("Delos") has been duly authorized, executed and delivered by EFS and Delos and constitutes a valid and binding obligation of EFS and Delos enforceable against EFS and Delos in accordance with its terms, subject to Enforceability Exceptions; The Chaco Documents have each been duly authorized, executed and delivered by the Partnership Subsidiaries party thereto; (xv) to the knowledge of such counsel, no holders of securities of the Partnership have rights to the registration of Common Units under the Registration Statement except for the rights (i) of the General Partner and its affiliates and successors in Section 6.14 of the Partnership Agreement, (ii) of EPEC and its successors pursuant to the Registration Rights Agreement between EPEC and the Partnership which was executed in connection with the acquisition by the Partnership of an additional interest in Viosca Knoll Gathering Company and (iii) of Crystal pursuant to the Registration Rights Agreement between Crystal and the Partnership which was executed in connection with the acquisition by the Partnership of the Crystal storage facilities; and (xvi) to the knowledge of such counsel: (a) there is no franchise, contract or other document of a character required to be described in the Registration Statement or Prospectus, or to be filed as an exhibit thereto, which is not described or filed as required; and (b) the statements included or incorporated by reference in the Prospectus under the headings "Description of Limited Partner Interests", "Certain Other Partnership Agreement Provisions", and "Income Tax Considerations", insofar as such statements summarize legal matters, agreements, documents or proceedings discussed therein, are 25

accurate and fair summaries of such legal matters, agreements, documents or proceedings. Such counsel shall also state 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 Registration Statement and the Prospectus, such counsel has participated in the preparation of the Registration Statement and the Prospectus, including review and discussion of the contents thereof, and nothing has come to the attention of such counsel that has caused them to believe: (i) that the Registration Statement, on the effective date or the date hereof, 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, (ii) that the Prospectus, as of its date or as of the Time of Delivery, contained any 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, or (iii) that any amendment or supplement to the Prospectus, as of its respective date, and as of the Time of Delivery, contained any untrue statement of a material fact or omitted 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, the notes and the schedules thereto oil and gas reserve information and other financial data included in the Registration Statement or the Prospectus). Such counsel shall also state that, with respect to (i) and (ii) in paragraph (xv above, (a) the General Partner, Sabine I and Sabine II have agreed not to exercise their registration rights with respect to such securities in connection with the offering of Units for 90 days hereafter pursuant to letter agreements of even date herewith, and (b) the Common Units held by the General Partner, Sabine I and Sabine II are subject to Permitted Encumbrances, the holders of which have not waived such rights. In rendering such opinion, such counsel may (A) rely as to matters involving the application of laws of any jurisdiction other than the State of Delaware or the Federal laws of the United States, to the extent they deem proper and specified in such opinion, upon the opinion of other counsel of good standing whom they believe to be reliable and who are satisfactory to counsel for the Underwriters, of which a copy of any such opinion shall be delivered to the Underwriters, (B) rely as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Partnership and public officials, (C) assume that the signatures on all documents examined by such counsel are genuine, which assumptions they may state they have not independently verified, (D) state that their opinion is limited to federal laws, the Delaware Act, the Delaware General Corporation Law, the Delaware Limited Liability Company Act, New York law and Texas law, (E) state that they express no opinion with respect to state or local taxes or tax statutes to which any of the Partnership, the 26

limited partners of the Partnership or the General Partner may be subject and (F) state that their opinion is furnished as counsel for the Partnership and the General Partner to you, as Representatives of the several Underwriters, and is solely for the benefit of the several Underwriters. References to the Registration Statement and the Prospectus in this paragraph (b) include any amendments and supplements thereto at the Time of Delivery. (d) David Zerhusen, Esq., counsel for the Partnership, or such other counsel for the Partnership reasonably satisfactory to the Representatives, shall have furnished to you his written opinion, dated such Time of Delivery, in form and substance satisfactory to you, to the effect that: (i) to the knowledge of such counsel there is no pending or threatened action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Partnership or any of its Subsidiaries or the General Partner or its or their property of a character required to be disclosed in the Prospectus which is not adequately disclosed in the Prospectus, except those that (a) would not be likely to have, in the reasonable judgment of such counsel, a material adverse effect on the performance of this Agreement or the consummation of any of the transactions contemplated hereby or (b) would not be likely to have, in the reasonable judgment of such counsel, a material adverse effect on the condition (financial or otherwise), earnings, business or properties of the Partnership and its Subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Prospectus (exclusive of any supplement thereto); and (ii) each of the Partnership and the General Partner is not and after giving effect to the offering and sale of the Units and the application of the proceeds thereof as described in the Prospectus, will not be a "holding company" within the meaning of, or subject to regulation under, the Public Utility Holding Company Act of 1935, as amended, and the rules and regulations promulgated by the Commission thereunder. (e) The Partnership shall have requested and caused PricewaterhouseCoopers LLP, at the time this Agreement is executed and at such Time of Delivery, and shall have requested Arthur Andersen LLP at such Time of Delivery, to have furnished to the Underwriters letters, dated as of the time of this Agreement and as of such Time of Delivery, as the case may be, in form and substance satisfactory to the Underwriters, confirming that they are independent accountants within the meaning of the Act and the Exchange Act and the respective applicable rules and regulations adopted by the Commission thereunder with respect to the Partnership, Partnership Subsidiary or Partnership joint venture whose financial statements they have respectively audited and containing the information and 27

statements of the type ordinarily included in accountants' "comfort letters" to the Underwriters with respect to the financial statements and certain financial information contained in the Registration Statement and the Prospectus; (f) The Partnership shall have requested and caused Netherland, Sewell & Associates, Inc., at the time this Agreement is executed and at such Time of Delivery, to have furnished to the Underwriters letters, dated as of the time of this Agreement and as of such time of Delivery, as the case may be, in form and substance satisfactory to the Underwriters, confirming that they are independent petroleum engineers with respect to evaluating the oil and gas reserves of the Partnership and its Subsidiaries as of December 31, 2000 contained in the Registration Statement and the Prospectus; (g) (i) None of the General Partner, the Partnership nor any of its Subsidiaries shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Prospectus any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Prospectus, and (ii) since the respective dates as of which information is given in the Prospectus there shall not have been any change in the capitalization or short-term or long-term debt of the General Partner, the Partnership or any of its Subsidiaries or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, partners' equity or results of operations of the General Partner, the Partnership and its Subsidiaries, taken as a whole, otherwise than as set forth or contemplated in the Prospectus, the effect of which, in any such case described in clause (i) or (ii), is in the judgment of the Underwriters so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Units being delivered at such Time of Delivery on the terms and in the manner contemplated in the Prospectus; (h) On or after the date hereof (i) no downgrading shall have occurred in the rating accorded the General Partner's or the Partnership's debt securities by any "nationally recognized statistical rating organization", as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the General Partner's or the Partnership's debt securities; (i) On or after the date hereof there shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the Exchange; (ii) a suspension or material limitation in trading in the Partnership's securities on the Exchange; (iii) a general moratorium on commercial banking activities declared by either Federal or New York or Texas State authorities or a material 28

disruption in commercial banking or securities settlement or clearance services in the United States; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war; or (v) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in the judgment of the Representatives makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Units being delivered at such Time of Delivery on the terms and in the manner contemplated in the Prospectus; (j) The Units to be sold at such Time of Delivery shall have been duly listed, subject to notice of issuance, on the Exchange; (k) The Partnership has obtained and delivered to the Underwriters executed copies of an agreement from the General Partner, Sabine I and Sabine II, substantially to the effect set forth in the form attached hereto as Annex C; (l) The Partnership shall have complied with the provisions of Section 5(c) hereof with respect to the furnishing of prospectuses on the New York Business Day next succeeding the date of this Agreement; and (m) The Partnership and the General Partner shall have furnished or caused to be furnished to you at such Time of Delivery certificates of officers of the Partnership and the General Partner satisfactory to you as to the accuracy of the representations and warranties of the Partnership and the General Partner herein at and as of such Time of Delivery, as to the performance by the Partnership and the General Partner of all of its obligations hereunder to be performed at or prior to such Time of Delivery, as to the matters set forth in subsections (a) and (g) of this Section and as to such other matters as you may reasonably request. 8. (a) Each of the Partnership and the General Partner, jointly and severally, will indemnify and hold harmless each Underwriter 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 an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus, or any amendment or supplement thereto, 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 action or claim as such expenses are incurred; provided, however, that the Partnership and the General Partner shall 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 or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement or the Prospectus or any such 29

amendment or supplement in reliance upon and in conformity with written information furnished to the Partnership by any Underwriter through Goldman, Sachs & Co. expressly for use therein; provided that with respect to any untrue statement or omission of material fact made in any Preliminary Prospectus, the indemnity agreement contained in this Section 8(a) shall not inure to the benefit of any Underwriter from whom the person asserting any such loss, claim, damage or liability purchased the Units concerned, to the extent that any such loss, claim, damage or liability of such Underwriter occurs under the circumstance where it shall have been determined by a court of competent jurisdiction by final and nonappealable judgment that (w) the Partnership had previously furnished copies of the Prospectus to the Underwriters, (x) delivery of the Prospectus was required by the Act to be made to such person, (y) the untrue statement or omission of a material fact contained in the Preliminary Prospectus was corrected in the Prospectus and (z) there was not sent or given to such person, at or prior to the written confirmation of the sale of such securities to such person, a copy of the Prospectus. (b) Each Underwriter will indemnify and hold harmless the Partnership and the General Partner against any losses, claims, damages or liabilities to which either the Partnership, the General Partner or both 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 an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus, or any amendment or supplement thereto, 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, 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 any Preliminary Prospectus, the Registration Statement or the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Partnership by such Underwriter through Goldman, Sachs & Co. expressly for use therein; and will reimburse the Partnership and the General Partner for any legal or other expenses reasonably incurred by the Partnership and the General Partner in connection with investigating or defending any such action or claim as such expenses are incurred. (c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel 30

satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim 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 any indemnified party. (d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Partnership and the General Partner on the one hand and the Underwriters on the other from the offering of the Units. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Partnership and the General Partner 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 (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Partnership and the General Partner 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 Partnership bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. 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 Partnership and the General Partnership on the one hand or the Underwriters on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Partnership, the General Partner and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (d) were determined by pro rata allocation 31

(even if the Underwriters 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 above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in 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 such action or claim. 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 Units 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 Partnership and the General Partner under this Section 8 shall be in addition to any liability which the Partnership and the General Partner 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 8 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 officer and director of the General Partner and to each person, if any, who controls the Partnership or the General Partner within the meaning of the Act. 9. (a) If any Underwriter shall default in its obligation to purchase the Units which it has agreed to purchase hereunder at a Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such Units on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Units, then the Partnership shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Units on such terms. In the event that, within the respective prescribed periods, you notify the Partnership that you have so arranged for the purchase of such Units, or the Partnership notifies you that it has so arranged for the purchase of such Units, you or the Partnership shall have the right to postpone such Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Partnership agrees to file promptly any amendments to the Registration Statement or the Prospectus which in your opinion may thereby be made necessary. The term "Underwriter" as used in this Agreement shall include any person substituted under this 32

Section with like effect as if such person had originally been a party to this Agreement with respect to such Units. (b) If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters by you and the Partnership as provided in subsection (a) above, the aggregate number of such Units which remains unpurchased does not exceed one-eleventh of the aggregate number of all the Units to be purchased at such Time of Delivery, then the Partnership shall have the right to require each non-defaulting Underwriter to purchase the number of Common Units which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Units which such Underwriter agreed to purchase hereunder) of the Units of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default. (c) If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters by you and the Partnership as provided in subsection (a) above, the aggregate number of such Units which remains unpurchased exceeds one-eleventh of the aggregate number of all the Units to be purchased at such Time of Delivery, or if the Partnership shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Units of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Second Time of Delivery, the obligations of the Underwriters to purchase and of the Partnership to sell the Optional Units) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter, the Partnership or the General Partner, except for the expenses to be borne by the Partnership, the General Partner and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default. 10. The respective indemnities, agreements, representations, warranties and other statements of the Partnership, the General Partner and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Partnership or the General Partner, or any officer or director or controlling person of the Partnership or the General Partner, and shall survive delivery of and payment for the Units. 11. If this Agreement shall be terminated pursuant to Section 9 hereof, neither the Partnership nor the General Partner shall then be under any liability to any Underwriter except as provided in Sections 6 and 8 hereof; but, if for any other reason, the Units are not delivered by or on behalf of the Partnership as provided herein, the Partnership and the 33

General Partner will reimburse the Underwriters through you for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Units not so delivered, but the Partnership and the General Partner shall then be under no further liability to any Underwriter except as provided in Sections 6 and 8 hereof. 12. In all dealings hereunder, you shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by you jointly or by Goldman, Sachs & Co. on behalf of you as the representatives. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to you as the representatives in care of Goldman, Sachs & Co., 85th Broad Street, 9th Floor, New York, New York 10004, Attention: Registration Department; and if to the Partnership shall be delivered or sent by mail to the address of the Partnership set forth in the Registration Statement, Attention: Secretary; provided, however, that any notice to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters' Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Partnership by you upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof. 13. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Partnership, the General Partner and, to the extent provided in Sections 8 and 10 hereof, the officers and directors of the General Partner and each person who controls the Partnership, the General Partner or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Units from any Underwriter shall be deemed a successor or assign by reason merely of such purchase. 14. TIME SHALL BE OF THE ESSENCE OF THIS AGREEMENT. 15. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. 16. This Agreement may be executed by any one or more of the parties hereto 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 instrument. 17. The Partnership is authorized, subject to applicable law, to disclose any and all aspects of this potential transaction that are necessary to support any U.S. federal income tax benefits expected to be claimed with respect to such transaction, without the Underwriters imposing any limitation of any kind. 34
