7 REGENERON PHARMACEUTICALS, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except per share data) 1. INTERIM FINANCIAL STATEMENTS The interim Condensed Financial Statements of Regeneron Pharmaceuticals, Inc. ("Regeneron" or the "Company") have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information and disclosures necessary for a presentation of the Company's financial position, results of operations, and cash flows in conformity with generally accepted accounting principles. In the opinion of management, these financial statements reflect all adjustments, consisting only of normal recurring accruals, necessary for a fair presentation of the Company's financial position, results of operations, and cash flows for such periods. The results of operations for any interim periods are not necessarily indicative of the results for the full year. The December 31, 2000 Condensed Balance Sheet data was derived from audited financial statements, but does not include all disclosures required by generally accepted accounting principles. These financial statements should be read in conjunction with the financial statements and notes thereto contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2000. As discussed in Notes 2 and 13 below, the operating results for the three and six months ended June 30, 2000 have been restated from amounts previously reported to reflect the adoption of a new accounting principle for revenue recognition and reclassification of depreciation and amortization expense, respectively. 2. REVENUE RECOGNITION AND CHANGE IN ACCOUNTING PRINCIPLE During the fourth quarter of 2000, the Company changed its method of accounting for revenue recognition to conform with the guidance provided by Staff Accounting Bulletin No. 101, Revenue Recognition in Financial Statements ("SAB 101"). The change in accounting method was effective January 1, 2000 and, accordingly, the previously issued interim financial statements for the quarters ended March 31, June 30, and September 30, 2000 have been restated to reflect the adoption of SAB 101 as if it had occurred on January 1, 2000. The cumulative effect of adopting SAB 101 at January 1, 2000 amounted to $1,563 of additional loss as of that date, with a corresponding increase to deferred revenue to be recognized in subsequent periods. $186 of that deferred revenue, or $93 per quarter, is included in contract research and development revenue in both the six month period ended June 30, 2001 and 2000. The $1,563 represents a portion of a 1989 payment received from Sumitomo Chemical Company, Ltd. in consideration for a fifteen year limited right of first negotiation to license up to three of the Company's product candidates in Japan. The effect of income taxes on the cumulative effect adjustment was immaterial. 3. STATEMENT OF CASH FLOWS Supplemental disclosure of noncash investing and financing activities: Included in accounts payable and accrued expenses at June 30, 2001 and December 31, 2000 are $806 and $672, respectively, of accrued capital expenditures. Included in accounts payable and accrued expenses at June 30, 2000 and December 31, 1999 are $295 and $697, respectively, of accrued capital expenditures. 7

9 REGENERON PHARMACEUTICALS, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except per share data) 6. AMGEN-REGENERON PARTNERS RESEARCH COLLABORATION AGREEMENT In August 1990, the Company entered into a collaboration with Amgen Inc. ("Amgen") to develop and attempt to commercialize brain derived neurotrophic factor ("BDNF") and neurotrophin-3 ("NT-3") in the United States. Pursuant to that agreement, the Company and Amgen formed a partnership, Amgen-Regeneron Partners (the "Partnership"). The Company accounts for its investment in the Partnership in accordance with the equity method of accounting. In January 2001, the Partnership discontinued all clinical development of BDNF for the potential treatment of amyotrophic lateral sclerosis ("ALS") following notification that BDNF did not provide a therapeutic advantage to ALS patients in clinical trials. Selected operating statement data of the Partnership for the three and six months ended June 30, 2001 and 2000 is as follows: Three Months Ended June 30, Six Months Ended June 30, --------------------------- ------------------------- 2001 2000 2001 2000 ---- ---- ---- ---- Interest income $ 44 $ 86 $ 113 $ 164 Total expenses (537) (2,246) (2,707) (4,865) ----- ------- ------- ------- Net loss ($493) ($2,160) ($2,594) ($4,701) ===== ======= ======= ======= 7. COMPREHENSIVE LOSS Comprehensive loss represents the change in net assets of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Comprehensive loss of the Company includes net loss adjusted for the change in net unrealized gain or loss on marketable securities. The net effect of income taxes on comprehensive loss is immaterial. For the six months ended June 30, 2001 and 2000, the components of comprehensive loss are: Six Months Ended June 30, --------------------------- 2001 2000 ---- ---- Net loss ($27,871) ($11,642) Change in net unrealized gain on marketable securities 383 72 -------- -------- Total comprehensive loss ($27,488) ($11,570) ======== ======== 9

10 REGENERON PHARMACEUTICALS, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except per share data) 8. EQUITY TRANSACTIONS On March 23, 2001 the Company completed a public offering in which it issued 6.5 million shares of Common Stock at a price of $25.00 per share and received proceeds, after commissions and expenses, of $153.6 million. On April 11, 2001, the Company sold an additional 130,000 shares of Common Stock pursuant to the underwriters' over-allotment option from the March 2001 public offering at a price of $25.00 per share for proceeds to the Company, after commissions and expenses, of $3.1 million. In March 2001, Medtronic, Inc. exercised 107,400 warrants with an exercise price of $21.72 per share on a "cashless" basis and received 37,306 shares of the Company's Common Stock. 9. STOCK COMPENSATION The Company awards shares of Restricted Stock under the Regeneron Pharmaceuticals, Inc. Long-Term Incentive Plan. Restrictions on these shares lapse with respect to 25% of the shares every six months over a two-year period. In accordance with generally accepted accounting principles, the Company records unearned compensation in Stockholders' Equity related to these awards. The amount is based on the fair market value of shares of the Company's Common Stock on the date of the Restricted Stock award and is expensed, on a pro rata basis, over the two year period that the restrictions lapse. For the three and six months ended June 30, 2001, the Company recognized compensation expense related to Restricted Stock awards of $188 and $369, respectively. No stock-based compensation expense was recognized during 2000. 10

11 REGENERON PHARMACEUTICALS, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except per share data) 10. PER SHARE DATA The Company's basic net loss per share amounts have been computed by dividing net loss by the weighted average number of Common and Class A shares outstanding. For the three and six months ended June 30, 2001 and 2000, the Company reported net losses; therefore, no common stock equivalents were included in the computation of diluted net loss per share, since such inclusion would have been antidilutive. The calculations of basic and diluted net loss per share are as follows: Three Months Ended June 30, ------------------------------------------- Net Loss, in Shares, in thousands thousands Per Share (Numerator) (Denominator) Amount ------------ ------------- --------- 2001: Basic and Diluted ($14,834) 43,547 ($0.34) 2000: Basic and Diluted ($ 2,854) 34,971 ($0.08)

12 REGENERON PHARMACEUTICALS, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except per share data) 11. SEGMENT REPORTING The Company's operations are principally managed in two business segments: research and development, and contract manufacturing. Research and development: Includes all activities related to the discovery of potential therapeutics for human medical conditions, and the development and commercialization of these discoveries. Also includes revenues and expenses related to the development of manufacturing processes prior to commencing commercial production of a product under contract manufacturing arrangements. Contract manufacturing: Includes all revenues and expenses related to the commercial production of products under contract manufacturing arrangements. The Company produces an intermediate for a Merck & Co., Inc. pediatric vaccine under a long-term manufacturing agreement and, in 2000, produced BDNF for Sumitomo Pharmaceuticals Co., Ltd. under a research and development agreement. The tables below present information about reported segments for the three and six months ended June 30, 2001 and 2000: Three Months Ended June 30, 2001 ------------------------------------------------------------------ Research & Contract Reconciling Development Manufacturing Items Total ----------- ------------- ------------ --------- Revenues $ 3,118 $ 2,661 - $ 5,779 Loss in Amgen- Regeneron Partners 246 - - 246 Depreciation and amortization 1,419 -(2) - 1,419 Interest expense 31 12 - 43 Net (loss) income (19,138) 764 $ 3,540(1) (14,834) Capital expenditures 2,128 24 - 2,152 Three Months Ended June 30, 2000 ------------------------------------------------------------------ Research & Contract Reconciling Development Manufacturing Items Total ----------- ------------- ------------ --------- Revenues $ 11,931 $ 2,618 - $ 14,549 Loss in Amgen- Regeneron Partners 1,080 - - 1,080 Depreciation and amortization 1,045 -(2) - 1,045 Interest expense 78 25 - 103 Net (loss) income (6,393) 1,328 $ 2,211(1) (2,854) Capital expenditures 2,206 34 - 2,240 12

LITIGATION In September 2000, Immunex Corporation filed a request with the European Patent Office seeking the declaration of an Opposition regarding the scope of the Company's European patent relating to Cytokine Traps. This is a legal challenge to the validity and scope of the Company's patent. Although the Company plans to defend the patent diligently, the scope of the patent may be adversely affected following the outcome of the Opposition. In addition to this patent challenge, the Company, from time to time, has been subject to legal claims arising in connection with its business. While the ultimate results of the patent challenge and legal claims cannot be predicted with certainty, at June 30, 2001 there were no asserted claims against the Company which, in the opinion of management, if adversely decided would have a material adverse effect on the Company's financial position, results of operations, and cash flows. 13

14 REGENERON PHARMACEUTICALS, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except per share data) 13. RECLASSIFICATIONS Certain reclassifications have been made to the financial statements for the three and six months ended June 30, 2000 to conform with the current period's presentation. Effective in 2001, the Company's financial statement presentation of depreciation and amortization in the Statements of Operations has been changed to allocate depreciation and amortization between research and development expense and general and administrative expense. Depreciation and amortization related to contract manufacturing expense was already included in contract manufacturing expense in 2000. The effect of this reclassification for the three and six months ended June 30, 2000, for the three months ended September 30, 2000 and for the year ended December 31, 2000 is presented in the following table.

FUTURE IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS The Financial Accounting Standards Board has recently issued Statement of Financial Accounting Standards No. 141, Business Combinations and Statement of Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets, which the Company will be required to adopt in future periods. Management believes that the future adoption of these accounting standards will not have a material impact on the Company's financial statements. 14

15 ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS GENERAL OVERVIEW. The discussion below contains forward-looking statements that involve risks and uncertainties relating to the future financial performance of Regeneron Pharmaceuticals, Inc. and actual events or results may differ materially. These statements concern, among other things, the possible therapeutic applications of our product candidates and research programs, the timing and nature of the clinical and research programs now underway or planned, and the future uses of capital and our financial needs. These statements are made by us based on management's current beliefs and judgment. In evaluating such statements, stockholders and potential investors should specifically consider the various factors identified under the caption "Factors That May Affect Future Operating Results" which could cause actual results to differ materially from those indicated by such forward-looking statements. We do not undertake any obligation to update publicly any forward-looking statement, whether as a result of new information, future events, or otherwise, except as required by law. Regeneron Pharmaceuticals, Inc., which may be referred to as "we", "us", or "our", is a biopharmaceutical company that discovers, develops, and intends to commercialize therapeutic drugs for the treatment of serious medical conditions. Our product pipeline includes product candidates for the treatment of obesity, rheumatoid arthritis and other inflammatory conditions, cancer and related disorders, allergies, asthma, and other diseases and disorders. Since inception, we have not generated sales or any profits from the commercialization of any of our product candidates. Our core business strategy is to combine our strong foundation in science and technology with state-of-the-art manufacturing and clinical development capabilities to build a successful, integrated biopharmaceutical company. Our efforts have yielded a diverse and growing pipeline of product candidates that have the potential to address a variety of unmet medical needs. Our ability to develop product candidates results from the application of our technology platforms. In contrast to basic genomics approaches which attempt to identify every gene in a cell or genome, our technology platforms are designed to discover specific genes of therapeutic interest for a particular disease or cell type. We will continue to invest in the development of enabling technologies to assist in our efforts to identify, develop, and commercialize new product candidates. Below is a summary of our leading clinical programs, as well as several product candidates that are expected to enter clinical trials over the next two years. We retain sole ownership and marketing rights for each of these programs and currently are developing them independent of any corporate partners. 15

16 - AXOKINE(R): Acts on the brain region regulating food intake and energy expenditure and is being developed for the treatment of obesity. In November 2000, we announced the preliminary results of a twelve-week Phase II dose-ranging trial of AXOKINE in 170 severely obese patients. In the trial, AXOKINE was generally well tolerated and patients treated with AXOKINE showed medically meaningful and statistically significant weight loss compared to those receiving placebo. In July 2001, we reported that patients who completed 24 weeks of follow-up after cessation of treatment, on average, maintained the weight loss observed in the twelve-week treatment period. In July 2001, we initiated a Phase III program of testing AXOKINE in overweight and obese patients. The initial study will enroll approximately 2,000 patients in over 60 sites across the United States. - PEGYLATED AXOKINE: Chemically modified version of AXOKINE that is being developed as a more potent, longer-acting form of the protein. Pegylated AXOKINE currently is in late-stage preclinical development and we anticipate initiating a Phase I clinical trial in the second half of 2001. - INTERLEUKIN-1 CYTOKINE TRAP (IL-1 TRAP): Protein-based antagonist for the interleukin-1 (called IL-1) cytokine. IL-1 is thought to play a major role in rheumatoid arthritis and other inflammatory diseases. In December 2000, we initiated a Phase I study to assess the safety and tolerability of the IL-1 Trap in patients with rheumatoid arthritis. We expect the study to be completed in the second half of 2001. - INTERLEUKIN-4/INTERLEUKIN-13 CYTOKINE TRAP (IL-4/IL-13 TRAP): Protein-based antagonist for the interleukin-4 and interleukin-13 (called IL-4 and IL-13) cytokines which are thought to play a major role in diseases such as asthma, allergic disorders, and other inflammatory diseases. We expect to initiate a Phase I clinical trial of a dual IL-4/IL-13 Trap for asthma in late 2001. - VEGF TRAP: Protein-based antagonist to Vascular Endothelial Growth Factor (called VEGF, also known as Vascular Permeability Factor or VPF). VEGF is required for the growth of blood vessels that are needed for tumors to grow and is a potent regulator of vascular permeability and leak. The VEGF Trap is expected to enter a Phase I clinical trial in mid-2001. - ANGIOPOIETINS: A new family of growth factors that act specifically on the endothelium cells that line blood vessels. Angiopoietins may be useful for growing blood vessels in diseased hearts and other tissues with decreased blood flow and for repairing blood vessel leaks that cause swelling and edema in many different diseases such as stroke, diabetic retinopathy, and inflammatory diseases. Selected Angiopoietins, including engineered forms of these growth factors, are in preclinical development. 16

17 In addition to the above programs which we are conducting independent of any corporate partners, we have formed collaborations to advance other research and development efforts. We are conducting research with The Procter & Gamble Company in muscle diseases and other fields. We are also collaborating with Medarex, Inc. to discover, develop, and commercialize certain human antibodies as therapeutics. In partnership with Amgen Inc., we have development rights to Neurotrophin-3, or NT-3, for the treatment of constipating conditions. In all of these research collaborations, we retain 50% of the commercialization rights. DISCUSSION OF SECOND QUARTER 2001 ACTIVITIES In November 2000, we announced the preliminary results of a Phase II clinical trial, which tested the safety and efficacy of AXOKINE in severely obese patients. The Phase II trial was a randomized, double-blind, placebo-controlled, out-patient study conducted with 170 patients at seven sites in the United States. The trial established an optimal daily dose of AXOKINE of 1.0 mcg/kg. Patients who received the optimal dose over the twelve-week treatment period averaged 10 pounds more weight loss than patients on placebo. Moreover, 46% of the patients in the optimal dose group lost at least 10 pounds, compared to just 5% of the patients who received placebo. No serious adverse events associated with the drug were reported during the trial and the drug was generally well tolerated. In February 2001, we announced that based on a preliminary analysis of interim data, patients who received AXOKINE therapy during the Phase II study maintained their average weight loss during the twelve weeks following their last AXOKINE treatment, relative to patients who received placebo. In July 2001, we reported that patients who completed 24 weeks of follow-up after cessation of treatment, on average, maintained the weight loss observed in the twelve-week treatment period. In July 2001, we initiated a Phase III clinical program of AXOKINE in overweight and obese patients. The initial pivotal trial will enroll approximately 2,000 patients at over 60 study sites across the United States in a double-blind, randomized, placebo-controlled study. This trial will have a twelve-month treatment period, in which patients will receive daily subcutaneous self-injections of placebo or AXOKINE at a dose of 1.0 microgram (mcg) per kilogram (kg) of body weight. The treatment period will be followed by a twelve-month open-label safety extension phase, during which all patients will receive AXOKINE. Endpoints of the study are based on changes in body weight versus baseline during the treatment period. As part of the overall Phase III program, Regeneron will conduct additional confirmatory and ancillary studies of AXOKINE in obese and obese diabetic patients. These studies will vary in duration and size and are planned to be completed within the same time frame as the initial pivotal study described above. The Phase III program is expected to enroll approximately 4,000 subjects in total. Amgen-Regeneron Partners, the partnership equally owned by Amgen Inc. and us, has the development rights to NT-3 in the United States. In 2000, we, on behalf of Amgen-Regeneron Partners initiated Phase II studies of NT-3 in patients with functional constipation and spinal cord injury patients with bowel 17

18 dysfunction. We are currently evaluating preliminary data from these studies, and based in part on this data Amgen-Regeneron Partners will determine whether and how to proceed with the development of NT-3. A minority of all research and development programs ultimately results in commercially successful drugs; it is not possible to predict whether any program will succeed until it actually produces a drug that is commercially marketed for a significant period of time. In addition, in each of the areas of our independent and collaborative activities, other companies and entities are actively pursuing competitive paths toward similar objectives. The results of the Company's and its collaborators' past activities in connection with the research and development of AXOKINE, Cytokine Traps, Angiopoietins, cancer, abnormal bone growth, muscle atrophy, small molecules, NT-3, and other programs or areas of research or development do not necessarily predict the results or success of current or future activities including, but not limited to, any additional preclinical or clinical studies. We cannot predict whether, when, or under what conditions any of our research or product candidates, including without limitation AXOKINE, IL-1 Trap or NT-3, will be shown to be safe or effective to treat any human condition or be approved for marketing by any regulatory agency. The delay or failure of current or future studies to demonstrate the safety or efficacy of its product candidates to treat human conditions or to be approved for marketing could have a material adverse impact on Regeneron. We discuss the risks associated with drug development in the section of this report titled "Factors That May Affect Future Operating Results." We have not received revenue from the commercialization of our product candidates and may never receive such revenues. Before revenues from the commercialization of our product candidates can be realized, we (or our collaborators) must overcome a number of hurdles which include successfully completing our research and development efforts and obtaining regulatory approval from the FDA or regulatory authorities in other countries. In addition, the biotechnology and pharmaceutical industries are rapidly evolving and highly competitive, and new developments may render our products and technologies noncompetitive or obsolete. From inception on January 8, 1988 through June 30, 2001, we had a cumulative loss of $251.4 million. In the absence of revenues from the commercialization of our product candidates or other sources, the amount, timing, nature, or source of which cannot be predicted, our losses will continue as we conduct our research and development activities. Our activities may expand over time and may require additional resources and our operating losses may be substantial over at least the next several years. Our losses may fluctuate from quarter to quarter and will depend, among other factors, on the timing of certain expenses and on the progress of our research and development efforts. 18

19 RESULTS OF OPERATIONS Three months ended June 30, 2001 and 2000. Our total revenue decreased to $5.8 million for the second quarter of 2001 from $14.5 million for the same period in 2000. Contract research and development revenue decreased to $3.1 million in the second quarter of 2001 from $9.2 million for the same period in 2000. Under our long-term collaboration agreement with Procter & Gamble, research payments decreased effective in the first quarter of 2001 to $2.5 million per quarter versus $7.1 million for the same period of 2000. In addition, revenue from Amgen-Regeneron Partners decreased to $0.3 million for the second quarter of 2001 from $1.4 million for the same period in 2000 due primarily to the cessation of clinical trial activity on brain derived neurotrophic factor, or BDNF, in January 2001. In the second quarter of 2000, research progress payments consisted of a payment of $3.0 million (reduced by $0.3 million of Japanese withholding tax) from Sumitomo Pharmaceuticals related to the development of BDNF in Japan. Contract manufacturing revenue, related primarily to a long-term agreement with Merck & Co., Inc. (Merck) to manufacture a vaccine intermediate, was $2.7 million and $2.6 million for the second quarters of 2001 and 2000, respectively. Our total operating expenses increased to $23.9 million in the second quarter of 2001 from $18.4 million for the same period in 2000. Research and development expenses increased to $19.6 million in the second quarter of 2001 from $15.4 million for the same period in 2000, primarily as a result of higher staffing and increased activity in our preclinical and clinical research programs. Research and development expenses were 82% of total operating expenses in the second quarter of 2001, compared to 84% for the same period in 2000. Contract manufacturing expenses increased to $1.9 million in the second quarter of 2001 from $1.3 million for the same period in 2000 due primarily to higher costs associated with commercial production under our long-term agreement with Merck. General and administrative expenses increased to $2.4 million in the second quarter of 2001 from $1.7 million for the same period of 2000, due primarily to higher administrative staffing and related occupancy costs. Investment income increased to $3.5 million for the second quarter of 2001 from $2.2 million for the same period in 2000 due to interest earned on the proceeds of our public offerings in March 2001 and April 2000 and our sale of Common Stock to Procter & Gamble in August 2000. The loss in Amgen-Regeneron Partners decreased to $0.2 million for the second quarter of 2001 from $1.1 million for the same period in 2000 due primarily to the cessation of clinical trial activity on BDNF in January 2001. The Company's net loss for the second quarter of 2001 was $14.8 million, or $0.34 per share (basic and diluted), compared to a net loss of $2.9 million, or $0.08 per share (basic and diluted), for the same period in 2000. Six months ended June 30, 2001 and 2000. Our total revenue decreased to $12.1 million for the six months ended June 30, 2001 from $25.1 million for the same period in 2000, as higher contract manufacturing revenue was more than offset by decreases in contract research and development revenue and research progress payments. Contract 19

20 research and development revenue decreased to $6.5 million for the six months ended June 30, 2001 from $18.4 million for the same period in 2000. Under our long-term collaboration agreement with Procter & Gamble, research payments decreased effective in the first quarter of 2001 to $2.5 million per quarter from $7.1 million per quarter for the first two quarters of 2000. In addition, revenue from Amgen-Regeneron Partners decreased to $1.0 million for the six months ended June 30, 2001 from $3.3 million for the same period in 2000 due primarily to the cessation of clinical trial activity on BDNF in January 2001. In the first half of 2000, research progress payments consisted of a payment of $3.0 million (reduced by $0.3 million of Japanese withholding tax) from Sumitomo Pharmaceuticals related to the development of BDNF in Japan. Contract manufacturing revenue, related primarily to our long-term agreement with Merck to manufacture a vaccine intermediate, increased to $5.6 million in the first half of 2001 from $4.0 million for the same period in 2000, due to an increase in the revenue we received per shipment of intermediate to Merck during the first six months of 2001. Our total operating expenses increased to $44.9 million for the six months ended June 30, 2001 from $36.1 million for the same period in 2000. Research and development expenses increased to $36.4 million in the first six months of 2001 from $28.3 million for the same period in 2000, primarily as a result of higher staffing and increased activity in our preclinical and clinical research programs. Research and development expenses were 81% of total operating expenses for the first six months of 2001, compared to 78% for the same period in 2000. Contract manufacturing expenses decreased to $4.1 million in the first half of 2001 from $4.3 million for the same period in 2000 due, in part, to higher costs in the first quarter of 2000 associated with initiating commercial production at our Rensselaer, New York facility of both vaccine intermediate for Merck and BDNF for clinical use by Sumitomo Pharmaceuticals. We stopped producing clinical supplies of BDNF for Sumitomo Pharmaceuticals at the end of 2000. General and administrative expenses increased to $4.4 million in the first six months of 2001 from $3.5 million for the same period of 2000, due primarily to higher administrative staffing and related occupancy costs. Investment income increased to $6.3 million for the six months ended June 30, 2001 from $3.4 million for the same period in 2000 due to interest earned on the proceeds of our public offerings in March 2001 and April 2000 and our sale of Common Stock to Procter & Gamble in August 2000. The loss in Amgen-Regeneron Partners decreased to $1.3 million for the first half of 2001 from $2.4 million for the same period in 2000 due primarily to the cessation of clinical trial activity on BDNF in January 2001. During the fourth quarter of 2000, we changed our method of accounting for revenue recognition to conform with the guidance provided by Staff Accounting Bulletin No. 101, Revenue Recognition in Financial Statements, (SAB 101). The change in accounting method was effective January 1, 2000 and, as a result, we restated the previously issued interim financial statements for the six months ended June 30, 2000 to reflect the adoption of SAB 101 as if it had occurred on January 1, 2000. The cumulative effect of adopting SAB 101 as of January 1, 2000 was to increase our net loss by $1.6 million as of that date, or $0.05 per share, with a corresponding increase to deferred 20

21 revenue to be recognized in subsequent periods. The SAB 101 adjustment relates to a portion of a 1989 payment received from Sumitomo Chemical Company, Ltd. in consideration for a fifteen year limited right of first negotiation to license up to three of our product candidates in Japan. In the first half of both 2001 and 2000, we recognized contract research and development revenue of $0.2 million that was included in the cumulative effect adjustment as of January 1, 2000. The Company's net loss for the six months ended June 30, 2001 was $27.9 million, or $0.69 per share (basic and diluted), compared to a net loss of $11.6 million, or $0.35 per share (basic and diluted), for the same period in 2000. LIQUIDITY AND CAPITAL RESOURCES Since our inception in 1988, we have financed our operations primarily through private placements and public offerings of our equity securities, revenue earned under our agreements with Amgen, Sumitomo Chemical, Sumitomo Pharmaceuticals, Merck, and Procter & Gamble, and investment income. In May 1997, we entered into a long-term collaboration agreement with Procter and Gamble. Procter & Gamble agreed over the first five years of the 1997 collaboration to purchase up to $60.0 million in Regeneron equity, of which $42.9 million was purchased in June 1997 and $17.1 million was purchased in August 2000, and provide funding in support of our research efforts related to the collaboration, of which we have received $54.2 million through June 30, 2001. In August 2000, Procter & Gamble made two non-recurring research progress payments to us totaling $3.5 million. In addition, in August 2000, we and Procter & Gamble signed a binding memorandum of understanding that resulted in a new long-term collaboration agreement, replacing the companies' 1997 agreement, effective as of December 31, 2000. The new agreement extends Procter & Gamble's obligation to fund Regeneron's research through December 2005, with no further research obligations by either party thereafter, and focuses the companies' collaborative research on therapeutic areas that are of particular interest to Procter & Gamble. Under the new agreement, beginning in the first quarter of 2001, research support from Procter & Gamble is $2.5 million per quarter, before adjustments for future inflation, through December 2005. Our activities relating to BDNF and NT-3, as agreed upon by Amgen and us, are being compensated by Amgen-Regeneron Partners for services rendered, and we recognize these amounts as revenue. In January 2001, Amgen-Regeneron Partners discontinued all development of BDNF for the potential treatment of amyotrophic lateral sclerosis, or ALS. We and Amgen fund Amgen-Regeneron Partners through capital contributions, and must make equal payments in order to maintain equal ownership and equal sharing of any profits or losses from the partnership. Our aggregate capital contribution to Amgen-Regeneron Partners from the partnership's inception in June 1993 through June 30, 2001 was $57.4 million. We expect that our capital contributions for the remainder of 2001 will total at least $1.1 million. These contributions could increase or decrease, depending upon, among other things, the nature and cost of any additional NT-3 studies that Amgen-Regeneron Partners may conduct. 21

22 In connection with our agreement to collaborate with Sumitomo Pharmaceuticals in the research and development of BDNF in Japan, we received a research progress payment from Sumitomo Pharmaceuticals of $3.0 million (reduced by $0.3 million Japanese withholding tax) in April 2000. In addition, Sumitomo Pharmaceuticals has paid us $31.6 million through June 30, 2001 in connection with supplying BDNF for preclinical and clinical use. In light of the discontinuation of BDNF development for ALS, we do not expect to receive further payments from Sumitomo Pharmaceuticals for research progress payments, contract research and development, or contract manufacturing, other than amounts outstanding and any wind-down costs. Our additions to property, plant, and equipment for the six months ended June 30, 2001 and 2000 totaled $4.0 million and $3.9 million, respectively. In connection with the purchase and renovation of our Rensselaer facility, we obtained financing of $2.0 million from the New York State Urban Development Corporation in 1994, of which $1.5 million is outstanding. Under the terms of this UDC financing, we are not permitted to declare or pay dividends on our equity securities. We expect that expenses related to the filing, prosecution, defense, and enforcement of patent and other intellectual property claims will continue to be substantial as a result of patent filings and prosecutions in the United States and foreign countries. In September 2000, Immunex Corporation filed a request with the European Patent Office seeking the declaration of an Opposition regarding our European patent relating to Cytokine Traps. This is a legal challenge to the validity and scope of our patent and we may incur substantial expenses in defending the patent. As of June 30, 2001, we had no established banking arrangements through which we could obtain short-term financing or a line of credit. We may seek additional funding through, among other things, future collaboration agreements and public or private financing. We cannot assure you that additional financing will be available to us or, if available, that it will be available on acceptable terms. In April 2000, we completed a public offering of 2.6 million shares of Common Stock at a price of $29.75 per share and received proceeds, after commissions and expenses, of $72.9 million. In August 2000, we sold 573,630 shares of Common Stock to Procter & Gamble at a price of $29.75 per share and received total proceeds of $17.1 million. The sale of stock to Procter & Gamble was made pursuant to a 1997 securities purchase agreement. In March 2001, we completed a public offering in which we issued 6.5 million shares of Common Stock at a price of $25.00 per share and received proceeds, after commissions and expenses, of $153.6 million. In April 2001, we sold an additional 130,000 shares of Common Stock pursuant to the underwriters' over-allotment option from the March 2001 public offering at a price of $25.00 per share and received proceeds, after commissions and expenses, of $3.1 million. At June 30, 2001, we had $290.5 million in cash, cash equivalents, and marketable securities. We expect to incur substantial funding requirements for, among other things, research and development activities (including preclinical and clinical testing), expansion and validation of manufacturing facilities, and the acquisition of 22

23 equipment. We currently anticipate that for the remainder of 2001 and 2002, approximately 50-70% of our expenditures will be directed toward the preclinical and clinical development of product candidates, including AXOKINE, Pegylated AXOKINE, IL-1 Trap, IL-4/13 Trap, VEGF Trap, and the Angiopoietins; approximately 10-30% of our expenditures will cover our basic research activities; approximately 5-15% of our expenditures will be directed toward the continued development of our novel technology platforms, including potential efforts to commercialize these technologies; and the remainder of our expenditures will be for general corporate purposes, including working capital. The amount we need to fund operations and the allocation of our resources will depend on various factors, including the status of competitive products, the success of our research and development programs, the potential future need to expand our professional and support staff and facilities, the status of patents and other intellectual property rights, the delay or failure of a clinical trial of any of our potential drug candidates, and the continuation, extent, and success of any collaborative research arrangements (including those with Procter & Gamble, Medarex, Emisphere Technologies, Inc., and Amgen). We believe that our existing capital resources will enable us to meet operating needs through at least 2002. However, this is a forward-looking statement based on our current operating plan, and we cannot assure you that there will be no change in projected revenues or expenses that would lead to our capital being consumed significantly before such time. If there is insufficient capital to fund all of our planned operations and activities, we believe we would prioritize available capital to fund preclinical and clinical development of our product candidates. FUTURE IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS The Financial Accounting Standards Board has recently issued Statement of Financial Accounting Standards No. 141, Business Combinations and Statement of Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets, which the Company will be required to adopt in future periods. Management believes that the future adoption of these accounting standards will not have a material impact on the Company's financial statements. FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS We caution shareholders and potential investors that the following important factors, among others, in some cases have affected, and in the future could affect, our actual results and could cause our actual results to differ materially from those expressed in any forward-looking statements made by, or on behalf of, us. The statements under this caption are intended to serve as cautionary statements within the meaning of the Private Securities Litigation Reform Act of 1995. The following information is not intended to limit in any way the characterization of other statements or information under other captions as cautionary statements for such purpose: - Delay, difficulty, or failure of our research and development programs to produce product candidates that are scientifically or commercially appropriate for further development by us or others. 23

24 - Cancellation or termination of material collaborative or licensing agreements (including in particular, but not limited to, those with Procter & Gamble and Amgen) and the resulting loss of research or other funding could have a material adverse effect on us and our operations. A change of control of one or more of our material collaborators or licensees could also have a material adverse effect on us. - Delay, difficulty, or failure of a clinical trial of any of our product candidates. A clinical trial can fail or be delayed as a result of many causes, including, among others, failure of the product candidate to demonstrate safety or efficacy, the development of serious or life-threatening adverse events (side effects) caused by or connected with exposure to the product candidate, difficulty in enrolling and maintaining patients, lack of sufficient supplies of the product candidate, and the failure of clinical investigators, trial monitors and other consultants, or trial subjects to comply with the trial plan or protocol. - In addition to the safety, efficacy, manufacturing, and regulatory hurdles faced by our drug candidates, the administration of recombinant proteins frequently causes an immune response, resulting in the creation of antibodies against the therapeutic protein. The antibodies can have no effect or can totally neutralize the effectiveness of the protein, or require that higher doses be used to obtain a therapeutic effect. In some cases, the antibody can cross react with the patient's own proteins, resulting in an "auto-immune type" disease. Whether antibodies will be created can often not be predicted from preclinical experiments and their appearance is often delayed, so that there can be no assurance that neutralizing antibodies will not be created at a later date -- in some cases even after pivotal clinical trials have been successfully completed.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK. Our earnings and cash flows are subject to fluctuations due to changes in interest rates primarily from our investment of available cash balances in investment grade corporate and U.S. government securities. We do not believe we are materially exposed to changes in interest rates. Under our current policies we do not use interest rate derivative instruments to manage exposure to interest rate changes. 26
