PART I Item 1. Business General XOMA Corporation ("XOMA" or the "Company") is a biopharmaceutical company developing products to treat infections, infectious complications of traumatic injury and surgery, and immunologic and inflammatory disorders. The Company's current product development programs include: Neuprex(TM) (rBPI21), a modified recombinantly-derived fragment of human bactericidal/permeability-increasing protein ("BPI") and XOMA's lead BPI-derived product, which is currently in Phase III efficacy clinical trials in two indications and in earlier-stage clinical trials in three additional indications. I-PREX(TM), a proprietary topical formulation of rBPI21 for the treatment of ophthalmic disorders, which is undergoing preclinical testing as a treatment for corneal injuries, including ulcerations and transplants. Mycoprex(TM), a fungicidal peptide compound derived from BPI that is currently in preclinical product development. hu1124 (anti-CD11a), a humanized monoclonal antibody product being developed in collaboration with Genentech, Inc. ("Genentech"), which originally discovered the antibody and characterized it as anti-CD11a. The hu1124 product is in Phase II clinical trials for psoriasis. Other indications are under review. In April 1997, XOMA and Pfizer Inc. ("Pfizer") decided to discontinue the U.S. clinical trial of the Company's E5(R) monoclonal antibody product as a treatment for gram-negative sepsis. In June 1997, the Company announced that Pfizer had decided to end its marketing arrangement for E5(R). Product Areas The following describes XOMA's more significant therapeutic product development and clinical activities: The BPI Product Platform The Company's current programs are primarily focused on developing novel therapeutic products from bactericidal/permeability-increasing protein ("BPI"). BPI is a naturally-occurring human host-defense protein found in white blood cells (neutrophils). BPI kills certain bacteria. It also binds to and neutralizes endotoxins, molecular components of the cell walls of gram-negative bacteria that can trigger severe complications in infected patients. Furthermore, BPI inhibits angiogenesis (growth of new blood vessels) by binding to and neutralizing heparin, a natural protein involved in blood vessel formation. Angiogenesis is an essential component of inflammation and solid tumor growth. BPI was discovered in 1978 by Peter Elsbach, M.D., Professor of Medicine, and Jerrold Weiss, Ph.D., Professor of Microbiology, both at New York University School of Medicine. XOMA has collaborated with NYU since 1991 to extend and apply BPI-related research to the commercial development of pharmaceutical products. Since March 1993, the U.S. Patent and Trademark Office ("Patent Office") has issued four patents and a Notice of Allowance relating to BPI to NYU, and the Company is the exclusive licensee of these 2 patents and the Notice of Allowance. See "Patents and Trade Secrets". XOMA has an agreement with New York University ("NYU") relating to its rBPI products. See "Research and License Agreements". XOMA has adopted the BPI molecule as a platform for developing multiple pharmaceutical products. In 1991 XOMA scientists developed a modified recombinant fragment of the BPI molecule, called rBPI21, which is potent and stable and can be manufactured at commercially viable yields. This modified fragment is the basis for the Company's Neuprex(TM) and I-PREX(TM) products. In 1994 XOMA scientists discovered three functional domains in the BPI molecule with pharmacologically-desirable activities. Based on this discovery, XOMA is developing peptides from these domains into additional therapeutic products, including the Mycoprex(TM) antifungal peptide product. Neuprex(TM) In December 1992, XOMA submitted an investigational new drug application ("IND") to the U.S. Food and Drug Administration ("FDA") to begin Phase I human testing of Neuprex(TM). In March 1993, the Company began Phase I human safety and pharmocokinetic testing under the IND. Beginning in 1995, the Company initiated five clinical efficacy studies evaluating Neuprex(TM) as a treatment for primary infections and major complications of infectious diseases, traumatic injury and surgery. These indications are: Severe pediatric meningococcemia: a deadly bacterial infection that usually afflicts children. In August 1996, FDA's Center for Biologics Evaluation and Research ("CBER") granted XOMA a Subpart E designation for Neuprex(TM) for the treatment of severe pediatric meningococcemia following favorable results in an open label Phase I/ II pilot study. This designation is intended to expedite the development of treatments for life-threatening illnesses. The Company subsequently began a Phase III pivotal trial for the indication in October 1996 in the United States and Canada. In the first quarter of 1997, XOMA added a trial site in the United Kingdom to increase patient accrual. The company enrolled additional U.K. sites in late 1997 and early 1998. Hemorrhage due to trauma: accidents or injuries that cause acute blood loss may trigger serious complications in up to 40% of patients who survive the initial trauma and surgery. These patients may be infected by bacteria and their endotoxins translocated from the gastrointestinal tract into the bloodstream. A placebo-controlled, double-blinded Phase II study in 401 patients began in June 1995 and was completed in October 1996. A follow-on single-blinded Phase II pharmacokinetics study explored alternative dosing regimens in 169 patients. Based on data from the Phase II studies, XOMA initiated in the fourth quarter of 1997 a Phase III pivotal trial, designed to enroll 1650 patients in 40 centers, testing Neuprex(TM) to prevent serious pulmonary complications in trauma patients. Partial hepatectomy: surgical removal of part of the liver, usually to remove an isolated tumor temporarily impairs liver function. Since the liver normally clears bacteria and their endotoxins, these patients are at risk for infectious complications. The double-blinded, placebo-controlled Phase II study in 35 patients began in mid-1995 and was concluded at the end of 1997. Review and analysis of results is in progress. Severe intra-abdominal infections: in 1996, the Company began a Phase I/II open-label dose-ranging study testing Neuprex(TM) with conventional antibiotics to treat patients with serious abdominal infections that required surgery. Cystic fibrosis (CF): in the third quarter of 1997, XOMA initiated a program to test Neuprex(TM) in CF patients whose genetic disorder predisposes them to recurring bacterial lung infections (exacerbations). Over repeated antibiotic treatments, the infecting bacteria often become resistant to antibiotic treatment. A natural history study in the second half of 1997 tested rBPI21, alone and in combina- 3 tion with antibiotics, against bacterial cultures collected from CF patients. A Phase I safety and pharmacokinetics study began in the fourth quarter of 1997. There can be no assurance that any of the continuing trials will yield data that will result in licensure of Neuprex(TM) in the U.S. I-PREX(TM) XOMA has developed a proprietary topical formulation of rBPI21 for the treatment of ophthalmic infections. Although standard antibiotics fight bacterial infections, they do not inhibit the growth of new blood vessels in the cornea that may be associated with these infections. This neovascularization can lead to scarring and permanently impaired vision. In preclinical testing, the I-PREX(TM) product has shown both anti-ineffective and anti-angiogenic (inhibition of blood vessel growth) properties in the treatment of corneal injury and associated infection. The use of I-PREX(TM) to treat corneal injuries, including ulcers and other corneal diseases, could eliminate the need for current anti-inflammatory therapies, such as corticosteroids, which have undesirable side effects. Mycoprex(TM) XOMA scientists discovered that certain peptide sequences derived from BPI display potent fungicidal activity. Further research demonstrated that many of these compounds not only kill strains of Candida, the most common fungi to cause systemic illness, but also show activity against other strains of fungi, including those resistant to the currently available drugs. Based on these findings, the Company is conducting a program to develop compounds with a broad spectrum of fungicidal activity and a better safety profile than currently-available fungicidals. LBP Assay In the first quarter of 1997, the Company granted to BioSite Diagnostics Incorporated of San Diego, California an exclusive U.S. license to make, use and sell certain non-automated, point-of-care diagnostic and prognostic products for measuring Lipopolysaccharide Binding Protein ("LBP") to detect bacterial endotoxin exposure in patients with endotoxemia or sepsis. A non-exclusive license was granted to SRL, Inc., a Japanese company, to make, use and sell certain automated diagnostic and prognostic products for centralized laboratory use in Japan. hu1124 (anti-CD11a) Monoclonal Antibody Product In April 1996, XOMA and Genentech entered into an agreement to co-develop Genentech's anti-CD11a humanized monoclonal antibody product (hu1124). In late 1996, the Company started a Phase I trial in moderate to severe psoriasis patients. In the second quarter of 1997, in response to findings that hu1124 was active at smaller doses, XOMA started additional Phase I studies at lower doses. XOMA announced a Phase II efficacy study in Canadian psoriasis patients in February 1998. Other indications are under review by XOMA and Genentech. Additional Product Areas XOMA continues to seek opportunities to realize value from products and technologies outside its core research efforts, including immunoconjugates, immunofusions, mammalian and microbial cell expression technologies, osteoinductive proteins for bone repair, and non-cariogenic proteins for low-calorie flavor enhancement. Various licenses and sublicenses have been entered into in these areas. Discussions are ongoing with other entities that have expressed interest in these products and technologies. No assurance can be given that any agreement or agreements will be reached as a result of the ongoing discussions. 4 In 1996, XOMA received a $2.2 million payment related to the sale of its T-cell receptor ("TCR") technology to Connective Therapeutics, Inc., now called Connetics Corporation ("Connetics"). Connetics is using the technology in its TCR vaccines in development for treatment of multiple sclerosis (MS) and rheumatoid arthritis. XOMA is entitled to royalties on future sales of these products. In December 1997, Connetics successfully completed a Phase I/II study of their MS TCR vaccine. In 1996, XOMA also received a $3.0 million payment for an exclusive license to Genentech, including a sublicense to IDEC Pharmaceuticals Corporation ("IDEC"), to intellectual property covering the use of chimeric IgG1 antibodies specific to the CD20 antigen on the surface of human B-cells. XOMA was entitled to royalties on the sale of products employing the anti-CD20 technology that are sold in the United States and in other countries where XOMA held relevant patents. In December 1997, XOMA assigned these anti-CD20 antibody patents and royalty rights to Pharmaceutical Partners, LLC for $17.0 million. XOMA has granted licenses to a number of biotechnology and pharmaceutical companies for use of patented and proprietary technologies relating to a bacterial expression system used to manufacture recombinant pharmaceutical products. Licensees include: Affymax Research Institute, Cantab Pharmaceuticals Research Ltd, Eli Lilly and Company, Enzon, Inc., the Hoechst Group, ICOS Corporation, Invitrogen Corporation, Pasteur Merieux Serums & Vaccins, and The Pharmacia & Upjohn Group. Genimune(TM) is XOMA's humanized immunofusion product that targets T lymphocytes (white blood cells that attack foreign cells) in autoimmune disease therapy. For several years, the Company developed and evaluated several proprietary variants of genetically-engineered proteins and targeted immunofusions ("TIF"). In mid-1993 the Company selected a lead immunofusion compound designated Genimune(TM). In December 1993, XOMA entered into cross-license agreements with Research Development Foundation concerning recombinant DNA-derived gelonin ("r-gelonin"), a plant-derived cytotoxic enzyme used as a TIF component. In the fourth quarter of 1994, XOMA terminated further internal development of Genimune(TM) and is attempting to outlicense the product, but no assurance can be given that it will successfully do so. Thaumatin, a flavor-enhancing protein developed by XOMA, was classified as generally recognized as safe ("GRAS") by the Flavor and Extract Manufacturer's Association ("FEMA"). GRAS designation permits the use of this ingredient as a flavor enhancer in food without additional regulatory approval. Thaumatin is the first flavoring ingredient produced through biotechnology to be granted GRAS status. The Company is seeking to outlicense this technology, but no assurance can be given that it will successfully do so. Manufacturing XOMA is currently producing its Neuprex(TM) and hu1124 products for clinical trial and other testing needs at its Berkeley manufacturing facility, pursuant to a drug manufacturing license obtained from the State of California. The Company's manufacturing capability is based on recombinant DNA technology, with production of therapeutic proteins from either mammalian or microbial cells. XOMA has fermentation capacity for up to 5500 liters with associated isolation and purification systems in place. The Company does its own formulation for final sterile filling and finishing and has the capacity to do its own small-scale filling. Development and Marketing Arrangements The Company has developed a strategy of entering into arrangements with established pharmaceutical company partners in order to facilitate and finance the development and marketing of its products. Assuming timely regulatory approval, which cannot be assured, the successful commercialization of XOMA's products will be dependent to a large extent upon the marketing capabilities of any pharmaceutical partners. 5 Neuprex(TM) The Company is seeking one or more strategic alliances with respect to its Neuprex(TM) product. Discussions have taken place with several entities regarding such a product alliance. The Company cannot predict whether or when any such alliance(s) will be consummated. hu1124 (antiCD11a) In April 1996, XOMA and Genentech entered into an agreement whereby XOMA agreed to co-develop Genentech's humanized monoclonal antibody product, originally called anti-CD11a. Under the terms of the agreement Genentech purchased 1.5 million shares of XOMA common stock at $5.90/share and is funding development through Phase II by making a series of convertible subordinated loans. XOMA is manufacturing the product, now called hu1124, for clinical trial use and managing clinical trials through Phase II. In April and December 1996 respectively, Genentech loaned $5.0 million and $8.5 million to fund 1996 and 1997 development costs. In December 1997, Genentech loaned an additional $10.0 million to fund 1998 development costs. E5(R) Monoclonal Antibody Product In 1987, XOMA and Pfizer entered into agreements relating to a potentially wide range of monoclonal antibody-based products for the treatment of gram-negative sepsis. Pfizer paid XOMA an initial license fee and made payments based on development progress. In June 1997, the Company announced that Pfizer had decided to end its development and marketing agreements with XOMA. See "Regulatory Process". Other From time to time, the Company reviews development opportunities with other biotechnology companies with a view toward providing process scale-up, regulatory and/or clinical services to them. Competition The biotechnology and pharmaceutical industries are subject to continuous and substantial technological change. Competition in the areas of recombinant DNA-based and monoclonal antibody-based technologies is intense and expected to increase as established biotechnology firms and large chemical and pharmaceutical companies advance in the field. A number of these large pharmaceutical and chemical companies have enhanced their capabilities by entering into arrangements with or acquiring biotechnology companies or entering into business combinations with other large pharmaceutical companies. Many of these companies have significantly greater financial resources, larger research and development and marketing staffs and larger production facilities than those of XOMA. Moreover, certain of these companies have extensive experience in undertaking preclinical testing and human clinical trials. These factors may enable other companies to develop products and processes competitive with or superior to those of the Company. In addition, a significant amount of research in biotechnology is being carried out in universities and other non-profit research organizations. These entities are becoming increasingly interested in the commercial value of their work and may become more aggressive in seeking patent protection and licensing arrangements. There can be no assurance that developments by others will not render the Company's products or technologies obsolete or uncompetitive. The Company is aware of an agreement between Genentech and Incyte Pharmaceuticals, Inc. ("Incyte") pursuant to which Incyte claims to hold worldwide rights to all Incyte and Genentech technology related to BPI. In addition, it is possible that another company may be developing one or more products based on BPI, and there can be no assurance that such product(s) will not prove to be more effective than or receive regulatory approval prior to Neuprex(TM). 6 Regulatory Process XOMA's products are subject to comprehensive preclinical and clinical testing requirements and to approval processes by FDA and similar authorities in other countries. The Company's products are primarily regulated on a product-by-product basis under the U.S. Food, Drug and Cosmetic Act and Section 351(a) of the Public Health Service Act. Most of the Company's human therapeutic products are or will be classified as biologic products and would be subject to regulation by CBER. Approval of a biologic for commercialization requires licensure of the product and the manufacturing facilities. The FDA regulatory process is carried out in several phases. Prior to beginning clinical testing of a proposed new biologic product, an IND is filed with FDA. This document contains scientific information on the proposed product, including results of testing of the product in animal and in vitro or laboratory models. Also included is information on manufacture of the product and studies on toxicity in animals, and a clinical protocol outlining the initial investigation in humans. The initial stage of clinical testing, Phase I, ordinarily encompasses safety, pharmacokinetics and pharmacodynamic evaluations. Phase II testing encompasses investigation in specific disease states designed to provide preliminary efficacy data and additional information on safety. Phase III studies are designed to further establish clinical safety and efficacy and to provide information allowing proper labeling of the product following approval. Phase III studies are most commonly multicenter, randomized, placebo-controlled trials in which rigorous statistical methodology is applied to clinical results. Other designs may also be appropriate in specific circumstances. Following completion of clinical trials, a BLA (Biologics License Application) is submitted to FDA to request marketing approval. Internal FDA committees are formed which evaluate the application, including scientific background information, animal and in vitro or laboratory efficacy studies, toxicology, manufacturing facility and clinical data. During the review process, a dialogue between FDA and the applicant is established in which FDA questions are raised and additional information is submitted. During the final stages of the approval process, FDA generally requests presentation of clinical or other data before an FDA advisory committee. Also, during the later stages of review, FDA conducts an inspection of the manufacturing facility to establish that the product is made in conformity with good manufacturing practice. If all outstanding issues are satisfactorily resolved and labeling established, FDA issues a license for the product and for the manufacturing facility, thereby authorizing commercial distribution. In December 1992, the Company filed an IND with FDA to begin Phase I human testing of its Neuprex(TM) product and, in March 1993, began the testing. Eighteen randomized, double-blind, placebo-controlled Phase I studies have been completed and three Phase II efficacy studies were initiated in 1995. Two other Phase II studies were initiated in 1996 and 1997. In August 1996, the FDA granted XOMA a Subpart E designation for the Neuprex(TM) product for severe pediatric meningococcemia. Subpart E designation is intended to expedite the development, evaluation and marketing of new therapies for life-threatening and debilitating illnesses. In October 1996, XOMA started a Phase III pivotal clinical trial to test the drug for this indication in multiple medical centers in the United States and Canada. In January 1997, the trial was expanded to include sites in the United Kingdom. See "Product Areas - Neuprex(TM)". In November 1997, XOMA initiated a randomized, placebo-controlled, double-blind Phase III pivotal trial to test Neuprex(TM) in patients suffering severe hemorrhage caused by traumatic injury and a Phase I study in CF patients who suffer recurring bacterial lung infections (exacerbations). See "Product Areas - Neuprex(TM)". 7 Other potential XOMA products will require significant additional development, including extensive clinical testing. There can be no assurance that any of the products under development by the Company will be developed successfully, obtain the requisite regulatory approval or be successfully manufactured or marketed. XOMA's product for the treatment of gram-negative sepsis, E5(R), was a murine monoclonal antibody that binds and assists the body to clear bacterial endotoxins. XOMA completed two double-blind, placebo-controlled, Phase III studies of E5(R) involving nearly 1300 patients. In March 1989, XOMA filed a Product License Application ("PLA") for FDA licensure of E5(R). In June 1992, FDA informed XOMA that E5(R) was not approvable without further clinical testing. In June 1993, a third Phase III clinical trial began with narrower entry criteria than previous trials. In April 1997, XOMA and Pfizer decided to discontinue this trial. In June 1997, the Company announced that Pfizer had decided to end its marketing arrangement for E5(R). FDA has substantial discretion in the product approval process and it is not possible to predict at what point, or whether, FDA will be satisfied with the Company's submissions or whether FDA will raise questions which may delay or preclude product approval. As additional clinical data are accumulated, they will be submitted to FDA and may have a material impact on the FDA product approval process. Given that regulatory review is an interactive and continuous process, the Company has adopted a policy of limiting announcements and comments upon the specific details of the ongoing regulatory review of its products, subject to its obligations under the securities laws, until definitive action is taken. Patents and Trade Secrets As a result of its ongoing activities, the Company holds and is in the process of applying for a number of patents in the United States and abroad to protect its products and important processes. The Company also has obtained or has the right to obtain exclusive licenses to certain patents and applications filed by others. However, the patent position of biotechnology companies generally is highly uncertain and no consistent policy regarding the breadth of allowed claims has emerged from the actions of the Patent Office with respect to biotechnology patents. Accordingly, no assurance can be given that the Company's patents will afford protection against competitors with similar technologies, or that others will not obtain patents claiming aspects similar to those covered by the Company's patent applications. During the period from September 1994 to December 1997, the U.S. Patent and Trademark Office (the "Patent Office") issued twenty-one patents to the Company related to its BPI-based products. These BPI-related patents include four directed to novel compounds and compositions, one directed to manufacturing methods, two directed to improved formulations and methods, three directed to BPI and LBP assays and eleven directed to therapeutic uses of BPI protein products, including uses of BPI in conjunction with antibiotics for the treatment of gram-negative and gram-positive bacterial infections. U.S. Patent No. 5,420,019 issued to the Company relates to novel recombinant amino terminal fragments and fragment analogs of BPI and methods for their recombinant production. The Company believes that this patent will provide comprehensive protection for the manufacture, use and sale of its BPI-derived Neuprex(TM) and I-PREX(TM) products in the U.S. The Company has received nine additional Notices of Allowance from the Patent Office and has more than twenty patent applications pending worldwide related to its BPI-based products. In addition to the thirty BPI-related U.S. patents and Notices of Allowance issued to the Company, the Company is the exclusive licensee of BPI-related patents and applications owned by NYU. These include four issued U.S. patents and one additional U.S. Notice of Allowance, directed to novel BPI-related protein and DNA compositions, as well as their production and uses. U.S. Patent No. 5,198,541 issued to NYU relates to the recombinant production of BPI. The Company believes that this patent has substantial value because it covers certain production methodologies that allow production of commercial-scale quantities of BPI for human use. In addition, the European Patent Office granted to NYU, EP 375724, with claims to N-terminal BPI fragments and their use, alone or in conjunction with antibiotics, for the treatment of conditions associated with bacterial infections. 8 Between 1992 and 1996, the Patent Office issued six patents related to BPI to Incyte. Four of these patents originate from one initially-filed application and are directed to endotoxin-associated uses of BPI, one patent is directed to BPI/lipid carrier compositions and one patent relates to uses of BPI with polymannuronic acid. Based on the opinion of its U.S. patent counsel, Marshall, O'Toole, Gerstein, Murray & Borun, the Company believes that it does not infringe any valid claims of any of the Incyte patents. The Company is aware that the European Patent Office granted to Cornell and Rockefeller Universities EP 272489 related to certain neutrophil-derived antimicrobial proteins and the Company believes that Incyte may control this patent. The Company is aware of an agreement between Genentech and Incyte pursuant to which Incyte claims to hold worldwide rights to all Incyte and Genentech technology related to BPI. During the period from July 1991 to December 1997, the Patent Office issued seven patents and one Notice of Allowance to the Company related to its bacterial expression technology, including claims to novel promoter sequences, secretion signal sequences, compositions and methods for expression and secretion of recombinant proteins from bacteria, including immunoglobulin gene products. U.S. Patent No. 5,028,530 issued to the Company is directed to expression vehicles containing an AraB promoter, host cells and processes for regulated expression of recombinant proteins. U.S. Patent No. 5,576,195 is related to DNA encoding a pectate lyase signal sequence, recombinant vectors, host cells and methods for production and externalization of recombinant proteins. U.S. Patent Nos. 5,595,898, 5,698,435 and 5,618,920 address secretable immunoglobulin chains, DNA encoding the chains and methods for their recombinant production. U.S. Patent Nos. 5,693,493 and 5,698,417 relate to methods for recombinant production/secretion of functional immunoglobulin fragments. Numerous foreign patents have been granted which, along with additional pending foreign patent applications, correspond to the patents issued and allowed in the U.S. If certain patents issued to others are upheld or if certain patent applications filed by others issue and are upheld, the Company may require certain licenses from others in order to develop and commercialize certain potential products incorporating the Company's technology. There can be no assurance that such licenses, if required, will be available on acceptable terms. Research and License Agreements XOMA has contracted with a number of academic and institutional collaborators to conduct certain research and development. Under these agreements the Company generally funds either the research and development or evaluation of products, technologies or both, will own or obtain an exclusive license to products or technologies developed, and will pay royalties on sales of products covered by the license. The rates and durations of such royalty payments vary by product and institution, and range generally for periods from five years to indefinite duration. Aggregate expenses of the Company under all of its research agreements totaled $0.2 million, $0.3 million and $0.4 million in 1997, 1996 and 1995, respectively. The Company has entered into certain license agreements with respect to the following products: Bactericidal/Permeability Increasing Protein (BPI) In August 1990, XOMA entered into a research collaboration and license agreement with NYU whereby XOMA obtained an exclusive license to patent rights for DNA materials and genetic engineering methods for the production of BPI and fragments thereof. BPI is part of the body's natural defenses against gram-negative bacteria and XOMA is exploring the use of its Neuprex(TM) and I-PREX(TM) products, based on BPI, for various indications. XOMA has obtained an exclusive, worldwide license for the development, manufacture, sale and use of BPI products for all therapeutic and diagnostic uses, and it has paid a license fee and will make milestone payments and pay royalties to NYU on the sale of such products. The license becomes fully-paid upon the later of the expiration of the relevant patents or fifteen years after the first commercial sale, subject to NYU's right to terminate for certain events of default. 9 Recombinant Technology XOMA has obtained licenses under certain Stanford University and University of California patents relating to certain basic processes of recombinant DNA technology. The Stanford agreement provides that the Company will pay an annual fee and both agreements provide for royalties on sales of products should processes used in making those product(s) come under the licensed patents. E5(R) Monoclonal Antibody Product In conjunction with the decision to discontinue the Phase III E5(R) clinical trial and the termination of Pfizer's marketing agreement with XOMA, the Company's license agreement with the Regents of the University of California has been terminated. Employees As of December 31, 1997 XOMA employed 160 full-time employees at its Berkeley and Santa Monica, California facilities. The Company's employees are engaged in clinical, manufacturing, quality assurance and control, research and product development activities, and in executive, finance and administrative positions. The Company considers its employee relations to be excellent. The Company was incorporated in Delaware in 1981. The principal executive offices of XOMA are located at 2910 Seventh Street, Berkeley, California 94710 (telephone 510-644-1170). Item 2. Properties XOMA's principal product development and manufacturing facilities are located in Berkeley, California. The Company leases 83,000 square feet of space in Berkeley including approximately 35,000 square feet of research and development laboratories, 32,000 square feet of production and production support facilities and 16,000 square feet of office space. An additional 3,000 square feet of office space has been subleased to a third party. Separately, a 16,500 square foot production facility in Berkeley is owned by XOMA. XOMA also maintains offices, laboratories and a manufacturing facility occupying approximately 15,000 square feet in leased space in Santa Monica, California. An additional 6,000 square foot leased facility for scale-up of the Neuprex(TM) product was completed in May 1993. The Company also owns an approximately 6,750 square foot parking lot in Santa Monica. Item 3. Legal Proceedings In the securities class action lawsuit Warshaw, et al. v. XOMA Corporation, et al., the defendants and plaintiffs reached an agreement on March 14, 1997 to settle all claims for $3.75 million in cash and $2.25 million in XOMA common stock. By order entered September 8, 1997, the United States District Court for the Northern District of California approved the settlement. All of the cash portion of the settlement has been paid by insurance into a settlement fund administered by an escrow agent. The claims administration process was deemed complete as of December 16, 1997, and on January 7, 1998, XOMA directed its stock transfer agent to issue and distribute to authorized claimants 344,168 shares of XOMA common stock in accordance with the terms of the court-approved settlement agreement.

(4) Includes cash, cash equivalents, short-term investments, and interest receivable. 13 Excludes current portion.

In 1995, includes $6.5 million aggregate principal amount of convertible debentures due 1998. As of December 31, 1996 all of the convertible debentures had been converted into 2,054,224 shares of Common Stock. Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations Overview XOMA is a biopharmaceutical company developing products to treat infections, infectious complications of traumatic injury and surgery, and immunologic and inflammatory disorders. The Company's primary focus is on products derived from BPI. The first BPI-derived product, Neuprex(TM) is in Phase III pivotal trials in two indications, and earlier stage clinical trials in additional indications. Other BPI-derived products in preclinical testing include I-PREX(TM) a topical ophthalmic product, and Mycoprex(TM), a peptide product targeting systemic fungal infections. XOMA is also developing the hu1124 humanized monoclonal antibody product under a collaboration agreement with Genentech. The product is in Phase II clinical testing for psoriasis. Other indications are under review. Genentech is providing funding for development and clinical trials through a series of long-term convertible loans. The Company incurred a net loss in each of the past three years and is expected to continue to operate at a loss until regulatory approval and commencement of commercial sales of its products. The timing of product approvals is uncertain, and there can be no assurance that approvals will be granted or that revenues from product sales will be sufficient to attain profitability. Revenues Total revenues were $18.4 million in 1997, compared with $3.6 million in 1996 and $1.2 million in 1995. Revenues for 1997 consisted of $17.0 million from the assignment of anti-CD20 antibody patents and royalty rights to Pharmaceutical Partners, LLC and $1.4 million for various licensing transactions. Revenues for 1996 included $3.0 million for licensing of intellectual property related to anti-CD20 antibodies to Genentech, and for 1995 included $0.8 million in partial consideration for the sale of the Company's T cell receptor technology. Costs and Expenses In 1997, research and development expenses increased by $3.5 million, (13%) versus 1996, following a $4.3 million (19%) increase from 1995 to 1996. These increases reflect higher spending on clinical trials and preparing for regulatory applications and inspections for Neuprex(TM) and the initiation of development work and clinical trials for hu1124. The Company anticipates research and development expenditures to continue at similar or higher levels throughout 1998. General and administrative expenses increased by $0.2 million (4%) from 1996 to 1997, following an increase of $0.1 million (1%) from 1995 to 1996. Annual investment income has essentially remained unchanged through the period 1995 - 1997, as improved average cash balances each successive year have been offset by lower prevailing interest rates. Other expense in 1997 included interest on the convertible notes due to Genentech in 2005, which accrues interest at six-months LIBOR plus 1%. Interest expense in 1996 included interest on the Genentech note and also on the Company's 4% Convertible Subordinated Debentures. 14 Other Income (Expense)in 1996 included a provision of $2.5 million for legal fees and settlement costs reflecting an agreement reached with plaintiff's attorney in a class action law suit. An offsetting gain of $0.3 million was realized in 1997 reflecting an adjustment to the value of the settlement. Other Income in 1995 included a one-time gain of $1.9 million related to a modification of the funding arrangement with Pfizer for the E5(R) clinical trial and a write-down of property and equipment. Due to the termination of E5(R) development, the contingent $22.4 million liability to Pfizer has been eliminated. Liquidity and Capital Resources Cash, cash equivalents and short-term investments increased by $8.2 million to $55.1 million at December 31, 1997. Financing activities of $21.7 million included a $10.0 million advance from Genentech under a long-term credit arrangement to fund 1998 development costs of hu1124, and $12.1 million net proceeds from a private placement partially offset by principal payments under capital lease obligations. The Company's cash, cash equivalents and short-term investments are expected to continue to decrease while the Company pursues FDA licensure, except to the extent the Company is able to secure additional funding. Net cash used in operating activities was $12.0 million in 1997, compared with $22.4 million in 1996 and $24.7 million in 1995. The improvement in operating cash flows in 1997 and 1996 is due primarily to cash from licensing transactions, which there can be no assurance will continue. Capital expenditures for 1997, 1996 and 1995 were $1.5 million, $1.1 million and $0.4 million, respectively. A second 2750-liter fermentor train was added to XOMA's Berkeley facility in 1997 to provide additional capacity for Neuprex(TM) and hu1124. The Company intends to continue to fund capital spending from internal cash resources supplemented by capital financing where appropriate and available. The Company's cash position and resulting investment income are sufficient to finance the Company's currently anticipated needs for operating expenses, working capital, equipment and current research projects, for in excess of one year. The Company continues to evaluate strategic alliances, potential partnerships and financing arrangements which would further strengthen its competitive position and provide additional funding. The Company cannot predict whether or when any such alliance(s), partnership(s) or financing(s) will be consummated or whether additional funding will be available when required. Although operations are influenced by general economic conditions, the Company does not believe that inflation had a material impact on financial results for the periods presented. The Company believes that it is not dependent on materials or other resources that would be significantly impacted by inflation or changing economic conditions in the foreseeable future. The Company is currently reviewing its computer systems in order to evaluate necessary modifications for the year 2000. The Company does not currently anticipate that it will incur material expenditures to complete any such modifications. The Company can provide no assurance that there will be no year 2000 impact through third parties, such as suppliers of raw materials for manufacturing and clinical research organizations.

Report of Independent Public Accountants Balance Sheets Statements of Operations Statements of Stockholders' Equity Statements of Cash Flows Notes to Financial Statements Item 9. Change in Accountants On March 19, 1998, the Company appointed Ernst & Young, LLP ("Ernst & Young") to serve as the Company's independent accountants for 1998, the ratification of which appointment will be submitted to the stockholders at the Company's 1998 annual meeting. From fiscal 1983 through fiscal 1997, Arthur Andersen, LLP ("Arthur Andersen") acted as the Company's independent accountants. Arthur Andersen was dismissed on March 19, 1998. The decision to change accountants was approved by the audit committee of the Board of Directors. The reports of Arthur Andersen on the financial statements of the Company for the two most recent fiscal years did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. During the Company's two most recent fiscal years and all subsequent interim periods preceding such dismissal, there were no disagreements with Arthur Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Arthur Andersen, would have caused it to make a reference to the subject matter of disagreements in connection with its reports; nor has Arthur Andersen ever presented a written report, or otherwise communicated in writing to the Company or Board of Directors or the audit committee thereof the existence of any "disagreement" or "reportable event" within the meaning of Item 304 of Regulation S-K. The Company has authorized Arthur Andersen to respond fully to the inquiries of Ernst & Young. The letter from Arthur Andersen addressed to the Securities and Exchange Commission (the "SEC"), as required by Item 304 (a) (3) of Regulation S-K, will be filed as an exhibit to this Annual Report on Form 10-K by amendment. 16 PART III Item 10.

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of XOMA Corporation as of December 31, 1997 and 1996, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 1997 in conformity with generally accepted accounting principles.

The accompanying notes are an integral part of these financial statements. 25 XOMA CORPORATION NOTES TO FINANCIAL STATEMENTS 1. OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Business XOMA Corporation ("XOMA" or the "Company") is a biopharmaceutical company developing products to treat infections, infectious complications of traumatic injury and surgery, and immunologic and inflammatory disorders. The Company's products are presently in various stages of development and all are subject to regulatory approval before the Company can commercially introduce any products. There can be no assurance that any of the products under development by the Company will be developed successfully, obtain the requisite regulatory approval or be successfully manufactured or marketed. The Company's cash position and resulting investment income are sufficient to finance the Company's currently anticipated needs for operating expenses, working capital, equipment and current research projects for in excess of one year. The Company continues to evaluate strategic alliances, potential partnerships, and financing arrangements which would further strengthen its competitive position and provide additional funding. The Company cannot predict whether or when any such alliance(s), partnership(s) or financing(s) will be consummated or whether additional funding will be available when required. Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. Net Loss Per Common Share Net loss per common share is based on the weighted average number of common shares outstanding in accordance with Financial Accounting Standard No. 128. 26 Reconciliation of the numerator and the denominator of basic and diluted net loss per share was derived as follows (in thousands, except per share amounts):

Subsequent to December 31, 1997 the Company issued 344,168 shares of common stock in settlement of a securities class action lawsuit(see Note 6). Cash and Cash Equivalents For the purpose of the statements of cash flows, the Company considers all highly liquid debt instruments with maturities of three months or less at the time the Company acquires them to be cash equivalents, except when such debt instruments are part of a portfolio of investments managed by an independent, outside investment manager, in which case these instruments are classified as short-term investments. 27 Supplemental Cash Flow Information Cash paid for interest was $0.1 million, $0.2 million, and $0.1 million during the years ended December 31, 1997, 1996, and 1995, respectively.

Property and Equipment Property and equipment, including equipment under capital leases, are stated at cost. Equipment depreciation is calculated using the straight-line method over the estimated useful lives of the assets (five to seven years). Leasehold improvements, buildings, and building improvements are amortized and depreciated using the straight-line method over the shorter of the lease terms or the useful lives (one to seven years). Property and equipment consist of the following (in thousands): December 31 1997 1996 ---- ---- Equipment $15,545 $14,500 Leasehold and building improvements 14,836 14,483 Construction-in-progress 97 208 ------- ------- 30,478 29,191 Less accumulated depreciation and amortization 25,914 24,093 ------- ------- Property and equipment, net $ 4,564 $ 5,098 ======= ======= Assets held for sale $ 4,442 $ 4,442 ======= ======= The Company owns a facility originally intended for the production of CD5 Plus(TM) intermediates, which was re-classified as an asset held for sale in 1995 and written down to an estimated realizable value of $4.4 million resulting in a charge to Other income and expense of $2.4 million. The amount the Company will ultimately realize could differ materially from the amount assumed in arriving at the realizable value. 28 Accrued Liabilities Accrued liabilities consist of the following (in thousands): December 31 1997 1996 ---- ---- Accrued legal costs $ 198 $ 661 Accrued dividends 810 586 Accrued payroll costs 1,986 1,573 Provision for litigation settlement 2,028 2,500 Clinical trial costs 1,203 521 Other 187 303 ------ ------ $6,412 $6,144 ====== ====== Activities through December 31, 1997 affecting the provision for litigation settlement established in 1996 are as follows (in millions): Original amount $2.5 Charges against the accrual 0.2 Adjustment to the accrual 0.3 In December 1997, the Company elected to settle the claim through the issuance of 344,168 shares of common stock which resulted in a $0.3 million reduction in the accrual. The liability was eliminated in January 1998 upon issuance of the shares. Research and Development Fees Research and development fees are recognized as revenues as research activities are performed or as development milestones are completed under the terms of research and development agreements. The excess of total research and development expense over revenues recognized under collaborative agreements amounted to $29.9 million, $26.4 million, and $22.1 million for the years 1997, 1996, and 1995, respectively. Reclassifications Certain reclassifications have been made to conform the prior years to the 1997 presentation. New Accounting Standards In June 1997, the Financial Accounting Standards Board issued a final statement on reporting comprehensive income. The adoption of the standard as required on January 1, 1998 will not have a material impact on the Company's financial statements. 2. CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS On December 31, 1997 and 1996, cash and cash equivalents consisted mostly of money market mutual funds. The Company follows a policy of investing only in marketable debt securities and holding them to maturity; however, since the Company has from time to time sold certain securities to meet cash requirements or improve investment diversification, the Company's short-term investments have been categorized as available-for-sale. 29 The aggregate fair values, amortized cost, gross unrealized holding gain, and gross unrealized holding loss of the major types of debt securities at December 31, 1997 were as follows (in millions):
Gross Unrealized Holding Fair Amortized Value Cost Gain Loss U.S. Treasury Securities $9.5 $9.5 $ -- $ -- Corporate Bonds and Other 8.4 8.4 -- --
The contractual maturities of the Company's debt securities as of December 31, 1997 were as follows (in millions): Less than 1 year $11.4 From 1 to 2 years 4.0 More than 2 years 2.5 During the year ended December 31, 1997, gross realized losses on available-for-sale securities were negligible and the net change in the unrealized gain or loss was negligible. Gross realized gains were negligible. Gains and losses are determined on a specific identification basis. As of December 31, 1997, short-term investments included $0.1 million in certificates of deposit which guaranteed a standby letter of credit. 3. RESEARCH AND DEVELOPMENT AGREEMENTS In April 1996, the Company entered into a collaborative agreement with Genentech, Inc. ("Genentech") to jointly develop hull24 (anti-CD11a), for treatment of psoriasis and for organ transplant rejection. In connection therewith, Genentech purchased 1.5 million shares of common stock for approximately $9 million and has agreed to fund the Company's development costs for hull24 until the completion of Phase II clinical trials through a series of convertible subordinated notes. During 1996, Genentech made loans totaling $13.5 million ($5.0 and $8.5 million, respectively, for funding 1996 and 1997 clinical trials and development costs) to XOMA under this arrangement. An additional loan of $10.0 million was made in December 1997 to fund 1998 costs. Under the terms of the agreement, the Company will scale up and develop hull24 and bring it through Phase II clinical trials. After completion of Phase II trials, Genentech will determine the product's future development strategy. In May 1996, the Company announced the granting of an exclusive license to Genentech, including a sublicense to IDEC Pharmaceuticals Corporation, to intellectual property covering the therapeutic use of chimeric IgG1 antibodies specific to the CD20 antigen on the surface of human B-cells. The Company received an initial cash payment of $3.0 million and the right to receive royalties on the sale of products employing the anti-CD20 technology that are sold in the United States and in other countries where the Company held relevant patents. In December 1997, the Company assigned the related patents and royalty rights to Pharmaceutical Partners, LLC for $17.0 million and recognized this amount as license fee revenue. In June 1994, the Company assigned its exclusive worldwide rights in T cell receptor ("TCR") peptide technology to Connetics. The Company received a promissory note in the amount of $1.4 million and warrants to purchase 450,000 shares of Connetics. stock, and will receive milestone payments and royalties on product sales. In 1995, the Company received an additional note in the amount of $0.8 million pursuant to the terms of the original assignment. The notes were paid in full in February 1996 and the warrants cancelled. In 1995, XOMA and Pfizer modified the funding arrangement of the then current E5(R) clinical trial and of certain patent litigation costs. As a result, the Company recorded a $4.3 million gain in Other income. 30 In June 1997, the Company announced that Pfizer had ended its agreements with the Company relating to monoclonal antibody-based products for the treatment of gram-negative sepsis, which resulted in the elimination of the contingent $22.4 million liability to Pfizer. XOMA has granted licenses to a number of biotechnology and pharmaceutical companies for use of patented and proprietary technologies relating to a bacterial expression system used to manufacture recombinant pharmaceutical products. Licensees include: Affymax Research Institute, Cantab Pharmaceuticals Research Ltd, Eli Lilly and Company, Enzon, Inc., the Hoechst Group, ICOS Corporation, Pasteur Merieux Serums & Vaccins, and The Pharmacia & Upjohn Group. 4. CAPITAL STOCK Common Stock In April 1996, Genentech purchased 1.5 million shares of common stock for approximately $5.90 per share in connection with the collaborative agreement to develop jointly Genentech's anti-CD11a monoclonal antibody product, hull24. In March 1996, the Company completed a private placement exempt from registration under the Securities Act of 1933 in reliance on Regulation D thereunder, issuing 606,061 shares of Common Stock for net proceeds of $1.9 million. In June and July 1995, the Company issued 470,859 shares of Common Stock in reliance on Regulation S for net proceeds of $0.7 million. Preferred Stock In August 1997, the Company completed a private placement exempt from registration under the Securities Act of 1933 in reliance on Section 4(2) thereof, issuing 1,250 shares in the form of 5% Convertible Preferred Stock, Series G ("Series G Preferred") for proceeds of approximately $12.1 million net of cash issuance costs. The same investors have also committed to provide additional financing of up to $12.5 million at XOMA's option, subject to certain conditions. Conversions of Series G Preferred will be based on the price of Common Stock at the time of conversion. There is no initial discount on the conversion price, but a discount of 2% will be added for each month the Series G Preferred is held, up to a maximum discount of 14%, for which an additional $1.3 million has been added to dividends and charged to Paid-in capital as of December 31, 1997. No conversions were permitted below a price of $7.80 for the first 60 days. The maximum conversion price for the first six months was $9.10. There are certain restrictions on the volume of sales of underlying Common Stock by the investors. The investors also received three-year warrants to purchase up to a total of 432,000 common shares at a price of $10.00 per share. The additional funding commitment also provides for limits on conversion price and trading, and additional warrants, all based on the market price of Common Stock at the time such funding is provided. Additional warrants to purchase 54,000 common shares at the $10.00 price were issued to the placement agents. In September 1996, the Company completed a private placement exempt from registration under the Securities Act of 1933 in reliance on Regulation D thereunder, issuing 1,600 shares of its Convertible Preferred Stock, Series F ("Series F Preferred") for proceeds of approximately $15.0 million net of issuance costs. As of December 31, 1996, all of the Series F Preferred, plus accrued dividends, had been converted into 5,269,870 shares of Common Stock. 31 In March 1996, the Company completed a private placement exempt from registration under the Securities Act of 1933 in reliance on Regulation D thereunder, issuing 5,000 shares of its Convertible Preferred Stock, Series D ("Series D Preferred") for proceeds of $4.8 million net of issuance costs.

In August 1995, the Company issued 4,799 shares of its Convertible Preferred Stock, Series C ("Series C Preferred") to foreign investors in an offering exempt from registration under the Securities Act of 1933 in reliance on Regulation S thereunder. The offering yielded proceeds to the Company of $4.1 million net of issuance costs. As of December 31, 1995, all of the Series C Preferred, plus accrued dividends, had been converted into 2,728,190 shares of Common Stock. In December 1993, the Company issued 18,775 shares of Senior Convertible Preferred Stock, Series B ("Series B Preferred") to two investors for proceeds of $17.7 million net of issuance costs. Costs of the issue were approximately $1.1 million. An additional 250 shares of Series B Preferred were issued to the placement agent as part of the fee for investment banking services. In May 1994, the placement agent converted all 250 of its shares of preferred stock into 47,595 shares of Common Stock. The amounts payable as dividends at December 31, 1994 were paid with 252,745 shares of common stock in January of 1995. During 1995, 7,808 shares of the Series B Preferred had been converted into 1,501,731 shares of Common Stock. The remaining 7,807 shares were converted into 1,648,115 shares of Common Stock in 1996 prior to the June 1996 dividend date. The Company has authorized 650,000 shares of Series A Cumulative Preferred Stock of which none were outstanding at December 31, 1997, 1996 and 1995. (See "Stockholder Rights Plan", below.) Convertible Notes and Debentures Under the arrangement with Genentech (see Note 3) the Company receives funding for development of hull24 in the form of convertible subordinated notes due 2005 at interest rates of LIBOR plus 1% compounded and reset at the end of June and December each year. Interest is payable at maturity. The Company has received $5.0 million and $8.5 million of these loans, respectively, in April and December of 1996, and a further $10.0 million in December 1997. The notes are convertible into one share of Series E Preferred Stock (7,500 shares are so designated) for each $10,000 in notes. The Series E Preferred Stock is convertible into common stock. The cumulative amount of interest accrued was $1.2 million and $0.3 million as of December 31, 1997 and 1996, respectively. In November 1995, the Company issued $6.5 million aggregate principal amount of 4% Convertible Subordinated Debentures due in 1998 to foreign investors in an offering exempt from registration under the Securities Act of 1933 in reliance on Regulation S thereunder. The offering yielded net proceeds to the Company of $5.9 million net of issuance costs. During the first quarter of 1996 all of the Debentures, plus accrued interest, were converted into 2,054,224 shares of Common Stock. Unamortized issuance costs of $0.6 million were charged to Paid-in capital in connection with the conversions of the Debentures. Management Incentive Compensation Plan The Board of Directors of the Company established a Management Incentive Compensation Plan effective July 1, 1993 (as amended, the "Incentive Plan"), in which management employees (other than the Chief Executive Officer), as well as certain additional discretionary participants chosen by the Chief Executive Officer, are eligible to participate. 32 Awards under the Incentive Plan vest over a three-year period with 50% of each award payable on a date to be determined, expected to be in the first quarter of the following fiscal year, and 25% payable on each of the next two annual distribution dates, so long as the participant continues to participate in the Incentive Plan. The amounts charged to expense under the Incentive Plan were $0.8 million, $0.7 million and $0.6 million for the plan years 1997, 1996 and 1995 respectively. Stockholder Rights Plan In October 1993, the Company's Board of Directors unanimously adopted a Stockholder Rights Plan (the "Rights Plan"). Under the Rights Plan, Preferred Stock Purchase Rights ("Rights") were distributed as a dividend at the rate of one Right for each share of the Company's Common Stock held of record as of the close of business on November 12, 1993. Each Right entitles the registered holder of Common Stock to buy a fraction of a share of the new series of Preferred Stock (the "Series A Preferred Stock") at an exercise price of $30.00, subject to adjustment. The Rights will be exercisable, and will detach from the Common Stock, only if a person or group acquires 20 percent or more of the Common Stock, announces a tender or exchange offer that if consummated will result in a person or group beneficially owning 20 percent or more of the Common Stock, or if the Board of Directors declares a person or group owning 10 percent or more of the outstanding shares of Common Stock to be an Adverse Person (as defined in the Rights Plan). Once exercisable, each Right will entitle the holder (other than the acquiring person) to purchase units of Series A Preferred Stock (or, in certain circumstances, common stock of the acquiring person) with a value of twice the Rights exercise price. The Company will generally be entitled to redeem the Rights at $.001 per Right at any time until the close of business on the tenth day after the Rights become exercisable. The Rights will expire at the close of business on December 31, 2002. 5. STOCK OPTIONS AND WARRANTS At December 31, 1997, the Company had three stock-based compensation plans, which are described below. The aggregate number of shares of Common Stock that may be issued under these plans is 5,300,000 shares. Stock Option Plan Under the Company's amended 1981 Stock Option Plan (the "Option Plan"), qualified and non-qualified options of the Company's Common Stock may be granted to certain employees and other individuals as determined by the Board of Directors at not less than the fair market value of the stock at the date of grant. Options granted under the Option Plan may be exercised when vested and expire five years and two months to ten years from the date of grant or three months from the date of termination of employment. Options granted generally vest over five years. The Option Plan will terminate on November 15, 2001. As of December 31, 1997, options covering 3,132,386 shares of Common Stock were outstanding under the Option Plan. Restricted Stock Plan The Company also has a Restricted Stock Plan (the "Restricted Plan") which provides for the issuance of options or the direct sale of Common Stock to certain employees and other individuals as determined by the Board of Directors at not less than 85% of fair market value of the Common Stock on the grant date. Each option issued under the Restricted Plan will be a non-statutory option under the federal tax laws and will have a term not in excess of ten years from the grant date. Options granted generally vest over five years. The Restricted Plan will terminate on December 15, 2003. 33 The Company has granted options with exercise prices at 85% of fair market value on the date of grant. Up to 1,200,000 shares are authorized for issuance under the Restricted Plan. As of December 31, 1997, options covering 537,479 shares of Common Stock were outstanding under the Restricted Plan. The Company amortizes deferred compensation, which is the difference between the issuance price or exercise price and the fair market value of the shares as determined by the Board of Directors at the date of sale or grant over the period benefited. Directors Stock Option Plan In 1992, the stockholders approved a Directors Stock Option Plan (the "Directors Plan") which provides for the issuance of options to purchase shares of Common Stock to non-employee directors of the Company at 100% of the fair market value of the stock on the date of the grant. Up to 150,000 shares are authorized for issuance during the term of the Directors Plan. Options vest on the date of grant and have a term of up to ten years. As of December 31, 1997, options for 50,000 shares of Common Stock were outstanding under the Directors Plan. The Company applies APB Opinion 25 and related interpretations in accounting for its plans. Accordingly, the financial statements reflect amortization of compensation resulting from options granted at exercise prices which were below market price at the grant date. Had compensation cost for the Company's stock-based compensation plans been based on the fair value at the grant dates for awards under these plans consistent with the provisions of FASB Statement 123, the Company's net loss and loss per share would have been increased to the pro forma amounts indicated below for the years ended December 31 (in thousands except per share amounts):
1997 1996 1995 ---- ---- ---- Net loss As reported $(15,765) $(29,110) $(22,472) Pro forma $(17,639) $(30,213) $(23,953) Net loss per share As reported $ (0.44) $ (0.90) $ (0.97) Pro forma $ (0.48) $ (0.94) $ (1.04)
The fair value of each option grant under these plans is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions used for grants during the years indicated below: 1997 1996 1995 ---- ---- ---- Dividend yield 0% 0% 0% Expected volatility 71% 73% 73% Risk-free interest rate 6.3% 5.2% 7.6% Expected life 7 years 7 years 6 years 34 A summary of the status of the Company's stock option plans as of December 31, 1997, 1996, and 1995, and changes during years ending on those dates is presented below:

COMMITMENTS AND CONTINGENCIES Clinical Trial Due to the termination of E5(R) development in mid-1997, the contingent $22.4 million in future reduced royalties from Pfizer has been eliminated. Collaborative Agreements and Royalties As of December 31, 1997, the Company has commitments under research agreements with universities and other research institutions that require the Company to fund research in the amount of $0.1 million through August 1998. Research and development expenses include research agreement expenses of approximately $0.2 million, $0.3 million, and $0.4 million for the years ended December 31, 1997, 1996 and 1995, respectively. The Company is also obligated to pay royalties, ranging generally from 1.5% to 5% of the selling price of the licensed component and up to 25% of sublicense fee income, to various universities and other research institutions based on future sales or licensing of products that incorporate certain products and technologies developed by those institutions. Leases As of December 31, 1997, the Company leased administrative, research facilities, certain laboratory and office equipment under operating and capital leases expiring on various dates through 2008. 36 Future minimum lease commitments are as follows (in thousands): Capital Leases Operating Leases 1998 $ 753 $ 2,427 1999 -- 2,413 2000 -- 2,439 2001 -- 2,239 2002 -- 2,239 Thereafter -- 12,378 ----- ------- Net minimum lease payments 753 $24,135 ======= Less--Amount representing interest expense 46 ----- Present value of net minimum lease payments 707 Less--Current maturities 707 ----- Long-term capital lease obligations $ -- ===== Total rental expense was approximately $2.0 million, $2.0 million, and $2.3 million for the years ended December 31, 1997, 1996, and 1995, respectively. Legal Proceedings In the securities class action lawsuit Warshaw, et al. v. XOMA Corporation, et al., the defendants and plaintiffs reached an agreement on March 14, 1997 to settle all claims for $3.75 million in cash and $2.25 million in Common Stock. By order entered September 8, 1997, the United States District Court for the Northern District of California approved the settlement. All of the cash portion of the settlement has been paid by insurance into a settlement fund administered by an escrow agent. The claims administration process was deemed complete as of December 16, 1997, and on January 7, 1998, XOMA directed its stock transfer agent to issue and distribute to authorized claimants 344,168 shares of Common Stock in accordance with the terms of the court-approved settlement agreement. Liability Insurance The testing and marketing of medical and food additive products entails an inherent risk of allegations of product liability. XOMA believes that its product liability insurance levels are adequate for its clinical trial activity. XOMA will seek to obtain additional insurance, if needed, if and when the Company's products are commercialized; however, there can be no assurance that adequate insurance coverage will be available or be available at acceptable costs or that a product liability claim would not materially adversely affect the business or financial condition of the Company. The Company insures and indemnifies its directors and officers against actions brought against them as a result of their management of the Company's operations. There can be no assurance that adequate directors and officers insurance coverage will be available or be available at acceptable costs or that a claim against the directors and officers would not materially adversely affect the business or financial condition of the Company. 37 7.

Certain future changes in the ownership of significant shareholders could limit utilization of the Company's tax NOLs and credits. 8.
