Based on a preliminary count, 8,645,082 shares of Cardiac Pathways were tendered and accepted for payment at a price of $5.267 per share, resulting in Boston Scientific's ownership of approximately 95.48% of the outstanding common stock of Cardiac Pathways. All shares validly tendered and not withdrawn prior to the expiration of the offer have been accepted for payment according to the terms of the offer.
