Until the Second Completion Date, the Indemnification Amount shall be equal to the amount as shall be received by the Indemnifying Parties on the First Completion Date (directly in escrow).

(a) An Indemnified Party shall promptly notify the Existing Partners from whom indemnification is sought under this Article 9 (for purposes of this Article 9, the "Indemnifying Parties") of any Stranded Cost that it believes to be for its account (such determination, a "Stranded Cost Determination" and such notice, a "Stranded Cost Claim Notice"). Any Stranded Cost Claim Notice shall include an estimate, to the extent feasible, of the amount of Stranded Costs for which the Company believes it is obligated (which estimate shall not be conclusive of the final amount of that claim): provided, however, that the failure to promptly deliver a Stranded Cost Claim Notice shall not relieve the Indemnifying Parties of their obligations to the Indemnified Party with respect to Stranded Costs. Within 15 days after receipt of any Stranded Cost Claim Notice (the "Election Period"), the Indemnifying Parties shall notify the Indemnified Party whether the Indemnifying Parties desire, at the sole cost and expense of the Indemnifying Parties, to contest or challenge the validity of the relevant Stranded Cost Determination. For purposes of this Article 9, the Indemnifying Parties shall act jointly and not separately. If the Indemnifying Party shall fail to notify the Indemnified Party that it desires to contest or challenge the Stranded Cost Determination, the Indemnifying Party shall pay the amount of Stranded Costs covered by the relevant Stranded Cost Determination. (b) If the Indemnifying Parties notify the Indemnified Party within the Election Period that the Indemnifying Parties elect to contest or challenge the validity of the Stranded Cost Determination, then the Indemnifying Parties shall have the right to contest or challenge on behalf of the Indemnified Parties the validity, at their sole cost and expense, that Stranded Cost Determination by all appropriate proceedings, which proceedings shall be prosecuted diligently by the Indemnifying Parties to a final conclusion or settled at the discretion of the Indemnifying Parties in accordance with this Article 9.2. (c) Notwithstanding Article 9.2(b), the Indemnifying Parties shall not have the right to contest or challenge the validity of a Stranded Cost Determination if, in the reasonable judgment of the Indemnified Party, pursuing such contest or challenge would (i) result in the loss 9 10 of any material rights or licenses of the Company or any of its Affiliates or (ii) result in any injunction or other governmental, judicial or arbitral directive being imposed on the Company or any of its Affiliates that materially interferes with the existing or proposed business of the Companies. (d) The Indemnified Party will cooperate with the Indemnifying Parties in any contest to or challenge of a Stranded Cost Determination; provided, however, that the Indemnifying Parties shall not enter into any settlement with respect to any Stranded Cost Determination that (i) purports to limit the activities of, or otherwise restrict in any way, any Indemnified Party or any Affiliate of any Indemnified Party, (ii) results in any liens being imposed on the properties or assets of the Company or any of its Affiliates, (iii) impairs any material business relationship maintained by the Company or any of its Affiliates, (iii) results in penalties being owed by the Company or any of its Affiliates, (iv) results in the loss of any material rights or licenses of the Company or any of its Affiliates or (v) results in any injunction or other governmental, judicial or arbitral directive being imposed on the Company or any of its Affiliates that materially interferes with the existing or proposed business of the Company and its Affiliates or (vi) would involve amounts that exceed the amount of indemnity to which the Indemnified Parties are entitled under this Article 9 without the prior consent of that Indemnified Party. The Indemnified Party is hereby authorized, to file during the Election Period, with prior written consent of the Indemnifying Parties, any motion, answer or other instrument that the Indemnified Parties shall deem necessary or appropriate to protect its interests or those of the Indemnifying Parties. The Indemnified Parties may participate in, but not control, any defense or settlement of any Stranded Cost Determination controlled by the Indemnifying Parties pursuant to this Article 9.2. (e) If the Indemnifying Parties (i), within the Election Period, fail to notify the Indemnified Party that the Indemnifying Parties elect to contest or challenge any Stranded Cost Determination or (ii) elect to contest or challenge a Stranded Cost Determination but fail diligently and promptly to contest, challenge or settle the Stranded Cost Determination, then the Indemnified Party shall have the right, but not the obligation, to contest or challenge, at the sole cost and expense of the Indemnifying Parties, the Stranded Cost Determination by all appropriate proceedings, which proceedings shall be promptly and vigorously prosecuted by the Indemnified Party to a final conclusion or settlement. The Indemnified Party shall have full 10 11 control of any such defense and proceedings. The Indemnifying Parties may participate in, but not control, any proceeding or settlement controlled by the Indemnified Party pursuant to this Article 9.2(e), and the Indemnifying Parties shall bear their own costs and expenses with respect to that participation. (f) The Indemnified Parties shall not (i) enter into any definitive settlement agreement or (ii) waive any rights with respect to Stranded Costs without the prior written consent of the Indemnifying Parties. (g) The Company shall keep the New Partner and the Existing Partners (i) fully informed of any actions taken by the Company with respect to settlement proposals with respect to Stranded Costs and (ii) shall provide the Existing Partners an opportunity to participate in any negotiations regarding the settlement of such costs. Subject to the limitations in Article 9.2(d), the Existing Partners shall be entitled to assume a primary role in such negotiations; provided, however, that (i) the Existing Partners first agree to designate a joint representative for that purpose and (ii) the Company shall be entitled to consent to the designation of such representative (which consent shall not be unreasonably withheld). (h) Payments of all amounts owing by an Indemnifying Party pursuant to this Article 9 shall be made within 30 days after the date on which the Stranded Cost subject to the Stranded Cost Claim Notice shall have become final and binding on the Indemnifying Party and the Indemnified Parties. Any overdue payment under this Article 9 shall bear interest at the rate of Euribor + 2% per annum (based on a 360- day year) from (and including) the due date until (but excluding) the date the full payment is actually received by the Indemnified Parties. Any interest accrued pursuant to the preceding sentence shall be due and payable on the date the original amount owing is paid. 9.2a In the event that the Indemnified Parties shall have received any amounts pursuant to this Article 9 with respect to Stranded Cost, the Indemnified Parties shall utilise such amounts exclusively for the payment of the Stranded Costs concerned. 9.3 The obligations of each of the Indemnifying Parties under this Article 9 shall only be payable at 1/3 (in words: one-third) of the amounts due under this Article 9. The contractual obligation to indemnify set forth in this Article 9 shall not be subject to limitations specified in Section 13.6 of the Share Purchase Agreement. 11 12 9.4 Payment of any obligations, now existing or hereafter accruing, of the Indemnified Parties under this Article 9 shall be secured through an escrow account (the "Escrow Account") in form and substance satisfactory to the Indemnified Parties. The Existing Partners shall maintain such account through December 31, 2003. The maximum amount subject to these security arrangements shall be NLG 900 million (in words: nine hundred million Dutch Guilders) (the "Escrow Amount"). 9.5 The Stranded Costs for district heating contracts which have been allocated to the Company pursuant to the Act shall be calculated only in accordance with the formulas set out in Appendix B and for the applicable heat sale volumes under each contract. The Company's Stranded Costs for import or other Stranded Cost contracts assigned to or assumed by the Company shall be calculated as the difference between the contract price and market price of the total volume for the period. The other Stranded Costs assets and liabilities assigned to the Company will be calculated on the basis of a valuation method to be agreed between the Indemnified Parties and the Indemnifying Parties. If no agreement can be reached within 20 days, an independent investment bank or accounting firm or similar expert shall be appointed by the Parties in order to carry out a valuation. If the parties are unable to reach an agreement on the basis of the advice from the independent expert, then the dispute will be decided by arbitration in accordance with the Dutch Arbitration Institute ("NAI"). 9.6 With due observance of Article 9.7, a definitive and final amount will be determined for (i) district heating contracts on December 31, 2000, and (ii) import or other Stranded Costs contracts assigned or assumed by on December 31, 2002; unless the Existing Partners notify the Company that they will not seek to establish a final amount and (iii) other Stranded Costs assets and liabilities of the Company at the earlier of 30 days following the assignment or sale of such liabilities or assets or 31 December 2002. 9.6.1 The net present value of the district heating contracts shall be determined by discounting the yearly amounts as defined in Article 9.5 for the remaining years of the contract. 9.6.2 The net present value of the import and other Stranded Cost contracts shall be determined by discounting the yearly estimate of costs as defined in Article 9.5 for the remaining years of each contract, taking into account the price indexes, the flexibility of use and other optimisation opportunities arising from such contracts. 9.6.3 The value of the other Stranded Cost assets and liabilities other than the contracts described in Article 9.5 allocated to the Company, shall be calculated on 12 13 the basis of a valuation method to be agreed between the Indemnified Parties and the Indemnifying Parties. If no agreement can be reached within 20 days, an independent investment bank or accounting firm or similar expert shall be appointed by the Parties in order to carry out a valuation. If the parties are unable to reach an agreement on the basis of the advice from the independent expert, then the dispute will be decided by arbitration in accordance with the Dutch Arbitration Institute ("NAI"). If no determination of Stranded Costs with respect to the foregoing contracts, assets or liabilities has been made that has become binding and definitive for the Company, the Parties will jointly designate an independent investment banking firm and/or other firm of international reputation having special expertise in the electric sector. For the purpose of calculating a net present value, a discount rate of 7% will be used. If the parties are unable to reach an agreement on the basis of the advice from the independent expert, then the dispute will be decided by arbitration in accordance with the Dutch Arbitration Institute ("NAI"). Any changes or expenses incurred in connection with the investment banker's or independent experts' reviews shall be allocated 50% to the New Partner and 50% to the Existing Partners. 9.7 The Indemnification by the Indemnifying Parties pursuant to this Article 9 shall not be limited in time. Any agreements, arrangements or settlements between the Parties including those referred to in Article 9.5 and 9.6 through 9.6.3 shall not affect in any way, whatsoever this Indemnification. 4.9 Article 14.1 of the Share Purchase Agreement shall be amended by adding after the word "terms" and before the period the following: "except that the provisions of Article 9 and Article 13 shall continue to apply in accordance with the terms thereof" 4.10 Article 13.7 of the Share Purchase Agreement shall be amended to read in its entirety as follows: 13.7 (a) The maximum amount of all payments required to be made by the Existing Partners under Article 9 of this Share Purchase Agreement shall not exceed NLG 1.4 billion (in words: one billion four hundred million Dutch Guilders). (b) The maximum amount of all final awards of Damages payable by the Existing Partners with respect to breaches of the Warranties shall not exceed NLG 500 million (in words: five hundred million Dutch Guilders). 13 14 (c) The New Partner may elect by written notice to the Existing Partners to reallocate any unused portion of the NLG 500 million amount referred to under Article 13.7(b) to the Company rather than to the New Partner for use by the Company to offset the burden associated with Stranded Costs. (d) Notwithstanding the foregoing, the following items shall not be included in any calculations under 13.7(a) or 13.7(b) above: (x) any payments to adjust the estimated First Purchase Price to the actual First Purchase Price to reflect changes in net debt and dividend payments as provided in Schedule 2.1.1, (y) any requirements of an Existing Partner to pay expenses under the provisions of the Partnership Documentation including, but not limited to, articles 33.1 and 40.7 of the Partnership Agreement and articles 9.4 and 9.8. 4.11 Article 13.8 of the Share Purchase Agreement shall be amended to read in its entirety as follows: 13.8 The New Partner shall not be entitled to make any claim against the Existing Partners for any Breach or Non-fulfilment unless notice in writing of such claim is given prior to 1 May immediately following the first full Fiscal Year of the Company after the First Completion Date except for a claim for a Breach relating to tax for which the New Partner shall not be entitled to make any claim against the Existing Partners unless written notice of such claim is given prior to the end of the period during which the relevant Dutch tax authorities are competent, according to the laws of the Netherlands, to impose an additional tax assessment ("navorderingsaanslag" or "naheffingsaanslag") concerning events, omissions, acts or behaviours that have taken place prior to the First Completion Date increased by a period of six months. 4.12 Article 13.10 of the Share Purchase Agreement shall be amended to read in its entirety as follows: 13.10 The Existing Partners shall not owe Damages to the New Partner by virtue of this Article 13 or otherwise have obligations towards the New Partner if and to the extent that the Damages ensue from or are related to Stranded Costs. 4.13 The first sentence of Article 13.11 of the Share Purchase Agreement shall be amended to read in its entirety as follows: 13.11 The amount of any award or Damages owed by the Existing Partners to the New Partner shall at the option of the Existing Partners be either paid directly to the New Partner or subtracted from the remaining unpaid amount, if any, of the Second Purchase Price and the Third Purchase Price owed by the New Partner to the Existing Partners. 14 15 4.14 Article 13.12 shall be amended and restated in its entirety as follows: 13.12 Notwithstanding Article 13.13 above, the Province of Utrecht and the Municipality of Utrecht jointly ("niet hoofdelijk"), irrevocably and unconditionally guarantee to the New Partner as guarantor for Pegus prompt performance by Pegus of all its obligations under or in connection with the Share Purchase Agreement and such guarantee shall continue without limitation as to time or as to amount. 4.15 Article 14 shall be amended and restated in its entirety as follows: All Parties to this Agreement waive any rights to (partially) terminate, (partially) annul, (partially) rescind or request the (partial) rescission or (partial) dissolution of this Agreement. 4.16 The New Partner shall undertake and procure that the member of the Management Board nor otherwise designated by the New Partner shall not be dismissed prior to 31 December 2002.
