Diluted earnings per share is computed by dividing net income by the weighted average common and potentially dilutive common equivalent shares outstanding, determined as follows:

     Incremental shares attributable to stock options and restricted stock are computed using the average market price during the related period. During the three months ended March 31, 2011, 78,767 (none at March 31, 2012) of average out-of-the-money options to purchase shares were excluded from the calculation of incremental shares attributable to stock options and restricted stock.
