Overseas shareholders

The availability of the Offer to Allied Gold Shareholders who are not
resident in the United Kingdom, Australia or the United States or not
located in Canada may be affected by the laws of the relevant
jurisdictions in which they are located or of which they are resident.

The release, publication or distribution of this announcement in
certain jurisdictions may be restricted by law. Persons who are not
resident in the United Kingdom, Australia or the United States or not
located in Canada or who are subject to other jurisdictions should
inform themselves of, and observe, any applicable requirements of their
jurisdictions. Any failure to comply with the applicable restrictions
may constitute a violation of the securities laws of any such
jurisdiction. To the fullest extent permitted by applicable law, the
companies involved in the Offer disclaim any responsibility or
liability for the violation of such restrictions by any person.

Further details in relation to overseas Allied Gold Shareholders are
contained in the Scheme Document.

The Offer relates to the shares in an English company and is proposed
to be made by means of a scheme of arrangement provided for under
company law of the United Kingdom. The scheme of arrangement will
relate to the shares of a UK company that is (a) a 'foreign private
issuer' as defined under Rule 3b-4 under the Securities Exchange Act of
1934, as amended (the "Exchange Act") and (b) a "designated foreign
issuer" under applicable Canadian securities laws. A transaction
effected by means of a scheme of arrangement is not subject to the
shareholder vote, proxy and tender offer rules under Australian law,
Canadian securities law or the Exchange Act. Accordingly, the Offer is
subject to the disclosure requirements and practices applicable in the
UK to schemes of arrangement, which differ from the disclosure
requirements and practices of Australian, Canadian or US shareholder
vote, proxy and tender offer rules. Financial information included in
the relevant documentation will have been prepared in accordance with
accounting standards applicable in the UK that may not be comparable to
the financial statements of Australian, Canadian or US companies.

No securities regulatory authority in any Canadian jurisdiction has (a)
approved or disapproved of the Offer; (b) passed upon the merits or
fairness of the Offer; or (c) passed upon the adequacy or accuracy of
the disclosure in this announcement. Any representation to the contrary
is an offence in Canada.

Any securities to be offered pursuant to the Offer as described in this
announcement have not been and will not be registered under the US
Securities Act of 1933, as amended (the "Securities Act"), or under the
securities laws of any state, district or other jurisdiction of the
United States, or of Canada, Australia or Japan. Accordingly, such
securities may not be offered, sold or delivered, directly or
indirectly, in or into such jurisdictions except pursuant to exemptions
from applicable requirements of such jurisdictions. The St Barbara
Shares to be issued in exchange for Scheme Shares pursuant to the
Scheme will be issued in reliance upon exemptions from the prospectus
requirements of securities legislation in each province and territory
of Canada. Subject to certain disclosure and regulatory requirements
and to customary restrictions applicable to distributions of shares
that constitute "control distributions", St Barbara Shares issued
pursuant to the Scheme may be resold in each province and territory in
Canada, however the first trade in such St Barbara Shares will be
subject to the standard conditions that no unusual effort has been made
to prepare the market or create demand, no extraordinary commission or
consideration is paid and, if the selling shareholder is an insider or
officer of St Barbara, such shareholder has no reasonable grounds to
believe that St Barbara is in default of securities legislation.

Copies of this announcement and formal documentation relating to the
Offer will not be and must not be, mailed or otherwise forwarded,
distributed or sent in, into or from any jurisdiction where to do so
would violate the laws of that jurisdiction.
