   3
         Such offsets shall be determined using the actuarial factors provided 
in the Lubrizol Pension Plan.


         SECTION 4. EARLY RETIREMENT ELIGIBILITY AND DETERMINATION OF BENEFIT.
Each Participant who retires from employment with the Company at or after age
55, but prior to his Normal Retirement Date, shall receive a percentage of his
supplemental retirement benefit determined under Section 3, in accordance with
the early retirement schedule provided in the Lubrizol Pension Plan.

         SECTION 5. TERMINATION OF EMPLOYMENT.  If a Participant terminates
employment prior to age 55, he shall receive the actuarial equivalent of his
supplemental retirement benefit determined under Section 3 in a single lump-sum
payment; such actuarial equivalent of which shall be calculated using the same
actuarial factors and interest rates used in the Lubrizol Pension Plan as in
effect on the date the Participant terminates employment in accordance with
this Section 5.

         SECTION 6. STANDARD FORM OF BENEFIT.  The Participant shall be paid
his supplemental retirement benefit under this Plan in the form of a monthly
retirement benefit payable to such Participant for his lifetime following his
retirement under Sections 3 or 4, with the continuance to his Beneficiary of
such amount after his death for the remainder, if any, of the 120-month term
commencing 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.

         SECTION 7. OPTIONAL FORMS OF BENEFIT.  Upon becoming eligible to
receive a supplemental retirement benefit under this Plan, the Participant may
elect to receive the actuarial equivalent of the standard form of benefit
provided in Section 6, in accordance with any one of the following options:

         a.      for Participants hired prior to February 1, 1984, a single
                 lump-sum payment;

         b.      a reduced monthly retirement benefit payable to a Participant
                 for his lifetime following his retirement under Sections 3 or
                 4, with the continuance of a monthly benefit equal to fifty
                 percent (50%) of such reduced amount after his death to his
                 Beneficiary, provided that such Beneficiary is living at the
                 time of such Participant's retirement or termination and
                 survives him;

         c.      a reduced monthly retirement benefit payable to such
                 Participant for his lifetime following his retirement under
                 Sections 3 or 4, 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 alive at the time of
                 such Participant's retirement or termination and survives him;
                 or

         d.      annual installments of up to ten payments, the first of which
                 shall be paid within 30 days of the Participant's retirement
                 under Sections 3 or 4, or
   4
                 termination under Section 5, 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 in accordance with the provisions of Section 9,
is less than $25,000, such benefit shall be paid in a single lump-sum payment
to such person.

         SECTION 8. PAYMENT IN THE EVENT OF DEATH PRIOR TO COMMENCEMENT OF
DISTRIBUTION.  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 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 8, 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 8, 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 9. ACTUARIAL FACTORS.  All actuarial assumptions and factors
used in this Plan shall be the same as those used in the Lubrizol Pension Plan.

         SECTION 10.  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 11.  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.
   5
         SECTION 12.  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 13.  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 14.  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 15.  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 16.  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 17.  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.
