ITEM 1.01.  Entry into Material Definitive Agreement

  (a)  On December 1, 2005, Ohio Casualty Corporation (the "Company") entered
       into an employment agreement with its President and Chief Executive
       Officer Dan R. Carmichael ("Employment Agreement".)  Pursuant to the
       Employment Agreement, Mr. Carmichael was granted 75,000 restricted
       shares subject to a five-year forfeiture period and 250,000
       Freestanding Stock Appreciation Rights with a three year vesting
       period, both effective as of December 1, 2005.  Mr. Carmichael will
       also receive 100,000 Stock Appreciation Rights with a three year
       vesting period effective as of February 16, 2006.   Additionally, the
       Company also entered into a separate Change in Control agreement with
       Mr. Carmichael, in lieu of a change in control provision which was
       part of Mr. Carmichael's previous employment agreement. The Employment
       Agreement, Restricted Stock Award Agreement, Freestanding Stock
       Appreciation Right Award Agreement and the Change in Control
       agreements are filed as Exhibit 10.1, 10.2, 10.3 and 10.4 hereto, and
       are incorporated herein by reference.

       The Company issued a press release on December 5, 2005 in connection
       with the Employment Agreement, which is posted on the Company's website
       at http://www.ocas.com and is attached hereto as Exhibit 99 and hereby
       incorporated by reference.

  (b)  On December 1, 2005, the Board of Directors also approved an amendment
       to The Ohio Casualty Corporation 1993 Stock Incentive Plan (the "1993
       Plan") to allow the participants under the plan to designate a
       beneficiary to receive or to exercise any awards that are unexercised
       and exercisable upon the participant's death.  Upon approval by the
       Board of Directors, Section 12 of the 1993 Plan has been amended in its
       entirety to read as follows:

            12.  Nontransferability.  Each Stock Option, Stock Appreciation
            Right, Limited Stock Appreciation Right and Restricted Stock Award
            granted under this Program shall not be transferable other than by
            will or the laws of descent and distribution, and shall be
            exercisable, during the Participant's lifetime, only by the
            Participant or the Participant's guardian or legal representative.

            Each Participant may name a "successor in interest" or "successors
            in interest" (who may be named contingently or successively) to
            receive or to exercise any vested Award that is unpaid or
            unexercised and exercisable at or upon the Participant's death.
            Each designation made will revoke all earlier designations made by
            the same Participant, must be made on a form prescribed by the
            Committee and will be effective only when filed in writing with
            the Committee.  If a Participant has not effectively designated a
            successor interest, the deceased Participant's successor in
            interest will be his or her surviving spouse or, if there is no
            surviving spouse, the deceased Participant's estate.

            Whenever the term "successor in interest" or "successors in
            interest" is used in the Plan, it will refer to the person
            identified through the procedures described in this section.
