| F6 | The terms of the Second Amended and Restated Agreement of Limited Partnership of Sitio Royalties Operating Partnership, LP ("Opco") provide that, subject to certain restrictions contained therein, each holder of the common units ("Opco Units") in Opco (other than Sitio Royalties Corp. (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. |
| F7 | (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.
