         any provision contained in this Certificate of Incorporation, in the
         manner now or hereafter prescribed by statute, and all rights conferred
         upon stockholders herein are granted subject to this reservation.

10.      A director of the corporation shall not be personally liable to the
         corporation or its stockholders for monetary damages for breach of
