                    EXELIXIS RESTRUCTURES TO FOCUS RESOURCES
                         ON EXPANDING CLINICAL PIPELINE

SOUTH SAN FRANCISCO, Calif. - June 30, 2004 - Exelixis, Inc. (Nasdaq: EXEL) has
implemented a restructuring and consolidation of its research and discovery
organizations designed to optimize its ability to generate multiple new,
high-quality investigational new drug applications (IND) per year and rapidly
advance these new drug candidates through clinical development. The company
anticipates realizing significant cost-savings and efficiencies through the
restructuring that will enhance the quality and growth of the company's maturing
franchise of proprietary anticancer compounds while at the same time ensure its
ability to fulfill obligations to corporate partners.

Most of the headcount reductions will be in the company's research organization.
The restructuring will result in a reduction in force of 62 positions or
approximately 11% of the company's personnel and is expected to result in cost
savings of at least $5 million in 2004 (excluding the restructuring charge) and
annual cost savings of at least $10 million in 2005 and beyond. The company
anticipates recording a restructuring charge of approximately $2 million during
the second quarter of 2004, comprised primarily of involuntary termination
benefits. The company will formally update its year 2004 expense and cash
guidance in connection with its second quarter 2004 financial results press
release.

"Exelixis has successfully evolved from a research-focused to a product-focused
company with a growing pipeline of what we believe are exciting anticancer
compounds that have significant therapeutic and commercial potential," said
George A. Scangos, Ph.D., president and chief executive officer. "Our early
investment in model systems genetics and comparative genomics has succeeded in
generating a rich portfolio of targets and biological insights sufficient to
fuel our discovery and development activities for the foreseeable future. We
believe that consolidating research and discovery into a single, integrated
organization will enable us to increase the quality, quantity and speed of our
proprietary programs. In this restructuring, we have been careful to provide
sufficient resources to fulfill our commitments to our current and potential new
corporate partners."

Continued Dr. Scangos: "As a result of this restructuring, many talented
employees will be leaving the company. We are deeply appreciative of their
contributions to Exelixis' progress, and are committed to support their career
transition activities."

A key aspect of the restructuring is the consolidation of the research and
discovery groups into a single, integrated and streamlined organization. This
organization will be led by Michael M. Morrissey, Ph.D., senior vice president,
discovery, reporting to Dr. Scangos. Gregory D. Plowman, M.D., Ph.D., former
senior vice president, research, will assume the role of chief science officer,
reporting to Dr. Scangos. The development organization, which is anticipated to
continue to increase in size, will remain under the leadership of Jeffrey R.
Latts, M.D., senior vice president and chief medical officer, reporting to Dr.
Scangos.

Exelixis, Inc. (Nasdaq: EXEL) is a leading genomics-based drug discovery company
dedicated to the discovery and development of novel therapeutics. The company is
leveraging its fully integrated gene-to-drug platform to fuel the growth of its
proprietary drug pipeline. Exelixis' development pipeline includes: XL119
(becatecarin), for which a Phase 3 clinical trial has been initiated in patients
with bile duct tumors; XL784, which has completed a Phase 1 clinical trial;
XL647, which is currently in a Phase 1 clinical trial; XL999 for which an IND
application has been filed; XL844, XL820 and XL880, anticancer compounds that
are potential IND candidates; and multiple compounds in preclinical development.
Exelixis has established broad corporate alliances with major pharmaceutical and
biotechnology companies, including GlaxoSmithKline (GSK) and Bristol-Myers
Squibb Company. Pursuant to a product development and commercialization
agreement between Exelixis and GSK, GSK has the option, after completion of
Phase 2a clinical trials, to elect to develop a certain number of the cancer
compounds in Exelixis' product pipeline, which may include the cancer compounds
identified in this press release (other than the company's cancer compound
XL119), thus potentially triggering milestone payments and royalties from GSK
and co-promotion rights by Exelixis. The company has also established
agricultural research collaborations with Bayer CropScience, Dow AgroSciences
and Renessen LLC. Other partners include Merck & Co., Inc., Schering-Plough
Research Institute, Inc., Cytokinetics, Inc., Elan Pharmaceuticals, Inc. and
Scios Inc. For more information, please visit the company's web site at
