Item 1.01. Entry into a Material Definitive Agreement.

On October 16, 2018, Oaktree Strategic Income II, Inc. (the “Company”) entered into a revolving credit agreement (the “Credit Agreement”) between the Company, as borrower, and City National Bank, as lender (“CNB”). The Credit Agreement provides for a senior secured revolving credit facility (the “Credit Facility”) of up to $100 million (the “Maximum Commitment”) in aggregate principal amount, subject to (i) the lesser of a percentage of unfunded commitments from certain classes of eligible investors in the Company and (ii) the Maximum Commitment. The maturity date of the Credit Facility is October 15, 2020. Borrowings under the Credit Facility bear interest at a rate equal to (a) the London Interbank Offered Rate (“LIBOR”) for the selected period plus 1.65% for LIBOR loans or (b) the prime rate of CNB minus 0.25% for prime rate loans. There is a non-usage fee of 25 basis points per year on the unused portion of the Credit Facility, payable quarterly.

The Credit Facility is secured by a first priority security interest, subject to customary exceptions, in (i) all capital commitments of investors in the Company, (ii) the Company’s right to make capital calls, receive payment of capital contributions from investors and enforce payment of capital commitments and capital contributions under the Company’s subscription agreements with investors and other operative documents and (iii) a cash collateral account into which the capital contributions from investors are made. The Company has made customary representations and warranties and is required to comply with various affirmative and negative covenants, reporting requirements and other customary requirements for similar credit facilities. The borrowings of the Company, including under the Credit Facility, are subject to the leverage restrictions contained in the Investment Company Act of 1940, as amended.

The description above is only a summary of the material provisions of the Credit Agreement and is qualified in its entirety by reference to the Credit Agreement, which is filed as Exhibit 10.1 to this current report on Form 8-K and incorporated by reference herein.
