CeCILL-B 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 This Agreement is an open source software license intended to give
users significant freedom to modify and redistribute the software licensed
hereunder.

The exercising of this freedom is conditional upon a strong obligation of
giving credits for everybody that distributes a software incorporating a software
ruled by the current license so as all contributions to be properly identified
and acknowledged.

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.

   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

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

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.
