Exhibit 99.1


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


I, Dan R. Carmichael, state and attest that:

        (1)  To the best of my knowledge, based upon a review of the covered
        reports of Ohio Casualty 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 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 Ohio Casualty
        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":

        -  Annual Report on Form 10-K for the fiscal year ended December 31,
           2001 of Ohio Casualty Corporation;

        -  All reports on Form 10-Q, all reports on Form 8-K and all
           definitive proxy materials of Ohio Casualty Corporation filed
           with the Commission subsequent to the filing of the Form 10-K
           identified above; and

        -  Any amendments to any of the foregoing.
