		       OHIO CASUALTY INSURANCE COMPANY

	   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).

				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.

				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.

			       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.

	(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.

	Accounts.  During the existence of this Plan, the Accounts shall be
	credited monthly, commencing at the end of the first month in which

	Compensation for that plan year is in excess of the Code Section
