	(2) 	do and perform any and all acts for and on my
behalf that may be necessary or desirable to complete and
execute any such Form 3, 4 or 5 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

such attorney-in-fact on my behalf pursuant to this Power
of Attorney shall be in such form and shall contain such
terms and conditions as such attorney-in-fact may approve
in such attorney-in-fact's discretion.

	I hereby grant 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 done
