Millipore Cidra stated that membrane scrap from its production of nitrocellulose-based membrane is not a hazardous waste. The Company believes that good science should prevail in this matter and expects to achieve timely and favorable resolution of this issue. After the close of business Friday, May 2, the EQB served an administrative order alleging that membrane scrap discarded during the production of Millipore Cidra's nitrocellulose-based membrane is a hazardous waste. The EQB proposes a fine of $96.5 million against Millipore Cidra, Inc. However, the Company's experience in manufacturing and handling the membrane scrap, supported by analytical tests performed in accordance with applicable U.S. Environmental Protection Agency and EQB regulations show that such waste is not a hazardous waste under such regulations. Millipore Cidra, Inc., based in Cidra, Puerto Rico, employs 310 persons and has operated in Puerto Rico for twenty years. Millipore Corporation, its parent company, has an established health, safety and environmental policy which has been adopted by Millipore Cidra, Inc. Millipore Cidra's nitrocellulose-based membrane is a specialized filter used across a wide range of research and commercial applications. Examples of such uses include the filtering of fluids used in the production of pharmaceutical products, water testing and quality control processes for consumer beverages. Millipore produces over 50 filtration materials, in addition to the nitrocellulose-based membrane. Millipore is a multinational high technology company that applies its purification technology to critical research and manufacturing problems in the microelectronics, biopharmaceutical and analytical laboratory markets. The matters discussed herein are forward-looking statements and are based on current management expectations that involve substantial risks and uncertainties (including the uncertainties of litigation) which could cause actual outcomes to differ materially from those expressed in, or implied by, these forward- looking statements. Potential risks and uncertainties that could affect the Company's future operating results include, without limitation, foreign exchange rates; increased regulatory concerns on the part of the biopharmaceutical industry; further consolidation of drug manufacturers; competitive factors such as new membrane technology, and/or a new method of chip manufacture which relies less heavily on purified chemicals and gases; availability of component products on a timely basis; inventory risks due to shifts in market demand; change in product mix; conditions in the economy in general and in the microelectronics manufacturing market in particular; the difficulty in integrating acquired companies; potential environmental liabilities; the inability to utilize technology in current or planned products due to overriding rights by third parties, and the risk factors listed from time to time in the Company's filings with the SEC.
