                     THE OHIO CASUALTY INSURANCE COMPANY
                             EXCESS BENEFIT PLAN

	This Plan is intended to provide a means of equalizing the benefits
of those employees of The Ohio Casualty Insurance Company participating in
the Savings Plan (as defined herein), whose funded benefits under that Plan
are or will be limited by application of ERISA (as defined herein), the Code
(as defined herein) or any applicable law, rule or regulation.  This Plan is
intended to be an "excess benefit plan" as that term is defined in ERISA
Section 3(36) with respect to those participants whose benefits under the
Savings Plan have been or will be limited by Code Section 415 and a "top hat"
plan meeting the requirements of ERISA Sections 201(2), 301(a)(3), and
401(a)(1) with respect to those participants whose benefits under the Savings
Plan have been limited or will be limited by Code Section 401(a)(17).  This
Plan shall also consolidate the benefits accrued and unpaid under the Ohio
Casualty Insurance Company Supplemental Executive Savings Plan (the "Prior
Plan") as of December 31, 2004 and any benefits provided under this Plan
shall be in lieu of any benefits provided under that Prior Plan that remain
unpaid as of December 31, 2004. This Plan shall be unfunded for tax purposes
and for purposes of Title I of ERISA.  This Plan shall be effective as of
January 1, 2005.

	Year.

	the Savings Plan, except that such Base Pay shall be determined without
	regard to the limitations of Code Section 401(a)(17).  Notwithstanding
        the preceding sentence to the contrary, to the extent base pay deferred
	under a nonqualified deferred compensation plan is excluded from Base

	included in Base Pay for purposes of this Plan.

            (5) The term "Beneficiary" shall mean such person or legal entity
	as may be designated by a Participant in accordance with Section 6 or

		   (i)	After the Effective Date, an event that would be
	    required to be reported as a change in control for purposes of the
	    Exchange Act.

	 	  (ii)	During any 24-consecutive-calendar-month period ending

		the OCC Board;


                                     -2-





		provided, however, that any new director whose nomination for
		election by the Corporation's shareholders was approved, or
		who was appointed or elected to the OCC Board, by the vote of
		two-thirds of the directors then still in office who were in
		office at the beginning of the 24-consecutive-calendar-month
		period will be disregarded in determining if there has been a
		change in the majority of the OCC Board.

		  (iii)	During any 12-consecutive-calendar month period
		beginning after the Effective Date, any entity or "person,"
		including a "group" as contemplated by Exchange Act Sections

		(as defined in Rule 13d-3 under the Exchange Act) through a
		tender offer or otherwise, of Common Shares representing more
		than 20 percent or more of the combined voting power of the
		Corporation's then outstanding Common Shares.  However, this
		element of this definition will be applied without regard to
		the effect of any redemption of Common Shares by the
		Corporation or the acquisition of Common Shares by the Company
		or any Affiliate and, solely for purposes of applying this
		subsection 1.1(7)(a)(iii), after ignoring any Common Shares
		acquired:

			A. By the Company or any employee benefit plan
                   maintained by the Company or any Affiliate;

			B. Directly, through an equity compensation plan
		   maintained by the Company or any Affiliate;

			C. Directly, through inheritance, gift, bequest or by
		   operation of law on the death of an individual; or

			D. By any entity or "person," including a "group" as
		   contemplated by Exchange Act Sections 13(d)(3) and 14(d)(2),
		   with respect to which that acquirer has filed SEC Schedule
		   13G indicating that the Common Shares were not acquired and
		   are not held for the purpose of or with the effect of
		   changing or influencing, directly or indirectly, the
		   Corporation's management or policies, unless and until that
		   entity or person indicates that its intent has changed by
		   filing SEC Schedule 13D.

		  (iv)	After the Effective Date, any entity or "person,"
		including a "group" as contemplated by Exchange Act Sections
		13(d)(3) and 14(d)(2) and, in the aggregate, all employee
		pension benefit plans, as defined in Section 3(3) of ERISA,

		voting power of the Corporation's then outstanding Common
		Shares.

		   (v)	After the Effective Date, the Corporation's
		shareholders approve a definitive agreement to merge or combine
		the Corporation with or into another entity, a majority of the
		directors of which were not

                                   -3-





		members of the OCC Board immediately before the merger and
		in which the Corporation's shareholders will hold less than 50
		percent of the voting power of the surviving entity.  When
		applying this element of this definition, shareholders will be
		determined immediately before and immediately after the merger
		or combination.

		  (vi)	Within any 12-consecutive-calendar-month period ending
		after the Effective Date, any entity or "person," including a
		"group" as contemplated by Exchange Act Sections 13(d)(3) and
		14(d)(2) and Code Section 280G, acquires, either directly or as
		a "beneficial owner" (as defined in Rule 13d-3 under the
		Exchange Act) of another entity or person, assets of the
		Corporation, Company and all Affiliates (the "Group") having a
		total gross fair market value equal to or greater than 50
		percent of the book value of the Group's assets. For purposes of
		this definition, "book value" will be established on the basis
		of the latest consolidated financial statement the Corporation
		filed with the Securities and Exchange Commission before the
		date any 12-consecutive-calendar-month measurement period began.
		However, except as otherwise provided in this section, this
		element of this definition will be applied after ignoring:

			A. Any transfer of assets to an entity, more than 50
                   percent of the total value or voting power of which is owned
                   by the Company and/or one or more members of the Group; or

		  13d-3 under the Exchange Act), more than 50 percent of the
		  total value or voting power of the Corporation's outstanding
		  securities.

		b.  For purposes of applying all parts of this definition,

	will be disregarded, (ii) any transfer of assets to an Employee or to
	(or merger of the Corporation with) any other entity or "person"
	(including a "group" as contemplated by Exchange Act Sections 13(d)(3)
	and 14(d)(2)) acting in concert with the Employee will be disregarded

				SECTION 2

		PARTICIPATION BY SELECTED EMPLOYEES
		-----------------------------------

	2.1	Participation.  (a)  Participation in the Plan is
limited to each Employee who meets any of the following conditions:

          (i)	He or she is an Eligible Employee who was a participant
	in the Prior Plan as of December 31, 2004 and had not received
	the entire amount of his or her benefit under the Prior Plan as
	of December 31, 2004 (a "Prior Plan Participant");

          (ii)	He or she is an Eligible Employee whose Short Period
	Excess Benefit (as determined under Section 3.1) is greater
	than zero; or

          (iii)	He or she is an Eligible Employee whose Projected
	Excess Benefit for any Plan Year is greater than zero.

      (b) Each Eligible Employee who meets the requirements of clause
(a)(i) or (a)(ii) shall become a Selected Employee and a Participant
as of January 1, 2005.  Each Eligible Employee who meets the requirement
of clause (a)(iii) shall become a Selected Employee and a Participant as
of the first day the Plan Year for which he or she meets the requirements
of clause (a)(iii) or, if later, his or her first day of employment
during such Plan Year.  In no event shall any Employee become a
Participant earlier than January 1, 2005.

	2.2	Cessation of Active Participation.  A Participant
who suffers a Termination of Employment, Retires or dies shall
immediately thereupon cease active participation in the Plan.

faith that a Participant is not a member of a select group of management
or highly compensated employees, as membership in such group is
determined in accordance with ERISA Sections 201(2), 301(a)(3) and
401(a)(1), the Committee may, in its sole discretion, terminate such

                                 SECTION 3

			ANNUAL EXCESS BENEFIT CREDITS
			-----------------------------

	3.1	Amount of Credit.  (a) For each Plan Year beginning on
or after January 1, 2005, on or before the due date for the Company to
file its federal income tax return (including extensions) for the calendar
year in which such Plan Year ended, each Participant who was an Eligible
Employee during that Plan Year shall receive an Excess Benefit Credit for
that Plan Year equal to the amount provided under Section 3.1(b).

          (b)	For the 2005 Plan Year, a Participant's Excess Benefit
Credit for such Plan Year shall equal the sum of (i) his or her Deemed
Excess Benefit for the 2005 Plan Year and (ii) his or her Short Period
Excess Benefit.  For Plan Years beginning on or after January 1, 2006,
a Participant's Excess Benefit Credit for such Plan Year shall equal the
sum of (i) his or her Deemed Excess Benefit for such Plan Year and
(ii) his or her Adjusted Excess Benefit for such Plan Year.

          (c)	A Participant's Short Period Excess Benefit shall equal:

            (i)	the amount, if any, by which his or her Uncapped Savings
	Contributions for the entire 2004 calendar year exceed his or her
	Savings Plan Contributions for the entire 2004 calendar year,
	determined as if the Plan were in effect for that entire year and
	reduced by amounts described in clauses (ii) and (iii);

            (ii) the amount determined under clause (i) above not
	attributable to the Short Period; and

           (iii) any amount credited under The Ohio Casualty Insurance
	Company Executive Supplemental Savings Plan for the Short Period.

	3.2	Adjustment to Excess Benefit Account.  A Participant's
Adjusted Excess Benefit for any Plan Year shall equal his or her
Theoretical Excess Benefit for the preceding Plan Year minus his or her
Deemed Excess Benefit for such preceding Plan Year.  For the 2005 Plan
Year, each Participant's Adjusted Excess Benefit shall be zero.  A
Participant's Adjusted Excess Benefit for a Plan Year shall be credited
to his or her Excess Benefit Account as soon as administratively feasible
after such Adjusted Excess Benefit for such Plan Year is determined but
not before the beginning of such Plan Year; however, in no event shall
a Participant receive an Adjusted Excess Benefit that is greater than
zero for a Plan Year unless such Participant was an active Employee at
some time during such Plan Year.


                                  -13-




				SECTION 4

				ACCOUNTS
				--------

	4.1	Establishment of Excess Benefit Accounts.  For purposes
of the Plan, the Committee shall cause a separate Excess Benefit Account
to be established in the name of each Participant.  Within each
Participant's Excess Benefit Account, the Committee shall separately
account for such Participant's Code Section 415 Excess Benefit and such
Participant's Top Hat Excess Benefit.  Each Prior Plan Participant shall
receive a credit to such Participants' Excess Benefit Account at the
beginning of January 1, 2005 equal to the amounts credited to such
Participant's account under the Prior Plan on December 31, 2004 and such
amounts shall thereafter be adjusted in accordance with Section 4.2 and
administered in accordance with the terms of this Plan.  The Excess
Benefit Credits of a Participant shall be credited to such Participant's
Excess Benefit Account as of the date such Excess Benefit Credits are
determined to be credited by the Committee.  All amounts credited to a
Participant's Excess Benefit Account shall be adjusted in the manner
determined under Section 4.2.

	4.2	Crediting/Debiting of Account.  In accordance with, and
subject to, the rules and procedures that are established from time to
time by the Committee, in its sole discretion, a Participant's Excess
Benefit Account Balance shall be adjusted in accordance with the
following rules:

          (a)	Election of Measurement Funds.  Each Selected Employee
or Prior Plan Participant shall elect on such election form designated
by the Committee (or its designee) for such purpose the Measurement
Fund(s) that will be used to determine the adjustment amounts to be
credited to or debited from his Excess Benefit Account for the
applicable Plan Year or portion thereof in which the Selected Employee
or Prior Plan Participant commences participation in the Plan and
continuing thereafter for each subsequent Plan Year in which such
Selected Employee or Participant participates in the Plan, unless
changed in accordance with the next sentence.  Commencing with the
first calendar quarter beginning after a Participant's commencement
of participation in the Plan and continuing once per quarter thereafter
for each calendar quarter in which the Participant participates in the
Plan, as of any Valuation Date in the applicable quarter, the
Participant may (but is not required to) elect, by submitting such
election on a form designated by the Committee (or its designee) for
such purpose to the Committee (or its designee) that is accepted and
approved by the Committee (or its designee) or in such other manner
required by the Committee (or its designee), to change the Measurement
Fund(s) to be used to determine the adjustment amounts to be credited
to or debited from such Participant's Excess Benefit Account.  If an
election is made in accordance with the previous sentence, it shall
apply as of the first Valuation Date immediately following the


				-14-





date of receipt and approval by the Committee (or its designee) and
shall continue thereafter for each subsequent calendar quarter in
which the Participant participates in the Plan, unless changed in
accordance with the previous sentence.

          (b)	Proportionate Allocation.  Any election under
Section 4.2(a) above shall result in 100% of a Participant's Excess
Benefit Account Balance being allocated among the Measurement Fund(s)
elected by the Participant as if the Participant was making an actual
investment in the Measurement Fund(s) equal to the portion of such
Participant's Excess Benefit Account Balance allocated to such
Measurement Fund(s).

          (c)	Measurement Funds.  A Participant must elect at least
one of the Measurement Funds described in Appendix B for the purpose
of determining the manner in which such Participant's Excess Benefit
Account Balance is to be adjusted.  If a Participant fails to elect
a Measurement Fund, the Committee shall select a default Measurement
Fund for the purpose of determining the manner in which such
Participant's Excess Benefit Account Balance is to be adjusted. The
Measurement Funds established by the Committee (or its designee) and
described in Appendix B may not include a Company Stock fund, which
would be invested in Shares, but shall include mutual funds selected
and approved by the Committee (or its designee) and a money market
fund selected and approved by the Committee (or its designee). The
Committee (or its designee) shall duly consider, but is not required
to approve, the Participant's requested election of the Measurement
Fund or Funds or the Participant's requested change in the
Measurement Fund or Funds.  In all events, the Participant's Excess
Benefit Account Balance shall be determined by reference to such
Measurement Fund(s) as the Committee (or its designee) shall have
selected from time to time with respect to the Participant's Excess
Benefit Account Balance.  As necessary, the Committee (or its
designee) may, in its sole discretion, discontinue, substitute or
add a Measurement Fund(s).  Each such action will take effect as of
the first day of the earliest Valuation Date that follows by at
least 30 days the day on which the Committee (or its designee) gives
Participants advance written notice of such change unless the Committee
(or its designee) determines circumstances warrant a shorter advance
notice period.

          (d)	Crediting or Debiting Method.  The performance of the
elected Measurement Fund(s) (either positive or negative) will be
determined by the Committee (or its designee), in its sole discretion,
based on the performance of the Measurement Fund(s) itself (taking
into account the reinvestment of dividends, capital gains and interest
income distributions therefrom).  A Participant's Excess Benefit
Account Balance shall be debited or credited as of the end of each
Valuation Date, based on the performance of the applicable Measurement
Fund(s) (at the closing price on such Valuation Date) selected by the
Participant, as determined by the Committee (or its designee) in its
sole discretion, as though (i) the Participant's Excess Benefit Account
Balance was invested in the Measurement Fund(s) in the manner selected
by the Participant and in effect as of the end of each such Valuation
Date (at the closing price on such Valuation Date); (ii) any Excess
Benefit Credits credited to the Participant?s Excess Benefit Account
on that Valuation Date were invested in the Measurement Fund(s) (at
the closing price on such Valuation Date) selected by the Participant
and in effect as of the end of that Valuation Date; and (iii) any
distribution made to a Participant that decreases such Participant's
Excess Benefit Account Balance ceased to be invested in the applicable
Measurement


                                 -15-






Fund(s) (at the closing price on such Valuation Date) as of the
Valuation Date immediately preceding the date as of which such
distribution occurred.

          (e)	No Actual Investments.  Notwithstanding any other
provision of this Plan that may be interpreted to the contrary, the
Measurement Funds are to be used for measurement purposes only, and
a Participant's election or deemed election of any such Measurement
Fund(s), the allocation of his or her Excess Benefit Account Balance
thereto, the calculation of adjustment amounts and the crediting or
debiting of such amounts to a Participant's Excess Benefit Account
Balance shall not be considered or construed in any manner as an
actual investment of such Participant's Excess Benefit Account
Balance in any such Measurement Fund.  If the Company decides to
invest funds in any or all of the Measurement Funds, no Participant
shall have any rights in or to such investments themselves.  Without
limiting the foregoing, a Participant's Excess Benefit Account
Balance shall at all times be a bookkeeping entry only and shall not
represent any investment made on such Participant?s behalf by the
Company.  The Participants shall, at all times, remain unsecured
creditors of the Company.


                                 -16-





				SECTION 5

			      DISTRIBUTIONS
			      -------------

	5.1	In General.  Except as otherwise provided in this
Section 5, the Excess Benefit Account Balance of a Participant shall
be payable to such Participant (or, in the case of the death of a
Participant, his or her Beneficiary) in the manner determined under
Section 5.4.

	5.2	Distributions to Incompetents.  If the Committee
(or its designee) determines, in its discretion, that a payment under
the Plan is to be made to a minor, a person declared incompetent or
to a person incapable of handling his or her property, the Committee
(or its designee) may direct such payment to the guardian, legal
representative or person having the care and custody of such minor,
incompetent or incapable person.  The Committee (or its designee) may
require proof of minority, incompetence, incapacity or guardianship,
as it may deem appropriate prior to making such payment.  Any such
payment shall be a payment for the account of the Participant and a
Beneficiary, as the case may be, and shall be a complete discharge
of any liability under the Plan for such payment amount.

	5.3	Court Ordered Distributions.  The Committee (or its
designee) is authorized to make any payments required by a domestic
relations order (as defined in Code Section 414(p)(1)(B)) to an
individual other than the Participant whose Excess Benefit Account
is the subject of such order at the time and in the manner necessary
to fulfill such order.

	5.4	Method of Payment.  Distributions of a Participant's
Excess Benefit Account Balance shall be made in cash and in either a
lump sum or five annual installments, as elected by such Participant
in the manner described below.

          (a)	Subject to the requirements of Section 5.4(b), if a
	Participant suffers a Termination of Employment or Retires,
	payment of such Participant's Excess Benefit Account Balance
	shall be made to such Participant as of his or her Benefit
	Commencement Date in accordance with the payment method in
	effect at the time of such distribution, as determined under
	this Section 5.4(a).  A Participant may elect (a
	"distribution election") to receive his or her Excess
	Benefit Account Balance in a lump sum or five annual
	installments, provided that such distribution election is
	made by the later of the following dates:  (i) December 31,
	2005 or if earlier, before his or her termination of
	employment; or (ii) the December 31 preceding the Plan Year
	in which he or she first became eligible to participate in
	the Plan, or if later, the date that is no later than 30
	days after the date as of which he or she first became
	eligible to participate in the Plan but only if he has
	never participated in any other plan required to be
	aggregated with this Plan with respect to such Participant
	under Code Section 409A and the applicable provisions of
	the regulations and administrative guidance issued
	thereunder.  To the


                                 -17-





	extent a Participant has elected to receive his or her
	Excess Benefit Account Balance in the form of annual
	installments, each annual installment after the first
	annual installment shall be paid as of the applicable
	anniversary of his or her Benefit Commencement Date.  If at
	the time of a Participant's Retirement or Termination of
	Employment the Committee (or its designee) determines that
	no such distribution election is in effect (or such
	distribution election was not timely made) with respect to
	such Participant's Excess Benefit Account at that time,
	such Participant's Excess Benefit Account Balance shall be
	distributed in a lump sum.

          (b)	If a Participant dies before payment of all amounts
	payable under the Plan with respect to him or her has been
	made, the remaining amount of such Participant's Excess
	Benefit Account Balance shall be distributed to such
	Participant's Beneficiary in a single lump sum as of the
	first Valuation Date following the Committee's (or its
	designee's) receipt of sufficient notice of such
	Participant's death.

	5.5	Distribution to Pay Taxes.  To the extent permitted under
Code Section 409A and/or the administrative guidance and regulations
issued thereunder, the Committee (or its designee) may distribute the
portion of a Participant's Excess Benefit Account Balance necessary to pay
(i) the Federal Insurance Contributions ("FICA") tax imposed under Code
Section 3101, 3121(a) and 3121(v)(2), where applicable, on amounts deferred
under this Plan (the "FICA Amount"), (ii) the income tax at source on wages
imposed under Code Section 3401 or the corresponding withholding provisions
of applicable state, local or foreign tax laws as a result of the payment
of the FICA Amount and (iii) the additional income tax at source on wages
attributable to the pyramiding Code Section 3401 wages and taxes.  However,
the total payment under this Section 5.5 may not exceed the aggregate of
the FICA Amount and the income tax withholding related to such FICA Amount.
Any amount distributed under this Section 5.5 shall be used solely to pay
the FICA Amount and the income tax withholding related to such FICA Amount.

	5.6	Distribution for Code Section 409A Violation.  If the Plan
fails to meet the requirements of Code Section 409A with respect to a
Participant, the Committee (or its designee) may distribute such Participant's
Excess Benefit Account Balance as soon as administratively feasible following
discovery of such failure, but only to the extent of the amount required to be
included in such Participant's gross income as a result of the failure to
comply with the requirements of Code Section 409A and the regulations issued
thereunder.

	5.7	Distribution Upon Plan Termination.  Upon the termination of
this Plan, the Committee (or its designee) may distribute a Participant's
Excess Benefit Account Balance as


                                 -18-





soon as administratively feasible following such termination, provided that
one of the following conditions is satisfied:

          (a)	Such Plan termination occurs, at the Committee's (or its
	designee's) discretion, within twelve months of a corporate
	dissolution of the Employer taxed under Code Section 331 or with the
	approval of a bankruptcy court under Title 11 U.S.C. Section 503
	(b)(1)(A), provided that each Participant's Excess Benefit Account
	Balance is included in the applicable Participant's gross income in
	the latest of:

       		(1) The calendar year in which the Plan terminates;

		(2) The calendar year in which such Excess Benefit Account
	Balance is no longer subject to a substantial risk of forfeiture; or

		(3) The first calendar year in which such distribution is
	administratively practicable;

          (b)	Such Plan termination occurs, at the Committee's (or its
	designee's) discretion, within the thirty (30) days preceding or the
	twelve (12) months following a Change in Control.  For purposes of
	this Section 5.7, the Plan will be treated as terminated only if all
	substantially similar plans or arrangements sponsored by the Employer
	are terminated so that each Participant in the Plan and all
	participants under substantially similar plans or arrangements are
	required to receive all amounts of compensation deferred under this
	Plan and the other terminated plans or arrangements within twelve
	(12) months of the date of termination of the Plan and other
	substantially similar plans or arrangements;

          (c)	Such Plan termination occurs, at the Employer's discretion,
	at any time, provided that, with respect to a Participant in the
	Plan:

		(1) All plans or arrangements sponsored by the Employer that
	would be aggregated with the Plan under Code Section 409A and the
	applicable provisions of the regulations and administrative guidance
	issued thereunder if such Participant participated in all of such
	plans or arrangements (the "Aggregated Participant Plans") are
	terminated.


                                 -19-





		(2) No payments other than payments that would be payable
	under the terms of that Participant's Aggregated Participant Plans
	if the Plan termination had not occurred are made within twelve (12)
	months of the termination of the Participant's Aggregated Participant
	Plans;

		(3) All payments are made within twenty-four (24) months of
	the termination of such Participant's Aggregated Participant Plans;
	and

		(4) The Employer does not adopt at any time within five (5)
	years following the date of termination of the Plan a new arrangement
	that would become a part of that Participant's Aggregated Participant
	Plans if that Participant participated both in such new arrangement
	and the Plan.

	5.8	Timing of Actual Distributions.  Any distribution or payment
of any portion of a Participant's Excess Benefit Account Balance shall be
treated as made as of the date designated under the applicable provisions of
this Section 5 only if (a) such distribution or payment does not occur before
such date and (b) such distribution or payment actually occurs by the
applicable deadline permitted for such distribution or payment under Code
Section 409A and the regulations and administrative guidance issued
thereunder.

	5.9	Limitations on Distribution.  Except as otherwise provided in
this Section 5, no distribution of any portion of a Participant's Excess
Benefit Account Balance (and no acceleration of the time or schedule of any
payment or amount scheduled to be paid pursuant to a payment under the Plan)
shall be permitted under the Plan.

	5.10	Valuation of Distributions.  All distributions under the Plan
shall be based upon a Participant's Excess Benefit Account Balance as of the
end of the Valuation Date immediately preceding the date of distribution.

	5.11	Right to Withhold and Receive Payment for Taxes.  To the
extent required by law in effect at the time a distribution is made from the
Plan, the Company or its agents shall have the right to withhold or deduct
from any distributions or payments any taxes required to be withheld by
federal, state or local governments.  In addition, the Company shall withhold
from a Participant's nondeferred compensation, any applicable payroll and/or
income taxes that may be due at the time any Excess Benefit Credit was made
under the Plan.  If a Participant's nondeferred compensation is insufficient
for the Company to withhold any applicable payroll


				-20-





and/or income taxes that may be due at the time any Excess Benefit Credit was
made under the Plan, the Company or Committee (or its designee) may require
such Participant to pay such taxes to the Company in the manner determined by
the Committee (or its designee).  If a Participant is required to pay any
applicable payroll and/or income taxes under the preceding sentence and such
Participant fails to pay such taxes by the deadline provided by the Company
or Committee (or its designee), the Committee (or its designee) may
irrevocably forfeit such Participant's Excess Benefit Account Balance.  Any
amounts forfeited under the preceding sentence shall not be paid to such
Participant or his or her Beneficiary.


				-21-





				SECTION 6

			      BENEFICIARIES
			      -------------

	6.1	Beneficiary Designation.  Each Participant from time to time
may designate any person or persons (who may be named contingently or
successively) to receive such benefits as may be payable under the Plan upon
or after the death of a Participant, and such designation may be changed from
time to time by the Participant by filing a new designation.  Each
designation shall revoke all prior designations by such Participant, shall be
in a form prescribed by the Committee (or its designee), and shall be
effective only when approved by the Committee (or its designee) during the
Participant's lifetime.

	6.2	No Beneficiary Designation.  In the absence of a valid
Beneficiary designation, or if, at the time any Plan payment is due to a
Beneficiary, there is no living Beneficiary validly named by the Participant,
the Committee (or its designee) shall pay any such Plan payment to the
Participant's spouse, or, if none, to the Participant's child or children, or,
if none, to the Participant's parent(s), or, if none, to the Participant's
estate.  In determining the existence or identity of anyone entitled to
receive a Plan payment as aforesaid, or if a dispute arises with respect to
any such payment, then, notwithstanding the foregoing, the Committee (or its
designee) in its sole discretion, may distribute such payment to the estate
of the Participant without liability for any taxes or other consequences
that might flow therefrom, or may take such other action as the Committee
(or its designee) deems to be appropriate, provided that such action is not
inconsistent with the requirements of Code Section 409A and the regulations
and administrative guidance issued thereunder.

				SECTION 7

		   FUNDING AND PARTICIPANT'S INTEREST
		   ----------------------------------

	7.1	Plan Unfunded.  The Plan shall be unfunded and no trust or
special deposit shall be created, or deemed to be created, by the Plan or the
Company.  The crediting of amounts to the Excess Benefit Account of a
Participant shall be made through recordkeeping entries.  No actual funds
shall be segregated, reserved, or otherwise set aside; provided, however,
that nothing herein shall prevent the Company from establishing one or more
grantor trusts from which distributions due under the Plan may be paid.
All distributions shall be paid by the Company from its general assets and/or
from one or more grantor trusts established by the Company and a Participant
or a Beneficiary shall have the rights of a general, unsecured creditor
against the Company for any distributions due hereunder.  The benefits
provided to Participants under the Plan constitute a mere promise by the
Company to make such payments in the future.

	7.2	Interests of Participants Under the Plan.  Each Participant
has an interest only in the cash value of his Excess Benefit Account.  No
Participant shall have any right or interest in any specific fund, stock or
securities.


				-23-





				SECTION 8

		   ADMINISTRATION AND INTERPRETATION
		   ---------------------------------

	8.1	Administration.  The Plan shall be administered by the
Committee, which may delegate all or a portion of its duties to one or more
employees of the Company.  The Committee has, to the extent appropriate and
in addition to the powers described elsewhere in the Plan, full
discretionary authority to construe and interpret the terms and provision of
the Plan; to make factual determinations concerning a Participant's
eligibility for benefits under the Plan and other administrative matters
relating to a Participant's Excess Benefit Account; to adopt, alter and
repeal administrative rules, guidelines and practices governing the Plan; to
perform all acts, including the delegation of its administrative
responsibilities to advisors or other persons who may or may not be
employees of the Company; and to rely upon the information or opinions of
legal counsel or experts selected to render advice with respect to the Plan,
as it shall deem advisable, with respect to the administration of the Plan.
Any action to be taken by the Committee shall be taken by a majority of its
members, either at a meeting or by written instrument approved by such
majority in the absence of a meeting.  A written resolution or memorandum
signed by one Committee member and the secretary of the Committee shall be
sufficient evidence to any person of any action taken pursuant to the Plan.

	8.2	Interpretation.  The Committee (or its designee) may take any
action, correct any defect, supply any omission or reconcile any
inconsistency in the Plan, or in any election hereunder, in the manner and to
the extent it shall deem necessary to carry the Plan into effect or to carry
out the Board's purposes in adopting the Plan.  Any decision, interpretation
or other action made or taken by the Committee (or its designee) arising out
of or in connection with the Plan, shall be within the absolute discretion of
the Committee (or its designee), and shall be final, binding and conclusive
on the Company as well as all Participants, Beneficiaries and their
respective heirs, executors, administrators, successors and assigns.  The
determinations by the Committee (or its designee) with respect to the Plan
need not be uniform, and may be made selectively among Employees, whether or
not they are similarly situated.

	8.3	Records and Reports.  The Committee (or its designee) shall
keep a record of proceedings and actions and shall maintain or cause to be
maintained all such books of account, records, and other data as shall be
necessary for the proper administration of the Plan.  Such


				-24-





records shall contain all relevant data pertaining to individual Participants
and their rights under the Plan.

	8.4	Payment of Expenses.  The Company shall bear all expenses
incurred by it and by the Committee in administering the Plan.

	8.5	Indemnification for Liability.  The Company shall indemnify
the Committee, and the employees of the Company to whom the Committee
delegates duties under the Plan against any and all claims, losses, damages,
expenses and liabilities arising from their responsibilities in connection
with the Plan.

	8.6	Claims Procedure.  A Participant or Beneficiary who believes
he or she is entitled to a benefit under the Plan shall file a written claim
with the Committee.  If such claim is denied in whole or in part, the
Committee (or its designee) shall notify (in writing or electronically) such
Participant or Beneficiary (hereinafter referred to as the "Claimant") or an
authorized representative of the Claimant, as applicable, of any adverse
benefit determination (within the meaning of DOL Reg. Section 2560.503-1
(m)(4)) concerning such claim within ninety (90) days (forty-five (45) days
for disability benefit claims) of receipt of the claim.  If the Committee
(or its designee) determines that special circumstances require an extension
of time for processing the claim, the Committee (or its designee) shall notify
the Claimant in writing of the extension before the end of the initial ninety
(90)-day period (forty-five (45)-day period for disability benefit claims)
and the written notice shall indicate the special circumstances requiring an
extension of time and the date by which the Committee (or its designee)
expects to make a decision.  The extension of time shall not exceed ninety
(90) days (thirty (30) days for disability benefit claims) from the end of
the initial ninety (90)-day period (forty-five (45)-day period for
disability benefit claims).

	If the claim is a disability benefit claim and before the end of the
initial thirty (30)-day extension period the Committee (or its designee)
determines that due to matters beyond its control a decision cannot be
rendered within the extension period, the Committee (or its designee) may
extend the time for processing a Claimant's claim for an additional thirty
(30) days provided that the Committee (or its designee) informs the Claimant
in writing before the expiration of the first thirty (30)-day extension period
of the circumstances requiring the extension and the date as of which the
Committee (or its designee) expects to render a decision.  Any extension
notice concerning a disability benefit claim will also explain the standards
on which entitlement to a


				-25-





benefit is based, the unresolved issues that prevent a decision on the claim
and the additional information needed to resolve those issues.  Further, the
Claimant shall be given forty-five (45) days to provide the specified
information.

	Any adverse benefit determination notice shall describe the specific
reason or reasons for the denial, refer to the specific Plan provisions on
which the termination was based, describe any additional material or
information necessary for the Claimant to perfect his or her claim and
explain why that material or information is necessary, describe the Plan's
review procedures and the time limits applicable to those procedures,
including a statement of the Claimant's right to bring a civil action under
ERISA Section 502(a) following a denial upon review and, for disability
benefit claims, include a statement that a rule, guideline, protocol or other
similar criterion was relied upon in making the adverse determination and
that a copy of that rule, guideline, protocol or other criterion will be
provided free of charge to such Claimant upon request (if an internal rule,
guideline, protocol or other similar criterion was relied upon in making the
adverse determination) or a statement that an explanation of the scientific
or clinical judgment for the determination applying the terms of the Plan to
the Claimant's medical circumstances will be provided free of charge upon
request (if the adverse benefit determination is based on a medical necessity
or experimental treatment or similar exclusion or limit).  If the notification
is made electronically, it must comply with DOL Reg. Section 2520.104b-(1)
(c)(1)(i), (iii) and (iv).

	Upon receipt of an adverse benefit determination, a Claimant may,
within sixty (60) days (one hundred eighty (180) days for disability benefit
claims) after receiving notification of that determination, submit a written
request asking the Committee to review the Claimant's claim.  Each Claimant,
when making his or her request for review of his or her adverse benefit
determination, shall have the opportunity to submit written comments,
documents, records and any other information relating to the claim for
benefits.  Each Claimant shall also be provided, upon request and free of
charge, reasonable access to, and copies of, all documents, records and other
information relevant to such Claimant's claim for benefits.  The review shall
take into account all comments, documents, records and other information
submitted by the Claimant relating to the claim, regardless of whether the
information was submitted or considered in the initial benefit determination.
For disability benefit claims, the review will not afford deference to the
initial adverse benefit determination and will be conducted by an
appropriate named


				-26-





fiduciary of the Plan who is neither the individual who made the adverse
benefit determination that is the subject of the appeal or a subordinate of
that individual.  In deciding an appeal of any adverse benefit determination
concerning a disability benefit claim that is based in whole or in part on a
medical judgment, the appropriate named fiduciary shall (i) consult with a
healthcare professional who has appropriate training and experience in the
field of medicine involved in the medical judgment and (ii) allow for the
identification of medical or vocational experts whose advice was obtained on
behalf of the Plan in connection with the Claimant's adverse benefit
determination, without regard to whether the advice was relied upon in making
the benefit determination, and the healthcare professional engaged for
purposes of the consultation described above will be an individual who is
neither an individual who is consulted in connection with the adverse benefit
determination that is the subject of the appeal or a subordinate of that
individual.  If a Claimant does not submit his or her request for review in
writing within the sixty (60)-day period (one hundred eighty (180)-day period
for disability benefit claims) described above, his or her claim shall be
deemed to have been conclusively determined for all purposes of the Plan and
the adverse benefit determination will be deemed to be correct.

	If the Claimant submits in writing a request for review of the adverse
benefit determination within the sixty (60)-day period (one hundred eighty
(180)-day period for disability benefit claims) described above, the Committee
(or its designee) shall notify (in writing or electronically) him or her of its
determination on review within a reasonable period of time but not later than
sixty (60) days (forty-five (45)-days for disability benefit claims) from the
date of receipt of his or her request for review, unless the Committee (or its
designee) determines that special circumstances require an extension of time.
If the Committee (or its designee) determines that an extension of time for
processing a Claimant's request for review is required, the Committee (or its
designee) shall notify him or her in writing before the end of the initial
sixty (60)-day period (forty-five (45)-day period for disability benefit
claims) and inform him or her of the special circumstances requiring an
extension of time and the date by which the Committee (or its designee) expects
to render its determination on review.  The extension of time will not exceed
sixty (60) days (forty-five (45)-days for disability benefit claims) from the
end of the initial sixty (60)-day period (forty-five (45)-day period for
disability benefit claims).


				-27-





	If the Committee (or its designee) confirms the adverse benefit
determination upon review, the notification will describe the specific reason
or reasons for the adverse determination, refer to the specific Plan
provisions on which the benefit determination is based, include a statement
that the Claimant is entitled to receive, upon request and free of charge,
reasonable access to, and copies of, all documents, records and other
information relevant to the Claimant's claim and include a statement
describing the Claimant's right to bring an action under ERISA Section 502(a),
for disability benefit claims include a statement that a rule, guideline,
protocol, or other similar criterion was relied upon in making the adverse
determination and that a copy of the rule, guideline, protocol or other
similar criterion will be provided free of charge to the Claimant upon
request (if an internal rule, guideline, protocol or other similar criterion
was relied upon in making the adverse determination), a statement that an
explanation of the scientific or clinical judgment for the determination will
be provided free of charge upon request (if the adverse benefit determination
is based on a medical necessity or experimental treatment or similar exclusion
or limit) and the any other required information under DOL Reg. Section
2560.503-1.  In all events, the claims procedure described above shall be
administered in a manner not inconsistent with ERISA Section 503 and DOL Reg.
Section 2560.503-1.


				-28-





				SECTION 9

			AMENDMENT AND TERMINATION
			-------------------------

	9.1	In General.  Subject to Section 9.2 hereof, the Committee may
at any time amend or terminate any or all of the provisions of the Plan in any
manner; provided, however, that in no event shall any such amendment or
termination adversely affect the right of any Participant or Beneficiary to a
payment under the Plan on the basis of amounts allocated to the Excess Benefit
Account of a Participant as of the date of such amendment or termination or
cause the Plan to fail to satisfy the requirements of Code Section 409A (unless
such intended failure is specifically described in the Committee's resolutions
adopting such amendment).  In the event that the Plan is discontinued with
respect to future Excess Benefit Credits or terminated, each Participant's
Excess Benefit Account Balance shall be distributed in accordance with, and
subject to the requirements of, Section 5.  Notwithstanding any provision to
the contrary in the Plan, nothing shall restrict the Committee's right to
amend the Plan, without the consent of Participants and without additional
consideration to affected Participants, to the extent necessary to avoid
taxation and/or penalties arising under Code Section 409A, even if such
amendments reduce, restrict or eliminate rights or benefits granted under
the Plan.

	9.2	Termination After Change in Control.  Notwithstanding Section
9.1, the Committee may not amend or terminate the Plan without the prior
written consent of all Participants following a Change in Control, provided
that each Participant's Excess Benefit Account Balance shall be distributed
in accordance with, and subject to the requirements of, Section 5.


				-29-





				SECTION 10

			 MISCELLANEOUS PROVISIONS
			 ------------------------

	10.1	Information to be Furnished by Participants and Beneficiaries
and Inability to Locate.  Any communication, statement or notice addressed to a
Participant or to a Beneficiary at his or her last address as shown on the
records of the Company shall be binding on the Participant or Beneficiary for
all purposes of the Plan.  Neither the Company nor the Committee shall be
obliged to search for any Participant or Beneficiary beyond the sending of a
certified or registered mail letter to such last known address.  If the
Company or the Committee (or its designee) notifies any Participant or
Beneficiary that he or she is entitled to an amount under the Plan and the
Participant or Beneficiary fails to claim such amount or make his or her
continued life and location known to the Company or the Committee (or its
designee) before any reasonable search for such Participant or Beneficiary has
concluded, any check that is intended to pay any portion of such amount payable
under the Plan and that remains outstanding when such reasonable search has
concluded shall be voided and the Participant's Excess Benefit Account shall
continue to reflect all unpaid amounts, except as provided herein.  If the
Company or Committee (or its designee) determines that the continued life or
location of the Participant or Beneficiary, as applicable, cannot be
determined, the Company or the Committee (or its designee) shall have the
right to direct that the amount payable shall be deemed to be a forfeiture.

	10.2	Right of the Company to Take Employment Actions.  The
maintenance of the Plan shall not be deemed to constitute a contract between
the Company and any Employee, or to be a consideration for, or an inducement
or condition of, the employment of any Employee.  Nothing herein contained,
or any action taken hereunder, shall be deemed to give an Employee the right
to be retained in the employ of the Company or to interfere with the right of
the Company to discipline or discharge an Employee at any time, nor shall it
be deemed to give to the Company the right to require the Employee to remain
in its employ, nor shall it interfere with any rights of the Employee to
terminate his employment at any time.

	10.3	No Alienation of Assignment of Benefits.  The rights and
interest of a Participant under the Plan shall not be assigned or transferred,
either voluntarily or by operation of law or otherwise, except as otherwise
provided herein, and the rights of a Participant to payments under the Plan
shall not be subject to alienation, attachment, execution, levy, pledge or


				-30-





garnishment by or on behalf of creditors (including heirs, beneficiaries, or
dependents) of the Participant or a Beneficiary.

	10.4	Construction.  All legal questions pertaining to the Plan
shall be determined in accordance with the laws of the State of Ohio, without
reference to conflict of laws provisions, to the extent such laws are not
superseded by ERISA or any other federal law.  Consistent with the preceding
sentence, any reference to the term "spouse" in this Plan shall mean the person
of the opposite sex to whom the Participant or Selected Employee is legally
married as husband and wife.  For purposes of the preceding sentence and Plan,
no individual will be considered to be married unless such marriage is a legal
union between one man and one woman as husband and wife, and in no event shall
a legal union, civil union or any other union between two individuals of the
same sex be treated as a marriage under the Plan.

	10.5	Headings.  The headings of the Sections of the Plan are for
reference only.  In the event of a conflict between a heading and the contents
of a Section, the contents of the Section shall control.

	10.6	Agent for Legal Process.  The Company shall be the agent for
service of legal process with respect to any matter concerning the Plan, unless
and until the Company designates some other person as such agent.

	10.7	Tax Treatment.  Although the Committee (or its designee) shall
use its best efforts to avoid the imposition of taxation and penalties under
Code Section 409A, the tax treatment of Excess Benefit Credits is not warranted
or guaranteed.  Neither the Company, the Board, nor the Committee (or its
designee) shall be held liable for any taxes, penalties or other monetary
amounts owed by any Participant, Employee, Beneficiary or other taxpayer as a
result of the Plan.
