ABIOMED, INC. TABLE OF CONTENTS ITEM PAGE ---- ---- Item 5 Other Events 1 Item 7 Financial Statements, Pro forma Financial Information and Exhibits 2 Signature 3 Exhibit E-1 ITEM 5. OTHER EVENTS. As previously described, ABIOMED is a defendant in an action filed on January 20, 1998 by World Heart Corporation and the Ottawa Heart Institute Research Corporation in the United States District Court for the District of Delaware. The complaint seeks damages and injunctive relief for alleged breaches of contract, misappropriation of trade secrets, conversion of trade secrets and patent infringement by ABIOMED. The plaintiffs' claims and allegations relate to a transcutaneous energy transmission device that was being developed by the Ottawa Heart Institute Research Corporation in connection with their left ventricular assist device under development. Between 1992 and 1995, we evaluated prototypes of the Ottawa Institute Research Corporation's transcutaneous energy transmission device for possible use in connection with the AbioCor(TM) implantable replacement heart and determined that it did not meet our needs. The plaintiffs allege that we subsequently utilized aspects of their proprietary technology in developing our own transcutaneous energy transmission device. We do not believe that we are infringing any intellectual proprietary rights of the plaintiffs, and have so stated in our answer to the complaint. We are vigorously defending the case. On October 20, 1999, World Heart Corporation informed us that they have determined that our transcutaneous energy transmission device does not infringe the asserted patent. ON NOVEMBER 22, 1999, THE PLAINTIFFS' FOURTH CAUSE OF ACTION, THE PATENT INFRINGEMENT CLAIM, WAS DISMISSED WITH PREJUDICE BY STIPULATION OF THE PARTIES. The plaintiffs continue to press the remaining claims. ABIOMED continues to seek the identification from the plaintiffs of any specific trade secrets that we have allegedly misappropriated. Unless action is taken by the plaintiffs or by the court to dismiss the remaining claims prior to trial, we intend to defend ourselves in court. Trial is scheduled to commence in early 2000. Although we believe the plaintiffs' claims and allegations to be without merit, it is possible that our defense may not prevail. If we do not prevail, we might be required to use or develop alternative transcutaneous or non-transcutaneous technology, to seek a license to use certain technology, or to modify the design of our transcutaneous energy transmission device. Although alternative technologies may be used to provide energy to the AbioCor system, such alternatives, though functional, may lack features of our current design. As a result, if we do not prevail, our AbioCor development project may be adversely affected and our business may be harmed. On May 7, 1999, we filed a motion requesting leave of court to assert a counterclaim alleging that World Heart Corporation and Ottawa Heart Institute Research Corporation misappropriated our trade secrets. The court has not yet acted on that motion. AbioCor is a trademark of ABIOMED, Inc. 1 ITEM 7.
