Overseas jurisdictions

The availability of the Loan Notes in, and the release, publication or distribution of this Announcement in or into, jurisdictions other than the United Kingdom may be restricted by law and therefore persons into whose possession this Announcement comes who are not resident in the United Kingdom should inform themselves about, and observe, any applicable restrictions. Hydro Shareholders who are in any doubt regarding such matters should consult an appropriate independent adviser in the relevant jurisdiction without delay. Any failure to comply with such restrictions may constitute a violation of the securities laws of any such jurisdiction. To the fullest extent permitted by applicable law, the companies and persons involved in the Acquisition disclaim any responsibility or liability for the violation of such restrictions by any person.

This Announcement has been prepared for the purposes of complying with English law and the Code and the information disclosed may not be the same as that which would have been disclosed if this Announcement had been prepared in accordance with the laws of jurisdictions outside the United Kingdom.

Notes to US investors in Hydro

This Announcement is not for distribution, directly or indirectly, in or into the United States (including its territories and possessions, any State of the United States and the District of Columbia). This Announcement does not constitute or form a part of any offer or solicitation to purchase or subscribe for securities in the United States.

Shareholders of Hydro in the United States should note that the Acquisition relates to the shares of an English company and is proposed to be made by means of a scheme of arrangement provided for under, and governed by, English law. Neither the proxy solicitation nor the tender offer rules under the US Securities Exchange Act of 1934, as amended, will apply to the Scheme. US shareholders of Hydro will only receive Cash Consideration in connection with the Acquisition and may not elect to receive any Loan Notes.

The Scheme will be subject to the disclosure requirements and practices applicable in the UK to schemes of arrangement, which differ from the disclosure requirements of the US proxy solicitation rules and tender offer rules. Financial information included in this Announcement and the Scheme Document has been or will be prepared in accordance with, where relevant, International Financial Reporting Standards as adopted by the European Union and accounting standards applicable in the UK and may not be comparable to financial information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the United States.

Hydro and Hanover Bidco are each organised under the laws of England. All of the officers and directors of Hydro and Hanover Bidco are residents of countries other than the United States. It may not be possible to sue Hydro or Hanover Bidco in a non-US court for violations of US securities laws. Furthermore, it may be difficult to compel Hydro, Hanover Bidco and their respective affiliates to subject themselves to the jurisdiction and judgment of a US court.

Notes regarding Loan Notes

The Loan Notes to be issued pursuant to the Scheme have not been and will not be registered under the US Securities Act of 1933, as amended, or under the relevant securities laws of any state or territory or other jurisdiction of the United States or the relevant securities laws of Japan and the relevant clearances have not been, and will not be, obtained from the securities commission of any province of Canada. No prospectus in relation to the Loan Notes has been, or will be, lodged with, or registered by, the Australian Securities and Investments Commission. Accordingly, the Loan Notes are not being, and may not be, offered, sold, resold, delivered or distributed, directly or indirectly in or into the United States, Canada, Australia or Japan or any other jurisdiction if to do so would constitute a violation of relevant laws of, or require registration thereof in, such jurisdiction (except pursuant to an exemption, if available, from any applicable registration requirements or otherwise in compliance with all applicable laws).

Disclosure requirements

Under Rule 8.3(a) of the Code, any person who is interested in 1 per cent. or more of any class of relevant securities of an offeree company or of any securities exchange offeror (being any offeror other than an offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must make an Opening Position Disclosure following the commencement of the offer period and, if later, following the announcement in which any securities exchange offeror is first identified. An Opening Position Disclosure must contain details of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3.30 pm (London time) on the 10th Business Day following the commencement of the offer period and, if appropriate, by no later than 3.30 pm (London time) on the 10th Business Day following the announcement in which any securities exchange offeror is first identified. Relevant persons who deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in 1 per cent. or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror. A Dealing Disclosure must contain details of the dealing concerned and of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s), save to the extent that these details have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 pm (London time) on the Business Day following the date of the relevant dealing.

If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4).

Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Takeover Panel's website at www.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the offer period commenced and when any offeror was first identified.
