(2) Each series of Preferred Stock:

(a) may have such number of shares;

(b) may not have voting powers without the prior approval of the holders of a majority of the Common Stock except when dividends are in arrears for twelve (12) months;

(c) may be subject to redemption at such time or times and at such prices;

(d) may be entitled to receive dividends (which may be cumulative or noncumulative) at such rate or rates, on such conditions, from such date or dates, and at such times, and payable in preference to, or in relation to, the dividends payable on any other class or classes or series of stock;

(i) may have such other relative, participating optional or other special rights, and qualifications, limitations or restrictions thereof; all as shall be stated in said resolution or resolutions providing for the issue of such Preferred Stock. Except where otherwise set forth in the resolution or resolutions adopted by the Board of Directors providing for the issue of any series of Preferred Stock, the number of shares comprising such series may be increased or decreased (but not below the number of shares then outstanding) from time to time by like action of the Board of Directors.

(3) Shares of any series of Preferred Stock which have been redeemed (whether through the operation of a sinking fund or otherwise) or purchased by the corporation, or which, if convertible or exchangeable, have been converted into or exchanged for shares of stock of any other class or classes shall have the status of authorized and unissued shares of Preferred Stock and may be reissued as a part of the series of which they were originally a part or may be reclassified and reissued as part of a new series of Preferred Stock to be created by resolution or resolutions adopted by the Board of Directors providing for the issue of any series of Preferred Stock and to any filing required by law.

(4) Except as otherwise provided by law or by the resolution or resolutions of the Board of Directors providing for the issue of any series of the Preferred Stock, the Common Stock shall have the exclusive right to vote for the election of Directors and for all other purposes, each holder of the Common Stock being entitled to one vote for each share held.

Subject to all of the rights of the Preferred Stock or any series thereof, the holders of the Common Stock shall be entitled to receive, when, as and if declared by the Board of Directors, out of funds legally available therefor, dividends payable in cash, stock or otherwise.

Upon any liquidation, dissolution or winding up of the corporation, whether voluntary or involuntary, and after the holders of the Preferred Stock of each series shall have been paid in full the amounts to which they respectively shall be entitled or a sum sufficient for such payment in full shall have been set aside, the remaining net assets of the corporation shall be distributed pro rata to the holders of the Common Stock in accordance with their respective rights and interests, to the exclusion of the holders of the Preferred Stock.

(c) Effective as of May 15, 2006 (referred to as the “Effective Date”), each of the 80,580 shares of common stock of the corporation outstanding prior to the Effective Date, having a par value of Ten Dollars ($10.00) per share, were made equal to and changed into thirty (30) fully paid and nonassessable shares of common stock of the corporation having a par value of Thirty-Three and One/third Cents ($0.33-1/3) per share (the “Stock Split”), and were authorized to be issued under the Certificate of Formation, as previously amended. Certificates for shares of common stock having a par value of Thirty-Three and One/third Cents ($0.33-1/3) per share were issued in place and upon surrender of certificates of shares of the previously issued common stock having a par value of $10.00 per share. As of the Effective Date and thereafter, a certificate representing shares of common stock prior to the Stock Split were deemed to represent the number of new shares into which the old shares were convertible.

No stockholder of this corporation shall by reason of his holding shares of any class have any pre-emptive or preferential right to purchase or subscribe to any shares of any class of this corporation, now or hereafter to be authorized, or any notes, debentures, bond or other securities convertible into or carrying options or warrants to purchase shares of any class, now or hereafter to be authorized, whether or not the issuance of any such shares, or such notes, debentures, bonds or other securities, would adversely affect the dividend or voting rights of such stockholder, other than such rights, if any, as the Board of Directors, in its discretion from time to time may grant, and at such price as the Board of Directors in its discretion may fix; and the Board of Directors may issue shares of any class of this corporation, or any notes, debentures, bonds or other securities convertible into or carrying options or warrants to purchase shares of any class, without offering any such shares of any class, either in whole or in part, to the existing stockholders of any class.

A cumulative voting by the stockholders of the corporation at any election for directors is expressly prohibited. The shareholders entitled to vote for directors in such election shall be entitled to cast one vote per directorship for each share held, and no more.

ARTICLE FIVE

The corporation will not commence business until it has received for issuance of its shares consideration of the value of One Thousand Dollars ($1,000.00), consisting of money, labor done, or property actually received, which sum is not less than One Thousand ($1,000.00).

ARTICLE SEVEN

A director of the corporation shall not be personally liable to the corporation or its shareholders for monetary damages for an act or omission in such director’s capacity as a director, except for liability for (i) a breach of a director’s duty of loyalty to the corporation or its shareholders; (ii) an act or omission not in good faith or that involves intentional misconduct or a knowing violation of the law; (iii) a transaction from which a director received an improper benefit, whether or not the benefit resulted from an action taken within the scope of the director’s office; (iv) an act or omission for which the liability of a director is expressly provided by statute; or (v) an act related to an unlawful stock repurchase or payment of a dividend. If the laws of the State of Texas are hereafter amended to authorize corporate action further eliminating or limiting the personal liability of a director of the corporation, then the liability of a director of the corporation shall thereupon automatically be eliminated or limited to the fullest extent permitted by such laws. Any repeal or modification of this Article Seven by the shareholders of the corporation shall not adversely affect any right or protection of a director existing at the time of such repeal or modification with respect to events or circumstances occurring or existing prior to such time.
