The officers and transfer agents issuing shares of the Corporation shall ensure that the total number of shares outstanding at any given time does not exceed this number. Such officers and agents shall advise the Board at least annually of the authorized shares remaining available to be issued. No shares shall be issued for less than the par value stated in the Articles of Incorporation. Each Charter provision shall be observed until amended by Restated Articles or Articles of Amendment duly filed with the Secretary of State. 1.02 REGISTERED AGENT OR OFFICE - REQUIREMENT OF FILING CHANGES WITH SECRETARY OF STATE The address of the Registered Office provided in the initial Articles of Incorporation, as duly filed with the Secretary of State for the State of Texas is: 9400 North Central Expressway, Suite 500, Dallas, Texas 75231. The name of the Registered Agent of the Corporation at such address, as set forth in its initial Articles of Incorporation, is: The Registered Agent or Office may be changed by filing appropriate documents with the Secretary of State, and not otherwise. Such filing shall be made promptly with each change. Arrangements for each change in Registered Agent or Office shall ensure that the Corporation is not exposed to the possibility of a default judgment. Each successive Registered Agent shall be of reliable character and well informed of the necessity of immediately furnishing the papers of any lawsuit against the Corporation to its attorneys. 1.03 INITIAL BUSINESS OFFICE The address of the initial principal business office of the Corporation shall be: 9400 North Central Expressway, Suite 510, Dallas, Texas 75231. The Corporation may have additional business offices within the State of Texas, and where it may be duly qualified to do business outside of Texas, as the Board of Directors may from time to time designate or the business of the Corporation may require. 1.04 AMENDMENT OF BYLAWS The Board of Directors may alter, amend, or repeal these Bylaws, and adopt new Bylaws. All such Bylaw changes shall take effect upon adoption by the Directors, subject to repeal or change by the Shareholders. Notice of Bylaws changes shall be given in or before notice of the Shareholders' meeting following their adoption. ARTICLE TWO DIRECTORS AND DIRECTORS' MEETINGS 2.01 ACTION BY CONSENT OF BOARD WITHOUT MEETING Any action required or permitted to be taken by the Board of Directors may be taken without a meeting, and shall have the same force and effect as a unanimous vote of Directors, if all members of the Board consent in writing to the action. Such consent may be given individually or collectively. 2.02 PLACE OF MEETINGS Meetings of the Board of Directors shall be held at the business office of the Corporation or at such other place within or without the State of Texas as may be designated by the Board. 2.03 REGULAR MEETINGS Regular meetings of the Board of Directors shall be held, without call or notice, immediately following each annual meeting of the Shareholders of this Corporation, and at such other regular times as the Directors may determine. 2.04 CALL OF SPECIAL MEETING Special meetings of the Board of Directors for any purpose may be called at any time by the President or, if the President is absent or unable or refuses to act, by any Vice President or any two Directors. Written notices of the special meetings, stating the time and place of the meeting, shall be mailed ten days before, or telegraphed or personally delivered so as to be received by each Director not later than two days before, the day appointed for the meeting. Notice of meetings need not indicate an agenda. Generally, a tentative agenda will be included, but the meeting shall not be confined to any agenda included with the notice. Meetings provided for in these Bylaws shall not be invalid for lack of notice if all persons entitled to notice are present at the meeting in person or by proxy and do not object to the notice given or if such persons consent to the meeting in writing. Such consent may be given either before or after the meeting. Upon providing notice, the Secretary or other officer sending notice shall sign and file in the Corporate record book a statement of the details of notifying each Director. If such statement should later not be found in the Corporate record book, due notice shall be presumed. 2 2.05 QUORUM The presence at any Directors' meeting of a majority of the authorized number of Directors shall be necessary to constitute a quorum to transact any business, except to adjourn. If a quorum is present, every act done or resolution passed by a majority of the Directors present shall be the act of the Board of Directors. 2.06 ADJOURNMENT - NOTICE OF ADJOURNED MEETINGS A quorum of the Directors may adjourn any Directors' meeting to meet again at a stated hour on a stated day. Notice of the time and place where an adjourned meeting will be held need not be given to absent Directors if the time and place is fixed at the adjourned meeting. In the absence of a quorum, a majority of the Directors present may adjourn to a set time and place if notice is duly given to the absent members, or until the time of the next regular meeting of the Board. 2.07 CONDUCT OF MEETINGS At every meeting of the Board of Directors, the Chairman of the Board of Directors, if there is such an officer, and if not, the President, or in the President's absence, a Vice President designated by the President, or in the absence of such designation, a Chairman chosen by a majority of the Directors present, shall preside. The Secretary of the Corporation shall act as Secretary of the Board of Directors. When the Secretary is absent from any meeting, the Chairman may appoint any person to act as Secretary of that meeting. 2.08 POWERS OF THE BOARD OF DIRECTORS The business and affairs of the Corporation and all corporate powers shall be exercised by or under authority of the Board of Directors, subject to limitations imposed by law, the Articles of Incorporation, any applicable Shareholders' agreement, or by these Bylaws. 2.09 BOARD COMMITTEES - AUTHORITY TO APPOINT The Board of Directors may designate an executive committee and one or more other committees to conduct the business and affairs of the Corporation to the extent authorized by the resolution. The Board shall have the power at any time to change the powers and membership of, fill vacancies in, and dissolve any committee. Members of any committee shall receive such compensation as the Board of Directors may from time to time provide. The designation of any committee and the delegation of authority thereto shall not operate to relieve the Board of Directors, or any member thereof, of any responsibility imposed by law. 3 2.10 TRANSACTIONS WITH INTERESTED DIRECTORS Any contract or other transaction between the Corporation and any of its Directors (or any corporation or firm in which any of its Directors are directly or indirectly interested) shall be valid for all purposes notwithstanding the presence of that Director at the meeting during which the contract or transaction was authorized, and notwithstanding the Director's participation in that meeting. This Article shall apply only if the contract or transaction is just and reasonable to the Corporation at the time it is authorized and ratified, the interest of each Director is known or disclosed to the Board of Directors, and the Board nevertheless authorizes or ratifies the contract or transaction by a majority of the disinterested Directors present. Each interested Director is to be counted in determining whether a quorum is present, but shall not vote and shall not be counted in calculating the majority necessary to carry the vote. This Article shall not be construed to invalidate contracts or transactions that would be valid in its absence. 2.11 NUMBER OF DIRECTORS The number of Directors of this Corporation shall be three. No Director need be a Shareholder or a resident of Texas. The number of Directors may be increased or decreased from time to time by amendment to these Bylaws. Any decrease in the number of Directors shall not have the effect of shortening the tenure which any incumbent Director would otherwise enjoy. 2.12 TERM OF OFFICE Directors shall be entitled to hold office until their successors are elected and qualified. Election of Directors shall occur at each annual meeting of the Shareholders and may be held at any special meeting of Shareholders called specifically for that purpose. 2.13 REMOVAL OF DIRECTORS The entire Board of Directors or any individual Director may be removed from office by a vote of Shareholders holding a majority of the outstanding shares entitled to vote at an election of Directors. However, if less than the entire Board is to be removed, no one of the Directors may be removed if the votes cast against his removal would be sufficient to elect him if then cumulatively voted at an election of the entire Board of Directors. No Director may be so removed except at an election of the class of Directors of which he is a part. If any or all Directors are so removed, new Directors may be elected at the same meeting. Whenever a class or series of shares is entitled to elect one or more Directors under authority granted by the Articles of Incorporation, the provisions of this Paragraph apply to the vote of that class or series and not to the vote of the outstanding shares as a whole. 4 2.14 VACANCIES Vacancies on the Board of Directors shall exist upon the occurrence of any of the following events: (a) the death, resignation, or removal of any Director; (b) an increase in the authorized number of Directors; or (c) the failure of the Shareholders to elect the full authorized number of Directors to be voted for at any annual, regular, or special Shareholders' meeting at which any Director is to be elected. 2.14(a) DECLARATION OF VACANCY The Board of Directors may declare vacant the office of a Director if the Director: (a) is adjudged incompetent by a court order; (b) is convicted of a crime involving moral turpitude; or (c) fails to accept the office of Director, in writing or by attending a meeting of the Board of Directors, within thirty (30) days of notice of election. 2.14(b) FILLING VACANCIES BY DIRECTORS Vacancies other than those caused by an increase in the number of Directors may be filled by majority vote of the remaining Directors, though less than a quorum, or by a sole remaining Director. Each Director so elected shall hold office until a qualified successor is elected at a Meeting of the Shareholders. 2.14(c) FILLING VACANCIES BY SHAREHOLDERS Any vacancy caused by an increase in the number of Directors shall be filled by the Shareholders at an annual meeting or at a special meeting called for that purpose. The Shareholders may also elect a Director at any time to fill any vacancy not filled by the Directors. Upon the resignation of a Director tendered to take effect at a future time, the Board or the Shareholders may elect a successor to take office when the resignation becomes effective. 2.15 COMPENSATION Directors shall receive such compensation for their services as Directors as shall be determined from time to time by resolution of the Board. Any Director may serve the Corporation in any other capacity as an officer, agent, employee, or other wise, and receive compensation therefore. 2.16 INDEMNIFICATION OF DIRECTORS AND OFFICERS The Board of Directors shall authorize the Corporation to pay or reimburse any present or former Director or officer of the Corporation any costs or expenses actually and necessarily incurred by that officer in any action, suit, or proceeding to which the officer is made a party by reason of holding that position, provided, however, that no officer shall receive such indemnification if finally adjudicated therein to be liable for negligence or misconduct in office. This indemnification shall extend to good-faith 5 expenditures incurred in anticipation of threatened or proposed litigation. The Board of Directors may, in proper cases, extend the indemnification to cover the good faith settlement of any such action, suit, or proceeding, whether formally instituted or not. 2.17 INSURING DIRECTORS, OFFICERS, AND EMPLOYEES The Corporation may purchase and maintain insurance on behalf of any Director, officer, employee, or agent of the Corporation, or on behalf of any person serving at the request of the Corporation as a Director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise, against any liability asserted against that person and incurred by that person in any such corporation, whether or not the Corporation has the power to indemnify that person against liability for any of those acts.

Each such signed consent or waiver, or a true copy thereof, shall be placed in the minute book of the Corporation. 3.02 TELEPHONE MEETINGS Subject to the notice provisions required by these Bylaws and by the Business Corporation Act, Shareholders of the Corporation may participate in and hold a meeting by means of conference call or similar communication by which all persons participating can hear each other.

The list shall be kept on file at the Registered Office of the Corporation for a period of ten (10) days prior to the meeting, and shall be subject to inspection by any Shareholder-at any time during usual business hours. The list shall also be produced and kept open at the time and place of the meeting and shall be subject, during the entire time of the meeting, to the inspection of any Shareholder.

The Shareholder may cast all these votes for one candidate or may distribute the votes among any number of candidates. The candidates receiving the highest number of votes are elected, up to the number of vacancies to be filled. No Shareholder may cumulate votes unless that Shareholder shall have given written notice of his or her intention to do so to the Secretary of the Corporation on or before the day preceding the election at which the votes will be cumulated.

Each registrar appointed, if any, shall be an incorporated bank or trust company, either domestic or foreign. 6.07 CONDITIONS OF TRANSFER The party in whose name shares of stock stand on the books of the Corporation shall be deemed the owner thereof as regards the Corporation, provided that whenever any transfer of shares shall be made for collateral security, and not absolutely, written notice thereof shall be given to the Secretary of the Corporation, or to its transfer agent, if any, and such fact shall be stated in the entry of the transfer. 6.08 REASONABLE DOUBTS AS TO RIGHT TO TRANSFER When a transfer of shares is requested and there is reasonable doubt as to the right of the person seeking the transfer, the Corporation or its transfer agent, before recording the transfer of the shares on its books or issuing any certificate therefor, may require from the person seeking the transfer reasonable proof of that person's right to the transfer. If there remains a reasonable doubt of the right to the transfer, the Corporation may refuse a transfer unless the person gives adequate security or a bond of indemnity executed by a corporate surety or by two individual sureties satisfactory to the Corporation as to form, amount, and responsibility of sureties. The bond shall be conditioned to protect the Corporation, its officers, transfer agents, and registrars, or any of them, against any loss, damage, expense, or other liability to the transfer or the issuance of a new certificate for shares. ARTICLE SEVEN CORPORATE RECORDS AND FISCAL YEAR 7.01 MINUTES OF CORPORATE MEETINGS The Corporation shall keep at the Registered or principal office, or such other place as the Board of Directors may order, a book recording the minutes of all meetings of its Shareholders and Directors, with the time and place of each meeting, whether such meeting was regular or special, a copy of the notice given of such 14 meeting, or of the written waiver thereof, and, if it is a special meeting, how the meeting was authorized. The record book shall further show the names of those present at Directors' meetings, the number of shares present or represented at Share holders' meetings, and the proceedings of all meetings. 7.02 SHARE REGISTER The Corporation shall keep at the Registered or principal office, or at the office of the transfer agent, a share register, showing the names of the Shareholders, their addresses, the number and class of shares issued to each, the number and date of issuance of each certificate issued for such shares, and the number and date of cancellation of every certificate surrendered for cancellation. The above specified information may be kept on an information storage device such as electronic data processing equipment, provided that the equipment is capable of reproducing the information in clearly legible form for the purposes of inspection by any Shareholder, Director, Officer, or agent of the Corporation during regular business hours. If the Corporation elects taxation under internal Revenue Code (S) 1244 or Subchapter S, the officer issuing shares shall ensure that the appropriate requirements regarding issuance of shares are maintained in effect. 7.03 BOOKS OF ACCOUNT The Corporation shall maintain correct and adequate accounts of its properties and business transactions, including accounts of its assets, liabilities, receipts, disbursements, gains, losses, capital, surplus, and shares. The corporate bookkeeping procedures shall conform to accepted accounting practices for the business or businesses in which the Corporation is engaged. Subject to the foregoing, the chart of financial accounts shall be taken from, and designed to facilitate preparation of, current corporate tax returns. Any surplus, including earned surplus, paid-in surplus, and surplus arising from a reduction of stated capital, shall be classified according to source and shown in a separate account. If the Corporation elects taxation under Internal Revenue Code (S) 1244 or Subchapter S, the officers and agents maintaining the books of account and issuing shares shall ensure that the appropriate requirements are maintained in effect. 7.04 FISCAL YEAR The fiscal year of the Corporation shall be as determined by the Board of Directors and approved by the Internal Revenue Service. The Treasurer shall forthwith arrange a consultation with the Corporation's tax advisers, to determine if the Corporation is to have a fiscal year other than the calendar year. If so, the Treasurer shall file an election with the Internal Revenue Service as early as possible, and all correspondence with the I.R.S., including the application for the Corporation's Employer Identification Number, shall reflect such non-calendar year election. 15 I certify that these are the Bylaws of CH4 Marketing, Inc., as adopted on December 31, 1990. /s/ Joyce Berthier ------------------ Joyce Berthier, Secretary 16
