“The Securities covered hereby have not been registered under the U.S. Securities Act of 1933 (the “Securities Act”) and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of their distribution at any time or (ii) otherwise until 40 days after the later of the date of the commencement of the offering and the closing date, except in either case in accordance with Regulation S (or Rule 144A if available) under the Securities Act. Terms used above have the meanings given to them by Regulation S.”

Terms used in this subsection (b) have the meanings given to them by Regulation S.

(c) Each Purchaser severally agrees that it and each of its affiliates have not entered and will not enter into any contractual arrangement with respect to the distribution of the Offered Securities except for any such arrangements with the other Purchasers or affiliates of the other Purchasers with the prior written consent of the Company.

(d) Each Purchaser severally agrees that it and each of its affiliates will not offer or sell the Offered Securities in the United States by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) under the Securities Act, including, but not limited to (i) any advertisement, article, notice or other communication published in any newspaper, magazine or similar media or broadcast over television or radio; or (ii) any seminar or meeting whose attendees have been invited by any general solicitation or general advertising. Each Purchaser severally agrees, with respect to resales made in reliance on Rule 144A of any of the Offered Securities, to deliver either with the confirmation of such resale or otherwise prior to settlement of such resale a notice to the effect that the resale of such Offered Securities has been made in reliance upon the exemption from the registration requirements of the Securities Act provided by Rule 144A.

(e) Each of the Purchasers severally represents and agrees that (i) it has not offered or sold and prior to the expiry of a period of six months from the Closing Date, will not offer or sell any Offered Securities to persons in the United Kingdom except to persons whose ordinary activities involve them in acquiring, holding, managing or disposing of investments (as principal or agent) for the purposes of their businesses or otherwise in circumstances which have not resulted and will not result in an offer to the public in the United Kingdom within the meaning of the Public Offers of Securities Regulations 1995; (ii) it has only communicated or caused to be communicated and will only communicate or cause to be communicated any invitation or inducement to engage in investment activity (within the meaning of Section 21 of the Financial Services and Markets Act 2000 (the “FSMA”)) received by it in connection with the issue or sale of any Offered Securities in circumstances in which Section 21(1) of the FSMA does not apply to the Company or any of the Guarantors; and (iii) it has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to the Offered Securities in, from or otherwise involving the United Kingdom.

5. Certain Agreements of the Company and the Guarantors. The Company and the Guarantors, jointly and severally, agree with the several Purchasers that:

(a) The Company will advise CSFB promptly of any proposal to amend or supplement the Offering Document and will not effect such amendment or supplementation without CSFB’s consent. If, at any time prior to the completion of the resale of the Offered Securities by the Purchasers, any event occurs as a result of which the Offering Document as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any such time to amend or supplement the Offering Document to comply with any applicable law, the Company promptly will notify CSFB of such event and promptly will prepare, at its own expense, an amendment or supplement which will correct such statement or omission or effect such compliance. Neither CSFB’s consent to, nor the Purchasers’ delivery to offerees or investors of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 6.

(b) The Company will furnish to CSFB copies of any preliminary offering circular, the Offering Document and all amendments and supplements to such documents, in each case as soon as available and in such quantities as CSFB requests. At any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company will promptly furnish or cause to be furnished to CSFB and, upon request, to each of the other Purchasers, and, upon request of holders and prospective purchasers of the Offered Securities, to such holders and purchasers, copies of the information required to be delivered to holders and prospective purchasers of the Offered Securities pursuant to Rule 144A(d)(4) under the Securities Act (or any successor provision thereto) in order to permit compliance with Rule 144A in connection with resales by such holders of the Offered Securities. The Company will pay the expenses of printing and distributing to the Purchasers all such documents.

(c) The Company will arrange for the qualification of the Offered Securities for sale and the determination of their eligibility for investmentunder the laws of such jurisdictions in the United States and Canada as CSFB designates and will continue such qualifications in effect so long as required for the resale of the Offered Securities by the Purchasers, provided that the Company will not be required to qualify as a foreign corporation or to file a general consent to service of process in any such state.

(d) During the period of two years after the Closing Date, the Company will, upon request, furnish to CSFB, each of the other Purchasers and any holder of the Offered Securities a copy of the restrictions on transfer applicable to the Offered Securities.

(e) During the period of two years after the Closing Date, the Company will not, and will not permit any of its affiliates (as defined in Rule 144 under the Securities Act) to, resell any of the Offered Securities that have been reacquired by any of them.

(f) During the period of two years after the Closing Date, the Company will not be or become, an open-end investment company, unit investment trust or face-amount certificate company that is or is required to be registered under Section 8 of the Investment Company Act.

(g) The Company and the Guarantors, jointly and severally, will pay all expenses incidental to the performance of its obligations under this Agreement, the First Supplemental Indenture and the Registration Rights Agreement, including (i) the fees and expenses of the Trustee and its professional advisers; (ii) all expenses in connection with the execution, issue, authentication, packaging and initial delivery of the Offered Securities and, as applicable, the Exchange Securities, the preparation and printing of this Agreement, the Registration Rights Agreement, the Offered Securities, the First Supplemental Indenture, the Offering Document and amendments and supplements thereto, and any other document relating to the issuance, offer, sale and delivery of the Offered Securities and, as applicable, the Exchange Securities; (iii) the cost of listing the Offered Securities and qualifying the Offered Securities for trading in The Portal^SM Market and any expenses incidental thereto; (iv) the cost of any advertising approved by the Company in connection with the issue of the Offered Securities; (v) any expenses (including fees and disbursements of counsel) incurred in connection with qualification of the Offered Securities or the Exchange Securities for sale under the laws of such jurisdictions in the United States and Canada as CSFB designates and the printing of memoranda relating

thereto; (vi) any fees charged by investment rating agencies for the rating of the Offered Securities or the Exchange Securities; and (vii) expenses incurred in distributing preliminary offering circulars and the Offering Document (including any amendments and supplements thereto) to the Purchasers. The Company and the Guarantors on the one hand and the Purchasers on the other will each pay half of the travel expenses and any other expenses of the Purchasers and the Company incurred in connection with attending or hosting meetings with prospective purchasers of the Offered Securities.

(h) In connection with the offering, until CSFB has notified the Company and the other Purchasers of the completion of the resale of the Offered Securities, neither the Company nor any of its affiliates has or will, either alone or with one or more other persons, bid for or purchase for any account in which it or any of its affiliates has a beneficial interest any Offered Securities or attempt to induce any person to purchase any Offered Securities; and neither it nor any of its affiliates will make bids or purchases for the purpose of creating actual, or apparent, active trading in, or of raising the price of, the Offered Securities.

(i) For a period of 90 days after the date of the initial offering of the Offered Securities by the Purchasers, none of the Company nor any of the Guarantors will offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement under the Act (other than the Exchange Offer Registration Statement or the Shelf Registration Statement (each as defined in the Registration Rights Agreement)) relating to, any United States dollar-denominated debt securities issued or guaranteed by the Company or any Guarantor and having a maturity of more than one year from the date of issue; provided that this provision shall not prohibit the issuance of the Exchange Securities. Neither the Company nor any Guarantor will at any time offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any securities under circumstances where such offer, sale, pledge, contract or disposition would cause the exemption afforded by Section 4(2) of the Securities Act or the safe harbor of Regulation S thereunder to cease to be applicable to the offer and sale of the Offered Securities.

(j) The Company will use its reasonable best efforts to cause the Offered Securities to be eligible for The Portal^SM Market.

(k) The Fourth Amendment to the Second Amended and Restated Credit Agreement shall be in full force and effect.

6. Conditions of the Obligations of the Purchasers. The obligations of the several Purchasers to purchase and pay for the Offered Securities on the Closing Date will be subject to the accuracy of the representations and warranties on the part of the Company and each of the Guarantors herein on the date hereof and the Closing Date, to the accuracy of the statements of officers of the Company and each of the Guarantors made pursuant to the provisions hereof, to the performance by the Company and each of the Guarantors of their respective obligations hereunder and to the following additional conditions precedent:

(a) The Purchasers shall have received a letter, dated the date of this Agreement, of Ernst & Young LLP confirming that they are independent public accountants within the meaning of the Securities Act and the applicable published rules and regulations thereunder (“Rules and Regulations”) and to the effect that:

(i) in their opinion, the financial statements examined by them and included in the Offering Document and in the Exchange Act Reports comply as to form in all material respects with the applicable accounting requirements of the Securities Act and the related published Rules and Regulations;

(ii) on the basis of a reading of the latest available interim financial statements of the Company, inquiries of officials of the Company who have responsibility for financial and accounting matters and other specified procedures, nothing came to their attention that caused them to believe that:

(A) at the date of the latest available balance sheet read by such accountants, or at a subsequent specified date not more than three business days prior to the date of this Agreement, there was any change in the capital stock or any increase in short-term indebtedness or long-term debt of the Company and its consolidated subsidiaries or, at the date of the latest available balance sheet read by such accountants, there was any decrease in consolidated net current assets or net assets, as compared

with amounts shown on the latest balance sheet included or incorporated by reference in the Offering Document; or

(B) for the period from the closing date of the latest income statement included or incorporated by reference in the Offering Document to the closing date of the latest available income statement read by such accountants there were any decreases, as compared with the corresponding period of the previous year and with the period of corresponding length ended the date of the latest income statement included in the Offering Document, in consolidated net sales, net operating income, consolidated net income or in the ratio of earnings to fixed charges;

except in all cases set forth in clauses A and Babove for changes, increases or decreases which the Offering Document disclose have occurred or may occur or which are described in such letter; and

(iii) they have compared specified dollar amounts (or percentages derived from such dollar amounts) and other financial information contained in the Offering Document and the Exchange Act Reports (in each case to the extent that such dollar amounts, percentages and other financial information are derived from the general accounting records of the Company and the Subsidiaries subject to the internal controls of the Company’s accounting system or are derived directly from such records by analysis or computation) with the results obtained from inquiries, a reading of such general accounting records and other procedures specified in such letter and have found such dollar amounts, percentages and other financial information to be in agreement with such results, except as otherwise specified in such letter.

(b) Subsequent to the execution and delivery of this Agreement, there shall not have occurred (i) any change, or any development or event involving a prospective change, in the condition (financial or other), business, properties or results of operations of the Company and the Subsidiaries taken as one enterprise which, in the judgment of a majority in interest of the Purchasers, including CSFB, is material and adverse and makes it impractical or inadvisable to proceed with completion of the offering or the sale of and payment for the Offered Securities; (ii) any downgrading in the rating of any debt securities of the Company by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Securities Act), or any public announcement that any such organization has under surveillance or review its rating of any debt securities of the Company (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating) or any announcement that the Company has been placed on negative outlook; (iii) any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the judgment of a majority in interest of the Purchasers, including CSFB, be likely to prejudice materially the success of the proposed issue, sale or distribution of the Offered Securities, whether in the primary market or in respect of dealings in the secondary market; (iv) any material suspension or material limitation of trading in securities generally on the New York Stock Exchange or any setting of minimum prices for trading on such exchange, or any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (v) any banking moratorium declared by U.S. Federal or New York authorities; (vi) any major disruption of settlements of securities or clearance services in the United States; or (vii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of a majority in interest of the Purchasers, including CSFB, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency makes it impractical or inadvisable to proceed with completion of the offering or sale of and payment for the Offered Securities.

7. Indemnification and Contribution.

(a) The Company and each of the Guarantors, jointly and severally, will indemnify and hold harmless each Purchaser, its partners, directors and officers and each person, if any, who controls such Purchaser within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such Purchaser may become subject, under the Securities Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Offering Document, or any amendment or supplement thereto, or any related preliminary offering circular or the Exchange Act Reports, or arise out of or are based upon the omission or alleged omission to state therein 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, not misleading, including any losses, claims, damages or liabilities arising out of or based upon the Company’s or such Guarantor’s failure to perform its obligations under Section 5(a) of this Agreement, and will reimburse each Purchaser for any legal or other expenses reasonably incurred by such Purchaser in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company and each Guarantor will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Purchaser through CSFB specifically for use therein, it being understood and agreed that the only such information consists of the information described as such in subsection (b) below; provided, further, however, that the foregoing indemnity agreement with respect to losses, claims, damages or liabilities shall not inure to the benefit of any Purchaser (or any person controlling any Purchaser) with respect to any losses, claims, damages arising out of or based upon (i) any untrue statement or alleged untrue statement of any material fact in the preliminary offering circular or (ii) the omission or alleged omission to state in the preliminary offering circular a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, if: (A) the Company furnished sufficient copies of the Offering Circular on a timely basis to permit delivery of the Offering Circular to all persons purchasing notes from the Purchasers in the initial resale of such notes (such persons “Initial Resale Purchasers”) at or prior to the written confirmation of the sale of the Offered Securities to such person; (B) the Initial Resale Purchaser asserting such losses, claims, damages or liabilities purchased Offered Securities in the initial resale from the Purchasers and a copy of the Offering Circular (but excluding the documents incorporated therein by reference) was not sent or given by or on behalf of such Purchaser to such Initial Resale Purchaser; and (C) the Offering Circular would have cured the defect giving rise to such losses, claims, damages or liabilities.

(b) Each Purchaser will severally and not jointly indemnify and hold harmless the Company and each Guarantor, their directors and officers and each person, if any, who controls the Company or such Guarantor within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which the Company or such Guarantor may become subject, under the Securities Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Offering Document, or any amendment or supplement thereto, or any related preliminary offering circular, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Purchaser through CSFB specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Purchaser consists of the sixth paragraph and the tenth paragraph under the caption “Plan of Distribution”; provided, however, that the Purchasers shall not be liable for any losses, claims, damages or liabilities arising out of or based upon the Company’s or such Guarantor’s failure to perform its obligations under Section 5(a) of this Agreement.

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof, but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section 7 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes (i) an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors on the one hand and the Purchasers on the other from the offering of the Offered Securities 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 and the Guarantors on the one hand and the Purchasers on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Guarantors bear to the total discounts and commissions received by the Purchasers from the Company and the Guarantors under this Agreement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact

relates to information supplied by the Company and the Guarantors or the Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Purchaser shall be required to contribute any amount in excess of the amount by which the total discounts, fees and commissions received by such Purchaser exceeds the amount of any damages which such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Purchasers’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint.

(e) The obligations of the Company and the Guarantors under this Section 7 shall be in addition to any liability which the Company and the Guarantors may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Purchaser within the meaning of the Securities Act or the Exchange Act; and the obligations of the Purchasers under this Section 7 shall be in addition to any liability which the several Purchasers may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Company or any Guarantor within the meaning of the Securities Act or the Exchange Act.

8. Default of Purchasers. If any Purchaser or Purchasers default in their obligations to purchase the Offered Securities hereunder on the Closing Date and the aggregate principal amount of the Offered Securities that such defaulting Purchaser or Purchasers agreed but failed to purchase does not exceed 10% of the total principal amount of the Offered Securities, CSFB may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Purchasers, but if no such arrangements are made by the Closing Date, the non-defaulting Purchasers shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Purchasers agreed but failed to purchase. If any Purchaser or Purchasers so default and the aggregate principal amount of the Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of the Offered Securities and arrangements satisfactory to CSFB and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Purchaser or the Company or any of the Guarantors, except as provided in Section 9. As used in this Agreement, the term “Purchaser” includes any person substituted for a Purchaser under this Section 8. Nothing herein will relieve a defaulting Purchaser from liability for its default.

9. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company and the Guarantors or their respective officers and of the several Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Purchaser, the Company, the Guarantors or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to Section 8 or if for any reason the purchase of the Offered Securities by the Purchasers is not consummated, the Company and each of the Guarantors shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Company and the Purchasers pursuant to Section 7 shall remain in effect. If the purchase of the Offered Securities by the Purchasers is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 8 or the occurrence of any event specified in clause (iii), (iv), (v), (vi) or (vii) of Section 6(b), the Company will reimburse the Purchasers for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities.

10. Notices. All communications hereunder will be in writing and, if sent to the Purchasers will be mailed, delivered or faxed and confirmed to the Purchasers c/o Credit Suisse First Boston LLC, Eleven Madison Avenue, New York, N.Y. 10010-3629, Attention: Transactions Advisory Group (Fax: 212 ###-###-####), or, if sent to the Company, will be mailed, delivered or faxed and confirmed to it at 5555 San Felipe, Suite 1200, Houston, TX 77056, Attention: Secretary (Fax: 713 ###-###-####); provided, however, that any notice to a Purchaser pursuant to Section 7 will be mailed, delivered or faxed and confirmed to such Purchaser.

11. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the controlling persons referred to in Section 7, and no other person will have any right or obligation hereunder, except that holders of the Offered Securities shall be entitled to enforce the agreements for their benefit contained in the second and third sentences of Section 5(b) hereof against the Company as if such holders were parties hereto.

12. Representation of Purchasers. You will act for the several Purchasers in connection with this purchase, and any action under this Agreement taken by you jointly or by CSFB will be binding upon all the Purchasers.

13. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

14. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York without regard to principles of conflicts of laws.

The Company and each Guarantor hereby submit to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

If the foregoing is in accordance with the Purchasers’ understanding of our agreement, kindly sign and return to the Company one of the counterparts hereof, whereupon it will become a binding agreement among the Company, the Guarantors and the several Purchasers in accordance with its terms.
