     Options to purchase 109,032 shares, 96,801 shares and 322,933 shares of common stock for the years ended December 31, 2011, December 31, 2010 and December 31, 2009, respectively, were not included in the computation of diluted earnings per share because they were anti-dilutive, as the exercise prices of the options were greater than the average market price of the common shares. Additionally, the weighted average diluted common shares outstanding for the year ended December 31, 2009 excludes the dilutive effect of stock options and restricted stock, as inclusion of these would be anti-dilutive.  Approximately, 55,000 common share equivalents were not included in the computation of diluted earnings per share for the period ended December 31, 2009.
