Each Series A Share will entitle the holder thereof to cast 100,000 votes on any matter coming before the shareholders of the Corporation. 3. Dividend rights. The holders of Series A Shares shall not be entitled to any preference in the payment of dividends.

Except as provided in or pursuant to Article IV(F) hereof, any vacancy on the Board (including any vacancy resulting from an increase in the authorized number of directors or from a failure of the shareholders to elect the full number of authorized directors) may, notwithstanding any resulting absence of a quorum of directors, be filled by a vote of at least two-thirds of the directors remaining in office, provided that the shareholders shall have the right to fill the vacancy at any special meeting called for such purpose prior to any such action by the Board. Vacancies on the Board may be filled only as provided in this Article IV(C). C. Removal. Except as provided in or pursuant to Article IV(F) hereof, any one or more directors may be removed at any time, (1) only for cause, by the holders of not less than two-thirds of the Total Voting Power (as defined in Article VII(C) hereof) that is present or represented at a special meeting of shareholders called for such purpose, voting together as a single class or (2) with or without cause, by the affirmative vote of at least two-thirds of all of the directors then constituting the Board of Directors; provided, however, that, if at any time after the Corporation has sold shares of Common Stock in a transaction registered under the Securities Act of 1933, as amended, a person is, directly or indirectly, the beneficial owner of more than 50% of the outstanding shares of Common Stock of the Corporation, a director may not be removed without cause. For purposes of this Article IV(D), (1) "cause" shall mean (a) a conviction of a director by a court of competent jurisdiction of a felony involving moral turpitude if such conviction is no longer subject to direct appeal or (b) an adjudication by a court of competent jurisdiction of liability for gross negligence or gross misconduct in the performance of the director's duty to the Corporation in a matter of substantial importance to the Corporation if such adjudication is no longer subject to direct appeal and (2) "beneficial owner" has the meaning assigned to that term in Article IV(E)(1). At the same meeting at which the directors or shareholders remove one or more directors, a successor or successors may be elected for the unexpired term of the director or directors removed. Except as set forth in this Article IV(D), or in any provision of these Articles of Incorporation relating to removal of directors elected by holders of Preferred Stock, directors shall not be subject to removal. D. Board Nominations. Except as provided in or pursuant to Article IV(F) hereof, only persons who are nominated in accordance with the procedures set forth in this Article IV(E) shall be eligible for election as directors. Nominations of persons for election to the Board of Directors of the Corporation may be made at a meeting of shareholders by or at the direction of the Board of Directors or by any shareholder of record of the Corporation entitled to vote at such meeting for the election of directors who complies with the notice procedures set forth in this Article IV(E). Such nominations, other than those made by or at the direction of the Board of Directors, shall be made pursuant to timely notice in writing to the Secretary of the Corporation. To be timely, a shareholder's notice shall be delivered to or mailed and received at the principal office of the Corporation not less than 45 days nor more than 90 days prior to the meeting; provided, however, that in the event that less than 55 days notice or prior public disclosure of the date of the meeting is given or made to shareholders, notice by the shareholder to be timely must be so received at the principal executive offices of the 49 Corporation no later than the close of business on the tenth day following the day on which such notice of the date of the meeting was mailed or such public disclosure was made. Such shareholder's notice shall set forth or include the following: 1. as to each person whom the shareholder proposes to nominate for election or re-election as a director, (a) the name, age, business address and residential address of such person, (b) the principal occupation or employment of such person, (c) the class and number of shares of capital stock of the Corporation of which such person is the beneficial owner (as defined in Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act")), (d) such person's written consent to being named in the proxy statement as a nominee and to serve as a director if elected and (e) any other information relating to such person that would be required to be disclosed in solicitations of proxies for the election of directors, or would be otherwise required, in each case pursuant to Regulation 14A promulgated under the Exchange Act; and 2. as to the shareholder of record giving the notice, (a) the name and address of such shareholder and (b) the class and number of shares of capital stock of the Corporation of which such shareholder is the beneficial owner (as defined in Rule 13d-3 promulgated under the Exchange Act). If requested in writing by the Secretary of the Corporation at least 15 days in advance of the meeting, such shareholder shall disclose to the Secretary, within ten days of such request, whether such person is the sole beneficial owner of the shares held of record by him, and, if not, the name and address of each other person known by the shareholder of record to claim or have a beneficial interest in such shares. 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 of the Corporation that information required to be set forth in a shareholder's notice of nomination which pertains to the nominee. If a shareholder seeks to nominate one or more directors, the Secretary shall appoint two inspectors, who shall not be affiliated with the Corporation, to determine whether the shareholder has complied with this Article IV(E). If the inspectors shall determine that the shareholder has not complied with this Article IV(E), the defective nomination shall be disregarded and the inspectors shall direct the Chairman of the meeting to declare at the meeting that such nomination was not made in accordance with the procedures prescribed by the Articles of Incorporation. E. Directors Elected by Preferred Shareholders. Notwithstanding anything in these Articles of Incorporation to the contrary, whenever the holders of any one or more classes or series of stock having a preference over the Common Stock as to dividends or upon liquidation shall have the right, voting separately as a class, to elect one or more directors of the Corporation, the provisions of these Articles of Incorporation (as they may be duly amended from time to time) fixing the rights and preferences of such preferred stock shall govern with respect to the nomination, election, term, removal, vacancies or other related matters with respect to such directors. 50 ARTICLE V BY-LAWS A. Adoption, Amendment and Repeal. The By-laws of the Corporation and of any provision thereof may be adopted only by two-thirds vote of all directors who constitute the Board of Directors. The By-laws and any provision thereof may be amended or repealed only by (1) a two-thirds vote of all directors who constitute the Board of Directors, or (2) the affirmative vote of the holders of at least eighty percent of that portion of the Total Voting Power, as defined in Article VII(C) hereof, voting together as a single class, that is present or represented at any regular or special meeting of shareholders, the notice of which meeting of shareholders expressly states that the proposed amendment or repeal is to be considered at the meeting. B. New Matters. Any purported amendment to the By-laws which would add thereto a matter not expressly covered in the By-laws prior to such purported amendment shall be deemed to constitute the adoption of a By-law provision and not an amendment to the By-laws. ARTICLE VI APPLICATION OF CERTAIN LAWS The Corporation hereby elects not to be governed by Sections 132, 133 and 134 of the Louisiana Business Corporation Law (La.R.S. 12:132, La.R.S. 12:133 and La.R.S. 12:134). ARTICLE VII SPECIAL SHAREHOLDER VOTING REQUIREMENTS A. Amendments. Unless approved by vote of at least two-thirds of all directors constituting the Board of Directors, Articles IV, V, VI, VII, VIII and X of the Articles of Incorporation may be amended only by the affirmative vote of not less than eighty percent of the Total Voting Power of the Corporation. Shareholders may, by the affirmative vote of a majority of the voting power present or represented at a meeting of shareholders, adopt any amendment to the Articles of Incorporation that does not affect any of such articles; provided, that shareholder approval shall not be required for any amendment authorized by Article III(B). B. Other Corporate Actions. If a vote of shareholders is required to authorize an agreement of merger or consolidation of the Corporation, the sale of all or substantially all of the assets of the Corporation or the voluntary dissolution of the Corporation, then (1) unless such action has been approved by vote of at least two-thirds of all directors constituting the Board of Directors, such action may be authorized only by the affirmative vote of eighty percent of the Total Voting Power of the Corporation and 51 (2) if any such action has been approved by vote of at least two-thirds of all directors who constitute the Board of Directors, such action may be authorized by the affirmative vote of a majority of the voting power present or represented at a meeting of shareholders. C. Total Voting Power. The term "Total Voting Power" means the total number of votes that shareholders, and holders of any bonds, debentures or other obligations granted voting rights by the Corporation pursuant to La.R.S. 12:75(H), are generally entitled to cast with respect to the election of directors or, if such term is used with reference to any other particular matter properly brought before the shareholders or such other holders for their consideration and vote, means the total number of such votes that are entitled to be cast with respect to such matter. ARTICLE VIII LIMITATION OF LIABILITY AND INDEMNIFICATION A. Limitation of Liability. No director or officer of the Corporation shall be liable to the Corporation or to its shareholders for monetary damages for breach of his fiduciary duty as a director or officer, provided that the foregoing provision shall not eliminate or limit the liability of a director or officer for (1) any breach of his duty of loyalty to the Corporation or its shareholders; (2) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (3) liability for unlawful distributions of the Corporation's assets to, or redemptions or repurchases of the Corporation's shares from shareholders of the Corporation, under and to the extent provided in La.R.S. 12:92(D); or (4) any transaction from which he derived an improper personal benefit. If, after the date hereof, the Louisiana Business Corporation Law is amended to authorize further elimination or limitation the personal liability of directors or officers, then the liability of a director or an officer of the Corporation shall be eliminated or limited to the fullest extent permitted by the Louisiana Business Corporation Law, as so amended. B. Indemnification. Subject to such limitations as may be determined by the Board of Directors (provided that no change in such limitations may adversely affect any claim to indemnification that arises prior to such change), the Corporation shall indemnify each of its directors to the full extent from time to time permitted by law, and may so indemnify each of its officers, against any expenses or costs, including attorney's fees, actually or reasonably incurred by him in connection with any threatened, pending or completed claim action, suit or proceeding, whether criminal, civil, administrative or investigative against such person or as to which he is involved solely as a witness or person required to give evidence. C. Authorization of Further Actions. The Board of Directors may (1) cause the Corporation to enter into contracts with its directors and officers providing for the limitation of liability set forth in this Article to the fullest extent permitted by law, (2) adopt By-laws or resolutions, or cause the Corporation to enter into contracts, providing for indemnification of directors and officers of the Corporation and other persons 52 (including but not limited to directors and officers of the Corporation's direct and indirect subsidiaries) to the fullest extent permitted by law and (3) cause the Corporation to exercise the powers set forth in La.R.S. 12:83F, notwithstanding that some or all of the members of the Board of Directors acting with respect to the foregoing may be parties to such contracts or beneficiaries of such By-laws or resolutions or the exercise of such powers. No repeal or amendment of any such By-laws or resolutions limiting the right to indemnification thereunder shall affect the entitlement of any person to indemnification whose claim thereto results from conduct occurring prior to the date of such repeal or amendment. D. Subsidiaries. The Board of Directors may cause the Corporation to approve for its direct and indirect subsidiaries limitation of liability and indemnification provisions comparable to the foregoing. E. Amendment. In addition to any other votes required by law or these Articles of Incorporation (and notwithstanding the fact that a lesser percentage may be specified by law or these Articles of Incorporation), the affirmative vote of the holders of at least 80% of the Total Voting Power shall be required to repeal this Article or to amend this Article so as to reduce the limitation of liability set forth herein or the rights to indemnification of any person or the powers of the Board of Directors provided in this Article, and any amendment or repeal of this Article shall not adversely affect any indemnification or limitation of liability of a director or officer of the Corporation under this Article with respect to any action or inaction occurring prior to the time of such amendment or repeal. ARTICLE IX REVERSION Cash, property or share dividends, shares issuable to shareholders in connection with a reclassification of stock, and the redemption price of redeemed shares, that are not claimed by the shareholders entitled thereto within one year after the dividend or redemption price became payable or the shares became issuable, despite reasonable efforts by the Corporation to pay the dividend or redemption price or deliver the certificates for the shares to such shareholders within such time, shall at the expiration of such time, revert in full ownership to the Corporation, and the Corporation's obligation to pay such dividend or redemption price or issue such shares, as the case may be, shall thereupon cease; provided, however, that the Board of Directors may, at any time, for any reason satisfactory to it, but need not, authorize (1) payment of the amount of any cash or property dividend or redemption price or (2) issuance of any shares, ownership of which has reverted to the Corporation pursuant to this Article, to the person or entity who or which would be entitled thereto had such reversion not occurred. 53 ARTICLE X SPECIAL MEETINGS OF SHAREHOLDERS A. Special meetings of shareholders, for any purpose or purposes, may be called in any manner set forth in the By-laws, provided that the power of shareholders as such to call or cause to be called special meetings shall be governed exclusively by paragraph B of this Article. B. At any time, upon the written request of any shareholder or group of shareholders holding in the aggregate at least a majority of the Total Voting Power, the Secretary of the Corporation shall call a special meeting of shareholders to be held at the registered office of the Corporation at such time as the Secretary may fix not less than 15 nor more than 60 days after the receipt of said request, and if the Secretary shall neglect or refuse to fix such time or to give notice of the meeting, the shareholder or shareholders making the request may do so.
