THIS FOURTH SUPPLEMENTAL INDENTURE (this “Fourth Supplemental Indenture”), dated as of November 13, 2023, is between NEW MOUNTAIN FINANCE CORPORATION, a Delaware corporation (the “Company”), and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee (the “Trustee”). All capitalized terms used herein shall have the meaning set forth in the Base Indenture (as defined below).

RECITALS OF THE COMPANY

The Company and the Trustee executed and delivered an Indenture, dated as of August 20, 2018 (the “Base Indenture” and, as supplemented by this Fourth Supplemental Indenture, the “Indenture”), to provide, among other things, for the issuance, from time to time, of the Company’s unsecured debt securities, in an unlimited aggregate principal amount (the “Securities”), in one or more series to be established by the Company under, and authenticated and delivered as provided in, the Base Indenture.

The Company desires to issue and sell up to $115,000,000 in aggregate principal amount of the Company’s 8.250% Notes due 2028 (the “Notes”).

The Company previously entered into the First Supplemental Indenture, dated as of August 20, 2018 (the “First Supplemental Indenture”), the Second Supplemental Indenture, dated as of September 25, 2018 (the “Second Supplemental Indenture”), and the Third Supplemental Indenture, dated as of November 2, 2022 (the “Third Supplemental Indenture”), each of which supplemented the Base Indenture. Neither the First Supplemental Indenture, the Second Supplemental Indenture, nor the Third Supplemental Indenture is applicable to the Notes.

Sections 901(4) and 901(6) of the Base Indenture provide that without the consent of Holders of the Securities of any series issued under the Indenture, the Company, when authorized by or pursuant to a Board Resolution, and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental to the Base Indenture to (i) change or eliminate any of the provisions of the Indenture when there is no Security Outstanding of any series created prior to the execution of the supplemental indenture that is entitled to the benefit of such provision and (ii) establish the form or terms of Securities of any series as permitted by Section 201 and Section 301 of the Base Indenture.

The Company desires to establish the form and terms of the Notes and to modify, alter, supplement and change certain provisions of the Base Indenture for the benefit of the Holders of the Notes (except as may be provided in a future supplemental indenture to the Indenture (each, a “Future Supplemental Indenture”)).

The Company has duly authorized the execution and delivery of this Fourth Supplemental Indenture to provide for the issuance of the Notes and all acts and things necessary to make this Fourth Supplemental Indenture a valid, binding, and legal obligation of the Company and to constitute a valid agreement of the Company, in accordance with its terms, have been done and performed.
