   Target Affirmed to Achieve $0.55 Range

SUMMIT, NJ - (NOVEMBER 3, 2005) - CELGENE CORPORATION  (NASDAQ:  CELG) announced
adjusted earnings per diluted share of $0.06 for the quarter ended September 30,
2005. On a reported basis, under U.S. Generally Accepted  Accounting  Principles
(GAAP), Celgene reported net income of $668.0 thousand compared to net income of
$19.0  million,  or earnings of $0.11 per diluted  share in the third quarter of
the prior year.  Total product sales for the third quarter  increased  35.9 % to
$113.9 million from $83.8 million for the prior-year  quarter.  THALOMID(R)  net
sales in the third quarter of 2005  increased  25.9% to $99.1 million from $78.7
million in the third quarter of 2004.  Celgene posted third quarter adjusted net
income  of $10.4  million,  or  adjusted  earnings  of $0.06 per  diluted  share
compared to adjusted net income of $21.2  million or adjusted  earnings of $0.12
per diluted share in the third quarter of last year.

For the nine-month period,  total product sales reached a record $316.9 million,
an  increase  of 32.6%  over the same  period  in 2004.  THALOMID  sales for the
nine-month  period were $281.9  million  compared to $222.5  million in 2004, an
increase of 26.7%  year-over-year.  Celgene posted  adjusted net income of $60.1
million or adjusted  earnings of $0.33 per diluted share,  during the nine-month
period, compared to adjusted net income of $42.2 million or adjusted earnings of
$0.24 per diluted share in the  comparable  2004 period.  During the  nine-month
period on a reported basis,  Celgene  announced GAAP net income of $59.7 million
or  earnings of $0.33 per  diluted  share,  compared to GAAP net income of $30.5
million or earnings of $0.17 per diluted share in the nine-months of last year.

Adjusted net income and per share amounts for the three and  nine-month  periods
ended  September  30,  2005,  eliminate  the effects of charges for  accelerated
depreciation expense related to the Company's corporate headquarters relocation,
charges to record our share of equity losses in EntreMed, Inc. and to adjust the
income tax provision to a projected cash tax rate of 28.0 percent.  Adjusted net
income and per share amounts for the nine-month period ended September 30, 2005,
also excludes the effects of charges recorded for changes in the estimated value
of the Company's  investment in EntreMed,  Inc. warrants which were exercised on
March 31, 2005.

Adjusted or Non-GAAP  financial  measures provide  investors and management with
supplemental  measures  of  operating  performance  and trends  that  facilitate
comparisons  between periods  before,  during and after certain items that would
not  otherwise  be  apparent  on  a  GAAP  basis  because   certain  unusual  or
non-recurring  items that do not affect the Company's  basic  operations also do
not meet the GAAP definition of unusual  non-recurring items.  Adjusted earnings
are not,  and should not be,  viewed as a  substitute  for GAAP net income.  Our
definition of adjusted earnings may differ from others.

To support  clinical  development  and to advance U.S.  and European  regulatory
filings,  Celgene increased R&D expenditures in REVLIMID(R)  regulatory programs
in myelodysplastic syndromes and multiple myeloma. Celgene incurred R&D expenses
of $49.3 million in the third quarter of 2005, representing an increase of 22.9%
compared  to the year ago  quarter.  These  R&D  expenditures  are  expected  to
increase  in the fourth  quarter in support  of our  ongoing  global




   regulatory filings, late stage clinical trials, clinical progress in multiple
   proprietary development programs and related clinical manufacturing costs.

   Selling,  general and administrative expenses were $46.9 million in the third
   quarter of 2005,  a 69.2%  increase  over  third  quarter  last year,  driven
   primarily by higher  marketing and sales  expenses  related to product launch
   activities.  Approximately  $13 million in marketing and sales  expenses,  or
   approximately  $0.07 per  diluted  share,  were spent to  support  pre-launch
   activities  for REVLIMID and  THALOMID,  and  headcount  growth in commercial
   support  groups.  These  marketing  and sales  expenditures  are  expected to
   increase  in the fourth  quarter  2005 as Celgene  optimizes  its  commercial
   launch preparations.

   As of  September  30,  2005,  Celgene  reported  $746.0  million  in cash and
   marketable securities, an increase of $22.3 million versus the prior quarter.

   "We are pleased with the progress of our REVLIMID regulatory  application for
   MDS in the U.S. and Europe  achieved  during the third quarter," said John W.
   Jackson,  Chairman and Chief Executive  Officer of Celgene  Corporation." Our
   commercial  preparations  are  being  finalized  to  ensure  rapid  access to
   REVLIMID upon approval."

   2005 THIRD QUARTER COMPANY HIGHLIGHTS:

   CLINICAL AND REGULATORY ACHIEVEMENTS:
   -------------------------------------

o  The  Oncologic  Drugs  Advisory  Committee  (ODAC) of the U.S.  Food and Drug
   Administration  (FDA) recommended full approval of REVLIMID for the treatment
   of   patients   with   transfusion-dependent    anemia   due   to   low-   or
   intermediate-1-risk   myelodysplastic   syndromes  (MDS)  associated  with  a
   deletion 5q cytogenetic  abnormality with or without  additional  cytogenetic
   abnormalities.  The committee based its  recommendation on clinical data from
   an open label Phase II trial,  evaluating  REVLIMID(R)  in the largest  trial
   with MDS patients  with  deletion 5q  chromosomal  abnormality  to date.  The
   original action date under the Prescription Drug User Fee Act (PDUFA) for the
   REVLIMID  NDA was  extended  from October 7, 2005 to January 7, 2006 to allow
   more time for completion of review of the REVLIMID risk-management program.

o  The  European  Medicines  Agency  (EMEA)  accepted  the  Company's  Marketing
   Authorization  Application (MAA) for REVLIMID for review.  The application is
   based on clinical data from an open-label Phase II trial, evaluating REVLIMID
   in the  largest  clinical  trial to date of MDS  patients  with  deletion  5q
   chromosomal abnormality.  Celgene is seeking authorization to market REVLIMID
   as  a   treatment   for   transfusion-dependent   anemia   due  to   low-  or
   intermediate-1-risk   myelodysplastic   syndromes  (MDS)  associated  with  a
   deletion 5q cytogenetic  abnormality with or without  additional  cytogenetic
   abnormalities.




   CORPORATE AND COMMERCIAL DEVELOPMENTS:
   --------------------------------------

o  The Celgene  management team was further  strengthened by the addition of Mr.
   Aart Brouwer as President of Celgene International,  Sarl based in Neuchatel,
   Switzerland.   Aart  brings  over  30  years  of  global  pharmaceutical  and
   biotechnology   experience   building  successful  major  product  franchises
   throughout  Europe.  Prior to Celgene,  Aart spent 14 years building  Amgen's
   international  business  in Europe.  His  accomplishments  included  building
   subsidiaries  in all of  Europe,  with  Sales,  Marketing  and  high  quality
   Clinical Development organizations.

o  Celgene  contributed  $2 million  in  financial  support  to an  independent,
   non-profit  501(c)(3)  charity  whose  mission is to support the needs of the
   underinsured.  The foundation provides financial support to eligible patients
   suffering from certain diseases.  These patients have insurance coverage, but
   may not be able to  afford  the  out-of-pocket  costs  associated  with  that
   coverage,  which are necessary to obtain prescription drug therapies critical
   to their overall  treatment.  The  foundation,  which is not affiliated  with
   Celgene,  assesses  patients'  eligibility to receive  co-payment  assistance
   based upon its own independent objective eligibility criteria. Celgene has no
   involvement or influence over any patient eligibility  decisions,  and is one
   of many donors to the foundation.

CELGENE CORPORATION
NOTES TO RECONCILIATION OF GAAP EARNINGS TO "ADJUSTED" EARNINGS
THREE MONTHS ENDED SEPTEMBER 30, 2005 AND 2004
(UNAUDITED)
(IN THOUSANDS, EXCEPT PER SHARE DATA)

(1)  To exclude  accelerated  depreciation  expense related to the relocation of
     the Company's corporate headquarters.

(2)  To exclude the Company's  share of equity  losses in EntreMed,  Inc. and to
     adjust for our share of THALOMID royalties payable to EntreMed, Inc.

(3)  To exclude the charge  recorded for changes in the  estimated  value of the
     Company's investment in EntreMed, Inc. warrants prior to our March 31, 2005
     exercise.

(4)  To adjust the income tax  provision  to a projected  cash tax rate of 28.0%
     and  8.7% in 2005  and  2004,  respectively.  The  projected  cash tax rate
     differs from the GAAP  provision  due primarily to (i) The  recognition  of
     deferred  tax assets in the first  quarter of 2005 that  decreased  the tax
     provision  but not cash taxes  (ii) the use of net  operating  losses  that
     arose from employee stock option deductions that reduce cash taxes, but not
     the tax  provision,  (iii) the  exercise of employee  stock  options in the
     current year that reduce cash taxes,  but not the tax  provision,  and (iv)
     the payment in the current  year of prior year taxes,  that  increase  cash
     taxes, but not the tax provision

(5)  For  the  three-month  period  ended  September  30,  2004,  the  Company's
     convertible  debt was  anti-dilutive  on a GAAP  basis but  dilutive  on an
     adjusted basis.  Accordingly,  the weighted-average  shares used to compute
     the  adjusted  diluted  earnings  includes  the  additional  common  shares
     assuming conversion of the convertible debt.

CELGENE CORPORATION
NOTES TO RECONCILIATION OF GAAP EARNINGS TO "ADJUSTED" EARNINGS
NINE MONTHS ENDED SEPTEMBER 30, 2005 AND 2004
(UNAUDITED)
(IN THOUSANDS, EXCEPT PER SHARE DATA)

(1)  To exclude  accelerated  depreciation  expense related to the relocation of
     the Company's corporate headquarters.

(2)  To exclude the Company's  share of equity  losses in EntreMed,  Inc. and to
     adjust for our share of THALOMID royalties payable to EntreMed, Inc.

(3)  To exclude the charge  recorded for changes in the  estimated  value of the
     Company's investment in EntreMed, Inc. warrants prior to our March 31, 2005
     exercise.

(4)  To adjust the income tax  provision  to a projected  cash tax rate of 28.0%
     and  8.7% in 2005  and  2004,  respectively.  The  projected  cash tax rate
     differs from the GAAP  provision  due primarily to (i) The  recognition  of
     deferred  tax assets in the first  quarter of 2005 that  decreased  the tax
     provision  but not cash taxes  (ii) the use of net  operating  losses  that
     arose from employee stock option deductions that reduce cash taxes, but not
     the tax  provision,  (iii) the  exercise of employee  stock  options in the
     current year that reduce cash taxes,  but not the tax  provision,  and (iv)
     the payment in the current  year of prior year taxes,  that  increase  cash
     taxes, but not the tax provision
