Overseas jurisdictions

The release, publication or distribution of this Announcement in or into, and the availability of the Acquisition to persons who are residents, citizens of nationals of, jurisdictions other than the United Kingdom or Jersey may be restricted by law and therefore any persons who are subject to the laws of any jurisdiction other than the United Kingdom or Jersey should inform themselves about, and observe any applicable legal or regulatory requirements. In particular, the ability of persons who are not resident in the United Kingdom or Jersey to accept or procure the acceptance of the Acquisition (when made) may be affected by the laws of the relevant jurisdictions in which they are located. Any failure to comply with the applicable 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 purpose of complying with English and Jersey law, the Code, the Market Abuse Regulation and the Disclosure Guidance and Transparency Rules 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 or Jersey.

The receipt of cash pursuant to the Acquisition by Wentworth Shareholders may be a taxable transaction under applicable national, state and local, as well as foreign and other tax laws. Each Wentworth Shareholder is urged to consult their independent professional adviser regarding the tax consequences of the Acquisition applicable to them.

Further details in relation to Wentworth Shareholders in overseas jurisdictions will be contained in the Scheme Document.

The Acquisition will be subject to the applicable requirements of the Code, the Panel, the Jersey Companies Law, the London Stock Exchange and the FCA.

Notes to US investors in Wentworth

Shareholders in the United States should note that the Acquisition relates to the shares of a Jersey company and is proposed to be made by means of a scheme of arrangement provided for under, and governed by, Jersey 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 and Jersey 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 accounting standards applicable in the UK and Jersey 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. If M&P exercises its right to implement the Acquisition by way of a Takeover Offer and determines to extend the offer into the United States, such offer will be made in compliance with applicable United States securities laws and regulations.

Wentworth and M&P are organised under the laws of Jersey and France respectively. Some or all of the officers and directors of Wentworth and M&P are residents of countries other than the United States. It may not be possible to sue Wentworth and M&P in a non-US court for violations of US securities laws. It may be difficult to compel Wentworth, M&P and their respective affiliates to subject themselves to the jurisdiction and judgment of a US court.

In accordance with normal UK practice and pursuant to Rule 14e-5(b) of the US Exchange Act, M&P or its nominees, or its brokers (acting as agents), may from time to time make certain purchases of, or arrangements to purchase Wentworth Shares outside of the United States, other than pursuant to the Acquisition, until the date on which the Acquisition becomes Effective, lapses or is otherwise withdrawn. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Any information about such purchases will be disclosed as required in the UK, will be reported to the Regulatory Information Service of the London Stock Exchange and will be available on the London Stock Exchange website at http://www.londonstockexchange.com/exchange/news/market-news/market-news-home.html.

This Announcement does not constitute or form a part of any offer to sell or issue, or any solicitation of any offer to purchase, subscribe for or otherwise acquire, any securities in the United States.

Neither the US Securities and Exchange Commission nor any securities commission of any state or other jurisdiction of the United States has approved the Acquisition, passed upon the fairness of the Acquisition, or passed upon the adequacy or accuracy of this Announcement. Any representation to the contrary is a criminal offence in the United States.

Disclosure requirements

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 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% 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. 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.
