F1: Due to a rounding error, discovered on March 15, 2022, the original Form 4 filed on behalf of the Reporting Person on February 18, 2022 (the 'Original Form 4') reported the vesting of 24,462 shares of common stock. This Form 4/A amends that filing to reflect a vesting of 24,461 shares of common stock. As previously reported, these shares of common stock vested upon the determination by the Compensation Committee of the Issuer's Board of Directors of the satisfaction of performance criteria underlying an award of performance stock units granted to the Reporting Person on February 15, 2019 under the terms of the Issuer's 2013 Omnibus Incentive Plan.

F2: The Original Form 4 is further amended to disclose that 9,710 shares of common stock were sold to cover tax withholding obligations arising from the award. The Original Form 4 did not report the sale to cover tax withholding obligations because the number of shares to be sold was not known at the time of filing.

F3: 93,405,554 shares of Issuer are held through TTWF LP, a Delaware limited partnership, and TTWF GP LLC, a Delaware limited liability company and the general partner of TTWF LP. Two trusts for the benefit of members of the Chao family, including the reporting person, are the managers of TTWFGP LLC. The limited partners of TTWF LP are five trusts, principally for the benefit of members of the Chao family, including the reporting person, and two corporations owned, indirectly or directly, by certain of these trusts and by other entities owned by members of the Chao family, including the reporting person. The reporting person shares investment and voting power with respect to the shares beneficially owned by TTWF LP and TTWFGP LLC. The reporting person disclaims beneficial ownership of the shares except to the extent of his pecuniary interest therein.
