Item 5.04 Temporary Suspension of Trading Under Registrant’s Employee Benefit Plans.

On April 29, 2008, Exelixis, Inc. (the “Company”) sent a notice to its directors and executive officers informing them of a change in the end date of an ongoing suspension period (the “Blackout Period”) under the Exelixis, Inc. 401(k) Plan (the “Plan”). This notice was an update to an earlier notice which was sent to directors and executive officers on March 28, 2008 and reported on a Current Report on Form 8-K filed on March 28, 2008. Directors and executive officers of the Company are prohibited from trading in the Company’s securities during the Blackout Period.

The Blackout Period is the result of the scheduled transition of investment, trustee and recordkeeping services under the Plan to a new trustee and administrator. The Blackout Period began on Monday, March 24, 2008 at 1:00 p.m. P.S.T. and was originally expected to end on or before May 21, 2008. Since the transition of services to the new trustee and administrator is nearing completion, the end date of the Blackout Period has changed. The Blackout Period is now expected to end on or before May 2, 2008.

The updated notice was provided pursuant to Section 306(a) of the Sarbanes-Oxley Act of 2002 and a copy of the updated notice is attached hereto as Exhibit 99.1 and incorporated herein by reference.

Item 9.01. Financial Statements and Exhibits.
