(1) 6, 56 and 231 shares of restricted stock and restricted stock units were not included in the computation of net income per diluted share at December 31, 2011, 2010 and 2009, respectively, because the effect would be antidilutive.

(2) Options to purchase 4,606 shares, 5,995 shares and 6,032 shares outstanding at December 31, 2011, 2010, and 2009, respectively, were not included in the computation of net income per diluted share because the exercise price of these options was greater than the average maket price of the common shares and, therefore, the effect would be antidilutive.
