In addition, Prescott Capital serves as the general partner of the Prescott Accounts and may direct the vote and disposition of the 900 shares of Common Stock held by the Prescott Accounts. As the principal of Prescott Capital, Mr. Frohlich may direct the vote and disposition of the 1,583,891 shares of Common Stock held by (i) Prescott Master Fund and (ii) the Prescott Accounts.
