The Board of Baltimore notes with interest earthport plc's announcement of a
possible offer to acquire Baltimore. The Board has not had any approach from
earthport plc nor does it have any details of a proposed offer but if and when
it does it will consider this matter with its professional advisers and respond
as appropriate. Baltimore will continue to vigorously defend the claim brought
against it by earthport plc and will tomorrow be seeking an order from the High
Court that earthport plc provides further information previously requested
regarding its claim.
