For the three months ended September 30, 2014, stock options and warrants with respect to an aggregate of 1,482 shares have been excluded from the computation of the number of shares used in the diluted earnings per share because the exercise price of the options and warrants was greater than the average market price of the underlying common stock and the effect of their inclusion would have been anti-dilutive.

For the three months ended September 30, 2013, stock options, unvested shares of restricted stock, restricted stock units and warrants with respect to an aggregate of 2,556 shares have been excluded from the computation of the number of shares used in the diluted earnings per share.  For the nine months ended September 30, 2014 and 2013, stock options, unvested shares of restricted stock, restricted stock units and warrants with respect to an aggregate of 3,248 and 2,467 shares have been excluded from the computation of the number of shares used in the diluted earnings per share, respectively.  These shares have been excluded because we incurred a net loss for each of these periods and their inclusion would be anti-dilutive.
