SUBSEQUENT EVENT

On January 31, 2012, we consummated the transactions contemplated by an Asset Purchase Agreement we executed with Ostial Solutions, LLC, a privately-held company based in Kalamazoo, Michigan ("Ostial Solutions"), and acquired substantially all of the assets of Ostial Solutions under terms which required $10.0 million of the purchase price to be paid at closing, $6.5 million of the purchase price to be paid within six months of closing and additional payments of up to $13.5 million based on our future product sales. The primary asset of Ostial Solutions is the patented Ostial Pro® Stent Positioning System, which facilitates precise stent implantation in coronary and renal aorto-ostial lesions, eliminating guesswork when deploying a stent at the "true" ostium of the vessel. The initial accounting for this acquisition has not yet been completed.
