The Company has also agreed to grant to the Underwriter an option (the “Option”) to purchase up to an additional 1,000,000 ADSs on the terms and for the purposes set forth in Section 1(b) (the “Option ADSs”). The Firm ADSs and the Option ADSs are referred to collectively herein as the “Offered ADSs.” Each reference to the Firm ADSs, the Option ADSs or the Offered ADSs herein, unless the context otherwise requires, also includes the Ordinary Shares underlying such ADSs.

The Offered ADSs will be delivered by the Depositary (as defined below), against deposit of the underlying Ordinary Shares, pursuant to the Deposit Agreement dated as of April 14, 2011 (the “Deposit Agreement”) among the Company, The Bank of New York Mellon, as depositary (the “Depositary”), and the owners and holders from time to time of the ADSs issued thereunder.

The Company confirms as follows its agreements with the Underwriter.

The Option may be exercised only to cover over-allotments in the sale of the Firm ADSs by the Underwriter and may be exercised in whole or in part at any time and from time to time on or before the 30th day after the date of this Agreement upon written notice (an “Option ADSs Notice”) by the Underwriter to the Company no later than 12:00 noon, New York City time, at least two and no more than five business days before the date specified for closing in the Option ADSs Notice (an “Option Closing Date”), setting forth the aggregate number of Option ADSs to be purchased and the time and date for such purchase. On an Option Closing Date, the Company will issue and sell to the Underwriter, and the Underwriter will purchase from the Company, the number of Option ADSs set forth in the applicable Option ADSs Notice.

2. Delivery and Payment.

Delivery of the Firm ADSs shall be made to or as instructed by the Underwriter for its account in a form reasonably acceptable to the Underwriter against payment by the Underwriter of the purchase price by wire transfer payable in same-day funds to the order of the Company at the office of ▇▇▇▇▇▇▇ & Company, LLC, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, at 10:00 a.m., New York City time, on the third (or, if the purchase price set forth in Section 1(a) hereof is determined after 4:30 p.m., New York City time, the fourth) business day after the date of this Agreement, or at such time on such other date, not later than seven business days after the date of this Agreement, as may be agreed upon by the Company and the Underwriter (such date is hereinafter referred to as the “Closing Date”).

To the extent the Option is exercised, delivery of the Option ADSs against payment by the Underwriter (in the manner specified above) will take place at the offices specified above for the Closing Date at the time and date (which may be the Closing Date) specified in the applicable Option ADSs Notice.

The Offered ADSs shall be in definitive form and shall be registered in such names and in such denominations as the Underwriter shall request at least two business days prior to the Closing Date or the applicable Option Closing Date, as the case may be, by written notice to the Company, and shall be delivered by or on behalf of the Company as instructed by the Underwriter through the facilities of The Depository Trust Company (“DTC”).

3. Representations and Warranties of the Company.

The Company represents, warrants and covenants to the Underwriter that:

(a) The Company meets the requirements for the use of Form F-3, a registration statement (Registration No. 333-182854) on Form F-3 relating to the Offered ADSs, including a base prospectus relating to the Offered ADSs (the “Base Prospectus”) and such amendments thereto as may have been required to the date of this Agreement, has been prepared by the Company under the provisions of the Securities Act of 1933, as amended (the “Act”), and the rules and regulations (collectively referred to as the “Rules and Regulations”) of the Securities and Exchange Commission (the “Commission”) thereunder, has been filed with the Commission, and has been declared effective by the Commission, and the offering of the Offered ADSs complies with Rule 415 under the Act. A final prospectus supplement to the Base Prospectus relating to the Offered ADSs and the offering thereof will be filed promptly by the Company with the Commission in accordance with Rule 424(b) of the Rules and Regulations (such final prospectus supplement, as so filed, the “Prospectus Supplement”).

Any reference herein to the Registration Statement, the Base Prospectus, a preliminary prospectus, the Prospectus Supplement, or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein, and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the

Registration Statement, the Base Prospectus, a preliminary prospectus, the Prospectus Supplement, or the Prospectus shall be deemed to refer to and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), after the time the Registration Statement initially became effective (the “Effective Date”), the date of the Base Prospectus, any preliminary prospectus, the Prospectus Supplement, or the Prospectus, as the case may be, and deemed to be incorporated therein by reference. The term “Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 of the Rules and Regulations (“Rule 433”), relating to the Offered ADSs in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g).

(b) The Company and the Depositary have prepared and filed with the Commission a registration statement relating to the ADSs on Form F-6 (No. 333-173002) and a related prospectus, which may be in the form of the ADR certificate, for registration under the Act of the ADSs evidenced by ADRs, have filed such amendments thereto and such amended prospectuses as may have been required to the date hereof, and will file such additional amendments thereto and such amended prospectuses as may hereinafter be required. The registration statement on Form F-6 for registration of the ADSs evidenced by ADRs, as amended at the time it became effective (including by the filing of any post-effective amendments thereto), and the prospectus included therein, as then amended are hereinafter called the “ADS Registration Statement.” The Form F-6 was declared effective under the Act on April 14, 2011 and (i) no stop order preventing or suspending the effectiveness of the ADS Registration Statement is in effect, and no proceedings for such purpose are pending before or, to the knowledge of the Company, threatened by the Commission, (ii) the ADS Registration Statement complies and, as amended or supplemented, if applicable, will comply in all material respects with the Act and the applicable rules and regulations of the Commission thereunder, (iii) the ADS Registration Statement, when it became effective, did not contain and, as amended or supplemented, if applicable, will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading; and (iv) all of the ADSs are registered pursuant to the ADS Registration Statement.

(c) No order preventing or suspending the use of the Base Prospectus, any preliminary prospectus, the Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus has been issued by the Commission, and no stop order suspending the effectiveness of the Registration Statement (including any related registration statement filed pursuant to Rule 462(b)) or any post-effective amendment thereto has been issued, and no proceeding for that purpose has been initiated or, to the knowledge of the Company, threatened by the Commission. On the Effective Date, on the date the Base Prospectus, any preliminary prospectus, the Prospectus Supplement, or the Prospectus is first filed with the Commission pursuant to Rule 424(b) (if required), at all times during the period through and including the Closing Date and, if later, the applicable Option Closing Date and when any post-effective amendment to the Registration Statement becomes effective or any amendment or supplement to the Prospectus is filed with the Commission, the Registration Statement and the Prospectus (as amended or as supplemented if the Company shall have filed with the Commission any amendment or supplement thereto), including the financial statements included or incorporated by reference in the Prospectus, did and will comply in all material respects with applicable provisions of the Act, the Exchange Act, the rules and regulations of the Commission under the Exchange Act (the “Exchange Act Rules and Regulations”), and the Rules and Regulations and will contain all statements required to be stated therein in accordance with the Act, the Exchange Act, the Exchange Act Rules and Regulations, and the Rules and Regulations. As of the applicable effective date as to each part of the Registration Statement, no part of the Registration Statement, the Prospectus or any such amendment or supplement thereto did or will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading.

Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Offered ADSs or until any earlier date that the issuer notified or notifies the Underwriter as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any document incorporated by reference therein that has not been superseded or modified. If there occurs an event or development as a result of which the General Disclosure Package would include an untrue statement of a material fact or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company will promptly notify the Underwriter so that any use of the General Disclosure Package may cease until it is amended or supplemented to correct such untrue statement or omission.

(b) The Company will notify the Underwriter promptly, and will confirm such advice in writing, (i) when any amendment to the Registration Statement has been filed or becomes effective or any amendment or supplement to the Prospectus has been filed, (ii) of any request by the Commission for amendments or supplements to the Registration Statement or the Prospectus or for additional information, (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or preventing or suspending the use of the Base Prospectus, any preliminary prospectus, the Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus or the initiation of any proceedings for that purpose or the threat thereof, (iv) of the happening of any event during the period mentioned in the third sentence of Section 4(e) that in the judgment of the Company makes any statement made in the Registration Statement or the Prospectus untrue or that requires the making of any changes in the Registration Statement or the Prospectus in order to make the statements therein, in the light of the circumstances in which they are made, not misleading, and (v) of receipt by the Company or any representative or attorney of the Company of any other communication from the Commission relating to the Company, the Registration Statement, any preliminary prospectus, the Base Prospectus, the Prospectus Supplement or the Prospectus. If at any time the Commission shall issue any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of the Base Prospectus, any preliminary prospectus, the Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus, the Company will make every reasonable effort to obtain the withdrawal of such order at the earliest possible moment. If the Company has omitted any information from the Registration Statement pursuant to Rule 430B of the Rules and Regulations, the Company will comply with the provisions of and make all requisite filings with the Commission pursuant to said Rule 430B and notify the Underwriter promptly of all such filings.

At the Closing Date and, as to the Option ADSs, the applicable Option Closing Date, the Accountants shall have furnished to the Underwriter a letter, dated the date of its delivery, which shall confirm, on the basis of a review in accordance with the procedures set forth in the letter from the Accountants, that nothing has come to their attention during the period from the date of the letter referred to in the prior sentence to a date (specified in the letter) not more than three days prior to the Closing Date or the applicable Option Closing Date, as the case may be, which would require any change in their letter dated the date hereof if it were required to be dated and delivered at the Closing Date or the applicable Option Closing Date, as the case may be.

(l) At the Closing Date and, as to the Option ADSs, the applicable Option Closing Date, there shall be furnished to the Underwriter a certificate, dated the date of its delivery, signed by each of the Chief Executive Officer and the Chief Financial Officer of the Company, in form and substance satisfactory to the Underwriter, to the effect that:

(ii) Each of the representations and warranties of the Company contained in this Agreement were, when originally made, and are, at the time such certificate is delivered, true and correct in all respects (in the case of any representation and warranty containing a materiality or Material Adverse Effect qualification) or in all material respects (in the case of any other representation and warranty).

(iii) Each of the covenants required to be performed by the Company herein on or prior to the date of such certificate has been duly, timely and fully performed and each condition herein required to be satisfied or fulfilled on or prior to the date of such certificate has been duly, timely and fully satisfied or fulfilled.

(s) The Company shall have furnished to the Underwriter such certificates, in addition to those specifically mentioned herein, as the Underwriter may have reasonably requested as to the accuracy and completeness at the Closing Date and the applicable Option Closing Date of any statement in the Registration Statement, the Prospectus or the General Disclosure Package, as to the accuracy at the Closing Date and the applicable Option Closing Date of the representations and warranties of the Company herein, as to the performance by the Company of its obligations hereunder, or as to the fulfillment of the conditions concurrent and precedent to the obligations hereunder of the Underwriter.

7. Indemnification.

(a) The Company will indemnify and hold harmless the Underwriter, the partners, members, directors, officers, employees, agents and affiliates of the Underwriter and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all losses, claims, liabilities, expenses and damages (including any and all investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted), to which they, or any of them, may become subject under the Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any preliminary prospectus, the Base Prospectus, the Pricing Prospectus, the Prospectus or any amendment or supplement thereto or any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations or the Marketing Materials, or the omission or alleged omission to state in such document a material fact required to be stated in it or necessary to make the statements in it not misleading in the light of the circumstances in which they were made, or arise out of or are based in whole or in part on any inaccuracy in the representations and warranties of the Company contained herein or any failure of the Company to perform its obligations hereunder or under law in connection with the transactions contemplated hereby; provided, however, that the Company will not be liable to the extent that such loss, claim, liability, expense or damage arises from the sale of the Offered ADSs in the public offering to any person by the Underwriter and is based on an untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to the Underwriter furnished in writing to the Company by the Underwriter, expressly for inclusion in the Registration Statement, any preliminary prospectus, the Base Prospectus, the Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus. The Company acknowledges that the statements set forth in the fifth, tenth, eleventh, twelfth and thirteenth paragraphs under the heading “Underwriting” in the Pricing Prospectus and the Prospectus constitute the only information relating to the

Underwriter furnished in writing to the Company by the Underwriter, expressly for inclusion in the Registration Statement, any preliminary prospectus, the Base Prospectus, the Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus. This indemnity agreement will be in addition to any liability that the Company might otherwise have.

(b) The Underwriter will indemnify and hold harmless the Company, each director of the Company, each officer of the Company who signs the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to the Underwriter, as set forth in Section 7(a), but only insofar as losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to any Underwriter furnished in writing to the Company by the Underwriter, expressly for inclusion in the Registration Statement, any preliminary prospectus, the Base Prospectus, the Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus. The Company acknowledges that the statements set forth in the fifth, tenth, eleventh, twelfth and thirteenth paragraphs under the heading “Underwriting” in the Pricing Prospectus and the Prospectus constitute the only information relating to the Underwriter furnished in writing to the Company by the Underwriter expressly for inclusion in the Registration Statement, any preliminary prospectus, the Base Prospectus, the Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus. This indemnity will be in addition to any liability that the Underwriter might otherwise have.

(c) Any party that proposes to assert the right to be indemnified under this Section 7 shall, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 7, notify each such indemnifying party in writing of the commencement of such action, enclosing with such notice a copy of all papers served, but the omission so to notify such indemnifying party will not relieve it from any liability that it may have to any indemnified party under the foregoing provisions of this Section 7 unless, and only to the extent that, such omission results in the loss of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (i) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (ii) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (iii) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party), or (iv) the indemnifying party has not in fact employed counsel reasonably satisfactory to the indemnified party to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly as they are incurred. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party. An indemnifying party will not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld or delayed).

(d) If the indemnification provided for in this Section 7 is applicable in accordance with its terms but for any reason is held to be unavailable to or insufficient to hold harmless an indemnified party under paragraphs (a), (b) and (c) of this Section 7 in respect of any losses, claims, liabilities, expenses and damages referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Company from persons other than the Underwriter, such as persons who control the Company within the meaning of the Act, officers of the Company who signed the Registration Statement and directors of the Company, who also may be liable for contribution) by such indemnified party as a result of such losses, claims, liabilities, expenses and damages in such proportion as shall be appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriter, on the other hand. The relative benefits received by the Company, on the one hand, and the Underwriter, on the other hand, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discount received by the Underwriter, in each case as set forth in the table on the cover page of the Prospectus. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company, on the one hand, and the Underwriter, on the other hand, with respect to the statements or omissions that resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriter, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 7(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss claim, liability, expense or damage, or action in respect thereof, referred to above in this Section 7(d) shall be deemed to include, for purposes of this Section 7(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7(d), the Underwriter shall not be required to contribute any amount in excess of the underwriting discount received by it and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7(d), any person who controls a party to this Agreement within the meaning of the Act will have the same rights to contribution as that party, and each officer of the Company who signed the Registration Statement will have the same rights to contribution as the Company, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against any such party in respect of which a claim for contribution may be made under this Section 7(d), will notify any such party or parties from whom contribution may be sought, but the omission so to notify will not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 7(d). No party will be liable for contribution with respect to any action or claim settled without its written consent (which consent will not be unreasonably withheld).

(e) The indemnity and contribution agreements contained in this Section 7 and the representations and warranties of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of the Underwriter, (ii) acceptance of any of the Offered ADSs and payment therefor, or (iii) any termination of this Agreement.

8. Reimbursement of Certain Expenses.

In addition to its other obligations under Section 7(a) of this Agreement, the Company hereby agrees to reimburse the Underwriter on a quarterly basis for all reasonable legal and other expenses incurred in connection with investigating or defending any claim, action, investigation, inquiry or other proceeding arising out of or based upon, in whole or in part, any statement or omission or alleged statement or omission, or any inaccuracy in the representations and warranties of the Company contained herein or failure of the Company to perform its or their respective obligations hereunder or under law, all as described in Section 7(a), notwithstanding the absence of a judicial determination as to the propriety and enforceability of the obligations under this Section 8 and the possibility that such payment might later be held to be improper; provided, however, that, to the extent any such payment is ultimately held to be improper, the persons receiving such payments shall promptly refund them.

9. Termination.

The obligations of the Underwriter under this Agreement may be terminated at any time on or prior to the Closing Date (or, with respect to the Option ADSs, on or prior to the applicable Option Closing Date), by notice to the Company from the Underwriter, without liability on the part of the Underwriter to the Company if, prior to delivery and payment for the Firm ADSs or Option ADSs, as the case may be, in the sole judgment of the Underwriter, (i) trading in any of the equity securities of the Company shall have been suspended or limited by the Commission or by the NYSE, (ii) trading in securities generally on the NYSE or the NASDAQ Stock Market shall have been suspended or limited or minimum or maximum prices shall have been generally established on such exchange, or additional material governmental restrictions, not in force on the date of this Agreement, shall have been imposed upon trading in securities generally by such exchange, by order of the Commission or any court or other governmental authority, or by the NYSE, (iii) a general banking moratorium shall have been declared by either federal or New York State or French authorities or any material disruption of the securities settlement or clearance services in the United States shall have occurred, or (iv) any material adverse change in the financial or securities markets in the United States or France or in political, financial or economic conditions in the United States or France, any outbreak or material escalation of hostilities involving the United States or France, a declaration of a national emergency or war by the United States or France, or other calamity or crisis, either within or outside the United States or France, shall have occurred, the effect of which is such as to make it, in the sole judgment of the Underwriter, impracticable or inadvisable to proceed with completion of the public offering or the delivery of and payment for the Offered ADSs.

If for any reason the purchase of the Offered ADSs by the Underwriter is not consummated or if for any reason the Company shall be unable to perform its obligations hereunder, the Company will reimburse the Underwriter for all out-of-pocket expenses (including the fees, disbursements and other charges of counsel to the Underwriter) incurred by the Underwriter in connection with the offering of the Offered ADSs.

10. No Fiduciary Relationship.

Notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriter, the Company acknowledges and agrees that (i) the purchase and sale of the Offered ADSs pursuant to this Agreement (including the determination of the terms of the offering of the Offered ADSs) is an arm’s-length commercial transaction between the Company and the Underwriter, (ii) in connection therewith and with the process leading to such transaction, the Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (iii) the Underwriter has not assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether the Underwriter has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement, (iv) the Underwriter and its affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and have no obligation to disclose or account to the Company for any of such differing interests, and (v) the Company has consulted its own legal, tax, accounting and financial advisors to the extent it deemed appropriate. The Company hereby agrees that it will not claim that the Underwriter has rendered advisory services of any nature or respect, or owe a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

11. Miscellaneous.

Notice given pursuant to any of the provisions of this Agreement shall be in writing and, unless otherwise specified, shall be mailed or delivered (a) if to the Company, at the office of the Company, 19 Le Parvis de La Défense, La ▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇▇ (facsimile: ▇▇▇ ▇ ▇▇ ▇▇ ▇▇ ▇▇), Attention: Chief Executive Officer, with a copy to ▇▇▇▇ ▇▇▇▇▇▇▇▇, Esq., ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇▇ LLP, ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇, or (b) if to the Underwriter, at the offices of ▇▇▇▇▇▇▇ & Company, LLC, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: Corporate Finance Department, with a copy to ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, Esq. and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, Esq., ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ LLP, ▇▇▇▇ ▇▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇. Any such notice shall be effective only upon receipt. Any notice under Section 9 may be made by telecopier or telephone, but if so made shall be subsequently confirmed in writing.

This Agreement has been and is made solely for the benefit of the Underwriter, the Company and the controlling persons, directors and officers referred to in Section 7, and their respective successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. The term “successors and assigns” as used in this Agreement shall not include a purchaser, as such purchaser, of Offered ADSs from the Underwriter.

This Agreement and any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement (“Claim”), directly or indirectly, shall be governed by, and construed in accordance with, the laws of the State of New York.

Except as set forth below, no Claim may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have exclusive jurisdiction over the adjudication of such matters, and the Company consents to the jurisdiction of such courts and personal service with respect thereto. The Company hereby irrevocably waives any objection to the venue of a proceeding in any such court and consent to personal jurisdiction, service and venue in any court in which any Claim arising out of or in any way relating to this Agreement is brought by any third party against any Underwriter or any indemnified party. The Company hereby irrevocably designates GKL Corporate/Search, Inc., ▇▇▇ ▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ as agent upon whom process against the Company may be served. The Underwriter and the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its securityholders and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The Company agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the Company and may be enforced in any other courts to the jurisdiction of which the Company is or may be subject, by suit upon such judgment.

In respect of any judgment or order given or made for any amount due hereunder that is expressed and paid in a currency (the “judgment currency”) other than United States dollars, the Company will indemnify the Underwriter against any loss incurred by such Underwriter as a result of any variation as between (a) the rate of exchange at which the United States dollar amount is converted into the judgment currency for the purpose of such judgment or order and (b) the rate of exchange at which the Underwriter is able to purchase United States dollars with the amount of the judgment currency actually received by the Underwriter. The foregoing indemnity shall constitute a separate and independent obligation of the Company and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “rate of exchange” shall include any premiums and costs of exchange payable in connection with the purchase of or conversion into United States dollars.

This Agreement may be signed in two or more counterparts with the same effect as if the signatures thereto and hereto were upon the same instrument.

In case any provision in this Agreement shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Each of the Company and the Underwriter hereby waives any right it may have to a trial by jury in respect of any claim based upon or arising out of this Agreement or the transactions contemplated hereby.

Please confirm that the foregoing correctly sets forth the agreement among the Company and the Underwriter.

The undersigned is a holder of securities of Sequans Communications S.A., a société anonyme incorporated in the French Republic (the “Company”), and wishes to facilitate the public offering of American Depositary Shares (“ADSs”), each representing one ordinary share, nominal value €0.02 per share (the “Ordinary Shares”), of the Company (the “Offering”). The undersigned recognizes that such Offering will be of benefit to the undersigned.

In consideration of the foregoing and in order to induce you to act as underwriters in connection with the Offering, the undersigned hereby agrees that, during the period commencing as of the effective date of the Underwriting Agreement to be entered into in connection with the Offering and ending on the date that is ninety (90) days after the date of the final Prospectus Supplement relating to the Offering (the “Lock-Up Period”), the undersigned will not, without the prior written approval of ▇▇▇▇▇▇▇ & Company, LLC, directly or indirectly, (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of any ADS or Ordinary Share or any securities convertible into or exercisable or exchangeable for ADSs or Ordinary Shares or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the ADSs or Ordinary Shares, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of ADSs or Ordinary Share or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) issuances of securities solely made in connection with exercises of outstanding equity awards of the Company, provided that any ADSs or Ordinary Shares received upon such exercise will be subject to the trading restrictions discussed above, (b) forfeitures of ADSs or Ordinary Shares to cover taxes due upon the vesting of restricted stock pursuant to the terms of restricted stock agreements, (c) a transfer of ADSs or Ordinary Shares or securities convertible into, or exercisable or exchangeable for ADSs or Ordinary Shares to immediate family members, family partnerships, or trusts, the only partners or beneficiaries of which are the undersigned and /or a member of his or her immediate family, or (d) transfers upon the death of the undersigned to his or her executors, legatees or beneficiaries or a bona fide gift; provided that, in the case of any transfers pursuant to clauses (c) and (d) above, each transferee or donee agrees to be bound in writing by the terms of this Agreement prior to such transfer.
