Ladies and Gentlemen:

Copano Energy, L.L.C., a Delaware limited liability company (the “Company”), and Copano Energy Finance Corporation, a Delaware corporation (“XxxXx”), propose to issue and sell to the several Underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”), $150,000,000 aggregate principal amount of their 7.125% Senior Notes due 2021 (the “Notes”). The Company and XxxXx are referred to collectively as the “Issuers.” The Notes will be issued pursuant to an Indenture dated as of April 5, 2011 (the “Base Indenture”) among the Company, XxxXx, the guarantors listed in Schedule 2 hereto (the “Guarantors”) and U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture, dated as of April 5, 2011 (the “First Supplemental Indenture”), and the Second Supplemental Indenture, dated as of April 6, 2011, (the “Second Supplemental Indenture” and the Base Indenture, as so supplemented by the First Supplemental Indenture and the Second Supplemental Indenture, the “Indenture”), and will be guaranteed on an unsecured senior basis by each of the Guarantors (the “Guarantees” and, together with the Notes, the “Securities”). The Notes constitute “Additional Notes” (as defined in Section 2.01 of the First Supplemental Indenture) under the First Supplemental Indenture. The Issuers have previously issued $360,000,000 aggregate principal amount of their 7.125% Senior Notes due 2021 (the “Existing Notes”) under the Indenture. Except as otherwise disclosed in the Time of Sale Information and the Prospectus, the Notes will have terms identical to the Existing Notes, and the Notes and the Existing Notes will be treated as a single series of debt securities for all purposes under the Indenture.

The Issuers and the Guarantors are referred to collectively as the “Copano Parties.” XxxXx and the Guarantors, together with Xxxx/Xxxxx Gatherers, a Texas general partnership (“Xxxx/Xxxxx”), Southern Dome, LLC, a Delaware limited liability company (“Southern Dome”), Bighorn Gas Gathering, L.L.C., a Delaware limited liability company (“Bighorn”), Fort Union Gas Gathering, L.L.C., a Delaware limited liability company (“Fort Union”), Liberty Pipeline Group, LLC (“Liberty Pipeline”), a Delaware limited liability company, and Eagle Ford Gathering LLC, a Delaware limited liability company (“Eagle Ford Gathering”) and Double Eagle Pipeline, LLC, a Delaware limited liability company (“Double Eagle”), are referred to collectively as the “Subsidiaries.”

The Copano Parties hereby confirm their agreement with the several Underwriters concerning the purchase and sale of the Notes, as follows:

1. Registration Statement. The Issuers have prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement on Form S-3 (File No. 333-162821), including a prospectus, relating to securities to be issued from time to time by the Issuers, including the Securities. Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means any prospectus filed with the Commission pursuant to Rule 424(b) under the Securities Act and the prospectus included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Notes. Any reference in this Agreement to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be, and any reference to “amend,” “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein.

At or prior to the time when sales of the Notes were first made (the “Time of Sale”), the following information shall have been prepared (collectively, the “Time of Sale Information”): a Preliminary Prospectus dated February 2, 2012, and each “free writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex D hereto as constituting part of the Time of Sale Information.

Additionally, neither the Representatives nor any other Underwriter is advising the Copano Parties or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Copano Parties shall consult with their own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and neither the Representatives nor any other Underwriters shall have any responsibility or liability to the Copano Parties with respect thereto. Any review by the Representatives or any Underwriters of the Copano Parties and the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Representatives or such Underwriter, as the case may be, and shall not be on behalf of the Copano Parties or any other person.

(b) Indemnification of the Copano Parties Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless each of the Copano Parties, each of their respective directors, each of their officers who signed the Registration Statement and each person, if any, who controls any of the Copano Parties within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages and liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Issuers in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, it being understood and agreed that the only such information consists of the following statements contained in the Preliminary Prospectus and the Prospectus: (i) the sentence regarding delivery of the Notes on the cover page and (ii) under the heading “Underwriting,” (A) the sentences related to concessions and (B) the paragraph related to stabilization.

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraphs (a) and (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraphs (a) and (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representatives and any such separate firm for the Copano Parties, their respective directors and officers who signed the Registration Statement and any control persons of the Copano Parties shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any

time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into (A) more than 60 days after receipt by the Indemnifying Person of such request and (B) more than 30 days after receipt by the Indemnifying Person of the terms of the proposed settlement and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Copano Parties on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Copano Parties on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Copano Parties on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Issuers from the sale of the Notes and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Notes. The relative fault of the Copano Parties on the one hand and the Underwriters on the other 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 Copano Parties or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Copano Parties and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the

equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

8. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Issuers, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange or NASDAQ; (ii) trading of the Company’s common units shall have been suspended on any exchange; (iii) a material disruption in securities settlement, payment or clearance services in the United States that reasonably could be expected to affect the settlement of the Securities shall have occurred; (iv) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (v) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Notes on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

9. Defaulting Underwriter.

(a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Notes that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Notes by other persons satisfactory to the Issuers on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Notes, then the Issuers shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Notes on such terms. If other persons become obligated or agree to purchase the Notes of a defaulting Underwriter, either the non-defaulting Underwriters or the Issuers may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Issuers or counsel for the Underwriters may be necessary in the Registration Statement and the

Prospectus or in any other document or arrangement, and the Issuers agree to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases Notes that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Issuers as provided in paragraph (a) above, the aggregate principal amount of such Notes that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Notes, then the Issuers shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Notes that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Notes that such Underwriter agreed to purchase hereunder) of the Notes of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Issuers as provided in paragraph (a) above, the aggregate principal amount of such Notes that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Notes, or if the Issuers shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Copano Parties, except that the Copano Parties will continue to be liable for the payment of expenses as set forth in Section 10 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Copano Parties or any non-defaulting Underwriter for damages caused by its default.

10.	Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Copano Parties jointly and severally agree to pay or cause to be paid all costs and expenses incident to the performance of their respective obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Notes and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing this Agreement and the Indenture;

(iv) the fees and expenses of counsel for the Copano Parties and independent accountants for the Company; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Underwriters); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, the Financial Industry Regulatory Authority; (ix) all expenses incurred by the Copano Parties in connection with any “road show” presentation to potential investors and (x) all other costs and expenses incident to the performance of the obligations of the Copano Parties hereunder for which provision is not otherwise made in this Section 10. It is understood, however, that except as provided in this Section 10 or in Section 7, the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel, transfer taxes payable on resale of any of the Notes by it and any advertising expenses connected with any offers it may make.

(b) If this Agreement is terminated by the Underwriters because any condition to the obligations of the Underwriters set forth in Section 6 is not satisfied, because of any termination pursuant to Section 8(ii) hereof, or because of any failure, refusal or inability on the part of the Copano Parties to comply with the terms or fulfill any of the conditions of this Agreement other than by reason of a default of the Underwriters, then each of the Copano Parties jointly and severally agrees to reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and expenses of their counsel) incurred by the Underwriters in connection herewith.

11. Research Analyst Independence. The Copano Parties acknowledge that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Issuers and/or the offering that differ from the views of their respective investment banking divisions. The Copano Parties hereby waive and release, to the fullest extent permitted by law, any claims that the Copano Parties may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Copano Parties by such Underwriters’ investment banking divisions. The Copano Parties acknowledge that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

12. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and any controlling persons referred to herein, and the affiliates, officers and directors of each Underwriter referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Notes from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

13. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Copano Parties and the Underwriters contained in this Agreement or made by or on behalf of the Copano Parties or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Notes and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Copano Parties or the Underwriters.

14. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act.

15. Miscellaneous.

(a) Authority of the Representatives. Any action by the Underwriters hereunder may be taken by the Representatives on behalf of the Underwriters, and any such action taken by the Representatives shall be binding upon the Underwriters.

All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted and confirmed by any standard form of telecommunication.

ANNEX A

Opinion of Xxxxxx & Xxxxxx L.L.P.

(a) Formation and Qualification of Copano Group. Each of (i) Copano Energy, L.L.C., a Delaware limited liability company (the “Company”), (ii) Copano Energy Finance Corporation, a Delaware corporation (“XxxXx”), (iii) Copano Pipelines Group, L.L.C., a Delaware limited liability company (“CPG”), (iv) Copano/Xxxx-Xxxxx Pipeline GP, L.L.C., a Delaware limited liability company (“CWDPL”), (v) CWDPL LP Holdings, L.L.C., a Delaware limited liability company (“CWDPL Holdings”), (vi) Copano Houston Central, L.L.C., a Delaware limited liability company (“CHC”), (vii) Copano Energy/Mid-Continent, L.L.C., a Delaware limited liability company (“Mid-Continent”), and (vii) Copano Energy/Rocky Mountains, L.L.C., a Delaware limited liability company (“Rocky Mountains”) (the Company, XxxXx, CPG, CHC, CWDPL, CWDPL Holdings, Mid-Continent, and Rocky Mountains, the “Copano Group”), has been duly formed and is validly existing as a limited liability company or corporation in good standing under the laws of its jurisdiction of formation with all limited liability company or corporate, as the case may be, power and authority necessary to own or lease its properties and to conduct its business, in each case in all material respects as described in the Registration Statement, the Time of Sale Information and the Prospectus. Each member of the Copano Group is duly registered or qualified to do business and is in good standing as a foreign limited liability company or corporation, as the case may be, in each jurisdiction set forth under its name on Appendix 1 to this opinion letter.

(b) Ownership of the Copano Group. The Company owns (i) 100% of the capital stock of XxxXx and (ii) 100% of the limited liability company interests of each of CPG, CHC, CWDPL, CWDPL Holdings, Mid-Continent and Rocky Mountains. All such limited liability company interests (including the common units representing limited liability company interests in the Company) or capital stock, as the case may be, have been duly authorized and validly issued in accordance with any applicable limited liability company agreement (the “Copano Group Operating Agreements”) and any applicable certificate of incorporation or organization, other charter documents or bylaws, as the case may be (collectively with the Copano Group Operating Agreements, the “Copano Group Operating Documents”) and are fully paid (to the extent required under the applicable Copano Group Operating Agreements) and non-assessable (except as such non-assessability may be affected by Sections 18-607 and 18-804 of the Delaware LLC Act); and all such interests are owned free and clear of all liens, encumbrances (except restrictions on transferability as described in the Registration Statement, the Time of Sale Information and the Prospectus), security interests, equities, charges and other claims (other than those arising under the Credit Agreement) (i) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming the Company is on file as of a recent date in the office of the Secretary of State of the State of Delaware or (ii) otherwise known to such counsel, without independent investigation, other than those created by or arising under the Delaware General Corporation Law (the “DGCL”) or the Delaware LLC Act.

(c) Authority. Each of the Copano Parties has full right, power and authority to execute and deliver this Agreement and the Notes and to perform its obligations hereunder and thereunder and under the Indenture (including each Guarantee set forth therein); and all action

Annex A - 1

required to be taken by such Copano Party for the due and proper authorization, execution and delivery of this Agreement, the Notes and the Indenture (including each Guarantee set forth therein) and the consummation of the transactions contemplated thereby has been duly and validly taken.

(d) Indenture.
