acknowledges and agrees that it shall remain the primary obligor under this Agreement, and as such, the Purchaser further acknowledges and agrees that any claims for indemnity pursuant to Section 6.02 of this Agreement shall be satisfied first by the Purchaser, and if the Purchaser does not have sufficient assets to satisfy claims for indemnity pursuant to Section 6.02 of this Agreement, then the transferee shall be liable to Copano for up to the balance due on any such claims pursuant to Section 6.02 of this Agreement (based on the number of Series A Preferred Units Transferred relative to the total number of Purchased Units).

Copano agrees to indemnify the Purchaser and its Representatives (collectively, “Purchaser Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages or expenses of any kind or nature whatsoever (including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them), whether or not involving a Third Party Claim, as a result of, arising out of, or in any way related to (i) the failure of any of the representations or warranties made by Copano contained herein to be true and correct in all material respects as of the date hereof (except with respect to any provisions including the word “material” or words of similar import, with respect to which such representations and warranties must have been true and correct) or (ii) the breach of any of the covenants of Copano contained herein; provided, that in the case of the immediately preceding clause (i), such claim for indemnification relating to a breach of any representation or warranty is made prior to the expiration of such representation or warranty; provided, however, that for purposes of determining when an indemnification claim has been made, the date upon which a Purchaser Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to Copano shall constitute the date upon which such claim has been made; provided, further, that the liability of Copano shall not be greater in amount than the Purchase Price.

Section 6.02 Indemnification by the Purchaser. The Purchaser agrees to indemnify Copano and its Representatives (collectively, “Copano Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs,

losses, liabilities, damages or expenses of any kind or nature whatsoever (including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them), whether or not involving a Third Party Claim, as a result of, arising out of, or in any way related to (i) the failure of any of the representations or warranties made by the Purchaser contained herein to be true and correct in all material respects as of the date hereof or (ii) the breach of any of the covenants of the Purchaser contained herein; provided, that in the case of the immediately preceding clause (i), such claim for indemnification relating to a breach of any representation or warranty is made prior to the expiration of such representation or warranty; provided, however, that for purposes of determining when an indemnification claim has been made, the date upon which a Copano Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to the Purchaser shall constitute the date upon which such claim has been made; provided, further, that the liability of the Purchaser (and its Affiliates, if the Purchaser Transfers a portion or all of the Purchased Units to an Affiliate as permitted by Section 5.02) shall not be greater in amount than the Purchase Price.

Section 6.03 Indemnification Procedure.

(a) A claim for indemnification for any matter not involving a Third Party Claim may be asserted by notice to the party from whom indemnification is sought; provided, however, that failure to so notify the indemnifying party shall not preclude the indemnified party from any indemnification that it may claim in accordance with this Article VI, except as otherwise provided in Sections 6.01 and 6.02.

(b) Promptly after any Copano Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement (each, a “Third Party Claim”), the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such Third Party Claim but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such Third Party Claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle such Third Party Claim, it shall promptly, and in no event later than five (5) days, notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and/or the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the

Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has, within ten (10) Business Days of when the Indemnified Party provides written notice of a Third Party Claim, failed (y) to assume the defense or settlement of such Third Party Claim and employ counsel and (z) notify the Indemnified Party of such assumption, or (B) 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 in addition 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 settlement or legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not contain any admission of wrongdoing by, the Indemnified Party.

Section 6.04 Tax Matters. All indemnification payments under this Article VI shall be adjustments to the Purchase Price, except as otherwise required by applicable Law.

ARTICLE VII

MISCELLANEOUS

Section 7.01 Fees and Expenses. Copano shall pay out of the proceeds received from the consummation of the transactions contemplated by this Agreement: (i) a transaction fee of 3% of the Purchase Price to the Purchaser or its designee on the date hereof and (ii) the reasonable out-of-pocket fees and expenses incurred by the Purchaser in connection the transactions contemplated by the Basic Documents, including without limitation, legal, accounting, advisory and other reasonable out-of-pocket fees and expenses; provided, that the expenses of the Purchaser paid out of such proceeds shall not exceed $1,000,000 in the aggregate.

Section 7.02 Interpretation. Article, Section and Schedule references in this Agreement are references to the corresponding Article, Section and Schedule to this Agreement, unless otherwise specified. All Schedules to this Agreement are hereby incorporated and made a part hereof as if set forth in full herein and are an integral part of this Agreement. All references to instruments, documents, Contracts and agreements are references to such instruments, documents, Contracts and agreements as the same may be amended, supplemented and otherwise modified from time to time, unless otherwise specified. The word “including” shall mean “including but not limited to” and shall not be construed to limit any general statement that it follows to the specific or similar items or matters immediately following it. Whenever Copano has an obligation under the Basic Documents, the expense of complying with that obligation shall be an expense of Copano unless otherwise specified. Any reference in this Agreement to $ shall mean U.S. dollars. Whenever any determination, consent or approval is to be made or

given by the Purchaser, such action shall be in the Purchaser’s sole discretion, unless otherwise specified in this Agreement. If any provision in the Basic Documents is held to be illegal, invalid, not binding or unenforceable, (i) such provision shall be fully severable and the Basic Documents shall be construed and enforced as if such illegal, invalid, not binding or unenforceable provision had never comprised a part of the Basic Documents, and the remaining provisions shall remain in full force and effect and (ii) the parties hereto shall negotiate in good faith to modify the Basic Documents so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. When calculating the period of time before which, within which or following which any act is to be done or step taken pursuant to the Basic Documents, the date that is the reference date in calculating such period shall be excluded. If the last day of such period is a non-Business Day, the period in question shall end on the next succeeding Business Day. Any words imparting the singular number only shall include the plural and vice versa. The words such as “herein,” “hereinafter,” “hereof” and “hereunder” refer to this Agreement as a whole and not merely to a subdivision in which such words appear unless the context otherwise requires. The provision of a Table of Contents, the division of this Agreement into Articles, Sections and other subdivisions and the insertion of headings are for convenience of reference only and shall not affect or be utilized in construing or interpreting this Agreement.

Section 7.03 Survival of Provisions. The representations and warranties set forth in Sections 3.01, 3.02, 3.04, 3.06, 3.08, 3.20, 3.22, 3.24, 4.01, 4.02, 4.04 and 4.05 hereunder shall survive the execution and delivery of this Agreement indefinitely, the representations and warranties set forth in Sections 3.16 and 3.21 shall survive for a period of three (3) years following the date hereof regardless of any investigation made by or on behalf of Copano or the Purchaser, and the other representations and warranties set forth herein shall survive for a period of eighteen (18) months following the date hereof regardless of any investigation made by or on behalf of Copano or the Purchaser. The covenants made in this Agreement or any other Basic Document shall survive the Closing and remain operative and in full force and effect regardless of acceptance of any of the Purchased Units and payment therefor and repayment, conversion or repurchase thereof. Regardless of any purported general termination of this Agreement, the provisions of Article VI and all indemnification rights and obligations of Copano and the Purchaser thereunder, and this Article VII shall remain operative and in full force and effect as between Copano and the Purchaser, unless Copano and the Purchaser execute a writing that expressly (with specific references to the applicable Section or subsection of this Agreement) terminates such rights and obligations as between Copano and the Purchaser.

Section 7.04 No Waiver; Modifications in Writing.

(a) Delay. No failure or delay on the part of any party in exercising any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies provided for herein are cumulative and are not exclusive of any remedies that may be available to a party at law or in equity or otherwise.

(b) Specific Waiver. Except as otherwise provided herein, no amendment, waiver, consent, modification or termination of any provision of this Agreement or any other Basic

Document (except in the case of the Copano LLC Agreement for amendments adopted pursuant to Section 11.1(c) thereof) shall be effective unless signed by each of the parties hereto or thereto affected by such amendment, waiver, consent, modification or termination. Any amendment, supplement or modification of or to any provision of this Agreement or any other Basic Document, any waiver of any provision of this Agreement or any other Basic Document and any consent to any departure by Copano from the terms of any provision of this Agreement or any other Basic Document shall be effective only in the specific instance and for the specific purpose for which made or given. Except where notice is specifically required by this Agreement, no notice to or demand on Copano in any case shall entitle Copano to any other or further notice or demand in similar or other circumstances. Any investigation by or on behalf of any party shall not be deemed to constitute a waiver by the party taking such action of compliance with any representation, warranty, covenant or agreement contained herein.

Section 7.05 Binding Effect; Assignment.

(a) Binding Effect. This Agreement shall be binding upon Copano, the Purchaser and their respective successors and permitted assigns. Except as expressly provided in this Agreement, this Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and permitted assigns.

(b) Assignment of Rights. The Purchaser’s rights and obligations hereunder (including the right to seek indemnification) may be transferred or assigned in whole or in part by the Purchaser to any Affiliate of the Purchaser without the consent of Copano. Upon any such permitted transfer or assignment, references in this Agreement to the Purchaser (as they apply to the transferor or assignor, as the case may be) shall thereafter apply to such transferee or assignee of the Purchaser unless the context otherwise requires. Without the written consent of Copano, which consent shall not be unreasonably withheld, no portion of the rights and obligations of the Purchaser under this Agreement may be assigned or transferred by the Purchaser or such a transferee of Purchased Units to a Person that is not an Affiliate of the Purchaser. No portion of the rights and obligations of Copano under this Agreement may be transferred or assigned without the prior written consent of the Purchaser, which consent shall not be unreasonably withheld.

Section 7.06 Non-Disclosure.

(a) The Purchaser agrees to abide by its obligations under the Non-Disclosure Agreement.

(b) The Copano Entities and any of their respective Representatives shall disclose any information naming the Purchaser or any of its Affiliates (other than simply naming the Purchaser and its Affiliates as a party to certain of the Basic Documents and describing the transactions contemplated by the Basic Documents) in any filing with the Commission, NASDAQ or any Governmental Authority or other public disclosure, only after providing the Purchaser a reasonable opportunity to review and comment on such disclosure (with such comments being incorporated or reflected, to the extent reasonable, in any such disclosure); provided, however, that nothing in this Section 7.06 shall delay any required filing with the

Commission, NASDAQ or any Governmental Authority or other public disclosure or otherwise hinder the Copano Entities’ or their Representatives’ ability to timely comply with all Laws or rules and regulations of the Commission, NASDAQ or other Governmental Authority.

Section 7.07 Communications.

Section 7.08 Removal of Legend.

(a) The Purchaser may request Copano to remove the legend set forth in Section 4.05(e) from the certificates evidencing the Purchased Units by submitting to Copano such certificates, together with an opinion of counsel to the effect that such legend is no longer required under the Securities Act or applicable state laws as the case may be, as Copano may request; provided, that, no opinion of counsel shall be required if the Purchaser is effecting a sale of Purchased Units pursuant to Rule 144 under the Securities Act (and the Purchaser delivers a Rule 144 Representation Letter to Copano) or the Conversion Common Units have been registered under the Securities Act pursuant to an effective registration statement. Copano shall cooperate with the Purchaser to effect removal of such legend. Subject to the provisions of the Copano LLC Agreement, the legend described in Section 4.05(e) shall be removed and Copano shall issue a certificate without such legend to the holder of Purchased Units upon which it is stamped, if, unless otherwise required by state securities Laws, (i) such Purchased Units are sold pursuant to an effective registration statement, (ii) in connection with a sale, assignment or other transfer, such holder provides Copano with an opinion of a law firm reasonably acceptable to Copano, in a generally acceptable form, to the effect that such sale, assignment or transfer of such Purchased Units may be made without registration under the applicable requirements of the Securities Act, or (iii) in connection with a sale, assignment of or other transfer of such Purchased Units, such holder provides Copano with a representation letter that such Purchased Units will be sold, assigned or transferred pursuant to Rule 144 under the Securities Act. Copano shall bear all direct costs and expenses associated with the removal of a legend pursuant to this Section 7.08; provided, that the Purchaser shall be responsible for all legal fees and expenses of counsel incurred by the Purchaser with respect to matters addressed in this Section 7.08.

(b) Certificates evidencing Conversion Units shall not contain any legend (including the legend set forth in Section 4.05(e)), (i) while a registration statement covering the resale of such security is effective under the Securities Act and the Purchaser delivers to Copano a representation letter agreeing that such Conversion Units will be sold under such effective registration statement, or (ii) following any sale of such Conversion Units pursuant to Rule 144, or (iii) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission).

Section 7.09 Entire Agreement. This Agreement, the other Basic Documents and the other agreements and documents referred to herein are 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 and therein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein or the other Basic Documents with respect to the rights granted by Copano or any of its Affiliates or the Purchaser or any of their Affiliates set forth herein or therein. This Agreement, the other Basic Documents and the other agreements and documents referred to herein or therein supersede all prior agreements and understandings between the parties with respect to such subject matter.

Section 7.10 Governing Law; Submission to Jurisdiction. This Agreement, and all claims or causes of action (whether in contract or tort) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement), will be construed in accordance with and governed by the laws of the State of Delaware without regard to principles of conflicts of laws. Any action against any party relating to the foregoing shall be brought in any federal or state court of competent jurisdiction located within the State of Delaware, and the parties hereto hereby irrevocably submit to the non-exclusive jurisdiction of any federal or state court located within the State of Delaware over any such action.

THE PARTIES TO THIS AGREEMENT EACH HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

Section 7.12 Execution in Counterparts.
