Catuna Owen Daley (media) Vice President, Finance Allen & Caron, Inc Isonics Corporation (714) 252-8440 (408) 260-0155 ISONICS CORPORATION COMPLETES CHEMOTRADE GMBH ACQUISITION SAN JOSE, CA (July 21, 1998) . . . Isonics Corporation (OTC: ISON) reported today that it completed its previously announced acquisition of Dusseldorf, Germany-based Chemotrade GmbH for $2.5 million in a combination of cash, notes, and restricted Isonics common stock. Additional consideration of $1.1 million is payable over the next three years based on Chemotrade meeting future profitability targets. Chemotrade, a supplier of both stable and radioactive isotopes to customers world-wide, had sales of over $7 million for its fiscal year ended December 31, 1997 and has been profitable in each of the past 7 years. The Company will operate as a wholly owned subsidiary of Isonics with existing management remaining in place. Isonics President & CEO James E. Alexander commented, "The acquisition of Chemotrade not only opens the European market and provides access to key customers for Isonics products, it also expands our product lines to include radioisotopes used in medical diagnostics and therapeutics. Our goal is to leverage Chemotrade's current European market position while implementing plans to bring our stable isotope production capabilities to western Europe." Isonics is a specialty chemical and advanced materials company, which develops and commercializes products based on enriched stable isotopes. Stable isotopes can be thought of as ultra-ultra pure materials. This high degree of purification provides enhanced performance properties compared to normal materials. Stable isotopes have commercial uses in several areas, including energy; research, medical diagnostics, and drug development; product tagging and stewardship; semiconductors; lasers; and optical materials.
