                        EXELIXIS ANNOUNCES SECOND QUARTER
                             2003 FINANCIAL RESULTS

SOUTH SAN FRANCISCO, Calif. - August 6, 2003 - Exelixis, Inc. (Nasdaq: EXEL)
today reported financial results for the quarter ended June 30, 2003.

For the quarter ended June 30, 2003, the company reported a net loss of
approximately $23.4 million, or $0.39 per share, under generally accepted
accounting principles (GAAP), compared to a net loss of $23.9 million, or $0.43
per share, for the quarter ended June 30, 2002. Excluding discontinued
operations, non-cash charges for stock compensation, amortization of intangibles
and gain on insurance settlement, the company reported a non-GAAP net loss of
approximately $23.9 million, or $0.40 per share for the quarter ended June 30,
2003. For the quarter ended June 30, 2002, the comparable non-GAAP net loss was
approximately $22.1 million, or $0.39 per share. A reconciliation of GAAP net
loss to non-GAAP net loss is set forth at the end of this press release.

At June 30, 2003, cash, cash equivalents, short-term investments and restricted
cash totaled approximately $237.9 million compared to $222.0 million at December
31, 2002. The cash balance as of June 30, 2003 includes $66.4 million of net
proceeds from the Company's follow-on public offering completed June 25, 2003.

For the quarter ended June 30, 2003, total revenues were approximately $13.0
million, compared to $9.9 million for the same period of 2002. The increase from
2002 to 2003 was driven primarily by revenue from our October 2002
corporate  collaboration  with  SmithKlineBeecham Corporation (GlaxoSmithKline).

Research and development expenses for the quarter ended June 30, 2003 were $32.5
million, including stock compensation expense of $0.2 million, compared to $29.3
million, including stock compensation $0.5 million, for the equivalent period of
2002. The increase in the quarter from the 2002 levels was driven primarily by
an increase in personnel costs and activities related to advancing our clinical
and preclinical development programs. These activities included: initiating the
Phase 1 safety trial for XL784; advancing a new series of development
candidates, including XL647 and XL999, into preclinical testing in anticipation
of filing additional IND applications; manufacturing those compounds to support
preclinical studies; and expanding our development capabilities to support an
expanding clinical pipeline.

General and administrative expenses for the quarter ended June 30, 2003 were
$4.7 million, including a net reversal of previously recorded stock compensation
expense of approximately $27,000 due to employee terminations, compared to $4.9
million, including stock compensation of $0.3 million, for the equivalent period
of 2002.

"We delivered a strong company performance in the second quarter by meeting our
revenue expectations and managing our expenses while continuing to advance our
clinical programs. Overall this quarter, we believe that we made solid progress
toward meeting our clinical, strategic and financial objectives for the year,
and realizing our long-term goal of building a sustainable pharmaceutical
business," said George A. Scangos, Ph.D., president and chief executive officer.

Continued Dr. Scangos: "In terms of clinical progress, we initiated the Phase 1
safety trial for XL784 on schedule, and advanced our discussions with the FDA
concerning design of the Phase 3 trial for XL119. We anticipate finalizing the
development plan for XL119 in the fall, following which we will undertake
activities leading toward initiation of the registration trial. We also advanced
two promising anticancer compounds, XL647 and XL999, into preclinical
development and, assuming acceptable toxicology results, anticipate filing INDs
for these compounds."

Added Dr. Scangos: "A highlight of the quarter was our follow-on public offering
resulting in a strengthening of our balance sheet with an additional $75
million, including proceeds from our underwriters' exercise of the
over-allotment in July 2003. With these additional resources, we plan to
continue to advance key preclinical programs, expand our pipeline of clinical
compounds, advance our proprietary programs and, at the same time, meet
obligations to our corporate partners. We are appreciative of the additional
support we received in the offering from existing and new investors. We are
committed to managing our financial performance as conscientiously as we execute
on our clinical and strategic goals. We will continue to carefully review our
expenses with the goal of focusing investment in programs that directly advance
our business goals. We believe that cost-containment is an ongoing
responsibility and we intend to operate with equal emphasis on productivity,
high quality performance and fiscal responsibility."

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, other business combinations or organizational changes
that may be transacted after June 30, 2003.

With respect to financial expectations for the third quarter of 2003 compared to
the second quarter, we expect our revenues to remain relatively flat, largely
due to an increase in compound deliveries under our combinatorial chemistry
collaborations offset by the impact of the conclusion of our collaboration with
Protein Design Labs, Inc. in May 2003. We expect our operating expenses,
excluding non-cash charges, to increase by 5% or less as we expand efforts on
preclinical and clinical programs, offset by aggressive cost control measures.
With continued emphasis on cost containment we are confident that we can meet
our expense guidance for the year. With respect to cash burn for the year, we
believe that our goals to establish one or two new collaborations in 2003 are
achievable and, combined with our cost-containment initiatives, should enable us
to meet our cash burn guidance for the year. The timing for completing any
potential collaborations, and the recording of revenue ratably from them, will,
however, have an impact on our ability to meet our revenue targets for the year.
