| (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. | |
