(1)   Due to rounding, the sum of the quarterly earnings per share amounts may not equal the reported earnings per share for the year.
 
(2)   For the three months ended April 30, 2011, April 30, 2010 and January 31, 2010, there were no incremental shares attributed to outstanding options to purchase common stock because the Company reported a net loss for each period, and any incremental shares would be anti-dilutive.
