OVERVIEW AND CERTAIN RECENT DEVELOPMENTS Chiron is a biotechnology company that participates in three global healthcare businesses: biopharmaceuticals, vaccines and blood testing. The Company is applying a broad and integrated scientific approach to the development of innovative products for preventing and treating cancer, infectious diseases and cardiovascular disease. The Company's products include Proleukin-Registered Trademark- (aldesleukin), a recombinant form of interleukin-2, which the Company markets as a treatment for metastatic renal cell carcinoma and metastatic melanoma. The Company manufactures recombinant human platelet-derived growth factor, the active ingredient in Regranex-Registered Trademark- (becaplermin) Gel, which is marketed by Ortho-McNeil Pharmaceutical, Inc. ("Ortho-McNeil"), a Johnson & Johnson ("J&J") company, as a treatment for diabetic foot ulcers. Chiron also manufactures Betaseron-Registered Trademark- (interferon beta-1b) for Berlex Laboratories, Inc. ("Berlex") and its parent company, Schering AG, which is marketed by Berlex and Schering AG as a treatment for multiple sclerosis. In addition, the Company sells a line of traditional pediatric and adult vaccines. The Company has an interest in a number of other products through collaborations and joint businesses, including a joint immunodiagnostics business with Ortho-Clinical Diagnostics, Inc., a J&J company, which sells a full line of tests required to screen blood for hepatitis viruses and retroviruses, and a separate collaboration with Gen-Probe Incorporated, which is developing products using nucleic acid testing technology to screen blood in blood banks and plasma in the plasma industry for infection by viruses. Chiron has a strong commitment to research as an essential component of its product development effort. The Company focuses its research and development activities primarily on areas in which it has particular strengths, including cancer, infectious diseases and cardiovascular diseases. An important part of the Company's research and development effort is undertaken through collaborations with third parties who are able to contribute significant enabling technologies and other resources to the development and commercialization of the product, including in some cases, marketing and sales expertise. In January 1995, the Company established an alliance with Novartis AG ("Novartis"), a life sciences company headquartered in Basel, Switzerland. As of February 1, 2000, Novartis held shares representing approximately 44% of the outstanding common stock of the Company. For more on the Novartis alliance, see "Relationship With Novartis" below. The Company was incorporated in California in 1981 and was merged into a Delaware corporation in November 1986. The Company's principal executive offices are located at 4560 Horton Street, Emeryville, California 94608, and its telephone number at that address is (510) 655-8730. 1 PRODUCTS BIOPHARMACEUTICALS The Company's leading therapeutic product is Proleukin-Registered Trademark- (aldesleukin), a recombinant form of interleukin-2 ("IL-2"). IL-2 is a protein produced naturally in the body in very small quantities. IL-2 stimulates the immune system to increase the production and function of immune cells, including lymphocytes (white blood cells) that help fight certain cancers and may help fight viral infections. While the precise anti-tumor mechanism of Proleukin-Registered Trademark- is unknown, research has demonstrated that it induces the proliferation of immune cells, including natural killer and cytotoxic T cells that can recognize and mobilize against tumor-specific antigens on the surface of malignant cells. Proleukin-Registered Trademark- is marketed by the Company directly or through distributors in the United States and over 40 other countries in North America, Europe and South America for the treatment of metastatic renal cell carcinoma (a type of kidney cancer) and, in the United States and Canada, for the treatment of metastatic melanoma (a form of skin cancer). Chiron manufactures recombinant human platelet-derived growth factor (rhPDGF-BB), the active ingredient in Regranex-Registered Trademark- (becaplermin) Gel, developed with Ortho-McNeil through a collaboration in growth factor research that began in 1984. Ortho-McNeil markets Regranex-Registered Trademark- in the United States as a treatment for diabetic foot ulcers. Regranex-Registered Trademark- works by enhancing the body's natural wound healing processes. It stimulates the migration of cells to the site of the ulcer, encouraging the patient's body to grow new tissue that helps heal these open wounds. Regranex-Registered Trademark- was the first product demonstrated to assist in the healing of diabetic foot ulcers. Regranex-Registered Trademark- also has been approved for marketing in Canada, Europe, Asia and other regions of the world. Chiron manufactures Betaseron-Registered Trademark- (interferon beta-1b) for Berlex and its parent company, Schering AG of Germany. Berlex markets Betaseron-Registered Trademark- primarily in the United States and Canada to treat patients with relapsing remitting multiple sclerosis and in Canada to treat patients with secondary progressive multiple sclerosis. Multiple sclerosis is an autoimmune disease in which the patient's immune system attacks and destroys an element of the patient's own central nervous system. The Company also receives royalties from the sale of a similar product in Europe, Betaferon-Registered Trademark-, which is manufactured by Boehringer Ingelheim and marketed by Schering AG for the treatment of patients with relapsing remitting or secondary progressive multiple sclerosis. In April 1999, the FDA approved DepoCyt-Registered Trademark- for treatment of lymphomatous meningitis, subject to a post-approval (phase IV) clinical study. DepoCyt-Registered Trademark- consists of cytarabine (a generic chemotherapy product) encapsulated in a novel delivery system, called Depofoam-Registered Trademark-. The Company developed DepoCyt-Registered Trademark- in the United States in a collaboration with SkyePharma, Inc. (formerly DepoTech Corporation) ("SkyePharma"). SkyePharma manufactures DepoCyt-Registered Trademark- and the Company markets it in the United States. In October 1999, SkyePharma discovered two lots that did not meet manufacturing specifications and, as a result, vials from these lots were recalled. Sale of this product is on hold while the Company and SkyePharma work with the Food and Drug Administration ("FDA") to resolve various manufacturing issues. Sales of Proleukin-Registered Trademark- (IL-2) accounted for approximately 15%, 13% and 12% of consolidated total revenues in 1999, 1998 and 1997, respectively. Sales of Betaseron-Registered Trademark- (interferon beta-1b), which include product sales to Berlex and Schering AG and royalties earned on Schering AG's European sales of Betaferon-Registered Trademark- (interferon beta-1b), accounted for approximately 13% (9% product sales and 4% royalties), 13% (9% product sales and 4% royalties) and 14% (10% product sales and 4% royalties) of total revenues in 1999, 1998 and 1997, respectively. No other single therapeutic product or class of therapeutic products accounted for 10% or more of consolidated total revenues of the Company in any of the last three fiscal years. VACCINES Through its subsidiary Chiron S.p.A., based in Siena, Italy, the Company manufactures and markets in Italy vaccines for diphtheria, tetanus, pertussis, meningococcus, haemophilus influenzae, flu, measles, 2 mumps, rubella, hepatitis A and an oral polio vaccine and, under license, markets a vaccine for typhoid fever. Through its subsidiary Chiron Behring GmbH & Co ("Chiron Behring"), based in Marburg, Germany, the Company manufactures and markets in Germany vaccines for diphtheria, tetanus, pertussis, flu, rabies, tick-borne encephalitis, tuberculosis, cholera and an oral polio vaccine and, under distribution agreements with other manufacturers, markets vaccines for hepatitis A, measles, mumps, rubella, typhoid fever, pneumococcal disease, haemophilus influenzae type b, an inactivated polio vaccine, an acellular pertussis vaccine and a recombinant vaccine for hepatitis B. Certain of these vaccines are marketed in other European countries and in the Middle East, the Far East, Africa and South America, and to international health agencies such as the World Health Organization. The Company markets its rabies vaccine in the United States. The Company also has developed an adjuvanted flu vaccine, which currently is marketed in Italy. The Company is seeking approval to market the adjuvanted flu vaccine elsewhere in Europe through the European mutual recognition procedure. See "Government Regulation" below. The Company has developed a genetically engineered acellular vaccine for pertussis (whooping cough), which currently is marketed in Italy both as a monovalent vaccine and in combination with diphtheria and tetanus ("DTaP"). The Company has received approval from the European Medicines Evaluation Agency to market its DTaP vaccine for infants and toddlers in Europe. The Company has developed a conjugate vaccine (Menjugate-TM-) against meningococcal C disease. Invasive infection with the bacteria N. meningitidis can lead to meningitis and septicemia (blood poisoning). Meningococcal meningitis, which can be caused by multiple serogroups (A, B, C, Y and others), is associated with a high mortality rate. In March 2000, the Medicines Control Agency approved Menjugate-TM- for sale in the United Kingdom. The National Health Service in the United Kingdom has accepted the Company's tender to supply Menjugate-TM- in 2000. In addition to revenues from the sale of the vaccine products described above, the Company receives royalties from the sale of vaccines against hepatitis B developed, manufactured and marketed by Merck & Co., Inc. ("Merck") and SmithKline Beecham Biologics ("SmithKline"), using technology developed by Chiron. Merck's hepatitis B vaccine was the first vaccine produced using genetic engineering licensed by the FDA for human use. No single vaccines product or class of vaccines products accounted for 10% or more of consolidated total revenues of the Company in any of the last three fiscal years. BLOOD TESTING Chiron's blood testing business comprises two separate collaborations: a joint business with Ortho-Clinical Diagnostics, Inc. ("Ortho"), an affiliate of J&J, and an alliance with Gen-Probe Incorporated ("Gen-Probe"). Chiron's joint business with Ortho was formed in 1989, based largely on the screening, using immunodiagnostic technology, of blood in blood banks and other similar settings for the potential presence of human immunodeficiency virus ("HIV") and hepatitis viruses. The joint business sells a full line of tests required for hepatitis viruses and retroviruses and provides supplemental tests and microplate-based instrument systems to automate test performance and data collection. Chiron performs certain research and manufactures viral antigens and supplemental hepatitis tests, while Ortho manufactures and sells assays and instrument systems. Chiron and Ortho share equally in the pretax operating earnings generated by the joint business. The joint business holds the immunodiagnostic rights to Chiron's hepatitis and retrovirus technology and receives royalties from the sale of hepatitis C virus ("HCV") and HIV tests by Abbott Laboratories ("Abbott") and from sales of HCV tests by Bio-Rad Laboratories, Inc. and certain other licensees. Chiron's collaboration with Gen-Probe is focused on developing and commercializing products using nucleic acid testing technology to screen blood in blood banks and plasma in the plasma industry for infection by viruses. Compared to immunodiagnostic testing, testing directly for the presence of viral 3 nucleic acid improves the sensitivity of detection and enables infection to be detected earlier following infection. Under the terms of the collaboration agreement, Gen-Probe performs certain product development and assay and instrument manufacturing functions while Chiron and Gen-Probe jointly participate in new assay and instrument research and development. Chiron will sell the collaboration's products. Gen-Probe will receive a fixed percentage of Chiron's sales revenues. The commercial market for nucleic acid testing products in the blood banking and plasma industries is developing very rapidly as regulatory agencies worldwide began in 1999 to develop policies or mandates for future implementation of nucleic acid testing in blood banks and plasma centers. The Chiron/Gen-Probe collaboration's first product, a combined test for HIV-1 and HCV using a semi-automated instrument system, is being used to screen blood under an Investigational New Drug ("IND") clinical study in the United States. See "Research and Development--Blood Testing." No single blood testing product or class of blood testing products accounted for 10% or more of consolidated total revenues of the Company in any of the last three fiscal years. RESEARCH AND DEVELOPMENT Chiron has a strong commitment to research as an essential component of its product development effort. Technologies developed in collaborations with third parties, as well as technologies licensed from outside parties, also are sources of potential products. BIOPHARMACEUTICALS Chiron has utilized a variety of approaches for developing biopharmaceutical products. In 1999, the Company narrowed its R&D efforts to focus on those platforms which management believes are more likely to generate new product candidates. Going forward, Chiron expects to concentrate on two primary product engines: recombinant proteins and small molecules, supported by biological discovery. The Company is seeking a corporate partner for its gene therapy program. GENE/BIOLOGICAL DISCOVERY. Genomics and other technologies are used to discover new genes and to determine their role and the role of the encoded proteins in a target disease. With this information, the Company then identifies and develops potential products, including therapeutics for treatment of disease and vaccines for prevention of disease. RECOMBINANT PROTEINS. Proteins produced naturally by the human body play a variety of roles in controlling disease. When administered as therapeutic agents, certain proteins or specific antibodies against them can enhance the patient's natural ability to fight disease. However, traditional methods of isolating or producing proteins can be cost-prohibitive, particularly in the quantities needed for pharmaceutical use. Through genetic engineering, certain proteins which might not otherwise be available can be produced in relatively large quantities at reasonable cost. The Company and its collaborators have a number of recombinant proteins in clinical development. Proleukin-Registered Trademark- (IL-2), already approved for marketing as a treatment for certain forms of kidney and skin cancer, is being clinically evaluated for other indications, including treatment of patients with HIV infection, treatment of acute myelogenous leukemia and as a treatment for non-Hodgkin's lymphoma in conjunction with an approved antibody therapeutic. Fibroblast Growth Factor ("FGF"), a growth factor which can stimulate the formation of new blood vessels, is in clinical studies for use as a treatment for coronary artery disease and peripheral artery disease. Tissue Factor Pathway Inhibitor ("TFPI"), a coagulation inhibitor, is being developed in collaboration with G.D. Searle & Co. ("Searle"), a subsidiary of the Monsanto Company. The Company and Searle are conducting clinical studies on the use of TFPI as a treatment for patients with severe sepsis. Insulin-Like Growth Factor ("IGF"), a growth factor which can stimulate the formulation of cartilage, is in clinical development for the treatment of osteoarthritis. Chiron and Cephalon, Inc. ("Cephalon") have discontinued their joint collaboration to develop Myotrophin-Registered Trademark-(mecasermin) (IGF-I) as a treatment for amyotrophic lateral sclerosis (also known as ALS or Lou Gehrig's disease). In 1997, an FDA advisory committee found that there was not sufficient evidence of efficacy of 4 Myotrophin-Registered Trademark- as a treatment for ALS to warrant approval. In May 1998, Chiron and Cephalon received a letter from the FDA indicating that Myotrophin-Registered Trademark- is potentially approvable, contingent upon additional evidence of efficacy and safety. While the new drug application ("NDA") for Myotrophin-Registered Trademark- remains pending at the FDA, Chiron and Cephalon have no present plans to submit additional data in response to the FDA's request. Each company has borne its own costs of this program since July 1998. In September 1998, Chiron and Cephalon withdrew their application to market Myotrophin-Registered Trademark- (IGF-I) in Europe. SMALL MOLECULE DRUG DISCOVERY. Chiron's small molecule drug discovery program combines multiple disciplines, including combinatorial and computational chemistry, robotic screening and selection and molecular biology, to screen, identify and refine compounds which may be used as drugs for treating medical conditions or disorders. In addition to drug discovery against specific disease targets of interest to the Company, from time to time the Company enters into collaboration agreements with third parties under which the Company utilizes its proprietary technologies to identify drug candidates directed at specific disease targets of interest to the partner. Certain compounds which may be of interest have been identified and are being further optimized and tested prior to moving into clinical development. GENE THERAPY. Traditional recombinant protein therapeutics are produced outside the patient's body and administered to the patient, typically through injection. Gene therapy enables the patient's own body to produce a desired protein by inserting the gene for that protein into the patient's cells. Currently there are no gene therapy products on the market. Many studies suggest that the technology is promising but considerable further study is required to determine whether this technology can be safely and effectively utilized to treat disease. An example of a potential application of gene therapy currently in clinical development at the Company is Factor VIII. Factor VIII is a protein that causes blood to clot. Hemophiliacs, as a result of a hereditary defect, are born with faulty copies of the gene that produces Factor VIII. Through gene therapy, it may be possible to insert into a hemophiliac's cells the normal Factor VIII gene, so that the patient's own cells can produce the blood clotting protein. A key component of any gene therapy treatment will be the mechanism for "inserting" the gene into the patient's cells. The Company is developing several gene transfer systems, including retroviral and other viral vectors. VACCINES PROPHYLACTIC VACCINES. Chiron is developing a new generation of vaccines for the prevention of disease utilizing genetic engineering and other techniques of modern biotechnology, including vaccines based on recombinant antigens. The Company currently is conducting preclinical studies on vaccines for a number of targets. The Company also is developing novel adjuvants. Adjuvants are compounds that amplify the immune response generated by vaccine antigens. One of Chiron's adjuvants, MF-59, is a component of Chiron's new flu vaccine, which currently is marketed in Italy. In addition, Chiron is conducting preclinical investigations of alternative delivery systems for vaccines that may be used in lieu of injection, such as nasally or orally delivered vaccines. THERAPEUTIC VACCINES. The Company is investigating the potential use of vaccines for therapeutic purposes, in which antigens are used to stimulate an immune response against established infections and cancer. The Company's therapeutic vaccine for treatment of chronic hepatitis B infection is in clinical development. BLOOD TESTING Ortho is developing a range of hepatitis and retrovirus assays for IN-VITRO clinical diagnostics use on its immunodiagnostics instrument system. The Chiron/Gen-Probe collaboration has two instrument systems in development, both of which are designed to be used with the HIV-1 and HCV nucleic acid assay to test human plasma. The semi-automated system is currently operating under IND in the United States while the fully automated Procleix-TM-Tigris-Registered Trademark- system is under development. Chiron and Gen-Probe are widening the menu from 5 HIV-1/HCV to include other transfusion transmitted agents, and Gen-Probe is continuing development of the fully automated Procleix-TM-Tigris-Registered Trademark- system. RESEARCH REVENUES AND EXPENSES Collaborative arrangements with third parties are also a source of revenue for the Company. In general, collaboration revenues include fees for research services as they are performed or completed and milestone payments upon attainment of specified benchmarks. Novartis and the Company have entered into an agreement under which Novartis has agreed to provide research funding for certain projects. The funded projects currently consist of certain adult and pediatric vaccines, Insulin-Like Growth Factor-I, Factor VIII and HSV-tk. The agreement provides that, through December 2000, at Chiron's request, Novartis will fund up to 100% of the development costs incurred between January 1, 1995 and December 31, 1999 on the funded projects. The amount of funding that Novartis is obligated to provide is subject to an aggregate limit of $265.0 million. As of December 31, 1999, the Company had used $252.9 million of the funding. In exchange for providing this funding, Novartis has certain co-promotion rights for certain vaccines as well as an interest in certain royalties on sales of certain products resulting from the funded research. Research and development expense for the years ended December 31, 1999, 1998 and 1997 for Company-sponsored research, including payments to collaboration partners, was $303.4 million, $286.6 million and $256.6 million, respectively. Of that, $49.7 million, $61.9 million and $79.5 million in 1999, 1998 and 1997, respectively, was reimbursed by third parties. COMMERCIALIZATION Technologies arising out of the Company's research and development efforts are commercialized in a variety of ways. Certain products are marketed and distributed by the Company, either directly or through distributors. See "Distribution" below. Other technologies are developed by the Company in collaboration with third parties, and under the collaboration agreement, marketing rights may be allocated to the Company or to the collaborator or shared by both parties. In the event marketing rights are allocated to the collaborator, the Company generally retains the right to manufacture and supply key raw materials to the collaborator. Still other technologies are licensed by the Company to third parties, with the licensee assuming responsibility for further development and the Company receiving royalties on sales of the resulting product. Agreements under which the Company currently derives revenues for technologies licensed to third parties include an agreement with Bayer relating to, among other things, use of the Company's HCV and HIV technologies for IN VITRO diagnostics; an agreement with F. Hoffman La-Roche Limited and Hoffman La-Roche, Inc. ("Roche"), relating to polymerase chain reaction ("PCR") technology; an agreement with Merck relating to hepatitis B vaccines, an agreement with SmithKline relating to recombinant vaccine manufacturing technology and an agreement with Novo Nordisk A/S relating to technology used in the manufacture of recombinant human insulin. In September 1999, Chiron granted a license to Abbott under its HCV patents for use in nucleic acid amplification in clinical diagnostics, excluding blood screening. DISTRIBUTION To remain competitive in an intensely competitive environment, Chiron maintains several specialized marketing and sales forces that concentrate on individual classes of customers. The Company's vaccine marketing organization is based in Siena, Italy and Marburg, Germany. Direct sales efforts are focused on pediatricians and general practitioners. Products are also sold to the public sector through tenders and to private sector pharmacies through wholesalers and distributors. Chiron's biopharmaceuticals marketing, sales and distribution organization for the U.S. is based in Emeryville, California and for Europe is headquartered in Amsterdam, The Netherlands. Sales efforts are 6 focused on specialist physicians, principally oncologists, who are based in hospitals and large clinics. In general, products are sold to wholesalers, distributors and hospital pharmacies. RAW MATERIALS Raw materials and other supplies used in the manufacture of the Company's products (both commercial and investigational) generally are available from multiple commercial sources. Certain processes, however, use materials that are available from sole sources or that are in short supply or that are difficult for the supplier to produce and certify in accordance with the Company's specifications. The Company's biopharmaceutical products are biologics. From time to time, concerns are raised with respect to potential contamination of biological materials that are supplied to the Company for use in various production processes. These concerns can further tighten market conditions for materials that may be in short supply or available from limited sources. Moreover, regulatory approvals to market the Company's products may be conditioned upon obtaining certain materials from specified sources. The Company's ability to substitute material from an alternate source may be subject to delay pending regulatory approval of such alternate source. Although the Company monitors the ability of certain suppliers to meet the Company's needs and the market conditions for these materials, there is a risk that material shortages could impact production. PATENTS Patents are very important to the business of the Company. Chiron has a policy of seeking patents on inventions arising from its extensive research and development activities. The time and expense required to develop and obtain regulatory approval to market human healthcare products is significant. Without the protection of patents or trade secrets, competitors may be able to use the Company's inventions to manufacture and market competing products without being required to undertake the lengthy and expensive development efforts made by Chiron. Chiron has a substantial number of granted patents and pending patent applications in the United States and other important markets, and a number of patents and patent applications owned by third parties have been licensed to Chiron. There can be no assurance that patents and patent applications owned or licensed to Chiron will provide substantial protection. Important legal questions remain to be resolved as to the extent and scope of available patent protection for biotechnology products and processes in the United States and other important markets. It is not known how many of the Company's pending patent applications will be granted, nor the effective coverage of those that will be granted. In the United States and other important markets, the issuance of a patent is not conclusive as to its validity or the enforceable scope of its claims. The Company has engaged in significant litigation to determine the scope and validity of certain of its patents and expects to continue to do so in the future. Even if the Company is successful in obtaining and defending patents, there can be no assurance that these patents will provide substantial protection. Third parties may be able to design around the patents and develop competitive products that do not use the inventions covered by the patents. Many countries, including certain countries in Europe, have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties (for example, the third party's product is needed to meet a threat to public health or safety in that country, or the patent owner has failed to "work" the invention in that country, or the third party has patented improvements), and most countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may be limited to monetary relief and may be unable to enjoin infringement, which could materially diminish the value of the patent. Furthermore, most countries do not provide discovery so the Company may not be able to meet its burden of proving infringement; nor can it be guaranteed that the Company will even become aware of infringement of its patents. To a lesser extent, trade secrets and confidential information are important to Chiron's commercial success. Although the Company seeks to protect trade secrets and confidential information, there can be no assurance that others will not obtain access to such information or develop the same or similar 7 information independently, or that third parties will not obtain patent protection that precludes Chiron from using its trade secrets or confidential information. Chiron is aware that third parties, including competitors, educational institutions and governmental organizations, have patents and patent applications in the United States and other significant markets that may be useful or necessary for the manufacture, use or sale of certain of the Company's products (commercial and investigational). There may be other such patents and patent applications of which the Company is not currently aware. It is likely that third parties will obtain other such patents in the future. Certain of these patents may be sufficiently broad to prevent or delay Chiron from practicing necessary technology, including manufacturing or marketing products important to the Company's current and future business. The scope, validity and enforceability of such patents, if granted, the extent to which Chiron may wish or need to obtain licenses to such patents and the cost and availability of such licenses cannot be accurately predicted. If Chiron does not obtain such licenses, products may be withdrawn from the market or delays could be encountered in market introduction while an attempt is made to design around such patents. Alternatively, Chiron could find that the development, manufacture or sale of such products is foreclosed. Chiron could also incur substantial costs in challenging the validity and scope of such patents. TRADEMARKS Proleukin-Registered Trademark- is a registered trademark of the Company and its subsidiaries. ELVS-TM-, Polioral-TM-, Triacelluvax-TM- and Procleix-TM- are trademarks of the Company and its subsidiaries. DepoCyt-TM- is a trademark owned by Chiron and SkyPharma. The following registered trademarks are owned by the indicated companies: Betaseron-Registered Trademark- and Betaferon-Registered Trademark- (Schering AG), Myotrophin-Registered Trademark- (Cephalon), Regranex-Registered Trademark- (J&J), Apligraf-Registered Trademark- (Novartis), Dermagraf-Registered Trademark- (Advanced Tissue Sciences, Inc.), Copaxone-Registered Trademark- (Teva Pharmaceutical Industries, Ltd.), Avonex-Registered Trademark- (Biogen, Inc.), Aredia-Registered Trademark- (Novartis), Amplicor-Registered Trademark- (Roche) and Novantrone-Registered Trademark-(Immunex). Tigris-Registered Trademark- is a trademark owned by Gen-Probe. SEASONALITY Sales of certain of the Company's vaccine products, in particular flu vaccine, are seasonal, with higher sales in the third and fourth quarters of the year. The Company receives royalties on sales of PCR products by Roche. Under the terms of the Company's agreement with Roche, royalties are payable after Roche's annual net sales of PCR products exceed $200.0 million. This $200.0 million threshold resets at the beginning of each year. Accordingly, the Company does not expect to receive any royalties on Roche's PCR sales until the last half of each year. Roche's royalty obligation will expire upon the earlier of December 31, 2000 or when Chiron recognizes royalties with an aggregate net present value of $30.0 million as of the date of the agreement. As of December 31, 1999, Chiron had recognized royalties with a net present value of $13.2 million. MAJOR CUSTOMERS The Company has a strategic alliance with Novartis and in connection therewith has entered into a series of arrangements with Novartis. See "Relationship With Novartis" below. These arrangements contributed 8%, 12% and 21% of total revenues in 1999, 1998 and 1997, respectively. The Company has a joint immunodiagnostics business with Ortho. See "Products--Blood Testing" above. The Ortho joint business, together with certain other arrangements with J&J and its affiliates, contributed 14%, 18% and 24% of total revenues in 1999, 1998 and 1997, respectively. The Company has a supply agreement with Berlex and its parent company, Schering AG of Germany. Revenues recognized under this agreement contributed 13%, 13% and 14% to total revenues in 1999, 1998 and 1997, respectively. 8 COMPETITION Chiron operates in a highly competitive environment, and the competition is expected to increase. Competitors include large pharmaceutical, chemical and blood testing companies, as well as biotechnology companies. Some of these competitors, particularly large pharmaceutical and blood testing companies, have greater resources than the Company. The technologies applied by the Company and its competitors are rapidly evolving, and new developments frequently result in price competition and product obsolescence. Substantial consolidation is underway in the global healthcare industry and is expected to produce greater efficiencies and even more intense competition. To compete effectively, Chiron invests heavily in research and development, maintains specialized sales forces that concentrate on individual classes of customers and spends significant amounts on advertising, promotion and selling. Important biotechnology research is performed in universities and nonprofit research organizations. These entities are becoming more active in seeking patent protection and licensing revenues for their discoveries. The competition among large pharmaceutical companies and smaller biotechnology companies to acquire technologies from these entities also is intensifying. While Chiron actively collaborates with such entities in research, and has and will continue to license their technologies for further development, these institutions also compete with Chiron to recruit scientific personnel and to establish proprietary positions in technology. BIOPHARMACEUTICALS Proleukin-Registered Trademark- competes with alpha interferon sold by Schering Plough Corporation and by Roche as a treatment for metastatic kidney cancer and metastatic melanoma, although many patients are treated with both products. The Company estimates that Proleukin-Registered Trademark- has approximately a 50% market share for metastatic kidney cancer and a 25% market share for metastatic melanoma. The principal method of competition is product performance. Several other companies are developing immune-system-based therapies for cancers and infectious diseases, including Roche, Genentech, Inc., Amgen, Inc., Immunex and Immune Response/Agouron. Regranex-Registered Trademark- was the first product approved by the FDA for treatment of diabetic foot ulcers. Products that it indirectly competes with include Dermagraft-Registered Trademark-, a product from Advanced Tissue Sciences & Smith and Nephew, and Apligraf-Registered Trademark-, a product from Novartis which has been approved by the FDA for treatment of venous leg ulcers and is in clinical trials for treatment of diabetic foot ulcers. Betaseron-Registered Trademark-, as a treatment for multiple sclerosis, competes with Avonex-Registered Trademark-, a recombinant interferon beta sold by Biogen, Inc., and with Copaxone-Registered Trademark- from Teva Pharmaceuticals. In March 2000, the FDA issued an approvable letter for Novantrone-Registered Trademark- from Immunex for the treatment of secondary progressive multiple sclerosis. In Europe, Schering AG's product, Betaferon-Registered Trademark-, faces competition from Ares Serono, which sells another form of beta interferon that is used for, among other purposes, treatment of multiple sclerosis. Other companies have treatments for multiple sclerosis in clinical development. VACCINES Four large companies hold the greatest share of the worldwide vaccine market: Merck, SmithKline, Wyeth Lederle Vaccines & Pediatrics, a division of American Home Products Corporation ("Lederle"), and Aventis Pasteur (formerly Pasteur Merieux Connaught). Aventis Pasteur separately has a strategic alliance with Merck. All four of these companies, as well as other biotechnology companies, have substantial research and development programs. The Company estimates that it has approximately a 31% and 35% market share in Germany and Italy, respectively, and an aggregate market share of approximately 11% outside of the United States, Europe and Japan. The principal methods of competition in vaccines are price and introduction of new products, including vaccines against diseases for which no vaccine was 9 previously available as well as new combination vaccines that combine existing vaccines for several diseases into a single product. Combination vaccines frequently are favored by public health authorities, medical practitioners and patients, particularly in the case of pediatric vaccines, because they eliminate the need for multiple injections and may increase overall compliance with recommended vaccination schedules. As new combination vaccines are introduced, older combinations and single products often become obsolete. The Company may be limited in its ability to develop and market certain combination vaccines if one of the vaccines which would otherwise be included in the combination is covered by valid and enforceable patent or other proprietary rights held by third parties. BLOOD TESTING Chiron is the sole manufacturer of HCV antigens for use in immunodiagnostic assays of the Chiron-Ortho joint businesses and also manufactures HCV antigens for Abbott's immunodiagnostic assays. In the immunoassay blood testing market, the Chiron-Ortho joint business competes with Abbott. The joint business anticipates increased competitive pressures from Abbott with the introduction of the Abbott PRISM-Registered Trademark- instrument system. The joint business is also developing immunodiagnostic instruments and assays to detect hepatitis, retrovirus and other agents in clinical diagnostic applications. Many other companies, including Roche, Abbott and Bayer Corporation, have substantial positions in the market segment. Currently, there are no approved, nucleic acid-based tests for commercial use in blood testing, other than the Chiron/Gen-Probe test for HIV-1/HCV, which has received approval in France. The Chiron/Gen-Probe test for HIV/HCV currently is being used under an IND in the United States, and it is estimated that approximately 70% of the U.S. blood supply is tested with this product. The Chiron/Gen-Probe products are expected to compete primarily with PCR-based products supplied by Roche or developed in-house by customers (homebrew) and, in some markets, the HCV antigen test under development by the Chiron-Ortho joint business. The commercial market for nucleic acid testing products in the blood banking and plasma industries is developing very rapidly as regulatory agencies began in 1999 to develop policies and mandates that require this new technology to be implemented as an additional measure to improve blood safety. GOVERNMENT REGULATION Regulation by governmental authorities in the United States and other important markets is a significant factor in the manufacture and sale of the Company's products and in its research and development activities. BIOPHARMACEUTICALS AND VACCINES. In the United States, Chiron's therapeutic and vaccine products (both commercial and investigational) are regulated primarily under federal law and are subject to rigorous FDA approval procedures. No product can be marketed in the United States until an appropriate application is approved by the FDA. The approval procedures are applied on a product-by-product basis and typically require, among other things, an extensive three-phase human clinical testing program. In phase 1, studies are conducted with a relatively small number of subjects to assess the safety of the product. In phase 2, the product is evaluated in a larger group of subjects to begin to assess efficacy. Phase 3 studies are conducted in the target population with a number of subjects that is large enough to provide sufficient data to establish statistically the safety and efficacy of the product. FDA approval of a product is limited to treatment for specified medical conditions or disorders, and further studies would be required to market the product for other indications. All facilities used to manufacture, fill, test and distribute biologic products are required to be inspected and approved by the FDA. If any change is made in manufacturing facilities or processes after FDA approval is obtained, additional regulatory review and possibly additional clinical studies may be required. 10 Licensing procedures in Europe are comparable to those in the United States. In 1995, the European Union ("EU") established a centralized procedure for licensing of products derived from the use of high technology/biotechnology processes. This procedure leads to the grant of a single license for the entire EU. Effective January 1, 1998, the EU has also adopted a decentralized procedure under which a license granted in one member state is mutually recognized by the other member states, leading to a grant of licenses in member states recognizing the original license. This procedure is expected to replace independent national licensing of products in the EU. In addition, each product must receive individual country pricing approvals before it can be marketed in that country. BLOOD TESTING. Blood testing products, whether based upon immunodiagnostics or nucleic acid testing technologies, may only be used pursuant to the terms of approval of specific license applications in which the product's safety and effectiveness must be demonstrated based upon well controlled studies. Upon approval of the license application, the product may be marketed for the specific indications of use, which were identified in the approval. Facilities, processes and operations used for the manufacture, testing, storage and distribution of Chiron's blood testing products in the U.S. are subject to FDA approval and periodic inspection. For blood testing and, in particular, biopharmaceutical products, the time and expense needed to complete the required clinical studies, prepare and submit the required applications and supporting documentation and respond to inquiries generated by regulatory review can far exceed the time and expense of the research initially required to create the product. These factors largely determine the speed with which a successful research program is translated into a marketed product. ENVIRONMENT Expenses for compliance with environmental laws have not had and are not expected to have a material impact upon the Company's capital expenditures, earnings or competitive position. EMPLOYEES On December 31, 1999, Chiron and its subsidiaries had 3,110 employees. RELATIONSHIP WITH NOVARTIS As noted above, the Company has an alliance with Novartis. Novartis is a life sciences company headquartered in Basel, Switzerland which was formed as a result of the December 1996 merger between Ciba-Geigy Limited ("Ciba") and Sandoz Limited. Through a series of transactions that became effective in January 1995, Ciba acquired shares of the Company's common stock which, when combined with shares already held by Ciba, represented 49.9% of the then-outstanding common stock of the Company. As a result of dilution stemming primarily from the issuance of common stock under the Company's employee stock option and stock purchase plans and in connection with certain acquisitions, as of February 1, 2000, Novartis held shares representing approximately 44% of the Company's outstanding common stock. In connection with these transactions, Chiron and Novartis entered into a series of agreements which provide, among other things and subject to certain conditions and exceptions, that Novartis will not increase its ownership interest in the Company above 55% before January 5, 2001 and thereafter will not increase its ownership above 55% unless it acquires all of the outstanding capital stock of the Company in a "buy-out" transaction; that Novartis may not propose or consummate a "buy-out transaction" before January 5, 2001; that Novartis may exceed these standstill amounts and increase its ownership interest up to 79.9% if the transaction is approved by a majority of the independent members of the Company's Board of Directors; that Novartis has the right to nominate three members to Chiron's twelve member Board of Directors; that Novartis will provide certain funding to the Company for research services (see "Research and Development--Research Revenues and Expenses" above) and will guarantee certain bank lines of credit on behalf of the Company; that Chiron may require Novartis to purchase shares of the Company's 11 common stock directly from the Company at fair market value, up to a maximum subscription amount (initially $500 million, subject to adjustment); that Novartis has an option to purchase newly issued shares of the Company's common stock directly from the Company at fair market value, subject to the standstill restrictions described above; and that Chiron and Novartis will cooperate in research, development, manufacturing and marketing of biotechnology products on an arm's-length basis while remaining independent to pursue other opportunities. ITEM 2. PROPERTIES EMERYVILLE CAMPUS. Chiron's principal executive offices are located in Emeryville, California. The campus consists of 26 buildings, of which 14 are leased and 12 are owned. The leased facilities include the research and development facility in Emeryville, which is under an operating lease arrangement. The Emeryville facilities include research and development, manufacturing and administrative facilities for the Company's biopharmaceutical, vaccine and blood testing businesses. OTHER R&D AND MANUFACTURING FACILITIES. The Company also owns a manufacturing facility in Vacaville, California used principally in connection with the Company's biopharmaceutical and vaccine businesses. This facility has available capacity due to lower than expected demand for certain of the Company's products and improved production yields from other facilities. As a result, the Company has entered into contract manufacturing agreements to utilize this available capacity (see Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" below). In December 1999, the Company sold its Amsterdam facility and is leasing back office and warehouse space for some operational and administrative activities. The Company has research and development, manufacturing and administrative facilities in Siena, Italy and Marburg, Germany and manufacturing facilities in Rosia, Italy relating to its vaccine operations. The Siena and Rosia facilities are owned and the Marburg facility is leased. The Company leases research and development facilities in San Diego, California in connection with its gene therapy activities. The Company owns research and development, manufacturing and administrative facilities in Claremont, California. The facilities were used principally in connection with the Company's former ophthalmic products business, which was sold to Bausch & Lomb in December 1997. Bausch & Lomb occupies a significant portion of the facilities under a three-year lease which expires in December 2000. A portion of the Claremont campus was sold in July 1999, with the remaining portion being currently marketed for sale. The Company leases a number of other facilities in North America, Europe, Asia and Australia, primarily for sales and service offices. The Company believes that its facilities are in good operating condition and are adequate for its current needs. The Company continually evaluates future requirements for its facilities. ITEM 3. LEGAL PROCEEDINGS FEDERAL EXPRESS On September 3, 1999, Federal Express Corporation ("Federal Express") filed suit in the Supreme Court of the State of New York, County of Orange against Perseptive Biosystems, Inc., Perkin-Elmer Corporation, PE Biosystems Group, and PE Corporation (together, the "PE Defendants") and Chiron. The matter was removed to the United States District Court for the Southern District of New York on motion by Chiron. The Federal Express complaint relates to a fire that allegedly destroyed a Federal Express aircraft and the majority of its cargo in September 1996. Federal Express claims breach of contract, negligence and product liability with regard to equipment owned and shipped by Chiron and designed, manufactured, packaged and prepared for shipping by the PE Defendants and seeks damages, 12 interest, costs and fees. Federal Express alleges that improper packing and shipping procedures proximately caused destruction of the plane. The National Transportation Safety Board, an agency of the federal government investigated the circumstances surrounding the incident and in 1999, issued a letter of no determination as to the cause of the fire. It is not known when nor on what basis this litigation will be concluded. CONNAUGHT LABORATORIES, LIMITED Chiron was involved in litigation in Italy and The Netherlands with Connaught Laboratories, Limited ("Connaught") relating to TriAcelluvax-TM- and the Company's diphtheria/tetanus/acellular pertussis vaccine. Chiron S.p.A. manufactures and sells TriAcelluvax-TM- in Italy. Connaught alleges that TriAcelluvax-TM- infringes the Italian counterpart of its European Patent 0 527 753 (the "'753 patent"). The '753 patent contains claims which relate to the pertactin protein of BORDETELLA PERTUSSIS. In June 1997, Chiron S.p.A. filed an action against Connaught in the Tribunale di Milano, Italy, challenging the validity of the Italian counterpart of the '753 patent. On February 25, 1998, Chiron filed suit against Connaught in Italy seeking a declaration of invalidity of Connaught's European Patent 0 322 115 (the "'115 patent"). The '115 patent contains claims allegedly relating to pertussis toxin mutant. In December 1997, Chiron filed an action in the District Court of The Hague, The Netherlands, against Connaught to revoke the Dutch counterpart of the '115 patent on grounds of invalidity. Connaught filed a motion to stay proceedings which was denied in November 1998. In January 2000, all of these disputes were settled by agreement of the parties. F. HOFFMAN LA-ROCHE A.G. Chiron is involved in certain litigation in the United States, The Netherlands, Japan, Germany and other countries with F. Hoffman-LaRoche AG and several of its affiliated companies concerning infringement and/or validity of certain patents related to HCV technology. In January 1998, Chiron initiated an action against F. Hoffman-LaRoche, Ltd., several of its affiliated companies (collectively, "Roche") and Daniel Bradley in the United States District Court for the Northern District of California. The Company asserts that Roche's manufacture and sale of Amplicor-Registered Trademark- HCV Test and Amplicor-Registered Trademark- HCV Monitor Test infringes Chiron's U.S. Patent Nos. 5,712,088 (the "'088 patent"), 5,714,596 (the "'596 patent") and 5,863,719 (the "'719 patent") The action also asserts that Bradley breached a 1990 settlement agreement with Chiron, that Roche wrongfully induced this breach, and that Bradley committed slander of title with respect to Chiron's HCV technology. The action seeks damages, injunctive relief and a declaratory judgment that Chiron is the sole and exclusive owner of its HCV technology. Roche filed a counterclaim requesting a declaratory judgment of non-infringement and invalidity and also alleging infringement of U.S. Patent No. 5,580,718 (the "'718 patent"), owned by Hoffman-LaRoche, Inc., which allegedly relates to nucleic acid-based assays for the detection of HCV. The counterclaim of infringement seeks damages and injunctive relief. Chiron is defending on the basis of invalidity and non-infringement of the '718 patent and seeks a declaration of invalidity of U.S. Patent No. 5,527,669 (the "'669 patent"), a related patent also owned by Hoffman-LaRoche. The parties' cross-motions for summary judgment on Roche's license based defenses were resolved in Chiron's favor by a Court order dated June 23, 1999. The order, which is subject to appeal, holds that Roche has neither express nor implied license rights to Chiron's HCV technology. The Court found that foreign and domestic rights were assigned by Bradley to Chiron under the 1990 settlement, that Bradley's earlier litigation against Chiron was RES JUDICATA as to foreign rights, and that Bradley's assignment of such rights to Roche breached his settlement agreement with Chiron. In October 1999, Roche filed counterclaims against Chiron which challenge the validity and enforceability of the patents in suit. Roche also seeks to recover 13 treble damages and an injunction against Chiron for alleged breaches of state and federal antitrust statutes relating to Chiron's HCV licensing practices. Discovery is ongoing. In April 1998, Chiron filed suit against Nippon Roche K.K. in the Tokyo District Court in Japan for infringement of Japanese patent number 2,656,995 (the "'995 patent"), relating to HCV nucleic acid technology. The suit seeks injunctive relief preventing the sale of Roche AG's Amplicor-Registered Trademark- HCV Test and Amplicor-Registered Trademark- HCV Monitor Test by Nippon Roche and damages. Roche has filed a counterclaim for invalidity. Roche has also challenged the validity of the '995 patent in the Japanese Patent Office. In February 1998, Chiron filed an action in The District Court of The Hague, The Netherlands against F. Hoffman-LaRoche AG, several of its affiliated companies (collectively, "Roche AG"), and one of Roche AG's Dutch customers asserting Roche AG's infringement of the Company's European Patent 0 318 216 (the "'216 patent") relating to HCV nucleic acid technology. Chiron sought a cross-border injunction with effect in a number of European countries, prohibiting the sale of Roche AG's Amplicor-Registered Trademark-HCV Test and Amplicor-Registered Trademark- HCV Monitor Test. Roche AG has asserted certain defenses and counterclaims in this matter. Following a trial in October 1998, the Court declined to exercise jurisdiction outside The Netherlands and, therefore, dismissed certain defendants from the case. For procedural reasons, the Court limited its consideration to the Amplicor-Registered Trademark- HCV Monitor Test. Also, the Court requested expert advice from the Het International Jurisch Instituut regarding interpretation under U.S. law of certain contractual issues raised as an affirmative defense by Roche AG. Those issues relate to Roche AG's 1991 purchase of certain Cetus Corporation assets. The expert's report, which was submitted in January 2000 and tended to support Roche's interpretation of those contractual issues, will be the subject of further briefing to the Court in the spring of 2000. In December 1998, the Company filed a parallel, new action before the Dutch Court concerning the Amplicor-Registered Trademark- HCV Test. In a separate proceeding, Roche AG and Chiron are appealing the European Patent Office's Opposition Division's decision upholding the '216 patent in amended form. In January 1997, Chiron, together with Ortho-Clinical Diagnostics, Inc. (formerly known as "Ortho Diagnostics Systems, Inc."), filed suit against F. Hoffman-LaRoche AG ("Roche Germany") in the Regional Court, 4th Civil Division, Dusseldorf, Germany, for infringement of immunoassay technology under the '216 patent. The suit seeks damages and injunctive relief preventing further manufacture or sale in Germany of infringing HCV immunoassay kits. Roche Germany asserted certain claims and defenses in this matter. In April 1999, following a trial, the Court issued a decision granting Chiron's application and entered an injunction. Roche has appealed the decision. Chiron also filed a suit against Roche in Dusseldorf, Germany, for infringement of Chiron's European Patent 0 181 150 relating to HIV probes technology. The suit seeks injunctive relief and damages. Trial of this matter took place in February 2000 and a judgment is expected in May 2000. A suit filed in October 1998 by Roche AG against Chiron and Ortho is pending in the Federal Court of Australia, New South Wales District Registry, seeking revocation of Australian patent number 624105, relating to HCV technology. Discovery is ongoing. In May 1999, Chiron and Gen-Probe, Incorporated ("Gen-Probe") initiated action in the Tribunal of Milan, Italy, against Roche AG and several of its European affiliates (together, "Roche"). The lawsuit seeks a cross-border declaration that Gen-Probe's Transcription Mediated Amplification System ("TMA"), which is used in Chiron/Gen-Probe blood screening kits, does not infringe Roche's European Patent 0 505 012 (the "'012 patent"), which relates to PCR technology. The plaintiffs also seek an assessment of the '012 patent and a declaration of nullity of the Italian counterpart of the '012 patent. ORTHO-CLINICAL DIAGNOSTICS, INC. On February 17, 1998, Chiron filed a lawsuit against Ortho-Clinical Diagnostics, Inc. ("Ortho") in the United States District Court for the Northern District of California. The suit sought to compel arbitration of certain issues relating to the conduct of the parties' joint business. Chiron's motion to compel 14 arbitration was granted by the Court in December 1998. Ortho appealed that order to the Ninth Circuit Court of Appeals and oral argument occurred in February 2000. Thereafter, Ortho refused Chiron's demand to arbitrate in accordance with the District Court's order. On March 31, 1999, Chiron filed a second petition in the United States District Court for the Northern District of California to compel arbitration. On November 1, 1999, the Court entered judgment in Chiron's favor, ordering Ortho to submit the underlying issues to arbitration. It is not known when nor on what basis this matter will be concluded. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS No matters were brought to a vote of Chiron's stockholders in the quarter ended December 31, 1999.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OVERVIEW Chiron is a biotechnology company that participates in three global healthcare businesses: biopharmaceuticals, vaccines and blood testing. The biopharmaceuticals segment consists of products and services related to therapeutics, with an emphasis on cancer, infectious diseases and cardiovascular diseases as well as the development and acquisition of technologies related to recombinant proteins, small molecules and genomics. The vaccines segment consists principally of adult and pediatric vaccines sold primarily in Germany and Italy, as well as in other international markets. The blood testing segment consists of Chiron's one-half interest in the pretax operating earnings of its joint business with Ortho-Clinical Diagnostics, Inc. ("Ortho"), a Johnson & Johnson company, and an alliance with Gen-Probe Incorporated ("Gen-Probe"). Chiron's joint business with Ortho sells a line of immunodiagnostic tests, other than nucleic acid tests, required to screen blood for hepatitis viruses and retroviruses, and provides supplemental tests and microplate-based instrument systems to automate test performance and data 17 collection. Chiron's alliance with Gen-Probe is focused on developing and selling nucleic acid testing ("NAT") products using transcription-mediated amplification ("TMA") technology to screen blood and plasma for infection by viruses. On December 29, 1997, Chiron completed the sale of its ophthalmics business ("Chiron Vision") to Bausch & Lomb Incorporated ("B&L"), and on November 30, 1998, Chiron completed the sale of its IN VITRO diagnostics business ("Chiron Diagnostics") to Bayer Corporation ("Bayer"). The Company's Consolidated Statements of Operations reflect the after-tax results of Chiron Vision and Chiron Diagnostics as discontinued operations for all periods presented. On March 31, 1998, in an acquisition accounted for under the purchase method of accounting, Chiron acquired the remaining 51% interest in Chiron Behring GmbH & Co ("Chiron Behring") from Hoechst AG. Beginning in the second quarter of 1998, the results of Chiron Behring were consolidated with those of the Company. RESULTS OF OPERATIONS REVENUES BIOPHARMACEUTICAL PRODUCT SALES Product sales from the biopharmaceuticals segment were $187.6 million, $201.9 million and $150.6 million in 1999, 1998 and 1997, respectively. In 1999, 1998 and 1997, product sales consisted principally of Proleukin-Registered Trademark- (aldesleukin, interleukin-2), Betaseron-Registered Trademark- (interferon beta-1b) and PDGF (recombinant human platelet-derived growth factor -rhPDGF-BB). PROLEUKIN-REGISTERED TRADEMARK- Chiron sells Proleukin-Registered Trademark- directly in the U.S. and certain international markets. Sales of Proleukin-Registered Trademark- were $111.8 million, $93.2 million and $70.5 million in 1999, 1998 and 1997, respectively. The overall increase in sales from year-to-year was due to (i) continued volume growth in existing indications; (ii) higher prices; and (iii) in 1998, the geographic expansion into various countries and the expanded use of Proleukin-Registered Trademark- for the new indication of metastatic melanoma. The Company continues to pursue additional indications, including human immunodeficiency virus ("HIV"). The Company also anticipates further geographic expansion of Proleukin-Registered Trademark- into additional countries. BETASERON-REGISTERED TRADEMARK- Chiron manufactures Betaseron-Registered Trademark- for Berlex Laboratories, Inc. ("Berlex") and its parent company Schering AG of Germany. Chiron earns a payment for Betaseron-Registered Trademark- upon shipment to Berlex and Schering AG and a subsequent additional payment upon sales by Berlex and Schering AG. Accordingly, Chiron's revenues from Betaseron-Registered Trademark- tend to fluctuate based upon the inventory management practices of Berlex and Schering AG. In October 1998, the contractual rate upon which Chiron recognizes revenues decreased by 2.5% of Berlex's sales of Betaseron-Registered Trademark-. In addition, in July 1997, the terms of payment changed whereby the initial payment received upon shipment decreased and the additional payment due upon sales to patients increased equivalently. The revised payment terms resulted in a timing difference whereby Chiron recognized a decrease in initial revenues in 1997 when compared with 1998. In 1999, 1998 and 1997, product sales from Betaseron-Registered Trademark- were $66.0 million, $63.4 million and $54.8 million, respectively. In 1999, the actual number of Betaseron-Registered Trademark- vials sold by Berlex and Schering AG to patients increased 20% over 1998, while Chiron's shipments of Betaseron-Registered Trademark- to Berlex and Schering AG decreased 19% over 1998. The increase in product sales in 1999 as compared with 1998 was primarily related to the approval in 1999 of Betaseron-Registered Trademark- for secondary progressive multiple sclerosis in Canada and Australia and overall market expansion, offset by the decrease in the contractual rate discussed above and the decrease in shipments of Betaseron-Registered Trademark- to Berlex and Schering AG. In 1998, Chiron's shipments of Betaseron-Registered Trademark- to Berlex and Schering AG increased significantly over shipments in 1997, while the actual number of vials sold by Berlex and Schering AG to patients in 1998 remained relatively constant with the number of vials sold in 1997. The increase in revenues in 1998 as compared with 1997 was primarily due to replenishing inventories at Berlex and Schering AG and to the change in payment terms discussed above. 18 The Company also earns royalties on Schering AG's European sales of Betaferon-Registered Trademark- (interferon beta-1b). See "Royalty and license fee revenues--Betaseron-Registered Trademark-" below. PDGF Chiron manufactures PDGF for Ortho-McNeil Pharmaceutical, Inc., a Johnson & Johnson ("J&J") company. PDGF is the active ingredient in Regranex-Registered Trademark-(becaplermin) Gel, a treatment for diabetic foot ulcers. Regranex-Registered Trademark- Gel was approved by the Food and Drug Administration ("FDA") in December 1997 and was launched commercially in early 1998. There were no commercial sales of PDGF to J&J in 1999, and sales of PDGF were $36.4 million and $18.3 million in 1998 and 1997, respectively. Chiron's sales of PDGF will tend to fluctuate based upon the inventory management practices of J&J. Regranex-Registered Trademark- Gel was approved for use in the treatment of diabetic foot ulcers in Canada in December 1998 and Europe in March 1999. However, even with these approvals, Chiron's sales through 1998 have filled J&J's inventory requirements through 1999, and as a result, no significant sales of PDGF to J&J are expected until the second quarter of 2000. As a result, the decline in sales from 1998 to 1999 was due to a lack of orders from J&J in 1999. In addition, the Company increased its product returns allowance in 1999. The increase in the product returns allowance was primarily due to additional historical returns information, now that Regranex-Registered Trademark- has been in the commercial market for over 12 months. As Regranex-Registered Trademark- is the first product of its kind, the Company believes it will take time for the market to fully develop. As Chiron's shipments of PDGF remained fairly constant in 1998 and 1997, the increase in revenues between 1998 and 1997 was primarily due to retroactive price increases recognized in 1998 for shipments made in 1997. The Company does not expect future price adjustments, if any, to be commensurate with those in 1998. VACCINE PRODUCT SALES Chiron sells pediatric and adult vaccines in Germany, Italy and other international markets. Certain of the Company's vaccine products, particularly its flu vaccine, are seasonal and typically have higher sales in the third quarter of the year. In 1999, 1998 and 1997, vaccine product sales were $208.6 million, $176.8 million and $82.0 million, respectively. The increase in sales in 1999 as compared with 1998 was driven by (i) the Company's acquisition of the remaining 51% interest in, and consolidation of, Chiron Behring in the second quarter of 1998 (see Chiron Behring below); (ii) increased flu vaccine sales due to a one-time $4.2 million sale of adult influenza vaccine to Argentina in the first quarter 1999 and growth in the flu vaccine market; and (iii) increased rabies vaccine sales as the Company gained additional market share. The increase in sales in 1998 as compared with 1997 was primarily due to Chiron's acquisition of the remaining 51% interest in, and consolidation of, Chiron Behring in the second quarter of 1998. In March 2000, the Company received approval in the United Kingdom to market Menjugate-TM-, its conjugate vaccine against meningococcal meningitis caused by the bacterium N. MENINGITIDIS serogroup C. The National Health Service ("NHS") in the United Kingdom has accepted the Company's tender to supply Menjugate-TM-. Shipments began in March 2000. The Company does not expect shipments in 2001 to be commensurate with those in 2000. The Company expects the competitive pressures related to many of its vaccine products to continue into the foreseeable future as a result of the introduction of competing products into the market, including new combination vaccines. BLOOD TESTING PRODUCT SALES During the second quarter 1999, the Company began recognizing revenues from sales of its nucleic acid tests that are used to screen blood and plasma under an investigational new drug ("IND") application in the U.S. Evaluation studies at several non-U.S. sites also began during the second quarter 1999. Worldwide product sales related to tests and instruments were $7.1 million for the year ended December 31, 1999. In September 1999, the Company received regulatory approval in France for the TMA assay and began selling and providing assays and renting instruments to several regional blood testing centers. Currently, the French government is considering the guidelines that it will adopt regarding nucleic acid testing, and Chiron is participating in a government-sponsored evaluation at four major testing centers to 19 support this decision. The outcome and impact of this upcoming decision on future assay sales and instrument rentals to French blood testing centers is not yet known. During the fourth quarter 1999, the Company signed an exclusive contract with the Australian Red Cross Blood Service to provide blood testing products for NAT screening. Under the contract, Chiron began recognizing product revenue for sales of its nucleic acid tests in Australia. EQUITY IN EARNINGS OF UNCONSOLIDATED JOINT BUSINESSES In 1999, 1998 and 1997, Chiron recognized equity in earnings of unconsolidated joint businesses of $79.3 million, $74.0 million and $106.4 million, respectively. In each of these years, equity in earnings of unconsolidated joint businesses consisted substantially of Chiron's 50% share of the pretax operating earnings generated by Chiron's joint business with Ortho-Clinical Diagnostics, Inc. ("Ortho"), a Johnson & Johnson company ("Chiron-Ortho joint business"). In 1998 and 1997, equity in earnings of unconsolidated joint businesses also included one quarter and four quarters, respectively, of earnings from Chiron's 49% share of the after-tax operating results of Chiron Behring. CHIRON-ORTHO JOINT BUSINESS In 1999, 1998 and 1997, Chiron's 50% share of the pretax operating earnings of the Chiron-Ortho joint business was $78.1 million, $73.5 million and $92.9 million, respectively. The overall fluctuations in earnings from the joint business were primarily due to certain adjustments made during the first quarters of 1999, 1998 and 1997. In the first quarter of 1999, an annual inventory adjustment resulted in a charge of $0.7 million as compared with a charge of $4.1 million recognized in the first quarter 1998. In the first quarter 1998, an annual inventory adjustment resulted in a charge of $4.1 million as compared with $0.8 million of income in the first quarter 1997. Other items contributing to the decrease in earnings in 1998 as compared with 1997 were (i) lower foreign profits of the joint business due to the adverse impact of changes in foreign currency exchange rates between years and higher manufacturing costs; (ii) a one-time contract termination fee paid by the Chiron-Ortho joint business in the first quarter 1998; and (iii) certain joint business asset write-offs related to the implementation of certain processes to comply with stricter FDA guidelines mandated throughout the industry. CHIRON BEHRING On July 1, 1996, Chiron acquired a 49% interest in Chiron Behring. On March 31, 1998, Chiron acquired the remaining 51% interest in Chiron Behring (see Note 5 of NOTES TO CONSOLIDATED FINANCIAL STATEMENTS). From July 1, 1996 through the first quarter 1998, equity in earnings of unconsolidated joint businesses included Chiron's 49% share of the after-tax operating results of Chiron Behring. Chiron's share of earnings from the joint business, including amortization of intangibles, was $2.4 million for the three months ended March 31, 1998 and $13.8 million for the year ended December 31, 1997. Beginning March 31, 1998, Chiron Behring's results were consolidated with those of the Company. COLLABORATIVE AGREEMENT REVENUES Chiron recognizes collaborative agreement revenues for fees received for research services as they are performed and fees received upon the achievement of specified milestones. Collaborative agreement revenues tend to fluctuate based on the amount of research services performed, the status of projects under collaboration and the achievement of milestones. Due to the nature of the Company's collaborative agreement revenues, results in any one year are not necessarily indicative of results to be achieved in the future. The Company's ability to generate additional collaborative agreement revenues may depend, in part, on its ability to initiate and maintain relationships with potential and current collaborative partners. There can be no assurance that such relationships will be established or that current collaborative agreement revenues will not decline. In particular, the research funding from Novartis (see below) expires on December 31, 2000, and there can be no assurance that new relationships will be established. Significant fluctuations in collaborative agreement revenues from year-to-year are discussed below. NOVARTIS AG Chiron and Novartis AG ("Novartis") entered into an agreement under which Novartis agreed to provide research funding for certain projects. The funded projects currently consist of adult and pediatric vaccines, Insulin-Like Growth Factor-I, Factor VIII and Herpes Simplex Virus-thymidine kinase 20 ("HSV-tk"). Novartis has agreed to fund through December 31, 2000, at Chiron's request and subject to certain annual and aggregate limits, up to 100% of the development costs incurred between January 1, 1995 and December 31, 1999 on these projects. In December 1999, Chiron and Novartis amended this agreement to increase the aggregate maximum amount of funding provided by Novartis from $250.0 million to $265.0 million. Under this agreement, in 1999, 1998 and 1997, Chiron recognized collaborative agreement revenues of $46.2 million, $54.4 million and $53.3 million, respectively. Under the terms of a November 1995 agreement with Novartis, Chiron granted Novartis a license to utilize Chiron's combinatorial chemistry techniques. In exchange for this license, Novartis agreed to pay Chiron $26.0 million over a five-year period, subject to certain adjustments. In addition, this agreement provides for research funding by Novartis, and certain upfront milestone and royalty payments, as well as product commercialization rights for both parties. In connection with this agreement, Chiron recognized collaborative agreement revenues of $4.2 million, $6.0 million and $10.2 million in 1999, 1998 and 1997, respectively. In November 1996, Chiron and Novartis entered into a consent order with the Federal Trade Commission pursuant to which Chiron agreed to grant a royalty-bearing license to Rhone-Poulenc Rorer, Inc. under certain Chiron patents related to the HSV-tk gene in the field of gene therapy. Chiron and Novartis entered into a separate agreement which provided, among other things, for certain cross licenses between Chiron and Novartis, and under which, Novartis agreed to pay Chiron up to $60.0 million over five years. In connection with this agreement, Chiron recognized collaborative agreement revenues of $10.0 million in 1999 and $15.0 million in both 1998 and 1997. JAPAN TOBACCO In 1996, Japan Tobacco licensed Chiron's combinatorial chemistry technologies for use in its research and development programs. The agreement, which was terminated in 1998, included certain funding for Chiron's effort in transferring the technology. Revenues recognized under this agreement were $1.0 million and $7.8 million in 1998 and 1997, respectively. The Company has no continuing obligation under this agreement. GREEN CROSS OF JAPAN In 1995, Green Cross of Japan agreed to reimburse Chiron for certain HIV research, product development and clinical trials. In 1998, the clinical trials related to this collaboration were discontinued. In 1998 and 1997, Chiron recognized revenues related to this agreement of $1.2 million and $5.4 million, respectively. The Company has no continuing obligation under this agreement. MEDIVIR AB In 1999, Medivir licensed some of Chiron's combinatorial technology-based techniques for drug discovery and optimization, for use in the research and development of pharmaceuticals for human use. Revenue recognized under this agreement was $2.0 million in 1999. If Medivir commercializes a product using Chiron's combinatorial technology, Chiron will receive up to an additional $3.6 million in royalties on product sales. However, there can be no assurance that Medivir will commercialize a product using Chiron's combinatorial technology. ROYALTY AND LICENSE FEE REVENUES The Company receives royalties and license fees for products or technologies that are manufactured, used or sold by third parties. In 1999, 1998 and 1997, Chiron recognized royalty and license fee revenues of $133.2 million, $125.3 million and $50.4 million, respectively. Royalty and license fee revenues may fluctuate based on the nature of the related agreements and the timing of receipt of license fees. Results in any one year are not necessarily indicative of results to be achieved in the future. In addition, the Company's ability to generate additional royalty and license fee revenues may depend, in part, on its ability to market and capitalize on its technologies. Significant fluctuations in royalty and license fee revenue from year-to-year are discussed below. BETASERON-REGISTERED TRADEMARK- The Company earns royalties on Schering AG's European sales of Betaferon-Registered Trademark- (interferon beta-lb). In 1999, 1998 and 1997, Chiron recognized $29.7 million, $28.6 million and $24.1 million, respectively, under this arrangement. The increase in 1999 as compared with 1998 was primarily related to the approval in 1999 of Betaseron-Registered Trademark- for secondary progressive multiple sclerosis in Europe and 21 overall market expansion, offset by the decrease in the contractual rate discussed above. The increase in 1998 as compared with 1997 was due to continued market expansion. The Company also earns revenues on Betaseron-Registered Trademark- product sales to Berlex and Schering AG. See "Biopharmaceutical product sales--Betaseron-Registered Trademark-" above. ROCHE PCR AGREEMENT In accordance with a July 1991 agreement with F. Hoffman-LaRoche Ltd. and its affiliates ("Roche"), the Company receives royalties on sales of polymerase chain reaction ("PCR") products sold by Roche. In 1999 and 1998, Chiron recognized $15.8 million and $15.2 million, respectively, of royalty and license fee revenues related to this agreement. Based on the terms of the agreement, Chiron does not earn royalties on PCR products until Roche's annual net sales of PCR products and services exceed $200.0 million (the "threshold amount"). As the threshold amount resets at the beginning of each year, Roche's annual net sales must exceed $200.0 million before Chiron will earn any royalties. As a result, the Company does not expect to recognize royalties under this agreement until the last half of each year. Roche's royalty obligation expires upon the earlier of December 31, 2000 or when Chiron recognizes royalties with an aggregate net present value of $30.0 million as of the date of the agreement (discounted at 14.0%). As of December 31, 1999, Chiron had recognized royalties with a net present value of $13.2 million. BAYER CROSS-LICENSE AGREEMENT In connection with the sale of Chiron Diagnostics to Bayer, Chiron granted to Bayer rights under certain Chiron patents, including rights under patents relating to HIV and hepatitis C virus ("HCV"). In exchange for these rights, Bayer paid to Chiron a license fee of $100.0 million, which is refundable in decreasing amounts over a period of three years. In 1999 and 1998, Chiron recognized revenues of $39.2 million and $13.3 million, respectively, which represent the portions of the $100.0 million payment which became nonrefundable during those years. The Company anticipates recognizing the remaining revenue over the next two years as follows: $29.2 million in 2000 and $18.3 million in 2001. In addition, the Company receives royalties on sales of HIV and HCV products sold by Bayer. In 1999, Chiron recognized $5.1 million of royalty revenue related to this agreement. LICENSE FEE REVENUES In January 1998, Chiron recognized $5.0 million related to a license fee received from Pharmacia & Upjohn Company to research, develop, manufacture and commercialize therapeutic products for the treatment of HCV in humans. In August 1998, Chiron recognized $24.0 million related to a license fee received from SmithKline Beecham to use certain human vaccine product technologies. The agreement provides for royalties on future product sales, under which Chiron recognized $7.3 million and $3.7 million of such royalties in 1999 and 1998, respectively. OTHER In 1999 and 1998, Chiron recognized $11.3 million and $9.4 million, respectively, of royalty and license fee revenues due to the acquisition and consolidation of Chiron Behring in the second quarter of 1998. OTHER REVENUES In 1999, 1998 and 1997, Chiron recognized other revenues of $52.2 million, $48.3 million and $50.1 million, respectively. The Company's other revenues may fluctuate due to the nature of the revenues recognized and the timing of events giving rise to these revenues. Significant fluctuations in other revenues from year-to-year are discussed below. COMMISSION REVENUES In 1999 and 1998, other revenues included $13.5 million and $10.4 million, respectively, of commission revenues generated by Chiron Behring, whose operations were consolidated with those of the Company beginning in the second quarter 1998. These revenues consist of commissions received on sales made by Chiron Behring of Pasteur Merieux Merck's hepatitis B virus ("HBV") vaccine products and of Aventis Behring GmbH's (formerly Centeon Pharma GmbH) immunoglobulin products. INFORMATICS TECHNOLOGY Chiron recognized net revenues of $12.5 million in 1998 in exchange for granting Bayer a license to use, reproduce and sell certain technology developed by Chiron's informatics 22 business. The Company ceased all informatics activity in 1998; therefore, the Company does not anticipate future revenues from this technology. AREDIA-REGISTERED TRADEMARK- (PAMIDRONATE DISODIUM FOR INJECTION) From 1994 through April 1998, Chiron promoted Aredia-Registered Trademark- on behalf of Novartis. In April 1998, this arrangement was terminated. In connection with this arrangement, Chiron recognized other revenues of $9.8 million and $43.6 million in 1998 and 1997, respectively. CONTRACT MANUFACTURING REVENUES In 1999 and 1998, other revenues included $19.2 million ($13.3 million in the biopharmaceuticals segment and $5.9 million in the vaccines segment) and $9.0 million ($1.4 million in the biopharmaceuticals segment and $7.6 million in the vaccines segment), respectively, of contract manufacturing revenues. The increase was a result of new contract manufacturing agreements, which began in 1999. The Company anticipates that it will enter into additional contract manufacturing agreements. DEPOCYT-REGISTERED TRADEMARK- In 1999, other revenues included a $9.7 million milestone payment related to the FDA's approval of DepoCyt-Registered Trademark- in April 1999. In October 1999, SkyePharma, Inc. ("SkyePharma"), the manufacturer of DepoCyt-Registered Trademark-, discovered two DepoCyt-Registered Trademark- lots that did not meet manufacturing specifications and, as a result, all DepoCyt-Registered Trademark- vials were recalled from these lots. The commercial supply of this product is on hold while the Company and SkyePharma work with the FDA to resolve various issues related to the manufacture of the product. Management of the Company does not believe that this event will have a material impact on the results of operations for fiscal year 2000. The impact of this event on future shipments of DepoCyt-Registered Trademark- is not yet known. COSTS AND EXPENSES GROSS PROFIT Gross profit as a percentage of net product sales was 56.3%, 56.2% and 54.9% in 1999, 1998 and 1997, respectively. Although 1999 gross profit as a percentage of net product sales remained relatively constant with that in 1998, the Company's 1999 gross profit percentage was impacted by (i) an increase in biopharmaceutical products gross profit due to manufacturing efficiencies and the conclusion of certain promotional pricing campaigns; and (ii) a slight increase in vaccines product gross profit due to manufacturing efficiencies resulting from increased production and a favorable mix of vaccine product sales; offset by (iii) an inventory write-off of a portion of the Company's tick-borne encephalitis vaccine inventory that failed to meet manufacturing specifications for purity during the first quarter 1999; and (iv) no 1999 commercial sales of PDGF. The Company's 1998 gross profit percentage was impacted by a reduction in cost of sales of $6.0 million due to a change in estimated property tax accruals created in prior periods, offset by an unfavorable mix of vaccine products which, beginning in the second quarter of 1998, included low margin products manufactured and sold by Chiron Behring. The Company's gross profit percentages may fluctuate significantly in future periods as the Company's product mix continues to evolve. RESEARCH AND DEVELOPMENT In 1999, 1998 and 1997, Chiron recognized research and development expenses of $303.4 million, $286.6 million and $256.6 million, respectively. The Company's research and development expenses may fluctuate from year-to-year depending upon the level of clinical trial-related activities. In 1999, the increase in research and development spending as compared with 1998 was due, in part, to $9.6 million of milestone and research funding payments related to the Company's collaboration agreements with Medivir AB and $5.0 million of license fees related to the Company's Fibroblast Growth Factor ("FGF") patent and license agreement with Scios, Inc. Under this agreement, in 1999, the Company also advanced Scios an additional $7.5 million in exchange for a promissory note, which may be forgiven if certain conditions are met. The Company may pay an additional $12.0 million in licensing fees if certain development objectives are met. Also contributing to the increase in research and development 23 expense was the furtherance of the Company's clinical trials related to Proleukin-Registered Trademark- for HIV, Insulin-Like Growth Factor-1 ("IGF-1") for osteoarthritis, FGF for coronary artery disease, Tissue Factor Pathway Inhibitor ("TFPI") for sepsis and Menjugate-TM-, a conjugate vaccine against meningococal meningitis caused by the bacterium N. MENINGITIDIS serogroup C. In 1998, the increase in research and development spending as compared with 1997 was primarily related to several of the Company's projects entering into later stage clinical development. In addition, included in research and development expense in 1998 was $14.1 million of expense generated by Chiron Behring, which was acquired and consolidated during the second quarter of 1998. These increases were partially offset by decreased spending related to Myotrophin-Registered Trademark- (rhIGF-I or mecasermin [recombinant DNA origin]) due to the uncertainty surrounding the FDA's approval of this product (see "Item 1. Business" above). SELLING, GENERAL AND ADMINISTRATIVE In 1999, 1998 and 1997, Chiron recognized selling, general and administrative ("SG&A") expenses of $180.9 million, $142.6 million and $108.8 million, respectively. The increase in SG&A expenses in 1999 as compared with 1998 was primarily due to the acquisition and consolidation of Chiron Behring, which contributed an additional $10.7 million to SG&A expenses in 1999. SG&A expenses also increased as a result of the Company's worldwide implementation of its integrated information system in April 1999, the launch of the nucleic acid testing business of its blood testing segment and certain patent defense legal costs. The increase in SG&A expenses in 1998 as compared with 1997 was primarily due to the acquisition and consolidation of Chiron Behring, which contributed $34.3 million to SG&A expenses in 1998. OTHER OPERATING EXPENSES As circumstances dictate, the Company reviews the carrying amount of its manufacturing facilities by comparing the facilities' projected undiscounted net cash flows against their respective carrying values. In 1997, the Company recognized a $31.3 million impairment loss to record the Puerto Rico facility and related machinery and equipment assets at their individual estimated fair market values, determined on the basis of independent appraisals. In 1999, Chiron recorded net restructuring and reorganization expenses of $0.2 million, which included a charge of $3.9 million and a benefit of $3.7 million. The charge of $3.9 million primarily related to termination and other employee related costs recognized in connection with the elimination of 28 positions at the Company's Italian manufacturing facility. As of December 31, 1999, 24 of these 28 positions had been eliminated. The benefit of $3.7 million related to revised estimates of property-related accruals recorded in connection with the Company's ongoing rationalization of its business operations and the idling of the St. Louis facility, as well as revised estimates of termination and other employee-related costs recorded in connection with the elimination of 382 positions, including 36 positions at the Company's Amsterdam facility which were transferred to the buyer in January 2000 (see below). As of December 31, 1999, 319 of these 382 positions had been eliminated. In 1998, the Company recorded net restructuring and reorganization expenses of $26.8 million, which included a charge of $30.5 million and a benefit of $3.7 million. The charge of $30.5 million related to termination, other employee-related costs and facility- related costs recorded in connection with the elimination of 400 positions. The benefit of $3.7 million related to revised estimates of property and other tax-related accruals recorded in connection with the idling of the Puerto Rico facility. The liabilities related to the restructuring and reorganization expenses are expected to be substantially settled within one year of accruing the related charges. Management expects employee and facility-related cost savings due to these restructuring activities in cost of sales, research and development expense and selling, general and administrative expense through 2008. As of December 31, 1999, the Company believes that it has begun to achieve these cost savings in the line items outlined above. In 1999, Chiron recognized a reduction in other operating expenses of $13.4 million resulting from a change in estimated tax accruals related to certain employee payments recorded in 1995 under a series of agreements between Chiron and Novartis. 24 NON-OPERATING INCOME AND EXPENSE In December 1999, the Company sold its manufacturing facility in Amsterdam, resulting in a gain of $0.9 million. In August 1998, Chiron completed the sale of its manufacturing facility in St. Louis, Missouri, resulting in a gain on sale of assets of $1.5 million. In addition, in June 1998, the Company sold its fill and finishing facility in Puerto Rico, resulting in a gain of $6.2 million. In December 1999, the Company sold certain assets that it had developed or acquired in connection with its research and development of a Cytomegalovirus ("CMV") vaccine to Aventis Pasteur and recognized a gain of $7.5 million. In 1999, 1998 and 1997, Chiron recognized interest expense of $23.9 million, $24.7 million and $31.6 million, respectively. The decrease in interest expense in 1999 as compared with 1998 was primarily due to lower average debt balances. The decrease in interest expense in 1998 as compared with 1997 was primarily due to the repayment of $100.0 million on the Company's lines of credit in January 1998. The borrowings were outstanding under the Company's U.S. credit facilities and were repaid with a portion of the proceeds received from the sale of Chiron Diagnostics. Other income, net, consists primarily of interest and investment income on the Company's cash and investment balances and other non-operating gains and losses. In 1999, 1998 and 1997, Chiron recognized interest and investment income of $83.8 million, $29.6 million and $12.0 million, respectively. The increase in interest income in 1999 as compared with 1998 was primarily due to higher average cash and investment balances attributable to the net cash proceeds received from the sale of Chiron Vision in the first quarter 1998 and Chiron Diagnostics in the fourth quarter 1998. In connection with its research and development collaborations, the Company may invest in equity securities of its collaborative partners. The price of these securities is subject to significant volatility. In 1999, 1998 and 1997, Chiron recognized a loss attributable to the other-than-temporary impairment of certain of these equity securities of $1.7 million, $8.4 million and $1.2 million, respectively. In 1999, 1998 and 1997, Chiron recognized gains of $3.8 million, $4.5 million and $5.5 million, respectively, related to the sale of certain equity securities. In addition, in 1999, Chiron recognized an unrealized holding gain of $3.3 million related to equity securities classified as trading. On December 31, 1998, Chiron completed the sale of its 30% interest in General Injectibles & Vaccines, Inc. ("GIV"), a distribution business, to Henry Schein, Inc. and received payment in full of certain advances made by the Company to GIV, for a total of $31.7 million in cash. The sale resulted in a net gain of $1.8 million. INCOME TAXES In 1999, the annual tax provision was 26.2% of pretax income from continuing operations. The reported effective tax rate for 1999 was 18.0% of pretax income from continuing operations, including the impact of the reversal of a prior year valuation allowance, which resulted in the recognition of additional domestic deferred tax benefits of $12.9 million. In 1998, the annual tax provision was 25.8% of pretax income from continuing operations, excluding restructuring and reorganization charges, a financial reporting gain on the sale of the Puerto Rico facility and $6.0 million of financial reporting income recognized in 1998 due to a change in estimated property tax accruals. The increase in the effective tax rate in 1999 as compared with 1998, as adjusted above, is primarily due to the benefit of certain tax losses and other tax benefits realized in 1998, substantially offset by a higher proportion of non-U.S. income subject to tax at lower rates in 1999. 25 In 1997, the annual tax provision was 20.2% of pretax income from continuing operations, excluding the impact of the impairment loss on the Puerto Rico facility, which did not create a corresponding income tax benefit in the year recorded. NEW ACCOUNTING STANDARD In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS 133"), which establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. In June 1999, SFAS 133 was amended by SFAS No. 137, "Accounting for Derivative Instruments and Hedging Activities--Deferral of the Effective Date of SFAS 133." As a result of this amendment, SFAS 133 shall be effective for all fiscal quarters of all fiscal years beginning after June 15, 2000. In accordance with SFAS 133, an entity is required to recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value. SFAS 133 requires that changes in the derivative's fair value be recognized currently in earnings unless specific hedge accounting criteria are met. Special accounting for qualifying hedges allows a derivative's gains and losses to offset related results on the hedged item in the income statement and requires that a company formally document, designate and assess the effectiveness of transactions that receive hedge accounting. The Company is currently evaluating the effect that implementation of SFAS 133 will have on its results of operations and financial position and anticipates that it will implement SFAS 133 during the first quarter of 2001. LIQUIDITY AND CAPITAL RESOURCES Chiron's capital requirements have generally been funded from operations, cash and investments on hand, debt borrowings, issuance of common stock and off-balance sheet financing. Chiron's cash, investments in marketable debt securities and short-term investment in equity securities, which totaled $1.6 billion at December 31, 1999, are invested in a diversified portfolio of financial instruments, including money market instruments, corporate notes and bonds, government or government agency securities, and other debt and equity securities, issued by financial institutions of high credit standing. By policy, the amount of credit exposure to any one institution is limited; however, these investments are generally not collateralized and primarily mature within three years. SOURCES AND USES OF CASH Chiron had cash and cash equivalents of $363.9 million and $513.3 million at December 31, 1999 and 1998, respectively. In 1999, net cash provided by operating activities was $20.9 million as compared with $231.7 million in 1998. The decrease in cash provided by operating activities was largely due to $183.4 million in estimated tax payments related to the sale of Chiron Diagnostics, which was partially offset by $60.2 million in federal and state tax refunds received and net income of $160.6 million. In 1999, net cash used in investing activities consisted of purchases of investments in marketable debt securities of $1.2 billion, capital expenditures of $64.6 million and other uses of cash of $16.7 million. These uses of cash were partially offset by proceeds from the sale and maturity of investments in marketable debt securities of $1.0 billion, proceeds from the disposal of discontinued operations of $46.9 million and proceeds from the sale of assets, equity securities and interest in affiliated companies of $25.5 million. In 1998, net cash provided by investing activities consisted of proceeds from the sale of Chiron Vision and Chiron Diagnostics of $1.3 billion, proceeds from the sale and maturity of investments in marketable debt securities of $282.7 million and proceeds from the sale of assets, equity securities and interest in affiliated companies of $62.7 million. These uses of cash were partially offset by the purchase of Chiron Behring of $54.8 million (net of cash acquired), purchases of investments in marketable debt securities of $1.2 billion and capital expenditures of $126.3 million. 26 In 1999, net cash used in financing activities consisted of $15.3 million related to short-term borrowings, $2.4 million related to the repayment of debt and capital leases and $140.8 million related to the acquisition of treasury stock. These uses of cash were partially offset by proceeds of $98.2 million from the issuance of common stock and the reissuance of treasury stock related to stock option exercises and employee stock purchases and $6.9 million in proceeds from the issuance of long-term debt. In 1998, net cash used in financing activities consisted of $129.1 million related to short-term borrowings and $9.1 million related to the repayment of debt and capital leases. These uses of cash were partially offset by proceeds of $66.6 million from the issuance of common stock related to stock option exercises and employee stock purchases. The Company is currently evaluating a number of business development opportunities. To the extent that the Company is successful in reaching agreements with third parties, these transactions may involve the expenditure of a significant amount of the Company's current investment portfolio. The Company's 1.9% convertible subordinated debentures are due in November 2000. BORROWING ARRANGEMENTS Under a revolving, committed, unsecured credit agreement with a major financial institution, Chiron can borrow up to $100.0 million in the U.S. This credit facility is guaranteed by Novartis under a November 1994 Investment Agreement, provides various interest rate options and matures in February 2003. There were no borrowings outstanding under this credit facility at December 31, 1999. Chiron also has credit facilities outside the U.S. which allow for total borrowings of $63.1 million. Under these credit facilities, $20.3 million of borrowings were outstanding at December 31, 1999. In December 1999, Chiron and Novartis amended the November 1994 Investment Agreement. This amendment reduced the maximum amount of Chiron obligations that Novartis will guarantee from $725.0 million to $702.5 million. In connection with the sale of Chiron Diagnostics to Bayer, a promissory note owed by Chiron Diagnostics to Novartis was transferred to and assumed by the Company. The note payable to Novartis bears interest at a variable rate based on LIBOR (approximately 5.7% and 5.6% at December 31, 1999 and 1998, respectively). As of December 31, 1999 and 1998, the outstanding amount was $67.8 million and $63.9 million, respectively, including accrued interest. The note and accrued interest were paid in full on January 4, 2000. LEASES Chiron leases laboratory, office and manufacturing facilities, land and equipment under noncancelable operating leases, which expire through 2009. Future minimum lease payments, including those for the leaseback of office and warehouse space in the Amsterdam facility, are estimated to be approximately $130.3 million in the aggregate, excluding a residual value guarantee of $172.6 million due upon termination of an operating lease in 2003. As of December 31, 1999, Novartis had guaranteed $172.6 million of the Company's operating lease commitments (refer to Note 8 of the NOTES TO CONSOLIDATED FINANCIAL STATEMENTS). OTHER COMMITMENTS Effective July 1, 1998, Chiron and International Business Machines Corporation ("IBM") entered into a ten-year information technology services agreement under which IBM will provide Chiron with a full range of information services. Chiron can terminate this agreement beginning July 1, 1999, subject to certain termination charges. If Chiron does not terminate this agreement, payments to IBM are expected to be approximately $111.8 million. Payments to IBM are subject to adjustment depending upon the level of services and infrastructure equipment provided by IBM, as well as inflation. In future periods, the Company expects to incur substantial capital spending. At December 31, 1999, the Company had various firm purchase and capital project commitments totaling approximately $6.8 million. At December 31, 1999, the Company had $5.1 million outstanding under a letter of credit, which is 27 required by German law, related to ongoing legal proceedings in Germany (see Item 3. "Legal Proceedings" above). The Company also had various performance bonds and insurance-related letters of credit in the amount of $4.9 million outstanding at December 31, 1999. MARKET RISK MANAGEMENT The Company's cash flow and earnings are subject to fluctuations due to changes in foreign currency exchange rates, interest rates and fair value of equity securities held. The Company attempts to limit its exposure to some or all of these market risks through the use of various financial instruments. These activities are discussed in further detail in Item 7A., "Quantitative and Qualitative Disclosures About Market Risk." YEAR 2000 Chiron developed a comprehensive risk-based plan designed to make its computer hardware and communication systems, software applications and facilities and other non-information technology-related functions Year 2000 compliant. The Company did not experience any upsets or failures in systems during the year-end rollover. The Company did experience some minor date related-problems in non-critical software applications after the year-end rollover; however, these problems were identified and resolved with no impact to the Company's operations. As part of the Company's contingency plans, teams monitored critical systems at each site during the year-end rollover. No backup contingency plans required execution. The Company did not experience delays in shipment of products to customers or in delivery of materials from vendors related to the Year 2000. Business partners have not reported any Year 2000 system upsets or failures that would impact the Company's operations. The Company sold its facility in Amsterdam, The Netherlands in December 1999. This facility did not experience any upsets or failures in its systems related to the Year 2000. The Company monitored its computer hardware and communication systems, software applications and facilities and other non-information technology-related functions for Year 2000 issues through the leap year. Except for the minor date-related problems in non-critical software applications mentioned above, the Company did not experience any additional Year 2000 problems. The Company intends to monitor these systems through March 31, 2000. As of February 29, 2000, total costs incurred to date were funded through operations and approximated $3.6 million. The Company expects an additional $0.1 million in Year 2000 expenditures through March 31, 2000, which it will fund with cash on hand and cash generated through operations. EURO CONVERSION On January 1, 1999, eleven European Union member countries established fixed conversion rates between their existing currencies ("legacy currencies") and one common currency, the Euro. The Euro is currently traded on currency exchanges and can be used in business transactions. The Company's financial systems are Euro ready as of December 31, 1999. However, the Company is still in the process of evaluating the effect, if any, of the Euro on the Company's product pricing and gross profit percentages. FACTORS THAT MAY AFFECT FUTURE RESULTS As a biotechnology company, Chiron is engaged in a rapidly evolving and often unpredictable business. The forward-looking statements contained in this Report and in other periodic reports, press releases and other statements issued by the Company from time to time reflect management's current beliefs and expectations concerning objectives, plans, strategies, future performance and other future events. The following discussion highlights some of the factors, many of which are beyond the Company's control, which could cause actual results to differ. 28 PROMISING TECHNOLOGIES ULTIMATELY MAY NOT PROVE SUCCESSFUL The Company focuses its research and development activities on areas in which it has particular strengths and on technologies that appear promising. These technologies often are on the "cutting edge" of modern science. As a result, the outcome of any research or development program is highly uncertain. Only a very small fraction of such programs ultimately result in commercial products or even product candidates. Product candidates that initially appear promising often fail to yield successful products. In many cases, preclinical or clinical studies will show that a product candidate is not efficacious (that is, it does not have the intended therapeutic or prophylactic effect), or that it raises safety concerns or has other side effects which outweigh the intended benefit. Success in preclinical or early clinical trials (which generally focus on safety issues) may not translate into success in large-scale clinical trials (which are designed to show efficacy), often for reasons that are not fully understood. And even after a product is approved and launched, general usage or post-marketing studies may identify safety or other previously unknown problems with the product which may result in regulatory approvals being suspended, limited to narrow indications or revoked, or which may otherwise prevent successful commercialization. REGULATORY APPROVALS The Company is required to obtain and maintain regulatory approval in order to market most of its products. Generally, these approvals are on a product-by-product and country-by-country basis, and, in the case of therapeutic products, a separate approval is required for each therapeutic indication. See Item 1. "Business--Government Regulation." Product candidates that appear promising based on early, and even large-scale, clinical trials may not receive regulatory approval. The results of clinical trials often are susceptible to varying interpretations that may delay, limit or prevent approval or result in the need for post-marketing studies. MANUFACTURING Most of the Company's products are biologics. Manufacturing biologic products is complex. Unlike chemical pharmaceuticals, a biologic product generally cannot be sufficiently characterized (in terms of its physical and chemical properties) to rely on assaying of the finished product alone to ensure that the product will perform in the intended manner. Accordingly, it is essential to be able to both validate and control the manufacturing process: that is, to show that the process works and that the product is made strictly and consistently in compliance with that process. Slight deviations in the manufacturing process may result in unacceptable changes in the products that may result in lot failures. Manufacturing processes which are used to produce the (smaller) quantities of material needed for research and development purposes may not be successfully scaled up to allow production of commercial quantities at reasonable cost or at all. All of these difficulties are compounded when dealing with novel biologic products that require novel manufacturing processes. Accordingly, manufacturing is subject to extensive government regulation. Even minor changes in the manufacturing process require regulatory approval, which, in turn, may require further clinical studies. PATENTS HELD BY THIRD PARTIES MAY DELAY OR PREVENT COMMERCIALIZATION Third parties, including competitors, have patents and patent applications in the U.S. and other significant markets that may be useful or necessary for the manufacture, use or sale of certain of the Company's products and products in development. It is likely that third parties will obtain other such patents in the future. Certain of these patents may be sufficiently broad to prevent or delay Chiron from manufacturing or marketing products important to the Company's current and future business. The scope, validity and enforceability of such patents, if granted, the extent to which Chiron may wish or need to obtain licenses to such patents, and the cost and availability of such licenses cannot be accurately predicted. If Chiron does not obtain such licenses, products may be withdrawn from the market or delays could be encountered in market introduction while an attempt is made to design around such patents. 29 Alternatively, Chiron could find that the development, manufacture or sale of such products is foreclosed. Chiron could also incur substantial costs in challenging the validity and scope of such patents. PRODUCT ACCEPTANCE The Company may experience difficulties in launching new products, many of which are novel products based on technologies that are unfamiliar to the healthcare community. There can be no assurance that healthcare providers and patients will accept such products. In addition, government agencies, as well as private organizations involved in healthcare, from time to time publish guidelines or recommendations to healthcare providers and patients. Such guidelines or recommendations can be very influential and may adversely affect the usage of the Company's products directly (for example, by recommending a decreased dosage of the Company's product in conjunction with a concomitant therapy) or indirectly (for example, by recommending a competitive product over the Company's product). COMPETITION Chiron operates in a highly competitive environment, and the competition is expected to increase. Competitors include large pharmaceutical, chemical and blood testing companies, as well as biotechnology companies. Some of these competitors, particularly large pharmaceutical and blood testing companies, have greater resources than the Company. Accordingly, even if the Company is successful in launching a product, it may find that a competitive product dominates the market for any number of reasons, including the possibility that the competitor may have launched its product first; the competitor may have greater marketing capabilities; or the competitive product may have therapeutic or other advantages. The technologies applied by the Company and its competitors are rapidly evolving, and new developments frequently result in price competition and product obsolescence. CHIRON'S PATENTS MAY NOT PREVENT COMPETITION OR GENERATE REVENUES Chiron seeks to obtain patents on its inventions. Without the protection of patents, competitors may be able to use the Company's inventions to manufacture and market competing products without being required to undertake the lengthy and expensive development efforts made by Chiron and without having to pay royalties or otherwise compensate Chiron for the use of the invention. There can be no assurance that patents and patent applications owned or licensed to Chiron will provide substantial protection. Important legal questions remain to be resolved as to the extent and scope of available patent protection for biotechnology products and processes in the U.S. and other important markets. It is not known how many of the Company's pending patent applications will be granted, or the effective coverage of those that are granted. In the U.S. and other important markets, the issuance of a patent is neither conclusive as to its validity nor the enforceable scope of its claims. The Company has engaged in significant litigation to determine the scope and validity of certain of its patents and expects to continue to do so in the future. Even if the Company is successful in obtaining and defending patents, there can be no assurance that these patents will provide substantial protection. The length of time necessary to successfully resolve patent litigation may allow infringers to gain significant market advantage. Third parties may be able to design around the patents and develop competitive products that do not use the inventions covered by the patents. Many countries, including certain countries in Europe, have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties (for example, the third party's product is needed to meet a threat to public health or safety in that country, or the patent owner has failed to "work" the invention in that country, or the third party has patented improvements), and most countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may be limited to monetary relief and may be unable to enjoin infringement, which could materially diminish the value of the patent. 30 AVAILABILITY OF REIMBURSEMENT; GOVERNMENT AND OTHER PRESSURES ON PRICING In the U.S. and other significant markets, sales of the Company's products may be affected by the availability of reimbursement from the government or other third parties, such as insurance companies. It is difficult to predict the reimbursement status of newly approved, novel biotechnology products, and current reimbursement policies for existing products may change. In certain foreign markets, governments have issued regulations relating to the pricing and profitability of pharmaceutical companies. There have been proposals in the U.S. (at both the federal and state level) to implement such controls. The growth of managed care in the U.S. also has placed pressure on the pricing of healthcare products. These pressures can be expected to continue. COSTS ASSOCIATED WITH EXPANDING THE BUSINESS Management expects to grow the business in areas in which the Company can be most competitive, either through in-licensing, collaborations or acquisitions of products or companies. In connection with these efforts, the Company may incur significant charges, costs and expenses, which could impact the Company's profitability, including impairment losses, restructuring charges, the write-off of purchased in-process technology, transaction-related expenses, costs associated with integrating new businesses and the cost of amortizing goodwill and other intangibles. OTHER NEW PRODUCTS AND SOURCES OF REVENUE Many products in the Company's current pipeline are in relatively early stages of research or development. The Company's ability to grow earnings in the near-to medium-term may depend, in part, on its ability to initiate and maintain other revenue generating relationships with third parties, such as licenses to certain of the Company's technologies, and on its ability to identify and successfully acquire rights to later-stage products from third parties. There can be no assurance that such other sources of revenue will be established. INTEREST RATE AND FOREIGN CURRENCY EXCHANGE RATE FLUCTUATIONS In 1998, the Company sold certain businesses for cash, including its IN VITRO diagnostics and ophthalmics businesses, and as a result has significant cash balances and short-term investments. The Company's financial results, therefore, are sensitive to interest rate fluctuations in the U.S. In addition, the Company sells products in many countries throughout the world, and its financial results could be significantly affected by fluctuations in foreign currency exchange rates or by weak economic conditions in foreign markets. COLLABORATION PARTNERS An important part of the Company's business strategy depends upon collaborations with third parties, including research collaborations and joint efforts to develop and commercialize new products. As circumstances change, the Company and its corporate partners may develop conflicting priorities or other conflicts of interest. The Company may experience significant delays and incur significant expenses in resolving these conflicts and may not be able to resolve these matters on acceptable terms. Even without conflicts of interest, the parties may differ in their views as to how best to realize the value associated with a current product or a product in development. In some cases, the corporate partner may have responsibility for formulating and implementing key strategic or operational plans. Decisions by corporate partners on key clinical, regulatory, marketing (including pricing), inventory management and other issues may prevent successful commercialization of the product or otherwise impact the Company's profitability. 31 STOCK PRICE VOLATILITY The price of the Company's stock, like that of other biotechnology companies, is subject to significant volatility. Any number of events, both internal and external to the Company, may affect the stock price. These include, without limitation, results of clinical trials conducted by the Company or by its competitors; announcements by the Company or its competitors regarding product development efforts, including the status of regulatory approval applications; the outcome of legal proceedings, including claims filed by the Company against third parties to enforce its patents and claims filed by third parties against the Company relating to patents held by the third parties; the launch of competing products; the resolution of (or failure to resolve) disputes with collaboration partners; corporate restructuring by the Company; licensing activities by the Company; and the acquisition or sale by the Company of products, products in development or businesses. In connection with its research and development collaborations, from time to time the Company invests in equity securities of its corporate partners. The price of these securities also is subject to significant volatility and may be affected by, among other things, the types of events that affect the Company's stock. Changes in the market price of these securities may impact the Company's profitability. TAXES The Company is taxable principally in the U.S., Germany, Italy and The Netherlands. All of these jurisdictions have in the past and may in the future make changes to their corporate tax rates and other tax laws, which could increase the Company's tax provision in the future. The Company has negotiated a number of rulings regarding income and other taxes that are subject to periodic review and renewal. If such rulings are not renewed or are substantially modified, taxes payable in particular jurisdictions could increase. While the Company believes that all material tax liabilities are properly reflected in its balance sheet, the Company is presently under audit in several jurisdictions, and there can be no assurance that Chiron will prevail in all cases in the event the taxing authorities disagree with its interpretations of the tax law. In addition, the Company has assumed liabilities for all income taxes incurred prior to the sales of its former subsidiaries, Chiron Vision Corporation (subject to certain limitations) and Chiron Diagnostics Corporation. Future levels of research and development spending, capital investment and export sales will impact the Company's entitlement to related tax credits and benefits, which have the effect of lowering its effective tax rate. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK FOREIGN CURRENCY RISK A significant portion of the Company's operations consists of manufacturing and sales activities in foreign countries exposing the Company to the effects of changes in foreign currency rates. The Company's primary exposure to foreign exchange rates is associated with the value of the Euro. An increase in the value of the U.S. Dollar vis-a-vis the Euro will result in a lower value of the Company's non-U.S. Dollar based revenues. To manage foreign currency exchange risks, Chiron enters into forward foreign currency contracts ("forwards") and cross currency interest rate swaps ("swaps") and purchases foreign currency option contracts ("options"). Chiron does not use any of these derivative instruments for trading or speculative purposes. The total notional principal amount of these derivative financial instruments at December 31, 1999 and 1998 was $254.1 million and $297.1 million, respectively. The Company uses forwards to hedge the impact of currency fluctuations on certain assets and liabilities denominated in nonfunctional currencies ("transaction exposures"). Typically, these contracts have maturities of three months or less. Chiron's objective is to minimize the transaction gains and losses recorded in current earnings that result from remeasuring foreign denominated assets and liabilities based on exchange rate fluctuations. The Company's transaction exposures are primarily denominated in major European currencies. At December 31, 1999, these exposures amounted to $51.7 million and were offset by forwards with a notional principal amount of $27.3 million (fair value of $27.2 million). Based on 32 exposures as of December 31, 1999, a 10% adverse movement against the Company's portfolio of transaction exposures and hedge contracts would result in a loss of approximately $2.6 million. A 10% movement in the value of the dollar versus the Company's portfolio of transaction exposures has occurred in 1 of the last 12 quarters. Foreign currency transaction gains and losses from continuing operations, including the impact of hedging, were not significant in 1999, 1998 or 1997. Chiron may selectively hedge anticipated currency exposures by purchasing quarterly put options. The Company's primary anticipated exposures are related to intercompany inventory purchases by subsidiaries with functional currencies denominated in major European currencies, as well as foreign revenues received from selling products in the major European countries. To limit hedging costs, the Company generally purchases out-of-the-money put options. The Company had no option contracts outstanding at December 31, 1999. The total notional principal amount of the options at December 31, 1998 was $55.6 million (fair value of $0.3 million). Chiron's operational facilities in Europe have counterbalanced a portion of the anticipated exposures associated with European sales. The Company has entered into a series of swaps to modify the interest and/or currency characteristics of certain assets and liabilities denominated in nonfunctional currencies. The objective of the swaps entered into by the Company is to fix the interest and currency rate exposures associated with the Company's wholly-owned German subsidiary. The exposures are denominated in Deutsche marks. The notional principal amount of the Company's swaps at December 31, 1999 and 1998 was $226.8 million. If the Deutsche mark strengthened or weakened by 10%, the value of the underlying exposure would increase or decrease by $21.8 million and $17.8 million, respectively. After considering the impact of hedging with swaps, the net increase or decrease from such currency rate fluctuation would be reduced to $9.0 million and $7.3 million, respectively. A 10% movement in the value of the Deutsche mark versus the U.S. dollar has occurred in 4 of the last 10 years. The fair market value of the swaps is $23.6 million as of December 31, 1999. Currency fluctuations in the value of the German subsidiary's assets and liabilities, as well as changes in the value of related swaps, are reflected as a component of other comprehensive income or loss. INTEREST RATE RISK The Company has exposure to changes in interest rates in both its investment portfolio and certain floating rate liabilities and lease commitments with interest rates tied to LIBOR. The Company maintains investment portfolio holdings of various issuers, types and maturities. Changes in interest rates do not affect interest expense incurred on the Company's long-term debt because the Company's long-term debt issues bear interest at fixed rates. Chiron's investment portfolio amounted to approximately $1.6 billion at December 31, 1999. As of that date, the Company also had $240.4 million of floating rate debt tied to LIBOR. The Company has a "natural hedge" against this exposure as a result of its portfolio holdings in floating rate fixed income securities tied to LIBOR. The analysis below focuses on the impact of changes in interest rates to Chiron and is based on a net unhedged portfolio balance of $1.3 billion. The analysis assumes an immediate parallel increase or decrease in interest rates of 150-basis points and examines the impact to Chiron over the next twelve months. An immediate increase in interest rates of 150-basis points results in higher interest income over the 12-month period, partially offset by an immediate decline in the market value of securities held. The net impact of this scenario is an estimated increase in total return to the portfolio of $6.0 million over the 12-month period. Similarly, a 150-basis point decrease results in a decrease in total return to the portfolio of $5.8 million. The impact on reported earnings will be greater given that unrealized changes in the value of the portfolio are reported in other comprehensive income or loss. Chiron currently does not hedge these exposures. The effect of these changes in interest rates on the Company's portfolio, as measured over a 12-month period, are mitigated by the relatively short duration of Chiron's portfolio. 33 A 150-basis point movement in the Federal Funds rate has occurred in 3 of the last 10 years, a 100-basis point movement has occurred in 5 of the last 10 years, and a 50-basis point movement has occurred in 9 of the last 10 years. EQUITY SECURITIES RISK The Company has exposure to equity price risk because of its investments in equity securities. Typically, the Company obtains these securities through its collaboration agreements with other pharmaceutical and biotechnology partners. A majority of these securities are classified as available-for-sale and, consequently, are recorded on the balance sheet at fair value with unrealized gains or losses reported as a component of other comprehensive income or loss. Other-than-temporary losses are recorded against earnings in the same period the loss was deemed to have occurred. A portion of these securities are classified as trading and, consequently, are recorded on the balance sheet at fair value with unrealized gains and losses recorded in earnings. Changes in share prices or in the volatility of share prices affect the value of Chiron's equity portfolio. To reduce this risk, the Company has hedged a portion of its exposure through short sales. The short sales substantially offset the long position and, in effect, neutralize the impact of market valuation shifts on the hedged securities. The notional principal amount of the Company's short sales at December 31, 1999 was $4.5 million (fair value of $4.6 million). The Company had no short sales at December 31, 1998. In the future, the Company may use additional hedging strategies in order to mitigate the potential adverse impact from changes in the market value of stock prices. There can be no assurance that other-than-temporary losses will not have a material adverse impact on the Company's results of operations in the future. The Company recorded charges of $1.7 million, $8.4 million and $1.2 million in 1999, 1998 and 1997, respectively, to write down certain available-for-sale equity securities for which the decline in fair value was deemed to be other-than-temporary. As of December 31, 1999, if the market price of Chiron's equity investments, including warrants and preferred stock, decreased by 10%, the market value of the equity portfolio would decrease by $8.0 million. COUNTERPARTY RISK Chiron manages the risk of counterparty default on its derivative financial instruments through the use of credit standards, counterparty diversification and monitoring of counterparty financial condition. All derivative financial instruments are executed with financial institutions with strong credit ratings, which minimizes risk of loss due to nonpayment. Chiron has not experienced any losses due to counterparty default. ITEM 8.

In connection with our audits of the consolidated financial statements, we also have audited the financial statement schedule as listed in the accompanying index. These consolidated financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Chiron Corporation and subsidiaries as of December 31, 1999 and 1998, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 1999, in conformity with generally accepted accounting principles. Also in our opinion, the related consolidated financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein. /s/ KPMG LLP San Francisco, California January 31, 2000 F-1 CHIRON CORPORATION CONSOLIDATED BALANCE SHEETS (IN THOUSANDS, EXCEPT SHARE DATA) ASSETS DECEMBER 31, ----------------------- 1999 1998 ---------- ---------- Current assets: Cash and cash equivalents................................. $ 363,865 $ 513,315 Short-term investments in marketable debt securities...... 640,027 716,619 Short-term investments in equity securities............... 3,315 -- ---------- ---------- Total cash and short-term investments................... 1,007,207 1,229,934 Accounts receivable, net of allowances of $16,998 in 1999 and $18,160 in 1998: Related parties......................................... 23,117 49,256 Unrelated parties....................................... 138,766 118,332 ---------- ---------- 161,883 167,588 Current portion of note receivable........................ 3,233 -- Inventories............................................... 84,724 79,862 Other current assets: Related parties......................................... 1,160 245 Unrelated parties....................................... 81,093 153,313 ---------- ---------- 82,253 153,558 ---------- ---------- Total current assets.................................. 1,339,300 1,630,942 Noncurrent investments in marketable debt securities........ 547,580 360,069 Property, plant, equipment and leasehold improvements, at cost: Land and buildings........................................ 132,861 141,452 Laboratory, production and office equipment............... 291,503 236,803 Leasehold improvements.................................... 73,143 84,607 Construction in progress.................................. 23,894 38,321 ---------- ---------- 521,401 501,183 Less accumulated depreciation and amortization............

F-8 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 1999 NOTE 1--THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES THE COMPANY AND BASIS OF PRESENTATION Chiron Corporation ("Chiron" or the "Company") is a biotechnology company that develops, manufactures and markets human healthcare products for the prevention and treatment of disease utilizing innovations in biology and chemistry. Chiron participates in three human healthcare businesses: (i) biopharmaceuticals, with an emphasis on cancer, infectious diseases and cardiovascular diseases; (ii) adult and pediatric vaccines; and (iii) blood testing. The Company is applying a broad and integrated scientific approach to the development of innovative products for preventing and treating cancer, infectious diseases and cardiovascular diseases. This approach is supported by research strengths in recombinant proteins, small molecules, genomics and vaccines. On December 29, 1997, Chiron completed the sale of its ophthalmics business, Chiron Vision Corporation ("Chiron Vision"), to Bausch & Lomb Incorporated ("B&L"), and on November 30, 1998, Chiron completed the sale of its IN VITRO diagnostics business ("Chiron Diagnostics") to Bayer Corporation ("Bayer") (see Note 4). As a result of these transactions, the Company's Consolidated Statements of Operations reflect the after-tax results of Chiron Vision and Chiron Diagnostics as discontinued operations for all periods presented. On March 31, 1998, in an acquisition accounted for under the purchase method of accounting, Chiron acquired the remaining 51% interest in Chiron Behring GmbH & Co ("Chiron Behring"), not previously owned, from Hoechst AG. Beginning in the second quarter of 1998, the results of Chiron Behring were consolidated with those of the Company (see Note 5). Prior to fiscal year 1999, the results of Chiron's Italian subsidiary ("Chiron S.p.A.") were reported on a one-month lag. In the first quarter of 1999, the results of Chiron S.p.A. were brought current. As a result, during fiscal year 1999, the Company recorded a loss of $5.2 million for the month of December 1998 as a component of "Accumulated deficit" in the Consolidated Balance Sheets. FISCAL YEAR Effective with the beginning of fiscal year 1999, the Company changed its fiscal year from a 52 or 53-week year ending on the Sunday nearest the last day in December to coincide with a calendar year ending on December 31. In 1998, the Company's fiscal year was a 53-week year ending on January 3, 1999, and in 1997, the Company's fiscal year was a 52-week year ending on December 28, 1997. For presentation purposes, dates used in the consolidated financial statements and notes thereto refer to the fiscal year end. PRINCIPLES OF CONSOLIDATION The accompanying consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Investments in joint ventures, partnerships and interests in which Chiron has an equity interest of 50% or less are accounted for using either the equity or cost method. Certain investments in affiliated companies are accounted for either on a one-month or one-quarter lag. USE OF ESTIMATES AND RECLASSIFICATIONS The preparation of financial statements in accordance with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the F-9 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 1--THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Company's consolidated financial statements and notes thereto. Actual results could differ materially from those estimates. The Consolidated Financial Statements for 1997 have been reclassified to separately identify the results of Chiron's discontinued operations. In addition, during 1999, the Company completed the implementation of an integrated information system. As a result, certain previously reported amounts have been reclassified to conform with the current period presentation. CASH EQUIVALENTS, INVESTMENTS IN MARKETABLE DEBT SECURITIES AND INVESTMENTS IN EQUITY SECURITIES All highly liquid investments with a maturity of three months or less from the date of purchase are considered to be cash equivalents. Cash equivalents and short-term investments in marketable debt securities consist principally of money market instruments, including corporate notes and bonds, commercial paper and government agency securities. Noncurrent investments in marketable debt securities consist principally of corporate notes and bonds and government agency securities. The cost of securities sold is based on the specific identification method for debt securities and on the average cost method for equity securities. In accordance with SFAS No. 115, "Accounting for Certain Investments in Debt and Equity Securities" ("SFAS 115"), the Company has classified its investments in certain equity securities as trading and in certain debt and equity securities as available-for-sale. Trading securities are recorded at fair value based upon year-end quoted market prices and unrealized gains and losses are included in results of operations. Available-for-sale securities are recorded at fair value based upon year-end quoted market prices and unrealized gains and losses, deemed by the Company as temporary in nature, are reported as a separate component of other comprehensive income or loss. INVENTORIES Inventories are stated at the lower of cost or market using the moving weighted-average cost method as of December 31, 1999. For the period ended December 31, 1998, Chiron S.p.A.'s vaccine inventories were valued using the last-in, first-out ("LIFO") method. In the second quarter of 1999, the Company changed its inventory valuation methodology for these vaccine inventories from LIFO to the moving weighted-average cost method. The effect of this change in methodology was not material to the financial statements. Inventories consist of the following at December 31: 1999 1998 -------- -------- (IN THOUSANDS) Finished goods............................................ $16,614 $12,301 Work in process........................................... 49,193 54,333 Raw materials............................................. 18,917 13,228 ------- ------- $84,724 $79,862 ======= ======= PROPERTY, PLANT, EQUIPMENT AND LEASEHOLD IMPROVEMENTS Property, plant, equipment and leasehold improvements are recorded at cost less accumulated depreciation. Depreciation on property, plant and equipment, including assets held under capital leases, is computed using the straight-line method over the estimated useful lives of the assets, ranging from 3 to 10 F-10 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 1--THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) years for equipment and 15 to 40 years for buildings. Leasehold improvements are amortized on a straight-line basis over the shorter of the asset's useful life or remaining lease term. INTANGIBLE AND OTHER LONG-LIVED ASSETS Intangible assets consist principally of purchased technologies, goodwill and patents and are amortized on a straight-line basis over their estimated useful lives, ranging from 3 to 20 years. Amortization expense for the years ended December 31, 1999, 1998 and 1997 was $17.3 million, $15.7 million and $7.0 million, respectively. Amortization of purchased technologies and goodwill is primarily included in "Other operating expenses" and amortization of patents is primarily included in "Research and development" in the Consolidated Statements of Operations. As circumstances dictate, the Company assesses the recoverability of its intangible and other long-lived assets by comparing the projected undiscounted net cash flows associated with such assets against their respective carrying values. Impairment, if any, is based on the excess of the carrying value over the fair value. TREASURY STOCK Treasury stock is stated at cost. Gains on reissuance of treasury stock are credited to additional paid-in capital. Losses on reissuance of treasury stock are charged to additional paid-in capital to the extent of available net gains on reissuance of treasury stock. Otherwise, losses are charged to accumulated deficit. For the year ended December 31, 1999, the Company charged losses of $40.5 million to accumulated deficit. REVENUE RECOGNITION "Product sales, net" primarily consist of revenues from product shipments. For sales of Betaseron-Registered Trademark-(interferon beta-1b), the Company recognizes revenues upon shipment to its marketing partner and additional revenues upon the marketing partner's subsequent sale of Betaseron-Registered Trademark- to patients. Beginning in July 1997, the contractual terms under which Chiron recognizes Betaseron-Registered Trademark- revenues changed, with a larger portion of revenues recognized when the marketing partner realizes sales, rather than upon Chiron's initial shipment. "Equity in earnings of unconsolidated joint businesses" represents the Company's share of the operating results generated by its commercial unincorporated joint businesses. "Collaborative agreement revenues" are earned and recognized based upon work performed or upon the attainment of specified milestones. Under contracts where reimbursement is based upon work performed, the related research and development expenses were $49.7 million, $61.9 million and $79.5 million in 1999, 1998 and 1997, respectively. "Royalty and license fee revenues" consist of product royalty payments and fees under license agreements and are recognized when earned. Nonrefundable fees associated with royalty and license arrangements where the Company has no continuing performance obligations are recognized in income when received. In situations where continuing performance obligations exist, up-front nonrefundable fees are deferred and amortized over the performance period. Milestones, if any, related to scientific achievement are recognized in income when the milestone is accomplished. "Other revenues" consist primarily of fees for sales and marketing services performed, commission fees and grants from government agencies and are recognized when earned. In 1997, "Other revenues" also included revenue related to Chiron's co- F-11 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 1--THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) promotion of Novartis AG's product, Aredia-Registered Trademark-, which was recognized, in part, based on the percentage of effort expended. CONTRACT MANUFACTURING REVENUES AND EXPENSES Contract manufacturing revenues are recognized upon completion of the specified contract milestones and are recorded in "Other revenues" in the Consolidated Statements of Operations. Contract manufacturing expenses are expensed as incurred and are recorded in "Other operating expenses" in the Consolidated Statements of Operations. RESEARCH AND DEVELOPMENT EXPENSE AND WRITE-OFF OF PURCHASED IN-PROCESS TECHNOLOGIES In accordance with Statement of Financial Accounting Standards ("SFAS") No. 2, "Accounting for Research and Development Costs" ("SFAS 2"), research and development costs are charged to expense when incurred. Purchased in-process technologies represent the value assigned or paid for acquired research and development for which there is no alternative future use as of the date of acquisition. In accordance with SFAS 2, as clarified by FASB Interpretation No. 4, amounts assigned to purchased in-process technologies meeting the above stated criteria are charged to expense as part of the allocation of the purchase price of the business combination. ADVERTISING EXPENSES The Company expenses the costs of advertising, including promotional expenses, as incurred. Advertising expenses for the years ended December 31, 1999, 1998 and 1997 were $10.0 million, $12.2 million and $7.1 million, respectively. INCOME TAXES Income taxes are accounted for under the asset and liability method. 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 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 income in the period that includes the enactment date. No provision is made for U.S. income taxes applicable to undistributed earnings of foreign subsidiaries that are indefinitely reinvested in foreign operations. STOCK-BASED COMPENSATION As permitted by SFAS No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"), the Company measures compensation expense for its stock-based employee compensation plans using the intrinsic method prescribed by Accounting Principles Board ("APB") No. 25, "Accounting for Stock Issued to Employees" ("APB 25"). In accordance with SFAS 123, the Company has provided in Note 12 the pro forma disclosures of the effect on net income and earnings per common share as if SFAS 123 had been applied in measuring compensation expense for all periods presented. F-12 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 1--THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) FOREIGN CURRENCY TRANSLATION The financial statements of the Company's foreign subsidiaries and equity investments are generally measured using the local currency as the functional currency. Accordingly, the assets and liabilities of the Company's foreign subsidiaries and equity investments are translated into U.S. dollars using the exchange rates in effect at the end of the period. Revenues and expenses are translated using the average exchange rates for the period. Adjustments resulting from currency translations are included in "Other comprehensive income (loss)." Gains and losses resulting from currency transactions are recognized in current operations. DERIVATIVE FINANCIAL INSTRUMENTS The Company utilizes derivative financial instruments, including forward foreign currency contracts, foreign currency option contracts and cross currency interest rate swaps, to reduce foreign exchange and interest rate risks. The Company also uses short sales to reduce equity securities risk. Derivative financial instruments are not used for trading or speculative purposes. The Company's control environment includes policies and procedures for risk assessment and the approval, reporting and monitoring of foreign currency hedging activities. Counterparties to the Company's hedging agreements are major financial institutions. The Company manages the risk of counterparty default on its derivative financial instruments through the use of credit standards, counterparty diversification and monitoring of counterparty financial conditions. Chiron has not experienced any losses due to counterparty default. CONCENTRATION OF CREDIT RISK Financial instruments, which potentially expose the Company to concentrations of credit risk, consist primarily of cash, investments and trade accounts receivable. The Company invests cash, which is not required for immediate operating needs, in a diversified portfolio of financial instruments issued by financial institutions of high credit standing. By policy, the amount of credit exposure to any one institution is limited. These investments are generally not collateralized and primarily mature within three years. The Company has not realized any significant losses on these investments. The Company has not experienced any significant credit losses from its accounts receivable from joint business partners or collaborative research agreements, and none are currently expected. Other accounts receivable arise from product sales to customers. The Company performs ongoing credit evaluations of these customers and generally does not require collateral. The Company maintains reserves for potential trade receivable credit losses, and such losses have been within management's expectations. COMPREHENSIVE INCOME In accordance with SFAS No. 130, "Reporting Comprehensive Income" ("SFAS 130"), the Company has displayed the components of "Other comprehensive income (loss)" and "Comprehensive income" in the Consolidated Statements of Comprehensive Income. No tax effect has been provided on the foreign currency translation component for any period as the undistributed earnings of the Company's foreign investments are expected to be continually reinvested. F-13 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 2--EARNINGS PER COMMON SHARE Basic earnings per common share is based upon the weighted-average number of common shares outstanding. Diluted earnings per common share is based upon the weighted-average number of common shares and dilutive potential common shares outstanding. Dilutive potential common shares could result from (i) the assumed exercise of outstanding stock options, warrants and equivalents, which are included under the treasury-stock method; (ii) performance units (see Note 12) to the extent that dilutive shares are assumed issuable; and (iii) convertible subordinated debentures, which are included under the if-converted method. The following table sets forth the computation for basic and diluted earnings per common share on income from continuing operations for the years ended December 31: 1999 1998 1997 ----------- ----------- ----------- (IN THOUSANDS, EXCEPT PER SHARE DATA) Income (Numerator): Income from continuing operations available to common stockholders.............................................. $128,404 $ 75,998 $ 25,782 Plus: Interest on 1.9% convertible debentures, net of taxes..................................................... 1,936 -- -- -------- -------- -------- Income available to common stockholders, plus assumed conversions............................................... $130,340 $ 75,998 $ 25,782 -------- -------- -------- Shares (Denominator): Weighted-average common shares outstanding.................. 181,162 177,587 173,524 Effect of dilutive securities: Options and equivalents..................................... 4,279 2,956 4,219 Warrants.................................................... 288 190 204 Performance units........................................... -- -- 41 1.9% convertible debentures................................. 2,196 -- -- -------- -------- -------- Weighted-average common shares outstanding, plus assumed conversions............................................... 187,925 180,733 177,988 -------- -------- -------- Basic earnings per common share............................. $ 0.71 $ 0.43 $ 0.15 ======== ======== ======== Diluted earnings per common share........................... $ 0.69 $ 0.42 $ 0.14 ======== ======== ======== F-14 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 2--EARNINGS PER COMMON SHARE (CONTINUED) The following table sets forth the computation for basic and diluted earnings per common share on net income for the years ended December 31: 1999 1998 1997 ----------- ----------- ----------- (IN THOUSANDS, EXCEPT PER SHARE DATA) Income (Numerator): Net income available to common stockholders................. $160,577 $524,113 $ 71,219 Plus: Interest on 1.9% convertible debentures, net of taxes..................................................... 1,936 -- -- -------- -------- -------- Income available to common stockholders, plus assumed conversions............................................... $162,513 $524,113 $ 71,219 -------- -------- -------- Shares (Denominator): Weighted-average common shares outstanding.................. 181,162 177,587 173,524 Effect of dilutive securities: Options and equivalents..................................... 4,279 2,956 4,219 Warrants.................................................... 288 190 204 Performance units........................................... -- -- 41 1.9% convertible debentures................................. 2,196 -- -- -------- -------- -------- Weighted-average common shares outstanding, plus assumed conversions............................................... 187,925 180,733 177,988 -------- -------- -------- Basic earnings per common share............................. $ 0.89 $ 2.95 $ 0.41 ======== ======== ======== Diluted earnings per common share........................... $ 0.86 $ 2.90 $ 0.40 ======== ======== ======== Options to purchase 6.0 million shares, 10.1 million shares and 7.8 million shares with exercise prices greater than the average market prices of common stock were outstanding during the years ended December 31, 1999, 1998 and 1997, respectively. These options were excluded from the respective computations of diluted earnings per share as their inclusion would be antidilutive. Also excluded from the computations of diluted earnings per share were 9.8 million shares, 12.0 million shares and 12.0 million shares for the years ended December 31, 1999, 1998 and 1997, respectively, of common stock issuable upon conversion of the Company's convertible subordinated debentures (see Note 10) as the interest, net of tax, per common share obtainable on conversion exceeds basic earnings per share.

The sale was completed under the terms of a Stock Purchase Agreement (the "Bayer Agreement"), dated as of September 17, 1998, between Chiron and Bayer. The results of operations for Chiron Diagnostics are reported as a discontinued operation for all periods presented in the Consolidated Statements of Operations. Chiron has provided customary indemnities under the terms of the Bayer Agreement. In connection with the sale of Chiron Diagnostics, Chiron granted to Chiron Diagnostics rights under certain Chiron patents, including non-exclusive rights to patents relating to human immunodeficiency virus ("HIV") and hepatitis C virus ("HCV"). In exchange for these rights, Chiron Diagnostics paid to Chiron $100.0 million, which is refundable in decreasing amounts through 2001. In 1999 and 1998, Chiron recognized revenues of $39.2 million and $13.3 million, respectively, which represent the portions of the $100.0 million payment which became nonrefundable during those periods. The revenues were recorded as a component of "Royalty and license fee revenues" in the Consolidated Statements of Operations. The Company anticipates recognizing the remaining revenue as follows: $29.2 million in 2000 and $18.3 million in 2001. As a result of the sale of Chiron Diagnostics, the Company assigned certain technology rights, which it had utilized in its blood testing and diagnostics businesses, to Bayer. The assigned rights, which had been capitalized as intangible assets and had a net book value of $9.5 million at the time of assignment, were expensed against the "Gain on disposal of discontinued operations" in 1998. Under the terms of the Agreement, Chiron and Bayer agreed to share certain future milestone payments related to these technology rights. Accordingly, Chiron made a milestone payment of $8.5 million in December 1999. Since the Company received regulatory approval in France for the transcription-mediated amplification ("TMA") combination HCV/HIV-I test in September 1999, the Company ascertained that there is future value in these technology rights and, therefore, has capitalized the related milestone payment of $8.5 million, to be amortized over 5 years. F-16 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 4--DISCONTINUED OPERATIONS (CONTINUED) On December 29, 1997, Chiron completed the sale of all of the outstanding capital stock of Chiron Vision to B&L for approximately $300.0 million in cash, subject to certain post-closing adjustments. The sale was completed under the terms of a Stock Purchase Agreement (the "B&L Agreement"), dated as of October 21, 1997, between Chiron and B&L. Chiron Vision's cash and cash equivalents totaling $2.7 million, certain Chiron Vision real estate assets (the "real estate assets") with a carrying value of $25.1 million and Chiron Vision's future noncancelable operating lease costs totaling $1.1 million were retained by the Company upon the completion of the sale. The Company has provided customary indemnities under the terms of the B&L Agreement. In 1999, the Company reversed approximately $8.3 million reserved for contractual obligations to indemnify B&L against certain potential claims, as such obligations had expired. This was recorded as a component of "Gain on disposal of discontinued operations." For a period of three years following the completion of the sale, Chiron Vision has the right to use a portion of the real estate assets, which were occupied at closing, on a rent-free basis. As of December 31, 1999 and 1998, the real estate assets of $1.9 million and $11.5 million, respectively, which represent all of the remaining net assets of Chiron's discontinued operations, are recorded in the Consolidated Balance Sheets as "Other current assets." In July 1999, the Company recognized a gain of $4.8 million, which included a net income tax benefit of $2.9 million related to cumulative differences in the basis of the assets sold, upon sale of a portion of these real estate assets. This gain is recorded as a component of "Gain on disposal of discontinued operations." In connection with the sale of Chiron Diagnostics and Chiron Vision, the Company recorded cumulative net deferred tax assets of $26.0 million and $20.0 million in 1999 and 1998, respectively, principally attributable to the timing of the deduction of certain expenses associated with these sales. The Company also recorded corresponding valuation allowances of $26.0 million and $20.0 million in 1999 and 1998, respectively, to offset these deferred tax assets, as management does not believe that it is more likely than not that the deferred tax assets to which the valuation allowance relates will be realized. The future recognition of these deferred tax assets will be reported as a component of "Gain on disposal of discontinued operations." Prior to the sale of Chiron Diagnostics in 1998, Chiron reduced its valuation allowance related to Chiron Diagnostics' domestic and foreign deferred tax assets by $45.5 million, as the sale to Bayer in 1998 made it more likely than not that these deferred tax assets would be realized. Included in this amount was $3.7 million of foreign deferred tax assets recognized in accordance with Emerging Issues Task Force ("EITF") Issue No. 93-17, "Recognition of Deferred Tax Assets for a Parent Company's Excess Tax Basis in the Stock of a Subsidiary That is Accounted for as a Discontinued Operation" ("EITF 93-17"). In 1998, Chiron Diagnostics recognized total revenues of $527.7 million. In 1997, Chiron Diagnostics and Chiron Vision, collectively, recognized total revenues of $800.2 million. "Income from discontinued operations" in the Consolidated Statements of Operations was reported net of income tax provisions of $0.1 million and $2.9 million in 1998 and 1997, respectively. In addition, included in "Income from discontinued operations" was approximately $16.4 million of net income recognized by Chiron Diagnostics from September 17, 1998 to November 30, 1998 and $3.8 million of net income recognized by Chiron Vision from October 21, 1997 to December 28, 1997. "Gain on disposal of discontinued operations" in the Consolidated Statements of Operations included the sale of the real estate assets and an income tax benefit (provision) of $20.4 million, $(200.7) million and $15.2 million for the years ended December 31, 1999, 1998 and 1997, respectively. F-17 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 4--DISCONTINUED OPERATIONS (CONTINUED) Basic earnings per common share from discontinued operations was $0.18, $2.52 and $0.26 for the years ended December 31, 1999, 1998 and 1997, respectively. Diluted earnings per common share from discontinued operations was $0.17, $2.48 and $0.26 for the years ended December 31, 1999, 1998 and 1997, respectively. NOTE 5--ACQUISITION OF CHIRON BEHRING Effective July 1, 1996, Chiron purchased a 49% interest in the human vaccine business of Behringwerke AG, a subsidiary of Hoechst AG. The total acquisition price, which was paid in cash, was approximately $120.0 million, including costs directly related to the acquisition. Of the acquisition price, approximately $97.0 million was allocated to various intangible assets, such as goodwill, trademarks and patents, and is being amortized on a straight-line basis over lives ranging from 5 to 20 years. From July 1, 1996 through March 31, 1998 (period of joint ownership), Chiron and Hoechst AG operated the vaccine business as a joint venture under the name Chiron Behring GmbH & Co. Chiron accounted for its 49% interest under the equity method and recognized revenues of $2.4 million and $13.8 million as components of "Equity in earnings of unconsolidated joint businesses" in the Consolidated Statements of Operations for the years ended December 31, 1998 and 1997, respectively. In the second quarter of 1998, in an acquisition accounted for under the purchase method of accounting, Chiron acquired the remaining 51% interest in Chiron Behring from Hoechst AG. The purchase price of approximately $113.1 million, including acquisition costs, was allocated to the acquired assets and liabilities assumed based upon their estimated fair value on the date of acquisition. In connection with the acquisition, liabilities assumed were as follows: (IN THOUSANDS) Cash acquired............................................... $ 57,119 Fair value of all other assets acquired..................... 206,922 Carrying value of original investment in Chiron Behring..... (117,157) Cash paid................................................... (111,889) Acquisition costs........................................... (1,180) --------- Liabilities assumed......................................... $ 33,815 ========= At the time of acquisition, Chiron expensed $1.6 million of purchased in-process technologies. Other purchased intangible assets of approximately $135.0 million, including goodwill, trademarks, patents and customer list, are being amortized over their estimated useful lives of 4 to 17 years on a straight-line basis. Chiron Behring's operating results were included in Chiron's consolidated operating results beginning in the second quarter of 1998. The following unaudited pro forma information presents the results of continuing operations of Chiron and Chiron Behring for the years ended December 31, 1998 and 1997, respectively, with pro forma adjustments as if Chiron's acquisition of the remaining 51% interest in Chiron Behring had been consummated as of January 1, 1997. The pro forma information does not purport to be indicative of what F-18 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 5--ACQUISITION OF CHIRON BEHRING (CONTINUED) would have occurred had the acquisition been made as of those dates or of results that may occur in the future. The unaudited pro forma information is as follows: 1998 1997 --------- --------- (IN THOUSANDS, EXCEPT PER SHARE DATA) (UNAUDITED) Total revenues.......................................... $770,634 $733,855 Income from continuing operations....................... $ 78,128 $ 34,282 Pro forma earnings per common share from continuing operations: Basic................................................. $ 0.44 $ 0.20 Diluted............................................... $ 0.43 $ 0.19 NOTE 6--RESTRUCTURING AND REORGANIZATION CHARGES In 1999 and 1998, the Company recorded restructuring and reorganization charges related to the integration of its worldwide vaccines operations, the closure of its Puerto Rico and St. Louis, Missouri facilities and the ongoing rationalization of its business operations. The integration of its worldwide vaccines operations consisted of termination and other employee-related costs recognized in connection with the elimination of 28 positions in the Company's Italian manufacturing facility and facility-related costs. The closure of its Puerto Rico and St. Louis facilities and the ongoing rationalization of its business operations consisted of termination and other employee-related costs recognized in connection with the elimination of 400 positions in manufacturing, research and development, sales, marketing, and other administrative functions, and facility-related costs. During 1999, the Company decided to retain 18 of those 400 positions to support future contract manufacturing activities and, therefore, adjusted the number of positions for elimination to 382. Included in this amount were 36 positions at the Company's Amsterdam facility. These positions were transferred to the buyer in January 2000 (see Note 8). For the year ended December 31, 1999, the Company recorded restructuring and reorganization expenses of $0.2 million, which included a charge of $3.9 million and a benefit of $3.7 million. The charge of $3.9 million primarily related to termination and other employee-related costs recognized in connection with the elimination of 28 positions at the Company's Italian manufacturing facility. As of December 31, 1999, 24 of these 28 positions had been eliminated. The benefit of $3.7 million related to revised estimates of property-related accruals recorded in connection with the Company's ongoing rationalization of its business operations and the idling of the St. Louis facility, as well as revised estimates of termination and other employee-related costs recorded in connection with the elimination of 382 positions. As of December 31, 1999, 319 of these 382 positions had been eliminated. For the year ended December 31, 1998, the Company recorded net restructuring and reorganization charges of $26.8 million related to the integration of its worldwide vaccines operations, the closure of its Puerto Rico and St. Louis facilities and the ongoing rationalization of its business operations. Included in "Gain on disposal of discontinued operations" in the Consolidated Statements of Operations were restructuring and reorganization charges of $19.1 million and $3.3 million in 1998 and 1997, respectively. These charges related to the rationalization of the Company's IN VITRO diagnostics F-19 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 6--RESTRUCTURING AND REORGANIZATION CHARGES (CONTINUED) business operations and primarily consisted of employee termination costs related to the termination of 331 employees, all of which were terminated as of December 31, 1998.

NOTE 7--RESEARCH AND DEVELOPMENT ARRANGEMENTS Chiron participates in a number of research and development arrangements with other pharmaceutical and biotechnology companies to develop and market certain technologies and products. Chiron and its collaborative partners generally contribute certain technologies and research efforts and commit, subject to certain limitations and cancellation clauses, to share costs related to certain research and development activities, including those related to clinical trials. Chiron may also be required to make payments to certain collaborative partners upon their achievement of specified milestones. Aggregate annual funding commitments under collaborative arrangements are as follows: 2000--$11.1 million; 2001--$2.5 million; 2002--$1.3 million; 2003--$0.3 million; and 2004--$0.3 million. In connection with certain research and development arrangements, the Company may invest in equity securities of its collaborative partners. The price of these securities is subject to significant volatility. In 1999, 1998 and 1997, Chiron recognized losses of $1.7 million, $8.4 million and $1.2 million, respectively, attributable to the other-than-temporary impairment of certain of these equity securities. On April 1, 1999, the Company received a $9.7 million promissory note in consideration for payment under a biopharmaceutical collaboration agreement. The note bears interest at LIBOR plus 3% (9.0% at December 31, 1999). The interest is due quarterly and the principal is due in three equal installments, which are payable on June 30, 2000, June 30, 2001 and June 30, 2002. The Company recorded $3.2 million as "Current portion of note receivable" and $6.5 million as "Notes receivable" in the Consolidated Balance Sheets. The note is collateralized by the payor's right, title and interest in all amounts payable by the Company under the biopharmaceutical collaboration agreement. F-20 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 7--RESEARCH AND DEVELOPMENT ARRANGEMENTS (CONTINUED) On November 1, 1999, the Company entered into a patent and license agreement. Under this agreement, the Company paid $5.0 million of license fees, which were recorded as "Research and development" in the Consolidated Statements of Operations, and advanced $7.5 million in return for a promissory note, which was recorded as "Note receivables" in the Consolidated Balance Sheets. The note bears interest at the prime rate (8.5% at December 31, 1999), is due with accrued interest on December 31, 2006 and will be forgiven (principal and accrued interest) if the U.S. Food and Drug Administration ("FDA") approves any product covered by the patent and license agreement for marketing in the U.S. prior to December 31, 2006. The Company may pay additional milestone payments if certain development objectives are met. In addition, the Company will pay royalties on future net product sales of the product under the patent and license agreement. NOTE 8--RELATED PARTY TRANSACTIONS AND JOINT BUSINESS ARRANGEMENT NOVARTIS AG The Company has an alliance with Novartis AG ("Novartis"), a life sciences company headquartered in Basel, Switzerland. Novartis was formed as a result of a December 1996 merger between Ciba-Geigy Limited ("Ciba") and Sandoz Limited. Under a series of agreements between Chiron and Novartis, effective January 1995, Novartis increased its ownership interest in the Company to 49.9%. As a result of subsequent stock issuances by the Company, Novartis' ownership interest in Chiron has been reduced to approximately 44% as of December 31, 1999. In January 1995, Chiron and Novartis entered into a Governance Agreement whereby Novartis agreed not to increase its ownership interest in the Company above 55% unless it acquires all of Chiron's outstanding capital stock in a "buy-out transaction." Such buy-out transaction cannot occur before January 5, 2001. Novartis may exceed these standstill amounts and increase its ownership interest up to 79.9% if the transaction is approved by a majority of the independent members of Chiron's Board of Directors. Under the terms of the Governance Agreement, Novartis is permitted to designate three members of Chiron's Board of Directors. In December 1995, Chiron and Novartis entered into a Limited Liability Company agreement (the "R&D Funding Agreement"). Under the terms of this agreement, Novartis agreed to fund certain research and development projects, including certain adult and pediatric vaccines and Insulin-Like Growth Factor-I ("IGF-I"). In December 1997, this agreement was amended to include research and development activities related to Factor VIII gene therapy and Herpes Simplex Virus-thymidine kinase ("HSV-tk"). This agreement provides that, through December 31, 2000, at Chiron's request, Novartis will fund up to 100% of the development costs incurred between January 1, 1995 and December 31, 1999 on these projects. The amount of funding that Novartis is obligated to provide is subject to an aggregate limit of $265.0 million. Under this agreement, in 1999, 1998 and 1997, Chiron recognized collaborative agreement revenues of $46.2 million, $54.4 million and $53.3 million, respectively. In 2000, the amount of R&D funding provided by Novartis is limited to $12.1 million. In consideration of the funding provided by Novartis under the R&D Funding Agreement, Novartis has an interest in a stream of variable royalties in future worldwide sales from certain adult and pediatric vaccines, IGF-I, Factor VIII and HSV-tk (the "Products"), if any, which are successfully developed. Novartis also has co-promotional rights, in countries other than in North America and Europe, for certain F-21 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 8--RELATED PARTY TRANSACTIONS AND JOINT BUSINESS ARRANGEMENT (CONTINUED) adult vaccines. Royalties on all specified products will be paid for a minimum of 10 years from the later of October 1, 2001 or the date of the first commercial sale of individual products covered by the R&D Funding Agreement, as amended. Chiron has the right, but not the obligation, to buy-out Novartis' interests in the Products for a price equal to the aggregate amount of R&D funding provided by Novartis, less any payments to or profits earned by Novartis in connection with the Products, plus interest at the London Interbank Offered Rate ("LIBOR"). Chiron must notify Novartis by January 1, 2002 as to whether it will exercise its buy-out right and will have until January 1, 2005 to tender the purchase price for the buy-out. Under the terms of an Investment Agreement, Novartis agreed to guarantee certain obligations of the Company under one or more revolving credit facilities through January 1, 2008. The principal amount of indebtedness under the guaranteed credit facilities may not exceed $402.5 million. In November 1996, Chiron and Novartis agreed that Chiron could increase the maximum borrowing amount under the guaranteed credit facilities by up to $300.0 million. In exchange for this increase, the amount of Chiron's common stock required to be purchased by a Novartis affiliate (at Chiron's request) would be reduced by an equal amount. Under the Investment Agreement, Novartis had guaranteed $172.6 million of Chiron's operating lease commitments as of December 31, 1999 (see Note 11). In connection with the sale of Chiron Diagnostics to Bayer, a promissory note owed by Chiron Diagnostics to Novartis was transferred to and assumed by the Company. The note payable to Novartis bears interest at a variable rate based on LIBOR (approximately 5.7% and 5.6% at December 31, 1999 and 1998, respectively). As of December 31, 1999 and 1998, the outstanding amount was $67.8 million and $63.9 million, respectively, including accrued interest. The note and accrued interest were paid in full on January 4, 2000. Under the terms of a November 1995 agreement with Novartis, Novartis agreed to pay $26.0 million over a five-year period, subject to certain adjustments, in exchange for a non-exclusive license to utilize Chiron's combinatorial chemistry techniques. In addition, the parties agreed to collaborate to utilize combinatorial chemistry technology to identify potential products in selected target areas. The agreement provides for research funding by Novartis and certain upfront milestone and royalty payments, as well as product commercialization rights for both parties. In connection with this agreement, Chiron recognized collaborative agreement revenues of $4.2 million, $6.0 million and $10.2 million in 1999, 1998 and 1997, respectively. In November 1996, in connection with the U.S. Federal Trade Commission's review of the merger between Ciba and Sandoz Limited, which created Novartis, Chiron and Novartis entered into a consent order pursuant to which Chiron agreed to grant a royalty-bearing license to Rhone-Poulenc Rorer, Inc. under certain Chiron patents relating to the HSV-tk gene in the field of gene therapy. Chiron and Novartis entered into a separate agreement which provides, among other things, for certain cross licenses between Chiron and Novartis, and under which, beginning in 1997, Novartis agreed to pay Chiron up to $60.0 million over five years. In connection with the agreement, Chiron recognized collaborative agreement revenues of $10.0 million in 1999 and $15.0 million in both 1998 and 1997. F-22 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 8--RELATED PARTY TRANSACTIONS AND JOINT BUSINESS ARRANGEMENT (CONTINUED) In December 1999, the Company sold certain assets that it had developed or acquired in connection with its research and development of a Cytomegalovirus ("CMV") vaccine to Aventis Pasteur (formerly Pasteur Merieux Connaught) for $10.0 million and licensed certain technology to Aventis Pasteur for use in connection with the CMV vaccine. The sale of these assets resulted in a gain of $7.5 million, which was included in "Gain on sale of intangible assets" in the Consolidated Statement of Operations. Under the terms of the agreements, in the event Aventis Pasteur successfully develops a CMV vaccine, it will pay the Company royalties on net sales of such vaccine and will grant the Company marketing rights to such vaccine in Germany and Italy. Novartis had provided research funding for the Company's CMV vaccine research and development program. In connection with this sale, Novartis waived its co-promotion rights for the CMV vaccine in return for royalties equal to 25% of fees and royalties received by the Company related to the CMV vaccines. At December 31, 1999, the Company recorded in "Accounts payable" in the Consolidated Balance Sheets an amount payable to Novartis of $2.5 million, which represents 25% of the Company's $10.0 million payment from Aventis Pasteur. From 1994 through April 1998, Chiron promoted Aredia-Registered Trademark- (pamidronate disodium for injection) on behalf of Novartis. In April 1998, the arrangement was terminated. In connection with the arrangement, in 1998 and 1997, Chiron recognized other revenues of $9.8 million and $43.6 million, respectively. LOAN TO EXECUTIVE OFFICER In June 1998, the Company provided a loan of $1.0 million to a senior executive officer. The loan, which is non-interest bearing, is secured by a primary deed of trust on real estate. Principal is payable in annual installments of $0.05 million over a period of ten years, with the outstanding principal balance due in full on June 22, 2008. As of December 31, 1999 and 1998, the amount outstanding on the loan was $0.9 million and $1.0 million, respectively. SALE OF THE AMSTERDAM MANUFACTURING FACILITY In December 1999, the Company sold its Amsterdam manufacturing facility and related machinery and equipment assets to Synco B.V., a company owned by a director of the Company, for $15.0 million in cash. The sale of the Amsterdam manufacturing facility resulted in a gain of $1.2 million, of which $0.9 million was included in "Gain on sale of assets" in the Consolidated Statements of Operations and $0.3 million was deferred as a result of the leaseback described below. The Company will amortize the unearned revenue as a reduction to rent expense over the lease term. The Company is leasing back office and warehouse space in the Amsterdam facility for some operational and administrative activities. The lease is a noncancelable operating lease, which expires in 2004 and may be extended for a period of two consecutive years (see Note 11). Annual rent is NLG 1.4 million ($0.6 million at December 31, 1999). At its option, the Company may lease certain equipment under the same terms as the office and warehouse lease. As of December 31, 1999, the Company had not exercised this option. Also, at the option of the new owner, the Company may provide various administrative services to the new owner. And, at the option of the Company, the new owner may provide various quality control services to the Company. As of December 31, 1999, no such services were being provided under these agreements. F-23 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 8--RELATED PARTY TRANSACTIONS AND JOINT BUSINESS ARRANGEMENT (CONTINUED) ORTHO-CLINICAL DIAGNOSTICS, INC. In 1989, Chiron entered into an agreement with Ortho-Clinical Diagnostics, Inc. ("Ortho"), a Johnson & Johnson ("J&J") company, to jointly develop, manufacture and market certain immunoassay diagnostic products. Under the terms of the agreement, Chiron receives 50% of the pretax operating profits of the joint business and is reimbursed for its continuing research, development and manufacturing costs. The joint business sells a full line of tests required to screen blood for hepatitis viruses and retroviruses and provides supplemental tests and microplate-based instrument systems to automate test performance and data collection. The joint business also holds the immunodiagnostic rights to Chiron's hepatitis and retrovirus technology and receives royalties from several companies, including Abbott Laboratories, Bio-Rad Laboratories, Inc. and Genelabs Diagnostic, Inc., for their sales of certain tests. Chiron records its share of profits from the Chiron-Ortho joint business on a one-month lag using estimates provided by Ortho. At the end of each year, the joint business records an annual inventory adjustment. Included in Chiron's share of the profits in 1999, 1998 and 1997 were annual inventory adjustments of $(0.7) million, $(4.1) million and $0.8 million, respectively. Profit sharing distributions are payable to Chiron within 90 days after the end of each quarter. At December 31, 1999 and 1998, $14.1 million and $22.1 million, respectively, were due from Ortho for profit sharing and reimbursement of costs. In 1999, 1998 and 1997, Chiron's 50% share of the profits from the joint business, which was recorded as a component of "Equity in earnings of unconsolidated joint businesses," was $78.1 million, $73.5 million and $92.9 million, respectively. Revenues recognized under the cost reimbursement portion of the agreement in 1999, 1998 and 1997 for product sales were $18.4 million, $20.6 million and $20.1 million, respectively, and for collaborative research were $8.3 million, $5.0 million and $7.1 million, respectively. NOTE 9--FAIR VALUE OF FINANCIAL INSTRUMENTS MARKETABLE SECURITIES At December 31, 1999, trading securities consisted of $3.3 million in equity securities and were classified as "Short term investments in equity securities" in the Consolidated Balance Sheets. For the year ended December 31, 1999, the Company recorded an unrealized gain of $3.3 million as part of "Other income, net" in the Consolidated Statements of Operations. The Company had no investments in equity securities classified as trading during 1998 and 1997.

Considerable judgment is required in interpreting market data to develop the estimates of fair value. As such, these estimated fair values are not necessarily indicative of the amounts that the Company could realize in a current market exchange. The fair value of nonmarketable equity investments that are accounted for under the cost method is based primarily on estimated market prices determined by a broker. The carrying values of variable rate notes receivable and notes payable approximate fair value due to the market-based nature of these instruments. The fair value of the deposits is based on the discounted value of expected future cash flows using current rates for assets with similar maturities. The fair value of the receivables from cross currency interest rate swaps is based on the discounted value of expected future cash flows using current rates. The fair value of convertible subordinated debentures is based on the market price at the close of business on the last day of the fiscal year. The fair values of the forward foreign currency contracts, the cross currency interest rate swaps and the short sales are based on estimated market prices, determined by a broker. Included in current assets and current liabilities are certain other financial instruments whose carrying values approximate fair value due to the short-term nature of such instruments. FOREIGN CURRENCY CONTRACTS A significant portion of the Company's operations consists of manufacturing and sales activities in western European countries. As a result, the Company's financial results may be affected by changes in the foreign currency exchange rates of those related countries. Forward foreign currency contracts ("forwards"), generally having average maturities of three months or less, are used to hedge material foreign currency denominated receivables and payables. Forwards are generally marked-to-market at the end of each quarter with gains or losses recorded as a component of "Other income, net" in the Consolidated Statements of Operations to offset gains or losses on foreign currency denominated receivables and payables. Outstanding notional principal amounts of the Company's forwards were $27.3 million and $14.7 million at December 31, 1999 and 1998, respectively. Foreign currency transaction gains and losses from continuing operations, net of the impact of hedging, were not significant in 1999, 1998 or 1997. The Company purchases foreign currency option contracts ("options") to reduce the exchange rate impact of a strengthening U.S. dollar on the underlying hedged amounts. These options are designated and effective as hedges of a portion of probable foreign currency exposure on anticipated intercompany inventory purchases over the next six months by subsidiaries with functional currencies other than the U.S. dollar. The cost of the options, which is recorded as a component of "Other current assets" in the Consolidated Balance Sheets, is deferred and amortized over the relevant term of the period hedged. The Company's financial exposure is limited to the amount paid for the options. Any resulting gains from these option contracts are deferred until the designated intercompany transactions are recorded and are recognized as a component of "Other income, net" in the Consolidated Statements of Operations. There were no options outstanding at December 31, 1999. Outstanding notional principal amounts of the Company's options were $55.6 million at December 31, 1998. F-26 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 9--FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED) CROSS CURRENCY INTEREST RATE SWAPS The Company selectively enters into cross currency interest rate swaps ("swaps") with major financial institutions to modify the interest and/or currency characteristics of certain assets and liabilities. These swap agreements involve the exchange of interest payments denominated in different currencies, based upon the terms described in the swap agreements. The net difference between the interest amounts paid and received is recognized as a component of "Other income, net" in the Consolidated Statements of Operations. The related interest amount payable or receivable from the major financial institutions is included as a component of other current liabilities or assets. Currency translation fluctuations in the underlying assets and liabilities, as well as changes in the value of the related swaps, are reflected in other comprehensive income or loss. Outstanding notional principal amounts of the Company's swaps were $226.8 million at December 31, 1999 and 1998, as described below. In April 1998, the Company entered into a series of swap agreements to fix the interest and currency exchange rate exposures associated with the Company's wholly-owned German subsidiary. The swaps mature in April 2003 and are based on an aggregate notional principal amount of $114.2 million. There is no exchange of principal amounts upon maturity. The agreements provide for quarterly interest payments based on a fixed Deutsche mark rate of 4.7% while receiving quarterly interest payments based on a fixed U.S. dollar rate of 4.8%. In July 1996, the Company also entered into swap agreements associated with the Company's wholly-owned German subsidiary that mature in July 2001 with an aggregate notional principal amount of $112.6 million. There is an exchange of principal amounts upon maturity. The Company effectively created a fixed rate Deutsche mark liability to fund certain Deutsche mark assets. The agreements provide for the Company to make quarterly interest payments based on a fixed Deutsche mark rate of 6.2% while receiving interest based on a variable rate tied to three-month U.S. dollar LIBOR plus 0.5% (6.3% and 5.8% at December 31, 1999 and 1998, respectively). SHORT SALES The Company selectively enters into short sales with major financial institutions. Short sales substantially offset long positions and, in effect, neutralize the impact of market valuation shifts on the hedged securities. Short sales are generally marked-to-market at the end of each quarter with gains or losses recorded in a manner consistent with the accounting for gains or losses on the underlying securities. In other words, if the underlying securities are classified as trading, the gain or loss on the short sales is recorded as a component of "Other income, net" in the Consolidated Statements of Operations. If the underlying securities are classified as available-for-sale, the gain or loss on short sales is recorded as a component of "Other comprehensive income (loss)" in the Consolidated Statements of Comprehensive Income. Outstanding notional principal amounts of the Company's short sales were $4.5 million at December 31, 1999, as described below. The Company had no short sales during 1998. In late December 1999, the Company entered into two short sales to hedge securities classified as trading and available-for-sale. The Company intends to cover in the near term the short position for the underlying securities classified as trading. The Company does not intend to cover in the near term the short position for the securities classified as available-for-sale. In addition, the Company entered into two margin account agreements in relation to the short sales. The agreements require the Company to deposit cash, in an amount equal to 50% of the market value of the hedged investments on the date of the short F-27 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 9--FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED) sales, into the margin accounts. Cash in the margin accounts earns interest at the prevailing market rate (5.0% at December 31, 1999) and is restricted for use until the short position is covered. At December 31, 1999, the Company had a cash balance of $2.2 million in the margin accounts, of which $1.1 million was recorded in "Other current assets" and $1.1 million was recorded in "Other assets" in the Consolidated Balance Sheets. The interest on this cash balance was not significant for the year ended December 31, 1999. NOTE 10--DEBT OBLIGATIONS AND CAPITAL LEASES Long-term debt consisted of the following at December 31: 1999 1998 --------- -------- (IN THOUSANDS) 1.9% convertible subordinated debentures............... $ 248,216 $242,074 5.25% convertible subordinated debentures.............. 94,994 92,996 Capital lease obligations.............................. -- 144 Other notes payable.................................... 3,282 4,596 --------- -------- 346,492 339,810 Less current portion................................... (249,534) (1,652) --------- -------- $ 96,958 $338,158 ========= ======== CONVERTIBLE SUBORDINATED DEBENTURES In 1993, Chiron issued 1.9% convertible subordinated debentures with a face value of $253.9 million and a yield to maturity of 4.5%. The notes are convertible, at the holders' option, into common stock at 34.6 shares per $1,000 principal amount and are due in November 2000. Interest is paid semi-annually. The Company may redeem the debentures at any time, at a redemption price starting at $905.78 per $1,000 principal amount, increasing to a redemption price equal to 100% of the principal amount at maturity. The debentures are carried net of an initial issue discount of $39.3 million, which is being accreted over the life of the debentures using the interest method. At December 31, 1999 and 1998, Novartis held debentures with a carrying value of $9.8 million and $9.6 million, respectively. As a result of the 1991 acquisition of Cetus Corporation ("Cetus"), the Company has outstanding 5.25% convertible subordinated debentures with a face value of $100.0 million. The notes are convertible at the holder's option at any time into common stock at 32.4 shares per $1,000 principal amount and are due in 2002. Interest is paid annually. At the option of the Company, the debentures may be redeemed at any time at face value. In 1991, these debentures were recorded at their then fair market value, which resulted in a discount of $20.0 million. This discount is being accreted over the life of the debentures using the interest method. CAPITAL LEASE OBLIGATIONS At December 31, 1999 and 1998, the gross book value of land, buildings and equipment leased under noncancelable capital leases, exclusive of amounts related to discontinued operations, totaled $3.3 million. F-28 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 10--DEBT OBLIGATIONS AND CAPITAL LEASES (CONTINUED) As of December 31, 1999, the assets leased under noncancelable capital leases were fully depreciated. As of December 31, 1998, accumulated depreciation totaled $2.8 million. OTHER NOTES PAYABLE The Company has various other notes payable with an average interest rate of 3.3% and 4.2% at December 31, 1999 and 1998, respectively. Maturities range from 2001 to 2003. Future maturities of other notes payable are as follows: 2000--$1.3 million, 2001--$1.9 million and $0.1 million thereafter. SHORT-TERM BORROWINGS Under a revolving, committed, unsecured credit agreement with a major financial institution, Chiron can borrow up to $100.0 million in the U.S. This credit facility is guaranteed by Novartis (refer to Note 8), provides various interest rate options and matures in February 2003. There were no borrowings outstanding under this credit facility at December 31, 1999. Additionally, the Company has credit facilities available outside the U.S. which allow for total borrowings of $63.1 million as of December 31, 1999. These revolving facilities are unsecured and are primarily maintained for Chiron's Italian subsidiary. At December 31, 1999, $20.3 million was outstanding under these credit facilities. In 1999 and 1998, the average interest rates on the outstanding borrowings related to continuing operations were approximately 3.6% and 4.4%, respectively. NOTE PAYABLE TO NOVARTIS At December 31, 1999 and 1998, the note payable to Novartis totaled $67.8 million and $63.9 million, respectively. It bears interest at a variable rate based on LIBOR (approximately 5.7% and 5.6% at December 31, 1999 and 1998, respectively). The note and accrued interest were paid in full on January 4, 2000. NOTE 11--COMMITMENTS AND CONTINGENCIES LEASES Chiron leases laboratory, office and manufacturing facilities, land and equipment under noncancelable operating leases, which expire through 2009. Rent expense from continuing operations was $24.6 million, $22.3 million and $12.3 million in 1999, 1998 and 1997, respectively. Future minimum lease payments under these leases are as follows: 2000--$24.9 million, 2001--$22.5 million, 2002--$20.8 million, 2003--$20.3 million, 2004--$13.0 million and thereafter--$28.8 million. Total future minimum rentals to be received under noncancelable subleases approximate $4.4 million as of December 31, 1999. In addition, in June 1996, the Company entered into a seven-year lease agreement with a group of financial institutions to rent a research and development facility, which was under construction until its completion in 1999. The total cost of the facility covered by this lease is $172.6 million. The lease provides for a substantial residual value guarantee in the event of market value declines, which is due upon termination of the lease in 2003. At the end of the lease, the Company can either exercise its purchase option or cause the facility to be sold to a third party. This lease is accounted for as an operating lease. The future minimum lease payments stated above exclude any payment related to this guarantee. As of December 31, 1999, Novartis had guaranteed $172.6 million of this lease commitment (see Note 8). F-29 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 11--COMMITMENTS AND CONTINGENCIES (CONTINUED) CETUS HEALTHCARE LIMITED PARTNERSHIPS In 1987 and 1990, Cetus and its affiliate, EuroCetus International N.V., exercised their options to repurchase all of the limited partnership interests in Cetus Healthcare Limited Partnership ("CHLP") and Cetus Healthcare Limited Partnership II ("CHLP II"). Under the CHLP purchase agreements, which expire on December 31, 2001, the Company is obligated to pay royalties on sales of certain therapeutic products in the U.S. and certain diagnostic products worldwide, as well as a portion of license, distribution or other fees with respect to such products, to the former limited partners of CHLP. Under the CHLP II purchase agreements, which expire on December 31, 2005, the Company is obligated to pay royalties and a portion of other income with respect to sales of certain products in Europe to the former limited partners of CHLP II. The Company is unable to estimate future costs subject to this obligation since these costs are based on future sales of products. OTHER COMMITMENTS Effective July 1, 1998, Chiron and International Business Machines Corporation ("IBM") executed a ten-year information technology services agreement. Under this agreement, IBM agreed to provide Chiron with a full range of information services. Chiron can terminate this agreement beginning July 1, 1999 subject to certain termination charges. If Chiron does not terminate this agreement, payments to IBM are expected to be approximately $111.8 million. Payments to IBM are subject to adjustment depending upon the levels of services and infrastructure equipment provided by IBM, as well as inflation. The Company has various firm purchase and capital project commitments totaling approximately $6.8 million at December 31, 1999. At December 31, 1999, the Company has $5.1 million outstanding under a letter of credit, which is required by German law, related to ongoing legal proceedings in Germany. The Company also has various performance bonds and insurance-related letters of credit in the amount of $4.9 million outstanding at December 31, 1999. NOTE 12--STOCKHOLDERS' EQUITY STOCK COMPENSATION PLANS At December 31, 1999, the Company has two stock-based compensation plans, which are described below. The Company applies APB 25 and related Interpretations in accounting for its plans for shares issued to employees. Accordingly, no compensation expense has been recognized for its stock-based compensation plans other than for performance-based awards and share rights. F-30 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 12--STOCKHOLDERS' EQUITY (CONTINUED) Had compensation cost for the Company's stock-based plans been determined based upon the fair value method prescribed under SFAS 123, the Company's net income and related net income per common share would have been reduced to the following pro forma amounts: 1999 1998 1997 -------- -------- -------- (IN THOUSANDS, EXCEPT PER SHARE DATA) Net income--basic: As reported.................................. $160,577 $524,113 $71,219 Pro forma.................................... $139,760 $500,681 $46,318 Net income--diluted As reported.................................. $162,513 $524,113 $71,219 Pro forma.................................... $141,696 $500,681 $46,318 Basic net income per common share: As reported.................................. $ 0.89 $ 2.95 $ 0.41 Pro forma.................................... $ 0.77 $ 2.82 $ 0.27 Diluted net income per common share: As reported.................................. $ 0.86 $ 2.90 $ 0.40 Pro forma.................................... $ 0.75 $ 2.77 $ 0.26 FIXED STOCK OPTION PLAN The Company's fixed stock option plan provides for the grant to employees of either nonqualified or incentive options and provides for the grant to directors, consultants and contractors of nonqualified options. Incentive options are to be granted at not less than the fair market value of common stock at the date of grant and nonqualified options at not less than 85% of such fair market value. Options are exercisable based on vesting terms determined by Chiron's Board of Directors (generally 4 years) and option terms cannot exceed ten years. At the annual meeting of stockholders in May 1997, the stockholders approved an amendment to the Company's stock option plan, increasing the maximum number of shares that may be issued by 13.0 million shares to 50.3 million shares. Of the 13.0 million share increase, 5.0 million shares were registered with the Securities and Exchange Commission in 1997. At December 31, 1999, 5.3 million shares were available for grant. F-31 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 12--STOCKHOLDERS' EQUITY (CONTINUED) A summary of stock option activity is as follows: 1999 1998 1997 ---------- ---------- ---------- Outstanding options at January 1,........................ 20,124,981 24,094,166 26,298,373 Granted................................................ 4,271,138 4,688,253 6,011,061 Forfeited..............................................

No dividends were factored into the calculation in 1999, 1998 or 1997. The following table summarizes information concerning outstanding and exercisable options at December 31, 1999: OPTIONS OUTSTANDING OPTIONS EXERCISABLE ----------------------------------------------- ---------------------------- WEIGHTED-AVERAGE WEIGHTED- WEIGHTED- NUMBER REMAINING AVERAGE NUMBER AVERAGE RANGE OF EXERCISE PRICES OUTSTANDING CONTRACTUAL LIFE EXERCISE PRICE OUTSTANDING EXERCISE PRICE - ------------------------ ----------- ---------------- -------------- ----------- -------------- Less than $15....................... 3,695,090 6.35 $14.31 2,852,544 $12.40 $15 to $19.......................... 4,181,912 5.97 17.75 3,183,855 17.40 $19 to $21.......................... 3,299,022 7.48 21.01 1,657,080 20.87 $21 to $23.......................... 2,463,894 7.50 22.44 1,477,854 22.36 $23 to $28.......................... 1,108,443 6.84 27.30 861,628 27.67 $28 to $32.......................... 2,371,779 9.67 31.88 749 31.88 Greater than $32.................... 108,050 7.75 39.60 200 37.64 ---------- ---- ------ ---------- ------ 17,228,190 7.14 $21.00 10,033,910 $18.17 ========== ========== In 1996, the stockholders approved an amendment to the Company's stock option plan, allowing certain executives to receive performance units. Performance units are stock awards for which vesting is contingent upon the attainment of certain pre-established performance goals over a specified period, as F-32 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 12--STOCKHOLDERS' EQUITY (CONTINUED) established by the Compensation Committee of the Board of Directors ("Compensation Committee"). Currently, the performance units are based on total shareholder return over a three-year period as measured against certain published benchmark indices that are representative of the Company's peer group. In order to qualify for a stock payout, Chiron's shareholder return must be within 15% of the three-year rolling weighted-average of the benchmark indices. In accordance with APB 25, compensation expense related to these awards is based on the extent to which the performance criteria are met. No such expense was recognized in 1999 or 1998. In 1997, the Company recognized $0.6 million of expense related to these performance units. There were no performance units awarded in 1999 or 1998. In 1997, the Company awarded performance units of 158,738 shares of common stock. No awards were exercisable at December 31, 1999. Pursuant to SFAS 123, the weighted-average fair value of the awards in 1997 was $6.71 per unit. The weighted-average fair value was based on the following assumptions: expected volatility of 37%; a risk-free interest rate of 6.0%; and an average expected life of 3 years. No dividends were factored into the calculation. In 1996, the stockholders also approved an amendment to the Company's stock option plan, permitting the award of share rights to certain key individuals and non-employee directors, allowing them the right to receive shares of the Company's common stock, subject to certain vesting terms. In 1999, the Compensation Committee awarded non-employee directors an aggregate of 11,098 share rights that vest over five years, and also awarded certain key individuals an aggregate of 228,175 share rights that vest over four years. In 1998, the Compensation Committee awarded non-employee directors an aggregate of 9,840 share rights that vest over five years, and also awarded certain key individuals an aggregate of 271,300 share rights that vest over four years. In 1997, the Compensation Committee awarded non-employee directors an aggregate of 12,043 share rights that vest over five years, and also awarded certain key individuals an aggregate of 319,700 share rights that vest over four years. The value of the share rights are recognized ratably over the related vesting periods and, in 1999, 1998 and 1997, the Company recognized $2.1 million, $2.4 million and $0.8 million of compensation expense, respectively. EMPLOYEE STOCK PURCHASE PLAN Chiron has a stock purchase plan for U.S. employees in which eligible employees may participate through payroll deductions. At the end of each quarter, funds deducted from participating employees' salaries are used to purchase common stock at 85% of the lower of market value at the quarterly purchase date or the employees' eligibility date for participation. Purchases of shares made under the plan were 0.4 million, 1.0 million and 1.4 million in 1999, 1998 and 1997, respectively. In 1997, the stockholders approved a new employee stock purchase plan which effectively replaced the existing plan which was to expire in March 1998. The terms and provisions of the new plan are substantially similar to those of Chiron's previous plan. Under the new plan, 8.2 million shares have been reserved for issuance, of which 0.6 million shares represent the remaining shares reserved for issuance under Chiron's previous plan. Under SFAS 123, pro forma compensation cost is recognized for the fair value of the employees' purchase rights, which was estimated using the Black-Scholes model and the following assumptions: expected volatility of 40%, 35% and 28% for 1999, 1998 and 1997, respectively; risk-free interest rates of 5.1%, 5.1% and 5.6% for 1999, 1998 and 1997, respectively; and an average expected life of one year for F-33 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 12--STOCKHOLDERS' EQUITY (CONTINUED) 1999, 1998 and 1997. No dividends were factored into the calculation in 1999, 1998 or 1997. The weighted-average fair value of the purchase rights granted was $8.78, $5.71 and $5.28 per share in 1999, 1998 and 1997, respectively. COMMON STOCK WARRANTS As a result of the acquisition of Cetus, warrants to purchase 600,000 shares of Chiron common stock were outstanding at December 31, 1999. The exercise price of the warrants is $13.13, and the warrants expire in July 2001. The warrants are currently exercisable. NOTES RECEIVABLE FOR STOCK PURCHASES The notes receivable for stock purchases were due from certain key employees and resulted from the exercise of stock options. The notes were full-recourse promissory notes, bearing interest at a rate of approximately 6.0% and were collateralized primarily by the stock issued upon the exercise of the stock options. As of December 31, 1999, there were no amounts outstanding relating to notes receivable for stock purchases. STOCK REPURCHASE PROGRAM In 1999, the Company's Board of Directors authorized the repurchase of up to 6.5 million shares of Chiron common stock from time to time on the open market to offset the dilution associated with the operation of the Company's stock option and employee stock purchase plans and the granting of share rights. Effective February 25, 2000, the Company's Board of Directors approved an additional 5.0 million share increase, thereby bringing the total number of shares authorized for repurchase to 11.5 million shares. The Board has authorized such repurchases through February 28, 2001. NOTE 13--OTHER EMPLOYEE BENEFIT PLANS RETIREMENT SAVINGS PLAN The Company sponsors a defined-contribution savings plan under Section 401(k) of the Internal Revenue Code covering substantially all full-time U.S. employees. Participating employees may contribute up to 15% of their eligible compensation up to the annual Internal Revenue Service contribution limit. The Company matches employee contributions according to a specified formula and contributed $3.8 million, $4.2 million and $3.7 million in 1999, 1998 and 1997, respectively. PENSION PLAN The Company has a non-contributory retirement program (the "program") covering substantially all employees of its wholly-owned German subsidiary. The benefits for this program are based primarily on years of service and employee compensation. The program is a defined-benefit pension plan and is not externally funded. F-34 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 13--OTHER EMPLOYEE BENEFIT PLANS (CONTINUED) The components of net periodic pension costs were as follows: 1999 1998 -------- -------- Service cost.............................................. $ 421 $ 436 Interest cost............................................. 405 431 Recognized actuarial loss................................. 38 24 ------- ------- $ 864 $ 891 ======= ======= The change in the projected benefit obligation, reconciliation of funded status and weighted average assumptions were as follows: 1999 1998 -------- -------- Change in projected benefit obligation: Projected benefit obligation at beginning of year....... $ 8,337 $ -- Acquisitions............................................ -- 5,722 Service cost............................................ 421 436 Interest cost........................................... 405 431 Benefits paid...........................................

Benefits payable under the plan are accrued when it is probable that employees will be entitled to benefits and the amount can be reasonably estimated in accordance with SFAS No. 112, "Employers' Accounting for Postemployment Benefits" (see Note 6). NOTE 14--NON-OPERATING INCOME AND EXPENSE In December 1999, the Company sold its Amsterdam manufacturing facility and related machinery and equipment assets to Synco B.V., a company owned by a director of the Company, for $15.0 million in cash. The Amsterdam manufacturing facility was part of the Company's biopharmaceuticals segment. The sale of the Amsterdam manufacturing facility resulted in a gain of $1.2 million, of which $0.9 million was included in "Gain on sale of assets" in the Consolidated Statement of Operations and $0.3 million was deferred as a result of the leaseback (see Note 8). At the time of the sale, the carrying amount of the Amsterdam manufacturing facility was $13.8 million. In 1999, 1998 and 1997, Chiron recognized operating expenses related to the Amsterdam manufacturing facility of $2.0 million, $1.7 million and $0.4 million, respectively. In December 1999, the Company sold certain assets that it had developed or acquired in connection with its research and development of a Cytomegalovirus ("CMV") vaccine to Aventis Pasteur (formerly Pasteur Merieux Connaught) for $10.0 million and licensed certain technology to Aventis Pasteur for use in connection with the CMV vaccine. The sale of these assets resulted in a gain of $7.5 million, which was included in "Gain on sale of intangible assets" in the Consolidated Statements of Operations. In August 1998, the Company sold its St. Louis, Missouri facility and related machinery and equipment assets to Genetics Institute, Inc. for $19.8 million in cash. The St. Louis facility was part of the Company's biopharmaceuticals segment. The sale of the St. Louis facility resulted in a net gain of $1.5 million, which was included in "Gain on sale of assets" in the Consolidated Statements of Operations. At the time of the sale, the carrying amount of the St. Louis facility was $18.3 million. In 1998 and 1997, Chiron recognized operating expenses related to the St. Louis facility of $3.2 million and $11.4 million, respectively. In December 1998, the Company completed the sale of its 30% interest in General Injectables & Vaccines, Inc. ("GIV") to Henry Schein, Inc. and received payment in full of certain advances made by the Company to GIV, for a total of $31.7 million in cash. The sale resulted in a net gain of $1.8 million, which was included in "Other income, net" in the Consolidated Statements of Operations. In September 1997, management determined that it could not find a suitable use for the Puerto Rico facility consistent with its previous expectations for the facility's use as a contract manufacturing plant. As a result, the Company reviewed the carrying amount of the Puerto Rico facility and related machinery and equipment assets for recoverability and, in accordance with SFAS 121, recorded a $31.3 million impairment loss to record the facility and related machinery at their individual estimated fair market values, determined on the basis of independent appraisals. In June 1998, the Company sold the facility and related F-36 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 14--NON-OPERATING INCOME AND EXPENSE (CONTINUED) machinery and equipment assets to IPR Pharmaceuticals, Inc. for $18.5 million in cash. The Puerto Rico facility was part of the Company's biopharmaceuticals segment. The sale of the Puerto Rico facility resulted in a net gain of $6.2 million, which was included in "Gain on sale of assets" in the Consolidated Statements of Operations. At the time of the sale, the carrying amount of the Puerto Rico facility was $11.1 million. In 1998 and 1997, Chiron recognized operating expenses related to the Puerto Rico facility of $2.1 million and $7.9 million, respectively.

Under this organizational structure, the Company has the following three reportable segments: (i) biopharmaceuticals, (ii) vaccines and (iii) blood testing. The biopharmaceuticals segment consists of products and services related to therapeutics, with an emphasis on cancer, infectious diseases and cardiovascular diseases as well as the development and acquisition of technologies related to recombinant proteins, small molecules and genomics. The vaccines segment consists principally of products and services related to adult and pediatric vaccines sold primarily in Germany and Italy and also sold in other international markets. The blood testing segment consists of Chiron's one-half interest in the pretax operating earnings of its joint business with Ortho-Clinical Diagnostics, Inc. ("Ortho"), a Johnson & Johnson company and an alliance with Gen- F-37 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 15--SEGMENT INFORMATION (CONTINUED) Probe Incorporated ("Gen-Probe"). Chiron's joint business with Ortho sells a line of immunodiagnostic tests, other than nucleic acid tests, required to screen blood for hepatitis viruses and retroviruses, and provides supplemental tests and microplate-based instrument systems to automate test performance and data collection. Chiron's alliance with Gen-Probe is focused on developing and selling products using nucleic acid testing ("NAT") to screen blood and plasma for infection by viruses. Certain revenues and expenses, particularly Novartis research and development funding, certain royalty revenues and unallocated corporate expenses, are not viewed by management as belonging to any one reportable segment. As a result, these items have been aggregated into an "Other" segment, as permitted by Statement of Financial Accounting Standards No. 131 "Disclosures about Segments of an Enterprise and Related Information" ("SFAS 131"). The accounting policies of the Company's reportable segments are the same as those described in Note 1--The Company and Summary of Significant Accounting Policies.

The benefit related to tax deductions for the Company's stock option plans was recorded as an increase to additional paid-in capital when realized. In 1999, 1998 and 1997, the Company realized tax benefits of approximately $42.8 million, $60.1 million and $17.9 million, respectively. F-42 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 16--INCOME TAXES (CONTINUED) RATE RECONCILIATION The reconciliation of the provision for income taxes, computed at the statutory U.S. income tax rate, to the reported amounts was as follows for continuing operations for the years ended December 31: 1999 1998 1997 -------- -------- -------- Federal tax provision at statutory rates...... 35.0% 35.0% 35.0% State taxes, net of federal benefit........... 2.0% 2.3% 7.1% Net impact of foreign tax rates and credits... 0.9% (4.3%) 5.4% Disposition and write-down of Puerto Rico facility.................................... -- (6.3%) 27.2% Impact of Novartis transaction costs not deducted in prior years.....................

As they more likely than not will be realized, net deferred tax assets have been recognized for U.S. federal and state purposes based on management's estimates of future taxable income and for certain foreign jurisdictions in which the Company's operations have historically been profitable. Such estimates are subject to change based upon future events, and accordingly, the amount of deferred tax assets recognized may increase or decrease from period to period. F-43 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 16--INCOME TAXES (CONTINUED) Significant components of the Company's deferred income tax liabilities and assets from continuing operations were as follows at December 31: 1999 1998 -------- --------- (IN THOUSANDS) Deferred income tax liabilities: Basis differences--purchase accounting............... $ 4,793 $ 9,631 Patent costs expensed for tax purposes............... 10,719 12,358 Depreciation and purchased technologies.............. 5,292 9,539 Other................................................ 7,007 1,527 -------- --------- 27,811 33,055 -------- --------- Deferred income tax assets: Basis differences--purchase accounting and intangibles........................................ 67,045 72,672 Capitalized research and development costs........... 3,395 -- Prepaid income....................................... 18,761 37,800 Reserves and expense accruals........................ 44,194 63,866 Net operating loss carryforwards..................... 21,504 46,762 Business credit carryforwards........................ 9,456 9,034 Other................................................ 2,341 2,360 -------- --------- 166,696 232,494 Less valuation allowance.............................

The valuation allowance of $86.1 million as of December 31, 1999 related to net operating loss carryforwards and intangible assets in certain foreign jurisdictions. Subsequently recognized tax benefits relating to the valuation allowance for deferred tax assets at December 31, 1999 will be allocated as follows (in thousands): Income tax benefit.......................................... $82,852 Goodwill and other noncurrent intangible assets............. 3,204 ------- $86,056 ======= TAX OPERATING LOSS AND CREDIT CARRYFORWARDS At December 31, 1999, the Company had foreign net operating loss carryforwards of approximately $61.0 million, principally available to offset future taxable income indefinitely, and federal and state business credits of $9.5 million, expiring in 2013. F-44 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 17--LEGAL PROCEEDINGS The Company is party to various claims, investigations and legal proceedings arising out of the normal course of its business. These claims, investigations and legal proceedings relate to intellectual property rights, contractual rights and obligations, employment matters, shareholder derivative claims, claims of product liability and other issues. While there can be no assurance that an adverse determination of any such matters could not have a material adverse impact in any future period, management does not believe, based upon information known to it, that the final resolution of any of these matters will have a material adverse effect upon the Company's consolidated financial position and annual results of operations and cash flows.

In addition, the mix of products sold and the introduction of new products will affect the comparability of gross margins from quarter to quarter. As a consequence, Chiron's results in any one quarter are not necessarily indicative of results to be expected for a full year. Accordingly, the Company should be evaluated on the basis of annual financial information. Net income in the fourth, third and second quarters of 1999 included income tax benefits of $4.4 million, $15.3 million and $0.7 million, respectively, in the "Gain on disposal of discontinued operations." Net income in the third quarter of 1999 also included a gain of $4.8 million upon sale of a portion of real estate assets of the Company's discontinued operations. This gain was recorded in the "Gain on disposal of discontinued operations." Net income in the third quarter of 1998 included income tax benefits of $45.5 million in the "Gain on disposal of discontinued operations." The results of continuing operations for the fourth quarter of 1999 included a $1.9 million reduction in restructuring and reorganization charges due to revised estimates of termination and other employee-related costs, a $5.0 million reduction in other operating expenses resulting from a change in estimated tax accruals related to certain employee payments recorded in 1995 in connection with the Novartis transaction, a $0.9 million gain on the sale of assets (see Note 14), a $7.5 million gain on the sale of intangible assets (see Note 14) and a $3.3 million unrealized holding gain related to equity securities classified as trading. In the fourth quarter of 1999, the Company also recorded a $5.9 million reclassification from cost of sales to other operating expenses to record contract manufacturing expenses in accordance with the Company's accounting policy. The results of continuing operations for the third quarter of 1999 included a $1.9 million reduction in restructuring and reorganization charges due to revised estimates of property-related and accruals recorded in connection with the idling of the St. Louis facility, as well as revised estimates of termination and other employee-related costs, and a $2.0 million reduction in other operating expenses resulting from a change in estimated tax accruals related to certain employee payments recorded in 1995 in connection with the Novartis transaction. The results of continuing operations for the second quarter of 1999 included a $6.4 million reduction in other operating expenses resulting from a change in estimated tax accruals related to certain employee payments recorded in 1995 in connection with the Novartis transaction. In the fourth quarter of 1998, the Company recorded a $7.6 million reclassification from cost of sales to other operating expenses to record contract manufacturing expenses in accordance with the Company's accounting policy. The results of continuing operations for the third quarter of 1998 included a $3.3 million reduction in cost of sales resulting from a change in estimated accruals created in prior periods and a $1.5 million gain on the sale of assets (see Note 14). The results of continuing operations for the second quarter of 1998 included a $6.0 million reduction in cost of sales due to a change in estimated property tax accruals created in prior periods, a $3.7 million reduction in restructuring and reorganization charges due to a revised estimate of property and other tax-related accruals recorded in 1995 in connection with the idling of the Puerto Rico facility and a $6.2 million gain on the sale of assets (see Note 14). F-46 CHIRON CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 NOTE 19--SUBSEQUENT EVENTS Through February 17, 2000, holders of 325 of the 5.25% convertible subordinated debentures converted those debentures into 52,704 shares of the Company's common stock, at a conversion price of $30.83 per share. The face value of the converted debentures was $1.6 million, with amortized costs of $1.5 million. On February 7, 2000, the Company sold various assets of its Australian subsidiary ("the Australian assets") to Mimotopes Pty. Ltd. ("Mimotopes"), a wholly-owned subsidiary of MitoKor, for $1.0 million in cash, $2.0 million ($1.6 million discounted) in non-interest bearing promissory notes, which are due on August 7, 2001 and February 7, 2003, and 500,000 shares of MitoKor Series E convertible preferred stock, to which the Company assigned no fair value due to the early-stage nature of MitoKor. Mimotopes also assumed various liabilities of the Company's Australian subsidiary. In connection with the sale, the Company wrote off $1.3 million in leasehold improvements, which became the property of the landlord upon termination of the Australian subsidiary's building lease, and incurred selling costs of $0.4 million. The Australian assets were part of the Company's biopharmaceuticals segment. The sale of the Australian assets, net of liabilities assumed, resulted in a net loss of $0.2 million. As of December 31, 1999, the carrying amount of the Australian assets, net of liabilities to be assumed, was $1.1 million and was recorded in the Consolidated Balance Sheets as "Other current assets."
