Risk Factors
An investment in shares of Senior Common Stock involves substantial risks. You should purchase our securities only if you can afford a complete loss of your investment. Please read and consider the risk factors in the prospectus supplement and prospectus before purchasing any securities. The most significant risk factors include:
Risks Relating to Our Senior Common Stock and this Offering:
There is no established public trading market for shares of Senior Common Stock, and we have no plans to list these shares on a national securities exchange.
?We established the offering price of shares of Senior Common Stock on an arbitrary basis, and, as a result, the actual value of your investment may be substantially less than what you pay.
?The calculation of the Exchange Ratio could result in a deterrent to your exchanging shares of Senior Common Stock for shares of Listed Common Stock if shares of Listed Common Stock are trading at lower levels at the time that you desire to exchange your shares.
?Your ability to redeem shares of Senior Common Stock pursuant to our share redemption program is limited to the proceeds generated by our distribution reinvestment plan, and the share redemption program may be amended, suspended or terminated by our Board at any time without stockholder approval.
?If you do not agree with the decisions of our Board, then you will not be able to influence changes in our policies and operations because holders of shares of Senior Common Stock will generally have no voting rights.
?Our charter contains restrictions on the ownership and transfer of shares of our capital stock, and these restrictions may inhibit your ability to sell your shares of Senior Common Stock promptly, or at all.
?Our Dealer Manager is one of our affiliates, and, therefore, an investor in shares of Senior Common Stock would not have the benefit of an independent underwriter who has performed an independent due diligence review.
?Highly leveraged tenants and borrowers may be unable to pay rent or make mortgage payments, which could adversely affect our cash available to make distributions to holders of our Senior Common Stock.

Risk Factors (continued)
Risks Relating to Our Company and Our Operations
?Our business strategy relies heavily on external financing, which may expose us to risks associated with leverage such as restrictions on additional borrowing and payment of distributions to stockholders, risks associated with balloon payments, and risk of loss of our equity upon foreclosure.
?We are subject to certain risks associated with real estate ownership and lending which could reduce the value of our investments, including but not limited to, changes in the general economic climate; changes in local conditions such as an oversupply of space or reduction in demand for real estate; changes in interest rates and the availability of financing; competition from other available space; and changes in laws and governmental regulations, including those governing real estate usage, zoning and taxes.
?Our properties may be subject to impairment charges, which could adversely affect our results of operations.
?Illiquidity of real estate investments may make it difficult for us to sell properties in response to market conditions and our properties may include special use and single or multi-tenant properties that may be difficult to sell or re-lease upon tenant defaults or early lease terminations which could harm our financial condition and ability to make distributions.
?Our real estate investments have a limited number of tenants, many of which are small- and medium-sized businesses, and are concentrated in a limited number of industries, which subjects us to an increased risk of significant loss if any one of these tenants is unable to pay or if particular industries experience downturns.
4

Risk Factors (continued) Risks Relating to Our Company and Our Operations (continued from previous slide)
?We may be unable to renew leases, lease vacant space or re-lease space as leases expire, which could adversely affect our business and our ability to make distributions to our stockholders.
?We may enter into sale-leaseback transactions, whereby we would purchase a property and then lease the same property back to the person from whom we purchased it. If a sale-leaseback transaction is re-characterized in a tenant’s bankruptcy proceeding, our financial condition could be adversely affected.
?We are dependent upon our key management personnel, who are employed by our Adviser, for our future success, particularly David Gladstone, Terry Lee Brubaker, and Robert Cutlip.
?Our success depends on the performance of our Adviser and if our Adviser makes inadvisable investment or management decisions, our operations could be materially adversely impacted.
?We may have conflicts of interest with our Adviser and other affiliates, including but not limited to the following conflicts: (i) our Adviser may realize substantial compensation on account of its activities on our behalf, and may, therefore, be motivated to approve acquisitions solely on the basis of increasing compensation to itself; (ii) we may experience competition with our affiliates for financing transactions; (iii) our Adviser may earn fee income from our borrowers or tenants; and (iv) our Adviser and other affiliates could compete for the time and services of our officers and directors.
?If we fail to qualify as a REIT, our operations and dividends to stockholders would be adversely impacted.
?To the extent that our distributions represent a return of capital for tax purposes, you could recognize an increased capital gain upon a subsequent sale of your stock.
