Disclosure requirements of the Irish Takeover Rules
Under Rule 8.3(b) of the Irish Takeover Rules, any person 'interested' (directly or indirectly) in 1% or more of any class of 'relevant securities' of Kenmare must disclose all 'dealings' in such 'relevant securities' during the 'offer period'. The disclosure of a 'dealing' in 'relevant securities' by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 pm (Irish/UK time) on the business day following the date of the transaction. A dealing disclosure must contain the details specified in Rule 8.6(b) of the Irish Takeover Rules, including details of the dealing concerned and of the person's interests and short positions in any 'relevant securities' of Kenmare.

If two or more persons co-operate on the basis of an agreement, either express or tacit, either oral or written, to acquire for one or more of them an interest in relevant securities, they will be deemed to be a single person for these purposes.

Disclosure tables, giving details of the companies in whose 'relevant securities' 'opening positions' and 'dealings' should be disclosed, can be found on the Takeover Panel's website at .

'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.
