Voting and Support Agreement

On September 6, 2022, the Issuer, Sitio Royalties Operating Partnership, LP, a Delaware limited partnership (Sitio Opco), Snapper Merger Sub I, Inc., a Delaware corporation and wholly owned subsidiary of the Issuer (New Parent), Snapper Merger Sub II, LLC, a Delaware limited liability company and wholly owned subsidiary of Sitio Opco (Merger Sub), Brigham Minerals Inc., a Delaware corporation (Brigham), and Brigham Minerals Holdings, LLC, a Delaware limited liability company (Brigham Opco), entered into an agreement and plan of merger (the Merger Agreement), pursuant to which, subject to the satisfaction or waiver of the conditions set forth therein, at the applicable effective time (i) a newly formed Delaware corporation wholly owned by New Parent will merge with and into Brigham, with Brigham continuing as the surviving corporation and as a wholly owned subsidiary of New Parent, (ii) a newly formed Delaware corporation wholly owned by New Parent will merge with and into the Issuer, with the Issuer continuing as the surviving corporation and as a wholly owned subsidiary of New Parent, and (iii) Merger Sub will merge with and into Brigham Opco, with Brigham Opco continuing as the surviving entity and as a wholly owned subsidiary of Sitio Opco (the Merger).

Pursuant to the terms of the Merger Agreement and subject to the conditions therein, at the effective time of the Merger, Brigham shareholders will receive a fixed exchange ratio of 1.133 shares of common stock in the combined company for each share of Brigham common stock owned on the closing date, and the Issuers shareholders will receive one share of common stock in the combined company for each share of the Issuers common stock owned on the closing date. Brighams and the Issuers Class A shareholders will receive shares of Class A common stock in the combined company, and Brighams Class B and the Issuers Class C shareholders will receive shares of Class C common stock in the combined company as merger consideration. Completion of the Merger is subject to customary closing conditions, including regulatory clearance and approvals by the shareholders of the Issuer and Brigham.

In connection with the execution of the Merger Agreement, on September 6, 2022, Royal Aggregator and Rock Ridge (the Supporting Holders) entered into a voting and support agreement (the Voting and Support Agreement) with the Issuer and Brigham.

Pursuant to the Voting and Support Agreement, each of the Supporting Holders agreed, from and after the date of the Voting and Support Agreement until the Termination Date (as defined in the Voting and Support Agreement), to vote its shares of the Issuer owned as of the record date for such meeting (1) in favor of proposals relating to the transactions contemplated by the Merger Agreement and any other proposals necessary and appropriate in connection with the Transactions (as defined in the Merger Agreement) and (2) against any agreement, transaction or proposal relating to a Parent Competing Proposal (as defined in the Merger Agreement). Each Supporting Holder granted the Issuer an irrevocable proxy to vote its shares of the Issuer owned as of the record date for such meeting in accordance with the Voting and Support Agreement, effective immediately prior to the Issuer voting such shares.

The Voting and Support Agreement will terminate upon the earliest to occur of the following: (a) the date the Merger Agreement is validly terminated in accordance with its terms, (b) the Effective Time (as defined in the Merger Agreement), (c) an amendment to the Merger Agreement without the prior written consent of each Supporting Holder that (1) reduces the consideration payable in the Parent Merger (as defined in the Merger Agreement), (2) changes the form of consideration payable in the Parent Merger, or (3) extends the outside date under the Merger Agreement, subject to certain exceptions, and (d) mutual consent of the parties to the Voting and Support Agreement.

The foregoing description of the Voting and Support Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of such agreement filed as an exhibit to this Schedule 13D and is incorporated herein by reference.

Items 5.

Interest in Securities of the Issuer.

Items 5(a)-(c) of the Schedule 13D are hereby amended and restated as follows:
