Statement Under Oath of Principal Executive Officer
                         and Principal Financial Officer
       Regarding Facts and Circumstances Relating to Exchange Act Filings


I, John W. Conway, state and attest that:

     (1) To the best of my knowledge, based upon a review of the covered reports
of Crown Cork & Seal Company,  Inc., 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 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 the 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":

          - Annual  Report on Form 10-K for the year ended  December 31, 2001 of
          Crown Cork & Seal Company, Inc.;

          - all reports on Form 10-Q, all reports on Form 8-K and all definitive
          proxy  materials  of Crown Cork & Seal  Company,  Inc.  filed with the
          Commission subsequent to the filing of the Form 10-K identified above;
          and

          - any amendments to any of the foregoing.
