Additional information for US investors

The Offer relates to the shares of an English company and is being made by means of a contractual takeover offer under the Takeover Code and under the laws of England and Wales. The Cash Offer will be made in the United States pursuant to all applicable laws and regulations, including, to the extent applicable, Section 14(e) and Regulation 14E under the US Exchange Act and otherwise in accordance with the requirements of the Takeover Code. Accordingly, the Cash Offer will be subject to the disclosure and other procedural requirements, including with respect to withdrawal rights, offer timetable, settlement procedures and timing of payments that are different from those applicable under US domestic tender offer procedures and law. US holders of essensys Shares should note that essensys is not listed on a US securities exchange and is not subject to the periodic reporting requirements of the US Exchange Act, and is not required to, and does not, file any reports with the US Securities and Exchange Commission thereunder. The Cash Offer will be made in the United States by Bidco and no one else.

If, in the future, Bidco exercises its right to implement the Cash Offer by way of a Scheme, which is to be made into the United States, such Scheme will be made in compliance with the applicable U.S. law and regulation.

Furthermore, the payment and settlement procedure with respect to the Cash Offer will comply with the relevant United Kingdom rules, which differ from US payment and settlement procedures, particularly with regard to the date of payment of consideration.

essensys Shareholders located or resident in the US or who are otherwise US persons as such term is defined in Regulation S under the US Securities Act) will not be permitted to elect receipt of the New Bidco Shares pursuant to the Alternative Offer. No offer of such New Bidco Shares is being made in the US, and any purported election to receive New Bidco Shares pursuant to the Alternative Offer by essensys Shareholders from the US, or which, at the sole discretion of Bidco, appear to be made in respect of essensys Shares beneficially held by persons located or resident in the US or who otherwise appear to be US persons will not be accepted. Accordingly, essensys Shareholders located or resident in the US or who are otherwise US persons will receive cash pursuant to the Cash Offer, and no New Bidco Shares will be issued to any such essensys Shareholder. The New Bidco Shares have not been and will not be registered under the US Securities Act or under US securities laws, and will not be listed on any stock exchange in the US, and may not be offered, sold or delivered, directly or indirectly, in, into or from the US absent registration or an applicable exemption from registration requirements of the US Securities Act and applicable state securities laws.

Non-US essensys Shareholders will be deemed, by electing receipt of the New Bidco Shares pursuant to the Alternative Offer, to represent and warrant, on behalf of themselves and any person on whose behalf they beneficially hold their essensys Shares, that they: (i) are not located or resident in the US or otherwise a US person; and (ii) are not electing receipt of New Bidco Shares pursuant to the Alternative Offer with a view to, or for offer or sale of New Bidco Shares in connection with, any distribution thereof (within the meaning of the US Securities Act) in the US or to US persons.

In accordance with, and to the extent permitted by, the Takeover Code and normal UK market practice, Bidco, its affiliates, their advisors and nominees or brokers (acting as agents) may make certain purchases of, or arrangements to purchase, essensys Shares outside the Offer, such as in open market purchases or privately negotiated purchases, during the offer period and the period in which the Offer remains open for acceptance. If such purchases or arrangements to purchase were to be made, they would be made outside the US and would comply with applicable law and regulation, including those of the United Kingdom and the US Exchange Act. Any such purchases by Bidco or its affiliates will not be made at prices higher than the price of the Offer provided in this Announcement unless the price of the Offer is increased accordingly. Any information about such purchases or arrangements to purchase shall be disclosed as required under United Kingdom laws and will be available to all investors (including US investors) via the Regulatory Information Service and shall be available on the London Stock Exchange website at www.londonstockexchange.com. To the extent that such information is required to be publicly disclosed in the United Kingdom in accordance with applicable regulatory requirements, this information will, as applicable, also be publicly disclosed in the United States.

It may be difficult for US holders of essensys Shares to enforce their rights and any claim arising out of the US securities laws in connection with the Offer, since Bidco and essensys are located in a non-US jurisdiction, and some or all of their officers and directors may be residents of a non-US jurisdiction. US holders of essensys Shares may not be able to sue a non-US company or its officers or directors in a non-US court for violations of the US securities laws. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court's judgement.

The financial information included in this Announcement has been prepared in accordance with accounting standards applicable in the United Kingdom and thus 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 US ("US GAAP"). US GAAP differs in certain significant respects from accounting standards applicable in the United Kingdom. None of the financial information in this Announcement has been audited in accordance with auditing standards generally accepted in the United States or the auditing standards of the Public Company Accounting Oversight Board (United States).

Neither the Offer nor this Announcement have been approved or disapproved by the US Securities and Exchange Commission, any state securities commission in the United States or any other US regulatory authority, nor have such authorities approved or disapproved or passed judgement upon the fairness or the merits of the Offer or the New Bidco Shares, or determined if the information contained in this Announcement is adequate, accurate or complete. Any representation to the contrary is a criminal offence in the United States. The receipt of cash pursuant to the Cash Offer by a US holder as consideration for the transfer of its essensys Shares pursuant to the Cash Offer will likely be a taxable transaction for US federal (and applicable state and local) income tax purposes .  EACH US HOLDER IS URGED TO CONSULT THEIR TAX ADVISOR REGARDING THE TAX CONSEQUENCES TO THEM OF THE RECEIPT OF CASH IN EXCHANGE FOR THEIR ESSENSYS SHARES PURSUANT TO THE CASH OFFER.
