PURCHASE AND SALE AND CLOSING

Section 2.1 Purchase and Sale. On the terms and subject to the conditions set forth in this Agreement:

(a) Seller agrees to cause Newington Energy to exercise the Sale Right so as to become entitled to purchase the Project in accordance with Section 13 of the Lease on the first Basic Rent Payment Date in 2008.

(b) Simultaneously with the Project Purchase, Seller agrees to sell and convey to Buyer, and Buyer agrees to purchase and accept from Seller, all of the Membership Interests. In exchange for the Membership Interests, Buyer shall pay the Purchase Price, as contemplated below.

Section 2.2 Purchase Price. The purchase price (the “Purchase Price”) for the Membership Interests shall be an amount equal to:

(a) $736,000,000.00 (the “Base Purchase Price”); plus

(b) the Net Working Capital Adjustment Amount (whether a positive or a negative amount); minus

Section 2.3 Closing.

(a) Seller shall inform Buyer no later than 12 noon New York City time on the fifth Business Day before the expected Closing Date of any scheduled commitments to dispatch the Project on or following the expected Closing Date and any known potential limitations, restrictions or outages affecting the Project for the two weeks following such notification. Seller shall promptly update such information and inform Buyer to the extent Seller becomes aware of any material changes to such information prior to the Closing. To the extent the Project has not been committed to dispatch on the expected Closing Date, then, by not later than 12 noon on the day before the expected Closing Date, Buyer shall provide Seller its preliminary hourly schedule for energy for dispatch the following day at the Project (which schedule shall include designation of quantity and time), and Seller shall cause the Project to be dispatched on the Closing Date in accordance with this day-ahead schedule.

(b) The Closing shall take place at the offices of Shearman & Sterling LLP at 10:00 A.M. local time, on the fifth Business Day after the conditions to Closing set forth in Articles VII and VIII (other than actions to be taken or items to be delivered at Closing) have been satisfied (or waived by the Party entitled to waive such condition), or on such other date and at such other time and place as Buyer and Seller mutually agree in writing. All actions listed in Section 7.9 or 8.6 that occur on the Closing Date shall be deemed to occur simultaneously at the Closing. The Closing shall be deemed effective as of 12:01 A.M. (Eastern time) on the Closing Date.

Section 2.4 Net Working Capital Adjustment.

(a) At least 10 Business Days prior to the expected Closing Date, Seller will deliver to Buyer a worksheet setting forth Seller’s good faith reasonable estimate of the expected Net Working Capital Adjustment Amount as of the expected Closing Date (the “Estimated Net Working Capital Adjustment Amount”), as well as a computation thereof. If the Estimated Net Working Capital Adjustment Amount is a positive number, the Base Purchase Price payable at Closing will be increased by an amount equal to such Estimated Net Working Capital Adjustment Amount. If the Estimated Net Working Capital Adjustment Amount is a negative number, the Base Purchase Price payable at Closing will be decreased by an amount equal to such Estimated Net Working Capital Adjustment Amount.

(b) Within 60 days after the Closing, Seller will prepare and deliver to Buyer (i) an unaudited consolidated balance sheet of Newington Energy (the “Closing Balance Sheet”), prepared in accordance with GAAP applied on a basis consistent with the past practices of Seller, together with all work papers relating thereto, and (ii) a statement (the “Closing Statement”) setting forth a computation of the actual Net Working Capital Adjustment Amount as of the Closing Date and all other amounts to be determined under Section 2.2 (collectively, the “Actual Net Working Capital Adjustment Amount”). If within 60 days following delivery of the Closing Balance Sheet and the Closing Statement Buyer does not object in writing thereto to Seller, then the Actual Net Working Capital Adjustment Amount shall be as reflected on the Closing Statement. If within such 60 days Buyer objects to Seller in writing to such computation, then Seller and Buyer shall negotiate in good faith and attempt to resolve their

disagreement. Should such negotiations not result in an agreement within 20 days after receipt by Seller of such written objection from Buyer, then the matter shall be submitted to the Independent Accounting Firm. All fees and expenses relating to the work, if any, to be performed by the Independent Accounting Firm will be borne equally by Buyer and Seller. The Independent Accounting Firm will deliver to Buyer and Seller a written determination of the Actual Net Working Capital Adjustment Amount (such determination to include a worksheet setting forth all material calculations used in arriving at such determination and to be based solely on information provided to the Independent Accounting Firm by Buyer and Seller or their Affiliates) within 30 days of the submission of the dispute to the Independent Accounting Firm, which determination will be final, binding and conclusive on the Parties (absent manifest error). If, following the determination of the Actual Net Working Capital Adjustment Amount (as agreed between the Parties or as determined by the Independent Accounting Firm), the Estimated Net Working Capital Adjustment Amount less the Actual Net Working Capital Adjustment Amount is a positive number, then Seller shall be obligated to pay Buyer a cash payment equal to such positive number. If the Estimated Net Working Capital Adjustment Amount less the Actual Net Working Capital Adjustment Amount is a negative number, then Buyer shall be obligated to pay Seller a cash payment equal to the absolute value of such negative number. Any such payment, together with interest thereon at the rate of five percent (5%) per annum from the Closing Date through the date of payment, will be due and payable within 15 days after the Actual Net Working Capital Adjustment Amount is finally determined as provided in this Section 2.4(b) and will be payable by wire transfer of immediately available funds to such account or accounts as shall be specified by Buyer or Seller, as applicable.

(c) Following the Closing, Seller and Buyer shall cooperate and provide each other and, if applicable the Independent Accounting Firm, reasonable access to such books, records (including those of Newington Energy) and such employees of Seller or its Affiliates as are reasonably requested in connection with the matters addressed in Section 2.4 (b).

Section 2.5 Allocation of Purchase Price. Seller shall prepare and provide to Buyer within 60 days after the Closing, a schedule allocating the Purchase Price among the Purchased Assets (the “Purchase Price Allocation Schedule”). The Purchase Price Allocation Schedule shall be prepared in good faith and in accordance with applicable provisions of the Code. Buyer shall have reasonable opportunity to review and comment on the Purchase Price Allocation Schedule. Seller shall make such revisions to the Purchase Price Allocation Schedule as may be reasonably requested by Buyer and approved by Seller. After consideration of Buyer’s comments, Seller’s Purchase Price Allocation Schedule shall be binding on both Seller and Buyer for all federal income tax purposes; provided, that if upon the advice of tax counsel reasonably acceptable to Seller, Buyer believes that the Purchase Price Allocation Schedule (or any portion thereof) is materially incorrect, the Independent Accounting Firm shall determine whether the Purchase Price Allocation Schedule or such portion is materially incorrect and the determination of such Independent Accounting Firm shall be final. If the Independent Accounting Firm determines that the Purchase Price Allocation Schedule or such portion is not materially incorrect, Seller and Buyer shall be bound by the Purchase Price Allocation Schedule. If the Independent Accounting Firm determines that the Purchase Price Allocation Schedule (or

any portion thereof) is materially incorrect, Seller and Buyer shall be bound by the Purchase Price Allocation Schedule as adjusted by such Independent Accounting Firm. Neither Buyer nor Seller shall agree to any proposed adjustment to the Purchase Price Allocation Schedule by any taxing authority without first giving the other prior written notice and the opportunity to challenge such proposed adjustment. Seller and Buyer each shall prepare a mutually acceptable and substantially identical IRS Form 8594 “Asset Acquisition Statement Under Section 1060” consistent with the Purchase Price Allocation Schedule which the Parties shall use to report the transactions contemplated by this Agreement to the applicable taxing authorities. The Purchase Price Allocation Schedule shall be revised to take into account subsequent adjustments to the Purchase Price, including any indemnification payments (which shall be treated for Tax purposes as adjustments to the Purchase Price), in accordance with the provisions of Section 1060 of the Code and the Treasury Regulations thereunder.

(a) Within 10 days after the Closing Date, Buyer shall cause Newington Energy to change its name to a name that does not contain any of the Seller Marks.

(b) Within 30 days after the Closing Date, Buyer shall provide evidence that is reasonably acceptable to Seller, that Buyer has made all filings required pursuant to paragraph (a) above with, and has provided notice to, all applicable Governmental Authorities and all counterparties to the Material Contracts regarding the sale of Newington Energy and the Purchased Assets thereof to Buyer and the new addresses for notice purposes.

Section 6.5 Support Obligations. (a) Buyer recognizes that Seller and/or certain of the Non-Newington Affiliates have provided credit support to Newington Energy with respect to the Project pursuant to certain credit support obligations, all of which that are outstanding as of the date hereof are set forth on Schedule 6.5 (such support obligations contained in Schedule 6.5 are hereinafter referred to as the “Support Obligations”).

(b) Prior to Closing, Buyer shall use its commercially reasonable efforts to effect the full and unconditional release, effective as of the Closing Date, of the Seller and Non-Newington Affiliates from all Support Obligations, including by using commercially reasonable efforts to:

(i) furnish a letter of credit to replace each existing letter of credit that is a Support Obligation containing terms and conditions that are substantially similar to the terms and conditions of such existing letter of credit and from lending institutions that have a Credit Rating commensurate with or better than that of lending institutions for such existing letter of credit;

(ii) institute an escrow arrangement to replace each existing escrow arrangement that is a Support Obligation with terms equal to or more favorable to the counterparty thereunder than the terms of such existing escrow arrangement;

(iii) furnish a guaranty to replace each existing guaranty that is a Support Obligation, which replacement guaranty is issued by a Person having a net worth or Credit Rating acceptable to the beneficiary of such existing guaranty, and containing terms and conditions that are substantially similar to the terms and conditions of such existing guaranty;

(iv) post a surety or performance bond to replace each existing surety or performance bond that is a Support Obligation, which replacement surety or performance bond is issued by a Person having a net worth and Credit Rating at least equal to those of the issuer of such existing surety or performance bond, and containing terms and conditions that are substantially similar to the terms and conditions of such existing surety or performance bond; and

(v) replace any other security agreement or arrangement on substantially similar terms and conditions to the existing security agreement or arrangement that is a Support Obligation.

Nothing contained in this Agreement shall prohibit Buyer from furnishing a letter of credit to replace each of the Support Obligations described in Sections 6.5(b)(ii) though (v) above, in each case, containing terms and conditions that provide credit support substantially similar to the existing Support Obligations and such letters of credit shall be from lending institutions that have a Credit Rating acceptable to each obligee.

(c) Buyer and Seller shall cooperate and use their commercially reasonable efforts to cause the beneficiary or beneficiaries of such Support Obligations to (i) remit any cash to Seller or one of its Affiliates, as applicable, held under any escrow arrangement that is a Support Obligation promptly following the replacement of such escrow arrangement pursuant to Section 6.5(b)(ii) and (ii) terminate, surrender and redeliver to Seller, one of its Affiliates or Seller’s other designee each original copy (to the extent reasonably practicable) of each original guaranty, letter of credit or other instrument constituting or evidencing such Support Obligations.

(d) If Buyer is not successful, following the use of its commercially reasonable efforts, in obtaining the complete and unconditional release of Seller and the Non-Newington Affiliates from any Support Obligations by the Closing Date (each such Support Obligation, until such time as such Support Obligation is released in accordance with Section 6.5(d)(i), a “Continuing Support Obligation”), then:

(i) from and after the Closing Date, Buyer shall continue to use its commercially reasonable efforts to obtain promptly the full and unconditional release of Seller and the Non-Newington Affiliates from each Continuing Support Obligation;

(ii) from and after Closing, Buyer shall reimburse and indemnify Seller and the Non-Newington Affiliates for, from and against any liabilities, losses, costs or expenses incurred by Seller or the Non-Newington Affiliates in connection with any

and all Continuing Support Obligations (including any demand or draw upon, or withdrawal from, or payment under any Continuing Support Obligation, the amount of which shall be reimbursed by Buyer within 3 Business Days of demand therefor to Buyer of the demand or request for payment under the Continuing Support Obligation), except to the extent that any such liabilities, losses, costs or expenses are incurred as a result of the failure by Seller or any Non-Newington Affiliate to comply with the terms of any Continuing Support Obligation; and

(iii) as security for Buyer’s obligations pursuant to Section 6.5(d)(ii) (which security may be drawn down upon if Buyer does not timely perform its obligations pursuant to Section 6.5(d)(ii)), Buyer shall deliver to Seller at the Closing and maintain at all times thereafter until the full and unconditional release of each Continuing Support Obligation in accordance with Section 6.5(d)(i) (the “Permitted Expiry”) a letter of credit (the “Buyer L/C”) that satisfies the Letter of Credit Requirements and is in the amount of the total of the maximum available amounts under all Continuing Support Obligations combined as such maximum available amounts for each Support Obligation are listed on Schedule 6.5(a), it being understood and agreed that subject to Section 6.3, Schedule 6.5(a) may be modified by one or more Updated Schedules during the Interim Period to reflect increased maximum available amounts under one or more Support Obligations above those shown for such Support Obligation on Schedule 6.5(a) as of the execution of this Agreement, which increased maximum amounts were reasonably required during the Interim Period in order for Newington Energy to operate in the ordinary course of business consistent with past practice, or to reflect the maximum amounts of Support Obligations that were not listed on Schedule 6.5(a) as of the execution of this Agreement but which were reasonably required during the Interim Period in order for Newington Energy to operate in the ordinary course of business consistent with past practice; provided, however, that the total of the incremental increases in the maximum available amounts under the Support Obligations listed on Schedule 6.5(a) as of the execution of this Agreement and the maximum amounts of the Support Obligations that were furnished anew during the Interim Period shall not exceed an amount equal to twenty percent (20%) of the total of the maximum available amounts under the Support Obligations as listed on Schedule 6.5(a) as of the execution of this Agreement; and provided further that to the extent the aggregate amount of the Continuing Support Obligations is reduced on or after the Closing Date pursuant to Section 6.5(d)(i), Buyer shall be entitled to amend or reduce the available amount under or replace the Buyer L/C from time to time to reflect such reduction. If at any time prior to the Permitted Expiry, the Buyer L/C has an expiration date earlier than the Permitted Expiry, then the Buyer shall cause to be provided to Seller, at least thirty (30) days prior to the expiration date of the Buyer L/C, a substitute Buyer L/C (which may consist of an amendment to the Buyer L/C) containing an expiration date that is at least ninety (90) days later than the expiration date of the Buyer L/C it is amending or replacing. If, at any time prior to the Permitted Expiry, the Credit Rating of the bank issuing the Buyer L/C falls below the level specified in the Letter of Credit Requirements or such bank

repudiates its obligation under, or fails to honor or pay against, the Buyer L/C, the Buyer shall cause to be furnished to Seller a substitute Buyer L/C promptly (and, in any event, within three (3) Business Days) after written notice demanding such substitute Buyer L/C has been given to Buyer. In each case where a substitute Buyer L/C is required to be furnished pursuant to this Agreement, the substitute Buyer L/C shall be required to comply with all requirements pertaining to the Buyer L/C set forth in this Agreement, including the Letter of Credit Requirements, and shall be considered the Buyer L/C following its provision. Concurrently with Seller’s receipt of a substitute Buyer L/C, Seller shall return to Buyer any Buyer L/C that is being replaced by such substitute Buyer L/C. Should Buyer fail to cause a substitute Buyer L/C to be furnished within the time specified in, and as otherwise required by, this Agreement, including under circumstances where (a) the Credit Rating of the bank issuing the Buyer L/C falls below the level specified in the Letter of Credit Requirements, (b) the bank issuing the Buyer L/C repudiates its obligations under, or fails to honor or pay against, the Buyer L/C, or (c) the expiration date of the Buyer L/C is required to be extended, then the aggregate amount then outstanding of the Continuing Support Obligations shall be owed to Seller for use as a cash security deposit and Seller may, without limitation or duplication of any other rights or remedies that may be available to it, draw down the entire remaining amount of the Buyer L/C in the same manner as provided in the next sentence. Should Seller exercise its rights under this Section 6.5(d)(iii) to draw down the entire remaining amount of the Buyer L/C, the cash obtained as a result of such drawing shall be utilized as a cash security deposit for the performance by Buyer of its obligations in Section 6.5(d)(ii), with the right to draw upon such cash security deposit in accordance with the terms hereof at any time prior to the Permitted Expiry to the same extent that the Buyer L/C could have been drawn upon had it remained in force and effect (and assuming that the expiration date of the Buyer L/C was the Permitted Expiry). If, for any reason, cash is not furnished to Seller within the time for payments under the Buyer L/C and in the amount of, and otherwise in accordance with, the drawing request under the Buyer L/C as contemplated above, then the Buyer shall remain obligated to furnish a substitute Buyer L/C within the applicable time set forth in this Agreement for furnishing a substitute Buyer L/C. Assuming that cash in the amount of, and otherwise in accordance with, the drawing request under the Buyer L/C is furnished to Seller within the time for payments under the Buyer L/C, then Buyer may at any time thereafter furnish a substitute Buyer L/C to Seller and, if the required substitute Buyer L/C is so furnished to Seller (and, in any event, promptly after the Buyer L/C Permitted Expiry), Seller shall return to Buyer a sum of cash equal to (a) the amount of the cash security deposit obtained as a result of the draw down upon the prior Buyer L/C as permitted by this Section 6.5(d)(iii), minus (b) the aggregate amount of any and all drawings made by Seller on such cash security deposit as permitted hereunder. Seller shall be required to keep any cash security deposit in a separate interest bearing account, and, shall not be entitled to use, possess, invest, commingle, assign, sell, or pledge such cash security deposit for any purpose other than drawing upon such cash security deposit in accordance with the terms hereof. Any interest on such cash security deposit shall be the sole property of Buyer;

(e) Seller and the Non-Newington Affiliates may not terminate any Continuing Support Obligations at any time on or after the Closing Date.

(f) During the Interim Period, Buyer shall have the right to contact and have discussions with each beneficiary of a Support Obligation in order to satisfy its obligations under this Section 6.5; provided that (i) Buyer shall give Seller prior notice before making any such contact, (ii) Seller have the right to have one of its Representatives present via telephone or in person, as applicable, during any such contact or discussion, (iii) Buyer shall contact and hold discussions with such beneficiaries only through Representatives of Buyer previously approved by Seller and (iv) Buyer shall cause such Representatives to comply with all procedures and protocols regarding such contacts and discussions that may be established by Seller.

Section 6.6 Termination of Certain Services and Contracts.

(a) Subject to Section 6.6(b), prior to the Closing, Seller shall (without further liability of Newington Energy thereunder or therefor) (i) terminate, sever, or assign to Seller or a Non-Newington Affiliate effective upon or before the Closing any services provided to Newington Energy by Seller or a Non-Newington Affiliate, including the termination or severance of insurance policies (including those policies referred to in Section 6.8), Tax services, legal services and banking services (to include the severance of any centralized clearance accounts) and (ii) use commercially reasonable efforts to terminate or assign to Seller or a Non-Newington Affiliate each Contract listed on Schedule 6.6 (such Contracts listed, collectively, the “Terminated Contracts”).

(b) Seller agrees that promptly following the date hereof Seller and Buyer shall organize a transition team to coordinate the transition activities during the Interim period, for the purposes of developing a plan for the transition of the Project from Seller to Buyer. Seller shall cooperate in good faith to provide such support and resources as may be reasonably required to implement such transition. Seller shall use commercially reasonable efforts to facilitate discussions between the Buyer and the counterparties to Material Contracts in connection with the implementation of the transition plan. Each of the Seller, Buyer and their respective Affiliates will bear the costs each incurs in planning and implementing the transition plan; provided, however, that Seller shall not be required to incur any additional third-party out-of-pocket costs in connection with the services provided by Seller or its affiliates or any third-party pursuant to this Section 6.6(b).

Section 6.7 Distributions. Notwithstanding anything in this Agreement to the contrary, Seller shall have the right to cause Newington Energy to pay cash dividends, make cash distributions to Seller or its Affiliates at any time prior to the Closing.

Section 6.8 Insurance. Buyer acknowledges and agrees that the insurance policies described on Schedule 4.15 shall not be transferred to Buyer, Newington Energy, or Buyer’s Affiliates or be retained or assumed by Newington Energy on or after the Closing. Seller shall maintain or cause to be maintained in full force and effect the insurance policies described on

Schedule 4.15 (as such Schedule may be modified by an Updated Schedule) throughout the Interim Period. Any and all such insurance coverage available under such insurance policies with respect to or relating to Newington Energy, its Assets, operations or properties, may, in Seller’s sole discretion, be cancelled or terminated for the period beginning on the Closing; provided that following the Closing, Seller shall be responsible for all claims and claim recovery, to the extent arising from events that occurred prior to the Closing and which are covered (or would have been covered, but for the termination of any policy) by the terms and conditions of the insurance policies listed under the heading “Section 6.9 Insurance Policies” on Schedule 4.15 (collectively, the “Applicable Insurance Policies” and each, an “Applicable Insurance Policy”) and shall submit such claims for coverage under the Applicable Insurance Policies or shall be liable for such coverage amount in the event that the Applicable Insurance Policy has been terminated by Seller. Seller agrees to be responsible for the applicable deductible associated with such claim under the Applicable Insurance Policy, but Seller shall not be responsible for any portion of any claim to the extent such portion is denied by the insurance carrier nor shall Seller be responsible for any portion of any claim to the extent such portion is not covered because of one or more exclusions, coverage limits or sublimits, or other terms and conditions of any Applicable Insurance Policy other than the deductible associated with such claim. Other than as expressly set forth in this Section 6.8, Seller shall have no responsibility, from and after the Closing, with respect to insurance for any of the Newington Energy, its Assets, operations, properties, officers, directors or employees for any periods from and after the Closing.

Section 6.9 Casualty.

(a) If any of the Purchased Assets is damaged or destroyed during the Interim Period, then:

(i) as promptly as practicable after such damage or destruction occurs, the aggregate cost of restoring such damaged or destroyed Purchased Assets to their condition immediately prior to such damage or destruction (the “Restored Condition”) shall, subject to Section 6.9(d), be determined by a qualified engineering firm reasonably acceptable to Buyer and Seller (the “Qualified Engineering Firm”) (such aggregate cost with respect to all such Purchased Assets, the “Full Restoration Cost”);

(ii) Seller shall (unless the Buyer shall have elected its termination right set forth in Section 6.9(b)), as promptly as practicable after such damage or destruction occurs and through the end of the Interim Period, undertake at its sole cost and expense to replace, repair, rebuild or restore such Purchased Assets to the Restored Condition, it being understood that the obligation of Seller to proceed with such replacement, repair, rebuilding or restoration may, after consultation with and agreement from the Buyer, continue beyond the Closing if Seller elects (the “Repair Election”) to continue with such replacement, repair, rebuilding or restoration after Closing, in which event, Seller shall repair, rebuild or restore such Purchased Assets to the Restored Condition (i) at its sole cost and expense, (ii) in accordance with good utility practices and Permits applicable to it, Buyer or Newington Energy, and in accordance, in all

material respects, with all Laws, (iii) as promptly as reasonably practicable (taking into account good utility practices), and (iv) in consultation with Buyer or Newington Energy;

(iii) unless the Seller shall have made the Repair Election, the Purchase Price shall be reduced by an amount equal to the remaining aggregate cost, as of Closing, to complete the replacement, repair, rebuilding or restoration of such damaged or destroyed Purchased Assets to the Restored Condition, as estimated by the Qualified Engineering Firm (the “Closing Restoration Cost”), which Closing Restoration Cost shall be reduced by the amount of any related insurance proceeds paid to and, after the Closing, retained by Newington Energy (the “Casualty Insurance Proceeds”); provided that if the Parties are unable to obtain an estimate of the Closing Restoration Cost from the Qualified Engineering Firm prior to the Closing Date, then the Parties shall reasonably agree in good faith with respect to such Closing Restoration Cost and, within 10 Business Days of the determination by the Qualified Engineering Firm following Closing of the Closing Restoration Cost, the Parties shall reimburse each other for any overpayment or underpayment, as applicable, as of Closing of the Closing Restoration Cost, based on the Qualified Engineering Firm’s determination thereof;

(iv) such casualty loss shall not otherwise affect the Closing;

(v) if any such damaged or destroyed Purchased Assets have not been restored to the Restored Condition prior to Closing, then, for up to eight full weeks immediately following the Closing, Seller shall pay to Buyer an amount equal to the greater of (A) the Weekly BI Proceeds for such week, or (B) a weekly amount equal to (I) $500,000, if the Project is unable to produce electricity because of such damage or destruction or (II) $250,000 if only one combustion turbine is able to produce electricity because of such damage or destruction; provided, that in all cases, amounts paid pursuant to this Section 6.9(a)(v) shall be pro-rated for partial weeks;

(vi) for purposes of clause (v) above, “Weekly BI Proceeds” means the amount of any business interruption insurance proceeds paid to and retained by Seller with respect to any period following the Closing and with respect to any Purchased Assets that have not been restored to the Restoration Condition prior to Closing; and

(vii) if Seller receives any Weekly BI Proceeds for any week following the eighth full week after the Closing, then Seller shall promptly remit such Weekly BI Proceeds to Buyer.

(b) If any of the Purchased Assets is damaged or destroyed during the Interim Period and the Full Restoration Cost is in excess of 10% of the Base Purchase Price, then Buyer may elect to terminate this Agreement by providing written notice to Seller.

(c) If, following the Closing, any Casualty Insurance Proceeds are paid to and retained by Newington Energy in connection with any damage or destruction to any

Purchased Assets during the Interim Period and if the Closing Restoration Cost has not been reduced by the amount of such Casualty Insurance Proceeds, then Buyer shall pay to Seller the amount of such Casualty Insurance Proceeds within 10 Business Days of the receipt thereof.

(d) If, in the Seller’s reasonable judgment (i) the cost of restoring such damaged or destroyed Purchased Assets to the Restored Condition is less than $5 million and (ii) such restoration will be completed by the expected Closing Date, the requirement to engage the Qualified Engineering Firm shall not apply.

Section 6.10 Condemnation. If any of the Purchased Assets is taken by condemnation during the Interim Period and such Purchased Assets have an aggregate condemnation value (as determined by a qualified firm reasonably acceptable to Buyer and Seller) (such aggregate value with respect to such Purchased Assets net of the reasonable costs of recovery, the “Condemnation Value”) greater than $5,000,000 but do not have a Condemnation Value in excess of 20% of the Base Purchase Price, then Seller may elect to reduce the Purchase Price by such Condemnation Value (less the amount of any condemnation award proceeds which shall be paid to Buyer) by notice to Buyer, and such condemnation shall not affect the Closing. If Seller does not make such an election within 45 days after the award of the condemnation proceeds (or, if earlier, at least 10 Business Days prior to the expected Closing) or, if as a result of such condemnation the balance of the Purchased Assets, considered collectively, cannot be used in a reasonably efficient manner for its current purposes, Buyer may elect to terminate this Agreement by written notice to Seller. If the Condemnation Value is in excess of 20% of the Base Purchase Price, Buyer may, by notice to Seller within 45 days after the award of the condemnation proceeds (or, if earlier, at least 10 Business Days prior to the expected Closing), elect to (a) reduce the Purchase Price by such Condemnation Value (after giving effect to any condemnation award proceeds which shall be paid to Buyer along with any related Tax benefits available to Buyer) or (b) terminate this Agreement, in each case by providing written notice to Seller. If the Condemnation Value is $5,000,000 or less, (A) neither Buyer nor Seller shall have the right or option to terminate this Agreement and (B) the Purchase Price shall be reduced by an amount equal to the excess of the Condemnation Value over the amount of any condemnation award proceeds paid to Buyer. If the Parties are unable to obtain an estimate of the Condemnation Value from a qualified firm reasonably acceptable to the Parties prior to the Closing Date, then the Parties shall reasonably agree in good faith with respect to such Condemnation Value, and the Purchase Price shall be reduced accordingly pursuant to the terms of this Section 6.10. Within 10 Business Days of the determination by such firm following Closing of the Condemnation Value, the Parties shall reimburse each other for any overpayment or underpayment as of Closing of the Condemnation Value, based on such firm’s determination thereof.

Section 6.11 Transfer Taxes. Notwithstanding anything in this Agreement to the contrary Seller shall bear 50% and Buyer shall bear 50% of the total of all Transfer Taxes attributable to the transfer of the Membership Interests including the Project Purchase and the Sale of the Membership Interests, and if either Seller or Buyer is required by Law to pay more than its half of any such Transfer Taxes, the other shall promptly reimburse Seller or Buyer, as

applicable, for amounts in excess of such half. Seller and Buyer shall timely file their own Transfer Tax returns as required by Law and shall notify the other Party when such filings have been made. Seller and Buyer shall each use all commercially reasonable efforts to reduce the amount of Transfer taxes payable in connection with the transactions contemplated herein, including the sale of the Purchased Interests, and cooperate and consult with each other prior to filing such Transfer Tax returns to ensure that all such returns are filed in a consistent manner. Without limiting the foregoing, Buyer shall be solely responsible for any Transfer Taxes arising from any action to dissolve, terminate or restructure Newington Energy or to convey, distribute or transfer any assets, properties or other rights by deed, ▇▇▇▇ of sale or otherwise to or from Newington Energy on or after the Closing Date.

Section 6.12 Tax Matters. Except as provided in Section 6.11 relating to Transfer Taxes:

(a) With respect to any Tax return covering a taxable period ending on or before the Closing Date (a “Pre-Closing Taxable Period”) that is required to be filed after the Closing Date with respect to Newington Energy (i) Seller shall cause such Tax return to be prepared and shall deliver such Tax return as so prepared, to Buyer not later than 30 days prior to the due date for filing such Tax return, (ii) Buyer and Seller shall cooperate and consult with each other in order to finalize such Tax return, and (iii) Buyer shall thereafter cause such Tax return to be executed and duly and timely filed with the appropriate taxing authority and shall pay all Taxes due with respect to the period covered by such Tax return. With respect to any Tax return covering a taxable period beginning on or before the Closing Date and ending after the Closing Date (a “Straddle Taxable Period”) that is required to be filed after the Closing Date with respect to Newington Energy (x) Buyer shall cause such Tax return to be prepared (in a manner consistent with practices followed in prior taxable periods except as required by a change in Law or fact) and shall deliver a draft of such Tax return to Seller for Seller’s review and approval at least 30 days prior to the due date for filing such Tax return, (y) Seller and Buyer shall cooperate and consult with each other in order to finalize such Tax return, and (z) thereafter Buyer shall cause such Tax return to be executed and duly and timely filed with the appropriate taxing authority and shall pay all Taxes due with respect to the period covered by such Tax return.

(b) As between Seller and Buyer, Seller shall be responsible for and indemnify Buyer against, and Seller shall be entitled to all refunds or credits of (except as resulting from the carry back of a Tax attribute relating to a taxable period after the Closing Date), (i) any Tax with respect to Newington Energy that is attributable to a Pre-Closing Taxable Period or to that portion of a Straddle Taxable Period that ends on the Closing Date (other than Taxes attributable to Buyer having not timely filed any Tax Return in accordance with this Section 6.12), and (ii) any Taxes imposed on Newington Energy under United States Treasure Regulation Section 1.1502-6 (or any similar provision of state, local or foreign Law), in each case to the extent that such Tax exceeds the amount (if any) reflected as a current liability for such Tax in the Net Working Capital. Within five days prior to the due date for the payment of any such Tax, if (i) the amount of such Tax for which Seller is responsible exceeds (ii) the

amount reflected as a current liability for such Tax in the Net Working Capital, Seller shall pay to Buyer an amount equal to such excess, and if the amount described in clause (ii) exceeds the amount described in clause (i), Buyer shall pay to Seller the amount of such excess. With respect to a Straddle Taxable Period, Seller shall determine the Tax attributable to the portion of the Straddle Taxable Period that ends on the Closing Date by an interim closing of the books of Newington Energy as of the Closing Date, except for ad valorem or property Taxes (“Property Taxes”) and franchise Taxes based solely on capital (and other Taxes imposed on a periodic basis with respect to one or more assets or otherwise measured by the level of any item) which shall be prorated on a daily basis to the Closing Date. For this purpose, any franchise Tax paid or payable with respect to Newington Energy shall be allocated to the taxable period for which payment of the Tax provides the right to engage in business, regardless of the taxable period during which the income, operations, assets or capital comprising the base of such Tax is measured. In determining whether a Property Tax is attributable to a Pre-Closing Taxable Period or a Straddle Taxable Period, any Property Tax that is based on the assessed value of any assets, property or other rights as of any lien date or other specified valuation date shall be deemed a Property Tax attributable to the taxable period (whether a fiscal year or other tax year) specified on the relevant Property Tax ▇▇▇▇ that is issued with respect to that lien date or other valuation date.

(c) Buyer shall be responsible for and indemnify Seller against all Taxes of Newington Energy that are not the responsibility of Seller, and Buyer shall be entitled to all refunds and credits of all Taxes of Newington Energy to which Seller is not entitled, pursuant to Section 6.12(b).

(d) With respect to any Tax for which Seller is responsible pursuant to Sections 6.12(a) and (b), Seller shall have the right, at its sole cost and expense, to initiate any claim for refund and to control the prosecution, settlement or compromise of any proceeding involving such Tax, including the determination of the value of property for purposes of real and personal property ad valorem Taxes. Buyer shall (and shall cause Newington Energy to) take such action (at Seller’s sole cost and expense) in connection with any such proceeding as Seller shall reasonably request from time to time to implement the preceding sentence, including the selection of counsel and experts and the execution of powers of attorney. Buyer shall (and shall cause Newington Energy to) give written notice to Seller of its receipt of any notice of any audit, examination, claim or assessment for any Tax for which Seller may be responsible within 20 days after its receipt of such notice; failure to give any such written notice within such 20-day period shall cause Buyer to forfeit any rights it may have by reason of Section 4.9 or this Section 6.12 but only to the extent Seller is actually prejudiced by such failure.

(e) Seller shall grant to Buyer (or its designees) access at all reasonable times to all of the information, books and records relating to Newington Energy within the possession of Seller (including workpapers and correspondence with taxing authorities), and shall afford Buyer (or its designees) the right (at Buyer’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit Buyer (or its designees) to prepare Tax returns, respond to Tax audits and investigations, prosecute Tax protests, appeals and refund

claims and to conduct negotiations with taxing authorities. Buyer shall grant or cause Newington Energy to grant to Seller (or its designees) access at all reasonable times to all of the information, books and records relating to Newington Energy within the possession of Buyer (including workpapers and correspondence with taxing authorities) and to the employees of General Electric International, Inc. and any other entity responsible for operation and management of the Project, and shall afford Seller (or its designees) the right (at Seller’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit Seller (or its designees) to prepare Tax returns, respond to Tax audits and investigations, prosecute Tax protests, appeals and refund claims and to conduct negotiations with taxing authorities. After the Closing Date, Seller and Buyer will preserve all information, records or documents in their respective possessions relating to liabilities for Taxes of Newington Energy until six months after the expiration of any applicable statute of limitations (including extensions thereof) with respect to the assessment of such Taxes; provided that neither Party shall dispose of any of the foregoing items without first offering such items to the other Party.

(f) If, after the Closing, Buyer or Newington Energy receives a refund or utilizes a credit of any Tax of Newington Energy attributable to a Pre-Closing Taxable Period or that portion of a Straddle Taxable Period ending on the Closing Date to the extent that such refunded or credited Tax was not reflected in the Net Working Capital, Buyer shall pay to Seller within 30 days after such receipt or utilization an amount equal to such refund received or credit utilized, together with any interest received or credited thereon. Buyer shall, and shall cause Newington Energy to, take such action to obtain a refund or credit of any Tax of Newington Energy attributable to a Pre-Closing Taxable Period or that portion of a Straddle Taxable Period ending on the Closing Date or to mitigate, reduce or eliminate any such Tax that could be imposed for a Pre-Closing Taxable Period or that portion of a Straddle Taxable Period ending on the Closing Date (including with respect to the transactions contemplated hereby) as is reasonably requested by Seller on a case-by-case basis.

(g) In the event that Seller initiates a claim for refund from a taxing authority with regard to any Tax of Newington Energy attributable to a Pre-Closing Taxable Period or that portion of a Straddle Taxable Period ending on the Closing Date, whether the initiation of such claim begins prior to or after the Closing, Seller shall have all rights to and interest in such refund. Buyer shall, upon request, provide Seller a limited power of attorney allowing Seller to pursue such claim for refund with and collect such refund from such taxing authority. If, after the Closing, Buyer or Newington Energy receives a refund or utilizes a credit of any such Tax with regard to a claim so initiated by Seller, Buyer shall pay to Seller within 30 days after such receipt or utilization an amount equal to such refund received or credit utilized, together with any interest received or credited thereon.

(h) In the event that Seller initiates a claim for refund from a third party who improperly withheld sales and use Tax, or withheld excessive sales and use Tax, with regard to Newington Energy attributable to a Pre-Closing Taxable Period or that portion of a Straddle Taxable Period ending on the Closing Date, whether the initiation of such claim begins prior to

or after the Closing, Seller shall have all rights to and interest in such refund to the extent that it was not reflected in the Net Working Capital. Buyer shall, upon request, provide Seller a limited power of attorney allowing Seller to pursue such claim for refund with and collect such refund from such third party. If after the Closing Buyer or Newington Energy receives a refund of any such Tax with regard to a claim so initiated by Seller, Buyer shall pay to Seller within 30 days after such receipt an amount equal to such refund received, together with any interest received or credited thereon.

Section 6.13 Affiliate Contracts. Effective upon Closing, Seller on behalf of itself and its Non-Newington Affiliates, hereby irrevocably and unconditionally releases and waives any Claim of any nature howsoever and whensoever arising against Newington Energy.

Section 6.14 Appointment of Representatives. In order to facilitate the consummation of the transactions contemplated by this Agreement, each Party shall designate a representative to act as the primary point of contact to coordinate communications and other interaction between the Parties during the Interim Period.

Section 6.15 Updating Schedules. Prior to Closing, Seller shall (in reasonable detail so that Buyer can understand the consequence thereof) in writing by notice to the Buyer supplement and/or otherwise amend the Material Contracts List and only those Schedules which relate to the matters contained in Articles III and IV hereof, including by the addition of new schedules with respect to any representations and warranties of Seller in this Agreement for which no schedule was provided as of the date hereof (such Schedules as supplemented and/or otherwise amended and any such new schedules, being collectively referred to herein as the “Updated Schedules,” and such Material Contracts List as supplemented and/or otherwise amended being referred to herein as the “Updated Material Contracts List”), in each case with respect to matters arising after the date of this Agreement which matters, if existing as of the date of this Agreement, would have been set forth in such Schedules or the Material Contracts List; provided that the foregoing shall not apply with respect to any Schedule or potion of the Material Contracts List that relates solely to the date of this Agreement. Notwithstanding the foregoing, no Updated Schedule or Updated Material Contracts List shall be deemed to have cured any breach of any representation or warranty made by Seller as of the date of this Agreement, unless Buyer otherwise consents in writing. Seller and Buyer acknowledge and agree that the inclusion of any item or statement in any Schedule, Material Contracts List, Updated Schedule or Updated Material Contracts List, which item or statement was not required to be included in such documents (because it does not meet a threshold amount for inclusion or for any other reason), shall not be construed to create any obligation to include any item or statement in the same or any different Schedule, Material Contracts List, Updated Schedule or Updated Material Contracts List, which item or statement is not required to be so included (because it does not meet a threshold amount for inclusion or for any other reason). Seller agrees to advise Buyer promptly in writing of any matter or occurrence of which it has or obtains Knowledge, and Buyer agrees to advise Seller promptly in writing of any matter of which Buyer has knowledge, which, in either case, may constitute a breach by either Party of any representation, warranty or covenant contained in this Agreement.

Section 6.16 Announcements. Prior to the Closing Date no press release or other public announcement, or public statement or comment in response to any inquiry, relating to this Agreement or the transactions contemplated hereby shall be issued or made by either Buyer or Seller, or any of their Affiliates, without the approval of Buyer or Seller, as the case may be; provided that a press release or other public announcement, regulatory filing, statement or comment made without such approval, including in furtherance of the requirements of Section 6.1, shall not be in violation of this Section 6.16 if it is made in order to comply with applicable Laws or stock exchange rules and in the reasonable judgment of the Party or its Affiliate making such release or announcement, based upon advice of counsel, prior review and joint approval, despite reasonable efforts to obtain the same, would prevent dissemination of such release or announcement in a fashion to comply with such Laws or rules; provided further that in all instances Buyer or Seller, as the case may be, shall provide prompt notice of any such release, announcement, statement or comment to the other Party.

Section 6.17 Liability of Seller and Newington Energy. Notwithstanding any other provision herein, the terms and provisions of this Section 6.17 apply in the event that (a) Seller has not materially breached any of its obligations under this Agreement and (b) Newington Energy has the right to purchase the Project pursuant to Section 13 of the Lease. If the circumstances described in the immediately-preceding sentence have occurred, but Hawkeye fails to convey the Project to Newington Energy pursuant to Sections 13 and 29(i) of the Lease, then (i) Seller shall, or shall cause Newington Energy to, diligently pursue all remedies and enforcement rights (including specific performance) that Newington Energy may have against Hawkeye to compel Hawkeye to so convey the Project to Newington Energy in accordance with the Lease, and (ii) Buyer agrees that, so long as Seller is in compliance with its obligation in the preceding clause (i), Buyer’s sole and exclusive remedy with respect to Seller and Newington Energy shall be as set forth in Section 9.1(c)(ii) and that it shall not bring any Claim, in contract, in tort or under any other legal theory, in law or in equity, against Seller, Newington Energy or any of their respective Affiliates or Representatives.

Section 6.18 Replacement Software Licenses. Prior to Closing, Buyer shall obtain or cause to be obtained, at no expense to Seller or any Non-Newington Affiliate, licenses and/or other agreements (collectively, the “Buyer’s Replacement Software Licenses”) that are separate agreements from Seller’s Software Licenses and that are sufficient to (i) lawfully permit Newington Energy, on and after the Closing Date, to continue to make use of the Seller’s Licensed Software in at least the manner and extent permitted under Seller’s Software Licenses, and (ii) lawfully permit Seller or the Non-Newington Affiliate that is the party to each Seller’s Software License to leave, on and after the Closing Date, the Sellers’ Licensed Software on the computer hardware, firmware or other equipment or devices on which it is stored, loaded, located or used prior to the Closing Date rather than removing the Seller’s Licensed Software therefrom; provided, that to the extent Buyer notifies Seller in writing at least 30 days prior the Closing Date that it will not make use of any particular Seller’s Licensed Software (collectively, the “Unnecessary Software”), then the Buyer’s Replacement Software Licenses that Buyer must otherwise obtain or cause to be obtained pursuant to this Section 6.18 need not include rights to make use of the Unnecessary Software set forth in Buyer’s written notice and Seller, on or prior

to the Closing Date, may cause the Unnecessary Software to be removed from the computer hardware, firmware or other equipment or devices on which it is stored, loaded, located or used.

Section 6.19 Certain Payments, Costs and Expenses. Except as provided in Section 6.12 relating to Tax Matters:

(a) In the event that, after the Closing Date, Seller or the Non-Newington Affiliates receive any payments relating to any period after the Closing from any Governmental Authority or any third parties with respect to the Project, Seller shall promptly remit such payments to the Buyer (or its designees).

(b) In the event that, after the Closing Date, Buyer or Newington Energy receive any bills or invoices from any Governmental Authority or any third parties for services provided to the Project during any period prior to the Closing, then, to the extent the amounts due pursuant to such bills or invoices are not reflected in the Actual Net Working Capital Adjustment Amount, Buyer shall remit payment to such Governmental Authority or third parties, as applicable, and Seller shall reimburse Buyer (or its designees) for the full amount thereof promptly upon determination of the Aggregate Net Working Capital Adjustment Amount.

Section 6.20 Certain Agreements Regarding the Project. During the Interim Period, with respect to the full unforced capacity for the Project, the parties shall (and Seller shall cause Newington Energy to) cooperate and consult with each other to ensure that Newington Energy has qualified the Project for the ISO New England, Inc., capacity market beyond May 2010.

Section 6.21 Further Assurances. Subject to the terms and conditions of this Agreement, at any time and from time to time after the Closing, at either Party’s request and without further consideration, the other Party shall execute and deliver to such requesting Party such other instruments of sale, transfer, conveyance, assignment and confirmation, provide such materials and information and take such other actions as such Party may reasonably request in order to consummate the transactions contemplated by this Agreement.

TERMINATION

Section 9.1 Termination. This Agreement may be terminated, and the transactions contemplated hereby, including the transfer of the Membership Interests, may be abandoned, as follows:

(a) at any time before the Closing, by Seller or Buyer, by written notice to the other, in the event that any Law or final, non-appealable court decision restrains, enjoins or otherwise prohibits or makes illegal the sale of the Membership Interests pursuant to this Agreement; provided that such final, non-appealable court decision has not resulted from any litigation or proceeding filed by the Party asserting a termination right under this Section 9.1(a) or its Affiliates;

(b) any time before the Closing, by Seller or Buyer (if the terminating Party is not in material breach of its obligations under this Agreement), by notice to the other, if the other has materially breached its obligations hereunder (including any representation, warranty, covenant or agreement) so as to cause the failure of a condition set forth in Article VII or Article VIII, as applicable, and such breach (other than a breach of Buyer’s obligation to pay the Purchase Price in accordance with the terms of Article II, for which no cure period shall be

allowed) has not been cured within the earlier of the Long Stop Date or 30 days following written notification thereof; provided that if, at the end of such 30 day period, and provided that such 30 day period shall have ended prior to the Long Stop Date, the breaching Party is endeavoring in good faith, and proceeding diligently, to cure such breach, the breaching Party shall have an additional period expiring on the earlier of 30 days thereafter and the Long Stop Date in which to effect such cure;

(c) by Buyer, by notice to Seller, (i) in the event Newington Energy no longer has the right to purchase the Project in accordance with Section 13 of the Lease or (ii) in the event that the Project Purchase does not occur by the Long Stop Date;

(d) by Seller, by notice to Buyer, in the event that the Project Purchase does not occur by the Long Stop Date; provided that Seller shall have no right to terminate this Agreement pursuant to this Section 9.1(d) if (i) Seller is in material breach of Section 2.1(a) or 6.17(a), or (ii) Newington Energy no longer has the right to purchase the Project in accordance with Section 13 of the Lease;

(e) at any time before the Closing, by Buyer or Seller, by notice to the other, on or after December 31, 2008 (the “Long Stop Date”); provided that if the failure to achieve Closing by the Long Stop Date is the result of a Party’s delay, such Party may not terminate this Agreement pursuant to this Section 9.1(e);

(f) by Buyer pursuant and subject to Sections 6.9 or 6.10; or

(g) by mutual written consent of Buyer and Seller.

Section 9.2 Effect of Termination. If this Agreement is validly terminated pursuant to Section 9.1, there will be no liability or obligation on the part of Seller or Buyer (or any of their respective Representatives or Affiliates), provided that (a) Sections 6.2(c), 6.16 and 9.3 and Article XI will survive any such termination and (b) subject to Sections 9.3 and 11.9, each Party shall continue to be liable for any breach of this Agreement by it occurring prior to such termination.

Section 9.3 Break-up Damages. (a) If this Agreement is terminated by Seller pursuant to Section 9.1(b) and if the basis for such termination is that Buyer has breached its obligations under Section 6.1(a) or 6.1(c) or its obligation to consummate the Closing in accordance with Section 2.3(b) (including by failure to pay the Purchase Price or perform its obligations under Section 8.6), then, in lieu of all other Claims and remedies that might otherwise be available to Seller with respect to such breaches and such termination and as Seller’s exclusive remedy therefor notwithstanding any other provision of this Agreement, Buyer shall pay Seller, by wire transfer of immediately available funds within 3 Business Days following the date of termination, as liquidated damages, an amount equal to 10% (ten percent) of the Base Purchase Price. If Buyer pays such amount in full by the time required, then Seller shall simultaneously return the Break-up L/Cs and/or substitute Break-up L/Cs, as applicable, to

Buyer. If Buyer does not pay such amount in full by the time required, then Seller may draw down the entire amount of the Break-up L/Cs and/or substitute Break-up L/Cs, as applicable.

(b) On the date hereof, Buyer will cause to be delivered to Seller letters of credit satisfying the Letter of Credit Requirements, in an aggregate amount sufficient to secure the Buyer’s obligation under Section 9.3(a) (each, a “Break-up L/C” and collectively, the “Break-up LCs”). If at any time prior to January 31, 2009 (the “Break-up Damages Stop Date”) (unless the Closing shall have occurred), a Break-up L/C has an expiration date earlier than the Break-up Damages Stop Date, then the Buyer shall cause to be provided to Seller, at least thirty (30) days prior to the expiration date of such Break-up L/C, a substitute Break-up L/C (which may consist of an amendment to a Break-up L/C) containing an expiration date that is at least thirty (30) days later than the expiration date of the Break-up L/C it is amending or replacing. If, at any time prior to the Break-up Damages Stop Date (unless the Closing shall have occurred), the Credit Rating of the bank issuing a Break-up L/C falls below the level specified in the Letter of Credit Requirements or such bank repudiates its obligations under, or fails to honor or pay against, a Break-up L/C, the Buyer shall cause to be furnished to Seller a substitute Break-up L/C promptly (and, in any event, within three (3) Business Days) after written notice demanding such substitute Break-up L/C has been given to Buyer. In each case where a substitute Break-up L/C is required to be furnished pursuant to this Agreement, the substitute Break-up L/C shall be required to comply with all requirements pertaining to Break-up L/Cs set forth in this Agreement, including the Letter of Credit Requirements, and shall be considered a Break-up L/C following its provision. Concurrently with Seller’s receipt of a substitute Break-up L/C, Seller shall return to Buyer any Break-up L/C that is being replaced by such substitute Break-up L/C. At the Closing, Seller shall deliver to Buyer all original Break-up L/Cs for cancellation as provided in Section 7.9(c). Should Buyer fail to cause a substitute Break-up L/C to be furnished within the time specified in, and as otherwise required by, this Agreement, including under circumstances where (a) the Credit Rating of the bank issuing a Break-up L/C falls below the level specified in the Letter of Credit Requirements, (b) the bank issuing the Break-up L/C repudiates its obligations under, or fails to honor or pay against, the Break-up L/C. or (c) the expiration date of a Break-up L/C is required to be extended, then the aggregate amounts specified therein shall be owed to Seller for use as a cash security deposit and Seller may, without limitation or duplication of any other rights or remedies that may be available to it, draw down such entire remaining amount in the same manner as provided in the next sentence. Should Seller exercise its rights under this Section 9.3(b) to draw down the entire amount of a Break-up L/C, the cash obtained as a result of such drawing shall be utilized as a cash security deposit for the performance by Buyer of its obligations under Section 9.3(a), with the right to draw upon such cash security deposit in accordance with the terms hereof at any time prior to the Break-up Damages Stop Date to the same extent that a Break-up L/C could have been drawn upon had it remained in force and effect (and assuming that the expiration date of such Break-up L/C was the Break-up Damages Stop Date). If, for any reason, cash is not furnished to Seller within the time for payments under a Break-up L/C and in the amount of, and otherwise in accordance with, the drawing request under such Break-up L/C as contemplated above, then the Buyer shall remain obligated to furnish a substitute Break-up L/C within the applicable time set

forth in this Agreement for furnishing a substitute Break-up L/C. Assuming that cash in the amount of, and otherwise in accordance with, the drawing request under a Break-up L/C is furnished to Seller within the time for payments under such Break-up L/C, then Buyer may at any time thereafter furnish a substitute Break-up L/C to Seller and, if such substitute Break-up L/C is so furnished to Seller, Seller shall return to Buyer a sum of cash equal to (a) the amount of the cash security deposit obtained as a result of the draw down upon the prior Break-up L/C as permitted by this Section 9.3(b), minus (b) the aggregate amount of any and all drawings made by Seller on such cash security deposit as permitted hereunder. Seller shall be required to keep any cash security deposit in a separate interest bearing account, and, shall not be entitled to use, possess, invest, commingle, assign, sell, or pledge such cash security deposit for any purpose other than drawing upon such cash security deposit in accordance with the terms hereof. Any interest on such cash security deposit shall be the sole property of Buyer

(c) If this Agreement is terminated by Buyer pursuant to Section 9.1(b) or 9.1(c)(i), then, in lieu of all other Claims and remedies against Seller or Newington Energy that might otherwise be available to Buyer with respect thereto, Seller shall pay Buyer, by wire transfer of immediately available funds within three Business Days following the date of termination, as liquidated damages, the sum of (i) all costs, fees and expenses or other liabilities incurred in connection with the Commitments and Alternative Financing or the definitive documents arising therefrom, as applicable, including all breakage, lenders’ legal fees, escrow and pre-payment fees, (ii) all interest or commitment fees paid or incurred by Buyer or its Affiliates in connection with the Commitment or Alternative Financing or the definitive documents arising therefrom that relate to the portion of such facilities intended to finance a portion of the Purchase Price hereunder, (iii) all costs, fees and expenses or other liabilities incurred in connection with any hedging or tolling arrangements entered into by Buyer or one of its affiliates that relate to Newington Energy and (iv) an amount equal to Buyer’s other actual and reasonable out-of-pocket fees (including reasonable attorney’s fees and regulatory filing fees) and expenses incurred in connection with this Agreement, subject, in the case of this Section 9.3(c), to an aggregate maximum of $40,000,000.

(c) The provision for payments of liquidated damages in this Section 9.3 has been included because, in the event of a breach by Seller or Buyer, the actual damages to be incurred by Seller or Buyer, as applicable, can reasonably be expected to approximate the amount of liquidated damages provided for herein and because the actual amount of such damages would be difficult if not impossible to measure accurately.

(b) NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, NO PARTY SHALL BE LIABLE FOR SPECIAL, PUNITIVE, EXEMPLARY, CONSEQUENTIAL OR INDIRECT DAMAGES OR LOST PROFITS, WHETHER BASED ON CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE AND WHETHER OR NOT ARISING FROM THE OTHER PARTY’S SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT (“Non-reimbursable Damages”).

(c) Notwithstanding anything in this Agreement to the contrary, no Representative or Affiliate of Seller shall have any personal liability to Buyer or any other Person as a result of the breach of any representation, warranty, covenant, agreement or obligation of Seller in this Agreement and no Representative or Affiliate of Buyer shall have any personal liability to Seller or any other Person as a result of the breach of any representation, warranty, covenant, agreement or obligation of Buyer in this Agreement.

Section 10.7 Procedure with Respect to Third-Party Claims. (a) If any Party (or as to Buyer after Closing, Newington Energy) becomes subject to a pending or threatened Claim of a third party and such Party (the “Claiming Party”) believes it has a Claim against the other Party (the “Responding Party”) as a result, then the Claiming Party shall notify the Responding Party in writing of the basis for such Claim setting forth the nature of the Claim in reasonable detail. The failure of the Claiming Party to so notify the Responding Party shall not relieve the Responding Party of liability hereunder except to the extent that the defense of such Claim is prejudiced by the failure to give such notice.

(b) If any proceeding is brought by a third party against a Claiming Party and the Claiming Party gives notice to the Responding Party pursuant to this Section 10.7, the Responding Party shall be entitled to participate in such proceeding and, to the extent that it wishes, to assume the defense of such proceeding, if (i) the Responding Party provides written notice to the Claiming Party that the Responding Party intends to undertake such defense, (ii) the Responding Party conducts the defense of the third-party Claim actively and diligently with counsel reasonably satisfactory to the Claiming Party and (iii) if the Responding Party is a party to the proceeding, the Responding Party has not determined in good faith that joint representation would be inappropriate because of a conflict in interest. The Claiming Party shall, in its sole discretion, have the right to employ separate counsel (who may be selected by the Claiming Party in its sole discretion) in any such action and to participate in the defense thereof, and the fees and expenses of such counsel shall be paid by such Claiming Party. The Claiming Party shall fully cooperate with the Responding Party and its counsel in the defense or compromise of such Claim. If the Responding Party assumes the defense of a proceeding, no compromise or settlement of such Claims may be effected by the Responding Party without the Claiming Party’s consent unless (A) there is no finding or admission of any violation of Law or any violation of the rights of any Person and no effect on any other Claims that may be made against the Claiming Party and (B) the sole relief provided is monetary damages that are paid in full by the Responding Party.

(c) If (i) notice is given to the Responding Party of the commencement of any third-party legal proceeding and the Responding Party does not, within 30 days after the Claiming Party’s notice is given, give notice to the Claiming Party of its election to assume the defense of such legal proceeding, (ii) any of the conditions set forth in clauses (i) through (iii) of Section 10.7(b) above become unsatisfied or (iii) a Claiming Party determines in good faith that there is a reasonable probability that a legal proceeding may adversely affect it other than as a result of monetary damages for which it would be entitled to indemnification from the Responding Party under this Agreement, then the Claiming Party shall (upon notice to the Responding Party) have the right to undertake the defense, compromise or settlement of such Claim; provided that the Responding Party shall reimburse the Claiming Party for the costs of defending against such third-party Claim (including reasonable attorneys’ fees and expenses) and shall remain otherwise responsible for any liability with respect to amounts arising from or related to such third-party Claim, in both cases to the extent it is determined that such Responding Party is liable with respect to such third-party Claim under this Agreement. The

Responding Party may elect to participate in such legal proceedings, negotiations or defense at any time at its own expense.

Section 10.8 Access to Information. After the Closing Date, Seller and Buyer shall grant each other (or their respective designees), and Buyer shall cause Newington Energy to grant to Seller (or its designees), access at all reasonable times upon reasonable notice to all of the information, books and records relating to Newington Energy in its possession, and shall afford such party the right (at such party’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to implement the provisions of, or to investigate or defend any claims between the Parties arising under, this Agreement.

Section 11.4 Disclosure. Seller may, at its option, include in the Schedules, the Updated Schedules, the Material Contracts List and the Updated Material Contracts List, items that are not material in order to avoid any misunderstanding, and any such inclusion, or any references to dollar amounts, shall not be deemed to be an acknowledgment or representation that such items are material, to establish any standard of materiality or to define further the meaning of such terms for purposes of this Agreement.

Section 11.5 Waiver. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition.
