic and Diluted Net loss per share $ (0.47) ======== F-10 The above pro forma information excludes the $8,266 one-time charge to earnings for acquired research and development. The shares used in computing pro forma net loss per share assumes that the Merger with EnSys, the acquisition of Ohmicron and the TSD BioServices dissolution had occurred January 1, 1996. Supplemental Disclosure of Cash Flow Information The following table displays the net non cash assets that were acquired during 1996 as a result of the Merger and the Ohmicron Acquisition: Non cash (assets) liabilities: Short term investments $ (5,710) Receivables (808) Inventories (1,318) Property and equipment (443) Restricted cash (126) Note receivable (357) Intangibles (2,135) Accounts payable 1,483 Accrued expenses including acquisition costs 1,128 Deferred revenue 100 Capital lease obligations 152 --------------- (8,034) Issuance of common stock 17,107 Acquired research and development (8,266) Net cash acquired in business acquisitions $ 807 =============== 4. SHORT-TERM INVESTMENTS: As of December 31, 1998 and 1997, short-term investments consisted primarily of commercial paper. Contractual maturities of the Company's investments as of December 31, 1998 are $2,740 in 1999, $174 in 2000, $244 in 2001 and $832 from 2002 and beyond. The Company considers these investments as being available-for-sale in accordance with SFAS No. 115 "Accounting for Certain Investments in Debt and Equity Securities." Available-for-sale securities are carried at fair value, based on quoted market prices, with unrealized gains and losses reported as a separate component of stockholders' equity. As of December 31, 1998 and 1997, unrealized gains were not material to the financial statements. Interest income and other realized gains were $362, $310, and $11 in 1998, 1997, and 1996, respectively. 5. PROPERTY AND EQUIPMENT: As of December 31, property and equipment consisted of the following: 1998 1997 ------------- ------------- Equipment $ 1,518 $ 1,071 Furniture and fixtures 66 66 Leasehold improvements 502 288 ------------- ------------ Less- Accumulated depreciation and amortization (1,251) (929) ------------- ------------ $ 835 $ 496 ============= ============ Depreciation expense was $322, $391, and $91 in 1998, 1997, and 1996 respectively.

NOTES PAYABLE: In October 1994 and April 1995, the holders of the redeemable convertible preferred stock provided $500 and $1,000, in working capital loans to the Company. These notes bore interest at 9% and 10% per annum, respectively, and each became due during 1995. In addition, 87,349 and 223,372 warrants were issued, respectively, for the purchase of common stock of the Company at an exercise price of $2.37 per share. The warrant values deemed for accounting purposes were $23 and $75, respectively, which were recorded as an asset and amortized over the term of the loans. The warrants have an exercise period of five years. In January 1996, the Company converted the $1,500 of Notes Payable and $124 of accrued interest into 685,952 shares of redeemable convertible preferred stock (Note 11). F-12 10. LONG-TERM DEBT: The Company entered into two financing agreements with its commercial bank during 1998, pursuant to the purchase of equipment and specific leasehold improvements. The maturities on these financing agreements are for 48 and 60 months. These notes are secured with Certificates of Deposit (CD), purchased by the Company and bear an interest rate of 1% over the purchased CD rate. As of December 31, 1998, the maturities of long-term debt are listed below: 1999 $ 83 2000 80 2001 79 2002 74 2003 32 --------------- 348 Less- Current portion of long-term debt obligations (83) --------------- Long-term debt $ 265 =============== Interest expense was $20, $36, and $3 in 1998, 1997, and 1996 respectively. 11. SERIES A PREFERRED STOCK: In June 1993, the Company sold 1,267,208 shares of redeemable convertible preferred stock and received proceeds of $3,000 less $47 of transaction costs. In connection with the 1996 financing, the Company converted the $1,500 of notes payable and $124 of accrued interest into 685,952 shares of redeemable convertible preferred stock at $2.37 per share (Note 9) and received an additional investment of $500 for the purchase of 211,202 shares less transaction costs of $27. All such shares were redeemable with cumulative dividends, at the option of the holders, as defined, beginning in 1998. Dividends have been accreted through the Merger (Note 3). In connection with the Merger, the redeemable convertible preferred stock plus cumulative dividends were converted into 2,164,362 shares of a newly issued class of Series A Preferred Stock ("Series A"). The Series A has no redemption provisions outside the control of the Company. As a result, the Series A is classified as a component of stockholders' equity. Each share of Series A is convertible into one share of common stock at the option of the holder at any time, or at the option of the Company if the closing share price of the Company's common stock exceeds $4.50 per share for a period of 45 business days. The Series A carries an aggregate and per share liquidation preference of $6,378 and $2.95, respectively, as of December 31, 1998. The Series A contains no annual dividend provisions and is only redeemable in the event the Company converts the Series A into securities of a lesser value, as defined. 12. STOCK OPTIONS AND WARRANTS: Stock Options The Company has two stock option plans (the "1993 Plan" and the "1995 Plan") which authorize the granting of incentive and nonqualified stock options to officers, key employees, directors and consultants. Incentive stock options are granted at not less than 100% of fair market value at the date of grant (110% for stockholders owning more than 10% of the Company's common stock). Nonqualified stock options are granted at not less than 85% of fair market value at the date of grant. All previously issued SDI options were converted into the 1995 Plan. A maximum of 1,700,000 shares of common stock are issuable under the 1995 Plan and options to purchase up to 300,000 shares of common stock had been reserved under the 1993 Plan. F-13 Certain additional options have been granted outside the plans. These options generally follow the provisions of the 1995 Plan. Information with respect to the stock options granted under the plans and options granted separately from the plans is summarized as follows: Price Aggregate Number Range Proceeds --------------- ----------------- --------------- Balance, December 31, 1995 397,288 0.19 - 0.64 122 Options acquired in conjunction with the Merger 461,023 0.25 - 7.50 1,226 Granted 200,000 2.00 - 2.20 420 Cancelled (14,072) 0.64 (9) ------------ ---------------- ------------- Balance, December 31, 1996 1,044,239 $ 0.19 - $ 7.50 $ 1,759 Granted 545,000 1.88 1,022 Cancelled (204,198) 0.19 - 7.50 (576) Exercised (25,502) 0.19 - 0.64 (7) ------------- ---------------- ------------- Balance, December 31, 1997 1,359,539 $ 0.19 - $ 3.25 $ 2,198 ------------ --------------- ------------- Granted 350,000 2.00 - 2.63 888 Cancelled (22,377) 0.64 - 1.88 (34) Exercised (93,172) 0.19 - 1.88 (34) ------------ --------------- ------------- Balance, December 31, 1998 1,593,990 $ 0.19 - $ 3.25 $ 3,018 ============ =============== ============= As of December 31, 1998, options covering 799,722 shares were exercisable with an aggregate exercise price of $1,252 and 385,772 shares were available for future grant under the plans. For options granted, the Company recognizes as deferred compensation the excess of the deemed value for accounting purposes of the common stock issuable upon the exercise of options over the aggregate exercise price of such options. The deferred compensation is amortized over the vesting period of the options. Options Outstanding Options Exercisable ------------------------------- ------------------------ Weighted Average Shares ----------------------------- Wtd.

Effective January 1, 1995, the Company adopted the disclosure requirement of this pronouncement. Had compensation cost for the Company's stock option plans been determined based upon the fair value at the grant date for awards under SFAS 123, the Company's net income (loss) applicable to common stockholders for 1998, 1997 and 1996 would have been $190, $1,493, and $(9,113) and diluted net income (loss) per share applicable to common stockholders would have been $.01, $0.10, and $(2.15), respectively. Because the SFAS 123 method of accounting has not been applied to options granted prior to January 1, 1995, the resulting pro forma compensation cost, and thus pro forma net income (loss), may not be representative of that to be expected in future years. F-14 The weighted average fair value at the date of grant for options granted during 1998, 1997 and 1996 is estimated at $1.97, $1.37 and $1.46 per share, respectively, using the Black-Scholes option-pricing model. The assumptions used in the Black-Scholes model are as follows: dividend yield of 0%, expected volatility of 94% in 1998 and 80% in 1997 and 1996, risk-free interest rate of 6.1% in 1998, 6.4% in 1997 and 6.4% in 1996, and an expected option life of 5 years in 1998 and 6 years in 1997 and 1996. Warrants In December 1994, in connection with a prior collaboration agreement, the Company issued to Conoco a warrant that enables Conoco to purchase 164,179 shares of the Company's common stock for an exercise price of one dollar. In connection with this exchange, the Company recorded a charge of $105 in 1994 in the statement of operations reflecting the fair value of the warrant. If Conoco exercises this warrant, and the Company completes an equity financing with aggregate proceeds of $7 million or greater, then Conoco has the right to require the Company to repurchase the warrant at a price equal to 164,179 shares multiplied by the price per share received in the equity financing. The warrant expires in November 1999. In connection with the original issuance of redeemable convertible preferred stock and notes payable in October 1995 and April 1995 which were subsequently converted to redeemable convertible stock in January 1996, the Company granted warrants to purchase a total of 429,992 shares of common stock at an exercise price of $2.37. Of these warrants, 312,716 were outstanding as of December 31, 1998. The warrants expire five years from the dates of grant. In addition, at December 31, 1998, the Company maintains 3,530 of outstanding warrants. These warrants are exercisable at $4.96 per share and expire in 2001. 13. EM COLLABORATIVE AGREEMENT: In February 1992, SDI entered into an agreement with EM Industries, Inc. (an affilitate of Merck KGaA, "EM") for the development and manufacture of a product line of immunoassays capable of identifying and quantifying certain substances found on the priority pollutant list published by the Environmental Protection Agency. In connection with this agreement, the Company received $400 in 1996, for the achievement of certain defined development milestones. In September 1996, the Company acquired the product rights to the DTECH(R) product line from EM in exchange for a royalty payment based on sales of specified products into selected markets and 48,048 shares of common stock. 14.

TSD BIOSERVICES TRANSACTIONS: TSD purchased certain supplies, raw materials and services from Taconic and the Company. In 1996, the Company included in revenues $53 of contract and other revenues resulting from transactions with TSD. In October 1996, TSD was dissolved (Note 3). In 1991, TSD entered into a five-year management agreement with each of its partners. The agreements provided that the partners could charge TSD BioServices for work performed on behalf of the partnership by any of the partners' principals. TSD BioServices partners elected not to charge TSD BioServices for these and certain other expenses related to the partnership, but rather elected to absorb such costs in the parent organizations. Such costs were immaterial and the management agreement was terminated in 1996. 16. COMMITMENTS AND CONTINGENCIES: The Company leases its office and manufacturing facilities and other equipment under operating leases. Rent expense for the years ended December 31, 1998, 1997 and 1996, was $598, $466 and $250, respectively. Future commitments under these non-cancelable leases at December 31 are as follows: 1999 $569 2000 436 2001 383 2002 351 2003 362 2004 and thereafter 1,288 ----- $3,389 ====== F-16 The Company is party to various claims arising in the ordinary course of business. Although the ultimate outcome of these matters is presently not determinable, management, after consultation with legal counsel, does not believe that the outcome of these matters will have a material adverse effect on the Company's financial position or results of operations. 17. RETIREMENT SAVINGS PLAN: In 1992, the Company instituted a retirement savings plan qualified under Section 401(k) of the Internal Revenue Code. The plan allows for eligible employees to contribute a portion of their gross wages to the plan. The Company matches employees' contributions on a 50% basis up to 6% of gross wages. In 1998, 1997 and 1996, the Company recognized expense of $77, $76 and $51, respectively, associated with this plan. 18. INCOME TAXES: As of December 31, 1998, the Company had federal net operating loss carryforwards, including those acquired (Note 3), of approximately $15,540, which begin to expire as follows: 2002 $ 489 2003 489 2004 1,362 2005 2,565 2006 2,603 2007 2,584 2008 1,182 2009 2,081 2010 2,185 --------- Total $15,540 ========= The amount of the net operating loss carryforwards which can be utilized in any one period, if any, will be limited by federal tax regulations since a cumulative change in ownership of more than 50% has occurred within a three year period. The benefits of the utilization of acquired net operating losses, if any, will be recorded as a reduction of the remaining unamoritized intangibles that were acquired in the transaction in which the utilized net operating losses were acquired. Any benefits obtained in excess of the remaining related intangibles will be reported as a reduction in the income tax provision during the year in which management determines that it is more likely than not that these benefits will be realized. As of December 31, 1998 approximately $4,400 of future utilization, if any, of acquired net operating losses will be recorded as a reduction of the related acquired intangibles. The net operating loss carryforwards differ from the accumulated deficit principally due to differences in the recognition of certain research and development expenses, depreciation and amortization, other non-deductible reserves and the accretion of preferred stock for financial and federal income tax reporting. Significant components of the Company's deferred tax assets as of December 31 are as follows: 1998 1997 ---- ----- Net operating loss carryforwards 7,288 5,429 Amortization and depreciation 699 517 Non-deductible reserves 55 127 Inventory costs not currently deductible 63 129 ------ ------ Total deferred tax assets 8,105 6,202 Valuation allowance (8,105) (6,202) ------- ------- Net deferred tax assets - - ======= ======= F-17 The following table summarizes the significant differences between the U.S. Federal statutory rate and the Company's effective tax rate for financial statement purposes: 1998 1997 1996 ---- ---- ---- Statutory tax rate 34.0% 34.0% (34.0)% State taxes, net of U.S. Federal benefit .5 - .1 Write-off of acquired research and development - - 33.5 Increase in (utilization of) net operating loss carryforwards - (.6) (3.2) Changes in net valuation reserve (35.4) (34.9) 3.1 Other, net .9 1.5 .5 ------- ------ --------- - % - % - % ======= ====== ========= Management continually reviews the valuation allowance and will recognize deferred tax benefits only as reassessment indicates that it is more likely than not that these benefits will be realized. The total amount of future taxable income in the U.S. necessary to realize the Company's gross deferred tax assets is approximately $18,000. Management believes that the recorded valuation allowance is consistent with the provisions of SFAS 109, "Accounting for Income Taxes." 19. SALE OF TECHNOLOGY In July 1998, the Company entered into an agreement to sell its analytical test to detect concentrations of lipoprotein (a) to a biotechnology company. The purchaser has an extensive portfolio of diagnostic assays and an established sales and distribution network targeted to physicians and clinical laboratories. This agreement follows an exclusive distribution and supply agreement with the same company that became effective June 30, 1998. The Company will continue to manufacture and sell the product until the distributor is prepared to manufacture the product (estimated to be approximately March 1999). The Company records revenues under the exclusive distribution and supply agreement as the products are shipped. Thereafter, the Company will receive a royalty for the life of the product. At December 31, 1999, under the July 1998 agreement, the Company and the purchaser will determine the cash purchase price to be paid to the Company for its right, title and interest in the product. Such purchase price is based on a multiple of sales volumes achieved during the second half of 1999. In July 1998 the Company purchased the intellectual and licensing rights to the product for $380. The Company expects to record the sale of the asset during the fourth quarter of 1999, after the sales price has been determined. All royalties under the agreements will be recorded in the quarter the products are sold. 20. SUBSEQUENT EVENTS On February 26, 1999, the Company completed the acquisition of HTI Bio-Products, Inc., a privately held manufacturer of custom and proprietary antibody products and services located near San Diego, CA (HTI). Under the terms of the agreement to acquire HTI, the Company paid approximately $8.1 million in cash, issued 556,286 shares of Series B preferred stock and assumed approximately $100 of long term debt. The preferred shares convert into common shares on a 1-for-1 basis at any time at the option of the holder, and at the option of the Company when the closing price of the Company's stock exceeds $3.50 for a period of 10 days, and carry a cumulative, annual cash dividend of $0.175 per share and a liquidation preference. The Company is also obligated to pay a percentage of net sales of certain products over the next three years, not to exceed $3 million. Approximately $6 million of acquisition financing has been provided by the Company's commercial bank, with the balance coming from existing cash on hand.
