          where two or more persons, corporations or other entities make an offer
          or offers jointly or in concert or intend to exercise jointly or in
          concert any voting rights attaching to the securities to be acquired,
          then the securities owned by each of them shall be included in the calculation
          of the percentage of the outstanding voting securities of the Corporation
          owned by the offeror.
