The Lessee may not modify this intended use without the prior written consent of the Lessor, who shall always be entitled to reject the modification providing there are just grounds for doing so.

Article 8: Payment methods – Late payment

Rents, taxes, charges and all other sums owed by the Lessee under the terms of this lease shall be payable as of their due date, which shall constitute a formal notice to pay. They are assignable and shall be paid into the account designated by the Lessor.

Without prejudice to any other rights of, and actions filed by the Lessor, failure by the Lesser to pay any rents, taxes, charges and all other sums owed by it under this lease shall give rise, as of their due date, to the application, as of right and without prior formal notice, of a 7% rate of annual interest.

Article 9: Use of the premises

The Lessee agrees to make use of the premises with due diligence and, in particular, agrees to use the leased premises and other parts of the building in conformity with the provisions of article 10 below.

The maximum authorized ceiling loads, including the partition weight, may not exceed 350 kg/m2 on the upper stories, unless otherwise stipulated in the technical documentation.

The fitting, installation and use of telephones, radios and televisions, as well as teleprinters and other technical equipment inside the leased premises shall be done at the sole risk and expense of the Lessee and under its full and sole responsibility.

If the fitting of the aforementioned equipment is likely to require work outside the building, or in the communal areas, the Lessee shall submit a written request to the Lessor prior to the work. The Lessee shall ensure that its use of said equipment does not disrupt the enjoyment of the other occupants. This work shall be performed at the sole expense of the Lessee.

In accordance with the safety regulations, the fire doors shall never be kept open.

If the Lessee does not comply with its obligations with regard to the maintenance and state of repair of the leased premises, the Lessor shall be entitled, without prejudice to its other rights, to enter the premises and perform, at the Lessee’s expense, any work that the latter has failed to perform.

Article 10: Specifications for Axisparc Technology

The Lessee agrees to comply with the requirements of the specifications for Axisparc Technology, which it acknowledges it has received and agrees to.

These requirements may be added to, modified or amended by Axisparc Technology’s co-owners, in particular to preserve the luxury status of the buildings, to improve the conditions under which the buildings operate or to seek a better distribution of the clauses between the co-ownership by-laws and the other documents that would have to be produced if a new co-ownership were created (basic deed, co-ownership by-laws).

Article 11: Inventory of the premises at the start of the lease

An inventory of the premises at the start of the lease, which shall be final and binding on the parties, shall be drawn up prior to entry into force of the lease and, at the latest, by the time of effective occupation of the leased premises by the Lessee or finally, in the case of the laboratory to be fitted out by the Lessee on the leased premises pursuant to article 4, prior to the premises being fitted out for the Lessee.

This inventory shall be conducted either by an expert designated by the parties by mutual agreement or jointly by two experts, with each party designating and remunerating its own expert. The fees owed to the expert(s) shall be borne equally by both parties.

Article 12: Restitution of the premises

An inventory of the premises at the end of the lease shall be performed in accordance with the same procedure as that described in the previous article, so that the expert or experts can valuate the rental damage and, where applicable, the compensation to be paid to compensate for the unavailability of the premises. The decision of the expert(s), as at the time of the initial inventory, shall be final and binding on both parties.

Upon expiry of the lease, the Lessee shall leave the leased premises in the state of repair in which it accepted them, as stipulated in the inventory made at the start of the lease, allowing for normal wear-and-tear, but without any prejudice whatsoever to the provisions of article 13 below.

However, if the lease is terminated through the fault of, or due to circumstances attributable to the tenant, in a way other than described in the provisions article 4 of this lease contract, the tenant shall be deemed liable for all damage, including normal wear-and-tear, caused during the term of the lease.

It is expressly stipulated that any damage caused by fitting, modifying and removing partitions shall not constitute normal wear-and-tear and shall be attributable to the Lessee, notwithstanding disrepair and normal wear-and-tear.

The requisite restoration work shall be completed by the Lessee before expiry of the lease. Failing this, the Lessee shall be liable to pay, without prejudice to its other obligations, an unavailability compensation equivalent to the amount of the monthly rent at the end of the lease, plus charges and taxes, for the period of months of unavailability estimated by the expert(s), which shall be at least 1 month.

Insofar as is necessary, it is stipulated that if, for whatever reason, this lease were to be renewed and/or were to remain in force beyond the term mentioned in article 3 and no new inventory were drawn up on that occasion, the inventory drawn up at the start of this lease, as well as any addenda thereto, shall serve as a basis for determining the rental damage at the end of the lease.

Article 13: Fitting out, transformations and modifications

Any construction work, fitting out, embellishments, transformations, placing of advertising boards and/or satellite dishes, or new organization of the space on the premises shall be subject to the prior, express and written consent of the Lessor, which may not withhold its consent without reasonable cause.

The Lessor hereby declares that it agrees to the Lessee fitting out the laboratory on the leased premises.

In its request, the Lessee shall provide the Lessor with the work plans that it intends to implement or have implemented for it by a third party on the leased premises, as well as the scope of work, the specifications and the list of materials it intends to use. The Lessee agrees to use only materials that meet the applicable safety standards.

The Lessor shall notify the tenant of its position within 15 calendar days.

If, during and/or subsequent to implementation of the plans, one of the materials used were no longer to meet national or European safety standards and/or were to be downgraded, the Lessee shall be obliged to ensure its replacement as quickly as possible after the downgrading or the risk thereof has been brought to its attention. The removal work shall be performed by a company specifically authorized to do such work.

The Lessee shall ensure that the removal work does not affect parts of the building not leased under this agreement. Should the Lessee fail to repair any damage caused by the removal of hazardous materials within 15 working days of receiving a letter of formal notice from the Lessor, the Lessor shall be entitled to repair any damage or replace the damaged parts at the expense of the Lessee, who shall be bound to refund the Lessor upon presentation of the settled invoice for the work.

The work may only be performed at the expense of the Lessee, who shall bear sole liability in this respect.

The Lessor reserves the right to supervise, at its own expense, any work it has authorized and can require the Lessee to demonstrate proof of a suitable insurance policy.

Moreover, with regard to all work for which a permit is granted, the Lessee shall ensure compliance with all applicable regulations, particularly in terms of the building, operating or environment permits, as well as with any safety regulations applicable to the building, including the safety standards required by the insurer, the Lessor and the fire service.

In the event that significant modifications were to be made to the leased premises by the Lessee during the term of the lease and assuming the Lessor agrees for the leased premises to be delivered in their modified state following the modification work, the Lessor shall be entitled to draw up, at the sole expense of the Lessee, a rider to the inventory established at the start of the lease.

Upon expiry of the lease, the Lessor shall be entitled, without compensation, to preserve any changes, embellishments and modifications made to the premises, unless the Lessee wishes to take them when it leaves, or requires them to be removed and the premises restored partially or fully to their original state at the expense of the Lessee, even if the work was performed with the express consent of the Lessor, providing the latter requests that the Lessee remove these fittings in time to enable the premises to be restored to a pristine state prior to expiry of the contract. The same shall apply to all lighting, bell ringing systems, IT cabling, partitions, sound-proofing, etc. that the Lessee may have fitted.

Article 14: Work, repairs and maintenance

Only the cost of major repairs, as stipulated in the Civil Code, shall be borne by the Lessor, providing they are not attributable to the Lessee. The cost of all other repairs shall be borne by the Lessee.

The Lessee shall maintain the leased premises, at its own expense, in a good state of repair. It shall ensure that the premises and the inside of the windows are cleaned, and that they always remain clean.

If damage requiring repair by the tenant occurs, the Lessor may, subject to written notice sent by registered mail, require the Lessee to perform all the necessary repair work and complete it within two months of sending said written notice. Failure to do so shall entitle the Lessor to immediately have all the work performed at the risk and expense of the defaulting Lessee.

In such cases, the Lessee shall grant access to the leased premises to the Lessor, its representatives and the tradesmen designated by the Lessor, subject to his being forewarned of this, in order to check the state of repair of the leased premises and the building in general and to conduct the necessary inspections and repairs, even if these repairs affect a neighboring tenant, it being understood that this work shall be performed with due care and diligence.

The Lessee shall notify the Lessor, without delay and by registered mail, of any repairs required and for which the latter is liable. Should it fail to do this, the Lessee shall be held liable for any resulting damage and adverse consequences, for which the Lessor may not, under any circumstances, be held liable in the absence of said notification.

The Lessor shall take all steps necessary at the latest within two months of receipt of the registered letter mentioned in the previous paragraph.

In the event that the cost of the repairs is borne by the building’s insurers, the Lessee shall bear the cost of the excess charge, providing it is liable for the loss or the loss is attributable to it, and shall pay the difference between the amount paid out by the insurer and the actual price paid.

The Lessee shall, immediately and at its own expense, replace any broken, cracked or damaged windowpanes.

Article 15: Change of provisions

The Axisparc complex complies with the legal and regulatory provisions, particularly those pertaining to the environment, which were applicable at the time the building permit was granted.

The Lessee shall, under no circumstances, be liable for the clean-up or repair costs or for damage it and/or third parties incurred as a result of a complaint by a third party or an authority or pursuant to a breach of the applicable environmental legislation or regulations, with regard to the presence of pollutants or hazardous (e.g., asbestos) or prohibited substances on the leased premises, in the ground, the basements or in the groundwater, providing this damage or these costs are not the result of the activity performed by the Lessee on the leased premises subsequent to entry into force of this lease agreement.

The cost of any work required under administrative regulations and arising from the Lessee’s activity shall be borne by the latter, without there being any possibility for the Lessee to receive reimbursement from the Lessor when it leaves or to argue for termination of the lease on any grounds whatsoever. This work is subject to the provisions of article 13 of this lease agreement.

Article 16: Guarantee

In order to guarantee the performance of all its obligations under the lease agreement, the Lessee shall obtain, at the time of signing the lease and to the benefit of the Lessor, an irrevocable bank guarantee issued by a bank approved by the Lessor for an amount equal to half a year’s rent, i.e., 177.655 €. The Lessor shall have the right of approval of the guarantor and of the terms and conditions of the guarantee. In the event that the Lessee leases buildings built at later stages, this guarantee shall be adjusted accordingly. This guarantee shall be payable upon first request and payment shall only be requested in the event of gross negligence on the part of the Lessee.

The bank guarantee shall constitute an essential condition of this lease agreement, in the absence of which the Lessor would not have entered into the contract. Any breach of such an obligation shall be deemed serious, which the Lessee expressly accepts.

In the event of adjustments to the rent, the amount of the guarantee shall be adjusted accordingly so that it always equals a sum equivalent to 6 months’ rent.

The bank guarantee shall be issued prior to occupying the leased premises.

In any case, said terms and conditions of the guarantee shall stipulate that the guarantee is lodged for a period that shall expire at the earliest three months after expiry of the lease.

This guarantee shall be returned to the Lessee three months after the end of the lease, providing the latter can demonstrate that it has fully performed all its obligations under the lease. During the term of the lease, the guarantee may not, under any circumstances, be offered or allocated, in full or in part, by the Lessee in order to pay the rent or other contractual debts.

Should the Lessee be declared bankrupt, the guarantee may be used by the Lessor to compensate for payment arrears or other breaches by the Lessee of its obligations, including rents and communal charges.

Without prejudice to this guarantee, and in accordance with article 1752 of the Civil Code, the Lessee shall still be bound to keep the leased premises fitted with furnishings, the value of which is sufficient to cover at least 6 months’ rent.

The Lessor reserves the right, at any time, including after early termination of the lease, to request securities that are sufficient to cover the rent if the Lessee does not furnish the premises sufficiently.

Article 17: Assignment and subletting

The Lessee may only assign this lease agreement or sublet the premises, either in full or in part, after notifying the Lessor in writing, it being understood that the latter may refuse to authorize the assignment of the lease or the proposed subletting, providing there are justifiable reasons for doing so.

In the event that the Lessor approves the assignment or subletting, the Lessee, the sub-lessee, the assigner and the assignee shall be jointly and severally liable with regard to the Lessor for all obligations arising from this lease and the co-ownership regulations. The Lessee agrees to ensure that the sub-lessee or the assignee expressly commits to such obligations with regard to the Lessor. Failing this, the assignment or subletting cannot take place, even if the Lessor had given its prior written consent, except if, in that consent, it had expressly waived the need for such a commitment.

The term of the sublet shall, under no circumstances, exceed the term of this lease agreement.

Upon conclusion of the assignment or sublet agreement, providing it has been authorized, the Lessee shall provide the Lessor with a registered copy of the agreement.

Article 18: Hold harmless provision—Insurance

A. Hold harmless provision

1. The Lessee hereby holds the Lessor harmless from any inconvenience and tangible and intangible damage that it might incur as a result of adverse events, such as fire, water damage or accidents. This includes, in particular, accidental damage and disruptions to water, gas, electricity, heating and bell ringing systems or any other technical systems within the building.

This provision shall apply to the Lessor, the companies within its group and their staff.

2. The Lessee agrees to ensure that the sub-lessees, occupants and their representatives make the same written declaration with regard to the Lessor.

3. In return, the Lessor shall, for the duration of the lease, hold the Lessee, the sub-lessees, occupants and their representatives, harmless from any damage covered by the fire insurance policy stipulated in point B 1 below.

4. The aforementioned hold harmless provisions shall, however, be null and void when the person benefiting from them under normal circumstances intentionally caused the damage.

B. Insurance

1. The Lessor shall take out, through the building’s co-ownership structure, and maintain, throughout the term of the lease, an insurance policy covering the leased premises. This insurance policy shall contain a hold harmless clause, as mentioned in point A.3. of this article; it shall, at all times, provide the broadest possible coverage, as deemed judicious by the Lessor and, in any case, shall cover damage caused as a result of strikes and riots: it shall also cover the Lessee, as the insured, for damage other than bodily harm caused to third parties by fire, explosion and water when the insurance loss accident originates on the leased premises.

2. The Lessee shall take out, within one month of receiving the keys, as stipulated in article 26 of this lease agreement, and maintain, throughout the term of the lease, an insurance policy covering the contents of the leased premises. This policy shall contain a holds harmless clause, as mentioned in point A.l. of this article.

3. The Lessor and the Lessee may, at any time, request proof of the existence of the insurance policies mentioned in 1 and 2 above and of the coverage they provide.

4. The Lessee shall contribute to the cost of the insurance in accordance with the terms set out in article 7B of this lease. If an insurance loss is attributable to the Lessee, it shall be invoiced for the excess in the following quarterly bill for charges.

5. Should the activities of the Lessee or of those accountable to the latter lead to increased insurance premiums for the Lessor and other tenants in the building, the cost of this increase shall be borne solely by the Lessee.

Article 19: Waiver of liability for the Lessor and its beneficiaries

The Lessee shall guard and effectively protect the premises it is leasing. It expressly and fully waives the liability of the Lessor and its beneficiaries in the event of theft at the leased premises.

In the event that administrative or judicial proceedings were filed against the Lessor due to the activity or presence of the Lessee on the leased premises, the Lessee agrees to hold the Lessor harmless and to bear the consequences of any resulting prosecution.

Article 20: Insolvency – Merger – Division

In the event that the Lessee is declared bankrupt or in receivership, the Lessor shall be entitled to terminate the lease without notice. The Lessee shall be obliged to notify the Lessor of any bankruptcy or receivership proceedings. The Lessor shall provide notice of its decision by registered mail within three months of receiving notification of the event justifying termination.

In such cases, the Lessee shall be liable to pay a basic, irreducible compensation equal to 6 months’ rent (which cannot be cumulated with the compensation foreseen in article 21), plus charges and its share of taxes, in addition to the rent, charges and taxes for the current quarter, and this without prejudice to the application of all articles in this lease, in particular articles 12, 13 and 14.

The Lessee shall notify the Lessor of any merger, absorption or break-up, without this being deemed grounds for the Lessor to terminate this contract.

Article 21: Judicial rescission

In the event of the judicial rescission of this lease due to the fault of the Lessee, the latter shall be liable to pay a basic, irreducible compensation equal to 6 months’ rent, plus charges and its share of taxes, in addition to the rent, charges and taxes for the current quarter and in addition to all other expenses that the Lessor is entitled to claim from the Lessee, and this without prejudice to the application of article 12 above.

This provision may, under no circumstances, be invoked by the Lessee in order to relieve itself of its obligations under this lease agreement.

The Lessee acknowledges that it has been apprised of and accepts the fact that any breach of the obligations under articles 3, 5, 7, 8, 13, 16, 17 and 18 shall be deemed sufficiently serious to justify the Lessor instigating proceedings to obtain rescission of this lease through the fault of the Lessee.

Article 22: Expropriation

In the event of expropriation for reasons of public interest, the lease shall expire on the date at which the expropriating public, private or general interest authority is to take ownership of the premises.

Under no circumstances may the compensation that the Lessee is entitled to demand from the expropriating authority lead to the reduction of the amount of the compensation payable to the Lessor by the expropriating authority. The Lessee shall not be entitled to any compensation from the Lessor and shall assert its rights with regard to the expropriating authority under separate proceedings.

The Lessor shall notify the Lessee, at the earliest opportunity, of any expropriation procedure and update it on the status of said procedure. In the event of expropriation, the Lessee shall not be bound to restore the leased premises to a state in which they could be leased out again, as stipulated in article 12.

Article 23: Access to the premises

The Lessee shall, at all times, allow access to the leased premises for the Lessor and its representatives, subject to at least two working days’ notice, in order to enable them to conduct inspections and, where applicable, perform any necessary repairs and maintenance.
