The Company hereby agrees with Credit Suisse First Boston Corporation (the

         2. Representations and Warranties of the Company. The Company
represents and warrants to, and agrees with, the Underwriter that:

                  (a) A registration statement (No. 333-63429), including a
         prospectus, relating to the Offered Securities has been filed with the
         Securities and Exchange Commission ("COMMISSION") and has been declared
         effective by the Commission. Such registration statement, as amended
         through the date of this Agreement, including all documents
         incorporated or deemed to be incorporated by reference therein, as from
         time to time amended or supplemented pursuant to the Securities
         Exchange Act of 1934 ("EXCHANGE ACT"), and the rules and regulations of
         the Commission thereunder, or otherwise, are hereinafter referred to as
         the "REGISTRATION STATEMENT", and the prospectus included in such
         Registration Statement, as supplemented to reflect the terms of the
         Offered Securities and the terms of offering thereof, as first filed
         with the Commission on June 5, 2002 pursuant to and in accordance with

         hereinafter referred to as the "PROSPECTUS." No document has been or
         will be prepared or distributed in reliance on Rule 434 under the Act.

                  (b) On the effective date of the Registration Statement, such

         requirements of the Act, the Trust Indenture Act of 1939 ("TRUST
         INDENTURE Act") and the rules and regulations of the Commission ("RULES
         AND REGULATIONS") and did not include any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary to make the statements therein not misleading; the
         Registration Statement, as of the date of this


         Agreement, conforms and, as amended or supplemented, if applicable,
         will conform in all material respects to the requirements of the Act,
         the Trust Indenture Act and the Rules and Regulations, and does not
         include and, as amended or supplemented, if applicable, will not
         include any untrue statement of a material fact or omit to state any
         material fact required to be stated therein or necessary to make the
         statements therein not misleading; the Prospectus, as of the date of
         its filing, conforms, and as amended or supplemented, if applicable,
         will conform in all material respects to the requirements of the Act,
         the Trust Indenture Act, and the Rules and Regulations and does not
         include, and as amended or supplemented, if applicable, will not
         include any untrue statement of a material fact or omit to state any
         material fact required to be stated therein or necessary to make the
         statements therein, in light of the circumstances under which they were
         made, not misleading; except that the provisions in the foregoing
         paragraph do not apply to statements in or omissions from any of such
         documents based upon written information furnished to the Company by
         any Underwriter through the Representative, if any, specifically for
         use therein.

                  (c) The documents incorporated or deemed to be incorporated by
         reference in the Registration Statement and the Prospectus, when they
         became effective or at the time they were or hereafter are filed with
         the Commission, complied and will comply in all material respects with
         the requirements of the Act, the Exchange Act or the Rules and
         Regulations, as applicable, and, when read together with the other
         information in the Prospectus, at the time the Registration Statement
         became effective, at the time the Prospectus was issued and on the
         Closing Date (as defined below), did not and will not contain an untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary to make the statements therein, and
         with respect to the Prospectus, in light of the circumstances under
         which they were made, not misleading.

                  (d) The Company has been duly incorporated and is an existing
         corporation in good standing under the laws of the State of Delaware,
         with full corporate power and authority to own its properties and
         conduct its business as described in the Prospectus; and the Company is
         duly qualified to do business as a foreign corporation in good standing
         in all other jurisdictions in which its ownership or lease of property
         or the conduct of its business requires such qualification, except
         where the failure to be so qualified, individually or in the aggregate,
         would not have a material adverse effect on the financial condition,
         business, properties or results of operations of the Company and its
         subsidiaries taken as a whole ("MATERIAL ADVERSE EFFECT").

                  (e) Each significant subsidiary (as defined in Regulation S-X
         of the Act and set forth on Schedule A hereto) ("SIGNIFICANT
         SUBSIDIARY") of the Company has been duly incorporated or formed, as
         the case may be, and is an existing corporation, limited liability
         company or limited partnership in good standing under the laws of the
         jurisdiction of its incorporation or formation, as the case may be,
         with power and authority (corporate or other) to own its properties and
         conduct its business as described in the Prospectus; and each such
         Significant Subsidiary is duly qualified to do business as a foreign
         corporation, limited liability company or limited partnership in good
         standing in all other jurisdictions in which its ownership or lease of
         property or the conduct of its business requires such qualification,
         except where the failure to be so qualified, individually or in the
         aggregate, would not have a Material Adverse Effect; all of the issued
         and outstanding equity interests of each Significant Subsidiary have
         been duly authorized and validly issued and are fully paid and
         nonassessable; and the equity interests of each Significant Subsidiary
         owned by the Company, directly or through subsidiaries, are owned free
         from liens, claims, or adverse interests of any nature.

                  (f) The Original Indenture has been duly authorized, executed
         and delivered and has been qualified under the Trust Indenture Act with
         respect to the Offered Securities registered thereby; the Offered
         Securities have been duly authorized; and when the Offered Securities
         are delivered and paid for pursuant to this Agreement on June 10, 2002
         ("CLOSING DATE"), the Supplemental Indenture will have been duly
         authorized, executed and delivered and will have been qualified under
         the Trust Indenture Act with respect to the Offered Securities
         registered thereby on the Closing Date, such Offered Securities will
         have been duly executed, authenticated, issued and delivered and will
         conform in all material respects to the description thereof contained
         in the Prospectus and the Indenture, and such Offered Securities will
         constitute valid and legally binding obligations of the Company,
         enforceable in accordance with their


                                       2


         terms, subject to bankruptcy, insolvency, fraudulent transfer,
         reorganization, moratorium and similar laws of general applicability
         relating to or affecting creditors' rights and to general equity
         principles.

                  (g) No consent, approval, authorization, or order of, or
         filing with, any governmental agency or body or any court is required
         for the consummation of the transactions contemplated by this Agreement
         in connection with the issuance and sale of the Offered Securities by
         the Company, except such as have been obtained and made under the Act
         and the Trust Indenture Act and such as may be required under state
         securities laws.

                  (h) The execution, delivery and performance of the Indenture
         and this Agreement, and the issuance and sale of the Offered Securities
         and compliance with the terms and provisions thereof will not result in
         a breach or violation of any of the terms and provisions of, or
         constitute a default under, any statute, any rule, regulation or order
         of any governmental agency or body or any court, domestic or foreign,
         having jurisdiction over the Company or any Significant Subsidiary or
         any of their properties, or any agreement or instrument to which the
         Company or any such Significant Subsidiary is a party or by which the
         Company or any such Significant Subsidiary is bound or to which any of
         the properties of the Company or any Significant Subsidiary is subject,
         or the charter or by-laws of the Company or any such Significant
         Subsidiary, and the Company has full power and authority to authorize,
         issue and sell the Offered Securities as contemplated by this
         Agreement.

                  (i) This Agreement has been duly authorized, executed and
         delivered by the Company.

                  (j) Neither the Company nor any Significant Subsidiary is (i)
         in violation of its respective charter or by-laws or (ii) in default in
         the performance of any obligation, agreement, covenant or condition
         contained in any indenture, loan agreement, mortgage, lease or other
         agreement or instrument that is material to the Company and its
         subsidiaries, taken as a whole, to which the Company or any Significant
         Subsidiary is a party or by which the Company or any Significant
         Subsidiary or their respective property is bound.

                  (k) Except as disclosed in the Prospectus, the Company and its
         subsidiaries have good and indefeasible title to all real properties
         and all other properties and assets owned by them, in each case free
         from liens, encumbrances and defects that would materially affect the
         value thereof or materially interfere with the use made or to be made
         thereof by them; and except as disclosed in the Prospectus, the Company
         and its Significant Subsidiaries hold any leased real or personal
         property under valid and enforceable leases with no exceptions that
         would materially interfere with the use made or to be made thereof by
         them.

                  (l) Except as disclosed in the Prospectus, neither the Company
         nor any of its Significant Subsidiaries is in violation of any statute,
         any rule, regulation, decision or order of any governmental agency or
         body or any court, domestic or foreign, relating to the use, disposal
         or release of hazardous or toxic substances or relating to the
         protection or restoration of the environment or human exposure to
         hazardous or toxic substances (collectively, "ENVIRONMENTAL LAWS"),
         owns or operates any real property contaminated with any substance that
         is subject to any environmental laws, is liable for any off-site
         disposal or contamination pursuant to any environmental laws, or is
         subject to any claim relating to any environmental laws, which
         violation, contamination, liability or claim would, individually or in
         the aggregate, have a Material Adverse Effect; and, except as disclosed
         in the Prospectus, the Company is not aware of any pending
         investigation which might lead to such a claim.

                  (m) Except as disclosed in the Prospectus, there are no
         pending actions, suits or proceedings against or affecting the Company,
         any of its subsidiaries or any of their respective properties that, if
         determined adversely to the Company or any of its subsidiaries, would
         individually or in the aggregate have a Material Adverse Effect, or
         would materially and adversely affect the ability of the Company to
         perform its obligations under the Indenture or this Agreement, or which
         are otherwise material in the context of the sale of the Offered
         Securities; and no such actions, suits or proceedings are, to the
         Company's knowledge, threatened or contemplated.


                                       3


                  (n) The financial statements included in the Registration
         Statement and the Prospectus present fairly the consolidated financial
         position of the Company and its consolidated subsidiaries as of the
         dates shown and their results of operations and cash flows for the
         periods shown, and, except as otherwise disclosed in the Prospectus,
         such consolidated financial statements have been prepared in conformity
         with the generally accepted accounting principles in the United States
         applied on a consistent basis; and the schedules included in the
         Registration Statement present fairly the information required to be
         stated therein; and the assumptions used in preparing the pro forma
         financial statements incorporated by reference in the Registration
         Statement and the Prospectus provide a reasonable basis for presenting
         the significant effects directly attributable to the transactions or
         events described therein, the related pro forma adjustments give
         appropriate effect to those assumptions, and the pro forma columns
         therein reflect the proper application of those adjustments to the
         corresponding historical financial statement amounts.

                  (o) Except as disclosed in the Prospectus (exclusive of any
         amendments or supplements thereto subsequent to the date of this
         Agreement) since the date of the latest audited financial statements
         included in the Prospectus there has been no material adverse change,
         nor any development or event involving a prospective material adverse
         change, in the financial condition, business, properties or results of
         operations of the Company and its subsidiaries taken as a whole, and,
         except as disclosed in or contemplated by the Prospectus, there has
         been no dividend or distribution of any kind declared, paid or made by
         the Company on any class of its capital stock.

                  (p) No "nationally recognized statistical rating organization"
         as such term is defined for purposes of Rule 436(g)(2) under the Act
         has indicated to the Company that it is considering (i) the
         downgrading, suspension or withdrawal of, or any review for a possible
         change that does not indicate the direction of the possible change in,
         any rating assigned to the Company or any securities of the Company or
         (ii) any change in the outlook for any rating of the Company or any
         securities of the Company.

                  (q) The Company is not and, after giving effect to the
         offering and sale of the Offered Securities and the application of the
         proceeds thereof as described in the Prospectus, will not be (i) an
         "investment company" as defined in the Investment Company Act of 1940,
         as amended, or (ii) a "holding company" within the meaning of, or
         subject to regulation under, the Public Utility Holding Company Act of
         1935, as amended, and the rules and regulations promulgated by the
         Commission thereunder.

         3. Purchase, Sale and Delivery of Offered Securities. On the basis of
the representations, warranties and agreements herein contained, but subject to
the terms and conditions herein set forth, the Company agrees to sell to the
Underwriter, and the Underwriter agrees, to purchase from the Company, at a
purchase price of 99.014% of the principal amount thereof, the Offered
Securities.

                  The Company will deliver against payment of the purchase price
the Offered Securities in the form of one or more permanent global Securities in
definitive form (the "GLOBAL SECURITIES") deposited with the Trustee as
custodian for The Depository Trust Company ("DTC") and registered in the name of
Cede & Co., as nominee for DTC. Interests in any permanent global Securities
will be held only in book-entry form through DTC, except in the limited
circumstances described in the Prospectus. Payment for the Offered Securities
shall be made by the Underwriter in Federal (same day) funds by wire transfer to
an account at a bank acceptable to Credit Suisse First Boston Corporation
("CSFBC") and designated in writing by the Company, not less than 48 hours prior
to the Closing Date, at 9:00 A.M., (New York time), on June 10, 2002, or at such
other time not later than seven full business days thereafter as CSFBC and the
Company determine, such time being herein referred to as the "CLOSING DATE",
against delivery to the Trustee as custodian for DTC of the Global Securities
representing all of the Offered Securities. The Global Securities will be made
available for checking at the office of Andrews & Kurth Mayor, Day, Caldwell &
Keeton L.L.P. at least 24 hours prior to the Closing Date.


                                       4


         4. Offering by Underwriter. It is understood that the Underwriter
proposes to offer the Offered Securities for sale to the public as set forth in
the Prospectus.

         5. Certain Agreements of the Company. The Company agrees with the
Underwriter that it will furnish or otherwise make available to counsel for the
Underwriter, one conformed copy of the registration statement relating to the
Registered Securities, including all exhibits, in the form it became effective
and of all amendments thereto and that, in connection with each offering of
Offered Securities:

                  (a) The Company will file the Prospectus with the Commission
         pursuant to and in accordance with Rule 424(b)(2) (or, if applicable
         and if consented to by CSFBC, subparagraph (5)) not later than the
         second business day following the execution and delivery of this
         Agreement.

                  (b) During such period as, in the opinion of counsel for the
         Underwriter, a prospectus is required by law to be delivered in
         connection with sales by an Underwriter or a dealer, the Company will
         advise CSFBC promptly of any proposal to amend or supplement the
         Registration Statement or the Prospectus (except in the case of Annual
         Reports filed on Form 10-K or Quarterly Reports filed on Form 10-Q) and
         will afford CSFBC a reasonable opportunity to comment on any such
         proposed amendment or supplement (except in the case of reports to be
         filed by the Company in the ordinary course pursuant to the Exchange
         Act); and, during such period as, in the opinion of counsel for the
         Underwriter, a prospectus is required by law to be delivered in
         connection with sales by an Underwriter or a dealer, the Company will
         also advise CSFBC promptly of the filing of any such amendment or
         supplement (except in the case of reports to be filed by the Company in
         the ordinary course pursuant to the Exchange Act) and of the
         institution by the Commission of any stop order proceedings in respect
         of the Registration Statement or of any part thereof and will use its
         best efforts to prevent the issuance of any such stop order and to
         obtain as soon as possible its lifting, if issued.

                  (c) If, at any time when a prospectus relating to the Offered
         Securities is required to be delivered under the Act in connection with
         sales by any Underwriter or dealer, any event occurs as a result of
         which the Prospectus as then amended or supplemented would include an
         untrue statement of a material fact or omit to state any material fact
         necessary 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 time to amend the Prospectus to comply with the Act,
         the Company promptly will notify CSFBC of such event and will promptly
         prepare and file with the Commission, at its own expense, an amendment
         or supplement which will correct such statement or omission or an
         amendment which will effect such compliance. Neither CSFBC's consent
         to, nor the Underwriter's delivery of, any such amendment or supplement
         shall constitute a waiver of any of the conditions set forth in Section
         6 hereof.

                  (d) As soon as practicable, but not later than 16 months,
         after the date of this Agreement, the Company will make generally
         available to its security holders an earnings statement covering a
         period of at least 12 months beginning after the later of (i) the
         effective date of the most recent post-effective amendment to the
         Registration Statement to become effective prior to the date of this
         Agreement and (ii) the date of the Company's most recent Annual Report
         on Form 10-K filed with the Commission prior to the date of this
         Agreement, which will satisfy the provisions of Section 11(a) of the
         Act.

                  (e) The Company will furnish or make generally available to
         the Underwriter copies of the Registration Statement, including all
         exhibits, any related preliminary prospectus, and any related
         preliminary prospectus supplement, upon request of the Underwriter, and
         the Prospectus and all amendments and supplements to such documents, in
         each case as soon as available and in such quantities as CSFBC
         reasonably requests. The Company will pay the expenses of printing and
         distributing to the Underwriter all such documents.

                  (f) The Company will cooperate with the Underwriter in
         connection with the qualification of the Offered Securities for sale
         and the determination of their eligibility for investment under the
         laws of such jurisdictions as CSFBC designates and will continue such
         qualifications in effect so long as required for the distribution of
         the Offered Securities; provided, however, that the Company shall not
         be required in connection therewith to qualify as a foreign corporation
         in any jurisdiction in which it is not now so


                                       5


         qualified or to take any action that would subject it to general
         consent to service of process or taxation other than as to matters and
         transactions taken by the Company as contemplated herein that relates
         to the Prospectus, the Registration Statement, or the offering of the
         Offered Securities in any jurisdiction in which it is not now so
         qualified.

                  (g) During the period of two years hereafter, the Company will
         furnish or make generally available to the Underwriter as soon as
         practicable after the end of each fiscal year, a copy of its annual
         report to stockholders, if any, for such year; and the Company will
         furnish to the Underwriter as soon as available, a copy of each report
         and any definitive proxy statement of the Company filed with the
         Commission under the Exchange Act or mailed to stockholders.

                  (h) The Company will pay all expenses incident to the
         performance of its obligations under this Agreement, for any filing

         incurred in connection with qualification of the Offered Securities for

         purchasers of the Offered Securities and for expenses incurred in
         distributing preliminary prospectuses, if any, and the Prospectus

                  (i) The Company will not offer, sell, contract to sell, pledge
         or otherwise dispose of, directly or indirectly, or file with the
         Commission a registration statement under the Act relating to debt
         securities issued or guaranteed by the Company and having a maturity of

         6. Conditions of the Obligations of the Underwriter. The obligations of

Company of its obligations hereunder and to the following additional conditions
precedent:

                  (a) On or prior to the date of this Agreement, the Underwriter
         shall have received a letter, dated the date of delivery thereof, of
         PricewaterhouseCoopers LLP confirming that they are independent public
         accountants within the meaning of the Act and the applicable published
         Rules and Regulations thereunder and stating to the effect that:

                           (i) in their opinion the financial statements and any
                  schedules and any summary of earnings examined by them and
                  included in the Prospectus comply as to form in all material
                  respects with the applicable accounting requirements of the
                  Act and the related published Rules and Regulations;

                           (ii) they have performed the procedures specified by
                  the American Institute of Certified Public Accountants for a
                  review of interim financial information as described in
                  Statement of Auditing Standards No. 71, Interim Financial
                  Information, on any unaudited financial statements included in
                  the Registration Statement;

                           (iii) on the basis of the review referred to in
                  clause (ii) above, 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) the unaudited financial statements, if
                           any, and any summary of earnings included in the
                           Prospectus do not comply as to form in all material
                           respects with the


                                       6


                           applicable accounting requirements of the Act and the
                           related published Rules and Regulations or any
                           material modifications should be made to such
                           unaudited financial statements and summary of
                           earnings for them to be in conformity with generally
                           accepted accounting principles;

                                    (B) if any unaudited "capsule" information
                           is contained in the Prospectus, the unaudited
                           consolidated operating revenues, operating income,
                           net income and net income per share amounts or other
                           amounts constituting such "capsule" information and
                           described in such letter (i) do not agree with the
                           corresponding amounts set forth in the unaudited
                           consolidated financial statements; or (ii) were not
                           determined on a basis substantially consistent with
                           that of the corresponding amounts in the audited
                           statements of income;

                                    (C) 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 such letter, 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 in the Prospectus; or

                                    (D) for the period from the closing date of
                           the latest income statement included in the
                           Prospectus 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, in
                           consolidated operating revenues, operating income or
                           in net income;

                           except in all cases set forth in clauses (C) and (D)
                           above for changes, increases or decreases which the
                           Prospectus discloses have occurred or may occur or
                           which are described in such letter; and

                           (iv) they have compared specified dollar amounts (or
                  percentages derived from such dollar amounts) and other
                  financial information contained in the Prospectus (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 its 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.

                  All financial statements and schedules included in material
                  incorporated by reference into the Prospectus shall be deemed
                  included in the Prospectus for purposes of this subsection.

                  (b) The Prospectus shall have been filed with the Commission
         in accordance with the Rules and Regulations and Section 5(a) of this
         Agreement. No stop order suspending the effectiveness of the
         Registration Statement or of any part thereof shall have been issued
         and no proceedings for that purpose shall have been instituted or, to
         the knowledge of the Company or the Underwriter, shall be contemplated
         by the Commission.

                  (c) 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 financial
         condition, business, properties or results of operations of the Company
         and its subsidiaries taken as one enterprise which, in the judgment of
         the Underwriter, is material and adverse and makes it impractical or
         inadvisable to proceed with completion of the public 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 Act), or any public


                                       7


         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); (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 the Underwriter, 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 the Underwriter, the
         effect of any such attack, outbreak, escalation, act, declaration,
         calamity or emergency makes it impractical or inadvisable to proceed
         with completion of the public offering or the sale of and payment for
         the Offered Securities.

                  (d) The Underwriter shall have received an opinion, dated the
         Closing Date, of Locke Liddell & Sapp LLP, counsel for the Company, to
         the effect that:

                           (i) The Indenture has been duly authorized, executed

                  purchase price therefor in accordance with the terms of this
                  Agreement, will, constitute valid and legally binding
                  obligations of the Company enforceable in accordance with
                  their terms, except as (a) may be limited by bankruptcy,
                  insolvency, fraudulent conveyance or transfer, reorganization,
                  moratorium or similar laws relating to or affecting creditors'
                  rights generally and (b) rights of acceleration and the
                  availability of equitable remedies may be limited by equitable
                  principles of general applicability; and the Offered
                  Securities conform, as to legal matters, in all material
                  respects, to the description thereof contained in the
                  Prospectus;

                           (ii) No consent, approval, authorization or order of,

                  obtained and made under the Act and the Trust Indenture Act
                  and such as may be required under state securities laws, as to
                  which such counsel need not opine;

                           (iii) The execution and delivery by the Company of,
                  and the performance by the Company of its obligations under
                  the Indenture and this Agreement, and the issuance and sale by
                  the Company of the Offered Securities and compliance with the
                  terms and provisions thereof will not violate any provision of
                  applicable United States federal law, New York law or Delaware
                  General Corporation Law, or the charter or bylaws of the
                  Company or the charter or bylaws of any Significant
                  Subsidiary, and the Company has full power and authority to
                  authorize, issue and sell the Offered Securities as
                  contemplated by this Agreement;

                           (iv) The Registration Statement has become effective
                  under the Act, the Prospectus was filed with the Commission
                  pursuant to the subparagraph of Rule 424(b) specified in such
                  opinion on the date specified therein, and to the knowledge of
                  such counsel, no stop order suspending the effectiveness of
                  the Registration Statement or any part thereof has been issued
                  and no proceedings for that purpose have been instituted or
                  are pending or contemplated under the Act, and the
                  Registration Statement, as of its effective date, the
                  Prospectus, as of the date of this Agreement, and any
                  amendment or supplement thereto, as of its date, complied as
                  to form in all material respects with the requirements of the
                  Act, the Trust Indenture Act and the Rules and


                                       8


                  Regulations; in the course of the preparation by the Company
                  of the Prospectus (including documents incorporated by
                  reference therein), such counsel has participated in
                  conferences with certain of the officers and representatives
                  of the Company, the Company's independent accountants, the
                  Underwriter and counsel for the Underwriter at which the
                  Registration Statement and the Prospectus were discussed; no
                  facts have come to counsel's attention in the course of such
                  proceedings that have caused such counsel to believe that the
                  Registration Statement, as of its effective date, as of the
                  date of this Agreement or as of the Closing Date, or any
                  amendment thereto, as of its date or as of the Closing Date,
                  contained any untrue statement of a material fact or omitted
                  to state any material fact required to be stated therein or
                  necessary to make the statements therein not misleading or
                  that the Prospectus, as of the date of this Agreement or as of
                  such Closing Date, or any amendment or supplement thereto, as
                  of its date or as of the Closing Date, contained any untrue
                  statement of a material fact or omitted 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; the descriptions in the Registration Statement and
                  Prospectus of statutes, legal and governmental proceedings and
                  contracts and other documents are accurate in all material
                  respects and fairly present in all material respects the
                  information required to be shown; and such counsel does not
                  know of any legal or governmental proceedings required to be
                  described in the Prospectus which are not described as
                  required or of any contracts or documents of a character
                  required to be described in the Registration Statement or
                  Prospectus or to be filed as exhibits to the Registration
                  Statement which are not described and filed as required; it
                  being understood that such counsel need express no opinion as
                  to the financial statements and schedules or other financial
                  data contained or incorporated by reference in the
                  Registration Statement or the Prospectus;

                           (v) Each document, if any, filed pursuant to the
                  Exchange Act and incorporated by reference in the Prospectus
                  (except for financial statements and schedules and other
                  financial or statistical data included or incorporated by
                  reference therein or omitted therefrom as to which such
                  counsel need not express any opinion) appeared on its face to
                  be appropriately responsive in all material respects with the
                  Exchange Act; and the Registration Statement and Prospectus
                  (except for financial statements and schedules and other
                  financial data included or incorporated by reference therein
                  or omitted therefrom as to which such counsel need not express
                  any opinion) appeared on their face to be appropriately
                  responsive in all material respects with the requirements of
                  the Act;

                           (vi) This Agreement has been duly authorized,
                  executed and delivered by the Company; and

                           (vii) The Company is not and, after giving effect to
                  the offering and sale of the Securities and the application of
                  the proceeds thereof as described in the Prospectus, will not
                  be, (i) an "investment company" as such term is defined in the
                  Investment Company Act of 1940, as amended, or (ii) a "holding
                  company" within the meaning of, or subject to regulation
                  under, the Public Utility Holding Company Act of 1935, as
                  amended, and the rules and regulations promulgated by the
                  Commission thereunder.

                  (e) The Underwriter shall have received from David Siddell as
         Special Counsel for the Company, an opinion, dated the Closing Date, to
         the effect that:

                           (i) Each of the Company and its Significant
                  Subsidiaries has been duly incorporated, is validly existing
                  as a corporation in good standing under the laws of its
                  jurisdiction of incorporation and has the corporate power and
                  authority to own, lease and operate its properties and to
                  conduct its business as described in the Prospectus, and each
                  is duly qualified as a foreign corporation to transact
                  business and is in good standing in each jurisdiction in which
                  the conduct of its business or its ownership or leasing of
                  property requires such qualification, except where the failure
                  to be so qualified or to be in good standing, individually or
                  in the aggregate, would not have a material adverse effect on
                  the business, prospects, financial condition or results of
                  operations of the Company and its subsidiaries, taken as a
                  whole.

                           (ii) The execution, delivery and performance of this
                  Agreement, the Indenture and the Securities by the Company,
                  the compliance by the Company with all the provisions hereof
                  and thereof and the consummation of the transactions
                  contemplated hereby and thereby will not, to such counsel's
                  knowledge, (A) violate any indenture, loan agreement,
                  mortgage, lease or other agreement or instrument to which the
                  Company or any Significant Subsidiary is a party or by which
                  the Company or any subsidiary or their respective property is
                  bound or (B) violate or conflict with any judgment, order or
                  decree of any court or any governmental body or agency having
                  jurisdiction over the Company, any subsidiary or their
                  respective property, except in each case, for such violations
                  as would not have a material adverse effect on the business,
                  prospects, financial condition or results of operation of the
                  Company and its subsidiaries, taken as a whole.

                           (iii) To such counsel's knowledge after due inquiry,
                  there are no legal or governmental proceedings required to be
                  described in the Prospectus which are not described as
                  required or of any contracts or documents of a character
                  required to be described in the Registration Statement or
                  Prospectus or to be filed as exhibits to the Registration
                  Statement which are not described and filed as required; it
                  being understood that such counsel need express no opinion as
                  to the financial statements or schedules or other financial
                  data contained in the Registration Statement or the
                  Prospectus.

                           (iv) The statements under (A) the caption "Item 3 -
                  Legal Proceedings" of the Company's most recent annual report
                  on Form 10-K incorporated by reference into the Prospectus,
                  (B) the caption "Item 1 - Legal Proceedings" of Part II of the
                  Company's quarterly reports on Form 10-Q filed since such
                  annual report, in each case insofar as such statements
                  constitute summaries of the legal matters, documents or
                  proceedings referred to therein, fairly present as of the date
                  of the applicable report the information disclosed therein in
                  all material respects.

                           (v) (A) The execution and delivery by the Company of,
                  and the performance by the Company of its obligations under,
                  this Agreement will not violate any provisions of any
                  applicable laws and regulations specifically governing the
                  generation, transportation, distribution or delivery of
                  natural gas, oil, electricity or other related commodities or
                  services, including pipelines, transmission lines, storage
                  facilities and related facilities and equipment, or the import
                  or export of such commodities or services (collectively, the
                  "ENERGY INDUSTRY") and (B) no consent, approval, authorization
                  or order of or qualification with any United States federal
                  body or agency specifically regulating the Energy Industry is
                  required for the performance by the Company of its obligations
                  under this Agreement, except in each of the foregoing cases
                  for such violations or failures to obtain such consent,
                  approval, authorization, order or qualification as would not
                  have a material adverse effect on the business, prospects,
                  financial condition or results of operation of the Company and
                  its subsidiaries, taken as a whole.

                  (f) The Underwriter shall have received from Andrews & Kurth
         Mayor, Day, Caldwell & Keeton L.L.P., counsel for the Underwriter, such
         opinion or opinions, dated such Closing Date, with respect to the
         incorporation of the Company, the validity of the Offered Securities
         delivered on such Closing Date, the Registration Statement, the
         Prospectus and other related matters as the Underwriter may require,
         and the Company shall have furnished to such counsel such documents as
         they request for the purpose of enabling them to pass upon such
         matters.

                  (g) The Underwriter shall have received a certificate, dated
         the Closing Date, of the President or any Vice President and a
         principal financial or accounting officer of the Company in which such
         officers, to the best of their knowledge after reasonable
         investigation, shall state that the representations and warranties of
         the Company in this Agreement are true and correct, that the Company
         has complied with all agreements and satisfied all conditions on its
         part to be performed or satisfied hereunder at or prior to the Closing
         Date, that no stop order suspending the effectiveness of the
         Registration Statement or of any part thereof has been issued and no
         proceedings for that purpose have been instituted or are contemplated
         by the Commission and that, subsequent to the date of the most recent
         financial statements in the Prospectus, there has been no material
         adverse change, nor any development or event involving a prospective
         material


                                       10


         adverse change, in the financial condition, business, properties or
         results of operations of the Company and its subsidiaries, taken as a
         whole, except as set forth in or contemplated by the Prospectus or as
         described in such certificate.

                  (h) The Underwriter shall have received a letter, dated such
         Closing Date, of PricewaterhouseCoopers LLP which meets the
         requirements of subsection (a) of this Section, except that the
         specified date referred to in such subsection will be a date not more
         than three days prior to such Closing Date for the purposes of this
         subsection.

The Company will furnish the Underwriter with such conformed copies of such
opinions, certificates, letters and documents as the Underwriter reasonably
requests. CSFBC may in its sole discretion waive compliance with any conditions
to the obligations of the Underwriter hereunder.

         7. Indemnification and Contribution. (a) The Company will indemnify and
hold harmless the Underwriter, its partners, directors and officers and each
person, if any, who controls the Underwriter within the meaning of Section 15 of
the Act, against any losses, claims, damages or liabilities, joint or several,
to which the Underwriter may become subject, under the 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 any Registration Statement, the Prospectus, or
any amendment or supplement thereto, or any preliminary prospectus or
preliminary prospectus supplement related to the Offered Securities, 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 to make the statements
therein not misleading, and will reimburse the Underwriter for any legal or
other expenses reasonably incurred by the Underwriter in connection with
investigating or defending any such loss, claim, damage, liability or action as
such expenses are incurred; provided, however, that the Company 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 the Underwriter specifically for use therein, it being understood and
agreed that the only such information furnished by the Underwriter consists of
the information described as such in subsection (b) below; and provided,
further, that with respect to any untrue statement or alleged untrue statement
in or omission or alleged omission from any preliminary prospectus or
preliminary prospectus supplement related to the Offered Securities, the
indemnity agreement contained in this subsection (a) shall not inure to the
benefit of the Underwriter from whom the person asserting such losses, claims,
damages or liabilities purchased the Offered Securities concerned, to the extent
that a prospectus relating to such Offered Securities was required to be
delivered by the Underwriter under the Act in connection with such purchase and
any such loss, claim, damage or liability of the Underwriter results from the
fact that there was not sent or given to such person, at or prior to the written
confirmation of the sale of such Offered Securities to such person, a copy of
the Prospectus (exclusive of material incorporated by reference) if the Company
had previously furnished copies thereof to the Underwriter.

                  (b) The Underwriter will indemnify and hold harmless the
         Company, its directors and officers and each person, if any who
         controls the Company within the meaning of Section 15 of the Act,
         against any losses, claims, damages or liabilities to which the Company
         may become subject, under the 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 any Registration Statement,
         the Prospectus, or any amendment or supplement thereto, or any related
         preliminary prospectus or preliminary prospectus supplement, 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 to
         make the statements therein 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 the
         Underwriter 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 the Underwriter consists of
         the following information in the Prospectus furnished on behalf of the
         Underwriter: the third paragraph under the caption "Underwriting," the
         second and third sentences in the fifth paragraph under the caption
         "Underwriting" and the information contained in the paragraphs related
         to stabilizing


                                       11


         transactions, over-allotment transactions, syndicate covering
         transactions and penalty bids under the caption "Underwriting".

                  (c) Promptly after receipt by an indemnified party under this
         Section 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 omission so to
         notify the indemnifying party will not relieve it from any liability
         which it may have to any 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 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 (i) includes 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 a failure to act by or on
         behalf of an indemnified party.

                  (d) If the indemnification provided for in this Section 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 on the one hand
         and the Underwriter on the other from the offering of the 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 on the one hand and the Underwriter 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 on the one hand and the Underwriter 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 bear to
         the total underwriting discounts and commissions received by the
         Underwriter. 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 or the Underwriter
         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), the Underwriter shall not be required to contribute any
         amount in excess of the amount by which the total price at which the
         Securities underwritten by it and distributed to the public were
         offered to the public exceeds the amount of any damages which the
         Underwriter has otherwise been required to pay by reason of such 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 Act) shall be entitled to contribution from any person who
         was not guilty of such fraudulent misrepresentation. The Underwriter's
         obligations in this subsection (d) to contribute are several in
         proportion to their respective underwriting obligations and not joint.

                  (e) The obligations of the Company under this Section shall be
         in addition to any liability which the Company may otherwise have and
         shall extend, upon the same terms and conditions, to each person, if
         any, who controls the Underwriter within the meaning of the Act; and
         the obligations of the Underwriter under this Section 7 shall be in
         addition to any liability which the Underwriter may otherwise have and


                                       12


         shall extend, upon the same terms and conditions, to each director of
         the Company, to each officer of the Company who has signed a
         Registration Statement and to each person, if any, who controls the
         Company within the meaning of the Act.

         8. Survival of Certain Representations and Obligations. The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the Underwriter 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
the Underwriter, the Company 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 or if
for any reason the purchase of the Offered Securities by the Underwriter is not
consummated, the Company 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 Underwriter pursuant to Section 7 shall remain in effect, and if
any Offered Securities have been purchased hereunder the representations and
warranties in Section 2 and all obligations under Section 5 shall also remain in
effect. If the purchase of the Offered Securities by the Underwriter is not
consummated for any reason other than solely because of the occurrence of any
event specified in clause (iii), (iv) or (v) of Section 6(c), the Company will
reimburse the Underwriter 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.

         9. Notices. All communications hereunder will be in writing and, if
sent to the Underwriter, will be mailed, delivered or sent by facsimile and
confirmed to Eleven Madison Avenue, New York, N.Y. 10010-3629, Attention:
Transactions Advisory Group, or, if sent to the Company, will be mailed,
delivered or sent by facsimile and confirmed to it at 1001 Louisiana Street,
Houston, Texas 77002, Attention: Legal Department.

         10. Successors. This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the officers
and directors and controlling persons referred to in Section 7, and no other
person will have any right or obligation hereunder.

         11. 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.

         12. 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 hereby submits 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.
