6 Small - Cap Market Overview Unstructured and Inefficient Market ▪ Sourcing small - cap lending opportunities requires access to an extensive network of relationships in the small - business community (as opposed to the established investment banking sources for larger companies) Specialized Lending Requirements ▪ As a result of small - cap companies having limited resources to facilitate a financing process, there is an opportunity to create an informational advantage through a more rigorous due diligence and underwriting process Credit Supply / Demand Imbalance ▪ We believe commercial banks, investment banks, CLOs and hedge funds have reduced small - cap lending efforts to focus on larger, more liquid asset classes ▪ Demand for debt financing from small - cap companies remains strong as these companies continue to require credit to refinance existing debt, to support growth initiatives and to finance acquisitions

7 Self - Originated Small - Cap Broadly Syndicated and Secondary Market Value Add for Investors ▪ Proprietary deals with limited competition, generally resulting in above market risk - return dynamics ▪ Larger, more liquid investments; competition among a large number of participants often drives down yields Number of Lenders ▪ Sole lender in most transactions ▪ Large number of lenders in syndicated transactions; less influence over process Due Diligence ▪ Direct access to management allows for more thorough diligence process to create potential informational advantages ▪ Limited access to management and owners/ sponsors at underwriting stage Terms/ Credit Metrics ▪ Moderate leverage levels, favorable lender terms ▪ Market process and equity sponsor influence often lead to more borrower - friendly terms Financial Covenants ▪ Control over documentation, resulting in tight operational and financial covenants ▪ Documentation controlled by agent; competitive market dynamics can result in less stringent covenant packages Monitoring ▪ Lead monitoring process, able to take quick action if any issues arise ▪ Often limited to predetermined compliance package; access to company controlled by the agent Compelling Small - Cap Lending Opportunities ▪ With access to H.I.G. Capital’s sourcing network, the Company is able to capitalize on more attractive self - originated small - cap transactions Directly originated loans to small - cap companies typically generate more attractive risk - adjusted returns relative to larger, broadly syndicated credits

8 WhiteHorse Finance Portfolio Composition ▪ Self - originated, proprietary transactions sourced through H.I.G.’s deal flow network − “Off market” opportunities primarily to non - sponsored, small - cap companies − Compelling risk - adjusted returns resulting from limited competition Direct Originations ▪ Short - term investments may be traded into or out of the portfolio opportunistically, depending on market conditions and the level of capital deployment.
