ended  December  31,  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 reflect  cash taxes.  Adjusted net income and per share
amounts for the  twelve-month  period ended  December  31, 2005 also  excludes a
charge  recorded  for  changes  in the  estimated  value  of our  investment  in
EntreMed,  Inc.  warrants  prior to our March 31, 2005  exercise.  Adjusted  net

December 31, 2004 excludes  charges  recorded for changes in the estimated value
of our  investment  in  EntreMed,  Inc.  warrants  and to adjust  the income tax
provision to reflect cash taxes.

To further  accelerate  the  progress  of key  late-stage  regulatory  programs,
Celgene  increased  R&D  expenditures  in  REVLIMID(R)  Phase II and  Phase  III
regulatory programs in myelodysplastic syndromes and multiple myeloma, including
the ongoing pivotal Phase III MDS deletion 5q trial to support the Company's MAA
seeking approval to market REVLIMID in Europe.  Celgene incurred R&D expenses of
$52.4  million in the fourth  quarter of 2005,  representing  an increase of 19%
compared to the year ago  quarter.  These R&D  expenditures  continue to support
ongoing  clinical  progress in multiple  proprietary  development  programs  for
THALOMID(R),  REVLIMID,  and for other  immunomodulatory  drugs such as CC-4047,
CC-11006 and CC-10050,  as well as in the TNF alpha, kinase and ligase inhibitor
programs and stem cell program.

Celgene reported $724.3 million in cash and marketable securities as of December
31, 2005.

"In 2005,  we made great  strides  across all areas of Celgene,  and in 2006, we
will  continue to prepare for an  incredibly  promising  future,"  said  Celgene
Chairman  and Chief  Executive  Officer John W.  Jackson.  " We believe that the
REVLIMID transformation is well on its way."

2005 COMPANY HIGHLIGHTS:

CLINICAL, REGULATORY AND DRUG DISCOVERY ACHIEVEMENTS:
- -----------------------------------------------------

o    The U.S. Food and Drug  Administration  (FDA) granted  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.   REVLIMID  is  now  available   through  an  Education  and
     Prescribing Safety Program, called RevAssist(SM) via specialty pharmacies.

o    The  FDA  granted   approval  for  FOCALIN  XR   (dexmethylphenidate   HCl)
     extended-release       capsules       for      the       treatment       of
     Attention-Deficit/Hyperactivity  Disorder (ADHD) in adults, adolescents and
     children. The approval of FOCALIN XR for the treatment of ADHD was based on
     efficacy and safety data from clinical trials involving  approximately  320
     adults, adolescents and children diagnosed with ADHD.

o    The European  Medicines  Agency  (EMEA)  accepted for review the  Company's
     Marketing Authorization  Application (MAA) for REVLIMID. The application is
     based on the same



     clinical data, from an open-label  Phase II trial,  evaluated by the FDA to
     support   its   decision   to  approve   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.

o    Celgene submitted its Supplemental New Drug Application (sNDA) for REVLIMID
     to the Division of Oncology  Drug  Products at the FDA seeking  approval to
     market REVLIMID as a treatment for relapsed or refractory multiple myeloma.

o    Celgene submitted its MAA for REVLIMID to the Swiss Intercantonal Medicines
     Control  Office  seeking  approval 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.

o    The FDA issued an  approvable  letter in  response  to the  Company's  sNDA
     seeking  approval to market  THALOMID as a treatment  for multiple  myeloma
     (MM).  The  FDA  requested  revised  product  labeling  with  the  specific
     indication  of  newly  diagnosed   multiple   myeloma  and  updated  safety
     information, as well as some additional patient information to finalize its
     review.  The Company has completed its response,  and anticipates an action
     by the FDA in the first half of 2006.

o    The  Company  announced  that  an  external   Independent  Data  Monitoring
     Committee analysis of the  multi-centered,  randomized,  placebo-controlled
     phase  III  study  (MM-003)   evaluating   combination   thalidomide   plus
     dexamethasone   versus   dexamethasone   alone  as  induction  therapy  for
     previously untreated multiple myeloma met the pre-specified  p<0.0015 value
     for stopping the trial.  The IDMC found time to disease  progression  - the
     primary  endpoint of this Phase III trial - of 75.7 weeks versus 27.9 weeks
     (p=0.000065),  plus  progression-free  survival  of 55.7 weeks  versus 24.3
     weeks (p=0.0003) in patients receiving THALOMID plus dexamethasone compared
     to patients receiving dexamethasone alone.

o    At  THE  47TH  AMERICAN  SOCIETY  OF  HEMATOLOGY  MEETING  (ASH),  clinical
     investigators  from leading  cancer  research  centers  presented data from
     recent and  on-going  clinical  trials of  THALOMID,  and REVLIMID in broad
     indications, including survival data in multiple myeloma. The presentations
     included  30  abstracts  clinically  evaluating  REVLIMID  in both oral and
     poster  sessions,  including  a plenary  session,  across a broad  range of
     disease indications, as well as 77 abstracts clinically evaluating THALOMID
     in both oral and poster sessions.

o    At the ASH plenary  session,  updated  clinical data were  presented on two
     Phase  III  pivotal  studies  evaluating  REVLIMID  plus  dexamethasone  in
     previously  treated  multiple myeloma  patients.  The updated clinical data
     from the pivotal International Phase III trial (MM-010),  demonstrated that
     the  combination  of REVLIMID  plus  dexamethasone  led to a  statistically
     significant  improvement in median time to disease  progression  (p=0.001).
     The updated  clinical data from the pivotal North  American Phase III trial
     (MM-009),  reported that the combination of REVLIMID(R) plus  dexamethasone
     led to a  statistically  significant  improvement  in overall  survival  in
     addition to a statistically significant improvement in



     median  time to  disease  progression.  As of  June  2005,  median  overall
     survival in patients treated with REVLIMID plus  dexamethasone has not been
     reached as compared to 104 weeks with dexamethasone plus placebo (p=0.013).

o    At  ASH,  clinical  data  from  two  phase  III  studies   evaluating  oral
     combination  THALOMID(R)  reported  survival  advantage  for elderly  newly
     diagnosed   multiple  myeloma  patients.   The  Italian  study  reported  a
     statistically  significant  difference in event-free survival of 68 percent
     versus 32 percent  (p<0.001)  after  twenty-six  months of  treatment  with
     melphalan, prednisone and thalidomide (MPT) versus melphalan and prednisone
     (MP)  alone.  The  French  study  reported  a  significant   difference  in
     progression-free  survival of 73 percent versus 55 percent (p=0.0001) after
     treatment with MPT versus  melphalan and autologous  stem cell  transplant.
     Importantly,  the  study  reported  a  significant  difference  in  overall
     survival that has not been reached after 55 months.

o    At the XXIII Chemotherapy  Foundation Symposium,  preliminary clinical data
     evaluating  THALOMID as an oral  combination  therapy for the  treatment of
     recurrent  epithelial  ovarian  cancer in patients who had  received  prior
     treatments  reported 50% of patients  achieved  overall  response in median
     progression free survival.

CELGENE CORPORATION
NOTES TO RECONCILIATION OF GAAP EARNINGS TO "ADJUSTED" EARNINGS
THREE MONTHS ENDED DECEMBER 31, 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 cash taxes, net of federal refunds
     and payments. The projected cash taxes 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 exercise of employee stock options in the current year that reduce cash
     taxes, but not the tax provision, and (iii) the payment in the current year
     of prior year taxes, that increase cash taxes, but not the tax provision.
