Contact the Board

The Board has established procedures for stockholders to communicate with the Board.

A stockholder may contact the Board by writing to the attention of the Chairperson of the Corporate Governance & Responsibility Committee or the other non-management members of the Board at the Company's principal executive offices at 35 W. Wacker Drive, Chicago, Illinois 60601.

Communications received in writing are distributed to the Chairperson of the Corporate Governance & Responsibility Committee or the Board unless, in the reasonable judgment of the Company's Corporate Secretary, they are considered inappropriate for submission in accordance with standards approved by the Company's independent directors.
