Income (loss) before income taxes for the years ended December 31, 1999, 2002 and 2003 was not sufficient to cover fixed charges by a total of approximately $10.3 million in 1999, $15.0 million in 2002 and $132.0 million in 2003. As a result, the ratio of earnings to fixed charges has not been computed for any of these periods.
