    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
    Form 3, 4 or 5, complete and execute any amendment or amendments
    thereto, and timely file such form with the United States 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
    undersigned, it being understood that the documents executed by
    such attorney-in-fact on behalf of the undersigned pursuant to this

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