Not applicable. Item 5. Interests of Named Experts and Counsel. Not applicable. Item 6. Indemnification of Directors and Officers. The Company, a Texas corporation, is empowered by Article 2.02-1 of the Texas Business Corporation Act (the "TBCA"), subject to the procedures and limitations stated therein, to indemnify certain persons, including any person who was, is or is threatened to be made a named defendant or respondent in a threatened, pending, or completed action, suit or proceeding because the person is or was a director or officer, against judgments, penalties (including excise and similar taxes), fines, settlements and reasonable expenses (including court costs and attorneys' fees) actually incurred by the person in connection with the threatened, pending, or completed action, suit or proceeding. The Company is required by Article 2.02-1 to indemnify a director or officer against reasonable expenses (including court costs and attorneys' fees) incurred by such person in connection with a threatened, pending, or completed action, suit or proceeding in which such person is a named defendant or respondent because such person is or was a director or officer if such person has been wholly successful, on the merits or otherwise, in the defense of the action, suit or proceeding. Article 2.02-1 provides that indemnification pursuant to its provisions is not exclusive of other rights of indemnification to which a person may be entitled under the corporation's articles of incorporation or any bylaw, agreement, vote of shareholders or disinterested directors, or otherwise. The Second Amended and Restated Bylaws, as amended, of the Company provide for indemnification by the Company of its directors and officers to the fullest extent permitted by the TBCA. In addition, the Company has, pursuant to Article 1302-7.06 of the Texas Miscellaneous Corporation Laws Act, provided in its Articles that, a director of the Company shall not be liable to the Company or its shareholders for monetary damages for an act or omission in a director's capacity as director of the Company. Furthermore, the Company has entered into individual indemnification agreements with each director of the Company that contractually obligate the Company to provide indemnification to the directors for liabilities such directors may incur in the performance of their duties and insurance or self-insurance in lieu thereof. Item 7. Exemption from Registration Claimed. Not applicable. Item 8. Exhibits. See Index to Exhibits, attached hereto on page I-1. Item 9. Undertakings. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. The undersigned registrant hereby undertakes: (1) That, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (2) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (2)(i) and (2)(ii) do not apply if the registration statement is on Form S-3, Form S-8 or Form F-3, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement. (3) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (4) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Dallas, State of Texas on this 27th day of April, 1999.

ARTICLE II SHAREHOLDERS SECTION 1. PLACE OF MEETINGS. All meetings of the shareholders shall be held at the principal place of business of the Corporation or at such other place within or without the State of Texas as shall be specified or fixed in the notices or waivers of notice thereof; provided that any or all shareholders may participate in any such meeting by means of conference telephone or similar communications equipment pursuant to Article II, Section 12 of these bylaws. SECTION 2. QUORUM; REQUIRED VOTE FOR SHAREHOLDER ACTION; ADJOURNMENT OF MEETINGS. (a) Quorum. A quorum shall be present at a meeting of shareholders if the holders of a majority of the shares entitled to vote are represented at the meeting in person or by proxy. (b) Voting on Matters Other than the Election of Directors. With respect to any matter, other than the election of directors or a matter for which the affirmative vote of the holders of a specified portion of the shares entitled to vote is required by the TBCA, the affirmative vote of the holders of a majority of the shares entitled to vote on that matter and represented in person or by proxy at a meeting of shareholders at which a quorum is present shall be the act of the shareholders, unless otherwise provided in the Amended and Restated Articles of Incorporation or these bylaws in accordance with the TBCA. (c) Voting in the Election of Directors. Subject to any agreements among shareholders now or hereafter existing regarding the election of directors, directors shall be elected only if the director receives the vote of the holders of a majority of the shares entitled to vote in the election of directors. (d) Adjournment. Notwithstanding the other provisions of the Amended and Restated Articles of Incorporation or these bylaws, the chairman of the meeting or the holders of a majority of the shares entitled to vote that are represented in person or by proxy at any meeting of shareholders, whether or not a quorum is present, shall have the power to adjourn such meeting from time to time, without any notice other than announcement at the meeting of the time and place of the holding of the adjourned meeting.

Such writing, which may be in counterparts, shall be manually executed if practicable; provided, however, that if circumstances so require, effect shall be given to written consent transmitted by telegraph, telex, telecopy or similar means of visual data transmission. Meetings of the shareholders of the Corporation may be conducted by means of conference telephone or similar communications equipment whereby all persons participating in the meeting can hear and speak to each other.

If no record date has been fixed by the Board of Directors and the prior action of the Board of Directors is not required by law or these bylaws, the record date for determining shareholders entitled to consent to action in writing without a meeting shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation by delivery to its registered office, its principal place of business, or an officer or agent of the Corporation having custody of the books in which proceedings of meetings of shareholders are recorded. Delivery shall be by hand or by certified or registered mail, return receipt requested.

Notice of any special meeting shall be given at least two days prior thereto by written notice delivered personally or mailed to each director at his business address, or by telecopy or similar means of visual data transmission.

Any directorship to be filled by reason of an increase in the number of directors may be filled (a) by the Board of Directors for a term of office continuing only until the next election of one or more directors by the shareholders; PROVIDED, HOWEVER, that during the period between any two successive annual meetings of shareholders, the Board of Directors may not fill more than two such directorships; or (b) by election at an annual or special meeting of shareholders entitled to vote in the election of such directors called for that purpose. SECTION 8. REMOVAL.

Any action permitted or required by the TBCA, the Amended and Restated Articles of Incorporation or these bylaws to be taken at a meeting of the Board of Directors or any committee designated by the Board of Directors may be taken without a meeting if a consent in writing, setting forth the action to be taken, is signed by all the members of the Board of Directors or committee, as the case may be. Such consent shall have the same force and effect as a unanimous vote at a meeting and may be stated as such in any document or instrument filed with the Secretary of State, and the execution of such consent shall constitute attendance or presence in person at a meeting of the Board of Directors or any such committee, as the case may be. Subject to the requirement of the TBCA or these bylaws for notice of meetings, members of the Board of Directors, or members of any committee designated by the Board of Directors, may participate in and hold a meeting of the Board of Directors or any committee of directors, as the case may be, by means of a conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and participation in such meeting shall constitute attendance and 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 wound that the meeting is not lawfully called or convened.

The rights granted pursuant to this Article VI shall be deemed contract rights, and no amendment, modification or repeal of this Article VI shall have the effect of limiting or denying any such rights with respect to actions taken or proceedings arising prior to any such amendment, modification or repeal. It is expressly acknowledged that the indemnification provided in this Article VI could involve indemnification for negligence or under theories of strict liability. SECTION 2. ADVANCE PAYMENT. The right to indemnification conferred in this Article VI shall include the right to be paid or reimbursed by the Corporation the reasonable expenses incurred by a person of the type entitled to be indemnified under Section 1 who was, is or is threatened to be made a named defendant or respondent in a proceeding in advance of the final disposition of the proceeding and without any determination as to the person's ultimate entitlement to indemnification; provided, however, that the payment of such expenses incurred by any such person in advance of the final disposition of a proceeding, shall be made only upon delivery to the Corporation of a written affirmation by such director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification under this Article VI and a written undertaking, by or on behalf of such person, to repay all amounts so advanced if it shall ultimately be determined that such indemnified person is not entitled to be indemnified under this Article VI or otherwise. SECTION 3. INDEMNIFICATION OF EMPLOYEES AND AGENTS. The Corporation, by adoption of a resolution of the Board of Directors, may (but shall not be required to) indemnify and advance expenses to an employee or agent of the Corporation to the same extent and subject to the same conditions under which it may indemnify and advance expenses to directors and officers under this Article VI; and, the Corporation may (but shall not be required to) indemnify and advance expenses to persons who are not or were not directors, officers, employees or agents of the Corporation but who are or were serving at the request of the Corporation as a director, officer, partner, venturer, proprietor, trustee, employee, agent or similar functionary of another foreign or domestic corporation, partnership, joint venture, sole proprietorship, trust, employee benefit plan and or other enterprise against any liability asserted against that person and incurred by that person in such a capacity or arising out of such individual's status as such a person to the same extent that it may indemnify and advance expenses to directors under this Article VI. SECTION 4. APPEARANCE AS A WITNESS. Notwithstanding any other provision of this Article VI, the Corporation may pay or reimburse expenses incurred by a director or officer in connection with his or her appearance as a witness or other participation in a proceeding at a time when he or she is not a named defendant or respondent in the proceeding. SECTION 5. NONEXCLUSIVITY OF RIGHTS. The right to indemnification and the advancement and payment of expenses conferred in this Article VI shall not be exclusive of any other right which a director or officer or other person indemnified pursuant to Section 3 of this Article VI may have or hereafter acquire under any law (common or statutory), provision of the Amended and Restated Articles of Incorporation or these bylaws, agreement, vote of shareholders or disinterested directors or otherwise. SECTION 6. INSURANCE.

SECTION 7. SHAREHOLDER NOTIFICATION. To the extent required by law, any indemnification of or advance of expenses to a director or officer in accordance with this Article VI shall be reported in writing to the shareholders with or before the notice or waiver of notice of the next shareholder's meeting or with or before the next submission to shareholders of a consent to action without a meeting. SECTION 8. SAVINGS CLAUSE. If this Article VI or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify and hold harmless each director, officer or any other person indemnified pursuant to this Article VI as to costs, charges and expenses (including attorneys' fees), judgments, fines and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative to the full extent permitted by any applicable portion of this Article VI that shall not have been invalidated and to the fullest extent permitted by applicable law. ARTICLE VII CAPITAL STOCK SECTION 1. CERTIFICATES OF STOCK. The certificates for shares of the capital stock of the Corporation shall be in such form, consistent with that required by law and the Amended and Restated Articles of Incorporation, as shall be approved by the Board of Directors. The Chairman of the Board, President or a Vice President (if any) shall cause to be issued to each shareholder one or more certificates, which shall be signed by (a) one of the Chairman of the Board, President, or a Vice President and (b) one of the Secretary, an Assistant Secretary, the Treasurer or an Assistant Treasurer certifying the number of shares (and, if the stock of the Corporation shall be divided into classes or series, the class and series of such shares) owned by such shareholder in the Corporation; provided however, that any or all of the signatures on the certificate may be facsimile. If the Board of Directors shall have provided for a seal, such certificates shall bear such seal or a facsimile thereof. The stock record books and the blank stock certificate books shall be kept by the Secretary, or at the office of such transfer agent or transfer agents as the Board of Directors may from time to time by resolution determine. In case any officer, transfer agent or registrar who shall have signed or have ceased to be such officer, transfer agent or registrar before such certificate is issued by the Corporation, such certificate may nevertheless be issued by the Corporation with the same effect as if such person were such officer, transfer agent or registrar at the date of issue. The stock certificates shall be consecutively numbered and shall be entered in the books of the Corporation as they are issued and shall exhibit the holder's name and number of shares. SECTION 2. TRANSFER OF SHARES. The shares of stock of the Corporation shall be transferable only on the books of the Corporation by the holders thereof in person or by their duly authorized attorneys or legal representatives, upon surrender and cancellation of certificates for a like number of shares (or upon compliance with the provisions of Section 4 of this Article VII, if applicable). Upon such surrender to the Corporation or a transfer agent of the Corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignment or authority to transfer (or upon compliance with the provisions of Section 4 of this Article VII, if applicable) and of compliance with any transfer restrictions applicable thereto contained in an agreement to which the Corporation is a party or of which the Corporation has knowledge by reason of legend with respect thereto placed on any such surrendered stock certificate, it shall be the duty of the Corporation to issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books. SECTION 3. REGULATIONS REGARDING CERTIFICATES. The Board of Directors shall have the power and authority to make all such rules and regulations as they may deem expedient concerning the issuance, transfer and registration or the replacement of certificates for shares of capital stock of the Corporation. SECTION 4. LOST, STOLEN, DESTROYED OR MUTILATED CERTIFICATES. The Board of Directors may determine the conditions upon which a new certificate of stock may be issued in place of a certificate that is alleged to have been lost, stolen, destroyed or mutilated; and may, in its discretion, require the owner of such certificate or his legal representative to give bond, with sufficient surety, to indemnify the Corporation and each transfer agent and registrar against any and all losses or claims which may arise by reason of the issuance of a new certificate in the place of the one so lost, stolen, destroyed or mutilated. ARTICLE VIII MISCELLANEOUS PROVISIONS SECTION 1. FISCAL YEAR. The fiscal year of the Corporation shall be such as established from time to time by the Board of Directors. SECTION 2. CORPORATE SEAL. The Board of Directors may provide a suitable seal, containing the name of the Corporation. The Secretary shall have charge of the seal (if any). If and when so directed by the Board of Directors, duplicates of the seal may be kept and used by the Treasurer, if any, or by any Assistant Secretary or Assistant Treasurer. SECTION 3.

Whenever notice is required to be given by law, the Amended and Restated Articles of Incorporation or these bylaws, a written waiver thereof, signed by the person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. SECTION 4. RESIGNATIONS. Any director, member of a committee or officer may resign at any time. Such resignation shall be made in writing and shall take effect at the time specified therein, or if no time be specified, at the time of its receipt by the chief executive officer or Secretary. The acceptance of a resignation shall not be necessary to make it effective, unless expressly so provided in the resignation. SECTION 5. FACSIMILE SIGNATURES.

Such records shall contain the names and addresses of all past and current shareholders of the Corporation and the number and class of shares issued by the Corporation held by each of them.
