(1) The forfeiture reported in this form represents restricted stock units that were withheld by the Company solely for the purpose of satisfying tax obligations arising upon the automatic vesting of 53,125 restricted stock units.
(2) This includes 212,500 unvested restricted stock units.
(3) The Reporting Person received an aggregate of 85,000 restricted stock units, which, if eligible, shall vest in three (3) equal annual installments beginning on the third business day following the Company's public announcement of its earnings for the fiscal quarter ending June 30, 2010, and the second and third installments vesting on June 1, 2011 and June 1, 2012, provided the Reporting Person remains with the Company through each such vesting date. All or a portion of the restricted stock units may be eligible based upon the achievement of certain financial performance targets for the twelve-month period ending June 30, 2010. Restricted stock units that do not become eligible are forfeited. Each restricted stock unit represents a contingent right to receive one (1) share of the Issuer's Common Stock.
(4) This includes 297,500 unvested restricted stock units.
(5) One quarter (1/4th) of the shares subject to the option will vest on June 1, 2010, and one forty-eighth (1/48th) of the shares subject to the option will vest each month thereafter on the first day of each month, provided the Reporting Person remains with the Company through each such vesting date.
(6) $0.00 is used for technical reasons as there is no price for this derivative security until exercised.
