Article 2.02-1.E provides that if a director is found liable to the corporation or is found liable on the basis that he or she improperly received a personal benefit, the permissible indemnification (1) is limited to reasonable expenses actually incurred by the person in connection with the proceeding, and (2) shall not be made in respect of any proceeding in which the person shall have been found liable for willful or intentional misconduct in the performance of his or her duty to the corporation. Finally, Article 2.02-1.H provides that a corporation shall indemnify a director against reasonable expenses incurred by him or her in connection with a proceeding in which he or she is a named defendant or respondent because he or she is or was a director if he or she has been wholly successful, on the merits or otherwise, in defense of the proceeding.</font></div><div style="text-align:justify"><font><br></font></div><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">With respect to the officers of a corporation, Article 2.02-1.O of the TBCA provides that a corporation may indemnify and advance expenses to an officer of the corporation to the same extent that it may indemnify and advance expenses to directors under Article 2.02-1.

Item 6.
Indemnification of Directors and Officers.
Article 2.02-1.B of the Texas Business Corporation Act, as amended (the "TBCA"), grants to a corporation the power to 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 against judgments, penalties (including excise and similar taxes), fines, settlements and reasonable expenses actually incurred in connection therewith, only if it is determined that the person (1) conducted him or herself in good faith; (2) reasonably believed that (a) in the case of conduct in his or her official capacity as a director of the corporation, his or her conduct was in the corporation's best interests, and (b) in all other cases, his or her conduct was at least not opposed to the corporation's best interests; and (3) in the case of any criminal proceeding, he or she had no reasonable cause to believe that his or her conduct was unlawful. Article 2.02-1.C limits the allowable indemnification by providing that, except to the extent permitted by Article 2.02-1.E, a director may not be indemnified in respect of a proceeding in which the person is found liable (1) on the basis that he or she improperly received a personal benefit, whether or not the benefit resulted from an action taken in his or her official capacity, or (2) to the corporation. Article 2.02-1.E provides that if a director is found liable to the corporation or is found liable on the basis that he or she improperly received a personal benefit, the permissible indemnification (1) is limited to reasonable expenses actually incurred by the person in connection with the proceeding, and (2) shall not be made in respect of any proceeding in which the person shall have been found liable for willful or intentional misconduct in the performance of his or her duty to the corporation. Finally, Article 2.02-1.H provides that a corporation shall indemnify a director against reasonable expenses incurred by him or her in connection with a proceeding in which he or she is a named defendant or respondent because he or she is or was a director if he or she has been wholly successful, on the merits or otherwise, in defense of the proceeding.
With respect to the officers of a corporation, Article 2.02-1.O of the TBCA provides that a corporation may indemnify and advance expenses to an officer of the corporation to the same extent that it may indemnify and advance expenses to directors under Article 2.02-1. Further, Article 2.02-1.O provides that an officer of a corporation shall be indemnified as, and to the same extent, provided by Article 2.02-1.H for a director.
The Company's Amended and Restated Bylaws, as amended provide that the Company shall indemnify a person against expenses actually and necessarily incurred by him or her in connection with the defense of any action, suit, or proceeding in which he or she is made a party because the person is or was a director or officer of the Company, except in relation to matters as to which he or she is adjudged to be liable for negligence or misconduct in performance of duty.
Officers and directors of the Company are presently covered by insurance which (with certain exceptions and within certain limitations) indemnifies them against any losses or liabilities arising from his or her status as a director or officer. The cost of such insurance is borne by the Company as permitted by the laws of the State of Texas.

Item 9.
Undertakings.
(a) The Company hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;
(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Filing Fee Tables" or "Calculation of Registration Fee" table, as applicable, in the effective registration statement; and
(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
Provided, however
, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if the registration statement is on Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Company pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.
(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial
bona fide
offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(b) The undersigned Company hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Company's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial
bona fide
offering thereof.
(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, the Company has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
