        RESOLVED, that the current Section 2.10 of the By-Laws is deleted and

        shareholder and of the beneficial owner, if any, on whose behalf the
        nomination will be made, and (B) the class and number of shares of the

        procedure.

        proposed business up for consideration. Unless and to the extent
        otherwise determined by the presiding officer of the meeting, it shall
        not be necessary to follow Robert's Rules of Order or any other rules of
        parliamentary procedure at the meeting of the shareholders. Following

        officer of the meeting, the presiding officer of the meeting shall have
        the exclusive authority to adjourn the meeting.
