Securities Exchange Act of 1934, as amended, 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 Securities and Exchange Commission and any

(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

       The undersigned hereby grants to the above attorneys-in-fact full power and authority to do and
