(c) Dispute Procedures. The Final Working Capital (as set forth in the Statement of Working Capital Calculation) shall become final and binding on Copano and Contributors on the thirtieth (30th) day following the date the Statement of Working Capital Calculation is received by Contributors Representative, unless prior to the expiration of such thirty-day period Contributors Representative delivers written notice to Copano of its disagreement. Contributors Representative’s written notice shall set forth all of its disputed items together with, to the extent reasonably practicable, its proposed changes thereto, including an explanation in reasonable detail of the basis on which Contributors Representative proposes such changes. Contributors shall be deemed to have agreed with all items and amounts contained in the Statement of Working Capital Calculation that are not specifically identified in such notice of disagreement.

If Contributors Representative has delivered a timely notice of disagreement, then Copano and Contributors Representative shall use their good faith efforts to reach agreement on the disputed items to determine the Final Working Capital.

If Copano and Contributors Representative have not signed an agreement resolving the disputed items by the sixtieth (60th) day following Contributors Representative’s receipt of the Statement of Working Capital Calculation, then the disputed items set forth in the notice of disagreement shall be submitted to the Independent Accountants for resolution within five (5) Business Days after the end of the foregoing sixty (60) day period.

The fees and expenses of the Independent Accountants shall be borne fifty percent (50%) by Contributors and fifty percent (50%) by Copano.

(d) Binding Effect. If a dispute notice is timely given pursuant to Section 2.4(c), the Final Working Capital shall be deemed determined on the date that the Independent Accountants give notice to Copano and Contributors Representative of their determination with respect to all disputes regarding the calculation thereof, or, if earlier, the date on which Copano and Contributors Representative agree in writing on the amount thereof, in which case the Final Working Capital Payment shall be calculated in accordance with such determination or agreement, as the case may be. Any determination of the Final Working Capital by the Independent Accountants, in compliance with the terms of Section 2.4(c), shall be final and binding upon Copano and Contributors.

(e) Payments. If the Final Working Capital exceeds the Estimated Working Capital Payment, then Copano shall pay to Contributors the amount of such excess, plus interest at the Specified Rate on the amount of such excess from (and including) the Closing Date to (but excluding) the date of payment. If the Final Working Capital is less than the Estimated Working Capital Payment, then Contributors shall pay to Copano the amount of such deficiency, plus interest at the Specified Rate on the amount of such deficiency from (and including) the Closing Date to (but excluding) the date of payment. Any payment shall be made within five (5) Business Days of the date the Final Working Capital is deemed to be finally determined pursuant to Section 2.4(d). Copano and Contributors agree that, unless otherwise required by applicable Law, all of the payments referenced in this Section 2.4 shall be treated as an adjustment to the Contribution Value for all Tax purposes.

2.5 Purchase Price Allocation. Within 120 days following the execution of this Agreement, the Parties, acting reasonably, shall agree upon the allocation of the Contribution Value (less the Employee Bonus Pool) for all purposes, including the filing of any Tax Returns. To the extent that a price adjustment occurs following calculation of the Final Working Capital, Copano and Contributors shall promptly make appropriate adjustments to such allocations, and such changed allocations shall then be the allocation that each Party uses for all purposes, including the filing of any Tax Returns (including, without limitation, Form 8594 and for purposes of Section 704 of the Code), except as otherwise required by a determination, as defined in Section 1313 of the Code.

Copano hereby represents and warrants to the Contributors that the following representations and warranties are as of the date hereof true and correct:

8.1 Organization and Existence. Copano is a limited liability company validly existing and in good standing under the laws of the State of Delaware. Copano has full limited liability company power and authority to own and hold the properties and assets it now owns and holds and to carry on its business as and where such properties are now owned or held and such business is now conducted. Copano is duly licensed or qualified to do business as a foreign limited liability company and is in good standing in the states in which the character of the properties and assets now owned or held by it or the nature of the business now conducted by it requires it to be so licensed or qualified, except where the failure to be so qualified or in good standing would not, singly or in the aggregate, reasonably be expected to have a material adverse effect on the ability of Copano to perform its obligations under this Agreement.

8.2 Authority and Approval. Copano has the limited liability company power and authority to execute and deliver this Agreement and the other Transaction Documents to which it is a party, to consummate the transactions contemplated hereby and thereby and to perform all the terms and conditions hereof and thereof to be performed by it. The execution and delivery by Copano of this Agreement and the other Transaction Documents to which it is a party, the performance by Copano of all the terms and conditions hereof and thereof to be performed by it and the consummation of the transactions contemplated hereby and thereby have been duly authorized and approved by all requisite limited liability company action of Copano, and no other limited liability company proceeding on the part of Copano is necessary to authorize this Agreement, the other Transaction Documents to which it is a party or the transactions contemplated herein or therein. This Agreement and the other Transaction Documents to which Copano is a party constitute or, if not yet executed, will at Closing constitute the valid and binding obligations of Copano, enforceable in accordance with their respective terms, except as such enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting enforcement of creditors’ rights generally and by general principles of equity (whether applied in a proceeding at law or in equity).

8.3 Brokerage Arrangements. Neither Copano nor any of its Affiliates have entered (directly or indirectly) into any agreement with any person, firm or corporation that would obligate the Contributors to pay any commission, brokerage or “finder’s fee” or other fee in connection with this Agreement or the transactions contemplated herein.

8.4 Contributors’ Units. Upon the consummation of the transactions contemplated hereby, all Units issued to the Contributors will have been issued and sold by Copano in accordance with all applicable securities Law (assuming the accuracy of the representations and warranties of the Contributors in Section 4.8, Section 5.8 and Section 6.8), and will be duly authorized, validly issued and fully paid. Upon issuance at the Closing, the Units issued to the Contributors will be free of any Liens other than those created by the Contributors, those arising

-34-

under applicable securities Law, those set forth in the Copano LLC Agreement and those arising under the Transaction Documents.

8.5 Securities Laws. Copano is an accredited investor within the meaning of Rule 501(a) under the Securities Act, and the Partnership Interests being acquired by Copano pursuant to this Agreement are being acquired for Copano’s own account and not with a view toward, or for sale in connection with, any distribution thereof except in compliance with applicable United States federal and state securities laws. Copano is aware that no Governmental Entity has made any finding or determination as to the fairness of an investment in the Partnership Interests, nor any recommendation or endorsement with respect thereto. Copano acknowledges and understands that (i) the acquisition of the Partnership Interests has not been registered under the Securities Act in reliance on an exemption therefrom; (ii) the Partnership Interests acquired by Copano will, upon acquisition, be characterized as “restricted securities” under state and federal securities Laws; and (iii) such Partnership Interests may be sold without registration under such state and federal securities Laws only in certain limited circumstances. Copano has such knowledge and experience in financial and business matters so as to be capable of evaluating the merits and risks of its investment in the Partnership Interests and is capable of bearing the economic risks of such investment.

8.6 SEC Filings.

(a) Copano has heretofore filed all forms, reports, registration statements, definitive proxy statements, schedules and other materials with the SEC required to be filed pursuant to the Exchange Act or other federal securities Laws since December 31, 2006 (the “SEC Reports”).

The SEC Reports, when filed and as amended from time to time, did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, Copano shall have no liability with respect to any current report on Form 8-K of Copano that was “furnished” rather than “filed” with the SEC.

(b) The financial statements of Copano, included in the SEC Reports, including the related notes thereto including the related notes thereto (the “Copano Financial Statements”), when filed (i) were prepared from, and in accordance with, the books and records of Copano, (ii) complied in all material respects with applicable accounting requirements and with the published rules and regulations of the SEC with respect thereto as of their respective dates, (iii) were prepared in accordance with GAAP applied on a consistent basis during the periods covered thereby (except as may be indicated in the notes thereto), provided, however, that any unaudited financial statements are subject to normal year-end adjustments and lack footnotes otherwise required by GAAP, and (iv) fairly presented in all material respects the

-35-

consolidated financial position and the consolidated results of operations and cash flows of the Copano as of the dates thereof or for the periods presented therein.

8.7 No Conflict; Consents. The execution and delivery of this Agreement by Copano and the consummation of the transactions contemplated hereby by Copano do not and shall not:

(a) violate any Law applicable to Copano or require any filing with, consent, approval or authorization of, or notice to, any Governmental Entity, except (i) where such violation would not have a material adverse effect on the ability of Copano to perform its obligations under this Agreement, or (ii) for compliance with and filings to be made under the HSR Act or the Exchange Act;

(b) violate any Organizational Document of Copano;

(c) require any filing with or permit, consent or approval of, or the giving of any notice to, any other Person, except (i) where the failure to obtain such permit, consent or approval would not have a material adverse effect on the ability of Copano to perform its obligations under this Agreement or (ii) under the Nasdaq Marketplace Rules; or

(d) except where such event would result in a material adverse effect on the ability of Copano to perform its obligations under the Transaction Documents, (i) breach any material Contract to which Copano is a party or by which Copano may be bound, (ii) result in the termination of any such material Contract, (iii) result in the creation of any Lien under any material Contract or (iv) constitute an event that, after notice or lapse of time or both, would result in any such breach, termination or creation of a Lien.

8.8 Litigation. As of the date of this Agreement, except as disclosed in the SEC Reports, (a) there are no Proceedings before any Governmental Entity pending or threatened in writing against Copano that would reasonably be expected to have a material adverse effect on the ability of Copano to perform its obligations under this Agreement and (b) there are no Orders binding upon Copano that would reasonably be expected to have a material adverse effect on the ability of Copano to perform its obligations under this Agreement.

8.9 Absence of Certain Changes. From December 31, 2006 until the date of this Agreement, except as disclosed in the SEC Reports, (a) there has not been any material adverse effect on Copano and (b) the business of Copano has been conducted only in the ordinary course.

8.10 Financial Ability. Copano has, through a combination of cash on hand and funds readily and unconditionally available under existing lines of credit, funds sufficient to fund the Estimated Cash Price.

Except for the representations and warranties made by any of the Contributors in this Agreement or in any certificate or written statement furnished or to be furnished to Copano pursuant to this Agreement or in connection with the transactions contemplated hereby, Copano acknowledges that there are no representations or warranties, whether oral or written, express or implied, as to the condition (financial or otherwise), assets, liabilities, operations,

-36-

business or prospects of the Partnership, as to the accuracy or completeness of information obtained by Copano during its investigation of the Partnership, and in entering into and performing this Agreement, Copano has relied and will rely solely upon the representations and warranties of Contributors in this Agreement and Copano’s independent investigation of, and judgment with respect to, the Partnership, its value and the Partnership Interests.

section of the Agreement or in a particular section of any Schedule shall not be limited to that particular section or schedule, whether or not a specific cross-reference is included, but only to the extent that the applicability of such disclosure is appropriate and reasonably apparent.

The Parties shall coordinate their initial filing of the notification

-40-

and report form so that such filings are made on the same day. The Parties shall each keep the other Parties fully advised with respect to any requests from or communications with the DOJ or the FTC and shall consult with the other Parties with respect to all filings and responses thereto.

9.7 Cooperation.

(a) The Parties agree to cooperate with each other and to use commercially reasonable efforts to cause all of the conditions precedent to Closing to be satisfied as promptly as practicable. In addition, each Contributor shall cooperate with Copano, upon Copano’s request, to obtain the consent to the transactions contemplated by this Agreement of any third Person that may be required under any Law or any Contract to which the Partnership or any of its Subsidiaries is a party. Between the date of this Agreement and Closing, the Parties agree to use Reasonable Efforts to obtain from Rife Production Company, a dedication to Tri-County of all of Rife Production Company’s gas production in approximately 10,000 acres of leaseholds in Wise, Cooke and Montague Counties, Texas.

(a) Prior to the Closing, the Contributors shall use Reasonable Efforts to obtain that certain consent of I-35/View 36, LLC set forth in Schedule 7.5 and the consents of I-35/View 36, LLC set forth in Schedule 11.7 (collectively, the “North Denton Consents”). If the Contributors fail to obtain the North Denton Consents prior to the Closing, (i) the Contributors shall cause the Partnership to distribute prior to the Closing all of the Partnership’s membership interests in North Denton Pipeline, L.L.C. to a Contributor, (ii) the Contributors shall deliver to Copano on or prior to the Closing date evidence of such transfer in form and substance reasonably satisfactory to Copano, and (iii) such membership interests in North Denton Pipeline, L.L.C. shall be retained by the Contributor to whom it was assigned. Notwithstanding anything herein, no Party shall have the right to terminate or delay the Closing as a result of any failure to obtain the North Denton Consents, provided that the Contributors have complied with this Section 9.8(a).

(b) After the Closing Date, in the event that any Contributor and/or John Schmitz or any affiliated entity controlled by him (collectively, the “North Denton Acquiror”) acquires all of the membership interests of North Denton Pipeline, L.L.C. held by I-35/View 36, LLC, the Contributors shall use Reasonable Efforts to obtain the agreement of the North Denton

-41-

Acquiror(s) to transfer such interests to Copano (or such Affiliate thereof as requested by Copano). In the event that the agreement described in the foregoing sentence is obtained, or the North Denton Consents are obtained, and there exists no material liabilities or obligations in excess of those existing as of the date of this Agreement (as reasonably determined by Copano) associated with the interests in or of North Denton Pipeline L.L.C., Copano (or its designated affiliate) shall acquire from the Contributors, and the Contributors shall promptly cause the transfer to Copano of, the membership interests in North Denton Pipeline, L.L.C. acquired by the Contributors from the Partnership and/or I-35/View 36, LLC, and each shall execute such instruments as reasonably required by Copano in connection therewith. Simultaneously with such sale, transfer and assignment, Copano shall pay to the Contributors one hundred thousand dollars ($100,000.00) by wire transfer of immediately available funds. In the event that there exists any material liabilities or obligations associated with the interests in or of North Denton Pipeline L.L.C. in excess of those existing as of the date of this Agreement, then Copano may, but is not required to, acquire the membership interests in North Denton Pipeline, L.L.C. or consummate the transaction described in the two immediately foregoing sentences. For the avoidance of doubt, the immediately foregoing described amount shall be in addition to, and not part of, any other amounts owed hereunder to the Contributors.

(e) by Copano upon the occurrence of an event or other occurrence that, individually or in the aggregate, has had a Material Adverse Effect; or

ARTICLE 13

TAX MATTERS

13.1 Liability for Taxes.

(a) For purposes of this Agreement:

(i) “Tax” or “Taxes” means all taxes, however denominated, including any interest, penalties or other additions to tax that may become payable in respect thereof, imposed by any federal, state, local or foreign government or any agency or political subdivision of any such government, which taxes shall include, without limiting the generality of the foregoing, all income or profits taxes (including, but not limited to, federal income taxes and state income taxes), gross receipts taxes, net proceeds taxes, alternative or add-on minimum, sales taxes, use taxes, real property gains or transfer taxes, ad valorem taxes, property taxes, value-added taxes, franchise taxes, production taxes, severance taxes, windfall profit taxes, withholding taxes, payroll taxes, employment taxes, excise taxes and other obligations of the same or similar nature to any of the foregoing;

(ii) “Tax Returns” means all reports, estimates, declarations of estimated Tax, information statements and returns relating to, or required to be filed in connection with, any Taxes.

(b) The Contributors shall be liable for, and shall indemnify and hold Copano, the Partnership and their respective Affiliates harmless from any Taxes, together with any costs, expenses, losses or damages, including reasonable expenses of investigation and attorneys’ and accountants’ fees and expenses incurred in investigating and preparing for any proceeding, arising out of or incident to the determination, assessment or collection of Taxes (“Tax Losses”) (i) imposed on or incurred by the Partnership or any of its Subsidiaries or for which the Partnership or any of its Subsidiaries is otherwise liable with respect to any period ending prior to or with the Effective Date (the “Pre-Effective Time Period”), or (ii) attributable to a breach by the Contributors of Section 7.10, this Article 13 or any other representation, warranty or covenant with respect to Taxes in this Agreement (without giving effect to any materiality or knowledge qualifiers that may be contained therein and without regard to any scheduled items);

-45-

or (iii) of any member of an affiliated, consolidated, combined or unitary group of which the Partnership or any of its Subsidiaries (or any predecessor of any of them) is or was a member on or prior to the Effective Date by reason of Treasury Regulation § 1.1502-6(a) or any analogous or similar state or local law, or (iv) of any other Person for which the Partnership or any of its Subsidiaries is or has been liable as a transferee or successor, by contract or otherwise with respect to the Pre-Effective Time Period; provided, however, that any such Tax described herein shall not be indemnified to the extent such Tax was accrued on the Effective Date Balance Sheet or otherwise taken into account in determining the Final Working Capital.

(c) Copano shall be liable for, and shall indemnify and hold the Contributors, and their respective Affiliates harmless from any Tax Losses (i) imposed on or incurred by the Partnership and any of its Subsidiaries with respect to any period ending after the Effective Date or (ii) attributable to a breach by Copano of any covenant of Copano with respect to Taxes in this Agreement.

(d) Whenever it is necessary for purposes of this Article 13 to determine the portion of any Taxes imposed on or incurred by the Partnership or any of its Subsidiaries for a taxable period beginning before and ending after the Effective Date which is allocable to the Pre-Effective Time Period, the determination shall be made, in the case of property or ad valorem taxes or franchise taxes (which are measured by, or based solely upon capital, debt or a combination of capital and debt), on a per diem basis and, in the case of other Taxes, by assuming that the Pre-Effective Time Period constitutes a separate taxable period of the Partnership or such Subsidiary and by taking into account the events occurring during such period (except that exemptions, allowances and deductions for a taxable period beginning before and ending after the Effective Date that are calculated on an annual or periodic basis, such as the deduction for depreciation, shall be apportioned to the Pre-Effective Time Period ratably on a per diem basis). Notwithstanding anything to the contrary herein, any franchise Tax paid or payable with respect to the Partnership or any of its Subsidiaries shall be allocated to the taxable period during which the income, operations, assets or capital comprising the base of such Tax is measured, regardless of whether the right to do business for another taxable period is obtained by the payment of such franchise Tax.

(e) Copano agrees to pay to the Contributors any refund received after the Closing Date by Copano or its Affiliates, including the Partnership, in respect of any Taxes for which the Contributors are liable under clause (b) of this Section 13.1. The Contributors agree to pay to Copano any refund received by the Contributors or their affiliates in respect of any Taxes for which Copano is liable under clause (c) of this Section 13.1. The Parties shall cooperate in order to take all necessary steps to timely claim any such refund. Any such refund received by a Party or its Affiliate for the account of the other Party shall be paid to such other Party within 10 days after such refund is received.

13.2 Tax Returns.

(a) With respect to any Tax Return covering a taxable period ending on or before the Effective Date that is required to be filed after the Effective Date with respect to the Partnership or any of its Subsidiaries, the Contributors shall cause such Tax Return to be prepared, shall cause to be included in such Tax Return all Tax items required to be included

-46-

therein, shall cause such Tax Return to be filed timely with the appropriate Taxing Authority, and shall be responsible for the timely payment (and entitled to any refund) of all Taxes due with respect to the period covered by such Tax Return, except to the extent that such Taxes were accrued on the Effective Date Balance Sheet or otherwise taken into account in determining final Working Capital.

(b) Subject to Section 13.2(c), With respect to any Tax Return covering a taxable period beginning on or before the Effective Date and ending after the Effective Date that is required to be filed after the Effective Date with respect to the Partnership or any of its Subsidiaries, Copano shall cause such Tax Return to be prepared, shall cause to be included in such Tax Return all Tax items required to be included therein, shall furnish a copy of such Tax Return to the Contributors, shall file timely such Tax Return with the appropriate Taxing Authority, and shall be responsible for the timely payment of all Taxes due with respect to the period covered by such Tax Return. Copano shall determine, in accordance with the provisions of Section 13.1(d) of the Agreement, the amount of Tax due with respect to the Pre-Effective Time Period (the “Contributors’ Tax”) and shall notify the Contributors of its determination of the Contributors’ Tax. Within five days after filing such Tax Return, the Contributors shall pay to Copano an amount equal to the excess of (x) the Contributors’ Tax over (y) the amount accrued for the Contributors’ Tax and any estimated or other payments made for such tax prior to the Effective Date on the Effective Time Balance Sheet or otherwise taken into account as a liability in determining the adjustments to the purchase price in Section 2.4. However, in the event the excess of (x) over (y) in the foregoing sentence is a negative number, Copano shall be required to pay such difference to the Contributors within such five-day period. Any refund attributable to Tax Returns filed pursuant to this Section 13.2(b) shall be apportioned between Copano and the Contributors in a manner consistent with calculation of the Contributors’ Tax.

(c) Copano shall, with respect to any Tax Return for which Copano is responsible under Section 13.2(b) for preparing and filing, make such Tax Return and Tax work papers available for review by the Contributors if the Tax Return is with respect to Taxes for which the Contributors may be liable (in whole or in part) hereunder or under applicable law. Copano shall make such return and work papers available for review sufficiently in advance of the due date for filing such Tax Returns to provide the Contributors with a meaningful opportunity to analyze and comment on such Tax Returns and have such Tax Returns modified before filing. Copano will consider all comments from the Contributors in good faith.

(d) Any Tax Return which includes or is based on the operations, ownership, assets or activities of the Partnership or any of its Subsidiaries or Contributors for any taxable period beginning before and ending after the Effective Date, and any Tax Return in respect of any Taxes for which the Contributors may be liable (in whole or in part) hereunder shall be prepared in accordance with past Tax accounting practices used with respect to the Tax Returns in question (unless such past practices are no longer permissible under the applicable law), and to the extent any items are not covered by past practices (or in the event such past practices are no longer permissible under the applicable tax law), in accordance with reasonable tax accounting practices selected by the filing Party with respect to such Tax Return under this Agreement with the consent (not to be unreasonably withheld or delayed) of the non-filing Party.

-47-

(e) Unless required by law, Copano shall not file an amended Tax Return for any period ending on or prior to the Effective Date without the prior written consent of the Contributors.

13.3 Tax Proceedings. In the event Copano or any of its Affiliates receives notice (the “Proceeding Notice”) of any examination, claim, adjustment, or other proceeding with respect to the liability of the Partnership or any of its Subsidiaries for Taxes for any period for which the Contributors are or may be liable under Section 13.1, Copano shall notify the Contributors in writing thereof (the “Copano Notice”) no later than the earlier of (a) thirty (30) days after the receipt by Copano or any of its affiliates of the Proceeding Notice or (b) ten (10) days prior to the deadline for responding to the Proceeding Notice. Such Copano Notice shall contain factual information describing any asserted liability for Taxes in reasonable detail and shall be accompanied by copies of any notice or other documents received from any Taxing Authority with respect to such matter. As to any such Taxes for which the Contributors are or may be liable under Section 13.1, the Contributors shall be entitled at their expense to control or settle the contest of such examination, claim, adjustment, or other proceeding, provided (i) the Contributors notify Copano in writing that they desire to do so no later than the earlier of (1) thirty (30) days after receipt of the Copano Notice or (2) five (5) days prior to the deadline for responding to the Proceeding Notice, and (ii) the Contributors may not, without the consent of Copano, agree to any settlement which would result in an increase in the amount of Taxes for which Copano, the Contributors or the Partnership or any of its Subsidiaries is or may be liable under Section 13.1. The Contributors shall be required to pay any Taxes required to be paid in connection with any examination, claim, adjustment or other proceeding, including, without limitation, any prepayment of Tax required to obtain the jurisdiction of a court. The Parties shall cooperate with each other and with their respective affiliates, and shall consult with each other, in the negotiation and settlement of any proceeding described in this Section 13.3. Copano will provide, or cause to be provided, to the Contributors necessary authorizations, including powers of attorney, to control any proceedings which the Contributors are entitled to control pursuant to this Section 13.3. The Contributors shall pay to Copano the amount of any Tax Losses Copano may become entitled to by reason of the provisions of this Article 13 within fifteen (15) days after the extent of any Tax liability has been determined by a final judgment or decree of a Court or a final and binding settlement with a Taxing Authority having jurisdiction thereof.

13.4 Cooperation and Exchange of Information. Copano and the Contributors shall cooperate fully, and shall cause the Partnership and its Subsidiaries, as the case may be, to cooperate fully, as and to the extent reasonably requested by the other Parties, in connection with the filing of Tax Returns pursuant to this Article 13 and any proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information which are reasonably relevant to any such proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Contributors and Copano agree to retain all books and records in their possession or in the possession of their respective affiliates with respect to Tax matters pertinent to the Contributors, Partnership or its Subsidiaries relating to any taxable period beginning before the Closing Date until the earlier of six years after the Closing Date or the expiration of the applicable statute of limitations of the respective taxable periods, and to abide by all record retention agreements entered into with any Taxing Authority, and thereafter, upon request, allow Copano to take possession of such books and records.

-48-

The Contributors further agree, upon request, to use their reasonable best efforts to obtain any certificate or other document from any Taxing Authority or any other person or entity as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed on Copano, the Contributors, the Partnership or any of its Subsidiaries. Copano and the Contributors further agree, upon request, to provide the other Party with all information regarding the Contributors, the Partnership and its Subsidiaries that either Party may be required to report to any Taxing Authority. Any information obtained pursuant to this Section 13.4 shall be kept confidential, except as may be otherwise necessary in connection with the filing of Tax Returns or claims for refund or in conducting any audit or other proceeding. Each Party shall provide the cooperation and information required by this Section 13.4 at its own expense.

13.5 Tax Covenants. Copano and the Contributors agree to the following covenants:

(a) The Parties agree to treat the contribution of the Partnership Interests in exchange for Units under Section 2.2(a) as a transaction pursuant to Code Section 721.

(b) Copano covenants that for until the earlier of (i) two years following the Effective Time or (ii) the date that all of the Units transferred pursuant to Sections 2.2(a) and 2.2(b) have been sold in a transaction resulting in a basis adjustment under Code Section 743 for the benefit of the transferee, that Copano and its Affiliates will not dispose of any Partnership Interests (or underlying assets) acquired by Copano pursuant to Section 2.1 if any such disposition or series of dispositions would accelerate or increase income or other positive adjustments with respect to the Units transferred to the Contributors pursuant to Sections 2.2(a) and 2.2(b). Contributors agree to notify Copano promptly upon the occurrence of any such transfer of Units resulting in such a basis adjustment.

(c) The Parties agree that the difference between the fair market value and the adjusted tax basis of any Section 704(c) property (within the meaning of Treasury Regulation Section 1.704-3(a)(3)) acquired by Copano pursuant to this Agreement will be taken into account under the “remedial method” as described in Treasury Regulation Section 1.704-3(d).

(d) Notwithstanding anything to the contrary in this Agreement Copano shall have no indemnity obligations to Contributor Indemnitees for any Taxes or Tax consequences (including recognition of deferred gain) incurred by any Contributor in connection with any sale of Units by such Contributor.

(e) The Parties agree to treat the Units as outstanding Common Units for all purposes of the Code prior to the date of conversion to Common Units and neither such Units, nor the Common Units into which they are convertible shall be subject to Section 483 of the Code.

(f) The Parties agree to treat the Escrowed Units as owned by the Contributors for federal income tax purposes and that such Escrowed Units shall not be subject to Section 483 of the Code.

(g) The Parties agree to allocate items of income and loss to the Units in the same manner as income and loss are allocated to the Common Units under the Copano LLC Agreement.

-49-

13.6 Survival. Anything to the contrary in this Agreement notwithstanding, the representations, warranties, covenants, agreements, rights and obligations of the Parties hereto with respect to any Tax matter covered by this Agreement shall survive the Closing and shall terminate three (3) years thereafter, except to the extent that the person who is entitled to indemnity payments hereunder by reason of any breach thereof has prior to that time provided written notice to any person who would be required to make such an indemnity payment of the breach thereof.

13.7 Conflict. In the event of a conflict between the provisions of this Article 13 and any other provisions of this Agreement, the provisions of this Article 13 shall control.

-52-

Nothing in this Section 15.2 shall apply to liability with respect to Taxes, for which liability shall be as set forth in Article 13.

(c) Transportation LLC shall indemnify and hold the Copano Indemnitees harmless from and against any and all Damages suffered by the Copano Indemnitees as a result of, caused by, arising out of, or in any way relating to (i) any breach of a representation or warranty of Transportation LLC in this Agreement and (ii) any breach of any agreement or covenant on the part of Transportation LLC under this Agreement, subject to Section 14.2(a) and Section 15.8. Nothing in this Section 15.2 shall apply to liability with respect to Taxes, for which liability shall be as set forth in Article 13.

15.3 Demands. Each indemnified party hereunder agrees that promptly upon its discovery of facts giving rise to a claim for indemnity under the provisions of this Agreement, including receipt by it of notice of any demand, assertion, claim, action or proceeding, judicial or otherwise, by any third party (such third party actions being collectively referred to herein as the “Indemnity Claim”), with respect to any matter as to which it claims to be entitled to indemnity under the provisions of this Agreement, it will give prompt notice thereof in writing to the indemnifying party, together with a statement of such information respecting any of the foregoing as it shall have. Such notice shall include (a) a formal demand for indemnification under this Agreement and the facts that otherwise form the basis of such claim, (b) the estimate of the amount of such claim (which estimate shall not be conclusive of the final amount of such claim) and an explanation of the calculation of such estimate, including a statement of any significant assumptions employed therein, and (c) the date on and manner in which the party delivering such notice became aware of the existence of such claim. The failure to notify the indemnifying party shall not relieve it of any liability that it may have to any indemnified party with respect to such Indemnity Claim except to the extent the indemnifying party shall have been materially prejudiced by such failure or to the extent such notice was provided after the expiration of the relevant survival period set forth in Section 14.2.

15.4 Right to Contest and Defend. The indemnifying party shall be entitled at its cost and expense to contest and defend by all appropriate legal proceedings any Indemnity Claim with respect to which it is called upon to indemnify the indemnified party under the provisions of this Agreement; provided, that written notice of the intention to so contest shall be delivered by the indemnifying party to the indemnified party within 20 days from the date of receipt by the indemnifying party of notice by the indemnified party of the assertion of the Indemnity Claim. Any such contest may be conducted in the name and on behalf of the indemnifying party or the indemnified party as may be appropriate. Such contest shall be conducted and prosecuted diligently to a final conclusion or settled in accordance with this Section 15.4 by reputable counsel employed by the indemnifying party and not reasonably objected to by the indemnified party, but the indemnified party shall have the right but not the obligation to participate in such proceedings and to be represented by counsel of its own choosing at its sole cost and expense. The indemnifying party shall have full authority to determine all action to be taken with respect thereto; provided, however, that the indemnifying party will not have the authority to subject the

-53-

indemnified party to any obligation whatsoever, other than the performance of purely ministerial tasks or obligations not involving material expense. If the indemnifying party does not elect to contest any such Indemnity Claim or elects to contest such Indemnity Claim but fails diligently and promptly to prosecute or settle such claim, the indemnifying party shall be bound by the result obtained with respect thereto by the indemnified party. If the indemnifying party shall have assumed the defense of an Indemnity Claim, the indemnified party shall agree to any settlement, compromise or discharge of an Indemnity Claim that the indemnifying party may recommend and that by its terms obligates the indemnifying party to pay the full amount of the liability in connection with such Indemnity Claim, which releases the indemnified party completely in connection with such Indemnity Claim and which would not otherwise adversely affect the indemnified party.

Notwithstanding the foregoing, the indemnifying party shall not be entitled to assume the defense of any Indemnity Claim (and shall be liable for the reasonable fees and expenses of counsel incurred by the indemnified party in defending such Indemnity Claim) if the Indemnity Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the indemnified party which the indemnified party reasonably determines, after conferring with its outside counsel, cannot be separated from any related claim for money damages. If such equitable relief or other relief portion of the Indemnity Claim can be so separated from that for money damages, the indemnifying party shall be entitled to assume the defense of the portion relating to money damages.

15.5 Cooperation. If requested by the indemnifying party, the indemnified party agrees to cooperate with the indemnifying party and its counsel in contesting any Indemnity Claim that the indemnifying party elects to contest or, if appropriate, in making any counterclaim against the person asserting the Indemnity Claim, or any cross-complaint against any person, and the indemnifying party will reimburse the indemnified party for any reasonable costs and expenses incurred by it in so cooperating. At no cost or expense to the indemnified party, the indemnifying party shall cooperate with the indemnified party and its counsel in contesting any Indemnity Claim.

15.6 Right to Participate. The indemnified party agrees to afford the indemnifying party and its counsel the opportunity to be present at, and to participate in, conferences with all persons, including Governmental Entities, asserting any Indemnity Claim against the indemnified party or conferences with representatives of or counsel for such persons.

15.7 Payment of Damages. The indemnification required hereunder shall be made by periodic payments of the amount thereof during the course of the investigation or defense, within thirty (30) days as and when reasonably specific bills are received or loss, liability, claim, damage or expense is incurred and reasonable evidence thereof is delivered. In calculating any amount to be paid by an indemnifying party by reason of the provisions of this Agreement, the amount shall be reduced by all reimbursements (including, without limitation, insurance proceeds) finally credited to or received by the other party related to the Damages.

-54-

15.8 Limitations on Indemnification. Notwithstanding anything to the contrary in this Agreement:

(a) To the extent the Copano Indemnitees are entitled to indemnification for Damages pursuant to Section 15.2, for breaches of representations or warranties in this Agreement by any Contributor, the Contributor shall not be liable for those Damages, and to the extent the Contributor Indemnitees are entitled to indemnification for Damages pursuant to Section 15.1 for breaches of representations or warranties in this Agreement by Copano, Copano shall not be liable for those Damages, unless:

(i) Damages attributable to any single Indemnity Claim is in excess of the Claim Threshold; and

(ii) the aggregate amount of all Damages in excess of the Claim Threshold exceeds the Deductible Amount, and then such liability shall only be to the extent of any such excess.

(b) In addition, to the extent the Copano Indemnitees are entitled to indemnification for Damages pursuant to Section 15.2, the Copano Indemnitees’ sole and exclusive recourse and remedy shall be against the Escrowed Units in the possession of the Escrow Agent and which the Escrow Agent is not otherwise obligated to release from escrow in accordance with this Agreement and the Escrow Agreement. Neither the Contributors nor any Contributor Indemnitees shall have any personal liability for any Indemnity Claim of the Copano Indemnitees. To the extent the Contributor Indemnitees are entitled to indemnification for Damages pursuant to Section 15.2, Copano shall not be liable for Damages that exceed, in the aggregate, $5,000,000 in excess of the Deductible Amount.

(c) No Contributor shall have any duty or obligation to indemnify any Copano Indemnitee for any Indemnity Claim for which Copano fails to provide notice to the Contributors within the Claim Period. Copano shall have no duty or obligation to indemnify any Contributor Indemnitee for any Indemnity Claim for which Contributors fail to provide notice to Copano within the Claim Period.

(d) Notwithstanding anything to the contrary in this Agreement, the limitations in Section 15.8 shall not apply with respect to (i) breaches of any Fundamental Representation by any Contributor or (ii) breaches of any representation or warranty set forth in Sections 8.1, 8.2, 8.3, 8.4, 8.5, 8.7(b) or 8.11 by Copano.

(e) In addition to the foregoing limitations, the Contributors shall have no liability for a breach of any representation and warranty in Section 7.12, unless, prior to the end of the Claim Period, Copano shall have suffered Damages resulting directly from such breach in excess of $10,000,000. If, prior to the end of the Claim Period, Copano suffers Damages in excess of $10,000,000 resulting directly from such breach and delivers notice to the Contributors during the Claim Period, any indemnification obligation of the Contributors to Copano shall be limited to amounts in excess of said $10,000,000, and each of Sections 15(b) and 15(c) also shall apply to such excess amount. Notwithstanding the foregoing, any Damages suffered by Copano as a result of a breach of a representation and warranty in Section 7.12 by the Contributors shall

-55-

apply against the Deductible Amount for purposes of determining whether Copano is entitled to indemnification pursuant to Section 15.2 and Section 15.8(a) with respect to any other breaches of a representation or warranty in this Agreement by Contributors.

15.9 Escrowed Units.

(a) Copano shall cause the Escrowed Units to be deposited on the Closing Date with the Escrow Agent to be held in trust pursuant to the terms hereof and the terms of the Escrow Agreement. As between the Contributors and Copano, in the event of a conflict between the terms and conditions of the Escrow Agreement and the terms and conditions of this Agreement, the terms and conditions of this Agreement shall control. The Escrowed Units will be used to satisfy any indemnification obligations of any Contributor as described in Section 15.2 which are asserted by Copano within the Claim Period, subject to the limitations of Section 15.8.

(b) If Copano asserts an Indemnity Claim under Section 15.2 on or before the end of the Claim Period, and the Indemnifying Party does not dispute such claim, Copano shall be entitled to indemnification by the Indemnifying Party in accordance with this Article 15 by receiving from the Escrow Agent a number of Escrowed Units equal to the quotient of (i) the amount of such undisputed claim divided by (ii) the average closing price per Common Unit over the 10 Business Days ending on the last Business Day preceding the day of the execution of the release instructions to the Escrow Agent, rounded up or down to the nearest whole number of Units, and the Parties shall promptly jointly execute and deliver to the Escrow Agent written instructions instructing the Escrow Agent to release and deliver to Copano such number of Escrowed Units in accordance with the terms of and in the manner set forth in such instructions. If, however, any Contributor disputes such claim, Copano shall not be entitled to receive any Escrowed Units with respect to such claim prior to resolution of such dispute in accordance with this Agreement, other than a number of Escrowed Units in an amount equal to any amount that is not in dispute with respect to such claim.

(c) (i) Provided all indemnification obligations of Contributors to Copano under this Article 15 relating to a breach of a Fundamental Representation or a Partnership Interest Representation for which Copano has asserted an Indemnity Claim, if any, have been satisfied (including the obligation to pay any Indemnity Claim relating thereto) prior to the expiration of the six-month anniversary of the Closing Date of this Agreement, and no dispute then exists as to any Indemnity Claim notified by Copano to Contributors hereunder prior to the six-month anniversary of the Closing Date relating to a breach of a Fundamental Representation or a Partnership Interest Representation, the Parties shall, on the first Business Day immediately following the six-month anniversary of the Closing Date, jointly execute and deliver to the Escrow Agent written instructions instructing the Escrow Agent to release and deliver to the Contributors the Early Release Escrowed Units in accordance with the terms of and in the manner set forth in such instructions. To the extent there exists an Indemnity Claim pursuant to this Article 15 relating to a breach of a Fundamental Representation or a Partnership Interest Representation that has been notified by Copano to Contributors hereunder, but not satisfied in full by Contributors prior to the expiration of the six-month anniversary of the Closing Date, the Parties shall, on the first Business Day immediately following the six-month anniversary of the Closing Date, jointly execute and deliver to the Escrow Agent written instructions instructing the

-56-

Escrow Agent to release and deliver to the Contributors the Early Release Escrowed Units in accordance with the terms of and in the manner set forth in such instructions; provided, however, that a number of Escrowed Units equal in value (based upon the average closing price per Common Unit over the 10 Business Days ending on the last Business Day preceding the six-month anniversary of the Closing Date) to the maximum possible amount of such claim or claims reasonably believed by the Parties hereto to be due or likely to be due hereunder (or, in the event of a dispute between the Parties with respect thereto, the higher of the two estimates) will be withheld from the Early Release Escrowed Units and will continue to be held by the Escrow Agent pursuant to the terms of hereof and the terms of the Escrow Agreement until such claim or claims have been fully resolved and the Escrow Agreement shall be deemed to be extended accordingly.

(ii) Provided all indemnification obligations of Contributors to Copano for Indemnity Claims for which Copano provides notice to the Contributors within the Claim Period under this Article 15 have been satisfied (including the obligation to pay any such Indemnity Claim, if any) prior to the expiration of the Claim Period, and no dispute then exists as to any Indemnity Claim (including with respect to a Fundamental Representation or a Partnership Interest Representation) notified by Copano to Contributors hereunder prior to the expiration of the Claim Period, the Parties shall, on the first Business Day immediately following the expiration of the Claim Period, jointly execute and deliver to the Escrow Agent written instructions instructing the Escrow Agent to release and deliver to the Contributors the remaining Escrowed Units in accordance with the terms of and in the manner set forth on such instructions. To the extent there exists an Indemnity Claim pursuant to this Article 15 that has been notified by Copano to Contributors hereunder within the Claim Period, but not satisfied in full by Contributors prior to the expiration of the Claim Period, the Parties shall, on the first Business Day immediately following the expiration of the Claim Period, jointly execute and deliver to the Escrow Agent written instructions instructing the Escrow Agent to release and deliver to the Contributors the remaining Escrowed Units in accordance with the terms of and in the manner set forth on such instructions; provided, however, that a number of Escrowed Units equal in value (based upon the average closing price per Common Unit over the 10 Business Days ending on the last Business Day preceding the Claim Period) to the maximum possible amount of such claim or claims reasonably believed by the Parties hereto to be due or likely to be due hereunder (or, in the event of a dispute between the Parties with respect thereto, the higher of the two estimates) will be withheld from the remaining Escrowed Units and will continue to be held by the Escrow Agent pursuant to the terms of the Escrow Agreement until such claim or claims have been fully resolved and the Escrow Agreement shall be deemed to be extended accordingly.

(d) The fees and expenses of the Escrow Agent shall be borne 50% by Contributors and 50% by Copano.

(e) Notwithstanding anything herein or in the Transaction Documents to the contrary, the Contributors shall have full voting rights with respect to each Escrowed Unit during the period from the Closing Date unless and until such Escrowed Units are released to Copano from escrow pursuant to the terms of this Section 15.9.

(f) To the extent requested by the Contributors, simultaneously with any instructions to the Escrow Agent in accordance with Sections 15.9(a), (b) or (c) to release any

-57-

Escrowed Units to the Contributors, Copano shall cause the cancellation of certificated Escrowed Units and issuance of replacement certificated Units to the Persons and in the denominations requested in writing by the Contributors prior to the issuance of such instructions.

(g) Subject to the schedule set forth in Exhibit A, Units held by the Contributors shall be converted to Common Units prior to the conversion of Units held by the Escrow Agent pursuant to the terms of this Section 15.9. Any Common Units held by the Escrow Agent shall be distributed first to Contributors prior to the distribution of Units held by the Escrow Agent. Any dividends or other distribution on Common Units held by the Escrow Agent shall be paid and distributed to the Contributors Representative and shall not be a part of the assets covered by the Escrow Agreement.

15.10 Sole Remedy. Subject to Section 16.13, the indemnifications and remedies expressly set forth in Article 13, with respect to Taxes, and Article 15, with respect to all matters other than Taxes, shall, from and after the Closing, constitute the sole and exclusive relief and remedies of the Parties with respect to any breach of representation or warranty or non-performance, partial or total, of any covenant or agreement contained in this Agreement; provided, however, that nothing in this Section 15.10 shall prevent any Party from seeking injunctive or equitable relief in pursuit of its indemnification claims under Article 13 or this Article 15. Notwithstanding anything to the contrary in this Agreement, in the event of a conflict or inconsistency between this Section 15.10 and any other section or provision of this Agreement, this Section 15.10 shall govern and control.

15.11 Express Negligence Rule. THE INDEMNIFICATION AND ASSUMPTION PROVISIONS PROVIDED FOR IN THIS AGREEMENT HAVE BEEN EXPRESSLY NEGOTIATED IN EVERY DETAIL, ARE INTENDED TO BE GIVEN FULL AND LITERAL EFFECT, AND SHALL BE APPLICABLE WHETHER OR NOT THE LIABILITIES, OBLIGATIONS, CLAIMS, JUDGMENTS, LOSSES, COSTS, EXPENSES OR DAMAGES IN QUESTION ARISE OR AROSE SOLELY OR IN PART FROM THE GROSS, ACTIVE, PASSIVE OR CONCURRENT GROSS NEGLIGENCE, NEGLIGENCE, WILLFUL MISCONDUCT, STRICT LIABILITY, OR OTHER FAULT OF ANY INDEMNIFIED PARTY.

16.7 Entire Agreement. This Agreement and the documents and instruments and other agreements specifically referred to herein or delivered pursuant hereto, including the schedules hereto (a) constitute the entire agreement among the Parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter hereof and (b) are not intended to confer upon any other person or entity any rights or remedies hereunder except as Article 13 or Article 15 contemplates or except as otherwise expressly provided herein.

16.8 Binding Effect and Assignment. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective permitted successors and assigns; but neither this Agreement nor any of the rights, benefits or obligations hereunder shall be assigned, by operation of law or otherwise, by any Party hereto without the prior written consent of the other Parties; provided, that Copano may assign its right to receive the contribution of the Partnership Interests to any direct or indirect subsidiary or subsidiaries of Copano.

16.9 Severability. If any provision of the Agreement is rendered or declared illegal or unenforceable by reason of any existing or subsequently enacted legislation or by decree of a court of last resort, the Contributors and Copano shall promptly meet and negotiate substitute provisions for those rendered or declared illegal or unenforceable, but all of the remaining provisions of this Agreement shall remain in full force and effect and will not be affected or impaired in any way thereby.

16.10 Interpretation. The Parties agree that they have been represented by counsel during the negotiation and execution of this Agreement and, therefore waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the Party drafting such agreement or document.

The headings of the several Articles and Sections herein are inserted for convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement. The schedules referred to herein are attached hereto and incorporated herein by this reference, and unless the context expressly requires otherwise, such schedules are incorporated in the definition of “Agreement.”

16.12 Multiple Counterparts. This Agreement may be executed in one or more counterparts, and facsimile counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

16.13 No Waiver of Claims for Fraud. The liability of any Party under Article 13 or Article 15 shall be in addition to, and not exclusive of, any other liability that such Party may have at law or equity based on such Party’s fraudulent acts or omissions. None of the provisions set forth in this Agreement shall be deemed a waiver by any Party of any right or remedy which such Party may have at law or equity based on any other Party’s fraudulent acts or omissions, nor shall any such provisions limit, or be deemed to limit, (a) the amounts of recovery sought or awarded in any such claim for fraud, (b) the time period during which a claim for fraud may be brought, or (c) the recourse which any such Party may seek against another Party with respect to a claim for fraud; provided, however, that with respect to such rights and remedies at law or equity, the Parties further acknowledge and agree that none of the provisions of this Section

-61-

16.13 shall be deemed a waiver of any defenses which may be available in respect of actions or claims for fraud, including defenses of statutes of limitations or limitations of damages.

16.14 Anti-Dilution. Wherever in this Agreement there is a reference to a specific number of units of Copano of any class or series, or a price per unit or consideration received in respect of such unit, then, upon the occurrence of any subdivision, combination, or unit dividend or unit distribution of such class or series, the specific number of units or the price so referenced in this Agreement shall automatically be proportionately adjusted to reflect the effect on the outstanding units of such class or series by such subdivision, combination, dividend or distribution.

16.15 Partnership Split.

The Contributors may elect to effect the Partnership Split by delivering written notice to Copano no later than ten (10) days prior to the Closing Date, together with a detailed description of the assets to be transferred in connection therewith, but only in the event that Copano fails to provide the Contributors with a written notice that Copano has determined (in its sole discretion) that: (a) Contributors will fail to obtain prior to the Closing Date all Governmental Approvals or consents or approvals of any other Person that are required to be obtained or made in connection with the Partnership Split; or (b) Copano would be liable under the Transaction Documents after giving effect to the Partnership Split for liabilities and obligations (other than liabilities or obligations with respect to Transaction Taxes) in excess of the liabilities or obligations (other than liabilities or obligations with respect to Transaction Taxes) for which Copano would be liable under the Transaction Documents notwithstanding the Partnership Split. In the event that the Contributors properly elect to effect the Partnership Split, then the Parties shall use good faith efforts to agree to such amendments and modifications of the Transaction Documents as necessary to (i), after taking into account the Partnership Split, effect the provisions of the transactions contemplated under the Transaction Documents as of the date hereof and to realize the same economic benefits hereunder and (ii) provide an indemnity whereby after Closing the members and partners of the Contributors shall be liable for, and shall indemnify and hold Copano, and its respective Affiliates harmless from, any Transaction Taxes in excess of those Copano would be liable for notwithstanding the Partnership Split.

16.16 Amendment. This Agreement may not be amended except by an instrument in writing signed by or on behalf of all of the Parties.

16.17 Waiver. Any Party may (i) waive any inaccuracies in the representations and warranties of the other contained herein or in any document, certificate, or writing delivered pursuant hereto or (ii) waive compliance by the other Parties with any of the other Party’s agreements or fulfillment of any conditions to its own obligations contained herein. Any agreement on the part of a Party to any such waiver shall be valid only if set forth in an instrument in writing signed by or on behalf of such Party. No failure or delay by a Party in exercising any right, power, or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power, or privilege.

WHEREAS, the Escrow Agent is willing to serve as agent for the Escrow Parties on the terms and conditions set forth herein.

AGREEMENT:

NOW THEREFORE, in consideration of the foregoing and of the mutual covenants hereinafter set forth and for other good and valuable consideration the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Appointment. The Escrow Parties hereby appoint the Escrow Agent as their escrow agent for the purposes set forth herein, and the Escrow Agent hereby accepts such appointment under the terms and conditions set forth herein.

2. Escrow Deposit. Simultaneous with the execution and delivery of this Escrow Agreement, Party B is depositing with the Escrow Agent certificates no. , for shares, representing Class C Units of Copano Energy, L.L.C., issued in the

name of Party A as agent for the Contributors, along with executed stock powers duly executed in blank and signature guaranteed (together with any such replacement or additional certificated equity interests deposited with Escrow Agent in accordance with Section 4 below, the “Escrow Units”).

3. Disposition and Termination.

(a) From time to time, the Escrow Agent shall release and deliver the Escrow Units upon, and in accordance with the joint written instructions of the Escrow Parties, but only to the extent such releases and deliveries are specified in such instructions or order. The Escrow Agent shall receive and hold in trust in accordance with the terms hereunder such additional Escrow Units delivered in connection with the instructions or orders described in the foregoing sentence.

(b) Upon delivery and disbursement of the entirety of the balance of the Escrow Units by the Escrow Agent in accordance with Section 3.(a) above, this Escrow Agreement shall terminate, subject to the provisions of Section 6.

4. Escrow Agent. The Escrow Agent undertakes to perform only such duties as are expressly set forth herein and no duties shall be implied. The Escrow Agent shall have no liability under and no duty to inquire as to the provisions of any agreement other than this Escrow Agreement. The Escrow Agent may rely upon and shall not be liable for acting or refraining from acting upon any written notice, document, instruction or request furnished to it hereunder and believed by it to be genuine and to have been signed or presented by the proper party or parties. The Escrow Agent shall be under no duty to inquire into or investigate the validity, accuracy or content of any such document, notice, instruction or request. The Escrow Agent shall have no duty to solicit any payments which may be due it or the Escrow Deposit. The Escrow Agent shall not be liable for any action taken or omitted by it in good faith except to the extent that a final adjudication of a court of competent jurisdiction determines that the Escrow Agent’s gross negligence or willful misconduct was the primary cause of any loss to either of the Escrow Parties. The Escrow Agent may execute any of its powers and perform any of its duties hereunder directly or through agents or attorneys (and shall be liable only for the careful selection of any such agent or attorney) and may consult with counsel, accountants and other skilled persons to be selected and retained by it.

The Escrow Agent may interplead all of the assets held hereunder into a court of competent jurisdiction or may seek a declaratory judgment with respect to certain circumstances, and thereafter be fully relieved from any and all liability or obligation with respect to such interpleaded assets or any action or nonaction based on such declaratory judgment. The parties hereto other than the Escrow Agent agree to pursue any redress or recourse in connection with

-2-

any dispute without making the Escrow Agent a party to the same. Anything in this Escrow Agreement to the contrary notwithstanding, in no event shall the Escrow Agent be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Escrow Agent has been advised of the likelihood of such loss or damage and regardless of the form of action.

5. Succession. The Escrow Agent may resign and be discharged from its duties or obligations hereunder by giving thirty (30) days advance notice in writing of such resignation to the Escrow Parties specifying a date when such resignation shall take effect.

Any corporation or association into which the Escrow Agent may be merged or converted or with which it may be consolidated, or any corporation or association to which all or substantially all the escrow business of the Escrow Agent’s corporate trust line of business may be transferred, shall be the Escrow Agent under this Escrow Agreement without further act. Escrow Agent’s sole responsibility after such 30-day notice period expires shall be to hold the Escrow Units (without any obligation to reinvest the same) and to deliver the same to a designated substitute escrow agent, if any, or in accordance with the directions of a final order or judgment of a court of competent jurisdiction, at which time of delivery Escrow Agent’s obligations hereunder shall cease and terminate. If the Escrow Parties have failed to appoint a successor escrow agent prior to the expiration of thirty (30) days following receipt of the notice of resignation, the Escrow Agent may petition any court of competent jurisdiction for the appointment of a successor escrow agent or for other appropriate relief, and any such resulting appointment shall be binding upon all of the parties hereto.

6. Compensation and Reimbursement. The Escrow Parties agree jointly and severally to (i) pay the Escrow Agent upon execution of this Escrow Agreement and from time to time thereafter reasonable compensation for the services to be rendered hereunder, which unless otherwise agreed in writing shall be as described in Schedule 2 attached hereto, and (ii) pay or reimburse the Escrow Agent upon request for all expenses, disbursements and advances, including reasonable attorney’s fees and expenses, incurred or made by it in connection with the preparation, execution, performance, delivery, modification and termination of this Escrow Agreement.

7. Indemnity. The Escrow Parties shall jointly and severally indemnify, defend and save harmless the Escrow Agent and its directors, officers, agents and employees (the “indemnitees”) from and against any and all loss, liability or expense (including the fees and expenses of in house or outside counsel and experts and their staffs and all expense of document location, duplication and shipment) arising out of or in connection with (i) the Escrow Agent’s execution and performance of this Escrow Agreement, except in the case of any indemnitee to the extent that such loss, liability or expense is finally adjudicated to have been primarily caused by the gross negligence or willful misconduct of such indemnitee, or (ii) its following any instructions or other directions from Party A or Party B, except to the extent that its following any such instruction or direction is expressly forbidden by the terms hereof. The Escrow Parties hereto

-3-

acknowledge that the foregoing indemnities shall survive the resignation or removal of the Escrow Agent or the termination of this Escrow Agreement.

ARTICLE II

REGISTRATION RIGHTS

Section 2.01 Demand Registration.

(a) Requests for Registration. Subject to the limits set forth herein, the Contributors shall have the right by delivering a written notice to Copano (a “Demand Notice”) to require Copano to register, pursuant to the terms of this Agreement under and in accordance with the provisions of the Securities Act, the number of Registrable Securities requested to be so registered pursuant to the terms of this Agreement provided that the sale of such Registrable

Securities is reasonably expected to result in aggregate gross cash proceeds in excess of ten million dollars ($10,000,000) (a “Demand Registration”).

Following receipt of a Demand Notice for a Demand Registration, Copano shall use its reasonable commercial efforts to file a Shelf Registration Statement within 60 days of receipt of a Demand Notice, and, if such Shelf Registration Statement is not automatically effective upon filing, shall use its reasonable commercial efforts to cause such Registration Statement to be declared effective under the Securities Act as promptly as practicable after the filing thereof.

The Contributors shall be entitled to one Demand Registration; provided that no Demand Registration shall be exercised unless such Demand Registration is agreed to by the Holders of a majority of the outstanding Registrable Securities. No Demand Registration shall be deemed to have occurred for purposes of this Section 2.01 if the Shelf Registration Statement relating thereto (i) does not become effective, (ii) is not maintained effective for the period required pursuant to this Section 2.01(a) or (iii) the offering of the Registrable Securities pursuant to such Shelf Registration Statement is subject to a stop order, injunction or similar order or requirement of the Commission during such period. In the case of each of clauses (i), (ii) and (iii), the Contributors shall be entitled to an additional Demand Registration.

Any request made pursuant to this Section 2.01 will specify the amount of Registrable Securities to be registered and the intended methods of disposition thereof.

Copano shall be required to maintain the effectiveness of the Shelf Registration Statement with respect to any Demand Registration until all Registrable Securities included in such Shelf Registration Statement have actually been sold or there are no longer any Registrable Securities outstanding.

(b) Priority on Demand Registration. If any of the Registrable Securities registered pursuant to a Demand Registration are to be sold in an Underwritten Offering pursuant to Section 2.03, and the Managing Underwriter or underwriters advise the holders of such securities that in its or their view the total number or dollar amount of Registrable Securities proposed to be sold in such offering is such as to adversely affect the success of such offering (including, without limitation, securities proposed to be included by other holders of securities entitled to include securities in such offering pursuant to incidental or piggyback registration rights), then the number of Registrable Securities that in the opinion of such Managing Underwriter can be sold without adversely affecting such offering shall first include Registrable Securities requested to be included by the Contributors, pro rata based on the number of Registrable Securities requested to be included by each Contributor and, only if all such Registrable Securities are included, thereafter may include any other securities proposed to be included.

(c) Delay Rights. Notwithstanding anything to the contrary contained herein, Copano: (i) may delay its obligation to file any Shelf Registration Statement if (A) within 30 days of receipt of a Demand Notice, Copano notifies (the “Copano Delay Notice”) the Contributors of Copano’s intention of effecting a public offering within 60 days, provided, that prior to the receipt of such request, Copano has taken affirmative steps in contemplation of

such public offering, (B) Copano is pursuing an acquisition, merger, reorganization, disposition or other similar transaction and Copano determines in good faith that Copano’s ability to pursue or consummate such a transaction would be materially adversely affected by any required disclosure of such transaction in the Shelf Registration Statement, or (C) Copano has experienced some other material non-public event the disclosure of which at such time is not required by law or, in the good faith judgment of Copano, would materially adversely affect Copano, then, in each case, Copano may defer filing the Shelf Registration Statement for up to 60 days from receipt of the Copano Delay Notice; provided, however, that Copano shall not exercise its right to delay filing the Shelf Registration Statement more than once in any 12 month period; (ii) may, upon written notice to any Contributor whose Registrable Securities are included in the Shelf Registration Statement, suspend such Contributor’s use of any Prospectus which is a part of the Shelf Registration Statement (in which event the Contributor shall discontinue sales of the Registrable Securities pursuant to the Shelf Registration Statement) for up to 60 days from receipt of such notice if (A) Copano is pursuing an acquisition, merger, reorganization, disposition or other similar transaction and Copano determines in good faith that Copano’s ability to pursue or consummate such a transaction would be materially adversely affected by any required disclosure of such transaction in the Shelf Registration Statement or (B) Copano has experienced some other material non-public event the disclosure of which at such time is not required by law or, in the good faith judgment of Copano, would materially adversely affect Copano; provided, however, that Copano shall not exercise its right to suspend any Contributor’s use of any Prospectus more than twice in any 12-month period. Upon disclosure of such information or the termination of the condition described in this Section 2.01(c), Copano shall provide prompt notice to the Contributors whose Registrable Securities are included in the Shelf Registration Statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other actions to permit registered sales of Registrable Securities as contemplated in this Agreement.

Section 2.02 Piggyback Rights.

(a) Participation. If at any time Copano proposes to file (i) a prospectus supplement to an effective “shelf” registration statement, or (ii) a registration statement, other than a “shelf” registration statement, in either case, for the sale of Common Units in an Underwritten Offering for its own account and/or another Person, then as soon as practicable but not less than three (3) Business Days prior to the filing of (x) any preliminary prospectus supplement relating to such Underwritten Offering pursuant to Rule 424(b), (y) the prospectus supplement relating to such Underwritten Offering pursuant to Rule 424(b) (if no preliminary prospectus supplement is used) or (z) such registration statement as the case may be, then, Copano shall give notice of such proposed Underwritten Offering to the Holders and such notice shall offer the Holders the opportunity to include in such Underwritten Offering such number of Registrable Securities (the “Included Registrable Securities”) as each such Holder may request in writing; provided, however, that if Copano has been advised by the Managing Underwriter that the inclusion of Registrable Securities for sale for the benefit of the Holders will adversely affect the price, timing or distribution of the Common Units, then the amount of Registrable Securities to be offered for the accounts of Holders shall be determined based on the provisions of Section 2.02(b). Each Holder shall then have three (3) Business Days after receipt the notice to request inclusion of Registrable Securities in the Underwritten Offering, except that each Holder shall have one (1) Business Day after receipt of the notice to request inclusion of Registrable

Securities in the Underwritten Offering in the case of a “bought deal” or “overnight transaction”. If no request for inclusion from a Holder is received within the specified time, such Holder shall have no further right to participate in such Underwritten Offering. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of such Underwritten Offering, Copano shall determine for any reason not to undertake or to delay such Underwritten Offering, Copano may, at its election, give written notice of such determination to the Selling Holders and, (x) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering, and (y) in the case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such Selling Holder’s Registrable Securities in such offering by giving written notice to Copano of such withdrawal up to and including the time of pricing such offering.

(b) Priority of Piggyback Rights. If the Managing Underwriter or underwriters of any proposed Underwritten Offering of Common Units included in an Underwritten Offering involving Included Registrable Securities advises Copano that the total amount of Common Units that the Selling Holders and any other Persons intend to include in such offering exceeds the number that can be sold in such offering without being likely to have an adverse effect on the price, timing or distribution of the Common Units offered or the market for the Common Units, then the Common Units to be included in such Underwritten Offering shall include the number of Registrable Securities that such Managing Underwriter or Underwriters advises Copano can be sold without having such adverse effect, with such number to be allocated (i) first, to Copano; (ii) second, to Copano’s pre-IPO investors as provided in (A) the Stakeholders’ Agreement dated July 30, 2004, and (B) Article XIV of the Copano LLC Agreement; and (iii) third, pro rata among (A) those party to that certain Registration Rights Agreement dated December 29, 2005 by and among Copano and the purchasers named therein who have requested participation in such Underwritten Offering, (B) those party to that certain Registration Rights Agreement dated August 1, 2005, by and among Copano and the purchasers named therein who have requested participation in such Underwritten Offering, and (C) the Selling Holders party to this Agreement, based, for each such party and each Selling Holder, on the fraction derived by dividing (x) the number of Common Units proposed to be sold by such party or Selling Holder in such Underwritten Offering by (y) the aggregate number of Common Units proposed to be sold by all such parties and all Selling Holders in such Underwritten Offering pursuant to this clause (iii). As of the date of execution of this Agreement, there are no other Persons with Registration Rights other than as described in this Section 2.02(b).

Section 2.03 Underwritten Offering.

(a) Demand Registration. If a Selling Holder elects in a Demand Registration to dispose of Registrable Securities under the Shelf Registration Statement pursuant to an Underwritten Offering and reasonably anticipates gross proceeds of greater than twenty million dollars ($20,000,000) from such Underwritten Offering, Copano shall, at the request of such Selling Holder, enter into an underwriting agreement in customary form with the Managing Underwriter or underwriters, which shall include, among other provisions, indemnities to the effect and to the extent provided in Section 2.08, and shall take all such other reasonable actions

as are requested by the Managing Underwriter to expedite or facilitate the disposition of the Registrable Securities; provided, however, Copano management will not be required to participate in any roadshow or similar marketing effort on behalf of any Selling Holder.

(b) General Procedures. In connection with any Underwritten Offering under this Agreement, Copano shall be entitled to select the Managing Underwriter or underwriters. In connection with an Underwritten Offering under Section 2.03 hereof, each Selling Holder and Copano shall be obligated to enter into an underwriting agreement that contains such representations, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of securities. No Selling Holder may participate in such Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, Copano to and for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to its obligations. No Selling Holder shall be required to make any representations or warranties to or agreements with Copano or the underwriters other than representations, warranties or agreements regarding such Selling Holder and its ownership of the securities being registered on its behalf and its intended method of distribution and any other representation required by law. If any Selling Holder disapproves of the terms of an underwriting, such Selling Holder may elect to withdraw therefrom by notice to Copano and the Managing Underwriter; provided, however, that such withdrawal must be made prior to the time in the last sentence of Section 2.02(a) hereof to be effective. No such withdrawal or abandonment shall affect Copano’s obligation to pay Registration Expenses.

Section 2.04 Sale Procedures. In connection with its obligations contained in Section 2.01 and Section 2.03, Copano will, as expeditiously as possible:

(a) prepare and file with the Commission such amendments and supplements to the Registration Statement and the Prospectus used in connection therewith as may be necessary to keep the Shelf Registration Statement effective for the period set forth in Section 2.01(a) and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by the Shelf Registration Statement;

(b) furnish to each Selling Holder (i) as far in advance as reasonably practicable before filing the Shelf Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing the Shelf Registration Statement or such other registration statement or supplement or amendment thereto, and (ii) such number of copies of the Shelf

Registration Statement or such other registration statement and the Prospectus included therein and any supplements and amendments thereto as such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Shelf Registration Statement or other registration statement;

(c) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by the Shelf Registration Statement or any other registration statement contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as the Selling Holders or, in the case of an Underwritten Offering, the Managing Underwriter, shall reasonably request and keep such registration or qualification in effect for as long as the Shelf Registration Statement or other registration statement remains in effect; provided, however, that Copano will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action which would subject it to general service of process in any such jurisdiction where it is not then so subject;

(d) promptly notify each Selling Holder and each underwriter, at any time when a Prospectus relating thereto is required to be delivered under the Securities Act, of (i) the filing of the Shelf Registration Statement or any other registration statement contemplated by this Agreement or any Prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Shelf Registration Statement or any other registration statement or any post-effective amendment thereto, when the same has become effective (unless it is effective upon filing); and (ii) any written comments from the Commission with respect to any filing referred to in clause (i) and any written request by the Commission for amendments or supplements to the Shelf Registration Statement or any other registration statement or any Prospectus or prospectus supplement thereto;

(e) immediately notify each Selling Holder and each underwriter, at any time when a Prospectus relating thereto is required to be delivered under the Securities Act, of (i) the happening of any event as a result of which the Prospectus or prospectus supplement contained in the Shelf Registration Statement or any other registration statement contemplated by this Agreement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; (ii) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of the Shelf Registration Statement or any other registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose; or (iii) the receipt by Copano of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, Copano agrees to as promptly as practicable amend or supplement the Prospectus or prospectus supplement or take other appropriate action so that the Prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and to take such other action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(f) upon request and subject to appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with the

Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable Securities;

(g) in the case of an Underwritten Offering, upon request, (i) furnish opinions of counsel of Copano and a negative assurance letter of counsel to Copano and updates thereof covering the matters customarily covered in opinions and negative assurance letters requested in underwritten offerings and such other matters as may be reasonably requested by the underwriters, and (ii) obtain “cold comfort” letters and updates thereof from the independent certified public accountants of Copano (and, if necessary, any other independent certified public accountants of any subsidiary of Copano or of any business acquired by Copano for which financial statements and financial data are, or are required to be, included in the Shelf Registration Statement) who have certified the financial statements included in such Shelf Registration Statement, such letters to be in customary form and covering matters of the type customarily covered in “cold comfort” letters in connection with underwritten offerings and such other matters as may reasonably be requested by the underwriters;

(h) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

(i) make available to the appropriate representatives of the Managing Underwriter and Selling Holders access to such information and Copano personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided, however, that Copano need not disclose any information to any such representative unless and until such representative has entered into a confidentiality agreement with Copano;

(j) cause all such Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by Copano are then listed;

(k) use its commercially reasonable efforts to cause the Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of Copano to enable the Selling Holders to consummate the disposition of such Registrable Securities;

(l) provide a transfer agent and registrar for all Registrable Securities covered by such Shelf Registration Statement not later than the effective date of such Shelf Registration Statement; and

(m) enter into customary agreements and take such other actions as are reasonably requested by the Selling Holders or the underwriters, if any, in order to expedite or facilitate the disposition of such Registrable Securities.

Each Selling Holder, upon receipt of notice from Copano of the happening of any event of the kind described in subsection (e) of this Section 2.04, shall forthwith discontinue disposition of the Registrable Securities until such Selling Holder’s receipt of the copies of the

supplemented or amended prospectus contemplated by subsection (e) of this Section 2.04 or until it is advised in writing by Copano that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings incorporated by reference in the Prospectus, and, if so directed by Copano, such Selling Holder will, or will request the Managing Underwriter or underwriters, if any, to deliver to Copano (at Copano’s expense) all copies in their possession or control, other than permanent file copies then in such Selling Holder’s possession, of the Prospectus covering such Registrable Securities current at the time of receipt of such notice.

Section 2.05 Cooperation by Holders. Copano shall have no obligation to include in the Shelf Registration Statement units of a Holder or in a Underwritten Offering pursuant to Section 2.02 or Section 2.03 units of a Selling Holder who has failed to timely furnish such information that, in the opinion of counsel to Copano, is reasonably required in order for the Registration Statement or prospectus supplement, as applicable, to comply with the Securities Act.

Section 2.06 Restrictions on Public Sale by Holders of Registrable Securities. Each Holder of Registrable Securities who is included in a Registration Statement agrees not to effect any public sale or distribution of the Registrable Securities during the 30 calendar day period following completion of a public offering of equity securities by Copano except as specifically provided herein; provided, however, (i) that the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters on the officers or directors or any other unitholder of Copano on whom a restriction is imposed and (ii) the restrictions contained in this Section 2.06 shall not prevent a Holder from selling during such 30 calendar day period an aggregate of the lesser of a number of Common Units equal to (a) Copano’s average weekly trading volume over the prior four trading weeks on the Nasdaq National Market or other applicable exchange or (b) one percent of Copano’s outstanding Common Units measured as of the date of such sale and, provided further, that if a Holder has submitted a notice to request inclusion in an Underwritten Offering pursuant to Section 2.02(a) but is unable to sell any of such Common Units as a result of the priority provisions contained in Section 2.02(b), then such Holder shall not be subject to the restrictions contained in this Section 2.06.

Section 2.07 Expenses.

(a) Certain Definitions. “Registration Expenses” means all expenses incident to Copano’s performance under or compliance with this Agreement to effect the registration of Registrable Securities the Shelf Registration Statement pursuant to Section 2.01, an Underwritten Offering pursuant to Section 2.02 or Section 2.03, and the disposition of such securities, including, without limitation, all registration, filing, securities exchange listing and The Nasdaq National Market fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the National Association of Securities Dealers, Inc., transfer taxes and fees of transfer agents and registrars, all word processing, duplicating and printing expenses, the fees and disbursements of counsel and independent public accountants for Copano, including the expenses of any special audits or “cold comfort” letters required by or incident to such performance and compliance. Except as otherwise provided in Section 2.08 hereof, Copano shall not be responsible for legal fees incurred by Holders in

connection with the exercise of such Holders’ rights hereunder. In addition, Copano shall not be responsible for any “Selling Expenses,” which means all underwriting fees, discounts and selling commissions allocable to the sale of the Registrable Securities.

(b) Expenses. Copano will pay all reasonable Registration Expenses as determined in good faith, including, in the case of an Underwritten Offering, whether or not any sale is made pursuant to such Underwritten Offering. Each Selling Holder shall pay all Selling Expenses in connection with any sale of its Registrable Securities hereunder.

Section 2.08 Indemnification.

(a) By Copano. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, Copano will indemnify and hold harmless each Selling Holder thereunder, its directors, officers, employees and agents, and each underwriter, pursuant to the applicable underwriting agreement with such underwriter, of Registrable Securities thereunder and each Person, if any, who controls such Selling Holder or underwriter within the meaning of the Securities Act and the Exchange Act, against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder, its directors, officers, employees or agents, or any underwriter or controlling Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Shelf Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, 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 (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder, its directors, officers, employees or agents, or any underwriter or controlling Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings; provided, however, that Copano will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder, its directors, officers, employees or agents, or any underwriter or controlling Person in writing specifically for use in the Shelf Registration Statement or such other registration statement, or prospectus supplement, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder, its directors, officers, employees or agents, or any underwriter or controlling Person, and shall survive the transfer of such securities by such Selling Holder.

(b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless Copano, its directors, officers, employees and agents, and each Person, if any, who controls Copano within the meaning of the Securities Act or of the Exchange Act to the same extent as the foregoing indemnity from Copano to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Registration Statement or prospectus

supplement relating to the Registrable Securities, or any amendment or supplement thereto; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification.

(c) Notice. Promptly after receipt by an indemnified party hereunder 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 hereunder, notify the indemnifying party in writing 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 other than under this Section 2.08. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.08 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense and employ counsel reasonably acceptable to the indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnified party shall settle any action brought against it with respect to which it is entitled to indemnification hereunder without the consent of the indemnifying party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnifying party.

(d) Contribution. If the indemnification provided for in this Section 2.08 is held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each such 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 Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall a Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of the indemnifying party on the one hand and the indemnified party 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 has been made by, or relates to, information supplied by

such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to herein. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss which is the subject of this paragraph. 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 is not guilty of such fraudulent misrepresentation.

(e) Other Indemnification. The provisions of this Section 2.08 shall be in addition to any other rights to indemnification or contribution which an indemnified party may have pursuant to law, equity, contract or otherwise.

Section 2.09 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, Copano agrees to use its commercially reasonable efforts to:

(a) Make and keep public information regarding Copano available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times from and after the date hereof;

(b) File with the Commission in a timely manner all reports and other documents required of Copano under the Securities Act and the Exchange Act at all times from and after the date hereof; and

(c) So long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request a copy of the most recent annual or quarterly report of Copano, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration.

Section 2.10 Transfer or Assignment of Registration Rights. The rights to cause Copano to register Registrable Securities granted to the Contributors by Copano under this Article II may not be transferred or assigned by any Contributor unless (a) each such transferee or assignee is a partner (either general or limited), member or Affiliate of such Contributor, (b) Copano is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee or assignee and identifying the securities with respect to which such registration rights are being transferred or assigned, and (c) each such transferee or assignee assumes in writing responsibility for its portion of the obligations of such Contributor under this Agreement.

Section 2.11 Limitation on Subsequent Registration Rights. From and after the date hereof, Copano shall not, without the prior written consent of the Holders of a majority of the outstanding Registrable Securities, enter into any agreement with any current or future holder of

any securities of Copano that would allow such current or future holder to require Copano to include securities in any registration statement filed by Copano on a basis that is superior in any way to the piggyback rights granted to the Contributors hereunder.

ARTICLE III

MISCELLANEOUS

Section 3.06 Specific Performance. Damages in the event of breach of this Agreement by a party hereto may be difficult, if not impossible, to ascertain, and it is therefore agreed that each such Person, in addition to and without limiting any other remedy or right it may have, will have the right to an injunction or other equitable relief in any court of competent jurisdiction,

enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the parties hereto hereby waives any and all defenses it may have on the ground of lack of jurisdiction or competence of the court to grant such an injunction or other equitable relief. The existence of this right will not preclude any such Person from pursuing any other rights and remedies at law or in equity which such Person may have.

Section 3.07 Counterparts. This Agreement may be executed in any number of counterparts (including facsimile counterparts) and by different parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

Section 3.10 Severability of Provisions.

Section 3.11 Entire Agreement. This Agreement is intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein.

Section 3.12 Amendment. This Agreement may be amended only by means of a written amendment signed by Copano and the Holders of a majority of the then outstanding Registrable Securities; provided, however, that no such amendment shall materially and adversely affect the rights of any Holder hereunder without the consent of such Holder.

Section 3.13 No Presumption. If any claim is made by a party relating to any conflict, omission, or ambiguity in this Agreement, no presumption or burden of proof or persuasion shall be implied by virtue of the fact that this Agreement was prepared by or at the request of a particular party or its counsel.
