Item 1.01 Entry into a Material Definitive Agreement.

On October 23, 2008, Gilead Sciences, Inc. (the "Company") entered into a Purchase and Sale Agreement and Joint Escrow Instructions (the "Agreement") with Electronics For Imaging, Inc. ("EFI"), pursuant to which the Company agreed to acquire certain real property and improvements and certain other assets from EFI for a total purchase price of $137.5 million (the "Purchase Price").

The property to be purchased by the Company pursuant to the Agreement includes approximately 30 acres of land, which is entitled for development, the office building located at 301 Velocity Way, Foster City, California, consisting of approximately 163,000 square feet and certain other assets related to the property (collectively, the "Property"). EFI will retain ownership of the office building located at 303 Velocity Way consisting of approximately 295,000 square feet on approximately five acres of land. The Company will have a right of first offer to purchase or lease all or any portion of the office building at 303 Velocity Way and related land if EFI decides in the future to sell or lease all, or a portion, of the building.

Gilead agreed to deposit in escrow, within two business days after the date of the Agreement, $5.0 million toward the Purchase Price. On or prior to December 12, 2008, Gilead may terminate the Agreement in its sole discretion, for any reason. If Gilead elects to proceed with the purchase, Gilead will deposit in escrow an additional $5.0 million on or around December 12, 2008. After such time, the closing of the transaction will remain subject to the satisfaction of certain closing conditions, including, without limitation, the execution of certain ancillary agreements and receipt of certain consents. The Company will pay the balance of the Purchase Price on or before the closing date, which shall be a date designated by the Company after January 1, 2009 and before January 29, 2009, unless otherwise agreed by the parties.

The Company may also terminate the Agreement (i) if EFI breaches the terms of the Agreement; and (ii) if, prior to closing of the sale of the Property, there is any condemnation, damage or destruction as a result of fire or other casualty that is reasonably estimated to cost or be valued at more than $5.0 million.

The foregoing description of the Agreement does not purport to be complete and is subject to, and qualified in its entirety by reference to, the full text of the Agreement, which will be filed as an exhibit to the Company's Annual Report on Form 10-K for the period ending December 31, 2008.
