Access to this section of the website may be restricted under securities laws in certain jurisdictions. This notice requires you to confirm certain matters (including that you are not resident in such a jurisdiction), before you may obtain access to the information on this section of the website. These materials are not directed at or accessible by persons resident in any jurisdiction where to do so would constitute a violation of the relevant laws of that jurisdiction.

IMPORTANT INFORMATION

This area of the website (the "Microsite") contains announcements, documents and information (together the "Information") published by International Power plc ("IPR") or Electrabel S.A. ("EBL"), a wholly owned subsidiary of GDF SUEZ S.A. ("GDFS"), relating to the offer by EBL for the entire issued and to be issued share capital of IPR not already owned directly or indirectly by EBL to be implemented by way of scheme of arrangement pursuant to Part 26 of the UK Companies Act 2006 (the "Offer"). The Information is made available in good faith and for information purposes only and is subject to the terms and conditions set out below.

The Information has been made available in order to comply with Rule 30.4 of the UK Takeover Code. The Information disclosed may not be the same as that which would have been prepared in accordance with the laws outside the United Kingdom. The Information is not intended to, and does not, constitute or form any part of an offer to sell or an invitation or the solicitation of an offer to purchase, otherwise acquire, subscribe for, sell or otherwise dispose of, any securities, or the solicitation of a vote or approval in any jurisdiction, pursuant to the Information or otherwise.

The full terms and conditions of the Offer will be set out in the formal Scheme Document. In deciding whether or not to vote in favour of the Offer, shareholders of IPR should rely only on the information contained and procedures described in the formal Scheme Document.

Access to the Microsite

If you would like to view the Microsite, please read this notice carefully. This notice applies to all persons who view the Microsite and, depending on where you are located, may affect your rights or responsibilities. IPR reserves the right to amend or update this notice at any time and you should, therefore, read it in full each time you visit the Microsite. In addition, the contents of the Microsite may be amended at any time in whole or in part at the sole discretion of IPR.

Overseas Persons

As a consequence of legal restrictions, the release, publication or distribution of the Information in certain jurisdictions or to certain persons may be restricted or unlawful. All persons resident or located outside the United Kingdom who wish to view the Microsite must inform themselves of, and observe, any legal or regulatory requirements applicable in their jurisdiction.

If you are resident or located in a country that renders the accessing of the Microsite or parts thereof illegal, whether or not subject to making certain notifications or taking other action, you should not view the Microsite. Unless otherwise determined by IPR and permitted by applicable law and regulation, it is not intended that the Information be accessible by persons resident or located in any jurisdiction where to do so would constitute a violation of the relevant laws of such jurisdiction.

The Offer relates to shares of a UK company and is proposed to be effected by means of a scheme of arrangement under the laws of England and Wales. The Offer will relate to the shares of a UK company that is a 'foreign private issuer' as defined under Rule 3b-4 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). A transaction effected by means of a scheme of arrangement is not subject to proxy solicitation or tender offer rules under the Exchange Act. Accordingly, the Offer is subject to the disclosure requirements, rules and practices applicable in the United Kingdom to schemes of arrangement, which differ from the disclosure requirements of US proxy solicitation or tender offer rules. Financial information included in the relevant documentation will have been prepared in accordance with accounting standards applicable in the United Kingdom that may not be comparable to the financial statements of US companies.

It is your responsibility to satisfy yourself as to the full observance of any relevant laws and regulatory requirements. If you are in any doubt, you should not continue to seek to access the Microsite.

The Information may not be downloaded by any person either in whole or in part where to do so would or may constitute a violation of the relevant laws of such jurisdiction, or subject any person connected with the Offer to any registration or licensing requirement in that jurisdiction.

The Information does not constitute an offer to sell or an invitation or solicitation of any offer to purchase or subscribe for any securities or solicitation of any votes attaching to securities which are the subject of the Offer in any jurisdiction in which such offer or solicitation is unlawful.

Forward looking statements

The Information may contain statements about IPR and EBL that are or may be forward looking statements. All statements other than statements of historical facts included in this announcement may be forward looking statements. Without limitation, any statements preceded or followed by or that include the words "targets", "plans", "believes", "expects", "aims", "intends", "will", "may", "anticipates", "estimates", "projects" or words or terms of similar substance or the negative thereof, are forward looking statements. Forward looking statements include statements relating to the following: (i) future capital expenditures, expenses, revenues, earnings, synergies, economic performance, indebtedness, financial condition, dividend policy, losses and future prospects; (ii) business and management strategies and the expansion and growth of IPR, GDFS and EBL's operations and potential synergies resulting from the Offer; and (iii) the effects of government regulation on IPR, GDFS and EBL's business.

Such forward looking statements involve risks and uncertainties that could significantly affect expected results and are based on certain key assumptions. Many factors could cause actual results to differ materially from those projected or implied in any forward looking statements. Due to such uncertainties and risks, readers are cautioned not to place undue reliance on such forward looking statements, which speak only as of the date hereof. IPR, GDFS and EBL disclaim any obligation to update any forward looking or other statements contained herein, except as required by applicable law.

No statement in this Microsite is intended to constitute a profit forecast for any period and no statement should be interpreted to mean that earnings or earnings per share will necessarily be greater or lesser than those for the relevant preceding financial periods for EBL or IPR as appropriate.
