Notice to US investors

Shareholders of Amerisur ordinarily resident in the US or with a registered address in the US (and any custodian, nominee or trustee holding Amerisur shares for persons in the US or with a registered address in the US) (US Holders) should note that the Offer relates to the securities of an English company and is subject to UK disclosure requirements and practices (which are different from those of the US).

The Offer may be effected by means of a scheme of arrangement or a takeover offer. A scheme of arrangement under English company law is not subject to the tender offer rules under the US Exchange Act of 1934 and the rules and regulations promulgated thereunder (as amended) (the US Exchange Act), and the proxy solicitation rules under the US Exchange Act would not apply to such an offer. A scheme of arrangement would be subject to UK disclosure requirements and practices, which are different from the disclosure requirements of the US tender offer and proxy solicitation rules.

US Holders may not be able to sue a non-US company or its officers or directors in a non-US court for violations of 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.
