CBRE may delegate any of the foregoing duties to any Person so long as CBRE or any Affiliate remains responsible for the performance of such duties.

4. Fees.

(a) IM Consulting Fee. CBRE shall be paid as compensation for the consultation services rendered to the Company hereunder an investment management consulting fee (the “IM Consulting Fee”). The IM Consulting Fee shall be payable in cash.

The IM Consulting Fee shall be calculated monthly in a manner consistent with the calculation of the Investment Management Fee pursuant to the Advisory Agreement, and the IM Consulting Fee calculated with respect to each month shall be payable monthly in arrears within ten days from the end of each calendar month.

- 5 -

notify CBRE of any Property that the Company objects to being included on the list within 10 days of its receipt of the list from CBRE. If the Company objects to any Property’s inclusion on the list, then the parties shall attempt in good faith to promptly resolve such objections. Any Property that the Company does not object to or that, following an objection, the Company agrees is properly included on the list shall be a Qualifying Property.

The Company shall pay CBRE or its Affiliates a Real Estate Commission Fee upon Sale of one or more Properties, in an amount equal to the lesser of (i) one-half of the Competitive Real Estate Commission, or (ii) 3% of the sales price of such Property or Properties. Payment of such fee may be made only if CBRE or its Affiliates provides a substantial amount of services in connection with the Sale of Property or Properties. In addition, the amount paid when added to all other real estate commissions paid to unaffiliated parties in connection with such Sale shall not exceed the lesser of the Competitive Real Estate Commission or an amount equal to 6% of the sales price of such Property or Properties.
