(NASDAQ: HOLX), a leading provider of women's diagnostic imaging systems and state-of- the-art digital imaging systems, today announced that two executives of the company have established trading plans adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934 and the Company's insider trading policy.

Rule 10b5-1(c) allows officers and directors to adopt written plans to sell shares under pre-arranged terms when they do not have material nonpublic information. The rule allows officers and directors adopting such plans to sell shares over a specified amount of time, at specific prices in the future, even if subsequent material and non-public information becomes available to them. Using these plans, officers and directors can gradually diversify their investment portfolios, can spread stock trades out over an extended period of time to reduce any significant market impact and can avoid concerns about whether they had material nonpublic information when they sold their stock.
