If the day selected is a legal holiday, then the meeting shall be held on the next business day following.

Special meetings of the shareholders for any purpose or purposes may be called by the President and shall be called by the President or Secretary at the request in writing of a majority of the Board of Directors, or at the request in writing of shareholders owning not less than 10% of all the shares entitled to vote at the meeting. A request for a special meeting shall state the purpose or purposes of

the proposed meeting, which purpose or purposes shall be stated in the notice of the meeting. Business transacted at any special meeting of shareholders shall be limited to the purposes stated in the notice of the special meeting.

The notice may be given in person, by any form of electronic transmission permitted under Texas law (upon the consent of the shareholder receiving such electronic transmission), or by mail. If mailed, such notice shall be deemed to be given on the date notice is deposited in the United States mail with postage paid in an envelope addressed to the shareholder at the shareholder’s address as it appears on the stock transfer records of the Corporation. If given by electronic transmission, such notice shall be deemed to be provided when the notice is (i) transmitted to a facsimile number provided by the shareholder for the purpose of receiving notice; (ii) transmitted to an electronic mail address provided by the shareholder for the purpose of receiving notice; (iii) posted on an electronic network and a message is sent to the shareholder at the address provided by the shareholder for the purpose of alerting the shareholder of a posting; or (iv) communicated to the shareholder by any other form of electronic transmission permitted under Texas law and consented to by the shareholder.

At any such reconvened meeting at which a quorum is present or represented, any business may be transacted which might have been transacted at the meeting as originally convened had a quorum been present. Shareholders present at a duly organized meeting with a quorum present may continue to do business properly brought before the meeting until adjournment of such meeting, notwithstanding the withdrawal of enough shareholders to leave less than a quorum.

2.06      Method of 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 entitled to vote is required by Texas law or the Certificate of Formation, the act of the shareholders with respect to a matter shall be the affirmative vote of the holders of a majority of the shares entitled to vote on, and voted for or against, or expressly abstained from voting with respect to, the matter at a meeting of shareholders at which a quorum is present. Each outstanding share, regardless of class, shall be entitled to one vote on each matter submitted to a vote at a meeting of shareholders, except to the extent that the voting rights of the shares of any class or classes are limited or denied by the Certificate of Formation, or as otherwise provided by applicable law. A shareholder may vote either in person or by proxy executed in writing by the shareholder or by his or her duly authorized attorney-in-fact. A telegram, telex, cablegram, e-mail or other form of electronic transmission permitted under Texas law 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 for the purposes of this Section 2.06, provided that any such electronic transmission must contain or be accompanied by information from which it can be determined that the transmission has been authorized by the shareholder.

If the Board of Directors fails to establish a record date, the record date shall be the date on which notice of the meeting is mailed or the date on which the resolution of the Board of Directors declaring such distribution or share dividend is adopted, as the case may be.

2.08      Voting List .

Such list shall be kept on file at the

registered office or the principal executive office of the Corporation and shall be subject to inspection by any shareholder at any time during regular business hours for a period of at least ten (10) days prior to such meeting. Alternatively, the list of shareholders may be kept on a reasonably accessible electronic network, if the information required to gain access to the list is provided with the notice of the meeting. Such list shall also be produced and kept open at the time and place of the meeting and shall be subject to the inspection of any shareholder during the whole time of the meeting. If the meeting is held by means of remote communication, the list must be open to the examination of any shareholder for the duration of the meeting on a reasonably accessible electronic network, and the information required to access the list must be provided to shareholders with the notice of the meeting. The Corporation’s original stock transfer records shall be prima-facie evidence as to which shareholders are entitled to examine such list or to vote at any meeting of shareholders.

(b)      Failure to comply with the requirements of this section shall not affect the validity of any action taken at any meeting of shareholders.

(c)      An officer or agent having charge of the stock transfer records who shall fail to prepare the list of shareholders or keep the same on file for a period of ten (10) days, or produce and keep it open for inspection as provided in this Article 2, shall be liable to any shareholder suffering damage on account of such failure, to the extent of such damage. In the event that such officer or agent does not receive notice of a meeting of shareholders sufficiently in advance of the date of such meeting to reasonably enable such officer or agent to comply with the duties prescribed by these Bylaws, the Corporation, but not such officer or agent, shall be liable to any shareholder suffering damage on account of such failure, to the extent of such damage.

(2) For nominations or other business to be properly brought before an annual meeting by a shareholder pursuant to clause (c) of paragraph (a)(1) of this Section 2.09, the shareholder must have given timely notice thereof in writing to the Secretary of the Corporation and such other business must be a proper matter for shareholder action. To be timely, a shareholder’s notice must set forth all of the information required by this Section 2.09 and shall be delivered to the Secretary at the principal executive offices of the Corporation not later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the first anniversary of the preceding year’s annual meeting; provided, however, that in the event that the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, notice by the shareholder to be timely must be so delivered not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made. In no event shall the public announcement of an adjournment of an annual meeting commence a new time period for the giving of a shareholder’s notice as described above. Such shareholder’s notice shall 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 in an election contest, or is otherwise required, in each case pursuant to Regulation 14A (or any successor provision) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules promulgated thereunder (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 any other business that the shareholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting and any material interest in such business of such shareholder and the beneficial owner, if any, on whose behalf the proposal is made; and (c) as to the shareholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (i) the name and address of such shareholder, as they appear on the Corporation’s books, and of such beneficial owner, (ii) the class and number of shares of the Corporation which are owned beneficially and of record by such shareholder and such beneficial owner, (iii) a description of any agreement, arrangement or understanding with respect to the nomination or proposal between or among such shareholder and such beneficial owner, any of their respective affiliates or associates, and any others acting in concert with any of the foregoing, (iv) a description of any agreement, arrangement or understanding (including any derivative or short positions, profit interests, options, warrants, stock appreciation or similar rights, hedging transactions, and borrowed or loaned shares) that has been entered into as of the date of the shareholder’s notice by, or on behalf of, such shareholder and such beneficial owner, the effect or intent of which is to mitigate loss to, manage risk or benefit of share price changes for, or increase or decrease the voting power of, such shareholder and such beneficial owner, with respect to shares of stock

of the Corporation, (v) a representation that the shareholder is a holder of record of stock of the Corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to propose such business or nomination, and (vi) a representation whether the shareholder or the beneficial owner, if any, intends or is part of a group which intends (a) to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the Corporation’s outstanding capital stock required to approve or adopt the proposal or elect the nominee or (b) otherwise to solicit proxies from shareholders in support of such proposal or nomination. The foregoing notice requirements shall be deemed satisfied by a shareholder if the shareholder has notified the Corporation of his or her intention to present a proposal at an annual meeting in compliance with Rule 14a-8 (or any successor thereof) promulgated under the Exchange Act and such shareholder’s proposal has been included in a proxy statement that has been prepared by the Corporation to solicit proxies for such annual meeting. The Corporation may require any proposed nominee to furnish such other information as it may reasonably require to determine the eligibility of such proposed nominee to serve as a director of the Corporation. Notwithstanding the foregoing, the information required by clauses (a)(2)(c)(ii), (a)(2)(c)(iii) and (a)(2)(c)(iv) of this Section 2.09 shall be updated by such shareholder and beneficial owner, if any, not later than 10 days after the record date for the meeting to disclose such information as of the record date.

(3) Notwithstanding anything in the second sentence of subsection (a)(2) of this Section 2.09 to the contrary, in the event that the number of directors to be elected to the Board of Directors is increased and there is no public announcement naming all of the nominees for director or specifying the size of the increased Board of Directors made by the Corporation at least 100 days prior to the first anniversary of the preceding year’s annual meeting, a shareholder’s notice required by this Section 2.09 shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary at the principal executive offices of the Corporation not later than the close of business on the 10th day following the day on which such public announcement is first made by the Corporation.

(b) Special Meetings of Shareholders . Only such business shall be conducted at a special meeting of shareholders as shall have been brought before the meeting pursuant to the Corporation’s notice of meeting. Nominations of persons for election to the Board of Directors may be made at a special meeting of shareholders at which directors are to be elected pursuant to the Corporation’s notice of meeting (1) by or at the direction of the Board of Directors or (2) by any shareholder of the Corporation who is a shareholder of record at the time of giving of notice provided for in this Section 2.09, who shall be entitled to vote at the meeting and who complies with the notice procedures set forth in this Section 2.09. In the event the Corporation calls a special meeting of shareholders for the purpose of electing one or more directors to the Board of Directors,

any such shareholder may nominate a person or persons (as the case may be), for election to such position(s) as specified in the Corporation’s notice of meeting, if the shareholder’s notice required by subsection (a)(2) of this Section 2.09 shall be delivered to the Secretary at the principal executive offices of the Corporation not earlier than the close of business on the 120th day prior to such special meeting and not later than the close of business on the later of the 90th day prior to such special meeting or the 10th day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting. In no event shall the public announcement of an adjournment of a special meeting commence a new time period for the giving of a shareholder’s notice as described above.

(1) Only such persons who are nominated in accordance with the procedures set forth in this Section 2.09 shall be eligible to serve as directors and only such business shall be conducted at a meeting of shareholders as shall have been brought before the meeting in accordance with the procedures set forth in this Section 2.09. Except as otherwise provided by law, the Certificate of Formation or these Bylaws, the Chairman of the meeting shall have the power and duty to determine whether a nomination or any business proposed to be brought before the meeting was made, or proposed, as the case may be, in accordance with the procedures set forth in this Section 2.09 and, if any proposed nomination or business is not in compliance with this Section 2.09, to declare that such defective proposal or nomination shall be disregarded.

(2) For purposes of this Section 2.09, “public announcement” shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to the Exchange Act.

(3) Notwithstanding the foregoing provisions of this Section 2.09, a shareholder shall also comply with all applicable requirements of applicable state law and the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Section 2.09. Nothing in this Section 2.09 shall be deemed to affect any rights of (a) any shareholder to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 (or any successor provision) under the Exchange Act or (b) the holders of any series of Preferred Stock to elect directors under specified circumstances.

ARTICLE 3.

DIRECTORS

3.01      Powers . The property, business and affairs of the Corporation and all corporate powers shall be managed by the Board of Directors, subject to any limitation imposed by applicable law, the Certificate of Formation or these Bylaws.

3.02      Number and Term of Directors . The number of Directors shall be set at thirteen (13), but the number of Directors may be increased or decreased (provided such decrease does not shorten the term of any incumbent Director) from time to time by resolution of the Board of Directors, provided the number of Directors shall never be less than three (3) nor more than twenty (20). The directors shall be classified with respect to the time for which they severally hold office into three (3) classes. Such classes shall be as nearly equal in number as possible as determined by the Board of Directors. The terms of office of the initial directors constituting the first class expired at the first annual meeting of shareholders after the initial election of the directors of that class (and thereafter such class shall hold office for a three-year term expiring at the annual meeting of shareholders), the terms of office of the initial directors constituting the second class expired at the second annual meeting of shareholders after the initial election of the directors of that class (and thereafter such class shall hold office for a three-year term expiring at the annual meeting of shareholders), and the terms of office of the initial directors constituting the third class expired at the third annual meeting of shareholders after the initial election of the directors of that class (and thereafter such class shall hold office for a three-year term expiring at the annual meeting of shareholders), with the members of each class to hold office until their successors are elected and qualified, until his or her death or retirement or until he or she shall resign or be removed in the manner provided in the Bylaws. In any such event, such Director’s successor shall become a member of the same class of directors as his or her predecessor. Any directorship created by reason of an increase in the number of directors in accordance with this Section 3.02 may be filled in accordance with the provisions of Section 3.05 of these Bylaws.

3.03      Election .

(a)      Directors shall be elected by the affirmative vote of a majority 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; provided, however, that if as of the record date for such annual meeting of shareholders the number of nominees for director exceeds the number of positions on the Board of Directors to be filled by election at such meeting, then the directors shall be elected by a plurality of the votes cast. For purposes of this Section 3.03, a “majority of the votes cast” means that the number of shares cast “for” a director’s election exceeds the number of shares cast “against” a director’s election, with abstentions and broker non-votes counting as votes neither “for” nor “against” such director’s election. No shareholder shall be entitled to cumulate such shareholder’s votes in the election of directors.

(b)      If a nominee for director fails to receive a majority of the votes cast and such nominee is an incumbent director, then the director shall promptly tender his or her resignation to the Board of Directors, the effectiveness of which shall be conditioned upon, and subject to, acceptance by the Board of Directors. The Nominating Committee of the Board of Directors will make a recommendation to the Board of Directors as to whether to accept or reject the tendered resignation or whether other action should be taken. Thereafter, the Board of Directors will vote to decide whether to accept the recommendation of the Nominating Committee and will promptly publicly disclose its decision regarding the tendered resignation and the rationale behind its decision. The Nominating Committee in making its recommendation, and the Board of Directors in making its decision, may each consider any factors or other information that they consider appropriate and relevant. The director who tenders his or her resignation will not participate in the recommendation of the Nominating Committee or the decision of the Board of Directors with respect to his or her resignation or in any deliberations related thereto.

(c)      If a director’s resignation is accepted by the Board of Directors pursuant to Section 3.03(b), or if a nominee for director is not elected and the nominee is not an incumbent director, then the Board of Directors, in its sole discretion, may fill the resulting vacancy pursuant to Section 3.05 or may decrease the size of the Board of Directors pursuant to Section 3.02. If a director’s resignation is not accepted by the Board of Directors, then such director will continue to serve until his or her successor is elected and qualified, until his or her death or retirement or until he or she shall resign or be removed in the manner provided in these Bylaws

3.04      Removal of Directors . At any meeting of shareholders called expressly for the purpose of removing a director, any director or the entire Board of Directors may be removed, for cause only, by a vote of the holders of a majority of the shares then entitled to vote at any election of directors.

3.05      Vacancies . Any vacancy in the Board of Directors resulting from the death, resignation or removal of a director or other cause 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, even if the remaining directors constitute less than a quorum of the Board of Directors. A director elected to fill such a vacancy shall be elected for the unexpired term of his or her predecessor in office. Newly created directorships resulting from an increase in the number of directorships may be filled by election at an annual or special meeting of shareholders called for that purpose or by the Board of Directors; provided, however, that the number of directorships so filled by the Board of Directors shall not exceed two (2) directorships between two successive annual meetings of shareholders. Any additional director so elected shall be elected for a term of office continuing until the next election of one or more directors by the Corporation’s shareholders.

3.06      Meetings . Meetings of the Board of Directors shall be held at the principal business office of the Corporation or at any other place (within or without the State of Texas) as the Board of Directors may from time to time select.

3.07      Annual Meeting . The Board of Directors shall meet each year immediately after the annual meeting of the Corporation’s shareholders at the place that meeting has been held, or at such other time each year as the Board of Directors shall determine, to elect the Corporation’s officers and consider other business. Notice of the annual meeting of the Board of Directors shall not be required.

3.08      Regular Meetings . Regular meetings of the Board of Directors shall be held at such places and at such times as may be designated or determined from time to time by resolution of the Board of Directors. Notice of such regular meetings shall not be required.

3.09      Special Meetings . Special meetings of the Board of Directors may be called at any time by the Chairman of the Board, the President or by any member of the Board of Directors. Notice of such special meetings may be by First Class mail or by any form of electronic transmission permitted under Texas law (upon consent of the director receiving the notice by electronic transmission) and should set forth the time, place and purpose of the special meeting. Such notice shall be sent to each director at least 24 hours before the meeting, provided that in the case of personal contact or by telephone, the special meeting may be called on 12 hours’ notice.

3.10      Quorum of Directors . At all meetings of the Board of Directors a majority of the directors shall constitute a quorum for the transaction of business and the act of a majority of the directors present at any meeting at which there is a quorum shall be the act of the Board of Directors. If a quorum shall not be present at any meeting 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.

3.11      Presumption of Assent . A director who is present at any meeting of the Board of Directors at which action on any corporate matter is taken shall be presumed to have assented to the action taken unless his or her dissent shall be entered in the minutes of the meeting or unless he or she shall file his or her written dissent to such action with the person acting as secretary of the meeting before the adjournment thereof or shall forward such dissent by 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.

3.12      Committees . The Board of Directors may from time to time designate members of the Board of Directors to constitute committees, which shall in each case consist of such number of directors and shall have and may exercise such power as the Board may determine and specify in the respective resolutions appointing them, subject to restrictions set forth under Texas law. The Board of Directors may also dissolve any committee so constituted. A majority of all the members of any such committee may determine its action and fix the time and place of its meeting, unless the Board of Directors shall otherwise provide. The Board of Directors may remove a member of a committee appointed by the Board if the Board determines the removal is in the best interests of the Corporation;  provided  that the removal of a committee member shall be without prejudice to the contract rights, if any, of the person so removed. Appointment of a committee member shall not of itself create contract rights.

3.13      Compensation . Directors shall receive such compensation for their services as directors as may be determined by resolution of the Board of Directors. The receipt of such compensation shall not preclude any Director from serving the Corporation in any other capacity and receiving compensation therefore.

Shares may not be issued until the full amount of the consideration fixed therefore has been paid.

5.03      Lost, Stolen or Destroyed Certificates . 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, stolen or destroyed if the person claiming the certificate to be lost, stolen or destroyed makes an affidavit of that fact and files with the Corporation a sufficient indemnity bond by the person claiming the certificate to be lost, stolen or destroyed, and when authorizing such issue of a new certificate, the Board of Directors may, in its discretion and as a condition precedent to the issuance thereof, prescribe such other terms and conditions as it deems expedient or necessary 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.

5.04      Registration of Transfers . Shares of stock shall be transferable only on the books of the Corporation by the holder thereof in person or by his or her duly authorized attorney.

The transfer agent is authorized by the Corporation to record and maintain the Corporation’s common stock in book entry form or electronically without the issuance of a physical stock certificate. The transfer agent will provide for paperless direct registration of securities and will allow electronic transfer of securities between a participating transfer agent and a broker-dealer clearing through the Depository Trust Company (DTC).

5.05      Registered Shareholders . The Corporation shall be entitled to recognize the exclusive right of a person registered on its books as the owner of shares to receive dividends, and to vote as such owner, and 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.

The Corporation may (but shall not be required to) pay or reimburse reasonable expenses incurred by any person of the type eligible for indemnification under this Article 6 who is made or is threatened to be made a defendant or respondent in any proceeding in advance of the final disposition of such proceeding and without any determination as to the person’s ultimate entitlement to indemnification if the Corporation receives (i) a written affirmation from such person of the person’s good faith belief that the person has met the standard of conduct necessary for indemnification under this Article 6 and applicable law and (ii) a written undertaking by or on behalf of the person to repay the amount paid or reimbursed to the person by the Corporation if it is finally determined that the person is not entitled to the indemnification of such person under this Article 6 or indemnification is prohibited by applicable law.

6.03      Appearance as a Witness .

6.05      Nonexclusivity of Rights . The right to indemnification and the advancement and payment of expenses conferred by this Article 6 shall not be exclusive of any other right which a director or officer of the Corporation or other person indemnified pursuant to this Article 6 may have or hereafter acquire under any law, provision of the Certificate of Formation or these Bylaws, agreement, vote of shareholders or otherwise.

6.06      Savings Clause . If this Article 6 or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify and advance expenses to each director, officer, and other person indemnified pursuant to this Article 6 to the extent permitted by any applicable portion of this Article 6 that shall not have been invalidated.

In the absence of any action by the Board of Directors, the date upon which the Board of Directors adopts the resolution declaring the dividend shall be the record date.

(c) By resolution the Board of Directors may create such reserve or reserves out of the earned surplus of the Corporation for any proper purpose or purposes and may increase, decrease or abolish any such reserve in the same manner.
