This presentation contains, in addition to historical information, certain forward-looking statements that are based on our current assumptions, expectations and projections about future performance and events. In particular, statements regarding future economic performance, finances, and expectations and objectives of management constitute forward-looking statements.

Although the forward-looking statements contained in this presentation are based upon information available at the time the statements are made and reflect the best judgment of our senior management, forward-looking statements inherently involve known and unknown risks, uncertainties and other factors, which may cause the actual results, performance or achievements to differ materially from anticipated future results. Important factors that could cause actual results to differ materially from expected results, including, among other things, those described in our filings with the Securities and Exchange Commission (“SEC”), including our annual report on form 10-K for the year ended December 31, 2017, and any subsequent Quarterly Reports on Form 10-Q under the caption “Risk Factors.” Factors that could cause actual results to differ include, but are not limited to: the state of the U.S. economy generally or in specific geographic regions; the general political, economic, and competitive conditions in the markets in which we invest; defaults by borrowers in paying debt service on outstanding indebtedness and borrowers' abilities to manage and stabilize properties; our ability to obtain financing arrangements on terms favorable to us or at all; the level and volatility of prevailing interest rates and credit spreads; reductions in the yield on our investments and an increase in the cost of our financing; general volatility of the securities markets in which we participate; the return or impact of current or future investments; allocation of investment opportunities to us by our Manager; increased competition from entities investing in our target assets; effects of hedging instruments on our target investments; changes in governmental regulations, tax law and rates, and similar matters; our ability to maintain our qualification as a REIT for U.S. federal income tax purposes and our exclusion from registration under the Investment Company Act; availability of desirable investment opportunities; availability of qualified personnel and our relationship with our Manager; estimates relating to our ability to make distributions to our stockholders in the future; hurricanes, earthquakes, and other natural disasters, acts of war and/or terrorism and other events that may cause unanticipated and uninsured performance declines and/or losses to us or the owners and operators of the real estate securing our investments; deterioration in the performance of the properties securing our investments that may cause deterioration in the performance of our investments and, potentially, principal losses to us; and difficulty or delays in redeploying the proceeds from repayments of our existing investments. These forward-looking statements apply only as of the date of this press release. We are under no duty to update any of these forward-looking statements after the date of this presentation to conform these statements to actual results or revised expectations. You should, therefore, not rely on these forward-looking statements as predictions of future events. This presentation also contains estimates and other statistical data made by independent parties and by us relating to market size and growth and other data about our industry. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. In addition, projections, assumptions and estimates of our future performance and the future performance of the markets in which we operate are necessarily subject to a high degree of uncertainty and risk. 2 Safe Harbor Statement
