With respect to the shares of Common Stock reported herein, each of the Reporting Persons may be deemed to have shared voting and dispositive power or the shared power to direct the vote and disposition of the shares of Common Stock which such Reporting Person may be deemed to beneficially own as set forth above. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by any of the Reporting Persons that it is the beneficial owner of any of the shares of Common Stock referred to herein for the purposes of Section 13(d) of the Act, or for any other purpose, and such beneficial ownership is expressly disclaimed by each Reporting Person, other than each Direct Holder with respect to securities reported as directly held by such Direct Holder.
