Hologic and Siemens Announce Intent to Form Strategic Alliance
The Alliance to Focus on Second Generation Digital Mammography Systems
BEDFORD, Mass., and ERLANGEN, Germany

Hologic, Inc. (NASDAQ: HOLX) and Siemens AG (NYSE: SI), today announced that the two companies have executed a Letter-of-Intent to enter into a strategic alliance focused on the development of second-generation digital mammography systems. Through this alliance, these global medical technology leaders are planning to combine Hologic's proprietary amorphous selenium direct-to-digital mammography technology with Siemens' proprietary software for a dedicated physician's workstation. The parties intend to negotiate the details of this alliance over the next several months.

"We are delighted to have the opportunity to partner with Siemens, long recognized as an innovative leader in medical imaging and mammography technology," commented Hologic's President and CEO Jack Cumming. "Moreover, we believe Siemens' interest in Hologic's amorphous selenium direct digital detector is further validation of our significant technical achievements in the development of this technology."

Through the intended alliance, Siemens and Hologic are proposing to combine their proprietary mammography technologies and expertise to bring to market the first true, direct-to-digital mammography systems. Siemens and Hologic are also discussing joint efforts to migrate the current technology to the next generation of mammography systems, with the goal of providing clinicians with the capability of performing highly sophisticated, "breakthrough" imaging procedures of the breast.

In addition, Siemens and Hologic intend to partner on developing an image acquisition console that will offer customers a fully integrated approach to breast cancer detection. Proprietary Siemens software will be used to build a dedicated physician's workstation that will be designed to improve workflow and patient throughput, and also will be prepared to integrate future digital computer-aided detection (CAD) applications.

"Both Hologic and Siemens share a common mission for developing innovative and leading-edge technologies. Our ability to leverage our proprietary technologies and research and development resources should strengthen our product offerings and competitive positions in the emerging digital mammography market," said Cumming. "In understandable, grass-roots terms, it is the sincere hope of both companies, that through our collective efforts, we will soon offer enhanced visualization capabilities for clinicians, thereby assisting in the early detection of breast cancer. That's what this is all about, joining forces with Siemens in the fight against breast cancer."

"We believe this alliance will be very rewarding for both companies and for the advancement of mammography technology," agrees Holger Schmidt, president of Special Systems Division of Siemens Medical Solutions. "This partnership and the resulting products should offer our customers significant improvement in the quality of patient care, increased efficiency and long-term cost-savings. Our decision to combine both companies' vast resources and proprietary technologies should positively impact each of our digital mammography development programs."

At the Annual Meeting of the Radiological Society of North America (RSNA), Siemens and Hologic will mutually display the technologies that are the foundation of this partnership. Siemens, located in booth #6413, will be displaying Hologic's direct-to-digital mammography detector, which is based on the company's proprietary amorphous selenium technology. Hologic, located in booth #4329, will be utilizing Siemens' state-of-the-art software in its digital mammography workstation. RSNA 2001 is being held in Chicago, Illinois from November 25 - November 30, 2001.
