(1) Earnings in 2002, the three months ended March 31, 2003, and the three months ended March 31, 2004 were insufficient to cover fixed charges by approximately $3.4 million, $6.8 million and $35.7 million respectively.

(2) During the three months ended March 31, 2004, as a result of the March 2004 refinancing, we recognized an ordinary loss on early extinguishment of debt of $28.8 million, which consisted of $25.9 million in premium payments to holders of the subordinated notes we prepaid and a write-off of $2.9 million of debt issuance costs associated with all the debt paid.
