and the rules thereunder ("Act");

(2)	do and perform any and all acts for and on behalf of the undersigned which

complete and execute any amendment or amendments thereto, and timely file such

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, including
without limitation preparing, executing and submitting any documents necessary
or appropriate to obtain codes and passwords enabling the undersigned to make

attorney-in-fact's discretion.

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 done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
could do if personally present, with full power of substitution or revocation,
hereby ratifying and confirming all that such attorney-in-fact, or such
attorney-in-fact's substitute or substitutes, shall lawfully do or cause to be
done by virtue of this Power of Attorney and the rights and powers herein

nor is the Company assuming, any of the undersigned's responsibility to comply

transactions in securities issued by the Company, or (ii) the aforenamed
Messers. Battaglioli, Sims, Wright or Ms. Abrams are no longer employed by the

or (iii) this Power of Attorney is earlier revoked by the undersigned in a
signed writing delivered to the foregoing attorneys-in-fact.
