Note 6. Commitments

We conduct our product research and development programs through a combination of internal and collaborative programs that include, among others, arrangements with universities, contract research organizations and clinical research sites. We have contractual arrangements with these organizations that are cancelable. Our obligations under these contracts are largely based on services performed.

We currently lease approximately 36,400 square feet of office space pursuant to non-cancelable operating leases. Our lease in Austin, TX expires in 2014. Our lease in San Mateo, CA expires in 2012. Future minimum lease payments are as follows for the years ended December 31, (in thousands):


	2012		2013		2014		Total
Future minimum lease payments	$	450	$	115	$	81	$	646

In December 2011, we entered into a sublease for our facility in San Mateo. This sublease is coterminous with our lease in San Mateo.
