Concurrent Gets on Board with Lifeboat; Lifeboat Distribution's Sales and Marketing Teams to Further Accelerate Concurrent's NightStar LX(TM) Suite of Real-Time Linux Application Tools to Developers.

DULUTH, Ga. -- Concurrent (NASDAQ:CCUR), a leading provider of time-critical Linux operating systems and tools for mission-critical applications, today announced their NightStar LX suite of real-time Linux application development tools will now be made available to over 6,000 worldwide resellers through Lifeboat Distribution, Inc. (NASDAQ: PROG), an international wholesale provider of software development tools, utilities and other technology benefiting computer software resellers. Through this agreement, Concurrent seeks to provide developers everywhere with the necessary tools to truly harness the processing power of emerging dual and multi-core computing environments.

Concurrent's NightStar is an integrated set of debugging tools especially valuable for developing complex, time-critical Linux applications. Under the terms of the non-exclusive reseller agreement, Lifeboat Distribution will provide sales and marketing support for the NightStar LX tools which are specifically designed to build enhanced, real-time applications on Red Hat(R) Enterprise 4 Linux environments. Over the past 20 years, Lifeboat Distribution has established strong relationships with thousands of resellers who can count on them to supply top software products and outstanding customer service at competitive prices.

"NightStar has long been popular with customers developing time-critical applications on Concurrent Linux and UNIX-based platforms, and we have now expanded the reach of our tools to encompass Red Hat Enterprise 4 environments," said Gary Beerman, Director of Concurrent Marketing. "NightStar LX offers many features that aren't available in the GNU debugger and commercial Linux toolsets, better enabling developers to tackle complicated applications for new multi-core processors."

Time-critical applications require debugging tools that can handle the complexities of multiple processors, multitask interaction and multithreading. Unlike other debuggers, NightStar LX lets you run your program at actual application speeds. NightStar LX also allows you to graphically display application execution and understand how it interacts with itself and with the Linux operating system. The NightStar LX suite includes the NightView(TM) source-level debugger, the NightTrace(TM) event analyzer, the NightProbe(TM) data monitor and the NightTune(TM) system and application tuner.

NightStar LX's advanced features enable system builders to solve difficult problems quickly. The tools are non-intrusive and have minimal impact on an application. The graphics-based tools reduce test time, increase productivity and lower development costs. NightStar tools are especially useful for application development on new Intel(R) and AMD(TM) Dual-Core processor based systems because of their capabilities to debug in a broad variety of multiprocessing environments.

"We're delighted with the opportunity to distribute Concurrent's powerful, advanced application development tools suite to the channel," said Dan Jamieson, Vice President and General Manager, Lifeboat Distribution Services. "Concurrent's real-time development solutions will make a strong addition to the product line card that we offer to our expansive, worldwide network of reseller partners."

NightStar LX is currently available on any Intel P4, Intel Xeon(R) or AMD Opteron(TM) system running Red Hat Linux Enterprise 4. Supported languages include C, C++ and Fortran compiled with either GNU or Intel compilers.
