In rendering such opinion, such counsel may state that its opinion is limited to matters governed by the Federal laws of the United States of America, the laws of the States of Texas and New York and the General Corporation Law of the State of Delaware. Such counsel shall also have furnished to the Underwriter a written statement, addressed to the Underwriter and dated such Delivery Date, in form and substance satisfactory to the Underwriter, to the effect that (x) such counsel has acted as counsel to the Company on a regular basis (although the Company is also represented by its General Counsel), has acted as counsel to the Company in connection with previous financing transactions and has acted as counsel to the Company in connection with the preparation of the Registration Statement, and (y) based on the foregoing, no facts have come to the attention of such counsel which lead it to believe that (I) the Registration Statement, as of the Effective Date, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or that the Prospectus or the Prospectus Supplement contains any untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, 17 not misleading or (II) any document incorporated by reference in the Prospectus Supplement, when they became effective or were filed with the Commission, as the case may be, contained in the case of a registration statement which became effective under the Securities Act, any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or, in the case of other documents which were filed under the Exchange Act with the Commission, an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The foregoing opinion and statement may be qualified by a statement to the effect that such counsel does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Prospectus or the Prospectus Supplement except for the statements made in the Prospectus under the section referenced in clause (iii) above, insofar as such statements relate to the Stock and concern legal matters. The opinions requested in subsection (d)(i) and (d)(iii) above with respect to the Significant Subsidiaries and options, warrants or convertible debentures outstanding, in subsection (d)(iv) above with respect to legal proceedings, in subsection (d)(vii) above with respect to contracts, in subsection (d)(ix) above with respect to no conflicts, breaches, violations, defaults or creation or imposition of liens, charges, claims or encumbrances and in subsection (d)(x) above with respect to registration rights may be rendered by John Buvens, Senior Vice President, Legal of the Company. The opinion rendered by Mr. Buvens shall also include a statement covering the matters set forth under clause (y) in the immediately preceding paragraph. (e) The Underwriter shall have received from Vinson & Elkins L.L.P., counsel for the Underwriter, such opinion or opinions, dated such Delivery Date, with respect to the issuance and sale of the Stock, the Registration Statement, the Prospectus, the Prospectus Supplement and other related matters as the Underwriter may reasonably require, and the Company shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters. (f) At the time of execution of this Agreement, the Underwriter shall have received from Deloitte & Touche LLP a letter, in form and substance satisfactory to the Underwriter, addressed to the Underwriter and dated the date hereof (i) confirming that they are independent public accountants within the meaning of the Securities Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission, (ii) stating, as of the date hereof (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Prospectus Supplement, as of a date 18 not more than five days prior to the date hereof), the conclusions and findings of such firm with respect to the financial information and other matters ordinarily covered by accountants' "comfort letters" to underwriters in connection with registered public offerings. (g) With respect to the letter of Deloitte & Touche LLP referred to in the preceding paragraph and delivered to the Underwriter concurrently with the execution of this Agreement (the "initial letter"), the Company shall have furnished to the Underwriter a letter (the "bring-down letter") of such accountants, addressed to the Underwriter and dated such Delivery Date, (i) confirming that they are independent public accountants within the meaning of the Securities Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission, (ii) stating, as of the date of the bring-down letter (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Prospectus Supplement, as of a date not more than five days prior to the date of the bring-down letter), the conclusions and findings of such firm with respect to the financial information and other matters covered by the initial letter and (iii) confirming in all material respects the conclusions and findings set forth in the initial letter. (h) The Company shall have furnished to the Underwriter a certificate, dated such Delivery Date, of its Chairman of the Board, its President or a Vice President and its Chief Financial Officer stating that: (i) The representations, warranties and agreements of the Company in Section 1 are true and correct as of such Delivery Date; the Company has complied with all its agreements contained herein; and the conditions set forth in Sections 7(a) and 7(i) have been fulfilled; and (ii) They have carefully examined the Registration Statement, the Prospectus and the Prospectus Supplement and, in their opinion (A) as of the Effective Date, the Registration Statement, the Prospectus and the Prospectus Supplement did not include any untrue statement of a material fact and did not omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and (B) since the Effective Date no event has occurred which should have been set forth in a supplement or amendment to the Registration Statement or the Prospectus. (i) Neither the Company nor any of its subsidiaries shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Prospectus Supplement any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Prospectus Supplement or (ii) 19 since such date there shall not have been any change in the capital stock or long-term debt of the Company or any of its subsidiaries or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, stockholders' equity or results of operations of the Company and its subsidiaries, otherwise than as set forth or contemplated in the Prospectus Supplement (and except for shares of Common Stock issued in connection with exercises of options and conversions of convertible debentures granted under the Company's existing employee benefit plans, qualified stock option plans or other employee compensation plans), the effect of which, in any such case described in clause (i) or (ii), is, in the judgment of the Underwriter, so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Stock being delivered on such Delivery Date on the terms and in the manner contemplated in the Prospectus Supplement. (j) Subsequent to the execution and delivery of this Agreement (i) no downgrading shall have occurred in the rating accorded the Company's debt securities by any "nationally recognized statistical rating organization", as that term is defined by the Commission for purposes of Rule 436(g)(2) of the Rules and Regulations and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company's debt securities. (k) Subsequent to the execution and delivery of this Agreement there shall not have occurred any of the following: (i) trading in securities generally on the New York Stock Exchange or the American Stock Exchange or in the over-the-counter market, or trading in any securities of the Company on any exchange or in the over-the-counter market, shall have been suspended or the settlement of such trading shall have been materially disrupted or minimum prices shall have been established on any such exchange or such market by the Commission, by such exchange or by any other regulatory body or governmental authority having jurisdiction, (ii) a banking moratorium shall have been declared by Federal or state authorities, (iii) the United States shall have become engaged in hostilities, there shall have been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United States or (iv) there shall have occurred such a material adverse change in general economic, political or financial conditions, including without limitation as a result of terrorist activities after the date hereof (or the effect of international conditions on the financial markets in the United States shall be such), as to make it, in the judgment of the Underwriter, impracticable or inadvisable to proceed with the public offering or delivery of the Stock being delivered on such Delivery Date on the terms and in the manner contemplated in the Prospectus Supplement. (l) The New York Stock Exchange, Inc. shall have approved the Stock for listing, subject only to official notice of issuance. 20 All opinions, letters, evidence and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Underwriter. 8. Indemnification and Contribution. (a) The Company shall indemnify and hold harmless the Underwriter, its officers and employees and each person, if any, who controls any Underwriter within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Stock), to which that Underwriter, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus Supplement, the Prospectus Supplement, the Registration Statement or the Prospectus or in any amendment or supplement thereto, (ii) the omission or alleged omission to state in any Preliminary Prospectus Supplement, the Prospectus Supplement, the Registration Statement or the Prospectus, or in any amendment or supplement thereto, or in any Blue Sky Application any material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any act or failure to act or any alleged act or failure to act by the Underwriter in connection with, or relating in any manner to, the Stock or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (i) or (ii) above (provided that the Company shall not be liable under this clause (iii) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by the Underwriter through its gross negligence or willful misconduct), and shall reimburse the Underwriter and each such officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Underwriter, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus Supplement, the Prospectus Supplement, the Registration Statement or the Prospectus, or in any such amendment or supplement, in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company through the Underwriter by or on behalf of any Underwriter specifically for inclusion therein 21 which information consists solely of the information specified in Section 8(e). The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to any Underwriter or to any officer, employee or controlling person of the Underwriter; provided, however, that with respect to any untrue statement or omission made in any Preliminary Prospectus Supplement, the indemnity agreement contained in this Section 8(a) shall not inure to the benefit of the Underwriter from whom the person asserting any such losses, claims, damages or liabilities purchased the Stock concerned if, to the extent such sale was an initial sale by the Underwriter and any such loss, claim, damage or liability of the Underwriter is a result of the fact that both (A) a copy of the Prospectus was not sent or given to such person at or prior to the time of the written confirmation of the sale of such Stock to such person, and (B) the untrue statement or omission in any Preliminary Prospectus Supplement was corrected in the Prospectus Supplement; provided further, however, that this limitation shall have no effect unless the Company has complied with its obligation under Section 5(c) of this Agreement and the Underwriter has a legal obligation to deliver a Prospectus Supplement to the person asserting any such losses, claims, damages or liabilities. (b) The Underwriter shall indemnify and hold harmless the Company, its officers who have signed the Registration Statement, each of its directors, and each person, if any, who controls the Company within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company or any such director, officer or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained (A) in any Preliminary Prospectus Supplement, the Prospectus Supplement, the Registration Statement or the Prospectus or in any amendment or supplement thereto, or (B) in any Blue Sky Application or (ii) the omission or alleged omission to state in any Preliminary Prospectus Supplement, the Prospectus Supplement, the Registration Statement or the Prospectus, or in any amendment or supplement thereto, or in any Blue Sky Application any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning the Underwriter furnished to the Company by or on behalf of that Underwriter specifically for inclusion therein, and shall reimburse the Company and any such director, officer or controlling person for any legal or other expenses reasonably incurred by the Company or any such director, officer or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability which the 22 Underwriter may otherwise have to the Company or any such director, officer, employee or controlling person. (c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent it has been materially prejudiced by such failure and, provided further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Underwriter shall have the right to employ counsel to represent the Underwriter and its officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriter against the Company under this Section 8 if, in the reasonable judgment of the Underwriter, it is advisable for the Underwriter and those officers, employees and controlling persons to be jointly represented by separate counsel, and in that event the fees and expenses of such separate counsel shall be paid by the Company, it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to the fees and expenses of any local counsel that may be retained for the action) for all such indemnified parties. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding, or (ii) be liable for any settlement of any such action effected without its written consent 23 (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. (d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other from the offering of the Stock or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriter on the other with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Stock purchased under this Agreement (before deducting expenses) received by the Company on the one hand, and the total underwriting discounts and commissions received by the Underwriter with respect to the shares of the Stock purchased under this Agreement on the other hand, bear to the total gross proceeds from the offering of the shares of the Stock under this Agreement, in each case as set forth on the cover page of the Prospectus Supplement. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriter, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 8 were to be determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8 shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), the Underwriter shall not be required to contribute any amount in excess of the 24 amount by which the total price at which the Stock underwritten by it and distributed to the public was offered to the public exceeds the amount of any damages which the Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. (e) The Underwriter confirms and the Company acknowledges that the statements with respect to (i) the public offering of the Stock by the Underwriter and the over-allotment option set forth on the cover page of, (ii) the identity of the Underwriter, the statement as to the Underwriter's participation in the sale of Stock, and the Underwriter's proposal to offer the Stock to the public under the caption "Underwriting" in, and (iii) the paragraphs addressing the commissions and expenses, over-allotment option, and affiliates under the caption "Underwriting" in, the Prospectus Supplement are correct and constitute the only information concerning the Underwriter furnished in writing to the Company by or on behalf of the Underwriter specifically for inclusion in the Registration Statement, the Prospectus and the Prospectus Supplement. 9. Default by Underwriter. If, on any Delivery Date, the Underwriter defaults in the performance of its obligations under this Agreement, this Agreement (or, with respect to the Second Delivery Date, the obligation of the Underwriter to purchase, and of the Company to sell, the Option Stock) shall terminate. Nothing contained herein shall relieve the Underwriter of any liability it may have to the Company for damages caused by its default. 10. Termination. The obligations of the Underwriter hereunder may be terminated by the Underwriter by notice given to and received by the Company prior to delivery of and payment for the Firm Stock if, prior to that time, any of the events described in Sections 7(i), 7(j) or 7(k), shall have occurred or if the Underwriter shall decline to purchase the Stock for any reason permitted under this Agreement. 11. Reimbursement of Underwriter's Expenses. If the Company shall fail to tender the Stock for delivery to the Underwriter by reason of any failure, refusal or inability on the part of the Company to perform any agreement on its part to be performed, or because any other condition of the Underwriter's obligations hereunder required to be fulfilled by the Company is not fulfilled, the Company will reimburse the Underwriter for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriter in connection with this Agreement and the proposed purchase of the Stock, and upon demand the Company shall pay the full amount thereof to the Underwriter. If this Agreement is terminated pursuant to Section 9 by reason of the default of the Underwriter, the Company shall not be obligated to reimburse the Underwriter on account of the Underwriter's expenses. 12. Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and: 25 (a) if to the Underwriter, shall be delivered or sent by mail, telex or facsimile transmission to Lehman Brothers Inc., 1285 Avenue of the Americas, 13th Floor, New York, New York 10019, Attention: Syndicate Registration Department (Fax: 212-526-0943), with a copy, in the case of any notice pursuant to Section 8(c), to the Director of Litigation, Office of the General Counsel, Lehman Brothers Inc., 399 Park Avenue, 10th Floor, New York, NY 10022; (b) if to the Company, shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: General Counsel (Fax: (713) 960-7658); Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof. 13.

This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that (A) the representations, warranties, indemnities and agreements of the Company contained in this Agreement shall also be deemed to be for the benefit of the person or persons, if any, who control the Underwriter within the meaning of Section 15 of the Securities Act and (B) the indemnity agreement of the Underwriter contained in Section 8(b) of this Agreement shall be deemed to be for the benefit of directors of the Company, officers of the Company who have signed the Registration Statement and any person controlling the Company within the meaning of Section 15 of the Securities Act. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 13, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. 14. Survival. The respective indemnities, representations, warranties and agreements of the Company and the Underwriter contained in this Agreement or made by or on its behalf, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Stock and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any person controlling any of them. 15.

(the "Company") and that the Underwriter proposes to reoffer the Shares to the public (the "Offering"). In consideration of the execution of the Underwriting Agreement by the Underwriter, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without your prior written consent, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any shares of Common Stock (including, without limitation, shares of Common Stock that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and shares of Common Stock that may be issued upon exercise of any option or warrant) or securities convertible into or exchangeable for Common Stock (other than the Shares) owned by the undersigned on the date of execution of this Lock-Up Letter Agreement or on the date of the completion of the Offering, or (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such shares of Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise, for a period of 60 days after the date of the final Prospectus relating to the Offering; provided, however, that the foregoing restrictions shall not apply to any bona fide gift of Common Stock to a donee that agrees in writing for the benefit of the Underwriter to be bound by the foregoing restrictions with respect to such shares of Common Stock. In furtherance of the foregoing, the Company and its Transfer Agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement. It is understood that, if the Company notifies you that it does not intend to proceed with the Offering, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares, the undersigned will be released from its obligations under this Lock-Up Letter Agreement. The undersigned understands that the Company and the Underwriter will proceed with the Offering in reliance on this Lock-Up Letter Agreement. Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriter. The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned. Very truly yours, Dated: _______________ A-2
