The authority of the Board of Directors with respect to such series of Preference Stock shall include, but not be limited to, determination of the following: (1) the distinctive designation and number of shares of that series; (2) the rate of dividend (or the method of calculation thereof) payable with respect to shares of that series, the dates, terms and other conditions upon which such dividends shall be payable, and the relative rights of priority of such dividends to dividends payable on any other class or series of capital stock of the Company; provided, however, that the relative rights of priority of that series must rank junior to the relative rights of priority of Preferred Stock; (3) the nature of the dividend payable with respect to shares of that series as cumulative, noncumulative or partially cumulative, and if cumulative or partially cumulative, from which date or dates and under what circumstances; (4) whether shares of that series shall be subject to redemption, and, if made subject to redemption, the times, prices, rates, adjustments and other terms and conditions of such redemption (including the manner of selecting shares of that series for redemption if fewer than all shares of such series are to be redeemed); (5) the rights of the holders of shares of that series in the event of voluntary or involuntary liquidation, dissolution or winding up of the Company (which rights may be different if such action is voluntary than if it is involuntary), including the relative rights of priority in such event as to the rights of the holders of any other class or series of capital stock of the Company; provided, 2 3 however, that the relative rights of priority of that series must rank junior to the relative rights of priority of Preferred Stock; (6) the terms, amounts and other conditions of any sinking or similar purchase or other fund provided for the purchase or redemption of shares of that series; (7) whether shares of that series shall be convertible into or exchangeable for shares of capital stock or other securities of the Company or of any other corporation or entity, and, if provision be made for conversion or exchange, the times, prices, rates, adjustments, and other terms and conditions of such conversion or exchange; (8) the extent, if any, to which the holders of shares of that series shall be entitled (in addition to any voting rights provided by law) to vote as a class or otherwise with respect to the election of directors or otherwise; (9) the restrictions and conditions, if any, upon the issue or reissue of any additional Preference Stock ranking on a parity with or prior to shares of that series as to dividends or upon liquidation, dissolution or winding up; (10) any other repurchase obligations of the Company, subject to any limitations of applicable law; and (11) any other designations, preferences, limitations or relative rights of shares of that series. Any of the designations, preferences, limitations or relative rights (including the voting rights) of any series of Preference Stock may be dependent on facts ascertainable outside these Articles of Incorporation.

Dividends. Dividends may be paid on either or both classes of Common Stock, as the Board of Directors shall from time to time determine, out of any assets of the Company available for such dividends after full cumulative dividends on all outstanding shares of capital stock of all series ranking senior to the Common Stock in respect of dividends and liquidation rights (referred to in this Division D as "stock ranking senior to the Common Stock") have been paid, or declared and a sum sufficient for the payment thereof set apart, for all past quarterly dividend periods, and after or concurrently with making payment of or provision for dividends on the stock ranking senior to the Common Stock for the then current quarterly dividend period. 3 4 2. Distribution of Assets. In the event of any liquidation, dissolution or winding up of the Company, or any reduction or decrease of its capital stock resulting in a distribution of assets to the holders of its Common Stock, after there shall have been paid to or set aside for the holders of the stock ranking senior to the Common Stock the full preferential amounts to which they are respectively entitled, the holders of the Common Stock shall be entitled to receive, pro rata, all of the remaining assets of the Company available for distribution to its stockholders. The Board of Directors, by vote of a majority of the members thereof, may distribute in kind to the holders of the Common Stock such remaining assets of the Company, or may sell, transfer or otherwise dispose of all or any of the remaining property and assets of the Company to any other corporation or other purchaser and receive payment thereof wholly or partly in cash or property, and/or in stock of any such corporation, and/or in obligations of such corporation or other purchaser, and may sell all or any part of the consideration received therefor and distribute the same or the proceeds thereof to the holders of the Common Stock. 3.

ARTICLE FIVE The third amendment creates a new ARTICLE X of the Restated Articles of Incorporation and the full text of such new Article is as follows: 4 5 "ARTICLE X To the extent permitted by applicable law and except as expressly provided in the relative rights and preferences of any series of Preference Stock, the vote of stockholders required for approval of any action that is recommended to stockholders by the Board of Directors and for which applicable law requires a stockholder vote, including without limitation (1) any such plan of merger, consolidation or exchange, (2) any such disposition of assets, (3) any such dissolution of the Company, and (4) any such amendment of these Articles of Incorporation, shall, if a greater vote of stockholders is provided for by the Texas Business Corporation Act or other applicable law, instead be the affirmative vote of the holders of a majority of the outstanding shares entitled to vote thereon, unless any class or series of shares is entitled to vote as a class thereon, in which event the vote required shall be the affirmative vote of the holders of a majority of the outstanding shares within each class or series of shares entitled to vote thereon as a class and at least a majority of the outstanding shares otherwise entitled to vote thereon; provided, however, that the voting rights of the holders of Preferred Stock are not affected by this ARTICLE X. The foregoing shall not apply to any action or stockholder vote authorized or required by any addition, amendment or modification to applicable law that becomes effective after November 30, 1996 if and to the extent a bylaw adopted by the Board of Directors or the stockholders so provides. Any repeal, amendment or modification of any such bylaw so adopted shall require the same vote of stockholders as would be required to approve the action or vote subject to such bylaw had the first sentence of this Article X not applied to such action or vote." ARTICLE SIX The number of shares of the Corporation outstanding at the time of such adoption was 3,805,497 (3,804,397 shares of Preferred Stock, 1,000 shares of Class A Common Stock and 100 shares of Class B Common Stock); and the number of shares entitled to vote thereon was 1,100 (Class A Common Stock and Class B Common Stock).

IN WITNESS WHEREOF, the Corporation has caused these Articles of Amendment to the Articles of Incorporation to be duly executed as of the 3rd day of December, 1996.
