USE OF PROCEEDS

We estimate the total net proceeds of the offering to be $                , based on the public offering price of $                 per note and after deduction of the underwriting discounts and commissions and estimated offering expenses payable by us. The Fund will invest the net proceeds of any offering in accordance with the Fund’s investment objective and policies, and may use a portion of such proceeds, depending on market conditions, for other general corporate purposes. The Investment Adviser anticipates that the investment of the proceeds will be made in accordance with the Fund’s investment objective and policies as appropriate investment opportunities are identified, which is expected to substantially be completed within three months; however, changes in market conditions could result in the Fund’s anticipated investment period extending to as long as six months. This could occur if market conditions are unstable to such an extent that the Investment Adviser believes market risk is greater than the benefit of making additional investments at that time. Pending such investment, the proceeds of the offering will be held in high quality short term debt securities and instruments.

The Fund may also use the net proceeds from the offering to call, redeem or repurchase shares of its Series A Preferred Shares or Series B Preferred Shares, as applicable. To the extent permitted by the 1940 Act and Delaware law, the Fund may at any time upon notice redeem the Series A Preferred in whole or in part at a price equal to the $50 liquidation preference per share plus accumulated but unpaid dividends through the date of redemption. The distribution rate on the Series A Preferred Shares is 3.8%. The Fund will redeem all or any part of the Series B Preferred Shares that holders have properly submitted for redemption and not withdrawn during the 30-day period prior to each of December 26, 2021 and December 26, 2023 at the liquidation preference, plus any accumulated and unpaid dividends. The Series B Preferred paid distributions quarterly at an annualized dividend rate of 7.00% of the $50 per share liquidation preference for the quarterly dividend periods ending on or prior to December 26, 2019 (Year 1). During the last dividend period of Year 1, the Board determined that the dividend rate for the next eight quarterly dividend periods (Year 2 and Year 3) will be 4.00%. During the last dividend period occurring in Year 3, the Board will determine and publicly announce at least 30 days prior to the end of such dividend period a fixed annual dividend rate that will apply for all remaining dividend periods. The reset dividend rate will be neither less than an annualized rate of 4.00% nor greater than an annualized rate of 7.00%. See “Description of the Securities—Preferred Shares” in the Prospectus for a definition of “Year 1,” “Year 2” and “Year 3.”

CAPITALIZATION

[To be provided.]

ASSET COVERAGE RATIO

As provided in the 1940 Act and subject to certain exceptions, the Fund may issue debt and/or preferred shares with the condition that immediately after issuance the value of its total assets, less certain ordinary course liabilities, exceed 300% of the amount of the debt outstanding and exceed 200% of the sum of the amount of debt and preferred shares outstanding. The Fund’s notes are expected to have an initial asset coverage on the date of issuance of approximately     %.

SPECIAL CHARACTERISTICS AND RISKS OF THE NOTES

Liquidity Risk. An investment in our notes is subject to special risks. Our notes are not likely to be listed on an exchange or automated quotation system. We cannot assure you that any market will exist for our notes or if a market does exist, whether it will provide holders with liquidity. Broker-dealers that maintain a secondary trading market for the notes are not required to maintain this market, and the Fund is not required to redeem notes if an attempted secondary market sale fails because of a lack of buyers. To the extent that our notes trade, they may trade at a price either higher or lower than their principal amount depending on interest rates, the rating (if any) on such notes and other factors.

Reinvestment Risk. The Fund may at any time redeem notes to the extent necessary to meet regulatory asset coverage requirements. For example, if the value of the Fund’s investment portfolio declines, thereby reducing the asset coverage for the notes, the Fund may be obligated under the terms of the notes to redeem the notes. Investors may not be able to reinvest the proceeds of any redemption in an investment providing the same or a better rate than that of the notes.

Distribution Risk. The Fund may not meet the asset coverage requirements or earn sufficient income from its investments to make interest payments on the notes.

Redemption Risk. Although unlikely, precipitous declines in the value of the Fund’s assets could result in the Fund having insufficient assets to redeem all of the notes for the full redemption price.

TAXATION

UNDERWRITING

LEGAL MATTERS

Certain legal matters will be passed on by Skadden, Arps, Slate, Meagher & Flom LLP, Boston, Massachusetts, counsel to the Fund in connection with the offering of the notes.
