[1] Diluted loss per share was computed without consideration to potentially dilutive instruments as their inclusion would have been antidilutive. Potentially dilutive instruments include stock options, unvested restricted stock awards, convertible preferred stock, senior unsecured convertible notes and warrants. At April 30, 2014 and 2013, there were options to purchase 3.1 million shares of common stock.
