WDŽ to Relocate Headquarters to Irvine, Calif.

Western Digital Corp. (NYSE: WDC) announced today that it has finalized plans to consolidate its headquarters and other Southern Calif. operations into a single facility, relocating from its current multiple locations in Lake Forest, Calif., and Aliso Viejo, Calif., to Irvine, Calif., beginning in the fourth calendar quarter of 2010.

Since 2000, WDŽ has operated headquarters and engineering activities from a three-building campus located on Lake Forest Drive in Lake Forest. The company's significant growth over the past 10 years has required expansion into several additional nearby locations. WD's acquisition of SiliconSystems Inc. in March 2009 added a further location in Aliso Viejo. The leases for its current locations expire beginning in late 2010.

"Consolidating all our Southern California personnel under one roof will facilitate tighter team collaboration, improve operational efficiencies, rationalize facilities costs and offer flexibility for future growth," said John Coyne, president and CEO.

The company will occupy approximately 365,000 square-feet at Park Place, an existing campus located at 3355 Michelson Drive, Irvine, Calif., recently acquired by LBA Realty. The move will be completed in two phases between late calendar year 2010 and late calendar year 2011. All of the company's approximately 1,250 employees in Southern California will relocate to the new site. WD signed a 10-year lease for the site and was assisted in this transaction by the Irvine office of Studley, an international tenant representative real estate firm.

"Selection of this location is the result of a comprehensive, year-long search," said Ray Bukaty, senior vice president administration, and general counsel for WD. "It is close to where our employees live, structured to fit our unique needs for laboratories and office space, offers our employees improved amenities and is more cost effective than our current locations."
