"Our business mix and operating methods allow us to gain profitable market share and deliver solid results. The strength of our long-cycle business such as master service agreements combined with our on-going initiatives -- branding, value added service offering and focus on operating efficiencies -- give us confidence that 2001 will be another year of strong earnings performance."
