(Continued from Footnote 2) each share of Sitio Class A Common Stock was converted into the right to receive one share of New Sitio Class A Common Stock. Contemporaneously with the filing of this Form 4 to reflect the disposition of securities by the Reporting Person in connection with the consummation of the Sitio Merger, the Reporting Person is filing a Form 4 with respect to New Sitio to report the acquisition by such Reporting Person of an equal number of shares of securities in connection with the consummation of the Sitio Merger. This Form 4 only reports the disposition of securities of the Reporting Person pursuant to the Merger Agreement and does not reflect sales of securities by the Reporting Person.

Footnote F4

Pursuant to the Merger Agreement, effective as of the First Effective Time and in connection with the consummation of the Sitio Merger, each outstanding restricted stock unit (including deferred share units) subject solely to time-based vesting and denominated in Sitio Class A Common Stock (collectively, the "Old Sitio RSUs") was cancelled and converted into an equivalent restricted stock unit (collectively, the "New Sitio RSUs"), on the same terms and conditions (including as to vesting and forfeiture) as were applicable under the Old Sitio RSUs,

Footnote F5

(Continued from Footnote 4) each of which represents a contingent right to receive the number of shares of New Sitio Class A Common Stock equal to the number of shares of Sitio Class A Common Stock subject to such Old Sitio RSUs immediately prior to the First Effective Time. As used herein, the term "RSUs" refers to (i) Old Sitio RSUs prior to the First Effective Time and (ii) New Sitio RSUs following the First Effective Time, in each case, unless the context requires otherwise.

Footnote F6

Represents Old Sitio RSUs granted to the reporting person pursuant to the Sitio Royalties Corp. Long Term Incentive Plan (the "Old Sitio LTIP") in the form of deferred share units (the "Old Sitio DSUs"), which were cancelled and converted into New Sitio RSUs in the form of deferred share units in connection with the consummation of the Sitio Merger as described above. Each Old Sitio DSU represented a contingent right to receive one share of Class A Common Stock.

Following vesting, the shares of Sitio Class A Common Stock underlying the Old Sitio DSUs would have been delivered to the reporting person as soon as administratively practicable following the termination of the reporting person's service relationship with the issuer for any reason.
