As Jim Tobin and Lucia Quinn recently announced, Boston Scientific is launching the Stock Option Exchange Program for eligible employees effective today, Tuesday, May 22, 2007.

If you have eligible options, which are those with an exercise price of $25.00 or higher, and if you decide to participate in the Stock Option Exchange Program and exchange eligible stock option grants for a lesser number of DSUs, you must make your election before the offer expires at 11:59 p.m. Eastern Daylight Time on Monday, June 18, 2007. Throughout the program offer period, you will be able to edit your elections; however, all final elections must be submitted on or before the deadline.

You will be able to make your election to participate in the exchange program on the Stock Option Exchange Program Portal at https://www.corp-action.net/Bostonscientific/. For security purposes, a personal identification number (PIN) has been assigned to you.

Your PIN is: <PIN>

Please visit the Stock Option Exchange Program Portal and follow the instructions to access your personal information, including a summary of your stock option grants that are eligible for exchange, and submit your election by the deadline. If you decide not to participate in the exchange program, you don’t need to do anything.
