	(3)	Do and perform any and all acts for and on behalf of the undersigned that
may be necessary or desirable to prepare and execute any such Form 3, 4 or 5

	(4)	Take any other action of any type whatsoever in connection with the
foregoing that, in the opinion of such attorney-in-fact, may be of benefit to,

	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,
