Companys Properties, plus the net asset value of all other Loans and Permitted Investments of the Company plus total Distributions (excluding any stock dividend) through the Termination Date exceeds (b) the sum of Invested Capital plus
total Distributions required to be made to the stockholders in order to pay the Stockholders 8% Return from inception through the Termination Date less (2) any prior payment to the Advisor of a Subordinated Share of Cash Flows. Interest
on the Performance Fee Note will accrue beginning on the Termination Date at a rate deemed fair and reasonable by the Conflicts Committee. The Company shall repay the Performance Fee Note at such time as the Company completes the first Sale after

years from the Termination Date, then the Advisor, its successors or assigns, may elect to convert the balance of the fee, including accrued but unpaid interest, into Shares at a price per Share equal to the average closing price of the Shares over

such Property. With respect to the acquisition of real property through any Joint Venture or partnership in which the Company is a co-venturer or partner, the Acquisition Fee payable to the Advisor shall

the Contract Sales Price; provided, however, that no Disposition Fee shall be payable to the Advisor for any Sale if such Sale involves the Company selling all or substantially all of its Properties in one or more transactions designed to effectuate
a business combination transaction (as opposed to a Company liquidation, in which case the Disposition Fee would be payable if the Advisor or an Affiliate provides a substantial amount of services as provided above). Any Disposition Fee payable

Following Listing, no Subordinated Share of Cash Flows will be paid to the Advisor.

8.05 Subordinated Incentive Fee. Upon Listing, the Advisor shall be entitled to the Subordinated Incentive Fee in an amount equal to 15.0% of the amount

with such period beginning 180 days after Listing (the Market Value), plus the total of all Distributions paid to Stockholders (excluding any stock dividends) from the Companys inception until the date that Market Value is
determined, exceeds (ii) the sum of (A) 100% of Invested Capital and (B) the total Distributions required to be paid to the Stockholders in order to pay the Stockholders 8% Return from inception through the date Market Value is
determined. The Company shall have the option to pay such fee in the form of cash, Shares, a promissory note or any combination of the foregoing. The Subordinated Incentive Fee will be reduced by the amount of any prior payment to the Advisor of a
Subordinated Share of Cash Flows. In the event the Subordinated Incentive Fee is paid to the Advisor following Listing, no other performance fee will be paid to the Advisor.

the Advisor, be susceptible of indication of some form of relationship between the Company and the Advisor or any its Affiliates. At such time, the Company will also make any changes to any trademarks, servicemarks or other marks necessary to remove
