            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 attorney-in-
            fact on behalf of the undersigned pursuant to this Power of
            Attorney shall be in such form and shall contain such terms
            and conditions as such 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

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

signed writing delivered to the foregoing attorneys-in-fact.
