AP Talos and Debtco are the record owners of an aggregate of 14,032,096 shares of the Issuer’s Common Stock, which represents approximately 17.2% of the Issuer’s outstanding Common Stock. Each of AP Talos and Debtco disclaims beneficial ownership of any shares of the Issuer’s common stock owned of record by the other, and each of Management VII, AIF VII, Apollo Management, Management GP, Commodities Management, Commodities Management GP, Management Holdings and Management Holdings GP disclaims beneficial ownership of any shares of the Issuer’s common stock owned of record by the AP Talos or Debtco, in each case except to the extent of any pecuniary interest therein, and this report shall not be deemed an admission that any such entity is the beneficial owner of or has any pecuniary interest in, such securities for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or for any other purpose.

(a) See also the information contained on the cover pages of this Amendment No. 3 on Schedule 13D which is incorporated herein by reference. The percentage of Common Stock reported as beneficially owned by each Reporting Person is based on 81,707,594 shares of Common Stock outstanding as of April 28, 2021, as reported by the Issuer on Form 10-Q for the period ended March 31, 2021 filed with the Securities and Exchange Commission on May 6, 2021.

(b) By virtue of the mutual agreement to vote their Common Stock in favor of each nominee nominated pursuant to the Stockholders’ Agreement, the Reporting Persons may be deemed to be members of a “group” with, and may be deemed to have or share indirect voting power over the 25,926,683 shares of Common Stock held of record by, entities affiliated with Riverstone (“the Riverstone Stockholders”). The Reporting Persons expressly disclaim any beneficial ownership of shares held of record by the Riverstone Stockholders and the number of shares reported in the cover pages as shared voting power does not include those shares of Common Stock.
