MELVILLE, N.Y. – July 19, 2006 – Henry Schein, Inc.(NASDAQ: HSIC), the largest provider of healthcare products and services to office-based practitioners in the combined North American and European markets, today announced an exclusive distribution agreement with Imaging Sciences International, Inc., a market leader in the development and manufacturing of advanced dental radiography products and 3-D diagnostic imaging technology. The agreement will expand Henry Schein’s diagnostic imaging technology offerings within the United States and Canada. Imaging Sciences reported sales of $25 million in 2005 in the United States and Canada.

Imaging Sciences’ products provide enhanced imaging speed and accuracy, enabling dentists to create more anatomically accurate treatment plans, leading to successful surgical procedures and an overall higher quality of patient care. The company’s flagship offering—the i-CAT Cone Beam 3-D Imaging System—offers advantages over traditional X-ray machines, including; in-office CT scanning; better case management; less radiation; and advanced diagnostic data. This data is transferred to a computer, typically within minutes, and displayed on a 3-D mapping tool that allows dentists and technicians to easily format and select images for immediate viewing and diagnosis.

"There is no question that 3-D digital imaging is a key element of the technology-driven dental office of the future," said Stanley M. Bergman, Chairman and Chief Executive Officer of Henry Schein. "Imaging Sciences International is helping to set the standard for leadership in this growing market, and we are proud to have been selected as their exclusive distributor throughout the United States and Canada."

"In two years our Imaging Sciences sales force has taken the i-CAT and 3-D imaging from the concept stage to a market leadership position in the dental industry," said Christopher Scharff, Vice President of Sales for Imaging Sciences International. "We are thrilled to be working with the Henry Schein organization and believe that they are the most qualified and experienced company to take our imaging system into mainstream distribution. We are committed to join forces with Henry Schein and share our knowledge of this technology as we achieve great success and bring 3-D imaging to dentists across the country."

"Henry Schein's impressive track record of success in reaching the dental community and communicating the practice benefits of technology-driven products make the company the ideal partner," said Edward Marandola, President and CEO of Imaging Sciences International. "We are confident that our 3-D imaging system can enhance dental practices by enabling practitioners to provide higher quality care with the most advanced in-office imaging capabilities. We are looking forward to this exclusive distribution agreement as a way to further build on our past success and take full advantage of future opportunities."
