(2) “Director” means any person who is or was a director of the corporation and any person who, while a director of the corporation, is or was serving at the request of the corporation as a director, officer, partner, venturer, proprietor, trustee, employee, agent, or similar functionary of another foreign or domestic corporation, partnership, joint venture, sole proprietorship, trust, employee benefit plan, or other enterprise.

B. The corporation shall indemnify a person who was, is, or is threatened to be made a named defendant or respondent in a proceeding because the person is or was a director of the corporation only if it is determined in accordance with Paragraph F that the person:

(1) conducted himself in good faith;

(2) reasonably believed:

(a) in the case of conduct in his official capacity as a director of the corporation, that his conduct was in the corporation’s best interest; and

(b) in all other cases, that his conduct was at least not opposed to the corporation’s best interests; and

(3) in the case of any criminal proceeding, had no reasonable cause to believe his conduct was unlawful.

C. A director may not be indemnified under Paragraph B for obligations resulting from a proceeding:

(1) in which the person is found liable on the basis that personal benefit was improperly received by him, whether or not the benefit resulted from an action taken in the person’s official capacity; or

(2) in which the person is found liable to the corporation.

-4-

D. The termination of a proceeding by judgment, order, settlement, or conviction, or on a plea of nolo contendere or its equivalent is not of itself determinative that the person did not meet the requirements set forth in Paragraph B.

E. A person shall be indemnified under Paragraph B against judgments, penalties (including excise and similar taxes), fines, settlements, and reasonable expenses actually incurred by the person in connection with the proceeding; but if the proceeding was brought by or in behalf of the corporation, the indemnification is limited to reasonable expenses actually incurred by the person in connection with the proceeding.

F. A determination of indemnification under Paragraph B must be made:

(1) by a majority vote of a quorum consisting of directors who at the time of the vote are not named defendants or respondents in the proceeding;

(2) if such a quorum cannot be obtained, by a majority vote of a committee of the board of directors, designated to act in the matter by a majority vote of all directors, consisting solely of two or more directors what at the time of the vote are not named defendants or respondents in the proceeding;

(3) by special legal counsel selected by the board of directors or a committee of the board by vote as set forth in Subparagraph (1) or (2) of this Paragraph F, or, if such a quorum cannot be obtained and such a committee cannot be established, by a majority vote of all directors; or

(4) by the shareholders in a vote that excludes the shares held by directors who are named defendants or respondents in the proceeding.

G. Authorization of indemnification and determination as to reasonableness of expenses must be made in the same manner as the determination that indemnification is

-5-

permissible, except that if determination that indemnification is permissible is made by special legal counsel, authorization of indemnification and determination as to reasonableness of expenses must be made in the manner specified by Subparagraph (3) of Paragraph F for the selection of special legal counsel.

H. Notwithstanding any other provision of this Article 10, the corporation shall indemnify a director against reasonable expenses incurred by him in connection with a proceeding in which he is a party because he is a director if he has been wholly successful, on the merits or otherwise, in the defense of the proceeding.

I. If in a suit for the indemnification required by Paragraph H, a court of competent jurisdiction determines that the director is entitled to indemnification under Paragraph H, the court shall order indemnification and shall award to the director the expenses incurred in securing the indemnification.

J. If, a court of competent jurisdiction determines that a director is fairly and reasonably entitled to indemnification in view of all the relevant circumstances, whether or not he has met the requirements set forth in Paragraph B or has been adjudged liable in the circumstances described by Paragraph C, the court may order the indemnification that the court determines is proper and equitable. The court shall limit indemnification to reasonable expenses if the proceeding is brought by or in behalf of the corporation if the director is found liable on the basis that personal benefit was improperly received by him, whether or not the benefit resulted from an action taken in the person’s official capacity.

-6-

K. Reasonable expenses incurred by a director who was, is, or is threatened to be made a named defendant or respondent in a proceeding shall be paid or reimbursed by the corporation in advance of the final disposition of the proceeding after:

(1) the corporation receives a written affirmation by the director of his good faith belief that he has met the standard of conduct necessary for indemnification under this Article 10 and a written undertaking by or on behalf of the director to repay the amount paid or reimbursed if it is ultimately determined that he has not met those requirements; and

(2) a determination that the facts then known to those making the determination would not preclude indemnification under this Article 10.

L. The written undertaking required by Paragraph K must be an unlimited general obligation of the director but need not be secured. It may be accepted without reference to financial ability to make repayment. Determinations and authorizations of payments under Paragraph K must be made in the manner specified by Paragraph F for determining that indemnification is permissible.

M. Notwithstanding any other provision of this Article 10, the corporation may pay or reimburse expenses incurred by a director in connection with his appearance as a witness or other participation in a proceeding at a time when he is not a named defendant or respondent in the proceeding.

N. The corporation shall indemnify and advance expenses to an officer, employee or agent of the corporation to the same extent that it shall indemnify and advance expenses to directors under this Article 10.

O. The corporation shall indemnify and advance expenses to nominees or designees who are not or were not officers, employees, or agents of the corporation who are or were serving at the request of the corporation as a director, officer, partner, venturer, proprietor, trustee, employee, agent, or similar functionary of another foreign or domestic corporation,

-7-

partnership, joint venture, sole proprietorship, trust, other enterprise, or employee benefit plan to the same extent that it shall indemnify and advance expenses to directors under this Article 10.

P. Notwithstanding any other provision of this Article 10, the corporation shall indemnify and advance expenses to an officer, employee, agent, or person who is identified by Paragraph O as a nominee or designee and who is not a director, to such further extent as such person may be entitled by law, agreement, vote of shareholders, or otherwise.

Q. The corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, or agent of the corporation or who is or was serving at the request of the corporation as a director, officer, partner, venturer, proprietor, trustee, employee, agent, or similar functionary of another foreign or domestic corporation, partnership, joint venture, sole proprietorship, trust, other enterprise, or employee benefit plan, against any liability asserted against him and incurred by him in such a capacity or arising out of his status as such a person, whether or not the corporation would have the power to indemnify him against that liability under this Article 10.

R. Any indemnification of or advance of expenses to a director in accordance with this Article 10 shall be reported in writing to the shareholders with or before the notice or waiver of notice of the next shareholders’ meeting or with or before the next submission to shareholders of a consent to action without a meeting pursuant to Article 9.10 A of the Texas Business Corporation Act and, in any case, within the twelve (12) month period immediately following the date of the indemnification or advance.

S. For purposes of this Article 10 the corporation is deemed to have requested a director to serve an employee benefit plan whenever the performance by him of his duties to the corporation also imposes duties on or otherwise involves services by him to the plan or

-8-

participants or beneficiaries of the plan. Excise taxes assessed on a director with respect to an employee benefit plan pursuant to applicable law are deemed fines. Action taken or omitted by him with respect to an employee benefit plan in the performance of his duties for a purpose reasonable believed by him to be in the interest of the participants and beneficiaries of the plan is deemed to be for a purpose which is not opposed to the best interests of the corporation.
