Basic earnings per share has been computed using the weighted average number of common shares outstanding. Diluted earnings per share has been computed using the weighted average number of common shares and common share equivalents outstanding (which consist of warrants, options and convertible debt to the extent they are dilutive). Potentially dilutive stock options of 283,156 and 144,665 for the three months ended September 30, 2010 and 2011, respectively, were excluded from the computation of diluted earnings per share as the average market price of the Company’s common stock did not exceed the weighted average exercise price of such options and to have included them would have been anti-dilutive. Potentially dilutive stock options of 317,293 and 180,034 for the nine months ended September 30, 2010 and 2011, respectively, were excluded from the computation of diluted earnings per share as the average market price of the Company’s common stock did not exceed the weighted average exercise price of such options and to have included them would have been anti-dilutive.
