2.3 No Violation. The execution, delivery and performance by Seller of its obligations under this Agreement, and the performance by each Subsidiary Transferor of this Agreement, in each case including without limitation the sale of the Acquired Interests to the Purchaser, do not, and will not, (a) violate any Governmental Rule to which Seller or any Subsidiary Transferor is subject or the Organization Documents of Seller or any Subsidiary Transferor, (b) conflict with, result in a breach of, constitute a default under, result in the acceleration of, create in any party the right to accelerate, terminate, modify or cancel or require any notice under any agreement, contract, lease, license, instrument or other arrangement to which Seller or any Subsidiary Transferor is a party or by which Seller or any Subsidiary Transferor is bound or (c) conflict with, result in a breach of, constitute a default under, result in the acceleration of, create in any party the right to accelerate, terminate, modify or cancel or require any notice under any Material Contract, except, in the case of this clause (c), as would not reasonably be expected to be material in the context of the Wind Project or otherwise prevent or materially impair or delay the consummation of the transactions contemplated by this Agreement.

(b) Access, Information and Documents. Seller will give to Purchaser and to Purchaser’s counsel, accountants and other representatives reasonable access during normal business hours to all material Books and Records and the Wind Project (subject to all applicable safety and insurance requirements and any limitations on Seller’s rights to, or right to provide others with, access) and will furnish to Purchaser all such documents and copies of documents and all information, including operational reports, with respect to the affairs of the Project Company, the Seller Affiliates, and the Wind Project as Purchaser may reasonably request subject to any confidentially obligations imposed on Seller by any unaffiliated counterparties to such contracts and agreements.

No Updated Disclosure Schedule delivered pursuant to this Section 4.1(c) shall be deemed to cure any breach of any representation or warranty unless Purchaser specifically agrees thereto in writing or, as provided in and subject to Article 5, consummates the Closing under this Agreement after receipt of such written notification, nor shall any such Updated Disclosure Schedule be considered to constitute or give rise to a waiver by Purchaser of any condition set forth in this Agreement, unless Purchaser specifically agrees thereto in writing or consummates the Closing under this Agreement after receipt of such written notification.

(d) Further Assurances. Each of the parties hereto shall use commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to consummate the transactions contemplated hereby as soon as practicable.

(d) Allocation of Purchase Price.

(i)

The Purchase Price shall be allocated between the Acquired Interests based on the percentages set forth on Schedule 4.2(d).

(ii)

For the portion of the Purchase Price that is allocated to the interest in the Project Company pursuant to Section 4.2(d)(i), Purchaser shall deliver to Seller, within 60 days of the Closing, a statement (the “U.S. Allocation Statement”) allocating such portion (plus any applicable liabilities) among the Project Company’s assets in a manner consistent with sections 755 and 1060 of the Code. The U.S. Allocation Statement shall be considered final and binding on Purchaser and Seller, unless Seller determines in good faith that the U.S. Allocation Statement is unreasonable and provides Purchaser with notice of such determination within fifteen days of the delivery of the U.S. Allocation Statement, in which case Seller and Purchaser shall negotiate in good faith to resolve their differences. If any differences cannot be resolved within fifteen days of such notice, Purchaser and Seller shall jointly retain an accounting firm that is nationally recognized in the United States (the “Accounting Referee”) to determine whether the U.S. Allocation Statement is reasonable and, if not, to make only those adjustments as are required to cause the U.S. Allocation Statement to reflect a reasonable allocation of the relevant portion of the Purchase Price under sections 755 and 1060 of the Code.

(iii)

Each of Seller and Purchaser agrees to (x) be bound by the U.S. Allocation Statement and (y) act, and cause its Affiliates to act, in accordance with the U.S. Allocation Statement in the preparation, filing and audit of any U.S. federal income Tax Return (including filing Form 8594 with any U.S. federal income Tax Return that it may be required to file for the taxable year that includes the date of the Closing).

(iv)

If an adjustment is made with respect to the Purchase Price pursuant to Section 1.3 or otherwise, the U.S. Allocation Statement shall be adjusted in accordance with Section 1060 of the Code and as mutually agreed by Seller and Purchaser. In the event that an agreement is not reached within 20 days after the proposal by Purchaser of an adjustment to the U.S. Allocation Statement pursuant to this Section 4.2(d)(iv), any disputed items shall be resolved in the manner, and based on the standard, described in Section 4.2(d)(ii). Seller and Purchaser agree to file, and to cause their respective Affiliates to file, any additional information return required to be filed pursuant to Section 1060 of the Code and to treat the U.S. Allocation Statement as adjusted in the manner described in this Section 4.2(d)(iv).

(v)

Seller, Purchaser and their respective Affiliates shall use the Canadian dollar equivalent on the Closing Date of the portion of the Purchase Price so allocated to each Acquired Interest for all Canadian income Tax purposes and shall not file any Canadian income Tax Returns inconsistent therewith.

Indemnified Party for any Claim for breach of any representation or warranty unless and until the aggregate amount of all Claims for which it would, in the absence of this provision, be liable exceeds the Basket Amount, and in such event the Indemnified Party will be liable for the amount of all Claims, including the Basket Amount; provided that the foregoing limitation shall not apply in the case of actual fraud by the Indemnifying Party.

(b) Maximum Limit on Claims.

(i)

Limitation on Seller’s Liability. Seller’s maximum aggregate liability for Claims for breaches of representations and warranties under this Agreement is limited to Seller’s Maximum Liability set forth in Part VI of Appendix B; provided that the Seller’s Maximum Liability will not apply to any Claim based on (A) actual fraud or (B) any breach of the representations and warranties set forth in Sections 2.1, 2.2, 2.3, 2.5, 2.6, 2.9, and 2.11.

(a) Right of Reimbursement. The amount of Losses payable under Section 6.1 by an Indemnifying Party shall be net of any (i) amounts recovered by the Indemnified Party under applicable insurance policies or from any other Person responsible therefor, and (ii) any Tax benefit actually realized by the Indemnified Party arising from the incurrence or payment of any such Losses. If the Indemnified Party receives any amounts under applicable insurance policies, or from any other Person responsible for any Losses subsequent to an indemnification payment by the Indemnifying Party and such amounts would result in a duplicative recovery, then such Indemnified Party shall promptly reimburse the Indemnifying Party for any payment made or expense incurred by such Indemnifying Party in connection with providing such indemnification payment up to the amount received by the Indemnified Party, net of any expenses incurred by such Indemnified Party in collecting such amount.

(b) Other Refund Obligations. In addition to the obligations set forth in Section 6.3(a), the applicable Indemnified Party shall be obligated to reimburse or refund to the

Indemnifying Party for payments made by it to such Indemnified Party under this Article 6 as set forth in Part VI of Appendix B.

6.4 Right to Control Proceedings for Third Party Claims.

(a) If a third party shall notify any party with respect to any matter that may give rise to a Claim (a “Third Party Claim”), the Indemnified Party must give notice to the Indemnifying Party of the Third Party Claim (a “Third Party Claim Notice”) within twenty (20) Business Days after it becomes aware of the existence of the Third Party Claim and that it may constitute a Third Party Claim. The Indemnified Party’s failure to give a Third Party Claim Notice in compliance with this Section 6.4(a) of any Third Party Claim which may give rise to a right of indemnification hereunder shall not relieve the Indemnifying Party of any liability which it may have to the Indemnified Party unless, and solely to the extent that, the failure to give such notice materially and adversely prejudiced the Indemnifying Party.

(b) The Indemnifying Party shall have the right to participate in, or by giving written notice to the Indemnified Party, to assume control of the defense of any Third Party Claim with the Indemnifying Party’s own counsel, in each case at the Indemnifying Party’s own cost and expense (provided that prior to assuming control of such defense, the Indemnifying Party must acknowledge its indemnity obligations under this Article 6), and the Indemnified Party shall cooperate in good faith in such defense. The Indemnified Party shall have the right, at its own cost and expense, to participate in the defense of any Third Party Claim with separate counsel selected by it, subject to the Indemnifying Party’s right to control the defense thereof; provided that in such event the Indemnifying Party shall pay the fees and expenses of such separate counsel (i) incurred by the Indemnified Party prior to the date the Indemnifying Party assumes control of the defense of the Third Party Claim, (ii) if such Third Party Claim would reasonably be expected to be materially detrimental to the business, reputation or future prospects of any Indemnified Party or (iii) if representation of both the Indemnifying Party and the Indemnified Party by the same counsel would create a conflict of interest. If the Indemnifying Party (i) fails to promptly notify the Indemnified Party in writing of its election to defend or fails to acknowledge its indemnity obligations under this Article 6 as provided in this Agreement, (ii) elects not to defend (or compromise at its sole cost and expense) such Third Party Claim, (iii) has elected to defend such Third Party Claim but fails to promptly and diligently pursue the defense such Third Party Claim, (iv) otherwise breaches any of its obligations under this Article 6 or (v) as set forth on Schedule 6.4(b) hereto, or if the Third Party Claim is reasonably expected by the Indemnified Party to result in a payment obligation on the Indemnified Party in an amount that exceeds the maximum indemnification then available to the Indemnified Party pursuant to this Article 6, then the Indemnifying Party shall not be entitled to assume or maintain control of the defense of such Third Party Claim and the Indemnified Party may (by written notice to the Indemnifying Party) assume control of such defense (in which case the Indemnifying Party shall pay the fees and expenses of counsel retained by the Indemnified Party) and/or compromise such Third Party Claim and seek indemnification for any and all Losses based upon, arising from or relating to such Third Party Claim. The Parties shall cooperate with each other in all reasonable respects in connection with the defense of any Third Party Claim.

(c) Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not enter into any settlement of any Third Party Claim without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed), except as provided in this Section 6.4(c). If a firm offer is made to settle a Third Party Claim that (i) does not (A) result in any liability or create any financial or other obligation on the part of the Indemnified Party and (B) result in the loss of any right or benefit on the part of any Indemnified Party, (ii) does not impose injunctive or other equitable relief against any Indemnified Party, and (iii) provides, in customary form, for the unconditional release of each Indemnified Party from all liabilities and obligations in connection with such Third Party Claim, and the Indemnifying Party desires to accept and agree to such firm offer, then the Indemnifying Party shall give written notice to that effect to the Indemnified Party. If the Indemnified Party fails to consent to such firm offer within ten days after its receipt of such notice, the Indemnified Party may continue to contest or defend such Third Party Claim and in such event, the maximum liability of the Indemnifying Party as to such Third Party Claim shall not exceed the amount of such settlement offer. If the Indemnified Party fails to consent to such firm offer within such 20 day period and also fails to assume defense of such Third Party Claim, the Indemnifying Party may settle the Third Party Claim upon the terms set forth in such firm offer to settle such Third Party Claim. If the Indemnified Party has assumed the defense pursuant to Section 6.4(b), it may settle the Third Party Claim; provided that if the settlement is made without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed), the Indemnifying Party shall have no indemnity obligation pursuant to this Article 6 with respect to such Third Party Claim.

6.5 Mitigation; Treatment of Indemnification.

(a) An Indemnified Party shall use commercially reasonable efforts to mitigate all Losses relating to a Claim for which indemnification is sought under this Article 6.

(b) All indemnification payments under this Article 6 shall be deemed adjustments to the Purchase Price.

6.6 Exclusive Remedy. Each of Seller and Purchaser acknowledges and agrees that, should the Closing occur, and excluding liability for actual fraud, the foregoing indemnification provisions of this Article 6 and the provisions of Section 7.15 shall be the sole and exclusive remedy of Seller and Purchaser with respect to any misrepresentation, breach of warranty, covenant or other agreement (other than any Purchase Price Adjustment set forth in Part I of Appendix B) or other claim arising out of this Agreement or the transactions contemplated hereby. Without limiting the generality of the foregoing, effective as of the Closing each of Purchaser and Seller covenants to the other party that in respect of any matters under or contemplated in this Agreement, it will not make any Claim whatsoever against any Affiliate of the other party or the directors, officers, managers, shareholders, member, controlling persons, employees and agents of any of the foregoing, in each case in their capacities as such, and its rights in respect of any such Claim for breach of any provision of this Agreement are limited solely to such rights as it may have against Seller or Purchaser, as the case may be, under this Agreement.

(b) Any and all claims, counterclaims, demands, causes of action, disputes, controversies, and other matters in question arising out of or relating to this Agreement, or the alleged breach hereof, or in any way relating to the subject matter of this Agreement or the relationship between the Parties created by this Agreement (hereafter, a “Dispute”) shall be finally resolved by binding arbitration administered by the American Arbitration Association (“AAA”) under the AAA Commercial Arbitration Rules , including the Procedures for Large, Complex Commercial Disputes (the “Rules”) then in force to the extent such Rules are not inconsistent with the provisions of this Agreement. The party commencing arbitration shall

deliver to the other party a written notice of intent to arbitrate (a “Demand”) in accordance with Rule R-4. The arbitration shall be governed by the Federal Arbitration Act, 9 U.S.C. §§1 et seq.

(i)

Selection of Arbitrators. Disputes shall be resolved by a panel of three independent and impartial arbitrators, (the “Arbitrators”). The party initiating the arbitration shall appoint an arbitrator in its Demand; the responding party shall appoint an arbitrator in its answering statement, which is due 30 days after receipt of the Demand. If any party fails or refuses to timely nominate an arbitrator within the time permitted, such arbitrator shall be appointed by the AAA from individuals with significant experience in renewable energy projects from its Large, Complex Commercial Case Panel. Within 30 days of the appointment of the second arbitrator, the two party-appointed arbitrators shall appoint the third arbitrator, who shall act as the chair of the arbitration panel. If the two party-appointed arbitrators fail or refuse to appoint the third arbitrator within such 30-day period, the third arbitrator shall be appointed by the AAA from individuals with significant experience in renewable energy projects from its Large, Complex Commercial Case Panel in accordance with Rule R-12. The Arbitrators, acting by majority vote, shall resolve all Disputes.

(ii)

To the fullest extent permitted by law, the arbitration proceedings and award shall be maintained in confidence by the parties.

Each party further agrees to accept service of process out of any of the before mentioned courts in any such dispute by registered or certified mail addressed to the party at the address set forth in Part VII of Appendix B.

(iv)

Conduct of the Arbitration. The arbitration shall be conducted in accordance with the Rules and in a manner that effectuates the Parties’ intent that Disputes be resolved expeditiously and with minimal expense. The Arbitrators shall endeavor to commence the arbitration hearing within 180 days of the third arbitrator’s appointment.

(v)

Interim Relief. Either party may apply to the Arbitrators seeking injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. Either party also may, without waiving any remedy under this agreement, seek from any court having jurisdiction any interim or provisional relief that is necessary to protect the rights or property of that party, pending the establishment of the arbitral tribunal (or pending the Arbitrators’ determination of the merits of the controversy).

(vi)

Discovery. The Arbitrators, upon a showing of good cause, may require and facilitate such limited discovery as it shall determine is appropriate in the circumstances, taking into account the needs of the parties, the burden on the parties, and the desirability of making discovery limited, expeditious, and cost-effective. The Arbitrators shall issue orders to protect the confidentiality of proprietary information, trade secrets and other sensitive information disclosed in discovery.

(vii)

Arbitration Award. The Arbitrators shall endeavor to issue a reasoned, written award within 30 days of the conclusion of the arbitration hearing.

The limitations of Section 7.14 shall apply to any award by the Arbitrators.

Except as otherwise expressly provided, the rules of construction set forth in Appendix A-2 shall apply to this Agreement. The parties agree that any rule of law or any legal decision that would require interpretation of any claimed ambiguities in this Agreement against the party that drafted it has no application and is expressly waived.

7.8 No Other Beneficiaries. This Agreement is being made and entered into solely for the benefit of Purchaser and Seller, and neither Purchaser nor Seller intends hereby to create any rights in favor of any other person as a third party beneficiary of this Agreement or otherwise.

7.9 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the jurisdiction specified in Part VII of Appendix B.

7.10 Schedules. References to a Schedule shall include any disclosure expressly set forth on the face of any other Schedule even if not specifically cross-referenced to such other Schedule to the extent that the relevance of such matter is reasonably apparent on the face thereof. The fact that any item of information is contained in a disclosure schedule shall not be construed as an admission of liability under any Governmental Rule, or to mean that such information is material. Such information shall not be used as the basis for interpreting the term “material”, “materially,” “Material Impact,” or any similar qualification in this Agreement.

7.11 Limitation of Representation and Warranties. EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES SET FORTH IN ARTICLE 2, SELLER HAS NOT MADE AND SELLER EXPRESSLY DISCLAIMS ANY REPRESENTATIONS OR WARRANTIES, OF ANY KIND OR NATURE, WRITTEN OR ORAL, STATUTORY, EXPRESS OR IMPLIED, WITH RESPECT TO THE ACQUIRED INTERESTS, SELLER OR SELLER AFFILIATES, THE PROJECT COMPANY, THE WIND PROJECT OR THE SUBJECT MATTER OF THIS AGREEMENT. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, EXCEPT AS EXPRESSLY PROVIDED IN ARTICLE 2, THE ACQUIRED INTERESTS ARE BEING CONVEYED “AS IS” IN ALL RESPECTS, AND SELLER EXPRESSLY DISCLAIMS ANY REPRESENTATION OR WARRANTY OF FITNESS, MERCHANTABILITY OR SUITABILITY FOR A PARTICULAR PURPOSE.

7.12 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but which together shall constitute one and the same instrument. A facsimile or electronically imaged version of this Agreement may be executed by one or more parties hereto and an executed copy of this Agreement may be delivered by one or more parties hereto by facsimile or “PDF” electronic mail pursuant to which the signature of or on behalf of such party can be seen, and such execution and delivery shall be considered valid, binding and effective for all purposes.

7.13 Severability. If any provision of this Agreement or any other agreement entered into pursuant hereto is contrary to, prohibited by or deemed invalid under applicable law or regulation, such provision shall be inapplicable and deemed omitted to the extent so contrary, prohibited or invalid, but the remainder hereof shall not be invalidated thereby and shall be given full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement 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 be consummated as originally contemplated to the fullest extent possible.

7.14 Limit on Damages. Each party hereto acknowledges and agrees that neither party shall be liable to the other party for any punitive damages (except to the extent paid to a third party in respect of a Third Party Claim) or damages that were not reasonably foreseeable.
