|(A) | The Company considered one-third of the rent expense as imputed interest factor.
|--- | --------------------------------------------------------------------------------

|(B) | Due to the registrants loss in 2010, 2009, and 2007, the ratio of earning to fixed charges was less than 1:1. The registrant must generate additional earnings of
$ 79.09 million, $ 96.2 million, and $ 30.4 million, respectively to achieve a coverage ratio of 1:1.
