Explanation of Responses:

( 1 )Includes 6,838 restricted stock units ("RSUs") of the Issuer held by the Reporting Person immediately prior to the Effective Time (as defined below). ( 2 )Pursuant to the Agreement and Plan of Merger, dated October 16, 2022 (the "Merger Agreement"), by and among the Issuer, LFG Acquisition Holdings LLC ("Opco"), BP Products North America Inc. ("Parent"), Condor RTM Inc. ("Merger Sub") and Condor RTM LLC ("Opco Merger Sub"), Merger Sub merged with and into the Issuer, with the Issuer surviving as a wholly owned subsidiary of Parent (the "Issuer Merger"), and Opco Merger Sub merged with and into Opco, with Opco continuing as the surviving company and a wholly owned subsidiary of Parent (the "Opco Merger"). ( 3 )At the effective time of the Issuer Merger (the "Effective Time"), each share of the Issuer's Class A common stock, par value $0.0001 per share ("Class A Common Stock"), that was issued and outstanding as of immediately prior to the Effective Time (other than Owned Company Shares or Dissenting Company Shares, each as defined in the Merger Agreement) was automatically canceled, extinguished and converted into the right to receive $26.00 in cash, without interest (the "Per Share Price"). ( 4 )Pursuant to the Merger Agreement, each RSU reported hereby was, at the Effective Time, automatically canceled and converted into the right to receive an amount in cash (without interest and subject to applicable withholding taxes) equal to the product of (i) the total number of shares of Class A Common Stock subject to such RSU, as of immediately prior to the Effective Time, and (ii) the Per Share Price. ( 5 )Pursuant to the Merger Agreement, at the Effective Time, each share of the Issuer's Class B common stock, par value $0.0001 per share ("Class B Common Stock"), was automatically canceled and extinguished without any conversion thereof or consideration paid therefor. ( 6 )The Reporting Person is the sole managing member of Rice Investment Group UGP, LLC, which is the general partner of both (i) Shalennial GP I, L.P. (the general partner of Shalennial Fund I, L.P. ("Shalennial Fund")) and (ii) Rice Investment Group, L.P. (the management company for Shalennial Fund). As such, the Reporting Person may have been deemed to have had beneficial ownership of the securities held of record by Shalennial Fund. The Reporting Person disclaims any beneficial ownership of the reported securities other than to the extent of any pecuniary interest he may have had therein, directly or indirectly. ( 7 )Prior to the Effective Time, the Class A Units of Opco (each, an "Opco Unit") (together with the corresponding shares of Class B Common Stock) were exchangeable into shares of Class A Common Stock on a one-for-one basis and had no expiration date. At the effective time of the Opco Merger (the "Opco Merger Effective Time"), pursuant to the Merger Agreement, each Opco Unit held by a holder other than the Issuer or any of its subsidiaries issued and outstanding as of immediately prior to the Opco Merger Effective Time was automatically canceled, extinguished and converted into the right to receive cash in an amount equal to the Per Share Price.
