(a) Each Participant who separates from service with the Company and its related corporations shall receive payment of his supplemental
pension benefit in the standard form of payment of a single lump-sum payment payable the later of the six- month anniversary following the separation from service or within 30 days following the calendar year in which Participant separated from
service.

(b) At least 12 months prior to the distribution date specified in paragraph (a) Participants may instead
elect to receive the actuarial equivalent of the benefit determined under Section 2.2 on the date of separation from service, and payable commencing at least five years after the distribution date specified in paragraph (a) above in
accordance with any one of the following options:

(i) Substantially equal monthly payments will be made to the Participant
for his lifetime 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.

(ii) A reduced monthly retirement benefit of substantially equal payments payable to such
Participant for his lifetime with the continuance of a monthly benefit equal to fifty percent (50%) of such reduced amount after his death to the Participants Beneficiary during the lifetime of the Beneficiary, provided that such
Beneficiary is living at the time of such Participants separation from service and survives such Participant.

(iii) A
reduced monthly retirement benefit of substantially equal payments payable to such Participant during his lifetime with the continuance of a monthly benefit equal to one hundred percent (100%) of such reduced amount after his death to the
Participants Beneficiary during the lifetime of the Beneficiary, provided such Beneficiary is living at the time of such Participants separation from service and survives such Participant.

(v) Effective January 1, 2005, a single lump-sum payment.

Monthly payments made after the first payment will be made on the monthly anniversary of the first payment.

(c) Notwithstanding the foregoing, if the Participant is entitled to a benefit under The Lubrizol Corporation 2005 Officers
Supplemental Retirement Plan, the benefit under this Plan shall be paid at the same time and in the same form of payment as the benefit under The Lubrizol Corporation 2005 Officers Supplemental Retirement Plan.

The forms of payment described shall be calculated using the same actuarial factors and interest rates used under The Lubrizol Corporation Pension Plan
(or its successor) as in effect on the date of separation from service.

3.2 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 retired on the day before his death and had elected to receive his benefit under the Lubrizol Pension Plan in a 50 percent joint and survivor annuity form. In making the determinations and reductions
required in this Section 3.2, 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 3.2, if such spouse had been
married to the deceased Participant for at least one year as of the date of the Participants death. Benefits hereunder shall commence within 60 days after the death of the Participant and shall be paid monthly in substantially equal payments
for the life of the surviving spouse.
