Dealing disclosure requirements

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 MTL, all "dealings" in any "relevant securities" of MTL
(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 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withdrawn or on which the "offer period" otherwise ends.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 MTL, 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 City Code, all "dealings" in "relevant
securities" of MTL by the offeror or MTL, 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
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.
