As previously communicated and described in the Option Exchange Program materials, the exchange offer is schedule to close tomorrow, May 29, 2009 at 11:59 p.m., Eastern Time. If you wish to participate in the Option Exchange Program and have not done so already, or you wish to make changes to your current election, you must log into the following website and follow the directions listed: https://iRobot.equitybenefits.com (the “offer website”). Detailed information regarding the Option Exchange Program, including Frequently Asked Questions, can be found by clicking the Election Info tab on the offer website. (For individuals entering the offer website for the first time, you must enter a user name (this is your name as displayed in your iRobot email address, excluding the @irobot.com extension) and a password (this is the last 4 digits of your social security number). You will be required to change your password as soon as you log on and before you can access secure data.)
