      such form and will contain such information as the Attorney-in-Fact, in
      his or her discretion, deems necessary or desirable;

      c)Neither the Company nor the Attorney-in-Fact assumes any liability
      for the undersigned's responsibility to comply with the requirements of
      Section 13 or Section 16 of the Exchange Act or Rule 144, any liability
      of the undersigned for any failure to comply with such requirements, or
      any liability of the undersigned for disgorgement of profits under
      Section 16(b) of the Exchange Act; and

      d)This Power of Attorney does not relieve the undersigned from

      the Exchange Act.

The undersigned hereby grants to the Attorney-in-Fact full power and authority
to do and perform each and every act and thing requisite, necessary, or
advisable to be done in connection with the foregoing, as fully, to all intents
and purposes, as the undersigned might or could do in person, hereby ratifying
and confirming all that the Attorney-in-Fact, or his or her substitute or
substitutes, shall lawfully do or cause to be done by authority of this Power
of Attorney.

This Power of Attorney shall remain in full force and effect until the

signed writing delivered to the Attorney-in-Fact. This Power of Attorney
