          Commission, any stock exchange or similar authority and such other
          person or agency as the attorney-in-fact shall deem appropriate; and

     3.   take any other action of any type whatsoever in connection with the
          foregoing which, in the opinion of the attorney-in-fact, may be of
          benefit to, in the best interest of, or legally required by, the
          undersigned, it being understood that the documents executed by the
          attorney-in-fact on behalf of the undersigned pursuant to this Power
          of Attorney shall be in such form and contain such terms and
          conditions as the attorney-in-fact may approve in such
          attorney-in-fact's discretion.

     The undersigned hereby grants to each of the foregoing attorneys-in-fact
full power and authority to do and perform any and every act and thing

undersigned, are not assuming, nor is the Company assuming, any of the
undersigned's responsibilities to comply with Section 16(a) of the Exchange Act.

     This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4 and 5 with respect to the
