For Immediate Release - November 24, 2003

Clarian Health Partners, formed in 1997, is a consolidated health care organization comprised of the Methodist Hospital, Indiana University Hospital and Riley Hospital for Children. Clarian Health Partners hospitals are considered by many to be the premier health care facilities in Indiana and the Midwest because of their commitment to excellence in patient care, education and research.

"Entering into this agreement with Clarian is particularly exciting for us," said Jack W. Cumming, Hologic's Chairman and Chief Executive Officer. "As an organization, Clarian is clearly focused on providing the highest quality of care for their patients, using state-of-the-art healthcare solutions. Their clinical specialists are among the most dedicated and passionate professionals in the industry. We believe Clarian's choice of Hologic as their sole-source supplier is recognition of our commitment to providing unsurpassed image quality and performance in our breast imaging systems. We look forward to working closely with Clarian Health Partners to provide their patients the best possible technologies for the early detection of breast cancer."

Hologic's comprehensive line of mammography products includes the Lorad SeleniaT, the industry's only full field digital mammography system using direct capture technology and the M-IV and Affinity Series of screen-film mammography systems. Both product lines incorporate Hologic's proprietary HTC® (High Transmission Cellular) Grid, which provides higher contrast images by reducing radiation scatter in two directions, and the FAST (Fully Automatic Self-Adjusting Tilt) Compression Paddle, which assures more uniform compression, for improved imaging and enhanced patient comfort. Hologic also provides both upright and prone stereotactic breast biopsy systems.

"We are pleased to partner with Hologic," said Richard Helsper, Vice President of Operations for Clarian Health Partners. "Hologic is a market leader and recognized for their technological leadership and innovation in diagnostic imaging systems. With the addition of the latest and best in women's diagnostic imaging systems, Clarian will enhance its position as the premier provider of women's services in Indiana and allow us to continue meeting our goal of delivering patient care, second to none."
