established provider of digital data collection services. Subject only to
receipt of the consideration monies by the vendors of Common Knowledge, which
is expected to occur later today, ToLuna has agreed to acquire the entire
issued share capital of Common Knowledge for an initial cash consideration of
US$8.49 million. In addition, deferred consideration of US$2.16 million is
payable in cash, of which the first payment of US$1.255 million is payable on
18 June 2009, with the second payment of US$0.905 million being payable on 18

existing cash resources, a new multicurrency revolving loan facility of £3
million and additional funding of £512,500 raised from an issue of new ordinary
shares to Eurovestech plc ("Eurovestech") at a price of 205p per share, the
