(1) Amount of securities includes 682,500 Restricted Stock Units held by Reporting Person. Absent a change of control, shares of common stock will be distributed in exchange for Restricted Stock Units (after payment of $.01 par value per share) in three equal installments on January 1st of each of 2012, 2013 and 2014.
(2) Shares withheld by the Issuer for payment by the Reporting Person to the Issuer of his option exercise price.
(3) Shares withheld by the Issuer for payment by the Reporting Person of his tax withholdings.
(4) Option exercised is derived from an option to purchase 875,000 shares granted 8/12/2004 (the "Original Option"), which vested as follows: (i) as to 300,000 underlying shares on the date of grant; and (ii) and with respect to the remainder, 25,000 underlying shares vested monthly thereafter commencing on August 31, 2004 until fully vested. On 2/8/2006 the Original Option was bifurcated into two options to comply with Section 409A of the Internal Revenue Code; one with respect to 425,000 shares that had vested on or prior to 12/31/2004 (the "Pre-409A Option") and one with respect to 450,000 shares (the "Post-409A Option"), which vested and was exercisable on the same schedule as in the Original Option. The Pre-409A Option was previously exercised. The Post-409A Option, as amended on 2/8/2006 and 12/2007, is exercisable (absent a change of control) in four equal installments commencing on January 1 of each of 2011, 2012, 2013 and 2014.
