Note  1.   Organization  and  Summary  of  Significant  Accounting  Policies

Organization
- ------------

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  Presentation
- -----------------------

The accompanying unaudited consolidated condensed financial statements have been
prepared  by  the  Company  in  accordance  with accounting principles generally
accepted  in  the United States of America for interim financial information and
pursuant  to  the  instructions to Form 10-Q and Article 10 of Regulation S-X of
the Securities and Exchange Commission ("SEC"). Accordingly, they do not include
all  of  the information and footnotes required by generally accepted accounting
principles  for  complete  financial statements. In the opinion of the Company's
management,  all  adjustments  (consisting  of  normal  recurring  adjustments)
considered  necessary  for  a  fair  presentation  have been included. Operating
results  for  the  three-month  period  ended March 31, 2002 are not necessarily
indicative  of the results that may be expected for the year ending December 31,
2002,  or  for any future period. These financial statements and notes should be
read in conjunction with the consolidated financial statements and notes thereto
for  the year ended December 31, 2001 included in the Company's Annual Report on
Form  10-K.

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 if
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.

Comprehensive  Income  (Loss)
- -----------------------------

Comprehensive  income  (loss)  generally represents all changes in stockholder's
equity except those resulting from investments or contributions by stockholders.
Total  comprehensive  loss  amounted  to $19.7 million and $12.5 million for the
three-month  periods  ended  March  31,  2002  and  2001,  respectively.

Recent  Accounting  Pronouncements
- ----------------------------------

On  January  1,  2002,  the  Company  adopted  Statement of Financial Accounting
Standards ("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
acquired  assembled  workforce as goodwill because it is no longer defined as an
acquired  intangible  asset  under  SFAS  No.  141,  "Business  Combinations".
Accordingly,  no  acquired  workforce  amortization  was  recognized  during the
quarter  ended  March  31,  2002.  The  provisions  of SFAS 142 also require the
completion of a transitional impairment test within six months of adoption, with
any  impairments  treated  as  a  cumulative  effect  of  change  in  accounting
principle.  During  the  quarter ended March 31, 2002, the Company completed the
transitional  impairment  test,  which  did not result in impairment of recorded
goodwill.  The  Company  will continue to monitor the carrying value of goodwill
through  the  annual  impairment  tests.  For  further  discussion,  see Note 4,
"Goodwill  and  Other  Acquired  Intangibles".

A  reconciliation  of previously reported net loss and net loss per share to the
amounts  adjusted  for  the  exclusion  of  goodwill  and  assembled  workforce
amortization  follows  (in  thousands,  except  per  share  amounts):

On  January  1,  2002,  the  Company  adopted  SFAS No. 144, "Accounting for the
Impairment  or Disposal of Long-Lived Assets" ("SFAS 144").  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  the  Company's  financial  position  or  results  of  operations.

Note  2.  Genomica  Exit  Plan

During December 2001, in connection with the acquisition of Genomica Corporation
("Genomica"),  Exelixis  adopted  an  exit  plan  for  Genomica  to  improve the
operating efficiency of the combined company.  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.

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

Note  3.  Derivative  Financial  Instruments

Beginning  in  2002,  the  Company  manages  exposures to the changes in foreign
currency  exchange  rates through a program of risk management 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  other  accrued  liabilities.

The  Company  has  entered  into  foreign  currency  exchange combination option
contracts  denominated  in European Union euro to minimize the effect of foreign
exchange  rate  movements on the cash flows related to the Company's payments to
its  German  subsidiaries for services provided by the subsidiaries. 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  the  period  of  change.

During  the three months ended March 31, 2002, the Company recognized no gain or
loss related to the ineffective portion of the hedging instruments.  As of March
31,  2002,  the Company expects to reclassify $18,000 of net gains on derivative
instruments  from  accumulated  other  comprehensive income to earnings over the
next  12  months  due  to  the  payment  of  foreign  currency  to  its  German
subsidiaries.

Note  4.  Goodwill  and  Other  Acquired  Intangibles

In connection with the Company's May 2001 acquisition of Artemis Pharmaceuticals
GmbH  ("Artemis"), Exelixis received a call option from, and issued a put option
to,  certain  stockholders  of Artemis for the issuance of approximately 480,000
shares  of  Exelixis  common  stock  in  exchange  for  the remaining 22% of the
outstanding  capital  stock  of  Artemis held by the option holders.  In January
2002,  Exelixis  exercised  its  call  option  for the purchase of the remaining
329,591  shares.  The  additional  purchase price was recorded as an increase to
goodwill  of  approximately  $4.0  million.

The  Company performed an impairment test of goodwill as of January 1, 2002.  No
impairment  charge  was  necessary.

The  components of the Company's other acquisition-related intangible assets are

Note  5.  Subsequent  Event

In  April  2002,  Exelixis sold the Genomica software business to Visualize Inc.
("Visualize")  for  future  consideration of up to $2.35 million in license fees
and  future  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.  In addition, Visualize
assumed the lease obligation for the Company's abandoned facility in Sacramento,
California.  Exelixis retained an internal use license for the software.  In the
second  quarter  of  2002, the Company anticipates recording this transaction as
discontinued  operations of the Genomica business.  Management is in the process
of  evaluating  the  financial  impact  of  this  transaction.

Item  2.   Management's  Discussion  and  Analysis  of  Financial  Condition and
           Results  of  Operations

This  discussion  and  analysis should be read in conjunction with our financial
statements  and  accompanying notes included in this report and the 2001 audited
financial  statements  and  notes  thereto included in our Annual Report on Form
10-K for the year ended December 31, 2001. Operating results are not necessarily
indicative  of  results  that  may  occur  in  future  periods.

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  achievement  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 those discussed in the forward-looking statements as a result
of  various  factors,  including  but  not limited to, those discussed under the
caption "Item 5 - Risk Factors" and those discussed elsewhere in this report and
in  our Annual Report on Form 10-K.  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 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:  Aventis  CropScience  LLC,  Bayer
Corporation,  Bristol-Myers  Squibb  Company (two collaborations), Cytokinetics,
Inc.,  Dow  AgroSciences  LLC,  Elan  Pharmaceuticals,  Inc., Merck & Co., Inc.,
Protein  Design  Labs,  Inc., Scios Inc. and Schering-Plough Research Institute,
Inc.

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.
and  Accelrys,  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.

Results  of  Operations

     Revenues

Total  revenues  were  approximately  $11.6  million  and  $7.7  million for the
three-month  periods  ended March 31, 2002 and 2001, respectively.  The increase
in  revenues over the 2001 level was primarily driven by revenues from corporate
collaborations  established  in  2001 with Protein Design Labs and Bristol-Myers
Squibb  and  compound  deliveries under one of our four chemistry collaborations
established  in 2001 to jointly design custom high-throughput screening compound
libraries.

     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 $26.4 million and $16.8 million for the three-month periods ended
March  31, 2002 and 2001, respectively.  The increase in 2002 over 2001 resulted
primarily  from  the  following  costs:

- -    Increased  Personnel  -  Staffing  costs  for the three-month period ended
     March  31,  2002  increased  by  approximately  61%  to approximately $10.9
     million  from the three-month period ended March 31, 2001. The increase was
     to  support  new  collaborative  arrangements  and  Exelixis'  internal
     proprietary research efforts, including increased expenses related to staff
     hired with the acquisition of Artemis in May 2001. 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 and the
     significant  expansion  of  drug  discovery  operations,  the  cost  of lab
     supplies  increased  105% to approximately $5.1 million for the three-month
     period  ended  March  31,  2002  from  the  period  ended  March  31, 2001.

- -    Increased  Licenses  and  Consulting  -  To  support  new  collaborative
     arrangements,  conduct pre-clinical and clinical development, manufacturing
     and  further  development  of  proprietary programs, license and consulting
     expenses  increased  81%  to approximately $2.0 million for the three-month
     period  ended  March  31,  2002 from the three-month period ended March 31,
     2001.

As  part  of  our  new  collaboration with Bristol-Myers Squibb in July 2001, we
received  an exclusive worldwide license to develop and commercialize a selected
analogue  of  the  Bristol-Myers  Squibb anticancer compound, DEAE Rebeccamycin.
Phase I trials of the Rebeccamycin analogue have been completed and demonstrated
an acceptable safety profile. In ongoing Phase II trials, being conducted by the
National  Cancer  Institute, the compound has demonstrated activity against some
tumor types.  Planning for additional clinical studies is currently underway and
should  be  finalized later in 2002.  During the period ended March 31, 2002, we
continued  to grow our clinical research and development staff.  We currently do
not have manufacturing capabilities or experience necessary to produce materials
for  clinical  trials.  We  plan  to  rely  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 new product
candidates and additional trials for our Rebeccamycin analogue.  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.

We  expect  to  continue  to  devote  substantial  resources  to  research  and
development,  and 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.

     General  and  Administrative  Expenses

General  and  administrative  expenses  consist  primarily of personnel costs to
support  our  research  and  development  activities,  facilities  costs  and
professional  expenses,  such as legal fees. General and administrative expenses
were  approximately  $4.9  million  and $4.3 million for the three-month periods
ended  March 31, 2002 and 2001, respectively.  The increase in 2002 over 2001 of
approximately  14%,  was driven primarily by costs associated with personnel and
facilities  to  support  expansion  in  our research and development operations.

     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  March  31,  2002,  we  have approximately $3.2 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 additional deferred stock compensation during the
three-month  period  ended  March  31, 2002, compared to $0.2 million during the
three-month  period  ended  March  31,  2001.  These  amounts were recorded as a
component  of stockholders' equity and are being amortized as stock compensation
expense  over the vesting periods of the options, which is generally four years.
We  recognized  stock  compensation expense of $0.8 million and $1.9 million for
the  three-month  periods  ended  March  31,  2002  and 2001, respectively.  The
decrease  in  stock  compensation  expense  in  2002  compared to 2001 primarily
resulted  from the accelerated amortization method used for accounting purposes.

During  April  2001, we granted approximately 545,000 supplemental stock options
under  our  2000  Equity Incentive Plan to certain employees (excluding officers
and  directors)  who had stock options under the 2000 Equity Incentive Plan with
exercise  prices  greater  than  $16.00  per  share.  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  FASB Interpretation Number 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 period ended March 31,
2002,  we  recorded  a  reversal  of  previously  recorded  compensation expense
relating  to  the  supplemental options of $246,000 resulting from a decrease in
the  market  value  of  our  common  stock.

     Amortization  of  Goodwill  and  Intangibles

We  implemented  Statement  of  Financial Accounting Standards ("SFAS") No. 142,
"Goodwill  and  Other  Intangible  Assets"  ("SFAS  142"),  on  January 1, 2002.
Accordingly,  goodwill  and  other  intangible  assets deemed to have indefinite
lives  are  no  longer  being amortized but will be subject to annual impairment
tests  in  accordance  with  SFAS  142.

Goodwill  and  intangibles result from our acquisitions of Genomica, Artemis and
Agritope (now renamed Exelixis Plant Sciences).  Amortization of intangibles was
$0.2  million  for the three-month period ended March 31, 2002, and amortization
of  goodwill  and  intangibles was $1.1 million for the three-month period ended
March 31, 2001.  The decrease from 2001 was primarily related to our adoption of
SFAS  142.

     Other  Income  (Expense)

Other  income  (expense)  primarily  consists of interest income earned on cash,
cash  equivalents  and  short-term  investments,  partially  offset  by interest
expense  incurred  on  notes  payable and capital lease obligations. Total other
income  (expense)  was  income  of $1.5 million for the three-month period ended
March  31, 2002, compared to income of $1.7 million for the comparable period in
2001.  The  decrease year-over-year primarily relates to an increase in interest
expense  on  capital  lease  obligations  and notes payable, partially offset by
increased interest income as a result of increased cash and investment balances.

Liquidity  and  Capital  Resources

Since  inception, we have financed our operations primarily through issuances of
capital  stock,  loans, equipment lease financings and other loan facilities and
payments  from  collaborators.  In  addition,  during December 2001, we acquired
Genomica,  including  $109.6  million  in cash and investments.  As of March 31,
2002,  we  had  approximately  $198.1  million  in  cash,  cash  equivalents and
short-term  investments.

Our  operating  activities  used  cash  of  approximately $26.3 million and $0.6
million for the three-month periods ended March 31, 2002 and 2001, respectively.
For  the  three-month  period  ended  March  31,  2002,  cash  used in operating
activities  related  primarily  to  funding  net operating losses, cash payments
related  to our December 2001 acquisition of Genomica and a decrease in deferred
revenue  from  collaborators,  partially  offset  by non-cash charges related to
depreciation  and  amortization  of  deferred  stock  compensation  and  other
intangible  assets.  For  the  comparable period in 2001, cash used in operating
activities  related  primarily to funding net operating losses and cash payments
related  to  our December 2000 acquisition of Agritope, almost completely offset
by  an  increase  in  deferred  revenues from collaborators and non-cash charges
related  to  depreciation  and  amortization  of  deferred  stock  compensation,
goodwill  and  other  intangible  assets.

Our  investing activities provided cash of approximately $13.8 million and $21.5
million for the three-month periods ended March 31, 2002 and 2001, respectively.
The  cash  provided  resulted  from  the  proceeds from maturities of short-term
investments,  partially  offset  by  purchases  of  short-term  investments  and
property  and  equipment.

Our  financing  activities  used  cash  of  approximately  $1.6 million and $1.2
million for the three-month periods ended March 31, 2002 and 2001, respectively.
The  cash  used  resulted  primarily  from  principal  payments on capital lease
obligations  and  notes  payable,  partially  offset  by repayment of notes from
stockholders  and  proceeds from the exercise of stock options and warrants, net
of  repurchases.

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  Form 10-Q 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  its  business  and  operating  results.

Recent  Accounting  Pronouncements

On  January  1,  2002,  we  adopted  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
and  other  intangible  assets  deemed  to  have  indefinite  lives no longer be
amortized,  and  instead,  be  tested  for  impairment  on  a  periodic  basis.

In  accordance  with  SFAS  142,  we  discontinued  the amortization of goodwill
effective  January  1, 2002. In addition, we re-characterized acquired assembled
workforce  as goodwill because it is no longer defined as an acquired intangible
asset  under  SFAS  No.  141,  "Business Combinations". Accordingly, no acquired
workforce  amortization  was recognized during the quarter ended March 31, 2002.
The  provisions  of  SFAS  142  also  require  the  completion of a transitional
impairment test within six months of adoption, with any impairments treated as a
cumulative  effect  of  change in accounting principle. During the quarter ended
March  31,  2002,  we  completed the transitional impairment test, which did not
result  in  impairment  of  recorded  goodwill.  We will continue to monitor the
carrying  value  of  goodwill  through  the  annual  impairment  tests.

We  adopted  SFAS  No.  144,  "Accounting  for  the  Impairment  or  Disposal of
Long-Lived  Assets"  on  January 1, 2002 ("SFAS 144").  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.

Item  3.  Quantitative  and  Qualitative  Disclosures  About  Market  Risk

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. As of March
31,  2002, there has been no material change in Exelixis' interest rate exposure
from  that  described  in  our  Annual  Report  on  Form 10-K for the year ended
December  31,  2001.

All  highly liquid investments with an original maturity of three months or less
from  the  date of purchase are considered cash equivalents.  Exelixis views its
available-for-sale  portfolio  as  available  for  use  in  current  operations.
Accordingly,  we  have classified all investments with an original maturity date
greater  than  three  months as short-term, even though the stated maturity date
may  be  one  year  or  more  beyond  the  current  balance  sheet  date.

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  Eurodollars.  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  March  31, 2002, we had outstanding an aggregate of
$1.9  million  (notional amount) of short-term foreign currency option contracts
denominated  in European Union euro.  The fair value of these contracts at March
31,  2002  was approximately $18,000, which is reflected on the balance sheet as
an  asset. Due to the nature of the option contracts' structure, our exposure to
adverse  changes  in  market  rates  on  these  instruments  is limited to their
carrying value. We cannot give any assurance that our hedging strategies will be
effective  or that transaction losses can be minimized or forecasted accurately.

                           PART II. OTHER INFORMATION

Item  2.   Changes  in  Securities  and  Use  of  Proceeds

(d) 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 March 31, 2002, proceeds from the offering have
been used for research and development activities, capital expenditures, working
capital,  merger  and acquisition expenses and other general corporate purposes.
In  the future, we intend to use the remaining net proceeds in a similar manner.
As  of March 31, 2002, $44.7 million of the proceeds remained available and were
primarily  invested  in  short-term  marketable  securities.

Item  5.  Other  Information  -  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 $18.4 million for the three months ended March 31, 2002. As of
that  date,  we  had  an accumulated deficit of approximately $219.6 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. During 2001, we
acquired  a compound in Phase II clinical development, and we are working with a
third-party  vendor to manufacture this compound and preparing for the filing of
an  Investigational  New  Drug  Application,  or  IND.  In addition, we are also
preparing  to  file  our  first  IND  for  a proprietary compound in 2002.  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; and
- -    the  filing,  prosecution  and  enforcement  of  patent  claims.

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
administrative  and  operational  infrastructure.  As  our  operations  expand
domestically and internationally, we expect that we will need 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), Protein Design Labs, Dow AgroSciences and Aventis. 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-month  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 six months of each other.  Our mechanism of
action  collaborative  agreement  with Bristol-Myers Squibb expires in September
2002.  Our  cancer  collaborative agreement with Bristol-Myers Squibb expires in
July  2004.  Our  collaborative  agreement 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 Aventis is scheduled
to  expire in June 2004.  The Aventis arrangement is conducted through a limited
liability  company,  Agrinomics, which is owned equally by Aventis and Exelixis.
Aventis  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.  Bayer  has  an  agreement  to  acquire
Aventis,  and  we have not been advised of the status of the existing Agrinomics
agreement  following  completion  of  the  acquisition.

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,
eliminating  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.

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. Any conflict with
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,  market  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.

WE  ARE  DEPLOYING  UNPROVEN  TECHNOLOGIES,  AND  WE  MAY NOT BE ABLE TO DEVELOP
COMMERCIALLY  SUCCESSFUL  PRODUCTS.

Our  research  and  operations  thus far have allowed us to identify a number of
product  targets  for  use  by  our  collaborators  as well as targets and small
molecule  compounds  for  our  own  internal  development  programs.  We are not
certain,  however,  of  the  commercial  value  of  any of our current or future
targets  and  molecules,  and we may not be successful in expanding the scope of
our  research  into  new  fields  of  pharmaceutical  or  agricultural research.
Significant  research and development, financial resources and personnel will be
required  to  capitalize on our technology, develop commercially viable products
and  obtain  regulatory  approval  for  such  products.

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 Investigational New
Drug  Application  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  advisors  and  collaborators  at  academic and other
institutions  that  assist  us  in  our  research and development efforts. These
scientists are not our employees and may have other commitments that would limit
their  availability  to  us.  Although our scientific 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 scientific advisors and collaborators sign
agreements  not  to  disclose  our confidential information, it is possible that
valuable  proprietary  knowledge  may  become  publicly  known  through  them.

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  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 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. 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
such  targets can be commercialized. If regulatory approval is granted to any of
our  products,  this  approval  may  impose  limitations on the uses for which a
product  may  be  marketed.  Further,  once  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  TRIALS  ON  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 studies to date have been conducted by the National Cancer
Institute,  or NCI.  We will have to conduct additional studies in order to meet
FDA  requirements  for  regulatory  approval.  We  have  no  prior experience in
conducting  clinical  studies,  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 or
assure that any specified timelines with respect to the initiation or completion
of  clinical  studies  may  be  achieved.

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 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 studies.
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 studies could
delay  the filing of our INDs and the initiation of clinical trials that we have
currently  planned.

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 milestones 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 became freely tradable following the acquisition.
Similarly,  shares  of  common  stock held by existing stockholders prior to the
public offering became freely tradable in 2000, subject in some instances to the
volume  and  other  limitations  of  Rule  144.  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.
