Delay for Payments in Violation of Federal Securities Laws or Other Applicable Law. In the event the Company reasonably anticipates that the payment of benefits as specified hereunder would violate Federal securities laws or other applicable law, the Committee may delay the payment of such benefit hereunder until the earliest date at which the Company reasonably anticipates that the making of such payment would not cause such violation.

Delay for Insolvency or Compelling Business Reasons. In the event the Company determines that the making of any payment of benefits on the date specified hereunder would jeopardize the ability of the Company to continue as a going concern, the Committee may delay the payment of such benefits until the first calendar year in which the Company notifies the Committee that the payment of benefits would not have such effect.

Administrative Delay in Payment. The payment of benefits hereunder shall begin at the date specified in accordance with the provisions of the foregoing paragraphs of this Section IV; provided that, in the case of administrative necessity, the payment of such benefits may be delayed up to the later of the last day of the calendar year in which payment would otherwise be made or the 15^th day of the third calendar month following the date on which payment would otherwise be made. Further, if, as a result of events beyond the control of the Participant, it is not administratively practicable for the Committee to calculate the amount of benefits due to the Participant as of the date on which payment would otherwise be made, the payment may be delayed until the first calendar year in which calculation of the amount is administratively practicable.

Claims for Benefits. The Committee shall determine the rights of any Participant to any benefits hereunder. Any Participant who believes that he has not received the benefits to which he is entitled under the Plan may file a claim in writing with the Committee. The Committee shall, no later than 90 days after the receipt of a claim (plus an additional period of 90 days if required for processing, provided that notice of the extension of time is given to the claimant with the first 90-day period), either allow or deny the claim in writing.

specific reference to pertinent Plan provisions on which the denial is based;

a description of any additional material or information necessary for the claimant to perfect the claim and an explanation of why such material or information is necessary; and

an explanation of the claim review procedure and the time limits applicable to such procedures, including a statement of the claimant’s right, if applicable, to bring a civil action under Section 502(a) of ERISA.

Appeal Provisions. A claimant whose claim is denied (or his duly authorized representative) may within 60 days after receipt of denial of a claim file with the Committee a written request for a review of such claim. If the claimant does not file a request for review of his claim within such 60-day period, the claimant shall be deemed to have acquiesced in the original decision of the Committee on his claim, the decision shall become final and the claimant will not be entitled to bring a civil action under Section 502(a) of ERISA. If such an appeal is so filed within such 60-day period the Committee (or its delegate) shall conduct a full and fair review of such claim. During such review, the claimant (or the claimant’s authorized representative) shall be given the opportunity to review all documents that are pertinent to his claim and to submit issues and comments in writing.

The Board, or its delegate, may, in its sole discretion, terminate, suspend or amend this Plan at any time, in whole or in part. However, the termination, amendment or suspension of this Plan will not operate to decrease the benefit to which a Participant has become entitled but which has not yet been paid. Notwithstanding the foregoing, the Plan shall automatically terminate, without further action of the Company, upon Insolvency of the Company. For this purpose, Insolvency shall mean the inability of the Company to continue as a going concern.

Notwithstanding any provision of the Plan to the contrary, the Committee may at any time (without the consent of any Participant) modify, amend or terminate any or all of the provisions of this Plan to the extent necessary to conform the provisions of the Plan with Section 409A of the Code, regardless of whether such modification, amendment or termination of this Plan shall adversely affect the rights of a Participant under the Plan.

Nothing contained herein will confer upon any Participant the right to be retained in the service of the Company, nor will it interfere with the right of the Company to discharge or otherwise deal with a Participant without regard to the existence of this Plan.

No benefit under this Plan shall be assignable or subject to any manner of alienation, sale, transfer, claims of creditors, pledge, attachment or encumbrances of any kind.

The Committee may adopt rules and regulations to assist it in the administration of the Plan and may delegate such of its duties hereunder as it may deem advisable.

This Plan is established under and will be construed according to the laws of the State of Texas, except to the extent preempted by federal law.

This amendment and restatement is signed this 1st day of May, 2013, to be effective as of the date of execution.
