See accompanying notes 5 6 PROTEIN DESIGN LABS, INC. NOTES TO UNAUDITED FINANCIAL STATEMENTS JUNE 30, 1996 1. ORGANIZATION AND BUSINESS. Protein Design Labs, Inc. (the "Company") is a biotechnology company incorporated in the State of Delaware on July 24, 1986. The Company is engaged in the research and development of human therapeutic products based on the concept of protein engineering. 2. BASIS OF PRESENTATION AND RESPONSIBILITY FOR INTERIM FINANCIAL STATEMENTS. The balance sheet as of June 30, 1996 and the statements of operations and cash flows for the six month periods ended June 30, 1996 and 1995 are unaudited but include all adjustments (consisting of normal recurring adjustments) which the Company considers necessary for a fair presentation of the financial position at such dates and the operating results and cash flows for those periods. Although the Company believes that the disclosures in these financial statements are adequate to make the information presented not misleading, certain information and footnote information normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. The accompanying financial statements should be read in conjunction with the Company's Annual Report on Form 10-K, filed with the Securities and Exchange Commission for the year ended December 31, 1995 and the Company's Quarterly Report on Form 10-Q, filed with the Securities and Exchange Commission for the quarter ended March 31, 1996. Results for any interim period are not necessarily indicative of results for any other interim period or for the entire year. 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES. REVENUE RECOGNITION UNDER DEVELOPMENT CONTRACTS. Non-refundable signing fees that are not dependent on future performance under collaborative agreements are recognized as revenue when received. Payments for research and development performed by the Company under contractual arrangements are recognized as revenue ratably over the quarter in which the payment is received and the related work is performed. Revenue from achievement of milestone events is recognized when the funding party agrees that the scientific or clinical results stipulated in the agreement have been met. Deferred revenue arises principally due to timing of cash payments received under research and development contracts. 6 7 NET LOSS PER SHARE. Net loss per share is computed using the weighted average number of shares of common stock outstanding. Common equivalent shares from options are excluded in the computation because their effect is anti-dilutive. MANAGEMENT ESTIMATES. The preparation of financial statements in conformity with generally accepted accounting principles requires the use of management's estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions could differ significantly from the amounts which may actually be realized. 7 8 ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS This Quarterly Report contains, in addition to historical information, forward-looking statements which involve risks and uncertainties. The Company's actual results may differ significantly from the results discussed in forward-looking statements. Factors that might cause such a difference include, but are not limited to those discussed in "Risk Factors" as well as those discussed elsewhere in this document and the Company's Annual Report on Form 10-K for the year ended December 31, 1995 and the Company's Quarterly Report on Form 10-Q for the period ended March 31, 1996. Overview Since the Company's founding in 1986, a primary focus of its operations has been research and development. Achievement of successful research and development and commercialization of products derived from such efforts is subject to high levels of risk and significant resource commitments. The Company has a history of operating losses and expects to incur substantial additional expenses over at least the next few years, as it continues to develop its proprietary products and devote significant resources to preclinical studies, clinical trials, and manufacturing. To date, revenues have been generated primarily by amounts earned under license agreements and interest income. These revenues may vary considerably from quarter to quarter and from year to year and revenues in any period may not be predictive of revenues in any subsequent period. The Company believes that increases in expenses in the coming years will exceed increases in non-royalty revenues under existing license agreements and that, as a result, in the absence of other sources of significant revenue, losses will increase from year to year. Three months ended June 30, 1996 and 1995 The Company's total revenues for the three months ended June 30, 1996 were approximately $5.0 million, an increase from approximately $4.1 million for the comparable period in 1995. Research and development revenues increased by $1.0 million and interest income approximately equaled the year-earlier quarter. The Company's research and development revenues under collaborative agreements primarily consist of up-front licensing and signing fees, research and development reimbursement funding and milestone payments. The amount of revenue, if any, earned from each of these components is expected to vary from quarter to quarter and from year to year, and variations may be significant depending on the terms of the particular agreements. Related party research and development revenues for the three months ended June 30, 1996 reflected amounts earned under the Company's joint development, marketing and licensing agreement with Boehringer Mannheim GmbH ("Boehringer Mannheim"), which increased by $0.5 million from the comparable period in 1995. This increase is attributable to increased efforts under the agreement by the Company. The Company expects that the current research and development 8 9 reimbursement funding arrangement with Boehringer Mannheim will expire as scheduled in October 1996. In addition, the Company earned research and development revenues of $0.5 million for the three months ended June 30, 1996 under the Company's development and licensing agreement with an unrelated third party compared to no revenues from unrelated third parties in the comparable period in 1995. Interest and other income for the three months ended June 30, 1996 in the amount of $1.5 million approximately equaled that in the comparable period of 1995. Although cash and investments were lower, interest rates for the three month period ended June 30, 1996 were higher than the comparable period in 1995. Total costs and expenses for the three months ended June 30, 1996 increased to approximately $8.5 million from approximately $6.5 million in the comparable period of 1995. The increase in costs and expenses was due primarily to increases in research and development efforts and related expenses. Research and development expenses for the three months ended June 30, 1996 increased to approximately $7.2 million from approximately $5.3 million in the comparable period of 1995, primarily as a result of the Company's conducting additional development efforts independently and under its agreements with its collaborative partner Boehringer Mannheim. These expenses included the continuation of clinical trials, costs of conducting preclinical tests, expansion of pharmaceutical development capabilities including support for both clinical development and manufacturing process development, higher costs in the expanded operation of the manufacturing facility and the addition of staff. The Company anticipates that expenses for research and development will continue to increase as its initial products move into later stage clinical development, as additional potential products are selected as clinical candidates for further development activities and as the Company expands its manufacturing capabilities in support of ongoing and planned clinical trials and potential commercial supplies. General and administrative expenses for the three months ended June 30, 1996 increased to approximately $1.3 million from approximately $1.2 million in the comparable period of 1995. These increases are primarily the result of increased staffing and associated expenses necessary to manage and support the Company's expanding operations. The Company believes that its general and administrative expenses will continue to increase as the Company increases its staffing, enhances its administrative capabilities and expands its patent activities. Six months ended June 30, 1996 and 1995 The Company's total revenues for the six months ended June 30, 1996 were approximately $10.6 million, an increase from approximately $8.2 million for the comparable period in 1995. Research and development revenues increased by approximately $2.4 million and interest income approximately equaled the year-earlier period. 9 10 Related party research and development revenues for the six months ended June 30, 1996 reflected amounts earned under the Company's agreement with Boehringer Mannheim, which increased by $2.0 million from the comparable period in 1995. This increase is attributable to increased efforts under the agreement by the Company as well as receipt of a milestone payment in January 1996. Increased funding from Boehringer Mannheim during the six months ended June 30, 1996 was partially offset by reduced funding from Hoffmann-La Roche Inc. and its parent Roche Holding Ltd. (collectively, "Roche"), which funding arrangement expired in January 1995. In addition, the Company earned research and development revenues of $0.5 million for the six months ended June 30, 1996 under the Company's development and licensing agreement with an unrelated third party compared to no revenues from unrelated third parties in the comparable period in 1995. Interest and other income for the six months ended June 30, 1996 in the amount of $3.1 million approximately equaled that in the comparable period of 1995. Although cash and investments were lower, interest rates for the six month period ended June 30, 1996 were higher than the comparable period in 1995. Total costs and expenses for the six months ended June 30, 1996 increased to approximately $16.3 million from approximately $12.1 million in the comparable period of 1995. The increase in costs and expenses was due primarily to increases in research and development efforts and related expenses. Research and development expenses for the six months ended June 30, 1996 increased to approximately $13.6 million from approximately $9.8 million in the comparable period of 1995, primarily as a result of the Company's conducting additional development efforts independently and under its agreements with its collaborative partner Boehringer Mannheim. These expenses included the continuation of clinical trials, costs of conducting preclinical tests, expansion of pharmaceutical development capabilities including support for both clinical development and manufacturing process development, higher costs in the expanded operation of the manufacturing facility and the addition of staff. The Company anticipates that expenses for research and development will continue to increase as its initial products move into later stage clinical development, as additional potential products are selected as clinical candidates for further development activities, as the Company expands its manufacturing capabilities in support of ongoing and planned clinical trials and potential commercial supplies. General and administrative expenses for the six months ended June 30, 1996 increased to approximately $2.6 million from approximately $2.3 million in the comparable period of 1995. These increases are primarily the result of increased staffing and associated expenses necessary to manage and support the Company's expanding operations. The Company believes that its general and administrative expenses will continue to increase as the Company increases its staffing, enhances its administrative capabilities and expands its patent activities. 10 11 The Company believes that total costs and expenses will rise significantly over the coming quarters and years as the Company continues to invest in research, pharmaceutical development, manufacturing, preclinical, and clinical activities and as additional potential products enter human clinical trials or progress to more advanced stages of clinical development. The Company believes that revenues from research and development reimbursement funding from Boehringer Mannheim will be essentially unchanged in 1996, compared to 1995. The Company expects that the current research and development reimbursement funding arrangement with Boehringer Mannheim will expire as scheduled in October 1996. The Company further believes that research and development revenues under existing agreements with collaborative partners will terminate or decline over time, as fewer milestones remain unearned, as products covered by such agreements proceed through clinical trials, and before such products receive marketing approval from appropriate authorities, if ever, and begin to generate royalty payments. Overall, the Company believes that increases in expenses over the next several years will more than offset any increases in non-royalty revenues under existing agreements. Liquidity and Capital Resources To date the Company has financed its operations primarily through public and private placements of equity, receipt of contract revenue and research and development funding under licensing agreements, capital lease financing and interest income on invested capital. At June 30, 1996, the Company had cash, cash equivalents and investments, both short and long term, in the aggregate of approximately $102.7 million as compared to approximately $107.1 million at December 31, 1995. The Company expects that its existing capital resources will enable the Company to maintain current and planned operations beyond 1997. Net cash used in operating activities was approximately $4.4 million for the six months ended June 30, 1996 compared to approximately $4.9 million in the comparable period of 1995. The Company expects to incur substantial additional costs in the future, including costs related to ongoing research and development activities, conducting preclinical and clinical trials, operation of its manufacturing facility and expansion of manufacturing capabilities, development of marketing and sales capabilities, increases in patent activities and continued expansion of general and administrative resources. These activities will require substantial additional financial resources before the Company can expect to realize significant revenue from product sales, if such revenues are ever achieved. There can be no assurance that additional funds will be available, when required on terms acceptable to the Company, if at all. Accounting Changes In October 1995, the Financial Accounting Standards Board ("FASB") issued Financial Accounting Standards No. 123 "Accounting for Stock Based Compensation" ("FAS 123") which will be effective for the Company's 1996 fiscal year. FAS 123 allows companies which have stock-based compensation arrangements with employees to 11 12 adopt a new fair-value basis of accounting for stock options and other equity instruments, or to continue to apply the existing accounting principles under APB Opinion 25, "Accounting for Stock Issued to Employees" but with additional financial statement disclosure. The Company expects to continue to account for stock-based compensation arrangements with employees under APB Opinion 25, and therefore does not expect FAS 123 to have a material impact on its financial position, results of operations and cash flows. 12 13 PART II.

RISK FACTORS This Quarterly Report contains forward-looking statements which involve risks and uncertainties. The Company's actual results may differ significantly from the results discussed in the forward-looking statements. Factors that might cause such a difference include, but are not limited to, those discussed in this section as well as those discussed elsewhere in this document and the Company's Annual Report on Form 10-K for the year ended December 31, 1995 and Quarterly Report on Form 10-Q for the Quarter ended March 31, 1996. History of Losses; Future Profitability Uncertain. As of June 30, 1996, the Company had accumulated net losses of approximately $29.4 million. To date, the Company has not received regulatory approval to distribute any products nor generated any significant revenues from product sales. The Company's research efforts have focused on the development of humanized and human antibodies and other novel proteins to prevent or treat certain disease conditions, including viral infections, autoimmune diseases, cancer and cardiovascular conditions. PDL's revenues to date have consisted, and for the near future are expected to consist, principally of research and development funding, licensing and signing fees and milestone payments from pharmaceutical companies under collaborative research and development agreements. No significant revenues have been generated from product sales or royalties from licenses to the Company's technology, and potential products that may be marketed by the Company, if any, are not expected to be approved for marketing for several years. The time and resource commitment required to achieve market success for any individual product is extensive and uncertain. No assurance can be given that the Company's or its collaborative partners' product development efforts will be successful, that required regulatory approvals can be obtained, that potential products can be manufactured at acceptable cost and with appropriate quality, or that any approved products can be successfully marketed. In the absence of revenues from new corporate collaborations or other sources, the Company expects to incur substantial operating losses in the foreseeable future as earlier stage products move into later stage clinical development, as additional potential products are selected as clinical candidates for further development and as the Company invests in additional manufacturing capacity. Moreover, the Company believes that its general and administrative expenses will continue to increase as the Company increases its staffing, enhances its administrative capabilities and expands its patent activities. The amount of net losses and the time required to reach sustained profitability are highly uncertain. To achieve sustained profitable operations, the Company, alone or with its collaborative partners, must successfully discover, develop, manufacture, introduce and market its products. No assurances can be given that the Company will be able to achieve or sustain profitability. 14 15 Uncertainty of Clinical Trial Results. Before obtaining regulatory approval for the commercial sale of any of its products under development, the Company must demonstrate through preclinical studies and clinical trials that the product is safe and efficacious for use in the clinical indication for which approval is sought. While the Company has certain preclinical and clinical evidence supporting further research and development of its potential products, there can be no assurance that the Company will be permitted to undertake further clinical trials for any of its products or, if permitted, that such products will be demonstrated to be safe and efficacious. The results from preclinical studies and early clinical trials may not be predictive of results that will be obtained in later-stage clinical trials and there can be no assurance that the Company's future clinical trials will demonstrate the safety and efficacy of any products or will result in approval to market products. In any particular situation numerous factors may be involved that may lead to different results in larger later-stage trials from those obtained in earlier stage trials. For example, early stage trials usually involve a small number of patients and thus may not accurately reflect the actual results regarding safety and efficacy that may be demonstrated with a large number of patients in a later-stage trial. Also, differences in the clinical trial design between an early-stage and late-stage trial may cause different results regarding the safety and efficacy of a product to be obtained. In addition, many early stage trials are unblinded and based on qualitative evaluations by clinicians involved in the performance of the trial whereas later stage trials are generally required to be blinded in order to provide more objective data for assessing the safety and efficacy of the product. The Company and a number of other companies in the biotechnology industry have suffered significant setbacks in advanced clinical trials, even after promising results in earlier-stage trials. For example, in June 1995, Roche and the Company announced the results of a Phase II/III clinical trial using the Company's SMART(TM) Anti-Tac Antibody, Zenapax, for the prevention of graft-versus-host disease. The analysis of this data by Roche led Roche to conclude that Zenapax was not effective in reducing the incidence of GvHD in the patient population studied. Roche is currently conducting two large, multinational Phase III trials of Zenapax for the reduction in the number of patients who experience kidney transplant rejection episodes within six months of transplantation. Enrollment has been completed and results are expected to be available in the third or fourth quarter of 1996. Although results of a Phase I trial in this indication were positive, the number of patients in that study was small and may not reflect the actual results that will be achieved when tested in a large number of patients. Moreover, no Phase II trial in this indication was conducted to obtain additional information about the use of Zenapax in patients prior to advancing to Phase III trials. Additionally, differences exist between the Phase I and Phase III trial designs, including, without limitation, the fact that most of the patients in the Phase I trial received kidney transplants from living related donors, whereas the Phase III trials only include patients who have received cadaverous transplants. Various factors, such as these, could lead to different results than those observed in the Phase I trial. Therefore, there can be no assurance that the results of the Phase III trials will be positive. If not, there would be a 15 16 material adverse effect on the Company's business and on the price of the Company's stock. PDL is also conducting potentially pivotal trials of its PROTOVIR(TM) human anti-CMV antibody, both for treatment of CMV retinitis in AIDS patients and for the prevention of CMV infections in recipients of bone marrow transplants. Earlier stage trials were limited to small numbers of patients and had significant differences in design from the larger Phase II and Phase II/III trials currently being conducted. For example, both the Phase II and the Phase II/III trial for the treatment of CMV retinitis will allow additional types of background treatment (i.e., the other drugs used to treat CMV retinitis) in the placebo and treatment groups than were available and used in the Phase I/II trial. These trials will also utilize a more sensitive means of measuring progression (i.e., relapse) of CMV retinitis than was used in the Phase I/II trial. These or other differences in trial designs between the later stage and earlier stage clinical trials might lead to different results regarding the safety and efficacy of PROTOVIR in these later stage trials. There can be no assurance that the results of these trials will show PROTOVIR to be safe and efficacious and, if not, there would be a material adverse effect on the Company's business and on the price of the Company's stock. Dependence on Collaborative Partners. The Company has collaborative agreements with several pharmaceutical companies for the development, manufacturing and marketing of certain potential products, which include the most advanced products under development by the Company. The Company has granted to its collaborative partners certain exclusive rights to commercialize the products developed under these collaborative agreements. In some cases, the Company is relying on its collaborative partners to conduct clinical trials, to obtain regulatory approvals and, if approved, to manufacture and market these licensed products. For example, Roche controls the development of Zenapax, the most advanced of the Company's products in development, and the Company is dependent upon the resources and activities of Roche to pursue further commercialization of Zenapax in order for the Company to achieve milestones or royalties from the development of this product. There can be no assurance that Roche will continue with additional or ongoing trials, that these trials will be successful or even if successful, that the results will be sufficient for regulatory approval, that Roche will proceed to bring this product to market in a rapid and timely manner, that Zenapax can be manufactured by Roche according to cGMP in a consistent and cost-effective manner or, once marketed, that other independently developed products of Roche or others will not compete with or prevent Zenapax from achieving meaningful sales. In addition, because the Company expects, in some cases, to rely on its contractual rights to access data collected by its collaborative partners in various phases of its clinical development efforts, the Company is dependent on the continued satisfaction by such parties of their contractual obligations to provide such access and cooperate with the Company in the preparation and submission of appropriate filings 16 17 with the FDA and equivalent foreign government regulatory agencies. For example, the Company is currently relying on and may continue to rely on Boehringer Mannheim for the manufacturing and clinical development of OST 577, the Company's Human Anti-Hepatitis B Virus Antibody. Boehringer Mannheim has marketing rights to this antibody in most countries, but not in North America. There can be no assurance that Boehringer Mannheim will provide timely access to the manufacturing and clinical data, that the FDA will permit the Company to rely on that data or that the trials conducted by Boehringer Mannheim will produce data appropriate for approval by the FDA. If the Company is unable to rely on the clinical data collected by Boehringer Mannheim or its other collaborative partners, the Company may be required to repeat clinical trials or perform supplemental clinical trials in order to achieve regulatory approval in North America. Compliance with these requirements could significantly delay commercialization efforts and require substantially greater investment by the Company. The Company's collaborative research agreements are generally terminable by its partners on short notice. Continued funding and participation by collaborative partners will depend not only on the timely achievement of research and development objectives by PDL and the successful achievement of clinical trial goals, neither of which can be assured, but also on each collaborative partner's own financial, competitive, marketing and strategic considerations. Such considerations include the commitment of management of the collaborative partners to the continued development of the licensed products, the relationships among the individuals responsible for the implementation and maintenance of the collaborative efforts, the relative advantages of alternative products being marketed or developed by others, including their relative patent and proprietary technology positions, and the ability to manufacture successfully. For example, with respect to its continuing relationship with Boehringer Mannheim, the Company has experienced difficulty in the relationship due to a number of factors, including disagreements regarding the timing of the initiation of and design of certain proposed clinical trials involving the development of certain products licensed to Boehringer Mannheim, particularly OST 577. In addition, certain collaborative partners may be developing competitive products that may result in delay or a relatively smaller resource commitment to product launch and support efforts than might otherwise be obtained if the potentially competitive product were not under development or being marketed. Suspension or termination of any of the Company's current collaborative research agreements could have a material adverse effect on the Company's operations and could significantly delay the development of the affected products. While the Company is seeking additional collaborative arrangements to develop and commercialize its products in the future, there can be no assurance it will be able to do so on acceptable terms. Limited Experience in, and Unpredictability of, Conducting Clinical Trials. Although certain of the officers and employees of the Company have significant previous experience in the pharmaceutical industry, the Company itself has conducted only a limited number clinical trials to date. There can be no assurance that the Company will be able to successfully commence and complete all of its planned clinical 17 18 trials without significant additional resources and expertise. In addition, there can be no assurance that the Company will meet its contemplated development schedule for any of its products in development. Certain of the Company's more advanced trials are being conducted with or by third party organizations, such as two trials of PROTOVIR, which are being conducted in collaboration with government-sponsored organizations. Certain of these relationships involve PDL surrendering significant control over some or all of the conduct of the clinical trial. There can be no assurance that surrendering or sharing control in certain of these trials will not result in delays due to factors such as changes in funding, reduction in the number of clinical sites participating in the trial or more limited patient accrual efforts than might otherwise be undertaken if PDL had sponsored the trial independently. If the Company or its collaborative partners are unable to commence or continue clinical trials as currently planned, complete the clinical trials on a timely basis or demonstrate the safety and efficacy of its potential products, the Company's business and financial condition would be materially and adversely affected. In addition, even if a potential product is successfully developed according to plans, there can be no assurance that the FDA or other regulatory authorities will approve the potential product on a timely basis or at all. The rate of completion of the Company's clinical trials is significantly dependent upon, among other factors, the rate of patient enrollment. Patient enrollment is a function of many factors, including the size of the patient population, perceived risks and benefits of the drug under study, availability of competing therapies, access to reimbursement from insurance companies, design of the protocol, proximity of and access by patients to clinical sites, patient referral practices, eligibility criteria for the study in question and efforts of the sponsor of and clinical sites involved in the trial to facilitate timely enrollment in the trial. Delays in the planned rate of patient enrollment may result in increased costs and expenses in completion of the trial or in potentially requiring the Company to undertake additional studies in order to obtain regulatory approval in the event that the applicable standard of care changes in the therapeutic indication under study. Any such delays or additional studies could have a material adverse effect on the business and financial condition of the Company. For example, the recent FDA approvals of Vitrasert(TM), a ganciclovir implant developed by Chiron Corporation to treat CMV retinitis, and VISTIDE(TM), a drug developed by Gilead Sciences, Inc., for the systemic treatment of CMV retinitis in patients with AIDS, may adversely impact the accrual of patients or the interpretation of the clinical data resulting from the current clinical trials of PROTOVIR. Also, patient accrual in the Company's ongoing Phase II/III trial of the SMART M195 Antibody in myeloid leukemia has been negatively affected by changes in referral patterns, with such patients now more commonly being treated in local hospitals rather than being referred to tertiary care hospitals. While the Company is exploring various possible actions to accelerate accrual in these trials, there can be no assurance that any such actions, if taken, will be successful. In addition, the Company is relying and intends to rely on CROs and other third parties under the management of the Company's clinical department for the conduct of clinical trials. There can be no assurance that PDL will be able to negotiate 18 19 arrangements with third parties for the conduct of PDL's clinical trials on acceptable terms in the future or that such arrangements will be successful. Uncertainties Resulting From Manufacturing Changes. Manufacturing of antibodies for use as therapeutics in compliance with regulatory requirements is typically complex, time-consuming and expensive. When certain changes are made in the manufacturing process, it is necessary to demonstrate that the changes have not caused the resulting drug material to differ significantly from the drug material previously produced (if results of prior preclinical and clinical studies performed using the previously produced drug material are to be relied upon in regulatory filings). Such changes could include, for example, changing the cell line used to produce the antibody, changing the fermentation or purification process or moving the production process to a new manufacturing plant. Depending upon the types and degree of differences between the newer and older drug material, various studies could be required to demonstrate that the newly produced drug material is sufficiently similar to the previously produced drug material, possibly including additional animal studies or human clinical trials. Manufacturing changes have been made or are likely to be made for the production of PDL's products currently in clinical development. There can be no assurance that such changes will not result in delays in development or regulatory approvals or, if occurring after regulatory approval, in reduction or interruption of commercial sales. Such delays could have an adverse effect on the competitive position of those products and could have a material adverse effect on the business and financial condition of the Company. Specifically, with respect to two of the antibodies in clinical development licensed from Sandoz, MSL 109 (PROTOVIR) and OST 577 (Human Anti-Hepatitis B Antibody), the cell lines developed by PDL for both antibodies and the production processes developed by PDL and Boehringer Mannheim for PROTOVIR and OST 577, respectively, are different from those utilized by Sandoz for the manufacture of the antibody supplies used in earlier clinical trials. With respect to the development of PROTOVIR, a decision to change the cell line and manufacturing procedure requires demonstration to the FDA that the new drug substance is acceptable. Although PDL has been permitted to enter new MSL 109 antibody material into ongoing U.S. clinical trials based on various laboratory tests, there can be no assurance that this new material, when used in humans, will have the same characteristics or produce results similar to the antibody material originally developed and used by Sandoz in earlier clinical trials. If not, the Company may be required to conduct additional laboratory or clinical testing, which could result in significant delays or additional expenses and could have an adverse effect on the competitive position of PROTOVIR and a material adverse effect on the business and financial condition of the Company. With respect to the development of OST 577, the Company has been advised that Boehringer Mannheim will be permitted to enter OST 577 manufactured by a new process into planned U.S. clinical trials. However, there can be no assurance that this new material, when used in humans, will have the same characteristics or produce 19 20 results similar to the antibody material originally developed and used by Sandoz in earlier clinical trials. If not, Boehringer Mannheim or the Company may be required to conduct additional laboratory or clinical testing, which could result in significant delays or additional expenses and could have an adverse effect on the competitive position of OST 577 and a material adverse effect on the business and financial condition of the Company. In addition, the Company is aware that Roche has constructed a new manufacturing plant that could be used to produce Zenapax. If Roche decides to change the site of its production of Zenapax to that or another facility or to make other manufacturing changes, then there can be no assurance that such changes by Roche would not cause delays in the development or commercialization of Zenapax. Such delays could have an adverse effect on the competitive position of Zenapax and could have a material adverse effect on the business and financial condition of the Company. Absence of Manufacturing Experience; Human Anti-HBV Antibody Manufacturing by Boehringer Mannheim. Of the products developed by the Company which are currently in clinical development, Roche is responsible for manufacturing Zenapax and Boehringer Mannheim is responsible for manufacturing OST 577. The Company intends to manufacture the SMART M195 Antibody, PROTOVIR and some of its other products in preclinical development. PDL currently leases approximately 45,000 square feet housing its manufacturing facility in Plymouth, Minnesota. PDL intends to continue to manufacture potential products for use in preclinical and clinical trials using this manufacturing facility in accordance with standard procedures that comply with cGMP and appropriate regulatory standards. The manufacture of sufficient quantities of antibody products in accordance with such standards is an expensive, time-consuming and complex process and is subject to a number of risks that could result in delays. Production delays, if they occur, could significantly delay clinical development of potential products, reduce third party or clinical researcher interest and support of proposed clinical trials, and possibly delay commercialization of such products and impair their competitive position. PDL has no experience in manufacturing commercial quantities of its potential products and currently does not have sufficient capacity to manufacture its potential products on a commercial scale. In order to obtain regulatory approvals and to expand its capacity to produce its products for commercial sale at an acceptable cost, PDL will need to improve and expand its existing manufacturing capabilities. PDL is evaluating plans to improve and expand the capacity of its current manufacturing facility. Such plans, if instituted, may require a suspension of manufacturing operations during construction. Moreover, there can be no assurance that construction delays would not occur and, if so, such delays could impair the Company's ability to produce adequate supplies of its potential products for clinical use or commercial sale on a timely basis. There can be no assurance that PDL will successfully improve and expand its manufacturing capability sufficiently to obtain necessary regulatory approvals and to 20 21 produce adequate commercial supplies of its potential products on a timely basis. Failure to do so could delay commercialization of such products and impair their competitive position and thus could have a material adverse effect on the Company. In addition, as part of the arrangement between PDL and Boehringer Mannheim, the parties have agreed to negotiate additional agreements in the future under which each company could manufacture and supply the other with certain of the antibodies covered by the agreement. There can be no assurance that the parties will enter into an agreement that will provide for the Company's potential product requirements to be met in a consistent, timely and cost effective manner. Specifically, with respect to OST 577, the Company currently does not manufacture this product internally and currently has no alternative manufacturing sources for this product. In the event that Boehringer Mannheim and the Company are unable to reach an acceptable agreement or if material is not supplied in accordance with such an agreement, there can be no assurance that the Company could make alternative manufacturing arrangements on a timely basis, if at all. 21 22 ITEM 6.
