This document constitutes part of a prospectus covering securities that have been registered by Virgin Media, Inc. on Form S-8 under the U.S. Securities Act of 1933, as amended (the “Securities Act”). The issuance of rolled over options is made in an offshore transaction to non-U.S. persons pursuant to an exemption from registration and is therefore not registered under the Securities Act, and no hedging transactions involving rolled over options may be conducted unless in compliance with the Securities Act. The shares issued upon exercise of a rolled over option will be registered on Form S-8 by New Liberty following the Merger.
