              discretion determine to be required or advisable pursuant to
              Section 16 of the Securities Exchange Act of 1934 (as amended) and
              the rules and regulations promulgated thereunder, or any successor
              laws and regulations, as a consequence of the undersigned's
              ownership, acquisition or disposition of securities of the
              Company; and

       2.     do all acts necessary in order to file such forms with the SEC,
