Capitalized terms used herein without definition shall have the meanings given to such terms in the Schedule 13D.

Subparagraphs a, b and c of Item 5 in the Schedule 13D are amended and restated in their entirety by the following:

(a) As of November 5, 2021, each of the Reporting Persons beneficially owns 8,971,525 shares of Common Stock of the Issuer, representing 20.3% of the issued and outstanding shares of Common Stock of the Issuer (based on 44,109,366 shares of Common Stock of the Company issued and outstanding as of November 1, 2021, as set forth in the Issuer’s quarterly report on Form 10-Q for the quarter ended September 30, 2021, filed with the SEC on November 2, 2021). Each Reporting Person disclaims beneficial ownership of the reported Common Stock except to the extent of such Reporting Person’s pecuniary interest therein, and this statement shall not be deemed an admission that such Reporting Person is the beneficial owner of the reported Common Stock for the purposes of Section 13(d) of the Exchange Act or any other purpose.

(b) As of November 5, 2021, Yorktown IX directly owns 8,971,525 shares of Common Stock of the Issuer. Yorktown IX Co is the sole general partner of Yorktown IX. Yorktown IX Associates is the sole general partner of Yorktown IX Co. Yorktown IX Associates has the sole power to cause Yorktown IX Co to cause Yorktown IX to vote or direct the vote or to dispose or direct the disposition of the shares owned by Yorktown IX.

(c) On November 5, 2021, Yorktown IX distributed in-kind, on a pro rata basis and for no additional consideration, in accordance with its limited partnership agreement, an aggregate of 2,500,000 shares of Common Stock of the Issuer, to its limited and general partners (the “First Distribution”). Upon the consummation of the First Distribution by Yorktown IX, Yorktown IX Co distributed in-kind, on a pro rata basis and for no additional consideration, in accordance with its limited partnership agreement, all 37,500 shares of Common Stock of the Issuer received in the First Distribution to its limited and general partners (the “Subsequent Distribution”).
