The principal amount of securities to be purchased through the Maximum Tender Offers will, in the case of the 6.125 percent Notes due March 15, 2007 be equal to the lesser of (i) $300 million and (ii) the difference between $500 million and the principal amount of securities purchased through the Any and All Offers, and in the case of the 5.950 percent Notes due Nov. 1, 2008, be equal to the lesser of (x) $275 million and (y) the difference between $500 million and the principal amount of securities purchased through the Any and All Offers and the principal amount of 6.125 percent Notes due March 15, 2007 accepted for purchase by the Company.

The Any and All Offers are scheduled to expire at 5:00p.m., New York City time, on Dec. 1, 2005, unless extended.

The Maximum Tender Offers are scheduled to expire at 12:00 midnight, New York City time, on December 14, 2005, unless extended. Holders of securities subject to the Maximum Tender Offer must validly tender and not validly withdraw their securities on or before the early tender date, which is 5:00p.m., New York City time, on Dec. 1, 2005, unless extended, to receive the applicable full tender offer consideration. Holders of securities subject to the Maximum Tender Offer who validly tender their securities after the early tender date and on or before the Maximum Tender Offer expiration date will receive the applicable late tender offer consideration, which is the applicable full tender offer consideration minus $10 per $1,000 principal amount of notes tendered by such holder that are accepted for purchase. Holders of securities subject to the Maximum Tender Offer who validly tender their securities on or before the early tender date may not withdraw their securities after the early tender date except in the limited circumstances described fully in the Offer to Purchase. Holders of the securities subject to the Maximum Tender Offer who validly tender their securities after the early tender date but on or before the Maximum Tender Offer expiration date may not withdraw their securities except in the limited circumstances described in the Offer to Purchase.

The applicable full tender offer consideration for each of the $1,000 principal amount of securities tendered and accepted for payment pursuant to the Any and All Offers and the Maximum Tender Offers will be determined in the manner described in the Offer to Purchase by reference to a fixed spread specified for such securities over the yield based on the bid-side price of the applicable U.S. Treasury Security specified on the cover page of the Offer to Purchase, as calculated by the Dealer Managers for the tender offers, at 2:00 p.m. New York City time on Nov. 29, 2005.

In addition to any consideration received, Holders who tender securities will be paid any accrued and unpaid interest calculated up to and not including the applicable settlement date. The settlement date for the Any and All Offers is expected to be Dec. 2, 2005 and the settlement date for the Maximum Tender Offers is expected to be Dec. 15, 2005.
