("New Sitio"), Snapper Merger Sub IV, Inc. ("Brigham Merger Sub"), Snapper Merger Sub V, Inc. ("Sitio Merger Sub"), Snapper Merger Sub II, LLC ("Opco Merger Sub"), Brigham Minerals, Inc.

Footnote F2

(Continued from Footnote 1) (ii) the merger of Sitio Merger Sub with and into Sitio (the "Sitio Merger"), with Sitio surviving the Sitio Merger as a wholly owned subsidiary of New Sitio, and (iii) the merger of Opco Merger Sub LLC with and into Opco LLC (the "Opco Merger," and, together with the Brigham Merger and the Sitio Merger, the "Mergers"), with Opco LLC surviving the Opco Merger as a wholly owned subsidiary of Opco LP, in each case on the terms set forth in the Merger Agreement. As a result of the Mergers, Sitio and Brigham became direct wholly owned subsidiaries of New Sitio. Effective as of the effective time of the Sitio Merger (the "First Effective Time"),

Footnote F3

(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

Effective as of immediately prior to the First Effective Time, these deferred share units (the "Old Sitio DSUs") that were granted to the reporting person under the Sitio Royalties Corp. Long Term Incentive Plan were accelerated in full. In connection with the consummation of the Sitio Merger, the reporting person's service relationship with the issuer terminated and the reporting person ultimately received settlement of the Old Sitio DSUs in the form of a 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 DSUs.
