The Company will notify the Holders of the beginning of the Exercise Period pursuant to Condition 12.

For the avoidance of doubt the Holder may exercise all or parts of its Warrants in one or several times within the Exercise Period, it being specified that each Warrant shall be exercised only once. No ink-original Exercise Notice shall be required, nor shall any type of guarantee or notarization of any Exercise Notice be required. The Aggregate Exercise Price shall be paid at the latest on the Exercised Shares Delivery Date (as defined below).

(d) Confirmation of Exercise

Upon receipt by the Registrar of an Exercise Notice and the corresponding Aggregate Exercise Price in accordance with Condition 2(c), the Registrar shall as soon as practicable, but in no event later than 5:00 p.m. Paris time, on the second Business Day immediately following the Exercise Date, send, by facsimile transmission or by email, with a copy to the Company, a confirmation of receipt of such Aggregate Exercise Price and Exercise Notice in the form of the notice at Appendix B to the Holder.

(e) Issue of Warrant Shares Upon Exercise

In the event of any exercise of the rights represented by the Warrants in accordance with Condition 2(c), the Company shall allot and issue to the Holder the Warrant Shares to which the Holder thereby becomes entitled on or with effect from the Exercise Date. In such event the Company shall cause the Registrar to, on or before the third Business Day (the “Exercised Shares Delivery Date”) following the Exercise Date, credit such aggregate number of Warrant Shares to which the Holder shall be entitled to and as notified in the Exercise Notice (i) to the Holder’s securities account opened in the name of the Holder with the Registrar, or (ii) to the Holder’s securities account opened in the name of the Holder with any other financial intermediary and indicated in the Exercise Notice, or (iii) in the name of the Holder, to The Bank of New York Mellon (or any successor thereto) as the depositary for the Company’s American Depositary Shares.

The Company shall pay all applicable fees and expenses of the depositary for the Company’s American Depositary Shares in connection with the issuance of the Warrant Shares in the form of American Depositary Shares or the conversion of Warrant Shares in the form of Shares into American Depositary Shares.

(f) Holder’s Exercise Limitations.

Neither the Company nor the Registrar shall effect any exercise of the Warrants, and the Holder shall not have the right to exercise any portion of the Warrants, pursuant to Condition 2 or otherwise, to the extent that after giving effect to such issuance after exercise as set forth on the applicable Exercise Notice, the Holder (together with the

4

Holder’s Affiliates and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates (such Persons, collectively, the “Attribution Parties”)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of Shares beneficially owned by the Holder and its Affiliates and Attribution Parties shall include the number of Shares held by the Holder and its Attribution Parties plus the number of Warrant Shares with respect to which such determination is being made, but shall exclude the number of Shares which would be issuable upon (i) exercise of the remaining, unexercised portion of Warrant Shares beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other Share Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein that are beneficially owned by the Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Condition 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Condition 2(f) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Exercise Notice shall be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of the Warant Shares is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Condition 2(f), in determining the number of outstanding Shares, the Holder may rely on the number of outstanding Shares as reflected in (x) the Company’s most recent Annual Report on Form 20-F, Report on Form 6-K or other public filing with the Commission, as the case may be, (y) a more recent public announcement by the Company or (z) any other written notice by the Company setting forth the number of Shares outstanding. Upon the written or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing or by electronic mail to the Holder the number of Shares then outstanding. In any case, the number of outstanding Shares shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding Shares was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of Shares outstanding immediately after giving effect to the issuance of Shares issuable upon exercise of this Warrant. The Holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Condition 2(f), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of Shares outstanding immediately after giving effect to the issuance of Shares upon exercise of this Warrant held by the

5

Holder and the provisions of this Condition 2(f) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until the sixty first (61^st) day after such notice is delivered to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Condition 2(f) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant.

3. Warrant Shares

(a) Form of Warrant Shares

The Warrant Shares will be, upon issuance by the Registrar and at the option of the Holder, (i) held in registered form (au nominatif) (including administered registered form (nominatif administré)) in the securities account opened in the name of the Holder in the books of the Registrar (and, if held in administered registered form, of the Holder’s financial intermediary), or (ii) in bearer form (au porteur), in the securities account opened in the name of the Holder in the books of the Holder’s financial intermediary.

The Warrant Shares may, at the request of the Holder and as indicated in the Exercise Notice, be deposited with The Bank of New York Mellon (or any successor thereto) as the depositary for the Company’s American Depositary Shares.

(b) Dividend Due Date and Rights Attached to the Warrant Shares

Upon issue, Warrant Shares allotted pursuant to an Exercise Notice will grant the same rights, including, as from their date of issuance, the right to any dividend or any other distribution decided or to be paid, as are granted to holders of the Shares, and will be entirely assimilated to the Shares.

Warrant Shares shall be subject to all the Company’s by-laws’ provisions and to the decisions of the shareholders’ meetings.

Once issued, application will be made, on date of issuance, by the Registrar on behalf of the Company for the Warrant Shares to be admitted to trading on Euronext, on the same quotation line as the Shares.

(c) Transfer of Warrant Shares

Warrant Shares will, upon issuance, be freely negotiable and transferable as from the date of their entry in a securities account.

In accordance with the provisions of Articles L. 211-15 and L. 211-17 of the French Monetary and Financial Code, Shares are transferred from account to account and transfer of ownership of the Warrant Shares will result from the moment they are registered in the name of the transferee or by book entry, as applicable.

Application will be made for all the Warrant Shares to be admitted to Euroclear France.

6

4. Fractional Interests

No fractional Shares shall be issuable upon the exercise of a Warrant.

Any adjustment will be made so that it equalizes, up to the next 1/100th of a Share, the value of Warrant Shares that would have been obtained if Warrants had been exercised immediately before the implementation of one of the Transactions mentioned in Condition 5 and the value of the Warrant Shares that would have been obtained in the event of exercising the Warrants immediately after the implementation of that Transaction.

In case of adjustments made in accordance with paragraphs 1 to 9 mentioned in Condition 5 (or, as the case may be, Condition 9), the new Exercise Ratio will be determined with two decimals rounded to the next 1/100th (0.005 rounded up to the next 1/100th, i.e. 0.01). Possible subsequent adjustments will be effected based on the preceding Exercise Ratio as so calculated and rounded. The Warrant Shares, however, may only be delivered in a whole number of Shares.

If the number of Warrant Shares thus calculated is not a whole number, the Holder may request delivery of either:

(a) the next lower number of Warrant Shares; in which case the Holder will receive from the Company a cash payment equal to the product of the remaining fractional share multiplied by the value of a Share, equal to the last price quoted on Euronext Paris on the last trading day preceding the Exercise Date;

(b) the next greater number of Warrant Shares, provided that in such case the Holder pays to the Company, together with the Aggregate Exercise Price, an amount equal to the value of the additional fraction of a Share thus delivered, calculated on the basis set out in the preceding paragraph. The calculation of such amount made by the Holder shall not be binding on the Company and the Registrar, and the Company or the Registrar will be entitled to disregard the choice of the Holder to apply this paragraph (b), and therefore apply paragraph (a) if either of them disagree with this calculation, in which case they will refund the Holder of the amount in question.

If the Holder does not state a choice, it will receive a number of Shares rounded down to the nearest whole number, and the remainder in cash as described above.

5. Adjustments of Exercise Ratio and Exercise Price

Warrants issued by the Company are securities giving access to the share capital of the Company within the meaning of Article L. 228-91 et seq. of the French Commercial Code.

The Exercise Price and/or the number of Warrant Shares will be subject to adjustment from time to time according to mandatory legal requirements imposed by the French Commercial Code and in particular by articles L. 228-98 to L. 228-101 (with the exception of the provisions of Articles L. 228-99 1°) and L. 228-99 2°)) and articles R. 228-90 to R. 228-92 of this Code.

In accordance with the provisions of Article R. 228-92 of the French Commercial Code, if the Company decides to issue new Shares or securities giving access to the capital with preferential subscription rights limited to its shareholders, to distribute reserves (in cash or in kind) and share premiums or to change the allocation of its profits by creating preferred Shares, or to otherwise carry out any of the Transactions listed below, it will inform (as long as the current regulation so requires) the Holders via an announcement in the Bulletin des Annonces Légales Obligatoires and pursuant to Condition 12.

7

If the Company is absorbed by a company or merges or consolidates with (fusions) one or several other companies to participate in the incorporation of a new entity, or proceed with a split (scission), the Holders shall exercise their rights in the entity(ies) that is/are the beneficiary(ies) of the contributions in accordance with the provisions of Article L. 228-101 of the French Commercial Code.

So long as any Warrants are outstanding and upon contemplation of the following transactions (each, a “Transaction”):

- financial transactions (issuance of Shares or any other securities of any nature) with listed preferential subscription rights or by free allocation of listed subscription warrants;

- free allocation of Shares to shareholders, regrouping or splitting Shares;

- incorporation of reserves, profits or premiums into equity, by increasing the nominal value of the Shares;

- distribution of reserves and of any Share premium, in cash or in kind;

- free allocation, to the shareholders of the Company of any securities of the Company (except Shares);

- merger by acquisition (fusion par absorption), merger (fusion par création d’une nouvelle société), spin-off, or division (scission) of the Company;

- buyback of its own Shares at a price higher than the stock market price;

- amortization of the share capital; and

- change in the allocation of profits and/or creation of preferred Shares;

which the Company can effect from the Issue Date, and for which the date on which the holding of Shares is established in order to determine the shareholders benefitting from a Transaction, is before the Exercise Date, the maintenance of the rights of the Holders will be ensured by proceeding to an adjustment of the Exercise Ratio in accordance with the conditions below.

1.     (a)   For financial transactions (issuance of Shares or any other securities of any nature) with listed preferential right to subscription, the new Exercise Ratio will equal the product of the Exercise Ratio applicable before the start of the Transaction at issue and the following ratio:

Value of a Share after detachment of the preferential subscription right

+Value of the preferential subscription right

Value of a Share after detachment of the preferential subscription right

To calculate this ratio, the value of a Share after detachment of the preferential subscription right and the value of the preferential subscription right are equal to the average of the opening prices listed on the Trading Market as reported by Bloomberg L.P. during all trading days included in the subscription period during which the Shares and the subscriptions rights are simultaneously listed.

8

(b) For financial transactions carried out through the free allocation of listed subscription warrants to shareholders with a correlative ability to sell the securities resulting from subscription warrants not exercised by their holders during the period of subscription which has opened to them, the new Exercise Ratio will be equal to the product of the Exercise Ratio before the start of the Transaction contemplated and of the following ratio:

Value of a Share after detachment of the subscription warrant

+Value of the subscription warrant

Value of a Share after detachment of the subscription warrant

- the value of a Share after detachment of the subscription warrant will be equal to the VWAP of (i) the prices of the Company’s Shares listed on the Trading Market during all trading days included in the subscription period, and, if there is a rump placement, (ii) either (a) the sale price of the Shares sold in the rump placement, or (b) the VWAP of the Shares on the Trading Market on the day the sale price for the securities sold in the rump placement is fixed, if such securities are not fungible with the Shares;

- the value of the subscription warrant will be equal to the VWAP of (i) the prices of the subscription warrants listed on the Trading Market on each trading day included in the subscription period, and (ii) the implicit value of the subscription warrants, being equal to either (a) the difference, if positive, adjusted by the warrant exercise ratio, between the sale price of the securities sold in the rump placement and the subscription price of the securities upon the exercise of the subscription warrants, or (b) if such difference as aforesaid is not positive, zero (0).

2. In case of a free allocation of Shares to shareholders, and also in case of regrouping or splitting of Shares, the new Exercise Ratio will be equal to the product of the Exercise Ratio applicable before the start of the Transaction contemplated and of the following ratio:

Number of Shares forming the share capital after the Transaction

Number of Shares forming the share capital before the Transaction

3. In case of a capital increase by incorporation of reserves, profits or premiums carried out by increasing the nominal value of the Shares, the nominal value of the Warrant Shares the Holders could obtain by exercising their Warrants will be increased in due proportion.

4. In case of a distribution of reserves and of any share premiums, either in cash or in kind (securities in portfolio...), the new Exercise Ratio will be equal to the product of the Exercise Ratio applicable before the start of the Transaction contemplated and of the following ratio:

Value of a Share before distribution

Value of a Share before distribution

9

- Amount per Share of the distribution or value of securities or assets distributed per Share.

For the calculation of this ratio:

- the value of a Share before the distribution will be equal to the VWAP of the prices of the Shares listed on the Trading Market during the last three trading days preceding the day the Shares are listed ex-distribution;

- if distribution is made in kind:

o in case of delivery of securities already listed on a Trading Market, the value of the securities will be determined as above,

o in case of delivery of securities not yet listed on a Trading Market, the value of securities remitted will be equal, if they should be listed on a Trading Market during the ten trading day period starting from the date on which the Shares are listed ex-distribution, to the VWAP of the Shares listed on such trading Market during the three first trading days included in this period during which the said securities are listed, and

o in all other cases (securities delivered not listed on a Trading Market or listed during less than three trading days within the ten trading day period mentioned above or distribution of assets), the value of the securities or the assets delivered per Share shall be determined by an independent expert of international reputation appointed by the Company.

5. In case of a free allocation to shareholders of securities, other than Shares and subject to paragraph 1 b) above, the new Exercise Ratio will be equal to:

(a) if the rights to the free allocation of securities were listed on the Trading Market, the product of the Exercise Ratio applicable before the start of the Transaction contemplated and of the following ratio:

Share price ex-right to free allocation + value of the right to free allocation

Share price ex-right to free allocation

For the calculation of this ratio:

- the value of the Share price ex-right of free allocation will be equal to the VWAP of the Shares listed on the Trading Market of the Share ex-right of free allocation during the first ten trading days starting on the date on which the Shares are listed ex-right of free allocation;

- the value of the right to free allocation will be determined as in the above paragraph.

If the right to free allocation is not listed during each of the ten trading days, its value will be determined by an independent expert of international reputation appointed by the Company.

10

(b) if the right to free allocation of securities were not listed on the Trading Market, the product of the Exercise Ratio applicable before the start of the Transaction contemplated and of the following ratio:

Share price ex-right to free allocation

+ Value of that/those security(ies) allocated per Share

Share price ex-right to free allocation

For the calculation of this ratio:

- the Share price ex-right to allocation will be determined as in paragraph a) above.

- if these securities are listed or can be listed on the Trading Market within ten trading days starting from the day Shares are listed ex-distribution, the value of the securities allocated by Share will be equal to the VWAP of these securities listed on said market during the three first trading days included in this period during which said securities are listed. If the allocated securities are not listed during each of these three market trading days, the value of these securities will be determined by an independent expert of international reputation appointed by the Company.

6. In case of an absorption of the Company by another company (fusion par absorption) or a merger with one or more companies resulting in the incorporation of a new company(fusion par creation d’une nouvelle societe), a spin-off or division (scission) of the Company, the exercise of the Warrants will allow allocation of shares of the absorbing company or the new company(ies) or the company(ies) resulting from any division or spin-off.

The new Exercise Ratio will be determined by multiplying the Exercise Ratio applicable before the start of the contemplated Transaction by the exchange ratio of the Shares against the shares of the absorbing company or the new company(ies) or the company(ies) resulting from any division or spin-off. These companies will be fully subrogated to the Company’s rights and obligations towards the Holders.

7. In case of a buyback of the Company of its own Shares (except for buyback made pursuant to article L.225-209 al. 2 of the French Commercial Code) at a price higher than the stock exchange price, the new Exercise Ratio will be equal to the product of the Exercise Ratio applicable before the buyback and the following ratio:

Share price x (1-Pc%)

Share price – Pc% x Buyback price

For the calculation of this ratio:

- Share price means the VWAP of the Shares listed on the Trading Market during the three last trading days preceding the buyback (or the ability of buyback):

- Pc% means the percentage of total share capital repurchased; and

- Buyback price means the effective buyback price.

11

8. In case of amortization of the share capital of the Company, the new Exercise Ratio will be equal to the product of the Exercise Ratio on the date before the start of the contemplated Transaction and of the following ratio:

Value of a Share before amortization

Value of a Share before amortization - amount of the amortization per Share

For the calculation of the ratio, the Share value before amortization will be equal to the VWAP of the Shares listed on the Trading Market during the three last trading days preceding the trading day the Shares are listed ex- amortization.

9.     (a)   In case of a change in the allocation of profits and/or creation of new preferredshares resulting in such modification by the Company, the new Exercise Ratio will be equal to the product of the Exercise Ratio before the start of the contemplated Transaction and the following ratio:

Share price before modification

Share price before modification - reduction per Share of the right to profits.

For the calculation of this ratio:

- the Share price before modification means the volume-weighted average of the prices of the Company’s Shares listed on the Trading Market during the last three trading days preceding the date of modification;

- the reduction by Share on the right to profits will be determined by an independent expert of international reputation appointed by the Company and will be submitted to the approval of the Holders’ General Meeting (as defined in Condition 7).

If however these preferred Shares are issued with shareholders’ preferential subscription rights or by free distribution of Warrants to subscribe to such preferred shares, the new Exercise Ratio will be adjusted in accordance to paragraphs 1 or 5 above.

(b) in case of creation of preferred shares without a modification in the distribution of profits, the adjustment of the Exercise Ratio that would be necessary will be determined by an independent expert of international reputation appointed by the Company.

If the Company were to carry out Transactions where an adjustment had not been completed under paragraphs 1 to 9 above, and a later law or regulations require an adjustment, the Company shall undertake such adjustment in accordance with the law or regulations then applicable and the market practice observed in France.

In the event of an adjustment, the new exercise conditions will be brought to the prompt attention of the Holders pursuant to Condition 12 within three Business Days of the effectiveness of the adjustment.

The Company’s Board of Directors will report the calculation and results of any adjustment in the annual report following such adjustment.

(i) the Company may modify its form or corporate purpose without the approval of the Holders’ General Meeting;
