These written materials are not an offer of securities for sale in the United
States. Securities may not be offered or sold in the United States absent

Unless otherwise determined by BowLeven and subject to any dispensation required

without limitation, telephonically or electronically) of interstate or foreign
commerce of, or through any facilities of a national securities exchange of, the
United States, Canada, Australia or Japan or any other jurisdiction if to do so
would constitute a violation of the relevant laws of such jurisdiction, and the
Offer, when made, should not be accepted by any such use, means, instrumentality
or facilities or from or within the United States, Canada, Australia or Japan or

the Offer to be completed if, in its sole discretion, it is satisfied that the
transaction in question can be undertaken in compliance with applicable law and
regulation.


Dealing Disclosure Requirements

Under the provisions of Rule 8.3 of the Code, if any person is, or becomes,
'interested' (directly or indirectly) in 1% or more of any class of 'relevant
securities' of BowLeven or of FirstAfrica, 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 pm (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acceptances, lapses or is otherwise withdrawn or on which the 'offer period'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 BowLeven or of FirstAfrica, 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 BowLeven or of FirstAfrica or 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.
