(b) Should the Offeror notify to the Sellers’ Representative a New Schedule 4.3(a)(iv) within the above-mentioned timeframe, such New Schedule 4.3(a)(iv) shall, with effect from (and including) the date of such notice, automatically supersede Schedule 4.3(a)(iv) to the Securities Purchase Agreement as appended as of the date hereof, so that any reference to Schedule 4.3(a)(iv) to the Securities Purchase Agreement shall be construed as a reference to the New Schedule 4.3(a)(iv), which the parties to this Letter expressly acknowledge and agree. With effect from (and including) the date of such notice, Schedule 4.3(a)(iv) to the Securities Purchase Agreement as appended as of the date hereof shall be modified, restated and replaced in its entirety by New Schedule 4.3(a)(iv), which the parties to this Letter expressly acknowledge and agree.

(c) The parties to this Letter hereby agree that should the Offeror notify to the Sellers’ Representative a New Schedule 4.3(a)(iv) within two (2) Business Days of the receipt of an Exercise Notice, such New Schedule 4.3(a)(iv) shall be appended to the execution version of the Securities Purchase Agreement on the Signing Date.

13. EXERCISE OF THE PUT OPTION - EXECUTION OF THE SECURITIES PURCHASE AGREEMENT

(a) If the Sellers decide to exercise the Put Option, the Sellers’ Representative shall do so on behalf of all the Sellers by notifying the Offeror and the Purchaser in writing of the Sellers’ decision between the Exercise Period Opening Date (included) and the Expiry Date (included) (the "Exercise Notice"), in the form attached to this Letter as Schedule 2.

(b) The Exercise Notice shall specify the date (being a Business Day no sooner than the fifth (5^th) Business Day and no later than the tenth (10^th) Business Day after the date on which the notice was sent) on which the Securities Purchase Agreement is to be executed, unless the Offeror and the Sellers’ Representative agree in writing on another date prior to or on such date (either of such dates, the "Signing Date"), and the time and location in Paris at which the Securities Purchase Agreement is to be executed, unless otherwise agreed in writing by the Sellers’ Representative and the Offeror prior to or on the Signing Date.

(c) In any case, subject to the sending of the Exercise Notice between the Exercise Period Opening Date (included) and the Expiry Date (included) and subject to the terms of this Letter (and, in particular, subject to the terms of Clauses 3(b), 9(b) and 12), we irrevocably undertake to procure that the Purchaser executes, and the Purchaser hereby irrevocably undertakes to execute the Securities Purchase Agreement, and we irrevocably undertake to execute the Securities Purchase Agreement for the sole purpose of Section 11.4 of the Securities Purchase Agreement, on the Signing Date, at the time and location specified in the Exercise Notice, or at such other time and/or location as may be agreed upon in writing by the Sellers’ Representative and the Offeror prior to or on the Signing Date.

-12-

(d) We acknowledge that as of the date hereof, the Sellers accept the benefit of the Put Option without undertaking to exercise it. Until the Sellers’ Representative’s exercise of the Put Option on behalf of all the Sellers, the Sellers will therefore not be committed to sell the Transferred Securities to the Purchaser and will not be bound by any obligation in connection with the Transaction.

(e) In connection with the significant amount of fees and expenses incurred by the Offeror on behalf of the Purchaser and/or by the Purchaser since the beginning of our discussions for the purposes of evaluating the Transaction and preparing this Letter (together with its Schedules), the Sellers hereby undertake, individually and not jointly (conjointement mais non solidairement), to reimburse to the Purchaser (or to the Offeror or to such other Affiliate of the Offeror and within such proportions as the Purchaser and the Offeror may jointly notify to the Sellers’ Representative for such purpose), within thirty (30) calendar days of, where applicable, the Expiry Date or the Signing Date, those fees and expenses, in a maximum aggregate amount of five millions Euros (€5,000,000) and provided that the relevant supporting documents are provided to the Sellers’ Representative, each of them within the limit of its Portion (as such term is defined below) of such fees and expenses, (A) should the Sellers’ Representative (on behalf of all the Sellers): (i) refuse any proposition by the Offeror to postpone the date mentioned in Clause 1(a)(ii) pursuant to Clause 1(b) by at least one (1) month, where the Exercise Period Opening Date may not occur before March 31, 2016 for a reason beyond the Offeror’s control; or (ii) decide, as is the Sellers’ right, not to exercise the Put Option on behalf of all the Sellers between the Exercise Period Opening Date (included) and the Expiry Date (included), provided that the Offeror has complied with all of its material obligations hereunder, or (B) should any Seller or Xxxxxx M2 not proceed with the execution of the Securities Purchase Agreement on the Signing Date, in the event that the Put Option is exercised by the Sellers’ Representative on behalf of all the Sellers between the Exercise Period Opening Date (included) and the Expiry Date (included). For the avoidance of doubt, it is expressly specified that in the event that the Put Option and this Letter terminate at the date mentioned in Clause 1(a)(ii) (as postponed pursuant to (A)(i) above, as the case may be) in accordance with Clause 1(b) above prior to the occurrence of the Exercise Period Opening Date for any reason beyond the Sellers’ control, the Sellers shall not be liable for any reimbursement of fees and expenses whatsoever.

For the purpose of the preceding paragraph, "Portion", when used with respect to a Seller, shall mean the fraction having for numerator, the portion of the Adjusted Enterprise Value (as such term is defined below) which would have been allocable to the Transferred Securities (other than the Mezzanine Bonds, if any) owned by such Seller by application of the provisions of Section 2.9 of the Securities Purchase Agreement (i) as if the Final Price was equal to the Enterprise Value (without any net cash or working capital adjustment), (ii) as of, where applicable, the Expiry Date or the Signing Date and (iii) by using the foreign exchange rate of Euros converted into US Dollars as of, where applicable, the Expiry Date or the Signing Date, as determined on the basis of the Euro foreign exchange reference rate of the European Central Bank as updated by 3 p.m. C.E.T. on, where applicable, the Expiry Date or the Signing Date, and for denominator, the Adjusted Enterprise Value.

For the purpose of the preceding paragraph, "Adjusted Enterprise Value" shall mean the Enterprise Value less the value as of, where applicable, the Expiry Date or the Signing Date, of the Mezzanine Debt, as converted from Euros into US Dollars by using the foreign exchange rate of Euros converted into US Dollars as of, where applicable, the Expiry Date or the Signing Date, as determined on the basis of the Euro foreign exchange reference rate of the European Central Bank as updated by 3 p.m. C.E.T. on, where applicable, the Expiry Date or the Signing Date.

The parties to this Letter expressly acknowledge and agree that notwithstanding anything to the contrary in this Letter, the provisions of this Clause 13(e) shall survive any termination of

-13-

this Letter, (A) should the Sellers’ Representative (on behalf of all the Sellers): (i) refuse any proposition by the Offeror to postpone the date mentioned in Clause 1(a)(ii) pursuant to Clause 1(b) by at least one (1) month, where the Exercise Period Opening Date may not occur before March 31, 2016 for a reason beyond the Offeror’s control; or (ii) decide, as is the Sellers’ right, not to exercise the Put Option on behalf of all the Sellers between the Exercise Period Opening Date (included) and the Expiry Date (included), provided that the Offeror has complied with all of its material obligations hereunder, or (B) should any Seller or Xxxxxx M2 not proceed with the execution of the Securities Purchase Agreement on the Signing Date, in the event that the Put Option is exercised by the Sellers’ Representative on behalf of all the Sellers between the Exercise Period Opening Date (included) and the Expiry Date (included).

(f) Subject to the provisions of Clause 13(e) above, each party to this Letter shall be responsible for payment of all fees and costs incurred by it or on its behalf in connection with the negotiation, preparation and signing of this Letter (and its Schedules) and the consummation of the transactions contemplated hereby, including the fees and disbursements of its financial advisors, accountants and attorneys.

(g) In any case, each party to this Letter agrees to be bound by the specific commitments expressly made by it under this Letter, as the case may be.

(h) Subject to the sending by the Sellers’ Representative of the Exercise Notice between the Exercise Period Opening Date (included) and the Expiry Date (included) and subject to the terms of this Letter (and, in particular, subject to the terms of Clauses 3(b), 9(b) and 12), Xxxxxx M2 hereby irrevocably undertakes to execute, and the Sellers undertake to procure that Xxxxxx M2 executes, the Securities Purchase Agreement for the sole purpose of Sections 5.1 to 5.5, 5.9 and 5.12 of the Securities Purchase Agreement on the Signing Date, at the time and location specified in the Exercise Notice, or at such other time and/or location as may be agreed upon in writing by the Sellers’ Representative and the Offeror prior to or on the Signing Date.

14. MANAGEMENT SINCE THE DATE HEREOF

(a) As from the date hereof (included) and until (and including) the actual date of execution of the Securities Purchase Agreement (or, failing the delivery of an Exercise Notice, the Expiry Date, or, in case of termination of this Letter in accordance with the provisions of Clauses 3(b), 9(b) and 12, the date of receipt by the Sellers’ Representative of the termination notice served by the Offeror), except as may be (x) required by applicable Laws or any Governmental Authority, or (y) expressly contemplated in this Letter or in the Securities Purchase Agreement, or (z) consented to in writing by the Offeror and the Purchaser (which consent shall not be unreasonably withheld or delayed, having due consideration for the interests of the Group Companies and ManCo), the Sellers and ManCo, within the limits of their respective authority as shareholder, officer, director or employee of the Target Companies, undertake to:

(i) procure that the Target Companies will carry on their activities only in the ordinary course of business, with due care and attention as bon père de famille (de façon xxxxxxxx, diligente et soigneuse) and in substantially the same manner as heretofore conducted, so as to preserve in all material respects their businesses and their relationships with Third Parties including their customers; and

(ii) without limiting the general scope of paragraph (i) above, prevent each of the Group Companies and ManCo from taking or committing to take any of the actions set forth in Sections 5.9(b)(i) to 5.9(b)(xxiv) of the Securities Purchase Agreement.

-14-

(b) For the purposes of granting any consents which may be requested by the Sellers' Representative, a Group Company or ManCo pursuant to this Clause 14, the Offeror and the Purchaser hereby designate Xx. Xxxxxx Bar with immediate effect and represent and warrant to, and agree with, the Sellers' Representative, each of the Sellers and Xxxxxx M2 that Xx. Xxxxxx Bar shall have full capacity and right to give any such consents on behalf of the Offeror and the Purchaser during the term of this Letter. Within three (3) Business Days of receipt of any request for consent by the Sellers' Representative, a Group Company or ManCo, Xx. Xxxxxx Xxx, on behalf of the Offeror and the Purchaser, shall have the right to notify the Sellers' Representative, the relevant Group Company or ManCo that the Offeror and the Purchaser object to the proposed action (which notice of objection shall indicate their reasons for so objecting). If Xx. Xxxxxx Xxx, on behalf of the Offeror and the Purchaser, shall not have notified the Sellers' Representative, the relevant Group Company or ManCo, as the case may be, of the objection of the Offeror and the Purchaser to a proposed action within such period of three (3) Business Days, the Offeror and the Purchaser shall be deemed to have consented to such proposed action.

15. ACCESS TO THE TARGET COMPANIES

Re: Project Tahoe - Exercise Notice

Dear Sirs,

Reference is made to the offer letter dated December 7, 2015 entered into by and between the Offeror, the Purchaser, Xxxxxx M2 and the Sellers (the "Put Option Agreement"). Capitalized terms in this letter (the "Exercise Notice") shall, unless otherwise defined herein, have the meanings ascribed to them in the Put Option Agreement.

In accordance with the provisions of Clauses 1, 9, 11, 12, 13, 19 and 22 of the Put Option Agreement, we hereby:

(i) Notify the Offeror and the Purchaser of the Sellers’ decision to exercise the Put Option;

(ii) Confirm to the Offeror and the Purchaser that:

• the IP Agreement has been duly executed by Xxxxxx and France Brevets and a certified copy of the IP Agreement duly executed by Xxxxxx and France Brevets has been provided to the Offeror and the Purchaser, in both cases on or prior to the date hereof;

• the Information and Consultation Process has been fully completed and evidence thereof has been provided to the Offeror and the Purchaser, in both cases on or prior to the date hereof;

• the provisions of paragraphs (a) and (b) of Clause 5 of the Put Option Agreement have been definitively complied with and evidence thereof has been provided to the Offeror and the Purchaser, in both cases on or prior to the date hereof;

• as of the date hereof, save for what has been set forth in the Securities Purchase Agreement or notified pursuant to Clause 9(a) of the Put Option Agreement as constituting or being likely to constitute a Material Adverse Change, no circumstance, event or fact has occurred since the Reference Date that constitutes or would be likely to constitute a Material Adverse Change;

• pursuant to Clause 9(a)(ii) of the Put Option Agreement, the Offeror and the Purchaser will be promptly notified of the occurrence (or non-occurrence) between the date hereof (included) and the actual date of execution of the Securities Purchase Agreement (included) of any event, the occurrence (or non-occurrence) of which constitutes or would be likely to constitute a Material Adverse Change;

• as of the date hereof, no Permitted Transfer has been completed in breach of Clause 10 prior to or on the Signing Date;

• pursuant to Clause 10, no Permitted Transfer will be completed from the date hereof (included); and

• pursuant to Clause 11, should the Offeror notify to the Sellers’ Representative a New Schedule 4.3(a)(iv) within two (2) Business Days of the receipt of this Exercise Notice, such New Schedule 4.3(a)(iv) will, with effect from (and including) the date of such notice, automatically supersede Schedule 4.3(a)(iv) to the Securities Purchase Agreement as appended as of the date of the Put Option Agreement, so that any reference to Schedule 4.3(a)(iv) to the Securities Purchase Agreement will be construed as a reference to the New Schedule 4.3(a)(iv). With effect from (and including) the date of such notice, Schedule 4.3(a)(iv) to the Securities Purchase Agreement as appended as of the date of the Put Option Agreement will be modified, restated and replaced in its entirety by New Schedule 4.3(a)(iv) and therefore we confirm that the New Schedule 4.3(a)(iv) will be appended to the execution version of the Securities Purchase Agreement on the Signing Date.

(iii) Specify that the Securities Purchase Agreement is to be executed on [•], 2016, unless the Sellers’ Representative and the Offeror agree in writing on another date prior to or on such date, and at [•] [a.m./p.m.] (Paris time), at the offices of Shearman & Sterling LLP, 000, xxxxxx xxx Xxxxxx-Xxxxxxx, 00000 Xxxxx (Xxxxxx), unless otherwise agreed between the Sellers’ Representative and the Offeror in writing prior to or on the Signing Date.

Pursuant to Clause 22 of the Put Option Agreement, this Exercise Notice and any contractual or non-contractual obligation arising out of or in connection with this Exercise Notice shall be governed by, and construed in accordance with, French law. All disputes arising out of or in connection with this
