Exhibit 10-2 		 OHIO CASUALTY INSURANCE COMPANY 		 SUPPLEMENTAL EXECUTIVE SAVINGS PLAN 	 Adopted August 16, 1990 Retroactive to January 1, 1989 			Amended Effective June 1, 2002 April 1, 2002 				 FORWARD Effective as of January 1, 1989, The Ohio Casualty Insurance Company has adopted The Ohio Casualty Insurance Company Supplemental Executive Savings Plan (the "Plan") for the benefit of certain of its employees. It is intended that the Plan be a 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. Beginning in 1989, under the provisions of Section 401(a)(17) of the Internal Revenue Code, certain participants in The Ohio Casualty Insurance Company Employee Savings Plan ("Savings Plan") have become subject to a maximum limitation on Compensation that can be counted under the Savings Plan. The purpose of this Plan is to protect any affected employee from the direct loss of Company provided deferred compensation which would otherwise result from the limitation on Compensation imposed by Code Section 401(a)(17). April 1, 2002 1 				SECTION ONE 				Definitions 				----------- 1.1 Except to the extent otherwise indicated herein, and to the extent 	otherwise inappropriate to the context, the definitions contained in 	Section 1 of the Savings Plan are applicable under the Plan. 1.2 "Board of Directors" means the Board of Directors of The Ohio 	Casualty Insurance Company. 1.3 "Company" means The Ohio Casualty Insurance Company, or any entity 	which shall be successor to it in ownership of substantially all of 	its assets and which shall assume all of its rights and obligations 	under the Plan. 1.4 "Plan" means The Ohio Casualty Insurance Company Supplemental 	Executive Savings Plan as from time to time in effect. 1.5 "Savings Plan" means The Ohio Casualty Insurance Company Employee 	Savings Plan. 1.6 "Supplemental Benefit" for each month means the excess, if any, of 	(i) the Company Contribution that would have been made to the 	Company Contribution Account to or with respect to a Participant that 	month under the Savings Plan had the Participant's Compensation under 	the Savings Plan been inclusive of amounts which are disregarded by 	reason of the cost-of-living-adjusted $200,000 limit imposed under Code 	Section 401(a)(17), referred to in subsection 1.12 of the Savings 	Plan, over (ii) the Company Contribution allocated to the Participant 	under the Savings Plan that month. In determining the amount of a 	Supplemental Benefit, it shall be assumed that the Participant would 	have contributed under the Savings Plan on his Compensation in excess 	of the Code Section 401(a)(17) limit at the same rate as he 	contributed on his Compensation up to that limit. April 1, 2002 2 				SECTION TWO 			 Participation 			 ------------- Participation in the Plan shall be limited to those Participants in the Savings Plan and their beneficiaries who, as a result of the limitation on Compensation which may be taken into account under the Savings Plan by reason of Section 401(a)(17) of the Internal Revenue Code, receive or will receive a lesser Company Contribution under the Savings Plan than otherwise would be paid or payable in the absence of such limitation. April 1, 2002 3 			 SECTION THREE 			 Supplemental Benefits 			 --------------------- 3.1 Vesting in Supplemental Benefits 	-------------------------------- 	A Participant shall vest in each Supplemental Benefit credited to 	him under this Plan in the same manner and at the same time that 	he would have become vested in that amount under the Savings Plan 	had there been no Code Section 401(a)(17) limitation. 3.2 General Provisions 	------------------ 	(a) The Company may make provisions for, or arrange for, the 	 advance funding of any Supplemental Benefits payable 	 hereunder to the extent that it, in its sole discretion, 	 deems necessary or appropriate, provided, however that no 	 such provision or arrangement shall be made which would cause 	 any such benefits to be "funded" (i.e., taxable prior to 	 actual receipt) for federal income tax purposes. 	(b) In the event that the Company shall decide to make provision 	 for advance funding on its books against the future expense of 	 Supplemental Benefit payments, such decision shall under no 	 circumstances result in any amount being 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. 	(c) No withdrawals or loans are permitted from the Plan during 	 employment. 	(d) To the extent permitted by law, none of the benefits payable 	 under this Plan shall be subject in any manner to anticipation, 	 alienation, sale, transfer, assignment, pledge or encumbrance. 	 No benefits hereunder shall be subject to the claims of creditors 	 of the Participant or his beneficiary or to legal process. 	 Benefits hereunder, and any Supplemental Benefit Accounts, are 	 general obligations only of the Company and create no specific 	 asset or assets of the Company against which any individual may 	 claim any interest. April 1, 2002 4 	(e) The Supplemental Benefit with respect to a Participant shall 	 be paid to the Participant, or if he is deceased, his 	 designated beneficiary, or if none, his estate, in either 	 (i) whole shares of Ohio Casualty Corporation common stock, 	 with fractional shares paid in cash provided the market value 	 is 25 shares or more, or (ii) in a cash lump sum if the 	 market value is less than 25 shares. Effective April 1, 	 2002 all payments made under this Plan shall be in the form 	 of a lump sum cash distribution. The payment of such benefits 	 shall be made from the general assets of the Company. 	 The Participant's account will be valued and processed for 	 final distribution on the last trading day of the month in 	 which the Participant elected a final distribution from the 	 Savings Plan. Effective June 1, 2002 the Participant's account 	 will be valued and processed for final distribution on the last 	 trading day of the month in which the Participant's employment 	 with the Company has terminated. 	 Notwithstanding the foregoing to the contrary, effective June 	 1, 2002, a participant whose employment with the Company 	 terminated before June 1, 2002 and who has not received a final 	 distribution of such participant's account under this Plan as 	 of June 1, 2002 (a "pre-June1, 2002 terminated participant") 	 may elect the month end valuation date when payment of such 	 final distribution will occur; provided that such final 	 distribution occurs no later than November 30, 2002 or if 	 November 30, 2002 is not a trading day, the preceding trading 	 day in November, 2002. Except as described in the preceding 	 sentence, such pre-June 1, 2002 terminated participant's 	 account will be valued and processed for final distribution on 	 the last trading day of the month in which such participant's 	 election was made. If such pre-June 1, 2002 terminated 	 participant fails to elect to receive a final distribution of 	 such participant's account under this Plan before November 30, 	 2002, any such remaining amounts credited to such participant's 	 account shall be valued and processed on November 30, 2002 or, 	 if November 30, 2002 is not a trading day, the preceding 	 trading day in November, 2002. 	(f) In the event that the Savings Plan or this Plan shall be 	 terminated, no further vesting in Supplemental Benefits shall 	 occur hereunder, unless the Company shall otherwise 	 specifically provide by action of its Board of Directors at 	 the time of termination of such Plan. However, any Supplemental 	 Benefits already vested shall remain vested and shall be payable 	 under this Plan in accordance with the foregoing provisions of 	 this Section Three. 3.3 Allocation of Supplemental Benefit 	---------------------------------- April 1, 2002 5 	Each month's Supplemental Benefit shall be converted into performance 	shares (to the nearest one-thousandth of a share) by dividing the 	Supplemental Benefit that month by the closing market value of a 	common share of the Company's stock on the last trading day of that 	month. Each performance share shall be deemed equivalent in value to 	one share of the Company's common stock. However, performance shares 	shall not entitle the recipient to any voting rights with respect to 	such shares. 	As of the last day of the month in which dividends are payable on 	the Company's stock, each Participant's performance shares shall be 	increased by additional performance shares (to the nearest one- 	thousandth of a share) determined by dividing the cash value of the 	dividend (i.e., the product of the dividend rate per share on the 	dividend date times the performance shares then credited to the 	Participant's account) by the closing market value of a common 	share of the Company's stock on the last trading day of the month 	the dividend was paid. 	In the event there is any change in the common shares of the Company 	resulting from a stock split, combination or exchange of shares, 	merger, consolidation, or other reorganization or capital adjustment 	(other than a dividend in shares taken into account under the 	preceding sentence), equitable proportionate adjustment shall be 	made immediately by the Committee to the performance shares credited 	to the Supplemental Benefit Accounts under this Plan. April 1, 2002 6 			 SECTION FOUR 			 Administration 			 -------------- 4.1 Plan Administrator 	------------------ 	The Ohio Casualty Insurance Company shall be the "administrator" of 	the Plan within the meaning of ERISA. 4.2 Retirement Committee 	-------------------- 	Subject to the provisions of Section 4.1, the Committee of the 	Retirement Plan shall be vested with the general administration of 	the Plan. The Committee shall have the exclusive right to interpret 	the Plan. The decisions, actions and records of the Committee shall 	be conclusive and binding upon the Company and all persons having or 	claiming to have any right or interest in or under the Plan. 4.3 Claims Procedure 	---------------- 	Any claims procedures outlined in the Savings Plan shall apply for 	purposes of administering claims under this Plan. April 1, 2002 7 			 SECTION FIVE 			 Accounts 			 -------- 5.1 Supplemental Benefit Accounts 	----------------------------- 	For the purpose of reflecting the Supplemental Benefits of each 	Participant, a general ledger account shall be established for each 	eligible Participant, referred to herein as the Supplemental Benefit 	Accounts. During the existence of this Plan, the Accounts shall be 	credited monthly, commencing at the end of the first month in which 	the Participant reaches the Compensation limit under the Savings 	Plan and for each subsequent month in which the Participant's 	Compensation for that plan year is in excess of the Code Section 	401(a)(17) limit. April 1, 2002 8 			 SECTION SIX 			Amendment and Termination 			------------------------- 6.1 Amendment of the Plan 	--------------------- 	Subject to the provisions of Section 6.3, the Plan may be wholly or 	partially amended or otherwise modified at any time by the Board of 	Directors. 6.2 Termination of the Plan 	----------------------- 	Subject to the provisions of Section 6.3, the Plan may be terminated 	at any time by the Board of Directors. 6.3 No Impairment of Benefits 	------------------------- 	Notwithstanding the provisions of Section 6.1 and 6.2, no amendment 	to or termination of the Plan shall impair any vested rights to 	benefits which have accrued hereunder prior to such amendment or 	termination.
