                   AND CIRCUMSTANCES RELATING TO EXCHANGE ACT
                                     FILINGS

     I, Carlos M. Gutierrez, Chairman of the Board, President and Chief
Executive Officer of Kellogg Company, state and attest that:

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

o   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

o   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 were 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 Kellogg Company'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":

o   The Annual Report on Form 10-K of Kellogg Company for the fiscal year
    ended December 31, 2001 filed with the Commission;

o   All reports on form 10-Q, all reports on Form 8-K and all definitive
    proxy materials of Kellogg Company filed with the Commission
    subsequent to the filing of the Form 10-K identified above; and

o   Any amendments to any of the foregoing.
