[GRAPHIC OMITTED] PRESS RELEASE FOR IMMEDIATE RELEASE AETERNA'S SUBSIDIARY ATRIUM MAKES A SECOND ACQUISITION IN FRANCE QUEBEC CITY, QUEBEC, MAY 1, 2002 - Luc Dupont, Vice Chairman of the Board and Chief Executive Officer of Atrium Biotechnologies Inc., a subsidiary of AEterna Laboratories Inc. (TSE: AEL, NASDAQ: AELA), today announced the acquisition of the privately-owned French company ADF Chimie S/A, (ADF), at a cost of $3 million and also acquired a line of nutritional supplements for the sum of $500,000. All amounts are expressed in Canadian dollars. ADF first opened its doors 15 years ago in Poitiers, France, and is a distributor of active and specialty ingredients for the French cosmetics industry. Last year, its sales to some 50 clients, including L'Oreal, LVMH and Chanel, reached more than $5 million. This is Atrium's second French acquisition in less than a year. Last July, in a $20-million transaction, Atrium acquired 70% of Unipex, an important French company that specializes in the value-added distribution of raw materials in the sectors of nutrition, fine chemicals, cosmetics and pharmaceuticals. "Adding these new specialized products to Unipex's list, enhances its offer and strengthens client relations in the active ingredients sector," declared Luc Dupont, Vice Chairman of the Board and Chief Executive Officer of Atrium Biotechnologies. "Furthermore, this transaction enables us to acquire competence in hair colorants, dispersants and active vectors, giving us access to a new clientele that will allow us to develop new markets," added Mr. Dupont. For an additional sum of $500,000 Atrium also acquired a line of nutritional supplements including six products with sales in excess of $1 million in 2001. Optimizing distribution of these products will be facilitated through Atrium's network which presently stretches to some 20 countries around the world. "The current demand for these cosmetic and nutrition products is quite strong, and will enable us to extend our range of products and support additional growth in this segment of our operations," said Mr. Dupont. "These acquisitions are a perfect fit to our growth strategy of making Atrium the most important Canadian developer and distributor of high-end raw materials, value-added products and active ingredients in the fields of cosmetics, nutrition, fine chemicals and pharmaceuticals."
