      The following information updates and supersedes the information in our Prospectus Supplement (the “Prospectus Supplement”), Subject to Completion dated May 10, 2006, To Prospectus Dated May 10, 2006. In addition, the information set forth below under “Capitalization” supersedes and replaces in its entirety the information set forth in the Prospectus Supplement under the caption “Capitalization.”
Update on Offering Size
      We are offering $190.0 million aggregate principal amount (with an additional $28.5 million should the underwriter’s option to purchase additional notes be fully exercised) of 2.50% Convertible Senior Subordinated Notes due 2011.
Use of Proceeds
      We expect to receive net proceeds from this offering of $183.9 million (excluding the underwriter’s option to purchase additional notes), after deducting the underwriting discounts and commissions and our estimated offering expenses. We intend to use the net proceeds from the offering to redeem, repurchase or otherwise retire $176.5 million of our $200.0 million aggregate principal amount outstanding of our 10.5% senior subordinated notes due 2009 (together with the payment of the related premium, accrued and unpaid interest to and including the redemption date and related fees and expenses). In the event the underwriter exercises its option to purchase additional notes in full, we intend to use the proceeds to redeem, repurchase or otherwise retire the remaining amount of notes outstanding of our 10.5% senior subordinated notes due 2009, with any remainder (an estimated $3.2 million), to retire other debt or for general corporate or working capital purposes.
Update on Concurrent Offering Size and Use of Proceeds
      We are offering $400.0 million aggregate principal amount of our 9.25% senior notes due 2016 in the concurrent offering. We intend to use the net proceeds from the concurrent offering to purchase the $349.4 million of 9.25% senior notes in the tender offer (including the payment of the tender premium, accrued and unpaid interest, the early tender payment and related fees and expenses), with the remainder (an estimated $13.1 million) to repurchase remaining 9.25% senior notes that may be tendered, subject to the cap, to retire other debt or for general corporate or working capital purposes. As of May 9, 2006, holders of $349.4 million in aggregate principal amount of 9.25% notes have tendered in the tender offer. We have increased the size of the tender offer to $360 million.
Outstanding Debt and Ranking
      As of March 31, 2006, assuming completion of the concurrent transactions, we would have had approximately $1,464.8 million of senior debt (approximately $300 million of which would have been secured), $213.5 million of senior subordinated debt and approximately $378.4 million of subordinated debt.

Settlement Cycle
      We expect that delivery of the notes will be made against payment therefor on or about May 26, 2006, which will be the 11th business day following the date of pricing of the notes (such settlement cycle being herein referred to as “T + 11)”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, or Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the date of pricing or the next seven succeeding business days will be required, by virtue of the fact that the notes initially will settle T + 11, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to trade notes on the date of pricing or the next three succeeding business days should consult their own advisor.

For purposes of this table, we have assumed that such notes are redeemed on the 60th day following this offering at that price.
