The reported amounts also do not include an aggregate of 64,178,201 shares of Common Stock beneficially owned by parties to voting agreements (the "Voting Agreement"), by and among the Issuer and the stockholders party thereto. Pursuant to the Voting Agreements, the Reporting Persons may be deemed to be a member of a "group" within the meaning of Rule 13d-5(b) and beneficially own securities beneficially owned by the parties to the Voting Agreements.
