Exhibit 10.4 		 THE OHIO CASUALTY INSURANCE COMPANY 			 BENEFIT EQUALIZATION PLAN 	 Adopted as of August 16, 1990 Retroactive to July 1, 1990 June 2002 				 -1- 				 FORWARD Effective as of July 1, 1990, the Ohio Casualty Insurance Company has adopted The Ohio Casualty Insurance Company Equalization Plan (the "Plan") for the benefit of certain of its employees. It is intended that the "excess benefits" provided under the Plan be an unfunded "excess benefit plan" as that term is defined in Section 3(36) of the Employee Retirement Income Security Act of 1974, and that the "supplemental benefits" provided under the Plan be an unfunded deferred compensation plan for "a select group of management or highly compensated employees" as that term is used in the Employee Retirement Income Security Act of 1974. The purpose of the Plan is to provide eligible participants and their Beneficiaries with the amount of Company-provided benefits that would have been provided under the Employees Retirement Plan of The Ohio Casualty Insurance Company ("Retirement Plan") but for the limitations on benefits imposed under Section 415 of the Internal Revenue Code and the limitation on compensation for purposes of Retirement Plan imposed by Section 401(a)(17) of such Code. 				 SECTION ONE 1.1 Except to the extent otherwise indicated herein, and to the extent otherwise inappropriate in the context, the definitions contained in Section 1 of the Retirement Plan are application under the Plan. 1.2 "Actuarial Equivalent Present Value" means, with respect to Excess Benefits and/or Supplemental Benefits, the lump sum actuarial present value of the aggregate amount of such Excess Benefits and/or Supplemental Benefits payable to or with respect to a participant in accordance with the terms of the Plan. Such lump sum actuarial equivalent present value shall be determined on the basis of (a) the same mortality table used for the most current 	 accounting valuation for the Retirement Plan, and (b) the PBGC interest rate then in effect for purposes of 	 valuing immediate annuities for terminating plans in 	 accordance with requirements of Section 4062 of ERISA, 	 adjusted by multiplying such rate by (1 minus the marginal 	 tax rate {reflecting, June 2002 	 for this purpose, the combined Ohio and federal marginal tax 	 rates}), and further adjusted by rounding such rate as so 	 determined to the nearest 1/4%. 1.3 "Beneficiary" means the beneficiary or beneficiaries (who may be any one or more members of his family or other persons, executors, administrators, any trust foundation or other entity) designated by the participant, at such time and in such manner as the Company shall determine, to receive any benefits payable hereunder after the death of the participant as provided herein. If no beneficiary has been designated, or if all designated beneficiaries have predeceased the participant, the Beneficiary shall be the participant's legal representative or, if no legal representative shall have been appointed within six (6) months after the death of the participant, then to and among such one or more of the spouse and blood relatives of such deceased participant as the Company may in its sole discretion appoint. 1.4 "Board of Directors" mean the Board of Directors of The Ohio Casualty Insurance Company. 1.5 "Company" means The Ohio Casualty Insurance Company, or any entity which shall be a successor to it in ownership of substantially all of its assets and which shall assume all of its rights and obligations under the Plan. 1.6 "Excess Benefit" means the excess, if any, of (i) the retirement benefit which would have been payable to or with respect to a participant at his benefit commencement date under the Retirement Plan had the limitations on benefits imposed by Section 14 of the Retirement Plan not been applicable over (ii) the retirement benefit payable to or with respect to the participant at his benefit commencement date under the Retirement Plan. 1.7 "Plan" means The Ohio Casualty Insurance Company Benefit Equalization Plan as from time to time in effect. 1.8 "Retirement Plan" means the Employees Retirement Plan of The Ohio Casualty Insurance Company. 1.9 "Supplemental Benefit" means the excess, if any, of (i) the retirement benefit that would have been payable to or with respect to a participant at his benefit commencement date under the Retirement Plan had the limitations on benefits imposed by Section 14 of the Retirement Plan not been applicable and the participant's Compensation under the Retirement Plan been inclusive of amounts which are disregarded by reason of exceeding the compensation limit referred to in subsection 1.7 of the Retirement Plan (as adjusted in accordance with Section 401(a)(17) of the Internal Revenue Code), over (ii) the sum of (a) the retirement benefit payable to or with respect to the participant at his benefit commencement date under the Retirement Plan and (b) any Excess Benefit payable under this Plan.

(b) No portion of any Excess Benefit or Supplemental Benefit 	 payable hereunder (or, if applicable, the Actuarial 	 Equivalent Present Value thereof), shall be deemed to be an 	 asset of this Plan; at all times, any funds used to pay 	 benefits under the Plan shall be derived from the general 	 assets of the Company, subject to claims of the Company's 	 creditors.

(d) To the extent that any supplemental retirement benefits are 	 payable to a participant under an employment or other 	 agreement between the participant and the Company, the 	 benefits otherwise payable hereunder shall be reduced by the 	 Actuarial Equivalent Present Value of such payments. (e) In the event that the Retirement Plan shall be terminated, 	 accrual and payment of benefits under the Plan shall cease, 	 unless the Company shall otherwise specifically provide by 	 action of its Board of Directors at the time of termination 	 of the Retirement Plan or at a later date.
