During 1998 through 2007, we were obligated under a non-cancelable operating lease agreement for a Tempe, Arizona office and research facility. Rent expense for the years ended December 31, 2011 and 2010, and for the period of August 5, 2004 through December 31, 2011 was $263,000, $263,000 and $4,832,000, respectively. We subleased portions of the Tempe facility to other tenants and approximately 45% of the Tempe facility was subleased through December 2007, which offset our lease expense. The Company recorded $2,299,000 of sublease income for the period of August 5, 2004 through December 31, 2007. The Company had no sublease income in the years subsequent to 2007.

On July 19, 2007, the Company entered into a new lease, which became effective upon the expiration of its previous lease, for 17,000 square feet of space in the same Tempe, Arizona facility. The new lease calls for monthly rental payments of $22,000, plus a proportionate share of building operating expenses and property taxes. The term of the new lease is sixty months from March 1, 2008, with an option to extend the lease for an additional twenty-four months with monthly rental payments set at $24,000, plus a proportionate share of building operating expenses and property taxes, during the extension period. Total base rent for the initial sixty-month term is approximately $1,316,000, due approximately $263,000 per year for years 2008 through 2012 and $44,000 in year 2013.
