year.

FSG, with approximately $270 million in sales, is a pioneer in the design,
manufacture and sale of filtration products for the separation and purification
of liquids and gases. Five divisions comprise FSG, including Filterite and Fluid
Dynamics, located in the United States, Schumacher and SeitzSchenk Filtersystems
in Germany and Exekia in France. The companies primarily serve the food &
beverage, industrial, microelectronics, biotech and pharmaceutical industries.

"We are combining very successful leaders of our industry with complementary
strengths," continued Krasnoff. "The result is an even better enterprise poised
for sustainable growth and continued leadership. For customers this means the
ease and reliability that comes with partnering with one supplier for integrated
solutions for all their filtration and separations needs."
