   As Representatives of the Several Underwriters,
     c/o Credit Suisse First Boston Corporation
     Eleven Madison Avenue
     New York, NY 10010-3629

Dear Sirs:

     1. Introductory. Spinnaker Exploration Company, a Delaware corporation (the
"Company"), proposes to issue and sell 5,000,000 shares ("Firm Securities") of
its common stock, par value $.01 per share ("Securities"), and also proposes to
issue and sell to the Underwriters, at the option of the Underwriters, an
aggregate of not more than 750,000 additional shares ("Optional Securities") of
its Securities as set forth below. The Firm Securities and the Optional
Securities are herein collectively called the "Offered Securities". The Company
hereby agrees with the several Underwriters named in Schedule A hereto
("Underwriters") as follows:

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

          (a) A registration statement (No. 333-72238), including a prospectus,
     relating to the Offered Securities has been filed with the Securities and
     Exchange Commission ("Commission") and has become effective. Such
     registration statement, as amended as of the date of this Agreement, is
     hereinafter referred to as the "Registration Statement", and the prospectus
     included in such Registration Statement, as supplemented to reflect the
     terms of offering of the Offered Securities, as first filed on or after the
     date of this Agreement with the Commission pursuant to and in accordance
     with Rule 424(b) ("Rule 424(b)") under the Securities Act of 1933 ("Act"),
     including all material incorporated by reference therein, is 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
     Registration Statement conformed in all material respects to the
     requirements of the 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, and on
     the date of this Agreement, the Registration Statement and the Prospectus
     conform in all material respects to the requirements of the Act and the
     Rules and Regulations, and neither of such documents includes any untrue
     statement of a material fact or omits to state any material fact required
     to be stated therein or necessary to make the statements therein not
     misleading, except that the foregoing does 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 Representatives, if
     any, specifically for use therein.

          (c) The Company has been duly incorporated and is an existing
     corporation in good standing under the laws of the State of Delaware, with
     power and authority (corporate and other) 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 so qualify would not have a material adverse effect on the
     condition (financial or other), business, properties or results of
     operations of the Company and its subsidiaries taken as a whole ("Material
     Adverse Effect").

          (d) Each subsidiary of the Company has been duly incorporated or
     otherwise organized and is an existing corporation or other entity in good
     standing under the laws of the jurisdiction of its incorporation or
     organization, with power and authority (corporate and other) to own its
     properties and conduct its business as described in the Prospectus; and
     each subsidiary of the Company is duly qualified to do business as a
     foreign corporation or other entity 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 so
     qualify would not have a Material Adverse Effect; all of the issued and
     outstanding capital stock or other ownership interest of each subsidiary of
     the Company has been duly authorized and validly issued and is fully paid
     and nonassessable; and, except as disclosed in the Prospectus, the capital
     stock or other ownership interest of each subsidiary owned by the Company,
     directly or through subsidiaries, is owned free from liens, encumbrances
     and defects.

          (e) The Offered Securities and all other outstanding shares of capital
     stock of the Company have been duly authorized; all outstanding shares of
     capital stock of the Company are, and, when the Offered Securities have
     been delivered and paid for in accordance with this Agreement on each
     Closing Date (as defined below), such Offered Securities will have been,
     validly issued, fully paid and nonassessable and will conform to the
     description thereof contained in the Prospectus; and the stockholders of
     the Company have no preemptive rights with respect to the Securities.

          (f) Except as disclosed in the Prospectus, there are no contracts,
     agreements or understandings between the Company and any person that would
     give rise to a valid claim against the Company or any Underwriter for a
     brokerage commission, finder's fee or other like payment in connection with
     this offering.

          (g) Except as disclosed in the Prospectus, there are no contracts,
     agreements or understandings between the Company and any person granting
     such person the right to require the Company to file a registration
     statement under the Act with respect to any securities of the Company owned
     or to be owned by such person or to require the Company to include such
     securities in the securities registered pursuant to the Registration
     Statement (the relevant provisions

                                       2



     of which have not been waived) or in any securities being registered
     pursuant to any other registration statement filed by the Company under the
     Act.

          (h) The Securities have been approved for listing on The New York
     Stock Exchange, subject to notice of issuance.

          (i) 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 such
     as may be required under state securities laws and except for consents,
     approvals, authorizations, orders or filings the failure to obtain or make
     would not have a Material Adverse Effect.

          (j) The execution, delivery and performance of this Agreement, and the
     issuance and sale of the Offered Securities will not result in a breach or
     violation of any of the terms and provisions of, or constitute a default
     under (i) 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 subsidiary of the Company or any of their properties, or
     any agreement or instrument to which the Company or any such subsidiary is
     a party or by which the Company or any such subsidiary is bound or to which
     any of the properties of the Company or any such subsidiary is subject, or
     (ii) the charter, by-laws or other organizational documents of the Company
     or any such subsidiary other than, in the case of clause (i), such
     breaches, violations or defaults that would not, individually or in the
     aggregate, have a Material Adverse Effect, and the Company has full
     corporate power and authority to authorize, issue and sell the Offered
     Securities as contemplated by this Agreement.

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

          (l) Except as described in the Prospectus, each of the Company and its
     subsidiaries has (i) good and indefeasible title to all its interests in
     its oil and gas properties, and title investigations have been carried out
     by or on behalf of the Company in accordance with good practice in the oil
     and gas industry in the areas in which the Company and its subsidiaries
     operate and (ii) good and indefeasible title to all other real property and
     marketable title to all other material properties and assets described in
     the Prospectus as owned by the Company or such subsidiary and valid,
     subsisting and enforceable leases for all properties and assets, real or
     personal, described in the Prospectus as leased by them, in each case free
     and clear of any imperfections of title, security interests, mortgages,
     pledges, liens, encumbrances or charges of any kind, other than those
     described in the Prospectus and those that could not, individually or in
     the aggregate, have a Material Adverse Effect.

          (m) The Company and its subsidiaries possess adequate certificates,
     authorities or permits issued by appropriate governmental agencies or
     bodies necessary to conduct the business now operated by them, except for
     such certificates, authorities or permits with respect to which the lack of
     possession would not, individually or in the aggregate, have a Material
     Adverse Effect, and have not received any notice of proceedings relating to
     the revocation or modification of any such certificate, authority or permit
     that, if determined adversely to the Company or any of its subsidiaries,
     would individually or in the aggregate have a Material Adverse Effect.

          (n) No labor dispute with the employees of the Company or any
     subsidiary exists or, to the knowledge of the Company, is imminent that
     might reasonably be expected to have a Material Adverse Effect.


                                       3



          (o) The Company and its subsidiaries own, possess or can acquire on
     reasonable terms, adequate trademarks, trade names and other rights to
     inventions, know-how, patents, copyrights, confidential information and
     other intellectual property (collectively, "intellectual property rights")
     necessary to conduct the business now operated by them, or presently
     employed by them, and have not received any notice of infringement of or
     conflict with asserted rights of others with respect to any intellectual
     property rights that, if determined adversely to the Company or any of its
     subsidiaries, would individually or in the aggregate have a Material
     Adverse Effect.

          (p) Except as disclosed in the Prospectus, neither the Company nor any
     of its 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 the Company is not aware of
     any pending investigation which might lead to such a claim.

          (q) 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 this Agreement, or which are otherwise material in the context of the
     sale of the Offered Securities; and, to the Company's knowledge, no such
     actions, suits or proceedings are threatened or contemplated.

          (r) The financial statements included or incorporated by reference in
     the Registration Statement and the Prospectus present fairly the 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 such financial statements have been prepared in conformity with the
     generally accepted accounting principles in the United States applied on a
     consistent basis.

          (s) Except as disclosed in the Prospectus, since the date of the
     latest audited financial statements included or incorporated by reference
     in the Prospectus there has been no material adverse change, nor any
     development or event involving a prospective material adverse change, in
     the condition (financial or other), business, properties or results of
     operations of the Company and its subsidiaries taken as a whole, and there
     has been no dividend or distribution of any kind declared, paid or made by
     the Company on any class of its capital stock.

          (t) The information on the basis of which the reserve estimates and
     related information included in the Registration Statement and the
     Prospectus or incorporated by reference therein that was prepared by the
     Company, its subsidiaries, Ryder Scott Company, L.P., independent oil and
     natural gas engineers, or any other person, is true and correct in all
     material respects.

          (u) The Company and each of its subsidiaries maintain a system of
     internal accounting controls sufficient to provide reasonable assurances
     that (i) transactions are executed in accordance with management's general
     or specific authorizations; (ii) transactions are recorded as necessary to
     permit preparation of financial statements in conformity with generally
     accepted accounting principles and to maintain asset accountability; (iii)
     access to assets is permitted only in accordance with management's general
     or specific authorization; and (iv) the recorded


                                       4



     accountability for assets is compared with the existing assets at
     reasonable intervals and appropriate action is taken with respect to any
     differences.

          (v) The Company and each of its subsidiaries are insured by insurers
     of recognized financial responsibility against such losses and risks and in
     such amounts as are prudent and customary in the businesses in which they
     are engaged; and neither the Company nor any of its subsidiaries have any
     reason to believe that they will not be able to renew their existing
     insurance coverage as and when such coverage expires or to obtain similar
     coverage from similar insurers as may be necessary to continue its business
     at a cost that would not materially and adversely affect the condition
     (financial or otherwise), business prospects, net worth or results of
     operations of the Company and its subsidiaries, except as described in or
     contemplated by the Prospectus.

          (w) The Company is not and, after giving effect to the offering and
     sale of the Offered Securities, will not be an "investment company" as
     defined in the Investment Company Act of 1940.

          (x) The Company has filed in a timely manner with the Commission each
     document required to be filed by it pursuant to the Securities Exchange Act
     of 1934, as amended (the "Exchange Act"), each such document at the time it
     was filed conformed in all material respects to the requirements of the
     Exchange Act and none of such documents contained an untrue statement of a
     material fact or omitted to state a 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. The Company files
     such reports with the Commission on the Electronic Data Gathering, Analysis
     and Retrieval (EDGAR) system.

     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
Underwriters, and the Underwriters agree, severally and not jointly, to purchase
from the Company, at a purchase price of $39.63 per share, the respective
numbers of Firm Securities set forth opposite the names of the Underwriters in
Schedule A hereto.

     The Company will deliver the Firm Securities to the Representatives for the
accounts of the Underwriters, against payment of the purchase price in Federal
(same day) funds by official bank check or checks or wire transfer to an account
at a bank acceptable to Credit Suisse First Boston Corporation ("CSFBC") drawn
to the order of Spinnaker Exploration Company at the office of Baker Botts
L.L.P., One Shell Plaza, 910 Louisiana, Houston, Texas 77002, at 9:00 A.M., New
York time, on April 3, 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 "First Closing Date". For purposes of Rule 15c6-1
under the Exchange Act, the First Closing Date (if later than the otherwise
applicable settlement date) shall be the settlement date for payment of funds
and delivery of securities for all the Offered Securities sold pursuant to the
offering. The certificates for the Firm Securities so to be delivered will be in
definitive form, in such denominations and registered in such names as CSFBC
requests and will be made available for checking and packaging at the office of
ComputerShare Investor Services, LLC, 2 North LaSalle Street, 3rd Floor,
Chicago, Illinois 60602 at least 24 hours prior to the First Closing Date.

     In addition, upon written notice from CSFBC given to the Company from time
to time not more than 30 days subsequent to the date of the Prospectus, the
Underwriters may purchase all or less than all of the Optional Securities at the
purchase price per Security to be paid for the Firm Securities. The Company
agrees to sell to the Underwriters the number of shares of Optional Securities
specified in such notice and the Underwriters agree, severally and not jointly,
to purchase such Optional Securities. Such Optional Securities shall be
purchased for the account of each Underwriter in the same proportion as the
number of shares of Firm Securities set forth opposite such Underwriter's name
bears to the total number of shares of Firm Securities (subject to adjustment by
CSFBC to eliminate fractions) and may be purchased by the


                                       5



Underwriters only for the purpose of covering over-allotments made in connection
with the sale of the Firm Securities. No Optional Securities shall be sold or
delivered unless the Firm Securities previously have been, or simultaneously
are, sold and delivered. The right to purchase the Optional Securities or any
portion thereof may be exercised from time to time and to the extent not
previously exercised may be surrendered and terminated at any time upon notice
by CSFBC to the Company.

     Each time for the delivery of and payment for the Optional Securities,
being herein referred to as an "Optional Closing Date", which may be the First
Closing Date (the First Closing Date and each Optional Closing Date, if any,
being sometimes referred to as a "Closing Date"), shall be determined by CSFBC
but shall be not later than five full business days after written notice of
election to purchase Optional Securities is given. The Company will deliver the
Optional Securities being purchased on each Optional Closing Date to the
Representatives for the accounts of the several Underwriters, against payment of
the purchase price in Federal (same day) funds by official bank check or checks
or wire transfer to an account at a bank acceptable to CSFBC drawn to the order
of Spinnaker Exploration Company, at the above office of Baker Botts L.L.P. The
certificates for the Optional Securities being purchased on each Optional
Closing Date will be in definitive form, in such denominations and registered in
such names as CSFBC requests upon reasonable notice prior to such Optional
Closing Date and will be made available for checking and packaging at the above
office of ComputerShare Investor Services, LLC at a reasonable time in advance
of such Optional Closing Date.

     4. Offering by Underwriters. It is understood that the several Underwriters
propose 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 several
Underwriters that:

          (a) The Company will file the Prospectus with the Commission pursuant
     to and in accordance with Rule 424(b)(5) not later than the second business
     day following the execution and delivery of this Agreement.

          (b) The Company will advise CSFBC promptly of any proposal to amend or
     supplement the Registration Statement or the Prospectus and will afford
     CSFBC a reasonable opportunity to comment on such proposed amendment or
     supplement; and the Company will also advise CSFBC promptly of the filing
     of any amendment or supplementation of the Registration Statement or the
     Prospectus and of the institution by the Commission of any stop order
     proceedings in respect of the Registration Statement or any part thereof
     and will use its reasonable 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 will promptly
     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, (c) nor the Underwriters' delivery
     of, any such amendment or supplement shall constitute a waiver of any of
     the conditions set forth in Section 6.

          (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
     securityholders an earnings statement


                                       6



     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 to the Representatives copies of the
     Registration Statement, six of which will be signed and will include all
     exhibits, each related preliminary prospectus supplement, and, so long as a
     prospectus relating to the Offered Securities is required to be delivered
     under the Act in connection with sales by any Underwriter or dealer, the
     Prospectus and all amendments and supplements to such documents, in each
     case in such quantities as CSFBC requests. The Prospectus shall be
     furnished on or prior to 3:00 P.M., New York time, on the business day
     following the execution and delivery of this Agreement. All other such
     documents should be furnished as soon as available. The Company will pay
     the expenses of printing and distributing to the Underwriters all such
     documents.

          (f) The Company will arrange for the qualification of the Offered
     Securities for sale under the laws of such jurisdictions as CSFBC
     reasonably designates and will continue such qualifications in effect so
     long as required for the distribution.

          (g) The Company will pay all expenses incident to the performance of
     its obligations under this Agreement, for any filing fees and other
     expenses (including fees and disbursements of counsel to the Underwriters)
     incurred in connection with qualification of the Offered Securities for
     sale under the laws of such jurisdictions as CSFBC designates and the
     printing of memoranda relating thereto, for the filing fee incident to, and
     the reasonable fees and disbursements of counsel to the Underwriters in
     connection with, the review by the National Association of Securities
     Dealers, Inc. of the Offered Securities, for any travel expenses of the
     Company's officers and employees and any other expenses of the Company in
     connection with attending or hosting meetings with prospective purchasers
     of the Offered Securities, for expenses incurred in distributing
     preliminary prospectuses and the Prospectus (including any amendments and
     supplements thereto) to the Underwriters.

          (h) For a period of 60 days after the date of the Prospectus, 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, any additional shares of its
     Securities or securities convertible into or exchangeable or exercisable
     for any shares of its Securities, or publicly disclose the intention to
     make any such offer, sale, pledge, disposition or filing, without the prior
     written consent of CSFBC, except grants of employee or director stock
     options, including pursuant to a stock purchase plan, pursuant to the terms
     of a plan in effect on the date hereof, issuances of Securities pursuant to
     the exercise of such options or the exercise of any other employee stock
     options outstanding on the date hereof or issuances of Securities pursuant
     to the Company's 401(k) plan as in effect on the date hereof.

     6. Conditions of the Obligations of the Underwriters. The obligations of
the several Underwriters to purchase and pay for the Firm Securities on the
First Closing Date and the Optional Securities to be purchased on each Optional
Closing Date will be subject to the accuracy of the representations and
warranties on the part of the Company herein, to the accuracy of the statements
of Company officers made pursuant to the provisions hereof, to the performance
by the Company of its obligations hereunder and to the following additional
conditions precedent:

          (a) The Representatives shall have received a letter, dated the date
     of delivery thereof (which shall be on or prior to the date of this
     Agreement), of Arthur Andersen LLP confirming that


                                       7



     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 examined by them
          and included in the Registration Statement 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 the unaudited financial
          statements included in the Registration Statement, if any;

               (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 included in the
               Registration Statement, if any, do not comply as to form in all
               material respects with the 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 for them to be in conformity with generally accepted
               accounting principles;

                    (B) 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

                    (C) for the period from the closing date of the latest
               statement of operations included in the Prospectus to the closing
               date of the latest available statement of operations read by such
               accountants there were any decreases, as compared with the
               corresponding period of the previous year and a period of
               corresponding length immediately preceding such period, in
               consolidated net sales or net operating income) in the total or
               per share amounts of consolidated net income.

               except in all cases set forth in clauses (B) and (C) 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 Registration Statement (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 included in material incorporated by
          reference into the Registration Statement shall be deemed included in
          the Prospectus for purposes of this subsection.


                                       8



          (b) The Prospectus shall have been filed with the Commission in
     accordance with the Rules and Regulations and Section 5(a) of this
     Agreement. Prior to any Closing Date, no stop order suspending the
     effectiveness of the Registration Statement shall have been issued and no
     proceedings for that purpose shall have been instituted or, to the
     knowledge of the Company or the Representatives, 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 condition (financial or other),
     business, properties or results of operations of the Company and its
     subsidiaries taken as one enterprise which, in the judgment of a majority
     in interest of the Underwriters including CSFBC, 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 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 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; (iv) any banking moratorium declared by
     U.S. Federal or New York authorities or a material disruption in commercial
     banking or securities settlement or clearance services in the United
     States; or (v) 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 Underwriters including
     CSFBC, 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 Representatives shall have received from Warburg, Pincus
     Ventures, L.P. and each person who is a director or officer of the Company
     who owns shares of Securities on the date of this Agreement an agreement to
     the effect that, for a period of 60 days after the date of the Prospectus,
     such person or entity will not offer, sell, contract to sell, pledge or
     otherwise dispose of, directly or indirectly, any shares of Securities or
     securities convertible into or exchangeable or exercisable for any shares
     of Securities, or publicly disclose the intention to make any such offer,
     sale, pledge or disposal, without the prior written consent of CSFBC.

          (e) The Representatives shall have received an opinion, dated such
     Closing Date, of Vinson & Elkins L.L.P., counsel for the Company, to the
     effect that:

               (i) The Company has been duly incorporated and is an existing

          qualified to do business as a foreign limited liability company in the
          States of Texas and Louisiana.

               (ii) The Offered Securities conform in all material respects to
          the description thereof contained in the Registration Statement and
          the Prospectus; the Offered Securities have been duly and validly
          authorized, and, when issued and delivered to and paid for by the
          Underwriters pursuant to this Agreement, will be validly issued, fully
          paid and nonassessable; stockholders of the Company are not entitled
          to preemptive rights under the Company's Certificate of


                                       9



          Incorporation or Bylaws or under the Delaware General Corporation Law
          or, to such counsel's knowledge, any contract to which the Company is
          a party in connection with the issuance of the Offered Securities; all
          outstanding shares of the capital stock of the Company (other than the
          Offered Securities) have been duly authorized and validly issued and
          are fully paid and nonassessable;

               (iii) Except as disclosed in the Prospectus, there are no
          contracts, agreements or understandings known to such counsel between
          the Company and any person granting such person the right to require
          the Company to file a registration statement under the Act with
          respect to any securities of the Company owned or to be owned by such
          person or to require the Company to include such securities in the
          securities registered pursuant to the Registration Statement (the
          relevant provisions of which have not been waived) or in any
          securities being registered pursuant to any other registration
          statement filed by the Company under the Act;

               (iv) 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 or sale of the Offered Securities by the
          Company, except such as have been obtained and made under the Act and
          such as may be required under state securities laws and except for
          consents, approvals, authorizations, orders or filings the failure to
          obtain or make would not have a Material Adverse Effect;

               (v) The execution, delivery and performance of this Agreement and
          the issuance and sale of the Offered Securities by the Company will
          not result in a breach or violation of any of the terms and provisions
          of, or constitute a default under, (i) any statute, any rule or, to
          the knowledge of such counsel, regulation or order of any governmental
          agency or body or any court having jurisdiction over the Company or
          any subsidiary of the Company or any of their properties (except that
          such counsel need not express any opinion with respect to federal or
          state securities laws or blue sky laws with respect to this
          paragraph), or any material agreement or instrument to which the
          Company or any such subsidiary is a party or by which the Company or
          any such subsidiary is bound or to which any of the properties of the
          Company or any such subsidiary is subject known to such counsel, or
          (ii) the charter, by-laws or other organizational documents of the
          Company or any such subsidiary, other than with respect to clause (i)
          such breaches, violations or defaults that would not, individually or
          in the aggregate, have a Material Adverse Effect, and the Company has
          full corporate power and authority to authorize, issue and sell the
          Offered Securities as contemplated by this Agreement;

               (vi) The Registration Statement was declared 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 such
          counsel have no reason to believe that the Registration Statement and
          the Prospectus, and each amendment or supplement thereto, as of their
          respective effective or issue dates, was not appropriately responsive
          in all material respects to the requirements of the Act and the Rules
          and Regulations; such counsel have no reason to believe that any part
          of the Registration Statement or any amendment thereto, as of its
          effective 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 or any amendment or supplement thereto, as of its issue
          date or as of such 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
          Prospectus or in the Company's most recent Annual Report on Form 10-K
          filed with the Commission under the captions "Business--PGS Data
          Agreement," "--Regulation," and "Description of Capital Stock" of
          statutes, legal and governmental proceedings and contracts and other
          documents are accurate in


                                       10



          all material respects and fairly presented; and such counsel do not
          know of any legal or governmental proceedings required to be described
          in the Registration Statement or 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 the
          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, schedules or other financial data or reserve information
          or information that pertains or relates to estimated natural resources
          reserves, estimated future net reserves therefrom or the discounted
          net present value of such estimated future net reserves contained in
          the Registration Statement or the Prospectus; and

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

          (f) The Representatives shall have received from Baker Botts L.L.P.,
     counsel for the Underwriters, 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 CSFBC 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 Representatives shall have received a certificate, dated such
     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, shall state that: the representations and
     warranties of the Company in this Agreement are true and correct; the
     Company has complied with all agreements and satisfied all conditions on
     its part to be performed or satisfied hereunder at or prior to such Closing
     Date; no stop order suspending the effectiveness of any Registration
     Statement has been issued and no proceedings for that purpose have been
     instituted or are contemplated by the Commission; and, subsequent to the
     date of the most recent financial statements incorporated by reference in
     the Prospectus, there has been no material adverse change in, nor any
     development or event that could be reasonably expected to have a material
     adverse effect on, the condition (financial or other), 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 Representatives shall have received a letter (unless Arthur
     Andersen LLP is unable or unwilling to deliver such a letter as a result of
     events affecting Arthur Andersen LLP generally and not as a result of (1)
     concerns or other matters specific to the Company or (2) the failure of the
     Company to use commercially reasonable efforts to engage Arthur Andersen
     LLP to deliver such letter to the Representatives and to provide Arthur
     Andersen LLP with all information necessary to deliver such letter), dated
     such Closing Date, of Arthur Andersen 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.

          (i) The Representatives shall have received from Ryder Scott Company,
     L.P., independent natural gas and oil engineers, letters dated,
     respectively, the date of this Agreement and the Closing Date, in form and
     substance satisfactory to the Representatives, each stating, as of the date
     of such letter (or, with respect to matters involving changes or
     developments since the respective dates as of which information regarding
     the natural gas and oil reserves and future net cash flows is given in the
     Prospectus, as of the date not more than three days prior to the date of
     such letter), the conclusions and findings of such firm with respect to the
     natural gas and oil reserves of the Company and such other matters as the
     Representatives reasonably may request.

          (j) If Arthur Andersen LLP is unable or unwilling to deliver a letter
     meeting the requirements of Section 6(a) of this Agreement on and as of the
     Closing Date, then the Representatives shall have received a certificate,
     dated such Closing Date, of the principal financial officer and the
     principal


                                       11



     accounting officer of the Company in which such officers shall confirm the
     substance of the provisions of Sections 6(a)(iii)(B) and 6(a)(iii)(C) of
     this Agreement to the extent and for the periods that Arthur Andersen LLP
     has not provided a letter to the Representatives covering such information.

     The Company will furnish the Underwriters with such conformed copies of
     such opinions, certificates, letters and documents as CSFBC reasonably
     requests. CSFBC may in its sole discretion waive on behalf of the
     Underwriters compliance with any conditions to the obligations of the
     Underwriters hereunder, whether in respect of an Optional Closing Date or
     otherwise.

     7. Indemnification and Contribution. (a) The Company will indemnify and
hold harmless each Underwriter, its partners, directors and officers and each
person, if any, who controls such Underwriter within the meaning of Section 15
of the Act, against any losses, claims, damages or liabilities, joint or
several, to which such 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 the Registration Statement,
the Prospectus, or any amendment or supplement thereto, or any related
preliminary prospectus supplement, 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 each Underwriter for any legal or other expenses reasonably
incurred by such 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 any Underwriter through CSFBC
specifically for use therein, it being understood and agreed that the only such
information furnished by any Underwriter consists of the information described
as such in subsection (b) below.

     (b) Each Underwriter will severally and not jointly 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 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 such Underwriter through CSFBC 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 Underwriter consists of
the following information in the Prospectus furnished on behalf of each
Underwriter: the concession and reallowance figures appearing in the fourth
paragraph and paragraphs nine and ten 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


                                       12



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 Underwriters 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 Underwriters 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 Underwriters 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 Underwriters.
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 Underwriters 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
Underwriter shall 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 such 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 Underwriters' 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 any Underwriter
within the meaning of the Act; and the obligations of the Underwriters under
this Section shall be in addition to any liability which the respective
Underwriters may otherwise have and shall extend, upon the same terms and
conditions, to each director of the Company, to each officer of the Company who
has signed the Registration Statement and to each person, if any, who controls
the Company within the meaning of the Act.

     8. Default of Underwriters. If any Underwriter or Underwriters default in
their obligations to purchase Offered Securities hereunder on either the First
or any Optional Closing Date and the aggregate number of shares of Offered
Securities that such defaulting Underwriter or Underwriters agreed but failed to
purchase does not exceed 10% of the total number of shares of Offered Securities
that the Underwriters are obligated to purchase on such Closing Date, then CSFBC
may make arrangements satisfactory to the Company for the purchase of such
Offered Securities by other persons, including any of the Underwriters, but if
no such arrangements are made by such Closing Date, then the non-defaulting
Underwriters shall be


                                       13



obligated severally, in proportion to their respective commitments hereunder, to
purchase the Offered Securities that such defaulting Underwriters agreed but
failed to purchase on such Closing Date. If any Underwriter or Underwriters so
default and the aggregate number of shares of Offered Securities with respect to
which such default or defaults occur exceeds 10% of the total number of shares
of Offered Securities that the Underwriters are obligated to purchase on such
Closing Date and arrangements satisfactory to CSFBC and the Company for the
purchase of such Offered Securities by other persons are not made within 36
hours after such default, then this Agreement will terminate without liability
on the part of any non-defaulting Underwriter or the Company, except as provided
in Section 9 (provided that if such default occurs with respect to Optional
Securities after the First Closing Date, then this Agreement will not terminate
as to the Firm Securities or any Optional Securities purchased prior to such
termination). As used in this Agreement, the term "Underwriter" includes any
person substituted for an Underwriter under this Section. Nothing herein will
relieve a defaulting Underwriter from liability for its default.

     9. Survival of Certain Representations and Obligations. The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the several Underwriters 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 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 pursuant
to Section 8 or if for any reason the purchase of the Offered Securities by the
Underwriters 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 Underwriters 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 Underwriters 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) or (v) of Section 6(c), the Company
will reimburse the Underwriters for all out-of-pocket expenses (including
reasonable 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 Underwriters, will be mailed, delivered, telegraphed, or sent by
facsimile transmission with receipt confirmed to the Representatives, c/o Credit
Suisse First Boston Corporation, Eleven Madison Avenue, New York, NY 10010-3629,
Attention: Transactions Advisory Group, or, if sent to the Company, will be
mailed, delivered or telegraphed and confirmed to it at 1200 Smith Street, Suite
800, Houston, Texas 77002, Attention: Roger L. Jarvis; provided, however, that
any notice to an Underwriter pursuant to Section 7 will be mailed, delivered or
telegraphed and confirmed to such Underwriter.

     11. 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.

     12. Representation. CSFBC will act for the several Underwriters in
connection with the transactions contemplated by this Agreement, and any action
under this Agreement taken by CSFBC will be binding upon all the Underwriters.

     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.


                                       14
