Overseas jurisdictions

The availability of the New Petroceltic Shares in, and the release, publication or distribution of this announcement in or into, jurisdictions other than the United Kingdom and Ireland may be restricted by law and therefore persons into whose possession this announcement comes who are not resident in the United Kingdom or Ireland should inform themselves about, and observe, any applicable restrictions. Melrose Shareholders and Petroceltic 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.

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

Shareholders in the United States should note that the Merger 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. Moreover 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 the Scheme Circular and the Admission Document has been or will be prepared in accordance with accounting standards applicable in the UK and Ireland 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.

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

Notes regarding New Petroceltic Shares

The New Petroceltic Shares 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 New Petroceltic Shares has been, or will be, lodged with, or registered by, the Australian Securities and Investments Commission. Accordingly, the New Petroceltic Shares 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).

It is expected that the New Petroceltic Shares will be issued in reliance upon the exemption from the registration requirements of the US Securities Act of 1933 (as amended) provided by Section 3(a)(10) thereof.

Disclosure requirements of the Takeover Code (the "Code")

Under Rule 8.3(a) of the Code, any person who is interested in 1% or more of any class of relevant securities of an offeree company or of any paper 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 paper 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 paper 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 paper offeror is first identified. Relevant persons who deal in the relevant securities of the offeree company or of a paper 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% or more of any class of relevant securities of the offeree company or of any paper offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any paper 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 paper offeror, 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 paper 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. You should contact the Panel's Market Surveillance Unit on +44 (0)20 7638 0129 if you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure.
