(b) Except for the payment obligations pro-rated to Seller under Section 3.6, or as specifically contemplated under Section 2.4, all liabilities and obligations under all agreements, contracts, undertakings, and licenses assigned to Purchaser under this Agreement, including the Facilities Contracts, and the Transferable Permits in accordance with the terms thereof, except in each case to the extent such liabilities and obligations were incurred by Seller prior to the Closing Date;

(1) Purchaser shall keep Seller informed of material developments related to such suits, actions, proceedings or investigations in a timely manner;

(2) Seller’s approval shall be required for any compromise or settlement of any liability or obligation of Seller, such approval not to be unreasonably withheld; and

(3) Seller’s approval shall be required for any admission of liability or guilt in any civil or criminal matter, with such approval at Seller’s sole discretion.

(ii) For all other suits, actions, proceedings or investigations, the Parties agree to coordinate with each other with respect to the defense thereof. Without limiting the foregoing, for suits, actions, proceedings or investigations in which Seller and Purchaser are named parties, Seller and Purchaser shall discuss the feasibility of having one counsel represent Seller and Purchaser.

2.6 Carbon Emission Allowances.

(a) To the extent that legislation and/or regulations creating and allocating Carbon Emission Allowances are adopted after the Effective Date, the Parties agree that Seller shall receive the Carbon Emission Allowances to which it would have been entitled if (i) the Facilities were operated through July 6, 2016 and (ii) Seller retained its current interest in the Facilities through that date. Accordingly:

(i) Carbon Emission Allowances allocated by a Governmental Authority before July 6, 2016: Seller will retain any Carbon Emission Allowances allocated to Seller, or attributable to a 48% share of the Units 4 and 5 at the Plant (“Seller’s Facilities Share”), and Purchaser will surrender to Seller any such Carbon Emission Allowances attributable to Seller’s Facilities Share, except that Seller will surrender to Purchaser or Purchaser will retain the Carbon Emission Allowances needed to cover the operation of Seller’s Facilities Share from the Closing through July 6, 2016. After the Closing, Seller shall have no obligation to purchase any Carbon Emission Allowances if the amount of Carbon Emission Allowances allocated to Seller or attributable to Seller’s Facilities Share is less than the amount needed to cover such operation;

(ii) Carbon Emission Allowances allocated by a Governmental Authority after July 6, 2016 based on any pre-July 6, 2016 measurement period: Seller will retain any Carbon Emission Allowances allocated to Seller, or attributable to Seller’s Facilities Share, and Purchaser will surrender to Seller any such Carbon Emission Allowances attributable to Seller’s Facilities Share; and

(iii) Carbon Emission Allowances allocated by a Governmental Authority after July 6, 2016 based on a post-July 6, 2016 measurement period: Seller will surrender to Purchaser or Purchaser will retain any such Carbon Emission Allowances.

(b) If, prior to July 6, 2016, Purchaser has the option of selecting a measurement period for Carbon Emission Allowances for the Facilities, then the Carbon Emission Allowances to be retained by or surrendered to Seller shall be calculated as if Purchaser had selected the measurement period which results in the highest amount of Carbon Emission Allowances retained by or surrendered to Seller.

2.7 California Capacity Rights. If the Closing Date occurs prior to October 1, 2012, Seller will have the month-by-month option to retain the capacity rights for the Seller’s Facilities Share for purposes of satisfying the requirements of California’s Resource Adequacy program for each month from the Closing Date until October 1, 2012. Seller may exercise such option by providing Purchaser with twenty days advanced prior written notice of the exercise of such option for each such month; provided that with respect to the month in which the Closing Date occurs, if Seller has not been able to provide twenty days advanced prior written notice, Seller shall be deemed not to have exercised such option. In no event shall Purchaser have any obligation to secure replacement capacity or any other remedy in the event the Facilities are not operating at full capacity. For any month after the Closing Date for which Seller retains the capacity rights for Seller’s Facilities Share, Purchaser shall, and shall have the exclusive authority to, submit or cause to be submitted all bids, including but not limited to supply bids for energy, self-schedules and self-provision of ancillary services for Seller’s Facilities Share in the California ISO day-ahead market, hour-ahead scheduling process and real-time market, as required for Seller to satisfy the requirements of California’s Resource Adequacy program. All revenues produced from such bids and self-schedules from the day-ahead market, hour-ahead scheduling process, real-time market and other revenues (including but not limited to revenues from ancillary services, the integrated forward market and residual unit commitment) related to Seller’s Facilities Share flowing from mechanisms other than the capacity market shall accrue to Purchaser. If the energy is called for, Purchaser will deliver such energy to the Moenkopi

Switchyard. Any wheeling costs for energy delivery incurred by Seller for delivery of energy from the Moenkopi Switchyard to the middle of the Colorado River will be netted from Purchaser’s market energy revenues.

ARTICLE 3
CLOSING

3.1 Closing. The closing of the sale of the Assets to, and the assumption of the Assumed Liabilities by, Purchaser (the “Closing”) will take place at the offices of Arizona Public Service Company, 000 Xxxxx Xxxxx Xxxxxx, Xxxxxxx, Xxxxxxx 00000, at 10:00 a.m. local time on the first day of the first full month following the date on which the conditions set forth in ARTICLE 8 and ARTICLE 9 have been either satisfied or waived by the Party for whose benefit such conditions precedent exist, or if such day is not a Business Day, on the next succeeding Business Day, or on such other date and at such other place as the Parties may mutually agree. The time and date of Closing is hereinafter called the “Closing Date.” Notwithstanding anything in this Agreement to the contrary, the Closing shall be deemed to have taken place at 12:01 a.m., Fruitland, New Mexico prevailing time, on the Closing Date, or if the Closing Date is not the first day of the month because such day is not a Business Day, on the first day of the month.

3.2 Purchase Price. At or, as applicable, after, the Closing, the Initial Purchase Price shall be adjusted, without duplication, to account for the following items and Closing Adjustments, and Post-Closing Adjustments, as set forth in Section 3.3, the sum of which is hereinafter referred to as the “Purchase Price”:

(a) Prorations. The Initial Purchase Price shall be adjusted to account for the items prorated as of the Closing Date pursuant to Section 3.6.

(b) Capital Expenditures. Subject to Section 6.6, the Initial Purchase Price will be increased by an amount equal to (i) the aggregate Capital Expenditures funded by Seller during 2010 and 2011 in excess of its share of the aggregate 2010 and 2011 capital budgets for the Facilities approved by the Facilities Owners, plus (ii) Capital Expenditures funded by Seller during 2012 and thereafter, until the Closing Date, in each case minus the amount of any depreciation Seller incurred as a result of such Capital Expenditures through the Closing Date; provided, however, that any costs or expenditures for which Seller is responsible under Section 2.4(i), or which are made on an emergency basis to address actual or anticipated equipment failures that would adversely affect the operating capacity of the Facilities prior to Closing and are economically viable to Seller (“Emergency Capital Expenditures”), will not increase the Initial Purchase Price; provided further that, with respect to Emergency Capital Expenditures made in 2012 and thereafter, Seller has received appropriate regulatory approval of cost recovery for such Emergency Capital Expenditures. For purposes of the foregoing, an Emergency Capital Expenditure will be considered economically viable if the net benefits to Seller associated with making the repair up to the Closing Date exceed the net costs to Seller associated with making the repair. This provision is intended only to address potential adjustments to the Initial Purchase Price, and is not intended to modify the parties’ rights and obligations under the Facilities Contracts.

(c) Timing of Closing. If the Closing Date is prior to October 1, 2012, the Initial Purchase Price shall be increased by Seven Million Five Hundred Thousand Dollars ($7,500,000) for each month between the Closing Date and October 1, 2012 and if the Closing Date is after October 1, 2012, the Initial Purchase Price shall be decreased by Seven Million Five Hundred Thousand Dollars ($7,500,000) for each month between October 1, 2012 and the Closing Date.

(d) California Capacity Rights. If Seller exercises its option under Section 2.7, the Initial Purchase Price shall be decreased by Three Million Dollars ($3,000,000) per month for each month for which Seller exercises its option to retain such capacity rights.

(e) Pension and OPEB Liabilities. If Seller’s Share of Underfunded/Overfunded Pension and OPEB Liabilities is greater than $0, the Initial Purchase Price shall be decreased by such amount, otherwise the Initial Purchase Price shall be increased by the absolute value of such amount, in each case, determined as of the Closing Date pursuant to Section 3.3(b).

3.3 Pre-Closing and Post-Closing Adjustments.

(a) At least thirty (30) calendar days prior to the Closing Date, Purchaser, with the assistance and participation of, and in consultation with, Seller, shall prepare and deliver to Seller an estimated closing statement (the “Estimated Closing Statement”) that shall set forth Purchaser’s best estimate of all estimated adjustments to the Initial Purchase Price required by Section 3.2 (the “Estimated Adjustment”). Within ten (10) calendar days after the delivery of the Estimated Closing Statement by Purchaser to Seller, Seller may object in good faith to the Estimated Adjustment in writing. If Seller objects to the Estimated Adjustment within such ten (10) day period, the Parties shall attempt to resolve their differences by negotiation. If the Parties are unable to do so prior to the Closing Date (or if Seller does not object to the Estimated Adjustment), the Initial Purchase Price shall be adjusted (the “Closing Adjustment”) at the Closing by the amount of the Estimated Adjustment not in dispute. The disputed portion shall be resolved in accordance with the provisions of Section 3.3(b) and paid as part of any Post-Closing Adjustment to the extent required by Section 3.3(b).

(b) Within sixty (60) days after the Closing Date, Purchaser, with the assistance and participation of, and in consultation with, Seller shall prepare and deliver to Seller a final closing statement (the “Post-Closing Statement”) that shall set forth all adjustments to the Initial Purchase Price proposed by Purchaser to be required by Section 3.2(a) through 3.2(e) not previously effected by the Closing Adjustment (the “Proposed Post-Closing Adjustment”); provided that if any adjustments to be made pursuant to Section 3.2(d) cannot be made within sixty (60) days after the Closing Date, the Parties agree that additional Post-Closing Statements can be subsequently prepared to address such adjustments. To the extent applicable, the Post-Closing Statement shall be prepared using the same accounting principles, policies and methods as the Operating Agent has historically used in connection with the calculation of the items reflected on such Post-Closing Statement. Without limiting the generality of the foregoing, for matters covered by Section 3.2(e), the discount rate and other assumptions used to determine Pension and OPEB Liabilities as reflected in the Post-Closing Statement shall be selected using the same methodology historically used for selecting the discount rate and assumptions for

Pinnacle West Capital Corporation’s consolidated fiscal year-end calculations reported in its audited financial statements. Within thirty (30) days after the delivery of the Post-Closing Statement by Purchaser to Seller, Seller may object in good faith to the Proposed Post-Closing Adjustment in writing, stating in reasonable detail its objections thereto. Purchaser and Seller agree to cooperate to exchange information used to prepare the Post-Closing Statement and information relating thereto. If Seller objects to the Proposed Post-Closing Adjustment, the Parties shall attempt to resolve such dispute by negotiation. If the Parties are unable to resolve such dispute within thirty (30) days after any objection by Seller, the Parties shall appoint the Independent Accounting Firm, which shall, at Seller’s and Purchaser’s joint expense, review the Proposed Post-Closing Adjustment and determine the appropriate adjustment to the Purchase Price, if any, within thirty (30) days after such appointment. The Parties agree to cooperate with the Independent Accounting Firm and provide it with such information as it reasonably requests to enable it to make such determination. For purposes of this Section 3.3(b) and wherever the Independent Accounting Firm is retained to resolve a dispute between the Parties, the Independent Accounting Firm may determine the issues in dispute following such procedures, consistent with the language of this Agreement, as it deems appropriate to the circumstances and with reference to the amounts in issue. No particular procedures are intended to be imposed upon the Independent Accounting Firm, it being the desire of the Parties that any such disagreement shall be resolved as expeditiously and inexpensively as reasonably practicable. The Independent Accounting Firm shall have no liability to the Parties in connection with such services except for acts of bad faith, willful misconduct or gross negligence, and the Parties shall provide such indemnities to the Independent Accounting Firm as it may reasonably request. The finding of such Independent Accounting Firm shall be binding on the Parties hereto. Upon determination of the appropriate adjustment (the “Post-Closing Adjustment”) by agreement of the Parties or by binding determination of the Independent Accounting Firm, the Party owing the difference shall deliver such amount to the other Party no later than two (2) Business Days after such determination, in immediately available funds or in any other manner as reasonably requested by the payee.

3.4 Payment. Any cash payments required by this Agreement shall be paid in U.S. dollars in immediately available funds. The recipient of such funds will designate the account or accounts to which the funds will be wire transferred.

3.5 Allocation of Purchase Price. The Parties will file all Tax Returns consistently with the allocation of the Purchase Price determined in accordance with this Section 3.5. The allocation of the Purchase Price (including any portion of the Assumed Liabilities if applicable) will be negotiated by the Parties in accordance with Applicable Tax Law (as defined below). Purchaser shall propose and deliver to Seller a preliminary allocation among the Assets of the Purchase Price and such other consideration to be paid to Seller pursuant to this Agreement (an “Allocation”) sufficiently far in advance of the Closing to allow the Final Pre-Closing Allocation referred to below to be determined prior to the Closing. The Allocation shall be consistent with Code Section 1060 (“Applicable Tax Law”) and the regulations thereunder and in a manner which facilitates Property Tax reporting and shall separately allocate Assets in the Facilities Switchyard. Seller shall within thirty (30) days thereafter propose any changes to the Allocation. Within thirty (30) days following delivery of such proposed changes, Purchaser shall provide Seller with a statement of any objections to such proposed changes, together with a reasonably detailed explanation of the reasons therefor. If Purchaser and Seller are unable to

resolve any disputed objections within ten (10) days thereafter, such objections shall be referred to the Independent Accounting Firm, which shall determine the Allocation (including any valuations). The Independent Accounting Firm shall be instructed to deliver to Purchaser and Seller a written determination of the proper allocation of such disputed items within twenty (20) Business Days from the date of engagement. Such determination shall be final, conclusive and binding upon the Parties for all purposes, and the Allocation shall be so adjusted (the allocation, including the adjustment, if any, to be referred to as the “Final Pre-Closing Allocation”). Within thirty (30) days of the determination of the Post-Closing Adjustment, the Parties shall agree to the adjustments to the Final Pre-Closing Allocation (“Final Allocation”). The fees and disbursements of the Independent Accounting Firm attributable to any Allocation shall be shared equally by Purchaser and Seller. Purchaser and Seller agree to timely file Internal Revenue Service Form 8594, and all Tax Returns, in accordance with such Allocation or Final Allocation, as the case may be, and to report the transactions contemplated by this Agreement for Federal Income tax and all other tax purposes in a manner consistent with the Allocation or Final Allocation, as the case may be. Purchaser and Seller agree to promptly provide the other Parties with any additional information and reasonable assistance required to complete Form 8594, or compute Taxes arising in connection with (or otherwise affected by) the transactions contemplated hereunder.

3.6 Prorations.

(a) Purchaser and Seller agree that, except as otherwise specifically provided in this Agreement, all of the budgeted, ordinary, and recurring items normally charged to the Facilities Owners, including those listed below (but not including any Income Taxes and Transfer Taxes), relating to the business and operation of the Assets, shall be prorated and charged as of the Closing Date, without any duplication of payment under the Facilities Contracts, with Seller liable to the extent such items relate to any time period prior to the Closing Date, and Purchaser liable to the extent such items relate to periods commencing with the Closing Date (measured in the same units used to compute the item in question, otherwise measured by calendar days):

(i) Property Taxes having a lien date in the same calendar year as the Closing Date, provided, however, with respect to any Property Taxes imposed by a Tribal Authority, such Property Taxes shall be prorated based upon that portion of the calendar year starting with the date of expiration of any applicable tax waiver and ending with the last day of the calendar year of the Closing Date;

(ii) Retrospective adjustments and policyholder distributions for the applicable period during which the Closing occurs with respect to Facilities Insurance Policies included in the Assets occurring within twelve (12) months of Closing or ninety (90) days after the year-end following the Closing, whichever occurs first; and

(iii) Operating and maintenance expenses incurred in any period prior to the Closing Date (not including Capital Expenditures) in the nature of the expenses shown on Schedule 3.6(a)(iii) but only to the extent that the amount of such expenses are determined within twelve (12) months of Closing or ninety (90) days after the year-end following the Closing, whichever occurs first.

(b) In connection with the prorations referred to in Section 3.6(a), in the event that actual figures are not available at the Closing Date, the proration shall be based upon the respective amounts accrued through the Closing Date or paid for the most recent year or other, appropriate period for which such amounts paid are available. All prorated amounts shall be recalculated and paid to the appropriate Party within sixty (60) days after the date that the previously unavailable actual figures become available. Seller and Purchaser shall furnish each other with such documents and other records as may be reasonably requested in order to confirm all proration calculations made pursuant to this Section 3.6.

3.7 No Assignment if Breach. To the extent that Seller’s rights under any of the Facilities Contracts to be transferred to Purchaser hereunder may not be assigned without the consent of another Person which consent has not been obtained, this Agreement shall not constitute an agreement to assign the same if an attempted assignment would constitute a breach thereof or be unlawful, and Purchaser and Seller shall cooperate and each use Commercially Reasonable Efforts to obtain any such required consent(s) as promptly as possible. Seller and Purchaser agree that if any consent to an assignment of any of the Facilities Contracts to be transferred hereunder shall not be obtained or if any attempted assignment would be ineffective or would impair Purchaser’s rights and obligations under the applicable Facilities Contracts so that Purchaser would not in effect acquire all such rights and obligations, Seller, to the maximum extent permitted by law and such Facilities Contracts, shall after the Closing appoint Purchaser to be Seller’s representative and agent with respect to such Facilities Contracts, and Seller shall, to the maximum extent permitted by law and such Facilities Contracts, enter into such reasonable arrangements with Purchaser as are necessary to transfer to Purchaser the benefits and obligations of such Facilities Contracts. Seller and Purchaser shall cooperate and shall each use Commercially Reasonable Efforts after the Closing to obtain an assignment of such Facilities Contracts to Purchaser.

Except as otherwise disclosed in writing by Purchaser to Seller contemporaneously with the execution of this Agreement, Purchaser has no Knowledge that it is in material violation of any applicable laws, orders, ordinances, rules, regulations or judgment of any Governmental Authority in existence as of the Effective Date with respect to the Assets, except for violations or alleged violations that are reasonably expected not to have a Material Adverse Effect.

5.5 Litigation. There is no claim, action, proceeding or investigation pending, or to Purchaser’s Knowledge, threatened against or relating to Purchaser or its Affiliates before any court, arbitrator or Governmental Authority, or any judgment, decree or order of any court, arbitrator or Governmental Authority, which could, individually or in the aggregate, reasonably be expected to result, or has resulted, in (a) the institution of legal proceedings to prohibit or restrain the performance of this Agreement or any of the Ancillary Agreements, or the consummation of the transactions contemplated hereby or thereby, (b) a claim against Seller or its Affiliates for damages as a result of Purchaser entering into this Agreement or any of the Ancillary Agreements, or the consummation by Purchaser of the transactions contemplated hereby or thereby, (c) a material impairment of Purchaser’s ability to perform its obligations under this Agreement or any of the Ancillary Agreements, or (d) a Material Adverse Effect.

5.6 Brokers. All negotiations relating to this Agreement and the transactions contemplated hereby have been carried on by Purchaser and in such a manner as not to give rise to any valid claim against Seller (by reason of Purchaser’s actions) for a brokerage commission, finder’s fee or other like payment to any Person.

5.7 Financing. Purchaser has now, and at the Closing Purchaser will have, liquid capital or committed sources therefor sufficient to permit Purchaser to perform timely its obligations hereunder and under the Ancillary Agreements.

5.8 Qualified for Permits. To Purchaser’s Knowledge, Purchaser is, or will be prior to the Closing, qualified to obtain any Facilities Permits necessary for the ownership and operation by Purchaser of the Assets as of the Closing in substantially the same manner as the Assets are currently operated.

ARTICLE 6
COVENANTS OF EACH PARTY

6.1 Efforts to Close.

(a) Commercially Reasonable Efforts. Subject to the terms and conditions herein provided, each of the Parties hereto agrees to use its Commercially Reasonable Efforts to consummate and make effective, as soon as reasonably practicable, the transactions contemplated hereby, including the satisfaction of all conditions thereto set forth herein. Such actions shall include, without limitation, exerting their Commercially Reasonable Efforts to (i) obtain the consents, authorizations and approvals of all private parties and any Governmental Authority whose consent is reasonably necessary to effectuate the transactions contemplated hereby, (ii) effect all other necessary registrations and filings, including, without limitation, filings under applicable laws, including the HSR Act and all other necessary filings with the CPUC, ACC, FERC (including applications to transfer the Facilities Switchyard), and any other Governmental Authority, and in the case of Purchaser, negotiate the extension or renewal referenced in Section 8.14 and the amendment referenced in Section 8.15. Each Party will provide the other with copies of all written communications from Governmental Authorities relating to the approval or disapproval of the transactions contemplated by the Agreement and the Ancillary Agreements.

(b) Expenses. Whether or not the transactions contemplated hereby are consummated, except as otherwise provided in this Agreement, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the Party incurring such expenses. Notwithstanding the foregoing:

(i) Costs associated with preliminary title reports and title policies shall be borne by Seller up to the costs that would have been incurred had the title policies been

standard coverage policies of title insurance, and the remaining costs, if any, including costs for extended coverage and any endorsements shall be borne by Purchaser (except that any survey costs shall be borne one-half by Purchaser and one-half by Seller);

(ii) Documentary transfer fees, if any, will be borne by Seller and recording costs and charges respecting real property will be borne one-half by Purchaser and one-half by Seller; and

(iii) Except as otherwise specifically set forth in Section 6.4, all fees, charges and costs of economists and other experts, if any, jointly retained by Purchaser and Seller in connection with submissions made to any Governmental Authority and advice in connection therewith respecting approval of the transactions will be borne one-half by Purchaser and one-half by Seller.

All such charges and expenses shall be promptly settled between the Parties at the Closing or upon termination or expiration of further proceedings under this Agreement, or with respect to such charges and expenses not determined as of such time, as soon thereafter as is reasonably practicable.

(i) Prior to Closing, Seller and/or Purchaser may, at their own cost and expense, conduct or cause to be conducted their own Phase 1 and Phase 2 environmental site assessments, and any follow up investigation, of the Facilities and the Facilities Switchyard as Seller and/or Purchaser deem necessary. The party conducting such assessments shall provide the other party with (1) a copy of any written reports resulting from such assessments; and (2) timely notice of any Environmental Condition(s) that require public disclosure or reporting to a regulatory authority or Remediation. Purchaser shall cooperate with and allow Seller to conduct such assessments and investigation. The results of such assessments and investigation shall not be binding on the Parties, and shall not be deemed to constitute an agreement by the Parties as to the existence or extent of current Environmental Conditions at the Facilities.

(ii) Following the Closing, Purchaser and Seller shall each appoint a representative to serve as an environmental liaison. Purchaser’s environmental liaison shall provide Seller’s environmental liaison with access to all information of Purchaser related to Environmental Conditions at the Facilities, consistent with Purchaser’s normal record creation and retention policies and subject to a reasonable and appropriate non-disclosure agreement. The liaisons will meet periodically to address questions of Seller and to discuss generally Environmental Conditions at the Facilities that would affect the Retained Environmental Liabilities, including the status of ongoing Remediation programs.

(iii) Without limiting the generality of the foregoing, Purchaser’s environmental liaison will provide Seller’s environmental liaison with notice of and documentation relating to the initiation of any legal action and any threatened legal action of which Purchaser becomes aware, in each case that could reasonably be expected to affect Retained Environmental Liabilities. Purchaser also will provide Seller’s liaison with a reasonable opportunity to review and comment on any new material Remediation initiative and

on environmental expenditures in the Facilities’ annual budgets that could reasonably be expected to affect Retained Environmental Liabilities. If requested by Seller’s liaison, Purchaser will present Seller’s views on such environmental expenditures to the Engineering and Operating Committee (as defined in the Facilities Operating Agreement), and will allow Seller to participate in such presentation.

(iv) If Seller’s liaison has significant concerns that an environmental matter will adversely affect Retained Environmental Liabilities, and the liaisons cannot satisfactorily address the concerns by themselves, the liaisons shall elevate the concerns to senior officers to be designated by each party prior to the Closing for further good faith discussions.

(v) The rights granted to Seller under this Section 6.1(c) shall not in any way alter or limit any rights retained by Seller under Section 2.1(h). In the event Purchaser transfers all or substantially all of the Assets to another Person and Purchaser is no longer the Operating Agent or a Facilities Owner, Purchaser shall cause such Person to assume Purchaser’s obligations to Seller under Sections 6.1(c)(ii) through (v), or make such other arrangements as are reasonably acceptable to Seller.

6.2 Updating. Seller shall promptly notify Purchaser of any changes or additions to any of Seller’s Schedules to this Agreement with respect to the Assets or Assumed Liabilities related thereto by the delivery of updates thereof, if any, as of a reasonably current date prior to the Closing, but in any event not later than three (3) Business Days prior thereto. No such updates made pursuant to this Section shall be deemed to cure any inaccuracy of any representation or warranty made in this Agreement as of the date hereof, unless Purchaser specifically agrees thereto in writing, nor shall any such notification be considered to constitute or give rise to a waiver by Purchaser of any condition set forth in this Agreement. Without limiting the generality of the foregoing, Seller shall notify Purchaser promptly of the occurrence of (i) any material casualty, physical damage, destruction or physical loss respecting, or any material adverse change in the physical condition of the Facilities or the Facilities Switchyard, subject to ordinary wear and tear and to routine maintenance, reasonably likely to result in a Material Adverse Effect, and (ii) any other material event likely to impair Seller’s ability to perform, if, in the cases of clauses (i) and (ii), the occurrence is one of which Seller has Knowledge and of which the Operating Agent does not have Knowledge.

6.3 Conduct Pending Closing. Prior to consummation of the transactions contemplated hereby or the termination or expiration of this Agreement pursuant to its terms, and except to the extent approved by Purchaser, Seller shall:

(a) Except as required by their terms, or except to the extent agreed to by all Facilities Owners (including Seller and Purchaser), not amend, terminate, renew, or renegotiate any existing Facilities Contract or enter into any new Facilities Contract, except in the ordinary course of business and consistent with practices of the recent past, or default (or take or omit to take any action that with or without the giving of notice or passage of time, would constitute a default) under any of its obligations under any Facilities Contract;

(b) Not: (i) sell, lease, transfer or dispose of, or make any contract for the sale lease, transfer or disposition of, any assets or properties which would be included in the Assets,

other than sales in the ordinary course of business which would not, individually or in the aggregate; have a Material Adverse Effect upon the operations or value of the Facilities or the Facilities Switchyard; (ii) incur, assume, guaranty, or otherwise become liable in respect of any indebtedness for money borrowed, in each case which would result in Purchaser assuming such liability hereunder after the Closing; (iii) delay the payment and discharge of any liability which, upon Closing, would be an Assumed Liability, because of the transactions contemplated hereby; (iv) encumber or voluntarily subject to any lien any Asset, except for Permitted Encumbrances or (v) except to the extent approved by the other Facilities Owners, not settle any claims against the Facilities or against Seller relating to the Facilities or the Facilities Contracts; and

(c) Not take any action which would cause any of Seller’s representations and warranties set forth in ARTICLE 4 to be materially false as of the Closing;

provided, that nothing in this Section 6.3 shall (i) preclude Seller from paying, prepaying or otherwise satisfying any liability which, if outstanding as of the Closing Date, would be an Assumed Liability or an Excluded Liability, or (ii) preclude Seller from incurring any liabilities or obligations to any third party in connection with obtaining such Party’s consent to any transaction contemplated by this Agreement or the Ancillary Agreements; provided that any such liabilities or obligations incurred pursuant to clause (ii) shall be Excluded Liabilities.

(d) Seller agrees to advise Purchaser of any request that Seller intends to file with the CPUC for approval of Capital Expenditures by Seller budgeted for 2012 and of any action taken by the CPUC with respect thereto. If the CPUC denies such request or CPUC approval is not received by November 30, 2011, the Parties will meet within 15 days thereafter to discuss the consequences of the CPUC denial or failure to act, including its potential impact on the 2012 capital budget for the Plant, the respective obligations of the Parties under the Facilities Contracts and the operation of the Plant in 2012; it being understood that there is no obligation of either Party to reach any agreement with respect to any of the matters discussed.

6.4 Consents and Approvals.

(a) Subject to Section 6.1(a), as promptly as practicable after the date of this Agreement, Seller and Purchaser shall each file or cause to be filed with the Federal Trade Commission and the Department of Justice all notifications required to be filed under the HSR Act and the rules and regulations promulgated thereunder with respect to the transactions contemplated hereby. The Parties shall consult with each other as to the appropriate time of filing such notifications and shall agree upon the timing of such filings, respond promptly to any requests for additional information made by either of such agencies, and cause the waiting periods under the HSR Act to terminate or expire at the earliest possible date after the date of filing. Purchaser and Seller shall be equally responsible for the cost of all filing fees under the HSR Act and each Party will bear its own costs for the preparation of any such filing.

(b) Subject to Section 6.1(a), as promptly as practicable after the date of this Agreement, Purchaser shall file with FERC any other applications required under the Federal Power Act for the purchase and sale contemplated hereby, which filing(s) may be made individually by Purchaser or jointly with Seller, as reasonably determined by the Parties.

(c) Subject to Section 6.1(a), Seller shall be responsible for obtaining CPUC approval of the transactions contemplated by this Agreement and the Ancillary Agreements, and Purchaser shall be responsible for obtaining ACC approval of the transactions contemplated by this Agreement and the Ancillary Agreements, in each case including the filing of the necessary applications therefor and diligently prosecuting any resulting proceedings. Each Party shall afford the other Party the opportunity to review such filings. Unless requested by the filing Party, the other Party agrees not to intervene in the regulatory proceedings related to the approval of the transaction.

(d) Subject to Section 6.1(a), Purchaser shall have the primary responsibility for securing the transfer, reissuance or procurement of the Facilities Permits, effective as of the Closing Date. Seller shall use Commercially Reasonable Efforts to cooperate with Purchaser’s efforts in this regard and assist in any transfer or reissuance of Facilities Permits held by Seller or the procurement of any other Facilities Permits when so requested by Purchaser.

(e) Within fifteen (15) days after the receipt of any Purchaser’s or Seller’s Required Regulatory Approval, the Party receiving such approval (the “Receiving Party”) shall notify the other Party in writing if the approval contains any condition that the Receiving Party determines could reasonably be expected to have a Material Adverse Effect on the Receiving Party or, in the case of Purchaser, on the Assets; provided, however, that if the Receiving Party does not provide such notice to the other Party within the fifteen (15) day period specified in this sentence, the Receiving Party shall be deemed to have accepted such Required Regulatory Approval, including any condition contained therein, and the condition to Closing set forth in Section 8.4 or Section 9.4, as applicable to such Party with respect to such Required Regulatory Approval, shall be deemed satisfied. Within fifteen (15) days after receipt of any notice specified in the previous sentence, Seller and Purchaser shall meet to consider what Commercially Reasonable Efforts the Receiving Party intends to take in order to obtain the Required Regulatory Approval or to eliminate the materially adverse conditions. After the Receiving Party has completed such agreed upon Commercially Reasonable Efforts with respect to the materially adverse condition contained in such Required Regulatory Approval, within fifteen (15) days of such completion or as soon as practicable thereafter, the Receiving Party shall notify the other Party, if the materially adverse condition has been eliminated or remains in effect, and whether the Receiving Party either will accept such materially adverse condition by a waiver of the applicable Closing condition in Section 8.4 or Section 9.4 with respect to such materially adverse condition or deem that the applicable Closing condition in Section 8.4 or Section 9.4 cannot be satisfied due to the materially adverse condition in such Required Regulatory Approval.

(f) From the date hereof through Closing, the Parties shall consult with each other at the senior management executive level prior to any party intervening in any regulatory proceeding of another Party, or commencing legal action or pursuing contractual remedies against any other Party with respect to the Facilities.

6.5 Tax Matters.

(a) All Transfer Taxes incurred in connection with this Agreement and the transactions contemplated hereby shall be borne one-half by Seller and one-half by Purchaser.

Seller will file, to the extent required by applicable law, all necessary Tax Returns and other documentation with respect to all such Transfer Taxes, and Purchaser will be entitled to review such returns in advance and, if required by applicable law, will join in the execution of any such Tax Returns or other documentation. Not less than five (5) Business Days prior to the due date of such Tax Returns, Purchaser shall pay Seller one-half of the amount shown as due on such Tax Returns, as determined in accordance, with this Agreement, and shall, to the extent required by Law, join in the execution of any such Tax Return. Prior to the Closing Date, Purchaser will provide to Seller, to the extent possible, an appropriate exemption certificate in connection with this Agreement and the transactions contemplated hereby, with respect to each applicable taxing authority.

(b) With respect to taxes to be prorated in accordance with Section 3.6 of this Agreement (except for pro-rated Property Taxes required to be paid by Seller), Purchaser shall prepare and timely file all Tax Returns required to be filed after the Closing with respect to the Assets, if any, and shall duly and timely pay all such Taxes shown to be due on such Tax Returns. For Property Tax purposes, any returns or filings with a lien or due date prior to Closing shall be prepared by Seller. Purchaser’s preparation of any such Tax Returns shall be subject to Seller’s approval, which approval shall not be unreasonably withheld or delayed. Purchaser shall make such Tax Returns available for Seller’s review and approval (which approval shall not be unreasonably withheld or delayed) no later than fifteen (15) Business Days prior to the due date for filing such Tax Returns, it being understood that Seller’s failure to approve any such Tax Returns shall not limit Purchaser’s obligation to timely file such Tax Returns and duly and timely pay all Taxes shown to be due thereon. Not less than five (5) Business Days prior to the due date of any such Tax Return, Seller shall pay to Purchaser the amount shown as due on such Tax Returns as determined in accordance with Section 3.6 of this Agreement and shall, to the extent required by law, join in the execution of any such Tax Returns.

(c) With respect to pro-rated Property Taxes, specifically including but not limited to Property Tax Returns prepared and filed with any Tribal Authority, Seller’s preparation of any such Tax Return shall be subject to Purchaser’s approval, which approval shall not be unreasonably withheld or delayed. Seller shall make such tax Returns available for Purchaser’s review and approval no later than fifteen (15) Business Days prior to the due date for filing such Tax Return, it being understood that Purchaser’s failure to approve any such Tax Return shall not limit Seller’s obligation to timely file such Tax Returns. In preparing and reviewing said Property Tax Returns, each Party shall cooperate and act in good faith to resolve any disagreement related to such Tax Returns as between the Parties or as between either Party and any Governmental Authority.

(d) Purchaser and Seller shall provide the other Party with such assistance as may reasonably be requested by the other Party in connection with the preparation of any Tax Return, any audit or other examination by any taxing authority, or any judicial or administrative proceedings relating to liability for Taxes, and each will retain and provide the requesting Party with any records or information which may be relevant to such return, audit or examination, proceedings or determination. Any information obtained pursuant to this Section 6.5 or pursuant to any other Section hereof providing for the sharing of information or review of any Tax Return

or other schedule relating to Taxes shall be kept confidential by the Parties hereto in accordance with Section 6.8.

(e) In the event that a dispute arises between Seller and Purchaser as to the amount of taxes, the Parties shall attempt in good faith to resolve such dispute, and any amount so agreed upon shall be paid to the appropriate Party. If such dispute is not resolved within thirty (30) days thereafter, the Parties shall submit the dispute to the Independent Accounting Firm for resolution, which resolution shall be final, conclusive and binding on the Parties. Notwithstanding anything in this Agreement to the contrary, the fees and expenses of the Independent Accounting Firm in resolving the dispute shall be borne equally by Seller and Purchaser. Any payment required to be made as a result of the resolution of the dispute by the Independent Accounting Firm shall be made within ten (10) days after such resolution, together with any interest determined by the Independent Accounting Firm to be appropriate.

(f) Seller hereby certifies that all Transfer Tax liabilities of Seller accruing before the Closing Date have been or will be fully satisfied or provided for. In the event Purchaser is assessed any Transfer Tax with respect to the Assets for any period prior to the Closing Date, Purchaser shall notify Seller promptly and shall provide Seller with a validly executed power of attorney authorizing Seller to act in Purchaser’s stead with regard to the assessment. Whether Seller determines to contest any such assessment in whole or in part, Seller shall indemnify and hold harmless Purchaser, in connection with any assessment of Tax described in this Section 6.5, whether or not contested hereunder, to the extent such Tax is determined to be due and owing, together with interest and penalties as well as any expenses incurred (including legal fees that may be incurred by Purchaser) in participating in any action related to such assessment. If the laws of the State or the local taxing authority require payment of assessed Taxes as a condition to contesting or further contesting their applicability, Seller shall make such payments together with interest and penalties. Purchaser agrees to cooperate fully in initiating and pursuing any action directed by Seller for recovery of such payments and shall refund any amounts received (including interest and penalties) within three (3) days of receipt by Purchaser. Any action to contest Tax assessments hereunder or to recover Taxes paid hereunder by Seller on behalf of Purchaser shall be under the control of Seller and at Seller’s sole cost and expense.

(g) Notwithstanding any other provision hereof, Purchaser covenants and agrees that, after the Closing Date, Purchaser will, to the extent practicable, and at Seller’s expense, (i) provide or cause to be provided written notice to Seller sixty (60) days in advance of taking any of the actions specified on a Schedule to be provided by Seller to Purchaser, within one hundred twenty (120) days of the Effective Date, which Schedule shall be reasonably acceptable to Purchaser; listing actions, including discontinuing the operation of the Facilities, or modifications to the Assets which in Seller’s reasonable opinion could result in a loss of the exclusion of interest on the Pollution Control Bonds from gross income for federal income tax purposes under Code Section 103, and (ii) take any reasonable actions which it has authority to take that are reasonably requested by Seller in writing for the purpose of maintaining such exclusion (including without limitation, inserting notification requirements, in operating manuals and posting notices within the Facilities). Notwithstanding anything in this Agreement to the contrary, (i) Purchaser will have no liability whatsoever in excess of $250,000 to Seller or any other Person if Purchaser fails to comply with the covenants in the preceding sentence and

(ii) Purchaser shall not be required to take, or refrain from taking, any action inconsistent with Purchaser’s rights or obligations under any of the Facilities Contracts. Purchaser further covenants and agrees that, in the event that Purchaser transfers any of the Assets, Purchaser, shall obtain from its transferee a covenant and agreement that is analogous to Purchaser’s covenants and agreements in this Section 6.5(g) pursuant to the first sentence of this Section 6.5(g) as well as a covenant and agreement that is analogous to that of this sentence. This covenant shall survive Closing and shall continue in effect so long as such Pollution Control Bonds remain outstanding. Seller agrees to promptly notify Purchaser at such time as no Pollution Control Bonds remain outstanding. Seller will reimburse Purchaser for any expenses incurred by Purchaser, in connection with Purchaser’s compliance with this Section 6.5(g). The term “Pollution Control Bonds” means the pollution control bonds specified on Schedule 6.5(g) and any refundings thereof, issued or to be issued on behalf of Seller in connection with the Assets.

6.6 Risk of Loss.

(a) Between the date hereof and the Closing Date, all risk of loss or damage to the property included in the Assets shall be borne by Seller.

(b) If, before the Closing Date, all or any portion of the Facilities or the Facilities Switchyard becomes subject to or is threatened with any condemnation or eminent domain proceeding, Seller shall notify Purchaser promptly in writing of such fact. If such taking would create a Material Adverse Effect, then Purchaser may, at its option, (i) receive from Seller an assignment of any claim, settlement or proceeds thereof and proceed with the transactions contemplated by this Agreement, or (ii) terminate this Agreement pursuant to Section 10.1.

(c) If, before the Closing Date all or any portion of the Facilities or the Facilities Switchyard are damaged or destroyed (whether by fire, theft, vandalism or other casualty) in whole or in part, and Seller’s share of the fair market value of such damage or destruction or the cost of repair of the Facilities or the Facilities Switchyard that were damaged, lost or destroyed is less than fifteen percent (15%) of the Initial Purchase Price, Seller shall, at its option, either (i) reduce the Purchase Price by the lesser of (x) Seller’s share of the fair market value of the Facilities or the Facilities Switchyard damaged or destroyed (such value to be determined as of the date immediately prior to such damage or destruction), or (y) Seller’s share of the estimated cost to repair or restore the same (any disagreement with respect thereto being resolved in accordance with Section 11.10), (ii) upon the Closing, transfer the proceeds or the rights to the proceeds of applicable insurance to Purchaser, or (iii) bear Seller’s share of the costs of repairing, or restoring such damaged or destroyed portions of the Facilities or the Facilities Switchyard and, at Seller’s election, delay the Closing and any right to terminate this Agreement for a reasonable time necessary to accomplish the same. If any part of the Facilities or the Facilities Switchyard is damaged or destroyed (whether by fire, theft, vandalism or other casualty) in whole or in part prior to the Closing and the lesser of Seller’s share of the fair market value of the Facilities or the Facilities Switchyard damaged or destroyed or Seller’s share of the cost of repair is greater than fifteen percent (15%) of the Initial Purchase Price, then Purchaser may elect either to (x) require Seller upon the Closing to transfer the rights to Seller’s share of proceeds (or the right to the proceeds) of applicable insurance to Purchaser and proceed with the transactions contemplated by this Agreement, or (y) terminate this Agreement.

6.7 Cooperation Relating to Insurance. Until the Closing, Seller will not take any action that will decrease the level of insurance coverage for the Facilities and the Facilities Switchyard as in effect on the date hereof, including, without limitation, property damage and liability insurance, unless agreed by the other Facilities Owners. In addition, Seller agrees to use Commercially Reasonable Efforts to assist Purchaser in making any claims against pre-Closing insurance policies of Seller that may provide coverage related to Assumed Liabilities. Purchaser agrees that it will indemnify Seller for its reasonable out-of-pocket expenses incurred in providing such assistance and cooperation. On and after the Closing, Seller authorizes the Operating Agent to take any actions necessary to remove Seller from any Facilities Insurance Policies and, except with respect to insurance rights retained by Seller pursuant to Sections 2.1(m), 2.1(o) or 2.2(h), Seller agrees to waive its rights with respect to such insurance coverage from and after the Closing. If requested by Seller, Purchaser agrees to exercise Commercially Reasonable Efforts to assist Seller, at Seller’s cost, in obtaining so-called “tail” coverage in respect of claims brought after the Closing for events occurring prior to the Closing, including, if appropriate, listing Seller as an additional insured or named insured in policies of Purchaser and/or the Facilities Owners. Seller agrees that it will reimburse Purchaser for its reasonable out-of-pocket expenses incurred in providing such assistance to Seller in obtaining tail coverage.

6.8 Confidentiality.

(a) General. Each Party (and its officers, employees, counsel, representatives and agents) will, using the same degree of care as that Party takes to preserve and safeguard its own confidential information, but not less than reasonable care, maintain in confidence and not disclose to third Persons, any Confidential Information received from the other Party (or its officers, employees, counsel, representatives and agents) in connection with the transactions contemplated by this Agreement. Each Party may disclose Confidential Information received from the other Party if and to the extent required by law, court order, subpoena or other lawful order of a Governmental Authority with jurisdiction, provided that the other Party is given written notice of such disclosure ten (10) days in advance, or as soon in advance as is reasonably practicable, or with the prior written consent of the other Party. If this Agreement is terminated pursuant to ARTICLE 10, each Party will return promptly, if so requested by the other Party, any Confidential Information provided to it and will use Commercially Reasonable Efforts to return any copies thereof that may have been provided to others in accordance with this Section 6.8. To the extent practicable, the Parties further agree, subject to Section 6.11, to not issue any public announcement, statement, press release or other public disclosure with respect to this Agreement or the transactions contemplated hereby; without the prior written consent of the other Party, which consent will not be unreasonably withheld. To the extent the provisions of this Section 6.8(a) conflict with the Confidentiality Agreement, as between Seller and Purchaser, this Section 6.8(a) shall control.

(b) Regulatory Agencies. Subject to Section 6.1(a), upon the other Party’s prior written approval (which, except as provided below, will not be unreasonably withheld), either Party may provide Confidential Information to the CPUC, ACC, FERC or any other Governmental Authority with jurisdiction as necessary to obtain Seller’s Required Regulatory Approvals or Purchaser’s Required Regulatory Approvals or approval under the HSR Act. The disclosing Party will seek confidential treatment for the Confidential Information provided to any

Governmental Authority and the disclosing Party will notify the other Party as far in advance as is practicable of its intention to release to any Governmental Authority any Confidential Information.

6.9 Reasonable Cooperation. Each Party agrees to use Commercially Reasonable Efforts to cooperate with the other Party to effect the consummation of the transactions contemplated by this Agreement, and to provide the other Party with such access or information related to the Facilities as may reasonably be requested in connection with such transactions. Without limiting the generality of the forgoing, the Parties shall work with each other prior to the Closing Date to determine if any Facilities Contract which is not currently listed on Schedule 1.1.67 or Schedule 1.1.77, or approval of any Governmental Authority which is not currently listed on Schedule 1.1.67 or Schedule 1.1.77, should be listed on such Schedule.

6.10 Title to Real Property and Leased Property. As soon as reasonably possible after the Effective Date, Seller and Purchaser shall work cooperatively to cause Title Insurer to deliver a current preliminary title report on the real property and leased property included in the Assets, accompanied by legible copies of all documents referred to in the exception portion of such report, to Purchaser (the “Preliminary Title Report”). Purchaser shall have not more than thirty (30) days from the delivery date of the Preliminary Title Report in which to review and to give Seller and Title Insurer written notice of any title exception which is unacceptable to Purchaser, and, in the event any amendment is issued to the Preliminary Title Report, Purchaser shall have not more than thirty (30) days from the delivery of an amendment to deliver a written objection to any title exception, appearing for the first time in such amendment. If Purchaser is dissatisfied with any exception to title as shown in the Preliminary Title Report, then, Seller shall have until the Closing to eliminate any disapproved exceptions from the Preliminary Title Report, or obtain title insurance endorsements against such exceptions. If Seller cannot remove such exceptions or obtain title insurance endorsements before the Closing, then Purchaser may either cancel this Agreement, or Purchaser may waive such objections and the transaction shall close as scheduled, provided that if Purchaser disapproves any title exception that would otherwise qualify as a Permitted Encumbrance under Section 1.1.60 but for Purchaser’s position that such title exception constitutes or will constitute a Material Adverse Effect, then Seller shall have the right to terminate this Agreement on fifteen (15) Business Days’ notice given within thirty (30) days following Purchaser’s disapproval of such title exception. Notwithstanding any other provision hereof, the following exceptions shall be deemed accepted by Purchaser and need not be removed or endorsed over: (a) Permitted Encumbrances, and (b) exceptions not objected to in writing by Purchaser during the time periods set forth above.

6.11 Right of First Refusal. Seller hereby agrees to promptly orally notify Purchaser, confirmed in writing, as to any notices received by Seller pursuant to Section 13 of the Facilities Co-Tenancy Agreement regarding the Facilities Owners’ right of first refusal. If one or more of the Facilities Owners exercises their right of first refusal with respect to the Assets under the Facilities Co-Tenancy Agreement, Purchaser shall, subject to the terms and conditions of the Facilities Co-Tenancy Agreement and without limitation of any of the rights of the other the Facilities Owners thereunder, automatically and without further notice to Seller be deemed to have exercised its right of first refusal with respect to the Assets to the maximum extent permitted by the Facilities Co-Tenancy Agreement. In the event one or more of the Facilities Owners exercises such right, the interest in the Assets to be transferred pursuant to this

Agreement and the Initial Purchase Price shall both be reduced to reflect the pro rata interest in the Assets to be purchased by Purchaser pursuant to Section 13.10 of the Facilities Co-Tenancy Agreement or as otherwise agreed to by Seller, Purchaser and the Facilities Owner exercising its right of first refusal, and Seller and Purchaser will enter into an amendment to this Agreement to reflect such reductions and other changes that the Parties deem appropriate.

6.12 Exclusivity. During the term of this Agreement, and except as necessary to fulfill its obligations under the Facilities Co-Tenancy Agreement, or an order of the CPUC, Seller will (a) deal exclusively with Purchaser and other Facilities Owners that elect to participate in the purchase of the Assets under this terms of this Agreement (“Participating Owners”), and will not offer to sell, solicit offers to sell or negotiate with any third party for the sale of the Assets; and (b) promptly notify Purchaser and Participating Owners of any unsolicited offer, interest or inquiry by a third party concerning a possible purchase of the Assets and will not provide any information with respect to a possible sale of the Assets to any third party.

6.13 Post Closing — Further Assurances. 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 terms of this Agreement or realize the benefits intended to be afforded hereby. After the Closing, and upon prior reasonable request, each Party shall exercise Commercially Reasonable Efforts to cooperate with the other, at the requesting Party’s expense (but including only out-of-pocket expenses to third parties and not the costs incurred by any Party for the wages or other benefits paid to its officers, directors or employees), in furnishing non-privileged records, information, testimony and other assistance in connection with any inquiries, actions, audits, proceedings or disputes involving either of the Parties hereto (other than in connection with disputes between the Parties hereto) and based upon contracts, arrangements or acts of Seller, Purchaser, the other Facilities Owners or the Operating Agent on behalf of one or more of the Facilities Owners which were in effect or occurred on, prior to, or after Closing and which relate to the Assets, including, without limitation, arranging discussions with (and calling as a witness) officers, directors, employees, agents, and representatives of Purchaser or Seller.

6.14 Post Closing — Information and Records.

(a) Following the Closing, Purchaser will not dispose of any books, records, documents or information reasonably relating to any Excluded Assets or Excluded Liabilities except in accordance with Purchaser’s existing record retention policies.

Seller will provide reasonable notice to Purchaser of its need to access such books, records, documents or other information.

(b) Seller shall not be entitled to examine or copy privileged and/or attorney work product documents or information pursuant to Section 6.14(a). If privileged and/or attorney work product documents or information, including communications between Purchaser and its counsel, are disclosed to Seller in the books, records, documents or other information

made available by Purchaser, Seller agrees (1) such disclosure is inadvertent, (2) such disclosure will not constitute a waiver, in whole or in part, of any privilege or work product, (3) such information will constitute Confidential Information, and (4) Seller will promptly return to Purchaser (or will destroy or make inaccessible such Confidential Information to the extent reasonably possible and certify as such to Purchaser) all copies of such books, records, documents or other information in the possession of Seller.

6.15 Post Closing — Landfill and Remediation Costs. Purchaser covenants that: (a) it shall not cause the Landfill to be used or operated at any time after the Closing; and (b) in the event that Purchaser, without Seller’s approval, enters into (i) any lease or lease amendment or extension or (ii) any other agreement of any kind with a Person other than a Governmental Authority, in either case altering or purporting to alter in any material respect any obligations of Seller with respect to Remediation of any Environmental Conditions or Hazardous Substances or the removal or Remediation of the Landfill, Purchaser shall hold Seller harmless from any incremental Remediation or removal costs, resulting from such lease, lease amendment or extension or other agreement.

ARTICLE 7
INDEMNIFICATION

7.1 Indemnification by Seller.

(a) Purchaser Claims. From and after the Closing, Seller will indemnify, defend and hold harmless Purchaser and its parents and Affiliates, and each of their officers, directors, employees, attorneys, agents and successors and assigns (collectively, the “Purchaser Group”), from and against any and all demands, suits, penalties, obligations, damages, claims, losses, liabilities, payments, costs and expenses (including reasonable legal, accounting and other expenses in connection therewith) and including costs and expenses incurred in connection with investigations, and settlement proceedings which arise out of, in connection with, or relate to, the following (collectively, “Purchaser Claims”):

(i) any breach or violation of any covenant or agreement of Seller set forth in this Agreement;

(ii) any breach or inaccuracy of the representations or warranties made by Seller contained in this Agreement in ARTICLE 4;

(iii) the Excluded Liabilities; and

(iv) any loss or damages resulting from or arising out of Seller’s ownership of the Assets prior to Closing, except for any loss or damage resulting from or arising out of Assumed Liabilities.

(b) Seller Limitations. If the Closing occurs, the Purchaser Group will not be entitled to any punitive, incidental, indirect, special or consequential damages resulting from or arising out of any Purchaser Claims, including damages for lost revenues, income, profits or tax benefits, diminution in value of the Facilities, or any other damage or loss resulting from the

disruption to or loss of operation of the Assets, except to the extent due on any Third Party Claim.

7.2 Indemnification by Purchaser.

(a) Seller Claims. From and after the Closing, Purchaser will indemnify, defend and hold harmless Seller and its parents and Affiliates and each of their officers, directors, employees, attorneys, agents and successors and assigns (collectively, the “Seller Group”), from and against any and all demands, suits, penalties, obligations, damages, claims, losses, liabilities, payments, costs and expenses (including reasonable legal, accounting and other expenses in connection therewith) and including costs and expenses incurred in connection with, investigations and settlement proceedings which arise out of or relate to the following (collectively, “Seller Claims”):

(i) any breach or violation of any covenant or agreement of Purchaser set forth in this Agreement;

(ii) any breach or inaccuracy of any of the representations or warranties made by Purchaser contained in this Agreement in ARTICLE 5;

(b) Purchaser Limitations. If the Closing occurs, the Seller Group will not be entitled to any punitive, incidental, indirect, special or consequential damages resulting from or arising out of any Seller Claim, including damages for lost revenues, income, profits or tax benefits, diminution in the value of the Facilities or any other damage or loss resulting from the disruption to or loss of operation of the Assets, except to the extent due on any Third Party Claim.

7.3 Notice of Claim. Subject to the terms of this Agreement and upon a Party’s receipt of notice of the assertion of a claim or of the commencement of any suit, action or proceeding made or brought by any Person who is not a Party to this Agreement or an Affiliate, the Party seeking indemnification hereunder (the “Indemnitee”) will promptly notify the Party against whom indemnification is sought (the “Indemnitor”) in writing of any damage, claim, loss, liability or expense which the Indemnitee has determined has given or could give rise to a claim under Section 7.1 or Section 7.2. (The written notice is referred to as a “Notice of Claim.”) A Notice of Claim will specify, in reasonable detail, the facts known to the Indemnitee regarding the claim. Subject to the terms of this Agreement, the failure to provide (or timely provide) a Notice of Claim will not affect the Indemnitee’s rights to indemnification; provided, however, the Indemnitor is not obligated to indemnify the Indemnitee for the increased amount of any claim which would otherwise have been payable to the extent that the increase resulted from the failure to deliver timely a Notice of Claim.

7.4 Defense of Third Party Claims. The Indemnitor will defend, in good faith and at its expense, any claim or demand set forth in a Notice of Claim relating to a Third Party Claim and the Indemnitee, at its expense, may participate in the defense. The Indemnitee cannot settle or compromise any Third Party Claim so long as the Indemnitor is defending it in good faith. If the Indemnitor elects not to contest a Third Party Claim, the Indemnitee may undertake its defense, and the Indemnitor will be bound by the result obtained by the Indemnitee. The Indemnitor may at any time request the Indemnitee to agree to the abandonment of the contest of the Third Party Claim or to the payment or compromise by the Indemnitor of the asserted claim or demand. If the Indemnitee does not object in writing within fifteen (15) days of the Indemnitor’s request, the Indemnitor may proceed with the action stated in the request. If within that fifteen (15) day period the Indemnitee notifies the Indemnitor in writing that it has determined that the contest should be continued, the Indemnitor will be liable under this ARTICLE 7 only for an amount up to the amount which the third party to the contested Third Party Claim had agreed to accept in payment or compromise as of the time the Indemnitor made its request. This Section 7.4 is subject to the rights of any Indemnitee’s insurance carrier that is defending the Third Party Claim.

7.5 Cooperation. The Party defending the Third Party Claim will (a) consult with the other Party throughout the pendency of the Third Party Claim regarding the investigation, defense, settlement, trial, appeal or other resolution of the Third Party Claim; and (b) afford the other Party the opportunity to be associated in the defense of the Third Party Claim. The Parties will cooperate in the defense of the Third Party Claim. The Indemnitee will make available to the Indemnitor or its representatives all records and other materials reasonably required by them for use in contesting any Third Party Claim (subject to obtaining an agreement to maintain the confidentiality of confidential or proprietary materials in a form reasonably acceptable to Indemnitor and Indemnitee). If requested by the Indemnitor, the Indemnitee will cooperate with the Indemnitor and its counsel in contesting any Third Party Claim that the Indemnitor elects to contest or, if appropriate, in making any counterclaim against the Person asserting the claim or demand, or any cross-complaint against any Person. The Indemnitor will reimburse the Indemnitee for any expenses incurred by Indemnitee in cooperating with or acting at the request of the Indemnitor.

7.6 Mitigation and Limitation on Claims. As used in this Agreement, the term “Indemnifiable Claim” means any Purchaser Claims or Seller Claims. Notwithstanding anything to the contrary contained herein:

(a) Reasonable Steps to Mitigate. The Indemnitee will take all reasonable steps to mitigate all losses, damages and the like relating to an Indemnifiable Claim, including availing itself of any defenses, limitations, rights of contribution, claims against third Persons and other rights at law or equity, and will provide such evidence and documentation of the nature and extent of the Indemnifiable Claim as may be reasonably requested by the Indemnitor. The Indemnitee’s reasonable steps include the reasonable expenditure of money to mitigate or otherwise reduce or eliminate any loss or expense for which indemnification would otherwise be due under this ARTICLE 7, and the Indemnitor will reimburse the Indemnitee for the Indemnitee’s reasonable expenditures in undertaking the mitigation, together with, interest thereon from the date of payment to the date of repayment at the “prime rate” as published in The Wall Street Journal.

(b) Net of Benefits. Any Indemnifiable Claim is limited to the amount of actual damages sustained by the Indemnitee by reason of such breach or nonperformance.

(c) Minimum Claim. No Party shall have any liability or obligation to indemnify under Section 7.1(a)(ii) or Section 7.2(a)(ii), as the case may be, unless the aggregate amount for which such Party would be liable thereunder, but for this provision, exceeds One Million Dollars ($1,000,000), and recovery shall be limited only to such amounts as exceed One Million Dollars ($1,000,000). For purposes of the foregoing, individual claims of Fifteen Thousand Dollars ($15,000) or less shall not be aggregated for purposes of calculating such deductible threshold amount or for calculating damages in excess of such amount. Nothing in this Section 7.6 is intended to modify or limit a Party’s liability or obligation hereunder for other Indemnifiable Claims or to constitute an assumption by Purchaser of any Excluded Liability or an assumption by Seller of any Assumed Liability.

7.7 Exclusivity. Except for intentional fraud, following the Closing, the rights and remedies of Seller, on the one hand, and Purchaser, on the other hand, for money damages under this Article are, solely as between Seller on the one hand and Purchaser on the other hand, exclusive and in lieu of any and all other rights and remedies for money damages which each of Seller on the one hand, and Purchaser on the other hand, may have under this Agreement under applicable Law with respect to any Indemnifiable Claim, whether at common law or in equity.

(a) by Seller if there has been a misrepresentation with respect to Purchaser’s representations and warranties in this Agreement (without giving effect to materiality, Material Adverse Effect, or similar phrases in such representations and warranties) that would result in a Material Adverse Effect, or a material default or breach by Purchaser with respect to the due and timely performance of any of Purchaser’s covenants and agreements contained in this Agreement, and such misrepresentation; default or breach is not cured by the earlier of the Closing Date or the date thirty (30) days after receipt by Purchaser, of written notice specifying particularly such misrepresentation, default or breach;

(f) by mutual agreement of Seller and Purchaser; or

MISCELLANEOUS AGREEMENTS AND ACKNOWLEDGMENTS

11.1 Purchaser as Operating Agent. Notwithstanding the sale of the Assets and the assignment of the Facilities Contracts by Seller to Purchaser, the actions or inactions of Purchaser, in its capacity as Operating Agent, insofar as they may affect Retained Environmental Liabilities or Excluded Liabilities, shall continue to be subject to the standard of conduct and the limitations on liability set forth in Section 22 of the Facilities Operating Agreement in effect at the time of Closing and the retention by Seller of Retained Environmental Liabilities and of rights under the Facilities Contracts with respect to Excluded Liabilities shall not impose a different standard of conduct on Purchaser, in its capacity as Operating Agent, or change in any manner the limitations of liability of Purchaser, in its capacity as Operating Agent, to Seller under the Facilities Contracts with respect to any actions or inactions of the Operating Agent that may affect Retained Environmental Liabilities or Excluded Liabilities. Nothing contained in this Section 11.1 shall excuse or limit Purchaser’s performance of the specific covenants set forth in this Agreement in accordance with their terms.

11.2 Expenses. Except as otherwise provided herein, each Party is responsible for its own costs and expenses (including attorneys’ and consultants’ fees, costs and expenses) incurred in connection with this Agreement and the consummation of the transactions contemplated by this Agreement.

11.3 Entire Document. This Agreement (including the Exhibits and Schedules to this Agreement) the Ancillary Agreements and the Confidentiality Agreement contain the entire agreement between the Parties with respect to the transactions contemplated hereby and supersede all negotiations, representations, warranties, commitments, offers, contracts and writings (except for the Confidentiality Agreement) prior to the execution date of this Agreement, written or oral. No waiver and no modification or amendment of any provision of this Agreement is effective unless made in writing and duly signed by the Parties referring specifically to this Agreement, and then only to the specific purpose, extent and interest so provided.

11.4 Schedules. The Parties agree and acknowledge that the Schedules in this Agreement may be incomplete or subject to revision prior to the Closing, subject to Section 6.2. The Parties will cooperate and work in good faith to complete and update such Schedules in a manner consistent with the requirements of this Agreement. The Schedules delivered pursuant to the terms of this Agreement are an integral part of this Agreement to the same extent as if they were set forth verbatim herein.

11.5 Counterparts. This Agreement may be executed in one or more counterparts, each of which is an original, but all of which together constitute one and the same instrument.

11.6 Severability. If any provision hereof is held invalid or unenforceable by any arbitrator or as a result of future legislative action, this holding or action will be strictly construed and will not affect the validity or effect of any other provision hereof. To the extent permitted by law, the Parties waive, to the maximum extent permissible, any provision of law that renders any provision hereof prohibited or unenforceable in any respect.

11.7 Assignability. This Agreement is binding upon and inures to the benefit of the successors and assigns of the Parties, but is not assignable by any Party without the prior written consent of the other Party.

11.8 Captions. The captions of the various Articles, Sections, Exhibits and Schedules of this Agreement have been inserted only for convenience of reference and do not modify, explain, enlarge or restrict any of the provisions of this Agreement.

11.9 Governing Law. The validity, interpretation and effect of this Agreement are governed by and will be construed in accordance with the laws of the state in which the Facilities are located applicable to contracts made and performed in such state and without regard to conflicts of law doctrines except to the extent that certain matters are preempted by Federal law or are governed by the law of the jurisdiction of organization of the respective Parties.

11.10 Dispute Resolution.

(a) Intent of the Parties. Subject to ARTICLE 7 with respect to an Indemnifiable Claim, Section 3.2(e) with respect to Post-Closing Adjustments, Section 3.5 with respect to the Purchase Price allocation, and Section 6.5(e) with respect to disputes regarding Taxes, and except as provided in Section 11.10(b), the sole process available to either Party for resolution of any dispute or claim arising out of or relating to this Agreement or any Ancillary Agreement shall be the dispute resolution procedure set forth in this Section 11.10. If the Parties

cannot resolve a dispute under Sections 11.10(c) or (d), then the dispute shall be settled through final and binding arbitration under Section 11.10(e).

(b) Provisional Relief. The Parties acknowledge and agree that irreparable damage would occur if certain provisions of this Agreement are not performed in accordance with the terms of this Agreement, that money damages would not be a sufficient remedy for any breach of these provisions of this Agreement, and that the Parties shall be entitled, without the requirement of posting a bond or other security, to seek a preliminary injunction, temporary restraining order, or other provisional relief as a remedy for a breach of this Agreement in any court of competent jurisdiction, notwithstanding the obligation to submit all other disputes (including all claims for monetary damages under this Agreement) to mediation and arbitration pursuant to Sections 11.10(d) or (e). The Parties further acknowledge and agree that the results of the arbitration may be rendered ineffectual without the provisional relief. Such a request for provisional relief does not waive a Party’s right to seek other remedies for the breach of the Agreement, notwithstanding any prohibition against claim-splitting or other similar doctrine. The other remedies that may be sought include specific performance and injunctive or other equitable relief, plus any other remedy specified in this Agreement for the breach of the provision, or if the Agreement does not specify a remedy for the breach, all other remedies available at law or equity to the Parties for the breach.

(c) Management Negotiations. The Parties will attempt in good faith to resolve any dispute or claim arising out of or relating to this Agreement or an Ancillary Agreement promptly by negotiations between a vice president (or more senior officer) of Seller or his or her designated representative and an executive of similar authority of Purchaser. Either Party may give the other Party written notice of any dispute or claim. Within twenty (20) days after delivery of said notice, the executives will confer by telephone or meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary to exchange information and to attempt to resolve the dispute or claim. If the matter has not been resolved within sixty (60) days of the first meeting, either Party (by notice to the other Party) may submit the controversy for non-binding mediation pursuant to Section 11.10(d).

(d) Mediation. Either Party may initiate mediation by providing Notice to the other Party in accordance with Section 11.11 of a written request for mediation, setting forth a description of the dispute and the relief requested. The Parties will cooperate with one another in selecting the mediator (“Mediator”) from the panel of neutrals from Judicial Arbitration and Mediation Services, Inc. (“JAMS”), its successor, or any other mutually acceptable non-JAMS Mediator, and in scheduling the time and place of the mediation. Such selection and scheduling will be completed within forty-five (45) days after Notice of the request for mediation. Unless otherwise agreed to by the Parties, the mediation will not be scheduled for a date that is greater than one hundred twenty (120) days from the date of Notice of the request for mediation. The Parties covenant that they will participate in the mediation in good faith, and that they will share equally in its costs (other than each Party’s individual attorneys’ fees and costs related to the Party’s participation in the mediation, which fees and costs will be borne by such Party). All offers, promises, conduct and statements, whether oral or written, made in connection with or during the mediation by either of the Parties, their agents, representatives, employees, experts and attorneys, and by the Mediator or any of the Mediator’s agents, representatives and employees, will not be subject to discovery and will be confidential, privileged and inadmissible

for any purpose, including impeachment, in any arbitration or other proceeding between or involving the Parties, or either of them, provided, evidence that is otherwise admissible or discoverable will not be rendered inadmissible or non-discoverable as a result of its use in the mediation.

(e) Arbitration. Either Party may initiate final and binding arbitration with respect to the matters first submitted to mediation by providing Notice of a demand for binding arbitration before a single, neutral arbitrator (the “Arbitrator”) at any time following the unsuccessful conclusion of the mediation provided for above. The Parties will cooperate with one another in selecting the Arbitrator within sixty (60) days after Notice of the demand for arbitration and will further cooperate in scheduling the arbitration to commence no later than one hundred eighty (180) days from the date of Notice of the demand. To be qualified as an Arbitrator, each candidate must be a retired judge of a trial court of any state or federal court, or retired justice of any appellate or supreme court. Unless otherwise agreed to by the Parties, the individual acting as the Mediator will be disqualified from serving as the Arbitrator in the dispute, although the Arbitrator may be another member of the JAMS panel of neutrals or such other panel of neutrals from which the Parties have agreed to select the Mediator. Upon Notice of a Party’s demand for final and binding arbitration, such dispute submitted to arbitration, including the determination of the scope or applicability of this Agreement to arbitrate, will be determined by final and binding arbitration before the Arbitrator, in accordance with the laws of the State of New Mexico, without regard to principles of conflicts of laws. Except as provided for herein, the arbitration will be conducted by the Arbitrator in accordance with the rules and procedures for arbitration of complex business disputes for the organization with which the Arbitrator is associated. Notwithstanding the rules and procedures that would otherwise apply to the arbitration, and unless the Parties agree to a different arrangement, the place of the arbitration will be Phoenix, Arizona, if arbitration is initiated by Seller, and Los Angeles, California, if arbitration is initiated by Purchaser.

Also notwithstanding the rules and procedures that would otherwise apply to the arbitration, and unless the Parties agree to a different arrangement, discovery will be limited as follows:

(i) Before discovery commences, the Parties shall exchange an initial disclosure of all documents and percipient witnesses which they intend to rely upon or use at any arbitration proceeding (except for documents and witnesses to be used solely for impeachment);

(ii) The initial disclosure will occur within thirty (30) days after the initial conference with the Arbitrator or at such time as the Arbitrator may order;

(iii) Discovery may commence at any time after the Parties’ initial disclosure;

(iv) The Parties will not be permitted to propound any interrogatories or requests for admissions;

(v) Discovery by each Party will be limited to twenty-five (25) document requests (with no subparts), three (3) lay witness depositions, and three (3) expert

witness depositions (unless the Arbitrator holds otherwise following a showing by the Party seeking the additional documents or depositions that the documents or depositions are critical for a fair resolution of the dispute or that a Party has improperly withheld documents);

(vi) Each Party is allowed a maximum of three (3) expert witnesses, excluding rebuttal experts;

(vii) Within sixty (60) days after the initial disclosure, or at such other time as the Arbitrator may order, the Parties shall exchange a list of all experts upon which they intend to rely at the arbitration proceeding;

(viii) Within thirty (30) days after the initial expert disclosure, each Party may designate a maximum of two (2) rebuttal experts;

(ix) Unless the Parties agree otherwise, all direct testimony will be in form of affidavits or declarations under penalty of perjury; and

(x) Each Party shall make available for cross examination at the arbitration hearing its witnesses whose direct testimony has been so submitted.

The Arbitrator will have the authority to grant any form of equitable or legal relief a Party might recover in a court action. The Parties acknowledge and agree that irreparable damage would occur if certain provisions of this Agreement are not performed in accordance with the terms of the Agreement, that money damages would not be a sufficient remedy for any breach of these provisions of this Agreement, and that the Parties shall be entitled, without the requirement of posting a bond or other security, to specific performance and injunctive or other equitable relief as a remedy for a breach of this Agreement. Judgment on the award may be entered in any court having jurisdiction. The Arbitrator must, in any award, allocate all of the costs of the binding arbitration (other than each Party’s individual attorneys’ fees and costs related to the Party’s participation in the arbitration, which fees and costs will be borne by such Party), including the fees of the Arbitrator and any expert witnesses, against the Party who did not prevail; provided that if neither Party prevails completely such costs shall be allocated in favor of the Party who substantially prevailed as determined by the Arbitrator. Until such award is made, however, the Parties will share equally in paying the costs of the arbitration.
