and the rules thereunder, and any other forms or reports the undersigned may be
required to file in connection with the undersigned's ownership, acquisition, or
disposition of securities of the Company;

(3)       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 Form 3, 4,
or 5, or other form or report, and timely file such form or report with the
United States Securities and Exchange Commission and any stock exchange or
similar authority; and

(4)       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 undersigned, it being
understood that the documents executed by such attorney-in-fact on behalf of the

           The undersigned hereby grants to each such attorney-in-fact full
power and authority to do and perform any and every act and thing whatsoever
