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 and execute any such Form 3, 4
or 5, complete and execute any amendment or amendments thereto,  and timely file

stock exchange or similar authority; and

     (3) take any other action of any type  whatsoever  in  connection  with the
foregoing which, 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

     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,
necessary,  or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
