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 May 29, 2008 and filed on June 2, 2008, the reporting person received a grant of 2,000 Restricted Stock Units ("RSUs") on May 29, 2008. On May 12, 2011, 50% of these RSUs vested, resulting in the issuance of 1,000 shares of Mattel common stock.
(2) The RSUs were granted on May 13, 2011, pursuant to the Mattel, Inc. 2010 Equity and Long-Term Compensation Plan. Each RSU represents a contingent right to receive one share of Common Stock (or, at the election of Mattel, Inc., a cash amount equal to the fair market value of such share on the settlement date). The RSUs are accompanied by dividend equivalent rights.
(3) The RSUs will vest in four equal installments, as follows: (i) 25% on August 13, 2011, (ii) 25% on November 13, 2011, (iii) 25% on February 13, 2012 and (iv) 25% on the earlier of May 13, 2012 or the day before the first annual meeting of Mattel's stockholders that occurs after the grant date. Vested RSUs generally will be settled on the third anniversary of the grant date. On the settlement date, for each vested RSU, the reporting person will receive one share of Common Stock (or, at the election of Mattel, Inc., a cash amount equal to the fair market value of one share of Common Stock on the settlement date).

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
