              Notes to Unaudited Consolidated Financial Statements
                                  June 30, 2004

1.  ORGANIZATION AND BASIS OF PRESENTATION

Celgene Corporation and subsidiaries ("Celgene" or the "Company") is an
integrated biopharmaceutical company primarily engaged in the discovery,
development and commercialization of innovative therapies designed to treat
cancer and immunological diseases through regulation of cellular, genomic and
proteomic targets.

The unaudited consolidated financial statements included herein have been
prepared from the books and records of the Company pursuant to the rules and
regulations of the Securities and Exchange Commission for reporting on Form
10-Q. Certain information and footnote disclosures normally included in complete
consolidated financial statements prepared in accordance with accounting
principles generally accepted in the United States of America have been
condensed or omitted pursuant to such rules and regulations. Certain
reclassifications have been made to the prior period's financial statements in
order to conform to the current period's 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.

Interim results may not be indicative of the results that may be expected for
the year. In the opinion of management, all adjustments considered necessary for
a fair presentation of these interim statements have been included and are of a
normal and recurring nature.

2.  EARNINGS PER SHARE

Basic earnings per common share is computed by dividing net income available to
common stockholders by the weighted-average number of common shares outstanding
during the period. Diluted earnings per common share is computed by dividing net
income available to common stockholders by the weighted-average number of common
shares outstanding during the period increased to include all additional common
shares that would have been outstanding assuming potentially dilutive common
shares had been issued and any proceeds thereof used to repurchase common stock
at the average market price during the period. The proceeds used to repurchase
common stock are assumed to be the sum of the amount to be paid to the Company
upon exercise of options, the amount of compensation cost attributed to future
services and not yet recognized and, if applicable, the amount of income taxes
that would be credited to or deducted from capital upon exercise. The potential
common shares related to the June 2003 convertible notes issuance were
anti-dilutive and were excluded from the diluted earnings per share computation
for the three and six month periods ended June 30 2004 and 2003.

The total number of potential common shares excluded from the diluted earnings
per share computation because their inclusion would have had an anti-dilutive
was 9,302,777 and 10,750,809 for the three month period ended June 30, 2004 and
2003, respectively, and 9,879,395 and 11,709,585 for the six month period ended
June 30, 2004 and 2003, respectively.

6.  STOCK BASED COMPENSATION

The Company applies the intrinsic value-based method of accounting prescribed by
Accounting Principles Board ("APB") Opinion No. 25, "ACCOUNTING FOR STOCK ISSUED
TO EMPLOYEES," and related interpretations, in accounting for its fixed stock
option plans. As such, compensation expense for grants to employees or members
of the Board of Directors would be recorded on the date of grant only if the
current market price of the Company's stock exceeded the exercise price.
Statement of Financial Accounting Standards ("SFAS") No. 123, "ACCOUNTING FOR
STOCK-BASED COMPENSATION" ("SFAS 123") as amended, establishes accounting and
disclosure requirements using a fair value-based method of accounting for
stock-based employee compensation plans. As permitted under SFAS 123, the
Company has elected to continue to apply the intrinsic value-based method of
accounting described above, and has adopted the disclosure requirements of SFAS
123, as amended.

If the exercise price of employee or director stock options is less than the
fair value of the underlying stock on the grant date, the Company records
deferred compensation for the difference and amortizes such amounts to expense
over the vesting period of the options. Options or stock awards issued to
non-employees and consultants are recorded at fair value as determined in
accordance with SFAS 123 and Emerging Issues Task Force

Restricted Stock Awards: During 2001, the Company issued to certain employees an
aggregate of 52,500 restricted stock awards. Such restricted stock awards will
vest on September 19, 2006, unless certain conditions that would trigger
accelerated vesting are otherwise met prior to such date. The fair value of
these restricted stock awards at the grant date was $1.4 million and is being
amortized as compensation expense over the contractual vesting period.
Compensation expense relating to these restricted stock awards was approximately
$0.1 million for the three and six month periods ended June 30, 2004 and 2003,
respectively, and was classified as selling, general and administrative
expenses.

Non-Employee Share Based Payments: Expense relating to stock, stock
options and warrants issued to consultants, advisors or financial institutions
was approximately $0.1 million for each of the three month periods ended June
30, 2004 and 2003 and approximately $0.1 million and $0.2 million for the six
month periods ended June 30, 2004 and 2003, respectively.

Amortization of acquisition intangibles was approximately $0.1 million for the
three month period ended June 30, 2004 and 2003, respectively, and approximately
$0.2 million for the six month period ended June 30, 2004 and 2003,
respectively. Assuming no changes in the gross carrying amount of intangible
assets, the amortization of intangible assets for the next five fiscal years is
estimated to be approximately $0.3 million for the years 2004 through 2007 and
$0.2 million for 2008.

Goodwill was $3.5 million at June 30, 2004 and December 31, 2003, respectively,
and has been allocated to the Company's Stem Cell Therapies segment. In
accordance with SFAS No. 142, "GOODWILL AND OTHER INTANGIBLE ASSETS," goodwill
is not amortized, but rather is reviewed at least annually for impairment.

8.  COMPREHENSIVE INCOME

The components of comprehensive income, which represents the change in equity
from non-owner sources, for the three and six month periods ended June 30, 2004

10.  ALKERAN DISTRIBUTION AGREEMENT

On March 31, 2003, the Company entered into a three-year supply and distribution
agreement with GlaxoSmithKline ("GSK") to distribute, promote and sell
ALKERAN(R) (melphalan), a therapy approved by the U.S. Food and Drug
Administration for the palliative treatment of multiple myeloma and carcinoma of
the ovary. Under the terms of the agreement, Celgene purchases ALKERAN tablets
and ALKERAN for infusion from GSK and distributes the products in the United
States under the Celgene label. The agreement requires the Company to purchase
certain minimum quantities each year for the initial three-year term under a
take-or-pay arrangement aggregating $56.6 million over such period and is
automatically extended by successive one-year periods, unless at least one-year
prior to the renewal date, either party advises the other party that it elects
not to extend the agreement. The remaining minimum purchase requirements at June
30, 2004 were $43.5 million.

11.  PHARMION AGREEMENTS

In March 2004, the Company converted its $12.0 million Pharmion Senior
Convertible Promissory Note, with a principal amount of $12.0 million, and
accrued interest of approximately $0.7 million into 1,150,511 shares of Pharmion
common stock at a conversion price of $11.00 per share. The Pharmion equity
securities investment, which had a fair value at June 30, 2004 of $56.3 million,
is classified as Marketable Securities Available for Sale and carried at fair
value. The unrealized gain of $43.6 million is included in Accumulated Other
Comprehensive Income in the Stockholders' Equity section of the Consolidated
Balance Sheet. For more information on the Pharmion Senior Convertible
Promissory Note and other Pharmion agreements, refer to Note 15 of the Notes to
the Consolidated Financial Statements included in the Company's 2003 Annual
Report on Form 10-K.

PART I - FINANCIAL INFORMATION

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

FACTORS AFFECTING FUTURE RESULTS

Future operating results will depend on many factors, including demand for our
products, regulatory approvals of our products, the timing and market acceptance
of new products launched by us or competing companies, the timing of research
and development milestones, challenges to our intellectual property, and our
ability to control costs. The most salient factors are, in the near term,
competition with THALOMID(R), including generic competition, and delays in the
introduction of REVLIMID(TM) and, in the longer term, failure to commercialize
our early-stage drug candidates.

NEAR-TERM COMPETITION WITH THALOMID: In June 2003, the U.S. Food and Drug
Administration ("FDA") approved Millennium Pharmaceuticals' Velcade(R) for use
in refractory multiple myeloma patients. While it is possible that Velcade could
reduce THALOMID sales in multiple myeloma, we believe that THALOMID will
continue to be used as a first-line treatment and that Velcade will usually be
used in patients that have not had success with THALOMID. Also, generic
competition could reduce THALOMID sales. However, we own intellectual property,
which includes, for example, numerous United States patents covering our "System
for Thalidomide Education and Prescribing Safety," (or S.T.E.P.S.(R))
distribution program, which all patients receiving thalidomide must follow and
which are listed in the FDA Approved Drug Products with Therapeutic Equivalence
Evaluation (orange book). These patents do not expire until the years 2018-2020.
We also have exclusive rights to several issued patents covering the use of
THALOMID in oncology. Even if generic competition could manage to enter the
market, it is unlikely such products could do so before 2007 given the time
needed to commercialize a product; by that time, we expect to have at least
partially replaced THALOMID with REVLIMID. In February 2004, the FDA accepted
for review our Supplemental New Drug Application (sNDA) seeking approval to
market THALOMID for the treatment of multiple myeloma. We expect the FDA's
action in the fourth quarter of this year, which if unfavorable could have a
negative impact on the Company's financial position and/or results of
operations.

DELAY IN THE INTRODUCTION OF REVLIMID: While we have made progress in REVLIMID's
path to regulatory approval and ongoing trials remain on or ahead of their
planned patient accrual timelines for potential approvals in 2005, a delay in
the introduction of REVLIMID or its failure to demonstrate efficacy or an
acceptable safety profile could adversely affect our business, financial
condition and results of operations. On April 28, 2004, we announced plans to
stop Phase III trials in metastatic melanoma due to lack of efficacy.

                                       16


FAILURE TO COMMERCIALIZE EARLY-STAGE DRUG CANDIDATES: Our long-term success and
sustainability depends on our ability to move our earlier-stage drug candidates
through development and to realize the commercial potential of our broad
pipeline.

RESULTS OF OPERATIONS

THREE-MONTH PERIOD ENDED JUNE 30, 2003

TOTAL REVENUE: Total revenue and related percentages for the three-month periods
ended June 30, 2004 and 2003 were as follows:

--------------------------------------------------------------------------------

THALOMID(R) net sales were higher in the three-month period ended June 30, 2004
primarily due to price increases implemented in the second half of 2003 and in
the second quarter of 2004. The total number of prescriptions, which increased
11.0% from the prior year period, was offset by lower average daily doses. The
three-month period ended June 30, 2003 included the benefit of the market
introduction of two new higher strength formulations during March 2003 that
resulted in increased orders at pharmacies and thus an increase in second
quarter 2003 sales volumes. Focalin(TM) net sales were lower in the three-month
period ended June 30, 2004 due to the timing of shipments to Novartis for their
commercial distribution. ALKERAN(R) net sales in the three-month period ended
June 30, 2004 were lower due to manufacturing and supply delays from the
third-party supplier.

Collaborative agreements and other revenue for the three-month period ended June
30, 2004 included approximately $1.9 million of research funding and S.T.E.P.S.
license fees received in connection with the Pharmion agreements, $0.9 million
of umbilical cord blood enrollment, collection and storage fees generated
through our Stem Cell Therapies segment and $0.1 million of other revenue. The
three-month period ended June 30, 2003 included approximately $1.3 million of
research funding and S.T.E.P.S. license fees received from Pharmion, $0.9

                                       17


million of umbilical cord blood enrollment, collection and storage fees and $0.1
million of other revenue. We anticipate receiving a milestone payment in the
third quarter of 2004 based on the potential submission of a New Drug
Application ("NDA") by Novartis relating to Focalin LA(TM).

Royalty revenue reflects royalties received from Novartis on sales of their
entire family of Ritalin(R) drugs. The increase in royalty revenue was due to
higher Ritalin LA(R) sales in the three-month period ended June 30, 2004, and an
increase in the royalty rate.

COST OF GOODS SOLD: Cost of goods sold and related percentages for the
three-month periods ended June 30, 2004 and 2003 were as follows:

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
Cost of goods sold                                $   14,094         $   13,874
Increase from prior year                          $      220                N/A
Percentage increase from prior year                     1.6%                N/A
Percentage of net product sales                        17.8%              22.2%
--------------------------------------------------------------------------------

Cost of goods sold increased from the prior year period primarily as a result of
higher royalties on THALOMID net sales, and, to a much lesser extent, higher
costs at our Stem Cell Therapies segment, which resulted from expensing
pre-approval inventory costs associated with processing umbilical cord blood and
tissue units. These increases were largely offset by lower ALKERAN costs.

Cost of goods sold as a percentage of net product sales decreased primarily due
to higher gross profit margins on THALOMID net sales that resulted from price
increases initiated in the second half of 2003 and in the second quarter of 2004
and lower ALKERAN costs as a percentage of net sales.

RESEARCH AND DEVELOPMENT: Research and development expenses consist primarily of
salaries and benefits, contractor fees, principally with contract research

--------------------------------------------------------------------------------

Research and development expenses increased from the prior year period primarily
due to increased clinical spending on REVLIMID(TM) Phase III SPA trials for
multiple myeloma and REVLIMID Phase II trials for myelodysplastic syndromes and
multiple myeloma. During the three-month period ended June 30, 2004,
approximately $19.4 million was spent on human pharmaceutical clinical programs;
$9.1 million was spent on other human pharmaceutical programs, including
toxicology, analytical research and development, drug discovery, quality and
regulatory affairs; $8.3 million was spent on biopharmaceutical discovery and
development programs; and $1.8 million was spent on stem cell, biomaterials and
placental extraction programs. These expenditures support multiple core
programs, including THALOMID, REVLIMID, ACTIMID(TM), CC-11006, CC-10004,
PDE4/TNF-(alpha) inhibitors and other investigational compounds, such as kinase
inhibitors, benzopyrans, ligase inhibitors, tubulin inhibitors and placental
derived stem cell programs. During the three-month period ended June 30, 2003,
approximately $13.1 million was spent on human pharmaceutical clinical programs;
$7.5 million was spent on other human pharmaceutical programs, including
toxicology, analytical research and development and drug discovery; $9.1 million
was spent on biopharmaceutical discovery and development and agro-chemical
programs; and $0.8 million was spent on stem cell, biomaterials and placental
extraction programs. As total revenue increases, research and development
expense may continue to decrease as a percentage of total revenue, however the
actual dollar amount will continue to increase as earlier stage compounds are
moved through the preclinical and clinical stages. Generally, the time to
completion of each phase is estimated as follows:

                           PHASE I -----  1-2 YEARS
                           PHASE II ----  2-3 YEARS
                           PHASE III ---  2-3 YEARS

Due to the significant risk factors 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

                                       19


clinical development, which would significantly impact the costs incurred to
bring a project to completion.

SELLING, GENERAL AND ADMINISTRATIVE: Selling expenses consist primarily of
salaries and benefits for sales and marketing and customer service personnel and
other commercial expenses to support the sales force. General and administrative
expenses consist primarily of salaries and benefits, outside professional
services for legal, audit, tax and investor activities, medical affairs expenses
and allocations of facilities costs, principally for rent, utilities and
property taxes.

Selling, general and administrative expenses and related percentages for the
three-month periods ended June 30, 2004 and 2003 were as follows:

--------------------------------------------------------------------------------

Selling, general and administrative expenses increased from the prior year
period as a result of an increase of approximately $1.1 million in general
administrative and medical affairs expenses primarily due to higher headcount
related expenses and an increase of approximately $1.9 million in sales force
expenses primarily due to the creation of a sales operations group, which among
other things manages pricing and reimbursement, corporate accounts, customer
service and government affairs as well as, sales fleet expenses, offset by a
decrease in product marketing expenses.

INTEREST AND OTHER INCOME: Interest and other income increased 50.0% to
approximately $6.7 million for the three-month period ended June 30, 2004,
compared to approximately $4.5 million in the prior year period. The increase
was primarily due to an increase in interest income as a result of higher
average balances of cash, cash equivalents and marketable securities available
for sale following the issuance of our $400 million convertible notes issued on
June 3, 2003 as well as generated through operations, partially offset by lower
realized gains on the sale of marketable securities.

INTEREST EXPENSE: Interest expense increased to approximately $2.4 million for
the three-month period ended June 30, 2004 compared to approximately $0.6
million for the prior year period. The increase reflects interest expense and
amortization of debt issuance costs on the $400 million convertible notes issued
on June 3, 2003, whereas the prior year period only reflects one month of
interest expense.

                                       20


INCOME TAX PROVISION: For the three-month period ended June 30, 2004, the income
tax provision was approximately $1.2 million and reflects an underlying
effective tax rate of 8.5%. For the prior year period, the income tax provision
was approximately $0.2 million and reflects an underlying effective tax rate of
6.8%.

--------------------------------------------------------------------------------

Net income increased approximately $9.6 million in the three-month period ended
June 30, 2004 compared to the prior year period primarily due to an increase in
total revenues of approximately $20.5 million (attributable primarily to an
increase in THALOMID net sales of $19.7 million) offset by higher operating
expenses of approximately $10.4 million.

THALOMID(R) net sales were higher in the six-month period ended June 30, 2004
primarily due to price increases implemented in the second half of 2003 and the
second quarter of 2004. The total number of prescriptions, which increased 10.5%
from the prior year period, was offset by lower average daily doses. The
six-month period ended June 30, 2003 included the benefit of the market
introduction of two new higher strength formulations during March 2003 that
resulted in increased orders at pharmacies and thus an increase in second
quarter 2003 sales volumes. Focalin(TM) net sales were higher in the six-month
period ended June 30, 2004 due to the timing of shipments to Novartis for their
commercial distribution. ALKERAN(R) net sales were higher in the six-month
period ended June 30, 2004 primarily due to the fact that the ALKERAN supply and
distribution agreement with GlaxoSmithKline was executed in March 2003 and,
consequently, ALKERAN sales did not commence until the second quarter of 2003.
ALKERAN net sales in the six-month period ended June 30, 2004 were unfavorably
impacted by manufacturing and supply delays from the third-party supplier.

Collaborative agreements and other revenue for the six-month period ended June
30, 2004 included approximately $3.2 million of research funding and S.T.E.P.S.
license fees received in connection with the Pharmion agreements, $1.7 million
of umbilical cord blood enrollment, collection and storage fees generated
through our Stem Cell Therapies segment and $0.1 million of other revenue. The
six-month period ended June 30, 2003 included approximately $1.6 million of
research funding and license fees received from Pharmion, $1.6 million of
umbilical cord blood enrollment, collection and storage fees and $0.2 million of
other revenue. We anticipate receiving a milestone payment in the third quarter
of 2004 based on the potential submission of an NDA by Novartis relating to
Focalin LA(TM).

Royalty revenue reflects royalties received from novartis on sales of their
entire family of Ritalin(R) drugs. the increase in royalty revenue was due to
higher Ritalin LA(R) sales in the six-month period ended June 30, 2004, and an
increase in the royalty rate.

COST OF GOODS SOLD: Cost of goods sold and related percentages for the six-month

--------------------------------------------------------------------------------

Cost of goods sold increased from the prior year period primarily as a result of
higher product sales (i.e., THALOMID, Focalin and ALKERAN), higher royalties on
THALOMID net sales and higher costs at our Stem

                                       22


Cell Therapies segment, which resulted from expensing pre-approval inventory
costs associated with processing umbilical cord blood and tissue units.

Cost of goods sold as a percentage of net product sales decreased slightly due
to higher gross profit margins on THALOMID net sales that resulted from price
increases initiated in the second half of 2003 and in the second quarter of
2004. The increase in THALOMID gross profit margins was largely offset by higher
ALKERAN sales, and, to a much lesser extent, higher Focalin sales (both of which
have a higher cost structures than THALOMID) and by higher costs associated with
the processing of more umbilical cord blood and tissue units at our Stem Cell
Therapies segment.

--------------------------------------------------------------------------------

Research and development expenses increased from the prior year period primarily
due to increased clinical spending on REVLIMID(TM) Phase III SPA trials for
multiple myeloma, REVLIMID Phase II trials for myelodysplastic syndromes and
multiple myeloma and THALOMID Phase III trials for multiple myeloma. During the
six-month period ended June 30, 2004, approximately $40.1 million was spent on
human pharmaceutical clinical programs; $16.2 million was spent on other human
pharmaceutical programs, including toxicology, analytical research and
development, drug discovery, quality and regulatory affairs; $16.7 million was
spent on biopharmaceutical discovery and development programs; and $3.4 million
was spent on stem cell, biomaterials and placental extraction programs. These
expenditures support multiple core programs, including THALOMID, REVLIMID,
ACTIMID(TM), CC-11006, CC-10004, PDE4/TNF-(alpha) inhibitors and other
investigational compounds, such as kinase inhibitors, benzopyrans, ligase
inhibitors, tubulin inhibitors and placental derived stem cell programs. During
the six-month period ended June 30, 2003, approximately $22.9 million was spent
on human pharmaceutical clinical programs; $11.9 million was spent on other
human pharmaceutical programs, including toxicology, analytical research and
development and drug discovery; $18.7 million was spent on biopharmaceutical
discovery and development and agro-chemical programs; and $1.7 million was spent
on stem cell, biomaterials and placental extraction programs. As total revenue
increases, research and development expense may continue to decrease as a
percentage of total revenue,

                                       23


however the actual dollar amount will continue to increase as earlier stage
compounds are moved through the preclinical and clinical stages.

--------------------------------------------------------------------------------

Selling, general and administrative expenses increased from the prior year
period as a result of an increase of approximately $4.4 million in general
administrative and medical affairs expenses primarily due to higher headcount
related expenses and an increase of approximately $3.0 million in sales force
expenses primarily due to the creation of a sales operations group, which among
other things manages pricing and reimbursement, corporate accounts, customer
service and government affairs as well as, sales fleet expenses, offset by a
decrease in product marketing expenses.

INTEREST AND OTHER INCOME: Interest and other income increased 48.5% to
approximately $13.7 million for the six-month period ended June 30, 2004,
compared to approximately $9.2 million in the prior year period. The increase
was primarily due to an increase in interest income as a result of higher
average balances of cash, cash equivalents and marketable securities available
for sale following the issuance of our $400 million convertible notes issued on
June 3, 2003 as well as generated through operations, partially offset by lower
realized gains on the sale of marketable securities.

INTEREST EXPENSE: Interest expense increased to approximately $4.8 million for
the six-month period ended June 30, 2004 compared to approximately $0.6 million
for the prior year period. The increase reflects interest expense and
amortization of debt issuance costs on the $400 million convertible notes issued
on June 3, 2003, whereas the prior year period only reflects one month of
interest expense.

INCOME TAX PROVISION: For the six-month period ended June 30, 2004, the income
tax provision was approximately $2.0 million and reflects an underlying
effective tax rate of 8.5%. For the prior year period, the income tax provision
was approximately $0.3 million and reflects an underlying effective tax rate of
8.2%.

--------------------------------------------------------------------------------

Net income increased approximately $17.2 million in the six-month period ended
June 30, 2004 compared to the prior year period primarily due to an increase in
total revenues of approximately $54.3 million (attributable primarily to an
increase in THALOMID net sales of $43.3 million) offset by higher operating
expenses of approximately $35.7 million.

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities increased to approximately $25.0
million for the six-month period ended June 30, 2004 compared to $5.3 million
for the prior year period. The increase was primarily due to higher earnings and
recent upward trends in net working capital levels (i.e., current assets minus
current liabilities). Net working capital at June 30, 2004 was $736.4 million
and included increases from December 31, 2003 levels in cash, cash equivalents
and marketable securities primarily due to higher net earnings and inclusion of
the Pharmion equity securities, accounts receivable primarily due to higher net
product sales and inventory primarily due to higher ALKERAN inventory levels.
Partially offsetting these increases was an increase in accounts payable.
Accrued expenses decreased from December 31, 2003 levels primarily due to 2003
incentive-based compensation, profit sharing and other accruals that were paid
during the first quarter of 2004.

Net cash used in investing activities was $125.8 million for the six-month
period ended June 30, 2004 compared to net cash provided by investing activities
of $27.6 million for the prior year period. Included in the six-month period
ended June 30, 2004 was a $7.0 million investment in Royalty Pharma Strategic
Partners, LP. The investment is classified under Other Assets on the
Consolidated Balance Sheet and measured at cost. Also included in the 2004
period investing activities were approximately $114.1 million of net marketable
securities purchases and capital spending of $4.7 million.

                                       25


Included in the six-month period ended June 30, 2003 was approximately $32.8
million of net marketable securities sales and capital spending of $5.2 million.

Net cash provided by financing activities was $7.9 million for the six-month
period ended June 30, 2004 compared to $394.6 million in the prior year period.
Included in the prior year period were net proceeds of $387.9 million from the
issuance of our convertible notes on June 3, 2003.

We expect increased research and product development costs, clinical trial
costs, expenses associated with the regulatory approval process and
commercialization of products and capital investments. However, existing cash,
cash equivalents and marketable securities available for sale, combined with
expected net product sales and revenues from various research, collaboration and
royalties agreements are expected to provide sufficient capital resources to
fund our operations for the foreseeable future.

The Company's major outstanding contractual obligations are described in greater
detail in Notes 9 and 17 of the Notes to the Consolidated Financial Statements
included in the Company's 2003 Annual Report on Form 10-K and in the
Management's Discussion and Analysis of Financial Condition and Results of
Operation section of the Company's 2003 Annual Report on Form 10-K.

In 2003, we established a Long-Term Incentive Plan ("LTIP") designed to provide
key officers and executives with performance based incentive opportunities
contingent upon achievement of pre-established

                                       26


corporate performance objectives, and payable only if employed at the end of the
performance cycle. The 2003 performance cycle began on May 1, 2003 and ends on
December 31, 2005 (the "2003 Cycle"). The 2004 performance cycle began on
January 1, 2004 and will end on December 31, 2006 (the "2004 Cycle").
Performance measures for the 2003 Cycle and the 2004 Cycle are based on the
following components: 25% on earnings per share, 25% on net income and 50% on
revenue.

Payouts may be in the range of 0% to 200% of the participant's salary for the
2003 Cycle and 0% to 150% of the participant's salary for the 2004 Cycle. The
maximum potential payout, assuming objectives are achieved at the 200% level and
150% level, respectively, is $6.1 million for the 2003 Cycle and $4.9 million
for the 2004 Cycle. Such awards are payable in cash or, at its discretion, the
Company can elect to pay the same value in its common stock based upon the
Company's common stock fair value at the payout date. Upon a change in control,
participants will be entitled to an immediate payment equal to their target
award, or, if higher, an award based on actual performance through the date of
the change in control.

2004 FINANCIAL OUTLOOK

In our July 22, 2004 earnings release, we updated the earnings estimate, as set
forth below, for full year 2004. Although management believes that the July 22,
2004 earnings projection continues to reflect the current thinking of
management, there can be no assurance that revenues or earnings will develop in
the manner projected or if the analysis, on which the earnings projection was
based, were to be redone on the date hereof that there would be no change in the
guidance.

REVENUES: We updated our 2004 guidance for total revenue to be in the range of
$370 to $390 million, with THALOMID net sales targeted to be in the range of
$295 to $305 million. We maintained our 2004 target revenue for the Ritalin(R)
family of drugs in a range of $40 million, which includes a significant
milestone payment for filing an NDA for Focalin LA(TM).

OPERATING EXPENSES: We maintained our 2004 guidance for research and development
expenses and selling, general and administrative expenses in the range of $160
million to $170 million and $115 million to $125 million, respectively.

EARNINGS PER SHARE: We updated our full year 2004 guidance for diluted earnings
per share to be in the range of $0.50 to $0.60 per share.

CRITICAL ACCOUNTING POLICIES

A critical accounting policy is one which is both important to the portrayal of
the Company's financial condition and results of operation 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. The

                                       27


Company's significant accounting policies are fully described in Note 1 of the
Notes to the Consolidated Financial Statements included in the Company's 2003
Annual Report on Form 10-K. The Company's critical accounting policies are
disclosed in the Management's Discussion and Analysis of Financial Condition and
Results of Operation section of the Company's 2003 Annual Report on Form 10-K.
There have been no significant changes with respect to such accounting policies.

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 which
involve known and unknown risks, delays, uncertainties and other factors not
under the Company's 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 the Company's other filings with the
Securities and Exchange Commission.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following discussion provides forward-looking quantitative and qualitative
information about the Company's potential exposure to market risk. Market risk
represents the potential loss arising from adverse changes in the value of
financial instruments. The risk of loss is assessed based on the likelihood of
adverse changes in fair values, cash flows or future earnings.

The Company has established guidelines relative to the diversification and
maturities of investments to maintain safety and liquidity. These guidelines are
reviewed periodically and may be modified depending on market conditions.
Although investments may be subject to credit risk, the Company's investment
policy specifies credit quality standards for its investments and limits the
amount of credit exposure from any single issue, issuer or type of investment.
The Company's investments are also subject to interest rate risk and will
decrease in value if market interest rates increase. The Company does not use
derivative instruments for investment or trading purposes. At June 30, 2004, the
Company's market risk sensitive instruments consisted of marketable securities
available for sale and unsecured convertible notes issued by the Company.

MARKETABLE SECURITIES AVAILABLE FOR SALE: At June 30, 2004 the Company's
marketable securities available for sale consisted of U.S. government agency
mortgage obligations, U.S. government agency bonds, corporate debt securities
and Pharmion equity securities, which we obtained in connection with the
conversion of the $12.0 million Pharmion Senior Convertible Promissory Note.
Marketable securities

                                       28


available for sale are carried at fair value, 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 and
other income.

As of June 30, 2004, the principal amounts, fair values and related weighted
average interest rates of the Company's debt securities classified as marketable
securities available-for-sale were as follows:



------------------------------------------------------------------------------------------------------------------------
                                                Fixed rate securities

 Principal amount               $58,543      $178,450        $80,706       $138,275         $47,150          $503,124
 Fair value                     $59,706      $184,331        $80,911       $135,467         $45,318          $505,733
 Average Interest Rate            4.09%         4.73%          4.46%          4.96%           6.98%             4.89%
------------------------------------------------------------------------------------------------------------------------


In March 2004, the Company converted the $12.0 million Pharmion Senior
Convertible Promissory Note, with a principal amount of $12.0 million and
accrued interest of approximately $0.7 million, into 1,150,511 shares of
Pharmion common stock at a conversion price of $11.00 per share. The Pharmion
equity securities investment had a fair value at June 30, 2004 of $56.3 million.
For more information see Note 11 of the Notes to the Consolidated Financial
Statements.

CONVERTIBLE DEBT: At June 30, 2004, the Company had $400.0 million of unsecured
convertible notes outstanding. The notes have a five-year term and a coupon rate
of 1.75% payable semi-annually. The notes can be converted at any time into
8,255,920 shares of common stock at a conversion price of $48.45 per share (for
more information see Note 3 of the Notes to the Consolidated Financial
Statements). At June 30, 2004, the fair value of the Company's convertible notes
exceeded the carrying value of $400.0 million by approximately $142.0 million,
which the Company believes reflects the increase in the market price of the
Company's common stock to $57.26 per share as of June 30, 2004. Assuming other
factors are held constant, an increase in interest rates generally results in a
decrease in the fair value of fixed-rate convertible debt, but does not impact
the carrying value, and an increase in the Company's stock price generally
results in an increase in the fair value of convertible debt, but does not
impact the carrying value.

Item 4 - Controls and Procedures

       (a)  Evaluation of Disclosure Controls and Procedures. Our principal
            executive officer and principal financial officer have concluded
            that our disclosure controls and procedures (as defined in Rule
            13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934,
            as amended), based on their evaluation of these controls and
            procedures as of June 30, 2004, are effective.

       (b)  Changes in Internal Control Over Financial Reporting. There have not
            been any changes in our internal control over financial reporting
            during the fiscal quarter to which this report relates that have
            materially affected, or are reasonably likely to materially affect,
            our internal control over financial reporting.
