(the "Issuer")) generally has the right to cause Opco to redeem all or a portion of its Opco Units (the "Redemption Right") in exchange for shares of Class A Common Stock of the Issuer on a one-for-one basis or, at Opco's election, an equivalent amount of cash.

7. (Continued from Footnote 6) The Issuer may, at its option, effect a direct purchase of such Opco Units for shares of Class A Common Stock of the Issuer in lieu of such a redemption by Opco. Upon the future redemption or sale of Opco Units pursuant to the Redemption Right, a corresponding number of shares of Class C Common Stock and Opco Units will be cancelled. The Opco Units and the right to exercise the Redemption Right have no expiration date.

8. On August 19, 2025, pursuant to the Agreement and Plan of Merger, dated as of June 2, 2025 (the "merger agreement"), each share of Class C Common Stock of the Issuer issued and outstanding was automatically cancelled and ceased to exist and the Opco Units converted into the right to receive (i) 0.4855 units representing limited liability company interests in Viper Energy Partners LLC and (ii) 0.4855 shares of Class B common stock of Viper Energy, Inc.

To the extent that a restricted stock award is forfeited, the shares of Class C Common Stock and Opco Units subject to such forfeited award will be returned to the Issuer.

10. (Continued from Footnote 9) In connection with the foregoing, the Issuer and the DPM Members entered into that certain Assignment and Allocation Agreement, dated as of June 7, 2022 (the "Allocation Agreement"), pursuant to which the Issuer agreed that it would re-issue to the DPM Members, on a one-for-one basis, shares of Class C Common Stock and Opco Units to the extent Restricted Shares are forfeited by the original holders thereof, with RRR Aggregator entitled to receive its pro rata portion of any such shares re-issued. The Reporting Persons are no longer entitled to receive such securities as all of the Stock Awards vested in connection with the closing of the transactions contemplated by the merger agreement.
