Notice to US investors

The Consideration Shares are expected to be issued in the United States in reliance upon the exemption from the registration requirements of the US Securities Act provided by section 3(a)(10) thereof.

For the purposes of qualifying for the exemptions from the registration requirements of the US Securities Act afforded by Section 3(a)(10), TalkTalk will advise the Court through counsel that the Court's sanction of the Scheme will be relied upon by the Offeror as an approval of the Scheme following a hearing on the fairness of the terms and conditions of the Scheme to TalkTalk Shareholders at which hearing all such shareholders are entitled to appear in person or through counsel to support or oppose the sanctioning of the Scheme and with respect to which notification has been given to all TalkTalk Shareholders.

TalkTalk Shareholders who are, or will be, affiliates of the Offeror after the Effective Date will be subject to certain US transfer restrictions relating to the Consideration Shares received pursuant to the Scheme. Otherwise, the Consideration Shares generally should not be treated as "restricted securities" within the meaning of Rule 144(a)(3) under the US Securities Act and persons who receive securities under the Scheme (other than certain affiliates of the Offeror) may resell them without restriction under the US Securities Act.

The receipt of Consideration Shares or cash pursuant to the Acquisition by a US TalkTalk Shareholder will be a taxable transaction for US federal income tax purposes, and may also be a taxable transaction under applicable state and local tax laws, as well as foreign and other tax laws.  Each TalkTalk Shareholder is urged to consult their independent professional advisor immediately regarding the tax consequences of the Acquisition. US TalkTalk Shareholders should also read sub-paragraph 18.2 of Part II (Explanatory Statement) of the Scheme Document.

It may be difficult for US TalkTalk Shareholders to enforce their rights and claims arising out of the US federal securities laws, since the Offeror and TalkTalk are located in countries other than the United States, and some or all of their officers and directors may be residents of countries other than the United States. US TalkTalk Shareholders 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 judgment.

None of the securities referred to in this announcement have been approved or disapproved by the SEC, any state securities commission in the United States or any other US regulatory authority, nor have such authorities passed upon or determined the adequacy or accuracy of the information contained in this document.  Any representation to the contrary is a criminal offence in the United States.
