After receipt of the Statement and the Adjustment Statement, Seller will have thirty (30) days from receipt to review the Statement and the Adjustment Statement together with the workpapers used in their preparation.

Any items on the Statement or Adjustment Statement as to which Seller has not given notice of its objection and provided an alternative calculation on Seller's Statement will be deemed to have been agreed upon by the Parties. If Seller so notifies Purchaser of its objections to any of the Statement or the Adjustment Statement and provides Purchaser with Seller's Statement in a timely manner, the Parties will, within thirty (30) calendar days following such delivery of notice (the “Resolution Period”), attempt to resolve their differences. Any resolution by the Parties during the Resolution Period as to any disputed amounts will be final, binding and conclusive.

All fees and expenses relating to the work, if any, to be performed by the Neutral Accounting Arbitrator will be allocated between Purchaser, on the one hand, and Seller, on the other hand, in inverse proportion as they shall prevail on the amounts of such disputed items so submitted (as finally determined by the Neutral Accounting Arbitrator). The Neutral Accounting Arbitrator will deliver to the Parties a written determination (such determination to include a work sheet setting forth all material calculations used in arriving at such determination and to be based solely on information provided to the Neutral Accounting Arbitrator by the Parties) of the disputed items within thirty (30) days of receipt of the disputed items (or as soon as practicable thereafter), which determination will be final, binding and conclusive. The final, binding and conclusive Statement and Adjustment Statement, which either are agreed upon by the Parties or are delivered by the Neutral Accounting Arbitrator in accordance with this Section 2.03(d), will be the “Conclusive Statement” and the “Conclusive Adjustment Statement,” respectively. In the event that either Party fails to submit its statement regarding any items remaining in dispute within the time determined by the Neutral Accounting Arbitrator, then the Neutral Accounting Arbitrator shall render a decision based solely on the evidence timely submitted to the Neutral Accounting Arbitrator by the other Party.

If any portion of Losses to be reimbursed by the Indemnifying Party may be covered, in whole or in part, by

Exhibit 10.86

EXECUTION VERSION

CONFIDENTIAL TREATMENT REQUESTED

REDACTED VERSION

a Third Party Recovery, the Indemnified Party shall promptly give notice thereof to the Indemnifying Party or the Indemnifying Party may give notice thereof to the Indemnified Party (a “Notice of Third Party Recovery”). If the Indemnifying Party so requests within one hundred and eighty (180) days after receipt or delivery of a Notice of Third Party Recovery, the Indemnified Party shall use its commercially reasonable efforts to collect the maximum amount of Third Party Recoveries; provided that notwithstanding the foregoing, no Party's rights under this Article XI shall be limited during any period such Party is waiting to receive any such Third Party Recovery and no Indemnifying Party shall have any obligation to first submit or to collect upon any applicable Third Party Recovery as a precondition to making a claim for indemnification or set-off or obtaining indemnification or set-off for Losses therefor, and the Indemnifying Party agrees not to delay in any manner the payment to the Indemnified Party of such indemnifiable Loss or dispute the set-off rights exercised on the basis that the Indemnified Party has not yet fulfilled its obligations under this Section 11.04(e). If Purchaser, the Company, any Company Subsidiary or any of their Affiliates receives a Third Party Recovery after an indemnification payment is made or set-off rights are exercised, Purchaser shall promptly pay to Seller the amount of such Third Party Recovery at such time or times as and to the extent that such Third Party Recovery is actually received.

(f)The amount of any Loss subject to indemnification hereunder or any claim therefore shall be calculated net of any Tax benefit actually realized by Purchaser, the Company, any Company Subsidiary or any of their Affiliates as a result of such Loss. If Purchaser, the Company, any Company Subsidiary or any of their Affiliates actually receives a Tax benefit after an indemnification payment is made or set-off rights are exercised, Purchaser shall promptly pay to Seller the amount of such Tax benefit at such time or times as and to the extent that such Tax benefit is actually received.

(g)There shall be no recovery for any Loss or alleged Loss by Purchaser under this Article XI, and the Loss shall not be included in meeting the stated thresholds hereunder, to the extent such item has been included or a reduction to the Base Purchase Price paid at Closing on account of Estimated Transaction Expenses as determined pursuant to Section 2.04 hereof.

11.05. No Contribution. No Indemnifying Party or any of its employees or agents shall have any right of contribution, right of indemnity or other right or remedy against the Company or any Company Subsidiary in connection with any indemnification obligation or any other liability to which she, he or it may become subject under or in connection with this Agreement.

11.06. Information. No information or knowledge acquired, or investigations conducted, by Purchaser or its representatives or otherwise, shall in any way limit, or constitute a waiver of, or a defense to, any claim for indemnification or set-off by Purchaser or its Affiliates under this Agreement (it being understood that Purchaser has relied on the accuracy of the representations and warranties contained herein and the benefits provided by this Article XI or a result of any breach thereof in entering into this Agreement). No information or knowledge acquired, or investigations conducted, by the Company, Seller or their respective representatives, of Purchaser or otherwise, shall in any way limit, or constitute a waiver of, or a defense to, any claim for indemnification by Seller or any of its Affiliates under this Agreement (it being understood that the Seller and the Seller Parent have relied on the accuracy of the representations and warranties contained herein and the benefits provided by this Article XI or a result of any breach thereof in entering into this Agreement).

11.07. Set-Off. In the event Seller and Purchaser mutually agree that Seller is liable to pay a claim for indemnification by Purchaser under this Article XI or a final determination by a panel of arbitrators in accordance with Section 12.15 that Purchaser is entitled to indemnification under this Article XI, Purchaser

Exhibit 10.86

EXECUTION VERSION

CONFIDENTIAL TREATMENT REQUESTED

REDACTED VERSION

may withhold the amount of such indemnification from any and all payments of Austin Deferred Payments or Specified Project Deferred Payments or any other amounts owing from Purchaser to Seller under this Agreement.

11.08. Remedies Exclusive. Subject to the proviso below, after the Closing, the remedies provided in this Article XI are the sole and exclusive remedies available to a Party for any and all Losses resulting from the Transaction, the Projects, or any claim arising in connection with this Agreement by another Party (except that the foregoing shall in no way limit any rights or remedies of a Party under or pursuant to the Indemnity Escrow Agreement, Assignment Agreement or the Transition Services Agreement) except for the remedies of specific performance, injunction and other equitable relief; provided, however, that no Party shall be deemed to have waived any rights, claims, defenses, causes of action or remedies in instances of Fraud. From and after the Closing, notwithstanding anything to the contrary in this Agreement and except in instances of Fraud, (i) the indemnification provisions set forth in Section 11.01(a)(viii) and the reimbursement rights of Purchaser set forth in Section 6.15(a) constitute Purchaser's sole remedy with respect to Losses that constitute Specified Environmental Remediation Costs (it being understood that Purchaser shall not also be entitled to assert a claim for such Specified Environmental Remediation Costs as a result of a breach of the representations or warranties set forth in Section 4.15) and (ii) the indemnification provisions set forth in Section 11.01(a)(ix) with respect to those matters described on Schedule 11.02(a)(ix) shall constitute Purchaser's sole remedy with respect to Losses arising from the matters specifically described on Schedule 11.02(a)(ix) (it being understood, however, that to the extent that Purchaser incurs other Losses related to any of the projects referenced on Schedule 11.02(a)(ix) as a result of a breach of a representation and warranty or otherwise but such Losses are not Losses arising from the specific matters described on Schedule 11.02(a)(ix) the Purchaser shall have the remedies otherwise described in this Agreement with respect to such other Losses).

11.09. Non-Recourse. Except as expressly set forth in this Article XI, no Party shall have recourse whatsoever under this Agreement against any officer or director of the other Party (including for such purposes, any officer or director of any Affiliate of a Party). Without limiting the generality of the foregoing, except as expressly set forth in this Article XI, each Party, on behalf of itself and its Affiliates, hereby fully and irrevocably waives any right, claim or entitlement whatsoever against such officers or directors relating to any and all Liabilities suffered or incurred by any of them arising from, based upon, related to, or associated with this Agreement or the transactions contemplated hereby (including any breach, termination or failure to consummate such transactions) in each case whether based on contract, tort, strict liability other laws or otherwise and whether by piercing of the corporate veil, by claim on behalf of or by a Party hereto or other Person or otherwise.

11.10. Treatment of Indemnification. All indemnification payments made hereunder shall be treated by the Parties as adjustments to the Total Purchase Price.

Article XII.MISCELLANEOUS

This Agreement (together with that certain letter agreement between Purchaser and Seller dated as of the date hereof) supersedes all prior discussions and agreements among the Parties with respect to the subject matter hereof, excluding the Nondisclosure Agreement, and contains the sole and entire agreement among the Parties with respect to the subject matter hereof. Other than a claim for Fraud or a claim based on the Nondisclosure Agreement, prior to the Closing, no Party shall make any claim against any other Party resulting from the transactions contemplated hereby or the subject matter hereof, other than a claim made to enforce its rights under this Agreement (including

Exhibit 10.86

EXECUTION VERSION

CONFIDENTIAL TREATMENT REQUESTED

REDACTED VERSION

or contemplated by Section 12.13 hereof) or made for breach of the terms of this Agreement. Except as provided in Section 6.08 with respect to Indemnified Directors and Officers and their heirs, executors and representatives, and as provided in Article XI with respect to Indemnified Parties, this Agreement is for the sole benefit of the Parties and their successors and permitted assigns and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

12.02. Expenses. Except as otherwise contemplated in this Agreement: (i) Purchaser shall pay the fees and expenses of its counsel, accountants, experts, other representative and all other expenses incurred by any of them incident or relating to the negotiation, preparation and execution of this Agreement and the transactions contemplated hereby, and the performance by it of its obligations hereunder, and (ii) Seller, and not Purchaser, the Company or any Company Subsidiary, shall be ultimately responsible for all Transaction Expenses, whether by virtue of the provisions of Section 2.02 or 2.04 of this Agreement or otherwise.

12.03. Confidentiality. Unless and until the Closing occurs, the Parties will abide by the provisions of the Nondisclosure Agreement. If the Closing occurs, from and after the Closing Date, Seller will hold, and will cause its Affiliates and Representatives to hold, in strict confidence from any other Person all information and documents relating to the Projects and the Company, provided that nothing in this sentence shall limit the disclosure of any information (a) to the extent required by Applicable Law or a court of competent jurisdiction (provided that if permitted by Applicable Law, Seller agrees to give Purchaser prior notice of such disclosure in sufficient time to permit Purchaser to obtain a protective order should it so determine), (b) in connection with any litigation to which Seller or its Affiliates or Representatives is a party (provided that such Person has taken all reasonable actions to limit the scope and degree of disclosure in any such litigation), (c) in an Action brought by Seller in pursuit of its rights or in the exercise of its remedies under this Agreement, (d) to the extent that such documents or information can be shown to have come within the public domain through no action or omission of Seller or its Affiliates, and (e) to its Affiliates and Representative (but the Party shall be liable for any breach by its Affiliates and Representatives).

In case of a conflict between the Nondisclosure Agreement and this Section 12.03, the Nondisclosure Agreement shall govern issues arising prior to Closing and this Section 12.03 shall govern issues arising after the Closing .

12.04. Announcements. No press or other public announcement, or public statement or comment in response to any inquiry, relating to the transactions contemplated by this Agreement or the terms hereof shall be issued or made by any Party without the prior written approval of the other Party; provided that a press release or other public announcement, regulatory filing, statement or comment made without such joint approval shall not be in violation of this Section 12.04 if it is made in order for the disclosing Party or any of its Affiliates to comply with Applicable Laws or stock exchange rules and in the reasonable judgment of the Party making such release or announcement, based upon advice of counsel, prior review and joint approval, despite reasonable efforts to obtain the same, would prevent dissemination of such release or announcement in a sufficiently timely fashion to comply with such Applicable Laws or rules; and provided further that in all instances prompt notice from one Party to the other shall be given with respect to any such release,

No failure on the part of any Party to exercise and no delay in exercising, and no course of dealing with respect to, any right, remedy, power or privilege under this Agreement shall operate as a waiver of such right, remedy, power or privilege, nor shall any single or partial exercise of any right, remedy, power or privilege under this Agreement preclude any other or further exercise of any such right, remedy, power or privilege or the exercise of any other right, remedy, power or privilege.

12.09. Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions of this Agreement, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction, and in lieu of such prohibited or unenforceable provision, there will be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms to such prohibited or unenforceable provision as may be possible.

12.10. Assignment. The obligations of the Parties under this Agreement are not assignable without the prior written consent of the other Party, which such Party may withhold in its discretion.

12.11. Counterparts.

12.12. Disclosure.

(a)Each Party may, at its option, include in its Disclosure Schedule any items that are not

Exhibit 10.86

EXECUTION VERSION

CONFIDENTIAL TREATMENT REQUESTED

REDACTED VERSION

material in order to avoid any misunderstanding, and any such inclusion, or any references to dollar amounts, shall not be deemed to be an acknowledgment or representation that such items are material, to establish any standard of materiality or to define further the meaning of such terms for purposes of this Agreement.

(b)Each Disclosure Schedule shall be arranged, for purposes of convenience only, as separately titled Schedules corresponding to the certain sections of this Agreement. Information disclosed in any Schedule shall constitute a disclosure for purposes of all other Schedules of the same Disclosure Schedule notwithstanding the lack of specific cross-reference thereto, but only to the extent the applicability of such disclosure to such other Schedule is reasonably apparent from the face of the disclosure itself. In no event shall the inclusion of any matter in a Disclosure Schedule be deemed or interpreted to broaden the representations, warranties, covenants or agreements contained in this Agreement of the Party to which such Disclosure Schedule relates. The mere inclusion of an item in a Disclosure Schedule shall not be deemed an admission by the Party to which such Disclosure Schedule relates that such item represents a material exception or fact, event, or circumstance or that such item would be reasonably likely to result in a Material Adverse Effect. The information contained in each Disclosure Schedule is disclosed solely for the purposes of this Agreement, and no information contained therein shall be deemed to be an admission by any Party hereto to any third party of any matter whatsoever, including of any violation of law or breach of any agreement.

12.13. Specific Performance. The Parties agree that if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, money damages may not be a sufficient remedy and that the Parties shall be entitled to specific performance of the terms of this Agreement and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy, in addition to any other remedy at law or in equity.

12.14. Governing Applicable Law. This Agreement, the Transaction and all other transactions contemplated by this Agreement and all claims and defenses arising out of or relating to any such transaction or agreement or the formation, breach, termination or validity of any such agreement, shall in all respects be governed by, and construed in accordance with, the laws of the State of New York without giving effect to any conflicts of law principles of such state that would apply the Applicable Laws of another jurisdiction.

12.15. Arbitration.

(a)Except as provided in Section 12.16 below, any dispute, controversy or claim arising out of, relating to, or in connection with this Agreement (a “Dispute”) shall be finally settled by arbitration in accordance with this Section 12.15. The arbitration shall be conducted in accordance with the Rules of Arbitration of American Arbitration Association (“AAA”) in effect at the time of the arbitration, except as they may be modified herein or by mutual agreement of the Parties. By execution and delivery of this Agreement, each Party hereby accepts and consents to the jurisdiction of the arbitral tribunal. The Parties submit to the jurisdiction of the competent courts of New York for the purpose of enforcing this Agreement to arbitrate and/or any action to compel arbitration, any application for any interim, provisional or conservatory measure such as any pre-arbitral or other injunction or attachment (or similar relief) or enforcing an arbitral award or decision, or any proceeding permitted under this Section 12.15. In addition, the Parties agree not to seek any relief of any nature in respect of any Dispute from the courts of any jurisdiction or any Governmental Authority which would have the effect of frustrating any arbitration proceeding initiated in accordance with this Section 12.15 or be incompatible with this Section 12.15, including the agreement to arbitrate contained herein.

(b)The seat of the arbitration shall be New York, New York, and the English language

Exhibit 10.86

EXECUTION VERSION

CONFIDENTIAL TREATMENT REQUESTED

REDACTED VERSION

shall be used as the written and spoken language for the arbitration and all matters connected to the arbitration.

(c) The arbitration shall be conducted by three arbitrators. Each Party shall appoint one arbitrator within thirty (30) days after receipt of the request for arbitration. The two arbitrators shall appoint the third arbitrator within twenty one (21) days after the appointment of the later appointed of these two arbitrators. If any of the three arbitrators is not appointed within the time prescribed above, then AAA shall appoint that arbitrator. The arbitrators shall be attorneys or former or retired judges admitted to the bar of the State of New York and shall have practiced law for at least fifteen (15) years.

(d)The arbitrators shall have the power to grant any remedy or relief that they deem just and equitable and that is in accordance with the terms of this Agreement, including specific performance, and including, but not limited to injunctive or similar relief, whether interim or final, and any such relief, and any interim, provisional or conservatory measure ordered or granted by the arbitrators may specifically be enforced by any court of competent jurisdiction. Each Party retains the right to seek interim, provisional or conservatory measures or other relief as described in this Section 12.15 from judicial authorities and any such request shall not be deemed incompatible with the agreement to arbitrate or a waiver of the right to arbitrate.

(e)In order to facilitate the comprehensive resolution of related disputes, and upon request of any party to the arbitration proceeding, AAA may consolidate the arbitration proceeding with any other arbitration proceeding involving any of the Parties hereto relating to this Agreement. AAA shall not consolidate such arbitrations unless it determines that (i) there are issues of fact or law common to the two proceedings so that a consolidated proceeding would be more efficient than separate proceedings, and (ii) no party would be prejudiced as a result of such consolidation through undue delay or otherwise. AAA shall appoint all three members of the tribunal of the consolidated arbitration.

(f)Any award made by the arbitral tribunal shall be final and binding on the applicable Parties. To the extent applicable, the Parties hereto expressly agree to waive the applicability of any Applicable Law and regulations which would otherwise give the right to appeal any decision of the arbitral tribunal and so that there shall be no appeal to any court of law in relation to the award of the arbitral tribunal.

(g) During the pendency of any arbitration, each Party hereto shall continue to make all payments as and when due from it hereunder which are not in dispute, and perform all of its obligations hereunder which are not in dispute, and no Party hereto shall refer or attempt to refer the matter in dispute to any court or other tribunal in any jurisdiction, save as expressly provided in this Section 12.15.

(h)The non-prevailing Party shall pay all reasonable attorneys' and arbitrators' fees and expenses incurred by the prevailing Party in connection with the arbitration.

12.16. New York Courts. Notwithstanding any other provision of this Agreement, nothing in this Article 12 shall prevent a Party from seeking equitable relief by way of injunctive, specific performance or otherwise (as contemplated by Sections 12.13 and 12.15 and otherwise) from a court of competent jurisdiction located in New York, New York and each Party hereto irrevocably agrees to submit to the exclusive jurisdiction and venue of any such court for the purpose of any such suit, action or other proceeding.

12.17. Damages. Except in instances of Fraud, the Parties, on behalf of each of their respective Indemnified Parties, agree and acknowledge that no Party shall have the right to recover special, exemplary, or punitive damages or any consequential damages that are not also direct, compensatory damages, unless

Exhibit 10.86

EXECUTION VERSION

REDACTED VERSION

such special, exemplary, or punitive damages or any such consequential damages or other kind of special damages are awarded or paid in settlement to a Person in an indemnifiable Third Party Claim.

12.18. Waiver of Jury Trial. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH PARTY HEREBY WAIVES ALL RIGHTS TO A TRIAL BY JURY IN ANY LEGAL ACTION TO ENFORCE OR INTERPRET THE PROVISIONS OF THIS AGREEMENT OR THAT OTHERWISE RELATES TO THIS AGREEMENT.
