March 31, 2004, Salem, New Hampshire: ioMosaic Corporation President Dr. Georges A. Melhem announced today that Tyco and ioMosaic have executed a Memorandum of Understanding (MOU) to develop the industry's first solution for design-to-procurement of pressure relief devices™.

Under the terms of the MOU, software development teams from Tyco and ioMosaic will integrate ioMosaic's leading emergency relief system (ERS) design and workflow automation solutions, SuperChems and ioXpress, with Tyco's product data. Operating companies and engineering firms would be able to design a pressure relief device and rely on the integrated solution's intelligence to select the most appropriate device based on key parameters such as set point, relieving rate, service / relieving conditions, backpressure considerations, etc. This data would then be seamlessly transmitted to the relevant enterprise resource planning (ERP) or procurement system for either order placement or generating vendor inquiries for competitive sourcing.

“Design-to-procurement is a truly remarkable concept that can help operating companies and engineering firms realize tremendous efficiencies”, said Mr. Chris Buxton, Applications and Technology Manager at Tyco. He further added “ioMosaic's industry leadership in pressure relief system design methodologies and solutions makes them an obvious choice as a technology partner to help realize this vision.”

Dr. Melhem adds, “Tyco has for years maintained an undisputed leadership in pressure relief valve design and research as is evidenced by the breadth of their brands, products, and global client base. As we developed the Design-to-Procurement of Pressure Relief Devices vision in our organization, we wanted to align ourselves with the most innovative and resourceful manufacturer – and clearly that was Tyco.”

Tyco and ioMosaic expect to launch a pilot program at a major operating company in the near future.
