ITEM 1.01.  Entry into a Material Definitive Agreement
- ---------
(a)  On February 16, 2006, the Board of Directors of The Ohio Casualty
     Corporation (the "Corporation") approved The Ohio Casualty Insurance
     Company 2006 Senior Officer Annual Incentive Program (the "Program").
     The Program is designed to give eligible participants the opportunity to
     receive an incentive bonus based on corporate operating income and
     controllable expense ratio, as well as business unit and individual
     performance.  Incentive bonuses for officers in the Company's Personal
     Lines, Commercial Lines and Specialty Lines (collectively, "Business
     Units") will be based 50% on corporate operating income and controllable
     expense ratio and the remaining 50% on their respective business unit's
     combined ratio and premium.  For all other officers, the incentive will be
     based on corporate operating income and controllable expense ratio.  A
     copy of the Program is attached hereto as Exhibit 10.1 and hereby
     incorporated by reference.

(b)  On February 16, 2006, the Board of Directors of the Corporation also
     approved the 2006 Officer Long-Term Incentive award which includes
     performance based stock units and cash for the performance period
     beginning January 1, 2006 and ending on December 31, 2008.  The payout
     under this award is based on a combination of two measures.  The payout
     will first be calculated based on cumulative after tax operating income
     with subsequent adjustment up or down based on the Company's total
     shareholder return during the performance period compared to the total
     shareholder returns of a pre-determined group of 17 industry peers for
     the same period.  Included as Exhibit 10.2 and incorporated by reference
     to this Item 101(b) is the schedule of the potential payouts under the
     2006 Officer Long-Term Incentive Award for executive officers of the
     Corporation.  The form of agreement for the 2006 Long-Term Incentive
     Award will be filed once available as an amendment to this Form 8-K.

(c)  On February 16, 2006, the Board of Directors of Ohio Casualty
     Corporation awarded to Mr. Dan R. Carmichael, President and Chief
     Executive Officer, a Freestanding Stock Appreciation Right to purchase
     100,000 shares of Ohio Casualty Corporation at an exercise price of
     $31.51 per share, which was the fair market value of the Company's
     shares as of February 16, 2006.  This award was made pursuant to the
     terms of Mr. Carmichael's employment agreement with the Company.  The
     Freestanding Stock Appreciation Rights agreement is substantially in
     the form of the Freestanding Stock Appreciation Rights agreement included
     as exhibit 10.3 to the Form 8-K filed by the Company on December 5, 2005
     and is hereby incorporated by reference.
