Item 1.01 Entry into a Material Definitive Agreement.

On July 16, 2009, the Registrant, as tenant, entered into a First Amendment to Lease (“Amendment”) with Carr NP Properties, L.L.C. (“Landlord”). The Registrant and Landlord are party to an Office Lease dated as of April 20, 2007 (the “Existing Lease”), pursuant to which Landlord leases to Registrant its corporate headquarters, consisting of approximately 63,781 square feet of space, located at 960 Stewart Drive, Sunnyvale, California (the “Premises”). The Existing Lease was scheduled to expire on October 31, 2009.

The Amendment extends the term of the Existing Lease to September 30, 2014. The Amendment further provides for base rent as follows:

Period During Lease Term	Annual Base Rent
May 1, 2009 – September 30, 2009		N/A
October 1, 2009 – September 30, 2010	$	994,983.60
October 1, 2010 – September 30, 2011	$	1,024,833.11
October 1, 2011 – September 30, 2012	$	1,055,578.10
October 1, 2012 – September 30, 2013	$	1,087,245.44
October 1, 2013 – September 30, 2014	$	1,119,862.81

The Amendment also provides that Landlord will contribute to the cost of any interior office and lab improvements to the Premises, cabling and signage to the extent of the lesser of (i) $1,052,386.50, or (ii) the actual cost of the alterations.

The Amendment also provides Registrant with an expansion option, which gives Registrant the right (but not the obligation) to lease additional space in adjacent buildings.
