            in accordance with Section 13 of the Securities Exchange Act of
            1934, as amended (the "Exchange Act"), and the rules thereunder, and
            Forms 3, 4, and 5 in accordance with Section 16 of the Exchange Act
            and the rules thereunder;

        2.  do and perform any and all acts for and on behalf of the undersigned

            Schedule 13D or 13G or Form 3, 4, or 5, complete and execute any
            amendment or amendments thereto, and timely file such schedule or

        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

        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
