Subsequent Events [Abstract] |
Subsequent Events | Note 19. Subsequent Events In February 2013, we sold a total of 782,755 shares of our common stock at a price per share of $2.06 for gross proceeds of approximately $1,616,000. The shares were sold under the 2012 amended sales agreement. The sales agent is paid compensation up to 3% of gross proceeds pursuant to the terms of the agreement. The shares were offered under our shelf registration statement previously filed with, and declared effective by, the SEC. In February 2013, 324,534 Series A Warrants were exercised at an exercise price of $1.40 per share. We received gross proceeds of approximately $454,000 and issued 324,534 shares of our common stock. In March 2013, we entered into a commercial lease agreement with Prologis, L.P. (Prologis), as landlord, for approximately 18,700 square feet of office and research space in Sunnyvale, California. The initial term of the lease is ten years and we will pay approximately $3.5 million as rent over the term of the lease. As part of the lease, Prologis has agreed to provide us financial allowances to build initial tenant improvements, subject to customary terms and conditions relating to landlord-funded tenant improvements. The facility will house operations that support our clinical development activities.
