Meetings of Shareholders

     Section 1. Place of Meetings. The Board of Directors may designate any place, either within or without the State of Texas, as the place of meeting for any annual meeting or for any special meeting called by the Board. A waiver of notice signed by all shareholders entitled to vote at a meeting may designate any place, either within or without the State of Texas, as the place for the holding of such meeting. If no designation is made, or if a special meeting be otherwise called, the place of meeting shall be the principal office of the Corporation.

-1-

     Section 2. Annual Meeting. The annual meeting of shareholders commencing with the year 1982 shall be held at such time, on such day and at such place as may be designated by the Board of Directors, at which time the shareholders shall elect a Board of Directors and transact such other business as may properly be brought before the meeting.

     Section 3. Special Meetings. Special meetings of the shareholders for any purpose or purposes, unless otherwise prescribed by law or by the Articles of Incorporation, may be called by the Chairman of the Board, the Board of Directors or the holders of not less than one-tenth (1/10) of all of the shares entitled to vote at the meetings. Business transacted at all special meetings shall be confined to the purpose or purposes stated in the call.

     Section 4. Notice of Meetings. Written or printed notice of all meetings of shareholders stating the place, day and hour thereof, and in the case of a special meeting the purpose or purposes for which the meeting is called, shall be personally delivered or mailed, not less than ten (10) days nor more than fifty (50) days prior to the date of the meeting, to the shareholders of record entitled to vote at such meeting. If mailed, the notice shall be addressed to the shareholders as their address appears on the stock transfer books of the Corporation and the postage shall be prepaid.

     Section 5. Voting Lists. The officer or agent having charge of the stock transfer books for shares of the Corporation shall make, at least ten (10) days before each meeting of the shareholders, a complete list of shareholders entitled to vote at such meeting or any adjournment thereof, arranged in alphabetical order, with the address of each and the number of shares held by each, which list, for a period of ten (10) days prior to such meeting, shall be kept on file at the registered office of the

-2-

Corporation and shall be subject to inspection by any shareholders at any time during usual business hours. 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 for the duration of the meeting. The original stock transfer books shall be prima-facie evidence as to who are the shareholders entitled to examine such list or transfer books or to vote at any meeting of shareholders.

     Section 6. Quorum. The holders of a majority of the shares entitled to vote, present in person or represented by proxy, shall constitute a quorum at all meetings of the shareholders for the transaction of business, except as otherwise provided by law, by the Articles of Incorporation or by these Bylaws. If, however, such quorum shall not be present or represented at any meeting of the shareholders, the shareholders entitled to vote at such meeting, present in person or represented by proxy, shall have the power to adjourn the meeting from time to time without notice other than announcement at the meeting until a quorum shall be present or represented. At such adjourned meeting at which a quorum shall be present or represented any business may be transacted which might have been transacted at the meeting as originally convened.

     Section 7. Organization. The Chairman of the Board, if one shall be elected, shall preside at all meetings of the shareholders. In his absence or should a Chairman of the Board not be elected, the President or a Vice President shall preside. In the absence of all of these officers any shareholder or the duly appointed proxy of any shareholder may call the meeting to order and a chairman shall be elected from among the shareholders present.

     The Secretary of the Corporation shall act as secretary at all meetings of the shareholders. In his absence an Assistant Secretary shall so act and in the absence

-3-

of all of these officers the presiding officer may appoint any person to act as secretary of the meeting.

     Section 8. Proxies. At any meeting of the shareholders every shareholder entitled to vote at such meeting shall be entitled to vote in person or by proxy executed in writing by such shareholder or by his duly authorized attorney-in-fact. No proxy shall be valid after eleven (11) months from the date of its execution unless such proxy otherwise provides. A proxy shall be revocable unless expressly provided therein to be irrevocable or unless otherwise made irrevocable by law.

     Section 9. Voting of Shares. Except as otherwise provided by law, the Articles of Incorporation or these Bylaws, each shareholder shall have one (1) vote for each share having voting rights registered in his name on the books of the Corporation at the time of the closing of the stock transfer books (or at the record date) for such meeting. When a quorum is present at any meeting the vote of holders of a majority of the shares entitled to vote, present in person or represented by proxy, shall decide any matter submitted to such meeting, unless the matter is one upon which by law or by express provision of the Articles of Incorporation or of these Bylaws the vote of a greater number is required, in which case the vote of such greater number shall govern and control the decision of such matter.

     Section 10. Voting of Shares by Certain Holders. Shares standing in the name of another corporation may be voted by such officer, agent or proxy as the bylaws of such corporation may authorize or, in the absence of such authorization, as the board of directors of such corporation may determine.

     Shares held by an administrator, executor, guardian or conservator may be voted by him so long as such shares forming a part of an estate are in the possession and form a part of the estate being served by him, either in person or by proxy,

-4-

without a transfer of such shares into his name. Shares standing in the name of a trustee may be voted by him, either in person or by proxy, but no trustee shall be entitled to vote shares held by him without a transfer of such shares into his name as trustee.

     Shares standing in the name of a receiver may be voted by such receiver, and shares held by or under the control of a receiver may be voted by such receiver without the transfer thereof into his name if authority to do so be contained in an appropriate order of the court by which such receiver was appointed.

     A shareholder whose shares are pledged shall be entitled to vote such shares until the shares have been transferred into the name of the pledgee, and thereafter the pledgee shall be entitled to vote the shares so transferred.

     Shares of its own stock belonging to the Corporation, shares of its own stock owned by another corporation the majority of the voting stock of which is owned or controlled by the Corporation, and shares of its own stock held by the Corporation in a fiduciary capacity shall not be voted, directly or indirectly, at any meeting, and shall not be counted in determining the total number of outstanding shares at any given time.

     Section 11. Election of Directors. At each election for Directors each shareholder entitled to vote at such election shall, unless otherwise provided by the Articles of Incorporation or by applicable law, have the right to vote the number of shares owned by him for as many persons as there are to be elected and for whose election he has a right to vote. Unless otherwise provided by the Articles of Incorporation, no shareholder shall have the right or be permitted to cumulate his votes on any basis.

-5-

     Section 12. Telephone Meetings. Shareholders may participate in and hold a meeting of the shareholders by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other and participation in a meeting pursuant to this Section shall constitute presence in person at such meeting, except where a person participates in the meeting for the express purpose of objecting to the transaction of any business on the ground that the meeting is not lawfully called or convened.

     Section 13. Action Without Meeting. Any action required by any provision of law or of the Articles of Incorporation or these Bylaws to be taken at a meeting of the shareholders or any action which may be taken at a meeting of the shareholders may be taken without a meeting if a consent in writing, setting forth the action so taken, shall be signed by all of the shareholders entitled to vote with respect to the subject matter thereof, and such consent shall have the same force and effect as a unanimous vote of the shareholders.

ARTICLE III

Directors

     Section 1. Number and Qualification. The property, business and affairs of the Corporation shall be managed and controlled by a Board of Directors composed of not less than one (1) nor more than seven (7) members who shall be elected annually by the shareholders. Directors need not be residents of the State of Texas or shareholders of the Corporation. The number of Directors may be increased or decreased by resolution adopted by a majority of the Board of Directors. No decrease in the number of Directors shall have the effect of shortening the term of any incumbent Director.

-6-

     Section 2. Election and Term of Office. The Directors shall be elected at the annual meeting of the shareholders (except as provided in Section 5 of this Article). Each Director elected shall hold office until his successor shall be elected at an appropriate annual meeting of the shareholders and shall qualify, or until his death, his resignation or his removal in the manner hereinafter provided.

     Section 3. Resignation. Any Director may resign at any time by giving written notice to the President or Secretary. Such resignation shall take effect at the time specified therein and unless otherwise specified therein the acceptance of such resignation shall not be necessary to make it effective.

     Section 4. Removal. At any special meeting of the shareholders called expressly for that purpose any Director or Directors, including the entire Board of Directors, may be removed, either with or without cause, and another person or persons may be elected to serve for the remainder of his or their term by a vote of the holders of a majority of all shares outstanding and entitled to vote at an election of directors. In case any vacancy so created shall not be filled by the shareholders at such meeting, such vacancy may be filled by the Directors as provided in Section 5 of this Article.

     Section 5. Vacancies. If any vacancy shall occur in the Board of Directors such vacancy may, subject to the provisions of Section 4 of this Article, be filled by the affirmative vote of the remaining Directors though less than a quorum of the Board of Directors; provided however, any Directorship to be filled by reason of an increase in the number of Directors shall be filled by election at an annual meeting or at a special meeting of shareholders called for that purpose. A Director elected to fill a vacancy shall be elected for the unexpired term of his predecessor in office.

-7-

     Section 6. General Powers. In addition to the powers and authorities expressly conferred upon them by these Bylaws, the Board of Directors may exercise all such powers of the Corporation and do all such lawful acts and things as are not by law or by the Articles of Incorporation or by these Bylaws directed or required to be exercised or done by the shareholders.

     Section 7. Compensation. Directors as such shall not receive any stated salary for their services, but by resolution of the Board a fixed sum for expenses of attendance, if any, may be allowed for attendance at any regular or special meeting of the Board provided that nothing herein contained shall be construed to preclude any Director from serving the Corporation in any other capacity and receiving compensation therefor. Members of special or standing committees may be allowed like compensation for attending committee meetings.

Neither the purpose of nor the business to be transacted at any special meeting of the Board of Directors need be specified in the notice or waiver of notice of such meeting.

     Section 5. Quorum and Action. At all meetings of the Board the presence of a majority of the Directors shall be necessary and sufficient to constitute a quorum for the transaction of business and the act of a majority of the Directors at any 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 law, the Articles of Incorporation or these Bylaws. If a quorum shall not be present at any meeting of Directors, the Directors present may adjourn the meeting from time to time without notice other than announcement at the meeting until a quorum shall be present.

     Section 6. Presumption of Assent to Action. A Director who is present at a meeting of the Board at which action on any corporate matter is taken shall be presumed to have assented to the action taken unless his dissent shall be entered in the minutes of the meeting or unless he shall file his written dissent to such action with the 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

-9-

adjournment of the meeting. Such right to dissent shall not apply to a Director who voted in favor of such action.

     Section 7. Telephone Meetings. Directors may participate in and hold a meeting of the Board of Directors by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other and participation in a meeting pursuant to this Section shall constitute presence in person at such meeting, except where a person participates in the meeting for the express purpose of objecting to the transaction of any business on the ground that the meeting is not lawfully called or convened.

In case any officer who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer before such certificate is issued, it may be issued with the same effect as if he were such officer at the date of its issuance.

     All certificates issued by the Corporation shall bear the following legend with respect to denial of preemptive rights:

“Preemptive rights of shareholders to acquire unissued or treasury shares of the Corporation are denied in Article Six of the Articles of Incorporation, a copy of which is on file in the office of the Secretary of State of Texas and will be furnished to any shareholder without charge upon written request to the Corporation at its principal place of business or registered office.”

-16-

Subject to any restrictions upon transfer contained herein or otherwise provided by law affecting outstanding shares of capital stock of the Corporation, upon surrender to the Corporation or the transfer agent of the Corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignment or authority to transfer and satisfaction of the Corporation that the requested transfer complies with the provisions of applicable state and federal laws and regulations and any agreements to which the Corporation is a party, the Corporation shall issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books.

     Section 3. Ownership of Shares. The Corporation shall be entitled to treat the holder of record of any share or shares 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 the laws of the State of Texas.

ARTICLE IX

Indemnities

     Section 1. Indemnification of Directors and Officers. (a) The corporation shall indemnify every director or officer or former director or officer of the corporation or any person who may have served at its request as a director or officer (or in a similar capacity) of another corporation, partnership, joint venture, trust, other enterprise or employee benefit plan, against reasonable expenses (including attorneys’ fees), damages, fines (including any excise taxes assessed against a person with respect to an employee benefit plan), penalties, judgments, amounts paid in settlement, and other liabilities actually and reasonably incurred by him in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, to which he may be made a party or in which he may become involved by reason of his being or having been such a director or officer (whether or not involving action in his official capacity as director or officer), except that no indemnification shall be made under this subsection (a) in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable for gross negligence, recklessness or willful misconduct in the performance of his duty to the corporation, unless and only to the extent that a court of appropriate jurisdiction shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity.

     (b) Any indemnification under subsection (a) (unless ordered by a court of appropriate jurisdiction) shall be made by the corporation only as authorized in the

-20-

specific case upon a determination that indemnification of the director or officer is proper in the circumstances because he is not guilty of gross negligence, recklessness or willful misconduct in the performance of his duty to the corporation. Such determination shall be made (1) by the board of directors by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding; or (2) if such a quorum cannot be obtained, then by a majority vote of a committee of the board, duly designated to act in the matter by a majority vote of the full board (in which designation directors who are parties may participate), consisting solely of two or more directors not at the time parties to such proceeding; or (3) by special legal counsel, selected by the board of directors or a committee thereof by vote as set forth in clauses (1) or (2) of this subsection (b) or, if the requisite quorum of the full board cannot be obtained therefor and such committee cannot be established, by a majority vote of the full board (in which selection directors who are parties may participate); or (4) by the shareholders. In the event a determination is made under this subsection (b) that the director or officer has met the applicable standard of conduct as to some matters but not as to others, amounts to be indemnified may be reasonably prorated.

     (c) Expenses incurred in appearing at, participating in or defending any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, shall be paid by the corporation at reasonable intervals in advance of the final disposition of such action, suit or proceeding after a determination is made in the manner specified by subsection (b) that the information then known to those making the determination (without undertaking further investigation for purposes thereof) does not establish that indemnification would not be permissible under subsection (a), and upon receipt by the corporation of (A) a written affirmation by the director or officer of his good faith belief that he has met the

-21-

standard of conduct necessary for indemnification by the corporation as authorized in this Section, and (B) a written undertaking by or on behalf of the director or officer to repay such amount unless it shall ultimately be determined that he is entitled to be indemnified by the corporation as authorized in this Section.

     (d) It is the intent of the corporation to indemnify the persons referred to in this Section to the fullest extent permitted by law. The indemnification provided by this Section shall not be deemed exclusive of any other rights to which those seeking indemnification may be entitled under any law, by-law, agreement, vote of stockholders or disinterested directors, or otherwise, or under any policy or policies of insurance purchased and maintained by the corporation on behalf of any such director or officer, both as to action in his official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director or officer, and shall inure to the benefit of the heirs, executors and administrators of such a person.

     (e) The indemnification provided by this Section shall be subject to all valid and applicable laws, and, in the event this Section or any of the provisions hereof or the indemnification contemplated hereby are found to be inconsistent with or contrary to any such valid laws, the latter shall be deemed to control and this Section shall be regarded as modified accordingly, and, as so modified, to continue in full force and effect.
