Re: Dearborn Site - Management Agreement

Dear Charles:

            This letter outlines the services and fees for managing the site
located at Dearborn, State and Adams. We are confident that you and your firm
will protect our interest in Chicago while we formulate a strategy for the site.

Services and Term

o     Ensure that contracts are in place to maintain the property's appearance
      and condition, including landscaping, fence maintenance, rodent control,
      trash removal and weed control. Prior to each contract's expiration,
      evaluate the service provider, and renew/relet the contract for one year
      with a 30 day cancellation provision. Please coordinate with Richard
      Ellis, Inc. to obtain current contracts, and provide a summary of
      contractors and contract terms currently in place. Any and all contracts
      and expenditures will be signed or approved by DIHC Management Inc. if
      they exceed $3,000.00 in any one year.

o     Ensure that invoices from contractors are accurate, then submit to DIHC
      Management Corporation for payment. We will pay the service providers
      directly on a monthly basis when we make our management fee payment to
      Concord Realty Advisors Inc.

      of pocket expenses paid upon receipt and review of the monthly report (due
      on the 10th). This fee will be prorated for any partial month in the term.
