CeCILL-C FREE SOFTWARE LICENSE AGREEMENT Notice

This Agreement is a Free Software license agreement that is the result
of discussions between its authors in order to ensure compliance with
the two main principles guiding its drafting:

   * firstly, compliance with the principles governing the distribution
   of Free Software: access to source code, broad rights granted to users,

   * secondly, the election of a governing law, French law, with which
   it is conformant, both as regards the law of torts and intellectual
   property law, and the protection that it offers to both authors and
   holders of the economic rights over software.

The authors of the CeCILL¹ license are:



   Commissariat à l'Energie Atomique - CEA, a public scientific,
   technical and industrial research establishment, having its principal
   place of business at 25 rue Leblanc, immeuble Le Ponant D, 75015
   Paris, France.



   Centre National de la Recherche Scientifique - CNRS, a public
   scientific and technological establishment, having its principal
   place of business at 3 rue Michel-Ange, 75794 Paris cedex 16, France.



   Institut National de Recherche en Informatique et en Automatique -
   INRIA, a public scientific and technological establishment, having
   its principal place of business at Domaine de Voluceau, Rocquencourt,
   BP 105, 78153 Le Chesnay cedex, France.

   Preamble The purpose of this Free Software license agreement is to
   grant users the right to modify and re-use the software governed by
   this license.

   The exercising of this right is conditional upon the obligation to
   make available to the community the modifications made to the source
   code of the software so as to contribute to its evolution.

   In consideration of access to the source code and the rights to copy,
   modify and redistribute granted by the license, users are provided
   only with a limited warranty and the software's author, the holder of
   the economic rights, and the successive licensors only have limited
   liability.

   In this respect, the risks associated with loading, using, modifying
   and/or developing or reproducing the software by the user are
   brought to the user's attention, given its Free Software status,
   which may make it complicated to use, with the result that its use is
   reserved for developers and experienced professionals having in-depth
   computer knowledge. Users are therefore encouraged to load and test
   the suitability of the software as regards their requirements in
   conditions enabling the security of their systems and/or data to
   be ensured and, more generally, to use and operate it in the same
   conditions of security. This Agreement may be freely reproduced and
   published, provided it is not altered, and that no provisions are
   either added or removed herefrom.

   This Agreement may apply to any or all software for which the holder
   of the economic rights decides to submit the use thereof to its
   provisions.

      modified or unmodified Software to third parties according to the
      terms and conditions set forth hereinafter.

         5.3.1. DISTRIBUTION OF SOFTWARE WITHOUT MODIFICATION

         The Licensee is authorized to distribute true copies of the
         Software in Source Code or Object Code form, provided that said
         distribution complies with all the provisions of the Agreement
         and is accompanied by:

            1. a copy of the Agreement,

            2. a notice relating to the limitation of both the Licensor's

      that shall govern its distribution under the conditions defined
      in Article 5.3.3.

      6.4 NOTICE OF RIGHTS

      The Licensee expressly undertakes:

         1. not to remove, or modify, in any manner, the intellectual
         property notices attached to the Software;

         2. to reproduce said notices, in an identical manner, in the
         copies of the Software modified or not;

         3. to ensure that use of the Software, its intellectual property
         notices and the fact that it is governed by the Agreement is
         indicated in a text that is easily accessible, specifically
         from the interface of any Derivative Software.

      The Licensee undertakes not to directly or indirectly infringe the
      intellectual property rights of the Holder and/or Contributors on
      the Software and to take, where applicable, vis-à-vis its staff,
      any and all measures required to ensure respect of said intellectual
      property rights of the Holder and/or Contributors.

   Article 7 - RELATED SERVICES

      7.1 Under no circumstances shall the Agreement oblige the Licensor
      to provide technical assistance or maintenance services for the
      Software.

      However, the Licensor is entitled to offer this type of
      services. The terms and conditions of such technical assistance,
      and/or such maintenance, shall be set forth in a separate
      instrument. Only the Licensor offering said maintenance and/or
      technical assistance services shall incur liability therefor.

      7.2 Similarly, any Licensor is entitled to offer to its licensees,
      under its sole responsibility, a warranty, that shall only be
      binding upon itself, for the redistribution of the Software and/or
      the Modified Software, under terms and conditions that it is free
      to decide. Said warranty, and the financial terms and conditions
      of its application, shall be subject of a separate instrument
      executed between the Licensor and the Licensee.

   Article 8 - LIABILITY

      8.1 Subject to the provisions of Article 8.2, the Licensee shall
      be entitled to claim compensation for any direct loss it may have
      suffered from the Software as a result of a fault on the part of
      the relevant Licensor, subject to providing evidence thereof.

      8.2 The Licensor's liability is limited to the commitments made
      under this Agreement and shall not be incurred as a result of in
      particular: (i) loss due the Licensee's total or partial failure
      to fulfill its obligations, (ii) direct or consequential loss
      that is suffered by the Licensee due to the use or performance
      of the Software, and (iii) more generally, any consequential
      loss. In particular the Parties expressly agree that any or all
      pecuniary or business loss (i.e. loss of data, loss of profits,
      operating loss, loss of customers or orders, opportunity cost, any
      disturbance to business activities) or any or all legal proceedings
      instituted against the Licensee by a third party, shall constitute
      consequential loss and shall not provide entitlement to any or
      all compensation from the Licensor.

   Article 9 - WARRANTY

      9.1 The Licensee acknowledges that the scientific and technical
      state-of-the-art when the Software was distributed did not enable
      all possible uses to be tested and verified, nor for the presence
      of possible defects to be detected. In this respect, the Licensee's
      attention has been drawn to the risks associated with loading,
      using, modifying and/or developing and reproducing the Software
      which are reserved for experienced users.

      The Licensee shall be responsible for verifying, by any or all
      means, the suitability of the product for its requirements, its
      good working order, and for ensuring that it shall not cause damage
      to either persons or properties.

      9.2 The Licensor hereby represents, in good faith, that it is
      entitled to grant all the rights over the Software (including in
      particular the rights set forth in Article 5).

      9.3 The Licensee acknowledges that the Software is supplied "as
      is" by the Licensor without any other express or tacit warranty,
      other than that provided for in Article 9.2 and, in particular,
      without any warranty as to its commercial value, its secured,
      safe, innovative or relevant nature.

      Specifically, the Licensor does not warrant that the Software is
      free from any error, that it will operate without interruption, that
      it will be compatible with the Licensee's own equipment and software
      configuration, nor that it will meet the Licensee's requirements.

      9.4 The Licensor does not either expressly or tacitly warrant
      that the Software does not infringe any third party intellectual
      property right relating to a patent, software or any other property
      right. Therefore, the Licensor disclaims any and all liability
      towards the Licensee arising out of any or all proceedings
      for infringement that may be instituted in respect of the use,
      modification and redistribution of the Software. Nevertheless,
      should such proceedings be instituted against the Licensee, the
      Licensor shall provide it with technical and legal assistance
      for its defense. Such technical and legal assistance shall be
      decided on a case-by-case basis between the relevant Licensor
      and the Licensee pursuant to a memorandum of understanding. The
      Licensor disclaims any and all liability as regards the Licensee's
      use of the name of the Software. No warranty is given as regards
      the existence of prior rights over the name of the Software or as
      regards the existence of a trademark.

   Article 10 - TERMINATION

      10.1 In the event of a breach by the Licensee of its obligations
      hereunder, the Licensor may automatically terminate this Agreement
      thirty (30) days after notice has been sent to the Licensee and
      has remained ineffective.

      10.2 A Licensee whose Agreement is terminated shall no longer be
      authorized to use, modify or distribute the Software. However,
      any licenses that it may have granted prior to termination of the
      Agreement shall remain valid subject to their having been granted
      in compliance with the terms and conditions hereof.

   Article 11 - MISCELLANEOUS

      11.1 EXCUSABLE EVENTS

      Neither Party shall be liable for any or all delay, or failure
      to perform the Agreement, that may be attributable to an event
      of force majeure, an act of God or an outside cause, such as
      defective functioning or interruptions of the electricity or
      telecommunications networks, network paralysis following a virus
      attack, intervention by government authorities, natural disasters,
      water damage, earthquakes, fire, explosions, strikes and labor
      unrest, war, etc.

      11.2 Any failure by either Party, on one or more occasions,
      to invoke one or more of the provisions hereof, shall under no
      circumstances be interpreted as being a waiver by the interested
      Party of its right to invoke said provision(s) subsequently.

      11.3 The Agreement cancels and replaces any or all previous
      agreements, whether written or oral, between the Parties and having
      the same purpose, and constitutes the entirety of the agreement
      between said Parties concerning said purpose. No supplement or
      modification to the terms and conditions hereof shall be effective
      as between the Parties unless it is made in writing and signed by
      their duly authorized representatives.

      11.4 In the event that one or more of the provisions hereof
      were to conflict with a current or future applicable act or
      legislative text, said act or legislative text shall prevail, and
      the Parties shall make the necessary amendments so as to comply with
      said act or legislative text. All other provisions shall remain
      effective. Similarly, invalidity of a provision of the Agreement,
      for any reason whatsoever, shall not cause the Agreement as a
      whole to be invalid.

      The Agreement is drafted in both French and English and both
      versions are deemed authentic.

   Article 12 - NEW VERSIONS OF THE AGREEMENT

      who reserve the right to periodically publish updates or new
      versions of the Agreement, each with a separate number. These
      subsequent versions may address new issues encountered by Free
      Software.

      12.3 Any Software distributed under a given version of the Agreement
      may only be subsequently distributed under the same version of
      the Agreement or a subsequent version.
