Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) As reported on a Form 4 dated August 1, 2009 and filed on August 3, 2009, the reporting person received a grant of 15,169 Restricted Stock Units ("RSUs" or "Units") on July 31, 2009. The RSUs vest as to 50% of the Units on the second anniversary of the date of grant and as to the remaining 50% of the Units 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. On July 31, 2012, the final 50% of these RSUs vested, resulting in the issuance of 7,585 shares of Mattel common stock.
(2) Pursuant to the terms of the July 31, 2009 RSU grant, 3,277 shares of Mattel common stock were automatically withheld at vesting to cover required tax withholding.
(3) As of July 31, 2012, the reporting person had a balance of $335,619.67 in the Mattel Stock Fund of Mattel's 401(k) Personal Investment Plan ("PIP"). The number of shares has been calculated by the plan administrator for the PIP.
