11. Surrendering Possession of the Premises

Before moving and prior to any even partial removal of furniture and equipment, Lessee must first have settled all lease payments and incidental rental charges, and provide evidence via receipts of payment of taxes
and duties incumbent thereupon for past years as well as for the current year.

Lessee shall, by and before the expiration date of the lease at the latest,
surrender the premises leased in good state of repair, as acknowledged by an inventory of fixtures pursuant to which Lessee shall hand over the keys to Lessor. This inventory of fixtures, set at a date to be jointly determined by the Parties, shall
include, where applicable, the statement of repairs to be carried out. Notwithstanding the fact that the keys have been handed over, the lease shall continue until the expiration date, with lease payments remaining due until that date. Failing this,
the inventory of fixtures shall be drawn up on the expiration date of the lease.

Should Lessee be absent on the date and at the time scheduled for the
inventory of fixtures, the inventory may be drawn up  at Lessors discretion  in the presence of a bailiff who may be assisted by a locksmith to enter the premises, with Lessee bearing all expenses appurtenant thereto.

etc.) within the month following such amendment, and shall inform Lessor as prescribed by article 1690 of the French Civil Code regarding any full or partial merger. In the event of a partial merger, the contributing company shall continue to
assume joint and several liability and guarantee with respect to the merger beneficiary, for the payment of lease and charges and for fulfillment of the terms and conditions of the lease.

ARTICLE VI  FINANCIAL OBLIGATIONS

1. Rent

The rent set in accordance with the special terms and conditions set forth below is a decisive clause for
both parties to enter this Lease Agreement. This lease is granted and accepted in exchange for an annual rent, base value, for an amount stipulated hereinbelow in Article VIII-6 and shall evolve according to legal provisions and in keeping
with the terms and conditions prescribed in Article VI-6 hereinbelow.

2. Incidental Rental Charges

Lessee shall refund Lessor or any legal entity designated by the latter for the share applicable to the premises leased in view of common services, insurance policies,
real estate tax, rental tax, individual supplies, expenses necessary for functioning, cleaning and maintenance and for repairs on the building complex and, in particular, all expenses related to maintenance and repair of elevators, heating,
courtyards, roofing and garden areas, as well as all improvements, furniture, and equipment for operating the common areas; Lessee shall likewise refund the share of salaries and wages for all charges appurtenant to all personnel assigned to the
building, such as guards, cleaning staff, administrative staff as well as standing cash advances called up by the property administrators, fees for the building manager, etc. All the above so that the rent stipulated below is net of all charges for
Lessor.

This refund shall be made by drawing on a quarterly provision paid by Lessee with each rental payment. In order to take into account fluctuations
in charges, Lessor may modify the amount of provisions for charges upon presentation of documentary evidence.

At the end of each annual period, the amount
of provisions paid up shall be adjusted according to the annual statement of account.

3. Taxes and Duties

Since Lessor has opted for said rent to be subject to value-added tax, in keeping with article 260-2 of the French General Code of Taxation, value-added tax shall be
added to the aforementioned rent and incidental rental charges at the applicable rate on the date of invoice.

4. Terms of Payment

Lessee shall pay to Lessor rent and incidental rental charges in four equal installments maturing on the thirty-first (31st) day of March, the thirtieth (30th) of June, the thirtieth (30th) of September, and the first (1st) of December of each year.

All payments shall be made at Lessors domicile or at any other location indicated by Lessor.



Page 10 of 20



---

In the event of late payment of rent due by Lessee or late payment of any other amount due under this Lease Agreement and
that has not be paid up within the required time period, Lessor shall receive, as of right and eight (8) days after serving formal notice in advance but to no avail, lateness interest calculated at a rate of one point fifty percent
(1.50%) per month as of the maturity date, with each month started being considered as a full month.

5. Security Deposit

In order to guarantee performance of its obligations, Lessee shall pay to Lessor, who acknowledges such, an amount representing SIX (6) months of rent excluding
taxes, by way of a security deposit. This security deposit shall neither bear interest nor be deductible from the last rental payment and shall be refundable after Lessees departure, provided that (i) all amounts due to be paid by Lessee
and especially the outstanding balance of charges corresponding to Lessees occupancy period are fully settled and (ii) refurbishment works on the premises leased have been paid up.

In the event of any revision or change in the rental price stipulated above, this security deposit shall be readjusted proportionately to the new rent, and under the
same terms and conditions.

In the event of termination of this Lease Agreement pursuant to non-fulfillment of these terms and conditions for any reason
whatsoever that may be ascribed to Lessee, said security deposit shall be vested in Lessor as per initial compensatory damages without prejudice to any other compensatory damages.

Upon Lessees departure, the security deposit shall first be deducted from the amount of repairs due by Lessee as specified in Article V-11.

6. Indexation Clause

Furthermore, rent shall be subject to the following indexation clause: rent shall vary
automatically each year in proportion to changes in the quarterly construction cost index published by the French National Institute for Statistical and Economic Studies (INSEE). For the first year, the index stipulated in Article VIII-8 shall be
compared with the index for the same quarter in the following year.

For subsequent years, the index chosen for the previous reappraisal shall be compared
with the index for the same quarter in the following year.

In the event that this index is not known at the anniversary date of the Lease Agreement,
indexing shall be done provisionally based on the last known index.

It is hereby stipulated that this clause entails indexing by agreement between the
Parties. As a result, the statutory triennial revision currently prescribed by articles 26 and 27 of the French decree dated 30 September 1953 shall continue to apply at all times.

Should the index referred to in this Article no longer be published by the French National Institute for Statistical and Economic Studies, the Parties shall refer to any other publication of the index chosen as
provided by a public or private body chosen by joint agreement between the Parties. Failing such an agreement between the Parties, the index shall be designated by the Presiding Magistrate of the Commercial Court of Paris.

Should the Parties fail to agree on the choice of expert, an expert shall be appointed by the Landlord/Tenant court at
the request of the earliest petitioner.

ARTICLE VII  OTHER OBLIGATIONS

1. Termination Clause

It is hereby agreed between the Parties that should Lessee fail to fulfill a single obligation
or any terms and condition of the Lease Agreement or to punctiliously pay each rent and all incidental rental charges at due date, this Lease Agreement shall be terminated by Lessor as it sees fit, as of right and without any judicial formality, one
(1) month after serving, to no avail, formal notice to comply or a mere order to pay notified to the person or served at the place of domicile and containing Lessors statement of its intention to avail itself of this clause.

Should Lessee refuse to vacate the premises, it shall be forced to do so forthwith by mere order handed down in summary proceedings by the Court of First Instance at
the location where the building is situated. This order will be provisionally enforceable and without guarantee notwithstanding appeal. In this event, and whatever the ground for termination, the security deposit referred to in Article VIII-7 shall
remain vested in Lessor as per initial compensatory damages without prejudice to any other compensatory damages.

2 Occupancy of the Premises
after Cessation or Termination of the Lease

In the event that, after cessation or termination of the lease, the premises are not returned wholly
unoccupied to Lessor on the day agreed upon, the occupancy indemnity due by Lessee or its successors in title until the surrender of possession and payable for each day due, shall be equal to the last rent plus fifty percent (50%). Charges shall
also be due until the day Lessee returns the premises to Lessor. All the foregoing provisions are without prejudice to any other compensatory damages, save for a special agreement between the Parties.

3. Expenses

All expenses, duties and fees appurtenant hereto, as
well those resulting from or that are the consequence of the Agreement, namely all expenses incurred by Lessor (fees for lawyers, bailiff, etc.) pursuant to actions duly taken against Lessee in order to obtain performance of the clauses and terms
and conditions of the Agreement shall be borne by Lessee who expressly pledges to abide by this commitment.

3. Domicile

In view of the performance hereof, Lessors place of domicile shall be its head office and Lessees place of domicile shall be the premises leased.

Pursuant to the foregoing provisions, the security deposit shall be revised upwards to reach 1,512,450 French francs,
since the Lessee has agreed to increase the security deposit to six (6) months of lease exclusive of tax.

Article 2  Lease Renewal

The Parties agree to supplement Article 2 entitled Durationin the Commercial Lease Agreement signed on 7 August 1991 as
follows:

Upon expiration of the nine (9) year period, namely on 1 November 2000, the lease shall be renewed for successive three-year
periods unless either Party serves prior notice by extrajudicial deed at least six (6) months before the expiration of each period.

In
light of the above, the Parties agree that rent for the lease thus renewed is hereby set at 2,621,580 French francs exclusive of tax and service charge.

The security deposit shall be readjusted so as to constantly be equal to six (6) months of rent excluding tax and shall therefore amount to 1,310,790 French francs.

The rent thus stipulated shall be indexed in accordance with the provisions laid down in the Commercial Lease Agreement dated 7 August 1991.

The Parties agree on the base index set out below:



| |  |  | INSEE index for the first quarter of 1997: 1047.
| | - |  | ------------------------------------------------

The lease shall
otherwise continue based on the same charges, terms and conditions as stipulated in the Commercial Lease Agreement dated 7 August 1991.

Article
3  Termination Clause

The Lessor represents and warrants, and the Lessee expressly agrees thereto, that the terms and conditions governing
the renewal of the lease as stipulated hereinabove in Article 2 are an essential and decisive provision without which the Lessor would not have agreed to decrease the rent set hereinabove in Article 1.

In pursuance, this Amendment shall be terminated as of right and without any formality or indemnity for either Party should the Lessee waive the renewal of the
Commercial Lease Agreement dated 7 August 1991 at the maturity date on 1 November 2000.

Where appropriate, any differential in rent with regards
to the rent stipulated in the Commercial Lease Agreement dated 7 August 1991 and the rent granted for the period covering 1 October 1997 to 1 November 200 shall become due and payable at the end of the lease agreement.

All other charges, terms and conditions in the initial Commercial Lease Agreement remain unchanged.
