RECITALS

A. The San Juan Basin Royalty Trust (the “Trust”) is held under the San Juan Basin Amended and Restated Royalty Trust Indenture made effective as of December 12, 2007 (the “Indenture”). Any capitalized term used in this Agreement that is not otherwise defined in this Agreement shall have the meaning set forth in the Indenture.

B. Section 6.03 of the Indenture provides that “[t]he Trustee may resign, with or without cause, at any time by written notice to each of the then Unit Holders, given by first-class United States mail . . .” Section 6.05 of the Indenture provides that “if a Trustee has given notice of its intention to resign, the Unit Holders present or represented at a meeting held in accordance with the requirements of Article VIII may appoint a successor trustee.”

C. The Trustee previously provided to each of the Unit Holders, by first-class United States mail, the Conditional Notice of Intent to Resign by the Trustee of the San Juan Basin Royalty Trust attached to this Agreement as Exhibit A (the “Resignation Notice”). The Resignation Notice provided that the Trustee’s resignation would be effective on February 15^th, 2024 (the “Effective Date”) and contingent upon (i) the Unit Holders’ appointment of ARGENT as successor trustee of the Trust and approval of any amendments to the Indenture necessary to permit ARGENT to serve as successor trustee at a meeting of the Unit Holders, subject to the terms of this Agreement and that certain Agreement of Conditional Resignation, dated September 6, 2023 (the “Prior Agreement”), (ii) satisfaction of the covenants and conditions set forth in the Prior Agreement, and (iii) the execution of this Agreement.

D. Trustee and ARGENT previously entered into the Prior Agreement. The Prior Agreement contemplated that the Unit Holders would be asked to vote (i) to appoint ARGENT as successor trustee of the Trust; (ii) to amend Section 6.02 of the Indenture to clarify that the indemnification provisions of the Indenture apply to a former trustee; and (iii) to amend Section 6.05 of the Indenture to permit a successor trustee to be a bank or trust company having a capital, surplus and undivided profits (as of the end of its last fiscal year prior to its appointment) of at least $15,000,000 (the “Unit Holder Approval”), at a special meeting (the “Original Special Meeting”) of the Unit Holders; the Original Special Meeting was adjourned to January 16, 2024 at 10:00 AM CST and was held at 2200 Post Oak Blvd., Houston, Texas 77056 and virtually via webcast (the “Special Meeting”), subject to the terms of the Prior Agreement and this Agreement. At the Special Meeting, the Unit Holder Approval was received.

E. Trustee has expressed a desire for a judicial settlement of its accounts as trustee of the Trust to completely resolve all matters and potential controversies regarding Trustee’s administration of the Trust prior to its resignation, but is willing to forgo its right to seek a judicial review and discharge in exchange for the indemnity provided for in Section 6.02 of the Indenture (the entirety of Section 6.02 of the Indenture is referred to below as the “Existing Indemnity”).

6. Pursuant to the Resignation Notice, the Prior Agreement, and the Unit Holder Approval at the Special Meeting, the Parties have agreed to enter into this Agreement.
