Subject to the limitations and conditions as provided in this Article VI, and in Section 2.02-1 of the TBCA (relating among other matters to liability for receipt of an improper personal benefit or liability to the Corporation), as from time to time amended, each person who was or is made a party or is threatened to be made a party to or is involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, arbitrative or investigative (hereinafter a "proceeding"), or any appeal in such a proceeding or any inquiry or investigation that could lead to such a proceeding, by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director or officer of the Corporation or while a director or officer 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 shall be indemnified by the Corporation to the fullest extent permitted by the TBCA as the same exists or may hereafter be amended against judgments, penalties (including excise and similar taxes and punitive damages), fines, settlements and reasonable expenses (including, without limitation, attorneys' fees) actually incurred by such person in connection with such proceeding, and indemnification under this Article VI shall continue as to a person who has ceased to serve in the capacity which initially entitled such person to indemnity hereunder. The rights granted pursuant to this Article VI shall be deemed contract rights, and no amendment, modification or repeal of this Article VI shall have the effect of limiting or denying any such rights with respect to actions taken or proceedings arising prior to any such amendment, modification or repeal. It is expressly acknowledged that the indemnification provided in this Article VI could involve indemnification for negligence or under theories of strict liability. SECTION 2. ADVANCE PAYMENT. The right to indemnification conferred in this Article VI shall include the right to be paid or reimbursed by the Corporation the reasonable expenses incurred by a person of the type entitled to be indemnified under Section 1 who was, is or is threatened to be made a named defendant or respondent in a proceeding in advance of the final disposition of the proceeding and without any determination as to the person's ultimate entitlement to indemnification; provided, however, that the payment of such expenses incurred by any such person in advance of the final disposition of a proceeding, shall be made only upon delivery to the Corporation of a written affirmation by such director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification under this Article VI and a written undertaking, by or on behalf of such person, to repay all amounts so advanced if it shall ultimately be determined that such indemnified person is not entitled to be indemnified under this Article VI or otherwise. SECTION 3. INDEMNIFICATION OF EMPLOYEES AND AGENTS. The Corporation, by adoption of a resolution of the Board of Directors, may (but shall not be required to) indemnify and advance expenses to an employee or agent of the Corporation to the same extent and subject to the same conditions under which it may indemnify and advance expenses to 12

directors and officers under this Article VI; and, the Corporation may (but shall not be required to) indemnify and advance expenses to persons who are not or were not directors, officers, employees or agents of the Corporation but 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 venture, sole proprietorship, trust, employee benefit plan and or other enterprise against any liability asserted against that person and incurred by that person in such a capacity or arising out of such individual's status as such a person to the same extent that it may indemnify and advance expenses to directors under this Article VI. SECTION 4. APPEARANCE AS A WITNESS. Notwithstanding any other provision of this Article VI, the Corporation may pay or reimburse expenses incurred by a director or officer in connection with his or her appearance as a witness or other participation in a proceeding at a time when he or she is not a named defendant or respondent in the proceeding. SECTION 5. NONEXCLUSIVITY OF RIGHTS. The right to indemnification and the advancement and payment of expenses conferred in this Article VI shall not be exclusive of any other right which a director or officer or other person indemnified pursuant to Section 3 of this Article VI may have or hereafter acquire under any law (common or statutory), provision of the Amended and Restated Articles of Incorporation or these bylaws, agreement, vote of shareholders or disinterested directors or otherwise. SECTION 6. INSURANCE. The Corporation may purchase and maintain insurance and, to the extent permitted by the TBCA, similar arrangements, at its expense, to protect itself and any person who is or was serving as a director, officer, employee or agent of the Corporation or 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, proprietorship, employee benefit plan, trust or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under this Article VI. SECTION 7. SHAREHOLDER NOTIFICATION. To the extent required by law, any indemnification of or advance of expenses to a director or officer in accordance with this Article VI shall be reported in writing to the shareholders with or before the notice or waiver of notice of the next shareholder's meeting or with or before the next submission to shareholders of a consent to action without a meeting. SECTION 8. SAVINGS CLAUSE. If this Article VI or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify and hold harmless each director, officer or any other person indemnified pursuant to this Article VI as to costs, charges and expenses (including attorneys' fees), judgments, fines and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative to the full extent permitted by any applicable portion of this Article VI that shall not have been invalidated and to the fullest extent permitted by applicable law. 13

ARTICLE VII CAPITAL STOCK SECTION 1. CERTIFICATES OF STOCK. The certificates for shares of the capital stock of the Corporation shall be in such form, consistent with that required by law and the Amended and Restated Articles of Incorporation, as shall be approved by the Board of Directors. The Chairman of the Board, President or a Vice President (if any) shall cause to be issued to each shareholder one or more certificates, which shall be signed by (a) one of the chief executive officer, President, or a Vice President and (b) one of the Chief Financial Officer, Secretary, an Assistant Secretary, the Treasurer or an Assistant Treasurer certifying the number of shares (and, if the stock of the Corporation shall be divided into classes or series, the class and series of such shares) owned by such shareholder in the Corporation; provided however, that any or all of the signatures on the certificate may be facsimile. If the Board of Directors shall have provided for a seal, such certificates shall bear such seal or a facsimile thereof. The stock record books and the blank stock certificate books shall be kept by the Secretary, or at the office of such transfer agent or transfer agents as the Board of Directors may from time to time by resolution determine. In case any officer, transfer agent or registrar who shall have signed or have ceased to be such officer, transfer agent or registrar before such certificate is issued by the Corporation, such certificate may nevertheless be issued by the Corporation with the same effect as if such person were such officer, transfer agent or registrar at the date of issue. The stock certificates shall be consecutively numbered and shall be entered in the books of the Corporation as they are issued and shall exhibit the holder's name and number of shares. SECTION 2. TRANSFER OF SHARES. The shares of stock of the Corporation shall be transferable only on the books of the Corporation by the holders thereof in person or by their duly authorized attorneys or legal representatives, upon surrender and cancellation of certificates for a like number of shares (or upon compliance with the provisions of Section 4 of this Article VII, if applicable). Upon such surrender to the Corporation or a transfer agent of the Corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignment or authority to transfer (or upon compliance with the provisions of Section 4 of this Article VII, if applicable) and of compliance with any transfer restrictions applicable thereto contained in an agreement to which the Corporation is a party or of which the Corporation has knowledge by reason of legend with respect thereto placed on any such surrendered stock certificate, it shall be the duty of the Corporation to issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books. SECTION 3. REGULATIONS REGARDING CERTIFICATES. The Board of Directors shall have the power and authority to make all such rules and regulations as they may deem expedient concerning the issuance, transfer and registration or the replacement of certificates for shares of capital stock of the Corporation. SECTION 4. LOST, STOLEN, DESTROYED OR MUTILATED CERTIFICATES. The Board of Directors may determine the conditions upon which a new certificate of stock may be issued in place of a certificate that is alleged to have been lost, stolen, destroyed or mutilated; and may, in its discretion, require the owner of such certificate or his legal representative to give bond, with sufficient surety, to indemnify the Corporation and each transfer agent and registrar 14

against any and all losses or claims which may arise by reason of the issuance of a new certificate in the place of the one so lost, stolen, destroyed or mutilated. ARTICLE VIII MISCELLANEOUS PROVISIONS SECTION 1. FISCAL YEAR. The fiscal year of the Corporation shall be such as established from time to time by the Board of Directors. SECTION 2. CORPORATE SEAL. The Board of Directors may provide a suitable seal, containing the name of the Corporation. The Secretary shall have charge of the seal (if any). If and when so directed by the Board of Directors, duplicates of the seal may be kept and used by the Treasurer, if any, or by any Assistant Secretary or Assistant Treasurer. SECTION 3. NOTICE AND WAIVER OF NOTICE. Whenever any notice is required to be given by law, the Amended and Restated Articles of Incorporation or these bylaws, except with respect to notices of meetings of shareholders (with respect to which the provisions of Article II, Section 6 apply) and except with respect to notices of special meetings of the Board of Directors (with respect to which the provisions of Article III, Section 6 apply), said notice shall be deemed to be sufficient if given (a) by telegraphic, cable, telecopy, facsimile, electronic mail, or wireless transmission or (b) by deposit of same in a post office box in a sealed prepaid wrapper addressed to the person entitled thereto at his or her address as it appears on the records of the Corporation, and such notice shall be deemed to have been given on the day of such transmission or mailing, as the case may be. Whenever notice is required to be given by law, the Amended and Restated Articles of Incorporation or these bylaws, a written waiver thereof, signed by the person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to the notice required to be given by law, the Amended and Restated Articles of Incorporation or these bylaws, as the case may be. SECTION 4. RESIGNATIONS. Any director, member of a committee or officer may resign at any time. Such resignation shall be made in writing and shall take effect at the time specified therein, or if no time be specified, at the time of its receipt by the chief executive officer or Secretary. The acceptance of a resignation shall not be necessary to make it effective, unless expressly so provided in the resignation. SECTION 5. FACSIMILE SIGNATURES. In addition to the provisions for the use of facsimile signatures elsewhere specifically authorized in these bylaws, facsimile signatures of any officer or officers of the Corporation may be used whenever and as authorized by the Board of Directors. SECTION 6. BOOKS AND RECORDS. The Corporation shall keep books and records of account and shall keep minutes of the proceedings of its shareholders, its Board of Directors and each committee of its Board of Directors. The Corporation shall keep at its registered office or principal place of business, or at the office of its transfer agent or registrar, a record of the 15

original issuance of shares issued by the Corporation and a record of each transfer of those shares that have been presented to the Corporation for registration of transfer. Such records shall contain the names and addresses of all past and current shareholders of the Corporation and the number and class of shares issued by the Corporation held by each of them. Any books, records, minutes and share transfer records may be in written form or in any other form capable of being converted into written form within a reasonable time. SECTION 7. AMENDMENT OF BYLAWS. No provision of the Corporation's bylaws which has been adopted by the shareholders may be amended, modified or repealed, except by the vote of a majority of the shareholders. No bylaw provision which conflicts with or is contrary to a bylaw adopted by the shareholders may be adopted, except by the vote of a majority of the shareholders. Except as otherwise provided in this Section 7, the power to alter, amend or repeal the bylaws or adopt new bylaws shall be vested in the Board of Directors. 16
