A copy of this agreement is attached as an exhibit hereto and incorporated herein by reference. New OpCo LLC Agreement On December 23, 2025, the Issuer completed an internal reorganization (the "Reorganization"), pursuant to which, among other things, each outstanding limited liability company interest of Viper Energy Partners LLC, a Delaware limited liability company and Viper's operating subsidiary ("Old OpCo"), was converted into an equivalent limited liability company interest issued by a newly-formed subsidiary of Viper, VNOM Holding Company LLC ("New OpCo"). In connection with the Reorganization, VNOM Sub, Inc., a wholly owned subsidiary of the Issuer, in its capacity as the managing member of New OpCo, along with the Reporting Persons and affiliates Tumbleweed Royalty IV, LLC, NGU Management LLC and EnCap Energy Capital Fund X, L.P. adopted the Amended and Restated Limited Liability Company Agreement of New OpCo (the "New OpCo LLC Agreement"). The New OpCo LLC Agreement provides the members of New OpCo with substantially the same rights and obligations as such members previously held as members of Old OpCo pursuant to the Fourth Amended and Restated Limited Liability Company Agreement of Old OpCo. The New Opco LLC Agreement provides that members of New OpCo may require the Issuer to redeem (each, a "Redemption") all or a portion of the shares of Viper Class B common stock, par value $0.000001 per share ("Class B Common Stock") held by such member, together with an equal number of units representing limited liability company interests in New OpCo ("New OpCo Units") (one share of Class B Common Stock and one New OpCo Unit, together, a "Paired Unit", and a Paired Unit that has in fact been tendered for Redemption, a "Tendered Unit"), in exchange for a number of shares of Class A Common Stock, equal to the number of Tendered Units. The New OpCo LLC Agreement also provides that, in lieu of any Redemption, the Issuer will be entitled, subject to the redeeming member's acceptance in writing, to purchase some or all of the Tendered Units from such redeeming member for an amount of cash equal to the product of (x) (A) the number of Tendered Units, multiplied by (B) the average of the daily closing prices per share of Class A Common Stock for the 20 consecutive trading days immediately prior to the date of determination, multiplied by (y) the percentage of such Tendered Units being settled in cash, expressed as a percentage of the total number of Tendered Units rounded up to the nearest Tendered Unit (with the remainder of any Tendered Units not settled in cash to be redeemed for shares of Class A Common Stock). The above description of the New OpCo LLC Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of such agreement, which is filed as an exhibit hereto and incorporated herein by reference. Except as set forth herein, none of the Reporting Persons or Listed Persons has any contracts, arrangements, understandings or relationships (legal or otherwise) with any person with respect to any securities of the Issuer, including, but not limited to, any contracts, arrangements, understandings or relationships concerning the transfer or voting of such securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or losses, or the giving or withholding of proxies.
