(A)		Due to the registrant’s losses for the six months ended June 30, 2010 and for the years ended December 31, 2009, 2008, 2007, 2006, and 2005, the ratio coverage was less than 1:1. To achieve a coverage ratio of 1:1, the registrant must generate additional earnings of the amounts shown in the table below.

(B)		During the year ended December 31, 2008, the registrant repurchased $82.5 million and repaid the remaining $117.5 million of its convertible senior subordinate notes. As of December 31, 2008, the registrant therefore did not have any registered debt outstanding.
