*	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 January 29, 2015 and filed on February 2, 2015, the Reporting Person received a grant of 27,881 Restricted Stock Units ("RSUs" or "Units") on January 29, 2015. The RSUs vest as to 33% of the Units on the first anniversary of the date of grant, 33% of the Units on the second anniversary of the date of grant and as to the remaining 34% of the Units on the third anniversary of the date of grant. On the vesting date, for each Unit vesting, the Reporting Person will receive one share of Mattel, Inc. 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 date of vesting), subject to tax withholding. On January 29, 2018, the final 34% of these RSUs vested, resulting in the issuance of 9,481 shares of Mattel, Inc. Common Stock.
(2)	Pursuant to the terms of the January 29, 2015 RSU grant, 3,279 shares of Mattel, Inc. Common Stock were automatically withheld at vesting to cover required tax withholding.
(3)	As of January 29, 2018, the Reporting Person had a balance of $24,765.73 in the Mattel Stock Fund of Mattel, Inc.'s 401(k) plan, the Personal Investment Plan ("PIP"). The number of shares has been calculated by the plan administrator for the PIP.
