               EXELIXIS ANNOUNCES THIRD QUARTER FINANCIAL RESULTS

SOUTH  SAN  FRANCISCO, Calif.- November 13, 2001 - Exelixis, Inc., (Nasdaq:EXEL)
today  reported financial results for the quarter ended September 30, 2001.  For
the  quarter, the company reported a net loss of approximately $13.4 million, or
$0.28  per share, excluding non-cash charges for stock compensation expense, and
amortization  of  goodwill  and intangibles.  For the third quarter of 2000, the
net  loss was approximately $5.5 million, or $0.13 per share, excluding non-cash
charges.

At September 30, 2001, cash, cash equivalents and short-term investments totaled
approximately  $132.3  million, compared to $112.6 million at December 31, 2000.

For the quarter ended September 30, 2001, total revenues almost doubled to $11.9
million  from  $6.1  million  for the same period of 2000.  The increase was due
primarily  to  new  collaborations  formed with Bristol-Myers Squibb and Protein
Design  Labs,  in  addition  to  increased  contract  revenues  from  existing
collaborations.  The  third  quarter of 2001 also included revenues from Aventis
CropScience  resulting from the December 2000 acquisition of Agritope, Inc. (now
Exelixis  Plant  Sciences,  Inc.)  and revenues from government grants resulting
from  the  May  2001  acquisition  of  Artemis  Pharmaceuticals  GmbH.

Research  and  development  expenses  for  the  third quarter of 2001 were $21.3
million, excluding stock compensation expense of $1.1 million, compared to $11.1
million, excluding stock compensation expense of approximately $2.3 million, for
the  equivalent  period  of  2000.  The  increase  reflects  expenses  from both
Exelixis  Plant Sciences and Artemis Pharmaceuticals, neither of which were part
of Exelixis a year ago, as well as expansion of South San Francisco research and
development  to  support  new  collaborations and the continued expansion of our
drug  discovery organization.  For the quarter ended September 30, 2001, general
and  administrative  expenses totaled $4.8 million, excluding stock compensation
expense  of $0.6 million, compared to $2.6 million, excluding stock compensation
expense  of  approximately  $1.2  million,  in  the  third quarter of 2000.  The
increase  resulted  primarily  from  additional staffing required to support our
expanding worldwide research and development efforts.  The third quarter of 2001
also included $1.4 million for the amortization of goodwill and intangibles from
recent  acquisitions.

"The  third quarter was highly productive for Exelixis, both in establishing key
strategic  partnerships  with leading companies such as Bristol-Myers Squibb and
Elan  and  in moving our internal programs forward aggressively," said George A.
Scangos, Ph.D., president and chief executive officer of Exelixis, Inc.  "We are
confident  in  the robust potential of our internal pipeline and remain on track
to  announce  our  first  lead  compound  by  year  end."



Recent  Highlights:

- -    During  the  third quarter, Exelixis entered into a new collaboration with
     Bristol-Myers  Squibb to discover a new generation of cancer drugs. As part
     of  the  collaboration, BMS purchased $20 million of common stock at $33.30
     per  share.  Under the agreement, each company receives half of the targets
     generated  under the collaboration, and Exelixis also received royalty-free
     rights  to  DEAE  rebeccamycin,  a  cancer  compound  in  Phase II clinical
     development.

- -    Exelixis  signed  chemistry  collaborations  with Elan Pharmaceuticals and
     Scios,  for  the  generation  of  high-quality,  small  molecule  compound
     libraries  for  high-throughput  screening.  Exelixis  receives  financial
     compensation  for  the  compounds, which reduces the cost of developing its
     internal  libraries,  and can use these compounds for its internal programs
     in  addition  to  its  partnered  programs.

- -    As  part  of  the  initiation of a new inflammation program, scientists at
     Exelixis and the Institute of Molecular and Cellular Biology in Strasbourg,
     France,  identified  and  characterized  a  gene  involved in mediating the
     innate  immune  response,  a  discovery  that  could  have  significant
     implications  in  treating  a  wide variety of human inflammatory diseases,
     such  as  rheumatoid  arthritis,  asthma,  atherosclerosis and inflammatory
     bowel  disease.  The  findings  were published in the October 11th issue of
     Developmental  Cell.

- -    Protein Design Labs accepted several cancer antibody targets from Exelixis
     for further research and development. Under the agreement, Exelixis retains
     the  right  to  co-fund  and  co-develop  antibodies  resulting  from  the
     collaboration.  For antibody products developed by Protein Design Labs that
     Exelixis  elects  not to co-develop, Exelixis will be entitled to specified
     milestone  payments  and  royalty  payments  on  any  product  sales.

- -    Exelixis  continued  to  deliver targets and assays to partners throughout
     the  course  of  the  quarter,  earning  milestone  payments in most cases.


Outlook:

The  following  statements  are based on current expectations.  These statements
are  forward-looking  and  actual  results  may  differ  materially.  Except  as
expressly  set forth below, these statements do not include the potential impact
of  any  mergers, acquisitions or other business combinations that may be closed
or  entered  into  after  October  31,  2001.

For  the fourth quarter, Exelixis anticipates that revenues will increase in the
range of 5-10%.  Due to continued expansion of the drug discovery operations and
clinical  development  to  support  our  effort  to  file  our  first  IND for a
proprietary  lead  compound in 2002 as well as manufacture and develop our Phase
II  cancer  product,  expenses, excluding non-cash charges, will increase in the
range  of 10-15% from the third quarter levels.  For 2001, Exelixis continues to
expect  a  cash  burn  in the range of $42-47 million based on total revenues of
$40-45  million.  Exelixis  also  continues  to  expect  to  report a cash, cash
equivalents  and  short term investments balance in excess of the $112.6 million
reported  at  December  31,  2000.

Exelixis,  Inc.  is  a  leading  worldwide genomics-based drug discovery company
focused on product development through its expertise in comparative genomics and

This  press  release  contains  forward-looking  statements,  including  without
limitation the matters discussed in the "Outlook" section. These forward-looking
statements  are  based  upon  Exelixis'  current  expectations.  Forward-looking
statements  involve  risks  and  uncertainties. Exelixis' actual results and the
timing  of  events  could  differ  materially  from  those  anticipated  in  its
