to, in the best interest of, or legally required by, the undersigned, it being
understood that the documents executed by such attorney-in-fact on behalf of
the undersigned pursuant to this Power of Attorney shall be in such form and

       		The undersigned hereby grants to each such attorney-in-fact

delivered to the foregoing attorneys-in-fact.

       	 	This power of attorney revokes my previous power of attorney
