HOUSTON, TX (Invensys Process Systems Customer Conference) – October 3, 2005 –Invensys Process Systems today announced it has signed a perpetual license agreement with ExxonMobil Research and Engineering Company to provide its industry leading SimSci-Esscor ( dynamic simulation software, Dynsim, to ExxonMobil's worldwide downstream affiliates. As part of this agreement, Invensys is ExxonMobil’s preferred operator training simulator (OTS) provider. Invensys has also extended its long-term license agreement with ExxonMobil to provide its industry leading SimSci-Esscor process simulation, heat transfer, and flow network modeling software to ExxonMobil affiliates worldwide. Both contracts include software licenses, engineering services, technical support, and training.

These new agreements provide for the standardization of SimSci-Esscor SIM4ME steady state and dynamic process simulation software for new and existing plants and facilities throughout ExxonMobil worldwide affiliate locations. The agreements add the use of Dynsim for dynamic engineering studies, the use of Trisim PLUS for control system checkout of Triconex control logic, and the use of Dynsim software and project implementation services for the development of operator training simulators. The agreements also provide for the continued long-term use of the PRO/II for steady state simulation and design, HEXTRAN for heat exchanger network design and analysis, INPLANT and VISUAL FLOW for fluid flow network and flare system analysis, and PIPEPHASE and NETOPT for multi-phase fluid flow networks analysis and optimization.

"We are pleased that ExxonMobil has extended its relationship with Invensys as a provider of steady state and dynamic process simulation, including heat exchange, and pipeline simulation software within the SIM4ME common modeling environment," said Alastair Fraser, vice president of Invensys’ SimSci-Esscor unit.

“We are also very pleased that ExxonMobil has standardized on SimSci-Esscor solutions for Process Design, Operator Training Simulators (OTS) and Real-Time Optimization (RTO). This will allow ExxonMobil to reap benefits with a consistent modeling framework in the Design, Operate and Optimize phase of a plant’s lifecycle. We have worked closely with ExxonMobil for many years as a technology partner, providing increased value to its worldwide affiliates.
