The Tender Offers were made pursuant to an Offer to Purchase dated February 26, 2013 (as amended and supplemented, the "Offer to Purchase") and the related Letter of Transmittal dated February 26, 2013 (as amended and supplemented, the "Letter of Transmittal"), which set forth a complete description of the terms of the Tender Offers.Holders who validly tendered their Securities at or prior to 5:00 p.m., New York City time, on March 11, 2013 (the "Early Tender Date") are eligible to receive the Total Consideration (as defined below). The Tender Offers will expire at 11:59 p.m., New York City time, on March 25, 2013 (such date and time, as it may be extended, the "Expiration Date"), unless earlier terminated. Tendered Securities of a series may no longer be withdrawn from the Tender Offers.The "Total Consideration" for each $1,000 principal amount of each series of the Securities validly tendered at or prior to the Early Tender Date and accepted for purchase pursuant to the Tender Offers and the "Tender Offer Consideration" for each $1,000 principal amount of each series of Securities validly tendered after the Early Tender Date but at or prior to the Expiration Date and accepted for purchase pursuant to the Tender Offers, are set forth in the table below. The Total Consideration for each $1,000 principal amount of each series of Securities validly tendered at or prior to the Early Tender Date and accepted for purchase pursuant to the Tender Offers was determined by reference to the applicable fixed spread specified in the table below for the Securities over the yield based on the bid-side price of the applicable Reference U.S. Treasury Security specified in the table below, as calculated by the dealer managers for the Tender Offers at 9:30 a.m., New York City time, today. The Total Consideration includes the early tender premium of $30.00 per $1,000 principal amount of Securities. Holders who validly tender Securities after the Early Tender Date but at or prior to the Expiration Date and whose Securities are accepted for purchase will receive the applicable Tender Offer Consideration, which is the Total Consideration less the early tender premium of $30.00 per $1,000 principal amount of Securities.Title of SecurityCUSIP Number Acceptance Priority LevelPrincipal Amount OutstandingMaximum Principal AmountReference U.S.Treasury SecurityReference YieldFixed Spread(basis points)Total Consideration (1)Tender Offer Consideration(1)6.0% Notes due October 1, 2015$249,560,000$125,000,0000.25% U.S. Treasury Note due January 31, 20158.95% Notes due July 1, 2017$249,400,0000.875% U.S. Treasury Note due January 31, 2018(1) Per $1,000 principal amount of SecuritiesSecurities that are tendered and accepted for purchase will be settled only on the settlement date, which will promptly follow the Expiration Date and is expected to be March 26, 2013.In addition to the applicable Tender Offer Consideration or the Total Consideration, as the case may be, all Securities accepted for purchase will also receive accrued and unpaid interest on thoseMedia Contacts
