1.    Basis of Presentation

      The unaudited condensed financial statements have been prepared from the
      books and records of Celgene Corporation (the "Company") in accordance
      with generally accepted accounting principles 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 by generally
      accepted accounting principles for complete 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.

      The interim condensed financial statements should be read in conjunction
      with the financial statements and notes thereto included in the Company's

      share of common stock equal, generally, to the lesser of (i) $18.81 or
      (ii) 90% of the average closing price per share of the common stock for
      the seven trading days immediately prior to the date of conversion.

      As of February 23, 1998, all 503 shares of the Series A Preferred Stock,
      with their respective accretion, had been converted or redeemed into
      3,342, 202 shares of common stock. Through February 23, 1998 the Company

      Management, Inc. ("Chancellor") entered into on June 9, 1997, the Company
      is obligated to issue warrants to Chancellor to acquire a number of shares
      of Common Stock equal to (i) 1,500,000 divided by the Conversion Price
      ($6.50 at June 30, 1998) in effect on the issuance date (230,769 warrants
      as of June 30, 1998) plus (ii) 37.5% of the conversion shares issuable on
      such issuance date upon conversion of all shares of Series B Preferred
      Stock issued through the issuance date (288,461 warrants as of June 30,
      1998). All such warrants will have a term of four years from the issuance
      date and an exercise price equal to 115% of the Conversion Price in effect
      on the issuance date.

5.    Discontinued Operations

      On January 9, 1998, the Company sold its chiral intermediates business to
      Cambrex Corporation for approximately $15.0 million. The terms of the
      agreement provided for the sale of chiral assets of approximately $485,000
      for proceeds of $7.5 million on the contract date plus future royalties
      with a present value not exceeding $7.5 million, with certain minimum
      royalty payments in the third through sixth year following the closing of
      the transaction. Included in the transaction are the rights to the
      Company's enzymatic technology for the production of chirally pure
      intermediates for the pharmaceutical industry, including the current
      pipeline of third party products and the equipment and personnel
      associated with the business.


6.    New Accounting Pronouncement

      Effective January 1, 1998, the Company adopted Statement of Financial
      Standards (SFAS) No. 130, "Reporting Comprehensive Income". This statement
      establishes standards for reporting and display of comprehensive income,
      which consists of all changes in equity from non-shareholder sources.
      Prior year financial statements conform to the requirements of SFAS 
      No. 130

      Comprehensive income includes net income and other comprehensive income
      which refers to those revenues, expenses, gains and losses which are
      excluded from net income. Other comprehensive income includes unrealized
      gains and losses on marketable securities classified as
      available-for-sale, which prior to adoption were reported separately in
      shareholders' equity.

      In June 1998, SFAS No. 133, "Accounting for Derivative Instruments and
      Hedging Activities", was issued and is effective for financial statements
      beginning January 1, 2000. SFAS No. 133 requires derivative instruments to
      be recognized as Assets and Liabilities and be recorded at Fair Value. The
      Company is currently not party to any Derivative Instruments. Any future
      transactions involving Derivative Instruments will be evaluated based on
      SFAS No.133.


7.    Subsequent Events

      On July 16, 1998 the Company received final approval from the U.S. food
      and Drug Administration (FDA) to market and sell Thalomid (thalidomide)
      for the treatment of erythema nodosum leprosum (ENL), a severe and
      debilitating condition associated with leprosy. Thalomid is the Company's
      first product approved for commercialization.

      On July 2, 1998, the Company closed on a license and distribution
      agreement with Biovail Corporation International granting Biovail
      exclusive Canadian marketing rights for d-methylphenidate hydrochloride
      (d-MPH) which is being developed by Celgene. The drug is a chirally pure
      version of dl-MPH, also known as Ritalin(R). Under the terms of the
      agreement, Biovail purchased $2.5 million of Celgene stock for $12.52 per
      share, a 25% premium to the market price on that date. Celgene will also
      receive licensing fees and royalties.

Part 1 - Financial Information
Item 2 - Management's Discussion and Analysis of Financial Condition and Results
of Operations.


Results of Operations
- ---------------------

Six month period ended June 30, 1998 vs.
Six month period ended June 30,1997
- -----------------------------------

      Total Revenues. The Company's total revenues for the six months ended June
30, 1998 decreased significantly to approximately $80,000 from approximately
$523,000 in the same period of 1997. Revenue for the period in both years was
entirely from research contracts. The decrease in revenue in 1998 was primarily
due to the completion of a research contract with BASF in December 1997.

      Research and development expenses. Research and development expenses
increased slightly, to $8.7 million in 1998 from $8.5 million in the same period
in 1997. The increase was due to increased spending for university research
programs (approximately $636,000), primarily with The University of Glasgow and
Rockefeller University, offset by a decrease in Preclinical Toxicology
(approximately $436,000), as research projects involving Thalomid, SelCIDs, and
d-methylphenidate advanced from preclinical to clinical trial status.

      Selling, general and administrative expenses. Selling, general and
administrative expenses for the six months ended June 30, 1998 increased by 118%
to approximately $7.3 million from $3.4 million in the same period of 1997. The
increase is attributable to $3.0 million of expenses for the formation of a
sales and marketing organization and related activities and $0.5 million of
expenses to establish a Medical Affairs and Drug Safety department, both in
anticipation of the commercial launch of Thalomid which was approved by the FDA
on July 16, 1998.

      Interest income and expense. Interest income for the first six months of
1998 increased 5% to approximately $361,000 from $343,000 in the same period of
1997. The increase was due to higher average cash balances in 1998. Interest
expense decreased to approximately $6,000 from $94,000 in 1997. The decrease was
due to the conversion to equity of all of the 8% convertible debentures by mid
1997.

      Net loss from continuing operations. The net loss from continuing
operations for the period ended June 30, 1998 increased by 40% to $15.6 million
from $11.1 million in the same period of 

                                       11


1997. The increase was due primarily to the increased spending on the sales and
marketing organization and the Medical Affairs department as described above.

      Discontinued operations. The net loss from discontinued operations
decreased significantly in the first six months of 1998 to approximately $60,000
from $340,000 in the same period of 1997. The decrease was due to the sale of
the Chiral Intermediates business on January 9, 1998. The $60,000 loss in 1998
represents expenses for the nine day period preceding the sale. The loss in 1997
represents revenues of approximately $872,000 offset by expenses of $1,212,000
for the discontinued operations.


Three month period ended June 30, 1998 vs.
Three month period ended June 30, 1997
- --------------------------------------

      Total Revenues. The company received no revenues during the second quarter
1998. Revenues during the same period in 1997 totaled approximately $273,000.
The revenues were primarily from a research contract with BASF which was
completed in December 1997.

      Research and development expenses. Research and development expenses for
the second quarter 1998 were up slightly to approximately $4.8 million from $4.5
million an increase of approximately 6%. The increase in spending was due to an
increase in consulting fees incurred in connection with Regulatory matters
(approximately $229,000), and an increase in university research programs
(approximately $314,000), primarily with the University of Glasgow, offset in
part by a decrease in preclinical toxicology (approximately $338,000), as
research projects involving Thalomid, SelCIDs, and d-methylphenidate advanced
from preclinical to clinical trial status. All other research and development
expenses increased by approximately $100,000.

      Selling, general and administrative expenses. Selling, general and
administrative expenses increased by 97% to approximately $4.1 million in the
second quarter 1998 versus $2.1 million during the same period in 1997. The
increase was primarily in sales and marketing ($1.5 million), as a full sales
staff was added and marketing activities were increased, and the Medical Affairs
and Drug Safety Department was expanded ($300,000), both in preparation for the
approval and commercial launch of Thalomid. All other selling, general and
administrative expenses increased approximately $200,000.

      Interest income and expense. Interest income decreased slightly in the
second quarter 1998 versus the same period in 

                                       12


1997, to approximately $111,000 from $135,000, due to lower average cash
balances. Interest expense decreased to approximately $5,000 from $26,000 due to
the conversion to equity of all of the 8% convertible debentures by mid 1997.

      Net loss from continuing operations. The net loss from continuing
operations for the second quarter 1998 increased 41% over the same period in
1997 to approximately $8.8 million from $6.2 million. The increased loss was due
primarily to the increase in sales and marketing and Medical Affairs as
described above.

      Discontinued Operations. There was no discontinued operation activity in
the second quarter of 1998 as the chiral intermediate business was sold on
January 9, 1998. Discontinued operations in the second quarter 1997 of
approximately $257,000 consisted of revenues of $367,000 offset by expenses of
$624,000.

      Liquidity and Capital Resources. Since inception, the Company has financed
its working capital requirements primarily through private and public sales of
its debt and equity securities, income earned on the investment of the proceeds
from the sale of such securities, and revenues from research contracts and
product sales from certain businesses which the company has since sold. The
Company has raised approximately $99.0 million in net proceeds from three public
and three private offerings, including its initial public offering in July 1987.

      The Company's net working capital at June 30, 1998 was $6.2 million versus
$13.4 at December 31, 1997. The decrease was attributable to a decrease in cash
and marketable securities of $3.5 million, a decrease in accounts receivable of
$1.4 million and an increase in accounts payable of $1.7 million. Assets held
for disposal of $485,000 at December 31, 1997 represented the net assets of the
chiral intermediate business pending sale. Net working capital consisted
principally of cash, cash equivalents, and marketable securities, accounts
receivable and accounts payable.

      The Company expects that its rate of spending will increase as the result
of increased clinical trial costs and expenses associated with the regulatory
approval process and commercialization of products now in development. In order
to assure funding for the Company's future operations, the Company will seek
additional capital resources. The Company is currently considering partnering
options and other financing sources. However, no assurances can be given that
the Company will be successful in raising additional capital on terms acceptable
to it. In June Celgene signed a license and distribution agreement 

                                       13


with Biovail Laboratories granting exclusive distribution rights in Canada to
Biovail for d-methylphenidate. In early July, Biovail purchased $2.5 million of
Celgene's stock at a 25% premium to the market price. The agreement calls for
certain milestone payments, the first of which is expected to be received in the
fourth quarter of this year pending commencement of a pivotal clinical trial. On
July 16, 1998, Celgene received approval from the FDA to market Thalomid
(thalidomide). Revenues from the sale of Thalomid are anticipated in the fourth
quarter.


      Year 2000 Computer Systems Compliance - Many older computer software
programs refer to years in terms of their final two digits only. Such programs
may interpret the year 2000 to mean the year 1900 instead. If not corrected,
those programs could cause date-related transaction failures.

      During the first six months of 1998, the Company has replaced all personal
computers, with the exception of several computers connected to laboratory
analytic equipment, with Year 2000 compliant machines. All office applications
and the Adverse Event Reporting software are year 2000 Compliant. During the
quarter ended June 30, 1998, the Company purchased and installed a new Year 2000
compliant financial system software package, including general ledger and
accounts payable. Effective July 1, 1998, the Company has gone live with the new
system. The Company is confident that by year end 1998, all critical systems and
software will have been addressed. As to the date critical nature of the
laboratory computers, an assessment will be complete with a plan to replace
those machines if necessary by early 1999. Additional costs to correct Year 2000
problems are not expected to be material. Based on current plans and efforts to
date, the Company expects that there will be no material adverse effect on
operations. There is no guarantee, however, that all problems will be foreseen
and corrected, that Year 2000 problems at the Company's suppliers, customers,
and at governmental agencies will not adversely affect the Company, or that no
material disruption of the Company's business will occur as a result of Year
2000 problems.
