Holders of Notes that validly tendered their Notes on or prior to the Early Tender Date and whose Notes have been accepted for purchase are entitled to receive U.S.$991.250 per U.S.$1,000 principal amount of 2030 Notes, U.S.$1,012.625 per U.S.$1,000 principal amount of 2029 Notes and U.S.$911.875 per U.S.$1,000 principal amount of 2031 Notes accepted for purchase, which includes, in each case, an early tender premium equal to U.S.$30.00 per U.S.$1,000 principal amount of Notes accepted for purchase. Holders of Notes who validly tendered their Notes on or prior to the Early Tender Date and whose Notes have been accepted for purchase will also receive accrued and unpaid interest on their accepted Notes from the last interest payment date to, but not including, the Early Settlement Date. The total cash payment to purchase the accepted Notes on the Early Settlement Date will be approximately U.S.$419,293,717.35.
