The lease-related expenses are borne evenly in the proportion of the leased space to the total lease area of the economic unit. To the extent that lease-related expenses can be allocated directly, e.g. because individual tenants use certain areas of the building exclusively, they are to be charged to the respective tenants unless it is question of minor expenses.

The Operator has the right, at its reasonable discretion, and even effective for the reporting period in course, to specify a new allocation key for the lease-related expenses (in general or for individual cost categories), if this is appropriate.

The Operator each year will ask the heating contractor Rheinenergie/Brunata commissioned by Lessor to prepare a heating cost statement.

Lessee herewith accepts the respective settlement conditions of the contractor. Settlement is to be effected in the context of the lease-related expense statement due each year.

The Operator must give credit to Lessee for the pre-payments of lease-related expenses accrued during the financial year. In case the lease is terminated in the course of a financial year, the costs are allocated in the next statement in the proportion of the lease period to the reporting period.

3

The financial year is the calendar year. The Operator has the right to change the financial year to another period by advising Lessee unilaterally, and to proceed to a partial settlement in case the property is sold. Over- or underpayments must be settled immediately and mutually. In case the lease-related expenses increase or decrease, the Operator must recalculate the monthly pre-payment amount.

§ 4                   Lump-sum compensation for the use of the recreation and conference rooms

A flat amount of € 0.51 per m2 is charged for the use of the recreation and conference rooms in the Technology Park. The lump-sum compensation for the use of the recreation and conference rooms is to be settled in conjunction with the pre-payments for lease-related expenses.

·  the free use of the conference and recreations rooms rented by the Operator for discussions, conferences and meetings,

The timeliness of the payment is determined not by the date it is sent but by the date it is received.

§ 4.3         In case of late payment the Operator may charge dunning costs in the amount of € 5.00 including VAT per reminder starting from the second reminder.

The same applies to settling the water consumption costs if they are determined by separate meters.
