THE CLOSING
 
3.1  ClosingUpon the terms and subject to the satisfaction of the conditions contained in Article VII of this Agreement, the sale and delivery of the CPI Stock and the CEM Membership Interests to Buyer, the payment of the Purchase Price to Seller, and the consummation of the other respective obligations of the Parties contemplated by this Agreement shall take place at a closing (the “Closing”), to be held at the offices of Thelen Reid Brown Raysman & Steiner LLP, 875 Third Avenue, New York, New York at 10:00 a.m. local time, or another mutually acceptable time and location, on the date that is five (5) Business Days (or such later date as may be provided by Section 6.15 hereof) following the date on which the last of the conditions precedent to Closing set forth in Article VII of this Agreement have been either satisfied or waived by the Party for whose benefit such conditions precedent exist or such other date as the Parties may mutually agree. The date of Closing is hereinafter called the “Closing Date.” The Closing shall be effective for all purposes as of 12:01 a.m. on the Closing Date.
 
3.2  Payment of Purchase PriceUpon the terms and subject to the satisfaction of the conditions contained in this Agreement, in consideration of the aforesaid sale, assignment, conveyance, transfer and delivery of the CPI Stock and CEM Membership Interests, Buyer will pay or cause to be paid to Seller at the Closing an aggregate amount of Six Hundred Million United States Dollars (U.S. $600,000,000) subject to adjustment as provided in Section 3.3 (the “Purchase Price”) by wire transfer of immediately available funds denominated in U.S. Dollars or by such other means as are agreed upon by Seller and Buyer, as adjusted pursuant to Section 3.3.
 
3.3  Purchase Price Adjustment.
 
(a)  The Purchase Price is premised upon CEM and CPI having as of the Closing Date and delivering to Buyer an aggregate Working Capital of Zero Dollars ($0) (the “Working Capital Amount”). Accordingly, the Purchase Price shall be (i) increased by the amount, if any, by which the aggregate Working Capital of CEM and CPI as of the Closing Date is greater than the Working Capital Amount, or (ii) decreased by the amount, if any, by which the aggregate Working Capital of CEM and CPI as of the Closing Date is less than the Working Capital Amount. Any such adjustment to the Purchase Price shall be effected in accordance with this Section 3.3 (the “Adjustment”).
 
(b)  Seller agrees to prepare and deliver to Buyer at least five (5) Business Days prior to the Closing Date an unaudited consolidated balance sheet and income statement for each of CEM and CPI reflecting the financial condition of each of CEM and CPI as of the most recent month end prior to the Closing Date, together with a statement setting forth (i) the estimated aggregate Working Capital of CEM and CPI as of the Closing Date and (ii) the Adjustment, if any, pursuant to clauses (i) and (ii) of Section 3.3(a), above (the “Initial Closing Statement”). Within sixty (60) days after the Closing Date, Buyer shall prepare and deliver to Seller an unaudited consolidated balance sheet and income statement reflecting the financial condition of each of CEM and CPI as of the Closing Date, together with a statement setting forth (i) the aggregate Working Capital of CEM and CPI as of the Closing Date and (ii) the Adjustment, if any, pursuant to clauses (i) and (ii) of Section 3.3(a) above (the “Closing Statement”). The Initial Closing Statement and the Closing Statement shall be prepared in a manner consistent with the application of the accounting principles, practices and procedures of the Financial Statements and the provisions of this Agreement.
 
(c)  If the Initial Closing Statement sets forth an aggregate Working Capital of CEM and CPI greater than the Working Capital Amount and a corresponding upward adjustment to the Purchase Price, then the Purchase Price payable on the Closing Date shall be increased by an amount equal to such Adjustment. If the Initial Closing Statement sets forth the aggregate Working Capital of CEM and CPI less than the Working Capital Amount and a corresponding downward adjustment to the Purchase Price, then the Purchase Price payable on the Closing Date shall be decreased by an amount equal to such Adjustment. If the aggregate Working Capital of CEM and CPI as set forth on the Closing Statement is different than that included on the Initial Closing Statement, then (i) to the extent that the Working Capital on the Closing Statement is greater than the Working Capital on the Initial Closing Statement, Buyer shall pay to Seller an amount equal to the absolute value of such difference, and (ii) to the extent that the Working Capital on the Closing Statement is less than the Working Capital on the Initial Closing Statement, Seller shall pay to Buyer an amount equal to the absolute value of such difference, subject to Section 3.3(d) below. In each case, such payment shall be made in cash in immediately available funds within twenty (20) days after the date the Closing Statement becomes final under Section 3.3(d). The Purchase Price shall be deemed to be increased or decreased (as the case may be) by the amounts calculated under this Section 3.3(c). The Parties agree that for Income Tax and all other Tax purposes, the Parties shall and shall cause their Affiliates to calculate and timely report such increase or decrease with respect to CPI and CEM on a separate entity basis. The Parties shall promptly agree upon revisions to all of the allocations prepared pursuant to Section 6.9(a) to reflect such increase or decrease, and the Parties shall and shall cause their Affiliates to not take a position on any Tax Return, with any Tax authority, or otherwise that is inconsistent with such calculations and revised allocations, except to the extent specifically required pursuant to this Agreement.
 
(d)  Each Party shall make available to the other Party its work papers used to prepare its respective closing statement, and shall cooperate with the other Party in connection with the preparation thereof. Seller shall notify Buyer in writing within twenty (20) days after receipt by Seller of the Closing Statement of any objection to the items set forth therein, which notice shall include a reasonably detailed explanation of the reasons for each objection by Seller (an “Objection Notice”), provided, that the Seller may only object to the items contained in the Closing Statement to the extent any such item was not prepared in accordance with this Agreement or contains mathematical errors. Any item not so objected to by Seller shall be conclusively deemed to have been approved by Seller and shall be conclusive and binding upon the Parties. If the Parties are unable to resolve such dispute within thirty (30) days after the date of receipt by Seller of the Closing Statement, then Buyer and Seller shall agree upon and designate an Independent Accounting Firm (the “Designated Independent Accounting Firm”) and the Designated Independent Accounting Firm shall, within fifteen (15) days of its appointment, make a final and binding determination solely of the matters that remain in dispute and were properly included in the Objection Notice, and, based on such resolution, a final and binding determination of the Adjustment amount, if any. If Buyer and Seller are unable to agree upon a Designated Independent Accounting Firm, then each of the Buyer and Seller shall designate one Independent Accounting Firm and the two Independent Accounting Firms so selected shall, within ten (10) days after the date on which the later of the two Independent Accounting Firms are appointed, appoint a third Independent Accounting Firm (the “Third Independent Accounting Firm”) and the Third Independent Accounting firm shall, within fifteen (15) days of its appointment, make a final and binding determination solely of the matters that remain in dispute and were properly included in the Objection Notice, and, based on such resolution, a final and binding determination of the Adjustment amount, if any. The Designated Independent Accounting Firm or the Third Independent Accounting Firm, as the case may be, shall act on the following basis: such Independent Accounting Firm shall act as an expert and not as an arbitrator; its terms of reference shall be to determine the appropriate Adjustment within fifteen (15) days of its appointment, having strict regard to the application of the terms of this Agreement to the same (and, for the avoidance of doubt, disregarding other means of calculating the same, to the extent that such means are inconsistent with or not provided for in this Agreement); Buyer and Seller shall each provide such Independent Accounting Firm with all such information as it reasonably requires and the Independent Accounting Firm shall base its decision solely on such written submissions by Buyer and Seller and their respective representatives; such Independent Accounting Firm shall not hold any hearings, hear any oral testimony or otherwise seek or require any other evidence and it may not assign a value greater than the greatest value for such item claimed by either Party or smaller than the smallest value for such item claimed by either Party. The final written determination of such Independent Accounting Firm shall (in the absence of fraud or manifest error) be conclusive and binding on the Parties. The Independent Accounting Firms shall not have the power to amend or modify any terms of this Agreement. The costs of the Independent Accounting Firms shall be borne pro rata by Seller and Buyer in proportion to the difference between the Designated Independent Accounting Firm’s or the Third Independent Accounting Firm’s, as the case may be, final determination of any Adjustment amount and each of Buyer’s and Seller’s determination of such Adjustment amount. For example, if Buyer calculated an Adjustment amount of $100,000, Seller calculated an Adjustment amount of $50,000 and the Designated Independent Accounting Firm or the Third Independent Accounting Firm, as the case may be, calculated an Adjustment amount of $60,000, Buyer would pay that portion of the Independent Accounting Firms’ fees determined by dividing $40,000 ($100,000 - $60,000) by $50,000 ($100,000 - $50,000) (i.e., 80%) and Seller would pay the remaining 20% of such fees.
 
(e)  Any disputed amounts or any amounts not paid within five (5) days of when due and owing, plus interest thereon at the Default Interest Rate which shall have accrued from the due date until the date of payment, shall be paid in accordance with Section 3.3(c) above within ten (10) days after the date the Designated Independent Accounting Firm or the Third Independent Accounting Firm, as the case may be, provides to both Parties its final written determination pursuant to Section 3(d) above. In addition, any amount not paid within ten (10) days of when due if not disputed in accordance with Section 3.3(d) above shall accrue interest at the Default Interest Rate.
 
(f)  Each of the Parties agrees and undertakes to the other to provide all reasonable access, necessary data and information, and to assist in the calculations referred to in this Section 3.3.
 
3.4  Deliveries by SellerAt the Closing, Seller will deliver, or cause to be delivered, the following to Buyer:

(b)  The CEM ownership ledger marked with appropriate notations evidencing the transfer of the CEM Membership Interests to Buyer;

(m)  Such other agreements, documents, instruments and writings as are required to be delivered by Seller at or prior to the Closing Date pursuant to this Agreement or otherwise reasonably required in connection herewith.
 
3.5  Deliveries by BuyerAt the Closing, Buyer will deliver, or cause to be delivered, the following to Seller:

6.9  Tax Matters.
 
(a)  Section 338(h)(10) Elections.
 
(i)  Seller and Buyer shall jointly make or cause to be made timely and irrevocable elections under Section 338(h)(10) of the Code (the “Election”) with respect to the sale of each of CPI and CEM and the deemed sale of each of the Investor Subsidiaries, the Service Subsidiaries and the Project Companies constituting corporations for federal income Tax purposes, except that no such elections shall be made with respect to Hartwell Power Company (such entities for which elections shall be made, the “338(h)(10) Election Entities”). In addition, Seller and Buyer shall jointly make all elections under state and local Tax law comparable to the elections under Section 338(h)(10) or Section 338(g) as available, unless such state or locality does not have a provision comparable to Section 338(h)(10) or Section 338(g), in which case no election shall be made in such state or locality (together with the Election, the “Section 338(h)(10) Elections”). Seller and Buyer shall and shall cause their respective Subsidiaries and Affiliates to (i) treat the Section 338(h)(10) Elections as valid, (ii) file all Tax Returns in a manner consistent with such Section 338(h)(10) Elections and (iii) take no position contrary thereto. Seller shall be responsible for and shall timely pay or cause to be timely paid to applicable Governmental Authorities all Income Taxes imposed on Seller and all 338(h)(10) Election Entities that are attributable to the making of the Section 338(h)(10) Elections, provided, however, that for any state or local jurisdiction that imposes Income Tax on both the sale (or deemed sale) of the stock of a 338(h)(10) Election Entity and the deemed sale of assets of such 338(h)(10) Election Entity, Seller shall be responsible for only the Income Tax imposed on the sale (or deemed sale) of the stock of such 338(h)(10) Election Entity and Buyer shall be responsible for and shall timely pay or cause to be timely paid to applicable Governmental Authorities all Income Taxes imposed on the deemed sale of assets of such 338(h)(10) Election Entity (such Taxes for which Buyer is responsible, the “Buyer 338 Liability”).
 
(ii)  Prior to the Closing, Buyer shall (A) determine the amount of the adjusted grossed-up basis and aggregate deemed sales price with respect to each of the 338(h)(10) Election Entities and the allocation of such amounts among the assets of each of the 338(h)(10) Election Entities on a separate entity basis in accordance with Section 338(h)(10) of the Code and applicable Treasury Regulations thereunder and (B) deliver a schedule of all such determinations to Seller and provide Seller with a reasonable opportunity to review, comment on, and consent to such schedule prior to the Closing, which consent shall not be unreasonably withheld or delayed (the “338 Allocation”). Buyer shall promptly revise the 338 Allocation to reflect the Adjustment, as finally determined pursuant to Section 3.3 of the Agreement and Buyer shall promptly forward a draft of the revised 338 Allocation to Seller for Seller’s consent, which consent shall not be unreasonably withheld or delayed. Seller and Buyer shall take, and shall cause their respective Affiliates to take, no action inconsistent with, or fail to take any action necessary for the validity of each Section 338(h)(10) Election, and shall adopt and utilize, and cause their respective Affiliates to adopt and utilize, the asset values prescribed in the 338 Allocation (as revised by Seller and Buyer) in making such allocations for the purpose of all Tax Returns filed by them, and shall not voluntarily take any action inconsistent therewith upon examination of any Tax Return, in any refund claim, in any litigation or otherwise with respect to such Tax Returns. Buyer and Seller shall notify and provide the other with reasonable assistance in the event of an examination, audit or other proceeding regarding the agreed upon allocations.
 
(iii)  The Purchase Price allocable to Hartwell Independent Power Partners, Inc. and Hart County IPP, Inc. and the share of each such entity of the liabilities of the Hartwell Partnership shall be allocated among the assets of the Hartwell Partnership as of the Closing Date in accordance with a schedule to be prepared in accordance with the rules under Code Sections 743(b), 751, 755 and 1060 (the “754 Allocation Schedule”). Buyer shall deliver a draft of the 754 Allocation Schedule to Seller and the Hartwell Partnership as soon as practicable after the date of this Agreement, and Buyer, Seller and the Hartwell Partnership shall mutually agree upon the 754 Allocation Schedule at or prior to the Closing. Buyer and Seller shall not, and Seller shall use all Commercially Reasonable Efforts to cause the Hartwell Partnership to not, unreasonably withhold its approval and consent with respect to the 754 Allocation Schedule. Buyer and Seller agree that the 754 Allocation Schedule shall be amended to reflect any post-Closing adjustments to the allocation that are required by applicable federal income Tax law. Unless otherwise required by applicable law, Buyer and Seller agree to act, and to cause their Affiliates and the Hartwell Partnership to act, in accordance with the computations and allocations contained in the 754 Allocation Schedule (taking into account any such amendment thereto) in any relevant Tax Returns or similar filings (including forms or reports, if any, required to be filed pursuant to Code Section 1060), to cooperate in the preparation of any such filings, to timely file such filings in the manner required by applicable law and to not take any position inconsistent with such 754 Allocation Schedule in any Tax Return, in any refund claim, in any litigation, or otherwise.
 
(b)  Return Filing, Payments, Refunds and Credits.
 
(i)  Seller shall prepare or cause to be prepared and file or cause to be filed all Federal, state and local Tax Returns for (x) CEM, CPI, the Investor Subsidiaries, the Service Subsidiaries and the Project Companies (other than Hartwell Partnership) (the “Target Entities”) for all Pre-Closing Tax Periods of such entities, including the consolidated federal income Tax Return of MDU Resources Group, Inc. for the Tax period ending on December 31, 2007, and (y) any Affiliated Group that includes any of the Target Entities (other than an Affiliated Group that has no members other than two or more of the Target Entities) (an “MDU Affiliated Group”). Each such Tax Return shall be prepared in a manner consistent with past practice. Buyer shall not, and shall cause its Affiliates not to, amend, refile, modify or revoke such Tax Returns (or any notification or election relating thereto) without the prior written consent of Seller, which consent shall not be unreasonably withheld or delayed; provided, for the avoidance of doubt, that the Seller shall be deemed to have reasonably withheld its consent if any such action by Buyer or its Affiliates could reasonably be expected to have an adverse impact upon any Taxes or Tax Returns (or Tax attribute) of Seller or any of its Affiliates for any Tax period ending on or prior to the Closing Date or any Straddle Period. Buyer and Seller shall act in good faith to resolve any disputes, but in the event Buyer and Seller do not resolve any disputed items by agreement, either Buyer or Seller may refer such dispute to an Independent Accounting Firm for resolution, and the decision of the Independent Accounting Firm shall be final and binding on Buyer and Seller and their respective Affiliates. The costs, expenses and fees of the Independent Accounting Firm shall be borne equally by Seller, on the one hand, and Buyer, on the other hand. Buyer shall and shall cause its Affiliates to timely provide Seller with all information as Seller shall reasonably request in connection with the preparation of such Tax Returns. Seller and its Affiliates shall be responsible for payment of any Income Taxes, and shall be entitled to any refunds or credits of Income Taxes, shown as due on such Tax Returns, except that Buyer and its Affiliates shall be responsible for the timely payment of any Buyer 338 Liability and any Income Taxes resulting from any transaction or event that is not in the ordinary course of business and occurs after the Closing on the Closing Date. Buyer shall timely pay or cause to be timely paid all Taxes (other than Income Taxes) shown as due on such Tax Returns. The income or loss or other items to be reported on the federal income Tax Return to be filed for CEM, CPI, the Investor Subsidiaries, the Service Subsidiaries and the Project Companies (other than the Hartwell Partnership) for the period that began on January 1, 2007 and ends on the Closing Date shall be based upon a closing of the books as of the close of business on the Closing Date, consistent with Treasury Regulation Section 1.1502-76(b). Buyer and Seller shall use Commercially Reasonable Efforts to cause the Investor Subsidiaries’ distributive shares of the income or loss of the Hartwell Partnership for the fiscal year that includes the Closing Date to be reported in the Tax Return described in the preceding sentence and determined based upon a hypothetical closing of the books of Hartwell Partnership as of the Closing Date, consistent with Treasury Regulation Section 1.1502-76(b)(2)(vi)(A). Notwithstanding anything in this Agreement to the contrary, Buyer and Seller agree that all transactions and events in respect of any of the Target Entities and the Hartwell Partnership that are not in the ordinary course of business and occur after the Closing on the Closing Date shall be reported on the Tax Return(s) of Buyer and its Affiliates to the extent required or permitted by Treasury Regulation section 1.338-1(d) or 1.1502-76(b)(1)(ii)(B) or other applicable federal or state Tax law.
 
(ii)  Buyer shall, except to the extent that such Tax Returns are the responsibility of Seller under Section 6.9(b)(i), timely prepare and file or cause to be timely prepared and filed all Tax Returns of CEM, CPI, the Investor Subsidiaries, the Service Subsidiaries and the Project Companies (other than Hartwell Partnership). For any Straddle Period Tax Return that is the responsibility of Buyer under this Section 6.9(b)(ii), Buyer shall, and shall cause its Affiliates to, prepare such Tax Return in a manner consistent with past practices and with all Tax Returns prepared or caused to be prepared by Seller pursuant to Section 6.9(b)(i) with respect to the entity in question, and Buyer shall deliver to Seller for its review, comment and approval (which approval shall not be unreasonably withheld) a copy of each such proposed Tax Return (accompanied, in the case of each Income Tax Tax Return, by an allocation of the Income Taxes shown to be due on such Tax Return between the portion of such Straddle Period ending on the Closing Date and the portion of such Straddle Period beginning after the Closing Date) at least thirty Business Days prior to (a) the due date for filing such Tax Return (giving effect to any validly obtained extensions), or (b) if there is no due date for filing, the actual filing date thereof. Buyer shall and shall cause its Affiliates to not unreasonably fail to reflect any comments received from Seller. Buyer shall timely pay or cause to be timely paid all Taxes shown as due on such Tax Returns. Seller shall reimburse Buyer for Income Taxes shown to be due on such Tax Returns as filed, to the extent allocable to the portion of such Straddle Period ending on the Closing Date, and Buyer shall promptly pay to Seller the amount of Income Taxes allocable to the portion of such Straddle Period beginning after the Closing Date to the extent such Income Taxes were paid on or prior to the Closing Date. Buyer shall promptly pay to Seller the amount of any refunds or credits of Income Taxes allocable to the portion of such Straddle Period ending on the Closing Date. For purposes of this Agreement, in the case of any Straddle Period, Income Taxes allocable to the portion of such Straddle Period ending on the Closing Date shall be computed as if the Tax period ended on the Closing Date, except that any Buyer 338 Liability and any Income Taxes resulting from any transaction or event that is not in the ordinary course of business and occurs after the Closing on the Closing Date shall be allocable to the portion of such Straddle Period beginning after the Closing Date. Buyer shall not, and shall cause its Affiliates to not, amend, refile, modify or revoke any Straddle Period Tax Return (or any notification or election relating thereto) without the prior written consent of Seller, which consent shall not be unreasonably withheld; provided, for the avoidance of doubt, that the Seller shall be deemed to have reasonably withheld its consent if any such action by Buyer or its Affiliates could reasonably be expected to have an adverse impact upon any Taxes or Tax Returns (or Tax attribute) of Seller or any of its Affiliates for any Tax period ending on or prior to the Closing Date or any Straddle Period. Buyer and Seller shall act in good faith to resolve any disputes, but in the event Buyer and Seller do not resolve any disputed items by agreement, either Buyer or Seller may refer such dispute to an Independent Accounting Firm for resolution, and the decision of the Independent Accounting Firm shall be final and binding on Buyer and Seller and their respective Affiliates. The costs, expenses and fees of the Independent Accounting Firm shall be borne equally by Seller, on the one hand, and Buyer, on the other hand.
 
(iii)  Seller and its Affiliates shall be entitled to any refunds or credits of or against any Excluded Taxes and any other Taxes for which Seller or its Affiliates are responsible pursuant to this Agreement. Buyer shall, at Seller's reasonable request, file or cause the relevant entity to file for and use Commercially Reasonable Efforts to obtain any refund or credit to which Seller and its Affiliates are entitled.
 
(iv)  Buyer shall, and shall cause its Affiliates to, promptly forward to Seller and its Affiliates or reimburse Seller and its Affiliates for any refunds or credits of Taxes due Seller and its Affiliates (pursuant to the terms of this Section 6.9) after receipt thereof.
 
(v)  Buyer shall, and shall cause its Affiliates to, elect, where permitted by applicable law, to carry forward any item of loss, deduction or credit which arises in any Tax period beginning after the Closing Date.
 
(c)  Cooperation on Tax Matters.
 
(i)  Buyer and Seller shall (and each shall cause CEM, CPI, the Investor Subsidiaries, the Service Subsidiaries and the Project Companies to) cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the preparation and filing of Tax Returns pursuant to this Section and in connection with any audit, litigation or other proceeding with respect to Taxes for any Tax period ending on or prior to the Closing Date. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information which are reasonably relevant to any such audit, litigation or other proceeding and making employees (to the extent such employees were responsible for the preparation, maintenance or interpretation of information and documents relevant to Tax matters or to the extent required as witnesses in any Tax proceedings), available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Parties agree (A) to retain, and (in the case of Buyer) to cause CEM, CPI, the Investor Subsidiaries, the Service Subsidiaries and the Project Companies to retain, all books and records with respect to Income Tax matters pertinent to CEM, CPI, the Investor Subsidiaries, the Service Subsidiaries and the Project Companies relating to any Tax period beginning before the Closing Date until six months after the expiration of the statute of limitations (and, to the extent notified by Buyer or Seller, any extensions thereof) of the respective Tax periods, and to abide by all record retention obligations imposed by law or pursuant to agreements entered into with any taxing authority, and (B) to give the other Party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other Party so requests, Buyer or Seller, as the case may be, shall allow the other Party to take possession of such books and records.
 
(ii)  Buyer and Seller further agree, upon request, to use their best efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed with respect to the transactions contemplated hereby.
 
(iii)  At Seller's request, Buyer shall cause CEM, CPI, the Investor Subsidiaries, the Service Subsidiaries and the Project Companies to make and/or join with Seller and any of Seller’s Affiliates in making after Closing any election for which such entity’s consent is required for any Tax period (or portion thereof) ending on or prior to the Closing Date, if the making of such election does not have a material adverse impact on Buyer (or any of its Affiliates) for any Tax period beginning after the Closing Date.
 
(d)  Contests.
 
(i)  Seller and Buyer shall notify the other Party in writing within fourteen (14) days or such shorter period as may be required thereby of receipt by it or any of its Affiliates of written notice of any pending or threatened Tax examination, audit or other administrative or judicial proceeding (a “Tax Contest”) that could reasonably be expected to result in an indemnification obligation of such other Party pursuant to this Agreement and such timely notice shall specify in reasonable detail the basis for any claim included therein and shall include a copy of the relevant portion of any correspondence received from the taxing authority. If the recipient of such notice of a Tax Contest fails to provide such timely notice to such other Party, it shall not be entitled to indemnification for any Taxes arising in connection with such Tax Contest, but only to the extent, if any, that such failure or delay shall have adversely affected the indemnifying Party’s ability to defend against, settle, or satisfy any action, suit or proceeding against it, or any damage, loss, claim, or demand for which the indemnified Party is entitled to indemnification hereunder, and the indemnifying Party’s indemnity obligations shall be reduced to the extent of any Tax or other liability incurred as a result of the delay or failure to receive such timely notice.
 
(ii)  If a Tax Contest relates to any Taxes for which Seller is liable in full hereunder, Seller shall at its expense control the defense and settlement of such Tax Contest. If such Tax Contest relates to any Taxes for which Buyer is liable in full hereunder, Buyer shall at its own expense control the defense and settlement of such Tax Contest. The Party not in control of the defense shall have the right to observe the conduct of any Tax Contest at its expense, including through its own counsel and other professional experts. Buyer and Seller shall jointly represent CEM, CPI, any Investor Subsidiary, any Service Subsidiary or any Project Company in any Tax Contest relating to Taxes for which both are liable hereunder, and fees and expenses related to such representation shall be paid equally by Buyer and Seller.
 
(iii)  Notwithstanding anything to the contrary in Section 6.9(d)(ii), to the extent that an issue raised in any Tax Contest controlled by one Party or jointly controlled could materially affect the liability for Taxes of the other Party, the controlling Party shall not, and neither Party in the case of joint control shall, enter into a final settlement without the consent of the other Party, which consent shall not be unreasonably withheld. Where a Party reasonably withholds its consent to any final settlement, that Party may continue or initiate further proceedings, at its own expense, and the liability of the Party that wished to settle (as between the consenting and the non-consenting Party) shall not exceed the liability that would have resulted from the proposed final settlement including interest, additions to Tax, and penalties that have accrued at that time, and the non-consenting Party shall indemnify the consenting Party for any liability in excess of liability that would have resulted from the proposed final settlement.
 
(iv)  Notwithstanding any other provision of this Agreement to the contrary, if a Tax Contest results in an increase in Income Taxes for which Seller is liable hereunder and such increase is attributable to adjustments based on timing differences which will reverse in Tax periods ending subsequent to the Closing Date, Buyer shall promptly pay to Seller, upon Seller's written request, an amount equal to the present value of the reduction in Income Taxes payable by the Buyer and its Affiliates in future Tax periods by reason of such reversal, determined by using a discount rate of 6% and an assumed Tax rate of 40%, and by assuming that such reduction in Income Taxes will occur in the year or years of reversal.
 
(e)  Tax Sharing Agreements. Any Tax sharing agreement or similar arrangement between Seller or any Affiliate of Seller (other than CEM, CPI, the Investor Subsidiaries, the Service Subsidiaries and the Project Companies) on the one hand, and any of CEM, CPI, the Investor Subsidiaries, the Service Subsidiaries or the Project Companies on the other hand shall be terminated with respect to CEM, CPI, the Investor Subsidiaries, the Service Subsidiaries and the Project Companies, as applicable, as of the Closing Date.
 
(f)  Certain Taxes. Notwithstanding anything in this Agreement to the contrary, all transfer, documentary, sales, use, stamp, registration and other such Taxes and fees (including any penalties and interest) incurred in connection with this Agreement, whether imposed upon Seller, Buyer, CEM, CPI, any Investor Subsidiary, any Service Subsidiary or any Project Company (“Transfer Taxes”), shall be borne 50 percent by Seller and 50 percent by Buyer. Seller and Buyer shall, and shall cause their respective Affiliates, to prepare and timely file all necessary Tax Returns and other documentation with respect to all such Transfer Taxes, and, if required by applicable law, Buyer shall, and shall cause CEM, CPI, the Investor Subsidiaries, Service Subsidiaries and Project Companies to, join in the execution of all such Tax Returns and other documentation. All costs and expenses incurred in connection with the filing of all such Tax Returns and documentation hereunder shall be borne by Buyer.
 
(g)  Disputes. In the event that a dispute arises between Seller and Buyer as to the amount of Taxes, or indemnification, whether or not attributable to CEM or CPI, the Parties shall attempt in good faith to resolve such dispute, and any agreed upon amount shall be paid to the appropriate Party. If such dispute is not resolved thirty (30) days thereafter, the Parties shall submit the dispute to an Independent Accounting Firm mutually appointed by Seller and Buyer 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 Buyer. 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.
 
(h)  Alternative Structure. The Parties agree to discuss in good faith alternative structures to complete the transactions contemplated by this Agreement, but Buyer acknowledges that (x) no such alternatives shall delay the Closing Date or increase the risks or costs of the transactions to Seller or decrease the net after-tax proceeds received by Seller from the transactions and (y) that Seller shall have no obligation to agree to any such alternative structure.
 
6.10  Advice of ChangesPrior to the Closing, each Party will promptly advise the other in writing with respect to any matter arising after execution of this Agreement of which that Party obtains knowledge and which, if existing or occurring at the date of this Agreement, would have been required to be set forth in this Agreement, including any of the Schedules hereto, or of any breach of any representation or warranty or of any other condition or circumstance that would excuse a Party of timely performance of its obligations hereunder. Subject to Buyer’s consent, Seller may cause CEM, CPI, the Investor Subsidiaries, the Service Subsidiaries or the Project Companies to amend, substitute or otherwise modify any CEM Agreement, CPI Agreement or Project Contract to the extent that any such agreement expires by its terms prior to the Closing Date. Nothing contained herein shall relieve Seller or Buyer of any breach of representation, warranty or covenant under this Agreement existing as of the date hereof or any subsequent date as of which such representation, warranty or covenant shall have been made; provided, however, that Seller shall have no liability to Buyer for any breach of any representation, warranty or covenant hereunder which results from Buyer withholding its consent under the immediately preceding sentence. Notwithstanding the foregoing, Seller shall be entitled to cause BIV Generation and Brush Power, LLC to enter into the Replacement PPA subject to Section 6.1(b) hereof.
 
6.11  Consents.  Seller shall use Commercially Reasonable Efforts to obtain all consents and approvals for the consummation of the transactions contemplated hereby required under any CEM Agreement, CPI Agreement or Major Project Contract, and all required waivers of any rights of first refusal, rights of first offer, or similar preemptive rights with respect to any of the Project Company Interests necessary in order to consummate the transactions contemplated by this Agreement.
 
6.12  Buyer Financial Assurance. Simultaneous with the execution and delivery of this Agreement, Buyer is providing to Seller (a) an irrevocable standby letter of credit from Barclays Bank PLC in the stated amount of $50 million (the “Buyer LC”) which shall permit, subject to the terms and conditions of this Agreement, Seller to draw up to $50 million in payment of the Termination Fee, and (b) an equity commitment letter (the “Equity Commitment Letter”) from Natural Gas Partners VIII L.P. dated the date hereof, addressed to Buyer confirming the commitment and availability of not less than $120 million, which funds will be provided to Buyer on or before the Closing Date in order to fund a portion of the payment of the Purchase Price.
 
6.13  Financing Cooperation.  At Buyer’s request, Seller shall, and shall use its reasonable efforts to cause CEM, CPI and their respective Subsidiaries to, provide reasonable cooperation with Buyer and Buyer’s lenders in connection with Buyer obtaining debt financing for the consummation of the transactions contemplated hereby, including making representatives of such parties available at reasonable times in connection with the syndication of such debt financing and related activities.

(a)  Except as specifically provided in this Section 6.14, Seller shall, and shall cause, CEM, CPI, the Investor Subsidiaries, the Service Subsidiaries and the Project Companies to take all necessary actions, including compliance with all applicable Laws, such that (i) immediately prior to the Closing, none of these entities shall sponsor, maintain, participate in, contribute to or have an obligation to contribute to any Benefit Plan or Benefit Agreement on or after the Closing, and (ii) Seller shall retain all Liabilities with respect to the Benefit Plans and Benefit Agreements, including but not limited to liability for all employer contributions required to be made to a Benefit Plan which is a cash or deferred arrangement qualified under Section 401(a) and 401(k) of the Code. As of the Closing Date, Buyer shall waive all pre-existing condition limitations under Buyer’s health care plan for employees continuing in employment with Buyer on and after the Closing Date (“Continuing Employees”) and covered by the health care plan in which CEM, CPI, the Investor Subsidiaries, Service Subsidiaries and any of the Project Companies participated immediately prior to the Closing Date (the “Seller Health Plan”), and shall provide such health care coverage substantially similar in the aggregate to the Seller Health Plan effective as of the Closing Date without the application of any eligibility period for coverage. In addition, with respect to Continuing Employees, Buyer shall cause its health care plan to credit all employee payments toward deductible and co-payment obligations limits under the Seller Health Plan for the plan year that includes the Closing Date as if such payments had been made for similar purposes under Buyer’s health care plan during the plan year that includes the Closing Date.
 
(b)  Notwithstanding the provisions of Section 6.14(a), Seller shall spin-off and transfer all of the obligations and liabilities of any Benefit Plan that is a Section 125 flexible spending plan (the “Seller 125 Plan”) attributable to employees of CPI and CEM and their dependents and beneficiaries to a Section 125 flexible spending plan to be established by CEM (the “New 125 Plan”) immediately prior to the Closing Date, and the New 125 Plan shall credit each such employee's flexible spending account with the balance so transferred. Each employee eligible to participate in the New 125 Plan shall be permitted to continue his or her election in effect under the New 125 Plan for the remainder of the calendar year in which the Closing shall occur, subject to the limitation on contributions contained in the Seller 125 Plan, and CEM shall honor any such election, and the New 125 Plan shall honor (and shall be solely liable for) any claims incurred by an employee in the calendar year, which would otherwise be an eligible expense under the Seller 125 Plan, whether or not such expense was incurred before, on or after the Closing Date. Seller shall provide Buyer with all information reasonably requested by Buyer in order for CEM and the New 125 Plan to satisfy the obligations set forth in this Section 6.14(b). As soon as administratively practicable following the Closing Date, Seller shall pay to Buyer the balance of CPI and CEM employees’ accounts under the Seller 125 Plan; provided, however, that if the balance of CPI and CEM employees’ accounts under the Seller 125 Plan is less than zero, Buyer shall pay to Seller the amount by which such balance is less than zero.
 
(c)  Notwithstanding the provisions of Section 6.14(a), as soon as practicable following the Closing Date, Seller shall fully vest the account balances of each CPI and CEM employee who is a participant in the Benefit Plan that is a 401(k) plan (the “Seller 401(k) Plan”) and shall offer each such participant the opportunity to rollover such participant’s account balance to a defined contribution 401(k) plan established or maintained by Buyer or CEM that is a qualified tax or deferred arrangement under Code Sections 401(a) and 401(k). Such rollover shall be in the form of a direct rollover in accordance with Section 401(a)(31) of the Code and other applicable provisions of ERISA and the Code and shall include the opportunity for participants to rollover all participant loan accounts and liabilities under the Seller 401(k) Plan.
 
6.15  Audited Financial Statements.  Seller shall deliver to Buyer the audited balance sheet, income statement and statement of cash flows of CEM and CPI as of and for the year ended December 31, 2006, (which audited financial statements shall not vary in any material respect from the Financial Statements), as promptly as possible, but in no event later than one (1) Business Day after such audited financial statements are available. Seller agrees that Buyer may, upon written request, postpone the Closing Date by one day for each day beyond May 1, 2007 that Buyer has not received such audited financial statements.
 
6.16  Hartwell Partnership Distributions.  Promptly (but in any event not later than three (3) Business Days) after Buyer’s receipt thereof, Buyer shall remit to Seller by wire transfer in immediately available funds, Seller’s share of Hartwell Partnership distributions or payments with respect to or to the extent allocable to all periods prior to the Closing Date. The Parties agree that Seller’s allocable share of such distributions or payments shall be based on the number of days of Seller’s indirect ownership of the Hartwell Partnership during the period to which such distribution or payment relates divided by the total number of days during such period.

(e)  Except to the extent otherwise provided in Article IX, the rights and remedies of Seller and Buyer under this Article VIII are exclusive and in lieu of any and all other rights and remedies which Seller and Buyer may have under this Agreement or otherwise for monetary relief, with respect to (i) any breach of or failure to perform any covenant, agreement, or representation or warranty set forth in this Agreement, after the occurrence of the Closing, or (ii) liabilities of CEM or CPI being assumed by Buyer or the Excluded Liabilities, as the case may be; provided, however, that the provisions of this Section 8.1(e) shall not prevent or limit (i) a claim of, or a cause of action arising from, fraud or (ii) a cause of action to obtain equitable remedies.

8.2  Defense of Claims.
 
(a)  If any Indemnitee receives notice of the assertion of any claim or of the commencement of any claim, action, or proceeding made or brought by any Person who is not a party to this Agreement or any Affiliate of a Party to this Agreement (a “Third Party Claim”) with respect to which indemnification is to be sought from an Indemnifying Party, the Indemnitee shall give such Indemnifying Party reasonably prompt written notice thereof, but in any event such notice shall not be given later than ten (10) calendar days after the Indemnitee’s receipt of written notice of such Third Party Claim. Such notice shall describe the nature of the Third Party Claim in reasonable detail and shall indicate the estimated amount, if practicable, of the Indemnifiable Loss that has been or may be sustained by the Indemnitee. The Indemnifying Party will have the right to participate in or, by giving written notice to the Indemnitee, to elect to assume the defense of any Third Party Claim at such Indemnifying Party’s expense and by such Indemnifying Party’s own counsel, provided that the counsel for the Indemnifying Party who shall conduct the defense of such Third Party Claim shall be reasonably satisfactory to the Indemnitee. The Indemnitee shall cooperate in good faith in such defense at such Indemnitee’s own expense. If an Indemnifying Party elects not to assume the defense of any Third Party Claim, the Indemnitee may compromise or settle such Third Party Claim over the objection of the Indemnifying Party, which settlement or compromise shall conclusively establish the Indemnifying Party’s liability pursuant to this Agreement.
 
(b)  If, within ten (10) calendar days after an Indemnitee provides written notice to the Indemnifying Party of any Third Party Claims, the Indemnitee receives written notice from the Indemnifying Party that such Indemnifying Party has elected to assume the defense of such Third Party Claim as provided in Section 8.2(a), the Indemnifying Party will not be liable for any legal expenses subsequently incurred by the Indemnitee in connection with the defense thereof for so long as the Indemnifying Party shall continue the diligent defense of such Third Party Claim. Without the prior written consent of the Indemnitee, the Indemnifying Party shall not enter into any settlement of any Third Party Claim which would lead to liability or create any financial or other obligation or restriction on the part of the Indemnitee. If a firm offer is made to settle a Third Party Claim would not lead to liability or the creation of a financial or other obligation or restriction on the part of the Indemnitee and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party shall give written notice to the Indemnitee to that effect. If the Indemnitee fails to consent to such firm offer within ten (10) calendar days after its receipt of such notice, the Indemnifying Party shall be relieved of its obligations to defend such Third Party Claim and the Indemnitee may contest or defend such Third Party Claim. In such event, the maximum liability of the Indemnifying Party as to such Third Party Claim will be the amount of such settlement offer plus reasonable costs and expenses paid or incurred by Indemnitee up to the date of said notice.
 
(c)  Any claim by an Indemnitee on account of an Indemnifiable Loss which does not result from a Third Party Claim (a “Direct Claim”) shall be asserted by giving the Indemnifying Party reasonably prompt written notice thereof, stating the nature of such claim in reasonable detail and indicating the estimated amount, if practicable, but in any event such notice shall not be given later than ten (10) calendar days after the Indemnitee becomes aware of such Direct Claim, and the Indemnifying Party shall have a period of thirty (30) calendar days within which to respond to such Direct Claim. If the Indemnifying Party does not respond within such thirty (30) calendar day period, the Indemnifying Party shall be deemed to have accepted such claim. If the Indemnifying Party fails to accept such claim, the Indemnitee will be free to seek enforcement of its right to indemnification under this Agreement.
 
(d)  If the amount of any Indemnifiable Loss, at any time subsequent to the making of an indemnity payment in respect thereof, is reduced by recovery, settlement or otherwise under or pursuant to any insurance coverage, or pursuant to any claim, recovery, settlement or payment by, from or against any other entity, the amount of such reduction, less any costs, expenses or premiums incurred in connection therewith (together with interest thereon from the date of payment thereof at the publicly announced prime rate then in effect as published in the Wall Street Journal shall promptly be repaid by the Indemnitee to the Indemnifying Party.
 
(e)  A failure to give timely notice as provided in this Section 8.2 shall not affect the rights or obligations of any Party hereunder except if, and only to the extent that, as a result of such failure, the Party which was entitled to receive such notice was actually prejudiced as a result of such failure.
 
(f)  Notwithstanding the foregoing, the Parties agree and acknowledge that (i) Seller shall be entitled exclusively to control, defend and settle any litigation, administrative or regulatory proceeding arising out of or related to any Excluded Liabilities, and Buyer agrees to cooperate fully at Seller’s expense in connection therewith and (ii) Buyer shall be entitled exclusively to control, defend and settle any litigation, administrative or regulatory proceeding, arising out of or related to any Guarantee Liabilities, and Seller agrees to cooperate fully at Buyer’s expense in connection therewith.
 
8.3  SurvivalThe representations and warranties given or made by any Party to this Agreement or in any certificate or other writing furnished in connection herewith shall survive the Closing for a period of 575 days after the Closing Date and shall thereafter terminate and be of no further force or effect, except that (i) the Seller Fundamental Representations and the Buyer Fundamental Representations shall survive indefinitely, (ii) all representations and warranties relating to Sections 4.11 and 4.20(h) shall survive the Closing for a period of thirty (30) days following the applicable statutes of limitation taking into account any extensions or waivers thereof, and (iii) the representations and warranties in Section 4.20(n) shall survive the Closing for a period of 36 months after the Closing Date.
 
The covenants and obligations of Seller and Buyer set forth in this Agreement, including without limitation the indemnification obligations of the Parties under Article VIII hereof, shall survive the Closing indefinitely, and each Party shall be entitled to the full performance thereof by the other Party hereto without limitation as to time or amount (except as otherwise specifically set forth herein).

(b)  This Agreement may be terminated by Seller or Buyer if (i) any Federal or state court of competent jurisdiction shall have issued an order, judgment or decree permanently restraining, enjoining or otherwise prohibiting the Closing, and such order, judgment or decree shall have become final and nonappealable or (ii) any statute, rule, order or regulation shall have been enacted or issued by any Governmental Authority which, directly or indirectly, prohibits the consummation of the Closing; or (iii) the Closing contemplated hereby shall have not occurred on or before the day which is 120 days from the date of this Agreement (the “Termination Date”), provided, however, that so long as such Party has complied with Section 6.5 of this Agreement, the Termination Date (x) may be extended by Buyer for up to thirty (30) days if any of Buyer Required Regulatory Approvals shall not have been obtained and (y) may be extended by Seller for up to thirty (30) days if any of Seller Required Regulatory Approvals shall not have been obtained; and provided, further, that the right to terminate this Agreement under this Section 9.1(b)(iii) shall not be available to any Party whose failure to fulfill any obligation under this Agreement has been the cause of, or resulted in, the failure of the Closing to occur on or before such date.
 
(c)  So long as such Party has complied with Section 6.5 of this Agreement, this Agreement may be terminated by Buyer if any of Buyer Required Regulatory Approvals, the receipt of which is a condition to the obligation of Buyer to consummate the Closing as set forth in Section 7.1(c), shall have been denied (and a petition for rehearing or refiling of an application initially denied without prejudice shall also have been denied) or shall have been granted but contains terms or conditions which do not satisfy the closing condition in Section 7.1(c).
 
(d)  So long as such Party has complied with Section 6.5 of this Agreement, this Agreement may be terminated by Seller, if any of Seller’s Required Regulatory Approvals, the receipt of which is a condition to the obligation of Seller to consummate the Closing as set forth in Section 7.2(c), shall have been denied (and a petition for rehearing or refiling of an application initially denied without prejudice shall also have been denied) or shall have been granted but contains terms or conditions which do not satisfy the closing condition in Section 7.2(c).
 
(e)  This Agreement may be terminated by Buyer if there has been a material violation or breach by Seller of any covenant, representation or warranty contained in this Agreement which has resulted in a Material Adverse Effect and such violation or breach is not cured by the earlier of the Closing Date or the date thirty (30) days after receipt by Seller of notice specifying particularly such violation or breach, and such violation or breach has not been waived by Buyer.
 
(f)  This Agreement may be terminated by Seller, if there has been a material violation or breach by Buyer of any covenant, representation or warranty contained in this Agreement and such violation or breach is not cured by the earlier of the Closing Date or the date thirty (30) days after receipt by Buyer of notice specifying particularly such violation or breach, and such violation or breach has not been waived by Seller.
 
(g)  This Agreement may be terminated by Seller if either the Equity Commitment Letter or the Buyer LC shall no longer remain in full force and effect.
 
9.2  Procedure and Effect of No-Default TerminationIn the event of termination of this Agreement by either or both of the Parties pursuant to Section 9.1, written notice thereof shall forthwith be given by the terminating Party to the other Party, whereupon, if this Agreement is terminated pursuant to any of Sections 9.1(a) through (d), the liabilities of the Parties hereunder will terminate, except as otherwise expressly provided in this Agreement, and thereafter neither Party shall have any recourse against the other by reason of this Agreement.
 
9.3  Termination Fee; Letter of CreditSeller may immediately draw upon the Buyer LC in an amount equal to $50 million (the “Termination Fee”) if this Agreement is terminated by Seller pursuant to Sections 9.1(b)(iii), 9.1(f) or 9.1(g); provided, that Seller shall not be in breach of this Agreement in such a manner that would entitle Buyer to terminate this Agreement in accordance with Section 9.1(e), and provided further, that in the case of termination pursuant to Section 9.1(b)(iii), the failure of the Closing Date to occur was due to the breach by Buyer of its obligations to complete the transactions contemplated hereby when required to do so in accordance with this Agreement. The Parties acknowledge and agree that if Seller shall terminate this Agreement as provided immediately above, Seller’s damages would be difficult or impossible to quantify with reasonable certainty, and accordingly the payment provided for in this Section 9.3 is a payment of liquidated damages (and not penalties) which is a based on the Parties’ estimate of the damages Seller will suffer or incur as a result of the event giving rise to such payment and the resultant termination of this Agreement. Buyer irrevocably waives any right it may have to raise as a defense that any such liquidated damages are excessive or punitive. For greater certainty, the Parties agree that the right to receive payment of the amount determined pursuant to this Section 9.3 in the manner provided herein is the sole and exclusive remedy of Seller. There shall be no liability of any shareholder, partner, member, director, officer, employee, advisor or representative of Buyer or Seller or any Affiliate thereof, whether to Buyer or Seller, as the case may be, or any other Person (including any shareholder, partner, member, director, officer, employee, advisor or representative thereof) in connection with any liability or other obligation of Buyer or Seller or any Affiliate thereof, whether hereunder or otherwise in connection with the transactions contemplated hereby.
