The option vests and becomes exercisable with regard to (a) 33% of the shares granted on the first anniversay of the date of grant, (b) an additional 33% of the shares granted on the second anniversary of the date of grant, and (c) the remaining 34% of the shares granted on the third anniversary of the date of grant.
(2)	The Restricted Stock Units ("RSUs" or the "Units") vest as to 50% of the Units granted on the second anniversary of the date of grant and as to the remaining 50% of the Units granted on the third anniversary of the date of grant. On each vesting date, for each Unit vesting on such date, the reporting person will receive one share of Mattel common stock (or, at the election of Mattel, a cash amount equal to the fair market value of one share of common stock on the date of vesting), subject to tax withholding.
(3)	The RSUs were granted pursuant to the 2010 Plan. Each Unit represents a contingent right to receive one share of Mattel common stock (or, at the election of Mattel, a cash amount equal to the fair market value of such share on the settlement date).
