Sierra Systems to Acquire Calgary-based RIS

Sierra Systems Group Inc., a leading information technology and management consulting services company, announced today that it will acquire privately-held RIS, Inc. - a top provider of applications support and maintenance services (ASM).

RIS supports, maintains and enhances critical computer applications for some of North America's largest companies. Founded in 1979, the Calgary-based company's portfolio of ASM-specific services range from IT staffing to full application outsourcing.

RIS' expertise in the managed service provider market, particularly in the areas of ASM and staff augmentation, will enable Sierra Systems to provide private and public sector customers across North America with a full range of IT services - from management consulting and project implementation, to support and maintenance of those solutions over time. The acquisition will also provide Sierra Systems with an enhanced presence across Canada - especially in Calgary and Toronto but also in other areas where RIS has a presence including Regina and Edmonton, as well as Bucharest, Romania and the United States.

"RIS brings thought and market-leadership in the managed service provider space, as well as a strong service delivery track record in enterprise resource planning, business intelligence and data warehousing," explains Joe Campbell, Sierra Systems' President and CEO. "Together with Sierra Systems' expertise in delivering large projects, linking strategy with results and offering a flexible delivery model, we will be able to build upon our exceptional customer satisfaction levels and enhance our service offering to our clients."

"Today's announcement opens an exciting new chapter in a story that began more than a quarter-century ago," says RIS President, CEO and Founder Dr. Peter Thompson. "It's a natural extension of our vision for applications support and maintenance, and our strategy for leadership in niche IT services. For our clients and our team - many of whom have been with us from day one - it means even greater resources, services and opportunities."

Golden Gate Capital, the San Francisco-based private equity investment firm that took Sierra Systems private earlier this year, supported Sierra in the acquisition. According to Golden Gate Capital Managing Director David Dominik, "We look for information technology services companies with world-class cultures and sustained track records of delivering superior results for their clients. Sierra and RIS have both. The opportunities created by combining these two organizations with very complementary services offerings, vertical expertise, and geographical presence will position the combined company to achieve the next stage in its growth."

The acquisition is expected to close on November 30, 2007. Effective January 1, 2008, RIS' operations and its over 250 employees and 350 subcontractors will operate under the Sierra Systems' name.
