General Notices § This presentation is for general information purposes only and does not constitute legal, tax, investment or other professional advice on any subject matter. Information provided is not all-inclusive and should not be relied upon as being all-inclusive. § Certain statements in this presentation may constitute "forward-looking statements" within the meaning of the Federal Private Securities Litigation Reform Act of 1995 that are subject to risks and uncertainties that could cause results to be materially different than expectations. Forward-looking statements are statements that do not relate strictly to historical or current facts but reflect management's current understandings, intentions, beliefs, plans, expectations, assumptions and/or predictions regarding the future of the company's business and performance, the economy, and other future conditions and forecasts of future events and circumstances. Forward-looking statements are typically identified by words such as "continues," "could," "estimates," "expects," "maintains," "may," "should," "pursues," "will," the negative of such terms and words and terms of similar substance in connection with discussions of future operating or financial performance, business strategy and portfolios, projected growth prospects, cash flows, costs and financing needs, amount and timing of anticipated future distributions, estimates of per share NAV of the company's common stock, and/or other matters. § The company's forward-looking statements are not guarantees of future performance. While the company's management believes its forward-looking statements are reasonable, such statements are inherently susceptible to uncertainty and changes in circumstances. As with any projection or forecast, forward-looking statements are necessarily dependent on assumptions, data and/or methods that may be incorrect or imprecise and may not be realized. The company's forward-looking statements are based on management's current expectations and a variety of risks, uncertainties and other factors, many of which are beyond the company's ability to control or accurately predict. Important factors that could cause the company's actual results to vary materially from those expressed or implied in its forward-looking statements are set forth in the company's public filings. 3

General Notices § Although the company believes that the expectations reflected in such forward-looking statements are based upon reasonable assumptions, the company's actual results could differ materially from those set forth in the forward- looking statements due to a variety of risks, uncertainties and other factors. Given these uncertainties, the company cautions you not to place undue reliance on such statements. Forward-looking statements speak only as of the date on which they are made, and the company undertakes no obligation to, and expressly disclaims any obligation to, publicly release the results of any revisions to its forward-looking statements to reflect new information, changed assumptions, the occurrence of unanticipated subsequent events or circumstances, or changes to future operating results over time, except as otherwise required by law. § An investment in the company is subject to significant risks, some of which are summarized below in the "Risk Factors" section of this presentation. See also, "Risk Factors" in the company's public filings for a more detailed description of the risks associated with an investment in the company, copies of which may be obtained from the company's website. 4

Risk Factors § Investing in a non-traded real estate investment trust (REIT) is a higher-risk, longer term investment and is not suitable for all investors. Due to the risks involved in the ownership of real estate, there is no guarantee of any return on investment. The shares may lose value or investors could lose their entire investment. The shares are not FDIC-insured, nor bank guaranteed. § Non-traded REITs are illiquid. If the company does not successfully implement a liquidity event, investors may have to hold an investment for an indeterminate period of time. There is no public trading market for the shares. The company has no obligation to list on any public securities market and does not expect to list the shares in the near future. There is a risk that a stockholder may not be able to sell shares at a time or price acceptable to the stockholder, or at all. § The company's net asset value (or NAV) per share is a valuation of the company's portfolio of properties and debt as of the end of the calendar year and may not necessarily correspond to realizable value upon the sale of such properties. Therefore, the company's estimated NAV per share may not reflect the amount that would be realized upon a sale of each of the company's properties and should not be relied on as the value a shareholder will be able to realize at the time of a liquidity event. § Epidemics, pandemics, or other infectious diseases, and future potential variants, may result in a decline in occupancy, resident fees, and revenues and coupled with an increase in pandemic related operating expenses, could have a negative impact on the company's business, results from operations, financial condition, liquidity and cash flows, which impact will depend on many factors. § The use of leverage to acquire assets may hinder the company's ability to pay distributions, may require partial repayment if the value of assets decline and may decrease the value of stockholders' investment. 7

Risk Factors § There are significant risks associated with the senior housing and healthcare sectors including market risk impacting demand, litigation risk and the cost of being responsive to changing government regulations. Events, including macroeconomic trends such as inflation, which adversely affect the ability of seniors to afford the company's daily resident fees, could cause the occupancy rates, resident fee revenues and results of operations of the company's seniors housing properties to decline. § The company relies on its advisor and the advisor's affiliates to conduct operations. The company is obligated to pay substantial fees to its advisor and its affiliates based upon agreements which have not been negotiated at arm's length. These fees could influence their advice and judgment in performing services. Certain officers and directors of the advisor also serve as the company's officers and directors, as well as officers and directors of competing programs, resulting in conflicts of interest. Those persons could take actions more favorable to other entities than to the company. Additionally, the financial condition of our operators and tenants can impact the company's operating revenue. § The company has paid distributions on a quarterly basis; however, there can be no assurance that the company will be able to achieve expected cash flows necessary to pay or maintain distributions at any particular level or that distributions will continue over time. The amount and basis of distributions are determined by and at the discretion of the board of directors and are dependent upon a number of factors, including but not limited to, expected and actual net operating cash flow, funds from operations, financial condition, capital requirements, needs for cash for capital and other corporate purposes, avoidance of volatility of distributions, and retaining qualification as a REIT for federal income tax purposes. Failure to qualify as a REIT would adversely affect the company's operations and the company's ability to pay distributions to investors. Agreements with the company's lenders may also restrict the company's ability to pay distributions. § Aspects of the company's organizational structure, including the limit on the percentage of shares of the company's stock that any person may own, the ability of the company's board of directors to take certain actions without stockholder approval, and the company's use of an operating partnership structure could have a material adverse effect on the distributions investors receive from the company, could reduce the value of the company's assets needs for cash for capital and other corporate purposes. 8
