Options not included in the computation of diluted net income per share to purchase 50,000 and 113,250 Common Shares at an average price of $15.73 and $12.89, respectively, per share were outstanding at September 30, 2011 and 2010, respectively.  These outstanding options were not included in the computation of diluted net income per share because their respective exercise prices were greater than the average market price of Company Common Shares.

There were 419,100 and 455,400 performance-based restricted Common Shares outstanding at September 30, 2011 and 2010, respectively.  These shares were not included in the computation of diluted net income per share because not all vesting conditions were achieved as of September 30, 2011 and 2010.  These shares may or may not become dilutive based on the Company’s ability to meet or exceed future earnings performance targets.
