Certain Longview Clients, including without limitation Reporting Person Family Members and Entities, hold shares of Common Stock. Longview has sole voting and dispositive power over the Common Stock held in Longview Clients' securities accounts and, accordingly, is deemed to be the beneficial owner, for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the "1934 Act"), of the Common Stock held in such accounts. Except for such deemed beneficial ownership, Longview does not own any Common Stock or other securities of the Issuer.

None of such agreements, however, require that such accounts be invested in securities of the Issuer or include in their provisions any terms specifically relating to or varying with the investment of the accounts in securities of the Issuer. Other than (i) the Reporting Persons' investment advisory agreements entered into with Longview, as described above, (ii) Mr. Star's participation in the management of Longview, and (iii) Mr. Grossman's ownership interest in Longview, not individually but solely as the Trustee of the Edward Memorial Trust, none of the Reporting Persons is a party to any contract, arrangement, understanding or relationship (legal or otherwise) with respect to any securities of the Issuer.
