ITEM  1.  BUSINESS

Overview

We  believe that we are a leader in the discovery and validation of high-quality
novel  targets for several major human diseases and a leader in the discovery of
potential  new  drug  therapies, specifically for cancer and other proliferative
diseases.  Our  primary  mission is to develop proprietary human therapeutics by
leveraging  our  integrated discovery platform to increase the speed, efficiency
and  quality  of  pharmaceutical  product  discovery  and  development.

Through  our expertise in comparative genomics and model system genetics, we are
able  to  find new drug targets that we believe would be difficult or impossible
to  uncover  using  other  experimental  approaches. Our research is designed to
identify  novel  genes and proteins expressed by those genes that, when changed,
either  decrease  or  increase  the  activity in a specific disease pathway in a
therapeutically  relevant  manner.  These  genes  and  proteins represent either
potential  product  targets  or  drugs that may treat disease or prevent disease
initiation  or  progression.

Specifically  in cancer, the remarkable evolutionary conservation of biochemical
pathways strongly supports the use of simple model systems, such as fruit flies,
nematode  worms,  zebrafish  and  mice,  to  identify key components of critical
cancer  pathways  that  can  then  be  targeted for drug discovery. We expect to
develop  new  cancer drugs by exploiting the underlying "genetic liabilities" of
tumor  cells  to  provide  specificity in targeting these cells for destruction,
while  leaving  normal  cells  unharmed.  We  have  discovered  and  are further
developing  a  number  of  small molecule drug targets in addition to monoclonal
antibody  drug targets. Molecules directed against these targets may selectively
kill  cancer  cells  while  leaving  normal  cells  unharmed,  and  may  provide
alternatives  to  current  cancer  therapies.

While  our  primary  focus is on drug discovery and development, we believe that
our proprietary technologies are valuable to other industries whose products can
be  enhanced by an understanding of DNA or proteins, including the agrochemical,
agricultural  and  diagnostic  industries. Many of these industries have shorter
product  development  cycles  and  lower  risk than the pharmaceutical industry,
while  at  the  same  time  generating  significant sales with attractive profit
margins. By partnering with companies in multiple industries, we believe that we
are  able  to diversify our business risk, while at the same time maximizing our
future  revenue  stream  opportunities.

Clinical  Pipeline

In  2002,  we  made  considerable progress in advancing our clinical development
pipeline.  We  entered into relationships providing for clinical supplies of our
rebeccamycin  analogue  in anticipation of initiating Company sponsored clinical
studies.  In addition, we continued to advance preclinical candidates, including
XL  784,  in  anticipation  of filing our first investigational new drug ("IND")
application  for  a  proprietary  compound.

Rebeccamycin  Analogue  (XL  119).  Our  most  advanced  clinical program is the
rebeccamycin  analogue,  an  anticancer  compound  that  we  in-licensed  from
Bristol-Myers  Squibb  Company  ("Bristol-Myers  Squibb"  or "BMS") in 2001. The
rebeccamycin  analogue  has  completed  Phase  I  clinical testing. The Phase II
clinical  testing  program,  which  is  being  conducted  by the National Cancer
Institute  ("NCI"),  is  well advanced. The compound has been studied in a broad
range  of tumors. The safety profile appears manageable and consistent with that
of  other  cytotoxic  agents,  and  generally  includes  myelosuppression  and
neutropenia.  These  side  effects  are  largely  transient  and reversible when
treatment  is  stopped.  To  date,  the  most  pronounced antitumor activity was
observed  in  upper  gastrointestinal  tumors  (most  prominently  in  bile duct
tumors),  where  several  partial  responses  and instances of prolonged disease
stabilization  occurred.  Based  on  these results, we believe that the compound
deserves further development efforts, as there is currently no approved standard
therapy  for  these  rapidly  progressing  tumors. We anticipate initiating next
development  steps,  if  any,  following  discussions  with  the  Food  and Drug
Administration  ("FDA"). The NCI may also expand its Phase II program to include
additional  tumor  types  or  combination  studies. Drug substance to be used in
Company-sponsored  clinical  trials  has  been  manufactured  in  bulk supply by
third-party  suppliers. We expect that the available supply of the compound will
be  sufficient  to  support our clinical needs as well as any trials that may be
initiated  by  the  NCI.

XL  784.  XL  784  is  the  first  small  molecule  compound  developed from our
proprietary drug discovery platform. The target against which XL 784 is directed
was  originally  discovered  in our anti-angiogenesis research program, although
the  actual  mechanism  by  which  the compound exerts its anti-tumor effects is
still being explored. We are currently completing regulatory toxicology studies,
and if the safety profile continues to look acceptable, we expect to file an IND
in  2003. Our clinical plans include initiating Phase I first-in-man studies, to
be conducted in healthy volunteers, while we continue to explore the therapeutic
utility  of  the  compound  in  various  animal  models  of  disease,  including
cardiovascular  disease.

2002  Corporate  Collaborations

We  have  established  several  commercial  collaborations  with  leading
pharmaceutical  and biotechnology companies as well as agriculture companies. In
October  2002,  Exelixis and SmithKlineBeecham Corporation ("GlaxoSmithKline" or
"GSK")  formed  a  broad  alliance  to discover, develop and commercialize novel
therapeutics  in the areas of vascular biology, inflammatory disease and cancer.
The  alliance  combines  our  powerful gene-to-drug discovery platform and GSK's
strengths  in  development and commercialization by means of an innovative model
for  sharing  risks  and  potential  rewards  in  a  research  and  development
collaboration.  Under  the terms of the arrangement, we will have responsibility
for  the  delivery  to GSK of small molecule compounds that have met agreed-upon
criteria  in early Phase II clinical testing. GSK will have the right to further
develop  these  compounds  and  exclusive,  worldwide  commercialization  and
manufacturing  rights.  We  retain  co-promotion  rights  in  North  America for
molecules  selected  for  development  by  GSK.

In  August  2002,  we  agreed to a two-year extension of our mechanism of action
("MOA")  collaboration  with  BMS,  which  was  established  in 1999. Under this
collaboration,  we  identify  and validate important biological targets directly
affected  by  selected  BMS  compounds. This collaboration is in addition to the
broad  alliance established with BMS in 2001 focused on cancer target discovery,
which  is  ongoing.

In  December  2002,  our  joint  venture  with  Bayer  CropScience  LP  ("Bayer
CropScience,"  formerly,  Aventis  CropScience  USA  LP, "Aventis CropScience"),
Agrinomics  LLC,  established  a collaboration with Renessen LLC to enhance seed
oil content in commercially valuable seed oil crops. Renessen is a joint venture
between  Monsanto  Company  and  Cargill,  Inc.  The  collaboration  combines
Agrinomics'  technological  leadership  in  agricultural  functional  genomics,
high-throughput  gene  screening  and  seed  trait  identification, developed by
Exelixis, with Renessen's global expertise in quality trait crop development and
commercialization,  with  the  goal  of  accelerating  the  development of novel
proprietary  crops  with  improved  seed  composition traits. This collaboration
leverages the unique capabilities of Agrinomics' powerful ACTTAG trait selection
platform to rapidly discover and validate genes that can optimize important seed
traits and potentially increase the commercial value of many of the world's most
significant  agricultural  crops.

At the beginning of 2002, we established a combinatorial chemistry collaboration
with  Merck  &  Co., Inc. ("Merck") for the joint design and generation of small
molecular  compound  libraries  for  high-throughput  drug  screening.  The
collaboration  pairs  our expertise in combinatorial library design with Merck's
synthetic  chemistry  expertise  with  the  goal of achieving optimal diversity,
density,  novelty  and  quality  in  library  production.  This collaboration is
similar  to  our other combinatorial chemistry collaborations with Cytokinetics,
Inc.,  Elan  Pharmaceuticals,  Inc.,  Scios  Inc.  and  Schering-Plough Research
Institute,  Inc.,  and  provides  licensing  fees  and  payments for delivery of
specified  numbers  of  compounds  meeting  certain  quality-assurance criteria.

In  addition  to our commercial collaborations, we have relationships with other
biotechnology  companies, academic institutions and universities that provide us
access  to  specific  technology or intellectual property for the enhancement of
our  business.  These  include collaborations with leading biotechnology product
developers  and  solutions  providers, among them Affymetrix Inc., GeneMachines,
AVI  BioPharma,  Inc.,  Silicon  Genetics,  Galapagos NV, Genomics Collaborative
Inc.,  Accelrys,  Inc.,  Akceli,  Inc.,  Ardais Corp., Cogen BioCognetics, Inc.,
Impath  Predictive  Oncology,  Inc.  and  Virtual  Arrays,  Inc.

In  June  2002,  we  established  a collaboration with Merck for the creation of
customized  genetically  engineered  mouse  models  of  disease  based  on  our
proprietary  Conditional gene targeting technology. Under the agreement, we will
seek  to  create  a specified number of customized mouse models based on Merck's
genetic  specifications.  Conditional  gene  targeting  permits  highly specific
temporal  and  spatial  control  over  gene  inactivation  for  the  creation of
precisely  controlled,  information-rich  mammalian  models  of  disease.

Following  the  completion of our acquisition of Genomica Corporation in January
2002,  we  granted  exclusive  third- party commercial and development rights to
Genomica's  software  assets  to  Visualize,  Inc., a provider of sophisticated,
interactive data visualization software serving the financial services industry.
We  have a revenue sharing agreement with Visualize, pursuant to which we retain
the  right  to  receive  and use the Genomica software as well as any derivative
works  created  by  Visualize  for  our  internal  use.

Industry  Background

Conventional  chemical  drug discovery involves a series of steps, many years of
work  and  substantial  resources.  Initially,  scientists  identify  potential
molecular  targets  for  therapeutic  intervention.  These  targets must then be
validated,  or demonstrated to be able to affect the disease biochemistry. Next,
the  validated  target  is put through a series of assays, or tests, to identify
chemical compounds that would modulate the activity of the target. Once chemical
compounds  that modify the activity of the target are identified, they must then
be  iteratively  optimized  through synthetic chemistry processes. After several
iterations,  the resulting compounds are tested in animal models of disease, and
selected  lead  compounds  are  then  considered  for  preclinical  development.

Many  of  the  principal  products  of  the  pharmaceutical  and  biotechnology
industries  were  developed  without  knowledge about the underlying genetic and
biochemical causes of disease, or without knowledge of how the drug works in the
body.  This limited knowledge about the target or MOA of the product can lead to
somewhat  random  and/or  suboptimal  product  candidates.  Similar  issues  are
problems  for  the  agrochemical,  agricultural  and diagnostic industries. As a
result,  product  development  in  all  of  these  industries  is  costly,  time
consuming,  inefficient  and characterized by high failure rates. Many companies
have  turned to genomic technologies, primarily for DNA sequence information, to
help  address  these  problems  with  respect  to  the selection of molecular or
gene-based  targets.

Despite  significant  investment  in genomics and the recent availability of the
human  genome  sequence, there has not been appreciable improvement in selecting
high  quality  molecular  targets  for  drug  development.  Notwithstanding  the
tremendous  advances  in  providing  genomic  data,  it is clear that a rational
selection  of  molecular  targets  requires  more detailed or specific knowledge
about  the  function  of  genes  and  their  encoded  proteins  as well as their
interaction  with  other  components  of  signaling  networks,  or  biochemical
pathways.  Since  the  complete  human  sequence  and  the  sequences  of  other
commercially  important  genomes  are  now  available,  we  believe  that  the
competitive  advantage  for  companies  going  forward  will  be  the ability to
identify  the  small  number  of significant gene targets, within the very large
number  of  genes,  which  when  modulated  will result in a therapeutically and
commercially  valuable  outcome.  By  integrating our superior ability to select
biological  targets  with  a state-of-the-art drug discovery platform, we expect
our  platform  and  biological insights to produce novel targets and potentially
innovative  products.

Our  Strategy

Our  business  strategy  is  to leverage our biological expertise and integrated
drug  discovery capabilities to improve the speed, efficiency and quality of the
discovery,  development and commercialization process for human therapeutics and
other  products.  Specifically  our business strategy includes the following key
elements:

MAINTAIN  AND  AUGMENT  BIOLOGICAL  EXPERTISE: Our biological expertise is a key
competitive  advantage  that  we  believe  applies throughout all aspects of our
collaborative  relationships  and drug discovery efforts. We seek to continually
enhance  our  technology  platform  through  building, in-licensing or acquiring
technologies  that complement our fundamental knowledge and capabilities as well
as  through  protecting  our  proprietary  technologies  with  patents and trade
secrets.

SELECTIVELY  DEVELOP THERAPEUTIC PRODUCTS: We have invested and plan to continue
to  invest significant funds in discovering and developing proprietary products,
particularly  in  the area of cancer. We have committed substantial resources to
building  a world-class drug discovery effort that is integrated with our unique
understanding  of  the  biological basis of disease, and we expect to generate a
pipeline  of  compounds  to  move  into  clinical  trials.

LEVERAGE STRATEGIC COLLABORATIONS: We have established and intend to continue to
pursue  commercial relationships and key partnerships with major pharmaceutical,
biotechnology  and  agrochemical  companies  based  on  the  strength  of  our
technologies,  biological  expertise  and  drug  discovery  capabilities.  These
collaborations  provide  us  with  a  substantial  committed  revenue  stream in
addition  to  opportunities  to  receive  significant  future  payments,  if our
collaborators  successfully  develop  and  market  products that result from our
collaborative work. In addition, many of our collaborations have been structured
strategically  so  that  we  gain access to technology or product opportunities.
Technology  access  allows  us  to  more  rapidly advance our internal programs,
saving  both  time and money, while at the same time retaining rights to use the
same  information  or tools in different industries or for different development
opportunities.

ACQUIRE  PRODUCTS  AND  TECHNOLOGIES  OPPORTUNISTICALLY: We continually evaluate
opportunities  that  may  provide  us with key personnel, intellectual property,
technologies  and  products  that  will enhance our development capabilities and
product  pipeline. We believe that through the acquisition of strategic products
and  technologies we will be able to create additional value in our internal and
collaborative  programs.  In  addition,  we believe that many of these strategic
relationships  will  permit  us  to obtain co-development, co-promotion or other
rights  to  products identified or developed in such collaborative relationships
as  a  result  of  our  efforts.

Integrated  Research  And  Discovery  Technologies

We  have  developed  an integrated research and discovery platform that includes
proprietary  technologies  and  know-how.  This  platform  includes model system
genetics  and  comparative  genomics,  libraries  of  modified  model organisms,
specialized  reagents,  assay  biology,  informatics databases and software, MOA
technology,  automated  high-throughput screening, a growing compound library in
excess  of  approximately  three  million small molecule compounds and extensive
medicinal/combinatorial  chemistry capabilities. Using this integrated platform,
we  are  able  to  effectively  and  rapidly  identify novel targets and develop
proprietary  compounds.  We  believe  that  a  key  competitive advantage is the
breadth  of  our  platform  as  well as our ability to apply the tools of modern
biology  and  chemistry  to  address  commercially  relevant  questions.

     Model  System  Genetics  and Comparative Genomics. Model system genetics is
the  study  of  simple  biological  systems  to  discover  genes,  proteins  and
biochemical pathways that may be useful in the development of new pharmaceutical
or  agricultural  products.  Our  primary  model  systems  are the fruit fly, D.
melanogaster; the nematode worm, C. elegans; the zebrafish, D. rerio, corn smut,
Ustilago  maydis;  Arabidopsis  thaliana;  and  the  micro-tomato,  Lycopersicon
esculentum.  Empirical  evidence  has  provided  us with accurate benchmarks for
applying biological and biochemical discoveries from these model systems to more
developed  organisms,  such  as  humans  or  commercial  crops.

Scientists  have  used these organisms as research tools for several decades. We
have industrialized the analysis of these model systems by developing a suite of
proprietary  tools  and  reagents  that  allow  us to perform systematic genetic
analyses  at  a larger scale and with substantially greater speed than otherwise
are  currently  available.  Among  other  proprietary tools, we have exclusively
licensed  the  U.S.  patent  covering  P-element,  which  is  a  genetic element
essential  for  performing  modern  fruit  fly  genetics.

Comparative  genomics  is  the  application  of data learned from one biological
system  to another system. For example, the use of the angiogenesis pathway data
learned  from  a  zebrafish  can  be  applied  to  studying  human angiogenesis.
Application of comparative genomics relies on the use of our extensive libraries
of  model  organisms,  the  proprietary databases of information and informatics
methods  generated  by  our  scientists,  as  well as access to state-of-the-art
technological  tools  such as RNA interference (RNAi). Each of our model systems
has  unique  advantages  that  can  be  applied  in  different  ways  to address
commercially  relevant  questions  in a rapid manner. Our expertise allows us to
use  knowledge  across  species  and  to  select  the  best  model systems for a
particular  commercial  application.

     Proprietary  Model Organism Libraries. We have produced and maintain as key
strategic assets populations of well-characterized genetically modified organism
libraries, and the process for their production and use is a core technology. We
have  libraries  of  these organisms that have been modified and catalogued in a
systematic  fashion,  so  that  comprehensive pair-wise breeding can allow us to
test  the  effects  of  gene  alteration  or  modulation  on a specified disease
condition. Through the use of these libraries, we are able to rapidly assess the
effect  of  increasing  or  decreasing  the  output  of  each  gene in the model
organism. The availability of these assets significantly enhances the efficiency
of  research  directed at drug or agricultural product target identification, as
our  model  systems permit results to be obtained in a period of weeks or months
from  the  inception  of  the  research  effort.  We believe that our ability to
rapidly  and  selectively  move  from  an  alteration  in a gene directly to the
identification  of  validated targets that can reverse or enhance the effects of
that  alteration  is  an  extremely  powerful,  rapid  and  direct  route to new
pharmaceuticals  and  agricultural  products.

     High-throughput  Screening  (HTS)  Assays for Target and Lead Discovery. We
also  develop  proprietary genetic, biochemical and cell-based assays for use in
screening  for  potential targets, proteins and products. An HTS assay is a test
that  may include a biochemical reaction or cell-signaling event that is readily
measured,  miniaturizable  to  a  specific format and subject to automation. HTS
assays  must  meet  these  criteria  in  order  to  address the large numbers of
experimental  measurements  that  we  have  identified  in  order  to screen our
extensive  collection  of  compounds.  We  believe that we have also established
world-class expertise in gene cloning, protein expression, scale-up fermentation
and  protein purification necessary to meet these needs. Genetic assays are used
to measure the ability of a particular gene or protein to change or regulate the
disease  pathway  of  interest,  which  leads  to  the identification of disease
pathway  genes  as  well  as  those  genes  that  may  be  product  targets. The
development  of  biochemical  assays  requires  the  production  of  target gene
products  (proteins)  in sufficient quantity to support hundreds of thousands of
individual  measurements.  Cell-based  assays  may  also  require  genetically
engineered  cells  that  over-express  the  target  gene  of  interest.

     Informatics.  We have state-of-the-art informatics tools, many of which are
proprietary,  and  expertise that have been developed as an integral part of our
model  systems  genetics  and  comparative  genomics  capabilities.  These tools
include  a  broad range of applications such as: tracking samples and harvesting
data  in  the  context  of  high-throughput,  automated data collection systems;
creating discovery platforms for storing, managing and querying large data sets;
and  analysis,  curation  and  prediction  of function relative to compounds and
macromolecules.  We  believe  that  these  tools are essential to developing our
target  and  drug  discovery  pipelines  and represent a substantial competitive
advantage.  Specific  examples  include  extensive  databases and software tools
related  to:  DNA  sequencing  and  gene  discovery; generation of comprehensive
genetic  knockout  collections;  functional identification and classification of
novel  protein sequences; and design, characterization and selection of compound
libraries.  Our  informatics  capabilities  provide  an  extensive  and  readily
accessed  informational base for analyzing and comparing data produced using our
core  technologies,  allowing  us  to  optimize  and  prioritize among potential
targets  and,  downstream,  drugs  directed  against  those  targets.

     Sequencing,  Proteomics  and  Transcriptional  Profiling.  We have built or
in-licensed  significant expertise in sequencing, proteomics and transcriptional
profiling.  Our  sequencing  capacity  is  currently 1.5 million lanes per year,
scalable  to ten million lanes in our current facility. We have state-of-the-art
robotics,  advanced  laboratory information management systems, polymerase chain
reaction,  or  PCR,  mass  spectrometry  and gene cloning expertise as well as a
significant  proteomics effort to complement the existing proficiency in genetic
target  discovery.  We  have  brought  in  several  different  methods  of
transcriptional  profiling, both to validate our biological target discovery and
to  screen  for  toxicities.

     HTS,  Combinatorial  and  Medicinal  Chemistry. Our gene discovery platform
provides  novel,  biologically  validated  therapeutic  and agricultural targets
without  bias  towards conventional target classes. Thus, in addition to targets
that  are  known  in  the  industry  to be "druggable," such as protein kinases,
proteases  and  g-protein  coupled receptors, or GPCRs, many other novel classes
are identified in genetic screens that may require specialized assay technology.
We focus on finding diverse drug discovery targets in multiple assay formats. We
have established a high-throughput screening laboratory in which we conducted 22
target  screens  against millions of compounds in 2002. Through our relationship
with  BMS, we have gained access to their proprietary combinatorial hardware and
software  systems.  We  are  currently  synthesizing  hundreds  of  thousands of
compounds  per month. In addition, we have built extensive capabilities into our
high-throughput  drug  discovery  platform,  including  crystallography,  cell
biology,  medicinal  chemistry,  ADME,  pharmacokinetics,  pharmacodynamics,
pharmacology  and  chemi-informatics,  to  potentially  identify  and  develop
innovative  drugs.

     Extensive  Compound Library. We have rapidly assembled a growing collection
of  over  approximately  three  million  highly  diverse,  quality  controlled,
drug-like,  small  molecule  compounds  for  lead  discovery  by high-throughput
screening.  Today,  these  compounds  are  largely  derived  from  internal
combinatorial  synthesis.  We  believe  that  we  are  capable  of  generating
approximately  one  million  new compounds per year to add to our highly diverse
screening  library.  In  prior  years, compounds were identified for acquisition
from  external  vendors based on structural complexity and diversity, purity and
price. Over one million compounds were originally selected for acquisition using
this  analysis.  We believe that the continued expansion of our compound library
will  increase  the  frequency  and  quality  of  generating  highly active lead
compounds.

     Clinical  Development  Capabilities. In 2002, we significantly expanded our
clinical  development capabilities, staffing and infrastructure. Our development
group  is  comprised  of  experienced  professionals  with  the  expertise  and
experience  to quickly move our development candidate compounds from preclinical
testing  to  IND status and through "proof of concept" Phase II clinical trials.
The  development  group  possesses critical expertise in the areas of chemistry,
manufacturing and controls ("CMC"), pre-clinical testing, clinical trial design,
management and analysis and regulatory affairs. Therapeutic expertise within the
group  includes major disease areas such as allergy-immunology, anti-infectives,
cardiovascular,  central  nervous  system,  metabolic diseases and oncology. The
development  group  has  primary  responsibility  for advancing and managing the
progress of our clinical pipeline, including possibly initiating Phase II trials
for  our  rebeccamycin  analogue  as  a  potential  treatment  for  upper
gastrointestinal tumors, advancing XL 784 into Phase I, first-in-man trials, and
preparing  for  filing  additional INDs, consistent with our corporate goals and
corporate  collaboration  obligations.

Areas  Of  Expertise

     Human  Therapeutics

ANGIOGENESIS  AND  VASCULAR  BIOLOGY.  Angiogenesis  is  the  formation of blood
vessels.  The  ability to block the formation of new blood vessels could be used
to  kill cancer cells by depriving them of nutrients. Similarly, anti-angiogenic
agents  can  be  used  to  treat  or  prevent  diabetic  retinopathy,  macular
degeneration  and psoriasis. Products that promote angiogenesis could be used to
treat  coronary heart disease and stroke. We have an active program to study the
zebrafish  and  Drosophila  (fruit  fly)  model systems in order to identify key
angiogenic  and  anti-angiogenic gene targets and proteins. Our lead proprietary
compound,  XL 784, was discovered in our angiogenesis research program. In 2002,
we  entered  into  a  significant  small  molecule  discovery  and  development
collaboration  with GlaxoSmithKline that includes angiogensis, vascular biology,
inflammation  and  areas  of  cancer  that are not otherwise subject to existing
collaborations.

CANCER.  Cancer  is  a  leading cause of death in developed countries. Cancer is
caused  by  a  number  of genetic defects in cells resulting in unregulated cell
growth. We have discovered and are further developing a number of small molecule
drug  targets,  in  addition  to  monoclonal  antibody  drug  targets,  that may
selectively  kill  cancer  cells  while  leaving  normal cells unharmed, and may
provide  alternatives  to current cancer therapies. By exploiting the underlying
"genetic liabilities" of tumor cells, we have identified numerous targets within
specific  cell  growth  and  proliferation  regulatory  pathways  and are in the
process  of validating these targets in cell-based assays. In 2002, we completed
22  high-throughput screens directed against proprietary cancer targets. We have
established  major  cancer research collaborations with Bristol-Myers Squibb and
Protein  Design  Labs  ("PDL").  Our  lead  compound,  XL  784, has demonstrated
anti-tumor activity and is advancing toward clinical study. In 2001, through our
cancer  collaboration  with  BMS,  we  in-licensed  an  anticancer compound, the
rebeccamycin  analogue,  that  is  in  Phase  II  clinical  trials  in  upper
gastrointestinal tumors being conducted by the National Cancer Institute and for
which  we  expect  to  possibly initiate  Company-sponsored  trials.

INFLAMMATION.  Our inflammation program focuses on the role of the innate immune
system,  especially  macrophages,  in  mediating  the  inflammatory  response.
Misregulation  of  the innate immune system is of central importance in diseases
of  inflammation,  such  as  asthma  and arthritis. Drosophila displays a robust
innate immune response, and their macrophages are regulated by the same effector
molecules  and  pathways  that  regulate  human macrophages. Unlike vertebrates,
however,  they  lack  an  adaptive  immune  system,  which  allows  for  more
straightforward  analysis of the innate response. Drosophila is therefore useful
for  rapidly identifying prospective targets for treating immunological disease.
Novel  targets can also be validated in zebrafish, which has all the immune cell
types  of  mammals, with the advantage of more rapid analysis. We are working in
collaboration  with  various  universities  to  identify  targets  that  control
inflammation  and  have  identified  several  targets  to  date.

METABOLIC  DISEASES.  Metabolic  diseases  include  such important conditions as
cardiovascular diseases, diabetes and obesity, which represent significant unmet
medical needs. We have an internal program focusing on metabolic diseases as the
result  of  the  conclusion  of  a  three-year  sponsored  research program with
Pharmacia  Corporation  (Pharmacia),  which  formally  ended in February 2002 by
mutual  consent.  The  most  advanced  targets from that program were focused on
optimizing  the  levels  of  both cholesterol and fat in the bloodstream, and we
have  identified  several targets for ourselves that may be useful in developing
products  to  control Type II diabetes. We have exclusive rights to the research
work  done under the program with Pharmacia outside of certain targets that they
have  selected  under  the program, for which we will receive milestone payments
and  royalties  for  further  development  by  Pharmacia.

CENTRAL  NERVOUS  SYSTEMS  (CNS)  DISORDERS.  CNS  disorders  include  cognitive
disorders such as Parkinson's disease, depression, schizophrenia and Alzheimer's
disease.  In  our  collaboration  with  Pharmacia, we were applying our genetics
technologies  to  understand  the  causes of Alzheimer's disease. As a result of
genetic  screens  performed  to date, Pharmacia selected a number of targets for
which  we  have  received  milestone  payments  and may receive royalties in the
future.  In  2002, we published in Developmental Cell a seminal paper concerning
the  discovery  of  two  proteins,  aph-1 and pen-2, that may play a role in the
production  of  beta-amyloid,  the main constituent of senile plaques associated
with  Alzheimer's  disease.

MECHANISM  OF  ACTION  PROGRAM.  In  this  program,  we  identify  the  MOA  for
pharmaceutical compounds that have interesting biological activity but for which
the molecular target is unknown. The targets are identified through the analysis
of model organisms that are either resistant or hypersensitive to the biological
activity  produced  by  the  compound. Following identification, the targets are
confirmed  using  biochemical  assays.  Targets  and  other  components  of  the
signaling  pathways  are  then  identified  as  candidates  for further compound
development.  We have an ongoing MOA collaboration with BMS pursuant to which we
would  receive  milestone  payments and royalties for further development of the
BMS  compounds  against  the  targets  identified.

     Agriculture

FUNGICIDES  AND  HERBICIDES.  We  are  developing  fungal  and  herbicidal model
systems,  which  we intend to use to identify targets that will potentially lead
to  the  development  of  new, more effective fungicides and herbicides. We have
entered into a MOA agreement with Dow AgroSciences pursuant to which we identify
targets  for  specific  fungicide and herbicide compounds with unknown molecular
targets.

INSECTICIDES  AND NEMATICIDES. Currently, there are no products that effectively
and  safely control nematodes and their effects on plant crops. In collaboration
with  Bayer,  we  are  applying our model systems platform and assay development
capabilities  to  identify  unique targets that may be used to develop new, more
effective,  broad-spectrum  insecticides  as well as nematicides. As a result of
screening  targets both from de novo targets as well as from determining the MOA
of  an  existing  compound,  we  have  delivered  to  Bayer numerous targets and
high-throughput  screening  assays  that  may  be  useful  in  identifying  new
insecticides  for  which  we  have  received  milestone  payments.  Under  our
collaborative  arrangement  (through  our  joint  venture, Genoptera LLC), Bayer
retains exclusive rights to insecticides and nematicides for crop protection. We
remain  free  to  conduct  research  in  pesticides  other  than insecticides or
nematicides,  as  well  as  in  the  development  of  pest-resistant  crops.

PLANT  TRAIT  DISCOVERY. We have developed plant model systems to identify genes
that  may  be  used to develop crops with improved internal and external traits,
including  superior yield, improved nutritional profiles and higher oil content.
In  collaboration  with  Bayer CropScience, through an equally-owned subsidiary,
Agrinomics  LLC,  we  are  working  to research, develop and commercialize novel
genes  found  through  the  proprietary  ACTTAG  gene  expression  technology in
Arabidopsis thaliana, a plant whose genome has been fully sequenced. ACCTAG gene
expression  technology  represents a method of identifying genes associated with
gain-of-function  and  loss-of-function phenotypes. Agrinomics has characterized
and  catalogued  more  than 250,000 lines of Arabidopsis, identifying nearly its
entire genome. The collection of transgenic Arabidopsis, which we believe is one
of  the largest gene libraries for this plant in the world, has the potential to
provide  extremely  important  leads  for  significant improvements in the large
commercial  seed,  oil,  protein  and  crop  protection  markets.

Corporate  Collaborations

Our  strategy  is  to  establish  collaborations  with  major  pharmaceutical,
biotechnology  and  agrochemical  companies  based  on  the  strength  of  our
technologies  and  biological  expertise  as  well  as  to  support  additional
development of our proprietary products. Through these collaborations, we obtain
license  fees  and  research  funding,  together with the opportunity to receive
milestone  payments  and  royalties from research results and subsequent product
development.  In  addition,  many  of  our  collaborations  have been structured
strategically  to  provide  us  access  to  technology  to  advance our internal
programs, saving both time and money, while at the same time retaining rights to
use  the  same  information  in  different  industries.  Our collaborations with
leading  companies in the agrochemical industries allow us to continue to expand
our  internal  development capabilities, while providing our partners with novel
targets  and  assays,  and  to  diversify our revenue stream. For the year ended
December  31,  2002,  revenue  from  two  of  our  collaborators  represented
approximately  39%  and  25%  of total revenue, respectively. For the year ended
December  31,  2001,  revenue  from  three  of  our  collaborators  represented
approximately  32%,  31%  and  15%  of total revenue, respectively. For the year
ended  December  31,  2000,  revenue  from  two of our collaborators represented
approximately  53%  and  36%  of  total  revenue,  respectively.

     Bayer  Corporation

In  December  1999,  we  established Genoptera LLC, a Delaware limited liability
company, with Bayer Corporation to develop insecticides and nematicides for crop
protection.  As  part of the formation of this joint venture, Bayer has paid us,
through  Genoptera,  license  fees and research commitment fees of $20.0 million
and  has  agreed  to  provide  eight years of research funding through 2007 at a
minimum  level  of  $10.0  million  per  year  (for a total of $100.0 million of
committed  fees  and  research support). Bayer owns 60% of Genoptera, and we own
the  remaining  40%. We did not make any capital contributions for our ownership
interest  and  have  no  obligation to fund future losses. The formation of this
joint  venture  is  an outgrowth of, and replaces, the contractual collaboration
first  established  with Bayer AG (the corporate parent of Bayer Corporation) in
May  1998.  Bayer  will  pay  Genoptera  milestones  and  royalties  on products
developed by it resulting from the Genoptera research, and we will pay Genoptera
royalties  on  certain  uses  of  technology  arising  from  such  research.

Either  Bayer  or  Exelixis  may  terminate the Genoptera research efforts after
2007.  In  addition,  Bayer may terminate the joint venture prior to 2007 or buy
out  our interest in the joint venture under specified conditions, including, by
way  of  example,  failure  to  agree  on key strategic issues after a period of
years,  the  acquisition  of  Exelixis  by  another  company  or the loss of key
personnel  that  we  are unable to replace with individuals acceptable to Bayer.

In July 2002, Bayer completed the acquisition of Aventis S.A., including Aventis
CropScience.  We  each  own 50% of Agrinomics LLC, which was established in July
1999  to  enable  the  funding  of  a collaboration originally entered into with
Aventis  CropScience.  Agrinomics  focuses  on  research,  development  and
commercialization  of products in the field of agricultural functional genomics.
Under  the  terms of the Agrinomics joint venture agreement, Bayer has agreed to
make  capital  contributions to Agrinomics in cash totaling $20.0 million over a
five-year  period. Funding by Bayer for the collaboration is scheduled to expire
in  July  2004.  We  contributed  the  ACTTAG gene identification and activation
technology, a collection of seeds generated using the ACTTAG gene identification
and activation technology techniques and expertise in molecular and cell biology
to  the  joint  venture.  In  addition,  we  perform  research  work  for  this
collaboration.  Bayer  CropScience currently provides high-throughput screening,
robotics,  microarray  and  bioinformatics technologies and support work for the
collaborative  research  efforts.

     Bristol-Myers  Squibb

In  August  2002,  we  extended  our MOA research collaboration with BMS through
August  2004. The collaboration was initially established in September 1999, and
seeks to leverage our proprietary platform and expertise in comparative genetics
and  functional  genomics  to  identify  the  targets  of compounds delivered by
Bristol-Myers  Squibb.  This  information  may  enable  Bristol-Myers  Squibb to
enhance the potency, specificity and selectivity of drug candidates and may lead
to  the  discovery  of  new  generations  of  compounds  with  attractive  drug
properties.  In connection with the collaboration, BMS originally transferred to
us  certain  combinatorial  chemistry  hardware  and  software  and  paid  us  a
technology  access  fee.  Under the terms of the extension, BMS will continue to
provide research support payments, as well as pay milestones and royalties based
on  achievements  in the research and commercialization of products based on BMS
compounds  that  are  the  subject  of  the  collaboration.

In  July 2001, we entered into a second collaboration with BMS focused on cancer
target  identification. The collaboration involves three agreements: (a) a Stock
Purchase  Agreement;  (b)  a  Cancer  Collaboration Agreement; and (c) a License
Agreement.  Under  the  terms  of  the  collaboration, BMS (i) purchased 600,600
shares  of our common stock in a private placement at a purchase price of $33.30
per  share,  for cash proceeds to us of approximately $20.0 million; (ii) agreed
to  pay  us  a $5.0 million upfront license fee and provide us with $3.0 million
per  year in research funding for a minimum of three years; and (iii) granted to
us  a  worldwide,  fully-paid,  exclusive  license  to the rebeccamycin analogue
developed by BMS, which is currently in Phase II clinical studies for cancer and
which  we  may  take  into further clinical studies. BMS has exclusive rights to
certain potential small molecule compound drug targets in cancer selected by BMS
during  the  term  of  the  research  collaboration.

     Dow  Agrosciences

In  July  2000,  we  established  a  three-year  research collaboration with Dow
AgroSciences to identify the MOA of herbicides and fungicides delivered to us by
Dow  AgroSciences.  We  do not know the identity and function of these compounds
prior  to  their  delivery.  Under  this  agreement,  we  received  access  to a
collection  of proprietary compounds from Dow AgroSciences that may be useful in
our  human  therapeutic  drug  discovery programs. We have identified targets to
certain  Dow  AgroSciences compounds that will be used to develop new classes of
fungicides  and herbicides. Dow AgroSciences pays us research funding as well as
milestone  payments  and  royalties  based  on  achievements in the research and
commercialization of these products. Unless otherwise renewed, the collaboration
will  expire  in  July  2003.

     Protein  Design  Labs

In  May  2001,  we entered into a collaboration with PDL to discover and develop
humanized  antibodies for the diagnosis, prevention and treatment of cancer. The
collaboration  will  utilize  our  model  organism  genetics  technology for the
identification of new cancer targets and PDL's antibody and clinical development
expertise  to  create  and develop new antibody drug candidates. PDL provided us
with  $4.0 million in annual research funding, which will expire as scheduled in
June 2003 and has purchased a $30.0 million convertible note. The five-year note
bears  interest at 5.75%, and the interest thereon is payable annually. The note
is  convertible  into  our common stock at a conversion price per share equal to
the  lower  of  (i) $28.175 or (ii) 110% of the Fair Market Value (as defined in
the  note)  of  a  share  of  our  common  stock  at the time of the conversion.

     Pharmacia

Our  collaboration with Pharmacia was originally established in February 1999 to
identify  targets  in  the  fields  of Alzheimer's disease, Type II diabetes and
associated  complications of metabolic syndrome. We mutually agreed to terminate
further  research in February 2002. Under the arrangement, Pharmacia purchased a
$7.5  million  equity  interest,  paid  us  a  license  fee  of $5.0 million and
milestone  payments based on target selection, provided ongoing research support
and  has  agreed  to pay us royalties in the event that products result from the
targets  that  we  identified.  Upon  termination,  we  reacquired rights to the
research  programs  in  metabolism  and  Alzheimer's disease previously licensed
exclusively  to  Pharmacia. Pharmacia retains rights to certain targets selected
prior  to  the  reacquisition  date,  subject  to  the payment of milestones for
certain  of  those  targets  selected,  and  royalties for future development of
products  against or using those targets, but Pharmacia has no other obligations
to  make  payments to us, including approximately $9.0 million in annual funding
that  would  otherwise  be  payable  for  an  additional two years if we had not
mutually  agreed  to  terminate  the  arrangement.

     Renessen

In December 2002, Agrinomics established an alliance to enhance seed oil content
in  commercially  valuable  crops with Renessen LLC. Renessen is a joint venture
between  Monsanto  Company  and  Cargill,  Inc.  The  collaboration  combines
Agrinomics'  technological  leadership  in  agricultural  functional  genomics,
high-throughput  gene  screening  and  seed trait identification with Renessen's
global  expertise  in quality trait crop development and commercialization, with
the  goal  of  accelerating  the  development  of  novel  proprietary crops with
improved  seed  composition  traits.  This  collaboration  leverages  the unique
capabilities  of  Agrinomics'  powerful  ACTTAG  gene  activation  and selection
platform to rapidly discover and validate genes that can optimize important seed
traits  in  order  to  increase the commercial value of many of the world's most
significant  agricultural  crops.

     SmithKlineBeecham  Corporation  /  GlaxoSmithKline  plc

In  October  2002,  we  entered  into  a  broad  collaboration  with GSK for the
discovery,  development  and  commercialization  of  novel  small  molecule
therapeutics  in the areas of vascular biology, inflammatory disease and cancer,
to  the  extent  not  previously  partnered.  The  collaboration  involves three
agreements:  (a)  a  Product  Development and Commercialization Agreement; (b) a
Stock  Purchase  and  Stock  Issuance  Agreement;  and  (c)  a Loan and Security
Agreement.  Under  the  Product  Development and Commercialization Agreement, we
will  conduct  research  and  development  with  the  objective of delivering to
GlaxoSmithKline  a  specified  number  of  compounds  that  have met agreed-upon
criteria  through  Phase IIa human clinical testing. GSK has an exclusive option
to  further  develop, manufacture and commercialize each of these compounds on a
worldwide  basis,  subject  to  the payment of an option exercise fee as well as
milestone  payments  and  royalties  for  further  development  of  the compound
selected.  We  retain  co-promotion rights in North America for these compounds.
Depending  on  the continued successful development of these compounds by GSK up
to  and  including  commercialization  and  the achievement of certain net sales
levels,  we  could  receive a payment upon option exercise, as well as clinical,
regulatory  and  commercialization  milestone payments, which could collectively
exceed  $105.0  million.  We would also receive royalty payments on net sales of
the  compounds  commercialized  by GSK, if any, at rates that are dependent upon
the  number  and  timing  of  compounds  delivered  to  GSK  under the alliance.

Under  the terms of the Product Development and Commercialization Agreement, GSK
has paid us $30.0 million as an upfront fee and $10.0 million in annual research
funding,  and  has  agreed  to  pay  a minimum of an additional $80.0 million in
research  and development funding over the first six years of the collaboration,
subject to GSK's right to terminate the collaboration in the event of a material
breach by us of certain provisions of the agreement, our failure to meet certain
performance  requirements  after  the  third year of the collaboration or in the
event  of  a change of control of Exelixis by a major pharmaceutical company. On
or  about  the  second  anniversary  of  the collaboration, GSK has an option to
expand the collaboration. If this expansion occurs, we would expand our research
efforts  to deliver additional compounds to GSK in the same fields. In exchange,
GSK's  research  payments and the loan facility would increase significantly and
GSK's  option  exercise  fee  for  these  additional  compounds  would  increase
significantly  over  the  originally  contemplated levels without the expansion.

Under  the  terms  of  the  Stock  Purchase  and  Stock  Issuance Agreement, GSK
purchased  2,000,000  shares  of  our  common  stock in a private placement at a
purchase  price  of  $7.00  per  share, for cash proceeds to us of approximately
$14.0  million. Under the agreement, we also have an option to sell, and GSK has
an  obligation to purchase, additional shares of our common stock at a specified
time  in  the  future  and  at  a price that is at a premium to the then current
market  price  of  our  common stock. Under the Loan and Security Agreement, GSK
provided a loan facility of up to $85.0 million for use in our efforts under the
collaboration,  and  we  borrowed $25.0 million under that agreement in December
2002.  All  loan amounts bear interest at a rate of 4% per annum and are secured
by  the  intellectual  property,  technology  and  equipment created or utilized
pursuant  to  the  collaboration.  Principal  and accrued interest become due in
installments,  beginning on or about the sixth anniversary of the collaboration,
unless  the  collaboration is earlier terminated by GSK. Repayment of all or any
of  the  amounts advanced to us under this agreement may, at our election, be in
the  form  of  our  common  stock,  subject  to  certain  conditions.

     Chemistry  Collaborations

In  2001  and  2002,  we entered into collaboration agreements with each of Elan
Pharmaceuticals,  Inc., Scios Inc., Cytokinetics, Inc., Schering-Plough Research
Institute,  Inc.  and Merck & Co., Inc. to jointly design custom high-throughput
screening  compound  libraries  that  we  will  synthesize  and  qualify.  Each
collaborator  has  agreed  to  pay us a per-compound fee for compounds delivered
meeting certain agreed-upon acceptance criteria. Each party also paid an upfront
technology  access  fee  that  is  creditable  towards  the  future  purchase of
compounds.  Revenue  recognition  of upfront fees has been deferred, and revenue
under  these  collaboration  agreements will generally be recorded upon delivery
and  acceptance  of  compounds.  Each  party retains rights to use the compounds
developed  and  delivered  in its own proprietary drug discovery programs and in
its  collaborative  efforts  with  third  parties.

     Biotech  Collaborations

We  enjoy  collaborations  with  leading  biotechnology  product  developers and
solutions  providers,  among them Affymetrix, GeneMachines, AVI BioPharma, Inc.,
Silicon  Genetics,  Galapagos  NV,  Genomics Collaborative Inc., Accelrys, Inc.,
Akceli,  Inc.,  Ardais  Corp.,  Cogen  BioCognetics,  Inc.,  Impath  Predictive
Oncology,  Inc.  and  Virtual  Arrays,  Inc.  These  relationships  enable us to
continuously  update  and  enhance our technology base at a minimal cost, and at
the  same  time  facilitate  our  research  and  development  efforts.

     Academic  and  Government  Collaborations

In  order to enhance our research and technology access, we have established key
relationships  with  government  agencies and major academic centers in the U.S.
and  Europe. Our government collaborators include a number of U.S. Department of
Agriculture  campuses,  and  we  maintain  over ten academic collaborations with
investigators at such institutions as: Children's Hospital, Boston; Institute of
Molecular  and  Cellular  Biology,  CNRS,  Strasbourg,  France; Middle Tennessee
Research  Institute;  Stanford  University;  University  of  British  Columbia;
University  of California, San Francisco; and University of Georgia. The purpose
of  these  government and academic collaborations is to continuously improve our
core  technology  and to facilitate the establishment of new discovery programs.

We will continue to pursue strategic collaborations with government agencies and
academic  centers.  We  will  seek  to  retain significant rights to develop and
market  products  arising  from  our  strategic  alliances. In addition, we will
continue  to  invest  our  own  funds  in  certain  specific  areas  and product
opportunities  with  the  aim  of  maintaining, enhancing and extending our core
technology,  as well as increasing our opportunities to generate greater revenue
from  such  activities.

Acquisitions

We  have  used acquisitions to strategically position and advance our leadership
as  a  genomics-based  drug  discovery company. In May 2001, we acquired Artemis
Pharmaceuticals GmbH, a privately-held genetics and functional genomics company,
in  a stock-for-stock transaction valued at approximately $28.2 million. Located
in Koln and Tubingen, Germany, Artemis is focused on the use of vertebrate model
genetic  systems  such  as mice and zebrafish as tools for target identification
and  validation.

In  December  2001,  we  acquired  Genomica  Corporation,  a  publicly-traded
bioinformatics  company,  in  a  stock-for-stock  transaction  valued  at $110.0
million. The transaction was structured as a tender offer for 100% of Genomica's
outstanding  common  stock  and  was  followed  by  a  merger of Genomica with a
wholly-owned  subsidiary  of Exelixis. The exchange offer was closed on December
28,  2001,  and  the  subsequent  merger  completing the transaction occurred on
January  8,  2002.  Genomica  had  cash  and investments of approximately $109.6
million, which enhanced our ability to move our drug discovery programs forward.

Competition

We  face  intense  competition in the different market segments we are pursuing.
There  are many companies that have or are developing capabilities in the use of
model  systems  to  identify new products. In addition, there are many companies
focused  on  the  development  of  small molecule pharmaceuticals. Many genomics
companies  are  expanding  their capabilities, using a variety of techniques, to
determine  gene  function  and  to  develop products based on gene function. Our
potential  competitors  in  the  field  are  many  in  number  and include major
pharmaceutical  and  agricultural  companies,  diagnostic companies, specialized
biotechnology  companies,  genomics  companies  and  academic  institutions  and
universities.

Many  of  our potential competitors have significantly more financial, technical
and  other  resources  than  we  do,  which may allow them to have a competitive
advantage.  We  are  aware  that  companies  focused specifically on other model
systems  such as mice and yeast have alternative methods for identifying product
targets.  In  addition, pharmaceutical, biotechnology and genomics companies and
academic  institutions  are  conducting  work  in  this field. In the future, we
expect  the  field  to  become  more  competitive  with  companies  and academic
institutions  seeking  to  develop  competing  technologies.

Any  products  that  we  may  develop  or  discover  through  application of our
technologies  will  compete in highly competitive markets. Many of our potential
competitors in these markets have substantially greater financial, technical and
personnel  resources than we do, and they may succeed in developing technologies
and  products  that  may  render  our technologies and products and those of our
collaborators  obsolete  or noncompetitive. In addition, many of our competitors
have  significantly  greater  experience  than we do in their respective fields.

Research  and  Development  Expenses

Research  and  development  expenses  consist  primarily  of  salaries and other
personnel-related  expenses,  facilities  costs,  supplies,  licenses  and
depreciation  of  facilities  and laboratory equipment. Research and development
expenses  were  $112.0 million for the year ended December 31, 2002, compared to
$82.7  million  for  2001  and  $51.7  million  for  2000.

Proprietary  Rights

We seek patent protection in the United States and international markets for the
plant and animal genes and gene functions, proteins, antibodies, biotherapeutics
and small molecule pharmaceutical and agricultural products that we discover, as
well  as genetic methods and technology improvements for discovering such genes,
functions,  proteins,  antibodies,  biotherapeutics  and  small  molecule
pharmaceutical  and agricultural products. Our intellectual property strategy is
designed  to provide us with freedom to operate and facilitate commercialization
of  our current and future products. Our patent portfolio includes a total of 47
issued  U.S.  patents.  Our  p-element  patent,  U.S.  patent  no.  4,670,388,
exclusively  licensed  from Carnegie Institution of Washington, has the earliest
patent  expiration date, which is June 2, 2004. We are the assignee or exclusive
licensee  of  four  allowed  and  209  pending  U.S.  patent  applications  and
corresponding  international  or  foreign  patent  applications  related  to our
genetic  and  comparative  genomic  technologies,  gene  and protein targets and
specialized  screens,  and  the  application  of  these  technologies to diverse
industries  including  agriculture,  pharmaceuticals  and  diagnostics.  One
additional  U.S.  patent  has  been issued, one U.S. patent application has been
allowed  and  44  U.S. patent applications are pending as part of the Agrinomics
joint  venture with Bayer CropScience. An additional 11 U.S. patent applications
are  pending  as  part  of  the  Genoptera  joint  venture  with  Bayer.

We also rely in part on trade secret protection of our intellectual property. We
try  to  protect  our  trade secrets by entering into confidentiality agreements
with  third  parties,  employees  and consultants. Our employees and consultants
also sign agreements requiring that they assign to us their interests in patents
and  other  intellectual  property arising from their work for us. All employees
sign an agreement not to engage in any conflicting employment or activity during
their  employment  with  us  and  not  to  disclose  or  misuse our confidential
information.  However,  it  is possible that these agreements may be breached or
invalidated,  and  if  so,  there  may  not  be  an  adequate  corrective remedy
available.  Accordingly,  we  cannot ensure that employees, consultants or third
parties  will  not  breach  the  confidentiality  provisions in our contracts or
infringe  or  misappropriate  our  patents,  trade secrets and other proprietary
rights, or that measures we are taking to protect our proprietary rights will be
adequate.

In  the future, third parties may file claims asserting that our technologies or
products  infringe  on  their  intellectual property.  We cannot predict whether
third  parties  will  assert  such claims against us or against the licensors of
technology licensed to us, or whether those claims will harm our business. If we
are  forced  to  defend  ourselves against such claims, whether they are with or
without  merit  and  whether  they  are  resolved  in  favor of, or against, our
licensors or us, we may face costly litigation and the diversion of management's
attention  and  resources.  As a result of such disputes, we may have to develop
costly  non-infringing  technology  or  enter  into  licensing agreements. These
agreements,  if  necessary,  may be unavailable on terms acceptable to us, or at
all,  which  could  seriously  harm  our  business  or  financial  condition.

Employees

As  of  December 31, 2002, we had 550 full-time employees worldwide, 220 of whom
hold  Ph.D.  and/or  M.D.  degrees  and  476  of  whom were engaged in full-time
research and development activities. In 2002, we added several senior executives
to  our  management  team.  We  plan  to  expand  our  preclinical  and clinical
development  programs,  as  well as our corporate development programs, and hire
additional  staff  as corporate collaborations are established and we expand our
internal  development  efforts  to  include  clinical programs. Our success will
depend  upon our ability to attract and retain employees. We face competition in
this  regard  from other companies in the biotechnology, pharmaceutical and high
technology industries as well as research and academic institutions. None of our
employees  are  represented  by  a  labor  union,  and  we consider our employee
relations  to  be  good.

Risk  Factors

EXELIXIS HAS A HISTORY OF NET LOSSES. WE EXPECT TO CONTINUE TO INCUR NET LOSSES,
AND  WE  MAY  NOT  ACHIEVE  OR  MAINTAIN  PROFITABILITY.

We  have incurred net losses each year since our inception, including a net loss
of  approximately $86.1 million for the year ended December 31, 2002. As of that
date,  we  had an accumulated deficit of approximately $287.4 million. We expect
these  losses  to  continue  and anticipate negative operating cash flow for the
foreseeable  future.  The  size of these net losses will depend, in part, on the
rate of growth, if any, in our license and contract revenues and on the level of
our  expenses.  Our  research  and  development  expenditures  and  general  and
administrative  costs have exceeded our revenues to date, and we expect to spend
significant  additional  amounts  to  fund  research and development in order to
enhance  our  core  technologies  and undertake product development. In 2001, we
acquired  a  rebeccamycin  analogue that is in Phase II clinical development. We
anticipate initiating next development steps, if any, following discussions with
the FDA. Drug substance to be used in Company-sponsored clinical trials has been
manufactured  in  bulk supply by third-party suppliers. In addition, we are also
preparing  to  file  our  first  IND for a proprietary compound. As a result, we
expect that our operating expenses will increase significantly in the near term,
and  consequently,  we  will need to generate significant additional revenues to
achieve  profitability.  Even  if  we  do  increase  our  revenues  and  achieve
profitability,  we  may  not  be  able  to  sustain  or  increase profitability.

WE WILL NEED ADDITIONAL CAPITAL IN THE FUTURE, WHICH MAY NOT BE AVAILABLE TO US.

Our  future  capital  requirements  will  be substantial and will depend on many
factors,  including:

     -    payments  received  under  collaborative  agreements;
     -    the  progress  and scope of our collaborative and independent research
          and  development  projects;
     -    our  need to expand our product development efforts as well as develop
          manufacturing  and  marketing  capabilities to commercialize products;
     -    the  filing,  prosecution  and  enforcement  of  patent  claims;  and
     -    increased  costs  for  clinical  activities.

We anticipate that our current cash and cash equivalents, short-term investments
and  funding  to  be  received from collaborators will enable us to maintain our
currently  planned  operations  for  at least the next two years. Changes to our
current  operating  plan  may  require us to consume available capital resources
significantly  sooner  than  we  expect.  We  may  be unable to raise sufficient
additional capital when we need it, on favorable terms or at all. If our capital
resources  are insufficient to meet future capital requirements, we will have to
raise additional funds. The sale of equity or convertible debt securities in the
future  may be dilutive to our stockholders, and debt financing arrangements may
require us to pledge certain assets and enter into covenants that would restrict
our  ability  to incur further indebtedness. If we are unable to obtain adequate
funds  on  reasonable  terms,  we  may  be  required  to  curtail  operations
significantly  or  to  obtain  funds  by  entering  into  financing,  supply  or
collaboration  agreements  on  unattractive  terms.

DIFFICULTIES WE MAY ENCOUNTER MANAGING OUR GROWTH MAY DIVERT RESOURCES AND LIMIT
OUR  ABILITY  TO  SUCCESSFULLY  EXPAND  OUR  OPERATIONS.

We  have  experienced  a period of rapid and substantial growth that has placed,
and our anticipated growth in the future will continue to place, a strain on our
research,  administrative  and  operational  infrastructure.  As  our operations
expand  domestically  and  internationally,  we  will need to continue to manage
multiple  locations  and  additional  relationships  with  various collaborative
partners,  suppliers  and  other  third  parties.  Our  ability  to  manage  our
operations  and  growth  effectively  requires  us  to  continue  to improve our
operational,  financial  and  management  controls,  reporting  systems  and
procedures.  We  may  not  be able to successfully implement improvements to our
management  information and control systems in an efficient or timely manner and
may  discover  deficiencies  in  existing  systems  and  controls.  In addition,
acquisitions  involve  the  integration  of  different  financial and management
reporting  systems.  We  may  not  be  able  to  successfully  integrate  the
administrative  and  operational  infrastructure  without significant additional
improvements  and  investments  in  management  systems  and  procedures.

WE ARE DEPENDENT ON OUR COLLABORATIONS WITH MAJOR COMPANIES. IF WE ARE UNABLE TO
ACHIEVE  MILESTONES, DEVELOP PRODUCTS OR RENEW OR ENTER INTO NEW COLLABORATIONS,
OUR  REVENUES MAY DECREASE AND OUR ACTIVITIES MAY FAIL TO LEAD TO COMMERCIALIZED
PRODUCTS.

Substantially  all  of our revenues to date have been derived from collaborative
research  and  development  agreements.  Revenues  from research and development
collaborations  depend  upon continuation of the collaborations, the achievement
of  milestones  and  royalties  derived  from 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  such  collaborative  agreements.  In  addition, some of our
collaborations  are  exclusive  and  preclude  us  from entering into additional
collaborative  arrangements  with  other  parties  in  the  area  or  field  of
exclusivity.

We  currently  have  collaborative research agreements with Bayer, Bristol-Myers
Squibb  (two  agreements),  SmithKlineBeecham,  Protein  Design  Labs,  Dow
AgroSciences,  Renessen  and  Bayer  CropScience.  Our  current  collaborative
agreement  with  Bayer  is  scheduled  to  expire  in  2008, after which it will
automatically  be  extended for one-year terms unless terminated by either party
upon  12-months  written  notice.  Our  agreement permits Bayer to terminate our
collaborative  activities  prior  to  2008  upon  the  occurrence  of  specified
conditions,  such as the failure to agree on key strategic issues after a period
of  years or the acquisition of Exelixis by certain specified third parties. Our
agreement with Bayer is subject to termination at an earlier date if two or more
of  our  Chief  Executive  Officer,  Chief  Scientific  Officer,  Agricultural
Biotechnology  Program  Leader  and  Chief  Informatics  Officer cease to have a
relationship  with  us  within  nine months of each other. Our MOA collaborative
agreement  with  Bristol-Myers  Squibb  expires  in  September  2004. Our cancer
collaborative  agreement  with  Bristol-Myers  Squibb  expires in July 2004. Our
recent  alliance  with SmithKlineBeecham is scheduled to expire in October 2008,
but  is  subject  to  earlier termination at the discretion of SmithKlineBeecham
starting  in  2005  if  Exelixis  fails  to  meet certain diligence obligations.
Research funding under our collaborative agreement with Protein Design Labs will
expire  in  June  2003.  Similarly,  funding  under  our  arrangement  with  Dow
AgroSciences  is  scheduled to expire in July 2003, after which Dow AgroSciences
has  the  option  to  renew  on  an  annual  basis.  Our  collaborative research
arrangement with Bayer CropScience is scheduled to expire in September 2004. The
Bayer  CropScience arrangement is conducted through a limited liability company,
Agrinomics,  which  is  owned  equally  by Bayer CropScience and Exelixis. Bayer
CropScience  may  surrender its interest in Agrinomics and terminate the related
research collaboration prior to the scheduled expiration upon the payment of the
subsequent  year's  funding  commitment.  Agrinomics  is  party  to  a  recent
collaborative  agreement  with  Renessen,  which expires in December 2005 but is
subject  to  earlier  termination at the discretion of Renessen prior to October
2003.

If  these  existing agreements are not renewed or if we are unable to enter into
new  collaborative agreements on commercially acceptable terms, our revenues and
product  development  efforts  may  be  adversely  affected.  For  example,  our
agreement  with  Pharmacia  terminated  by  mutual  agreement  in February 2002,
eliminated the opportunity for us to earn approximately $9.0 million in research
revenue  in  each  of the next two years. Although we expect to enter into other
collaborations that may offset this loss of revenue, we may not be able to enter
into  a  new collaborative agreement on similar or superior financial terms than
those  under  the  Pharmacia  arrangement,  and  the timing of new collaborative
agreements  may  have  a  significant  effect  on  our  ability  to  continue to
successfully  meet  our  corporate  goals  and  milestones.

CONFLICTS  WITH  OUR  COLLABORATORS  COULD  JEOPARDIZE  THE  OUTCOME  OF  OUR
COLLABORATIVE  AGREEMENTS  AND  OUR  ABILITY  TO  COMMERCIALIZE  PRODUCTS.

We  are  conducting  proprietary  research  programs  in  specific  disease  and
agricultural product areas that are not covered by our collaborative agreements.
Our  pursuit  of opportunities in agricultural and pharmaceutical markets could,
however, result in conflicts with our collaborators in the event that any of our
collaborators  take the position that our internal activities overlap with those
areas  that  are  exclusive  to  our  collaborative agreements, and we should be
precluded  from  such  internal  activities.  Moreover,  disagreements  with our
collaborators  could  develop  over  rights  to  our  intellectual  property. In
addition,  our  collaborative  agreements  may have provisions that give rise to
disputes  regarding  the  rights  and  obligations of the parties, including the
rights  of  collaborators with respect to our internal programs and disease area
research.  Any  conflict  with  or  among  our  collaborators  could lead to the
termination  of  our  collaborative  agreements, delay collaborative activities,
reduce our ability to renew agreements or obtain future collaboration agreements
or  result  in  litigation  or  arbitration  and  would  negatively  impact  our
relationship  with  existing  collaborators.

We  have  limited  or  no  control over the resources that our collaborators may
choose to devote to our joint efforts. Our collaborators may breach or terminate
their  agreements  with  us  or  fail  to  perform their obligations thereunder.
Further,  our collaborators may elect not to develop products arising out of our
collaborative  arrangements  or  may  fail to devote sufficient resources to the
development,  manufacture,  marketing  or  sale of such products. Certain of our
collaborators  could  also  become  our  competitors  in  the  future.  If  our
collaborators  develop  competing  products,  preclude  us  from  entering  into
collaborations  with  their  competitors,  fail  to  obtain necessary regulatory
approvals,  terminate  their  agreements  with  us prematurely or fail to devote
sufficient  resources  to the development and commercialization of our products,
our  product  development  efforts  could  be  delayed  and  may fail to lead to
commercialized  products.

OUR  POTENTIAL  THERAPEUTIC  PRODUCTS  ARE  SUBJECT  TO  A LENGTHY AND UNCERTAIN
REGULATORY  PROCESS  THAT  MAY NOT RESULT IN THE NECESSARY REGULATORY APPROVALS,
WHICH  COULD  ADVERSELY  AFFECT  OUR  ABILITY  TO  COMMERCIALIZE  PRODUCTS.

The U.S. Food and Drug Administration, or FDA, must approve any drug or biologic
product  before  it can be marketed in the U.S.  Any products resulting from our
research  and  development  efforts  must  also  be  approved  by the regulatory
agencies  of  foreign  governments before the product can be sold outside of the
U.S. Before a new drug application or biologics license application can be filed
with  the  FDA,  the  product  candidate must undergo extensive clinical trials,
which  can  take  many  years  and  may  require  substantial  expenditures. The
regulatory  process  also  requires  preclinical  testing.  Data  obtained  from
preclinical  and clinical activities are susceptible to varying interpretations,
which could delay, limit or prevent regulatory approval.  In addition, delays or
rejections  may  be  encountered  based  upon  changes  in regulatory policy for
product  approval during the period of product development and regulatory agency
review.  Completion  of  clinical trials may take several years or more, but the
length of time generally varies substantially according to the type, complexity,
novelty  and  intended  use  of  a  product candidate.  We estimate that typical
clinical  trials  are  completed  over  the  following  timelines:



             
               CLINICAL PHASE    ESTIMATED COMPLETION PERIOD
               --------------    ---------------------------

               Phase I                               1 Year
               Phase II                           1-2 Years
               Phase III                          2-4 Years



However,  the  duration  and  the cost of clinical trials may vary significantly
over  the  life  of  a  project  as  a  result of differences arising during the
clinical  trial  protocol,  including,  among  others,  the  following:

     -    the  number  of  patients  that  ultimately  participate in the trial;
     -    the  duration  of  patient follow-up that seems appropriate in view of
          the  results;
     -    the  number  of  clinical  sites  included  in  the  trials;  and
     -    the  length  of  time  required  to  enroll suitable patient subjects.

Any  clinical trial may fail to produce results satisfactory to the FDA. The FDA
could  determine  that  the  design of a clinical trial is inadequate to produce
reliable  results.  Negative  or  inconclusive results or adverse medical events
during  a  clinical  trial  could  cause  a  clinical  trial  to  be repeated or
development  of  a  product  or  clinical  trial  to be terminated. The clinical
development and regulatory approval process is expensive and time consuming. Any
failure  to  obtain  regulatory  approval  could  delay  or  prevent  us  from
commercializing  products.

Our  efforts  to  date  have  been  primarily limited to identifying targets and
developing  small molecule compounds against those targets. Significant research
and  development  efforts  will be necessary before any of our products directed
against such targets can be commercialized. If regulatory approval is granted to
any of our products, the approval may impose limitations on the uses for which a
product  may  be  marketed.  Further, even if regulatory approval is obtained, a
marketed  product  and  its  manufacturer  are  subject to continual review, and
discovery  of  previously  unknown  problems  with a product or manufacturer may
result  in  restrictions and sanctions with respect to the product, manufacturer
and  relevant  manufacturing  facility, including withdrawal of the product from
the  market.

CLINICAL  TESTING  OF  OUR POTENTIAL PRODUCTS MAY FAIL TO DEMONSTRATE SAFETY AND
EFFICACY,  WHICH  COULD  PREVENT  OR  SIGNIFICANTLY  DELAY  REGULATORY APPROVAL.

Clinical  trials are inherently risky and may reveal that our potential products
are  ineffective  or  have  unacceptable toxicity or other side effects that may
significantly  limit  the  possibility  of  regulatory approval of the potential
product.  The  regulatory review and approval process is extensive and uncertain
and  typically  takes  many  years  to  complete. The FDA requires submission of
extensive  preclinical,  clinical and manufacturing data for each indication for
which  approval  is  sought  in  order  to assess the safety and efficacy of the
potential  product.  In  addition,  the  results  of  preliminary studies do not
necessarily  predict  clinical  or  commercial  success,  and larger later-stage
clinical  trials  may  fail  to  confirm the results observed in the preliminary
studies.  With  respect to our own proprietary compounds in development, we have
established  timelines  for  manufacturing  and  clinical  development  based on
existing  knowledge  of  the  compound  and  industry  metrics.  We have limited
experience in conducting clinical studies and may not be able to assure that any
specified  timelines  with  respect  to the initiation or completion of clinical
studies  may  be  achieved.

In  July 2001, we acquired a cancer compound, a rebeccamycin analogue, currently
in  Phase  II  clinical studies. This compound was manufactured by Bristol-Myers
Squibb,  and  clinical trials to date have been conducted by the National Cancer
Institute,  or NCI. We will have to conduct additional clinical testing in order
to meet FDA requirements for regulatory approval. We have no prior experience in
conducting  clinical  trials,  and,  in  conjunction  with the NCI, we expect to
undertake  further  clinical  development  of this compound under our own IND in
order  to  obtain  regulatory  approval.  We  may  not  be  able  to  rapidly or
effectively  assume  responsibility for further development of this compound. We
do  not  know  whether  planned  clinical  trials  will  begin  on time, will be
completed  on  schedule,  or at all, will be sufficient for registration or will
result in approvable products. Our product development costs will increase if we
have  delays  in  testing  or  approvals or if we need to perform more or larger
clinical  trials  than  planned.  If  the  delays are significant, our financial
results  and  the  commercial prospects for our products will be harmed, and our
ability  to  become  profitable  will  be  delayed.

WE  LACK  THE  CAPABILITY  TO MANUFACTURE COMPOUNDS FOR CLINICAL TRIALS AND WILL
RELY  ON  THIRD  PARTIES  TO  MANUFACTURE  OUR POTENTIAL PRODUCTS, AND WE MAY BE
UNABLE  TO  OBTAIN  REQUIRED  MATERIAL  IN A TIMELY MANNER OR AT A QUALITY LEVEL
REQUIRED  TO  RECEIVE  REGULATORY  APPROVAL.

We  currently  do not have manufacturing capabilities or experience necessary to
produce  materials  for  clinical  trials,  including  for our Phase II clinical
compound,  a  rebeccamycin  analogue.  We  intend  to  rely on collaborators and
third-party  contractors  to  produce  materials  necessary  for preclinical and
clinical testing. We will rely on selected manufacturers to deliver materials on
a  timely basis and to comply with applicable regulatory requirements, including
the  FDA's current Good Manufacturing Practices, or GMP. These manufacturers may
not be able to produce material on a timely basis or manufacture material at the
quality  level or in the quantity required to meet our development timelines and
applicable  regulatory requirements. If we are unable to contract for production
of sufficient quantity and quality of materials on acceptable terms, our planned
clinical  trials may be delayed. Delays in preclinical or clinical testing could
delay  the filing of our INDs and the initiation of clinical trials that we have
currently  planned.  In  addition,  our  outsourcing  efforts  with  respect  to
manufacturing  clinical supplies will result in a dependence on our suppliers to
timely manufacture and deliver sufficient quantities of materials produced under
GMP  conditions to enable us to conduct planned clinical trials, and if possible
to  bring  products  to  market  in  a  timely  manner.

WE  HAVE  NO  EXPERIENCE IN DEVELOPING, MANUFACTURING AND MARKETING PRODUCTS AND
MAY  BE  UNABLE  TO  COMMERCIALIZE  PROPRIETARY  PRODUCTS.

Initially,  we relied on our collaborators to develop and commercialize products
based  on our research and development efforts. We have limited or no experience
in  using  the targets that we identify to develop our own proprietary products,
or developing small molecule compounds against those targets. Our recent efforts
in  applying  our  drug  development  capabilities to our proprietary targets in
cancer  are  subject  to  significant  risk  and  uncertainty, particularly with
respect  to  our  ability  to  meet  currently estimated timelines and goals for
completing  preclinical  development  efforts  and  filing  an IND for compounds
developed.  In  order  for  us  to  commercialize  products,  we  would  need to
significantly  enhance  our capabilities with respect to product development and
establish  manufacturing  and marketing capabilities, either directly or through
outsourcing  or  licensing  arrangements.  We may not be able to enter into such
outsourcing or licensing agreements on commercially reasonable terms, or at all.

SINCE  OUR  TECHNOLOGIES  HAVE  MANY  POTENTIAL APPLICATIONS AND WE HAVE LIMITED
RESOURCES,  OUR  FOCUS  ON  A  PARTICULAR  AREA  MAY  RESULT  IN  OUR FAILURE TO
CAPITALIZE  ON  MORE  PROFITABLE  AREAS.

We have limited financial and managerial resources. This requires us to focus on
product  candidates  in specific industries and forego opportunities with regard
to  other  products  and  industries.  For  example, depending on our ability to
allocate  resources,  a  decision  to  concentrate  on a particular agricultural
program  may  mean  that  we will not have resources available to apply the same
technology  to a pharmaceutical project. While our technologies may permit us to
work  in  both  areas,  resource commitments may require trade-offs resulting in
delays in the development of certain programs or research areas, which may place
us  at  a  competitive disadvantage. Our decisions impacting resource allocation
may  not  lead  to  the development of viable commercial products and may divert
resources  from  more  profitable  market  opportunities.

OUR COMPETITORS MAY DEVELOP PRODUCTS AND TECHNOLOGIES THAT MAKE OUR PRODUCTS AND
TECHNOLOGIES  OBSOLETE.

The  biotechnology  industry  is highly fragmented and is characterized by rapid
technological  change.  In  particular,  the  area of gene research is a rapidly
evolving  field.  We  face,  and will continue to face, intense competition from
large  biotechnology  and pharmaceutical companies, as well as academic research
institutions,  clinical  reference laboratories and government agencies that are
pursuing  research  activities  similar  to  ours.  Some of our competitors have
entered  into  collaborations  with leading companies within our target markets,
including  some of our existing collaborators. Our future success will depend on
our  ability  to  maintain  a competitive position with respect to technological
advances.

Any  products that are developed through our technologies will compete in highly
competitive  markets.  Further,  our  competitors may be more effective at using
their  technologies  to  develop  commercial products. Many of the organizations
competing  with  us  have  greater  capital  resources,  larger  research  and
development  staffs  and  facilities,  more  experience  in obtaining regulatory
approvals  and  more extensive product manufacturing and marketing capabilities.
As a result, our competitors may be able to more easily develop technologies and
products  that  would  render  our  technologies  and products, and those of our
collaborators,  obsolete  and  noncompetitive.

IF  WE ARE UNABLE TO ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY, THIRD PARTIES
MAY  BE  ABLE TO USE OUR TECHNOLOGY, WHICH COULD ADVERSELY AFFECT OUR ABILITY TO
COMPETE  IN  THE  MARKET.

Our  success  will  depend in part on our ability to obtain patents and maintain
adequate protection of the intellectual property related to our technologies and
products.  The patent positions of biotechnology companies, including our patent
position,  are  generally  uncertain  and  involve  complex  legal  and  factual
questions.  We  will  be  able  to protect our intellectual property rights from
unauthorized  use  by third parties only to the extent that our technologies are
covered  by valid and enforceable patents or are effectively maintained as trade
secrets. The laws of some foreign countries do not protect intellectual property
rights  to  the  same  extent  as  the laws of the U.S., and many companies have
encountered  significant  problems  in  protecting  and defending such rights in
foreign  jurisdictions.  We  will  continue  to  apply  for patents covering our
technologies  and  products  as  and  when  we  deem appropriate. However, these
applications  may  be  challenged  or  may fail to result in issued patents. Our
existing  patents and any future patents we obtain may not be sufficiently broad
to  prevent others from practicing our technologies or from developing competing
products.  Furthermore,  others may independently develop similar or alternative
technologies  or  design  around  our  patents.  In addition, our patents may be
challenged,  invalidated  or fail to provide us with any competitive advantages.

We  rely  on  trade  secret  protection  for  our  confidential  and proprietary
information.  We  have  taken  security  measures  to  protect  our  proprietary
information  and  trade  secrets,  but  these  measures may not provide adequate
protection.  While  we  seek  to protect our proprietary information by entering
into  confidentiality  agreements with employees, collaborators and consultants,
we  cannot assure you that our proprietary information will not be disclosed, or
that we can meaningfully protect our trade secrets. In addition, our competitors
may  independently  develop  substantially equivalent proprietary information or
may  otherwise  gain  access  to  our  trade  secrets.

LITIGATION  OR  THIRD-PARTY  CLAIMS  OF INTELLECTUAL PROPERTY INFRINGEMENT COULD
REQUIRE  US TO SPEND SUBSTANTIAL TIME AND MONEY AND ADVERSELY AFFECT OUR ABILITY
TO  DEVELOP  AND  COMMERCIALIZE  PRODUCTS.

Our  commercial  success  depends  in  part  on  our ability to avoid infringing
patents  and  proprietary rights of third parties and not breaching any licenses
that  we  have  entered into with regard to our technologies. Other parties have
filed,  and in the future are likely to file, patent applications covering genes
and  gene  fragments, techniques and methodologies relating to model systems and
products  and  technologies  that  we  have  developed  or intend to develop. If
patents  covering  technologies required by our operations are issued to others,
we  may  have to rely on licenses from third parties, which may not be available
on  commercially  reasonable  terms,  or  at  all.

Third  parties  may  accuse us of employing their proprietary technology without
authorization.  In addition, third parties may obtain patents that relate to our
technologies  and  claim  that use of such technologies infringes these patents.
Regardless  of  their  merit,  such claims could require us to incur substantial
costs,  including  the  diversion  of  management  and  technical  personnel, in
defending  ourselves  against  any  such claims or enforcing our patents. In the
event  that  a successful claim of infringement is brought against us, we may be
required  to  pay damages and obtain one or more licenses from third parties. We
may  not  be  able  to  obtain  these  licenses at a reasonable cost, or at all.
Defense  of  any  lawsuit  or  failure  to  obtain  any  of these licenses could
adversely  affect  our  ability  to  develop  and  commercialize  products.

THE  LOSS  OF  KEY  PERSONNEL  OR THE INABILITY TO ATTRACT AND RETAIN ADDITIONAL
PERSONNEL  COULD  IMPAIR  OUR  ABILITY  TO  EXPAND  OUR  OPERATIONS.

We  are  highly  dependent  on  the  principal  members  of  our  management and
scientific  staff,  the  loss  of  whose  services  might  adversely  impact the
achievement  of  our objectives and the continuation of existing collaborations.
In  addition,  recruiting  and  retaining  qualified  scientific  and  clinical
personnel  to  perform  future research and development work will be critical to
our  success.  We  do  not  currently  have  sufficient executive management and
technical  personnel  to  fully  execute our business plan. There is currently a
shortage  of skilled executives and employees with technical expertise, and this
shortage  is  likely to continue. As a result, competition for skilled personnel
is  intense,  and  turnover  rates  are  high.  Although  we  believe we will be
successful  in  attracting  and  retaining  qualified personnel, competition for
experienced  scientists  from numerous companies and academic and other research
institutions  may  limit  our  ability  to  do  so.

Our business operations will require additional expertise in specific industries
and  areas  applicable  to  products  identified  and  developed  through  our
technologies.  These  activities  will  require  the  addition of new personnel,
including  management  and technical personnel and the development of additional
expertise  by  existing employees. The inability to attract such personnel or to
develop  this  expertise  could  prevent  us  from expanding our operations in a
timely  manner,  or  at  all.

OUR  COLLABORATIONS  WITH  OUTSIDE  SCIENTISTS MAY BE SUBJECT TO RESTRICTION AND
CHANGE.

We  work with scientific and clinical advisors and collaborators at academic and
other institutions that assist us in our research and development efforts. These
scientists  and  advisors  are  not our employees and may have other commitments
that  would  limit  their  availability  to  us.  Although  our  advisors  and
collaborators  generally  agree  not  to  do  competing  work,  if a conflict of
interest  between their work for us and their work for another entity arises, we
may  lose  their  services. In addition, although our advisors and collaborators
sign  agreements  not  to  disclose our confidential information, it is possible
that  valuable  proprietary  knowledge  may  become publicly known through them.

SOCIAL  ISSUES  MAY  LIMIT  THE  PUBLIC  ACCEPTANCE  OF  GENETICALLY  ENGINEERED
PRODUCTS,  WHICH  COULD  REDUCE  DEMAND  FOR  OUR  PRODUCTS.

Although  our  technology  is  not  dependent  on  genetic  engineering, genetic
engineering  plays  a prominent role in our approach to product development. For
example,  research efforts focusing on plant traits may involve either selective
breeding  or  modification  of  existing  genes in the plant under study. Public
attitudes  may  be influenced by claims that genetically engineered products are
unsafe  for  consumption  or  pose  a danger to the environment. Such claims may
prevent  our genetically engineered products from gaining public acceptance. The
commercial  success  of  our  future  products  will  depend, in part, on public
acceptance  of  the  use of genetically engineered products, including drugs and
plant  and  animal  products.

The  subject  of genetically modified organisms has received negative publicity,
which  has  aroused  public debate. For example, certain countries in Europe are
considering  regulations  that  may  ban products or require express labeling of
products  that  contain  genetic  modifications  or  are "genetically modified."
Adverse  publicity  has resulted in greater regulation internationally and trade
restrictions  on  imports  of genetically altered products. If similar action is
taken in the U.S., genetic research and genetically engineered products could be
subject  to  greater  domestic  regulation,  including  stricter  labeling
requirements.  To  date, our business has not been hampered by these activities.
However,  such  publicity  in the future may prevent any products resulting from
our  research from gaining market acceptance and reduce demand for our products.

LAWS  AND  REGULATIONS  MAY  REDUCE  OUR  ABILITY TO SELL GENETICALLY ENGINEERED
PRODUCTS  THAT  WE  OR  OUR  COLLABORATORS  DEVELOP  IN  THE  FUTURE.

We  or  our  collaborators  may  develop genetically engineered agricultural and
animal  products.  The  field-testing,  production  and marketing of genetically
engineered  products  are  subject  to  regulation  by federal, state, local and
foreign  governments.  Regulatory  agencies  administering  existing  or  future
regulations  or  legislation  may  prevent  us  from  producing  and  marketing
genetically  engineered  products  in  a  timely  manner or under technically or
commercially  feasible  conditions.  In  addition,  regulatory action or private
litigation  could result in expenses, delays or other impediments to our product
development programs and the commercialization of products. The FDA has released
a  policy  statement stating that it will apply the same regulatory standards to
foods  developed  through  genetic  engineering as it applies to foods developed
through traditional plant breeding. Genetically engineered food products will be
subject  to  premarket review, however, if these products raise safety questions
or  are  deemed to be food additives. Our products may be subject to lengthy FDA
reviews  and  unfavorable  FDA  determinations if they raise questions regarding
safety  or  our  products  are  deemed  to  be  food  additives.

The  FDA  has  also  announced  that  it will not require genetically engineered
agricultural products to be labeled as such, provided that these products are as
safe  and  have the same nutritional characteristics as conventionally developed
products.  The  FDA  may  reconsider  or change its policies, and local or state
authorities  may  enact  labeling  requirements,  either  of  which could have a
material  adverse  effect  on our ability or the ability of our collaborators to
develop  and  market  products  resulting  from  our  efforts.

WE  USE  HAZARDOUS  CHEMICALS  AND  RADIOACTIVE  AND BIOLOGICAL MATERIALS IN OUR
BUSINESS. ANY CLAIMS RELATING TO IMPROPER HANDLING, STORAGE OR DISPOSAL OF THESE
MATERIALS  COULD  BE  TIME  CONSUMING  AND  COSTLY.

Our  research  and development processes involve the controlled use of hazardous
materials,  including  chemicals  and  radioactive and biological materials. Our
operations  produce  hazardous  waste  products. We cannot eliminate the risk of
accidental  contamination  or  discharge  and  any  resultant  injury from these
materials.  Federal,  state  and  local  laws  and  regulations  govern the use,
manufacture,  storage,  handling  and disposal of hazardous materials. We may be
sued  for  any  injury  or contamination that results from our use or the use by
third  parties  of  these  materials, and our liability may exceed our insurance
coverage  and  our  total  assets.  Compliance  with  environmental  laws  and
regulations  may  be  expensive, and current or future environmental regulations
may  impair  our  research,  development  and  production  efforts.

In  addition,  our  collaborators may use hazardous materials in connection with
our  collaborative  efforts.  To  our  knowledge,  their  work  is  performed in
accordance  with  applicable biosafety regulations. In the event of a lawsuit or
investigation,  however,  we  could be held responsible for any injury caused to
persons  or  property  by  exposure to, or release of, these hazardous materials
used  by  these  parties.  Further,  we  may  be  required  to  indemnify  our
collaborators  against  all  damages  and  other  liabilities arising out of our
development  activities  or  products  produced  in  connection  with  these
collaborations.

WE  EXPECT  THAT  OUR  QUARTERLY  RESULTS OF OPERATIONS WILL FLUCTUATE, AND THIS
FLUCTUATION  COULD  CAUSE  OUR  STOCK PRICE TO DECLINE, CAUSING INVESTOR LOSSES.

Our  quarterly  operating  results have fluctuated in the past and are likely to
fluctuate  in  the future. A number of factors, many of which we cannot control,
could  subject  our  operating results and stock price to volatility, including:

     -    recognition  of  upfront  licensing  or  other  fees;
     -    payments of non-refundable upfront or licensing fees to third parties;
     -    acceptance  of  our  technologies  and  platforms;
     -    the  success  rate  of  our  discovery  efforts  leading  to milestone
          payments  and  royalties;
     -    the  introduction  of new technologies or products by our competitors;
     -    the  timing  and  willingness  of  collaborators  to commercialize our
          products;
     -    our  ability  to  enter  into  new  collaborative  relationships;
     -    the  termination  or  non-renewal  of  existing  collaborations;
     -    the  timing  and  amount of expenses incurred for clinical development
          and  manufacturing  of  our  products;
     -    the  impairment  of  acquired  goodwill  and  other  assets;  and
     -    general  and industry-specific economic conditions that may affect our
          collaborators'  research  and  development  expenditures

A  large  portion  of our expenses, including expenses for facilities, equipment
and  personnel,  are  relatively fixed in the short term. In addition, we expect
operating  expenses to increase significantly during the next year. Accordingly,
if  our  revenues decline or do not grow as anticipated due to the expiration of
existing contracts or our failure to obtain new contracts, our inability to meet
milestones  or  other  factors, we may not be able to correspondingly reduce our
operating  expenses.  Failure  to  achieve  anticipated levels of revenues could
therefore  significantly  harm  our  operating  results  for a particular fiscal
period.

Due  to the possibility of fluctuations in our revenues and expenses, we believe
that  quarter-to-quarter  comparisons  of  our  operating results are not a good
indication  of our future performance. As a result, in some future quarters, our
operating  results  may  not  meet the expectations of stock market analysts and
investors,  which  could  result  in  a  decline  in  the  price  of  our stock.

OUR  STOCK  PRICE  MAY  BE  EXTREMELY  VOLATILE.

We believe the trading price of our common stock will remain highly volatile and
may  fluctuate  substantially  due  to  factors  such  as  the  following:

     -    the announcement of new products or services by us or our competitors;
     -    the  failure  of  new  products  in  clinical  trials  by  us  or  our
          competitors;
     -    quarterly variations in our or our competitors' results of operations;
     -    failure to achieve operating results projected by securities analysts;
     -    changes  in  earnings  estimates  or  recommendations  by  securities
          analysts;
     -    developments  in  the  biotechnology  industry;
     -    acquisitions  of  other  companies  or  technologies;  and
     -    general  market  conditions  and  other  factors,  including  factors
          unrelated to our operating performance or the operating performance of
          our  competitors.

These  factors  and  fluctuations,  as  well  as general economic, political and
market  conditions,  may  materially  adversely  affect  the market price of our
common  stock.

In  the past, following periods of volatility in the market price of a company's
securities,  securities  class  action  litigation  has often been instituted. A
securities  class  action  suit against us could result in substantial costs and
divert  management's  attention  and  resources, which could have a material and
adverse  effect  on  our  business.

WE  ARE  EXPOSED  TO  RISKS  ASSOCIATED  WITH  ACQUISITIONS.

We  have  made,  and  may  in  the  future make, acquisitions of, or significant
investments  in,  businesses  with  complementary  products,  services  and/or
technologies.  Acquisitions  involve  numerous risks, including, but not limited
to:

     -    difficulties and increased costs in connection with integration of the
          personnel,  operations,  technologies  and  products  of  acquired
          companies;
     -    diversion  of  management's  attention from other operational matters;
     -    the  potential  loss  of  key  employees  of  acquired  companies;
     -    the  potential  loss  of  key collaborators of the acquired companies;
     -    lack  of  synergy,  or  the  inability  to realize expected synergies,
          resulting  from  the  acquisition;  and
     -    acquired  intangible  assets  becoming  impaired  as  a  result  of
          technological  advancements  or worse-than-expected performance of the
          acquired  company.

Mergers  and acquisitions are inherently risky, and the inability to effectively
manage these risks could materially and adversely affect our business, financial
condition  and  results  of  operations.

IF PRODUCT LIABILITY LAWSUITS ARE SUCCESSFULLY BROUGHT AGAINST US, WE COULD FACE
SUBSTANTIAL  LIABILITIES  THAT  EXCEED  OUR  RESOURCES.

We  may  be  held  liable  if any product our collaborators or we develop causes
injury  or  is found otherwise unsuitable during product testing, manufacturing,
marketing  or  sale.  Although we intend to obtain general liability and product
liability  insurance,  this insurance may be prohibitively expensive, or may not
fully  cover our potential liabilities. Inability to obtain sufficient insurance
coverage  at  an  acceptable  cost  or  to  otherwise  protect ourselves against
potential  product  liability  claims  could  prevent  or  inhibit  the
commercialization  of  products  developed  by  our  collaborators  or  us.

OUR  HEADQUARTERS  FACILITIES ARE LOCATED NEAR KNOWN EARTHQUAKE FAULT ZONES, AND
THE  OCCURRENCE  OF  AN  EARTHQUAKE  OR  OTHER CATASTROPHIC DISASTER COULD CAUSE
DAMAGE  TO  OUR  FACILITIES  AND  EQUIPMENT,  WHICH COULD REQUIRE US TO CEASE OR
CURTAIL  OPERATIONS.

Given  our  headquarters  location  in  South  San Francisco, our facilities are
vulnerable  to  damage  from  earthquakes.  We  are also vulnerable worldwide to
damage  from  other  types  of  disasters,  including  fire, floods, power loss,
communications  failures  and similar events. If any disaster were to occur, our
ability  to  operate  our  business  at  our  facilities  would be seriously, or
potentially completely, impaired. In addition, the unique nature of our research
activities  could cause significant delays in our programs and make it difficult
for us to recover from a disaster. The insurance we maintain may not be adequate
to  cover  our  losses resulting from disasters or other business interruptions.
Accordingly, an earthquake or other disaster could materially and adversely harm
our  ability  to  conduct  business.

FUTURE  SALES  OF  OUR  COMMON  STOCK  MAY  DEPRESS  OUR  STOCK  PRICE.

If  our  stockholders  sell  substantial  amounts of our common stock (including
shares  issued  upon  the  exercise  of outstanding options and warrants) in the
public  market,  the  market  price of our common stock could fall.  These sales
also  might  make  it  more  difficult  for  us to sell equity or equity-related
securities  in  the  future at a time and price that we deemed appropriate.  For
example,  following an acquisition, a significant number of shares of our common
stock held by new stockholders may become freely tradable.  Similarly, shares of
common  stock held by existing stockholders prior to our initial public offering
became  freely  tradable  in  2000,  subject in some instances to the volume and
other  limitations of Rule 144 of the Securities Act.  Sales of these shares and
other  shares  of  common  stock  held  by existing stockholders could cause the
market  price  of  our  common  stock  to  decline.

SOME OF OUR EXISTING STOCKHOLDERS CAN EXERT CONTROL OVER US, AND THEIR INTERESTS
COULD  CONFLICT  WITH  THE  BEST  INTERESTS  OF  OUR  OTHER  STOCKHOLDERS.

Due  to  their  combined  stock  holdings, our officers, directors and principal
stockholders  (stockholders  holding  more  than  5% of our common stock) acting
together,  may be able to exert significant influence over all matters requiring
stockholder  approval,  including  the  election  of  directors  and approval of
significant corporate transactions. In addition, this concentration of ownership
may  delay or prevent a change in control of our company, even when a change may
be  in  the  best  interests  of our stockholders. In addition, the interests of
these  stockholders  may  not always coincide with our interests as a company or
the interests of other stockholders. Accordingly, these stockholders could cause
us  to  enter  into  transactions  or  agreements that you would not approve of.

ITEM  2.  PROPERTIES

We  currently  have  commitments to lease an aggregate of 213,967 square feet of
office  and  laboratory  facilities  in  four  buildings in South San Francisco,
California.  The  first  building lease, for 33,000 square feet, expires on July
31,  2005.  The  second  building  lease  covers three buildings, one for 70,000
square  feet,  another  for  50,000  square feet and the third for 60,967 square
feet.  The  portion  of the lease for the third building is expected to begin in
March  2003.  The lease for these three buildings expires in 2017, not including
two  five-year  options to extend the term prior to expiration.  During 2002, we
also  subleased  two  additional facilities totaling 12,000 square feet in South
San  Francisco for continued expansion.  Leases for these two facilities are set
to  expire  in  2003.

We  lease  approximately  17,000  square  feet of office and laboratory space in
Portland, Oregon and own a 15-acre farm in Woodburn, Oregon. Greenhouse capacity
at  the farm currently totals 50,000 square feet.  The lease in Portland expires
on  February  28,  2006,  and there is an option to renew for an additional five
years.

We lease approximately 2,200 square feet of office and laboratory space in Koln,
Germany  and  an  additional  1,300 square feet of laboratory space in Tubingen,
Germany.  These  leases  expire  at dates ranging from March 31, 2004 to October
31,  2007.  There  is  an  option  to renew all leases for a period ranging from
three  to  five  years.

We lease approximately 41,700 square feet of office and research and development
space  in Boulder, Colorado, of which 24,000 is sublet for the remaining term of
the  lease.  This lease expires in July 2005, and there are two options to renew
for  additional  five-year terms.  We are currently attempting to sublease these
facilities.

intend  to  retain  all  future  earnings,  if  any, for use in our business and
currently  do not plan to pay any cash dividends in the foreseeable future.  Any
future  determination to pay dividends will be at the discretion of our board of
directors.

Recent  Sales  of  Unregistered  Securities

On  October  29,  2002,  Exelixis  entered  into a stock purchase agreement with
SmithKlineBeecham Corporation ("GSK") as part of a corporate alliance.  Pursuant
to  the  terms  of  the  stock purchase agreement, on November 1, 2002, Exelixis
issued  2,000,000  shares of common stock at a purchase price of $7.00 per share
to  GSK in exchange for $14.0 million in cash.  The shares were issued to GSK in
a  private placement pursuant to an exemption from registration in reliance upon
Section  4(2)  and  Rule  506  of  Regulation  D  of the Securities Act of 1933.

Uses  of  Proceeds  from  Registered  Securities

In  May 2000, we completed our initial public offering for aggregate proceeds of
approximately  $136.0  million. In connection with the offering, we paid a total
of approximately $9.5 million in underwriting discounts and commissions and $2.0
million  in other offering costs and expenses.  After deducting the underwriting
discounts  and commissions and the offering costs and expenses, our net proceeds
from  the  offering  were  approximately  $124.5  million.

From  the  time  of  receipt  through  December  31, 2002, the proceeds from the
offering  were  used  for  research  and  development  activities,  capital
expenditures, working capital, merger and acquisition expenses and other general
corporate  purposes.  All  remaining  proceeds  from  the offering were expended
during  the  fourth  quarter  of  2002.

ITEM  7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF  OPERATIONS

The following discussion and analysis contains forward-looking statements. These
statements  are  based  on  our current expectations, assumptions, estimates and
projections  about  our business and our industry, and involve known and unknown
risks,  uncertainties  and  other  factors  that may cause our or our industry's
results,  levels  of  activity,  performance  or  achievements  to be materially
different  from  any  future  results,  levels  of  activity,  performance  or
achievements  expressed  or  implied in, or contemplated by, the forward-looking
statements.  Words  such as "believe," "anticipate," "expect," "intend," "plan,"
"will,"  "may,"  "should," "estimate," "predict," "potential," "continue" or the
negative  of  such  terms or other similar expressions, identify forward-looking
statements. Our actual results and the timing of events may differ significantly
from the results discussed in the forward-looking statements. Factors that might
cause  such  a  difference  include,  but are not limited to, those discussed in
"Risk  Factors"  as  well  as those discussed elsewhere in this Annual Report on
Form 10-K . You should read the following discussion and analysis in conjunction
with the "Selected Consolidated Financial Data" and the financial statements and
notes  thereto included in this Annual Report on Form 10-K. Historical operating
results  are  not  necessarily  indicative  of  results that may occur in future
periods.  Exelixis  undertakes  no  obligation  to  update  any  forward-looking
statement  to  reflect  events  after  the  date  of  this  report.

Overview

We  believe that we are a leader in the discovery and validation of high-quality
novel targets for several major human diseases, and a leader in the discovery of
potential  new  drug  therapies, specifically for cancer and other proliferative
diseases.  Our  primary  mission is to develop proprietary human therapeutics by
leveraging  our  integrated discovery platform to increase the speed, efficiency
and  quality  of  pharmaceutical  product  discovery  and  development.

Through  our expertise in comparative genomics and model system genetics, we are
able  to  find new drug targets that we believe would be difficult or impossible
to  uncover  using  other  experimental approaches.  Our research is designed to
identify  novel  genes and proteins expressed by those genes that, when changed,
either  decrease  or  increase  the  activity in a specific disease pathway in a
therapeutically  relevant  manner.  These  genes  and  proteins represent either
potential  product  targets  or  drugs that may treat disease or prevent disease
initiation  or  progression.

Our  most  advanced proprietary pharmaceutical program focuses on drug discovery
and  development  of  small  molecules  in  cancer. Specifically, the remarkable
evolutionary  conservation of the biochemical pathways strongly supports the use
of  simple  model  systems,  such  as fruit flies, nematode worms, zebrafish and
mice,  to  identify  key components of critical cancer pathways that can then be
targeted  for  drug  discovery.  We  expect  to  develop  new  cancer  drugs  by
exploiting  the  underlying  "genetic  liabilities"  of  tumor  cells to provide
specificity in targeting these cells for destruction, while leaving normal cells
unharmed.  We  have  discovered  and  are  further  developing a number of small
molecule  drug  targets  in  addition  to  monoclonal  antibody  drug  targets.
Molecules directed against these targets may selectively kill cancer cells while
leaving  normal  cells  unharmed, and may provide alternatives or supplements to
current  cancer  therapies.

We  believe  that  our  proprietary  technologies  are  also  valuable  to other
industries  whose  products  can  be  enhanced  by  an  understanding  of DNA or
proteins,  including  the  agrochemical, agricultural and diagnostic industries.
Many  of these industries have shorter product development cycles and lower risk
than  the pharmaceutical industry, while at the same time generating significant
sales  with attractive profit margins.  By partnering with companies in multiple
industries, we believe that we are able to diversify our business risk, while at
the  same  time  maximizing  our  future  revenue  stream  opportunities.

Our  strategy  is  to  establish  collaborations  with  major  pharmaceutical,
biotechnology  and  agrochemical  companies  based  on  the  strength  of  our
technologies  and  biological  expertise  as  well  as  to  support  additional
development  of  our  proprietary  products.  Through  these  collaborations, we
obtain  license  fees  and  research  funding,  together with the opportunity to
receive  milestone  payments  and royalties from research results and subsequent
product  development.  In  addition,  many  of  our  collaborations  have  been
structured  strategically  to  provide  us  access  to technology to advance our
internal  programs, saving both time and money, while at the same time retaining
rights  to use the same information in different industries.  Our collaborations
with  leading  companies  in the agrochemical industries allow us to continue to
expand  our  internal development capabilities while providing our partners with
novel  targets  and  assays.  Since  we  believe that agrochemical products have
reduced  development  time  and lower risk, we expect to be able to maximize our
potential  future  revenue  stream through partnering in multiple industries. We
have  active  commercial  collaborations  with  several  leading pharmaceutical,
biotechnology and agrochemical companies: Bayer CropScience LP (formerly Aventis
USA  LP),  Bayer Corporation, Bristol-Myers Squibb Company (two collaborations),
Cytokinetics,  Inc.,  Dow  AgroSciences LLC, Elan Pharmaceuticals, Inc., Merck &
Co.,  Inc.  (two collaborations), Protein Design Labs, Inc., Renessen LLC, Scios
Inc.,  Schering-Plough  Research  Institute,  Inc.  and  SmithKlineBeecham
Corporation.

In  addition  to our commercial collaborations, we have relationships with other
biotechnology  companies, academic institutions and universities that provide us
access  to  specific  technology or intellectual property for the enhancement of
our  business.  These  include collaborations with leading biotechnology product
developers  and  solutions  providers,  among them Affymetrix, GeneMachines, AVI
BioPharma,  Inc.,  Silicon  Genetics, Galapagos NV, Genomics Collaborative Inc.,
Accelrys,  Inc.,  Akceli,  Inc.,  Ardais Corp., Cogen BioCognetics, Inc., Impath
Predictive  Oncology,  Inc.,  and  Virtual  Arrays,  Inc..

We  have  a  history  of  operating  losses  resulting  principally  from  costs
associated  with  research  and  development  activities,  investment  in  core
technologies  and  general  and administrative functions. As a result of planned
expenditures  for  future  research  and  development  activities,  including
manufacturing  and  development  expenses  for  compounds  in  pre-clinical  and
clinical  studies,  we  expect  to  incur  additional  operating  losses for the
foreseeable  future.

Acquisition  of  Genomica  Corporation

On  December  28,  2001, we acquired approximately 94% of the outstanding common
stock  of Genomica Corporation ("Genomica"), a bio-informatics software company.
The  acquisition  of  Genomica  was  completed  in  January  2002.  Upon  the
effectiveness  of  the  merger, Genomica became our wholly-owned subsidiary. The
transaction,  which  was  accounted for under the purchase method of accounting,
was  effected through the exchange of 0.28309 of a share of our common stock for
each  outstanding  share  of Genomica common stock. A total of approximately 6.9
million shares of our common stock were issued for all of the outstanding shares
of  Genomica  common  stock.

The  purchase  price  for  Genomica, which for financial accounting purposes was
valued  at  $110.0  million,  was  allocated  to  the  assets  acquired  and the
liabilities  assumed  based  on  their  estimated  fair  values  at  the date of
acquisition,  as determined by management based on an independent valuation.  As
a  result of this transaction, we recorded net tangible assets of $106.2 million
(including  cash  and  investments  of  $109.6 million), developed technology of
$400,000,  which will be amortized over two years, and goodwill of $3.4 million.
At  the  same  time,  we  recorded a goodwill impairment charge of $2.7 million,
which  was  expensed  in  2001  to operations.  The impairment was calculated in
accordance  with  Statement  of Financial Accounting Standards ("SFAS") No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be  Disposed  Of"  ("SFAS  121"), by estimating the present value of future cash
flows for the ongoing Genomica licensing business using a risk adjusted discount
rate.  The  impaired goodwill represented excess purchase price, which we viewed
as  economically  equivalent  to  financing  costs  for  the  acquired  cash and
investments.

In  December  2001,  in  connection  with  the acquisition of Genomica, Exelixis
adopted  an  exit  plan  for  Genomica.  Under  this  exit  plan,  we terminated
Genomica's  entire  workforce  and  abandoned  its leased facilities in Boulder,
Colorado  and  Sacramento,  California.  The  estimated  costs  of the exit plan
amounted to $2.9 million and were included as part of the liabilities assumed in
the  acquisition.

In  April 2002, we transferred the Genomica software business to Visualize, Inc.
("Visualize") for future consideration of up to $2.4 million in license fees and
royalty  payments.  Pursuant to the terms of the transaction, Visualize obtained
a  license  with all rights and obligations to third parties currently licensing
the  Genomica  software, including the sole right to further develop and license
the  software to other third parties.  Royalties that Exelixis receives, if any,
will  be  recorded  in  the  period  they are earned as a gain from discontinued
operations.  In  addition, Visualize assumed our lease obligation for Genomica's
abandoned  facility in Sacramento, California.  Exelixis retains an internal use
license  for  the  software.  As  a  result of this transaction, we reported the
operating  results of Genomica and the estimated loss on the sale of Genomica as
discontinued  operations.  For  the  period  beginning  January  1,  2002 to its
disposal  in  April  2002, Genomica's operating results consisted of revenues of
approximately $58,000 and an operating loss of approximately $456,000.  The loss
on  the  sale  of  Genomica  includes the write-off of goodwill of approximately
$971,000, partially offset by an adjustment to the estimated lease obligation by
approximately  $176,000 related to the Sacramento facility assumed by Visualize.

As  of  December 31, 2002, the remaining actions to be taken under the exit plan
consisted primarily of residual payments related to the lease obligation for the
facility  in  Boulder,  Colorado,  which  are  expected  to  continue  until the
termination  of  the  lease  in  2005, unless the facility is subleased earlier.

Beginning  in  the  first  quarter  of  2002,  we  have applied the new rules of
accounting  for goodwill and other intangible assets in accordance with SFAS No.
142, "Goodwill and Other Intangible Assets" ("SFAS 142").  Accordingly, goodwill
and  other  intangible  assets  deemed  to  have  indefinite lives are no longer
amortized  but  are  subject  to  annual  impairment  tests.

Acquisition  of  Artemis  Pharmaceuticals

In  May 2001, we acquired a majority of the outstanding capital stock of Artemis
Pharmaceuticals  GmbH, a privately held genetics and functional genomics company
organized  under  the laws of Germany.  The transaction, which was accounted for
under  the  purchase  method of accounting, was effected through the exchange of
shares  of  our  common  stock  for Deutschmark 1.00 of nominal value of Artemis
capital  stock,  using  an  exchange  ratio  of  4.064 to one. Approximately 1.6
million  shares  of  our  common  stock  were  issued in exchange for 78% of the
outstanding  capital stock of Artemis held by Artemis stockholders. In addition,
we received a call option (the "Call Option") from, and issued a put option (the
"Put Option") to, certain stockholders of Artemis (the "Option Holders") for the
issuance  of  approximately  460,000  additional  shares  of our common stock in
exchange  for the remaining 22% of the outstanding capital stock of Artemis held
by the Option Holders.  We could have exercised the Call Option at any time from
May  14,  2001  through  January  31,  2002,  and  the Option Holders could have
exercised  their  rights  under  the  Put  Option at any time from April 1, 2002
through  May  15,  2002.  We  exercised  the  Call Option for 131,674 shares and
329,591  shares  in December 2001 and January 2002, respectively, which resulted
in  an  increase  to  goodwill  of  approximately $1.9 million and $4.0 million,
respectively,  related  to the additional purchase price. In addition, we issued
fully  vested  rights to purchase approximately 187,000 additional shares of our
common stock to Artemis employees in exchange for such employees' vested options
formerly  representing  the  right  to  purchase shares of Artemis capital stock
pursuant to the Artemis Employee Phantom Stock Option Program.  Artemis provides
us  with  technologies related to the following two species: zebrafish and mice.
These  technologies  are  used  in  our  research  and  development  efforts.

The  purchase  price  for  Artemis,  which for financial accounting purposes was
valued  at  $28.2  million,  was  allocated  to  the  assets  acquired  and  the
liabilities  assumed  based  on  their  estimated  fair  values  at  the date of
acquisition,  as  determined  by management based upon an independent valuation.
As  a  result  of  this  transaction,  we  recorded  expense associated with the
purchase  of  in-process  research and development of $6.7 million, net tangible
assets  of  $2.8  million  and  intangible  assets (including goodwill) of $18.7
million,  the majority of which was being amortized over 15 years until December
31,  2001.  Under  SFAS  142,  we  have  applied the new rules of accounting for
goodwill  and  other  intangible  assets.  Accordingly,  goodwill  and  other
intangible  assets  deemed  to have indefinite lives are no longer amortized but
are  subject  to  annual  impairment  tests  in  accordance  with  SFAS  142.

Since  the third quarter of 2002, we have undertaken a strategic initiative with
respect  to  our  mouse business at Artemis, and intend to split off the entity,
including  all  personnel,  and  create  a  separate  independent company.  This
activity  is  expected  to  occur  in  2003.

Acquisition  of  Exelixis  Plant  Sciences  (Formerly  Agritope)

In December 2000, we completed our acquisition of Agritope, Inc.  As a result of
the  acquisition,  Agritope  became  our  wholly-owned  subsidiary,  and  we
subsequently changed its name to Exelixis Plant Sciences, Inc.  The transaction,
which  was  accounted  for under the purchase method of accounting, was effected
through the exchange of 0.35 of a share of our common stock for each outstanding
share  of Agritope capital stock. Approximately 1.7 million shares of our common
stock  were  issued  in connection with the transaction.  In addition, unexpired
and  unexercised  options  and  warrants  to purchase shares of Agritope capital
stock  were  assumed  by us pursuant to the transaction and converted into fully
vested  options  and  warrants  to  purchase approximately 880,000 shares of our
common  stock.

The  purchase  price  for  Agritope, which for financial accounting purposes was
valued  at  $93.5  million,  was  allocated  to  the  assets  acquired  and  the
liabilities  assumed  based  on  their  estimated  fair  values  at  the date of
acquisition,  as  determined  by  an independent valuation.  As a result of this
transaction,  we  recorded  expense  associated  with the purchase of in-process
research  and  development  of  $38.1  million, net tangible liabilities of $3.6
million  and  intangible  assets  (including  goodwill)  of  $58.9  million, the
majority  of  which  was  being amortized over 15 years until December 31, 2001.
Under  SFAS  142,  we  have applied the new rules of accounting for goodwill and
other  intangible  assets  beginning in the first quarter of 2002.  Accordingly,
goodwill  and  other  intangible  assets  deemed to have indefinite lives are no
longer  amortized  but are subject to annual impairment tests in accordance with
SFAS  142.

We  acquired  Vinifera,  Inc.  ("Vinifera")  in  connection with the purchase of
Agritope (which was the parent company of Vinifera). Vinifera was organized as a
majority-owned  subsidiary  and  was  engaged  in  the  grape  vine  propagation
business.  Because  this  business  did not fit our strategic objectives, at the
date of the acquisition of Agritope, we committed to a plan to sell the Vinifera
operations.  On  March  31,  2001, we reduced our ownership interest in Vinifera
from  57%  to 19% by selling 3.0 million shares of Vinifera common stock back to
Vinifera in consideration for $2.1 million in interest bearing promissory notes.
As  a  result  of  the  sale  of  Vinifera  common  stock  back  to Vinifera, we
deconsolidated  Vinifera,  excluded our share of Vinifera's operating losses for
the  first  quarter of 2001 of $275,000 and recorded the following amounts as an
adjustment  to goodwill recorded in connection with the acquisition of Agritope:
a  write-down  of  the  value  of  acquired developed technology attributable to
Vinifera  of  $435,000,  a  gain  on  sale  of Vinifera shares of $590,000 and a
promissory  note  reserve  of $1,700,000.  The net adjustment was an increase to
goodwill  in  the amount of $675,000.  Beginning April 1, 2001, we accounted for
our  remaining  investment  in  Vinifera  using  the  cost  method.

Due  to  risks  associated with collection, as of December 31, 2001, we reserved
for  100%  of  these  promissory  notes.  Due  to  a  significant decline in the
operating performance of Vinifera, in December 2001, we wrote down our remaining
cost-basis  investment in Vinifera to zero.  Vinifera ceased operations in 2002.

Critical  Accounting  Policies

We  believe  the  following  are  our  critical  accounting  policies:

  Revenue  Recognition

Most  of  our  revenues  are  generated  from  complex  research  and  licensing
arrangements.  These  research  and  licensing arrangements may include up-front
non-refundable  payments.  Although  these  up-front  payments  are  generally
non-refundable,  under U.S. generally accepted accounting principles ("GAAP") we
defer  the  revenues  under  these  arrangements and recognize the revenues on a
straight-line  basis  over  the  relevant  periods  specified in the agreements,
generally  the  research  term.  Our  research and license arrangements may also
include  milestone  payments.  Although  these  milestone payments are generally
non-refundable  once  the  milestone  is  achieved,  we  recognize the milestone
revenues  on  a  straight-line  basis over the research term of the arrangement.
This  typically  results  in  a portion of the milestone being recognized at the
date  the  milestone  is  achieved,  and  the  balance being recognized over the
remaining research term of the agreement.  It is our understanding that there is
diversity  in practice on the recognition of milestone revenue.  Other companies
have  adopted  an  alternative  acceptable  milestone revenue recognition policy
whereby  the  full milestone fee is recognized upon completion of the milestone.
If  we  had  adopted  such  a  policy,  our revenues recorded to date would have
increased and our deferred revenues would have decreased by an immaterial amount
compared  to  total  revenue recognized.  Revenues from chemistry collaborations
are  generally  recognized  upon  the  delivery  of  accepted  compounds.

  Exit  Costs

Prior  to  the  completion  of the December 28, 2001 acquisition of Genomica, we
formulated  an exit plan for Genomica to improve the operating efficiency of the
combined  company.  This  plan  called for the reduction of substantially all of
Genomica's  workforce  and  the  abandonment  of  leased  facilities in Boulder,
Colorado and Sacramento, California.  These activities were completed during the
first  half  of 2002.  The actual costs related to the remaining exit activities
may  differ  from the amounts recorded as of December 31, 2002.  For example, we
have  reserved  $825,000  as  of  December  31,  2002  for our estimated maximum
obligation under Genomica's remaining operating lease commitment. However, these
operating  lease commitments may be resolved in a more favorable manner, such as
the  possibility  of  successfully  subleasing  the  abandoned  space.

  Goodwill  and  Intangible  Impairment

As  of  December 31, 2002, our consolidated balance sheet included approximately
$72.2  million  of  goodwill  and other intangible assets.  Under U.S. generally
accepted  accounting  principles, we will evaluate goodwill for impairment on an
annual  basis  and  on  an  interim  basis if events or changes in circumstances
between  annual  impairment tests indicate that the asset might be impaired.  We
will  also  evaluate  other  intangible  assets  for  impairment when impairment
indicators  are identified.  In assessing the recoverability of our goodwill and
other  intangibles,  we  must  make  assumptions regarding estimated future cash
flows  and  other  factors to determine the fair value of the respective assets.
These  estimates  include forecasted revenues, which are inherently difficult to
predict.  If  these estimates or their related assumptions change in the future,
we  may be required to record impairment charges for these assets.  Furthermore,
our  impairment  evaluation  of  goodwill  will  require  management to exercise
judgment  in the identification of our reporting units.  The impairment test for
goodwill  will  be performed at the reporting unit level, which may be one level
below  the  single  operating  segment  disclosed  in  our  current  financial
statements,  depending  upon  whether  certain  criteria  are  met.

Results  of  Operations

Comparison of Fiscal Years Ended December 31, 2002, 2001 and 2000

    Total  Revenues

Total revenues were $44.3 million for the year ended December 31, 2002, compared
to  $41.0 million for 2001 and $24.8 million for 2000. The increase from 2001 to
2002  resulted  primarily  from  the impact of our corporate collaborations with
SmithKlineBeecham Corporation ("GlaxoSmithKline" or "GSK"), Bristol-Myers Squibb
Company  ("BMS")  and  Protein  Design  Labs,  Inc.  ("PDL")  and  from compound
deliveries  under  our  chemistry  collaborations established with Cytokinetics,
Inc.,  Elan  Pharmaceuticals,  Inc.,  Scios  Inc.  and  Schering-Plough Research
Institute,  Inc.  to  jointly  design  custom high-throughput screening compound
libraries.  This  increase  was  partially offset by a reduction of revenue from
Pharmacia due to the February 2002 conclusion of our collaboration. The increase
from 2000 to 2001 resulted principally from license and contract revenues earned
from  the  signing  of new collaboration agreements with PDL and BMS, additional
revenues  under  our  existing  collaborative  agreements  with  Bayer, BMS, Dow
AgroSciences  LLC  and Bayer CropScience and, to a lesser extent, recognition of
the remaining deferred revenue related to the mutually agreed termination of our
collaboration  with  Pharmacia,  which  terminated  in  February  2002.

    Research  and  Development  Expenses

Research  and  development  expenses  consist  primarily  of  salaries and other
personnel-related  expenses,  facilities  costs,  supplies,  licenses  and
depreciation  of  facilities and laboratory equipment.  Research and development
expenses  were  $112.0 million for the year ended December 31, 2002, compared to
$82.7  million  for  2001 and $51.7 million for 2000.  The increase in 2002 over
2001  resulted  primarily  from  the  following  costs:

     -    Increased  Personnel  -  Staffing  costs  in  2002  increased  by
          approximately 34% from 2001 levels to approximately $43.0 million. The
          increase  was  to  support  new  collaborative  arrangements  and  our
          internal proprietary research efforts. Salary, bonuses, related fringe
          benefits,  recruiting  and  relocation costs are included in personnel
          costs.  We  expect  these  personnel  costs  to increase further as we
          continue  to  build  our  organization.

     -    Increased Lab Supplies - As a result of the increase in personnel, our
          compound  collaborations  and  the  significant  expansion of our drug
          discovery  operations,  lab  supplies  expense  increased 41% to $21.8
          million  during  2002.

     -    Increased  Licenses  and  Consulting  -  In  order  to  support  new
          collaborative  arrangements,  manufacture  the  rebeccamycin analog to
          ensure  adequate  clinical  supply,  complete  data  analysis  for the
          ongoing NCI-sponsored Phase II trials, plan for registration trials of
          the rebeccamycin analog and to advance XL 784, our lead IND candidate,
          through  preclinical  toxicology  testing in anticipation of filing an
          IND,  license  and consulting expenses increased 128% to $12.8 million
          during  2002.

We  expect  that  research and development expenses will continue to increase in
absolute  dollar amounts in the future, as we continue to advance drug discovery
and  development  programs,  including  manufacturing  and  clinical development
efforts  on  our  maturing  pipeline  of  products.

With  respect to the rebeccamycin analogue and our own proprietary compounds, we
are  currently  relying  on collaborators and third-party contractors to produce
materials  for  clinical  trials.  We expect clinical costs will increase in the
future  as  we  enter  clinical  trials  for  proprietary product candidates and
additional  trials  for  our  rebeccamycin analogue, if any. We currently do not
have estimates of total costs to reach the market by a particular drug candidate
or  in  total.  Our  potential therapeutic products are subject to a lengthy and
uncertain  regulatory  process  that  may not result in the necessary regulatory
approvals,  which  could adversely affect our ability to commercialize products.
In  addition,  clinical trials of our potential products may fail to demonstrate
safety  and  efficacy,  which  could  prevent  or significantly delay regulatory
approval.

Our  most  advanced clinical program is the rebeccamycin analogue ("XL 119"), an
anticancer  compound  that  we  in-licensed  from  BMS in 2001. The rebeccamycin
analogue  has  completed Phase I testing. The Phase II clinical testing program,
which  is  being  conducted  by  the  National Cancer Institute ("NCI"), is well
advanced.  To date, the most pronounced antitumor activity was observed in upper
gastrointestinal  tumors  (most  prominently in bile duct tumors), where several
partial  responses and instances of prolonged disease stabilization occurred. We
believe  that  the  compound  deserves  further development efforts, as there is
currently  no approved standard therapy for these rapidly progressing tumors. We
anticipate initiating next development steps, if any, following discussions with
the  Food  and  Drug  Administration  ("FDA").

XL  784 is the first small molecule compound developed from our proprietary drug
discovery  platform.  We are currently completing regulatory toxicology studies,
and if the safety profile continues to look acceptable, we expect to file an IND
in  2003.

The  increase  in  research  and development expenses from 2001 and 2000 was due
primarily  to  increased staffing and other personnel-related costs and non-cash
stock  compensation  expense (as described below).  These expenses were incurred
to  support  new  collaborative  arrangements  and  proprietary  programs.

     -    Increased  Personnel  -  Staffing  costs  in  2001  increased  by
          approximately  69%  to  approximately  $32.0  million  from  2000. The
          increase  was  to  support  new  collaborative  arrangements  and  our
          internal  proprietary  research  efforts, including increased expenses
          related to staff hired with the acquisition of Artemis in May 2001 and
          Agritope  in  December 2000. Salary, bonuses, related fringe benefits,
          recruiting  and  relocation  costs  are  included  in personnel costs.

     -    Increased  Lab Supplies - As a result of the increase in personnel and
          the  significant  expansion  of  our  drug  discovery  operations, lab
          supplies  increased  85%  to  approximately $15.5 million during 2001.

     -    Increased  Licenses  and  Consulting  -  To  support new collaborative
          arrangements  and further development of proprietary programs, license
          and  consulting  expenses increased 100% to approximately $5.6 million
          during  2001.

    General  and  Administrative  Expenses

General  and  administrative  expenses  consist  primarily  of staffing costs to
support  our  research  activities,  facilities costs and professional expenses,
such  as  legal fees. General and administrative expenses were $18.8 million for
the  year  ended December 31, 2002, compared to $19.2 million for 2001 and $15.7
million  for  2000.  The  decrease  in  2002  from  2001  was primarily due to a
decrease  in  non-cash  stock compensation expense of $1.5 million (as described
below),  partially  offset  by costs associated with personnel and facilities to
support  expansion  in our research and development operations.  The increase in
general  and  administrative expenses in 2001 compared to 2000 was primarily due
to  increased  staffing  in  support  of  our  expanded research and development
activities,  partially  offset  by  a  decrease  in  non-cash stock compensation
expense  of  $2.2  million  (as  described  below).

    Stock  Compensation  Expense

Deferred  stock  compensation  for  options  granted  to  our  employees  is the
difference between the fair value for financial reporting purposes of our common
stock  on  the date such options were granted and their exercise price. Deferred
stock  compensation for options granted to consultants has been determined based
upon  estimated  fair value, using the Black-Scholes option valuation model.  As
of  December  31, 2002, we have approximately $1.0 million of remaining deferred
stock  compensation,  related  to  stock  options  granted  to  consultants  and
employees.  In  connection  with  the  grant  of  stock options to employees and
consultants,  we  recorded  no  deferred  stock  compensation in the years ended
December  31, 2002 and 2001 and $10.0 million in 2000.  This amount was recorded
as  a  component  of  stockholders'  equity  and  is  being  amortized  as stock
compensation expense over the vesting periods of the options, which is generally
four  years.  We  recognized  stock compensation expense of $2.5 million for the
year  ended  December  31,  2002,  compared  to  $7.4 million for 2001 and $14.0
million  for  2000.  These  amounts are included within research and development
and  general  and  administrative expenses.  The decreases in stock compensation
expense  in  2002 compared to 2001 and in 2001 compared to 2000 primarily result
from  the  accelerated  amortization  method  used  for  accounting  purposes.

During  April  2001, we granted approximately 545,000 supplemental stock options
("Supplemental  Options")  under  the  2000  Equity  Incentive  Plan  to certain
employees (excluding officers and directors) who had stock options with exercise
prices  greater  than $16.00 per share under the 2000 Equity Incentive Plan. The
number  of  Supplemental  Options  granted was equal to 50% of the corresponding
original grant held by each employee.  The Supplemental Options have an exercise
price  of  $16.00,  vest monthly over a two-year period beginning April 1, 2001,
and  have  a  27-month  term.  The  vesting  on the corresponding original stock
options  was suspended and will resume in April 2003 following the completion of
vesting  of  the  Supplemental  Options.  This new grant constitutes a synthetic
repricing  as  defined  in  Financial  Accounting  Standards  Board  ("FASB")
Interpretation  Number  44, "Accounting for Certain Transactions Involving Stock
Compensation,"  and results in certain options being reported using the variable
plan method of accounting for stock compensation expense until those options are
exercised,  forfeited  or  expire.  For  the  year  ended  December 31, 2001, we
recorded compensation expense related to these Supplemental Options of $246,000,
of  which $242,000 was reversed in 2002 due to a decrease in the market value of
our  common  stock.

    Acquired  In-Process  Research  and  Development

The  valuation  of  the purchased in-process research and development related to
the  Artemis acquisition of $6.7 million was determined by management based upon
the  results  of  an independent valuation using the income approach for each of
the  three  significant  in-process  projects.  The  in-process  projects relate
primarily  to  the development of technologies that use vertebrate genetic model
organisms,  zebra-fish  and  mice,  to  identify and functionally validate novel
genes  in  vivo.  These  genes  can be used as novel screening targets or as the
basis  for  secreted  proteins in clinically and commercially relevant diseases.
The in-process projects have been abandoned or are expected to be completed over
approximately  the  next  two years.  The income approach estimates the value of
each  acquired  in-process  project based on its expected future cash flows. The
valuation analysis considered the contribution of the core technology as well as
the  percent  complete  of each in-process research and development project. The
expected present value of the cash flows associated with the in-process research
and  development  projects  was computed using a risk adjusted rate of return of
30%, which is considered commensurate with the overall risk and percent complete
of  the  in-process  projects.  The  purchased  in-process  technology  was  not
considered  to have reached technological feasibility, and it has no alternative
future  use,  and  accordingly,  it  was  recorded  as  a component of operating
expenses.

In  connection  with  the  Agritope  purchase  in  fiscal year 2000, we recorded
expense  of  $38.1  million  relating  to  acquired  in-process  research  and
development.  The valuation of the purchased in-process research and development
was based upon the results of an independent valuation using the income approach
for  each  of  the  ten  projects  in-process.  The  in-process  projects relate
primarily  to  the  development  of  disease  and  insect  resistant  fruits and
vegetables  and  have  been  abandoned  or  are  expected  to  be completed over
approximately  the  next three and one-half years. The income approach estimates
the  value of each acquired in-process project based on its expected future cash
flows. The valuation analysis considered the contribution of the core technology
as  well  as  the  percent  complete of each in-process research and development
project.  The  expected  present  value  of  the  cash flows associated with the
in-process  research and development projects was computed using a risk adjusted
rate  of  return  of 35%, which is considered commensurate with the overall risk
and  percent  complete  of the in-process projects. The purchased technology was
not  considered  to  have  reached  technological  feasibility,  and  it  has no
alternative future use, accordingly, it was recorded as a component of operating
expense.

    Impairment  of  Goodwill

In  2001,  we  acquired $3.4 million of goodwill in connection with our Genomica
acquisition.  At the same time, we recorded a goodwill impairment charge of $2.7
million,  which  was  expensed  in  2001  to  operations.  The  impairment  was
calculated  in  accordance  with  SFAS  121,  by estimating the present value of
future  cash  flows  for  the  ongoing  Genomica licensing business using a risk
adjusted  discount  rate.  The  impaired  goodwill  represented  excess purchase
price,  which  we  viewed  as economically equivalent to financing costs for the
acquired  cash  and  investments.

We  adopted SFAS 142 on January 1, 2002.  This accounting standard requires that
goodwill  no  longer  be  amortized,  and instead, be tested for impairment on a
periodic  basis.  We  completed  a transitional impairment test during the first
quarter  of  2002,  which did not result in impairment of recorded goodwill.  We
adopted  an  annual  goodwill  impairment  test  date as of the beginning of the
fourth quarter of 2002.  Accordingly, we completed the annual impairment test as
of  October  1,  2002,  which did not result in impairment of recorded goodwill.

    Amortization  of  Goodwill  and  Other  Intangibles

Goodwill  and  intangibles result from our acquisitions of Genomica, Artemis and
Agritope  (renamed  Exelixis  Plant  Sciences).  Amortization of intangibles was
$666,000  for  the  year  ended  December  31, 2002, compared to amortization of
goodwill  and  intangibles  of $5.1 million for 2001 and $260,000 for 2000.  The
decrease  in  2002  from 2001 was primarily related to our adoption of SFAS 142,
whereby goodwill is no longer amortized.  The increase in 2001 over 2000 was the
result of amortization of goodwill and intangibles from the Agritope acquisition
for  12 months compared to only one month in 2000 as well as the amortization of
goodwill  and  intangibles  from  the  acquisition  of  Artemis.

    Restructuring  Charge

During  the  fourth  quarter of 2002, we implemented a restructuring plan, which
resulted  in  a  reduction  in workforce of 40 employees primarily from our U.S.
research  operations.  Accordingly,  we  recorded  a  restructuring  charge  of
$708,000  comprised  primarily  of  involuntary  termination  benefits.  The
restructuring  plan  was implemented in order to facilitate our evolution into a
fully  integrated  drug  discovery  company and the reallocation of resources to
permit  greater  focus  on  building  our  expanding  portfolio  of  development
programs.

    Other  Income  (Expense),  Net

Other  income,  net,  was  $3.3  million  for  the year ended December 31, 2002,
compared  to  $4.1  million  for  2001  and $5.6 million for 2000.  Other income
(expense) consists primarily of interest income earned on cash, cash equivalents
and  short-term  investments,  offset  by  interest  expense  incurred  on notes
payable,  bank  obligations and capital lease obligations.  The decrease in 2002
from  2001  was  the  result  of a decrease in interest income due to an overall
decline  in  interest rates coupled with an increase in interest expense related
to  notes  payable  and  bank  obligations.  The  decrease in 2001 from 2000 was
primarily  attributable  to  an  increase  in  interest expense related to notes
payable  and  capital  leases.

    Discontinued  Operations

In  April  2002,  we transferred the Genomica software business to Visualize for
future consideration of up to $2.4 million in license fees and royalty payments.
Pursuant  to the terms of the transaction, Visualize obtained a license with all
rights  and  obligations  to  third  parties  currently  licensing  the Genomica
software,  including  the sole right to further develop and license the software
to  other third parties.  Royalties that we receive, if any, will be recorded in
the  period  they are earned as a gain in discontinued operations.  In addition,
Visualize  assumed  the  lease  obligation  for Genomica's abandoned facility in
Sacramento,  California.  We  retained an internal use license for the software.
As  a  result of this transaction, we reported the operating results of Genomica
and  the estimated loss on the sale of Genomica as discontinued operations.  For
the  period  beginning  January  1,  2002 and ending with the discontinuation of
Genomica's  operations  in April 2002, Genomica's operating results consisted of
revenues  of  approximately  $58,000  and  an  operating  loss  of approximately
$456,000.  The  loss  on the sale of Genomica includes the write-off of goodwill
of  approximately  $971,000,  partially  offset  by  a  change  in  estimate for
Genomica's  lease obligation for the Sacramento facility assumed by Visualize of
approximately  $176,000.

    Minority  Interest  and  Equity  in  Net  Loss  of  Affiliated  Company

On  March  31, 2001, we reduced our ownership interest in Vinifera, Inc. to 19%.
Beginning  April  1, 2001, we accounted for our remaining investment in Vinifera
using  the  cost  method.  Due  to  a  significant  decline  in  the  operating
performance  of  Vinifera,  we  wrote down our investment in Vinifera to zero in
December  2001.

For  2000,  minority  interest  in  subsidiary  net loss represents the minority
shareholders'  portion  of  Vinifera's operating loss.  Net loss reported by us,
which  is  attributable to the minority shareholders, was approximately $100,000
in  2000.  Since  we  owned  in  excess  of  50%  of  Vinifera,  we consolidated
Vinifera's  operating  results,  a  portion  of  which was then allocated to the
minority  shareholders  as  minority  interest  in proportion to their ownership
interest,  partially  offsetting  our  operating  loss.

    Income  Taxes

We have incurred net losses since inception and, consequently, have not recorded
any  U.S.  federal  or  state income taxes.  We have recorded a tax provision of
approximately  $345,000  for  the year ended December 31, 2002 related to income
earned  in  our  foreign  operations.

As  of  December  31,  2002,  we  had  federal and California net operating loss
carryforwards of approximately $76.6 million and $36.7 million, respectively. We
had federal research and development credit carryforwards of approximately $10.8
million  in  each  jurisdiction.  If  not  utilized,  the net operating loss and
credit  carryforwards  expire  at  various  dates  beginning in 2005.  Under the
Internal  Revenue Code and similar state provisions, certain substantial changes
in  our  ownership  could  result  in  an annual limitation on the amount of net
operating  loss and credit carryforwards that can be utilized in future years to
offset future taxable income. Annual limitations may result in the expiration of
net  operating  loss  and  credit  carryforwards  before  they  are  used.

Liquidity  and  Capital  Resources

Since  inception,  we have financed our operations primarily through the sale of
equity,  equipment  lease financings and other loan facilities and payments from
collaborators.  Our  initial public offering, completed in the second quarter of
2000,  raised  $124.5  million  in  net  cash proceeds. In addition, we acquired
Genomica  in December 2001, including $109.6 million in cash and investments. As
of  December  31,  2002,  we  had  approximately  $222.0  million  in cash, cash
equivalents,  short-term  investments  and  restricted  cash.

Our  operating activities used cash of $30.9 million for the year ended December
31,  2002,  compared  to $23.8 million for 2001 and $12.9 million for 2000. Cash
used  in  operating activities during each year related primarily to funding net
losses,  partially offset by an increase in deferred revenue from collaborators,
non-cash  charges  related  to  acquired  in-process  research  and development,
depreciation  and  amortization  of deferred stock compensation and intangibles.

Our  investing  activities  provided  cash  of  $46.8 million for the year ended
December  31,  2002, compared to cash provided of $5.4 million for 2001 and cash
used  of  $96.4 million for 2000.  Cash provided in 2002 resulted primarily from
the maturities and sales of short-term investments, offset by purchases of other
short-term  investments.  The  cash provided in 2001 consisted of cash resulting
from  the  acquisitions of Artemis and Genomica and proceeds from maturities and
sales  of  short-term  investments,  partially offset by purchases of short-term
investments  and  property  and  equipment.  The  use of cash for 2000 consisted
primarily  of  purchases  of  short-term investments and property and equipment,
partially  offset  by  proceeds  from  maturities  of short-term investments and
proceeds  from  sale-leaseback  of  equipment.  We  expect  to  continue to make
significant  investments  in  research  and  development  and our administrative
infrastructure,  including the purchase of property and equipment to support our
expanding  operations.

Our  financing  activities  provided  cash  of  $32.6 million for the year ended
December  31,  2002,  compared  to $34.4 million for 2001 and $123.5 million for
2000.  Cash  provided  from financing activities in 2002 resulted primarily from
$25.0 million from a convertible note with GSK, in addition to $6.8 million from
the  issuance  of  common  stock  to  GSK,  both  in accordance with an executed
collaboration  agreement.  The  cash  provided from financing activities in 2002
was  partially  offset by principal payments on capital leases, bank obligations
and  notes  payable.  The  cash  provided  in  2001  consisted  of $10.0 million
proceeds  from  the  issuance  of common stock to BMS as part of a collaboration
agreement and $30.0 million proceeds from a convertible note with PDL, partially
offset by principal payments on capital leases and notes payable.  Cash provided
from  financing  activities  in  2000  consisted  primarily of proceeds from our
initial  public  offering.

We  believe  that  our current cash and cash equivalents, short-term investments
and funding to be received from collaborators, will be sufficient to satisfy our
anticipated  cash  needs  for  at  least  the  next  two  years.  Changes in our
operating  plan  as well as factors described in our "Risk Factors" elsewhere in
this  Annual Report on Form 10-K could require us to consume available resources
much  sooner  than  we  expect.  It  is  possible  that  we will seek additional
financing  within  this timeframe.  We may raise additional funds through public
or  private  financing,  collaborative  relationships or other arrangements.  In
July 2001, we filed a registration statement on Form S-3 to offer and sell up to
$150.0 million of common stock.  We have no current commitments to offer or sell
securities  with  respect to shares that may be offered or sold pursuant to that
filing.  We  cannot  assure  you  that  additional  funding,  if sought, will be
available  or,  even  if  available, will be available on terms favorable to us.
Further,  any  additional  equity financing may be dilutive to stockholders, and
debt  financing, if available, may involve restrictive covenants. Our failure to
raise  capital  when  needed  may  harm  our  business  and  operating  results.

Commitments

We  do  not  have  any "special purpose entities" that are unconsolidated in our
financial  statements  that are reasonably likely to materially affect liquidity
or  the  availability  or  requirements  of cash.  We are also not involved with
non-exchange  traded commodity contracts accounted for at fair value. We have no
commercial commitments with related parties, except for employee loans.  We have
contractual  obligations  in  the  form  of  operating and capital leases, notes
payable  and  licensing  agreements.  These  are  described in further detail in
Notes 8 and 12 of the Notes to Consolidated Financial Statements.  The following
chart  details  our  contractual  obligations  (in  thousands):

We  had outstanding loans aggregating $904,000 and  $937,000 to certain officers
and  employees  as  of  December  31, 2002 and 2001, respectively. The notes are
general  recourse  or  collateralized  by  certain  real  property  assets, bear
interest  at  rates  ranging from 4.6% to 7.0% and have maturities through 2006.
The principal plus accrued interest will be forgiven at various rates over three
to  four  years  from  the employees' date of employment with us. If an employee
leaves  us,  all  unpaid  and  unforgiven principal and interest will be due and
payable  within  60  days.

As  of  December  31, 2002, we had outstanding loans aggregating $1.2 million to
our stockholders.  The loans were issued to enable certain employees to purchase
stock  pursuant  to  their  employee  stock options.  The loans bear interest at
rates  ranging  from 6.13% to 6.50% and mature at various times through February
2004.

Recent  Accounting  Pronouncements

We  implemented  SFAS 142 on January 1, 2002.  This accounting standard requires
that goodwill no longer be amortized, and instead, be tested for impairment on a
periodic basis.  Accordingly, we completed a transitional impairment test during
the  first  quarter  of  2002,  which  did  not result in impairment of recorded
goodwill.  We  adopted  an  annual  goodwill  impairment  test  date  as  of the
beginning of the fourth quarter of 2002.   Following this approach, we completed
the  annual  impairment  test  as  of  October  1, 2002, which did not result in
impairment  of  recorded  goodwill.  We  will continue to monitor asset-carrying
values  as  of October 1, assess if there is a potential impairment and complete
the  measurement  of  impairment,  if  required.  We will perform the impairment
measurement  procedures  under SFAS No. 142 if it is determined that a potential
impairment  of  goodwill  exists.

We  adopted  SFAS  No.  144,  "Accounting  for  the  Impairment  or  Disposal of
Long-Lived  Assets," ("SFAS 144") on January 1, 2002 .  SFAS 144 supersedes SFAS
121,  "Accounting  for  the  Impairment  of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of" ("SFAS 121").  The primary objectives of SFAS 144 were
to  develop  one accounting model based on the framework established in SFAS 121
for  long-lived  assets  to  be  disposed  of by sale and to address significant
implementation  issues.  The adoption of SFAS 144 did not have a material impact
on  our  financial  position  or  results  of  operations.

In  June  2002,  the FASB issued SFAS 146, "Accounting for Costs Associated with
Exit  or  Disposal  Activities"  ("SFAS  146"),  which  addresses accounting for
restructuring,  discontinued operations, plant closing or other exit or disposal
activity.  SFAS  146  requires companies to recognize costs associated with exit
or  disposal  activities  when  they  are  incurred rather than at the date of a
commitment to an exit or disposal plan.  SFAS 146 is to be applied prospectively
to  exit  or  disposal  activities  initiated  after December 31, 2002, although
earlier  adoption  is  permitted.  We  adopted SFAS 146 in the fourth quarter of
2002,  with  no  significant  impact  on  our  financial  position or results of
operations.

ITEM  7A.  QUANTITATIVE  AND  QUALITATIVE  DISCLOSURES  ABOUT  MARKET  RISK

Our  exposure  to market risk for changes in interest rates relates primarily to
our investment portfolio and our long-term debt. At December 31, 2002, and 2001,
we had investments in debt securities of approximately $213.8 million and $223.2
million,  respectively.  Our  investments are subject to interest rate risk, and
our  interest  income  may  fluctuate  due to changes in U.S. interest rates. By
policy, we limit our investments to money market instruments, debt securities of
U.S.  government  agencies  and debt obligations of U.S. corporations. We manage
market  risk  by our diversification requirements, which limit the amount of our
portfolio  that  can  be  invested  in a single issuer. We manage credit risk by
limiting  our  purchases to high-quality issuers. Through our money managers, we
maintain risk management control systems to monitor interest rate risk. The risk
management  control  systems  use  analytical  techniques, including sensitivity
analysis.  At  December 31, 2002, and 2001, we had long-term debt outstanding of
approximately  $65.3  million  and  $41.8  million,  respectively.  Our  payment
commitments  associated  with  these  debt  instruments  are  fixed  during  the
corresponding  terms and are comprised of interest payments, principal payments,
or  a  combination  thereof. The fair value of our long-term debt will fluctuate
with  movements  of  interest rates, increasing in periods of declining rates of
interest,  and  declining  in  periods  of  increasing  rates  of  interest.

We  have  estimated  the estimated effects on our interest rate sensitive assets
and  liabilities  based  on  a  one  percentage  point  hypothetical increase or
decrease  in interest rates as of December 31, 2002 and 2001. As of December 31,
2002,  a decrease in the interest rates of one percentage point would have a net
adverse  change  in  the  fair  value  of  interest  rate  sensitive  assets and
liabilities of approximately $1.6 million.  As of December 31, 2001, an increase
in the interest rates of one percentage point would have a net adverse change in
the  fair  value  of  interest  rate  sensitive  assets  and  liabilities  of
approximately  $0.1  million.  It  is  assumed the changes occur immediately and
uniformly  to  each  category  of  instrument  containing  interest  rate risks.
Significant  variations  in  market  interest rates could produce changes in the
timing of repayments due to available prepayment options. The fair value of such
instruments  could  be affected and, therefore, actual results might differ from
our  estimate.

We  are  exposed  to  foreign currency exchange rate fluctuations related to the
operations  of  our German subsidiaries. The revenues and expenses of our German
subsidiaries  are denominated in Euro.  At the end of each reporting period, the
revenues  and  expenses  of  these subsidiaries are translated into U.S. dollars
using  the  average  currency  rate  in  effect  for  the period, and assets and
liabilities  are  translated into U.S. dollars using the exchange rate in effect
at the end of the period.  Fluctuations in exchange rates, therefore, impact our
financial  condition  and  results  of  operations  as reported in U.S. dollars.

In  February 2002, we commenced using derivative financial instruments to reduce
our  exposure  to  foreign  currency exchange rate movements on our consolidated
operating  results.  As  of  December  31, 2002, we had outstanding an aggregate
notional amount of $5.8 million of written foreign currency put option contracts
and  a notional amount of $2.9 million of purchased foreign currency call option
contracts  denominated  in Euro.  Both the put and call option contracts have an
average  exercise  price  of  $1.0289 and expire no later than October 10, 2003.
The  fair  value  of  these  contracts  at  December  31, 2002 was approximately
$119,000,  which  is  reflected  on  the balance sheet as an asset.  Our hedging
strategy is designed such that any potential losses on these instruments will be
materially  offset  in earnings by a reduction in Euro denominated costs for our
German  operations.  We  cannot  give  any assurance that our hedging strategies
will  be  effective  or  that  transaction losses can be minimized or forecasted
accurately.

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

To  the  Board  of  Directors  and  Stockholders  of  Exelixis,  Inc.

We  have  audited the accompanying consolidated balance sheets of Exelixis, Inc.
as  of  December  31,  2002 and 2001, and the related consolidated statements of
operations,  stockholders' equity and cash flows for the years then ended. These
financial  statements  are  the  responsibility of the Company's management. Our
responsibility  is  to express an opinion on these financial statements based on
our  audits.

We conducted our audits in accordance with auditing standards generally accepted
in the 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 Exelixis, Inc. at
December  31,  2002 and 2001, and the consolidated results of its operations and
its cash flows for the years then ended in conformity with accounting principles
generally  accepted  in  the  United  States.

As  discussed  in  Note 6 of the notes to consolidated financial statements, the
Company  changed  its  method  of  accounting  for goodwill and other intangible
assets.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 THE COMPANY AND A SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company

Exelixis,  Inc.  ("Exelixis"  or the "Company") is a biotechnology company whose
primary  mission  is to develop proprietary human therapeutics by leveraging its
integrated  discovery  platform to increase the speed, efficiency and quality of
pharmaceutical  product  discovery and development. The Company uses comparative
genomics  and  model  system  genetics  to  find  new drug targets that Exelixis
believes  would  be  difficult or impossible to uncover using other experimental
approaches.  The  Company's  research  is  designed  to identify novel genes and
proteins  expressed  by  those  genes,  that,  when  changed, either decrease or
increase  the  activity  in  a  specific  disease  pathway  in a therapeutically
relevant  manner.  These  genes  and proteins represent either potential product
targets  or  drugs  that  may  treat  disease  or  prevent disease initiation or
progression.  The  Company's  most  advanced  proprietary pharmaceutical program
focuses  on  drug  discovery and development of small molecules in cancer. While
the  Company's  proprietary  programs  focus  on drug discovery and development,
Exelixis  believes  that  its  proprietary  technologies  are  valuable to other
industries  whose  products  can  be  enhanced  by  an  understanding  of DNA or
proteins,  including  the  agrochemical, agricultural and diagnostic industries.

Basis of Consolidation

The  consolidated  financial  statements include the accounts of the Company and
its  wholly-owned  subsidiaries.  All  significant  intercompany  balances  and
transactions  have  been  eliminated.

The  Company  records  its  minority  ownership  interests  in Genoptera LLC and
Agrinomics  LLC  using  the  equity  method  of  accounting.

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 reported amounts of assets and liabilities and
disclosures  of  contingent  assets and liabilities at the date of the financial
statements  and  the  reported  amounts  of  revenues  and  expenses  during the
reporting  period.  Actual  results  could  differ  significantly  from  those
estimates.

Cash, Cash Equivalents, Short-Term Investments and Restricted Cash

The  Company  considers all highly liquid investments purchased with an original
maturity of three months or less to be cash equivalents. The Company invests its
excess  cash  in high-grade, short-term commercial paper and money market funds,
which  invest  in United States ("U.S.") Treasury securities that are subject to
minimal  credit  and  market  risk.

All  short-term  investments  are classified as available-for-sale and therefore
carried  at  fair  value.  The Company views its available-for-sale portfolio as
available for use in current operations. Accordingly, the Company has classified
all  investments  as short-term, even though the stated maturity date may be one
year  or  more  beyond  the  current  balance  sheet  date.  Available-for-sale
securities  are  stated  at  fair  value  based upon quoted market prices of the
securities.  Unrealized  gains and losses on such securities, when material, are
reported  as  a  separate  component of stockholders' equity. Realized gains and
losses,  net,  on available-for-sale securities are included in interest income.
The  cost  of  securities  sold  is based on the specific identification method.
Interest  and  dividends  on  securities  classified  as  available-for-sale are
included  in  interest  income.



The following summarizes available-for-sale securities included in cash and cash
equivalents,  short-term  investments  and  restricted  cash  (in  thousands):

The  following  is  a  reconciliation  of  cash  and  cash  equivalents:


                                                           December 31,
                                                      ----------------------

Cash                                                      2,447      4,455

                                                        $84,522    $35,584
                                                      ==========  ==========


Net  unrealized  gains  were  $906,000  and $601,000 as of December 31, 2002 and
2001,  respectively.  Gross  unrealized  gains  and  losses  have not been shown
separately as they were immaterial.  Realized gains amounted to $65,000 in 2002,
$84,000  in  2001  and  none  in  2000.

Property and Equipment

Property  and  equipment  are  recorded  at  cost  and  depreciated  using  the
straight-line method over their estimated useful lives, generally three to seven
years.  Leasehold improvements are amortized over the shorter of their estimated
useful  life  or  the remaining term of the lease.  Equipment held under capital
lease  is  stated  at  the lower of the cost of the related asset or the present
value  of  the  minimum lease payments and is amortized on a straight-line basis
over  the  estimated  useful  life of the related asset. Repairs and maintenance
costs  are  charged  to  expense  as  incurred.

Intangible Assets

Intangible  assets  have  been amortized using the straight-line method over the
following  estimated  useful  lives:

  Developed  technology                           3 - 5 years
  Patents/core  technology                          15  years
  Assembled  workforce  (2001  and  prior)           3  years
  Goodwill  (2001  and  prior)                      15  years

Beginning  in  2002,  the  Company  has  applied the new rules of accounting for
goodwill  and  other intangible assets in accordance with Statement of Financial
Accounting  Standards  ("SFAS")  No. 142, "Goodwill and Other Intangible Assets"
("SFAS  142").  Accordingly, goodwill and other intangible assets deemed to have
indefinite  lives  are  no longer amortized and are subject to annual impairment
tests.

Long-lived Assets

The  Company  accounts for its long-lived assets under SFAS No. 144, "Accounting
for  the  Impairment  or  Disposal of Long-Lived Assets" ("SFAS 144") adopted on
January  1,  2002.  SFAS 144 supersedes SFAS 121, "Accounting for the Impairment
of  Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" ("SFAS 121").
SFAS  144  retains  the requirements of SFAS 121 to recognize an impairment loss
only  if  the  carrying amount of a long-lived asset is not recoverable from its
undiscounted cash flows.  During 2001, there was an impairment of goodwill under
SFAS  121 related to the Genomica purchase as detailed in Note 2 of the Notes to
Consolidated  Financial  Statements.

Income Taxes

The  Company  accounts  for  income taxes under the liability method. Under this
method,  deferred  tax assets and liabilities are determined on the basis of the
difference  between  the  income  tax  bases of assets and liabilities and their
respective  financial  reporting  amounts at enacted tax rates in effect for the
periods  in which the differences are expected to reverse. A valuation allowance
is  established  when  necessary  to  reduce  deferred tax assets to the amounts
expected  to  be  realized.

Fair Value of Financial Instruments

Carrying  amounts  of  certain of the Company's financial instruments, including
cash  and cash equivalents and short-term investments approximate fair value due
to  their  short maturities. Based on borrowing rates currently available to the
Company for loans and capital lease obligations with similar terms, the carrying
value  of  the  Company's  debt  obligations  approximates  fair  value.

Concentration of Credit Risk

Financial  instruments that potentially subject the Company to concentrations of
credit  risk  are  primarily  cash and cash equivalents, accounts receivable and
investments  in  marketable  securities.  Cash  equivalents  and  marketable
securities  consist  of  money market funds, taxable commercial paper, corporate
bonds  with  high credit quality, U.S. government agency obligations and auction
rate  securities.  All  cash,  cash  equivalents  and  marketable securities are
maintained  with  financial  institutions  that  management  believes  are
creditworthy.  Accounts  receivable are typically unsecured and are concentrated
in  the  pharmaceutical  and biotechnology industries.  Accordingly, the Company
may  be  exposed  to  credit  risk  generally associated with pharmaceutical and
biotechnology  companies.  The  Company  has  had  no  bad debt since inception.

For  the  year  ended  December  31,  2002,  revenue  from  two of the Company's
collaborators  represented  approximately  39%  and  25%  of  total  revenue,
respectively.  For  the  year ended December 31, 2001, revenue from three of the
Company's  collaborators  represented  approximately  32%,  31% and 15% of total
revenue,  respectively.  For  the year ended December 31, 2000, revenue from two
of  the  Company's  collaborators represented approximately 53% and 36% of total
revenue,  respectively.

Revenue Recognition

License,  research  commitment  and  other  non-refundable  payments received in
connection with research collaboration agreements are deferred and recognized on
a  straight-line  basis  over  the relevant periods specified in the agreements,
generally  the  research  term.  Contract  research  revenues  are recognized as
services  are  performed  pursuant  to  the terms of the agreements. Any amounts
received  in  advance of performance are recorded as deferred revenue.  Payments
are  not  refundable  if  research  is  not  successful.

Milestone  payments are non-refundable and recognized as revenue over the period
of  the  research  arrangement.  This  typically  results  in  a  portion of the
milestone  being  recognized  at  the  date  the  milestone is achieved, and the
balance  being  recognized  over  the  remaining research term of the agreement.

Revenues  from  chemistry  collaborations  are  generally  recognized  upon  the
delivery  of  accepted  compounds.

Research and Development Expenses

Research  and  development  costs  are  expensed  as  incurred and include costs
associated  with  research  performed  pursuant  to  collaborative  agreements.
Research  and  development  costs  consist of direct and indirect internal costs
related to specific projects as well as fees paid to other entities that conduct
certain  research  activities  on  behalf  of  the  Company.

Derivative Financial Instruments

The  Company manages exposures to the changes in foreign currency exchange rates
for  its foreign operations through a program of risk management adopted in 2002
that includes the use of derivative financial instruments.  The Company utilizes
derivative  financial  instruments  solely  to hedge identified exposures and by
policy  prohibits  the  use of derivative instruments for speculative or trading
purposes.  The  Company's  derivative financial instruments are recorded at fair
value  and  are  included  in  other  current  assets  or  accrued  expenses.

The  Company  enters into foreign currency exchange combination option contracts
denominated  in  European  Union Euro ("Euro") to minimize the effect of foreign
exchange  rate  movements on the cash flows related to the Company's payments to
one  of  its  German  subsidiaries  for services provided by the subsidiary. The
Company  has  designated these derivatives as foreign currency cash flow hedges.
The  effective  portion  of  the  gain  or  loss on the derivative instrument is
reported  as a separate component of other comprehensive income and reclassified
into  earnings  in  the  same period during which the hedged transaction impacts
earnings.  The  remaining gain or loss on the derivative instrument in excess of
the  cumulative  change  in  the  present  value of the future cash flows of the
hedged  item,  if  any,  is  recognized  in  other  income or expense in current
earnings  in  each  reporting  period.

If  a  cash  flow  hedge were to be discontinued because it is probable that the
original  hedged transaction will not occur as anticipated, the unrealized gains
or  losses  would  be reclassified into earnings.  Subsequent gains or losses on
the  related  derivative instrument would be recognized in income in each period
until  the  instrument  matures,  is  terminated  or  is  sold.

During  the year ended December 31, 2002, the Company did not recognize any gain
or  loss  related  to  the  ineffective  portion  of the hedging instruments and
reclassified  a  gain  of $227,000 from other comprehensive income into earnings
under the caption, "Research and development expense."  As of December 31, 2002,
the  Company  expects  to  reclassify  $119,000  of  net  gains  on  derivative
instruments  from  accumulated  other  comprehensive income to earnings over the
next  12  months  as  a  result of the payment of foreign currency to its German
subsidiaries.

Net Loss Per Share

Basic  and  diluted net loss per share are computed by dividing the net loss for
the  period by the weighted average number of shares of common stock outstanding
during  the  period  adjusted  for  shares  that are subject to repurchase.  The
calculation  of  diluted  net  loss  per  share  excludes potential common stock
because  their effect is antidilutive. Potential common stock consists of common
stock  subject  to  repurchase,  incremental  common  shares  issuable  upon the
exercise  of  stock  options and warrants and shares issuable upon conversion of
the  convertible  promissory  note.

The  following  table  sets  forth potential shares of common stock that are not
included in the computation of diluted net loss per share because to do so would
be  antidilutive  for  the  periods  indicated:

Foreign Currency Translation

Exelixis'  subsidiaries  located  in  Germany  operate  primarily  using  local
functional  currency.  Accordingly,  all  assets  and  liabilities  of  these
subsidiaries  are  translated  using  exchange rates in effect at the end of the
period,  and  revenues and costs are translated using average exchange rates for
the  period.  The  resulting translation adjustments are presented as a separate
component  of  accumulated  other  comprehensive  income.

Stock-based Compensation

The  Company  has  employee  and director stock option plans that are more fully
described  in  Note  10  of the Notes to Consolidated Financial Statements.  The
Company  recognizes  employee stock-based compensation under the intrinsic value
method  of  accounting  as  prescribed by Accounting Principles Board Opinion 25
("APB  25"),  "Accounting  for  Stock  Issued  to  Employees"  and  related
interpretations.  Accordingly,  no  compensation  expense  is  recognized in the
Company's financial statements for the stock options granted to employees, which
had  an exercise price equal to the fair value of the underlying common stock on
the date of grant.  The following table illustrates the effect on net income and
earnings  per  share  if  the  Company  had  applied  the fair value recognition
provisions  of  SFAS  No.  123, "Accounting for Stock-Based Compensation" ("SFAS
123"),  as  amended  by SFAS No. 148, "Accounting for Stock-Based Compensation -
Transition and Disclosure - an amendment of FASB Statement No. 123" ("SFAS 148")

Since  options vest over several years and additional option grants are expected
to  be  made  in future years, the pro forma impact on the results of operations
for  the  three  years  ended December 31, 2002 is not representative of the pro
forma  effects  on  the  results  of  operations  for  future  periods.

For  grants  made  in  2002  and  2001,  the fair value of each option grant was
determined  using  the  Black-Scholes  option  pricing  model with the following
assumptions:  volatility  of  90%  and  88%,  respectively;  0%  dividend yield;
risk-free  interest rate of 3.55% and 4.16%, respectively; and expected lives of
four  years.  For  grants made in 2000 prior to the initial public offering, the
minimum value method was used with the following assumptions: 0% dividend yield;
risk-free  interest rate of 6.51%; and expected lives of five years.  For grants
made  in 2000, subsequent to the initial public offering, the fair value of each
option  grant  was  determined using the Black-Scholes option pricing model with
the  following  assumptions:  volatility  of  87%;  0% dividend yield; risk-free
interest  rate  of  5.70%; and expected lives of four years.  The fair value for
shares  purchased  pursuant  to  the ESPP was determined using the Black-Scholes
option  pricing model with the following assumptions: volatility of 90%, 88% and
87% for 2002, 2001 and 2000, respectively; 0% dividend yield; risk-free interest
rate  of  1.99%,  5.74%  and  6.08%  for  2002, 2001 and 2000, respectively; and
expected  lives  of  six  months.

The  Company  accounts  for  stock options issued to non-employees in accordance
with  the  provisions  of  SFAS  123  and  Emerging  Issues  Task  Force  96-18,
"Accounting  for  Equity Instruments that are Issued to Other Than Employees for
Acquiring,  or  in  Conjunction with, Selling Goods or Services" ("EITF 96-18").
Compensation  expense  for  stock  options  granted  to  non-employees  has been
determined  as the fair value of the consideration received or the fair value of
the  equity  instruments  issued,  whichever  is  more  reliably measured and is
periodically  re-measured  as  the  underlying  options  vest.

NOTE 2 ACQUISITIONS

Genomica Corporation

On  November  19,  2001,  Exelixis  and  Genomica  Corporation  ("Genomica"),  a
bio-informatics  software  company, announced a definitive agreement pursuant to
which Exelixis would acquire Genomica in a stock-for-stock transaction valued at
$110.0  million.  The  transaction  was  structured  as  an  offer  for  100% of
Genomica's  outstanding common stock to be followed by a merger of Genomica with
a  wholly-owned subsidiary of Exelixis.  On December 28, 2001, Exelixis accepted
for  payment  22,911,969 shares of Genomica common stock, or 93.94% of the total
number  of  outstanding shares of common stock of Genomica.  On January 8, 2002,
the  merger  of  Genomica  was  completed.  Upon  effectiveness  of  the merger,
Genomica  became  a wholly-owned subsidiary of Exelixis.  The transaction, which
was  accounted for under the purchase method of accounting in 2001, was effected
through  the  exchange  of  0.28309 of a share of Exelixis common stock for each
outstanding  share  of  Genomica  common  stock.  A  total  of approximately 6.9
million  shares  of Exelixis common stock were issued for all of the outstanding
shares  of  Genomica  common  stock.

The  total  consideration  for the acquisition was approximately $110.0 million,
which  consisted of Exelixis common stock valued at $108.9 million and estimated
Exelixis  transaction  costs of $1.1 million.  As of December 31, 2001, Exelixis
had  issued  only  93.94%  of  the total consideration; accordingly, the Company
recorded  the  value  of  the  remaining  6.06%, or $6.9 million, as a long-term
liability.

The  purchase  price  for  Genomica was allocated to the assets acquired and the
liabilities  assumed  based  on  their  estimated  fair  values  at  the date of
acquisition,  as determined by management based on an independent valuation.  As
a  result  of  this transaction, Exelixis recorded net tangible assets of $106.2
million (including cash and investments of $109.6 million), developed technology
of  $400,000,  which  would  be amortized over three years, and goodwill of $3.4
million.  At the same time, Exelixis recorded goodwill impairment charge of $2.7
million,  which  was expensed in 2001 to operations.  The impairment of goodwill
was  calculated  in  accordance with SFAS 121 by estimating the present value of
future  cash  flows  for  the  ongoing  Genomica licensing business using a risk
adjusted  discount  rate.  The  goodwill  impairment  charge  represented excess
purchase  price  that  Exelixis  viewed  as economically equivalent to financing
costs  for the acquired cash and investments.  Information regarding goodwill is
described  in  further  detail  in Note 6 of the Notes to Consolidated Financial
Statements.

The  following  table  summarizes  the  fair  values  of the assets acquired and
liabilities  assumed  at  the  date  of  the  acquisition  (in  thousands):

Prior  to  the December 28, 2001 acquisition date, Exelixis adopted an exit plan
for  Genomica.  Under  this  exit plan, the Company terminated Genomica's entire
workforce  and  abandoned  its  leased  facilities  in  Boulder,  Colorado  and
Sacramento,  California.  The  estimated costs of the exit plan amounted to $2.9
million and were included as part of the liabilities assumed in the acquisition.

As  of  December 31, 2002, the remaining actions to be taken under the exit plan
consisted primarily of residual payments related to the lease obligation for the
facility  in  Boulder,  Colorado,  which  are  expected  to  continue  until the
termination  of  the  lease  in  2005, unless the facility is subleased earlier.

The  activity impacting the exit plan accrual during the year ended December 31,
2002,  including  changes  in  estimates  made  by management based on available
information,  is  summarized  in  the  table  below  (in  thousands):

In April 2002, Exelixis transferred the Genomica software business to Visualize,
Inc.  ("Visualize")  for  future  consideration of up to $2.4 million in license
fees  and royalty payments.  Pursuant to the terms of the transaction, Visualize
obtained  a  license  with all rights and obligations to third parties currently
licensing the Genomica software, including the sole right to further develop and
license  the software to other third parties.  Royalties that Exelixis receives,
if  any,  will  be  recorded  in  the  period  they  are  earned  as a gain from
discontinued  operations.  In  addition,  Visualize assumed the lease obligation
for  Genomica's  abandoned facility in Sacramento, California.  Exelixis retains
an  internal use license for the software.  As a result of this transaction, the
Company reported the operating results of Genomica and the estimated loss on the
sale  of  Genomica as discontinued operations.  For the period beginning January
1,  2002  to  Genomica's  disposal  in  April 2002, Genomica's operating results
consisted  of  revenues  of  approximately  $58,000  and  an  operating  loss of
approximately $456,000.  The loss on the sale of Genomica includes the write-off
of  remaining  goodwill  of  approximately  $971,000,  partially  offset  by the
reversal  of  Genomica's lease obligation for the Sacramento facility assumed by
Visualize  of  approximately  $176,000.

Artemis Pharmaceuticals GmbH

In May 2001, the Company acquired a majority of the outstanding capital stock of
Artemis  Pharmaceuticals  GmbH  ("Artemis"),  a  privately  held  genetics  and
functional  genomics  company  organized  under  the  laws  of  Germany.  The
transaction,  which  was  accounted for under the purchase method of accounting,
was  effected  through  the  exchange  of  shares  of  Exelixis common stock for
Deutschmark  1.00  of  nominal value of Artemis capital stock, using an exchange
ratio of 4.064 to one. Approximately 1.6 million shares of Exelixis common stock
were issued in exchange for 78% of the outstanding capital stock of Artemis held
by Artemis stockholders. In addition, Exelixis received a call option (the "Call
Option")  from,  and  issued  a  put  option  (the  "Put  Option")  to,  certain
stockholders of Artemis (the "Option Holders") for the issuance of approximately
460,000 shares of Exelixis common stock in exchange for the remaining 22% of the
outstanding capital stock of Artemis held by the Option Holders.  Exelixis could
exercise the Call Option at any time from May 14, 2001 through January 31, 2002,
and  the  Option Holders could exercise their rights under the Put Option at any
time  from  April  1,  2002  through  May 15, 2002.  Exelixis exercised the Call
Option  for 131,674 shares and 329,591 shares in December 2001 and January 2002,
respectively,  which  resulted  in an increase to goodwill of approximately $1.9
million  and  $4.0  million,  respectively.  In  addition, Exelixis issued fully
vested  rights  to  purchase approximately 187,000 additional shares of Exelixis
common stock to Artemis employees in exchange for such employees' vested options
formerly  representing  the  right  to  purchase shares of Artemis capital stock
pursuant  to  the  Artemis  employee  option  program.

As  of  December  31,  2002,  the  total  consideration  for the acquisition was
approximately  $28.2  million,  which  consisted  of  Exelixis  common stock and
options  valued  at  $27.3  million  and estimated Exelixis transaction costs of
$900,000.  Exelixis'  transaction  costs  include  financial  advisory,  legal,
accounting  and  other  fees.

The  total purchase price, which for financial accounting purposes was valued at
$28.2  million, was allocated to the assets acquired and the liabilities assumed
based  on  their estimated fair values at the date of acquisition, as determined
by  management  based  upon  an  independent  valuation.  As  a  result  of this
transaction,  Exelixis  recorded  expense  associated  with  the  purchase  of
in-process research and development of $6.7 million, net tangible assets of $2.8
million  and  intangible  assets  (including  goodwill)  of  $18.7  million, the
majority  of  which  was  being amortized over 15 years until December 31, 2001.

The  valuation  of  the  purchased  in-process  research and development of $6.7
million  was based upon the results of an independent valuation using the income
approach  for  each of the three significant in-process projects. The in-process
projects relate primarily to the development of technologies that use vertebrate
genetic  model  organisms,  zebrafish  and  mice,  to  identify and functionally
validate  novel  genes  in  vivo.  These  genes  can  be used as novel screening
targets  or  as  the  basis for secreted proteins in clinically and commercially
relevant  diseases.  The in-process projects have been abandoned or are expected
to  be  completed  over  approximately  the  next two years. The income approach
estimates  the  value  of each acquired in-process project based on its expected
future  cash  flows.  The  valuation analysis considered the contribution of the
core  technology as well as the percent complete of each in-process research and
development  project.  The  expected  present value of the cash flows associated
with  the in-process research and development projects was computed using a risk
adjusted  rate  of  return  of  30%,  which  is considered commensurate with the
overall  risk  and  percent  complete  of the in-process projects. The purchased
in-process  research  and  development  was  not  considered  to  have  reached
technological  feasibility,  and  it  has  no  alternative  future  use,  and
accordingly,  it  was  recorded  as  a  component  of  operating  expense.

The  revenues,  expenses,  cash  flows  and  other  assumptions  underlying  the
estimated fair value of the acquired in-process research and development involve
significant risks and uncertainties. The risks and uncertainties associated with
completing  the acquired in-process projects include the ability to reach future
research  milestones  since  the  technologies being developed are unproven, the
ability to retain key personal, the ability to obtain licenses to key technology
and  the  ability  to  avoid infringing on patents and propriety rights of third
parties.

Agritope, Inc.

In  December  2000,  Exelixis  completed  its  acquisition  of  Agritope,  Inc.
("Agritope").  As  a  result  of the acquisition, Agritope became a wholly-owned
subsidiary  of  Exelixis,  and was subsequently renamed Exelixis Plant Sciences,
Inc.  ("Exelixis  Plant  Sciences").  The  transaction,  which was accounted for
under  the  purchase  method of accounting, was effected through the exchange of
0.35  of a share of Exelixis common stock for each outstanding share of Agritope
capital  stock.  Approximately  1.7 million shares of Exelixis common stock were
issued  in  connection  with  the  transaction.  In  addition,  unexpired  and
unexercised  options  and  warrants to purchase shares of Agritope capital stock
were  assumed  by  Exelixis pursuant to the transaction and converted into fully
vested options and warrants to purchase approximately 880,000 shares of Exelixis
common  stock.

The  total  consideration  for  the acquisition was approximately $93.5 million,
which  consists  of  Exelixis common stock, options and warrants valued at $92.2
million  and  estimated  Exelixis  transaction  costs of $1.3 million. Exelixis'
transaction  costs include financial advisory, legal, accounting and other fees.

The  purchase  price  for  Agritope, which for financial accounting purposes was
valued  at  $93.5  million,  was  allocated  to  the  assets  acquired  and  the
liabilities  assumed  based  on  their  estimated  fair  values  at  the date of
acquisition,  as  determined  by  an independent valuation.  As a result of this
transaction,  Exelixis  recorded  expense  associated  with  the  purchase  of
in-process  research  and development of $38.1 million, net tangible liabilities
of $3.6 million and intangible assets (including goodwill) of $58.9 million, the
majority  of  which  was  being amortized over 15 years until December 31, 2001.

The  valuation  of  the  purchased  in-process research and development of $38.1
million  was based upon the results of an independent valuation using the income
approach  for  each  of  the  ten  projects in process.  The in-process projects
relate  primarily  to the development of disease and insect resistant fruits and
vegetables  and  have  been  abandoned  or  are  expected  to  be completed over
approximately  the next three and one-half years.  The income approach estimates
the  value of each acquired in-process project based on its expected future cash
flows. The valuation analysis considered the contribution of the core technology
as  well  as  the  percent  complete of each in-process research and development
project.  The  expected  present  value  of  the  cash flows associated with the
in-process  research and development projects was computed using a risk adjusted
rate  of  return  of 35%, which is considered commensurate with the overall risk
and  percent  complete  of the in-process projects. The purchased technology was
not  considered  to  have  reached  technological  feasibility,  and  it  has no
alternative  future  use,  and  accordingly,  it  was  recorded  as  a component
operating  expense.

The  revenues,  expenses,  cash  flows  and  other  assumptions  underlying  the
estimated fair value of the acquired in-process research and development involve
significant risks and uncertainties. The risks and uncertainties associated with
completing  the  acquired  in-process  projects  include obtaining the necessary
regulatory  approvals  in  a  timely  manner  and being able to successfully and
profitably  produce,  distribute  and  sell  products.

The Company acquired Vinifera, Inc. ("Vinifera") in connection with the purchase
of Agritope (the parent company of Vinifera) in 2000.  Vinifera was organized as
a  majority-owned  subsidiary  and  was  engaged  in  the grape vine propagation
business.  On  the date of acquisition, Exelixis committed to a plan to sell the
Vinifera  operations  because  this  business  did  not  fit  with the strategic
objectives of the Company.  On March 31, 2001, the Company reduced its ownership
interest  in  Vinifera from 57% to 19% by selling 3.0 million shares of Vinifera
common  stock  back  to  Vinifera  in consideration for $2.1 million in interest
bearing  promissory notes. As a result of the sale of Vinifera common stock back
to  Vinifera, Exelixis deconsolidated Vinifera, excluded its share of Vinifera's
operating  losses  for  the  first  quarter of 2001 of $275,000 and recorded the
following  amounts  as an adjustment to goodwill recorded in connection with the
acquisition  of  Agritope:  a  write-down  of  the  value  of acquired developed
technology  attributable  to  Vinifera  of  $435,000, a gain on sale of Vinifera
shares  of  $590,000  and  a  promissory  note  reserve  of $1,700,000.  The net
adjustment  was  an  increase  to goodwill in the amount of $675,000.  Beginning
April  1,  2001,  the Company accounted for its remaining investment in Vinifera
using  the  cost  method.

As of December 31, 2001, the Company reserved for 100% of these promissory notes
due  to  risks  associated with collection.  Due to a significant decline in the
operating  performance of Vinifera, in December 2001, the Company wrote down its
remaining cost-basis investment in Vinifera to zero.  Vinifera ceased operations
in  2002.

In connection with the Agritope acquisition, Exelixis also acquired interests in
Agrinomics  LLC  ("Agrinomics"), which is a 50% owned subsidiary that conducts a
gene discovery program, and Superior Tomato Associates, LLC ("Superior Tomato"),
which was a 66-2/3% owned subsidiary formed to develop and market longer-lasting
tomatoes.  The  Company dissolved Superior Tomato during 2001, which resulted in
no material impact to its financial results.  Agrinomics continues in existence.

NOTE 3 RESEARCH AND COLLABORATION AGREEMENTS

Bayer

In  May  1998,  the  Company  entered  into  a  six-year  research collaboration
agreement  with  Bayer  AG (including its affiliates, "Bayer") to identify novel
screening  targets  for  the  development  of  new  pesticides  for  use in crop
protection.  The Company provided research services directed towards identifying
and  investigating molecular targets in insects and nematodes that may be useful
in  developing  and  commercializing  pesticide products. The Company received a
$1.2  million  license fee upon execution of the agreement that was deferred and
will  be  recognized  as  revenue  over  the  term  of  the  agreement.

In December 1999, the Company significantly expanded its relationship with Bayer
by  forming  a  joint  venture  in  the form of a new limited liability company,
Genoptera  LLC  ("Genoptera").  Under  the  terms  of  the  Genoptera  operating
agreement,  Bayer  provides 100% of the capital necessary to fund the operations
of  Genoptera  and  has  the  ability to control the entity with a 60% ownership
interest.  The  Company  owns the other 40% interest in Genoptera without making
any  capital  contribution  and  reports  its  investment in Genoptera using the
equity  method of accounting. Bayer's initial capital contributions to Genoptera
were  $10.0  million  in January 2000 and another $10.0 million in January 2001.
Bayer  is  required to also contribute cash to Genoptera in amounts necessary to
fund  its  ongoing  operating  expenses.  Genoptera  has  incurred  losses since
inception.  Since  the carrying value of this investment is zero and there is no
obligation to fund future losses, Exelixis has not recorded equity method losses
to  date  for  Genoptera.

In  January  2000,  the  Company,  Bayer and Genoptera entered into an exclusive
eight-year research collaboration agreement, which superceded the 1998 agreement
discussed  above.  The  Company  is  required to provide Genoptera with expanded
research  services  focused  on developing insecticides and nematicides for crop
protection.  Under  the terms of the collaboration agreement, Genoptera paid the
Company a $10.0 million license fee and a $10.0 million research commitment fee.
One-half  of these fees were received in January 2000, and the remaining amounts
were  received  in  January 2001. Additionally, Genoptera is required to pay the
Company  approximately $10.0 million in annual research funding. The Company can
earn  additional payments under the collaboration agreement upon the achievement
of certain milestones. The Company can also earn royalties on the future sale by
Bayer  of  pesticide  products incorporating compounds developed against targets
and  assays  under the agreement. The agreement also provides Bayer an exclusive
royalty-free  option  to use certain technology developed under the agreement in
the  development of fungicides and herbicides. To the extent permitted under the
collaboration  agreement,  if the Company were to develop and sell certain human
health  or  agrochemical products that incorporate compounds developed under the
agreement,  it  would  be  obligated  to  pay  royalties  to  Genoptera. No such
activities  are  expected  for  the  foreseeable  future.

Bristol-Myers  Squibb

In September 1999, the Company entered into a three-year research and technology
transfer  agreement with Bristol-Myers Squibb Company ("Bristol-Myers Squibb" or
"BMS") to identify the mechanism of action ("MOA") of compounds delivered to the
Company  by BMS.  In July 2002, the agreement was extended for an additional two
years.  BMS agreed to pay the Company a $250,000 technology access fee, which is
being  recognized  as revenue over the term of the agreement. Under the terms of
the  agreement, the Company is entitled to receive research funding ranging from
$1.3  million in the first year up to as much as $2.5 million annually in future
years.  The  Company  can  also earn additional amounts under the agreement upon
the  achievement  of  certain milestones as well as earn royalties on the future
sale  by  BMS  of  human  products  incorporating  compounds developed under the
agreement.  The agreement also includes technology transfer and licensing terms,
which  call  for  BMS  and  the  Company  to  license  and  share  certain  core
technologies  in  genomics  and  lead  optimization.

In  July  2001, the Company and BMS entered into a collaboration involving three
agreements:  (a)  a  Stock  Purchase  Agreement;  (b)  a  Cancer  Collaboration
Agreement;  and  (c)  a License Agreement. Under the terms of the collaboration,
BMS (i) purchased 600,600 shares of Exelixis common stock in a private placement
at  a  purchase  price  of  $33.30  per  share, for cash proceeds to Exelixis of
approximately  $20.0 million; (ii) agreed to pay Exelixis a $5.0 million upfront
license  fee and provide Exelixis with $3.0 million per year in research funding
for  a  minimum  of  three  years;  and  (iii)  granted to Exelixis a worldwide,
fully-paid,  exclusive  license to an analogue to Rebeccamycin developed by BMS,
which  is  currently in Phase I and Phase II clinical trials for cancer.  Due to
risk  and  uncertainties  with  Rebeccamycin,  and  because the analogue had not
reached  technological  feasibility and has no alternative use, the analogue was
assigned  no  value  for  financial  reporting purposes.  Exelixis has agreed to
provide  BMS  with exclusive rights to certain potential small molecule compound
drug targets in cancer identified during the term of the research collaboration.
The  premium in excess of fair market value of $10.0 million paid for the common
stock  purchased by BMS is being accounted for similar to an upfront license fee
and  is  being  recognized  ratably  over  the  life  of  the  contract.

SmithKlineBeecham  Corporation

In  October 2002, Exelixis and SmithKlineBeecham Corporation ("GSK") established
a  collaboration  to  discover  and  develop  novel therapeutics in the areas of
vascular biology, inflammatory disease and oncology.  The collaboration involved
three agreements: (a) a Product Development and Commercialization Agreement; (b)
a  Stock  Purchase  and  Stock  Issuance  Agreement; and (c) a Loan and Security
Agreement.  Under  the  terms  of  the Product Development and Commercialization
Agreement,  GSK  has  paid the Company $30.0 million in an upfront fee and $10.0
million  in  annual  research  funding,  and  has  agreed to pay a minimum of an
additional  $80.0 million in research and development funding over the first six
years  of  the  collaboration.

Under  the  terms  of  the  Stock  Purchase  and  Stock  Issuance Agreement, GSK
purchased two million shares of Exelixis' common stock in a private placement at
a  purchase  price  of  $7.00  per  share,  which  represented  a  premium  of
approximately  100%  to the stock price on the effective date of the agreements.
The  Company  received  cash  proceeds  of  approximately  $14.0 million for the
purchase  of  these  shares.  Exelixis  has the option to sell additional common
shares  to  GSK  in  the  future.

Under  the  Loan  and  Security Agreement, GSK provided a loan facility of up to
$85.0  million for use in the Company's efforts under the collaboration, and the
Company  borrowed  $25.0 million under that agreement in December 2002. All loan
amounts  bear  interest  at  a  rate  of  4%  per  annum  and are secured by the
intellectual  property, technology and equipment created or utilized pursuant to
the  collaboration.  Principal  and accrued interest become due in installments,
beginning  on  or  about  the sixth anniversary of the collaboration, unless the
collaboration  is  earlier  terminated  by  GSK.  Repayment of all or any of the
amounts  advanced  to  the  Company  under  this agreement may, at the Company's
election,  be  in  the  form  of  Exelixis'  common  stock,  subject  to certain
conditions.

The  upfront  fee  and  the  premium  portion  of  the equity purchase have been
deferred  and will be recognized as revenue over the development term.  Exelixis
may  also  receive  clinical  and developmental payments based on the number and
timing  of  compounds  reaching  specified  milestones.  Based  on the continued
successful  development  of  these  compounds,  these  payments could range from
$219.0 million to $369.0 million, through the compounds' commercialization.  Two
years  from the start of the collaboration, GSK and Exelixis may elect to expand
the  collaboration,  and  under  this option, Exelixis' milestone payments could
double,  and  the  development  funding  and  the  loan  facility  would also be
significantly  expanded.

Dow  AgroSciences

In  July 2000, the Company entered into a three-year research collaboration with
Dow  AgroSciences LLC ("Dow AgroSciences") to identify the MOA of herbicides and
fungicides  delivered  to it under this agreement.  The identity and function of
these  compounds  are  not  known  to  the  Company  prior  to  their  delivery.

Under this agreement, the Company receives access to a collection of proprietary
compounds  from  Dow  AgroSciences  that  may  be  useful in the Company's human
therapeutic  drug  discovery  programs.

The Company is required to identify and validate targets and format assays to be
used  by  Dow  AgroSciences to develop new classes of fungicides and herbicides.
Dow  AgroSciences will pay the Company research support fees, milestone payments
and royalties based on achievements in the research and commercialization of any
resultant  new  products.

Protein  Design  Labs

On  May 22, 2001, the Company and Protein Design Labs, Inc. ("PDL") entered into
a  collaboration to discover and develop humanized antibodies for the diagnosis,
prevention  and  treatment  of  cancer. The collaboration will utilize Exelixis'
model  organism  genetics  technology  for the identification of new cancer drug
targets  and  PDL's  antibody  and  clinical development expertise to create and
develop  new  antibody drug candidates. PDL is required to provide Exelixis with
$4.0  million  in  annual  research  funding until June 2003 and has purchased a
$30.0  million  convertible  note.  The  note  bears  interest at 5.75%, and the
interest  thereon  is  payable annually. The note is convertible at PDL's option
any  time  after  the  first  anniversary  of  the  note's issuance. The note is
convertible  into Exelixis common stock at a conversion price per share equal to
the  lower  of  (i) $28.175 or (ii) 110% of the Fair Market Value (as defined in
the  note)  of  a  share  of  Exelixis  common  stock at the time of conversion.

Agrinomics

In  July  1999, Agritope and Aventis CropScience USA. LP ("Aventis CropScience,"
now  Bayer CropScience LP, "Bayer CropScience") formed Agrinomics LLC to conduct
a  research,  development  and  commercialization  program  in  the  field  of
agricultural  functional  genomics.  As a result of the Company's acquisition of
Agritope, the Company owns a 50% interest in Agrinomics, while Bayer CropScience
owns  the  remaining 50% interest.  Bayer CropScience has agreed to make capital
contributions  to  Agrinomics  in  cash  totaling $20.0 million over a five-year
period,  of  which  $3.0  million  and $4.0 million were contributed in 2002 and
2000,  respectively.  There  were  no  capital  contributions  made  by  Bayer
CropScience  to Agrinomics in 2001.  Agritope contributed certain technology and
a  collection  of seeds generated using such technology.  In connection with the
Company's acquisition of Agritope, no portion of the purchase price was assigned
to  Agrinomics.  Although  the Company is required to account for its investment
in Agrinomics under the equity method, the Company does not expect to include in
its  consolidated  financial statements its proportionate share of the losses of
Agrinomics  until  such  time,  if  ever,  that  the  Company  makes  a  capital
contribution  to  Agrinomics.  There  is  no requirement for the Company to make
capital  contributions  to  Agrinomics.

In December 2002, Agrinomics established an alliance to enhance seed oil content
in  commercially  valuable crops with Renessen LLC.  Renessen is a joint venture
between  Monsanto  Company  and  Cargill,  Inc.  The  collaboration  combines
Agrinomics'  technological  leadership  in  agricultural  functional  genomics,
high-throughput  gene  screening  and  seed  trait  identification, developed at
Exelixis  Plant Sciences, with Renessen's global expertise in quality trait crop
development and commercialization, with the goal of accelerating the development
of  novel  proprietary  crops  with  improved  seed  composition  traits.  This
collaboration  leverages  the unique capabilities of Agrinomics' powerful ACTTAG
gene  activation  and  selection platform to rapidly discover and validate genes
that  can  optimize  important  seed  traits in order to increase the commercial
value  of  many  of  the world's most significant agricultural crops.  Under the
terms  of  the  collaboration,  Renessen  will provide Agrinomics with committed
annual  research  funding  ranging  from $1.3 million in the first year up to as
much  as  $2.0 million annually in future years, in addition to payments for the
selection  of  genes  and  other  product  options.  Agrinomics  can  also  earn
additional  amounts  under  the  agreement  upon  the  achievement  of  certain
milestones, as well as royalties on commercialized products that may emerge from
the  collaboration.  In  addition, Renessen will contribute research and product
development capabilities in taking gene candidates identified by Agrinomics into
crop  products  that  include  leading  commercial  germplasm.

Pharmacia

In  February  1999,  the Company entered into a research collaboration agreement
with  Pharmacia Corporation ("Pharmacia") focused on the identification of novel
targets  that may be useful in the development of pharmaceutical products in the
areas of Alzheimer's disease and metabolic syndrome. Pharmacia agreed to pay the
Company a $5.0 million non-refundable license fee, which was being recognized as
revenue  over  the  term  of the agreement. Under the terms of the agreement, as
expanded  and  amended  in October 1999, the Company also received an obligation
from  Pharmacia  to  provide future research funding.  In July 2001, the Company
announced  the  reacquisition,  effective February 2002, of future rights to the
research  programs.  Pharmacia  retained  rights  to  targets under the existing
agreement  selected  prior  to the reacquisition date, subject to the payment of
milestones  for  certain  of  those  targets  selected  and royalties for future
development  of products against or using those targets.  Pharmacia will have no
other  obligations to make payments to the Company, including approximately $9.0
million  in  annual  funding  that  would  have  otherwise  been  payable for an
additional  two  years if the Company had not elected to reacquire rights to the
research.  As  a  result  of  this  transaction,  revenue recognition of upfront
license  fees  and milestone payments was accelerated over the remaining term of
the  agreement.

In  connection  with  entering  into the February 1999 agreement, Pharmacia also
purchased  1,875,000  shares  of  Exelixis Series D preferred stock at $3.00 per
share,  resulting  in net cash proceeds to the Company of $7.5 million. Further,
Pharmacia loaned the Company $7.5 million in exchange for a non-interest bearing
convertible  promissory note. The convertible promissory note was converted into
an  aggregate  of  480,769  shares  of common stock of the Company in July 2000.

Compound Collaborations

The  Company entered into collaboration agreements with Cytokinetics, Inc., Elan
Pharmaceuticals,  Inc.,  Schering-Plough Research Institute, Inc. and Scios Inc.
in  2001 and Merck & Co., Inc. in 2002, to jointly design custom high-throughput
screening  compound  libraries  that Exelixis will synthesize and qualify.  Each
company  is  required to pay Exelixis a per-compound fee and has paid an upfront
technology  access  fee  that  is  creditable  towards  the  future  purchase of
compounds.  The  upfront  fees  are  initially  deferred.  Revenues  under these
collaboration  agreements  will  generally  be  recognized  upon delivery of the
accepted  compounds.  Each  party retains the rights to use the compounds in its
own  unique  drug discovery programs and in its collaborative efforts with third
parties.

NOTE 4 RELATED PARTY TRANSACTIONS

The  Company  had outstanding loans aggregating $904,000 and $937,000 to certain
officers  and  employees  at December 31, 2002 and 2001, respectively. The notes
are  general  recourse  or  collateralized by certain real property assets, bear
interest  at  rates  ranging from 4.6% to 7.0% and have maturities through 2006.
The principal plus accrued interest will be forgiven at various rates over three
to  four  years  from  the  employees'  date  of employment with Exelixis. If an
employee  leaves Exelixis, all unpaid and unforgiven principal and interest will
be  due  and  payable  within  60  days.

As of December 31, 2002, the Company also had outstanding loans aggregating $1.2
million  to  its  stockholders.  The  loans  were  issued  to  enable  certain
non-officer  employees  to  purchase  stock  pursuant  to  their  employee stock
options.  The  loans  bear  interest  at  rates  ranging from 6.13% to 6.50% and
mature  at  various  times  through  February  2004.

For  the  years  ended, December 31, 2002, 2001 and 2000, the Company recognized
revenues  of $13.6 million, $13.1 million and $13.2 million, respectively, under
a  collaboration  agreement  with Bayer through the Company's joint venture with
Genoptera.

For the years ended, December 31, 2001 and 2000, the Company recognized revenues
of $3.8 million and $237,000, respectively, under a collaboration agreement with
Aventis CropScience through the Company's joint venture with Agrinomics.  During
2002,  Bayer  completed  the  acquisition  of  Aventis  S.A.,  including Aventis
CropScience.  As  a  result, Bayer assumed Aventis' 50% ownership of Agrinomics.
The  Company  recognized  revenues  of  $3.8  million under the Agrinomics joint
venture  for  the  year  ended,  December  31,  2002.

and  $3.3  million  at  December  31,  2002,  2001  and  2000, respectively. The
equipment under the capital leases collateralizes the related lease obligations.

NOTE 6 GOODWILL AND OTHER ACQUIRED INTANGIBLES

On  January  1,  2002,  the  Company  adopted  SFAS No. 142, "Goodwill and Other
Intangible  Assets"  ("SFAS  142"), which addresses the financial accounting and
reporting standards for goodwill and other intangible assets subsequent to their
acquisition.  This  accounting  standard  requires  that  goodwill  no longer be
amortized,  and  instead,  be  tested  for  impairment  on  a  periodic  basis.

In  accordance  with  SFAS  142,  the  Company  discontinued the amortization of
goodwill  effective  January  1, 2002. In addition, the Company re-characterized
any unamortized acquired assembled workforce as goodwill because it is no longer
defined  as  an  acquired  intangible  asset  under  SFAS  No.  141,  "Business
Combinations".  Accordingly,  no goodwill or acquired workforce amortization was
recognized  during  the year ended December 31, 2002. The provisions of SFAS 142
also  required the completion of a transitional impairment test within 12 months
of  adoption,  with  any  impairment treated as a cumulative effect of change in
accounting  principle.  During  the first quarter of 2002, the Company completed
the transitional impairment test, which did not result in impairment of recorded
goodwill.

The  Company adopted an annual goodwill impairment test date as of the beginning
of  the  fourth  quarter  of  2002.   Following  this approach, the Company will
monitor  asset-carrying  values  as of October 1, assess if there is a potential
impairment and complete the measurement of impairment, if required.  The Company
will  perform  the  impairment  measurement  procedures  under  SFAS  142  if it
determines  that  a  potential  impairment  of  goodwill  exists.

The  Company  completed  the annual impairment test as of October 1, 2002, which
did  not  result  in  impairment  of  recorded  goodwill.

NOTE 7 RESTRUCTURING CHARGE

In  November  2002,  the  Company  implemented  a  restructuring  plan.  This
restructuring  plan  was  designed  to facilitate the Company's evolution into a
fully  integrated  drug  discovery  company  by reallocating resources to permit
greater  focus  on  building  the  Company's  expanding portfolio of development
programs.  The  restructuring  resulted  in  a  reduction  in  workforce  of  40
employees,  primarily  from the Company's U.S. research operations. Accordingly,
the Company has recorded a restructuring charge in the fourth quarter of 2002 of
$708,000,  consisting  primarily  of  involuntary  termination  benefits.  As of
December  31,  2002, substantially all amounts under the restructuring have been
paid.

NOTE 8 DEBT

Under  the  Loan  and  Security  Agreement  executed  in connection with the GSK
collaboration,  GSK  provided  a loan facility of up to $85.0 million for use in
the  Company's  efforts  under  the  collaboration.  The  Company borrowed $25.0
million under that agreement in December 2002. All loan amounts bear interest at
a  rate of 4% per annum and are secured by the intellectual property, technology
and  equipment created or utilized pursuant to the collaboration.  Principal and
accrued  interest  become  due  in installments, beginning on or about the sixth
anniversary of the collaboration, unless the collaboration is earlier terminated
by  GSK.  Repayment  of  all or any of the amounts advanced to the Company under
this  agreement  may,  at  the  Company's  election, be in the form of Exelixis'
common  stock,  subject  to  certain  conditions.

In  May 2002, the Company entered into a loan and security agreement with a bank
for an equipment line of credit of up to $16.0 million with a drawdown period of
one  year.  Each  draw on the line of credit has a payment term of 48 months and
bears  interest at the bank's published prime rate (4.25% at December 31, 2002).
At  December 31, 2002, approximately $5.1 million was outstanding under the line
of credit, and $10.9 million remained available on the line of credit.  Pursuant
to  the terms of the line of credit, the Company is required to maintain a first
priority security interest in the form of a deposit or securities account at the
bank equal to 110% of the outstanding obligation under the line of credit.  This
collateral account is managed in accordance with the Company's investment policy
and  is  restricted  as  to withdrawal.  As of December 31, 2002, the collateral
account  had  a  cash  balance  of  approximately  $5.8 million, and the Company
recorded  this  amount  in  the  balance  sheet  as  restricted  cash.

In connection with the acquisition of Artemis in May 2001, the Company assumed a
loan  agreement with the Federal Republic of Germany.  The $254,000 loan, all of
which  is  outstanding at December 31, 2002, requires the entire principal to be
paid in one payment in January of 2004.  The loan has an interest rate of 1% per
annum  to  be  paid  quarterly.

In  May  2001, the Company issued a $30.0 million convertible promissory note to
PDL  in  connection with a collaboration agreement (see Note 3).  The note bears
interest  at  5.75%,  payable annually. The note, which matures in July 2006, is
convertible  at  PDL's  option any time after the first anniversary of the note.
The  note  is  convertible  into Exelixis common stock at a conversion price per
share  equal  to  the lower of (i) $28.175 or (ii) 110% of the Fair Market Value
(as  defined  in  the  note)  of a share of Exelixis common stock at the time of
conversion.  The full amount of the note remained outstanding as of December 31,
2002  and  2001.

In  connection  with  the  acquisition of MetaXen in September 1999, the Company
assumed a loan agreement that provided for the financing of equipment purchases.
Borrowings under the agreement are collateralized by the assets financed and are
subject  to  repayment  over  36  to  48  months, depending on the type of asset
financed. Borrowings under the agreement bear interest at the U.S. Treasury note
rate plus a number of basis points determined by the type of asset financed.  As
of  December  31,  2001, there was approximately $143,000 outstanding under this
loan  agreement, which was paid in full during the year ended December 31, 2002.

In  July  1998,  the  Company  entered  into a $5.0 million equipment and tenant
improvements  lending  agreement of which the drawdown period expired in January
2000.  As  of  December  31, 2002 and 2001, there was approximately $426,000 and
$1.5 million, respectively, outstanding under the lending agreement.  Borrowings
under the agreement have a payment term of 42 months, bear interest at 14.5% per
year  and  are  collateralized  by  the  financed  equipment.

Aggregate  future  principal  payments of the convertible promissory note, notes
payable and bank obligations at December 31, 2002 are as follows (in thousands):

NOTE 9 COMMON STOCK AND WARRANTS

Initial Public Offering

On  April 14, 2000, the Company completed an initial public offering in which it
sold  9,100,000 shares of common stock at $13.00 per share for net cash proceeds
of  approximately $108.0 million, net of underwriting discounts, commissions and
other  offering  costs.  Upon  the  closing  of  the offering, all the Company's
mandatorily  redeemable  convertible  preferred  stock converted into 22,877,656
shares  of  common  stock.  After the offering, the Company's authorized capital
consisted  of  100,000,000  shares  of  common  stock,  $0.001  par  value,  and
10,000,000  shares  of  preferred  stock,  $0.001 par value. On May 1, 2000, the
underwriters  exercised  the  over-allotment  option  to  purchase an additional
1,365,000 shares, resulting in net cash proceeds of approximately $16.5 million.

Stock Repurchase Agreements

Under  the  terms  of  the Company's stock option plans, options are exercisable
when  granted,  and,  if exercised, the related shares are subject to repurchase
upon  termination  of  employment.  Repurchase  rights  lapse  over  the vesting
periods, which are generally four years. Should the employment of the holders of
common  stock  subject  to  repurchase  terminate  prior  to full vesting of the
outstanding  shares,  the  Company may repurchase all unvested shares at a price
per  share  equal to the original exercise price. At December 31, 2002 and 2001,
378,471  and  1,253,226  shares,  respectively,  were subject to such repurchase
terms.

Warrants

Historically,  the  Company  has  granted warrants to purchase shares of capital
stock  to  certain  preferred  stockholders and third parties in connection with
financing  and operating lease arrangements. In addition, in connection with the
Agritope acquisition (refer to Note 2), the Company assumed warrants to purchase
239,167  shares  of  Company  common stock. All of the Agritope warrants expired
unexercised  on  December  31,  2001.

At  December  31,  2002,  the  following  warrants to purchase common stock were
outstanding  and  exercisable:



  Number    Exercise Price          Date            Expiration
of Shares     per Share            Issued              Date

=========


The Company determines the fair value of warrants issued using the Black-Scholes
option  pricing  model. Prior to 1999, the fair value of warrants issued was not
material,  and  accordingly,  no  value  has been ascribed to them for financial
reporting  purposes.

The  Company  determined  the  fair  value  of  the warrants issued during 1999,
related  to  a building lease, using the Black-Scholes option pricing model with
the  following  assumptions:  expected  life  of  five years; a weighted average
risk-free  interest rate of 6.1%; expected dividend yield of zero; volatility of
70%;  and a deemed value of the common stock of $5.71 per share.  The fair value
of  the warrants of $391,000 has been capitalized and is being amortized as rent
expense  over  the  term  of  the  lease.

The  Company  determined  the  fair  value  of  the warrants issued during 2000,
related  to a building lease, using the Black-Scholes option pricing model using
the  following  assumptions:  expected  life  of  five years; a weighted average
risk-free interest rate of 6.38%; expected dividend yield of zero; volatility of
70%; and a deemed value of the common stock of $11.00 per share.  The fair value
of  the warrants of $518,000 has been capitalized and is being amortized as rent
expense  over  the  term  of  the  lease.

Reserved Shares

At  December  31,  2002,  the  Company  had approximately 19.1 million shares of
common  stock  reserved  for  future issuance related to its stock plans, 401(k)
plan,  convertible  note  and  loan  and  the  exercise of outstanding warrants.

NOTE 10 EMPLOYEE BENEFIT PLANS

Stock Based Benefit Plans

Stock  Option  Plans.  In  January  1995, the Company adopted the 1994 Employee,
Director and Consultant Stock Option Plan ("1994 Plan").  The 1994 Plan provides
for  the  issuance  of  incentive stock options, non-qualified stock options and
stock  purchase  rights  to key employees, directors, consultants and members of
the  Scientific  Advisory Board ("SAB").  In September 1997, the Company adopted
the  1997  Equity  Incentive  Plan  ("1997  Plan").  The  1997  Plan  amends and
supercedes  the 1994 Plan.  In January 2000, the Company adopted the 2000 Equity
Incentive  Plan  ("2000  Plan")  to  replace the 1997 Plan. A total of 3,000,000
shares of Exelixis common stock were initially authorized for issuance under the
2000  Plan.  On  the  last day of each year for ten years, starting in 2000, the
share reserve will automatically be increased by a number of shares equal to the
greater  of: 5% of the Company's outstanding shares on a fully-diluted basis; or
that number of shares subject to stock awards granted under the 2000 Plan during
the  prior  12-month  period.

The Board of Directors or a designated Committee of the Board is responsible for
administration  of  the Company's employee stock option plans and determines the
term,  exercise  price and vesting terms of each option. Incentive stock options
may  be  granted  at an exercise price per share at least equal to the estimated
fair  value per underlying common share on the date of grant (not less than 110%
of  the  estimated  fair  value  in  the case of holders of more than 10% of the
Company's  voting  stock).  Options  granted  under  the 1997 and 2000 Plans are
exercisable  when  granted and generally expire ten years from the date of grant
(five  years  for incentive stock options granted to holders of more than 10% of
the  Company's  voting  stock).

In  January  2000,  the  Company adopted the 2000 Non-Employees Directors' Stock
Option  Plan  ("Director  Plan").  The  Director Plan provides for the automatic
grant of options to purchase shares of common stock to non-employee directors. A
total  of 500,000 shares of the Company's common stock were initially authorized
for  issuance  under  the  Director  Plan.  On the last day of each year for ten
years,  starting in 2000, the share reserve will automatically be increased by a
number  of  shares  equal  to the greater of: 0.75% of the Company's outstanding
shares  on  a  fully-diluted  basis; or that number of shares subject to options
granted  under  the  Director Plan during the prior 12-month period. Each person
who  is  a non-employee director will automatically receive an initial grant for
25,000 shares. The initial grant is exercisable immediately but will vest at the
rate of 25% of the shares on the first anniversary of the grant date and monthly
thereafter over the next three years.  In addition, on the day after each annual
meeting  of  the  Exelixis  stockholders,  each  non-employee  director  will
automatically  receive  an  annual  grant for 5,000 shares. This annual grant is
exercisable  immediately  but  will  vest  monthly  over  the  following  year.

In  connection  with  the  acquisition of Agritope in December 2000, the Company
assumed  all  the  options  granted and outstanding to consultants and employees
under  the Agritope, Inc. 1997 Stock Award Plan. Each outstanding Agritope stock
option  was  converted  into  the  right to purchase the number of shares of the
Company's common stock as determined using the applicable exchange ratio of 0.35
(refer to Note 2).  All other terms and conditions of the Agritope stock options
did  not  change  and  such options will operate in accordance with their terms.

During  April  2001,  Exelixis  granted approximately 545,000 supplemental stock
options ("Supplemental Options") under the 2000 Equity Incentive Plan to certain
employees (excluding officers and directors) who had stock options with exercise
prices  greater  than $16.00 per share under the 2000 Equity Incentive Plan. The
number  of  Supplemental  Options  granted was equal to 50% of the corresponding
original grant held by each employee.  The Supplemental Options have an exercise
price of $16.00, vest monthly over a two-year period beginning April 1, 2001 and
have  a  27-month  term. The vesting on the corresponding original stock options
was  halted and will resume in April 2003 following the completion of vesting of
the  Supplemental  Options.  This new grant constitutes a synthetic repricing as
defined  in  Financial  Accounting Standards Board Interpretation Number ("FIN")
44, "Accounting for Certain Transactions Involving Stock Compensation," and will
result  in  certain  options  being  reported  using the variable plan method of
accounting for stock compensation expense until they are exercised, forfeited or
expire.  For  the  years  ended  December  31,  2002  and  2001,  the cumulative
compensation  expense  recorded  for  the Supplemental Options was approximately
($242,000)  and  $246,000,  respectively.

A  summary  of  all  option  activity  is  presented  below:

                                    ==============


At  December 31, 2002, a total of 378,471 shares of common stock purchased under
the  1994,  1997  and  2000 Plans were subject to repurchase by the Company at a
weighted average price of $0.92 per share.  The weighted-average grant date fair
value of options granted during the years ended December 31, 2002, 2001 and 2000
was  $7.38,  $8.86  and  $10.01  per  share,  respectively.

Deferred  Stock  Compensation.  During  the  period from January 1, 1999 through
December  31,  2002,  the  Company  recorded  $29.9  million  of  deferred stock
compensation  related  to  stock options granted to consultants and employees in
accordance  with  APB  25,  SFAS  123  and  EITF  96-18.  For options granted to
consultants,  the  Company  determined  the  fair value of the options using the
Black-Scholes  option  pricing  model  with  the  following  weighted-average
assumptions:  (a)  no dividends; (b) expected volatility of 88%, 87% and 79% for
2002,  2001  and  2000,  respectively;  (c) risk-free interest rate of 4.16% for
2002,  5.70% for 2001 and 5.75% for 2000; and (d) expected lives of five and ten
years  for 2002, ten years for 2001 and four years for 2000.  Stock compensation
expense  is  being  recognized  in accordance with FIN 28, "Accounting for Stock
Appreciation  Rights  and  Other Variable Stock Option or Award Plans," over the
vesting  periods  of  the  related  options,  generally four years.  The Company
recognized  stock  compensation  expense  of  $2.5  million, $7.4 million, $14.0
million  for  the  years  ended  December 31, 2002, 2001 and 2000, respectively.

Stock  Purchase  Plan.  In  January  2000, the Company adopted the 2000 Employee
Stock  Purchase  Plan (the "ESPP").  The ESPP allows for qualified employees (as
defined in the ESPP) to purchase shares of the Company's common stock at a price
equal  to the lower of 85% of the closing price at the beginning of the offering
period  or  85%  of  the  closing price at the end of each purchase period.  The
Company  issued 388,770 shares, 224,780 shares and 88,683 shares of common stock
during  2002,  2001  and  2000, respectively, pursuant to the ESPP at an average
price per share of $5.97, $10.56 and $11.05, respectively.  The weighted average
per share fair value for shares purchased pursuant to the ESPP during 2002, 2001
and 2000 was $4.45, $6.60 and $5.08, respectively.  A total of 300,000 shares of
common stock were initially authorized for issuance under the ESPP.  On the last
day  of  each  year  for  ten  years,  starting  in 2000, the share reserve will
automatically  be increased by a number of shares equal to the greater of: 0.75%
of  the Company's outstanding shares on a fully-diluted basis; or that number of
shares  subject to stock awards granted under the plan during the prior 12-month
period.

401(k) Plan

The  Company  sponsors  a  401(k) Retirement Plan whereby eligible employees may
elect  to contribute up to the lesser of 20% of their annual compensation or the
statutorily  prescribed  annual  limit  allowable under Internal Revenue Service
regulations.  The 401(k) Plan permits the Company to make matching contributions
on  behalf  of  all participants.  Beginning in 2002, the Company matched 50% of
the  first  4%  of participant contributions into the 401(k) Plan in the form of
Company stock.  The Company expensed approximately $521,000 related to the stock
match  for  the  year  ended  December  31,  2002.

NOTE 11 INCOME TAXES

The  Company  has incurred net losses since inception and, consequently, has not
recorded any U.S. federal or state income taxes.  The Company has recorded a tax
provision of approximately $345,000 for the year ended December 31, 2002 related
to  income  earned  in  its  foreign  operations.

At  December 31, 2002, the Company had federal and California net operating loss
carryforwards  of  approximately  $76.6 million and $36.7 million, respectively,
which  expire at various dates beginning in the year 2003.  The Company also had
federal  and  California  research  and  development  credit  carryforwards  of
approximately  $10.8 million in each jurisdiction, which expire at various dates
beginning  in  the  year  2010.

Under  the  Internal  Revenue Code, certain substantial changes in the Company's
ownership  could  result  in an annual limitation on the amount of net operating
loss carryforwards that can be utilized in future years to offset future taxable
income.  The  annual  limitation  may  result in the expiration of net operating
losses  and  credits  before  utilization.

Deferred tax assets and liabilities reflect the net tax effects of net operating
loss  and credit carryforwards and of temporary differences between the carrying
amounts  of  assets and liabilities for financial reporting and the amounts used
for  income  tax  purposes.

The  Company's  deferred tax assets and liabilities consist of the following (in
thousands):

Realization  of  deferred  tax assets is dependent upon future earnings, if any,
the timing and amount of which are uncertain.  Accordingly, the net deferred tax
assets have been fully offset by a valuation allowance.  The valuation allowance
increased by $69.1 million, $8.9 million and $27.8 million during 2002, 2001 and
2000,  respectively.

2001  and  2000,  respectively.

In  September  2000,  the  Company  entered  into  a master lease agreement (the
"Master  Lease") with a third-party lessor for a secured equipment lease line of
up  to  $13.1  million.  The  Master Lease provided for quarterly borrowings and
expired  in  June  2001. Each quarterly borrowing has a 3.5 year repayment term.
At  December  31,  2002,  $5.5  million  was outstanding under the Master Lease.
Under  the  Master Lease, the Company is subject to certain financial covenants.
As  of  December  31,  2002, the Company was in compliance with these covenants.
During  2000,  the  Company  entered  into an equipment sale-leaseback agreement
under  the  Master  Lease  resulting in proceeds to the Company of approximately
$9.8  million.

During  April  2001,  the  Company  entered into a master lease agreement with a
third-party  lessor  for a secured equipment lease line of credit of up to $12.0
million,  which  expired on March 31, 2002.  The master lease agreement provides
for  a periodic delivery structure. Each delivery has a payment term of 36 or 48
months  depending  on  the  type  of the equipment purchased under the lease. At
December  31,  2002, $7.4 million was outstanding under the equipment lease line
of  credit.  Under the master lease agreement, the Company is subject to certain
financial covenants. As of December 31, 2002, the Company was in compliance with
all  such  covenants.

Licensing Agreements

The  Company  has  entered  into  several  licensing  agreements  with  various
universities  and  institutions  under  which  it  obtained  exclusive rights to
certain  patent,  patent  applications  and  other technology.  Aggregate future
payments  pursuant  to  these  agreements  are  as  follows  (in  thousands):

                                          =========


In  addition  to  the payments summarized above, the Company is required to make
royalty  payments  based  upon  a  percentage  of  net  sales of any products or
services  developed  from  certain  of  the  licensed technologies and milestone
payments  upon  the  occurrence  of  certain  events  as  defined by the related
agreements.  No such royalties or milestones have been paid through December 31,
2002.

Minimum Purchase Obligation

During  November  2002,  the  Company  entered  into  a manufacturing and supply
agreement with BMS.  BMS will manufacture bulk supply of the rebeccamycin analog
for  Exelixis.  The Company placed an initial order totaling $1.2 million.  This
initial  order  may  not  be  cancelled  and the Company is obligated to pay the
purchase  price  for that order.  The parties agreed that the purchase price for
the  initial  order would be paid in two equal installments on April 1, 2003 and
July  1,  2003.

Indemnification Agreements

The  Company  has  certain  collaboration  licensing  agreements,  which contain
standard indemnification clauses.  Such clauses typically indemnify the customer
or  vendor  for  an  adverse judgment in a lawsuit in the event of the Company's
misuse  or  negligence.  The  Company  considers  the  likelihood  of an adverse
judgment  related to an indemnification agreement to be remote.  Furthermore, in
the  event of an adverse judgment, any losses under such an adverse judgment may
be  substantially  offset  by  corporate  insurance.

ITEM  9.  CHANGES  IN  AND  DISAGREEMENTS  WITH  ACCOUNTANTS  ON  ACCOUNTING AND
FINANCIAL  DISCLOSURE

On  December 14, 2001, the Company filed a Current Report on Form 8-K announcing
the  dismissal  of  PricewaterhouseCoopers  LLP  ("PwC")  as  the  independent
accountants  of  the  Company  and  the  appointment of Ernst & Young LLP as its
independent  auditors.  The  decision  to  change  independent  accountants  was
approved  by  the  Audit  Committee  under  authority  granted  by  the Board of
Directors  of  the  Company.

The  independent  accountants'  report on the Company's financial statements for
the  fiscal  year  ended December 31, 2000 did not contain an adverse opinion or
disclaimer  of  opinion,  nor  was  the  report  qualified  or  modified  as  to
uncertainty,  audit  scope  or  accounting  principles.

In  connection  with  its  audit for the fiscal year ended December 31, 2000 and
through  December  14,  2001, there were no disagreements as defined by Item 304
(a)(1)(iv)  of  Regulation  S-K  between  the  Company  and PwC on any matter of
accounting  principles  or practices, financial statement disclosure or auditing
scope  or procedure, which disagreements, if not resolved to the satisfaction of
PwC,  would  have  caused  PwC to make reference thereto in their reports on the
financial  statements  for  such  years.

During  the  fiscal year ended December 31, 2000, and through December 14, 2001,
there were no reportable events as that term is defined in Item 304 (a)(1)(v) of
Regulation  S-K.


                                    PART III

ITEM  10.  DIRECTORS  AND  EXECUTIVE  OFFICERS  OF  THE  REGISTRANT

Information required by this item will be contained under the captions "Election
of Class I Directors," "Section 16(a) Beneficial Ownership Reporting Compliance"
and  "Executive  Compensation"  in  Exelixis'  definitive  proxy  statement with
respect to our 2003 Annual Meeting of Stockholders to be filed with the SEC (the
"Proxy  Statement"),  and  is  hereby  incorporated  by  reference  thereto.

ITEM  11.  EXECUTIVE  COMPENSATION

Information required by this item will be contained in the Proxy Statement under
the  caption  "Executive  Compensation," and is hereby incorporated by reference
thereto.

ITEM  12.  SECURITY  OWNERSHIP  OF  CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND
RELATED  STOCKHOLDER  MATTERS

Information required by this item will be contained in the Proxy Statement under
the  captions  "Security  Ownership of Certain Beneficial Owners and Management"
and "Securities Authorized for Issuance Under Equity Compensation Plans," and is
hereby  incorporated  by  reference  thereto.

ITEM  13.  CERTAIN  RELATIONSHIPS  AND  RELATED  TRANSACTIONS

Information required by this item will be contained in the Proxy Statement under
the  caption  "Certain  Transactions,"  and  is hereby incorporated by reference
thereto.

ITEM  14.  CONTROLS  AND  PROCEDURES

     Evaluation  of  disclosure  controls  and  procedures.  Based  on  their
evaluation  as  of  a date within 90 days of the filing date of this report, our
principal  executive officer and principal financial officer have concluded that
Exelixis'  disclosure controls and procedures (as defined in Rules 13a-14(c) and
15d-14(c)  under  the Securities Exchange Act of 1934, as amended (the "Exchange
Act"))  are sufficiently effective to ensure that the information required to be
disclosed  by  Exelixis  in  the  reports that we file under the Exchange Act is
gathered,  analyzed  and  disclosed  with  adequate  timeliness,  accuracy  and
completeness.

     Changes  in  internal  controls.  There have been no significant changes in
our  internal controls or in other factors that could significantly affect these
controls  subsequent  to  the date of the evaluation referred to above, nor were
there  any significant deficiencies or material weaknesses in Exelixis' internal
controls.  Accordingly,  no  corrective  actions  were  required  or undertaken.

     Limitations  on the effectiveness of controls.  A control system, no matter
how  well  conceived  and  operated,  can provide only reasonable, not absolute,
assurance that the objectives of the control system are met. Because of inherent
limitations  in  all  control  systems,  no  evaluation  of controls can provide
absolute  assurance  that all control issues, if any, within a company have been
detected.

     a)  all  significant  deficiencies  in  the design or operation of internal
     controls  which  could adversely affect the registrant's ability to record,
     process,  summarize  and  report financial data and have identified for the
     registrant's  auditors  any  material  weaknesses in internal controls; and

     b)  any  fraud,  whether or not material, that involves management or other
     employees  who  have  a  significant  role  in  the  registrant's  internal
     controls;  and

6.  The  registrant's  other  certifying  officers  and I have indicated in this
annual  report whether there were significant changes in internal controls or in
other  factors  that  could significantly affect internal controls subsequent to
the  date  of  our most recent evaluation, including any corrective actions with
regard  to  significant  deficiencies  and  material  weaknesses.
