*	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 31, 2017 and filed on February 2, 2017, the Reporting Person received a grant of 95,383 Restricted Stock Units ("RSUs" or "Units") on January 31, 2017. The RSUs vest as to (a) 33% of the Units granted on the first anniversary of the date of grant, (b) an additional 33% of the Units granted on the second anniversary of the date of grant, and (c) the remaining 34% 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, 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 31, 2019, the second 33% of these RSUs vested, resulting in the issuance of 31,476 shares of Mattel, Inc. Common Stock.
(2)	Pursuant to the terms of the January 31, 2017 RSU grant, 10,903 shares of Mattel, Inc. Common Stock were automatically withheld at vesting to cover required tax withholding.
(3)	As of January 31, 2019, the Reporting Person had a balance of $29,436.07 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.
