3. take any other action of any type whatsoever in connection

attorney-in-fact's discretion.

The undersigned hereby grants 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
