                                     NOTE


                  The answers to this statement insofar as such
            answers relate to what persons have been underwriters for
            any securities of the Obligor within three years prior to
            the date of filing this statement, or are owners of 10
            percent or more of the voting securities of the Obligor,
            or affiliates, are based upon information in--writing
            furnished to the Trustee by the Obligor, and upon which
            the Trustee has relied for the purposes of this document.

                  Inasmuch as this statement is filed prior to the
            determination of underwriters of the indenture
            securities, the answers to Items 5, 7, 9, and 14 are
            based on incomplete information.  To the best of our
            knowledge and belief, however, there is no person, firm
            or corporation ordinarily engaged in underwriting
            securities:

                        1)   which is an affiliate of the Trustee;

                        2)   of which any director or executive officer
                             of the Trustee is a director, partner,
                             employee, appointee or representative;

                        3)   which individually owns, beneficially, or
                             whose directors, partners and executive
                             officers collectively own, beneficially,
                             more than 1 percent of the outstanding
                             Common Stock of the Trustee; or,

                        4)   whose securities are owned beneficially by
                             the Trustee or held by the Trustee as
                             collateral security for obligations in
                             default.

                  This statement may therefore be considered as
            correct unless amended contemporaneously with the filing
            by the Obligor of the Amendment to its Registration
            Statement disclosing underwriters for the indenture
            securities.


Item 14.    AFFILIATIONS WITH THE UNDERWRITERS

                  To the best knowledge and belief of the Trustee no
            underwriter of securities of the Obligor is an affiliate
            of the Trustee.

                              (See Note, page 6.)



Item 15.    FOREIGN TRUSTEE

                  The Trustee is not a foreign trustee but a national
            banking association organized and existing under the
            banking laws of the United States of America.



Item 16.    LIST OF EXHIBITS

            Exhibit (1)         The Articles of Association of the
