BUSINESS GENERAL NeXstar Pharmaceuticals, Inc., a Delaware corporation ("NeXstar Pharmaceuticals" or the "Company"), is an integrated biopharmaceutical company engaged in the discovery, development, manufacture and marketing of proprietary pharmaceutical products to treat life-threatening and other serious oncological, hematological and infectious diseases. NeXstar Pharmaceuticals employs a broad range of proprietary technologies in the discovery and formulation of pharmaceutical products, including the Company's liposome drug delivery technology; a powerful combinatorial chemistry technology known as the SELEX process that rapidly identifies novel oligonucleotide compounds with potential therapeutic and diagnostic benefits; and Evolutionary Chemistry, designed to rapidly discover small organic molecules to serve as orally available drugs. The Company's technologies have produced two approved drugs and several drug candidates that are in clinical or preclinical development and have provided the basis for a significant pipeline of drug development candidates. On February 28, 1999, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which the Company will be acquired through merger (the "Merger") by Gilead Sciences, Inc., a Delaware corporation ("Gilead"). Pursuant to the terms of the Merger Agreement, each issued and outstanding share of Company common stock, par value $0.01 per share ("Company Common Stock"), will be converted into the right to receive that number of shares of Gilead common stock, par value $0.001 per share ("Gilead Shares") equal to the "Exchange Ratio". The "Exchange Ratio" equals 0.425, provided, however, that if the Gilead Share Value (defined as the average of the closing prices of the Gilead Shares as reported on the Nasdaq National Market for the 20 consecutive trading days ending on the third trading day preceding the date on which the stockholders of the Company vote on the Merger at the special meeting of the Company's stockholders called to approve and adopt the Merger Agreement and the Merger) is (i) less than $36.47, then the Exchange Ratio shall be equal to the lesser of 0.50 or a fraction having a numerator equal to $15.50 and having a denominator equal to the Gilead Share Value, or (ii) greater than $45.88, then the Exchange Ratio shall be equal to the greater of 0.3786 or a fraction having a numerator equal to $19.50 and having a denominator equal to the Gilead Share Value. Cash will be paid in lieu of fractional shares. The Merger is subject to several conditions, including that it be approved by the stockholders of both the Company and Gilead. See "--Agreement and Plan of Merger with Gilead Sciences, Inc." Currently, the Company markets AmBisome, an antifungal agent, and DaunoXome, an anticancer drug, which had combined 1998 revenues of $107.9 million. The United States Food and Drug Administration ("FDA") has approved AmBisome for use in the United States as a primary therapy for patients with a low white blood cell count (febrile neutropenia) who have a presumed fungal infection, also known as fever of unknown origin or FUO, or with visceral leishmaniasis and as a secondary treatment for fungal infections that do not respond to amphotericin B treatment. AmBisome has been approved for sale by the regulatory authorities in 38 countries for the treatment of life-threatening fungal infections, including 16 countries in which it has been approved as a primary therapy for some form of fungal infection. DaunoXome has been approved for sale as a primary therapy for HIV-associated Kaposi's sarcoma in 24 countries, including the United States, Canada and all significant Western European markets. The Company continues to conduct clinical trials with AmBisome in a variety of settings with the goal of expanding its uses. The Company is conducting clinical trials with DaunoXome in an attempt to find additional indications and is planning clinical trials of DaunoXome in patients with acute myeloblastic leukemia and chronic lymphocytic leukemia. In addition, the Company is conducting Phase II clinical trials 1 with a third product, the antibiotic MiKasome, a liposomal formulation of amikacin (a potent aminoglycoside antibiotic) for complicated urinary tract infections, cystic fibrosis, nosocomial pneumonia and tuberculosis. The Company recently commenced Phase I clinical trials for its NX211 product, a liposomal form of Glaxo Wellcome, Inc.'s lurtotecan product, a camptothecin derivative and potent anti-cancer compound. Each of AmBisome, DaunoXome, MiKasome and NX211 was developed using the Company's liposomal drug delivery technology. Liposomes are subcellular-sized spheres composed primarily of molecules called phospholipids. By encapsulating in liposomes certain drugs that in their free state are dosed at or close to toxic levels, it is possible to increase the therapeutic index of the active drug (I.E., to increase the efficacy of the active drug relative to the severity of its side effects). The Company utilizes two other powerful proprietary technologies for drug discovery and delivery-- the SELEX process and Evolutionary Chemistry (formerly called the Parallel SELEX process). The SELEX process, a combinatorial chemistry technology, can rapidly identify novel oligonucleotide compounds (also referred to as aptamers) with a high affinity for specified disease targets and therefore potential use as drug candidates or as diagnostic agents. The Company has discovered several aptamers using the SELEX process which are currently in the research and early clinical/preclinical development stages. In 1998, the Company received FDA approval of its Investigational New Drug ("IND") application, and has begun clinical trials for NX1838, its aptamer which binds to vascular endothelial growth factor ("VEGF"). VEGF is a growth factor which is believed to contribute to age-related macular degeneration, the leading cause of adult-onset blindness, by inducing the formation of blood vessels associated with the disease state. Evolutionary Chemistry is a proprietary technology being developed by the Company to rapidly identify small organic molecules intended to serve as orally available drugs. The potential advantages of Evolutionary Chemistry are that, unlike current combinatorial chemistry drug discovery methodologies, it does not require tagging chemistries, high reaction yields or laborious screening steps. The Company has a substantial marketing, manufacturing and medical/regulatory infrastructure in the United States, Europe and Australia and markets its products through third-party distributors in other areas throughout the world. The Company markets its products through its own sales representatives throughout Europe, in the United States (where the Company co-markets AmBisome with Fujisawa Healthcare, Inc.) and in Australia as well as through third-party distributors. The Company has established marketing subsidiaries in most of its significant European markets. The Company has built and continues to enhance its medical/regulatory staff in the U.S. and Europe as necessary to facilitate the approval of drug candidates, which have been, or may be, generated by the Company's drug discovery efforts. The Company manufactures its liposomal drugs. In late 1997, the Company established its NeXstar Technology Products division which included the Company's proprietary technology called Product Anchored Sequential Synthesis ("PASS"), a method of synthesizing the oligonucleotides that are the basis for the products being developed using the SELEX process. In July 1998, the Company established Proligo L.L.C., a Delaware limited liability company ("Proligo"), as a wholly-owned subsidiary and transferred all of the assets of the NeXstar Technology Products division to Proligo. On August 15, 1998, the Company sold a 51% interest in Proligo to SKW Americas, Inc. ("SKW") in exchange for $15 million cash and a 49% interest in PerSeptive Biosystems GmbH, a German corporation ("PerSeptive"). As part of the transaction, the Company contributed its interest in PerSeptive to Proligo, and SKW contributed its 51% interest in PerSeptive to Proligo. Proligo has agreed to manufacture oligonucleotides required by the Company at cost plus a fixed percentage. NeXstar Pharmaceuticals was formed in 1991 as NeXagen, Inc. On February 21, 1995, the Company was merged with Vestar, Inc., a Delaware corporation founded in 1981, and changed its name to NeXstar Pharmaceuticals, Inc. 2 SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS Certain statements in this Report constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995.

PRODUCTS AND MARKETS AMBISOME AmBisome is a liposomal formulation of amphotericin B, a well-established antifungal agent that is effective against a broad spectrum of fungi. NeXstar Pharmaceuticals has received marketing approval for AmBisome as a treatment for life-threatening fungal infections in 38 countries, 16 of which have granted approval as a first line therapy for some form of fungal infection and the remainder of which have granted approval for use when conventional amphotericin B treatment fails. AmBisome has also been approved as a treatment for visceral leishmaniasis in several countries and is approved in four countries for prophylactic treatment to prevent fungal infection after liver transplantation. In addition, AmBisome has been approved for the treatment of fever of unknown origin (FUO) in the U.S. and six other countries. Pursuant to a collaborative agreement, the Company and Fujisawa Healthcare, Inc., as successor to Fujisawa USA, Inc. ("Fujisawa"), co-develop and co-promote AmBisome in the United States. Fujisawa has sole marketing rights to AmBisome in Canada. The Company has sole marketing rights to AmBisome in the rest of the world, provided that the Company is required to pay royalties to Fujisawa in connection with sales in most significant Asian markets, including Japan. In connection with U.S. sales, the Company sells AmBisome to Fujisawa at cost; Fujisawa collects all payments from the sale of AmBisome in the U.S. and pays the Company 20% of the gross profits from all sales. The Company has also licensed the rights to develop and market AmBisome in Japan to Sumitomo Pharmaceuticals Co., Ltd. ("Sumitomo"). Under the terms of its license with the Company, Sumitomo is required to make payments to the Company if certain clinical and commercial milestones are met and to pay the Company royalties on all Japanese sales of AmBisome. Sumitomo has paid a total of $10 million to NeXstar in connection with the achievement of milestones, including $3 million in 1998 related to the filing of a new drug application in Japan. Under the terms of the license, Sumitomo is required to make an additional milestone payment to the Company if AmBisome is approved for sale in Japan. PRODUCT PROFILE. Amphotericin B, an antifungal agent used to treat a broad spectrum of fungal infections, has been a commonly used drug for the treatment of systemic fungal infections. The clinical usefulness of amphotericin B is limited, however, because serious toxicity can occur prior to achieving effective therapy. NeXstar Pharmaceuticals has used its proprietary technology to develop AmBisome, a liposomal product that incorporates amphotericin B. The maximum tolerated dose of AmBisome in some animal models is up to 75 times that of the free drug, permitting higher daily and cumulative doses of amphotericin B to be delivered to the diseased tissues, while simultaneously greatly reducing the normal acute and chronic toxicity often associated with conventional amphotericin B therapy. NeXstar Pharmaceuticals believes that the increased safety profile of AmBisome is due to a proprietary manufacturing process that tightly binds amphotericin B into the membrane of the liposome, preventing the free drug from escaping into the blood stream. AmBisome is sold as a lyophilized (freeze-dried) product that is easily reconstituted by adding sterilized water. In the United States and many other countries, AmBisome has an approved shelf life of 36 months. However, in most European countries, AmBisome has an approved shelf life of 30 months. MARKET. The Company's marketing efforts for AmBisome are primarily directed at physicians who treat patients with systemic fungal infections and presumptive fungal infections. Systemic fungal infections are serious infections with a mortality rate of up to 70% and are commonly caused by species of CANDIDA, ASPERGILLUS or CRYPTOCOCCUS, as well as a variety of less common organisms. These infections can occur in patients whose immune systems have been compromised by other diseases or by the treatment of other medical conditions. The largest population of immune-impaired patients consists of organ/bone marrow transplant patients, heavily treated cancer patients (principally those with leukemias or lymphomas) and 5 AIDS patients. AmBisome is also currently used in a number of countries for the treatment of visceral leishmaniasis, a parasitic infection. DAUNOXOME DaunoXome is a liposomal formulation of daunorubicin, a well-characterized and long-used chemotherapeutic agent. DaunoXome has been approved in the United States, Canada and 22 other countries as a primary therapy for HIV-associated Kaposi's sarcoma ("KS"). PRODUCT PROFILE. DaunoXome uses a proprietary tumor targeting technology for delivering daunorubicin into tumor cells. This targeted liposomal delivery system consists of small liposomes that encapsulate the daunorubicin in their internal aqueous space. The size of the liposomes used in DaunoXome was selected, in part, so that the liposomes can escape from circulation through the more porous blood vessels that are generally found in tumors. In some animal models, DaunoXome's formulation permits a concentration of the therapeutic agent in tumors of 5 to 10 times the concentration achieved with intravenous administration of the free drug. The same animal tests have also demonstrated up to 10 times the efficacy as the equivalent level of daunorubicin in its free drug form. Further, these animal models have demonstrated a substantial reduction in certain toxicities associated with daunorubicin. DaunoXome has an approved shelf life of 52 weeks in the United States and 40 weeks in Canada and most European countries. MARKET. The Company's initial targeted market for DaunoXome has been AIDS patients who suffer from KS, a malignant disease characterized by widely disseminated lesions in the skin, mucous membranes, lymph nodes and viscera. With the advent of combination therapies for AIDS, the incidence of KS has declined in recent years which has substantially limited the market for the indication for which DaunoXome has been approved. CLINICAL TRIALS, PRECLINICAL TRIALS AND REGULATORY STATUS The Company is continuing clinical trials for both AmBisome and DaunoXome for currently approved and additional indications and two other liposomal products, MiKasome and NX211, which are in clinical trials. The Company received FDA approval for its Investigational New Drug application in the United States ("IND") in 1998 for its aptamer antagonist to VEGF for the treatment of age-related macular degeneration. This was the first IND application filed by the Company for one of its aptamers. The Company has begun clinical trials for NX211 in Europe and plans to file an IND in the United States for NX211 in the first half of 1999. No assurance can be given that proposed clinical trials will be initiated or that any clinical trials or preclinical development work will result in any commercially successful new drugs or approval of any additional indications for AmBisome or DaunoXome. AMBISOME NeXstar Pharmaceuticals continues to conduct clinical trials with AmBisome in a variety of settings with the aim of expanding the uses of this antifungal drug. The Company has recently concentrated its clinical development for AmBisome on empiric therapy for presumed fungal infections among patients at high risk for such infections, first line therapy for systemic and/or deep fungal infections and prophylaxis against systemic fungal infections following chemotherapy or bone marrow transplantation. In a double-blind trial, 687 adult and pediatric patients with neutropenia (a low number of infection-fighting white blood cells) and persistent fever that did not resolve with antibiotic treatment were randomized to receive either conventional amphotericin B or AmBisome. Results of the study, which was sponsored by Fujisawa, show that, overall, AmBisome was associated with a therapeutic success rate (measured by a combination of factors including, among others, resolution of fever, absence of emergent fungal infection and patient survival for at least seven days after therapy) equivalent to conventional amphotericin B, but was significantly more effective in the prevention of proven breakthrough fungal 6 infections. In addition, among patients treated with AmBisome compared with patients treated with conventional amphotericin B, there was a significant reduction in the incidence of infusion-related fever, chills/rigors, cardiorespiratory events and the development of nephrotoxicity. Patients treated with amphotericin B had a slightly lower incidence of diarrhea and nausea than those treated with AmBisome. The study also indicated that there was a statistically significant reduction in kidney toxicity with AmBisome compared to conventional amphotericin B. Overall, there was a lower incidence of adverse events associated with the use of AmBisome as compared to amphotericin B. The Company has completed two additional randomized open label clinical trials comparing the safety and efficacy of AmBisome to conventional amphotericin B in the empiric treatment of patients with fever of unknown origin (FUO) and severe neutropenia who had presumed or confirmed fungal infection. These patients were receiving intensive chemotherapy or had underlying hematological disease. One clinical trial enrolled adults (193 patients) and the other pediatric subjects (205 patients). These two clinical trials indicated that AmBisome had an improved safety profile compared with amphotericin B and there was a trend towards improved efficacy for AmBisome, specifically for the higher dose group (3 mg/ kg). A double-blind, placebo-controlled, randomized clinical trial in 86 patients studying the efficacy and safety of AmBisome as prophylaxis following liver transplantation showed a trend towards improved efficacy for AmBisome compared to amphotericin B. Additionally, the Company has completed five clinical trials in which patients with confirmed systemic and/or deep fungal infections were treated with AmBisome. In these trials, AmBisome was clinically at least as effective as amphotericin B and the overall fungal eradication rate was greater for AmBisome than for amphotericin B. NeXstar Pharmaceuticals, in conjunction with Fujisawa, is conducting three Phase III clinical trials of AmBisome in the United States for the treatment of histoplasmosis and for the treatment of CRYPTOCOCCUS. The trials for histoplasmosis are being monitored and analyzed by the Mycology Study Group of the National Institutes of Health. In addition, a randomized, double-blind comparative trial of AmBisome versus Abelcet (a lipid-based amphotericin B product marketed by The Liposome Company, Inc.) in the empirical treatment of febrile neutropenia has been completed, and the data will be presented in late- March 1999. DAUNOXOME The Company is seeking to expand the number of approved indications for DaunoXome. The Company has completed clinical trials and is continuing to perform additional studies aimed at optimizing the treatment of KS. The completed clinical trials in KS have evaluated the safety and efficacy of higher dose regimens and the treatment of the pulmonary manifestations of KS. In addition, the Company is pursuing a strategy of evaluating the therapeutic potential of DaunoXome in hematological malignancies (leukemias and lymphomas), indications in which the efficacy and safety of daunorubicin is well established. The Company, in a Phase II clinical trial, has substituted DaunoXome for doxorubicin in a CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) regimen (COP-X) in the treatment of high grade lymphomas. The Company has completed a Phase I study in acute myeloblastic leukemia in combination with cytosine-arabinoside (Ara-C) and is planning Phase II development for this indication as well as for chronic lymphocytic leukemia. MIKASOME MiKasome is a liposomal formulation of amikacin, which is a member of a class of antibiotic compounds called aminoglycosides. Traditionally, serious bacterial infections are treated with an injectable antibiotic such as amikacin. In its free (unencapsulated) form, amikacin is a potent antibiotic, but can be associated with side effects such as kidney failure, hearing loss or loss of balance. The target product 7 profile for MiKasome, as compared to free amikacin, includes significantly improved safety, extended circulation times, increased penetration to sites of infection and a broader range of antimicrobial activity. The Company began an initial 75-patient Phase II study of MiKasome in November 1997 to assess its use in patients with complicated urinary tract infections ("UTIs"). This study is now completed, and the results will be publicly presented in the first half of 1999. Complicated UTIs are functional or anatomic abnormalities of the urinary tract often resulting in recurrent infections in patients despite antibiotic therapy. The Company is now initiating a follow-up study comparing three doses of MiKasome in this indication. Additional Phase II studies are ongoing in adults with cystic fibrosis and in patients with nosocomial (hospital acquired) pneumonia and tuberculosis. The Company is planning additional studies in patients with febrile neutropenia and in patients with impaired renal function. Phase I studies using MiKasome have indicated that (i) at the doses studied, MiKasome did not cause toxicity or impairment to the kidneys, to hearing or to balance; (ii) the half-life (an indication of the time the product stays in the body) is up to seven days, compared to approximately two hours for free amikacin; and (iii) relatively constant antibiotic levels appear to be maintained with once weekly dosing of MiKasome. Preclinical studies with MiKasome in animals have indicated that (i) MiKasome has a much longer half-life than free amikacin; (ii) MiKasome administered daily was as effective as free amikacin administered twice a day in the treatment of endocarditis caused by PSEUDOMONAS, a Gram-negative bacteria; and (iii) MiKasome was more effective than free amikacin in decreasing the incidence and severity of myocarditis (inflammation of the muscular walls of the heart). In preclinical studies, the pathogens against which MiKasome has shown at least equivalent, if not improved efficacy compared to free amikacin, are PSEUDOMONAS AERUGINOSA, STAPHYLOCOCCUS AUREUS, KLEBSIELLA PNEUMONIAE, MYCOBACTERIUM AVIUM complex and MYCOBACTERIUM TUBERCULOSIS. The current development plan for MiKasome includes clinical trials for indications in patients with moderate, severe and life-threatening Gram-negative bacterial infections, including, but not limited to, those infections which are the focus of the planned, or currently conducted, Phase II clinical trials. NX211 NX211 is the Company's liposomal formulation of a topoisomerase I inhibitor called lurtotecan, a camptothecin derivative and potent anti-cancer compound licensed from Glaxo Wellcome, Inc. and Glaxo Group Limited (together, "Glaxo"). Pursuant to the License Agreement, dated May 27, 1998 (the "Glaxo License Agreement"), between the Company and Glaxo, the Company has an exclusive worldwide license to lurtotecan, provided that Glaxo has the option within certain parameters to participate in the further development of NX211. Topoisomerase I is required for DNA replication, an activity which is integral to the normal division of cells. Lurtotecan, as is the case with other camptothecin analogues, binds tightly to topoisomerase I, causing cell cycle arrest. Data from both preclinical and clinical studies indicate that the cytotoxicity of camptothecins (both topotecan, a commercially available camptothecin, and lurtotecan) is directly related to the length of their exposure. The Company's preclinical experiments with liposomal lurtotecan show a threefold increase in the therapeutic index compared to the free drug. The Company believes that its liposomal formulation of lurtotecan will increase the drug's plasma circulation time and exposure, and thus increase its therapeutic index. The Company has planned three Phase I clinical trials of NX211. The first, being conducted in the Netherlands, is already underway, and is designed to determine the single maximum tolerated dose of NX211. The second and third Phase I trials will be conducted in Canada and the United States, respectively. Documentation for the Canadian trial has been submitted, and the trial, which will evaluate the safety and pharmacokinetics of doses on days 1, 2, and 3, is scheduled to begin in March 1999. The U.S. 8 trial is expected to begin prior to the end of the second quarter in 1999, after submission of an IND application to the FDA at the beginning of the second quarter of 1999. Results from these three Phase I trials will be used to determine the best dose and dose schedule for Phase II trials of NX211. Phase II clinical trials are expected to evaluate NX211 in ovarian cancer and small-cell lung cancer. NX1838 NX1838 is the first aptamer identified by the Company's proprietary SELEX technology to enter clinical development, and the first aptamer ever to be studied under a U.S. IND. NX1838 is a potent and selective inhibitor of human vascular endothelial growth factor ("VEGF"), a key cytokine responsible for the growth of new blood vessels in the body (a process known as angiogenesis). NX1838 binds with high affinity to VEGF and prevents its attachment to complementary cell receptors. As a result, the sequence of events leading to angiogenesis is interrupted. The Company has begun clinical trials with NX1838 in a disease known as Age-Related Macular Degeneration ("AMD"). AMD is characterized by progressive degenerative changes in the central portion of the retina that can lead to loss of visual acuity over time. AMD is classified into one of two general subgroups, the atrophic or "dry" form of the disease and the exudative or "wet" form. The "wet" form of the disease, accounting for approximately 20% of AMD cases, is a more severe condition in which there is a sudden, often substantial, loss of central vision. AMD is characteristically a disease of the elderly population (i.e., persons age 65 or older) and is the single leading cause of blindness in developed countries around the world. It is estimated that in the United States 6% of individuals ages 65-74, and 20% of those older than 75, have AMD. The abnormal growth of blood vessels behind the retina is a feature of AMD as the disease progresses to the more advanced stages. It is believed that VEGF plays a key role in initiating the abnormal angiogenesis seen in AMD. Studies in animals have demonstrated that NX1838 can inhibit angiogenesis in a variety of settings. Systemic administration of NX1838 to rats resulted in significant inhibition of VEGF-dependent angiogenesis in the corneal tissue of the eye. Other tests in animals confirm the effect of NX1838 on angiogenesis and confirm that the drug is sufficiently safe to begin human trials. Phase I clinical studies in humans (aimed principally at confirming the drug's safety profile) are underway, and the Company is preparing for the Phase II program, which will provide initial information on the effectiveness of NX1838 in halting the progression of AMD. RESEARCH AND DEVELOPMENT The Company's research and development activities focus on the identification of potential drug candidates using its three significant proprietary technologies: liposome technology, the SELEX process and Evolutionary Chemistry. The Company develops its most suitable candidates into drugs for oncological, hematological and infectious disease. In addition, the Company is developing SELEX process-derived oligonucleotide compounds as non-therapeutic products, including diagnostic agents. LIPOSOME TECHNOLOGY NeXstar Pharmaceuticals believes that it has substantial technological strengths in the development of liposome products. The Company's proprietary liposome drug delivery technology enables it to develop products with significant potential advantages over intravenous administration of a conventional drug, including concentrating the drug on the targeted disease, extending the time the drug remains in the blood stream to prolong the therapeutic effect and reducing toxic side effects. The Company's liposome technology may be used as a method of drug delivery in connection with drugs developed or being developed pursuant to the Company's other technologies. The use of liposomes has the potential for increasing the efficacy and safety of such drugs. 9 NeXstar Pharmaceuticals intends to continue to develop products based on its liposome platforms for oncological, hematological and infectious diseases. The Company has identified certain generic and proprietary oncological compounds that may benefit substantially from encapsulation in tumor-targeted liposomes and has begun formulation studies for these compounds. As part of its strategy to develop liposomal drugs, the Company has discussed, and will continue to discuss, collaborative relationships with other companies to encapsulate such companies' proprietary drugs in liposomes in order to increase the efficacy and safety of the free drugs. THE SELEX PROCESS: SYSTEMATIC EVOLUTION OF LIGANDS BY EXPONENTIAL ENRICHMENT NeXstar Pharmaceuticals' proprietary combinatorial chemistry technology, called the SELEX process, can rapidly identify compounds that bind tightly and selectively to molecular targets. Complementary shape (sometimes described as a "lock and key") is fundamental to drug discovery research. In searching for potential drug candidates, the scientist looks for the drug candidate (key) that best fits the disease causing molecular target (lock). In this search, it is advantageous to have a large library of potential drug candidates (keys) to test against the target molecule (to attempt to fit into the lock). In developing effective drug products, it is also advantageous to have a drug candidate that binds tightly to the target molecule and not to other molecules. A drug compound with high affinity binding properties is more likely to be effective at low doses and induce fewer side effects than a drug compound with low affinity for the disease target. High specificity also reduces the likelihood of potential side effects since the drug compound is unlikely to interact with targets not involved in the particular disease. The SELEX process generates a pool of up to one million billion (10(15)) oligonucleotide compounds (keys) and then rapidly searches this pool of compounds to identify the compounds that bind tightly and with a high degree of specificity to the chosen disease-causing molecular target. Typically, the SELEX process creates drug candidates in a matter of weeks or months. The lead oligonucleotide compound resulting from the application of the SELEX process to a particular disease target is referred to as an aptamer. The Company believes that its SELEX process reduces the time and cost of identifying lead compounds and ultimately will reduce the time and cost involved in discovering and developing effective pharmaceutical products. PHARMACOKINETICS AND STABILITY. The Company has improved the stability and the pharmacokinetic activity of aptamers developed using the SELEX process. Like all oligonucleotides, aptamers can be destroyed in the body by nucleases, enzymes that attack and break down RNA and DNA molecules. In order to improve the stability of aptamers, the Company has created an assortment of proprietary nucleotides (the building blocks for RNA and DNA) modified to resist nuclease attack. Compared to natural RNA, SELEX process-derived RNA aptamers that incorporate modified nucleotides are up to 200 times more stable in the blood of test animals. In addition, the circulation time of aptamers can be modified by altering the formulation of the aptamers (E.G., by the addition of polyethylene glycol). Using its modified aptamers, the Company has demonstrated specific pharmacologic activity in animal models representing different disease processes. AUTOMATION. Currently, much of the SELEX process is labor intensive. By automating the SELEX process, the Company believes that it will increase the speed at which it is able to identify aptamers. The Company has contracted with RELA, a Colorado MEDtech affiliate, which is a custom product development and manufacturing service company, to design, construct and test a proof of principle machine in collaboration with the Company. THERAPEUTIC APPLICATIONS OF SELEX PROCESS-DERIVED COMPOUNDS. SELEX process-derived aptamers have potential therapeutic uses because of their high affinity and specificity for their targets. The Company has identified aptamers to a variety of different targets. In addition to NX1838, an aptamer which binds to VEGF (see "Clinical Trials, Preclinical Trials and Regulatory Status-- NX1838"), the Company has identified aptamers for other targets, including the following: platelet-derived growth factor (implicated in tumor growth and the progression of other proliferative diseases such as restenosis and fibrosis), P-selectin 10 (implicated in the process of inflammation), basic fibroplast growth factor (implicated in restenosis, fibrosis and cancer), human neutrophil elastase (an enzyme capable of degrading a wide variety of connective tissue proteins) and human complement C5 (implicated in the process of inflammation). DIAGNOSTIC APPLICATIONS OF SELEX PROCESS-DERIVED COMPOUNDS. In addition to efforts aimed at the potential use of SELEX process-derived aptamers as therapeutic agents, the Company has devoted significant research and development efforts to demonstrating that aptamers derived from its SELEX process have utility in a variety of diagnostic applications. TAQ (THERMUS AQUATICUS) POLYMERASE APTAMERS. The development of the polymerase chain reaction ("PCR") has revolutionized many aspects of modern molecular biology. PCR allows the rapid and efficient amplification of specific sequence DNA molecules. The molecule responsible for PCR is the thermostable DNA polymerase enzyme TAQ polymerase. While the utility of PCR is high, it is also flawed because it can function at low temperatures, allowing the DNA primers to non-specifically bind to each other and to the target DNA molecule to be amplified. This results in undesirable amplification of DNA and makes interpretation of the PCR results difficult. In collaboration with Roche Molecular Systems, Inc., NeXstar Pharmaceuticals has identified SELEX process-derived DNA aptamers that bind to TAQ polymerase and inhibit its activity at low temperatures where the non-specific binding problem occurs. At low temperatures, the DNA aptamers bind to TAQ polymerase and prevent undesirable DNA amplification. At high temperatures (where TAQ polymerase functions in the manner desired), the DNA aptamers, by design, no longer bind and inhibit TAQ polymerase, allowing this enzyme to amplify only the desired DNA target. The Company's DNA aptamers appear to have substantial advantages compared to traditional PCR applications, especially in clinical diagnostics. OTHER DIAGNOSTIC APPLICATIONS. The Company has demonstrated that a SELEX process-derived aptamer which binds to VEGF can be used in place of an antibody in a common diagnostic assay known as a sandwich enzyme-linked immunosorbent assay ("ELISA"). This assay usually requires two antibodies that bind simultaneously to the molecule to be analyzed. The first antibody captures the target, and the second antibody is used for detection (the two antibodies are thought of as two pieces of bread that "sandwich" the target molecule). The use of two antibodies greatly reduces the probability of misdiagnosis. In the Company's demonstration, the detection antibody in the diagnostic assay was replaced with a SELEX process-derived aptamer specific for VEGF, indicating that SELEX process-derived aptamers might be effective and useful diagnostic reagents. In addition to using aptamers to replace one of the antibodies in ELISA, the Company believes that aptamers with the capability to form covalent bonds with their target molecules may allow the development of new diagnostic methodologies. In this context, the two components of interaction between the aptamer and its target (initial binding followed by the formation of a covalent bond) would provide two dimensions of specificity, analogous to the use of two different antibodies. The Company is developing its Photo-SELEX process to identify aptamers that have the capacity to cross-link with target molecules upon excitation by light of a specific wavelength. Aptamers may have several advantages over antibodies for use as clinical diagnostic reagents. Aptamers are approximately ten times smaller than antibodies and are completely chemically defined (allowing for consistent manufacturing and ease of modification). Aptamers can be "rationally" designed, I.E., the SELEX process can be designed so that the resulting aptamer is capable of binding to the target molecule in a particular assay solution or with a desired target specificity. Because the entire SELEX process is carried out IN VITRO, aptamers can be developed for most targets, including those for which it is difficult to obtain antibodies. The Company also believes that Proligo will be able to use its PASS technology for large-scale manufacture of these aptamers at a substantially lower cost than the current cost of most antibodies. See "--Proligo L.L.C. and PASS: Product Anchored Sequential Synthesis." 11 EVOLUTIONARY CHEMISTRY The Evolutionary Chemistry process (formerly called the Parallel SELEX process) is a proprietary technology being developed by the Company to discover small-molecule drug and agrochemical candidates. The Evolutionary Chemistry process has several potential advantages over current combinatorial chemistry drug discovery methodologies, including the following: (i) tagging chemistries are not necessary; (ii) high reaction yields are not required, so that both known and unknown reaction chemistries (with numerous regiochemical and stereochemical outcomes) currently inaccessible by combinatorial chemistry can be utilized to provide extensive small-molecule libraries; and (iii) the Evolutionary Chemistry process also avoids laborious and database-intensive screening steps common in other combinatorial chemistry approaches. The Company's Evolutionary Chemistry technology uses RNA to catalyze reactions in an effort to produce molecules that are difficult to obtain using current combinatorial chemistry techniques. The Company believes that the Evolutionary Chemistry process will be valuable for developing lead compounds and products with potentially improved pharmacokinetics. The Company hopes that this technology will also significantly reduce costs of pharmaceutical discovery and development. The focus of research efforts of the Evolutionary Chemistry group at the Company has been to expand the repertoire of reactions that may be used to form chemically diverse small-molecule libraries. NeXstar Pharmaceuticals' scientists have shown that RNA is capable of catalyzing a carbon-carbon bond-forming reaction important for the assembly of many pharmacophore compounds. In these experiments, modified RNAs, which are proprietary to the Company, were used to facilitate the Diels-Alder reaction, a highly valued organic transformation. The Company also used modified RNA to promote the formation of an amide bond, another reaction commonly used in the assembly of drug candidates. These results indicate that RNA molecules form catalytic binding pockets similar to protein enzymes. The Diels-Alder and amide bond formation reactions represent only a subset of possibly useful reactions for the assembly of drug candidates, and further efforts to prove the applicability of the Evolutionary Chemistry methodology to other classes of reactions, especially those with diverse regiochemical and stereochemical possibilities, are ongoing. COLLABORATIVE RELATIONSHIPS AND LICENSE AGREEMENTS To apply and develop its technologies as widely as possible, NeXstar Pharmaceuticals has entered into and expects to enter into strategic collaborative research agreements, joint ventures and licensing arrangements with pharmaceutical and other health care companies and research institutions. FUJISAWA HEALTHCARE, INC. The Company's rights to market AmBisome are subject to an agreement between the Company and Fujisawa Healthcare, Inc., as successor to Fujisawa USA, Inc. ("Fujisawa"). Under the terms of the agreement, as amended, Fujisawa and the Company co-promote AmBisome in the United States, Fujisawa has sole marketing rights to AmBisome in Canada, and the Company has exclusive marketing rights to AmBisome in the rest of the world. In connection with U.S. sales, Fujisawa purchases AmBisome from the Company at cost; Fujisawa collects all payments from the sale of AmBisome in the U.S., and the Company receives 20% of the gross profits from the sale of AmBisome in the United States. The Company is required to pay royalties to Fujisawa in connection with sales in most significant Asian markets, including Japan. See "--Products and Markets--AmBisome." SUMITOMO PHARMACEUTICALS CO., LTD. NeXstar Pharmaceuticals has licensed the right to develop and market AmBisome in Japan to Sumitomo Pharmaceuticals Co., Ltd. ("Sumitomo"). Under the terms of the license, Sumitomo is required to make payments to the Company if certain clinical and commercial milestones are met and to pay the Company royalties on all Japanese sales of AmBisome. Sumitomo has paid the Company a total of $10 million for the achievement of milestones, including payment of $3.0 million in March 1998 related to 12 the filing of a new drug application for AmBisome in Japan. Under the terms of the license, Sumitomo is also required to make a milestone payment to the Company if AmBisome is approved for sale in Japan. PROLIGO L.L.C. AND PASS: PRODUCT ANCHORED SEQUENTIAL SYNTHESIS In late 1997, the Company established its NeXstar Technology Products division which included the Company's proprietary technology called Product Anchored Sequential Synthesis ("PASS"), a method of synthesizing the oligonucleotides that are the basis for the products being developed using the SELEX process. In July 1998, the Company established Proligo L.L.C., a Delaware limited liability company ("Proligo"), as a wholly-owned subsidiary and transferred all of the assets of the NeXstar Technology Products division to Proligo. On August 15, 1998, the Company sold a 51% interest in Proligo to SKW Americas, Inc. ("SKW") in exchange for $15 million cash and a 49% interest in PerSeptive Biosystems GmbH, a German corporation ("PerSeptive). As a part of the transaction, the Company contributed its interest in PerSeptive and $4.9 million cash to Proligo, and SKW contributed its 51% interest in PerSeptive and $5.1 million cash to Proligo. In addition, SKW will pay the Company $3 million in guaranteed payments and up to $20.5 million in performance-based milestones over the next five years. The Company and Proligo have agreed that Proligo will manufacture oligonucleotides required by the Company at cost plus a fixed percentage. Traditional methods for the manufacture of oligonucleotides are suitable for research-scale production of these compounds, but are severely limited for larger-scale or commercial production. Traditional manufacturing methods use solid phase synthetic methods that are not capable of predictable scale up. Adapting traditional manufacturing methods to a particular oligonucleotide (aptamer) is laborious and costly. The crude product of traditional manufacturing methods is contaminated and requires further purification. The PASS technology is a new method for synthesizing oligonucleotides (including aptamers) which is expected to produce oligonucleotide-based drugs in commercial quantities in a predictable and cost-effective manner. The PASS technology allows for predictable scale-up of oligonucleotide products, using conventional chemical engineering techniques. The PASS technology improves the economics of oligonucleotide synthesis in several ways. The PASS technology uses fewer (costly) monomers in each step needed to construct an oligonucleotide chain. The PASS technology also reduces purification costs associated with oligonucleotide synthesis as a result of the removal of contaminants, using a proprietary product anchoring process, after each monomer is added to the chain. The PASS technology also uses chemical activators to speed up the chemical reactions that assemble monomers into a chain. In addition, the in-process controls and documentation of PASS-manufactured oligonucleotides (not present with traditional manufacturing methods) may prove beneficial in obtaining regulatory approval for oligonucleotide-based products. SCHERING A.G. In 1993, the Company entered into a collaborative research agreement (the "Schering Research Agreement") and license agreement (the "Schering License Agreement") with Schering A.G. Under the Schering Research Agreement, as amended from time to time, Schering A.G. has funded research at NeXstar Pharmaceuticals for the discovery and development of aptamers as IN VIVO diagnostic agents. The level of funding under this agreement has varied over the five year term, from $1.0 million to $2.4 million annually. In March 1999, Schering A.G. agreed to fund $250,000 under the Schering Research Agreement for the first half of 1999, with an option to continue funding an additional $250,000 in 1999 and $500,000 annually thereafter. Under the Schering Research Agreement, NeXstar Pharmaceuticals is developing aptamers for thromboembolic disease diagnosis and tumor diagnosis. 13 Under the Schering License Agreement, Schering A.G. has the right to develop and commercialize the aptamers discovered and developed under the Schering Research Agreement. Schering A.G. has also licensed the rights to aptamers as IN VIVO diagnostic agents or radiotherapeutics. Schering A.G. is required to make milestone and royalty payments to the Company upon commercialization and sale of any products developed under the collaboration with the Company. The Schering License Agreement also permits the Company to develop and commercialize aptamers discovered under the Schering Research Agreement outside the field of IN VIVO diagnostic agents or radiotherapeutics, subject to royalty payments to Schering A.G. GLAXO WELLCOME, INC. AND GLAXO GROUP LIMITED In May 1998, the Company entered into a three-part collaboration with Glaxo Wellcome, Inc. and Glaxo Group Limited (together, "Glaxo"), consisting of a license agreement (granting the Company exclusive rights to lurtotecan, a proprietary Glaxo compound), a research license (granting Glaxo rights to use the SELEX process for target validation) and a stock purchase agreement. Pursuant to the Glaxo License Agreement, Glaxo granted to the Company the exclusive right to develop and commercialize Glaxo's proprietary topoisomerase I inhibitor, lurtotecan, a comptothecin derivative and potent anti-cancer compound. The Company is developing a liposomal formulation of lurtotecan, designated by the Company as NX211 and has planned three Phase I clinical trials for NX211, the first of which has begun in the Netherlands. The Company expects to submit an IND in the United States in the second quarter 1999 and expects to commence a Phase I trial in the United States prior to the end of the second quarter 1999. See "--Products and Markets--NX211". The Glaxo License Agreement requires the Company to make milestone payments and pay royalties to Glaxo at various stages of development and commercialization of NX211. The first such milestone payment is due upon initiation by the Company of a Phase III clinical trial. Additional milestones are payable if NX211 is approved for sale. Under the Glaxo License Agreement, Glaxo has the option to participate with the Company in the continued development and commercializatin of NX211 for one or more territories throughout the world, including the United States, Europe and Japan. Such option may be exercised within 60 days after the development of the first Phase III protocol or the preparation of a Phase II study report, whichever is later. If Glaxo exercises the option, Glaxo and the Company must negotiate and execute a development and marketing agreement for the joint development and promotion of NX211 in the relevant territories. The milestone payments and royalties payable by the Company to Glaxo under the Glaxo License Agreement will be reduced or eliminated upon Glaxo's option exercise, depending on the territories in which Glaxo has elected to participate. In connection with the Company's collaboration with Glaxo and pursuant to the SELEX Research Agreement, dated May 27, 1998, between the Company and Glaxo (the "Glaxo Research Agreement"), the Company granted to Glaxo a five year non-exclusive worldwide license to practice the SELEX technology for target validation. The Glaxo Research Agreement includes development rights granting Glaxo, in certain situations, the right to develop and commercialize the aptamers discovered in the course of its research. If Glaxo enters into a development license for an aptamer discovered under the Glaxo Research Agreement, Glaxo will be required to pay license fees, milestone payments and royalties to the Company at various states of development and commercialization of the aptamer. Pursuant to a Stock Purchase Agreement, dated May 27, 1998, between Glaxo and the Company and in connection with the Glaxo License Agreement and Glaxo Research Agreement, Glaxo purchased 962,117 shares of Company Common Stock for $10 million cash. Glaxo was granted certain registration rights in connection with the purchase of the Company Common Stock. 14 UNIVERSITY OF COLORADO NeXstar Pharmaceuticals has a significant ongoing collaborative relationship with the University of Colorado at Boulder ("CU") relating to the SELEX process technology. The relationship is formally with University Research Corporation ("URC"), a for-profit, wholly owned subsidiary of the University of Colorado Foundation, Inc. URC is designed to serve as the corporate vehicle for commercial exploitation of inventions by the CU faculty. URC has assigned to the Company all of URC's present and future rights to (i) inventions falling within the scope of the claims contained in issued patents and pending patent applications for the SELEX process technology, (ii) improvements to such technology made or discovered by researchers at CU, (iii) oligonucleotides or other molecules that are derived through the application of such technology by researchers at CU, (iv) results of certain sponsored research and (v) computer software related to such technology. In connection with the rights assigned by URC to the Company, URC is to receive certain royalties on the Company's net sales of products derived from the SELEX process and on royalties received by the Company from non-affiliates. MARKETING NeXstar Pharmaceuticals has established marketing subsidiaries in the United Kingdom, Germany, Italy, Spain, France, Portugal, The Netherlands and Australia and a marketing branch operation in Greece to promote and sell its existing products. In addition, the Company has a domestic sales and marketing organization to sell DaunoXome and to co-promote AmBisome in the United States. NeXstar Pharmaceuticals also has agreements with third-party distributors, including distributors in certain of the countries in which the Company has marketing operations, to promote, sell and distribute its products. In certain countries, AmBisome and DaunoXome can be prescribed by individual physicians who request the products, even though a regulatory approval in that country has not yet been obtained. In those cases, the Company's marketing professionals provide information and assistance requested by physicians. Each of the Company's marketing subsidiaries is headed by a general manager who oversees the Company's operations in the market(s) served by the subsidiary. The subsidiaries assist in conducting Phase IV clinical trials in the countries in which they are located and many of the major subsidiaries have a physician employed by them to assist in conducting these clinical trials. The Company also has established an administrative infrastructure in Europe, including accounting and human resources support, to assist in its European marketing operations. MANUFACTURING The Company is manufacturing AmBisome in commercial quantities in two separate, but adjacent, facilities in San Dimas, California (the "Manufacturing Facilities"). The Medicines Control Agency of the United Kingdom (the "MCA") has approved the manufacture of AmBisome for commercial distribution from both Manufacturing Facilities. The FDA has also approved a new drug application listing both Manufacturing Facilities for the manufacture of AmBisome for U.S. distribution. While the Company currently uses internal capacity to perform lyophilization, it also uses third parties to fill and lyophilize commercial batches as alternative contract manufacturing suppliers. There can be no assurance that problems with such lyophilization vendors will not occur and have an adverse effect on the Company's results of operations. The Company currently has regulatory approval from the MCA to manufacture DaunoXome for commercial distribution at both Manufacturing Facilities, and from the FDA to manufacture and distribute DaunoXome from only one of the Manufacturing Facilities. The Company intends to seek FDA approval to manufacture DaunoXome at its other Manufacturing Facility. There can be no assurance that the Company will be successful in obtaining the regulatory approvals which it is seeking or may seek in connection with its manufacturing facilities. 15 To import its products into the European Union (the "EU"), the Company must obtain quality control release of its products in the EU. The Company owns a manufacturing facility in Dublin, Ireland. The Company performs quality control release, packaging and distribution from this facility for distribution in the EU and elsewhere. NeXstar Pharmaceuticals concentrates on developing internal manufacturing capabilities for its products at the same time as it develops those products. While each liposomal formulation requires unique variations in process methods, NeXstar Pharmaceuticals believes that it possesses the necessary technical skills to design and implement scaled-up manufacturing capabilities for the liposomal products it is currently developing. However, there can be no assurance that the Company will be able to achieve such capabilities in connection with new liposomal products or will be able to cost effectively manufacture any compounds derived using the Company's non-liposomal technologies. All of the component steps of the manufacturing process use equipment that is commercially available and that can be obtained in larger sizes if required. Currently, high quality amphotericin B, daunorubicin HCl and high quality cholesterol, each of which is used in the Company's manufacture of liposome products, are obtained only from single approved suppliers. Additional suppliers of each of these components are presently under evaluation. In the event that the materials become unavailable from their respective suppliers, the Company believes that alternative supplies of such materials are or will become available at reasonable prices. Other lipid materials and other raw materials are available from a number of suppliers, and NeXstar Pharmaceuticals believes that supplies are adequate for the foreseeable future. COMPETITION Generally, competition in the pharmaceutical field is based on such factors as product performance, safety, acceptance by doctors, patient compliance, patent protection, ease of use, price, distribution, marketing and adaptability to various modes of administration. The Company's products compete or may compete with new chemical substances as well as improved delivery of current drugs. The Company's products and potential products are in various stages of development and no assurance can be given that any of these products or potential products will be sufficiently more effective than existing treatment alternatives to generate meaningful commercial demand. NeXstar Pharmaceuticals anticipates that it will face increased competition in the future as new products enter the market and advanced technologies become available. Many of the Company's existing or potential competitors have substantially greater financial, technical and human resources than NeXstar Pharmaceuticals and may be better equipped to develop, manufacture and market products. In addition, many of these companies have extensive experience in research, preclinical testing and human clinical trials; obtaining FDA and other regulatory approvals; and manufacturing and marketing their products. As a result, these companies may develop and introduce products and processes more rapidly than, and competitive with or superior to, those of NeXstar Pharmaceuticals. There can be no assurance that existing products or new products developed by the Company will be more effective than any that may be developed by the Company's competitors. Competitive products may render the Company's technology and products obsolete or noncompetitive. In markets in which AmBisome has been approved as a primary therapy, it competes against traditional amphotericin B, which is made by Bristol-Myers Squibb Company, and the Company expects to increasingly face competition from other antifungal products, including those produced or currently under development by major pharmaceutical companies, such as Pfizer, Inc. In addition, there are a number of other companies that are focused on the development of lipid-based products, some of which have lipid-based amphotericin B products that have been approved in the United States and throughout Europe. These products compete against AmBisome as both primary and secondary therapy and have been offered at prices that are less than AmBisome's price. Other drugs have been approved, or are awaiting approval, for the treatment of KS in the U.S. and Europe, including one lipid-based anticancer drug, and these drugs 16 compete or are expected to compete with DaunoXome. If the Company is successful in broadening the indications for DaunoXome, it will face competition from a number of oncology drugs. Some of the drugs, which currently or may in the future compete with DaunoXome, are owned by companies with substantially greater resources than the Company's. The Company believes that earlier entry into a market is an advantage for a new drug, but it also believes that therapeutic index and cost-effectiveness are important to a product's success. Ultimately, therefore, the Company believes that its products and those of its competitors, whether or not lipid-based, will compete on their merits in the markets where they are approved. PATENTS, TRADE SECRETS AND LICENSES Patents and other proprietary rights are important to the Company's business. NeXstar Pharmaceuticals also relies upon trade secrets, know-how, continuing technological innovations and licensing opportunities to develop and maintain its competitive position. NeXstar Pharmaceuticals actively seeks patent protection both in the U.S. and internationally and has a portfolio of patent and license rights related to its products and technologies. The patents and patent applications primarily relate to the Company's liposome products and liposome technology and various aspects of its SELEX and Evolutional Chemistry processes. NeXstar Pharmaceuticals has licensed certain technology from and pays royalties to the Regents of the University of California in connection with the production and sale of AmBisome. The royalty rate varies depending on the amount of revenues from the commercial sale of AmBisome, among other things. Currently, the royalty rate averages less than 1% of net sales. In addition, NeXstar Pharmaceuticals makes quarterly and annual payments to The Liposome Company, Inc. ("TLC") in connection with the settlement of litigation involving the Company and TLC. See "Management's Discussion and Analysis of Financial Condition and Results of Operations--Results of Operations." Pursuant to the settlement agreement between the two parties, TLC agreed that it would not sue the Company in connection with the worldwide production and sale of AmBisome. NeXstar Pharmaceuticals has also licensed technology from and pays royalties to The City of Hope National Medical Center in connection with the production and sale of DaunoXome. The royalty rate varies depending on the amount of revenues from the commercial sale of DaunoXome. European and Japanese patents have a defined term following grant during which opposition to the grant can be filed. Both NeXstar Pharmaceuticals and certain of its competitors have filed such oppositions against each other with respect to certain patents in Europe and Japan. NeXstar Pharmaceuticals has also opposed the grant of European and Japanese patents of TLC relating to certain active drug loading techniques that the owner of this patent or application could claim are used in the manufacture of products such as DaunoXome. Although patents are enforceable from the date of issuance and presumed to be valid, future litigation or reexamination proceedings regarding the enforcement or validity of the Company's existing patents or future patents, if issued, could result in a ruling adverse to the Company that could invalidate such patents or substantially reduce the scope of the protection afforded by such patents. As to any issued patent or patent application, it is also possible that the U.S. Patent and Trademark Office ("USPTO") could declare an interference proceeding to determine, INTER ALIA, priority of inventorship between applications claiming the same invention. An adverse ruling in any such interference proceeding could result in cancellation of claims in issued patents or patent applications, limitations on the scope of issued patents or claims in patent applications or in the awarding of the rights to third parties participating in such interference. If the Company elects to, or is required to participate in, interference proceedings declared by the USPTO, substantial cost to the Company could result. The Company also relies on trade secrets, proprietary know-how and continuing technological innovation which it seeks to protect with confidentiality agreements with its collaborators, employees and 17 consultants. There can be no assurance that these agreements will not be breached, that the Company will have adequate remedies for any breach or that the Company's trade secrets and proprietary know-how will not otherwise become known or be independently discovered by competitors. Under certain of the Company's research and development agreements, inventions discovered in certain cases become jointly owned by the Company and the corporate partner or research institution and in other cases become the exclusive property of the Company or the corporate partner or research institution. Disputes may arise with respect to ownership of any such inventions. GOVERNMENT REGULATION The production and marketing of the Company's products, developed through the Company's technologies, and its ongoing research and development activities, including its preclinical studies and clinical trials, are subject to regulation by numerous federal, state and local governmental authorities in the United States and by similar regulatory agencies in other countries where the Company tests and markets, or intends to test and/or market, its current or potential products. There can be no assurance that the Company will obtain further regulatory approvals to conduct clinical trials or to market its products, or that the Company will obtain regulatory approvals to conduct clinical trials or to market products developed in the future, if any, on a timely basis. Prior to marketing any drug developed by the Company or marketed under license, the Company must undergo an extensive regulatory approval process by the FDA and comparable regulatory authorities in foreign countries. The regulatory process, which includes preclinical testing and clinical trials of each compound to establish its safety and efficacy, can take many years and require the expenditure of substantial resources. Before obtaining regulatory approvals for the commercial sale of any of its products under development, the Company must demonstrate through preclinical studies and clinical trials that the product is safe and efficacious for use in each target indication. The results from preclinical animal studies and early clinical trials may not be predictive of results that will be obtained in large scale testing, and there can be no assurance that the Company's clinical trials will demonstrate the safety and efficacy of any products or will result in marketable products. A number of companies in the biotechnology industry have suffered significant setbacks in advanced clinical trials, even after experiencing promising results in early animal and human testing. In addition, the rate of completion of the Company's clinical trials is dependent upon, among other factors, the rate of patient enrollment. Patient enrollment is a function of many factors, including the size of the patient population, the nature of the protocol, the Company's ability to manage the clinical trial, the proximity of patients to clinical sites and the eligibility criteria for the study. Several factors, such as delays in planned patient enrollment, may result in increased costs and delays or termination of clinical trials prior to completion, which could have a material adverse effect on the Company. Preclinical studies must also be conducted in conformity with the FDA's good laboratory practice regulations. Clinical trials generally must meet requirements for institutional review board oversight and informed consent, as well as regulatory agency prior review, oversight and good clinical practice requirements. The procedure for obtaining regulatory approval for a new human pharmaceutical product involves many steps. Initially, NeXstar Pharmaceuticals conducts animal studies to secure data relevant to potential safety and efficacy. Based on the data from these animal studies, NeXstar Pharmaceuticals files applications to conduct clinical trials of the products in humans. Such applications, known as Investigational New Drug applications in the United States, must be made in each country in which NeXstar Pharmaceuticals proposes to conduct clinical trials. Once such applications have been approved, NeXstar Pharmaceuticals can commence clinical trials. Clinical trials are generally conducted in three phases. Phase I trials are designed to test basic human safety. Phase II trials test dosage and involve a detailed evaluation of human efficacy and safety. Phase III trials involve large-scale evaluation of general efficacy and safety and a comparison with existing alternative therapies for the treatment of a specific indication. To the extent possible, NeXstar Pharmaceuticals 18 designs such clinical trials to meet the standards of both foreign and U.S. regulatory authorities, but there can be no assurance that the authorities in any country will be satisfied with the conduct of any particular clinical trial. Data obtained from preclinical and clinical activities are susceptible to varying interpretations which could delay, limit or prevent regulatory approval. In addition, delays or rejections may be encountered based upon changes in the policies of regulatory authorities for drug approval during the period of product development and regulatory review of each submitted new drug application or product license application. The Company may be required to demonstrate that the proposed product represents an improved form of treatment over existing therapies. There can be no assurance that, even after such time and expenditures, regulatory approvals will be obtained for any drugs developed or discovered by the Company or its collaborative partners utilizing the Company's technologies. If the results of its clinical trials indicate it is appropriate, NeXstar Pharmaceuticals may file for regulatory approvals of the product. Such filings are known as New Drug Applications in the United States and as Product License Applications in Europe. Prior to making any filing, the Company determines whether it has sufficient data for such filing and whether the Company is likely to generate sufficient revenues in order to justify the time and expense of such filing. When a regulatory authority approves the sale of a drug, regulations also govern the manufacturing process and marketing activities, including the types of information that the Company may provide to health care providers, and may require post-marketing testing and surveillance programs to monitor the effects of the Company's products. Moreover, if regulatory approval of a drug is granted, such approval is likely to entail limitations on the indicated uses for which it may be marketed. Further, even if such regulatory approval is obtained, a marketed drug and its manufacturer are subject to continual review, and discovery of previously unknown problems with a product or manufacturer may result in restrictions on such product or manufacturer, including withdrawal of the product from the market. During the first quarter of 1997, the Company received and responded to an FDA warning concerning certain promotional materials supplied by the Company in connection with the sale of DaunoXome in the U.S. While the Company does not believe that the actions which it has taken in connection with the warning letter will adversely affect the operations of the Company, no assurance can be given. Regulatory approval of prices is generally required in most foreign countries. In particular, certain countries will condition their approval of a product on the agreement of the seller not to sell that product for more than a certain price in that country and in the past have required price reductions after or in connection with product approval. There can be no assurance that regulatory authorities in the future will not establish lower prices or that any regulatory action reducing the price of AmBisome or DaunoXome in any one country will not have the practical effect of requiring the Company correspondingly to reduce its prices in other countries. There can be no assurance that the resulting prices would be sufficient to generate an acceptable return on the Company's investment in its products. NeXstar Pharmaceuticals is aggressively pursuing worldwide commercialization of its products. In some countries, regulatory procedures allow for product sales under certain circumstances before final regulatory approvals are obtained. The Company has submitted and will continue to submit requests for approval of AmBisome and DaunoXome with regulatory authorities worldwide. Regulatory procedures and review times vary from country to country. There can be no assurance that any of the Company's pending applications for approvals will be granted or that regulatory actions will be taken in a timely fashion. The Company has received an approved shelf life for DaunoXome of 52 weeks in the United States and 40 weeks in Canada and most European countries. While the Company is attempting to obtain longer shelf lives than those currently approved in Canada and Europe, there can be no assurance that the extension of any approved shelf lives will be approved by any regulatory authority. The Company in the past has replaced, and in the future expects, under certain circumstances, to replace, vials of DaunoXome with expired shelf lives and the likelihood that customers would seek to return material amounts of 19 DaunoXome to the Company because of the expiration of its shelf life may be increased if shelf lives longer than those currently approved are not obtained. In addition, the Company's manufacturing facilities are subject to inspection and regulation by U.S., foreign and state regulatory agencies. The Company's facilities in San Dimas, California have been inspected by the FDA, the MCA and the State of California. These agencies may reinspect at any time, and other countries' regulatory authorities may inspect the Company's facilities as well. Furthermore, although the Company's current pharmaceutical products do not require export licenses, there can be no assurance that export licenses will not be required in the future. See "--Manufacturing." Failure to comply with applicable regulatory requirements can, among other things, result in fines, suspension of regulatory approvals, product recalls, seizure of products, imposition of operating restrictions and criminal prosecutions. Further, FDA policy or similar policies of regulatory agencies in other countries may change and additional government regulations may be established that could prevent or delay regulatory approval of potential products. The Company's research and development involves the controlled use of hazardous materials, chemicals, viruses and various radioactive compounds. Although the Company believes that its safety procedures for handling and disposing of such materials comply with the standards prescribed by state and federal regulations, the risk of accidental contamination or injury from these materials cannot be completely eliminated. In the event of such an accident, the Company could be held liable for any damages that result and any such liability could exceed the resources of the Company or otherwise adversely affect the Company. NeXstar Pharmaceuticals is subject to numerous environmental and safety laws and regulations, including those governing the use of hazardous materials. In June 1995, the Company was contacted by the U.S. Environmental Protection Agency (the "EPA") informing the Company that it is a potentially responsible party relating to the disposal of the Company's waste products by a third party at a hazardous waste disposal facility. The Company has complied with all requests by the EPA relating to this matter and believes that its liability with respect to this matter will be minimal; however, there can be no assurance that this matter or any violation of, or the cost of compliance with, environmental and safety laws and regulations will not adversely impact the Company's operations. EMPLOYEES As of February 28, 1999, NeXstar Pharmaceuticals and its subsidiaries employed 488 persons on a full-time basis, of whom 292 were engaged in research, development, clinical research, medical and regulatory affairs, quality control and manufacturing and 196 were engaged in marketing, finance and administration. There can be no assurance that NeXstar Pharmaceuticals will be able to continue to attract and retain qualified personnel in sufficient numbers to meet its needs. NeXstar Pharmaceuticals believes that it maintains good relations with its employees. AGREEMENT AND PLAN OF MERGER WITH GILEAD SCIENCES, INC. On February 28, 1999, The Company entered into (i) an Agreement and Plan of Merger (the "Merger Agreement") by and among Gilead, Gazelle Acquisition Sub, Inc. ("Sub") and the Company, pursuant to which Sub will be merged into the Company and the Company will survive as a wholly owned subsidiary of Gilead (the "Merger") and (ii) a Stock Option Agreement (the "Option Agreement"), by and between Gilead and the Company. Pursuant to the terms of the Merger Agreement, each issued and outstanding share of Company stock, par value $.01 per share ("Company Common Stock"), will be converted into the right to receive that number of shares of Gilead common stock, par value $.001 per share ("Gilead Shares") equal to the "Exchange Ratio". The "Exchange Ratio" equals 0.425, provided, however, that if the Gilead Share Value (defined as the average of the closing prices of the Gilead Shares as reported on the Nasdaq National Market for the 20 consecutive trading days ending on the third trading day preceding the date on which the 20 stockholders of the Company vote on the Merger at the special meeting of the Company's stockholders called to approve and adopt the Merger Agreement and the Merger) is (i) less than $36.47, then the Exchange Ratio shall be equal to the lesser of 0.50 or a fraction having a numerator equal to $15.50 and having a denominator equal to the Gilead Share Value, or (ii) greater than $45.88, then the Exchange Ratio shall be equal to the greater of 0.3786 or a fraction having a numerator equal to $19.50 and having a denominator equal to the Gilead Share Value. Cash will be paid in lieu of fractional shares. The Merger is subject to several conditions, including that it be approved by the stockholders of both the Company and Gilead. The Merger will be accounted for as a "pooling of interests" and the exchange of shares will be tax free to the holders of Company Common Stock. In connection with the execution of the Merger Agreement, (a) the Company granted to Gilead an option to purchase up to 19.9% of Company Common Stock under certain circumstances, and (b) each Director of the Company, Warburg, Pincus Investors, L.P. and Warburg, Pincus Capital Partners Liquidating Trust, each in his, or her or its capacity as a stockholder of the Company, agreed to vote his, her or its respective shares of Company Common Stock in favor of the approval and adoption of the Merger Agreement and the Merger. If, however, the Gilead Share Value drops below $27.00, the obligation to vote such shares in favor of the Merger becomes terminable. ITEM 2. PROPERTIES The Company's corporate headquarters, including its principal executive offices, are located in Boulder, Colorado. The Company subleases a facility of approximately 32,000 square feet of office space (the "Subleased Office Space"), which is being used as administrative offices and leases approximately 60,000 square feet of space (the "Research Facilities"), which is being used as research laboratories and administrative offices. The sublease for the Subleased Office Space expires in July 2003. The lease for the Research Facilities expires in October 2001, but can be renewed at the option of the Company for two successive five-year periods. NeXstar Pharmaceuticals also occupies a facility in San Dimas, California (the "650 Facility") under a noncancelable operating lease which expires in May 2003 and has two five-year renewal options. The 650 Facility provides 51,500 square feet of space and houses research and development activities, manufacturing and certain administrative functions. The 650 Facility has been inspected by the State of California for compliance with "current Good Manufacturing Practices" and is licensed by the State of California for pharmaceutical manufacturing. The license is renewable annually. The 650 Facility has been registered for the commercial production of AmBisome and DaunoXome by the MCA and the FDA. The Company also leases a manufacturing facility adjacent to the 650 Facility in San Dimas, California (the "502 Facility"). The lease for the 502 Facility expires in November 2003 and has two five-year renewal options. The 502 Facility provides in excess of 70,000 square feet of space, including approximately 45,000 square feet of manufacturing space, and is the Company's primary injectable pharmaceutical production plant. The MCA has approved the manufacture of AmBisome and DaunoXome at the 502 Facility. The FDA has approved a New Drug Application for the manufacture of AmBisome at the 502 Facility for U.S. distribution, and the Company intends to seek FDA approval of a new drug application listing for the manufacture of DaunoXome at the 502 facility. In addition, the Company owns a 9,700 square foot facility located in Dublin, Ireland, in which the quality control testing, final labeling and packaging are currently being conducted for AmBisome and DaunoXome for the European Union and elsewhere. ITEM 3. LEGAL PROCEEDINGS Both the Company and certain of its competitors have filed oppositions against each other as to patents granted by the European Patent Office and patents granted by the Japanese Patent Office. The 21 Liposome Company, Inc. ("TLC") has patents or patent applications relating to active drug loading techniques that the owners could claim are used in the manufacture of products such as DaunoXome. The Company has opposed the grant of a European and a Japanese patent owned by TLC relating to such loading technology. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS There were no matters submitted to a vote by the Company's security holders during the fourth quarter of the Company's fiscal year ended December 31, 1998. 22 PART II ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS The Company's common stock is traded on the Nasdaq National Market (Symbol: NXTR). The following table sets forth, for the periods indicated, the high and low closing sales prices per share of the Company's common stock as reported on the Nasdaq National Market. HIGH LOW ----- --- 1997: First Quarter................................................................. $ 173/4 $ 10 Second Quarter................................................................ 151/4 91/4 Third Quarter................................................................. 181/2 121/2 Fourth Quarter................................................................ 181/2 105/16 1998: First Quarter................................................................. $ 123/8 $ 10 Second Quarter................................................................ 123/8 91/2 Third Quarter................................................................. 113/16 61/2 Fourth Quarter................................................................ 113/8 711/16 According to the records of the Company's transfer agent, the Company had approximately 463 stockholders of record as of March 17, 1999. Because many of such shares are held by brokers and other institutions on behalf of stockholders, the Company is unable to estimate the total number of beneficial owners represented by these record holders. DIVIDEND POLICY The Company has not declared or paid any cash dividends on its common stock since its inception. The Company does not anticipate paying any cash dividends on its common stock in the next several years. Certain of the Company's bank and building improvement and equipment lease facilities require the Company to maintain financial ratios and levels of cash and/or stockholders' equity which may have the effect of limiting the Company's ability to pay dividends. SALES OF UNREGISTERED SECURITIES All of the Company's sales of unregistered securities during 1998 have previously been reported in the Company's Quarterly Reports on Form 10-Q. ITEM 6. SELECTED FINANCIAL DATA The following selected consolidated financial data are derived from the Consolidated Financial Statements of NeXstar Pharmaceuticals, which have been audited by Ernst & Young LLP, independent auditors. The selected consolidated financial data give retroactive effect to the merger of NeXagen, Inc. and Vestar, Inc. on February 21, 1995, which has been accounted for as a pooling-of-interests. The selected consolidated financial data also include the acquisition of Supragen, Inc., a research-oriented biotechnology company, on September 8, 1995, which has been accounted for using the purchase method of accounting. Certain reclassifications, including adjustments to conform accounting practices, have been made to prior year amounts to agree with the current year presentation. The data should be read in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations" and the Consolidated Financial Statements of the Company and related notes thereto appearing elsewhere in this Report. 23 YEARS ENDED DECEMBER 31, --------------------------------------------------------------- 1998 1997 1996 1995 1994 ----------- ----------- ----------- ----------- ----------- (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS) CONSOLIDATED STATEMENT OF OPERATIONS DATA: Revenues: Product revenues.............................. $ 108,102 $ 89,152 $ 80,153 $ 57,770 $ 43,967 License fees.................................. 3,000 10 7,000 -- -- Royalties..................................... 5,007 671 -- -- -- Collaborative agreements and contracts........ 2,440 2,388 1,548 2,920 4,054 ----------- ----------- ----------- ----------- ----------- Total revenues.................................. 118,549 92,221 88,701 60,690 48,021 Expenses: Cost of goods sold............................ 21,331 19,787 18,320 13,246 8,091 Research and development...................... 52,475 53,015 47,760 37,356 31,595 Selling, general and administrative........... 49,460 45,033 42,933 35,300 22,108 Litigation settlement and related expenses.... 1,267 16,031 2,006 -- -- Purchased research and development............ -- -- -- 11,824 -- Retirement agreement expense.................. -- -- -- -- 4,097 ----------- ----------- ----------- ----------- ----------- Total expenses.................................. 124,533 133,866 111,019 97,726 65,891 ----------- ----------- ----------- ----------- ----------- Operating loss..................................

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OVERVIEW THIS MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS CONTAINS FORWARD-LOOKING STATEMENTS WITHIN THE MEANING OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995 (SEE "SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS" ON PAGE 3). THESE FORWARD-LOOKING STATEMENTS REPRESENT THE EXPECTATIONS OF THE COMPANY'S MANAGEMENT AS OF THE FILING DATE OF THIS FORM 10-K. THE COMPANY'S ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE ANTICIPATED BY THE FORWARD-LOOKING STATEMENTS DUE TO RISKS AND UNCERTAINTIES, INCLUDING THOSE DESCRIBED UNDER "RISK FACTORS" IN PART II OF THIS REPORT AND ELSEWHERE IN THIS FORM 10-K. THE COMPANY'S STOCKHOLDERS AND POTENTIAL INVESTORS SHOULD CONSIDER CAREFULLY THESE RISKS AND UNCERTAINTIES IN EVALUATING NEXSTAR PHARMACEUTICALS' FINANCIAL CONDITION AND RESULTS OF OPERATIONS. NeXstar Pharmaceuticals is an integrated biopharmaceutical company engaged in the discovery, development, manufacture and marketing of proprietary pharmaceutical products to treat life-threatening and other serious oncological, hematological and infectious diseases. The Company markets AmBisome, a liposomal formulation of amphotericin B, for the treatment of life-threatening fungal infections, and DaunoXome, a liposomal formulation of the anticancer agent daunorubicin, which is used as a first line therapy for the treatment of HIV-associated Kaposi's sarcoma ("KS"). The Company currently relies on sales of AmBisome in Europe for a substantial majority of its product revenues and expects sales of AmBisome in Europe to account for a majority of its revenues in 1999. In the second quarter of 1998, AmBisome received French approval and is now approved in every European Union country. In the third quarter of 1997, the United States Food and Drug Administration ("FDA") approved AmBisome for use in the United States as a primary therapy for patients with a low white blood cell count (febrile neutropenia) who have a presumed fungal infection, also known as fever of unknown origin or FUO, or with visceral leishmaniasis and as a secondary treatment for fungal infections that do not respond to amphotericin B treatment. AmBisome has been approved for sale by the regulatory authorities in 38 countries for the treatment of life-threatening fungal infections, including 16 countries in which it has been approved as a primary therapy for some form of fungal infection. DaunoXome has been approved for sale as a primary therapy for KS in 24 countries, including the United States, Canada and all significant Western European markets. The Company continues to conduct clinical trials with AmBisome in a variety of settings with the goal of expanding its uses. The Company is conducting clinical trials with DaunoXome in an attempt to find additional indications and is planning clinical trials of DaunoXome in patients with acute myeloblastic leukemia and chronic lymphocytic leukemia. In addition, the Company is conducting Phase II clinical trials with a third product, the antibiotic MiKasome, a liposomal formulation of amikacin (a potent aminoglycoside antibiotic) in patients with complicated urinary tract infections, cystic fibrosis, nosocomial pneumonia and tuberculosis. The Company recently commenced Phase I clinical trials for NX 211, its liposomal formulation of a topoisomerase I inhibitor, lurtotecan, a camptothecin derivative and potent anti-cancer compound. The Company has discovered several aptamers using the SELEX process, a combinatorial chemistry technology, which are currently in the research and early clinical/preclinical development stages. In 1998, the Company received FDA approval of its Investigational New Drug ("IND") application, and has begun clinical trials for NX1838, its aptamer which binds to vascular endothelial growth factor ("VEGF"). VEGF is a growth factor which is believed to contribute to age-related macular degeneration, the leading cause of adult-onset blindness, by inducing the formation of blood vessels associated with the disease state. The timing of the clinical trials for MiKasome, NX211, and NX1838 may be affected by many factors including, among others, unanticipated delays; unexpected preclinical or clinical trial results, as applicable; 25 and difficulties in enrolling patients. There can be no assurance that the Company will be able to meet the time schedule which it has established for any of its products. NeXstar Pharmaceuticals was formed in 1991 as NeXagen, Inc. On February 21, 1995, the Company was merged with Vestar, Inc., a Delaware corporation founded in 1981, and changed its name to NeXstar Pharmaceuticals, Inc. The merger was accounted for as a "pooling-of-interests". AGREEMENT AND PLAN OF MERGER WITH GILEAD SCIENCES, INC. On February 28, 1999, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which the Company will be acquired through merger (the "Merger") by Gilead Sciences, Inc., a Delaware corporation ("Gilead"). Pursuant to the terms of the Merger Agreement, each issued and outstanding share of Company common stock, par value $0.01 per share ("Company Common Stock"), will be converted into the right to receive that number of shares of Gilead common stock, par value $0.001 per share ("Gilead Shares") equal to the "Exchange Ratio". The "Exchange Ratio" equals 0.425, provided, however, that if the Gilead Share Value (defined as the average of the closing prices of the Gilead Shares as reported on the Nasdaq National Market for the 20 consecutive trading days ending on the third trading day preceding the date on which the stockholders of the Company vote on the Merger at the special meeting of the Company's stockholders called to approve and adopt the Merger Agreement and the Merger) is (i) less than $36.47, then the Exchange Ratio shall be equal to the lesser of 0.50 or a fraction having a numerator equal to $15.50 and having a denominator equal to the Gilead Share Value, or (ii) greater than $45.88, then the Exchange Ratio shall be equal to the greater of 0.3786 or a fraction having a numerator equal to $19.50 and having a denominator equal to the Gilead Share Value. Cash will be paid in lieu of fractional shares. The Merger is subject to several conditions, including that it be approved by the stockholders of both the Company and Gilead. The Merger will be accounted for as a "pooling of interests" and the exchange of shares will be tax free to the holders of Company Common Stock. The Merger is expected to be completed by early summer. The Company anticipates it will incur approximately $6 million in expenses in 1999 associated with the Merger. In October 1998, the Company announced a potential spin-off of its drug discovery business, which if completed would have created a new company to be known as Iterex Technologies, Inc. ("Iterex"). Pending the completion of the Merger, this spin-off will not occur and the Company's drug discovery business will remain part of the Company. In 1998, the Company incurred $664,000 of spin-off related expenses. In the first quarter of 1999, the Company expects to record additional expenses of approximately $400,000 related to the previously planned Iterex spin-off. INTERNATIONAL OPERATIONS, CURRENCY FLUCTUATIONS In connection with a majority of its European sales, the Company prices its products in the currencies of the countries into which they are sold (the "Payment Currencies"), and revenues in the past have been, and in the future could be, adversely affected by currency fluctuations. A significant majority of the Company's manufacturing costs are in U.S. Dollars. Therefore, any decline in the value of the Payment Currencies relative to the U.S. Dollar is likely to negatively impact gross margins for the Company's products because the Company's manufacturing costs would remain approximately the same while its revenue in terms of U.S. Dollars would decline. Sales in Germany, the U.K., Italy and Spain together accounted for 56% of the Company's product sales for the year ended December 31, 1998. The Company prices its products in each of these four countries in the local currency. NeXstar Pharmaceuticals hedges certain of its foreign currency exposures with respect to its outstanding trade accounts receivable and accounts payable through the use of forward contracts. NeXstar Pharmaceuticals does not currently enter into speculative foreign currency transactions and does not write 26 speculative options. In the future, the Company may begin currency hedging in connection with anticipated revenues and expenses and may use options in addition to forward contracts. Such hedging will be done solely for the purpose of protecting the Company from foreign currency fluctuations. The Company recognizes a gain or loss for each forward contract equal to the difference between the contract rate and the market rate on each balance sheet date which is recorded as a selling, general and administrative expense. At present, no deferred accounting is used in connection with the Company's hedging activities. Notwithstanding its hedging activities (which have not always included fully hedging against potential gains or losses), the Company has in the past recognized foreign exchange gains and losses. There can be no assurance that significant gains or losses will not be incurred in the future. RESULTS OF OPERATIONS YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996 PRODUCT REVENUES. Product revenues increased 21% to $108.1 million, 11% to $89.2 million and 39% to $80.2 million in 1998, 1997 and 1996, respectively, primarily due to increased unit sales of AmBisome in European markets. As a result of the U.S. approval of AmBisome in the third quarter of 1997, the Company anticipates that an increasing percentage of its sales during future periods will occur outside of Europe. Sales of DaunoXome, which was initially approved in the U.S. during the second quarter of 1996, totaled $4.7 million, $5.2 million and $3.9 million during 1998, 1997 and 1996, respectively. LICENSE FEES. In the first quarter of 1998, the Company recorded a $3 million milestone payment (less withholding taxes of $300,000) in connection with a licensing agreement with Sumitomo Pharmaceuticals Co., Ltd. ("Sumitomo") pursuant to which Sumitomo is developing and intends to market AmBisome in Japan. In 1996, the Company recorded an initial $7 million licensing fee (less withholding taxes of $700,000) in connection with the Sumitomo license agreement. ROYALTIES. During 1998 and 1997, the Company received royalties of $5 million and $671,000, respectively, primarily in connection with the sale of AmBisome in the U.S. following the third-quarter 1997 approval by the FDA. This amount will increase if the amount of sales of AmBisome in the U.S. increases. COLLABORATIVE AGREEMENTS AND CONTRACTS. Collaborative agreement and contract revenues were $2.4 million, $2.4 million and $1.5 million for 1998, 1997 and 1996, respectively. The increases for 1998 and 1997 were due to an agreement by Schering A.G., in February 1997, to increase its annual funding to the Company to $2.4 million from $1 million in connection with a collaborative research agreement (the "Schering Research Agreement") first entered into in 1993. The decline in 1996 related to the expiration or termination of collaborations between the Company and certain corporate partners. Collaborative agreement and contract revenue fluctuations are generally the result of changes in the number of funded research projects as well as the timing and performance of contract benchmarks. In March 1999, Schering A.G. agreed to fund $250,000 under the Schering Research Agreement for the first half of 1999, with an option to continue funding an additional $250,000 in 1999 and $500,000 annually thereafter. COST OF GOODS SOLD. Cost of goods sold was $21.3 million, or 20% of product revenues, $19.8 million, or 22% of product revenues, and $18.3 million, or 23% of product revenues, in 1998, 1997 and 1996, respectively. The increases in cost of goods sold for 1998 and 1997 were primarily due to increased sales of the Company's products. The decreases in cost of goods sold as a percentage of product revenues for 1998 and 1997 were primarily due to reductions in the average manufacturing cost of products sold by the Company. The decreases in cost of goods sold as a percentage of product revenues were partially offset because of increased sales of AmBisome to Fujisawa at cost. Pursuant to an agreement between the two firms, the Company and Fujisawa co-promote AmBisome in the United States and the Company sells AmBisome to Fujisawa at cost for sale in the United States. In addition, the Company receives 20% of the Fujisawa gross profits from all U.S. sales which the Company records as royalty income. If the Company's 27 unit sales of AmBisome to Fujisawa increase as a percentage of total AmBisome sales, the cost of goods sold as a percentage of revenues is expected to increase. Cost of goods sold consists primarily of raw materials, allocation of overhead, labor and equipment costs and charges associated with services provided by outside vendors. RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses decreased 1% to $52.5 million in 1998 and increased 11% to $53 million and 28% to $47.8 million for 1997 and 1996, respectively. The decrease in 1998 as compared to 1997 is primarily related to certain one-time charges in 1997 including: (i) a charge of $1.1 million for validation expenses related to product scale-up; (ii) an expense of $1.3 million related to the write off of capitalized purchased technology, which the Company had been amortizing over a four-year period, but which the Company has decided not to pursue; and (iii) $622,000 in reorganization expenses related to research and development consolidation activities, including certain staff reductions. These decreases were partially offset by increased 1998 expenses associated with expanded clinical trial activity for the Company's products and additional preclinical spending on drug candidates. In addition, in October 1998, the Company reduced its research and development workforce by 47 employees and recorded a one-time expense of $1.6 million related to severance packages for the discharged employees. The increase in 1997 expenses as compared to 1996 are due to expanded clinical trial activity for the Company's products and additional preclinical spending on aptamer drug candidates developed using the SELEX process. In 1996, the Company had a charge to research and development of $1.2 million in connection with a write down of an investment that the Company held in a biotechnology company, an expense of $1 million in connection with the Company's decentralization of its medical/ regulatory operations in Europe and an expense of $1.2 million in connection with the acquisition of additional laboratory facilities. In 1998, $2.6 million of research expenses was sponsored by third parties, as compared to $2.4 million and $1.2 million in 1997 and 1996, respectively. Research and development expenses consist primarily of salaries and benefits for scientific, medical, regulatory, quality control and pilot manufacturing personnel and consultants; supplies; occupancy costs; and depreciation of laboratory equipment and facilities. As a result of the October 1998 workforce reduction, the Company expects to realize savings in research and development expenses of approximately $2.5 million per year. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and administrative expenses increased 10% to $49.5 million, 5% to $45 million and 22% to $42.9 million, or 46%, 50% and 53% of product revenues, in 1998, 1997 and 1996, respectively. The increase for 1998 is primarily related to (i) increased sales and marketing expenses in Europe in connection with increased AmBisome sales, in particular, expenses associated with the launch of AmBisome in France; (ii) an expense of approximately $760,000 pursuant to a separation agreement between the Company and Patrick J. Mahaffy upon his resignation as President, Chief Executive Officer and Director of the Company in August 1998; and (iii) a one-time expense of $580,000 related to severance packages for 28 selling, general and administrative employees discharged due to the October 1998 workforce reduction. The increase for 1997 primarily related to (a) increased expenses in connection with the continued expansion of the Company's marketing operations and (b) a charge of $309,000 related to a warrant issued in connection with a $15 million revolving line of credit entered into by the Company. The increase for 1996 was primarily due to (x) the expansion of the Company's marketing efforts, in particular, in connection with the launch of DaunoXome in the United States and the continued expansion of the Company's international operations; (y) an expense of $741,000 in connection with the termination of distribution agreements in Australia and France; and (z) an increase of $520,000 in the Company's allowance for doubtful accounts due to an increase in accounts receivable resulting primarily from increased sales of the Company's products. In addition, the Company recognized foreign exchange losses of approximately $269,000, $287,000, and $362,000 in 1998, 1997 and 1996, respectively. As a result of the October 1998 workforce reduction, the Company expects to realize savings in selling, general and administrative expenses of approximately $700,000 per year. LITIGATION SETTLEMENT AND RELATED EXPENSES. The Company reported litigation settlement and related expenses of $1.3 million, $16 million and $2 million for 1998, 1997 and 1996, respectively. The amount for 28 1997 was primarily related to the August 1997 settlement between the Company and The Liposome Company, Inc. ("TLC") in which the two companies agreed to dismiss all legal proceedings in connection with two U.S. patents and their international counterparts held by TLC (the "Patent Litigation"). Under the terms of the settlement agreement, the Company made an initial payment to TLC of $1.75 million and is required to make payments which began in 1998 based on AmBisome sales over the next several years. Because the payments are subject to certain minimum and maximum amounts, the Company recorded accounting charges in 1997 of $11.8 million, of which $10 million represented the net present value of all future minimum payments it is required to make and $1.75 million represented the initial cash payment. Beginning in 1998, the Company is recording an expense each quarter related to the difference between all future minimum payments and the expense recorded in 1997 and is expensing the difference between the minimum and maximum payments, if any. In 1998, these combined expenses totaled $1.3 million. The Company does not expect the difference between its future minimum and maximum payments to TLC to be material. During 1997 and 1996, the Company had $4.2 million and $2 million in additional expenses related to the Patent Litigation, respectively. GAIN ON SALE OF SUBSIDIARY. In 1998, the Company recorded a $22.1 million gain on the sale of its 51% interest (the "Interest") in its newly established subsidiary, Proligo L.L.C., a Delaware limited liability company ("Proligo"), to SKW Americas, Inc. ("SKW"). Proligo was formed in July 1998 and initially consisted of the assets of the Company's NeXstar Technology Products division, a manufacturer of oligonucleotides and specialty chemicals for the pharmaceuticals industry. As payment for the Interest, the Company received $15 million and a 49% interest in PerSeptive Biosystems GmbH, a company in Hamburg, Germany (the "Hamburg Company"), which specializes in the manufacture of nucleoside phosphoramidite monomers. The 49% interest of the Hamburg Company had a fair market value of approximately $5.5 million. In addition, SKW will pay the Company $3 million in guaranteed payments and up to $20.5 million in performance-based milestones over the next five years. As part of the transaction, the Company contributed $4.9 million and its 49% interest in the Hamburg Company to Proligo. SKW contributed $5.1 million and the remaining 51% interest in the Hamburg Company to Proligo. INTEREST INCOME. Interest income was $3.3 million, $2.4 million and $1.8 million in 1998, 1997 and 1996, respectively. Interest income during 1998 and 1997 increased primarily as a result of investing the proceeds from the Company's sale in the third quarter of 1997 of $80 million of 6 1/4% Convertible Subordinated Debentures due 2004 (the "Debentures"). Interest income generally fluctuates as a result of the average amount of cash available for investment and prevailing interest rates. INTEREST EXPENSE. Interest expense was $6.6 million, $4.4 million and $1.6 million in 1998, 1997 and 1996, respectively. The increase for 1998 was primarily due to a full year of interest payable by the Company on the Debentures and additional borrowings in connection with several equipment lease and financing arrangements. The increase for 1997 was primarily due to five months of interest payable on the Debentures and the Company's bank borrowings. EQUITY IN LOSS OF UNCONSOLIDATED AFFILIATE. In 1998, the Company recorded $1.1 million as its equity in the loss from Proligo representing its 49% share of losses from August 15 through November 30, 1998, the Proligo fiscal year end. The Proligo operating loss for December 1998 is approximately $1.6 million, of which the Company will recognize its 49% share (approximately $800,000) in 1999. The loss recorded by Proligo for December 1998 included three months of operating losses for the Hamburg Company due to a change in the Hamburg Company's fiscal year from September 30 to November 30 to conform to Proligo's reporting period. The Company expects to record additional equity in the loss from its investment in Proligo L.L.C. through fiscal year 1999. NET INCOME (LOSS). The Company reported net income for 1998 of $10.9 million (after giving effect to the $22.1 million gain from the sale of the Interest), or $0.39 per basic share and $0.38 per diluted share, compared to net losses of $43.9 million and $23 million, or $1.65 and $0.88 per basic and diluted share, for 1997 and 1996, respectively. 29 LIQUIDITY AND CAPITAL RESOURCES The Company's cash and cash equivalents and marketable securities position at December 31, 1998 was $68.7 million compared to $64.2 million on December 31, 1997. The $4.5 million increase in cash and cash equivalents and marketable securities position was primarily the result of the following: Net income............................................... $10,920,000 Depreciation and amortization............................ 11,164,000 Gain on sale of a majority interest in a subsidiary...... (22,132,000) Other non-cash items..................................... 2,381,000 Working capital.......................................... (3,637,000) ----------- Net cash used in operating activities.................... $(1,304,000) Addition to property, plant and equipment................ (8,281,000) Proceeds from sale of a majority interest in a subsidiary, net of closing costs........................ 14,652,000 Investment in unconsolidated affiliate................... (4,900,000) Payments on short-term borrowings, net................... (5,034,000) Payments on capital lease obligations.................... (2,934,000) Proceeds from issuance of long-term debt and sale-leaseback transactions............................. 4,478,000 Repayments on long-term debt............................. (1,821,000) Proceeds from sale of common stock, net.................. 11,359,000 Other.................................................... (1,755,000) ----------- Total increase in cash and cash equivalents and marketable securities................................ $ 4,460,000 ----------- ----------- The Company invests its cash and cash equivalents and marketable securities in interest-bearing investment grade securities. The Company's accounts receivable balance at December 31, 1998 was $43.6 million as compared to $34.6 million on December 31, 1997. The growth in receivables was primarily due to increased sales of AmBisome and proportionately increased sales of the Company's products in countries in which payments tend to be slower than the average payment periods historically experienced by the Company. Payment practices vary significantly between countries and increased sales in countries in which payments tend to be slower, often as a result of the pace at which governmental entities reimburse the Company's customers, have in the past increased, and in the future may increase, the average length that accounts receivable are outstanding and may increase the financial risk of certain of the Company's customers. The Company continually seeks improvements in its collection process to maximize its cash flow from product sales in a timely manner. As of December 31, 1998, the Company's inventory balance was $11.7 million compared to $14.6 million as of December 31, 1997. The decrease is primarily due to a reduction in the per unit cost of the inventory. For the year ended December 31, 1998, the Company had $4.5 million in proceeds from facilities improvement and capital equipment financing transactions. As of December 31, 1998, no additional amounts were available under agreements relating to the financing of manufacturing equipment, general laboratory and scientific equipment, office equipment, furniture and fixtures and facility improvements. The Company maintains a $10 million unsecured line of credit (the "Credit Agreement") with an average interest rate of 8.0% with a financial institution. Under the terms of the Credit Agreement, the Company is required to maintain certain financial ratios and there are limitations on the Company's ability to incur additional debt or to engage in certain significant transactions. The Credit Agreement, which 30 includes a foreign exchange facility, expires November 1, 1999. As of December 31, 1998, the Company had no borrowings under the Credit Agreement. In May 1996, the Company's Spanish subsidiary entered into an agreement to borrow 500 million Spanish Pesetas with such borrowing being secured by the subsidiary's accounts receivable. In February 1997, the agreement was amended to increase the amount that the subsidiary could borrow to 750 million Spanish Pesetas. On April 1, 1998, the Company's Spanish subsidiary terminated the loan as to new borrowings and the balance of the loan was paid in full in September 1998. The Company does not have any commitments to provide additional funding to Proligo. The Company believes that in the future it may be advisable to augment its cash in order to fund all of its activities, including potential product acquisitions. Therefore, the Company will consider raising cash whenever market conditions are favorable. Such capital may be raised through additional public or private financing, as well as collaborative relationships, borrowings and other available sources. In addition, in the course of its business, the Company evaluates products and technologies held by third parties which, if acquired, could result in the development of product candidates by the Company or which complement technologies currently being developed by the Company. The Company expects from time to time to be involved in discussions with other entities concerning the Company's potential acquisition of rights to additional pharmaceutical products. In the event that the Company acquires such products or third-party technologies, the Company may find it necessary or advisable to obtain additional funding. The Company's future capital requirements will be substantial and will depend on, and could increase as a result of, many factors, including: progress of the Company's research, drug discovery and development programs; whether the Company acquires interests in products currently held by third parties; the results and costs of preclinical and clinical testing of the Company's products, if developed; the time and costs involved in obtaining regulatory approvals; the costs involved in filing, prosecuting and enforcing patent claims; competing technological and market developments; the Company's success in entering into collaborative agreements; changes in collaborative research relationships; the costs associated with potential commercialization of its products, if any, including the development of additional manufacturing, marketing and sales capabilities; the cost and availability of third-party financing for capital expenditures; and administrative and legal expenses. In particular, the Company expects to have significant cash requirements in the near future as a result of, but not limited to, increased clinical studies, which are required in order to expand the indications and markets for the Company's products. There can be no assurance that additional or sufficient financing will be available, or, if available, that it will be available on acceptable terms. If additional funds are raised by issuing equity securities of the Company, dilution to then existing stockholders may result. If adequate funds are not available, the Company may be required to significantly curtail one or more of its research and development programs or commercialization efforts or obtain funds through arrangements with collaborative partners or others on less favorable terms than might otherwise be available. YEAR 2000 ISSUE The "Year 2000 Issue" is the result of computer programs being written using two digits rather than four to define the applicable year. Any of the Company's computer programs or hardware that have date-sensitive software or embedded chips may recognize a date using "00" as the year 1900 rather than the year 2000. This could result in a system failure or miscalculations causing disruptions of operations, including, among other things, a temporary inability to process transactions, send invoices, or engage in similar normal business activities. The Company has substantially completed a review of its internal computer systems and is conducting a review of the external computer systems on which it relies to determine what action will be necessary or appropriate in connection with the Year 2000 Issue. As a result of its review, the Company has determined: 31 It will be required to modify or replace certain portions of its software and hardware, and upgrade certain software so that those systems will properly utilize dates beyond December 31, 1999. The Company presently believes that with modifications or replacements of existing software and certain hardware, the Year 2000 Issue can be mitigated. However, if such modifications and replacements are not made, or are not completed timely, the Year 2000 Issue could have an impact on the efficiencies of the Company. The Company's plan to resolve the Year 2000 Issue involves the following four phases: assessment, planning, testing and implementation and two categories: information technology systems ("IT Systems") and manufacturing and laboratory equipment ("Operating Equipment"). With respect to IT Systems, the completed assessment indicated that most of the Company's significant IT Systems, in particular, the general ledger, billing, and inventory systems, are Year 2000 compliant. This is a result of (a) the newness of the Company's personal and mini-computer systems (most of its date data is stored using four digits for years and the software residing in its embedded chips recognizes correctly the nuances of the upcoming uncommon leap year), (b) the Company's reliance primarily on personal and mini-computers and not on older mainframes for most of its computing needs and (c) the nature of the Company's business (I.E., the Company is neither a consumer nor financial-based business). For the remaining IT Systems exposures, to date, the Company has completed the planning phase and expects to complete software replacement and upgrades no later than June 30, 1999. Once software is replaced or upgraded for a system, the Company begins testing and implementation. These phases run concurrently for different systems. Completion of the testing and implementation phases for all significant systems is expected by July 31, 1999. With respect to Operating Equipment, the assessment indicated that certain software and embedded chips used in certain Operating Equipment may be at risk. For its Operating Equipment exposures, the Company is completing its planning phase. Scheduling and testing of this equipment is more difficult than the testing of the IT Systems; a substantial majority of the testing occured during an annual manufacturing shutdown in December 1998. Once testing is complete, the Company will implement any upgrades or replace any non-compliant software or hardware. Testing and implementation of affected equipment is expected to be complete by September 30, 1999. The Company does not share information systems with any suppliers, subcontractors, customers or other outside parties ("Third-party Entities"). The Company has requested, and will continue to seek, information from Third-party Entities on which it relies, certifying that their computer systems will not negatively affect the Company's operations. The Company currently relies on third-party vendors in connection with much of its payroll and benefits systems. In addition, the Company could be affected by the failure of various governmental entities to appropriately address the Year 2000 Issue. To date, the Company is not aware of any Third-party Entities with a Year 2000 Issue that would materially impact the Company's results of operations, liquidity, or capital resources. However, the Company has no means of ensuring that Third-party Entities will be Year 2000 ready. The inability of Third-party Entities to complete their Year 2000 resolution process in a timely fashion could materially impact the Company. The effect of non-compliance by Third-party Entities is not determinable. The Company will utilize both internal and external resources to reprogram, or replace, test, and implement the software and Operating Equipment for Year 2000 modifications. It is the Company's belief that the costs to the Company as a result of the Year 2000 Issue will be nominal, but no assurance can be given that there will not be some unforeseen issue, in particular, in connection with Third-party Entities' computer systems, that may materially affect the Company's operations. Management of the Company believes it has an effective program in place to resolve the Year 2000 Issue in a timely manner. As noted above, the Company has not yet completed all necessary phases of the Year 2000 program. In the event that the Company does not complete any additional phases, it may affect manufacturing and laboratory efficiencies. The Company has contingency plans for certain critical applications and is working on such plans for others. In addition, disruptions in the economy generally resulting 32 from Year 2000 Issues could also materially adversely affect the Company. The amount of potential liability and lost revenue cannot be reasonably estimated at this time. EURO CONVERSION A single currency called the euro was introduced in Europe on January 1, 1999. Eleven of the fifteen member countries of the European Union adopted the euro as their common legal currency as of that date. Fixed conversion rates between these participating countries' existing currencies (the "legacy currencies") and the euro was established as of that date. The legacy currencies will remain legal tender as denominations of the euro until at least January 1, 2002 (but not later than July 1, 2002). During this transition period, parties may settle transactions using either the euro or a participating country's legacy currency. The Company is still in the process of evaluating the effect, if any, of the euro on its pricing of products in the eleven participating countries. The Company does not expect a material impact on its results of operations from foreign currency gains or losses as a result of its transition to the euro as the functional currency for its subsidiaries based in EU countries.

SPECIAL NOTE: CERTAIN STATEMENTS SET FORTH BELOW CONSTITUTE "FORWARD-LOOKING STATEMENTS" THAT INVOLVE RISKS AND UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS MAY DIFFER MATERIALLY FROM THE RESULTS DISCUSSED IN THE "FORWARD-LOOKING STATEMENTS." SEE "SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS" FOR ADDITIONAL FACTORS RELATING TO SUCH STATEMENTS. DEPENDENCE ON AMBISOME FOR PRODUCT REVENUES. The Company relies on sales of AmBisome for a substantial majority of its product revenues. If demand for AmBisome were to decline, or revenues were to fall, whether by introduction of competitive products or otherwise, the Company's financial results would be adversely affected. Additional regulatory approvals will also be needed to expand the indications for which AmBisome may be marketed in the countries where it is already approved, and those approvals may or may not be obtained. See "Business-- Clinical Trials, Preclinical Trials and Regulatory Status--AmBisome" in Part I of this Report. The Company's only other approved product, DaunoXome, has had limited sales to date and may never achieve significant sales volume. Although the Company will seek to expand the market for DaunoXome by obtaining approvals for indications in addition to Kaposi's sarcoma, the drug may not be effective for the treatment of other diseases and the Company may never obtain additional approvals. See "Business--Clinical Trials, Preclinical Trials and Regulatory Status--DaunoXome" in Part I of this Report. PRODUCT DEVELOPMENT EFFORTS MAY NOT YIELD SUCCESSFUL PRODUCTS. The Company has three potential products that have reached the clinical development stage-- MiKasome, NX1838 and NX211. While the results of preliminary clinical trials for these products have been encouraging, significant additional clinical trials are required. Preliminary results are not necessarily indicative of a successful product for the following reasons: - preliminary results may not be indicative of effectiveness; - further clinical trials may not achieve the desired result; and - further clinical trials may reveal unduly harmful side effects or may show the drugs to be less effective than other drugs or delivery systems for the desired indications. MiKasome, NX1838 and NX211 may not be more effective than existing drugs or other drugs developed in the future, and they may never develop into commercially viable products. See "Business-- Clinical Trials, Preclinical Trials and Regulatory Status" in Part I of this Report. The Company's other potential products that are in the development stage may not be successfully developed for several reasons, including: - the potential products are not shown to be safe and effective; - required regulatory approvals are not obtained; - the potential products are too difficult to develop into commercially viable products; or - the potential products do not obtain market acceptance. DRUG DISCOVERY EFFORTS MAY NOT YIELD DRUG CANDIDATES OR OTHERWISE YIELD COMMERCIALLY SUCCESSFUL DRUGS. A significant portion of the Company's research is focused upon the discovery and development of novel pharmaceuticals based upon oligonucleotides. This drug discovery approach may not result in commercially successful drugs. Although the Company has demonstrated an ability to efficiently identify oligonucleotides that bind with high affinity to and inhibit selected molecular targets, the Company has not 35 successfully demonstrated the effectiveness of such oligonucleotides as drugs. Additionally, the Company has initiated clinical trials for only one oligonucleotide-based product, NX1838. For the Company to successfully develop commercial products from the drug candidates it identifies through the SELEX and Evolutionary Chemistry processes, several challenges must be addressed, including: - demonstrating the effectiveness of identified compounds as drug candidates; - developing and implementing appropriate clinical protocols for identified drug candidates; and - developing manufacturing methods which are efficient, cost-effective and capable of meeting stringent regulatory standards. The Company may be unable to successfully address any of these or other challenges that may arise in the course of its research and development. THE COMPANY MAY NOT SUCCEED IN ITS STRATEGY TO PROVIDE PRODUCTS FOR TREATING OTHER DISORDERS. In addition to developing products based on its liposome, SELEX process and Evolutionary Chemistry technologies, the Company has a longer-term strategy of providing pharmaceuticals to treat patients with cancer, infectious diseases and hematological disorders. The Company may not be successful in developing marketable products in these disease categories and may not have the scientific or financial resources necessary to develop all of the potential drug candidates or technologies which may be discovered or may be acquired. See "Business" in Part I of this Report. CURRENCY FLUCTUATIONS MAY IMPAIR FINANCIAL RESULTS. A substantial majority of the Company's product sales are made in Europe, with 56% of product sales for the year ending December 31, 1998 occurring in the United Kingdom, Germany, Italy and Spain. In most significant European markets, AmBisome and DaunoXome are priced in the currency of the country in which they are sold. Accordingly, the prices of such products in U.S. Dollars will vary as the value of the U.S. Dollar fluctuates against such local currencies or the Euro. Increases in the value of the U.S. Dollar against foreign currencies may reduce the Company's U.S. Dollar return on the sale of its products. In addition, although the Company implements hedging techniques with respect to foreign currency accounts receivable and accounts payable, these techniques do not eliminate the effects of foreign currency fluctuations with respect to anticipated revenues. Therefore, the Company's future results will continue to be affected by foreign currency fluctuations. See "Management's Discussion and Analysis of Financial Condition--International Operations, Currency Fluctuations." THE COMPANY HAS A HISTORY OF OPERATING LOSSES AND WILL REQUIRE FUTURE CAPITAL TO DEVELOP POTENTIAL PRODUCTS. The Company has incurred substantial losses during its history. Although profitability was achieved in 1998, it was due to a one-time gain of $22.1 million, and the Company may not be able to maintain profitability. In addition, the Company's earnings have historically not been sufficient to cover fixed charges from operations. Future capital needs will be substantial, and the Company may be unable to obtain the capital necessary to fund all of its operations. THE COMPANY MAY BE UNABLE TO PROTECT ITS PATENTS AND PROPRIETARY RIGHTS. The patent positions of pharmaceutical and biotechnology firms, including those of the Company, are uncertain and involve complex legal and factual questions, the breadth of claims allowed in patents cannot be predicted. The Company's success will depend to a significant degree on its ability to: - obtain patents and licenses to patent rights; and 36 - operate without infringing on the proprietary rights of others, both in the United States and other countries. The Company intends to continue to file applications as appropriate for patents covering its technologies and any products resulting from the application of these technologies. There is a risk, however, that patents may not issue from any of its applications or that patents may not issue in connection with technology licensed from third parties. Even if patents do issue, there is a risk that the claims allowed will not be sufficient to protect the Company's proprietary rights, that such patents will be challenged, invalidated or circumvented or that the rights granted pursuant to such patents will not provide competitive advantages. The Company's commercial success will also depend in part on not infringing patents or other proprietary rights of third parties. A number of pharmaceutical and biotechnology companies and research and academic institutions have developed technologies, filed patent applications or received patents on various technologies that may be related to the Company's business. In addition, those entities may file applications for or be issued future patents with respect to technology potentially necessary or useful to the Company. Third parties have filed patent applications with claims allegedly covering technologies similar to the basic aspects of our liposomal technology and SELEX process. Some of these technologies, applications or patents may conflict with the Company's technologies and its existing or future patents, if any, or patent applications. Any of these conflicts could limit the scope of the patents that the Company has obtained or may be able to obtain or result in its patent applications failing to issue as patents. In addition, if patents that cover activities are issued to other companies, NeXstar Pharmaceuticals may be unable to obtain licenses to these patents at a reasonable cost, or at all, or be unable to develop or obtain alternative technology. As more patents are issued to third parties, the risk increases that the Company's products may give rise to claims that they infringe the patents of others. See "Business--Patents, Trade Secrets and Licenses" in Part I of this Report. THE COMPANY MAY ENGAGE IN COSTLY LITIGATION RELATED TO PATENTS AND PROPRIETARY RIGHTS. There has been and, in the Company's opinion, will continue to be significant litigation in the pharmaceutical industry regarding patent and other intellectual property rights. Any litigation could consume a substantial portion of the Company's resources regardless of the outcome. The Company and certain of its competitors have filed oppositions against each other as to patents granted by the European Patent Office and patents granted by the Japanese Patent Office. The Liposome Company, Inc. has patents or patent applications relating to active drug loading techniques that the owners could claim are used in the manufacture of products such as DaunoXome. The Company opposed the grant of a European and a Japanese patent owned by The Liposome Company relating to such loading technology. PHARMACEUTICAL MANUFACTURING IS SUBJECT TO EXTENSIVE REGULATION. The manufacture of AmBisome and DaunoXome involves a number of technical challenges and requires implementation of stringent quality control specifications and quality and manufacturing systems required to comply with government regulations. The Company's products can only be manufactured in facilities that have obtained regulatory approval, which can take many months. Any regulatory action taken with respect to the Company's manufacturing facilities due to failure to meet regulatory requirements might adversely affect its results of operations. THE COMPANY RELIES ON A SINGLE MANUFACTURING LOCATION FOR ITS PRODUCTS. The Company's only formulation and manufacturing facilities are in San Dimas, California; although the Company owns a manufacturing facility in Ireland that performs certain quality control testing, labeling and packaging, and the Company uses third parties to fill and lyophilize certain batches of product 37 as alternate contract manufacturing suppliers. In the event of a natural disaster (including an earthquake), equipment failure, strike or other difficulty, the Company may be unable to replace its manufacturing capacity in a timely manner and would be unable to manufacture its products in a manner necessary to fulfill demand. THE COMPANY RELIES ON SINGLE SOURCES OF SUPPLY FOR RAW MATERIALS. The Company relies on single suppliers for high quality amphotericin B, daunorubicin HCl and high quality cholesterol, each of which is used in the manufacture of its liposome products. Additional suppliers of these components are presently under evaluation. If any of these materials becomes unavailable from current suppliers, the Company would be unable to manufacture at least some of its liposome products until alternative sources of supply are obtained. In addition, the substitution of such replacement supplies would require regulatory approval, which may not be obtained. Although the Company believes that alternative supplies of these materials are or will become available at reasonable prices, it cannot be certain. THE COMPANY HAS LIMITED MANUFACTURING EXPERIENCE FOR ITS OLIGONUCLEOTIDE PRODUCTS. While the Company has experience in manufacturing drug products based on liposome technologies, it lacks experience in the manufacture of other pharmaceuticals, including oligonucleotide-based products. In connection with the formation of Proligo, the Company entered into a supply agreement that contemplates purchasing from Proligo oligonucleotide-based products. However, Proligo may not be able to overcome the technological impediments to synthesizing oligonucleotides on a commercial scale. If Proligo is unable to provide product on a timely basis at commercially reasonable rates, the Company would need to develop additional manufacturing facilities or engage a third-party manufacturer on acceptable terms, all of which could adversely affect its ability to conduct preclinical and clinical testing, and the Company would be unable to obtain regulatory approval for or supply commercial quantities of, oligonucleotide-based products. See "Business--Manufacturing," in Part I of this Report. THE COMPANY'S MARKETING STAFF COMPETES WITH LARGE PHARMACEUTICAL COMPANIES. The pharmaceutical industry is highly competitive. The Company's products compete, and products the Company may develop are likely to compete, with products of other companies that currently have extensive and well-funded marketing and sales operations. Because these companies are capable of devoting significantly greater resources to their marketing efforts, the Company's marketing or sales efforts may not compete successfully against the efforts of these other companies'. See "Business--Marketing" and "Business--Competition" in Part I of this Report. PHARMACEUTICAL REIMBURSEMENT PRESSURES MAY IMPAIR FINANCIAL RESULTS. The ability to commercialize the Company's current and future products depends in part on the extent to which reimbursement for the cost of such products and related treatments are available from government health agencies, private health insurers and other third-party payers. Payers are increasingly challenging the price and cost effectiveness of medical products. Significant uncertainty exists as to the reimbursement status of newly approved health care products, and the Company cannot be certain that adequate third-party coverage will be available to obtain satisfactory price levels for its products. Government and other third-party payers are increasingly attempting to contain health care costs by a variety of means, including limiting both the degree of coverage (including limiting payment for off-label uses) and the level of reimbursement for therapeutic products or new indications for therapeutic products. In addition, the Company's ability to sell a product in certain countries may depend on that product being included, or continuing to be included, on a government-approved reimbursement list. If adequate coverage and reimbursement levels are not provided by government and third-party payers for use of 38 existing and potential products, the market acceptance of these products and the Company's financial results would be adversely affected. PRICING PRESSURES MAY IMPAIR FINANCIAL RESULTS. The Company is subject to the risk of governmental regulation of prices, parallel imports and potential price competition. Differing product prices among countries occur in part because many foreign countries require regulatory approval of prices. In particular, some countries will condition their approval of a product on the agreement of the seller not to sell that product for more than a specified price in the country. A regulatory action reducing the price of AmBisome or DaunoXome in any one country may have the practical effect of requiring the Company to correspondingly reduce the Company's prices in other countries. Additionally, the price set for one product in a given country for competitive reasons may affect that product's prices worldwide. The implementation of the Euro may also lead to more unified pricing of products in European countries, resulting in a lower average sales price. Parallel importing between countries compounds these issues. Under European Union laws, the Company is limited in its ability to restrict third-party distributors to sell products in countries outside of their authorized territory when customers from those other countries offer to buy the product from them. Because of these laws, customers may seek to import product from countries with the lowest price, also resulting in lower average sales price. If the Company is successful in developing additional products or obtaining approval for additional indications for its current drugs, it may also face increased price competition from potential competitors, including European-based companies. See "Business--Competition" and "Business--Government Regulation" in Part I of this Report. OPERATIONS DEPEND ON COMPLIANCE WITH GOVERNMENT REGULATIONS. In addition to governmental regulation of the Company's manufacturing facilities, its operations generally depend on compliance with government regulations. See "Business--Government Regulation" in Part I of this Report. PRODUCT LIABILITY CLAIMS MAY INCREASE COSTS. The use of any of the Company's products or potential products in clinical trials and the sale of such products may expose the Company to liability claims. These claims may be made directly by consumers, health care providers, pharmaceutical companies or others. While the Company currently has liability insurance, insurance is expensive and may be difficult (or impossible) to obtain in the future. If liability insurance becomes unobtainable, the Company's ability to clinically test and to market its products could be significantly impaired. Moreover, the amount and scope of any coverage may be inadequate in the event of a successful product liability claim. Additionally, the Company is required by governmental regulations to test its products even after they have been sold and used by patients. As a result of such tests, the Company may be required to, or may determine that it should, recall products already in the market. Subsequent testing and product recalls may increase our potential exposure to product liability claims. INFLUENCE ON CORPORATE ACTIONS BY EXISTING STOCKHOLDER. Affiliates of E.M. Warburg, Pincus & Co., LLC as of March 9, 1999 owned approximately 28.0% of the Company's outstanding common stock, including a warrant exercisable for 125,000 shares of common stock. As a result, Warburg, Pincus may influence the Company's corporate actions, including influencing elections and significant corporate events. One of the Company's directors is a Senior Managing Director of Warburg, Pincus. 39 THE HOLDERS OF THE COMPANY'S OUTSTANDING CONVERTIBLE DEBENTURES HAVE REDEMPTION RIGHTS. If a change in control of the Company were to occur or if the Company's common stock were no longer listed or approved for trading on a national exchange or an over-the-counter market, the holders of the Company's $80 million of 6 1/4% Convertible Subordinated Debentures due 2004 can require a repurchase of the debentures. If either event occurs, the Company may have insufficient cash to repurchase the debentures. See "Management's Discussion and Analysis of Financial Condition and Results of Operations." ITEM 8.

("WP")) are eligible to receive an annual stock option grant under the Company's 1995 Director Option Plan (the "Director Plan").

In addition, each outside director who has served on the Board of Directors for at least six months automatically is entitled to receive an option grant for 5,000 shares of Common Stock on the last business day prior to each annual meeting of stockholders of the Company. The options have a term of ten years, an exercise price equal to 100% of the fair market value of the Common Stock on the date of grant and vest 50% on each anniversary date of the two years following the grant date; provided that, the optionee is still a director of the Company on the date of vesting.

Options for up to 500,000 shares of Common Stock have been reserved for issuance under the Director Plan. In 1998, each of Dr. Baldeschwieler, Dr. Hirsh, Dr. Hemberger and Mr. Kennedy received an option grant for 5,000 shares of Common Stock.

Mr. Mahaffy will continue to consult to the Company through May 21, 1999 at the request of the Company and will be reimbursed for his out-of-pocket expenses. The Company also agreed to continue Mr. Mahaffy's medical benefits under the Company's health plans and pay the premiums for a $500,000 life insurance policy during the Salary Continuation Period. The Separation Agreement terminated and superseded the Employment Agreement between the Company and Mr. Mahaffy dated May 1992.

The Company can terminate Dr. Gold's employment (i) in the event of physical or mental incapacitation, (ii) if Dr. Gold joins the faculty of an academic institution other than CU or (iii) with or without cause. If Dr. Gold's employment is terminated pursuant to clause (i) above, he will be entitled to receive severance pay for the balance of the term of his employment agreement at the rate of 75% of his salary at the time his employment is terminated, reduced 47 by applicable payroll taxes and the amount he receives during such period under any disability insurance policy or plan maintained by the Company or under Social Security or similar laws. If the Company terminates Dr. Gold's employment without cause, Dr. Gold will be entitled to receive severance pay for the balance of the term of the employment agreement at the rate of 100% of his salary in effect at the time his employment is terminated, reduced by applicable payroll taxes. If the Company terminates Dr. Gold's employment for cause or pursuant to clause (ii) above, then Dr. Gold will not be entitled to receive any severance pay.

On February 8, 1999, the Company entered into change-in-control agreements (the "Change in Control Agreements") with certain members of senior management, including Mr. Caracciolo, Dr. Eley, Mr. Hart, and Dr. Onetto. Pursuant to the terms of the Change in Control Agreements, in the event there is a change in control of the Company and either (a) such officer's employment is terminated without cause, (b) the functions and responsibilities of such officer's job are substantially diminished, or (c) the officer is required to relocate his or her place of residence, then such officer shall receive severance pay equal to 12 months of his or her base salary, continue to receive coverage under the Company's health benefit plans for a period of 12 months and receive outplacement services.

HART Financial Officer - ------------------------------ (Principal Financial March 19, 1999 Michael E. Hart Officer and Principal Accounting Officer) 58 REPORT OF INDEPENDENT AUDITORS The Board of Directors and Stockholders NeXstar Pharmaceuticals, Inc. We have audited the accompanying consolidated balance sheets of NeXstar Pharmaceuticals, Inc. as of December 31, 1998 and 1997, and the related consolidated statements of operations, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 1998. Our audits also included the financial statement schedule listed in the index at Item 14(a). These financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits. We did not audit the financial statements of Proligo L.L.C., a limited liability company, the investment in which is reflected in the accompanying consolidated financial statements using the equity method of accounting. The investment in Proligo L.L.C. represents 5.4% of consolidated total assets at December 31, 1998, and the Company's equity in the net loss of Proligo L.L.C. is $1,101,000 in 1998. The 1998 financial statements of Proligo L.L.C. have been audited by other auditors whose report has been furnished to us; insofar as our opinion on the 1998 consolidated financial statements relates to data included for Proligo L.L.C., it is based solely on their report. 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 and the report of other auditors provide a reasonable basis for our opinion. In our opinion, based on our audits and the report of other auditors, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of NeXstar Pharmaceuticals, Inc. at December 31, 1998 and 1997, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 1998, in conformity with generally accepted accounting principles. Also, in our opinion, the related 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. ERNST & YOUNG LLP Denver, Colorado March 1, 1999 F-1 REPORT OF INDEPENDENT ACCOUNTANTS To the Board of Directors and Members of Proligo LLC: In our opinion, the accompanying consolidated balance sheet and the related consolidated statements of operations, members' equity and of cash flows present fairly, in all material respects, the financial position of Proligo L.L.C. and its subsidiaries at November 30, 1998, and the results of their operations and their cash flows for the period from August 15, 1998 through November 30, 1998, in conformity with generally accepted accounting principles. These financial statements are the responsibility of the Company's management; our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit of these financial statements in accordance with generally accepted auditing standards which 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, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for the opinion expressed above.

F-6 NEXSTAR PHARMACEUTICALS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 1998 NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BUSINESS NeXstar Pharmaceuticals, Inc., a Delaware corporation ("NeXstar Pharmaceuticals" or the "Company") is an integrated biopharmaceutical company engaged in the discovery, development, manufacture and marketing of proprietary pharmaceutical products to treat life threatening and other serious oncological, hematological and infectious diseases. NeXstar Pharmaceuticals was formed in 1991 as NeXagen, Inc. On February 21, 1995, the Company was merged with Vestar, Inc., a Delaware corporation founded in 1981, and changed its name to NeXstar Pharmaceuticals, Inc. The merger was accounted for as a pooling of interests. On February 28, 1999, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which the Company will be acquired through merger ("the Merger") by Gilead Sciences, Inc., a Delaware corporation ("Gilead"). Pursuant to terms of the Merger Agreement, each issued and outstanding share of Company common stock, par value $.01 per share ("Company Common Stock"), will be converted into the right to receive that number of shares of Gilead Common Stock, par value $.001 per share ("Gilead Shares") equal to the "Exchange Ratio." The Exchange Ratio equals 0.425, provided, however, that if the Gilead Share Value (defined as the average of the closing prices of the Gilead Shares as reported on the NASDAQ National Market for the 20 consecutive trading days ending on the third trading day preceding the date on which the stockholders of the Company vote on the Merger at the special meeting of the Company's stockholders called to approve and adopt the Merger Agreement and the Merger) is (i) less than $36.47, then the Exchange Ratio shall be equal to the lesser of 0.50 or a fraction having a numerator equal to $15.50 and having a denominator equal to the Gilead Share Value, or (ii) greater than $45.88, then the Exchange Ratio shall be equal to the greater of 0.3786 or a fraction having a numerator equal to $19.50 and having a denominator equal to the Gilead Share Value. Cash will be paid in lieu of fractional shares. The Merger is subject to several conditions, including that it be approved by the stockholders of both the Company and Gilead. The Merger will be accounted for as a "pooling of interests" and the exchange of the shares will be tax free to the holders of the Company Common Stock. PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION The accompanying consolidated financial statements include the accounts of the Company and its wholly and majority-owned subsidiaries; significant intercompany transactions have been eliminated. Certain reclassifications have been made to prior year amounts to agree with the current year presentation. ACCOUNTING ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. F-7 NEXSTAR PHARMACEUTICALS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) REPORTING COMPREHENSIVE INCOME Effective January 1, 1998, the Company adopted Financial Accounting Standards Board ("FASB") Statement No. 130, "Reporting Comprehensive Income" ("Statement No. 130"). Statement No. 130 establishes standards for reporting and display of comprehensive income and its components in the financial statements. The adoption of Statement No. 130 in 1998 has no impact on the Company's Consolidated Statements of Operations or Consolidated Statements of Stockholders' Equity. The Company has elected to disclose comprehensive income in the Consolidated Statements of Stockholders' Equity in its annual report and in its notes to Condensed Consolidated Financial Statements for interim financial reporting. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided by the straight-line method over the shorter of the lease term or the estimated useful life, which is as follows: Building............................. 20 years Laboratory and manufacturing equipment.......................... 5-7 years Office furniture and equipment....... 3-7 years Capitalized lease equipment.......... 3-5 years Leasehold improvements............... Shorter of useful life or lease term PATENT AND TRADEMARK COSTS The Company capitalizes certain legal costs associated with applying for patents and trademarks. The Company amortizes these costs over a period of ten years. PRODUCT REVENUES/ACCOUNTS RECEIVABLE Product revenues are recognized upon passage of legal title of the inventory. A substantial majority of the Company's product revenues are export sales of AmBisome primarily through Company subsidiaries and to distributors in Europe. The Company performs credit evaluations of its customers' financial condition and generally has not required collateral. The Company's accounts receivable are predominantly trade receivables, and to date, the Company has experienced only modest losses with respect to the collection of its accounts receivable. In connection with most of its European sales, the Company prices its products in the currencies of the country into which they are sold (the "Payment Currencies"), and revenues in the past have been, and in the future could be, adversely affected by currency fluctuations. A significant majority of the Company's manufacturing costs are in U.S. Dollars. Therefore, any decline in the value of the Payment Currencies relative to the U.S. Dollar is likely to negatively impact gross margins for the Company's products since the Company's manufacturing costs would remain approximately the same while its revenue in terms of U.S. Dollars would decline. FOREIGN CURRENCY TRANSACTIONS AND CONTRACTS Foreign exchange transaction losses included in the Consolidated Statements of Operations in 1998, 1997 and 1996 were $269,000, $287,000 and $362,000, respectively. F-8 NEXSTAR PHARMACEUTICALS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) The Company hedges certain of its foreign currency exposures, with respect to its outstanding trade accounts receivable and accounts payable, through the use of forward contracts. The Company does not currently enter into speculative foreign currency transactions and does not write speculative options. In the future, the Company may begin currency hedging in connection with anticipated revenues and expenses and may use options in addition to forward contracts. Such hedging will be done solely for the purpose of protecting the Company from foreign currency fluctuations. The Company recognizes a gain or loss for each forward contract for the difference between the contract rate and the market rate on each balance sheet date that is recorded as a selling, general and administrative expense. At present, no deferred accounting is used in connection with the Company's hedging activities. Notwithstanding its hedging activities (which have not always included fully hedging against potential gains or losses), the Company has in the past recognized foreign exchange gains and losses. There can be no assurance that significant gains or losses will not be incurred in the future. At December 31, 1998 and 1997, the Company had forward exchange contracts outstanding of $42.3 million and $27.9 million, respectively. These contracts have maturities that do not exceed one year and gains/losses resulting from these contracts net of gains/losses on foreign currency exposures, with respect to the Company's outstanding trade accounts receivable and accounts payable, were not material. The Company does not hedge any balance sheet exposure of its foreign subsidiaries. ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES In June 1998, the FASB issued Statement No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("Statement No. 133"). Statement No. 133 requires recording all derivative instruments as assets or liabilities, measured at fair value. Statement No. 133 is effective for fiscal years beginning after June 15, 1999 and, therefore, the Company will adopt the new requirement effective January 1, 2000. Management has not completed its review of Statement No. 133 and has not yet determined the impact on its financial position or results of operations. RESEARCH AND DEVELOPMENT Expenditures for research and development, including costs related to contract and collaborative agreements, and technology defense costs are charged to operations as incurred. NET INCOME (LOSS) PER SHARE Effective December 31, 1997, the Company adopted FASB Statement No. 128, "Earnings Per Share" ("Statement No. 128"), which replaced the calculation of primary and fully diluted earnings per share with basic and diluted earnings per share. Unlike primary earnings per share, basic earnings per share exclude any dilutive effects of options, warrants and convertible securities. Diluted earnings per share is very similar to the previous fully diluted earnings per share. Earnings per share amounts for all periods presented conform to Statement No. 128. The Company's basic net income (loss) per share is computed using the weighted average number of shares of common stock outstanding. Common share equivalents from stock options and warrants are included in the computation of diluted net income per share for the year ended December 31, 1998. Common share equivalents from convertible securities are excluded from the computation for the year ended December 31, 1998, as their effect is antidilutive. Common share equivalents from stock options, warrants and convertible securities are excluded from the computation of diluted earnings per share for the years ended December 31, 1997 and 1996 as their effect is antidilutive.

FAIR VALUE OF FINANCIAL INSTRUMENTS FASB Statement No. 107, "Disclosure about Fair Value of Financial Instruments," requires disclosures of fair value information about financial instruments for which it is practicable to estimate that value. The Company's financial instruments consist principally of cash and cash equivalents, marketable securities, accounts receivable, certain other non-current assets, forward contracts, short-term borrowings, accounts payable, long-term obligations and convertible subordinated debentures. Management believes the financial instruments' recorded values approximate current values with the exception of the convertible subordinated debentures. The fair value of the convertible subordinated debentures at December 31, 1998 was $69.4 million (such fair value being determined by the average of the bid and asked price set by a market maker for the convertible subordinated debentures) as compared to a carrying value of $80 million. F-10 NEXSTAR PHARMACEUTICALS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 2. MARKETABLE SECURITIES Management determines the appropriate classification of debt securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Available-for-sale securities are carried at fair value with unrealized gains or losses excluded from earnings and reported in other comprehensive income. Realized gains and losses and declines in value judged to be other than temporary are included in income.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 5. INVESTMENT IN UNCONSOLIDATED AFFILIATE On August 15, 1998, the Company sold a 51% interest (the "Interest") in its newly established subsidiary Proligo L.L.C., a Delaware limited liability company ("Proligo"), to SKW Americas, Inc. ("SKW"). Proligo was formed in July 1998 and initially consisted of the assets of the Company's NeXstar Technology Products division, a manufacturer of oligonucleotides and specialty chemicals for the pharmaceuticals industry. As payment for the Interest, the Company received $15 million in cash and a 49% interest in PerSeptive Biosystems GmbH, a company in Hamburg, Germany (the "Hamburg Company"), which specializes in the manufacture of nucleoside phosphoramidite monomers. The 49% interest of the Hamburg Company had a fair market value of approximately $5.5 million. In addition, SKW will pay the Company $3 million in guaranteed payments and up to $20.5 million in performance-based milestones over the next five years. As part of the transaction, the Company contributed $4.9 million and its 49% interest in the Hamburg Company to Proligo. SKW contributed $5.1 million and the remaining 51% interest in the Hamburg Company to Proligo. The Company and Proligo have agreed that Proligo will manufacture oligonucleotides required by the Company at cost plus a fixed percentage. The Company recorded a $22.1 million gain in connection with this sale. The Company accounts for its investment in Proligo using the equity method and the net book value of the investment at December 31, 1998 was approximately $10.3 million. In 1998, the Company recorded $1.1 million as its equity in the loss from Proligo representing its 49% share of losses from August 15 through November 30, 1998, the Proligo fiscal year end. The Proligo operating loss for December 1998 was approximately $1.6 million, of which the Company will recognize its 49% share (approximately $800,000) in 1999. NOTE 6. INVESTMENT IN LIFE SCIENCE ENTERPRISE At December 31, 1996, the Company recorded a $1,241,000 write down to an investment in a life science enterprise accounted for under the cost method due to a permanent decline in value. In June 1997, the Company sold all of its holdings in the enterprise for $2.7 million following that company's initial public offering. As a result of the sale, the Company recorded a loss of $26,000 in 1997. NOTE 7. PURCHASED TECHNOLOGY In 1992, the Company and Vical, Incorporated ("Vical") entered into an agreement under which the Company purchased (for $3,000,000) exclusive rights to develop applications of Vical's lipid conjugate technology for a limited number of applications. This agreement was expanded in 1993 (for an additional $1,500,000) to grant the Company exclusive rights to Vical's entire portfolio of lipid conjugate technologies for all potential therapeutic applications. The cost of such base-core technology was capitalized. Effective January 1, 1995, the Company began amortizing the remaining value of the technology over a four-year period. The Company evaluated the carrying amount of the technology for impairment at least quarterly by, among other things, reviewing the status of applicable ongoing development activities, as well as the progress of patent applications and issuances. In September 1997, the Company determined that it would no longer pursue this technology and expensed the remaining $1.3 million of unamortized purchased technology.

In June 1996, the Company entered into a term loan agreement with a bank for $10 million which was repaid in the third quarter of 1997. NOTE 10. CONVERTIBLE SUBORDINATED DEBENTURES During the third quarter of 1997, the Company sold $80 million of 6 1/4% Convertible Subordinated Debentures due 2004 (the "Debentures") in a private offering to SBC Warburg Inc. and Oppenheimer & Co., Inc. which resold the Debentures to a group of private investors. The Debentures were issued pursuant to an indenture and are convertible into a total of up to 4,740,740 shares of the Company's common stock at $16.875 per share. The Company has reserved 4,740,740 shares of its authorized common stock for shares that may be issued upon conversion of the Debentures. As required by the terms of a registration rights agreement (the "Registration Rights Agreement") entered into by the Company in connection with the sale of the Debentures, the Company filed a "shelf" registration statement registering for resale the Debentures and the shares of common stock into which the Debentures may be converted. The registration statement was declared effective on October 6, 1997. Pursuant to the Registration Rights Agreement, the Company is required to keep the "resale" registration statement effective for up to two years. F-13 NEXSTAR PHARMACEUTICALS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 11. COMMITMENTS AND CONTINGENCIES LEASES AND FINANCING AGREEMENTS The Company has entered into one long-term noncancelable operating lease and one long-term noncancelable operating sublease for office, research and manufacturing facilities in Boulder, Colorado and two long-term lease agreements for office, research and manufacturing facilities in San Dimas, California. The three leases and one sublease contain the following terms: LOCATION TERMINATION DATE RENEWAL OPTIONS - ------------------------- ------------------------- ------------------------- Boulder, CO October 2001 2 5-year terms Boulder, CO July 2003 None San Dimas, CA November 2003 2 5-year terms San Dimas, CA May 2003 2 5-year terms The Company has entered into certain sale-leaseback transactions and related master equipment lease agreements for manufacturing equipment, general laboratory and scientific equipment, office equipment, furniture and fixtures. Title to assets acquired under the lease lines of credit resides with the lessor. The Company has the option to purchase the assets at the end of the lease term at fair market value. The leases have terms ranging from three to five years. At December 31, 1998, no amounts were available under such agreements. The Company has entered into certain financing transactions and related capital equipment and facilities improvement master agreements for manufacturing equipment, general laboratory and scientific equipment, office equipment, furniture, fixtures and facilities improvements. At December 31, 1998, no amounts were available under such agreements. In connection with the August 1998 sale of a majority interest in its subsidiary, Proligo, (see Note 5-- Investment in Unconsolidated Affiliate), the Company transferred certain property and equipment with a net book value of $4.5 million to Proligo. The majority of such property and equipment is financed or leased by the Company in accordance with the aforementioned sale-leaseback transactions and financing arrangements. As part of this transaction, the Company transferred the underlying debt to Proligo pursuant to various Sublease, Consent and Assignment Agreements (collectively referred to as the "Sublease Agreements"). As a result, the Company is required to pay the debt financing and lease liabilities to the financial institutions directly for Proligo's share of the liabilities and Proligo is required to reimburse the Company for these amounts and is bound by the same terms and conditions as the Company's agreements with financial institutions and lessors. In the event that Proligo were to default on its obligations under the Sublease Agreements, the Company would continue to be liable for amounts outstanding as of the date of the default. At December 31, 1998, Proligo was current with respect to its reimbursements to the Company and the balance of Proligo's lease and debt liabilities under the Sublease Agreements was $2.8 million. Such liabilities are not included in the Company's Consolidated Balance Sheets. Additionally, the Company and Proligo entered into Assignment, Assumption and Consent Agreements (the "Agreements") with the landlords of two laboratory facilities Proligo occupies. Under the Agreements, Proligo has assumed the obligations to the landlords, but the Company remains liable in the event of default. The total unpaid amount of such operating lease commitments as of December 31, 1998 was approximately $560,000. F-14 NEXSTAR PHARMACEUTICALS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 11. COMMITMENTS AND CONTINGENCIES (CONTINUED) In the event Proligo defaults on any payments under the Sublease Agreements and the Company is required to cure such default on behalf of Proligo, SKW is obligated to reimburse the Company 51% of any amounts paid by the Company. Rent expense for the years ended December 31, 1998, 1997 and 1996 was approximately $4,618,000, $4,538,000 and $3,485,000, respectively.

("PLS"), a Canadian corporation incorporated in British Columbia. In June 1996, the Company's holdings in connection with PLS were restructured. Pursuant to the restructuring, the Company gave up its right to convert a Canadian $4,500,000 loan (the "Loan") (approximately $3,285,000 at the time of conversion and approximately $3,348,000 at December 31, 1995), which it made to PLS, into a 49.9% interest in PLS; converted Canadian $968,784 (approximately $707,000 at the time of conversion) of the Loan into 235,714 preference shares in PLS; and converted the Loan to a United States Dollar-based loan. In addition, PLS issued a warrant to the Company to acquire up to 300,000 PLS common shares for $3 per share and repaid the Company approximately $700,000 in connection with the Loan. During 1997, PLS repaid the Company $753,000 in connection with the Loan. The face amount of the Loan at December 31, 1997 was $1,737,000 with an outstanding allowance for loan loss of $1,737,000. In March 1998, the company received $550,000 as full settlement of the loan. SHORT-TERM BORROWINGS In March 1997, the Company entered into an agreement with a domestic bank pursuant to which the Company and certain of its subsidiaries could borrow up to $15 million, with the borrowings being collateralized by certain of the non-U.S. accounts receivable of the Company and its subsidiaries. In September 1997, the Company simultaneously terminated this agreement and entered into an unsecured line of credit with the same bank for $10 million (the "Credit Agreement"). Under the terms of the Credit Agreement, the Company is required to maintain certain financial ratios and there are limitations on the F-15 NEXSTAR PHARMACEUTICALS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 11. COMMITMENTS AND CONTINGENCIES (CONTINUED) Company's ability to incur additional debt or to engage in certain significant transactions. The Credit Agreement, which includes a foreign exchange facility, expires November 1, 1999. The short-term borrowings outstanding under the Credit Agreement at December 31, 1997 were $1,750,000. There were no amounts outstanding under this agreement as of December 31, 1998. In May 1996, the Company's Spanish subsidiary entered into an agreement to borrow up to 500 million Spanish Pesetas (approximately $3.3 million on December 31, 1997) with such borrowing being secured by the subsidiary's accounts receivable in Spain. In February 1997, the agreement was amended to increase the amount that the subsidiary may borrow to 750 million Spanish Pesetas (approximately $4.9 million on December 31, 1997). In connection with the agreement, the Company had to maintain $2.0 million in an unrestricted account. As of December 31, 1997, the subsidiary had borrowings of 500 million Spanish Pesetas (approximately $3.3 million on December 31, 1997) under the agreement. On April 1, 1998, the Company's Spanish subsidiary terminated the loan as to new borrowings and the balance of the loan was paid in full in September 1998. Additionally, the $2.0 million in the unrestricted acccount was returned to the Company. The weighted average interest rate on short-term borrowings as of December 31, 1997 was 6.89%. LICENSES AND ROYALTIES The Company has entered into license agreements with various commercial, medical and educational institutions to obtain certain exclusive and nonexclusive patent rights for the purpose of developing, manufacturing and selling potential products using these patented technologies. Under these agreements, the Company will pay royalties at varying rates based upon levels of revenues from the licensed products, as defined. Generally, the agreements continue as long as any licensed patents remain in force. In September 1996, the Company and Sumitomo Pharmaceuticals Co., Ltd. ("Sumitomo") entered into an agreement (the "Sumitomo License") pursuant to which Sumitomo will develop and market AmBisome in Japan. Under the terms of the Sumitomo License, Sumitomo paid the Company an initial $7 million licensing fee (less withholding taxes of $700,000) in October 1996 and a $3,000,000 milestone payment (less withholding taxes of $300,000) in March 1998. Sumitomo also is required to make additional payments to the Company if certain clinical and commercial milestones are met and to pay the Company royalties on all Japanese AmBisome sales. The Company's rights to market AmBisome are subject to an agreement between the Company and Fujisawa Healthcare, Inc., as successor to Fujisawa USA, Inc. ("Fujisawa"). Under the terms of the agreement, as amended, Fujisawa and the Company co-promote AmBisome in the United States, Fujisawa has sole marketing rights to AmBisome in Canada and the Company has exclusive marketing rights to AmBisome in the rest of the world, provided the Company is required to pay royalties to Fujisawa in connection with sales in most significant Asian markets, including Japan. In connection with U.S. sales, Fujisawa purchases AmBisome from the Company at cost; Fujisawa collects all payments from the sale of AmBisome in the U.S., and the Company receives 20% of the gross profits from the sale of AmBisome in the United States. In 1998 and 1997, the Company recorded $4.8 million and $671,000 of royalty income, respectively, in connection with the agreement between the Company and Fujisawa. F-16 NEXSTAR PHARMACEUTICALS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 11. COMMITMENTS AND CONTINGENCIES (CONTINUED) PATENT MATTERS On August 11, 1997, the Company and The Liposome Company, Inc. ("TLC") reached a settlement in which the two companies agreed to dismiss all legal proceedings involving TLC's reexamined U.S. Patent No. 4,880,635 (the "TLC '635 Patent") and U.S. Patent No. 5,578,320 (the "TLC '320 Patent") and their international counterparts. The legal proceedings related to whether AmBisome, the Company's liposomal formulation of amphotericin B, infringed TLC's patents because of the manner in which it is freeze dried (lyophilized). In the settlement agreement between the parties, TLC granted the Company immunity from suit in connection with the worldwide production and sales of AmBisome and a worldwide right to use the TLC '635 Patent and the TLC '320 Patent. Under the terms of the Settlement Agreement, the Company made an initial payment to TLC of $1.75 million and is required to make payments which began in 1998 based on AmBisome sales over the next several years. Because the payments are subject to certain minimum and maximum amounts, the Company recorded accounting charges in 1997 of $11.8 million, of which $10.0 million represented the net present value of all future minimum payments it is required to make and $1.75 million represented the initial cash payment. Beginning in 1998, the Company is recording an expense each quarter related to the difference between all future minimum payments and the expense recorded in 1997. In addition, beginning in 1998, the Company is expensing the difference between the minimum and maximum payments, if any. The Company does not expect the difference between its future minimum and maximum payments to TLC to be material. LEGAL PROCEEDINGS GENERALLY The Company is involved, from time to time, in legal proceedings arising in the ordinary course of its business. In the opinion of management, after consultation with legal counsel, none of these matters, based on factors currently known to management, is expected to have a material adverse effect on the financial position of the Company. NOTE 12. STOCKHOLDERS' EQUITY COMMON STOCK On May 27, 1998, the Company entered into a three-part collaboration with Glaxo Wellcome in which (a) Glaxo Wellcome received a non-exclusive right to practice the Company's proprietary SELEX process for target validation; (b) the Company received the exclusive rights to develop and commercialize a liposomal formulation of Glaxo Wellcome's proprietary topoisomerase I inhibitor (lurtotecan); and (c) Glaxo Wellcome acquired 962,117 shares of the Company's common stock, $.01 par value (the "Shares") for $10 million. The Shares were sold in a private offering in reliance on Section 4(2) of the Securities Act of 1933, as amended, since Glaxo Wellcome is a sophisticated investor. In connection with the sale of the Shares, Glaxo Wellcome was granted certain registration rights. On February 13, 1996, the Company completed a private sale of 1,425,000 shares of its common stock to a group of private investors (the "Private Investors"). The net proceeds to the Company from the sale were approximately $24.9 million. In connection with the transaction, the Company filed a "shelf" registration statement on Form S-3 registering for resale the shares acquired by the Private Investors. Pursuant to its agreement with the Private Investors, the Company is required to keep the "resale" registration statement effective for up to three years. As of March 18, 1999 such registration statement remains effective. In addition to the Private Investors, a holder of 297,619 shares of the Company's common stock and two holders of warrants to acquire 250,481 shares of the Company's common stock F-17 NEXSTAR PHARMACEUTICALS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 12. STOCKHOLDERS' EQUITY (CONTINUED) exercised registration rights granted to them by the Company and had their shares of common stock, or the shares of common stock which relate to their warrants, included in the registration statement. WARRANTS Outstanding common stock warrants are summarized as follows: RANGE OF EXERCISE SHARES EXPIRATION WARRANTS PRICES RESERVED DATES --------- -------------- --------- ------------ Outstanding, December 31, 1997 and 1998............. 256,285 $ 4.09-$32.54 256,285 1999-2003 In 1990, the Company issued to Warburg, Pincus Capital Partners, L.P. ("WPCP"), which at that time was a beneficial owner of more than 5% of the Company's common stock, a warrant to purchase 1,035,294 shares of the Company's common stock at an exercise price of $4.83 per share, which was issued in connection with the sale of certain equity securities of the Company. In April 1995, WPCP's warrant was amended to change the expiration date to December 31, 1997. On September 30, 1997, WPCP exercised its warrant for 1,035,294 shares in a net exercise and received 753,577 shares of the Company's common stock. In March 1997, Warburg, Pincus Investors, L.P. ("WPI"), which is an owner of more than 5% of the Company's common stock, received a warrant to acquire 125,000 shares of the Company's common stock at a purchase price of $12.50 per share in return for an affiliate of WPI guaranteeing a credit line entered into by the Company (the "Credit Line"). Under the Credit Line, which was terminated in July 1997, the Company was permitted to borrow up to $15 million. REGISTRATION RIGHTS Under certain circumstances, the Company's common stockholders and holders of warrants to purchase common stock of the Company may require a registration of the outstanding common shares or the shares underlying warrants, the cost of which would be borne by the Company. STOCK OPTIONS AND STOCK-BASED COMPENSATION On February 8, 1993, the Company adopted the 1993 Incentive Stock Plan (the "1993 Plan") for employees, directors, and consultants of NeXstar Pharmaceuticals, which provides for the sale of shares or the issuance of incentive and nonstatutory stock options for common stock. Options issued under the 1993 Plan are exercisable under conditions as determined by the Board of Directors, with the term of each option being a maximum of ten years from the date of grant. On May 28, 1997, the number of shares that can be granted under the 1993 Plan was increased by 1,500,000 shares to 3,904,847 shares. The Company has reserved 3,904,847 shares of its authorized common stock under the 1993 Plan. Options granted prior to November 1993 vested 20% immediately and 20% on the grant date anniversary each year thereafter for four years. Options granted after October 1993 generally vest 25% on each anniversary date of the four years following the grant date. The Company has reserved for issuance 1,204,904 shares of its common stock to allow for the exercise of options under its 1988 Stock Option Plan (the "1988 Plan"). Options granted under the 1988 Plan are exercisable upon conditions determined by the Board of Directors of the Company, and expire no later than ten years from the date of grant. No additional options may be issued under the 1988 Plan. F-18 NEXSTAR PHARMACEUTICALS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 12. STOCKHOLDERS' EQUITY (CONTINUED) On July 25, 1995, the Company adopted the 1995 Director Option Plan (the "Director Plan"). Under the Director Plan, each outside director of the Company is entitled to receive an option for 10,000 shares of the Company's common stock on the date on which such person first becomes an outside director. In addition, each outside director who has served on the Board of Directors for at least six months automatically is entitled to receive an option grant for 5,000 shares on the last business day prior to each annual meeting of stockholders of the Company. The options have a term of ten years, an exercise price equal to 100% of the fair market value of the common stock on the date of grant and vest 50% on each anniversary date of the two years following the grant date. Options for up to 500,000 shares of common stock may be issued under the Director Plan. In 1998, options for 20,000 shares were issued to four outside directors. In 1997, options for 40,000 shares were issued to six outside directors. In 1996, options for 15,000 shares were issued to three outside directors.

The Company has elected to follow Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB No. 25"), in accounting for its employee stock options because, as discussed below, the alternative fair value accounting provided for under FASB Statement No. 123, "Accounting for Stock-Based Compensation" ("Statement No. 123"), requires use of option valuation models that were not developed for use in valuing employee stock options. Because the exercise price of the Company's employee stock options equals the market price of the underlying stock on the date of grant, no compensation expense is recognized under APB No. 25. Statement No. 123 requires disclosure of pro forma net income and pro forma earnings per share. It also requires that the pro forma information be determined as if the Company has accounted for its employee stock options granted subsequent to December 31, 1994 under the fair value method of Statement No. 123. The fair value for these options was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted-average assumptions for 1998, 1997 and 1996, respectively: risk-free interest rates of 4.73%, 5.59% and 5.49%; a dividend yield of 0%; volatility factors of the expected market price of the Company's common stock of .6144, .5178 and .7240; and an average expected life of the options after vesting date of 1.44, 1.00 and 1.23 years. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options, which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions, including the expected stock price volatility. Because the Company's employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management's opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options. F-20 NEXSTAR PHARMACEUTICALS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 12. STOCKHOLDERS' EQUITY (CONTINUED) For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the options' vesting periods. The Company's pro forma information is as follows: YEARS ENDED DECEMBER 31, -------------------------------------------- 1998 1997 1996 ------------ -------------- -------------- Pro forma net income (loss).............................. $ 6,815,000 $ (47,900,000) $ (26,080,000) Pro forma net income (loss) per basic and diluted share.................................................. $ 0.24 $ (1.79) $ (1.00) Because Statement No. 123 is applicable only to options granted subsequent to December 15, 1994, its pro forma effect was not fully reflected until the fiscal year ended December 31, 1998. As a result of nonstatutory stock options granted to consultants in 1997 and 1996, the Company recorded deferred compensation of $44,000 and $301,000, respectively, which is being amortized over a period of four years. The Company recognized $83,000, $142,000 and $51,000 as a non-cash charge to earnings during 1998, 1997 and 1996, respectively, as a result of this amortization. As a result of compensatory stock issuances and option grants in 1993, the Company recorded deferred compensation of $470,000 that it amortized over a period of four years. RESTRICTIONS ON PAYMENT OF DIVIDENDS Certain of the Company's bank and building improvement and equipment lease facilities require the Company to maintain certain financial ratios and levels of cash and/or stockholders' equity which may have the effect of limiting the Company's ability to pay dividends. NOTE 13. EMPLOYEE BENEFIT PLANS EMPLOYEE STOCK PURCHASE PLAN On June 9, 1994, the Company adopted an employee stock purchase plan (the "Stock Purchase Plan") with an effective date of August 1, 1994, under Internal Revenue Code Section 423, which provides for the sale to employees of up to 500,000 shares of common stock. The Company has reserved 500,000 shares of its authorized common stock in connection with the Stock Purchase Plan. Employees who work at least twenty hours per week and at least five months per calendar year may participate. The granting of rights (options) to purchase common stock of the Company is determined by the Board of Directors. As of December 31, 1998, a total of 281,469 shares have been purchased at prices per share from $4.78 to $15.30, which represented 85% of the fair market value of the common stock on the lower of the offering date or the date of exercise.

Employee contributions are discretionary, but are not to exceed 15% of eligible annual compensation. The Savings Plan includes a Company match of 50% of employee contributions up to a maximum of 6% of eligible annual compensation. For the years ended December 31, 1998, 1997, and 1996, the Company recorded expenses related to the Savings Plan of approximately $506,000, $580,000 and $513,000, respectively. At December 31, 1998, approximately $720,000, representing 77,296 shares of the Company's common stock, was held by the Savings Plan in trust for plan participants. Additional contributions of Company stock are not allowed under the Savings Plan. NOTE 14. EMPLOYEE RELATED EXPENSES AND OTHER CHARGES In August 1998, the Company entered into a separation agreement with Patrick J. Mahaffy upon his resignation as President, Chief Executive Officer and Director of the Company and recorded a selling, general and administrative expense of $760,000. In August 1998, the Company announced its intentions to evaluate the possible spin off of its drug discovery business into a separate publicly traded company to be known as Iterex Technologies, Inc. ("Iterex"). In 1998, the Company incurred $664,000 of selling, general and administrative expenses related to the potential Iterex spin-off. On February 28, 1999, the Company announced a Merger Agreement with Gilead. Pending the completion of the Merger, the Iterex spin-off will not occur and the Company's drug discovery business will remain part of the Company. In 1999, the Company expects to record selling, general and administrative expenses of approximately $400,000 related to Iterex spin-off costs incurred prior to the announcement of the Merger.
