          The purpose of this convertible note purchase and amendment agreement (this “Agreement”) is to set forth the terms and conditions of (i) the purchase (the “Purchase”) by Counterparty, and sale by Dealer, of Convertible Notes and (ii) the amendment (the “Amendment”) of the confirmation dated as of June 12, 2006, Transaction Reference Number NY-22817, (the “Confirmation”), which supplemented, formed part of and is subject to the Master Terms and Conditions for Convertible Bond Hedging Transactions dated as of June 9, 2006 between Counterparty and Dealer (together with the Confirmation, the “Bond Hedge Documentation”). Capitalized terms used herein but not otherwise defined shall have the meanings assigned to them in the Bond Hedge Documentation.

          1. Convertible Notes Purchase. Dealer agrees to sell, and Counterparty agrees to buy, 200,000 Convertible Notes (in denominations of USD1,000 principal amount) at a price per Convertible Note of $994.50 (the “Per Note Purchase Price”), plus accrued and unpaid interest of $2.02 on such Convertible Note from, and including, June 15, 2010 to, but excluding, the Payment Date, for a total payment of $199,304,166.67 (the “Aggregate Purchase Price”). The parties acknowledge and agree that the Per Note Purchase Price with respect to each Convertible Note of $994.50 equals (i) $1020.00, which represents the payment from Counterparty to Dealer for such Convertible Note, minus (ii) $25.50, which represents the amount of consideration for the Amendment. Closing of the Purchase shall take place on September 22, 2010 (the “Payment Date”), on which such date Counterparty shall pay to Dealer the Aggregate Purchase Price against Dealer’s delivery of the number of Convertible Notes specified above.

          2. Amendment. The parties hereby acknowledge that the Company has agreed on the date hereof to purchase 300,000 Convertible Notes from a third party on the Payment Date (the “Additional Purchase”). Effective upon the payment of the Aggregate Purchase Price and delivery of the number of Convertible Notes specified in paragraph 1 above on the Payment Date, for the purpose of maintaining the notional size of the Transaction to which the Confirmation relates unchanged following the purchase contemplated hereby and the Additional Purchase, the following terms of the Transaction to which the Confirmation relates shall be amended, as follows:

Number of Units:			600,000
Applicable Percentage:			58.333%
