			  Report of Independent Auditors


We have audited the accompanying statements of net assets available for
benefits of The Ohio Casualty Insurance Company Employee Savings Plan ("the
Plan") as of December 31, 2002 and 2001, and the related statement of changes
in net assets available for benefits for the year then ended.  These
financial statements are the responsibility of the Plan's management.  Our
responsibility is to express an opinion on these financial statements based
on our audits.

We conducted our audits in accordance with auditing standards generally
accepted in the United States.  Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining,
on a test basis, evidence supporting the amounts and disclosures in the
financial statements.  An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation.  We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan at
December 31, 2002 and 2001, and the changes in its net assets available for
benefits for the year then ended, in conformity with accounting principles
generally accepted in the United States.

Our audits were performed for the purpose of forming an opinion on the
financial statements taken as a whole. The accompanying supplemental schedule
of assets (held at end of year) as of December 31, 2002, is presented for
purposes of additional analysis and is not a required part of the financial
statements but is supplementary information required by the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. The supplemental schedule is the
responsibility of the Plan's management. The supplemental schedule has been
subjected to the auditing procedures applied in our audit of the financial
statements and, in our opinion, is fairly stated in all material respects in
relation to the financial statements taken as a whole.

			  Notes To Financial Statements
				December 31, 2002

1.  Accounting Policies:
    -------------------

    The accompanying financial statements have been prepared on the accrual
    basis of accounting.

    A.  Investment securities are stated at fair value.  Shares of mutual
	funds are valued at quoted market prices, which represent the net
	asset values of shares held by the Ohio Casualty Insurance Company
	Employee Savings Plan (the Plan) at year-end.

	Securities traded on a national securities exchange, including Ohio
	Casualty Corporation common stock, are valued at the last recorded
	sales price of the last business day of the plan year.

	The fair value of the participation units owned by the Plan in common
	trust funds, are valued by the Trustees best efforts to maintain a
	stable net asset value of $1.00.  Investments in the Managed Income
	Portfolio II Fund are valued at their estimated fair values, as
	determined in good faith by the Trustee.

    B.  Interest income is recorded as earned.  Dividend income is recorded
	on the ex-dividend date.

    C.  Purchases and sales of securities are recorded on a trade-date basis.

    D.  The Plan presents in the statement of changes in net assets available
	for benefits the net appreciation (depreciation) in the fair value of
	its investments which consists of the realized gains or losses and
	the unrealized appreciation (depreciation) on those investments.

    E.  Contributions from participants and the Company are recorded in the
	month the Company makes payroll deductions from Plan participants.
	Participant contributions are accrued, if applicable, for the last
	pay period of the Plan year.

    F.  Benefits are recorded by the Trustee when paid.

    G.  The preparation of financial statements in conformity with accounting
	principles generally accepted in the United States requires
	management to make significant estimates and assumptions that affect
	the amounts reported in the financial statements and accompanying
	notes.  Actual results could differ from those estimates.

2.  Description of Plan:
    -------------------

    The following brief description of the Plan is provided for general
    information purposes only.  Reference should be made to the Plan Document
    and The Ohio Casualty Insurance Company Benefits Manual for a complete
    description of the Plan.

    A.  General:
	The Plan, which is subject to provisions of the Employee Retirement
	Income Security Act of 1974 (ERISA), is a defined contribution plan
	covering all employees of the Company who have elected to participate.

    B.  Participants of the Plan must be at least 18 years of age and be a
	full-time or part-time employee working 20 hours or more per week to
	be eligible.

    C.  Participants direct the investment of their contributions into the
	fund options available. Participants may contribute between 1-32% of
	eligible compensation to the Plan on a before and/or after-tax basis.
	From January 1 through June 30, 2002, the Company matched 50% of the
	first 6% of eligible compensation contributed to the Plan and all of
	the employer contributions were directed to the Ohio Casualty Stock
	Fund.  Effective July 1, 2002, employer contributions are invested
	according to the participant's investment direction. The Ohio
	Casualty Stock Fund is an Employee Stock Ownership Plan (ESOP).
	Eligible Plan participants can diversify a portion of these
	contributions after meeting the Plan's eligibility requirements (age
	55 and 10 years of Plan participation).  Effective July 1, 2002,
	participants can diversify up to 25% of the employer contributions
	and investment earnings in the Ohio Casualty Stock Fund once per
	calendar quarter. In addition, participants are 100% vested in the
	value of their contributions and their investment earnings, as well
	as 100% vested in the value of the Company contributions and their
	investment earnings.

    D.  Each participant's account is credited with his/her contributions,
	his/her share of the Company's contributions and an allocation of
	fund earnings.  Allocations of fund earnings are based on
	participant's account balances, as defined by the Plan.  The
	participant is entitled to his/her fully vested account balance.

    E.  Certain costs of administering the Plan are paid by the Company.
	These costs totaled $74,158 and $70,464 for the years ended December
	31, 2002 and 2001.

    F.  Benefits are payable to participants upon termination of employment,
	retirement, disability retirement, and/or death. In-service
	withdrawals, including withdrawals due to financial hardship as
	defined by the Internal Revenue Service, are also available.

    G.  Effective January 1, 2001, Fidelity Investments became the
	recordkeeper and trustee for the Employee Savings Plan.  All of the
	investment options, with the exception of the Interest Income Fund and
	the Ohio Casualty Stock Fund, were sold and reinvested on January 2,
	2001 in comparable funds offered by Fidelity Investments.  The T. Rowe
	Price Small Cap Core Equity Fund Plan assets were transferred to
	the T. Rowe Price Small Cap Value Fund; the Vanguard Institutional
	Index Fund Plan assets were transferred to the Fidelity US Equity
	Index Pool Fund; ICAP FDS Equity Fund Plan assets were transferred to
	the Fidelity Equity Income Fund;

		      Notes To Financial Statements, Continued
			       December 31, 2002

2.  Description of Plan, Continued:
    ------------------------------

    Vanguard Balanced Index Fund Plan assets were transferred to the Fidelity
    Balanced Fund; and CT&T FDS Montag & Caldwell Growth Fund Plan assets
    were transferred to the Fidelity Blue Chip Fund.

3.  Plan Termination:
    ----------------

    Although it has not expressed any intention to do so, the Company has the
    right under the Plan to discontinue its contributions at any time and to
    terminate the Plan subject to the provisions set forth in ERISA.

    In the event of Plan termination, the Plan's assets will be used to
    provide benefits for participants and beneficiaries in accordance with
    federal law.

4.  Tax Status:
    ----------

    The Plan has received a determination letter from the Internal Revenue
    Service dated February 4, 2003, stating that the Plan is qualified under
    Section 401(a) of the Internal Revenue Code (the Code) and, therefore,
    the related trust is exempt from taxation. However, subsequent to the
    issuance of the favorable determination letter, the Plan was amended.
    Once qualified, the Plan, as amended, is required to operate in
    conformity with the Code to maintain its qualification.  The Plan
    Administrator believes the Plan, as amended, is being operated in
    compliance with the applicable requirements of the Code and, therefore,
    believes that the Plan is qualified and the related trust is tax exempt.

5.  Investments:
    -----------

    The following investments represent 5% or more of the Plan's net assets:

7.  Loans Receivable - Participants:
    -------------------------------

    Participants are permitted to borrow from the trust using their vested
    account balance as collateral.  The minimum loan amount is $1,000 and the
    maximum loan amount is the lesser of $50,000 reduced by the participant's
    highest outstanding aggregate balance of loans from the Plan during the
    previous twelve (12) months, the total value of the participant's before-
    tax, after-tax, and rollover accounts, or 50% of the vested value of the
    participant's accounts.  Interest is charged at Chase Manhattan Bank's
    prime commercial rate plus 1%.  Repayment of loans are arranged through
    payroll deductions which range from five years to fifteen years for a
    home loan.  At December 31, 2002 there were 611 individual loans
    outstanding, maturing between January 2003 through September 2017, with
    interest rates ranging from 5.25% to 10.0%. The outstanding participant
    loan balance was $3,023,768 and $2,829,072 for December 31, 2002 and
    2001, respectively.
