SensaTank RV 100 Featured on New Fleetwood American Coach Lines

ELK GROVE VILLAGE, Ill.--June 3, 2004--Material Sciences Corporation's Electronic Materials and Devices Group, Inc. (EMD) today announced the inclusion of its unique SensaTank(TM) RV 100 holding tank monitoring system on the new Fleetwood American Coach Lines for the 2005 model year -- which includes the Eagle, Tradition and Revolution Models. This is an expansion of MSC-EMD and Fleetwood's existing relationship. Last year, the SensaTank RV 100 was incorporated on Fleetwood's high-end Monoplexed Heritage "Victory Circle" Coach.

The SensaTank(TM) RV 100 is a solid-state, digital monitoring system that utilizes proprietary Mirus(TM) detector cells to measure fluid levels in grey, fresh and black water holding tanks. These detector cells are free of moving parts and mount externally on the plastic holding tanks -- which eliminates the reliability issues that are inherent with traditional probe solutions.

The digital nature of the Mirus(TM) detector cells also gives Fleetwood the capability to link the SensaTank(TM) monitoring system directly into their proprietary monoplex data system, which allows for all of the vehicle's electronic units to be incorporated into a common communication circuit.

"It's another step in MSC-EMD's effort to establish the SensaTank RV 100 as the standard for holding tank monitoring systems," said Gregg Pardus, Director of Business Development for MSC-EMD.
