(NASDAQ: HOLX), a diversified medical technologies company specializing in diagnostic, imaging products and interventional devices dedicated to serving the healthcare needs of women, announced today the pricing of $1.5 billion aggregate principal
amount of convertible senior notes due 2037. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">The convertible senior notes mature in 2037 and will pay cash interest semiannually at a rate of 2.00% per
annum until December 15, 2013, after which their principal will accrete at a rate of 2.00% per annum. Commencing with the interest period beginning December 15, 2013, the notes will also pay contingent interest under certain circumstances based on
the trading price of the notes. The notes will be convertible at an initial conversion rate of 12.9555 shares of common stock per $1,000 original principal amount of notes (equivalent to a conversion price of approximately $77.1875 per share),
subject to adjustment. The initial conversion price represents a 25% premium over the closing sale price of Hologic&#146;s common stock on December 4, 2007. The sale of the convertible senior notes is expected to close on December&nbsp;10, 2007.
Hologic granted the underwriters an option to purchase up to an additional $225 million aggregate principal amount of the convertible notes to cover overallotments. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT
