( 1)  In connection with the merger of a subsidiary of Medtronic, Inc. into Issuer on August 12, 2010 (the "Merger") pursuant to an agreement and plan of merger dated April 28, 2010, all shares of Issuer common stock were converted into the right to receive $4 per share in cash.
( 2)  This option was cancelled in the merger in exchange for the right to receive a cash payment equal to the product of (i) the total number of shares subject to the options, multiplied by (ii) the excess, if any, of $4 over the exercise price per share of the shares subject to the option, less any applicable withholding taxes.
( 3)  1 unit for 1 share of Common Stock.
( 4)  This restricted stock unit, the vesting of which was accelerated in connection with the Merger, was cancelled in the merger in exchange for the right to receive a cash payment equal to the product of (i) the total number of shares of stock represented by the restricted stock unit, multiplied by (ii) $4 per share, less applicable withholding taxes.
( 5)  Vests as to 100% the earlier of this date, or the date of the second annual meeting following the date of grant.
