desirable to complete and execute any Form and timely file such
Form with the United States Securities and Exchange Commission
and any stock exchange or similar authority; and
(3)Take any other action in connection with the foregoing which, in
the opinion of such attorney-in-fact, may be of benefit to, in the best

I grant to each such attorney-in-fact full power and authority to do and
perform any act necessary or proper to be done in the exercise of any

I earlier revoke it in a signed writing delivered to the Office of
the Secretary of the Companies for distribution to the foregoing
attorneys-in-fact.
