On November 5, 2018, Oaktree Strategic Income II, Inc. (the “Company”) delivered a capital drawdown notice to its investors relating to the sale of approximately 789,198 shares of its common stock, par value $0.001 per share (the “Common Stock”), for an aggregate offering price of approximately $15.6 million. This follows prior capital drawdown notices delivered by the Company on the dates and for the amounts indicated: each of July 27, 2018 and September 4, 2018, for approximately 770,869 shares of Common Stock each, with an aggregate offering price for each of approximately $15.4 million, and October 18, 2018 for approximately 1,060,964 shares of Common Stock for an aggregate offering price of approximately $21.1 million.

The sale of Common Stock is being made pursuant to subscription agreements entered into by the Company and its investors. Under the terms of the subscription agreements, investors are required to fund drawdowns to purchase Common Stock up to the amount of their respective capital commitments on an as-needed basis with a minimum of ten days’ prior notice to investors.

The issuance of the Common Stock is exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), pursuant to Section 4(a)(2) thereof and Regulation D and Regulation S thereunder. Each purchaser of Common Stock was required to represent that it is (i) either an “accredited investor” as defined in Rule 501 of Regulation D under the Securities Act or, in the case of the Common Stock sold outside the United States, not a “U.S. person” in accordance with Regulation S under the Securities Act and (ii) was acquiring the Common Stock for investment and not with a view to resell or distribute. The Company did not engage in general solicitation or advertising and did not offer securities to the public in connection with such issuances.
