                  that senior financial executives shall abide by a further code

                  integrity with respect to the preparation and reporting of
                  financial information related to the Company. Accordingly,

                  Officer; Chief Financial Officer; head of Finance; Controller;
                  and persons performing similar functions (the "Senior

         5.1.     The Company is committed to complying with all standards of
                  ethical and lawful conduct. This commitment goes beyond
                  compliance. We believe that ethical and lawful conduct is the
                  foundation for our success. Integrity in everything we do is a
                  requirement in all business operations. It is the foundation
                  for mutually beneficial relationships with our customers,
                  suppliers, and communities in which we live and work. All
                  Associates have assigned responsibilities in the operation of
                  our business. Yet, there is another that




                  we all share - responsibility of acting with integrity in all
                  business practices and relationships. This unanimity of
                  purpose allows us to move quickly in exploring new ground; to
                  act boldly in the face of competition; and to take risks
                  whenever they are justified.

         5.2.     This Code is intended as a codification of standards that are
                  reasonably designed to deter wrongdoing and to promote and
                  reinforce the following:

                  5.2.1.   Honest and ethical conduct, including ethical
                           handling of actual or apparent conflicts of interest
                           between personal and professional relationships.

                  5.2.2.   Full, fair, accurate, timely and understandable
                           disclosure in reports and documents that the Company
                           files with or submits to regulatory authorities or
                           releases to the public.

                  5.2.3.   Compliance with applicable governmental laws, rules
                           and regulations.

                  5.2.4.   The prompt reporting to an appropriate person or
                           persons identified in this Code of violations of the
                           Code.

                  disclosure controls and procedures and internal controls to
                  ensure that material information relating to the Company and
                  its consolidated subsidiaries is made known to such Senior
