This Amendment No. 1 constitutes an amendment only with respect to the Reporting Persons. Subsequent to the filing of the Schedule 13D, the Reporting Persons have elected to file future reports under Section 13 of the Exchange Act separately from Everest, and have determined that the Reporting Persons no longer beneficially own the Ordinary Shares held of record and beneficially by Everest. As of the date of this filing, Everest has reported, in a separate amendment to the Schedule 13D, that it beneficially owns an aggregate of 42,524,716 Ordinary Shares (the "Everest Shares"). The beneficial ownership information included in this Amendment No. 1 does not include the Everest Shares. The Reporting Persons explicitly disclaim beneficial ownership of the Everest Shares and the existence of a "group," within the meaning of Section 13(d)(5) and Rule 13d-5 of the Exchange Act, among the Reporting Persons and Everest. The reference to the Everest Shares herein, as well as the previous filing of Section 13 reports jointly by the Reporting Persons and Everest, shall not be deemed to be an admission that the Reporting Persons and Everest constitute, or have ever constituted, a group or that any Reporting Person beneficially owns, within the meaning of Section 13 of the Exchange Act, the Everest Shares. On a going forward basis, the Reporting Persons do not intend to amend this filing to reflect changes in Everest's beneficial ownership of Ordinary Shares and the Reporting Persons direct investors to the separate Section 13 reports filed by Everest for such information. Except as amended hereby, the Schedule 13D remains in full force and effect. All capitalized terms contained but not otherwise defined herein shall have the meanings ascribed to such terms in the Schedule 13D. Responses to each item of the Schedule 13D, as amended by this Amendment No. 1, are incorporated by reference into the responses to each other item, as applicable.
