Aurel Systems Signs Corporate-Wide Agreement with Tembec. CADSIM Plus Process Simulation Software to be deployed in all Tembec Mills

VANCOUVER, May 27, 2002 -- Aurel Systems Inc. today announced that it has signed a three-year, corporate-wide lease agreement with Tembec Inc. to place its CADSIM Plus dynamic process simulation software in all 14 of Tembec's pulp and paper mills, and in Tembec's Corporate Office in Temiscaming, QC. Under the agreement, Aurel will provide the CADSIM Plus software, plus an annual allotment of training and engineering consulting time, to be used at the discretion of Tembec.

Tembec is a leading integrated Canadian forest products company principally involved in the production of wood products, market pulp and papers. With annual sales over $3 billion dollars, Tembec operates more than 50 manufacturing units in Canada, France, and the United States. These include the mills where CADSIM Plus is to be deployed: Marathon Pulp, Skookumchuck, Smooth Rock Falls, Tembec Saint-Gaudens, Tembec Tarascon, Tembec Matane, Temcell, AV Cell, Specialty Cellulose, Tembec Tartas, Pine Falls, St. Francisville, Saint-Raymond, and Spruce Falls. Tembec employs approximately 10,000 people.

"Tembec has a mandate to develop vendor partnerships which consistently meet our quality, service and price requirements," said Mark Champagne, Process Optimization Manager for Tembec. "Our successful field evaluations of the CADSIM Plus process simulator have satisfied us that Aurel's software and services are a valuable asset that will assist us in meeting our objectives of continuous improvement of processes and product quality and energy efficiency, while honouring our commitment to environmental responsibility. We look forward to partnering with Aurel in the development of new applications, in which CADSIM Plus will be linked to our mill control and information systems, to provide control and operational enhancements."

"CADSIM Plus offers Tembec extensive dynamic process modeling capabilities that are easy to use, comprehensive, and cost effective," said Larry S. Wasik, President of Aurel Systems Inc. "Tembec has the reputation of being a progressive company that uses new technologies to great advantage. We are very excited about partnering with Tembec in the continued development of state of the art tools for engineering design, problem evaluation, case study, and operator training and assistance.
