Net Loss Per Common Share

Basic loss per common share is calculated by dividing net loss by the weighted average number of common shares outstanding during the period.

Approximately 10,420,000 and 10,460,000 shares of common stock issuable upon the exercise of our outstanding stock options or warrants were excluded from the calculation of net loss per share for the nine-month and three-month periods ended August 31, 2011 and 2010, respectively, because the effect would be anti-dilutive.
