"Clinical data presented at ACC for the TAXUS® paclitaxel-eluting coronary stent will report on outcomes in a variety of high-risk patient populations," said Paul LaViolette, Chief Operating Officer of Boston Scientific. "We expect results will show continued positive data for the TAXUS Stents in these complex patients and lesions."

  Schedule of Events (all times are Central Time)

  Saturday, March 29
  -- ARRIVE Diabetic Analysis.  D. Lynn Morris, M.D., will present one-year
     outcomes from a pooled analysis of the ARRIVE 1 & 2 Registries,
     including subset data for 4,772 patients, including 1,530 diabetics.
     The ARRIVE program is designed to collect and analyze "real-world"
     safety and clinical outcomes data for the TAXUS® Express2™
     paclitaxel-eluting stent system in the treatment of patients with
     coronary artery disease.  The diabetic sub-group analysis is designed
     to evaluate clinical restenosis in diabetic patients and non-diabetics
     treated with the TAXUS Express2 Stent.  The results will be presented
     at 8:00 a.m., during an e-poster session.  The Company plans to issue a
     press release at this time.

  -- ARRIVE High-Risk Patient Analysis.  John M. Lasala, M.D., will present
     two-year data from 7,307 high-risk patients in the ARRIVE program.  The
     study is designed to capture long-term safety and effectiveness data of
     the TAXUS Express2 Stent in more complex patients treated in routine
     practice.  The results will be presented at 1:54 p.m., during a
     moderated e-poster session.  The Company plans to issue a press release
     at this time.

  Monday, March 31
  -- PROMUS™ and TAXUS Stents.  Results from the Spirit II Clinical Trial
     will be presented by Patrick W. Serruys, M.D., PhD, at 8:00 a.m.,
     during a Late Breaking Trial session in Grand Ballroom S100.  Dr.
     Serruys will provide a two-year data analysis of 300 patients treated
     with the XIENCE™ V (PROMUS) Stent or the TAXUS Express Stent.
     SPIRIT II is a randomized, non-inferiority trial designed to obtain CE
     Mark approval for both the XIENCE V and PROMUS Stents.  The PROMUS
     Stent is a private-labeled XIENCE V Everolimus-Eluting Coronary Stent
     System manufactured by Abbott and distributed by Boston Scientific.
     The Company plans to issue a press release at this time.

     PROENCY European Registry
     In February, Boston Scientific announced the start of its PROENCY
     (PROMUS™, ENdeavor® and CYpher®) European registry, which is
     the first of its kind to observe different 'olimus'-eluting coronary
     stents.  The study will collect real-life clinical outcome data for
     Boston Scientific's PROMUS Everolimus-Eluting Stent and compare them
     with data from Johnson & Johnson's Cypher® Sirolimus-Eluting Stent
     and Medtronic's Endeavor® Zotarolimus-Eluting Stent in patients
     treated in routine clinical practice.  Clinical investigators are
     currently being recruited for the U.S. phase of PROENCY, which will
     begin upon U.S. launch of the PROMUS Stent expected later this year.

  -- Biventricular Pacing Percentage in Heart Failure Patients.  Bruce
     Koplan, M.D., will present a meta-analysis comparing bi-ventricular
     pacing percentages and its impact on the combined risk of death and
     heart failure hospitalization.  The results will be presented at 9:00
     a.m., during an oral abstract session in Room S403.

  Tuesday, April 1
  -- TAXUS Stent in Large Vessels.  David A. Cox, M.D., will present an
     analysis of data from the TAXUS IV & V randomized clinical trials
     comparing the outcomes of drug-eluting stents versus bare-metal stents
     in patients with large vessels.  The results will be presented at
     8:30 a.m., during an oral abstract session in Room S103d.

  -- TAXUS IV/V Diabetic data.  Gregg W. Stone, M.D., will present
     three-year results from a pooled analysis of the TAXUS IV & V clinical
     trials, including angiographic and IVUS outcomes at nine months and
     clinical outcomes at three years for 317 diabetic patients and 862
     non-diabetic patients.  The goal of the study is to determine if
     diabetes is a risk factor for restenosis and adverse clinical outcomes
     in patients treated with the TAXUS Stent.  The results will be
     presented at 9:31 a.m., during an oral abstract session in Room S103d.
     The Company plans to issue a press release at this time.

  -- TAXUS Stent TLR meta-analysis.  Stephen G. Ellis, M.D., will present a
     meta-analysis of long-term follow-up data from more than 1,300 patients
     in the TAXUS clinical trial program with up to five years of follow-up.
     The study is designed to determine predictors of target lesion
     revascularization (TLR) and long-term outcomes in drug-eluting stent
     patients who develop in-stent restenosis.  The results will be
     presented at 9:43 a.m., during an oral abstract session in Room S103d.
     The Company plans to issue a press release at this time.
