     ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.

     On June 1, 2004, Boston Scientific Corporation (the "Registrant") and
Advanced Bionics Corporation, a privately held company located in Valencia, CA,
announced the execution of a definitive merger agreement under which the
Registrant will acquire 100 percent of the fully diluted equity of Advanced
Bionics for an initial payment of approximately $740 million in cash, plus earn
out payments tied to future performance milestones. The acquisition will expand
the Registrant's technology portfolio into the rapidly growing implantable
microelectronic device market. Advanced Bionics has developed implantable
microelectronics for treating numerous neurological disorders. Its
neuromodulation technology includes a range of neurostimulators (or implantable
pulse generators), programmable drug pumps and cochlear implants.

     The acquisition has been structured to include a substantial earnout
mechanism. Performance milestones are primarily based on the achievement of net
sales, with certain milestone payments also tied to profitability. The
milestones are segmented by the four principal technology platforms (cochlear
implants, implantable pulse generators, drug pumps and bion microstimulators),
each with a 72-month earnout horizon.

     There are also bonus earnout payments available based on the attainment of
certain aggregate sales performance targets and a certain gross margin level.
The transaction is expected to close within days of the announcement. The
Registrant expects the acquisition to be modestly dilutive to earnings per share
(approximately $0.04 and $0.06 in 2004 and 2005, respectively).

     ITEM 9. REGULATION FD DISCLOSURE.

     On June 1, 2004, the Registrant issued a press release regarding the
execution of a Merger Agreement. A copy of this release is attached hereto as
