Kim family of which the reporting person is a general partner. The reporting person disclaims beneficial ownership of these securities, except to the extent of the reporting person's pecuniary interest therein, and this report shall not be deemed an admission that the reporting person is the beneficial owner of such securities, except to the extent of the reporting person's pecuniary interest therein, for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or for any other purpose.

(10)	(Continued From Footnote 9) Each of the aforementioned trusts to which the reporting person transferred shares of the Issuer's Common Stock or from which the reporting person received such shares is a grantor retained annuity trust of which the reporting person is the settlor, the sole current beneficiary and a co-trustee. Pursuant to the Form 5 instructions, in her capacity as a co-trustee of the trusts, the reporting person is being treated as having a pecuniary interest in all of the shares held by such trusts. Accordingly, transfers between the reporting person and such trusts result in mere changes from direct to indirect ownership or vice versa. Such transfers are therefore not reported on this Form 5. On December 31, 2020, such grantor retained annuity trusts held 4,622,043 shares of the Issuer's Common Stock.
