Explanation of Responses:

1. Received from Rice Acquisition Sponsor LLC ("Sponsor") pursuant to the pro rata distribution of all of the securities of the issuer held by Sponsor to its members.

2. Prior to the distribution by Sponsor referred to in footnote 1, the reporting person was a managing member of Sponsor, and as such, the reporting person may have been deemed to have beneficial ownership of the securities held of record by Sponsor and the reporting person's prior Form 4s included transactions and direct holdings of Sponsor.

3. The Derham Children's Trust of 2020 (the "Trust") is the record holder of the securities reported herein and the reporting person is the trustee of the Trust. By virtue of the relationship, the reporting person may be deemed to have or share beneficial ownership of the securities held of record by the Trust, but the reporting person disclaims any beneficial ownership of the reported securities other than to the extent of any pecuniary interest he may have therein, directly or indirectly.

4. The Class B Units of Opco are convertible into Class A Units of Opco on a one-for-one basis pursuant to the terms of the limited liability agreement of Opco. The Class A Units of Opco (together with the corresponding shares of the issuer's Class B common stock) are then exchangeable into shares of the issuer's Class A common stock or cash, at the issuer's election, on a one-for-one basis and have no expiration date.
