6. Loss per Share

In the three and nine months ended September 30, 2011 and 2010, 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 or investor warrants, since their inclusion would be antidilutive.

For the three and nine months ended September 30, 2011, 46,102,000 shares attributable to outstanding warrants and stock options, and for the three and nine months ended September 30, 2010, 5,752,000 shares attributable to outstanding stock options were excluded from the calculation of diluted earnings per share because the effect would have been antidilutive.
