Pursuant to Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), a beneficial owner of a security includes any person who, directly or indirectly, through any contract, arrangement, understanding, relationship, or otherwise has or shares: (i) voting power, which includes the power to vote, or to direct the voting of shares; and (ii) investment power, which includes the power to dispose or direct the disposition of shares. Certain shares may be deemed to be beneficially owned by more than one person (if, for example, persons share the power to vote or the power to dispose of the shares). In addition, shares are deemed to be beneficially owned by a person if the person has the right to acquire the shares (for example, upon exercise of an option) within 60 days of the date as of which the information is provided. In computing the percentage ownership of the Reporting Person, the amount of shares outstanding is deemed to include the amount of shares beneficially owned by the Reporting Person (and only the Reporting Person) by reason of these acquisition rights. As a result, the percentage of outstanding shares of the Reporting Person as shown in this statement on Schedule 13D does not necessarily reflect the Reporting Person's actual ownership or voting power with respect to the number of common shares actually outstanding.

(2)   Based on 235,624,362 shares of the Issuer's common stock issued and outstanding as of the close of business on July 15, 2011.
