Real-Time Systems GmbH Enters Distribution Agreement with Ardence, a Citrix Company

Real-Time Systems GmbH (RTS), a leader in embedded software and
real-time hypervisor technology for Intel architecture-based platforms
announced today that it has been appointed central European
distributor for Ardence embedded products. Ardence, a Citrix company,
(Nasdaq: CTXS) is a leader in embedded software platforms for managed
device control. The newly-added product portfolio perfectly
complements Real-Time Systems' product and service offerings for
real-time and embedded applications.

RTS recently announced the availability of their real-time
hypervisor software product, allowing multiple COTS operating systems
to reside concurrently on a single x86 multicore platform, while
ensuring real-time performance of deployed real-time operating
systems. The staff of RTS has an average of more than ten years of
experience and an extensive know-how in quality embedded software
development, sales and consulting.

"Real-Time Systems GmbH has the technical and engineering capacity
to provide consulting, driver development, image development, and
hardware verification, as well as system debugging. This enables RTS
to work with companies in the device-design phase. That fortunate
positioning creates an opportunity for Ardence. By offering our
solutions, RTS also has additional opportunities for their services,"
said Stephen M. Woodard, Ardence VP and Product Line Executive for
Embedded Products.

Gerd Lammers, Real-Time Systems' CEO said, "Our company is
dedicated to the real-time and embedded market. While our hypervisor
addresses the need of customers to run a mix of different operating
systems in a single application, the Ardence products optimize
Microsoft Windows for its use in real-time and embedded applications,
and greatly complement our own products."

The Ardence product portfolio encompasses RTX(R), ReadyOn(R),
Select(R), and ETS. RTX is the leading solution to provide hard
real-time performance to the Microsoft Windows(R) operating system on
single and multicore architectures. ReadyOn(R) and Select(R) manage
