Exercise of Options. An Option shall be deemed exercised when (i) the Company has received written notice of such exercise in accordance with the terms of the Option Agreement, (ii) full payment of the aggregate Option Price of the Shares as to which the Option is exercised has been made, and (iii) arrangements that are satisfactory to the Committee in its sole discretion have been made for the Optionee’s payment to the Company of the amount, if any, that the Committee determines to be necessary for the Company to withhold in accordance with applicable federal or state income tax withholding requirements. Pursuant to procedures approved by the Committee, tax withholding requirements, at the option of an Optionee, may be met by withholding Shares otherwise deliverable to the Optionee upon the exercise of an Option. Unless further limited by the Committee in any Option Agreement, the Option Price of any Shares purchased shall be paid solely in cash, by certified or cashier’s check, by money order, with Shares (but with Shares only if permitted by the Option Agreement or otherwise permitted by the Committee in its sole discretion at the time of exercise) or by a combination of the above; provided, however, that the Committee in its sole discretion may accept a personal check in full or partial payment of any Shares. If the exercise price is paid in whole or in part with Shares, the value of the Shares surrendered shall be their Fair Market Value on the date received by the Company. Any permitted payment through the tender of Shares may be made by instruction from the Optionee to the Company to withhold from the Shares issuable upon exercise that number which have a Fair Market Value equal to the exercise price for the Option or portion thereof being exercised.

8.

(a)

If at any time while this Plan is in effect or unexercised Options are outstanding, there shall be any increase or decrease in the number of issued and outstanding Shares through the declaration of a stock dividend or through any recapitalization resulting in a stock split-up, combination or exchange of Shares, then and in such event:

(i)

appropriate adjustment shall be made in the maximum number of Shares then subject to being optioned under the Plan, so that the same proportion of the Company’s issued and outstanding Shares shall continue to be subject to being so optioned; and

(ii)

appropriate adjustment shall be made in the number of Shares and the exercise price per Share thereof then subject to any outstanding Option, so that the same proportion of the Company’s issued and outstanding Shares shall remain subject to purchase at the same aggregate exercise price.

(b)

Except as otherwise expressly provided herein, the issuance by the Company of Shares of its capital stock of any class, or securities convertible into Shares of capital stock of any class, either in connection with a direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of Shares or obligations of the Company convertible into such Shares or other securities, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number of or exercise price of Shares then subject to outstanding Options granted under this Plan.

(c)

Without limiting the generality of the foregoing, the existence of outstanding Options granted under this Plan shall not affect in any manner the right or power of the Company to make, authorize or consummate (1) any or all adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business; (2) any merger or consolidation of the Company; (3) any issue by the Company of debt securities, or preferred or preference stock which would rank above the Shares subject to outstanding Options; (4) the dissolution or liquidation of the Company; (5) any sale, transfer or assignment of all or any part of the assets or business of the Company; or (6) any other corporate act or proceeding, whether of a similar character or otherwise.

9.

Transferability of Options. Each Option Agreement shall provide that such Option shall not be transferable by the Optionee other than by will or by the laws of descent and distribution provided, however, that the Committee, in its sole discretion may allow for the transferability of any option previously granted or to be granted pursuant to this Plan.

10.

Issuance of Shares. No person shall be, or have any of the rights or privileges of, a Shareholder of the Company with respect to any of the Shares subject to an Option, unless and until certificates representing such Shares shall have been issued and delivered to such person. As a condition of any transfer of the certificate for Shares, the Committee may obtain such agreements or undertakings, if any, as it may deem necessary or advisable to assure compliance with any provision of this Plan, any Option Agreement or any law or regulation including, but not limited to, the following:

(i)

a representation, warranty or agreement by the Optionee to the Company, at the time any Option is exercised, that he or she is acquiring the Shares to be issued to him or her for investment and not with a view to, or for sale in connection with, the distribution of any such Shares; and

(ii)

a representation, warranty or agreement to be bound by any legends that are, in the opinion of the Committee, necessary or appropriate to comply with the provisions of any securities law deemed by the Committee to be applicable to the issuance of the Shares and are endorsed upon the Share certificates.

11.

Amendment, Modification, Suspension or Discontinuance of this Plan. The Board of Directors may amend, modify, suspend or terminate the Plan for the purpose of meeting or addressing any changes in legal requirements or for any other purpose permitted by law. Subject to changes in law or other legal requirements, including any change in the provisions of Rule 16b-3 and Section 162(m) of the Code that would permit otherwise, the Plan may not be amended without the consent of the holders of a majority of the Shares of stock represented at a meeting of Shareholders for which a quorum is present, to (i) increase materially the aggregate number of Shares of stock that may be issued under the Plan (except for adjustments pursuant to paragraph 8 of the Plan), (ii) increase materially the benefit accruing to Optionees under the Plan, or (iii) modify materially the requirements as to eligibility for participation in the Plan.

12.

(a)

If any provision of this Plan is held to be invalid for any reason, such holding shall not affect the remaining provisions hereof, but instead this Plan shall be construed and enforced as if such provision had never been included in this Plan.

(b)

THIS PLAN SHALL BE GOVERNED BY THE LAWS OF THE STATE OF TEXAS.

(c)

Headings contained in this Plan are for convenience only and shall in no manner be construed as part of this Plan.

Any reference to the masculine, feminine, or neuter gender shall be a reference to such other gender as is appropriate.

13.

Section 83(b) Election. If as a result of exercising an Option, an Optionee receives Shares that are subject to a “substantial risk of forfeiture” and are not “transferable” as those terms are defined for purposes of Section 83(a) of the Code, then such Optionee may elect under Section 83(b) of the Code to include in his gross income, for his taxable year in which the Shares are transferred to him, the excess of the Fair Market Value of such Shares at the time of transfer (determined without regard to any restriction other than one which by its terms will never lapse), over the amount paid for the Shares. If the Optionee makes the Section 83(b) election described above, the Optionee shall (i) make such election in a manner that is satisfactory to the Committee, (ii) provide the Company with a copy of such election, (iii) agree to promptly notify the Company if any Internal Revenue Service or state tax agent, on audit or otherwise, questions the validity or correctness of such election or of the amount of income reportable on account of such election, and (iv) agree to such withholding as the Committee may reasonably require in its sole and absolute discretion.

14.
