Explanation of Responses:
( 1)  Each restricted stock unit represents a right to receive one share of HeartWare common stock.
( 2)  Pursuant to the Merger Agreement, each unvested restricted stock unit was automatically cancelled as of the Effective Time and converted into the right to receive an amount in cash equal to the product of (i) $58.00 multiplied by (ii) the number of shares of HeartWare common stock subject to such restricted stock unit as of immediately prior to the Effective Time (with any such restricted stock units that are subject to performance-based vesting being deemed earned assuming achievement of all performance milestones), less any required withholding of taxes.
( 3)  Pursuant to the Merger Agreement, each option that was outstanding and unexercised immediately prior to the Effective Time and for which the exercise price of such option was less than $58.00 per share, without regard to the extent vested or exercisable, was automatically canceled as of the Effective Time and converted into the right to receive a cash payment equal to the product of the excess of $58.00 over the exercise price of such option and the number of unexercised shares of HeartWare common stock subject to such option immediately prior to the Effective Time, less any required withholding of taxes. Each option for which, as of the Effective Time, the exercise price of such option was greater than $58.00 was automatically cancelled as of the Effective Time without any consideration being paid in respect thereof.
