Overseas jurisdictions

The release, publication or distribution of this announcement in certain jurisdictions may be restricted by law and the availability of the Acquisition to EQ Shareholders who are not resident in the UK may be affected by the laws of the relevant jurisdictions in which they are resident. Persons who are not resident in the UK or who are subject to other jurisdictions should inform themselves of, and observe, any applicable requirements.

Unless otherwise determined by Bidco or required by the Code, and permitted by applicable law and regulation, the Acquisition will not be made available, directly or indirectly, in, into or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction and no person may vote in favour of the Scheme by any such means from within a Restricted Jurisdiction or any other jurisdiction if to do so would constitute a violation of the laws of that jurisdiction. Accordingly, copies of this announcement and all documents relating to the Acquisition are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent in, into or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction, and persons receiving this announcement and all documents relating to the Acquisition (including custodians, nominees and trustees) must not mail or otherwise distribute or send them in, into or from such jurisdictions where to do so would violate the laws in that jurisdiction.

Notice to EQ Shareholders in the US

In the event that the Acquisition is implemented by way of a Takeover Offer and extended into the US, Bidco will do so in satisfaction of the procedural and filing requirements of the US securities laws at that time, to the extent applicable thereto. The Acquisition relates to the shares of an English company and it is proposed to be made by means of a scheme of arrangement provided for under English law. The Scheme will relate to the shares of an English company that is a "foreign private issuer" as defined under Rule 3b-4 under the US Exchange Act. A transaction effected by means of a scheme of arrangement is not subject to the shareholder vote, proxy solicitation and tender offer rules under the US Exchange Act. Accordingly, the Scheme is subject to the disclosure requirements, rules and practices applicable in the UK to schemes of arrangement, which differ from the disclosure requirements and practices of US shareholder vote, proxy solicitation and tender offer rules.

Financial statements, and all financial information included in the relevant documentation, will have been prepared in accordance with accounting standards applicable in the UK and may not be comparable to the financial statements of US companies or other companies whose financial statements are prepared in accordance with US generally accepted accounting principles. However, if Bidco were to elect to implement the Acquisition by means of a Takeover Offer, such Takeover Offer shall be made in compliance with applicable UK and US securities laws and regulations, including the US tender offer rules. Such Takeover Offer would be made in the US by Bidco and no one else. In addition to any such Takeover Offer, Bidco, certain affiliated companies and the nominees or brokers (acting as agents) may make certain purchases of, or arrangements to purchase, shares in EQ outside such Takeover Offer during the period in which such Takeover Offer would remain open for acceptance. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Any information about such purchases or arrangements to purchase shall be disclosed as required in the UK, shall be reported to a Regulatory Information Service and shall be available on the London Stock Exchange website at www.londonstockexchange.com. If such purchases or arrangements to purchase are made they would be made outside the US in compliance with applicable law, including the US Exchange Act.

The receipt of consideration by a US holder for the transfer of its EQ Shares pursuant to the Scheme may have tax consequences in the US and such consequences, if any, are not described herein. Each EQ Shareholder is urged to consult their independent professional adviser immediately regarding the tax consequences of the Acquisition applicable to them, including under applicable US state and local, as well as overseas and other, tax laws.

EQ and Bidco are both incorporated under the laws of England and Wales. Some or all of the officers and directors of EQ are residents of countries other than the US. In addition, some of the assets of Bidco and EQ are located outside the US. As a result, it may be difficult for US holders of EQ Shares to enforce their rights and any claim arising out of the US federal laws or to enforce against them a judgment of a US court predicated upon the securities laws of the UK. US holders of EQ 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.

Forward looking statements

This announcement (including information incorporated by reference in this announcement) may contain certain "forward-looking statements" with respect to Bidco or EQ. These forward-looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward-looking statements often, but do not always, use words such as "anticipate", "target", "expect", "estimate", "intend", "plan", "goal", "believe", "will", "may", "should", "would", "could" or other words or terms of similar meaning or the negative thereof. Forward-looking statements include statements relating to the following: (i) future capital expenditures, expenses, revenues, earnings, synergies, economic performance, indebtedness, financial condition, dividend policy, losses and future prospects; (ii) business and management strategies and the expansion and growth of Bidco's, EQ's, any member of the Bidco Group's or any member of the EQ Group's operations and potential synergies resulting from the Acquisition; and (iii) the effects of global economic conditions and government regulation on Bidco's, EQ's, any member of the Bidco Group's or any member of the EQ Group's business. These forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause actual results, performance or developments to differ materially from those expressed in or implied by such forward-looking statements.

Such forward looking statements are not guarantees of future performance. By their nature, because they relate to events and depend on circumstances that will occur in the future, these forward-looking statements involve known and unknown risks, uncertainties that could significantly affect expected results and are based on certain key assumptions and other factors which may cause actual results, performance or developments to differ materially from those expressed in or implied by such forward-looking statements.

These factors include, but are not limited to, the satisfaction of the conditions to the Acquisition, as well as additional factors, such as changes in political and economic conditions, changes in the level of capital investment, retention of key employees, changes in customer habits, success of business and operating initiatives and restructuring objectives, impact of any acquisitions or similar transactions, changes in customers' strategies and stability, competitive product and pricing measures, changes in the regulatory environment, fluctuations of interest and/or exchange rates and the outcome of any litigation.

These forward-looking statements are based on numerous assumptions regarding present and future strategies and environments. You are cautioned not to place any reliance on such forward-looking statements, which speak only as of the date hereof. All subsequent oral or written forward-looking statements attributable to Siris, Bidco or EQ or any person acting on their behalf are expressly qualified in their entirety by the cautionary statement above. Should one or more of these risks or uncertainties materialise, or should underlying assumptions prove incorrect, actual results may vary materially from those described in this announcement.

None of Siris, Bidco, EQ, or any of their respective associates or directors, officers or advisers, provides any representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements in this announcement will actually occur.

Siris, Bidco and EQ assume no obligation to update publicly or revise forward-looking or other statements contained in this announcement, whether as a result of new information, future events or otherwise, except to the extent legally required.

Disclosure requirements of 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 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 http://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.
