provided hereunder shall be satisfied by the Corporation out of its general
funds. In order to provide a source of payment for its obligations under the
Plan, the Corporation will cause a trust fund to be maintained and/or arrange
for insurance contracts. Subject to the provisions of the trust agreement
governing any such trust fund or the insurance contract, the obligation of the
Corporation under the Plan to provide a benefit shall nonetheless constitute
the unsecured promise of the Corporation to make payments as provided herein,
and no person shall have any interest in, or a lien or prior claim upon, any
property of the Corporation.

         Section 4. PAYMENT OF BENEFITS. Payment of any death benefit under the
Plan shall be made to the decreased Participant's beneficiary in a single lump
sum as soon as practicable after the Participant's death.

         Section 5. BENEFICIARIES. A Participant may designate any person or
person as a beneficiary (hereinafter referred to as a "Beneficiary") to receive
payment of the death benefit provided under the Plan. Such designation shall be
made in writing in the form prescribed by the plan administrator and shall
become effective only when filed by the Participant with the Corporation. A
Participant may change or revoke his Beneficiary designation at any time by
completing and filing with the Corporation a new Beneficiary designation. If at
the time of the Participant's death there is no Beneficiary designation on file
with the Corporation, or the Beneficiary does not survive to the date of
distribution, the death benefit provided hereunder shall be paid to the
Participant's estate.

         Section 6. PLAN ADMINISTRATOR. The Corporation shall be the
administrator of the Plan. The plan administrator shall perform all ministerial
functions with respect to the Plan. The plan administrator shall employ such
advisors or agents as it may deem necessary or advisable to assist it in
carrying out its duties hereunder. The plan administrator shall have full power
and authority to interpret and construe the Plan and shall determine all
questions arising in the administration, interpretation, and application of the
Plan. Any such determination shall be conclusive and binding on all persons.

         Section 7. REDUCTION OR TERMINATION OF BENEFITS. The Committee
reserves the right to reduce or eliminate the benefit of any Participant who is
dismissed for cause, or who voluntarily terminates employment to obtain
competitive employment.

         For Plan purposes, "Cause" means (i) willful violation of a
Corporation policy, or (ii) willful misconduct or gross negligence in the
performance of duties, as determined by the Corporation in good faith
consistently, if applicable, with its existing personnel practices.

         For Plan purposes, "Competitive employment" shall include employment
with any employer (firm, business, or individual) engaged in selling or
furnishing any product similar to that available from the Corporation at the
time of termination of employment with the Corporation.

         Section 8. EMPLOYMENT. This Plan shall not constitute a contract of
employment.

         Section 9. SEVERABILITY. In the event any provision of the Plan is
deemed invalid, such provision shall be deemed to be severed from the Plan, and
the remainder of the Plan shall continue in full force and effect.

         Section 10. GOVERNING LAW. The provisions of the Plan shall be
construed and enforced in accordance with the laws of the State of Ohio.

         Section 11. EFFECTIVE DATE. The Plan is effective as of June 1, 1990.

                           (ii) effective October 1, 2000, a single lump-sum
                  payment payable within 30 days following the end of the
                  calendar year in which the Participant retires. Interest on
                  the lump-sum deferral shall accrue and be paid with the
                  lump-sum; such interest to be computed at the applicable
                  interest rate, as defined in Section 417(e)(3)(A)(ii)(II) of
                  the Code, in effect on the date of retirement;

                           (iii) a reduced monthly retirement benefit
                  commencing within 30 days following retirement and payable to
                  such Participant for his lifetime following his retirement,
                  with the continuance of a monthly benefit equal to fifty
                  percent (50%) of such reduced amount after his death to his
                  Beneficiary during the lifetime of the Beneficiary, provided
                  that such Beneficiary is living at the time of such
                  Participant's retirement and survives him;

                           (iv) a reduced monthly retirement benefit commencing
                  within 30 days following retirement and payable to such
                  Participant for his lifetime following his retirement, with
                  the continuance of a monthly benefit equal to one hundred
                  percent (100%) of such reduced amount after his death to his
                  Beneficiary during the lifetime of the Beneficiary, provided
                  such Beneficiary is living at the time of such Participant's
                  retirement and survives him.

                           (v) annual installments of up to ten payments, the
                  first of which shall be paid within 30 days following
                  retirement, and subsequent installments of which shall be
                  paid on the anniversary date of the payment of the first
                  installment. Such installments shall be determined by
                  dividing the commuted lump-sum equivalent of the supplemental
                  retirement benefit (determined in the same manner as under
                  the Lubrizol Pension Plan) by the number of installments to
                  be paid and adjusting for interest based on the interest rate
                  used to determine the commuted lump-sum payment. Installments
                  after the first installment shall include such interest which
                  accrues during the 12-month period occurring since the date
                  the prior installment was paid.

         Notwithstanding the foregoing provisions of the Plan to the contrary,
if the present actuarial value of any retirement benefit or survivor benefit
under the Plan to any person, determined as described above, is less than
$25,000, such benefit shall be paid in a single lump-sum payment to such person
within 30 days following retirement.

         Section 7. PAYMENT IN THE EVENT OF DEATH PRIOR TO COMMENCEMENT OF
DISTRIBUTION. Effective February 26, 2001, if a Participant dies prior to
commencement of benefits under the Plan, his surviving spouse, if any, shall be
eligible for a survivor benefit which is equal to one-half of the reduced
monthly benefit the Participant would have received under the Plan if the
Participant was 100 percent vested in his accrued supplemental retirement
benefit, had terminated employment on the day before his death and had elected
to receive his benefit hereunder in the form of a 50 percent joint and survivor
annuity. In

making the determinations and reductions required in this Section 7, the
Company shall apply the assumptions then in use under the Lubrizol Pension
Plan. For purposes hereof, a surviving spouse shall only be eligible for a
benefit under this Section 7, if such spouse had been married to the deceased
Participant for at least one year as of the date of the Participant's death.

         Section 8. ACTUARIAL FACTORS. All actuarial assumptions and factors
used in this Plan shall be the same as those used in the Lubrizol Pension Plan.

         Section 9. FUNDING. The obligation of the Company to pay benefits
provided hereunder shall be unfunded and unsecured and such benefits shall be
paid by the Company out of its general funds. In order to provide a source of
payment for its obligations under the Plan, the Company may cause a trust fund
to be maintained and/or arrange for insurance contracts. Subject to the
provisions of the trust agreement governing any such trust fund or the
insurance contract, the obligation of the Company under the Plan to provide a
Participant with a benefit shall nonetheless constitute the unsecured promise
of the Company to make payments as provided herein, and no person shall have
any interest in, or a lien or prior claim upon, any property of the Company.

         Section 10. PLAN ADMINISTRATOR. The Company shall be the plan
administrator of the Plan. The plan administrator shall perform all ministerial
functions with respect to the Plan. Further, the plan administrator shall have
full power and authority to interpret and construe the Plan and shall determine
all questions arising in the administration, interpretation, and application of
the Plan. Any such determination shall be conclusive and binding on all
persons. The plan administrator shall employ such advisors or agents as it may
deem necessary or advisable to assist it in carrying out its duties hereunder.

         Section 11. NOT A CONTRACT OF CONTINUING EMPLOYMENT. Nothing herein
contained shall be construed as a commitment or agreement on the part of the
Participant to continue his employment with the Company, and nothing herein
contained shall be construed as a commitment or agreement on the part of the
Company to continue the employment or the annual rate of compensation of the
Participant for any period, and the Participant shall remain subject to
discharge to the same extent as if this Plan had never been put into effect.

         Section 12. RIGHT OF AMENDMENT AND TERMINATION. Effective October 1,
1994, the Company reserves the right to amend or terminate the Plan in whole or
in part at any time and to suspend operation of the Plan, in whole or in part,
at any time, by resolution or written action of its Board of Directors or by
action of a committee to which such authority has been delegated by the Board
of Directors; provided, however, that no amendment shall result in the
forfeiture or reduction of the interest of any Participant or person claiming
under or through any one or more of them pursuant to the Plan. Any amendment of
the Plan shall be in writing and signed by authorized individuals.

         Section 13. TERMINATION AND DISTRIBUTION OF ACCRUED BENEFITS. The Plan
may be terminated at any time by the Company, and in that event the amount of
the accrued benefits as of the date of such termination shall remain an
obligation of the Company and shall be payable as if the Plan had not been
terminated.

         Section 14. CONSTRUCTION. Where necessary or appropriate to the
meaning hereof, the singular shall be deemed to include the plural, the plural
to include the singular, the masculine to include the feminine, and the
feminine to include the masculine.

         Section 15. SEVERABILITY. In the event any provision of the Plan is
deemed invalid, such provision shall be deemed to be severed from the Plan, and
the remainder of the Plan shall continue to be in full force and effect.

         Section 16. GOVERNING LAW. Except as otherwise provided, the
provisions of the Plan shall be construed and enforced in accordance with the
laws of the State of Ohio.
