MARKET TRENDS & QUARTERLY HIGHLIGHTS Yield seeking investors continue to drive demand for private credit funds focused on the middle market The broadly syndicated leveraged finance markets largely recovered from the fourth quarter 2018 volatility providing for the opportunistic rotation out of discounted purchases into new originations and club deals However, the market volatility in the fourth quarter 2018 resulted in slower than normal deal activity during the first half of 2019 Given the heightened competition for quality deals across the middle market, we continue to find the relative value in larger club and syndicated deals more attractive as compared to lower middle market deals We also continue to focus on servicing our existing sponsor clients who are seeking add-on acquisition financings, recapitalizations and new business CURRENT MARKET TRENDS QUARTERLY HIGHLIGHTS New par additions during Q2 2019 totaled $24.6 million across 2 new portfolio companies at a weighted average yield at cost of 8.5% Repayments during Q2 2019 totaled $19.3 million in 1 portfolio company at a weighted average yield at cost of 7.5% Declared a Q3 2019 dividend of $0.23 per share payable on September 20, 2019 to shareholders of record as of September 6, 2019 The portfolio metrics were mostly unchanged from the prior quarter, with weighted average leverage at 3.9x and a weighted average risk grade at 2.3 as of June 30, 2019 Subsequent to quarter end, we made further progress on deploying our remaining capacity by closing $14.2 million of deals with $15.5 million of cash available through our SBIC subsidiary

EARNINGS HIGHLIGHTS FINANCIAL HIGHLIGHTS Earned net investment income of $0.22 per share for the second quarter, which was $0.02 per share higher than prior quarter due to: Higher net interest income resulting from a larger interest-bearing portfolio due to deployment of the additional capacity provided by our upsized CLO; partially offset by Slightly higher expenses driven by increased interest expense and incentive fees The change to our incentive fee structure effective as of January 1, 2019 has resulted in aggregate savings of $0.05 per share for the six months ended June 30, 2019 Net realized and unrealized losses on investments of $2.1 million, or $0.13 per share, for the three months ended June 30, 2019 were primarily driven by net negative market related adjustments across various syndicated investments QUARTERLY RESULTS OF OPERATIONS ($ in thousands, except per share data) Q2 2019   Q1 2019   Q4 2018   Q3 2018   Q2 2018 Total investment income $ 10,704   $ 10,229   $ 9,561   $ 9,312   $ 9,688 Total expenses 7,230   6,982   6,401   5,578   5,303 Net investment income 3,474   3,247   3,160   3,734   4,385 Net realized (loss)/gain on investments (2,365)   (7,133)   13   (27)   318 Net change in unrealized gain/(loss)on investments 284   6,296   (8,886)   (2,218)   (1,856) Loss on refinancing of debt - - (2,218) - - Net increase/(decrease) in net assets resulting from operations 1,393   2,410   (7,931)   1,489   2,847                   Net investment income per share 0.22   0.20   0.20   0.23   0.27 Net realized/unrealized losses from investments per share (0.13)   (0.05)   (0.56)   (0.14)   (0.09) Loss on refinancing of debt per share -   -   (0.14)   -   - Net earnings/(loss) per share 0.09   0.15   (0.50)   0.09   0.18 Dividends declared per common share 0.23   0.23   0.23   0.28   0.28 Net asset value per share 10.30   10.44   10.52   11.25   11.44
