NOTE 9 NET LOSS PER SHARE

Diluted net loss per share excludes the effect of outstanding potentially dilutive securities because they are anti-dilutive. The following table shows the outstanding potentially dilutive options, unvested restricted stock awards, warrants and convertible notes as of December 31, 2012, 2011 and 2010 (in thousands):
