PRELIMINARY DECLARATION

This
lease has been entered into and accepted according to the charges, clauses and terms and conditions stipulated herein below, as well as in compliance with the legal provisions in force, in particular the status of commercial leases, resulting from
the provisions of Articles L 145-1 et seq. and R 145-1 et seq. of the Commercial Code, as well as the provisions of the noncodified decree of 30 September 1953, with which the Lessee undertakes to comply.

The foregoing shall be applicable both to the Lessee and to any assignee or occupant to whom the Lessees rights shall regularly pass, during the term of
this lease as well as during its renewals, if any.

This clause aims to specify the legal, regulatory or contract provisions to which the Parties agree to
refer, to the exclusion of any contractual extension of the enjoyment of the status of commercial leases in favour of the Lessee, which must prove that it fulfils the legal or regulatory conditions applicable in particular during renewals.

Under this agreement, the notion of lease covers this lease, it renewals, if any, and/or its extensions, if any, such that, unless as otherwise stipulated,
all obligations applicable herein shall apply throughout the term of the lease, its renewals, if any, and/or its extensions, if any.

into two parts that constitute an indivisible whole:

|--------- |  | ----------------------------
|Part One: |  | GENERAL TERMS AND CONDITIONS
|          | 
|Part two: |  | SPECIAL TERMS AND CONDITIONS

it is hereby stated:



| |  | that in the event of contradiction following this lease between the two Parties, the special terms and conditions shall supersede the general terms and conditions,
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | that any tolerance, respecting the terms and conditions of this lease and its consequences, whatever the frequency and duration, may never be deemed as an amendment or an elimination of said terms and conditions.
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These clauses are crucial for the common intention of the Parties.

effective date of the lease, as specified under the Special Terms and Conditions of this lease, and the end of the ongoing quarter, the Lessee, upon receiving an invoice, shall pay the main rent calculated prorata temporis based on the time

4.2 BANK TRANSFER

The Lessee shall pay all amounts payable as rents, including the principal rent and associated costs, under this lease by cheque or bank transfer from the
Lessees bank account no later than the first day of the civil quarter into the Lessors bank account.

In this regard, the Lessor shall give
the Lessee a copy of the details of the bank account into which the transfer should be made.

The Lessee shall ensure that enough funds are available on
its account to make the transfer possible. The Lessor shall specify the transfer amount to the Lessee at least a fortnight before the each due date.

In
the event of a change in Lessors banking information, the Lessor shall give the Lessee new bank details.

Where, whatever the reason, the payment of
the amounts payable at the contractual due date as back rents, charges and associated costs could not be made by bank transfer, the Lessee shall in any case pay by any other method, excluding in cash, the amounts due accordingly, on the first day of
each quarter to meet contractual maturities set forth above

4.3 RENT INDEXATION

The rent stipulated hereinabove is linked to changes in the index set forth under the Special Terms and Conditions.

It is specified that this clause is a contractual indexation and does not refer to the three-yearly review provided for under Articles L 145-37 and L 145-38
of the Commercial Code. The Parties are thus justified in expecting the rent to be reviewed in accordance with the public order provisions of said Articles L145-37 and L145-38 of the Commercial Code.

As a result, the rent shall automatically and without any prior formality be increased or reduced each year on the anniversary date of the effective date of
the lease to reflect changes in the said index.

For the first rent indexation, the base index shall be the one referred to under the special terms and
conditions, and the review index shall be that of the same calendar quarter of the following year.

For subsequent indexations, the base index shall be
the previous review index and the review index shall be that of the same calendar quarter of the following year.

It should be noted that the annual rent
indexation is an essential and crucial condition of this agreement: where the benchmark index ceases to exist and where the lawmaker fails to automatically replace it with another index, the Parties shall agree to a substitute index and if they do
not, the index shall be determined by the President of the Tribunal de Grande Instance (district court) in whose jurisdiction the premises are situated, ruling in emergency proceedings, to whom the matter was referred at the request of the first
party to act, with the costs associated with the proceedings shared 50-50 by each of the Parties.

4.4 RENT FOR THE RENEWED LEASE

4.4.1. Principle



- Page 6 of 37 -



---

As an essential and crucial condition of this lease, it is hereby stipulated that in the event of renewal under
the terms and conditions of this lease, the renewal rent shall be set at:



| |  | the market rental value, as defined below,
|- |  | ------------------------------------------

The price of the renewed lease thus set shall be applicable from
the first day when the renewed lease takes effect, even if the price is higher by more than ten per cent (10%) than the last rent paid, by way of derogation from the last paragraph of Article L.145-34 of the Commercial Code.

Unless as otherwise expressly stated, any other clauses and terms and conditions of the Lease shall be maintained and applied under the renewed lease.

4.4.2. Market rental value

The rental
value shall in any case be calculated exclusively by comparison with market rents, i.e.,:



| |  | prices freely discussed by the landlord and their tenant for vacant premises, to the exclusion of references to amicable renewals and fixing of rents by the court for signed leases with effective date running during the
twelve (12) months prior to the renewal,
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | for real property comparable to the premises, i.e., buildings of a similar nature to the building, situated within the same perimeter and having particulars similar to those of the premises (prestige, standard with
regard to quality, construction, integrated services, technical equipment, functionality), unless where they are to be corrected if such characteristics fail to meet other reference criteria, subject to such criteria being comparable.
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Amounts for the assignment of rights under the lease as well as lease-premium, the amount for work done by the tenants, and the effect, if
any, of the progressive nature of rents on the term of leases.

This article is decisive factor in the Parties willingness, without which the lease
would not have been signed, and shall be applicable to any assessor called upon to give an opinion on the rent amount.

4.4.3.
Determination of market rental value

The market rental value shall be established, in all cases where it is applicable under the lease, according to
the following process, from which the Parties may not depart in any case whatsoever.



| |  | The market rental value, in the absence of agreement between the Parties, shall irrevocably be set by a property valuer chosen from the list of property valuers maintained at the Paris Court of Appeal, it being
understood that the valuer must not have worked for one of the Parties within the twelve (12) months prior to their appointment. The valuers fees and costs shall be borne 50-50 by each of the Parties.
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | In the event that the Parties fail to agree on the name of a valuer or where all valuers worked for one of the Parties within the twelve (12) months prior to their appointment, the party that acts first shall refer
the matter to the President of the Paris Tribunal de Grande Instance, ruling in emergency proceedings, who shall appoint a valuer.
|- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- Page 7 of 37 -



---

The valuer shall act within the framework of a common interest mandate, just like the third party charged with
calculating the legal price of the sale (article 1592 of the Civil Code).

The valuer shall give its decision within two (2) months of the matter
being referred to them. Their decision must irrevocably bind the Parties and may not be appealed.

However, this procedure shall have no impact on the
Lessors option to refuse to renew the lease or on that of the Lessee to terminate their lease as provided for below.

4.4.4.
Right of option

It is expressly agreed between the Parties that they shall, no later than within one (1) month of service (by the party that acts
first) of the valuers decision, draw up a new lease under the conditions set forth in said decision, unless the Lessee chooses not to renew the lease or the Lessor refuses to renew it.

a) Where, within a period of one month, the Lessee waives the opportunity to renew the lease, the Lessee must notify the Lessor of such decision by means of
an extrajudicial document. In that case, the Lessee may only vacate the premises upon the expiry of a six-month period following the date of notification by the Lessee of its decision to take advantage of this
clause, by way of express derogation to the common practice under Article L.145-57 (2) of the Commercial Code.

The Lessee shall continue to be bound
during this period by all obligations under the lease, with rents, as a result, being set as provided for under Article 4.4.

a) Where, within a period of
one month, the Lessor refuses to renew the lease, the Lessor must notify the Lessee of such decision by means of an extrajudicial document.

4.5
CONTRACTUAL INTERESTS AND COLLECTION COSTS

If any amounts payable, including charges and taxes, are not paid when they fall due, the Lessee
shall automatically be required to pay an interest set by contract at the legal interest rate, plus two points, per month from this date.

Moreover, any
correspondence sent to the Lessee calling on it to pay a rent or any other amounts remaining outstanding ten days after the due date shall give rise to the collection of a lump sum of fifty euros in administration fees.

Any costs, fees, or emoluments payable to lawyers, bailiffs and auctioneers, in return for any service rendered to collect sums outstanding after the agreed
due date, shall be borne by the Lessee as penalties under article 1152 of the Civil Code.

4.6 PENALTY CLAUSE

Also, upon the expiry of a period of eight days following each due date, any amounts payable, plus the late penalties referred to above, shall be automatically
increased on a flat-rate basis by 10%, without the need for any formal notice, irrespective of the costs of possible deeds or writs, costs of



- Page 8 of 37 -



---

proceedings, as well as any interests payable under the law, any damages such as the bringing into play of the defeasance clause, if any.

4.7 ALLOCATION OF PAYMENTS

By way of derogation
from Articles 1253 to 1256 of the Civil Code, the allocation of payments of outstanding amounts by the Lessee when they fall due or their contractual maturity date shall be as follows:

1    -    Cost of collection and proceedings

2    -    Contractual late payment penalty under Article 4.5 of this lease

3    -    Amount of the penalty clause under Article 4.6 of this lease

4    -    Any addition to or adjustment of the security deposit amount

5    -    Rent, charges or occupation compensation

ARTICLE 5  SECURITY DEPOSIT

5.1To
guarantee the performance of its obligations under this lease, the Lessee shall pay to the Lessor, upon the signature hereof, an amount representing three (3) months of rent, excluding taxes and charges, as a security deposit.

The non-interest-bearing amount shall be returned to the Lessee at the end of the lease after moving and handing back keys, subject to justification of
payment of all taxes and charges, carrying out of repairs for which it is responsible and upon deduction of any amounts payable to the Lessor or for which the Lessor may be held responsible due to an action of the Lessee in any capacity.

Each time the rent is adjusted, both in the event of a review and renewal, the security deposit shall, automatically and without any formality, be reduced or
increased in the same proportions such that it at all times shall be equal to three months of the principal rent, excluding taxes and charges.

Since
compensation is expressly provided for, the Lessor shall have the right to deduct from said security deposit without any formality, the amounts of rents fallen due but not paid, as well as any other amounts payable for any other reason, in which
case the Lessee shall be bound to make up for or replenish the security deposit on first demand in order to maintain the security deposit at all times at the agreed number of rent periods.

Where the lease is terminated in accordance with Article 1184 of the Civil Code or by application of the defeasance clause due to failure to fulfil terms and
conditions or for any other reasons attributable to the Lessee, the security deposit shall remain forfeited to the Lessor as up-front damages without prejudice to any other compensation.

5.2In case of collective procedure by the Lessee and in accordance with Article L.622-7 of the Commercial Code, the Lessor, if it so wishes, may
offset the amount of the security deposit against any amounts payable as rents, back rents, occupation compensation, charges, interests or



- Page 9 of 37 -



---

penalties, on account of they are all related. The Parties have immediately decided that the security deposit shall as a priority be set off against rents prior to the court ruling initiating the
collective procedure.

The Lessee or the assignee shall fully replenish the security deposit by giving the Lessor the corresponding amount.

Furthermore, if the administrator or liquidator were to terminate the lease by waiving the option granted under Article L. 622.13 of the Commercial Code, the
failure to fulfil terms and conditions shall result in damages payable to the Lessor, which damages the Parties have agreed to set at a flat-rate basis and finally at three months of rents including taxes.

ARTICLE 6 - CHARGES, TAXES AND FEES, VARIOUS BENEFITS AND CLAIMS BORNE BY THE LESSEE

|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The fees of the Landlords architect shall be borne entirely by the Tenant,



| |  | compliance with the legislation relating to employment law, health and safety and Establishments Open to the Public, to roadways, cleanliness, the police, the Employment Inspectorate and the protection of the
environment
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Tenant will be obliged to undertake its works, to continue them with diligence and to complete them within the agreed
deadlines and to complete them in compliance with the environmental annex if such exists.

The Landlords authorisation will in no event incur its
liability, nor attenuate that of the Tenant, both between the Parties and with regard to third parties.

The Tenant undertakes to bear all the
consequences of its works, which may be prejudicial to the primary construction and to the solidity of the building, and to compensate the Landlord and any third party for any losses, of any kind whatsoever, which may be caused by the execution of
the said works.

8.2 OTHER WORKS

The
improvement and internal decorative works on the premises will be carried out by the Tenant at its expense, after obtaining the agreement of the Landlord or its representative or from the co-ownership syndicate and the governmental authorisations
which may be required, and in accordance with the conditions indicated in the descriptive estimate which it will be obliged to have prepared and to provide to the Landlord.

Indeed, prior to the execution of the works, the Tenant will be obliged to submit its file of improvements to the Landlord or to its representative in order
(i) that it can verify its compliance with the Co-ownership Regulations and/or the Regulations of the Free Syndicate Association, if the



- Page 17 of 37 -



---

building is subject to such resumes, as well as to the Internal Regulations of the building, (ii) and that it can give or not give its authorisation.

The Tenant will be obliged to undertake its works, to continue them with diligence and to complete them within the agreed deadlines and to complete them in
compliance with the environmental annex if such exists.

Any authorisation from the Landlord for the completion of the works covered in the present
article does not imply any commitment of responsibility on its part; consequently, the Tenant undertakes not to take proceedings against the Landlord, and this even if the works or the contractors have been approved by the latter.

It is hereby specified that the authorisation given, where applicable, by the Landlord will be an authorisation in principle and that in no event will the
Landlord guarantee the feasibility of the planned works or the various consequences which may result therefrom.

All controls, verifications and works to
which the leased premises, the improvements, installations and equipment which they contain may be subject, as a result of applicable or future regulations, will be entirely at the expense of the Tenant, which renounces any right of recourse against
the Landlord, including four deteriorations and hindrances to enjoyment which are likely to result therefrom.

The Tenant will therefore alone assume the
complete responsibility which may result from the execution of these works and will be obliged to cover or have covered all the risks by insurance policies subscribed in accordance with the provisions set out in the present lease.

In the event of completion of works without the agreement of the Landlord, the latter will be entitled to require that the leased premises are restored, at
the expense of the Tenant, to their original state, without prejudice to the application of the sanctions incurred under the terms of the present lease or the legislation in effect.

8.3 END USE OF THE TENANTS IMPROVEMENT WORKS

8.3.1.All works, decorations, improvements, installations, building works and highest increases whatsoever (including fixed, mobile or movable
partitions) and, where applicable, the works imposed by the applicable regulations, carried out by the Tenant, either on its entry into the premises or during the course of the lease, will become, by means of accession, at the end of each of the
successive leases or prior to that date if the lease is terminated early, the property of the Landlord, without compensation.

The Landlord may
nevertheless require, on the departure of the Tenant, the restoration of the premises, in whole or in part, into their original state, at the expense of the Tenant, even for works authorised by the Landlord and even for those which may have been the
subject of accession to the latter at the time of a previous lease renewal.

The original state of the premises means that mentioned in the property
inspection report prepared at the time of entry into enjoyment of the Tenant, and as shown, where applicable, on the plan appended thereto. In the event of the assignment or free-of-charge transfer of the leasing rights, this property inspection
report corresponds to that prepared with the initial tenant which concluded the lease and not to that prepared between the Landlord and the assignee or the beneficiary of the leasing right at the time of its entry into the premises.



- Page 18 of 37 -



---

The restoration works necessary to remedy any damage resulting from the removals will be the responsibility of
the Tenant.

8.3.2.In any event, the Tenant will bear the costs related to the improvements, additions, building works and height increases made
by it, until the end of the enjoyment of the premises and this even when these have been transferred to the Landlord.

The Tenant will thus be obliged to
bear the costs resulting from defects, malfunctions and conformity defects related to the legal standards which may affect the improvements, additions, building works and height increases carried out by it.

The Tenant will also be obliged to bear the costs of maintenance and, where applicable, bringing into compliance of the improvements, additions, building
works and height increases carried out by it, until the end of the enjoyment of the premises. It will check that these are, at the time of their completion and at any time subsequently, in compliance with the requirements of the heating regulations.

The Tenant undertakes to guarantee the Landlord against any claim by a third party or neighbour in respect of the improvements, additions, building works
or height increases carried out by it.

8.4 EXTERNAL INSTALLATIONS

The Tenant will not be entitled to carry out any installation of awnings, verandas, windbreaks, external blinds or any surface-mounted objects on the facade of
the building without having previously obtained the express written consent of the Landlord, as well as the governmental authorisations required for this purpose and, where applicable, the agreement of the Co-ownership Syndicate of the building
and/or the Free Syndicate Association.

In the event that the required authorisations should be granted to it, it will be obliged to maintain the
installations or improvements made in a very good state of maintenance and to monitor their solidity in order to avoid any accident; it commits, at the time of its departure, to removing the said installations and returning the premises in their
original state, unless agreed otherwise between the Parties.

In addition, the Tenant will be obliged to pay all the taxes and charges arising from these
installations.

8.5 SIGNS

The Tenant will
only be entitled to install an external sign (illuminated or not) with the written agreement of the Landlord or its representative, and if necessary of the Management Syndicate, the General Meeting of the Co-owners or the Free Syndicate Association,
to which must be sent in advance the price quotations and plans allowing for determination of the exact details of the installation of the planned change.

In the event of a refusal of the authorisation by the management syndicate, the General Meeting of co-owners or the Free Syndicate Association, the Tenant
hereby renounces any rights in this respect against the Landlord on any grounds whatsoever.

The Tenant will be obliged to take personal responsibility
for obtaining any governmental authorisations required, and also for the payment of any charges due for this purpose.



- Page 19 of 37 -



---

It will ensure that the sign is always solidly attached and will remain solely responsible for any accidents
which this installation may occasion.

Any modification to the installation of the existing signage, of any kind whatsoever, will have to be the prior
subject of a request for authorisation from the Landlord in accordance with the terms stipulated previously.

The Tenant undertakes to insure that, at the
time of its departure, the sign is removed and the premises are restored to their original condition.

ARTICLE 9 - UPKEEP AND REPAIR WORKS OF THE
PREMISES RENTED BY THE TENANT - COMPLIANCE WORK - LESSORS WORK  VARIOUS INTERVENTIONS

9.1 UPKEEP  REPAIRS 
COMPLIANCE

For the purposes of paragraphs a) to d) of clause 9.1, the parties agree that, pursuant to Article R 145-35 of the French Commercial
Code in the wording in force on the date of signature of this lease, the following fall on the Lessor:



| |  |  | the expenses for the major repairs listed in Article 606 of the Civil Code and, where appropriate, the fees for the execution of those works,
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the expenses for works to fix the poor state of, or bring into line with regulations, the rented premises or the building in which they are located, once those works have addressed the major repairs mentioned in Article
606 of the French Civil Code.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In accordance with that article, the aforementioned expenses for upgrading work for which the amount exceeds
the cost of an identical replacement shall fall to the Tenant.

a/ The Tenant shall keep the premises and their fittings in very good condition and shall
carry out maintenance and repairs of any kind, including for damage resulting from usage, dilapidation, a hidden defect and force majeure.

The Tenant
must, in particular, at its own expense and under its own responsibility, keep in a very good working condition, safe and compliant with the standards necessary, throughout the duration of the lease, its renovation or refurbishment, the upkeep and
repair of all closing devices, doors, glazing, general locks, floors, pipes, taps and all specific facilities and fittings, such as electronic or telephonic fittings, computer cabling, meters, outlets and drains, and bathroom facilities. This list
is only indicative and not exhaustive. To that end, the Tenant shall, at its expense take out all upkeep and maintenance contracts, with a view to ensuring that the fittings work and are maintained, and undertakes to supply the Lessor with a copy of
those contracts upon the latters request.

The Tenant must also maintain, repair or replace at its own expense and under its own responsibility, any
glazing which covers some parts of the rented premises (but only within the limits set under Article 145-35 of the French Commercial Code) and shall have no legal remedy against the Lessor for damage caused by water leaks from that glazing.

The Tenant shall also refurbish as often as necessary and at least every nine years any painting, wall-coverings and flooring.



- Page 20 of 37 -



---

In general, the Tenant shall, at its own expense and under its own responsibility, repair or replace anything,
when they become necessary and for any reason whatsoever.

The Tenant shall take out at its own expense all maintenance contracts for the appliances or
equipment installed in the rented premises and shall ensure that all security and prevention fittings work and are maintained, so that the Lessor may not be pursued or bothered by anyone on that subject.

b/ The Tenant shall be responsible for any repairs which would normally fall to the Lessor but which are needed because either the Tenant has failed to make
any necessary repairs under its responsibility or the Tenant, its staff or visitors have caused damage in either the rented premises or other parts of the building.

The Tenant must inform the Lessor without delay of any repairs likely to fall to the latter.

The Lessor shall only be responsible for expenses arising from the major repairs mentioned in article 606 of the French Civil Code and, where necessary, the
fees for the execution of those works, except for expenses arising from upgrading work for which the amount exceeds the cost of identical replacement, pursuant to article R145-35 of the French Commercial Code.

c/ Whether during the lease or during possible renovation works, the Tenant must scrupulously comply, at its own expense, with all legal or regulatory
provisions in force or which become applying after this lease is signed, with particular regard to refuse, hygiene, health, safety, police, inspection of the work and environmental protection, including thermal regulations. Furthermore, the Tenant
shall carry out, at its own expense and under its own responsibility but only within the limits set out in Article R 145-35 of the French Commercial Code, works to ensure that the premises and its facilities comply with all legal and regulatory
provisions so that the Lessor is never bothered or pursued by anyone on that subject.

d/ In order to check the condition of the rented premises, the
Lessor reserves the right to visit them subject to a notice period of 2 working days. However, the Lessor may visit the premises without providing any notice in the event of an emergency.

Any checks, inspections and works to which the rented premises or the appliances, fittings and facilities within them may be subject, under applicable or
future regulations, shall fall fully to the Tenant, who waives the right to any remedy against the Lessor, including for damage and disturbances likely to arise caused by them.

9.2 WORK CARRIED OUT BY THE LESSOR IN THE PROPERTY OR NEIGHBOURING PROPERTY OR ON PUBLIC ROADS

The Tenant shall endure, without compensation or rent reduction, irrespective of their length, even if it exceeds twenty-one (21) days, by derogation from
Article 1724 of the French Civil Code, major repairs and any works which must be carried out in the premises or on the property, particularly work to improve environmental performance, on its own initiative, the initiative of the Lessor, neighbours
or third parties, even if they do not benefit the Lessor, and any nuisance caused



- Page 21 of 37 -



---

by those works. The Tenant shall endure works carried out on neighbouring buildings or public roads in the same conditions, and the Lessor may not be held liable for any reason whatsoever.

Furthermore, by derogation from Article 1723 of the French Civil Code, the Tenant must also endure, without compensation or rent reduction and without remedy
against the Lessor, any modification to the premises or communal areas and items in the property, that the latter reserves the right to carry out.

The
Tenant must in any case leave free access to the water and gas pipes, electrical wiring, heating, air-conditioning and ventilation shafts or other channel, and must, at its own expense and without delay, move or dispose of all appliances, furniture,
materials, signs, etc. which must be removed to carry out any works by the Lessor, including in particular when cleaning or carrying out work to improve the buildings environmental performances.

9.3 VISITING THE PREMISES IN THE EVENT OF TERMINATION OF THE LEASE

Once notice for the termination of the lease has been given and for at least the last six months of this lease, or in the event that the rented premises are
put up for sale, the Tenant must allow potential tenants accompanied by an employee of the Lessor to visit the premises, on any working day, subject to a notice period of 2 working days. Furthermore, the Tenant must leave notices, including banners,
affixed to the windows or balconies.

ARTICLE 10 - LIABILITY - WAIVERS

10.1 INTERRUPTION/CANCELLATION OF SERVICES

The
Tenant may not claim any compensation or reduction in rent, or hold liable the Tenant, its representatives and their respective insurers in the event of a temporary interruption, an irregularity or a temporary cancellation to the following services:
water distribution, electricity, telephone, any automatic system and IT system depending on the property, air conditioning, ventilation or any other related to the property.

10.2 LIABILITIES AND CLAIMS

The Tenant expressly
waives the right:



| |  | to request compensation or a rent reduction in the event of damp or a flood caused by water leaks or pipe breakages, for any reason whatsoever, to hold liable the Tenant, its representatives and their respective
insurers, for disturbances or damage caused by neighbours or third parties, in any way, particularly in the event of theft or misappropriation, of which the Tenant, its staff, suppliers customers or visitors may be victim in the rented premises or
in the property, and the Lessor is not obliged to provide any surveillance.
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | to hold the Lessor liable, in the event of physical or non-physical damage, for compensation for loss of use or operating loss, as a result of the total or temporary stop to its activity for any reason whatsoever.
|- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Tenant shall be personally responsible for:



- Page 22 of 37 -



---

| |  | the repair of any physical or non-physical damage, acting directly against the perpetrators without remedy against the Lessor.
|- |  | ------------------------------------------------------------------------------------------------------------------------------



| |  | any complaints from neighbours or third parties, particularly because of noise, smells, heat or generally any damaged caused by its activity, and the Lessor shall not be bothered in any event of that type.
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

10.3 EXPROPRIATION

In the
event of expropriation in the public interest, no claims may be made against the Lessor; it shall fall to the Tenant to assert any rights arising from this agreement and from the activities carried out in the rented premises on the expropriating
party.

10.4 DESTRUCTION OF THE RENTED PREMISES

In the event that, following an accident of any kind, irrespective of its origins, the rented premises are left fully unusable or destroyed, this lease shall
be terminated ipso jure and without compensation.

If the rented premises come to be partially destroyed or unusable, the Lessor, alone and depending the
extent of the damage, may either terminate this lease ipso jure or agree a rent reduction for the length of the partial loss of use. It is specified that, in the latter case, and on the condition that the Lessor rebuilds the property within a
maximum deadline of two years, this lease shall continue to concern all the rented premises and the rent reduction shall be calculated according to the size of the area destroyed. This shall be calculated by the Lessor or its representative. In the
event that the Tenant does not agree with the calculation, the Parties agree that they shall bring the matter before the competent court and, while they wait for its decision, they shall provisionally accept the calculation by the Lessor or its
representative.

In the aforementioned situations, the Lessor shall, nevertheless, retain its possible rights against the Tenant if the destruction can be
partially or fully attributed to the latter.

Accordingly, the Tenant may only, under express agreement, claim compensation awarded by the insurance
company or companies for the damages caused to it, without prejudice to the ensuing consequences with regard to this lease according to the terms stipulated below.

ARTICLE 11 - INSURANCE

11.1 LESSORS
INSURANCE

The Lessor has taken out insurance policies to cover the building and/or rented premises against the risk of fire, explosions,
electrical damage, storms, water damage, riots, attacks, acts of terrorism and sabotage, and loss of earnings. It has also taken out civil liability insurance in its capacity as a property owner.

The Parties agree that the potentially applicable excesses shall be borne by the Tenant.

11.2 TENANTS INSURANCE



- Page 23 of 37 -



---

The Tenant must take out insurance, for the entire duration of the lease, for a sufficient amount, to cover its
fixtures, fittings, equipment, appliances and amenities, and the improvements, extensions, structures and storeys it has added, even if they are immovable by nature, as well as its operating loss, with a reputably solvable company against the risk
of fire, explosions, electrical damage, storms, water damage, riots, attacks, acts of terrorism and sabotage, and claims by neighbours and third parties. The Tenant must also have the rented premises insured against glass breakage.

In the event of an accident, if the Tenant considers the sums that it will have received under its Operating Loss policy, no remedy may be pursued
against the Lessor.

The Tenant undertakes to take out a civil liability insurance policy to cover for damages caused to third parties resulting from its
operations or the improvements, extensions, structures and storeys it has added on the premises. Physical injuries must be covered to a minimum of 3,000,000 per accident and physical and consequential non-physical damage to a minimum of
760,000 per accident. This minimum may be increased at the request of the Lessor.

The Tenant must send the Lessor a copy certified as
conforming with the original of its policies or, failing that, a cover note or statement, in which, where relevant, the improvements, extensions, structures and storeys it has added are mentioned. The document must be issued by its insurer and, the
first time, before it has been implemented.

It should also be able to prove the validity of its insurance and the payment of its premiums at any moment.

If the Tenant fails to take out the aforementioned insurance policies or if the Lessor considers those policies not to cover large enough sums, the
latter may take out insurance for the risks itself, and the Tenant shall undertake to reimburse the Lessor for the relevant premiums upon request.

Furthermore, the Lessor undertakes to inform the Lessor of any change in its operating conditions which the insurance company could consider an increased
risk. If the Tenants activity or the change in operating conditions results in a higher premium, either for the Lessor or for the neighbours or other tenants, the Tenant shall reimburse the interested parties for the amount of the higher
premium.

Likewise, if the improvements, extensions, structures and storeys added by the Tenant results in a higher premium for the Lesson, the Tenant
undertakes to bear the cost.

By express agreement, under this lease, compensation due to the Tenant in the event of an accident, amounting to the
compensation that the Lessor owes to the Owner, may be delegated and transferred to the Lessor.

The Tenant also undertakes to comply with any request
made by the Lessors insurers aimed at modifying the technical fittings for the prevention and security of the rented premises.

Furthermore, in the
event that the Tenant carries out work in the rented premises in the conditions set out in Clause 8, that party must take out the necessary insurance for that purpose and third-party liability cover in particular for the works, as well as a Ten-Year
Guarantee and guarantees for Proper Operation, Consequential Damage and Damage to Existing Property in compliance with the legislation in force.

11.3
RECIPROCAL WAIVER OF RECOURSE



- Page 24 of 37 -



---

The Lessee waives the right to any recourse that it may exercise against the Lessor, its principals or
representatives, or its insurers. It agrees to obtain the same waiver from its insurers, any of its occupants and their insurers, and to indemnify the Lessor for the direct or indirect consequences of any claim or legal action that its occupants,
employees and/or insurers may frame or bring against the Lessor, including all costs and expenses that the Lessor may incur when exercising its rights.

Reciprocally, the Lessor, its principles and representatives waive the right to any recourse against the Lessee and against its insurers. They agree to obtain
the same waiver from their insurers.

11.4 DAMAGE

The Lessee shall inform the Lessor or its representative, within 48 hours, of any repair that becomes necessary during the lease, as well as any damage or
deterioration that occurs at the leased premises, regardless of its significance, even if no apparent damage has occurred, subject to being held personally liable and therefore being required to compensate the Lessor for any direct or consequential
damage incurred by the Lessor for late filing or failure to file a notice of claim with the insurers.

It must declare any damage to its own insurance
company, regardless of the occurrence date and its apparent seriousness.

ARTICLE 12 - RELEASE OF THE PREMISES

12.1 LESSEES OBLIGATIONS

Regardless of the
reason for the Lessees relinquishment of the leased premises, it must return the property in a very good state of maintenance and repair and in full compliance (but only within the limits set forth in Article R 145-35 of the Commercial Code),
according to its obligations under this lease.

The same shall apply to any modifications or improvements described in Article 8 of the lease, unless the
Lessor prefers that the premises be returned in their original condition as stated in Article 8.3.

12.2 PRELIMINARY INSPECTION

No later than two (2) months prior to the Lessees departure date, a joint inspection of the premises shall be carried out in the presence of any
technician or manager appointed by both Parties. If no date is determined by mutual agreement, the Lessor shall inform the Lessee of the dates and times it will appear to inspect the premises.

At this time, any upkeep or maintenance agreements entered into by the Lessee, as well as any supporting documentation concerning maintenance or replacement
work performed during the past two years, shall be provided to the Lessor or its representatives.

At the end of this inspection, the Lessor shall send a
statement of repairs to be performed by the Lessee, as well as a list of work it requires to restore the property to its original condition and



- Page 25 of 37 -



---

replacements following any removals, without prejudice to any reservations which may be made when the property condition report is prepared upon the return of the premises.

The Lessee agrees to return the premises after full completion of the repairs, work and replacements defined above, from the moment it is required to do so
under the terms of this lease.

The Lessee shall pay an occupancy charge corresponding to the amount of the latest contractual rent increased by 50%
during the time required to perform the work, if such work continues beyond the effective date of the notice.

12.3  PROPERTY CONDITION REPORT

A check-out property condition report will be jointly prepared by the parties, in two original copies, signed and initialled by each of them, on
the date the premises are returned.

At the request of either party, this report may be prepared by a bailiff, appointed by the Lessor for this purpose at
the Lessees expense. In such case, the report will be sent by the bailiff, by registered letter with acknowledgement of receipt, to the Lessee at the address it provided during return of the premises.

If, for any reason, the Lessee does not appear on the date it was called by the Lessor, the property condition report prepared by the Lessor shall be deemed
to have been jointly prepared.

12.4 LEASEHOLD REPAIRS AND RESTORATION WORK

After retaking possession of the premises and taking into account the reservations set forth in the report prepared at that time, the Lessor shall prepare a
descriptive report and a cost estimate for the work it deems necessary, and shall notify the Lessee thereof by registered letter with acknowledgement of receipt no later than fifteen (15) days after the date the premises were returned.

Within fifteen (15) days from receipt of this notice, the Lessee must inform the Lessor if it intends to dispute the nature or cost of the work required
by the Lessor. If the Lessee does not respond upon expiry of this time period, the estimate(s) as well as the restoration work planned by the Lessor will be deemed accepted and the Lessor will have the right to have such work performed by the
companies of its choice, for which the Lessee will bear the cost, including any charges and fees for work performed by any contractor.

If the Lessee
disagrees, each party concerned shall take any action it deems necessary to reserve its rights, without prejudice to any consequences which may result from an extended inability to use the premises for this reason.

Moreover, if, whether due to this dispute or due to the performance of work under the procedures set forth above, the premises are unavailable for use beyond
the established release date (effective date of notice or of termination), daily compensation equal to the contractual rent payable upon expiry of the lease increased by 30%, as well as pro rata expenses and taxes arising from this lease, shall be
owed by the Lessee.

ARTICLE 13 - AMENDMENTS  FORBEARANCE



- Page 26 of 37 -



---

This lease can be amended only by a written document. Accordingly, in no case can an amendment be inferred from
mere forbearance by the Lessor, whether in frequency or duration, and the Lessor remains free to require strict application of the provisions and stipulations which have not been the subject of an express written amendment.

ARTICLE 14 - DECLARATION

The Lessee attests that
it has the necessary capacity to enter into this lease and declares:



| |  | that it is not insolvent or involved in compulsory liquidation, a reorganisation order, a stay of proceedings or any other process arising under applicable provisions of the Commercial Code in this event;
|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | that it is not subject to proceedings likely to result in confiscation of its property,
|- |  | ---------------------------------------------------------------------------------------



| |  | that it does not lack the legal capacity to exercise a commercial occupation.
|- |  | -----------------------------------------------------------------------------

ARTICLE 15 - TERMINATION
CLAUSE

In the event of non-payment of a single rent payment or occupancy charge (including charges and services), any supplemental rent or summary
of charges, or in the case of failure to perform any condition of this lease, this lease may be immediately terminated in the Lessors discretion, one month after an order to pay or a formal warning to comply with the terms of the lease remains
without effect.

In such case, the Lessor shall retain the security deposit and rent paid in advance, without prejudice to any damages.

All costs of the notice of default and the proceedings will be borne by the Lessee.

From the date the Lessors rights under the termination clause are deemed acquired, the occupancy charge owed until release of the property will equal
the effective contractual rent increased by 50%, in addition to expenses and taxes.

The lease shall terminate without the need for any legal formalities
by the Lessor, without prejudice to any costs or damages. No subsequent payments shall cancel the effects of this provision.

Eviction from the leased
premises may be obtained by a simple order issued by the President of the Tribunal de Grande Instance (Regional Court), on an expedited basis, finding that the termination clause is applicable.

The Lessor will regain the right to freely dispose of the premises by the mere fact of the Lessees eviction, issued by provisional order, and subsequent
offers shall not cancel the effects of this provision, without prejudice to its right to receive payment of all rent accrued or payable in advance until the acquisition date of this termination clause, the occupancy charge due thereafter under the
procedures set forth above as well as the repair costs borne by the Lessee, subject to all other amounts owed, rights and causes of action.

ARTICLE 16 - ENVIRONMENT AND SAFETY

16.1 ASBESTOS

The Lessor declares that all
investigations required by law or regulation have been conducted, and it shall make all supporting documentation available to the Lessee, especially in the event its availability is required in the scope of the improvements to be performed on the
leased premises.

16.2 TECHNOLOGICAL RISKS

In
accordance with the provisions of Articles L 125-5, R 125-23 to R 125-27 of the Environment Code regarding disclosure of the statement of natural, mining and technological risks to the new tenant, the Lessor provided such disclosure or risks to the
Lessee upon signing of this lease, who acknowledges such, including the required information concerning the building where the leased premises are located.

The Lessor further declares that, to its knowledge, the premises have not incurred any damage giving rise to payment of insurance compensation covering
natural disasters (Article L. 125-2 of the Insurance Code) or technological risks (Article L. 128-2 of the Insurance Code).

16.3 ENERGY EFFICIENCY
ANALYSIS

In addition, the energy efficiency analysis as described under Article L. 134-1 of the Building and Housing Code is also attached to this
lease. The Lessee acknowledges that it has reviewed this document.

16.4 CLASSIFIED INSTALLATIONS

If the building includes one or more installations classified for environmental protection subject to declaration or authorisation/registration, the Lessee
must comply with all recommendations and injunctions of any kind, including upgrades to the installation(s) to comply with regulations, such that the Lessor is at no time involved in this issue. In addition to maintenance work and upgrades, it must
perform at its expense all inspections and verifications required by law or regulation and, with regard to common equipment, shall bear the cost thereof.

In the event that the Lessor authorises the Lessee to install one or more pieces of equipment falling under legislation on classified installations for
purposes of its business, in addition to the paragraph above, it must also carry out the necessary administrative formalities to declare itself an operator of these classified installations, and to solely bear the cost of compliance measures and
work which the administration requires by law. The Lessee shall indemnify and hold the Lessor harmless against all liability which may result from the presence of such installations on the Premises, their use and their removal.

16.5 INSPECTIONS AND WORK BY THE LESSEE



- Page 28 of 37 -



---

16.5.1.The Lessee shall cause environmental and safety inspections to be performed at its expense, by
entities approved by the Commission Plénière des Assurances de Biens et de Responsabilité, in particular concerning the search for hazardous materials and compliance with current regulations on its improvements and any
work it may perform. The Lessee will provide the Lessor with a copy of inspection reports prepared by these organisations within one month from their receipt, specifically including any requirements, recommendations or reservations expressed as well
as any measures to be taken by the Lessee to satisfy them, including work performed. Within one month following completion of such measures, the Lessee shall provide the Lessor with a report prepared by these same organisations, validating the
measures and work carried out, it being specified that such work and/or measures must be carried out under the conditions set forth in Article 8 of the lease, and within three months following the submission of reports by the organisation, unless a
shorter period is imposed by such organisations. If the Lessee fails to perform the above mentioned measures and work within this time period, the Lessor shall have the right to have such measures and work carried out by any company of its choice,
at the Lessees expense.

16.5.2.When carrying out the work, either at the start of the lease or during possession, in addition to Article 8
of the lease, the Lessee agrees not to use any materials that may pose a danger to the safety of the occupants of the premises and/or the building.

If
the materials used by the Lessee are subsequently prohibited by a new provision, it shall immediately take personal responsibility for any consequences resulting therefrom - research, surveys, removal, compensation or otherwise - without any
recourse against the Lessor, even if such work has since become the property of the Lessor.

The Lessee shall take all necessary steps to avoid any risk
of pollution and perform all necessary remediation work at its expense.

16.6 INSPECTIONS CARRIED OUT BY THE LESSOR

During the term of the lease, the Lessee shall provide the Lessor with free access to the premises to have organisations of its choice perform any audits or
inspections, specifically concerning environmental and/or safety matters, periodic inspections of the buildings installations and equipment, and any work and measures arising therefrom. The cost of these audits and inspections, as well as the
cost of work and/or measures that must be performed subsequent to such audits and inspections, shall be borne by the Lessee, but only within the limits set forth in Article R. 145-35 of the Commercial Code. In response to its specific, occasional
requests and for its information only, the Lessor shall provide the Lessee with a copy of the inspection reports. Note that all inspections, verifications and work to which the building, improvements, installations and equipment within may be
subject under current or future regulations, particularly those concerning the safety of persons, are the Lessees full responsibility, but only within the limits set forth in Article R 145-35 of the Commercial Code, which waives any
recourse against the Lessor in this regard, specifically for the deterioration, disturbance of quiet enjoyment and financial consequences that may result therefrom.

16.7 IMPLEMENTATION OF ENVIRONMENTAL PROTECTION REGULATIONS

The Parties agree to work together in order to improve the environmental performance of the building and in order to meet the objectives and recommendations of

| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If the Parties do not reach an agreement on the choice of works and installations to carry out to improve the environmental performance of the building, the
Lessor shall be free to decide which work or installations shall be carried out that he deems pertinent to improving the buildings performance or required to meet any changes in legislation and/or the Grenelle Round Table on the Environment.

For all work and/or installations to improve the buildings environmental performance that do not fall under ordinary maintenance or replacement,
the Lessee shall be required to:

| | - |  | -----------------------------------------------------------------------



| |  |  | Bear the full costs, fees, and insurance included but only within the limits stipulated by Article R 145-35 of the French Commercial Code.

During this period, the Lessee shall pay the charges, taxes, duties, fees, services, and other receivables in the manner prescribed for this purpose in the

The rent-free period shall have no impact on the annual adjustment of the rent pursuant to the indexation

ARTICLE 7 - EARLY HANDOVER OF THE PREMISES

On an
exceptional and personal basis, the Lessor authorizes the Lessee to access the premises in advance as of April 15, 2015, solely for the purposes of preparing and conducting preparatory work as well as installing his equipment and furniture in
the leased premises (without his staff occupying them or starting operations).

This early handover shall give rise to an inventory and condition of the
property being drawn up in the presence of both Parties. This inventory shall constitute the inventory referred to under Article 7.1 of the General Conditions of the lease. The early handover of the premises shall be conducted pursuant to the costs
and conditions of this lease. However, it is hereby specified that:



| |  | the effective date of the term of the lease as stipulated in Article 2 of the Special Conditions shall occur automatically and without formality on August 1, 2015.
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



- Page 33 of 37 -



---

| |  | that the Lessee will not pay rent during the early handover period, the rent shall only become payable automatically and without formality on August 1, 2015 without prejudice to the rent-free period agreed upon in
Article 6.
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Moreover, all expenses, taxes, insurance premiums, and other additional fees related to the rent and services stipulated in this lease shall be fully payable by the Lessee during this early handover period.
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We also remind you that the Lessee must take out the insurance policies stipulated in Article 11.2 of the General Conditions to cover the
early handover period as well as all of the necessary insurance policies for carrying out the work referred to in Article 8 of the General Conditions of the lease, and must show proof by submitting an insurance certificate to the Lessor when the
initial inventory and condition of the property is being drawn up that proves the policies have been taken out and are in force from the date the early handover of the premises took place.

The Lessee shall remain liable to comply with all of the provisions contained in Article 8 of the General Conditions.

The early handover of the premises shall entail, as of its effective date, the taking of possession of the premises by the Lessee and the transfer of its
custody and risks to the Lessee for the term of the lease.

ARTICLE 8: SPECIFIC PREPARATORY WORK BY THE LESSEE

The Lessor hereby authorizes the Lessee to install an animal house for its activities of pharmaceutical research on the ground floor of the building with a
maximum surface area of 100 m2.

This authorization is given, subject to the Lessee ensuring and obtaining the administrative, hygiene, and health
permits required for this facility so that the Lessor may by no means be held liable.

If, for any reason whatsoever, the Lessee is not able to obtain the
necessary permits and/or is not able to carry out his project, he waives holding the Lessor liable.

ARTICLE 9  FEES, TAXES, AND WORK

9.3 WORK

9.3.1 Attached to this lease is a summary of the work done by the Lessor over the previous three years and its cost.

Also attached to this lease is an estimate of the work that the Lessor intends to carry out in the building over the next three years with an estimated
budget. As needed, it is hereby stipulated that this estimate, which will be updated at least every three years by the Lessor, was only prepared on a purely provisional basis and is therefore likely to be amended at any time by the Lessor which the
Lessee is fully aware of. As a result, the Lessee may not claim any reduction of rent or compensation whatsoever, nor may ask for reimbursement of expenses in the event that all or part of the proposed work is not done, as in cases where the Lessor
carries out work that was not initially planned.

9.3.2 In addition to the general conditions of this lease, it is stipulated that the Lessor shall bear
the cost of replacing all of the doors and windows and modules making up the facades of the leased property.

ARTICLE 10 - SUBLEASING - REGISTERED
ADDRESS

10.1. - Subleasing

By way of
derogation from Article 7.5 of the General Conditions of this Lease, the Lessee is authorized to partially sublease the premises to:



| |  |  | An outside company for up to a maximum of 30% of the leased areas.
| | - |  | ------------------------------------------------------------------



| |  |  | One or more of the Lessees subsidiary companies, with a maximum of 3, according to the criteria defined by Article L 233-1 of the French Commercial Code or any other text that might subsequently replace it,
up to a limit of 49% of the leased areas,
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

without the subleased areas exceeding 50% of the leased areas.

The sublease must be entered into in accordance with the law under the same terms and conditions as the master lease for a period not exceeding the master
lease.

The Lessee must justify to the Lessor, by informing him of his intention to sublease under the terms of Article L 145-31 of the French Commercial
Code, that the sublessee and the beneficiary meet the conditions required for this purpose.

Unless otherwise agreed by the Lessor, the existing legal
relationship between the sublessee and the Lessee must be maintained throughout the term of any sublease and the Lessee must justify it to the Lessor at his first request.

If the Lessor fails to participate in the document, an original copy of the contract shall be given or sent to him within a period of fifteen days from the
date it was signed.

In the event of subleasing, the Lessee shall remain solely responsible vis-à-vis the Lessor for paying the rent, expenses, and
related fees, as well as full enforcement of the conditions and obligations of the lease.



- Page 35 of 37 -



---

The Lessee shall be responsible for paying for the preparatory renovations and repair work to the leased premises
after any sublease.

The leased premises constitute an indivisible whole both materially and according to the joint intent of the Parties. The provisions
of this indivisibility clause must be reproduced in any sublease document which should therefore stipulate that by express agreement between the parties, the currently rented premises constitute an indivisible whole materially and according to the
joint intent of the Parties.

If the master lease is not renewed or in the event of the departure of the primary tenant no matter what the cause (leave,
amicable or court-ordered termination, availing oneself to the termination clause), resulting in the termination of the lease, the sublease agreement shall be terminated ipso jure. The sublessee shall not be entitled to derive any rights with regard
to the Lessor from the status of the commercial leases, and in particular from the direct right to renew the lease derived from Article L 145-32 of the French Commercial Code.

10.2. - Registered Address

As an exception and by
derogation from the General Conditions of the lease, the Lessee is authorized to register up to a maximum of 5 of his subsidiaries pursuant to the criteria stipulated by Article L 233-1 of the French Commercial Code at the leased premises or any
other text which may subsequently replace it under the following main conditions:



|a) | The Lessee agrees to ensure that the companies headquartered there strictly enforce the terms and provisions of this lease which the Lessee shall remain fully liable for vis-à-vis the Lessor.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|b) | When the Lessee leaves, the premises shall be returned unoccupied and the Lessee expressly agrees to make the companies registered at the premises make the same commitment.
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Please be reminded that this derogation is non-transferable and is exclusively granted under the main and decisive condition that the premises constitute an
indivisible whole according to the joint intent of the Parties otherwise it would not have been granted.

Furthermore, no plaque or mailbox shall be
installed displaying the names of the registered individuals.

ARTICLE 11 - SIGN

The Lessor hereby authorizes the Lessee to install a sign starting on the early handover date of the premises which is April 15, 2015.

This authorization is granted to the Lessee free of charge and no rent or royalty shall be required from the Lessee by the Lessor for this purpose.

However, it is stipulated that this authorization shall only be granted to the Lessee and validated after the technical file is submitted to the Lessor which
shows a photomontage and the proper administrative and technical authorizations, all validated by a technical control bureau for mounting, wind resistance, and studying structures.



- Page 36 of 37 -



---

The Lessee agrees to obtain the required administrative and technical authorizations before installing a sign and
shall pay for all of the taxes and/or charges related to the sign throughout the term of the lease.

In the event that the Lessee does not obtain the
authorizations referred above or is not able to install the sign no matter what the cause may be, he agrees from this point forward not to take recourse against the Lessor for this purpose.

The Lessee agrees that he shall remove the sign that he made at his own expense and liability and return the premises in their original condition upon his
departure.
