ARTICLE II SUPPLEMENTAL PENSION BENEFIT 2.1 Eligibility. A Participant who retires, dies, or otherwise terminates his employment with the Company under conditions which make such Participant eligible for a benefit under the Lubrizol Pension Plan and whose benefits under the Lubrizol Pension Plan are limited by Section 415 of the Code, shall be eligible for a supplemental pension benefit determined in accordance with the provisions of Section 2.2. 2.2 Amount. Subject to the provisions of Article III, the monthly supplemental pension benefit payable to an eligible Participant shall be such an amount which when added to the monthly pension payable (before any reduction applicable to an optional method of payment) to such Participant under the Lubrizol Pension Plan, equals the monthly pension benefit which would have been payable (before any reduction applicable to an optional method of payment) under the Lubrizol Pension Plan to the Participant, if the limita- tions of Section 415 of the Code were not in effect. 2.3 Payment. The terms of payment of the supplemental pension benefit shall be identical to those specified in the Lubrizol Pension Plan for the type of benefit the Participant receives under the Lubrizol Pension Plan. - 2 - 5 ARTICLE III PAYMENT OF BENEFITS 3.1 Payment to Participant. Payment of a supplemental pension benefit under the Plan to a Participant shall be made in the same manner and form applicable to the benefit payable to him under the Lubrizol Pension Plan. The amount of the supplemental pension benefit payable to a Participant shall be adjusted to reflect the method of payment, pursuant to the assumptions then in use under the Lubrizol Pension Plan. 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 bene- fit 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 pur- poses 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. ARTICLE IV ADMINISTRATION The Company shall be responsible for the general administration of the Plan, for carrying out the provisions hereof, and for making, or - 3 - 6 causing the Trust to make, any required supplemental benefit payments. The Company shall have all such powers as may be necessary to carry out the provi- sions of the Plan, including the power to determine all questions relating to eligibility for and the amount of any supplemental pension benefit and all questions pertaining to claims for benefits and procedures for claim review; to resolve all other questions arising under the Plan, including any questions of construction; and to take such further action as the Company shall deem advisable in the administration of the Plan. The Company may delegate any of its powers, authorities, or responsibilities for the operation and administra- tion of the Plan to any person or committee so designated in writing by it and may employ such attorneys, agents, and accountants as it may deem necessary or advisable to assist it in carrying out its duties hereunder. The actions taken and the decisions made by the Company hereunder shall be final and bind- ing upon all interested parties. ARTICLE V AMENDMENT AND TERMINATION The Company reserves the right to amend or terminate the Plan at any time by action of its Board of Directors or its representative or deleg- ate; provided, however, that no such action shall adversely affect any Parti- cipant who is receiving supplemental pension benefits under the Plan, unless an equivalent benefit is provided under the Lubrizol Pension Plan or another plan sponsored by the Company. ARTICLE VI MISCELLANEOUS 6.1 Non-Alienation of Retirement Rights or Benefits. No Par- ticipant shall encumber or dispose of his right to receive any payments - 4 - 7 hereunder, which payments or the right thereto are expressly declared to be non-assignable and non-transferable. If a Participant attempts to assign, transfer, alienate or encumber his right to receive any payment hereunder or permits the same to be subject to alienation, garnishment, attachment, execu- tion, or levy of any kind, then thereafter during the life of such Partici- pant, and also during any period in which any Participant is incapable in the judgment of the Company of attending to his financial affairs, any payments which the Company is required to make hereunder may be made, in the discretion of the Company, directly to such Participant or to any other person for his use or benefit or that of his dependents, if any, including any person fur- nishing goods or services to or for his use or benefit or the use or benefit of his dependents, if any. Each such payment may be made without the inter- vention of a guardian, the receipt of the payee shall constitute a complete acquittance to the Company with respect thereto, and the Company shall have no responsibility for the proper allocation thereof. 6.2 Plan Non-Contractual. Nothing herein contained shall be construed as a commitment or agreement on the part of any person employed by the Company to continue his employment with the Company, and nothing herein contained shall be construed as a commitment on the part of the Company to continue the employment or the annual rate of compensation of any such person for any period, and all Participants shall remain subject to discharge to the same extent as if the Plan had never been established. 6.3 Trust. In order to provide a source of payment for its obligations under the Plan, the Company has established the Trust, the terms of which are governed by the Trust Agreement. 6.4 Interest of a Participant. Subject to the provisions of the Trust Agreement, the obligation of the Company under the Plan to provide a - 5 - 8 Participant with a supplemental pension benefit constitutes 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. 6.5 Controlling Status. No Participant shall be eligible for a benefit under the Plan unless such Participant is a Participant on the date of his retirement, death, or other termination of employment. 6.6 Claims of Other Persons. The provisions of the Plan shall in no event be construed as giving any person, firm or corporation any legal or equitable right as against the Company, its officers, employees, or direc- tors, except any such rights as are specifically provided for in the Plan or are hereafter created in accordance with the terms and provisions of the Plan. 6.7 Severability. The invalidity or unenforceability of any particular provision of the Plan shall not affect any other provision hereof, and the Plan shall be construed in all respects as if such invalid or unen- forceable provision were omitted herefrom. 6.8 Governing Law. The provisions of the Plan shall be governed and construed in accordance with the laws of the State of Ohio. * * * EXECUTED at Wickliffe, Ohio, this 4th day of December , 1986.
