Dealing Disclosure Requirements

Under the provisions of Rule 8.3 of the Code, if any person is, or becomes, "interested" (directly or indirectly) in one per cent. or more of any class of "relevant securities" of Xploite or Avisen, all "dealings" in any "relevant securities" of that company (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 p.m. (London time) on the Business Day following the date of the relevant transaction. This requirement will continue until the date on which the Scheme becomes Effective, (or, if implemented by way of an offer, the offer becomes, or is declared, unconditional as to acceptances, lapses) or otherwise lapses or is withdrawn or on which the "offer period" otherwise ends. 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 Xploite or Avisen, they will be deemed to be a single person for the purpose of Rule 8.3.

Under the provisions of Rule 8.1 of the Code, all "dealings" in "relevant securities" of Xploite or Avisen by Avisen or Xploite, or by any of their respective "associates", must be disclosed by no later than 12.00 noon (London time) on the 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 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.
