The Corporation may 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 Section 6 of this Article XI that the person: (a) conducted himself in good faith; (b) reasonably believed: (1) in the case of conduct in his official capacity as a director of the Corporation, that his conduct was in the Corporation's best interests; and (2) in all other cases, that his conduct was at least not opposed to the Corporation's best interests; and (c) in the case of any criminal proceeding, had no reasonable cause to believe his conduct was unlawful.

Section 4. The termination of a proceeding by judgment, order, settlement, or conviction, or on a plea of nolo contenders or its equivalent is not of itself determinative that the person did not meet the requirements set forth in Section 2 of this Article.

Section 10. If, upon application of a director, a court of competent jurisdiction determines, after giving any notice the court considers necessary, that the 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 Section 2 of this Article XI or has been adjudged liable in the circumstances described by Section 3 of this Article XI, 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 or 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. Section 11. Reasonable expenses incurred by a director who was, is, or is threatened to be made a named defendant or respondent in a proceeding may be paid or reimbursed by the Corporation, in advance of the final disposition of the proceeding and without any of the determination specified in Section 6 and 7 of this Article XI, after 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 XI 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. Section 12. The written undertaking required by Section 11 of this Article XI 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. Section 13. A provision for the Corporation to indemnify or to advance expenses to a director who was, is, or is threatened to be made a named defendant or respondent in a proceeding, whether contained in the Articles of Incorporation, the Bylaws, a resolution of shareholders or directors, an agreement or otherwise, except in accordance with Section 18 of this Article XI, is valid only to the extent it is consistent with this Article XI as limited by the Articles of Incorporation, if such a limitation exists.

Section 15. An officer of the Corporation shall be indemnified as, and to the same extent, provided by Sections 8, 9, and 10 of this Article XI for a director and is entitled to seek indemnification under those sections to the same extent as a director. The Corporation may indemnify and advance expenses to an officer, employee, or agent of the Corporation to the same extent that it may indemnify and advance expenses to directors under this Article XI. Section 16. The Corporation may indemnify and advance expenses to persons 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, partnership, joint venturer sole proprietorship, trust, employee benefit plan or other enterprise, to the same extent that it may indemnify and advance expenses to directors under this Article XI. Section 17. The Corporation may indemnify and advance expenses to an officer, employee or agent, or person who is identified in Section 16 of this Article XI and who is not a director to such further extent, consistent with law, as may be provided by the Articles of Incorporation, Bylaws, general or specific action of the Board of Directors, or contract or as permitted or required by common law. Section 18. The Corporation may purchase and maintain insurance or another arrangement 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, employee benefit plan, or other enterprise, 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 XI. If the insurance or other arrangement is with a person or entity that is not regularly engaged in the business of providing insurance coverage, the insurance or arrangement may provide for payment of a liability with respect to which the Corporation would not have the power to indemnify the person only if including coverage for the additional liability has been approved by the shareholders of the Corporation. Without limiting the power of the Corporation to procure or maintain any kind of insurance or other arrangement, the Corporation may, for the benefit of persons indemnified by the Corporation: (a) create a trust fund; (b) establish any form of self-insurance; (c) secure its indemnity obligation by grant of a security interest or other lien on the assets of the Corporation; or (d) establish a letter of credit, guaranty, or surety arrangement. The insurance or other arrangement may be procured, maintained, or established within the Corporation or with any insurer or other person deemed appropriate by the Board of Directors regardless of whether all or part of the stock or other securities of the insurer `or other person are owned in whole or part by the Corporation. In the absence of fraud, the judgment of the Board of Directors as to the terms and conditions of the insurance or other arrangement and the identity of the insurer or other person participating in an arrangement shall be conclusive and the insurance or arrangement shall not be voidable and shall not subject the directors approving the insurance or arrangement to liability, on any ground, regardless of whether directors participating in the approval are beneficiaries of the insurance or arrangement. Section 19. Any indemnification of or advance of expenses to a director in accordance with this Article XI 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 the shareholders of a consent to action without a meeting pursuant to Section A, Article 9.10 of the Texas Business Corporation Act and, in any case, within the 12-month period immediately following the date of the indemnification or advance. Section 20. For purposes of this Article XI, 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 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 hisduties for a purpose reasonably 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.

LOST CERTIFICATES Section 3. The Board of Directors may direct a new certificate to be issued in place of any certificate theretofore issued by the Corporation alleged to have been lost or destroyed. When authorizing such issue of a new certificate, the Board of Directors, in its discretion and as a condition precedent to the issuance thereof, may prescribe such terms and conditions as it deems expedient, and may require such indemnities as it deems adequate, to protect the Corporation from any claim that may be made against it with respect to any such certificate alleged to have been lost or destroyed. TRANSFER OF SHARES Section 4. Upon surrender to the Corporation or the transfer agent of the Corporation of a certificate representing shares duly endorsed or accompanied by proper evidence of succession, assignment or authority to transfer, a new certificate shall be issued to the person entitled thereto, and the old certificate canceled and the transaction recorded upon the books of the Corporation.
