i.the Trading Day following the conversion (whether through one or several conversions) or redemption of all the Notes that had been issued in connection with a previous Tranche; or

In order for the Investor to subscribe to the Notes, subject to the satisfaction of the conditions set forth in Clause 3.4, within two (2) Trading Days from the receipt of a Request in respect of a Subsequent Tranche, the Investor shall exercise the appropriate number of Note Warrants (i.e. 60 Note Warrants per Tranche, unless there has been a reduction in Tranche size in accordance with this Clause 3.1) by delivering to the Issuer a Note Warrant exercise notice in the form attached hereto as Schedule 3 (a "Note Warrant Exercise Notice"), the date of receipt of the Note Warrant Exercise Notice being the "Note Warrant Exercise Date".

The Note Warrant Exercise Price with respect to each Subsequent Tranche shall be paid by the Investor to the Issuer as follows:

–EUR 90,000 shall be paid by the Investor to the Issuer by way of set-off against the certain, liquid and due receivable amounting to EUR 90,000 (or EUR 45,000 if there has been a reduction in Tranche size in accordance with this Clause 3.1) held by the Investor against the Issuer corresponding to a part of the amount of the commitment fee with respect to the relevant Subsequent Tranche as provided for in Clause 3.5;

On each Closing Date, the Issuer shall procure the Agent to immediately update the securities accounts in which the Note Warrants, the Notes and the Warrants are registered to reflect the exercise of the Note Warrants, the registration of the Notes and, if applicable, the Warrants issued in the name of the Investor, and the payment of the Note Warrant Exercise Price.

The aggregate Principal Amount of the Notes issued under each Subsequent Tranche shall be equal

1 Each tranche corresponds to a specific bond issue.

to three million Euros (EUR 3,000,000) (unless the Investor exercises its right to decrease the Principal Amount of the Notes of a Subsequent Tranche in accordance with the last paragraph of this Clause 3.1, in which case the Principal Amount of the Notes to be issued under such Subsequent Tranche shall be equal to one million five hundred thousand Euros (EUR 1,500,000)).

Should the market capitalization of the Issuer on Euronext Paris (as measured by the Share price for the given day) be lower than EUR 50,000,000 for at least twenty (20) consecutive Trading Days at any time from the drawdown of the first Tranche until the expiry of the Commitment Period, the Investor shall temporarily have the right to reduce the Principal Amount of a Subsequent Tranche by fifty percent (50%) (i.e. the principal amount of the Tranche shall be reduced from EUR 3,000,000 to EUR 1,500,000). Such reduction of the Principal Amount of a Subsequent Tranche shall automatically lapse once the market capitalization of the Issuer (as measured by the Share price for the given day) has been higher than EUR 50,000,000. Upon exercise of such right by the Investor, the number of Tranches remaining available for issuance under this Agreement shall be adjusted upward accordingly so that the amount of the Commitment shall remain unchanged.

From July 15, 2020 (included) until the expiry of the Commitment Period, the Investor shall have the right to request the issuance of a Tranche (the "Investor Call") upon exercise of the relevant number of Note Warrants, by submitting a written notice in accordance with Clause 9.1 (an "Investor Call Notice") to the Issuer in the form attached hereto as Schedule 8.

The characteristics of the Notes are described in Schedule 4. Notes may be converted in accordance with Schedule 5. The Notes issued under each Tranche shall constitute a distinct bond issue under French law.

3.3 Warrants

Warrants in the total combined amount of ten percent (10%) of the Principal Amount of each Tranche (i.e. three hundred thousand Euros (EUR 300,000), or one hundred fifty thousand Euros (EUR 150,000) if there has been a reduction in Tranche size in accordance with Clause 3.1) and having the characteristics described in Schedule 6 shall be attached to the Notes issued pursuant to each Tranche. The number of Warrants that shall be attached to the Notes issued under each Tranche shall be equal to three hundred thousand Euros (EUR 300,000) (or one hundred fifty thousand Euros (EUR 150,000) if there has been a reduction in Tranche size in accordance with Clause 3.1), divided by the Warrant Exercise Price (the resulting number of Warrants being rounded down to the nearest whole number).

be so in compliance would not reasonably be expected, individually or in the aggregate, to materially affect its ability to perform its obligations, undertakings and commitments hereunder, or as disclosed in the Publicly Available Information.

4.1.2 The Issuer will do all reasonable things necessary to preserve and keep in full force and effect its corporate existence and the corporate existence of its Subsidiaries.

4.1.3 Once a contemplated merger of the Issuer with or into any other person or entity be disclosed to the investment community through a press release, the Issuer and the Investor shall discuss in good faith, within sixty (60) calendar days from such public announcement, the possibility to continue the Agreement or to implement a transaction similar to that contemplated hereunder within the surviving entity.

4.1.4 The Issuer will not sell, lease, transfer, liquidate or otherwise dispose of all or substantially all of its assets now owned or hereafter acquired in a single transaction (or a series of related transactions), except for fair consideration or on an arm's length basis.

4.1.5 The Issuer shall not drawdown any variable rate equity financings (such as equity lines) currently in place or participate in any variable rate equity financings in each case on Euronext Paris, unless the variable rate element of such financing (e.g. issuance of Shares, redemption into Shares, etc.) may only occur after the later of (x) the expiry date of the Commitment Period, or (y) the date on which any and all Notes funded under the Commitment shall have been fully converted.

For the avoidance of doubt, the provisions of the paragraph above do not prohibit the Issuer from raising funds by any other means, such as for example, the issuance of securities for which the conversion/redemption/exercise price is fixed and issuance of securities in ATM financings.

4.1.6 So long as any Note is outstanding, without the prior written approval of the Investor, which shall not be unreasonably withheld, the Issuer shall not contract, create, incur or suffer to exist any Indebtedness which would render the Notes subordinated contractually or by operation of law to such Indebtedness in right of payment of interest and principal and in an amount greater than EUR 20,000,000, other than the following:

i.the Notes;

ii.Indebtedness incurred in the normal course of business which existed on the Issuance Date (or any refinancing thereof);

iii.Indebtedness incurred for the purposes of acquiring an asset or a business (or any refinancing thereof);

iv.Indebtedness resulting from a sale and lease back arrangement on real estate property;

v.Indebtedness resulting from PGE (Prêt Garanti par l'Etat) and R&D loans granted by Bpifrance; and

vi.Indebtedness resulting from IFRS16 impacts on the accounts of the Issuer.

4.1.7 The Issuer shall not communicate to the Investor, any Note or Warrant holder as the case may be, any inside information ("information privilégiée") within the meaning of Article 7 of MAR, except if such information was expressly requested by the Investor in which case this covenant shall not apply. Should the Issuer be in breach of the aforesaid obligation, the Issuer shall, at the latest on the following Trading Day, make public said information to the investment community through a press release.

4.1.8 So long as any Note is outstanding, the Issuer shall not create or assume any Lien on its business ("fonds de commerce"), or on its shareholdings in a Subsidiary in order to secure Indebtedness incurred or guaranteed by it unless the Notes are equally and rateably secured therewith.

4.1.9 Notwithstanding the provisions of Clause 9.10 below, the Issuer shall provide to the Investor a draft of any press release (in French and in English) to be issued by the Issuer in connection with the Note Warrants, the Notes and/or the Warrants or in connection with this Agreement at the latest two (2) calendar days prior to its contemplated date of circulation. The Issuer shall:

i.announce the terms of this transaction in accordance with the requirements of the Euronext Paris rules, MAR and the AMF General Regulation; and

ii.make a public announcement in case of (a) exercise of an Investor Call by the Investor, or (b) delivery of a Request by the Issuer to the Investor, in each case as required by applicable laws and regulations.

4.1.10 As from the Issuance Date, the Issuer shall (i) make available on its website a table in order to follow-up the number of outstanding Note Warrants, Notes, Warrants and Shares issued upon conversion of the Notes and exercise of the Warrants (together with an update on the total number of Shares and voting rights in the Issuer) and (ii) update such table immediately after the receipt of any Note Warrant Exercise Notice, Conversion Notice and/or Warrant Exercise Notice sent by the Investor.

4.1.11 The Issuer will cause the Agent, acting as registrar (établissement financier en charge du suivi titres) of the Issuer, to list all Shares issued from time to time at the latest with effect from the opening of business on the third (3rd) Trading Day following their issuance.

4.1.12 The Issuer shall make any payment due to the Investor (or any of its Affiliates) under this Agreement within ten (10) Trading Days from the due date.

4.1.13 On each Conversion Date, the Issuer shall calculate if the aggregate number of Shares corresponding to the sum of :

a.the Principal Amount of the outstanding Notes divided by the Closing VWAP on such Conversion Date;

b.the number of Shares to be issued upon exercise of any outstanding Warrants (if any); and

c.the aggregate number of Shares issued by the Issuer without any approval of prospectus by the AMF for the admission of such Shares on Euronext Paris over the last twelve (12) months,

would theoretically result in the admission to trading on Euronext Paris of a total number of Shares exceeding the limits of the listing prospectus exemption provided for by Article 5.(a) of Regulation (EU) 2017/1129 dated June 14, 2017, in which case (x) the Issuer shall immediately notify it by e-mail with acknowledgement of receipt to the Investor, and (y) the Conversion Notice at stake shall be automatically deemed withdrawn by the Investor.

4.2 Covenant of the Investor

The Investor covenants and agrees, in respect of the period from the Issuance Date until the later of (i) the expiry date of the Commitment Period and (ii) the date on which the Shares are no longer listed on Euronext Paris or on any other regulated market, not to send, as from the receipt of any notification made by the Issuer to the Investor in accordance with Clause 4.1.13, any Conversion Notice to the Issuer that would result in the admission to trading on Euronext Paris of a total number of Shares exceeding the limits of the listing prospectus exemption provided for by Article 5.(a) of Regulation (EU) 2017/1129 dated June 14, 2017.

3.2 To be effective vis-à-vis the Issuer, any transfer of the Notes shall be registered in the securities accounts and the transferor shall be deemed to be the holder of such Notes until the name of the transferee is entered into the securities accounts in respect thereof.

3.3.

Each Note shall have a nominal value of EUR 50,000.

6.Interest

7.3 At the Note holder's discretion, the Issuer is required to early redeem in cash, within three (3) Trading Days following the receipt of a notice sent to it by the Note holder, all or any Notes held by the applicable Note holder in case of occurrence of a Change of Control or an Event of Default under the Agreement.

In the event of redemption in cash in case of occurrence of a Change of Control or an Event of Default under the Agreement, the Issuer shall pay to each Note holder one hundred and five percent (105%) of the aggregate outstanding principal amount of its Notes, in accordance with Paragraph 8 of this Schedule 4.

8.Conversion: Termination of Conversion Rights

8.1 Conversion of the Notes into Shares of the Issuer; Conversion Period

Unless it has terminated its conversion rights pursuant to Paragraph 8.5 of this Schedule 4, each Note holder shall have the right at any time as of any Closing Date, up to and including the Maturity Date (the "Conversion Period"), to convert all or any of the Notes into new or existing Shares, at the sole discretion of the Issuer, and to determine the number of Notes to be converted, and the corresponding aggregate principal amount so converted (the "Conversion Amount").

At the Issuer's option, the Issuer shall have then the right, upon receipt of a Conversion Notice sent by the Note holder, to:

i.deliver new or existing Shares of the Issuer to the Note holder in accordance with the provisions of Paragraph 8.3 of this Schedule 4; or

ii.pay to the Note holder one hundred percent (100%) of any Conversion Notice, in cash, calculated as per the following formula (the "Conversion Cash Payment"):

Reimbursement = (Conversion Amount/Conversion Price)*Closing VWAP on the Conversion Date

Each Note holder is allowed to convert any Notes as long as it stays within the outstanding Principal Amount, it being specified that each Note may only be converted at one go.

8.2 Conversion Date; Notice

Each Note holder may convert all or any of its Notes on any Trading Day of its choice during the Conversion Period, effective at the date of receipt by the Issuer of a Conversion Notice in accordance with Paragraph 8.1 of this Schedule 4 (the "Conversion Date").

On each chosen Conversion Date, each Note holder shall convert all or any of its Notes by giving Notice to the Issuer (the "Conversion Notice"), using the form attached in Schedule 5 and specifying a number of Notes to be converted and the corresponding Conversion Amount in accordance with Paragraph 8.1 of this Schedule 4.

If the Issuer has not elected for the Conversion Cash Payment, the Issuer, after updating the securities account where the Notes are registered, shall in turn send a notice to the Agent for the issuance of new Shares to the relevant Note holder.

The Shares upon conversion shall be issued in bearer form and shall be transferred by the Agent to the Investor's custodian account within two (2) Trading Days following the Conversion Date (with a best efforts undertaking from the Issuer to have this completed within one (1) Trading Day from the Conversion Date provided that the Conversion Notice is received before 3pm Paris time on the Conversion Date). The Agent shall liaise with the custodian of the Investor to ensure prompt delivery.

8.3 Conversion Ratio

If the Issuer has not elected for the Conversion Cash Payment, the number of new Shares issued by the Issuer to the relevant Note holder upon conversion of one or several Notes in accordance with Paragraph 8.1 of this Schedule 4 will be calculated as the Conversion Amount divided by the Conversion Price.

If the issuance of new Shares would result in the issuance of a fraction of a Share, the Issuer shall round such fraction of a Share up to the nearest whole Share.

The new Shares shall be fully paid by set-off against the Conversion Amount that will come in deduction from the Principal Amount. Such conversion shall not require the payment of any fee or charge by the relevant Note holder.

The Issuer shall promptly deliver freely tradable Shares or the Conversion Cash Payment to the relevant Note holder upon each conversion of Note(s). The issuance of the Shares and their admission to trading on Euronext Paris (or the remittance of existing Shares, as the case may be) shall occur no later than two (2) Trading Days after the Conversion Date (with a best efforts undertaking from the Issuer to have this completed within one (1) Trading Day from the Conversion Date provided that the Conversion Notice is received before 3pm Paris time on the Conversion Date). The reception of the Conversion Cash Payment by the relevant Note holder shall occur no later than two (2) trading days after the Conversion Date.

Upon conversion of Notes, if the Issuer has not elected for the Conversion Cash Payment and if the relevant Note holder does not receive the relevant Shares as provided for in the paragraph above, the Issuer shall pay to the relevant Note holder an amount equal to the difference (if positive) between the closing price of the Share one (1) Trading Day after the Conversion Date and the closing price of the Share on the day immediately prior to the date on which the relevant Shares are effectively received by the relevant Note holder, for each new Share which was issued upon the relevant conversion of Notes.

Subject to the right of the Issuer to use an existing additional delegation to the Board of Directors granted by another shareholders' general meeting of the Issuer than the EGM in order to continue the financing program (in which case the Parties shall agree in good faith to amend the Agreement and the Notes to the extent necessary), if the Issuer does not have sufficient shareholders' authorizations available to issue new Shares to a Note holder upon conversion of Notes, and if the early redemption of the Notes was not requested by the relevant Note holder, at the Note holder's discretion, the relevant Notes shall be acquired by the Issuer, on the Trading Day following the Conversion Date, for a price equal to the number of new Shares which should have been issued to it upon conversion of the Notes multiplied by the closing price of the Share on the day prior to the Conversion Date. Such acquired Notes shall then be cancelled by the Issuer.

Any payment to a Note holder made by the Issuer in accordance with Paragraph 8.3 of this Schedule 4 shall be made by the Issuer to the relevant Note holder in cash, by wire transfer to a bank account notified by the relevant Note holder to the Issuer, in immediately available, freely transferable funds in Euros.

8.4 Rights attached to the Shares

The new Shares issued upon conversion of the Note(s) shall be subject to all provisions of the By-Laws and to decisions of the general meetings of the shareholders of the Issuer. The new Shares shall be admitted to trading on Euronext Paris as from their issuance, will carry immediate and current dividend rights ("jouissance courante") and will be fully assimilated to and fungible with the existing Shares.

8.5 Termination of Conversion Right

The right of each Note holder to convert the Notes pursuant to this Paragraph 8 shall terminate on the date on which the Notes are fully converted.

9.Representation of the Note holders

9.1 As long as the Notes are held by a single holder, such holder shall exercise under its own name all rights and powers granted by the French Commercial Code to the "Masse" within the meaning of Article L. 228-103 of the French Commercial Code.

9.2 As soon as the Notes having the same characteristics and being fungible are held by more than one holder, the holders shall appoint a representative of the "Masse" in accordance with Articles L. 228-47 and L. 228-103 of the French Commercial Code.

9.3 Where applicable, the rights of Note holders will be exercised in accordance with Article L. 228- 103 paragraph 1 of the French Commercial Code.

3.Assignment, transfer and absence of admission to trading of the Warrants

3.1 The Warrants may be assigned or transferred without the prior consent of the Issuer, only to Affiliates of the Investor, subject to the prior information of the Issuer and being provided that such Affiliate undertakes irrevocably, prior to this transfer, to retrocede the Warrants in question and/or the Shares issued pursuant to the exercise of such Warrants to the Investor when this Affiliate ceases to be an Affiliate of the Investor.

3.2 To be effective vis-à-vis the Issuer and third parties, any transfer of Warrants shall be registered in the securities accounts and the transferor of any Warrants shall be deemed to be the holder of such Warrants until the name of the transferee is entered into the securities accounts in respect thereof.

3.3 Any transferee that becomes a Warrant holder, by whatever means and for whatever reason, shall have the benefit of, and be subject to, all of the rights and obligations arising under this Agreement, provided that such permitted transferee shall represent that it falls within the category of investors described in the EGM Resolution and to which the Note Warrants issuance has been reserved to (i.e. that the Investor is a natural or legal person, including company, trust or investment fund, organized under French or foreign law, that regularly invest in the pharmaceutical, biotechnological or medical technology sector).

3.4 The Warrants will not be admitted to trading on any financial market.

4.Term

Each Warrant holder is allowed to make multiple exercises of Warrants.

5.2 Exercise Date; Exercise Notice

5.3 Exercise Ratio - Exercise Price

Each Warrant will give right to one (1) Share (the "Warrant Exercise Ratio") subject to any adjustment made in accordance with Paragraph 7 of this Schedule 6.

The new Shares resulting from the exercise of the Warrants shall be issued upon payment in cash by the relevant Warrant holder of the Warrant Exercise Price.

Such exercise shall not require the payment of any additional fee or charge by the relevant Warrant holder.

The Issuer shall promptly deliver freely tradable Shares to the relevant Warrant holder upon each exercise of Warrant(s). The issuance of the Shares and their admission to trading on Euronext Paris shall occur no later than two (2) Trading Days after the Warrant Exercise Date. The reception of the Warrant Exercise Price shall occur no later than 3pm Paris time two (2) trading days after the Warrant Exercise Date.

Subject to the right of the Issuer to use an existing additional delegation to the Board of Directors granted by another shareholders' general meeting of the Issuer than the EGM in order to continue the financing program (in which case the Parties shall agree in good faith to amend the Agreement and the Warrants to the extent necessary), if the Issuer does not have sufficient shareholders' authorizations available to issue new Shares to a Warrant holder upon exercise of a Warrant, the exercised Warrant shall be acquired by the Issuer, on the Trading Day following the relevant Warrant Exercise Date, for a price equal to (i) the Warrant Exercise Ratio multiplied by (ii) the difference between (a) the closing price of the Share on the day prior to the Warrant Exercise Date and (b) the Warrant Exercise Price, as the case may be, divided by the Warrant Exercise Ratio. Such acquired Warrants shall be cancelled by the Issuer.

Any payment to a Warrant holder made by the Issuer in accordance with Paragraph 5.3 of this Schedule 6 shall be made by the Issuer to the relevant Warrant holder in cash, by wire transfer to a bank account notified by the relevant Warrant holder to the Issuer, in immediately available, freely transferable funds in Euros.

6.2 As soon as the Warrants having the same characteristics and being fungible are held by more than one holder, the holders shall appoint a representative of the "Masse" in accordance with Articles L. 228-47 and L. 228-103 of the French Commercial Code.

For the avoidance of doubt, if certain of the Warrants no longer have the same characteristics, there will be several "Masses".

6.3 Where applicable, the rights of Warrant holders will be exercised in accordance with Article L. 228-103 paragraph 1 of the French Commercial Code.

7.Protection of the Warrant holders

7.1 Upon completion of any of the following transactions:

1.issue of securities carrying a preferential subscription right to shareholders,

2.increase in share capital by capitalisation of reserves, profits or share premia, and by distribution of free shares, or stock split or reverse stock split,

3.in the event that a nominal value is assigned to the Shares, an increase in share capital of the Issuer, without issuing Shares, by capitalisation of reserves, profits or share premia by increasing the nominal value of the Shares,

4.distribution of reserves in cash or in kind or a share premium,

5.allotment of bonus financial instruments other than Shares,

6.merger by acquisition (fusion par absorption), merger (fusion par création d'une nouvelle société), spin-off, division (scission) of the Issuer,

7.buy-back of own Shares at a price that is higher than the Share price,

8.amortisation in share capital of the Issuer,

9.modification of the Issuer's allocation of its profits,

which the Issuer may carry out after the detachment date of the Warrants, the rights of the Warrants holders will be protected by adjusting the Warrant Exercise Ratio and the Warrant Exercise Price in accordance with the following provisions.

In the event of an adjustment carried out in accordance with conditions 1 to 9 below, the new Warrant Exercise Ratio or Warrant Exercise Price will be determined to one decimal place and rounded down to the nearest 10th (0.15 being

rounded up to the next highest 10th). Any subsequent adjustments will be carried out on the basis of such newly calculated and rounded Warrant Exercise Ratio. However, the Warrants can only result in the delivery of a whole number of Shares.

1.In the event of a financial transaction, conferring a preferential subscription right to existing shareholders, the new Warrant Exercise Ratio will be determined by multiplying the Warrant Exercise Ratio in effect prior to the relevant transaction by the following formula:


share value ex-subscription right plus the value of the subscription right
share value ex-subscription right

For the purposes of calculating this formula, the values of the share ex-subscription right and of the subscription right will be determined on the basis of the average of the opening prices of the Shares on Euronext Paris (as reported by Bloomberg) falling in the subscription period during which the Shares and the subscription rights are listed simultaneously.

2.In the event of an increase in share capital of the Issuer by capitalisation of reserves, profits or share premia and by distribution of free shares, or in the event of a stock split or a reverse stock split the new Warrant Exercise Ratio will be determined by multiplying the Warrant Exercise Ratio in effect prior to the relevant transaction by the following formula:


Number of shares after the transaction
Number of shares existing before the transaction

3.In the event of an increase in share capital of the Issuer without Shares being issued by means of a capitalisation of reserves, profits or share premia performed by increasing the nominal value of the Shares, the nominal value of the Shares which may be delivered to the Warrants holders upon exercise of their Warrants will be increased accordingly.

4.In the event of the distribution by the Issuer of reserves in cash or in kind or a share premium, the new Warrant Exercise Ratio will be determined by multiplying the Warrant Exercise Ratio in effect prior to the relevant transaction by the following formula:


1
1 -			Amount of the distribution per share
			Value of the share before distribution

For the purposes of calculating this formula, the value of the Shares before distribution will be determined on the basis of the weighted average of the prices on Euronext Paris over the last three (3) Trading Days before the distribution.

5.In the event of an allotment of bonus financial instruments other than Shares of the Issuer, the new Warrant Exercise Ratio will be determined as follows:

•If the right to receive financial instruments is listed on Euronext Paris, the new Warrant Exercise Ratio will be determined by multiplying the Warrant Exercise Ratio in effect prior to the relevant transaction by the following formula:


1 +			Price of the right to receive financial instruments
			Share price ex-right

For the purposes of calculating this formula, the prices of the Shares ex-right and of the rights to receive financial instruments will be determined on the basis of the weighted average of the prices on Euronext Paris over the first three (3) Trading Days as from the detachment of the financial instruments.

•If the right to receive financial instruments is not listed on Euronext Paris, the new Warrant Exercise Ratio will be determined by multiplying the Warrant Exercise Ratio in effect prior to the relevant transaction by the following formula:


1 +			Value of the financial instruments allocated to each shares
			Share price ex-right

For the purposes of calculating this formula, the price of the Shares ex-right and the value of the financial instruments will be determined on the basis of the weighted average of the prices on Euronext Paris over the first three (3) Trading Days as from the detachment of the financial instruments.

If the financial instruments allocated are not listed on Euronext Paris, their value shall be evaluated in an independent expert's certificate. This certificate shall be produced by an expert of international repute appointed by the Issuer, whose opinion shall not be subject to appeal.

6.In the event of merger by acquisition (fusion par absorption) of the Issuer by another company or of merger of the Issuer with one or more other companies to create a new company (fusion par création d'une nouvelle société), or in the event of a division (scission) or spin-off of the Issuer, the Warrants may be exercised into shares of the acquiring or new company or the companies resulting from any division or spin-off

The new Warrant Exercise Ratio shall be determined by adjusting the Warrant Exercise Ratio in effect before such event by the exchange ratio of the Issuer's Shares against the shares of the acquiring or new company or companies resulting from any division or spin-off. These companies shall be substituted to the Issuer in order to apply the above adjustment, the purpose being to maintain, where applicable, the rights of the Warrants holders in the event of financial or securities transactions, and, generally to ensure that the rights of the Warrants holders are guaranteed under the legal, regulatory and contractual conditions.

7.In the event that the Issuer makes an offer to the shareholders to buy-back its own Shares at a price that is higher than the Share price, the new Warrant Exercise Ratio will be determined by multiplying the Warrant Exercise Ratio in effect by the following formula calculated to the nearest 100th of a Share:


Share value + pc% x (buy-back price - share value)
Share value

For the purposes of calculating this formula:

"Share value" means the volume-weighted average of the prices of the Shares listed on Euronext Paris during the three last trading days preceding the buyback (or the ability of buyback).

"Pc%" means the percentage of the share capital of the Issuer that has been bought back.

"Buy-back price" means the effective price of the Shares bought-back (which is by definition higher than the Share value).

8.In the event of an amortisation in share capital of the Issuer, the new Warrant Exercise Ratio will be determined by multiplying the Warrant Exercise Ratio in effect prior to the relevant transaction by the following formula:


1
1 -			Amount of amortisation per share
			Value of the share before amortisation

For the purposes of calculating this formula, the value of the Share before the amortisation will be determined on the basis of the volume-weighted average of the prices of the Share on Euronext Paris over the last three (3) Trading Days immediately prior to the date of the amortisation.

9.In the event of the modification by the Issuer of the allocation of its profits as a result of the issue of preference shares, the new Warrant Exercise Ratio will be determined by multiplying the Warrant Exercise Ratio in effect prior to the preference share issue date by the following formula:


1
1 -			Reduction of the profit right per share
			Value of the share before modification

For the purposes of calculating this formula, the Share price before the modification of the allocation of profits will be determined on the basis of the volume-weighted average of the prices of the Share on Euronext Paris over the last three (3) Trading Days immediately prior to the date of the modification.

7.2 Any Warrants holder exercising its rights may subscribe to a number of Shares, which is calculated by multiplying the Warrant Exercise Ratio in effect at such time by the number of the Warrants exercised. If the Shares are listed and if the number of Shares calculated in this manner is not a whole number, a Warrant holder shall receive:

•either the nearest whole number of Shares immediately less than its entitlement and will receive a payment equal to the value of such additional fraction of a Share calculated on the basis of the closing Share price listed on Euronext Paris on the Warrant Exercise Date;

•or the nearest whole number of shares immediately more than its entitlement and will provide a payment equal to the value of such additional fraction of a Share calculated on the basis of the closing Share price listed on Euronext Paris on the Warrant Exercise Date.

Notwithstanding the above, the Issuer shall not be permitted, without the prior authorisation of the Warrants holder(s), to change its legal form or corporate purpose.
