ARTICLE III

PAYMENT OF BENEFITS

3.1 Payment to Participant. (Effective November 27, 1995)

(a) Each Participant who terminates employment with the Company and its related corporations shall receive payment of his supplemental pension benefit under the Plan determined as of his date of termination of employment in the standard form of benefit of a monthly retirement benefit commencing within 30 days following employment termination and payable to such Participant for his lifetime following such employment termination, 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.

(b) Participants may instead elect within a 60 day period commencing 90 days prior to employment termination to receive the actuarial equivalent of the standard form of benefit determined under paragraph (a), on the date of employment termination, in accordance with any one of the following options:

(i) for Participants hired prior to February 1, 1984, a single lump-sum payment payable within 30 days following employment termination;

(ii) effective October 1, 2000, for Participants hired prior to February 1, 1984, a single lump-sum payment payable within 30 days following the end of the calendar year in which the Participant’s employment terminated. 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 the employment termination.

(iii) a reduced monthly retirement benefit commencing within 30 days following employment termination and payable to such Participant for his lifetime following such employment termination, 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 employment termination and survives such Participant;

(iv) a reduced monthly retirement benefit commencing within 30 days following employment termination and payable to such Participant during his lifetime following his termination, 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 termination and survives such Participant.

Such optional forms of payment described above 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 employment termination; provided, however, that for any person who was a Participant as of December 31, 1993, who elects to have his supplemental pension benefit paid in a single lump-sum payment, the interest rate used to discount the portion of the Participant’s supplemental pension benefit which represents his accrued benefit as of December 31, 1993, shall be the arithmetic average of the 7-day compound yield rates for the six full calendar months prior to the month of termination as published in Donoghue’s Tax-Free MONEY FUND AVERAGE which is reported weekly in Barron’s; provided further that such rate with respect to any month shall be the rate reported in the first issue of Barron’s published during such month.

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 employment termination.

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.

3.3 Special Form of Benefit for E. Victor Luoma. Notwithstanding the first sentence of Section 3.1, E. Victor Luoma may elect prior to his retirement or other termination of employment to receive payment of his supplemental pension benefit under the Plan in the form of a single sum amount, determined and payable in accordance with the second and third sentences of Section 3.1.

3.4 Lump Sum Form of Benefit for Roger Y. K. Hsu. Effective January 1, 1996, notwithstanding the provisions of Section 3.1(b), Roger Y. K. Hsu shall receive payment of his supplemental pension benefit under the Plan in the form of a single sum amount.

(b) the specific portions of the denial of his claim which the Claimant requests the Company to review;

(c) a statement by the Claimant setting forth the basis upon which he believes the Company should reverse the Company’s previous denial of his claim for benefits and accept his claim as made; and

Claimant shall be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the Claimant’s claim for benefits. The review of the claim will take into account all comments, documents, records and other

information submitted by the Claimant relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination. Within no later than 60 days of the date determined pursuant to paragraph (a) of this Section 4.2, the Company shall notify Claimant of the Plan’s benefit determination, unless the Company determines that special circumstances require an extension of time for processing the claim.

In no event shall such extension exceed a period of 60 days from the end of the initial period. The extension notice shall indicate the special circumstances requiring an extension of time and the date by which the Plan expects to render the determination on review. The Company shall provide the Claimant with a written notification of the Plan’s benefit determination on review, written in a manner calculated to be understood by the Claimant, including the reasons and Plan provisions upon which its decision was based, 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 for benefits, and a statement of the Claimant’s right to bring an action under Section 502(a) of ERISA.
