Unless otherwise provided in the Certificate of Formation, once a quorum is present at a duly constituted meeting of shareholders, the shareholders present or represented at the meeting may conduct such business as may be properly brought before the meeting until it is adjourned, and the subsequent withdrawal from the meeting of any shareholder present or represented shall not affect the presence of a quorum at the meeting. Unless otherwise provided in the Certificate of Formation, the shareholders entitled to vote and present or represented at a meeting of shareholders at which a quorum is not present may adjourn the meeting until such time and to such place as may be determined by a vote of the holders of a majority of the shares represented at that meeting. At such adjourned meeting at which a quorum shall be present or represented, any business may be conducted which might have been conducted at the meeting as originally notified.

Section 2.8 Voting: With respect to any matter, other than the election of directors or a matter for which the affirmative vote of the holders of a specified portion of the shares is required by the Certificate of Formation or applicable law, the affirmative vote of the holders of a majority of the combined voting power of the shares entitled to vote on that matter and represented at a meeting of shareholders at which a quorum is present shall be the act of the shareholders. Unless otherwise provided in the Certificate of Formation, directors shall be elected by a plurality of the votes cast by the holders of shares entitled to vote in the election of directors at a meeting of shareholders at which a quorum is present.

Section 2.9 Method of Voting: Each outstanding share shall be entitled to one vote on each matter submitted to a vote at a meeting of shareholders, unless the Certificate of Formation provide for more or less than one vote per share or limit or deny voting rights to the holders of the shares of any class or series or as otherwise provided by applicable law. A shareholder may vote in person, by duly authorized representative in the case of a corporation or other legal entity or by proxy executed in writing by the shareholder or by his, her or its duly authorized attorney-in-fact. A telegram, telex, cablegram, or other form of electronic transmission, including telephonic transmission, by the shareholder, or a photographic, photostatic, facsimile, or similar reproduction of a writing executed by a shareholder will be treated as an execution in writing. Any electronic transmission must contain or be accompanied by information from which it can be determined that the transmission has been authorized by the shareholder. No proxy shall be valid after 11 months from the date of its execution unless otherwise provided in the proxy. Each proxy shall be revocable unless the proxy form conspicuously states that the proxy is irrevocable and the proxy is coupled with an interest. Each proxy shall be filed with the Secretary of the Corporation prior to the time of the meeting.

count, and report the results of ballots cast by any shareholders voting in person; and perform such other duties as may be required by the chairman of the meeting or the shareholders.

Section 2.11 Procedure:

(a) The Executive Chairman or the Chairman of the Board of Directors, or such other officer of the Corporation designated by the Board of Directors, will call meetings of the shareholders to order and will act as presiding officer at the meetings.

Notwithstanding the foregoing provisions of this Section 2.11(c), a shareholder must also comply with all applicable requirements of the Exchange Act, and the rules and regulations thereunder with respect to the matters set forth in this Section 2.11(c). For purposes of this Section 2.11(c), “public announcement” means disclosure in a press release reported by a national news service or in a document filed by the Corporation with the Securities and Exchange Commission pursuant to Sections 13, 14 or 15(d) of the Exchange Act or furnished to shareholders. Nothing in this Section 2.11(c) will be deemed to affect any rights of shareholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act.

(d) A shareholder who wishes to nominate a director or directors for election at an annual meeting must comply with this Section 2.11(d). A shareholder who wishes to include business in a proxy statement prepared by the Corporation must also comply with Rule 14a-8 under the Exchange Act.

later of 70 calendar days prior to the date of the annual meeting or the close of business on the 7th calendar day following the earlier of the date on which notice of the annual meeting is first mailed by or on behalf of the Corporation or the day on which public announcement is first made of the date of the annual meeting. To be timely in connection with a special meeting, a shareholder’s notice must be delivered to or mailed and received at the principal executive offices of the Corporation not less than 40 calendar days nor more than 60 calendar days prior to the date of such meeting; provided, however, that in the event that less than 50 calendar days’ notice or prior public announcement of the date of the special meeting is given or made to the shareholders, the shareholder’s notice to be timely must be so received not later than the close of business on the 7th calendar day following the earlier of the date on which notice of the date of the special meeting was first mailed by or on behalf of the Corporation or the day on which public announcement is first made of the date of the special meeting. In no event shall any adjournment or postponement of an annual or special meeting or the announcement thereof commence a new time period for the giving of the notice required by this Section 2.11(d).

A shareholder’s notice to the Secretary must set forth: (A) as to each person whom the shareholder proposes to nominate for election or reelection as a director all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act, including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director, if elected; (B) as to the shareholder giving the notice the name and address, as they appear on the Corporation’s books, of such shareholder and any Shareholder Associated Person covered by clause (C) below; (C) as to the shareholder giving the notice the class and number of shares of the Corporation that are owned beneficially and of record by such shareholder and by any Shareholder Associated Person with respect to the Corporation’s securities, and any derivatives, hedged positions, synthetic and temporary ownership techniques, swaps, securities loans, timed purchases and other economic and voting interests or similar positions, securities or interests held by such shareholder and Shareholder Associated Person with respect to the Corporation’s securities; (D) a description of any material relationships, including financial transactions and compensation, between the shareholder giving the notice and any Shareholder Associated Person, on the one hand, and the proposed nominee or nominees, on the other; (E) a completed independence questionnaire regarding the proposed nominee or nominees, which may be obtained from the Secretary of the Corporation; and (F) a written representation from such proposed nominee or nominees that they do not

At the request of the Board of Directors, any person nominated by the Board of Directors for election as a director shall furnish to the Secretary that information required to be set forth in a shareholder’s notice of nomination which pertains to the nominee.

Notwithstanding the foregoing provisions of this Section 2.11(d), a shareholder must also comply with all applicable requirements of the Exchange Act, and the rules and regulations thereunder with respect to the matters set forth in this Section 2.11(d).

ARTICLE III

DIRECTORS

Section 3.1 Responsibilities: The powers of the Corporation shall be exercised by or under the authority of, and the business and affairs of the Corporation shall be managed under the direction of, its Board of Directors.

Section 3.2 Number; Election; Qualification; Term: The number of directors shall be fixed from time to time by the Board of Directors; provided, however, that no decrease in the number of directors shall have the effect of shortening the term of any incumbent director. The directors shall be elected at the annual meeting of the shareholders, as provided in this Section 3.2, except as otherwise provided in Section 3.3. Each director shall hold office until the next annual meeting of shareholders or until his successor shall have been elected and qualified. Unless removed in accordance with the Certificate of Formation or Section 3.4, each director elected shall hold office for the term for which he or she is elected and until his or her successor shall have been elected and qualified or until his or her earlier death, retirement, resignation or removal for cause in accordance with the provisions of these Bylaws. Directors need not be residents of the State of Texas or shareholders of the Corporation, but they must have been nominated in accordance with the procedures set forth in these Bylaws in order to be eligible for election as directors.

Section 3.3 Vacancies; Increases: Any vacancy occurring in the Board of Directors (by death, retirement, resignation, removal or otherwise) may be filled by election at an annual or special meeting of shareholders called for that purpose, or by the affirmative vote of a majority of the remaining directors then in office, though less than a quorum. Each director elected to fill a vacancy shall be elected for the unexpired term of his or her predecessor in office. Any directorship to be filled by reason of an increase in the number of directors may be filled by election at an annual or special meeting of shareholders called for that purpose or by the Board of Directors for a term of office continuing only until the next election of one or more directors by the shareholders; provided, however, that the Board of Directors may not fill more than two such directorships during the period between any two successive annual meetings of shareholders.

Section 3.8 Purpose of Meetings: Neither the purpose of, nor the business to be transacted at, any regular or special meeting of the Board of Directors need be specified in the notice or waiver of notice of such meeting.

Section 3.9 Quorum; Majority Vote: At all meetings of the Board of Directors, a majority of the number of the directors fixed in the manner provided in these Bylaws shall constitute a quorum for the transaction of business unless a different number is specifically required by the Certificate of Formation, these Bylaws or applicable law. The act of a majority of the directors present at a meeting at which a quorum is present shall be the act of the Board of Directors, unless the act of a greater number is required by the Certificate of Formation, these Bylaws or applicable law. If a quorum shall not be present at any meeting of the Board of Directors, the directors present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present.

Section 3.10 Procedure: At meetings of the Board of Directors, business shall be transacted in such order as the Board of Directors may determine from time to time. The Executive Chairman or Chairman of the Board, if one of such offices has been filled, and, if not or if the then sitting Executive Chairman or

Chairman of the Board is absent or otherwise unable to act, a chairman chosen by the Board of Directors from among the directors present, will preside over the meetings of the Board. The Secretary of the Corporation shall act as the secretary of the meetings of the Board of Directors unless the Board of Directors appoints another person to act as secretary of the meeting. The Board of Directors shall keep regular minutes of its proceedings which shall be placed in the minute book of the Corporation.

Section 3.11 Presumption of Assent: A director of the Corporation who is present at a meeting of the Board of Directors at which action on any corporate matter is taken shall be presumed to have assented to the action unless his or her dissent shall be entered in the minutes of the meeting or unless he or she shall file a written dissent to such action with the person acting as secretary of the meeting before the adjournment thereof or shall forward any dissent by certified or registered mail to the Secretary of the Corporation immediately after the adjournment of the meeting. Such right to dissent shall not apply to a director who voted in favor of such action.

Section 3.12 Compensation: The Board of Directors shall have authority to fix the compensation, including fees and reimbursement of expenses, paid to directors for attendance at regular or special meetings of the Board of Directors, any committee thereof or for any other services to the Corporation; provided, however, that nothing contained in these Bylaws shall be construed to preclude any director from serving the Corporation in any other capacity or receiving compensation therefor.

Section 3.13 Committees: The Board of Directors, by resolution adopted by a majority of the full Board of Directors, may designate from among its members one or more committees, each of which shall be comprised of one or more members, and may designate one or more of its members as alternate members of any committee, who may, subject to any limitations imposed by the Board of Directors, replace absent or disqualified members at any meeting of that committee. Any such committee, to the extent provided in such resolution or in the Certificate of Formation or these Bylaws, shall have and may exercise all of the authority of the Board of Directors, except as otherwise provided by applicable law. The designation of such committee and the delegation thereto of authority shall not operate to relieve the Board of Directors, or any member thereof, of any responsibility imposed by applicable law. Such committee or committees shall have such name or names as may be determined from time to time by resolution adopted by the Board of Directors.

Section 3.14 Committee Procedures: Except as may be otherwise provided in a resolution or resolutions adopted by the Board of Directors, a majority of the members of a committee shall constitute a quorum and a majority vote of the members at a meeting at which a quorum is present shall be the act of the committee. A committee shall keep minutes of its proceedings, and shall report its proceedings to the Board of Directors when required or when requested by a director to do so.

Section 3.15 Action Without Meeting: Unless otherwise restricted by the Certificate of Formation or these Bylaws, any action required or permitted to be taken at a meeting of the Board of Directors or any committee may be taken without a meeting if a consent in writing, setting forth the action so taken, is signed by all the members of the Board of Directors or committee, as the case may be. Such consent shall have the same force and effect as a unanimous vote at a meeting.

Section 3.16 Executive Chairman; Chairman of the Board: The Board of Directors may annually elect one of its members to be Executive Chairman of the Board (the “Executive Chairman”) and may fill any vacancy in the position of Executive Chairman of the Board with a director at such time and in such manner as the Board of Directors shall determine. The Executive Chairman shall not be an officer, executive or employee of the Corporation by virtue of such position and shall have the same rights, duties and obligations to the Corporation and its shareholders as other members of the Board of Directors who are not officers, executives or employees of the Corporation and shall not have any additional or heightened rights, duties or obligations by virtue of such position. A director may be removed from the position of Executive Chairman at any time by the affirmative vote of the Board of Directors whenever in its judgment the best interests of the Corporation will be served thereby, but such removal shall be without prejudice to the contract rights, if any, of the person so removed and shall not affect the person’s position as a director. Neither the Corporation nor the Board shall elect a Chairman of the Board while there is an Executive Chairman in office. For the avoidance of doubt, (a) the Chairman of the Board may be, but is not required to be, an officer, executive or employee of the Corporation and (b) unless specifically elected as the “Executive Chairman,” an officer, executive or employee of the Corporation may hold the position of Chairman of the Board without holding the position of Executive Chairman.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 6.1 Indemnification: Each person who 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 corporation, employee benefit plan, other enterprise or other entity shall be indemnified by the Corporation to the fullest extent that a corporation is required or permitted to grant indemnification to such person under the Texas Business Organizations Code, as the same exist or may hereafter be amended. Reasonable expenses incurred by a director or officer of the Corporation 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, to the maximum extent permitted under the Texas Business Organizations Code, as the same exists or may hereafter be amended. Such advancement rights pertain to expenses incurred in connection with all proceedings for which indemnification is provided. The right to advancement of expenses and indemnification under this Article VI shall be a contract right between the Corporation and each director or officer who serves in such a capacity at any time while such provisions are in effect, whether or not such person continues to serve in such capacity at the time advancement or indemnification is sought. Indemnification and advancement provisions cannot be retroactively amended to

adversely affect the rights of indemnified persons arising in connection with any acts, omissions, facts or circumstances occurring prior to such amendment. In the event of the death of any person having a right of indemnification under this Article VI, such right will inure to the benefit of his or her heirs, executors, administrators and personal representatives. The rights under this Article VI will not be exclusive of any other right which any person may have or hereinafter acquire under any bylaw, resolution of shareholders or directors, agreement, applicable law or otherwise.

SHARES OF CAPITAL STOCK

Section 7.1 Certificates: Shares of the capital stock of the Corporation may be certificated or uncertificated, as provided under the Texas Business Organizations Code. Certificates for shares of stock of the Corporation shall be in such form as shall be approved by the Board of Directors. The certificates shall be signed by the Executive Chairman, Chairman of the Board, the Chief Executive Officer, the President or a Vice President and also by the Secretary or an Assistant Secretary or the Treasurer or an Assistant Treasurer. Any and all signatures on the certificate may be a facsimile and each such certificate may be sealed with the seal of the Corporation or a facsimile thereof. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon a certificate has ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the Corporation with the same effect as if he or she were such officer, transfer agent or registrar at the date of issue. The 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 the number of shares. The Corporation shall, after the issuance or transfer of uncertificated shares, send to the registered owner of uncertificated shares a written notice containing the information required to be set forth or stated on certificates pursuant to the Texas Business Organizations Code.

Section 7.2 Lost, Stolen or Destroyed Certificates: The Board of Directors may direct (i) a new certificate or certificates representing shares of stock or (ii) uncertificated shares be issued in place of a certificate or certificates representing shares of stock theretofore issued by the Corporation and alleged to have been lost or destroyed upon the making of an affidavit of that fact by the person claiming the certificate or certificates representing shares of stock that was or were lost or destroyed. When authorizing such issue of a new certificate or certificates or uncertificated shares, the Board of Directors may in its discretion

and as a condition precedent to the issuance thereof, require the owner of such lost or destroyed certificate or certificates, or his or her legal representative, to advertise the same in such manner as it shall require and/or to give the Corporation a bond with a surety or sureties satisfactory to the Corporation in such sum as it may direct as indemnity against any claim or expense resulting from a claim that may be made against the Corporation with respect to the certificate or certificates alleged to have been lost or destroyed.

Section 7.3 Transfer of Shares: Shares of stock, whether certificated or uncertificated, shall be transferable only on the books of the Corporation by the holders thereof or by their duly authorized attorneys or legal representatives. 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, the Corporation or its transfer agent shall issue a new certificate or evidence of the issuance of uncertificated shares to the person entitled thereto, cancel the old certificate and record the transaction upon its books. Upon the receipt of proper transfer instructions from the registered owner of uncertificated shares, such uncertificated shares shall be cancelled, issuance of new equivalent uncertificated shares or certificated shares shall be made to the shareholder entitled thereto and the transaction shall be recorded upon the Corporation’s books. If the Corporation has a transfer agent or registrar acting on its behalf, the signature of any officer or representative thereof may be in facsimile.

Section 7.4 Registered Shareholders: The Corporation shall be entitled to treat the holder of record of any share or shares of stock, whether such shares are evidenced by a certificate or are uncertificated, as the holder in fact thereof and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person, whether or not it shall have express or other notice thereof, except as otherwise provided by applicable law.

Section 7.5 Regulations: The Board of Directors may appoint a transfer agent and one or more co-transfer agents and registrar and one or more co-registrars and may make or authorize such agent to make all such rules and regulations deemed expedient concerning the issue, transfer and registration of shares of stock.

Section 7.6 Legends: The Board of Directors shall have the power and authority to provide that the certificates representing shares of stock of the

Corporation bear such legends as the Board of Directors deems appropriate to assure that the Corporation does not become liable for violations of federal or state securities laws or other applicable law.
