with 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 Form 3, 4 or 5, complete and execute
any amendment(s) 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

	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 requisite, necessary or proper to be
