Part I

Special terms of contract

2

1. Object of the lease

1.1     The following premises and parking bays located in the Bensberg-Honschaft property and outlined in red in the attached floor plan Part I, (Annex No. 1), are leased for use as a manufacturing and engineering business:

The agreed upon leased surface area is as follows:

The above surface areas include adjacent and traffic areas.

1.2     If deviations from the listed leased surface areas should be encountered in case of subsequent measurements of the leased surface areas, neither of the parties is entitled to withdraw from the present Contract, to terminate it or to demand a change in rent because of this. The surface areas listed under Paragraph 1.1 shall constitute the basis for the provisions of this Contract concerning the size of the leased property.

1.3     The exterior surface areas of the premises are not leased.

3

1.4     If an official permit that is necessary for the implementation of the use recorded in Paragraph 1.1 is refused or recalled because the location or configuration of the leased premises is not suitable for the operation, the Tenant has the right to cancel [the Contract] without notice or to demand a reduction [in rent]. Liability under a guarantee per 536a BGB [German Civil Law Code] is barred. The Landlord is furthermore not obligated to re-arrange the leased premises into a licensable condition if this involves unreasonable expenses.

1.5     Future official and technical requirements (e.g. tightened safety or health regulations; a change in use), concerning the Tenant’s operation shall be implemented by the Tenant at its own expense and must exempt the Landlord from any claims that may arise against the Landlord. If such requirements should not be satisfied, the Tenant shall have no right to demand compensation from the Landlord, to give notice, to withdraw or to refuse payment of damages or rights to refuse payment. The Landlord is obligated to cooperate in the fulfillment of the requirements, as long as the Tenant also assumes the respective costs.

2. Transfer

2.1     The transfer of the leased premises to the Tenant is bindingly specified in advance by both sides. The claim for transfer of the rented premises arises only upon receipt of the security payment pursuant to Paragraph 6.

2.2     If the Tenant, for whatever reason, does not appear on the transfer date communicated in writing, wrongly rejects the transfer or the landlord has not received the security deposit, the Tenant authorizes the Landlord to determine the readiness of the leased property for transfer in its name according to the Landlord’s obligatory discretion. The Landlord is then obligated to promptly submit a copy of the transcript concerning the readiness for transfer to the Tenant. The Landlord is, to this extent, exempt from the restrictions of § 181 of the BGB.

2.3     A transcript of transfer, which must be signed by the Landlord and the Tenant and in which all evident deficiencies and complaints that are still to be corrected by the Landlord are listed, must be prepared when the leased property is transferred. The Landlord shall immediately correct any deficiencies that are detected.

2.4     Any minor deficiencies and work still to be performed after the transfer, which only slightly impair the use of the property, shall not delay the transfer. This also applies to outside facilities.

2.5     The Tenant, is entitled to bring built-in components, renter’s installations, technical devices or the like into the leased premises at its own risk, if this does not significantly interfere with or obstruct the work being performed by the Landlord.

3. Term of the lease / cancellation

3.1     The tenancy begins on 04/01/009, but not before the completion and transfer of the leased property, and is firmly completed on 12/31/2010. The Tenant has the optional right to request an extension of 3× 5 years. The option must be exercised toward the landlord in writing at the latest 12 months before the respective expiration of the Contract.

The parties are in agreement concerning the fact that, upon exercise of the respective option, the tenancy shall continue under the same conditions.

If an option is not effectively exercised, further option rights that may have been agreed upon for the future regarding a respective part of the leased property shall not apply.

4

3.2     If the option is not exercised or if the tenancy or the partial tenancy expires after the option is exercised, the tenancy shall extend for an indefinite period of time and can then be terminated in writing by either of the Contracting Parties by complying with a term of notice of 6 months before the end of the quarter.

3.3     The timeliness of the extension declaration or the notice which is to be rendered in writing does not depend on the mailing date, but rather on the receipt of the letter.

3.4     The Landlord can terminate the tenancy for an important reason with immediate effect, without abiding by a term of notice. This applies particularly if, despite a written warning, the Tenant does not comply with its essential contractual obligations within an appropriate period of time or if bankruptcy or settlement proceedings are initiated concerning its property or if the commencement is rejected for lack of assets. Further rights of the Landlord concerning cancellation of the tenancy without notice based on legal provisions remain unaffected.

3.5     In case of a justifiable immediate premature notice or upon termination of the tenancy without notice, the Tenant is, to the extent that it is accountable for this, liable for the resulting loss of rent, additional expenses and other payments for the contractually agreed upon duration of the tenancy up to the next permissible contractual termination date.

3.6     If the Tenant continues to make use of the tenancy after the expiration of the lease, then, contrary to § 545 of the BGB, the tenancy shall not be considered as having been extended.

3.7     If it should be entirely or partially impossible to make use of the leased property because of damage that is not attributable to the Tenant, then rent payments for the unusable parts shall be suspended for the duration. The rent payments shall resume immediately after restoration. If the leased area and/or leased rooms or any communal facilities are wholly or predominantly destroyed or damaged because of constructional defects, fire, explosion, lightning, storms, force majeure, the effects of war or other events, without this being attributable to the Landlord, the Tenant shall have an extraordinary right to give notice. This right can be only exercised within 6 months after the damage has occurred.

4. Rent, additional costs and value added tax

4.1     The monthly rent for the leased property per Paragraph 1.1 as of the point in time per Paragraph 3.1 is:

5

4.2     Not applicable

4.3     Not applicable

4.4     Not applicable

4.5     The rent shall be remitted monthly in advance at the latest by the 3rd working day of the month postage paid and free of charges, with specification of the Tenant No. - to the Landlord’s account at

Lobito International B.V.

at the Dresdner Bank Frankfurt

Account number: 958 293 01

Bank code number: 500 800 00.

The timeliness of the payment is determined by its receipt, not its mailing date.

4.6     In case of late payment, the Landlord can demand reminder costs as of the 2nd reminder, at a value of EUR 2.50 including VAT for each reminder. It can furthermore charge interest at the rate of 4% percentage points above the respective base interest rate (§ 247 of the BGB).

4.7     If the Tenant makes partial payments on its liabilities, the Landlord may, if it so chooses, perform an accounting of bills receivable regardless of the information supplied by the Tenant.

4.8     The Landlord is only responsible for the immaculate transfer of use of the leased property. All supplementary services are furnished by a company commissioned by the Landlord (at present the Technology Park

6

Bergisch Gladbach Administration GmbH). This company also bills for the heating and operating costs and supplementary payments (additional expenses) for which the Tenant is responsible in addition to the basic rent.

The Tenant is, for this reason, obligated to also conclude the attached operator’s contract (Annex) with the company charged by the Landlord with the administration of the leased property and to abide by it for the duration of the present Contract.

5. Indexing agreement

5.1     The rent applies as agreed upon until 12/31/2010. Thereafter, the rent is subject to the currently applicable indexing:

The Landlord and the Tenant are entitled to request an adjustment of the rent agreed upon in Paragraphs 4.1 and 4.2, if the price index for the overall living standard (base year 2005 = 100 points) as determined by the Federal Statistical Office has risen or fallen by more than 10% since the start date of the Contract and/or the last respective reassessment of the rent. The adjustment of the rent per Paragraph 1 occurs at a rate of 80% of the change in the index, namely as of the end of the month following the justified demand for an adjustment by one of the parties.

5.2     If the aforementioned index is no longer maintained by the Federal Statistical Office or is changed over to another base number, then the indexing shall be based on that index which corresponds as much as possible to the cost of living index agreed upon here.

6. Security deposit

The Tenant shall remit a security deposit of 20,000 € to the Landlord one month before the transfer of the leased property.

The Tenant is entitled to provide an absolute guarantee by a German bank or savings bank in the aforesaid amount instead of a cash security deposit. The absolute guarantee document must contain a guarantee that the guarantor will pay the guaranteed sum upon the first written request. The guarantor can only exempt itself from its obligation by payment, not by escrow.

In the case of payments due during the current tenancy, the Landlord is entitled to satisfy its demands in advance by drawing on the security deposit. In this case, the Tenant must replenish the security deposit at an appropriate amount.

The security deposit shall be returned after dissolution of the tenancy and fulfilment of the contractual obligations. In case of non-fulfillment of the Contract, only to the extent than no counterclaims exist.

7. Competition / product mix protection

The Landlord promises to lease to other tenants within the technology park, who are in the same business as the Tenant according to the trade register, only upon prior agreement by the Tenant. The purpose of the business is the development, production and sale of electromagnetic and other components and systems for particle accelerator facilities and other applications in science (such as high-energy physics, applied research), energy technology (such as nuclear fusion and fission), medicine (such as radiotherapy) as well as the high technology industry.

7

8. Further agreements

The Landlord is aware that the Tenant occasionally operates with 3 shifts as well as on weekends, except for holidays.

The Landlord promises to provide for the use of the leased property, in particular regarding the provision of heat, power, water, etc., as well as unhindered access to the leased property. Paragraphs 3.1 and 3.2 of the general contractual provisions do not apply to that extent. If a provision has been agreed upon in the special contractual provisions, it shall take precedence in case of conflict with a provision of the general contractual provisions.

To the extent that responsibilities for maintenance and repair are not expressly assumed by the Tenant according to the present Contract, these are the Landlord’s responsibility, regardless of their associated costs, unless the Tenant declares itself to be willing to perform these maintenance or repair tasks by itself or to have them performed.

The Tenant shall perform maintenance and repair work professionally. It is also entitled to hire appropriately specialized companies to accomplish this in coordination with the Landlord. In the case of actions that have a substantial affect on the leased property, the Tenant shall come to a foregoing agreement with the Landlord. Paragraph 11.3, last section of the general contractual provisions does not apply to this extent.

Upon completion of the term of the lease, the Tenant shall leave the leased property in the condition in which it was upon transfer. The usual wear is to be taken into consideration in favor of the Tenant. Paragraph 20 of the general contractual provisions do not apply to that extent.

The Landlord shall ensure that the STVO [Road Traffic Regulations] apply in the area of the technology park.

9. Special agreements

1. Maintenances:

Sums below 500 € are listed as operating costs in the additional expenses accounting, even if they involve individually attributable sums.

2. Term / notice:

The Contracting Parties agree upon a special right to give notice of 6 months before the end of the quarter for at most 40% of the surface areas that are leased.

3.     Declaration of exemption:

Should the competent authorities, on the basis of enforceable notices, make claims against the Tenant as the holder of physical custody and control per §4, Sec. 2, of the BBodSchG [Federal Soil Protection Act] or for actions against harmful changes in soil conditions per § 4, Sec. 3, of the BBodSchG threatened by the leased property, the Landlord exempts the Tenant from all financial obligations and necessary expenditures arising for the Tenant therefrom. The tenant must forward official notices, on whose basis it is involved as a holder of physical custody and control per § 4, Sec. 2, or § 4, Sec. 3, of the BBodSchG, to the Landlord in a timely manner, at the latest 14 days after receipt, and must submit an appeal upon the latter’s legal assessment and the latter’s appropriate request. To the extent that the landlord insists on appeal proceedings, it shall bear the cost arising therefrom. The Tenant’s claim per Paragraph 1 is excluded, if it does not fulfill its obligations per Paragraph 2. The exemption by the Landlord per Paragraph 1 is likewise excluded if the Tenant himself is the causer of a harmful soil change or if harmful soil changes are threatened by the Tenant’s actions and/or the tenant has taken actions which can lead to a harmful soil change. The Landlord’s claim to compensation per § 24, Sec. 2, of the BBodSchG remains unaffected thereby in all other respects.

4. Exchange of area:

The Tenant is entitled to an exchange of area (of the same size) within Bergisch Gladbach Technology Park.

1. Reconstruction, insurance

1.1       The Landlord promises to contract sufficient insurance (original value insurance) against risks due to fire, tap water and storm damage. The insurance premiums which are to be paid for this are charged to the Tenant in accordance with the agreements under Paragraph 4.8 of the special contractual conditions. The Landlord furthermore promises to employ all insurance payments for the immediate restoration of the damaged parts of a building. Any additional costs and fire insurance premiums due to an increase in risk because of the Tenant’s activities must also be borne by the latter.

11

1.2       The Tenant must procure insurance for the contents of the building (installations and merchandise) at its own expense. The Tenant furthermore assumes the risk for glass breakage of the (showcase) windows belonging to its leased property. The Tenant is obligated, to procure comprehensive general liability insurance, to maintain it and prove an appropriate level of insurance protection upon the Landlord’s request. Any obligation of the Landlord to reimburse for damages is void to that extent.

2. Damage by fire, storm or tap water

The Tenant, must immediately inform the Landlord of damage, concerning insured risks, so that the latter can transmit the notice of damage to the insurance company in time. Disadvantages, which arise because the Tenant did not promptly inform the Landlord of the damage, are debited to the Tenant.

3. Central heating, air conditioning, warm water consumption, consumption recording

3.1       The Landlord is obligated to keep the central heating on during the usual working hours if the outside temperatures so require. Air circulating devices — if available - are operated all year round.

3.2       Warm water, to the extent that it is provided via the central heating station, must be supplied constantly during the usual working hours.

3.3       Heating and/or air conditioning cannot be demanded in case of breakdown, force majeure, official directives or in case of other situations in which it is impossible to supply such services (e.g. fuel scarceness). In these cases, the Landlord is not obligated to supply replacement heating. The Tenant is not entitled to claims for rent reduction and/or claims for damages, unless the Landlord has acted deliberately or with gross negligence. The Landlord must provide for the prompt elimination of any breakdowns.

3.4       The costs of operating the central heating system include the costs of consumed power and its supply and/or the off-site heating purchased, the cost of the operating current, the costs of the operation, monitoring and care of the equipment, the regular testing of its operational readiness and operating reliability, including adjustment by a specialist, the cleaning of the equipment, including cleaning of the oil tank and the operating room, the costs of measurements per the Federal Emissions Law, the costs of rental or of other kinds of cession of the right to use equipment for measuring consumption, as well as the costs of the use of equipment for recording consumption, the costs of computation and allocation by a heating cost distribution service (including meter readings and periodic meter readings) as well as incurred calibration fees. This [also] applies in general to the determination of the costs of water consumption, if this cost is determined by means of separate measuring instruments. The costs of the supply of off-site heating include the cost of operating the associated in-house equipment as described above.

12

3.5       To the extent that the heating and/or warm water costs are determined separately for the property leased by the Tenant by means of house gas meters or other measuring devices, this firstly comprises 30% of the total cost incurred by the property on the basis of m2 / leased area (basic costs). The Tenant shall bear the costs resulting therefrom according to the individually ascertainable consumption. For separate measurements of cold water consumption, the Tenant shall bear 100% of the individual consumption costs. This applies similarly to sewer use fees.

3.6       If heating elements are installed in common rooms (e.g. stairways, laundry, etc.), which are heated by a common heating system, these are exempted from consumption metering, with the consequence that the costs incurred thereby are included in the total costs that are allotted according to Paragraph 3.5.

3.7       If a Tenant does not make use of the heating system, this does not exempt the tenant from its obligation to participate in these costs.

3.8       The affected Tenant shall bear the cost of a necessary intermediate meter reading.

3.9       The Tenant is obligated to always keep the consumption meter and other measuring devices accessible. If a reading is obstructed or thwarted by the Tenant, it shall reimburse the Landlord for the additional costs or other disadvantages arising therefrom.

4. Use of the elevators

The Tenant is not entitled to demand continuous service, if interruptions in operation occur. The elevators are not serviced. Interruptions in operation must be immediately communicated to the Landlord or its assignee.

5. Set-offs, reimbursement

The Tenant can only demand set-offs against rent and other payments due the Landlord for undisputed, immediately ready for decision or legally established claims, if it has informed the Landlord of its intent in writing at least one month before the due date of the rent. The Tenant’s obligation to inform in writing also applies if it wants to assert a right of retention.

6. Use of the leased property, subletting

6.1       The Tenant may only use the object of the tenancy for the purposes specified in Paragraph 1.1 of the contractual provisions. Any change in use, in particular any change in the nature of the business, is only permissible after prior written agreement by the Landlord. The Landlord does not assume any liability for the fact that permission for the intended operation and its facilities has been granted and/or that permission will continue to be granted. This applies in particular to licenses. The Tenant shall procure and/or abide by all requirements for operating its business at its own expense.

13

6.2       The sale of the Tenant’s entire business or of parts of its business requires prior agreement because of the transfer of this lease to the legal successor of the Tenant.

For companies, a change of the owner and/or the personally responsible proprietor or a changes of a majority stockholder (more than 50%) or a change in the form of the company applies as a cession of use to a third party.

The Landlord may only refuse permission for significant reasons. A significant reason for a refusal to agree is present, for example, if such changes lead to a substantial impairment of the basis of liability.

6.3       Subletting or other cession of use to third parties may also only occur with prior written permission by the Landlord and only for the commercial purposes specified in Paragraph 1.1 of the special contractual conditions. The Landlord may only refuse permission for significant reasons. If the Tenant is obligated per the contract to pay the value added tax in addition to the rent and additional expenses, a sublease or other cession of the right to use may only be granted to third parties who are businesses in the sense of the value added tax code. The Tenant must request such permission in writing from the Landlord and, as long as this concerns a change or an alteration of the type described in Item 2 of Paragraph 6.2 apply for same upon production of the sublease that was concluded according to the stipulation that is to be suspended. The Tenant promises in advance to pay the Landlord 50% of any possibly obtained excess in proceeds for rent and additional expenses along with the remaining monthly rent.

If the Tenant neglects to obtain the Landlord’s written permission, this shall constitute a reason for the Landlord to cancel the tenancy without notice.

6.4       In the event of a sublease or cession of the right to use, the Tenant is liable for all actions or omissions of the subtenant or of the entity to which it has ceded the use of the leased property.

7. Impact of third parties

The external impact of third parties, such as e.g. traffic diversion or the like, shall not constitute a flaw of the leased property regardless of its extent, if the Landlord is not accountable therefore.

8. Electricity, gas, water, heating power

8.1       The Tenant may only make use of the existing power grid for electricity - including possibly available mail and antenna wiring, gas and water to the extent that no overloading occurs. The Tenant can cover an increase in demand by an expansion of the supply at its own expense and after prior consent by the Landlord. The relocation of all other power mains within the leased property and the building also requires the Landlord’s consent.

8.2       In case of disruption or damage to the supply lines, the Tenant must make sure that the power is turned off and that the Landlord is informed. If there is danger in delaying, the Tenant must

14

promptly make sure that the immediate danger is eliminated. The Landlord shall cause any further damage to be eliminated, insofar as maintenance and repair are not incumbent upon the Tenant according to the present Contract. If the latter is not the case, then the Landlord shall also bear the cost of the direct elimination of the hazard.

8.3       A change in suppled power, in particular a change in voltage, does not entitle the Tenant to raise claims for compensation against the Landlord.

8.4       If the electricity, gas or water supply or drainage is interrupted by circumstances that are not attributable to the Landlord, irregularities in the supply or inundations and other disasters occur, the Tenant is not entitled to a reduction in rent and to assert claims against the Landlord. This applies analogously to the heating power supply, if the utility provider is responsible.

To that extent that the supply conditions of the utility provider from which the Landlord obtains power or water allow for responsibility for interruptions in supply, and in case of irregularities in supply, the Landlord hereby surrenders its rights to assert claims against the utility provider to the Tenant, who herewith accepts them. The Tenant shall only assert claims exceeding this, if they can also be asserted by the Landlord.

9. Duty to safeguard the property against hazards

The Tenant shall be responsible for safeguarding the leased property against hazards. The Tenant exempts the Landlord from the claims of third parties to that extent.

10. Advertising acitvities, alarm installations, antenna systems

10.1     If collective signboards are present or provided, the Tenant is obligated to use them and to bear the proportionate cost. Other devices, which serve advertising purposes, may only be installed on the exterior surfaces of the building and the interior or exterior surfaces of windows with the Landlord’s express agreement. The associated costs, including possible permit fees shall be borne by the Tenant.

10.2     If the Landlord intends to recondition, change or repair the surfaces or facilities provided to the Tenant for purposes of mounting advertising installations, the Tenant shall be obligated to remove its advertising installations at personal expense, to store them and to re-attach them after the work is completed.

10.3     It is the Tenant’s responsibility to obtain official permission for advertising media approved by the Landlord. The Landlord shall participate therein to the extent required by law.

The Tenant commits to the proper production, mounting and repair of the advertising device. It shall also be responsible for ensuring the necessary stability. The Tenant shall be liable for personal and property damage incurred by third parties because of these installations. To the extent that it is unavoidably necessary to penetrate a building for purposes of installing advertising

15

media and for purposes of electrical wiring, the Tenant shall be liable for damage caused by humidity entering in the area where the building has been penetrated.

10.4     The Tenant must immediately eliminate any damage to the building caused by mounting, use and maintenance of an advertising installation at its own expense.

10.5     The advertising installations installed by the Tenant must be removed after the tenancy has been terminated and the original condition must be restored at the Tenant’s expense.

10.6     The agreements under the preceding paragraphs apply in a general manner to air conditioners, alarm and antenna systems, to the extent that they are also installed by the Tenant at other locations in the Building. They furthermore apply to sales and advertising installations that are installed at other locations in the building or whose spaces or surfaces are leased separately (vending machines, display cases, advertising slogans, company trademarks, name plates, etc.).

11. Maintenance and repair, cosmetic repairs

11.1     The Landlord shall be responsible for structural maintenance and repair at its own expense (windows and doors, see Paragraph 11.3.).

11.2     The Tenant shall perform cosmetic repairs (e.g. papering, painting of walls and ceilings, painting of the heating elements including heating pipes, the inner doors as well as windows and outside doors from the inside, adequate and professional care of the flooring, etc..)

11.3     The Tenant shall furthermore be responsible for maintenance and repairs within the leased premises at its own expense. This also applies to the technical installations (in particular electrical and sanitary, heating and air conditioning installations), to the extent that they are located in or on the leased premises and are exclusively utilized by the Tenant, as well as the glazing of the windows and the entry doors belonging to the leased premises. If these simultaneously concern façade components, repairs and the like are incumbent upon the Landlord, but at the Tenant’s expense.

The award of relevant orders to specialized businesses as well as the completion of the work shall be coordinated with the Landlord. Because of the complexity of the entire technical facilities and the associated question of guarantees and liability the Tenant may, in principle, hire only those companies, in particular in the heating, air conditioning, ventilation, electrical and sanitary plumbing trades, that are assigned by the Landlord to assure, maintain, support and repair these facilities. The Tenant shall replace textile floor coverings with floor coverings of equal value as needed during the term of the lease and at its own expense. If the Tenant does not comply with any one of the foregoing obligations within a period of 3 months despite a request by the Landlord, the Landlord is entitled to have the necessary repairs and/or work to be performed at the Tenant’s expense. In case of danger because of a delay, no due date is required.

11.4     If heaters and or boilers are used to produce hot water for the leased premises, the Tenant shall be directly responsible for all maintenance, operating, care and cleaning costs and the costs of replacement.

16

11.5     The Tenant is liable to the Landlord for damage to the leased premises or the building caused by itself, its affiliates or employees, as well as by workmen, suppliers, and customers, as well as other persons associated with it. It is in particular liable for damage resulting from the inappropriate handling of water and heating systems as well as allowing doors to stay open or by failure to comply with any other obligation assumed by the Tenant (lighting, etc.).

11.6     The Tenant shall immediately repair any damage for which it is responsible. If it does not meet this obligation after a written reminder within a deadline period set by the Landlord, then the Landlord can perform the necessary work at the Tenant’s expense. In case of danger because of delay or if the Tenant cannot be located, no written reminder and/or set deadline date is required.

11.7     To the extent that the Landlord is responsible for the repair of damage to and in the building or in the leased areas and/or in the leased premises, such damage must be communicated immediately. The Tenant is responsible for further damage caused by giving delayed notification.

11.8     The Tenant shall have equipment that it installs maintained and repaired at its own expense. It is obligated to perform maintenance tasks if a danger to the continued existence of the building or of parts thereof is to be expected.

12. Structural changes

12.1     Structural alterations may only be made by the Tenant with the Landlord’s prior consent. The Landlord can only refuse to agree for significant reasons. A significant reason is present if the structural changes lead to a depreciation of the leased property or if they interfere with the technical facilities of the entire property. The Tenant alone is responsible for obtaining all necessary official permits as well as for compliance with all laws and regulations enacted for these purposes. The Landlord shall, however, be as helpful as possible in the acquisition of any official permits. All costs of any structural changes (including any official fees) shall be debited to the Tenant.

12.2     The Landlord cannot demand restoration of the former condition by the Tenant upon termination of the tenancy if the Landlord has previously agreed to the structural change.

12.3     The Tenant is responsible for any damage which arises in connection with the structural changes it has undertaken.

12.4     The Landlord may perform repairs and undertake structural changes, which become necessary for the preservation of the building or the leased premises, or for the prevention of impending dangers, or for the repair of damage without the Tenant’s agreement. This also applies to work which may not be necessary, but which is advisable, e.g. for the modernization of the building and the leased premises. The Tenant shall make the affected spaces accessible; it may not obstruct or delay the work. If this does not involve the prevention of impending hazards, the Landlord shall take the Tenant’s business interests and operating schedule into account.

17

13. Access of the Landlord to the leased premises

13.1     The Landlord and/or its representative can enter the leased premises during working hours after prior announcement for purposes of examining their condition or for other significant reasons. They are permitted access at any time of day or night in case of danger.

13.2     If the Landlord wishes to sell or sublet the property, it and/or its representative, as well as the prospective customers, may enter the leased premises during working hours after prior announcement. This applies accordingly, as soon as the tenancy has been terminated by one of the contracting parties.

13.3     3 months before the end of the lease, the Landlord is permitted to install 2 50 x 80 cm for-rent signs to the insides of the windows belonging to the leased property.

14. Several persons as Tenant

14.1     Several natural or legal entities are responsible as the Tenant for all obligations arising from the present Contract as jointly and severally liable parties.

14.2     It is sufficient for the legal effectiveness of a declaration by the Landlord, if it is delivered to one of the joint tenants. Multiple tenants are considered to be mutually authorized to receive declarations from the Landlord.

14.3     Facts, which cause an extension or a curtailment of the tenancy for one of the tenants or justify a payment of damages or other claims for or against it, shall have an equal effect upon the joint tenants.

15. General policy provisions

15.1     The Tenant must use the leased premises exclusively for the purposes specified in the Contract and must clean them thoroughly and ventilate them.
