Additional U.S. information

In connection with the Possible Offer, Kosmos intends to file certain materials with the U.S. Securities and Exchange Commission (the “SEC“), which may include, among other materials, a proxy statement on Schedule 14A if required. 

The Possible Offer relates to the securities of a UK company and may be implemented by way of a scheme of arrangement provided for under English company law (a “Scheme”). A transaction effected by means of a Scheme is not subject to the tender offer rules under the US Securities Exchange Act of 1934, as amended (the “US Exchange Act”), and the offer of securities of Kosmos as consideration in the Possible Offer (the “Kosmos Securities”) is exempt from the registration requirements of the US Securities Act of 1933, as amended (the “US Securities Act”) or under the laws of any state of other jurisdiction of the United States, and may only be offered, sold or resold in the United States in reliance on an exemption from the registration requirements of the US Securities Act. If the Possible Offer is effected by way of a Scheme, any Kosmos Securities would be expected to be issued to shareholders of Tullow in reliance upon an exemption from the registration requirements of the US Securities Act. In addition, Kosmos Securities may not be registered under any US state securities laws and may only be issued to persons resident in a state pursuant to an exemption from the registration requirements of the securities law of such state. Shareholders who are or will be “affiliates” of Kosmos will be subject to certain transfer restrictions relating to the Kosmos Securities that may be received in connection with the Scheme and sold in the United States. Accordingly, the Possible Offer may be subject to UK procedural and disclosure requirements that are different from those of the United States.  Any financial statements or other financial information included in this Microsite may have been prepared in accordance with non-US accounting standards that may not be comparable to the financial statements 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 Tullow shares to enforce their rights and any claims they may have arising under US federal securities law in connection with the Possible Offer, since Tullow is organised under the laws of a country other than the US, and some or all of its officers and directors may be residents of countries other than the US, and most of the assets of Tullow are located outside of the US.  US holders of shares may not be able to sue Kosmos andTullow or their respective officers or directors in a non-US court for violations of the US securities laws. Further, it may be difficult to compel Kosmos andTullow and their respective affiliates to subject themselves to the jurisdiction or judgment of a US court. 

Alternatively, the Possible Offer may be implemented by way of a takeover offer. If Kosmos exercises its right to implement the Possible Offer by way of a takeover offer, it is expected that such offer will be made in compliance with all applicable US tender offer and securities laws and regulations, including exemptions therefrom, and that the offer and sale of Kosmos Securities will only be made to persons resident or located in the United States pursuant to exemptions from the registration requirements of the US Securities Act (if available). 

In accordance with normal UK practice and pursuant to the US Exchange Act, Kosmos or its nominees, or its brokers (acting as agents), may from time to time make certain purchases of, or arrangements to purchase Tullow shares outside of the US, other than pursuant to the Possible Offer, until the date on which the Possible 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 and the US, and will be reported to a Regulatory Information Service and will be available on the London Stock Exchange website at www.londonstockexchange.com. 

This Possible Offer may be deemed to be solicitation material. In connection with the proposed issuance of Kosmos Securities, Kosmos may, depending on the terms of the Possible Offer, need to file a proxy statement on Schedule 14A with the SEC. Holders of Tullow securities are urged to read any documents related to the Possible Offer filed, furnished or to be filed or furnished with the SEC (including any amendments or supplements thereto), if any, because they will contain important information regarding the Possible Offer and any related offer of securities. Such documents will be available free of charge at the SEC’s website at www.sec.gov. Nothing in this area of the website shall be deemed an acknowledgement that any SEC filing is required or that an offer requiring registration under the US Securities Act may ever occur in connection with the Possible Offer.
