To Our Shareholders:

Incyte’s  rapid  transition  from  a  pure  discovery  company  to  one  that  can 
develop new medicines comes from experience, intellectual discipline and a 
shared focus on fulfi lling unmet medical needs. The rigorous and systematic 
approach to drug discovery and development we have employed over the 
last six years has allowed us to create a diverse product pipeline that includes 
programs in oncology, infl ammation, metabolic disease and HIV.  

The programs that have the greatest near-term potential to create substantial 
and sustained shareholder value are those that are focused on indications 
that we can develop and commercialize independently.  Therefore, our janus-
associated  kinase  inhibitor  (JAK)  program,  which  has  shown  compelling 
early effi cacy results in myelofi brosis, psoriasis, and rheumatoid arthritis, 
is  now  our  highest  priority  program.  In  contrast,  for  programs  that  are 
focused on primary care markets, such as our metabolic disease programs, 
or are outside our core areas of oncology and infl ammation, such as our 
CCR5 antagonist program, our objective is to form strategic partnerships 
at appropriate points in their development, and to use the proceeds from 
these alliances to fund the programs we elect to retain.  

With as many as a dozen Phase II trials expected in 2008, as well as the potential 
initiation of registration trials for myelofibrosis, I believe we are making 
demonstrable progress in building a successful biopharmaceutical company.

2007 Program Achievements 

In 2007, the potential value of the pipeline was substantially enhanced through multiple positive Phase 
IIa proof-of-concept results.   

››  Our lead JAK inhibitor, INCB18424, has demonstrated:

› Unprecedented efficacy in patients with myelofibrosis, a serious neoplastic condition
  characterized by bone marrow failure, life-threatening splenic enlargement and marked
  constitutional symptoms that adversely affect patients’ quality of life; 

›  Compelling early efficacy results in a 28-day trial, comparable to results seen with 
   injectable anti-TNF therapies in patients with rheumatoid arthritis; and

›  Striking improvement in psoriatic skin lesions in a 28-day trial in patients with mild to 
   moderate psoriasis, comparable to a potent topical steroid without the skin atrophy 
   associated with steroid treatment.  

››  Our lead HSD1 inhibitor, INCB13739, completed a 28-day Phase IIa trial in patients with type 
    2 diabetes. Improvements were achieved in six parameters of glucose control and cardiovascular
    risk: fasting plasma glucose, clamp-measured glucose production, clamp-measured glucose
    utilization, LDL cholesterol, total cholesterol, and triglycerides.

››  Our lead HM74a agonist, INCB19602, also for type 2 diabetes, reduced circulating free fatty 
    acids which are associated with insulin desensitization, with no rebound or cutaneous flushing. 
    These results in a Phase I trial with healthy volunteers suggest that INCB19602 could achieve
    similar results in type 2 diabetics.

››  Our sheddase inhibitor, INCB7839, demonstrated improvement in several clinically relevant
    pharmacodynamic markers and produced stable disease in five of six Her2-positive breast 
    cancer patients.

These  encouraging  clinical  results  are  evidence  that  Incyte  is  rapidly  transitioning  from  a  pure  drug-
discovery company into a highly productive drug discovery and development company. As such, it is now 
both realistic and essential that we prioritize our programs.

JAK Inhibitor Program Is Now Our Highest Priority Program 

The success we achieved in 2007 in the JAK inhibitor program for myelofi brosis, a rare life-threatening 
myeloproliferative  disease  for  which  there  are  no  approved  drug  therapies,  is  gratifying.  Importantly, 
based  on  recent  discussions  with  representatives  from  the  U.S.  Food  and  Drug  Administration  (FDA) 
in which we reached agreement on the type of endpoints that will support approval in myelofi brosis, 
I  believe  we  are  well-positioned  to  begin  registration  trials  in  the  fourth  quarter  of  this  year.  As  this 
indication  is  likely  to  receive  expedited  FDA  review,  the  JAK  program  offers  tremendous  potential  for 
creating near-term value. It is a program we can develop and commercialize on our own, and it is now 
our highest priority.    

There also is a growing body of preclinical and clinical evidence suggesting JAK inhibitors may represent 
a new class of drugs to treat other hematological conditions, solid tumors and multiple infl ammatory 
conditions. Given this broad potential, and the fact that we have one of the most advanced compounds 
in clinical development, we are aggressively moving INCB18424 forward in multiple indications.  

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
       
Currently, we are evaluating the oral form of INCB18424 in four Phase II trials: myelofi brosis, multiple 
myeloma, hormone refractory prostate cancer, and rheumatoid arthritis. Phase II trials are also scheduled 
to begin this year for polycythemia vera, essential thrombocythemia and psoriasis. 

In addition to the oral formulation, we have developed a topical formulation of INCB18424 for mild-to-
moderate psoriasis. Clinical results from a 28-day study indicate an exceptionally clean safety profi le and 
impressive effi cacy. This indication is also one we could commercialize on our own and could prove quite 
valuable as we believe we are the only company developing a topical JAK inhibitor.  

INCB28050, our lead follow-on JAK inhibitor, is expected to begin Phase I trials in the fi rst half of this 
year.  If  this  compound  achieves  comparable  pharmacodynamics  and  safety  characteristics  as  our  lead 
compound, we intend to move INCB28050 forward as an oral agent in rheumatoid arthritis and psoriasis, 
and possibly other chronic infl ammatory conditions such as Crohn’s disease. 

Decision to Out-License CCR5 Antagonist Program Confi rms Focus on Near-term Value 

We  have  made  good  progress  advancing  our  CCR5  antagonist,  INCB9471,  as  a  treatment  for  HIV. 
We believe it has potential to become the best-in-class CCR5 antagonist. However, as we prioritize the 
programs in our growing pipeline, it is essential that we focus our resources on those with the greatest 
near-term value. Considering that this program is one of our more expensive, time- and labor-intensive 
efforts, and is now our only HIV product, we have decided not to initiate Phase IIb trials and intend to 
pursue out-licensing options.  

2008 Program Objectives

In the coming year, we expect to make signifi cant and visible progress toward the following 
program objectives:

JAK Inhibitor Program 

INCB18424 for oncology:

››  Begin registration trials in myelofibrosis in the fourth quarter of the year.
››  Present results from the ongoing myelofibrosis Phase I/II trial at the American Society of Clinical
    Oncology and European Hematology Association meetings in June, and the American Society 
    of Hematology meeting in December.  
››  Conduct Phase II trials in:

›  Polycythemia vera and essential thrombocythemia;
›  Multiple myeloma; and, 
›  Hormone refractory prostate cancer.

INCB18424 for infl ammation:

››  Complete a 28-day Phase IIa dose-ranging study in patients with rheumatoid arthritis, and present
    results from this study at the European League Against Rheumatism meeting in June.  
››  Present Phase IIa results using the topical formulation at the European Academy of Dermatology
    and Venereology meeting in September.
››  Begin a Phase IIa study in psoriatic patients with the oral-dosing form of INCB18424. 
››  Begin a three-month Phase IIb study with topical dosing in patients with 
    mild-to-moderate psoriasis.

INCB28050 (follow-on JAK inhibitor):

››  Conduct Phase I trials in healthy volunteers.
››  Begin Phase II trials in rheumatoid arthritis patients. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
HSD1 Inhibitor Program 

INCB13739:

››  Conduct a dose-ranging three-month Phase IIb trial in type 2 diabetics. 
››  Present the 28-day Phase IIa trial results at the American Diabetes Association 
    meeting in June. 

INCB20817 (follow-on HSD1 inhibitor):  

››  Conduct Phase I trials in healthy volunteers.

HM74a Agonist Program

INCB19602:

››  Complete Phase I trials in healthy volunteers.
››  Conduct 28-day fasting plasma glucose Phase IIa trial in type 2 diabetics.

Sheddase Inhibitor Program 

INCB7839: 

››  Conduct a Phase IIa trial in combination with Herceptin® in patients with breast cancer.  

CCR2 Antagonist Program

INCB8696: 

››  Complete Phase I trials in healthy volunteers.

Discovery

››  Advance at least one new oncology program through preclinical development 
    and initiate Phase I trials.  

Remarkable Productivity 

The level of productivity of the entire Incyte team, and the success achieved in so many of our programs 
during  2007,  are  nothing  short  of  remarkable.  With  as  many  as  a  dozen  Phase  II  trials  underway 
and  planned  in  2008,  as  well  as  the  potential  initiation  of  registration  trials  for  our  lead  program  in 
myelofi brosis, this year promises to be at least as dynamic. 

I remain optimistic about our future and fully expect the year ahead to validate our near-term focus on 
oncology and infl ammation – areas where there is clear unmet medical need and tremendous potential 
for value creation.  

Sincerely,

Overview

Incyte  is  a  drug  discovery  and  development  company  focused  on  developing  proprietary  small
molecule  drugs  to  treat  serious  unmet  medical  needs.  We  have  a  pipeline  with  programs  in  oncology,
inflammation,  diabetes  and  human  immunodeficiency  virus  (HIV).

Thus  far  in  our  drug  discovery  and  development  activities,  which  began  in  early  2002,  we  have  filed
twelve  Investigational  New  Drug  Applications  (INDs)  and  have  progressed  eight  internally  developed
proprietary compounds into clinical development. Currently, four of these compounds have advanced into
Phase  II  clinical  trials.  Our  wholly-owned  pipeline  includes  the  following  compounds:

Our productivity in drug discovery is primarily a result of our core competency in medicinal chemistry
which  is  tightly  integrated  with  and  supported  by  an  experienced  team  of  biologists  with  expertise  in
multiple therapeutic areas. As a number of our compounds have progressed into clinical development, we
have  also  built  a  clinical  development  and  regulatory  team.  This  team  utilizes  clinical  research
organizations (CROs), expert scientific advisory boards, and leading consultants and suppliers in relevant
drug development areas in an effort to conduct our clinical trials as efficiently and effectively as possible
while maintaining strategic control of the  design and management of our  programs.

Incyte’s Approach to Drug Discovery  and Development

To  succeed  in  our  objective  to  create  a  pipeline  of  novel,  orally  available  drugs  that  address  serious
unmet medical needs, we have established a broad range of discovery capabilities in-house, including target
validation, high-throughput screening, medicinal chemistry, computational chemistry, and pharmacological
and  ADME  (absorption,  distribution,  metabolism  and  excretion)  assessment.  We  augment  these
capabilities  through  collaborations  with  academic  and  contract  laboratory  resources  with  relevant
expertise.

We  select  drug  targets  with  strong  preclinical  or  clinical  validation  in  areas  where  we  have  the
potential  to  generate  either  first-in-class  molecules  or  compounds  that  are  highly  differentiated  from
existing treatments.

Our chemistry and biology efforts are highly integrated and are characterized by the rapid generation
of relevant data on a broad and diverse range of compounds for each therapeutic target we pursue. This
process  allows  our  scientists  to  better  understand,  in  real  time,  the  potency  and  selectivity  of  the
compounds,  how  they  are  likely  to  be  absorbed  and  eliminated  in  the  body,  and  to  assess  the  potential
safety of the compounds. We believe that this approach, along with stringent criteria for the selection of
clinical candidates, will help us to select appropriate candidates for clinical development and rapidly assess
key characteristics required for success.

Given  our  chemistry-driven  discovery  process,  our  pipeline  has  grown  to  encompass  multiple
therapeutic areas: oncology, inflammation, diabetes and HIV. While our productivity has created a diverse
pipeline, we conduct a limited number of discovery programs in parallel at any one time. This focus allows
us to allocate resources to our selected programs at a level that we believe is competitive with much larger
pharmaceutical  companies.  We  believe  this  level  of  resource  allocation,  applied  to  the  discovery  process
outlined above, has been critical to our success in our current programs, and that it remains a meaningful
competitive advantage.

Additionally,  in  all  of  our  programs  we  strive  to  generate  a  diverse  and  broad  range  of  proprietary
compounds which we believe enhances the overall probability of success for our programs and creates the
potential for multiple products.

Once  our  compounds  reach  clinical  development,  our  objective,  whenever  possible,  is  to  rapidly
progress  the  lead  candidate  into  a  proof-of-concept  clinical  trial  prior  to  initiating  larger  definitive
Phase  IIb  clinical  trials  to  quickly  assess  the  therapeutic  potential  of  the  clinical  candidate  itself  and  its
underlying  mechanism.  This  information  is  then  used  to  evaluate  the  commercial  potential  of  the
compound and the most appropriate  indication or indications to pursue.

Incyte’s Development Teams

Our  development  teams  are  responsible  for  ensuring  that  our  clinical  candidates  are  expeditiously
progressed  from  preclinical  development  and  IND-enabling  studies  into  Phase  I  and  Phase  II
development.  To  efficiently  and  effectively  keep  pace  with  the  growth  in  our  clinical  pipeline,  we  have
added new members to the development teams by internal transfers and by recruiting new employees with
expertise  in  drug  development  including  clinical  trial  design,  statistics,  regulatory  affairs,  and  project

6

management.  We  have  also  built  core  internal  process  chemistry  and  formulation  teams  using  this  same
strategy.  Our  internal  multi-disciplinary  project  teams  also  work  with  experienced  external  CROs  with
expertise  in  managing  clinical  trials,  process  chemistry,  product  formulation,  and  the  manufacture  of
clinical trial supplies to support our drug  development efforts.

Clinical Pipeline

Our  pipeline  includes  compounds  in  various  stages  of  development  in  the  areas  of  oncology,
inflammation,  diabetes  and  HIV.  The  following  summarizes  the  status  of  and  rationale  for  our  most
advanced compounds.

JAK 2 Program for Inflammation, Hematologic Malignancies, and Solid  Tumors

The  JAK  family  is  composed  of  four  tyrosine  kinases—JAK1,  JAK2,  JAK3  and  Tyk2—that  are
involved in signaling triggered by a number of cytokines and growth factors. JAKs are central to a number
of  biologic  processes,  including  the  formation  and  development  of  blood  cells  and  the  regulation  of
immune  functions.  Excessive  signaling  through  the  JAK  pathways  is  believed  to  play  a  critical  role  in  a
number of disease states, including myeloproliferative disorders (MPDs), specifically myelofibrosis (MF),
polycythemia  vera  and  essential  thrombocythemia,  inflammatory  conditions  such  as  rheumatoid  arthritis
(RA)  and  psoriasis,  and  certain  other  solid  and  liquid  tumors.  Additionally,  many  MPD  patients  have  a
mutation that is associated with JAK2, V617F, as well as other JAK2 mutations, which result in increased
JAK signaling and we believe further supports the hypothesis that hyperactivation of the JAK pathways is
central to these disorders. We believe inhibition of aberrant JAK signaling may have therapeutic value in
treating  these various diseases.

We have discovered multiple potent, selective and orally bioavailable JAK inhibitors that are selective
for  JAK1  and  JAK2  from  multiple  distinct  chemical  scaffolds.  Our  lead  JAK  inhibitor,  INCB18424,  is
currently being developed as a treatment for several of these conditions, including MF, RA and psoriasis. A
lead follow-on JAK inhibitor compound,  INCB28050, is expected  to  enter clinical trials in 2008.

Thus  far,  our  clinical  trial  results  with  INCB18424  include  positive  interim  results  from  several

Phase IIa clinical trials in MF, RA and  psoriasis patients and the compound has  been well  tolerated.

Myelofibrosis

In  December  2007,  we  reported  positive  interim  results  involving  11  MF  patients  from  a
dose-escalation  Phase  Ib/IIa  trial  with  orally  administered  INCB18424.  We  also  announced  that  we
reached a maximum tolerated dose in this first Phase Ib/IIa trial and have expanded the study to include an
additional  21  patients  at  this  dose.  If  the  compound  continues  to  be  well  tolerated  and  demonstrates
comparable  efficacy  in  additional  patients,  we  intend  to  begin  discussions  with  the  Food  and  Drug
Administration (FDA) to define the potential registration pathway for INCB18424 as a treatment for MF.
Provided the FDA agrees with our development plan, our objective is to initiate these trials in the second
half of 2008.

Rheumatoid Arthritis

In  January  2008,  we  announced  positive  interim  results  from  a  28-day  Phase  IIa  dose-ranging  trial
using  the  oral  formulation  of  INCB18424  in  six  RA  patients  whose  conditions  were  not  well-controlled
with their existing therapy. This trial is expected to involve a total of 48 patients with final results expected
in the first half of 2008. Provided these results are positive, we plan to begin a six-month Phase IIb trial in
RA patients in the second half of 2008.

7

Psoriasis (Topical)

In  September  2007,  we  announced  positive  interim  results  from  a  28-day  Phase  IIa  dose-escalation
trial  with  topical  INCB18424,  involving  24  patients  with  mild-to-moderate  psoriasis.  In  this  trial  the
compound was well tolerated with no adverse events reported at any dose administered and with rapid and
sustained improvement observed in all subjects. These results suggest that topical intervention in the JAK
pathway could be an effective way to treat psoriasis. If the compound continues to be well tolerated in the
ongoing  safety  studies,  we  expect  to  begin  a  three-month  Phase  IIb  trial  in  psoriasis  using  this  topical
formulation in the second half of 2008.

Refractory Prostate Cancer and Multiple  Myeloma

We recently initiated Phase IIa clinical trials in refractory prostate cancer patients, as well as patients

with multiple myeloma. Results from these trials are expected  in the second half of 2008.

We intend to complete our IND-enabling studies and initiate Phase I clinical trials with our follow-on

JAK inhibitor compound INCB28050  in  mid-2008.

11ßHSD1 Program for Type 2 Diabetes and  Related Disorders

We have developed a broad chemically diverse series of novel proprietary oral inhibitors of 11ßHSD1,
an  enzyme  that  converts  the  biologically-inactive  steroid  cortisone  into  the  potent  biologically-active
hormone  cortisol.  Cortisol  acts  as  a  functional  antagonist  of  insulin  action  in  multiple  tissue  types,
including the liver, adipose, skeletal muscle, and pancreas. Inhibition of 11ßHSD1 offers the potential to
reduce  insulin  resistance  and  restore  glycemic  control  in  type  2  diabetes,  and  may  also  offer  potential
benefits in allied conditions such as dyslipidemia, atherosclerosis, and  coronary heart disease.

In September 2007, we reported positive interim results from the ongoing 28-day Phase IIa placebo-
controlled  clinical  trial  in  type  2  diabetes.  In  the  patients  included  in  this  interim  analysis,  we  observed
positive  effects  on  multiple  clinically  relevant  endpoints  such  as  fasting  plasma  glucose  and  on
dyslipidemia, including reduction of LDL, total cholesterol and triglycerides. A three-month Phase IIb trial
in type 2  diabetes is scheduled to begin  in  the first half of  2008.

For  INCB20817,  our  follow  on  11ßHSD1  compound,  the  Investigational  New  Drug  Application

(IND)  has been accepted and Phase I  trials are  expected to begin in  the first half of  2008.

HM74a for Type 2 Diabetes

HM74a  is  a  G-protein-coupled  receptor  (GPCR)  that  is  expressed  in  adipocytes  (fat  cells).  GPCRs
are a large protein family of transmembrane receptors that sense molecules outside the cell, activate signal
transduction pathways and, ultimately, cellular responses. GPCRs are involved in many diseases, and are
the target of many existing drugs.

Agonism of HM74a by niacin causes a reduction in circulating free fatty acids (FFA). It is known that
elevated  levels  of  FFAs  are  associated  with  an  increase  in  glucose  production  and  a  decrease  in  glucose
uptake which leads to insulin resistance. While oral administration of niacin leads to a decrease in glucose
production and an increase in glucose uptake, niacin treatments cannot be used to treat insulin resistance
in  type  2  diabetics  because  these  compounds  have  very  short  half-lives  that  lead  to  intolerance  and
discomfort such as cutaneous flushing. Additionally, the short half-life of niacin treatments can cause FFA
levels to rebound and actually lead to increased glucose level. In contrast to niacin containing treatments,
our  lead  HM74a  agonist,  INCB19602,  which  is  in  Phase  I  clinical  trials  in  healthy  volunteers,  does  not
appear  to  cause  flushing  and  has  resulted  in  profound  and  sustained  reductions  in  FFA  levels  without
causing  rebound.  We  therefore  believe  an  HM74a  agonist  could  prove  to  be  an  effective  treatment  for
insulin  resistance  in  type  2  diabetics  without  the  adverse  effect  and  limitations  of  niacin  containing

8

treatments.  If  the  results  from  the  Phase  I  trials  continue  to  support  development  of  INCB19602,  we
intend to begin a 28-day Phase IIa clinical  trial  in type 2  diabetics  in the  first  half of 2008.

CCR5 Antagonist Program for HIV

CCR5 is a major chemokine receptor that the HIV virus uses to enter CD4 cells, which are critical to
the human immune system. CCR5 antagonists belong to a new class of antiretrovirals known as HIV entry
inhibitors.  This  new  class  includes  various  experimental  compounds  designed  to  block  cell  surface
receptors, such as CCR5 or CXCR4, as well as other novel compounds that block HIV fusion with the cell
surface. Entry inhibitors work by blocking HIV before the virus enters the cell and begins its replication
process.  In  contrast,  existing  HIV  drugs  such  as  nucleoside  or  nucleotide  reverse  transcriptase  inhibitors
(NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitors work inside the
cell and target the proteins, reverse transcriptases and proteases that are involved in the replication of the
virus.

Our  CCR5  antagonist  program  has  yielded  potent,  selective,  proprietary  compounds  with
pharmacokinetic  properties  that  have  the  potential  to  allow  once-daily  dosing  without  use  of  ritonavir
boosting, a key distinction from other CCR5 antagonists. Ritonavir is a protease inhibitor that is often used
in combination with other drugs to improve or ‘boost’ the bioavailability and cellular penetration of other
drugs  but  which  is  associated  with  increased  cardiovascular  risk.  This  dosing  profile  is  particularly
attractive  in  patients  who  are  in  the  earlier  stages  of  disease,  where  CCR5  is  most  prevalent,  where  the
majority  of  regimens  are  once-daily  (which  improves  patient  compliance),  and  where  ritonavir,  which
increases  the  risk  of  cardiovascular  disease,  is  less  frequently  used.  Once-a-day  dosing  also  offers  the
potential  for  the  development  of  once-daily  fixed  dose  combination  formulations  with  other  anti-HIV
medications.

We have two CCR5 antagonists in development, INCB9471 and INCB15050. INCB9471 is the most
advanced compound in this program. Thus far, from a 14-day Phase IIa clinical trial, we have seen positive
results demonstrating that once-daily dosing with INCB9471 offers sustained inhibition of viral replication.
This suggests that INCB9471 may provide an advantage over other CCR5 antagonists in development and
other  antiretroviral  drugs  that  have  shorter  half-lives,  less  than  24  hours,  especially  in  patients  who  are
intermittently  non-compliant  with  their  medications.  Lack  of  adherence  with  drugs  that  have  short  half
lives can lead to insufficient drug levels, which reduces the effectiveness of the drug regimen and allows the
virus to replicate. We are conducting several required drug interaction studies and completing longer-term
safety  studies  with  INCB9471  to  support  initiation  of  two  Phase  IIb  trials  in  treatment-experienced  HIV
patients.

Our follow-on CCR5 antagonist, INCB15050, has completed Phase I development. While the results
from  the  Phase  I  clinical  trials  suggest  that  INCB15050  also  has  the  potential  to  be  a  potent  once-a-day
treatment,  based  on  the  positive  Phase  IIa  clinical  trial  data  that  we  have  seen  with  the  lead  compound,
INCB9471, we do  not plan to advance  INCB15050 beyond Phase  I  clinical trials  at this time.

Sheddase Inhibitor Program for Solid Tumors

As the fundamental biology of cancer has been explored at the molecular level, new therapeutics are
emerging that distinguish themselves from the classic, relatively non-selective, cytotoxic agents. These new
therapeutics are targeted specifically to pathways or proteins that are more critical for the growth of tumor
cells  than  for  the  growth  of  normal  cells,  thereby  having  the  potential  to  provide  a  greater  therapeutic
benefit, both when used alone and in combination with cytotoxic agents. Currently available therapeutics
of this type have been shown to be effective  in the treatment of certain important tumor types.

The signaling pathways that utilize the receptors and ligands of the epidermal growth factor receptor
(EGFR)  family  play  a  key  role  in  the  growth  and  survival  of  multiple  tumor  types,  including  breast,
colorectal, and non-small cell lung cancers. The EGFR, or HER, signaling pathways consist of four known

9

cellular  receptors:  HER1  (also  known  as  EGFR),  HER2,  HER3,  and  HER4.  Under  normal  conditions,
these  pathways  are  tightly  regulated.  However,  in  cancer,  the  pathways  can  become  dysregulated  and
changes in the amount or the activity of HER family members, primarily HER1, HER2 and HER3, have
been  shown  to  impact  the  growth,  proliferation,  migration,  and  survival  of  cancer  cells.  Sheddase  is  an
enzyme that is believed to activate all four EGFR  pathways.

Currently  approved  therapies  target  one  or  more  of  the  EGFR  pathways.  However,  these  currently
available therapeutics may not block all EGFR family-mediated signaling, even in the tumor types in which
they are approved. In contrast, we believe our sheddase inhibitor targets all four EGFR signaling pathways
and may provide meaningful advantages  over therapies  that target  one or two.

We  have  identified  novel,  potent,  and  orally  available  small-molecule  inhibitors  of  sheddase  that,  in
preclinical models, show efficacy as single agents and show synergy with other targeted therapeutic agents
and  with  cytotoxics.  INCB7839,  the  lead  compound  from  this  program,  is  currently  in  Phase  II
development.  The  first  of  two  Phase  II  trials  has  been  initiated  and  is  designed  to  determine  the
effectiveness  of  INCB7839  when  used  in  combination  with  Herceptin.  A  second  Phase  II  trial  in  breast
cancer patients is planned that will evaluate INCB7839 as  a  monotherapy.

CCR2 Receptor Antagonist Program for  Inflammatory Diseases

CCR2  is  a  key  chemokine  receptor  found  on  monocytes  that  controls  their  migration  into  sites  of
inflammation. Once inside the monocytes differentiate into tissue scavenger cells known as macrophages.
In  their  normal  role,  macrophages  scavenge  foreign  organisms  or  injured  tissues;  however,  excessive  or
inappropriately triggered macrophage activity results in the production of pro-inflammatory mediators that
can  cause  damage  to  tissues  and  can  lead  to  a  chronic  inflammatory  response.  There  is  substantial
preclinical data from multiple academic centers suggesting that CCR2 antagonism could be of therapeutic
benefit  in  multiple  sclerosis  (MS).  Activated  macrophages  accumulate  in  MS  lesions,  where  they  are
associated  with  and  presumed  to  be  required  for  the  destruction  of  the  myelin  sheath,  the  protective
coating  around  the  nerves  which  disrupts  nerve  signaling  and  leads  to  loss  of  muscle  control,  vision,
balance  and  sensation.  Blocking  macrophage  accumulation  at  these  sites  could  thus  lead  to  significant
amelioration of this chronic and debilitating disease.

We  established  a  collaborative  research  and  license  agreement  with  Pfizer  Inc.  (‘‘Pfizer)  in  January
2006  in  which  Pfizer  gained  worldwide  development  and  commercialization  rights  to  our  portfolio  of
CCR2 antagonist compounds. We retained rights to certain CCR2 antagonists for MS and lupus nephritis
and other autoimmune nephritides.

We  are  pursuing  MS  first  given  the  preclinical  evidence  suggesting  that  selective  CCR2  antagonism
has  therapeutic  potential  in  this  disease.  We  have  selected  a  lead  clinical  candidate,  INCB8696,  and
initiated a Phase I clinical trial in healthy  volunteers in  2007.

Discovery

We have a number of early discovery programs at various stages of preclinical testing, including two
lead  clinical  candidates  in  oncology.  We  do  not  typically  disclose  these  programs  and/or  targets  until  we
have successfully completed preclinical toxicology tests with the  lead clinical  candidate.

Commercial Strategy

We  intend  to  develop  and  commercialize  some  of  our  compounds  on  our  own  in  selected  markets
where  we  believe  a  company  of  our  size  can  compete  effectively,  such  as  oncology  and  certain
inflammatory  conditions.  For  programs  that  target  large  primary  care  indications  such  as  diabetes,  or
require  lengthy  and  expensive  clinical  development  plans,  we  intend  to  form  strategic  alliances  with

10

companies that have greater financial and commercial resources than we do, as we did with Pfizer for our
CCR2 antagonist program.

Collaborative Research and License Agreement with Pfizer

Effective in January 2006, we entered a collaborative research and license agreement with Pfizer for
the  pursuit  of  our  CCR2  antagonist  program.  We  received  an  upfront  nonrefundable  payment  of
$40.0 million in January 2006. In addition, we received an aggregate of $20.0 million through the purchase
of convertible subordinated notes, $10.0 million in February 2006 and $10.0 million in October 2007, and
we are eligible to receive additional future development and milestone payments of up to $740.0 million
for the successful development and commercialization of CCR2 antagonists in multiple indications, as well
as royalties on worldwide sales. We received a $3.0 million milestone payment from Pfizer in 2007. Pfizer
gained  worldwide  development  and  commercialization  rights  to  our  portfolio  of  CCR2  antagonist
compounds, the most advanced of which was in Phase IIa clinical trials in rheumatoid arthritis and insulin-
resistant obese patients at the time the agreement became effective in January 2006. Pfizer’s rights extend
to the full scope of potential indications, with the exception of multiple sclerosis and lupus nephritis and
other autoimmune nephritides, for which we retained worldwide rights, along with certain compounds. We
do  not  have  obligations  to  Pfizer  on  preclinical  development  candidates  we  select  for  pursuit  in  these
indications.

Patents and Other Intellectual Property

We regard the protection of patents and other enforceable intellectual property rights that we own or
license as critical to our business and competitive position. Accordingly, we rely on patent, trade secret and
copyright  law,  as  well  as  nondisclosure  and  other  contractual  arrangements,  to  protect  our  intellectual
property. We have established a patent portfolio of owned or in-licensed patents and patent applications
that cover aspects of all our drug candidates, as well as other patents and patent applications that relate to
full-length genes and genomics-related technologies obtained as a result of our past high-throughput gene
sequencing efforts. The patents and patent applications relating to our drug candidates generally include
claims  directed  to  the  drug  candidates,  methods  of  using  the  drug  candidates,  formulations  of  the  drug
candidates, and methods of manufacturing the drug candidates. Our policy is to pursue patent applications
on inventions and discoveries we believe that are commercially important to the development and growth
of our business.

Patents extend for varying periods according to the date of patent filing or grant and the legal term of
patents in the various countries where patent protection is obtained. The actual protection afforded by a
patent, which can vary from country to country, depends on the type of patent, the scope of its coverage
and the availability of legal remedies  in  the country.

We have a number of established patent license agreements relating to our gene patent portfolio and
our genomics-related technology patent portfolio. We are presently receiving royalties and other payments
under certain of our gene and genomics-related patent license agreements. Under our gene patent license
agreements,  we  may  in  the  future  receive  royalties  and  other  payments  if  our  partners  are  successful  in
their efforts to discover drugs and diagnostics under these  license agreements.

We  may  seek  to  license  rights  relating  to  compounds  or  technologies  in  connection  with  our  drug
discovery  and  development  programs.  Under  these  licenses,  we  may  be  required  to  pay  up-front  fees,
license fees, milestone payments and  royalties  on sales of future products.

11

Although  we  believe  our  rights  under  patents  and  patent  applications  provide  a  competitive
advantage, the patent positions of pharmaceutical and biotechnology companies are highly uncertain and
involve  complex  legal  and  factual  questions.  We  may  not  be  able  to  develop  patentable  products  or
processes,  and  may  not  be  able  to  obtain  patents  in  the  United  States  or  elsewhere  from  pending
applications. Even if patent claims are allowed, the claims may not issue, or in the event of issuance, may
not be valid or enforceable or may not be sufficient to protect the technology owned by or licensed to us or
provide us with a competitive advantage. Any patent or other intellectual property rights that we own or
obtain may be circumvented, challenged or invalidated by our competitors. Others may have patents that
relate to our business or technology and that may prevent us from marketing our product candidates unless
we  are  able  to  obtain  a  license  to  those  patents.  In  addition,  litigation  or  other  proceedings  may  be
necessary  to  defend  against  claims  of  infringement,  to  enforce  patents,  to  protect  our  other  intellectual
property rights, to determine the scope and validity of the proprietary rights of third parties or to defend
ourselves  in  patent  or  other  intellectual  property  right  suits  brought  by  third  parties.  We  could  incur
substantial  costs  in  such  litigation  or  other  proceedings.  An  adverse  outcome  in  any  such  litigation  or
proceeding could subject us to significant liability.

With  respect  to  proprietary  information  that  is  not  patentable,  and  for  inventions  for  which  patents
are  difficult  to  enforce,  we  rely  on  trade  secret  protection  and  confidentiality  agreements  to  protect  our
interests.  While  we  require  all  employees,  consultants  and  potential  business  partners  to  enter  into
confidentiality agreements, we may not be able to adequately protect our trade secrets or other proprietary
information.  Others  may  independently  develop  substantially  equivalent  proprietary  information  and
techniques or otherwise gain access to  our trade  secrets.

Competition

Our  drug  discovery  and  development  activities  face,  and  will  continue  to  face,  intense  competition
from organizations such as pharmaceutical and biotechnology companies, as well as academic and research
institutions  and  government  agencies.  Our  major  competitors  include  fully  integrated  pharmaceutical
companies  that  have  extensive  drug  discovery  efforts  and  are  developing  novel  small  molecule
pharmaceuticals.  We  face  significant  competition  from  organizations  that  are  pursuing  pharmaceuticals
that are competitive with our potential  products.

Many  companies  and  institutions,  either  alone  or  together  with  their  collaborative  partners,  have
substantially  greater  financial  resources  and  larger  research  and  development  staffs  than  we  do.  In
addition,  many  competitors,  either  alone  or  together  with  their  collaborative  partners,  have  significantly
greater experience than we do in:

(cid:127) drug discovery;

(cid:127) developing products;

(cid:127) undertaking preclinical testing and clinical trials;

(cid:127) obtaining FDA and other regulatory  approvals of products; and

(cid:127) manufacturing, marketing, distributing and selling products.

Accordingly, our competitors may succeed in obtaining patent protection, receiving FDA approval or
commercializing products before we do. If we commence commercial product sales, we will be competing
against  companies  with  greater  manufacturing,  marketing,  distributing  and  selling  capabilities,  areas  in
which  we have limited or no experience.

12

In addition, any drug candidate that we successfully develop may compete with existing therapies that

have long histories of safe and effective  use. Competition may also arise from:

(cid:127) other  drug  development  technologies  and  methods  of  preventing  or  reducing  the  incidence  of

disease;

(cid:127) new small molecules; or

(cid:127) other classes of therapeutic agents.

Developments by others may render our drug candidates obsolete or noncompetitive. We face and will
continue  to  face  intense  competition  from  other  companies  for  collaborative  arrangements  with
pharmaceutical  and  biotechnology  companies,  for  establishing  relationships  with  academic  and  research
institutions  and  for  licenses  to  proprietary  technology.  These  competitors,  either  alone  or  with  their
collaborative partners, may succeed in  developing  products that  are  more effective than ours.

Our ability to compete successfully will  depend, in  part,  on our ability to:

(cid:127) develop proprietary products;

(cid:127) develop  and  maintain  products  that  reach  the  market  first,  are  technologically  superior  to  and/or

are of lower cost than other products in the  market;

(cid:127) attract and retain scientific and product  development personnel;

(cid:127) obtain patent or other proprietary protection  for  our  products and  technologies;

(cid:127) obtain required regulatory approvals; and

(cid:127) manufacture, market, distribute and sell any  products that we develop.

In a number of countries, including in particular, developing countries, government officials and other
groups have suggested that pharmaceutical companies should make drugs available at a low cost. In some
cases,  governmental  authorities  have  indicated  that  where  pharmaceutical  companies  do  not  do  so,  their
patents might not be enforceable to prevent generic competition. Some major pharmaceutical companies
have  greatly  reduced  prices  for  their  drugs  in  certain  developing  countries.  If  certain  countries  do  not
permit enforcement of any of our patents, sales of our products in those countries, and in other countries
by  importation  from  low-price  countries,  could  be  reduced  by  generic  competition  or  by  parallel
importation  of  our  product.  Alternatively,  governments  in  those  countries  could  require  that  we  grant
compulsory  licenses  to  allow  competitors  to  manufacture  and  sell  their  own  versions  of  our  products  in
those  countries,  thereby  reducing  our  product  sales,  or  we  could  respond  to  governmental  concerns  by
reducing  prices  for  our  products.  In  all  of  these  situations,  our  results  of  operations  could  be  adversely
affected.

Government Regulation

Our related ongoing research and development activities and any manufacturing and marketing of our
potential small molecule products to treat major medical conditions are subject to extensive regulation by
numerous  governmental  authorities  in  the  United  States  and  other  countries.  Before  marketing  in  the
United States, any drug developed by us must undergo rigorous preclinical testing and clinical trials and an
extensive regulatory clearance process implemented by the FDA under the United States Food, Drug and
Cosmetic  Act.  The  FDA  regulates,  among  other  things,  the  development,  testing,  manufacture,  safety,
efficacy, record-keeping, labeling, storage, approval, advertising, promotion, sale and distribution of these
products.  None  of  our  drug  candidates  has,  to  date,  been  submitted  for  approval  for  sale  in  the  United
States  or  any  foreign  market.  The  regulatory  review  and  approval  process,  which  includes  preclinical
testing  and  clinical  trials  of  each  drug  candidate,  is  lengthy,  expensive  and  uncertain.  Securing  FDA
approval requires the submission of extensive preclinical and clinical data and supporting information to

13

the FDA for each indication to establish a drug candidate’s safety and efficacy. The approval process takes
many  years,  requires  the  expenditure  of  substantial  resources,  involves  post-marketing  surveillance  and
may involve ongoing requirements for post-marketing studies. Before commencing clinical investigations in
humans,  we  must  submit  to,  and  receive  approval  from,  the  FDA  of  an  IND  application.  The  steps
required before a drug may be marketed in the United States include:

(cid:127) preclinical laboratory tests, animal  studies and formulation studies;

(cid:127) submission to the FDA of an IND for human clinical testing, which must become effective before

human clinical trials may commence;

(cid:127) adequate  and  well-controlled  clinical  trials  in  three  phases,  as  described  below,  to  establish  the

safety and efficacy of the drug for each indication;

(cid:127) submission  to  the  FDA  of  a  new  drug  application,  or  NDA,  which  must  become  effective  before

marketing can commence;

(cid:127) satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the

drug is produced to assess compliance with  current good manufacturing  practices; and

(cid:127) FDA review and approval of the NDA.

Similar  requirements  exist  within  many  foreign  agencies  as  well.  The  time  required  to  satisfy  FDA
requirements  or  similar  requirements  of  foreign  regulatory  agencies  may  vary  substantially  based  on  the
type, complexity and novelty of the product or the targeted disease.

Preclinical  testing  includes  laboratory  evaluation  of  product  chemistry,  toxicity  and  formulation,  as
well  as  animal  studies.  The  results  of  the  preclinical  tests,  together  with  manufacturing  information  and
analytical data, are submitted to the FDA as part of an IND. An IND will automatically become effective
30  days  after  receipt  by  the  FDA,  unless  before  that  time,  the  FDA  raises  concerns  or  questions  about
issues such as the conduct of the clinical trials as outlined in the IND. In the latter case, the IND sponsor
and the FDA must resolve any outstanding FDA concerns or questions before clinical trials can proceed.
We cannot be sure that submission of an IND will result in the FDA allowing clinical trials to commence.

Clinical  trials  involve  the  administration  of  the  investigational  drug  to  human  subjects  under  the
supervision of qualified investigators. Clinical trials are conducted under protocols detailing the objectives
of the study, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated.
Each  protocol  must  be  submitted  to  the  FDA  as  part  of  the  IND  and  each  trial  must  be  reviewed  and
approved by an independent ethics committee  or institutional review  board  (IRB)  before  it can begin.

Clinical  trials  typically  are  conducted  in  three  sequential  phases,  but  the  phases  may  overlap  or  be
combined.  Phase  I  usually  involves  the  initial  introduction  of  the  investigational  drug  into  healthy
volunteers to evaluate its safety, dosage tolerance, absorption, metabolism, distribution and excretion, and,
if possible, to gain an early indication of its effectiveness. Phase II usually involves clinical trials in a limited
patient population to:

(cid:127) evaluate dosage tolerance and optimal dosage;

(cid:127) identify possible adverse effects and safety  risks; and

(cid:127) evaluate and gain preliminary evidence of the  efficacy  of  the drug for specific indications.

Phase  III  clinical  trials  usually  further  evaluate  clinical  efficacy  and  safety  by  testing  the  drug  in  its
final  form  in  an  expanded  patient  population,  providing  statistical  evidence  of  efficacy  and  safety  and
providing an adequate basis for physician labeling. We cannot guarantee that Phase I, Phase II or Phase III
testing will be completed successfully within any specified period of time, if at all. Furthermore, we or the
FDA  may  suspend  clinical  trials  at  any  time  on  various  grounds,  including  a  finding  that  the  subjects  or
patients are being exposed to an unacceptable  health risk.

14

Even after initial FDA approval has been obtained, further studies, including post-approval trials, may
be  required  to  provide  additional  data  on  safety  and  will  be  required  to  gain  approval  for  the  sale  of  a
product as a treatment for clinical indications other than those for which the product was initially tested
and approved. Also, the FDA will require post-approval reporting to monitor the side effects of the drug.
Results of post-approval programs may limit or expand the indications for which the drug product may be
marketed.  Further,  if  there  are  any  requests  for  modifications  to  the  initial  FDA  approval  for  the  drug,
including  changes 
labeling  or  manufacturing  facilities,  a
supplemental NDA may be required to be submitted to the FDA.

indication,  manufacturing  process, 

in 

Clinical  trials  must  meet  requirements  for  IRB  oversight,  informed  consent  and  good  clinical
practices.  Clinical  trials  must  be  conducted  under  FDA  oversight.  Before  receiving  FDA  clearance  to
market  a  product,  we  must  demonstrate  that  the  product  is  safe  and  effective  for  the  patient  population
that will be treated. If regulatory clearance of a product is granted, this clearance will be limited to those
disease states and conditions for which the product is safe and effective, as demonstrated through clinical
trials. Marketing or promoting a drug for an unapproved indication is prohibited. Furthermore, clearance
may entail ongoing requirements for post-marketing studies. Even if this regulatory clearance is obtained,
a marketed product, its manufacturer and its manufacturing facilities are subject to continual review and
periodic inspections by the FDA. Discovery of previously unknown problems with a product, manufacturer
or  facility  may  result  in  restrictions  on  this  product,  manufacturer  or  facility,  including  costly  recalls  or
withdrawal of the product from the market.

The length of time and related costs necessary to complete clinical trials varies significantly and may
be difficult to predict. Clinical results are frequently susceptible to varying interpretations that may delay,
limit or prevent regulatory approvals. Additional factors that can cause delay or termination of our clinical
trials, or cause the costs of these clinical trials to increase, include:

(cid:127) slow patient enrollment due to the nature of the protocol, the proximity of patients to clinical sites,
the  eligibility  criteria  for  the  study,  competition  with  clinical  trials  for  other  drug  candidates  or
other factors;

(cid:127) inadequately  trained  or  insufficient  personnel  at  the  study  site  to  assist  in  overseeing  and

monitoring clinical trials;

(cid:127) delays in approvals from a study site’s IRB;

(cid:127) longer  than  anticipated  treatment  time  required  to  demonstrate  effectiveness  or  determine  the

appropriate product dose;

(cid:127) lack of sufficient supplies of the drug  candidate for use in clinical trials;

(cid:127) adverse medical events or side effects in treated patients; and

(cid:127) lack of effectiveness of the drug candidate being tested.

Any  drug  is  likely  to  produce  some  toxicities  or  undesirable  side  effects  in  animals  and  in  humans
when  administered  at  sufficiently  high  doses  and/or  for  sufficiently  long  periods  of  time.  Unacceptable
toxicities  or  side  effects  may  occur  at  any  dose  level,  and  at  any  time  in  the  course  of  animal  studies
designed to identify unacceptable effects of a drug candidate, known as toxicological studies, or in clinical
trials of our potential products. The appearance of any unacceptable toxicity or side effect could cause us
or regulatory authorities to interrupt, limit, delay or abort the development of any of our drug candidates,
and  could  ultimately  prevent  their  marketing  clearance  by  the  FDA  or  foreign  regulatory  authorities  for
any or all targeted indications.

The  FDA’s  fast  track  program  is  intended  to  facilitate  the  development  and  expedite  the  review  of
drug candidates intended for the treatment of serious or life-threatening diseases and that demonstrate the
potential  to  address  unmet  medical  needs  for  these  conditions.  Under  this  program,  the  FDA  can,  for

15

example, review portions of an NDA for a fast track product before the entire application is complete, thus
potentially beginning the review process at an  earlier time.

We cannot guarantee that the FDA will grant any of our requests for fast track designation, that any
fast track designation would affect the time of review or that the FDA will approve the NDA submitted for
any of our drug candidates, whether or not fast track designation is granted. Additionally, FDA approval of
a  fast  track  product  can  include  restrictions  on  the  product’s  use  or  distribution  (such  as  permitting  use
only for specified medical procedures or limiting distribution to physicians or facilities with special training
or  experience).  Approval  of  fast  track  products  can  be  conditioned  on  additional  clinical  trials  after
approval.

FDA  procedures  also  provide  for  priority  review  of  NDAs  submitted  for  drugs  that,  compared  to
currently marketed products, offer a significant improvement in the treatment, diagnosis or prevention of a
disease.  The  FDA  seeks  to  review  NDAs  that  are  granted  priority  status  more  quickly  than  NDAs  given
standard status. The FDA’s stated policy is to act on 90% of priority NDAs within six months of receipt.
Although the FDA historically has not met these goals, the agency has made significant improvements in
the timeliness of the review process.

We and any of our contract manufacturers are also required to comply with applicable FDA current
good manufacturing practice regulations. Good manufacturing practices include requirements relating to
quality  control  and  quality  assurance  as  well  as  to  corresponding  maintenance  of  records  and
documentation. Manufacturing facilities are subject to inspection by the applicable regulatory authorities.
These facilities, whether our own or our contract manufacturers, must be approved before we can use them
in commercial manufacturing of our related products. We or our contract manufacturers may not be able
to comply with applicable good manufacturing practices and FDA or other regulatory requirements. If we
or our contract manufacturers fail to comply, we or our contract manufacturers may be subject to legal or
regulatory action, such as suspension of manufacturing, seizure of product, or voluntary recall of product.
Furthermore,  continued  compliance  with  applicable  good  manufacturing  practices  will  require  continual
expenditure  of  time,  money  and  effort  on  the  part  of  us  or  our  contract  manufacturers  in  the  areas  of
production and quality control and record keeping  and  reporting, in order to ensure full compliance.

Outside the United States, our ability to market a product is contingent upon receiving a marketing
authorization  from  the  appropriate  regulatory  authorities.  The  requirements  governing  the  conduct  of
clinical trials, marketing authorization, pricing and reimbursement vary widely from country to country. At
present, foreign marketing authorizations are applied for at a national level, although within the European
Union, or EU, regional registration procedures are available to companies wishing to market a product in
more than one EU member state. If the regulatory authority is satisfied that adequate evidence of safety,
quality and efficacy has been presented, a marketing authorization may be granted. This foreign regulatory
approval  process  involves  all  of  the  risks  associated  with  FDA  approval  discussed  above  and  may  also
include additional risks.

Incyte’s Transition into Small-Molecule Drug Discovery and  Development

Before  the  completion  of  our  transition  into  a  drug  discovery  and  development  company,  we
marketed and sold access to our genomic information databases. However, in recent years, consolidation
within  the  pharmaceutical  and  biotechnology  sectors  and  a  challenging  economic  environment  led  to
reduced  demand  for  research  tools  and  services.  This  trend,  together  with  the  public  availability  of
genomic  information,  significantly  reduced  the  market  for  and  revenues  from,  our  information  products.

On  February  2,  2004,  we  announced  substantial  changes  in  our  information  products  operations,
including  the  closure  of  our  Palo  Alto,  California  facility  and  the  cessation  of  development  of  the
information  products  developed  at  this  facility.  In  January  2005,  we  sold  certain  assets  and  liabilities
related to our Proteome facility based in Beverly, Massachusetts. We no longer have any activities in the

16

information products area. However, we retain certain existing licenses and licensing activities related to
the intellectual property portfolio generated prior  to  the transition.

Research and Development

Since our inception, we have made substantial investments in research and technology development.
During  2007,  2006  and  2005,  we  incurred  research  and  development  expenses  of  $104.9  million,
$87.6 million and $95.6 million, respectively.

Human Resources

As of December 31, 2007, we had 196 employees, including 158 in research and development and 38
in  operations  support,  finance  and  administrative  positions.  Of  these  employees,  74  employees  have
advanced  technical  degrees  including  8  MD’s  and  66  Ph.D’s.  None  of  our  employees  are  covered  by
collective bargaining agreements, and management considers relations with  our  employees to be good.

Item 1A. Risk Factors

RISKS RELATING TO OUR BUSINESS

We are at the early stage of our drug discovery and development efforts and we may be unsuccessful in our
efforts.

We are in the early stage of building our drug discovery and development operations. Our ability to

discover, develop, and commercialize pharmaceutical products will depend on our  ability to:

(cid:127) hire and retain key scientific employees;

(cid:127) identify high quality therapeutic targets;

(cid:127) identify potential drug candidates;

(cid:127) develop products internally or license drug candidates from others;

(cid:127) identify and enroll suitable human subjects, either in the United States or abroad, for our clinical

trials;

(cid:127) complete laboratory testing and clinical trials on humans;

(cid:127) obtain and maintain necessary intellectual property rights to our products;

(cid:127) obtain and maintain necessary regulatory approvals for our products, both in the United States and

abroad;

(cid:127) enter  into  arrangements  with  third  parties  to  provide  services  or  to  manufacture  our  products  on

our  behalf;

(cid:127) deploy  sales  and  marketing  resources  effectively  or  enter  into  arrangements  with  third  parties  to

provide these functions;

(cid:127) lease facilities at reasonable rates to  support our growth;  and

(cid:127) enter into arrangements with third parties  to  license and commercialize our products.

We have limited experience with the activities listed above and may not be successful in discovering,

developing, or commercializing drug products.

Our efforts to discover and develop potential drug candidates may not lead to the discovery, development,
commercialization or marketing of drug  products.

Our  drug  candidates  in  clinical  trials  are  in  early  stage  Phase  I  and  Phase  II  trials.  Our  other  drug
candidates are still undergoing preclinical testing. We have also licensed to Pfizer our portfolio of CCR2
antagonist  compounds.  We  have  no  control  over  the  further  clinical  development  of  any  compounds  we
licensed  to  Pfizer.  Discovery  and  development  of  potential  drug  candidates  are  expensive  and
time-consuming, and we do not know if our efforts will lead to discovery of any drug candidates that can be
successfully  developed  and  marketed.  If  our  efforts  do  not  lead  to  the  discovery  of  a  suitable  drug
candidate, we may be unable to grow our clinical pipeline or we may be unable to enter into agreements
with collaborators who are willing to develop our drug candidates. Of the compounds that we identify as
potential drug products or that we in-license from other companies, only a few, if any, are likely to lead to
successful drug development programs. For example, in 2006, we discontinued the development of DFC,
which  was  at  the  time  our  most  advanced  drug  candidate  and  was  in  Phase  IIb  clinical  trials.  Prior  to
discontinuation  of  the  DFC  program,  we  expended  a  significant  amount  of  effort  and  money  on  that
program.

18

The  success  of  our  drug  discovery  and  development  efforts  may  depend  on  our  ability  to  find  suitable
collaborators to fully exploit our capabilities. If we are unable to establish collaborations or if these future
collaborations are unsuccessful, our research and development efforts may be unsuccessful, which could
adversely affect our results of operations and  financial condition.

An  important  element  of  our  business  strategy  will  be  to  enter  into  collaborative  or  license
arrangements  with  other  parties,  such  as  our  collaboration  with  Pfizer,  under  which  we  license  our  drug
candidates  to  those  parties  for  development  and  commercialization.  We  expect  that  while  we  plan  to
conduct  initial  clinical  trials  on  our  drug  candidates,  we  may  need  to  seek  collaborators  for  our  drug
candidates  such  as  our  chemokine  receptor  antagonists  because  of  the  expense,  effort  and  expertise
required to continue additional clinical trials and further develop those drug candidates. We may also seek
collaborators for our drug candidates that target large primary care indications such as diabetes because of
the  expense  involved  in  further  clinical  development  of  these  indications  and  in  establishing  a  sales  and
marketing organization to address these indications. Because collaboration arrangements are complex to
negotiate, we may not be successful in our attempts to establish these arrangements. Also, we may not have
drug compounds that are desirable to other parties, or we may be unwilling to license a drug compound
because  the  party  interested  in  it  is  a  competitor.  The  terms  of  any  such  arrangements  that  we  establish
may  not  be  favorable  to  us.  Alternatively,  potential  collaborators  may  decide  against  entering  into  an
agreement  with  us  because  of  our  financial,  regulatory  or  intellectual  property  position  or  for  scientific,
commercial or other reasons. If we are not able to establish collaborative agreements, we may not be able
to develop and commercialize a drug product, which would adversely affect our business and our revenues.

In order for any of these collaboration or license arrangements to be successful, we must first identify
potential collaborators or licensees whose capabilities complement and integrate well with ours. We may
rely  on  these  arrangements  for  not  only  financial  resources,  but  also  for  expertise  or  economies  of  scale
that we expect to need in the future relating to clinical trials, manufacturing, sales and marketing, and for
licenses to technology rights. However, it is likely that we will not be able to control the amount and timing
of  resources  that  our  collaborators  or  licensees  devote  to  our  programs  or  potential  products.  If  our
collaborators or licensees prove difficult to work with, are less skilled than we originally expected or do not
devote  adequate  resources  to  the  program,  the  relationship  will  not  be  successful.  If  a  business
combination  involving  a  collaborator  or  licensees  and  a  third  party  were  to  occur,  the  effect  could  be  to
diminish, terminate or cause delays in  development of a potential product.

We face significant competition for our drug discovery and development efforts, and if we do not compete
effectively, our commercial opportunities  will be reduced or eliminated.

The biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and
significant  technological  change.  Our  drug  discovery  and  development  efforts  may  target  diseases  and
conditions  that  are  already  subject  to  existing  therapies  or  that  are  being  developed  by  our  competitors,
many of which have substantially greater resources, larger research and development staffs and facilities,
more  experience  in  completing  preclinical  testing  and  clinical  trials,  and  formulation,  marketing  and
manufacturing capabilities. As a result of these resources, our competitors may develop drug products that
render our products obsolete or noncompetitive by developing more effective drugs or by developing their
products more efficiently. Our ability to develop competitive products would be limited if our competitors
succeeded in obtaining regulatory approvals for drug candidates more rapidly than we were able to or in
obtaining patent protection or other intellectual property rights that limited our drug development efforts.
Any drugs resulting from our research and development efforts, or from our joint efforts with collaborators
or licensees, might not be able to compete successfully with our competitors’ existing and future products,
or obtain regulatory approval in the United  States  or elsewhere.

We depend on our collaboration with Pfizer for the development and commercialization of CCR2 antagonist
compounds.

Under  our  collaborative  research  and  license  agreement  with  Pfizer,  Pfizer  gained  worldwide
development and commercialization rights to our portfolio of CCR2 antagonist compounds. Pfizer’s rights
extend to the full scope of potential indications, with the exception of multiple sclerosis and autoimmune
nephritides.

Although  Pfizer  is  required  to  use  commercially  reasonable  efforts  to  develop  and  commercialize
CCR2  antagonists  for  the  indications  for  which  they  are  responsible,  we  cannot  control  the  amount  and
timing of resources Pfizer may devote to the development of CCR2 antagonists. Any failure of Pfizer to
perform  its  obligations  under  our  agreement  could  negatively  impact  the  development  of  CCR2
antagonists,  lead  to  our  loss  of  potential  revenues  from  product  sales  and  milestones  and  delay  our
achievement, if any, of profitability.

Pfizer  has  certain  rights  to  terminate  the  license  agreement,  including  the  right  to  terminate  upon
90 days’ notice for any reason. Pfizer also has the right to terminate its rights and obligations with respect
to  certain  indications.  If  Pfizer  terminates  the  license  agreement  or  its  rights  with  respect  to  certain
indications,  we  may  not  be  able  to  find  a  new  collaborator  to  replace  Pfizer,  and  our  business  could  be
adversely affected.

If  conflicts  arise  between  our  collaborators,  including  Pfizer,  licensees,  or  advisors  and  us,  our
collaborators, licensees, or advisors may act in their self-interest, which may adversely affect our business.

If  conflicts  arise  between  us  and  our  collaborators  or  licensees,  including  Pfizer,  or  our  scientific
advisors, the other party may act in its self-interest and not in the interest of our stockholders. Conflicts
may arise with our collaborators or licensees if they pursue alternative technologies or develop alternative
products either on their own or in collaboration with others as a means for developing treatments for the
diseases  that  we  have  targeted.  Competing  products,  either  developed  by  these  future  collaborators  or
licensees or to which these future collaborators or licensees have rights, may result in their withdrawal of
support for our product candidates.

Additionally,  conflicts  may  arise  if  there  is  a  dispute  about  the  achievement  and  payment  of  a
milestone  amount  or  the  ownership  of  intellectual  property  that  is  developed  during  the  course  of  the
relationship. Similarly, the parties to a collaboration or license agreement may disagree as to which party
owns newly developed products. Should an agreement be terminated as a result of a dispute and before we
have realized the benefits of the collaboration or license, our reputation could be harmed and we may not
obtain revenues that we anticipated receiving.

We  have  limited  expertise  with  and  capacity  to  conduct  preclinical  testing  and  clinical  trials,  and  our
resulting  dependence  on  other  parties  could  result  in  delays  in  and  additional  costs  for  our  drug
development efforts.

trials, 

We  have  only 

limited  experience  with  clinical 

formulation,  manufacturing  and
commercialization  of  drug  products.  We  also  have  limited  internal  resources  and  capacity  to  perform
preclinical  testing  and  clinical  trials.  As  a  result,  we  intend  to  hire  Clinical  Research  Organizations,  or
CROs,  to  perform  preclinical  testing  and  clinical  trials  for  drug  candidates.  If  the  CROs  that  we  hire  to
perform our preclinical testing and clinical trials or our collaborators or licensees do not meet deadlines,
do not follow proper procedures, or a conflict arises between us and our CROs, our preclinical testing and
clinical trials may take longer than expected, may be delayed or may be terminated. If we were forced to
find a replacement entity to perform any of our preclinical testing or clinical trials, we may not be able to
find  a  suitable  entity  on  favorable  terms,  or  at  all.  Even  if  we  were  able  to  find  another  company  to
perform a preclinical test or clinical trial, the delay in the test or trial may result in significant expenditures.
Events such as these may result in delays in our obtaining regulatory approval for our drug candidates or

20

our ability to commercialize our products and could result in increased expenditures that would adversely
affect our operating results.

In  addition,  for  some  of  our  drug  candidates,  we  plan  to  contract  with  collaborators  or  licensees  to
advance  those  candidates  through  later-stage,  more  expensive  clinical  trials,  rather  than  invest  our  own
resources  to  perform  these  clinical  trials.  Depending  on  the  terms  of  our  agreements  with  these
collaborators or licensees, we may not have any control over the conduct of these clinical trials, and in any
event we would be subject to the risks associated with depending on collaborators or licensees to develop
these drug candidates.

If  we  fail  to  enter  into  additional  licensing  agreements  or  if  these  arrangements  are  unsuccessful,  our
business  and operations might be adversely affected.

In addition to establishing collaborative or license arrangements under which other parties license our
drug candidates for development and commercialization, we intend to continue to explore opportunities to
develop our clinical pipeline by in-licensing drug compounds that fit within our expertise and research and
development capabilities. We may be unable to enter into any additional in-licensing agreements because
suitable  product  candidates  that  are  within  our  expertise  may  not  be  available  to  us  on  terms  that  are
acceptable  to  us  or  because  competitors  with  greater  resources  seek  to  in-license  the  same  product
candidates. Product candidates that we would like to develop may not be available to us because they are
controlled by competitors who are unwilling to license the rights to the drug compound or candidate to us.
In addition, we may enter into license agreements that are unsuccessful and our business and operations
might be adversely affected by the termination of a drug candidate and termination and winding down of
the  related  license  agreement.  For  example,  in  April  2006,  we  announced  the  discontinuation  of
development  of  DFC  and  we  gave  notice  of  termination  of  our  collaborative  license  agreement  with
Pharmasset, Inc., which licensed DFC to us. DFC was at the time our most advanced drug candidate. We
may  also  need  to  license  drug  delivery  or  other  technology  in  order  to  continue  to  develop  our  drug
candidate pipeline. If we are unable to enter into additional agreements to license drug candidates, drug
delivery  technology  or  other  technology  or  if  these  arrangements  are  unsuccessful,  our  research  and
development efforts could be adversely  affected.

If we are unable to obtain regulatory approval to develop and market products in the United States and
foreign jurisdictions, we will not be permitted to manufacture or commercialize products resulting from our
research.

In order to manufacture and commercialize drug products in the United States, our drug candidates
will have to obtain regulatory approval from the Food and Drug Administration, or the FDA. Satisfaction
of  regulatory  requirements  typically  takes  many  years.  To  obtain  regulatory  approval,  we  must  first  show
that  our  drug  products  are  safe  and  effective  for  target  indications  through  preclinical  testing  (animal
testing) and clinical trials (human testing). Preclinical testing and clinical development are long, expensive
and uncertain processes, and we do not know whether the FDA will allow us to undertake clinical trials of
any potential drug products in addition  to  our  compounds currently in clinical trials.

Completion of clinical trials may take several years and failure may occur at any stage of testing. The
length of time required varies substantially according to the type, complexity, novelty and intended use of
the product candidate. Interim results of a preclinical test or clinical trial do not necessarily predict final
results,  and  acceptable  results  in  early  clinical  trials  may  not  be  repeated  in  later  clinical  trials.  For
example, a drug candidate that is successful at the preclinical level may cause harmful or dangerous side
effects when tested at the clinical level. Our rate of commencement and completion of clinical trials may
be delayed by many factors, including:

(cid:127) the high degree of risk associated with drug development;

(cid:127) our inability to formulate or manufacture sufficient quantities of materials for use in clinical trials;

21

(cid:127) variability in the number and types of  patients available  for each study;

(cid:127) difficulty in maintaining contact with  patients after treatment,  resulting in  incomplete data;

(cid:127) unforeseen safety issues or side effects;

(cid:127) poor or unanticipated effectiveness of  drug candidates during the clinical trials; or

(cid:127) government or regulatory delays.

Data obtained from clinical trials are susceptible to varying interpretation, which may delay, limit or
prevent  regulatory  approval.  A  number  of  companies  in  the  pharmaceutical  industry,  including
biotechnology companies, have suffered significant setbacks in advanced clinical trials, even after achieving
promising results in earlier clinical trials. In addition, regulatory authorities may refuse or delay approval
as a result of other factors, such as changes in regulatory policy during the period of product development
and  regulatory  agency  review.  For  example,  the  FDA  has  in  the  past  required  and  could  in  the  future
require  that  we  conduct  additional  trials  of  any  of  our  product  candidates,  which  would  result  in  delays.

Due, in part, to the early stage of our drug candidate research and development process, we cannot
predict whether regulatory approval will be obtained for any product we develop. Our drug candidates in
clinical trials are in early stage Phase I and Phase II trials. Our other drug candidates are still undergoing
preclinical testing. We have also licensed to Pfizer our portfolio of CCR2 antagonist compounds. We have
no  control  over  the  further  clinical  development  of  any  compounds  we  licensed  to  Pfizer.  Compounds
developed by us, alone or with other parties, may not prove to be safe and effective in clinical trials and
may  not  meet  all  of  the  applicable  regulatory  requirements  needed  to  receive  marketing  approval.  If
regulatory  approval  of  a  product  is  granted,  this  approval  will  be  limited  to  those  disease  states  and
conditions for which the product is demonstrated through clinical trials to be safe and effective. Failure to
obtain regulatory approval would delay  or  prevent us  from commercializing  products.

Outside the United States, our ability to market a product is contingent upon receiving a marketing
authorization  from  the  appropriate  regulatory  authorities.  This  foreign  regulatory  approval  process
typically includes all of the risks associated with the FDA approval process described above and may also
include additional risks.

Our  reliance  on  other  parties  to  manufacture  our  drug  candidates  could  result  in  a  short  supply  of  the
drugs,  delays  in  clinical  trials  or  drug  development,  increased  costs  and  withdrawal  or  denial  of  the
regulatory authority’s approval.

We do not currently operate manufacturing facilities for clinical or commercial production of our drug
candidates. We expect to continue to rely on third parties for the manufacture of our drug candidates and
any drug products that we may develop. The FDA requires that drug products be manufactured according
to its current Good Manufacturing Practices, or cGMP, regulations and a limited number of manufacturers
comply with these requirements. If the other parties that we choose to manufacture our drug products are
not compliant with cGMP, the FDA may not approve our application to manufacture our drug products.
We may not be able to arrange for our drug candidates or any drug products that we may develop to be
manufactured by one of these parties on reasonable terms, if at all. Failure to comply with cGMP in the
manufacture of our products could result in the FDA withdrawing or denying regulatory approval of our
drug product or other enforcement actions.

We may not be able to obtain sufficient quantities of our drug candidates or any drug products we may
develop  if  our  designated  manufacturers  do  not  have  the  capacity  or  capability  to  manufacture  our
products  according  to  our  schedule  and  specifications.  Also,  raw  materials  that  may  be  required  to
manufacture any products we develop may only be available from a limited number of suppliers. If we have
promised delivery of a new product and are unable to meet the delivery requirement due to manufacturing
difficulties, our development programs would be delayed, and we may have to expend additional sums in

22

order to ensure that manufacturing capacity is available when we need it even if we do not use all of the
manufacturing capacity. This expense  would adversely affect our operating results.

Manufacturers  of  pharmaceutical  products  often  encounter  difficulties  in  production,  especially  in
scaling up initial production. These problems include difficulties with production costs and yields, quality
control  and  assurance  and  shortages  of  qualified  personnel,  as  well  as  compliance  with  strictly  enforced
federal,  state  and  foreign  regulations.  We  may  not  be  able  to  adequately  manage  and  oversee  the
manufacturers we choose, they may not perform as agreed or they may terminate their agreements with us.
Foreign  manufacturing  approval  processes  typically  include  all  of  the  risks  associated  with  the  FDA
approval process for manufacturing and  may  also include additional risks.

We may incur additional expense in order  to market our drug products.

We do not have experience marketing drug products. If the FDA grants regulatory approval to one or
more  of  our  drug  candidates,  we  would  have  to  employ  additional  personnel  or  engage  another  party  to
market our drug products, which would  be an  additional expense to us.

We might not be able to commercialize our drug candidates successfully, and we may spend significant time
and money attempting to do so.

We  have  a  limited  number  of  drug  candidates  in  early  stage  Phase  I  and  Phase  II  clinical  trials.  We
have  also  licensed  to  Pfizer  our  portfolio  of  CCR2  antagonist  compounds.  We,  or  our  collaborators  or
licensees,  may  decide  to  discontinue  development  of  any  or  all  of  our  drug  candidates  at  any  time  for
commercial,  scientific  or  other  reasons.  We  discontinued  development  of  DFC  in  April  2006  for  safety
reasons. If a product is developed, but is not marketed, we may have spent significant amounts of time and
money  on  it,  which  would  adversely  affect  our  operating  results  and  financial  condition.  Even  if  a  drug
candidate  that  we  develop  receives  regulatory  approval,  we  may  decide  not  to  commercialize  it  if  we
determine that commercialization of that product would require more money and time than we are willing
to  invest.  For  example,  drugs  that  receive  approval  are  subject  to  post-regulatory  surveillance  and  may
have  to  be  withdrawn  from  the  market  if  previously  unknown  side  effects  occur.  At  this  point,  the
regulatory agencies may require additional clinical trials or testing. Once a drug is marketed, if it causes
side  effects,  the  drug  product  may  be  recalled  or  may  be  subject  to  reformulation,  additional  studies,
changes  in  labeling,  warnings  to  the  public  and  negative  publicity.  As  a  result,  we  may  not  continue  to
commercialize a product even though it has obtained regulatory approval. Further, we may decide not to
continue to commercialize a product if the market does not accept the product because it is too expensive
and  third  parties  such  as  insurance  companies  or  Medicare  have  not  approved  it  for  substantial
reimbursement. In addition, we may decide not to continue to commercialize a product if another product
comes on the market that is as effective but has fewer side effects. There is also a risk that competitors may
develop similar or superior products or have proprietary rights that preclude us from ultimately marketing
our  products.

Our  ability  to  generate  revenues  will  be  diminished  if  we  are  unable  to  obtain  acceptable  prices  or  an
adequate level of reimbursement from payors of  healthcare  costs.

The continuing efforts of government and insurance companies, health maintenance organizations, or
HMOs, and other payors of healthcare costs to contain or reduce costs of health care may affect our future
revenues and profitability, and the future revenues and profitability of our potential customers, suppliers
and collaborative or license partners and the availability of capital. For example, in certain foreign markets,
pricing  or  profitability  of  prescription  pharmaceuticals  is  subject  to  government  control.  In  the  United
States,  given  recent  federal  and  state  government  initiatives  directed  at  lowering  the  total  cost  of  health
care, the U.S. Congress and state legislatures will likely continue to focus on health care reform, the cost of
prescription pharmaceuticals and on the reform of the Medicare and Medicaid systems. While we cannot
predict  whether  any  such  legislative  or  regulatory  proposals  will  be  adopted,  the  announcement  or

23

adoption of these proposals could reduce the price that we or any of our collaborators or licensees receive
for any products in the future.

Our  ability  to  commercialize  our  products  successfully  will  depend  in  part  on  the  extent  to  which
appropriate  reimbursement  levels  for  the  cost  of  our  products  and  related  treatment  are  obtained  by
governmental  authorities,  private  health  insurers  and  other  organizations,  such  as  HMOs.  Third-party
payors  are  increasingly  challenging  the  prices  charged  for  medical  products  and  services.  Also,  the  trend
toward  managed  health  care  in  the  United  States  and  the  concurrent  growth  of  organizations  such  as
HMOs, which could control or significantly influence the purchase of health care services and products, as
well as legislative proposals to reform health care or reduce government insurance programs, may all result
in lower prices for or rejection of our products. The cost containment measures that health care payors and
providers are instituting and the effect of any health care reform could materially and adversely affect our
ability to generate revenues.

As  our  drug  discovery  and  development  operations  are  conducted  at  our  headquarters  in  Wilmington,
Delaware, the loss of access to this facility would negatively  impact our business.

Our facility in Wilmington, Delaware is our headquarters and is also where we conduct all of our drug
discovery operations and research and development activities. Our lease contains provisions that provide
for  its  early  termination  upon  the  occurrence  of  certain  events  of  default  or  upon  a  change  of  control.
Further,  our  headquarters  facility  is  located  in  a  large  research  and  development  complex  that  may  be
temporarily  or  permanently  shutdown  if  certain  environmental  or  other  hazardous  conditions  were  to
occur within the complex. In addition, actions of activists opposed to aspects of pharmaceutical research
may disrupt our experiments or our ability to access or use our facilities. The loss of access to or use of our
Wilmington, Delaware, facility, either on a temporary or permanent basis, or early termination of our lease
would result in an interruption of our business and, consequently, would adversely affect the advancement
of our drug discovery and development  programs  and our overall  business.

We depend on key employees in a competitive market for skilled personnel, and the loss of the services of
any of our key employees or our inability to attract and retain additional personnel would affect our ability
to expand our drug discovery and development programs and achieve  our objectives.

We  are  highly  dependent  on  the  principal  members  of  our  management,  operations  and  scientific
staff. We experience intense competition for qualified personnel. Our future success also depends in part
on the continued service of our executive management team, key scientific and management personnel and
our ability to recruit, train and retain essential scientific personnel for our drug discovery and development
programs, including those who will be responsible for overseeing our preclinical testing and clinical trials as
well as for the establishment of collaborations with other companies. If we lose the services of any of these
people or if we are unable to recruit sufficient qualified personnel, our research and product development
goals,  including  the  identification  and  establishment  of  key  collaborations,  operations  and  marketing
efforts could be delayed or curtailed. We do not maintain ‘‘key person’’ insurance on any of our employees.

24

If we fail to manage our growth effectively, our ability to develop and commercialize products could suffer.

We  expect  that  if  our  clinical  drug  candidates  continue  to  progress  in  development,  we  continue  to
build our development organization and our drug discovery efforts continue to generate drug candidates,
we will require significant additional investment in personnel, management and resources. Our ability to
commercialize  our  drug  candidates  and  to  achieve  our  research  and  development  objectives  depends  on
our  ability  to  respond  effectively  to  these  demands  and  expand  our  internal  organization,  systems  and
controls to accommodate additional anticipated growth. If we are unable to manage our growth effectively,
our  business could be harmed and our  ability to execute our business strategy  could  suffer.

We may encounter difficulties in integrating companies we acquire, which may harm our operations and
financial results.

As  part  of  our  business  strategy,  we  have  in  the  past  and  may  in  the  future  acquire  assets,
technologies,  compounds  and  businesses.  Our  past  acquisitions,  such  as  the  acquisition  of  Maxia  have
involved, and our future acquisitions  may involve, risks such as the following:

(cid:127) we may be exposed to unknown liabilities of acquired companies;

(cid:127) our  acquisition  and  integration  costs  may  be  higher  than  we  anticipated  and  may  cause  our

quarterly and annual operating results  to  fluctuate;

(cid:127) we  may  experience  difficulty  and  expense  in  assimilating  the  operations  and  personnel  of  the
acquired businesses, disrupting our business  and  diverting our  management’s time and  attention;

(cid:127) we  may  be  unable  to  integrate  or  complete  the  development  and  application  of  acquired

technology, compounds or drug candidates;

(cid:127) we  may  experience  difficulties  in  establishing  and  maintaining  uniform  standards,  controls,

procedures and policies;

(cid:127) our  relationships  with  key  customers,  suppliers,  or  collaborative  or  license  partners  of  acquired
businesses  may  be  impaired,  due  to  changes  in  management  and  ownership  of  the  acquired
businesses;

(cid:127) we may be unable to retain key employees of the  acquired  businesses;

(cid:127) we may incur amortization or impairment expenses if an acquisition results in significant goodwill or

other intangible assets; or

(cid:127) our stockholders may be diluted if we pay for the acquisition with equity securities.

If product liability lawsuits are brought against us, we could face substantial liabilities and may be required
to limit commercialization of our products and our results  of operations could be harmed.

The  clinical  trials  and  marketing  of  medical  products  that  are  intended  for  human  use  entails  an
inherent risk of product liability. If any product that we or any of our collaborators or licensees develops
causes or is alleged to cause injury or is found to be unsuitable during clinical trials, manufacturing or sale,
we may be held liable. If we cannot successfully defend ourselves against product liability claims, we may
incur substantial liabilities, including substantial damages to be paid to the plaintiffs and legal costs, or we
may  be  required  to  limit  commercialization  of  our  products.  Our  product  liability  insurance  policy  that
provides coverage for liabilities arising from our clinical trials may not fully cover our potential liabilities.
In addition, we may determine that we should increase our coverage upon the undertaking of new clinical
trials, and this insurance may be prohibitively expensive to us or our collaborators or licensees and may not
fully  cover  our  potential  liabilities.  Our  inability  to  obtain  sufficient  product  liability  insurance  at  an
acceptable  cost  to  protect  against  potential  product  liability  claims  could  prevent  or  inhibit  the
commercialization of pharmaceutical products we develop, alone or with our collaborators. Additionally,

25

any  product  liability  lawsuit  could  cause  injury  to  our  reputation,  recall  of  products,  participants  to
withdraw from clinical trials, and potential collaborators or licensees to seek other partners, any of which
could impact our results of operations.

Because  our  activities  involve  the  use  of  hazardous  materials,  we  may  be  subject  to  claims  relating  to
improper handling, storage or disposal  of these  materials that  could be time consuming  and costly.

We  are  subject  to  various  environmental,  health  and  safety  laws  and  regulations  governing,  among
other things, the use, handling, storage and disposal of regulated substances and the health and safety of
our  employees.  Our  research  and  development  processes  involve  the  controlled  use  of  hazardous  and
radioactive  materials  and  biological  waste  resulting  in  the  production  of  hazardous  waste  products.  We
cannot  completely  eliminate  the  risk  of  accidental  contamination  or  discharge  and  any  resultant  injury
from these materials. If any injury or contamination results from our use or the use by our collaborators or
licensees of these materials, we may be sued and our liability may exceed our insurance coverage and our
total assets. Further, we may be required to indemnify our collaborators or licensees against all damages
and  other  liabilities  arising  out  of  our  development  activities  or  products  produced  in  connection  with
these  collaborations  or  licenses.  Compliance  with  the  applicable  environmental  and  workplace  laws  and
regulations is expensive. Future changes to environmental, health, workplace and safety laws could cause
us  to  incur  additional  expense  or  may  restrict  our  operations  or  impair  our  research,  development  and
production efforts.

RISKS RELATING TO OUR FINANCIAL RESULTS

We  expect to incur losses in the future and we  may not achieve  or maintain profitability in  the future.

We had net losses from inception in 1991 through 1996 and in 1999 through 2007. Because of those
losses, we had an accumulated deficit of $1.0 billion as of December 31, 2007. We will continue to spend
significant  amounts  on  our  efforts  to  discover  and  develop  drugs.  As  a  result,  we  expect  to  continue  to
incur losses in 2008 and in future periods as well.

We anticipate that our drug discovery and development efforts will increase as we focus on the studies,
including preclinical tests and clinical trials prior to seeking regulatory approval, that are required before
we can sell a drug product. The development of drug products will require us to spend significant funds on
research, development, testing, obtaining regulatory approvals, manufacturing and marketing. To date, we
do  not  have  any  drug  products  that  have  generated  revenues  and  we  cannot  assure  you  that  we  will
generate revenues from the drug candidates that we license or develop for several years, if ever. We cannot
be certain whether or when we will achieve profitability because of the significant uncertainties relating to
our  ability  to  generate  commercially  successful  drug  products.  Even  if  we  were  successful  in  obtaining
regulatory  approvals  for  manufacturing  and  commercializing  a  drug  candidate,  we  expect  that  we  will
continue  to  incur  losses  if  our  drug  products  do  not  generate  significant  revenues.  If  we  achieve
profitability, we may not be able to sustain or increase profitability.

We will need additional capital in the future. The capital markets may not permit us to raise additional
capital at the time that we require it, which could result in limitations on our research and development or
commercialization  efforts or the loss of certain of our  rights in our technologies or drug candidates.

Our future funding requirements will depend on many factors and we anticipate that we will need to
raise  additional  capital  to  fund  our  business  plan  and  research  and  development  efforts  going-forward.
Additional factors that may affect our future funding  requirements  include:

(cid:127) any changes in the breadth of our  research  and  development programs;

(cid:127) the results of research and development, preclinical testing and clinical trials conducted by us or our

future collaborative partners or licensees, if any;

26

(cid:127) the acquisition or licensing of businesses, technologies  or compounds, if any;

(cid:127) our ability to maintain and establish new corporate  relationships and research collaborations;

(cid:127) competing technological and market developments;

(cid:127) the amount of revenues generated from our  business activities, if any;

(cid:127) the  time  and  costs  involved  in  filing,  prosecuting,  defending  and  enforcing  patent  and  intellectual

property claims;

(cid:127) the receipt of contingent licensing or milestone fees or royalties on product sales from our current

or future collaborative and license arrangements,  if  established; and

(cid:127) the timing of regulatory approvals,  if  any.

If  we  require  additional  capital  at  a  time  when  investment  in  companies  such  as  ours,  or  in  the
marketplace  generally,  is  limited  due  to  the  then  prevailing  market  or  other  conditions,  we  may  have  to
scale back our operations, eliminate one or more of our research or development programs, or attempt to
obtain funds by entering into an agreement with a collaborative partner that would result in terms that are
not favorable to us or relinquishing our rights in certain of our proprietary technologies or drug candidates.
If we are unable to raise funds at the time that we desire or at any time thereafter on acceptable terms, we
may  not  be  able  to  continue  to  develop  our  potential  drug  products.  The  sale  of  equity  or  additional
convertible  debt  securities  in  the  future  would  be  dilutive  to  our  stockholders,  and  debt  financing
arrangements  may  require  us  to  pledge  certain  assets  or  enter  into  covenants  that  could  restrict  our
operations or our ability to incur further indebtedness.

Our current revenues are derived from collaborations and from licensing our intellectual property. If we are
unable to achieve milestones, develop products or renew or enter into new collaborations, our revenues may
decrease,  and  future  milestone  and  royalty  payments  from  our  gene  and  genomics-related  intellectual
property may not contribute significantly to revenues for several years, and may never result in revenues.

We  derived  substantially  all  of  our  revenues  for  the  year  ended  December  31,  2007  from  our
collaborative  research  and  license  agreement  with  Pfizer  and  from  licensing  our  intellectual  property  to
others. We may be unable to enter into additional collaborative agreements. Revenues from research and
development  collaborations  depend  upon  continuation  of  the  collaborations,  the  achievement  of
milestones and royalties we earn from any future products developed from our research. If we are unable
to successfully achieve milestones or our collaborators fail to develop successful products, we will not earn
the revenues contemplated under our collaborative agreements. Part of our prior strategy was to license to
our  database  customers  and  to  other  pharmaceutical  and  biotechnology  companies  our  know-how  and
patent  rights  associated  with  the  information  we  have  generated  in  the  creation  of  our  proprietary
databases,  for  use  in  the  discovery  and  development  of  potential  pharmaceutical,  diagnostic  or  other
products.  Any  potential  product  that  is  the  subject  of  such  a  license  will  require  several  years  of  further
development, clinical trials and regulatory approval before commercialization, all of which is beyond our
control,  and  possibly  beyond  the  control  of  our  licensee.  These  licensees  may  not  develop  the  potential
product  if  they  do  not  devote  the  necessary  resources  or  decide  that  they  do  not  want  to  expend  the
resources  to  do  the  clinical  trials  necessary  to  obtain  the  necessary  regulatory  approvals.  Therefore,
milestone or royalty payments from these licenses may not contribute to our revenues for several years, if
at  all.  We  have  decided  to  discontinue  some  of  our  gene  and  genomics-related  patent  prosecution  and
maintenance,  and  may  in  the  future  decide  to  discontinue  additional  gene  and  genomics-related  patent
prosecution  and  maintenance,  which  could  limit  our  ability  to  receive  license-based  revenues  from  our
gene and genomics-related patent portfolio.

We have a large amount of debt and our debt service obligations may prevent us from taking actions that we
would otherwise consider to be in our best interests.

As  of  December  31,  2007,  the  aggregate  principal  amount  of  total  consolidated  debt  was
$421.8  million  and  our  stockholders’  deficit  was  $159.5  million.  The  documents  pursuant  to  which  our
outstanding convertible senior and subordinated notes were issued do not limit the issuance of additional
indebtedness.  Our  substantial  leverage  could  have  significant  negative  consequences  for  our  future
operations, including:

(cid:127) increasing our vulnerability to general  adverse  economic  and industry conditions;

(cid:127) limiting  our  ability  to  obtain  additional  financing  for  working  capital,  capital  and  research  and

development expenditures, and general corporate purposes;

(cid:127) requiring the dedication of a substantial portion of our expected cash flow or our existing cash to
service  our  indebtedness,  thereby  reducing  the  amount  of  our  cash  available  for  other  purposes,
including working capital, capital expenditures and research and development expenditures;

(cid:127) limiting  our  flexibility  in  planning  for,  or  reacting  to,  changes  in  our  business  and  the  industry  in

which  we compete; or

(cid:127) placing  us  at  a  possible  competitive  disadvantage  compared  to  less  leveraged  competitors  and

competitors that have better access to capital resources.

In  the  past  five  years,  we  have  had  negative  cash  flow  from  operations.  We  likely  will  not  generate
sufficient cash flow from our operations in the future to enable us to meet our anticipated fixed charges,
including  our  debt  service  requirements  with  respect  to  our  outstanding  convertible  senior  notes  and
convertible  subordinated  notes.  As  of  December  31,  2007,  $151.8  million  aggregate  principal  amount  of
our 31⁄2% convertible senior notes due 2011 was outstanding. Our annual interest payments, beginning in
2007,  for  the  31⁄2%  convertible  senior  notes  through  2010,  assuming  none  of  these  notes  are  converted,
redeemed, repurchased or exchanged, are $5.3 million, and an additional $2.6 million in interest is payable
in  2011.  As  of  December  31,  2007,  $250.0  million  aggregate  principal  amount  of  our  31⁄2%  convertible
subordinated  notes  due  2011  was  outstanding.  Our  annual  interest  payments  for  the  31⁄2%  convertible
subordinated notes through 2010, assuming none of these notes are converted, redeemed, repurchased or
exchanged,  are  $8.8  million,  and  an  additional  $4.4  million  in  interest  is  payable  in  2011.  As  of
December  31,  2007,  $20.0  million  aggregate  principal  amount  of  the  non-interest  bearing  convertible
subordinated notes held by Pfizer was outstanding, of which $10.0 million is due in 2013 and $10.0 million
is  due  in  2014.  If  we  are  unable  to  generate  cash  from  our  operations  or  raise  additional  cash  through
financings  sufficient  to  meet  these  obligations,  we  will  need  to  use  existing  cash  or  liquidate  marketable
securities  in  order  to  fund  these  obligations,  which  may  delay  or  curtail  our  research,  development  and
commercialization programs.

RISKS RELATING TO INTELLECTUAL  PROPERTY AND LEGAL  MATTERS

If we are subject to arbitration, litigation and infringement claims, they could be costly and disrupt our
drug discovery and development efforts.

The  technology  that  we  use  to  make  and  develop  our  drug  products,  the  technology  that  we
incorporate in our products, and the products we are developing may be subject to claims that they infringe
the patents or proprietary rights of others. The success of our drug discovery and development efforts will
also  depend  on  our  ability  to  develop  new  compounds,  drugs  and  technologies  without  infringing  or
misappropriating the proprietary rights of others. We are aware of patents and patent applications filed in
certain countries claiming certain intellectual property relating to certain of our drug discovery targets such
as CCR5. While the validity of issued patents, patentability of pending patent applications and applicability
of any of them to our programs are uncertain, if any of these patents are asserted against us or if we choose

28

to license any of these patents, our ability to commercialize our products could be harmed or the potential
return  to us from any product that may  be successfully commercialized could  be  diminished.

From time to time we may receive notices from third parties offering licenses to technology or alleging
patent,  trademark,  or  copyright  infringement,  claims  regarding  trade  secrets  or  other  contract  claims.
Receipt  of  these  notices  could  result  in  significant  costs  as  a  result  of  the  diversion  of  the  attention  of
management  from  our  drug  discovery  and  development  efforts.  Parties  sending  these  notices  may  have
brought and in the future may bring  litigation against us  or seek arbitration relating  to  contract claims.

We may be involved in future lawsuits or other legal proceedings alleging patent infringement or other
intellectual property rights or contract violations. In addition, litigation or other legal proceedings may be
necessary to:

(cid:127) assert  claims of infringement;

(cid:127) enforce our patents or trademarks;

(cid:127) protect our trade secrets or know-how; or

(cid:127) determine the enforceability, scope  and  validity  of  the proprietary rights of others.

We  may  be  unsuccessful  in  defending  or  pursuing  these  lawsuits,  claims  or  other  legal  proceedings.
Regardless  of  the  outcome,  litigation  or  other  legal  proceedings  can  be  very  costly  and  can  divert
management’s efforts. For example, we recently settled patent litigation with Invitrogen Corporation. We
incurred  significant  expenses  related  to  this  litigation  and,  as  part  of  the  settlement,  paid  Invitrogen
$3.4  million.  An  adverse  determination  may  subject  us  to  significant  liabilities  or  require  us  or  our
collaborators  or  licensees  to  seek  licenses  to  other  parties’  patents  or  proprietary  rights.  We  or  our
collaborators  or  licensees  may  also  be  restricted  or  prevented  from  manufacturing  or  selling  a  drug  or
other product that we or they develop. Further, we or our future collaborators or licensees may not be able
to obtain any necessary licenses on acceptable terms, if at all. If we are unable to develop non-infringing
technology or license technology on a timely basis or on reasonable terms, our business could be harmed.

We may be unable to adequately protect or enforce our proprietary information, which may result in its
unauthorized use, a loss of revenue under a collaboration agreement or loss of sales to generic versions of
our products or otherwise reduce our ability to compete  in developing and commercializing products.

Our  business  and  competitive  position  depends  in  significant  part  upon  our  ability  to  protect  our
proprietary  technology,  including  any  drug  products  that  we  create.  Despite  our  efforts  to  protect  this
information,  unauthorized  parties  may  attempt  to  obtain  and  use  information  that  we  regard  as
proprietary. For example, one of our collaborators may disclose proprietary information pertaining to our
drug  discovery  efforts.  Our  patent  applications  may  fail  to  result  in  issued  patents.  In  addition,  because
patent applications can take several years to issue as patents, there may be pending patent applications of
others that may later issue as patents that cover some aspect of our drug candidates. Our existing patents
and  any  future  patents  we  may  obtain  may  not  be  broad  enough  to  protect  our  products  or  all  of  the
potential  uses  of  our  products,  or  otherwise  prevent  others  from  developing  competing  products  or
technologies. In addition, our patents may be challenged and invalidated or may fail to provide us with any
competitive advantages if, for example, others were first to invent or first to file a patent application for the
technologies and products covered by our  patents.

Additionally,  when  we  do  not  control  the  prosecution,  maintenance  and  enforcement  of  certain
important  intellectual  property,  such  as  a  drug  compound  in-licensed  to  us  or  subject  to  a  collaboration
with a third party, the protection of the intellectual property rights may not be in our hands. If we do not
control  the  intellectual  property  rights  in-licensed  to  us  with  respect  to  a  compound  and  the  entity  that
controls  the  intellectual  property  rights  does  not  adequately  protect  those  rights,  our  rights  may  be
impaired, which may impact our ability to develop, market and commercialize the in-licensed compound.

29

Our means of protecting our proprietary rights may not be adequate, and our competitors may:

(cid:127) independently develop substantially  equivalent proprietary information, products  and techniques;

(cid:127) otherwise gain access to our proprietary information; or

(cid:127) design around patents issued to us  or our other intellectual property.

We pursue a policy of having our employees, consultants and advisors execute proprietary information
and  invention  agreements  when  they  begin  working  for  us.  However,  these  agreements  may  not  provide
meaningful protection for our trade secrets or other proprietary information in the event of unauthorized
use or disclosure. If we fail to maintain trade secret and patent protection, our potential, future revenues
may be decreased.

If the effective term of our patents is decreased due to changes in the United States patent laws or if we need
to refile some of our patent applications, the value of our patent portfolio and the revenues we derive from it
may be decreased.

The  value  of  our  patents  depends  in  part  on  their  duration.  A  shorter  period  of  patent  protection
could lessen the value of our rights under any patents that we obtain and may decrease the revenues we
derive from our patents. The United States patent laws were amended in 1995 to change the term of patent
protection  from  17  years  from  patent  issuance  to  20  years  from  the  earliest  effective  filing  date  of  the
application. Because the time from filing to issuance of biotechnology applications may be more than three
years  depending  on  the  subject  matter,  a  20-year  patent  term  from  the  filing  date  may  result  in
substantially shorter patent protection. Also, we may need to refile some of our applications filed before
1995  that  claim  large  numbers  of  genes  or  other  additional  subject  matter  and,  in  these  situations,  the
patent  term  will  be  measured  from  the  date  of  the  earliest  priority  application.  This  would  shorten  our
period of patent exclusivity and may decrease the  revenues  that we might derive from  the patents.

International patent protection is particularly uncertain and costly, and if we are involved in opposition
proceedings in foreign countries, we  may  have  to expend substantial sums and management resources.

Biotechnology and pharmaceutical patent law outside the United States is even more uncertain and
costly than in the United States and is currently undergoing review and revision in many countries. Further,
the laws of some foreign countries may not protect our intellectual property rights to the same extent as
United  States  laws.  For  example,  certain  countries  do  not  grant  patent  claims  that  are  directed  to  the
treatment  of  humans.  We  may  participate  in  opposition  proceedings  to  determine  the  validity  of  our
foreign patents or our competitors’ foreign patents, which could result in substantial costs and diversion of
our  efforts. 

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties

Our  corporate  headquarters  is  in  Wilmington,  Delaware,  which  is  where  our  drug  discovery  and
development operations are also located. These facilities are leased to us until June 2010. We believe that
these facilities are adequate to meet our business requirements for the near-term and that additional space
will  be  available  on  commercially  reasonable  terms,  if  required.  In  addition  to  this  lease,  we  had  lease
agreements  as  of  December  31,  2007  for  facilities  that  were  closed  as  a  part  of  the  restructurings  of  our
genomic information business in Palo Alto and San Diego, California. As of December 31, 2007, we had
multiple sublease and lease agreements covering approximately 273,000 square feet that expire on various
dates  ranging  from  June  2008  to  March  2011.  Of  the  approximately  273,000  square  feet  leased,
approximately 174,000 square feet of this  space is currently  subleased  to  others.

Item  7. Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations

The  following  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  should  be
read  in  conjunction  with  ‘‘Selected  Consolidated  Financial  Data’’  and  the  Consolidated  Financial
Statements  and  related  Notes  included  elsewhere  in  this  Report.

Overview

Incyte  is  a  drug  discovery  and  development  company  focused  on  developing  proprietary  small
molecule  drugs  to  treat  serious  unmet  medical  needs.  We  have  a  pipeline  with  programs  in  oncology,
inflammation,  diabetes  and  human  immunodeficiency  virus  (HIV).

Thus  far  in  our  drug  discovery  and  development  activities,  which  began  in  early  2002,  we  have  filed
twelve  Investigational  New  Drug  Applications  (INDs)  and  have  progressed  eight  internally  developed
proprietary compounds into clinical development. Currently, four of these compounds have advanced into
Phase  II  clinical  trials.  Our  wholly-owned  pipeline  includes  the  following  compounds:

We  anticipate  incurring  additional  losses  for  several  years  as  we  expand  our  drug  discovery  and
development  programs.  We  also  expect  that  losses  will  fluctuate  from  quarter  to  quarter  and  that  such
fluctuations  may  be  substantial.  Conducting  clinical  trials  for  our  drug  candidates  in  development  is  a
lengthy, time-consuming and expensive process. We do not expect to generate product sales from our drug
discovery and development efforts for several years, if at all. If we are unable to successfully develop and
market pharmaceutical products over the next several years, our business, financial condition and results of
operations  would  be  adversely  impacted.

Collaborative Research and License Agreement with Pfizer

Effective in January 2006, we entered a collaborative research and license agreement with Pfizer Inc.
(‘‘Pfizer’’)  for  the  pursuit  of  our  CCR2  antagonist  program.  We  received  an  upfront  nonrefundable
payment of $40.0 million in January 2006. In addition, we received an aggregate of $20.0 million through
the  purchase  of  convertible  subordinated  notes,  $10.0  million  in  February  2006  and  $10.0  million  in
October  2007  (the  ‘‘Pfizer  Notes’’),  and  we  are  eligible  to  receive  additional  future  development  and
milestone  payments  of  up  to  $740.0  million  for  the  successful  development  and  commercialization  of
CCR2  antagonists  in  multiple  indications,  as  well  as  royalties  on  worldwide  sales.  We  received  a
$3.0  million  milestone  payment  from  Pfizer  in  2007.  Pfizer  gained  worldwide  development  and
commercialization rights to our portfolio of CCR2 antagonist compounds, the most advanced of which was
in  Phase  IIa  clinical  trials  in  rheumatoid  arthritis  and  insulin-resistant  obese  patients  at  the  time  the
agreement  became  effective  in  January  2006.  Pfizer’s  rights  extend  to  the  full  scope  of  potential
indications, with the exception of multiple sclerosis and lupus nephritis and other autoimmune nephritides,
for  which  we  retained  worldwide  rights,  along  with  certain  compounds.  We  do  not  have  obligations  to
Pfizer on preclinical development candidates we  select for pursuit  in these indications.

Restructuring Programs

In  February  2004,  we  made  the  decision  to  discontinue  further  development  of  our  information
products line, close our Palo Alto headquarters and focus solely on the discovery and development of novel
drugs. We recorded $42.1 million in restructuring charges in 2004, including charges related to the closure
of  our  facilities,  prior  tenant  improvements  and  equipment,  a  workforce  reduction  and  other  items.  The
restructuring  charge  originally  included  the  present  value  of  future  lease  obligations  for  two  facilities.  In
the fourth quarter of 2004, we made a lease termination payment to satisfy our remaining lease obligation
with  respect  to  one  of  the  facilities.  The  lease  obligation  for  the  second  facility  extends  through  March
2011. As a result of the long term nature of the remaining lease obligation, we will be recording a charge
each period through the March 2011 termination date of the lease related to increases in the fair value of
the lease obligations in accordance with the provisions of Financial Accounting Standards Board (‘‘FASB’’)
Statement  No.  146,  Accounting  for  Costs  Associated  with  Exit  or  Disposal  Activities,  which  total
approximately  $0.9  million  at  December  31,  2007.  The  cash  impact  in  2007  from  restructuring  related
charges was $5.6 million.

Critical Accounting Policies and Significant Estimates

The  preparation  of  financial  statements  requires  us  to  make  estimates,  assumptions  and  judgments
that  affect  the  reported  amounts  of  assets,  liabilities,  revenues  and  expenses,  and  related  disclosures  of
contingent assets and liabilities. On an on-going basis, we evaluate our estimates. We base our estimates on
historical  experience  and  various  other  assumptions  that  we  believe  to  be  reasonable  under  the
circumstances, the results of which form our basis for making judgments about the carrying values of assets
and  liabilities  that  are  not  readily  apparent  from  other  sources.  Actual  results  may  differ  from  those
estimates under different assumptions  or  conditions.

We  believe  the  following  critical  accounting  policies  affect  the  more  significant  judgments  and

estimates used in the preparation of our consolidated  financial  statements:

(cid:127) Revenue recognition;

(cid:127) Research and development costs;

(cid:127) Valuation of long-lived assets;

(cid:127) Restructuring charges; and

(cid:127) Stock compensation.

Revenue Recognition. Revenues are recognized when persuasive evidence of an arrangement exists,
delivery has occurred or services have been rendered, the price is fixed and determinable and collectibility
is reasonably assured.

36

We have entered into various types of agreements for access to our information databases and use of
our  intellectual  property.  Revenues  are  deferred  for  fees  received  before  earned  or  until  no  further
obligations  exist.  We  exercise  judgment  in  determining  that  collectibility  is  reasonably  assured  or  that
services  have  been  delivered  in  accordance  with  the  arrangement.  We  assess  whether  the  fee  is  fixed  or
determinable  based  on  the  payment  terms  associated  with  the  transaction  and  whether  the  sales  price  is
subject to refund or adjustment. We assess collectibility based primarily on the customer’s payment history
and on the creditworthiness of the customer.

Revenues from ongoing database agreements are recognized evenly over the access period. Revenues
from  licenses  to  our  intellectual  property  are  recognized  when  earned  under  the  terms  of  the  related
agreements. Royalty revenues are recognized upon the sale of products or services to third parties by the
licensee  or  other  agreed  upon  terms.  We  estimate  royalty  revenues  based  on  previous  period  royalties
received  and  information  provided  by  the  third  party  licensee.  We  exercise  judgment  in  determining
whether  the  information  provided  by  licensees  is  sufficiently  reliable  for  us  to  base  our  royalty  revenue
recognition thereon.

Under  agreements  involving  multiple  products,  services  and/or  rights  to  use  assets,  the  multiple
elements are divided into separate units of accounting when certain criteria are met, including whether the
delivered  items  have  stand  alone  value  to  the  customer  and  whether  there  is  objective  and  reliable
evidence of the fair value of the undelivered items. When separate units of accounting exist, consideration
is allocated among the separate elements based on their respective fair values. The determination of fair
value of each element is based on objective evidence from historical sales of the individual elements by us
to other customers. If such evidence of fair value for each undelivered element of the arrangement does
not exist, all revenue from the arrangement is deferred until such time that evidence of fair value for each
undelivered element does exist or until all elements of the arrangement are delivered. When elements are
specifically  tied  to  a  separate  earnings  process,  revenue  is  recognized  when  the  specific  performance
obligation  tied  to  the  element  is  completed.  When  revenues  for  an  element  are  not  specifically  tied  to  a
separate earnings process, they are recognized  ratably  over  the term  of the agreement.

In  connection  with  our  collaborative  research  and  license  agreement  with  Pfizer,  we  received  an
upfront  non-refundable  payment  of  $40.0  million  in  January  2006.  The  $40.0  million  upfront  fee  was
recorded as deferred revenue and is being recognized on a straight-line basis over two years, our estimated
performance period under the agreement. In February 2006 and October 2007, Pfizer purchased the Pfizer
Notes. As the Pfizer Notes are non-interest bearing, they have been discounted to their net present value.
The  difference  between  the  cash  received  and  the  present  value  of  the  Pfizer  Notes,  plus  the  related
beneficial conversion feature, totals $3.2 million for each note, which represents additional consideration
from Pfizer under the agreement. We have accounted for this additional consideration as deferred revenue
and will recognize it over our estimated performance period under the agreement. We recognize contract
revenues  in  connection  with  research  services  provided  to  Pfizer  as  earned.  We  received  a  $3.0  million
milestone payment from Pfizer in 2007 that is included in contract revenues. All milestone payments will
be recognized as revenue upon the achievement of the  associated milestone.

Research  and  Development  Costs.

In  accordance  with  Statement  of  Financial  Accounting  Standards
No. 2 (‘‘SFAS 2’’), Accounting for Research and Development Costs, it is our policy to expense research and
development  costs  as  incurred.  We  often  contract  with  clinical  research  organizations  (‘‘CROs’’)  to
facilitate, coordinate and perform agreed upon research and development of a new drug. To ensure that
research and development costs are expensed as incurred, we record monthly accruals for clinical trials and
preclinical testing costs based on the  work  performed under the contract.

These CRO contracts typically call for the payment of fees for services at the initiation of the contract
and/or upon the achievement of certain clinical trial milestones. In the event that we prepay CRO fees, we
record the prepayment as a prepaid asset and amortize the asset into research and development expense
over  the  period  of  time  the  contracted  research  and  development  services  are  performed  in  accordance

37

with EITF 07-3, Accounting for Nonrefundable Advance Payments for Goods or Services to Be Used in Future
Research  and  Development  Activities.  Most  professional  fees,  including  project  and  clinical  management,
data  management,  monitoring,  and  medical  writing  fees  are  incurred  throughout  the  contract  period.
These professional fees are expensed based on their percentage of completion at a  particular date.

Our CRO contracts generally include pass through fees. Pass through fees include, but are not limited
to, regulatory expenses, investigator fees, travel costs, and other miscellaneous costs including shipping and
printing fees. Because these fees are incurred at various times during the contract term and they are used
throughout  the  contract  term,  we  record  a  monthly  expense  allocation  to  recognize  the  fees  during  the
contract period. Fees incurred to set up  the clinical trial are  expensed during the setup  period.

Valuation of Long-Lived Assets. We assess the impairment of long-lived assets, which includes property
and equipment as well as intangible and other assets, whenever events or changes in circumstances indicate
that the carrying value may not be recoverable. Factors we consider important that could indicate the need
for an impairment review include the following:

(cid:127) Significant changes in the strategy  of  our overall  business;

(cid:127) Significant  underperformance  relative  to  expected  historical  or  projected  future  operating  results;

(cid:127) Significant changes in the manner  of use  of  the acquired assets;

(cid:127) Significant negative industry or economic trends;

(cid:127) Significant decline in our stock price  for a sustained period; and

(cid:127) Our market capitalization relative to net  book value.

When  we  determine  that  the  carrying  value  of  long-lived  assets  may  not  be  recoverable  based  upon
the  existence  of  one  or  more  of  the  above  indicators  of  impairment,  in  accordance  with  Financial
Accounting  Standards  Board  (‘‘FASB’’)  Statement  No.  144,  Accounting  for  the  Impairment  or  Disposal  of
Long  Lived  Assets  (‘‘SFAS  144’’),  we  perform  an  undiscounted  cash  flow  analysis  to  determine  if
impairment exists. If impairment exists, we measure the impairment based on the difference between the
asset’s carrying amount and its fair value.

Restructuring Charges. Costs associated with restructuring activities initiated after December 31, 2002,
are accounted for in accordance with FASB Statement No. 146, Accounting for Costs Associated with Exit or
Disposal  Activities  (‘‘SFAS  146’’).  Costs  associated  with  restructuring  activities  initiated  prior  to
December  31,  2002  have  been  recorded  in  accordance  with  Emerging  Issues  Task  Force  (‘‘EITF’’)  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) (‘‘EITF 94-3’’) and Staff Accounting Bulletin No. 100,
Restructuring  and  Impairment  Charges  (‘‘SAB  100’’).  Restructuring  costs  resulting  from  the  acquisition  of
Maxia  Pharmaceuticals,  Inc.  (‘‘Maxia’’)  have  been  recorded  in  accordance  with  EITF  Issue  No.  95-3,
Recognition  of  Liabilities  in  Connection  with  a  Purchase  Business  Combination  (‘‘EITF  95-3’’).  The
restructuring  charges  are  comprised  primarily  of  costs  to  exit  facilities,  reduce  our  workforce,  write-off
fixed assets, and pay for outside services incurred in the restructuring. The workforce reduction charge is
determined  based  on  the  estimated  severance  and  fringe  benefit  charge  for  identified  employees.  In
calculating  the  cost  to  exit  the  facilities,  we  estimate  for  each  location  the  amount  to  be  paid  in  lease
termination  payments,  the  future  lease  and  operating  costs  to  be  paid  until  the  lease  is  terminated,  the
amount, if any, of sublease receipts and real estate broker fees. This requires us to estimate the timing and
costs of each lease to be terminated, the amount of operating costs, and the timing and rate at which we
might be able to sublease the site. To form our estimates for these costs, we perform an assessment of the
affected  facilities  and  consider  the  current  market  conditions  for  each  site.  We  also  estimate  our  credit
adjusted  risk  free  interest  rate  in  order  to  discount  our  projected  lease  payments  in  accordance  with
SFAS 146. Estimates are also used in our calculation of the estimated realizable value on equipment that is
being held for sale. These estimates are formed based on recent history of sales of similar equipment and

38

market  conditions.  Our  assumptions  on  either  the  lease  termination  payments,  operating  costs  until
terminated, the offsetting sublease receipts and estimated realizable value of fixed assets held for sale may
turn out to be incorrect and our actual cost may be materially different from our estimates. Our estimates
of  future  liabilities  may  change,  requiring  us  to  record  additional  restructuring  charges  or  reduce  the
amount of liabilities recorded.

At  the  end  of  each  reporting  period,  we  evaluate  the  remaining  accrued  balances  to  ensure  their
adequacy, that no excess accruals are retained and the utilization of the provisions are for their intended
purposes in accordance with developed exit plans. We periodically evaluate current available information
and  adjust  our  restructuring  reserve  as  necessary.  We  also  make  adjustments  related  to  accrued
professional  fees  to  adjust  estimated  amounts  to  actual.  For  the  year  ended  December  31,  2007,  such
adjustments  were  made  for  the  2002  restructuring  program,  2004  restructuring  program,  and  the
acquisition of Maxia.

Stock  Compensation. Effective  January  1,  2006,  we  adopted  Statement  of  Financial  Accounting
Standards  No.  123  (revised  2004)  (‘‘SFAS  123R’’),  Share-Based  Payment,  which  revised  Statement  of
Financial Accounting Standards 123 (‘‘SFAS 123’’), Accounting for Stock-Based Compensation. SFAS 123R
requires all share-based payment transactions with employees, including grants of employee stock options,
to  be  recognized  as  compensation  expense  over  the  requisite  service  period  based  on  their  relative  fair
values. SFAS 123R requires significant judgment and the use of estimates, particularly surrounding Black-
Scholes  assumptions  such  as  stock  price  volatility  and  expected  option  lives,  as  well  as  expected  option
forfeiture rates, to value equity-based compensation. SFAS 123R requires the recognition of the fair value
of  stock  compensation  in  the  statement  of  operations.  Prior  to  the  adoption  of  SFAS  123R,  stock-based
compensation  expense  related  to  employee  stock  options  was  not  recognized  in  the  statement  of
operations.  Prior  to  January  1,  2006,  we  had  adopted  the  disclosure-only  provisions  under  SFAS  123.
Under  the  provisions  of  SFAS  123R,  we  recorded  $10.1  million  and  $8.9  million  of  stock  compensation
expense for the years ended December 31, 2007 and 2006,  respectively.

Results of Operations

Years Ended December 31, 2007 and 2006

We  recorded  net  losses  from  operations  for  the  years  ended  December  31,  2007  and  2006  of
$86.9  million  and  $74.2  million,  respectively.  On  a  basic  and  diluted  per  share  basis,  net  loss  from
operations was $1.03 and $0.89 for the years ended  December 31,  2007 and 2006, respectively.

Our contract revenues were $29.8 million and $24.2 million in 2007 and 2006, respectively. Contract
revenues  were  derived  from  recognition  of  revenue  associated  with  the  Pfizer  $40.0  million  upfront  fee,
recognition of revenue associated with the debt discount and beneficial conversion feature related to the
Pfizer  Notes,  and  research  services  provided  to  Pfizer.  In  addition,  we  received  a  $3.0  million  milestone
payment from Pfizer during 2007.

Our  license  and  royalty  revenues  were  $4.6  million  and  $3.4  million  in  2007  and  2006,  respectively.
License  and  royalty  revenues  were  derived  from  database  subscriptions  and  licensing  of  our  gene-  and

39

genomic-related  intellectual  property.  We  expect  that  revenues  generated  from  information  products,
including licensing of gene- and genomic-related intellectual property, will decline as we focus on our drug
discovery  and development programs.

For the year ended December 31, 2006, revenues from companies considered to be related parties, as
defined by FASB Statement No. 57, Related Party Disclosures (‘‘SFAS 57’’) was $0.3 million. There was no
such revenue recorded for the year ended December 31, 2007. Our related parties consist of companies in
which members of our Board of Directors have invested, either directly or indirectly, or in which a member
of our Board of Directors is an officer or holds a seat on the Board of Directors (other than an Incyte-held
Board seat).

We currently track research and development costs by natural expense line and not costs by project.
Salary and benefits related expense increased from 2006 to 2007 due to increased development headcount
and  incentive  compensation  expense.  Stock  compensation  expense  may  fluctuate  from  period  to  period
based  on  the  number  of  options  granted,  stock  price  volatility  and  expected  option  lives,  as  well  as
expected  option  forfeiture  rates  which  are  used  to  value  equity-based  compensation.  The  increase  in
collaboration  and  outside  services  from  2006  to  2007  is  due  primarily  from  the  growth  and  steady
advancement  of  our  clinical  pipeline.  The  increase  in  occupancy  and  other  costs  from  2006  to  2007  was
primarily the result of costs associated with intellectual property protection.

Research and development expenses may fluctuate from period to period depending upon the stage of
certain projects and the level of preclinical and clinical trial-related activities. Many factors can affect the
cost and timing of our clinical trials, including inconclusive results requiring additional clinical trials, slow
patient enrollment, the need to enroll additional patient cohorts, adverse side effects among patients, the
availability  of  supplies  for  our  clinical  trials  and  real  or  perceived  lack  of  effectiveness  or  safety  of  our
investigational drugs in our clinical trials. In addition, the development of all of our product candidates will
be subject to extensive governmental regulation. These factors make it difficult for us to predict the timing
and costs of the further development  and approval of our products.

Salary  and  benefits  related  expense  increased  from  2006  to  2007  due  to  increased  incentive
compensation  expense.  Stock  compensation  expense  may  fluctuate  from  period  to  period  based  on  the
number  of  options  granted,  stock  price  volatility  and  expected  option  lives,  as  well  as  expected  option
forfeiture rates which are used to value equity-based  compensation.

Other expenses. Other expenses for the years ended December 31, 2007 and 2006 were $(0.4) million
and  $2.9  million,  respectively.  The  decrease  from  2006  to  2007  is  due  primarily  to  the  settlement
agreement with Invitrogen related to our discontinued genomic information business which resulted in a
$3.4  million  charge  recorded  in  other  expenses  in  2006.  This  settlement  resolved  all  outstanding  claims
included in the litigation.

In 2007, we recorded $0.7 million of expense in connection with our 2004 restructuring program and
$0.9  million  of  benefit  in  connection  with  our  2002  restructuring  program  and  a  facility  closed  in
connection with our acquisition of Maxia. In 2006, we recorded $1.0 million of expense in connection with
our  2004  restructuring  program  and  $1.5  million  of  benefit  in  connection  with  our  2002  restructuring
program and a facility closed in connection with our acquisition of Maxia.

Interest  and  other  income  (expense),  net,  for  the  years

from  2006  was  primarily  attributable  to  the  $8.5  million  realized  gain  recorded  from  the  sale  of  our
investment in a privately-held company in December 2007 offset by a lower average cash balance during
2007. In 2006, we recorded a $6.2 million realized gain from the sale of our investment in a publicly-held
company  offset  by  an  impairment  charge  of  $1.3  million  recorded  to  reduce  the  carrying  value  of  our
investment in a privately-held investee.

Interest expense.

Interest expense for the years ended December 31, 2007 and 2006 was $24.0 million
and $17.9 million, respectively. The increase in 2007 from 2006 is primarily attributable to the increase in
accretion of the discount related to the 31⁄2% convertible senior notes due 2011 (the ‘‘31⁄2% Senior Notes’’)
issued in September 2006 of $8.2 million in 2007 compared to $2.1 million in the corresponding period of
2006.

Gain  (loss)  on  redemption/repurchase  of  convertible  subordinated  notes.

In  2006  we  redeemed
$91.6 million principal amount of our 5.5% convertible subordinated notes due 2007 (the ‘‘5.5% Notes’’).
The redemption resulted in a loss of $0.1 million for the year ended  December 31, 2006.

Provision  (benefit)  for  income  taxes. Due  to  our  net  losses  in  2007  and  2006,  we  did  not  have  an

annual income tax  provision.

Years Ended December 31, 2006 and 2005

We recorded net losses from continuing operations for the years ended December 31, 2006 and 2005
of  $74.2  million  and  $103.4  million,  respectively.  On  a  basic  and  diluted  per  share  basis,  net  loss  from
continuing operations was $0.89 and $1.24 for the years ended December 31, 2006 and 2005, respectively.

Our  contract  revenues  were  $24.2  million  and  $0.0  million  in  2006  and  2005,  respectively.  Contract
revenues  were  derived  from  recognition  of  revenue  associated  with  the  Pfizer  $40.0  million  upfront  fee,
recognition of revenue associated with the debt discount and beneficial conversion feature related to the
Pfizer Note due 2013, and research services provided  to  Pfizer.

Our  license  and  royalty  revenues  were  $3.4  million  and  $7.8  million  in  2006  and  2005,  respectively.
License  and  royalty  revenues  were  derived  from  database  subscriptions  and  licensing  of  our  gene-  and
genomic-related  intellectual  property.  The  decrease  in  license  and  royalty  revenues  from  2005  to  2006  is
attributable  to  our  decision  to  discontinue  offering  information  products.  The  increase  in  revenues  from
2005 to 2006 was due to our collaborative  research  and  license agreement  with Pfizer.

For the year ended December 31, 2006 revenues from companies considered to be related parties, as
defined  by  SFAS  57  were  $0.3  million.  There  were  no  such  revenues  recorded  for  the  year  ended
December 31, 2005.

We currently track research and development costs by natural expense line and not costs by project.
Stock  compensation  costs  for  the  year  ended  December  31,  2006  was  the  result  of  our  adoption  of
SFAS 123R which required the recognition of stock compensation expense in our consolidated statement
of operations. Stock compensation expense may fluctuate from period to period based on the number of
options granted, stock price volatility and expected option lives, as well as expected option forfeiture rates
which  are  used  to  value  equity-based  compensation.  The  decrease  in  collaboration  and  outside  services
from 2005 to 2006 is due primarily the result of decreased drug discovery and development costs due to our
collaborative research and license agreement with Pfizer and the decision in April 2006 to discontinue the

42

development  of  our  DFC  program.  The  decrease  in  occupancy  and  other  costs  from  2005  to  2006  was
primarily the result of increased efficiency in  our  use of laboratory and reagent supplies.

Stock  compensation  costs  for  the  year  ended  December  31,  2006  was  the  result  of  our  adoption  of
SFAS 123R which required the recognition of stock compensation expense in our consolidated statement
of operations. Stock compensation expense may fluctuate from period to period based on the number of
options granted, stock price volatility and expected option lives, as well as expected option forfeiture rates
which  are used to value equity-based compensation.

Other expenses. Other expenses for the years ended December 31, 2006 and 2005 were $2.9 million
and  $1.4  million,  respectively,  and  represent  charges  recorded  in  connection  with  restructuring  and
long-lived asset impairments. The increase from 2005 to 2006 is due primarily to the settlement agreement
with Invitrogen related to our discontinued genomic information business which resulted in a $3.4 million
charge  recorded  in  other  expenses.  This  settlement  resolved  all  outstanding  claims  included  in  the
litigation.

In 2006, we recorded $1.0 million of expense in connection with our 2004 restructuring program and
$1.5  million  of  benefit  in  connection  with  our  2002  restructuring  program  and  a  facility  closed  in
connection with our acquisition of Maxia.

In  2005,  in  conjunction  with  our  2004  restructuring  program,  we  recorded  $1.0  million  in  expense,
including  charges  related  to  the  closure  of  our  Palo  Alto  facility,  previously  capitalized  tenant
improvements  and  equipment,  a  workforce  reduction  and  other  items.  During  2005,  we  also  recorded
charges of $0.4 million of expense in connection with our 2002 restructuring program and a facility closed
in connection with our acquisition of  Maxia.

Other  income (expense)

Interest  and  other  income  (expense),  net.

Interest  and  other  income  (expense),  net,  for  the  years
ended December 31, 2006 and 2005 was $20.7 million and $12.5 million, respectively. The increase in 2006
from  2005  was  primarily  attributable  to  the  $6.2  million  realized  gain  recorded  from  the  sale  of  our
investment in a publicly-held company in March 2006 and due to higher interest rates in 2006 offset by an
impairment charge of $1.3 million recorded in June 2006 to reduce the carrying value of our investment in
a privately-held investee. In 2005 we realized a $2.8 million gain from the sale of securities of a strategic
investee.

Interest expense.

Interest expense for the years ended December 31, 2006 and 2005 was $17.9 million
and $16.1 million, respectively. The increase in 2006 from 2005 is primarily attributable to the accretion of
$2.1 million of the discount related to the 31⁄2% Senior Notes issued in September 2006.

Losses  on  certain  derivative  financial  instruments. Losses  on  certain  derivative  financial  instruments
for  the  year  ended  December  31,  2005  of  $0.1  million  represents  the  change  in  fair  value  of  certain
long-term investments, specifically warrants held in other companies, in accordance with FASB Statement

43

No. 133, Accounting for Derivative Financial Instruments and Hedging Activities (‘‘SFAS 133’’). Gain or loss
on derivative financial instruments may fluctuate in any given period based upon current market conditions
and is recognized during the period of  change.

Gain  (loss)  on  repurchase  of  convertible  subordinated  notes.

In  2006  we  redeemed  $91.6  million
principal amount and in 2005 we repurchased, on the open market, $36.5 million face value of our 5.5%
Notes.  The  redemption  and  repurchase  resulted  in  a  gain  (loss)  of  $(0.1)  million  and  $0.5  million,
respectively, for the years ended December  31, 2006 and 2005.

Provision  (benefit)  for  income  taxes. Due  to  our  net  losses  in  2006  and  2005,  we  had  a  minimal
effective annual income tax rate. The benefit for income taxes for 2005 is primarily attributable to foreign
withholding taxes.

Gain  (loss)  from  discontinued  operation. The  gain  from  discontinued  operation  of  $0.3  million  in
2005 represent the results of our Proteome facility based in Beverly, Massachusetts. In December 2004, we
entered  into  an  agreement  to  sell  certain  assets  and  liabilities  related  to  our  Proteome  facility,  which
subsequently closed in January 2005. The consolidated financial statements have been restated to present
the operations of our Proteome facility  as a discontinued operation for all periods presented.

Recent  Accounting Pronouncements

In July 2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes,
an  interpretation  of  FASB  Statement  No.  109  (‘‘FIN  48’’).  FIN  48  prescribes  a  recognition  threshold  and
measurement attribute for the financial statement recognition and measurement of a tax position taken or
expected to be taken in a tax return. We adopted FIN 48 on January 1, 2007. The adoption of FIN 48 did
not have a material impact on our condensed consolidated financial statements.

Sources and Uses of Cash. Due to our significant research and development expenditures, we have
not been profitable and have generated operating losses since we were incorporated in 1991 through 1996
and  in  1999  through  2007.  As  such,  we  have  funded  our  research  and  development  operations  through
sales  of  equity  securities,  the  issuance  of  convertible  subordinated  notes,  cash  received  from  customers,
and  collaborative  arrangements.  As  of  December  31,  2007,  approximately  $0.9  million  of  marketable
securities were classified as long-term assets on the condensed consolidated balance sheet as they had been
in  an  unrealized  loss  position  for  longer  than  six  months  and  we  had  the  ability  to  hold  them  until  the
carrying value recovers, which may be longer than one year. At December 31, 2007, we had available cash,
cash  equivalents,  and  short-term  and  long-term  marketable  securities  of  $257.3  million.  Our  cash  and
marketable securities balances are held in a variety of interest-bearing instruments including obligations of
U.S. government agencies, high-grade corporate bonds, asset backed and mortgage backed securities and

44

money  market  accounts.  Available  cash  is  invested  in  accordance  with  our  investment  policy’s  primary
objectives of liquidity, safety of principal  and  diversity of investments.

Cash used in Operating Activities. The $42.3 million increase in cash used in operating activities from
2006  to  2007  was  due  primarily  to  the  $40.0  million  nonrefundable  upfront  fee  received  from  Pfizer  in
January 2006. The $51.5 million decrease in cash used in operating activities from 2005 to 2006 was also
due primarily to the $40.0 million upfront fee received from Pfizer in  January 2006.

Cash  provided  by  Investing  Activities. Our  investing  activities,  other  than  purchases,  sales  and
maturities  of  marketable  securities,  have  consisted  predominantly  of  capital  expenditures  and  sales  and
purchases  of  long-term  investments.  In  the  future,  net  cash  used  by  investing  activities  may  fluctuate
significantly from period to period due to the timing of strategic equity investments, acquisitions, including
possible  earn-out  payments  to  former  Maxia  stockholders,  capital  expenditures  and  maturities/sales  and
purchases of marketable securities.

Cash  provided  by  (used  in)  Financing  Activities.

In  connection  with  the  collaborative  research  and
license agreement, Pfizer purchased a $10.0 million Pfizer Note in October 2007. In addition, we received
$2.3  million  of  proceeds  from  issuance  of  common  stock  under  our  stock  plans  and  employee  stock
purchase  plan.  During  2006,  we  issued  a  total  of  $151.8  million  of  31⁄2%  Senior  Notes,  which  resulted  in
cash proceeds of approximately $111.9 million. In addition, we redeemed $91.6 million of the 5.5% Notes
during  2006.  In  connection  with  the  collaborative  research  and  license  agreement,  Pfizer  purchased  a
$10.0  million  Pfizer  Note  in  February  2006.  During  2005,  we  paid  $35.8  million  in  connection  with
repurchases  of  $36.5  million  in  face  value  of  the  5.5%  Notes,  offset  partially  by  $1.5  million  of  proceeds
from issuance of common stock under  our  stock plans  and employee stock purchase plan.

The  following  summarizes  our  significant  contractual  obligations  as  of  December  31,  2007  and  the
effect those obligations are expected to have on our liquidity and cash flow in future periods (in millions):

The amounts and timing of payments related to vacated facilities may vary based on negotiated timing
of  lease  terminations.  We  have  entered  into  sublease  agreements  for  our  vacated  space  with  scheduled
payments to us of $3.1 million (less than 1 year), $4.2 million (years 1 - 3), and $0.3 million (years 4 - 5);
these scheduled payments are not reflected in the above table.

The  table  above  excludes  certain  commitments  that  are  contingent  upon  future  events.  The  most
significant of these contractual commitments that we consider to be contingent obligations are summarized
below.

Commitments related to our acquisition of Maxia are considered contingent commitments as future
events must occur to cause these commitments to be enforceable. We completed our acquisition of Maxia
in  February  2003.  Under  the  merger  agreement,  former  Maxia  stockholders  have  the  right  to  receive
certain earn out amounts of up to a potential aggregate amount of $14.0 million upon the occurrence of

45

certain research and development milestones set forth in the merger agreement. Twenty percent of each
earn out payment, if earned, will be paid in cash and the remaining eighty percent will be paid in shares of
our common stock such that an aggregate of $2.8 million in cash and $11.2 million in our common stock
(based  upon  the  then  fair  value)  could  potentially  be  paid  pursuant  to  the  earn  out  milestones.  The
milestones  are  set  to  occur  as  Maxia  products  enter  various  stages  of  human  clinical  trials  and  may  be
earned  at  any  time  prior  to  the  tenth  anniversary  of  the  consummation  of  the  merger.  In  any  event,  no
more  than  13,531,138  shares  of  our  common  stock  may  be  issued  to  former  Maxia  stockholders  in  the
aggregate  pursuant  to  the  merger  agreement.  None  of  these  milestones  has  been  achieved  as  of
December 31, 2007.

We have entered into and may in the future seek to license additional rights relating to compounds or
technologies in connection with our drug discovery and development programs. Under these licenses, we
may be required to pay up-front fees, milestone payments, and royalties on sales  of future products.

We  believe  that  our  cash,  cash  equivalents  and  marketable  securities  will  be  adequate  to  satisfy  our
capital  needs  for  at  least  the  next  twelve  months.  Our  cash  requirements  depend  on  numerous  factors,
including  our  expenditures  in  connection  with  alliances,  license  agreements  and  acquisitions  of  and
investments  in  complementary  products,  technologies  and  businesses;  expenditures  in  connection  with
potential repayments of our 31⁄2% Senior Notes, 31⁄2% Subordinated Notes, the Pfizer Notes; expenditures
in  connection  with  our  drug  discovery  and  development  programs;  expenditures  in  connection  with
litigation or other legal proceedings; competing technological and market developments; the cost of filing,
prosecuting,  defending  and  enforcing  patent  claims  and  other  intellectual  property  rights;  our  receipt  of
any  milestone  or  other  payments  under  any  collaborative  agreements  we  may  enter  into,  including  the
agreement with Pfizer; and costs associated with the integration of new operations assumed through any
mergers and acquisitions. Changes in our research and development plans or other changes affecting our
operating  expenses  may  result  in  changes  in  the  timing  and  amount  of  expenditures  of  our  capital
resources.  We  expect  that  future  revenues  generated  from  information  products,  including  licensing  of
intellectual  property,  will  continue  to  decline  as  we  focus  on  drug  discovery  and  development  programs,
and in 2008, will not represent a significant source of cash inflow for us.

Off Balance Sheet Arrangements

We  have  no  material  off-balance  sheet  arrangements  other  than  those  that  are  discussed  under

Contractual Obligations.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Our  investments  in  marketable  securities,  which  are  composed  primarily  of  investment-grade
corporate bonds, U.S. government agency debt securities, mortgage and asset-backed securities and money
market  funds,  are  subject  to  default,  changes  in  credit  rating  and  changes  in  market  value.  These
investments  are  also  subject  to  interest  rate  risk  and  will  decrease  in  value  if  market  rate  interest  rates
increase.  As  of  December  31,  2007,  cash,  cash  equivalents  and  short-term  and  long-term  marketable
securities  were  $257.3  million.  Due  to  the  nature  of  these  investments,  if  market  interest  rates  were  to
increase immediately and uniformly by 10% from levels as of December 31, 2007 the decline in fair value
would not be material.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of  Incyte Corporation

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Incyte  Corporation  as  of
December 31, 2007 and 2006, and the related consolidated statements of operations, comprehensive loss,
stockholders’ equity (deficit) and cash flows for each of the three years in the period ended December 31,
2007.  Our  audits  also  included  the  financial  statement  schedule  listed  in  the  Index  at  item  15  (a).  These
financial statements and schedule are the responsibility of the Company’s management. Our responsibility
is to express an opinion on these financial  statements  and schedule based on our audits.

We  conducted  our  audits  in  accordance  with  the  standards  of  the  Public  Company  Accounting
Oversight  Board  (United  States).  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain
reasonable assurance about whether the financial statements are free of material misstatement. An audit
includes  examining,  on  a  test  basis,  evidence  supporting  the  amounts  and  disclosures  in  the  financial
statements. An audit also includes assessing the accounting principles used and significant estimates made
by  management,  as  well  as  evaluating  the  overall  financial  statement  presentation.  We  believe  that  our
audits provide a reasonable basis for our  opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the
consolidated  financial  position  of  Incyte  Corporation,  at  December  31,  2007  and  2006,  and  the
consolidated  results  of  its  operations  and  its  cash  flows  for  each  of  the  three  years  in  the  period  ended
December 31, 2007, in conformity with U.S. generally accepted accounting principles. Also, in our opinion,
the  related  financial  statement  schedule,  when  considered  in  relation  to  the  basic  financial  statements
taken as a whole, presents fairly in all material  respects the information set forth  therein.

As  discussed  in  Note  1  to  the  consolidated  financial  statements,  Incyte  Corporation  changed  its
method of accounting for stock-based compensation in accordance with Statement of Financial Accounting
Standards No. 123 (revised 2004) on January  1, 2006.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight
Board (United States), Incyte Corporation’s internal control over financial reporting as of December 31,
2007, based on criteria established in Internal Control—Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission and our report dated February 26, 2008 expressed
an unqualified opinion thereon.

INCYTE CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Organization and Summary of Significant Accounting Policies

Organization  and  Business.

Incyte  Corporation  (‘‘Incyte,’’  ‘‘we,’’  ‘‘us,’’  or  ‘‘our’’)  is  a  drug  discovery
and development company focused on developing proprietary small molecule drugs to treat serious unmet
medical  needs.  We  have  a  pipeline  with  programs  in  oncology,  inflammation,  diabetes,  and  human
immunodeficiency  virus (HIV).

We were founded and incorporated in Delaware in 1991. Until 2001, we devoted substantially all of
our  resources  to  the  development,  marketing  and  sales  of  information  and  genomic  products.  We  began
our  drug discovery and development activities in early 2002.

Principles  of  Consolidation. The  consolidated  financial  statements  include  the  accounts  of  Incyte
Corporation  and  our  wholly  owned  subsidiaries.  All  material  inter-company  accounts,  transactions,  and
profits have been eliminated in consolidation.

Reclassifications. Certain  amounts  reported  in  previous  years  have  been  reclassified  to  conform  to

the 2007 financial statement presentation.

Use  of  Estimates. The  preparation  of  financial  statements  in  conformity  with  accounting  principles
generally  accepted  in  the  United  States  requires  management  to  make  estimates  and  assumptions  that
affect  the  amounts  reported  in  the  financial  statements  and  accompanying  notes.  Actual  results  could
differ  from those estimates.

Foreign Currency Translation. The financial statements of subsidiaries outside the United States are
measured using the local currency as the functional currency. Assets and liabilities of these subsidiaries are
translated  at  the  rates  of  exchange  at  the  balance  sheet  date,  as  appropriate.  The  resulting  translation
adjustments  are  included  in  accumulated  other  comprehensive  income  (loss),  a  separate  component  of
stockholders’equity  (deficit).  Income  and  expense  items  are  translated  at  average  monthly  rates  of
exchange.

Concentrations  of  Credit  Risk. Cash,  cash  equivalents,  marketable  securities,  trade  receivables,  and
long-term strategic investments are financial instruments which potentially subject us to concentrations of
credit  risk.  The  estimated  fair  value  of  financial  instruments  approximates  the  carrying  value  based  on
available market information. We primarily invest our excess available funds in notes and bills issued by the
U.S. government and its agencies and corporate debt securities and, by policy, limit the amount of credit
exposure to any one issuer and to any one type of investment, other than securities issued or guaranteed by
the  U.S.  government.  Our  customers  for  our  information  products  are  primarily  pharmaceutical  and
biotechnology  companies  which  are  typically  located  in  the  United  States  and  Europe.  We  have  not
experienced  any  significant  credit  losses  on  cash,  cash  equivalents,  marketable  securities  or  trade
receivables to date and do not require collateral on  receivables.

Cash  and  Cash  Equivalents. Cash  and  cash  equivalents  are  held  in  U.S.  banks  or  in  custodial
accounts  with  U.S.,  and  U.K.  banks.  Cash  equivalents  are  defined  as  all  liquid  investments  and  money
market funds with maturity from date of purchase of 90 days or less that are readily convertible into cash
and have insignificant interest rate risk.

Marketable 

Securities—Available-for-Sale. All  marketable 

as
available-for-sale.  Available-for-sale  securities  are  carried  at  fair  value,  based  on  quoted  market  prices,
with  unrealized  gains  and  losses,  net  of  tax,  reported  as  a  separate  component  of  stockholders’  equity
(deficit).  We  classify  marketable  securities  available  to  fund  current  operations  as  current  assets  on  the
consolidated  balance  sheets.  Marketable  securities  are  classified  as  long-term  assets  on  the  consolidated

securities

balance sheets if (i) they have been in an unrealized loss position for longer than six months and (ii) we
have the ability to hold them until the carrying value is recovered and such holding period may be longer
than  one  year.  The  amortized  cost  of  debt  securities  in  this  category  is  adjusted  for  amortization  of
premiums  and  accretions  of  discounts  to  maturity.  Such  amortization  is  included  in  interest  income.
Realized  gains  and  losses  and  declines  in  value  judged  to  be  other  than  temporary  for  available-for-sale
securities are included in ‘‘Interest and other income (expense), net.’’ The cost of securities sold is based
on the specific identification method.

Accounts Receivable. As of December 31, 2007 and 2006 we had no allowance for doubtful accounts.
We  provide  an  allowance  for  doubtful  accounts  based  on  experience  and  specifically  identified  risks.
Accounts receivable are carried at fair value and charged off against the allowance for doubtful accounts
when we determine that recovery is unlikely  and  we  cease collection  efforts.

Property and Equipment. Property and equipment is stated at cost, less accumulated depreciation and
amortization. Depreciation is recorded using the straight-line method over the estimated useful lives of the
respective assets (generally three to five years). Leasehold improvements are amortized over the shorter of
the estimated useful life of the assets  or  lease term.

Certain laboratory and computer equipment used by us could be subject to technological obsolescence
in  the  event  that  significant  advancement  is  made  in  competing  or  developing  equipment  technologies.
Management  continually  reviews  the  estimated  useful  lives  of  technologically  sensitive  equipment  and
believes that those estimates appropriately reflect the current useful life of our assets. In the event that a
currently unknown significantly advanced technology became commercially available, we would re-evaluate
the  value  and  estimated  useful  lives  of  our  existing  equipment,  possibly  having  a  material  impact  on  the
financial statements.

Valuation of Long-Lived Assets. Long-lived assets, including certain identifiable intangible assets, to
be held and used are reviewed for impairment whenever events or changes in circumstances indicate that
the  carrying  amount  of  such  assets  may  not  be  recoverable  such  as  a  significant  industry  downturn  or  a
significant  decline  in  our  market  value.  Determination  of  recoverability  is  based  on  an  estimate  of
undiscounted cash flows resulting from the use of the asset and its eventual disposition. Measurement of
impairment charges for long-lived assets and certain identifiable intangible assets that management expects
to  hold  and  use  are  based  on  the  fair  value  of  such  assets.  Long-lived  assets  and  certain  identifiable
intangible assets to be disposed of are reported at the lower of carrying amount or fair value less costs to
sell. There have been no impairments of long-lived assets during the years ended December 31, 2007, 2006
or 2005.

Long-Term Investments. We have made equity and debt investments in a number of companies whose
businesses  may  be  complementary  to  our  business.  Most  of  these  investments  were  made  in  connection
with  the  establishment  of  a  collaborative  arrangement  between  us  and  the  investee  company.  Our
long-term  investments  have  historically  consisted  of  investments  in  both  privately  and  publicly-held
companies  in  which  we  have  owned  less  than  20%  of  the  outstanding  voting  stock  and  have  not  had  the
ability  to  exert  significant  influence  over  the  investees.  Accordingly,  our  long-term  investments  in
privately-held  companies  have  been  accounted  for  under  the  cost  method  and  our  investments  in
publicly-held  companies  have  been  accounted  for  in  accordance  with  Financial  Accounting  Standards
Board (‘‘FASB’’) Statement No. 115, Accounting for Certain Investments in Debt and Equity Securities. Our
investments  in  publicly-held  companies  are  classified  as  available-for-sale  and  are  adjusted  to  their  fair

55

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

Note 1. Organization and Summary of Significant  Accounting Policies (Continued)

value each period based on their quoted market price with any adjustments being recorded in accumulated
other comprehensive income (loss) as a separate component of stockholders’  equity (deficit).

We periodically evaluate the carrying value of our ownership interests in privately-held cost method
investees  by  reviewing  conditions  that  might  indicate  an  other-than  temporary  decline  in  fair  value,
including the following:

(cid:127) Financial performance of the investee;

(cid:127) Achievement  of  business  plan  objectives  and  milestones  including  the  hiring  of  key  employees,
obtaining key business partnerships, and  progress related  to research and development activities;

(cid:127) Available cash; and

(cid:127) Completion of debt and equity financings.

If our review of these factors indicates that an other-than-temporary decline in the fair value of the
investee  has  occurred,  we  estimate  the  fair  value  of  the  investee.  When  the  carrying  value  of  our
investments  is  materially  greater  than  our  pro-rata  share  of  the  estimated  fair  value  of  the  investee,  we
record an impairment charge to reduce our carrying value. Impairment charges are recorded in the period
when  the  related  triggering  condition  becomes  known  to  management.  We  use  the  best  information
available in performing our periodic evaluations; however, the information available may be limited. These
evaluations  involve  significant  management  judgment,  and  the  actual  amounts  realized  for  a  specific
investment  may  differ  from  the  carrying  value.  For  our  available-for-sale  investments  in  publicly-held
investees,  we  monitor  all  unrealized  losses  to  determine  whether  a  decline  in  fair  value  below  carrying
value  is  other-than-temporary.  Generally,  when  fair  value  is  materially  less  than  carrying  value  for  six
consecutive months, we consider the decline to be other-than-temporary. When we conclude that a decline
is  other-than-temporary,  we  adjust  the  carrying  value  of  our  long-term  investments  in  publicly-held
investees so that our carrying value per share is equal to the quoted market price per share. Future adverse
changes in market conditions or poor operating results of underlying investments could result in additional
impairment charges.

Derivative  Financial  Instruments. We  hold  warrants  to  purchase  equity  securities  of  a  publicly-held
company.  Warrants  that  can  be  exercised  and  settled  by  delivery  of  net  shares  such  that  we  pay  no  cash
upon exercise or that are held in public companies are deemed derivative financial instruments. Gains and
losses resulting from changes in fair value are recognized on the consolidated statements of operations in
‘‘Gain  (loss)  on  certain  derivative  financial  instruments’’  in  the  period  of  change.  We  determine  the  fair
value of our warrants through option pricing models using current market price and volatility assumptions.

Intangible  and  Other  Assets. Patent  application  costs  relating  to  ongoing  drug  discovery  and
development are charged to expense as incurred. In prior years, costs of patents, patent applications and
patent defense for gene and genomic patents were capitalized and amortized on a straight-line basis over
their  estimated  useful  lives  of  approximately  five  years  in  accordance  with  the  provisions  of  Accounting
Principles Board Opinion No. 17,  Intangible Assets (‘‘APB 17’’).

Income  Taxes.

Income  taxes  are  accounted  for  using  SFAS  No.  109,  Accounting  for  Income  Taxes.
Deferred income taxes are provided at the currently enacted income tax rates for the difference between
the financial statement and income tax basis of assets and liabilities and carry-forward items. The effective
tax rate and the tax basis of assets and liabilities reflect management’s estimates of the ultimate outcome of
various  tax  audits  and  issues.  In  addition,  valuation  allowances  are  established  for  deferred  tax  assets

56

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

where the amount of expected future taxable income from operations does not support the realization of
the asset. We believe that the current assumptions and other considerations used to estimate the current
year  effective  and  deferred  tax  positions  are  appropriate.  However,  if  the  actual  outcome  of  future  tax
consequences differs from our estimates and assumptions, the resulting change to the provision for income
taxes could have a material impact on our consolidated  financial  statements.

In July 2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes,
an  interpretation  of  FASB  Statement  No.  109  (‘‘FIN  48’’).  FIN  48  prescribes  a  recognition  threshold  and
measurement attribute for the financial statement recognition and measurement of a tax position taken or
expected to be taken in a tax return. We adopted FIN 48 on January 1, 2007. The adoption of FIN 48 did
not have a material impact on our condensed consolidated financial statements.

Financing  Costs  Related  to  Long-term  Debt. Costs  associated  with  obtaining  long-term  debt  are

deferred and amortized over the term  of the  related debt using the effective interest method.

Net Income (Loss) Per Share. We follow the provisions of SFAS No. 128, Earnings Per Share, which
requires  us  to  present  basic  and  diluted  earnings  per  share.  Our  basic  and  diluted  losses  per  share  are
calculated by dividing the net loss by the weighted average number of shares of common stock outstanding
during  all  periods  presented.  Options  to  purchase  stock  and  convertible  debt  are  included  in  diluted
earnings per share calculations, unless  the  effects are anti-dilutive.

Accumulated Other Comprehensive Income (Loss). Accumulated other comprehensive income (loss)

consists of the following:

Unrealized losses on marketable securities . . . . . . . . . . . . . . . . . . . .
Cumulative translation adjustment . . . . . . . . . . . . . . . . . . . . . . . . . .

Revenue Recognition. Revenues are recognized when persuasive evidence of an arrangement exists,
delivery has occurred or services have been rendered, the price is fixed and determinable and collectibility
is  reasonably  assured.  We  have  entered  into  various  types  of  agreements  for  access  to  our  information
databases and use of our intellectual property. Revenues are deferred for fees received before earned or
until  no  further  obligations  exist.  We  exercise  judgment  in  determining  that  collectibility  is  reasonably
assured or that services have been delivered in accordance with the arrangement. We assess whether the
fee is fixed or determinable based on the payment terms associated with the transaction and whether the
sales  price  is  subject  to  refund  or  adjustment.  We  assess  collectibility  based  primarily  on  the  customer’s
payment history and on the creditworthiness of the customer.

Revenues from ongoing database agreements are recognized evenly over the access period. Revenues
from  licenses  to  our  intellectual  property  are  recognized  when  earned  under  the  terms  of  the  related
agreements. Royalty revenues are recognized upon the sale of products or services to third parties by the
licensee  or  other  agreed  upon  terms.  We  estimate  royalty  revenues  based  on  previous  period  royalties
received  and  information  provided  by  the  third  party  licensee.  We  exercise  judgment  in  determining
whether  the  information  provided  by  licensees  is  sufficiently  reliable  for  us  to  base  our  royalty  revenue
recognition thereon.

INCYTE CORPORATION

Note 1. Organization and Summary of Significant  Accounting Policies (Continued)

Under  agreements  involving  multiple  products,  services  and/or  rights  to  use  assets,  the  multiple
elements are divided into separate units of accounting when certain criteria are met, including whether the
delivered  items  have  stand  alone  value  to  the  customer  and  whether  there  is  objective  and  reliable
evidence of the fair value of the undelivered items. When separate units of accounting exist, consideration
is allocated among the separate elements based on their respective fair values. The determination of fair
value of each element is based on objective evidence from historical sales of the individual elements by us
to other customers. If such evidence of fair value for each undelivered element of the arrangement does
not exist, all revenue from the arrangement is deferred until such time that evidence of fair value for each
undelivered element does exist or until all elements of the arrangement are delivered. When elements are
specifically  tied  to  a  separate  earnings  process,  revenue  is  recognized  when  the  specific  performance
obligation  tied  to  the  element  is  completed.  When  revenues  for  an  element  are  not  specifically  tied  to  a
separate earnings process, they are recognized  ratably over the term  of the agreement.

In  connection  with  our  collaborative  research  and  license  agreement  with  Pfizer  Inc.  (‘‘Pfizer’’),  we
received an upfront non-refundable payment of $40.0 million in January 2006. The $40.0 million upfront
fee was recorded as deferred revenue and is being recognized on a straight-line basis over two years, our
estimated  performance  period  under  the  agreement.  Pfizer  purchased  a  $10.0  million  principal  amount
convertible  subordinated  note  in  February  2006  and  an  additional  $10.0  million  principal  amount
convertible subordinated note (the ‘‘Pfizer Notes’’) in October 2007. As the Pfizer Notes are non-interest
bearing,  they  have  been  discounted  to  their  net  present  value.  The  difference  between  the  cash  received
and the present value of the Pfizer Notes, plus the related beneficial conversion feature, totals $3.2 million
for  each  note,  which  represents  additional  consideration  from  Pfizer  under  the  agreement.  We  have
accounted  for  this  additional  consideration  as  deferred  revenue  and  will  recognize  it  over  our  estimated
performance  period  under  the  agreement.  We  recognize  contract  revenues  in  connection  with  research
services provided to Pfizer as earned. We received a $3.0 million milestone payment from Pfizer in 2007
that  is  included  in  contract  revenues.  All  milestone  payments  will  be  recognized  as  revenue  upon  the
achievement of the associated milestone.

Research  and  Development. Research  and  development  expenses  are  comprised  of  the  following
types  of  costs  incurred  in  performing  research  and  development  activities:  salaries  and  related  benefits,
collaboration  and  outside  services,  and  occupancy  and  all  other  costs.  In  accordance  with  Statement  of
Financial Accounting Standards No. 2 (‘‘FAS 2’’), Accounting for Research and Development Costs, it is our
policy  to  expense  research  and  development  costs  as  incurred.  We  often  contract  with  Clinical  Research
Organizations (‘‘CROs’’) to facilitate, coordinate and perform agreed upon research and development of a
new  drug.  To  ensure  that  research  and  development  costs  are  expensed  as  incurred,  we  record  monthly
accruals for clinical trial and preclinical testing  costs based on the work performed under  the contract.

These  CRO  contracts  typically  call  for  payment  of  fees  for  services  at  the  initiation  of  the  contract
and/or upon the achievement of certain clinical trial milestones. In the event that we prepay CRO fees for
future milestones, we record the prepayment as a prepaid asset and amortize the asset into research and
development  expense  over  the  period  of  time  the  contracted  research  and  development  services  are
performed  in  accordance  with  EITF  07-3,  Accounting  for  Nonrefundable  Advance  Payments  for  Goods  or
Services to Be Used in Future Research and Development Activities. Most professional fees, including project
and clinical management, data management, monitoring, and medical writing fees are incurred throughout
the  contract  period.  These  professional  fees  are  expensed  based  on  their  percentage  of  completion  at  a
particular date.

58

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

INCYTE CORPORATION

Note 1. Organization and Summary of Significant  Accounting Policies (Continued)

Our CRO contracts generally include pass through fees. Pass through fees include, but are not limited
to, regulatory expenses, investigator fees, travel costs, and other miscellaneous costs including shipping and
printing fees. Because these fees are incurred at various times during the contract term and they are used
throughout  the  contract  term,  we  record  a  monthly  expense  allocation  to  recognize  the  fees  during  the
contract period. Fees incurred to set up  the clinical trial are expensed during the setup  period.

Other Expenses. We recognize other expenses in connection with our plans to exit certain activities.
In  connection  with  our  exit  activities,  we  record  other  expenses  for  employee  termination  benefit  costs,
long-lived  asset  impairments,  costs  related  to  leased  facilities  to  be  abandoned  or  subleased,  and  other
exit-related  costs.  These  charges  were  incurred  pursuant  to  formal  plans  developed  by  management  and
accounted  for  in  accordance  with  FASB  Statement  No.  146,  Accounting  for  Costs  Associated  with  Exit  or
Disposal  Activities,  (‘‘SFAS  146’’),  EITF  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)
(‘‘EITF 94-3’’) and EITF Issue No. 95-3, Recognition of Liabilities in Connection with a Purchase Business
Combination (‘‘EITF 95-3’’). Fixed assets that are written off or impaired as a result of restructuring plans
are typically held for sale or scrapped. The remaining carrying value of such assets was not material as of
December  31,  2007  and  2006.  The  recognition  of  other  expenses  requires  our  management  to  make
judgments  and  estimates  regarding  the  nature,  timing,  and  amount  of  costs  associated  with  the  planned
exit activity, including estimating sublease income and the fair value, less sales costs, of equipment to be
disposed  of.  Management’s  estimates  of  future  liabilities  may  change,  requiring  us  to  record  additional
restructuring  charges  or  reduce  the  amount  of  liabilities  already  recorded.  At  the  end  of  each  reporting
period,  we  evaluate  the  remaining  accrued  balances  to  ensure  that  they  are  adequate,  that  no  excess
accruals  are  retained,  and  that  the  utilization  of  the  provisions  are  for  their  intended  purposes  in
accordance with developed exit plans.

Stock-Based  Compensation. Effective  January  1,  2006,  we  adopted  Statement  of  Financial
Accounting  Standards  No.  123  (revised  2004)  (‘‘SFAS  123R’’),  Share-Based  Payment,  which  revised
Statement  of  Financial  Accounting  Standards  123  (‘‘SFAS  123’’),  Accounting 
for  Stock-Based
Compensation. SFAS 123R requires all share-based payment transactions with employees, including grants
of  employee  stock  options,  to  be  recognized  as  compensation  expense  over  the  requisite  service  period
based on their relative fair values. The application of SFAS 123R requires significant judgment and the use
of estimates, particularly surrounding Black-Scholes assumptions such as stock price volatility and expected
option lives, as well as expected option forfeiture rates, to value equity-based compensation. Prior to the
adoption  of  SFAS  123R,  stock-based  compensation  expense  related  to  employee  stock  options  was  not
recognized  in  the  statement  of  operations.  Prior  to  January  1,  2006,  we  had  adopted  the  disclosure-only
provisions  under  SFAS  123.  Under  the  provisions  of  SFAS  123R,  we  recorded  $10.1  million  and
$8.9 million, respectively, of stock compensation expense on our consolidated statements of operations for
the years ended December 31, 2007 and 2006. For the year ended December 31, 2005 we recorded stock
compensation  expense  of  $0.2  million  in  the  consolidated  statements  of  operations  related  to  restricted
shares issued to our Chief Executive Officer.

As  of  December  31,  2007,  approximately  $0.9  million  of  marketable  securities  were  classified  as
long-term  assets  on  the  consolidated  balance  sheets  as  they  have  been  in  an  unrealized  loss  position  for
longer than six months and we have the ability to hold them until the carrying value recovers, which may be
longer than one year.

Net  realized  gains  (loss)  of  ($0.4)  million,  $6.1  million  and  $1.3  million  from  sales  of  marketable
securities were included in ‘‘Interest and other income/(expense), net’’ in 2007, 2006 and 2005, respectively.

Note 3. Concentrations of Credit Risk

As  of  December  31,  2007,  we  previously  had  entered  into  agreements  for  information  products  and
services, which include licensing a portion of our intellectual property, with pharmaceutical, biotechnology
and agricultural companies and academic institutions. Such agreements represented 100% of license and
royalty  revenues  in  2007,  2006  and  2005.  In  general,  customers  agree  to  pay,  during  the  term  of  the
agreement,  fees  to  receive  non-exclusive  access  to  selected  modules  of  our  databases  and/or  licenses  of
certain  of  our  intellectual  property.  In  addition,  if  a  customer  develops  certain  products  utilizing  our
technology  or  proprietary  information,  we  could  potentially  receive  royalty  and  milestone  payments.  In
November 2005, we entered into a collaborative research and license agreement with Pfizer, which became
effective in January 2006.

A single customer contributed 87%, 88% and 21% of total revenues for the years ended December 31,

2007, 2006 and 2005, respectively.

Three customers comprised 68% and 78% of the accounts receivable balance as of December 31, 2007

and 2006, respectively.

Note 4. Collaborative License Agreement

Effective in January 2006, we entered a collaborative research and license agreement with Pfizer for
the pursuit of our CCR2 antagonist program. Pfizer gained worldwide development and commercialization
rights to our portfolio of CCR2 antagonist compounds. Pfizer’s rights extend to the full scope of potential
indications,  with  the  exception  of  multiple  sclerosis  and  autoimmune  nephritides,  where  we  retained
worldwide  rights,  along  with  certain  compounds.  We  do  not  have  obligations  to  Pfizer  on  pre-clinical
development candidates we select for pursuit in these indications.

INCYTE CORPORATION

Note 4. Collaborative License Agreement (Continued)

We received an upfront nonrefundable payment of $40.0 million in January 2006 and are eligible to
receive additional future development and milestone payments of up to $740.0 million for the successful
development  and  commercialization  of  CCR2  antagonists  in  multiple  indications,  as  well  as  royalties  on
worldwide  sales.  We  received  a  $3.0  million  milestone  payment  from  Pfizer  in  2007.  The  $40.0  million
upfront  fee  was  recorded  as  deferred  revenue  and  is  being  recognized  on  a  straight-line  basis  over  two
years,  our  estimated  performance  period  under  the  agreement.  Contract  revenues  related  thereto  of
approximately  $20.7  million  and  $20.3  million,  respectively,  were  recognized  for  the  years  ended
December 31, 2007 and 2006. All milestone payments will be recognized as revenue upon the achievement
of the associated milestone.

We also recognized contract revenues of approximately $1.5 million and $2.4 million, respectively, for
the years ended December 31, 2007 and 2006 in connection with research services provided to Pfizer. We
recognize  contract  revenues  in  connection  with  research  services  provided  to  Pfizer  as  earned.  At
December 31, 2007 approximately $0.4 million was receivable from Pfizer for reimbursement of expenses
incurred by us pursuant to the agreement.

Note 6. Long-Term Investments

In December 2007, we recorded a gain of approximately $8.5 million in interest and other income, net
as a result of the sale of Velocity11, a privately-held life sciences technology company in which we held an
ownership position. We may receive additional consideration of approximately $0.9 million after a one year
escrow period.

In June 2006, we recorded an impairment charge of $1.3 million in interest and other income, net to
reduce the carrying value of our investment in a privately-held investee because the investee had less than
six  months  of  cash  and  we  believed  that  the  likelihood  of  obtaining  future  debt  or  equity  financing  that
would not result in an impairment was  remote.

Note 6. Long-Term Investments (Continued)

In March 2006, we sold a portion of our investment in a publicly-held company accounted for under
FASB  Statement  No.  115,  Accounting  for  Certain  Investments  in  Debt  and  Equity  Securities,  for
$11.5 million, and in October 2006, we sold the remaining portion of this investment for $5.8 million, which
resulted in a aggregate realized gain of $6.2 million in interest and other income, net for the year ended
December 31, 2006.

In May 2005, we sold our investment in a publicly-held company accounted for under FASB Statement
No.  115,  Accounting  for  Certain  Investments  in  Debt  and  Equity  Securities,  for  $5.7  million,  resulting  in  a
realized gain of $2.8 million in interest  and other income, net.

The activity in our long-term investments, in any given period, may result in gains or losses on sales or
impairment charges. Amounts realized upon disposition of these investments may be different from their
carrying  value.

assets was $1.9 million, $2.3 million and  $2.7 million,  respectively.

In March 2002, in connection with his employment by Incyte as Executive Vice President and Chief
Drug  Discovery  Scientist,  Brian  W.  Metcalf  received  an  interest-free  loan  from  us  in  the  amount  of
$400,000 to be used for financing his residence in California. The loan was evidenced by a promissory note
and secured by the residence. On February 6, 2003, 25% of the outstanding principal balance was forgiven,
and 1⁄48 of the principal amount was forgiven on the last day of each month thereafter, with the remaining
outstanding  principal  balance  of  the  loan  forgiven  on  February  6,  2006.  We  amortized  this  loan  to
compensation expense on a straight-line basis over the  forgiveness period.

In  2004,  we  sublet  one  of  our  existing  facilities  to  a  third  party.  Under  the  terms  of  the  consent
agreement with the facility’s landlord, we were required to obtain a letter of credit in favor of the landlord
in  the  amount  of  $2.6  million.  The  deposit  and  the  related  amount  required  under  the  letter  of  credit
declines  monthly  on  a  pro-rata  basis  through  March  2011,  the  remaining  term  of  the  lease  agreement
assigned. The deposit is included in other  assets at  December  31, 2007.

In September 2006, we received proceeds of $111.9 million from the sale of $151.8 million aggregate
principal  amount  of  the  31⁄2%  convertible  senior  notes  due  2011  (the  ‘‘31⁄2%  Senior  Notes’’).  The  31⁄2%
Senior  Notes  bear  interest  at  the  rate  of  3.5%  per  year,  payable  semi-annually  on  February  15  and
August  15,  and  are  due  February  15,  2011.  The  31⁄2%  Senior  Notes  are  convertible  into  shares  of  our
common  stock  at  an  initial  conversion  rate  of  89.1385  shares  per  $1,000  principal  amount  of  the  31⁄2%
Senior Notes, equivalent to an initial conversion price of approximately $11.22 per share. The 31⁄2% Senior
Notes are senior in right of payment to our outstanding 31⁄2% convertible subordinated notes due 2011 (the
‘‘31⁄2% Subordinated Notes’’) and the Pfizer Notes due 2013 and 2014. We may redeem the 31⁄2% Senior
Notes  beginning  on  February  20,  2007.  The  31⁄2%  Senior  Notes  were  issued  at  a  discount  to  par  of

64

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

INCYTE CORPORATION

Note 8. Convertible Notes (Continued)

approximately  $39.9  million.  The  carrying  value  of  the  31⁄2%  Senior  Notes  is  $122.2  million  at
December 31, 2007. The 31⁄2% Senior Notes will accrete up to their face value over the 53 month term of
the notes by recording interest expense under the  effective interest method.

In connection with the collaborative research and license agreement, Pfizer purchased a $10.0 million
principal  amount  Pfizer  Note  in  February  2006  and  an  additional  $10.0  million  principal  amount  Pfizer
Note in October 2007. The Pfizer Notes bear no interest, are due seven years from the date of issuance and
are  convertible  into  our  common  stock  at  initial  conversion  prices  of  $6.8423  and  $9.75  per  share,
respectively,  subject  to  adjustments.  The  Pfizer  Notes  are  subordinated  to  all  senior  indebtedness,
including the 31⁄2% Senior Notes, and pari passu in right of payment with our 31⁄2% Subordinated Notes.
We  may,  at  our  option,  repay  the  Pfizer  Notes  beginning  February  3,  2009  and  October  10,  2010,
respectively. Pfizer may require us to repay the Pfizer Notes upon a change of control, as defined. As the
Pfizer Notes are non interest bearing, they have been discounted to their net present value of $6.8 million
each by imputing interest at a rate of 4.5% and 3.9%, respectively, which represented market conditions in
place  at  the  time  the  notes  were  issued.  The  carrying  value  of  the  Pfizer  Notes  were  $7.5  million  and
$6.8  million,  respectively,  at  December  31,  2007.  We  will  accrete  the  Pfizer  Notes  up  to  their  face  value
over  their  term  of  seven  years  by  recording  interest  expense  under  the  effective  interest  method.  The
difference between the cash received and the present value of the Pfizer Notes plus the related beneficial
conversion feature totals $3.2 million for each note, which represents additional consideration from Pfizer
under  the  agreement.  We  have  accounted  for  this  additional  consideration  as  deferred  revenue  and  will
recognize  it  over  our  estimated  performance  period  under  the  agreement.  Contract  revenues  related
thereto of approximately $4.7 million and $1.5 million, respectively, were recognized for the years ended
December 31, 2007 and 2006.

In February and March 2004, in a private placement, we issued a total of $250.0 million of the 31⁄2%
Subordinated  Notes,  which  resulted  in  net  proceeds  of  approximately  $242.5  million.  The  notes  bear
interest at the rate of 3.5% per year, payable semi-annually on February 15 and August 15. The notes are
subordinated  to  all  senior  indebtedness,  including  the  31⁄2%  Senior  Notes,  and  pari  passu  in  right  of
payment  with  the  Pfizer  Notes.  The  notes  are  convertible  into  shares  of  our  common  stock  at  an  initial
conversion  price  of  approximately  $11.22  per  share,  subject  to  adjustments.  Holders  may  require  us  to
repurchase  the  notes  upon  a  change  in  control,  as  defined.  We  may  redeem  the  notes  beginning
February 20, 2007.

Note 9. Other Expenses

The  estimates  below  have  been  made  based  upon  management’s  best  estimate  of  the  amounts  and
timing of certain events included in the restructuring plan that will occur in the future. It is possible that
the  actual  outcome  of  certain  events  may  differ  from  the  estimates.  Changes  will  be  made  to  the
restructuring accrual at the point that the differences become determinable. The accrual balances for the
restructuring  plans  are  included  in  accrued  restructuring  and  other  liabilities  (long-term)  in  the
consolidated balance sheets.

In  February  2004,  we  announced  a  restructuring  plan  to  close  our  information  products  research
facility and headquarters in Palo Alto, California and move our headquarters to our Wilmington, Delaware
pharmaceutical research and development facility. The closure of the Palo Alto facility corresponded with
terminating  further  development  activities  around  our  Palo  Alto-based  information  products  line.  The
restructuring plan included the elimination of 183 employees and charges related to the closure of our Palo
Alto  facilities,  previously  capitalized  tenant  improvements  and  equipment  and  other  items.  The  lease
commitment  and  related  costs  originally  included  the  present  value  of  future  lease  obligations  for  two
facilities.  In  the  fourth  quarter  of  2004,  we  made  a  lease  termination  payment  to  satisfy  our  remaining
lease  obligation  with  respect  to  one  of  the  facilities.  The  lease  obligation  for  the  second  facility  extends
through  March  2011.  As  a  result  of  the  long  term  nature  of  the  remaining  lease  obligation,  we  will  be
recording a charge each period through the March 2011 termination date of the lease related to increases
in  the  fair  value  of  the  lease  obligations  in  accordance  with  the  provisions  of  FASB  Statement  No.  146,
Accounting  for  Costs  Associated  with  Exit  or  Disposal  Activities,  which  total  approximately  $0.9  million  at

In  November  2002,  we  announced  plans  to  reduce  our  expenditures,  primarily  in  research  and
development,  through  a  combination  of  spending  reductions,  workforce  reductions,  and  office
consolidations.  The  plan  included  elimination  of  approximately  37%  of  our  approximately  700-person
workforce from our offices in Palo Alto, California; Beverly, Massachusetts; and Cambridge, England and
the consolidation of our office and research facilities in Palo Alto, California. As a result, we recorded an
expense of $33.9 million related to restructuring  activities in  the fourth  quarter  of  2002.

$(0.3)  million,  $(1.5)  million  and  $0.1  million,  respectively,  primarily  relating  to  this  facility  for  lease
expenses  in  excess  or  less  than  of  amounts  originally  estimated.  We  estimated  the  costs  based  on  the
contractual terms of agreements and current real estate market conditions. We may incur additional costs
associated with these subleasing and  lease  termination activities.

In accordance with EITF 95-3, we recorded a $2.9 million charge in 2003 related to restructuring costs
for Maxia Pharmaceuticals, Inc. (‘‘Maxia’’), which consisted of workforce reductions and consolidation of
facilities.  We  recorded  employee  termination  costs  of  approximately  $0.8  million  for  28  employee
positions. The job eliminations were completed in July 2003. We also recorded restructuring costs related
to  lease  payments  for  property  that  has  been  vacated  and  other  costs  of  $2.0  million.  In  2007,  2006  and
2005 we recorded additional charges of $(0.6) million, $(0.1) million and $0.3 million, respectively, relating
to  facilities  lease  expenses  in  excess  of  amounts  originally  estimated.  The  operating  lease  related  to  the
vacated facility expires in November  2008.

Note 10. Stockholders’ Deficit

Preferred  Stock. We  are  authorized  to  issue  5,000,000  shares  of  preferred  stock,  none  of  which  was
outstanding  as  of  December  31,  2007  or  2006.  The  Board  of  Directors  may  determine  the  rights,
preferences and privileges of any preferred stock issued in the future. We have reserved 250,000 shares of
preferred  stock  designated  as  Series  A  Participating  Preferred  Stock  for  issuance  in  connection  with  the
Stockholders Rights plan described below.

Common  Stock. As  of  December  31,  2007,  we  had  reserved  a  total  of  17,300,458  shares  of  our

common stock for future issuance related to our stock plans as described below.

On  November  5,  2004,  we  completed  a  public  offering  of  9  million  shares  of  our  authorized  but
unissued common stock at $9.75 per share pursuant to an effective shelf registration statement, resulting in
net  proceeds  of  $83.3  million  after  deducting  the  underwriting  discounts,  commissions  and  offering
expenses.

Stock  Compensation  Plans. Summaries  of  stock  option  activity  for  our  stock  option  plans  as  of
December 31, 2007, 2006 and 2005, and related information for the years ended December 31 are included
in the plan descriptions below.

1991 Stock Plan.

In November 1991, the Board of Directors adopted the 1991 Stock Plan (the ‘‘Stock
Plan’’),  which  was  amended  and  restated  for  issuance  of  common  stock  to  employees,  consultants,  and
scientific advisors. Options issued under the plan shall, at the discretion of the compensation committee of

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

Note 10. Stockholders’ Deficit (Continued)

the  Board  of  Directors,  be  either  incentive  stock  options,  nonstatutory  stock  options  or  restricted  stock
units. The exercise prices of incentive and non-statutory stock options granted under the plan are not less
than  the  fair  market  value  on  the  date  of  the  grant,  as  determined  by  the  Board  of  Directors.  Options
granted  after  February  2007  generally  vest  over  three  years,  pursuant  to  a  formula  determined  by  our
Board  of  Directors,  and  expire  after  seven  years.  Options  granted  prior  to  February  2007  generally  vest
over four years, pursuant to a formula determined by our Board of Directors, and expire after ten years.
Certain options granted in 2002 vest pro rata monthly over three years and expire after ten years. In May
2007,  our  stockholders  approved  an  increase  in  the  number  of  shares  of  common  stock  reserved  for
issuance under the Stock Plan from 22,350,000 to 25,350,000.

During 2001, we granted 490,000 restricted stock units under the Stock Plan to certain management
personnel. Stock compensation expense of $0.2 million was recorded in 2005. As of December 31, 2005, all
of the restricted stock units had vested or had been previously forfeited.

Non-Employee  Directors’  Stock  Option  Plan.

In  August  1993,  the  Board  of  Directors  approved  the
1993 Directors’ Stock Option Plan (the ‘‘Directors’ Plan’’), which was later amended. The Directors’ Plan
provides  for  the  automatic  grant  of  options  to  purchase  shares  of  common  stock  to  our  non-employee
directors. In June 2005, our stockholders approved an increase in the number of shares of common stock
reserved for issuance under the plan  from  1,100,000 to 1,500,000.

Under the Directors’ Plan, each new non-employee director joining the Board will receive an option
to  purchase  35,000  shares  of  common  stock.  Additionally,  members  who  continue  to  serve  on  the  Board
will receive annual option grants for 20,000 shares exercisable in full on the first anniversary of the date of
the grant. All options are exercisable  at the fair market value of the  stock on the  date of grant.

Employee Stock Purchase Plan. On May 21, 1997, our stockholders adopted the ESPP. In May 2006,
our stockholders approved an increase in the number of shares available for grant from 3,100,000 shares to
3,850,000  shares.  Each  regular  full-time  and  part-time  employee  working  20  hours  or  more  per  week  is
eligible  to  participate  after  one  month  of  employment.  We  issued  337,689,  313,715  and  389,801  shares
under the ESPP in 2007, 2006 and 2005, respectively. For the year ended December 31, 2007 and 2006 we
recorded stock compensation expense of $0.4 million and $0.4 million, respectively, under SFAS 123R as
the ESPP is considered compensatory under SFAS 123R. As of December 31, 2007, 638,484 shares remain
available for issuance under the ESPP.

Stockholders  Rights  Plan. On  September  25,  1998,  the  Board  of  Directors  adopted  a  Stockholder
Rights  Plan  (the  ‘‘Rights  Plan’’),  pursuant  to  which  one  preferred  stock  purchase  right  (a  ‘‘Right’’)  was
distributed  for  each  outstanding  share  of  common  stock  held  of  record  on  October  13,  1998.  One  Right
will also attach to each share of common stock issued by the Company subsequent to such date and prior
to  the  distribution  date  defined  below.  Each  Right  represents  a  right  to  purchase,  under  certain
circumstances,  a  fractional  share  of  our  Series  A  Participating  Preferred  Stock  at  an  exercise  price  of
$100.00,  subject  to  adjustment.  In  general,  the  Rights  will  become  exercisable  and  trade  independently
from the common stock on a distribution date that will occur on the earlier of (i) the public announcement
of  the  acquisition  by  a  person  or  group  of  15%  or  more  of  the  common  stock  or  (ii)  ten  days  after
commencement of a tender or exchange offer for the common stock that would result in the acquisition of
15%  or  more  of  the  common  stock.  Upon  the  occurrence  of  certain  other  events  related  to  changes  in
ownership of the common stock, each holder of a Right would be entitled to purchase shares of common
stock,  or  an  acquiring  corporation’s  common  stock,  having  a  market  value  of  twice  the  exercise  price.
Under certain conditions, the Rights may be redeemed at $0.01 per Right by the Board of Directors. The
Rights expire on September 25, 2008.

INCYTE CORPORATION

Note  11.  Stock  Compensation

We adopted SFAS 123R on January 1, 2006. SFAS 123R requires the recognition of the fair value of
stock compensation in the statement of operations. We recognize the stock compensation expense over the
requisite  service  period  of  the  individual  grants,  which  generally  equals  the  vesting  period.  Prior  to
January  1,  2006,  we  followed  APB  Opinion  25,  Accounting  for  Stock  Issued  to  Employees,  and  related
interpretations in accounting for our stock compensation.

We  elected  the  modified  prospective  method  in  adopting  SFAS  123R.  Under  this  method,  the
provisions of SFAS 123R apply to all awards granted or modified after the date of adoption. In addition,
the unrecognized expense of awards not yet vested at the date of adoption is recognized in net income in
the periods after the date of adoption using the same valuation method (Black-Scholes) and assumptions
determined  under  the  original  provisions  of  SFAS  123,  Accounting  for  Stock-Based  Compensation,  as
disclosed in our previous filings.

Under  the  provisions  of  SFAS  123R,  we  recorded  $10.1  and  $8.9  million,  respectively,  of  stock
compensation expense on our audited condensed consolidated statement of operations for the year ended
December 31, 2007 and 2006. We utilized the Black-Scholes valuation model for estimating the fair value
of the stock compensation granted, with the following weighted-average assumptions:

The risk-free interest rate is derived from the U.S. Federal Reserve rate in effect at the time of grant.
The expected life calculation is based on the observed and expected time to the exercise of options by our
employees based on historical exercise patterns for similar type options. Expected volatility is based on the
historical  volatility  of  our  common  stock  over  the  period  commensurate  with  the  expected  life  of  the
options. A dividend yield of zero is assumed based on the fact that we have never paid cash dividends and
have no present intention to pay cash  dividends.

Based  on  our  historical  experience,  we  have  assumed  an  annualized  forfeiture  rate  of  5%  for  our
options.  Under  the  true-up  provisions  of  SFAS  123R,  we  will  record  additional  expense  if  the  actual
forfeiture  rate  is  lower  than  we  estimated,  and  will  record  a  recovery  of  prior  expense  if  the  actual
forfeiture is higher than we estimated.

SFAS  123R  requires  us  to  present  pro  forma  information  for  the  comparative  period  prior  to  the
adoption  as  if  we  had  accounted  for  all  our  stock  options  under  the  fair  value  method  of  the  original
SFAS 123. The following table illustrates the effect on net loss and loss per share if we had applied the fair

The  valuation  allowance  for  deferred  tax  assets  increased  by  approximately  $36.0  million,
$38.2  million  and  $48.8  million  during  the  years  ended  December  31,  2007,  2006  and  2005,  respectively.
Approximately  $61.7  million  of  the  valuation  allowance  for  deferred  tax  assets  relates  to  benefits  from
stock option deductions which, when recognized, will be allocated directly to contributed capital.

Management  believes  the  uncertainty  regarding  the  realization  of  net  deferred  tax  assets  requires  a

full valuation allowance.

As of December 31, 2007, we had federal and state net operating loss carryforwards of approximately
$804.0  million.  We  also  had  federal  and  state  research  and  development  tax  credit  carryforwards  of
approximately  $37.0  million.  The  net  operating  loss  carryforwards  and  tax  credits  will  expire  at  various
dates,  beginning  in  2008  through  2027,  if  not  utilized.  Utilization  of  the  net  operating  losses  and  credits
may  be  subject  to  an  annual  limitation,  due  to  the  ‘‘change  in  ownership’’  provisions  of  the  Internal
Revenue  Code  of  1986  and  similar  state  provisions.  We  also  had  federal  and  state  capital  loss
carryforwards of approximately $19.4 million  that  will  expire beginning in  2009.

Note 13. Net Loss Per Share

For all periods presented, both basic and diluted net loss per common share are computed by dividing
the  net  loss  by  the  number  of  weighted  average  common  shares  outstanding  during  the  period.  Stock

Note 14. Segment  Reporting

Our operations are treated as one operating segment, biotechnology drug discovery and development,
in  accordance  with  FASB  Statement  No.  131  (‘‘SFAS  131’’).  For  the  year  ended  December  31,  2007,  we
recorded revenue from customers throughout the United States and in Canada, Germany, Sweden, and the
United  Kingdom.  Export  revenues  for  the  years  ended  December  31,  2007,  2006  and  2005  were
$0.7 million, $0.6 million and $2.8 million, respectively.

Note 15. Defined Contribution Plan

We  have  a  defined  contribution  plan  qualified  under  Section  401(k)  of  the  Internal  Revenue  Code
covering all domestic employees. Employees may contribute a portion of their compensation, which is then
matched by us, subject to certain limitations. Defined contribution expense was $0.5 million, $0.0 million
and $0.5 million in 2007, 2006 and 2005, respectively.

Note 16. Litigation

Invitrogen

In October 2001, Invitrogen Corporation (‘‘Invitrogen’’) filed an action against us in the federal court
for the District of Delaware, alleging infringement of three patents. On June 15, 2006 we entered into a
settlement  agreement  with  Invitrogen  pursuant  to  which  we  agreed  to  pay  Invitrogen  $3.4  million  as  a

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

Note 16. Litigation (Continued)

settlement  fee.  This  amount  is  included  in  other  expenses  in  the  accompanying  condensed  consolidated
statements of operations for the year ended  December  31,  2006.

In addition to the matter described above, from time to time we have been involved in certain legal
actions arising in the ordinary course of business. In management’s opinion, the outcome of such actions
will not have  a material adverse effect  on  our financial position, results of operations, or liquidity.

Note 17. Related Party Transactions

The  following  summarizes  our  related  party  transactions  as  defined  by  FASB  Statement  No.  57,
Related Party Disclosures (‘‘SFAS 57’’). In each of the transactions noted in which a director of Incyte was at
the  time  of  the  transaction  in  some  way  affiliated  with  the  other  party  to  the  transaction,  such  director
recused himself from voting on the related party transaction, other than the  Senomyx, Inc.  transaction.

During  1997,  we  purchased  diaDexus  Series  B  Preferred  Stock  at  a  cost  of  $1.3  million.  We  do  not
have  the  ability  to  exert  significant  influence  over  diaDexus.  We  have  an  executive  officer  who  sits  on
diaDexus’ Board of Directors. In June 2006, we recorded an impairment charge of $1.3 million to reduce
the  carrying  value  of  this  investment  because  the  investee  had  less  than  six  months  of  cash  and  the
likelihood of future debt or equity financing  that would not result  in an impairment  was  remote.

During 2000 and 2001 we purchased shares of Series A Preferred Stock and Series C Preferred Stock
of  Genomic  Health,  Inc.  (‘‘Genomic  Health’’)  for  an  aggregate  purchase  price  of  $6.0  million.  In
connection  with  the  completion  of  its  initial  public  offering  on  October  4,  2005,  these  shares  were
converted into common shares. Additionally as part of its initial public offering, Genomic Health exercised
an  election  under  which  we  were  required  to  acquire  an  additional  $5.0  million  of  Genomic  Health
common stock. In March 2006, we sold our initial investment for $11.5 million, and in October 2006, we
sold the remaining portion of this investment for $5.8 million, which resulted in a aggregate realized gain
of  $6.2  million  for  the  year  ended  December  31,  2006.  Julian  C.  Baker,  one  of  our  directors,  is  also  a
director  of Genomic Health and holds shares, directly or  beneficially,  of  both  companies.

During 2000, we purchased shares of Series D Preferred Stock of Senomyx, Inc. (‘‘Senomyx’’) for an
aggregate  purchase  price  of  $6.5  million.  In  connection  with  the  completion  of  Senomyx’s  initial  public
offering in 2004, our ownership interest was converted into common shares. These shares were sold in 2005
for $5.7 million, resulting in a realized gain of $2.8 million from their carrying value. Frederick B. Craves,
one of our former directors, is a partner of Bay City Capital, which  held shares of  Senomyx stock.

During  2005,  we  repurchased  on  the  open  market,  and  retired,  $36.5  million  in  face  value  of  5.5%
Notes. One such transaction in 2005 involved the repurchase, at a purchase price of 98.25% of face value,
of $5.0 million in face value of such notes from a limited partnership of which Julian C. Baker, one of our
directors, is a controlling member of the general partner of the general partner and may have a pecuniary
interest.  Mr.  Baker  did  not  participate  in  our  decision  to  engage  in  such  a  repurchase  transaction.  The
price paid by us in such repurchase transaction was equal to the price paid by us to an independent third
party in a comparable transaction negotiated on an arms’-length basis a short time prior to such repurchase
transaction.

Note 18. Commitments

As  of  December  31,  2007,  we  had  noncancelable  operating  leases  on  multiple  facilities  and
equipment, including facilities in Palo Alto, California; San Diego, California; and Wilmington, Delaware.

Note 18. Commitments (Continued)

The  leases  expire  on  various  dates  ranging  from  June  2008  to  March  2011.  Certain  leases  have  renewal
options for periods ranging up to 5 years. Rent expense for the years ended December 31, 2007, 2006 and
2005, was approximately $4.6 million,  $4.4  million and $4.2 million, respectively.

As of December 31, 2007, future noncancelable minimum payments under operating leases, including

leases for sites included in the restructuring programs were as follows:

The amounts and timing of payments related to vacated facilities may vary based on negotiated timing
of  lease  terminations.  We  have  entered  into  sublease  agreements  for  our  vacated  space  with  scheduled
payments to us of $3.1 million (less than  1 year),  $4.2 million (years 1-3), and  $0.3 million (years  4-5).

In  addition  to  the  non-cancelable  commitments  included  in  the  table  above,  we  have  entered  into
contractual  arrangements  that  obligate  us  to  make  payments  to  the  contractual  counterparties  upon  the
occurrence of future events. We consider these potential obligations contingent, and have summarized all
significant arrangements below.

Commitments related to Maxia are considered contingent commitments as future events must occur
to cause these commitments to be enforceable. In February 2003, we completed our acquisition of Maxia.
Under  the  merger  agreement,  former  Maxia  stockholders  have  the  right  to  receive  certain  earn  out
amounts of up to a potential aggregate amount of $14.0 million upon the occurrence of certain research
and development milestones set forth in the merger agreement. Twenty percent of each earn out payment,
if earned, will be paid in cash and the remaining eighty percent will be paid in shares of our common stock
such that an aggregate of $2.8 million in cash and $11.2 million in our common stock (based upon the then
fair value) could potentially be paid pursuant to the earn out milestones. The milestones occur as Maxia
products  enter  various  stages  of  human  clinical  trials  and  may  be  earned  at  any  time  prior  to  the  tenth
anniversary  of  the  consummation  of  the  merger.  In  any  event,  no  more  than  13,531,138  shares  of  our
common  stock  may  be  issued  to  former  Maxia  stockholders  in  the  aggregate  pursuant  to  the  merger
agreement. None of these milestones had  been  achieved as of  December 31,  2007.

We  have  entered  into  and  intend  to  continue  to  seek  to  license  additional  rights  relating  to
compounds  or  technologies  in  connection  with  our  drug  discovery  and  development  programs.  Under
these licenses, we may be required to pay up-front fees, milestone payments and royalties on sales of future
products.

Item 9. Changes in and Disagreements With Accountants on  Accounting and Financial Disclosure

Not applicable.

Item 9A. Controls and Procedures

Evaluation of disclosure controls and procedures. We maintain ‘‘disclosure controls and procedures,’’
as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the ‘‘Exchange Act’’),
that are designed to ensure that information required to be disclosed by us in reports that we file or submit
under  the  Exchange  Act  is  recorded,  processed,  summarized,  and  reported  within  the  time  periods
specified  in  Securities  and  Exchange  Commission  rules  and  forms,  and  that  such  information  is
accumulated  and  communicated  to  our  management,  including  our  Chief  Executive  Officer  and  Chief
Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and
evaluating  our  disclosure  controls  and  procedures,  management  recognized  that  disclosure  controls  and
procedures,  no  matter  how  well  conceived  and  operated,  can  provide  only  reasonable,  not  absolute,
assurance  that  the  objectives  of  the  disclosure  controls  and  procedures  are  met.  Our  disclosure  controls
and  procedures  have  been  designed  to  meet  reasonable  assurance  standards.  Additionally,  in  designing
disclosure  controls  and  procedures,  our  management  necessarily  was  required  to  apply  its  judgment  in
evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any
disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of
future events, and there can be no assurance that any design will succeed in achieving its stated goals under
all potential future conditions.

Based on their evaluation as of the end of the period covered by this Annual Report on Form 10-K,
our  Chief  Executive  Officer  and  Chief  Financial  Officer  concluded  that,  as  of  such  date,  our  disclosure
controls and procedures were effective at  the reasonable assurance  level.

Changes in internal control over financial reporting. There was no change in our internal control over
financial  reporting  (as  defined  in  Rule  13a-15(f)  under  the  Exchange  Act)  that  occurred  during  our  last
fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control
over financial reporting.

Management’s  annual  report  on  internal  control  over  financial  reporting. Our  management  is
responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting,  as  such
term is defined in Exchange Act Rules 13a-15(f). Because of its inherent limitations, internal control over
financial  reporting  may  not  prevent  or  detect  misstatements.  Projections  of  any  evaluation  of  the
effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate  because  of
changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Our  management,  with  the  participation  of  our  Chief  Executive  Officer  and  Chief  Financial  Officer,
conducted an evaluation of the effectiveness of our internal control over financial reporting based on the
issued  by  the  Committee  of  Sponsoring
framework 
Organizations  of  the  Treadway  Commission.  Based  on  our  evaluation  under  the  framework  in  Internal
Control—Integrated  Framework,  our  management  concluded  that  our  internal  control  over  financial
reporting  was  effective  as  of  December  31,  2007.  The  effectiveness  of  our  internal  control  over  financial
reporting  as  of  December  31,  2007  has  been  audited  by  Ernst  &  Young  LLP,  an  independent  registered
public accounting firm, as stated in their  report  which is included herein.

Report of Independent Registered Public  Accounting Firm

The Board of Directors and Stockholders of  Incyte Corporation

We  have  audited  Incyte  Corporation’s  internal  control  over  financial  reporting  as  of  December  31,
2007, based on criteria established in Internal Control—Integrated Framework issued by the Committee of
Sponsoring  Organizations  of  the  Treadway  Commission  (the  COSO  criteria).  Incyte  Corporation’s
management  is  responsible  for  maintaining  effective  internal  control  over  financial  reporting,  and  for  its
assessment of the effectiveness of internal control over financial reporting included in the accompanying
Management’s  Annual  Report  on  Internal  Control  Over  Financial  Reporting.  Our  responsibility  is  to
express an opinion on the company’s  internal control over financial reporting based on  our audit.

We  conducted  our  audit  in  accordance  with  the  standards  of  the  Public  Company  Accounting
Oversight  Board  (United  States).  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain
reasonable assurance about whether effective internal control over financial reporting was maintained in
all  material  respects.  Our  audit  included  obtaining  an  understanding  of  internal  control  over  financial
reporting,  assessing  the  risk  that  a  material  weakness  exists,  testing  and  evaluating  the  design  and
operating  effectiveness  of  internal  control  based  on  the  assessed  risk,  and  performing  such  other
procedures  as  we  considered  necessary  in  the  circumstances.  We  believe  that  our  audit  provides  a
reasonable basis for our opinion.

A  company’s  internal  control  over  financial  reporting  is  a  process  designed  to  provide  reasonable
assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for
external  purposes  in  accordance  with  generally  accepted  accounting  principles.  A  company’s  internal
control over financial reporting includes those policies and procedures that (1) pertain to the maintenance
of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the
assets  of  the  company;  (2)  provide  reasonable  assurance  that  transactions  are  recorded  as  necessary  to
permit  preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting  principles,
and that receipts and expenditures of the company are being made only in accordance with authorizations
of management and directors of the company; and (3) provide reasonable assurance regarding prevention
or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have
a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk
that controls may become inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

In our opinion, Incyte Corporation maintained, in all material respects, effective internal control over

financial reporting as of December 31, 2007, based on the  COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight
Board (United States), the consolidated balance sheets of Incyte Corporation as of December 31, 2007 and
2006,  and  the  related  consolidated  statements  of  operations,  comprehensive  loss,  stockholders’  equity
(deficit)  and  cash  flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2007  of  Incyte
Corporation and our report dated February 26, 2008  expressed  an  unqualified  opinion thereon.

STOCK PRICE PERFORMANCE GRAPH

The  following  graph  illustrates  a  comparison  of  the  cumulative  total  stockholder  return  (change  in
stock  price  plus  reinvested  dividends)  of  the  Company’s  Common  Stock,  the  Total  Return  Index  for  the
NASDAQ U.S. Stocks (the ‘‘NASDAQ Composite Index’’), and the Total Return Index for the NASDAQ
Biotechnology Stocks (the ‘‘NASDAQ Biotechnology Index’’) assuming an investment of $100 in each on
December 31,  2002.  In  previous  years,  the  Company  used  the  Total  Return  Index  for  the  NASDAQ
Pharmaceutical Stocks (the ‘‘NASDAQ Pharmaceutical Index’’) as a comparative index, and that index is
also  presented  below  for  comparison  purposes.  The  Company  elected  to  change  the  comparative  index
from  the  NASDAQ  Pharmaceutical  Index  to  the  NASDAQ  Biotechnology  Index  because  the  Company
believes  it  better  represents  the  Company’s  peer  group  engaged  in  a  similar  line-of-business.  The
Company’s  Common  Stock  is  traded  on  the  NASDAQ  Global  Market.  The  graph  is  required  by  the
Securities  and  Exchange  Commission  and  is  not  intended  to  forecast  or  be  indicative  of  possible  future
performance of the Company’s Common  Stock.

Except for the historical statements contained herein, the statements contained in this annual report, including without limitation, statements as to our

expedited review for our JAK inhibitor for myelofi brosis, our expectations with respect to our development plans and program objectives for 2008, 
plans to present and disclose data from our clinical trials, the potential benefi ts and effectiveness of our compounds in treating disease, and our plans 
to  seek  strategic  partnerships  or  out-licensing  opportunities  and  to  commercialize  certain  programs  on  our  own,  are  forward-looking  statements

ability to enroll a suffi cient number of patients for our clinical trials, unanticipated delays in programs or uses of capital, and other risks discussed in
