      undersigned's holdings of and transactions in securities issued by

      Section 16(a) of the Securities Exchange Act of 1934 and the rules
      thereunder;

(2)   do and perform any and all acts for and on behalf of the undersigned which
      may be necessary or desirable to complete and execute any such reports on

      thereto, and file such forms with the Securities and Exchange Commission
      and any stock exchange or similar authority; and

(3)   take any other action of any type whatsoever in connection with the
      foregoing which, in the opinion of such attorney-in-fact, may be of
      benefit to, in the best interest of, or legally required by, the
