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

I, J. W. Stewart, state and attest that:

     (1)  To the best of my knowledge, based upon a review of the covered
          reports of BJ Services Company, 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 BJ Services
          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":

          .    the Annual Report on Form 10-K for Fiscal Year ended September
               30, 2001 as filed with the U.S. Securities and Exchange
               Commission on December 18, 2001 of BJ Services Company;

          .    all reports on Form 10-Q, all reports on Form 8-K and all
               definitive proxy materials of BJ Services Company filed with the
               Commission subsequent to the filing of the Form 10-K identified
               above; and

          .    any amendments to any of the foregoing.
