In the event payment of a Retirement Benefit is deferred pursuant to this Section, such deferral shall not affect the time of payment or amount of any other installment of such Participant's Retirement Benefit, unless such other payment is itself deferred pursuant to this Section.

All Death Benefit payments pursuant to this Section 5.3 shall cease upon the earlier to occur of (1) the date of death of such Surviving Spouse or (2) the payment of fifteen annual Death Benefit installments to such Surviving Spouse. 5.4 The preceding Sections of this Article notwithstanding, no Death Benefit shall be paid to a Surviving Spouse to the extent such payment, when added to all other remuneration provided to the deceased Participant by the Company or any related entity, would result in any such amount being nondeductible under section 162(m) of the Internal Revenue Code of 1986, as amended, and the payment of any such Death Benefit shall be deferred to the first subsequent year in which such payment may be both paid and fully deductible by the Company. In the event payment of a Death Benefit is deferred pursuant to this Section, such deferral shall not affect the time of payment or amount of any other installment of such Death Benefit, unless such other payment is itself deferred pursuant to this Section.

ADMINISTRATION OF PLAN 7.1 The plan shall be administered by the Committee. Each member of the Committee shall be appointed by the Board and shall serve in accordance with applicable rules and procedures of the Board and the Committee. 7.2 The Committee shall supervise the administration of the Plan according to the terms and provisions hereof and shall have the sole discretionary authority and all of the powers necessary to accomplish these purposes, including, without limitation, the sole discretionary authority to interpret and construe all Plan terms and to make all factual determinations associated with the Plan. All such interpretations, constructions, and determinations shall be final and binding upon all persons. No member of the Committee shall be liable to any person for any action taken or omitted in connection with the administration of the Plan unless attributable to his own willful misconduct or lack of good faith. VIII. UNFUNDED NATURE OF PLAN 8.1 The Plan is intended to constitute an unfunded, unsecured plan of deferred compensation for a select group of management or highly compensated employees of the Company. Further, it is the intention of the Company that the Plan be unfunded for purposes of the Code and Title I of the Employee Retirement Income Security Act of 1974, as amended. The Plan constitutes a mere promise by the Company to make benefit payments in the future. Plan benefits hereunder provided are to be paid out of the Company's general assets, and the Participants shall have the status only of, and shall have no better status than, general unsecured creditors of the Company. 8.2 The Board, in its sole discretion, may select the Trustee, establish the Trust, and enter into the Trust Agreement with the Trustee. Any such Trust established by the Board, and any assets held by such Trust to assist the Company in meeting its obligations under the Plan, shall conform to the terms of the model rabbi trust set forth in Revenue Procedure 92-64, 1992-2 C.B. 422. The Company may transfer money and/or other property to the Trustee, and the Trustee shall pay Plan benefits to Participants and their beneficiaries out of the Trust assets if such benefits are not paid by the Company. In the event the Trust is established, the Company shall remain the owner of all assets in the Trust, and the assets shall be subject to the claims of Company creditors in the event (and only in the event) the Company ever becomes Insolvent. No Participant or beneficiary shall have any preferred claim to, any security interest in, or any beneficial ownership interest in any assets of the Trust. 8.3 The Board and the Chief Executive Officer of the Company shall each have the duty to inform the Trustee in writing if the Company becomes Insolvent. Such notice given -6- under the preceding sentence by any one party shall satisfy each party's duty to give notice. When so informed, the Trustee shall suspend payments to the Participants and Surviving Spouses and hold the assets for the benefit of the Company's general creditors and shall determine within the period specified in the Trust Agreement, or, in the absence of a specified period, within a reasonable period of time, whether the Company is Insolvent. If the Trustee determines that the Company is not Insolvent, the Trustee shall resume payments to the Participants and Surviving Spouses. IX. AMENDMENT AND TERMINATION 9.1 The Board may, in its discretion, amend the Plan, in whole or in part, at any time; provided, however, that no amendment shall be made that would reduce the vested accrued benefit of any Participant as of the later of the adoption date or effective date of such amendment. 9.2 The Board may, in its discretion, terminate the Plan, in whole or in part, at any time. In the event the Plan is terminated, notwithstanding any other provision of the Plan, the Board, in its discretion, may pay each Participant his payable but unpaid vested accrued Retirement Benefit (or, in the case of a deceased Participant, such Participant's Surviving Spouse any payable but unpaid Death Benefit) either in accordance with Articles IV and V or in any other manner it deems appropriate, including, without limitation, a lump sum payment of the actuarial equivalent present value of such unpaid Retirement Benefit or Death Benefit, actuarially reduced to take into account an earlier time of payment. In determining actuarial equivalency for purposes of the preceding sentence, reasonable actuarial assumptions shall be used, and the actuarial calculation shall be made by an actuary selected by and in the discretion of the Board and agreed to by the Participants. X. RESTRICTIONS ON ASSIGNMENT 10.1 The interest of a Participant in the Plan or of his beneficiary or beneficiaries hereunder may not be anticipated, sold, transferred, assigned, or encumbered in any manner, either voluntarily or involuntarily, and any attempt to anticipate, alienate, sell, transfer, assign, pledge, encumber, or charge the same shall be null and void. 10.2 The benefits provided hereunder shall not be liable for, or subject to the debts, contracts, liabilities, engagements, or torts of, any person to whom such benefits are payable, nor shall they be subject to garnishment, attachment, or other legal or equitable process, nor shall they be an asset of the bankrupt's estate in bankruptcy. -7- XI. EFFECT OF PLAN ON EMPLOYMENT OR COMPENSATION 11.1 Nothing contained in the Plan or in the adoption of the Plan shall confer on any person the right to continued employment with the Company or affect in any way the right of the Company to terminate the employment or services of such person at any time. 11.2 Nothing contained in the Plan shall be construed to effect the provisions of any other plan maintained by the Company or shall prevent the Company from adopting or continuing in effect other or additional compensation arrangements affecting any Participant. XII. BINDING EFFECT 12.1 The plan shall be binding upon, and inure to the benefit of, the Company, its successors, and assigns, and the Participants and their respective heirs, executors, administrators, and legal representatives. XIII. SEVERABILITY 13.1 In case any provision of the Plan is determined by a court of competent jurisdiction to be illegal, invalid, or unenforceable for any reason, such illegal, invalid, or unenforceable provision shall not affect the remaining provisions of the Plan, and the Plan shall be construed and enforced as if such illegal, invalid, or unenforceable provision had not been included therein. XIV. JURISDICTION 14.1 Except to the extent federal law applies and preempts state law, the Plan shall be construed, enforced, and administered according to the laws of the state of Texas, excluding any conflict-of-law rule or principle that might refer construction of the Plan to the laws of another state or country. In the event of litigation relating to the Plan, such litigation shall be brought in state or federal court residing in Houston, Harris County, Texas, and the Company and each Participant (or persons claiming rights of or through a Participant) irrevocably appoints the Secretary of State for the state of Texas as agent for receipt of service of process in connection with such litigation. -8- XV.
