Sondex plc announces the acquisition of Ultima Labs Inc ("Ultima Labs"), a
private Houston based technology development company with a range of IP and

the oilfield service industry, for a consideration of up to US$9.225 million

Ultima Labs is a technology development company based in Houston, USA. The
primary product that has been developed and is in the process of being

development for both wireline and drilling applications will remain with the
business and participate in the integration of the technology and development of
future product lines.
