The value shall also be adjusted for any (i) all Participant and Employer contribution credits made since the last Valuation Date and (ii) payments made to the Participant (or his or her beneficiary) since that date.

6.2.Transfers to Employer Grantor Trust. The Employer may (but is not required to) transfer to a Trust an amount equal to the amounts credited at any time to Employee Deferral Accounts under Section 4.1, and Discretionary Employer Contribution Accounts under Section 5.1 for its Employees at such time as it deems appropriate. Title to and beneficial ownership of the assets of the Trust shall at all times remain with the Employer and Participants shall not have any property interest whatsoever in such assets.

Additionally, to the extent that a Participant is a “specified employee” as determined as required by Section 409A shall not receive a distribution, following their Separation of Service for at least six months following their Separation of Service. Any subsequent distributions as a result of a Participant's election to be paid upon Retirement shall be made as provided by this Plan.

(b)     The determination of the amount to be distributed under this Section shall be based upon the value of the Participant's vested Accounts as of the last Valuation Date preceding the date of distribution, determined in accordance with Section 6.1. The amount of each installment payment hereunder shall be determined by dividing the value of the Accounts as of the last Valuation Date by the number of installments if any remaining to be paid (including the current installment).

(c)     Any payments to be made hereunder, payment shall be paid on or about February 15 of each year.

7.2.Number/Form of Distribution Options. Notwithstanding the foregoing, the Administrative Committee may, in its sole discretion consistent with Code Section 409A, limit the number or forms of distributions that a Participant may elect to have under Section 7.1.

Such payment shall be made in a lump sum no later than sixty (60) days after the Administrative Committee's decision to approve the payment.

(c)     Notwithstanding the foregoing, a Participant may not receive a payment under subsection (a) above to the extent that the Unforeseeable Financial Emergency is or may be relieved (i) through reimbursement or compensation by insurance or otherwise, (ii) by liquidation of the Participant's assets, to the extent the liquidation of such assets would not itself cause severe financial hardship or (iii) by suspension of deferrals under this Plan (to the extent permitted under Code Section 409A).

8.1.Form and Payment of Death Benefits.

(a)     Upon a Participant's death, the Participant's vested Accounts, if any, shall be paid to the Participant's beneficiary (determined in accordance with Section 8.2) in a single lump sum payment.

(b)     The amount of the death benefit to be paid to a beneficiary hereunder shall be determined in accordance with Section 7.

8.2.Participant's Beneficiary.

(a)     If a Participant is married at the time of his or her death, the Participant's beneficiary shall be his or her Spouse, unless the Participant names another beneficiary in accordance with subsection (c) below and the named beneficiary is alive (or, in the case of a trust, in existence) on the Participant's date of death.

(b)     If a Participant is not married at the time of his or her death, the Participant's beneficiary shall be the individual or trust the Participant has designated in accordance with subsection (c) below prior to his or her death.

The interpretation and construction of the Plan by the Administrative Committee (or its delegate), and any action taken hereunder, shall be final, binding and conclusive upon all parties in interest. Neither the Administrative Committee nor any of its agents or employees shall be liable to any person for any action taken or omitted to be taken in connection with the interpretation, construction or administration of this Plan, so long as such action or omission to act is made in good faith.

No other Employer or other person or entity shall be liable for such payments.

No amendment shall be made to this Article or other Plan provisions regarding Administrative Committee authority under the Plan without prior approval by the Administrative Committee.

9.6.Indemnity of Committee. The Company shall indemnify and hold harmless the members of the Administrative Committee against any and all claims, loss, damage, expense or liability arising from any action or failure to act with respect to this Plan on account of such person's service on the Administrative Committee, except in the case of willful misconduct.

10.1.Amendment, Suspension and Termination.

(a)     The Company reserves the right to amend the Plan by action of the Board or the Compensation Committee of the Board; provided, that the Company's CEO and Administrative Committee may amend the Plan without such prior authorization in the following circumstances:

(i)    The Company's CEO may amend the Plan in any respect to the extent that the amendment does not result in an annual increase in the cost of maintaining the Plan in excess of $250,000.

(ii)    The Administrative Committee may, to the extent that the amendment does not result in an annual increase in the cost of maintaining the Plan in excess of $100,000, amend the Plan to:

(B)    Maintain the Plan's status as a “top-hat” plan for purposes of ERISA; or

(C)    Comply with applicable law or Internal Revenue Service regulations.

Any amendment adopted by the Administrative Committee may be signed by any member of the Committee. Notwithstanding the foregoing, no amendment shall deprive a Participant of his or her Accounts hereunder determined as of the date of such amendment.

(b)     Each Employer reserves the right by action of its board of directors (or by such other means as may be prescribed by the Board or the Compensation Committee of the Board) to withdraw from the Plan with respect to its Eligible Executives and Participants or suspend the accrual of further benefits under Section 4.1, 5.1 or 5.2 at any time. No such withdrawal or suspension shall deprive a Participant of his or her vested Accounts as of the date of withdrawal or suspension.

(c)     The Company reserves the right by action of the Board or the Compensation Committee of the Board to terminate the Plan at any time; provided that upon termination, no Participant shall be deprived of his or her vested Accounts hereunder determined as of the date of termination.

10.2.Transfer of Accounts. If an Eligible Employee ceases to be an Eligible Employee on account of becoming eligible for the Company's Executive Deferred Compensation Plan, the liability for the Employee's Accounts shall, to the extent provided by the Administrative Committee in its sole discretion, be transferred to and made a part of the Employee's account payable under that Plan; provided, that the payment (and other relevant aspects) of such transferred Accounts shall, to the extent necessary to comply with Code Section 409A, be handled in accordance with the terms of this Plan in effect on the date of transfer.

10.3.Nontransferability of Benefits. The rights of a Participant and any beneficiary under the Plan are not subject to the claims of their creditors and may not be voluntarily or involuntarily transferred, assigned, alienated, accelerated or encumbered. Notwithstanding the preceding sentence, the Accounts payable to a Participant under the Plan may, consistent with the requirements of Code Section 409A, be offset by any liability of the Participant owing to the Employer or any Affiliate.

10.4.Participant's Rights Unsecured. The Plan is intended to be unfunded for purposes of both the Code and ERISA. The right of a Participant or his or her beneficiary to receive payment of the Participant's Accounts hereunder shall be a general unsecured claim against the Employer's general assets, and neither the Participant nor his or her beneficiary shall have any rights in or against any amount credited to any investment account, Trust, or any other specific assets of the Employer. To the extent that any person acquires a right to receive payments from an Employer under the Plan, such right shall be no greater than the right of any general unsecured creditor of the Employer.

10.5.Domestic Relations Orders. If a court determines that a Spouse or former Spouse of a Participant has an interest in the Participant's vested Accounts under a final domestic relations order, the Administrative Committee (or its delegate) may, in its sole discretion consistent with Code Section 409A, distribute the Spouse's or former Spouse's interest to that Spouse or former Spouse in accordance with such order.

10.6.Applicable Law. This Agreement shall be construed and enforced in accordance with the laws of the State of Texas, to the extent applicable.

A Participant shall cooperate with the Employer or Administrative Committee by furnishing any and all information requested by the Employer or Administrative Committee in order to facilitate the payment of benefits hereunder, and by taking such physical examinations as the Employer or Administrative Committee may deem necessary and taking such other action as may be requested by the Employer or Administrative Committee.

10.9.Effect on Employment Rights. Nothing in this Plan shall be construed as (a) giving any Participant any right to continued employment with an Employer or any Affiliate, or (b) affecting the eligibility for, or calculation of, any benefit provided to any Participant by the Employer to the extent permitted by law. No Participant shall have the right to receive any benefit under the Plan except in accordance with the Plan's terms.

10.10.Severability. If any provision of the Plan shall be held invalid or unlawful for any reason, such event shall not affect or render invalid or unenforceable the remaining provisions of the Plan.

10.11.Notice. Any notice, consent, election, claim or demand required or permitted to be given under the provisions of this Plan shall be in writing, and shall be signed by the party giving or making the same. If such notice, consent, election, claim or demand is to be mailed, it shall be sent by United States certified mail, postage prepaid, addressed to the addressee's last known address. The date of such mailing shall be deemed the date of notice, consent, election, claim or demand.

10.12.Tax Liability. Any required federal, state or local tax withholding may be withheld from any payment made pursuant to this Plan or from any other compensation payable to the Participant. Notwithstanding the foregoing, a Participant may, to the extent permitted by the Administrative Committee consistent with Code Section 409A, elect to pay any required employment taxes (and any resulting income taxes) that arise as of the date of deferral (or, if later, vesting) hereunder either (a) by direct payment or (b) through the withholding of such amounts from other compensation due the Participant. In the alternative, the Administrative Committee may, in its sole discretion, offset such taxes against the Participant's vested Accounts to the extent permitted under Treas. Reg. Section 1.409A-3(j)(4) or other applicable regulations.

10.13.No Guarantee of Benefits. Nothing in this Plan shall constitute a guarantee by Employer, Company, Administrative Committee or any other person or entity that the Employer's assets will be sufficient to pay any benefits hereunder.

10.14.Incapacity of Recipient. If the Administrative Committee determines that any person to whom any benefits are payable hereunder is (a) unable to care for his or her affairs because of illness or accident or (b) a minor, any payment due under the Plan may be paid to the duly appointed guardian or conservator of such person or to any third party who is eligible to receive payment from the Plan for the account of such person. Any such payment shall be a complete discharge of the Employer's liability for such payments hereunder.

10.15.Construction. Titles of articles and sections herein are for convenience of reference only and are not to be taken into account in interpreting the Plan. The masculine whenever used herein shall include the feminine.
