| ·      | the                write-down of costs in excess of net assets of businesses acquired                (goodwill), as a result of the determination that the acquired business                is                impaired. Our Flex-Kleen reporting unit, which initially performed                well                after being acquired by Met-Pro, thereafter had several years of                declining                performance which we attributed primarily to a general weakness in                its                served markets, followed by improved performance in the fiscal years                ended                January 31, 2006 and 2005. During the fiscal year ended January 31,                2006,                we performed an impairment analysis of the $11.1 million of goodwill                that                the Company carries for Flex-Kleen and concluded that no impairment                had                occurred. Flex-Kleen’s performance needs to continue to improve in order                for us not to be required to write-off some or all of its                goodwill; |
