     Directors of the party that appointed such member. Initial appointments
     shall be made within fourteen (14) days of the date of this Agreement. A
     member of the Committee may be removed at any time, with or without cause,
     by the party that appointed such member. The Committee shall meet each
     quarter, or otherwise at the call of the chairperson to review, coordinate,
     and discuss issues regarding the Promotional Program. In addition, the
     Committee shall review and resolve issues pertaining to this Agreement. The
     members of the Committee will use reasonable efforts to reach consensus on
     all decisions.
