conversion thereof) shall bear the following legend:

         ANY PURCHASER OF THIS NOTE FROM IT OF THE RESALE RESTRICTIONS REFERRED
         TO IN (A) ABOVE."

2.       Agreements to Sell and Purchase. On the basis of the representations,
         warranties and covenants contained in this Agreement, and subject to
         the terms and conditions contained herein, the Issuers agree to issue
         and sell to the Initial Purchasers, and each Initial Purchaser agrees,
         severally and not jointly, to purchase from the Issuers, the principal
         amounts of Series A Notes set forth opposite the name of such Initial
         Purchaser on Schedule B hereto at a purchase price equal to 98.25% of
         the principal amount thereof (the "Purchase Price").

3.       Terms of Offering. The Initial Purchasers have advised the Issuers that
         the Initial Purchasers will make offers (the "Exempt Resales") of the
         Series A Notes purchased hereunder on the terms set forth in the
         Offering Memorandum, as amended or supplemented, solely to (i) persons
         whom the Initial Purchasers reasonably believe to be "qualified
         institutional buyers" as defined in Rule 144A under the Act ("QIBs")
         and (ii) persons permitted to purchase the Series A Notes in offshore
         transactions in reliance upon Regulation S under the Act (each, a
         "Regulation S Purchaser") (such persons specified in clauses (i) and
         (ii) being referred to herein as the "Eligible Purchasers"). The
         Initial Purchasers will offer the Series A Notes to Eligible Purchasers
         initially at a price equal to 100% of the principal amount thereof.

         Holders (including subsequent transferees) of the Series A Notes will
have the registration rights set forth in the registration rights agreement (the
"Registration Rights Agreement"), to be dated as of the Closing Date, in
substantially the form of Exhibit A hereto, for so long as such Series A Notes
constitute "Transfer Restricted Securities" (as defined in the Registration
Rights Agreement). Pursuant to the Registration Rights Agreement, the Issuers
and the Subsidiary Guarantors will agree to file with the Securities and
Exchange Commission (the "Commission") under the circumstances set forth
therein, (i) a registration statement under the Act (the "Exchange Offer
Registration Statement") relating to the Issuers' 6 1/4% Series B Senior Notes
due 2010 (the "Series B Notes"), and the guarantees thereof by each of the
Subsidiary Guarantors (the "Series B Guarantees") to be offered in exchange for
the Series A Notes and the Series A Guarantees thereof (such offer to exchange
being referred to as the "Exchange Offer") and (ii) a shelf registration
statement pursuant to Rule 415 under the Act (the "Shelf Registration Statement"
and, together with the Exchange Offer Registration Statement, the "Registration
Statements") relating to the resale by certain holders of the Series A Notes and
to use its best


                                       3

efforts to cause such Registration Statements to be declared and remain
effective and usable for the periods specified in the Registration Rights
Agreement and to consummate the Exchange Offer. This Agreement, the Indenture,
the Notes, the Guarantees and the Registration Rights Agreement are hereinafter
sometimes referred to collectively as the "Operative Documents."

4.       Delivery and Payment.

         (a) Delivery of, and payment of the Purchase Price for, the Series A
         Notes shall be made at the offices of Akin, Gump, Strauss, Hauer &
         Feld, L.L.P., 1900 Pennzoil Place South Tower, 711 Louisiana Street,

         York City time, on July 3, 2003 or at such other time on the same date
         or such other date as shall be agreed upon by the Initial Purchasers
         and the Issuers in writing. The time and date of such delivery and the
         payment for the Series A Notes are herein called the "Closing Date."

         (b) One or more of the Series A Notes in definitive global form,
         registered in the name of Cede & Co., as nominee of the Depository
         Trust Company ("DTC"), having an aggregate principal amount
         corresponding to the aggregate principal amount of the Series A Notes
         (collectively, the "Global Note"), shall be delivered by the Issuers to
         the Initial Purchasers (or as the Initial Purchasers direct) in each
         case with any transfer taxes thereon duly paid by the Issuers against
         payment by the Initial Purchasers of the Purchase Price thereof by wire

5.       Agreements of the Issuers and the Subsidiary Guarantors. Each of the
         Partnership, GulfTerra Finance and the Subsidiary Guarantors hereby
         agrees with the Initial Purchasers as follows:

         (a) To advise the Initial Purchasers promptly and, if requested by the
         Initial Purchasers, to confirm such advice in writing, (i) of the
         issuance by any state securities commission of any stop order
         suspending the qualification or exemption from qualification of any
         Series A Notes for offering or sale in any jurisdiction designated by
         the Initial Purchasers pursuant to Section 5(e) hereof, or the
         initiation of any proceeding by any state securities commission or any
         other federal or state regulatory authority for such purpose and (ii)
         of the happening of any event during the period referred to in Section
         5(c) below that makes any statement of a material fact made in the
         Offering Memorandum untrue or that requires any additions to or changes
         in the Offering Memorandum in order to make the statements therein not
         misleading. The Issuers and the Subsidiary Guarantors shall use their
         best efforts to prevent the issuance of any stop order or order
         suspending the qualification or exemption of any Series A Notes under
         any state securities or Blue Sky laws and, if at any time any state
         securities commission or other federal or state regulatory authority
         shall issue an order suspending the qualification or exemption of any
         Series A Notes under any state securities or Blue Sky laws, the Issuers
         and the Subsidiary


                                       4

         Guarantors shall use their best efforts to obtain the withdrawal or
         lifting of such order at the earliest possible time;

         (b) To furnish the Initial Purchasers and those persons identified by
         the Initial Purchasers to the Issuers as many copies of the Offering
         Memorandum, and any amendments or supplements thereto, as the Initial
         Purchasers may reasonably request for the time period specified in
         Section 5(c). Subject to the Initial Purchasers' compliance with its
         representations and warranties and agreements set forth in Section 7
         hereof, the Issuers consent to the use of the Offering Memorandum, and
         any amendments and supplements thereto required pursuant hereto, by the
         Initial Purchasers in connection with Exempt Resales;

         (c) At any time prior to the completion of the initial offering of the
         Series A Notes and in connection with market-making activities of the
         Initial Purchasers for so long as any Series A Notes are outstanding,
         (i) not to make any amendment or supplement to the Offering Memorandum
         of which the Initial Purchasers shall not previously have been advised
         or to which the Initial Purchasers shall reasonably object after being
         so advised, provided, that this clause (i) shall not apply to any
         filing by the Partnership of an Annual Report on Form 10-K, Quarterly
         Report on Form 10-Q or Current Report on Form 8-K with respect to (A)
         matters unrelated to the Series A Notes and the offering or exchange
         thereof or (B) a press release permitted by Rule 135c under the Act,
         and (ii) to prepare promptly upon the Initial Purchasers' reasonable
         request, any amendment or supplement to the Offering Memorandum which
         may be necessary or advisable in connection with such Exempt Resales or
         such market-making activities;

         (d) If, during the period referred to in Section 5(c) above, any event
         shall occur or condition shall exist as a result of which, in the
         opinion of counsel to the Initial Purchasers, it becomes necessary to
         amend or supplement the Offering Memorandum in order to make the
         statements therein, in the light of the circumstances when such
         Offering Memorandum is delivered to an Eligible Purchaser, not
         misleading, or if, in the opinion of counsel to the Initial Purchasers,
         it is necessary to amend or supplement the Offering Memorandum to
         comply with any applicable law, forthwith to prepare, subject to
         Section 5(c), an appropriate amendment or supplement to such Offering
         Memorandum so that the statements therein, as so amended or
         supplemented, will not, in the light of the circumstances when it is so
         delivered, be misleading, or so that such Offering Memorandum will
         comply with applicable law, and to furnish to the Initial Purchasers
         and such other persons as the Initial Purchasers may designate such
         number of copies thereof as the Initial Purchasers may reasonably
         request;

         (e) Prior to the sale of all Series A Notes pursuant to Exempt Resales
         as contemplated hereby, to cooperate with the Initial Purchasers and
         counsel to the Initial Purchasers in connection with the registration
         or qualification of the Series A Notes for offer and sale to the
         Initial Purchasers and pursuant to Exempt Resales under the securities
         or Blue Sky laws of such jurisdictions as the Initial Purchasers may
         request and to continue such registration or qualification in effect so
         long as required for Exempt Resales and to file such consents to
         service of process or other documents as may be necessary in order to
         effect such registration or qualification; provided, however, that
         neither the Issuers nor


                                       5

         any Subsidiary Guarantor shall be required in connection therewith to
         qualify as a foreign partnership, limited liability company, trust or
         corporation in any jurisdiction in which it is not now so 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
         relating to the Offering Memorandum or Exempt Resales, in any
         jurisdiction in which it is not now so subject;

         (f) For so long as the Series A Notes are outstanding, to furnish or
         make available to the Initial Purchasers copies of any annual reports,

         is a party or by which the Partnership or any of its Restricted
         Subsidiaries or GulfTerra Finance or their respective property is bound
         or (v) result in the termination, suspension or revocation of any
         existing Authorization (as defined below) of the Partnership or any of
         its Restricted Subsidiaries or GulfTerra Finance, or result in any
         other impairment of the rights of the


                                       13

         holder of any such Authorization, except (other than in the case of
         clause (ii) above with respect to Organizational Documents) to the
         extent they could reasonably be expected not to have a Material Adverse
         Effect.

         (r) No action, suit or governmental proceedings by or before any court
         or governmental agency, authority or body is pending or, to our
         knowledge, threatened to which the Partnership or any of its Restricted
         Subsidiaries or GulfTerra Finance is or could be a party or to which
         any of their respective property is or could be subject, except for
         such proceedings which, singly or in the aggregate, could reasonably be
         expected not to result in a Material Adverse Effect and except as set
         forth in the Offering Memorandum.

         (s) The Partnership, its Restricted Subsidiaries and GulfTerra Finance
         are (i) in compliance with any and all foreign, federal, state or local
         law or regulation relating to the protection of human health and
         safety, the environment or hazardous or toxic substances or wastes,
         pollutants or contaminants ("Environmental Laws"), (ii) have received
         and are in compliance with all permits, licenses or other approvals
         required of them under applicable Environmental Laws to conduct their
         respective businesses and (iii) have not received notice of any actual
         or potential liability under the Environmental Laws, in the case of (i)
         through (iii), except where such non-compliance or liability, singly or
         in the aggregate, could reasonably be expected not to result in a
         Material Adverse Effect. None of the Partnership, its Restricted
         Subsidiaries or GulfTerra Finance has been named as a "potentially
         responsible party" under the Comprehensive Environmental Response,
         Compensation, and Liability Act of 1980, as amended ("CERCLA"). The
         Partnership, its Restricted Subsidiaries and GulfTerra Finance are not
         in violation of any provisions of the Employee Retirement Income
         Security Act of 1974, as amended ("ERISA"), or any provisions of the
         Foreign Corrupt Practices Act or the rules and regulations promulgated
         thereunder, except for such violations which, singly or in the
         aggregate, could reasonably be expected not to result in a Material
         Adverse Effect.

         (t) There are no costs or liabilities associated with Environmental
         Laws (including, without limitation, any capital or operating
         expenditures required for clean-up, closure of properties or compliance
         with Environmental Laws or any Authorization, any related constraints
         on operating activities and any potential liabilities to third parties)
         which, singly or in the aggregate, could reasonably be expected to
         result in a Material Adverse Effect.

         (u) Each of the Partnership and its Restricted Subsidiaries and
         GulfTerra Finance has such permits, licenses, consents, exemptions,
         franchises, authorizations and other approvals (each, an
         "Authorization") of, and has made all filings with and notices to, all
         governmental or regulatory authorities and self-regulatory
         organizations and all courts and other tribunals, including without
         limitation, under any applicable Environmental Laws, as are necessary
         to own, lease, license and operate its respective properties and to
         conduct its business, except where the failure to have any such
         Authorization or to make any such filing or notice could, singly or in
         the aggregate, reasonably be expected not to have a Material Adverse
         Effect. Each such Authorization is valid and in full force and effect
         and each of the Partnership and its Restricted Subsidiaries and
         GulfTerra Finance is in compliance with all the terms and conditions
         thereof and with the rules and


                                       14

         regulations of the authorities and governing bodies having jurisdiction
         with respect thereto; and no event has occurred (including, without
         limitation, the receipt of any notice from any authority or governing
         body) which allows or, after notice or lapse of time or both, would
         allow, revocation, suspension or termination of any such Authorization
         or results or, after notice or lapse of time or both, would result in
         any other impairment of the rights of the holder of any such
         Authorization; and such Authorizations contain no restrictions that are
         burdensome to the Partnership or any of its Restricted Subsidiaries or
         GulfTerra Finance; except where such failure to be valid and in full
         force and effect or to be in compliance, the occurrence of any such
         event or the presence of any such restriction could, singly or in the
         aggregate, reasonably be expected not to have a Material Adverse
         Effect.

         (v) Each of the Partnership and its Restricted Subsidiaries and
         GulfTerra Finance owns or leases all such properties as are necessary
         to the conduct of its operations as presently conducted, except where
         the lack of ownership or leasing would not, individually or in the
         aggregate, have a Material Adverse Effect.

         (w) Each of the Partnership and its Restricted Subsidiaries and
         GulfTerra Finance has, or at the Closing Date will have, such consents,
         easements, rights-of-way or licenses from any person ("rights-of-way")
         as are necessary to conduct its business in the manner described in the
         Offering Memorandum, subject to such qualifications as may be set forth
         in the Offering Memorandum and except for such rights-of-way which, if
         not obtained, could, singly or in the aggregate, reasonably be expected
         not to have a Material Adverse Effect; each of the Partnership and its
         subsidiaries and GulfTerra Finance has, or at the Closing Date will
         have, fulfilled and performed all its material obligations with respect
         to such rights-of-way and no event has occurred which allows, or after
         notice or lapse of time would allow, revocation or termination thereof
         or would result in any impairment of the rights of the holder of any
         such rights-of-way, except for such revocations, terminations and
         impairments that could reasonably be expected not to have a Material
         Adverse Effect, subject in each case to such qualifications as may be
         set forth in the Offering Memorandum; and except as described in the
         Offering Memorandum, none of such rights-of-way contains any
         restriction that is materially burdensome to the Partnership and its
         subsidiaries and GulfTerra Finance considered as a whole.

         financial statements and supporting schedules included in the Offering
         Memorandum are independent public accountants with respect to the

         position of the Partnership and its subsidiaries (including GulfTerra
         Finance) on the basis stated in the Offering Memorandum at the
         respective dates or for the respective periods to


                                       15

         which they apply; such statements and related schedules and notes have
         been prepared in accordance with generally accepted accounting
         principles consistently applied throughout the periods involved, except
         as disclosed therein; and the other financial and statistical
         information and data set forth in the Offering Memorandum (and any
         amendment or supplement thereto) are, in all material respects,
         accurately presented and prepared on a basis consistent with such
         financial statements and the books and records of the Partnership and
         GulfTerra Finance.

         (z) The pro forma financial statements included in the Offering
         Memorandum have been prepared on a basis consistent with the historical
         financial statements of the Partnership and its subsidiaries and
         GulfTerra Finance and give effect to assumptions used in the
         preparation thereof on a reasonable basis and in good faith and present
         fairly the historical transactions described therein; and such pro
         forma financial statements comply as to form in all material respects
         with the requirements applicable to pro forma financial statements
         included in registration statements on Form S-3 under the Act. The

         in the Offering Memorandum are, in all material respects, accurately
         presented and prepared on a basis consistent with the pro forma
         financial statements.

         (aa) Neither of the Issuers nor any of the Partnership's Restricted
         Subsidiaries is or, after giving effect to the offering and sale of the
         Series A Notes and the application of the net proceeds thereof as
         described in the Offering Memorandum, neither of the Issuers, will be,
         an "investment company," as such term is defined in the Investment
         Company Act of 1940, as amended or 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.

         (bb) There are no contracts, agreements or understandings between the
         Issuers or any Subsidiary Guarantor, on the one hand, and any person,
         on the other hand, granting such person the right to require the
         Issuers or such Subsidiary Guarantor to file a registration statement
         under the Act with respect to any securities of the Issuers or such
         Subsidiary Guarantor other than the rights (i) of the General Partner
         and its affiliates in Section 6.14 of the Partnership Agreement and in
         the registration rights agreement executed in connection with the
         November 2002 acquisition by the Partnership of the San Juan assets
         (the "Series C RRA"); (ii) of EPEC Deepwater Gathering Company ("EPEC")
         and its successors pursuant to a registration rights agreement between
         EPEC and the Partnership executed in connection with the acquisition by
         the Partnership of an additional interest in Viosca Knoll Gathering
         Company; (iii) of Crystal Gas Storage, Inc. pursuant to the
         registration rights agreement between Crystal Gas Storage, Inc. and the
         Partnership which was executed in connection with the acquisition by

         that with respect to (i), (ii) and (iii) above, the General Partner,
         EPN Investments, Sabine I, Sabine II and DeepTech have waived such
         rights with respect to any Registration Statement filed pursuant to the
         Registration Rights Agreement; (iv) granted under the Credit Facility,
         the GulfTerra Holding Term Loan and related agreements; and (v) granted
         under the Registration Rights Agreement. There are no contracts,
         agreements or understandings between the Issuers or any Subsidiary
         Guarantor, on the one hand, and any person, on the other hand, granting
         such person the


                                       16

         right to require the Issuers or such Subsidiary Guarantor to include
         such securities with the Notes and Guarantees registered pursuant to
         any Registration Statement, other than the rights of the General
         Partner and its affiliates in Section 6.14 of the Partnership Agreement
         (which rights have been waived with respect to any Registration
         Statement filed pursuant to the Registration Rights Agreement).

         (cc) Neither the Partnership nor any of its subsidiaries nor GulfTerra
         Finance nor any agent thereof acting on the behalf of them has taken,
         and none of them will take, any action that might cause this Agreement
         or the issuance or sale of the Series A Notes to violate Regulation T
         (12 C.F.R. Part 220), Regulation U (12 C.F.R. Part 221) or Regulation X
         (12 C.F.R. Part 224) of the Board of Governors of the Federal Reserve
         System.

         (dd) No "nationally recognized statistical rating organization" as such
         term is defined for purposes of Rule 436(g)(2) under the Act (i) has
         imposed (or has informed the Issuers or any Subsidiary Guarantor that
         it is considering imposing) any condition (financial or otherwise) on
         the Issuers' or any Subsidiary Guarantor's retaining any rating
         assigned to the Issuers or any Subsidiary Guarantor, any securities of
         the Issuer or any Subsidiary Guarantor or (ii) has indicated to the
         Issuers or any Subsidiary Guarantor that it is considering (a) 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 so assigned or (b) any change in the outlook for any rating
         of the Issuers, any Subsidiary Guarantor or any securities of the
         Issuers or any Subsidiary Guarantor, other than, in the case of this
         cause (ii), any such downgrading, suspension, withdrawal, review or
         change that has been publicly announced by such organization as of the
         time of the execution of this Agreement.

         (ee) Since the respective dates as of which information is given in the
         Offering Memorandum other than as set forth in the Offering Memorandum
         (exclusive of any amendments or supplements thereto subsequent to the
         date of this Agreement), (i) there has not occurred any material
         adverse change or any development involving a prospective material
         adverse change in the condition, financial or otherwise, or the
         earnings, business, management or operations of the Partnership and its
         subsidiaries and GulfTerra Finance, taken as a whole, (ii) there has
         not been any material adverse change or any development involving a
         prospective material adverse change in the capital stock, limited
         liability company interests or partnership units, as applicable, or in
         the long-term debt of the Partnership or any of its subsidiaries or
         GulfTerra Finance and (iii) neither the Partnership, any of its
         subsidiaries nor GulfTerra Finance has incurred any material liability
         or obligation, direct or contingent.

         (ff) The Offering Memorandum, as of its date, contains all the
         information specified in, and meets all of the requirements of, Rule
         144A(d)(4) under the Act.

         (gg) The Offering Memorandum, as of its date, contains all of the
         information specified in, and complies in all material respects with,
         the applicable requirements of the Act as if such document were filed
         using a registration statement on Form S-3.


                                       17

         (hh) Upon execution and delivery by the parties thereto, the Indenture
         will comply as to form in all material respects with the requirements
         of the TIA, and the rules and regulations of the Commission applicable
         to an indenture which is qualified thereunder. It is not necessary in
         connection with the offer, sale and delivery of the Series A Notes to
         the Initial Purchasers in the manner contemplated by this Agreement or
         in connection with the initial placement of the Series A Notes by the
         Initial Purchasers in the manner contemplated by the Offering
         Memorandum pursuant to Exempt Resales to qualify the Indenture under
         the TIA.

         (ii) The statements under the captions "Description of Notes,"
         "Description of Other Indebtedness," "United States Federal Income and
         Estate Tax Considerations" and "Plan of Distribution" in the Offering
         Memorandum, insofar as such statements purport to constitute a summary
         of the legal matters, documents or proceedings referred to therein,
         fairly present in all material respects such legal matters, documents
         and proceedings.

         (jj) When the Series A Notes and the Series A Guarantees are issued and
         delivered pursuant to this Agreement, neither the Series A Notes nor
         the Series A Guarantees will be of the same class (within the meaning
         of Rule 144A under the Act) as any security of the Issuers or the
         Subsidiary Guarantors that is listed on a national securities exchange
         registered under Section 6 of the Exchange Act or that is quoted in a
         United States automated inter-dealer quotation system.

         (kk) No form of general solicitation or general advertising (as defined
         in Regulation D under the Act) was used by the Issuers, the Subsidiary
         Guarantors or any of their respective representatives (other than the
         Initial Purchasers, as to whom the Issuers and the Subsidiary
         Guarantors make no representation) in connection with the offer and
         sale of the Series A Notes contemplated hereby, including, but not
         limited to, articles, notices or other communications published in any
         newspaper, magazine, or similar medium or broadcast over television or
         radio, or any seminar or meeting whose attendees have been invited by
         any general solicitation or general advertising. No securities of the
         same class as the Series A Notes have been issued and sold by the
         Issuers within the six-month period immediately prior to the date
         hereof.

         (ll) None of the Issuers, the Subsidiary Guarantors nor any of their
         respective affiliates or any person acting on its or their behalf
         (other than the Initial Purchasers, as to whom the Issuers and the
         Subsidiary Guarantors make no representation) has engaged or will
         engage in any directed selling efforts within the meaning of Regulation
         S under the Act ("Regulation S") with respect to the Series A Notes or
         the Series A Guarantees.

         (mm) The Issuers, the Subsidiary Guarantors and their respective
         affiliates and all persons acting on their behalf (other than the
         Initial Purchasers, as to whom the Issuers and the Subsidiary
         Guarantors make no representation) have complied with and will comply
         with the offering restrictions requirements of Regulation S in
         connection with the offering of the Series A Notes outside the United
         States and, in connection therewith, the Offering Memorandum will
         contain the disclosure required by Regulation S.

         (nn) The Partnership is a "reporting issuer," as defined in Rule 902
         under the Act.


                                       18

         (oo) The Series A Notes offered and sold in reliance on Regulation S
         have been and will be offered and sold only in offshore transactions.

         (pp) The sale of the Series A Notes pursuant to Regulation S is not
         part of a plan or scheme to evade the registration provisions of the
         Act.

         (qq) No registration under the Act of the Series A Notes or the Series
         A Guarantees is required for the sale of the Series A Notes and the
         Series A Guarantees to the Initial Purchasers as contemplated hereby or
         for the Exempt Resales assuming the accuracy of the Initial Purchasers'
         representations and warranties and agreements set forth in Section 7
         hereof.

         (rr) Each certificate signed by any officer of the Issuers or any
         Subsidiary Guarantor and delivered to the Initial Purchasers or counsel
         for the Initial Purchasers shall be deemed to be a representation and
         warranty by the Issuers or such Subsidiary Guarantor to the Initial
         Purchasers as to the matters covered thereby.

         (ss) Except as otherwise set forth in the Offering Memorandum or such
         as are not material to the business, prospects, financial condition or
         results of operations of the Partnership and its subsidiaries (taken as
         a whole), and except for liens created by operation and maintenance
         agreements, space lease agreements and other similar types of
         agreements ordinary and customary to the operations of the General
         Partner, the Partnership and its subsidiaries, the Partnership and the
         Subsidiary Guarantors have good and defensible title to their interests
         in their oil and gas properties.

         (tt) The information which was supplied by the Partnership to
         Netherland, Sewell & Associates, Inc. ("Netherland & Sewell"),
         independent petroleum engineers, for purposes of evaluating the oil and
         gas reserves of the Partnership and the Subsidiary Guarantors as of
         March 27, 2003, including, without limitation, production, costs of
         operation and development, current prices for production, agreements
         relating to current and future operations and sales of production, was
         true and correct in all material respects on the dates such estimates
         were made and such information was supplied and was prepared in
         accordance with customary industry practices, as indicated in the
         letter of Netherland & Sewell dated January 28, 2002 (the "Netherland &
         Sewell Letter"); Netherland & Sewell was, as of the date of the
         Netherland & Sewell Letter, and is, as of the date hereof, independent
         with respect to the Partnership and the Subsidiary Guarantors; other
         than normal production of the reserves and intervening spot market
         product price fluctuations, the Partnership is not aware of any facts
         or circumstances that would result in a materially adverse change in
         the reserves, or the present value of future net cash flows therefrom,
         as described in the Offering Memorandum and as reflected in the
         Netherland & Sewell Letter and the reserve report referenced therein;
         estimates of such reserves and present values as described in the
         Offering Memorandum and reflected in the Netherland & Sewell Letter and
         the reserve report referenced therein comply in all material respects
         to the applicable requirements of Regulation S-X and Industry Guide 2
         under the Securities Act.


                                       19

         (uu) The Partnership 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 Partnership nor
         any of its subsidiaries (i) has received notice from any insurer or
         agent of such insurer that substantial capital improvements or other
         material expenditures will have to be made in order to continue such
         insurance or (ii) has any reason to believe that it will not be able to
         renew its existing insurance coverage as and when such coverage expires
         or to obtain similar coverage from similar insurers at a cost that
         could reasonably be expected not to have a Material Adverse Effect;

         (vv) Except as disclosed in the Offering Memorandum, no relationship,
         direct or indirect, exists between or among the Partnership or any of
         its subsidiaries on the one hand, and the directors, officers,
         stockholders, customers or suppliers of the Partnership or any of its
         subsidiaries, on the other hand, which would be required by the Act to
         be described in the Offering Memorandum if the Offering Memorandum were
         a prospectus included in a registration statement on Form S-1 filed
         with the Commission.

         (ww) There is no (i) significant unfair labor practice complaint,
         grievance or arbitration proceeding pending or threatened against the
         Partnership or any of its subsidiaries before the National Labor
         Relations Board or any state or local labor relations board, (ii)
         strike, labor dispute, slowdown or stoppage pending or threatened
         against the Partnership or any of its subsidiaries or (iii) union
         representation question existing with respect to the employees of the
         Partnership or any of its subsidiaries, except in the case of clauses
         (i), (ii) and (iii) for such actions which, singly or in the aggregate,
         could reasonably be expected not to have a Material Adverse Effect. To
         the best knowledge of the Partnership, no collective bargaining
         organizing activities are taking place with respect to the Partnership
         or any of its subsidiaries.

         (xx) The Issuers and each of their subsidiaries maintain a system of
         internal accounting controls sufficient to provide reasonable assurance
         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 accountability for assets is compared with the existing assets

         any differences.

         each of their subsidiaries in any jurisdiction have been filed, other
         than those filings being contested in good faith, and all material
         taxes, including withholding taxes, penalties and interest,
         assessments, fees and other charges due pursuant to such returns or
         pursuant to any assessment received by the Issuers or any of their
         subsidiaries have been paid, other than those being contested in good
         faith and for which adequate reserves have been provided. There are no
         transfer taxes or other similar fees or charges under Federal law or
         the laws of any state, or any political subdivision thereof, required
         to paid in connection with the execution and delivery of this Agreement
         or the issuance and sale of the Notes.


                                       20

         (zz) All indebtedness of the Partnership that will be repaid with the
         proceeds of the issuance and sale of the Series A Notes was incurred,
         and the indebtedness represented by the Series A Notes is being
         incurred, for proper purposes and in good faith and each of the Issuers
         and the Subsidiary Guarantors was, at the time of the incurrence of
         such indebtedness that will be repaid with the proceeds of the issuance
         and sale of the Series A Notes, and will be on the Closing Date (after
         giving effect to the application of the proceeds from the issuance of
         the Series A Notes) solvent, and had at the time of the incurrence of
         such indebtedness that will be repaid with the proceeds of the issuance
         and sale of the Series A Notes and will have on the Closing Date (after
         giving effect to the application of the proceeds from the issuance of
         the Series A Notes) sufficient capital for carrying on their respective
         business and were, at the time of the incurrence of such indebtedness
         that will be repaid with the proceeds of the issuance and sale of the
         Series A Notes, and will be on the Closing Date (after giving effect to
         the application of the proceeds from the issuance of the Series A
         Notes) able to pay their respective debts as they mature.

         (aaa) No action has been taken and no law, statute, rule or regulation
         or order has been enacted, adopted or issued by any governmental agency
         or body which prevents the execution, delivery and performance of any
         of the Operative Documents, or the issuance of the Series A Notes or
         the Series A Guarantees, or suspends the sale of the Series A Notes or
         the Series A Guarantees in any jurisdiction referred to in Section
         5(e); and no injunction, restraining order or other order or relief of
         any nature by a federal or state court or other tribunal of competent
         jurisdiction has been issued with respect to the Issuers or any of
         their subsidiaries which would prevent or suspend the issuance or sale
         of the Series A Notes or the Series A Guarantees in any jurisdiction
         referred to in Section 5(e).

         The Issuers acknowledge that the Initial Purchasers and, for purposes
of the opinions to be delivered to the Initial Purchasers pursuant to Section 9
hereof, counsel to the Issuers and the Subsidiary Guarantors and counsel to the
Initial Purchasers will rely upon the accuracy and truth of the foregoing
representations and hereby consents to such reliance.

         (b) Such Initial Purchaser (A) is not acquiring the Series A Notes with
         a view to any distribution thereof or with any present intention of

         offer to sell the Series A Notes only to, and will solicit offers to
         buy the Series A Notes only from (A) Eligible Purchasers that the
         Initial Purchaser reasonably believes are QIBs, and (B) Regulation S

         Series A Notes or the Series A Guarantees;

         (f) The Series A Notes offered and sold by such Initial Purchaser
         pursuant hereto in reliance on Regulation S have been and will be
         offered and sold only in offshore transactions;

         (g) The sale of the Series A Notes offered and sold by such Initial

         (h) Such Initial Purchaser agrees that it has not offered or sold and
         will not offer or sell the Series A Notes in the United States or to,
         or for the benefit or account of, a U.S. Person (other than a
         distributor), in each case, as defined in Rule 902 under the Act (i) as
         part of its distribution at any time and (ii) otherwise until 40 days
         after the later of the commencement of the offering of the Series A
         Notes pursuant hereto and the Closing Date, other than in accordance
         with Regulation S of the Act or another exemption from the registration
         requirements of the Act. Such Initial Purchaser agrees that, during
         such 40-day restricted period, it will not cause any advertisement with
         respect to the Series A


                                       22

         Notes (including any "tombstone" advertisement) to be published in any
         newspaper or periodical or posted in any public place and will not
         issue any Memorandum relating to the Series A Notes, except such
         advertisements as are permitted by and include the statements required
         by Regulation S;

         (i) Such Initial Purchaser agrees that, at or prior to confirmation of
         a sale of Series A Notes by it to any distributor, dealer or person
         receiving a selling concession, fee or other remuneration during the
         40-day restricted period referred to in Rule 903(b) under the Act, it
         will send to such distributor, dealer or person receiving a selling
         concession, fee or other remuneration a confirmation or notice to
         substantially the following effect:

                  "The Series A Notes covered hereby have not been registered
                  under the U.S. Securities Act of 1933, as amended (the
                  "Securities Act"), and may not be offered and sold within the
                  United States or to, or for the account or benefit of, U.S.
                  persons (i) as part of your distribution at any time or (ii)
                  otherwise until 40 days after the later of the commencement of
                  the Offering and the Closing Date, except in either case in
                  accordance with Regulation S under the Securities Act (or Rule
                  144A or to institutional accredited investors as defined in
                  Rule 501(a)(1), (2), (3) or (7) under the Securities Act, in
                  transactions that are exempt from the registration
                  requirements of the Securities Act), and in connection with
                  any subsequent sale by you of the Series A Notes covered
                  hereby in reliance on Regulation S during the period referred
                  to above to any distributor, dealer or person receiving a
                  selling concession, fee or other remuneration, you must
                  deliver a notice to substantially the foregoing effect.
                  Terms used above have the meanings assigned to them in
                  Regulation S."; and

         (j) Such initial purchaser:

                  (i) has not offered or sold and, prior to the date six months
                  after the date of issuance of the Series A Notes, will not
                  offer or sell any notes to persons in the United Kingdom
                  except to persons whose ordinary activities involve them in
                  acquiring, holding, managing or disposing of investments (as
                  principal or agent) for the purposes of their businesses or
                  otherwise in circumstances which have not resulted and will
                  not result in an offer to the public in the United Kingdom
                  within the meaning of the Public Offers of Securities
                  Regulations 1995 (as amended);

                  (ii) has only communicated or caused to be communicated and
                  will only communicate or cause to be communicated any
                  invitation or inducement to engage in investment activity
                  (within the meaning of Section 21 of the Financial Services
                  and Markets Act 2000 received by it in connection with the
                  issue or sale of any Series A Notes in circumstances in which
                  Section 21(1) of the Financial Services and Markets Act 2000
                  does not apply to us or the guarantors; and

                  (iii) has complied and will comply with all applicable
                  provisions of the Financial Services and Markets Act 2000 with
                  respect to anything done by it in relation to the Series A
                  Notes in, from or otherwise involving the United Kingdom.


                                       23









         Each Initial Purchaser acknowledges that the Issuers and the Subsidiary
Guarantors and, for purposes of the opinions to be delivered to each Initial
Purchaser pursuant to Section 9 hereof, counsel to the Issuers and the
Subsidiary Guarantors and counsel to the Initial Purchasers will rely upon the
accuracy and truth of the foregoing representations and the Initial Purchasers
hereby consent to such reliance.

8.       Indemnification.

         (a) Each of the Issuers and each Subsidiary Guarantor agree, jointly
         and severally, to indemnify and hold harmless the Initial Purchasers,
         their directors, affiliates, their officers and each person, if any,
         who controls such Initial Purchasers within the meaning of Section 15
         of the Act or Section 20 of the Exchange Act, from and against any and
         all losses, claims, damages, liabilities and judgments (including,
         without limitation, any legal or other expenses incurred in connection
         with investigating or defending any matter, including any action, that
         could give rise to any such losses, claims, damages, liabilities or
         judgments) caused by any untrue statement or alleged untrue statement
         of a material fact contained in the Offering Memorandum (or any
         amendment or supplement thereto) or any information provided by the
         Issuers or any Subsidiary Guarantor to any holder or prospective
         purchaser of Series A Notes pursuant to Section 5(f), or caused by any
         omission or alleged omission to state therein a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading, except insofar as such losses, claims, damages, liabilities
         or judgments are caused by any such untrue statement or omission or
         alleged untrue statement or omission based upon information relating to
         the Initial Purchasers furnished in writing to the Issuers by such
         Initial Purchaser (and not with respect to the information provided by
         any other Initial Purchaser).

         (b) The Initial Purchasers agree, severally and not jointly, to
         indemnify and hold harmless the Issuers and the Subsidiary Guarantors,
         and their respective directors and officers and each person, if any,
         who controls (within the meaning of Section 15 of the Act or Section 20
         of the Exchange Act) the Issuers or the Subsidiary Guarantors, to the
         same extent as the foregoing indemnity from the Issuers and the
         Subsidiary Guarantors to the Initial Purchasers but only with reference
         to information relating to the Initial Purchaser furnished in writing
         to the Issuers by such Initial Purchaser expressly for use in the
         Offering Memorandum and not with respect to the information provided by
         any other Initial Purchaser.

         (c) In case any action shall be commenced involving any person in
         respect of which indemnity may be sought pursuant to Section 8(a) or
         8(b) (the "indemnified party"), the indemnified party shall promptly
         notify the person against whom such indemnity may be sought (the
         "indemnifying party") in writing and the indemnifying party shall
         assume the defense of such action, including the employment of counsel
         reasonably satisfactory to the indemnified party and the payment of all
         fees and expenses of such counsel, as incurred (except that in the case
         of any action in respect of which indemnity may be sought pursuant to
         both Sections 8(a) and 8(b), the Initial Purchasers shall not be
         required to assume the defense of such action pursuant to this Section
         8(c), but may employ separate counsel and participate in the defense
         thereof, but the fees and expenses of such counsel, except as provided
         below, shall be at the expense of the Initial Purchasers). Any


                                       24

         indemnified party shall have the right to employ separate counsel in
         any such action and participate in the defense thereof, but the fees
         and expenses of such counsel shall be at the expense of the indemnified
         party unless (i) the employment of such counsel shall have been
         specifically authorized in writing by the indemnifying party, (ii) the
         indemnifying party shall have failed to assume the defense of such
         action or employ counsel reasonably satisfactory to the indemnified
         party or (iii) the named parties to any such action (including any
         impleaded parties) include both the indemnified party and the
         indemnifying party, and the indemnified party shall have been advised
         by such counsel that there may be one or more legal defenses available
         to it which are different from or additional to those available to the
         indemnifying party (in which case the indemnifying party shall not have
         the right to assume the defense of such action on behalf of the
         indemnified party). In any such case, the indemnifying party shall not,
         in connection with any one action or separate but substantially similar
         or related actions in the same jurisdiction arising out of the same
         general allegations or circumstances, be liable for the fees and
         expenses of more than one separate firm of attorneys (in addition to
         any local counsel) for all indemnified parties and all such fees and
         expenses shall be reimbursed as they are incurred. Such firm shall be
         designated in writing by J.P. Morgan Securities Inc., in the case of
         the parties indemnified pursuant to Section 8(a), and by the Issuers,
         in the case of parties indemnified pursuant to Section 8(b). The
         indemnifying party shall indemnify and hold harmless the indemnified
         party from and against any and all losses, claims, damages, liabilities
         and judgments by reason of any settlement of any action (i) effected
         with its written consent or (ii) effected without its written consent
         if the settlement is entered into more than twenty business days after
         the indemnifying party shall have received a request from the
         indemnified party for reimbursement for the fees and expenses of
         counsel (in any case where such fees and expenses are at the expense of
         the indemnifying party) and, prior to the date of such settlement, the
         indemnifying party shall have failed to comply with such reimbursement
         request. No indemnifying party shall, without the prior written consent
         of the indemnified party, effect any settlement or compromise of, or
         consent to the entry of judgment with respect to, any pending or
         threatened action in respect of which the indemnified party is or could
         have been a party and indemnity or contribution may be or could have
         been sought hereunder by the indemnified party, unless such settlement,
         compromise or judgment (i) includes an unconditional release of the
         indemnified party from all liability on claims that are or could have
         been 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 the indemnified party.

         (d) To the extent the indemnification provided for in this Section 8 is
         unavailable to an indemnified party or insufficient in respect of any
         losses, claims, damages, liabilities or judgments referred to therein,
         then each indemnifying party, in lieu of indemnifying such indemnified
         party, shall contribute to the amount paid or payable by such
         indemnified party as a result of such losses, claims, damages,
         liabilities and judgments (i) in such proportion as is appropriate to
         reflect the relative benefits received by the Issuers and the
         Subsidiary Guarantors, on the one hand, and the Initial Purchasers on
         the other hand from the offering of the Series A Notes or (ii) if the
         allocation provided by clause 8(d)(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 8(d)(i) above but also
         the relative fault of the


                                       25

         Issuers and the Subsidiary Guarantors, on the one hand, and the Initial
         Purchasers, on the other hand, in connection with the statements or
         omissions which resulted in such losses, claims, damages, liabilities
         or judgments, as well as any other relevant equitable considerations.
         The relative benefits received by the Issuers and the Subsidiary
         Guarantors, on the one hand and the Initial Purchasers, on the other
         hand, shall be deemed to be in the same proportion as the total net
         proceeds from the offering of the Series A Notes (after discounts and
         commissions received by the Initial Purchasers, but before deducting
         expenses) received by the Issuers, and the total discounts and
         commissions received by the Initial Purchasers bear to the total price
         to investors of the Series A Notes, in each case as set forth in the
         table on the cover page of the Offering Memorandum. The relative fault
         of the Issuers and the Subsidiary Guarantors, on the one hand, and the
         Initial Purchasers, on the other hand, 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 Issuers or the
         Subsidiary Guarantors, on the one hand, or the Initial Purchasers, on
         the other hand, and the parties' relative intent, knowledge, access to
         information and opportunity to correct or prevent such statement or
         omission.

         The Issuers and the Subsidiary Guarantors, and the Initial Purchasers
         agree that it would not be just and equitable if contribution pursuant
         to this Section 8(d) were determined by pro rata allocation, even if
         the Initial Purchasers were treated as one entity for such purpose, or
         by any other method of allocation which does not take account of the
         equitable considerations referred to in the immediately preceding
         paragraph. The amount paid or payable by an indemnified party as a
         result of the losses, claims, damages, liabilities or judgments
         referred to in the immediately preceding paragraph shall be deemed to
         include, subject to the limitations set forth above, any legal or other
         expenses incurred by such indemnified party in connection with
         investigating or defending any matter, including any action, that could
         have given rise to such losses, claims, damages, liabilities or
         judgments. Notwithstanding the provisions of this Section 8, the
         Initial Purchasers shall not be required to contribute any amount in
         excess of the amount by which the total discounts and commissions
         received by such Initial Purchasers exceeds the amount of any damages
         which each Initial Purchaser 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 Initial Purchasers' obligations to contribute
         pursuant to this Section 8(d) are several in proportion to the
         respective principal amount of Series A Notes purchased by each of the
         Initial Purchasers hereunder and not joint.

         (e) The remedies provided for in this Section 8 are not exclusive and
         shall not limit any rights or remedies which may otherwise be available
         to any indemnified party at law or in equity.

9.       Conditions of Initial Purchasers' Obligations. The obligations of each
         of the Initial Purchasers to purchase the Series A Notes under this
         Agreement are subject to the satisfaction of each of the following
         conditions:


                                       26

         (a) All the representations and warranties of the Issuers and the
         Subsidiary Guarantors contained in this Agreement shall be true and
         correct in all material respects on the Closing Date with the same
         force and effect as if made on and as of the Closing Date, provided
         that the representations and warranties qualified by "materiality"
         shall be true and correct on the Closing Date;

         (b) On or after the date hereof, there shall not have occurred (i) any
         downgrading, suspension or withdrawal of, nor shall any notice have
         been given of any potential or intended downgrading, suspension or
         withdrawal of, or of any review (or of any potential or intended
         review) for a possible change that either does not indicate the
         direction of the possible change or indicates a negative change in, any
         rating of the Issuers or any Subsidiary Guarantor or any securities of
         the Issuers or any Subsidiary Guarantor (including, without limitation,
         the placing of any of the foregoing ratings on credit watch with
         negative or developing implications or under review with an uncertain
         or negative direction) by any "nationally recognized statistical rating
         organization" as such term is defined for purposes of Rule 436(g)(2)
         under the Act, (ii) any change, nor shall any notice have been given of
         any potential or intended change, in the outlook for any rating of the
         Issuers or any Subsidiary Guarantor or any securities of the Issuers or
         any Subsidiary Guarantor by any such rating organization and (iii) no
         such rating organization shall have given notice that it has assigned
         (or is considering assigning) a lower rating to the Notes than that on
         which the Notes were marketed; (iv) 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 J.P. Morgan
         Securities Inc., be likely to prejudice materially the success of the
         proposed issue, sale or distribution of the Notes, whether in the
         primary market or in respect of dealings in the secondary market; (v)
         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 Issuers on any exchange or in the
         over-the-counter market; (vi) any banking moratorium declared by U.S.
         Federal or New York authorities; (vii) any major disruption of
         settlements of securities or clearance services in the United States or
         (viii) 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 J.P. Morgan Securities Inc., the effect of any
         such attack, outbreak, escalation, act, declaration, calamity or
         emergency makes it impractical or inadvisable to proceed with
         completion of the offering or sale of and payment for the Series A
         Notes on the terms and in the manner contemplated in the Offering
         Memorandum.

         (c) Since the respective dates as of which information is given in the
         Offering Memorandum other than as set forth in the Offering Memorandum
         (exclusive of any amendments or supplements thereto subsequent to the
         date of this Agreement), (i) there shall not have occurred any change
         or any development involving a prospective change in the condition,
         financial or otherwise, or the earnings, business, management or
         operations of the Partnership and its subsidiaries and GulfTerra
         Finance, taken as a whole, (ii) there shall not have been any change or
         any development involving a prospective change in the capital stock,
         limited liability company interests or partnership units, as
         applicable, or in the long-term debt of the Issuers or any of their
         subsidiaries and

         (iii) neither the Issuers nor any of their subsidiaries shall have
         incurred any liability or obligation, direct or contingent, the effect
         of which, in any such case described in clause 9(c)(i), 9(c)(ii) or
         9(c)(iii), in your judgment, is material and adverse and, in your
         judgment, makes it or impracticable or inadvisable to proceed with the
         completion of the offering and sale and payment for market the Series A
         Notes on the terms and in the manner contemplated in the Offering
         Memorandum;

                  other than the rights of the General Partner and its
                  affiliates in Section 6.14 of the Partnership Agreement and in
                  the Series C RRA (which rights have been waived in connection
                  with any Registration Statement filed pursuant to the
                  Registration Rights Agreement).

                  (xvii) The Indenture complies as to form in all material
                  respects with the requirements of the TIA, and the rules and
                  regulations of the Commission applicable to an indenture which
                  is qualified thereunder. It is not necessary in connection
                  with the offer, sale and delivery of the Series A Notes to the
                  Initial Purchasers in the manner contemplated by this
                  Agreement or in connection with the initial placement of the
                  Series A Notes by the Initial Purchasers in the manner
                  contemplated by the Offering Memorandum pursuant to Exempt
                  Resales to qualify the Indenture under the TIA (it being
                  understood that such counsel need express no opinion as to any
                  other offer or sale);

                  (xviii) No registration under the Act of the Series A Notes is
                  required for the sale of the Series A Notes to the Initial
                  Purchasers as contemplated by this Agreement or for the Exempt
                  Resales assuming that (i) each Initial Purchaser is a QIB, or
                  a


                                       31

                  Regulation S Purchaser, (ii) the accuracy of, and compliance
                  with, the Initial Purchasers' representations and agreements
                  contained in Section 7 of this Agreement and (iii) the
                  accuracy of the representations and agreements of each of the
                  Issuers and the Subsidiary Guarantors set forth in Sections
                  5(f) and (k) and 6(dd), (gg), (hh), (jj), (kk), (ll) and (mm)
                  of this Agreement;

                  (xix) The Offering Memorandum, as of its date, and each
                  amendment or supplement thereto, as of its date, complied as
                  to form in all material respects with the applicable
                  requirements of Rule 144A(d)(4) of the Act (it being
                  understood that such counsel need express no opinion with
                  respect to this paragraph (xix) regarding the financial
                  statements and the notes thereto, oil and gas reserve
                  information and the schedules and other financial data
                  included in the Offering Memorandum);

                  (xx) A court applying Texas conflict of laws rules in a
                  properly presented and argued case should give effect to the
                  express choice of law provisions contained in the Operative
                  Documents to the extent that such provisions provide that the
                  laws of the State of New York are to govern issues under the
                  Operative Documents.

         In addition, such counsel shall include a statement in such opinion
         letter to the effect that although such counsel has not undertaken,
         except as otherwise indicated in their opinion, to determine
         independently, and does not assume any responsibility for, the accuracy
         or completeness of the statements in the Offering Memorandum, such
         counsel has participated in the preparation of the Offering Memorandum
         and any amendments or supplements thereto, including review and
         discussion of the contents thereof, and nothing has come to the
         attention of such counsel that has caused them to believe that, as of
         the date of the Offering Memorandum or as of the Closing Date, the
         Offering Memorandum, as amended or supplemented, if applicable,
         contained or contains any untrue statement of a material fact or
         omitted or omits to state a material fact necessary in order to make
         the statements therein, in the light of the circumstances under which
         they were made, not misleading (it being understood that such counsel
         need express no opinion with respect to the financial statements and
         notes thereto, oil and gas reserve information and the schedules and
         other financial data included in the Offering Memorandum).

         The opinion of Akin, Gump, Strauss, Hauer & Feld, L.L.P. described in
         Section 9(e) above (i) may be subject to customary qualifications,
         assumptions and limitations and (ii) shall be rendered to you at the
         request of the Issuers and the Subsidiary Guarantors and shall so state
         therein.

         (f) The Initial Purchasers shall have received on the Closing Date an
         opinion, dated the Closing Date, of Gregory W. Jones, counsel for the
         Partnership, to the effect that:

                  (i) except as set forth in the Offering Memorandum, such
                  counsel does not know of any legal or governmental proceedings
                  pending or threatened to which the Partnership or any of its
                  Restricted Subsidiaries or GulfTerra Finance is a party or to
                  which any of their respective property is subject, except for
                  those


                                       32

                  which, singly or in the aggregate, could reasonably be
                  expected not to result in a Material Adverse Effect;

                  (ii) The execution, delivery and performance of this Agreement
                  and the other Operative Documents by each of the Issuers and
                  each of the Subsidiary Guarantors, the compliance by each of
                  the Issuers and each of the Subsidiary Guarantors with all
                  provisions hereof and thereof and the consummation by the
                  Issuers and the Subsidiary Guarantors, of the transactions
                  contemplated by this Agreement and the other Operative
                  Documents will not, to the knowledge of such counsel, (A)
                  violate or conflict with any applicable law or any rule,
                  regulation, judgment, order or decree of any court or any
                  governmental body or agency having jurisdiction over the
                  Partnership, any of its Restricted Subsidiaries or GulfTerra
                  Finance or their respective property or (B) result in the
                  termination, suspension or revocation of any Authorization of
                  the Partnership or any of its Restricted Subsidiaries or
                  GulfTerra Finance or result in any other impairment of the
                  rights of the holder of any such Authorization, except for
                  those which, singly or in the aggregate, could reasonably be
                  expected not to result in a Material Adverse Effect; and
                  except that such counsel need express no opinion regarding
                  antifraud provisions of federal or state securities or blue
                  sky laws with respect to clause (A) of this paragraph (B);

                  (iii) To the knowledge of such counsel, (A) each of the
                  Partnership and its Restricted Subsidiaries and GulfTerra
                  Finance has such Authorizations of, and has made all filings
                  with and notices to, all governmental or regulatory
                  authorities and self-regulatory organizations and all courts
                  and other tribunals, including without limitation, under any
                  applicable Environmental Laws, as are necessary to own, lease,
                  license and operate its respective properties and to conduct
                  its business, except where the failure to have any such
                  Authorization or to make any such filing or notice could,
                  singly or in the aggregate, reasonably be expected not to have
                  a Material Adverse Effect; (B) each such Authorization known
                  to us is valid and in full force and effect and, to the
                  knowledge of such counsel, each of the Partnership and its
                  Restricted Subsidiaries and GulfTerra Finance is in compliance
                  with all the terms and conditions thereof and with the rules
                  and regulations of the authorities and governing bodies having
                  jurisdiction with respect thereto; (C) no event has occurred
                  (including the receipt of any notice from any authority or
                  governing body) which allows or, after notice or lapse of time
                  or both, would allow, revocation, suspension or termination of
                  any such Authorization or results or, after notice or lapse of
                  time or both, would result in any other material impairment of
                  the rights of the holder of any such Authorization; and (D)
                  such Authorizations contain no restrictions that are
                  materially burdensome to the Partnership or any of its
                  Restricted Subsidiaries or GulfTerra Finance; except in the
                  case of (A) through (D) above those which could reasonably be
                  expected not to, singly or in the aggregate, have a Material
                  Adverse Effect; and

                  (iv) Neither the General Partner nor the Partnership is a
                  "holding company" or, after giving effect to the offering and
                  sale of the Series A Notes and the


                                       33

                  application of the proceeds thereof as described in the
                  Offering Memorandum will be a "holding company," within the
                  meaning of, or subject to regulation under, the Public Holding
                  Utility Company Act of 1935, as amended, and the rules and
                  regulations promulgated by the Commission thereunder.

         (g) The Initial Purchasers shall have received on the Closing Date an
         opinion, dated the Closing Date, of Simpson Thacher & Bartlett LLP,
         counsel for the Initial Purchasers, in form and substance reasonably
         satisfactory to the Initial Purchasers.

         (h) The Initial Purchasers shall have received, at the time this
         Agreement is executed and at the Closing Date, letters dated the date
         hereof or the Closing Date, as the case may be, in form and substance
         satisfactory to the Initial Purchasers containing the information and
         statements of the type ordinarily included in accountants' "comfort
         letters" to the Initial Purchasers from PricewaterhouseCoopers LLP,
         independent public accountants, with respect to the financial
         statements of the Issuers and their subsidiaries, and certain financial
         information contained in the Offering Memorandum.

         (i) The Initial Purchasers shall have received, at the time of this
         Agreement is executed and at the Closing Date, letters dated the date
         hereof or the Closing Date, as the case may be, in form and substance
         satisfactory to the Initial Purchasers from Netherland & Sewell.

         (j) The Series A Notes shall have been approved by the NASD for trading

         (m) Neither the Issuers nor the Subsidiary Guarantors shall have failed
         at or prior to the Closing Date to perform or comply with any of the
         agreements herein contained and required to be performed or complied
         with by each of the Issuers or the Subsidiary Guarantors, as the case
         may be, at or prior to the Closing Date.

10.      Effectiveness of Agreement and Termination. This Agreement shall become
         effective upon the execution and delivery of this Agreement by the
         parties hereto.

         This Agreement may be terminated at any time on or prior to the Closing
Date by the Initial Purchasers by written notice to the Issuers if any of the
following has occurred: (i) any outbreak or escalation of hostilities or other
national or international calamity or crisis or change in economic conditions or
in the financial markets of the United States or elsewhere that, in any of the
Initial Purchasers' judgment, is material and adverse and, in any of the Initial
Purchasers' judgment, makes it impracticable or inadvisable to proceed with the
completion of the offering and sale and payment for the Series A Notes on the
terms and in the manner contemplated in the Offering Memorandum, (ii) the
suspension or material limitation of trading in securities or other instruments
on the New York Stock Exchange, the American Stock Exchange, the Chicago


                                       34

Board of Options Exchange, the Chicago Mercantile Exchange, the Chicago Board of

suspension of trading of any securities of the Issuers or any Subsidiary
Guarantor on any exchange or in the over-the-counter market, (iv) the enactment,
publication, decree or other promulgation of any federal or state statute,
regulation, rule or order of any court or other governmental authority which in
your opinion materially and adversely affects, or will materially and adversely
affect, the business, prospects, financial condition or results of operations of
the Issuers and their subsidiaries, taken as a whole, (v) the declaration of a
banking moratorium by either federal or New York State authorities or (vi) the
taking of any action by any federal, state or local government or agency in
respect of its monetary or fiscal affairs which in your opinion has a material
adverse effect on the financial markets in the United States.

         If on the Closing Date any one or more of the Initial Purchasers shall
fail or refuse to purchase the Series A Notes which it or they have agreed to
purchase hereunder on such date and the aggregate principal amount of the Series
A Notes which such defaulting Initial Purchaser or Initial Purchasers, as the
case may be, agreed but failed or refused to purchase is not more than one-tenth
of the aggregate principal amount of the Series A Notes to be purchased on such
date by all Initial Purchasers, each non-defaulting Initial Purchaser shall be
obligated severally, in the proportion which the principal amount of the Series
A Notes set forth opposite its name in Schedule B bears to the aggregate
principal amount of the Series A Notes which all the non-defaulting Initial
Purchasers, as the case may be, have agreed to purchase, or in such other
proportion as you may specify, to purchase the Series A Notes which such
defaulting Initial Purchaser or Initial Purchasers, as the case may be, agreed
but failed or refused to purchase on such date; provided that in no event shall
the aggregate principal amount of the Series A Notes which any Initial Purchaser
has agreed to purchase pursuant to Section 2 hereof be increased pursuant to
this Section 10 by an amount in excess of one-ninth of such principal amount of
the Series A Notes without the consent of such Initial Purchaser. If on the
Closing Date any Initial Purchaser or Initial Purchasers shall fail or refuse to
purchase the Series A Notes and the aggregate principal amount of the Series A
Notes with respect to which such default occurs is more than one-tenth of the
aggregate principal amount of the Series A Notes to be purchased by all Initial
Purchasers and arrangements satisfactory to the Initial Purchasers and the
Issuers for purchase of such Series A Notes are not made within 48 hours after
such default, this Agreement will terminate without liability on the part of any
non-defaulting Initial Purchaser and the Issuers. In any such case which does
not result in termination of this Agreement, either you or the Issuers shall
have the right to postpone the Closing Date, but in no event for longer than
seven days, in order that the required changes, if any, in the Offering
Memorandum or any other documents or arrangements may be effected. Any action
taken under this paragraph shall not relieve any defaulting Initial Purchaser
from liability in respect of any default of any such Initial Purchaser under
this Agreement.

         This Agreement may be terminated at any time on or prior to the Closing
Date by the Issuers by written notice to the Initial Purchasers if, there is a
failure to obtain any consent or waiver under, or amendment of, the Credit
Facility, that is required in order for the issuance of the Notes to not
constitute a default thereunder.

         representations, warranties and other statements of the Issuers, the
         Subsidiary Guarantors and the Initial Purchasers, set forth in or made
         pursuant to this Agreement shall remain operative and in full force and
         effect, and will survive delivery of and payment for the Series A
         Notes, regardless of (i) any investigation, or statement as to the
         results thereof, made by or on behalf of the Initial Purchasers, the
         officers or directors of the Initial Purchasers, any person controlling
         the Initial Purchasers, the Issuers, any Subsidiary Guarantor, the
