ASX / MEDIA RELEASE

Medigas Italia SrL Takes Strategic Stake in Compumedics

Melbourne Australia, Wednesday, 30 July 2008

Australia-based medical devices company, Compumedics Limited (ASX: CMP), today announced that Medigas Italia SrL one of its European distributors for diagnostics equipment and the first distributor for its SomniLink® SPAP® sleep-treatment system, has joined Compumedics’ share register with a strategic stake in Compumedics.

Medigas Italia has been a distributor of Compumedics’ sleep-diagnostic equipment in Europe for several years. With the development of Compumedics’ SomniLink® SPAP® sleep-treatment system, Medigas will have a full sleep diagnosis and treatment suite of products.

Medigas Italia is a member of the SIAD group of companies and SIAD is owned 34% by Praxair, Inc, a conglomerate listed on the New York Stock Exchange with USD9.4 billion of sales in 2007, of which 11% were generated from its healthcare division, which includes sleep apnoea treatment products. Medigas Italia is a significant distributor of sleep diagnostics and sleep treatment products in Italy and the former eastern block countries, now including 13 countries where the SIAD group has its operations and facilities outside Italy.

Medigas Italia and Compumedics completed a letter of intent for the distribution of SomniLink® SPAP® systems in June 2007, which was announced to the ASX at that time. Medigas Italia now has a 2.74% holding in Compumedics Limited shares, giving it the third largest shareholding in the company.

Mr Giancarlo Fontana, Sales and Marketing Director of Medigas Italia, said:

“Medigas Italia recognised the potential of Compumedics’ SomniLink® SPAP® system at first glance. The system lifts treatment possibilities for sleep apnoea sufferers to a new level with its inherent capability for improving sleep efficiency. There are no rival products in this field and Medigas is pleased to have access to this new product. Even in normal CPAP operation, the SomniLink® SPAP® will easily be a strong competitor against other current CPAP treatment devices. We are pleased to have commenced a relationship with Compumedics and to have

made this investment in Compumedics to ensure that we will have access to the latest product developments as they occur. We are actively encouraging other members, as well as Medigas Italia, among the companies in the Praxair, Inc Group to take up these products.”

Mr David Burton, Compumedics’ CEO, travelled to Italy in May 2008 to personally deliver the first commercial SomniLink® SPAP® system to Medigas Italia at the annual SIAD-Praxair, Inc Group conference (see attached photograph).

Mr Burton said:

“I am pleased that Medigas Italia has taken this strategic step to directly share in the benefits of the transition of Compumedics from medical devices manufacturer and distributor in the limited sleep diagnostics market to a much larger company offering the next generation of sleep-treatment systems to the significant proportion of the population that suffers from obstructive sleep apnoea.

The relationship with Medigas Italia will provide benefits to both companies beyond the normal distribution arrangements. We are looking forward to working with Medigas Italia and the broader Praxair, Inc Group to realise the potential of our new products in the sleep-treatment market. Compumedics is currently working hard to fulfil the first order of SomniLink® SPAP® systems for delivery to Medigas in the coming few weeks.”
