style='font-size:10.0pt;font-family:Arial'>Membranes provide efficient removal
of very small particles.  Non-woven cartridges are the second largest
segment.  Carbon cartridges are growing in popularity due to their ability
to adsorb contaminants and compounds that affect taste. String wound cartridges
are used for separating in production processes in the chemical and paint
manufacturing industries.  Metal cartridges are used when high
temperatures are encountered. An example of this type of application is polymer
filtration.

growth in flat panel display production, steady expansion of the biotechnology
industry, Asian investment in chemicals and petrochemicals, and the commitment
to new coal-fired plants in China and the U.S. are growth sectors for cartridge
suppliers.

largest cartridge purchaser by 2008. Assuming India continues on its present
high growth path, it will be the tenth largest purchaser by 2008. The top ten
