Revocation of Consents
All properly completed and executed Letters of Consent received prior to the Consent Deadline will be counted, notwithstanding any transfer of any Notes to which such Letter of Consent relates, unless the Tabulation Agent receives from a Holder (or a subsequent holder that has received a proxy from the relevant Holder) a written notice of revocation bearing a date later than the date of the prior Letter of Consent at any time prior to the earlier of the receipt of Requisite Consents for a particular series of Notes to which such Letter of Consent relates and 5:00 p.m., New York City time, on November 7, 2006 (such earlier date, the Revocation Date). A notice of revocation shall only be effective if it complies with the procedures for revocation set forth in the Letter of Consent; provided, however, any notice of revocation received after the Revocation Date will not be given effect. A consent to the Proposed Amendment and Waiver by a Holder will bind the Holder and every subsequent holder of such Notes or portion of such Notes, even if notation of the consent is not made on such Notes.
A transfer of Notes after the Record Date must be accompanied by a duly executed proxy from the relevant Holder if the subsequent transferee is to have revocation rights with respect to the consent to the Proposed Amendment and Waiver. To be effective, a notice of revocation must be in writing, must contain the name of the Holder and the aggregate principal amount of the Notes to which it relates and must be (i) signed in the same manner as the original Letter of Consent or (ii) accompanied by a duly executed proxy or other authorization (in form satisfactory to us). All revocations of consents must be sent to the Tabulation Agent at its address set forth in the Letter of Consent.
