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, 2012 and 2011, and for the period of August 5, 2004 through December 31, 2012 was $263,000, $263,000 and $5,095,000, 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 lease, which became effective upon the expiration of its previous lease, for 17,000 square feet of space in the same Tempe, Arizona facility. This lease calls for monthly rental payments of $22,000, plus a proportionate share of building operating expenses and property taxes. The term of this lease is sixty months from March 1, 2008. In January of 2013, this lease was amended to extend the lease to February 28, 2015, with the rentable square feet of space reduced to 2,845 square feet and monthly rental payments of $4,000.
