PART I ITEM 1. BUSINESS In addition to historical information, this report contains predictions, estimates and other forward-looking statements that involve a number of risks and uncertainties that are described more fully in "Item 1 - Risk Factors." While this outlook represents our current judgment on the future direction of the business, these risks and uncertainties are only some of the factors that may ultimately affect the success of Shaman Pharmaceuticals, Inc. Actual results may differ materially from any future performance suggested in this report. The Company Shaman is a leader in the identification and development of novel pharmaceutical products for the treatment of human diseases through the isolation and optimization of active compounds found in tropical plants. The Company believes that by focusing on drugs extracted from plants with a long history of medicinal use, its drug discovery efforts will be quicker and more likely to lead to safe and effective pharmaceuticals. Shaman has human clinical trials underway for its three lead product candidates: Provir, nikkomycin Z, and SP-134101. Shaman has completed Phase II trials showing efficacy for Provir for the treatment of AIDS-associated and watery diarrhea. In the first quarter of 1998, Provir is scheduled to enter a pivotal Phase III trial for the treatment of diarrhea in patients with AIDS. This single study, upon completion, is intended to serve as the basis for the submission of a New Drug Application ("NDA") with the U.S. Food and Drug Administration ("FDA"). With success, Provir for diarrhea in patients with AIDS will become the first product commercialized by Shaman. Two additional dose-optimizing Phase II trials for Provir in watery diarrhea commenced in 1997. These trials are intended to be completed in the first half of 1998 and, if successful, will lead to Phase III trials. Nikkomycin Z, an orally-active product for the treatment of endemic mycoses and other systemic fungal infections, completed a Phase I trial in the UK in 1997, and the Company filed an Investigational New Drug application ("IND") in the United States in December 1997. The Company intends to continue multi-dose Phase I testing of this compound. Shaman's research and preclinical development is principally focused on the identification and optimization of compounds to treat Type II (adult onset or non-insulin dependent) diabetes, an effort that has led to the identification of 21 chemically distinct, orally-active compounds which have demonstrated glucose lowering effects in preclinical animal testing. In October 1997, Shaman filed an IND for SP-134101, an oral product for the treatment of Type II diabetes. This first product to emerge from the diabetes discovery program entered clinical trials in January 1998. Significant funding, as well as milestone payments for this program, are provided through collaborations with Lipha, s.a., a wholly-owned subsidiary of Merck KGaA, Darmstadt, Germany ("Lipha/Merck"), and Ono Pharmaceutical Co., Ltd. ("Ono"). Background Shaman builds on the knowledge and expertise of ethnobotanist and physician teams who work with traditional healers to identify effective treatments for the therapeutic areas targeted by the Company. These teams gather comparative data on traditional medicinal uses of plants from geographically diverse tropical areas and prioritize plant drug candidates based on common use among cultures and other factors, including cross-checking field-derived information against the results of literature searches as to chemical constituents, previously discovered biological activity and other reported medicinal uses. Shaman isolates and identifies the active compounds from plant extracts by testing for activity in whole animal models at each step of its purification process. The Company's 2 natural product chemists use chromatography, spectroscopy, nuclear magnetic resonance ("NMR") and other proven technologies to identify and isolate compounds and structures. Because these compounds reflect the previously untapped plant diversity of the rain forests, they have, to date, also exhibited significant diversity of chemical structure. In addition, the Company's whole animal screening approach provides the opportunity to discover novel methods of treatment for diseases in which the underlying mechanism of action of a disease is complicated and not well understood. The Shaman Strategy Shaman's strategy is to employ a drug discovery process focused on diseases that: o appear to result from multiple and, in many cases, unknown causes and therefore may not be amenable to a targeted in vitro drug discovery process; o occur in the rain forests and are readily recognized and treated by traditional healers (e.g., foot ulcers, sweet urine, poor eyesight and fungal infections are often predictive of Type II diabetes); and o allow the plant extract treatment to be confirmed in a whole animal model and then purified to isolate the active compound. Shaman believes this drug discovery process provides it with the opportunity to: o identify novel methods of treating diseases with therapeutic relevance; o discover new chemical entities or new classes of compounds to treat disease; and o provide early confirmation of efficacy and safety. Shaman intends to commercialize its products through licensing arrangements when safety and efficacy have been demonstrated in humans. Shaman intends to out-license broad applications of its products worldwide while retaining the opportunity to directly access markets through niche applications and/or co-promotion. 3 Clinical and Research Programs Shaman has established and is continuing to build a portfolio of product candidates. The following table describes the major therapeutic areas in which the Company is conducting its product development and research: Product Indication Status Commercial Rights - ------- ---------- ------ ----------------- Provir AIDS-associated Entering Phase III Shaman diarrhea pivotal study- Q1, 1998. Completed a Phase II efficacy study in Q4, 1997 Provir Watery diarrhea Commenced two Phase II Shaman dosing trials in Q3 & Q4, 1997.

Shaman compounds receives royalties on sales outside the U.S. and profit sharing in the U.S. Provir The Shaman-patented compound SP-303 is the active ingredient in Provir. SP-303 is extracted from the latex of the Croton tree, which grows abundantly in Latin America. This latex is used orally by many native cultures throughout Latin America for a variety of medicinal purposes, including respiratory infections and gastrointestinal problems. Provir is an oral drug that acts as a specific inhibitor of fluid loss via an antisecretory mechanism to treat diarrhea. In clinical trials, the Company determined that Provir is not systemically absorbed, which lessens the potential for drug interactions and side effects. Provir has demonstrated initial indications of activity for diarrhea in patients with AIDS. Based upon successful Phase II study results released in October 1997 in AIDS patients with diarrhea, Provir is scheduled to enter a Phase III trial in this population during the first quarter of 1998. If successful, this single study will serve as the basis for an NDA submission that the Company is currently targeting for 1999. Shaman has also completed Phase II trials showing preliminary efficacy for Provir for the treatment of watery diarrhea. However, in October 1997, interim results from one outpatient study in mild non-specific diarrhea did not show significant efficacy and the trial was discontinued. To further determine Provir's effect in other more severe diarrheas, two additional dose-optimization Phase II trials in moderate-to-severe traveler's and inpatient acute watery diarrhea are currently underway. Diarrhea in Patients with AIDS/HIV Diarrhea in patients with HIV and AIDS is a devastating syndrome which afflicts between 20% and 60% of patients. Even given the success of protease inhibitors and triple anti-HIV regimens in 4 improving patient prognosis, the problem of diarrhea continues and has emerged as a major medical and quality of life problem as patients attempt to live a normal lifestyle. Unfortunately, current symptomatic therapies provide either poor relief or bring with them the burden of unacceptable side effects. Hence, this population faces a serious unmet medical need. In the face of these problems, patients with chronic diarrhea have been forced to alter their lifestyle to accommodate this disruption in the activities of daily life. Provir is currently being developed for the treatment of diarrhea in patients with AIDS. A recently completed (October 1997) Phase II study enrolled AIDS patients with chronic diarrhea. Patients were randomized to receive either SP-303 500 mg or placebo given every six hours (q6h) for four days. Fifty-one patients (26 received SP-303, 25 received placebo) were available to evaluate drug efficacy. There were no significant differences between the treatment arms with respect to any of the baseline demographic variables examined. Of the 51 fully evaluable patients, 48 (94.1%) had no identifiable pathogen isolated from their screening stool sample (culture and microscopic examination). Treatment with SP-303 was well tolerated with no imbalance between groups in the occurrence of adverse events or in treatment-emergent laboratory abnormalities, and all were considered mild in nature. At day four, the SP-303 treated group demonstrated a mean reduction from baseline stool weight of 451.3 grams per 24 hours as compared to 150.7 grams per 24 hours in the patients receiving placebo. In addition, abnormal stool frequency decreased from a mean of 5.2 per 24 hours at baseline to 2.2 per 24 hours in the Provir-treated group, compared to 3.1 in the placebo group. A longitudinal random regression analysis of the treatment effect over four days indicated the patients treated with SP-303 experienced a statistically significant reduction in stool weight (p=0.008) and in abnormal stool frequency (p=0.039) when compared with placebo. The point-in-time analysis comparing baseline to Day 4 of treatment yielded p-values of p=0.14 in mean reduction in stool weight, and p=0.26 in mean reduction in abnormal stool frequency. The mean maximal time between abnormal stools was greater in the SP-303 group (30.6 hours) as compared with patients who received placebo (24.6 hours, p = 0.035). The results of this study suggest that SP-303 is effective in reducing stool weight and abnormal stool frequency in patients with AIDS and chronic or sub-acute diarrhea. A Phase III trial designed to confirm the Phase II results is planned to begin in the first quarter of 1998. During the Phase III clinical trial, Provir will be studied in a larger number of patients for a longer duration of therapy, including outpatient experience. Agreement has been reached with the U.S. FDA on the trial design, including endpoints, for this pivotal Phase III study, which, if successful, may enable the company to file an NDA for this indication in 1999. Based on these Phase II results and the Phase III plan, Shaman is actively pursuing a commercialization partnership with other AIDS-focused companies for this indication. Watery Diarrhea Watery diarrhea is often caused by infectious agents such as V. cholerae and E. coli. These agents secrete toxins that adhere to the intestinal wall and cause increased secretion of chloride ions from intestinal cells, resulting in fluid accumulation in the small intestine. This in turn leads to severe and, in some cases, life threatening diarrhea. According to the 1995 data from the IMS America, Ltd. ("IMS"), the leading pharmaceutical marketing data firm, over 26 million prescriptions are written annually for watery diarrhea. Moreover, approximately 67 million over-the-counter product units are sold in the U.S. alone. Current primary treatments for watery diarrhea do not address the dehydration or fluid loss caused by the illness. Watery diarrhea is typically treated with one of two treatment regimens: 5 antibiotics or antimotility agents. Antibiotics kill the bacteria, while antimotility agents reduce diarrhea frequency by inhibiting peristaltic action (natural muscular contraction of the intestinal tract). For mild to moderate cases of watery diarrhea, the use of antibiotics is discouraged by the World Health Organization ("WHO") and the Centers for Disease Control ("CDC"). Bacteria can, in many cases, build up a resistance to antibiotics and antibiotics can reduce the body's ability to build natural immunities to disease and, therefore, increase the likelihood of reinfection. While antimotility agents are effective in reducing the severity of watery diarrhea, they often cause severe constipation. In addition, because of reduced motility in the intestine, the bacteria are often not eliminated and remain in the gut. When the treatment is stopped, the patient often experiences rebound diarrhea. Moreover, these agents are not recommended in children and the elderly because of the risk of prolonging the illness. Preclinical studies indicate that Provir treats watery diarrhea by inhibiting the secretion of chloride ions from intestinal cells, specifically countering fluid loss, a fundamental mechanism causing diarrhea. Based on its mechanism of action and results of initial clinical testing, it appears that Provir does not affect the normal motility of the intestine and the lack of absorption of Provir in the intestine contributes to its safety, its reduced potential for drug interactions, and its specificity of action. Shaman has conducted Phase I clinical trials for Provir in more than 150 adults, children and infants as young as three months of age, in both single and multiple doses. These trials demonstrated that Provir is safe and can be easily tolerated in doses up to two grams per day for two days. The results also indicated no significant adverse side effects of the drug. In November 1996, the Company completed a Phase II trial in 75 patients to determine the efficacy of Provir in the treatment of traveler's and non-specific diarrhea. This open-label Phase II study was conducted by Dr. Herbert DuPont, a world recognized expert in travel medicine, of the University of Texas at Houston and Baylor College of Medicine. It included American subjects who suffered from diarrhea upon traveling to Mexico as well as native Mexicans suffering from diarrhea of unknown cause, or non-specific diarrhea. In the Phase II study, 89% of the 75 patients treated with Provir responded favorably (returned to normal bowel function) after 48 hours of treatment, with over 60% of those patients returning to normal after just 24 hours. Traveler's diarrhea left untreated usually lasts five to seven days. Non-specific diarrhea usually lasts three to four days. Of the 71 patients available for follow up, none of the patients experienced worsening of the diarrhea illness once resolution of the disease began. In addition, no significant adverse reactions were reported. Of 25 patients with traveler's diarrhea receiving one or two grams of Provir per day, effectiveness (measured as a combination of stool frequency, stool consistency, and gastrointestinal symptoms) was demonstrated in 72% of patients over the course of the study. Within this patient group, the mean time to last unformed stool, the most significant indicator of therapeutic effect, was 58% less than historical controls would indicate. The patients experiencing non-specific diarrhea of unknown etiology received either a one or two gram dose per day for two days. In the group of 15 patients receiving the one gram dose, all patients responded to therapy, and 87% returned to normal stool frequency after 24 hours of treatment. In the group of 35 patients receiving the two gram dose, 34 patients responded to therapy, and 80% returned to normal stool frequency after 24 hours of treatment. The mean time to last unformed stool was reduced by 50% in the one gram dose group and 32 percent in the two gram dose group compared to the historical control in a cure study. In October 1997, the Company determined from an interim analysis of another Phase II outpatient study of 166 Mexican nationals with mild non-specific diarrhea that Provir provided no benefit over placebo after two days of treatment. In this mild, non-specific diarrhea, it was difficult to show an 6 added benefit of Provir therapy during the short course of illness. Based on these results, the Company suspended its study of mild, non-specific diarrhea and is now focusing on moderate-to-severe diarrhea. In the Third and Fourth quarters of 1997, Shaman initiated two double-blind, randomized, placebo controlled Phase II studies of Provir designed to determine the optimal effective dose level of Provir for the treatment of moderate-to-severe watery diarrhea. These studies include an outpatient study of travelers in Mexico and Jamaica, as well as an in-hospital study in Venezuela. Pediatric Diarrhea According to the Journal of Pediatrics, in the United States alone, over 30 million episodes of diarrhea occur annually in children under five years of age. In addition, there are over one billion episodes of pediatric diarrhea worldwide annually and four million deaths associated with pediatric diarrhea per year among children less than five years old in developing countries. Current recommended therapies for pediatric diarrhea are designed to replace water and electrolytes. Antimotility agents are contraindicated in children less than two years of age and not recommended for treatment of diarrhea in children of any age. In the vast majority of diarrheal illnesses in the United States, particularly those in children, the use of antibiotics is not recommended. Shaman is currently engaged in formulation development of Provir as a potential treatment for pediatric diarrhea in preparation for initiating a clinical development program. Nikkomycin Z Nikkomycin Z was licensed in 1995 from Bayer AG. See "Business--Collaborative Relationships and License Agreements." Nikkomycin Z is an orally administered product designed for the treatment of endemic mycoses and other systemic fungal infections. Nikkomycin Z is novel in its mechanism of action against fungal infections. Preclinical studies of nikkomycin Z indicate that it is fungicidal and could prove superior to current treatments. By inhibiting chitin synthetase, which is found in the cell walls of most fungi, but not in mammalian cells, nikkomycin Z inhibits cell wall synthesis, ultimately causing fungal cells to expand and burst. The lack of chitin in mammalian cells should prevent similar damage to normal cells in tissues affected by these fungal infections. Endemic mycoses are systemic fungal infections concentrated in the southwest, central and northeast regions of the United States. There are three basic forms of endemic mycoses: coccidiomycosis (valley fever), histoplasmosis and blastomycosis ("cocci," "histo" and "blasto"). The infecting organisms are found in soil. When the soil is disturbed (such as during crop planting or harvesting), the fungi become airborne and may be inhaled into the lungs. Once infected, otherwise healthy individuals will experience mild flu-like symptoms but may never be diagnosed with the disease. In more severe cases, however, the fungus spreads systemically and results in disseminated fungal infections. It is estimated that approximately 240,000 persons per year in the United States show clinical symptoms of endemic mycoses. The Company believes that the annual market for treatment of endemic mycoses in the United States is approximately $150 million. Currently, two classes of drugs are commonly prescribed of the treatment for endemic mycoses: azoles, which are fungistatic (inhibit the growth of the fungus, but do not kill it) and polyenes (including amphotericin B), which are fungicidal (kill the fungus). However, often these drugs cannot be tolerated in high enough doses to kill the fungi. Nikkomycin Z is an orally active product for the treatment of endemic mycoses and other systemic fungal infections. A single-dose Phase I trial in the UK was completed in 1997. Shaman filed an IND in the United States to test nikkomycin Z in December 1997 and intends to begin multi-dose Phase I testing in 1998. 7 Candidiasis is a fungal infection that can result in serious systemic disease. Approximately 265,000 patients worldwide are treated annually for systemic candidiasis. Nikkomycin Z has also been shown to be capable of interacting in a synergistic fashion with a number of known antifungal compounds, including fluconazole (Diflucan) and itraconazole (Sporonox), the two largest selling antifungals in the world. Based on this synergistic activity, the Company plans to supply nikkomycin Z to Pfizer Corporation for a combination study that tests nikkomycin Z in combination with fluconazole in treating azole-resistant esophageal candidiasis. The estimated annual total market of antifungal agent sales for systemic fungal infections is approximately $2.0 billion. Virend Shaman recently suspended a Phase II clinical trial of Virend, a topical treatment for herpes, which was being studied in combination with oral acyclovir in patients with AIDS. It was determined from an interim analysis that there were no additional benefits to the use of Virend over the use of oral acyclovir alone. Based on these results, the Company has suspended this program. SP-134101 SP-134101 is a Shaman-patented, oral product for the treatment of Type II diabetes. In October 1997, Shaman filed the IND for SP-134101, the first product to emerge from the diabetes discovery effort. A Phase I trial for the compound began in January 1998. In preclinical studies SP-134101 has been shown to lower blood glucose, triglycerides, and blood pressure. SP-134101 appears to work by increasing glucose uptake in the peripheral tissues and decreasing triglyceride output from the liver. Drug Discovery Research Diabetes Type II diabetes is a chronic disease in which the tissues of the body are resistant to the actions of insulin (a hormone produced by the pancreas), and the pancreas cannot secrete enough insulin to overcome this resistance. When this happens, the ability of insulin to carry out its normal action on the liver, muscle and adipose tissues is lost, the result is increased blood glucose and associated symptoms. This disease is the result of multiple causes, many of which are undefined at the molecular level. In the United States alone, approximately 625,000 new cases of Type II diabetes are diagnosed each year, and it is estimated that there will be over 18 million cases by the year 2002 (over five percent of the population). Shaman is focused on the development of oral antihyperglycemic (blood glucose lowering) agents for the treatment of Type II diabetes. The program involves in vivo screening of plants by oral administration in animal models, followed by the fractionation of active extracts, the isolation and identification of active compounds, and the capability to profile and prioritize promising candidates for clinical development. In just over 24 months of this program, the Company has identified 21 orally-active compounds for which, to date, 14 original U.S. patent applications have been filed (five of which have been issued) and eleven international patent applications have been filed. These compounds represent new classes and, potentially, new methods for treating Type II diabetes. The diabetes research and development program serves as the basis for Shaman's collaboration with Lipha/Merck and Ono. Significant funding, as well as milestone payments for this program, result from these collaborations. See "Business--Collaborative Relationships and License Agreements." 8 The Company filed an IND for its first diabetes compound, SP-134101, in 1997, and began a Phase I trial for the compound in January 1998. Collaborative Relationships and License Agreements In September 1996, the Company entered into a five-year collaborative agreement with Lipha/Merck to develop jointly Shaman's antihyperglycemic drugs. In exchange for development and marketing rights in all countries except Japan, South Korea and Taiwan (which are covered under an earlier agreement between Shaman and Ono), Lipha/Merck will provide up to $9.0 million in research payments and up to $10.5 million in equity investments priced at a 20% premium to a multi-day volume weighted average price of the Company's Common Stock at the time of purchase. Of the $4.5 million received on signing the agreement, $1.5 million was an up-front research payment and $3.0 million was an equity investment. The agreement also provides for additional preclinical and clinical milestone payments to the Company in excess of $10.0 million per compound for each antihyperglycemic drug developed and commercialized. To date, Shaman has identified 21 proprietary, orally-active compounds which show preclinical activity as treatments for Type II diabetes. Lipha/Merck will bear all pre-clinical, clinical, regulatory and other development expenses associated with the compounds selected under the agreement. In addition, as products are commercialized, Shaman will receive royalties on all product sales outside the United States and up to 50% of the profits (if the Company exercises its co-promotion rights) or royalties on all product sales in the United States. Certain of the milestone payments will be credited against future royalty payments, if any, due to the Company from sales of products developed pursuant to the agreement. In May 1995, the Company entered into a collaborative agreement with Ono providing for, among other things, three years of funding for the research and development of compounds for the treatment of Type II diabetes. Under the terms of the agreement, Shaman will screen 100 diabetes-specific plants per year in vivo, isolate and identify active compounds, and participate in any medicinal chemistry modification. In turn, Ono will provide Shaman with access to Ono's preclinical and clinical development capabilities through proprietary in vitro assays and medicinal chemistry efforts. Ono's development and commercialization rights are for the countries of Japan, South Korea and Taiwan. Under the terms of the Agreement, Ono will provide $7.0 million in collaborative research funding and will pay preclinical and clinical milestone payments of $4.0 million per compound for each antidiabetic drug that is commercialized. Of the $3.0 million received on signing the agreement, $1.0 million was an up-front research payment. Shaman received an additional $1.0 million payment (beyond the $7.0 million commitment) in December 1996 for enhanced access rights to these compounds. In June 1995, the Company licensed several patents from Bayer AG relating to the use of nikkomycin Z and the composition and use of nikkomycin Z in combination with other antifungal compounds for the development of antifungal agents. Under the terms of the agreement, the Company has paid Bayer AG an initial milestone payment and may be required, upon the occurrence of certain events, to make additional milestone payments and to pay royalties on any commercialized products derived from the agreement. In February 1990, the Company entered into a license agreement with Dr. Michael Tempesta. There currently exists a dispute with Dr. Tempesta over the scope and coverage, if any, of the license. The maximum royalty claimed by Dr. Tempesta is two percent on net sales of a certain antiviral agent. In November 1996, a demand for arbitration was filed by the Company to address a claim made by Dr. Tempesta that the royalty will be payable with respect to either or both of Provir and Virend. See "Legal Proceedings." 9 As the Company continues its product development and commercialization, it intends to enter into additional corporate alliances which may include licenses and/or marketing rights to selected products and markets. Manufacturing Shaman intends to conduct both pilot-scale and commercial manufacturing of its future products either in-house, with collaborative partners, or through contract manufacturing facilities. The Company has created an in-house facility that operates under Good Manufacturing Practices ("GMP") and has conducted pilot-scale manufacturing of SP-303. The Company has a sufficient quantity of raw material for SP-303 and SP-303 manufacturing capacity to complete currently planned clinical trials. In addition, Shaman also expects to establish a second source manufacturing facility to produce clinical and early commercial lots in 1998. In January 1996, the Company entered into an agreement with Abbott Laboratories ("Abbott") for the production of nikkomycin Z. Abbott has developed processes and manufactured nikkomycin Z in compliance with GMP guidelines for the Company's clinical trial programs. SP-134101 is being manufactured by a contract manufacturer in compliance with GMP guidelines for the Company's clinical trial programs. Marketing In July 1997, Shaman hired a senior executive to direct commercial development, including sales and marketing. The Company's general strategy is to develop corporate alliances with larger pharmaceutical companies for certain of its programs in order to take advantage of such companies' abilities to reach broad-based markets. Shaman is also evaluating the opportunity to retain certain marketing rights to its products. At the present time, Shaman has no sales staff. See "Business--Collaborative Relationships and License Agreements" and "Risk Factors--Limited Manufacturing and Marketing Experience and Capacity." Patents and Proprietary Technology Proprietary protection for the Company's product candidates, processes and know-how is important to the Company's business. The Company's policy is to file patent applications to protect technology, inventions and improvements that are considered commercially important to the development of its business. The Company also relies upon trade secrets, know-how and continuing technological innovation to develop and maintain its competitive position. The Company plans to aggressively prosecute and defend its patents and proprietary technology. The Company has been issued a U.S. patent related to its specific proanthocyanidin polymer compositions designated SP-303; specifically, the patent contains composition of matter claims related to SP-303 contained in the Company's Provir product. The Company has also filed foreign applications corresponding to its issued U.S. patents relating to its proanthocyanidin polymer composition. The Company has been granted patents in Australia, Mexico and New Zealand and has patent applications pending in Canada, Europe, Japan, the Republic of Korea and Singapore. The Company has also recently filed a U.S. patent application directed to new formulations and methods of using its specific proanthocyanidin polymer composition for treatment of watery diarrhea. These formulations are contained in the Company's Provir product. 10 The Company has five issued U.S. patents relating to compositions and methods for treating Type II diabetes, as well as reducing hyperglycemia associated with other etiologies. The Company also has nine additional U.S. patent applications still pending which relate to compositions and methods for treating Type II diabetes, as well as reducing hyperglycemia associated with other etiologies. The Company has filed eleven foreign applications, i.e., international applications under the Patent Cooperation Treaty designating a number of foreign countries, as well as applications in Taiwan, corresponding to a number of the U.S. applications and plans to file additional corresponding foreign applications within the relevant convention periods. The Company also has one pending U.S. patent application and a corresponding international patent application designating a number of foreign countries relating to methods for administering and sustained release formulations for anti-fungal agents like nikkomycin Z. The methods and compositions are useful for treatment of fungal infections, particularly candidiasis, the most frequently encountered life-threatening mycoses. The Company has licensed several patents from Bayer AG relating to the use of nikkomycin Z and the composition and use of nikkomycin Z in combination with other antifungal compounds for the development of antifungal agents. There can be no assurance that the Company's pending patent applications will result in patents being issued or that, if issued, patents will afford protection against competitors with similar technology; nor can there be any assurance that others will not obtain patents that the Company would need to license or circumvent. See "Risk Factors--Uncertainty Regarding Patents and Proprietary Rights." Raw Materials Supply The Company imports all of the plant material it screens from foreign countries, particularly from countries in Latin and South America, Southeast Asia and Africa. Shaman's relationships with botanical organizations in tropical regions have enabled the Company to set up large-scale supply arrangements for the raw material from which some of its lead products are derived. For example, the plant material required for SP-303 is found in at least seven Latin and South American countries and can be harvested in a sustainable manner where work forces already exist. Presently, Shaman is harvesting approximately 12,000 kilograms of the SP-303 source plant per year from South and Central America, pursuant to supply agreements with corporations working in those regions. The SP-303 source plant occurs naturally in these areas and, after harvesting, can be regenerated to maturity in seven years. Shaman is currently engaged in setting up market-scale, long-term acquisition of quantities of material adequate to meet projected commercial demands for the launch and sale of Provir. Shaman requires that all large-scale plant collections be conducted in a sustainable manner, which could include replanting in areas of intensive wild harvesting. In the case of SP-303, the source plant can be sustainably harvested because it grows spontaneously with minimal management. Shaman works with communities and cooperatives in South and Latin America to harvest the SP-303 source plant and other source plants in a regenerable manner. These communities and cooperatives, many of which receive support from national and international government agencies, are experienced in the sustainable harvest of other tropical forest products, including natural rubber, nuts and fruits. Company policy also requires that each source plant targeted for large-scale compound isolation must have multi-country sources of supply or be economically synthesizable. This policy reduces the risks associated with using foreign suppliers, such as political or economic instability. Shaman has entered into supply agreements with companies working in Central and South America pursuant to which they will supply certain quantities of Shaman's commercial requirements of the raw material used to produce SP-303 from their countries. These companies work with cooperatives of indigenous peoples to supply source plants to Shaman, to transfer material information to Shaman 11 relating to improvements in the collection and harvesting of the raw material, and to improve sustainable harvesting techniques in order to create a model of sustainable production in tropical forests. Although the Company has developed multi-country sources of supply for its key plant materials and has entered into long-term supply agreements for the source material for SP-303, there can be no assurance of a continual source of supply of these materials. See "Risk Factors--Dependence on Sources of Supply." When it is economically advantageous and technically feasible to synthesize a compound rather than extract it from raw plant material, the Company will utilize large-scale chemical synthesis to obtain a sufficient supply of such compound in order to satisfy its commercial requirements. However, there can be no assurance that the Company will be successful in synthesizing any such products. Competition Competition in the pharmaceutical industry is extremely intense. The principal factors upon which such competition is based include therapeutic efficacy, side-effect profile, ease of use, safety, physician acceptance, patient compliance, marketing, distribution and price. Many treatments for infectious and metabolic diseases exist and additional therapeutics are under development, including other naturally-sourced pharmaceuticals. To the extent these therapeutics address the disease indications on which the Company has focused, they may represent significant competition. Many pharmaceutical companies have significantly greater research and development capabilities, as well as substantially greater marketing, financial and human resources than the Company. In addition, many of these competitors have significantly greater experience than the Company in undertaking preclinical testing and human clinical trials of new pharmaceutical products and obtaining regulatory approvals of such products. These companies may represent significant long-term competition for the Company. There can be no assurance that developments by other pharmaceutical companies will not render Shaman's products or technologies obsolete or noncompetitive, or that the Company will be able to keep pace with technological developments of its competitors. Many of the Company's competitors have developed, or are in the process of developing, technologies that are, or in the future may be, the basis for competitive products. Some of these products may have an entirely different approach or means of accomplishing the desired therapeutic effect than products being developed by the Company. These competing products may be more effective and less costly than the products developed by Shaman. Government Regulation The research and development, manufacture and marketing of Shaman's products are subject to substantial regulation by the FDA in the United States and by comparable authorities in other countries. These national agencies and other federal, state and local entities regulate, among other things, research and development activities and the testing, manufacture, safety, effectiveness, labeling, storage, record keeping, approval, advertising and promotion of the Company's products. The process required by the FDA before the Company's products may be marketed in the United States generally involves the following: (i) preclinical laboratory and animal tests; (ii) submission to the FDA of an IND, which must become effective before human clinical testing may commence; (iii) adequate and well-controlled human clinical trials to establish the safety and efficacy of the proposed drug for its intended indications; (iv) the submission to the FDA of an NDA; (v) satisfactory completion of an FDA inspection of the manufacturing facilities at which the product is made to assess compliance with GMP. The testing and approval process requires substantial time, effort and financial resources. 12 Preclinical tests include laboratory evaluation of the product as well as animal studies to assess the potential safety and efficacy of the product. The results of the preclinical tests, together with manufacturing information and analytical data, are submitted to the FDA as part of the IND, which must become effective before human clinical trials may commence. The IND will automatically become effective 30 days after receipt by the FDA, unless the FDA before that time raises concerns or questions about the conduct of the trials as outlined in the IND. In such cases the IND sponsor and the FDA must resolve any outstanding concerns before clinical trials can proceed. There can be no assurance that submission of an IND will result in FDA authorization to commence clinical trials. Clinical trials involve the administration of the investigational products to healthy volunteers or patients under the supervision of a qualified principal investigator. Further, each clinical study must be reviewed and approved by an independent Institutional Review Board ("IRB") at each institution at which the study will be conducted. The IRB will consider, among other things, ethical factors, the safety of human subjects and the possible liability of the institution. Clinical trials are typically conducted in three sequential phases which may overlap. Phase I usually involves the initial introduction of the drug into healthy human subjects where the product is tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion. Phase II involves studies in a limited patient population to (i) determine the efficacy of the product for specific targeted indications, (ii) determine dose tolerance and optimal dose and (iii) identify possible adverse effects and safety risks. When Phase II evaluations demonstrate that the product is effective and has an acceptable safety profile, Phase III trials are undertaken to further evaluate clinical efficacy and to further test for safety in an expanded patient population at geographically-dispersed clinical study sites. The FDA or the sponsor may suspend clinical trials at any point in this process for a variety of reasons, including either party's belief that clinical subjects are being exposed to an unacceptable health risk. Occasionally, the FDA will require Phase IV "Post-Marketing Trials" which are conducted after FDA clearance to gain additional experience from the treatment of patients in the intended therapeutic area. Other Phase IV commitments might be additional toxicology or pharmacology studies. After completion of the required testing, generally an NDA is submitted. FDA approval of the NDA is required before marketing may begin in the United States. The NDA must include the results of extensive clinical and other testing and the compilation of data relating to the product's chemistry, pharmacology and manufacture, the cost of all of which is substantial. The FDA reviews all NDAs submitted before it accepts them for filing and may request additional information rather than accept an NDA for filing. In such an event, the NDA must be resubmitted with the additional information and, again, is subject to review before filing. Once the submission is accepted for filing, the FDA begins an in-depth review of the NDA. Under the Federal Food, Drug and Cosmetic Act, the FDA has 180 days in which to review the NDA and respond to the applicant. The review is often extended by mutual agreements of the sponsor and the FDA, or a major amendment to the submission. The FDA may refer the application to the appropriate advisory committee for review, evaluation and a recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an advisory committee, but generally follows the committee's recommendation. If evaluations of the NDA and the manufacturing facilities are favorable, the FDA may issue either an approval letter or an approvable letter, which usually 13 contains a number of conditions that must be met in order to secure final approval of an NDA. When and if those conditions have been met to the FDA's satisfaction, the FDA will issue an approval letter, authorizing commercial marketing of the drug for certain indications. If the FDA's evaluation of the NDA submission or manufacturing facilities is not favorable, the FDA may refuse to approve the NDA or issue a not approvable letter. Each drug product manufacturing establishment that supplies drugs to the U.S. market must be registered with, and be approved by, the FDA prior to commencing commercial production, and is subject to biennial inspections by the FDA for GMP compliance after an NDA has been approved. In addition, drug product manufacturing establishments located in California also must be licensed by the State of California. The Company will also be subject to a variety of foreign regulations governing clinical trials, registrations and sales of its products. Whether or not FDA approval has been obtained, approval of a product by comparable regulatory authorities of foreign countries must be obtained prior to marketing the product in those countries. The approval process varies from country to country and the time needed to secure approval may be longer or shorter than that required for FDA approval. The Healing Forest Conservancy In January 1990, Shaman formed The Healing Forest Conservancy, a California not-for-profit public benefit corporation (the "Conservancy"), which is dedicated to maintaining global plant biodiversity. The Conservancy focuses on conserving plants that have been used traditionally for medicinal purposes. Shaman has donated 13,333 shares of Common Stock to the Conservancy's endowment fund. The Company also plans to donate additional funds when it has achieved profits from product sales, if any, to provide benefits to indigenous peoples in the countries where Shaman's source plants are obtained. The Conservancy is also soliciting private donations to fund its operations and conservation efforts. Employees As of February 27, 1998, the Company had 106 employees. Of these employees, 72 are dedicated to research, development, quality assurance and quality control, regulatory affairs and preclinical testing. Thirty-four of the Company's full-time employees hold a Ph.D. or M.D. In addition, the Company currently fills 15 positions through the use of temporary staff and consultants. Scientific Strategy Team Shaman's Scientific Strategy Team ("SST") consists of an interdisciplinary group of ethnobotanists, scientists, pharmacologists, physicians, pharmacists and Company personnel. Several members of the SST who are actively working in the field have agreed to exclusively advise the Company in connection with medical and ethnobotanical matters and to refrain from consulting with other pharmaceutical companies on all ethnobotanical matters. Some members may have collaborative relationships with other pharmaceutical firms for random collection of plants on a contract basis. The principal criteria used in selecting members of the SST are breadth of the scientific discipline, recognized scientific excellence in their fields, and ability to contribute to the team evaluation process. The Company relies on the SST to identify plant candidates for Shaman's botanical screening process and to evaluate the information obtained about these candidates, both in the field and in literature. SST members who are not employees of the Company are compensated with stock options for their 14 general contributions throughout the year, and are paid $1,000 per day for participation at the SST meetings, which occur approximately every 12 months. Shaman also pays SST members for any additional consulting services and field expeditions conducted on behalf of the Company. The SST includes the following members: Edward F.

The Company's actual results could differ materially from the results discussed in the forward-looking statements. Factors that could cause or contribute to such differences include those discussed in "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations," and elsewhere in this Form 10-K. Early Stage of Development; Technological Uncertainty. Shaman has not yet completed the development of any products. Many of the Company's products will require significant additional clinical testing and investment prior to commercialization. Products for therapeutic use in human health care must be evaluated in extensive human clinical trials to determine their safety and efficacy as part of a lengthy process to obtain government approval. The Company's Provir, nikkomycin Z and SP-134101 products are each in clinical development. Positive results for any of these products in a clinical trial do not necessarily assure that positive results will be obtained in future clinical trials or that government approval to commercialize the products will be obtained. Clinical trials may be terminated at any time for many reasons, including toxicity or adverse event reporting. There can be no assurance that any of the Company's products will be successfully developed, enter into human clinical trials, prove to be safe and efficacious in clinical trials, meet applicable regulatory standards, obtain required regulatory approvals, be capable of being produced in commercial quantities at reasonable costs or be successfully marketed or that the Company will not encounter problems in clinical trials that will cause the Company to delay or suspend product development. Failure of any of the Company's products to be commercialized could have a material adverse effect on the Company's business, financial condition and results of operations. History of Operating Losses; Products Still in Development; Future Profitability Uncertain. Shaman was incorporated in 1989 and has experienced significant operating losses in each of its fiscal years since operations began. As of December 31, 1997, the Company's accumulated deficit was approximately $111.9 million. The Company has not generated any product revenues and expects to incur substantial operating losses over the next several years. All of Shaman's products and compounds are in research and development, which require substantial expenditures of funds. In order to generate revenues or profits, the Company, alone or with others, must successfully develop, test, obtain regulatory approval for and market its potential products. No assurance can be given that Shaman's product development efforts will be successful, that required regulatory approvals will be obtained, or that the products, if developed and introduced, will be successfully marketed or will achieve market acceptance. No Assurance of Successful Product Development. The Company's research and development programs are at various stages of development, ranging from the research stage to clinical trials. Substantial additional research and development will be necessary in order for the Company to move additional product candidates into clinical testing, and there can be no assurance that any of the Company's research and development efforts on these or other potential products, including Provir, nikkomycin Z, and SP-134101 will lead to development of products that are shown to be safe and effective in clinical trials. In addition, there can be no assurance that any such products will meet applicable regulatory standards, be capable of being produced in commercial quantities at acceptable costs, be eligible for third party reimbursement from governmental or private insurers, be successfully marketed or achieve market acceptance. Further, the Company's products may prove to have undesirable or unintended side 17 effects that may prevent or limit their commercial use. The Company may find, at any stage of this complex product development process, that products that appeared promising in preclinical studies or Phase I and Phase II clinical trials do not demonstrate efficacy in larger-scale, Phase III clinical trials and do not receive regulatory approvals. Accordingly, any product development program undertaken by the Company may be curtailed, redirected, suspended or eliminated at any time. In addition, there can be no assurance that the Company's testing and development schedules will be met. Any failure to meet such schedules could have a material adverse effect on the Company's business, financial condition and results of operations. The Company's clinical trials may be delayed by many factors, including, but not limited to: slower than anticipated patient enrollment; difficulty in finding a sufficient number of patients fitting the appropriate trial profile; difficulties in the acquisition of sufficient supplies of clinical trial materials; or, failure to show efficacy in clinical trials or adverse events occurring during the clinical trials. Completion of testing, studies and trials may take several years, and the length of time varies substantially with the type, complexity, novelty and intended use of the product. In addition, data obtained from preclinical and clinical activities are susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. Delays or rejections may be encountered based upon many factors, including changes in regulatory policy during the period of product development and could have a material adverse effect on the Company's business, financial condition and results of operations. See "Business--Government Regulation." Future Capital Needs; Uncertainty of Additional Funding. The Company will require substantial additional funds to conduct the development and testing of its potential products and to manufacture and market any products that may be developed. The Company's future capital requirements will depend on numerous factors, including the progress of its research and development programs, the progress of preclinical and clinical testing, the time and costs involved in obtaining regulatory approvals, the cost of filing, prosecuting, defending and enforcing patent claims and other intellectual property rights, competing technological and market developments, changes in the Company's existing collaborative and licensing relationships, the ability of the Company to establish additional collaborative relationships for the manufacture and marketing of its potential products, and the purchase of additional capital equipment. In addition, Note Purchase Agreements entered into by the Company in connection with the 1997 Private Placement, provide that under certain circumstances, the Company would be required to redeem all or some portion of the $10.4 million principal due thereunder, which redemption could significantly accelerate the Company's cash expenditures and capital requirements beyond the levels currently anticipated. The Company intends to seek additional funding through public or private equity or debt financings, collaborative arrangements or from other sources. The Company may seek additional capital at any time that it deems market conditions to be favorable. If additional funds are raised by issuing equity securities, significant dilution to existing stockholders may result. In the event that additional funds are obtained through collaborative agreements, such agreements may require the company to relinquish rights to certain of its technologies, product candidates, products or marketing territories that the Company would otherwise seek to develop or commercialize itself. There can be no assurance that additional financing will be available on acceptable terms or at all. If adequate funds are not available, the Company may be required to delay, scale back or eliminate one or more of its research, discovery or development programs, which could have a material adverse effect on the Company's business, financial condition and results of operations. See "Management's Discussion and Analysis of Financial Condition and Results of Operations." Uncertainties Associated with Clinical Trials. Shaman has conducted, and plans to continue to conduct, extensive and costly clinical trials to assess the safety and efficacy of its potential products. The rate of completion of the Company's clinical trials is dependent upon, among other factors, the rate of completion and approval of trial protocols, the availability of funds for trials and the rate of 18 patient enrollment. Patient enrollment is a function of many factors, including the nature of the Company's clinical trial protocols, existence of competing protocols, size of patient population, proximity of patients to clinical sites and eligibility criteria for the study. Delays in patient enrollment will result in increased costs and delays, which could have a material adverse effect on the Company's ability to complete clinical trials in a timely fashion. The Company cannot assure that patients enrolled in its clinical trials will respond to the Company's product candidates. Setbacks are to be expected in conducting human clinical trials. Failure to comply with the U.S. FDA regulations applicable to such testing can result in delay, suspension or cancellation of such testing, and/or refusal by the FDA to accept the results of such testing. In addition, the FDA or the Company may suspend clinical trials at any time if either of them concludes that any patients participating in any such trial are being exposed to unacceptable health risks. Further, there can be no assurance that human clinical testing will demonstrate that any current or future product candidate is safe or effective or that data derived from any such study will be suitable for submission to the FDA or other regulatory authorities. Failure of the Company's clinical trials to demonstrate safety or efficacy in humans could cause the delay, suspension, or termination of any product program and could have a material adverse effect on the Company's business, financial condition and results of operations. Dependence on Collaborative Relationships. The Company's research and development efforts in its diabetes program and, to a lesser extent, in its other programs, is dependent upon its arrangements with Lipha/Merck and Ono and the compliance of such partners with the terms and conditions of such collaborative agreements including, without limitation, providing funding for research and development efforts and the achievement of milestones and assisting the Company in its research and development efforts. These partners may develop products that may compete with those of the Company. The amount and timing of resources they allocate to these programs is not within the Company's control. There can be no assurance that these partners will perform their obligations as expected or that any significant revenues will ultimately be derived from such agreements. The Company's agreement with Ono may be terminated in the event Ono determines further development of compounds is not warranted, provided certain other conditions are met. Termination of either agreement is subject to certain surviving obligations. If one or more such partners elected to terminate their relationships with the Company, or if the Company or its partners fail to achieve targeted milestones, it could have a material adverse effect on the Company's ability to fund such programs, or to develop any products on a collaborative basis with such partners. In addition, the Company may seek future collaborative agreements in order to commercialize additional product candidates or that any such agreements will be successful. There can be no assurance that the Company will be able to enter into such additional agreements and any failure could have a material effect on the Company's business, financial condition, and results of operations. See "Business--Collaborative Relationships and License Agreements." Rapid Technological Change and Substantial Competition. The pharmaceutical industry is subject to rapid and substantial technological change. Technological competition from pharmaceutical and biotechnology companies and universities is intense. Many of these entities have significantly greater research and development capabilities, as well as substantial marketing, manufacturing, financial and managerial resources, and represent significant competition for the Company. There can be no assurance that developments by others will not render the Company's products or technologies noncompetitive or that the Company will be able to keep pace with technological developments. Competitors have developed or are in the process of developing technologies that are, or in the future may be, the basis for competitive products. Some of these products may have an entirely different approach or means of accomplishing the desired therapeutic effect than products developed by the Company. These competing products may be more effective and less costly than the products developed by the Company. In addition, other forms of medical treatment may offer competition to the Company's products. The development of competing compounds could have a material adverse effect on the Company's business, 19 financial condition or results of operations. See "Business--Competition." Government Regulation; No Assurance of Regulatory Approvals. All new drugs, including the Company's products under development, are subject to extensive and rigorous regulation by the federal government, principally the FDA, and comparable agencies in state and local jurisdictions and in foreign countries. These authorities impose substantial requirements upon the preclinical and clinical testing, manufacturing and marketing of pharmaceutical products. The steps required before a drug may be approved for marketing in the United States generally include (i) preclinical laboratory and animal tests, (ii) the submission to the FDA of an IND for human clinical testing, (iii) adequate and well controlled human clinical trials to establish the safety and efficacy of the drug, (iv) submission to the FDA of an NDA, and (v) satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the drug is made to assess compliance with GMP. Lengthy and detailed preclinical and clinical testing, validation of manufacturing and quality control processes, and other costly and time-consuming procedures are required. Satisfaction of these requirements typically takes several years and the time needed to satisfy them may vary substantially, based on the type, complexity and novelty of the pharmaceutical product. The effect of government regulation may be to delay or to prevent marketing of potential products for a considerable period of time and to impose costly procedures upon the Company's activities. There can be no assurance that the FDA or any other regulatory agency will grant approval for any products developed by the Company on a timely basis, or at all. Success in preclinical or early stage clinical trials does not assure success in later stage clinical trials. Data obtained from preclinical and clinical activities are susceptible to varying interpretations which could delay, limit or prevent regulatory approval. If regulatory approval of a product is granted, such approval may impose limitations on the indicated uses for which a product may be marketed. Further, even if regulatory approval is obtained, later discovery of previously unknown problems with a product may result in restrictions on the product, including withdrawal of the product from the market. Any delay or failure in obtaining regulatory approvals would have a material adverse effect on the Company's business, financial condition and results of operation. Among the conditions for FDA approval of a pharmaceutical product is the requirement that the manufacturer's (either the Company's own or a third-party manufacturer) quality control and manufacturing procedures conform to current GMP, which must be followed at all times. The FDA strictly enforces GMP requirements through periodic unannounced inspections. There can be no assurance that the FDA will determine that the facilities and manufacturing procedures of the Company or any third-party manufacturer of the Company's planned products will conform to GMP requirements. Additionally, the Company or its third-party manufacturer must pass a pre-approval inspection of its manufacturing facilities by the FDA before obtaining marketing approval. Failure to comply with applicable regulatory requirements may result in penalties such as restrictions on a product's marketing or withdrawal of a product from the market. The FDA's policies may change and additional government regulations may be promulgated which could prevent or delay regulatory approval of the Company's potential products. Moreover, increased attention to the containment of health care costs in the United States could result in new government regulations that could have a material adverse effect on the Company's business. The Company is unable to predict the likelihood of adverse governmental regulation that might arise from future legislative or administrative action, either in the United States or abroad. See "Business--Government Regulation." Dependence on Sources of Supply. The Company currently imports all of the plant materials from which its products are derived from countries in South and Latin America, Africa and Southeast Asia. 20 To the extent that its products cannot be economically synthesized or otherwise produced, the Company will continue to be dependent upon a supply of raw plant material. The Company does not have formal agreements in place with all of its suppliers. In addition, a continued source of plant supply is subject to the risks inherent in international trade. These risks include unexpected changes in regulatory requirements, exchange rates, tariffs and barriers, difficulties in coordinating and managing foreign operations, political instability and potentially adverse tax consequences. Interruptions in supply or material increases in the cost of supply could have a material adverse effect on the Company's business, financial condition and results of operations. In addition, tropical rain forests, and certain irreplaceable plant resources therein, are currently threatened with destruction. In the event portions of the rain forests are destroyed which contain the source material from which Shaman's current or future products are derived, such destruction could have a material adverse effect on the Company's business, financial condition and results of operations. Limited Manufacturing and Marketing Experience and Capacity. The Company currently produces products only in quantities necessary for clinical trials and does not have the staff or facilities necessary to manufacture products in commercial quantities. As a result, the Company must rely on collaborative partners or third-party manufacturing facilities, which may not be available on commercially acceptable terms adequate for Shaman's long-term needs. If the Company should encounter delays or difficulties in establishing relationships with qualified manufacturers to produce, package and distribute its finished products, clinical trials, regulatory filings, market introduction and subsequent sales of such products could be adversely affected. Contract manufacturers must adhere to GMP regulations strictly enforced by the FDA on an ongoing basis through its facilities inspection program. Contract manufacturing facilities must pass a pre-approval plant inspection before the FDA will approve an NDA. Certain material manufacturing changes that occur after approval are also subject to FDA review and clearance or approval. There can be no assurance that the FDA or other regulatory agencies will approve the process or the facilities by which any of the Company's products may be manufactured. The Company's dependence on third parties for the manufacture of products may adversely affect the Company's ability to develop and deliver products on a timely and competitive basis. Should the Company be required to manufacture products itself, the Company will be subject to the regulatory requirements described above, to similar risks regarding delays or difficulties encountered in manufacturing any such products and will require substantial additional capital. There can be no assurance that the Company will be able to manufacture any such products successfully or in a cost-effective manner. The Company currently has no sales staff. To the extent that the Company does not or is unable to enter into co-promotion agreements or to arrange for third party distribution of its products, significant additional resources will be required to develop a complete marketing and sales force. There can be no assurance that the Company will be able to enter into collaborative agreements or successfully establish a marketing and sales force. Uncertainty Regarding Patents and Proprietary Rights. The Company's success will depend in large part on its ability to obtain and maintain patents, protect trade secrets and operate without infringing upon the proprietary rights of others. Moreover, competitors may have filed patent applications, may have been issued patents or may obtain additional patents and proprietary rights relating to products or processes competitive with those of the Company. There can be no assurance that the Company's patent applications will be approved, that the Company will develop additional proprietary products that are patentable, that any issued patents will provide the Company with adequate protection for its inventions or will not be challenged by others, or that the patents of others will not impair the ability of the Company to commercialize its products. The patent position of firms in the pharmaceutical industry generally is highly uncertain, involves complex legal and factual questions, and has recently been the subject of much litigation. No consistent policy has emerged from 21 the U.S. Patent and Trademark Office or the courts regarding the breadth of claims allowed or the degree of protection afforded under pharmaceutical patents. There can be no assurance that others will not independently develop similar products, duplicate any of the Company's products or design around any patents of the Company. A number of pharmaceutical 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. Some of these technologies, applications or patents may conflict with the Company's technologies or patent applications. The European Patent Office, the French Patent Office, the German Patent Office and the Australian Patent Office, have each granted a patent containing broad claims to proanthocyanidin polymer compositions (and methods of use of such compositions), which are similar to the Company's specific proanthocyanidin polymer composition, to Leon Cariel and the Institut des Substances Vegetales. The effective filing date of these patents is prior to the effective filing date of the Company's foreign pending patent application in Europe. Certain of the foreign patents have been granted in jurisdictions where examination is not rigorous. The Company has instituted an Opposition in the European Patent Office against granted European Patent No. 472531 owned by Leon Cariel and Institut des Substances Vegetales. Based on opinions of foreign counsel, the Company believes that the granted claims are invalid and intends to vigorously prosecute the Opposition. There can be no assurance that the Company will be successful in having the granted European patent revoked or the claims sufficiently narrowed so as not to potentially cover the Company's proanthocyanidin polymer composition and methods of use. There can be no assurance that Leon Cariel and the Institut des Substances Vegetales will not assert claims relating to this patent against the Company. There can be no assurance that the Company would be able to obtain a license to this patent at all, or at reasonable cost, or be able to develop or obtain alternative technology to use in Europe or elsewhere. The earlier effective filing date of this patent could limit the scope of the patents, if any, that the Company may be able to obtain or result in the denial of the Company's patent applications in Europe or elsewhere. In the United States, the Patent and Trademark Office has rendered judgment in an Interference declared between the Company's issued patent covering its specific proanthocyanidin polymer composition and certain claims of U.S. application corresponding to the granted European patent of Leon Cariel and the Institut des Substances Vegetales by Daniel Jean and Leon Cariel. Judgment was awarded to the Company. Since the period for appeal has passed, this judgment is now final. Additionally, in connection with the Interference proceeding, the Company has had an opportunity to review the claims and file history of the Daniel Jean and Leon Cariel patent application which, under U.S. patent law, are kept confidential. One broad claim, in particular, of the Daniel Jean and Leon Cariel patent application, which was not involved in the Interference proceeding and which has been indicated to be allowable, covers a large variety of proanthocyanidin polymers. Based on opinion of counsel, the Company believes that this broad claim is subject to attack as invalid in view of prior art. Based on knowledge of the Company's specific proanthocyanidin polymer composition, the Company believes that the manufacture, use or sale of its specific proanthocyanidin polymer composition would not constitute infringement of this broad claim, once it issues. There can be no assurances, however, that the Company would prevail should an action for infringement of such claim be commenced. In addition, if patents that cover the Company's activities have been or are issued to other companies, there can be no assurance that the Company would be able to obtain licenses to these patents at a reasonable cost, or at all, or be able to develop or obtain alternative technology. If the Company does not obtain such licenses, it could encounter delays or be precluded from introducing products to the market. Litigation may be necessary to defend against or assert claims of 22 infringement, to enforce patents issued to the Company or to protect trade secrets or know-how owned by the Company. Additional interference proceedings may be declared or necessary to determine issues of invention; such litigation and/or interference proceedings could result in substantial cost to and diversion of effort by, and may have a material adverse effect on, the Company. In addition, there can be no assurance that these efforts by the Company will be successful. The Company's competitive position is also dependent upon unpatented trade secrets. There can be no assurance that others will not independently develop substantially equivalent proprietary information and techniques or otherwise gain access to the Company's trade secrets, that such trade secrets will not be disclosed or that the Company can effectively protect its rights to unpatented trade secrets. To the extent that the Company or its consultants or research collaborators use intellectual property owned by others in their work for the Company, disputes also may arise as to the rights in related or resulting know-how and inventions. See "Business--Patents and Proprietary Rights." Patent applications in the United States are generally maintained in secrecy until patents are issued. Since publication of discoveries in the scientific or patent literature tends to lag behind actual discoveries by several months, Shaman cannot be certain that it was the first to discover compositions covered by its pending patent applications or the first to file patent applications on such compositions. There can be no assurance that the Company's patent applications will result in issued patents or that any of its issued patents will afford comprehensive protection against potential infringement. The Company is prosecuting its patent applications with the PTO but the Company does not know whether any of its applications will result in the issuance of any patents or, if any patents are issued, whether any issued patent will provide significant proprietary protection or will be circumvented or invalidated. During the course of patent prosecution, patent applications are evaluated, inter alia, for utility, novelty, non-obviousness and enablement. The PTO may require that the claims of an initially filed patent application be amended if it is determined that the scope of the claims includes subject matter that is not useful, novel, non-obvious or enabled. Furthermore, in certain instances, the practice of a patentable invention may require a license from the holder of dominant patent rights. In cases where one party believes that it has a claim to an invention covered by a patent application or patent of a second party, the first party may provoke an interference proceeding in the PTO or such a proceeding may be declared by the PTO. In general, in an interference proceeding, the PTO would review the competing patents and/or patent applications to determine the validity of the competing claims, including but not limited to determining priority of invention. Any such determination would be subject to appeal in the appropriate U.S. federal courts. There can be no assurance that additional patents will be obtained by the Company or that issued patents will provide a substantial protection or be of commercial benefit to the Company. The issuance of a patent is not conclusive as to its validity or enforceability, nor does it provide the patent holder with freedom to operate without infringing the patent rights of others. A patent could be challenged by litigation and, if the outcome of such litigation were adverse to the patent holder, competitors could be free to use the subject matter covered by the patent, or the patent holder may license the technology to others in settlement of such litigation. The invalidation of patents owned by or licensed to the Company or non-approval of pending patent applications could create increased competition, with potential adverse effects on the Company and its business prospects. In addition, there can be no assurance that any applications of the Company's technology will not infringe patents or proprietary rights of others or that licenses that might be required as a result of such infringement for the Company's processes or products would be available on commercially reasonable terms, if at all. The Company cannot predict whether its or its competitors' patent applications will result in valid patents being issued. Litigation, which could result in substantial cost to the Company, may also 23 be necessary to enforce the Company's patent and proprietary rights and/or to determine the scope and validity of others' proprietary rights. The Company may participate in interference proceedings that may in the future be declared by the U.S. Patent and Trademark Office, which could result in substantial cost to the Company. There can be no assurance that the outcome of any such litigation or interference proceedings will be favorable to the Company or that the Company will be able to obtain licenses to technology that it may require or that, if obtainable, such technology can be licensed at a reasonable cost. Year 2000 Compliance. The Company is in the process of assessing the impact of year 2000 on its operations and systems, including those of its suppliers and collaborators and other third parties. Management is in the process of formalizing its assessment procedures and developing a plan to address identified issues, if any. To date, the Company has evaluated its financial and accounting systems and concluded that they are not and will not be materially affected by the year 2000. The Company does not yet know the extent, if any, of the impact of the year 2000 on its other systems and equipment or those of third parties with which the Company does business. There can be no assurance that third parties, such as suppliers, clinical research organizations and collabortive parties, are using systems that are year 2000 compliant or will address any year 2000 issues in a timely fashion, or at all. Any year 2000 compliance problems of either the Company, its suppliers, its clinical research organizations, or its collaborative partners could have a material adverse effect on the Company's business, operating results and financial conditions. Uncertainty of Product Pricing, Reimbursement and Related Matters. The Company's business may be materially adversely affected by the continuing efforts of governmental and third party payers to contain or reduce the costs of health care through various means. For example, in certain foreign markets, the pricing or profitability of health care products is subject to government control. In the United States, there have been, and the Company expects there will continue to be, a number of federal and state proposals to implement similar government control. While the Company cannot predict whether any such legislative or regulatory proposals or reforms will be adopted, the announcement of such proposals or reforms could have a material adverse effect on the Company's ability to raise capital or form collaborations, and the adoption of such proposals or reforms could have a material adverse effect on the Company's business, financial condition or results of operations. In addition, in both the United States and elsewhere, sales of health care products are dependent in part on the availability of reimbursement from third party payers, such as government and private insurance plans. Significant uncertainty exists as to the reimbursement status of newly approved health care products, and third party payers are increasingly challenging the prices charged for medical products and services. If the Company succeeds in bringing one or more products to the market, there can be no assurance that reimbursement from third party payers will be available or will be sufficient to allow the Company to sell its products on a competitive or profitable basis. Possible Volatility of Stock Price. From time to time, the stock market has experienced significant price and volume fluctuations that may be unrelated to the operating performance of particular companies or industries. In addition, the market price of the Company's Common Stock, like the stock prices of many publicly traded biotechnology and smaller pharmaceutical companies, has been and may continue to be highly volatile. Announcements of technological innovations, regulatory matters or new commercial products by the Company or its competitors, developments or disputes concerning patent or proprietary rights, publicity regarding actual or potential medical results relating to products under development by the Company or its competitors, regulatory developments in both the United States and foreign countries, public concern as to the safety of pharmaceutical products, and economic and other external factors, as well as period-to-period fluctuations in financial results, may have a significant impact on the market price of Shaman's Common Stock. See "Part II--Item 5: Market for Registrant's Common Stock and Related Stockholder Matters." 24 Environmental Regulation. In connection with its research and development activities and manufacturing of clinical trial materials, the Company is subject to federal, state and local laws, rules, regulations and policies governing the use, generation, manufacture, storage, air emission, effluent discharge, handling and disposal of certain materials and wastes. Although the Company believes that it has complied with these laws and regulations in all material respects and has not been required to take any action to correct any noncompliance, there can be no assurance that the Company will not be required to incur significant costs to comply with environmental and health and safety regulations in the future. The Company's research and development activities involve 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 such liability could exceed the resources of the Company. Anti-Takeover Effect of Delaware Law and Certain Charter and Bylaws Provisions. Certain provisions of the Company's Certificate of Incorporation and Bylaws may have the effect of making it more difficult for a third party to acquire, or discouraging a third party from attempting to acquire, control of the Company. Such provisions could limit the price that certain investors might be willing to pay in the future for shares of the Company's Common Stock. The Company's Board of Directors has the authority to issue up to 600,000 additional shares of Preferred Stock and to determine the price, rights, preferences, privileges and restrictions of those shares without any further vote or action by the stockholders. The rights of the holders of Common Stock will be subject to, and may be adversely affected by, the rights of the holders of any Preferred Stock that may be issued in the future. The issuance of Preferred Stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire a majority of the outstanding voting stock of the Company. The Company has no present plans to issue shares of Preferred Stock. Certain provisions of Delaware law applicable to the Company could also delay or make more difficult a merger, tender offer or proxy contest involving the Company, including Section 203 of the Delaware General Corporation Law, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years unless certain conditions are met. Product Liability Exposure; Limited Insurance Coverage. The Company's business exposes it to potential product liability risks which are inherent in the development, testing, manufacture, marketing and sale of pharmaceutical products. Product liability insurance for the pharmaceutical industry generally is expensive. There can be no assurance that the Company's present product liability insurance coverage is adequate. Such existing coverage will not be adequate as the Company further develops its products, and no assurance can be given that adequate insurance coverage against all potential claims will be available in sufficient amounts or at a reasonable cost. Limitation of Liability and Indemnification. The Company's Certificate of Incorporation limits, to the maximum extent permitted by Delaware Law, the personal liability of directors for monetary damages for breach of their fiduciary duties as a director. The Company's Bylaws provide that the Company shall indemnify its officers and directors and may indemnify its employees and other agents to the fullest extent permitted by law. The Company has entered into indemnification agreements with its officers and directors containing provisions which are in some respects broader than the specific indemnification provisions contained in Delaware Law. The indemnification agreements may require the Company, among other things, to indemnify such officers and directors against certain liabilities that may arise by reason of their status or service as directors or officers (other than liabilities arising 25 from willful misconduct of a culpable nature), to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified, and to obtain directors' and officers' insurance, if available on reasonable terms. Section 145 of the Delaware Law provides that a corporation may indemnify a director, officer, employee or agent made or threatened to be made a party to an action by reason of the fact that he was a director, officer, employee or agent of the corporation or was serving at the request of the corporation against expenses actually and reasonably incurred in connection with such action if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. Delaware Law does not permit a corporation to eliminate a director's duty of care, and the provisions of the Company's Certificate of Incorporation have no effect on the availability of equitable remedies, such as injunction or rescission, for a director's breach of the duty of care. Dependence on Key Personnel. The Company's ability to maintain its competitive position depends in part upon the continued contributions of its key senior management. The Company's future performance also depends on its ability to attract and retain qualified management and scientific personnel. Competition for such personnel is intense, and there can be no assurance that the Company will be able to continue to attract, assimilate or retain other highly qualified technical and management personnel in the future. The loss of key personnel or the failure to recruit additional personnel or to develop needed expertise could have a material adverse effect on the Company's business, financial condition and results of operations. ITEM 2. PROPERTIES Shaman's headquarters are located in South San Francisco, California. The Company leases approximately 73,000 square feet for offices, laboratories, pilot manufacturing and preclinical testing in three adjacent buildings. An additional building with approximately 43,000 square feet becomes available to the Company in late 1999. The lease on these spaces expires February 28, 2003, and the Company has an option to renew the lease for two additional five-year periods. The South San Francisco facility serves as the principal site for preclinical research, clinical trial management, process development, quality assurance and quality control, regulatory and other affairs. The Company believes that its current facilities are suitable and adequate to meet its needs for the foreseeable future. Shaman anticipates it will be able to expand its facilities to nearby locations as the need develops. There can be no assurance however, that such space will be available on favorable terms, if at all. ITEM 3. LEGAL PROCEEDINGS The Company has initiated arbitration against Dr. Michael Tempesta with respect to a February 1990 license agreement. See "Business--Collaborative Relationships and License Agreements." Ms. Jacqueline Cossmon, the Company's former Vice President of investor and public relations filed a complaint against the Company with the Superior Court of the State of California, County of San Mateo on December 31, 1997 for wrongful termination and is seeking monetary damages. The Company denies any wrongdoing with respect to Ms. Cossmon and intends to vigorously defend this action. With the exception of the patent opposition proceeding in Europe, arbitration against Dr. Tempesta and Ms. Cossmon's action, the Company is not party to any other material legal proceedings. See "Risk Factors--Uncertainty Regarding Patents and Proprietary Rights." 26 ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITIES HOLDERS No matters were submitted to a vote of securities holders during the fourth quarter of the fiscal year ended December 31, 1997. 27 PART II ITEM 5. MARKET FOR REGISTRANT'S COMMON STOCK AND RELATED STOCKHOLDER MATTERS The Company's common stock trades on the Nasdaq National Market tier of the Nasdaq Stock Market under the symbol SHMN.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Overview Shaman Pharmaceuticals, Inc. ("Shaman" or the "Company") discovers and develops novel pharmaceutical products for major human diseases by isolating active compounds from tropical plants. The Company has three compounds in clinical development: Provir, an oral product for the treatment of AIDS-associated and watery diarrhea; nikkomycin Z, an oral antifungal for the treatment of systemic fungal infections; and SP-134101, an oral product for the treatment of Type II diabetes. Shaman maintains an active Type II diabetes research program which serves as the basis for its collaborations with Lipha s.a., a wholly-owned subsidiary of Merck KGaA, Darmstadt, Germany ("Lipha/Merck"), and with Ono Pharmaceutical Co., Ltd. ("Ono") of Osaka, Japan. The Company began operations in March 1990. To date, Shaman has not sold any products and does not anticipate receiving product revenue in the near future. The Company's accumulated deficit at December 31, 1997, was approximately $ 111.9 million. Shaman expects to continue to incur substantial and increasing losses over the next several years, due primarily to the expense of preclinical studies, clinical trials and its ongoing research program. The Company expects that losses will fluctuate from quarter to quarter and that such fluctuations could be substantial. Shaman has financed its research, development and administrative activities through various private and public equity financings, loans and debt financings, and collaborative agreements with pharmaceutical companies and, to a lesser extent, through equipment and leasehold improvement lease financings. Results of Operations for the Years Ended December 31, 1997, 1996 and 1995 The Company recorded collaborative revenues of $3.5 million, $3.4 million, and $2.2 million for 1997, 1996, and 1995, respectively. Revenues for 1997 resulted from the Company's on-going research funding from Ono and research funding from Shaman's collaboration with Lipha/Merck. Revenues for 1996 resulted from the Company's on-going research funding from Ono, an additional $1.0 million payment from Ono for enhanced rights to Shaman's antidiabetic compounds, and research payments and access fees from Shaman's collaboration with Lipha/Merck. Revenues in 1995 resulted solely from the Company's relationship with Ono, and included a one-time access fee associated with the May 1995 commencement of the collaboration. The Company expects that revenues from collaborative agreements will continue to fluctuate in the future as development of its various compounds proceeds and new products are partnered for development and commercialization. The Company incurred research and development expenses of $24.1 million, $19.1 million, and $17.6 million for 1997, 1996, and 1995, respectively. These expenses include salaries for scientific personnel, clinical development costs, laboratory supplies, patent protection and consulting fees, travel, plant collections, facilities expenses and other expenditures relating to research and product development. Research and development expenses increased $5.0 million in 1997 compared with 1996, and increased $1.5 million in 1996 compared with 1995. The increase in 1997 was primarily attributable to the Company's increased clinical development activities with respect to Provir, partially offset by reduced expenses for clinical development activities for nikkomycin Z. The increase in 1996 was primarily attributable to the Company's clinical development activities for Provir, as well as additional research and development activities with respect to nikkomycin Z, partially offset by reduced expenses for clinical development activities for Virend. Research and development expenses are expected to increase in 1998 as Provir enters Phase III clinical development for AIDS-associated diarrhea, other products continue through development and the Company actively maintains its diabetes research program. 30 General and administrative expenses were $4.8 million, $3.5 million and $3.7 million for 1997, 1996 and 1995, respectively. These expenses include administrative salaries, consulting, legal, travel and other operating expenses. General and administrative expenses increased $1.3 million in 1997 compared to 1996, and decreased $0.2 million in 1996 compared to 1995. The increase in 1997 was primarily attributable an increase in compensation and marketing research related to late stage clinical products, as well as additional legal expenses related to certain disputes related to the Company's intellectual property rights. The Company's expanded research and clinical activities in 1998 are not expected to require commensurate increases in general and administrative support. Interest income was $1.2 million, $1.1 million and $1.7 million for 1997, 1996 and 1995, respectively. Interest income increased $100,000 in 1997 compared with 1996 and decreased $600,000 in 1996 compared with 1995. Interest income fluctuations have been consistent with changes in average cash and investment balances with which the Company substantially funded its operations in 1997, 1996 and 1995. The balances of cash, cash equivalents and investments were $21.4 million, $16.5 million and $26.7 million at December 31, 1997, 1996 and 1995, respectively. Interest expense was $5.0 million, $603,000 and $569,000 for 1997, 1996 and 1995, respectively. Interest expense increased in 1997 compared with 1996 principally due to a $3.7 million non-cash interest charge related to the issuance of senior convertible notes in June 1997, as well as the interest expense related to the Company's secured debt financing in May 1997. Interest expense increased in 1996 compared with 1995 as the Company absorbed a full year's expense on its unsecured term loan. The Company's general policy is to finance capital equipment and tenant improvements on a long-term basis, and interest expense in the future will be dependent in part on the Company's capacity to finance its future equipment needs. At December 31, 1997, the Company had federal net operating loss carryforwards of approximately $ 102 million. The federal net operating loss carryforwards will expire at various dates beginning in 2004 through 2012, if not sooner utilized. Utilization of the net operating losses and credits is subject to a substantial annual limitation due to the "change in ownership" provisions of the Internal Revenue Code of 1986, as amended. The annual limitation may result in the expiration of net operating losses and credits before utilization. Liquidity and Capital Resources As of December 31, 1997, the Company's cash, cash equivalents, and investments totaled approximately $21.4 million, compared with $16.5 million at December 31, 1996. The net increase was primarily attributable to funds received from the private placement of senior convertible notes in June 1997, registered direct public offerings in January 1997 and April 1997, the secured loan entered into in May 1997, and research funding from Shaman's collaboration with Lipha/Merck and Ono. In June 1997, the Company privately issued $10.4 million of senior convertible notes ("The 1997 Private Placement"). The notes mature in August 2000 and bear interest at a rate of 5.5% per annum. Interest on the notes may be paid in Common Stock or cash at the Company's option. Initially, the notes were convertible into Common Stock of the Company at 100% of the low trading price during a designated time period prior to conversion provided that the conversion price will not be less than $5.50 per share. Starting in November 1997, the notes are convertible into Common Stock of the Company at a 10% discount from the low trading price during a designated time period prior to the conversion, with a floor of $5.50 through March 31, 1998, pursuant to a November 1997 understanding with the note holders to revise the terms of the note. In connection with this understanding, the Company issued to the note holders three-year warrrants to purchase an aggregate of 137,500 shares of common stock at an exercise price of $7.50 per share. The Company filed a registration statement with the SEC for the resale of shares issued upon conversion of these notes, which registration statement was declared effective on 31 August 29, 1997. Of the notes issued, $400,000 were issued to the placement agent as part of the placement fee. The Company paid the placement agent an additional $300,000 in cash. The placement fees and other offering costs have been capitalized in other assets as deferred issuance costs and are being amortized to interest expense over the life of the notes. The net proceeds totaled approximately $9.5 million after the placement agent's fees and other offering expenses. In May 1997, the Company obtained a $5.0 million, 36-month term loan to pay off pre-existing debt, finance capital asset acquisitions and finance continued research and clinical development of the Company's existing product candidates. The loan carries an interest rate of 14.58% and is payable in equal monthly installments over the term of the loan. The lender was granted ten-year warrants to purchase 200,000 shares of the Company's Common Stock at $6.25 per share. The Company has attributed a value of $648,000 to these warrants. This amount has been recorded as a discount on the related debt and is being amortized as interest expense over the term of the loan. In April 1997, the Company sold 1,600,000 shares of Common Stock at $4.97 per share in a registered direct public offering, marketed solely by the Company, which yielded gross proceeds of $7.95 million. The net proceeds of approximately $7.8 million from this offering will be used for the continued research and clinical development of the Company's existing product candidates. In January 1997, the Company sold 2,000,000 shares of Common Stock in a registered direct public offering for gross proceeds of $9.0 million. The net proceeds of approximately $8.1 million from this offering will be used for the continued research and clinical development of the Company's existing product candidates. In September 1996, the Company entered into a five-year collaborative agreement with Lipha/Merck to jointly develop Shaman's antihyperglycemic drugs. Upon signing the collaboration, the Company received an annual research fee of $1.5 million which is amortized to revenue over twelve months, as work is performed. The Company also received approximately $3.0 million for 388,918 shares of Common Stock priced at $7.71 per share, representing a 20% premium to the weighted average price of the Company's stock at the time of purchase. In exchange for development and marketing rights in all countries except Japan, South Korea, and Taiwan (which are covered under an earlier agreement between Shaman and Ono), Lipha/Merck will provide up to $9.0 million in research payments and up to $10.5 million in equity investments priced at a 20% premium to a multi-day volume weighted average price of the Company's common stock at the time of purchase. The agreement also provides for additional preclinical and clinical milestone payments to the Company in excess of $10.0 million per compound for each antihyperglycemic drug developed and commercialized. Lipha/Merck will bear all pre-clinical, clinical, regulatory and other development expenses associated with the compounds selected under the agreement. In addition, as products are commercialized, Shaman will receive royalties on all product sales outside the United States and up to 50% of the profits (if the Company exercises its co-promotion rights) or royalties on all product sales in the United States. Certain of the milestone payments will be credited against future royalty payments, if any, due to the Company from sales of products developed pursuant to the agreement. For the year ended December 31, 1997, Shaman recognized $1.5 million in revenue from the Lipha/Merck collaboration. Shaman also received $1.5 million for 200,787 shares of Common Stock priced at $7.47 per share, representing a 20% premium to the weighted average price of the Company's stock at the time of purchase. In July 1996, the Company closed a private placement (the "1996 Private Placement") pursuant to Regulation S under the Securities Act of 1933, as amended, in which it received gross proceeds of $3.3 million for the sale of 400,000 shares of Series A Convertible Preferred Stock and for the issuance of a six-year warrant to purchase 550,000 shares of the Company's Common Stock at an exercise price of 32 $10.18 per share. The Preferred Stock does not carry a dividend obligation and will convert into Common Stock no later than July 23, 1999 at a price per share between $6.00 and $8.15, depending on the market value of the Company's Common Stock during the period prior to conversion. Holders of preferred shares are entitled to a liquidation preference of $8.15 per share. In addition to the sale of Preferred Stock and warrant, the Company has the right, from time to time during the period beginning January 1997 and ending July 2000, to sell up to 1,200,000 additional shares of Common Stock to the investor at a formula price of 100% or 101% of a multi-day average of the Company's Common Stock price at the time of sale. If the Company exercises this right, the investor has the option to increase the shares purchased by up to an aggregate of 527,500 shares. Pursuant to the terms of the 1997 Private Placement, the Company may not exercise this right until late February 1998. The Company expects to incur substantial additional costs relating to the continued preclinical and clinical testing of its products, regulatory activities and research and development programs. The Company anticipates that its cash, cash equivalents and investment balances of approximately $21.4 million at December 31, 1997, the collaborative revenue committed by Lipha/Merck, Lipha/Merck's commitment to purchase additional equity and Shaman's additional rights to sell Common Stock under the 1996 Private Placement will be adequate to fund operations, including payments due under long-term obligations, through the end of 1998. Milestone payments which may be received by the Company from Ono and Lipha/Merck would extend the Company's capacity to finance its operations beyond that time. However, there can be no assurance that these milestones will be achieved, or that additional funding, if needed, will be available on reasonable terms, or at all. Long-term obligations increased $11.4 million in 1997 compared with 1996 primariy due to the issuance of $10.4 million senior convertible notes in June 1997 along with other various financing activities. The Company is in the process of assessing the impact of year 2000 on its operations and systems, including those of its suppliers and collaborators and other third parties. Management is in the process of formalizing its assessment procedures and developing a plan to address identified issues, if any. To date, the Company has evaluated its financial and accounting systems and concluded that they are not and will not be materially affected by the year 2000. The Company does not yet know the extent, if any, of the impact of the year 2000 on its other systems and equipment or those of third parties with which the Company does business. There can be no assurance that third parties, such as suppliers, clinical research organizations and collabortive parties, are using systems that are year 2000 compliant or will address any year 2000 issues in a timely fashion, or at all. Any year 2000 compliance problems of either the Company, its suppliers, its clinical research organizations, or its collaborative partners could have a material adverse effect on the Company's business, operating results and financial conditions. Future Outlook In addition to historical information, this report contains predictions, estimates and other forward-looking statements that involve a number of risks and uncertainties. These risks and uncertainties include the fact that Shaman is still a relatively young company and has not yet completed a full cycle of development, regulatory approval and commercialization for any of its products. The clinical and regulatory processes through which the Company's products must proceed are complex, uncertain and costly, and no assurance can be given regarding the timing of clinical or regulatory progress or that the Company will be successful in commercializing any of its product candidates. These development processes require substantial amounts of funding, and the Company is dependent on corporate partners and the equity markets to finance such efforts. Where access to funding is difficult, the Company's stockholders may face significant dilution, and the ability of the Company to proceed with its programs and plans may be significantly and adversely affected. Actions and 33 advances by competitors may also significantly affect the Company's prospects, as may the existence of patents held by such competitors or potential competitors. In addition, there can be no assurance that any plants required by the Company will be indefinitely available or that any compounds derived from the plant material will result in protected proprietary rights for the Company. 34 ITEM 8.

Summary of Significant Accounting Policies General Shaman Pharmaceuticals, Inc. ("Shaman" or the "Company") discovers and develops novel pharmaceutical products for major human diseases by isolating active compounds from tropical plants. The Company has three compounds in clinical development: Provir, an oral product for the treatment of AIDS-associated and watery diarrhea; nikkomycin Z, an oral antifungal for the treatment of systemic fungal infections; and SP-134101, an oral product for the treatment of Type II diabetes. Shaman maintains an active Type II diabetes research program which serves as the basis for its collaborations with Lipha s.a., a wholly-owned subsidiary of Merck KGaA, Darmstadt, Germany ("Lipha/Merck"), and with Ono Pharmaceutical Co., Ltd. ("Ono") of Osaka, Japan. Revenue Recognition Revenue recognized under the Company's collaborative research agreements is recorded as earned based upon the performance requirements of the contract. Payments received in advance under these agreements are deferred until earned. Stock-Based Compensation In October 1995, the Financial Accounting Standards Board (FASB) issued SFAS No. 123, "Accounting for Stock-Based Compensation," which encourages, but does not require, companies to record compensation expense for stock-based employee compensation plans at fair value. The Company has elected to follow the disclosure requirements of SFAS No. 123 for the year ended December 31, 1997, 1996 and 1995 and will continue to measure stock-based compensation to employees in accordance with APB Opinion No. 25, "Accounting for Stock Issued to Employees." Accordingly, the disclosure requirements will have no effect on the Company's financial position or results of operations. Note 7 contains a summary of the pro forma effects to reported net loss and net loss per share for 1997, 1996 and 1995 as if the Company had elected to recognize compensation expense based on the fair value of options granted as described by SFAS 123. The Company grants stock options to employees and directors for a fixed number of shares with an exercise price equal to the fair market value of shares at the date of grant. The Company accounts for stock option grants to employees and directors in accordance with APB Opinion No. 25, Accounting for Stock Issued to Employees and, accordingly, recognizes no compensation expense for the stock option grants to employees and directors. Per Share Data In February 1997, the Financial Accounting Standards Board issued Statement No. 128, Earnings per Share, which the Company adopted in the period ended December 31, 1997. Under the new requirements for calculating basic earnings per share, the dilutive effect of stock options and other common stock equivalents is excluded. The impact of Statement 128 results in no change to the Company's net loss per share, as stock options and other common stock equivalents have been excluded from the current computation as they are antidilutive. Net loss per share is computed using the weighted average number of shares of common stock outstanding. 40 Cash, Cash Equivalents, Investments and Concentration of Credit Risk The Company considers all highly liquid investments with remaining maturities of three months or less at time of purchase to be cash equivalents. Investments with maturities of less than one year from the balance sheet date and with original maturities greater than 90 days are considered short-term investments. Investments with maturities greater than one year from the balance sheet date are considered long-term investments. Investments consist primarily of commercial paper, investments in government securities, corporate bonds and asset-backed securities. These investments typically bear minimal risk. This diversification of risk is consistent with the Company's policy to maintain high liquidity and ensure safety of principal. The Company maintains its cash, cash equivalents and investments in accounts with several United States banks and brokerage houses. Management determines the appropriate classification of debt securities at the time of purchase and re-evaluates such determination as of each balance sheet date. As of December 31, 1997 and 1996, the Company has classified its entire investment portfolio as available-for-sale. Available-for-sale securities are carried at fair value, with the unrealized gains and losses, net of tax, included in stockholders' equity. The amortized cost of debt securities in this category is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization is included in interest income. Realized gains and losses and declines in value judged to be other-than-temporary on available-for-sale securities are included in interest income or expense. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available-for-sale are included in interest income. Property and Equipment Property and equipment are stated at cost. Depreciation of equipment and furniture is provided on a straight-line basis over the estimated useful lives of the respective assets, which range from three to five years. Equipment held under capital leases is amortized using the straight-line method over the shorter of the lease term or estimated useful life of the asset. Leasehold improvements are amortized on a straight-line basis over the remaining life of the lease. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Reclassification Certain prior year amounts have been reclassified to conform to the current year's presentation. 2. Collaborative Relationships In September 1996, the Company entered into a five-year collaborative agreement with Lipha/Merck to jointly develop Shaman's antihyperglycemic drugs. Upon signing the collaboration, the Company received an annual research fee of $1.5 million which was amortized to revenue over twelve months as work was performed. The Company also received approximately $3 million for 388,918 shares of common stock priced at $7.71 per share, representing a 20% premium to the weighted average price of the Company's stock at the time of purchase. In exchange for development and marketing rights in all countries except Japan, South Korea, and Taiwan (which are covered under an earlier agreement between Shaman and Ono, Lipha/Merck will provide up to $9.0 million in research 41 payments and up to $10.5 million in equity investments priced at a 20% premium to a multi-day volume weighted average price of the Company's common stock at the time of purchase. The agreement also provides for additional preclinical and clinical milestone payments to the Company in excess of $10.0 million per compound for each antihyperglycemic drug developed and commercialized. Lipha/Merck will bear all pre-clinical, clinical, regulatory and other development expenses associated with the compounds selected under the agreement. In addition, as products are commercialized, Shaman will receive royalties on all product sales outside the United States and up to 50% of the profits (if the company exercises its co-promotion rights) or royalties on all product sales in the United States. Certain of the milestone payments will be credited against future royalty payments, if any, due to the Company from sales of products developed pursuant to the agreement. For the year ended December 31, 1997,Shaman recognized $1.5 million in revenue from the Lipha/Merck collaboration. Shaman also received $1.5 million for 200,787 shares of Common Stock priced at $7.47 per share, representing a 20% premium to the weighted average price of the Company's stock at the time of purchase. Revenues from Lipha/Merck accounted for 43% and 12% of total revenues earned in 1997 and 1996, respectively. In May 1995, the Company entered into a collaborative agreement with Ono providing for, among other things, three years of funding for the research and development of compounds for the treatment of Type II diabetes. Under the agreement, Shaman will screen 100 diabetes-specific plants per year in vivo, isolate and identify active compounds, and participate in any medicinal chemistry modification. In turn, Ono will provide Shaman with access to Ono's preclinical and clinical development capabilities through proprietary in vitro assays and medicinal chemistry effort. Ono's development and commercialization rights are for the countries of Japan, South Korea and Taiwan. Under the terms of the agreement, Ono will provide up to $7.0 million in collaborative research funding and will pay preclinical and clinical milestone payments of $4.0 million per compound for each antidiabetic drug that is commercialized. Of the $3.0 million received on signing the agreement, $1.0 million was an access and license fee recognized as revenue in 1995, and the remaining $2.0 million was the annual research and development funding recognized as revenue over the subsequent year. Shaman received an additional $1.0 million payment (beyond the $7.0 million commitment) in December 1996 for enhanced access rights to these compounds. For the year ended December 31, 1997, Shaman recognized $2.0 million in revenue from the Ono collaboration. Revenues from Ono accounted for 57% and 88% of total revenues earned in 1997 and 1996, respectively. Costs associated with revenue from these collaborations totaled $11.4 million and $11.6 million for the year ended December 31, 1997 and 1996, respectively, and are included in research and development expenses in the accompanying financial statements. 3.

The estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methodologies. However, judgment is required in interpreting market data to develop the estimates of fair value. Fair Value of Long-Term Obligations The fair values of the Company's long-term obligations are estimated using discounted cash flow analyses based on the Company's current incremental borrowing rate for similar types of borrowing arrangements. The carrying amounts and fair values of long-term obligations consisted of the following at December 31, 1997: Carrying Value Fair Value -------------- ---------- Leasehold improvements financings $2,093,435 $2,010,938 Equipment borrowings $ 401,555 $ 403,194 Secured Loan $4,190,105 $4,330,073 The carrying value of the Company's term loan approximates its fair value because the interest rates on the note takedowns are periodically reset. 43 4. Long-Term Obligations Long-term obligations consist of secured and unsecured term loans, senior convertible notes, secured borrowings used to acquire property and equipment, capital lease arrangements and a leasehold improvement financing obligation. In October 1995, the Company closed a $2.5 million unsecured term loan to finance capital asset acquisitions and potential facilities expansion. The Company failed to achieve certain financing and collaborative objectives by May 15, 1996 which resulted in an acceleration of principal. The acceleration provisions required that principal amortization be shortened from 30 months to 24 months, with the first monthly payment due May 15, 1996. The unsecured term loan was paid off in May 1997. Interest on each advance was charged at the London Interbank Offered Rate ("LIBOR") plus 1.5% or prime plus 0.5%. The interest rate on the loan was approximately 7.14% at May 1997 and 7.13% at December 31, 1996. In May 1997, the Company obtained a $5.0 million term loan to payoff pre-existing debt, finance capital asset acquisitions and finance continued research and clinical development. The loan is payable in thirty-six equal monthly installments and the interest rate is 14.58%. The lender was granted warrants to purchase 200,000 shares of the Company's Common Stock at $6.25 per share, which are exercisable over a ten year period. In June 1997, the Company privately issued $10.4 million of senior convertible notes (The "1997 Private Placement"). The notes mature in August 2000 and bear interest at a rate of 5.5% per annum. Interest on the notes may be paid in Common Stock or cash at the Company's option. Initially, the notes are convertible into Common Stock of the Company at 100% of the low trading price during a designated time period prior to conversion provided that the conversion price will not be less than $5.50 per share. Starting in November 1997, the notes are convertible into Common Stock of the Company at a 10% discount from the low trading price during a designated time period prior to the conversion, with a floor of $5.50 through March 31, 1998, pursuant to a November 1997 understanding with the note holders to revise the terms of the note. In connection with this understanding, the Company issued to the note holders three-year warrrants to purchase an aggregate of 137,500 shares of common stock at an exercise price of $7.50 per share. In November 1997, a principal amount of $220,666 was converted into 55,102 shares of the Company's Common Stock. Of the notes issued, $400,000 were issued to the placement agent as part of the placement fee. The Company paid the placement agent an additional $300,000 in cash. The placement fees and other offering costs have been capitalized in other assets as deferred issuance costs and are being amortized to interest expense ove the life of the notes. The net proceeds totaled approximately $9.5 million after the placement agent's fees and other offering expenses. The SEC has promulgated requirements for charges to be recognized by companies which issue certian convertible notes that provide for a guaranteed discount feature. In connection with the issuance of the notes, the Company recognized a non-cash charge in the amount of $3,692,000 in the third quarter ended September 30, 1997. This amount was calculated as required by the SEC. Equipment borrowings totaled $401,555 and $1,183,335 at December 31, 1997 and 1996, respectively. The borrowings bear interest at rates ranging from 10.7% to 12.75% at December 31, 1997 and 1996, respectively, are secured by the equipment acquired, and are payable in monthly installments ranging from $10,000 to $156,000 through December 1998. 44 The Company has also acquired certain equipment and furniture pursuant to capital lease arrangements. The gross amount of equipment and furniture and the related accumulated amortization recorded under capital leases included in property and equipment are as follows: At December 31, 1997 1996 ---- ---- Equipment and furniture $ 1,890,164 $ 1,461,141 Less accumulated amortization (1,354,475) (1,194,475) ----------- ----------- $ 535,689 $ 266,666 =========== =========== Amortization of assets acquired under capital leases is included with depreciation and amortization expense. In connection with the facility lease described in Note 5, the Company entered an agreement with the former tenant of the facility to acquire approximately $1.5 million of tenant improvements by making annual payments to the former tenant, including accrued interest, of $540,000 in 1998 through 2002. At December 31, 1997, future payments on long-term obligations are as follows: Senior Leasehold Convertible Secured Equipment Capital Improvement Notes Loan Borrowings Leases Financing Total ---------- --------- --------- --------- ----------- ---------- 1998 $ -- $1,558,076 $401,555 $128,382 $540,000 $2,628,013 1999 -- 1,801,058 -- 128,382 540,000 2,469,440 2000 10,179,334 830,971 -- 128,382 540,000 11,678,687 2001 -- -- -- 128,382 540,000 668,382 2002 -- -- -- -- 540,000 540,000 ---------- --------- --------- --------- ----------- ---------- Total minimum payments 10,179,334 4,190,105 401,555 513,528 2,700,000 17,984,522 Less amount representing interest (at rates ranging from 10.7% to 14.6% -- -- -- (84,506) (606,565) (691,071) ---------- --------- --------- --------- ---------- ---------- 10,179,334 4,190,105 401,555 429,022 2,093,435 17,293,451 Less current installments -- (1,558,076) (401,555) (92,507) (540,000) (2,592,138) ---------- --------- --------- --------- ---------- ---------- Long-term obligations, excluding current install- ments $10,179,334 $2,632,029 $ -- $336,515 $1,553,435 $14,701,313 =========== =========== ========= ======== =========== ========== 5. Commitments and Contingencies In January 1993, the Company entered a noncancelable lease for a new research and office facility in South San Francisco, California. The lease, as amended in April 1994, provides for future lease payments totaling approximately $7.7 million through 2003 and options to renew for a total of ten years. The Company is required to pay operating costs, including property taxes, utilities, insurance and maintenance. At December 31, 1997, the minimum noncancelable future rental payments under the Company's operating leases are: 1998 $1,187,000 1999 1,292,000 2000 1,497,000 2001 1,497,000 2002 1,497,000 Thereafter 762,000 45 Rent expense for each of the three years ended December 31, 1997, 1996 and 1995 was approximately $1,154,000, $1,348,000, and $1,004,000, respectively. The Company is involved in litigation, arbitration and disputes which are normal to its business. Management believes losses that might eventually be sustained from such matters, if any, would not be material to future years' financial position or results of operations. Further, product liability claims may be asserted in the future relative to events not known to management at the present time. The Company has insurance coverage which management believes is adequate to protect against such product liability losses as could materially affect the Company's financial position. 6. Contractual Agreements The Company has entered into license, clinical trial and supply agreements with universities, research organizations and commercial companies. Certain of these agreements require payments of royalties on future sales of resulting products and may subject the Company to minimum annual payments to its contract partners. In addition, the Company signed an agreement in 1995 which could result in the payment of milestone installments if certain development objectives are achieved. To date, payments under these agreements have not been significant and, at December 31, 1997, related noncancelable commitments are immaterial. 7. Stockholders' Equity Preferred Stock The Company is authorized to issue 1,000,000 shares of preferred stock (400,000 shares of which are issued and outstanding). The Company's Board of Directors may set the rights and privileges of any preferred stock issued. In July 1996, the Company closed a private placement pursuant to Regulation S under the Securities Act of 1933, as amended, in which it received gross proceeds of $3.3 million for 400,000 shares of Series A convertible preferred stock ("preferred stock") and a six-year warrant to purchase 550,000 shares of the Company's common stock at an exercise price of $10.184 per share. The Preferred Stock does not carry a dividend obligation and will convert into common stock no later than July 23, 1999 at a price per share between $6.00 and $8.147, depending on the market value of the Company's common stock during the period prior to conversion. Holders of preferred shares are entitled to a liquidation preference of $8.147 per share and have voting rights equivalent to the number of common shares into which their preferred shares could then be converted. In addition to the sale of Preferred Stock and warrant, the Company has the right, from time to time during the period beginning January 1997 and ending July 2000, to sell up to 1,200,000 additional shares of common stock to the investor at a formula price of 100% or 101% of a multi-day average of the Company's common stock price at the time of sale. If the Company exercises this right, the investor has the option to increase the shares purchased by up to an aggregate of 527,500 shares. 46 Common Stock In December 1992, the Company adopted the 1992 Stock Option Plan (the Plan) as the successor plan to the Company's 1990 Stock Option Plan. The Plan will terminate on the earlier of December 31, 2002 or the date on which all shares available for issuance under the Plan have been issued or canceled. The Plan provides for two separate components: the Discretionary Option Grant Program and the Automatic Option Grant Program. Under the Discretionary Option Grant Program, options granted may either be incentive options or non-statutory options. Incentive options may be granted to employees at a price not less than the fair market value of the Company's common stock on the grant date. Non-statutory options may be granted at a price determined by the plan administrator. Each option granted is exercisable as determined by the plan administrator, with a term not to exceed ten years. The Plan also allows for the granting of options with repurchase rights and stock appreciation rights at the discretion of the plan administrator. Under the Automatic Option Grant Program, each individual who becomes a non-employee board member on or after the effective date of the Plan is automatically granted a non-statutory stock option to purchase 20,000 shares of common stock. Further, each non-employee board member who has served as a member for at least six months prior to the annual stockholders' meeting is automatically granted an annual non-statutory stock option to purchase not more than 7,500 nor less than 5,000 shares of common stock, depending on a calculation based on the average selling price of the common stock. The exercise price of each option granted is the fair value of the common stock on the date of grant. These options have a ten-year term and vest over 24 months. Both programs provide for automatic acceleration of the exercise period in the event of certain corporate transactions, including a merger, asset sale or change in control of the Company. The Plan was amended in 1997 to increase the shares authorized for issuance by additional 700,000 shares. The 1990 Stock Option Plan provided for the granting of incentive and non-statutory stock options. Both types of options were immediately exercisable and expire ten years from the date of grant. Vesting of optioned shares was determined by the board of directors and generally occurred over a two- to four-year period from the date of grant. At December 31, 1997, all options to purchase common stock issued under this plan were vested. A summary of stock option activity is as follows: Options Outstanding --------------------------------------------------- Weighted Weighted Average Average Number Price Per Exercise Fair Value of Shares Share Price at Grant Date ------------- ---------- ---------- ------------- Balance at December 31, 1995 1,809,065 $ .06-13.25 $ 4.40 Granted at fair value 847,928 5.88- 8.13 6.75 $ 3.85 Exercised (273,978) .06- 7.86 1.61 Forfeited (281,039) .24-13.25 6.12 ---------- ---------- ----- ----- Balance at December 31, 1996 2,101,976 .06-13.25 5.48 Granted at fair value 951,400 4.13- 6.81 5.41 $ 3.46 Exercised (19,472) .24- 5.88 3.29 Forfeited (242,299) 3.50-13.25 6.40 ----------- ---------- ----- ----- Balance at December 31, 1997 2,791,605 $ .06-13.25 $ 5.40 =========== =========== ====== ====== At December 31, 1997, 1,310,036 shares under options were exercisable at a weighted average exercise price of $5.25 per share (968,235 shares at $5.10 per share at December 31, 1996). 47 The following table summarizes information regarding stock options outstanding at December 31, 1997: Weighted Shares under Options Average Exercisable at Option Shares Contractual Weighted December 31, 1997 Range of Outstanding at Remaining Average --------------------- Exercise December 31, Life Exercise Weighted Average Prices 1997 (Years) Price Number Exercise Price --------- -------------- ------------- ---------- ------- -------------- $0.06-$ 3.63 684,820 6.20 $ 2.71 517,558 $ 2.46 4.13- 5.25 605,394 8.53 5.07 127,627 5.20 5.38- 6.06 735,288 8.89 5.68 243,280 5.59 6.38- 7.50 571,028 8.01 6.88 235,492 6.91 7.86- 13.25 195,075 5.86 10.41 186,079 10.52 - ------------ ----------- ----- ------ -------- ------- $0.06-$13.25 2,791,605 7.76 $ 5.39 1,310,036 $ 5.25 ============ ========= ===== ====== ========= ====== For certain options issued during the years ended December 31, 1993 and 1994, the Company recorded deferred compensation for the difference between the exercise price and the fair market value of the Company's common stock at the date of grant. For certain additional options issued during the years ended December 31, 1996 and 1997 to non-employees, the Company recorded deferred compensation expense for the fair value of the options at the date of grant. Deferred compensation is amortized to expense on a straight-line basis over the vesting period of the options. Pro Forma Information The Company has elected to follow Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25") and related interpretations in accounting for its employee stock options because, as discussed below, the alternative fair value accounting provided for under FASB No. 123, "Accounting for Stock-Based Compensation," requires use of option valuation models that were not developed for use in valuing employee stock options. Under APB 25, 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. Pro forma information regarding net loss and net loss per share is required by SFAS 123, and has been determined as if the Company had accounted for its employee stock options granted subsequent to December 31, 1994 under the fair value method of SFAS 123. The fair value for these options was estimated at the date of grant using the Black-Scholes option pricing model. The following are the weighted-average assumptions for 1997, 1996 and 1995 respectively: risk-free interest rates of 6.27%, 5.73%, and 6.94%; no dividends paid; volatility factors of the expected market price of the Company's common stock of .75 and a weighted-average expected life of the options of 5.0, 3.85, and 3.91 years. The effects of applying FAS 123 for recognizing compensation expense and providing pro forma disclosures in 1997 and 1996 are not likely to be representative of the effects on reported net income in future 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 48 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 the Company's employee stock options. For purposes of pro forma disclosures, the estimated fair value of the options is amortized to pro-forma net loss over the options' vesting periods. The Company's pro forma information follows (in thousands except for net loss per share information): 1997 1996 1995 ---- ---- ---- Net loss Historical $ (29,289) $ (18,790) $ (18,004) Pro forma $ (31,101) $ (20,280) $ (18,731) Net loss per share Historical $ (1.72) $ (1.39) $ (1.37) Pro forma $ (1.83) $ (1.50) $ (1.42) Reserved Shares At December 31, 1997, 4,560,284 shares of common stock were reserved for conversion of outstanding preferred stock and for issuance upon exercise of outstanding options, warrants and options available for future grant. Warrants In connection with obtaining long term debt financing in May 1997, the Company agreed to issue warrants to purchase a total of 200,000 shares of common stock at an exercise price of $7.50 per share (see Note 4). These warrants were determined to have a total value of $648,000 based on the Black Scholes option pricing model. Such value has been recognized as a reduction to the related debt and is being amortized to interest expense over the term of such debt. In connection with an amendment to the conversion terms of senior convertible notes in November 1997, the Company issued warrants to purchase a total of 137,500 shares of common stock (see Note 4). These warrants were determined to have a total value of $309,000 based on the Black Scholes option pricing model. Such value has been recognized as a reduction to the related convertible notes and is being amortized to interest expense over the extended conversion term. At December 31, 1997, warrants to purchase a total of 979,205 shares of common stock were outstanding, with exercise prices ranging from $2.40 to $10.83 per share. These warrants, which expire in 1998 through 2007, were issued to creditors in connection with certain lease financing arrangements and preferred stock financing arrangements. 8. Taxes As of December 31, 1997, the Company had federal net operating loss carryforwards of approximately $102 million. The net operating loss and credit carryforwards will expire at various dates beginning in 2004 through 2012, if not sooner utilized. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and the amounts used for income tax purposes. 49 Significant components of the Company's deferred tax assets and liabilities for federal and state income taxes as of December 31, 1997, 1996 and 1995 are as follows: Deferred tax assets: 1997 1996 1995 --------- --------- -------- Net operating loss carryforwards $35,200,000 $26,600,000 $20,600,000 Research credits (expiring in 2004 - 2012) 2,800,000 2,300,000 1,900,000 Capitalized research and development costs 4,700,000 3,700,000 2,900,000 Other 400,000 400,000 100,000 ------------ ----------- ----------- Total deferred tax assets 43,100,000 33,000,000 25,500,000 Valuation allowance for deferred tax assets (43,100,000) (33,000,000) (25,500,000) ------------ ----------- ----------- Net deferred tax asset $ -- $ -- $ -- ============ ============ =========== The net valuation allowance increased by $6.7 million during the year ended December 31, 1995. Utilization of the net operating losses and credits may be subject to a substantial annual limitation due to the "change in ownership" provisions of the Internal Revenue Code of 1986 and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization. ITEM 9.

Palo Alto, California March 2, 1998 ERNST & YOUNG LLP 58 EXHIBIT 10.64 MASTER LEASE AGREEMENT, WITH RELATED SCHEDULES BETWEEN TRANSAMERICA BUSINESS CREDIT CORPORATION AND SHAMAN PHARMACEUTICALS MASTER LEASE AGREEMENT Lessor: TRANSAMERICA BUSINESS CREDIT CORPORATION Riverway II West Office Tower West Higgins Rosemont, Illinois 60018 Lessee: SHAMAN PHARMACEUTICALS, INC. 213 East Grand Avenue South San Francisco, California 94080-4812 The lessor pursuant to this Master Lease Agreement ("Agreement") dated as of September 15, 1997, is Transamerica Business Credit Corporation ("Lessor"). All equipment, together with all present and future additions, parts, accessories, attachments, substitutions, repairs, improvements, and replacements thereof or thereto, which are the subject of a Lease (as defined in the next sentence) shall be referred to as "Equipment." Simultaneous with the execution and delivery of this Agreement, the parties are entering into one or more Lease Schedules (each, a "Schedule") which refer to and incorporate by reference this Agreement, each of which constitutes a lease (each, a "Lease") for the Equipment specified therein. Additional details pertaining to each Lease are specified in the applicable Schedule. Each Schedule that the parties hereafter enter into shall constitute a Lease. Lessor has no obligation to enter into any additional leases with, or extend any future financing to, Lessee. 1. LEASE. Subject to and upon all of the terms and conditions of this Agreement and each Schedule, Lessor hereby agrees to lease to Lessee and Lessee hereby agrees to lease from Lessor the Equipment for the Term (as defined in Paragraph 2 below) thereof. The timing and financial scope of Lessor's obligation to enter into Leases hereunder are limited as set forth in the Commitment Letter executed by Lessor and Lessee, dated as of August 26, 1997 and attached hereto as Exhibit A (the "Commitment Letter"). 2. TERM. Each Lease shall be effective and the term of each Lease ("Term") shall commence on the commencement date specified in the applicable Schedule and, unless sooner terminated (as hereinafter provided), shall expire at the end of the term specified in such Schedule; provided, however, that obligations due to be performed by Lessee during the Term shall continue until they have been performed in full. Schedules will only be executed after the delivery of the Equipment to Lessee or upon completion of deliveries of items of such Equipment with aggregate cost of not less than $50,000. 3. RENT. Lessee shall pay as rent to Lessor, for use of the Equipment during the Term or Renewal Term (as defined in Paragraph 8), rental payments equal to the sum of all rental payments including, without limitation, security deposits, advance rents, and interim rents payable in the amounts and on the dates specified in the applicable Schedule ("Rent"). If any Rent or other amount payable by Lessee is not paid within five days after the day on which it becomes payable, Lessee will pay on demand, as a late charge, an amount equal to 5% of such unpaid Rent or other amount but only to the extent permitted by applicable law. All payments provided for herein shall be payable to Lessor at its address specified above, or at any other place designated by Lessor. 4. LEASE NOT CANCELABLE; LESSEE'S OBLIGATIONS ABSOLUTE. No Lease may be canceled or terminated except as expressly provided herein. Lessee's obligation to pay all Rent due or to become due hereunder shall be absolute and unconditional and shall not be subject to any delay, reduction, set-off, defense, counterclaim, or recoupment for any reason whatsoever, including any failure of the Equipment or any representations by the manufacturer or the vendor thereof. If the Equipment is unsatisfactory for any reason, Lessee shall make any claim solely against the manufacturer or the vendor thereof and shall, nevertheless, pay Lessor all 1 Rent payable hereunder. 5. SELECTION AND USE OF EQUIPMENT. Lessee agrees that it shall be responsible for the selection and use of, and results obtained from, the Equipment and any other associated equipment or services. 6. WARRANTIES. LESSOR MAKES NO REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS TO ANY MATTER WHATSOEVER, INCLUDING, WITHOUT LIMITATION, THE DESIGN OR CONDITION OF THE EQUIPMENT OR ITS MERCHANTABILITY, SUITABILITY, QUALITY, OR FITNESS FOR A PARTICULAR PURPOSE, AND HEREBY DISCLAIMS ANY SUCH WARRANTY. LESSEE SPECIFICALLY WAIVES ALL RIGHTS TO MAKE A CLAIM AGAINST LESSOR FOR BREACH OF ANY WARRANTY WHATSOEVER. LESSEE LEASES THE EQUIPMENT "AS IS." IN NO EVENT SHALL LESSOR HAVE ANY LIABILITY, NOR SHALL LESSEE HAVE ANY REMEDY AGAINST LESSOR, FOR ANY LIABILITY, CLAIM, LOSS, DAMAGE, OR EXPENSE CAUSED DIRECTLY OR INDIRECTLY BY THE EQUIPMENT OR ANY DEFICIENCY OR DEFECT THEREOF OR THE OPERATION, MAINTENANCE, OR REPAIR THEREOF OR ANY CONSEQUENTIAL DAMAGES AS THAT TERM IS USED IN SECTION 2-719(3) OF THE MODEL UNIFORM COMMERCIAL CODE, AS AMENDED FROM TIME TO TIME ("UCC"). Lessor grants to Lessee, for the sole purpose of prosecuting a claim, the benefits of any and all warranties made available by the manufacturer or the vendor of the Equipment to the extent assignable. 7. DELIVERY. Lessor hereby appoints Lessee as Lessor's agent for the sole and limited purpose of accepting delivery of the Equipment from each vendor thereof. Lessee shall pay any and all delivery and installation charges. Lessor shall not be liable to Lessee for any delay in, or failure of, delivery of the Equipment. 8. RENEWAL. So long as no Event of Default or event which, with the giving of notice, the passage of time, or both, would constitute an Event of Default, shall have occurred and be continuing, or the Lessee shall not have exercised its purchase option under Paragraph 9 hereof, each Lease will automatically renew for a term specified in the applicable Schedule (the "Renewal Term") on the terms and conditions of this Agreement or as set forth in such Schedule; provided, however, that Obligations due to be performed by the Lessee during the Renewal Term shall continue until they have been performed in full. 9. PURCHASE OPTION. So long as no Event of Default or event which, with the giving of notice, the passage of time, or both, would constitute an Event of Default, shall have occurred and be continuing, Lessee may, upon written notice to Lessor received at least one hundred eighty days before the expiration of a Term, purchase all, but not less than all, the Equipment covered by the applicable Lease on the date specified therefor in the applicable Schedule ("Purchase Date"). The purchase price for such Equipment shall be its fair market value as set forth in the applicable Schedule determined on an "In-place, In-use" basis, as mutually agreed by Lessor and Lessee, or, if they cannot agree, as determined by an independent appraiser selected by Lessor and approved by Lessee, which approval will not be unreasonably delayed or withheld. Lessee shall pay the cost of any such appraisal. So long as no Event of Default or event which, with the giving of notice, the passage of time, or both, would constitute an Event of Default shall have occurred and be continuing, Lessee may, upon written notice to Lessor received at least one hundred eighty days prior to the expiration of the Renewal Term, purchase all, but not less than all, the Equipment covered by the applicable Schedule by the last date of the Renewal Term (the "Alternative Purchase Date") at a purchase price equal to its then fair market value on an "In-place, In-use" basis. On the Purchase Date or the Alternative Purchase Date, as the case may be, for any Equipment, Lessee shall pay to Lessor the purchase price, together with all sales and other taxes applicable to the transfer of the Equipment and any other amount payable and arising hereunder, in immediately available funds, whereupon Lessor shall transfer to Lessee, without recourse or warranty of any kind, express or implied, all of Lessor's right, title, and interest in and to such Equipment on an "As Is, Where Is" basis. 10. OWNERSHIP; INSPECTION; MARKING; FINANCING STATEMENTS. Lessee shall affix to the Equipment any labels supplied by Lessor indicating ownership of such Equipment. The Equipment is and shall be the sole property of Lessor. Lessee shall have no right, title, or interest therein, except as lessee under a Lease. The Equipment is and shall at all times be and remain personal property and shall not become a 2 fixture. Lessee shall obtain and record such instruments and take such steps as may be necessary to prevent any person from acquiring any rights in the Equipment by reason of the Equipment being claimed or deemed to be real property. Upon request by Lessor, Lessee shall obtain and deliver to Lessor valid and effective waivers, in recordable form, by the owners, landlords, and mortgagees of the real property upon which the Equipment is located or certificates of Lessee that it is the owner of such real property or that such real property is neither leased nor mortgaged. Lessee shall make the Equipment and its maintenance records available for inspection by Lessor at reasonable times and upon reasonable notice. Lessee shall execute and deliver to Lessor for filing any UCC financing statements or similar documents Lessor may reasonably request. 11. EQUIPMENT USE. Lessee agrees that the Equipment will be operated by competent, qualified personnel in connection with Lessee's business for the purpose for which the Equipment was designed and in accordance with applicable operating instructions, laws, and government regulations, and that Lessee shall use all reasonable precautions to prevent loss or damage to the Equipment from fire and other hazards. Lessee shall procure and maintain in effect all orders, licenses, certificates, permits, approvals, and consents required by federal, state, or local laws or by any governmental body, agency, or authority in connection with the delivery, installation, use, and operation of the Equipment. 12. MAINTENANCE. Lessee, at its sole cost and expense, shall keep the Equipment in a suitable environment as specified by the manufacturer's guidelines or the equivalent, shall meet all recertification requirements, and shall maintain the Equipment in its original condition and working order, ordinary wear and tear excepted. At the reasonable request of Lessor, Lessee shall furnish all proof of maintenance. 13. ALTERATION; MODIFICATIONS; PARTS. Lessee may alter or modify the Equipment only with the prior written consent of Lessor. Any alteration shall be removed and the Equipment restored to its normal, unaltered condition at Lessee's expense (without damaging the Equipment's originally intended function or its value) prior to its return to Lessor. Any part installed in connection with warranty or maintenance service or which cannot be removed in accordance with the preceding sentence shall be the property of Lessor. 14. RETURN OF EQUIPMENT. Except for Equipment that has suffered a Casualty Loss (as defined in Paragraph 15 below) and is not required to be repaired pursuant to Paragraph 15 below or Equipment purchased by Lessee pursuant to Paragraph 9 above, upon the expiration of the Renewal Term of a Lease, or upon demand by Lessor pursuant to Paragraph 22 below, Lessee shall contact Lessor for shipping instructions and, at Lessee's own risk, immediately return the Equipment, freight prepaid, to a location in the continental United States specified by Lessor. At the time of such return to Lessor, the Equipment shall (i) be in the operating order, repair, and condition as required by or specified in the original specifications and warranties of each manufacturer and vendor thereof, ordinary wear and tear excepted, (ii) meet all recertification requirements, and (iii) be capable of being promptly assembled and operated by a third party purchaser or third party lessee without further repair, replacement, alterations, or improvements, and in accordance and compliance with any and all statutes, laws, ordinances, rules, and regulations of any governmental authority or any political subdivision thereof applicable to the use and operation of the Equipment. Except as otherwise provided under Paragraph 9 hereof, at least one hundred eighty days before the expiration of the Renewal Term, Lessee shall give Lessor notice of its intent to return the Equipment at the end of such Renewal Term. During the one hundred eighty-day period prior to the end of a Term or the Renewal Term, Lessor and its prospective purchasers or lessees shall have, upon not less than two business days' prior notice to Lessee and during normal business hours, or at any time and without prior notice upon the occurrence and continuance of an Event of Default, the right of access to the premises on which the Equipment is located to inspect the Equipment, and Lessee shall cooperate in all other respects with Lessor's remarketing of the Equipment. The provisions of this Paragraph 14 are of the essence of the Lease, and upon application to any court of equity having jurisdiction in the premises, Lessor shall be entitled to a decree against Lessee requiring specific performance of the covenants of Lessee set forth in this Paragraph 14. If Lessee fails to return the Equipment when required, the terms and conditions of the Lease shall continue to be applicable and Lessee shall continue to pay Rent until the Equipment is received by Lessor. 15. CASUALTY INSURANCE; LOSS OR DAMAGE. Lessee will maintain, at its own 3 expense, liability and property damage insurance relating to the Equipment, insuring against such risks as are customarily insured against on the type of equipment leased hereunder by businesses in which Lessee is engaged in such amounts, in such form, and with insurers satisfactory to Lessor; provided, however, that the amount of insurance against damage or loss shall not be less than the greater of (a) the replacement value of the Equipment and (b) the stipulated loss value of the Equipment specified in the applicable Schedule ("Stipulated Loss Value"). Each liability insurance policy shall provide coverage (including, without limitation, personal injury coverage) of not less than $1,000,000 for each occurrence, and shall name Lessor as an additional insured; and each property damage policy shall name Lessor as sole loss payee and all policies shall contain a clause requiring the insurer to give Lessor at least thirty days' prior written notice of any alteration in the terms or cancellation of the policy. Lessee shall furnish to Lessor a copy of each insurance policy (with endorsements) or other evidence satisfactory to Lessor that the required insurance coverage is in effect; provided, however, Lessor shall have no duty to ascertain the existence of or to examine the insurance policies to advise Lessee if the insurance coverage does not comply with the requirements of this Paragraph. If Lessee fails to insure the Equipment as required, Lessor shall have the right but not the obligation to obtain such insurance, and the cost of the insurance shall be for the account of Lessee due as part of the next due Rent. Lessee consents to Lessor's release, upon its failure to obtain appropriate insurance coverage, of any and all information necessary to obtain insurance with respect to the Equipment or Lessor's interest therein. Until the Equipment is returned to and received by Lessor as provided in Paragraph 14 above, Lessee shall bear the entire risk of theft or destruction of, or damage to, the Equipment including, without limitation, any condemnation, seizure, or requisition of title or use ("Casualty Loss"). No Casualty Loss shall relieve Lessee from its obligations to pay Rent except as provided in clause (b) below. When any Casualty Loss occurs, Lessee shall immediately notify Lessor and, at the option of Lessor, shall promptly (a) place such Equipment in good repair and working order; or (b) pay Lessor an amount equal to the Stipulated Loss Value of such Equipment and all other amounts (excluding Rent) payable by Lessee hereunder, together with a late charge on such amounts at a rate per annum equal to the rate imputed in the Rent payments hereunder (as reasonably determined by Lessor) from the date of the Casualty Loss through the date of payment of such amounts, whereupon Lessor shall transfer to Lessee, without recourse or warranty (express or implied), all of Lessor's interest, if any, in and to such Equipment on an "AS IS, WHERE IS" basis. The proceeds of any insurance payable with respect to the Equipment shall be applied, at the option of Lessor, either towards (i) repair of the Equipment or (ii) payment of any of Lessee's obligations hereunder. Lessee hereby appoints Lessor as Lessee's attorney-in-fact to make claim for, receive payment of, and execute and endorse all documents, checks or drafts issued with respect to any Casualty Loss under any insurance policy relating to the Equipment. 16. TAXES. Lessee shall pay when due, and indemnify and hold Lessor harmless from, all sales, use, excise, and other taxes, charges, and fees (including, without limitation, income, franchise, business and occupation, gross receipts, licensing, registration, titling, personal property, stamp and interest equalization taxes, levies, imposts, duties, charges, or withholdings of any nature), and any fines, penalties, or interest thereon, imposed or levied by any governmental body, agency, or tax authority upon or in connection with the Equipment, its purchase, ownership, delivery, leasing, possession, use, or relocation of the Equipment or otherwise in connection with the transactions contemplated by each Lease or the Rent thereunder, excluding taxes on or measured by the net income of Lessor. Upon request, Lessee will provide proof of payment. Unless Lessor elects otherwise, Lessor will pay all property taxes on the Equipment for which Lessee shall reimburse Lessor promptly upon request. Lessee shall timely prepare and file all reports and returns which are required to be made with respect to any obligation of Lessee under this Paragraph 16. Lessee shall, to the extent permitted by law, cause all billings of such fees, taxes, levies, imposts, duties, withholdings, and governmental charges to be made to Lessor in care of Lessee. Upon request, Lessee will provide Lessor with copies of all such billings. 17. LESSOR'S PAYMENT. If Lessee fails to perform its obligations under Paragraph 15 or 16 above, or Paragraph 23 below, Lessor shall have the right to substitute performance, in which case Lessee shall immediately reimburse Lessor therefor. 18. GENERAL INDEMNITY. Each Lease is a net lease.
