DOCUMENTS INCORPORATED BY REFERENCE ----------------------------------- Portions of the Company's Proxy Statement for the Company's 1996 Annual Meeting of Stockholders are incorporated by reference into Part III of this Report. PART I ITEM 1. BUSINESS GENERAL XOMA Corporation ("XOMA" or the "Company") is a biopharmaceutical company developing products for the treatment of infectious diseases and major complications due to infections, traumatic injury and surgery. The Company's current product development programs include: o Neuprex(TM), a recombinantly-derived fragment of human bactericidal/permeability-increasing protein ("BPI") and XOMA's lead BPI product, which is currently in efficacy clinical trials for four different indications. o I-PREX(TM), a proprietary topical formulation of BPI for the treatment of ophthalmic disorders, which is undergoing preclinical testing as a treatment for corneal ulcerations and transplants. o Mycoprex(TM), a potent fungicidal peptide compound derived from BPI that is currently in preclinical product development. o E5(R), XOMA's monoclonal antibody product, which is in a Phase III trial in the United States as a treatment for gram-negative sepsis and has been submitted for approval in Japan as a treatment for endotoxemia. PRODUCT AREAS The following describes XOMA's significant therapeutic product development and clinical activities: The BPI Product Platform The Company's current programs are primarily focused on the development of therapeutic products derived from BPI. BPI is a naturally-occurring human host- defense protein found in white blood cells (neutrophils). BPI kills bacteria, apparently by permeating bacterial cell walls. It also neutralizes poisonous endotoxins produced on the surface of gram-negative bacteria, which can trigger severe complications in infected patients. Furthermore, BPI inhibits angiogenesis (growth of new blood vessels) by binding to heparin, a natural protein involved in blood vessel formation. XOMA scientists developed a modified recombinant fragment of the BPI molecule, called rBPI21, which is potent and stable and can be manufactured in commercially viable quantities. This fragment is the basis for the Company's Neuprex(TM) product. 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 initiated human safety and pharmocokinetic testing under the IND. In mid-1995, the Company initiated three clinical efficacy trials testing the Neuprex(TM) product as a treatment for bacterial endotoxin-related conditions. A fourth trial started in the first quarter of 1996. XOMA has an agreement with New York University ("NYU") relating to its rBPI products. See "Research and License Agreements." In March 1993, the U.S. Patent and Trademark Office ("Patent Office") issued a patent related to BPI to NYU, and the Company is the exclusive licensee of this patent. The Company is aware of an agreement between Genentech Inc. ("Genentech") and Incyte Pharmaceuticals Inc. ("Incyte") pursuant to which Incyte claims to hold worldwide rights to all Incyte and Genentech technology related to BPI and through which Genentech will receive a royalty on Incyte's BPI product sales. Between 1992 and 1994, the Patent -2- Office issued five patents related to BPI to Incyte. Based on the opinion of its 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. See "Patents and Trade Secrets." Neuprex(TM) In the second quarter of 1995, XOMA started three clinical trials evaluating Neuprex(TM) as a treatment for bacterial endotoxin-related conditions. The indications are: o Meningococcemia: a potentially deadly bacterial infection that usually afflicts children, characterized by extremely high endotoxin levels. o Hemorrhagic trauma: accidents or injuries that cause acute blood loss may trigger serious complications, possibly from translocation of endotoxin or endotoxin-carrying bacteria from the gastrointestinal tract into the bloodstream. o Partial hepatectomy: surgical removal of part of the liver, usually to remove an isolated tumor. Since the liver clears endotoxin, the resulting temporarily impaired liver function can lead to endotoxin- related complications. In the first quarter of 1996, the Company started a fourth clinical trial for Neuprex(TM) to be used with conventional antibiotics in the treatment of severe intra-abdominal infections, including those caused by antibiotic-resistant organisms. 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 associated with eye infections. This neovascularization can lead to scarring and permanently impaired vision. In preclinical testing, the I-PREX(TM) product has shown anti-infective 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 ulcers and other corneal diseases could eliminate the need for therapies, such as those with corticosteroids, which have undesirable side effects. Mycoprex(TM) XOMA scientists discovered that certain peptide sequences derived from BPI displayed potent fungicidal activity. Further research demonstrated that many of these compounds not only killed strains of Candida, the most common fungi to cause systemic illness, but also showed activity against other strains of fungi including fungi resistant to the currently available drugs. Based on these findings, the Company has initiated a program to screen for compounds with a broad spectrum of potent fungicidal activity and a better safety profile than currently-available fungicidals. The Company has selected a lead antifungal compound and several alternates and has moved them from the research phase into product development. E5(R) Monoclonal Antibody Product The term sepsis is commonly used to describe a severe systemic inflammatory response by the body's immune system to invasion by bacteria. Sepsis can be a complication of many different underlying causes, including infections, cancer, trauma, massive blood loss and surgery. Gram-negative sepsis refers to sepsis caused by infection by gram-negative bacteria. Gram-negative bacteria are distinctive because their cell walls contain endotoxin (lipopolysaccharide or LPS), a chemical that can trigger the -3- inflammatory cascade that leads to sepsis. Thus, sepsis could be thought of as late-stage endotoxin poisoning. XOMA's product for the treatment of gram-negative sepsis, E5(R), is a murine monoclonal antibody that neutralizes the effects of endotoxin. XOMA has completed several clinical trials of E5(R), including two randomized, double-blind, placebo-controlled, multi-center Phase III studies involving nearly 1300 patients. In March 1989, XOMA filed a Product License Application ("PLA") for FDA licensure of E5(R). In September 1991, an FDA advisory committee heard E5(R) data presentations but made no recommendations regarding the safety or efficacy of the product. 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 of the E5(R) product began with narrower entry criteria than the previous trials. The trial is being managed and co-funded by Pfizer Inc. ("Pfizer"). In December 1995, an independent Data Safety Monitoring Board ("DSMB") completed the first of two planned interim analyses for this trial. The data were not disclosed to XOMA or to Pfizer. The DSMB found no evidence suggesting safety concerns and concluded that the results met predetermined criteria for continuing the trial. There can be no assurance that the continuing trial will yield data that will result in licensure of E5(R) in the U.S. See "Development and Marketing Arrangements." In October 1993, Pfizer submitted an application for approval to market E5(R) for endotoxin reduction to regulatory authorities in Japan. There can be no assurance that such application will be approved. See "Development and Marketing Arrangements". Genimune(TM) XOMA believes there is potential for the use of a T lymphocyte-targeted product 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 and named it 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 enzyme that is a component of the Company's TIF program. In the fourth quarter of 1994, XOMA terminated further internal development of Genimune(TM) and is attempting to outlicense the product. See "Research and License Agreements." Additional Product Areas XOMA continues to review alternatives to realize value from products and technologies outside the scope of its core research efforts, including immunoconjugates, immunofusions, bacterial and mammalian expression technology, osteoinductive proteins for bone repair, and non-cariogenic proteins for low- calorie flavor enhancement. Several licenses and sublicenses have been entered into in these areas, and discussions are ongoing with various 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. MANUFACTURING XOMA is currently producing its Neuprex(TM) product for clinical and toxicological testing needs at its Berkeley and Santa Monica facilities, pursuant to a drug manufacturing license obtained from the State of California. The Company's E5(R) manufacturing facilities are located in Berkeley, California. The Company's manufacturing capabilities include: recombinant technology- based production; the purification of monoclonal antibodies; the isolation and purification of cytotoxic enzymes and their fragments; the conjugation of monoclonal antibodies to such enzymes and/or fragments to form immunoconjugates; the formulation of pharmaceutical products for final sterile filling and finishing; and the capacity to do small-scale filling. FDA licensure of XOMA's -4- manufacturing facilities will be required prior to any commercial use or sale of Neuprex(TM), E5(R) or any other product. XOMA obtains the unpurified ascites containing the monoclonal antibodies used in its E5(R) product from a single supplier, Charles River Laboratories ("CRL"), which has multiple manufacturing sites. XOMA and CRL entered into a supply agreement in February 1989 and renewed the agreement in October 1991, committing CRL to supply and the Company to purchase its anticipated ascites needs for five years after FDA licensure of E5(R). Among the requirements for FDA licensure of E5(R) is that the CRL manufacturing facilities be licensed by FDA. If the Company must obtain ascites from other sources, including its own facilities or a different facility of the same supplier, regulatory licensure of such other sources will be required. Although XOMA believes that it currently has sufficient quantities of ascites for product launch and the first few years of sales, any significant future interruption in supply could materially and adversely affect the Company's business relating to E5(R). Pfizer currently sterile-fills, packages and distributes E5(R) at a manufacturing plant in Brooklyn, New York. FDA licensure of this facility and the related process also is required. In the future, Pfizer may carry out some or all of the manufacturing processes for the production of the purified bulk E5(R) intermediate product, supplementing XOMA's current manufacturing capacity. If so, additional FDA licensure would be required. During December 1991 and January 1992 XOMA, CRL and Pfizer facilities were inspected for licensure by the FDA with respect to E5(R) and XOMA believes that there are no major manufacturing issues outstanding. Such licenses are currently pending and will not be finalized unless and until E5(R) has been approved for sale. The Company has accumulated inventories of raw material and intermediates for E5(R). Because the achievement, timing and terms of regulatory licensures and subsequent sales of pharmaceutical products are uncertain, there can be no assurance that the inventories of raw materials and intermediates will be usable. In connection with its October 1992 restructuring, the Company established a $6.0 million reserve for a portion of its E5(R) inventory and recorded a $2.5 million charge to earnings for future idle manufacturing capacity. The Company increased the reserve to $6.9 million in 1993 and to $11.1 million in 1995 to cover the entire value of the inventory. DEVELOPMENT AND MARKETING ARRANGEMENTS The Company has developed a strategy of entering into arrangements with established pharmaceutical company partners in order to facilitate and help fund 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 its pharmaceutical partners. Neuprex(TM) The Company has engaged an investment banking firm to assist it in completing one or more strategic alliances with respect to its Neuprex(TM) product. The Company cannot predict whether or when any such alliance(s) will be consummated. E5(R) Monoclonal Antibody Product In June 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. XOMA believes that Pfizer's marketing force and experience in the development and marketing of anti-infective products, which are expected to be used in conjunction with E5(R), make Pfizer a strong partner and will contribute to the effective marketing of E5(R). The agreements provide Pfizer -5- with exclusive rights to E5(R) in exchange for funding of certain clinical and development activities. In January 1994, the territory covered by the agreements was redefined to include only the countries of Japan and the United States. Pfizer paid XOMA an initial license fee and has made payments based on development progress. XOMA is reimbursed for manufacturing costs and will receive a portion of the gross profits obtained from any sales on a formula basis. Pfizer also has a limited first right to negotiate for future XOMA products, other than BPI-derived products, if they will be used for the treatment, cure or prevention of gram-negative sepsis. The agreements can be canceled with appropriate notice upon reimbursement by Pfizer of certain of XOMA's research and development expenses. XOMA has granted a security interest to Pfizer in assets related to its E5(R) program to secure performance of XOMA's obligations under the agreements under certain conditions, including bankruptcy. In the third quarter of 1995, XOMA and Pfizer agreed to modify the funding arrangement of the current E5(R) clinical trial and the payment terms relating to certain patent litigation costs (see Notes 1 and 6 to the Financial Statements). The Company believes that termination of its relationship with Pfizer could have a material adverse effect on its future revenues and prospects. 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 in the future as a number of established biotechnology firms and large chemical and pharmaceutical companies diversify into the field. A number of these large pharmaceutical and chemical companies have enhanced their capabilities by entering into arrangements with or acquiring biotechnology companies. Substantially all of these companies have significantly greater financial resources, larger research and development and marketing staffs and larger production facilities than those of the Company. Moreover, certain of these companies have extensive experience in undertaking preclinical testing and human clinical trials. These factors may enable such 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 aware of 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. Earlier in the 1990's, a number of corporations including Centocor, Inc., Synergen, Inc. and Chiron, Inc. discontinued development of products (like E5(R)) designed to treat gram negative sepsis. These actions may have a material adverse effect on the regulatory review of E5(R), and there can be no assurance that E5(R) will receive regulatory approval or that Pfizer will be able to market E5(R) effectively. The Company believes that research and human testing is being conducted with other products, some of which are designed to treat a broader population of sepsis patients, including patients with gram-positive as well as gram-negative sepsis. E5(R) is intended to treat only patients with severe gram- negative sepsis. There is no assurance, however, that products currently unknown to the Company will not prove to be more effective than or receive regulatory approval prior to E5(R). In addition, it is possible that Incyte or some other company is 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 Neuprex(TM). -6- REGULATORY PROCESS XOMA's products are subject to rigorous 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 the FDA Center for Biologics Evaluation and Research. 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 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 definitively to document clinical safety and efficacy and to provide information allowing proper labelling 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 are also appropriate in specific circumstances. Following completion of clinical trials, a PLA is submitted to FDA to request marketing approval. For biologic products, an internal FDA committee is formed which evaluates the application, including scientific background information, animal and in vitro efficacy studies, toxicology, manufacturing and control and clinical data. Concurrently with the filing of the PLA, an establishment license application is filed which describes in detail the manufacturing facility, personnel, procedures and equipment used in the manufacture of the product. During the review process, a dialogue between FDA and the applicant is established during which FDA questions on both applications 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 labelling established, FDA issues licenses for the product and for the manufacturing facility, thereby authorizing commercial distribution. In March 1989, XOMA filed a PLA for approval of E5(R), a monoclonal antibody product, for the treatment of gram-negative sepsis. FDA responded to the PLA with a request for additional information, including clinical data. XOMA made a further submission and met and corresponded with the FDA on relevant matters. In September 1991, an FDA advisory committee heard E5(R) data presentations but made no recommendations regarding the safety or efficacy of the product. 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 of the E5(R) product began with narrower entry criteria than the previous trials. The trial is being managed and co-funded by Pfizer Inc. There can be no assurance that the continuing trial will yield data that will result in licensure of E5(R) in the U.S. See "Product Areas--E5(R) Monoclonal Antibody Product" and Note 1 to the Financial Statements. In December 1991 and January 1992 the manufacturing facility for E5(R) was inspected for licensure by FDA. XOMA believes there are no major manufacturing issues outstanding. The license is currently pending but will not be finalized unless and until the relevant product has been approved for sale. -7- 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. Three randomized, double-blind, placebo-controlled Phase I studies have been completed and three Phase II efficacy studies were initiated in 1995. See "Product Areas--Neuprex(TM)". 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. 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 February 1996, the Patent Office issued nine patents to the Company related to its BPI-based products, including novel compositions, their manufacture, formulation, assay and use. The Patent Office issued to the Company U.S. Patent No. 5,420,019 in May 1995 which is directed 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. In September 1995, the Patent Office issued U.S. Patent No. 5,447,913 which addresses novel pharmaceutical compositions of dimeric BPI protein products, including rBPI42, with enhanced biological activities. In addition to such composition patents, U.S. Patent No. 5,439,807 issued to the Company in August 1995 addresses improved manufacturing methods for the Company's BPI-related products and U.S. Patent No. 5,488,034 issued to the Company in January 1996 describes novel pharmaceutical formulations of BPI-based protein products, including the Company's Neuprex(TM) product formulation. The Company's first two diagnostic assay patents, U.S. Patent Nos. 5,466,580 and 5,466,581, were issued in November 1995 and describe methods for quantifying BPI levels in blood as well as screening methods for detecting increased levels of BPI in septic patients. The Company's third diagnostic assay patent, U.S. Patent No. 5,484,705, was issued in January 1996 directed to methods of measuring levels of lipopolysaccharide-binding protein ("LBP") elevated in humans as a specific response to bacterial endotoxin exposure. In addition to such composition, manufacturing, formulation and assay patents, the Company has been issued two patents related to therapeutic uses of BPI-derived proteins. In September 1994, U.S. Patent No. 5,348,942 was issued addressing the use of BPI protein products for neutralizing anti-coagulant effects of heparin. In February 1996, the Patent Office issued U.S. Patent -8- No. 5,494,896 directed to methods of treating burn injuries with BPI protein products. In addition to the nine BPI-related U.S. patents issued to the Company, the Company is the exclusive licensee of three BPI-related patents owned by NYU. In March 1993, the Patent Office issued to NYU U.S. Patent No. 5,198,541 (the "'541 patent") which contains claims covering the recombinant production of BPI. The Company believes the '541 patent has substantial value because it covers certain production methodologies that allow production of commercial-scale quantities of BPI for human use. In February 1996, the Patent Office issued U.S. Patent No. 5,489,676 to NYU, relating to the discovery of novel polypeptides that potentiate BPI's ability to kill gram-negative bacteria. In May 1995, the European Patent Office granted to NYU, EP 375724, with claims to N-terminal BPI fragments and their use, alone or in combination with antibiotics, for the treatment conditions associated with bacterial infections. This patent is the first and only BPI-related patent that has been granted to date in Europe. The Company has also received four more U.S. Notices of Allowance and has more than twenty pending patent applications for its BPI-based products. 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 and through which Genentech will receive a royalty on Incyte's BPI product sales. Between 1992 and 1994, the Patent Office issued five patents related to BPI to Incyte. Based on the opinion of its 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 the exclusive licensee of U.S. Patent No. 4,918,163 (the "`163 Patent"), issued to The Regents of the University of California in April of 1990. The `163 Patent relates to a method of treating gram-negative bacterial infection using certain anti-endotoxin monoclonal antibodies. On the date of issuance, the Company filed suit against Centocor alleging infringement of the `163 Patent. Effective July 28, 1992, the Company, Centocor and all other interested parties resolved all outstanding litigation and disputes worldwide regarding products, patents and patent applications related to anti-endotoxin monoclonal antibodies by consent judgements which held the `163 Patent valid and infringed by Centocor. Centocor has agreed to pay royalties to XOMA for any United States sales of its monoclonal antibody HA-1A, and the companies have agreed to forego all future litigation and administrative proceedings regarding certain of each other's patents and patent applications related to anti-endotoxin monoclonal antibodies. In March, 1993, Centocor announced the cancellation of the Phase III trial of its HA-1A product. 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 totalled $0.4 million, $0.4 million, and $0.8 million in 1995, 1994, and 1993, respectively. The Company has entered into certain license agreements with respect to the following products: -9- Bactericidal/Permeability Increasing Protein 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 defense 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 human 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. E5(R) Monoclonal Antibody Product In September 1986, XOMA obtained from the University of California an exclusive license to several monoclonal antibody cell lines related to virulence factors of gram-negative bacteria. One of these monoclonal antibodies is being used in the Company's E5(R) anti-endotoxin product described herein. The Company has entered into an exclusive, worldwide license agreement for this product which provides for the payment of royalties on sales of products utilizing this antibody. The license becomes fully paid upon the later of the expiration of relevant patents or ten years after the first commercial sale, subject to the University's right to terminate the license for certain events of default. 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. EMPLOYEES As of December 31, 1995 XOMA employed 129 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 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 98,000 square feet of space 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. The Company subleased 14,000 square feet of office space as a result of the restructing. An additional 16,500 square foot production facility was completed and purchased by XOMA during 1992. A decision was made during the third quarter of 1995 to dispose of this facility. 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 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. -10- ITEM 3. LEGAL PROCEEDINGS In June 1992, the Company and one of its officers were named in a securities class action lawsuit entitled Warshaw et al. v. XOMA Corporation, et al. filed in the United States District Court for the Northern District of California. The suit alleges that the Company failed to adequately disclose information related to FDA review of the Company's application for a license to market its E5(R) product for the treatment of gram-negative sepsis. The suit seeks unspecified damages for alleged violations of Section 10(b) of the Securities Exchange Act of 1934. After permitting plaintiffs to amend their complaint three times, the District Court granted defendants' motion to dismiss the third amended complaint with prejudice by Memorandum and Order dated June 23, 1994. Plaintiffs filed appeals with the U.S. Court of Appeals for the Ninth Circuit on July 22 and 26, 1994. On January 25, 1996, the Court of Appeals reversed the District Court and remanded the case to the District Court for further proceedings, finding that the allegations of the plaintiffs' third amended complaint were sufficient to withstand a motion to dismiss. Defendants filed a petition for rehearing and suggestion for rehearing en banc on February 8, 1996. On February 16, 1996, the Court of Appeals requested that plaintiffs file a response to defendants' petition for rehearing, which plaintiffs filed on March 1, 1996. The Court of Appeals has not yet ruled on the petition for rehearing. The Company maintains that all material information related to FDA review of its application to market E5(R) had been publicly disclosed on a timely basis, and that neither the Company nor the officer named engaged in any wrongdoing. The Company believes that the allegations contained in the suit are without merit, and it intends to defend against the suit vigorously. ITEM 4.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OVERVIEW XOMA is a biopharmaceutical company engaged in the development of products for the treatment of infections and complications from traumatic injury and surgery. The Company is developing its Neuprex(TM) product for the treatment of gram-negative infections and bacterial endotoxin-related complications. Other BPI-derived products are in development, such as I-PREX(TM), for treating ophthalmic infections and disorders, and Mycoprex(TM), for treating systemic fungal infections. The Company's monoclonal antibody product, E5(R), is in clinical testing in the United States as a treatment for gram-negative sepsis, and has been submitted for approval in Japan as a treatment for endotoxemia. In December 1994, XOMA restructured its operations to reduce costs and focus on the development of its portfolio of advanced products. Under the restructuring, XOMA's work force was reduced at its facilities in Berkeley and Santa Monica, California. Although the restructuring will preserve the functions essential to the development of Neuprex(TM) and certain other products derived from BPI, several research programs with longer lead times and a need for substantial funding were curtailed or eliminated. The Company incurred a net loss in each of the past three years and is expected to continue to operate at a loss at least until regulatory approval and commencement of commercial sales of its products occurs. However, 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 $1.2 million in 1995, $1.7 million in 1994, and $0.6 million in 1993. Revenues for 1995 and 1994 included $0.8 million and $1.4 million respectively in partial consideration for the sale of the Company's T-cell receptor ("TCR") technology. Since it is not possible to predict when or whether it will receive regulatory approval for its products, the Company has established a reserve of $11.1 million for its entire E5(R) inventory. COSTS AND EXPENSES Due to the regulatory status of the Company's E5(R) product, there has been no significant production of this product, from 1993 through 1995. In 1995, research and development expenses decreased by $5.2 million from 1994 expenses, which were $0.4 million above 1993 expenses. The 1995 decrease was due primarily to the restructuring at the end of 1994. The 1994 increase was due primarily to the cost of BPI toxicology studies, partially offset by lower personnel, supplies and outside research costs. General and administrative expenses decreased by $3.3 million in 1995 primarily due to the effect of the 1994 restructuring. The $0.5 million increase of 1994 over 1993 was principally the result of additional corporate salaries and overhead related to Neuprex(TM) and Genimune(TM) project management. In the fourth quarter of 1994, the Company recorded a $2.5 million charge for the cost of termination benefits related to the restructuring of operations to reduce costs and to accelerate development of Neuprex(TM) and the other products derived from BPI. Investment income decreased by $0.2 million in 1995 compared with 1994 and by $1.4 million in 1994 compared with 1993 due primarily to lower average investment balances partially offset by higher interest rates. -15- During the third quarter of 1995, XOMA reached an agreement with Pfizer to amend the cost sharing arrangement for the current ongoing Phase III clinical trial for the Company's E5(R) product and certain other matters. This amendment gives the Company the option to pay a reduced share of future costs for this trial, in return for reduced future royalty payments by Pfizer on U.S. sales of the product. The Company has also increased its reserves against its E5(R) inventories to provide a 100 percent reserve. Finally, the Company made the decision to attempt to sell its facility which was to be used for the production of its CD5 Plus(TM) product and has re-classified it for financial reporting purposes as an asset held for sale. The net result of these actions was a one-time gain recorded in Other Income/(Expense) of $1.9 million ($0.08 per share). LIQUIDITY AND CAPITAL RESOURCES Cash, cash equivalents, and short-term investments decreased by $13.2 million during 1995 primarily as a result of operating cash requirements of $24.6 million, and capital expenditures and lease payments of $0.8 million, offset by $1.8 million from a sale and leaseback transaction, $5.9 million from debt incurrence, and $4.5 million from the issuance of equity. Cash used in operating activities was $24.6 million in 1995. This was primarily due to the net loss of $22.5 million plus a $3.9 million reduction in accrued liabilities and an $8.5 million reduction in non-current liabilities, partially offset by a $4.2 million increase to inventory reserves, $2.9 million in charges for depreciation and amortization and a $2.4 million valuation reduction in certain fixed assets which have been re-classified as property held for sale. The $3.9 million reduction in accrued liabilities included $2.3 million in payments for re-structuring costs recorded in 1994, and a $2.0 million payment to Pfizer for previously recorded clinical trial costs. The reduction in non-current liabilities related to the elimination of an $8.5 million litigation liability to Pfizer (see Notes 1 and 6 to the Financial Statements). Capital expenditures totalled $0.3 million in 1995, $1.3 million in 1994 and $1.8 million in 1993. Included in 1994 and 1993 were purchases of research and manufacturing equipment and capital costs associated with the expansion of the Neuprex(TM) product manufacturing facilities in Santa Monica and Berkeley. In the near term, the Company intends to continue to fund capital expenditures 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 a minimum 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 has engaged an investment banking firm to assist in completing one or more strategic alliances with respect to the Neuprex(TM) product. The Company cannot predict whether or when any such alliance(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 revenues or expenses for the periods presented. The Company believes it is not dependent on materials or other resources which would be significantly impacted by inflation or changing economic conditions in the foreseeable future. -16- ITEM 8.

OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Business XOMA Corporation ("XOMA" or the "Company") is a biotechnology and pharmaceutical company engaged in the development of products for the treatment of infectious and immune system diseases and other serious disorders. The Company's products are presently in various stages of development or regulatory review 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 a minimum 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 has engaged an investment banking firm to assist in completing one or more strategic alliances with respect to the Neuprex(TM) product. The Company cannot predict whether or when any such alliance(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 from those estimates. Amendment to Pfizer Agreement In the third quarter of 1995, XOMA and Pfizer Inc. ("Pfizer") agreed to modify the funding arrangement of the current E5(R) clinical trial, so that XOMA may at its option reduce its contributions towards the cost in return for a reduction in future royalties otherwise payable by Pfizer. The agreement also modifies the payment terms relating to the Company's $8.5 million obligation to Pfizer for patent litigation costs. See Note 6, Commitments and Contingencies. The maximum royalty reduction in any one year will be limited to 30% of the royalties otherwise payable on Pfizer's U.S. sales of E5(R), until such time as the amounts owed are fully paid. Pfizer was also paid $2.0 million for previously recorded clinical trial costs. Restructuring Charges In the fourth quarter of 1994, the Company restructured its operations to reduce costs and to accelerate the development of its Neuprex(TM) and other BPI derived products. Other research programs will be curtailed or eliminated. The Company recorded a charge to earnings of $2.5 million, primarily from the cost of termination benefits related to the elimination of 75 positions in research and research support functions. -27- The activities during 1995 affecting the restructuring accrual established in the fourth quarter of 1994 are as follows: In Millions Original amount accrued $2.5 Charges against the accrual 2.3 Adjustments to the accrual -- Net Loss Per Common Share Net loss per common share is based on the weighted average number of common shares outstanding. Shares issuable upon exercise of options and warrants are not considered in the computation of net loss per share because the effect of including such shares in the computation would be antidilutive. Shares of Common Stock issuable upon conversion of Preferred Stock and Convertible Debentures outstanding at December 31, 1995 and 1994 are not considered because the shares of Preferred Stock and Convertible Debentures are not Common Stock equivalents. 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. Supplemental Cash Flow Information Cash paid for interest during the years ended December 31, 1995, 1994, and 1993 was as follows (in thousands): 1995 1994 1993 ---- ---- ---- Interest $105 $119 $206 In addition, during the years ended December 31, 1995, 1994 and 1993, the Company had the following non-cash financing and investing activities (in thousands): 1995 1994 1993 ---- ---- ---- Stock contribution to the 401(k) and management incentive plans (Notes 4 and 9) $ 434 $ 360 $-- Litigation settled with issuance of warrants (Note 5) -- -- 3,000 Stock issuance cost paid with common or preferred stock (Note 4) 8 -- 250 Unrealized loss(gain) on investments 125 128 -- -28- Notes Receivable The $2.2 million in notes receivable from Connective Therapeutics, Inc. was collected in February of 1996. In 1994, the note for $1.4 million was classified as long-term in Deposits and other. Inventories Inventories are stated at the lower of first-in-first-out cost or market value. Inventories consist of the following (in thousands): DECEMBER 31 - - --------------------------- 1995 1994 ---- - - ---- Raw materials $ -- $4,170 Work-in-process -- -- Finished goods -- -- ------ - - ------ $ -- $4,170 ====== ====== The inventories consist primarily of E5(R) raw materials net of a reserve of $11.1 million and $6.9 million in 1995 and 1994, respectively. The $4.2 million increase in the reserves in the third quarter of 1995 was charged to Other income and expense. 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 nine years). Property and equipment consist of the following (in thousands): DECEMBER 31 - - --------------------------- 1995 1994 ---- - - ---- Land $ -- $ 459 Buildings -- 1,714 Equipment 13,916 15,557 Leasehold and building improvements 14,483 20,342 Construction-in-progress 19 117 -------- - - ------ 28,418 38,189 Less accumulated depreciation and amortization 22,237 22,741 ------- - - ------ Property and equipment, net $ 6,181 $15,448 ======= ======= Assets held for sale $ 4,442 $ - - -- ======= ===== In 1994, land, buildings, equipment and building improvements included approximately $7.2 million related to the net book value of a facility originally intended for the production of CD5 Plus(TM) intermediates, which was classified as assets held for sale in 1995. The facility was written down to estimated realizable value of $4.4 million which resulted in a charge to other income and expense of $2.4 million in the third quarter of 1995. The amounts the Company will ultimately realize could differ materially from the amounts assumed in arriving at the realizable value. -29- Deposits and other Deposits and other included $1.4 million in 1994 for a note receivable from Connective Therapeutics, Inc. and was reclassified to notes receivable in 1995. Accrued Liabilities Accrued liabilities consist of the following (in thousands): DECEMBER 31 - - --------------------------- 1995 1994 ---- - - ---- Accrued legal costs $ 500 $ 1,098 Accrued dividends 586 781 Accrued payroll costs 1,492 1,134 Restructuring costs 172 2,500 Clinical trial costs 593 2,611 Other 341 538 ------- - - ------- $ 3,684 $ 8,662 ======= ======= Other Non-current Liabilities Liabilities or loss accruals are classified as non-current if their expected payment dates or amortization periods (if non-cash) occur more than one year from the balance sheet date. Other non-current liabilities in 1994 consisted of $8.5 million of patent litigation costs. 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 $22.1 million, $27.0 million, and $26.6 million for the years 1995, 1994, and 1993, respectively. Reclassifications Certain reclassifications have been made to conform the prior years to the 1995 presentation. 2. CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS On December 31, 1995 and 1994, cash and cash equivalents consisted mostly of money market mutual funds. Effective January 1, 1994, the Company implemented the provisions of Statement of Financial Accounting Standards ("SFAS") 115, "Accounting for Certain Investment in Debt and Equity Securities". Adoption of SFAS 115, a change in accounting principle, had no material cumulative effect on retained earnings as of that date. 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 as required by SFAS 115. -30- 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, 1995 were as follows (in millions): Gross Unrealized Holding - - ----------------- Fair Amortized Value Cost Gain Loss ----- --------- ---- ---- U.S. Treasury Securities $1.7 $1.7 $ -- $ -- U.S Government Agency Issues 3.0 3.0 -- -- Corporate Bonds and Other 1.3 1.3 -- -- The contractual maturities of the Company's debt securities as of December 31, 1995 were as follows (in millions): Less than 1 year $5.4 From 1 to 2 years 0.6 More than 2 years -- During the year ended December 31, 1995, gross realized losses on available-for-sale securities were negligible and the net change in the unrealized gain or loss was a $0.1 million gain. Gross realized gains were negligible. Gains and losses are determined on a specific identification basis. As of December 31, 1995, term investments includes $0.6 million in certificates of deposit which guarantees a standby letter of credit in favor of the Lessor of the $1.8 million sale and lease back of certain equipment in July of 1995. 3. RESEARCH AND DEVELOPMENT AGREEMENTS In June 1994, the Company assigned its exclusive worldwide rights in T-cell receptor ("TCR") peptide technology to Connective Therapeutics, Inc. The Company received a promissory note in the amount of $1.4 million and warrants to purchase 450,000 shares of Connective Therapeutics, Inc. 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. In June 1987, the Company and Pfizer entered into agreements relating to monoclonal antibody-based products for the treatment of gram-negative sepsis. The agreements provide Pfizer with exclusive rights to E5(R) in exchange for the funding of certain clinical and development activities. In January 1994, the territory covered by the agreements was redefined to include only the countries of Japan and the United States. Research and development fees earned under the agreements were negligible over the last three years. The Company is reimbursed for manufacturing costs and will receive a portion of the gross margins obtained from any sales on a formula basis. Pfizer also has a limited first right to negotiate for future XOMA products (other than BPI-derived products) if they will be used for the treatment, cure or prevention of gram-negative sepsis. The agreements can be canceled with appropriate notice upon reimbursement by Pfizer of certain of XOMA's research and development expenses. XOMA has granted a security interest to Pfizer in assets related to its E5(R) program to secure performance of XOMA's obligations under the agreements under certain conditions, including bankruptcy. In the third quarter of 1995, XOMA and Pfizer agreed to modify the funding -31- arrangement of the current E5(R) clinical trial and the payment terms relating to certain patent litigation costs (see Note 1, Operations and Summary of Significant Accounting Policies, Amendment to Pfizer Agreement, and Note 6, Commitments and Contingencies). 4. CAPITAL STOCK Common Stock In June and July 1995, the Company issued 470,859 shares of common stock in reliance on Regulations S for net proceeds of $0.7 million. Preferred Stock The Company has authorized 650,000 shares of Series A Cumulative Preferred Stock of which none were outstanding at December 31, 1995 and 1994. (See Stockholder Rights Plan, below.) In December 1993, the Company issued 18,775 shares of Senior Convertible Preferred Stock, Series B ("Series B Preferred Stock"), $.05 par value, to two investors for proceeds of $18.8 million. In addition, warrants to purchase 1,787,210 shares of Common Stock were issued to the two investors (see Note 5, Stock Options and Warrants). Costs of the issue were approximately $1.1 million. Of the net proceeds, $3.0 million have been allocated to the warrants. An additional 250 shares of Series B Preferred Stock and 23,770 warrants were issued to the placement agent as part of the fee for investment banking services. A total of 30,000 shares of Series B Preferred Stock was authorized for this transaction. Each share of Series B Preferred Stock has a liquidation preference of $1,000 per share and a cumulative annual dividend of $50 per share payable semiannually in cash or Common Stock at the Company's discretion, and is convertible into 206.2442 shares of Common Stock (subject to certain anti-dilution adjustments). In May of 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 Stock had been converted into 1,501,731 shares of Common Stock and the warrants to purchase 1,787,210 shares of Common Stock had expired unexercised. In August 1995, the Company issued 4,799 shares of its Convertible Preferred Stock, Series C 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 after expenses of $4.1 million. As of December 31, 1995, all of the Series C Preferred Stock had been converted into 2,728,190 shares of Common Stock. Debentures 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 after expenses of $5.9 million. Beginning 45 days after issuance, 50% of the principal amount of the Debentures, and beginning 75 days thereafter, all of the outstanding principal amount thereof, will be convertible by the holder into Common Stock of the Company at a conversion price equal to 80% of the then current market price of the Common Stock. -32- After two years the Debentures may be converted by the Company at the same conversion price. The Company will not be required to issue more than approximately 4.9 million shares of Common Stock upon conversion 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. Under the Incentive Plan, at the beginning of each fiscal year, the Board of Directors (with advice from the Compensation Committee) establishes a target incentive compensation pool, which is adjusted at year-end to reflect the Company's performance in achieving its corporate objectives. After each fiscal year, the Board of Directors and the Compensation Committee make a determination as to the performance of the Company and Incentive Plan participants in meeting corporate objectives and individual objectives, which are determined from time to time by the Board of Directors in its sole discretion. Awards to Incentive Plan participants will vary depending upon the achievement of corporate objectives, the size of the incentive compensation pool, the Incentive Plan participants' base salaries and the Incentive Plan participants' performance during the fiscal year and expected ongoing contribution to the Company. The Company must meet a minimum percentage of its corporate objectives (currently 70%) before any awards will be made under the Incentive Plan. 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 Incentive Plan participant continues to participate in the Incentive Plan. The portion payable on the first distribution date is payable 50% in cash and 50% in Common Stock (based on a 10-day average market price). Incentive Plan participants must choose prior to the end of the first year of the three-year period whether the balance is to be paid in cash or Common Stock. If, within a year after a "change in control" (as defined) of the Company, an Incentive Plan participant's employment is involuntarily terminated other than for cause or an Incentive Plan participant voluntarily terminates his or her employment because his or her duties or compensation are no longer substantially equivalent to what they were at the time of the "change in control," then all awards authorized but not yet distributed to the Incentive Plan participant will be distributed. The amounts accrued under the Incentive Plan were $0.6 million and $0.3 million for the plan years 1995 and 1993 respectively. There was no accrual for 1994. 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 -33- 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 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, 1995, options covering 2,392,401 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. Individuals eligible to receive option grants or stock issuances under the Restricted Plan will be limited to those employees (including officers and directors) who have contributed to the management, growth or financial success of the Company. During 1992 the number of shares of Common Stock authorized for issuance over the term of the Restricted Plan was increased to 1,000,000, subject to the aggregate limitation discussed below. 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. The Company has granted options with exercise prices at 85% of fair market value on the date of grant. As of December 31, 1995, options covering 412,720 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 benefitted. -34- 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, 1995, options for 33,000 shares of Common Stock were outstanding under the Directors Plan. Ingene Plan In connection with the merger with International Genetic Engineering, Inc. ("Ingene"), the Company assumed the rights and obligations of Ingene under then outstanding options to purchase shares of Ingene Common Stock. After the merger, the outstanding Ingene options became options to purchase 134,800 shares of XOMA Corporation Common Stock. No options can be granted under the Ingene Plan subsequent to the merger. These options expire ten years after the date of original grant by Ingene and become exercisable ratably over periods of up to four years starting from one year after the date of original grant. All options are fully vested at December 31, 1994. As of December 31, 1995, options for 8,896 shares of common stock were outstanding under this plan. The aggregate number of shares of Common Stock that may be issued under the Option Plan, the Restricted Plan, the Directors Plan and the Ingene Plan is 4,300,000 shares. The following table summarizes the activity under the Company's stock option plans: Year ended Year ended Year ended December 31, December 31, December 31, 1995 1994 1993 ------ ------ ----- Exercise Exercise Exercise Options Price Options Price Options Price ------- -------- ------- --------- ------- -------- Outstanding, beginning of period 3,000,692 $2.07-26.50 2,861,854 $4.99-26.50 2,806,700 $7.00-28.00 Granted 2,239,855 $1.70-2.94 517,000 $2.07-4.38 846,300 $4.99-7.50 Exercised (5,315) $1.81-2.56 -- -- -- -- Canceled (2,388,215) $2.38-26.50 (378,162) $3.72-26.50 (791,146) $6.38-28.00 ----------- -------- -------- Outstanding, end of period 2,847,017 $1.70-22.75 3,000,692 $2.07-26.50 2,861,854 $4.99-26.50 ----------- --------- --------- Exercisable, end of period 1,310,938 $1.70-22.75 1,480,886 $2.07-26.50 1,364,943 $4.99-26.50 ========== ========= ========= Warrants Warrants to purchase 1,810,980 shares of Common Stock issued in conjunction with the issuance of the Series B Preferred Stock in December 1993 expired on December 19, 1995. These warrants were valued at $3.0 million and are reflected in Paid-in capital. Warrants with an aggregate value of $3.0 million at the time of issuance were issued during the second quarter of 1993 to conclude the settlement of certain stockholder and derivative litigation brought in 1991. A total of 2,214,633 warrants were issued, and warrants for 2,213,476 shares of Common Stock expired unexercised in June of 1995. -35- 6. COMMITMENTS AND CONTINGENCIES Clinical Trial In the third quarter of 1995, the Company and Pfizer reached an agreement regarding the funding of the current Phase III E5(R) clinical trial and payment terms relating to the $8.5 million of patent litigation costs due to Pfizer. Under this agreement, the Company may, at its option, reduce its minimum funding commitment ($3.6 million at December 31, 1995) for the remainder of the trial in return for a reduction in future royalties otherwise payable to XOMA by Pfizer on Pfizer's U.S. sales of E5(R). The agreement also provides that XOMA will repay the $8.5 million of patent litigation costs by reducing the future royalties otherwise payable to XOMA by Pfizer on Pfizer's U.S. sales of E5(R). As a result, the $8.5 million was credited to Other income and expense in the third quarter of 1995. The maximum royalty reduction in any one year related to these items will be limited to 30% of the royalties otherwise payable on Pfizer's U.S. sales of E5(R), until such time as the amounts owed ($9.9 million at December 31, 1995) are fully paid. Collaborative Agreements and Royalties As of December 31, 1995, the Company has commitments under research agreements with universities and other research institutions that require the Company to fund research in the amount of $0.2 million through December 1996. Research and development expenses include research agreement expenses of approximately $0.4 million, $0.4 million, and $0.8 million for the years ended December 31, 1995, 1994 and 1993, 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, 1995, the Company leased administrative, research facilities, certain laboratory and office equipment under operating and capital leases expiring on various dates through 2003. -36- Future minimum lease commitments are as follows (in thousands): Capital Leases Operating Leases 1996 $ 744 $ 1,824 1997 623 1,761 1998 753 916 1999 -- 571 2000 -- 571 Thereafter -- 1,569 ------- - - -------- Net minimum lease payments 2,120 $ 7,212 ======= Less--Amount representing interest expense 382 Present value of net minimum lease payments 1,738 Less--Current maturities 546 ------- Long-term capital lease obligations $ 1,192 ======= Total rental expense was approximately $2.3 million, $2.3 million, and $2.5 million for the years ended December 31, 1995, 1994, and 1993, respectively. Patents As a result of its ongoing activities, the Company owns and is in the process of applying for a number of patents in the United States and abroad which may 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 February 1996, the U.S. Patent and Trademark Office (the "Patent Office") issued nine patents to the Company related to its BPI-based products, including novel compositions, their manufacture, formulation, assay and use. The Patent Office issued to the Company U.S. Patent No. 5,420,019 in May 1995 which is directed 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. In September 1995, the Patent Office issued U.S. Patent No. 5,447,913 which addresses novel pharmaceutical compositions of dimeric BPI protein products, including rBPI42, with enhanced biological activities. In addition to such composition patents, U.S. Patent No. 5,439,807 issued to the Company in August 1995 addresses improved manufacturing methods for the Company's BPI-related products and U.S. Patent No. 5,488,034 issued to the Company in January 1996 describes novel pharmaceutical formulations of BPI-based protein products, including the Company's Neuprex(TM) product formulation. The Company's first two diagnostic assay patents, U.S. Patent Nos. 5,466,580 and 5,466,581, were issued in November 1995 and describe methods for quantifying BPI levels in blood as well as screening methods for detecting increased levels of BPI in septic patients. The Company's third diagnostic assay patent, U.S. Patent No. 5,484,705, was issued in January 1996 directed to methods of measuring levels of lipopolysaccharide-binding protein -37- ("LBP") elevated in humans as a specific response to bacterial endotoxin exposure. In addition to such composition, manufacturing, formulation and assay patents, the Company has been issued two patents related to therapeutic uses of BPI-derived proteins. In September 1994, U.S. Patent No. 5,348,942 was issued addressing the use of BPI protein products for neutralizing anti- coagulant effects of heparin. In February 1996, the Patent Office issued U.S. Patent No. 5,494,896 directed to methods of treating burn injuries with BPI protein products. In addition to the nine BPI-related U.S. patents issued to the Company, the Company is the exclusive licensee of three BPI-related patents owned by New York University ("NYU"). In March 1993, the Patent Office issued to NYU U.S. Patent No. 5,198,541 (the "`541 patent") which contains claims covering the recombinant production of BPI. The Company believes the '541 patent has substantial value because it covers certain production methodologies that allow production of commercial-scale quantities of BPI for human use. In February 1996, the Patent Office issued U.S. Patent No. 5,489,676 to NYU, relating to the discovery of novel polypeptides that potentiate BPI's ability to kill gram-negative bacteria. In May 1995, the European Patent Office granted to NYU, EP 375724, with claims to N-terminal BPI fragments and their use, alone or in combination with antibiotics, for the treatment conditions associated with bacterial infections. This patent is the first and only BPI-related patent that has been granted to date in Europe. The Company has also received four more U.S. Notices of Allowance and has more than twenty pending patent applications for its BPI-based products. 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 and through which Genentech will receive a royalty on Incyte's BPI product sales. Between 1992 and 1994, the Patent Office issued five patents related to BPI to Incyte. Based on the opinion of its 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 the exclusive licensee of U.S. Patent No. 4,918,163 (the "`163 Patent"), issued to The Regents of the University of California in April 1990. The `163 Patent relates to a method of treating gram-negative bacterial infection using certain anti-endotoxin monoclonal antibodies. On the date of issuance, the Company filed suit against Centocor alleging infringement of the `163 Patent. Effective July 28, 1992, the Company, Centocor and all other interested parties resolved all outstanding litigation and disputes worldwide regarding products, patents and patent applications related to anti-endotoxin monoclonal antibodies by consent judgements which held the `163 Patent valid and infringed by Centocor. Centocor has agreed to pay royalties to XOMA for any United States sales of its monoclonal antibody HA-1A, and the companies have agreed to forego all future litigation and administrative proceedings regarding certain of each other's patents and patent applications related to anti-endotoxin monoclonal antibodies. In March, 1993, Centocor announced the termination of a Phase III trial of its HA-1A product. 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. -38- Legal Proceedings In June 1992, the Company and one of its officers were named in a securities class action lawsuit entitled Warshaw et al. v. XOMA Corporation, et al. filed in the United States District Court for the Northern District of California. The suit alleges that the Company failed to adequately disclose information related to FDA review of the Company's application for a license to market its E5(R) product for the treatment of gram-negative sepsis. The suit seeks unspecified damages for alleged violations of Section 10(b) of the Securities Exchange Act of 1934. After permitting plaintiffs to amend their complaint three times, the District Court granted defendants' motion to dismiss the third amended complaint with prejudice by Memorandum and Order dated June 23, 1994. Plaintiffs filed appeals with the U.S. Court of Appeals for the Ninth Circuit on July 22 and 26, 1994. On January 25, 1996, the Court of Appeals reversed the District Court and remanded the case to the District Court for further proceedings, finding that the allegations of the plaintiffs' third amended complaint were sufficient to withstand a motion to dismiss. Defendants filed a petition for rehearing and suggestion for rehearing en banc on February 8, 1996. On February 16, 1996, the Court of Appeals requested that plaintiffs file a response to defendants' petition for rehearing, which plaintiffs filed on March 1, 1996. The Court of Appeals has not yet ruled on the petition for rehearing. The Company maintains that all material information related to FDA review of its application to market E5(R) had been publicly disclosed on a timely basis, and that neither the Company nor the officer named engaged in any wrongdoing. The Company believes that the allegations contained in the suit are without merit, and it intends to defend against the suit vigorously. 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. -39- 7.

RELATED PARTY TRANSACTIONS Certain directors and stockholders of the Company are or have been principals of investment banking firms which have performed investment banking services for the Company. These firms have received customary discounts, fees, and commissions in connection with these services.

DEFERRED SAVINGS PLAN Under section 401(k) of the Internal Revenue Code of 1986, the Board of Directors adopted, effective June 1, 1987, a tax-qualified deferred compensation plan for employees of the Company.

The Company may, at its sole discretion, make contributions each plan year, in cash or in shares of the Company's Common Stock in amounts which match up to 100% of the salary deferred by the participants.
