Palo Alto, California, February 19, 2004 - Imperial Software Technology (IST), the leading provider of mobile financial data solutions, today announced that Aether Systems Limited has licensed IST's DeltaStream Mobile technology to power marketStream, Aether Systems' next generation mobile financial data service.

IST's Deltastream Mobile is a totally wireless market data solution utilizing the latest mobile technology to deliver real-time financial data and trading capabilities to Java enabled mobile devices such as a PDA, phone or RIM BlackBerry.

By utilizing DeltaStream Mobile technology Aether Systems has been able to rapidly deploy marketStream to provide customers with real-time global access to streaming equities, foreign exchange rates, futures, commodities and fixed income prices as well as news and charts via their mobile phone or PDA. marketStream is the successor to Aether Systems' popular financial paging offering, formerly known as miniREUTERS, used by top financial institutions throughout Europe with a peak subscriber base of 15,000 users.

"The successful launch of marketStream is further proof that by adopting Deltastream Mobile, companies and institutions looking to provide mobile financial data to customers and employees can do so without the large investment inherent in developing their own system from the ground up" commented Derek Lambert, Managing Director of Imperial Software Technology. "Deltastream Mobile is a proven, cost effective solution that removes the barrier to entry into the wireless financial data market."

"Aether Systems selected IST as its partner for the marketStream product because IST's DeltaStream technology was superior to anything else we'd seen, and because of IST's excellent track record in software engineering" said Morten Nielsen, Managing Director of Aether Systems Limited. "Above all, we selected IST because they have a great team to work with."

A highly scaleable and secure mobile financial data delivery platform, DeltaStream Mobile encompasses both server side and client device technology and is fully customizable to support service provider requirements and data feed preferences.

DeltaStream Mobile provides feature rich, user configurable data visualization on the mobile device including live streaming data showing the price changes of stocks and indices, charting, statistics and news articles. Advanced technology is used to ensure low bandwidth over General Packet Radio Service (GPRS) and 3G networks with no compromise on performance thereby ensuring low overheads, a key requirement for both data provider and mobile device owner.

Device support includes a wide range of Personal Java or MIDP Java enabled mobile devices including Pocket PC devices (such as Compaq iPaq), RIM BlackBerry, PalmOS devices (such as Handspring Treo) and phones from suppliers such as Nokia and Sony Ericsson.

The Aether marketStream launch follows on from the recent launch of MoneyAM Mobile, another successful wireless financial data service based on IST's DeltaStream Mobile solution.
