6.             Loss per Share

In the three months ended March 31, 2014 and 2013, basic and diluted loss per share have been computed using only the weighted average number of common shares outstanding during the period without giving effect to any potential future issuances of common stock related to stock option programs, Rights To Shares Agreement (see Note 9), investor warrants or convertible notes, since their inclusion would be antidilutive.

For the three months ended March 31, 2014 and March 31, 2013, 248,336,287 and 166,739,613 shares, respectively, attributable to outstanding warrants, convertible notes, Rights To Shares Agreements and stock options were excluded from the calculation of diluted earnings per share because the effect would have been antidilutive.
