4. SHARE CAPITAL OF THE COMPANY

4.1 General

As of this day, Nabriva’s registered share capital (Nennkapital) consists of 327,522 (three hundred twenty seven thousand five hundred twenty two) shares which are divided, on a contractual basis but not pursuant to the Company’s articles of association, into 84,102 (eighty four thousand one hundred and two) common shares (the Common Shares), and 243,420 (two hundred forty three thousand four hundred and twenty) Preferred A Shares.

28,311 (twenty eight thousand three hundred eleven) additional shares could be issued out of conditional capital (bedingtes Kapital) on the basis of a stock option scheme in favor of the Company’s employees, the Company’s management, selected members of the Company’s supervisory board and further participants. Furthermore, 135,450 (one hundred thirty five thousand four hundred fifty) additional shares could be issued out of conditional capital (bedingtes Kapital) to lenders under the existing convertible loan agreements between the Company and certain of its shareholders or their Affiliates in the event of a conversion of the claims for repayment of the loans granted to the Company pursuant to the terms and conditions of such convertible loan agreements.

Finally, 3,281 (three thousand two hundred eighty one) additional shares could be issued out of authorized capital (genehmigtes Kapital) granted by the Company’s shareholders to fulfill the Company’s obligations vis-à-vis Kreos Capital IV (UK) Ltd.

After implementation of the First Tranche of the share capital increase pursuant to the Subscription Agreement 3, the registered share capital of the Company will amount to EUR 1,057,684 (Euro one million fifty seven thousand six hundred and eighty four) and will be fully paid-in; after implementation of the Second Tranche of the share capital increase, if any, pursuant to the Subscription Agreement 3, the share capital of the Company will amount to EUR 1,799,877 (Euro one million seven hundred and ninety nine thousand eight hundred and seventy seven), subject to adjustment as described in section 2.2.1 of the Subscription Agreement 3, and will be fully paid-in.

All Shares shall carry equal rights, except as provided for in this Shareholders Agreement 2015.

For the purposes of this Shareholders Agreement 2015, the Shares held by the Initial Investors initially before the implementation of the Subscription Agreement 2 and the Sandoz Preferred A Shares, subject to the terms and conditions of this Shareholders

16

Agreement 2015, their successors and assignees shall be defined as the Preferred A Existing Shares and (i) the Shares held initially by Sandoz (other than Sandoz Preferred A Shares), (ii) the Shares held by Rodger Novak and Gerd Ascher, (iii) the treasury shares held by the Company to fulfill its obligations under the stock option scheme in favor of the Company’s employees, the Company’s management, selected members of the Company’s supervisory board, further participants and the founder’s program, (iv) any Preferred A Shares converted into shares with the same rights and obligations as the Shares held initially by Sandoz, (other than Sandoz Preferred A Shares), and (v) the Shares subscribed for by the Guernsey Trust in the course of the capital increase pursuant to the Subscription Agreement 2, shall together be defined as the Common Shares.

The Shares subscribed to by the Initial Investors (except for Chiswell) in the course of the two tranches of the capital increase pursuant to the Subscription Agreement 2 shall be referred to as Preferred A Extension Shares and together with the Preferred A Existing Shares the Preferred A Shares.

The Shares issued in the course of the First Tranche pursuant to the Subscription Agreement 3 shall be referred to as Preferred B-1 Shares; and the Shares issued in the course of the Second Tranche, if any, pursuant to the Subscription Agreement 3 shall be referred as Preferred B-2 Shares. The Preferred B-1 Shares and the Preferred B-2 Shares shall be referred to as the Preferred B Shares; and the Preferred B Shares together with the Preferred A Shares, the Preferred Shares.

Without prejudice to the provisions of section 6, the transfer of Shares is subject to the prior approval of the Shareholders Meeting (as defined below) which requires a simple majority resolution (Vinkulierung). The Shareholders Meeting must, however, give its approval if the provisions of section 6 are complied with; the Parties undertake to exercise their respective voting rights respectively.

4.2 Voting Rights

For each EUR 1 of the registered share capital represented by a Common Share, the respective Shareholder shall have 1 (one) vote.

Each holder of a Preferred Share shall, with respect to the Preferred Share held by it, have such number of votes equal to the number of votes attached to the Common Share such holder would hold had it converted its Preferred Share at the date of such shareholders’ resolution at the then applicable Conversion Rate in a Voluntary Conversion, irrespective whether such Voluntary Conversion actually takes place. To the extent permitted by Austrian corporate law, the holders of Common Shares in such case shall waive the respective part of their voting right in order to provide the holders of Preferred Shares with the amount of additional votes required pursuant to this provision.

17

4.3 Preferred Dividend Rights

4.3.1 Preferred Dividend and Preferred Dividend Event

Each holder of a Preferred B Share shall be entitled to receive, in preference to the holders of Common Shares and Preferred A Shares, an annual preference dividend of 8% (eight percent) of the Preferred B-1 Purchase Price or Preferred B-2 Purchase Price respectively (as applicable), for each Euro of the registered share capital represented by its respective Preferred B Shares (the Preferred Dividend), for each business year, including, on a pro rata basis based on the actual days elapsed from and after the date of issuance of each Preferred B Share, for the business year in which such Preferred B Shares are issued, only when, if and as declared by the Company’s shareholders’ meeting, and if declared shall only be payable to the holders of Preferred B Shares upon (i) a Liquidation Event in accordance with section 4.4, (ii) a conversion in accordance with section 4.5, (iii) a Redemption in accordance with section 4.8, or (iv) a resolution of the Shareholders Meeting regarding Preferred Dividends (each a Preferred Dividend Event). If a Preferred Dividend Event takes place during a business year, the Preferred Dividend for the respective business year shall be calculated pro rata based on the actual days elapsed in such business year until the date of the Preferred Dividend Event. The Company shall, in the event of a Liquidation Event or conversion pursuant to section 4.5.2(i), provide each holder of Preferred B Shares written notice at least ten (10) days before a Preferred Dividend Event. All Shareholders hereby covenant to vote in favor of, consent to or otherwise approve the payment of any and all declared but unpaid Preferred Dividends, if any, upon any Preferred Dividend Event, as may be required under Austrian or other applicable law.

4.3.2 Payment of Preferred Dividend

In the case of a Preferred Dividend Event, the holders of Preferred B Shares as a group shall be entitled upon a resolution of the Preferred B Shareholders holding 60% or more of the Preferred B Shares to opt for one of the following options:

(a) Cash payment of the amount of all declared but unpaid Preferred Dividends, if any, by the Company within 14 (fourteen) days following the Company’s receipt of the resolution of the Preferred B Shareholders, to the extent permitted by law and the Company provides for a sufficient amount of distributable profits; or

(b) The subscription for that number of additional Shares calculated by dividing the value of all declared but unpaid Preferred Dividends, if any, by the Fair Market Value per Preferred B Share at the time of any Preferred Dividend Event, which such additional Shares shall be distributed pro rata among the holders of Preferred B Shares on an as-converted to Common Shares basis. Such additional Shares shall be furnished with all rights of the Preferred B

18

Shares, if any at the time of such Preferred Dividend Event. For the purposes of this section 4.3.2(b), Fair Market Value means the value of one Preferred B Share as (i) agreed to among the Company and either the Requisite New Investors or at the holders of at least 60% of the then-outstanding Preferred B Shares, or (ii) if the Fair Market Value has not been agreed upon within ten (10) days following the Company’s receipt of the resolution of the Preferred B Shareholders, determined by an independent auditor mutually acceptable to the Company and either the Requisite New Investors or the holders of at least 60% of the then-outstanding Preferred B Shares, the costs of which shall be bourne by the Company, provided, however, that the Fair Market Value shall be reduced by an amount equal to any per-share amount paid by the holders of the Preferred B Shares in connection with the issuance of additional Shares pursuant to this section 4.3.2(b), including any payments required in connection with any ordinary share capital increase. Any such additional Shares shall be created, to the extent possible and legally permitted, (A) by issuing new Preferred B Shares according to the Austrian Act of Capital Adjustment (Kapitalberichtigungsgesetz) or otherwise (B) by issuing new Preferred B Shares by way of an ordinary share capital increase against payment of EUR 1 (Euro one) for each EUR 1 (Euro one) of the nominal share capital increased. For the avoidance of doubt, the amount of declared but unpaid Preferred Dividends shall be reduced by an amount corresponding to the value of the new Preferred B Shares issued. The Parties agree to vote in favor of any such share capital increase, whether pursuant to the Austrian Act of Capital Adjustment or by way of an ordinary share capital increase, and to waive their subscription right, to the extent they are not permitted or entitled pursuant to this Agreement to subscribe to such new Preferred B Shares. All holders of Common Shares and Preferred A Shares agree to transfer all the new Preferred B Shares received by them (pursuant to Austrian law and under the terms of this section 4.3.1(b)), to the existing holders of Preferred B Shares without payment and in such proportions that correspond with the number of Preferred B Shares held by each holder of Preferred B Shares immediately prior to a capital increase according to the terms of this section 4.3.2(b).

For the avoidance of doubt, the preferred dividend rights of the Preferred A Shareholders provided for in any of the Existing Agreements are herewith cancelled and terminated and, hence, any entitlement of the Preferred A Shareholders to any dividend accrued is permanently extinguished effective immediately.

4.3.3 Survival

Notwithstanding anything to the contrary in this Agreement, including section 11, sections 4.3.1 and 4.3.2 shall only terminate on the date that (a) no Preferred B Shares remain outstanding and (b) all declared Preferred Dividends, if any, have been fully paid and, if applicable, the additional Shares have been registered and issued to the holders of Preferred B Shares, in accordance with section 4.3.2.

19

4.3.4 Other Dividends

The holders of Preferred Shares and the holders of Common Shares shall be entitled to participate pro rata on any dividends declared by a resolution of the Shareholders Meeting and paid by the Company outside of a Preferred Dividend Event; the entitlement of the Shareholders in such dividend shall be determined on the basis as if all Shares would have been converted into Common Shares. For the avoidance of doubt such a dividend declared under this section 4.3.4 shall be paid in cash.

4.4 Liquidation Preference

4.4.1 Liquidation Event

(a) For the purposes of this Agreement, each of the following events shall be deemed a Liquidation Event:

(i) an exclusive license of or the sale, the lease or other disposal of all or substantially all of the assets of the Company;

(ii) a sale or other disposal (for the avoidance of doubt, the term disposal shall not include a pledge) in any transaction or series of transactions to which the Company is a party of 50% or more of the voting power of the Company, other than any transaction or series of transactions principally for bona fide equity financing purposes in which cash is received by the Company or indebtedness of the Company is cancelled or converted, or a combination thereof;

(iii) a merger or consolidation of the Company with or into any third party, other than any merger or consolidation in which the Shares of the Company immediately preceding such merger or consolidation continue to represent a majority of the voting power of the surviving entity immediately after the closing of such merger or consolidation; and

(iv) a liquidation, winding up or any other form of dissolution of the Company.

(b) An event specified in section 4.4.1(a) shall only be deemed a Liquidation Event if effected prior to a Qualified Public Offering. Upon a Qualified Public Offering, the Liquidation Preference shall terminate. The Company shall ensure that the definitive agreement for any such transaction constituting a Liquidation Event provides that the consideration payable to the shareholders of the Company in connection therewith will be allocated among the holders of the Company’s capital stock in accordance with this section 4.4.

20

For the purposes of this Agreement, the proceeds of any such Liquidation Event shall be the consideration and/or other proceeds received by (i) the Company or (ii) the Shareholders as a result of such Liquidation Event. If the Liquidation Event is a merger or consolidation pursuant to subsection 4.4.1(a)(iii) above or if the consideration and/or other proceeds are in a form other than cash, the consideration received shall be valuated pursuant to the procedure set out in section 6.3.2.

4.4.2 Liquidation Preference

Upon occurrence of a Liquidation Event, the proceeds of such Liquidation Event available for distribution shall be distributed as follows (the Liquidation Preference Rights):

(a) The holders of Preferred B Shares shall be entitled to receive, out of the proceeds or assets of the Company available for distribution and in preference to the holders of Preferred A Shares and Common Shares, an amount equal to (a) one (1) times the Preferred B-1 Purchase Price for each Preferred B-1 Share held by such holders and (b) two (2) times the Preferred B-2 Purchase Price for each Preferred B-2 Share held by such holders, if any, in each case to the extent already paid by such New Investor to the Company, plus for all Preferred B Shares then outstanding, all declared but unpaid Preferred Dividends at the date of the Liquidation Event, if any (in total the Liquidation Preference Amount). The Liquidation Preference Amount shall not be abrogated or diminished in the event a part of the proceeds of a Liquidation Event is subject to escrow, earn out or similar features in connection with a Liquidation Event. The holders of Preferred B Shares shall be entitled to receive the greater amount such holders would receive either as holders of Preferred B Shares or had they converted their Shares into Common Shares, after taking into account the effect of escrows, earn outs and other similar features;

(b) If there are insufficient proceeds available for distribution to pay the Liquidation Preference Amount in full to all holders of Preferred B Shares, the total proceeds, if any, available for distribution shall be paid to the holders of Preferred B Shares on a pro rata basis based on the portion of the full Liquidation Preference Amount to which each such holder would otherwise be entitled, and the Preferred B Shares shall in any event have preference over the Preferred A Shares and the Common Shares with respect to any distributions made upon the occurrence of a Liquidation Event.

(c) After such payment of the Liquidation Preference Amount has been made pursuant to section 4.4.2(a) above, and therefore in addition to the Liquidation Preference Amount, the remaining proceeds or assets of the Company legally available for distribution, if any, shall be distributed ratably to the holders of Preferred B Shares, the holders of Preferred A Shares and the holders of Common Shares, on the basis as if all Shares have been converted into

21

Common Shares. Notwithstanding the foregoing, with respect to the aggregate portion of proceeds or assets of the Company distributable to the holders of Preferred A Shares and the holders of Common Shares, such proceeds or assets of the Company shall be distributed as follows:

(i) the holders of Preferred A Shares shall be entitled to receive, out of the remaining proceeds or assets of the Company available for distribution to the holders of Preferred A Shares and Common Shares and in preference only to the holders of Common Shares (and without reducing the pro rata interest of the Preferred B Shareholders in the remaining proceeds), an amount equal to (i) 2 (two) times the Preferred A Purchase Price for each Preferred A Existing Share held by such holders and (b) 1 (one) time the Preferred A purchase Price for each Preferred A Extension Share held by such holders, in each case to the extent already paid by such holder of Preferred A Shares to the Company (the Total A Liquidation Preference Amount)

(ii) After payment of the Total A Liquidation Preference Amount has been made, and therefore in addition to the Total A Liquidation Preference Amount, the holders of Preferred A Existing Shares and Preferred A Extension Shares shall be entitled to receive pro rata with the holders of Common Shares the amount of any remaining proceeds or assets of the Company then available for distribution to the holders of Preferred A Shares and Common Shares (the Preferred A Pro Rata Amount and together with the Total A Liquidation Preference Amount the Series A Preferred Return Amount).

(d) If there are insufficient proceeds available for distribution to pay the Total A Liquidation Preference Amount in full to all holders of Preferred A Shares, the total proceeds, if any, available for distribution to the holders of Preferred A Shares and Common Shares (and, for the avoidance of doubt, after payment of the Liquidation Preference Amount and all other distributions to which the holders of Preferred B Shares are entitled pursuant to this section 4.4.2) shall be paid to the holders of Preferred A Shares based on the portion of the full Total A Liquidation Preference Amount to which each such holder would otherwise be entitled, and the Preferred A Shares shall in any event have preference over the Common Shares with respect to the Total A Liquidation Preference Amount:

(e) If the proceeds available for distribution to pay the Series A Preferred Return Amount in total exceed EUR 120 million (Euro one-hundred and twenty million), the holders of Preferred A Shares shall be entitled to receive pari passu with the holders of Common Shares (as if they were all holders of the same class of Shares and as if for the purpose of calculating such entitlements

22

all rights of conversion had been exercised in full) the proceeds available for distribution, provided, however, that if as a result of such pari passu distribution of proceeds the holders of Preferred A Shares receive less than the Series A Preferred Return Amount with a value of EUR 120 million (Euro one-hundred twenty million), the holders of Preferred A Shares shall be entitled to receive, in preference to any holder of Common Shares, the amount equal to their applicable Series A Preferred Return Amount with a value of EUR 120 million (Euro one-hundred twenty million) and thereafter the remaining proceeds shall be distributed to the holders of Common Shares pro rata the total shareholding represented by Common Shares.

4.4.3 Partial Liquidation

In case the Liquidation Event results (i) from an exclusive license of less than 100% (one hundred percent) of the assets of the Company, (ii) from a sale of less than 100% (one hundred percent) of the assets of the Company, or (iii) from a sale of less than 100% (one hundred percent) of the shares of the Company, all Parties participating in such sale shall participate and/or dispose of their Shares on a pro rata basis and the sales proceeds shall be distributed amongst such Parties participating in such sale pursuant to the calculation of the Liquidation Preference pursuant to section 4.4.2 whereby the implied value of 100% (one hundred percent) of the assets and/or the Shares of the Company shall be used for such calculation. In each such case, the remaining assets and/or shares not covered by such partial liquidation shall be deemed the new 100% basis for determining whether and to what extent a subsequent Liquidation Event occurs pursuant to this section 4.4.

4.4.4 Termination

Upon the conversion of any Preferred Shares pursuant to section 4.5, all Liquidation Preference Rights attached to such converted Preferred Shares shall automatically cease.

4.5 Conversion into Common Shares

4.5.1 Voluntary Conversion Right

Each holder of Preferred Shares shall be entitled at any time to waive its preferential rights set out in this Agreement (the Preference Rights) so that such holder of Preferred Shares shall thereafter be furnished with the same shareholder rights as the holders of Common Shares (a Voluntary Conversion). A Voluntary Conversion may be triggered with respect to all Preferred Shares held by such Investor or any part thereof, provided, however, that a Voluntary Conversion may only be triggered with respect to whole shares of Preferred Shares. To the extent a Voluntary Conversion has only been triggered with respect to a portion of a holder’s Preferred Shares, such holder shall be entitled to trigger the Voluntary Conversion for the remaining part of

23

its Preferred Shares or further fractions thereof, subject to the limitations set forth in the preceding sentence, at any time and repeatedly. After a Voluntary Conversion the respective Preferred Shares for which the Voluntary Conversion has been triggered shall henceforth be deemed Common Shares and the parts of the respective Preferred Shares for which the Voluntary Conversion has not been triggered, if any, shall continue to be deemed Preferred Shares for the purposes of this Agreement.

The number of Common Shares to which a holder of Preferred Shares is entitled upon conversion of Preferred Shares is the product obtained by multiplying, for each series of Preferred Shares being converted, the Conversion Rate applicable for such series of Preferred Stock, as determined in accordance with section 4.6, by the number of Preferred Shares of such series of Preferred Shares being converted.

Upon any Voluntary Conversion of Preferred B Shares, the holder of such Preferred B Shares being converted shall be entitled to any and all declared but unpaid dividends, if any, for such holder’s converted Preferred B Shares, pursuant to section 4.3.

4.5.2 Automatic Conversion

Each Preferred Share will automatically convert into Common Shares based on the then-effective applicable Conversion Rate upon (i) the closing of a Qualified Public Offering or (ii) the consent to such conversion of the holders of at least 60% of the Preferred B Shareholders, or (iii) the consent of the Requisite New Investors to such conversion in connection with any initial public offering, so that all Preference Rights of the Preferred Shares shall automatically be deemed waived and therefore all Preferred Shares forthwith be regarded as Common Shares (the Automatic Conversion).

Upon any Automatic Conversion of Preferred B Shares, the holder of such Preferred B Shares being converted shall be entitled to any and all declared but unpaid dividends, if any, for such holder’s converted Preferred B Shares, pursuant to section 4.3.

4.5.3 Anti-Dilution Adjustment

If prior to or concurrently with a Voluntary Conversion or an Automatic Conversion (each, a Conversion), an Anti-Dilution Event is effected, each holder of Preferred Shares, upon the Conversion of such holder’s Preferred Shares, shall receive additional shareholding in the Company furnished with the same rights and obligations as the Common Shares reflecting the Conversion Rate calculated pursuant to section 4.6. Any such additional shareholding to which the holders of Preferred Shares are entitled shall be satisfied, to the extent possible and permitted by law, by issuing new Common Shares according to the Austrian Act of Capital Adjustment or otherwise by issuing new Common Shares by way of an ordinary

24

share capital increase against payment of EUR 1 (Euro one) for each EUR 1 (Euro one) of the registered share capital increased. Each holder of Preferred Shares receiving new Common Shares pursuant to this section 4.5.3 shall be entitled to receive, in addition to any additional shareholding to which such holder of Preferred Shares is entitled pursuant to this section 4.5.3, that number of new Common Shares equal to the quotient of (a) any amounts paid by such holder of Preferred Shares pursuant to the preceding sentence, divided by (b) the applicable Conversion Rate calculated pursuant to section 4.6. The Parties agree to vote in favor of any such share capital increase, whether (i) pursuant to the Austrian Act of Capital Adjustment or (ii) by way of an ordinary share capital increase, and to waive their subscription right, to the extent they are not entitled to additional shareholding pursuant to this section 4.5. All holders of Common Shares agree to transfer all of the new Preferred Shares received by them (pursuant to Austrian law and the terms of this section 4.5.3, to the existing holders of Preferred Shares without payment and in such proportions that correspond with the number of Preferred Shares held by each holder of Preferred Shares immediately prior to a capital increase according to the terms of this section 4.5.3.

4.5.4 Survival

Notwithstanding anything to the contrary in this Agreement, including section 11, the provisions of sections 4.5 and 4.6 shall survive any termination of this Agreement to the extent required for the Company to register and issue to holders of Preferred Shares all new Common Shares issuable in connection with any conversion of Preferred Shares.

4.5.5 Fractional Shares

No fractional Common Shares shall be issued upon a Conversion of Preferred Shares. All Common Shares (including fractions thereof) issuable upon conversion of the Preferred Shares of a holder shall be aggregated for purposes of determining whether the conversion would result in the issuance of any fractional share. If, after such aggregation, a Conversion would result in the issuance of any fractional Common Share, the Company shall, in lieu of issuing any fractional share, round down the number of Shares issued to such holder to the next full single digit, without paying any compensation.

4.5.6 Pay to Play / Forced Conversion / Preferred B-2 shares

In the event an Investor or such Investor’s Affiliates, including, for the avoidance of doubt, any Blocker Entity (as defined in the Subscription Agreement 3) (a B-2 Non-Funding Investor) fails to subscribe for at least its full portion of Preferred B-2 Shares of the outstanding registered share capital (Grundkapital) of the Company by way of a share capital increase of the Second Tranche pursuant to the terms and

25

conditions of the Subscription Agreement 3 and subject to adjustment as provided therein, the following consequences shall apply:

The B-2 Non-Funding Investor’s Preferred B-1 Shares shall automatically be converted into Common Shares immediately after the closing of the Second Tranche according to the following ratio: one (1) Common Share for six (6) Preferred B-1 Shares, and all declared but unpaid dividends, if any, for such B-2 Non-Funding Investor shall be cancelled, waived and of no further force or effect. Such conversion eliminates any and all Preference Rights provided for in this Shareholders Agreement 2015 and attributed to the Preferred B-1 Shares so converted. Furthermore, each B-2 Non-Funding Investor shall also lose its right to designate a member of the Supervisory Board pursuant to section 5.2.

4.6 Anti-dilution Provision

4.6.1 Conversion Rate

As of the date hereof and for purposes of sections 4.5 and 4.6, both the applicable purchase price and the conversion price for the Preferred Shares are as follows: for the Preferred A Existing Shares and the Preferred A Extension Shares, the Preferred A Purchase Price; for the Preferred B-1 Shares, the Preferred B-1 Purchase Price; and for the Preferred B-2 Shares, the Preferred B-2 Purchase Price. The conversion rates for each series of Preferred Shares (for each series of Preferred Shares, the Conversion Rate) in effect from time to time is equal to the quotient obtained by dividing the applicable purchase price for such series of Preferred Shares by the applicable conversion price for such Preferred Shares as determined pursuant to this section 4.6, such that, as of the date hereof, each Preferred Share is convertible into one Common Share. For the avoidance of doubt, no issuance of Preferred B Shares will be considered an Anti-Dilution Event with respect to the Preferred A Shares.

4.6.2 Anti-Dilution Event

In the event of an issuance by the Company of new Shares, warrants, share equivalents or convertible securities of whatever nature or rights to purchase Shares, warrants, share equivalents or convertible securities of whatever nature (collectively New Securities) after the date hereof for consideration received or receivable by the Company for the issue of each New Security (the New Security Consideration) less than the then-applicable conversion price with respect to the Preferred A Existing Shares, the Preferred A Extension Shares, the Preferred B-1 Shares or the Preferred B-2 Shares, as the case may be (Anti-Dilution Event), then:

(a) if the then-applicable conversion price with respect to the Preferred B-1 Shares or the Preferred B-2 Shares is greater than the New Security Consideration, the conversion price applicable to the Preferred B-1 Shares or the Preferred B-2 Shares with respect to any Voluntary Conversions and/or

26

Automatic Conversions taking place simultaneously or after such Anti-Dilution Event shall be reduced, concurrently with such issue of New Securities, to the New Security Consideration; and

(b) if the then-applicable conversion price with respect to the Preferred A Existing Shares or Preferred A Extension Shares is greater than the New Security Consideration, the conversion price applicable to the Preferred A Existing Shares or Preferred A Extension Shares with respect to any Voluntary Conversions and/or Automatic Conversions taking place simultaneously or after such Anti-Dilution Event shall be calculated on the following broad-based weighted average formula: NCP = CCP x (CSO + DS) / (CSO + NS)).

For the purposes of this section 4.6.2(b):

NCP means the new conversion price for the Preferred A Existing Shares and Preferred A Extension Shares to be determined by the formula;

CCP means the current conversion price for the Preferred A Existing Shares and Preferred A Extension Shares;

CSO means the nominal capital amount in Euro represented by Shares, warrants, share equivalents or convertible securities of whatever nature or rights to purchase Shares, warrants, share equivalents or convertible securities of whatever nature outstanding immediately prior to such Anti-Dilution Event;

DS means the nominal capital amount in Euro represented by the New Securities that would have been issued by the Company in the course of the Anti-Dilution Event had the Anti-Dilution Event been carried out at the Preferred A Purchase Price; and

NS means the nominal capital amount in Euro represented by the New Securities that were actually issued in the course of the Anti-Dilution Event.

If at any time or from time to time on or after the date that the first Preferred B Share is issued, the Company effects a subdivision or combination of its registered share capital, the then-applicable conversion prices for the Preferred Shares will be proportionately decreased or increased, respectively. Any adjustment to the applicable conversion price for the Preferred Shares will also be subject to proportional adjustments for share dividends, recapitalizations or similar corporate events, if any.

Notwithstanding the foregoing, issuance of the following securities by the Company will not be considered an Anti-Dilution Event:

(i) Preferred B Shares;

27

(ii) Common Shares issued or issuable upon the conversion of Preferred Shares;

(iii) Up to 95,000 Common Shares issued pursuant to the Employee Pool as foreseen in section 10.1;

(iv) Shares issued pursuant to the exercise or conversion of convertible securities outstanding as of the date hereof;

(v) Securities that the holders of at least 60% of the outstanding Preferred B Shares elect in writing to exclude from the definition of “New Securities” for the purposes of this section 4.6; and

(vi) Securities issued in the course of an initial public offering, the valuation of which is at least at a fully diluted pre-money valuation (assuming full exercise of all outstanding exercisable securities, rights, options and warrants, including all convertible stock and any shares reserved for issuance under the Employee Pool or similar arrangements) of at least US $ 120,000,000 (USD one-hundred twenty million) with gross proceeds to the Company (before deducting underwriting discounts or commissions and other offering expenses) of not less than US $ 40,000,000 (USD forty million).

a registration statement or pursuant to a Permitted Transfer pursuant to section 6.1(a)) during the 180-day period following the effective date of the initial offering; provided, that all officers and directors of the Company and holders of at least one percent (1%) of the Company’s voting securities are bound by and have entered into similar agreements.

The following Transfers of Shares shall not be subject to the restrictions set out at section 6.1 or sections 6.3 – 6.5 (Permitted Transfers):

(a) a Transfer of Shares, in whole or in part, to (a) an Affiliate, (b) any partner, retired partner or affiliated fund of any Shareholder that is a partnership, or (c) any member or former member of any Shareholder that is a limited liability company, provided, however, that in case of a Transfer to an Affiliate the transfer agreement shall include effective and enforceable provisions, or a separate instrument, obliging and entitling the transferor to reacquire such Shares from the Affiliate if it ceases to be an Affiliate of the transferor;

37

(b) a Transfer of Shares, in whole or in part, made in accordance with the provisions of sections 6.3, 6.4 and 6.5; and

No transfer, including but not limited to the Permitted Transfers, shall be permitted if such Admission Agreement is not timely delivered to the Company.

6.3 Right of First Refusal

6.3.1 Procedure

If, at any time prior to a Qualified Public Offering, a holder of Shares wishes to sell or otherwise transfer (such Shareholder for the purposes of such transaction hereinafter being referred to as Seller) its Shares to another Shareholder or a third party (a Proposed Purchaser), such transfer (Sale) shall be made pursuant to the following procedures:

(a) The Seller shall deliver a written notice (the Offer Notice) to the Company which shall immediately forward a copy thereof to all holders of Preferred Shares. The Offer Notice shall disclose in reasonable detail the Proposed Purchaser, the proposed number of Shares to be sold (Shares To Be Sold) and the proposed terms and conditions (including the proposed price in cash and/or the proposed consideration other than cash). The proposed terms and conditions of the offer must include a provision (pursuant to a resolution of Preferred Shareholders holding 50% or more of the Preferred Shares (determined on the basis as if all Shares would have been converted into Common Shares) and the Requisite New Investors) that the holders of all Preferred Shares shall be entitled to force the Seller and the Proposed Purchaser to consummate the proposed sale of the Share To Be Sold, in case the holders of the Preferred Shares do not exercise their Right of First Refusal.

38

(b) The holders of Preferred Shares shall, pro rata to their shareholdings as opposed to the joint shareholding of all holders of Preferred Shares, be entitled to purchase all of the respective pro rata portion of the Shares To Be Sold specified in the Offer Notice at the price and on the terms specified therein by delivering written notice of such election (the Election Notice) to the Seller within 20 (twenty) days after delivery of the Offer Notice. If not all of the holders of Preferred Shares elect to purchase their respective pro rata portion of the Shares To Be Sold in an Election Notice, the Seller shall re-offer such portion of the Shares To Be Sold for which the Right of First Refusal has not been exercised to such holders of Preferred Shares that have exercised their Right of First Refusal with respect to their respective pro rata portion of the Shares To Be Sold. For this portion of the Shares To Be Sold, the procedure set out in this Subsection (b) shall be re-applied, provided, however, that the final Election Notice shall be delivered to the Seller within 10 (ten) days. Refusal of a holder of Preferred Shares to exercise his Right of First Refusal for such additional portion of the Shares To Be Sold results also in a refusal of the entire Right of First Refusal with respect to such Sale, including with respect to the portion of the Shares To Be Sold in the first offer round.

(c) In case the Right of First Refusal has been validly exercised in accordance with this section 6.3.1, the transfer of the Shares To Be Sold shall be consummated as soon as practicable after the timely delivery of the final Election Notice, but in any event within 14 (fourteen) days after such delivery.

(d) In the event that the Right of First Refusal has not been exercised with respect to the entire Shares To Be Sold, the Seller may, within 90 (ninety) days after delivery of the final Election Notice sell such Shares To Be Sold to the Proposed Purchaser at a price and/or consideration other than cash no more favorable than the price and/or consideration other than cash specified in the Offer Notice and on terms no more favorable to the Proposed Purchaser than specified in the Offer Notice, provided that in the case the Proposed Purchaser is a third party, the Proposed Purchaser agrees in writing to be bound by the provisions of this Agreement with the same rights and obligations as the Seller. Any Shares To Be Sold not sold within such 90-day period shall be re-offered to the holders of Preferred Shares pursuant to this section 6.3.1 prior to any subsequent sale.

Pursuant to Section 1078 of the Austrian Civil Code (Allgemeines Bürgerliches Gesetzbuch), the Parties agree that this Right of First Refusal covers all kinds of transfers of Shares including without limitation by way of barter (e.g., share-for-share transactions, mergers, contributions) or donation. The time limitation set forth

39

in Section 1075 of the Austrian General Civil Code shall be replaced by the provisions of this section 6.3.1. Sections 1075 and 1077 last sentence of the Austrian General Civil Code shall explicitly be excluded.

If as a result of such Sale, the holders of Preferred Shares would remain with an entire stake of less than 50% (fifty percent) of the entire registered share capital of the Company (determined on the basis as if all Shares would have been converted into Common Shares), the Right of First Refusal shall also apply to the holders of Common Shares. In such case, the provisions of this section 6.3 shall apply mutatis mutandis and wherever reference is made to holders of Preferred Shares, such reference shall be to all Shareholders and wherever reference is made to Preferred Shares, such reference shall be to all Shares.

Irrespective of whether the Right of First Refusal expands also to the holders of Common Shares, the Company shall simultaneously with sending such document to the holders of Preferred Shares forward the Offer Notice also to all holders of Common Shares for information purposes.

6.3.2 Purchase Price in Special Cases

If a Sale of Shares occurs (in full or in part) for other consideration than cash, the Parties agree that the price for the respective Shares To Be Sold shall be the market value of such other consideration plus the consideration in cash, if any. In the event the market value cannot be determined or the Seller and (a) Preferred Shareholders holding 50% or more of the Preferred Shares (determined on the basis as if all Shares would have been converted into Common Shares) and (b) the Requisite New Investors do not agree on a value for such consideration, then the market value shall be determined by an independent auditor in a procedure commencing within 14 (fourteen) days after delivery of the Offer Notice. If the Seller and (i) Preferred Shareholders holding 50% or more of the Preferred Shares (determined on the basis as if all Shares would have been converted into Common Shares) and (ii) the Requisite New Investors do not agree on the appointment of such independent auditor within another period of 14 (fourteen) days, the Seller and (y) Preferred Shareholders holding 50% or more of the Preferred B Shares and (z) the Requisite New Investors shall individually be entitled to ask the president of the Austrian Chamber of Accountants (Präsident der Kammer der Wirtschaftstreuhänder Österreichs) to elect an independent auditor with binding effect for both parties. The valuation of such independent auditor shall be binding for the Seller and the holders of Preferred Shares. The costs of such independent auditor shall be borne by the Seller and the holders of Preferred Shares equally, whereby the holders of Preferred Shares amongst themselves bear such costs on a pro rata basis.

40

6.3.3 Insolvency Issues

The Right of First Refusal shall also apply in case of a commencement of insolvency proceedings of whatever sort, not withdrawn or repealed within 30 (thirty) days for other cause than insufficient assets, of any Shareholder. With respect to the purchase price applicable in such scenario, section 6.3.2 applies.

For the avoidance of doubt the terms of this section 6.3 shall not apply in the case of a Permitted Transfer.

6.4 Drag-Along Right

In the event that (i) Preferred Shareholders holding 50% or more of the Preferred Shares (determined on the basis as if all Shares would have been converted into Common Shares) and (ii) the Requisite New Investors (together, the Exiting Sellers) desire to accept an offer from (one or more) third party(ies) to acquire all of the Shares of the Company, such Exiting Sellers shall have the right to force all Shareholders to sell or otherwise transfer all of such shareholders’ Shares to such third party(ies) according to the following procedures.

The Exiting Sellers shall send a written notice (the Drag-Along Notice) to the Company outlining the purchase price and/or the consideration other than cash and the conditions offered by the proposed purchaser(s) for the purchase of all of the Shares of the Company. The Company shall immediately thereafter forward such notice to all other Shareholders. Within 14 (fourteen) days of the receipt of such notice or any later date set forth in such notice, all Shareholders shall sell all their Shares to the respective proposed purchaser according to the terms of the respective offer.

Such Drag-Along Right shall also apply in case of a merger, a sale of assets or any other form of an acquisition of the Company or its assets, which is consented to by (i) the Preferred Shareholders holding 50% or more of the Preferred Shares (determined on the basis as if all Shares would have been converted into Common Shares) and (ii) the Requisite New Investors. In such case all Shareholders shall take whatever action is required to effect the respective transaction, including without limitation voting in favor of a respective shareholders’ resolution.

6.5 Tag-Along Right

In the event a Shareholder (the Obliged Seller) intends to sell or otherwise transfer Shares to a third party or a Shareholder (such sale being a Tag-Along Sale), and provided that the Right of First Refusal has not been exercised pursuant to section 6.3, the Obliged Seller is under the obligation to arrange for those holders of Preferred Shares who wish to do so, to be able to sell or otherwise transfer their pro rata shareholdings to such person(s) under the same terms and conditions. Pro rata

41

means that all holders of Preferred Shares who wish to participate in such Tag-Along Sale may do so in proportion to their respective shareholdings amongst all holders of Preferred Shares and to this extent replace the shares to be sold by the Obliged Seller to the proposed purchaser. The following provisions shall apply to each Tag-Along Sale:

(a) If an Obliged Seller wishes to proceed with a Tag-Along Sale, and the Right of First Refusal according to section 6.3 has not been exercised, it shall deliver a written notice (Tag-Along Rights Notice) to the Company. The Company shall immediately thereafter inform all holders of Preferred Shares of such Tag-Along Rights Notice. The Tag-Along Rights Notice shall disclose in reasonable detail the proposed purchaser, the proposed number of shares to be sold, the proposed terms and conditions of the sale (including the proposed price) as well as a statement by the proposed purchaser that it is offering to all holders of Preferred Shares to purchase their Shares in the pro rata amount set forth above and under the terms and conditions of the sale (including the proposed price) notified in the Tag-Along Rights Notice by the Obliged Seller(s) (the Purchaser’s Offer). Within 14 (fourteen) days of receipt of the Tag-Along Rights Notice, each holder of Preferred Shares may, by written notice to the Company, declare acceptance of the Purchaser’s Offer (partial acceptance shall not be deemed an acceptance, except where the Obliged Seller explicitly agrees) (the Acceptance Notice). In the event that not all other Investors participate in the Tag-Along Sale, the remaining (fraction of) Shares shall be sold by the Obliged Seller(s).

(b) The transfer of the Shares to be Sold and the Shares covered by an accepted Purchaser’s Offer shall be consummated as soon as practical after the delivery of the Acceptance Notice but in any event within 14 (fourteen) days after the delivery of the last Acceptance Notice.

For the avoidance of doubt the terms of this section 6.5 shall not apply in the case of a Permitted Transfer.

(a) information already the public domain;

(b) information getting known through no fault of the disclosee;

10. COVENANTS

10.1 Employee Pool

(a) The Company has established an employee stock option scheme and has reserved for a maximum of 95,000 (ninety five thousand (such number stemming from conditional capital and, to the extent no conditional capital is available, authorized capital and shares to meet the requirements set forth under the stock option scheme)) options of Common Shares (the Employee Pool). Any increase in the size of the Employee Pool shall only be valid if approved in accordance with section 5.4.1(i) of this Agreement.

46

10.3 Tax Status

Notwithstanding any other provision of this Agreement, the Company’s bylaws or the Company’s Articles of Association to the contrary:

(a) The Company shall not engage in a transaction that, to the best of its knowledge after due inquiry with qualified United States tax advisers, is likely to materially increase the U.S. tax liability of a U.S. Holder under Subpart F of the Internal Revenue Code of 1986, as amended (the Code) without that U.S. Holder’s consent.

(b) Not later than the sixty (60) day anniversary following the end of the Company’s taxable year, the Company will provide a capitalization table as of the end of such taxable year to each shareholder and the following information to each New Investor that is not an Initial Investor, including any Blocker Entity affiliated with each such New Investor, if any (each, a U.S. Holder), only: a complete and accurate report, acceptable to at least the majority of the U.S. Holders, regarding the Company’s status as a controlled foreign corporation (a CFC), as defined in section 957of the Code.

(c) If the Company or its tax advisors become aware that the Company is, or if in the reasonable opinion of at least the majority of the U.S. Holders after due inquiry the Company is, a CFC, the Company shall: (1) use reasonable efforts to avoid generating material amounts of income that will be includible in the gross income of a U.S. Holder under Section 951 of the Code, and (2) to the extent permitted by law, pay to each U.S. Holder (whether by way of distribution or otherwise) an amount equal to 50% of the undistributed earnings of the Company that are includible in the gross income of such U.S. Holder (or its Partners) pursuant to Section 951 of the Code, provided, however, that the Company shall not be required to comply with (1) and (2) of this section 10.3(a), if the Company delivers to such U.S. Holder an opinion of a qualified United States tax adviser, in form and substance reasonably acceptable to at least a majority of the U.S. Holders to the effect that the Company is not a CFC. Payment under this section 10.3(a) shall be made to each U.S. Holder entitled thereto not later than sixty (60) days following the end of such U.S. Holder’s taxable year.

(d) The Company shall use commercially reasonable efforts to avoid being a passive foreign investment company (a PFIC), as defined in Section 1297 of the Code. The Company will make due inquiry with its U.S. tax advisors at least annually regarding the Company’s status as a PFIC and if the Company becomes a PFIC, or if there is a likelihood of the Company being a PFIC for any taxable year, the Company shall promptly notify each U.S. Holder of such status or risk, as the case may be. The Company will, as soon as reasonably

47

practicable following the end of each taxable year of the Company (but in no event later than sixty (60) days following the end of each taxable year) provide each U.S. Holder with an accurate and complete PFIC Annual Information Statement in the form set out in Schedule 10.3 and the Company will permit each U.S. Holder and its direct or indirect owners to inspect and copy the Company’s permanent books of account, records and such other Company documents as are necessary to establish that the Company’s ordinary earnings and net capital gain are computed in accordance with U.S. income tax principles.

(e) If any U.S. Holder makes a qualified electing fund election (a QEF Election) pursuant to Section 1295 of the Code with respect to its investment in the Company and such U.S. Holder is required to include an amount in gross income for a particular taxable year pursuant to Section 1293 of the Code, the Company shall, to the extent permitted by law, pay such U.S. Holder (whether by way of a distribution or otherwise) 50% of the amount that such U.S. Holder (or its Partners) is required to include in its gross income as set forth in a properly completed PFIC Annual Information Statement for such year. Payment under this section 10.3(e) shall be made to such US Investor not later than sixty (60) days following the end of the taxable year of such U.S. Holder in which such amount is required to be included in the gross income of such U.S. Holder.

(f) The Company shall not change its characterization as an association taxable as a corporation (for United States tax purposes) without the prior written consent of at least the majority of the U.S. Holders.

(g) If the tax advisors of any U.S. Holder or its Partners reasonably determine that they are subject to U.S. information and reporting requirements that require the disclosure of information about the Company or Company transactions not readily available to such U.S. Holder or its Partners, the Company agrees to provide such information to such U.S. Holder and its Partners as may be necessary to allow such U.S. Holder and its Partners to fulfill their U.S. tax reporting obligations.

(h) The Company will use commercially reasonable efforts to comply in all material respects with all record-keeping, reporting, and other reasonably requests necessary to comply with any applicable U.S. tax law or to allow any U.S. Holder or its Partners to comply with the applicable provisions of U.S. tax law with respect to the direct or indirect ownership of the Company. The Company will provide each U.S. Holder or its Partners with any information available to the Company and reasonably requested to allow such U.S. Holder or its Partners to comply with U.S. tax law with respect to the direct or indirect ownership of the Company.

48

(i) The Company will not withhold any tax against any amounts payable or distributable to any U.S. Holder without first providing notice of such withholding and a reasonable opportunity for such U.S. Holder to obtain reduced rates of withholding or other available exemptions, if any, to the extent such notice and reasonable opportunity for the U.S. holder does not cause the Company to violate any legal requirement to make such withholding or to pay any tax on such payable or distributable amounts.

(j) To the extent any consent, affirmative vote, or other action is required by the Company, its officers or directors, or any of the Company’s shareholders to implement the provisions of this section 10.3, such consent, vote or other action is hereby given or will be given at the applicable time and the Company, its officers and directors, and each of the Company’s shareholders shall fully cooperate in carrying out the provisions of this section 10.3 as required after each closing.

10.4 Survival

Notwithstanding anything to the contrary in this Agreement, including section 11, as to any U.S. Holder, the covenants of the Company in section 10.3(d) and 10.3(i) shall survive for one year following the end of the taxable year of the Company in which such U.S. Holder sells or otherwise disposes of all of its Shares acquired pursuant to Subscription Agreement 3 or acquired or held in the future, and section 10.3(c) and 10.3(e) shall survive until the earlier of (i) a Qualified Public Offering (first day of listing) and (ii) one year following the end of the taxable year of the Company in which such U.S. Holder sells or otherwise disposes of all of its Shares. For the avoidance of doubt, the Company shall be required to make the payments set forth in sections 10.3(c) and 10.3(e) for the portion of the taxable year of the Company that precedes a Qualified Public Offering.

10.5 Anti-Corruption Laws

The Company shall, and shall ensure that any subsidiaries controlled by it, if any, and each of their officers, directors, employees and agents, comply with the U.S. Foreign Corrupt Practices Act (Anti-Corruption Laws). The Company shall establish and maintain an anti-corruption program that is satisfactory to the Supervisory Board [Aufsichtsrat], including the Preferred B Members, pursuant to which the Company will implement and maintain appropriate systems, safeguards, policies, procedures and training sufficient to provide reasonable assurances that the Company, its directors, officers, employees and agents act in compliance with Anti-Corruption Laws. This program shall be implemented within sixty (60) days of the date hereof.

49

10.6 Obligation to give Effect to this Agreement

Each Shareholder shall promptly vote all of his Shares and shall promptly take all other necessary or desirable actions within his control (whether in his capacity as a Shareholder or otherwise, and including, without limitation, attendance at meetings in person or by proxy for purposes of obtaining a quorum and execution of written consents in lieu of meetings and exercise, to the extent permissible by law, his influence over members of the Supervisory Board [Aufsichtsrat]), and the Company shall promptly take all necessary and desirable actions within its control (including, without limitation, calling special board and shareholder meetings) in order to give effect to the provisions of this Agreement.

11. TERM AND TERMINATION

Upon the consummation of a Qualified Public Offering (first day of listing), this Agreement shall automatically terminate (except for those terms that survive as specifically set forth herein).

This Agreement may be terminated by each Party (solely with respect to such terminating Party) by written notice to all other Parties effective as of the end of each calendar year, such written notice to be delivered to all other Parties no less than three (3) months before the end of each calendar year. However, all Parties waive their termination right in such manner that this Agreement may first be terminated with legal effect as per 31 December 2025.
