(NASDAQ: PESI) (GERMANY: PES.BE) and its CEO, Dr. Louis F. Centofanti announced today that it has completed the previously announced acquisition of Chemical Conservation Corporation, Chemical Conservation of Georgia, Inc. and Chem-Met Services, Inc. collectively referred to as "Chem-Con." The combined purchase price of this acquisition totaled $8.7 million, with the consideration paid in the form of cash, notes and common stock. Chem-Con has more than 30 years of experience and proven expertise in the waste industry and operates waste treatment facilities in Orlando, Florida; Valdosta, Georgia; and Detroit, Michigan. For the year ended September 30, 1998, Chem-Con had combined revenues of approximately $22 million and net income of $480,000. The acquisition of Chem-Con is of strategic importance to the continued growth of Perma-Fix and, including Chem-Con revenues for a full twelve months, will result in revenue growth to an annualized run-rate of more than approximately $55 million. In addition, the acquisition significantly expands the Company's presence into several new major markets and geographic locations. Perma-Fix currently operates waste treatment facilities in Gainesville, Florida; Ft. Lauderdale, Florida; Dayton, Ohio; and Tulsa, Oklahoma. Chem-Con's revenues are principally generated from the collection, treatment, and recycling of industrial and hazardous waste, including waste oils, water and miscellaneous solid waste. Chemical Conservation Corporation operates a permitted treatment and storage facility and transfer station that also serves as the base for a private trucking fleet; Chemical Conservation of Georgia, Inc. treats hazardous waste and recycles solvents; and Chem-Met Services, Inc. treats and stabilizes inorganic wastes and maintains a government services division that is focused principally on the Defense Revitalization and Marketing Services (DRMS) market. Perma-Fix will utilize this established government services division as a platform to further enhance its current and future governmental initiatives. Perma-Fix will immediately capitalize on new growth opportunities by incorporating the use of its proprietary Perma- Fix I and patent-pending Perma-Fix II processes at these facilities. -MORE- Page 2 June 3, 1999 Commenting on the acquisition, Dr. Louis Centofanti, Chairman and Chief Executive Officer commented, "The acquisition significantly expands the size of our market, increases our geographic presence and represents a strategic milestone in the growth of our Company.
