     The LESSEE agrees to:

     a)   Maintain the leased premises for the entire term of the lease in a
          good state of repair and maintenance (in accordance with the condition
          report on the premises, the first of which shall be prepared on the
          date that the premises are made available, and the second of which
          shall be prepared upon the assumption of possession after completion

          days of notice addressed to the LESSEE by the LESSOR.

     d)   Inform the LESSOR or its representative as soon as possible of any
          significant repair and serious depreciation or deterioration of the

          peril, any work necessary on the leased premises, which it deems
          useful or necessary.

          When said work requires the LESSOR to perform major work, the work
          plan must be submitted for approval by the LESSEE or it
          representative.

     b)   All work of a permanent nature, changes, additions, installations,
          decorations and embellishments which the LESSEE may make to the leased
          premises during the term of the lease, as well as partitions, shall at
          the end of the lease revert to the LESSOR, unless the LESSEE elects,
          at its own cost, to return the premises to their original condition,
          excluding work that the LESSOR may have expressly approved.

     c)   The LESSEE agrees to:

          Make emergency repairs specified in Article 1724 of the Civil Code
          without decreasing the amount of the lease, even if these repairs last
          for more than forty days, and the LESSOR agrees to carry out the
          repairs as soon as possible.

          Provide for access to the premises that are the subject of this lease
          by the LESSOR, its representatives, architects, contractors and

     d)   The LESSEE likewise agrees to pay for work carried out on the public
          road or in neighboring buildings, even when it would result in
          hindering the enjoyment of the premises and without recourse against
          the Administration, the contractor of said work, the work, or the
          owners of the neighboring property, as applicable.

          The LESSOR agrees, however, to only carry out activities which may
          only be undertaken by itself as the owner, and which will restore full
          enjoyment, or provide compensation for the same.

4.3. GUARANTEE
     ---------

     The LESSEE agrees to:

     a)   only use the leased premises for the purposes set forth above in
          Article 3,

     b)   maintain the premises in a permanent state of normal and effective
          use.

     The LESSEE must be personally responsible for all the necessary
     administrative authorizations for conducting its business and for the
     payment of any amount, taxes and other fees related to the activities
     carried out on the leased premises.

4.4. SUBLEASING
     ----------

     The LESSEE may partially or fully sublet the premises to one or more of its
     affiliates or to any other companies of the group in which the LESSEE
     holds, directly or indirectly, a minimum of 10% of the capital, after
     having provided written notification to the LESSOR.

     The LESSEE may not under any circumstances sublet the entire premises to
     any sublessees aside from those specified in the preceding paragraph: it
     may sublet portions of the premises to third parties that are not companies
     in its group with the prior express written consent of the LESSOR, and by
     means of an instrument which the LESSOR shall be party to.  The LESSOR may
     only refuse its consent if the proposed sublessee does not provide
     sufficient guarantee of creditworthiness or if the work necessary to ensure
     the independence of the sublessee does not comply with regulations, or
     would adversely affect the security, the strength of the building or its
     market value. In the event of disagreements concerning the effects of work
     on the market value of the building, the LESSOR may not oppose subleasing,
     if the LESSEE agrees to return the premises to their original condition at
     the end of the lease.

4.5. ASSIGNMENT
     ----------

     The LESSEE may only assign its rights under this lease with the prior
     express written consent of the LESSOR except to a successor to its business
     and provided that the

     LESSEE remain guarantor and joint lessee of its assignee for payment of the
     rent and performance of the terms and conditions of the lease; the LESSOR
     shall be party to the

      assignment, which must be made by means of an authenticated instrument, an
      authenticated copy of which shall be delivered to it to serve as proof of
      notice thereof and which may be used for the purpose of enforcing its
      rights thereunder, failing which, this assignment must be served by extra-
      judicial instrument pursuant to Article 1690 of the Civil Code.

4.6.  GENERAL TERMS AND CONDITIONS OF ENJOYMENT

          maintenance of these signs.

          parties, the taxes for which the LESSOR may and shall be held liable,

ARTICLE 5 - RENT

5.1    This lease is granted and accepted in exchange for a base annual rent

       advance on the first day of each calendar quarter. A rent statement shall
       be sent by the LESSOR to the LESSEE fifteen days before the payment due
       date.

       agrees to pay to the LESSOR the amount of any VAT above and beyond the
       amount of the rent, or any other new tax which replaces or supplements
       the same, at the legal rate applicable on the date of each payment

       In the event that a rent payment is late, the LESSEE shall owe to the
       LESSOR, as compensation, late interest compounded daily at the average
       base bank rate plus two points, on any amount owed, fifteen days after
       prior notice is given without effect,
<PAGE>

                                       8

       without prejudice to the application of the clauses specified below under
       ARTICLE 7 "TERMINATION".

ARTICLE 6 - CONTRACTUAL INDEXING OF RENT

The rent amount specified above shall be automatically adjusted upwards or
downwards each year as from the entry into force of the lease, without any
judicial or extra-judicial formalities, on the anniversary of the effective date
of the lease, in function of the changes in the national construction cost
index, with the base index being the last known index as of the effective date
of the lease, or the index for the second quarter of 1993, the reference index
to be considered for indexing shall be the index corresponding to the second
quarter of each of the following years.

These provisions shall be a required and determining condition of this lease,
without acceptance of which the lease shall not be granted.

The parties acknowledge that the indices chosen relate directly to the purpose
of this agreement.

In the event that, for any reason whatsoever, the indices chosen above for
indexing the rent amount are no longer published, the indexing shall be
performed using as a basis either the replacement index, or a new, index chosen
by common accord between the parties. If no agreement can be reached regarding
the choice of the new index, the parties shall ask the Court of Grand Instance
of NANTERRE to rule on the matter in expedited proceedings (refere). The new
index must reflect construction costs as accurately as possible on the national
level, or in the region of Paris.

ARTICLE 7 -TERMINATION

It is expressly agreed that if payment is not made in whole or in part when due
for even a single period of rent and charges, and any accessory charges and any
legal expenses, and in the absence of any execution, and thirty days after
simple notice to pay or comply, containing mention of this clause, if the breach
is not cured, the lease shall be immediately and automatically terminated, at
the discretion of the LESSOR, even if payment is made after the aforementioned
notice term, without any other formality; a judge ruling on an expedited matter
(Juge des Referes) shall have competent jurisdiction, if necessary, to order the
eviction of the LESSEE, without prejudice to claims for all with the reservation
of damages and interest.

Any rent amount paid in advance shall be received by the LESSOR as first damages
and interest, without prejudice to any other amounts owed as a result of
LESSEE's actions.

Any procedural, legal or protective expenses, as well as any report and
notification expenses, if they are necessary, in accordance with the Law of
March 17, 1909, shall be paid by the LESSEE and shall be considered to be
supplemental and accessory charges to the rent.

ARTICLE 8  GUARANTEE

The LESSEE shall deliver to the LESSOR, within thirty days following the
effective date of the lease, a guarantee on the performance of this lease in the
form of a security deposit representing three months' rent excluding taxes,
issued by a reputable financial institution or bank, on the condition that, by
mutual agreement, this security may be replaced with any other form of guarantee
proposed by the LESSEE and deemed to be equivalent by the LESSOR.

The obligation arising from the security deposit or any other guarantee shall
remain in force during the entire term of the lease, until the final settlement
of any compensation which the LESSEE may owe to the LESSOR upon termination of
the lease and return of the premises.

If the lease is terminated, in accordance with Article 7 above, the obligation
arising from the security deposit shall remain until the final ruling or
agreement is executed by the parties.

ARTICLE 9 -  REGISTRATION

This lease shall be subject to stamp duty.

The LESSOR hereby chooses to subject its rent and fees to the value added tax;
this option releases the LESSEE from the payment of the annual registration fee
received on the amount of the rent, in accordance with Article 208 of the
General Tax Code.
