Any decision or act of the Board within the scope of its power and authority granted hereunder shall control and shall bind the Company.

Section 5.4 Reliance by Third Parties. Persons dealing with the Company are entitled to rely conclusively upon the power and authority of the Board herein set forth.

Section 5.5 Limitation on Duties and Liabilities.

The foregoing is not intended to expand in any manner the duties (including any fiduciary duties), whether at law or in equity, of any Manager or Member.

ARTICLE VI

OFFICERS

The Managers may designate one or more persons to be officers of the Company. Officers are not "managers," as that term is used in the BOC. Any officers who are so designated shall have such titles and authority and perform such duties as the Managers may delegate to them. Any officer may be removed as such, either with or without cause, by the Managers. Designation of an officer shall not of itself create contract rights.

ARTICLE VII

DISTRIBUTIONS AND CAPITAL CONTRIBUTIONS

Section 7.1 The Company may, from time to time, make distributions to one or more of the Members of the Company and without obligation to make a similar distribution to all other Members,

provided that such a distribution is permitted by all lending agreements to which the Company is then a party. In the event that a distribution is made to one or more but less than all of the Members of the Company, the capital accounts of such Member or Members receiving such a distribution shall be reduced by an amount equal to the distribution.

Section 7.2 Any Member of the Company may, subject to the approval of the Company, make a capital contribution to the Company. The making of such a capital contribution shall not obligate any other Member of the Company to make an equal or ratable capital contribution. In the event that a Member makes a capital contribution to the Company, such Member's capital account shall be increased by the amount of such capital contribution.

ARTICLE VIII

INDEMNIFICATION

Section 8.1 Certain Terms. For purposes of this Article VIII, "Parent Company" shall mean and refer to the Company's ultimate parent company with common stock listed on the New York Stock Exchange or traded through The NASDAQ Stock Market. For purposes of this Article VIII, Managers shall, for all purposes, be treated in the same manner as Directors of the Parent Company in the event that the Parent Company is a corporation.

Section 8.2 Indemnification. Subject in all respects to any requirements or limitations contained in the BOC, the Company shall indemnify and hold harmless its Managers, officers and, if applicable, employees and other agents to the same extent, in the same manner and subject to the same rights, terms, conditions and procedures (including, without limitation, with respect to the advancement of expenses) as such categories of persons would be indemnified and held harmless by the Parent Company pursuant to the Bylaws, Certificate of Incorporation or other relevant charter documents of the Parent Company (the "Parent Company Charter Documents"); provided, that if at any time the Company does not have a Parent Company with common stock listed on the New York Stock Exchange or traded through The NASDAQ Stock Market, the Company shall during such time provide indemnification and advancement of expenses to its Managers, officers, employees and other agents to the maximum extent permitted by the BOC.

Section 8.3 Severability. If any provision or provisions of this Article VIII or any provision referenced from the Parent Company Charter Documents shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (i) the validity, legality and enforceability of the remaining provisions (including, without limitation, each portion of any paragraph containing any such provision held to be invalid, illegal or unenforceable, that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and (ii) to the fullest extent possible, the provisions (including, without limitation, each such portion of a paragraph containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by the provision or provisions held invalid, illegal or unenforceable.

ARTICLE IX

MISCELLANEOUS

Section 9.1 Amendments. This Agreement may be amended by, and only by, a written instrument executed by each of the Members.

Section 9.2 Governing Law and Severability. This Agreement shall be governed by and construed in accordance with the laws of the State of Texas without giving effect to the principles of conflicts of law. In particular, this Agreement shall be construed to the maximum extent possible to comply with all terms and conditions of the BOC. If it shall be determined by a court of competent jurisdiction that any provisions or wording of this Agreement shall be invalid or unenforceable under the BOC or other

applicable law, such invalidity or unenforceability shall not invalidate the entire Agreement. In that case, this Agreement shall be construed so as to limit any term or provision so as to make it enforceable or valid within the requirements of applicable law, and, in the event such term or provision cannot be so limited, this Agreement shall be construed to omit such invalid or unenforceable term or provision.
