Forward-looking statements The presentation materials contain forward-looking statements within the meaning of Private Securities Litigation Reform Act, and we intend that these forward-looking statements be subject to the safe harbors created thereby. These forward-looking statements are not historical facts, but rather are predictions and generally can be identified by use of statements that include phrases such as "believe," "expect," "anticipate," "estimate," "intend," "plan," "foresee," "looking ahead," "is confident," "should be," "will," "predicted," "likely" or other words or phrases of similar import. Similarly, statements that describe or contain information related to matters such as our intent, belief or expectation with respect to our financial performance, investment strategy and portfolio, cash flows, growth prospects and distribution rates and amounts are forward-looking statements. These forward-looking statements often reflect a number of assumptions and involve known and unknown risks, uncertainties and other factors that could cause our actual results to differ materially from those currently anticipated in these forward-looking statements. In light of these risks and uncertainties, the forward- looking events might or might not occur, which may affect the accuracy of forward-looking statements and cause our actual results to be materially different from any future results expressed or implied by such forward-looking statements. Certain factors that could cause actual results to differ materially from these forward-looking statements are listed from time to time in our filings with the Securities and Exchange Commission reports, including, but not limited to, the Annual Report on Form 10-K for the fiscal year ended December 31, 2008 and include but are not limited to the following: No public market exists for our common stock and therefore it will be difficult for stockholders to sell their shares. If stockholders are able to sell their shares, they would likely have to sell them at a substantial discount. Current dislocations in the credit markets and real estate markets could have a material adverse effect on our results of operations, financial condition and ability to pay distributions to stockholders. We have purchased a limited number of properties and have not identified most of the properties or other real estate related assets we plan to acquire with the proceeds from this offering. As a result, you will not be able to evaluate the economic merits of the investments we will make from the proceeds from this offering prior to purchasing shares.

Forward-looking statements Our ability to effectively manage our company with our internal management team will significantly impact our ability to achieve our investment objectives. Our success depends to a significant degree upon the continued contributions of certain key personnel, each of whom would be difficult to replace. If we were to lose the benefit of the experience, efforts and abilities of one or more of these individuals, our operating results could suffer. We have a limited operating history and there is no assurance we will be able to achieve our investment objectives. Distributions we pay to our stockholders may include a return of capital, which will lower their tax basis in our shares. We have paid distributions from sources other than our cash flow from operations, including from the proceeds of this offering or from borrowed funds; if we pay future distributions from sources other than our cash flow from operations, we will have fewer funds for real estate investments and your overall return may be reduced. We historically have relied on our advisor and its affiliates for our day-to-day operations and the selection of our investments. We pay substantial fees to our advisor and its affiliates for these services and the agreements relating to their compensation were not reached through arm's-length negotiations. There are limitations on the ownership, transferability and redemption of our shares which significantly limit the liquidity of an investment in shares of our common stock. If we do not qualify as a REIT, it would adversely affect our operations and our ability to make distributions to our stockholders. We disclaim any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise. This presentation is neither an offer to sell or the solicitation of an offer to buy any security, which can only be made by the prospectus, which has been filed or registered with appropriate state and federal regulatory agencies.

Projected National Health Expenditures Source: U.S. Department of Health and Human Services, Centers for Medicare and Medicaid Services, Office of the Actuary, "National Health Expenditures and Selected Economic Indicators, Levels and Annual Percent Change: Calendar Years 2003-2018." Projections are inherently subject to uncertainty. These projections are estimated based on historical trends and relationships in health spending; any structural break in these relationships is generally unpredictable. These projections also rely on assumptions about macroeconomic conditions and health sector parameters and their relationship to health care spending, with the degree of uncertainty increasing along with the projection horizon. 16
