Bpi, agrees that it will not, directly or indirectly, (a) sell, assign, transfer (including by operation of law), lien, pledge, dispose of or otherwise encumber any of the Shares or otherwise agree to do any of the foregoing, except for a sale, assignment or transfer pursuant to the Business Combination Agreement or to another shareholder that is a party to the Company Support Agreement and bound by the terms and obligations hereof, (b) deposit any Shares into a voting trust or enter into a voting agreement or arrangement or grant any proxy or power of attorney with respect thereto that is inconsistent with this Agreement or (c) enter into any contract, option or other arrangement or undertaking with respect to the direct or indirect acquisition or sale, assignment, transfer (including by operation of law) or other disposition of any Shares; provided, that, the foregoing will not prohibit the transfer of the Shares by Bpi to an Affiliate of Bpi but only if such Affiliate executes this Agreement or a joinder agreeing to become a party to this Agreement prior to such transfer.

(c) If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law, or public policy, all other conditions and provisions of this Agreement will nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto.

(h) This Agreement, including any claims or causes of action (whether in contract, tort, or statute) that may be based upon, arise out of, or relate to this Agreement, or the negotiation, execution, or performance thereof or the Transactions, will be governed by and construed and enforced in accordance with the Laws of the State of Delaware, without giving effect to any choice or conflict of Law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware, provided, however, that notwithstanding the foregoing, the Merger, as a fusion-absorption governed by French law, and all matters relating to the corporate formalities, effectiveness and legal consequences of the Merger under French law, including the transfer of assets and liabilities of the Company to the Surviving Corporation by universal succession (transmission universelle de patrimoine), shall be governed by and construed in accordance with the laws of the Republic of France. In the event of any dispute arising out of or in connection with this Agreement, or any matters described or contemplated in this Agreement, the Parties agree that any Party may elect to first refer such dispute to non-binding mediation under the ICC Mediation Rules.

Delivery of an executed counterpart of a signature page to this Agreement by facsimile or other electronic transmission, including by e-mail attachment, will be effective as delivery of a manually executed counterpart of this Agreement.

(j) This Agreement will not be effective or binding upon Bpi until after such time as the Business Combination Agreement is executed and delivered by the Company, Parent, and Parent Merger Sub.

(k) Notwithstanding anything herein to the contrary, Bpi signs this Agreement solely in such Supporting Shareholder’s capacity as a Shareholder, and not in any other capacity and, if applicable, this Agreement will not limit or otherwise affect the actions of any affiliate, employee or designee of such Supporting Shareholder or any of its affiliates in his or her capacity as an officer or director of the Company.

(l) EACH PARTY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE, AND ENFORCEMENT OF THIS AGREEMENT AND THEREOF.
