      4.  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, 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 may approve in such attorney-in-

      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
