WHEREAS, the Company is a newly organized non-diversified, closed-end management investment company that has elected to be treated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (together with the rules promulgated thereunder, the “Investment Company Act”);

WHEREAS, the Adviser is registered as an investment adviser under the Investment Advisers Act of 1940, as amended (together with the rules promulgated thereunder, the “Advisers Act”);

WHEREAS, the Adviser renders advice and services to the Company pursuant to the terms and provisions of an Investment Advisory Agreement between the Company and the Adviser dated as of September 25, 2023 (the “Advisory Agreement”);

WHEREAS, the Company is responsible for, and has assumed the obligation for, payment of certain expenses pursuant to the Advisory Agreement that have not been assumed by the Adviser; and

WHEREAS, the Adviser desires to waive the Management Fee and the Incentive Fee (as those terms are defined in Section 3 of the Advisory Agreement) pursuant to the terms and the provisions of this Agreement, and the Company desires to allow the Adviser to implement such waivers.

NOW, THEREFORE, in consideration of the premises and the covenants hereinafter contained and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the Company and the Adviser hereby agree as follows:

Section 1. Fee Waiver on Management Fee. The Adviser hereby agrees to waive the Management Fee (as defined in Section 3 of the Advisory Agreement) in its entirety for the term of this Agreement.

Section 2. Fee Waiver on Incentive Fee. The Adviser hereby agrees to waive the Incentive Fee (as defined in Section 3 of the Advisory Agreement) in its entirety for the term of this Agreement.

Section 3. Term. This Agreement shall become effective on the date specified herein and continue for a one-year term, unless sooner terminated as provided in Section 4 of this Agreement.

Section 4. Termination. This Agreement may be terminated at any time, and without the payment of any penalty, by (i) the vote of the board of directors of the Company (the “Board
