Montreal, Quebec, April 29, 2003

Génome Québec, a genomics and proteomics investment organization, and CGI Group Inc. (CGI), a leading provider of information technology and business processing services, are working together to provide new solutions that will help reduce costs and speed time-to-market for researchers. As part of the five-year agreement, CGI will create a comprehensive and integrated bioinformatics platform for Génome Québec, based on CGI's bioinformatics and development expertise.

This partnership will allow important jump-start capabilities in bioinformatics for researchers. The ultimate goal of this partnership is to give researchers access to technology solutions that they would not have otherwise therefore reducing significantly research time and costs. Other benefits to researchers include obtaining access to world experts, a commercialization agreement and sharing knowledge.

Génome Québec takes genotyping process to the next level
An important everyday task for geneticists and molecular biologists is that of comparing DNA markers in patients and families, a process called genotyping, a critical technology to identifying genes predisposing to disease. Approaches used to study common complex diseases such as asthma, diabetes and cancer generally have a common requirement for genotyping thousands of markers from all chromosomes, which requires high throughput laboratory processes.

CGI will build, integrate, automate and operate parts of Génome Québec's bioinformatics analysis pipeline, helping increase speed and efficiency across its various genotyping platform technologies. In essence, CGI will build a solution that has the ability to effectively manage genotyping marker information, performance, and history as well as genotyping laboratory activities.

Dr. Tom Hudson, director of the McGill University and Génome Québec Innovation Center highlighted: "A robust platform that can ensure speed and efficiency is what we need. Industrializing our processes translates into quicker-to-market discoveries. It is clearly what will help us propel our science."

CGI establishes Life Sciences Services Center (LS2C) powered by Sun

According to the research company IDC, by the year 2006, US$38 billion will be invested in information technology (IT) in the life sciences sector. To meet the growing demand for new technologies in this market, CGI is investing CDN$4.6 million in the creation of a Life Sciences Services Center (LS2C). The center will be powered by hardware and software contributed by Sun Microsystems, who provides a reliable, secure and scalable infrastructure that helps life sciences companies leverage IT to reduce costs and speed time-to-market.

Paul L'Archevêque, president and CEO of Génome Québec said: "We feel confident in our partner's adherence to strict security controls, something our researchers deem vital. Also of great importance is the fact that the researcher owns their research. The first genotyping project will be integrated into CGI's Life Sciences Center allowing significant and precious productivity gains in the R&D process. We are, simply put, a conduit to effective and efficient discovery processes."

This interactive LS2C provides an integrated portfolio of life sciences solutions and services including public databases and R&D tools for genomics, proteomics, clinical research and laboratory management systems. The center will provide 24x7 technical support and help ensure the highest level of security. The LS2C will maintain computing facilities and storage, integrated solutions and services, access to a secure high capacity telecom network for R&D organizations as well as work coop programs in bioinformatics for PhD candidates.

Michael Roach, president and chief operating officer for CGI added: "We are very excited about our new center as we see many opportunities in the growing healthcare and life sciences sector. We know that we have the breadth and depth that enables us to provide the technology tools that are greatly needed to meet the challenges of advancing science."

CGI employs 600 professionals across North America dedicated to the healthcare and life sciences sectors. During the past decade, CGI has delivered industry-leading solutions to more than five hundred hospitals, health systems and other healthcare providers, as well as health insurers, managed care companies and government payers.
