               STATEMENT UNDER OATH OF PRINCIPAL EXECUTIVE OFFICER
                        REGARDING FACTS AND CIRCUMSTANCES
                        RELATING TO EXCHANGE ACT FILINGS

I, Jack M. Greenberg, Chairman of the Board and Chief Executive Officer of
McDonald's Corporation, state and attest that:

(1)  To the best of my knowledge, based upon a review of the covered reports of
     McDonald's Corporation, and, except as corrected or supplemented in a
     subsequent covered report:

     .    no covered report contained an untrue statement of a material fact as
          of the end of the period covered by such report (or in the case of a
          report on Form 8-K or definitive proxy materials, as of the date on
          which it was filed); and

     .    no covered report omitted to state a material fact necessary to make
          the statements in the covered report, in light of the circumstances
          under which they are made, not misleading as of the end of the period
          covered by such report (or in the case of a report on Form 8-K or
          definitive proxy materials, as of the date on which it was filed).

(2)  I have reviewed the contents of this statement with McDonald's
     Corporation's Audit Committee.

(3)  In this statement under oath, each of the following, if filed on or before
     the date of this statement, is a "covered report":

     .    2001 Annual Report on Form 10-K filed with the Commission of
          McDonald's Corporation;

     .    all reports on Form 10-Q, all reports on Form 8-K and all definitive
          proxy materials of McDonald's Corporation filed with the Commission
          subsequent to the filing of the Form 10-K identified above; and

     [_]  any amendments to any of the foregoing.

                                          Subscribed and sworn to before me this
                                          12th day of August 2002.
