SCO and Mandrakesoft Achieve LSB Certification

OAKLAND, CA - October 1, 2002 - Continuing the surge of LSB Certified Linux distributions, the Free Standards Group announced that Caldera OpenLinux 3.1.1 from The SCO Group (Nasdaq: SCOX) and Mandrake Linux ProSuite 9.0 from MandrakeSoft have achieved LSB Certification. LSB Certification verifies adherence to the community and industry developed standard for both Linux distributions and Linux-based applications.

"Both Caldera OpenLinux from SCO and Mandrake Linux ProSuite have passed a true milestone, assuring users that these two products meet the highest possible adherence to the LSB standard," said Scott McNeil, Free Standards Group executive director. "That companies continue to apply for LSB Certification demonstrates how important standards are to the continued growth of the Linux market."

LSB, a workgroup under the Free Standards Group, standardizes the core functionality of Linux and the suite of GNU tools, giving Linux distributions and Linux-based applications the opportunity to reach a wider market, while allowing application developers to concentrate on increased functionality. LSB was developed through a collaboration between community developers, Linux distribution companies, ISVs and system vendors.

"This is an important milestone for SCO," said Darl McBride, president and CEO of The SCO Group. "SCO is very dedicated to the development and promotion of standards. We see standards adherence as central to the growth and progression of the Linux industry, and are committed to again being LSB certified when we release SCO Linux, powered by UnitedLinux this fall."

Certification is not a profit center for the Free Standards Group. It was designed to give users and developers the highest confidence that whatever LSB Certified Linux distribution or program they work with meets the highest possible adherence to the standard. Standards for Linux ensure that all LSB Certified applications will work with any LSB certified platform - making deployment on any system, large or small, much easier. Information on certification can be found at www.freestandards.org/certification.

"All through the history of computing, the trend has always been to go towards open standards," said Jacques Le Marois, CEO and Co-Founder of MandrakeSoft S.A. "We strongly believe that the Linux Standard Base is a standard that is going to be massively supported by the computing industry in the near future."

With LSB's full complement of standards, testing and certification, the Free Standards Group has created indispensable tools for Linux.
