         majority vote of the Board of Directors of the Company, a "Change in
         Control" shall not be deemed to have occurred for purposes of this
         Trust Agreement solely because (i) the Company , (ii) an entity in
         which the Company directly or indirectly beneficially owns 50 percent
         or more of the voting securities, or (iii) any Company-sponsored
         employee stock ownership plan or any other employee benefit plan of the

         8-K or Schedule 14A (or any successor schedule, form or report or item
         therein) under the Exchange Act, disclosing beneficial ownership by it
         of shares of Voting Stock, whether in excess of 20 percent or
         otherwise, or because the Company reports that a change in control of
         the Company has or may have occurred or will or may occur in the future
         by reason of such beneficial ownership.

         Section 2. Vesting. Effective February 24, 2003, a Participant who is

the Lubrizol Pension Plan.

         Section 5. Termination of Employment. Effective February 26, 2001, if a
Participant terminates employment prior to age 55, he shall receive the
actuarial equivalent of his vested supplemental retirement benefit determined

the Lubrizol Pension Plan as in effect on the date the Participant terminates
employment in accordance with this Section 5.

         Section 6.   Payment to Participant. (Effective November 27, 1995)

                  (a) Each Participant who retires in accordance with Sections 3
         or 4 shall receive payment of his supplemental pension benefit under
         the Plan determined as of his date of retirement in the standard form
         of benefit of a monthly retirement benefit commencing within 30 days
         following retirement and payable to such Participant for his lifetime
         following such retirement, with the continuance to his Beneficiary of
         such amount after his death for the remainder, if any, of the 120-month
         term that commenced with the date as of which the first payment of such
         monthly benefit is made, and with any such monthly benefits remaining
         unpaid upon the death of the survivor of the Participant and his
         Beneficiary to be made to the estate of such survivor.

         following options:

<PAGE>

                           (i) a single lump-sum payment payable within 30 days
                  following retirement;

                           (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

<PAGE>

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.

<PAGE>

         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.
