Overseas jurisdictions

The release, publication or distribution of this Announcement in or into jurisdictions other than the United Kingdom may be restricted by law and therefore any persons who are subject to the laws of any jurisdiction other than the United Kingdom should inform themselves about, and observe, any applicable legal or regulatory requirements. 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 law, the rules of the London Stock Exchange, the AIM Rules 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 of England & Wales.

Copies of this Announcement and any formal documentation relating to the Acquisition are not being, and must not be, directly or indirectly, mailed, transmitted or otherwise forwarded, distributed or sent in or into or from any Restricted Jurisdiction or any other jurisdiction where to do so would constitute a violation of the laws of that jurisdiction, and persons receiving such documents (including custodians, nominees and trustees) must not mail or otherwise forward, distribute or send such documents in or into or from any Restricted Jurisdiction. Doing so may render invalid any related purported vote in respect of the Acquisition. If the Acquisition is implemented by way of a Takeover Offer (unless otherwise permitted by applicable law and regulation), the Takeover Offer may not be made directly or indirectly, in or into, or by the use of mails or any means or instrumentality (including, but not limited to, facsimile, e-mail or other electronic transmission or telephone) of interstate or foreign commerce of, or of any facility of a national, state or other securities exchange of any Restricted Jurisdiction and the Takeover Offer may not be capable of acceptance by any such use, means, instrumentality or facilities or from within any Restricted Jurisdiction.

Further details in relation to Vernalis Shareholders in overseas jurisdictions are contained in the Scheme Document.

Notice to US holders of Vernalis Shares and Vernalis ADSs

The Acquisition relates to the shares of an English company and is being made by means of a scheme of arrangement provided for under English company law. A transaction effected by means of a scheme of arrangement is not subject to the tender offer rules or the proxy solicitation rules under the US Exchange Act. Accordingly, the Acquisition is subject to the disclosure requirements and practices applicable in the United Kingdom to schemes of arrangement which differ from the disclosure requirements of United States tender offer and proxy solicitation rules. If, in the future, Ligand UK exercises the right to implement the Acquisition by way of a Takeover Offer and determines to extend such Takeover Offer into the United States, the Acquisition will be made pursuant to applicable UK tender offer rules and securities laws and otherwise in accordance with the requirements of the Code. Accordingly, any such Takeover Offer will be subject to 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 to tender offers made in accordance with US procedures and law. Financial information included in this Announcement and the Scheme Document has been or will be prepared in accordance with accounting standards applicable in the United Kingdom that 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.

It may be difficult for US holders of Vernalis Shares (and Vernalis ADS Holders) to enforce their rights and any claim arising out of the US federal securities laws, since Vernalis is 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 Vernalis Shares and Vernalis ADS Holders 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.

Neither the SEC nor any securities commission of any state 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.

In accordance with normal UK practice and pursuant to Rule 14e-5(b) of the US Exchange Act, Ligand UK or its nominees or brokers (acting as agents) may from time to time make certain purchases of, or arrangements to purchase, Vernalis Shares outside the United States, other than pursuant to the Acquisition, until the date on which the Takeover Offer and/or Scheme 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 News Service of the London Stock Exchange and will be available on the London Stock Exchange website.

A person may also request that all future documents, announcements and information to be sent to that person in relation to the Acquisition should be sent by the party which publishes it in hard copy form.

Disclosure requirements of the Code

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(s) (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(s) must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror(s). 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 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.
