orders, and in particular, all work affecting hygiene and safety, even in the

against THE LESSOR:

- -- in case of interruption or malfunction of the various services in the
building;

- -- in case of theft, looting, destruction or other criminal acts committed in
the leased premises; in particular, THE LESSOR does not assume any obligation of
surveillance.

caused by third parties, and agrees to be solely responsible for legal action to
be taken against the latter; THE LESSOR subrogates him in his rights in this
regard.

term of the lease, his furniture, equipment, windows, installations against
risks of fire, explosions, water damage, and the recourses of neighbours or

indemnities due to THE LESSEE by any insurance companies in case of claims, for

THE LESSEE shall be responsible for the payment of water, electricity,
telephone, etc.

(0)12) RESTAURANT

intercompany restaurant, which in this case is indicated in the "Specific Terms
and Conditions," such restaurant will be made available to tenants for the
service of meals to be eaten on site by their employees, excluding any other
use. However, the initial opening will be dependent upon the needs expressed by
all the users; THE LESSOR shall remain the sole judge as to the advisibility of
its opening.

Upon the execution of this lease, THE LESSEE automatically becomes a member of
the Association or of the Group that will manage the restaurant. He agrees to
maintain his membership for the entire duration of his occupancy and to perform
all obligations, notably financial, incumbent upon him as a member. He shall
comply with the specific provisions of the internal regulation of the building
that apply to the restaurant.

applicable, in his capacity as a member of the Association or the Group:

1--to use the restaurant according to its purpose as defined above;

2--to be solely responsible for the operation of the company restaurant; 
consequently, he shall establish the internal regulation determining the 
terms and conditions of its use by his personnel, and enter into all 
necessary contracts, notably the contract with the restaurateur and all 
appropriate insurance contracts; in all cases, THE LESSEE shall 

                                      -7-





be the only one to assume the entire responsibility of all
damage which might be caused to people or property, while using or after having
used the restaurant, without having the right to trouble or sue THE LESSOR in
this regard; THE LESSEE expressly waives any recourse against THE LESSOR.

3--to bear all expenses relating to equipment of any nature necessary for the
restaurant's operation, including that which may become a fixture, even though
they may have to be replaced completely, because of normal wear and tear, Acts
of God or any other cause.

5--to bear the share of expenses related to the space that comprises the
restaurant, and all related taxes, expenses, and costs, including property
taxes.

In the event of vacancy of all or part of the office space belonging to the
above-mentioned building, other than that covered by this lease, the total
amount of expenses of the restaurant resulting from the above-mentioned
obligations shall be borne by its only user or users, so that THE LESSOR does
not have to bear any.

An inventory of the premises shall be drawn up prior to the start of operations
after due hearing of THE LESSEE (or the Association or the Group) and THE
LESSOR.

13) VISIT OF THE PREMISES

LESSOR to visit the leased premises, at any moment, to ensure their good
condition, and shall provide any vouchers that might be requested from him to
prove the proper performance of the terms and conditions of the lease, and
without those visits being abusive, provided he be given, except in cases of
emergency, at least one (1) week's notice.

In the six (6) months preceding the expiration of the lease, THE LESSEE shall
allow visits of the leased premises, on all business days from 9:00 a.m. to
11:00 a.m. and from 2:00 p.m. to 5:00 p.m., by any person authorized by THE
LESSOR. During this same period, he shall allow THE LESSOR to install a notice
or a sign to indicate that the space is for rent.

(0)ARTICLE 5--FINANCIAL TERMS AND CONDITIONS OF THE LEASE

1) RENT

The rent is due as of the effective date of the lease.

a) ANNUAL BASE RENT

(0)This lease is granted and accepted for an annual rent exclusive of tax, the
amount of

                                      -8-





which is set forth hereinafter in the "Specific Terms and Conditions."

This rent shall be payable in installments equal to one quarter of the said
amount, for each quarter and in advance, on the first day of the first month of
each calendar quarter.

The rent pertaining to the period comprised between the effective date of the
lease and the expiration of the calendar quarter that is ongoing at such date,
shall be paid on the effective date of the lease.

THE LESSOR agrees that the value added tax will be levied on revenues from this
lease.

Such tax shall be borne by THE LESSEE who agrees to pay it to THE LESSOR at the
same time as the corresponding rental payment, exclusive of tax, and to bear any
tax that may be substituted or added to the VAT by regulation.

In the event of non-payment when due of the entire amount of the rent, the
corresponding VAT, or the expenses, THE LESSEE shall owe to THE LESSOR a
compensation equal to 1.50% plus taxes, per month or per fraction of month in
arrears. This compensation, calculated on the amount of the unpaid sum when due,
shall be due automatically, without prior demand letter, and its payment shall
not constitute an extension in favour of THE LESSEE.

(0)b)  INDEXATION OF ANNUAL RENT

The annual rent shall be adjusted according to the National Construction Cost
Index (INDICE NATIONAL DU COUT DE LA CONSTRUCTION), published quarterly by the
INSEE (National Institute of Statistics and Economic Studies).

The index used for the calculation of the annual base rent is indicated in the
"Specific Terms and Conditions."

Consequently, the annual rent shall automatically be adjusted each year on the
anniversary of the effective date of the lease in the same direction and the
same proportion as the variation, from one year to the other, of the index of
that same quarter.

In the event of the late publication of the index, the rent shall be calculated
in the interim according to the last published index.

The variation of the rent shall be automatic; it shall not be subordinated to
any notification; the fact that it is not calculated immediately shall in no way
cancel the right of either of the parties to request at a later date that it be
applied retroactively.


                                      -9-






If the INSEE index ceases to be published, it shall be replaced, if no official
index is available, by an equivalent index chosen either by amiable agreement
between the parties, or if there is no agreement between them, through expertise
executed by only one expert, appointed either jointly by the parties or by order
of the President of the High Court, upon request of the most diligent party; the
fees relating to the expertise and to the legal proceedings shall be borne
exclusively THE LESSEE. The expert shall act as common agent for both parties in
accordance with Article 1592 of the Civil Code, the provisions of which have
been extended to renting.

This indexation clause constitutes an essential and determining clause without
which THE LESSOR would not have entered into this lease. Consequently, its
partial or total non-application shall authorize THE LESSOR, and him only, to
request the termination of the lease, without compensation.

(0)2) CHARGES

THE LESSEE shall bear all expenses, charges, services, supplies, taxes, and
expenses relating to the leased premises, including, in particular, property
taxes and, if the premises are located in the region of Ile-de-France, the tax
on office space instituted by Article 40 of the rectified law of Finance for
1989, as well as the fees of the management firm and/or the manager, and the
insurance premiums of the building.

In the event, however, that THE LESSOR has to pay any amounts because of THE
LESSEE, the latter shall reimburse the former without delay upon his first
request.

The charges usually incumbent upon THE LESSOR but transferred contractually to
THE LESSEE are, for tax purposes, assimilated to the rent as a supplement.
Consequently, the VAT shall be added to them.

(0)THE LESSEE shall paY THE LESSOR, with each quarterly rent, an advance payment
on charges calculated according to the estimated expenses for the year. They
shall be adjusted afterwards according to the definitive statement of the
expenses relating to the leased premises. The amount of the advance payment
shall be readjusted, each year, according to the evolution of the charges. The
first quarterly advance payment is set in the "Specific Terms and Conditions."

(0)3) SECURITY DEPOSIT

THE LESSEE has paid upon the execution of this lease, as a security deposit, to
THE LESSOR, who acknowledges it, an amount equal to three (3) months' rent
inclusive of tax; such amount is indicated in the "Specific Terms and
Conditions."

The security deposit shall be used, at the expiration of the lease or if it is
terminated earlier for any cause whatsoever, to pay any amounts that might be
owed by THE LESSEE to THE LESSOR; it is specified that THE LESSEE shall in no
case use this

                                      -10-





deposit to pay rent or other charges.

At the time of the annual adjustment of the rent, the security deposit shall be
increased or decreased, so as to always correspond to three (3) months of rent
inclusive of tax. The increases on the payments, or the reimbursements, shall be
paid upon first request.

In the event of termination of this lease due to non-performance by THE LESSEE
of any of his obligations, the security deposit shall be kept by THE LESSOR as
compensation, without prejudice to his right to the payment of the accrued rent
and the rent that will accrue until the end of the current quarterly period, and
of repairs incumbent upon THE LESSEE, and subject to damages that might be due
to THE LESSOR.

ARTICLE 6--TERMINATION

It is expressly agreed that failure to pay when due any one quarterly rental
payment, corresponding VAT, or charges, or failing to perform any of the other
provisions of the lease, this lease shall be automatically terminated, at THE
LESSOR's choice, without any need to have such termination ordered by a court,
one month after an order to pay or a demand letter has been served and remained
unfulfilled.

THE LESSOR shall redeem possession of the premises by the simple eviction of THE
LESSEE, pronounced by provisional order, and no later offers may end the effect
of this clause, and without prejudice to his right to payment of the accrued
rent and rent that will accrue until the end of the current quarterly period,
and of the cost of repairs incumbent upon THE LESSEE, and subject to any other
amounts due, rights or actions.

(0)ARTICLE 7--GUARANTEES

They are indicated and set forth in the "Specific Terms and Conditions."

ARTICLE 8--REGISTRATION

This deed shall be registered at THE LESSOR's request and at THE LESSEE's
expense.

ARTICLE 9--

ARTICLE 11--CHOICE OF RESIDENCE AND JURISDICTION OF COURTS

                                      -11-





For the purposes of the performance of this lease, THE LESSOR chooses his head
office as his residence and THE LESSEE chooses his head office as his residence.

THE PARTIES AGREE THAT ALL DISPUTES RELATING TO THIS DEED SHALL BE SUBJECT TO
THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE HEAD OFFICE OF THE LESSOR.
