12. Disclosure of interests in LSE
Save for 54,225,405 LSE Ordinary Shares held by NAL, neither NASDAQ nor NAL (nor any of their respective directors), nor any members of the NASDAQ Group nor, so far as NASDAQ and NAL are aware, any person acting in concert with NASDAQ or NAL, owns or controls or has any interests in securities in any LSE Shares (including pursuant to any long exposure, whether conditional or absolute, to changes in the prices of securities) or any rights to subscribe for or purchase the same, or holds any options (including traded options) in respect of, or has any option to acquire, any LSE Shares or has entered into any derivatives referenced to LSE Shares (Relevant LSE Securities) which remain outstanding, nor does any such person hold any short positions in relation to Relevant LSE Securities (whether conditional or absolute and whether in the money or otherwise) including any short position under a derivative, any agreement to sell or any delivery obligation or right to require another person to purchase or take delivery, nor does any such person have any arrangement in relation to Relevant LSE Securities. An arrangement also includes any indemnity or option arrangement, any agreement or understanding, formal or informal, of whatever nature, relating to Relevant LSE Securities which may be an inducement to deal or refrain from dealing in such securities.
Due to the need for secrecy, NASDAQ has not made enquiry of certain parties who may be deemed to be acting in concert with it after this announcement of the Final Offers. Appropriate enquiry will then be made and appropriate disclosure (if any) will be made in the Offer Document.
