Your attention is drawn to certain UK dealing disclosure requirements in relation to the Transaction. These disclosure requirements are set out in Rule 8 of the City Code.

Under the provisions of Rule 8.3 of the City Code, if any person is, or becomes, "interested" (directly or indirectly) in 1 per cent. or more of any class of "relevant securities" of LSE, all "dealings" in any "relevant securities" of LSE (including by means of an option in respect of, or a derivative referenced to, any such "relevant securities") must be publicly disclosed by no later than 3.30 pm (London time) on the London business day following the date of the relevant transaction. This requirement will continue until the date on which the Ordinary Offer becomes, or is declared, unconditional as to acceptances, lapses or is otherwise withdrawn or upon the "offer period" otherwise ending. If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire an "interest" in "relevant securities" of LSE, they will be deemed to be a single person for the purposes of Rule 8.3.

Under the provisions of Rule 8.1 of the City Code, all "dealings" in "relevant securities" of LSE by NASDAQ or NAL, or by any of their respective "associates", must be disclosed by no later than 12.00 noon (London time) on the London business day following the date of the relevant transaction.

A disclosure table, giving details of the companies in whose "relevant securities" "dealings" should be disclosed, and the number of such securities in issue, can be found on the Takeover Panel's website at www.thetakeoverpanel.org.uk.

"Interests in securities" arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in the price of securities. In particular, a person will be treated as having an "interest" by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities.

Terms in quotation marks are defined in the City Code, which can also be found on the Panel's website. If you are in any doubt as to whether or not you are required to disclose a "dealing" under Rule 8, you should consult the Panel.
