ABOUT THIS PROSPECTUS

This prospectus is a part of a registration statement on Form F-3 that we filed with the U.S. Securities and Exchange Commission (the “SEC”) utilizing a “shelf” registration process. Under this shelf registration process, certain selling securityholders may from time to time sell our ordinary shares, ordinary shares in the form of ADSs or any combination thereof described in this prospectus in one or more offerings or otherwise as described under “Plan of Distribution.” This prospectus only provides you with a general description of the securities we may offer.

For investors outside the United States: Neither we nor the selling securityholders have done anything that would permit this offering or possession or distribution of this prospectus in any jurisdiction where action for that purpose is required, other than in the United States. Persons outside the United States who come into possession of this prospectus must inform themselves about, and observe any restrictions relating to, the offering of the common shares and the distribution of this prospectus outside the United States.

This prospectus may be supplemented from time to time by one or more prospectus supplements. Such prospectus supplements may also add, update or change information contained in this prospectus. If there is any inconsistency between the information in this prospectus and the applicable prospectus supplement, you must rely on the information in the prospectus supplement. You should carefully read both this prospectus and any applicable prospectus supplement together with additional information described under the heading “Where You Can Find More Information” before deciding to invest in any shares being offered.

You should rely only on the information contained in or incorporated by reference in this prospectus and in any free writing prospectus that we authorized for use in connection with this offering. We have not, and the sales agent has not, authorized anyone to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We are not, and the sales agent is not, making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus, the documents incorporated by reference in this prospectus and in any free writing prospectus that we have authorized for use in connection with this offering, is accurate only as of the date of those respective documents. Our business, financial condition, results of operations and prospects may have changed since those dates. You should read this prospectus, the documents incorporated by reference in this prospectus and any free writing prospectus that we have authorized for use in connection with this offering in their entirety before making an investment decision.

We further note that the representations, warranties and covenants made by us in any agreement that is filed as an exhibit to any document that is incorporated by reference in this prospectus were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties to such agreements, and should not be deemed to be a representation, warranty or covenant to you. Moreover, such representations, warranties or covenants were accurate only as of the date when made. Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.

We were incorporated under the laws of France. Under the rules of the SEC, we are currently eligible for treatment as a “foreign private issuer.” As a foreign private issuer, we will not be required to file periodic reports and financial statements with the SEC as frequently or as promptly as domestic registrants whose securities are registered under the Securities Exchange Act of 1934, as amended, or the Exchange Act.

Unless otherwise indicated, all references in this prospectus to, “Valneva,” “the company,” “our company,” “we,” “us” and “our” refer to Valneva SE and its consolidated subsidiaries.

PROSPECTUS SUMMARY

The following summary highlights certain information about us, this offering and selected information contained elsewhere in or incorporated by reference into this prospectus, and does not contain all of the information that you need to consider in making your investment decision. For a more complete understanding of our business and this offering, you should carefully read the entire prospectus and the documents incorporated by reference herein, including our consolidated financial statements and the notes thereto, which are incorporated herein by reference. Investing in our securities involves risks. Therefore, carefully consider the risk factors set forth in this prospectus and in our most recent filings with the SEC including our Annual Reports on Form 20-F and reports on Form 6-K, as well as other information in this prospectus s and the documents incorporated by reference herein or therein, before purchasing our securities. Each of the risk factors could adversely affect our business, operating results and financial condition, as well as adversely affect the value of an investment in our securities.

Company Overview

Please see the section entitled “Information on the Company – Business Overview,” incorporated by reference from our Annual Report on Form 20-F for the fiscal year ended December 31, 2025, filed with the SEC on March 17, 2026, as well as any amendments thereto reflected in our subsequent filings with the SEC.

Private Placement

Securities Purchase Agreement

On April 29, 2026, we entered into a securities purchase agreement (the “Securities Purchase Agreement”) with the investors named therein (each an “Investor,” and together, the “Investors”), pursuant to which we agreed to issue and sell to the Investors in a private placement (the “Private Placement”) 15,893,817 new Ordinary Shares, nominal value €0.15 per share (the “New Shares”), each New Share with a warrant attached (a “Warrant” and, together with the New Share to which it is attached, an “ABSA”, or Actions à Bons de Souscription d’Actions) exercisable for one Ordinary Share at a subscription price of €2.33 per ABSA. On May 5, 2026, we closed the Private Placement and issued an aggregate of 31,787,634 Ordinary Shares, nominal value €0.15 per share (the “Resale Shares”), consisting of (i) up to 15,893,817 issued and outstanding Ordinary Shares, and (ii) up to 15,893,817 Ordinary Shares (the “ABSA Warrant Shares”) issuable upon the exercise of warrants to purchase ordinary shares (the “ABSA Warrants”).

Each Warrant entitles its holder to subscribe to one Warrant Share at an exercise price of €2.96 per Warrant Share, representing a premium of 25% to the volume-weighted average price of the Ordinary Shares on the regulated market of Euronext Paris over the three trading days preceding the setting of such issue price, i.e. April 27, 28 and 29, 2026 (i.e. €2.37), subject to standard adjustments. The Warrants may be exercised, in whole or in part, for cash, at any time from the business day immediately following their issuance to the earlier of (i) the 30th calendar day following receipt by us of the FDA regulatory approval for its investigational 6-valent OspA-based Lyme disease vaccine candidate (LB6V, formerly known as VLA15) (the “FDA Approval”) and (ii) the third business day (included) prior to March 31, 2028 (the “Maturity Date” and such period, the “Exercise Period”). If, as of March 1, 2028, the FDA Approval has not been obtained by the us, the Maturity Date shall automatically be extended to September 30, 2028 and the Exercise Period shall be correspondingly extended.

The Warrants provide that the holder will not have the right to exercise any portion of its Warrants if such holder, together with its affiliates, would beneficially own in excess of 9.99% of the number of Ordinary Shares outstanding immediately after giving effect to such exercise (the “Beneficial Ownership Limitation”). The holder may increase or decrease the Beneficial Ownership Limitation, provided that (i) to the extent required by the French foreign direct investment regime (“French FDI Regime”), the holder may only increase the Beneficial Ownership Limitation above 9.99% if the holder has obtained from the French Ministry of Economy through an authorization request or prior notification, in accordance with the French FDI Regime and (ii) in no event will the Beneficial Ownership Limitation exceed 19.99%. Any increase in the Beneficial Ownership Limitation will not be effective until the 61^st day after such notice is delivered to us.

Registration Rights Agreement

On April 29, 2026, in connection with the Private Placement, we entered into a registration rights agreement (the “Registration Rights Agreement”) with the Investors, pursuant to which we agreed to register the New Shares and Warrant Shares for resale (together, the “Registrable Securities”). Under the Registration Rights Agreement, we have agreed to file this registration statement covering the resale of the Registrable Securities by no later than 30 days after the Closing Date (the “Filing Deadline”) and to use reasonable best efforts to cause such registration statement to be declared effective as soon as practicable, but no later than the earlier of (a) the 60^th calendar day following the initial filing date of the registration statement if the U.S. Securities and Exchange Commission (the “SEC”) notifies us that it will “review” the registration statement and (b) the 10^th business day after the date we are notified (orally or in writing, whichever is earlier) by the SEC that the initial registration statement will not be “reviewed” or will not be subject to further review(the “Effectiveness Deadline”). We also agreed to use reasonable efforts to keep such registration statement continuously effective until the date the Registrable Securities covered by such registration statement have been sold or may be resold pursuant to Rule 144 without restriction. We have agreed to be responsible for all reasonable fees and expenses incurred in connection with the registration of the Registrable Securities.

Corporate Information

Please see the section entitled “Information on the Company – History and development of the company,” incorporated by reference from our Annual Report on Form 20-F for the fiscal year ended December 31, 2025, filed with the SEC on March 17, 2026, as well as any amendments thereto reflected in our subsequent filings with the SEC.

The information contained on our website is not incorporated by reference into this prospectus, and you should not consider any information contained on, or that can be accessed through, our website as part of this prospectus or in deciding whether to purchase our securities.

Implications of Being a Foreign Private Issuer

We are considered a “foreign private issuer” under U.S. securities laws. In our capacity as a foreign private issuer, we are exempt from certain rules under the U.S. Securities Exchange Act of 1934, as amended, or the Exchange Act, that impose certain disclosure obligations and procedural requirements for proxy solicitations under Section 14 of the Exchange Act. In addition, members of our Executive Committee and Board of Directors and our principal securityholders are exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act and the rules under the Exchange Act with respect to their purchases and sales of our securities. Moreover, we are not required to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act. In addition, we are not required to comply with Regulation FD, which restricts the selective disclosure of material information.

We may take advantage of these exemptions until such time as we are no longer a foreign private issuer. We will remain a foreign private issuer until such time that more than 50% of our outstanding voting securities are held by U.S. residents and any of the following three circumstances applies: (1) the majority of our executive officers or directors are U.S. citizens or residents; (2) more than 50% of our assets are located in the United States; or (3) our business is administered principally in the United States.

Use of proceeds	We will not receive any proceeds from the sale of the Resale Shares by the selling securityholders, except with respect to amounts received by us due to the exercise of any ABSA Warrants for cash.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully review the risks and uncertainties described below and under the heading “Risk Factors” in our Annual Report on Form 20-F for the year ended December 31, 2025 as updated by our subsequent filings including our Reports on Form 6-K, which are incorporated by reference into this prospectus, before deciding whether to purchase any of the securities being registered pursuant to the registration statement of which this prospectus is a part. The risk factors included in our Annual Report include a discussion of specific risks related to an investment in, and ownership of, ADSs under the caption “- Risks related to Ownership of Our Ordinary Shares and ADSs.” Each of the risk factors could adversely affect our business, results of operations, financial condition and cash flows, as well as adversely affect the value of an investment in our securities, and the occurrence of any of these risks might cause you to lose all or part of your investment. Additional risks not presently known to us or that we currently believe are immaterial may also significantly impair our business operations. Please also read carefully the section below titled “Special Note Regarding Forward-Looking Statements.”

A substantial number of our securities may be sold in the market following the effective date of the registration statement of which this prospectus forms a part, which may depress the market price for our ADSs.

USE OF PROCEEDS

We will not receive any of the proceeds from the sale of Resale Shares in this offering, except with respect to amounts received by us due to the exercise of any ABSA Warrants for cash. We could potentially receive up to €47 million in proceeds from the exercise of the ABSA Warrants, as described herein, assuming the exercise in full of all of such ABSA Warrants for cash. There is no assurance that the holders of the ABSA Warrants will elect to exercise any or all of such ABSA Warrants. The selling securityholders will receive all of the proceeds from the sale of Resale Shares hereunder.

We currently intend to use the net proceeds from the exercise of any ABSA Warrants for cash, if any, to fund manufacturing, commercialization, and research and development of our products and product candidates, for working capital and for general corporate purposes.

PLAN OF DISTRIBUTION

The selling securityholders of the Resale Shares and any of their donees, pledgees, transferees or other successors-in-interest selling the Resale Shares received after the date of this prospectus from a selling securityholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their Resale Shares covered hereby on any stock exchange, market or trading facility on which the Resale Shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market prices, at varying prices determined at the time of sale, or at negotiated prices.

The selling securityholders may use any one or more of the following methods when disposing of their securities or interests therein:

●

distributions to members, partners, stockholders or other securityholders of the selling securityholders;

●

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

●

block trades in which the broker-dealer will attempt to sell the ordinary shares or ADSs as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

●

purchases by a broker-dealer as principal and resale by the broker-dealer for its accounts;

●

an exchange distribution in accordance with the rules of the applicable exchange;

●

privately negotiated transactions;

●

short sales and settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part;

●

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

●

broker dealers who may agree with the selling securityholders to sell a specified number of such securities at a stipulated price per ordinary share or ADSs;

●

a combination of any such methods of sale; and

●

any other method permitted pursuant to applicable law.

The selling securityholders may, from time to time, pledge or grant a security interest in some or all of the Resale Securities owned by them and, if a selling securityholder defaults in the performance of its secured obligations, the pledgees or secured parties may offer and sell the Resale Securities, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Ace, amending the list of the selling securityholders under this prospectus. The selling securityholders also may transfer the Resale Securities in other circumstances, in which case the transferees, pledgees, or other successors in interest will be the selling securityholders for purposes of this prospectus.

In connection with the sale of the Resale Securities or interests therein, the selling securityholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the Resale Securities in the course of hedging the positions they assume. The selling securityholders may also sell the Resale Securities short and deliver these securities to close out their short positions, or loan or pledge the Resale Securities to broker-dealers that in turn may sell these securities. The selling securityholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities that require the delivery to such broker-dealer or other financial institution or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to the selling securityholders from the sale of Resale Securities offered by them will be the purchase price of the Resale Securities, less discounts or commissions, if any. Each of the selling securityholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of Resale Securities to be made directly or through agents. We will not receive any of the proceeds from any offering by the selling securityholders. Upon any exercise of the Warrants by payment of cash, however, we will receive the exercise price of the Warrants.

The selling securityholders also may resell a portion of the Resale Securities in open-market transactions in reliance upon Rule 144 under the Securities Act, provided that they meet the criteria and conform to the requirements of that rule, or another available exemption from the registration requirement sunder the Securities Act.

The selling securityholders and any underwriters, broker-dealers or agents that participate in sale of the Resale Securities or interests therein may be “underwriters” within the meaning of Section 2(a)(11) of the Securities Act (it being understood that the selling securityholders shall not be deemed to be underwriters solely as a result of their participation in this offering). Any discounts, commissions, concessions, or profit they earn on any resale of the Resale Securities may be underwriting discounts and commissions under the Securities Act. Selling securityholders who are “underwriters” within the meaning of Section 2(a)(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.

To the extent required, the number of Resale Securities to be sold, the names of the selling securityholders, the respective purchase prices and public offering prices, the names of any agent, dealer, or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the Resale Securities may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the Resale Securities may not be sold unless such securities have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

We have advised the selling securityholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of Resale Securities in the market and to the activities of the selling securityholders and their affiliates. In addition, to the extent applicable, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling securityholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling securityholders may indemnify any broker-dealer that participates in transactions involving the sale of the Resale Securities against certain liabilities, including liabilities arising under the Securities Act

We have agreed to indemnify the selling securityholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the Resale Securities offered by this prospectus.

We have agreed with the selling securityholders to use commercially reasonable efforts to cause the registration statement of which this prospectus constitutes a part to become effective and to remain continuously effective until the earlier of: (i) the date on which the selling securityholders shall have resold or otherwise disposed of all the Resale Securities covered by this prospectus and (ii) the date on which the Resale Securities covered by this prospectus no longer constitute “Registrable Securities” as such term is defined in the Registration Rights Agreement, such that they may be resold by the selling securityholders without registration and without regard to any volume or manner-of-sale limitations and without current public information pursuant to Rule 144 under the Securities Act or any other rule of similar effect.

selling securityholders

We have prepared this prospectus to allow the selling securityholders to offer and sell from time to time for their own account up to 31,787,634 Resale Shares, which may be in the form of ADSs, consisting of (i) up to 15,893,817 issued and outstanding ordinary shares and (ii) up to 15,893,817 ABSA Warrant Shares issuable upon the exercise of the ABSA Warrants.

We are registering the offer and sale of the Resale Shares beneficially owned by the selling securityholders to satisfy our obligations to them pursuant to a registration rights agreement dated April 29, 2026 (the “Registration Rights Agreement”) by and among the Company and the selling securityholders. Pursuant to the Registration Rights Agreement, we have agreed to prepare and file a registration statement with the SEC within 30 days following the Closing Date (as defined in the Securities Purchase Agreement). We have also agreed to use our reasonable best efforts to keep the registration statement continuously effective pursuant to Rule 415 and available for the resale by the selling securityholders until the earlier to occur of: (i) the date on which the selling securityholders have resold all of the Registrable Securities (as defined in the Registration Rights Agreement) , and (ii) the date on which all of the Registrable Securities may be resold by the selling securityholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information requirement under Rule 144.

To our knowledge, none of the selling securityholders has, or during the three years prior to the date of this prospectus has had, any position, office or other material relationships with us or any of our affiliates, except that we and each selling securityholders are party to the Registration Rights Agreement relating to the Resale Shares described above. To our knowledge, based on information provided to us, none of the selling securityholders that are affiliates of broker-dealers purchased the Resale Shares outside the ordinary course of business, nor at the time of the acquisition did any selling securityholder have direct or indirect agreements or understandings with any person to distribute any ordinary shares, including the Resale Shares.

The information set forth in the table below is based upon information obtained from the selling securityholders. Beneficial ownership of the selling securityholders is determined in accordance with Rule 13d-3(d) under the Exchange Act. The percentage of shares beneficially owned prior to the offering is based on 189,771,237 ordinary shares outstanding as of May 31, 2026, after giving effect to the issuance of 15,893,817 ordinary shares issued on May 5, 2026 pursuant to the Securities Purchase Agreement, but excluding 15,893,817 ABSA Warrant Shares. The percentage of shares beneficially owned after the offering assumes the sale of all Resale Shares offered by the selling securityholders, including all ABSA Warrant Shares, pursuant to this prospectus and no further acquisitions of our securities by the selling securityholders. In computing the number of ordinary shares beneficially owned by a selling securityholder and the percentage ownership of such selling securityholder, we deemed outstanding ordinary shares issuable upon exercise of the ABSA Warrants, as applicable, held by that selling securityholder that are exercisable within 60 days of May 31, 2026. We did not deem these ordinary shares outstanding, however, for the purpose of computing the percentage ownership of any other selling securityholder.

The number of ordinary shares set forth in the following table for any selling shareholder reflects the exercise limitations as set forth in the ABSA Warrants. The ABSA Warrants provide that the holder of ABSA Warrants will not have the right to exercise any portion of its ABSA Warrants if such holder, together with its affiliates, would beneficially own in excess of 9.99% of the number of ordinary shares outstanding immediately after giving effect to such exercise (the “Beneficial Ownership Limitation”). The holder may increase or decrease the Beneficial Ownership Limitation, provided, however, that the holder may only increase the Beneficial Ownership Limitation (i) by obtaining authorization from the French Ministry of Economy in the event the Beneficial Ownership Limitation is being raised above 9.99%, (ii) by providing 61 days’ notice to the Company, except that in no event will the Beneficial Ownership Limitation exceed (i) with respect to the limitations under Section 13(d) of the Exchange Act, 19.99% of our ordinary shares and (ii) with respect to the French regime for control of foreign direct investments, 24.99% of the voting rights. Accordingly, the number of ordinary shares set forth in the following table for any shareholder may exceed the number of ordinary shares that it could own beneficially at any given time as a result of its ownership of ABSA Warrant Shares. As a result, the actual number of ABSA Warrant Shares that may be issued to and sold by the selling securityholders could be materially less than the estimated numbers in the column titled “Number of Shares Being Offered” depending on factors which cannot be predicted by us at this time. In addition, we do not know how long the selling securityholders will hold the Resale Shares before selling them, and we currently have no agreements, arrangements or understandings with the selling securityholders regarding the sale or other disposition of any Resale Shares.

As used in this prospectus, the term “selling securityholders” includes the selling securityholders listed in the table below, together with any additional selling securityholders listed in a prospectus supplement, and their donees, pledgees, assignees, transferees, distributees and successors-in-interest that receive Resale Shares in any non-sale transfer after the date of this prospectus. Unless otherwise indicated, the address for each selling securityholder is c/o Valneva SE, Îlot Saint Joseph Bureaux Convergence, 12T Quai Perrache, 69002 Lyon, France.

SERVICE OF PROCESS AND ENFORCEMENT OF LIABILITIES

We are a corporation organized under the laws of France. The majority of the members of our Executive Committee and Board of Directors are citizens and residents of countries other than the United States, and the majority of our assets are located outside of the United States. We have appointed an agent for service of process in the United States; however, it may be difficult for investors:

●

to obtain jurisdiction over us or our non-U.S. resident members of the Executive Committee and Board of Directors in U.S. courts in actions predicated on the civil liability provisions of the U.S. federal securities laws;

●

to enforce judgments obtained in such actions against us or our non-U.S. resident members of the Executive Committee and Board of Directors;

●

to bring an original action in a French court to enforce liabilities based upon the U.S. federal securities laws against us or our non-U.S. resident members of the Executive Committee and Board of Directors; and

●

enforce against us or our Executive Committee in non-U.S. courts, including French courts, judgments of U.S. courts predicated upon the civil liability provisions of the U.S. federal securities laws.

Nevertheless, a final judgment for the payment of money rendered by any federal or state court in the United States based on civil liability, whether or not predicated solely upon the U.S. federal securities laws, would be recognized and enforced in France provided that a French judge considers that this judgment meets the French legal requirements concerning the recognition and the enforcement of foreign judgments and is capable of being immediately enforced in the United States. A French court is therefore likely to grant the enforcement of a foreign judgment without a review of the merits of the underlying claim, only if (1) that judgment was rendered by a court having jurisdiction over the dispute (the condition will be met if the dispute is clearly connected to the jurisdiction of the U.S. court and French courts did not have exclusive jurisdiction over the matter), (2) that judgment does not contravene French international public order and public policy, including the right to due process, (3) the U.S. judgment is not tainted with fraud and (4) is not incompatible with a judgment rendered by a French court in the same matter, or with an earlier judgment rendered by a foreign court in the same matter.

In addition, French law guarantees full compensation for the harm suffered but is limited to the actual damages, so that the victim does not suffer or benefit from the situation. Such system excludes damages such as, but not limited to, punitive and exemplary damages.

As a result, the enforcement, by U.S. investors, of any judgments obtained in U.S. courts in civil and commercial matters, including judgments under the U.S. federal securities law against us or members of our Executive Committee and Board of Directors or certain experts named herein who are residents of France or countries other than the United States would be subject to the above conditions.

Finally, there may be doubt as to whether a French court would impose civil liability on us, the members of our Executive Committee and Board of Directors or certain experts named herein in an original action predicated solely upon the U.S. federal securities laws brought in a court of competent jurisdiction in France against us or such members, officers or experts, respectively.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 8. Indemnification of Directors and Officers.

Under French law, provisions of bylaws that limit the liability of directors are prohibited. However, French law allows a Société Européenne to contract for and maintain liability insurance against civil liabilities incurred by any of their directors and officers involved in a third-party action, provided that they acted in good faith and within their capacities as directors or officers of the company. Criminal liability cannot be indemnified under French law, whether directly by the company or through liability insurance.

We maintain liability insurance for the members of our Board of Directors, Chief Executive Officer and Associate Managing Officers, including insurance against liability under the Securities Act of 1933, as amended, and we have entered into agreements with the members of our Board of Directors, Chief Executive Officer and Associate Managing Officers to provide contractual indemnification. With certain exceptions and subject to limitations on indemnification under French law, these agreements will provide for indemnification for damages and expenses including, among other things, attorneys’ fees, judgments, fines and settlement amounts incurred by any of these individuals in any action or proceeding arising out of his or her actions in that capacity.

Item 10. Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (the “Securities Act”);

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii), and (a)(1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is a part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Securities Act of 1933 need not be furnished, provided, that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (a)(4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, with respect to registration statements on Form F-3, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act of 1933, or Item 8.A of Form 20-F if such financial statements and information are contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Form F-3.

II-2

(5) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(6) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(7) That, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s Annual Report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s Annual Report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-3

(b) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

II-4
