Any change in the purpose of the lease shall require the express permission of the Lessor, and the Tenant shall enjoy no claim upon such permission. Any alteration in the purpose of the lease undertaken without this permission shall provide the Lessor with grounds for immediate termination of contract.

The keys to the premises shall be handed over at the latest on 16 December 1996. Any delays in handing over shall not entitle the Tenant to raise any claim - especially claims for damages against the Lessor. (2) This Lease is fixed for five years, to commence on the day of handing over, in accordance with Section 1. (3) The Tenant is entitled, by means of a written declaration to be made to the Lessor by registered post at a term of six months before the expiry of the fixed contractual period, to require one extension of the leasehold for a period of a further five years, retaining all contractual agreements. (4) The Leasehold Premises are subject to the Building Specification (Appendix 2 of this Contract), and to the Room Schedule, which is still to be drawn up, but about which the Parties are in agreement as to its essential contents. (5) When the finished Leasehold Premises are handed over, a Memorandum of Transfer shall be drawn up to be signed by both Parties. In this Memorandum the Tenant shall confirm such transfer of the Leasehold Premises. The Tenant may only refuse to take the premises over if essential deficiencies are present, such as to cause major impairment of their agreed purpose. In general the Memorandum of Transfer shall list any deficiencies and final work which the lessor must still undertake. Such work shall be carried out by the lessor within an appropriate time. Moreover the Memorandum of Transfer must contain a measurement of area, which shall form the basis for assessing the rental payment. 3. RENTAL PAYMENT (1) The monthly net rental payment for the premises leased on the Third Floor of Building III shall be DM 19.00 per square meter of net floor area: taking an expected net floor area of approx. 420 square meters, this will therefore be DM 7,980.00 (2) The monthly net rental payment for the 12 leased vehicle parking spaces in the underground garage shall be DM 80.00 per parking lot, amounting to a total therefore of DM 960.00. (3) In addition to the net rental payment stated above, the Tenant shall bear the running costs as set out in Appendix III to Section 27 of the Second Accounting Order of the New Buildings Leasehold Order, which is part of this Contract as Appendix 3. The Parties to this Contract hereby agree that the cost schedule for living accommodation mentioned has been drawn up and must therefore be understood in an extended sense, corresponding to commercial use. Should new public charges be introduced or new running costs arise, the Tenant shall be charged with these in the same way, insofar as this does not exclude statutory regulations. Insofar as these additional overheads to be born by the Tenant are not charged to him directly, an allocation shall be levied. Such a levy will be made for heating and hot water according to consumption, as set out in the hot water order. Insofar as a levy according to consumption or direct levy is not made, a levy shall be made in the proportion which these leasehold premises hold to the total leasehold premises available in the whole Property. In goodwill the Lessor will apportion the charges by a fair calculation in accordance with Section 315 BGB (Federal German Code). Should the Tenancy end during the accounting period, then without the Tenant having any claim to receive an account in advance of the end of the accounting period - an intermediate reading of the measuring equipment shall be carried out. Should an intermediate reading not be carried out, then the charges shall be divided by the Lessor between the Tenant and the subsequent Tenant or the Lessor himself in accordance with a fair calculation. The Tenant shall bear the costs of the administration of the building by way of the apportioned levy. The levy shall be made in the proportion which these leasehold premises hold to the total leasehold premises available in the whole Property. Monthly advance payments will be claimed for the additional charges born by the Tenant amounting to DM 3.00 per square meter of area occupied. The monthly advance payments are payable together with the rent. Subsidiary charges shall be accounted annually by 30 Subsidiary charges shall be accounted annually by 30 June of the following year. The accounted sum is payable within two weeks after receipt of the invoice. The Lessor is entitled - and, at the request of the Tenant shall have the duty - to adjust the advance payments to the probable trend of the subsidiary charges themselves. An adjustment shall take place in any case to the balance of the previous year. (4) In addition to rental payment and subsidiary charges the Tenant shall pay the turnover tax levied upon them at the rate in statutory force for the time being. (5) The probable monthly rent will amount to: Office Premises DM 7,980.00 Vehicle parking spaces in underground garage DM 960.00 Advance subsidiary charges DM 1,260.00 Turnover tax (currently 15%) DM 1,530.00 Total DM 11,730.00 The rental payment, the advance payment for subsidiary charges, and the turnover tax levied on these shall be payable in advance by the fifth calendar day of every month and shall be transferred free of charge to Account Number 915 515 5 of the Nationalbank AG, Mulheim an der Ruhr (Bank Sorting Code 362 200 30). In the case of delay the Tenant shall be liable to additional late payment charges of at least 6% above the current discount rate of the German Federal Bank. Ingoing payments which fail to repay all the Lessor's unpaid demands shall be applied firstly to the interest, then to the subsidiary charges (firstly to the earlier, then to the later), and lastly to the basic rent (firstly to the earlier, then to the later), even if the Tenant has directed a different repayment. (6) The rental is further assured as follows: If the index of prices for average cost of living according to the Federal Office of Statistics, Wiesbaden, (households of four people consisting of workers and employed persons with a middle-range income, basis: 1985 = 100) changes by 10% or more up or down compared to its state when the Leasehold Premises were handed over to the tenant, or compared to its state when it formed the basis of the last adjustment, the rental shall alter accordingly. Such information shall be based on the monthly publications of the currently continuing index of the Federal Office of Statistics, Wiesbaden. The rental payment shall alter at the same time as the index prices for the average cost of living alters. In the case of a rise the Lessor, in the case of a fall the Tenant shall give notice of the change and present an account. If notice is not given, or not given in time, this shall not be taken to mean that the claim for adjustment has been abrogated. The amended rental shall be paid retrospectively; any difference shall be reimbursed retrospectively; however, the Contracting Parties shall hereby be deemed to be in arrears only after the relevant account has been presented and only after a proper term of notice has expired. Should the Federal Office of Statistics cease to continue the agreed price index wholly or in part, then a subsequent index of a suitable kind shall be used in its place, or an index which guarantees the value of the rental to the same extent as the original regulatory index, such guaranty being the intention of the Parties. The above value-assurance stipulation requires the approval of the competent State Central Bank, which the Lessor shall obtain. Should this approval be refused, or should the agreed value- assurance stipulation be invalid for any other reason, then its place shall be taken by a regulation which in its financial import shall approach the intention of the agreed value assurance stipulation as nearly as possible. 4. DECORATIVE REPAIR, BUILDING ALTERATIONS, LIABILITY (1) All decorative repair in the premises shall be undertaken by the Tenant at his own expense during the term of the Lease.

At the termination of the Lease the Tenant shall undertake all decorative repair completely. Decorative repair must be carried out in a professional manner. Should the Tenant fail to fulfill his obligations, then the Lessor, assuming that he has made requirement of the Tenant to carry out such work without result, may demand reimbursement of the costs attendant on carrying out the work. (2) Minor repairs over and beyond the Lessor's duty of guaranty up to the sum of DM 500.00 in each case shall be born by the Tenant, but not more than DM 3,000.00 per year of the Lease.
