The aggregate cost of the shares of Common Stock directly held by the Elliott Funds is approximately $1,373,191,701. The Reporting Person may effect purchases of the shares of Common Stock through margin accounts maintained for the Elliott Funds with prime brokers, which extend margin credit as and when required to open or carry positions in their margin accounts, subject to applicable federal margin regulations, stock exchange rules and such firms' credit policies. Positions in the shares of Common Stock may be held in margin accounts and may be pledged as collateral security for the repayment of debit balances in such accounts. Since other securities may be held in such margin accounts, it may not be possible to determine the amounts, if any, of margin used to purchase the shares of Common Stock.

The Reporting Person reduced the economic exposure of the Elliott Funds for portfolio management purposes. The Reporting Person intends for the Elliott Funds to remain significant shareholders of the Issuer based on its confidence that the Issuer's execution of ongoing strategic initiatives will translate to greater profitability, accretive capital-allocation opportunities and shareholder value creation.

See rows (7) through (10) of the cover page to this Schedule 13D for the shares of Common Stock as to which the Reporting Person has the sole or shared power to vote or direct the vote and sole or shared power to dispose or to direct the disposition.

Transactions

The transactions in the shares of Common Stock effected by the Reporting Person during the past sixty (60) days, which were all in the open market, are set forth on Schedule 1 attached hereto and incorporated by reference herein.

Item 4 of the Schedule 13D is incorporated herein by reference. The Elliott Funds have entered into notional principal amount derivative agreements (the "Cash Derivative Agreements") in the form of cash settled swaps with respect to an aggregate of 16,365,000 shares of Common Stock of the Issuer (collectively representing economic exposure comparable to 3.2% of the shares of Common Stock of the Issuer). The Cash Derivative Agreements provide the Elliott Funds with economic results that are comparable to the economic results of ownership but do not provide them or EIM with the power to vote or direct the voting or dispose of or direct the disposition of the shares that are referenced in the Cash Derivative Agreements (such shares, the "Subject Shares"). EIM disclaims beneficial ownership in the Subject Shares. The counterparties to the Cash Derivative Agreements are unaffiliated third-party financial institutions. EIM has combined economic exposure in the Issuer of approximately 13.1% of the shares of Common Stock outstanding. Except as set forth herein, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 hereof and between such persons and any person with respect to any securities of the Issuer, including any class of the Issuer's securities used as a reference security, in connection with any of the following: call options, put options, security-based swaps or any other derivative securities, transfer or voting of any of the securities, finder's fees, joint ventures, loan or option arrangements, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
