The proposed amendments will eliminate substantially all of the restrictive covenants of the indentures. Adoption of the proposed amendments requires the consent of holders of at least a majority of the aggregate principal amount of each of the outstanding Notes.

Holders who validly tendered their 8.125% Notes by 5:00 p.m., New York City time, on June 20, 2005 (the "Consent Date"), and consented to the proposed amendments will receive the total consideration of $1,070.75 per $1,000.00 principal amount of Notes accepted for purchase, consisting of (i) the purchase price of $1,050.75 and (ii) the consent payment of $20.00, plus accrued interest up to, but not including, the date of acceptance. As of the Consent Date, $237,824,423, or 96.9%, in aggregate principal amount of the 8.125% Notes had been tendered in the Offer. Acceptance of and payment for such 8.125% Notes is expected to occur on June 21, 2005, subject to satisfaction or waiver of certain conditions. Upon payment for such 8.125% Notes, the amendments relating to the 8.125% Notes will become effective.

As of the Consent Date, $298,860,000, or 99.6%, in aggregate principal amount of the 9.00% Notes had been tendered in the Offer. Acceptance of and payment for such 9.00% Notes is expected to occur on June 21, 2005, subject to satisfaction or waiver of certain conditions. Upon payment for such 9.00% Notes, the amendments relating to the 9.00% Notes will become effective.
