I, Donald F. McKee, certify that:

	     Ohio Casualty Corporation;

	2.   Based on my knowledge, this report does not contain any
	     untrue statement of a material fact or omit to state a
	     material fact necessary to make the statements made, in
	     light of the circumstances under which such statements
	     were made, not misleading with respect to the period
	     covered by this report;

	3.   Based on my knowledge, the financial statements, and
	     other financial information included in this report,
	     fairly present in all material respects the financial
	     condition, results of operations and cash flows of the
	     registrant as of, and for, the periods presented in
	     this report;

	4.   The registrant's other certifying officer(s) and I are
	     responsible for establishing and maintaining disclosure
	     controls and procedures (as defined in Exchange Act
	     Rules 13a-15(e) and 15d-15(e)) for the registrant and
	     have:

		   (a)  Designed such disclosure controls and
			procedures, or caused such disclosure
			controls and procedures to be designed under
			our supervision, to ensure that material
			information relating to the registrant,
			including its consolidated subsidiaries, is
			made known to us by others within those
			entities, particularly during the period in
			which this report is being prepared;

		   (b)  Evaluated the effectiveness of the
			registrant's disclosure controls and
			procedures and presented in this quarterly
			report our conclusions about the effectiveness
			of the disclosure controls and procedures, as
			of the end of the period covered by this report
			based on such evaluation; and

		   (c)  Disclosed in this report any change in
			the registrant's internal control over
			financial reporting that occurred during the
			registrant's most recent fiscal quarter (the
			registrant's fourth fiscal quarter in the
			case of an annual report) that has materially
			affected, or is reasonably likely to materially
			affect, the registrant's internal control over
			financial reporting; and

	5.   The registrant's other certifying officer(s) and I have
	     disclosed, based on our most recent evaluation, of
	     internal control over financial reporting, to the
	     registrant's auditors and the audit committee of the
	     registrant's board of directors (or persons performing
	     the equivalent functions):

		(a)   All significant deficiencies and material
		      weaknesses in the design or operation of internal
		      control over financial reporting which are
		      reasonably likely to adversely affect the
		      registrant's ability to record, process, summarize
		      and report financial information; and

		(b)   Any fraud, whether or not material, that involves
		      management or other employees who have a
		      significant role in the registrant's internal
		      control over financial reporting.
