Our basic and diluted net loss per share is computed using the two-class method.  The two-class method is an earnings allocation that determines net income per share for each class of common stock and participating securities according to their participation rights in dividends and undistributed earnings or losses.  Non-vested restricted stock that includes non-forfeitable rights to dividends are considered participating securities. 

Because we have incurred a net loss for all periods presented, diluted net loss per common share is the same as basic net loss per common share. The following contingently issuable and convertible equity shares were excluded from the calculation of diluted net loss per share because their effect would have
been anti-dilutive for all periods presented:
