Footnote F1

For each Class A or Class B unit of Rice Acquisition Holdings 3 LLC ("Opco"), the Reporting Person owns a corresponding Class B ordinary share of the Issuer. In connection with the Issuer's initial business combination, or in certain circumstances described in the Second Amended and Restated Limited Liability Company Agreement of Opco at specified times thereafter, the Class B units of Opco will convert into Class A units of Opco on a one-for-one basis, subject to adjustment. The Class A units of Opco (together with the corresponding Class B ordinary shares of the Issuer) will be exchangeable into Class A ordinary shares of the Issuer after the time of the Issuer's initial business combination on a one-for-one basis and have no expiration date.

Footnote F2

Includes 1,500,000 Class A ordinary shares of the Issuer underlying the 1,500,000 Class B units of Opco that are subject to forfeiture if the underwriters of the Issuer's initial public offering of units do not exercise their over-allotment option in full.
