Animas to Acquire Key Cygnus Technology; Acquisition to Help Animas Develop and Broaden Its Next-Generation Glucose Monitoring Product Portfolio

WEST CHESTER, Pa.--()--Dec. 16, 2004--Animas Corporation (NASDAQ NM:PUMP) today announced that it has entered into a definitive agreement with Cygnus, Inc. (OTC BB:CYGN) pursuant to which Animas will acquire substantially all of Cygnus' intellectual property rights, fixed assets, supplier, manufacturing and license agreements, inventory and tangible personal property, for $10 million in cash. Under the terms of the agreement, Animas will take ownership of over 237 U.S. and foreign patents in the fields of continuous glucose sensing, extraction of interstitial fluid by reverse electro-iontophoresis and electrochemical sensors. Animas will not assume any of Cygnus's liabilities in this transaction other than customary obligations under assumed contracts.

"Cygnus has a uniquely strong patent portfolio in the field of glucose sensing," says Dr. Kathy Crothall, President and CEO of Animas. "Cygnus electrochemical sensor technology is quite mature, with Cygnus having produced over ten million electrochemical sensors. The marriage of the micro-needle technology recently licensed from Debiotech to the Cygnus electrochemical sensor technology offers the possibility of a future generation sensor with improved accuracy and less skin irritation than Cygnus' present technology. With this transaction, Animas will add a compelling, minimally-invasive technology to its continuous glucose sensing portfolio. These new technologies nicely complement Animas' long-term implantable sensor development, and when coupled with our superior insulin pump technology, substantially strengthen Animas' position in this important area."

The consummation of the transaction is subject to the approval of Cygnus's stockholders and other customary conditions. Upon consummation of the transaction, Cygnus will cease operations and, at a time to be determined in the future, dissolve under applicable law.
