accordance with Section 16(a) of the Exchange Act, and the rules thereunder;

undersigned which may be necessary or desirable to complete the execution of
any such Form 3, 4 or 5 and the timely filing of such form with the SEC and

of the undersigned in the undersigned?s fiduciary and representative
capacity in which the undersigned may be acting.

written notification executed by the undersigned is filed with the SEC
expressly revoking this Limited Power of Attorney.
