Except for the extension of the Expiration Date, all of the other terms and conditions of the tender offer and consent solicitation remain unchanged.

To date, holders of approximately 100% of the outstanding aggregate principal amount of the Senior Secured Notes, holders of approximately 93.41% of the outstanding aggregate principal amount of the Senior Subordinated Notes and holders of approximately 97.96% of the outstanding aggregate principal amount of the Debentures, have tendered their outstanding Notes and delivered related consents pursuant to the tender offers and consent solicitations. As previously announced, the Issuers received the requisite consents from the registered holders of the Notes to amend the indentures governing the Notes. The last day that holders of Notes could have withdrawn tendered Notes and revoked the related consents was as of 5:00 p.m. New York City time on May 2, 2007 (the "Consent Date"). As a result, tendered Notes and related consents may no longer be withdrawn or revoked.

If all conditions to the tender offer and consent solicitation are satisfied, holders of the Notes who validly tendered their Notes pursuant to the tender offer and validly delivered their consents pursuant to the consent solicitation by the Consent Date and did not validly withdraw their Notes or revoke their consents by such date, will be paid a consideration of $1,057.53, for each $1,000 principal amount outstanding of Senior Secured Notes, $1,013.50 for each $1,000 principal amount outstanding of Senior Subordinated Notes and $1,012.50 for each $1,000 principal amount outstanding of Debentures, in each case, in addition to a consent payment of $30 per $1,000 outstanding principal amount of Notes tendered and accepted in the tender offers. Holders who validly tender their Notes after the Consent Date will not receive the consent payment. In addition, holders who validly tender and do not validly withdraw their Notes in the tender offer will receive accrued and unpaid interest from the last interest payment date up to, but not including, the applicable date of payment.
