On September 29, 2000, STC Technologies, Inc., a Delaware corporation ("STC"), and Epitope, Inc., an Oregon corporation ("Epitope"), were merged (the "Merger") into OraSure Technologies, Inc. ("OraSure Technologies" or the "Company"), a new corporation that was organized on May 5, 2000 under Delaware law solely for the purposes of combining STC and Epitope and changing the state of incorporation of Epitope from Oregon to Delaware. The companies were merged pursuant to an Agreement and Plan of Merger, dated May 6, 2000 (the "Merger Agreement"), by and among Epitope, STC and the Company. The stockholders of STC and Epitope approved the Merger Agreement on September 29, 2000. The Merger was structured as an all-stock transaction valued at $260 million. As a result of the Merger, (i) each share of STC common stock was converted into the right to receive five and two hundred ninety-six one thousandths (5.296) shares of the Company's Common Stock and (ii) each share of Epitope common stock was converted into the right to receive one share of the Company's Common Stock. The Merger has been accounted for as a "pooling of interests." The Merger is expected to leverage the Company's expertise in oral fluid technology, infectious disease testing and substance abuse testing. By building upon the complementary product portfolios, technologies and sales infrastructures of Epitope and STC, the Company intends to open up new markets in the United States and other countries and strengthen its position in key markets such as the rapidly expanding point-of-care market. In particular, the proprietary up-converting phosphor technology contributed by STC has broad applications for oral fluid testing. With the increased sensitivity and accuracy of this technology, the Company believes it can continue to expand the menu of tests available for oral fluid point-of-care testing. This same basic technology is also expected to be of significant benefit to other medical diagnostic manufacturers outside the expertise contributed by Epitope and STC. For many of these additional applications, OraSure Technologies plans to license these other companies to provide an ongoing revenue stream of license fees and royalties. PRODUCTS OraSure Technologies develops, manufactures and markets oral fluid specimen collection devices using its proprietary oral fluid technologies, proprietary diagnostic products including in vitro diagnostic tests, and other medical devices. These products are sold in the United States and certain foreign countries to public and private-sector clients, clinical laboratories, physician offices, and hospitals, and for workplace testing. OraSure Technologies' business focuses on the following principal platform technologies: (1) the OraSure(R) oral fluid collection device, (2) the OraQuick(R) rapid diagnostics test device, and (3) the new up-converting phosphor technology ("UPT"), including its first application, UPlink(TM), a lateral flow testing system for various analytes. In addition, the Company sells certain other products, including the Histofreezer(R) cryosurgical system, certain immunoassay tests and reagents for insurance risk assessment and forensic toxicology applications, an oral fluid Western Blot confirmatory test for HIV-1, and the Q.E.D. (R) Saliva Alcohol Test. OraSure(R) Collection Device - ---------------------------- The Company's OraSure oral fluid collection device is used in conjunction with screening and confirmatory tests for HIV-1 antibodies and other analytes. The OraSure device consists of a small, treated cotton-fiber pad on a nylon 1

handle that is placed in a person's mouth for two minutes. The device collects oral mucosal transudate ("OMT"), a serum-derived fluid that contains higher concentrations of antibodies than saliva. As a result, OMT testing is a highly accurate method for detecting HIV infection and other analytes. The Company believes that oral fluid testing has several significant advantages over blood or urine-based testing systems for both healthcare professionals and individuals being tested, including eliminating the risks of needle-stick accidents, providing a noninvasive collection technique, requiring minimal training to administer, providing rapid and efficient collection in almost any setting, and eliminating the cost of a trained healthcare professional to administer. The Company has received clearance from the U.S. Food and Drug Administration ("FDA") to sell the OraSure oral fluid collection device to professional markets for use with a laboratory-based enzyme immunoassay ("EIA") screening test for HIV-1 antibody detection. HIV-1 antibody detection using the OraSure collection device involves three steps: (1) collection of an oral fluid specimen using the OraSure device, (2) screening of the specimen for HIV-1 antibodies at a laboratory with an EIA screening test, and (3) laboratory confirmation of any positive screening test results with the OraSure Western Blot confirmatory test (described below). A trained healthcare professional then conveys test results and provides appropriate counseling to the individual who was tested. The Company has also received clearance for use of the OraSure collection device with EIAs to test for cocaine and for cotinine (a metabolite of nicotine) in oral fluid specimens. The Company markets the OraSure collection device in the insurance market for the screening of life insurance applicants for HIV-1, cocaine and cotinine, and in the physician office and public health markets for HIV-1 testing. A collection device substantially similar to the OraSure device is included as part of the Company's Intercept(TM) oral fluid drug test service. The Company has received FDA clearance to use the Intercept collection device with EIAs to test for drugs of abuse commonly known as the NIDA-5 (i.e. cannabinoids (marijuana), cocaine, opiates, amphetamines, and phencyclidine ("PCP")) and for benzodiazepines, barbiturates, and methadone. Intercept was launched for the workplace testing, public health, criminal justice and drug rehabilitation markets in February 2000. In 1999, the Company entered into an exclusive agreement with LabOne, Inc., pursuant to which the Company agreed to exclusively sell, and LabOne agreed to exclusively purchase and distribute, Intercept collection devices and associated reagents for drugs-of-abuse testing in the workplace testing market in the United States and Canada. Under the agreement, LabOne provides all laboratory services necessary to test oral fluid specimens collected by customers including screening and confirmatory studies. The term of the agreement runs until December 31, 2002, with automatic yearly renewals unless either party gives notice at least 180 days prior to the end of the then-current term. The Company believes that the Intercept service has several advantages over certain competing products for drugs-of-abuse testing, including its non-invasive nature, the ease of maintaining a chain-of-custody without embarrassment to the person being tested, and the lack of requirement for specially prepared collection facilities. The availability of an oral fluid test is intended to allow workplace administrators to test for impairment on demand, eliminate scheduling costs, and streamline the testing process. OraQuick(R) - -------- The OraQuick device is the Company's recently developed rapid test designed to test an oral fluid, whole blood or serum/plasma sample for the presence of various antigens. The device includes a porous flat pad used to collect an oral fluid specimen. After collection, the pad is inserted into a vial containing a pre-measured amount of developer solution and allowed to develop. When whole blood, serum or plasma is to be tested, a loop collection device is used to collect the sample and mix it in the developer solution, after which the collection pad is inserted into the solution. The specimen and solution then flow through the testing device where test results are observable in approximately 20 minutes. No laboratory-based EIA is required, as the OraQuick test is visually read shortly after the specimen is collected. The first product utilizing this technology is the OraQuick HIV-1/2 device, a rapid test for the presence of antibodies against HIV-1 and HIV-2. On June 23, 2000, the Company received approval for an Investigational Device Exemption ("IDE") from the FDA authorizing the commencement of formal clinical trials for the OraQuick HIV-1/2 2

device. Clinical trials in the United States are underway, although the Company has experienced difficulty in recruiting a sufficient number of known positive subjects. Due to the critical need for an FDA-cleared rapid HIV test, the Company, after consultation with the FDA and the Centers for Disease Control and Prevention ("CDC"), has decided to submit an initial application for FDA clearance for testing of whole blood, serum and plasma during the second quarter of 2001. This decision was based on OraSure Technologies' belief that a whole blood clinical trial could be completed more quickly than one involving oral fluid. The Company is continuing its oral fluid clinical trials and expects to submit an application for FDA clearance of oral fluid tests during the third quarter of 2001. The Company has received approval from the CDC to use the OraQuick HIV-1/2 test in a CDC-sponsored IDE. The CDC has identified several key areas for use of the OraQuick HIV-1/2 device in the IDE, including certain public hospitals in five U.S. metropolitan areas with relatively high HIV sero-prevalence among pregnant women, AIDS service organizations, community-based organizations, outreach programs, and selected hospital emergency departments and outpatient clinics. At the CDC's Rapid Diagnostic's Meeting in February 2001, the CDC released the most recent results of its ongoing multi-product, rapid HIV test study. These results indicated a 100% sensitivity and 99.5% specificity for the OraQuick device with whole blood samples. In July 2000, the Company introduced the OraQuick HIV-1/2 device for sale outside the United States at the International AIDS Conference in Durban, South Africa. Clinical tests for the OraQuick HIV-1/2 device have been completed in Thailand, with the results demonstrating 100% sensitivity and 99.9% specificity. The Company intends to market the OraQuick HIV-1/2 product in the hospital, physician office and public health markets focusing initially on international markets. The Company recently entered into an agreement for the distribution of the OraQuick HIV-1/2 device in Sub-Saharan Africa, with $5 million in revenues expected from minimum quantities required to be purchased under the agreement during the first year. Distribution agreements have been entered into or are being pursued in numerous other countries. The Company may need to obtain licenses or other rights under, or to enter into distribution or other business arrangements in connection with, certain HIV-2 and lateral flow patents, some of which have been obtained, in order to market the OraQuick HIV-1/2 device in the United States and certain other countries. See the Section entitled "Risk Factors - Patent Issues Affecting OraQuick" for a further discussion of these issues. UPT(TM)and UPlink(TM) - ----------------- UPT(TM) Technology. UPT is a proprietary label detection platform being - ------------------- developed by the Company that uses phosphor particles to detect minute quantities of various substances such as drugs, proteins, and DNA. UPT is based on the use of a unique patented technology which is used to detect the presence of specific substances in tests designed by the Company. UPT utilizes the same particle shell that is coated onto a television screen, but the internal chemistry of the particle has been changed. These changes result in a particle that is excited by infrared light as compared to an ultraviolet light source for television. OraSure Technologies and its research partners have developed phosphorescent particles that up-convert infrared light to visible light, which the Company is using to develop several applications. Phosphor particles have been used for decades in television screens and in fluorescent light bulbs. When ultraviolet light strikes the phosphor-coated area in a screen or bulb, it excites the particles and colored light is produced. The Company's patented improvements on this base technology employ chemical changes inside the phosphor particles so that infrared light can be used to produce a colored signal. This use of infrared light to create a colored signal is called up-conversion as opposed to down-conversion, which occurs in phosphors designed to be used with ultraviolet light. The use of infrared light to excite the phosphor particles and produce a colored light signal creates an important competitive advantage for the technology in biological systems, especially human clinical diagnostics. Existing enzyme or fluorescent-based assays employ visible or ultraviolet light to generate the signals from the enzyme substrate or fluorescent molecules used as reporter signals in these systems. The disadvantage of using light in the 3

visible or ultraviolet portion of the spectrum is that often molecules in the cells or samples for analysis can also produce colored light (background interference) from these excitation sources. When this occurs, a non-specific signal is generated which dilutes or obscures the signal of interest for the diagnostic test being administered. Because up-conversion does not occur in nature, biological samples and specimens will not produce light, and therefore, will not cause background interference when excited by infrared light. The Company believes that UPT overcomes some of the limitations of other diagnostic detection methods and offers features not commercially available today. The fact that UPT testing produces zero background interference dramatically increases the potential sensitivity of any test system. UPT particles also offer the following other key competitive features: o Ability to detect biological markers for several substances simultaneously o Stability in a variety of biological specimens o A permanent test record not subject to fading o Applicability to a variety of instrument platforms o A low-cost detection method that is easy to use o Compatibility with alternative testing matrices such as oral fluid, blood or others o Ability to miniaturize the test platform The Company has reached important milestones in the development of UPT, including improving the manufacturing process to produce UPT particles, working to optimize UPT particle coating techniques, producing four distinct colors of UPT particles to begin experiments on the simultaneous detection of multiple biological markers to permit multiplexing, demonstrating initial feasibility for the use of UPT particles in drugs-of-abuse, infectious disease, cancer, and limited DNA detection applications, and developing a UPT collector, test cassette and reader for a variety of applications. UPlink(TM). UPlink is the Company's first product application based on UPT. - ---------- UPlink is designed to be a rapid, point-of-care system utilizing a collector, lateral flow test cassette, and reader, which provides instrument-read quantitative results in about 10 minutes on a variety of samples, including without limitation oral fluid, blood, serum, urine and stool samples. In March 2000, the Company signed a research and development agreement with Drager Sicherheitstechnik GmbH ("Drager"), a European manufacturer and supplier of medical and safety technology products for health care and industrial applications, to develop and optimize the UPlink system for rapid detection of drugs of abuse in oral fluid. The UPlink system developed with Drager is expected to be marketed to law enforcement officials as a system for rapidly assessing whether a subject is under the influence of one or more drugs of abuse. As part of the research and development agreement, the Company received a non-refundable fee and will receive additional fees upon achievement of technical milestones. Upon successful completion of such research and development activities, Drager has the option to become the Company's exclusive worldwide distributor of the UPlink drugs-of-abuse test cassette and reader developed under the research and development agreement to law enforcement officials for use in rapidly assessing whether a subject is taking one or more drugs-of-abuse substances. In December 2000, the Company submitted an application for 510(k) clearance from the FDA for its UPlink reader and three oral fluid drugs-of-abuse assays - cocaine, opiates and amphetamines. A similar application for two additional oral fluid assays -marijuana and PCP - is expected to be submitted to the FDA during the second quarter of 2001. The Company expects to commence commercial sales of UPlink for oral fluid drugs-of-abuse testing in the second half of 2001. In September 2000, OraSure Technologies signed a research and development agreement with Meridian Bioscience, Inc. (formerly Meridian Diagnostics, Inc.) ("Meridian"), a fully integrated medical diagnostics company. Under this agreement, the Company and Meridian plan to develop a broad range of UPlink point-of-care tests for the rapid detection of parasites, and gastrointestinal and upper respiratory diseases. Pursuant to a related supply agreement, Meridian will distribute worldwide the readers and lateral flow cassettes developed under the research and development agreement. The Company will receive payments upon achievement of certain milestones and royalties from the sale of the readers and testing devices. OraSure Technologies has commenced work on the development of 4

two tests under the research and development agreement and expects to submit an application for FDA 510(k) clearance of a number of tests in the third quarter of 2001. The Company also expects to begin shipping tests for international distribution by Meridian during the second half of 2001. Histofreezer(R) - ------------ In 1991, the Company became the exclusive U.S. distributor of the Histofreezer Portable Cryosurgical System, a low-cost alternative to liquid nitrogen and other eradication methods for removal of benign epidermal lesions. In June 1998, the Company acquired the Histofreezer product from Koninklijke, Utermohlen, N.V., The Netherlands. As part of the acquisition, the Company established a sales office in Reeuwijk, The Netherlands, and is now integrating a dealer network in more than 20 countries worldwide. Histofreezer is a mixture of two environmentally friendly cryogenic gases in a small aerosol canister. When released, these gases are delivered to a specially designed foam bud, cooling the bud to -55C. The frozen bud is then applied to the lesion for 20 to 40 seconds creating localized destruction of the target area. Histofreezer is sold in two sizes of canisters. Histofreezer sales have been targeted to primary care physicians such as pediatricians, general and family practitioners, and other physician segments that traditionally referred patients to dermatologists to remove warts. The Company has established a national network of distributors to reach the physician office market in the United States Immunoassay Tests and Reagents - ------------------------------ The Company develops and sells immunoassay tests in two formats, MICRO-PLATE and AUTO-LYTE(R), to meet the specific needs of its customers. Both types of assays are sold as finished kits. AUTO-LYTE tests are sold as bottles of reagents. The reagents are used with commercially available automated analytical instruments which are manufactured by a variety of third parties. AUTO-LYTE tests provide medium sensitivity to detect substances comprised of small molecules. AUTO-LYTE is typically used in high volume, automated, commercial reference laboratories. Test results are produced faster, allowing for higher throughput. In the MICRO-PLATE kit, the sample to be tested is placed into a microwell along with the reagents. The result of the test is determined by the color of the microwell upon completion of the reaction. Controlling the reaction involves the use of a variety of reagents by laboratory personnel. Test results are analyzed by any of a variety of commercially available laboratory instruments which are generally not provided by the Company. The test kit is commonly used for high sensitivity measurement of substances comprised of both large and small molecules. OraSure Technologies has used this testing format to develop tests that detect substances in urine, serum, and oral fluid specimens. The MICRO-PLATE assays generally have greater sensitivity than the AUTO-LYTE assays. OraSure Technologies currently markets the MICRO-PLATE oral fluid test for use in screening life insurance applicants to test for two of the most important underwriting risk factors: cocaine and cotinine (a metabolite of nicotine). The Company sells the reagents to insurance testing laboratories, which may in turn provide the laboratory testing to insurance companies, often in combination with the OraSure oral fluid collection device. AUTO-LYTE tests are marketed for use in testing urine samples for cocaine and cotinine and for performing a variety of urine chemistries for insurance risk assessment purposes. The Company also develops, manufactures, and sells toxicology and drugs-of-abuse tests in the MICRO-PLATE format. These MICRO-PLATE tests can be performed on commonly used instruments and can detect drugs in urine, serum, and sweat specimens. MICRO-PLATE tests are also used as part of the Intercept product line to detect drugs-of-abuse in oral fluid specimens. The Company's toxicology and drugs-of-abuse test products are currently sold in the forensic toxicology, criminal justice, drug rehabilitation and workplace testing markets. Whenever possible, the Company enters into multi-year purchase agreements and reagent rental agreements with its customers. These agreements generally are entered into with a laboratory which has agreed to purchase a minimum number of tests over a two-to-five-year period. The Company also offers these customers the option of a reagent rental agreement pursuant to which the Company provides the tests as well as analytical laboratory equipment. 5

Western Blot Confirmatory Tests - ------------------------------- The Company markets an oral-based HIV-1 Western Blot confirmatory test that received FDA clearance in 1996. This test uses the original specimen collected with the OraSure oral fluid collection device to confirm positive results of initial OraSure HIV-1 screening tests. The oral fluid Western Blot HIV-1 confirmatory test is marketed under an exclusive arrangement with Organon Teknika Corporation. In February 2001, the Company announced the indefinite suspension of the production of EPIblot, a serum-based Western Blot HIV-1 confirmatory test. The serum Western Blot product accounted for approximately 5% of the Company's 2000 revenue, but has been consistently unprofitable because of low production yields and the high cost of ensuring the quality of the end product. Q.E.D.(R) Saliva Alcohol Test - ----------------------------- The Q.E.D. Saliva Alcohol Test is an on-site, cost-effective test device which is an alternative to breath or blood alcohol testing. The test is a quantitative, saliva-based method for the detection of ethanol, and has been cleared for sale by the FDA and the U.S. Department of Transportation ("DOT"). The product received a Clinical Laboratory Improvement Act of 1988 ("CLIA") waiver in 1997. Each Q.E.D. test kit contains a collection stick which is used to collect a sample of saliva and a disposable detection device that displays results in a format similar to a thermometer. The Q.E.D. device is easy to operate and instrumentation is not required to read the result. The product line comes in two testing ranges, 0 to 0.145% and 0 to 0.30% blood alcohol, and produces results in two to five minutes. The markets for alcohol testing are relatively small and fragmented with a broad range of legal and procedural barriers to entry. Markets range from law enforcement testing to workplace testing of employees in safety sensitive occupations. The Q.E.D. test has been successfully adopted by end users in the petroleum, heavy construction, trucking, and retail businesses because it is a cost-effective, portable, easy-to-administer, quantitative testing method. Typical usage situations include pre-employment, random, post-accident, reasonable-cause, and return-to-duty testing. PRODUCTS UNDER DEVELOPMENT OraSure Applications - -------------------- Oral mucosal transudate contains many constituents found in blood serum, although in lower concentrations. The Company therefore believes the OraSure device is a platform technology with a wide variety of potential applications beyond HIV-1 and drugs-of-abuse testing. For example, the OraSure device may be useful for the diagnosis of a variety of infectious diseases or conditions in addition to HIV-1, such as viral hepatitis, syphilis and diabetes. The National Institutes of Health ("NIH") approved a grant of approximately $1 million to fund Phase II of the Company's project to develop a screening and confirmation test for syphilis using an oral fluid sample collected with the OraSure device. The Company previously received a grant of $118,000 from the NIH as funding for Phase I of this project, which was completed in 2000. OraSure Technologies has also entered into an agreement with LabOne to develop a laboratory-based oral fluid screening test for Hepatitis C using the OraSure collection device. The Company is presently developing an improved formulation of the OraSure device, to be called OraSure II, which will be designed to improve the effectiveness of collecting and preserving human antibodies in oral fluid for infectious disease testing and is expected to be more cost effective. The Company is also developing additional drug assays to be used in connection with its Intercept product line in the insurance testing, criminal justice and drug rehabilitation markets. OraQuick Platform - ----------------- The Company believes that OraQuick has significant potential as a rapid test for physician offices, hospitals and other professional use. Like OraSure, the Company believes that OraQuick provides a platform technology that can 6

be modified for detection of a variety of infectious diseases in addition to HIV, such as viral hepatitis, syphilis and other diseases. UPT and UPlink Development - -------------------------- The Company is in the final stages of developing an UPlink system for rapid drugs-of-abuse testing under its agreement with Drager and for its own commercial applications in the U.S. The Company has commenced development of three tests for infectious diseases and expects to commence development of additional tests later in 2001 for other infectious diseases under its agreement with Meridian. Other potential applications of UPT include thyroid testing, cancer testing, cardiac testing and therapeutic drug monitoring. In addition, the Company is studying the feasibility of using UPT labels for the detection of infectious diseases with DNA probes. Western Blot Confirmatory Test - ------------------------------ The Company is developing an improved Western Blot confirmatory test for HIV-1, which will be designed for use on oral fluid, whole blood, and serum\plasma specimens. RESEARCH AND DEVELOPMENT In 2000, research and development activities focused on the development of the OraQuick HIV-1/2 rapid test (including significant clinical trials, validation and scale-up expenses), development of the UPlink reader, test cassette and collector for drugs-of-abuse applications, DNA feasibility studies, and regulatory compliance. In addition, the Company also performed research and development activities with respect to additional Intercept products, new antibody development, and improvements to existing products. The Company supplements its own research and development activities by funding external research. The Company has been funding, and will continue to fund, research at Leiden University, SRI International, and Lehigh University. Research and development expenses totaled approximately $10.4 million in 2000, $5.6 million in 1999, and $4.5 million in 1998. SALES AND MARKETING The Company's strategy is to reach its major target markets through a combination of direct sales, strategic partnerships, and independent distributors. The Company's marketing strategy is to raise awareness of its products through a mix of trade shows, print advertising, and distributor promotions to support sales to each target market. The Company markets its products in the United States and internationally. Product revenue attributable to customers in the United States amounted to $24.8 million, $21.4 million, and $17.8 million in 2000, 1999 and 1998, respectively. Revenues attributable to international customers amounted to $4.0 million, $2.7 million, and $2.6 million in 2000, 1999 and 1998, respectively. Insurance Testing - ----------------- The Company currently markets the OraSure oral fluid collection device for use in screening life insurance applicants in the U.S. and internationally to test for three of the most important underwriting risk factors: HIV-1, cocaine, and cotinine (a metabolite of nicotine). The Company sells the devices to insurance testing laboratories, which in turn provide the devices to insurance companies, usually in combination with testing services. The Company maintains a direct sales force that promotes use of the OraSure device directly to insurance companies. Insurance companies then make their own decision regarding which laboratory to use to supply their collection devices and testing services. 7

Because insurance companies are in various stages of their adoption of the OraSure device, there exists a wide range of policy limits where the product is being applied. Some insurance companies have chosen to extend their testing to lower policy limits where they did not test at all before, while others have used OraSure to replace some of their blood-based testing. The Company's sales force continues to encourage additional insurance companies to use OraSure and to extend the use of the product by existing customers. Several companies have expanded use of OraSure in "Preferred" products in addition to the $1 million and higher dollar policy amounts. This expansion is attributable to several factors, including increasing comfort with the reliability of oral fluid testing following its successful use, the high quality of test results, the low cost of oral fluid testing relative to blood tests, and the ease of use of OraSure. The Company also sells its AUTO-LYTE and MICRO-PLATE assays and reagents in the insurance testing market directly to laboratories. AUTO-LYTE assays are used principally to test urine samples for cotinine and other metabolites and to perform urine chemistries for risk assessment purposes. MICRO-PLATE assays are used principally to test oral fluid specimens collected with the OraSure device for cocaine and cotinine. Public Health and Physician Office Markets - ------------------------------------------ The Company's sales personnel market its products directly to customers in the public health market. This market consists of a broad range of clinics and laboratories and includes states, counties, and other governmental agencies, colleges and universities, correctional facilities and the military. There are also a number of similar organizations in the public health market such as AIDS service organizations and various community-based organizations set up primarily for the purpose of encouraging and enabling HIV-1 testing. To better serve this market, the Company has entered into agreements with LabOne and Heritage Labs to provide prepackaged OraSure test kits, with prepaid laboratory testing and specimen shipping costs included. The Company also began distributing the OraQuick HIV-1/2 device in the public health markets internationally through independent distributors in December 2000. The Company sells the Histofreezer product line to distributors that market to more than 150,000 primary care physicians and podiatrists in the U.S. Major U.S. distributors include McKesson HBOC, Physicians Sales & Service, Bergen Brunswig, and Henry Schein. Internationally, the Company markets Histofreezer in a number of countries through a network of distributors, the largest of which is B. Braun. Substance Abuse - --------------- The Company's substance abuse products are marketed into the workplace testing, forensic toxicology, criminal justice, and drug rehabilitation markets. The forensic toxicology market consists of 250 - 300 laboratories including federal, state and county crime laboratories, medical examiner laboratories, and reference laboratories. The criminal justice market consists of a wide variety of entities in the criminal justice system that require drug screening, such as pre-trial services, parole and probation officials, drug courts, prisons, drug treatment programs and community/family service programs. The Company has entered into a contract with LabOne to assemble and distribute Intercept collection kits and associated reagents for drugs-of-abuse testing in the workplace testing market in the United States and Canada. Intercept and Q.E.D. are also marketed through direct sales and other distributors. International Markets - --------------------- The Company sells a number of its products into international markets primarily through distributors with knowledge of their local markets. Principal markets include insurance testing, public health and laboratory testing. The Company assists its distributors in registering the products in each country and provides training and support materials. The Company's international marketing program includes direct assistance to distributors in arranging for laboratory services, cooperation from screening test manufacturers, and performance of Western Blot confirmatory tests when necessary. 8

SIGNIFICANT PRODUCTS AND CUSTOMERS Several different products have contributed significantly to the Company's financial performance, accounting for 15% or more of total revenues during the past three years. The Company's OraSure oral fluid collection devices, Histofreezer, and immunoassay tests and reagents accounted for total revenues of approximately $11.2 million, $6.8 million, and $6.7 million in 2000, $7.8 million, $5.7 million, and $6.2 million in 1999, and $7.2 million, $4.8 million, and $4.8 million in 1998, respectively. The Company has one customer that has accounted for 10% or more of total revenues. During 2000, the Company's sales to LabOne, Inc., accounted for approximately 23% of the Company's total revenues. The Company believes that its relationship with this customer is strong and that it will purchase comparable or increasing values of the Company's products for the foreseeable future. However, there can be no assurance that sales to this customer will not decrease or that this customer will not choose to replace the Company's products with those of competitors. The loss of this customer or a significant decrease of products purchased by it could have a material adverse effect on the Company. SUPPLY AND MANUFACTURING The Company has entered into an agreement with a contractor in Oregon for the assembly and supply of OraSure oral fluid collection devices until December 31, 2002. This agreement will automatically renew for additional annual periods unless either party provides timely notice of termination prior to the end of an annual period. The Company believes that other firms or the Company would be able to manufacture the OraSure device on terms no less favorable than those set forth in the agreement with the Oregon contractor in the event that this contractor were to be unable to continue manufacturing this product, although a change in manufacturer of the OraSure device would require FDA review and clearance which could require significant time to complete. In February 2001, the Company announced its plans to realign its manufacturing operations, which will include the elimination of the manufacturing of OraQuick in the Beaverton, Oregon facility, the installation of automated manufacturing equipment for OraQuick in Bethlehem, Pennsylvania, and the addition of manufacturing capacity in Thailand. In connection with this realignment, the Company has entered into a supply agreement for the manufacture of OraQuick HIV-1/2 testing devices in Thailand. This agreement has an initial term of one year from the date production commences, which will automatically renew for additional annual periods unless either party provides a timely notice of termination prior to the end of an annual period. The Company believes that other firms would be able to manufacture the OraQuick test on terms no less favorable than those set forth in the Thailand agreement in the event that the Thailand contractor were to be unable to continue manufacturing this product. The Company expects to assemble readers, test cassettes and collectors used in the Company's UPlink rapid test and to package this product for shipment at the Company's Bethlehem facilities. The Company's oral fluid Western Blot HIV confirmatory test is manufactured in the Company's Beaverton, Oregon facilities. The HIV-1 antigen needed to manufacture the Company's Western Blot HIV confirmatory test kits is available from only a limited number of sources. Organon Teknika Corporation, the exclusive distributor of the test kits, is required to supply the Company's requirements for antigen for the term of its distribution agreement with the Company, which originally extended to March 31, 2001. OraSure Technologies and Organon Teknika are currently negotiating certain amendments to the agreements, including an extension of their terms. If for any reason Organon Teknika should no longer be able to supply the Company's antigen needs, management believes the Company would be able to obtain its own supply of antigen at a competitive cost, although a change in the antigen would require FDA approval. Histofreezer is manufactured in The Netherlands by Koninklijke, Utermohlen, N.V., the company from which the Company acquired the product in 1998. The Company purchases the product pursuant to an exclusive production agreement between the two companies. The production agreement provides that Koninklijke, Utermohlen, N.V. shall be the exclusive supplier of the Histofreezer product until June 1, 2003. The Company believes that additional manufacturers of the Histofreezer product are available on terms no less favorable than the terms of the production 9

agreement with Koninklijke, Utermohlen, N.V. in the event that Koninklijke, Utermohlen, N.V. were to be unable to continue manufacturing the Histofreezer product. The Company's AUTO-LYTE and MICRO-PLATE assays are manufactured at its Bethlehem, Pennsylvania, facility. The Company manufactures the test components and assembles and packages the tests for distribution. The Company's tests require the production of highly specific and sensitive antibodies corresponding to the antigen of interest. Antibodies are produced commercially by injecting a vaccine consisting of a purified, specific antigen into one of a variety of animals. The injected animal's immune system then manufactures antibodies, which are contained in blood samples and are collected on a routine basis, purified through the use of a chemical process, and prepared for use in various diagnostic products. Substantially all of the Company's antibody requirements are produced by contract suppliers. However, in 1999, the Company began to develop its own in-house monoclonal and polyclonal antibody capabilities. The Company believes that it maintains adequate reserves of antibody supplies and believes it has access to sufficient raw materials for these products. AUTO-LYTE test kits are manufactured by adding specific antibodies to chemical solutions which are then packaged as a defined volume of liquid in a plastic container for use in laboratory equipment. MICRO-PLATE test kits are produced by placing purified antibodies onto a plastic container which is sent to customers in multiples of ninety-six tests along with a set of reagents necessary to control the reaction. The reaction container is sealed in a foil package and placed in a box with the reagents. The Q.E.D. test is manufactured, packaged, and shipped from the Company's Bethlehem facility. EMPLOYEES As of December 31, 2000, the Company had 210 full-time employees, including 42 in sales, marketing, and client services; 73 in research and development; 77 in operations, manufacturing, quality control, purchasing and shipping; and 18 in administration and finance. Sixteen of the Company's employees hold Ph.D. degrees. The Company's employees are not represented by a collective bargaining agreement. On February 1, 2001, the Company announced that in connection with the realignment of its manufacturing operations, employee headcount would be reduced in its Beaverton, Oregon office by approximately 35 persons, or 33% of staffing at that facility. This reduction is expected to occur through layoffs and attrition during the first half of 2001. The Company expects to increase staffing at its Bethlehem, Pennsylvania facility as a result of the start-up of manufacturing operations at that location. COMPETITION The diagnostic industry is a multi-billion dollar international industry and is intensely competitive. Many of the Company's competitors are substantially larger and have greater financial, research, manufacturing, and marketing resources. Important competitive factors for the Company's products include product quality, price, ease of use, customer service, and reputation. Industry competition is based upon scientific and technological capability, proprietary know-how, access to adequate capital, the ability to develop and market products and processes, the ability to attract and retain qualified personnel, and the availability of patent protection. A few large corporations produce a wide variety of diagnostic tests and other medical devices and equipment, a larger number of mid-size companies generally compete only in the diagnostic industry, and, finally, a significant number of small companies produce only a few diagnostic products. As a result, the diagnostic test industry is fragmented and segmented. The future market for diagnostic tests is expected to be characterized by consolidation, greater cost consciousness, and tighter reimbursement policies. The purchasers of diagnostic products are expected to place increased emphasis on lowering costs, automation, service, and volume discounts. The increased complexity of the market is expected to force many competitors to enter into joint ventures or license certain products or technologies. Competition may intensify as technological advances are made and become more widely known and as products reach the market in greater numbers. Furthermore, new testing methodologies could be developed in the future that 10

render the Company's products impractical, uneconomical or obsolete. There can be no assurance that the Company's competitors will not succeed in developing or marketing technologies and products that are more effective than those developed by the Company or that would render its technologies and products obsolete or otherwise commercially unattractive. In addition, there can be no assurance that competitors will not succeed in obtaining regulatory approval for these products, or in introducing or commercializing them before the Company. Such developments could have a material adverse effect on the Company's business, financial condition, and results of operations. Competition in the market for HIV testing is intense and is expected to increase. The Company believes that the principal competition will come from existing laboratory-based blood tests, point-of-care whole blood rapid tests, urine-based assays, or other oral fluid-based tests that may be developed. The Company's competitors include specialized biotechnology firms as well as pharmaceutical companies with biotechnology divisions and medical diagnostic companies. Several companies market or have announced plans to market oral specimen collection devices and tests outside the United States and have announced plans to seek FDA approval of such tests in the United States. The Company expects the number of devices competing with its OraSure device to increase as the benefits of oral specimen-based testing become more widely accepted. The FDA has approved an HIV-1 screening test for use with a urine sample. In June 1998, the FDA notified Cambridge Biotech Corp. (acquired by Calypte, Inc. in December 1998) that it had approved the use of its HIV-1 Western Blot confirmatory test for use with urine samples. Although the sensitivity and specificity are less than blood-based or oral fluid tests, urine testing will compete in the same markets as the Company's products. The Company believes that urine collection can be logistically more difficult, inconvenient and potentially embarrassing for the individual being tested, and that privacy and chain-of-custody issues are further impediments to routine use of urine-based HIV tests. The Company cannot predict the impact of the availability of urine-based tests on the HIV testing market or on sales of the Company's products. Calypte, Inc. and Bio-Rad Laboratories, Inc. manufacture HIV Western Blot confirmatory tests, and Waldheim Pharmazeutika manufactures immuno-fluroescent HIV confirmatory tests, which competed with the Company's HIV-1 Western Blot serum-based confirmatory test kits and could compete with the Company's improved Western Blot confirmatory test once developed. Significant competitors in the rapid assay HIV testing market include Abbott Laboratories, the Ortho Diagnostics division of Johnson & Johnson, and Trinity Biotech. In the insurance risk assessment market, the Company's AUTO-LYTE homogeneous assays for cocaine and cotinine compete with reagents from Microgenics, Inc. (a subsidiary of Sybron Lab Products). The Company's AUTO-LYTE homogeneous assays for beta-blockers and thiazide as well as MICRO-PLATE heterogeneous assays for the detection of cocaine, cotinine and IgG in oral fluid are the only assays available in the marketplace. In urine chemistries, the Company's significant competitors include The Diagnostics Systems Group of Olympus America Inc. and Roche Diagnostics. The Company's MICRO-PLATE drugs-of-abuse reagents are targeted to forensic testing laboratories where sensitivity, automation, and "system solutions" are important. In the past, these laboratories have typically had to rely on radioimmunoassay test methods to provide an adequate level of sensitivity. Radioimmunoassays require radioactive materials, which have a short shelf-life and disposal problems. The Company's MICRO-PLATE tests meet the laboratories' sensitivity needs, run on automated equipment, and are delivered to the laboratory as a complete "system package" of reagents and instrumentation (known as a "reagent rental" transaction) to meet the specific needs of each customer. Rental reagent transactions are usually offered only by companies significantly larger than OraSure Technologies. In the forensic toxicology market, the Company competes with both homogeneous and heterogeneous tests manufactured by a host of companies. Significant competitors in the market for homogeneous assays include Dade Behring, Abbott Diagnostics, Roche Diagnostics, and Immunalysis. 11

The Intercept drug testing service competes with a wide variety of drug testing products and services. These competitors can be divided into two groups: 1) rapid tests, and 2) laboratory-based services. Within each product or service group, drug testing can be further divided into testing matrices such as urine, hair, sweat and oral fluid. Major competitors in the laboratory-based drug testing market are Quest Diagnostics, LabCorp., Psychemedics, PharmChem, and Medtox Laboratories. The drugs-of-abuse application of UPlink will compete with other rapid drug assays. Major competitors in the rapid drug testing market include American Biomedica, Roche Diagnostics, Inc., and Biosite Diagnostics. Within the sub-segment of oral fluid drugs-of-abuse testing, Intercept competes with Avitar, Inc., which markets a rapid test called Oral Screen(TM) to the workplace and criminal justice markets, and LifePoint, Inc., which has announced plans to sell a reader-based saliva test panel that will include alcohol testing. Q.E.D. has two direct competitors, Roche Diagnostics, Inc. and Chematics. These companies offer semi-quantitative saliva-based alcohol tests and both have received DOT approval. Indirect competitors who offer breath testing equipment include Intoximeters, Drager, and CMI. Although there are lower priced tests on the market that use oral fluid or breath as a test medium, these tests are qualitative tests that are believed to be substantially lower in quality and scope of benefits than the Company's Q.E.D. test. The Histofreezer product's patented delivery system and warmer operating temperature than liquid nitrogen provide the Company with the opportunity to target sales to primary care physicians, such as family practitioners, pediatricians, and podiatrists. The Company does not target sales to dermatologists because they have the volume of patients required to support the capital costs associated with a liquid nitrogen delivery system. There is limited competition for convenient cryosurgical products for wart removal in the primary care physician market. Competition for the Histofreezer product includes portable cryosurgical systems from CryoSurgery, Inc. and Ellman International. In addition, liquid nitrogen is used by medical professionals to remove warts and other benign skin lesions. Lastly, patients may purchase various over-the-counter products to treat warts at home. PATENTS AND PROPRIETARY INFORMATION The Company seeks patent and other intellectual property rights to protect and preserve its proprietary technology and its right to capitalize on the results of its research and development activities. The Company also relies upon trade secrets, know-how, continuing technological innovations, and licensing opportunities to provide it with competitive advantages in its selected markets and to accelerate new product introductions. Respecting the patent and intellectual property rights of others, the Company regularly searches for third-party patents in its fields of endeavor to shape its own patent and product commercialization strategies as effectively as possible and to identify licensing opportunities. United States patents generally have a maximum term of 20 years from the date an application is filed. The Company has six United States patents and numerous foreign patents for the OraSure collection device and related technology, and has applied for additional patents, in both the United States and certain foreign countries, on such product and technology. The Company has one patent application pending for OraQuick HIV-1/2 in the United States and has obtained or is seeking licenses under existing patents held by third parties with respect to that product and technology. The Company may need to obtain licenses or other rights under, or enter into distribution or other business arrangements in connection with, certain HIV-2 and lateral flow patents, some of which have been obtained, in order to market the OraQuick HIV-1/2 test in the United States and certain other countries. See the Section entitled, "Risk Factors - Patent Issues Affecting OraQuick," for a further discussion of these issues. In April 1995, the Company received exclusive worldwide rights under patents and know-how owned by SRI International to develop and market products that involve the use of UPT. The Company also received non-exclusive worldwide rights under patents and know-how owned by the Sarnoff Corporation (formerly called the David Sarnoff Research Center) to develop and market products that involve the use of UPT. The Company has the right to sublicense these rights under the agreements subject to consent from SRI and Sarnoff. 12

Under the agreement with SRI, OraSure Technologies is required to make license, maintenance and royalty payments to SRI. The Company made an initial license payment to SRI in 1995 and paid research fees in 1995 and 1996 in connection with development projects in which SRI participated. The Company is obligated to make annual maintenance payments on each anniversary of the agreement following the completion of the development period until the first commercial sale of a product. The Company also must make royalty payments for a period equal to the longer of ten years from the date of the first commercial sale of the products or the term during which the manufacture, use, or sale of a product would infringe licensed patents, but for SRI's license to the Company. The Company believes that the royalty rates payable by the Company are comparable to the rates generally payable by other companies under similar arrangements. The Company's agreement with SRI terminates upon the expiration of the Company's obligation to pay royalties to SRI. In 1999, the Company paid $1.5 million to TPM Europe Holding B.V., its sublicensor (1) for the termination of an existing license agreement between the sublicensor and the Company with respect to the sublicense of UPT patents owned by Leiden University, The Netherlands, and (2) to secure a direct research, development, and license arrangement with Leiden University. The United States and European Patent Offices have issued licensors nine patents for methods, compositions, and apparatuses relating to phosphor technologies. Several additional UPT patent applications remain pending in the U.S. and abroad. The Company expects to continue to expand its UPT patent portfolio in 2001. The Company has one U.S. patent relating to the Company's method for detecting blood in urine specimens and the Company's AUTO-LYTE products. The Company has four U.S. patents and numerous foreign patents issued for apparatuses and methods for the topical removal of skin lesions relating to its Histofreezer device. The Company has five U.S. patents and numerous foreign patents and patent applications for the analog-to-digital threshold signaling technology used in the Q.E.D. test. These patents are related to the analog-to-digital technology color control systems and methods, systems and devices for the test, and detection of biochemical molecules. It is the Company's policy to require its employees, consultants, outside collaborators, and other advisors to execute confidentiality agreements upon the commencement of employment or consulting relationships with the Company. These agreements provide that all confidential information developed by or made known to the individual during the course of the individual's relationship with the Company, is to be kept confidential and not disclosed to third parties except in specific circumstances. In the case of employees, the agreements provide that all inventions conceived by the individual during his or her tenure at the Company will be the exclusive property of the Company. The Company owns rights to trademarks and service marks that it believes are necessary to conduct its business as currently operated. The Company is the owner in the United States of trademarks, including UPT(TM), UPlink(TM), OraSure(R), Intercept(TM), OraQuick(R), Histofreezer(R), Q.E.D.(R), and AUTO-LYTE(R). The Company also is the owner of many of these marks and others in several foreign countries. The Company is not aware of any pending claims of infringement or other challenges to the Company's rights to use its marks in the United States or in other countries as currently used by the Company. Although important, the issuance of a patent or existence of trademark or trade secret protection does not in itself ensure the Company's success. Competitors may be able to produce products competing with a patented Company product without infringing on the Company's patent rights. Issuance of a patent in one country generally does not prevent manufacture or sale of the patented product in other countries. The issuance of a patent to the Company or to a licensor is not conclusive as to validity or as to the enforceable scope of the patent. The validity or enforceability of a patent can be challenged by litigation after its issuance, and, if the outcome of such litigation is adverse to the owner of the patent, the owner's rights could be diminished or withdrawn. Trade secret protection does not prevent independent discovery and exploitation of the secret product or technique. 13

GOVERNMENT REGULATION General - ------- Most of the Company's existing and proposed diagnostic products are regulated by the FDA, certain state and local agencies, and comparable regulatory bodies in other countries. This regulation governs almost all aspects of development, production, and marketing, including product testing, authorizations to market, labeling, promotion, manufacturing, and recordkeeping. All of the Company's FDA-regulated products require some form of action by the FDA before they can be marketed in the United States, and, after clearance, the Company must continue to comply with other FDA requirements applicable to marketed products. Both before and after clearance, failure to comply with the FDA's requirements can lead to significant penalties. Domestic Regulation - ------------------- Most of the Company's diagnostic products are regulated as medical devices. The Western Blot HIV-1 confirmatory test is regulated as a biologic product. There are two review procedures by which medical devices can receive FDA clearance. Some products may qualify for clearance under a Section 510(k) procedure, in which the manufacturer provides a premarket notification that it intends to begin marketing the product, and shows that the product is substantially equivalent to another legally marketed product (i.e., that it has the same intended use and is as safe and effective as a legally marketed device and does not raise different questions of safety and effectiveness). In some cases, the submission must include data from human clinical studies. Marketing may commence when the FDA issues a clearance letter finding such substantial equivalence. Clearance under this procedure may be granted within 90 days, although in some cases as much as a year or more may be required. If the medical device does not qualify for the 510(k) procedure (either because it is not substantially equivalent to a legally marketed device or because it is a Class III device required by statute and the FDA's implementing regulations to have an approved application for premarket approval), the FDA must approve a premarket approval application ("PMA") before marketing can begin. PMAs must demonstrate, among other matters, that the medical device provides a reasonable assurance of safety and effectiveness. A PMA is typically a complex submission, including the results of preclinical and clinical studies. Preparing a PMA is a detailed and time-consuming process. Once a PMA has been submitted, the FDA's review may be lengthy, often requiring one year or more, and may include requests for additional data. Biologic products must be the subject of an approved biologics license application ("BLA") before they can be marketed. The FDA approval process for a biologic is similar to the PMA approval process, involving a demonstration of the product's safety and effectiveness based in part on both preclinical and clinical studies. Many of the insurance testing products are used for non-medical purposes and many of the drugs-of-abuse products sold to state crime labs are labeled for "forensic use only." The FDA does not currently regulate these products. Every company that manufactures biological products or medical devices distributed in the United States must comply with the FDA's Good Manufacturing Practices ("GMP") regulations (also known as the Quality System Regulations). These regulations govern the manufacturing process, including design, manufacture, testing, release, packaging, distribution, documentation, and purchasing. Compliance with GMPs is generally required before the FDA will approve a PMA or BLA, and these requirements also apply to marketed products. Companies are also subject to other post-market and general requirements, including compliance with restrictions imposed on marketed products, compliance with promotional standards, recordkeeping, and reporting of certain adverse reactions. The FDA regularly inspects companies to determine compliance with GMPs and other post-approval requirements. Failure to comply with statutory requirements and the FDA's regulations can lead to substantial penalties, including monetary penalties, injunctions, product recalls, seizure of products, and criminal prosecution. 14

In June 2000, the FDA issued observations of deficiencies following an inspection of OraSure Technologies' manufacturing facilities in Beaverton, Oregon, stating the FDA's view that some of the Company's products were not manufactured in compliance with GMP regulations. The FDA previously issued a warning letter in September 1998, and observations of deficiencies in January 1999 to the Company based on prior inspections of the Oregon facilities. The FDA has questioned the Company's compliance with GMP regulations in areas such as process validation, purchasing controls, complaint handling, and equipment controls at the Oregon facilities. The Company has undertaken a substantial review of its manufacturing and quality assurance, and has either already made changes or has changes in process, to satisfy the FDA's regulations with respect to its GMP compliance. These plans were communicated to the FDA in a written reply in September 2000. On October 20, 2000, the FDA sent a letter to the Company regarding the Serum Western Blot product voicing the agency's concern over the previously observed deficiencies and stating its intent to revoke the Company's license to manufacture this product if the problems were not corrected in sufficient time. The FDA acknowledged the receipt of the Company's written responses and found that those items which had been completed appeared to be adequate, but required the Company to submit a comprehensive report on corrective action plans and the schedule to address the remaining items. The Company submitted such a report in November 2000, and believes that it either has already implemented changes or has changes in process that will adequately address the FDA's concerns. Although production of the Serum Western Blot product line has been suspended, OraSure Technologies has recognized that the basic changes to the overall quality systems needed to remedy the FDA's observations would also assist in the quality for all of the Company's product lines, and therefore has devoted a considerable amount of time and resources to improving quality procedures throughout the Company. Even with the substantial efforts and the progress made to date, there is a risk that the FDA will not be satisfied by the Company's efforts. If the FDA is not satisfied, it could take action intended to force OraSure Technologies to stop manufacturing its Western Blot or other products until the FDA believes the Company is in compliance with GMP requirements. Also, although the FDA has recently granted the Company permission to obtain certificates needed for export of products, the FDA could refuse export permission in the future if the agency determines that the Company's progress toward GMP compliance is not sufficient. The Company has voluntarily recalled Q.E.D. tests on two occasions. In both instances, the Q.E.D. tests were recalled because the Company did not believe that the materials met its quality standards. Both recalls were conducted according to FDA guidelines. The FDA investigated the initial recall in December 1996 and did not take any action against the Company. The FDA investigated the second recall in March 1998 and issued a 483 Notice due to the Company's failure to confirm to the FDA that the corrective actions taken by the Company to remedy the deficiencies leading to the March 1998 recall had corrected the problems. The Company has confirmed with the FDA that its corrective actions addressed the issues that led to the recall. If violations of the applicable regulations are noted during future FDA inspections of the Company's manufacturing facility, or the manufacturing facilities of a contract manufacturer, the continued marketing of the Company's products may be adversely affected. International - ------------- The Company is also subject to regulations in foreign countries governing products, human clinical trials and marketing. Approval processes vary from country to country, and the length of time required for approval or to obtain other clearances may in some cases be longer than that required for U.S. governmental approvals. The extent of potentially adverse governmental regulation affecting the Company that might arise from future legislative or administrative action cannot be predicted. The Company will pursue approval only in those countries that have a significant market opportunity. The International Organization for Standardization ("ISO") is a worldwide federation of national standards bodies from some 130 countries, established in 1947. The mission of ISO is to promote the development of standardization and related activities in the world with a view to facilitating the international exchange of goods and services. ISO certification is evidenced by the CE mark and indicates that the Company's quality system has complied with standards applicable from initial product design and development through production and distribution. ISO certification is a prerequisite to obtaining a CE mark, which is required for distribution of medical devices in the European common markets. 15

In the first quarter of 1999, the Company received approval to use the CE mark for the OraSure and Intercept collection devices. In December 2000, the Company's Bethlehem facility received final certification for the European Medical Device Directive (93/42/EEC), ISO 9001, ISO 13485, and EN46001. The Company also received authorization to use the CE mark for its Histofreezer product line. The Company must also submit evidence of marketing clearance by the FDA to Health Canada's Therapeutic Products Programme prior to commencing sales in Canada. The Company has completed this process for several of its current products which require FDA review. Environmental Regulation - ------------------------ Because of the nature of its current and proposed research, development, and manufacturing processes, the Company is subject to stringent federal, state, and local laws, rules, regulations, and policies governing the use, generation, manufacture, storage, air emission, effluent discharge, and handling and disposal of materials and wastes. The Company believes that it has complied with these laws and regulations in all material respects and has not been required to take any action to correct any noncompliance.

These and other factors that could cause the forward-looking statements to be materially different are described in greater detail in the Section entitled, "Risk Factors," and elsewhere in this Report. Although forward-looking statements help to provide complete information about future prospects, they may not be reliable. The forward-looking statements are made as of the date of this Report and Orasure Technologies undertakes no duty to update these statements. RISK FACTORS The following is a discussion of certain significant risk factors that could potentially affect the Company's financial condition, performance and prospects. Competing Products - ------------------ The diagnostic industry is focused on the testing of biological specimens in a laboratory or at the point-of-care and is highly competitive and rapidly changing. The Company's principal competitors have considerably greater financial, 16

technical, and marketing resources. As new products enter the market, the Company's products may become obsolete or a competitor's products may be more effective or more effectively marketed and sold than the Company's. If OraSure Technologies fails to maintain and enhance its competitive position, its customers may decide to use products developed by competitors which could result in a loss of revenues. Ability to Develop New Products - ------------------------------- In order to remain competitive, the Company must commit substantial resources each year to research and development. The research and development process generally takes a significant amount of time from inception to commercial product launch. This process is conducted in various stages, and during each stage there is a substantial risk that the Company will not achieve its goals and will have to abandon a product in which it has invested substantial amounts. The Company expects to continue to incur significant costs in its research and development activities. Moreover, there can be no assurance that OraSure Technologies will succeed in its research and development efforts. If the Company fails to develop commercially successful products, or if competitors develop more effective products or a greater number of successful new products, customers may decide to use products developed by the Company's competitors, which would result in a loss of revenues. Market Acceptance of Oral Fluid Testing Products - ------------------------------------------------ The Company has made significant progress in gaining acceptance of oral fluid testing for HIV in the insurance and public health markets. The Company also expects that oral fluid testing for drugs of abuse will be accepted in the workplace and criminal justice testing markets. Other markets, particularly the physician office market, may resist the adoption of oral fluid testing as a replacement for other testing methods in use today. There can be no assurance that the Company will be able to expand use of its oral fluid testing products in these or other markets. Loss or Impairment of Sources of Capital - ---------------------------------------- Although the Company has made significant progress in the past toward controlling expenses and increasing product revenue, the Company has historically depended to a substantial degree on capital raised through the sale of equity securities to fund its operations. The Company's future liquidity and capital requirements will depend on numerous factors, including the costs and timing of the expansion of manufacturing capacity, the success of product development efforts, the costs and timing of expansion of sales and marketing activities, the extent to which existing and new products gain market acceptance, competing technological and market developments, and the scope and timing of strategic acquisitions. If additional financing is needed, the Company may seek to raise funds through the sale of equity securities. There can be no assurance that financing through the sale of equity securities, or otherwise, will be available on satisfactory terms, if at all. Ability of the Company to Develop Product Distribution Channels - --------------------------------------------------------------- The Company has marketed many of its products by collaborating with diagnostic companies and distributors. For example, the Company's OraSure Western Blot confirmatory tests are distributed through Organon Teknika, and the OraSure collection device is distributed to the insurance industry through major insurance testing laboratories. The Company's sales depend to a substantial degree on its ability to develop product distribution channels and on the marketing abilities of the companies with which it collaborates. There can be no assurance that such companies will continue to be able to distribute the Company's products or that new distribution channels will be available on satisfactory terms. Ability to Obtain and Timing of Regulatory Approvals - ---------------------------------------------------- The Company is subject to strict government controls on the development, manufacture, labeling, distribution and marketing of its products. The Company often must obtain and maintain regulatory approval for a product from a country's national health or drug regulatory agency before the product may be sold in a particular country. The submission of an application to a regulatory authority does not guarantee that it will grant a license to market the product. Each authority may impose its own requirements and delay or refuse to grant approval, even though a product has been approved in another country. 17

In the Company's principal markets, the approval process for a new product can be complex and lengthy. The time taken to obtain approval varies depending on the nature of the application and may result in the passage of a significant period of time from the date of application. This increases the cost of developing new products and increases the risk that the Company will not succeed in introducing or selling them. In addition, the European Union has established a requirement that diagnostic medical devices used to test biological specimens must receive regulatory approval known as a CE mark by December 2003. After that date, export to the European community of products without the CE mark will be stopped or delayed until the mark is received. This requirement will affect many of OraSure Technologies' products. OraSure Technologies will not be permitted to make European sales of its products for which a CE mark is not obtained by December 2003, which could lead to the termination of strategic alliances for sales of those products in Europe. While the Company intends to apply for CE marks for certain of its existing and future products, and is not aware of any material reason why such approvals will not be granted, there can be no assurance that a CE mark will be received prior to the deadline. Regulatory Compliance - --------------------- The Company can manufacture and sell many of its products, both in the United States and in some cases abroad, only if it complies with regulations of government agencies such as the FDA. The Company has implemented quality assurance and other systems that are intended to comply with applicable regulations. The FDA has issued warning letters and a letter of intent to revoke the Company's license with respect to the Serum Western Blot product, stating that the Company is not in compliance with the FDA's regulations. The Company has responded to each of these letters. Although the Company believes that it has satisfactorily addressed the points raised by the FDA, the FDA could force the Company to stop manufacturing products if the FDA concludes that the Company remains out of compliance with applicable regulations. In addition, until the FDA agrees that the Company has resolved all points raised in the letters, the Company may not be able to obtain regulatory clearance certificates needed in certain foreign countries. See the Section entitled "Government Regulation" for a further discussion of regulatory compliance matters. Changes in Federal or State Law or Regulations - ---------------------------------------------- As described more fully above under "Government Regulation," many of the Company's proposed and existing products are subject to regulation by the FDA and other governmental agencies. The process of obtaining required approvals from these agencies varies according to the nature of and uses for the product and can involve lengthy and detailed laboratory and clinical testing, sampling activities, and other costly and time-consuming procedures. Changes in government regulations could require the Company to undergo additional trials or procedures, or could make it impractical or impossible for the Company to market its products for certain uses, in certain markets, or at all. Other changes in government regulations, such as the adoption of the FDA's Quality System Regulation, may not affect the Company's products directly but may nonetheless adversely affect the Company's financial condition and results of operations by requiring that the Company incur the expense of changing or implementing new manufacturing and control procedures. Ability to Market New Products - ------------------------------ OraSure Technologies' future success will depend partly on the market acceptance, and the timing of such acceptance, of recently introduced products such as the Intercept oral fluid drug test service, the OraQuick rapid oral fluid test, products currently under development such as UPlink and other products using up-converting phosphor technology, and other new products or technologies that may be developed or acquired and introduced in the future. To achieve market acceptance, OraSure Technologies must make substantial marketing efforts and spend significant funds to inform potential customers and the public of the perceived benefits of these products. The Company currently has limited evidence on which to evaluate the market reaction to products that may be developed, and there can be no assurance that any products will meet with market acceptance and fill the market need that is perceived to exist. 18

Reliance on Patents and Other Proprietary Rights - ------------------------------------------------ The diagnostics industry places considerable importance on obtaining patent, trademark, and trade secret protection, as well as other intellectual property rights, for new technologies, products and processes. The Company's success depends, in part, on its ability to develop and maintain a strong intellectual property portfolio for products and technologies both in the United States and in other countries. Litigation or other legal proceedings may be necessary to defend against claims of infringement or to enforce intellectual property rights, and could result in substantial costs and diversion of resources. As appropriate, the Company intends to file patent applications and obtain patent protection for its proprietary technology. These patent applications and patents will cover, as appropriate, compositions of matter for the Company's products, methods of making those products, methods of using those products, and apparatus relating to the use or manufacture of those products. The Company will also rely on trade secrets, know-how and continuing technological advancements to protect its proprietary technology. The Company has entered, and will continue to enter, into confidentiality agreements with its employees, consultants, advisors and collaborators. However, these parties may not honor these agreements and the Company may not be able to successfully protect its rights to unpatented trade secrets and know-how. Others may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to the Company's trade secrets and know-how. Many of the Company's scientific and management personnel were previously employed by competing companies. Although the Company encourages and expects all of these types of employees to abide by any confidentiality agreement with a prior employer, competing companies may allege trade secret violations and similar claims against OraSure Technologies. To facilitate development and commercialization of a proprietary technology base, the Company may need to obtain licenses to patents or other proprietary rights from other parties. If the Company is unable to obtain these types of licenses, the Company's product development and commercialization efforts may be delayed. The Company may collaborate with universities and governmental research organizations which, as a result, may acquire part of the rights to any inventions or technical information derived from collaboration with them. The Company may incur substantial costs in asserting or protecting its intellectual property rights, or in defending suits against it related to intellectual property rights. Disputes regarding intellectual property rights could substantially delay product development or commercialization activities. Disputes regarding intellectual property rights might include state or federal court litigation as well as patent interference, patent reexamination, patent reissue, or trademark opposition proceedings in the United States Patent and Trademark Office. Opposition or revocation proceedings could be instituted in a foreign patent office. An adverse decision in any proceeding regarding intellectual property rights could result in the loss of the Company's rights to a patent, an invention, or trademark. Patent Issues Affecting OraQuick - -------------------------------- There are factors that will affect the specific countries in which the Company will be able to sell its OraQuick rapid HIV-1/2 test and therefore the overall sales potential of the test. One factor is whether the company can arrange a sublicense or distribution agreement related to patents for detection of the HIV-2 virus. HIV-2 is a type of the HIV virus estimated to represent less than 2% of known HIV cases worldwide. Nevertheless, HIV-2 is considered to be an important component in the testing regimen for HIV in many markets. HIV-2 patents are in force in most of the countries of North America and Western Europe, as well as in Japan, Korea, South Africa and Australia. Access to a license for one or more HIV-2 patents may be necessary to sell HIV-2 tests in countries where such patents are in force, or to manufacture in countries where such patents are in force and then sell into non-patent markets. Since HIV-2 patents are in force in the United States, the Company may be restricted from manufacturing its OraQuick rapid HIV test in the United States and selling into other countries, even if there were no HIV-2 patents in those other countries. 19

The importance of HIV-2 differs by country, and can be affected by both regulatory requirements and by competitive pressures. In most countries, any product used to screen the blood supply will require the ability to detect HIV-2, although the OraQuick rapid HIV test has not been intended for that market purpose. In other markets, including the United States, a test that can detect only the more prevalent HIV-1 type is generally considered sufficient, except in testing related to blood supply. Because the competitive situation in each country will be affected by the availability of other testing products as well as the country's regulatory environment, the Company may be at a competitive disadvantage in some markets without an HIV-2 product even if HIV-2 detection is not required by regulations. Another factor that may affect the specific countries in which the Company will be able to sell its OraQuick rapid HIV test, and therefore the overall sales potential, concerns whether the Company can arrange a sublicense or distribution agreement related to any patents which claim lateral flow assay methods and devices covering the OraQuick rapid HIV test or its use. The OraQuick rapid HIV test is an analyte-specific lateral flow assay device. There are numerous patents in the United States and other countries which claim lateral flow assay methods and devices that are analyte independent. Some of these patents broadly cover the technology used in the OraQuick assay and are in force in the United States and other countries. The Company would also not be able to make the OraQuick rapid HIV test in the United States and sell it in countries where there is no patent on the device. The Company has licenses under several lateral flow patents and is considering the need for licenses under others. In the event that it is not possible to negotiate a license agreement under a necessary patent, the Company may be able to modify the OraQuick rapid HIV test such that a license would not be necessary. However, this alternative could delay introduction of the OraQuick rapid HIV test into the U.S. and other markets. History of Losses and Projected Profitability - --------------------------------------------- The Company has not achieved profitability, but expects to be profitable during the second half of 2001 and for the year 2001. The Company incurred net losses of approximately $12.7 million and $4.2 million in 2000 and 1999, respectively, and as of December 31, 2000, the Company had an accumulated deficit of approximately $122.4 million. The Company's limited combined operating history makes it difficult to forecast future operating results. In order to achieve profitability in the estimated time period, the Company's revenue will have to continue to grow at the estimated rates. The Company's ability to reach its estimated revenue growth will be dependent upon a number of factors, including without limitation achieving growth in international markets through the Company's OraQuick rapid HIV test, creating market acceptance for the Intercept drugs of abuse products, and commercially developing, obtaining regulatory approval, and creating market acceptance for UPT and other products in a time frame consistent with the Company's objectives. The Company has not yet fully achieved these objectives. In the event that the Company cannot create a significant commercial market for its OraQuick test, the Intercept and UPT products or its other products, or to the extent other events described in this Section entitled "Risk Factors" occur, the Company's revenue, and consequently profitability, could be lower than estimated. Loss of Key Personnel - --------------------- The Company's success will depend to a large extent upon the contributions of its executive officers, management, and scientific staff. The Company may not be able to attract or retain qualified employees in the future due to the intense competition for qualified personnel among other medical products businesses. If the Company is not able to attract and retain the necessary personnel to accomplish its business objectives, the Company may experience constraints that will adversely affect its ability to meet the demands of its strategic partners in a timely fashion or to support internal research and development programs. In particular, product development programs depend on the ability to attract and retain highly skilled scientists, including molecular geologists, biochemists and engineers. Recruiting qualified personnel can be an intensely competitive and time-consuming process. Although OraSure Technologies believes it will be successful in attracting and retaining qualified personnel, competition for experienced scientists and other technical personnel from numerous companies and academic and other research institutions may limit its ability to do so on acceptable terms. All of the Company's employees, other than a few senior officers who have employment agreements, are at-will employees, which means that either the employee or OraSure Technologies may terminate their employment at any time. If the Company experiences difficulty in recruiting and retaining qualified personnel, and in particular scientific personnel, it may need to provide higher 20

compensation to such personnel than currently anticipated or the Company may incur additional expenses for the recruitment of qualified personnel. The Company's business plans will require additional expertise in specific industries and areas applicable to the development efforts related to up-converting phosphor technologies. These activities will require the addition of new personnel, including management, and the development of additional expertise by existing management personnel. The inability to acquire these services or to develop this expertise could impair the development, if any, of products related to these technologies. International Marketing and Manufacturing - ----------------------------------------- The Company intends to devote significant resources to increase international sales of its OraQuick and UPT products. However, in the past, it has not had significant direct experience with the governmental regulatory agencies in foreign countries that control sale of products into those countries. In addition to economic and political issues, a number of factors can slow or prevent international sales, or substantially increase the cost of international sales, including those set forth below: o Regulatory requirements may slow, limit, or prevent the offering of products in foreign jurisdictions; o Cultural and political differences may make it difficult to effectively market, sell and gain acceptance of products in foreign jurisdictions; o Inexperience in international markets may slow or limit the Company's ability to sell products in foreign countries; o Exchange rates, currency fluctuations, tariffs and other barriers, extended payment terms and dependence on and difficulties in managing international distributors or representatives may affect the Company's revenues even when product sales occur; o The creditworthiness of foreign entities may be less certain and accounts receivable collection may be more difficult; The Company recently entered into a contract for the manufacture and supply of the OraQuick HIV-1/2 device in Thailand. However, the Company does not have significant direct experience with the use of international manufacturers. Factors such as economic and political conditions and foreign regulatory requirements may slow or prevent the manufacture of the Company's products in countries other than the United States Interruption of the supply of the Company's products could reduce revenues or cause the Company to incur significant additional expenses in finding an alternative source of supply. Product Liability Exposure - -------------------------- The Company may be held liable if any of its products, or any product which is made with the use or incorporation of any of the technologies belonging to the Company, causes injury of any type or is found otherwise unsuitable during product testing, manufacturing, marketing or sale. Although the Company has obtained product liability insurance, this insurance may not fully cover potential liabilities. As new products come to market, the Company may need to increase its product liability coverage. Inability to obtain sufficient insurance coverage at an acceptable cost or otherwise to protect against potential product liability claims could affect the Company's decision to commercialize products developed by OraSure Technologies or its strategic partners. If the Company is sued for any injury caused by its products, its liability could exceed its total assets. Ability to Commercialize UPT - ---------------------------- The Company's up-converting phosphor technology is new and is in the early stage of development. Commercial development of UPT may not be successful. Successful products require significant development and investment, 21

including testing, to demonstrate their cost-effectiveness or other benefits prior to their commercialization. In addition, regulatory approval must be obtained before most products based upon UPT may be sold. Additional development efforts on these products will be required before any regulatory authority will review them. Regulatory authorities may not approve these products for commercial sale. Accordingly, because of these uncertainties, products based upon UPT may not be commercialized. The failure to develop UPT products with commercial potential would negatively affect OraSure Technologies' future revenues. Dependence on Strategic Partners - -------------------------------- Although the Company intends to pursue some product opportunities independently, opportunities that require a level of investment for development and commercialization may necessitate involving one or more strategic partners. In particular, the Company's strategy for development and commercialization of UPT and certain other products may entail entering into additional arrangements with corporate partners, universities, research laboratory licensees, and others. If OraSure Technologies is not able to enter into such arrangements, the Company may be required to transfer material rights to such strategic partners, licensees, and others. While the Company expects that its current and future partners, licensees, and others have and will have an economic motivation to succeed in performing their contractual responsibilities, the amount and timing of resources to be devoted to these activities will be controlled by others. Consequently, there can be no assurance that any revenues or profits will be derived from such arrangements. Dependence on Third Party Licenses and Rights - --------------------------------------------- The Company has licensed the worldwide rights to up-converting phosphor compositions, methods, and apparatuses for use in diagnostic applications, which are the subject of seven issued United States patents, and of one pending U.S. patent application. Corresponding patents and patent applications have been granted or issued in numerous foreign countries, including, for example, European countries, Japan, and Canada. OraSure Technologies cooperates with the licensor to prosecute such patent applications and protect such patent rights. Failure by the licensor to prosecute such applications and protect such patent rights could harm the Company's business. If the licensors do not meet their obligations under the license agreements or do not reasonably consent to sublicenses by the Company, or if the license agreement is terminated, the Company could lose the opportunity to develop UPT. The previous discussion of the Company's business should be read in conjunction with the Financial Statements and accompanying notes included in Item 14 of this Annual Report on Form 10-K. ITEM 2. PROPERTIES. On April 30, 1999, the Company signed a five-year lease to rent 25,845 square feet of space at the John M. Cook Technology Center on the south side of Bethlehem, Pennsylvania located at 150 Webster Street, which the Company uses as its main corporate, sales and marketing, and research and development offices. Annual rent for the first five years of this lease is approximately $270,000. The lease also includes a five-year renewal option and a ten-year purchase option. The Company owns 33,500 square feet on 3.4 acres of land at 1745 Eaton Avenue in Bethlehem, Pennsylvania which is used for manufacturing, engineering, information systems and accounting activities. The Company rents additional warehouse space on an as-needed basis. The Company leases space for a sales office in Reeuwijk, The Netherlands. The Company leases approximately 30,500 square feet of office, manufacturing, and laboratory space in Beaverton, Oregon, under a lease that expires on January 31, 2005. The Company has base lease obligations under the lease, which escalate during the term of the lease and average approximately $375,000 per year. The Company also leases 2,265 square feet of warehouse space in Oregon to store inventory and equipment under a lease expiring September 30, 2002. The Company believes that its existing facilities are adequate for its current requirements. 22

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. Statements below regarding future events or performance are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. The Company's actual results could be quite different from those expressed or implied by the forward-looking statements. Factors that could affect results are discussed more fully under the Sections entitled "Forward-Looking Statements" and "Risk Factors" in Item 1 and elsewhere in this Annual Report on Form 10-K. Although forward-looking statements help to provide complete information about the Company, readers should keep in mind that forward-looking statements may not be reliable. Readers are cautioned not to place undue reliance on the forward-looking statements. RESULTS OF OPERATIONS - 2000 COMPARED TO 1999 On September 29, 2000, STC Technologies, Inc. ("STC"), a privately held company, and Epitope, Inc. ("Epitope"), a public company whose stock was traded on the Nasdaq Stock Market, were merged into the Company (the "Merger"). The Merger was structured as an all stock transaction valued at $260 million and was accounted for as a "pooling of interests." The Company is reporting its financial results for 2000 on a calendar year basis. Epitope previously reported its financial results on the basis of a fiscal year ending September 30, while STC previously reported its financial results on a calendar year basis. Immediately prior to the Merger, Epitope adopted a fiscal year ending December 31 for financial reporting purposes beginning in 2000. As a result, the Financial Data for 1999 reflects results for the twelve-month periods ended September 30, 1999 and December 31, 1999 for Epitope and STC, respectively. See Note 1 to the Company's Financial Statements for a discussion of the Merger and the change in fiscal year end. The Merger is expected to leverage the Company's expertise in oral fluid technology, infectious disease testing and substance abuse testing. By building upon the complementary product portfolios, technologies and sales infrastructures of Epitope and STC, the Company intends to open up new markets in the United States and other countries and strengthen its position in key markets such as the rapidly expanding point-of-care market. In particular, the proprietary up-converting phosphor technology contributed by STC has broad applications for oral fluid testing. With the increased sensitivity and accuracy of this technology, the Company believes it can continue to expand the menu of tests available for oral fluid point-of-care testing. This same basic technology is also expected to be of significant benefit to other medical diagnostic manufacturers outside the expertise contributed by Epitope and STC. For many of these additional applications, OraSure Technologies plans to license these other companies to provide an ongoing revenue stream of license fees and royalties. 25

Sales of the oral specimen collection devices increased approximately 44% to $11.2 million as a result of higher 26

penetration in the life insurance and public health markets. Sales of the Histofreezer product increased approximately 18% to $6.8 million principally as a result of price and volume increases both domestically and internationally. Immunoassay test sales increased approximately 9% to $6.7 million as a result of increased activity in the life insurance testing market. Sales of the Western Blot products declined 11% to $1.9 million as a result of an overall decline in demand and increased price competition. The Intercept product, which was launched in February 2000, and OraQuick, which began shipping in December 2000, generated approximately $300,000 and $80,000 of revenue, respectively, in 2000. As a percentage of product revenues, international product sales increased to approximately 14% in 2000 from 12% in 1999 as a result of increased international sales of the Histofreezer product and the OraSure collection devices. The table below shows the amount (in thousands) and percentage of the Company's total revenue contributed by each of its principal markets and by license and product development activities. Percentage of Dollars Total Revenues (%) ----------------- ------------------- Percent 2000 1999 Change (%) 2000 1999 ------- ------- ---------- --------- --------- Market sales Insurance testing $12,742 $11,177 14 44 46 Public health 4,705 2,914 61 16 12 Physician offices 6,780 5,744 18 24 24 Substance abuse testing 3,179 2,527 26 11 11 Other markets 689 786 (12) 3 3 ------- ------- --------- --------- 28,095 23,148 21 98 96 License and product development 693 898 (23) 2 4 ------- ------- --------- --------- Total revenues $28,788 $24,046 20 100 100 ======= ======= ========= ========= Sales to the insurance testing market increased by 14% to approximately $12.7 million in 2000 as a result of increased market acceptance of the oral specimen collection device and higher sales of the associated immunoassay tests. Sales to the public health market increased 61% to approximately $4.7 million in 2000 as a result of increased penetration of the Company's higher priced public health HIV kit. Sales to physician offices, which consist solely of the Histofreezer cryosurgical system, increased 18% to approximately $6.8 million in 2000 as a result of price and volume increases both domestically and internationally. Sales to the substance abuse testing market increased 26% to approximately $3.2 million in 2000 as a result of the market introduction of Intercept and increased Q.E.D. and forensic toxicology sales. License and product development revenue decreased 23% to approximately $693,000 in 2000 from approximately $898,000 in 1999. During 2000, license and product development revenue primarily consisted of income from a collaboration with LabOne, Inc. related to the Intercept drugs-of-abuse service, a research agreement with Drager to develop specific target analytes for UPlink point-of-care drugs-of-abuse testing, and the first phase of a grant from the National Institutes of Health ("NIH") for the development of an oral fluid, laboratory-based test for syphilis using the OraSure collection device. During 1999, the Company received license and product development revenue in connection with a research agreement to collaborate on the development of analytes for point-of-care testing, a business and technology assessment of UPT for food pathogen applications, and the Company's collaboration with LabOne for the Intercept service. During 2001, the Company plans to focus its efforts on the development of license and product development revenue from external research and development contracts. As of December 31, 2000, the Company was performing paid research and development for Drager, Meridian Bioscience, LabOne, and the NIH. In addition, the Company will continue to attempt to develop new relationships with third parties that are expected to generate revenue streams for the Company through research and development and supply agreements. There can be no assurance as to the Company's ability to enter into these types of arrangements or the timing of additional revenues, if any. 27

Total revenue is expected to increase by 50% to approximately $43 million in 2001, as a result of the expansion of OraQuick HIV-1/2 product sales in international markets, the launch of the first UPlink products in the second half of 2001, and the continued growth of other product lines. Partially offsetting this sales growth will be the elimination of $1.4 million of annual revenue associated with the suspended Serum Western Blot product line. In February 2001, the Company announced the indefinite suspension of its Serum Western Blot product. This product has historically been unprofitable due to low production yields and the high cost of ensuring the quality of the end product. The Company's ability to achieve the expected level of revenue will depend on a number of factors, including, but limited to, its ability to scale up manufacturing of OraQuick HIV-1/2, complete development of its UPlink products, and establish distribution channels for these and other products and obtain all required regulatory approvals and clearances (including completing any required clinical trials) in the United States and in other countries. The Company's gross margin declined slightly to 61% in 2000 from 62% in 1999. The decline is the result of the Company expensing approximately $1.1 million of obsolete inventory, the suspension of the Serum Western Blot product line and manufacturing inefficiencies related to the start up of the OraQuick product line. Without these items, gross margin would have been 65% for the year 2000. Partially offsetting the gross margin reductions in 2000 were favorable changes in product mix and greater revenues compared to the Company's fixed costs. In February 2001, the Company announced its plans to realign its manufacturing operations, which will include the elimination of the manufacturing of OraQuick in the Beaverton, Oregon facility, the installation of automated manufacturing equipment for OraQuick in Bethlehem, Pennsylvania, and the addition of manufacturing capacity in Thailand. This action will provide greatly expanded capacity for production of OraQuick and is expected to result in approximately $1.5 million in annual cost savings to the Company beginning in 2002. Gross margins are anticipated to improve beginning in 2001 as a result of (1) the consolidation of manufacturing operations in Bethlehem, Pennsylvania, (2) Merger-related efficiencies, and (3) the suspension of the unprofitable Serum Western Blot product line. Research and development expenses increased 86% to approximately $10.4 million in 2000 from approximately $5.6 million in 1999. Research and development efforts in 2000 were focused on the development of the OraQuick HIV-1/2 rapid test, development of the UPlink reader, test cassette and collector for drugs-of-abuse applications, DNA feasibility studies, and regulatory compliance. In addition, the Company also performed research and development activities with respect to additional Intercept products, new antibody development, and improvements to existing products. Research and development expenses are expected to increase as clinical trials for OraQuick HIV-1/2 and UPlink research activities continue. In an effort to meet the aggressive development schedule for OraQuick and UPlink, the Company continues to hire additional personnel and has contracted with several outside consulting firms to supplement the Company's internal resources. The Company expects expenses related to the development of UPlink to increase over historical levels. Sales and marketing expenses increased approximately 22% to approximately $6.9 million from approximately $5.7 million in 1999. This increase was primarily the result of costs to develop and establish foreign markets for OraQuick, which was launched at the XIII International AIDS Conference in Durban, South Africa in July 2000, costs associated with the national market launch of the Intercept drugs-of-abuse service that began in February 2000, and expanded sales activities for the Company's other product lines. Despite the increase in spending, sales and marketing expenses, as a percentage of 2000 revenues, remained constant at 24%. In connection with the continued expansion of sales and marketing activities for the Company's new products, the Company anticipates an increase in its marketing and sales efforts to create market awareness and demand for these new products. In addition, the Company will focus its efforts on business plan development, market research, and staffing additions for the expected launch of the first UPlink products in 2001. In 1999, the Company paid $1.5 million to TPM Europe Holding B.V., its sublicensor (1) for the termination of an existing license agreement between the sublicensor and the Company with respect to the sublicense of UPT patents 28

owned by Leiden University, The Netherlands, and (2) to secure a direct research, development, and license arrangement with Leiden University. There were no such expenses in 2000. See "Results of Operations - 1999 Compared to 1998." General and administrative expenses increased 10% to approximately $6.9 million in 2000 from approximately $6.2 million in 1999. This increase was the result of increased staffing levels and operating expenses associated with the facility expansion in Pennsylvania. Despite the increase of spending, general and administrative expenses, as a percentage of 2000 revenues, declined to 24% from 26%. General and administrative expenses are expected to decline slightly in 2001 as the Company begins to achieve its Merger cost savings as a result of the consolidation of the Accounting, Financing, and Human Resources departments and the continued elimination of duplicative overhead structures. The Company anticipates that the total overhead cost savings will exceed approximately $1 million per year. The Company anticipates additional non-recurring costs resulting from the realignment of manufacturing operations to be approximately $400,000 in the first quarter of 2001. Merger-related expenses were approximately $7.6 million in 2000. These costs included fees for investment bankers, attorneys and accountants, filing and soliciting proxies, employee severance, and integration costs. Operating loss increased to approximately $14.1 million in 2000 from approximately $4.1 million in 1999 as a result of expenses associated with the Merger, increased research and development costs, and increased sales and marketing costs. Excluding the non-recurring Merger related expenses, the operating loss would have been approximately $6.5 million. Interest expense decreased to approximately $491,000 in 2000 from approximately $545,000 in 1999 as a result of principal loan repayments and the refinancing of subordinated debt. Interest expense is expected to decrease in 2001 as a result of the continued repayment of term debt, coupled with the use of cash reserves and internally generated funds for future capital purchases. Interest income increased to approximately $1.3 million in 2000 from approximately $595,000 in 1999 as a result of higher cash and cash equivalents available for investment as a result of the exercise of stock options and warrants. Interest income is expected to increase slightly in 2001 as a result of higher average cash balances. Foreign currency loss was approximately $19,000 in 2000 compared to a loss of approximately $141,000 in 1999. Foreign currency fluctuations are not expected to have a material impact in 2001. Gain on the sale of securities was $600,000 in 2000 as a result of a gain on the sale of A&W Preferred Stock the Company had received as a part of a settlement with A&W in 1997. There was no similar item in 1999. During 2000, a provision for income taxes of approximately $24,000 was recorded. Net loss was approximately $12.7 million in 2000 compared to approximately $4.2 million in 1999. Excluding the non-recurring Merger-related expenses, the net loss would have been approximately $5.1 million. RESULTS OF OPERATIONS - 1999 COMPARED TO 1998 As a result of the Merger between Epitope and STC on September 29, 2000 and the subsequent change in the Company's fiscal year-end from September 30 to December 31, the Financial Data for 1999 reflects results for the twelve-month periods ended September 30, 1999 and December 31, 1999 for Epitope and STC, respectively, on a consolidated basis. The Financial Data for 1998 reflects results for the twelve-month periods ended September 30, 1998 and December 31, 1998 for Epitope and STC, respectively, on a consolidated basis. See Note 1 to the Company's Financial Statements for a discussion of the Merger and the change in fiscal year end. 29

The table below shows the amount (in thousands) and percentage of the Company's total revenue contributed by each of its principal products and by license and product development activities. Percentage of Dollars Total Revenue (%) ------------------- ------------------- Percent 1999 1998 Change(%) 1999 1998 -------- -------- ----------- ------- ------- Product revenue Oral specimen collection devices $ 7,806 $ 7,195 8 32 36 OraQuick - - - - - Histofreezer cryosurgical systems 5,744 4,776 20 24 23 Immunoassay tests 6,158 4,804 28 26 23 Western Blot HIV confirmatory tests 2,133 2,370 (10) 9 12 Other product revenue 1,307 1,101 19 5 5 -------- -------- ------- ------- 23,148 20,246 14 96 99 License and product development 898 198 354 4 1 -------- -------- ------- ------- Total revenues $ 24,046 $ 20,444 18 100 100 ======== ======== ======= ======= Product revenue increased 14% to approximately $23.1 million in 1999 from approximately $20.2 million in 1998. This increase was the result of sales of immunoassay tests, which grew 28% to approximately $6.2 million primarily as a result of increased insurance activity, and sales of Histofreezer, which increased 20% to approximately $5.7 million largely due to the acquisition of the worldwide Histofreezer product line in June 1998. Sales of the oral specimen collection devices increased 8% to approximately $7.8 million as a result of higher penetration in the life insurance and public health markets. Sales of the Western Blot product declined 10% to $2.1 million as a result of increasing competition. As a percentage of product revenue, international sales decreased to 12% in 1999 from 13% in 1998. The table below shows the amount (in thousands) and percentage of the Company's total revenue contributed by each of its principal markets and by license and product development activities. Percentage of Dollars Total Revenues (%) ------------------ ------------------- Percent 1999 1998 Change (%) 1999 1998 ------- -------- ---------- --------- --------- Market sales Insurance testing $11,177 $ 9,311 20 46 46 Public health 2,914 2,944 (1) 12 14 Physician offices 5,744 4,776 20 24 23 Substance abuse testing 2,527 2,114 20 11 10 Other markets 786 1,101 (29) 3 6 ------- -------- --------- --------- 23,148 20,246 14 96 99 License and product development 898 198 354 4 1 ------- -------- --------- --------- Total revenues $24,046 $ 20,444 18 100 100 ======= ======== ========= ========= Sales to the insurance testing market increased by 20% to approximately $11.2 million in 1999 as a result of increased market acceptance of the oral specimen collection device, increased testing volume of both urine and oral fluid products, and price increases. Sales to the public health market remained flat at approximately $2.9 million in 1999. Sales to physician offices, which consisted solely of the Histofreezer cryosurgical system, increased 20% to approximately $6.8 million in 1999 as a result of the Histofreezer acquisition in June, 1998. Sales to the substance 31

abuse testing market increased 20% to approximately $2.5 million in 1999 as a result of increased Q.E.D. and forensic toxicology sales. Licensing and product development revenues increased 354% to approximately $898,000 in 1999 from approximately $198,000 in 1998. This increase was primarily the result of the Company beginning to secure research projects for the evaluation of UPT for a range of market applications. During 1999, the Company received licensing and product development revenues from a research agreement to collaborate on the development of analytes for point-of-care testing, a business and technology assessment of UPT for food pathogen applications, and the Company's partnership with LabOne for the Intercept service. During 1998, licensing and product development revenues consisted primarily of fees from outside parties to develop proprietary antibodies and revenues for the development of the Q.E.D. alcohol test. The Company's gross margin increased to 62% in 1999 from 59% in 1998 primarily as a result of increased sales of high margin reagents and Histofreezer products and improved manufacturing operating processes, partially offset by a decline in gross margins of the Western Blot products. Research and development expenses increased 25% to approximately $5.6 million in 1999 from approximately $4.5 million in 1998. Research and development efforts were focused on the development of the OraQuick HIV rapid test, UPT development, commercialization of the Intercept service, and FDA regulatory compliance. UPT efforts were focused on the development of a lateral flow device, particle size reduction, feasibility studies for on-site drugs-of-abuse and food borne pathogens testing, and development of the UPlink reader. Sales and marketing expenses increased 22% to approximately $5.7 million in 1999 from approximately $4.7 million in 1998. This increase was primarily a result of the Company's preparation for the national market launch of the Intercept drugs-of-abuse service in February 2000, establishment of an international sales office in The Netherlands, and expanded sales activities for existing product lines. In 1999, the Company paid $1.5 million to TPM Europe Holding B.V., its sublicensor (1) for the termination of an existing license agreement between the sublicensor and the Company with respect to the sublicense of UPT patents owned by Leiden University, The Netherlands, and (2) to secure a direct research, development, and license arrangement with Leiden University. The Company accounted for the purchase price as acquired in-process technology expense because, at the date of the transaction, the technology rights acquired by the Company related to UPT had not progressed to a stage where it met technological feasibility and there existed a significant amount of uncertainty as to the Company's ability to complete the development of the technology which would achieve market acceptance within a reasonable timeframe. In addition, the acquired in-process technology did not have an alternative future use to the Company that had reached technological feasibility. There were no such expenses in 1998. General and administrative expenses increased 21% to approximately $6.2 million in 1999 from approximately $5.2 million in 1998, as a result of the amortization of the patent and product rights associated with the acquisition of worldwide distribution rights to Histofreezer in 1998, implementation of a management bonus plan, and increased staffing. Operating loss increased to approximately $4.1 million in 1999 from approximately $2.3 million in 1998. Interest expense decreased to approximately $545,000 in 1999 from $570,000 in 1998 as a result of principal loan repayments. Interest income increased to approximately $595,000 in 1999 from approximately $468,000 in 1998 as a result of higher cash and cash equivalents. Foreign currency loss was approximately $141,000 in 1999. 32

The net loss increased to approximately $4.2 million in 1999 from approximately $2.4 million in 1998. LIQUIDITY AND CAPITAL RESOURCES December 31, -------------------- (In thousands) 2000 1999 -------- -------- Cash and cash equivalents $ 5,096 $ 2,050 Short-term investments 14,956 12,288 Working capital 21,495 16,313 The Company's cash and short-term investments position increased $5.7 million to approximately $20.1 million at December 31, 2000, primarily as a result of the receipt of $19.8 million of proceeds from the exercise of stock options and warrants to purchase Common Stock. This increase was largely offset by the continued losses from operations, capital investment into the infrastructure of the Company's facilities, and continued principal term debt repayments. At December 31, 2000, the Company's working capital was approximately $21.5 million. Liquidity is expected to remain strong for the foreseeable future as a result of anticipated profitability in 2001. However, liquidity will be negatively affected by continued investment in research and development, construction of fully automated lateral flow manufacturing lines, principal loan repayments, and ongoing capital expenditure requirements. The combination of the Company's current cash position, available borrowings under the Company's credit facilities, and the Company's cash flow from operations is expected to be sufficient to fund the Company's foreseeable operating and capital needs. However, the Company's cash requirements may vary materially from those now planned due to many factors, including, but not limited to, the progress of the Company's research and development programs, the scope and results of clinical testing, changes in existing and potential relationships with strategic partners, the time and cost in obtaining regulatory approvals, the costs involved in obtaining and enforcing patents, proprietary rights and any necessary licenses, the ability of the Company to establish development and commercialization capacities or relationships, the costs of manufacturing, market acceptance of new products and other factors. Net cash used in operating activities was approximately $10.0 million, an increase of approximately $9.2 million over 1999 as a direct result of the 2000 net loss and increased accounts receivable levels as a result of continued sales growth. Partially offsetting these items were lower inventory levels and higher accruals and accounts payable levels. Excluding the non-recurring Merger-related expenses, net cash used in operating activities would have been approximately $2.4 million. Net cash used in investing activities was approximately $5.6 million, primarily as a result of the Company's investment into tenant fit-out costs, additional laboratory and manufacturing equipment, and information systems equipment, offset by the sale of certain short-term investments. Net cash provided by financing activities was approximately $18.7 million, primarily as a result of the proceeds received from the exercise of warrants and stock options of approximately $13.9 million and $5.7 million, respectively, partially offset by approximately $1.1 million of term debt repayments. At December 31, 2000, the Company had a $1.0 million working capital line of credit in place with a bank that accrues interest at LIBOR plus 235 basis points. There were no borrowings under this line of credit at December 31, 2000. This lending facility expires June 30, 2001. The Company anticipates that this facility will be renewed. At December 31, 2000, the Company had a $1.0 million equipment line of credit in place with a bank. Borrowings under this line of credit will accrue interest at a rate fixed at prime at the time of draw down. There were no 33

borrowings under this line of credit outstanding at December 31, 2000. The unused portion of this lending facility expires June 30, 2001. The Company anticipates that this facility will be renewed. The credit facilities require, among other items, the maintenance of minimum financial ratios, and first lien position on all assets. RECENT ACCOUNTING PRONOUNCEMENTS In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 101 "Revenue Recognition in Financial Statements." The bulletin draws on existing accounting rules and provided specific guidance on revenue recognition. The Company has followed such principles in its financial statements. In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities. SFAS No. 133, as amended by SFAS No. 137, "Accounting for Derivative Instruments and Hedging Activities - Deferral of Effective Date of FASB Statement No. 133 - an amendment of FASB Statement No. 133", which had to be adopted by the Company on January 1, 2001, provides a comprehensive and consistent standard for the recognition and measurement of derivatives and hedging activities. The Company does not currently hold derivative instruments or engage in hedging activities, and accordingly, the adoption of this pronouncement did not have any impact on the Company's financial position or results of operations. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. The Company does not hold material amounts of derivative financial instruments, other financial instruments, or derivative commodity instruments, and accordingly has no material market risk to report under this Item. See Note 2 to the Consolidated Financial Statements included under Item 14. In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities. SFAS No. 133, as amended by SFAS No. 137, "Accounting for Derivative Instruments and Hedging Activities - Deferral of Effective Date of FASB Statement No. 133 - an amendment of FASB Statement No. 133", which had to be adopted by the Company on January 1, 2001, provides a comprehensive and consistent standard for the recognition and measurement of derivatives and hedging activities. The Company does not currently hold derivative instruments or engage in hedging activities, and accordingly, the adoption of this pronouncement did not have any impact on the Company's financial position or results of operations. The Company's holdings of financial instruments are comprised of U.S. corporate debt, certificates of deposit, government securities and commercial paper. All such instruments are classified as securities available for sale. The Company's debt security portfolio represents funds held temporarily pending use in its business and operations. The Company seeks reasonable assuredness of the safety of principal and market liquidity by investing in rated fixed income securities while at the same time seeking to achieve a favorable rate of return. Market risk exposure consists principally of exposure to changes in interest rates. If changes in interest rates would affect the investments adversely, the Company continues to hold the security to maturity. The Company's holdings are also exposed to the risks of changes in the credit quality of issuers. The Company typically invests in the shorter end of the maturity spectrum. The Company does not currently have any foreign currency exchange contracts or purchase currency options to hedge local currency cash flows. The Company has operations in The Netherlands which are subject to foreign currency fluctuations. As currency rates change, translation of income statements of these operations from local currencies to U.S. dollars affects year-to-year comparability of operating results. The Company's foreign operations represented approximately $4.0 million or 14% of the Company's revenues for the year ended December 31, 2000. Management does not expect the risk of foreign currency fluctuations to be material. ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To OraSure Technologies, Inc.: We have audited the accompanying balance sheets of OraSure Technologies, Inc. (a Delaware corporation) as of December 31, 2000 and 1999, and the related statements of operations, stockholders' equity and cash flows for the year ended December 31, 2000, the three months ended December 31, 1999, and for each of the two years in the period ended September 30, 1999. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We did not audit the financial statements of Epitope, Inc., a company acquired during 2000 in a transaction accounted for as a pooling of interests, as discussed in Note 1. Such statements are included in the financial statements of OraSure Technologies, Inc. and reflect total assets of 34 percent at December 31, 1999 and total revenues of 39 percent, 42 percent and 48 percent for the three months ended December 31, 1999 and years ended September 30, 1999 and 1998, respectively, of the related totals. Those statements were audited by other auditors whose report has been furnished to us, and our opinion, insofar as it relates to amounts included for Epitope, Inc., is based solely upon the report of the other auditors. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits and the report of other auditors provide a reasonable basis for our opinion. In our opinion, based on our audits and the report of other auditors, the financial statements referred to above present fairly, in all material respects, the financial position of OraSure Technologies, Inc. as of December 31, 2000 and 1999, and the results of its operations and its cash flows for the year ended December 31, 2000, the three months ended December 31, 1999, and for each of the two years in the period ended September 30, 1999, in conformity with accounting principles generally accepted in the United States. /S/ ARTHUR ANDERSEN LLP Philadelphia, Pennsylvania February 23, 2001 F-2

ORASURE TECHNOLOGIES, INC. NOTES TO THE FINANCIAL STATEMENTS 1. BACKGROUND: ----------- The Company - ----------- OraSure Technologies, Inc. (the "Company") develops, manufactures and markets oral specimen collection devices using its proprietary oral fluid technologies, oral fluid assays, proprietary diagnostic products including in vitro diagnostic tests, and other medical devices. These products are sold to public and private-sector clients, clinical laboratories, physician offices, hospitals, and for workplace point-of-care testing in the United States and certain foreign countries. Merger - ------ On September 29, 2000, STC Technologies, Inc. ("STC") and Epitope, Inc. ("Epitope") were merged (the "Merger") into the Company, a newly formed subsidiary of Epitope incorporated under Delaware law solely for the purposes of combining the two companies and changing the state of incorporation of Epitope from Oregon to Delaware. The companies were merged pursuant to an Agreement and Plan of Merger, dated May 6, 2000 (the "Merger Agreement"), by and among Epitope, the Company and STC. The shareholders of STC and Epitope approved the Merger Agreement on September 29, 2000. As a result of the Merger, each share of STC common stock was converted into five and two hundred ninety-six one thousandths (5.296) shares of the Company's common stock and each share of Epitope common stock was converted into one share of the Company's common stock. Of the 36,434,004 shares of common stock of the Company issued and outstanding at December 31, 2000, 18,373,884 shares were issued to the former stockholders of STC. The Merger was accounted for as a pooling of interests and, accordingly, all prior period financial statements of Epitope have been restated to include the results of operations, financial position and cash flows of STC. Information concerning common stock, employee stock plans and per share data has been restated on an equivalent share basis. The financial statements as of September 30, 1999 and for each of the two years in the period ended September 30, 1999 include Epitope's previous September 30 fiscal year amounts and STC's December 31 calendar year amounts for the corresponding fiscal years of Epitope. Change in year-end - ------------------ On September 29, 2000, the Board of Directors of Epitope approved a change in the fiscal year-end of Epitope from September 30 to December 31, effective with the calendar year beginning January 1, 2000. A three-month transition period from October 1, 1999 through December 31, 1999 (the "Transition Period") precedes the start of the 2000 fiscal year. "1999" and "1998" refer to the respective years ended September 30, and include Epitope's previous September 30 fiscal year amounts and STC's December 31 calendar year amounts for the corresponding fiscal years of Epitope, and "2000" refers to the twelve months ended December 31, 2000. As a result of the Merger, financial statements for the Transition Period include amounts for Epitope and STC for the three months ended December 31, 1999. Accordingly, STC's results of operations for the three months ended December 31, 1999 are included in both the financial statements for 1999 and for the Transition Period. Included in the statement of stockholders' equity is a $152,018 adjustment for the change in fiscal year-end, which represents STC's results of operations for the three months ended December 31, 1999 that is included in both 1999 and the Transition Period. F-9

The reconciliation of revenues, operating income (loss) and net income (loss) of Epitope and STC for the periods prior to the combination are as follows: Three months ended Year ended September 30, December 31, ------------------------ 1999 1999 1998 ------------ ----------- ----------- Revenues: Epitope $ 2,669,026 $10,031,020 $ 9,791,582 STC 4,152,628 14,015,001 10,652,444 ------------ ----------- ----------- Combined $ 6,821,654 $24,046,021 $20,444,026 ============ =========== =========== Operating income (loss): Epitope $ (549,488) $(3,515,544) $(2,281,834) STC 266,576 (576,318) 5,298 ------------ ----------- ----------- Combined $ (282,912) $(4,091,862) $(2,276,536) ============ =========== =========== Net income (loss): Epitope $ (481,725) $(3,237,644) $(1,928,008) STC 10,438 (995,620) (446,138) ------------ ----------- ----------- Combined $ (471,287) $(4,233,264) $(2,374,146) ============ =========== =========== There were no material adjustments required to conform the accounting policies of the two companies. Certain amounts of Epitope have been reclassified to conform to the current presentation. The amounts depicted above for Epitope for the Transition Period have been adjusted to reflect the elimination of intercompany transactions between Epitope and STC. Accordingly, these amounts will differ from the results as previously published by Epitope on Form 10-Q for the three months ended December 31, 1999. In connection with the Merger, the Company recorded merger-related expenses of $7.6 million. The categories of costs incurred, the actual cash payments made in 2000 and the accrued balances at December 31, 2000 are summarized below: Accrued Amounts Balance at Paid in December 31, Total 2000 2000 -------------------------------------- Cash costs Transaction costs $ 5,273,748 $5,273,748 $ -- Employee costs 1,079,607 497,982 581,625 Other integration costs 608,393 499,268 109,125 ----------- ---------- --------- 6,961,748 $6,270,998 $ 690,750 ========== ========= Non-cash costs 645,410 ----------- Total $ 7,607,158 =========== Transaction costs include investment banking, legal, accounting, printing and other direct costs of the Merger. Employee costs represent severance benefits paid to terminated employees whose responsibilities were deemed redundant as a result of the Merger, as well as certain relocation expenses. Accrued employee costs at December 31, 2000 will be paid to the employees through the second quarter of 2001. F-10

Other integration costs include financial system conversion costs and integration-related travel expenses. The non-cash charge of $645,410 represents the amount of unamortized deferred compensation on certain nonqualified options granted by Epitope in prior years, which was immediately accelerated upon the closing of the Merger under terms of Epitope's stock option plans. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: ------------------------------------------- Use of Estimates - ---------------- The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts 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. Cash and Cash Equivalents - ------------------------- The Company considers all highly liquid investments purchased with an original maturity of ninety days or less to be cash equivalents. As of December 31, 2000, cash equivalents consisted of certificates of deposit, commercial paper and U.S. government agency obligations. Short-term Investments - ---------------------- Short-term investments consist of treasury notes, certificates of deposits and other government obligations with original maturities greater than ninety days and less than one year. Such investments are recorded at fair value due to the nature of the maturities. Supplemental Cash Flow Information - ---------------------------------- For 2000, the Transition Period, 1999 and 1998, the Company paid interest of $490,410, $135,357, $565,025 and $495,667, respectively. For 2000, the Transition Period, 1999 and 1998, the Company recorded provisions for bad debts of $0, $0, $8,851, and $17,229, respectively. The Company had deductions of $4,269, $0, $0 and $0 against the allowance for doubtful accounts in 2000, the Transition Period, 1999 and 1998, respectively. Inventories - ----------- Inventories are stated at the lower of cost or market determined on a first-in, first-out basis. The Company currently buys its entire Histofreezer product from a foreign vendor. Purchases are payable in foreign currency. Changes in the exchange rate would impact the Company's product cost. Property and Equipment - ---------------------- Property and equipment are stated at cost. Additions or improvements are capitalized, while repairs and maintenance are charged to expense. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the related assets or the lease term, whichever is shorter. Buildings are depreciated over 20 years, while computer equipment, machinery and equipment, and furniture and fixtures are depreciated over 3 to 7 years. Leasehold improvements are generally amortized over the shorter of the estimated useful lives or the terms of the related leases. When assets are sold or otherwise disposed of, the related property amounts are relieved from the accounts, and any gain or loss is recorded in the statement of operations. Patents and Product Rights - -------------------------- Patents and product rights consist of costs associated with the acquisition of patents and product distribution rights and direct costs associated with patent submissions. Patents and product rights are amortized using the straight-line method over estimated useful lives of five to ten years. Amortization F-11

expense for 2000, the Transition Period, 1999 and 1998 was $816,111, $123,366, $482,106 and $372,703, respectively. Long-term Investments - --------------------- Included in other assets is an investment in a warrant to purchase 50,000 shares of LabOne, Inc. common stock, which is classified as available-for-sale securities in accordance with Statement of Financial Accounting Standards ("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, 2000 and 1999, the Company had $250,000 and $200,000 of unrealized losses related to these securities, respectively. Revenue Recognition - ------------------- The Company recognizes product revenues when products are shipped. The Company does not grant price protection or product return rights to its customers. Up front licensing fees are deferred and recognized ratably over the related license period. Product development revenues are recognized over the period the related product development efforts are performed. Amounts received prior to the performance of product development efforts are recorded as deferred revenues. In December 1999, the U.S. Securities and Exchange Commission issued Staff Accounting Bulletin No. 101 "Revenue Recognition in Financial Statements" ("SAB 101"). The bulletin draws on existing accounting rules and provides specific guidance on revenue recognition of up-front non-refundable license and development fees. The Company has applied the provisions of SAB 101 in the accompanying financial statements. Significant Customer Concentration - ---------------------------------- In 2000, 1999, and 1998, one customer accounted for approximately 23 percent, 19 percent, and 20 percent of total revenues, respectively. The same customer accounted for 20 percent and 16 percent of accounts receivable as of December 31, 2000 and 1999, respectively. Research and Development - ------------------------ Research and development costs are charged to expense as incurred. Income Taxes - ------------ The Company follows SFAS No. 109, "Accounting for Income Taxes" ("SFAS No. 109"), pursuant to which the liability method is used in accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using enacted tax rates that are expected to be in effect when the differences reverse. Foreign Currency Translation - ---------------------------- Pursuant to SFAS No. 52, "Foreign Currency Translation," the assets and liabilities of the Company's foreign operations are translated into U.S. dollars at current exchange rates as of the balance sheet date, and revenues and expenses are translated at average exchange rates for the period. Resulting translation adjustments are reflected as a separate component of stockholders' equity. Stock-Based Compensation - ------------------------ The Company accounts for stock-based compensation to employees using the intrinsic value method in accordance with Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees." The Company accounts for stock-based compensation to nonemployees using the fair value F-12

method in accordance with SFAS No. 123, "Accounting for Stock-Based Compensation" and Emerging Issues Task Force 96-18. Net Loss Per Common Share - ------------------------- The Company has presented basic and diluted net loss per share pursuant to SFAS No. 128, "Earnings per Share" ("SFAS 128"), and the Securities and Exchange Commission Staff Accounting Bulletin No. 98. In accordance with SFAS 128, basic and diluted net loss per share has been computed using the weighted-average number of shares of common stock outstanding during the period. Diluted loss per share is generally computed assuming the conversion or exercise of all dilutive securities such as common stock options and warrants; however, outstanding common stock options and warrants to purchase 4,677,357, 6,907,212, 7,002,673, and 6,495,506 shares were excluded from the computation of diluted net loss per common share for 2000, the Transition Period, 1999 and 1998, respectively, because they were anti-dilutive due to the Company's losses. Impairment of Long-Lived Assets - ------------------------------- In accordance with SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of," if indicators of impairment exist, the Company assesses the recoverability of the affected long-lived assets, which include property and equipment and patents and product rights, by determining whether the carrying value of such assets can be recovered through undiscounted future operating cash flows. If impairment is indicated, the Company measures the amount of such impairment by comparing the carrying value of the assets to the present value of the expected future cash flows associated with the use of the asset. Management believes the future cash flows to be received from the long-lived assets will exceed the assets' carrying value, and accordingly the Company has not recognized any impairment losses through December 31, 2000. Other Comprehensive Income (Loss) - --------------------------------- The Company follows SFAS No. 130, "Reporting Comprehensive Income." This statement requires the classification of items of other comprehensive income (loss) by their nature and disclosure of the accumulated balance of other comprehensive income (loss), separately from retained earnings and additional paid-in capital, in the equity section of the balance sheet. Recent Accounting Pronouncements - -------------------------------- In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities. SFAS No. 133, as amended by SFAS No. 137, "Accounting for Derivative Instruments and Hedging Activities - Deferral of Effective Date of FASB Statement No. 133 - an amendment of FASB Statement No. 133", which had to be adopted by the Company on January 1, 2001, provides a comprehensive and consistent standard for the recognition and measurement of derivatives and hedging activities. The Company does not currently hold derivative instruments or engage in hedging activities, and accordingly, the adoption of this pronouncement did not have any impact on the Company's financial position or results of operations. Gain on Sale of Securities - -------------------------- In December 1996, a subsidiary of the Company completed a merger with Andrew and Williamson Sales, Co. ("A&W"), which was rescinded on May 27, 1997. The Company received A&W preferred stock in the recission, which had been carried at zero value due to the circumstances surrounding A&W's financial condition at the time the stock was received in 1997. In 2000, the Company sold the A&W preferred stock for $600,000. F-13

ACQUISITION OF PATENTS AND PRODUCT RIGHTS: ------------------------------------------ On June 9, 1998, the Company acquired the patents and exclusive worldwide distribution rights to the Histofreezer product. The purchase price of $2,548,690, including transaction costs, has been recorded as patents and product rights and is being amortized using the straight-line method over an estimated useful life of 10 years. In connection with the acquisition, the Company also entered into a five-year production agreement with the seller of the Histofreezer product. 6.

7. CREDIT FACILITIES: ------------------ The Company has a $1,000,000 revolving line of credit with a bank which bears interest at LIBOR plus 235 basis points. Borrowings under this line are collateralized by the Company's accounts receivable. The line expires on June 30, 2001. There were no borrowings against the line at December 31, 2000 or 1999. The Company also has a $1,000,000 equipment facility with a bank, with interest fixed at the bank's prime rate on the date of commencement. Borrowings under this line are collateralized by the equipment financed. There were no outstanding borrowings under this facility as of December 31, 2000 or 1999. The unused portion of the equipment facility expires on June 30, 2001. These credit facilities require, among other items, the maintenance of certain financial covenants. 8.

9. INCOME TAXES: ------------- At December 31, 2000, the Company had net operating loss carryforwards for federal income tax purposes of approximately $64.4 million that have begun to expire and will continue to expire through 2020. The Tax Reform Act of 1986 contains provisions that may limit the annual amount of net operating loss carryforward available to be used in any given year in the event of significant changes in ownership. In connection with the Merger, a change in ownership occurred. Management believes the annual limitation will not have a material effect on the Company's ability to utilize its loss carryforwards. Given the Company's losses in recent years, management believes a valuation allowance is needed as of December 31, 2000. The tax effect of temporary differences as established in accordance with SFAS No. 109 that give rise to deferred income taxes is as follows: December 31, ----------------------------- 2000 1999 ------------ ------------- Deferred tax asset: Net operating loss carryforwards $ 24,901,000 $ 20,355,000 Stock based compensation 2,253,000 1,945,000 Accruals and reserves currently not deductible 1,384,000 1,267,000 Patent costs 491,000 526,000 Research and development credit carryforwards 1,677,000 1,427,000 Valuation allowance on deferred tax assets (30,706,000) (25,520,000) ------------ ------------- $ -- $ -- ============ ============= 10. STOCKHOLDERS' EQUITY: --------------------- Stock Options - ------------- As a result of the Merger, the Epitope, Inc. 2000 Stock Award Plan was adopted by the Company and renamed the OraSure Technologies, Inc. 2000 Stock Award Plan (the "2000 Plan"). The 2000 Plan permits stock-based awards to employees, outside directors and consultants or other third-party advisors. Awards which may be granted under the 2000 Plan include qualified incentive stock options, nonqualified stock options, stock appreciation rights, restricted awards, performance awards and other stock-based awards. Under the terms of the 2000 Plan, qualified incentive stock options on shares of common stock may be granted to eligible employees, including officers of the Company. To date, options have generally been granted with ten year exercise periods and an exercise price not less than the fair market value on date of grant. Options generally vest over four years, with one quarter of the options vesting one year after grant with the remainder vesting on a monthly basis over the next three years. The 2000 Plan also provides that nonqualified options may be granted at a price not less than 75 percent of the fair market value of a share of common stock on the date of grant. The option term and vesting schedule of such awards may either be unlimited or have a specified period in which to vest and be exercised. For the discounted nonqualified options issued, the Company amortizes, on a straight-line basis over the vesting period of the options, the difference between the exercise price and the fair market value of a share of stock on the date of grant. The Company applies Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees," and the related interpretations in accounting for its stock option plans. Accordingly, compensation expense is recognized for the intrinsic value (the difference between the exercise price and the fair value of the Company's common stock) on the date of grant. Compensation, if any, is deferred and charged to expense over the respective vesting period. In 2000, the Company issued an executive 375,000 options to purchase common stock for $4.59 per share. The fair market value of the Company's common stock at the date of issuance was $6.13. The Company recorded compensation of $577,500 on the date of F-16

grant to be amortized over the vesting period of three years. However, the options immediately vested upon the closing of the Merger in accordance with change in control rights contained in the stock option plans. As a result, the Company recorded $577,500 of compensation expense in 2000 related to the options. The Company recorded an additional $215,185 of compensation expense in 2000 due to the amortization of deferred compensation related to other stock options due to the change in control rights provided under the Epitope stock option plans. Under SFAS No. 123, "Accounting for Stock-Based Compensation," compensation cost related to stock options granted to employees is computed based on the value of the stock option at the date of grant using an option valuation methodology, typically the Black-Scholes pricing model. The Company follows the disclosure requirements of SFAS No. 123, "Accounting for Stock-Based Compensation." Had compensation cost for the Company's common stock option plan been determined based upon the fair value of the options at the date of grant, as prescribed under SFAS No. 123, the Company's net loss for 2000, 1999 and 1998 would have increased as follows: Year ended Year ended September 30, December 31, -------------------------- 2000 1999 1998 ------------ ------------ ------------ Net loss: As reported $(12,746,550) $ (4,233,264) $ (2,374,146) ============ ============ ============ Pro forma $(17,611,122) $ (6,553,202) $ (5,439,224) ============ ============ ============ Basic and diluted net loss per share: As reported $ (0.36) $ (0.14) $ (0.09) ============ ============ ============ Pro forma $ (0.50) $ (0.21) $ (0.21) ============ ============ ============ The weighted average fair value of the options granted during 2000, 1999 and 1998, is estimated at $4.96, $2.44 and $1.62, respectively, per share, using the Black-Scholes option pricing model with the following assumptions: dividend yield of zero; volatility of 64 percent, 55 percent and 50 percent, respectively; weighted average risk-free interest rate of 6.13 percent, 5.31 percent and 5.70 percent, respectively; and an expected life of 7.0, 4.3 and 3.9 years, respectively.

Employee Stock Purchase Plan - ---------------------------- In 1993, the shareholders approved Epitope's adoption of the 1993 Employee Stock Purchase Plan ("1993 ESPP"). The plan, as subsequently approved and amended by Epitope's shareholders, covers a maximum of 500,000 shares of common stock for subscription over established offering periods. As a result of the Merger, the 1993 ESPP was adopted and renamed by the Company. The Compensation Committee of the Board of directors determines the number of offering periods, the number of shares offered, and the length of each period, provided that no more than three offering periods may be set during each fiscal year of the Company. The purchase price for stock purchased under the 1993 ESPP for each subscription period is the lesser of 85 percent of the fair market value of a share of common stock at the commencement of the subscription period or the fair market value at the close of the subscription period. An employee may also elect to withdraw at any time during the subscription period and receive the amounts paid plus interest at the rate of 6 percent. As of December 31, 2000, 4,907 shares of common stock were subscribed for through one offering. Shares subscribed for under this 1993 ESPP offering may be purchased over 24 months and had an initial subscription price of $3.96. During the year ended December 31, 2000, 70,253 shares were issued at prices ranging from $2.74 to $4.78 per share under the 1993 ESPP. As of September 30, 1999, 82,712 shares of common stock were subscribed for through two offerings under the 1993 ESPP. Shares subscribed for under these offerings may be purchased over 24 months and had initial subscription prices of $6.99 and $2.74 per share. The subscription prices for the offering prior to December 30, 1997 were adjusted in fiscal 1998 from $6.99 to $4.78 per share, as a result of the spin-off of a former subsidiary of Epitope. During the year ended September 30, 1999, 16,002 shares were issued at prices ranging from $2.74 to $4.78 under the 1993 ESPP. F-19

The weighted average assumptions used for 1993 ESPP rights for 2000, 1999, and 1998 were a risk-free interest rate of 6.0 percent, 5.8 percent, and 5.6 percent, respectively; no expected dividend yield; an expected life of 2.0, 1.0 and 2.0 years, respectively; and an expected volatility of 61 percent, 69 percent, and 69 percent, respectively. The weighted-average fair value of 1993 ESPP rights granted in 2000, 1999, and 1998 were $9,843, $141,397, and $55,066, respectively. Common Stock Warrants - --------------------- As of December 31, 2000, the following warrants to purchase shares of common stock were outstanding: Date of Issuance Shares Exercise Price Expiration Date - ---------------- ------ -------------- --------------- July 15, 1992 50,000 $16.44 July 15, 2002 September 30, 1998 120,000 $ 6.13 September 30, 2008 ------- 170,000 In 2000, warrants to purchase 2,405,907 shares of common stock were exercised for total net proceeds of $13,865,370. 11. COMMITMENTS AND CONTINGENCIES: ------------------------------ Phosphor Agreements - ------------------- In April 1995, the Company entered into several research, licensing and royalty agreements (collectively the "Phosphor Agreements"), with certain amendments through August 2000. The Phosphor Agreements require, among other things, the Company to make annual license payments and pay royalties on the net sales of related product, research and development fees, and sublicensing revenues. In July 1999, the Company acquired the patent rights (the "Rights") to such phosphor technology thus amending the Company's requirements to make annual license payments, pay royalties and pay sublicensing fees. The Company paid approximately $1,400,000 for the rights and incurred approximately $100,000 of expenses related to the buyout of the Rights. The Company has accounted for the purchase price of the Rights as acquired in-process technology expenses because, at the date of the transaction, the technology rights acquired by the Company related to UPT had not progressed to a stage where it met technological feasibility and there existed a significant amount of uncertainty as to the Company's ability to complete the development of the technology which would achieve market acceptance within a reasonable timeframe. In addition, the acquired in-process technology did not have an alternative future use to the Company that had reached technological feasibility. In connection with the buyout, the Company is required to pay royalties of $25,000 per year until the Rights expire. The Company must also pay sponsored research funds of $125,000 per year through July 2002, and $50,000 per year thereafter until the Rights expire. F-20

Leases - ------ The Company leases office, manufacturing, warehouse and laboratory facilities under operating lease agreements. Future payments required under these leases are as follows: 2001 $ 647,028 2002 654,225 2003 651,534 2004 662,514 2005 and thereafter 99,979 ---------- $2,715,280 ========== Rent expense for 2000, 1999 and 1998 was $716,748, $461,105 and $459,536, respectively. Employment Agreements - --------------------- Under terms of employment agreements with certain executive officers extending through 2003, the Company is required to pay each officer a base salary. The agreements require payments of $1,135,008, $1,022,508 and $487,503 in 2001, 2002 and 2003, respectively. Litigation - ---------- From time-to-time, the Company is involved in certain legal actions arising in the ordinary course of business. In management's opinion, based upon the advice of counsel, the outcome of such actions are not expected to have a material adverse effect on the Company's future financial position or results of operations. 12. RELATED-PARTY TRANSACTIONS: --------------------------- In March and October 2000, the Company issued notes receivable to an officer of the Company ("Officer Notes") for $75,000 and $100,649, respectively, for relocation purposes. The Officer Notes do not bear interest if they are repaid on or before the earlier of the tenth day following the close of sale on the officer's previous residences or the first anniversary date of the Officer notes. In the event the Officer Notes are not repaid in the period defined, they will bear interest at nine percent per year. 13. RETIREMENT PLANS: ----------------- As a result of the Merger, the Company currently maintains two distinct retirement plans covering substantially all of its employees. Both plans permit certain voluntary employee contributions to be excluded from the employees' current taxable income under the provisions of Internal Revenue Code Section 401(k) and the regulations there under. During 2001, the Company intends to combine these two retirement plans into one surviving plan having similar provisions. During the periods reported, generally all employees of Epitope were eligible to participate in a profit sharing and deferred savings plan. The plan provides for a Company matching contribution (either in cash, Company stock, or a combination of both) equal to 50 percent of an employee's contribution, not to exceed 2.5 percent of an employee's compensation. The Company contributed $62,409 (5,309 shares), $17,492 (2,691 shares), $75,475 (12,693 shares) and $80,740 (17,260 shares) during 2000, the Transition Period, 1999 and 1998, respectively. During the periods reported, generally all employees of STC were eligible to participate in a profit sharing plan. The plan provides for the Company, subject to the Board of Directors' discretion, to match employee contributions up to $3,000 or 8% of a participant's salary, whichever is less. Company contributions to the plan were $122,903, $19,247, $113,708 and $93,607 for 2000, the Transition Period, 1999 and 1998, respectively. F-21

               1.1  EMPLOYMENT.   The  Company  agrees  to  employ  Employee  as
president  and chief  executive  officer of the  Company,  and  Employee  hereby

Agreement.  Employment shall continue until terminated  pursuant to the terms of
this Agreement.

provided by the bylaws of the Company,  (b) as otherwise  set forth in Exhibit A
attached to this Agreement, and (c) as determined by the board of directors from
time to time.  Subject to the  provisions  of  Section  6.4  hereof,  Employee's
position  and duties may be  changed  from time to time  during the term of this
Agreement.  Employee's place of work shall be the Company's headquarters, at its
present location or as it may be relocated.

               1.3   OUTSIDE  ACTIVITIES.  Employee  shall obtain the consent of
the board of directors before he engages, either directly or indirectly,  in any
other  professional  or  business  activities  that may  require an  appreciable
portion of Employee's time or effort to the detriment of the Company's business.
The Company  consents to the consulting  agreement  between Employee and LabOne,
Inc., under which Employee will provide services to LabOne, Inc. ending no later
than March 31, 2000.

               1.4   DIRECTION  OF  SERVICES.   Employee   shall  at  all  times
discharge  his  duties  in  consultation  with and  under  the  supervision  and
direction of the board of directors.

               2.1   SALARY.  As compensation for services under this Agreement,
the Company  shall pay to  Employee a regular  salary of  $22,916.67  per month.
Subject to the  provisions  of Section 6.4  hereof,  such salary may be adjusted
from time to time in the discretion of the board of directors.  Payment shall be
made on a bi-weekly  basis,  less all amounts  required by law or  authorized by
Employee to be withheld or deducted.  The board of directors may also  authorize

2.3 EXPENSES. 2.3.1 JOB-RELATED. The Company shall reimburse Employee for all reasonable and necessary expenses incurred in carrying out his duties under this Agreement. 2.3.2 RELOCATION EXPENSES. The Company shall further reimburse Employee for reasonable and necessary expenses incurred as follows: (a) reasonable expenses incurred by Employee in moving himself, his family, and his household goods from Olathe, Kansas, to the Portland, Oregon, metropolitan area (not to exceed $10,000 without the approval of the chairman of the board in his discretion at Employee's request); (b) up to three months of temporary housing at a cost of up to $2,800 per month (or such longer time period and/or amount as may be approved by the chairman of the board in his discretion at Employee's request); (c) one round-trip, coach airline ticket per month (up to a maximum of six) for Employee for travel between Olathe, Kansas, and Portland, Oregon, until Employee has relocated his residence to the Portland, Oregon, metropolitan area; and (d) two round-trip, coach airline tickets for Employee's spouse for travel between Olathe, Kansas, and Portland, Oregon, for purposes of locating and obtaining a new residence in the Portland, Oregon metropolitan area.

To the extent the payments under Sections 2.3.2 or 2.3.3 are includable in Employee's net taxable income, the Company shall pay Employee an additional amount so that the amount paid to him, less taxes at Employee's effective marginal tax rate, equals the amounts required to be paid to him under those sections. 2.3.5 REAL ESTATE LOAN. The Company will loan Employee up to $75,000 to be applied toward Employee's purchase of a home in the Portland, Oregon metropolitan area. The loan will not bear interest, will be secured by a second position mortgage on the home purchased, will be subject to Employee's execution of loan documentation satisfactory to the Company, and will be repayable upon Employee's sale of his Kansas residence. 2.4 FEES.

Employee shall pay or deliver such compensation to the Company promptly upon receipt. For the purposes of this provision, "compensation" shall include, but is not limited to, all professional and nonprofessional fees, lecture fees, expert testimony fees, publishing fees, royalties, and any related income, earnings, or other things of value; and "scientific or business activities of the Company" shall include, but not be limited to, any project or projects in which the Company is involved and any subject matter that is directly or indirectly researched, tested, developed, promoted, or marketed by the Company. -2-

The options will vest over a three-year period, with one-third of the options to vest on the first anniversary of the grant date and the remainder to vest on a monthly basis thereafter. 4. MATERIALS PREPARED AND INVENTIONS MADE DURING EMPLOYMENT. The Company shall be the exclusive owner of all materials, concepts, and inventions Employee prepares, develops, or makes (whether alone or jointly with others) within the scope of his employment, and of all related rights (including copyrights, trademarks, and patents) and proceeds. Without limitation, materials, concepts, and inventions that (a) relate to the Company's business or actual or demonstrably anticipated research or development, or (b) result from any work performed by Employee for the Company, shall be considered within the scope of Employee's employment. Employee shall promptly disclose all such materials, concepts, and inventions to the Company. Employee shall take all action reasonably requested by the Company to vest ownership of such materials, consents, and inventions in the Company and to permit the Company to obtain copyright, trademark, patent, or similar protection in its name. 5. BUSINESS PROTECTION AGREEMENT. Employee and the Company are concurrently entering a Business Protection Agreement. Employee's compliance with the terms of the Business Protection Agreement is a material requirement of this Agreement. 6. TERMINATION. 6.1 TERMINATION UPON DEATH. This Agreement shall terminate immediately upon Employee's death. 6.2 TERMINATION BY EMPLOYEE. Employee may terminate his employment under this Agreement by 60 days' written notice to the Company. 6.3 TERMINATION BY THE COMPANY FOR CAUSE. Officer's employment may be terminated by the Company at any time for cause. Only the following actions, failures, or events by or affecting Employee shall constitute "cause" for termination of Employee by the Company: (i) willful and continued failure by Employee to substantially perform his duties provided herein after a written demand for substantial performance is delivered to Employee by the Chairman of the Board of the Company, which demand identifies with reasonable specificity the manner in which Employee has not substantially performed his duties, and Employee's failure to comply with such demand within a reasonable time; (ii) the engaging by Employee in gross misconduct or gross negligence materially injurious to the Company; (iii) the commission of any act in direct competition with or materially detrimental to the best interests of the Company; or (iv) Employee's conviction of having committed a felony. Notwithstanding the foregoing, Employee shall not be deemed to have been terminated by the Company for cause unless and until there shall have been delivered to him a copy of a resolution duly adopted by the affirmative vote of not less than a majority of the entire membership of the board of directors of the Company finding that, in the good faith opinion of the board of directors, the Company has cause for the termination of the employment of Employee as set forth in any of clauses (i) -3-

through (iv) above and specifying the particulars thereof in reasonable detail. The findings of the board of directors shall not be binding on the arbitrators or other finders of fact in connection with any litigation or dispute arising out of this Agreement. 6.4 TERMINATION BY THE COMPANY WITHOUT CAUSE. The Company may terminate Employee's employment under this Agreement without cause by written notice to Employee. Employee may (but shall not be required to) elect to treat any of the following events as a termination without cause, provided Employee acts within 60 days of the event: 6.4.1 A material breach of this Agreement by the Company and a failure by the Company to cure the breach within 30 days after Employee has given written notice of the breach to the board of directors. 6.4.2 A reduction in Employee's salary below the amount stated in Section 2.1 (except as part of and in proportion to a reduction in all executive officers' salaries) or a change in Employee's title or a substantial diminution in Employee's duties below those stated in this Agreement. 6.4.3 A requirement by the Company that Employee regularly report other than to the board of directors or the chairman of the board. 6.4.4 A "Change of Control" of the Company. For purposes of this Agreement, a "Change of Control" shall mean a change of control of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A as in effect on the date hereof pursuant to the Securities Exchange Act of 1934 (the "Exchange Act"); provided that, without limitation, such a change of control shall be deemed to have occurred at such time as (i) any Acquiring Person hereafter becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of 30 percent or more of the combined voting power of Voting Securities; (ii) during any period of 12 consecutive calendar months, individuals who at the beginning of such period constitute the board of directors cease for any reason to constitute at least a majority thereof unless the election, or the nomination for election, by the Company's shareholders of each new director was approved by a vote of at least a majority of the directors then still in office who were directors at the beginning of the period; (iii) there shall be consummated (a) any consolidation or merger of the Company in which the Company is not the continuing or surviving corporation or pursuant to which Voting Securities would be converted into cash, securities, or other property, other than a merger of the Company in which the holders of Voting Securities immediately prior to the merger have the same, or substantially the same, proportionate ownership of common stock of the surviving corporation immediately after the merger, or (b) any sale, lease, exchange, or other transfer (in one transaction or a series of related transactions) of all, or substantially all, of the assets of the Company; or (iv) approval by the shareholders of the Company of any plan or proposal for the liquidation or dissolution of the Company. For purposes of this Agreement, "Acquiring Person" means any person or related persons which constitute a "group" for purposes of Section 13(d) and Rule 13d-5 under the Exchange Act, as such Section and Rule are in effect as of the date of this Agreement; provided, however, that the term Acquiring Person shall not include: (i) the Company or any of its subsidiaries; (ii) any employee benefit plan of the Company or any of its subsidiaries; (iii) any entity holding voting capital stock of the Company for or pursuant to the -4-

terms of any such employee benefit plan; or (iv) any person or group solely because such person or group has voting power with respect to capital stock of the Company arising from a revocable proxy or consent given in response to a public proxy or consent solicitation made pursuant to the Exchange Act. For purposes of this Agreement, "Voting Securities" means the Company's issued and outstanding securities ordinarily having the right to vote at elections for the Company's board of directors. 6.5 COMPENSATION UPON TERMINATION. 6.5.1 TERMINATION UNDER SECTION 6.1, 6.2, OR 6.3. In the event of a termination of Employee's employment under Sections 6.1, 6.2, or 6.3, Employee's regular compensation pursuant to Section 2.1 shall be prorated and payable until the date of termination and Employee shall be paid any bonus that has been approved but not yet paid. 6.5.2 TERMINATION UNDER SECTION 6.4. In the event of a termination of Employee's employment by the Company without cause as provided in Section 6.4, Employee shall continue to be paid the salary provided in Section 2.1 for 12 months from the date of notice of such termination of employment, in the manner and at the times at which regular compensation was paid to Employee during the term of his employment under this Agreement, except that if Employee elects to treat an event described in Sections 6.4.1, 6.4.2, 6.4.3, or 6.4.4 as a termination without cause but continues to work for the Company or any of its subsidiaries, then any amounts Employee receives as compensation during the 12-month period shall be credited against the amounts payable to Employee under this section. In no other respect shall the amount of any payment provided for in this section be reduced by any compensation or benefits earned by employee as a result of employment after his termination. As a condition to receipt of the compensation described in the first sentence of this Section 6.5.2, Employee shall sign and deliver a release agreement, in form and substance satisfactory to the Company and Employee, releasing all claims related to Employee's employment. The Company's obligation to pay the amounts stated in this section shall terminate if Employee fails to comply with the Business Protection Agreement within one year after termination of employment. 7. REMEDIES. The respective rights and duties of the Company and Employee under this Agreement are in addition to, and not in lieu of, those rights and duties afforded to and imposed upon them by law or at equity. 8. SEVERABILITY OF PROVISIONS. The provisions of this Agreement are severable, and if any provision hereof is held invalid or unenforceable, it shall be enforced to the maximum extent permissible, and the remaining provisions of the Agreement shall continue in full force and effect. 9. NONWAIVER. Failure by either party at any time to require performance of any provision of this Agreement shall not limit the right of the party failing to require performance to enforce the provision. No provision of this Agreement may be waived by either party except by a writing signed by that party. A waiver of any breach of a provision of this Agreement shall be construed narrowly and shall not be deemed to be a waiver of any succeeding breach of that provision or a waiver of that provision itself or of any other provision. -5-

10. ARBITRATION. 10.1 CLAIMS COVERED. All claims or controversies, except for those excluded by Section 10.2 ("claims"), whether or not arising out of Employee's employment (or its termination), that the Company may have against the Employee or that Employee may have against the Company or against its officers, directors, employees or agents, in their capacity as such or otherwise, shall be resolved as provided in this Section 10. Claims covered by this Section 10 include, but are not limited to, claims for wages or other compensation due; claims for breach of any contract or covenant (express or implied); tort claims; claims for discrimination (including, but not limited to, race, sex, sexual orientation, religion, national origin, age, marital status, or disability); claims for benefits (except where an employee benefit or pension plan specifies that its claims procedure shall culminate in an arbitration procedure different from this one), and claims for violation of any federal, state, or other governmental law, statute, regulation, or ordinance, except as provided in Section 10.2. 10.2 NON-COVERED CLAIMS. Claims arising out of the Business Protection Agreement and workers' compensation or unemployment compensation benefits are not covered by this Section 10. Non-covered claims include but are not limited to claims by the Company for injunctive and/or other equitable relief for unfair competition and/or the use and/or unauthorized disclosure of trade secrets or confidential information, as to which Employee understands and agrees that the Company may seek and obtain relief from a court of competent jurisdiction. 10.3 REQUIRED NOTICE OF ALL CLAIMS AND STATUTE OF LIMITATIONS. Company and Employee agree that the aggrieved party must give written notice of any claim to the other party within one year of the date the aggrieved party first has knowledge of the event giving rise to the claim; otherwise the claim shall be void and deemed waived even if there is a federal or state statute of limitations which would have given more time to pursue the claim. The written notice shall identify and describe the nature of all claims asserted and the facts upon which such claims are based. 10.4 ARBITRATION PROCEDURES. Any arbitration shall be conducted in accordance with the then-current Model Employment Arbitration Procedures of the American Arbitration Association ("AAA"), modified to substitute for AAA actions, the United States Arbitration and Mediation Service ("USA&MS"), before an arbitrator who is licensed to practice law in the state of Oregon (the "Arbitrator"). The arbitration shall take place in or near Portland, Oregon. 10.4.1 SELECTION OF ARBITRATOR. The USA&MS shall give each party a list of 11 arbitrators drawn from its panel of labor-management dispute arbitrators. Each party may strike all names on the list it deems unacceptable. If only one common name remains on the lists of all parties, that individual shall be designated as the Arbitrator. If more than one common name remains on the lists of all parties, the parties shall strike names alternately until only one remains. The party who did not initiate the claim shall strike first. If no common name remains on the lists of all parties, the USA&MS shall furnish an additional list or lists until an Arbitrator is selected. -6-

10.4.2 APPLICABLE LAW. The Arbitrator shall apply the substantive law (and the law of remedies, if applicable) specified in this Agreement or federal law, or both, as applicable to the claim(s) asserted. The Arbitrator, and not any federal, state, or local court or agency, shall have exclusive authority to resolve any dispute relating to the interpretation, applicability, enforceability or formation of this Agreement, including but not limited to any claim that all or any part of this Agreement is void or voidable. The arbitration shall be final and binding upon the parties, except as provided in this Agreement. 10.4.3 AUTHORITY. The Arbitrator shall have jurisdiction to hear and rule on pre-hearing disputes and is authorized to hold pre-hearing conferences by telephone or in person as the Arbitrator deems necessary. The Arbitrator shall have the authority to entertain a motion to dismiss and/or a motion for summary judgment by any party and shall apply the standards governing such motions under the Federal Rules of Civil Procedure. The Arbitrator shall render an award and opinion in the form typically rendered in labor arbitrations. 10.4.4 REPRESENTATION. Any party may be represented by an attorney or other representative selected by the party. 10.4.5 DISCOVERY. Each party shall have the right to take the deposition of one individual and any expert witness designated by another party. Each party also shall have the right to make requests for production of documents to any party. The subpoena right specified below shall be applicable to discovery pursuant to this paragraph. Additional discovery may be had only where the Arbitrator selected pursuant to this Agreement so orders, upon a showing of substantial need. At least 30 days before the arbitration, the parties must exchange lists of witnesses, including any experts, and copies of all exhibits intended to be used at the arbitration. Each party shall have the right to subpoena witnesses and documents for the arbitration. 10.4.6 REPORTER. Either party, at its expense, may arrange for and pay the cost of a court reporter to provide a stenographic record of proceedings. 10.4.7 POST-HEARING BRIEFS. Either party, upon request at the close of hearing, shall be given leave to file a post-hearing brief. The time for filing such a brief shall be set by the Arbitrator. 10.5 ENFORCEMENT. Either party may bring an action in any court of competent jurisdiction to compel arbitration under this Agreement and to enforce an arbitration award. Except as otherwise provided in this Agreement, both the Company and Employee agree that neither shall initiate or prosecute any lawsuit or administrative action (other than for a non-covered claim) in any way related to any claim covered by this Agreement. A party opposing enforcement of an award may not do so in an enforcement proceeding, but must bring a separate action in any court of competent jurisdiction to set aside the award, where the standard of review will be the same as that applied by an appellate court reviewing a decision of a trial court sitting without a jury. 10.6 ARBITRATION FEES AND COSTS. Company and Employee shall equally share the fees and costs of the Arbitrator. Each party will deposit funds or post other -7-

appropriate security for its share of the Arbitrator's fee, in an amount and manner determined by the Arbitrator, 10 days before the first day of hearing. Each party shall pay for its own costs and attorneys' fees, if any, provided that the Arbitrator, in its sole discretion, may award reasonable fees to the prevailing party in a proceeding. 11. GENERAL TERMS AND CONDITIONS. This Agreement constitutes the entire understanding of the parties relating to the employment of Employee by the Company, and supersedes and replaces all written and oral agreements heretofore made or existing by and between the parties relating thereto. This Agreement shall be construed in accordance with the laws of the state of Oregon, without regard to any contrary conflicts of laws rules thereof. This Agreement shall inure to the benefit of any successors or assigns of the Company. All captions used herein are intended solely for convenience of reference and shall in no way limit any of the provisions of this Agreement. Employee acknowledges that he signed this Agreement upon his initial employment with the Company. The parties have executed this Employment Agreement as of the date stated above.

issued and outstanding securities ordinarily having the right to vote at elections for the Company's board of directors. 6.5 COMPENSATION UPON TERMINATION. 6.5.1 TERMINATION UNDER SECTION 6.1, 6.2, OR 6.3. In the event of a termination of Employee's employment under Sections 6.1, 6.2, or 6.3, Employee's regular compensation pursuant to Section 3.1 shall be prorated and payable until the date of termination and Employee shall be paid any bonus that has been approved but not yet paid. 6.5.2 TERMINATION UNDER SECTION 6.4. In the event of a termination of Employee's employment by the Company without cause as provided in Section 6.4, Employee shall continue to be paid the salary provided in Section 3.1 for the greater of (a) 12 months, (b) the remaining term of this Agreement, or (c) 36 months if Employee elects to treat an event described in Section 6.4.4 as a termination without cause, from the date of notice of such termination of employment or the date of such event, in the manner and at the times at which regular compensation was paid to Employee during the term of his employment under this Agreement, except that if Employee elects to treat an event described in Sections 6.4.1, 6.4.2, 6.4.3, or 6.4.4 as a termination without cause but continues to work for the Company or any of its subsidiaries, then any amounts Employee receives as compensation following the event shall be credited against the amounts payable to Employee under this section. In no other respect shall the amount of any payment provided for in this section be reduced by any compensation or benefits earned by employee as a result of employment after his termination. As a condition to receipt of the compensation described in the first sentence of this Section 6.5.2, Employee shall sign and deliver a release agreement, in form and substance satisfactory to the Company and Employee, releasing all claims related to Employee's employment. The Company's obligation to pay the amounts stated in this section shall terminate if Employee fails to comply with the Business Protection Agreement within the applicable time period stated in the first sentence of this section. 7.

The provisions of this Agreement are severable, and if any provision hereof is held invalid or unenforceable, it shall be enforced to the maximum extent permissible, and the remaining provisions of the Agreement shall continue in full force and effect. 9. NONWAIVER. Failure by either party at any time to require performance of any provision of this Agreement shall not limit the right of the party failing to require performance to enforce the provision. No provision of this Agreement may be waived by either party except by a writing signed by that party. A waiver of any breach of a provision of this Agreement shall be construed narrowly and shall not be deemed to be a waiver of any succeeding breach of that provision or a waiver of that provision itself or of any other provision. -5-

10. ARBITRATION. 10.1 CLAIMS COVERED. All claims or controversies, except for those excluded by Section 11.2 ("claims"), whether or not arising out of Employee's employment (or its termination), that the Company may have against the Employee or that Employee may have against the Company or against its officers, directors, employees or agents, in their capacity as such or otherwise, shall be resolved as provided in this Section 11. Claims covered by this Section 11 include, but are not limited to, claims for wages or other compensation due; claims for breach of any contract or covenant (express or implied); tort claims; claims for discrimination (including, but not limited to, race, sex, sexual orientation, religion, national origin, age, marital status, or disability); claims for benefits (except where an employee benefit or pension plan specifies that its claims procedure shall culminate in an arbitration procedure different from this one), and claims for violation of any federal, state, or other governmental law, statute, regulation, or ordinance, except as provided in Section 11.2. 10.2 NON-COVERED CLAIMS. Claims arising out of the Business Protection Agreement and workers' compensation or unemployment compensation benefits are not covered by this Section 11. Non-covered claims include but are not limited to claims by the Company for injunctive and/or other equitable relief for unfair competition and/or the use and/or unauthorized disclosure of trade secrets or confidential information, as to which Employee understands and agrees that the Company may seek and obtain relief from a court of competent jurisdiction. 10.3 REQUIRED NOTICE OF ALL CLAIMS AND STATUTE OF LIMITATIONS. Company and Employee agree that the aggrieved party must give written notice of any claim to the other party within one year of the date the aggrieved party first has knowledge of the event giving rise to the claim; otherwise the claim shall be void and deemed waived even if there is a federal or state statute of limitations which would have given more time to pursue the claim. The written notice shall identify and describe the nature of all claims asserted and the facts upon which such claims are based. 10.4 ARBITRATION PROCEDURES. Any arbitration shall be conducted in accordance with the then-current Model Employment Arbitration Procedures of the American Arbitration Association ("AAA"), modified to substitute for AAA actions, the United States Arbitration and Mediation Service ("USA&MS"), before an arbitrator who is licensed to practice law in the state of Pennsylvania (the "Arbitrator"). The arbitration shall take place in or near Bethlehem, Pennsylvania. 10.4.1 SELECTION OF ARBITRATOR. The USA&MS shall give each party a list of 11 arbitrators drawn from its panel of labor-management dispute arbitrators. Each party may strike all names on the list it deems unacceptable. If only one common name remains on the lists of all parties, that individual shall be designated as the Arbitrator. If more than one common name remains on the lists of all parties, the parties shall strike names alternately until only one remains. The party who did not initiate the claim shall strike first. If no common name remains on the lists of all parties, the USA&MS shall furnish an additional list or lists until an Arbitrator is selected. -6-

10.4.2 APPLICABLE LAW. The Arbitrator shall apply the substantive law (and the law of remedies, if applicable) specified in this Agreement or federal law, or both, as applicable to the claim(s) asserted. The Arbitrator, and not any federal, state, or local court or agency, shall have exclusive authority to resolve any dispute relating to the interpretation, applicability, enforceability or formation of this Agreement, including but not limited to any claim that all or any part of this Agreement is void or voidable. The arbitration shall be final and binding upon the parties, except as provided in this Agreement. 10.4.3 AUTHORITY. The Arbitrator shall have jurisdiction to hear and rule on pre-hearing disputes and is authorized to hold pre-hearing conferences by telephone or in person as the Arbitrator deems necessary. The Arbitrator shall have the authority to entertain a motion to dismiss and/or a motion for summary judgment by any party and shall apply the standards governing such motions under the Federal Rules of Civil Procedure. The Arbitrator shall render an award and opinion in the form typically rendered in labor arbitrations. 10.4.4 REPRESENTATION. Any party may be represented by an attorney or other representative selected by the party. 10.4.5 DISCOVERY. Each party shall have the right to take the deposition of one individual and any expert witness designated by another party. Each party also shall have the right to make requests for production of documents to any party. The subpoena right specified below shall be applicable to discovery pursuant to this paragraph. Additional discovery may be had only where the Arbitrator selected pursuant to this Agreement so orders, upon a showing of substantial need. At least 30 days before the arbitration, the parties must exchange lists of witnesses, including any experts, and copies of all exhibits intended to be used at the arbitration. Each party shall have the right to subpoena witnesses and documents for the arbitration. 10.4.6 REPORTER. Either party, at its expense, may arrange for and pay the cost of a court reporter to provide a stenographic record of proceedings. 10.4.7 POST-HEARING BRIEFS. Either party, upon request at the close of hearing, shall be given leave to file a post-hearing brief. The time for filing such a brief shall be set by the Arbitrator. 10.5 ENFORCEMENT. Either party may bring an action in any court of competent jurisdiction to compel arbitration under this Agreement and to enforce an arbitration award. Except as otherwise provided in this Agreement, both the Company and Employee agree that neither shall initiate or prosecute any lawsuit (other than for a non-covered claim) in any way related to any claim covered by this Agreement. A party opposing enforcement of an award may not do so in an enforcement proceeding, but must bring a separate action in any court of competent jurisdiction to set aside the award, where the standard of review will be the same as that applied by an appellate court reviewing a decision of a trial court sitting without a jury. -7-

10.6 ARBITRATION FEES AND COSTS. Company and Employee shall equally share the fees and costs of the Arbitrator. Each party will deposit funds or post other appropriate security for its share of the Arbitrator's fee, in an amount and manner determined by the Arbitrator, 10 days before the first day of hearing. Each party shall pay for its own costs and attorneys' fees, if any, provided that the Arbitrator, in its sole discretion, may award reasonable fees to the prevailing party in a proceeding. 11. GENERAL TERMS AND CONDITIONS. This Agreement constitutes the entire understanding of the parties relating to the employment of Employee by the Company, and supersedes and replaces all written and oral agreements heretofore made or existing by and between the parties relating thereto. This Agreement shall be construed in accordance with the laws of the state of Pennsylvania, without regard to any contrary conflicts of laws rules thereof. This Agreement shall inure to the benefit of any successors or assigns of the Company. All captions used herein are intended solely for convenience of reference and shall in no way limit any of the provisions of this Agreement. Employee acknowledges that he signed this Agreement upon his initial employment with the Company. The parties have executed this Employment Agreement as of the date stated above.

For purposes of this Agreement, "Acquiring Person" means any person or related persons which constitute a "group" for purposes of Section 13(d) and Rule 13d-5 under the Exchange Act, as such Section and Rule are in effect as of the date of this Agreement; provided, however, that the term Acquiring Person shall not include: (i) the Company or any of its subsidiaries; (ii) any employee benefit plan of the Company or any of its subsidiaries; (iii) any entity holding voting capital stock of the Company for or pursuant to the terms of any such employee benefit plan; or (iv) any person or group solely because such person or group has voting power with respect to capital stock of the Company arising from a revocable proxy or consent given in response to a public proxy or consent solicitation made pursuant to the Exchange Act. For purposes of this Agreement, "Voting Securities" means the Company's issued and outstanding securities ordinarily having the right to vote at elections for the Company's board of directors. 6.5 COMPENSATION UPON TERMINATION. 6.5.1 TERMINATION UNDER SECTIONS 6.1, 6.2, OR 6.3. In the event of a termination of Employee's employment under Sections 6.1, 6.2, or 6.3, Employee's regular compensation pursuant to Section 3.1 shall be prorated and payable until the date of termination and Employee shall be paid any bonus that has been approved but not yet paid. 6.5.2 TERMINATION UNDER SECTION 6.4. In the event of a termination of Employee's employment by the Company without cause as provided in Section 6.4, Employee shall continue to be paid the salary provided in Section 3.1 for the greater of (a) 12 months, (b) the remaining term of this Agreement, or (c) 36 months if Employee elects to treat an event described in Section 6.4.3 as a termination without cause, from the date of notice of such termination of employment or the date of such event, in the manner and at the times at which regular compensation was paid to Employee during the term of his employment under this Agreement, except that if Employee elects to treat an event described in Sections 6.4.1, 6.4.2, or 6.4.3 as a termination without cause but continues to work for the Company or any of its subsidiaries, then any amounts Employee receives as compensation following the event shall be credited against the amounts payable to Employee under this section. In no other respect -4-

shall the amount of any payment provided for in this section be reduced by any compensation or benefits earned by employee as a result of employment after his termination. As a condition to receipt of the compensation described in the first sentence of this Section 6.5.2, Employee shall sign and deliver a release agreement, in form and substance satisfactory to the Company and Employee, releasing all claims related to Employee's employment. The Company's obligation to pay the amounts stated in this section shall terminate if Employee fails to comply with the Business Protection Agreement within the applicable time period stated in the first sentence of this section. 7. REMEDIES. The respective rights and duties of the Company and Employee under this Agreement are in addition to, and not in lieu of, those rights and duties afforded to and imposed upon them by law or at equity. 8. SEVERABILITY OF PROVISIONS. The provisions of this Agreement are severable, and if any provision hereof is held invalid or unenforceable, it shall be enforced to the maximum extent permissible, and the remaining provisions of the Agreement shall continue in full force and effect. 9. NONWAIVER. Failure by either party at any time to require performance of any provision of this Agreement shall not limit the right of the party failing to require performance to enforce the provision. No provision of this Agreement may be waived by either party except by a writing signed by that party. A waiver of any breach of a provision of this Agreement shall be construed narrowly and shall not be deemed to be a waiver of any succeeding breach of that provision or a waiver of that provision itself or of any other provision. 10. ARBITRATION. 10.1 CLAIMS COVERED. All claims or controversies, except for those excluded by Section 10.2 ("claims"), whether or not arising out of Employee's employment (or its termination), that the Company may have against the Employee or that Employee may have against the Company or against its officers, directors, employees or agents, in their capacity as such or otherwise, shall be resolved as provided in this Section 10. Claims covered by this Section 10 include, but are not limited to, claims for wages or other compensation due; claims for breach of any contract or covenant (express or implied); tort claims; claims for discrimination (including, but not limited to, race, sex, sexual orientation, religion, national origin, age, marital status, or disability); claims for benefits (except where an employee benefit or pension plan specifies that its claims procedure shall culminate in an arbitration procedure different from this one), and claims for violation of any federal, state, or other governmental law, statute, regulation, or ordinance, except as provided in Section 10.2. 10.2 NON-COVERED CLAIMS. Claims arising out of the Business Protection Agreement and workers' compensation or unemployment compensation benefits are not covered by this Section 10. Non-covered claims include but are not limited to claims by the Company for injunctive and/or other equitable relief for unfair competition and/or the use and/or unauthorized disclosure of trade secrets or confidential information, as to which Employee understands and agrees that the Company may seek and obtain relief from a court of competent jurisdiction. -5-

10.3 REQUIRED NOTICE OF ALL CLAIMS AND STATUTE OF LIMITATIONS. Company and Employee agree that the aggrieved party must give written notice of any claim to the other party within one year of the date the aggrieved party first has knowledge of the event giving rise to the claim; otherwise the claim shall be void and deemed waived even if there is a federal or state statute of limitations which would have given more time to pursue the claim. The written notice shall identify and describe the nature of all claims asserted and the facts upon which such claims are based. 10.4 ARBITRATION PROCEDURES. Any arbitration shall be conducted in accordance with the then-current Model Employment Arbitration Procedures of the American Arbitration Association ("AAA"), modified to substitute for AAA actions, the United States Arbitration and Mediation Service ("USA&MS"), before an arbitrator who is licensed to practice law in the state of Pennsylvania (the "Arbitrator"). The arbitration shall take place in or near Bethlehem, Pennsylvania. 10.4.1 SELECTION OF ARBITRATOR. The USA&MS shall give each party a list of 11 arbitrators drawn from its panel of labor-management dispute arbitrators. Each party may strike all names on the list it deems unacceptable. If only one common name remains on the lists of all parties, that individual shall be designated as the Arbitrator. If more than one common name remains on the lists of all parties, the parties shall strike names alternately until only one remains. The party who did not initiate the claim shall strike first. If no common name remains on the lists of all parties, the USA&MS shall furnish an additional list or lists until an Arbitrator is selected. 10.4.2 APPLICABLE LAW. The Arbitrator shall apply the substantive law (and the law of remedies, if applicable) specified in this Agreement or federal law, or both, as applicable to the claim(s) asserted. The Arbitrator, and not any federal, state, or local court or agency, shall have exclusive authority to resolve any dispute relating to the interpretation, applicability, enforceability or formation of this Agreement, including but not limited to any claim that all or any part of this Agreement is void or voidable. The arbitration shall be final and binding upon the parties, except as provided in this Agreement. 10.4.3 AUTHORITY. The Arbitrator shall have jurisdiction to hear and rule on pre-hearing disputes and is authorized to hold pre-hearing conferences by telephone or in person as the Arbitrator deems necessary. The Arbitrator shall have the authority to entertain a motion to dismiss and/or a motion for summary judgment by any party and shall apply the standards governing such motions under the Federal Rules of Civil Procedure. The Arbitrator shall render an award and opinion in the form typically rendered in labor arbitrations. 10.4.4 REPRESENTATION. Any party may be represented by an attorney or other representative selected by the party. 10.4.5 DISCOVERY. Each party shall have the right to take the deposition of one individual and any expert witness designated by another party. Each party also shall have the right to make requests for production of documents to any party. The subpoena right specified below shall be applicable to discovery pursuant to this paragraph. Additional discovery may be had only where the Arbitrator selected pursuant to this Agreement so orders, -6-

upon a showing of substantial need. At least 30 days before the arbitration, the parties must exchange lists of witnesses, including any experts, and copies of all exhibits intended to be used at the arbitration. Each party shall have the right to subpoena witnesses and documents for the arbitration. 10.4.6 REPORTER. Either party, at its expense, may arrange for and pay the cost of a court reporter to provide a stenographic record of proceedings. 10.4.7 POST-HEARING BRIEFS. Either party, upon request at the close of hearing, shall be given leave to file a post-hearing brief. The time for filing such a brief shall be set by the Arbitrator. 10.5 ENFORCEMENT. Either party may bring an action in any court of competent jurisdiction to compel arbitration under this Agreement and to enforce an arbitration award. Except as otherwise provided in this Agreement, both the Company and Employee agree that neither shall initiate or prosecute any lawsuit (other than for a non-covered claim) in any way related to any claim covered by this Agreement. A party opposing enforcement of an award may not do so in an enforcement proceeding, but must bring a separate action in any court of competent jurisdiction to set aside the award, where the standard of review will be the same as that applied by an appellate court reviewing a decision of a trial court sitting without a jury. 10.6 ARBITRATION FEES AND COSTS. Company and Employee shall equally share the fees and costs of the Arbitrator. Each party will deposit funds or post other appropriate security for its share of the Arbitrator's fee, in an amount and manner determined by the Arbitrator, 10 days before the first day of hearing. Each party shall pay for its own costs and attorneys' fees, if any, provided that the Arbitrator, in its sole discretion, may award reasonable fees to the prevailing party in a proceeding. 11. GENERAL TERMS AND CONDITIONS. This Agreement constitutes the entire understanding of the parties relating to the employment of Employee by the Company, and supersedes and replaces all written and oral agreements heretofore made or existing by and between the parties relating thereto. This Agreement shall be construed in accordance with the laws of the state of Pennsylvania, without regard to any contrary conflicts of laws rules thereof. This Agreement shall inure to the benefit of any successors or assigns of the Company. All captions used herein are intended solely for convenience of reference and shall in no way limit any of the provisions of this Agreement. Employee acknowledges that he signed this Agreement upon his initial employment with the Company. The parties have executed this Employment Agreement as of the date stated above.

Employee may terminate his employment under this Agreement by 60 days' written notice to the Company. 6.3 TERMINATION BY THE COMPANY FOR CAUSE. Employee's employment under this Agreement may be terminated by the Company at any time for cause. Only the following actions, failures, or events by or affecting Employee shall constitute "cause" for termination of Employee by the Company: (i) willful and continued failure by Employee to substantially perform his duties provided herein after a written demand for substantial performance is delivered to Employee by the chairman of the board of the Company, which demand identifies with reasonable specificity the manner in which Employee has not substantially performed his duties, and Employee's failure to comply with such demand within a reasonable time; (ii) the engaging by Employee in gross misconduct or gross negligence materially injurious to the Company; (iii) the commission of any act in direct competition with or materially detrimental to the best interests of the Company; or (iv) Employee's conviction of having committed a felony.

The findings of the board of directors shall not be binding on the arbitrators or other finders of fact in connection with any litigation or dispute arising out of this Agreement. 6.4 TERMINATION BY THE COMPANY WITHOUT CAUSE. The Company may terminate Employee's employment under this Agreement without cause by written notice to Employee.

provided that, without limitation, such a change of control shall be deemed to have occurred at such time as (i) any Acquiring Person hereafter becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of 30 percent or more of the combined voting power of Voting Securities; (ii) during any period of 12 consecutive calendar months, individuals who at the beginning of such period constitute the board of directors cease for any reason to constitute at least a majority thereof unless the election, or the nomination for election, by the Company's shareholders of each new director was approved by a vote of at least a majority of the directors then still in office who were directors at the beginning of the period; (iii) there shall be consummated (a) any consolidation or merger of the Company in which the Company is not the continuing or surviving corporation or pursuant to which Voting Securities would be converted into cash, securities, or other property, other than a merger of the Company in which the holders of Voting Securities immediately prior to the merger have the same, or substantially the same, proportionate ownership of common stock of the surviving corporation immediately after the merger, or (b) any sale, lease, exchange, or other transfer (in one transaction or a series of related transactions) of all, or substantially all, of the assets of the Company; or (iv) approval by the shareholders of the Company of any plan or proposal for the liquidation or dissolution of the Company. For purposes of this Agreement, "Acquiring Person" means any person or related persons which constitute a "group" for purposes of Section 13(d) and Rule 13d-5 under the Exchange Act, as such Section and Rule are in effect as of the date of this Agreement; provided, however, that the term Acquiring Person shall not include: (i) the Company or any of its subsidiaries; (ii) any employee benefit plan of the Company or any of its subsidiaries; (iii) any entity holding voting capital stock of the Company for or pursuant to the terms of any such employee benefit plan; or (iv) any person or group solely because such person or group has voting power with respect to capital stock of the Company arising from a revocable proxy or consent given in response to a public proxy or consent solicitation made pursuant to the Exchange Act. For purposes of this Agreement, "Voting Securities" means the Company's issued and outstanding securities ordinarily having the right to vote at elections for the Company's board of directors. 6.5 COMPENSATION UPON TERMINATION. 6.5.1 TERMINATION UNDER SECTIONS 6.1, 6.2, OR 6.3. In the event of a termination of Employee's employment under Sections 6.1, 6.2, or 6.3, Employee's regular compensation pursuant to Section 3.1 shall be prorated and payable until the date of termination and Employee shall be paid any bonus that has been approved but not yet paid. 6.5.2 TERMINATION UNDER SECTION 6.4. In the event of a termination of Employee's employment by the Company without cause as provided in Section 6.4, Employee shall continue to be paid the salary provided in Section 3.1 for the greater of (a) 12 months, (b) the remaining term of this Agreement, or (c) 24 months if Employee elects to treat an event described in Section 6.4.3 as a termination without cause, from the date of notice of such termination of employment or the date of such event, in the manner and at the times at which regular compensation was paid to Employee during the term of his employment under this Agreement, except that if Employee elects to treat an event described in Sections 6.4.1, 6.4.2, or 6.4.3 as a termination without cause but continues to work for the Company or any of its subsidiaries, then any amounts Employee receives as compensation following the event shall be credited against the amounts payable to Employee under this section. In no other respect -4-

shall the amount of any payment provided for in this section be reduced by any compensation or benefits earned by employee as a result of employment after his termination. As a condition to receipt of the compensation described in the first sentence of this Section 6.5.2, Employee shall sign and deliver a release agreement, in form and substance satisfactory to the Company and Employee, releasing all claims related to Employee's employment. The Company's obligation to pay the amounts stated in this section shall terminate if Employee fails to comply with the Business Protection Agreement within the applicable time period stated in the first sentence of this section. 7. REMEDIES. The respective rights and duties of the Company and Employee under this Agreement are in addition to, and not in lieu of, those rights and duties afforded to and imposed upon them by law or at equity. 8. SEVERABILITY OF PROVISIONS. The provisions of this Agreement are severable, and if any provision hereof is held invalid or unenforceable, it shall be enforced to the maximum extent permissible, and the remaining provisions of the Agreement shall continue in full force and effect. 9. NONWAIVER. Failure by either party at any time to require performance of any provision of this Agreement shall not limit the right of the party failing to require performance to enforce the provision. No provision of this Agreement may be waived by either party except by a writing signed by that party. A waiver of any breach of a provision of this Agreement shall be construed narrowly and shall not be deemed to be a waiver of any succeeding breach of that provision or a waiver of that provision itself or of any other provision. 10. ARBITRATION. 10.1 CLAIMS COVERED. All claims or controversies, except for those excluded by Section 10.2 ("claims"), whether or not arising out of Employee's employment (or its termination), that the Company may have against the Employee or that Employee may have against the Company or against its officers, directors, employees or agents, in their capacity as such or otherwise, shall be resolved as provided in this Section 10. Claims covered by this Section 10 include, but are not limited to, claims for wages or other compensation due; claims for breach of any contract or covenant (express or implied); tort claims; claims for discrimination (including, but not limited to, race, sex, sexual orientation, religion, national origin, age, marital status, or disability); claims for benefits (except where an employee benefit or pension plan specifies that its claims procedure shall culminate in an arbitration procedure different from this one), and claims for violation of any federal, state, or other governmental law, statute, regulation, or ordinance, except as provided in Section 10.2. 10.2 NON-COVERED CLAIMS. Claims arising out of the Business Protection Agreement and workers' compensation or unemployment compensation benefits are not covered by this Section 10. Non-covered claims include but are not limited to claims by the Company for injunctive and/or other equitable relief for unfair competition and/or the use and/or unauthorized disclosure of trade secrets or confidential information, as to which Employee understands and agrees that the Company may seek and obtain relief from a court of competent jurisdiction. -5-

10.3 REQUIRED NOTICE OF ALL CLAIMS AND STATUTE OF LIMITATIONS. Company and Employee agree that the aggrieved party must give written notice of any claim to the other party within one year of the date the aggrieved party first has knowledge of the event giving rise to the claim; otherwise the claim shall be void and deemed waived even if there is a federal or state statute of limitations which would have given more time to pursue the claim. The written notice shall identify and describe the nature of all claims asserted and the facts upon which such claims are based. 10.4 ARBITRATION PROCEDURES. Any arbitration shall be conducted in accordance with the then-current Model Employment Arbitration Procedures of the American Arbitration Association ("AAA"), modified to substitute for AAA actions, the United States Arbitration and Mediation Service ("USA&MS"), before an arbitrator who is licensed to practice law in the state of Pennsylvania (the "Arbitrator"). The arbitration shall take place in or near Bethlehem, Pennsylvania. 10.4.1 SELECTION OF ARBITRATOR. The USA&MS shall give each party a list of 11 arbitrators drawn from its panel of labor-management dispute arbitrators. Each party may strike all names on the list it deems unacceptable. If only one common name remains on the lists of all parties, that individual shall be designated as the Arbitrator. If more than one common name remains on the lists of all parties, the parties shall strike names alternately until only one remains. The party who did not initiate the claim shall strike first. If no common name remains on the lists of all parties, the USA&MS shall furnish an additional list or lists until an Arbitrator is selected. 10.4.2 APPLICABLE LAW. The Arbitrator shall apply the substantive law (and the law of remedies, if applicable) specified in this Agreement or federal law, or both, as applicable to the claim(s) asserted. The Arbitrator, and not any federal, state, or local court or agency, shall have exclusive authority to resolve any dispute relating to the interpretation, applicability, enforceability or formation of this Agreement, including but not limited to any claim that all or any part of this Agreement is void or voidable. The arbitration shall be final and binding upon the parties, except as provided in this Agreement. 10.4.3 AUTHORITY. The Arbitrator shall have jurisdiction to hear and rule on pre-hearing disputes and is authorized to hold pre-hearing conferences by telephone or in person as the Arbitrator deems necessary. The Arbitrator shall have the authority to entertain a motion to dismiss and/or a motion for summary judgment by any party and shall apply the standards governing such motions under the Federal Rules of Civil Procedure. The Arbitrator shall render an award and opinion in the form typically rendered in labor arbitrations. 10.4.4 REPRESENTATION. Any party may be represented by an attorney or other representative selected by the party. 10.4.5 DISCOVERY. Each party shall have the right to take the deposition of one individual and any expert witness designated by another party. Each party also shall have the right to make requests for production of documents to any party. The subpoena right specified below shall be applicable to discovery pursuant to this paragraph. Additional discovery may be had only where the Arbitrator selected pursuant to this Agreement so orders, -6-

upon a showing of substantial need. At least 30 days before the arbitration, the parties must exchange lists of witnesses, including any experts, and copies of all exhibits intended to be used at the arbitration. Each party shall have the right to subpoena witnesses and documents for the arbitration. 10.4.6 REPORTER. Either party, at its expense, may arrange for and pay the cost of a court reporter to provide a stenographic record of proceedings. 10.4.7 POST-HEARING BRIEFS. Either party, upon request at the close of hearing, shall be given leave to file a post-hearing brief. The time for filing such a brief shall be set by the Arbitrator. 10.5 ENFORCEMENT. Either party may bring an action in any court of competent jurisdiction to compel arbitration under this Agreement and to enforce an arbitration award. Except as otherwise provided in this Agreement, both the Company and Employee agree that neither shall initiate or prosecute any lawsuit (other than for a non-covered claim) in any way related to any claim covered by this Agreement. A party opposing enforcement of an award may not do so in an enforcement proceeding, but must bring a separate action in any court of competent jurisdiction to set aside the award, where the standard of review will be the same as that applied by an appellate court reviewing a decision of a trial court sitting without a jury. 10.6 ARBITRATION FEES AND COSTS. Company and Employee shall equally share the fees and costs of the Arbitrator. Each party will deposit funds or post other appropriate security for its share of the Arbitrator's fee, in an amount and manner determined by the Arbitrator, 10 days before the first day of hearing. Each party shall pay for its own costs and attorneys' fees, if any, provided that the Arbitrator, in its sole discretion, may award reasonable fees to the prevailing party in a proceeding. 11. GENERAL TERMS AND CONDITIONS. This Agreement constitutes the entire understanding of the parties relating to the employment of Employee by the Company, and supersedes and replaces all written and oral agreements heretofore made or existing by and between the parties relating thereto. This Agreement shall be construed in accordance with the laws of the state of Pennsylvania, without regard to any contrary conflicts of laws rules thereof. This Agreement shall inure to the benefit of any successors or assigns of the Company. All captions used herein are intended solely for convenience of reference and shall in no way limit any of the provisions of this Agreement.

provided that, without limitation, such a change of control shall be deemed to have occurred at such time as (i) any Acquiring Person hereafter becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of 30 percent or more of the combined voting power of Voting Securities; (ii) during any period of 12 consecutive calendar months, individuals who at the beginning of such period constitute the board of directors cease for any reason to constitute at least a majority thereof unless the election, or the nomination for election, by the Company's shareholders of each new director was approved by a vote of at least a majority of the directors then still in office who were directors at the beginning of the period; (iii) there shall be consummated (a) any consolidation or merger of the Company in which the Company is not the continuing or surviving corporation or pursuant to which Voting Securities would be converted into cash, securities, or other property, other than a merger of the Company in which the holders of Voting Securities immediately prior to the merger have the same, or substantially the same, proportionate ownership of common stock of the surviving corporation immediately after the merger, or (b) any sale, lease, exchange, or other transfer (in one transaction or a series of related transactions) of all, or substantially all, of the assets of the Company; or (iv) approval by the shareholders of the Company of any plan or proposal for the liquidation or dissolution of the Company.

For purposes of this Agreement, "Voting Securities" means the Company's issued and outstanding securities ordinarily having the right to vote at elections for the Company's board of directors. 6.5 COMPENSATION UPON TERMINATION. 6.5.1 TERMINATION UNDER SECTIONS 6.1, 6.2, OR 6.3. In the event of a termination of Employee's employment under Sections 6.1, 6.2, or 6.3, Employee's regular compensation pursuant to Section 3.1 shall be prorated and payable until the date of termination and Employee shall be paid any bonus that has been approved but not yet paid. 6.5.2 TERMINATION UNDER SECTION 6.4. In the event of a termination of Employee's employment by the Company without cause as provided in Section 6.4, Employee shall continue to be paid the salary provided in Section 3.1 for the greater of (a) 12 months, (b) the remaining term of this Agreement, or (c) 24 months if Employee elects to treat an event described in Section 6.4.3 as a termination without cause, from the date of notice of such termination of employment or the date of such event, in the manner and at the times at which regular compensation was paid to Employee during the term of his employment under this Agreement, except that if Employee elects to treat an event described in Sections 6.4.1, 6.4.2, or 6.4.3 as a termination without cause but continues to work for the Company or any of its subsidiaries, then any amounts Employee receives as compensation following the event shall be credited against the amounts payable to Employee under this section. In no other respect -4-

shall the amount of any payment provided for in this section be reduced by any compensation or benefits earned by employee as a result of employment after his termination. As a condition to receipt of the compensation described in the first sentence of this Section 6.5.2, Employee shall sign and deliver a release agreement, in form and substance satisfactory to the Company and Employee, releasing all claims related to Employee's employment. The Company's obligation to pay the amounts stated in this section shall terminate if Employee fails to comply with the Business Protection Agreement within the applicable time period stated in the first sentence of this section. 7. REMEDIES. The respective rights and duties of the Company and Employee under this Agreement are in addition to, and not in lieu of, those rights and duties afforded to and imposed upon them by law or at equity. 8. SEVERABILITY OF PROVISIONS. The provisions of this Agreement are severable, and if any provision hereof is held invalid or unenforceable, it shall be enforced to the maximum extent permissible, and the remaining provisions of the Agreement shall continue in full force and effect. 9. NONWAIVER. Failure by either party at any time to require performance of any provision of this Agreement shall not limit the right of the party failing to require performance to enforce the provision. No provision of this Agreement may be waived by either party except by a writing signed by that party. A waiver of any breach of a provision of this Agreement shall be construed narrowly and shall not be deemed to be a waiver of any succeeding breach of that provision or a waiver of that provision itself or of any other provision. 10. ARBITRATION. 10.1 CLAIMS COVERED. All claims or controversies, except for those excluded by Section 10.2 ("claims"), whether or not arising out of Employee's employment (or its termination), that the Company may have against the Employee or that Employee may have against the Company or against its officers, directors, employees or agents, in their capacity as such or otherwise, shall be resolved as provided in this Section 10. Claims covered by this Section 10 include, but are not limited to, claims for wages or other compensation due; claims for breach of any contract or covenant (express or implied); tort claims; claims for discrimination (including, but not limited to, race, sex, sexual orientation, religion, national origin, age, marital status, or disability); claims for benefits (except where an employee benefit or pension plan specifies that its claims procedure shall culminate in an arbitration procedure different from this one), and claims for violation of any federal, state, or other governmental law, statute, regulation, or ordinance, except as provided in Section 10.2. 10.2 NON-COVERED CLAIMS. Claims arising out of the Business Protection Agreement and workers' compensation or unemployment compensation benefits are not covered by this Section 10. Non-covered claims include but are not limited to claims by the Company for injunctive and/or other equitable relief for unfair competition and/or the use and/or unauthorized disclosure of trade secrets or confidential information, as to which Employee understands and agrees that the Company may seek and obtain relief from a court of competent jurisdiction. -5-

10.3 REQUIRED NOTICE OF ALL CLAIMS AND STATUTE OF LIMITATIONS. Company and Employee agree that the aggrieved party must give written notice of any claim to the other party within one year of the date the aggrieved party first has knowledge of the event giving rise to the claim; otherwise the claim shall be void and deemed waived even if there is a federal or state statute of limitations which would have given more time to pursue the claim. The written notice shall identify and describe the nature of all claims asserted and the facts upon which such claims are based. 10.4 ARBITRATION PROCEDURES. Any arbitration shall be conducted in accordance with the then-current Model Employment Arbitration Procedures of the American Arbitration Association ("AAA"), modified to substitute for AAA actions, the United States Arbitration and Mediation Service ("USA&MS"), before an arbitrator who is licensed to practice law in the state of Pennsylvania (the "Arbitrator"). The arbitration shall take place in or near Bethlehem, Pennsylvania. 10.4.1 SELECTION OF ARBITRATOR. The USA&MS shall give each party a list of 11 arbitrators drawn from its panel of labor-management dispute arbitrators. Each party may strike all names on the list it deems unacceptable. If only one common name remains on the lists of all parties, that individual shall be designated as the Arbitrator. If more than one common name remains on the lists of all parties, the parties shall strike names alternately until only one remains. The party who did not initiate the claim shall strike first. If no common name remains on the lists of all parties, the USA&MS shall furnish an additional list or lists until an Arbitrator is selected. 10.4.2 APPLICABLE LAW. The Arbitrator shall apply the substantive law (and the law of remedies, if applicable) specified in this Agreement or federal law, or both, as applicable to the claim(s) asserted. The Arbitrator, and not any federal, state, or local court or agency, shall have exclusive authority to resolve any dispute relating to the interpretation, applicability, enforceability or formation of this Agreement, including but not limited to any claim that all or any part of this Agreement is void or voidable. The arbitration shall be final and binding upon the parties, except as provided in this Agreement. 10.4.3 AUTHORITY. The Arbitrator shall have jurisdiction to hear and rule on pre-hearing disputes and is authorized to hold pre-hearing conferences by telephone or in person as the Arbitrator deems necessary. The Arbitrator shall have the authority to entertain a motion to dismiss and/or a motion for summary judgment by any party and shall apply the standards governing such motions under the Federal Rules of Civil Procedure. The Arbitrator shall render an award and opinion in the form typically rendered in labor arbitrations. 10.4.4 REPRESENTATION. Any party may be represented by an attorney or other representative selected by the party. 10.4.5 DISCOVERY. Each party shall have the right to take the deposition of one individual and any expert witness designated by another party. Each party also shall have the right to make requests for production of documents to any party. The subpoena right specified below shall be applicable to discovery pursuant to this paragraph. Additional discovery may be had only where the Arbitrator selected pursuant to this Agreement so orders, -6-

upon a showing of substantial need. At least 30 days before the arbitration, the parties must exchange lists of witnesses, including any experts, and copies of all exhibits intended to be used at the arbitration. Each party shall have the right to subpoena witnesses and documents for the arbitration. 10.4.6 REPORTER. Either party, at its expense, may arrange for and pay the cost of a court reporter to provide a stenographic record of proceedings. 10.4.7 POST-HEARING BRIEFS. Either party, upon request at the close of hearing, shall be given leave to file a post-hearing brief. The time for filing such a brief shall be set by the Arbitrator. 10.5 ENFORCEMENT. Either party may bring an action in any court of competent jurisdiction to compel arbitration under this Agreement and to enforce an arbitration award. Except as otherwise provided in this Agreement, both the Company and Employee agree that neither shall initiate or prosecute any lawsuit (other than for a non-covered claim) in any way related to any claim covered by this Agreement. A party opposing enforcement of an award may not do so in an enforcement proceeding, but must bring a separate action in any court of competent jurisdiction to set aside the award, where the standard of review will be the same as that applied by an appellate court reviewing a decision of a trial court sitting without a jury. 10.6 ARBITRATION FEES AND COSTS. Company and Employee shall equally share the fees and costs of the Arbitrator. Each party will deposit funds or post other appropriate security for its share of the Arbitrator's fee, in an amount and manner determined by the Arbitrator, 10 days before the first day of hearing. Each party shall pay for its own costs and attorneys' fees, if any, provided that the Arbitrator, in its sole discretion, may award reasonable fees to the prevailing party in a proceeding. 11. GENERAL TERMS AND CONDITIONS. This Agreement constitutes the entire understanding of the parties relating to the employment of Employee by the Company, and supersedes and replaces all written and oral agreements heretofore made or existing by and between the parties relating thereto. This Agreement shall be construed in accordance with the laws of the state of Pennsylvania, without regard to any contrary conflicts of laws rules thereof. This Agreement shall inure to the benefit of any successors or assigns of the Company. All captions used herein are intended solely for convenience of reference and shall in no way limit any of the provisions of this Agreement. Employee acknowledges that he signed this Agreement upon his initial employment with the Company. The parties have executed this Employment Agreement as of the date stated above.

Company and Employee agree that the aggrieved party must give written notice of any claim to the other party within one year of the date the aggrieved party first has knowledge of the event giving rise to the claim; otherwise the claim shall be void and deemed waived even if there is a federal or state statute of limitations which would have given more time to pursue the claim. The written notice shall identify and describe the nature of all claims asserted and the facts upon which such claims are based. 10.4 ARBITRATION PROCEDURES. Any arbitration shall be conducted in accordance with the then-current Model Employment Arbitration Procedures of the American Arbitration Association ("AAA"), modified to substitute for AAA actions, the United States Arbitration and Mediation Service ("USA&MS"), before an arbitrator who is licensed to practice law in the state of Pennsylvania (the "Arbitrator").

If no common name remains on the lists of all parties, the USA&MS shall furnish an additional list or lists until an Arbitrator is selected. -6-

10.4.2 APPLICABLE LAW.

The Arbitrator shall render an award and opinion in the form typically rendered in labor arbitrations. 10.4.4 REPRESENTATION. Any party may be represented by an attorney or other representative selected by the party. 10.4.5 DISCOVERY. Each party shall have the right to take the deposition of one individual and any expert witness designated by another party.

Additional discovery may be had only where the Arbitrator selected pursuant to this Agreement so orders, upon a showing of substantial need. At least 30 days before the arbitration, the parties must exchange lists of witnesses, including any experts, and copies of all exhibits intended to be used at the arbitration. Each party shall have the right to subpoena witnesses and documents for the arbitration. 10.4.6 REPORTER.

Except as otherwise provided in this Agreement, both the Company and Employee agree that neither shall initiate or prosecute any lawsuit (other than for a non-covered claim) in any way related to any claim covered by this Agreement. A party opposing enforcement of an award may not do so in an enforcement proceeding, but must bring a separate action in any court of competent jurisdiction to set aside the award, where the standard of review will be the same as that applied by an appellate court reviewing a decision of a trial court sitting without a jury. -7-

payable  quarterly  in  advance as  compensation  for  service on the Board.  No
additional  fee is paid for service on any  committee of the Board.  Nonemployee
Directors  also receive a grant of 40,000  stock  options upon joining the Board
and a grant of 20,000 stock  options each year  thereafter  on the annual option
grant date for officers and  employees  of the Company.  The options  granted to
nonemployee  Directors are nonqualified stock options, the exercise price of the
options is the mean between the high and low sale prices of the Company's Common
Stock as quoted on The Nasdaq Stock  Market on the grant date,  the options vest
over a four-year  period  with  one-fourth  of each option  vesting on the first
anniversary of the grant date and the remainder  vesting on a monthly basis over
the next three  years.  All vesting of the options  will cease 90 days after the
nonemployee Director ceases to serve on the Board. Options become exercisable in
full  immediately  upon the occurrence of a change in control of the Company.  A
change in control of the Company  would occur on the happening of such events as
the  beneficial  ownership  by a person  or group of 30  percent  or more of the
outstanding  Common  Stock,  certain  changes in Board  membership  affecting  a
majority  of  positions,  certain  mergers  or  consolidations,  a sale or other
transfer of all or substantially  all the Company's  assets,  or approval by the
shareholders of a plan of liquidation or dissolution of the Company,  as well as
any change in control  required to be reported by the proxy  disclosure rules of
the  Securities  and Exchange  Commission.  Payment of the exercise price may be
made in cash or by delivery of previously acquired shares of Common Stock having
a fair market value equal to the aggregate exercise price.

Options Awarded from the Pool may be either Incentive Stock Options or non-qualified stock options, as determined by the Board. If an Option should expire or become unexercisable for any reason without having been exercised in full, or, if Shares are subsequently repurchased by the Company, the unpurchased or repurchased Shares which were subject thereto shall, unless the Plan shall have been terminated, return to the Plan and become available for future Award under the Plan. Section 7. Terms and Conditions of Options. ------------------------------- Each Option Awarded pursuant to the Plan shall be authorized by the Board and shall be evidenced by an Option Agreement in such form as the Board may from time to time determine. Each Option Agreement shall incorporate by reference all other terms and conditions of the Plan, including the following terms and conditions: (1) Number of Shares. The number of Shares subject to the Option, which may include fractional Shares. (2) Option Price. The price per Share payable on the exercise of any Option which is an Incentive Stock Option shall be stated in the Option Agreement and shall be no less than the Fair Market Value per share of the Common Stock on the date such Option is Awarded, -9-

without regard to any restriction other than a restriction which will never lapse. Notwithstanding the foregoing, if an Option which is an Incentive Stock Option shall be Awarded under this Plan to any Employee who, at the time of the Award of such Option, owns stock possessing more than 10% of the total combined voting power of all classes of the stock of the Company (or its Parent or Subsidiaries), the price per Share payable upon exercise of such Option shall be no less than 110 percent (110%) of the Fair Market Value of the stock on the date such Option is Awarded. The price per Share payable on the exercise of an Option which is a non-qualified stock option shall be at least $.01 per Share and shall be stated in the Option Agreement. (3) Consideration. The consideration to be paid for the Shares to be issued upon the exercise of an Option, including the method of payment, shall be determined by the Board and may consist entirely of cash, check, promissory notes or shares of Common Stock having a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised, or any combination of such methods of payment, or such other consideration and method of payment permitted under any laws to which the Company is subject and which is approved by the Board. In making its determination as to the type of consideration to accept, the Board shall consider if acceptance of such consideration may be reasonably expected to benefit the Company. (1) If the consideration for the exercise of an Option is a promissory note, it shall bear interest at a per annum rate which is not less than the applicable federal rate determined in accordance with Section 1274(d) of the Code as of the date of exercise. In such an instance the Company may retain the Shares purchased upon the exercise of the Option in escrow as security for payment of the promissory note. -10-

(2) If the consideration for the exercise of an Option is the surrender of previously acquired and owned shares of Common Stock, the Optionee will be required to make representations and warranties satisfactory to the Company regarding his title to the shares of Common Stock used to effect the purchase, including without limitation, representations and warranties that the Optionee has good and marketable title to such shares of Common Stock free and clear of any and all liens, encumbrances, charges, equities, claims, security interests, options or restrictions, and has full power to deliver such shares of Common Stock without obtaining the consent or approval of any person or governmental authority other than those which have already given consent or approval in a manner satisfactory to the Company. The value of the shares of Common Stock used to effect the purchase shall be the Fair Market Value of such shares of Common Stock on the date of exercise as determined by the Board in its sole discretion, exercised in good faith. (4) Form of Option. The OptionAgreement will state whether the Option Awarded is an Incentive Stock Option or a non-qualified stock Option, and will constitute a binding determination as to the form of Option Awarded. (5) Exercise of Options. Any Option Awarded hereunder shall be exercisable at such times and under such conditions as may be determined by the Board and as shall be permissible under the terms of the Plan, including performance criteria with respect to the Company and/or the Optionee, and as shall be permissible under the terms of the Plan. An Option may be exercised in accordance with the provisions of this Plan as to all or any portion of the Shares then exercisable under an Option from time to time during the term of the Option. An Option may not be exercised solely for a fraction of a Share. -11-

An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company at its principal executive office in accordance with the terms of the Option Agreement by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company, accompanied by an executed Stock Purchase Agreement and any other agreements required by the terms of the Plan and/or Option Agreement. Full payment may consist of such consideration and method of payment allowable under Section 7 of the Plan. No adjustment shall be made for a dividend or other right for which the record date is prior to the date the Option is exercised, except as provided in Section 9 of the Plan. As soon as practicable after any proper exercise of an Option in accordance with the provisions of the Plan, the Company shall, without transfer or issue tax to the Optionee, deliver to the Optionee at the principal executive office of the Company or such other place as shall be mutually agreed upon between the Company and the Optionee, a certificate or certificates representing the Shares for which the Option shall have been exercised. The time of issuance and delivery of the certificate(s) representing the Shares for which the Option shall have been exercised may be postponed by the Company for such period as may be required by the Company, with reasonable diligence, to comply with any applicable listing requirements of any national or regional securities exchange or any law or regulation applicable to the issuance or delivery of such Shares. Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be available, both for Award under the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. -12-

(6) Term and Vesting of Options. --------------------------- (1) Notwithstanding any other provision of this Plan, no Option shall be (A) Awarded under this Plan after ten (10) years from the date on which this Plan is adopted by the Board, or (B) exercisable more than ten (10) years from the date of Award; provided, however, that if an Incentive Stock Option shall be Awarded under this Plan to any Employee who, at the time of the Award of such Option, owns stock possessing more than 10% of the total combined voting power for all classes of the stock of he Company (or its Parent or Subsidiaries), the foregoing clause (B) shall be deemed modified by substituting "five (5) years" for the term "ten (10) years" that appears therein. (2) No Option Awarded to any Optionee shall be treated as an Incentive Stock Option, to the extent such Option would cause the aggregate Fair Market Value of all Shares with respect to which Incentive Stock Options are exercisable by such Optionee for the first time during any calendar year (determined as of the date of Award of each such Option) to exceed $100,000. For purposes of determining whether an Incentive Stock Option would cause such aggregate Fair Market Value to exceed the $100,000 limitation, such Incentive Stock Options shall be taken into account in the order Awarded. For purposes of this subsection, Incentive Stock Options include all incentive stock options under all plans of the Company and its Parent and Subsidiaries that are incentive stock option plans within the meaning of Section 422 of the Code. Options Awarded hereunder shall mature and become exercisable in whole or in part, in accordance with such vesting schedule as the Board shall determine, which schedule shall be stated in the Option Agreement. Options may be exercised in any order elected by the -13-

Optionee whether or not the Optionee holds any unexercised Options under this Plan or any other plan of the Company. (7) Termination of Options. ---------------------- (1) Unless sooner terminated as provided in this Plan, each Option shall be exercisable for the period of time as shall be determined by the Board and set forth in the Option Agreement, and shall be void and unexercisable thereafter. (i) Except as otherwise provided herein or in the Option Agreement, upon the termination of the Optionee's employment or other relationship with the Company for any reason, Options exercisable on the date of termination of employment or such other relationship shall be exercisable by the Optionee (or in the case of the Optionee's death subsequent to termination of employment or such other relationship, by the Optionee's executor(s) or administrator(s)) for a period of three (3) months from the date of the Optionee's termination of employment or such other relationship. (2) Upon the Disability or death of an Optionee while in the employ of or engagement by the Company, Options held by such Optionee which are exercisable on the date of Disability or death shall be exercisable for a period of twelve (12) months commencing on the date of the Optionee's Disability or death, by the Optionee or his legal guardian or representative or, in the case of death, by his executor(s) or administrator(s); provided, however, that if such disabled Optionee shall commence any employment or engagement during such one (1) year period with or by a competitor of the Company (including, but not limited to, full or part-time employment or independent consulting work), as determined solely in the judgment of -14-

the Board, all Options held by such Optionee which have not yet been exercised shall terminate immediately upon the commencement thereof. (3) Options may be terminated at any time by agreement between the Company and the Optionee. (8) Forfeiture. Notwithstanding any other provision of this Plan, if the Optionee's employment or engagement is terminated for "cause" (as such term is defined in the Optionee's employment agreement or invention and non-disclosure agreement with the Company, but if the Optionee is not a party to any such agreement, then, as such term is defined in the Stock Purchase Agreement) or if the Board makes a determination that the Optionee (i) has engaged in any type of disloyalty to the Company, including without limitation, fraud, embezzlement, theft, or dishonesty in the course of his employment or engagement, or (ii) has been convicted of a felony or (iii) has disclosed trade secrets or confidential information of the Company or (iv) has breached any agreement with or duty to the Company in respect of confidentiality, non-disclosure, non-competition or otherwise, all unexercised Options shall terminate upon the earlier of the date of termination of employment or engagement for "cause" or the date of such a finding. In the event of such a finding, in addition to immediate termination of all unexercised Options, the Optionee shall forfeit all Shares for which the Company has not yet delivered share certificates to the Optionee and the Company shall refund to the Optionee the Option purchase price paid to it. Notwithstanding anything herein to the contrary, the Company may withhold delivery of share certificates pending the resolution of any inquiry that could lead to a finding resulting in forfeiture. Section 8. Determination of Fair Market Value of Common Stock. -------------------------------------------------- -15-

(1) Except to the extent otherwise provided in this Section 8, the Fair Market Value of a share of Common Stock shall be determined by the Board in its sole discretion. (2) Notwithstanding the provisions of Section 8(a), in the event that shares of Common Stock are traded in the over-the-counter market, the Fair Market Value of a share of Common Stock shall be the mean of the bid and asked prices for a share of Common Stock on the relevant valuation date as reported in The Wall Street Journal (or, if not so reported, as otherwise reported by the National Association of Securities Dealers Automated Quotations ("NASDAQ") System), as applicable or, if there is no trading on such date, on the next trading date. In the event shares of Common Stock are listed on a national or regional securities exchange or traded through NASDAQ/NMS, the Fair Market Value of a share of Common Stock shall be the closing price for a share of Common Stock on the exchange or on NASDAQ/NMS, as reported in The Wall Street Journal on the relevant valuation date, or if there is no trading on that date, on the next trading date. Section 9. Adjustments. ----------- (1) Subject to required action by the stockholders, if any, the number of Shares as to which Options may be Awarded under this Plan and the number of Shares subject to outstanding Options and the option prices thereof shall be adjusted proportionately for any increase or decrease in the number of outstanding shares of Common Stock of the Company resulting from stock splits, reverse stock splits, stock dividends, reclassifications and recapitalizations. (2) No fractional Shares shall be issuable on account of any action aforesaid, and the aggregate number of Shares into which Shares then covered by the Option, when -16-

changed as the result of such action, shall be reduced to the number of whole Shares resulting from such action, unless the Board, in its sole discretion, shall determine to issue scrip certificates in respect to any fractional Shares, which scrip certificates, in such event, shall be in a form and have such terms and conditions as the Board in its discretion shall prescribe. Section 10. Rights as a Stockholder. ----------------------- The Optionee shall have no rights as a stockholder of the Company and shall not have the right to vote nor receive dividends with respect to any Shares subject to an Option until such Option has been exercised and a certificate with respect to the Shares purchased upon such exercise has been issued to him. Section 11. Time of Awarding Options. ------------------------ The date of Award of an Option shall, for all purposes, be the date on which the Board makes the determination Awarding such Option.

Modification, Extension and Renewal of Option. --------------------------------------------- Subject to the terms and conditions of the Plan, the Board may modify, extend or renew an Option, or accept the surrender of an Option (to the extent not theretofore exercised). Notwithstanding the foregoing, (a) no modification of an Option which adversely affects the Optionee shall be made without the consent of the Optionee, and (b) no Incentive Stock Option may be modified, extended or renewed if such action would cause it to cease to be an "incentive stock option" within the meaning of Section 422 of the Code.

In addition, in the event of a Change in Control of the Company, the Board shall have the right, in its sole discretion, subject to and conditioned upon the consummation of the transactions which result in the Change in Control, to (1) arrange for the successor company (or other entity) to assume all of the rights and obligations of the Company under this Plan; or (2) terminate this Plan and (a) to pay to all Optionees cash with respect to those Options that are vested as of the date of such consummation in an amount equal to the difference between the exercise price and the Fair Market Value of a Share of Common Stock (determined as of the date the Plan is terminated) multiplied by the number of Options that are vested as of the date of the consummation of the transactions which result in the Change in Control which are held by the Optionee as of such date, or (b) to arrange -20-

for the exchange of all Options for options to purchase common stock in the successor corporation, or (c) to distribute to each Optionee other property in an amount equal to and in the same form as the Optionee would have received from the successor corporation if the Optionee had owned the Shares subject to Options that are vested as of the date of the consummation of the transactions which result in the Change in Control rather than the Option at the time of such consummation. The form of payment or distribution to the Optionee pursuant to this Section shall be determined by the Board in its sole discretion. Section 17. Amendment of the Plan. --------------------- Insofar as permitted by law and the Plan, the Board may from time to time suspend, terminate or discontinue the Plan or revise or amend it in any respect whatsoever with respect to any Shares at the time not subject to an Option; provided, however, that without approval of the stockholders, no such revision or amendment may change the aggregate number of Shares for which Options may be Awarded hereunder, change the designation of the class of Employees eligible to receive Options or decrease the price at which Options may be Awarded. Any other provision of this Section 17 notwithstanding (with the exception of Section 31 hereof), the Board specifically is authorized to adopt any amendment to this Plan deemed by the Board to be necessary or advisable to assure that the Incentive Stock Options or the non-qualified stock Options available under the Plan continue to be treated as such, respectively, under all applicable laws.

Application of Funds. -------------------- The proceeds received by the Company from the sale of Shares pursuant to the exercise of Options shall be used for general corporate purposes. -21-

Approval of Stockholders. ------------------------ This Plan shall become effective on the date that it is adopted by the Board; provided, however, that it shall become limited to a non-qualified stock option plan if it is not approved by the holders of a majority of the Company's outstanding voting stock within one year (365 days) of its adoption by the Board. The Board may Award Options hereunder prior to approval of the Plan or any material amendments thereto by the holders of a majority of the Company's outstanding voting stock; provided, however, that any and all Options so Awarded automatically shall be converted into non-qualified stock options if the Plan is not approved by such stockholders within 365 days of its adoption or material amendment. Section 21. Conditions Upon Issuance of Shares. ---------------------------------- (1) Options Awarded under the Plan are conditioned upon the Company obtaining any required permit or order from appropriate governmental agencies, authorizing the Company to issue such Options and Shares issuable upon the exercise thereof. (2) Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance. -22-

(3) As a condition to the exercise of an Option, the Board may require the person exercising such Option to execute an agreement with, and/or may require the person exercising such Option to make any representation and/or warranty to, the Company as may be, in the judgment of counsel to the Company, required under applicable law or regulation, including but not limited to a representation and warranty that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation and warranty is appropriate under any of the aforementioned relevant provisions of law. Section 22. Reservation of Shares. --------------------- The Company, during the term of this Plan, shall at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. The Company, during the term of this Plan, shall use its best efforts to seek to obtain from appropriate regulatory agencies any requisite authorization in order to issue and sell such number of Shares as shall be sufficient to satisfy the requirements of the Plan. The inability of the Company to obtain from any such regulatory agency having jurisdiction the requisite authorization(s) deemed by the Company's counsel to be necessary for the lawful issuance and sale of any Shares hereunder, or the inability of the Company to confirm to its satisfaction that any issuance and sale of any Shares hereunder will meet applicable legal requirements, shall relieve the Company of any liability in respect to the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained. Section 23. Stock Option and Stock Purchase Agreements. ------------------------------------------ -23-

Options shall be evidenced by an Option Agreement in such form or forms as the Board shall approve from time to time. Upon the exercise of an Option, the Optionee shall sign and deliver to the Company a Stock Purchase Agreement in such form or forms as the Board shall approve from time to time. Section 24. Taxes, Fees, Expenses and Withholding of Taxes. ---------------------------------------------- (1) The Company shall pay all original issue and transfer taxes (but not income taxes, if any) with respect to the Award of Options and/or the issue and transfer of Shares pursuant to the exercise thereof, and all other fees and expenses necessarily incurred by the Company in connection therewith, and will from time to time use its best efforts to comply with all laws and regulations which, in the opinion of counsel for the Company, shall be applicable thereto. (b) The Award of Options hereunder and the issuance of Shares pursuant to the exercise thereof is conditioned upon the Company's reservation of the right to withhold in accordance with any applicable law, from any compensation or other amounts payable to the Optionee, any taxes required to be withheld under federal, state or local law as a result of the Award or exercise of such Option or the sale of the Shares issued upon exercise thereof. To the extent that compensation or other amounts, if any, payable to the Optionee is insufficient to pay any taxes required to be so withheld, the Company may, in its sole discretion, require the Optionee (or such other person entitled herein to exercise the Option), as a condition of the exercise of an Option, to pay in cash to the Company an amount sufficient to cover such tax liability or otherwise to make adequate provision for the Company's satisfaction of its withholding obligations under federal, state and local law. -24-

Any such notice shall be deemed duly given when enclosed in a properly sealed envelope or wrapper addressed as aforesaid, registered or certified, and deposited, postage and registry or certification fee prepaid, in a post office or branch post office regularly maintained by the United States Postal Service. It shall be the obligation of each Optionee and each permitted transferee holding Shares purchased upon exercise of an Option to provide the Secretary of the Company, by letter mailed as provided herein, with written notice of his or her direct mailing address. Section 26. No Enlargement of Employee Rights. --------------------------------- This Plan is purely voluntary on the part of the Company, and the continuance of the Plan shall not be deemed to constitute a contract between the Company and any Employee, or to be consideration for or a condition of the employment or service of any Employee. Nothing contained in this Plan shall be deemed to give any Employee the right to be retained in the employ or service of the Company, its Parent, any Subsidiary or a successor corporation, or to interfere with the right of the Company or any such corporation to discharge or retire any Employee thereof at any time. No Employee shall have any right to or interest in Options authorized hereunder prior to the Award thereof to such Employee, and upon such Award he shall have only such rights and interests as are expressly provided herein, subject, however, to all applicable provisions of the Company's Certificate of Incorporation, as the same may be amended from time to time. Section 27. Information to Optionees. ------------------------ The Company, upon request, shall provide without charge to each Optionee copies of such annual and periodic reports as are provided by the Company to its stockholders generally.

Section 29. Invalid Provisions. ------------------ In the event that any provision of this Plan is found to be invalid or otherwise unenforceable under any applicable law, such invalidity or unenforceability shall not be construed as rendering any other provisions contained herein as invalid or unenforceable, and all such other provisions shall be given full force and effect to the same extent as though the invalid or unenforceable provision was not contained herein. Section 30. Applicable Law. -------------- This Plan shall be governed by and construed in accordance with the laws of the State of Delaware. Section 31.

All Awards will be subject to the following provisions: (a) Alternative Awards. If any Awards are designated in their Award Agreements as alternative to each other, the exercise of all or part of one Award automatically will cause an immediate equal (or pro rata) corresponding termination of the other alternative Award or Awards. 7

(b) Rights as Shareholders. No Participant will have any rights of a shareholder with respect to Shares subject to an Award until such Shares are issued in the name of the Participant. (c) Employment Rights. Neither the adoption of the Plan nor the granting of any Award will confer on any person the right to continued employment with Corporation or any Subsidiary or the right to remain as a director of Corporation or a member of any Advisory Committee, as the case may be, nor will it interfere in any way with the right of Corporation or a Subsidiary to terminate such person's employment or to remove such person as an Advisor or as a director at any time for any reason or for no reason, with or without cause. (d) Termination Of Employment. The terms and conditions under which an Award may be exercised or will continue to Vest, if at all, after a Participant's termination of employment or service as an Advisor or as a Non-Employee Director will be determined by the Committee and specified in the applicable Award Agreement. (e) Change in Control. The Committee, in its discretion, may provide in any Award Agreement that in the event of a change in control of Corporation (as the Committee may define such term in the Award Agreement), as of the date of such change in control: (i) All, or a specified portion of, Awards requiring exercise will become fully and immediately exercisable, notwithstanding any other limitations on exercise; (ii) All, or a specified portion of, Awards subject to Restrictions will become fully Vested; and (iii) All, or a specified portion of, Awards subject to Performance Goals will be deemed to have been fully earned. The Committee, in its discretion, may include change in control provisions in some Award Agreements and not in others, may include different change in control provisions in different Award Agreements, and may include change in control provisions for some Awards or some Participants and not for others. (f) Service Periods. At the time of granting Awards, the Committee may specify, by resolution or in the Award Agreement, the period or periods of service performed or to be performed by the Participant in connection with the grant of the Award. 6.6 Tax Withholding. (a) General. Corporation will have the right to deduct from any settlement, including the delivery or Vesting of Shares, made under the Plan any federal, state, or local taxes of any kind required by law to be withheld with 8

respect to such payments or to take such other action as may be necessary in the opinion of Corporation to satisfy all obligations for the payment of such taxes. The recipient of any payment or distribution under the Plan will make arrangements satisfactory to Corporation for the satisfaction of any such withholding tax obligations. Corporation will not be required to make any such payment or distribution under the Plan until such obligations are satisfied. (b) Stock Withholding. The Committee, in its sole discretion, may permit a Participant to satisfy all or a part of the withholding tax obligations incident to the settlement of an Award involving payment or delivery of Shares to the Participant by having Corporation withhold a portion of the Shares that would otherwise be issuable to the Participant. Such Shares will be valued based on their Fair Market Value on the date the tax withholding is required to be made. Any stock withholding with respect to a Reporting Person will be subject to such limitations as the Committee may impose to comply with the requirements of the Exchange Act. 6.7 Annulment of Awards. Any Award Agreement may provide that the grant of an Award payable in cash is provisional until cash is paid in settlement thereof or that grant of an Award payable in Shares is provisional until the Participant becomes entitled to the certificate in settlement thereof. In the event the employment (or service as an Advisor or membership on the Board) of a Participant is terminated for cause (as defined below), any Award that is provisional will be annulled as of the date of such termination for cause. For the purpose of this Section 6.7, the term "for cause" has the meaning set forth in the Participant's employment agreement, if any, or otherwise means any discharge (or removal) for material or flagrant violation of the policies and procedures of Corporation or for other job performance or conduct which is materially detrimental to the best interests of Corporation, as determined by the Committee. 6.8 Engaging in Competition With Corporation. Any Award Agreement may provide that, if a Participant terminates employment with Corporation or a Subsidiary for any reason whatsoever, and within 18 months after the date thereof accepts employment with any competitor of (or otherwise engages in competition with) Corporation, the Committee, in its sole discretion, may require such Participant to return to Corporation the economic value of any Award that is realized or obtained (measured at the date of exercise, Vesting, or payment) by such Participant at any time during the period beginning on the date that is six months prior to the date of such Participant's termination of employment with Corporation. ARTICLE 7 OPTIONS 7.1 Types of Options. Options granted under the Plan may be in the form of Incentive Stock Options or Nonqualified Options (including Deferred Compensation Options). The grant of each Option and the Award Agreement governing each Option will identify the Option as an ISO or an NQO. In the event the Code is amended to provide for tax-favored forms of stock options other than or in addition to Incentive Stock Options, the Committee may grant Options under the Plan meeting the requirements of such forms of options. 9

7.2 General. Options will be subject to the terms and conditions set forth in Article 6 and this Article 7 and may contain such additional terms and conditions, not inconsistent with the express provisions of the Plan, as the Committee (or the Board with respect to Awards to Non-Employee Directors) deems desirable. 7.3 Option Price. Each Award Agreement for Options will state the option exercise price per Share of Common Stock purchasable under the Option, which will not be less than: (a) $1 per share in the case of a Deferred Compensation Option; (b) 75 percent of the Fair Market Value of a Share on the date of grant for all other Nonqualified Options; or (c) 100 percent of the Fair Market Value of a Share on the date of grant for all Incentive Stock Options. 7.4 Option Term. The Award Agreement for each Option will specify the term of each Option, which may be unlimited or may have a specified period during which the Option may be exercised, as determined by the Committee. 7.5 Time of Exercise. The Award Agreement for each Option will specify, as determined by the Committee: (a) The time or times when the Option will become exercisable and whether the Option will become exercisable in full or in graduated amounts over a period specified in the Award Agreement; (b) Such other terms, conditions, and restrictions as to when the Option may be exercised as determined by the Committee; and (c) The extent, if any, to which the Option will remain exercisable after the Participant ceases to be an employee, Advisor, or director of Corporation or a Subsidiary. An Award Agreement for an Option may, in the discretion of the Committee, provide whether, and to what extent, the Option will become immediately and fully exercisable (i) in the event of the death, Disability, or Retirement of the Participant, or (ii) upon the occurrence of a change in control of Corporation. 7.6 Method of Exercise. The Award Agreement for each Option will specify the method or methods of payment acceptable upon exercise of an Option. An Award Agreement may provide that the option price is payable in full in cash or, at the discretion of the Committee: (a) In installments on such terms and over such period as the Committee determines; (b) In previously acquired Shares (including Restricted Shares); 10

(c) By surrendering outstanding Awards under the Plan denominated in Shares or in Share-equivalent units; (d) By delivery (in a form approved by the Committee) of an irrevocable direction to a securities broker acceptable to the Committee: (i) To sell Shares subject to the Option and to deliver all or a part of the sales proceeds to Corporation in payment of all or a part of the option price and withholding taxes due; or (ii) To pledge Shares subject to the Option to the broker as security for a loan and to deliver all or a part of the loan proceeds to Corporation in payment of all or a part of the option price and withholding taxes due; or (e) In any combination of the foregoing or in any other form approved by the Committee. If Restricted Shares are surrendered in full or partial payment of an Option price, a corresponding number of the Shares issued upon exercise of the Option will be Restricted Shares subject to the same Restrictions as the surrendered Restricted Shares. 7.7 Special Rules for Incentive Stock Options. In the case of an Option designated as an Incentive Stock Option, the terms of the Option and the Award Agreement must be in conformance with the statutory and regulatory requirements specified in Section 422 of the Code, as in effect on the date such ISO is granted. ISOs may be granted only to employees of Corporation or a Subsidiary. ISOs may not be granted under the Plan after February 15, 2010, unless the ten-year limitation of Section 422(b)(2) of the Code is removed or extended. 7.8 Restricted Shares. In the discretion of the Committee, the Shares issuable upon exercise of an Option may be Restricted Shares if so provided in the Award Agreement. 7.9 Deferred Compensation Options. The Committee may, in its discretion, grant Deferred Compensation Options with an option price less than Fair Market Value to provide a means for deferral of compensation to future dates. The option price will be determined by the Committee subject to Section 7.3(a) of the Plan. The number of Shares subject to a Deferred Compensation Option will be determined by the Committee, in its discretion, by dividing the amount of compensation to be deferred by the difference between the Fair Market Value of a Share on the date of grant and the option price of the Deferred Compensation Option. Amounts of compensation deferred with Deferred Compensation Options may include amounts earned under Awards granted under the Plan or under any other compensation program or arrangement of Corporation as permitted by the Committee. The Committee may grant Deferred Compensation Options only if it reasonably determines that the recipient of such an Option is not likely to be deemed to be in constructive receipt for income tax purposes of the income being deferred. 7.10 Reload Options. The Committee, in its discretion, may provide in an Award Agreement for an Option that in the event all or a portion of the Option is exercised by the 11

Participant using previously acquired Shares, the Participant will automatically be granted a replacement Option (with an option price equal to the Fair Market Value of a Share on the date of such exercise) for a number of Shares equal to (or equal to a portion of) the number of shares surrendered upon exercise of the Option. Such reload Option features may be subject to such terms and conditions as the Committee shall determine, including without limitation, a condition that the Participant retain the Shares issued upon exercise of the Option for a specified period of time. 7.11 Limitation on Number of Shares Subject to Options. In no event may Options for more than 500,000 Shares be granted to any individual under the Plan during any fiscal year period. ARTICLE 8 STOCK APPRECIATION RIGHTS 8.1 General. Stock Appreciation Rights will be subject to the terms and conditions set forth in Article 6 and this Article 8 and may contain such additional terms and conditions, not inconsistent with the express terms of the Plan, as the Committee (or the Board with respect to Awards to Non-Employee Directors) deems desirable. 8.2 Nature of Stock Appreciation Right. A Stock Appreciation Right is an Award entitling a Participant to receive an amount equal to the excess (or if the Committee determines at the time of grant, a portion of the excess) of the Fair Market Value of a Share of Common Stock on the date of exercise of the SAR over the base price, as described below, on the date of grant of the SAR, multiplied by the number of Shares with respect to which the SAR has been exercised. The base price will be designated by the Committee in the Award Agreement for the SAR and may be the Fair Market Value of a Share on the grant date of the SAR or such other higher or lower price as the Committee determines. 8.3 Exercise. A Stock Appreciation Right may be exercised by a Participant in accordance with procedures established by the Committee. The Committee may also provide that an SAR will be automatically exercised on one or more specified dates or upon the satisfaction of one or more specified conditions. In the case of SARs granted to Reporting Persons, exercise of the SAR will be limited by the Committee to the extent required to comply with the applicable requirements of Rule 16b-3 under the Exchange Act. 8.4 Form of Payment. Payment upon exercise of a Stock Appreciation Right may be made in cash, in installments, in Shares, by issuance of a Deferred Compensation Option, or in any combination of the foregoing, or in any other form as the Committee determines. 8.5 Limitation on Number of Shares Subject to SARs. In no event may SARs for more than 500,000 Shares be granted to any individual under the Plan during any fiscal year period. 12

ARTICLE 9 RESTRICTED AWARDS 9.1 Types of Restricted Awards. Restricted Awards granted under the Plan may be in the form of either Restricted Shares or Restricted Units. (a) Restricted Shares. A Restricted Share is an Award of Shares transferred to a Participant subject to such terms and conditions as the Committee deems appropriate, including, without limitation, restrictions on the sale, assignment, transfer, or other disposition of such Restricted Shares and may include a requirement that the Participant forfeit such Restricted Shares back to Corporation upon termination of Participant's employment (or service as an Advisor or Non-Employee Director) for specified reasons within a specified period of time or upon other conditions, as set forth in the Award Agreement for such Restricted Shares. Each Participant receiving a Restricted Share will be issued a stock certificate in respect of such Shares, registered in the name of such Participant, and will be required to execute a stock power in blank with respect to the Shares evidenced by such certificate. The certificate evidencing such Restricted Shares and the stock power will be held in custody by Corporation until the Restrictions thereon will have lapsed. (b) Restricted Units. A Restricted Unit is an Award of units (with each unit having a value equivalent to one Share) granted to a Participant subject to such terms and conditions as the Committee deems appropriate, and may include a requirement that the Participant forfeit such Restricted Units upon termination of Participant's employment (or service as an Advisor or Non-Employee Director) for specified reasons within a specified period of time or upon other conditions, as set forth in the Award Agreement for such Restricted Units. 9.2 General. Restricted Awards will be subject to the terms and conditions of Article 6 and this Article 9 and may contain such additional terms and conditions, not inconsistent with the express provisions of the Plan, as the Committee (or the Board with respect to Awards to Non-Employee Directors) deems desirable. 9.3 Restriction Period. Restricted Awards will provide that such Awards, and the Shares subject to such Awards, may not be transferred, and may provide that, in order for a Participant to Vest in such Awards, the Participant must remain in the employment (or remain as an Advisor or Non-Employee Director) of Corporation or its Subsidiaries, subject to relief for reasons specified in the Award Agreement, for a period commencing on the date of the Award and ending on such later date or dates as the Committee designates at the time of the Award (the "Restriction Period"). During the Restriction Period, a Participant may not sell, assign, transfer, pledge, encumber, or otherwise dispose of Shares received under or governed by a Restricted Award grant. The Committee, in its sole discretion, may provide for the lapse of restrictions in installments during the Restriction Period. Upon expiration of the applicable Restriction Period (or lapse of Restrictions during the Restriction Period where the Restrictions lapse in installments) the Participant shall be entitled to settlement of the Restricted Award or portion 13

thereof, as the case may be. Although Restricted Awards will usually Vest based on continued employment (or service as an Advisor or Non-Employee Director) and Performance Awards under Article 10 shall usually Vest based on attainment of Performance Goals, the Committee, in its discretion, may condition Vesting of Restricted Awards on attainment of Performance Goals as well as continued employment (or service as an Advisor or Non-Employee Director). In such case, the Restriction Period for such a Restricted Award will include the period prior to satisfaction of the Performance Goals. 9.4 Forfeiture. If a Participant ceases to be an employee, Advisor of Corporation or a Subsidiary or Non-Employee Director during the Restriction Period for any reason other than reasons which may be specified in an Award Agreement (such as death, Disability, or Retirement), the Award Agreement may require that all non-Vested Restricted Awards previously granted to the Participant be forfeited and returned to Corporation. 9.5 Settlement of Restricted Awards. (a) Restricted Shares. Upon Vesting of a Restricted Share Award, the legend on such Shares will be removed and the Participant's stock power will be returned and the Shares will no longer be Restricted Shares. The Committee may also, in its discretion, permit a Participant to receive, in lieu of unrestricted Shares at the conclusion of the Restriction Period, payment in cash, installments, a Deferred Compensation Option equal to the Fair Market Value of the Restricted Shares as of the date the Restrictions lapse, or in any other manner or combination of such methods as the Committee, in its sole discretion, determines. (b) Restricted Units. Upon Vesting of a Restricted Unit Award, a Participant will be entitled to receive payment for Restricted Units in an amount equal to the aggregate Fair Market Value of the Shares covered by such Restricted Units at the expiration of the Applicable Restriction Period. Payment in settlement of a Restricted Unit will be made as soon as practicable following the conclusion of the applicable Restriction Period in cash, in installments, in Shares equal to the number of Restricted Units, by issuance of a Deferred Compensation Option, or in any other manner or combination of such methods as the Committee, in its sole discretion, determines. 9.6 Rights as a Shareholder. A Participant will have, with respect to unforfeited Shares received under a grant of Restricted Shares, all the rights of a shareholder of Corporation, including the right to vote the Shares, and the right to receive any cash dividends. Stock dividends issued with respect to Restricted Shares will be treated as additional Shares covered by the grant of Restricted Shares and will be subject to the same Restrictions. ARTICLE 10 PERFORMANCE AWARDS 10.1 General. Performance Awards will be subject to the terms and conditions set forth in Article 6 and this Article 10 and may contain such other terms and conditions not 14

inconsistent with the express provisions of the Plan, as the Committee (or the Board with respect to Awards to Non-Employee Directors) deems desirable. 10.2 Nature of Performance Awards. A Performance Award is an Award of units (with each unit having a value equivalent to one Share) granted to a Participant subject to such terms and conditions as the Committee deems appropriate, including, without limitation, the requirement that the Participant forfeit such Performance Award or a portion thereof in the event specified performance criteria are not met within a designated period of time. 10.3 Performance Cycles. For each Performance Award, the Committee will designate a performance period (the "Performance Cycle") with a duration to be determined by the Committee in its discretion within which specified Performance Goals are to be attained. There may be several Performance Cycles in existence at any one time and the duration of Performance Cycles may differ from each other. 10.4 Performance Goals. The Committee will establish Performance Goals for each Performance Cycle on the basis of such criteria and to accomplish such objectives as the Committee may from time to time select. Performance Goals may be based on performance criteria for Corporation, a Subsidiary, or an operating group, or based on a Participant's individual performance. Performance Goals may include objective and subjective criteria. During any Performance Cycle, the Committee may adjust the Performance Goals for such Performance Cycle as it deems equitable in recognition of unusual or nonrecurring events affecting Corporation, changes in applicable tax laws or accounting principles, or such other factors as the Committee may determine. 10.5 Determination of Awards. As soon as practicable after the end of a Performance Cycle, the Committee will determine the extent to which Performance Awards have been earned on the basis of performance in relation to the established Performance Goals. 10.6 Timing and Form of Payment. Settlement of earned Performance Awards will be made to the Participant as soon as practicable after the expiration of the Performance Cycle and the Committee's determination under Section 10.5, in the form of cash, installments, Shares, Deferred Compensation Options, or any combination of the foregoing or in any other form as the Committee determines. 10.7 Performance Goals for Executive Officers. The performance goals for Performance Awards granted to executive officers of Corporation may relate to corporate performance, business unit performance, or a combination of both. (a) Corporate performance goals will be based on financial performance goals related to the performance of Corporation as a whole and may include one or more measures related to earnings, profitability, efficiency, or return to stockholders such as earnings per share, operating profit, stock price, costs of production, or other measures. (b) Business unit performance goals will be based on a combination of financial goals and strategic goals related to the performance of an identified business unit for which a Participant has responsibility. Strategic goals for a 15

business unit may include one or a combination of objective factors relating to success in implementing strategic plans or initiatives, introductory products, constructing facilities, or other identifiable objectives. Financial goals for a business unit may include the degree to which the business unit achieves one or more objective measures related to its revenues, earnings, profitability, efficiency, operating profit, costs of production, or other measures. (c) Any corporate or business unit goals may be expressed as absolute amounts or as ratios or percentages. Success may be measured against various standards, including budget targets, improvement over prior periods, and performance relative to other companies, business units, or industry groups. 10.8 Award Limitations. The maximum number of Shares issuable with respect to Performance Awards granted to any individual executive officer may not exceed 150,000 Shares for any calendar year. ARTICLE 11 OTHER STOCK-BASED AND COMBINATION AWARDS 11.1 Other Stock-Based Awards. The Committee (or the Board with respect to Awards to Non-Employee Directors) may grant other Awards under the Plan pursuant to which Shares are or may in the future be acquired, or Awards denominated in or measured by Share equivalent units, including Awards valued using measures other than the market value of Shares. Such Other Stock-Based Awards may be granted either alone, in addition to, or in tandem with, any other type of Award granted under the Plan. 11.2 Combination Awards. The Committee may also grant Awards under the Plan in tandem or combination with other Awards or in exchange of Awards, or in tandem or combination with, or as alternatives to, grants or rights under any other employee plan of Corporation, including the plan of any acquired entity. No action authorized by this section may reduce the amount of any existing benefits or change the terms and conditions thereof without the Participant's consent. ARTICLE 12 DEFERRAL ELECTIONS The Committee may permit a Participant to elect to defer receipt of the payment of cash or the delivery of Shares that would otherwise be due to such Participant by virtue of the exercise, earn-out, or Vesting of an Award made under the Plan. If any such election is permitted, the Committee will establish rules and procedures for such payment deferrals, including, but not limited to: (a) payment or crediting of reasonable interest on such deferred amounts credited in cash, (b) the payment or crediting of dividend equivalents in respect of deferrals credited in Share equivalent units, or (c) granting of Deferred Compensation Options. 16

ARTICLE 13 DIVIDEND EQUIVALENTS Any Awards may, at the discretion of the Committee, earn dividend equivalents. In respect of any such Award that is outstanding on a dividend record date for Common Stock, the Participant may be credited with an amount equal to the amount of cash or stock dividends that would have been paid on the Shares covered by such Award, had such covered Shares been issued and outstanding on such dividend record date. The Committee will establish such rules and procedures governing the crediting of dividend equivalents, including the timing, form of payment, and payment contingencies of such dividend equivalents, as it deems appropriate or necessary. ARTICLE 14 ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, ETC. 14.1 Plan Does Not Restrict Corporation. The existence of the Plan and the Awards granted hereunder will not affect or restrict in any way the right or power of the Board or the shareholders of Corporation to make or authorize any adjustment, recapitalization, reorganization, or other change in Corporation's capital structure or its business, any merger or consolidation of the Corporation, any issue of bonds, debentures, preferred or prior preference stocks ahead of or affecting Corporation's capital stock or the rights thereof, the dissolution or liquidation of Corporation or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding. 14.2 Adjustments by the Committee. In the event of any change in capitalization affecting the Common Stock of Corporation, such as a stock dividend, stock split, recapitalization, merger, consolidation, split-up, combination or exchange of shares or other form of reorganization, or any other change affecting the Common Stock, such proportionate adjustments, if any, as the Committee, in its sole discretion, may deem appropriate to reflect such change, will be made with respect to the aggregate number of Shares for which Awards in respect thereof may be granted under the Plan, the maximum number of Shares which may be sold or awarded to any Participant, the number of Shares covered by each outstanding Award, and the price per Share in respect of outstanding Awards. The Committee may also make such adjustments in the number of Shares covered by, and price or other value of any outstanding Awards in the event of a spin-off or other distribution (other than normal cash dividends), of Corporation assets to shareholders. ARTICLE 15 AMENDMENT AND TERMINATION The Board may amend, suspend, or terminate the Plan or any portion of the Plan at any time, provided no amendment may be made without shareholder approval if such approval is required by applicable law or the applicable requirements of a stock exchange or over-the-counter stock trading system. 17

ARTICLE 16 MISCELLANEOUS 16.1 Unfunded Plan. The Plan will be unfunded and Corporation will not be required to segregate any assets that may at any time be represented by Awards under the Plan. Any liability of Corporation to any person with respect to any Award under the Plan will be based solely upon any contractual obligations that may be effected pursuant to the Plan. No such obligation of Corporation will be deemed to be secured by any pledge of, or other encumbrance on, any property of Corporation. 16.2 Payments to Trust. The Committee is authorized (but has no obligation) to cause to be established a trust agreement or several trust agreements whereunder the Committee may make payments of amounts due or to become due to Participants in the Plan. 16.3 Other Corporation Benefit and Compensation Programs. Payments and other benefits received by a Participant under an Award made pursuant to the Plan will not be deemed a part of a Participant's regular, recurring compensation for purposes of the termination indemnity or severance pay law of any state or country and shall not be included in, or have any effect on, the determination of benefits under any other employee benefit plan or similar arrangement provided by Corporation or a Subsidiary unless expressly so provided by such other plan or arrangements, or except where the Committee expressly determines that an Award or portion of an Award should be included to accurately reflect competitive compensation practices or to recognize that an Award has been made in lieu of a portion of cash compensation. Awards under the Plan may be made in combination with or in tandem with, or as alternatives to, grants, awards, or payments under any other Corporation or Subsidiary plans, arrangements, or programs. The Plan notwithstanding, Corporation or any Subsidiary may adopt such other compensation programs and additional compensation arrangements as it deems necessary to attract, retain, and reward employees and directors for their service with Corporation and its Subsidiaries. 16.4 Securities Law Restrictions. No Shares may be issued under the Plan unless counsel for Corporation is satisfied that such issuance will be in compliance with applicable federal and state securities laws. Certificates for Shares delivered under the Plan may be subject to such stop-transfer orders and other restrictions as the Committee may deem advisable under the rules, regulations, and other requirements of the Securities and Exchange Commission, any stock exchange upon which the Common Stock is then listed, and any applicable federal or state securities law. The Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. 16.5 Governing Law. Except with respect to references to the Code or federal securities laws, the Plan and all actions taken thereunder shall be governed by and construed in accordance with the laws of the state of Delaware. 18

ARTICLE 17 SHAREHOLDER APPROVAL The Plan is expressly subject to the approval of the Plan by the shareholders at the 2000 annual meeting of Epitope Inc.'s shareholders. 19

                           ORASURE TECHNOLOGIES, INC.
                            MANAGEMENT INCENTIVE PLAN



ARTICLE I
                              OBJECTIVE OF THE PLAN

The purpose of this  Management  Incentive  Plan  ("Plan" or "MIP") is to reward
executives of ORASURE TECHNOLOGIES,  INC. (the "Company") for creating value for
the Company by maximizing financial performance against stated objectives.


ARTICLE II
                               PLAN ADMINISTRATION

The Plan is administered by the Board's Compensation Committee (the "Committee")
and all  matters  shall be  decided on by  general  consensus  as defined in the
Committee's Charter.

The Plan is an annual  program and is effective  January 1, 2001 and will remain
in effect until the Compensation Committee determines otherwise. A new Plan year
will commence on the first business day of the fiscal year.

ARTICLE III
                                  PARTICIPANTS

Generally  all active  managerial  employees  and above,  currently  meeting job
requirements,  shall be eligible to  participate in the Plan.  Participation  is
limited to those employees selected by the Compensation Committee to participate
in the Plan during each fiscal year.


ARTICLE IV
                             PERFORMANCE OBJECTIVES

Prior to or at the  beginning of each fiscal year,  the  Compensation  Committee
shall establish:

      (i)  performance  objectives  for  the  Company,  any  Subsidiary,  or any
business segment or unit of the Company, based upon such criteria as may be from
time to time considered by the Compensation Committee, and

      (ii) the award formula or matrix by which all bonuses under this Plan will
be calculated and determined for Compensation Committee review and approval.

The  maximum  bonus that may be awarded  under this Plan to any one  participant
shall be 200% of a participant's bonus target.


ARTICLE V
                               AWARD CALCULATIONS

Each Plan  participant  will be assigned a target  award that will be awarded if
the Company achieves its targeted performance goals. These target awards will be
leveraged up when


Company performance exceeds expectations, or down if Company performance falls below expectations. Following are the target awards by position. CEO - 50% COO/CSO - 40% Senior Vice Presidents - 30% Vice Presidents - 20% Directors - 15% Managers - 5% A bonus pool will be funded based on the Company's performance against pre-established SALES goals and EARNINGS PER SHARE (EPS) goals (see Table A). For example, per the approved budget, in 2001 if Sales are $43 Million and the EPS is $0.10 per share, then 100% of the incentive pool will be funded. The pool is determined by aggregating targeted awards for all participants. Awards will be interpolated for performance results that fall between numbers on the Corporate Award Performance Matrix. TABLE A Corporate Award Performance Matrix ---------------------------------------------------------- EPS ---------------------------------------------------------- $.075 $.010 $.125 $.15 ---------------------------------------------------------- $51.6 125% 150% 175% 200% ---------------------------------------------------------- $47.3 100% 125% 150% 175% ---------------------------------------------------------- SALES $43.0 75% 100% 125% 150% ---------------------------------------------------------- $38.7 50% 75% 100% 125% ---------------------------------------------------------- After the Corporate Award pool is determined, managers will then have the opportunity to recommend adjustments to the CEO for each participant's Corporate Award for Individual performance. Awards for the CEO, COO, CSO, and CFO will be based 75% on reaching corporate revenue objectives and 25% on non-financial objectives/measures. Awards for all other officers will be based 50% on reaching corporate objectives and 50% based on non-financial objectives. All other individual performance will be based on a participant's performance rating under the Company's performance evaluation program. Awards may be adjusted up or down up to 50% based on Individual performance. However any adjustment must ultimately result in a zero sum. ARTICLE VI ADMINISTRATIVE MATTERS As soon as practicable after each Plan year, the Compensation Committee shall determine whether the Company, any Subsidiary, or any business segment or unit of the Company attained their pre-established performance objectives. Assuming such performance objectives are attained, the Compensation Committee shall determine, in its sole and exclusive discretion, whether any bonuses shall be awarded for such Plan year. Such bonuses shall be awarded as soon as practicable thereafter and the Plan participants who are entitled to receive such bonuses shall be promptly notified of the award thereof. In the event that a Plan participant transfers in to a position that is designated as eligible for Plan participation, then any earned bonus in the Plan year will be prorated as of the month in which the

transfer occurred. If a Plan participant transfers into a position that is designated not eligible for Plan participation, the employee will forfeit any participation in the plan. In the event of death, permanent disability, retirement or involuntary termination without cause, unpaid bonuses will be calculated on a pro-rated basis by taking the number of full months, including the month in which the terminating event occurred, and dividing those months by twelve. In the event of voluntary termination or involuntary termination for cause, the Plan participant will forfeit any unpaid bonus earned under this Plan. A Plan participant not employed by the Company or a Subsidiary on the last day of the Plan year will forfeit his or her earned but unpaid bonus unless otherwise determined by the Compensation Committee. ARTICLE VII NO ENTITLEMENT TO BONUS Plan participants are entitled to a distribution under this Plan only upon the approval of the award by the Compensation Committee and no Participant shall be entitled to a bonus under the Plan unless the bonus is based on the attainment of performance objectives defined under the Plan. ARTICLE VIII TERMINATION OF PLAN The Compensation Committee reserves the right to amend or terminate the Plan at any time within thirty days written notice to Plan participants. In the event of a Plan termination, Plan participants will continue to be eligible for bonus awards, if earned, for the current Plan year. Bonus awards will be calculated from the date of the Plan termination and payable as soon as practicable after the end of the Plan year. ARTICLE IX PARTICIPANT'S RIGHT OF ASSIGNABILITY Participant awards shall not be subject to assignment, pledge or other disposition, nor shall such amounts be subject to garnishment, attachment, transfer by operation of law, or any legal process. Nothing contained in this Plan shall confer upon employees any right to continued employment, nor interfere with the right of the Company to terminate a participant's employment from the Company. Participation in the Plan does not confer rights to participation in other Company programs, including annual or long-term incentive plans, non-qualified retirement or deferred compensation plans or other executive perquisite programs.
