(4) NET LOSS PER SHARE


Basic and diluted net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding for the applicable period. 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, warrants and convertible notes for the nine months ended September 30, 2013 and 2012 (in thousands):
