accordance with Section 16(a) of the Securities Exchange Act of 1934 and the
rules thereunder;

         (2) do and perform any and all acts for and on behalf of the
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 United States
