Buyer acknowledges that, insofar as the release set out in Section 6.4(a) extends to Persons other than Seller, Seller holds the benefit of the release in trust for those other Persons.

(b) General Limitations on Claims. No Person shall be entitled to make any claim for breach of any representation or warranty under Section 6.2(a) in respect of, and Buyer acknowledges the representations and warranties contained in this Agreement are given subject to, all matters fairly disclosed in the disclosures set forth on the Seller Disclosure Schedules and, to the extent provided in Section 7.5, disclosures made by Seller in accordance with Section 7.5; provided, however, that any matter so disclosed shall relate only to those representations and warranties to which the applicability of such information is reasonably apparent.

(c) Limitations on the Extent of Claims. Notwithstanding any other provision of this Agreement, no liability shall attach to Seller in respect of any claim for breach of any representation or warranty to the extent that such claim is recovered by Buyer from any third party.

(d) Other Limitations. Notwithstanding anything to the contrary contained herein but subject to Section 6.7(d) and (e) below, none of the Buyer Indemnified Persons shall be entitled to assert any right to indemnification under Section 6.2(a) until the aggregate amount of all Losses actually suffered by the Buyer Indemnified Persons exceeds one percent (1%) of the Purchase Price (the “Deductible Amount”) (after which point Seller shall be obligated to indemnify the Buyer Indemnified Persons from and against any and all Losses including the Deductible Amount); provided, however, that the foregoing limitations shall not apply to any breach of any Fundamental Representations. Notwithstanding anything in this Agreement to the contrary, in no event shall Seller ever be required to indemnify Buyer or any of the other Buyer Indemnified Persons under Section 6.2 for Losses exceeding, in the aggregate, an amount equal to fifteen percent (15%) of the Purchase Price (the “Cap Amount”); provided, however that amounts payable for breaches of Fundamental Representations shall not be subject to nor included in the calculation of the Cap Amount. If a breach by Seller of a representation or warranty has occurred under this Agreement, then solely for purposes of calculating the amount of any Losses in respect of such breach which are subject to indemnification under this Article 6, such Losses shall be determined without regard to any limitation or qualification as to materiality, Material Adverse Effect, dollar thresholds or similar language in such representation or warranty.

(e) Waiver of Breach. Notwithstanding the foregoing, and without limiting Section 7.5, an Indemnified Party shall have no right of indemnification against an Indemnifying Party with respect to a breach of a representation or warranty as of the Closing if, as of the date hereof, the Indemnified Party had actual knowledge of the misrepresentation or breach of warranty; provided, however, that the foregoing shall not constitute a waiver of any other rights hereunder with respect to such misrepresentation or breach.

(a) Mitigation. In no event shall either Party be liable hereunder for any special, punitive, exemplary, incidental or consequential damages or lost profits, whether based on contract, tort, strict liability, other Law or otherwise and whether or not arising from the other Party’s sole, joint or concurrent negligence, strict liability or other fault for any matter relating to this Agreement and the transactions contemplated hereby; provided, however, that amounts expressly specified herein shall not be deemed to be limited or waived by the foregoing. The Indemnified Party shall take commercially reasonable steps to mitigate all Losses upon becoming aware of any event which could reasonably be expected to give rise thereto, including commercially reasonable steps to avail itself of any defenses, limitations, rights of contribution, Actions against third Persons and other rights at Law or equity, and will provide such evidence and documentation of the nature and extent of the Losses as may be reasonably requested by the Indemnifying Party. The Indemnified Party’s commercially reasonable steps include the reasonable expenditure of money, at the Indemnifying Party’s sole expense, to mitigate or otherwise reduce or eliminate any Losses for which indemnification would otherwise be due under this Article 6. In the event of any obligation or liability of an Indemnifying Party under this Article 6 that does not arise from a Third Party Claim, upon receipt of written notice, the Indemnifying Party shall be permitted, at its option, to take action to cure any matter giving rise to a right of indemnification if the Loss has not yet been fully incurred for a period not to exceed thirty (30) days after such notice. The Indemnifying Party’s election not to exercise its right to cure shall not reduce or eliminate the Indemnified Party’s obligation to mitigate damages or the Indemnifying Party’s obligation to indemnify the Indemnified Party for any Losses.

(b) Limitation on Losses. The Losses giving rise to any indemnification obligation hereunder shall be limited to the actual loss suffered by the Indemnified Party (i.e., reduced by any insurance proceeds or other payment or recoupment actually received, realized or retained by the Indemnified Party as a result of the events giving rise to an Action for indemnification), net of the actual reduction in income Tax liability of the Indemnified Party (or the Affiliated Group of which it is a member) occasioned by such loss or damage, but including any costs, fees or expenses reasonably incurred by the Indemnified Party. Upon the request of the Indemnifying Party, the Indemnified Party shall provide the Indemnifying Party with information sufficient to allow the Indemnifying Party to calculate the amount of the indemnity payment in accordance with this Section 6.5. If and to the extent that an Indemnifying Party has made an indemnification payment to an Indemnified Party pursuant to this Section 6.5 with respect to a Loss and the Indemnified Party has been and will be fully indemnified and compensated for such Loss from a Party other than the Indemnifying Party, the Indemnified Party shall pay to the Indemnifying Party: (i) the amount of any payment irrevocably received by the Indemnified Party or any Affiliate thereof from a party other than the Indemnifying Party with respect to such Loss, and (ii) the amount of any insurance proceeds or other cash receipts actually received by the Indemnified Party or any of the Indemnified Party’s Affiliates with respect to such Loss or the matter that gave rise to the Loss, such amounts described in subparagraphs (i) and (ii) above shall be net of reasonable attorneys’ fees and other collection costs related to such payments and recoveries, and no right of subrogation shall accrue to any insurer hereunder. In no event shall an Indemnified Party be required to pay over, under this Section 6.5, an amount in the aggregate in excess of the indemnity payment previously payable to the Indemnifying Party with respect to the Losses in issue.

(c) No Liability Under Material Contracts or Third Party Work Product. Notwithstanding anything express or implied herein to the contrary, in no event shall Seller be liable hereunder in contract, tort for or otherwise with respect to any work product (whether written or otherwise) of third party advisors or professionals such as the Wind Resource Consultant (“Third Party Work Product”) including, for the avoidance of doubt, the Wind Resource Reports, it being acknowledged by Buyer that any Action with respect to any such documents or agreements shall be made solely under the terms of the Contract pursuant to which such Third Party Work Product was provided. Without limiting Seller’s liability hereunder for any breach of representation expressly made hereunder, including representations regarding the existence, breaches of, or effect of this Agreement or the transactions contemplated hereby upon any agreements, nothing herein shall be deemed to give rise to liability in contract, tort or otherwise under any Material Contract.

(i) Following the Closing Date, the provisions of this Article 6 shall be the sole and exclusive remedies of the Parties for any breach of the representations or warranties contained in this Agreement with respect to the transactions consummated on the Closing Date.

(ii) Neither this Section 6.5 nor any other provision of this Agreement shall be deemed to waive or limit in any way any representations, warranties, covenants, or agreements of any Person under any Project Document, or any rights or remedies available to any Subject Company under any Project Document or of any other party thereto.

(e) Other Agreements. Nothing herein shall be deemed to limit the liability of either Party or its Affiliates under any other Transaction Document, except to the extent that such liability is expressly stated to be solely a guaranty or other assumption of liability under this Agreement.

(a) Third Party Claims. If any third party shall notify an Indemnified Party with respect to any matter (a “Third Party Claim”) that may give rise to an Action for indemnification against an Indemnifying Party under this Article 6, and if such Indemnified Party intends to seek indemnity with respect thereto hereunder, then such Indemnified Party shall promptly notify the Indemnifying Party of such Third Party Claim in writing; provided, however, that subject to the time limitations specified in Section 6.1, a failure to give timely notice as provided in the foregoing will affect the rights or obligations of a Party hereunder only to the extent that, as a result of such failure, the Party entitled to receive such notice was actually prejudiced as a result of such failure.

(b) Right to Assume Defense. The Indemnifying Party shall have thirty (30) days after receipt of such notice (or such longer period as may be reasonably agreed by the Indemnified Party) to elect to undertake, conduct and control the defense or settlement of the Third Party Claim (with counsel of its choice and at its own expense), provided that the Indemnifying Party confirms in writing its obligation to indemnify and hold harmless the Indemnified Party for the full amount of any Losses resulting from the Third Party Claim; provided, however, that the Indemnifying Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Party, which consent shall not to be unreasonably withheld or delayed, unless the judgment or proposed settlement (i) involves only the payment of money damages solely by the Indemnifying Party, and (ii) does not impose an Order or other equitable relief upon the Indemnified Party or otherwise prejudice the Indemnified Party as to similar Actions in the future. The Indemnifying Party shall keep the Indemnified Party fully informed as to all material developments in connection with the Third Party Claim.

(c) Right to Defend. So long as the Indemnifying Party, at the Indemnifying Party’s cost and expense, (1) has undertaken the defense of, and assumed full responsibility for, all indemnified Liabilities with respect to such Third Party Claim; (2) is reasonably contesting such Third Party Claim in good faith, by appropriate Actions; and (3) has taken such action (including the posting of a bond, deposit, or other security) as may be necessary to prevent any Action to foreclose a lien against or attachment of the property of the Indemnified Person for payment of such Third Party Claim, the Indemnified Person shall not pay any claim arising from or settle any such Action. If the Indemnifying Party fails, within thirty (30) days after the receipt of the Indemnified Person’s notice of an Action for indemnity hereunder (or such longer period as may be reasonably agreed by the Indemnified Party), to notify the Indemnified Person that the Indemnifying Party elects to undertake the defense thereof and assume full responsibility for all indemnified Liabilities with respect thereto, or fails, at any time after having given such notice, to contest such Action in good faith or to prevent any Action to foreclose a lien against or attachment of the Indemnified Person’s property as contemplated above, the Indemnified Person shall have the right to contest, settle, or compromise such Action and the Indemnified Person shall not thereby waive any right to indemnity for such Action under this Agreement.

(d) No Settlement. Except as set forth in Section 6.6(c) above, in no event will the Indemnified Party consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed.

6.7 Coordination of Indemnification Under the 60% MIPSA and this Agreement. The following provisions shall apply effective upon the Closing:

(a) In no case shall Buyer be entitled to duplicate recovery of any monetary Loss under the provisions of the 60% MIPSA and this Agreement, collectively.

(b) Subject to the other provisions of this Section 6.7, Losses in respect of any claim subject to indemnification under the 60% MIPSA shall include all such Losses actually incurred by Buyer and shall not be prorated or otherwise reduced as a result of Buyer having held a lesser Percentage Interest in Sponsor prior to Closing under this Agreement. However, Losses in respect of any claim under this Agreement for which there is no corresponding claim under the 60% MIPSA (whether the survival period expired or such claim is otherwise not available) shall be limited to Buyer’s Purchased Interest acquired under this Agreement and shall not include any Losses in respect of the Percentage Interests acquired under the 60% MIPSA.

(c) The survival periods set forth in the 60% MIPSA for claims made under the 60% MIPSA shall not be extended by this Agreement. The survival periods set forth herein for claims under this Agreement shall commence on the Closing Date.

(d) The Deductible Amount, if any, applicable to claims under the 60% MIPSA or this Agreement shall be calculated on an aggregate basis as the applicable percentage (e.g., 1%) of Buyer’s Aggregate Consideration and no claim shall be made under either the 60% MIPSA or this Agreement unless all such claims shall, in the aggregate, exceed such Deductible Amount (it being understood that if the applicable survival period has expired under the 60% MIPSA but not under this Agreement, the Deductible Amount shall be equal to 1% of the Purchase Price paid by Buyer hereunder). “Buyer’s Aggregate Consideration” shall be the sum of the Buyer Project Funding amounts paid by Buyer, the Initial Capital Contributions paid by Buyer, the Additional Sponsor Purchase Paid by Buyer, the amount of $3 million paid by Buyer for an additional 1.25% interest in Sponsor on December 10, 2012, and the Purchase Price paid by Buyer hereunder.

(e) The Cap Amount, if any, applicable to claims under the 60% MIPSA and this Agreement shall be calculated on an aggregate basis as the applicable percentage (e.g., 15%) of Buyer’s Aggregate Consideration (it being understood that if the applicable survival period has expired under the 60% MIPSA but not under this Agreement, the Cap Amount shall be reduced to 15% of the Purchase Price paid by Buyer hereunder).

(a) The Parties shall take all commercially reasonable steps necessary or desirable and proceed diligently and in good faith to satisfy the conditions to the obligations contained in this Agreement and shall not take or fail to take any action that would reasonably be expected to result in the nonfulfillment of any such condition.

(b) Without limiting the foregoing, Seller shall consult with and coordinate with Buyer to file or cause to be filed, as soon as practicable after the date hereof, the application required to be filed with FERC for an Order from FERC under the FPA authorizing the transfer of the Purchased Interests contemplated hereby. Seller shall consult with and cooperate with Buyer as to the contents of such application, and shall respond promptly to any requests for additional information made by FERC.

(c) Additionally, without limiting the foregoing, each Party shall use reasonable best efforts to cause all representations and warranties of such Party to be true and correct as of the Closing, and shall not take or fail to take any action that would reasonably be expected to result in any such representations and warranties of such Party to fail to be true and correct as of the Closing in any material respect.

7.2 Transfer Taxes. Buyer and Seller will each be responsible for 50% of all sales, use, transfer, real property transfer, recording, stock transfer and other similar Taxes and fees, if any, arising out of or in connection with the sale of the Purchased Interests and the consummation of the transactions contemplated by this Agreement. Buyer and Seller will indemnify, defend and hold harmless the other Party, its Affiliates, and the Subject Companies with respect to such Taxes for which it is responsible. Buyer and Seller shall cooperate in the filing of all necessary documentation and Tax Returns with respect to such Taxes.

(a) At any time or from time to time after the Closing, each Party will, upon the reasonable request of the other Party, execute and deliver any further instruments or documents, and exercise commercially reasonable efforts to take such further actions as may reasonably be required, to fulfill and implement the transactions contemplated by this Agreement.

(b) Without limiting the foregoing, upon or, as necessary, promptly following the Closing Date, Seller and Buyer shall take such actions as necessary under any other agreements by or between the Parties or any of their Affiliates to reflect the increase in Buyer’s Percentage Interest in Sponsor from 60.00% to 100.00%.

7.4 Securities Law Covenant. Buyer will not transfer or otherwise dispose of any of the Purchased Interests, or any interest in the Purchased Interests, in such manner as to cause Seller or its Affiliates to be in violation of the registration requirements of the Securities Act, or applicable federal or state securities or blue sky Laws.

(a) Prior to the Closing, each Party will advise the other in writing with respect to any matter arising after the date of this Agreement relevant to the Closing of which that Party obtains Knowledge and that, if existing or occurring on or prior to the date of this Agreement, would have been required to be disclosed to the other Party in order to make the representations and warranties in Article III or IV, as applicable, true and correct. Seller and Buyer shall also provide each other with notice of any event or circumstance related to the transactions contemplated by this Agreement having a Material Adverse Effect on a Subject Company promptly upon having Knowledge of such event or circumstance.

(b) Seller will from time to time prior to the Closing, promptly disclose to Buyer in writing any matter relevant to the Closing arising after the date of this Agreement, which if existing as of the date of this Agreement, would have been required to be disclosed to Buyer or described in the representations in Article III in order to make any representation or warranty set forth in this Agreement true and correct as of such date; provided, however, that no such disclosure shall be permitted to reflect matters constituting or arising out of a breach by Seller of any covenant under this Agreement, the ECCA or any other Transaction Document. In the event that Seller provides written notice to Buyer prior to the Closing that such matters, individually or in the aggregate, constitute a Material Adverse Effect but Buyer elects to effectuate the Closing, any breach of any representation or warranty made by Seller which would exist absent such disclosure will be deemed cured with respect to the Closing and all rights of Buyer to indemnification hereunder with respect to such breach shall be deemed waived with respect to the Closing. Any such disclosure shall otherwise be disregarded in determining, and shall not be deemed to be waived with respect to, the fulfillment and satisfaction of any conditions specified herein to any obligations of Buyer, and shall not be deemed to cure any breach of a representation or otherwise affect any other rights of Buyer hereunder; provided, however, that notwithstanding the foregoing, the Seller Disclosure Schedules shall be deemed updated for all purposes, and no breach or non-satisfaction of conditions shall be deemed to exist, for amendments or changes to Project Documents or other matters consented to by Buyer or expressly permitted under this Agreement.

7.6 Announcements. The Parties shall use commercially reasonable efforts to first consult with and consider any feedback from the other Party prior to issuing any press release relating to the transactions contemplated by this Agreement.

7.7 Project Completion Items. Buyer acknowledges that Seller has completed the matters described in Sections 7.15(a)-(d) and items 1, 2, and 4-6 on Schedule 7.15(e) of the 60% MIPSA. The Parties agree that, upon Closing, item 3 on Schedule 7.15(e) of the 60% MIPSA shall be deleted in its entirety (it being acknowledged by the Parties that the matters described in item 3 shall be addressed in the OMA Amendments and the TSA Amendments).

8.1 Tax Periods Ending on or Before the Closing Date. In accordance with the Sponsor LLC Agreement, Sponsor will prepare and file all Tax Returns for Sponsor for Tax periods ending on or prior to the Closing Date.

8.2 Tax Periods Beginning Before and Ending After the Closing Date. In accordance with the Sponsor LLC Agreement, Sponsor will prepare and file all Tax Returns for Sponsor for Tax periods that begin before the Closing Date and end after the Closing Date. Taxes that relate to any Taxable period that includes (but does not end on) the Closing Date shall be apportioned between the Pre-Closing Tax Period and the Post-Closing Tax Period as follows: (a) in the case of Taxes other than sales and use and withholding

Taxes, on a per diem basis, and (b) in the case of sales and use and withholding Taxes, as determined from the books and records of Sponsor as though the Taxable year of Sponsor terminated at the close of business on the Closing Date. For purposes of this Section 8.2, (x) “Post-Closing Tax Period” means any Taxable period beginning after the Closing Date and, with respect to any Taxable period beginning before and ending after the Closing Date, the portion of such Taxable period beginning after the Closing Date, and (y) “Pre-Closing Tax Period” means any Taxable period ending on or prior to the Closing Date and, with respect to any Taxable period beginning before and ending after the Closing Date, the portion of such Taxable period ending on the Closing Date.

(a) The Parties will cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns pursuant to this Article 8 and any audit, litigation or other Action with respect to Taxes.

(b) The Parties further agree, upon request, to use reasonable efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including without limitation with respect to the transactions contemplated by this Agreement).

9.1 Termination. This Agreement may be terminated in its entirety prior to the Closing:

(b) by either Seller or Buyer in the event of the issuance of a final, non-appealable Order or Law restraining, enjoining, or otherwise prohibiting or making illegal the consummation of the transactions contemplated by this Agreement;

(c) by either Buyer or Seller upon written notice to the other in the event of a material breach of any representation, warranty or covenant contained in this Agreement on the part of the other Party, which breach (i) would result in the failure of any condition to the terminating Party’s obligations set forth in Section 5 to be satisfied with respect to the Closing, and (ii) has not been cured within forty-five (45) days after the giving of written notice to the breaching Party of such breach; provided, however, that the right to terminate this Agreement under this Section 9.1(c) shall not be available to any Party if such Party is then in material breach of any of its representations, warranties or covenants hereunder; provided, further, that in no circumstance shall any failure or delay of FERC to issue an Order authorizing the transfer of the Purchased Interests under this Agreement be deemed or construed to be a breach by Seller or Buyer of any such representation, warranty or covenant; and

(d) by either Seller or Buyer if the Closing has not occurred on or before June 30, 2014; provided, however, that the right to terminate this Agreement under this Section 9.1(d) shall not be available to any Party that is then in material breach of any of its representations, warranties or covenants under this Agreement, or whose failure to take any action required to fulfill any of such Party’s obligations under this Agreement has caused or resulted in the failure of any Closing to occur prior to such date.

9.2 Effect of Termination. In the event of termination of this Agreement pursuant to Section 9.1, written notice thereof shall promptly be given by the terminating Party to the other Party, and this Agreement shall become null and void upon the effectiveness of such notice and there shall be no liability or obligation hereunder on the part Seller or Buyer, or any of their respective Representatives or Affiliates, as the case may be, except for Section 7.8(g), this Section 9.2, Section 9.3, and Article 10, which shall continue to apply following any such termination; provided, however, that no termination of this Agreement or any portion of the obligations hereunder shall relieve any Party of liability for breach of this Agreement occurring prior to such termination, except as provided in Section 9.3. The other Party shall take commercially reasonable steps to mitigate all Losses arising therefrom.

9.3 Limitations of Liability. In no event shall either Party be liable hereunder for any special, punitive, exemplary, incidental or consequential damages or lost profits, whether based on contract, tort, strict liability, other Law or otherwise and whether or not arising from the other Party’s sole, joint or concurrent negligence, strict liability or other fault for any matter relating to this Agreement and the transactions contemplated hereby.

10.1 No Effect on Contracts. The Parties acknowledge that Seller and/or certain of its Affiliates are obligated parties under certain of the Contracts to which the Subject Companies are party. Except as expressly provided in this Agreement, no provision hereof shall be construed as in any way modifying, decreasing, increasing, terminating, supplementing or in any other way modifying the representations, warranties or covenants of Seller and/or such Affiliates under any such Contracts.

10.2 No Third Party Beneficiaries. This Agreement shall not confer any rights or remedies upon any Person other than the Parties and their respective successors and permitted assigns.

10.3 Succession and Assignment. This Agreement shall be binding upon and inure to the benefit of the Parties named herein and their respective successors and permitted assigns. No Party may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written consent of the other Party. Notwithstanding the foregoing, (a) Buyer may assign its rights hereunder to any of its Affiliates, and (b) Buyer shall, prior to Closing, assign its rights hereunder to purchase not less than one percent (1.0%) of the issued and outstanding membership interests of Sponsor to Algonquin Power Fund (America) Holdco Inc. or another Affiliate that is treated as a separate tax payer from Buyer for federal income tax purposes; provided, however, that no such assignment shall result in a breach of any representation or warranty by Buyer hereunder.

10.4 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. The delivery of an executed counterpart of this Agreement by facsimile transmission or other electronic means shall be deemed to be effective as manual delivery thereof.

10.5 Headings. The section headings contained in this Agreement are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Agreement.

10.6 Notices. All notices, requests, demands, Actions, and other communications hereunder will be in writing. Any notice, request, demand, or other communication hereunder shall be deemed duly given two (2) Business Days after it is sent by registered or certified mail, return receipt requested, postage prepaid, and addressed to the intended recipient as set forth below:

Any Party may send any notice, request, demand, Action, or other communication hereunder to the intended recipient at the addresses set forth above using any other means (including personal delivery, expedited courier, messenger service, facsimile, or ordinary mail), but no such notice, request, demand, Action, or other communication shall be deemed to have been duly given unless and until it actually is received by the intended recipient. Any Party may change the address to which notices, requests, demands, Actions, and other communications hereunder are to be delivered by giving the other Party notice in the manner herein set forth.

10.7 Governing Law; Forum; Submission to Jurisdiction. This Agreement shall be governed by and construed and enforced in accordance with the Laws of the State of New York without regard to the conflicts of laws provisions thereof. Each Party hereby submits to the nonexclusive jurisdiction of the United States District Court and the courts of the State of New York, in either case sitting in the Borough of Manhattan for the purposes of all Actions arising out of or relating to this Agreement or the transactions contemplated hereby or thereby. Each Party irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of the venue of any such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum.

10.8 WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

10.9 Expenses; Attorney’s Fees. As between Buyer, on the one hand, and Seller, on the other hand, each Party shall (except as otherwise expressly provided in this Agreement) be responsible for its own costs and expenses, including any legal fees, incurred in connection with this Agreement and the transactions contemplated hereby. If any Action arising out of or related to this Agreement is brought by either Party, the prevailing Party shall be entitled to recover the costs and fees (including, without limitation, reasonable attorneys’ fees, the fees and costs of experts and consultants, copying, courier and telecommunication costs, and deposition costs and all other costs for discovery) incurred by such Party in such suit or Action, including, without limitation, any post-trial or appellate Action.

10.10 Amendments and Waivers. No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by Buyer and Seller. No waiver by any Party of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence.

10.11 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction.

10.12 Enforcement of the Agreement. In the event of any default under this Agreement, or breach of any of the terms, conditions and provisions of this Agreement, the Party who is thereby aggrieved will have the right of specific performance and injunctive relief giving effect to its rights under this Agreement, in addition to any and all other rights and remedies at law or in equity, and all such rights and remedies will be cumulative. The Parties agree that any such default or breach would cause irreparable injury, that the remedies at law for any such default or breach including monetary damages, are inadequate compensation for any loss and that any defense in any action for specific performance that a remedy at law would be adequate is waived.

10.13 Construction. The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement.

10.14 Incorporation of Exhibits. The Exhibits identified in this Agreement are incorporated herein by reference and made an integral part hereof.

10.15 Entire Agreement. This Agreement supersedes all prior discussions and agreements between the Parties with respect to the purchase and sale of the Purchased Interests, and contains the sole and entire agreement between the Parties with respect thereto. This Agreement supplements and amends, and is incorporated into as part and parcel of, the 60% MIPSA for all purposes (including the Buyer Parent Guaranty, the Seller Parent Guaranty, and the Gamesa Parent Indemnification Agreement); provided, however, for clarity, that except as herein amended, the 60% MIPSA shall remain in full force and effect and the Parties hereby ratify and confirm the terms, provisions and conditions thereof.

IN WITNESS WHEREOF, the Parties have executed this Agreement as of the date first above written.
