Except as defined herein, capitalized terms shall have the same meanings ascribed to them under the Plan.

2.    Terms of Restricted Stock Units. Director hereby accepts the Restricted Stock Units and agrees with respect thereto as follows:

(a)    Forfeiture of Restricted Stock Units. In the event of termination of Director’s membership on the Board of Directors of the Company (the “Board”) for any reason other than (i) death or disability while serving on the Board (disability being defined as being physically or mentally incapable of performing the Director’s usual duties as a member of the Board and such condition is likely to remain continuously and permanently, as determined by the Committee, or its delegate), (ii) failure to be re-elected to the Board after being duly nominated, or (iii) retirement from the Board pursuant to then existing Company policy for mandatory retirement, or except as otherwise provided in the last two sentences of subparagraph (c) of this Paragraph 2, Director shall, for no consideration, forfeit all Restricted Stock Units to the extent they are not fully vested.

(b)    Assignment of Award. The Restricted Stock Units may not be sold, assigned, pledged, exchanged, hypothecated or otherwise transferred, encumbered or disposed of.

(c)    Vesting Schedule. The Restricted Stock Units shall vest in accordance with the following schedule provided that Director has been continuously a member of the Board from the date of this Agreement through the applicable vesting date.

Notwithstanding the foregoing, the Restricted Stock Units shall become fully vested on the earlier of (i) Director’s death or disability (as determined above), (ii) Director’s failure to be re-elected to the Board after being duly nominated while serving as a member of the Board, or (iii) Director’s retirement from the Board pursuant to then existing Company policy for mandatory retirement. In the event Director’s membership on the Board is terminated for any other reason, the Committee that administers the Plan (the “Committee”) or its delegate, as appropriate, may, in the Committee’s or such delegate’s sole discretion, approve the acceleration of the vesting of any or all Restricted Stock Units still subject to restrictions, such vesting acceleration to be effective on the date of such approval or Director’s termination date, if later.

(d)    Stockholder Rights. Director shall have no rights of a stockholder with respect to shares of Stock subject to this Award unless and until such time as the Award has been settled by the transfer of shares of Stock to Director, except that the Director shall have the right to receive payments equal to the dividends or distributions declared or paid on a share of Stock at the same time as those dividends or distributions are paid to holders of Stock.

(e)    Settlement and Delivery of Shares. Payment of vested Restricted Stock Units shall be made as soon as administratively practicable after vesting, but in no event later than thirty days after the vesting date. Settlement will be made by payment in shares of Stock. Notwithstanding the foregoing, the Company shall not be obligated to deliver any shares of Stock if counsel to the Company determines that such sale or delivery would violate any applicable law or any rule or regulation of any governmental authority or any rule or regulation of, or agreement of the Company with, any securities exchange or association upon which the Stock is listed or quoted. The Company shall in no event be obligated to take any affirmative action in order to cause the delivery of shares of Stock to comply with any such law, rule, regulation, or agreement.

3.    Withholding of Tax. The Committee may make such provisions as it may deem appropriate for the withholding of any taxes that it determines is required in connection with this Award. Unless the Committee provides otherwise, the Company shall reduce the number of shares of Stock that would have otherwise been delivered to Director by a number of shares of Stock having a Fair Market Value equal to the amount required to be withheld.

4.    Director Relationship. For purposes of this Agreement, Director shall be considered to be a Director of the Company as long as Director remains a member of the Board. Any question as to whether and when there has been a termination of such membership on the Board, and the cause of such termination, shall be determined by the Committee, or its delegate, as appropriate, and its determination shall be final.

5.    Committee’s Powers. No provision contained in this Agreement shall in any way terminate, modify or alter, or be construed or interpreted as terminating, modifying or altering any of the powers, rights or authority vested in the Committee or, to the extent delegated, in its delegate pursuant to the terms of the Plan or resolutions adopted in furtherance of the Plan, including, without limitation, the right to make certain determinations and elections with respect to the Restricted Stock Units.

6.    Binding Effect. This Agreement shall be binding upon and inure to the benefit of any successors to the Company and all persons lawfully claiming under Director.

7.    Compliance with Law. Notwithstanding anything to the contrary herein, the Company shall not be obligated to issue any Stock in connection with a Restricted Stock Unit, at any time, if the offering or issuance of the Stock, or if acceptance of the Stock by a Director, violates or is not in compliance with any laws, rules or regulations of the United States or any state or country.

8.    Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Texas.

9.    Section 409A. Notwithstanding anything in this Agreement to the contrary, if any provision in this Agreement would result in the imposition of an applicable tax under Section 409A of the Code and related regulations and United States Department of the Treasury pronouncements (“Section 409A”), that provision will be reformed to avoid imposition of the applicable tax and no action taken to comply with Section 409A shall be deemed to adversely affect the Director’s rights under this Agreement.

IN WITNESS WHEREOF, the Company has caused this Agreement to be duly executed by an officer thereunto duly authorized, and Director has executed this Agreement, all as of the date first above written.
