________________

The acting Notary Public has drawn the attention of the persons appearing to the fact, that - unless there is a notarial certificate of authenticity of the signatures and a notarial or equivalent confirmation of representation power - he could examine neither the authenticity of the signatures nor the authorisation of the signatories to represent the respective party. Nevertheless the persons appearing insisted on the immediate notarization and released each party from submitting subsequently certified powers of attorney or other documents evidencing or supporting the representative capacity.

The acting Notary advised the persons appearing that a notary who or whose partners in the law firm have formerly acted as legal advisors to one of the parties involved in the matter to be notarized would not be entitled to take office as a notary in the matter at hand pursuant to §§ 23 ss. of the Act of Notarization of the Canton Basel-City, which provisions correspond with the so-called “Vorbefassungsverbot” under the German Act of Notarization (§ 3 Sect. 1(7)). The acting Notary states that he himself and

  9

his firm have not been involved in the matter at hand in the meaning of said provisions. The Parties hereto confirm such statement of the acting Notary.

The persons appearing requested this Deed including its Annexes and Exhibits to be recorded in the English language. The acting Notary Public who is in sufficient command of the English language ascertained that the persons appearing are also in command of the English language. After having been instructed by the acting Notary, the persons appearing waived the right to obtain the assistance of a sworn interpreter and to obtain a certified translation of this Deed including the Annexes and Exhibits hereto.

  21

(2) Each of the Shareholders undertakes individually for himself vis-à-vis each of the other Shareholders, to do or cause to be done everything necessary or appropriate for the implementation of the measures agreed in § 2(1) above.

Thus, each of the Current Shareholders undertakes individually for himself vis-à-vis each of the other Shareholders, in particular without limitation to participate in the Shareholders’ Meeting of the Company as set forth in § 2(1) above, to exercise his voting rights and other rights in such Shareholders’ Meeting in favour of the measures agreed in § 2(1) above, and to waive the subscription rights to which he is entitled for the subscription to new shares to the extent set forth in § 2(1) above.

Further, each of the Shareholders undertakes individually for himself vis-à-vis each of the other Shareholders, to refrain from any actions which could prevent or defer the implementation of the measures agreed in § 2(1) above as well as to waive the right to raise objections to, and to challenge, the resolutions of the Shareholders’ Meeting under § 2(1) above.

(3) Each of the Initial Series C Investors undertakes individually for himself vis-à-vis each other and each of the other Shareholders, but not vis-à-vis the Company, to subscribe and to take over the new Series C Preferred Shares of the Company stated for them in the table in § 2(1)a) above, respectively, immediately after the end of the Shareholders’ Meeting under § 2(1) above and to pay in full and in cash the capital contributions in the nominal value within ten Bank Working Days after this Agreement has come into force to the special account for the increase of the share capital of the Company set forth in § 2(1)a) above. Payments shall be made exclusively to this special account; this special account must not have a debit balance immediately prior to the aforementioned payments being effected, so that the Company’s Managing Directors (Geschäftsführer) can freely dispose of the amounts paid.

(4) Without undue delay (unverzüglich) after (i) the subscription and taking over of the new Series C Preferred Shares under § 2(1)a) above and (ii) the receipt of the total capital contributions in the nominal value for such new shares and (iii) the payment of the additional payments into the capital reserves of the Company by the Initial Series C Investors pursuant to § 4 (for the avoidance of doubt: either directly into the account of the Company or into the trust account set up by the notary as escrow agent), the Company shall apply for registration of the

(5) Should the Commercial Register make valid objections to the increase of the Company’s share capital under § 2(1)a) above and/or the Restated Articles of Association, the Shareholders undertake, as amongst each other, to remove such objections without undue delay by way of adopting the necessary resolutions in the Shareholders’ Meeting of the Company so that the purpose and intention of the provisions objected to can be achieved to the maximum permissible extent.

(6) The Shareholders undertake vis-à-vis each other, as from the notarization of this Agreement up until the increase of the Company’s share capital under § 2(1)a) above and the Restated Articles of Association have been registered with the Commercial Register, to treat each other as if the Restated Articles of Association had already come into force upon the end of the Shareholders’ Meeting under § 2(1)a) above and each of the Initial Series C Investors had already acquired the new Series C Preferred Shares to be issued under § 2(1)a) above upon subscription, respectively, to the extent legally permissible. Thus, each of the Shareholders undertakes individually for himself vis-à-vis each of the Initial Series C Investors, as from the subscription of the new Series C Preferred Shares under § 2(1)a) above, respectively, to put each of the Initial Series C Investors internally in such position as they each would be in, if they had acquired the financial rights (Vermögensrechte) and, to the extent legally permissible, the administrative rights (Verwaltungsrechte) under this Agreement and the Restated Articles of Association resulting from the new Series C Preferred Shares to be issued under § 2(1)a) above upon subscription, respectively.

(7) After the increase of the Company’s share capital under § 2(1)a) above has become effective, the share capital of the Company will be held exclusively by the Shareholders and the Company as follows:

Each of the Second Closing Investors shall render additional payments into the capital reserves of the Company under this § 4 in each case in an amount equal to the investment to which such Second Closing Investor shall be admitted in the Second Closing under § 3(1) above less the aggregate nominal value of the new Series C Preferred Shares of the Company to be subscribed by such Second Closing Investor under § 3(3) above.

(2) The additional payments into the capital reserves of the Company by the Initial Series C Investors under this § 4 shall become due for payment to the Company within ten Bank Working Days after this Agreement has come into force. Each Initial Series C Investor shall be entitled but not obliged to fulfil his respective obligation to render the additional payments into the capital reserves of the

  29

Company under this § 4 by way of payment into a trust account set up by the notary as escrow agent on the basis of the trust agreement between the respective Initial Series C Investor and the notary, provided that the escrow agent shall be obliged under the trust agreement to pay such amount, reduced by fees, charges, costs and/or negative interests incurred by the notary in connection with the trust agreement which shall be deducted by the notary from such amount, to the Company on behalf of the respective Initial Series C Investor within ten Bank Working Days after the registration of the increase of the Company’s share capital under § 2(1)a) above and the Restated Articles of Association under § 2(1)b) above and the filing of the new shareholders list showing the Initial Series C Investors’ shareholding in the Company in accordance with § 2(7) above with the Commercial Register. The obligation to render additional payments of each Initial Series C Investor to the Company’s free capital reserves according to this § 4 shall be deemed fulfilled with the payment of an amount as shown in the table in § 4(1) above into the trust account as set forth in the preceding sentence and any deductions made by the notary (e.g. for costs or negative interests) from such amount when paying it to the Company in accordance with the trust agreement shall not lead to additional payment claims of the other Shareholders under this § 4 vis-à-vis the Initial Series C Investors. The obligations of the notary under such trust agreement shall be undertaken as a true contract for the benefit of third parties (echter Vertrag zugunsten Dritter) in favor of the Shareholders with the effect that each of the Shareholders shall have an own direct claim against the notary to demand that the notary transfers the funds of the respective Initial Series C Investors into the bank account of the Company set forth in § 4(1) above and that the provisions of the trust agreement and in particular the rights of the Shareholders may not be cancelled or modified without the approval of each of the Shareholders.

(3) The Company undertakes not to dispose of the additional payments into the capital reserves of the Company by the Initial Series C Investors under this § 4 in any way until registration of the increase of the Company’s share capital under § 2(1)a) above and the Restated Articles of Association under § 2(1)b) above and the filing of the new shareholders list showing the Initial Series C

  30

Investors’ shareholding in the Company in accordance with § 2(7) above with the Commercial Register. If the registration of the increase of the Company’s share capital under § 2(1)a) above and the Restated Articles of Association under § 2(1)b) above and the filing of the new shareholders list showing the Initial Series C Investors’ shareholding in the Company in accordance with § 2(7) above with the Commercial Register have not occurred by the end of 31 December 2016, or any later date mutually agreed upon between the Parties, the Shareholders shall take best efforts to procure that the additional payments into the capital reserves of the Company under this § 4 shall be repaid to the respective Initial Series C Investor within ten Bank Working Days.

(4) The additional payments into the capital reserves of the Company by the relevant Second Closing Investor under this § 4 shall become due for payment to the Company within ten Bank Working Days after receipt of a notification from the Company in writing, by telefax or e-mail that the relevant increase of the Company’s share capital under § 3(3) above and the corresponding Restated Articles of Association under § 3(4) above have been registered and the new shareholders list showing the relevant Second Closing Investor’s shareholding in the Company resulting from the Second Closing has been filed with the Commercial Register, but by way of a condition precedent only after the passing of the resolutions of the relevant Shareholders’ Meeting under § 3(3) above and the registration of the corresponding Restated Articles of Association under § 3(4) above and the filing of the new shareholders list showing the relevant Second Closing Investor’s shareholding in the Company resulting from the Second Closing with the Commercial Register.

(5) The Shareholders agree that the obligations of the Series C Investors to render additional payments into the capital reserves of the Company under this § 4 shall exist only on the basis of a contractual agreement by and between the Series C Investors and the Shareholders and not vis-à-vis the Company. With exception of the obligation set forth in § 4(3) above, the Company itself is not a party to this § 4 and shall not be entitled to demand the payments under this § 4. The payment claims under this § 4 shall not be assignable. This § 4 shall neither constitute a contract for the benefit of a third party nor a contract with protective effect for the benefits of third parties (kein Vertrag mit Schutzwirkung für Dritte). This § 4 shall not establish any secondary obligations within the meaning of § 3 (2) GmbHG. Any joint and several liability (gesamtschuldnerische Haftung) of the Series C Investors under this § 4 shall be excluded.

Further, except as set forth in § 8 to § 10 of this Agreement and for any claims based on fraud or wilful or gross negligent misconduct which shall remain unaffected, any and all claims and rights of the Series C Investors under and in connection with this Agreement, irrespective of which nature, amount or legal basis, are hereby expressly waived and excluded to the maximum permissible extent, in particular, without limitation, claims under pre-contractual fault (§ 311 (2) and (3) BGB), frustration of contract (Störung der Geschäftsgrundlage), breach of contract (Pflichtver-letzung aus dem Schuldverhaltnis), supplementary performance (Nacherfüllung), the right to reduce the price (Minderung) and/or the right to avoid (Anfechtung) or to rescind (Rücktritt) this Agreement, and any liability in tort (Deliktshaftung).

Without prejudice to (i) the co-sale rights under § 13 below, (ii) the drag-along rights under § 14 below and (iii) the permitted transfers under § 15 below, which shall not be subject to this § 11, the sale, transfer or other disposal of shares of any class of the Company by a Shareholder on or before 21 July 2019 shall require the express prior written consent of Shareholders individually or collectively holding 70 % or more (according to their nominal value) of all issued shares of the Company, voting together as one class, whereby the Shareholder intending to sell, transfer or otherwise dispose of shares of the Company shall be entitled to vote. This shall apply mutatis mutandis to the conclusion, termination, transfer and amendment of sub-participations and trust agreements as well as the pledging or encumbrance of shares of any class of the Company by a Shareholder on or before 21 July 2019.

§ 12
Rights of First Refusal

(1) If any of the Shareholders (hereinafter referred to as the “Selling Shareholder”) intends to transfer (including by way of a swap or contribution) his shares of any class of the Company in whole or in part with or without consideration to another Shareholder or a third party (hereinafter referred to as the “Potential Purchaser”), then he is under an obligation to inform all Shareholders and the Company of such intent without undue delay and in writing, by telefax or e-mail (hereinafter referred to as “Text Form”, and such information to all Shareholders and the Company hereinafter referred to as the “Notification”). The Notification shall include in particular the name/firm and address/registered office of the Selling Shareholder and the Potential Purchaser, the number/nominal value and class of the shares of the Company intended to be transferred, the purchase price or other consideration and the due date for payment together with any representations, warranties, indemnities and other claims to be given or declared by the Selling Shareholder and the Potential Purchaser as well as the remedies available in case of a breach thereof. In the event that non-monetary consideration is provided for, the Selling Shareholder shall state the equivalent monetary value of such non-monetary consideration for the purposes of the rights of first refusal set forth below. The value of non-monetary consideration shall be determined in accordance with the respective consideration’s fair market value. The Advisory Board of the Company, by way of simple majority resolution, shall instruct an independent expert (e.g. an auditor) acting as arbitration expert to submit a report and make a determination on the fair market value of such consideration unless otherwise agreed by the relevant parties. The costs incurred as a result of instructing such expert shall be borne by the Selling Shareholder. The results of such report and determination shall be final and binding on all Parties with respect to the fair market value of the consideration payable for the purposes of the rights of first refusal set forth below.

(2) If any of the Shareholders intends to transfer (including by way of a swap or contribution) his shares of any class of the Company in whole or in part with or without consideration to another Shareholder or a third party, all Shareholders other than the Selling Shareholder (hereinafter collectively referred to as the “Other Shareholders” and each individually as an “Other Shareholder”) shall have a right of first refusal as set forth in the following provisions to acquire the

  43

shares of the Company which the Selling Shareholder intends to transfer, at the terms and conditions set forth in the Notification as possibly amended by the determination of the fair market value of non-monetary consideration by the independent expert under § 12(1) above. Within four (4) weeks after the later of (i) the receipt by the respective Other Shareholder of the Notification and (ii) the delivery of the report by the independent expert under § 12(1) above, if any, (hereinafter referred to as the “Exercise Period”) each Other Shareholder shall state in writing to the Company whether he is willing to acquire that portion of the shares of each class of the Company which the Selling Shareholder intends to transfer, which corresponds to the total nominal value of all shares of the Company held by the respective Other Shareholder in proportion to the total nominal value of all shares of the Company held by all Other Shareholders inter se, in whole or in part in accordance with this § 12 (hereinafter referred to as the “Purchase Statement”). The Purchase Statement shall be binding in accordance with the following provisions. After the expiry of the Exercise Period for all Other Shareholders, the Company shall inform all Shareholders without undue delay and in Text Form of the aggregate number/nominal value of the shares of each class of the Company for which the rights of first refusal under this § 12(2) have been exercised and by whom (hereinafter referred to as the “Exercise Statement”).

(3) If not all Other Shareholders have exercised their right of first refusal under § 12(2) above in whole, the Other Shareholders who have exercised their right of first refusal under § 12(2) above in whole (hereinafter collectively referred to as the “Exercising Shareholders” and each individually as an “Exercising Shareholder”) shall have an extended right of first refusal as set forth in the following provisions to acquire the remaining shares of the Company which the Selling Shareholder intends to transfer and for which the rights of first refusal under § 12(2) above have not been exercised, at the terms and conditions set forth in the Notification as possibly amended by the determination of the fair market value of non-monetary consideration by the independent expert under § 12(1) above. Within two (2) weeks after the receipt by the respective Other Shareholder of the Exercise Statement (hereinafter referred to as the “Extended Exercise Period”) each Exercising Shareholder shall state in writing to the Company the maximum number/nominal value of shares of each class of the Company for which the rights of first refusal under § 12(2) above have not been exercised and which such Exercising Shareholder is willing to additionally acquire

  44

(hereinafter referred to as the “Acquisition Limit”) in accordance with this § 12 (hereinafter referred to as the “Extended Purchase Statement”). The Extended Purchase Statement shall be binding in accordance with the following provisions. After the expiry of the Extended Exercise Period for all Exercising Shareholders, the Company shall inform all Shareholders without undue delay and in Text Form of the aggregate number/nominal value of the shares of each class of the Company for which the extended rights of first refusal under this § 12(3) have been exercised and by whom (hereinafter referred to as the “Extended Exercise Statement”).

(4) If the aggregate Acquisition Limits for all classes of shares of the Company are equal to or exceed the aggregate number/nominal value of the shares of the respective class of the Company for which the rights of first refusal under § 12(2) above have not been exercised, the Other Shareholders who have issued a Purchase Statement shall be entitled and obliged to acquire from the Selling Shareholder the shares of the Company which the Selling Shareholder intends to transfer pursuant to the Notification in accordance with the following provisions: All Other Shareholders who have issued a Purchase Statement shall be entitled and obliged to acquire from the Selling Shareholder that portion of the shares of each class of the Company which the Selling Shareholder intends to transfer pursuant to the Notification in accordance with their respective Purchase Statement, and in addition the Exercising Shareholders who have issued an Extended Purchase Statement shall be entitled and obliged to acquire from the Selling Shareholder the remaining shares of each class of the Company which the Selling Shareholder intends to transfer pursuant to the Notification and for which the rights of first refusal under § 12(2) above have not been exercised, each of these Exercising Shareholders limited to such Exercising Shareholder’s Acquisition Limit, and up to such Acquisition Limit with respect to each class of shares of the Company pro rata to the nominal value of all shares of the Company held by such Exercising Shareholders inter se unless such Exercising Shareholders agree otherwise. Indivisible fractional amounts shall be purchased by the Other Shareholder who issued his Purchase Statement or Extended Purchase Statement, as applicable, first; whereby the relevant time shall be the receipt of the Purchase Statement or Extended Purchase Statement, as applicable, by the Company. The Selling Shareholder as well as the Other Shareholders who are entitled and obliged to acquire from the Selling Shareholder the shares of the Company which the Selling Shareholder intends to transfer pursuant to the

  45

Notification under the preceding sentences shall without undue delay and in any event within two (2) weeks after the receipt of the Extended Exercise Statement enter into a notarized share sale and transfer agreement in accordance with the terms and conditions set forth in the Notification as possibly amended by the determination of the fair market value of non-monetary consideration by the independent expert under § 12(1) above, the respective Purchase Statement and, if applicable, Extended Purchase Statement and the allocation of shares of the Company pursuant to this § 12(4). For the avoidance of doubt, such share sale and transfer agreement shall only be entered into if the necessary consent under § 11 above has been given.

(5) If the aggregate Acquisition Limits for any class of shares of the Company fall short of the aggregate number/nominal value of the shares of such class of the Company for which the rights of first refusal under § 12(2) above have not been exercised, no rights of first refusal shall apply at all. In such event, the Selling Shareholder, subject to the co-sale rights pursuant to § 13 below, and the other Shareholders, who exercise such co-sale rights, shall be entitled to transfer their shares of the Company to the Potential Purchaser, but only in strict compliance with the terms and conditions stated in the Notification (as possibly amended by the determination of the fair market value of non-monetary consideration by the independent expert under § 12(1) above) as well as the provisions of § 16(1) and § 17 below, during a period of two months after the receipt of the Extended Exercise Statement. A notarized certified copy of the contract concluded between the Selling Shareholder and the other Shareholders, if applicable, on the one hand and the Potential Purchaser on the other hand shall be submitted for review to all other Shareholders. For the avoidance of doubt, such a transfer shall not be permitted, unless the necessary consent under § 11 above has been given.

§ 13
Co-sale Rights

(1) All Shareholders shall be entitled to demand from a Selling Shareholder, who has made a Notification and under § 12(5) above is entitled to transfer shares of the Company to the Potential Purchaser, the co-sale of the shares of the Company held by the respective Shareholder in accordance with the terms and conditions set forth in the Notification as possibly amended by the determination of the fair

  46

market value of non-monetary consideration by the independent expert under § 12(1) above, to the extent desired by the respective Shareholder. Such co-sale right is to be exercised by way of written declaration, such declaration setting forth the maximum (and, if desired, minimum) number/nominal value and class of the shares of the Company the respective Shareholder wishes to be co-sold. The said notification is to be submitted to the Company within four (4) weeks after the later of (i) the receipt by the respective Shareholder of the Notification and (ii) the delivery of the report by the independent expert under § 12(1) above, if any, and may be made jointly with the issuance of a Purchase Statement pursuant to § 12(2) above. In the Exercise Statement, the Company shall inform all Shareholders about the extent and content of all requests for the co-sale of shares of the Company that have been made within said four-weeks-period.

(2) If the Potential Purchaser is not willing to purchase the shares of the Company from the Selling Shareholder and the shares of the Company the co-sale of which is demanded pursuant to § 13(1) above, save for the provision set forth in § 13(4) below, the Selling Shareholder is obliged, upon request of the respective Shareholders who have exercised their co-sale right, to transfer his own shares of the Company and the shares of the Company the co-sale of which has been demanded pro rata to the nominal value of the shares of the Company held by the Selling Shareholder and such Shareholders who have exercised their co-sale right inter se unless such Shareholders demand the co-sale of all their shares of the Company in accordance with the following provisions.

(3) Before transferring and after having received the notification that rights of co-sale have been exercised, the Selling Shareholder is obliged to inform the Shareholders who have exercised their co-sale right of the total number/nominal value of shares of the Company that the Potential Purchaser wishes to acquire. If the Potential Purchaser does not wish to acquire all the shares of the Company that the Shareholders who have exercised their co-sale right demand to be included in the sale, the Shareholders exercising their co-sale right must inform the Selling Shareholder within two weeks after receipt of the notification under the preceding sentence, whether they request to sell their shares of the Company on a pro rata basis according to § 13(2) above or all their shares of the Company pursuant to § 13(4) below; such request shall be binding on the Selling Shareholder.

  47

(4) In the event that the Potential Purchaser is a competitor of the Company or a company affiliated with a competitor of the Company within the meaning of §§ 15 et seq. of the German Stock Corporation Act (AktG), the co-sale right may be exercised with respect to all of the shares of the Company held by the respective Shareholder, irrespective of the class, and the transfer by the Selling Shareholder to the Potential Purchaser shall only be permitted if the Potential Purchaser takes all shares of the Company of a Shareholder who has exercised his co-sale right and requests the co-sale of all his shares of the Company. Sentence 1 shall also apply in the event that the Potential Purchaser, even if not a competitor of the Company or a company affiliated with a competitor of the Company, would hold, directly and/or indirectly, 50 % or more of the share capital of the Company after the acquisition of the shares of the Company from the Selling Shareholder and from the Shareholders who have exercised their co-sale right on a pro rata basis under § 13(2) above. The preceding provisions shall also apply when the Potential Purchaser is already a minority shareholder of the Company and would, after the acquisition of the shares of the Company from the Selling Shareholder and from the Shareholders who have exercised their co-sale right on a pro rata basis under § 13(2) above, hold, directly and/or indirectly, 50 % or more of the share capital of the Company. If the terms of the transaction(s) which trigger the right of the other Shareholders to co-sell their shares of the Company are, without any justified reason, less favourable than the terms of earlier transactions with the Potential Purchaser, the terms of the earlier transactions, and if there have been several earlier transactions, the weighted average, shall apply to the co-sale right of the other Shareholders. For the purposes of the preceding provisions, shares of the Company already held and/or to be acquired in connection with such acquisition by a company affiliated with the Potential Purchaser or a person acting in concert with the Potential Purchaser shall be deemed to be held by the Potential Purchaser. For the purpose of this provision, a “competitor” is a firm, body corporate or person which offers a similar product, whether marketed, commercialized or under development, or service as the Company at the time of the relevant transfer (i.e. drug development, drug marketing and commercialization or manufacturing in the field of acute and chronic inflammatory diseases). For the avoidance of doubt, the Parties acknowledge that neither Staidson (Beijing) Biopharmaceutical Company Limited nor Staidson shall be deemed to be a competitor of the Company.

  48

(5) All terms and conditions for the transfer of shares of the Company in compliance with this § 13 shall equal the terms and conditions which apply to the transfer of shares of the Company by the Selling Shareholder.

§ 14
Drag-along Rights

(1) In the event that Shareholders individually or collectively holding 70 % or more (according to their nominal value) of all issued shares of the Company, voting together as one class, (hereinafter referred to as the “Drag-along Majority”) consent at any time and from time to time to (i) the disposal of all shares of the Company (also by way of a swap, contribution or merger), (ii) the disposal (including by way of exclusive license(s)) of all or substantially all of the tangible and intangible assets of the Company (calculated at fair market values and irrespective of whether such assets may be shown in the Company’s financial statements under applicable generally accepted accounting principles) (also by way of a swap, contribution or merger) or (iii) a transformation of the Company within the meaning of § 1 of the German Act on Transformations of Companies (UmwG) except for a conversion (formwechselnde Umwandlung), then any and all Shareholders shall be obliged to dispose of all their shares of the Company or to participate in the asset deal or transformation on the same (pro rata) terms and conditions in accordance with the following provisions of this § 14.

(2) In the event that a draft contract meets all of the following requirements, the Drag-along Majority shall be entitled to demand from any and all Shareholders that they enter into the contract with the acquirer or submit a corresponding firm offer to the prospective acquirer within five calendar days of the receipt of the draft contract:

a) the Drag-along Majority agrees to the draft contract including the related terms and conditions;

b) all shares of the Company or all or substantially all of the tangible and intangible assets of the Company (calculated at fair market values and irrespective of whether such assets may be shown in the Company’s financial statements under applicable generally accepted accounting principles) shall be included in the transaction;

  49

c) the acquirer’s consideration shall be in cash and/or in a divisible consideration in kind (e.g. shares) and shall be distributed among the Shareholders in accordance with § 21 below;

d) the consideration distributed to each Shareholder in accordance with § 21 below shall be in cash and/or in a divisible and liquid consideration in kind (e.g. publicly traded shares) to the extent required to timely pay any and all taxes and other charges accruing to the respective Shareholder as a result of the transaction; and

e) the liability of each Shareholder for representations, warranties, indemnities and other claims granted to the acquirer in connection with the transaction shall be limited at most to the proceeds of such Shareholder; moreover, none of the Shareholders shall be obliged to grant any representations, warranties, guarantees or indemnities other than with respect to the title in, and third party rights regarding, the shares of the Company sold by the respective Shareholder and their respective capacity to enter into the contract.

(3) Each of the Shareholders shall, according to the terms and conditions agreed upon by the Drag-along Majority, without undue delay submit all declarations and take all measures which the implementation of the transaction under § 14(1) above requires, in particular without limitation pass shareholders’ resolutions (in particular without limitation under § 13 (3) of the Restated Articles of Association) or apply for required court or administrative orders.

(4) In the event that the prospective acquirer (i) is an Affiliate of a Shareholder or (ii) acts commercially for the account of a Shareholder, such Shareholder shall not be entitled to participate in any decision with respect to a transaction under § 14(1) above and the Drag-along Majority shall be calculated on the basis of the remaining shares of the Company excluding the shares of the Company held by such Shareholder.

(5) § 11, § 12, § 13 and § 16(1) of this Agreement shall not apply to any transaction under this § 14. This § 14 shall take precedence over § 13 (3) of the Restated Articles of Association.

  50

AktG, without § 11, § 12 and § 13 of this Agreement being applicable to such transfers; provided, however, that in the event that such transferee ceases to be affiliated with the transferring Financial Investor within the meaning of §§ 15 et seq. AktG, it shall transfer the shares of the Company back to the transferring Financial Investor or another person, entity or firm which is affiliated with the transferring Financial Investor within the meaning of §§ 15 et seq. AktG. This shall apply mutatis mutandis to transfers of shares, which the Financial Investors carry out in favour of other funds, partnerships, investment vehicles or other entities (whether corporate or otherwise) whose business is managed by the transferring Financial Investor or a person, entity or firm affiliated with the transferring Financial Investor within the meaning of §§ 15 et seq. AktG or a general partner or managing limited partner or management company of the transferring Financial Investor.

The persons, funds, partnerships, investment vehicles, entities and firms named under the 1^st and 2^nd sentence of this § 15(1), in each case excluding portfolio companies of the respective Investor, are hereinafter collectively referred to as the “Affiliates” and each individually as an “Affiliate”.

(2) ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇▇▇ and Romaria may at any time and from time to time transfer their respective participations in the Company held by them in whole or in part to each other, without § 11, § 12 and § 13 of this Agreement being applicable to such transfers.

§ 16
Accession of Future Shareholders to this Agreement

(1) The Parties agree that each future shareholder of the Company, including shareholders acquiring shares under § 15 above, may and must accede as a party to this Agreement prior to or concurrently with the acquisition of shares of the Company, with the rights and obligations which correspond to those of his respective legal predecessor. Each of the Shareholders shall be entitled and obliged to transfer his rights and obligations under this Agreement together with the shares of the Company to which such rights and obligations relate, provided that such transfer of shares of the Company occurs in accordance with the provisions of this Agreement and the Restated Articles of Association. Each of the Parties hereby declares his consent, and hereby offers, to such acquirers of shares of the Company to so accede as a party to this Agreement and to such transferring Shareholder to so cease to be a party to this Agreement, provided that such transfer of shares of the Company occurs in accordance with the provisions of this Agreement and the Restated Articles of Association. Each of the Parties, with the exception of the Company, waives the requirement that they are notified of such accession and leaving pursuant to § 151 sentence 1 BGB (Verzicht auf den Zugang der Beitritts- and Austrittserklärung gemäß § 151 Satz 1 BGB), which shall become effective upon receipt by the Company of a corresponding instrument duly executed in notarized form by the transferring Shareholder and the acquirer of shares of the Company.

(2) The Parties agree that each acquirer of shares of the Company under the ESOP may and must accede as a party to this Agreement prior to or concurrently with the acquisition of shares of the Company under the ESOP, with the rights and obligations of a Shareholder, a Party and a holder of Common Shares of the

  52

Company. § 16(1) sentences 3 and 4 above shall apply mutatis mutandis. The Parties further agree that in the event that the relevant stock options are exercised in connection with a transaction as a result of which the co-sale right may be exercised with respect to all of the shares of the Company held by the respective Shareholder pursuant to § 13(4) above, an IPO (as defined below), or a transaction triggering the distribution of the Proceeds in accordance with § 21 below (hereinafter referred to as a “Trade Sale”), then upon exercise of the stock options, the holders of stock options shall be treated as if they had been Shareholders, Parties and holders of Common Shares already immediately prior to such transaction, e.g. they shall be so entitled to co-sale rights under § 13 above, shall be so subject to the drag-along right under § 14 above and shall be so subject to and included in the distribution of the Proceeds in accordance with § 21 below.

(3) Pursuant to the German Prevention of Money Laundering Act (Geldwäschegesetz) (hereinafter referred to as “GWG”), KfW is obliged to identify the shareholders of the Company and – as the case may be – possible legal successors of such shareholders and any party that accedes to this Agreement. In order to fulfil the requirements imposed by the GWG, the Shareholders and – as the case may be – possible legal successors of such Shareholders and any party that accedes to this Agreement hereby undertake vis-à-vis KfW, to provide KfW with a copy of their passports (individual person) or an excerpt form the competent commercial register including a list of shareholders (legal entity) and – insofar as existent – to identify the beneficial owner of such Shareholder. The Shareholders undertake to provide KfW with the aforementioned documents until the date of accession of each such Shareholder as a party to this Agreement. For the avoidance of doubt, such Shareholder whose documents are required shall only refer to a Second Closing Investor or any future investors of the Company and shall not include any Current Shareholders nor the Initial Series C Investors.

§ 17
Consent of the Shareholders

If a Shareholder wishing to transfer has, prior to or concurrently with the disposal of his shares of the Company, complied with the provisions of § 11 to § 16 above, then the Shareholders shall be obliged to declare their consent pursuant to § 15 (1) of the Restated Articles of Association to the disposal of shares of the Company by the

  53

respective Shareholder, irrespective of whether or not they have exercised any rights of first refusal or co-sale rights to which they may be entitled.

§ 18
Inheritance

(1) In the event of the death of one of the Shareholders, the rights and obligations under this Agreement shall devolve on his heirs. The heirs must evidence their title by the presentation of an inheritance certificate or official evidence of inheritance in accordance with § 35 of the German Land Register Act (GBO). If the shares of the Company of the deceased are inherited by joint co-heirs (Erbengemeinschaft), they are under an obligation to exercise their rights under this Agreement and the Articles of Association of the Company jointly and to determine a joint representative for these purposes in writing to the Company. So long as a joint representative has not been appointed or the proof of inheritance has not been given, all rights under this Agreement and as a shareholder of the Company shall be suspended (except for the right to participate in profits) to the extent legally permitted.

(2) In the event of the gift of shares of the Company by means of a legacy, the testator and the heirs shall make the transfer of the shares of the Company dependent upon the beneficiary of the legacy becoming a party to this Agreement; § 16(1), § 17 and § 18(1) above shall apply mutatis mutandis.

Section IV
Further Financing of the Company

§ 19
Future Financing Agreements

(1) Each of the Shareholders undertakes individually for himself vis-à-vis each other Shareholder, but not vis-à-vis the Company, to enter into investment agreements and shareholders’ agreements and related agreements (replacing or amending this Agreement and/or any successor agreements and/or the Articles of Association of the Company and/or other related agreements), to pass resolutions in Shareholders’ Meetings of the Company (in particular without limitation under § 13 (3) of the Restated Articles of Association), and to do or cause to be done everything necessary or appropriate, for further rounds of financing of the

  54

Company (hereinafter collectively referred to as the “Future Financing Agreements”), to the extent that Shareholders individually or collectively holding 90 % or more (according to their nominal value) of all issued shares of the Company, voting together as one class, agree to the terms and conditions of the Future Financing Agreements; provided, however, that (i) to the extent that the Future Financing Agreements provide for an obligation of Shareholders to make further contributions to the Company, the Future Financing Agreements shall require the consent of the Shareholders affected, and (ii) to the extent that the terms and conditions of the Future Financing Agreements materially diminish or adversely affect the rights of any Shareholder in a manner disproportionately unfavourable to such Shareholder as compared to similar situated Shareholders, the Future Financing Agreements shall require the consent of such disproportionately and unfavourably affected Shareholder with regard to the application of such terms and conditions specifically to it. § 2(2) to (6) above shall apply mutatis mutandis. This § 19 shall in particular without limitation include the obligation to implement (i) the financial terms and conditions of such further rounds of financing, in particular without limitation the valuation, the amount and rank of the liquidation and trade sale preferences and the stock exchange demand rights, (ii) the extension of existing rights and obligations under this Agreement and/or the Restated Articles of Association to new shareholders of the Company joining under the Future Financing Agreements, (iii) changes to majorities under this Agreement and/or the Restated Articles of Association (including, but not limited to, the Drag-along Majority), (iv) changes to rights to appoint and remove members of the Advisory Board of the Company, and this § 19 shall also include the obligation to waive rights under this Agreement and/or the Restated Articles of Association (e.g. liquidation and trade sale preferences, veto rights, consent requirements, and rights to appoint and remove members of the Advisory Board of the Company), in each case provided that Shareholders individually or collectively holding 90 % or more (according to their nominal value) of all issued shares of the Company, voting together as one class, agree. The right of the Shareholders to invest in further rounds of financing of the Company on a pro rata basis shall remain unaffected.

(2) Notwithstanding the undertaking set forth in § 19(1) above, KfW shall in its reasonable discretion be entitled to reject any Future Financing Agreement if (i) the conclusion of such Future Financing Agreement would in the reasonable view of KfW result in the breach of any regulations applicable for KfW or which are the

  55

basis for the participation of KfW in the Company, in particular the KfW Participation Principles as set forth in § 26(1) below or (ii) to the extent that the terms and conditions of the Future Financing Agreements diminish or adversely affect the rights of KfW. For the avoidance of doubt: If KfW rejects a Future Financing Agreement under this § 19(2), the majority set forth in § 19(1) above shall not be entitled to demand the participation of KfW within such Future Financing Agreement; in particular, KfW shall not be obliged to make any investment within such Future Financing Agreement.

Section V
IPO and Trade Sale

§ 20
Initial Public Offering

(1) The Drag-along Majority is entitled to demand from the Company and any and all Shareholders the direct or indirect (via a holding company) listing of the Company and/or the Company’s shares and/or the public offering of the Company’s shares or a secondary offering of the Company’s shares on a qualified stock exchange within the European Union or Switzerland, a transnational stock exchange, the New York Stock Exchange or the NASDAQ (hereinafter referred to as an “IPO”); provided, however, that all Shareholders hereby agree that the Management Board with the consent of the Advisory Board may initiate at any time an IPO on the NASDAQ or Euronext without any further approval or resolution of the Shareholders or the Drag-along Majority.

(2) The Drag-along Majority has the right to demand a successful IPO under § 20(1) above twice; the Drag-along Majority is furthermore entitled to demand a successful IPO on two different stock exchanges named in § 20(1) above. The Parties agree that (i) any stock exchange listing which is not demanded by the Drag-along Majority or initiated by the Management Board with the consent of the Advisory Board under § 20(1) above and (ii) the selection of the stock exchange and the exchange segment where the Company’s shares shall be listed other than the NASDAQ or Euronext shall require the prior consent of the Drag-along Majority. The selection of the consortium banks and the conclusion of agreements with the consortium banks shall in any event require the prior consent of the Advisory Board.

In the event that the Proceeds are paid in tranches and/or contingent upon conditions and/or deferred and/or paid into an escrow account (in particular without limitation to cover any representations, warranties, indemnities or similar

In the event that not all shares of the Company are included in the Trade Sale, then with respect to any subsequent sale, share swap or contribution of shares of the Company or other transaction with respect to shares not included in such initial Trade Sale, the provisions of this § 21(1) shall apply accordingly in respect of the allocation of the total consideration to the Shareholders for such subsequent sale, share swap, contribution or other transaction (irrespective of the percentage of the share capital of the Company included in such subsequent transaction).

In the event of more than one Trade Sale and/or subsequent sale, share swap or contribution of shares of the Company or other transaction under the preceding sub-paragraph, the respective preference payment under § 21(1)a)aa) to cc) above, respectively, shall be paid only until the respective holder of the respective class of Preferred Shares has, together with any preceding preference payments under § 21(1)a)aa) to cc) above, respectively, in aggregate received the full amount of the respective preference payment set forth in § 21(1)a)aa) to cc) above, respectively.

(3) In the event of a share swap, contribution, merger or other transformation within the meaning of § 1 UmwG other than a conversion, the Shareholders agree vis-à-vis each other, but not vis-à-vis the Company, that the consideration shall be distributed according to § 21(1) above, when as a consequence of such transaction the Shareholders hold less than 50 % of the receiving or surviving legal entity. The preference on the Proceeds pursuant to § 21(1) above shall be fulfilled in such case by way of a transfer of shares before the carrying out of such measures (compensation in advance/Vorabausgleich). To the extent that the consideration in kind consists of shares in companies listed on a stock exchange, the share price fixed at the stock exchange at the time and date that the transfer of the consideration takes effect shall be conclusive; in all other cases, the fair market value of such consideration in kind at the time and date of the consummation of the relevant transaction shall be decisive, which shall be determined with binding effect on all Shareholders by the Company’s auditor in accordance with the IDW-guidelines for the purposes of applying § 21(1) above mutatis mutandis. When as a consequence of the transactions mentioned in sentence 1 above the Shareholders hold 50 % or more of the receiving or surviving legal entity, the Shareholders agree vis-à-vis each other, but not vis-à-vis the Company, that the rights of the Shareholders under this Agreement and the Restated Articles of Association must continue to exist in full and unchanged; otherwise, sentences 1 to 3 above shall apply accordingly.
