Under the advisory agreement, the Advisor and its affiliates have the right to seek reimbursement from us for all costs and expenses they incur in connection with their provision of services to us, including our allocable share of the Advisor’s overhead, such as rent, employee costs, utilities, accounting software and cybersecurity costs. We reimburse the Advisor for our allocable portion of the salaries, benefits and overhead of internal audit department personnel providing services to us. In the future, the Advisor may seek reimbursement for additional employee costs. However, we will not reimburse the Advisor or its affiliates for employee costs in connection with services for which the Advisor earns acquisition, origination or disposition fees (other than reimbursement of travel and communication expenses) or for the salaries and benefits the Advisor or its affiliates may pay to our executive officers.

For substantial assistance in connection with the sale of properties or other investments, we pay the Advisor or its affiliates 1.0% of the contract sales price of each property or other investment sold; provided, however, in no event may aggregate disposition fees paid to the Advisor, its affiliates and unaffiliated third parties exceed 6.0% of the contract sales price.

Our Relationship with the Dealer Manager.
