ITEM 5.  Other Events and Regulation FD Disclosure
- -------  -----------------------------------------

On March 19, 2002, Ohio Casualty Corporation (the "Company") issued and sold,
in a private placement, $201,250,000 aggregate principal amount of 5.00%
Convertible Notes (the "Notes") due 2022.  The Notes are convertible, subject
to certain conditions, into common stock at an initial conversion rate of
44.2112 common shares per $1,000 principal amount of the Notes, which is
equivalent to an initial conversion price of approximately $22.62 per share.

 The Notes were sold to Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner &
Smith Incorporated, Salomon Smith Barney Inc. and McDonald Investments Inc. as
"accredited investors" within the meaning of Rule 501 under the Securities Act
of 1933, (the "Act"), in reliance upon the private placement exemption
afforded by Section 4(2) of that Act, and were offered and sold to "qualified
institutional buyers" under Rule 144A of the Securities Act.   Pursuant to a
registration rights agreement entered into in connection with the private
offering, the Company has agreed to file a registration statement under the
Act to permit registered resales of the Notes and the common stock issuable
upon conversion of the Notes.

The aggregate offering price of the Notes was $201,250,000, 100% of the
principal amount thereof.  The purchase price paid to the Company by the
initial purchasers was the initial offering price less a discount of
$6,707,662, 3.333% of the principal amount of the Notes.  The net proceeds
from the sale of the Notes were used to repay borrowings under the Company's
revolving credit facility.

A copy of the Indenture for the convertible Notes offering is attached hereto
as Exhibit 4 and is incorporated herein by reference.

The information included in this report regarding the granting of registration
rights to purchasers of the Notes shall not constitute an offer to sell or the
solicitation of an offer to buy such Notes, nor shall there be any sale of the
Notes in any state in which such offer, solicitation or sale would be unlawful
prior to registration or qualification under the securities law of such state.
