FOR IMMEDIATE RELEASE Jim O'Shea Noonan/Russo Communications, Inc. Chairman, President, & CEO 212-696-4455 Sam Nickerson Kristen Hammer (media) 249 Investor Relations Belinda Brouder-Hayes (investor) 224 Bioject Medical Technologies Inc. Email: news@noonanrusso.com 503-639-7221 BIOJECT REPORTS SALE OF ITS GLUCOTRAXTM TECHNOLOGY -Company will focus on core needle-free business- PORTLAND, OR - July 2, 1999 - Bioject Medical Technologies Inc. (Nasdaq: BJCT), the leading manufacturer of jet injection technology for needle-free drug delivery today announced that Marathon Medical Technologies Inc., Bioject's joint venture with Elan Corporation, plc (NYSE: ELN), has entered into an agreement to sell the venture's license and other rights to the GlucoTrax(TM) blood glucose monitoring technology to Medisys, plc. (AIM: MDY.L). Medisys is a U.K.-based medical device company which has developed and commercialized devices to monitor blood glucose levels. In accordance with the terms of the agreement, Bioject and Elan will receive $4 million for the sale of the license and related intellectual property rights and certain fixed assets of the joint venture. Bioject had an 80.1 percent ownership stake in the joint venture and estimates the receipt of approximately $2.5 million in net cash proceeds. In addition, Marathon will receive royalties on future revenues, if any, generated by the GlucoTrax technology. "Choosing to sell the blood glucose monitoring technology was difficult," said Jim O'Shea, Bioject's chairman, president and CEO. "While we would have liked to continue to develop GlucoTrax, pursuing simultaneous development of both the blood glucose monitor and our next-generation needle-free injection systems placed an excessive burden on our capital resources. Selling the technology significantly reduces the company's current cash requirements and generates additional cash reserves to support the core needle-free side of our business." Commenting on Bioject's near-term strategy, Mr. O'Shea added, " We are very excited about the opportunities available to Bioject. There is growing interest in Bioject's needle-free injection technology as a potentially enabling drug delivery method, as evidenced by the use of the Biojector(R) 2000 in recent human clinical studies at Stanford University and at the U.S. Naval Medical Research Center. We will continue to develop the needle-free business through the establishment of corporate alliances to capitalize on market opportunities and enhance our commercial presence." -more- Bioject Medical Technologies, Inc. located in Portland, Oregon is an innovative developer and manufacturer of drug delivery systems.
