CELGENE CORPORATION

Notes to Unaudited Consolidated Financial Statements September 30, 2002

1. Basis of Presentation

The unaudited consolidated financial statements have been prepared from the books and records of Celgene Corporation and subsidiaries ("Celgene" or the "Company") in accordance with accounting principles generally accepted in the United States of America for interim financial information pursuant to Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required for complete annual financial statements.

In the opinion of management, all adjustments (consisting only of normal recurring accruals) considered necessary for a fair presentation have been included. Interim results may not be indicative of the results that may be expected for the year. Certain adjustments and reclassifications were made to conform to the current year presentation.

The interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's latest annual report on Form 10K.

2. Earnings per Share

"Basic" earnings (loss) per common share equals net income (loss) divided by weighted average common shares outstanding during the period. The Company's basic and diluted per share amounts for the three and nine month periods ended September 30, 2002 and 2001 are the same since the assumed exercise of stock options and warrants, and the conversion of convertible notes, the last of which were converted in June 2002, are all anti-dilutive because of the loss incurred by the Company during these periods. The amount of common stock equivalents excluded from the calculation were 9,768,103 at September 30, 2002 and 10,378,710 at September 30, 2001.

3. New Accounting Pronouncement

In July 2002, the Financial Accounting Standards Board ("FASB") issued FAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities. This Standard supercedes the accounting guidance provided by Emerging Issues Task Force Issue No. 94-3, Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring). FAS No. 146 requires companies to recognize costs associated with exit activities when they are incurred rather than at the date of a commitment to an exit or disposal plan. FAS No. 146 is effective for exit or disposal activities initiated after December 31, 2002; early application is encouraged. The Company is currently evaluating this Standard.

4. Research Collaboration and Investment

The Company has two collaborative research agreements with Anthrogenesis Corp., a privately held biotechnology company focused on stem cell commercialization and research, designed to evaluate the application of Celgene's product pipeline in the stem cell therapy field. During the second quarter, Celgene and Anthrogenesis Corp. entered into a purchase option agreement. In addition, Celgene signed an agreement with Anthrogenesis to invest $6 million in the form of notes which would be convertible into common stock if the purchase option agreement was not executed. The notes would be convertible at the option of Anthrogenesis except that at no time can the conversion result in an ownership by Celgene of more than 19.9%. The initial conversion rate is $8.035 and is subject to adjustment. The notes have a term of three years and bear interest at the prime rate plus 2%. The agreement was amended in September 2002 to provide for a total investment in convertible notes of $11.0 million. The investment secures an option for Celgene to purchase all the outstanding shares of Anthrogenesis Corp. In September 2002, the respective Boards of Directors of Celgene and Anthrogenesis approved a plan of merger. Celgene will issue common shares at a minimum exchange ratio of .4545 of a share of Celgene common stock for each share of Anthrogenesis common stock, and stock options and warrants at the same exchange ratio for each outstanding Anthrogenesis stock option and warrant. Based on this exchange ratio and the Anthrogenesis common stock, options and warrants outstanding at November 11, 2002, Celgene will issue approximately 1.5 million shares of common stock and approximately 1.2 million stock options and warrants. Should Anthrogenesis achieve certain performance objectives prior to closing, the exchange ratio could be adjusted by approximately 10%. Completion of the merger, which is subject to certain conditions, is anticipated by year end. As of September 30, 2002, $8.5 million in convertible notes and $0.5 million in research funding has been provided to Anthrogenesis. Anthrogenesis is considered a related party as a senior executive of the Company serves on the Board of Directors of Anthrogenesis.

7. Convertible Notes

On January 20, 1999, the Company issued to an institutional investor convertible notes in the amount of $15,000,000. The notes had a five year term and a coupon rate of 9% with interest payable on a semi-annual basis. The notes contained a conversion feature that allowed the note holders to convert the notes into common shares after one year at $6 per share. During 2000, $13,286,400 of the notes were converted into 2,214,399 common shares. During June 2002, the remaining notes, having a carrying value of $1,713,600, were converted into 285,601 common shares.

On July 6, 1999, the Company issued to the same institutional investor convertible notes in the amount of $15,000,000. The notes had a five year term and a coupon rate of 9% with interest payable on a semi-annual basis. The notes contained a conversion feature that allowed the note holders to convert the notes into common shares after one year at $6.33 per share. During 2000, $5,000,000 of the notes were converted to 789,474 common shares. During June 2002, the remaining notes, having a carrying value of $10,000,000, were converted into 1,578,948 common shares.

9. Stockholders' Equity

Warrants to Acquire Common Stock

Under the terms of a private placement of Series B Preferred Stock entered into on June 9, 1997, the Company was obligated to issue warrants to acquire a number of shares of common stock. As of December 31, 2001, 967,693 warrants remained outstanding and were exercisable at $2.49 per share. During the second quarter of 2002, all the outstanding warrants were exercised and converted into common shares.

Deferred Compensation Expense

Prior to the Company's merger with Signal Pharmaceuticals, Inc., Signal recorded an aggregate of approximately $9.4 million of deferred compensation for stock options granted from 1997 through 2000, representing the difference between the option exercise price and the estimated fair value of the underlying stock for financial statement presentation purposes. The deferred compensation is being amortized over the vesting period of the options. Through September 30, 2002, the Company has recorded approximately $8.0 million of compensation expense of which approximately $311,000 and $600,000 was recorded during the three month periods ended September 30, 2002 and 2001, respectively and approximately $1.1 million and $1.9 million was recorded during the nine month period ended September 30, 2002 and 2001, respectively. Upon the termination of certain employees and consultants, the Company reversed approximately $1.1 million of unamortized deferred compensation relating to their unvested options through September 2002.

The Company recorded compensation expense relating to stock options and warrants issued to consultants, advisors or financial institutions and other stock-based compensation of approximately $138,000 and $165,000 for the three month periods ended September 30, 2002 and 2001, respectively and approximately $274,000 and $762,000 for the nine month periods ended September 30, 2002 and 2001, respectively.

10. Subsequent Event

In October 2002, the Company entered into a co-promotion agreement with Cell Pathways, Inc. to market and sell Cell Pathway's product, Gelclair(TM) through Celgene's salesforce. Gelclair is used in the treatment of mucositis, a common side effect of radiation and chemotherapy regimens used in treating various cancers. Celgene will receive a percent of the net sales of the product as defined in the agreement.

PART 1 -- FINANCIAL INFORMATION

ITEM 2 -- MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

Results of Operations

Three month period ended September 30, 2002 vs. Three month period ended September 30, 2001

Total revenue: Our total revenue for the three months ended September 30, 2002 increased approximately 31% to $34.3 million compared to $26.2 million in the same period of 2001. Revenue in 2002 consisted of THALOMID(R) sales of $30.5 million, Focalin(TM) sales of $0.4 million, Ritalin(R) product royalties of $1.8 million, and other collaborative agreements revenue of $1.6 million compared to THALOMID(R) sales of $21.7 million, collaborative agreements revenue of $3.9 million and related-party revenue of $0.6 million in the same period of 2001. Increasing use of THALOMID(R) by oncologists in the treatment of various types of cancer contributed to the 42% growth in product sales. The decrease in collaborative agreements revenue is primarily attributable to the completion of the amortization in November 2001 of the up-front payment from Novartis Pharma AG related to the license agreement on Focalin(TM). Related-party revenue declined in 2002 as a result of the initial term of our agreement with Axys Inc. ending in October 2001. The agreement has not been extended.

Cost of goods sold: Cost of goods sold during the three months ended September 30, 2002 was $4.4 million or 14.5% as a percent of product sales compared with approximately $3.2 million or 14.9% as a percent of product sales in the comparable period in 2001. The decrease in cost of goods sold as a percent of product sales is attributable to more favorable quality control and quality assurance costs and lower freight costs related to THALOMID sales. Cost of goods sold for the third quarter of 2002 relating to Focalin(TM) sales was lower than the normal cost at standard as some manufacturing costs incurred prior to Focalin's(TM) approval in November 2001 were expensed as research and development expenses. This favorable treatment will continue until the cost associated with the quantity previously expensed is completely sold.

Research and development expenses: Research and development expenses consist primarily of salaries and benefits, contractor fees, principally with contract research organizations to assist in our clinical development programs, clinical drug supplies for our clinical and preclinical programs as well as other consumable research supplies, and allocated facilities charges such as building rent and utilities. Research and development expenses for the third

13

quarter of 2002 increased 12% to $20.5 million from $18.4 million in 2001. During the third quarter of 2002, approximately $12.2 million was spent on THALOMID(R) and the IMiDs(R) and SelCIDs(TM), primarily for preclinical toxicology, phase I/II and phase III clinical trials and regulatory expenses. We spent approximately $8.3 million in our gene regulation, target discovery and agro-chemical programs, primarily for internal headcount related expenses, laboratory supplies and product development costs.
As a percent of total revenue, research and development expenses were approximately 60% and 70% for the three month periods ended September 30, 2002 and 2001, respectively. As a result of increasing revenue, research and development expenses may continue to decrease as a percent of total revenue although the actual dollar amount will continue to increase as we move our earlier stage compounds through preclinical and clinical programs. In general, time to completion of each phase would be as follows:

Phase I -----  1-2 years
Phase II ----  2-3 years
Phase III ---  2-3 years

Due to the significant risks and uncertainties inherent in preclinical tests and clinical trials associated with each of our research and development projects, the cost to complete such projects is not reasonably estimable. The data obtained from these tests and trials may be susceptible to varying interpretation that could delay, limit or prevent a project's advancement through the various stages of clinical development, which would significantly impact the costs incurred to bring a project to completion.

Selling, general and administrative expenses: Selling expenses consist of salaries and benefits for sales and marketing and customer service personnel, warehousing and distribution costs, and other commercial expenses to support the sales force and the education and registration efforts underlying the S.T.E.P.S.(R) (System for Thalidomide Education and Prescribing Safety) program. The S.T.E.P.S.(R) program requires that all physicians prescribing THALOMID(R), all pharmacies dispensing THALOMID(R) and all patients being treated with THALOMID(R) must be included in a registry. Inclusion in the registry in turn ensures that the physicians, pharmacists and patients have participated in the education program for the safe and appropriate use of THALOMID(R).

14

General and administrative expenses consist primarily of salaries and benefits, outside services for legal, audit, tax and investor activities and allocations of facilities costs, principally for rent, utilities and property taxes. Selling, general and administrative expenses decreased by approximately 6% for the three months ended September 30, 2002 to $15.7 million from $16.7 million in the same period in 2001. The decrease was due primarily to expenses associated with the education, registration and validation required for the rollout of the enhanced S.T.E.P.S.(R) system in September of 2001.

Interest and other income and expense: Interest and other income for the third quarter of 2002 decreased approximately 7% to approximately $5.4 million from $5.8 million in the same period in 2001. The decrease was primarily due to lower interest income due to lower interest rates and lower balances of marketable securities offset by an increase in realized gains on the sale of securities in the third quarter of 2002.

Interest expense for the third quarter of 2002 decreased to approximately $11,000 from approximately $23,000 in the same period in 2001. The decrease was due primarily to the expiration of a three year capital equipment lease in July 2001.

Net income (loss): We recorded a net loss of $1.0 million in the three month period ended September 30, 2002 compared to a loss of $6.3 million in the same period in 2001. The decreased loss was due to increased revenue of $8.1 million offset by the increase in costs and expenses of $2.4 million and the decrease in interest and other income of $0.4 million.

Nine month period ended September 30, 2002 vs. Nine month period ended September 30, 2001

Total revenue: Our total revenue for the nine months ended September 30, 2002 increased 36% to $98.6 million compared with $72.5 million in the same period of 2001. Revenue in 2002 consisted of THALOMID(R) sales of $85.1 million, Focalin(TM) sales of $3.8 million, Ritalin(R) product royalties of $3.2 million and other collaborative agreements revenue of $6.4 million compared with THALOMID(R) sales of $57.4 million, collaborative agreements revenue of $13.2 million and related-party revenue of $1.9 million in the same period of 2001.

15

Increasing use of THALOMID(R) by oncologists in the treatment of various types of cancer, especially in multiple myeloma, as well as the $3.8 million of Focalin(TM) sales in 2002, contributed to the 55% growth in product sales. The decrease in collaborative agreements revenue is primarily attributable to the completion of the amortization in November 2001 of the up-front payment on a research agreement with Novartis Pharma AG. Related-party revenue declined in 2002 as a result of the initial term of our agreement with Axys Inc. ending in October 2001. The agreement has not been extended.

Cost of goods sold: Cost of goods sold during the first nine months of 2002 was $12.2 million or 13.7% as a percent of product sales compared with approximately $8.8 million or 15.3% as a percent of product sales in the comparable period in 2001. The decrease in cost of goods sold as a percent of product sales is attributable to more favorable quality control and quality assurance costs and lower freight costs related to THALOMID(R) sales. Cost of goods sold for the first nine months of 2002 relating to Focalin(TM) sales was lower than the normal cost at standard as some manufacturing costs incurred prior to Focalin's(TM) approval in November 2001 were expensed as research and development expenses. This favorable treatment will continue until the cost associated with the quantity previously expensed is completely sold.

Research and development expenses: Research and development expenses increased by 22% for the nine months ended September 30, 2002 to $57.6 million from $47.3 million in the same period in 2001. During the first nine months of 2002, approximately $32.9 million was spent on THALOMID(R) and the IMiDs(R) and SelCIDs(TM), primarily for preclinical toxicology, phase I/II and phase III clinical trials and regulatory expenses. We spent approximately $24.7 million in our gene regulation, target discovery and agro-chemical programs, primarily for internal headcount related expenses, laboratory supplies and product development costs.
As a percent of total revenue, research and development expenses were approximately 58% and 65% for the nine months ended September 30, 2002 and 2001, respectively. As a result of increasing revenue, research and development expenses may continue to decrease as a percent of total revenue although the actual dollar amount will continue to increase as we move our earlier stage compounds through preclinical and clinical programs.

16

Selling, general and administrative expenses: Selling, general and administrative expenses increased by 22% for the nine months ended September 30, 2002 to $50.2 million from $41.1 million in the same period in 2001. The increase was due primarily to the expansion of the sales and marketing organization and related expenses, an increase in customer service staff as well as expenses related to a new customer service and enhanced S.T.E.P.S.(R) system (System for Thalidomide Education and Prescribing Safety). As a percent of total revenue, selling, general and administrative expenses were approximately 51% and 57% for the nine month periods ended September 30, 2002 and 2001, respectively.

Interest and other income and expense: interest and other income for the first nine months of 2002 increased 10.6% to approximately $17.8 million from $16.1 in the same period in 2001. The increase was primarily due to an increase in realized gains of $3.3 million on the sale of corporate bonds offset by lower interest income due to lower interest rates in 2002.

Interest expense for the first nine months of 2002 decreased to approximately $26,300 from approximately $73,400 in the same period in 2001. The decrease was due primarily to the expiration of a three year capital equipment lease in July 2001.

Net loss: The net loss for the nine month period ended September 30, 2002 decreased to $3.6 million from $8.6 million in the same period of 2001. The decreased loss was due to increased revenue of $26.1 million and higher interest and other income of approximately $1.7 million offset by the increase in costs and expenses of approximately $22.7 million.

Liquidity and capital resources: Since inception, we have financed our working capital requirements primarily through product sales, private and public sales of our debt and equity securities, income earned on the investment of proceeds from the sale of such securities and revenue from research contracts and license and milestone payments. Since our initial product launch in the third quarter of 1998, we have recorded net product sales totaling approximately $263.0 million through September 30, 2002. We also received $38.5 million from two separate research and license agreements from 2000 through 2002.

Our net working capital at September 30, 2002 decreased approximately 5% to $291.9 million from $306.5 million at December 31, 2001. The decrease in

17

working capital was primarily due to lower total cash, cash equivalents and marketable securities and deferred revenue offset by higher inventories and other current assets, principally prepaid insurance and other prepaids.

Cash and cash equivalents increased to $100.7 million in the first nine months of 2002 from $47.1 million at December 31, 2001 while investments in marketable debt securities decreased to $188.3 million from $262.9 million in the same period. Total cash, cash equivalents and marketable securities decreased by approximately $21.1 million reflecting the increase in research and development and selling, general and administrative spending during the first nine months of 2002 as well as a decrease in the unrealized gain on our marketable securities portfolio of $2.3 million reflecting current market conditions.

We expect that our rate of spending will increase as the result of research and product development spending, increased clinical trial costs, increased expenses associated with the regulatory approval process and commercialization of products currently in development, increased costs related to the commercialization of THALOMID(R) and increased capital investments. Our current funds, combined with the increasing revenue from sales of THALOMID(R), revenue from the Ritalin(R) products associated with the Novartis collaboration and various research agreements and collaborations are expected to provide sufficient capital for our operations for the foreseeable future.

Contractual Obligations

Our major outstanding contractual obligations relate to our operating (facilities) leases. Our facilities lease expense in future years will increase over previous years as a result of a new lease arrangement entered into in December 2001.

We lease a 44,500-square foot laboratory and office facility in Warren, New Jersey, under a lease with an unaffiliated party, which has a term ending in May 2007 with two five-year renewal options, and an adjoining 29,000-square foot facility which has a term ending in July 2010 with two five-year renewal options. Monthly rental expenses at this site are approximately $64,000. We also lease an 18,000-square foot laboratory and office facility in North Brunswick, New Jersey, under a lease with an unaffiliated party that has a term ending in December 2009 with two five-year renewal options. Monthly rental expenses for this facility are approximately $46,000. We believe that our laboratory

18

facilities are adequate for our research and development activities for at least the next 12 months. During the third quarter 2002, we entered into a lease for an additional 11,400 square feet in a nearby facility. Monthly rental expense is approximately $17,000.

We also lease offices and research facilities in San Diego, California under three operating lease agreements for our West Coast research operations. The minimum annual rents are subject to specified annual rental increases. We also reimburse the lessor for taxes, insurance and operating costs associated with the leases. Monthly rental expense for these facilities is approximately $81,000. Under the terms of the lease, we have an outstanding letter of credit for $150,000 in favor of the lessor, which is fully collateralized by cash. In December 2001, we entered into a new ten-year lease for a 78,200 square foot facility to consolidate our West Coast research operations into one building. We commenced occupation of that facility in the fourth quarter 2002. Monthly rental expense of approximately $172,000 for the new facility began in mid September 2002. We intend to sublease the current facilities until the leases expire in December 2003.

We have entered into agreements with various contractors to improve the new facility we are leasing in San Diego, California. Under such agreements, we have contracted to spend approximately $6.7 million for tenant improvements in the new research facility. We expect to expend funds in the approximate amount of $1.5 million for the remainder of this project over the next three months. This project is being funded through our current capital resources.

Critical Accounting Policies

In December 2001, the SEC requested that all registrants discuss their most "critical accounting policies" in Management's Discussion and Analysis of Financial Condition and Results of Operations. The SEC indicated that a "critical accounting policy" is one which is both important to the portrayal of the company's financial condition and results and requires management's most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. While our significant accounting policies are more fully described in Note 2 to our

19

consolidated financial statements included in our annual report on form 10K, we believe the following accounting policy to be critical:

Revenue Recognition. We have formed collaborative research and development agreements and alliances with several pharmaceutical companies. These agreements are in the form of research and development and license agreements. The agreements are for both early and late stage compounds and are focused on specific disease areas. For the early stage compounds, the agreements are relatively short term agreements that are renewable depending on the success of the compounds as they move through preclinical development. The agreements call for nonrefundable upfront payments, milestone payments on achieving significant milestone events, and in some cases on going research funding. The agreements also contemplate royalty payments on sales if and when the compound receives FDA marketing approval.

In accordance with Staff Accounting Bulletin No. 101 ("SAB 101") Revenue Recognition in Financial Statements, upfront payments are recorded as deferred revenue and recognized over the estimated service period. If the estimated service period is subsequently modified, the period over which the upfront fee is recognized is modified accordingly on a prospective basis. Revenue from the achievement of research and development milestones, which represent the achievement of a significant step in the research and development process, are recognized when and if the specific milestones are achieved. Continuation of certain contracts is dependent upon our achieving specific contractual milestones; however, none of the payments received to date are refundable regardless of the outcome of the project. Research funding is recorded in the period during which the expenses covered by the funding occurred.

Certification of Financial Statements

The certifications by the Company's Chief Executive Officer and Chief Financial Officer of this report on Form 10-Q as required by section 906 of the Sarbanes-Oxley Act of 2002 (18 U.S.C. Section 1350), have been submitted to the Securities and Exchange Commission as additional correspondence accompanying this report.

Cautionary Statements for Forward-Looking Information

The Management's Discussion and Analysis of Financial Condition and Results of Operations provided above contains certain forward-looking statements

20

which involve known and unknown risks, delays, uncertainties and other factors not under our control which may cause actual results, performance and achievements of Celgene to be materially different from the results, performance or other expectations implied by these forward-looking statements. These factors include the results of current or pending clinical trials, actions by the FDA and other factors detailed herein and in our other filings with the Securities and Exchange Commission.

Item 3 - Quantitative and Qualitative Disclosures About Market Risk

Our holdings of financial instruments are comprised of commercial paper and U.S. government and corporate securities. These financial instruments may be classified as securities available for sale and carried at fair value or held to maturity and carried at amortized cost depending upon our intent. Securities classified as available for sale are held for an indefinite period of time and are intended to be used to meet the ongoing liquidity needs of the Company. Unrealized gains and losses (which are deemed to be temporary) on available for sale securities, if any, are reported as a separate component of stockholders' equity. The cost of all debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. The amortization, along with realized gains and losses, is included in interest income and other income. We do not use financial derivatives for investment or trading purposes. As of September 30, 2002, all securities have been classified as available for sale.

We have established guidelines relative to diversification and maturities to maintain safety and liquidity. These guidelines are reviewed periodically and may be modified depending on market conditions. Although our investments are subject to credit risk, our Investment Policy specifies credit quality standards for our investments and limits the amount of credit exposure from any single issue, issuer or type of investment. Our investments are also subject to interest rate risk and will decrease in value if market interest rates increase. Due to the limited number of foreign currency transactions, our foreign exchange currency risk is minimal.
