Business. PART I We discover, develop, manufacture, market, sell, distribute and support veterinary products. Our core focus is on the canine and feline companion animal health markets where we strive to provide high value products for latent needs and advance the state of veterinary medicine. 1 Our business is comprised of two reportable segments, Core Companion Animal Health and Other Vaccines, Pharmaceuticals and Products. The Core Companion Animal Health segment (“CCA”) includes diagnostic and other instruments and supplies as well as single use diagnostic and other tests, vaccines and pharmaceuticals, primarily for canine and feline use. These products are sold directly by us as well as through independent third party distributors and other distribution relationships. The Other Vaccines, Pharmaceuticals and Products segment (“OVP”), previously reported as Diamond Animal Health, includes private label vaccine and pharmaceutical production, primarily for cattle but also for other animals including small mammals and fish. All OVP products are sold by third parties under third party labels. Our principal executive offices are located at 3760 Rocky Mountain Avenue, Loveland, Colorado 80538, our telephone number is (970) 493-7272 and our internet address is www.heska.com. We were incorporated in California in 1988, and we reincorporated in Delaware in 1997. Background We were incorporated as Paravax, Inc. in 1988 and conducted research on vaccines to prevent infections by parasites. In 1991, we moved our headquarters from California to northern Colorado in order to be located closer to the research facilities of the College of Veterinary Medicine and Biomedical Sciences of Colorado State University. In 1995, we changed our name to Heska Corporation. Between 1996 and 1998, we expanded our business, making several acquisitions and significantly increasing our sales and marketing activities. During 1999 and 2000, we restructured and refocused our business, making several divestitures. We continued to be a research and development-focused company, devoting substantial resources to the research and development of innovative products for the companion animal health market. We continued to pursue operating efficiencies and rationalize our business in 2001 and 2002. In late 2001, we modified our sales strategy to a distributor-focused model and entered into distribution agreements with over 20 third-party veterinary distributors. We eliminated several direct sales positions as a result. We also consolidated our European operations into one facility in the fourth quarter of 2001. In the first half of 2002, we eliminated several positions, primarily in research and development, to lower our expense base. In July 2002, we licensed to Intervet Inc. certain rights to patents, trademarks and know-how for our Flu AVERT I.N. equine influenza vaccine, the world’s first intranasal influenza vaccine for horses. This was the result of a strategic decision to focus our resources on the canine and feline veterinary markets. In the years since 2003, we have continued to focus our efforts on operating improvements, selling consumables into the installed base of instruments we have built and seeking new product opportunities with third parties. Core Companion Animal Health Segment We presently sell a variety of companion animal health products and services, among the most significant of which are the following: Veterinary Instruments We offer a line of veterinary diagnostic and other instruments which are described below. We also market and sell consumable supplies for these instruments. Our line of veterinary instruments includes the following: · Electrolytes and Blood Gases. The i-STAT Handheld Clinical Analyzer is a handheld, portable clinical analyzer that provides quick, easy analysis of blood gases and other key analytes, such as sodium, potassium and glucose, in whole blood. In January 2007, we introduced the i- STAT 1 Handheld Clinical Analyzer, with improvements over the original analyzer including expanded testing capabilities, upgraded storage capacity and ergonomic improvements. We are supplied 2 these instruments and affiliated cartridges and supplies under a contractual agreement with i-STAT Corporation (currently a unit of Abbott Laboratories which is to be sold to General Electric Company based on a January 17, 2007 announcement). · Blood Chemistry. The SPOTCHEM EZ Automated Dry Chemistry System is a compact benchtop system used to measure common blood chemistry components that are vital to veterinary medical diagnosis. It provides veterinarians with an easy-to-use, flexible and economical in- clinic chemistry system. We are supplied this instrument and affiliated test strips and supplies under a contractual agreement with Arkray Global Business, Inc. (“Arkray”). · Hematology. The HESKA CBC-DIFF Veterinary Hematology System is an easy-to-use blood analyzer that measures such key parameters as white blood cell count, red blood cell count, platelet count and hemoglobin levels in animals. We are supplied this instrument and affiliated reagents and supplies under a contractual agreement with Boule Medical AB (“Boule”). · IV Pumps. The VET/IV 2.2 infusion pump is a compact, affordable IV pump that allows veterinarians to easily provide regulated infusion of fluids, drugs or nutritional products for their patients. Point-of-Care Diagnostic and Other Tests Heartworm Diagnostic Products. Heartworm infections of dogs and cats are caused by the parasite Dirofilaria immitis. This parasitic worm is transmitted in larval form to dogs and cats through the bite of an infected mosquito. Larvae develop into adult worms that live in the pulmonary arteries and heart of the host, where they can cause serious cardiovascular, pulmonary, liver and kidney disease. Our canine and feline heartworm diagnostic tests use monoclonal antibodies or a recombinant heartworm antigen, respectively, to detect heartworm antigens or antibodies circulating in the blood of an infected animal. We currently market and sell heartworm diagnostic tests for both dogs and cats. SOLO STEP CH for dogs and SOLO STEP FH for cats are available in point-of-care, single use formats that can be used by veterinarians on site. We also offer SOLO STEP CH Batch Test Strips, a rapid and simple point-of-care antigen detection test for dogs that allows veterinarians in larger practices to run multiple samples at the same time. We obtain SOLO STEP CH, SOLO STEP FH and SOLO STEP Batch Test Strips under a contractual agreement with Quidel Corporation (“Quidel”). Early Renal Damage Detection Products. Renal damage is a leading cause of death in both dogs and cats. Several inflammatory, infectious or neoplastic diseases can damage an animal’s kidneys. It is estimated that 70% to 80% of kidney function is already destroyed before veterinarians can detect renal damage using traditional tests. Early detection is key to eliminate the causes and to mitigate the effects of kidney damage. Identification and treatment of the underlying cause of kidney damage can slow the progression of disease and add quality years to an animal’s life. Our E.R.D.-HEALTHSCREEN Canine Urine Test and our E.R.D.-HEALTHSCREEN Feline Urine Test are rapid in-clinic immunoassay tests designed to detect microalbuminuria, the most sensitive indicator of renal damage. Veterinary Diagnostic Laboratory Services and Products Allergy Diagnostic Services. Allergy is common in companion animals, and it has been estimated to affect approximately 10% to 15% of dogs. Clinical symptoms of allergy are variable, but are often manifested as persistent and serious skin disease in dogs and cats. Clinical management of allergic disease is 3 problematic, as there are a large number of allergens that may give rise to these conditions. Although skin testing is often regarded as the most accurate diagnostic procedure, such tests can be painful, subjective and inconvenient. The effectiveness of the immunotherapy that is prescribed to treat allergic disease is inherently limited by inaccuracies in the diagnostic process. We have veterinary diagnostic laboratories in Loveland, Colorado and Fribourg, Switzerland. Both diagnostic laboratories offer blood testing using our ALLERCEPT Definitive Allergen Panels, which provide the most accurate determination of the specific allergens to which an animal, such as a dog, cat or horse, is reacting. The panels use a highly specific recombinant version of the natural IgE receptor to test the serum of potentially allergic animals for IgE directed against a panel of known allergens. A typical test panel consists primarily of various pollen, grass, mold, insect and mite allergens. The test results serve as the basis for prescription ALLERCEPT Allergy Treatment Sets, discussed later in this document. In our Fribourg diagnostic laboratory, we also offer preliminary blood testing to screen for the presence of allergen-specific IgE using products based on our ALLERCEPT Definitive Allergen Panels. Animals testing positive for allergen-specific IgE are candidates for further evaluation using our ALLERCEPT Definitive Allergen Panels. Other Products and Services. Outside of the United States, we sell kits to conduct blood testing using our ALLERCEPT Definitive Allergen Panels to third-party veterinary diagnostic laboratories. We also sell products to screen for the presence of allergen-specific IgE to third party veterinary diagnostic laboratories outside of the United States — we sell kits to conduct preliminary blood testing using products based on our ALLERCEPT Definitive Allergen Panels as well as a similar test requiring less technical sophistication, our ALLERCEPT E-SCREEN Test. We sell ERD Reagent Packs used to detect microalbuminuria, the most sensitive indicator of renal damage, to Antech Diagnostics, the laboratory division of VCA Antech, Inc., for use in its veterinary diagnostic laboratories. Our Loveland veterinary diagnostic laboratory currently also offers testing using our canine and feline heartworm, renal damage, immune status and flea bite allergy assays as well as other diagnostic services including polymerase chain reaction, or PCR, based tests for certain infectious diseases. Our Loveland diagnostic laboratory is currently staffed by medical technologists experienced in animal disease and several additional technical staff. We intend to continue to use our Loveland veterinary diagnostic laboratory both as a stand-alone service center for our customers and as an adjunct to our product development efforts. Many of the assays which we intend to develop for in-clinic use are initially validated in the veterinary diagnostic laboratory and may be offered commercially in this format in the future. Vaccines and other Biologicals Allergy Treatment. Veterinarians who use our ALLERCEPT Definitive Allergen Panels often purchase ALLERCEPT Allergy Treatment Sets for those animals with positive test results. These prescription immunotherapy treatment sets are formulated specifically for each allergic animal and contain only the allergens to which the animal has significant levels of IgE antibodies. The prescription formulations are administered in a series of injections, with doses increasing over several months, to ameliorate the allergic condition of the animal. Immunotherapy is generally continued for an extended time. We offer canine, feline and equine immunotherapy treatment products. Feline Respiratory Disease. The use of injectable vaccines in cats has become controversial due to the frequency of injection site-associated side effects. The most serious of these side effects are injection site 4 sarcomas, tumors which, if untreated, are nearly always fatal. While there is one competitive non-injectable two-way vaccine, all other competitive products are injectable formulations. We sell the FELINE ULTRANASAL FVRCP Vaccine, a three-way modified live vaccine combination to prevent disease caused by the three most common respiratory viruses of cats: calicivirus, rhinotracheitis virus and panleukopenia virus. Our two-way modified live vaccine combination, FELINE ULTRANASAL FVRC, prevents disease caused by calicivirus and rhinotracheitis. These vaccines are administered without needle injection by dropping the liquid preparation into the nostrils of cats. Our vaccines avoid injection site side effects, and we believe they are very efficacious. Pharmaceuticals and Supplements Heartworm Prevention. We have an agreement with Schering-Plough Animal Health Corporation (“SPAH”), the worldwide animal health care business of Schering-Plough Corporation, granting SPAH the distribution and marketing rights in the United States for TRI-HEART Plus Chewable Tablets, our canine heartworm prevention product. TRI-HEART Plus Chewable Tablets (ivermectin/pyrantel) are indicated for use as a monthly preventive treatment of canine heartworm infection and for treatment and control of ascarid and hookworm infections. We manufacture TRI-HEART Plus Chewable Tablets at our Des Moines, Iowa production facility. Our TRI-HEART Plus Chewable Tablets also have been approved for sale in Japan and South Korea. Nutritional Supplements. We sell a novel fatty acid supplement, HESKA F.A. Granules. The source of the fatty acids in this product, flaxseed oil, leads to high omega-3:omega-6 ratios of fatty acids. Diets high in omega-3 fatty acids are believed to lead to lower levels of inflammatory mediators. The HESKA F.A. Granules include vitamins and are formulated in a palatable flavor base that makes the product convenient and easy to administer. Hypothyroid Treatment. We sell a chewable thyroid supplement, THYROMED Chewable Tablets, for treatment of hypothyroidism in dogs. Hypothyroidism is one of the most common endocrine disorders diagnosed in older dogs, treatment of which requires a daily hormone supplement for the lifetime of the animal. THYROMED Chewable Tablets contain the active ingredient Levothyroxine Sodium, which is a clinically proven replacement for the naturally occurring hormone secreted by the thyroid gland. The chewable formulation makes this daily supplement convenient and easy to administer. Other Vaccines, Pharmaceuticals and Products Segment We have developed our own line of bovine vaccines that are licensed by the United States Department of Agriculture (“USDA”). We have a long- term agreement with a distributor, Agri Laboratories, Ltd., (“AgriLabs”), for the marketing and sale of certain of these vaccines which are sold primarily under the TitaniumÒ and MasterGuardÒ brands — registered trademarks of AgriLabs. AgriLabs has rights to sell these bovine vaccines in the United States, Africa, China, Mexico and Taiwan to December 2013. Subject to minimum purchase requirements, AgriLabs’ rights in these regions will be exclusive at least to December 2009 and could remain exclusive up to December 2013 based on other contractual arrangements. We have the right to sell these bovine vaccines to any party of our choosing in other regions of the world. AgriLabs has non-exclusive rights to these vaccines in Canada to December 2009. We also manufacture other bovine products not covered under the agreement with AgriLabs. We manufacture biological and pharmaceutical products for a number of other animal health companies. We manufacture products for animals including small mammals and fish. Our offerings range from providing complete turnkey services which include research, licensing, production, labeling and 5 packaging of products to providing any one of these services as needed by our customers as well as validation support and distribution services. Marketing, Sales, Distribution and Customer Support We estimate that there are approximately 40,000 veterinarians in the United States whose practices are devoted principally to small animal medicine. Those veterinarians practice in approximately 20,000 clinics in the United States. In 2006, our products were sold to approximately 13,500 such clinics in the United States. Veterinarians may obtain our products directly from us or indirectly from others, such as independent third-party distributors. All our Core Companion Animal Health Products are ultimately sold to or through veterinarians. In many cases, veterinarians will markup their costs to the end user. The acceptance of our products by veterinarians is critical to our success. We currently market our Core Companion Animal Health products in the United States to veterinarians through a direct sales force, a telephone sales force, independent third-party distributors, as well as through trade shows and print advertising and other distribution relationships, such as SPAH in the case of our heartworm preventive. Our direct sales force currently consists of 26 territory managers and 3 regional managers responsible for sales in various parts of the United States. Our inside sales force consists of 23 persons. Our independent third-party distributors in the U.S. purchase and market our Core Companion Animal Health products utilizing their direct sales forces. We currently have agreements with 18 regional distributors with approximately 721 field representatives. We believe that one of our largest competitors, IDEXX Laboratories, Inc. (“IDEXX”), in effect prohibits its distributors from selling competitive products, including our diagnostic instruments and heartworm diagnostic tests. As a result, 11 of these 18 regional distributors with approximately 158 field representatives carry our full distribution product line. We believe the IDEXX restrictions limit our ability to engage national independent third party distributors to sell our full distribution line of products. We have a staff dedicated to customer and product support in our Core Companion Animal Health segment including veterinarians, technical support specialists and service technicians. Individuals from our research and development group may also be used as a resource in responding to certain product inquiries. Internationally, we market our Core Companion Animal Health products to veterinarians primarily through third-party veterinary diagnostic laboratories, independent third-party distributors and Novartis Agro K.K., Tokyo (“Novartis Japan”). These entities typically have distribution rights and provide customer support. Novartis Japan exclusively markets and distributes SOLO STEP CH and has exclusive marketing rights to our TRI-HEART Plus Chewable Tablets in Japan. All OVP products are marketed and sold by third parties under third party labels. AgriLabs currently has exclusive sales and marketing rights to certain of our bovine vaccines, which are sold primarily under the TitaniumÒ and MasterGuardÒ labels, in the United States and certain international regions. We grant third parties rights to certain of our existing products as well as to our intellectual property, with our compensation often taking the form of royalties and/or milestone payments. For example, we have an agreement with Nestlé Purina PetCare Company (“Purina”), a unit of Nestlé S.A., under which Purina pays royalties on certain pet food products it markets based on our patent-protected science. 6 Manufacturing The majority of our product revenue is from proprietary products manufactured by third parties. Third parties manufacture our veterinary instruments, including affiliated consumables and supplies, as well as other products including our heartworm point-of-care diagnostic tests, our allergy treatment products and our E.R.D.-HEALTHSCREEN Urine Tests. Our handheld analyzers and affiliated supplies are supplied under a contractual agreement with i-STAT Corporation (currently a unit of Abbott Laboratories which is to be sold to General Electric Company based on a January 17, 2007 announcement), our chemistry analyzers and affiliated supplies are supplied under a contractual agreement with Arkray, and our hematology analyzers and affiliated supplies are supplied under a contractual agreement with Boule. ALK-Abelló, Inc. manufactures our immunotherapy treatment products. Diagnostic Chemicals Limited manufactures our ERD Reagent Packs used to detect microalbuminuria in veterinary diagnostic laboratories and our E.R.D.- HEALTHSCREEN Urine Tests. Quidel and we, at our Des Moines facility, manufacture our heartworm point-of-care diagnostic tests. Our facility in Des Moines, Iowa is a USDA, Food and Drug Administration (“FDA”), and Drug Enforcement Agency (“DEA”) licensed biological and pharmaceutical manufacturing facility. This facility currently has the capacity to manufacture more than 50 million doses of vaccine each year. We expect that we will manufacture most or all of our biological and pharmaceutical products at this facility, as well as most or all of our recombinant proteins and other proprietary reagents for our diagnostic tests. We currently manufacture our canine heartworm prevention product, our FELINE ULTRANASAL Vaccines and all our OVP segment products at this facility. Our OVP segment’s customers purchase products in both bulk and finished format, and we perform all phases of manufacturing, including growth of the active bacterial and viral agents, sterile filling, lyophilization and packaging at this facility. We manufacture our various allergy diagnostic products at our Des Moines facility, our Loveland facility and our Fribourg facility. We believe the raw materials for products we manufacture are available from several sources. Product Development We are committed to providing innovative products to address latent health needs of companion animals. We may obtain such products from external sources, external collaboration or internal research and development. We are committed to identifying external product opportunities and creating business and technical collaborations that lead to high value veterinary products. We believe that our active participation in scientific networks and our reputation for investing in research enhances our ability to acquire external product opportunities. We have collaborated, and intend to continue to do so, with a number of companies and universities. Examples of such collaborations include: · Quidel for the development of SOLO STEP CH Cassettes, SOLO STEP CH Batch Test Strips and SOLO STEP FH Cassettes; · Diagnostic Chemicals, Ltd., for the development of the canine and feline E.R.D.-HEALTHSCREEN Urine Tests and ERD Reagent Packs to detect microalbuminuria; · Boule Medical AB for the development of veterinary applications for the HESKA CBC-DIFF Hematology System and associated reagents. Internal research and development is managed on a case-by-case basis. We employ individuals with microbiology, immunology, genetics, biochemistry, molecular biology, parasitology as well as veterinary expertise and will form multidisciplinary product-associated teams as appropriate. We incurred expenses of 7 $5.9 million, $3.7 million and $3.5 million in the years ended December 31, 2004, 2005 and 2006, respectively, in support of our research and development activities. Intellectual Property We believe that patents, trademarks, copyrights and other proprietary rights are important to our business. We also rely upon trade secrets, know- how, continuing technological innovations and licensing opportunities to develop and maintain our competitive position. The proprietary technologies of our OVP segment and Heska AG, our operating subsidiary in Switzerland, are primarily protected through trade secret protection of, for example, our manufacturing processes in these areas. We actively seek patent protection both in the United States and abroad. Our issued and pending patent portfolios primarily relate to allergy, flea control, heartworm control, infectious disease vaccines, diagnostic and detection tests, immunomodulators, instrumentation, nutrition, pain control and vaccine delivery technologies. As of December 31, 2006, we owned, co-owned or had rights to 157 issued U.S. patents and 50 pending U.S. patent applications expiring at various dates from June 2008 to August 2022. Applications corresponding to pending U.S. applications have been or will be filed in other countries. Our corresponding foreign patent portfolio as of December 31, 2006 included 58 issued patents and 57 pending applications in various foreign countries. We have entered into a number of out-licensing agreements to realize additional value in certain of our intellectual property assets in fields outside of our core focus. For example, in 1998 we obtained rights from ImmuLogic Pharmaceutical Corporation to an intellectual property portfolio including a number of major allergens and the genes that encode them for use in veterinary as well as human allergy applications. In order to realize additional value from that portfolio, we granted licenses and options for licenses to several companies for the use of those allergens in the fields of diagnosis and treatment of human allergy. In December 2006, we sold this intellectual property portfolio to Allergopharma Joachim Ganzer KG and obtained an exclusive license to veterinary rights for this intellectual property portfolio as part of the agreement. We also have obtained exclusive and non-exclusive licenses for numerous other patents held by academic institutions and biotechnology and pharmaceutical companies. Seasonality We expect the last six months of the year will outperform the first half of the year, both in terms of revenue and profitability. We expect to experience less seasonality than we have in the past due to factors including increased instrument consumable revenue, which does not tend to be seasonal, and changes in the timing of certain product promotions. Government Regulation Although the majority of our product revenue is from the sale of unregulated items, many of our products or products that we may develop are, or may be, subject to extensive regulation by governmental authorities in the United States, including the USDA and the FDA, and by similar agencies in other countries. These regulations govern, among other things, the development, testing, manufacturing, labeling, storage, pre-market approval, advertising, promotion, sale and distribution of our products. Satisfaction of these requirements can take several years to achieve and the time needed to satisfy them may vary substantially, based on the type, complexity and novelty of the product. Any product that we develop must receive all relevant regulatory approval or clearances, if required, before it may be marketed in a particular country. The following summarizes the U.S. government agencies that regulate animal health products: 8 · USDA. Vaccines and certain single use, point-of-care diagnostics are considered veterinary biologics and are therefore regulated by the Center for Veterinary Biologics, or CVB, of the USDA. Industry data indicate that it takes approximately four years and $1.0 million to license a conventional vaccine for animals from basic research through licensing. In contrast to vaccines, single use, point-of-care diagnostics can typically be licensed by the USDA in about two years, at considerably less cost. However, vaccines or diagnostics that use innovative materials, such as those resulting from recombinant DNA technology, usually require additional time to license. The USDA licensing process involves the submission of several data packages. These packages include information on how the product will be manufactured, information on the efficacy and safety of the product in laboratory and target animal studies and information on performance of the product in field conditions. · FDA. Pharmaceutical products, which generally include synthetic compounds, are approved and monitored by the Center for Veterinary Medicine of the FDA. Industry data indicate that developing a new drug for animals requires approximately 11 years from commencement of research to market introduction and costs approximately $5.5 million. Of this time, approximately three years is spent in animal studies and the regulatory review process. However, unlike human drugs, neither preclinical studies nor a sequential phase system of studies are required. Rather, for animal drugs, studies for safety and efficacy may be conducted immediately in the species for which the drug is intended. Thus, there is no required phased evaluation of drug performance, and the Center for Veterinary Medicine will review data at appropriate times in the drug development process. In addition, the time and cost for developing companion animal drugs may be significantly less than for drugs for livestock animals, as food safety issues relating to tissue residue levels are not applicable. · EPA. Products that are applied topically to animals or to premises to control external parasites are regulated by the Environmental Protection Agency, or EPA. After we have received regulatory licensing or approval for our products, numerous regulatory requirements typically apply. Among the conditions for certain regulatory approvals is the requirement that our manufacturing facilities or those of our third-party manufacturers conform to current Good Manufacturing Practices or other manufacturing regulations, which include requirements relating to quality control and quality assurance as well as maintenance of records and documentation. The USDA, FDA and foreign regulatory authorities strictly enforce manufacturing regulatory requirements through periodic inspections. A number of our animal health products are not regulated. For example, certain products such as our E.R.D.-HEALTHSCREEN Urine Tests and our ALLERCEPT panels, as well as other reference lab tests, are not regulated by either the USDA or FDA. Similarly, none of our veterinary instruments requires regulatory approval to be marketed and sold in the United States. Additionally, various botanically derived products, various nutritional products and supportive care products are exempt from significant regulation as long as they do not bear a therapeutic claim that represents the product as a drug. We have pursued regulatory approval outside the United States based on market demographics of foreign countries. For marketing outside the United States, we are subject to foreign regulatory requirements governing regulatory licensing and approval for many of our products. Licensing and approval by comparable regulatory authorities of foreign countries must be obtained before we can market products in those countries. Product licensing approval processes and requirements vary from country to country and the time required for such approvals may differ substantially from that required in the United States. We cannot be certain that approval of any of our products in one country will result in approvals in any other country. To date, we or our distributors have sought regulatory approval for certain of our products in Canada, which is governed by the Canadian Food Inspection Agency, or CFIA; in Japan, which is governed by the Japanese 9 Ministry of Agriculture, Forestry and Fisheries, or MAFF; and in certain European and other Asian countries requiring such approval. Core Companion Animal Health products previously discussed which have received regulatory approval in the United States and/or elsewhere are summarized below.

Our competitors include independent animal health companies and major pharmaceutical companies that have animal health divisions. We also compete with independent, third party distributors, including distributors who sell products under their own private labels. In the point-of-care diagnostic testing market, our major competitors include IDEXX, Abaxis, Inc. and Synbiotics Corporation. The products manufactured by our OVP segment for sale by third parties compete with similar products offered by a number of other companies, some of which have substantially greater financial, technical, research and other resources than us and may have more established marketing, sales, distribution and service organizations than our OVP segment’s customers. Companies with a significant presence in the animal health market such as Bayer AG, Intervet International bv (a unit of Akzo Nobel), Merial Limited, Novartis AG, Pfizer Inc., Schering-Plough Corporation, Virbac S.A. and Wyeth may be marketing or developing products that compete with our products or would compete with them if successfully developed. These and other competitors and potential competitors may have substantially greater financial, technical, research and other resources and larger, more established marketing, sales, distribution and service organizations than we do. Our competitors may offer broader product lines and have greater name recognition than we do. We believe that one of our largest competitors, IDEXX, in effect prohibits its distributors from selling competitive products, including our diagnostic instruments and heartworm diagnostic tests. Environmental Regulation In connection with our product development activities and manufacturing of our biological, pharmaceutical and diagnostic and detection products, we are subject to federal, state and local laws, rules, 10 regulations and policies governing the use, generation, manufacture, storage, handling and disposal of certain materials, biological specimens and wastes. Although we believe that we have complied with these laws, regulations and policies in all material respects and have not been required to take any significant action to correct any noncompliance, we may be required to incur significant costs to comply with environmental and health and safety regulations in the future. Although we believe that our safety procedures for handling and disposing of such materials comply with the standards prescribed by state and federal regulations, the risk of accidental contamination or injury from these materials cannot be eliminated. In the event of such an accident, we could be held liable for any damages that result and any such liability could exceed our resources. Employees As of December 31, 2006, we and our subsidiaries employed 299 people, of whom 123 were in sales, marketing, distribution and customer support, 99 were in production and veterinary diagnostic laboratories, 54 were in management and administration and 23 were in research, development and regulatory affairs. We believe that our ability to attract and retain skilled personnel is critical to our success. None of our employees is covered by a collective bargaining agreement, and we believe our employee relations are good.

Risk Factors Our future operating results may vary substantially from period to period due to a number of factors, many of which are beyond our control. The following discussion highlights these factors and the possible impact of these factors on future results of operations. If any of the following factors actually occur, our business, financial condition or results of operations could be harmed. In that case, the price of our common stock could decline and you could experience losses on your investment. We may be unable to successfully market, sell and distribute our products. We may not successfully develop and maintain marketing, sales or distribution capabilities, and we may not be able to make arrangements with third parties to perform these activities on satisfactory terms. If our marketing, sales and distribution strategy is unsuccessful, our ability to sell our products will be negatively impacted and our revenues will decrease. The market for companion animal healthcare products is highly fragmented. Because our Core Companion Animal Health proprietary products are generally available only to veterinarians or by prescription and our medical instruments require technical training to operate, we ultimately sell our Core Companion Animal Health products only to or through veterinarians. The acceptance of our products by veterinarians is critical to our success. Changes in our ability to obtain or maintain such acceptance or changes in veterinary medical practice could significantly decrease our anticipated sales. We currently sell most of our Core Companion Animal Health products in the United States to veterinarians through an outside sales force of approximately 29 individuals, an inside sales force of approximately 23 individuals, approximately 11 independent third-party distributors who carry our full distribution line and approximately 7 independent third-party distributors who carry portions of our distribution line. To be successful in these endeavors, we will have to effectively market our products and continue to develop and train our direct sales force as well as sales personnel of our independent third-party distributors. Independent third party distributors may be effective in increasing sales of our products to veterinarians, although we would expect a corresponding lower gross margin as such distributors typically buy products from us at a discount to end user prices. It is possible new or existing independent third party distributors could cannibalize our direct sales efforts and lower our total gross margin. To be effective when working with an independent third party distributor, the distributor must agree to market and/or sell our products and we must provide proper economic incentives to the distributor as well as contend effectively for the distributor’s time and focus given other products the distributor may be carrying, potentially including those of our competitors. If we fail to be effective with new or existing independent third party distributors, our financial performance may suffer. In addition, most of our independent third party distributor agreements can be terminated on 60 days notice and we believe that IDEXX, one of our largest competitors, in effect prohibits its distributors from selling competitive products, including our diagnostic instruments and heartworm diagnostic tests. We believe this restriction limits our ability to engage national independent third party distributors to sell our full distribution line of products. In 2002, one of our largest distributors informed us that they were going to carry IDEXX products and that they no longer would carry our diagnostic instruments and heartworm diagnostic tests. In late 2004, this distributor acquired another of our distributors. We believe IDEXX in effect prohibits this distributor from carrying our diagnostic instruments and heartworm diagnostic tests as a condition for having access to buy the IDEXX product line. In the second quarter of 2005, one of our distributors purchased an IDEXX distributor and subsequently informed us that they no longer would carry our instruments and heartworm diagnostic tests. We believe IDEXX in effect prohibits this distributor from carrying our diagnostic instruments and heartworm diagnostic tests as a condition for having access to buy the IDEXX product line. 13 We rely substantially on third-party suppliers. The loss of products or delays in product availability from one or more third-party supplier could substantially harm our business. To be successful, we must contract for the supply of, or manufacture ourselves, current and future products of appropriate quantity, quality and cost. Such products must be available on a timely basis and be in compliance with any regulatory requirements. Failure to do so could substantially harm our business. We rely on third party suppliers to manufacture those products we do not manufacture ourselves. Proprietary products provided by these suppliers represent a majority of our product revenue. We currently rely on these suppliers for our veterinary instruments and consumable supplies for these instruments, for our point-of-care diagnostic and other tests, for the manufacture of our allergy immunotherapy treatment products as well as for the manufacture of other products. Major suppliers who sell us proprietary products which are responsible for more than 5% or more of our revenue are Arkray, Boule, i-STAT Corporation (currently a unit of Abbott Laboratories which is to be sold to General Electric Company based on a January 17, 2007 announcement) and Quidel. None of these suppliers sell us proprietary products which are responsible for more than 20% of our revenue, although the proprietary products of one is responsible for more than 15% of our revenue and two others are each responsible for more than 10% of our revenue. We often purchase products from our suppliers under agreements that are of limited duration or potentially can be terminated on an annual basis. In the case of our veterinary diagnostic instruments, we are typically entitled to non-exclusive access to consumable supplies for a defined period upon expiration of exclusive rights, which could subject us to competitive pressures in the period of non-exclusive access. Although we believe we have agreements in place to ensure supply of our major product offerings in the marketplace through at least the end of 2007 and we believe we are in compliance with such agreements, there can be no assurance that our suppliers will meet their obligations under these agreements or that we will be able to compel them to do so. Risks of relying on suppliers include: · The loss of product rights upon expiration or termination of an existing agreement. Unless we are able to find an alternate supply of a similar product, we would not be able to continue to offer our customers the same breadth of products and our sales and operating results would likely suffer. In the case of an instrument supplier, we could also potentially suffer the loss of sales of consumable supplies, which would be significant in cases where we have built a significant installed base, further harming our sales prospects and opportunities. Even if we were able to find an alternate supply, we would likely face increased competition from the product whose rights we lost being marketed by a third party or the former supplier and it may take us additional time and expense to gain the necessary approvals and launch an alternative product. · High switching costs. In certain of our diagnostic instrument products we would lose the consumable revenues from the installed base of those instruments if we were to switch to a competitive instrument. If we need to change to other commercial manufacturing contractors for certain of our regulated products, additional regulatory licenses or approvals must be obtained for these contractors prior to our use. This would require new testing and compliance inspections prior to sale thus resulting in potential delays. Any new manufacturer would have to be educated in, or develop substantially equivalent processes necessary for the production of our products. We likely would have to train our sales force, distribution network employees and customer support organization on the new product and spend significant funds marketing the new product to our customer base. · Loss of exclusivity. Current agreements, or agreements we may negotiate in the future, with suppliers may require us to meet minimum annual sales levels to maintain our position as the exclusive distributor of these products. We may not meet these minimum sales levels in the 14 future and maintain exclusivity over the distribution and sale of these products. If we are not the exclusive distributor of these products, competition may increase significantly, reducing our revenues and/or decreasing our margins. · Inability to meet minimum obligations. Current agreements, or agreements we may negotiate in the future, may commit us to certain minimum purchase or other spending obligations. It is possible we will not be able to create the market demand to meet such obligations, which could create a drain on our financial resources and liquidity. Some such agreements may require minimum purchases and/or sales to maintain product rights and we may be significantly harmed if we are unable to meet such requirements and lose product rights. · The involuntary or voluntary discontinuation of a product line. Unless we are able to find an alternate supply of a similar product in this or similar circumstances with any product, we would not be able to continue to offer our customers the same breadth of products and our sales would likely suffer. Even if we are able to identify an alternate supply, it may take us additional time and expense to gain the necessary approvals and launch an alternative product, especially if the product is discontinued unexpectedly. An example of such a situation arose in 2006 when Dolphin Medical Inc. (a majority-owned subsidiary of OSI Systems, Inc.) discontinued production of our VET/OX G2 DIGITAL Monitor as part of an agreement with Masimo Corporation to settle a patent dispute. · Limited capacity or ability to scale capacity. If market demand for our products increases suddenly, our current suppliers might not be able to fulfill our commercial needs, which would require us to seek new manufacturing arrangements and may result in substantial delays in meeting market demand. If we consistently generate more demand for a product than a given supplier is capable of handling, it could lead to large backorders and potentially lost sales to competitive products that are readily available. This could require us to seek or fund new sources of supply, which may be difficult to find unless it is under terms that are less advantageous. · Inconsistent or inadequate quality control. We may not be able to control or adequately monitor the quality of products we receive from our suppliers. Poor quality items could damage our reputation with our customers. · Regulatory risk. Our manufacturing facility and those of some of our third party suppliers are subject to ongoing periodic unannounced inspection by regulatory authorities, including the FDA, USDA and other federal and state agencies for compliance with strictly enforced Good Manufacturing Practices, regulations and similar foreign standards, and we do not have control over our suppliers’ compliance with these regulations and standards. Violations could potentially lead to interruptions in supply that could cause us to lose sales to readily available competitive products. · Developmental delays. We may experience delays in the scale-up quantities needed for product development that could delay regulatory submissions and commercialization of our products in development, causing us to miss key opportunities. · Limited intellectual property rights. We may not have intellectual property rights, or may have to share intellectual property rights, to the products themselves and any improvements to the manufacturing processes or new manufacturing processes for our products. Potential problems with suppliers such as those discussed above could substantially decrease sales, lead to higher costs, damage our reputation with our customers due to factors such as poor quality goods or 15 delays in order fulfillment, resulting in our being unable to effectively sell our products and substantially harm our business. We operate in a highly competitive industry, which could render our products obsolete or substantially limit the volume of products that we sell. This would limit our ability to compete and achieve profitability. The market in which we compete is intensely competitive. Our competitors include independent animal health companies and major pharmaceutical companies that have animal health divisions. We also compete with independent, third party distributors, including distributors who sell products under their own private labels. In the point-of-care diagnostic testing market, our major competitors include IDEXX, Abaxis, Inc. and Synbiotics Corporation. The products manufactured by our OVP segment for sale by third parties compete with similar products offered by a number of other companies, some of which have substantially greater financial, technical, research and other resources than us and may have more established marketing, sales, distribution and service organization’s than our OVP segment’s customers. Competitors may have facilities with similar capabilities to our OVP segment, which they may operate at a lower unit price to their customers, which could cause us to lose customers. Companies with a significant presence in the companion animal health market, such as Bayer AG, Intervet International bv (a unit of Akzo Nobel N.V.), Merial Limited, Novartis AG, Pfizer Inc., Schering-Plough Corporation, Virbac S.A. and Wyeth, may be marketing or developing products that compete with our products or would compete with them if developed. These and other competitors and potential competitors may have substantially greater financial, technical, research and other resources and larger, more established marketing, sales, distribution and service organizations than we do. Our competitors may offer broader product lines and have greater name recognition than we do. Our competitors may develop or market technologies or products that are more effective or commercially attractive than our current or future products or that would render our technologies and products obsolete. Further, additional competition could come from new entrants to the animal health care market. Moreover, we may not have the financial resources, technical expertise or marketing, distribution or support capabilities to compete successfully. We believe that one of our largest competitors, IDEXX, in effect prohibits its distributors from selling competitive products, including our diagnostic instruments and heartworm diagnostic tests. If we fail to compete successfully, our ability to achieve sustained profitability will be limited and sustained profitability, or profitability at all, may not be possible. If the third parties to whom we granted substantial marketing rights for certain of our existing products or future products under development are not successful in marketing those products, then our sales and financial position may suffer. Our agreements with our corporate marketing partners generally contain no or small minimum purchase requirements in order for them to maintain their exclusive or co-exclusive marketing rights. We are party to an agreement with SPAH which grants distribution and marketing rights in the U.S. for our canine heartworm preventive product, TRI-HEART Plus Chewable Tablets. AgriLabs has the exclusive right to sell certain of our bovine vaccines in the United States, Africa, China, Mexico and Taiwan. Novartis Japan markets and distributes our SOLO STEP CH heartworm test in Japan under an exclusive arrangement and has exclusive rights to our TRI-HEART Plus Chewable Tablets in Japan. One or more of these marketing partners may not devote sufficient resources to marketing our products. Furthermore, there may be nothing to prevent these partners from pursuing alternative technologies or products that may compete with our products in current or future agreements. In the future, third-party marketing assistance may not be available on reasonable terms, if at all. If any of these events occur, we may not be able to commercialize our products and our sales will decline. In addition, both our agreements with SPAH and AgriLabs require us to potentially pay penalties if we are unable to supply product over an extended period of time. 16 We often depend on third parties for products we intend to introduce in the future. If our current relationships and collaborations are not successful, we may not be able to introduce the products we intend to in the future. We are often dependent on third parties and collaborative partners to successfully and timely perform research and development activities to successfully develop new products. For example, we jointly developed point-of-care diagnostic products with Quidel. In other cases, we have discussed Heska marketing in the veterinary market an instrument being developed by a third party for use in the human health care market. In the future, one or more of these third parties or collaborative partners may not complete research and development activities in a timely fashion, or at all. Even if these third parties are successful in their research and development activities, we may not be able to come to an economic agreement with them. If these third parties or collaborative partners fail to complete research and development activities, fail to complete them in a timely fashion, or if we are unable to negotiate economic agreements with such third parties or collaborative partners, our ability to introduce new products will be impacted negatively and our revenues may decline. Our stock price has historically experienced high volatility, which may increase in the future, and which could affect our ability to raise capital in the future or make it difficult for investors to sell their shares. The securities markets have experienced significant price and volume fluctuations and the market prices of securities of many microcap and smallcap companies have in the past been, and can in the future be expected to be, especially volatile. During the past 12 months, our closing stock price has ranged from a low of $1.01 to a high of $1.86. Fluctuations in the trading price or liquidity of our common stock may adversely affect our ability to raise capital through future equity financings. Factors that may have a significant impact on the market price and marketability of our common stock include: · stock sales by large stockholders or by insiders; · our quarterly operating results, including as compared to our revenue, earnings or other guidance and in comparison to historical results; · termination of our third party supplier relationships; · announcements of technological innovations or new products by our competitors or by us; · litigation; · regulatory developments, including delays in product introductions; · developments in our relationships with collaborative partners; · developments or disputes concerning patents or proprietary rights; · availability of our revolving line of credit and compliance with debt covenants; · releases of reports by securities analysts; · changes in regulatory policies; · economic and other external factors; and · general market conditions. In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been instituted. If a securities class action suit is filed against us, it is likely 17 we would incur substantial legal fees and our management’s attention and resources would be diverted from operating our business in order to respond to the litigation. Our future revenues depend on successful research, development, commercialization and/or market acceptance, any of which can be slower than we expect or may not occur. The research, development and regulatory approval process for many of our potential products is extensive and may take substantially longer than we anticipate. Research projects may fail. New products that we are developing for the veterinary marketplace may not perform up to our expectations. Because we have limited resources to devote to product development and commercialization, any delay in the research or development of one product or reallocation of resources to product development efforts that prove unsuccessful may delay or jeopardize the development of other product candidates. If we fail to successfully develop new products and bring them to market in a timely manner, our ability to generate additional revenue will decrease. Even if we are successful in the research and development of a product, we may experience delays in commercialization and/or market acceptance. For example, veterinarians may be slow to adopt a product or there may be delays in producing large volumes of a product. The former is particularly likely where there is no comparable product available or historical use of such a product. For example, while we believe our E.R.D.-HEALTHSCREEN urine tests for dogs and cats represent a significant scientific breakthrough in companion animal annual health examinations, these products have achieved significantly lower market acceptance than we anticipated. The ultimate adoption of a new product by veterinarians, the rate of such adoption and the extent veterinarians choose to integrate such a product into their practice are all important factors in the economic success of one of our new products and are factors that we do not control to a large extent. If our products do not achieve a significant level of market acceptance, demand for our products will not develop as expected and our revenues will be lower than we anticipate. Obtaining and maintaining regulatory approvals in order to market our regulated products may be costly and delay the marketing and sales of our products. Many of the products we develop, market or manufacture are subject to extensive regulation by one or more of the USDA, the FDA, the EPA and foreign regulatory authorities. These regulations govern, among other things, the development, testing, manufacturing, labeling, storage, pre-market approval, advertising, promotion, sale and distribution of some of our products. Satisfaction of these requirements can take several years and time needed to satisfy them may vary substantially, based on the type, complexity and novelty of the product. The effect of government regulation may be to delay or to prevent marketing of our products for a considerable period of time and to impose costly procedures upon our activities. We have experienced in the past, and may experience in the future, difficulties that could delay or prevent us from obtaining the regulatory approval or license necessary to introduce or market our products. Such delays in approval may cause us to forego a significant portion of a new product’s sales in its first year due to seasonality and advanced booking periods associated with certain products. Regulatory approval of our products may also impose limitations on the indicated or intended uses for which our products may be marketed. Among the conditions for certain regulatory approvals is the requirement that our facilities and/or the facilities of our third party manufacturers conform to current Good Manufacturing Practices. Our manufacturing facilities and those of our third party manufacturers must also conform to certain other manufacturing regulations, which include requirements relating to quality control and quality assurance as well as maintenance of records and documentation. The USDA, FDA and foreign regulatory authorities strictly enforce manufacturing regulatory requirements through periodic inspections. If any regulatory 18 authority determines that our manufacturing facilities or those of our third party manufacturers do not conform to appropriate manufacturing requirements, we or the manufacturers of our products may be subject to sanctions, including warning letters, manufacturing suspensions, product recalls or seizures, injunctions, refusal to permit products to be imported into or exported out of the United States, refusals of regulatory authorities to grant approval or to allow us to enter into government supply contracts, withdrawals of previously approved marketing applications, civil fines and criminal prosecutions. In addition, certain of our agreements require us to pay penalties if we are unable to supply products, including for failure to maintain regulatory approvals. Any of these events, alone or in unison, could damage our business. The loss of significant customers could harm our operating results. SPAH accounted for approximately 13% of our consolidated accounts receivable at December 31, 2006. No single customer accounted for more than 10% of our consolidated accounts receivable at December 31, 2005. While sales to no single customer accounted for more than 10% of consolidated revenue for the twelve month periods ended on December 31, 2006, December 31, 2005 and December 31, 2004, respectively, the loss of significant customers who, for example, are historically large purchasers or who are considered leaders in their field could damage our business and financial results. For example, Henry Schein, Inc. (“Henry Schein”) acquired NLS Animal Health (“NLS”) in the second quarter of 2006. Henry Schein was our largest independent third-party distributor at the time and NLS was a distributor of IDEXX products. We believe IDEXX in effect prohibits its distributors from selling competitive products, including our diagnostic instruments and heartworm diagnostic tests. Henry Schein subsequently informed us that they would no longer carry our diagnostic instruments and heartworm diagnostic tests. Henry Schein and we have agreed that Henry Schein will carry our products that do not compete directly with IDEXX under an amended distribution agreement. Henry Schein customers’ purchases of our products will likely decline as it is unlikely we will completely recover purchases by these customers through direct sales and sales to other distributors. We believe IDEXX in effect prohibits Henry Schein from carrying our diagnostic instruments and heartworm diagnostic tests as a condition for having access to buy the IDEXX product line. We may not be able to achieve sustained profitability. Prior to 2005, we have incurred net losses on an annual basis since our inception in 1988 and, as of December 31, 2006, we had an accumulated deficit of $208.0 million. 2005 and 2006 are the only years we have achieved positive net income, and we were not profitable in every quarter of these years. Our ability to be profitable in future periods will depend, in part, on our ability to increase sales in our Core Companion Animal Health segment, including maintaining and growing our installed base of instruments and related consumables, to maintain or increase gross margins and to limit the increase in our operating expenses to a reasonable level. Even if we achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. If we cannot achieve or sustain profitability for an extended period, we may not be able to fund our expected cash needs, including the repayment of debt as it comes due, or continue our operations. Our common stock is listed on the Nasdaq Capital Market and we may not be able to maintain that listing, which may make it more difficult for you to sell your shares. Our common stock is listed on the Nasdaq Capital Market. The Nasdaq has several quantitative and qualitative requirements companies must comply with to maintain this listing, including a $1.00 minimum bid price. While we believe we are currently in compliance with all Nasdaq requirements, we have not always been able to maintain compliance in the past and there can be no assurance we will maintain compliance in the future. For example, in 2005 we received two communications from Nasdaq advising us we had failed to comply with the minimum $1.00 per share bid price requirement and the $35 million minimum value of listed securities requirement, respectively. While we subsequently received communications from Nasdaq advising 19 us we have regained compliance in both matters and that both matters are now closed, there can be no assurance we will continue to meet these requirements or other requirements in the future. If we are delisted from the Nasdaq Capital Market, our common stock may be considered a penny stock under the regulations of the SEC and would therefore be subject to rules that impose additional sales practice requirements on broker-dealers who sell our securities. The additional burdens imposed upon broker-dealers may discourage broker-dealers from effecting transactions in our common stock, which could severely limit market liquidity of the common stock and your ability to sell our securities in the secondary market. This lack of liquidity would also make it more difficult for us to raise capital in the future. We may face costly legal disputes, including related to our intellectual property or technology or that of our suppliers or collaborators. We may face legal disputes related to our business. Even if meritless, these disputes may require significant expenditures on our part and could entail a significant distraction to members of our management team or other key employees. A legal dispute leading to an unfavorable ruling or settlement could have significant material adverse consequences on our business. We have United States and foreign-issued patents and are currently prosecuting patent applications in the United States and various foreign countries. Our pending patent applications may not result in the issuance of any patents or any issued patents that will offer protection against competitors with similar technology. Patents we receive may be challenged, invalidated or circumvented in the future or the rights created by those patents may not provide a competitive advantage. We also rely on trade secrets, technical know-how and continuing invention to develop and maintain our competitive position. Others may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets. We may become subject to additional patent infringement claims and litigation in the United States or other countries or interference proceedings conducted in the United States Patent and Trademark Office, or USPTO, to determine the priority of inventions. The defense and prosecution of intellectual property suits, USPTO interference proceedings, and related legal and administrative proceedings are costly, time-consuming and distracting. We may also need to pursue litigation to enforce any patents issued to us or our collaborative partners, to protect trade secrets or know-how owned by us or our collaborative partners, or to determine the enforceability, scope and validity of the proprietary rights of others. Any litigation or interference proceeding will result in substantial expense to us and significant diversion of the efforts of our technical and management personnel. Any adverse determination in litigation or interference proceedings could subject us to significant liabilities to third parties. Further, as a result of litigation or other proceedings, we may be required to seek licenses from third parties which may not be available on commercially reasonable terms, if at all. We license technology from a number of third parties. The majority of these license agreements impose due diligence or milestone obligations on us, and in some cases impose minimum royalty and/or sales obligations on us, in order for us to maintain our rights under these agreements. Our products may incorporate technologies that are the subject of patents issued to, and patent applications filed by, others. As is typical in our industry, from time to time we and our collaborators and suppliers have received, and may in the future receive, notices from third parties claiming infringement and invitations to take licenses under third party patents. While we currently do not have any unresolved notices of infringement, there is no assurance that there will be none in the future. Any legal action against us or our collaborators and suppliers may require us or our collaborators and suppliers to obtain one or more licenses in order to market or manufacture affected products or services. However, we or our collaborators and suppliers may not be able to obtain licenses for technology patented by others on commercially reasonable terms, or at all, may not be able to develop alternative approaches if unable to obtain licenses, or current and future licenses may not be adequate 20 for the operation of our businesses. An example of such a situation arose in 2006 when Dolphin Medical Inc. (a majority-owned subsidiary of OSI Systems, Inc.) discontinued production of our VET/OX G2 DIGITAL Monitor as part of an agreement with Masimo Corporation to settle a patent dispute. Failure to obtain necessary licenses or to identify and implement alternative approaches could prevent us and our collaborators and suppliers from commercializing our products under development and could substantially harm our business. Interpretation of existing legislation, regulations and rules or implementation of future legislation, regulations and rules could cause our costs to increase or could harm us in other ways. The Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”) has increased our required administrative actions as a public company. The increase in general and administrative costs of complying with Sarbanes-Oxley will depend on how it is interpreted over time. Of particular concern are the level and timing of standards for internal control evaluation and reporting adopted under Section 404 of Sarbanes-Oxley. If our regulators and/or auditors adopt or interpret more stringent standards than we are anticipating, we and/or our auditors may be unable to conclude that our internal controls over financial reporting are designed and operating effectively, which could adversely affect investor confidence in our financial statements. Even if we and our auditors are able to conclude that our internal controls over financial reporting are designed and operating effectively in such a circumstance, our general and administrative costs are likely to increase. We may be required to obtain an audit of our internal controls as of December 31, 2007 and are currently required to obtain an audit of our internal controls as of December 31, 2008. Thus, our general and administrative costs are likely to increase in the future. In addition, actions by other entities, such as enhanced rules to maintain our listing on the Nasdaq Capital Market, could also increase our general and administrative costs or have other adverse effects on us, as could further legislative, regulatory or rule-making action or more stringent interpretations of existing legislation, regulations and rules. Many of our expenses are fixed and if factors beyond our control cause our revenue to fluctuate, this fluctuation could cause greater than expected losses, cash flow and liquidity shortfalls. We believe that our future operating results will fluctuate on a quarterly basis due to a variety of factors which are generally beyond our control, including: · supply of products from third party suppliers or termination of such relationships; · the introduction of new products by our competitors or by us; · competition and pricing pressures from competitive products; · our ability to maintain relationships with independent third party distributors; · large customers failing to purchase at historical levels, including changes in independent third party distributor purchasing patterns and inventory levels; · fundamental shifts in market demand; · manufacturing delays; · shipment problems; · regulatory and other delays in product development; · product recalls or other issues which may raise our costs; · changes in our reputation and/or market acceptance of our current or new products; and · changes in the mix of products sold. 21 We have high operating expenses for personnel and marketing. Many of these expenses are fixed in the short term. If any of the factors listed above cause our revenues to decline, our operating results could be substantially harmed. If we are unable to maintain various financial and other covenants under our credit facility agreement we will be unable to borrow any funds under the agreement and fund our operations. Under our credit and security agreement with Wells Fargo Bank, National Association (“Wells Fargo”), as amended and restated in December 2005 and under prior agreements, we are required to comply with various financial and non-financial covenants in order to borrow under the agreement. The availability of borrowings under this agreement is essential to continue to fund our operations. Among the financial covenants is a requirement to maintain minimum liquidity (cash plus excess borrowing base) of $1.5 million. Additional requirements include covenants for minimum capital monthly and minimum net income quarterly. Although we believe we will be able to maintain compliance with all these covenants and any covenants we may negotiate in the future, there can be no assurance thereof. We have not always been able to maintain compliance with all covenants in the past. Although Wells Fargo granted us a waiver of non-compliance in each case, there can be no assurance we will be able to obtain similar waivers or other modifications if needed in the future on economic terms, if at all. Failure to comply with any of the covenants, representations or warranties, or failure to modify them to allow future compliance, could result in our being in default under the loan and could cause all outstanding amounts and loans with our other lenders to become immediately due and payable, or impact our ability to borrow under the agreement. We intend to rely on available borrowings under the credit and security agreement to fund our operations in the future. If we are unable to borrow funds under this agreement, we will need to raise additional capital from other sources to continue our operations, which capital may not be available on acceptable terms, or at all. We have historically not consistently generated positive cash flow from operations and may need additional capital and any required capital may not be available on acceptable terms or at all. If our actual performance deviates from our operating plan, which anticipates we will be profitable in fiscal 2007, we may be required to raise additional capital in the future. If necessary, we expect to raise these additional funds by the sale of equity or debt securities or refinancing loans currently outstanding on assets with historical appraised values in excess of related debt. There is no guarantee that additional capital will be available from these sources on acceptable terms, if at all, and certain of these sources may require approval by existing lenders. The public markets may be unreceptive to equity financings and we may not be able to obtain additional private equity or debt financing. Any equity financing would likely be dilutive to stockholders and additional debt financing, if available, may include restrictive covenants and increased interest rates that would limit our currently planned operations and strategies. If we relinquish rights to certain of our intellectual property, or sell certain of our assets, products or marketing rights it may limit our future prospects. Additionally, amounts we expect to be available under our existing revolving line of credit may not be available and other lenders could refuse to provide us with additional debt financing. Furthermore, even if additional capital is available, it may not be of the magnitude required to meet our needs under these or other scenarios. If additional funds are required and are not available, it would likely have a material adverse effect on our business, financial condition and our ability to continue as a going concern. 22 We depend on key personnel for our future success. If we lose our key personnel or are unable to attract and retain additional personnel, we may be unable to achieve our goals. Our future success is substantially dependent on the efforts of our senior management and other key personnel. The loss of the services of members of our senior management or other key personnel may significantly delay or prevent the achievement of our business objectives. Although we have an employment agreement with many of these individuals, all are at-will employees, which means that either the employee or Heska may terminate employment at any time without prior notice. If we lose the services of, or fail to recruit, key personnel, the growth of our business could be substantially impaired. We do not maintain key person life insurance for any of our senior management or key personnel. Changes to financial accounting standards may affect our results of operations and cause us to change our business practices. We prepare our financial statements in conformance with United States generally accepted accounting principles, or GAAP. These accounting principles are established by and are subject to interpretation by the Financial Accounting Standards Board, the American Institute of Certified Public Accountants, the SEC and various bodies formed to interpret and create appropriate accounting policies. A change in those policies can have a significant effect on our reported results and may affect our reporting of transactions completed before a change is made effective. Changes to those rules may adversely affect our reported financial results or the way we conduct our business. We may face product returns and product liability litigation in excess of or not covered by our insurance coverage. If we become subject to product liability claims resulting from defects in our products, we may fail to achieve market acceptance of our products and our sales could substantially decline. The testing, manufacturing and marketing of our current products as well as those currently under development entail an inherent risk of product liability claims and associated adverse publicity. Following the introduction of a product, adverse side effects may be discovered. Adverse publicity regarding such effects could affect sales of our other products for an indeterminate time period. To date, we have not experienced any material product liability claims, but any claim arising in the future could substantially harm our business. Potential product liability claims may exceed the amount of our insurance coverage or may be excluded from coverage under the terms of the policy. We may not be able to continue to obtain adequate insurance at a reasonable cost, if at all. In the event that we are held liable for a claim against which we are not indemnified or for damages exceeding the $10 million limit of our insurance coverage or which results in significant adverse publicity against us, we may lose revenue, be required to make substantial payments which could exceed our financial capacity and/or lose or fail to achieve market acceptance. Furthermore, our agreements with some suppliers of our instruments contain limited warranty provisions, which may subject us to liability if a supplier fails to meet its warranty obligations if a defect is traced to our instrument or if we cannot correct errors reported during the warranty period. If our contractual limitations are unenforceable in a particular jurisdiction, a successful claim could require us to pay substantial damages. We may be held liable for the release of hazardous materials, which could result in extensive clean up costs or otherwise harm our business. Certain of our products and development programs produced at our Des Moines, Iowa facility involve the controlled use of hazardous and biohazardous materials, including chemicals, infectious disease agents and various radioactive compounds. Although we believe that our safety procedures for handling and disposing of such materials comply with the standards prescribed by applicable local, state and federal regulations, we cannot eliminate the risk of accidental contamination or injury from these materials. In the event of such an accident, we could be held liable for any fines, penalties, remediation costs or other damages 23 that result. Our liability for the release of hazardous materials could exceed our resources, which could lead to a shutdown of our operations, significant remediation costs and potential legal liability. In addition, we may incur substantial costs to comply with environmental regulations if we choose to expand our manufacturing capacity. Item 1B. Unresolved Staff Comments Not applicable. Item 2. Properties. Our principal administrative and research and development activities are located in Loveland, Colorado. We currently lease approximately 60,000 square feet at a facility in Loveland, Colorado under an 18-year lease agreement which expires in 2023. Our principal production facility located in Des Moines, Iowa, consists of 168,000 square feet of buildings on 34 acres of land, which we own. We also own a 175-acre farm used principally for testing products, located in Carlisle, Iowa. Our European facility in Fribourg, Switzerland is leased under an agreement which expires in 2012. Item 3. Legal Proceedings. From time to time, we may be involved in litigation relating to claims arising out of our operations. On September 9, 2005, United Vaccines, Inc. (“United”), a customer of our OVP segment, filed a lawsuit in Madison, Wisconsin against our Diamond Animal Health, Inc. subsidiary (“Diamond”) and Heska Corporation alleging various claims, including breach of contract and breach of warranty, and demanding compensatory and punitive damages. On October 20, 2005, we filed counterclaims on behalf of Diamond as well as a motion to dismiss all claims against Heska Corporation. United filed an amended complaint on November 16, 2005 and Diamond filed an amended counterclaim on January 25, 2006. The matter proceeded to a jury trial. On October 18, 2006, all remaining claims against Diamond and Heska Corporation were dismissed and United was found in breach of contract with corresponding damages owed to Diamond. In the course of the litigation, we discovered that United had dissolved as of December 29, 2005. We also came to believe that United had transferred substantially all its assets to an Indiana Domestic Limited Liability Company (“LLC”). On December 28, 2006, United filed a Notice of Appeal with the Seventh Circuit Court of Appeals. Under a settlement and release agreement effective March 23, 2007, United agreed to have approximately $1.6 million paid to Diamond for product Diamond had previously shipped to United and other contractual obligations and all other remaining claims involving this matter were waived. Item 4. Submission of Matters to a Vote of Security Holders. No matters were submitted to a vote of stockholders during the fourth quarter ended December 31, 2006. 24 PART II Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

Management’s Discussion and Analysis of Financial Condition and Results of Operations. The following discussion and analysis of our financial condition and results of operations should be read in conjunction with “Selected Consolidated Financial Data” and the Consolidated Financial Statements and related Notes included in Items 6 and 8 of this Form 10-K. This discussion contains forward-looking statements that involve risks and uncertainties. Such statements, which include statements concerning future revenue sources and concentration, gross profit margins, selling and marketing expenses, research and development expenses, general and administrative expenses, capital resources, additional financings or borrowings and additional losses, are subject to risks and uncertainties, including, but not limited to, those discussed below and elsewhere in this Form 10-K, particularly in Item 1A. “Risk Factors,” that could cause actual results to differ materially from those projected. The forward-looking statements set forth in this Form 10-K are as of March 30, 2007, and we undertake no duty to update this information. Overview We discover, develop, manufacture, market, sell, distribute and support veterinary products. Our business is comprised of two reportable segments, Core Companion Animal Health, which represented 83% of 2006 product revenue, and Other Vaccines, Pharmaceuticals and Products, previously reported as Diamond Animal Health, which represented 17% of 2006 product revenue. The Core Companion Animal Health segment (“CCA”) includes diagnostic and other instruments and supplies as well as single use diagnostic and other tests, vaccines and pharmaceuticals, primarily for canine and feline use. Diagnostic and other instruments and supplies represented approximately 45% of our 2006 product revenue. Many products in this area involve placing an instrument in the field and generating future revenue from consumables, including items such as supplies and service, as that instrument is used. Approximately 32% of our 2006 product revenue resulted from the sale of such consumables to an installed base of instruments and approximately 13% of our product revenue was from new hardware sales. A loss of or disruption in supply of consumables we are selling to an installed base of instruments could substantially harm our business. All products in this area are supplied by third parties, who typically own the product rights and supply the product to us under marketing and/or distribution agreements. In many cases, we have collaborated with a third party to adapt a human instrument for veterinary use. Major products in this area include our handheld electrolyte instrument, our chemistry instrument and our hematology instrument and their affiliated operating consumables. Revenue from products in these three areas, including revenue from consumables, represented approximately 40% of our 2006 product revenue. Single use diagnostic and other tests, vaccines and pharmaceuticals represented approximately 38% of our 2006 product revenue. Since items in this area are single use by their nature, our aim is to build customer satisfaction and loyalty for each product, generate repeat annual sales from existing customers and expand our customer base in the future. Products in this area are both supplied by third parties and provided by us. Major products in this area include our heartworm diagnostic tests, our heartworm preventive, our allergy immunotherapy, our allergy diagnostic tests and our allergy diagnostic kits. Combined revenue from heartworm-related products and allergy-related products represented approximately 35% of 2006 product revenue. We consider the Core Companion Animal Health segment to be our core business and devote most of our management time and other resources to improving the prospects for this segment. Maintaining a 28 continuing, reliable and economic supply of products we currently obtain from third parties is critical to our success in this area. Virtually all of our sales and marketing expenses are in the Core Companion Animal Health segment. The majority of our research and development spending is dedicated to this segment, as well. We strive to provide high value products and advance the state of veterinary medicine. All our Core Companion Animal Health products are ultimately sold to or through veterinarians. In many cases, veterinarians will mark up their costs to the end user. The acceptance of our products by veterinarians is critical to our success. Core Companion Animal Health products are sold directly by us as well as through independent third party distributors and other distribution relationships, such as corporate agreements. Revenue from direct sales, independent third-party distributors and other distribution relationships represented approximately 51%, 26% and 23% of Core Companion Animal Health 2006 product revenue, respectively. Independent third-party distributors may be effective in increasing sales of our products to veterinarians, although we would expect a corresponding lower gross margin as such distributors typically buy products from us at a discount to end user prices. To be effective when working with an independent third-party distributor, the distributor must agree to market and/or sell our products and we must provide proper economic incentives to the distributors as well as contend effectively for the distributor’s time and focus given other products the distributor may be carrying, potentially including those of our competitors. We believe that one of our largest competitors, IDEXX, in effect prohibits its distributors from selling competitive products, including our diagnostic instruments and heartworm diagnostic tests. We believe the IDEXX restrictions limit our ability to engage national distributors to sell our full distribution line of products. We intend to sustain profitability through a combination of revenue growth, gross margin improvement and expense control. Accordingly, we closely monitor product revenue growth trends in our Core Companion Animal Health segment. Product revenue in this segment grew 10% in 2006 as compared to 2005 and has grown at a compounded annual growth rate of 19% since 1998, our first full year as a public company. The Other Vaccines, Pharmaceuticals and Products segment (“OVP”) includes our 168,000 square foot USDA- and FDA-licensed production facility in Des Moines, Iowa. We view this facility as a strategic asset which will allow us to control our cost of goods on any vaccines and pharmaceuticals that we may commercialize in the future. We are increasingly integrating this facility with our operations elsewhere. For example, virtually all our U.S. inventory is now stored at this facility and fulfillment logistics are managed there. CCA segment products manufactured at this facility are transferred at cost and are not recorded as revenue for our OVP segment. We view OVP reported revenue as revenue primarily to cover the overhead costs of the facility and to generate incremental cash flow to fund our Core Companion Animal Health segment. Our OVP segment includes private label vaccine and pharmaceutical production, primarily for cattle but also for other animals including small mammals and fish. All OVP products are sold by third parties under third party labels. We have developed our own line of bovine vaccines that are licensed by the USDA. We have a long-term agreement with a distributor, Agri Laboratories, Ltd., (“AgriLabs”), for the marketing and sale of certain of these vaccines which are sold primarily under the TitaniumÒ and MasterGuardÒ brands which are registered trademarks of AgriLabs. This agreement generates a significant portion of our OVP segment’s revenue. Subject to certain purchase minimums, under our long term agreement, AgriLabs has the exclusive right to sell the aforementioned bovine vaccines in the United States, Africa, China, Mexico and Taiwan until 29 at least December 2009. This exclusivity may be extended under certain conditions. Our OVP segment also produces vaccines and pharmaceuticals for other third parties. Additionally, we generate non-product revenues from sponsored research and development projects for third parties, licensing of technology and royalties. We perform these sponsored research and development projects for both companion animal and livestock product purposes. Critical Accounting Policies and Estimates Our discussion and analysis of our financial condition and results of operations is based upon the consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenue and expense during the periods. These estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. We have identified those critical accounting policies used in reporting our financial position and results of operations based upon a consideration of those accounting policies that involve the most complex or subjective decisions or assessment. We consider the following to be our critical policies. Revenue Recognition We generate our revenue through the sale of products, licensing of technology product rights, royalties and sponsored research and development. Our policy is to recognize revenue when the applicable revenue recognition criteria have been met, which generally include the following: · Persuasive evidence of an arrangement exists; · Delivery has occurred or services rendered; · Price is fixed or determinable; and · Collectibility is reasonably assured. Revenue from the sale of products is recognized after both the goods are shipped to the customer and acceptance has been received, if required, with an appropriate provision for estimated returns and allowances. We do not permit general returns of products sold. Certain of our products have expiration dates. Our policy is to exchange certain outdated, expired product with the same product. We record an accrual for the estimated cost of replacing the expired product expected to be returned in the future, based on our historical experience, adjusted for any known factors that reasonably could be expected to change historical patterns, such as regulatory actions which allow us to extend the shelf life of our products. Revenue from both direct sales to veterinarians and sales to independent third-party distributors are generally recognized when goods are shipped. Our products are shipped complete and ready to use by the customer. The terms of the customer arrangements generally pass title and risk of ownership to the customer at the time of shipment. Certain customer arrangements provide for acceptance provisions. Revenue for these arrangements is not recognized until the acceptance has been received or the acceptance period has lapsed. We reduce our product revenue by the estimated cost of any rebates, allowances or similar programs, which are used as promotional programs. Recording revenue from the sale of products involves the use of estimates and management judgment. We must make a determination at the time of sale whether the customer has the ability to make payments in accordance with arrangements. While we do utilize past payment history, and, to the extent available for new customers, public credit information in making our 30 assessment, the determination of whether collectibility is reasonably assured is ultimately a judgment decision that must be made by management. We must also make estimates regarding our future obligation relating to returns, rebates, allowances and similar other programs. License revenue under arrangements to sell or license product rights or technology rights is recognized as obligations under the agreement are satisfied, which generally occurs over a period of time. Generally, licensing revenue is deferred and recognized over the estimated life of the related agreements, products, patents or technology. Nonrefundable licensing fees, marketing rights and milestone payments received under contractual arrangements are deferred and recognized over the remaining contractual term using the straight-line method. Revenue from licensing technology and product rights is reported in our Research, development and other revenue line item. An example of the former, i.e. licensing technology, is a patent we own under which we have granted a third-party exclusive rights to the human healthcare market for the life of the patent in exchange for an upfront payment and royalty payments on sales of any product based on the patent. The upfront payment will be amortized over the life of the patent and reported along with any affiliated royalty payments in our Research, development and other revenue line item. An example of the latter, i.e. product rights, is our July 2002 agreement to license Intervet Inc. certain rights to patents, trademarks and know-how for our Flu AVERT I.N. equine influenza vaccine, the world’s first intranasal influenza vaccine for horses. As we have no further rights to manufacture, market or sell this vaccine without Intervet Inc.’s permission, we are reporting the amortization of the upfront payment we received in this agreement along with any affiliated royalty payments in our Research, development and other revenue line item. The upfront payment is being amortized over the estimated life of the product. Recording revenue from license arrangements involves the use of estimates. The primary estimate made by management is determining the useful life of the related agreement, product, patent or technology. We evaluate all of our licensing arrangements by estimating the useful life of either the product or the technology, the length of the agreement or the legal patent life and defer the revenue for recognition over the appropriate period. Occasionally we enter into arrangements that include multiple elements. Such arrangements may include the licensing of technology and manufacturing of product. In these situations we must determine whether the various elements meet the criteria to be accounted for as separate elements. If the elements cannot be separated, revenue is recognized once revenue recognition criteria for the entire arrangement have been met or over the period that the Company’s obligations to the customer are fulfilled, as appropriate. If the elements are determined to be separable, the revenue is allocated to the separate elements based on relative fair value and recognized separately for each element when the applicable revenue recognition criteria have been met. In accounting for these multiple element arrangements, we must make determinations about whether elements can be accounted for separately and make estimates regarding their relative fair values. Allowance for Doubtful Accounts We maintain an allowance for doubtful accounts receivable based on client-specific allowances, as well as a general allowance. Specific allowances are maintained for clients which are determined to have a high degree of collectibility risk based on such factors, among others, as: (i) the aging of the accounts receivable balance; (ii) the client’s past payment experience; (iii) a deterioration in the client’s financial condition, evidenced by weak financial condition and/or continued poor operating results, reduced credit ratings, and/or a bankruptcy filing. In addition to the specific allowance, the Company maintains a general allowance for credit risk in its accounts 31 receivable which is not covered by a specific allowance. The general allowance is established based on such factors, among others, as: (i) the total balance of the outstanding accounts receivable, including considerations of the aging categories of those accounts receivable; (ii) past history of uncollectible accounts receivable write-offs; and (iii) the overall creditworthiness of the client base. A considerable amount of judgment is required in assessing the realizability of accounts receivable. Should any of the factors considered in determining the adequacy of the overall allowance change, an adjustment to the provision for doubtful accounts receivable may be necessary. Inventories Inventories are stated at the lower of cost or market, cost being determined on the first-in, first-out method. Inventories are written down if the estimated net realizable value of an inventory item is less than its recorded value. We review the carrying cost of our inventories by product each quarter to determine the adequacy of our reserves for obsolescence. In accounting for inventories we must make estimates regarding the estimated net realizable value of our inventory. This estimate is based, in part, on our forecasts of future sales and shelf life of product. Capitalized Patent Costs In the years ended December 31, 2004, 2005 and 2006, we deferred and capitalized certain costs, including payments to third-party law firms for patent prosecution to expand the scope of our patents, related to the technology or patents underlying a variety of long-term licensing agreements. We owned a portfolio of patents not then utilized in our product development or manufacture. Several entities paid upfront licensing fees to utilize the technology supported by these patents in their own product development and commercialization efforts. Because we believed that we had an obligation to protect the underlying patents, we deferred the revenue associated with these long-term agreements and the direct and incremental costs of prosecuting the patents that supported the agreements. We use the term “patent prosecution” in this context in the narrow sense often used by intellectual property professionals — to describe activities where we seek to expand the scope of existing patents such as geographically, where we may look to expand patent protection into new countries, or for broader applications, such as for newly contemplated uses or expanded claim breadth coverage of the technology defined by those licensing our technology within existing geographies. A situation where a third party has violated our intellectual property rights by using our patented technology without permission and we have filed a corresponding lawsuit would not meet this definition of “patent prosecution” and we would therefore expense the corresponding legal expenses as incurred. In accordance with SFAS No. 95, paragraph 17(c), we classified patent prosecution expenditures which were capitalized as cash used for investing activities since, like a capital expenditure to improve a building or add a piece of equipment, the cost is a necessary investment into a productive asset to maintain our future revenue process. No internal costs were capitalized. These capitalized costs were amortized over the same period as the licensing revenue related to those patents was recognized. Costs in excess of the amount of remaining related deferred licensing revenue were not capitalized, but expensed as incurred. We capitalized approximately $292 thousand, $187 thousand and $541 thousand for the years ended December 31, 2006, 2005 and 2004, respectively, and amortized approximately $334 thousand, $157 thousand and $393 thousand for the same periods, respectively. In December 2006, we sold all patents for which we had capitalized patent costs and, accordingly, we have no capitalized patent costs on our balance sheet as of December 31, 2006. We do not expect to capitalize any patent costs in the future. Deferred Tax Assets – Valuation Allowance Our deferred tax assets, such as a net operating loss carryforward (“NOL”), are reduced by an offsetting valuation allowance based on judgmental assessment of available evidence if we are unable to conclude that it is more likely than not that some or all of the related deferred tax assets will be realized. If we are able to conclude it is more likely than not that we will realize a future benefit from an NOL, we will reduce the related valuation allowance by an amount equal to the estimated quantity of income taxes we would pay in cash if we were not to utilize our NOL in the future. The first time this occurs in a given jurisdiction, it will result in a net deferred tax asset on our balance sheet and an income tax benefit of equal magnitude in our statement of operations in the period we make the determination. In future periods, we will then recognize as income tax expense the estimated quantity of income taxes we would have paid in cash had we not utilized our NOL. The corresponding journal entry will be a reduction of our deferred tax asset. If there is a change regarding our tax position in the future, we will make a corresponding adjustment to the related valuation allowance. As an example, in 2005 we reduced our valuation allowance related to the NOL for our Swiss operating subsidiary which resulted in a net deferred tax asset on our balance sheet and we increased this valuation allowance based on agreements subsequently obtained from tax authorities in Switzerland in 2006. Our domestic NOL represents a deferred tax asset, which has been completely offset by a valuation allowance. Based on our domestic cumulative operating losses in recent years, as well as other factors including uncertainties regarding our future operations, we have been unable to conclude that it was more likely than not that we will realize a future benefit from our domestic NOL. Accordingly, a valuation allowance has been established for the entire domestic deferred tax asset at December 31, 2006. We expect to consider this situation throughout 2007. Should we conclude it is more likely than not that we will realize a future benefit from our domestic NOL, we likely would recognize a very large income tax benefit and a corresponding deferred tax asset on our balance sheet at that time. 32 Results of Operations The following table summarizes our results of operations for the three most recent fiscal years. 2004 Year Ended December 31, 2005 (in thousands except per share amounts) 2006 Consolidated Statement of Operations Data: Revenue: Product revenue, net: Core companion animal health Other vaccines, pharmaceuticals and products Total product revenue Research, development and other Total revenue, net Cost of revenue: Cost of products sold Cost of research, development and other Total cost of revenue: Gross profit Operating expenses: Selling and marketing Research and development General and administrative (Gain) on sale of assets Total operating expenses Income (loss) from operations Interest and other expense, net Income (loss) before income taxes Income tax expense (benefit) Net income (loss) Basic net income (loss) per share Diluted net income (loss) per share Revenue $ $ $ $ 52,719 12,968 65,687 2,004 67,691 42,253 729 42,982 24,709 15,616 5,891 7,442 — 28,949 (4,240) 575 (4,815) — (4,815) (0.10) (0.10) $ $ $ $ 54,716 12,833 67,549 1,888 69,437 42,515 1,095 43,610 25,827 14,020 3,749 7,187 — 24,956 871 774 97 (185) 282 0.01 0.01 $ $ $ $ 59,936 11,879 71,815 3,245 75,060 43,000 1,414 44,414 30,646 14,356 3,483 9,887 (155) 27,571 3,075 1,041 2,034 206 1,828 0.04 0.03 Total revenue, which includes product revenue, research and development and other revenue, increased 8% to $75.1 million in 2006 compared to $69.4 million in 2005. Total revenue for 2005 increased 3% to $69.4 million from $67.7 million in 2004. Product revenue increased 6% to $71.8 million in 2006 compared to $67.5 million in 2005. Product revenue increased 3% to $67.5 million in 2005 compared to $65.7 million in 2004. Core Companion Animal Health segment product revenue increased 10% to $59.9 million in 2006 compared to $54.7 million in 2005. Key factors in the increase were higher sales of our instrument consumables, our heartworm preventive, our heartworm diagnostic tests and our IV pumps, somewhat offset by lower sales of our hematology instruments. 2005 product revenue from our Core Companion Animal Health segment increased 4% to $54.7 million compared to $52.7 million in 2004. Key factors in the increase were higher sales of our instrument consumables, our heartworm preventive and our microalbumin laboratory packs, the latter of which we began to sell in 2005, somewhat offset by lower sales of our hematology instruments due to an offer 33 to certain customers who had previously purchased a hematology analyzer to upgrade to our new hematology analyzer during 2004 which was not repeated in 2005, and of our heartworm diagnostic tests. Other Vaccines, Pharmaceuticals and Products segment (“OVP”) product revenue decreased 7% to $11.9 million in 2006 compared to $12.8 million in 2005. A key factor in the decline was lower sales of our bovine vaccines under our contract with AgriLabs, including purchases under this contract by Intervet Inc. which occurred in the first quarter of 2005 but not 2006, somewhat offset by increased sales of our bulk bovine biologicals. Intervet Inc. launched a line of bovine vaccines competitive with ours in 2005. 2005 product revenue from OVP decreased 1% to $12.8 million compared to $13.0 million in 2004. The decrease in 2005 was due to lower sales of small mammal vaccines, somewhat offset by increased sales of our bovine vaccines under our contract with AgriLabs and our fish vaccines. Revenue from research and development and other items increased by 72% to $3.2 million in 2006 from $1.9 million in 2005. This increase was primarily due to the acceleration of approximately $1.5 million in previously deferred licensing fees recognized upon completion of the sale of a worldwide patent portfolio covering a number of major allergens and the genes that encode them (the “Allergopharma Portfolio”) in December 2006. We recognized approximately $2.1 million in licensing revenue related to the Allergopharma Portfolio in 2006, including revenue from the amortization of previous upfront payments and other payments from third parties. While we have an exclusive veterinary license to the Allergopharma Portfolio and have a service agreement related to the Allergopharma Portfolio under which we expect to generate 2007 revenue, we expect a significant decline in revenue related to the Allergopharma Portfolio in 2007 as compared to 2006. The 2005 decrease of 6% to $1.9 million from $2.0 million in 2004 was primarily due to the reduced level of activity for research and development efforts for third parties. We recognized approximately $269 thousand and $175 thousand in 2005 and 2006, respectively, for the acceleration of deferred revenue related to terminated licensing agreements. In 2007, we expect continued growth in our Core Companion Animal Health segment. We anticipate 2007 OVP revenue of around $13.5 million, a slight increase as compared to 2006. We expect research, development and other revenue to be approximately $1.25 million in 2007, a significant decline when compared to 2006. Cost of Revenue Cost of revenue consists of two components: 1) cost of products sold and 2) cost of research, development and other revenue, both of which correspond to their respective revenue categories. Cost of revenue totaled $44.4 million for the twelve months ended December 31, 2006, a 2% increase as compared to $43.6 million for the corresponding period in 2005. Gross profit increased 19% to $30.6 million for 2006 as compared to $25.8 million in 2005. Gross Margin, i.e. gross profit divided by total revenue, increased to 40.8% for 2006 as compared to 37.2% in 2005. Cost of revenue totaled $43.6 million for 2005, a 2% increase as compared to $43.0 million for 2004. Gross profit increased 5% to $25.8 million for 2005 as compared to $24.7 million in 2004. Gross Margin increased to 37.2% for 2005 as compared to 36.5% in 2004. Cost of products sold increased 1% to $43.0 million in the twelve months ended December 31, 2006 from $42.5 million in 2005. Gross profit on product revenue increased 15% to $28.8 million for 2006 from $25.0 million in the prior year. Product Gross Margin, i.e. gross profit on product revenue divided by product revenue, increased to 40.1% in 2006 as compared to 37.1% in 2005. Key factors in the improvement were higher sales and margins in our heartworm preventive product, where we now have taken in house certain manufacturing operations we previously outsourced; higher sales and margins in our heartworm diagnostic 34 tests, where agreements under which we paid certain royalties expired in 2005 and 2006; and a greater proportion of product sales from instrument consumables, which typically have a higher than average gross margin. Cost of products sold increased 1% to $42.5 million in 2005 as compared to $42.3 million in 2004. Gross profit on product revenue increased 7% to $25.0 million for 2005 from $23.4 million in 2004. Product Gross Margin increased to 37.1% in 2005 as compared to 35.7% in 2004. Key factors in the improvement were higher sales and margins in our heartworm preventive product, where we now have taken in house certain manufacturing operations we previously outsourced and increased instrument consumable sales, which typically carry a higher than average gross margin, somewhat offset by certain supplier price increases resulting from a contract renegotiation in the second half of 2004. Cost of research, development and other revenue increased 29% to $1.4 million in the twelve months ended December 31, 2006 as compared to $1.1 million in 2005. Gross profit on research, development and other revenue increased 131% to $1.8 million for 2006 from $793 thousand in 2005. Other Gross Margin, i.e. gross profit on research, development and other revenue divided by research, development and other revenue, increased to 56.4% for 2006 as compared to 42.0% in 2005. The primary reason for the increase in gross margin was the acceleration of certain previously deferred upfront licensing fees which were recognized in 2006 due to the sale of the Allergopharma Portfolio in December 2006. Cost of research, development and other revenue increased 50% to $1.1 million in 2005 as compared to $729 thousand in 2004. Gross profit on research, development and other revenue decreased 38% to $793 thousand for the twelve months ended December 31, 2005 from $1.3 million in 2004. Other Gross Margin decreased to 42.0% for 2005 as compared to 63.6% in 2004. The primary reason for the decrease is a greater proportion of patent-related costs being expensed as incurred in 2005 rather than capitalized when compared to the prior year. We expect our gross margin on product sales will increase in 2007 as compared to 2006 as we expect to sell a greater proportion of total sales in relatively higher margin products. Operating Expenses Selling and marketing expenses increased by 2% to $14.4 million in 2006 compared to $14.0 million in 2005 primarily due to increased expenditures on marketing programs. Selling and marketing expenses decreased by 10% to $14.0 million in 2005 as compared to $15.6 million in 2004 primarily due to marketing spending related to the initial rollout of our new hematology instrument and greater outside consulting fees related to corporate branding in 2004. Research and development expenses decreased by 7% to $3.5 million in 2006 from $3.7 million in 2005. A key factor in the decline was lower personnel costs. Research and development expenses decreased by 36% to $3.7 million in 2005 from $5.9 million in 2004. Key factors in the decrease were lower personnel costs and spending on clinical trials. General and administrative expenses increased by 38% to $9.9 million in 2006 from $7.2 million in 2005. Key factors in the increase include increased compensation expense, primarily related to the accrual of our 2006 Management Incentive Plan (“MIP”) payouts and options granted to management which were expensed for accounting purposes in 2006 but not 2005, increased legal fees, primarily related to litigation with United Vaccines, Inc. (a former customer of our OVP segment), and increased rent expense. General and administrative expenses decreased by 3% to $7.2 million in 2005 from $7.4 million in 2004. Key factors in the decrease were lower consulting fees and legal fees, somewhat offset by an increase in rent expense. In 2006, we recognized a gain of approximately $155 thousand on the sale of the Allergopharma Portfolio. The gain is equal to the sales price less the net book value of the Allergopharma Portfolio, which included all of our unamortized capitalized patent costs. We had no similar transactions in 2005 or 2004. 35 In 2007, we expect total operating expenses to increase as compared to 2006. We expect operating expenses generally will increase more slowly than increases in revenue from existing operations. Interest and Other Expense, Net Interest expense increased to $1.2 million in 2006 from $1.1 million in 2005 and $690 thousand in 2004. The increase in 2006 as compared to 2005 primarily reflects increased interest on borrowings under our credit and security agreement with Wells Fargo Bank, National Association (“Wells Fargo”) due to increases in Wells Fargo’s prime rate. The increase in 2005 as compared to 2004 reflects the greater usage of borrowings under our credit and security agreement with Wells Fargo, negotiated spread rate increases with Wells Fargo and increases in Wells Fargo’s prime rate. The 2005 increase in interest expense was partially offset by a $249 thousand gain in Other, net, primarily due to gains on foreign currency translation of approximately $224 thousand. This foreign currency gain resulted primarily from a transaction under which funds were transferred from Heska AG, our operating subsidiary in Switzerland, to the United States-based parent company via an intercompany receivable/payable and certain inventory transactions involving non-U.S. dollar currencies. Because this intercompany loan was to be repaid in the foreseeable future, changes in the amount of U.S. dollars receivable by Heska AG resulting from changes in foreign currency exchange rates are required to be recorded through earnings or loss. The impact of the foreign currency exchange rate changes resulted in a gain on the loan due to a strengthening U.S. dollar relative to the Swiss franc. We expect net interest expense to decrease in 2007 due to anticipated lower use of our revolving credit facility and lower interest rate spreads under our agreement with Wells Fargo. Income Tax Expense (Benefit) Historically, we have not been consistently profitable and, accordingly, have not recognized a tax benefit on our pre-tax losses. Based on the profitable operating performance of our operating subsidiary in Switzerland, Heska AG, in the fourth quarter of 2005 we concluded that our NOL in Switzerland was realizable on a more-likely-than-not basis. We reduced the related valuation allowance in the fourth quarter of 2005, resulting in an income tax benefit of approximately $185 thousand. This resulted in a net deferred tax asset of $185 thousand — equal to the estimated quantity of income taxes we would have recognized in our future statements of operations as income tax expense that we would not have to actually pay in cash as we utilized our NOL in Switzerland. We subsequently obtained agreements from the tax authorities in the canton of Fribourg regarding the determination of our taxable income which reduced our taxable income in Switzerland in 2005 and 2006 from previous estimates for financial reporting purposes and we expect to reduce our taxable income, and thus our tax obligation, in future years as compared to prior expectations. Given our corresponding lower income expectations in Switzerland, we no longer believe we will utilize all of our NOL in Switzerland before it fully expires at the end of 2008. Accordingly, we reduced our net deferred tax asset related to this NOL and recognized a corresponding income tax expense in the fourth quarter of 2006. In addition, we recognized approximately $58 thousand of income tax expense in the fourth quarter of 2006 related to alternative minimum tax obligations in the United States. We expect income tax expense to be less in 2007 than it was in 2006, primarily due to lower estimated taxable income in Switzerland as a result of the aforetomentioned agreements from the tax authorities in the canton of Fribourg. 36 Net Income (Loss) In 2006, we recorded the second consecutive year of profitability in our history. Our 2006 net income was $1.8 million as compared to $282 thousand in 2005 and an annual loss of $4.8 million in 2004. The 2006 improvement over 2005 was due to higher revenue and higher Gross Margin, somewhat offset by increased operating expenses. The improvement from 2004 to 2005 was due to increased product revenue, higher gross profit percentage on product sales, lower operating expenses and reversal of valuation allowances against our Swiss net operating loss deferred income tax assets for Heska AG. In 2007, we expect to increase our net income primarily due to increased revenue and increased gross margins somewhat offset by increased operating expenses. Liquidity, Capital Resources and Financial Condition We have incurred net cumulative negative cash flow from operations since inception in 1988. For the year ended December 31, 2006, we had total revenue of $75.1 million and net income of $1.8 million. In 2006, net cash provided by operations was $1.1 million. At December 31, 2006, we had $5.3 million of cash and cash equivalents, working capital of $8.7 million, $8.0 million of outstanding borrowings under our revolving line of credit, discussed below, and $3.2 million of other debt and capital leases. Net cash flows from operating activities provided cash of $1.1 million in 2006 as compared to $148 thousand in 2005 and using $1.1 million in 2004. The major factors in the improvement in our cash provided from operations in 2006 as compared to 2005 was a $3.7 million increase in cash from accrued liabilities, the largest component of which was approximately $1.5 million in anticipated payouts under our MIP which were accrued at year end 2006 as compared to no such anticipated payouts in 2005, a $1.5 million improvement in our net income, a $1.1 million improvement in cash used for accounts payable and an approximately $700 thousand increase in stock-based compensation recognized for accounting purposes but not paid in cash. The latter primarily relates to the adoption of a new accounting standard related to the expensing of stock options. These factors were somewhat offset by a $3.8 million greater usage of cash from accounts receivable, primarily related to our revenue growth, an approximately $1.5 million greater usage of cash for inventory purchases and an approximately $1.0 million greater usage of cash related to deferred revenue and other long-term liabilities, primarily related to our recognition of approximately $1.5 million in previously deferred licensing fees upon completion of the sale of the Allergopharma Portfolio in December 2006. Major factors in the improvement in our cash provided from operations in 2005 as compared to the net used in 2004 were a $5.1 million improvement in our net income and an approximately $1.4 million improvement in cash provided by inventory; these items were somewhat offset by a $2.1 million decrease in cash provided by deferred revenue and other long term liabilities, primarily related to an upfront payment received for marketing rights in 2004 not repeated in 2005, a $2.0 million decrease in cash provided by accounts payable and a $1.1 million dollar decrease in accrued liabilities. Net cash flows from investing activities provided cash of $159 thousand in 2006 as compared to using $1.5 million in 2005 and $1.4 million in 2004. Expenditures for property and equipment totaled approximately $1.2 million, $1.4 million and $1.3 million in 2006, 2005 and 2004, respectively. In 2006, the sale of certain intellectual property generated cash, after related costs, of approximately $1.6 million which was slightly larger than approximately $1.5 million in capital expenditures and capitalized patent costs. In 2004, approximately $1.8 million in capital expenditures and capitalized patent costs were somewhat offset by approximately $400 thousand of proceeds from the licensing of certain rights related to one of our products and $100 thousand of proceeds from the repayment of a loan. Net cash flows from financing activities used cash of $1.4 million in 2006 as compared to providing $1.8 million in 2005 and $2.5 million in 2004. In 2006, the Company reduced its line of credit borrowings by 37 $1.4 million and repaid principal on term debt of $763 thousand which was somewhat offset by $766 thousand in proceeds from the issuance of common stock upon option exercises and in our Employee Stock Purchase Plan. In 2005, the primary source of cash was $2.5 million from the Equipment Notes, somewhat offset by $922 thousand repayment of borrowings under our revolving line of credit with Wells Fargo. In 2004, the primary source of funds was $2.8 million in borrowings under our revolving credit facility. At December 31, 2006, we had a $12.0 million asset-based revolving line of credit with Wells Fargo which has a maturity date of June 30, 2009 as part of our credit and security agreement with Wells Fargo. At December 31, 2006, $8.0 million was outstanding under this line of credit. Our ability to borrow under this line of credit varies based upon available cash, eligible accounts receivable and eligible inventory. On December 31, 2006, interest on the term note was charged at a stated rate of prime plus 2.5% and was payable monthly. We are required to comply with various financial and non-financial covenants, and we have made various representations and warranties. Among the financial covenants is a requirement to maintain a minimum liquidity (cash plus excess borrowing base) of $1.5 million. Additional requirements include covenants for minimum capital monthly and minimum net income quarterly. Failure to comply with any of the covenants, representations or warranties could result in our being in default on the loan and could cause all outstanding amounts payable to Wells Fargo, including those discussed above, as well as our other borrowings, to become immediately due and payable or impact our ability to borrow under the agreement. Any default under the Wells Fargo agreement could also accelerate the repayment of our other borrowings. We were in compliance with all financial covenants as of December 31, 2006. At December 31, 2006, our remaining available borrowing capacity based upon eligible accounts receivable and eligible inventory under our revolving line of credit was approximately $4.0 million. At December 31, 2006, we also had outstanding obligations for long-term debt and capital leases totaling approximately $3.2 million primarily related to three term loans with Wells Fargo and a subordinated promissory note with a significant customer with the proceeds used for facilities enhancements. One term loan is secured by real estate in Iowa and had an outstanding balance at December 31, 2006 of approximately $693 thousand due in monthly installments of $17,658 plus interest, with a balloon payment of approximately $163 thousand due on June 30, 2009. The term loan had a stated interest rate of prime plus 2.5% on December 31, 2006. The other two term loans are secured by machinery and equipment at our Des Moines, Iowa and Loveland, Colorado locations (the “Equipment Notes”). The Equipment Notes had a stated interest rate of prime plus 2.5% on December 31, 2006. Principal payments on the Equipment Notes of $46,296 plus interest are due monthly with a balloon payment of approximately $602 thousand due upon maturity of the credit facility agreement on June 30, 2009. The subordinated promissory note is secured by our production facility, has a stated interest rate of prime plus 1.0% and a remaining balance of $500 thousand payable on May 31, 2007 and the lender has subordinated its first security interest to Wells Fargo. Our capital lease obligations totaled approximately $19 thousand at December 31, 2006. Based on certain provisions in our agreement with Wells Fargo, we expect the interest rate on all borrowings will be prime plus 1.0% in the first quarter of 2007 and prime for the remainder of 2007. At December 31, 2006, we had deferred revenue and other long term liabilities, net of current portion, of approximately $7.8 million. Included in this total is approximately $7.2 million of deferred revenue related to up-front fees that have been received for certain product rights and technology rights out-licensed. These deferred amounts are being recognized on a straight-line basis over the remaining lives of the agreements, products, patents or technology. Our primary short-term need for capital, which is subject to change, is to fund our operations, which consist of continued sales and marketing, general and administrative and research and development efforts, working capital associated with increased product sales and capital expenditures relating to maintaining and 38 developing our manufacturing operations. Our future liquidity and capital requirements will depend on numerous factors, including the extent to which our marketing, selling and distribution efforts, as well as those of third parties who market, sell and distribute our products, are successful in increasing revenue, the extent of the market acceptance of any new products, the extent to which currently planned products and/or technologies under research and development are successfully developed, changes required by us by regulatory bodies to maintain our operations and other factors. Our financial plan for 2007 indicates that our available cash and cash equivalents, together with cash from operations and borrowings expected to be available under our revolving line of credit, will be sufficient to fund our operations through 2007 and into 2008. Our financial plan for 2007 expects that we will have positive cash flow from operations, primarily through increased revenue, improved gross margins and limiting any increase in operating expenses to a modest degree. However, our actual results may differ from this plan, and we may be required to consider alternative strategies. We may be required to raise additional capital in the future. If necessary, we expect to raise these additional funds through the sale of equity or debt securities or refinancing loans currently outstanding on assets with historical appraised values significantly in excess of related debt. There is no guarantee that additional capital will be available from these sources on acceptable terms, if at all, and certain of these sources may require approval by existing lenders. If we cannot raise the additional funds through these options on acceptable terms or with the necessary timing, management could also reduce discretionary spending to decrease our cash burn rate through actions such as delaying or canceling budgeted research activities or marketing plans. These actions would likely extend the then available cash and cash equivalents, and then available borrowings. See “Risk Factors” In Item 1A. A summary of our contractual obligations at December 31, 2006 is shown below.

All milestone obligations which we believe are likely to be triggered but are not yet paid are included in “Unconditional Purchase Obligations” in the table above. We do not believe other potential milestone obligations, some of which we consider to be of remote likelihood of ever being triggered, will have a material impact on our liquidity, capital resources or financial condition in the foreseeable future. Net Operating Loss Carryforwards As of December 31, 2006, we had a net domestic operating loss carryforward, or NOL, of approximately $167.8 million, a domestic alternative minimum tax credit of approximately $81 thousand and a domestic research and development tax credit carryforward of approximately $307 thousand. The NOL and tax credit carryforwards are subject to alternative minimum tax limitations and to examination by the tax authorities. In addition, we had a “change of ownership” as defined under the provisions of Section 382 of the Internal Revenue Code of 1986, as amended (an “Ownership Change”). We believe the latest, and most restrictive, Ownership Change occurred at the time of our initial public offering in July 1997. We do not 39 believe this Ownership Change will place a significant restriction on our ability to utilize our NOLs in the future. We also have net operating loss carryforwards in Switzerland of approximately $1.9 million related to losses previously recorded by Heska AG. Heska AG also has a “tax holiday” from canton, municipal and church income taxes in the canton of Fribourg through August 31, 2007. Recent Accounting Pronouncements In February 2006, the FASB issued SFAS No. 155, “Accounting for Certain Hybrid Financial Instruments -an amendment of FASB Statements No. 133 and 140,” which simplifies accounting for certain hybrid financial instruments by permitting fair value remeasurement for any hybrid instrument that contains an embedded derivative that otherwise would require bifurcation and eliminates a restriction on the passive derivative instruments that a qualifying special-purpose entity may hold. SFAS No. 155 is effective for all financial instruments acquired, issued or subject to a remeasurement (new basis) event occurring after the beginning of an entity’s first fiscal year that begins after September 15, 2006. The adoption of SFAS No. 155 will have no impact on our results of operations or our financial position. In March 2006, the FASB issued SFAS No. 156, “Accounting for Servicing of Financial Assets - an amendment of FASB Statement No. 140,” which establishes, among other things, the accounting for all separately recognized servicing assets and servicing liabilities by requiring that all separately recognized servicing assets and servicing liabilities be initially measured at fair value, if practicable. SFAS No. 156 is effective as of the beginning of an entity’s first fiscal year that begins after September 15, 2006. The adoption of SFAS No. 156 will have no impact on our results of operations or our financial position. In June 2006, the FASB issued FASB Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109,” which establishes that the financial statement effects of a tax position taken or expected to be taken in a tax return are to be recognized in the financial statements when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. FIN 48 is effective for fiscal years beginning after December 15, 2006. The adoption of FIN 48 is not expected to have a material impact on our results of operations or our financial position. In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements,” which establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. SFAS No. 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The adoption of SFAS No. 157 is not expected to have a material impact on our results of operations or our financial position. In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans - an amendment of FASB Statements No. 87, 88, 106, and 132(R),” which requires a business entity to recognize the overfunded or underfunded status of a single- employer defined benefit postretirement plan as an asset or liability in its statement of financial position and to recognize changes in that funded status in comprehensive income in the year in which the changes occur. SFAS No. 158 also requires a business entity to measure the funded status of a plan as of the date of its year-end statement of financial position, with limited exceptions. An employer with publicly traded equity securities is required to initially recognize the funded status of a defined benefit postretirement plan and to provide the required disclosures as of the end of the fiscal year ending after December 15, 2006. As our defined benefit pension plans are currently overfunded and benefits are frozen, we recognized a corresponding asset on our balance sheet on December 31, 2006. As we do not consider this asset to be 40 material, the adoption of SFAS No. 158 did not have a material impact on our results of operations or our financial position. In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Liabilities — including an amendment of FASB Statement No. 115”. SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value. This statement will be effective for us January 1, 2008. We have not yet determined the impact, if any, that adopting this standard may have on our financial statements. SFAS No. 123R, “Share-Based Payment” (Revised 2004) Statement of Financial Accounting Standards No. 123 “Share-Based Payments” (“SFAS No. 123R”) was revised and promulgated in December 2004. We adopted this standard when required on January 1, 2006. On April 14, 2005, the SEC issued a release amending the compliance dates for SFAS No. 123R. Under the SEC’s new rule, companies in our position could implement SFAS No. 123R at the beginning of their next fiscal year, instead of the next reporting period as originally required under SFAS No. 123R, that begins after June 15, 2005. We originally intended to adopt SFAS No. 123R beginning on July 1, 2005 but based on the SEC’s action on April 14, 2005, we decided to adopt this standard effective on January 1, 2006. We adopted SFAS No. 123R under the modified prospective method of adoption. Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation” (“SFAS No. 123”), which became effective in 1996, allowed for the continued measurement of compensation cost for stock-based compensation using the intrinsic value based method under Accounting Principles Board Opinion No. 25 “Accounting for Stock Issued to Employees” (“APB No. 25”), provided that pro forma disclosures were made of net income or loss, assuming the fair value based method of SFAS No. 123 had been applied. We have elected to account for our stock-based compensation plans under APB No. 25 in 2004 and 2005. Upon adoption of SFAS No. 123R, we were required to recognize compensation expense using the fair value-based model for options that vest after the effective date of SFAS No. 123R adoption, including those that were granted prior to the effective date of SFAS No. 123R adoption. This resulted in us recording compensation expense for periods after the effective date of SFAS No. 123R adoption. Historically, under APB No. 25, we have recorded minimal amounts of stock-based compensation. On December 2, 2004, the Compensation Committee of our Board of Directors considered the significant impact that the use of fair values, rather than intrinsic values, would have on our future results of operations, as well as factors including that the management team had requested that their salaries be frozen for 2005, many non- management employees’ 2005 raises were to be below market levels, no management bonus payments were made for 2004 and the 2005 management incentive plan called for a performance in excess of our internal budget before any bonus payments were to be made, and approved the acceleration of vesting of outstanding but unvested stock options with an exercise price greater than $1.08. These options were not “in-the-money” at that time, and therefore, there was no compensation expense recorded in accordance with APB No. 25 as a result of this modification. However, for pro forma purposes, in accordance with SFAS No. 123, the remaining unamortized compensation related to these options, calculated under SFAS No. 123 of approximately $2.1 million, was recorded in 2004. This action effected options to purchase approximately 2.2 million shares, approximately 1.1 million of which were held by our Directors and Executive Officers. Had this action not been taken, and had all approximately 2.2 million options continued to vest according to the vesting schedules in place prior to the acceleration, we would have recorded compensation expense related to these options of approximately $870 thousand on a pro forma basis for the year ending December 31, 2005. On February 24, 2005, our Board of Directors considered the significant impact that the use of fair values, rather than intrinsic values, would have on our future results of operations, as well as factors including that the management team had requested that their salaries be frozen for 2005, many non-management employees’ 2005 raises were to be below market levels, no management bonus payouts were made for 2004 and the 2005 management incentive plan calls for a performance in excess of our internal budget before any bonus payments are made, and authorized our Stock Option Committee, which consisted solely of our Chief 41 Executive Officer, to immediately vest all options granted from that date through June 30, 2005 and to accelerate the vesting of any outstanding but unvested stock options with a strike price that is not “in-the-money” at its discretion (the aggregate authorization to the Stock Option Committee to be known as the “Vesting Authorization”) through June 30, 2005; for similar reasons and understanding the SEC had issued a release amending the compliance date for SFAS No. 123R, on May 9, 2005 our Board of Directors approved the extension of the Vesting Authorization to our Stock Option Committee from June 30, 2005 to December 31, 2005. On March 30, 2005 our Stock Option Committee exercised its discretion and accelerated the vesting of outstanding but unvested stock options with a strike price greater than or equal to $0.82. These options were not “in-the-money” at that time, and therefore, there was no compensation expense recorded in accordance with APB No. 25 as a result of this modification. However, for pro forma purposes, in accordance with SFAS No. 123, the remaining unamortized compensation related to these options, calculated under SFAS No. 123 of approximately $540 thousand, was recorded in 2005. This action effected approximately 750 thousand options, approximately 55 thousand of which were held by our Directors and Executive Officers. Had this action not been taken, and had all approximately 750 thousand options continued to vest according to the vesting schedules in place prior to the acceleration, we would have recorded incremental compensation related to these options of approximately $275 thousand on a pro forma basis for the nine months ending December 31, 2005. We also have an employee stock purchase plan under which we expect to recognize compensation expense under SFAS No. 123R beginning on January 1, 2006. There are four key inputs to the Black-Scholes model which we use to value our options: expected term, expected volatility, risk-free interest rate and expected dividends, all of which require us to make estimates. Our estimates for these inputs may not be indicative of actual future performance and changes to any of these inputs can have a material impact on the resulting fair value calculated for the option. Our expected term input was estimated in 2006 and 2005 based on our historical experience for time from option grant to option exercise for all employees and in 2004 based on a software program to which an input was our historical exercise experience for current employees; we treated all employees in one grouping in all three years. Our expected volatility input was estimated based on our historical stock price volatility in 2006 and 2005 and a combination of our historical price volatility and a peer group volatility in 2004. Our risk-free interest rate input was determined based on the U.S. Treasury yield curve at the time of option issuance in 2006, 2005 and 2004. Our expected dividends input was zero in 2006, 2005 and 2004. Different assumptions could materially impact the resulting option value calculated. In the twelve months ended December 31, 2006, we had stock option compensation of approximately $745 thousand related to recognition of the vesting of options to purchase approximately 1.1 million shares. The underlying assumptions made in valuing these stock options, weighted by number of options and stock fair value at the time of grant, were as follows: expected term of 2.89 years, expected volatility of 67%, risk-free interest rate of 4.65% and expected dividends of zero. A tranche of “at-the-money” options granted under these assumptions in the same number as above would require a fair value price of approximately $1.43 per share (the “Benchmark Tranche”) to yield the same value as above (the “Benchmark Value”). The following table represents the approximate decrease, in thousands of dollars, of the value of the Benchmark Tranche under different expected term and expected volatility assumptions assuming all other inputs are the same. For example, the Benchmark Tranche is “at-the-money” options to purchase approximately 1.1 million shares with a fair market stock value of $1.43 per share, and if the Benchmark Tranche is valued using an expected term of 2.89 years, expected volatility of 67%, a risk- free interest rate of 4.65% and expected dividends of zero, we obtain a fair value of approximately $745 thousand — the Benchmark Value. If we value the Benchmark Tranche under the same assumptions, except we assume an expected term of 5.0 years instead of 2.89 years and an expected volatility of 60% instead of 67%, we obtain a value of approximately $882 thousand, or an increase of approximately $137 thousand as compared to the Benchmark Value. 42 Time to Expiration (in years) 15% 612 30% 523 45% 431 60% 342 75% 255 90% 169 105% 87 120% 8 135% (67) 150% (139) Volatility 535 467 406 348 294 243 194 148 105 415 328 252 186 125 70 19 292 185 96 19 174 48 60 (48) (149) (243) (328) (404) (80) (198) (305) (401) (484) (555) (52) (188) (311) (418) (510) (586) (650) (137) (277) (400) (504) (589) (657) (711) (48) (208) (350) (470) (569) (647) (707) (751) (108) (271) (412) (528) (621) (691) (743) (779) (163) (326) (465) (576) (662) (724) (769) (798) (28) (211) (374) (510) (616) (695) (750) (788) (811) (71) (255) (418) (549) (650) (721) (770) (801) (820) 1 2 3 4 5 6 7 8 9 10 Stock option compensation related to recognition of the vesting of options of approximately $745 thousand for the year ended on December 31, 2006 may not be indicative of the future impact of SFAS No. 123R. Assuming all options vest according to the vesting schedules in place at December 31, 2006, we have approximately $62 thousand of compensation cost to be recognized after December 31, 2006, approximately $60 thousand of which is to be recognized in the year ending December 31, 2007. The Compensation Committee of our Board of Directors is currently considering alternatives regarding different forms of long-term compensation for future use, including the continued use of stock options. The decisions of the Compensation Committee of our Board of Directors regarding stock options is likely to be a key factor in the future impact of SFAS No. 123R on our financial statements. Item 7A. Quantitative and Qualitative Disclosures about Market Risk. Market risk represents the risk of loss that may impact the financial position, results of operations or cash flows due to adverse changes in financial and commodity market prices and rates. We are exposed to market risk in the areas of changes in United States and foreign interest rates and changes in foreign currency exchange rates as measured against the United States dollar. These exposures are directly related to our normal operating and funding activities. Interest Rate Risk The interest payable on certain of our lines of credit and other borrowings is variable based on the United States prime rate and, therefore, is effected by changes in market interest rates. At December 31, 2006, approximately $11.2 million was outstanding on these lines of credit and other borrowings with a weighted average interest rate of 10.68%. We also had approximately $5.3 million of cash and cash equivalents at December 31, 2006, the majority of which was invested in liquid interest bearing accounts. We had no interest rate hedge transactions in place on December 31, 2006. We completed an interest rate risk sensitivity analysis based on the above and an assumed one-percentage point increase/decrease in interest rates. If market rates increase/decrease by one percentage point, we would experience an increase/decrease in annual interest expense of approximately $59 thousand based on our outstanding balances as of December 31, 2006. 43 Foreign Currency Risk Our investment in foreign assets consists primarily of our investment in our European subsidiary. Foreign currency risk may impact our results of operations. In cases where we purchase inventory in one currency and sell corresponding products in another, our gross margin percentage is typically at risk based on foreign currency exchange rates. In addition, in cases where we may be generating operating income in foreign currencies, the magnitude of such operating income when translated into U.S. dollars will be at risk based on foreign currency exchange rates. Our agreements with suppliers and customers vary significantly in regard to the existence and extent of currency adjustment and other currency risk sharing provisions. We had no foreign currency hedge transactions in place on December 31, 2006. We have a wholly-owned subsidiary in Switzerland which uses the Swiss Franc as its functional currency. We purchase inventory in foreign currencies, primarily Japanese Yen and Euros, and sell corresponding products in U.S. dollars. We also sell products in foreign currencies, primarily Japanese Yen and Euros, where our inventory costs are in U.S. dollars. Based on our 2006 results of operations, if foreign currency exchange rates were to strengthen/weaken by 25% against the dollar, we would expect a resulting pre-tax loss/gain of approximately $878 thousand. 44 Item 8.

ORGANIZATION AND BUSINESS Heska Corporation (“Heska” or the “Company”) discovers, develops, manufactures, markets, sells, distributes and supports veterinary products. Heska’s core focus is on the canine and feline companion animal health markets. The Company has devoted substantial resources to the research and development of innovative products in these areas, where it strives to provide high value products for unmet needs and advance the state of veterinary medicine. Heska is comprised of two reportable segments, Core Companion Animal Health and Other Vaccines, Pharmaceuticals and Products. The Core Companion Animal Health segment includes diagnostic and other instruments and supplies as well as single use diagnostic and other tests, vaccines and pharmaceuticals, primarily for canine and feline use. These products are sold directly by the Company as well as through independent third party distributors and other distribution relationships. The Other Vaccines, Pharmaceuticals and Products segment (“OVP”), previously reported as the Diamond Animal Health segment, includes private label vaccine and pharmaceutical production, primarily for cattle but also for other animals including small mammals and fish. All OVP products are sold by third parties under third party labels. Cumulative net losses from inception of the Company in 1988 through December 31, 2006, have totaled $208.0 million. During the year ended December 31, 2006, the Company recorded a net income of approximately $1.8 million and operations provided cash of approximately $1.1 million. The Company’s ability to achieve sustained profitable operations will depend primarily upon its ability to successfully market its products and commercialize new products. There can be no guarantee that the Company will be successful in these endeavors or attain quarterly, annual, or sustained profitability in the future. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements include the accounts of the Company and of its wholly-owned subsidiaries since their respective dates of acquisitions. All material intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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. Significant estimates are required when establishing the allowance for doubtful accounts and the provision for excess/obsolete inventory, in determining the period over which the Company’s obligations are fulfilled under agreements to license product rights and/or technology rights, evaluating long-lived assets for impairment and in determining the need for, and the amount of, a valuation allowance on deferred tax assets. 52 Trade Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance based on historical write-off experience. The Company reviews its allowance for doubtful accounts monthly. Past due balances over 90 days and over a specified amount are reviewed individually for collectibility. Account balances are charged against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers. Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents and accounts receivable. The Company maintains the majority of its cash and cash equivalents with financial institutions that management believes are creditworthy in the form of demand deposits, U.S. government agency obligations and U.S. corporate commercial paper. The Company has no significant off-balance sheet concentrations of credit risk such as foreign exchange contracts, options contracts or other currency foreign hedging arrangements. Its accounts receivable balances are due primarily from domestic veterinary clinics and individual veterinarians, and both domestic and international corporations. Cash and Cash Equivalents Cash and cash equivalents are stated at cost, which approximates market, and include short-term, highly liquid investments with original maturities of less than three months. The Company valued its European Euro and Japanese Yen cash accounts at the spot market foreign exchange rate as of each balance sheet date, with changes due to foreign exchange fluctuations recorded in current earnings. The Company held 1,001,317 and 1,607,633 Euros at December 31, 2005 and 2006, respectively. The Company held 30,178,209 and 50,954,278 Yen at December 31, 2005 and 2006, respectively. The Company held 1,034,905 and 1,347,692 Swiss Francs at December 31, 2005 and 2006, respectively. The Company held 1,970 and 1,202 British Pounds at December 31, 2005 and 2006, respectively. Fair Value of Financial Instruments The Company’s financial instruments consist of cash and cash equivalents, short-term trade receivables and payables and notes payable, including the revolving line of credit. The carrying values of cash and cash equivalents and short-term trade receivables and payables approximate fair value. The fair value of notes payable is estimated based on current rates available for similar debt with similar maturities and collateral, and at December 31, 2005 and 2006, approximates the carrying value due primarily to the floating rate of interest on such debt instruments. Inventories Inventories are stated at the lower of cost or market using the first-in, first-out method. Inventory manufactured by the Company includes the cost of material, labor and overhead. If the cost of inventories exceeds estimated fair value, provisions are made to reduce the carrying value to estimated fair value. 53 Inventories, net consist of the following (in thousands): Raw materials Work in process Finished goods Allowance for excess or obsolete inventory Property and Equipment December 31, 2005 $ 3,002 3,090 6,318 (756) $ 11,654 2006 $ 5,337 3,426 5,851 (1,524) $ 13,090 Property and equipment are recorded at cost and depreciated on a straight-line basis over the estimated useful lives of the related assets. Leasehold improvements are amortized over the applicable lease period or their estimated useful lives, whichever is shorter. Maintenance and repairs are charged to expense when incurred, and major renewals and improvements are capitalized. Property and equipment consist of the following (in thousands): Land Building Machinery and equipment Leasehold and building improvements Less accumulated depreciation and amortization Estimated Useful Life N/A 10 to 20 years 3 to 15 years 7 to 15 years December 31, 2005 2006 377 2,678 20,427 4,931 28,413 (20,985) 7,428 $ $ 377 2,678 19,503 5,230 27,788 (20,840) 6,948 $ $ Depreciation and amortization expense for property and equipment was $1.3 million, $1.9 million and $1.7 million for the years ended December 31, 2004, 2005 and 2006, respectively. Realizability of Long-Lived Assets The Company continually evaluates whether events and circumstances have occurred that indicate the remaining estimated useful life of long-lived assets may warrant revision, or that the remaining balance of these assets may not be recoverable. When deemed necessary, the Company completes this evaluation by comparing the carrying amount of the assets against the estimated undiscounted future cash flows associated with them. If such evaluations indicate that the future undiscounted cash flows of amortizable long-lived assets are not sufficient to recover the carrying value of such assets, the assets are adjusted to their estimated fair values. Goodwill and Other Intangible Assets Goodwill is subject to an annual assessment for impairment. Impairment is indicated when the carrying amount of the related reporting unit is greater than its estimated fair value. The Company’s recorded goodwill relates to the 1997 acquisition of Heska AG, the Company’s Swiss operating subsidiary. This goodwill is reviewed at least annually for impairment. At December 31, 2005 and 2006, goodwill was approximately $714 thousand and $771 thousand, respectively, and is included in the assets of the Core Companion Animal Health segment. The Company completed its annual analysis of the fair value of its goodwill at December 31, 2006 and determined there was no indicated impairment of its goodwill. The change in carrying value of the goodwill between years was solely due to foreign currency rate 54 changes. There can be no assurance that future goodwill impairments will not occur. There are no other intangible assets that are not being amortized on a periodic basis. The Company incurred costs, paid to third-party law firms, to prosecute patents on its proprietary technologies. The Company capitalized qualifying costs related to its patents. At December 31, 2005, the cost basis of the capitalized patent costs was approximately $2.3 million, the accumulated amortization was approximately $748 thousand, and the net book value was approximately $1.5 million. These costs were amortized over an average life of 15 years which was the estimated life of the patents. Related amortization expense for the years ended December 31, 2004, 2005 and 2006, was approximately $393 thousand, $157 thousand and $334 thousand, respectively. In December 2006, the Company sold the patents underlying these capitalized patent costs for a gain of approximately $155 thousand over the then book value affiliated with the sale of these patents, which included these capitalized patent costs. Accordingly, the Company had no capitalized patent costs at December 31, 2006. Derivative Instruments and Hedging Activities The Company has utilized derivative financial instruments to reduce financial market risks in the past. If used, these instruments may be used to hedge foreign currency, interest rate and certain equity market exposures of underlying assets, liabilities and other obligations. The Company does not use derivative financial instruments for speculative or trading purposes. The Company had no hedging activities in 2004, 2005 and 2006. Revenue Recognition The Company generates its revenues through sale of products and services, licensing of product and technology rights, and research and development services. Revenue is accounted for in accordance with the guidelines provided by SEC Codification of Staff Accounting Bulletins, Topic 13: Revenue Recognition. The Company’s policy is to recognize revenue when the applicable revenue recognition criteria have been met, which generally include the following: · Persuasive evidence of an arrangement exists; · Delivery has occurred or services rendered; · Price is fixed or determinable; and · Collectibility is reasonably assured. Revenue from the sale of products is generally recognized after both the goods are shipped to the customer and acceptance has been received, if required, with an appropriate provision for estimated returns and other allowances. The terms of the customer arrangements generally pass title and risk of ownership to the customer at the time of shipment. Certain customer arrangements provide for acceptance provisions. Revenue for these arrangements is not recognized until the acceptance has been received or the acceptance period has lapsed. The Company maintains an allowance for sales returns based upon its customer policies and historical experience. Shipping and handling costs charged to customers is included as revenue, and the related costs are recorded as a component of cost of products sold. In addition to its direct sales force, the Company utilizes independent third-party distributors to sell its products. Distributors purchase goods from the Company, take title to those goods and resell them to their customers in the distributors’ territory. Upfront payments received by the Company under arrangements for product, patent or technology rights in which the Company retains an interest in the underlying product, patent or technology are initially deferred, and revenue is subsequently recognized over the estimated life of the agreement, product, patent or technology. The Company received approximately $3.2 million, $560 thousand and $295 thousand of such 55 payments in 2004, 2005 and 2006, respectively. Revenue from royalties is recognized based upon historical experience or as the Company is informed of sales to which it is entitled to royalties. For multiple-element arrangements that are not subject to a higher level of authoritative literature, the Company follows the guidelines of the Financial Accounting Standards Board’s (“FASB”) Emerging Issues Task Force (“EITF”) Issue No. 00-21, “Accounting for Revenue Arrangements with Multiple Deliverables” (“EITF 00-21”), in determining the separate units of accounting. For those arrangements subject to the separation criteria of EITF 00- 21, the Company accounts for each of the individual units of accounting as a separate and discrete earnings process considering, among other things, whether a delivered item has value to the client on a standalone basis. For such multiple-element arrangements, total revenue is allocated to the separate units of accounting based upon objective and reliable evidence of the fair value of the undelivered item. The determination of separate units of accounting, and the determination of objective and reliable evidence of fair value of the undelivered item, both require judgments to be made by the Company. Cost of Products Sold Royalties payable in connection with certain licensing agreements (see Note 9) are reflected in cost of products sold as incurred. Stock-Based Compensation During the years ended December 31, 2004 and 2005, the Company accounted for its stock-based compensation plans using the intrinsic value method in accordance with Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB No. 25”), and related interpretations, and follows the disclosure provisions of Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation” (“SFAS No. 123”) and Statement of Financial Accounting Standards No. 148, “Accounting for Stock-Based Compensation — Transition and Disclosure” (“SFAS No. 148”). Effective January 1, 2006, the Company adopted Statement of Financial Accounting Standards No. 123 (revised 2004) “Share-Based Payment” (“SFAS No. 123R”). Any accounting difference between SFAS No. 123R and SFAS No. 123, as historically applied by the Company, shall be defined as the “123R Effect”. During the year ended December 31, 2006, the 123R Effect reduced the Company’s income from continuing operations, income before income taxes and net income by $782 thousand, basic and diluted earnings per share by $0.02 and $0.01 per share, respectively, and did not have a material impact on cash flow from operations and cash flow from financing. At December 31, 2006, the Company had two stock-based compensation plans. See Note 6 for a description of these plans and additional disclosures regarding the plans. The Company recorded compensation expense of $91 thousand and $67 thousand for the years ended December 31, 2004 and 2005, respectively, related to grants of restricted common stock. The Company recognized $23 thousand of compensation expense related to the exercise of one option in 2005. For the year ended December 31, 2006, the Company recorded compensation expense of approximately $782 thousand related to its stock-based compensation plans. Had compensation expense for the Company’s stock-based compensation plans been based on the fair value at the grant dates for awards under those plans, consistent with the methodology of SFAS No. 123, the Company’s net loss and net loss per share for the years ended December 31, 2004 and 2005 would approximate the pro forma amounts as follows (in thousands, except per share amounts): 56 Net income (loss) as reported Stock-based employee compensation expense included in the determination of net loss, as reported Stock-based employee compensation expense as if the fair value based method had been applied to all awards Net income (loss), pro forma Net income (loss) per share: Basic and diluted — as reported Basic and diluted — pro forma Year Ended December 31, 2004 2005 (in thousands except per share data) (4,815) 91 (4,129) (8,853) (0.10) (0.18) $ $ $ $ 282 90 (3,175) (2,803) 0.01 (0.06) $ $ $ $ As discussed in more detail in Note 6, in December 2004 and March 2005 the vesting of options to purchase approximately 2.2 million shares and 750 thousand shares, respectively, was accelerated. These options were not “in-the-money” at the time of acceleration and, therefore, there was no compensation expense recorded in accordance with APB No. 25 as a result of the modifications. However, for pro forma purposes in accordance with SFAS No. 123, the remaining unamortized compensation related to these options, calculated under SFAS No. 123 of approximately $2.1 million and $540 thousand was recorded in 2004 and 2005, respectively, and included in the table above. Advertising Costs The Company expenses advertising costs as incurred. Advertising expenses were $712 thousand, $353 thousand and $443 thousand for the years ended December 31, 2004, 2005 and 2006, respectively. Income Taxes The Company records a current provision for income taxes based on estimated amounts payable or refundable on tax returns filed or to be filed each year. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates, in each tax jurisdiction, expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. The overall change in deferred tax assets and liabilities for the period measures the deferred tax expense or benefit for the period. Deferred tax assets are reduced by a valuation allowance based on judgmental assessment of available evidence if the Company is unable to conclude that it is more likely than not that some or all of the deferred tax assets will be realized. Basic and Diluted Net Income (Loss) Per Share Basic net loss per common share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed using the sum of the weighted average number of shares of common stock outstanding, and, if not anti-dilutive, the effect of outstanding common stock equivalents (such as stock options and warrants) determined using the treasury stock method. In 2004, due to the Company’s net loss, all potentially dilutive securities are anti-dilutive and as a result, basic net loss per share is the same as diluted net loss per share for all periods prior to 2005. At December 31, 2005 and 2006, securities that have been excluded from diluted net income (loss) per share because they would be anti-dilutive are outstanding options to purchase 7,918,601 and 3,721,800 shares, respectively, of the Company’s 57 common stock. Securities included in the diluted net income per share calculation at December 31, 2005 and 2006, using the treasury stock method, were outstanding options to purchase approximately 788 thousand and 2.6 million shares of the Company’s common stock, respectively. Comprehensive Income (Loss) Comprehensive income (loss), as shown in the Consolidated Statement of Stockholders’ Equity, includes net income (loss) adjusted for the results of certain stockholders’ equity changes. Such changes include foreign currency items and minimum pension liability adjustments. At December 31, 2006, Accumulated Other Comprehensive Income consists of $159 thousand gain for cumulative translation adjustments, $89 thousand for unrealized pension liability and $22 thousand of unrealized gain on available for sale investments. At December 31, 2005, Accumulated Other Comprehensive Income consists of $74 thousand loss for cumulative translation loss adjustments and $27 thousand of unrealized gain on available for sale securities. At December 31, 2004, Accumulated Other Comprehensive Loss consists of cumulative translation loss adjustments of $311 thousand and income from minimum pension liability adjustments and other of $141 thousand. Foreign Currency Translation The functional currency of the Company’s Swiss subsidiary is the Swiss Franc. Assets and liabilities of the Company’s Swiss subsidiary are translated using the exchange rate in effect at the balance sheet date. Revenue and expense accounts and cash flows are translated using an average of exchange rates in effect during the period. Cumulative translation gains and losses are shown in the consolidated balance sheets as a separate component of stockholders’ equity. Exchange gains and losses arising from transactions denominated in foreign currencies (i.e., transaction gains and losses) are recognized as a component of other income (expense) in current operations, as are exchange gains and losses on intercompany transactions expected to be settled in the near term. New Accounting Pronouncements In February 2006, the FASB issued SFAS No. 155, “Accounting for Certain Hybrid Financial Instruments -an amendment of FASB Statements No. 133 and 140,” which simplifies accounting for certain hybrid financial instruments by permitting fair value remeasurement for any hybrid instrument that contains an embedded derivative that otherwise would require bifurcation and eliminates a restriction on the passive derivative instruments that a qualifying special-purpose entity may hold. SFAS No. 155 is effective for all financial instruments acquired, issued or subject to a remeasurement (new basis) event occurring after the beginning of an entity’s first fiscal year that begins after September 15, 2006. The adoption of SFAS No. 155 will have no impact on the Company’s results of operations or the Company’s financial position. In March 2006, the FASB issued SFAS No. 156, “Accounting for Servicing of Financial Assets - an amendment of FASB Statement No. 140,” which establishes, among other things, the accounting for all separately recognized servicing assets and servicing liabilities by requiring that all separately recognized servicing assets and servicing liabilities be initially measured at fair value, if practicable. SFAS No. 156 is effective as of the beginning of an entity’s first fiscal year that begins after September 15, 2006. The adoption of SFAS No. 156 will have no impact on the Company’s results of operations or financial position. In June 2006, the FASB issued FASB Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109,” which establishes that the financial statement effects of a tax position taken or expected to be taken in a tax return are to be recognized in the financial statements when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. FIN 48 is effective for fiscal years beginning after December 15, 2006. The 58 adoption of FIN 48 is not expected to have a material impact on the Company’s results of operations or financial position. In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements,” which establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. SFAS No. 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The adoption of SFAS No. 157 is not expected to have a material impact on the Company’s results of operations or financial position. In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans - an amendment of FASB Statements No. 87, 88, 106, and 132(R),” which requires a business entity to recognize the overfunded or underfunded status of a single- employer defined benefit postretirement plan as an asset or liability in its statement of financial position and to recognize changes in that funded status in comprehensive income in the year in which the changes occur. SFAS No. 158 also requires a business entity to measure the funded status of a plan as of the date of its year-end statement of financial position, with limited exceptions. An employer with publicly traded equity securities is required to initially recognize the funded status of a defined benefit postretirement plan and to provide the required disclosures as of the end of the fiscal year ending after December 15, 2006. The Company’s defined benefit pension plan is currently overfunded and benefits are frozen. The adoption of SFAS No. 158 has been reflected in the Company’s results of operations and financial position. In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Liabilities — including an amendment of FASB Statement No. 115”. SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value. This statement will be effective for us January 1, 2008. The Company has not yet determined the impact, if any, that adopting this standard may have on its financial statements. The Company adopted SFAS No. 123R effective January 1, 2006 under the modified prospective method of adoption. This pronouncement requires companies to measure the cost of employee services received in exchange for an award of equity instruments (including stock options) based on the grant- date fair value of the award. The fair value is estimated using option pricing models where applicable. The resulting cost is recognized over the period during which an employee is required to provide service in exchange for the award, usually the vesting period. This represents a change in accounting for the Company’s stock option plans and employee stock purchase plan. Prior to the Company’s adoption of SFAS No. 123R on January 1, 2006, the Company measured stock-based compensation under the intrinsic value based method of APB No. 25 with pro forma disclosures of net income or loss assuming the fair value method of SFAS No. 123, which became effective in 1996, had been applied. 3. CAPITAL LEASE OBLIGATIONS The Company has entered into certain capital lease agreements for laboratory equipment, office equipment, machinery and equipment, and computer equipment and software. At December 31, 2005 and 2006, the Company had capitalized machinery and equipment under capital leases with a gross value of approximately $38 thousand and $38 thousand, respectively, and net book value of approximately $25 thousand and $17 thousand, respectively. The capitalized cost of the equipment under capital leases is included in the accompanying consolidated balance sheets under the respective asset classes. Under the terms of the Company’s lease agreements, the Company is required to make monthly payments of principal and interest through the year 2009, at interest rates ranging from 11.0% to 14.0% per annum. The equipment under the capital leases serves as security for the leases. 59 The future annual minimum required payments under capital lease obligations as of December 31, 2006 were as follows (in thousands): Year Ending December 31, 2007 2008 2009 2010 Total future minimum lease payments Less amount representing interest Present value of future minimum lease payments Less current portion Total long-term capital lease obligations 4. LONG-TERM DEBT Long-term debt consists of the following (dollars in thousands): $ 10 10 2 — 22 3 19 8 $ 11 Promissory note to the City of Des Moines was paid in full in June 2006. Real estate mortgage loan with a commercial bank, due in monthly installments, with the balance due of $163 thousand in full June 30, 2009, with a stated interest rate of prime plus 2.75% at December 31, 2005 and prime plus 2.5% at December 31, 2006 (10.0% and 10.75%, respectively). Term loan with a commercial bank, secured by machinery and equipment, due in monthly installments beginning February 2006 with the balance due of $481 thousand in full June 30, 2009, with a stated interest rate of prime plus 2.75% at December 31, 2005 and prime plus 2.5% at December 31, 2006 (10.0% and 10.75%, respectively). Term loan with a commercial bank, secured by machinery and equipment, due in monthly installments beginning February 2006 with the balance due of $120 thousand in full June 30, 2009, with a stated interest rate of prime plus 2.75% at December 31, 2005 and prime plus 2.5% at December 31, 2006 (10.0% and 10.75%, respectively). Subordinated promissory note with a significant customer for facilities improvements in Des Moines, secured by the manufacturing facility, due in May 2007, with a stated interest rate of prime plus 1.0% at December 31, 2005 and December 31, 2006 (8.25% and 9.25%, respectively).

The agreement includes the real estate mortgage loan and term loans above, and a $12.0 million asset-based revolving line of credit with a stated interest rate at December 31, 2006 of prime plus 2.5%. Amounts due under the credit facility are secured by a first security interest in essentially all of the Company’s assets. Under the agreement, the Company is required to comply with certain financial and non-financial covenants. Among the financial covenants are requirements for monthly minimum book net 60 worth, quarterly minimum net income and monthly minimum liquidity. The amount available for borrowings under the line of credit varies based upon available cash, eligible accounts receivable and eligible inventory. As of December 31, 2006, approximately $8.0 million was outstanding on the line of credit and there was $4.0 million available capacity for additional borrowings under the line of credit agreement. Maturities of long-term debt as of December 31, 2006 were as follows (in thousands): Year Ending December 31, 2007 2008 2009 2010 $ 1,267 767 1,149 — $ 3,183 5. INCOME TAXES As of December 31, 2006, the Company had a net domestic operating loss carryforward ("NOL"), of approximately $167.8 million, a domestic alternative minimum tax credit of approximately $81 thousand and a domestic research and development tax credit carryforward of approximately $307 thousand. The NOL and tax credit carryforwards are subject to alternative minimum tax limitations and to examination by the tax authorities. In addition, the Company had a "change of ownership" as defined under the provisions of Section 382 of the Internal Revenue Code of 1986, as amended (an "Ownership Change"). The Company believes the latest, and most restrictive, Ownership Change occurred at the time of its initial public offering in July 1997. The Company does not believe this Ownership Change will place a significant restriction on its ability to utilize its NOL in the future. The Company also had an NOL of approximately $1.9 million in Switzerland at December 31, 2006 related to losses previously recorded by Heska AG, the Company's operating subsidiary in Switzerland. Based on the profitable operating performance of Heska AG, the Company's evaluation determined that its NOL in Switzerland was realizable on a more-likely-than-not basis and the related valuation allowance was released in the fourth quarter of 2005, resulting in an income tax benefit of approximately $185 thousand and a corresponding net deferred tax asset of approximately $185 thousand on December 31, 2005. The Company subsequently obtained agreements from the tax authorities in the canton of Fribourg (the "Tax Agreements") regarding the Company's determination of taxable income. The Company anticipates the Tax Agreements will reduce the Company's taxable income and therefore tax obligation in Switzerland in future years as compared to prior expectations. In addition, the Tax Agreements reduced the Company's taxable income in Switzerland in 2005 and 2006 from previous estimates for financial reporting purposes. Accordingly, due to the Company's lower income expectations in Switzerland related to the Tax Agreements, the Company no longer believes it will be able to utilize all of its NOL in Switzerland before it fully expires and has made an associated reduction in its net deferred tax asset via an increase in the related valuation allowance along with a corresponding income tax expense journal entry in the fourth quarter of 2006. At December 31, 2006 the Company had total deferred tax assets of approximately $49 thousand. As a result of the Tax Agreements, the Company has a smaller net deferred tax asset, lower foreign taxable income and greater domestic taxable income than the Company estimated when it reported its results for the year ended December 31, 2005. Heska AG has a "tax holiday" from canton, municipal and church income taxes in the canton of Fribourg through August 31, 2007. These tax holidays reduce the amount of deferred tax asset that would otherwise be recorded by approximately $14 thousand. The Company does not have a "tax holiday" for federal taxes in Switzerland. The Company also recognized approximately $58 thousand of income tax expense for the year ended December 31, 2006 related to alternative minimum income tax obligations in the United States. The Company's domestic NOL represents a deferred tax asset, which has been completely offset by a valuation allowance. Based on the Company's domestic cumulative operating losses in recent years, as well as other factors including uncertainties regarding the Company's future operations, the Company has been unable to conclude that it was more likely than not on December 31, 2006 that the Company will realize a future benefit from its domestic NOL. Accordingly, a valuation allowance has been established for the entire domestic deferred tax asset and no benefit for domestic income taxes has been recognized in the accompanying consolidated statements of operations. 61 The components of income (loss) before income taxes were as follows (in thousands): Domestic Foreign Temporary differences that give rise to the components of deferred tax assets are as follows (in thousands): Current deferred tax assets (liabilities): Inventory Accrued compensation Net operating loss carryforwards—foreign Other Valuation allowance Total current deferred tax assets (liabilities) Noncurrent deferred tax assets (liabilities): Research and development and other credits Deferred revenue Amortization of intangible assets Property and equipment Net operating loss carryforwards—domestic Net operating loss carryforwards—foreign Valuation allowance Total noncurrent deferred tax assets (liabilities) The components of the income tax expense (benefit) are as follows (in thousands): Current income tax expense (benefit): Federal State Foreign Year Ended December 31, 2005 2004 2006 $ (5,718) 903 $ (4,815) $ (1,080) 1,177 97 $ $ $ 1,976 58 2,034 December 31, 2005 2006 $ $ $ $ 309 17 75 317 718 (643) 75 330 4,853 (584) 945 65,635 110 71,289 (71,179) 110 $ $ $ $ 555 52 17 347 971 (954) 17 388 4,217 — 925 64,345 32 69,907 (69,875) 32 Year Ended December 31, 2005 2006 2004 $ $ — — — $ — — — 58 — — Total current expense (benefit) Deferred income tax expense (benefit): Federal State Foreign Total deferred benefit Valuation allowance Total income tax expense (benefit) 62 — — (1,790) (231) — (2,021) 2,021 — $ $ — — (185) (185) — (185) $ 58 — — 148 148 — 206 The Company’s income tax benefit relating to losses, respectively, for the periods presented differ from the amounts that would result from applying the federal statutory rate to those losses as follows: Statutory federal tax rate State income taxes, net of federal benefit Other permanent differences Foreign NOL utilization Foreign rate difference Current year impact of foreign tax holiday Loss of foreign NOL benefit under new tax rate agreement Swiss NOL carryforward Change in valuation allowance Other Effective income tax rate 6.

In 1997, the board of directors adopted the 1997 Stock Incentive Plan and terminated two prior option plans. However, options granted and unexercised under the prior plans are still outstanding. All shares that remained available for grant under the terminated plans were incorporated into the 1997 Plan. In addition, all shares subsequently cancelled under the prior plans are added back to the 1997 Plan on a quarterly basis as additional options available to grant. In May 2003, the stockholders approved a new plan, the 2003 Stock Incentive Plan, which allows for the granting of options for up to 2,390,500 shares of the Company’s common stock. The number of shares reserved for issuance under all plans as of January 1, 2007 was 4,910,988. The stock options granted by the board of directors may be either incentive stock options (“ISOs”) or non-qualified stock options (“NQs”). The exercise price for options under all of the plans may be no less than 100% of the fair value of the underlying common stock for ISOs or 85% of fair value for NQs. Options granted will expire no later than the tenth anniversary subsequent to the date of grant or three months following termination of employment, except in cases of death or disability, in which case the options will remain exercisable for up to twelve months. Under the terms of the 1997 Plan, in the event the Company is sold or merged, outstanding options will either be assumed by the surviving corporation or vest immediately. There are four key inputs to the Black-Scholes model which the Company uses to estimate fair value for options which it issues: expected term, expected volatility, risk-free interest rate and expected dividends, all of which require the Company to make estimates. The Company’s estimates for these inputs may not be indicative of actual future performance and changes to any of these inputs can have a material impact on the resulting estimated fair value calculated for the option. The Company’s expected term input was estimated based on the Company’s historical experience for time from option grant to option exercise for all employees in 2006 and 2005 and based on a software program to which an input was the Company’s historical exercise experience for current employees in 2004; the Company treated all employees in one grouping in all three years. The Company’s expected volatility input was estimated based on the Company’s historical stock price volatility in 2006 and 2005 and a combination of the Company’s historical stock price volatility and a peer group volatility in 2004. The Company’s risk-free interest rate input was determined based on the U.S. Treasury yield curve at the time of option issuance in 2006, 2005 and 2004. The Company’s expected 63 dividends input was zero in 2006, 2005 and 2004. Weighted average assumptions used in 2006, 2005 and 2004 for each of these four key inputs are listed in the following table. Risk-free interest rate Expected lives Expected volatility 2004 2005 2006 3.62% 4.17% 4.81% 4.5 years 2.8 years 2.8 years 76% 86% 65% Expected dividend yield 0% 0% 0% A summary of the Company’s stock option plans is as follows: Outstanding at beginning of period Granted at Market Granted above Market Cancelled Exercised Outstanding at end of period Exercisable at end of period 2004 Year Ended December 31, 2005 2006 Weighted Average Exercise Price $ 1.5163 $ 1.8890 $ 2.6300 $ 3.8742 $ 0.7476 $ 1.4509 $ 1.5532 Options 7,954,648 2,575,830 418 (792,963) (386,974) 9,350,959 7,939,567 Weighted Average Exercise Price $ 1.4509 $ 1.0130 $ — $ 1.6345 $ 0.7222 $ 1.3251 $ 1.3373 Options 9,350,959 3,999,897 — (821,161) (540,113) 11,989,582 11,765,335 Weighted Average Exercise Price $ 1.3251 $ 1.5175 $ — $ 1.3042 $ 1.0418 $ 1.3575 $ 1.3585 Options 11,989,582 1,078,891 — (681,377) (568,273) 11,818,823 11,792,445 The total estimated fair value of stock options granted during the years ended December 31, 2006, 2005 and 2004 were computed to be approximately $718 thousand, $2.2 million and $3.0 million, respectively. The amounts are amortized ratably over the vesting periods of the options. The weighted average estimated fair value of options granted during the years ended December 31, 2006, 2005 and 2004 was computed to be approximately $0.68, $0.56 and $1.16, respectively. The total intrinsic value of options exercised during the years ended December 31, 2006, 2005 and 2004 were $251 thousand, $123 thousand and $483 thousand, respectively. The cash proceeds from options exercised during the years ended December 31, 2006, 2005 and 2004 were $592 thousand, $390 thousand and $289 thousand. The Company does not consider the tax benefit realized as a result of the exercise of these options to be material given the Company’s relatively large NOL in the United States. The following table summarizes information about stock options outstanding and exercisable at December 31, 2006. Exercise Prices $0.34 — $0.87 $0.88 — $1.05 $1.06 — $1.24 $1.25 — $1.68 $1.69 — $13.75 $0.34 — $13.75 Number of Options Outstanding at December 31, 2006 1,994,613 2,364,021 1,964,429 2,937,738 2,558,022 11,818,823 Options Outstanding Options Exercisable Weighted Average Remaining Contractual Life in Years Weighted Average Exercise Price 6.15 7.71 5.71 7.95 6.50 6.91 $ $ $ $ $ $ 0.6457 0.9008 1.1220 1.3822 2.4869 1.3575 Number of Options Exercisable at December 31, 2006 1,982,402 2,364,021 1,950,262 2,937,738 2,558,022 11,792,445 Weighted Average Exercise Price 0.6454 0.9008 1.1222 1.3822 2.4869 1.3585 $ $ $ $ $ $ As of December 31, 2006, there was $62 thousand of total unrecognized compensation expense related to outstanding stock options. That cost is expected to be recognized over a weighted-average period of 0.4 years with all cost to be recognized by the end of May 2008, assuming all options vest according to the 64 vesting schedules in place at December 31, 2006. As of December 31, 2006, the aggregate intrinsic value of outstanding options was approximately $5.9 million and the aggregate intrinsic value of exercisable options was approximately $5.9 million. Modifications to and Vesting of Certain Stock Option Grants On December 2, 2004 the Compensation Committee of the Company’s Board of Directors (the “Compensation Committee”) considered the significant impact that the use of fair values, rather than intrinsic values, would have on the Company’s future results of operations, as well as factors including that the management team had requested that their salaries be frozen for 2005, many non-management employees’ 2005 raises were to be below market levels, no management bonus payments were made for 2004 and the 2005 management incentive plan called for a performance in excess of the Company’s internal budget before any bonus payments were to be made, and approved the acceleration of vesting of outstanding but unvested stock options with an exercise price greater than $1.08. These options were not “in-the-money” at that time, and therefore, there was no compensation expense recorded in accordance with APB No. 25 as a result of this modification. However, for pro forma purposes, in accordance with SFAS No. 123, the remaining unamortized compensation related to these options, calculated under SFAS No. 123 of approximately $2.1 million, was recorded in 2004. This action effected options to purchase approximately 2.2 million shares, approximately 1.1 million of which were held by the Company’s Directors and Executive Officers. Had this action not been taken, and had all approximately 2.2 million options continued to vest according to the vesting schedules in place prior to the acceleration, compensation expense related to these options of $870 thousand would have been recorded on a pro forma basis during the year ended December 31, 2005, with the remainder, approximately $1.2 million, recorded as compensation expense after the adoption of SFAS 123R when required on January 1, 2006. On February 24, 2005, the Company’s Board of Directors (the “Board of Directors”) considered the significant impact that the use of fair values, rather than intrinsic values, would have on the Company’s future results of operations, as well as factors including that the management team had requested that their salaries be frozen for 2005, many non-management employees’ 2005 raises were to be below market levels, no management bonus payments were made for 2004 and the 2005 management incentive plan called for a performance in excess of the Company’s internal budget before any bonus payments were to be made, and authorized the Company’s Stock Option Committee (the “Stock Option Committee”), which consisted solely of the Company’s Chief Executive Officer, to immediately vest all options granted from that date through June 30, 2005 and to accelerate the vesting of any outstanding but unvested stock options with a strike price that is not “in-the-money” at its discretion (the aggregate authorization to the Stock Option Committee to be known as the “Vesting Authorization”) through June 30, 2005; for similar reasons and understanding the SEC had issued a release amending the compliance date for SFAS No. 123R, on May 9, 2005, the Board of Directors approved the extension of the Vesting Authorization to the Stock Option Committee from June 30, 2005 to December 31, 2005. On March 30, 2005, the Stock Option Committee exercised its discretion and accelerated the vesting of outstanding but unvested stock options with a strike price greater than or equal to $0.82. These options were not “in-the-money” at that time, and therefore, there was no compensation expense recorded in accordance with APB No. 25 as a result of this modification. However, for pro forma purposes, in accordance with SFAS No. 123, the remaining unamortized compensation related to these options, calculated under SFAS No. 123 of approximately $540 thousand, was recorded in 2005. This action effected options to purchase approximately 750 thousand shares, approximately 55 thousand of which were held by the Company’s Directors and Executive Officers. Had this action not been taken and had all approximately 750 thousand options continued to vest according to the vesting schedules in place prior to the acceleration, compensation expense related to these options of $275 thousand would have been recorded on a pro forma basis during the nine months ended December 31, 2005, with the remainder, approximately $265 thousand, recorded as compensation expense after the adoption of SFAS 123R when required on January 1, 2006. All options granted in 2005 on or after March 30, 2005, which totaled options to purchase approximately 3.9 million shares, were granted with immediate vesting. 65 Employee Stock Purchase Plan (the “ESPP”) Under the 1997 Employee Stock Purchase Plan, the Company is authorized to issue up to 2,750,000 shares of common stock to its employees, of which 2,197,548 had been issued as of December 31, 2006. Employees of the Company and its U.S. subsidiaries who are expected to work at least 20 hours per week and five months per year are eligible to participate. Under the terms of the plan, employees can choose to have up to 10% of their annual base earnings withheld to purchase the Company’s common stock. Each enrollment period is one year, with six-month measurement periods ending June 30 and December 31. The purchase price of the stock for June 30 and December 31 was 85% of the end-of-measurement-period market price. For the years ended December 31, 2004, 2005 and 2006, the weighted-average fair value of the purchase rights granted was $0.44, $0.27 and $0.36 per share, respectively. Pro forma stock-based compensation was approximately $58 thousand and $65 thousand in 2004 and 2005, respectively, for the ESPP. Beginning in 2006, stock-based compensation was expensed. Restricted Stock Exchange On August 9, 2001, the Board of Directors approved a proposal to give Colorado-based Heska employees an opportunity to exchange all options outstanding with exercise prices greater than $3.90 per share under the 1997 Stock Incentive Plan for shares of restricted stock. The offer closed on September 28, 2001 with options to purchase 1,044,900 shares of common stock exchanged for 1,044,900 shares of restricted stock. The fair value of the restricted stock at the time of the exchange was $0.68 per share. The restricted stock vested over 48 months beginning November 1, 2001. This exchange resulted in deferred compensation of approximately $710 thousand that was recognized over the vesting period of the restricted stock. The Company recognized $91 thousand and $67 thousand of non-cash compensation expense from this exchange in 2004 and 2005, respectively. A total of approximately 728 thousand shares vested under the exchange offer. The final vesting date was October 1, 2005 and employees may sell previously vested shares. 7. MAJOR CUSTOMERS The Company had no customers in 2004, 2005 and 2006 who represented 10% or more of total revenue. At December 31, 2006, the Company had one customer, Schering-Plough Animal Health Corporation (“SPAH”), who represented 13% of total accounts receivable. No customer represented 10% or more of total accounts receivable at December 31, 2005. 8. SUPPLEMENTAL DISCLOSURE OF CASH FLOW INFORMATION Cash paid for interest Purchase of assets under capital lease financing 9. COMMITMENTS AND CONTINGENCIES $ $ 2004 Year Ended December 31, 2005 (in thousands) $ $ 1,004 — $ $ 690 24 2006 1,178 — The Company holds certain rights to market and manufacture all products developed or created under certain research, development and licensing agreements with various entities. In connection with such agreements, the Company has agreed to pay the entities royalties on net product sales. In the years ended December 31, 2004, 2005 and 2006, royalties of $1.0 million, $895 thousand and $722 thousand became payable under these agreements, respectively. The Company has contracts with two suppliers for unconditional annual minimum inventory purchases totaling approximately $3.5 million in fiscal 2007 and $2.4 million through 2010. 66 The Company has entered into operating leases for its office and research facilities and certain equipment with future minimum payments as of December 31, 2006 as follows (in thousands): Year Ending December 31, 2007 2008 2009 2010 2011 Thereafter $ 1,533 1,584 1,622 1,661 1,702 22,101 $ 30,203 The Company had rent expense of $774 thousand, $1.4 million and $1.8 million in 2004, 2005 and 2006, respectively. From time to time, the Company may be involved in litigation relating to claims arising out of its operations. For example, on September 9, 2005, United Vaccines, Inc. (“United”), a customer of our OVP segment, filed a lawsuit in Madison, Wisconsin against our Diamond Animal Health, Inc. subsidiary (“Diamond”) and Heska Corporation alleging various claims, including breach of contract and breach of warranty, and demanding compensatory and punitive damages. On October 20, 2005, we filed counterclaims on behalf of Diamond as well as a motion to dismiss all claims against Heska Corporation. United filed an amended complaint on November 16, 2005 and Diamond filed an amended counterclaim on January 25, 2006. The matter proceeded to a jury trial. On October 18, 2006, all remaining claims against Diamond and Heska Corporation were dismissed and United was found in breach of contract with corresponding damages owed to Diamond. In the course of the litigation, we discovered that United had dissolved as of December 29, 2005. We also came to believe that United had transferred substantially all its assets to an Indiana Domestic Limited Liability Company (“LLC”). On December 28, 2006, United filed a Notice of Appeal with the Seventh Circuit Court of Appeals. The parties to this matter ultimately signed a settlement and release agreement, as outlined in Note 12. As of December 31, 2006, the Company was not party to any legal proceedings other than the above that are expected, individually or in the aggregate, to have a material effect on its business, financial condition or operating results. The Company generally warrants that its products and services will conform to published specifications. The typical warranty period is one year from delivery of the product or service. The typical remedy for breach of warranty is to correct or replace any defective product, and if not possible or practical, the Company will accept the return of the defective product and refund the amount paid. Historically, the Company has incurred minimal warranty costs, and as a result, does not maintain a warranty reserve. The Company’s licensing arrangements generally include a product indemnification provision that will indemnify and defend a licensee in actions brought against the licensee that claim the Company’s patents infringe upon a copyright, trade secret or valid patent. Historically, the Company has not incurred any significant costs related to product indemnification claims, and as a result, does not maintain a reserve for such exposure. 10. SEGMENT REPORTING The Company is comprised of two reportable segments, Core Companion Animal Health (“CCA”) and Other Vaccines, Pharmaceuticals and Products (“OVP”). The Core Companion Animal Health segment includes diagnostic and monitoring instruments and supplies, as well as single use diagnostic and other tests, vaccines and pharmaceuticals, primarily for canine and feline use. These products are sold directly by the Company as well as through independent third-party distributors and other distribution relationships. CCA segment products manufactured at the Des Moines, Iowa production facility included in the OVP segment’s 67 assets are transferred at cost and are not recorded as revenue for the OVP segment. The Other Vaccines, Pharmaceuticals and Products segment includes private label vaccine and pharmaceutical production, primarily for cattle but, also for other animals including small mammals and fish. All OVP products are sold by third parties under third party labels. Additionally, the Company generates non-product revenue from research and development projects for third parties, licensing of technology and royalties. The Company performs these research and development projects for both companion animal and livestock purposes. Summarized financial information concerning the Company’s reportable segments is shown in the following table (in thousands). 2004: Total revenue Operating income (loss) Total assets Capital expenditures Depreciation and amortization Amortization of intangible assets Interest expense 2005: Total revenue Operating income (loss) Total assets Capital expenditures Depreciation and amortization Amortization of intangible assets Interest expense Core Companion Animal Health Other Vaccines, Pharmaceuticals and Products Total $ $ $ $ $ $ 54,474 (5,704) 23,357 277 378 393 372 Core Companion Animal Health 56,604 (595) 22,848 931 846 157 652 13,217 1,464 15,367 1,013 959 — 318 Other Vaccines, Pharmaceuticals and Products 12,833 1,466 13,936 445 1,004 — 434 67,691 (4,240) 38,724 1,290 1,337 393 690 Total 69,437 871 36,784 1,376 1,850 157 1,086 Core Companion Animal Health Other Vaccines, Pharmaceuticals and Products Total 2006: Total revenue Operating income (loss) Total assets Capital expenditures Depreciation and amortization Amortization of intangible assets Interest expense $ $ 62,968 2,780 26,112 810 765 334 809 $ 12,092 295 12,383 379 906 — 435 75,060 3,075 38,495 1,189 1,671 334 1,244 68 Total revenue by principal geographic area was as follows (in thousands): United States Europe Other International Total Total assets by principal geographic areas were as follows (in thousands): United States Europe Other International Total For the Years Ended December 31, 2005 2004 2006 $ $ 59,452 4,484 3,755 67,691 $ $ 60,849 4,151 4,437 69,437 $ $ 63,828 5,974 5,258 75,060 2004 December 31, 2005 2006 $ $ 35,123 3,601 — 38,724 $ $ 33,414 3,370 — 36,784 $ $ 33,395 5,100 — 38,495 11.

Controls and Procedures. (a) Evaluation of Disclosure Controls and Procedures. Our management, with the participation of our chief executive officer and our chief financial officer, evaluated the effectiveness of our disclosure controls and procedures, as defined by Rule 13a-15 of the Exchange Act, as of the end of the period covered by this Annual Report on Form 10-K. Based on this evaluation, our chief executive officer and our chief financial officer have concluded that our disclosure controls and procedures are adequate to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure. (b) Changes in Internal Control over Financial Reporting. There was no change in our internal control over financial reporting that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. As of June 30, 2006, we did not meet the definition of “accelerated filer,” as defined by Rule 12b-2 of the Exchange Act and, thus, are not required by the Sarbanes-Oxley Act of 2002 to include an assessment of our internal control over financial reporting and attestation from our independent registered public accounting firm in our Annual Report on Form 10-K for our fiscal year ended December 31, 2006.

Confidential treatment has been requested with respect to the omitted portions. THIS AGREEMENT entered into as of this 16th day of February, 2001 (“Effective Date”), by and between ARKRAY Inc., a Japanese corporation, having its principal office at 57 Nishi Aketa-cho, Higashikujo, Minami-ku, Kyoto 601-8045, Japan (hereinafter referred to as “ARK”), and Heska Corporation, Delaware corporation having its principal office at 1613 Prospect Parkway, Fort Collins, Colorado 80525, U.S.A. (hereinafter referred to as “Heska”). DISTRIBUTION AGREEMENT WITNESSETH WHEREAS, ARK is a manufacturer and distributor of clinical diagnostic instruments and Heska is a manufacturer and/or distributor of hematology instruments, reagents and other products targeted to veterinary markets. WHEREAS, ARK desires to appoint Heska as a distributor and Heska wishes to obtain such distribution rights to market and sell Automated Clinical Chemistry Analyzer Model SP-4430 (hereinafter referred to as “Product”) as defined herein, effective from the date of the execution of this Agreement. NOW, THEREFORE, in consideration of the foregoing premises and of the mutual covenants herein contained, the parties hereby agree as follows: ARTICLE I ARK appoints Heska as a distributor to promote, market, service and sell Product effective from the date of execution of this Agreement, and Heska agrees to accept such appointment subject to and in accordance with the following terms and conditions. 1.1 Product Product means product to be comprised of Automated Clinical Chemistry Analyzer Model SP-4430 (“Analyzer”) and those related spare parts, consumables and reagents manufactured by ARK to be used to analyze blood in patients as listed in Appendix A and as amended from time to time by mutual written agreement of the parties. 1.2 Branding ARK and Heska agree that the brand name and logotype of Product shall be a combination of “ARKRAY” and “HESKA” in a format to be mutually agreed upon by the parties. 1.3 Distribution Right Heska shall have an exclusive right to promote, market, sell and distribute Product, with the right to appoint sub-distributors, in North America (“Territory”) and only in the veterinary market (“Field”). The exclusivity referred to in this Agreement applies between Heska and ARK or the ARK- appointed distributors. Heska agrees that, during the term of this Agreement, (a) Heska shall not develop or make commercially available or acquire a product(s) with features identical to Product, and (b) Heska shall not handle or otherwise provide any “off-brand” and/or “generic” form of spare part, consumables and reagents to be used with Product unless such consumables and reagents are not available from Arkray; provided, however, this section will not apply to common laboratory transfer pipettes, common QC serum materials and primary blood collection tubes that fit commercially available external centrifuges. 1.4 Sales Responsibility Heska assumes all sales responsibilities for Product to be sold in the Territory and Field under this Agreement. “Sales Responsibilities” as used herein includes all sales force training, maintenance and support activities, as well as pricing, advertising, promotion, and demonstration. ARK will provide Heska with specifications, test procedures and manuals written in English that may be reasonably necessary for Heska to fulfill its Sales Responsibilities. 1.5 Relationship of Parties Each party shall be considered an independent contractor of the other party. Nothing in this Agreement shall be construed as establishing a joint venture or partnership or principal/agent, or employee relationship. No party is authorized to make any statement, claim, representation or warranty or to act on behalf of any other party with respect to any of the provisions of this Agreement, except as provided for herein or as specifically authorized in writing by other party. 1.6 Term and Renewal This Agreement shall continue in full force and effective for a period of three (3) years from the date of execution of this Agreement and shall be automatically renewed for additional one year periods unless a party provides notice to the other party of its intent not to renew this Agreement at least one hundred eighty (180) days prior to the current expiration date of this Agreement, unless this Agreement is terminated earlier as set forth in Section 1.7. 1.7 Termination Either party may cancel this Agreement by a written notice at any time in the event that the other party shall have been in material breach of any of the provisions of this Agreement and such breach shall have been continued for sixty (60) days after such a written notice thereof was provided to the breaching party by the non-breaching party. Either of the parties may terminate this Agreement at any time without giving any notice to the other party if that party is declared insolvent or bankrupt by a court of competent jurisdiction. If Heska fails to meet the agreed upon minimum annual purchases for two (2) consecutive years, then Heska shall lose all rights to distribute Analyzer. However, ARK shall continue to supply Heska with Consumables as provided in Section 2.3. Upon any such termination of this Agreement, the terminating party may (but has no obligation to) cancel any and all unshipped sales orders concluded hereunder. Unless otherwise provided herein, each party waives any claims for compensation or damages in connection with such cancellation of undelivered Products from the other party. The provisions of Sections 2.3 (Spare Parts, Consumables and Reagents), 2.4 (Patents), 4.2 (Confidentiality), 4.3 (Indemnification), 4.6 (Publicity), and 4.10 (Law of Contract Jurisdiction) shall survive termination of this Agreement. ARTICLE II 2.1 Warranty and Quality ARK warrants that Product to be delivered hereunder shall be free and clear of any and all liens, encumbrances or defects in title and shall be conveyed to Heska with lawful and marketable title. ARK warrants that Product shall satisfy the performance specifications set forth in Appendix B. ARK will not make any changes to Product without first notifying Heska in writing at least ninety (90) days in advance of such changes and providing Heska with evidence that such changes do not alter the performance specifications of Product and obtaining Heska’s consent in writing. ARK shall input normal reference ranges for animals supplied by Heska in writing into the Analyzers without modification by ARK. In the event that Heska determines that any shipment of Product to be delivered to it hereunder fail/s to conform to the performance specifications set forth in Appendix B, Heska shall promptly notify ARK and reasonably specify the manner in which Product fail/s to conform. ARK shall have the rights to make its own inspection and evaluation of the allegedly non-conforming Product and shall notify Heska, within twenty one (21) days after receipt of such information, including samples of the allegedly non-conforming Product from Heska, whether it has confirmed and accepted Heska’s claim that Product are/is non- conforming. If ARK determines and confirms that Product are/is non-conforming, ARK shall replace, at no cost to Heska, the non-conforming Product at the earliest date after confirmation of Product non- conformance. ARK shall also bear the freight charges, insurance, duties and tariffs for return of all non-conforming Product to ARK from Heska. If, after evaluating the allegedly non-conforming Product, ARK believes that Product in question are/is conforming, ARK shall supply Heska with its written findings and request Heska to submit additional samples of Product to an independent third party, acceptable to both parties, for testing in accordance with and against the performance specifications set forth in Appendix B. The decision of such third party shall be final with respect to the alleged non-conforming Product and binding on both parties to this Agreement. If the decision of the third party is that Product are/is non-conforming, ARK shall pay the return freight, insurance, duties and tariffs with respect to Product shipped to Heska as well as all costs and expenses relating to the testing of Product by the independent third party. In addition, ARK shall supply Heska with a Certificate of Destruction certifying that Product have/has been destroyed in an environmentally safe manner. If the decision of the third party is that Product conform/s to the applicable specifications, Heska shall accept Product and shall be responsible for the return freight, insurance, duties, tariffs and all costs and expenses relating to the testing of Product by the independent third party. Each Product is warranted by ARK to be free from defects in materials and workmanship for a period of sixteen (16) months from the date of shipment from ARK to Heska. During the warranty period, ARK will provide Heska with all necessary warranty replacement parts at no charge. ARK’s warranty obligation under this Article is limited to the repair or replacement of Product. 2.2 Trademark ARK grants to Heska a limited license to use on a non-exclusive basis ARK’s trademarks and brand names as set forth in Appendix C for the purposes specified in this Agreement. Except as specified in this Section and Section 1.2, no party to this Agreement will derive any legal rights to the other party’s trademarks. No party shall adopt, use or register in any country, without the written consent of the other party, a trademark for any similar, related or competitive product which is likely to be confused with a trademark of the other party. 2.3 Spare Parts, Consumables and Reagents ARK agrees that spare parts, consumables and reagents used with Analyzer (collectively called “Consumables”) will continue to be furnished to Heska at the prices fixed on the basis of the price negotiation every year for a period of five (5) years following the last shipment of Analyzer from ARK to Heska as long as Heska continues to have exclusive distribution rights to sell Analyzer. Should Heska lose ARK’s exclusive distribution rights to sell Analyzer, ARK agrees to allow Heska to be a supplier of Consumables to Heska’s customers for a period of twelve (12) months from the loss of exclusive distribution rights to sell Analyzer. Thereafter, ARK agrees to supply Consumables to Heska’s customers during the time ARK sells Consumables in North America directly or through a distributor. 2.4 Patents ARK warrants and represents to Heska, and without admitting any infringement, to the best of its current actual knowledge neither Product of this Agreement nor its manufacture, use, importation or sale infringe upon any issued patent or proprietary rights held by a third party. ARK shall defend, indemnify and hold Heska and its subsidiary or affiliated companies, and customers thereof, harmless from any damages, including without limitation reasonable attorneys’ fees, with respect to any and all claims that the manufacture, use, rental or sale of any of Product of this Agreement infringes upon any patent or proprietary rights of a third party. 3.1 Orders and Forecasts ARTICLE III The forecast provided for below will include a firm purchase commitment covering the first five (5) months of the forecast. Therefore, Heska will issue periodic purchase orders within the terms specified below. Such purchase orders shall not bind ARK unless or until accepted by ARK. ARK shall notify Heska of its decision on acceptance within ten (10) days after receipt of a purchase order. Heska shall provide ARK, on a quarterly basis by the end of each Calendar quarter, a non-binding rolling one (1) year forecast of its anticipated purchases of Product. ARK shall keep Heska notified immediately of any events that may significantly impact ARK’s ability to deliver, such as interruptions by suppliers, labor troubles, discovered defects, and the like. ARK agrees to ship to Heska (i) Consumab1es within ninety (90) days of ARK’s acceptance of a purchase order for Consumab1es, and (ii) Analyzers within one hundred twenty (120) days of ARK’s acceptance of a purchase order for Analyzers. 3.2 Minimum Purchase ARK and Heska shall separately discuss and agree on a minimum annual purchase of Product to be made by Heska from ARK for every calendar year three (3) months prior to the beginning of every calendar year during the effective period of this Agreement. 3.3 Pricing ARK will sell Product to Heska in accordance with the prices agreed upon, which shall be denominated in Japanese yen. Upon thirty (30) day prior written notice from one party to the other, the parties agree to discuss in good faith any adjustment to the prices of Product in an attempt to reach a mutually satisfactory agreement. If a mutually satisfactory agreement cannot be reached, the prices of Product then in effect shall remain applicable. 3.4 Shipping of Products, Reagents, Spare Parts and etc. ARK will immediately confirm the receipt of each purchase order from Heska in order that Heska has assurance that each purchase order is duly received by ARK. ARK shall try its best efforts to ship all of Product ordered by Heska as specified by Heska. In the event of its inability to make a complete shipment as specified by Heska, ARK shall notify Heska immediately of the possible shipping date. Both parties shall discuss and amicably agree to adjust the shipping date if ARK’s shipping date causes Heska any inconvenience. Should ARK upon acceptance of a purchase order fail to ship Product from Japan within ten (10) business days of specified shipping dates twice within a twelve (12) month period, ARK agrees to renegotiate the annual minimum. 3.5 Payment Terms At Heska’s sole option, Heska will provide a letter of credit or prepay in Japanese yen one week in advance of the shipment of Products under a purchase order; provided Heska receives a timely firm shipment date in writing from ARK. Ark agrees to renegotiate the payment terms within twelve (12) months of the Effective Date. 3.6 Packing Product shall be labeled, packaged and shipped to Heska in accordance with the ARK’s quality standard to satisfy the requirements for Product Specifications set forth in Appendix B. Labels for Products shall be mutually agreed upon by the Parties. 3.7 Freight Insurance ARK will ship Heska Product ordered by Heska under the terms of FCA Osaka and/or Kobe, Japan as defined in Incoterms 2000. Heska shall be responsible for payment of all air and/or sea freight, insurance, duties and tariffs for shipments of Product to Heska, except as both parties agree.

The purpose of the Plan is to promote the long-term success of the Company and the creation of stockholder value by (a) encouraging Employees, Outside Directors and Consultants to focus on critical long-range objectives, (b) encouraging the attraction and retention of Employees, Outside Directors and Consultants with exceptional qualifications and (c) linking Employees, Outside Directors and Consultants directly to stockholder interests through increased stock ownership. The Plan seeks to achieve this purpose by providing for Awards in the form of Restricted Shares or Options (which may constitute incentive stock options or nonstatutory stock options). The Plan shall be governed by, and construed in accordance with, the laws of the State of Colorado (except their choice-of-law provisions). ARTICLE 2. ADMINISTRATION. 2.1 Committee Composition. The Plan shall be administered by the Committee. The Committee shall consist exclusively of two or more directors of the Company, who shall be appointed by the Board. In addition, the composition of the Committee shall satisfy: (a) Such requirements as the Securities and Exchange Commission may establish for administrators acting under plans intended to qualify for exemption under Rule 16b-3 (or its successor) under the Exchange Act; and (b) Such requirements as the Internal Revenue Service may establish for outside directors acting under plans intended to qualify for exemption under section 162(m)(4)(C) of the Code. The Board may also appoint one or more separate committees of the Board, each composed of one or more directors of the Company who need not satisfy the foregoing requirements, who may administer the Plan with respect to Employees and Consultants who are not considered officers or directors of the Company under section 16 of the Exchange Act, may grant Awards under the Plan to such Employees and Consultants and may determine all terms of such Awards. 2.2 Committee Responsibilities. The Committee shall (a) select the Employees, Outside Directors and Consultants who are to receive Awards under the Plan, (b) determine the type, number, vesting requirements and other features and conditions of such Awards, (c) interpret the Plan and (d) make all other decisions relating to the operation of the Plan. The Committee may adopt such rules or guidelines as it deems appropriate to implement the Plan. The Committee’s determinations under the Plan shall be final and binding on all persons. 1 ARTICLE 3. SHARES AVAILABLE FOR GRANTS. 3.1 Basic Limitation. Common Shares issued pursuant to the Plan may be authorized but unissued shares or treasury shares. The aggregate number of Options and Restricted Shares awarded under the Plan shall not exceed (a) 1,350,000 plus (b) the aggregate number of Common Shares remaining available for grants under the Predecessor Plans on March 15, 1997, plus (c) the additional Common Shares described in Sections 3.2 and 3.3. No additional grants shall be made under the Predecessor Plans after March 15, 1997. The limitation of this Section 3.1 shall be subject to adjustment pursuant to Article 9. 3.2 Annual Increase in Shares. As of January 1 of each year, commencing with the year 1998 and continuing through January 1, 2007, the aggregate number of Options and Restricted Shares that may be awarded under the Plan shall be increased by a number of Common Shares equal to the lesser of (a) 5% of the total number of Common Shares outstanding as of the next preceding December 3 1 or (b) 1,500,000. After the annual increase on January 1, 2007, there shall be no further annual increases under the Plan unless and until stockholder approval of such increase has been obtained. 3.3 Additional Shares. If Options granted under this Plan or under the Predecessor (Plans are forfeited or terminate for any other reason before being exercised, then the corresponding Common Shares shall become available for the grant of Options and Restricted Shares under this Plan. If Restricted Shares are forfeited, then the corresponding Common Shares shall again become available for the grant of NQOs and Restricted Shares under the Plan. The aggregate number of Common Shares that may be issued under the Plan upon the exercise of ISOs shall not be increased when Restricted Shares are forfeited. ARTICLE 4. ELIGIBILITY. 4.1 Nonstatutory Stock Options and Restricted Shares. Only Employees, Outside Directors and Consultants shall be eligible for the grant of NQOs and Restricted Shares. 4.2 Incentive Stock Options. Only Employees who are common-law employees of the Company, a Parent or a Subsidiary shall be eligible for the grant of ISOs. In addition, an Employee who owns more than 10% of the total combined voting power of all classes of outstanding stock of the Company or any of its Parents or Subsidiaries shall not be eligible for the grant of an IS0 unless the requirements set forth in section 422(c)(6) of the Code are satisfied. ARTICLE 5. OPTIONS. 5.1 Stock Option Agreement. Each grant of an Option under the Plan shall be evidenced by a Stock Option Agreement between the Optionee and the Company. Such Option shall be subject to all applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan. The Stock Option Agreement shall specify whether the Option is an IS0 or an NQO. The provisions of the various Stock Option Agreements entered into under the Plan need not be identical. Options may be granted in 2 consideration of a cash payment or in consideration of a reduction in the Optionee’s other compensation. A Stock Option Agreement may provide that a new Option will be granted automatically to the Optionee when he or she exercises a prior Option and pays the Exercise Price in the form described in Section 6.2. 5.2 Number of Shares. Each Stock Option Agreement shall specify the number of Common Shares subject to the Option and shall provide for the adjustment of such number in accordance with Article 9. Options granted to any Optionee in a single fiscal year of the Company shall not cover more than 500,000 Common Shares, except that Options granted to a new Employee in the fiscal year of the Company in which his or her service as an Employee first commences shall not cover more than one million Common Shares. The limitations set forth in the preceding sentence shall be subject to adjustment in accordance with Article 9. 5.3 Exercise Price. Each Stock Option Agreement shall specify the Exercise Price; provided that the Exercise Price under an IS0 shall in no event be less than 100% of the Fair Market Value of a Common Share on the date of grant and the Exercise Price under an NQO shall in no event be less than 85% of the Fair Market Value of a Common Share on the date of grant. In the case of an NQO, a Stock Option Agreement may specify an Exercise Price that varies in accordance with a predetermined formula while the NQO is outstanding. 5.4 Exercisability and Term. Each Stock Option Agreement shall specify the date when all or any installment of the Option is to become exercisable. The Stock Option Agreement shall also specify the term of the Option; provided that the term of an IS0 shall in no event exceed 10 years from the date of grant. A Stock Option Agreement may provide for accelerated exercisability in the event of the Optionee’s death, disability or retirement or other events and may provide for expiration prior to the end of its term in the event of the termination of the Optionee’s service.

If an Option or SAR becomes fully vested and exercisable in lieu of assumption or substitution in the event of a Change in Control, the Company shall notify the Participant in writing or electronically that the Option or SAR shall be fully vested and exercisable (subject to the consummation of the Change in Control) for a period of fifteen (15) days from the date of such notice, and the Option or SAR shall terminate upon the expiration of such period. (c) For the purposes of this Section 9.1.1, the Option or SAR shall be considered assumed if, following the Change in Control, the option or right confers the right to purchase or receive, for each Share subject to the Option or SAR immediately prior to the Change in Control, the consideration (whether stock, cash, or other securities or property) received in the 13 Change in Control by holders of Shares for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the Change in Control is not solely common stock of the successor corporation or its parent, the Committee or the Board may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Option or SAR, for each Share subject to the Option or SAR, to be solely common stock of the successor corporation or its parent equal in fair market value to the per share consideration received by holders of Shares in the Change in Control, as determined on the date of the Change in Control. 9.1.2 Restricted Stock. In the event of a Change in Control, any Company repurchase or reacquisition right with respect to outstanding Shares of Restricted Stock held by the Participant will be assigned to the successor corporation.

To the extent this option is designated an incentive stock option and it does not qualify as an incentive stock option under applicable laws, it will be treated as a nonstatutory option. This option vests and becomes exercisable in installments, as shown in the Notice of Stock Option Grant. In addition, in the event your service as an Employee, Director or Consultant terminates because of your death, your option shall become fully vested and exercisable as to the total number of shares subject thereto immediately upon the date of your death. No additional shares become vested after your Termination of Service and the option shall terminate as to any shares that are unvested as of the end of business on the date of your Termination of Service. Term This option expires in any event at the close of business at Company headquarters on the day before the 10th anniversary of the Date of Grant, as shown in the Notice of Stock Option Grant. (It will expire earlier if your service terminates, as described below.) Regular Termination In the event of your Termination of Service for any reason except death or Disability, then this option will expire as to unexercised vested option shares at the close of business at Company headquarters on the date three months after your termination date. The Company determines when your service terminates for this purpose. Death In the event of your Termination of Service because of your death or your death within three months after your Termination of Service, then this option will expire as to unexercised vested option shares at the close of business at Company headquarters on the date one year after your date of death. 1 Disability Leaves of Absence Change in Control In the event of your Termination of Service because of your Disability, then this option will expire as to unexercised vested option shares at the close of business at Company headquarters on the date one year after your termination date. Vesting of this option shall be suspended during any unpaid leave of absence unless continued vesting is required by the terms fo the leave or by applicable law. This option shall vest and become exercisable in full if (i) the Company is subject to a Change in Control, (ii) this option is not continued by the Company and (iii) this option is not either assumed by the surviving corporation or its parent or substituted for by the surviving corporation’s or its parent’s issuing its own option in replacement of this option. Restrictions on Exercise The Company will not permit you to exercise this option if the issuance of shares at that time would violate any law or regulation, and the Company will have no liability for failure to issue or deliver any shares upon exercise of this option if the issuance or delivery would violate any law or regulation as determined by the Company in consultation with its legal counsel. This option may not be exercised for a fraction of a share. Notice of Exercise When you wish to exercise this option, you must notify the Company by filing the proper “Notice of Exercise” form at the address given on the form. Your notice must specify how many shares you wish to purchase. The exercise will be effective when the Company receives the Notice of Exercise with the option exercise payment described herein. If someone else wants to exercise this option after your death, that person must prove to the Company’s satisfaction that he or she is entitled to do so. Form of Payment When you submit your notice of exercise, you must include payment of the option exercise price for the shares you are purchasing. Payment may be made in one (or a combination of two or more) of the following forms: · Cash, check or wire transfer. · Certificates for shares of Company stock that you own, along with any forms needed to affect a transfer of those shares to the Company. The value of the shares, determined as of the effective date of the option exercise, will be applied to the option exercise price. However, the Company may restrict your ability to surrender shares of Company stock (including your ability to surrender any particular shares of Company Stock held by you) in payment of the 2 exercise price if your doing so would result in the Company’s recognizing additional compensation expense with respect to this option for financial reporting purposes. · Irrevocable directions to a securities broker approved by the Company to sell all or part of your option shares and to deliver to the Company proceeds from the sale in an amount sufficient to pay the option exercise price and any withholding taxes. (The balance of the sale proceeds, if any, will be delivered to you.) The directions must be given by signing a special “Notice of Exercise” form provided by the Company. Withholding Taxes and Stock Withholding You will not be allowed to exercise this option unless you make arrangements acceptable to the Company to pay any withholding taxes that may be due as a result of the option exercise. These arrangements may include (with the Company’s approval) withholding shares of Company stock that otherwise would be issued to you when you exercise this option. The value of these shares, determined as of the effective date of the option exercise, will be applied to the withholding taxes. Restrictions on Resale Transfer of Option By signing this Agreement, you agree not to sell any option shares at a time when applicable laws, Company policies or an agreement between the Company and its underwriters prohibit a sale. This restriction will apply as long as you are an Employee, Consultant or Outside Director of the Company or a Subsidiary. Prior to your death, only you may exercise this option. You cannot sell, transfer, pledge or assign this option. For instance, you may not sell this option or use it as security for a loan. You may, however, dispose of this option in your will, by the laws of descent and distribution or through a beneficiary designation. Retention Rights Stockholder Rights Regardless of any marital property settlement agreement, the Company is not obligated to honor a notice of exercise from your former spouse, nor is the Company obligated to recognize your former spouse’s interest in your option in any other way. Neither your option nor this Agreement give you the right to be employed or otherwise retained by the Company in any capacity. The Company reserves the right to terminate your service at any time, with or without cause. You, or your estate or heirs, have no rights as a stockholder of the Company until you have exercised this option by giving the required notice to the Company and paying the exercise price. 3 Applicable Law The Plan and Other Agreements This Agreement will be interpreted and enforced under the laws of the State of Colorado (without giving effect to its conflict of laws provisions). The 2003 Equity Incentive Plan is incorporated in this Agreement by reference. Unless otherwise defined herein, all capitalized terms herein have the same defined meanings as in the 2003 Equity Incentive Plan. In the event of any conflict between the terms and provisions of the Plan and this Agreement, the Plan terms and provisions shall govern.

Any prior agreements, commitments or negotiations concerning this option are superseded. This Agreement may be amended only by another written agreement, signed by both parties.

(ii) For the purposes of this Employment Agreement, “change of control” is defined as the merger, acquisition or sale of Company or all or substantially all of its assets with, into, or to a previously unaffiliated third party entity, other than a merger in which the shareholders of Company prior to the merger, by reason of such shareholdings, own more than 50% of the outstanding shares of the company after the merger. 2 (iii) The parties agree that for the purposes of this Employment Agreement, an “involuntary termination” due to a “change of control” will be deemed to have occurred when Employee is no longer employed by the Company’s successor following a “change of control” because the Employee’s position is eliminated within nine (9) months of the “change of control” or when Employee’s job responsibilities are materially and negatively changed within nine (9) months of the “change of control”, and Employee elects to resign. (iv) In the event that severance pay is due to Employee as a result of the “involuntary termination” of her employment without “cause” due to a “change of control”, Employee will be paid one (1) year’s “base salary” at the rate in effect immediately prior to the termination in twelve equal monthly installments (subject to all applicable taxes and other deductions), with the first such installment due 15 days after the date of such termination and with the following eleven installments due no later than monthly thereafter on Company’s then regular payroll dates. The Company will also pay the employer contribution and administrative cost of the health insurance premiums for the medical and dental insurance coverage previously maintained by the Company for Employee and her eligible dependents during this one year period or until Employee is provided or obtains medical and dental insurance coverage by another employer or entity, whichever first occurs. (d) Termination “For Cause”; Voluntary Resignation. (i) If Company or its successor terminates Employee for “cause” or if Employee’s employment terminates for any reason other than a termination by the Company “without cause” (as set forth in paragraph 6(b)) or due to a “change of control” (as set forth in Paragraph 6(c)), Employee will not be entitled to any severance pay and shall only receive pay and benefits which Employee earned as of the date of termination. (ii) The parties agree that for the purposes of this Employment Agreement, a termination for “cause” will be deemed to have occurred when Company terminates Employee’s employment because of the occurrence of any of the following events: (A) Employee shall refuse to accept a change or modification of his title, duties or responsibilities by senior management and/or the Board of Directors; (B) Employee shall refuse to accept a reasonable transfer not arising from a change in control to a position with comparable responsibility and salary with any affiliated company that does not involve commuting more than fifty (50) miles each way from the Company headquarters in the Fort Collins, Colorado area; (C) Employee shall die, be adjudicated to be mentally incompetent or become mentally or physically disabled to such an extent that Employee is unable to perform his duties under this Employment Agreement for a period of ninety (90) consecutive days; (D) Employee shall commit any breach of his obligations under this Agreement; 3 (E) Employee shall commit any breach of any material fiduciary duty to Company; (F) Employee shall be convicted of, or enter a plea of nolo contendere to, any crime involving moral turpitude or dishonesty, whether a felony or misdemeanor, or any crime which reflects so negatively on Company as to be detrimental to Company’s image or interests; (G) Employee shall commit insubordination or refusal to comply with any request of his supervisor or the Board of Directors of Company relating to the scope or performance of Employee’s duties; (H) Employee shall possess any illegal drug on Company premises or Employee shall be under the influence of illegal drugs or abusing prescription drugs or alcohol while on Company business or on Company premises; or (I) Employee shall conduct herself in a manner that, in the good faith and reasonable determination of the Senior Management and/or the Board of Directors, demonstrates Employee’s unfitness to serve. 7. Proprietary Information. Employee agrees that, if she has not already done so, she will promptly execute Company’s standard employee proprietary information and assignment of inventions agreement. 8. Arbitration; Attorneys’ Fees. If any dispute arises under this Agreement or by reason of any asserted breach of it, or from the Parties’ employment relationship or any other relationship, the Company, at its sole discretion, may elect to have the dispute resolved through arbitration, so long as all of the arbitrator’s fees and expenses are borne exclusively by the Company. The arbitration shall be conducted pursuant to the rules of the American Arbitration association, with the arbitrator being selected by mutual agreement of the parties. Regardless of whether the dispute is resolved through arbitration or litigation, the prevailing party shall be entitled to recover all costs and expenses, including reasonable attorneys’ fees, incurred in enforcing or attempting to enforce any of the terms, covenants or conditions, including costs incurred prior to commencement of arbitration or legal action, and all costs and expenses, including reasonable attorneys’ fees, incurred in any appeal from an action brought to enforce any of the terms, covenants or conditions.

I agree, however, that, during the Consulting Period, I will not, for my account or as an officer, member, employee, consultant, representative or advisor of another, engage in or contribute my knowledge to engineering, development, manufacturing, research, business analysis or sales relating to any product, equipment, process or material that relates in any way to the Confidential Information of the Company without the written permission of the Company. The foregoing provision, however, shall not prohibit me from engaging in any work at any time after the Consulting Period, provided that Confidential Information will not be involved in such work. The provisions of this Section 6.1 will not be construed as limiting to any extent my continuing obligations under any other section of this Agreement. 6.2 No Conflict With Prior Agreements. I represent and warrant to the Company and its affiliates that my retention by the Company and my performance of my obligations under this Agreement do not conflict with any prior obligations to third parties, including former employers.

Should either party default in the performance of this Agreement or materially breach any of its obligations under this Agreement the non-breaching party may terminate this Agreement immediately if the breaching party fails to cure the breach within 5 business days after having received written notice by the non-breaching party of the breach or default. In the event of termination for any reason or for default the Consultant shall be paid for any portion of services rendered pursuant to Exhibit A that have been performed prior to the termination. 8.0 Legal Relationship. My relationship with the Company is that of an independent contractor and not as an employee, as such is defined in C.R.S. 8-40-202(2)(a), nor an agent of the Company. I will not be entitled to any benefits or compensation from the Company except as set forth in this Agreement. I agree that I am responsible for direct payment of any federal or state taxes on the compensation paid to me under this Agreement.

This Agreement shall be governed by the laws of the State of Colorado. Each article shall be independent and separable from all other articles, and the invalidity of an article shall not affect the enforceability of any of the other articles. 11.0 Remedies. I recognize that any violation of this Agreement by me would cause the Company irreparable damage for which other remedies would be inadequate, and I therefore agree that the Company shall have the right to obtain, in addition to all other remedies, such injunctive and other equitable relief from a court of competent jurisdiction as may be necessary or appropriate to prevent any violation of this Agreement. 12.0 Waiver. The Company’s waiver or failure to enforce the terms of this Agreement or any similar agreement in one instance shall not constitute a waiver of its rights hereunder with respect to other violations of this or any other agreement. 13.0 Entire Agreement.

In order to avail itself of its rights hereunder Heska shall have given Boule notice in writing of the non-conforming or defective Product within the Warranty Period. 6 [***] — Certain information on this page have been omitted and filed separately with the Securities and Exchange Commission.

Any Confidential Information and/or proprietary information shall be in writing and clearly designated Confidential, or if initially disclosed orally, confirmed in writing within thirty (30) days of disclosure. 7.2 Scope of Obligation. Nothing in this Article 7 shall be construed to impose a confidentiality obligation on a Party in connection with any information to the extent such information (a) is at the time of disclosure already known to the receiving party (as clearly established by such Party’s prior written records); (b) is at the time of disclosure or subsequently becomes part of the public domain through no fault, act, or omission of the receiving Party; (c) is subsequently disclosed to the receiving Party by a third party whose receipt and disclosure of such Confidential Information does not, according to the receiving Party’s knowledge, constitute a violation of any confidentiality obligation; (d) is independently developed by the receiving Party by employees having no access to or knowledge of Confidential Information received; or (e) is required by a court or government agency; provided that the disclosing party shall use reasonable efforts to provide the other party notice in writing of any proposed disclosure under this subsection and an opportunity to object to the disclosure or seek confidential treatment thereof. 7.3 Return of Information. The receiving Party shall return all Confidential Information provided by the disclosing Party, and any documents or materials incorporating such Confidential Information, upon the expiration or termination of this Agreement; provided, however, one copy of all such Confidential Information may be retained in the legal files of the receiving Party to assure compliance with the confidentiality and non-use provisions of this Article 7. 8. Term and Termination 8.1 Term. Unless terminated earlier as provided herein, this Agreement shall be effective from the Effective Date and shall remain in effect until December 31, 2008.

Should Boule elect not to repurchase such Products, Heska shall have the right, but not the obligation, to sell Products in stock. Upon termination of this Agreement, Boule shall continue to supply Consumables to Heska as provided in Section 3.6. 8.4 Dispute Resolution. The Parties covenant and agree in good faith to attempt for a period of sixty (60) days to resolve any disputes which may arise in connection with this Agreement through negotiation and settlement prior to giving notice of termination or bringing any legal action against the other Party in connection with this Agreement. During such negotiations, the Parties shall also consider the possibility of using alternative dispute resolution methods, including arbitration and mediation, if the Parties are unable to resolve the dispute. The provisions of this section shall not apply if one Party refuses to negotiate the dispute in good faith or if more prompt legal action is required to avoid material loss or damage. Failure to resolve a dispute by negotiated settlement shall not prejudice any subsequent legal action with respect thereto. 9. Miscellaneous 9.1 Relationship of Parties. The relationship of Boule to Heska under this Agreement is intended to be that of independent contractor. Nothing contained in this Agreement is intended or is to be construed so as to constitute Boule and Heska as employer/employee or principal/agent, or the employees or the agents of any Party hereto as employees or agents of the other Party hereto.

This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective successors and assigns; provided, however, that neither Party shall have the right to transfer or assign its interest in this Agreement without the prior written consent of the other Party, except that either Party may make such transfer or assignment, to a partner, subsidiary or entity otherwise controlling, controlled by or under common control with such Party, or to an entity acquiring all or substantially all relevant assets of a Party to which this Agreement pertains. No transfer or assignment will relieve the transferor or assignor of any liability or obligations hereunder. 9 [***] — Certain information on this page have been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. 9.3 Waiver of Performance. A failure of a Party hereto at any time to require performance by the other Party hereto of any provision hereto required to be performed by such other Party, will in no way affect the right of the first party to require such performance at any time thereafter. The waiver of any breach of any provision hereto will in no way be construed as a waiver of any succeeding breach of such provision or a waiver of the provision itself. 9.4 Severability. In the event any provision of this Agreement shall be invalid, void, illegal, or unenforceable, the remaining provisions hereof nevertheless will continue in full force and effect without being impaired or invalidated in any way. 9.5 Survival.

Box 42056 SE-126 13 Stockholm, Sweden Attention: Ernst Westman, President Re: Supply and Distribution Agreement (“Distribution Agreement”) by and between Heska Corporation (“Heska”) and Boule Medical AB (“Boule”) dated June 17, 2003 Dear Mr. Westman: This letter confirms our agreement to interpret and supplement the Distribution Agreement as follows (capitalized terms not otherwise defined herein have the meanings ascribed to them in the Distribution Agreement): 1. Pricing and Payment. Appendix Al and Appendix A2 of the Distribution Agreement are hereby deleted in their entirety and replaced with Appendices AI, A2, A3, A4 and A5 attached hereto. The last sentence of the first paragraph of Section 4.1 of the Distribution Agreement is hereby amended to read as follows: “All prices and fees shall be defined in Euros and/or US Dollars, as provided in Appendices A2, A3, A4 and A5.” 2. Appendix C. Appendix C to the Distribution Agreement is attached hereto. 3. Returns. Notwithstanding any provision of Section 6.1 (c) of the Distribution Agreement to the contrary, Boule shall reimburse Heska for the cost and expense of returning non-conforming or defective Product as contemplated therein. 4. Indemnification. Boule and Heska agree that the following phrase shall be deleted at the end of the second sentence of Section 6.5 of the Distribution Agreement and shall have no further force and effect: “or any of its customers or from a defect for which Boule is not responsible”. 5. Consumable Sales after Termination. Unless Boule terminates the Distribution Agreement pursuant to Section 8 .2 thereof, Heska may purchase Consumables following termination of the Distribution Agreement as provided in Section 3.6 thereof, and for the avoidance of doubt, Heska’s right to make such purchases shall not obligate Heska to comply 16 with the restrictions set forth in Section 2.3 thereof. However, if Heska sells non-Boule spare parts, consumables or reagents for the Analyzer following termination of the Distribution Agreement (other than due to Boule’s failure to timely fill Heska’s orders for Consumables), then Heska’s right to purchase Consumables shall expire. 6. Sale of Refurbished ABC Systems and Scil Inventory. Notwithstanding any provision of the Distribution Agreement to the contrary, including but not limited to Section 2.3 thereof, Boule agrees that Heska shall have the right, but not the obligation, to obtain and refurbish used ABC instruments (“Refurbished ABC Systems”) and to sell such Refurbished ABC Systems within the Territory at any time after the date of this Amendment. In addition, Heska shall have the right, but not the obligation, to sell its inventory of instruments and reagents purchased from Scil Animal Care Company, America, Inc., within the Territory, at any time after the effective date of this Amendment. Heska shall provide monthly reports of sales of both new ABC Systems and Refurbished ABC Systems to Boule. This letter will constitute a written agreement amending the Distribution Agreement as contemplated by Section 9.10 thereof. If there is a conflict between the terms of this letter and the Distribution Agreement, this letter shall control.

In furtherance of this exclusive grant to Heska and its Affiliates, i-STAT hereby agrees to use its commercially reasonable efforts to ensure that any Products Sold outside the Field are not Sold directly or indirectly by i- STAT distributors to End Users. Nothing contained in this Agreement shall limit or be interpreted to limit i-STAT or i-STAT’s Affiliates from directly selling products not listed on Exhibit 1.29 in the Territory. 2.2 Non-exclusive Appointment in Japan. As of the Effective Date and subject to Section 2.4 and Section 2.5 below, i-STAT hereby appoints Heska and its Affiliates for the Term as i-STAT’s non-exclusive distributor of Products in the Field in Japan, and Heska accepts such appointment. Heska shall have the non-exclusive right to market, promote, Sell and distribute Products in Japan for use in the Field. 2.3 Heska’s Obligations. Heska shall purchase Products for distribution and Sale in the Field in the Territory exclusively from i-STAT. Heska shall maintain, at its own expense, a commercially reasonable inventory of Products for the Sale, promotion and delivery of the Products and for managing customer satisfaction with the Products.

The Cartridge units Sold outside the Field shall not be included in Cartridge Purchases for the purpose of meeting the minimum purchase requirements of Sections 2.4 and 2.5. 6 [***] — Certain information on this page have been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. 2.4 Minimum Purchase Requirements during the Initial Term. Subject to Sections 2.6, 2.7 and 2.9, Cartridge Purchases shall be greater than or equal to the Base Cartridge Target for each Contract Year during the Initial Term, which, for purposes of this Agreement, shall be as set forth in the following Table 2.4; provided, that Cartridge Sales shall be at least ninety-five percent (95%) of Cartridge Purchases during such Contract Year. Contract Year Balance of 2004 2005 2006 2007 2008 2009 Table 2.4 Base Cartridge Target [***] [***] [***] [***] [***] [***] For example, if Heska has 2007 Cartridge Purchases of [***] and 2007 Cartridge Sales of [***], Heska shall have fulfilled the requirements of this Section 2.4 ([***] Cartridge Purchases and Cartridge Sales are 95.3% Cartridge Purchases). In a separate example, if Heska has 2007 Cartridge Purchases of [***] and 2007 Cartridge Sales of [***], Heska shall not have fulfilled the requirements of this Section 2.4 (since Heska would have met the Cartridge Purchases requirement, but would have Cartridge Purchases of 94.9% of Cartridge Sales, less than the required 95%). 2.5 Minimum Purchase Requirements during any Extension Term. Subject to Sections 2.6, 2.7 and 2.9, Cartridge Purchases shall be greater than or equal to the Base Cartridge Target for each Contract Year during any Extension Term, which for purposes of this Agreement, shall be calculated as set forth in the following Table 2.5; provided, that Cartridge Sales shall be at least ninety-five percent (95%) of Cartridge Purchases during such Contract Year.

In this example, the 2011 Base Cartridge Target will be equal to [***], calculated as follows: [***]. 2.6 Implications of Failure to Meet Minimum Purchase Requirements. i-STAT’s sole remedy for Heska’s failure to meet the Base Cartridge Target in Sections 2.4 or 2.5 in any Contract Year shall be to terminate this Agreement upon prior written notice to Heska as set forth in Section 2.13; provided, however, that i-STAT shall meet with Heska to discuss under what terms and conditions, if any, Heska may continue to distribute Products hereunder; and provided, further, that such failure to meet the Base Cartridge Target shall not be considered as a breach of this Agreement. 2.7 Failure to Supply Minimum Purchase Requirements. If during any Contract Year, i-STAT is unable to supply Cartridges properly forecasted and ordered hereunder pursuant to Article 3, the Base Cartridge Target for such Contract Year shall be reduced by the number of such Cartridges ordered by Heska pursuant to the terms of this Agreement and not supplied by i-STAT hereunder during such Contract Year. i-STAT, shall consider in good faith the impact of a material interruption in supply on Heska’s ability to achieve future Base Cartridge Targets in subsequent Contract Years and shall consider in good faith reasonable adjustments to Base Cartridge Targets proposed by Heska for such subsequent Contract Years; provided, however, that any decision regarding any reduction to future Base Cartridge Targets shall be at i-STAT’s sole discretion. 2.8 Right of First Offer. As long as Heska is i-STAT’s exclusive distributor of Products in the Field in the Territory, i-STAT shall, prior to offering any other or new products to any Third Party for resale in the Field in the Territory, first offer in writing (which for the purposes of this Section 2.8 may be by e-mail) to Heska the opportunity to negotiate with i-STAT in good faith to include such products as a Product hereunder on such terms and conditions as are mutually acceptable to the Parties. 2.9 Discontinued Products. i-STAT shall have the right to discontinue the manufacture of any Product hereunder. If i-STAT, in its sole discretion, decides to discontinue the manufacture of any Product, i-STAT shall: (a) provide written notice to Heska as follows: (i) for Analyzers, upon twelve (12) months’ prior written notice; and (ii) for all other Products, upon one hundred eighty (180) days’ prior written notice; and (b) negotiate in good faith with Heska an adjustment to the Base Cartridge Targets set forth in Sections 2.4 and 2.5; provided, that no adjustment shall be made if a discontinued Product is replaced by an equivalent Product at an equivalent price. If the 8 Parties are unable to agree on an adjustment, if any, to the Base Cartridge Targets as a result of good faith negotiations under clause (b) of the preceding sentence, they will follow the procedures set forth in Section 11.9 to establish an adjustment, if any. i-STAT may materially alter the performance of any or all of the Products upon ninety (90) days’ prior written notice to Heska. i-STAT shall use commercially reasonable efforts to provide to Heska reasonable quantities of repair and/or replacement parts, on an as needed basis, for Analyzers for at least three (3) years from the date of discontinuance of manufacture or sale of Analyzers or introduction of a materially altered Product for which parts are not interchangeable. i- STAT also shall use commercially reasonable efforts to consult with Heska prior to any discontinuance of the manufacture of any Product or material alteration of any Product where such alteration, in i-STAT’s reasonable opinion, would impact applicable regulatory approvals of Heska and / or marketing of the Products by Heska. 2.10 Selling Price. Heska, in its sole discretion, shall determine the final sales price of Products Sold by Heska to Third Parties in the Field in the Territory, and no other term or provision in this Agreement shall be interpreted or deemed to provide i-STAT with any right to determine the final sales price of Products Sold by Heska hereunder. Heska or its appointed Dealers solely shall be responsible for seeking and obtaining all pricing approvals from all applicable authorities in those countries in the Territory where Heska is distributing Products in the Field. 2.11 Heska’s Sales Efforts. Heska shall use commercially reasonable efforts to offer for Sale, Sell, have Sold, use, have used, market, have marketed, distribute, have distributed and import Products in the Field in the Territory, as more fully set forth in Article 4. 2.12 Appointment of Dealers. Heska shall have the right to appoint Dealers for the sale of the Products in the Field in the Territory. Heska agrees that, if it enters into an agreement or arrangement with any Dealer to allow such Dealer to offer for Sale, Sell, have Sold, use, have used, market, have marketed, distribute, have distributed, import and have imported Products in the Field in any country or region of the Territory, Heska shall restrict such Dealer’s activities to sales of Products in the Field for use in the Field by affirmatively restricting the Dealer from reselling Products to Third Parties outside the Field. Heska shall name i-STAT as the “third party beneficiary” for the purposes of enforcing this provision in any agreement or arrangement with a Third Party for Sale of Products in the Field. 2.13 Termination Notice Provisions. In the event that i-STAT exercises its right to terminate this Agreement in any given Contract Year for failure to meet the Base Cartridge Target in such Contract Year pursuant to Section 2.6, such termination shall be effective upon expiration of the Notice Period, determined as follows: 9 [***] — Certain information on this page have been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. (a) Six (6) months if [***]; (b) Twelve (12) months if [***]; (c) Eighteen (18) months if [***]; (d) Twenty-four (24) months if [***]; or (e) Thirty-six (36) months if [***]. In order to terminate the Agreement pursuant to Section 2.6, i-STAT must give written notice during the Notice Date Time. Upon receipt of written notice, Heska’s distributorship rights in the Field in the Territory shall become non-exclusive and remain non-exclusive throughout the Notice Period. For example, Heska has [***], Heska receives written notice of termination from i-STAT on January 15, 2008 and the Parties meet to discuss this situation on February 1, 2008 but cannot agree on amended terms under which Heska would continue to distribute Products. Pursuant to Sections 1.8 and 1.27, [***], which under Section 2.13, results in a Notice Period of twenty-four (24) months. Thus, in this example, the Agreement would terminate on January 15, 2010. 2.14 Most Favored Pricing. If, during any time period in which Heska is a non-exclusive distributor hereunder (including any time period set forth in Section 2.13), i-STAT shall sell Products in the Field in the Territory to any other distributor, dealer or Third Party at a price lower than the Purchase Price then paid by Heska hereunder (the “Most Favored Price”), then i-STAT shall give Heska prior written notice of the Most Favored Price and the period it is to be in effect and Heska shall be entitled to such Most Favored Price for such Product for so long as such lower price is in effect for any other distributor, dealer or Third Party in the Field in the Territory. 2.15 Restoration of Exclusivity and Cancellation of Termination. If, following any Contract Year in which Cartridge Purchases were less than the Base Cartridge Target, Heska’s Cartridge Purchases for the subsequent Contract Year are equal to or greater than Base Cartridge Target for the subsequent Contract Year, i-STAT shall consider in good faith restoring exclusivity to Heska as described in Section 2.1 and canceling the notice of termination previously sent to Heska; provided, however, that such restoration of exclusivity shall be only to the extent i-STAT has not made alternative contractual 10 arrangements that would preclude restoring Heska’s exclusivity in any part of the Territory. 2.16 Competitive Products. In furtherance of its duties and in recognition of the unique healthcare and related responsibilities in connection with the distribution of the Products, during the Term Heska shall not anywhere in the Territory promote, market, distribute or Sell any hand held device performing any tests performed by the Products, including new Products, if any, added to this Agreement pursuant to the terms and conditions set forth in this Agreement. Heska shall exclusively use the i-STAT control products set forth on Exhibit 1.29 unless i-STAT gives prior written approval for substitution. 2.17 EU Commission Directive. In accordance with the EU Commission Directive on Vertical Agreements, the covenant not to sell competitive products set forth in Section 2.16 for countries in the European Union (“EU”) shall be for no longer than five (5) years after the Effective Date. Heska agrees that if Heska has maintained exclusivity as set forth in Sections 2.4 and 2.5 during the Term, that Heska will meet with i-STAT to negotiate in good faith the terms, if any, under which the covenant not to sell competitive products in the EU may be extended (if any). ARTICLE 3 — MANUFACTURE, SUPPLY AND DELIVERY OF PRODUCTS 3.1 Manufacture, Sale and Purchase of Products. During the Term, i-STAT shall use commercially reasonable efforts to manufacture or have manufactured, release, sell and deliver to Heska those units of Products as are consistent with the forecasting process, lead times and terms and conditions of this Agreement and as are ordered by Heska hereunder. i-STAT shall manufacture or have manufactured, release, sell and deliver each such Product in accordance with each Product’s Specifications and all applicable rules and regulations applicable to the manufacture or sale of Products in the Territory in the Field, including as applicable, those rules and regulations of the FDA, including QSRs (including applicable cGMPs), and in accordance with all other applicable laws and regulations of countries in which Heska sells Products. 3.2 Rolling Forecasts. Thirty (30) days after the Effective Date, Heska shall provide i-STAT with a monthly forecast of its requirements of the Products for the first full Contract Year. On or before the fifth (5th) day prior to the beginning of each subsequent calendar month during the Term, Heska shall provide i-STAT with a rolling 12-month forecast, the first three (3) months of which will be firm purchase orders binding on Heska, the last nine (9) months of each shall consist of Heska’s best estimate forecast of its requirements of Products. 3.3 Product Orders. Heska shall order Products on purchase orders consistent with the process set forth in Section 3.2. All purchase order forms shall specify the quantities of 11 [***] — Certain information on this page have been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. each Product ordered, requested delivery dates, the identity of Products ordered, Product price, and delivery and shipping instructions including carrier selected. All orders will be governed by the terms of this Agreement. To the extent that any purchase order, confirmation of acceptance or other document contains terms in conflict with, or in addition to, the terms of this Agreement, such conflicting or additional terms shall not be binding on the Parties unless agreed upon in advance by the Parties. 3.4 Acceptance of Purchase Orders. i-STAT shall within five (5) Business Days notify Heska of any purchase order (or partial purchase order) accepted, rejected, or delayed, and the reason for any such rejection or delay. No purchase order shall be binding upon i-STAT until accepted by i-STAT. Purchase orders not rejected within five (5) Business Days shall be deemed accepted. Heska may not modify any purchase order after its acceptance by i-STAT without i-STAT’s prior consent. All purchase orders shall provide i-STAT with no less than ninety (90) days notice to the requested shipping date from i-STAT after receipt of the purchase order. Heska understands and agrees that optimum dating of Products shipped cannot be assured for Products shipped in connection with purchase orders placed less than ninety (90) days prior to the requested shipment date of Product from i-STAT. 3.5 Firm Order Changes. If, before submitting a purchase order form to i-STAT, Heska requests an increase to binding forecasts for the three (3) month firm forecast timeframe and such increase is no more than one hundred twenty percent (120%) of the amount of Products (on a Product-by-Product basis) originally reflected in forecasts, i-STAT shall use commercially reasonable efforts to accommodate such increases within reasonable manufacturing capabilities and efficiencies, taking into account other orders and forecasts. If such increases reflects an increase of more than one hundred twenty percent (120%) of the amount of Products (on a Product-by-Product basis) originally reflected in Heska’s binding forecasts, i-STAT shall advise Heska of any additional costs associated with manufacturing such increased number of Products in such timeframe, and if Heska indicates to i-STAT that i-STAT should proceed to manufacture such increased amount of Products, i-STAT shall use reasonable commercial efforts to manufacture such increased number of Products, and Heska shall bear all costs reasonably associated with such manufacturing increases. Such payments shall be payable within thirty (30) days of receipt of i-STAT’s invoice for such charges. 3.6 Purchase Prices. Purchase Prices for the Products are listed on Exhibit 1.29. 3.6.1 Rebates. [***] 12 3.6.2 Pricing Adjustments. At the end of the Initial Term and each Extension Term thereafter, Purchase Prices may be adjusted at i-STAT’s sole discretion for inflationary increases in production costs. Such increase shall be at the rate of increase in the U.S. PPI (Producer Price Index) since the Effective Date of the Agreement for the Initial Term or since the last inflationary adjustment for each Extension Term. 3.6.3 Increased Manufacturing Costs. If i-STAT experiences an increase in Product manufacturing costs that exceed ten percent (10%) for any Product during any Contract Year, i-STAT and Heska shall meet and negotiate in good faith to determine whether an adjustment to the Purchase Price for that Product is appropriate in the circumstances. 3.6.4 Taxes. All Purchase Prices for Product are calculated for delivery as set forth in Section 3.7. The Purchase Prices do not include insurance, freight, customs, duties, taxes, any foreign, federal, state or local taxes that may be applicable to Products including, without limitation, sales, excise, value-added, withholding, and other taxes other than taxes based upon i-STAT’s net income and other similar charges. Customs duties and charges, if any, shall be borne by Heska. Any and all export and import licenses or approvals shall be obtained by Heska at its expense. When i-STAT has the legal obligation to collect such taxes, the appropriate amount shall be added to Heska’s invoice and paid by Heska unless Heska provides i-STAT with a valid tax exemption certificate authorized by the appropriate taxing authority. 3.7 Delivery of Product. 3.7.1 Delivery; Determination of Method of Transportation. Products shall be delivered FCA (Incoterms 2000) i-STAT’s U.S. warehouse or other i-STAT warehouse.

Risk of loss for Products shall pass to Heska, FCA (Incoterms 2000) i-STAT’s warehouse site. 3.7.3 Title. Title shall pass to Heska when Products are transferred to Heska’s designated courier at i-STAT’s warehouse site. 3.8 Payments Due; Credit Limits. All payments due and payable hereunder shall be made by check or wire transfer within thirty (30) days from the date of the invoice. All payments shall be made without set-off or counterclaim and free and clear of and without deduction for any other charges of any kind. The invoiced amount shall be paid by Heska to i-STAT by: (a) wire transfer to the bank listed on Exhibit 3.8 or otherwise 13 specified by i-STAT, or (b) certified bankers check. i-STAT reserves the right to change the payment or credit terms at any time upon ninety (90) days’ prior notice to Heska. Any invoiced amount not received within thirty (30) days of the date the payment was due shall be subject to a service charge of the lesser of one and one-half percent (1.5%) per month or the maximum rate permitted by law. All exchange, interest, banking collection and other charges shall be at Heska’s expense. Decreases in Heska’s credit limit will be based on i-STAT’s evaluation of Heska’s financial performance over the previous six (6) months and/or Heska’s payment history with i-STAT over the past immediate twelve (12) months. If Heska disagrees with any notice of a change in payment terms or decrease in credit limit, Heska may dispute the decision with the President of Abbott’s Point of Care business and discuss options for resolution. The resolution to the disputed decrease in credit limit shall be at the sole discretion of the President of Abbott Point of Care division. If Heska believes the resolution reached by the President of Abbott Point of Care is inequitable, Heska may enter into alternative dispute resolution with i-STAT. Notwithstanding anything in this Agreement or any exhibit attached hereto to the contrary: (y) all costs for Heska and i-STAT associated with such alternative dispute resolution shall be borne solely by Heska, regardless of the decision by the neutral in the alternative dispute resolution process; and (z) such alternative dispute resolution, if requested by Heska for this issue, shall be only for this specific issue, and no other issue shall be added to the process. 3.9 Currency Basis. All prices including Product Prices for Products and payments therefor shall be in U.S. dollars. 3.10 Acceptance of Product. Heska shall not be obligated to accept any Product that does not meet the applicable i-STAT specifications as set forth in the Analyzer’s operators’ manuals, or the Cartridges’ product inserts, if any, as registered in the Territory. i-STAT shall provide Heska with thirty (30) days’ advance notice of a change or issuance of new Analyzer operator manuals or Cartridge product inserts. Heska shall inspect all Products upon delivery in a commercially reasonable manner. Failure by Heska to give notice of defective or damaged Product within the time periods specified in Section 3.11 shall be deemed a waiver of i-STAT’s obligations as stated herein, with respect to such defect or damage only. 3.11 Defective and Improper Delivery; Product Returns. If Heska or a Dealer or End User claims that: (a) any Product shipped directly by i-STAT hereunder was damaged in transit to the End User; (b) incorrect Product was shipped; or (c) that there was a shortage in the shipment, and notice in writing of such damage, incorrect shipment or shortage is provided to i-STAT within thirty (30) days of receipt of the shipment by the End User then, upon receipt of such notice, i-STAT’s sole obligation shall be to either replace any damaged or incorrectly shipped Product, make up any shortfall or refund any Purchase Price paid by Heska, at i-STAT’s option. If any Product is claimed by Heska, a Dealer or End User to be defective and i-STAT is notified in writing of such 14 defect within thirty (30) days of receipt of the Product by the End User or, in the case of a latent defect, i-STAT is notified in writing within fifteen (15) days of discovery of such latent defect within the warranty period stated in Section 7.2, then i-STAT’s sole obligation shall be to either repair of replace any Product found by i-STAT to be defective. If Heska claims a credit pursuant to this Section 3.11, such claim shall be accompanied by the original invoice issued by Heska to the End User or Dealer returning the Product. Upon request by i-STAT, Heska shall deliver to i-STAT, at Heska’s cost, any returned Product with regard to which the credit is claimed. i-STAT solely shall determine in good faith the amount of any credit due Heska, if any, and to the extent any returned Product is defective, reimburse Heska for reasonable freight expenses directly related to delivering said Product to i-STAT. In the event that i-STAT issues a Product recall and requests that Heska return Products to i-STAT as a result of such recall, i- STAT shall reimburse Heska for reasonable freight expenses directly related to such recall. There will be no Product returns accepted except as set forth in this Section 3.11. ARTICLE 4. MARKETING OF PRODUCTS 4.1 Marketing. Heska shall, at its own expense, use commercially reasonable efforts to market and promote the Products in the Territory. Heska’s promotional activities shall include, but shall not be not limited to: (a) including the Products in its appropriate catalogs, promotional mailings and like publications, (b) developing, preparing and placing advertising concerning the Products in appropriate media or through appropriate direct mail; (c) exhibiting the Products at appropriate trade shows and exhibitions, (d) conducting appropriate market research as it deems necessary or desirable; and (e) rendering other services customarily rendered by a distributor of veterinary medical products; provided, that by October 31 of each Contract Year, Heska shall provide i-STAT with a list of all proposed trade shows and exhibitions that it plans to attend in the next Contract Year. Heska may develop printed sales and promotional materials relating to the Products in the local language at its own expense. Heska shall provide such materials, if any, which have not been previously approved to i-STAT for i-STAT’s review and approval, which approval shall not be unreasonably delayed or withheld. i-STAT shall review such materials within fifteen (15) Business Days, and i-STAT’s failure to object to any materials within such fifteen (15) Business Days of sending shall be deemed approval. If i-STAT objects to the material, Heska shall modify such materials accordingly. 4.2 Catalogs, Bulletins. At Heska’s written request, i-STAT shall provide Heska with reasonable quantities of brochures, instructional material, advertising literature and other relevant Technical Documentation regarding the Products, at no charge to Heska. Such documents shall be in the English language, and may be in other languages to the extent already available. Heska, at its own cost, may provide a translation of the 15 documents into the local language. Such translations shall be made available to i-STAT for review and comment before dissemination. 4.3 Follow-up Training. At Heska’s reasonable written request, i-STAT shall provide follow-up training, as mutually agreed by the Parties, at Heska’s facility. i-STAT shall pay for its employees’ salaries and their travel and travel-related expenses, including meals, lodging and other living expenses. For training situations not covered by this Section 4.3, the Parties shall discuss how to equitably share the travel and related expenses. 4.4 Strategy Meetings. Periodically during the Term (but not less than once per Contract Year) while Heska is the exclusive distributor of Products in the Field in the Territory, Heska and i-STAT shall review topics which may include Heska’s marketing and selling strategy, training of End Users, inventory, and other practices with a view toward maximizing End Users’ use of and satisfaction with Products. 4.5 Quality Assurance Audit. Heska agrees that upon a minimum fifteen (15) days notice from i-STAT, representatives of i-STAT, during normal business hours, shall be permitted to visit all locations where Heska maintains inventory of Products to conduct a quality assurance audit of such facilities and/or an on-site surveillance of the inventory storage tracking. i-STAT shall have the right during reasonable business hours, to inspect the books and records of Heska relating to Product complaint documentation. In the event that an audit reveals items that i-STAT determines should be corrected by Heska, i-STAT shall provide, in writing, within thirty (30) days of such audit, a list of such items and any proposed corrective action to be taken by Heska. Heska shall respond within fifteen (15) days of receiving i-STAT’s notification of the corrective action to be taken and an estimated completion date. If the parties disagree as to whether corrective action is necessary, the matter shall be resolved in accordance with the alternative dispute resolution procedures set forth in Section 11.9. 4.6 Sales Personnel. Heska, at its sole cost and expense, shall engage, compensate, supervise, train and maintain such competent, qualified personnel as may be reasonably required to, deliver, promote, market, sell, distribute, provide technical service and support for the Products, and End User complaint handling in the Territory. 4.7 Training For Heska and End Users. i-STAT shall provide Heska personnel such training, at i-STAT’s expense, as Heska may request in writing and that i-STAT, at its sole discretion, deems reasonable. Notwithstanding the above, all expenses incurred by Heska’s personnel in connection with such training, including without limitation, travel and other per diem expenses shall be borne by Heska. Heska, at its own cost, shall provide adequate Product training for its End User’s on the use and storage of the Products. Heska, prior to shipment of Products to an End User, shall provide to each such End User Product storage and use instructions, and shall provide its End Users 16 with commercially reasonable training and support within two (2) months after delivery of the first shipment of Products to an End User. Heska shall use commercially reasonable efforts to ensure that all introductory training is made available to End Users within the first week after receipt of Analyzers and Cartridges. Heska shall, in its discretion, make appropriate use of training materials and Technical Documentation supplied by i- STAT. 4.8 Technical Support. Heska agrees to be responsible as the first point of contact for technical support with the End User. Heska will further provide technical support on the usage of Products by the End Users based upon information supplied by i-STAT, at no cost to i-STAT. The term “Technical Support” shall mean, without limitation, problem resolution, explanation of functionality and collection of incident reports. i-STAT will provide technical service support to Heska as i-STAT deems reasonably necessary, but not to any Dealers appointed by Heska. 4.9 Modified and New Products. Heska agrees to provide timely comprehensive information to its Dealers or End Users, as appropriate, with respect to newly available Products, discontinuance of Products and changes in existing Products, including, but not limited to, performance specification changes and required software upgrades in Analyzers (which may or may not be coupled to specific lots of Cartridges). Heska agrees to use commercially reasonable efforts, which shall depend on the circumstance involved and whether the End User is utilizing Products, to ensure that each End User in the Territory makes any such performance specification changes and software upgrades in a timely manner. 4.10 Counterfeit Products. If Heska is offered the opportunity to purchase or otherwise becomes aware of any counterfeit products similar in look and/or function to Analyzer or Cartridge Products (as listed on Exhibit 1.29) manufactured by an entity other than i-STAT (“Counterfeit Products”), Heska shall promptly notify i-STAT thereof. Heska covenants and agrees not to purchase any Counterfeit Products, and the failure of Heska to comply with the foregoing covenant and agreement shall constitute grounds for immediate termination of this Agreement by written notice to such effect sent by i-STAT. Such termination of this Agreement shall be effective as of the date of receipt of any such notice by Heska. In addition, Heska acknowledges that its purchase of Counterfeit Products will cause i-STAT irreparable harm and that i-STAT shall have the right to equitable and injunctive relief, in addition to money damages, in the case of such action by Heska. i-STAT acknowledges and agrees that Counterfeit Products do not include, and Heska shall be permitted to sell and/or license in the Field, any products that Heska offers to Heska’s End Users that would allow Heska’s End Users to print test results from an Analyzer on standard sized paper and combine such results with test results from other diagnostic products Heska sells in the Field. 17 4.11 Inventory Levels. Heska shall maintain a commercially reasonable supply of Product to meet the demands of End Users, taking into account the order and shipping lead times set forth in this Agreement. 4.12 Warranty Services. Heska shall provide a technical liaison and assistance to End Users for warranty service of the Products, at no cost to i-STAT or the End Users. In addition, at the written request of i-STAT, Heska shall perform certain warranty repairs during the term of the warranty, which shall be billed to and paid by i-STAT at mutually agreed upon labor rates. 4.13 Books and Records. Heska shall maintain books and records in keeping with standard industry practice regarding the performance of its obligations hereunder including monthly Cartridge unit Sales to Dealers and End Users that Heska Sells to directly, aggregated monthly in each country or region, and shall retain such records during the Term and for three (3) years thereafter. Heska shall provide to i-STAT annually within thirty (30) days following the end of each Contract Year, a report that provides Cartridge unit Sales to Dealers and End Users that Heska Sells to directly, aggregated monthly in each country or region, and the calculation of the percentage of Cartridges Sold to customers by country or region, beginning with the first report of Contract Year 2005. Such books and records shall be in accordance with generally accepted accounting principles reflecting each Product’s unit Sales and per country or region in the Territory. Upon thirty (30) days’ prior written notice to Heska (but not more frequently than once in any Contract Year, unless there is a dispute, then as frequently as is necessary), Heska’s books and records relating to the matters described herein shall be open for inspection. To conduct such inspection, i-STAT shall retain, at its own expense, an independent certified public accountant reasonably acceptable to Heska. Such examination shall occur at Heska’s principal place of business during normal business hours for the sole purpose of verifying the accuracy of such calculations. Such independent accountant shall be required to execute a mutually acceptable confidentiality agreement and shall report to i-STAT only the amount of any discrepancy, if any, in the calculations. Such examination rights may be exercised by the Parties only with respect to records for the then-current Contract Year and the immediately prior Contract Year. i-STAT shall bear the cost of such audit, unless the audit reveals an underreporting of unit Sales of greater than one percent (1%) or a value of Ten Thousand US Dollars (US $10,000) (whichever is the greater), in which case Heska shall reimburse i-STAT for its reasonable expenses incurred in connection with such audit. 4.14 Corrupt Practices. Heska shall not use any compensation hereunder as payment to any government official or employee of any country in the Territory for the purpose of influencing such person’s decisions or actions regarding the Products. 18 ARTICLE 5. INTELLECTUAL PROPERTY RIGHTS 5.1 i-STAT Markings. Heska shall not omit or alter patent numbers, trade names or trademarks, numbers or series or any other i-STAT markings affixed on the Products obtained from i-STAT or alter Product labeling. Heska shall, however, be entitled to mark the Products with its trademark or trade name in prominent place, subject to i-STAT’s prior written consent, not to be unreasonably withheld. Heska is not authorized to use the trademark and trade name “i-STAT” or any other trademark or trade name of i-STAT in any manner except to indicate that i-STAT is the manufacturer of the Products and, consistent with the provisions of Section 5.2 and during the Term of this Agreement and only in the Field in the Territory, that Heska is an independent distributor for i-STAT and is selling i-STAT’s Products. Heska shall acquire no rights in the i-STAT trademark and trade name, or any other trademark owned by i-STAT. 5.2 Use of Trademarks and Tradenames. i-STAT hereby authorizes Heska to use, on a nonexclusive basis for the Term, without cost to Heska other than payment for the Products, the trademark “i-STAT” and any other trademarks, service marks or tradenames used by i-STAT to identify the Products (the “Marks”), solely to identify i-STAT as the manufacturer of the Products and for Heska’s distribution of Products and related performance under this Agreement. The Marks and the goodwill associated therewith are and shall remain the exclusive property of i-STAT. Heska shall not: (a) use the Marks as part of any composite mark including any elements not approved in advance in writing by i-STAT; (b) challenge the validity or enforceability of the Marks (unless such restriction is illegal); (c) acquire any proprietary rights in the Marks by reason of any activities under this Agreement or otherwise. All uses of the Marks by Heska and any additional goodwill created thereby shall inure to the exclusive benefit of i-STAT. i-STAT, at all times during the Term on reasonable notice, shall have the right to inspect the materials and services on or in connection with which the Marks are used in order to assure i-STAT that its quality standards relating to the Products and Heska’s servicing and other Mark-pertinent provisions of this Agreement are being observed. If at any time i-STAT shall reasonably object to any use to which the Marks are put, Heska shall promptly cease any such use. 5.3 License to Use Computer Software. All software, on whatever media and in whatever form, i-STAT shall deliver to Heska hereunder (the “Software”) is and shall remain the property of i-STAT and its suppliers and licensors thereof and shall only be used in accordance with the terms of this Agreement and any End User License Agreements (each, a “EULA”) distributed therewith. Software contains copyrighted and proprietary trade secrets of i-STAT (and its suppliers and licensors), and Heska shall keep the Software in confidence. Heska shall not copy, use or disassemble the Software unless agreed by i-STAT. Heska shall have the right to reproduce Software only for: (a) one backup/archival copy; and (b) installation on and use with equipment designated by i-STAT as suitable therefor and for use solely with the Products distributed by Heska. 19 Heska shall reproduce the copyright and other proprietary notices of i-STAT and Third Parties present in the Software delivered to Heska. Heska’s license to use and distribute the Software shall terminate on the earlier of: (w) termination of this Agreement; (x) discontinuance of use of the designated equipment for the Software; (y) discontinuance of payment of periodic license and maintenance fees, if any; or (z) breach by Heska of any of the above given terms; provided, that End Users’ license rights shall continue in accordance with each EULA. All copies of Software with respect to which the license hereunder is terminated shall be returned to i-STAT within thirty (30) days after such termination. Heska shall deliver to each End User a copy of i-STAT’s EULA, which shall inform them that such Software is and shall remain the property of i-STAT and its suppliers and licensors. Copies of the translated materials shall be provided by Heska to i-STAT for inclusion in the technical file before any CE marked Product is distributed in Heska’s territory in the Field. ARTICLE 6. REGULATORY MATTERS 6.1 Regulatory Compliance. Heska shall advise i-STAT promptly of all government regulations outside of the United States affecting the importation, use, Sale, record maintenance and disposal of the Products, and shall be responsible for compliance therewith. Without limiting the foregoing, Heska shall obtain from competent governmental authorities outside the United States such import permits, licenses, exemptions from customs duties and governmental approvals and consents required in connection with the execution and performance of this Agreement. All governmental permits, registrations, licenses, exemptions and consents outside the United States specifically relating to Products shall be sought, where applicable and where possible, in the name of and shall, at the end of the Term, be the exclusive property of i-STAT. Heska shall not take any action which would, or fail to take any action where such failure would, directly or indirectly result in or constitute a violation by Heska of any applicable law, treaty, ruling or regulation in the Territory relating to the Products, including, without limitation, laws and regulations relating to the export, resale and distribution of the Products and laws and regulations requiring the reporting of adverse medical events to government authorities in the Territory. When needed for sales or regulatory compliance purposes, Heska shall provide at Heska’s expense any additional translations of labels, labeling, and instructions consistent with the regulatory requirements of the competent authority in each country of the Territory and shall ensure that all users are provided with such translated materials. 6.2 Compliance with U.S. Regulations. Heska understands and acknowledges that i-STAT is subject to regulation by agencies of the U.S. Government, including but not limited to, the U.S. Department of Treasury which prohibit the sale, export or diversion of products and technology to certain countries (“Prohibited Countries”), which countries, as of the Effective Date, are Iran, Sudan and Cuba. Heska hereby warrants that it shall not Sell, 20 directly or indirectly, any Products to Dealers or End Users which it knows or reasonably should know will resell or export the Product to Third Parties in Prohibited Countries. Furthermore, any and all obligations of i-STAT to provide the Products, as well as any other technical information and assistance, is subject to United States laws and regulations which govern the license and delivery of technology and products abroad by persons subject to the jurisdiction of the United States, including without limitation the Export Administration Act of 1979, as amended, any successor legislation, and the Export Administration Regulations issued by the Department of Commerce, Bureau of Industry and Security. Heska agrees to cooperate with i-STAT in order to maintain compliance with the applicable export regulations. 6.3 Notice of Certain Events; Adverse Event Reporting. Each Party shall promptly notify the other after it becomes aware of any of the following events: alleged infringement of the Trademarks or patents applicable to a Product by any third party; alleged infringement of the trademark, patent or proprietary rights of others in connection with actions taken hereunder; liability claims relating to a Product and any other event that may reasonably be expected to have a material adverse effect upon the sale or distribution of a Product in the Territory. 6.4 Product Changes; Labeling. Heska may affix its label on catalogs and Products being distributed by Heska in the Field in the Territory during the Term; provided, i-STAT shall have been provided with a catalog and a photograph of each Product with Heska’s label affixed in the same manner in which the Products will be distributed and shall have approved such label, such approval not to be unreasonably withheld and such approval not required for Products being sold with the Heska label affixed as of the Effective Date. If i-STAT shall reasonably object to the manner in which such label is affixed, Heska shall promptly cease any such use and change its use to comply with the i-STAT’s requirements. Heska shall bear the cost of packaging and labeling changes requested by Heska and approved by i-STAT. 6.5 Traceability. i-STAT and Heska shall each maintain such traceability records with respect to the Product as shall be necessary to comply with applicable laws and local “Good Manufacturing Practices” regulations. 6.6 Reliability Reporting. Each Party shall promptly report in writing to the other any substantial failure of the Product, material change in the statistically demonstrated reliability of the Product or other material information relevant to the reliability of a Product of which such Party becomes aware. 6.7 Recall or Advisory Actions. If either Party proposes to recall a Product or issue an advisory letter regarding reliability of or defects in a Product, then such Party shall first notify the other in writing or by telecommunication in a timely manner prior to making such recall or issuing such advisory letter. Each Party shall endeavor to reach an 21 Agreement with the other regarding the manner, text and timing of any publicity to be given such matters in time to comply with any applicable regulatory requirements, but such Agreement shall not be a precondition to any action that a Party deems necessary to protect users of a Product or to comply with any applicable governmental orders. In the event i-STAT should request Heska to recall a Product, Heska shall take all appropriate actions to recall such Product. i-STAT shall bear the expenses of any recall requested by it or resulting from defective manufacture, or packaging by i-STAT. Heska shall bear the expenses of any recall resulting from improper storage, handling or delivery by Heska. In cases where the recall is unrelated to any fault of either Party, the expense of the recall shall be borne by the Parties equally. For the purposes of this Agreement, expenses of recall include, without limitation, the expense of notification and destruction or return of the recalled Product, but not the expense or service fees associated with salesmen’s time which shall be borne by Heska. 6.8 Translation of Technical Documents. Consistent with Section 4.2, as required by local regulatory laws or regulations, Heska shall translate Technical Documents into the local language(s) of End Users and shall revise such translation in accordance with the changes to the Technical Documents that may be made from time to time by i-STAT. Such translation shall at a minimum meet all regulatory requirements of the Territory and be of a standard deemed appropriate for veterinary products and comparable with that provided for other products sold into the animal health care market in the Territory. Heska will provide any documents translated into the local language to i-STAT for review and shall revise such translation according to i-STAT’s comments. ARTICLE 7. REPRESENTATIONS AND WARRANTIES 7.1 Product Warranty to End Users. Heska shall pass through to End Users i-STAT’s standard written limited warranty for all Products. Heska shall not alter or expand such warranty; provided, however, that nothing in this Agreement limits Heska’s ability to provide its own warranty on any of the Products to its End Users (an “Extended Warranty”) so long as Heska is responsible for satisfying any obligations under such Extended Warranty. 7.2 Warranty. i-STAT shall extend to Heska and to Heska’s Dealers or End Users standard product warranties, as modified from time to time upon thirty (30) days prior written notice to Heska, the current version of which is attached as Exhibit 7.2; provided, however, that any modification to any such product warranties shall apply only to Products the Sales of which are made after the effective date of such product warranties. 7.3 Heska’s Warranty.

In the event of any Third Party action, the indemnified Party shall have the right to participate in the defense, at its own expense, with counsel of its own choosing. 8.2 Indemnification by Heska. Heska shall indemnify i-STAT against all claims, losses, damages, liabilities and expenses, including reasonable attorneys’ fees and disbursements, incurred by i-STAT arising with respect to the sale, distribution or use of a Product to the extent caused by any action or omission of Heska or its stockholders, directors, officers, employees or agents. Heska shall indemnify, defend and hold i-STAT harmless against all claims, liabilities, costs and expenses (including the reasonable fees of attorneys and other professionals) incurred by, or threatened against, i-STAT in connection with any representation or warranty by Heska (including any Extended Warranty of the Products provided by Heska) or Heska’s personnel inconsistent with: (a) the foregoing limited warranty and disclaimer of i-STAT; or (b) publications of i-STAT concerning the Products. 8.3 Infringement Indemnification by i-STAT. i-STAT shall indemnify Heska against all claims, losses, damages, liabilities and expenses, including reasonable attorneys’ fees and disbursements, incurred by Heska arising with respect to, out of or in connection with any claim that the Products or the Software infringe any copyright, patent, trade 23 secret, trademark, or other proprietary right of any third party; provided that i-STAT is notified promptly in writing of the claim and Heska provides reasonable assistance in the settlement or defense of such claim; provided, that Product or Software are not altered by Heska except as specifically directed by i-STAT. If a Product or Software is held to constitute an infringement and its use as contemplated by this Agreement is enjoined or threatened to be enjoined, i-STAT shall at its option and expense: (a) procure for Heska the right to continue to Sell and distribute the Products or the Software; (b) replace or modify the Products or the Software with a version that is non-infringing; or (c) discontinue manufacture and/or sales of the Product in affected countries. In the event that i-STAT discontinues the manufacture and/or sale of a Product pursuant to this Section 8.3 in any affected country, such discontinuance shall not be considered a breach of this Agreement, and the Parties shall negotiate in good faith an adjustment, if any, to the Base Cartridge Targets set forth in Sections 2.4 and 2.5. If the Parties are unable to agree on an adjustment, if any, to the Base Cartridge Targets as a result of good faith negotiations under the preceding sentence, they will follow the procedures set forth in Section 11.9 to establish an adjustment, if any. 8.4 Limitation of Liability. UNDER NO CIRCUMSTANCES SHALL A PARTY BE RESPONSIBLE TO THE OTHER PARTY FOR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR IN CONNECTION WITH THE SALE, DELIVERY, NONDELIVERY, SERVICING, USE, MAINTENANCE, SUPPORT, CONDITION OR POSSESSION OF PRODUCTS. ARTICLE 9. CONFIDENTIALITY 9.1 Confidentiality. Neither Party shall use for any purpose, other than as contemplated by this Agreement, or divulge to any Third Party, any Confidential Information provided to such Party by the other Party, except as may be required by law or judicial order. 9.2 Public Announcements. Neither Party shall make any public announcement concerning this Agreement, nor make any public statement which includes the name of the other Party or any of its Affiliates, or otherwise use the name of the other Party or any of its Affiliates in any public statement or document, except as may be required by law, including the requirements of the SEC, or judicial order, without the written consent of the other Party, which written consent shall not be withheld unreasonably. 24 ARTICLE 10. TERM AND TERMINATION 10.1 Effective Date and Term. The initial term of this Agreement shall commence as of the Effective Date and expire as of December 31, 2009 (the “Initial Term”), unless sooner terminated as expressly provided in this Article 10 or Section 2.6. THIS AGREEMENT WILL RENEW AUTOMATICALLY FOR ADDITIONAL ONE (1) YEAR TERMS (EACH, AN “EXTENSION TERM”), UNLESS SOONER TERMINATED AS EXPRESSLY PROVIDED IN THIS ARTICLE 10 OR SECTION 2.6. The Initial Term and all Extension Terms are sometimes referred to herein as the “Term.” 10.2 Termination For Cause By Either Party. In addition to the rights of the Parties to terminate this Agreement as provided hereinabove, either Party may terminate this Agreement for cause upon written notice to the other Party in the event the other Party: (a) appoints a receiver, executes an assignment for the benefit of creditors or files or otherwise becomes subject to bankruptcy or insolvency proceedings; or (b) materially breaches this Agreement and fails to cure such breach within sixty (60) days after receipt of written notice of breach from the non-breaching Party, as such cure period may be extended for such additional period as the non-breaching Party reasonably determines that the breaching Party is diligently pursuing a cure of such breach. 10.3 By i-STAT for a Change of Control under Certain Circumstances. If Heska undergoes a Change of Control, Heska or the controlling entity following the Change of Control shall notify i-STAT within thirty (30) days of such Change of Control. Such notice shall inform i-STAT of the identify of the entity involved in the Change of Control with Heska, and of the parent corporation, if any, of the entity involved in the Change of Control with Heska. i-STAT shall have the right to terminate this Agreement within six (6) months of such notice if Heska has a Change of Control to an entity that, in i-STAT’s sole opinion, competes with i-STAT or its Affiliates or, in i-STAT’s reasonable business judgment, would harm i-STAT’s position in, the human blood and/or veterinary diagnostics market; provided, that if Heska believes that i-STAT’s determination is unreasonable, the Parties shall follow the procedure set forth in Section 11.9 to make the determination. 10.4 Effect of Termination. Upon the termination of this Agreement: (a) The Parties shall immediately cease the use of any Confidential Information of the other Party and, in the case of Heska, of the Marks, except as permitted in this Section 10.4. 25 (b) Unless this Agreement is terminated by i-STAT for Heska’s breach or bankruptcy, and subject to i-STAT’s rights as provided in this Section 10.4, (i) i-STAT shall honor all accepted purchase orders providing for delivery of Product within thirty (30) days of the date of termination and for which Heska pays in full prior to shipment, and (ii) Heska may Sell Products on a nonexclusive basis but otherwise on the terms set forth in this Agreement its remaining inventory of Products for a period of up to ninety (90) days following the date of termination. (c) i-STAT shall have the right (but not the obligation), upon prior written notice to Heska given within ten (10) days after termination to purchase from Heska all or any portion of the Products in its inventory at the time of such termination for credit against outstanding invoices, or for cash refund to the extent there are no invoices then outstanding. Any credit or refund due Heska for such Product shall be equal to the Purchase Price of the Product, less any discounts or credits previously received. (d) Heska shall return to i-STAT all promotional and sales training materials provided to Heska by i-STAT under this Agreement. (e) To the extent permitted by law, Heska shall assign to i-STAT and deliver to i-STAT any import permits, health resignations, licenses, exemptions from customs duties and governmental consents of any nature specifically relating to i-STAT Products, which Heska may have or retain directly or indirectly in connection with the Products imported, Sold and/or distributed under this Agreement, which it has not yet assigned or waived, or which have not yet been delivered prior to termination. (f) Heska shall not, in the final six months of any notification of termination (or such actual time after notice and before actual termination, if shorter), undertake any actions intended or designed to cause End Users or Dealers to purchase higher than normal levels of inventory of Products. 10.5 Continuing Obligations. Upon any termination of this Agreement (except termination for cause by Heska due to i-STAT’s breach), at i-STAT’s election and in accordance with i-STAT’s instructions, Heska shall: (a) cooperate in referring End Users to i-STAT or to such other persons as i- STAT may direct for continuing purchase of Products and related services; (b) transfer to i-STAT or its nominees all outstanding maintenance contracts for the Products; and (c) provide i-STAT with a list of each End User who purchased Product through Heska, including records of all Software updates performed. 26 [***] — Certain information on this page have been omitted and filed separately with the Securities and Exchange Commission.

Following termination of this Agreement for any reason, Heska shall have no further obligations to End Users with respect to Software updates and maintenance or technical support.

The following Articles and Sections shall survive termination of the Agreement: Articles 1, 7, 8, 9, 10 and 11 and Sections 3.6, 3.8, 3.9, 3.11, 4.12 and 4.13.

Within forty (40) days after the end of each Contract Year, i-STAT shall provide Heska in writing with i-STAT’s calculation of Heska’s Cartridge Purchases in such Contract Year (the “i-STAT Calculation”).

If i-STAT disagrees with Heska’s calculation and Heska requests, in writing, purchase order level detail for the i-STAT Calculation, i-STAT shall provide such information.

If the exchange of such information does not resolve the dispute, the Parties shall negotiate in good faith to determine the actual Cartridge Purchases in such Contract Year and, if such dispute is not resolved within thirty (30) days, the dispute shall be resolved pursuant to Section 11.9. 11.3 [***]. 11.3.1 [***]. 11.3.2 [***]. 11.4 Binding Effect/Assignment. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their successors and assigns.

Any failure by one of the Parties to assert its rights for or upon any breach of this Agreement shall not be deemed to be a waiver of such rights, nor shall such waiver be implied from the acceptance of any payment. 11.6 Relationship of the Parties. Nothing in this Agreement or any other document or agreement between the Parties shall constitute or be deemed to constitute a partnership or joint venture between the Parties. The relationship between Heska and i-STAT shall be that of buyer and seller. No officer, agent or employee of one Party shall under any 29 circumstances be considered the agent, employee or representative of the other Party. Neither Party shall have the right to enter into any contracts or binding commitments in the name of or on behalf of the other Party in any respect whatsoever. 11.7 Force Majeure.

[***] EXHIBIT 11.3F xv EXHIBIT 11.9 ALTERNATIVE DISPUTE RESOLUTION The parties recognize that from time to time a dispute may arise relating to either party’s rights or obligations under this Agreement. The parties agree that any such dispute shall be resolved by the Alternative Dispute Resolution (“ADR”) provisions set forth in this Exhibit, the result of which shall be binding upon the parties. To begin the ADR process, a party first must send written notice to the other party in accordance with the terms of the Agreement describing the dispute and requesting attempted resolution by good faith negotiations between their respective president or principal executive officer(s) (or their designees) of the affected subsidiaries, divisions, or business units within twenty-eight (28) days after such notice is received (all references to “days” in this ADR provision are to calendar days). If the matter has not been resolved within twenty-eight (28) days of the notice of dispute, or if the parties fail to meet within such twenty-eight (28) days, either party may initiate an ADR proceeding as provided herein. The parties shall have the right to be represented by counsel in such a proceeding. 1. To begin an ADR proceeding, a party shall provide written notice to the other party in accordance with the terms of the Agreement of the issues to be resolved by ADR. Within fourteen (14) days after its receipt of such notice, the other party may, by written notice to the party initiating the ADR, add additional issues to be resolved within the same ADR. 2. Within twenty-one (21) days following receipt of the original ADR notice, the parties shall select a mutually acceptable neutral to preside in the resolution of any disputes in this ADR proceeding. If the parties are unable to agree on a mutually acceptable neutral within such period, either party may request the President of the CPR Institute for Dispute Resolution (“CPR”), 366 Madison Avenue, 14th Floor, New York, New York 10017, to select a neutral pursuant to the following procedures: (a) The CPR shall submit to the parties a list of not less than five (5) candidates within fourteen (14) days after receipt of the request, along with a Curriculum Vitae for each candidate. No candidate shall be an employee, director, shareholder or Affiliate of either party or any of their subsidiaries or affiliates. (b) Such list shall include a statement of disclosure by each candidate of any circumstances likely to affect his or her impartiality. (c) Each party shall number the candidates in order of preference (with the number one (1) signifying the greatest preference) and shall deliver the list to the CPR within seven (7) days following receipt of the list of candidates. If a party believes a conflict of interest exists regarding any of the candidates, that party shall provide a xvi written explanation of the conflict to the CPR along with its list showing its order of preference for the candidates. Any party failing to return a list of preferences on time shall be deemed to have no order of preference. (d) If the parties collectively have identified fewer than three (3) candidates deemed to have conflicts, the CPR immediately shall designate as the neutral the candidate for whom the parties collectively have indicated the greatest preference. If a tie should result between two candidates, the CPR may designate either candidate. If the parties collectively have identified three (3) or more candidates deemed to have conflicts, the CPR shall review the explanations regarding conflicts and, in its sole discretion, may either (i) immediately designate as the neutral the candidate for whom the parties collectively have indicated the greatest preference, or (ii) issue a new list of not less than five (5) candidates, in which case the procedures set forth in subparagraphs 2(a) - 2(d) shall be repeated. 3. No earlier than twenty-eight (28) days or later than fifty-six (56) days after selection, the neutral shall hold a hearing to resolve each of the issues identified by the parties. The ADR proceeding shall take place at a location agreed upon by the parties. If the parties cannot agree, the neutral shall designate a location other than the principal place of business of either party or any of their subsidiaries or Affiliates. 4. At least seven (7) days prior to the hearing, each party shall submit the following to the other party and the neutral: (a) a copy of all exhibits on which such party intends to rely in any oral or written presentation to the neutral; (b) a list of any witnesses such party intends to call at the hearing, and a short summary of the anticipated testimony of each witness; (c) a proposed ruling on each issue to be resolved, together with a request for a specific damage award or other remedy for each issue. The proposed rulings and remedies shall not contain any recitation of the facts or any legal arguments and shall not exceed one (1) page per issue. The parties agree that neither side shall seek as part of its remedy any punitive damages. (d) a brief in support of such party’s proposed rulings and remedies, provided that the brief shall not exceed twenty (20) pages. This page limitation shall apply regardless of the number of issues raised in the ADR proceeding. Except as expressly set forth in subparagraphs 4(a) - 4(d), no discovery shall be required or permitted by any means, including depositions, interrogatories, requests for admissions, or production of documents. 5. The hearing shall be conducted on two (2) consecutive days and shall be governed by the following rules: xvii (a) Each party shall be entitled to five (5) hours of hearing time to present its case. The neutral shall determine whether each party has had the five (5) hours to which it is entitled. (b) Each party shall be entitled, but not required, to make an opening statement, to present regular and rebuttal testimony, documents or other evidence, to cross-examine witnesses, and to make a closing argument. Cross-examination of witnesses shall occur immediately after their direct testimony, and cross-examination time shall be charged against the party conducting the cross-examination. (c) The party initiating the ADR shall begin the hearing and, if it chooses to make an opening statement, shall address not only issues it raised but also any issues raised by the responding party. The responding party, if it chooses to make an opening statement, also shall address all issues raised in the ADR. Thereafter, the presentation of regular and rebuttal testimony and documents, other evidence, and closing arguments shall proceed in the same sequence. (d) Except when testifying, witnesses shall be excluded from the hearing until closing arguments. (e) Settlement negotiations, including any statements made therein, shall not be admissible under any circumstances. Affidavits prepared for purposes of the ADR hearing also shall not be admissible. As to all other matters, the neutral shall have sole discretion regarding the admissibility of any evidence. 6. Within seven (7) days following completion of the hearing, each party may submit to the other party and the neutral a post-hearing brief in support of its proposed rulings and remedies, provided that such brief shall not contain or discuss any new evidence and shall not exceed ten (10) pages. This page limitation shall apply regardless of the number of issues raised in the ADR proceeding. 7. The neutral shall rule on each disputed issue within fourteen (14) days following completion of the hearing. Such ruling shall adopt in its entirety the proposed ruling and remedy of one of the parties on each disputed issue but may adopt one party’s proposed rulings and remedies on some issues and the other party’s proposed rulings and remedies on other issues. The neutral shall not issue any written opinion or otherwise explain the basis of the ruling. 8. The neutral shall be paid a reasonable fee plus expenses. These fees and expenses, along with the reasonable legal fees and expenses of the prevailing party (including all expert witness fees and expenses), the fees and expenses of a court reporter, and any expenses for a hearing room, shall be paid as follows: (a) If the neutral rules in favor of one party on all disputed issues in the ADR, the losing party shall pay 100% of such fees and expenses. xviii (b) If the neutral rules in favor of one party on some issues and the other party on other issues, the neutral shall issue with the rulings a written determination as to how such fees and expenses shall be allocated between the parties. The neutral shall allocate fees and expenses in a way that bears a reasonable relationship to the outcome of the ADR, with the party prevailing on more issues, or on issues of greater value or gravity, recovering a relatively larger share of its legal fees and expenses. 9. The rulings of the neutral and the allocation of fees and expenses shall be binding, non-reviewable, and non-appealable, and may be entered as a final judgment in any court having jurisdiction. 10. Except as provided in paragraph 9 or as required by law, the existence of the dispute, any settlement negotiations, the ADR hearing, any submissions (including exhibits, testimony, proposed rulings, and briefs), and the rulings shall be deemed Confidential Information. The neutral shall have the authority to impose sanctions for unauthorized disclosure of Confidential Information. 11. All ADR hearings shall be conducted in the English language. xix [***] — Certain information in this exhibit have been omitted and filed separately with the Securities and Exchange Commission.

Should suit be brought to recover on this Note, or should the same be placed in the hands of an attorney for collection, Maker promises to pay all reasonable attorneys’ fees and 1 costs incurred in connection therewith. Failure of Holder to exercise any option hereunder shall not constitute a waiver of the right to exercise the same in the event of any subsequent default, or in the event of continuance of any existing default. Maker waives demand, diligence, presentment for payment, protest and notice of demand, protest, nonpayment and exercise of any option hereunder. Maker agrees that the granting without notice of any extension or extensions of time for payment of any sum or sums due hereunder, or for the performance of any covenant, condition or agreement hereof shall in no way release or discharge the liability of Maker hereof.

This is covered under Section 12(a) and (b). As a License for the [***] Product has not been obtained as of June 15, 2008, Diamond would begin to make Interim Reimbursement payments equal to [***] per month beginning on July 15, 2008 and ending on December 15, 2009 for a total of [***], such monthly payments calculated as one half of [***] Interim [***] Spending divided by 18. On January 1, 2010, Diamond would make the Final Payment to Distributor of [***], calculated as one half of [***] less the total amount of the Interim Reimbursement ([***]). In this example, Distributor collects [***] ([***] + [***]) or half of its original investment in the failed research project.

The Special Account shall be maintained for the Lender by any financial institution acceptable to the Lender. Any interest earned on amounts deposited in the Special Account shall be credited to the Special Account. Amounts on deposit in the Special Account may be applied by the Lender at any time or from time to time to such Borrower’s Obligation of Reimbursement or any other Obligations, in the Lender’s sole discretion, and shall not be subject to withdrawal by any Borrower so long as the Lender maintains a security interest therein.

The obligations of each Borrower arising under Section 2.18 shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement, under all circumstances whatsoever, including (without limitation) the following circumstances: (a) any lack of validity or enforceability of any Letter of Credit or any other agreement or instrument relating to any Letter of Credit (collectively the “Related Documents”); (b) any amendment or waiver of or any consent to departure from all or any of the Related Documents; (c) the existence of any claim, setoff, defense or other right which any Borrower may have at any time, against any beneficiary or any transferee of any Letter of Credit (or any persons or entities for whom any such beneficiary or any such transferee 26 may be acting), or other person or entity, whether in connection with this Agreement, the transactions contemplated herein or in the Related Documents or any unrelated transactions; (d) any statement or any other document presented under any Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect whatsoever; (e) payment by or on behalf of the Lender under any Letter of Credit against presentation of a draft or certificate which does not strictly comply with the terms of such Letter of Credit; or (f) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

Section 3.2 Notification of Account Debtors and Other Obligors. The Lender may during any Default Period notify any account debtor or other person obligated to pay the amount due that such right to payment has been assigned or transferred to the Lender for security and shall be paid directly to the Lender. Each Borrower will join in giving such notice if the Lender so requests. At any time after any Borrower or the Lender gives such notice to an account debtor or other obligor, the Lender may, but need not, in the Lender’s name or in any Borrower’s name, (a) demand, sue for, collect or receive any money or property at any time payable or receivable on account of, or securing, any such right to payment, or grant any extension to, make any compromise or settlement with or otherwise agree to waive, modify, amend or change the obligations (including collateral obligations) of any such account debtor or other obligor; and (b) as each Borrower’s agent and attorney-in-fact, notify the United States Postal Service to change the address for delivery of such Borrower’s mail to any address designated by the Lender, otherwise intercept such Borrower’s mail, and receive, open and dispose of such Borrower’s mail, applying all Collateral as permitted under this Agreement and holding all other mail for such Borrower’s account or forwarding such mail to such Borrower’s last known address. Section 3.3 Assignment of Insurance. As additional security for the payment and performance of the Obligations, each Borrower hereby assigns to the Lender any and all monies (including, without limitation, proceeds of insurance and refunds of unearned premiums) due or to become due under, and all other rights of such Borrower with respect to, any and all policies of insurance now or at any time hereafter covering the Collateral, to the extent such rights may be assigned in accordance with such policies, or any evidence thereof or any business records or 27 valuable papers pertaining thereto, and such Borrower hereby directs the issuer of any such policy to pay all such monies directly to the Lender. At any time, after and during the continuance of an Event of Default, the Lender may (but need not), in the Lender’s name or in any Borrower’s name, execute and deliver proof of claim, receive all such monies, endorse checks and other instruments representing payment of such monies, and adjust, litigate, compromise or release any claim against the issuer of any such policy. Section 3.4 Occupancy (a) Each Borrower hereby irrevocably grants to the Lender the right to take exclusive possession of the Premises at any time during a Default Period.

(c) The Lender’s right to hold the Premises shall cease and terminate upon the earlier of (i) payment in full and discharge of all Obligations and termination of the Commitment, and (ii) final sale or disposition of all goods constituting Collateral and delivery of all such goods to purchasers. (d) The Lender shall not be obligated to pay or account for any rent or other compensation for the possession, occupancy or use of any of the Premises; provided, however, that if the Lender does pay or account for any rent or other compensation for the possession, occupancy or use of any of the Premises, the Borrowers shall reimburse the Lender promptly for the full amount thereof. In addition, the Borrowers will pay, or reimburse the Lender for, all taxes, fees, duties, imposts, charges and expenses at any time incurred by or imposed upon the Lender by reason of the execution, delivery, existence, recordation, performance or enforcement of this Agreement or the provisions of this Section 3.4. Section 3.5 License. Each Borrower hereby grants to the Lender a non-exclusive, worldwide and royalty-free license to use or otherwise exploit all trademarks, franchises, trade names, copyrights and patents of such Borrower for the purpose of selling, leasing or otherwise disposing of any or all Collateral during any Default Period. Notwithstanding the foregoing, such grant shall not constitute an assignment of any Intellectual Property License to the extent granting such a license is prohibited by or would constitute a default under any such Intellectual Property License (but only to the extent such prohibition is enforceable under applicable law). Section 3.6 Financing Statement. The Borrowers authorize the Lender to file from time to time where permitted by law, such financing statements against collateral described as ‘all personal property’ or describing specific items of collateral including commercial tort claims as the Lender deems necessary or useful to perfect the Security Interest.

(“United”), a customer of Diamond, filed a lawsuit in Wisconsin against Diamond and Heska alleging various claims, including breach of contract and breach of warranty, and demanding compensatory and punitive damages. On October 20, 2005, Diamond and Heska filed a motion to dismiss certain claims against Diamond and all claims against Heska, as well as an answer to United’s claims, affirmative defenses and counterclaims on behalf of Diamond. While Diamond and Heska intend to pursue the matter vigorously and believe they are entitled to damages from United and that United is not entitled to damages from Heska or Diamond, there can be no assurance the ultimate resolution of this case will reflect Heska’s and Diamond’s current beliefs. Schedule 5.10 to Third Amended and Restated Credit and Security Agreement Plans Borrower now maintains or has maintained the following employee pension benefit plans as defined in ERISA, 3(2), 29 U.S.C. 1002(2): 1. The Diamond Animal Health, Inc. Pension Plan for Collective Bargaining Unit Employees. This Defined Benefit Pension Plan is currently frozen. No new participants may enter the plan nor are any contribution liabilities accruing. The plan has a funding liability of $235,974 for Termination purposes, calculated as of May 1, 1998; this liability is a result of the difference between the GATT rates used to calculate contributions and the PBGC rates required to be used by a terminating plan. Upon termination, participants must receive the larger of the accrued benefit calculated using GATT rates and using PBGC rates. Since the PBGC rates have been consistently lower than the GATT rates, the Pension Plan has a funding liability on termination. The Plan can remain frozen until such time as the PBGC rates match the GATT rates or Diamond chooses to contribute funds to make up the termination funding liability. The termination funding liability varies from year to year based upon fluctuations in interest and mortality rates. The Plan does not have a funding liability under the provisions of Internal Revenue Code 412, and there are no reportable events. 2. The Diamond Animal Health, Inc. Saving Plan (the “Savings Plan”). The Savings Plan is a profit sharing/401(k) plan. It was merged into the Heska Corporation 401(k) Plan (the “Heska Plan”) effective January 1, 1998. Diamond Animal Health, Inc. is the wholly owned subsidiary of its parent, Heska Corporation. Diamond Animal Health, Inc. was acquired by Heska Corporation in April, 1996. At the time of the acquisition, both Heska and Diamond sponsored 401(k) plans. In accordance with the provisions of Treas. Reg. 1.401(k)-1(d)(3), Heska Corporation determined that it would be in the best interests of both Heska and Diamond to merge the Savings Plan into the Heska Plan. Both plans have been submitted to the Internal Revenue Service for a Determination that: (1) the Savings Plan was a tax-qualified plan as of the effective date of the merger; and (2) the Heska Plan remains a tax-qualified plan on and after the merger date. 3. The Heska Corporation 401(k) Plan (the “Heska Plan”) The Heska Plan is a defined contribution plan that was established under the provisions of Section 401(a) of the Internal Revenue Code (“IRC”), which includes a qualified deferred arrangement as defined in Section 401(k) of the IRC, for the benefit of eligible employees of Heska Corporation. The Heska Plan is subject to the provisions of ERISA. Benefits under the plan are not guaranteed by the Pension Benefit Guaranty Corporation. On July 1, 2003, the Heska Plan changed custodians and record keepers from Principal Life Insurance Company to Putnam Fiduciary Trust Company.
