Raleigh, NC, April 25, 2000 -- CLOSURE Medical Corporation (Nasdaq: CLSR), a medical tissue cohesive products company, today announced that total revenues for the three months ended March 31, 2000 were $2,666,000 compared to $3,817,000 in the 1999 corresponding period. The net loss for the 2000 quarter was $618,000, or ($.05) per basic and diluted common share, compared to a net loss of $565,000, or ($.04) per basic and diluted common share in the corresponding 1999 period.

Cash and cash equivalents and total investments were $11.5 million at March 31, 2000 compared to $12.6 million at December 31, 1999.

During the quarter the Company initiated a clinical study for LIQUIDERM™ liquid adhesive bandage for the treatment of minor cuts and abrasions. Results from the study will be used in an anticipated 510(k) submission to the FDA later this year. In February, the Japanese Ministry of Health and Welfare cleared DERMABOND® Topical Skin Adhesive for marketing in Japan—a wound closure market of approximately $500 million and growing 9% per year, according to Global Industry Analysts, Inc.

“We are encouraged by our advancements on many fronts,” said Robert V. Toni, President and Chief Executive Officer. “The clinical trials for LIQUIDERM™ are moving ahead of schedule, and Ethicon Inc., our marketing partner, is progressing in its efforts to penetrate the operating room marketplace for DERMABOND®. We continue to develop line extensions—alternatives to the current delivery system and viscosity -- to complement this effort, while we continue to make significant progress on several potential new products.”

CLOSURE Medical Corporation, headquartered in Raleigh, North Carolina, develops, manufactures and commercializes medical tissue adhesive products based on its proprietary cyanoacrylate technology.
