Should either Party fail to remedy any material breach of the Agreement (hereinafter “the Breaching Party”) or has not provided evidence of case of force majeure, within three (3) months of the receipt of a written notice to cure sent by the Party victim of such breach, the latter will be entitled to terminate this Agreement, as of right and without legal proceedings, by sending a written notice of termination to the Breaching Party granting a six (6) month notice period.

For the avoidance of doubt, use of the Transferred IP and Licensed IP by the Licensee outside of the Territory shall constitute a material breach for the purposes of this Agreement.

Such termination shall not relieve the Defaulting Party of its obligation under this Agreement and termination by the other Party is made without prejudice for said Party to obtain damages.

For sake of clarity, the termination date of the rights and license will be the date of expiration of the six (6) month termination notice period as of the receipt of the termination notice provided in article 12.1 (the “Termination Date”.)

(ii) By the Parties, by mutual agreement at any time;

ARTICLE 16 – MISCELLANEOUS

This Agreement is made intuitu personae with the Parties. Therefore, a Party cannot, under any circumstances, transfer this Agreement in whole or in part without prior written consent of the other Party. For the avoidance of doubt, such restriction does not apply to a Party which may freely assign all or part of its rights and obligations under the Agreement to its Affiliates. Where applicable, such Party will so notify the other Party.

Nothing contained herein shall be construed as an obligation of either Party, either express or implied, to subsequently develop, market or license the Licensed IP or Transferred IP, or any similar program(s) incorporating some or all of the functionalities contained therein.

Neither Party hereto shall be liable for any default in the performance of its obligations under this Agreement resulting from a case of force majeure as defined by French law and construed by French courts. For clarification purposes, the notification of a case of force majeure shall be made within the terms of section 17 "Notices" below.

No amendment or modification of this Agreement, or any waiver of any of its provisions, shall be effective unless in writing signed by each of the Parties

This Agreement constitutes, together with the other New IP Agreements, the entire and only agreement between the Parties with respect to its subject matter and supersedes all prior agreements, oral or written.

In the event that any provision of this Agreement is declared null and void or ineffective for any reason, the application of the remaining provisions of this Agreement shall not be affected. In such a case, the Parties undertake to negotiate in good faith in order to substitute for this stipulation a valid provision giving effect as far as possible to the intention of the Parties.

4929-5608-4338.1

The Parties agree to sign any document, provide any information and take any action (or refrain from doing so) that may be necessary or appropriate for the purposes of the execution of this Agreement, in good faith.

Nothing in this Agreement shall be construed to limit or impair any right of either Party to enter into similar agreements or arrangements with other parties, or to develop, acquire, license or market, whether directly or indirectly, other products or services, competitive to those offered by the other Party. It is specifically understood that nothing in this agreement shall constitute an obligation for a Party to use any Licensed IP, or Transferred IP at any time. For the duration of this Agreement, each Party will use its best efforts not to disclose the terms and conditions of this Agreement to any Third party without the prior written consent of the other Party, except as required by law or governmental regulations, requirements or orders, or as may be necessary to establish or assert its rights hereunder before any competent court.

This Agreement including any exhibit as well as all supplements and amendments thereto, will be executed in two copies, each of which shall be deemed an original and all of which together shall constitute one instrument.
