Compuware Enhances Device Driver Development Suite for Microsoft Windows Operating Systems

DriverStudio 2.0 Delivers New Tools for Developing Network Drivers; Provides Extensive Support for Microsoft Windows Millennium Edition

FARMINGTON HILLS, Mich. -- September 12, 2000 -- Compuware Corporation (NASDAQ:CPWR) today announced powerful new features included in NuMega DriverStudio 2.0, which will be available at the beginning of October. DriverStudio, the industry's leading suite of device driver development tools for all Windows desktop platforms including Windows 2000 and Windows Millennium Edition, provides developers with high quality tools that accelerate device driver development, debugging, tuning, testing and deployment.

"Whether I'm developing drivers, debugging drivers, writing WDM drivers or creating VxDs, I can find the tools that help me most in Compuware's DriverStudio," said Tim Adams, VP of Engineering at SpectorSoft Corporation, makers of Spector Internet monitoring software.

DriverStudio helps developers deliver high quality Windows device drivers by removing the complexity and guesswork normally required in coding, debugging, tuning and testing. DriverStudio is the only product available that addresses the device driver development process from development through deployment. Each DriverStudio tool fits a unique need and, when integrated into the development process, helps developers solve the most difficult device driver development problems.

DriverStudio 2.0 extends its analysis, development and debugging capabilities to include network driver development and debugging, enabling driver developers to create and debug robust NDIS and TDI drivers. DriverStudio 2.0 also delivers comprehensive debugging support for the Windows Millennium Edition, with new versions of BoundsChecker Driver Edition and DriverWorkbench as well as with enhanced features in SoftICE.

"Our prime concerns are the solid, working capabilities of our drivers at customer sites. With the help of Compuware's DriverStudio, we are confident that latent bugs are identified and addressed prior to shipment," said Chris White, Software Development Manager at FastPoint Technologies, Inc., a manufacturer of light pens.

One of the most innovative features introduced in DriverStudio 2.0 is timing analysis for kernel mode drivers. TrueTime Driver Edition improves the testing process by providing a visual display of code timing information that allows developers to precisely determine where code bottlenecks exist. Consequently, developers using TrueTime Driver Edition can deliver more reliable, better performing device driver software.

"DriverStudio continues to make a significant impact on the market for Windows kernel-mode development tools," said Doug Turner, Vice President of Product Management at Compuware Corporation. "DriverStudio 2.0 provides device driver developers with the tools and technologies they need for building complex drivers on tight deadlines."

Pricing and Availability

The DriverStudio 2.0 U.S. list price is $2,499 and will be available in the beginning of October. Developers who purchase DriverStudio 1.5 today will receive DriverStudio 2.0 as a part of their subscription price. The DriverStudio annual subscription provides timely product updates and unlimited technical support.
