Note 9   Commitments and Contingencies Leases   We lease space for our research and development and corporate offices in Bothell, Washington under operating leases expiring in 2016 and we lease space for research and development in Cambridge, Massachusetts under an operating lease expiring in 2012. In connection with the terms of our lease of our Bothell, Washington facility at 3830 Monte Villa Parkway, we have provided our landlord with a stand-by letter of credit. Contingencies   We are subject to various legal proceedings and claims that arise in the ordinary course of business. Our management currently believes that resolution of such legal matters will not have a material adverse impact on our consolidated financial position, results of operations or cash flows. Increase to Authorized Capital   We agreed in the Underwriting Agreement dated May 17, 2011 between our company and Roth Capital Partners, LLC, as representative of the underwriters named therein, to hold a stockholders meeting no later than August 15, 2011 in order to seek stockholder approval for an amendment to our certificate of incorporation to increase the authorized number of shares of our common stock from 90,000,000 to not less than 150,000,000 shares, and to file a certificate of amendment to our certificate of incorporation no later than two business days following such stockholder approval.
