(1) The amount reported includes an aggregate of 211 shares of common stock acquired under the Registrant's Employee Stock Purchase Plan since the Reporting Person last filed a Form 4 with the Securities and Exchange Commission.
(2) This stock option was canceled pursuant to the Agreement and Plan of Merger, dated as of April 29, 2012, by and among the Registrant, Hologic, Inc. ("Hologic"), and Gold Acquisition Corp. (the "Merger Agreement"), in exchange for a payment in cash, without interest and less the amount of any required tax withholding, equal to the product of: (i) the excess of $82.75 (the per share merger consideration pursuant to the Merger Agreement) over the exercise price of the stock option; and (ii) the number of shares of common stock of the Registrant underlying the stock option.
(3) 25% of the shares subject to the stock option vest on February 10, 2013, and the remaining shares vest in equal monthly installments over the following three years.
(4) Pursuant to the Merger Agreement, these options were assumed by Hologic and converted into options to acquire that number of shares of Hologic common stock which is equal to the number of shares of common stock of the Registrant subject to such options immediately prior to the merger multiplied by 4.51174963 with a per share exercise price equal to the quotient determined by dividing the per share exercise price of such options immediately prior to the merger by 4.51174963.
(5) The performance stock rights were canceled pursuant to the Merger Agreement and converted into the right to receive a payment in cash, without interest and less the amount of any required tax withholding, equal to the product of: (i) $82.75 (the per share merger consideration pursuant to the Merger Agreement); and (ii) 4,290 (which amount equals 150% of the target number of shares of common stock of the Registrant underlying the performance stock rights).
(6) The performance stock rights were canceled pursuant to the Merger Agreement and converted into the right to receive a payment in cash, without interest and less the amount of any required tax withholding, equal to the product of: (i) $82.75 (the per share merger consideration pursuant to the Merger Agreement); and (ii) 5,988 (which amount equals 150% of the target number of shares of common stock of the Registrant underlying the performance stock rights).
