ARTICLE I.
BASIC TRANSACTIONS

1.1 Sale and Purchase of the Shares and Owner Notes. Upon the terms and subject to the conditions contained in this Agreement, on the Closing Date the Share Sellers, severally, will, and EME will and will cause each of the other Owner Note Sellers to, sell, assign, transfer, convey and deliver to the Purchaser, acting on its own behalf or as agent for one or more Purchaser Designees, and the Purchaser agrees (as principal for itself and as agent for any Purchaser Designees) that it will purchase from EME and the other Sellers:

(a) The Shares; and

(b) All promissory notes and other obligations, if any, representing money borrowed by, or an installment obligation of, an Acquired Company (i) in the case of the Separately Sold Projects, to EME or its parents or Subsidiaries (other than the Project-Specific Acquired Companies included in the Separately Sold Projects (the "Project Notes"), unless and to the extent that the Purchaser notifies EME, at least ten (10) Business Days prior to the Closing Date, that it has decided that such Project Notes will not be transferred with the Project Shares as part of the Separately Sold Projects, and (ii) otherwise, to EME or its parents or Subsidiaries other than Acquired Companies that are not included in the Separately Sold Projects (including the Project Notes, the "Owner Notes"), including the obligations set forth on Schedule 1.1, to the extent that such notes or other obligations are not otherwise paid, retired, canceled, contributed to the capital of or otherwise transferred to MEC BV or any of its Wholly Owned Subsidiaries or Rapid Energy prior to the Closing Date.

1.2 Assignments Among Sellers. This Agreement shall not constitute an agreement to assign any asset or to assume any liability between or among any Sellers.

1.3 Excluded Items.

(a) Notwithstanding anything in Article I to the contrary, the companies and assets set forth on Schedule 1.3 and any and all Liabilities related thereto (together, the "Excluded Items") are excluded from this Agreement and from the Contemplated Transactions and shall not be acquired by the Purchaser under this Agreement. Accordingly, and in accordance with Section 6.22, the Sellers will sell, transfer or otherwise dispose of, or will procure the sale, transfer or disposal of, the Excluded Items prior to the First Closing so that none of the Acquired Companies shall have any direct or indirect ownership interest in, or any other Liability (whether actual or contingent and including any Liability for Tax) for or in relation to, the Excluded Items as of the First Closing, except for such Liabilities for which EME shall indemnify the Purchaser Parties in accordance with clauses (ii) and (vi) of Section 11.3(a) and with Section 11.5(a) for any failure to comply with the foregoing.

(b) Without limiting the provisions of Section 1.3(a) or Section 6.22, the Parties acknowledge that EME has entered into a separate agreement with a third party to sell the Excluded Contact Companies (the "Contact Sale Transaction"). In order to facilitate the execution of the Contact Sale Transaction

separately from the Contemplated Transactions, EME shall cause the transfer of the Excluded Contact Companies to a Wholly Owned Subsidiary of MEHI in exchange for a payment obligation (the "Contact Transfer Payment Obligation") from MEHI to the seller of the Excluded Contact Companies. The Contact Transfer Payment Obligation shall conform to the terms of the payment obligation described in Schedule 1.3(b) (a "Payment Obligation"), mutatis mutandis. Such transfer (the "Contact-MEHI Transfer") will occur in advance of both the First Closing hereunder and consummation of the Contact Sale Transaction. The principal amount of the Contact Transfer Payment Obligation will be equal to $750,000,000, and the Contact Transfer Payment Obligation will in any event be due and payable, at the option of the holder, upon the Second Closing or any other sale of MEC BV.

1.4 Confidentiality Agreements. On the Closing Date, EME shall designate the Purchaser Parties and any applicable Purchaser Designees as intended third party beneficiaries under the confidentiality agreements entered into between EME and certain third party prospective bidders in connection with the Auction Process (collectively, the "Auction Confidentiality Agreements") insofar as the Auction Confidentiality Agreements pertain to (a) any Review Material (as defined in such Auction Confidentiality Agreements) or other confidential or proprietary information of, involving or otherwise related to the Acquired Companies, Projects, Owner Notes or EME Guarantees or any of the Purchaser Parties or any Purchaser Designees, (b) any employees of any Acquired Company, or (c) any covenants, agreements or indemnities set forth in such Auction Confidentiality Agreements involving or otherwise related to, any Acquired Company, Project, Owner Notes or EME Guarantees, or any transaction or potential transaction pertaining thereto and covered by such Auction Confidentiality Agreements. Promptly after the Effective Date, but in no event later than five (5) Business Days thereafter, EME shall require that each other Person who is a party to an Auction Confidentiality Agreement shall promptly return to EME or destroy any Review Material, and all written or recorded copies thereof and written material, memoranda, notes, copies, excerpts and other writings or recordings whatsoever based upon, containing or otherwise reflecting any Review Material, subject to the terms of the applicable Auction Confidentiality Agreement, save that the provisions of this Section 1.4 shall not apply to any information concerning any Excluded Item, including the Excluded Contact Companies, or information concerning Valley Power (insofar as Review Material with respect to it has been provided to the proposed purchaser of the Excluded Contact Companies) or information concerning any Subsidiary of EME that is not an Acquired Company. EME shall not waive or modify any provisions of any Auction Confidentiality Agreement that relate to any Review Material pertaining to any of the Acquired Companies or the Projects and shall use Commercially Reasonable Efforts to enforce the Auction Confidentiality Agreements with respect to such Review Material.

1.5 Assignment of Rights and Obligations to Purchaser Designees. For purposes of this Agreement, the term "Purchaser Designee" shall refer to any Subsidiary of any Purchaser Party and any constituent partner, joint venturer or participant in any Purchaser Party (if such Purchaser Party is a partnership, joint venture, consortium or other association or organization) or Subsidiary thereof to whom any of the Purchaser's rights and obligations hereunder are assigned in compliance with the requirements of this Section 1.5. Notwithstanding any contrary provisions contained herein, the Parties agree that, at any time after the Effective Date, the Purchaser, in its sole discretion, may assign any or all of its rights and obligations arising under this Agreement or any Related Agreement to one or more Purchaser Designees, provided that no such assignment shall relieve any Purchaser Party of any Liability to any Seller or its Affiliates hereunder or under any Related Agreement, and provided further that the following shall apply:

(a) The Purchaser shall provide EME with prompt written notice of any such assignment.

(b) No such assignment shall be effected if the making of the assignment will result in the inability or reduced ability of any Seller, Acquired Company or Purchaser Party to obtain any consent or authorization in connection with the Contemplated Transactions or will create economic

detriment to any Seller or its Affiliates arising from the consummation of the Contemplated Transactions.

(c) Each Purchaser Designee shall irrevocably appoint the Purchaser as an authorized representative and agent authorized to act for, to bind and to receive notices and payments on behalf of such Purchaser Designee in all matters arising from or related to this Agreement, any Related Agreements or the Contemplated Transactions.

(d) Irrespective of any such assignment or the identity of the party or parties executing any Related Agreements:

(i) The Purchaser shall remain liable to the EME Guarantee Parties and relevant third parties with respect to any EME Guarantees which are not released prior to the Closing Date in the manner and to the extent described in Section 6.14, and the Purchaser shall remain liable to the Sellers and their Affiliates with respect to any other covenant, obligation or liability to any Seller or its Affiliates hereunder or under any Related Agreement that is transferred to, or undertaken by, a Purchaser Designee, including the payment of all sums due to any Seller or its Affiliates hereunder or under any Related Agreement, it being understood that all such covenants, obligations and liabilities shall constitute the direct and primary obligation of the Purchaser to the Sellers and their Affiliates (and to third parties in the case of the EME Guarantees and, subject to Section 6.14, to the issuers of pertinent letters of credit); and

(ii) Without limiting the generality of the foregoing, if and to the extent that the application of any principle of Law could construe the retention by the Purchaser of the direct and primary obligation to perform any and all obligations, liabilities or covenants assigned to or assumed or undertaken by a Purchaser Designee to be a guaranty by the Purchaser of the Purchaser Designee's performance, then the Purchaser hereby irrevocably, absolutely and unconditionally guarantees to each Seller and each of its Affiliates the full, prompt and faithful performance by such Purchaser Designee of all covenants and obligations to be performed by such Purchaser Designee under this Agreement and any Related Agreement assigned to or entered into by such Purchaser Designee.

(e) The Purchaser further hereby agrees that a separate Action or Actions may be brought and prosecuted against it for any covenant, obligation or liability assigned to or undertaken by a Purchaser Designee for which the Purchaser remains liable under Section 1.5(d), whether Action is brought against the pertinent Purchaser Designee or whether such Purchaser Designee is joined in any such Action or Actions (the Purchaser hereby waiving any right to require any Seller or any Affiliate thereof to proceed against any Purchaser Designee).

(f) The Purchaser hereby authorizes each Seller and each of its Affiliates, without notice and without affecting the Purchaser's liability hereunder, from time to time to (i) renew, compromise, extend, accelerate or otherwise change the terms of any obligation of any Purchaser Designee hereunder or under any Related Agreement, (ii) take and hold security for the obligations of any such Purchaser Designee and exchange, enforce, waive and release any such security, and (iii) apply such security and direct the order or manner of sale thereof as such Seller or Affiliate, as the case may be, in its sole discretion may determine, in the case of each of clauses (i) and (ii) subject to obtaining the prior written agreement of the relevant Purchaser Designee.

(g) Each Purchaser Party hereby further waives:

(i) Any defense that may arise by reason of the incapacity or lack of authority of any Purchaser Designee;

(ii) Any defense based upon any Law which provides that the obligations of a surety must be neither larger in amount nor in other respects more burdensome than those of the principal;

(iii) Any duty on the part of any Seller or any Affiliate thereof to disclose to any Purchaser Party any facts that any Seller or any Affiliate thereof may now or hereafter know about any Purchaser Designee;

(iv) Any right to subrogation, reimbursement, exoneration or contribution or any other rights that would result in any Purchaser Party being deemed a creditor of any Purchaser Designee under any Bankruptcy Law or any other Law, in each case arising from the existence or performance of obligations of any Purchaser Designee hereunder or under any Related Agreement; and

(v) Any and all defenses any Purchaser Party may have by reason of any election of remedies by any Seller or any Affiliate thereof, as well as diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of any Purchaser Designee, protest, notice and all demands, and each Purchaser Party covenants that its guarantee of the obligations of any Purchaser Designee hereunder or under any Related Agreement shall not be discharged except by complete performance by such Purchaser Designee of its obligations under this Agreement and the Related Agreements.

ARTICLE II.
PURCHASE PRICES, PAYMENTS AND ADJUSTMENTS

2.1 Purchase Price. The purchase price to be paid for the Shares and the Owner Notes shall include the assumption of the EME Guarantees and issuance of replacement letters of credit referred to in Section 6.14 and otherwise (i) for the Project Shares and the Project Notes, shall be a United States Dollar amount for each Separately Sold Project equal to the applicable United States Dollar purchase price listed on Schedule 2.1 (the "Project Allocation Schedule") opposite the name of each Separately Sold Project (each a "Project Purchase Price" and, as the same may be adjusted from time to time pursuant to the provisions of this Agreement adjusting a Separately Sold Project Price, including this Section 2.1, Section 2.4, Section 2.5, Section 3.2, or Section 8.1(c), the "Separately Sold Project Price"), and (ii) for the other Shares and Owner Notes, shall be a United States Dollar amount equal to (x) the sum of all Project Purchase Prices (including Separately Sold Projects), and (y) an amount equal to the principal of and any accrued but unpaid interest on the Contact Transfer Payment Obligation (together with the Project Purchase Prices, the "Aggregate Purchase Price"), as the same may be adjusted from time to time pursuant to the provisions of this Agreement adjusting such Aggregate Purchase Price (or its component Project Purchase Prices), including this Section 2.1, Section 2.4, Section 2.5, Section 3.2, or Section 8.1(c) ("Net Aggregate Purchase Price"). Without prejudice to Section 7.8(a), each Purchase Price shall be calculated and paid without reduction or offset for any transfer, documentary, sales, value-added, goods and services, use, stamp, registration or other similar Taxes, or for any Taxes required by Law to be withheld, deducted from, or paid with respect to, such Purchase Price. The Sellers and the Purchaser agree that each Project Purchase Price set forth on the Project Allocation Schedule is a fair market value allocation of the unadjusted Purchase Price in relation to the pertinent Project and to this end further agree if, by reason of any Project Partial Termination Event pursuant to Section 9.3, any of the Projects listed on the Project Allocation Schedule shall no longer be subject to acquisition under this Agreement, then the Aggregate Purchase Price for all purposes (including Section 2.3) shall be automatically reduced in accordance with Section 2.4, and the Project Purchase Prices for the Projects that remain subject to acquisition under this Agreement shall remain in full force and effect (but subject to adjustment as specified in this Agreement).

2.2 Allocations. EME, on behalf of itself and the other Sellers, and the Purchaser, on behalf of itself and any Purchaser Designees, have agreed that the portion of the Aggregate Purchase Price allocable to the Contact Transfer Payment Obligation is equal to the principal of and accrued interest, if any, thereon and that the remainder of the unadjusted Aggregate Purchase Price is allocable among the Shares and the Owner Notes as set forth in Schedule 2.2 (the "Allocation"), provided that in the case of the Separately Sold Projects, the Allocation shows only an allocation among the Project Notes and Project Shares of each Project in the aggregate and not among the Project Shares or the Project Notes, as the case may be. Following the Effective Date and prior to the First Closing, EME and the Purchaser shall utilize Commercially Reasonable Efforts to agree upon and amend the Allocation to further allocate the amounts set forth in the Allocation among the various Project Shares and Project Notes, if any, included in each Separately Sold Project. Each of the Sellers on the one hand and each of the Purchaser and any Purchaser Designees on the other shall (A) be bound by the Allocation for all purposes, including for determining any Taxes; (B) prepare and file, and cause its Affiliates to prepare and file, all Tax Returns on a basis consistent with the Allocation; and (C) take no position, and cause its Affiliates to take no position, inconsistent with the Allocation on any applicable Tax Return or in any proceedings before any Tax Authority, or otherwise, subject in any such case to any adjustment to the Allocation under this Section 2.2. In the event the Allocation is audited or disputed by any Tax Authority, or otherwise, the Party receiving notice thereof shall promptly notify the other Parties hereto. Each of the Sellers and the Purchaser, on behalf of itself and any Purchaser Designees, acknowledge and confirm that the Allocation was determined at arm's length based on fair market values and the willingness of EME and the Purchaser to proceed with the Contemplated Transactions on the basis set out in this Agreement even if not all the Projects are included in the transactions consummated hereunder as described in Section 2.1. If an unadjusted Purchase Price is adjusted, whether pursuant to Section 2.5 or otherwise, then the Allocation will be amended as follows, it being understood that any adjustment to a Separately Sold Project Price shall be reflected in a corresponding adjustment to the Aggregate Purchase Price:

(a) if the adjustment occurs because any Owner Notes are paid, retired, canceled or contributed to the capital of, or otherwise transferred to, MEC BV or any of its Wholly Owned Subsidiaries or Rapid Energy prior to the Closing Date, then any amounts allocated to such Owner Notes in the Allocation shall be reduced by the amount paid, retired, canceled, transferred or contributed (as the case may be) in respect thereof and the amount allocable to the Shares correspondingly increased;

(b) if the adjustment occurs for any other reason, then the amounts shown in the Allocation in respect of the Shares shall be increased or reduced (as the case may be) by (in aggregate) an amount equal to the adjustment to the unadjusted Purchase Price, such increase or reduction to be apportioned between the different categories of Shares shown in the Allocation by reference to the proportion which the amount allocated to a category of Shares in the Allocation bears to the total amount allocated to all of the Shares in the Allocation (in each case prior to the operation of this Section 2.2(b)); and

For the avoidance of doubt, any adjustment to an unadjusted Purchase Price pursuant to Section 2.5(a)(iii) arising from the amount of Net Operating Capital on the Closing Date shall not require or result in any change in a Project Purchase Price allocation.

2.3 Payment. At the First Closing, the Separately Sold Project Price for each Separately Sold Project will be paid by delivery from the Purchaser (or a Purchaser Designee) to MEC BV, acting on behalf of the Project Sellers, of a Payment Obligation issued to the applicable Project Seller in the principal amount of the Separately Sold Project Price. At the Second Closing, the Purchaser will (or

will cause any applicable Purchaser Designee to) pay the Net Aggregate Purchase Price to EME (for itself and on behalf of the other Sellers) in accordance with Section 3.2. The Sellers hereby irrevocably authorize EME to receive any amount due to them under this Section 2.3 and the receipt of any such amount in the account referred to in the preceding sentence shall be a good, valid and effectual discharge for the Purchaser in respect of such amount and the Purchaser shall have no obligation relating to the distribution of any such payment to or among the Sellers.

2.4 Project Partial Termination Purchase Price Adjustment. If this Agreement is partially terminated pursuant to Section 9.3 with respect to any Project prior to the Closing Date, then the Aggregate Purchase Price payable pursuant to Section 2.3 shall be automatically reduced in an amount equal to the Project Purchase Price for each such Project set forth on the Project Allocation Schedule (including any other adjustments related thereto).

2.5 Other Purchase Price Adjustments.

(a) In addition to the adjustments provided for in Section 2.4 and elsewhere in this Agreement, the Aggregate Purchase Price shall be subject to adjustment as follows:

(i) The Aggregate Purchase Price will be decreased by the greater of (A) an amount equal to ninety percent (90%) of the sum of the Estimated Project Distributions for all of the Projects (other than any Projects in respect of which there has occurred a Project Partial Termination Event) for the period from (and including) January 2004 and ending at the conclusion of the month immediately prior to the month in which the Closing Date falls, and (B) the aggregate of all (x) Distributions of money, financial obligations or tangible assets made, directly or indirectly, on or after January 1, 2004 and ending on the Closing Date, plus (y) if and only if such Distributions are less than the percentage of Estimated Project Distributions specified in clause (A) above, such additional Distributions (but only, together with actual Distributions, up to such percentage) included in such Estimated Project Distributions for the months in question that EME demonstrates to Purchaser's reasonable satisfaction have been temporarily delayed and will be paid within three (3) months following the Closing Date, provided that for purposes of this Section 2.5(a)(i), Distributions shall be limited to those made (including those temporarily delayed) by (1) any of the entities identified on Schedule 2.5 (each a "Project Operating Company"), to (2) EME or a Subsidiary of EME that is not a Project Operating Company, and provided further that there shall be excluded (I) any Distribution in respect of which substantially concurrently there is repaid to the Project Operating Company, by set-off or otherwise, an advance of money previously made by the Project Operating Company and any interest thereon (including the Distribution of any receivable arising from such an advance), provided that this exclusion (I) shall only apply to the extent the amount repaid is equal to the amount of such Distribution, and (II) any Distribution within clause (ii), (iii) or (v) of the definition of Permitted Transfers, it being understood that for purposes of making calculations under this Section 2.5(a)(i), the amount of any Distribution shall be reduced by withholding Taxes, if any, imposed upon the payment or receipt thereof;

(ii) The Aggregate Purchase Price will be increased by the 2004 general and administrative overhead expenses set forth in Section 2.5(a)(ii) of Schedule 2.5 allocated to all the Project Operating Companies that are Acquired Companies, multiplied by a fraction, the numerator of which shall be the number of days between and including January 1, 2004 and the Closing Date and the denominator of which shall be 366; and

(iii) The Aggregate Purchase Price will be increased or decreased, as the case may be, by the sum of the Net Operating Capital, as of the Closing Date, of all Acquired Companies that are not either (x) Project Operating Companies or (y) listed on Schedule 2.5 as Excluded Acquired Companies, provided that under no circumstances shall the Aggregate Purchase Price be increased by an amount in excess of $75,000,000 by reason of the operation of this clause (iii) of

Section 2.5(a). The term "Net Operating Capital" shall mean cash and cash equivalents, including restricted cash that provides credit support described in Section 6.14(c), plus (subject to Section 2.5(g)) current accounts receivable (but excluding prepayments for which the Purchaser would not get the benefit) of any Acquired Company other than a Project Operating Company from Persons other than Seller Parent or a Subsidiary thereof or a Project Operating Company, minus current accounts payable, accrued liabilities and provisions (including in respect of interest) of such Acquired Company to Persons other than Seller Parent or a Subsidiary thereof that is not Project Operating Company, but excluding therefrom (A) any Taxes (which are governed by Article VII and Section 11.5) and (B) the Owner Notes. Net Operating Capital shall be based solely upon the internal records of, and valuation and accounting methods customarily used by, the Sellers, absent manifest error.

(b) No less than ten (10) nor more than twenty (20) Business Days before the Closing, EME shall deliver to the Purchaser a certificate executed on EME's behalf by a responsible officer setting forth EME's good faith estimate, in reasonable detail, of the aggregate amount of any adjustments to the unadjusted Aggregate Purchase Price arising under this Section 2.5 (the "Estimated Aggregate Adjustment Amount"), and, for purposes of payments to be made at the Second Closing, the Aggregate Purchase Price shall be adjusted by one hundred percent (100%) of the Estimated Aggregate Adjustment Amount. Such certificate shall also include a calculation of the portion of the Estimated Aggregate Adjustment Amount that is also fairly allocable to each Separately Sold Project Price, employing the principles set forth above to the Project Specific Acquired Companies that comprise each Separately Sold Project mutatis mutandis, and each Separately Sold Project Price shall likewise be adjusted by one hundred percent (100%) of such allocated amount.

(c) As soon as reasonably practicable after the Closing Date (and in no event later than the day which is ten (10) Business Days following expiration of four (4) months after the Closing Date (such day the "Expiry Date") or earlier than the day which is ten (10) Business Days following expiration of three (3) months after the Closing Date), the Purchaser shall provide a certificate to EME, and EME may provide a certificate to the Purchaser, executed on the delivering Party's behalf by a responsible officer, indicating whether or not the delivering Party agrees that the actual adjustment required to be made to the unadjusted Aggregate Purchase Price under this Section 2.5 is equal to the Estimated Aggregate Adjustment Amount or that the Party has proposed modifications to EME's original Estimated Aggregate Adjustment Amount.

(d) If the Purchaser and EME notify their agreement that the actual adjustment required to be made to the unadjusted Aggregate Purchase Price arising under this Section 2.5 is equal to the Estimated Aggregate Adjustment Amount, or if EME and the Purchaser fail to give any notification under Section 2.5(c) on or prior to the Expiry Date, then the Estimated Aggregate Adjustment Amount (and the portion thereof that is also allocable to the Separately Sold Project Price) shall be final and binding on the Parties as the actual amount of any adjustment required to be made to the unadjusted Aggregate Purchase Price (and to the Separately Sold Project Price) under this Section 2.5.

(e) If the Purchaser notifies EME, or EME notifies the Purchaser, on or prior to the Expiry Date that it believes that the actual adjustment required to be made to the unadjusted Aggregate Purchase Price under this Section 2.5 is not equal to the Estimated Aggregate Adjustment Amount, or EME claims amounts under Section 2.5(h), then (A) such Party shall also provide the other with its proposed adjustments to the Estimated Aggregate Adjustment Amount, together with an explanation of such adjustments, and (B) Purchaser and EME shall attempt to resolve any disagreement regarding the actual amount of any adjustments required to be made to the unadjusted Aggregate Purchase Price under this Section 2.5 within thirty (30) days after the delivery of the pertinent certificate or certificates under Section 2.5(c) and, if they fail to do so, then either the Purchaser or EME may refer the matters in dispute concerning such adjustments to an Expert to be determined in accordance with Section 12.10. The actual aggregate adjustment required to be made to the unadjusted Aggregate Purchase Price

under this Section 2.5 as agreed between the Purchaser and the Seller or as determined by the Expert (the "Final Aggregate Adjustment Amount") shall be final and binding on the Parties (including any portion thereof that is also allocable to the Separately Sold Project Price).

(f) The difference between the Final Aggregate Adjustment Amount and the Estimated Aggregate Adjustment Amount (together with interest on such amount at a rate of 2.5 percent above the base rate from time to time of NatWest Bank plc (accrued daily and compounded monthly) for the period from the Closing Date to the date of payment) will be paid (1) by EME (for itself and on behalf of the other Sellers) to the Purchaser if the Aggregate Purchase Price payable at Closing would have been less than the actual amount paid at that time in respect of the Aggregate Purchase Price had the Estimated Aggregate Adjustment Amount been equal to the Final Aggregate Adjustment Amount, or (2) by the Purchaser to EME (for itself and on behalf of each of the other Sellers) if the Aggregate Purchase Price payable at Closing would have been higher than the actual amount paid at that time in respect of the Aggregate Purchase Price had the Estimated Aggregate Adjustment Amount been equal to the Final Aggregate Adjustment Amount, in either case within five (5) Business Days following agreement or determination of the Final Aggregate Adjustment Amount.

(g) The Purchaser may, by notice in writing to EME given at the same time as the certificate referred to in Section 2.5(c), require that an amount equal to any current account receivable of an Acquired Company that is not a Project Operating Company as of Closing which such Acquired Company has been unable to collect in the period prior to the Expiry Date be disregarded for the purposes of calculating Net Operating Capital provided that the Purchaser shall arrange for the assignment to EME (as principal and as agent for the other Sellers) of any such receivable and the assignee shall be free to collect the same.

(h) Notwithstanding anything to the contrary in this Section 2.5, the Parties agree that if (i) any amounts were excluded from the Estimated Aggregate Adjustment Amount as of the Closing Date, pursuant to Section 2.5(a)(i), due to EME's failure to demonstrate to Purchaser's reasonable satisfaction that Distributions in such amounts had been temporarily delayed and would have been paid within three (3) months following the Closing Date, (ii) the amount calculated in Section 2.5(a)(i)(A) exceeds the amount calculated in Section 2.5(a)(i)(B) and (iii) during such three (3) month period following the Closing Date, Distributions were received by Purchaser or any Subsidiary thereof that is not a Project Operating Company (replacing the term "EME" with the term "Purchaser" in the definition of "Distribution" in Article X, mutatis mutandis), then an amount equal to 100 percent (100%) of any such Distributions received by Purchaser or any of such Subsidiaries up to the amount of such excess referred to in clause (ii) above (together with interest on such amount at a rate of 2.5 percent (2.5%) above the base rate from time to time of NatWest Bank plc (accrued daily and compounded monthly) for the period from the Closing Date to the date of payment) will be paid by the Purchaser to EME (for itself and on behalf of each of the other Sellers) pursuant to the other provisions of this Section 2.5.

3.6 Use of Escrow. The Parties acknowledge that it may facilitate their objectives hereunder to consummate the Contemplated Transactions to occur at a Closing through an escrow. In such escrow, the Parties may agree to have certain of the Acquired Companies and related assets purchased, sold and released from the escrow with the allocable portion of the Aggregate Purchase Price applicable thereto before the Project Shares or the Shares of MEC BV and Rapid Energy are sold or otherwise to accomplish in an orderly and more precise manner certain aspects of the Contemplated Transactions before completing others. If EME and the Purchaser agree to any such escrow arrangements, then the Parties shall (i) execute joint escrow instructions and any agreements necessary to implement the Contemplated Transactions or to satisfy any relevant Laws with respect thereto, (ii) jointly designate an escrow agent and (iii) deposit a fully executed copy of this Agreement with the escrow agent together with such joint escrow instructions and implementation agreements.

If a Closing is to be consummated through the escrow agent, then the Parties shall deliver to the escrow agent, upon the opening of escrow, the funds and the instruments of sale, assignment, conveyance and assumption as are called for to be delivered by them at the Closing, and the escrow

agent shall thereafter deliver and distribute such funds and instruments out of escrow, make such recordations, and engage in such other actions and activities as are set forth in the joint escrow instructions. Unless otherwise expressly specified in the escrow instructions or such implementing agreements, for purposes of this Agreement, all conditions to such Closing shall be deemed satisfied or waived as of the opening of such escrow, the transactions to occur in escrow shall be effective as provided in the joint escrow instructions, and time periods from and after the Closing Date shall be measured as of the date such escrow is opened. The Seller Parties, on the one hand, and the Purchaser Parties, on the other hand, agree to consider in good faith making Commercially Reasonable Efforts with respect to joint actions (including the opening of an escrow pursuant to this Section 3.6) and potential amendments to this Agreement proposed by each other that achieve and facilitate the achievement of the objectives of this Agreement, provided that, in each Party's sole discretion, such actions or amendments do not impose or risk imposing additional burdens on such Party or its Affiliates or create any material delay or risk to consummating the Contemplated Transactions, and provided further that a Party's effectuation of such Commercially Reasonable Efforts or entry into any amendment proposed by another Party shall be subject to the first Party's prior written consent, which may be withheld in its discretion.

3.7 Support and Services; Transition Arrangements. The support companies identified on Schedule 3.7 (the "Support Companies") have traditionally provided indirect overhead and management services (including operating, financial, accounting, tax, administrative, legal, agency, government relations and technical services) (collectively, the "Support Services") to certain Project-Specific Acquired Companies of more than one of the Projects. If a Project becomes subject to a Project Partial Termination Event in accordance with the terms of Section 9.3 such that the ownership of any such Project will be separated from the ownership of the applicable Support Company, then EME may, in connection therewith, request that Purchaser provide, or cause the applicable Support Companies to provide, and the Purchaser may, in connection therewith, request that EME provide or cause the applicable Support Company to provide those Support Services that have been historically provided to the Project-Specific Acquired Companies in the manner previously provided and utilizing such Retained Employees, Ex-▇▇▇ Employees and other employees as are employed by the Support Company and such Support Services will be provided by such Support Companies on commercially reasonable terms and conditions, including duration, scope and cost (taking into account the historical intercompany cost charged by the applicable Support Company in the Ordinary Course of Business prior to the Effective Date). In the event of any such request, the Parties will work cooperatively to document the terms and conditions of the provision of such Support Services as soon as is reasonably practicable. For the purposes of this Agreement relating to the Project known as "First Hydro" or the Project known as "Spanish Hydro" (A) all of the assets and undertaking comprising the in-country support office at Deeside and the regional office in London (as referred to on page 19 of the Confidential Information Memorandum), and any staff located at either of those offices, shall be deemed to relate exclusively to the Project known as "First Hydro" and (B) all of the assets and undertaking comprising the in-country support office at Barcelona (as referred to on page 19 of the Confidential Information Memorandum), and any staff located there, shall be deemed to relate exclusively to the Project known as "Spanish Hydro".

The Purchaser acknowledges that EME intends to sell entities and assets in the Auction to third parties which are (1) unrelated to the Contemplated Transactions, or (2) Excluded Items. In order to avoid hindering EME's right to engage in such transactions in connection with the Auction, if any Acquired Company has a preemptive or purchase right, or right of approval, with respect to or as a result of any such sale or attempted sale by EME in the Auction, the Purchaser agrees that following the Closing, it and its Affiliates will not exert their control over any of the Acquired Companies in order to exercise any such preemptive or purchase right or in order not to give in a timely manner any such approval, so as to interfere with or hinder such transactions by EME with such third parties.

In connection with this Section 6.12, each Purchaser Parent unconditionally waives: (A) any right to receive demands, protests or other notices of any kind or character whatsoever, as the same may pertain to any Purchaser Party or any Purchaser Designee, (B) any right to require any Seller to proceed first against any other Purchaser Party or any Purchaser Designee or to exhaust any security held by it or to pursue any other remedy, (C) any defense based upon an election of remedies by any Seller, (D) any duty of any Seller to advise the Purchaser Parents of any information known to it regarding any Purchaser Party or Purchaser Designee or its ability to perform under this Agreement or any Related Agreement, and (E) all suretyship and other defenses of every kind and nature.

(c) The obligations of the Purchaser Parents under this Section 6.12 shall be automatically reinstated if and to the extent that for any reason any payment or other performance by or on behalf of any Purchaser Party or any Purchaser Designee in respect of the Purchaser Obligations is rescinded or must be otherwise restored, and each Purchaser Parent agrees that it will indemnify EME and the other Sellers on demand for all costs and expenses (including reasonable attorneys fees and expenses) incurred by any of them in connection with such rescission or restoration. If in connection with the foregoing, any Seller or its Affiliates is required to refund part or all of any payment of any Purchaser Party or any Purchaser Designee, such payment by any of them shall not constitute a release of any Purchaser Parent from any liability under this Section 6.12, and each Purchaser Parent's liability under this Section 6.12 shall be reinstated to the fullest extent allowed under Applicable Law and shall not be construed to be diminished in any manner.

(d) This Section 6.12 shall survive the Closing and any termination pursuant to Article IX hereof and shall remain in full force and effect, subject to the provisions of Section 6.12(c).

6.13 Lease for Elwy House at Deeside. Within a reasonable time after the Effective Date, but in no event later than December 23, 2004, EME shall cause the tenant of those leased premises located at Elwy House in Deeside to send a written notice of termination of lease, effective as of June 23, 2005, to the landlord of such premises. The Purchaser (or the applicable Purchaser Designee) shall be responsible for any costs and fees associated with such termination and, if assessed prior to the Closing, shall remit the amount of such costs and fees to EME or any Person designated by EME promptly after demand by EME therefor.

6.14 Guarantees and Credit Support by EME.

(a) EME and certain of its Non-Acquired Subsidiaries (the "EME Guarantee Parties") are guarantors or obligors with respect to certain obligations related to the Acquired Companies as set forth on Schedule 6.14 (collectively, the "EME Guarantees"). Prior to the Closing, the Purchaser shall use its Commercially Reasonable Efforts to cause the EME Guarantee Parties to be released as guarantors under the EME Guarantees and if the Purchaser is unsuccessful in causing the EME Guarantee Parties to be released as guarantors under the EME Guarantees, then the Purchaser shall indemnify each EME Guarantee Party in respect of any liability which it may suffer under the EME Guarantees after the Closing Date.

(b) Schedule 6.14 sets forth a list of certain letters of credit in favor of the lenders to Project Operating Companies, or to parties representing such lenders, the issuance of which were arranged by EME and certain of its Subsidiaries under their existing credit facilities. Prior to or concurrently with the Closing, the Purchaser shall cause to be issued under its credit facility letters of credit in replacement of those set forth on Schedule 6.14 and shall use its Commercially Reasonable Efforts to cause the return to EME and its Subsidiaries of the letters of credit which are being so replaced and shall reimburse EME or the relevant Subsidiary for the amount, if any, of any drawing made on the letters of credit being so replaced after the Closing Date and prior to their return to EME or the relevant Subsidiary.

(c) Certain of the Acquired Companies have provided cash as credit support for the issuance of letters of credit (e.g., in support of the trading activities of First Hydro) and for other assurances of performance (e.g., in the case of P.T. Adaro), as described on Schedule 6.14. Notwithstanding any other provision hereof, any such cash, and any other cash or cash equivalents available to an Acquired Company on a similarly restricted basis, shall be treated as cash or a cash equivalent for purposes of Section 2.5(a)(iii) .

(d) The Sellers will procure that the benefit of any indemnity given by an Acquired Company in favor of an EME Guarantee Party in connection with an EME Guarantee is assigned to MEC BV prior to the Closing.

6.15 Guarantees and Credit Support by Acquired Companies.

(a) Between the Effective Date and the Closing Date, each of the Sellers shall use its Commercially Reasonable Efforts to cause any Acquired Company which is guarantor of any obligations of EME or any of its Non-Acquired Subsidiaries (each such Acquired Company an "AC Guarantee Party") to be released as guarantors of such obligations as of the Closing, and, if the Sellers are unsuccessful in causing any AC Guarantee Party to be released as guarantor of such obligations, then EME shall indemnify the relevant AC Guarantee Party in respect of any liability which it may suffer after Closing under any of the guarantees given by it in connection with any obligations of EME or any of its Non-Acquired Subsidiaries.

6.16 Liquidation of Mission Hydro Partnership. Nothing in this Agreement shall restrict or limit the ability of EME and its Subsidiaries to liquidate the Mission Hydro Partnership or to liquidate or redeem the interest of Mission Energy Wales Company therein using any reasonable means selected by EME, provided that at the Closing Date MEC BV and its Wholly Owned Subsidiaries shall directly or indirectly own one hundred percent (100%) of the record and beneficial ownership of the equity interests in the Projects known as First Hydro and ▇▇▇ ▇▇▇▇ B.

6.17 Miscellaneous Assets. Without limiting the provisions of Section 4.18, in the event that there are physical assets held by EME or by Non-Acquired Subsidiaries that are customarily used in and located at the businesses of the Project-Specific Acquired Companies, EME shall cause such physical assets or the benefits thereof to be contributed, assigned, licensed or otherwise transferred to MEC BV or the pertinent Project-Specific Acquired Company, without charge to the Purchaser or to any Acquired Company, prior to Closing. EME shall also cause copies of books and records, or pertinent portions thereof, that relate solely to the Controlled Acquired Companies and that are maintained by EME or a Non-Acquired Subsidiary to be delivered to the Purchaser at Closing, subject to confidentiality or non-disclosure agreements in favor of third parties, if any.

6.18 Political Risk Insurance. If EME or any of its Affiliates have purchased or otherwise possess any Political Risk Insurance Policies covering any Project, subject to Law and the regulations and practices of any applicable Governmental Authority, EME shall use its Commercially Reasonable Efforts to cause the Political Risk Insurance Policies to be assigned to the Purchaser or any Purchaser Designee or to cause the Purchaser or any Purchaser Designee to be named as an additional insured thereunder effective as of the Closing Date, such Commercially Reasonable Efforts to include assisting the Purchaser in discussions with the Overseas Private Investment Corporation relating to such Political

Risk Insurance Policies. If the Political Risk Insurance Policies are terminated because, notwithstanding EME's compliance with its obligations under this Section 6.18, those policies cannot be assigned to the Purchaser or any Purchaser Designee, then any termination costs associated therewith (net of any refunds or other returned amounts) shall be EME's sole responsibility and EME shall indemnify the Purchaser Parties and the Acquired Companies against any such cost, it being understood that such amounts shall not include the cost of any loss of insurance or any replacement insurance policies.

6.19 Preemption Notices. EME agrees to provide to the Purchaser written notice within three (3) Business Days of the receipt of any Preemption Notice and shall keep the Purchaser informed in a timely fashion as to the status and progress of any preemption process following any such receipt of a Preemption Notice.

6.20 Updating.

(a) Without limitation to EME's obligations under Section 6.20(b), EME shall notify the Purchaser of any changes or additions to any of EME's Schedules to this Agreement (including the EME Disclosure Schedule and the Structure Chart contained in Section 4.5(b) of the EME Disclosure Schedule) by the delivery of updates thereof, if any, as of a reasonably current date prior to the Closing, but in no event later than five (5) Business Days prior to the Closing, provided that EME shall continue to deliver updates relating to subsequent changes or additions to any of the Schedules of EME until the Closing. No such updates made pursuant to this Section 6.20(a) shall be deemed to cure any inaccuracy or breach of any representation or warranty made in this Agreement as of the Effective Date nor, for purposes of Section 8.2(a) or Section 11.3(a)(i) (subject to the terms of the second proviso contained therein), the Closing Date, unless the Purchaser specifically agrees thereto in writing, nor shall any such notification be deemed to constitute or give rise to a waiver (whether express or implied) by the Purchaser of any covenant or condition set forth in this Agreement. Without limiting the generality of the foregoing, EME shall notify the Purchaser reasonably promptly of the occurrence of any material casualty, physical damage, destruction or physical loss respecting, or, to the best of the Knowledge of EME, material adverse change in the physical condition of, any Project, subject to ordinary wear and tear and to routine maintenance.

(b) The Sellers and the Purchaser Parties, as the case may be, shall notify each other promptly after becoming aware of (i) the occurrence or non-occurrence of any event whose occurrence or non-occurrence would (A) cause any representation or warranty given by them respectively in this Agreement to be untrue or inaccurate in any material respect at any time from the date hereof to the Closing Date, (B) prevent any condition set forth in Article VIII from being satisfied prior to the Outside Date and (ii) any material failure of any of the Parties or their respective Affiliates or any of their respective Representatives, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder or (C) any material breach or alleged material breach of any Major Contract of which EME has Knowledge.

6.21 Employee Matters.

(a) Retained Employees Who Are Not Ex-▇▇▇ Employees.

(i) Subject to the further terms of this Section 6.21, at and as of the Closing, the Purchaser or its Affiliates shall cause the pertinent Acquired Companies to employ or continue the employment of all of the employees (excluding the Ex-▇▇▇ Employees, the "Existing Employees") of each Acquired Company on the same economic terms and conditions as in effect immediately prior to the Closing Date, unless the Existing Employee chooses to not become so employed (such Existing Employees who continue employment after the Closing Date being referred to in this Agreement as "Retained Employees"). Subject to Applicable Law, the provisions of this Section 6.21 and any existing contractual rights of such Retained Employees, the Retained Employees shall, after the Closing Date, be "at will" employees of the Acquired Companies, unless the Purchaser

and its Affiliates (including the Acquired Companies) make other arrangements. The Parties acknowledge that the terms Existing Employees and Retained Employees do not, nor are they intended in any way to, include any employee of EME.

(ii) Notwithstanding the provisions of Section 6.8 to the contrary, prior to the Closing Date, EME and its Affiliates (including the Acquired Companies) may communicate with the Existing Employees and their representatives and advisers, as the case may be, the terms and conditions of this Section 6.21 and any other provision hereof relating to the employment of the Existing Employees with the Acquired Companies following the Closing Date provided always that none of EME or its Affiliates may make or agree to make any material change to the terms of employment of any Existing Employees without the Purchaser's prior written consent. At least fifteen (15) days prior to the Closing Date, EME shall notify the Purchaser in writing of the name and title of any Existing Employees who have advised EME that they will not continue their employment with the Acquired Companies on or after the Closing Date. Any such Existing Employee shall not continue to be an employee of any Acquired Company from and after the Closing Date and shall not be entitled to any severance payment or other benefit from the Purchaser or any Acquired Company which shall be entitled to be indemnified by EME for all and any such costs, claims, awards or expense in respect of or relating to any such Existing Employee.

(iii) The Purchaser acknowledges that neither it nor any of its Affiliates have notified EME of any decisions regarding the employment of any Retained Employees after the Closing Date, and the Purchaser shall advise EME reasonably promptly of any such decisions made between the Effective Date and the Closing Date.

(iv) After the Closing, the Acquired Companies shall pay, discharge and be responsible for all salary, wages, severance costs, benefits and claims (including workers compensation or other similar benefits and claims) arising out of or relating to the employment of the Retained Employees after the Closing Date, including all liabilities for accrued vacation, holiday, sick leave, salary continuation or short-term disability benefits; the payment of accrued payments or bonuses under any annual or long-term management or employee incentive or bonus plans, programs or arrangements; retirement plan, and non-qualified deferred compensation plan, arising out of or relating to the employment of the Retained Employees after the Closing Date.

(v) The Purchaser acknowledges that after the Closing, all Retained Employees will cease to participate in any and all employee benefit and welfare plans of EME and its Affiliates other than the Benefit Plans of the Acquired Companies listed on the EME Disclosure Schedule. As of the Closing Date, the Purchaser will permit the Retained Employees to continue to participate in the employee benefit and welfare plans or admit them to suitable replacement plans of the Purchaser or its Affiliates (the "Purchaser Plans"). For purposes of vesting, eligibility and calculation of severance payments, all Retained Employees shall retain their respective levels of seniority and shall where applicable receive full credit under the Purchaser Plans for all service with the Acquired Companies prior to the Closing Date. The Purchaser shall where applicable waive all limitations as to preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements under the Purchaser Plans and provide each Retained Employee with credit for any co-payments and deductibles paid prior to the Closing in satisfying any applicable deductible or out-of-pocket requirements under the Purchaser Plans.

(vi) In connection with the Contemplated Transactions, EME has provided severance benefits to the Existing Employees identified on Schedule 6.21 (the "Participating Employees"), for a period of one (1) year following the Closing Date in accordance with the terms and conditions of the EME BV Severance Plans. EME has made copies of the EME BV Severance Plans available to the Purchaser. At the Closing, EME shall assign to the Purchaser, and the Purchaser shall assume from EME, all of EME's obligations to the Retained Employees who are Participating Employees

with respect to any cash severance benefits and outplacement benefits under the EME BV Severance Plans. The payment of any such amounts due and payable under the EME BV Severance Plans with respect to any such Retained Employee who is a Participating Employee shall be the sole obligation of the Purchaser and its Affiliates (including the Acquired Companies) and all costs and expenses associated therewith shall be borne solely by the Purchaser and its Affiliates (including the Acquired Companies); provided, however, EME shall reimburse the Purchaser for any cash severance benefits or outplacement benefits due and payable under the EME BV Severance Plans actually paid to a Retained Employee who is a Participating Employee by the Purchaser or its Affiliates (including any Acquired Company) in connection with the termination or the giving of notice of termination for any reason other than cause by the Purchaser and its Affiliates (including the Acquired Companies) of any such Retained Employee during the four (4) month period immediately following the Closing Date. After the expiration of such four (4) month period, EME shall have no further obligation to reimburse the Purchaser and its Affiliates (including the Acquired Companies) with respect to any amounts owed or paid to a Retained Employee who is a Participating Employee under the EME BV Severance Plans. The Purchaser shall reimburse EME for all cash severance benefits or outplacements benefits, if any, paid to any Existing Employee who advised EME that he would not continue his employment with the Acquired Companies on and after the Closing Date but who thereafter becomes an employee of the Purchaser or any of its Affiliates (including any Acquired Company) within one (1) year following the Closing Date.

(vii) After the Closing Date, Retained Employees who are not Participating Employees may be entitled to receive severance benefits from the Acquired Companies in accordance with applicable Legal Requirements related thereto ("Legal Severance Costs"). After the Closing, the Purchaser and its Affiliates (including the Acquired Companies) shall be solely responsible for the payment of any such Legal Severance Costs with respect to the Retained Employees who are not Participating Employees and all other costs and expenses associated therewith shall be borne solely by the Purchaser and its Affiliates (including the Acquired Companies).

(viii) Subject to EME's reimbursement obligation set forth in this Section 6.21(a)(v) and Section 6.21(a)(vi) above, following the Closing Date, the Purchaser shall be solely responsible for, and shall indemnify, defend and hold the Seller Parties and their Affiliates harmless from and against, any Losses incurred by them arising from or relating to any acts or omissions of the Purchaser or their respective Affiliates (including the Acquired Companies) in connection with the employment or termination of Retained Employees following the Closing.

(b) EME Responsibilities.

(i) Subject to the terms hereof, including Section 6.21(a), EME shall be solely responsible for (A) any incentive compensation, deferred compensation or other benefit under any employee benefit or welfare plan of EME and its Affiliates, other than the Acquired Companies (the "Seller Plans"), and (B) any non-cash severance benefits pursuant to the EME BV Severance Plans for any Retained Employee who as of the Closing Date is eligible for any such benefits and satisfies the conditions for such benefits pursuant to the terms and conditions of such Seller Plans and the EME BV Severance Plans. The foregoing shall not expand the rights of any Retained Employee under any Seller Plan or the EME BV Severance Plans or limit the right of EME or its Affiliates to amend or terminate any Seller Plan.

(ii) EME shall be solely responsible for, and shall indemnify, defend and hold the Purchaser Parties and their respective Affiliates (including the Acquired Companies) harmless from and against, any Losses arising from or relating to (1) any claims made by any Retained Employees with respect to (A) claims arising under, (B) the accrual of or payment of benefits from, or (C) the termination of their participation in, the Seller Plans or the receipt of any non-cash severance

benefits under the EME BV Severance Plans; or (2) any claims in respect of any Seller Plan other than the EME BV Severance Plans.

(iii) Prior to the Closing Date EME and the Acquired Companies shall allow the Purchaser reasonable access to the Existing Employees for the purposes of carrying out assessment and discussing future employment requirements and responsibilities.

(c) Ex-▇▇▇ Employees. Schedule 6.21 identifies certain employees of EME who are ex-patriates and who have direct day-to-day responsibility and oversight for the Acquired Companies (the "Ex-▇▇▇ Employees"). Notwithstanding any provision of the Confidentiality Agreement to the contrary, between the Effective Date and the Closing Date, the Purchaser may solicit the Ex-▇▇▇ Employees for employment with the Purchaser or any of its Affiliates (including the Acquired Companies) after the Closing Date. To the extent any Ex-▇▇▇ Employee becomes an employee or consultant of the Purchaser or any of its Affiliates (including the Acquired Companies) following the Closing Date (each a "Transferred Ex-▇▇▇ Employee"), the Purchaser or its Affiliates (including the Acquired Companies) shall pay, discharge and be responsible for all salary, wages, severance, benefits and claims (including workers compensation benefits or claims) arising out of or relating to the employment of such Transferred Ex-▇▇▇ Employee, including the obligations arising under the EME BV Severance Plans, and none of EME or any of its Affiliates shall be liable for or responsible for any such amounts, following the date such Transferred Ex-▇▇▇ Employee becomes an employee or consultant of the Purchaser or any of its Affiliates (including the Acquired Companies); provided, however, EME shall be solely responsible for any compensation or other benefits under any employee benefit or welfare plan of EME and its Affiliates for any Transferred Ex-▇▇▇ Employee who, prior to becoming a Transferred Ex-▇▇▇ Employee, became eligible for any such benefits and satisfied the conditions for such benefits pursuant to the terms and conditions of such plans. The foregoing shall not expand the rights of any Transferred Ex-▇▇▇ Employee under any such plan or limit the rights of EME or its Affiliates to amend or terminate any such plan. Purchaser shall reimburse EME for any severance benefits paid by EME or its Affiliates to any Ex-▇▇▇ Employee who has not become an employee of the Purchaser or any of its Affiliates (including the Acquired Companies) as of the Closing Date but who thereafter becomes an employee of the Purchaser or any of its Affiliates (including any Acquired Company) within one (1) year following the Closing Date.

(d) No Third-Party Beneficiaries. Nothing in this Section 6.21 or otherwise in this Agreement shall create or confer, nor do the Parties intend to create or confer, upon any Person other than the Parties any rights or remedies, including any rights as a third party beneficiary or otherwise and EME shall so advise the Existing Employees in connection with any communications made pursuant to Section 6.21(a)(ii) above.

6.22 Disposition of Excluded Items. Prior to the Closing Date, the Sellers shall, or shall cause the Acquired Companies to, sell, spin-off or otherwise dispose of the Excluded Items (in each case without Liability, whether actual or contingent and including any Liability for Tax, on the part of any Acquired Company) so that none of the Acquired Companies shall have any direct or indirect ownership interest in, or any other Liability for, the Excluded Items on or as of the Closing Date.

6.23 Foreign Implementing Agreements. As promptly as practicable after the Effective Date, EME and the Purchaser shall cause the Foreign Implementing Agreements, if any, to be prepared and executed by their applicable Affiliates.

6.24 Cancellation of Insurance.

(a) General. Other than the Applicable Policies, the Political Risk Insurance Policies and EME's obligations pursuant to this Section 6.24, EME and its Affiliates shall have no obligation to obtain, maintain or manage any insurance, including the Corporate Insurance Policies (as defined below) relating to any Acquired Company or its respective assets, businesses, employees (including former

employees), directors, officers or other affairs for any period after the Closing Date. As of the Closing Date, the Corporate Insurance Policies will terminate with respect to the Acquired Companies and their respective assets and properties, and the Acquired Companies will cease to be insured thereunder and shall have no right to make claims or receive recoveries thereunder. "Corporate Insurance Policies" means those insurance policies administered or maintained by EME and its parent companies, under which their Affiliates (including prior to the Closing Date, the Acquired Companies), or their respective assets, businesses, employees, directors, officers or other affairs are insured as of the Closing Date, including those insurance policies within the categories described in the EME Disclosure Schedule.

(b) Pre-Closing Insurance Occurrences. After the Closing Date, EME shall use Commercially Reasonable Efforts to retain for the Acquired Companies the right, subject to Applicable Law and the terms of the Corporate Insurance Policies, to make claims and receive recoveries for the benefit of the Acquired Companies under the Corporate Insurance Policies for covered losses arising from occurrences related to the business of the Acquired Companies on or prior to the Closing Date ("Pre-Closing Insurance Occurrences") and to receive recoveries for such claims for the benefit of the Acquired Companies, and to retain for the Acquired Companies the right, subject to the terms of the Corporate Insurance Policies to make claims with respect to Pre-Closing Insurance Occurrences and receive recoveries for such claims directly; provided, however, that Commercially Reasonable Efforts shall not require the conversion of any claims-made policy into an occurrence-based policy, the acceptance of any adverse change in any of the Corporate Insurance Policies, the provision of notice to or the receipt of consent from any insurance carrier or the payment of money by EME or its Affiliates; and provided further, that EME shall have no such obligation with respect to any such policy that provides for coverage to any Acquired Company only if it or they are Affiliates of EME at the time a claim is made to the insurer thereunder. The Purchaser shall, or shall cause the Acquired Companies to, promptly notify EME of any claims with respect to any Pre-Closing Insurance Occurrences made directly and the basis and amount thereof and of any recovery for such claim received directly.

(c) Custody. Notwithstanding any other provisions herein, after the Closing Date, EME and its Affiliates shall retain custody and possession of the Corporate Insurance Policies and any service contracts, claim settlement files, and other insurance records relating to such policies.

6.25 IT Transition. Between the Effective Date and the Closing Date, the Sellers will use Commercially Reasonable Efforts and will co-operate with the Purchaser and its Affiliates to provide for the separation and transition as of the Closing Date of the information technology ("IT") systems (including their support and maintenance) of the Acquired Companies from the Sellers' IT systems so that the Acquired Companies are independent of the Sellers' IT systems, including by implementing the procedures set forth in Schedule 6.25, and in the event that such separation and transition has not been achieved as of the Closing Date, the Parties will use Commercially Reasonable Efforts to complete successfully such separation and transition as soon as reasonably practicable after the Closing Date.

6.26 IPR Shareholder Circular.

(a) Without prejudice to the provisions of Section 6.5(a), which shall apply to the extent reasonably practicable to the UKLA approval process as though such process related to a Merger Control Law, IPR and EME shall cooperate in liaising with the UKLA with a view to satisfying the IPR Shareholder Consent Condition as soon as practicable following the Effective Date. In particular, IPR shall (i) allow the appropriate adviser to EME to participate with IPR's advisers in discussions with the UKLA concerning such condition, (ii) keep EME reasonably informed of the status of the UKLA approval process and (iii) otherwise provide EME with the reasonable opportunity to review and comment on any drafts of the IPR Shareholder Circular, it being understood that IPR shall consider EME's comments in good faith but that the ultimate determination of the contents of the IPR Shareholder Circular shall be for the directors of IPR.

(b) EME will use Commercially Reasonable Efforts to deliver to IPR as soon as reasonably practicable following the Effective Date the financial statements (including the accountants' report thereon) and other information concerning EME and its Subsidiaries (including the Acquired Companies and the Projects) which IPR needs to comply with UKLA rules in connection with the preparation of the IPR Shareholder Circular. Subject to EME's compliance with its obligations under this Section 6.26, as soon as reasonably practicable following the Effective Date IPR shall prepare the IPR Shareholder Circular relating to the approval by Bidder's shareholders of this Agreement and the Contemplated Transactions and cause the IPR Shareholder Circular to be filed with the UKLA. IPR shall use its Commercially Reasonable Efforts to have the IPR Shareholder Circular approved by the UKLA as promptly as practicable after such filing and shall cause the IPR Shareholder Circular to be mailed to its shareholders forthwith following its approval by the UKLA at IPR's sole cost and expense. For the avoidance of doubt, the contents of the IPR Shareholder Circular shall be solely the responsibility of IPR and its directors.

(c) Save as required by Applicable Law (including, for the avoidance of doubt, the requirements of the UKLA) and except for forms of proxy, no other materials (other than miscellaneous non-substantive materials or those jointly approved by the Parties) shall be circulated by IPR to its shareholders in connection with the IPR Shareholders Meeting.

(d) IPR and EME agree to jointly exercise Commercially Reasonable Efforts during the sixty (60) days following the Effective Date to seek the UKLA's authorization and approval for the transactions contemplated pursuant to this Agreement, including the indirect sale of the Minimum Threshold Projects together with any number of Projects in excess of the Minimum Threshold Projects, to be authorized at a single extraordinary general meeting of IPR's shareholders, taking into account the uncertainty over the exact composition of Projects that may be included in the Acquired Companies at Closing.

6.27 IPR Shareholders Meeting(s).

(a) IPR shall procure that any IPR Shareholder Circular shall comply in all material respects with all requirements of Applicable Law and shall include notice of an extraordinary general meeting or meetings of IPR's shareholders (a "IPR Shareholders Meeting") for the sole purpose of seeking their approval of a Resolution (the "IPR Shareholder Approval"), such meeting or meetings to have been duly convened in accordance with IPR's Governing Documents and to be held as soon as possible in accordance with Applicable Law and IPR's Governing Documents following the mailing of an IPR Shareholder Circular.

(d) IPR shall also procure that neither its board of directors nor any committee thereof shall (i) withdraw (or amend or modify in a manner adverse to EME), or publicly propose to withdraw (or amend or modify in a manner adverse to EME), any Recommendation or (ii) recommend, adopt or approve, or propose publicly or recommend, adopt or approve, any Conflicting Proposal (any action described in this clause being referred to as an "Adverse Recommendation Change").

(e) The obligations of IPR in Sections 6.27(b)(i), 6.27(c) and 6.27(d) shall not apply to the extent that the board of directors of IPR concludes in good faith by resolution duly adopted, after consultation with outside legal counsel and a financial adviser of internationally recognized reputation, that compliance with any such Section would constitute a breach of the fiduciary duties of the directors of IPR.

6.28 Conflicting Proposals. Between the Effective Date and the date of satisfaction of the IPR Shareholder Consent Condition, IPR shall not, nor shall it authorize or permit any of its Affiliates or Representatives to, directly or indirectly (i) solicit any inquiries or proposals from or negotiate with, or provide confidential information to, any Person (other than the Purchaser) relating to any Conflicting Proposal or (ii) enter into any agreement with respect to any Conflicting Proposal.

6.29 Fees and Expenses. If (i) this Agreement is terminated by EME pursuant to Section 9.1(f) or (ii) by EME or IPR pursuant to Section 9.1(g), IPR shall promptly, but in no event later than five (5) Business Days after the date of such termination, pay EME the agreed sum of $15,000,000 (the "Inducement Fee"). The Inducement Fee shall be paid by wire transfer of same day funds without reduction or offset for any transfer, documentary, sales, value-added, goods and services, use, stamp, registration or other similar Taxes, or for any Taxes required by Law to the withheld, deducted from, or paid with respect to, the Inducement Fee; provided, however, that notwithstanding the provisions of clause (ii) above, no Inducement Fee shall be payable upon a termination of this Agreement by EME or IPR pursuant to Section 9.1(g) unless, prior to the date of such termination, a Triggering Event shall have occurred.

6.30 Use of Proceeds. EME and its Subsidiaries shall use the net proceeds received in connection with the Contemplated Transactions exclusively (i) to pay (including by way of purchase) indebtedness (including indebtedness of Mission Energy Holdings Company, a Delaware corporation), (ii) to acquire or invest in any power generation facility or energy producing facility, including any related steam fields or oil and gas reserves, (iii) to make capital expenditures or acquire any real, personal or intellectual property, (iv) to acquire equity or debt securities (including, joint venture, partnership or other membership interests) of any Person or (v) to invest in their existing lines of business or to otherwise acquire or develop new lines of business of any type.

6.31 Substitute Insurance.

As soon as practicable following the Effective Date, but in no event later than ten (10) Business Days before the Closing Date, the Sellers shall provide Purchaser with a list in reasonable detail of those insurance coverages, if any, that may be required pursuant to any Financing Agreement that are provided by a Corporate Insurance Policy, together with the applicable limits, deductibles and scope of coverage thereof.

6.32 No Negotiation. Except as permitted by Section 6.3, until such time, if any, as this Agreement is terminated pursuant to Section 9.1 or is partially terminated with respect to any particular Project pursuant to Section 9.3 (but then only with respect to any such particular Project), subject to fiduciary duties and prior notice to the Purchaser of the Sellers' intent to rely thereupon, if any, of directors under Applicable Law, the Sellers will not directly or indirectly solicit any inquiries or proposals from or negotiate with, or provide confidential information to, any Person (other than Purchaser) relating to any transaction or potential transaction involving the sale of any Project, any Acquired Company or any of the Shares or Owner Notes, or any merger, consolidation, business combination, or similar transaction related thereto.

6.33 Financing Cooperation.

(a) Subject to Section 6.1 and 6.26(a) and without limiting the generality of the foregoing, and subject to Seller's obligations in Section 6.1 and 6.26(a), between the Effective Date and the Closing Date, the Sellers will use Commercially Reasonable Efforts to cooperate with the Purchaser in connection with the preparation of any information memorandum, prospectus or similar investment circular for the purpose of or in connection with any post-Closing financing or refinancing of any indebtedness assumed or incurred in connection with the Contemplated Transactions (each, an

"Investment Circular") by providing the Purchaser with historical financial data and historical operating data that is reasonably requested by the Purchaser related to the Acquired Companies, except the provision of any such historical operating data shall be subject to applicable confidentiality or non-disclosure agreements in favor of third parties, if any.

(b) Subject to the procedures for indemnity set forth in Section 11.4, the Purchaser Parties will indemnify and hold the Sellers and their Affiliates harmless against any Losses to which the Sellers and their Affiliates may become subject insofar as such Losses arise out of or are based upon (i) an untrue statement or alleged untrue statement of material fact in the IPR Shareholder Circular or any Investment Circular, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, such untrue statement or alleged untrue statement or omission or alleged omission was not made in reliance upon and in conformity with written information furnished to the IPR by the Sellers expressly for use therein and (ii) any offering of securities, financing activities, solicitations (including solicitations of votes or proxies in connection with the IPR Shareholders Meeting) relating in any way to the IPR Shareholders Circular or any Investment Circular.

6.34 Certain Environmental Matters.

(a) Remediation Measures. In the event that EME becomes obligated to indemnify the Purchaser Indemnified Parties under the provisions of Section 11.3(a)(iii) for Remediation Measures in respect of Existing Soils Contamination, then the following provisions shall apply.

(i) If Remediation Measures are required by a Governmental Authority, then EME shall be deemed to have discharged such undertaking and its obligations with respect thereto whenever it has paid the cost of such Remediation Measures and it or the Purchaser has either received written notice from the pertinent Governmental Authority or Authorities that no further material Remediation Measures are then required with respect to the Existing Soils Contamination in question or, if such Governmental Authority or Authorities have not responded within a reasonable time to the request for such written notice, whenever the Purchaser or the applicable Purchaser Designee reasonably and in good faith determines that no further Remediation Measures are then required.

(ii) Whenever EME is obligated to indemnify the Purchaser Indemnified Parties in respect of Remediation Measures, EME may elect either to reimburse the Purchaser for the cost thereof or to assume and control the performance of such Remediation Measures in accordance with the provisions hereof. If EME elects to reimburse the Purchaser for the cost thereof, then (A) work in connection with such Remediation Measures shall be performed in a reasonably efficient and economical manner designed to mitigate EME's cost consistent with achievement of the Remediation Measures that are required, and (B) the provisions of Section 6.34(a)(iii), and Sections 6.34(a)(iv)(A), (B), (D) and (G) shall apply mutatis mutandis as though EME were the Purchaser therein and the Purchaser were EME.

(iii) In the event that EME elects to assume and control the performance of Remediation Measures pursuant to its indemnity obligations hereunder, then prior to commencing such Remediation Measures after the Closing or presenting after the Closing any plan for such Remediation Measures to any Governmental Authority having jurisdiction over such Remediation Measures or to any Person making an Environmental Claim for which EME is responsible for indemnity hereunder, EME shall meet and consult with Purchaser in good faith concerning such Remediation Measures or plan, as the case may be and use Commercially Reasonable Efforts to agree the scope of such Remediation Measures.

(iv) In connection with the performance of any Remediation Measures by EME pursuant to its indemnity obligations hereunder, EME shall:

(A) Provide the Purchaser with reasonable notice of any meetings with any such Governmental Authority or any such other Person to afford Purchaser or its representatives the right to participate in such meetings;

(B) Provide the Purchaser with a reasonable opportunity to preview and comment upon any submissions EME plans to deliver or submit to any such Governmental Authority or any such other Person;

(C) Meet and consult with the Purchaser in good faith over the time, manner and conditions for the completion of the Remediation Measures, so as to (and EME shall) avoid, to the extent reasonably practicable, material interference with business conducted or planned to be conducted at the site in question;

(D) Except to the extent that exigencies require shorter or no notice, provide the Purchaser with five (5) Business Days' prior notice (which may be oral) of material actions to be taken at the site in question in connection with Remediation Measures undertaken by EME and shall in any event, whether or not exigencies require shorter notice, permit the Purchaser the opportunity to have its representatives present to observe such Remediation Measures;

(E) After completion of any remediation project, make all reasonable efforts to restore the surface of the site involved to a condition substantially similar to its condition prior to the performance of the Remediation Measures, subject to any intervening changes in surface conditions not caused by such Remediation Measures;

(F) In connection with carrying out such Remediation Measures, comply with Applicable Law; and

(G) Permit the Purchaser to have one or more representatives present to observe physical work conducted at the Project in the course of carrying out such Remediation Measures, and provide Purchaser with reasonable access to and copies of records and physical samples concerning the performance of such physical work.

(v) In connection with the performance of any Remediation Measures by EME pursuant to its indemnity obligations hereunder, Purchaser agrees as follows:

(A) EME and its representatives and agents will have reasonable access to enter upon the real property at the site in question, to use all facilities or equipment located thereon (at EME's sole cost and risk, and subject to its availability after accounting for Purchaser's reasonable, good faith needs and subject to prior consultation with the Purchaser) and install equipment insofar as is necessary to allow for performance of the Remediation Measures, and to carry out its rights and obligations under this Section 6.34, except in case of emergency, and it will not relocate, disturb or interfere with such equipment or the performance of such Remediation Measures in compliance with the provisions of this Section 6.34;

(B) It will provide EME and its representatives and agents with reasonable access to environmental and other relevant records (other than those which are privileged) respecting the site as reasonably necessary for the purpose of carrying out such Remediation Measures and will provide EME with copies of all material correspondence and communications with Governmental Authorities about Existing Soils Contamination and Remediation Measures or otherwise pertaining to EME's Pre-Closing Environmental Liabilities;

(C) It will not submit, or cause to be submitted, to any Governmental Authority any information or comments concerning any Existing Soils Contamination or Remediation Measures undertaken by EME except for information routinely submitted to Governmental Authorities or as may be otherwise required by Law or in emergency; and

(D) Except as required by Law or in emergency, it will make Commercially Reasonable Efforts to avoid taking any action, and will take reasonable steps to cause others to avoid taking any action, that will increase or accelerate any of EME's Pre-Closing Environmental Liabilities hereunder including with respect to Remediation Measures.

(b) Site Tests. For a period of up to one hundred twenty (120) days after the Closing, Purchaser will exercise Commercially Reasonable Efforts to permit EME and its agents, representatives and contractors, if EME shall so elect, and subject to such reasonable and customary conditions that Purchaser may impose, to enter upon any and all of the real property included in the Projects for the purposes of making tests, taking samples and soil borings, or conducting groundwater studies and such other reasonable investigations in order to determine if there is any Existing Soils Contamination. All such activity and testing shall be at EME's sole cost. For the purposes of this Agreement, the results of such tests shall not be determinative.

6.35 Special Purpose Accounts. EME shall use its Commercially Reasonable Efforts to prepare, as soon as reasonably practicable following the Effective Date, audited accounts (the "Special Purpose Accounts") in accordance with US GAAP for the three (3) years ended December 31, 2003, as EME and Purchaser shall mutually agree, which Special Purpose Accounts shall represent adjustments to the historical results of operations and financial position of MEC BV and its Subsidiaries to reflect only the historical results of operations and financial position of the Acquired Companies. For the avoidance of doubt, EME will use its Commercially Reasonable Efforts to prepare the Special Purpose Accounts based on (i) the audited consolidated balance sheets of MEC BV as of the last day of each of the two (2) financial years ended on December 31, 2003 and (ii) the audited consolidated statements of income, cash flows and stockholders' equity of MEC BV for each of the three (3) financial years ended on December 31, 2003 (together the "Base Financial Data"). The Base Financial Data will reflect the relevant adjustments, modifications, procedures, assumptions and other matters relating thereto as EME and Purchaser may mutually agree such that the Special Purpose Accounts include the Acquired Companies and the Owner Notes and include or exclude, as the case may be, all other matters as required relevant to the Contemplated Transaction. EME shall use its Commercially Reasonable Efforts to provide information and assistance to the Purchaser, as the Purchaser shall reasonably require, in connection with the translation of the US GAAP accounts into UK GAAP. EME shall promptly provide to the Purchaser such quarterly statements for MEC BV and its Subsidiaries as it regularly prepared or prepares and received or receives for periods from January 1, 2003.

ARTICLE VII.
TAX MATTERS

7.1 Responsibility for Filing Tax Returns.

(a) EME shall prepare and file, or shall cause to be prepared and filed, all Tax Returns in respect of the Controlled Acquired Companies that (i) are required to be filed on or before the Closing Date or (ii) are required to be filed after the Closing Date and (A) are Consolidated Tax Returns of EME or its Affiliates (but excluding, for the avoidance of doubt, any Income Tax Return of a consolidated or multiple entry consolidated group for Australian Tax purposes for periods after the Closing Date), or (B) are with respect to Income Taxes and are required to be filed on a separate Tax Return basis for any taxable period ending on or before the Closing Date. Any such Tax Returns that include taxable periods ending on or before the Closing Date (including any associated claims, elections or other notices or filings) shall be on a basis consistent with the last filed such Tax Return, except as otherwise

required by Law; provided, any new claims, elections or other notices or filings made available as a result of a change in Law may be made so long as they do not have the effect of increasing a Controlled Acquired Company's liability for Taxes in a post-Closing period. EME shall provide a copy of any Tax Return described in clause (ii)(B) of the first sentence of this Section 7.1(a), and any Income Tax Return of a consolidated or multiple entry consolidated group for Australian Tax purposes that is to be filed by EME pursuant to the first sentence of this Section 7.1(a) after the date hereof, to the Purchaser Parties at least twenty (20) Business Days in advance of the due date for filing such return, and the Purchaser Parties shall be entitled to make comments regarding such return which EME is not required to adopt. If EME determines that any of the Controlled Acquired Companies is entitled to file or make a formal or informal claim for refund or file an amended Tax Return providing for a refund with respect to a period for which it is obligated to prepare or cause to be prepared the original such Tax Return pursuant to this Section 7.1(a), EME shall be entitled to file or make such claim or amended Tax Return on behalf of such Controlled Acquired Company and will be entitled to control and make all decisions and take all actions in its sole discretion in connection with the prosecution of such refund claims; provided, however, that EME shall inform the Purchaser Parties at least twenty (20) Business Days before filing any such refund claim or amended Tax Return and thereafter shall promptly inform the Purchaser Parties of developments relating to such claim or Tax Return; and provided further, that EME shall not take any action pursuant to this sentence that shall result in any material Tax liability for any Controlled Acquired Company for a period after the Closing Date.

(b) The Purchaser Parties shall prepare or cause to be prepared and shall file or cause to be filed all other Tax Returns in respect of the Controlled Acquired Companies required to be filed after the Closing Date. Any such Tax Returns that include taxable periods ending on or before the Closing Date shall be on a basis consistent with the last such Tax Return, except as otherwise required by Law, provided any new claims, elections or other notices or filings made available as a result of a change in Law may be made so long as they do not have the effect of increasing a Controlled Acquired Company's liability for Taxes in a Pre-Closing Period. With respect to (i) any Tax Return required to be filed by Purchaser for a taxable period that includes (but does not end on) the Closing Date (a "Straddle Period") and (ii) any Tax Return for non-Income Taxes to be filed by the Purchaser for a taxable period ending on or before the Closing Date, the Purchaser shall deliver to EME, at least 30 Business Days prior to the filing of such Tax Return, a detailed schedule setting forth the amount of Tax for which the Purchaser Indemnified Parties are entitled to be indemnified pursuant to Section 11.5 and a copy of such Tax Return. EME shall have the right to review such Tax Return and schedule prior to the filing of such Tax Return. EME and Purchaser agree to consult and resolve in good faith any issue arising as a result of EME's review of such Tax Return and schedule and mutually to consent to the filing of such Tax Return as promptly as possible. Neither the Purchaser nor any of its Affiliates shall file any amended Tax Returns for any taxable periods for or in respect of the Controlled Acquired Companies with respect to which the Purchaser is not obligated to prepare or cause to be prepared the original such Tax Returns pursuant to this Section 7.1(b), without the prior written consent of EME, except if such Tax Returns are required under Applicable Law or as a result of the final determination (or settlement to which EME has consented, such consent not to be unreasonably withheld or delayed) of an audit by a taxing authority or similar proceeding.

(c) Notwithstanding any provision of this Agreement to the contrary, the party that is legally required to file a Tax Return shall be responsible for the actual filing of such Tax Return.

7.2 Section 338 Election.

(a) No Purchaser Party or any of their respective Affiliates (including the Acquired Companies), shall make any election under Section 338 of the Code with respect to the Contemplated Transactions unless EME has been notified of the Purchaser's desire to do so, and EME in its sole discretion

consents in writing, at least thirty (30) days prior to the Closing Date, that such election will be made. If EME so consents, the provisions of Schedule 7.2 shall govern such election.

(b) Notwithstanding Section 7.2(a), the Purchaser shall, or shall cause the applicable Purchaser Designee to, make such elections under Section 338 of the Code as may be required by EME, provided such election is permitted under the Code and would not have a prejudicial effect on the Tax position of a Purchaser Party or an Affiliate of a Purchaser Party (including, after Closing, the Acquired Companies) at any time on or after the Closing Date, and the provisions of Schedule 7.2 shall govern such election.

7.3 Internal Restructurings. EME shall have the right in its sole discretion to cause elections pursuant to U.S. Treasury Regulations section 301.7701-3 to be filed, effective from any dates on or prior to the Closing Date, for any of the Acquired Companies that are not United States entities to be treated as branches or partnerships for U.S. federal Income Tax purposes.

7.4 Payment of Taxes.

(a) EME shall pay or cause to be paid on or before the due date therefor (i) all Taxes due with respect to Tax Returns which EME is obligated to prepare and file or cause to be prepared and filed pursuant to Section 7.1(a); (ii) all Taxes due with respect to Tax Returns for Straddle Periods for which the Purchaser Indemnified Parties are entitled to be indemnified pursuant to Section 11.5; (iii) all non-Income Taxes with respect to Tax Returns for non-Income Taxes to be filed by Purchaser for a taxable period ending on or before the Closing Date or a Straddle Period for which the Purchaser Indemnified Parties are entitled to be indemnified pursuant to Section 11.5; and (iv) all Taxes described in Section 11.5(a)(v).

(b) The Purchaser shall pay or cause to be paid on or before the due date therefor (i) all Taxes due with respect to Tax Returns which the Purchaser is obligated to prepare and file or cause to be prepared and filed pursuant to Section 7.1(b) other than Taxes which EME shall pay or cause to be paid in accordance with Section 7.4(a); and (ii) all Taxes owed by the Controlled Acquired Companies other than Taxes which EME shall pay or cause to be paid in accordance with the preceding sentence.

7.5 Refunds and Tax Benefits.

(a) Any Tax refunds (including the tax refunds listed on Schedule 7.5(a) and also including for the avoidance of doubt any interest component of such refunds) that are received by any Purchaser Party or any of its Affiliates, any applicable Purchaser Designee or any Controlled Acquired Company, and any amounts credited against Tax to which any Purchaser Party or any of its Affiliates, any applicable Purchaser Designee or any such Controlled Acquired Company have become entitled, that relate to taxable periods ending on or before the Closing Date and the portion of any Straddle Period ending on the Closing Date (net of any Taxes resulting from the receipt of such refund or credit) shall be for the account of EME, except to the extent that any indemnity payment under Section 11.5(a) is reduced on account of such refund or credit, and the Purchaser shall, or shall cause the applicable entity that received or is entitled to such Tax refund or credit to, pay over to EME an amount equal to any such refund or an amount equal to any such credit (net of any Taxes resulting from the receipt of such refund or credit) to which EME is entitled within fifteen (15) days after receipt of or entitlement thereto. The preceding sentence shall not apply to (i) the CBK VAT Credits, (ii) any refunds or credits resulting from the use in a post-Closing period of Tax losses that arose in a Pre-Closing Period and are properly carried forward into a post-Closing period, nor (iii) any refunds or credits resulting from the use in a Pre-Closing Period of Australian Tax losses described in Section 4.13(f) against taxable gain or income resulting from a transaction occurring outside the Ordinary Course of Business. For purposes of clause (iii) of the preceding sentence, any restructuring or reorganization of a relevant Controlled Acquired Company with effect during or after 2004 shall be considered outside the Ordinary Course of Business, but all restructurings or reorganizations arising from Project Partial Termination Events in

respect of the Project-Specific Acquired Companies listed opposite the Projects known as "Valley Power" or "Kwinana" shall be deemed to be in the Ordinary Course of Business (but only to the extent that the aggregate income or gains resulting from such restructurings or reorganizations does not exceed AU$20,000,000). To the extent that a claim for refund or a proceeding results in a payment or credit against Tax by a Tax Authority to any Purchaser Party or any of its Affiliates, any applicable Purchaser Designee or any Controlled Acquired Company of any amount accrued by the applicable Acquired Company as of the Closing Date (as evidenced by the customary accounting records for such Acquired Company), the Purchaser shall, or shall cause the applicable entity that received or is entitled to such Tax refund or credit to, pay such amount (net of any Taxes resulting from the receipt of such refund or credit) to EME within fifteen (15) days after receipt of or entitlement thereto, except to the extent that an indemnity payment under Section 11.5(a) is reduced on account of such refund or credit.

(b) The Purchaser and its Affiliates (including the applicable Purchaser Designees and the Controlled Acquired Companies) shall be entitled to any (i) refunds or credits on account of which an indemnity payment under Section 11.5(a) is reduced, (ii) refunds or credits of Taxes of the Controlled Acquired Companies that are attributable to any taxable period or portion thereof beginning after the Closing Date and (iii) refunds or credits for Taxes for which the EME Indemnified Parties are entitled to be indemnified pursuant to Section 11.5, in each case net of any Taxes resulting from the receipt of such refund or credit.

(c) The Purchaser shall cause the Controlled Acquired Companies to elect, when permitted by Law, to carry forward any net operating loss or other item arising after the Closing Date that could, in the absence of such an election, be carried back to a taxable period of such Controlled Acquired Companies ending on or before the Closing Date in which such companies were included in a Consolidated Tax Return of EME or its Affiliates. The Purchaser, on its own behalf and on behalf of its Affiliates (including the Purchaser Designees), hereby waives (to the extent permitted under Applicable Law) any right to use or apply any net operating loss or other item of the Controlled Acquired Companies for any Tax year ending on any date following the Closing Date to any period of such Controlled Acquired Companies ending on or before the Closing Date. If any net operating loss or other item shall be carried back to any such period (except where such carry-back is required under Applicable Law or as the result of a final determination of a Tax audit or similar proceeding to which EME consents), Purchaser shall indemnify EME and its Affiliates (other than the Acquired Companies) for all reasonable costs and expenses incurred by EME or any of its Affiliates in filing such claims or in connection with any audit of such claims.

(d) No Controlled Acquired Company shall, and EME shall cause the Controlled Acquired Companies not to, use in a Pre-Closing Period any Australian Tax losses described in Section 4.13(f) against taxable gain or income resulting from a transaction occurring outside the Ordinary Course of Business (it being understood that any restructuring or reorganization of a relevant Controlled Acquired Company with effect during or after 2004 shall be considered outside the Ordinary Course of Business, but all restructurings or reorganizations arising from Project Partial Termination Events in respect of the Project-Specific Acquired Companies listed opposite the Projects known as "Valley Power" or "Kwinana" shall be deemed to be in the Ordinary Course of Business (but only to the extent that the aggregate income or gains resulting from such restructurings or reorganizations does not exceed AU$20,000,000)).

7.6 Cooperation on Tax Matters.

(a) The Parties shall cooperate fully, as and to the extent reasonably requested by EME or the Purchaser, as the case may be, in connection with the filing of Tax Returns pursuant to this Article VII and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include (i) if required by Applicable Laws, the Purchaser and its Affiliates to execute, file or take any other action with respect to any Tax Return or other documentation described in Section 7.1(a) and (ii) the

retention and (upon either EME's or the Purchaser's request) the provision of records and information possessed by the relevant party that are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Purchaser and its Affiliates (including the applicable Purchaser Designees and, after the Closing, the Controlled Acquired Companies) and EME and its Affiliates agree (A) to retain all books and records possessed by the relevant party with respect to Tax matters pertinent to the Controlled Acquired Companies relating to any taxable period beginning before the Closing Date until the expiration of the applicable statute or other rule of limitations (and, to the extent notified by the Purchaser or EME, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any Tax Authority, and (B) to give the other Parties reasonable written notice prior to transferring, destroying or discarding any such books and records and, if EME or the Purchaser, as the case may be, so requests the Purchaser and its Affiliates (including the applicable Purchaser Designees and, after the Closing, the Controlled Acquired Companies) and EME and its Affiliates, as the case may be, shall allow the other Parties to take possession of such books and records.

(b) The Purchaser and its Affiliates (including the applicable Purchaser Designees and, after the Closing, the Controlled Acquired Companies) and EME and its Affiliates shall (i) consult with each other prior to taking any position or settling any claim with respect to Taxes that could reasonably be expected to have a Material Adverse Effect on EME, any Seller or any of their respective Affiliates or the Purchaser or any of its Affiliates, as the case may be, and (ii) not take any action with respect to Taxes that would legally bind the other Parties or any of their respective Affiliates without the prior written consent of EME or the Purchaser, as the case may be. The Purchaser and its Affiliates (including the applicable Purchaser Designees and, after the Closing, the Controlled Acquired Companies) and EME and its Affiliates further agree, upon request, to use their Commercially Reasonable Efforts to obtain any certificate or other document from any Tax Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including with respect to the Contemplated Transactions).

(c) The Purchaser and its Affiliates (including the applicable Purchaser Designees and, after the Closing, the Controlled Acquired Companies) shall promptly notify EME in writing: (x) of any audit instituted for any period for which the Purchaser Indemnified Parties are entitled to be indemnified pursuant to Section 11.5, and shall provide periodic status updates of potential Tax Claims for such period, and (y) upon the termination by a Controlled Acquired Company of the employment of any of the individuals in the positions listed on Schedule 7.6(c). The Purchaser shall, within the earlier to occur of one hundred and twenty (120) days after EME's year-end and one hundred and twenty (120) days after the Closing Date, prepare or cause the Controlled Acquired Companies to prepare, in a manner consistent with such Controlled Acquired Companies' past practice, the Tax workpaper preparation package or packages necessary to enable EME to prepare Tax Returns that EME is obligated to prepare or cause to be prepared.

7.7 Tax-Sharing Agreements and Other Elections.

(a) On the Closing Date, except as otherwise set forth on Schedule 7.7(a), all Tax-sharing agreements or similar agreements between (i) the Acquired Companies, on the one hand and (ii) EME or its Affiliates (other than the Acquired Companies), on the other hand, shall be terminated effective as of the close of the Closing Date and have no further effect for any taxable year or period (whether a past, present or future year or period), and no additional payments shall be made thereunder after the Closing Date with respect to any period.

(b) Notwithstanding anything in Section 7.7(a) or elsewhere in this Agreement to the contrary, for any taxable period ending on or before the Closing Date, EME and the Purchaser shall agree:

(d) (i) EME agrees to procure that one or more elections are entered into by one or more members of the EME UK Group under section 179A TCGA in order to ensure that the total amount of any liability that would otherwise have accrued to any Acquired Company under section 179 TCGA as a result of the sale of the Acquired Company pursuant to the Agreement is treated as accruing to a member of the EME UK Group or that parts of that liability equaling in aggregate the total amount of that liability are treated as accruing to one or more members of the EME UK group.

(ii) EME agrees to procure that one or more elections are entered into by EME or one or more members of the EME UK Group under paragraph 66 of Schedule 29 of the Finance ▇▇▇ ▇▇▇▇ in order to ensure that the total amount of any liability that would otherwise have accrued to any Acquired Company under paragraph 58 or 60 of Schedule 29 of the Finance ▇▇▇ ▇▇▇▇ as a result of the sale of the Acquired Company pursuant to the Agreement is treated as accruing to a member of the EME UK Group or that parts of that liability equaling in aggregate the total amount of that liability are treated as accruing to one or more members of the EME UK Group.

(iii) EME will supply the elections mentioned in Section 7.7(d)(i) and Section 7.7(d)(ii) signed by the requisite members of the EME UK Group to the Purchaser on Closing and will provide such assistance as the Purchaser may reasonably require in order to get each election accepted by the U.K. Inland Revenue.

(a) Representations and Warranties of the Seller Parties. Without limiting the Sellers' obligations under Section 6.20, each of the representations and warranties made by the Seller Parties in this Agreement or any Related Agreement shall be true and correct (determined without regard to any qualification therein as to materiality or Material Adverse Effect) on and as of the Effective Date (unless the inaccuracy or inaccuracies as of the Effective Date which would otherwise result in a failure of this condition have been cured on or before the Closing) and as of the Closing Date, except for those representations and warranties of EME that speak only as of a certain date other than the Effective Date, which representations and warranties shall have been true and correct as of such date; except in each case, where the failure of such representations and warranties to be true and correct would not have a Material Adverse Effect.

(b) Performance of Obligations of the Sellers. The Sellers shall have performed in all material respects the material obligations required to be performed by them under this Agreement at or prior to the Closing Date.

(c) Closing Deliveries. Each of the Purchaser Parties shall have been furnished with the documents referred to in Section 3.4 and any applicable Foreign Implementing Agreements.

The Third Party Conditions of the Purchaser Parties set forth on Schedule 8.2(d) shall have been satisfied and shall be in effect in relation to each Project, save to the extent that any of those conditions relate to a Project in respect of which a Project Partial Termination Event has occurred. For the avoidance of doubt, subject to Section 8.1(e), the failure of a Third Party Condition in this Section 8.2(d) or Section 8.3(d) with respect to a Project, unless otherwise waived, will result in a Project Partial Termination Event with respect to such Project only.

(e) No Material Adverse Effect. Since the Effective Date, no fact or condition shall have occurred which has resulted in a Material Adverse Effect.

(f) Accountants Report. If, and only to the extent that, the Sellers have provided the Purchaser with audited Financial Statements of MEC BV in connection with the IPR Shareholder Circular, the Purchaser shall have received a customary bring-down comfort letter in connection therewith.

(h) Defaults under Financing Agreements. There shall be no event of default under a Financing Agreement related to a Minimum Threshold Project or an event that with notice or passage of time would become an event of default under such Financing Agreement, unless such event has been excused or waived (and if such waiver is temporary, on terms reasonably acceptable to the Purchaser); provided that if the condition set forth herein is not met as of the Outside Date, and EME reasonably believes that an extension of the Outside Date could result in such condition being satisfied, then EME shall have the right to extend the Outside Date (but not beyond the last date specified in the definition of "Outside Date" in Section 10.1) upon written notice to the Purchaser; and provided, further, that the Purchaser shall use its Commercially Reasonable Efforts to assist the Sellers in their removal of any impediments to the satisfaction or waiver of this condition. For purposes of this Section 8.2(h), "default" means: (a) an event of default by reason of nonpayment, insolvency or breach of financial covenant, (b) any other event of default that a purchaser in the position of the Purchaser would reasonably conclude was likely to result in an acceleration of indebtedness, or (c) any other event that a purchaser in the position of the Purchaser would reasonably conclude was likely to result in the imposition of distribution lock-ups or restrictions as described in Section 4.23(b), under the Financing Agreement in question, but for purposes of this Section 8.2(h), "default" does not include events and events of default set forth on Section 4.11(c) of the EME Disclosure Schedule at the Effective Date.

(i) Minimum Distributions. The aggregate amount of all Relevant Distributions made, directly or indirectly, during the period commencing on October 1, 2003 and ending on July 31, 2004 shall be an amount equal to at least $168,000,000; provided, however, if the Outside Date of this Agreement is extended, then the condition contained in this Section 8.2(i) shall only be satisfied by Sellers providing the Purchaser with evidence (in form and substance satisfactory to the Purchaser acting reasonably) that the aggregate amount of all Relevant Distributions made, directly or indirectly, during the twelve (12) month period ending on the last day of the calendar month preceding the calendar month in which the Closing is to occur is not less than ninety percent (90%) of the aggregate amount of all Estimated Project Distributions for such period, excluding any Relevant Distributions attributable to any Projects in respect of which there has occurred a Project Partial Termination Event. With respect to the proviso of the foregoing sentence, actual Distributions included in such period for purposes of such proviso shall be deemed to include such Estimated Project Distributions for the months in question that EME demonstrates to the Purchaser's reasonable satisfaction have been temporarily delayed and will be paid no later than January 31, 2005, if and only to the extent such Distributions are actually received by such date.

(j) Netherlands Charter Amendments. The articles of association of the entities listed on Schedule 8.2(j) shall have been amended effective as of January 1, 2003, so as not to include the corresponding sections set forth opposite such entity's name on Schedule 8.2(j).

Each of the representations and warranties of the Purchaser Parties contained herein shall be true and correct in all material respects (except in the case of any such representation or warranty containing a materiality qualification, in which case such representation or warranty shall be true and correct in all respects) on and as of the Effective Date (unless the inaccuracy or inaccuracies as of the Effective Date which would otherwise result in a failure of this condition have been cured as of the Closing) and as of the Closing Date and, for this purpose, where there is an express or implied reference in Article V to the "Effective Date", that reference is to be construed as a reference to the "Closing Date" except for those representations and warranties of the Purchaser Parties that speak only as of a certain date other than the Effective Date, which representations and warranties shall have been true and correct in all material respects as of such date (except in the case of any such representation or warranty containing a materiality qualification, in which case such representation or warranty shall have been true and correct in all respects, taking into account such qualification).

(b) Performance of Obligations of Purchaser Parties. The Purchaser Parties shall have performed in all material respects the material obligations required to be performed by them under this Agreement at or prior to the Closing Date.

(c) Closing Deliveries. EME shall have been furnished with the documents referred to in Section 3.5 and any applicable Foreign Implementing Agreements.

(d) Third Party Seller Conditions. The Third Party Conditions of the Sellers set forth in Schedule 8.3(d) shall have been satisfied and shall be in effect, save to the extent any of those conditions relate to a Project in respect of which a Project Partial Termination Event has occurred.

8.4 Conditions Precedent to Obligations of Each Party Relating to the Second Closing. Without limiting Sections 3.2 or 9.3, the respective obligations of each of the Sellers and the Purchaser Parties to consummate the transactions subject to the Second Closing shall be subject only to the condition that the First Closing shall have occurred.

(e) By EME by notice in writing to the other Parties, so long as neither it nor any other Seller is then in breach of its representations, warranties or covenants in this Agreement in any material respect, upon a material breach or default by any Purchaser Party or Purchaser Designee (individually or in the aggregate) under this Agreement which is not cured by the earlier of the Closing Date for such Project or the date that is thirty (30) days after receipt by Purchaser of written notice from EME specifying with particularity such breach or default; provided, however, that EME shall not be entitled to terminate this Agreement pursuant to this Section 9.1(e) so long as each of the applicable Purchaser Parties or Purchaser Designees, as the case may be, is using its Commercially Reasonable Efforts to cure such material breach or default and such breach or default is capable of cure on or before the Outside Date;

No termination of this Agreement pursuant to Section 9.1(c), Section 9.1(d), Section 9.1(e), Section 9.1(f) and Section 9.1(g) shall be effective until a termination notice is delivered to the non-terminating Party specifying any and all corresponding provisions of this Agreement underlying such termination. If validly terminated pursuant to Section 9.1, this Agreement shall become void and of no further force and effect without further liability to any Seller, Purchaser Party or any applicable Purchaser Designee or any of their respective Subsidiaries, Affiliates or Representatives, except that (i) termination shall not affect a Party's accrued rights and obligations under this Agreement as at the date of termination and (ii) the obligations of the Purchaser Parties and any applicable Purchaser Designee under the Confidentiality Agreements and the obligations of the Parties under Article XII of this Agreement shall remain in full force and effect; provided, however that nothing in this Section 9.2 shall be deemed to release any Party from liability for any willful breach of its obligations under this Agreement in any material respect.

9.3 Partial Termination.

(a) Project Partial Termination. Notwithstanding anything in Section 9.1 or Section 9.2 to the contrary, the respective obligations of the Sellers and the Purchaser Parties hereunder relating to any particular Project (i) if not terminated earlier, will be terminated automatically if any condition set out

in Section 8.1, Section 8.2(d) or Section 8.3(d) has not been satisfied or waived in relation to such a Project on the Closing Date; and (ii) may be terminated upon written notice delivered by EME to the Purchaser or the Purchaser to EME, as the case may be, if the terminating Party reasonably believes that, notwithstanding the use of Commercially Reasonable Efforts, it is or has become impossible to satisfy a condition set out in Section 8.1, Section 8.2(d) or Section 8.3(d) in relation to a specified Project, in each case with a corresponding reduction in the Aggregate Purchase Price determined in accordance with Section 2.4. A "Project Partial Termination Event" will be deemed to have occurred in respect of a Project if the obligations of the Sellers and the Purchaser Parties under this agreement relating to that Project are terminated by virtue of the operation of this Section 9.3.

(b) Effect of Project Partial Termination Event. If a Project Partial Termination Event occurs in relation to a Project then this Agreement shall become void and of no further force and effect with respect to such Project without liability to any Seller, Purchaser Party or any applicable Purchaser Designee or any of their respective Subsidiaries, Affiliates or Representatives, except that the obligations of the Purchaser Parties and any applicable Purchaser Designee under the Confidentiality Agreements and the obligations of the Parties with respect to such Project under this Section 9.3(b) and under Sections 1.5, 6.12 and Article XII of this Agreement shall remain in full force and effect; provided, however, that nothing in this Section 9.3(b) shall be deemed to release any Party from liability for any willful breach of its obligations under this Agreement in any material respect. No Project Partial Termination Event shall (i) affect any provision of this Agreement as it applies to the Shares, the Owner Notes or the EME Guarantees other than to the extent such Shares, Owner Notes and EME Guarantees relate exclusively to the Project to which such Project Partial Termination Event relates or (ii) terminate the respective obligations of the Sellers and the Purchaser Parties to consummate the Contemplated Transactions with respect to the Shares, the Owner Notes, the EME Guarantees or any Project other than a Project to which the Project Partial Termination Event relates. Notwithstanding the foregoing, in the event that a Project Partial Termination Event occurs with respect to a Project, the Sellers shall cause the Project and each Project-Specific Acquired Company, Owner Note and EME Guarantee specifically related thereto to be transferred or otherwise separated from MEC BV and its Subsidiaries without Liability (whether actual or contingent and including any Liability for Tax) on the part of any Acquired Company and in a manner which does not prevent or limit the ability of MEC BV or any of its Subsidiaries to pay dividends or otherwise distribute amounts to their respective shareholders.

(c) Cooperation. If any Project is subject to a Project Partial Termination Event, the Parties agree to work cooperatively in good faith to resolve any separation, transition and IT issues arising therefrom and shall commence the transition of IT systems for the Project in accordance with Section 6.25.

11.2 Exclusive Remedy. Absent intentional fraud, from and after the Closing, (a) the remedies contained in this Article XI shall be the sole and exclusive remedy of any Party or indemnitee hereunder for monetary recovery, including damages (whether based on contract, tort or any other theory) and, to the extent permitted by Law, each Party and indemnitee agrees not to make, and releases any right it may have to make, any other claim for monetary recovery under any Applicable Law, including any securities Law to the extent waivable, in connection with (i) any untruth or inaccuracy in any representation or breach of any warranty in this Agreement or any related certificates or other documents delivered pursuant to this Agreement, and (ii) any failure by a Party to perform or observe any term, provision, covenant, or agreement in this Agreement to be performed or observed by such Party, and (iii) any act or omission concerning any Share, Owner Note, Acquired Company or Project (or for any statement or representation about any of the foregoing), in each case except in accordance with the provisions of this Article XI, and (b) subject to the following sentence, indemnification with respect to Taxes shall be governed solely by Section 11.5. Subject to Section 11.6, and notwithstanding EME's acting as agent for other Sellers or any other provision herein, all claims by a Purchaser Indemnified Party under this Agreement shall be made against EME only, and no Purchaser Party, Purchaser Designee or other Purchaser Indemnified Party shall have the right to institute any Action or make any claim against any such other Sellers under this Agreement

11.3 Indemnification Coverage.

(a) Except with respect to Taxes, indemnification for which is dealt with exclusively in Section 11.5, EME shall indemnify and defend, save and hold the Purchaser Indemnified Parties harmless from and against any and all claims, demands, suits, losses (including loss of value), liabilities, damages, costs and expenses, including reasonable attorneys' fees and costs of investigation, litigation, settlement and judgment (collectively, "Losses") which they sustain or suffer or to which they become subject as a result of:

(i) any inaccuracy in or any breach, as of the Effective Date or the Closing Date, of any representation or warranty of any of the Seller Parties contained in this Agreement, any Related Agreement or any certificates or other documents delivered pursuant to this Agreement (other than a breach of the representation or warranty set forth in Section 4.16 which is indemnified under clause (iii) below) or any Related Agreement; provided, however, that if any such representation or warranty is qualified in any respect by reference to materiality or Material Adverse Effect, for purposes of this clause (i) such qualification shall in all respects be disregarded; provided, further, that if the occurrence of an event disclosed in an update pursuant to Section 6.20 is expressly permitted by Section 6.3, or the Purchaser's condition in Section 8.2(e) was satisfied by waiver, then disclosure of such event shall not be disregarded for purposes of determining whether there was any inaccuracy in, or any breach of, any representation or warranty as of the Closing Date.

(ii) any failure to perform or observe any term, provision, covenant or agreement in this Agreement or any Related Agreements to be performed or observed by the Seller Parties or any of them;

(iii) all Pre-Closing Environmental Liabilities, provided that any and all claims under this provision must be asserted prior to the fourth anniversary of the Closing Date;

(v) any failure by an Acquired Company to obtain from National Power Corporation the Certificate of Completion of Kalayaan II Unit 2 under the BROT Agreement, dated November 6, 1998, stating a date of completion for the Project known as "CBK" of January 22, 2004 or earlier; and

(vi) the ownership or operation of the Excluded Items (including any obligation that may be imposed on the Purchaser or any of its Affiliates under the New Zealand Takeovers Code or otherwise as a result of the Contact Sale Transaction) and any Project or Project-Specific Acquired Company (and any related business) that becomes separated from MEC BV and its Subsidiaries as a result of the exercise of a Preemptive Right or is otherwise not sold or transferred to the Purchaser and its Affiliates pursuant to this Agreement, as well as the ownership or operation prior to the Closing Date of any Acquired Holding Company of any such Project-Specific Acquired Company that is rendered inactive and has no direct or indirect ownership interest in an active Acquired Company as a result of such separation.

(b) Except with respect to Taxes, indemnification for which is dealt with exclusively in Section 11.5, in the case of clause (i) below only, the Purchaser Parties severally and, in the case of the remainder of this Section 11.3(b), the Purchaser, shall indemnify and defend, save and hold the Sellers and their respective Affiliates, successors and permitted assigns (collectively the "EME Indemnified Parties") harmless from and against any and all Losses which they sustain or suffer or to which they become subject as a result of:

(i) any inaccuracy in any representation by any Purchaser Party (or any Purchaser Designee) or the breach of any warranty by any Purchaser Party (or any Purchaser Designee) contained in this Agreement or any certificates or other documents delivered pursuant to this Agreement without regard to any of the qualifications as to materiality or Material Adverse Effect set forth herein or therein;

(ii) any failure to perform or observe any term, provision, covenant or agreement in this Agreement to be performed or observed by any Purchaser Party (or any Purchaser Designee); and

(iii) after the applicable Project Closing, any EME Guarantee or letter of credit in respect of which any of the EME Guarantee Parties or other pertinent EME Subsidiaries was not fully and unconditionally released as contemplated by Section 6.14, to the extent any such EME Guarantee or letter of credit relates to the Project-Specific Acquired Companies that were the subject of such Project Closing; and

(iv) Third Party Claims arising from the ownership or operation of the Acquired Companies and their respective businesses by the Purchaser after the Closing Date.

(i) The aggregate amount of Losses for which EME has liability under Section 11.3(a)(i) and Section 11.3(a)(iii) and for which the Purchaser Parties have liability under Section 11.3(b)(i) shall not, in either case, exceed a dollar amount equal to thirty percent (30%) of the sum of the unadjusted Project Purchase Prices of all Projects acquired by the Purchaser or Purchaser

Designees under this Agreement (the "Cap"); provided, however, that the Cap shall not be applicable to any untruth or inaccuracy in any representation or the breach of any warranty contained in Sections 4.1 or 5.1 (Organization and Good Standing), Section 4.2 (Authority and Enforceability), Section 4.5 (Ownership Interests) or Section 4.4(c) (Consents).

(ii) No indemnification for any Losses asserted against EME under Section 11.3(a)(i) or Section 11.3(a)(iii) or against any Purchaser Party under Section 11.3(b)(i) shall be required (x) unless and until the cumulative aggregate amount of all such Losses exceeds a dollar amount equal to $20,000,000 (the "Deductible Amount"), at which point EME or the Purchaser Parties, as the case may be, shall be obligated to indemnify the Indemnified Party as to the amount of such Losses in excess of the Deductible Amount only, up to the Cap set forth in Section 11.3(c)(i); provided, however, that individual claims of $50,000 or less (or its equivalent in foreign currency) (the "Individual Claims Limit") shall not be aggregated for purposes of calculating either the Deductible Amount or the excess of Losses over the Deductible Amount; provided, further, that nothing in this Section 11.3(c)(ii) shall apply to indemnification for Losses asserted against an Indemnifying Party arising from any untruth or inaccuracy in any representation or breach of any warranty contained in Sections 4.1 or 5.1 (Organization and Good Standing), Section 4.2 (Authority and Enforceability), Section 4.5 (Ownership Interests), Section 4.10 (Title to Properties) or Section 4.13 (Taxes) or Section 4.18 (Sufficient Assets). For the avoidance of doubt, any Losses incurred in excess of the Project Deductible Amount shall, prior to the exhaustion of the Deductible Amount, be applied towards such Deductible Amount.

(iii) Subject in every case to the Cap set forth in Section 11.3(c)(i) above, the aggregate amount of Losses for which EME has liability under Section 11.3(a)(iii) with respect to any Project shall not, in any case, exceed a dollar amount equal to one hundred percent (100%) of the unadjusted Project Purchase Price for such Project (the "Environmental Sublimit"). No indemnification for any Losses asserted against EME under Section 11.3(a)(iii) with respect to any Project shall be required unless and until (i) the amount of all such Losses with respect to such Project exceeds a dollar amount equal to $5,000,000 (the "Project Deductible Amount") and (ii) the Deductible Amount set forth in Section 11.3(c)(ii) has been exhausted, at which point EME shall be obligated to indemnify the Indemnified Party as to the amount of any such Losses in excess of the Project Deductible Amount and the Deductible Amount only up to the Environmental Sublimit for such Project, provided, that individual Losses under Section 11.3(a)(iii) which do not exceed the Individual Claims Limit shall not be aggregated for purposes of calculating the Project Deductible Amount or the Deductible Amount or the excess of Losses over the Project Deductible Amount or the Deductible Amount.

(iv) The aggregate amount of Losses for which EME has liability under Section 11.3(a)(v) shall not exceed a dollar amount equal to $102,700,000.

(v) An Indemnified Party shall not be entitled under this Agreement to multiple recovery for the same Losses. Without limiting the foregoing, the amount of any Losses suffered by an Indemnified Party shall be reduced by any third-party insurance payments, or other payments from third parties, which such Indemnified Party receives in respect of or as a result of such Losses. If any Losses for which indemnification is provided and paid hereunder are subsequently reduced by any third-party insurance or other payments from third parties, the amount of the reduction shall be remitted to the applicable Indemnifying Party net of Tax and other costs of recovery.

(vi) No claim may be asserted nor may any Action be commenced for indemnity pursuant to Section 11.3(a)(i) under this Article XI, unless written notice of such claim or Action, describing in reasonable detail the known facts and circumstances with respect to the subject matter of such claim or Action, is provided to the applicable Indemnifying Party on or prior to the end of the Survival Period.

(vii) In no event shall any Indemnifying Party be liable to any Indemnified Party pursuant to this Article XI for any Losses in the nature of consequential damages, punitive damages, restitution, lost profits and damage to reputation, in each case except for indemnification for Third Party Claims.

(viii) In determining the amount of indemnification due under Sections 11.3 and 11.5, all payments shall be reduced by, or returned to the Indemnifying Party in, the amount of any Tax benefit actually realized by the Indemnified Party on account of the underlying claim promptly after the benefit is realized.

11.4 Procedures.

(a) Any party entitled to indemnification under this Article XI (each an "Indemnified Party") shall promptly upon its discovery of facts or circumstances giving rise to a claim for indemnification, including receipt by it of notice of any demand, assertion, claim or Action by any third party (such third party Actions being collectively referred to herein as "Third-Party Claims"), give notice thereof (the "Claim Notice") to the Person or Persons obligated to provide indemnification under this Article XI (each an "Indemnifying Party"). Failure to timely provide such notice will not affect any rights hereunder unless (and then only to the extent that) the Indemnifying Party is materially prejudiced thereby. In providing any Claim Notice to the Indemnifying Party in respect of any Third-Party Claim, the Indemnified Party shall provide the Indemnifying Party with a copy of such Third-Party Claim or other documents received and shall otherwise make available to the Indemnifying Party all relevant information material to the defense of such claim and within the Indemnified Party's possession.

(b) Within thirty (30) days after the date of the Claim Notice, the Indemnifying Party shall notify the Indemnified Party whether it acknowledges its obligation to indemnify in accordance with this Article XI without any reservation of rights or whether it intends to fulfill its indemnification obligation with a reservation of rights.

(i) If the Indemnifying Party acknowledges its obligation to indemnify without any reservation of rights, then the Indemnifying Party shall have the right, by notice given to the Indemnified Party within thirty (30) days after the date of the Claim Notice, to assume and control the defense of the Third-Party Claim that is the subject of such Claim Notice, including the employment of counsel selected by the Indemnifying Party after consultation with the Indemnified Party, and the Indemnifying Party shall pay all expenses of, and the Indemnified Party shall cooperate fully with the Indemnifying Party in connection with, the conduct of such defense. The Indemnified Party shall have the right to employ separate counsel in any such Action and to participate in (but not control) the defense of such Third-Party Claim, but the fees and expenses of such counsel shall be borne by the Indemnified Party unless the Indemnifying Party shall agree otherwise; provided, however, if the named parties to any such Third-Party Claim (including any impleaded parties) include both the Indemnified Party and the Indemnifying Party, the Indemnifying Party requires that the same counsel represent both the Indemnified Party and the Indemnifying Party, and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, then the Indemnified Party shall have the right to retain its own counsel at the cost and expense of the Indemnifying Party.

(ii) If the Indemnifying Party notifies the Indemnified Party that it intends to fulfill its indemnification obligation with a reservation of rights, or fails to make any notification required by this Section 11.4(b), then the Indemnified Party shall have the absolute right to control the defense of such Third-Party Claim, and, if and when it is finally determined that the Indemnified Party is entitled to indemnification from the Indemnifying Party hereunder, the fees and expenses of the Indemnified Party's counsel shall be borne by the Indemnifying Party, provided that the Indemnifying Party shall be entitled, at its expense, to participate in (but not control) such defense.

(c) Neither the Indemnifying Party nor the Indemnified Party shall have the right to settle or compromise any such Third-Party Claim without the consent of the other, which consent shall not be unreasonably withheld or delayed.

11.5 Tax Indemnification.

(a) EME Indemnification. EME shall indemnify, defend, save and hold the Purchaser Indemnified Parties harmless from and against (i) all liability for Taxes of and in respect of the Controlled Acquired Companies for any taxable period that ends on or before the Closing Date and the portion of any Straddle Period ending on such Closing Date ("Pre-Closing Period"), (ii) all liability (as a result of Treasury Regulation section 1.1502-6, any analogous provisions of foreign Laws or otherwise) for Taxes of EME or any other Person (other than the Acquired Companies) which is or has ever been affiliated with the Controlled Acquired Companies, or with whom the Controlled Acquired Companies otherwise join or have ever joined (or are or have ever been required to join) in filing any Consolidated Tax Return, prior to the Closing Date, (iii) all liability for any breach of the Sellers' representations and warranties contained in Section 4.13 in respect of a Pre-Closing Period subject, in relation to sub-sections (e) and (f) thereof, to Section 11.5(aa) (iv) all liability under any Tax sharing, allocation or indemnity agreement or arrangement to which an Acquired Company is or has been a party at any time prior to the Closing, (v) all Taxes resulting from restructurings or reorganizations undertaken by EME, any of its Affiliates or any Acquired Company on or prior to the Closing, including the Delayed Project Spin-Offs, the transactions described in Sections 1.3, 6.16, 6.17 and 6.21, any transfer of assets in the event of a Project Partial Termination Event and any Permitted Transfer, (vi) any liability to Tax of and in respect of a Pre-Closing Period of Ibérica, as parent company of EMESL, or of EMESL where such liability would not have arisen but for the disallowance for Tax purposes of EMESL's amortisation, deductions and expenses (interest and other funding costs) in relation to an inducement payment made by EMESL to its former parent company, (vii) all Liability for Taxes (whenever arising) which arises as a result of any breach by EME of the covenants contained in Article VII and (viii) all costs, losses or expenses (including without limitation reasonable attorneys' or accountants' fees) relating to Taxes or liabilities described in clause (i) to (v) of this Section 11.5 provided, however, that EME's indemnity obligation pursuant to this Section 11.5(a) shall be reduced by refunds of Taxes with respect to such periods received after the Closing Date by Purchaser or any of its Affiliates and not previously remitted to EME and for any estimated or prepaid Taxes made on or prior to the Closing Date for a post-Closing period. Notwithstanding the foregoing, EME shall not indemnify, defend or hold harmless the Purchaser Indemnified Parties from any liability for Taxes attributable to any Purchaser Tax Act. Where a liability under Section 11.5(a) arises in relation to a Non-Controlled Acquired Company, EME's indemnification obligations shall be satisfied by payment of an amount which in relation to such liability is in the same proportion as to the interest which EME holds directly or indirectly in the relevant Non-Controlled Acquired Company. The matters disclosed in the EME Disclosure Schedule shall not qualify the indemnification provided under this Section 11.5(a) except for clause (iii) with respect to the Project-Specific Acquired Companies listed opposite the Project known as "Paiton" on Schedule A-2.

(aa) Sections 4.13(e) and (f). If there is a breach of the representations and warranties in Section 4.13(e) other than Section 4.13(e)(vii) then EME's indemnification obligation shall be equal to the tax which the relevant Acquired Company has to pay (whether before or after Closing) and which it would not have had to pay had the representation or warranty been accurate. If there is a breach of the representations and warranties in Section 4.13(e)(vii), then EME's indemnification obligation shall be satisfied by payment of a sum equal to 50 percent multiplied by 50 percent of 85 percent of the value of the CBK VAT Credits. If there is a breach of the representations and warranties in Section 4.13(f), then EME's indemnification obligation shall be satisfied by payment of a sum equal to (i) $35,000,000 multiplied by (ii) the fraction calculated by dividing (x) the amount in Australian dollars

of the Tax losses in relation to the relevant Controlled Acquired Companies which prove not to be available by (y) AU$380,000,000.

(b) Purchaser Indemnification. The Purchaser (including the applicable Purchaser Designees and, after the Closing, the Controlled Acquired Companies), shall indemnify, defend, save and hold the EME Indemnified Parties harmless from and against: (i) except to the extent (A) EME is otherwise required to indemnify the Purchaser Indemnified Parties for such Tax pursuant to Section 11.5(a) or (B) resulting from actions taken by, at the instruction of or with the prior written consent of an EME Indemnified Party, all liability for Taxes of and in respect of the Controlled Acquired Companies; (ii) all liability for Taxes attributable to a Purchaser Tax Act, including all liability for Taxes resulting from the Purchaser making an election under Section 338(g) of the Code (unless required to do so by EME pursuant to Section 7.2(b)); and (iii) all liability for any breach of the Purchaser Parties' covenants contained in Article VII and (iv) all costs, losses or expenses (including without limitation reasonable attorneys' or accountants' fees) relating to Taxes or liabilities described in clauses (i) to (iii) of this Section 11.5(b).

(i) The periodic Taxes of and in respect of the Acquired Companies that are not Income Taxes (e.g., property Taxes) for the portion of any Straddle Period ending on the Closing Date (the "Pre-Closing Tax Period") shall be computed based upon the ratio of the number of days in the Pre-Closing Tax Period and the number of days in the entire taxable period; and

(ii) Income Taxes of and in respect of the Acquired Companies for the Pre-Closing Tax Period shall be computed as if such taxable period ended as of the close of business on the Closing Date and, in the case of any Taxes of and in respect of the Acquired Companies attributable to the ownership by such companies of any equity interest in any partnership or other "flowthrough" entity, as if a taxable period of such partnership or other "flowthrough" entity ended as of the close of business on the Closing Date.

(d) Payment. Payment by the Indemnifying Party of any amount due under the provisions of this Section 11.5 shall be made within ten (10) Business Days following written notice by the Indemnified Party that payment of such amount to the appropriate Tax Authority is due; provided, that the Indemnifying Party shall not be required to make any payment earlier than five (5) Business Days before it is due to the appropriate Tax Authority. In the case of a Tax that is contested under Section 11.5(e) below, payment of the Tax to the appropriate Tax Authority shall not be considered to be due earlier than the date a final determination to such effect is made by the appropriate Tax Authority or court, provided that the Indemnifying Party shall provide the funds for any deposit, bond or similar outlay during the conduct of such contest.

(e) Tax Indemnity Procedures.

(i) If a claim shall be made by any taxing authority (a "Tax Claim") which, if successful, might result in an indemnity payment to the Purchaser Indemnified Parties or the EME Indemnified Parties pursuant to Section 11.5, the Indemnified Party shall promptly notify the Indemnifying Party of such claim no later than thirty (30) Business Days after such Tax Claim is made, or otherwise the Indemnifying Party will be released from any indemnification obligation hereunder with respect to such Tax Claim to the extent of the actual and material prejudice caused provided that this clause (i) shall not apply to a Tax Claim falling within Section 11.5(e)(ii) below.

(ii) With respect to any Tax Claim relating to a taxable period ending on or before the Closing Date or relating to or affecting a Consolidated Tax Return of EME or its Affiliates (including, for the avoidance of doubt, any Tax Return of a relevant consolidated or multiple entry consolidated group for a Straddle Period), EME shall control all proceedings and may make all decisions taken in connection with such Tax Claim (including selection of counsel) and, without

limiting the foregoing, may in its sole discretion pursue or forego any and all administrative appeals, proceedings, hearings and conferences with any taxing authority with respect thereto, and may, in its sole discretion, either pay the Tax claimed and ▇▇▇ for a refund where applicable Law permits such refund suits or contest the Tax Claim in any permissible manner. The Purchaser shall be entitled to be informed of such Tax Claim within a reasonable time after such Tax Claim is asserted and the developments with respect to such Tax Claim at any administrative meeting, conference, hearing or other proceeding. Without limitation to Section 11.5(e)(iii), EME shall not settle any Tax Claim if the terms of such settlement would materially prejudice the Tax position of the Purchaser or any of its Affiliates (including, after Closing, the Controlled Acquired Companies) at any time on or after the Closing Date.

(iii) Except as otherwise provided in Section 11.5(e)(ii), EME and the Purchaser shall jointly control and participate in all proceedings taken in connection with any Tax Claim relating to Taxes of and in respect of the Controlled Acquired Companies for any Straddle Period. Neither EME nor Purchaser shall settle any such Tax Claim without the prior written consent of the other, which shall not be unreasonably withheld.

(iv) Except as otherwise provided in Sections 11.5(e)(i) and (ii), Purchaser shall control all proceedings with respect to Taxes for any taxable period beginning after the Closing Date.

(f) Timing Adjustment. In the event that a final determination (which shall include the execution of an United States Internal Revenue Service Form 870-AD or successor or similar form) results in a timing difference (e.g., an acceleration of income or delay of deductions) that would increase EME's liability for Taxes pursuant to this Section 11.5 or results in a timing difference (e.g., an acceleration of deductions or delay of income) that would increase the Purchaser's liability for Taxes pursuant to this Section 11.5, the Purchaser or EME, as the case may be, shall promptly make payments to EME or the Purchaser as and when the Purchaser or EME, as the case may be, actually realizes any Tax benefits as a result of such timing difference (or under such other method for determining the present value of any such anticipated Tax benefits as agreed to by the Parties). Such Tax benefit for U.S. or foreign federal, state, provincial and local Income Tax purposes shall be computed for any year using Purchaser's or EME's, as the case may be, actual Tax liability with and without giving effect to such timing difference.

11.6 Indemnity Payments Treated as Adjustment to the Aggregate Purchase Price. Any indemnity payments, including Tax indemnity payments, pursuant to this Agreement are intended by the Parties and shall be treated by the Parties on their Tax Returns as payments made by the respective Seller or Purchaser Party, as the case may be, and as adjustments to the Aggregate Purchase Price, unless any final law or Tax determination causes any such payment not to be treated as an adjustment to the Aggregate Purchase Price. In the event that the receipt of a payment under Section 11.3 or 11.5 results in any Tax to the recipient, the Indemnifying Party shall increase the amount of such payment to the extent necessary such that the amount received by the Indemnified Party, net of Taxes, is the same as the amount the Indemnified Party would have received if such Tax had not been imposed; provided, the Indemnified Party shall use its best efforts to reduce such Taxes and, provided further, if any such Tax is refunded to or otherwise recovered by the recipient, such refund or recovery shall be for the account of and paid over to the Indemnifying Party.

ARTICLE XII.
MISCELLANEOUS

12.1 Construction; Conflicts. This Agreement and any documents or instruments delivered pursuant hereto shall be construed without regard to the identity of the Person who drafted the various provisions of the same. Each and every provision of this Agreement, each Related Agreement and such other documents and instruments shall be construed as though the Parties participated equally in the

drafting of the same. Consequently, any rule of construction that a document is to be construed against the drafting party shall not be applicable either to this Agreement, any Related Agreement or such other documents and instruments. In the event of any conflict between this Agreement and any Related Agreement or Foreign Implementing Agreement, this Agreement shall prevail unless either (a) this Agreement is separately amended in accordance with the provisions hereof or (b) EME and the Purchaser are also parties to such Related Agreement or Foreign Implementing Agreement and such Related Agreement or Foreign Implementing Agreement expressly provides that it prevails over this Agreement.

12.2 Expenses. The Sellers, on the one hand, and the Purchaser Parties, on the other hand, shall each bear their own respective costs and expenses incurred in connection with the negotiation and execution of this Agreement and the Related Agreements and each other agreement, document and instrument contemplated hereby or thereby and the consummation of the Contemplated Transactions.

12.3 Incorporation of Exhibits and Schedules. All of the Exhibits and Schedules identified in this Agreement are incorporated herein by reference and made a part hereof.

12.4 Binding Effect; Assignment.

(a) This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns. Except as expressly provided otherwise in this Agreement, nothing in this Agreement will be construed as giving any Person, other than the Parties and their successors and permitted assigns, any right, remedy or claim under or in respect of this Agreement or any provision hereof.

(b) Except as expressly set forth in Section 1.5 and subject to Section 12.4(c), no assignment of this Agreement or of any rights or obligations hereunder may be made by EME or any Purchaser Party (by operation of Law or otherwise) without the prior written consent of EME, in the case of assignment by any Purchaser Party, and the Purchaser, in the case of assignment by EME (which consent may be granted or withheld in either EME's or the Purchaser's sole discretion), and any attempted assignment without the required consent shall be void.

(c) The Purchaser may charge or assign the benefit of this Agreement and any Related Agreement to any bank or financial institution or other Person by way of security for the purposes of or in connection with the financing or refinancing (whether in whole or in party) by the Purchaser of the acquisition of the Shares and the Owner Notes under this Agreement or any Related Agreement provided that (i) the Purchaser Parties nonetheless shall remain responsible, and liable to the Sellers, for the performance of all of their respective obligations hereunder and thereunder and (ii) the Sellers will have no greater obligation or liability to the chargee or assignee than it would have had to the Purchaser in the absence of any such charge or assignment. Without limitation to the foregoing, any such bank, financial institution or Person (or any administrative receiver appointed by any of the foregoing or any other Person appointed to enforce any such security) may charge or assign such rights on, for the purpose of or in connection with, any enforcement of the security under such finance arrangements.

Subject to Section 12.4, each Purchaser Party for itself and for its Subsidiaries, Affiliates, successors and permitted assigns hereby unconditionally and irrevocably waives any rights of set-off, netting, offset, recoupment, or similar rights that such Purchaser Party or any of its respective Subsidiaries, Affiliates, successors and permitted assigns has or may have with respect to the payment of the Purchase Price or any other payments to be made by any Purchaser Party or Purchaser Designee pursuant to this Agreement or any other document or instrument delivered by any Purchaser Party or Purchaser Designee in connection herewith.

12.6 Time of Essence. With regard to all dates and time periods set forth or referred to in this Agreement, time is of the essence. The Parties acknowledge that each will be relying upon the timely

performance by the others of their obligations hereunder as a material inducement to each Party's execution of this Agreement.

12.7 Entire Agreement; Amendments and Waivers.

(a) This Agreement, the Related Agreements and the EME Confidentiality Agreement represent the entire understanding and agreement between the Parties with respect to the subject matter hereof and thereof and, except as expressly provided for herein, supersede all prior understandings and agreements, whether oral or written, between the Parties with respect to the subject matter hereof and thereof. There are no representations, warranties, agreements, arrangements or understandings, oral or written, between the Parties relating to the subject matter of this Agreement which are not fully expressed herein or therein.

(b) This Agreement can be amended, supplemented or changed, and any provision hereof can be waived, only by a written instrument making specific reference to this Agreement signed by the Party against whom enforcement of any such amendment, supplement, modification or waiver is sought. No action taken pursuant to this Agreement, including any investigation by or on behalf of any Party, shall be deemed to constitute a waiver by the Party taking such action of compliance by any Party with any representation, warranty, covenant or agreement contained herein. The waiver by any Party of a breach of any provision of this Agreement shall not operate or be construed as a further or continuing waiver of such breach or as a waiver of any other or subsequent breach. No failure on the part of any Party to exercise, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such Party preclude any other or further exercise thereof or the exercise of any other right, power or remedy. Any consent to be given by the Sellers hereunder may be given on their behalf by EME acting as agent.

12.8 Governing Law. THIS AGREEMENT, THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT, AND ANY CLAIM OR CONTROVERSY DIRECTLY OR INDIRECTLY BASED UPON OR ARISING OUT OF THIS AGREEMENT OR THE CONTEMPLATED TRANSACTIONS (WHETHER BASED ON CONTRACT, TORT, OR ANY OTHER THEORY), INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE, SHALL IN ALL RESPECTS BE GOVERNED BY AND INTERPRETED, CONSTRUED AND DETERMINED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO ANY CONFLICTS OF LAW PROVISION THAT WOULD REQUIRE THE APPLICATION OF THE LAW OF ANY OTHER JURISDICTION).

Any and all process may be served in any action, suit or proceeding arising in connection with this Agreement or the Related Agreements by complying with the provisions of Section 12.12. Such service process shall have the same effect as if the party being served were a resident in the State of New York and had been lawfully served with such process in such jurisdiction. The Parties hereby waive all claims of error by reason of such service. Nothing herein shall affect the right of any Party to service of process in any other manner permitted by Law or to commence legal proceedings or otherwise proceed against the other in any other jurisdiction to enforce judgments or rulings of the aforementioned courts.

(b) The Parties shall each provide the Expert with all information that the Expert reasonably requests (having regard to the Expert's terms of reference) and the Expert shall be entitled (to the extent he considers appropriate) to base his determination on such information.

This Agreement may be executed in any number of counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument.
