SO. ST. PAUL, MN – February 20, 2007 – Digital Angel Corporation (AMEX: DOC – News) has signed a multi-year exclusive distribution agreement with Schering-Plough Home Again LLC (NYSE: SGP – News), a wholly owned subsidiary of Schering-Plough Corporation, to provide electronic identification microchips and scanners as part of the HomeAgain™ Proactive Pet Recovery Network, Digital Angel announced today. Schering Plough’s new network, which markets the complete Digital Angel electronic pet identification system under the brand name HomeAgain™, is the nation’s first comprehensive system to assist in the search for lost pets.

“The need to identify and track companion animals is profound particularly after a major event such as Hurricane Katrina,” said Kevin McGrath, CEO and President of Digital Angel. “One in three pets becomes lost during his or her lifetime and without proper identification 90 percent never return home. This indicates a significant need for a microchip-based proactive recovery service. This renewed partnership with Schering-Plough, using our patented radio frequency identification (RFID) implantable microchips, will help us continue to serve pet owners and the expanding pet health product market in the United States.”

The new agreement with Schering-Plough replaces a contract signed in 2004. The agreement is necessitated by significant and positive changes in the Schering-Plough business model for the HomeAgain system. Currently, more than 100 million pets in the United States are not micro-chipped or enrolled in a recovery service.

McGrath commented, "We anticipate a significant increase in the number of pets micro-chipped as Schering-Plough launches its new HomeAgain business model. Through May 2007, Schering-Plough has already committed to purchase more microchips than it purchased in all of 2006. We believe 2007 microchip unit sales to Schering-Plough will be significantly above last year’s sales.”

Digital Angel has been a pioneer in pet identification. The company has developed and manufactured a series of RFID products for pets including microchips, readers and non-surgical injection systems for 15 years.

Schering-Plough launched the new HomeAgain network in January. The advanced pet-tracking system begins with an implantable microchip, a safe and permanent form of identification. When a registered pet is found and scanned, the pet can be traced back to his or her owner through the national database. Additionally, within minutes of a missing pet report being filed with a 24-hour, seven day-a-week emergency call center, dispatchers notify area shelters and veterinary clinics and share information such as the pet's description and a photo. More than 4 million pets in the United States have been implanted with a HomeAgain microchip, resulting in more than 300,000 successful recoveries.

Digital Angel is a leader in implantable RFID microchips for livestock, equine, fish and pets. The advanced technology company also manufactures aircraft and personal locator tracking beacons for many of the world’s top military forces.
