    for Commercial Use according to a specific Agreement, You and JSG have to sign
    before the Distribution of the Larger work.  You may provide warranties,
    indemnities and/or other additional terms and conditions in Your license

    incurred by the Initial Developer as a result of any such terms You offer.

    4. AVAILABILITY AND POTENTIAL MODIFICATIONS OF SOURCE CODE.

    an access to the Original Software Source Code. The Modifications of the Source
    Code that You may create or to which You may contribute, are, by nature,
    governed by the terms of this License. JSG Offering (for example, support
    services) may not cover Modifications on the Original Software otherwise than
    those explicitly accepted by JSG in a dedicated agreement as, for example, when
    those Modifications are integrated in the Original Software and therefore
    considered as a Generic Development according to the term of paragraph 12 of
    this License.

    4.2. JSG may optionally offer coverage on a Larger Work. Details of the related
    fees, payment schedule and scope of coverage have to be defined in a dedicated
    agreement signed between You and JSG.

    received by the other party during, or prior to entering into, this Agreement
    including non-public technical and business information for a period of two (2)
    years after the termination of this Agreement. This section shall not apply to
    any publicly available or independently developed information. The receiving
    party of any confidential information of the other party agrees not to use said
    confidential information for any purpose except as necessary to fulfil its
    obligations and exercise its rights under this Agreement. The receiving party
    shall protect the secrecy of and avoid disclosure and unauthorized use of the

    LIMITATION, WARRANTIES THAT THE COVERED SOFTWARE IS FREE OF DEFECTS,
    MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS
    TO THE QUALITY AND PERFORMANCE OF THE COVERED SOFTWARE IS WITH YOU. SHOULD ANY
    COVERED SOFTWARE PROVE DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER
    OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING, REPAIR OR
    CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS
    LICENSE. NO USE OF ANY COVERED SOFTWARE IS AUTHORIZED HEREUNDER EXCEPT UNDER
    THIS DISCLAIMER.

    8. LIMITATION OF LIABILITY.

    UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING
    NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL DEVELOPER, ANY OTHER
    CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED SOFTWARE, OR ANY SUPPLIER OF ANY OF
    SUCH PARTIES, BE LIABLE TO ANY PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR
    CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES
    FOR LOST PROFITS, LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER FAILURE OR
    MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH
    PARTY SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS
    LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL
    INJURY RESULTING FROM SUCH PARTY"S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
    PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR
    LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION AND
    LIMITATION MAY NOT APPLY TO YOU.

    9. U.S. GOVERNMENT END USERS.

    The Original Software is a "commercial item," as that term is defined in 48
    C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer software" (as that
    term is defined at 48 C.F.R. 252.227-7014(a)(1)) and "commercial computer
    software documentation" as such terms are used in 48 C.F.R. 12.212 (Sept. 1995).
    Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4
    (June 1995), all U.S. Government End Users acquire Covered Software with only
    those rights set forth herein. This U.S. Government Rights clause is in lieu of,
    and supersedes, any other FAR, DFAR, or other clause or provision that addresses
    Government rights in computer software under this License.

    10. TERMINATION.

    This License and the rights granted hereunder will terminate automatically if
    You fail to comply with terms herein and fail to cure such breach within 30 days
    of becoming aware of the breach. Provisions which, by their nature, must remain
    in effect beyond the termination of this License shall survive.

    The Term of this License is subject to your compliance with the term of this
    License and the payment of the appropriate fee according to JSG Offering
    considering the Commercial Use of the Software.

    11. MISCELLANEOUS.

    This License represents the complete agreement concerning subject matter hereof.
    If any provision of this License is held to be unenforceable, such provision
    shall be reformed only to the extent necessary to make it enforceable. This
    License shall be governed by the law of the jurisdiction specified in the JSG
    Terms and Conditions (except to the extent applicable law, if any, provides
    otherwise), excluding such jurisdiction"s conflict-of-law provisions. Any
    litigation relating to this License shall be subject to the jurisdiction of the
    courts located in the jurisdiction and venue specified in a notice contained
    within in the JSG Terms and Conditions, with the losing party responsible for
    costs, including, without limitation, court costs and reasonable attorney"s fees
    and expenses. The application of the United Nations Convention on Contracts for
    the International Sale of Goods is expressly excluded. Any law or regulation
    which provides that the language of a contract shall be construed against the
    drafter shall not apply to this License. You agree that You alone are
    responsible for compliance with the United States export administration
    regulations (and the export control laws and regulation of any other countries)
    when You use, distribute or otherwise make available any Covered Software.

    12. GENERIC DEVELOPMENT, APPROVED COUNTERPART, AND JOIN CONTRIBUTION

    12.1. JSG offers a counterpart, usually under the form of a free Commercial
    Right of usage of the Software attached to the payment of a subscription, in
    exchange of a Generic Developments and Your copyright assignment to JSG, when
    the related Generic Developments are financed by You, except for the co-
    development cases of join contribution (12.7)).

    12.2. The decision to accept a Generic Development as an Approved Counterpart,
    its value, the form of compensation and the criteria applied are let to the sole
    discretion of JSG.

    12.3. Description of the Approved Counterpart, its value and the type of
    compensation which shall be approved by both parties in a separated document
    provided by JSG.

    12.4. Modifications considered as Approved Counterpart are, by nature, Generic
    Developments.

    12.5. All Specific Elements, not owned by JSG and provided by You to JSG for
    Services execution, shall remain Your exclusive property when You owns the
    property of specific materials.

    12.6. All specific development, requested by You from JSG and listed on
    dedicated JSG document shall remain Your exclusive property except for the
    Generic Elements, even if these Generic Elements are developed at the same time
    as the Specific development and/or are needed by the Specific development to
    work, particularly when Generic Elements are integrated in the Original Software
    and therefore are by nature subject to the terms of the licenses used by JSG.

    12.7. Join contribution:
    As an exclusive exception to the Generic Developments definition, JSG may agree
    to accept some Modifications done by You in order to complete all - or part of -
    Generic Developments. This particular type of Generic Developments is considered
    as "Join Contributions" between You and JSG and You are considered as a
    Contributor for the related Generic Development You agreed to take in charge
    under the following rules:

    a) Contributor owns, and has sufficient rights to contribute, all source code
    and related material intended to be compiled or integrated with the source code
    for the Modifications Contributor has ever delivered, and JSG has accepted, for
    incorporation into the Covered Software.

    b) Contributor hereby assigns to JSG joint ownership in all worldwide common law
    and statutory rights associated with the copyrights, copyright application,
    copyright registration and moral rights in the Approved Counterpart to the
    extent allowable under applicable local laws and copyright conventions.
    Contributor agrees that this assignment may be submitted by JSG to register a
    copyright in the Approved Counterpart. Contributor retains the right to use the
    Approved Counterpart for Contributor's own purposes. This joint copyright
    Assignment supersedes and replaces all prior copyright assignments made by
    Contributor to JSG for the related Modifications provided by Contributor in this
    case of join contribution.

    c) Contributor grants JSG the ability to use the related Modifications he
    provided in any way with a sublicenseable, non-exclusive, irrevocable,
    worldwide, royalty-free, transferable license to relicense, use, copy, modify,
    distribute and publicly perform and display the related Modifications on any
    licensing terms (commercial or not).

    d) Contributor is legally entitled to grant the above assignment and agrees not
    to provide any Contribution that violates any law or breaches any contract.

    e) JSG may require You to submit your Modifications within a specific period of
    time. The default period is 6 months.

    f) The right to validate your Modifications as an Approved Counterpart is only
    applicable by JSG. JSG may ask for additional corrections on Your Modifications
    before definitively accepting it as an Approved Counterpart.

    g) Each party is responsible for claims and damages arising, directly or
    indirectly, out of its utilization of rights under this License and You agree to
    work with JSG to distribute such responsibility according to the Modifications
    Contributor provided. Nothing herein is intended or shall be deemed to
    constitute any admission of liability.
