To: Icebrg who wrote (3296 ) 10/1/2002 8:47:44 AM From: Icebrg Respond to of 10345 Acusphere and Elan Terminate Joint Venture All Intellectual Property and Development Rights Assigned to Acusphere Tuesday October 1, 8:37 am ET WATERTOWN, Mass.--(BUSINESS WIRE)--Oct. 1, 2002--Acusphere, Inc. announced today that it has reached an agreement with Elan Corporation, plc (NYSE:ELN - News) and affiliates, terminating, in a cash-free transaction, their joint venture established in June 2000. This joint venture was formed to develop and commercialize certain pulmonary drug delivery product candidates. The termination of the joint venture is a result of Elan's restructuring efforts and desire to focus on its core businesses in neurology, pain and autoimmune diseases. Under the termination agreement, Acusphere was assigned all intellectual property and development rights to product candidates developed by the joint venture. In exchange for this assignment, Acusphere has agreed to pay Elan a royalty on certain revenues that may be realized by Acusphere in the future on these product candidates. "From the beginning of our joint venture with Elan, we had an extremely productive relationship," said Sherri C. Oberg, Acusphere's President and CEO. "This is demonstrated by the rapid development of our sustained release asthma drug candidate, AI-SR(TM), which entered the clinic in May 2002. The assignment of all joint venture product rights to Acusphere in a cash-free transaction allows us to move ahead and control all decision-making going forward, with respect to future product development and strategic partnering on these products."
