Ladies and Gentlemen:

DBV Technologies SA, a société anonyme incorporated under the laws of France (the “Company”), proposes to conduct (i) a public offering in the United States and concurrent private offering in Canada and certain other countries (collectively, the “U.S. Offering”) of ordinary shares, €0.10 nominal value per share, of the Company (the “Ordinary Shares”), which Ordinary Shares may be in the form of American Depositary Shares (“ADSs”), and (ii) a concurrent registered private placement of Ordinary Shares in France and certain other countries outside of the United States and Canada (the “International Placement”). The U.S. Offering and the International Placement are referred to collectively in this Master Underwriting Agreement (this “Agreement”) as the “Offerings.”

Citigroup Global Markets Inc., Leerink Partners LLC, Xxxxx, Garnier & Co. and Trout Capital LLC have agreed to act as underwriters for the U.S. Offering (in such capacities, the “U.S. Underwriters”), and Citigroup Global Markets Limited and Xxxxx, Garnier & Co. have agreed to act as lead managers and underwriters for the International Placement (in such capacities, the “International Underwriters” and, together with the U.S. Underwriters, the “Underwriters”). Citigroup Global Markets Inc. and Leerink Partners LLC have agreed to as representatives (the “U.S. Representatives”) of the U.S. Underwriters in connection with the U.S. Offering.

By execution of this Agreement, (i) the Company and the U.S. Underwriters are agreeing to the United States underwriting terms included as Appendix I hereto (the “U.S. Underwriting Terms”) for the U.S. Offering, and (ii) the Company and the International Underwriters are agreeing to the French guarantee terms included as Appendix II hereto (the “International Underwriting Terms” and, together with the U.S. Underwriting Terms, the “Underwriting Terms”) for the International Placement. All Ordinary Shares and ADSs to be purchased by the U.S. Underwriters, and all Ordinary Shares to be placed by the International Underwriters, pursuant to the respective Underwriting Terms, are herein called the “U.S. Shares” and the “International Shares,” respectively. The U.S. Shares and the International Shares are collectively referred to herein as the “Shares.” The Company and the Underwriters have agreed to the additional items set forth on Schedule 3 to this Agreement with respect to the conduct of the Offerings. Agreements among the Underwriters and any representations made among the Underwriters contained herein shall only be applicable to such parties and no party, including the Company, shall be deemed to be a third party beneficiary of such agreements or representations.

I.

By their execution of this Agreement, the U.S. Underwriters and the International Underwriters hereby acknowledge that (i) the U.S. Offering shall be conducted by the U.S. Underwriters pursuant to and be subject to the U.S. Underwriting Terms attached as Appendix I

1.

to this Agreement, and (ii) the International Placement shall be conducted by the International Underwriters pursuant to and be subject to the International Underwriting Terms attached as Appendix II to this Agreement. Further, it is expressly understood that those U.S. Underwriters who may only participate in the U.S. Offering by applicable law or regulation are only agreeing to the U.S. Underwriting Terms.

It is understood that two forms of prospectuses are to be used in connection with the Offerings and sale of the Shares: one form of prospectus (the “U.S. Prospectus”) relating to the U.S. Shares in the U.S. Offering, and one form of prospectus (the “International Prospectus”) relating to the International Shares, which are to be placed and sold to persons other than United States and Canadian Persons in the International Placement. The Company hereby represents and warrants to the Underwriters that there is no material difference between the U.S. Prospectus and the International Prospectus, except for (i) with respect to the U.S. Prospectus, the outside front cover page, the inside front cover page, the discussion under the headings “Risk Factors,” “Special Note Regarding Forward-Looking Statements,” “Underwriting,” “Certain Material U.S. Federal Income Tax Considerations,” “Enforcement of Civil Liabilities” and the outside back cover page, and (ii) non-material and customary information that must be inserted either pursuant to the Act or to French law, and related regulations, or customary practice, in the U.S Prospectus but not in the International Prospectus, or vice-versa.

The offering price to the public for the U.S. Offering shall be as set forth on Schedule 3 to this Agreement (the “U.S. Offering Price”). Subject to the terms and conditions and in reliance upon the representations and warranties set forth in the U.S. Underwriting Terms, the Company hereby agrees to sell to each U.S. Underwriter, and each U.S. Underwriter agrees, severally and not jointly, to purchase from the Company, the amount of U.S. Shares set forth opposite such U.S. Underwriter’s name in Schedule 1 to this Agreement. The purchase price payable by the U.S. Underwriters pursuant to the U.S. Underwriting Terms shall be $[        ] per Ordinary Share (which price shall be equivalent to €[        ] per Ordinary Share based upon the exchange rate as of the date hereof, as agreed between the U.S. Representatives and the Company).

The offering price to investors for the International Placement shall be as set forth on Schedule 3 to this Agreement (the “International Placement Price”). Subject to the terms and conditions and in reliance upon the representations and warranties set forth in the International Underwriting Terms, the Company hereby agrees to sell, and each International Underwriter agrees, severally and not jointly, to use its best efforts to have the Ordinary Shares offered by the Company purchased by investors in the International Placement. For each Ordinary Share purchased by investors in the International Placement, the International Underwriters shall be paid a commission in the amount of €[        ] per Ordinary Share. For any Ordinary Shares not subscribed as part of the International Placement, the International Underwriters agree to purchase, severally and not jointly, the percentage of the unsubscribed International Shares set forth opposite such International Underwriter’s name in Schedule 2 to this Agreement. The purchase price payable by the International Underwriters for any such unsubscribed International Shares shall be €[        ] per Ordinary Share.

By execution of this Agreement, the U.S. Underwriters and the International Underwriters agree that, for purposes of compliance with the rules and regulations of the

2.

Financial Industry Regulatory Authority (“FINRA”), the aggregate underwriting compensation to be earned by the Underwriters in connection with the Offerings shall be equal to seven percent (7%) of the aggregate gross proceeds from the Offerings, calculated as the sum of (i) the total number of shares sold in the U.S. Offering times the U.S. Offering Price, and (ii) the total number of shares sold in the International Placement times the International Placement Price.

The U.S. Underwriters and the International Underwriters further agree that, in order to provide an orderly marketing effort for the Offerings, they will consult with each other as to the availability of the Shares for sale from time to time, until the earlier of (a) notice from the U.S. Representatives to the U.S. Underwriters of the completion of the U.S. Offering and (b) notice from the International Underwriters of the completion of the International Placement. From time to time as mutually agreed among the U.S. Underwriters and the International Underwriters, the Underwriters may purchase and sell among each other such number of Shares to be purchased pursuant to the respective Underwriting Terms as may be so mutually agreed. Any Shares purchased by an Underwriter to be sold in the U.S. Offering shall be subject to the U.S. Underwriting Terms, and Shares to be sold in the International Placement shall be subject to the International Underwriting Terms.

Notwithstanding the foregoing, it is understood and agreed that the Closing Date for the transactions contemplated by the International Placement shall occur simultaneously with the “Closing Date” under the U.S. Underwriting Terms, and that the settlement date for any U.S. Option Securities (as defined in the U.S. Underwriting Terms) occurring after the Closing Date shall occur simultaneously with the settlement date under the International Underwriting Terms for any International Shares to be issued after the Closing Date.

The price and currency of settlement of any Shares so purchased or sold shall be (i) in the case of Shares to be sold in the U.S. Offering, the U.S. Offering Price, and (ii) in the case of Shares to be sold in the International Placement, the International Placement Price. Settlement with respect to any Shares transferred hereunder prior to the Closing Date (as defined in the U.S. Underwriting Terms) shall be made on the Closing Date, and in the case of purchases and sales made thereafter, as promptly as practicable but in no event later than three business days after the transfer date. The liability of the Underwriters under the respective Underwriting Terms for payment of the purchase price of the Shares purchased thereunder, and the indemnity provisions between the Company and the Underwriters in connection with the Offerings, shall not be affected by the provisions of this Agreement, but shall be governed solely by the respective Underwriting Terms.

The obligations of each U.S. Underwriter in respect of any purchase or sale of Shares under this Article I by the U.S. Underwriters shall be pro rata in accordance with the proportion of the total number of U.S. Shares that such U.S. Underwriter is obligated to purchase as set forth on Schedule 1 to this Agreement. The obligations of each International Underwriter in respect of any placement of Shares under this Article I by the International Underwriters shall be pro rata in accordance with the percentages set forth on Schedule 2 to this Agreement.

3.

II.

Each of the Underwriters represents that it is a member in good standing of FINRA or that it is a bank or dealer with its principal place of business located outside the United States, its territories and its possessions not eligible for membership in FINRA. In making sales of Shares, if it is such a member, such Underwriter agrees to comply with all applicable rules of FINRA or, if it is such a foreign bank or dealer, such Underwriter agrees to comply with the rules of FINRA as though it were such a member and NASD Rule 2420 as it applies to a nonmember broker or dealer in a foreign country.

III.

Each International Underwriter represents and agrees that, except for (x) sales between the U.S. Underwriters and the International Underwriters pursuant to Article I of this Agreement in compliance with applicable laws and (y) stabilization transactions, contemplated in Article IV of this Agreement, conducted as part of the distribution of the Shares, (a) it is not purchasing any Shares for the account of any United States or Canadian Person and (b) it has not offered or sold, and will not offer or sell, directly or indirectly, any Shares or distribute any prospectus relating to the Shares in the United States or Canada or to any United States or Canadian Person, and any dealer to whom it may sell any Shares will represent that it is not purchasing any Shares for the account of any United States or Canadian Person and will agree that it will not offer or resell any Shares directly or indirectly in the United States or Canada or to any United States or Canadian Person or to any other dealer who does not so represent and agree.

With respect to any Underwriter that is both a U.S. Underwriter and an International Underwriter, the foregoing representations and agreements made by it in its capacity as an International Underwriter shall apply only to it in its capacity as an International Underwriter. In addition, notwithstanding the foregoing representations and agreements, if an Underwriter (including its affiliates) is both a U.S. Underwriter and an International Underwriter, then the U.S. Underwriter and its corresponding International Underwriter may, with the consent of the U.S. Representatives, transfer between themselves at cost any Shares allocated to them for direct sale, so long as any Shares so transferred are treated as U.S. Shares while held by the U.S. Underwriter and International Shares while held by the International Underwriter for purposes of the foregoing representations and agreements.

“United States or Canadian Person” shall mean any national or resident of the United States or Canada, or any corporation, pension, profit sharing or other trust or other entity organized under the laws of the United States or Canada or of any political subdivision thereof (other than a branch located outside the United States and Canada of any United States or Canadian Person), and shall include any United States or Canadian branch of a person who is otherwise not a United States or Canadian Person. “United States” shall mean the United States of America, its territories, its possessions and all areas subject to its jurisdiction.

The agreements of the Underwriters set forth in the first paragraph of this Article III shall terminate upon the earlier of (a) the mutual agreement of the U.S. Representatives and the International Underwriters and (b) 30 days after the date hereof, unless the U.S. Representatives or the International Underwriters shall have given notice to the other to the effect that the distribution of the Shares by the U.S. Underwriters or the International Underwriters, as the case may be, has not yet been completed. If such notice is given, the agreements set forth in such preceding paragraph shall survive until the earlier of (x) the mutual agreement referred to in the preceding sentence and (y) 30 days after the date of any such notice.

4.

Each U.S. Underwriter represents that it has not offered or sold, and agrees not to offer or sell, any Shares, directly or indirectly, in any province or territory of Canada or to, or for the benefit of, any resident of any province or territory of Canada in contravention of the securities laws thereof and, without limiting the generality of the foregoing, represents that any offer or sale of Shares in Canada will be made only pursuant to an exemption from the requirement to file a prospectus in the province or territory of Canada in which such offer or sale is made. Each U.S. Underwriter further agrees to send to any dealer who purchases from it any of the Shares a notice stating in substance that, by purchasing such Shares, such dealer represents and agrees that it has not offered or sold, and will not offer or sell, directly or indirectly, any of such Shares in any province or territory of Canada or to, or for the benefit of, any resident of any province or territory of Canada in contravention of the securities laws thereof and that any offer or sale of Shares in Canada will be made only pursuant to an exemption from the requirement to file a prospectus in the province or territory of Canada in which such offer or sale is made, and that such dealer will deliver to any other dealer to whom it sells any of such Shares a notice containing substantially the same statement as is contained in this sentence.

The Underwriters understand that no action has been or will be taken in any jurisdiction by the Underwriters or the Company that would permit a public offering of the Shares, or possession or distribution of the U.S. Prospectus (as defined in the U.S. Underwriting Terms), in preliminary or final form, in any jurisdiction where, or in any circumstances in which, action for that purpose is required, other than the United States.

The Company hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

The Company hereby represents and warrants that the Authorized Agent has accepted such appointment and has agreed to act as said agent for service of process, and the Company agrees to take any and all action, including the filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent shall be deemed, in every respect, effective service of process upon the Company. Notwithstanding the foregoing, any action arising out of or based upon this Agreement may be instituted by any Underwriter, the directors, officers, employees and agents of any Underwriter, or by any person who controls any Underwriter, in any court of competent jurisdiction in France. The provisions of this paragraph shall survive any termination of this Agreement.

To the extent that the Company has or hereafter may acquire any immunity (sovereign or otherwise) from any legal action, suit or proceeding, from jurisdiction of any court or from set-off or any legal process (whether service or notice, attachment in aid or otherwise) with respect to itself or any of its property, the Company hereby irrevocably waives and agrees not to plead or claim such immunity in respect of its obligations under this Agreement, including the respective Underwriting Terms.

(a) Prior to the termination of the offering of the U.S. Shares, the Company will not file any amendment of the Registration Statement or the ADS Registration Statement or supplement to the U.S. Prospectus or any Rule 462(b) Registration Statement unless the Company has furnished the U.S. Underwriters a copy for their review prior to filing and will not file any such proposed amendment or supplement to which the U.S. Representatives reasonably object. The Company will cause the U.S. Prospectus, properly completed, and any supplement thereto to be filed in a form approved by the U.S. Representatives with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the U.S. Representatives of such timely filing. The Company will promptly advise the U.S. Representatives (i) when the U.S. Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement or the ADS Registration Statement shall have been filed with the Commission, (ii) when, prior to termination of the offering of the U.S. Shares, any amendment to the Registration Statement or the ADS Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, the ADS Registration Statement or any Rule 462(b) Registration Statement, or for any supplement to the U.S. Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the ADS Registration Statement or of any notice objecting to their use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Company of any notification with respect to the suspension of the qualification of the U.S. Shares for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its commercially reasonable efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement or ADS Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or the ADS Registration Statement or a new registration statement and using its commercially reasonable efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) If, at any time prior to the filing of the U.S. Prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein in the light of the circumstances under which they were made or the circumstances then prevailing not misleading, the Company will (i) notify promptly the U.S. Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to the U.S. Underwriters in such quantities as they may reasonably request.

(c) If, at any time when a prospectus relating to the U.S. Shares is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which either of the U.S. Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein in the light of the circumstances under which they were made at such time not misleading, or if it shall be necessary to amend the Registration Statement or supplement either of the U.S. Prospectus to comply with the Act or the rules thereunder, the Company promptly will (i) notify the U.S. Representatives of any such event; (ii) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 5, an amendment or supplement which will correct such statement or omission or effect such compliance; and (iii) supply any supplemented U.S. Prospectus to the U.S. Underwriters in such quantities as they may reasonably request.

(d) As soon as practicable, the Company will make generally available to its security holders and to the U.S. Representatives an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158.

(e) The Company will furnish to the U.S. Representatives and counsel for the U.S. Underwriters, without charge, signed copies of the Registration Statement and the ADS Registration Statement (including exhibits thereto) and to each other U.S. Underwriter a copy of the Registration Statement and the ADS Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by a U.S. Underwriter or dealer may be required (including in circumstances where such requirement may be satisfied pursuant to Rule 172) by the Act, as many copies of each U.S. Preliminary Prospectus, the U.S. Prospectus and each Issuer Free Writing Prospectus and any supplement thereto as the U.S. Representatives may reasonably request. The Company will pay the expenses of printing or other production of all documents relating to the offering.

(f) The Company will arrange, if necessary, for the qualification of the U.S. Shares for sale under the laws of such jurisdictions as the U.S. Representatives may reasonably designate and will use commercially reasonable efforts to maintain such qualifications in effect so long as required for the distribution of the U.S. Shares; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the U.S. Shares, in any jurisdiction where it is not now so subject.

(g) The Company will not, without the prior written consent of Citigroup Global Markets Inc., offer, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or any affiliate of the Company or any person in privity with the Company or any affiliate of the Company), directly or indirectly, including the filing (or participation in the filing) of a registration statement (other than any S-8 Registration Statement relating to the Company’s equity incentive plans) with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any Ordinary Shares or ADSs or any securities convertible into, or exercisable, or

(b) Each U.S. Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement or the ADS Registration Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act to the same extent as the foregoing indemnity to each U.S. Underwriter, but only with reference to written information relating to such U.S. Underwriter furnished to the Company by or on behalf of such U.S. Underwriter through the U.S. Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any U.S. Underwriter may otherwise have. The Company acknowledges that the statements set forth in (i) the last paragraph of the cover page regarding delivery of the U.S. Shares and under the heading “Underwriting” or “Plan of Distribution”, (ii) the list of Underwriters and their respective participation in the sale of the U.S. Shares, (iii) the sentences related to concessions and reallowances and (iv) the paragraph related to stabilization, syndicate covering transactions and penalty bids in any U.S. Preliminary Prospectus and the U.S. Prospectus constitute the only information furnished in writing by or on behalf of the several U.S. Underwriters for inclusion in any U.S. Preliminary Prospectus, the U.S. Prospectus and any Issuer Free Writing Prospectus.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the

indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel (which, if the Company is the indemnifying party, shall be limited to one such separate counsel (in addition to any local counsel) for any U.S. Underwriter together will all persons who control such U.S. Underwriter within the meaning of the Exchange Act or the Act, and no more than three such separate counsel (in addition to any local counsel) for all the U.S. Underwriters) if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent: (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include an admission of fault.

(d) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the U.S. Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Company and one or more of the U.S. Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the U.S. Underwriters on the other from the offering of the U.S. Shares. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the U.S. Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the U.S. Underwriters on the other in connection with the statements or omissions which resulted in such Losses

as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the U.S. Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the U.S. Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the U.S. Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the U.S. Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), in no event shall any U.S. Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such U.S. Underwriter with respect to the offering of the U.S. Shares exceeds the amount of any damages that such U.S. Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls a U.S. Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee, affiliate and agent of a U.S. Underwriter shall have the same rights to contribution as such U.S. Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and the ADS Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by a U.S. Underwriter. If any one or more U.S. Underwriters shall fail to purchase and pay for any of the U.S. Shares agreed to be purchased by such U.S. Underwriter or U.S. Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations hereunder, the remaining U.S. Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of U.S. Shares set forth opposite their names in Schedule 1 o the Master Agreement bears to the aggregate amount of U.S. Shares set forth opposite the names of all the remaining U.S. Underwriters) the U.S. Shares which the defaulting U.S. Underwriter or U.S. Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of U.S. Shares which the defaulting U.S. Underwriter or U.S. Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of U.S. Shares set forth in Schedule 1 to the Master Agreement, the remaining U.S. Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the U.S. Shares, and if such nondefaulting U.S. Underwriters do not purchase all the U.S. Shares, the Master Agreement will terminate without liability to any nondefaulting U.S. Underwriter or the Company. In the event of a default by any U.S. Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the U.S. Representatives shall determine in order that the required changes in the Registration Statement, the ADS Registration Statement and the U.S. Prospectuses or in any other documents or arrangements may be effected. Nothing contained herein shall relieve any defaulting U.S. Underwriter of its liability, if any, to the Company and any nondefaulting U.S. Underwriter for damages occasioned by its default under the Master Agreement.

10. Termination. The Master Agreement shall be subject to termination in the absolute discretion of the U.S. Representatives, by notice given to the Company prior to delivery of and payment for the U.S. Shares, if at any time prior to such delivery and payment (i) trading in the Company’s Ordinary Shares shall have been suspended by the Commission or Euronext or trading in securities generally on the New York Stock Exchange or the NASDAQ Stock Market shall have been suspended or limited or minimum prices shall have been established on such exchanges, (ii) a banking moratorium shall have been declared by U.S. Federal, New York State or French authorities, (iii) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States or France of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the U.S. Representatives, impractical or inadvisable to proceed with the offering or delivery of the U.S. Shares as contemplated by the U.S. Preliminary Prospectus and the U.S. Prospectus (exclusive of any amendment or supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the U.S. Underwriters set forth herein will remain in full force and effect, regardless of any investigation made by or on behalf of any U.S. Underwriter or the Company or any of the officers, directors, affiliates, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the U.S. Shares. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of the Master Agreement.

12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the U.S. Representatives, will be mailed, delivered or telefaxed to the Citigroup Global Markets Inc. General Counsel (fax no.:(000) 000-0000) and confirmed to such General Counsel at Citigroup Global Markets Inc., 000 Xxxxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx, 00000, Attention: General Counsel; or, if sent to the Company, will be mailed, delivered or telefaxed to                          and confirmed to it at Green Square-Bâtiment D, 00/00 xxx xxx Xxxxxxxx, 00000 Xxxxxxx Xxxxxx, attention of the Legal Department, with a copy to Xxxxxxx Procter LLP, 00 Xxxxx Xxxxxx, Xxxxxx, Xxxxxxxxxxxxx, 00000, Attention: Xxxxxxxx X.

APPENDIX II

INTERNATIONAL UNDERWRITING TERMS

DBV Technologies SA

Ordinary Shares (€0.10 nominal value)

Guarantee Terms

A. Reference is made to that certain Master Underwriting Agreement (the “Master Agreement”) among DBV Technologies SA, a société anonyme incorporated under the laws of France, registered with the registre du commerce et des sociétés of Nanterre under number 441 772 522, the registered office of which is Green Square – Bât. D, 00/00 xxx xxx Xxxxxxxx – 00000 Xxxxxxx, Xxxxxx (the “Company”), on the one hand, and Citigroup Global Markets Inc., Leerink Partners LLC, Xxxxx, Garnier & Co. and Trout Capital LLC (collectively, the “Underwriters”) on the other hand, pursuant to which the Company proposes to conduct (i) a public offering in the United States (the “U.S. Offering”) of ordinary shares, €0.10 nominal value per share, of the Company (the “Shares”) which Shares will be in the form of American Depositary Shares and (ii) a concurrent registered private placement of Shares in France and certain other countries (excluding the United States and Canada) ((ii) being the “International Private Placement”). These guarantee terms (the “International Underwriting Terms”) shall govern the conduct of the International Private Placement and the terms of guarantee of the issuance of the Shares and are incorporated into and expressly made a part of the Master Agreement.

B. Each of Citigroup Global Markets Inc. and Xxxxx, Garnier & Co. has agreed to act as a lead manager for the International Private Placement (each, an “International Underwriter”). Under the Master Agreement, the International Underwriters may acquire Shares from the U.S. Underwriters (as defined in the Master Agreement), subject to compliance with the provisions of the Master Agreement, and the U.S. Underwriters may acquire Shares from the International Underwriters, subject to compliance with the provisions of the Master Agreement.

C. The placement of Shares in the International Private Placement will be made in accordance with a French prospectus, comprising (i) the 2013 registration document dated April 16, 2014, registered with the French financial markets authority (the “AMF”) under number R.14-0017 (document de référence 2013), (ii) the update of the 2013 registration document of the Company dated September 22, 2014, registered with the AMF under number D.14-0286-A01 (actualisation du document de référence 2013), (iii) the operating note dated October 22, 2014, which will receive visa from the AMF on October 22, 2014 (note d’opération), (the “French Prospectus”). The French Prospectus and its riders or additions, if any, and the documents that will be incorporated by reference, and all documents, press releases, statements and opinions issued by the Company relating to the International Private Placement are hereinafter collectively referred to as the “Information Documents” and individually, an “Information Document”.

D. The distribution of Shares in the International Private Placement shall be governed by these International Underwriting Terms. In the event that all or part of the Shares are not subscribed for or purchased in the International Private Placement, such Shares would no longer be governed by the provisions of these International Underwriting Terms, but by those of the U.S. Underwriting Terms made a part of the Master Agreement and, consequently, would not be subject to the standby purchase agreement in article 1.1 below.

ARTICLE 1. Subscription guarantee

In accordance with these International Underwriting Terms, subject to the conditions set out in article 11 and in accordance with the commitments, declarations and guarantees made by the Company in article 4, the International Underwriters will make their best efforts to have up to                  Shares offered by the Company in connection with the International Private Placement (the “New Shares”) purchased by investors in France and outside of France, excluding the United States of America and Canada, at the price per Share set forth in the

1

Master Agreement (the “New Share Price”) and on the Settlement Date (as this term is defined in article 10 below). The International Underwriters will themselves acquire, at the New Share Price and on the Settlement Date (as this term is defined in Section 10 below), up to                  New Shares which have not been subscribed by investors. For this latter case, the allocation key between the International Underwriters for the acquisition of the New Shares which have not been subscribed by investors on the Settlement Date is given in Schedule 2 to the Master Agreement.

It is expressly agreed that the promise of the International Underwriters, being stipulated subject to article 12 below, shall not constitute a “performance guarantee” (garantie de bonne fin) within the meaning of article L.225-145 of the French Commercial Code.

ARTICLE 2. Order receipt and allocations

2.1 The International Underwriters have constituted an order book in which the interest issued in connection with the International Private Placement is recorded daily. The International Underwriters will apply to each order in the updated order book the criteria that they will have defined by mutual agreement. The International Underwriters have made proposals for allocation compliant with market practices. Final allocation will be determined by the International Underwriters, in consultation with the Company.

2.2 The Company shall keep confidential the information referred to in article 2.1 above concerning the identity of investors (unless they are required to disclose it pursuant to any law or regulation applicable to them or compelled to do so by a decision of a court or competent authority) and not to use such information for any purpose other than the performance of the operations hereunder.

ARTICLE 3. Distribution of the Information Documents - Restrictions on Sale

3.1 Distribution of the Information Documents

The Information Documents have not been filed or registered in any way that may make an offer to the public possible in any country. Accordingly, the International Underwriters will not use or distribute any of the Information Documents or any other document relating to the Company in a country where such use or distribution would contravene legislation or regulations, or would require prior deposit, registration or the approval of any authority.

3.2 Restrictions on Sale
