        <footnote id="F1">The transaction was the tender of all 28,023,788 shares of the Issuer Common Stock beneficially owned by the Reporting Person pursuant to the Tender Offer by the Issuer which expired on May 24, 2007. On May 25, 2007, the Issuer announced that the Tender Offer was oversubscribed. Pursuant to the terms of the Tender Offer, the Issuer will purchase up to 126,000,000 shares of Issuer Common Stock on a pro rata basis. The Issuer is expected to announce the pro rata amounts accepted by the Issuer in the near future, and upon such notification by the Issuer as to the actual number of shares purchased in the Tender Offer, the Reporting Person will file an amendment to this Form 4 reporting the number of its shares sold in the Tender Offer and the remaining number beneficially owned thereafter.</footnote>
