(b) Review and Audit by ECP Parties. The ECP Parties shall have 10 Business Days following receipt of the proposed ADA-ES Closing Date Contributed Capital Schedule to review such schedule and to accept or object to all or any portion of the capital contributions detailed therein. The ECP Parties, and their authorized representatives, shall be entitled, at their option, to conduct a review of the relevant books and records of ADA-ES that relate to the capital contributions detailed on the ADA-ES Closing Date Contributed Capital Schedule (and make copies thereof), including, without limitation, any relevant accounting work papers. ADA-ES shall make all such books and records reasonably available to the ECP Parties for review and shall otherwise provide all information, cooperation and assistance reasonably requested by the ECP Parties in connection with such review.

(c) Acceptance or Objection by ECP Parties. Unless the ECP Parties deliver written notice to ADA-ES on or prior to the 10th Business Day following the ECP Parties’ receipt of the ADA-ES Closing Date Contributed Capital Schedule, the ECP Parties shall be deemed to have accepted such ADA-ES Closing Date Contributed Capital Schedule. If the ECP Parties so notify ADA-ES of such an objection to the ADA-ES Closing Date Contributed Capital Schedule, the parties shall within 10 days following the date of such notice (the “Negotiation Period”) negotiate in good faith to resolve their differences. Any resolution by them as to any disputed amount shall be final, binding, conclusive and nonappealable, and judgment upon any such determination may be entered in any court of competent jurisdiction. Any such resolution, including through the use of a Neutral Auditor as hereinafter provided, shall be reflected on a mutually agreeable final ADA-ES Closing Date Capital Contribution Schedule.

(d) Resolution of Disputes by Neutral Auditor. If, at the conclusion of the Negotiation Period, the parties have not resolved their disputes, then all amounts remaining in dispute shall, at the election of either Party, be submitted to an auditor who shall be selected by the mutual agreement of the parties (“Neutral Auditor”). The Neutral Auditor shall be engaged no later than 10 days after an election by a Party to submit its objections to the Neutral Auditor, and each party agrees to execute, if requested

by the Neutral Auditor, a reasonable engagement letter. The Neutral Auditor shall be a nationally recognized independent registered accounting firm that is not rendering (and during the preceding two-year period has not rendered) audit services to either ADA-ES or the ECP Parties or any of their respective Affiliates. If the parties are unable to agree on such Neutral Auditor, then the respective accounting firms of ADA-ES and the ECP Parties shall choose the Neutral Auditor. All fees and expenses of the Neutral Auditor shall be borne equally by ADA-ES and the ECP Parties. The Neutral Auditor shall act as an arbitrator to determine, based solely on the presentations by ADA-ES and the ECP Parties, and not by independent review, only those issues still in dispute. The Neutral Auditor’s determination shall be made within 30 days of its engagement, shall be set forth in a written statement delivered to ADA-ES and the ECP Parties and shall be final, binding, conclusive and nonappealable. Such determination will be reflected in the Final ADA-ES Contributed Capital Schedule.

(e) Immediately upon the acceptance or other determination of the Final ADA-ES Capital Contribution Schedule, ADA-ES shall (i) assign and convey to the Red River Project Company all Tangible Personal Property reflected on such Final ADA-ES Contributed Capital schedule, and (ii) be deemed to have made a capital contribution to the Development Company in an amount equal to the total expenditures set forth on such ADA-ES Closing Date Contributed Capital Schedule (the “ADA-ES Adjustment Amount”) pursuant to and in accordance with Section 3.3(c)(i) of the Operating Agreement.

4.26 Accuracy of Statements and Information. Neither this Agreement nor any schedule, exhibit, statement, list, document, certificate or other information furnished or to be furnished by or on behalf of ADA-ES to the ECP Parties or any representative or Affiliate of the ECP Parties in connection with this Agreement or any of the Transactions contemplated hereby contains or will contain any untrue statement of a material fact or omits or will omit to state a material fact necessary to make the statements contained herein or therein, in light of the circumstances in which they are made, not misleading.

9.2 Method of Asserting Claims. All claims for indemnification by any Indemnified Party under Section 9.1 (Indemnification) will be asserted and resolved as follows:

(a) Third Party Claims. In the event any claim or demand in respect of which an Indemnified Party might seek indemnity under Section 9.1 (Indemnification) is asserted against or sought to be collected from such Indemnified Party by a Person other than an ECP Indemnified Party or an ADA-ES Indemnified Party (“Third Party Claim”), the Indemnified Party shall deliver a Claim Notice with reasonable promptness to the Indemnifying Party; provided, however, that the failure of the Indemnified Party to give notice shall not relieve the Indemnifying Party of its obligations under this Article IX except to the extent that the Indemnifying Party shall have been materially prejudiced thereby. The Indemnifying Party will notify the Indemnified Party as soon as practicable within the Dispute Period whether the Indemnifying Party disputes its liability to the Indemnified Party under Section 9.1 (Indemnification) and whether the Indemnifying Party desires, at its sole cost and expense, to defend the Indemnified Party against such Third Party Claim.

(i) If the Indemnifying Party notifies the Indemnified Party within the Dispute Period that the Indemnifying Party desires to defend the Indemnified Party with respect to the Third Party Claim pursuant to Section 9.2(a), then the Indemnifying Party will have the right to defend, at the sole cost and expense of the Indemnifying Party, such Third Party Claim by all appropriate proceedings, which proceedings will be diligently prosecuted by the Indemnifying Party to a final conclusion or will be settled at the discretion of the Indemnifying Party (but only with the consent of the Indemnified Party, such consent not to be unreasonably withheld). The Indemnifying Party will have full control of such defense and proceedings, including (except as provided in the immediately preceding sentence) any settlement thereof; provided, however, that (x) the Indemnifying Party’s counsel is reasonably satisfactory to the Indemnified Party, (y) the Indemnifying Party shall thereafter consult with the Indemnified Party upon the Indemnified Party’s reasonable request for such consultation from time to time with respect to such claim, suit, action or proceeding and (z) the Indemnified Party may, at the sole cost and expense of the Indemnified Party, at any time prior to the Indemnifying Party’s delivery of the notice referred to in the first sentence of this Section 9.2(a)(i), file any motion, answer or other pleadings or take any other action that the Indemnified Party reasonably believes to be necessary or appropriate to protect its interests. If requested by the Indemnifying Party, the Indemnified Party will, at the sole cost and expense of the Indemnifying Party, cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim that the Indemnifying Party elects to contest. The Indemnified Party may retain separate counsel to represent it in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 9.2(a)(i), and the Indemnified Party will bear its own costs and expenses with respect to such separate counsel except as provided in the preceding sentence and except that the Indemnifying Party will pay the costs and expenses of such separate counsel if (A) in the Indemnified Party’s good faith judgment, it is advisable, based on advice of counsel, for the Indemnified Party to be represented by separate counsel because a conflict or potential conflict exists between the Indemnifying Party and Indemnified Party which makes representation of both parties inappropriate under applicable standards of professional conduct or (B) the

named parties to such Third Party Claim include both the Indemnifying Party and the Indemnified Party and the Indemnified Party determines in good faith, based on advice of counsel, that defenses are available to it that are unavailable to the Indemnifying Party. Notwithstanding the foregoing, the Indemnified Party may retain or take over the control of the defense or settlement of any Third Party Claim the defense of which the Indemnified Party has elected to control if the Indemnified Party irrevocably waives its right to indemnity under Section 9.1 (Indemnification) with respect to such Third Party Claim.

(ii) The Indemnified Party will have the right to defend, at the sole cost and expense of the Indemnifying Party, by all appropriate proceedings, which proceedings will be prosecuted by the Indemnified Party to a final conclusion or will be settled at the discretion of the Indemnified Party (i) any Third Party Claim with respect to any Existing Action or Proceeding and (ii) any Third Party Claim for which the Indemnifying Party fails to notify the Indemnified Party within the Dispute Period that the Indemnifying Party desires to defend such Third Party Claim pursuant to Section 9.2(a), or for which the Indemnifying Party gives such notice but fails to prosecute diligently or settle such Third Party Claim. The Indemnified Party will have full control of such defense and proceedings, including any settlement thereof; provided, however, that if requested by the Indemnified Party, the Indemnifying Party will, at the sole cost and expense of the Indemnifying Party, cooperate with the Indemnified Party and its counsel in contesting any Third Party Claim which the Indemnified Party is contesting, or, if appropriate and related to the Third Party Claim in question, in making any counterclaim against the Person asserting the Third Party Claim, or any cross-complaint against any Person (other than the Indemnified Party or any of its Affiliates). Notwithstanding the foregoing provisions of this Section 9.2(a)(ii), except with respect to any Existing Action or Proceeding, if the Indemnifying Party has notified the Indemnified Party within the Dispute Period that the Indemnifying Party disputes its liability hereunder to the Indemnified Party with respect to such Third Party Claim and if such dispute is resolved in favor of the Indemnifying Party in the manner provided in clause (iii) below, the Indemnifying Party will not be required to bear the costs and expenses of the Indemnified Party’s defense pursuant to this Section 9.2(a)(ii) or of the Indemnifying Party’s participation therein at the Indemnified Party’s request, and the Indemnified Party will reimburse the Indemnifying Party in full for all reasonable third party costs and expenses incurred by the Indemnifying Party in connection with such litigation. The Indemnifying Party may retain separate counsel to represent it in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section 9.2(a)(ii), and the Indemnifying Party will bear its own costs and expenses with respect to such participation.

(iii) If the Indemnifying Party notifies the Indemnified Party that it does not dispute its liability to the Indemnified Party with respect to the Third Party Claim under Section 9.1 (Indemnification) or fails to notify the Indemnified Party within the Dispute Period whether the Indemnifying Party disputes its liability to the Indemnified Party with respect to such Third Party Claim, the Loss arising from such Third Party Claim will be conclusively deemed a liability of the Indemnifying Party under Section 9.1 (Indemnification) and the Indemnifying Party shall pay the amount of such Loss to the Indemnified Party on demand following the final determination thereof.

If the Indemnifying Party has timely disputed its liability with respect to such claim, the Indemnifying Party and the Indemnified Party will proceed in good faith to negotiate a resolution of such dispute, and if not resolved through negotiations within the Resolution Period, such dispute shall be resolved by litigation in a court of competent jurisdiction.

(b) Claims Other Than Third Party Claims. In the event any Indemnified Party should have a claim under Section 9.1 (Indemnification) against any Indemnifying Party that does not involve a Third Party Claim, the Indemnified Party shall deliver an Indemnity Notice with reasonable promptness to the Indemnifying Party. If the Indemnifying Party notifies the Indemnified Party that it does not dispute the claim described in such Indemnity Notice or fails to notify the Indemnified Party within the Dispute Period whether the Indemnifying Party disputes the claim described in such Indemnity Notice, the Loss arising from the claim specified in such Indemnity Notice will be conclusively deemed a liability of the Indemnifying Party under Section 9.1 (Indemnification) and the Indemnifying Party shall pay the amount of such Loss to the Indemnified Party on demand following the final determination thereof, and no later objection by the Indemnifying Party shall be permitted. If the Indemnifying Party agrees that it has an indemnification obligation but objects that it is obligated to pay only a lesser amount, the Indemnifying Party shall promptly pay to the Indemnified Party the lesser amount, without prejudice to the Indemnified Party’s claim for the difference. If the Indemnifying Party has timely disputed all of its liability with respect to such claim, the Indemnifying Party and the Indemnified Party will proceed in good faith to negotiate a resolution of such dispute, and if not resolved through negotiations within the Resolution Period, such dispute shall be resolved by litigation in a court of competent jurisdiction.

9.3 Exclusive Remedy. Except (a) as set forth in Section 11.8 (Specific Performance), (b) claims for fraud or deceit, (c) any circumstances giving rise to a Party’s right to terminate this Agreement, and (d) any rights or remedies provided in each of the other Operative Documents (including, without limitation, the Operating Agreement), the indemnification provisions of Article IX (Indemnification) shall be the sole and exclusive remedy of each Party (including Indemnified Parties) for any breach of any Party’s representations, warranties covenants or agreements contained in this Agreement. In furtherance of the foregoing, each Party hereby waives, to the fullest extent permitted under applicable law, any and all rights, claims and causes of action it or any of its Affiliates may have against another Party hereunder or under applicable law with respect to the claims described in Sections 9.2(a) (Method of Asserting Claims) and (b) (Same) above.

Accordingly, each of the Parties agrees that the other Party shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof in any action instituted in any court of the United States or any state thereof having jurisdiction over the Parties and the matter in addition to any other remedy to which it may be entitled, at law or in equity.

11.9 No Third Party Beneficiary. The terms and provisions of this Agreement are intended solely for the benefit of each Party hereto and their respective successors or permitted assigns, and it is not the intention of the Parties to confer third-party beneficiary rights upon any other Person other than any Person entitled to indemnity under Section 1.7 (Excluded Liabilities) and Article IX (Indemnification).

11.10 No Assignment; Binding Effect. Neither this Agreement nor any right, interest or obligation hereunder may be assigned by any Party hereto without the prior written consent of the other Party hereto and any attempt to do so will be void, except (i) for assignments and transfers by operation of Law and (ii) a Party may assign any or all of its rights, interests and obligations hereunder to a wholly-owned subsidiary, provided that any such subsidiary agrees in writing to be bound by all of the terms, conditions and provisions contained herein, but no such assignment referred to in clause (ii) shall relieve such Party of its obligations hereunder. Subject to the preceding sentence, this Agreement is binding upon, inures to the benefit of and is enforceable by the Parties hereto and their respective successors and assigns.

11.11 Headings. The headings used in this Agreement have been inserted for convenience of reference only and do not define or limit the provisions hereof.

11.12 Invalid Provisions.

11.13 Mutual Drafting. The Parties are sophisticated and have been represented by attorneys throughout the transactions contemplated hereby who have carefully negotiated the provisions hereof. As a consequence, the Parties do not intend that the presumptions of laws or rules relating to the interpretation of contracts against the drafter of any particular clause should be applied to this Agreement, the Operative Agreements, the Transactions or any agreement or instrument executed in connection herewith, and therefore waive their effects.

11.14 Governing Law. This Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware, without giving effect to the conflicts of laws principles (whether of the State of Delaware or otherwise) that would result in the application of the laws of any other jurisdiction.
