                          Alexon Group plc ("Alexon")

Pursuant to Rule 2.10 of the Takeover Code, Alexon announces that it has

Dealing Disclosure Requirements

Under the provisions of Rule 8.3 of the Takeover Code (the "Code"), if any
person is, or becomes, "interested" (directly or indirectly) in 1% or more of
any class of "relevant securities" of Alexon, 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 3:30pm (London time) on the London business day
following the date of the relevant transaction. This requirement will continue
until the date on which the offer becomes, or is declared, unconditional as to
acceptances, lapses or is otherwise withdrawn or on which the "offer period"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 Alexon, 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 Alexon by a potential offeror or by Alexon, 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 Code, which can also be found on the
Takeover 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 Takeover
Panel.
