Investors must have either (a) a net worth of at least $350,000 or (b) an annual gross income of at least $100,000 and a minimum net worth of at least $100,000.

------

For purposes of determining whether you satisfy the suitability standards, (i) "net worth" is calculated excluding the value of an investor's home, home furnishings and automobiles; (ii) if not otherwise specified, "liquid net worth" means that portion of an investor's net worth consisting of cash, cash equivalents and readily marketable securities; and (iii) "direct participation programs" means REITs, business development companies, oil and gas programs, equipment leasing programs, and commodity pools, but excludes federal and state exempt private offerings and any investment company registered pursuant to the Investment Company Act of 1940, as amended.

<u>Alabama Investors</u>. A person's aggregate investment in us and other non-traded direct participation programs shall not exceed 10% of the person's liquid net worth at the time of their investment in us. The concentration limit shall not apply to investments made as a result of participation in a distribution reinvestment program. This concentration limit shall not apply to any person that is an accredited investor as defined in Rule 501(a) of Regulation D.

------

The primary responsibility for the management decisions of our advisor and its affiliates, including the selection of investment properties to be recommended to our board of directors, the negotiation for these investments, and asset management decisions, will reside in an investment committee of our sponsor. The investment committee is comprised of James Condon, Erik Rostvold, Bryan Marsh, Chris Flynn and Simon Mitchell. Mr. Condon serves as the Chair of the investment committee. Investment decisions require the approval of a majority of the members of our advisor's investment committee. The high level of interaction between the Investment Committee and investment professionals from the inception of a transaction to closing helps identify potential issues early and enables the team to more effectively streamline resources and workflows. The Investment Committee process emphasizes a consensus-based approach to decision making among the members.

Our board of directors adopted a policy pursuant to which, subject to the terms and conditions of our advisory agreement, our advisor will be authorized to make any and all investments in assets with a contract purchase price less than $1,000,000 without obtaining the prior approval of our board of directors, so long as any such investment would not, if consummated, violate our investment guidelines or any restrictions on indebtedness and the consideration to be paid for such assets does not exceed the fair market value of such assets.

The IRS uses the numbers for identification purposes and to help verify the accuracy of your tax return. The IRS also may provide this information to the Department of Justice for civil and criminal litigation, and to cities, states, the District of Columbia and U.S. possessions to carry out their tax laws. The IRS also may disclose this information to other countries under a tax treaty, to federal and state agencies to enforce federal nontax criminal laws, or to federal law enforcement and intelligence agencies to combat terrorism. You must provide your TIN whether or not you are required to file a tax return. Payers must generally withhold 28% of taxable interest, dividend, and certain other payments to a payee who does not give a TIN to a payer. Certain penalties also may apply. Penalties • Failure to Furnish TIN. If you fail to furnish your correct TIN to a requester, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect. • Civil Penalty for False Information With Respect to Withholding. If you make a false statement with no reasonable basis which results in no backup withholding, you are subject to a $500 penalty. • Criminal Penalty for Falsifying Information. Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment. • Misuse of TINs. If the requester discloses or uses taxpayer identification numbers in violation of Federal law, the payer may be subject to civil and criminal penalties.
