Ladies and Gentlemen:

Valneva SE, a Societas Europaea incorporated under the laws of France (the “Company”), proposes, subject to the terms and conditions stated in this agreement (this “Agreement”), to issue and sell to the underwriters named in Schedule I-1 (the “US

Underwriters”) and in Schedule I-2 (the “European Underwriters”) hereto (together, the “Underwriters”) for whom you are acting as representatives (the “Representatives”) an aggregate of (i) [•] American Depositary Shares (the “Firm ADSs”) representing [•] Ordinary Shares, nominal value €0.15 per share (the “Ordinary Shares”) and (ii) [•] Ordinary Shares (the “Firm Shares”, and, together with the Firm ADSs, the “Firm Securities”). The Company also grants to the Underwriters acting severally and not jointly, the option described in Section 2 hereof to purchase, at the election of the Underwriters, (i) up to [•] additional American Depositary Shares representing [•] Ordinary Shares (the “Option ADSs”) and (ii) no Ordinary Shares (the “Option Shares”, and together with the Option ADSs, the “Option Securities”). The Firm ADSs and the Option ADSs are collectively called the “ADSs”, and the Firm Shares and the Option Shares are collectively called the “Shares”. Unless the context requires otherwise, each reference to the Firm ADSs, the Option ADSs or the ADSs herein also includes the Ordinary Shares underlying the ADSs (the “Underlying Shares”).

The Offered Securities will be issued by way of a capital increase without preferential rights for existing shareholders reserved to categories of investors under the provisions of Article L.225-138 of the French Commercial Code, pursuant to the 17^th resolution of the Company’s combined general shareholders’ meeting held on June 23, 2021. Each prospective investor of Offered Securities shall have executed an investor letter in the form set forth as Exhibit A or Exhibit B hereto, as applicable.

Goldman Sachs Bank Europe SE (“Goldman Sachs”) and Jefferies LLC (“Jefferies”) have agreed to act as representatives of the several Underwriters with respect to the U.S. Offering (as defined below) (in such capacity, together the “U.S. Representatives”), and Goldman Sachs, Jefferies International Limited and Jefferies GmbH have agreed to act as representatives of the several Underwriters with respect to the European Offering (as defined below) (in such capacity, together the “European Representatives”) in connection with the offering and sale of the Offered Securities. The U.S. Representatives and the European Representatives are collectively called the “Representatives.” The division of services between Jefferies International Limited and Jefferies GmbH shall be determined at Jefferies’ absolute discretion, whereby regulated services with respect to EU 27 countries and EU 27 investors shall be undertaken by Jefferies GmbH only. To the extent there are no additional underwriters listed on Schedule A, the term “Representatives” as used herein shall mean you, as Underwriters, and the term “Underwriters” shall mean either the singular or the plural, as the context requires. It is understood that the obligations of the Underwriters contained in this Agreement shall not constitute a performance guarantee (garantie de bonne fin) within the meaning of Article L. 225-145 of the French Commercial Code.

The ADSs are to be issued pursuant to a deposit agreement (the “Deposit Agreement”), dated as of May 10, 2021 among the Company, Citibank, N.A., as depositary (the “Depositary”), and the holders and beneficial owners from time to time of the American Depositary Receipts (the “ADRs”) issued thereunder by the Depositary and evidencing the ADSs. Each ADS represents the right to receive two Ordinary Shares deposited pursuant to the Deposit Agreement (the “Underlying Shares”).

The Company understands that the Underwriters propose to conduct a global offering of Ordinary Shares to specified categories of investors (the “Reserved Offering”)

comprised of (i) a public offering of Firm ADSs and Option ADSs, as the case may be, to be delivered in the form of ADSs in the United States, Canada and certain countries outside of Europe (the “U.S. Offering”) and (ii) a concurrent offering of Firm Shares [and Option Shares] outside of the United States and Canada, to institutional investors, including to “qualified investors” within the meaning of Article 2(e) of the Regulation 2017/1129/EU, as amended (the “Prospectus Regulation”) in France and other member states of the European Union (the “European Offering”).

The Company has prepared and filed with the French Financial Markets Authority (Autorité des marchés financiers) (the “AMF”) a universal registration document filed with the AMF on April 9, 2021 under number D.21-0286 (the “URD”) as amended by the first amendment filed with the AMF on October [•], 2021 under number D.21-[•] (the “Amendment to the URD” and together with the URD, the “Universal Registration Document”).

The Company has also published (i) the press release announcing the availability of the Amendment to the URD dated [•], 2021 (the “Amendment Press Release”), (ii) the launch press release, in French and in English, announcing the main terms and conditions of the Reserved Offering dated [•] (the “Launch Press Release”) and (iii) the English language corporate presentation, dated [•], published on the Company’s website (the “Corporate Presentation” and together with the Universal Registration Document, the Amendment Press Release and the Launch Press Release, the “Disclosure Materials”).

All references in this Agreement to the Universal Registration Document shall be deemed to refer collectively to (i) the URD, when such reference is made as of a date or for a period at which or during which the Amendment to the URD has not yet been filed with the AMF, and (ii) after such filing, to the URD and the Amendment to the URD, taken together.

“Pricing Press Release” means the press release, in French and in English, to be issued by the Company immediately after the execution of this Agreement and announcing the results of the Offering including the pricing of the share capital increase (together with the Launch Press Release, the “Offering Press Releases”).

For the avoidance of doubt, all references in this Agreement to the Disclosure Materials shall be deemed to refer to the Universal Registration Document, the Amendment Press Release and the Corporate Presentation and, when published, the Offering Press Releases.

The Company hereby grants to the Underwriters the right to purchase at their election up to [•] Option Securities, at the purchase price per ADS or per Ordinary Share set forth in the paragraph above, for the sole purpose of covering sales of ADSs or Ordinary Shares in excess of the number of Firm ADSs or Firm Shares, provided that the purchase price per Option ADS or per Option Share shall be reduced by an amount per ADS or per Ordinary Share equal to any dividends or distributions declared by the Company and payable on the Firm ADSs or Firm Shares but not payable on the Option Securities. Such election to purchase Option Securities may be exercised only by written notice from the Representatives to the Company, given within a period of 30 calendar days after the date of this Agreement, setting forth the aggregate number of Option Securities to be purchased and the date on which such Option Securities are to be delivered, as determined by the Representatives but in no event earlier than the First Time of Delivery (as defined in Section 4 hereof) or, unless the Representatives and the Company otherwise agree in writing, earlier than two or later than ten business days after the date of such notice. The Representatives and the Company, by mutual consent, may determine that all or a portion of the Option Shares be delivered in the form of ADSs and that all or a portion of the Option ADSs be delivered as Ordinary Shares, and payment therefor shall be made in U.S. Dollars or Euros, as the case may be.

3. Upon the authorization by the Representatives of the release of the Firm ADSs and the Firm Shares, the several Underwriters propose to offer the Firm ADSs and the Firm Shares for sale upon the terms and conditions set forth in the Pricing Prospectus, the Prospectus and the Offering Press Releases.

(a) The ADSs to be purchased by each Underwriter hereunder, in definitive or book-entry form, and in such authorized denominations and registered in such names as the Representatives may request upon at least forty-eight hours’ prior notice to the Company shall be delivered by or on behalf of the Company to the Representatives, through the facilities of the Depository Trust Company (“DTC”), for the account of such Underwriter, against payment by or on behalf of such Underwriter of the purchase price therefor by wire transfer of Federal (same-day) funds to the account specified by the Company to the Representatives at least forty-eight hours in advance. The Company will cause the certificates, if any, representing the Firm Securities to be made available for checking and packaging at least twenty-four hours prior to the Time of Delivery (as defined below) with respect thereto at the office of DTC or its designated custodian (the “Designated Office”).

At least one full business day prior to the First Time of Delivery, the Company shall have taken all actions and provided the Registrar with all notices, documents, corporate authorizations or other instruments necessary or required to effectuate the issuance of the certificat du dépositaire referred herein.

Delivery of the Offered ADSs and/or the ADRs evidencing Offered ADSs shall be made through the facilities of the Depository Trust Company (“DTC”) unless the applicable Representatives shall otherwise instruct. Prior to the First Time of Delivery, the Company shall have taken all actions and made all necessary filings with Euronext and Euroclear France, and with the Depositary and DTC, to facilitate the transfer of the Offered Shares through Euroclear France and the Offered ADSs through DTC. The ADRs evidencing the Offered ADSs shall be registered in such names and denominations as the applicable Representatives shall have requested at least one full business day prior to the applicable Time of Delivery.

(e) As compensation for the Underwriters’ commitments, the Company shall pay, or cause the Registrar to pay, to Goldman Sachs as Representative of the Underwriters for purposes of settlement and delivery of the Offered Securities, a commission equal to the sum of (a) the product of $[•] and the number of Firm ADSs (and/or Option ADSs, as the case may be) to be issued at the applicable Time of Delivery and (b) the product of €[•] and the number of Firm Shares (and/or Option Shares, as the case may be) to be issued at the applicable Time of Delivery. The aforementioned commissions shall be deducted from the gross proceeds payable to the Company as of the applicable Time of Delivery and shall be paid on such date by the Registrar to the Underwriters as soon as possible after issuance of the certificat du dépositaire pursuant to Section 4(c) hereof. The Company irrevocably agrees to such transfer.

9. (a) The Company will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or the Disclosure Materials, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, any “roadshow” as defined in Rule 433(h) under the Act (a “roadshow”), any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act or any Testing-the-Waters Communication, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or the Disclosure Materials, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus or any Testing-the-Waters Communication, in reliance upon and in conformity with the Underwriter Information.

(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or the Offering Press Releases, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any roadshow or any Testing-the-Waters Communication, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or the Offering Press Releases, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any roadshow or any Testing-the-Waters Communication, in reliance upon and in conformity with the Underwriter Information; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred. As used in this Agreement with respect to an Underwriter and an applicable document, “Underwriter Information” shall mean the written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the information contained in the [•] paragraph under the caption “Underwriting”.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; provided that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under the preceding paragraphs of this Section 9 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under the preceding paragraphs of this Section 9. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any documented legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution

may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party, in form and substance reasonably satisfactory to such indemnified party, from all liability arising out of such action or claim 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 any indemnified party.

(d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the ADSs and the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party 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 the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other 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 commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include 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 subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the ADSs and the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such 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. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company under this Section 9 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each employee, officer and director of each Underwriter and each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer or other affiliate of any Underwriter; and the obligations of the Underwriters under this Section 9 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act.

10. (a) If any Underwriter shall default in its obligation to purchase the ADSs or the Shares which it has agreed to purchase hereunder at a Time of Delivery, the Representatives may in their discretion arrange for the Representatives or another party or other parties to purchase such ADSs or Shares on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such ADSs or Shares, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such ADSs or Shares on such terms. In the event that, within the respective prescribed periods, the Representatives notify the Company that the Representatives have so arranged for the purchase of such ADSs, or the Company notifies the Representatives that it has so arranged for the purchase of such ADSs or Shares, the Representatives or the Company shall have the right to postpone such Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the Representatives’ opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such ADSs or Shares.

(b) If, after giving effect to any arrangements for the purchase of the ADSs or Shares of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate number of such ADSs or Shares which remains unpurchased does not exceed one-eleventh of the aggregate number of all the ADSs or Shares to be purchased at such Time of Delivery, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of ADSs or Shares which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of ADSs or Shares which such Underwriter agreed to purchase hereunder) of the ADSs or Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the ADSs or Shares of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate number of such ADSs or Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all the ADSs or Shares to be purchased at such Time of Delivery, or if the Company shall not

exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase ADSs of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Second Time of Delivery, the obligations of the Underwriters to purchase and of the Company to sell the Option ADSs or Option Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

11. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the ADSs and the Shares.

12. If this Agreement shall be terminated pursuant to Section 10 hereof, the Company shall not then be under any liability to any Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason, any ADSs or Shares are not delivered by or on behalf of the Company as provided herein or the Underwriters decline to purchase the ADSs or Shares for any reason permitted under this Agreement, the Company will reimburse the Underwriters through the Representatives for all out-of-pocket expenses approved in writing by the Representatives, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the ADSs or Shares not so delivered, but the Company shall then be under no further liability to any Underwriter except as provided in Sections 7 and 9 hereof.

13. In all dealings hereunder, the Representatives shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given on behalf of any Underwriter made or given by the Representatives on behalf of the Underwriters.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to Goldman Sachs Bank Europe SE, Marienturm, Taunusanlage 9-10, 60329 Frankfurt am Main, Germany, Attention: Registration Department; Jefferies LLC, Jefferies International Limited and Jefferies GmbH, 520 Madison Avenue, New York, NY 10022, Attention: General Counsel; and if to the Company shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Secretary; provided, however, that any notice to an Underwriter pursuant to Section 9(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Company by the Representatives upon request; provided, however, that notices under subsection 5(e) shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to Goldman Sachs Bank Europe SE, Marienturm, Taunusanlage 9-10, 60329 Frankfurt am Main, Germany, Attention: Control Room; and Jefferies LLC, Jefferies International Limited and Jefferies GmbH, 520 Madison Avenue, New York, NY 10022. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

In accordance with the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the underwriters to properly identify their respective clients.

14. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the Company and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the ADSs or Shares from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

15. The Representatives and the Underwriters may provide their services through or in conjunction with one or more of their affiliates, and references in this Agreement to the “Representatives” and the “Underwriters” shall, save where the context otherwise requires, include any such affiliates.

16. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

17. The Company acknowledges and agrees that (i) the purchase and sale of the ADSs and the Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Underwriter has 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 such 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) none of the activities of the Underwriters in connection with the transactions contemplated herein constitutes a recommendation, investment advice, or solicitation of any action by the Underwriters with respect to any entity or natural person and (v) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

18. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

19. This Agreement and any transaction contemplated by this Agreement and any claim, controversy or dispute arising under or related thereto shall be governed by and construed in accordance with the laws of the State of New York without regard to principles of conflict of laws that would result in the application of any other law than the laws of the State of New York.

20. The Company hereby submits to the exclusive jurisdiction of the U.S. federal and New York state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. The Company waives any objection which it may now or hereafter have to the laying of venue of any such suit or proceeding in such courts. The Company agrees that final judgment in any such suit, action or proceeding brought in such court shall be conclusive and binding upon the Company and may be enforced in any court to the jurisdiction of which Company is subject by a suit upon such judgment. The Company irrevocably appoints Cogency Global Inc., located at 122 East 42^nd Street, 18^th Floor, New York, New York 10168, as its authorized agent in the Borough of Manhattan in The City of New York upon which process may be served in any such suit or proceeding, and agrees that service of process upon such authorized agent, and written notice of such service to the Company by the person serving the same to the address provided in this Section, shall be deemed in every respect effective service of process upon the Company in any such suit or proceeding. The Company hereby represents and warrants that such authorized agent has accepted such appointment and has agreed to act as such authorized agent for service of process. The Company further agrees to take any and all action as may be necessary to maintain such designation and appointment of such authorized agent in full force and effect.

21. The Company and each of the Underwriters 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.

22. To the extent that the Company has or hereafter may acquire any immunity (sovereign or otherwise) from jurisdiction of any court of (i) France, or any political subdivision thereof, (ii) the United States or the State of New York, (iii) any jurisdiction in which it owns or leases property or assets or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution, set-off or otherwise) with respect to itself or its property and assets, this Agreement or the Deposit Agreement, the Company hereby irrevocably waives such immunity in respect of its obligations under this Agreement and the Deposit Agreement to the fullest extent permitted by applicable law.

23. The Company agrees to indemnify each Underwriter against any loss incurred by such Underwriter as a result of any judgment or order being given or made for any amount due hereunder and such judgment or order being expressed and paid in a currency (the “judgment currency”) other than U.S. dollars and as a result of any variation as between (i) the rate of exchange at which the U.S. dollar amount is converted into the judgment currency for the purpose of such judgment or order, and (ii) the rate of exchange at which such Underwriter is able to purchase U.S. dollars with the amount of the judgment currency actually received by the Underwriter. The foregoing indemnity 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, the relevant currency.

24. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

Notwithstanding anything herein to the contrary, the Company is authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Company relating to that treatment and structure, without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

26. Recognition of the U.S. Special Resolution Regimes.

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

Re: Valneva SE—Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you, as representatives (the “Representatives”), propose to enter into an Underwriting Agreement on behalf of the several Underwriters named in Schedule I to such agreement (collectively, the “Underwriters”), with Valneva SE, a Societates Europaeae incorporated under the laws of France (the “Company”), providing for a public offering of the ordinary shares, par value €0.15 per share, of the Company (the “Ordinary Shares”) in the form of American Depositary Shares (the “ADSs”) pursuant to a Registration Statement on Form F-1 to be filed with the Securities and Exchange Commission (the “SEC”).

In consideration of the agreement by the Underwriters to offer and sell the Ordinary Shares in the form of ADSs (the “Offering”), and of other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning on the date of this Lock-Up Agreement and continuing to and including the date that is 90 days after the date set forth on the cover of the final prospectus (the “Prospectus”) used to sell the ADSs (the “Lock-Up Period”), the undersigned shall not, and shall not cause or direct any of its affiliates to, (i) offer, sell, contract to sell, pledge, grant any option to purchase, lend or otherwise dispose of any Ordinary Shares or ADSs of the Company, or any options or warrants to purchase any Ordinary Shares or ADSs of the Company, or any securities convertible into, exchangeable for or that represent the right to receive Ordinary Shares or ADSs of the Company (such options, warrants or other securities, collectively, “Derivative Instruments” and, together with the Ordinary Shares and ADSs, “Undersigned’s Securities”), including without limitation any such shares or Derivative Instruments now owned or hereafter acquired by the undersigned, (ii) engage in any hedging or other transaction or arrangement (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof,

forward, swap or any other derivative transaction or instrument, however described or defined) which is designed to or which reasonably could be expected to lead to or result in a sale, loan, pledge or other disposition (whether by the undersigned or someone other than the undersigned), or transfer of any of the economic consequences of ownership, in whole or in part, directly or indirectly, of any Ordinary Shares or ADSs of the Company or Derivative Instruments, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of Ordinary Shares or ADSs or other securities, in cash or otherwise (any such sale, loan, pledge or other disposition, or transfer of economic consequences, a “Transfer”) or (iii) otherwise publicly announce any intention to engage in or cause any action or activity described in clause (i) above or transaction or arrangement described in clause (ii) above. The undersigned represents and warrants that the undersigned is not, and has not caused or directed any of its affiliates to be or become, currently a party to any agreement or arrangement that provides for, is designed to or which reasonably could be expected to lead to or result in any Transfer during the Lock-Up Period. For the avoidance of doubt, the undersigned agrees that the foregoing provisions shall be equally applicable to any issuer-directed or other ADSs the undersigned may purchase in the Offering.

If the undersigned is not a natural person, the undersigned represents and warrants that no single natural person, entity or “group” (within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended), other than a natural person, entity or “group” (as described above) that has executed a Lock-Up Agreement in substantially the same form as this Lock-Up Agreement, beneficially owns, directly or indirectly, 50% or more of the common equity interests, or 50% or more of the voting power, in the undersigned.

Notwithstanding the foregoing, the undersigned may transfer or otherwise dispose of the undersigned’s Ordinary Shares or ADSs of the Company (and the foregoing restrictions shall not apply to such transfers or dispositions):

(i)	as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein,

(ii)

to any member of the immediate family of the undersigned or any trust or other legal entity for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the transferee agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value,

(iii)

by will or intestacy, provided that the transferee agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value,

(iv)

to the extent required in order to satisfy the exercise price and/or any income, employment tax withholding and remittance obligations upon the vesting or exercise of an option or other stock award (including free shares) granted under a stock incentive plan, free share plan or similar plan of the Company described in the Prospectus or received upon the conversion or exercise of any securities of the Company described in the Prospectus,

(v)	with the prior written consent of the Representatives on behalf of the Underwriters,

(vi)	acquired in the Offering, or in open market transactions following the Offering,

(vii)

as part of a distribution, transfer or disposition without consideration by the undersigned to its limited or general partners, members, stockholders or affiliates (as defined under Rule 12b-2 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), provided that the transferee agrees to be bound in writing by the restrictions set forth herein and provided further that there shall be no further transfer of such Ordinary Shares or ADSs except in accordance with this Lock-Up Agreement, and provided further that any such transfer shall not involve a disposition for value,

(viii)

in connection with the conversion or exercise of any Derivative Instruments into Ordinary Shares or ADSs, provided that such securities are described in the Prospectus and any such Ordinary Shares or ADSs received upon conversion or exercise shall be subject to the terms of this Lock-Up Agreement,

(ix)

to the Company pursuant to any contractual arrangement in effect on the date of this Lock-Up Agreement and described in the Prospectus that provides for the repurchase of the Undersigned’s Securities by the Company in connection with the termination of the undersigned’s employment or other service relationship with the Company or the undersigned’s failure to meet certain conditions set out upon receipt of such Ordinary Shares or ADSs,

(x)

pursuant to a merger, consolidation, or other similar transaction approved by the Company’s board of directors and made with or offered to all holders of the Company’s Ordinary Shares or ADSs resulting in a change in the ownership of 90% of the voting capital stock of the Company that is made or offered after the Offering (a “Change of Control”), provided that, in the event that such Change of Control is not completed, the Undersigned’s Securities shall remain subject to the restrictions contained in this Lock-Up Agreement and title to the Undersigned’s Securities shall remain with the undersigned, and

(xi)	by operation of law, including pursuant to a domestic order or negotiated divorce settlement, provided that the transferee agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value.

In addition, with respect to clauses (i), (ii), (iii), (v), (vi), (viii), (ix) and (xi) above, it shall be a condition to such transfer that no filing under the Exchange Act or Article L. 621-18-2 of the French Monetary and Financial Code (Code monétaire et financier) and Article 223-23 of the General Regulation of the French Market Authority (Autorité des Marchés Financiers, or “AMF”) or any other public filing or disclosure of such transfer by or on behalf of the undersigned reporting a reduction in beneficial ownership of the Undersigned’s Securities shall be required or voluntarily made during the Lock-Up Period (other than a required filing on Schedule 13G, Schedule 13G/A or Form 13F). With respect to clause (iv) above, any filing under the Exchange Act or applicable provisions of the

General Regulation of the AMF, if required to be made, shall clearly indicate in the footnotes thereto that the filing relates to satisfying the exercise price and/or income, employment tax withholding and remittance obligations upon the vesting or exercise of an option or other stock award. With respect to clause (viii) above, any filing under the Exchange Act or applicable provisions of the General Regulation of the AMF, if required to be made, shall clearly indicate in the footnotes thereto that the filing relates to the conversion of a convertible security into, or the exercise of any option or warrant for, the Ordinary Shares or ADSs, that no Ordinary Shares or ADSs were sold by the reporting person and that the Ordinary Shares or ADSs received upon such conversion or exercise are subject to a lock-up agreement. With respect to clause (ix) above, any filing under the Exchange Act or applicable provisions of the General Regulation of the AMF relating to such disposition shall clearly indicate in the footnotes thereto that the shares were repurchased or reacquired by the Company pursuant to such repurchase right.

For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage, domestic partnership or adoption, not more remote than first cousin. The undersigned now has, and, except as contemplated by clauses (i) through (xi) above, for the duration of this Lock-Up Agreement will have, good and marketable title to the undersigned’s Ordinary Shares and ADSs of the Company, free and clear of all liens, encumbrances, and claims whatsoever. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s Ordinary Shares and ADSs of the Company except in compliance with the foregoing restrictions.

In addition, the undersigned may enter into any plan designed to satisfy the requirements of Rule 10b5-1 (a “10b5-1 Plan”) under the Exchange Act (other than the entry into such a plan in such a manner as to allow the sale of shares of Ordinary Shares or ADSs, in each case, within the Lock-Up Period); provided, however that, no sale of shares of Ordinary Shares or ADSs may be made under such 10b5-1 Plan during the Lock-Up Period; provided further that to the extent a public announcement or filing under the Exchange Act or applicable provisions of the General Regulation of the AMF, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the establishment of such plan, such announcement or filing shall clearly indicate in the footnotes thereto that no transfer of Ordinary Shares or ADSs may be made under such plan during the Lock-Up Period.

The undersigned acknowledges and agrees that none of the Underwriters has made any recommendation or provided any investment or other advice to the undersigned with respect to this Lock-Up Agreement or the subject matter hereof, and the undersigned has consulted its own legal, accounting, financial, regulatory, tax and other advisors with respect to this Lock-Up Agreement and the subject matter hereof to the extent the undersigned has deemed appropriate.

The undersigned understands that the Company and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward consummation of the Offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns.

This Lock-Up Agreement (and for the avoidance of doubt, the Lock-Up Period described herein) and the related restrictions shall automatically terminate and become null and void upon the earliest to occur, if any, of (i) prior to the execution of the Underwriting Agreement, the Representatives, on behalf of the Underwriters, on the one hand, or the Company, on the other hand, advising the other in writing that they have or it has determined not to proceed with the Offering, (ii) the registration statement with respect to the Offering is withdrawn, (iii) the termination of the Underwriting Agreement (other than the provisions thereof which survive termination) prior to the payment for and delivery of the Ordinary Shares or ADSs to be sold thereunder and (iv) December 31, 2021, in the event the initial closing of the Ordinary Shares or ADSs to be sold under the Underwriting Agreement has not occurred prior to such date.

This agreement shall be governed by and construed in accordance with the laws of the State of New York.
