(2)  do and perform any and all acts for and on behalf of the undersigned that
     may be necessary or desirable to complete and execute any such Form 3, 4 or
     5, complete and execute any amendment or amendments thereto, 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 of any type whatsoever in connection with the
     foregoing that, in the opinion of such 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 such attorney-in- fact on
     behalf of the undersigned pursuant to this Power of Attorney shall be in

The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
