Preamble

A.	The Company is organized in the form of a Swiss stock corporation («Aktiengesellschaft») registered with the commercial register of the Canton of Zug under the number CHE-433.093.536.

B.	The Company’s core business is the research, development, manufacturing and marketing of biotechnological, pharmaceutical and similar products in Switzerland and abroad (the «Business»).

The Existing Investors (save for Xxxxx Xxxxxx and the Employees) and the Company have entered into an investment agreement dated 28 April 2021, and each Series A Investor has entered into a share purchase agreement with each Founder or the Company, respectively, dated 28 April 2021 (collectively the «Share Purchase Agreements»), and a shareholders’ agreement dated 28 April 2021 (the «Original Shareholders’ Agreement») in connection with the Series A financing round of the Company. The Company and the Existing Investors have agreed to conduct a second financing round, whereby Helix, a Nasdaq-listed special purpose acquisition company, has entered into a business combination agreement (the «Business Combination Agreement») and an investment and subscription agreement (the «Investment Agreement»), each dated on 4 October 2021, in each case with the Existing Investors and the Company, whereby Helix will subscribe for a number of Voting Shares, each with a nominal value of CHF 0.01, and will subsequently pay a certain remaining investment amount by way of a cash contribution (Kapitalzuschuss) to the Company which will be recorded as “capital contribution reserves” (Kapitaleinlagereserven), and each of Series A Investor 1, 2 and 3, will transfer on the closing of the Business Combination Agreement and the Investment Agreement all its Common Shares to Helix in exchange for Class A Ordinary Shares of Helix (the «BVF Share Transfers»). The transactions contemplated by the Business Combination Agreement and the Investment Agreement are referred to herein as the «Transaction».

The Parties agreed that the Existing Investors holding Common Shares may continue to own Common Shares of the Company after the Transaction has been implemented and shall be granted the right to exchange these Common Shares and Class C Ordinary Shares (the latter will be allocated to Existing Investors holding Common Shares at completion of the Transaction to convey to the Existing Investors voting shares of Helix) into Class A Ordinary Shares in accordance with the provisions of this Agreement. Existing Investors acquiring Common Shares upon exercise of Stock Options after the closing of the Transaction shall be granted the same rights as Existing Investors holding Common Shares at completion. The Parties wish to limit certain statutory shareholders rights of the Existing Investors in the Company as provided herein.

Concurrently with the registration of the Voting Shares in the Commercial Register of the Canton of Zug, Switzerland, as part of the consummation of the Transaction, the Parties execute this Agreement to govern their respective rights and obligations as Shareholders of the Company and provide for the rules governing the operation of the Company.

Promptly following the delivery of the Exchange Notice and in advance of any such Exchange, (i) the Exchanging Holder shall transfer the Exchanged Shares to Helix and (ii) Helix shall transfer to the Exchanging Holder the number of Class A Ordinary Shares and/or the Cash Exchange Payment that the Exchanging Holder is entitled to receive in the Exchange. In addition, on the Exchange Date, the Exchanging Holder shall surrender a number of Class C Ordinary Shares belonging to the Exchanging Holder that is equal to the number of Class A Ordinary Shares that the Exchanging Holder is entitled to receive based on the Exchange Ratio, which such Class C Ordinary Shares shall, on surrender, be automatically cancelled.

Restated and Amended Shareholders’ Agreement – MoonLake Immunotherapeutics AG

Each Common Share that is being transferred by the Exchanging Holder will be exchangeable for a number of Class A Ordinary Shares that is equal to the product of the number of Common Shares being transferred by such Exchanging Holder multiplied by the Exchange Ratio. Each Exchange Notice shall be in the form set forth on Annex 8 and shall include all information required to be included therein.

In addition to any other rights available to the Exchanging Holder and in addition to the obligation of Helix to deliver the Class A Ordinary Shares, if Helix fails to deliver to the Exchanging Holder the Class A Ordinary Shares in accordance with the provisions of this Article 8 on or before the Exchange Date (other than any such failure that is solely due to any action by the Exchanging Holder), and if after such date the Exchanging Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Exchanging Holder’s brokerage firm otherwise purchases, Class A Ordinary Shares to deliver in satisfaction of a sale by the Exchanging Holder of the Class A Ordinary Shares which the Exchanging Holder anticipated receiving upon such exercise (a «Buy-In»), then Helix shall pay in cash to the Exchanging Holder the amount, if any, by which (x) the Exchanging Holder’s total purchase price (including brokerage commissions, if any) for the Class A Ordinary Shares so purchased as required by its broker exceeds (y) the amount obtained by multiplying (1) the number of Class A Ordinary Shares that Helix was required to deliver to the Exchanging Holder in connection with the Exchange by (2) the price at which the sell order giving rise to such purchase obligation was executed. The Exchanging Holder shall provide to Helix (with a copy to the Company) written notice indicating the amounts payable to the Exchanging Holder in respect of the Buy-In and, upon request of Helix, evidence of the amount of such loss. Nothing herein shall limit a Exchanging Holder’s right to pursue any other remedies available to it hereunder, including, without limitation, a decree of specific performance and/or injunctive relief with respect to Helix’s failure to timely deliver Class A Ordinary Shares as required pursuant to the terms hereof.

8.1.2

Optional Cash Exchange by Helix

Within one (1) Trading Day of the delivery by an Exchanging Holder of an Exchange Notice, Helix may elect to settle all or a portion of the Exchange in cash in an amount equal to the Cash Exchange Payment (in lieu of the receipt by the Exchanging Holder of Class A Ordinary Shares) (a «Cash Exchange»), exercisable by giving written notice of such election to the Exchanging Holder within such one (1) Trading Day period (such notice, the «Cash Exchange Notice»). In the event that the settlement of an exchanged Common Share into Class A Ordinary Shares leads to a fraction of such shares in connection with an Exchange, Helix shall either round to the nearest whole share or pay the cash equivalent amount in lieu of any such fractional Class A Ordinary Share. The Cash Exchange Notice shall set forth the portion of the Common Shares subject to the Cash Exchange that will be exchanged for cash in lieu of the receipt by the Exchanging Holder of Class A Ordinary Shares. At any time following the giving of a Cash Exchange Notice and prior to the Exchange Date of the Cash Exchange, Helix may elect (exercisable by giving written notice of such election to the Exchanging Holder) to revoke the Cash Exchange Notice with respect to all of the Exchanged Shares and make the Stock Exchange Payment with respect to any such Exchanged Shares on the Exchange Date.

8.1.3

Change of Control Exchange

Regardless of whether or not the Lock-up Period has expired, in the event of a Change of Control of Helix (a «Helix COC»), Helix may elect, pursuant to a written notice given to the Existing Investors at least thirty (30) days prior to the consummation of the Helix COC (a «COC Notice»), to require each such Existing Investor to exercise Stock Options, if any, and/or to effect an Exchange with respect to all of such Existing Investor’s Common Shares (including any Common Shares received through the exercise of Stock Options), taking into account the conversion of such Existing Investor’s Restricted Common Shares into Common Shares as a result of any such Helix COC (any such exchange, a «COC Exchange») which shall be effective immediately prior to the consummation of the Helix COC (but such Exchange shall be conditioned on the consummation of such Helix COC, and shall not be effective if such Helix COC is not consummated) (the date of such Exchange, the «COC Exchange Date»). In connection with a COC Exchange, such Exchange shall be settled (including, if Helix elects by delivery of a COC Notice, directly by Helix) (x) with the Stock Exchange Payment with respect to the Common Shares subject to the COC Exchange or (y) in cash, so long as in each case each such Exchanging Holder receives the identical consideration, on a per Common Share basis, that the holder of a Class A Ordinary Share would receive in connection with such Helix COC.

8.1.4

Exchange of Restricted Common Shares

To the extent that any Restricted Common Shares are subject to an Exchange Notice and are treated as Exchanged Shares under this Shareholders’ Agreement, then any vesting restrictions under Section 9 that are applicable to such Exchanged Shares shall automatically apply to the Class A Ordinary Shares issued to the Shareholders in the Exchange, irrespective whether this Agreement is terminated for such Exchanging Holder.

8.3

Splits, Distributions and Reclassifications

The Exchange Ratio and/or the components of a Paired Interest shall be adjusted accordingly if there is: (i) any subdivision (by any stock, share or partnership interest split, stock, share or partnership interest distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse stock, consolidation or unit split, reclassification, reorganization, recapitalization or otherwise) of the Class C Ordinary Shares or Common Shares that is not accompanied by a substantially equivalent subdivision or combination of the Class A Ordinary Shares; or (ii) any subdivision (by any stock or share split, stock dividend or distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse stock split, consolidation, reclassification, reorganization, recapitalization or otherwise) of the Class A Ordinary Shares that is not accompanied by a substantially equivalent subdivision or combination of the shares of Class C Ordinary Shares and Common Shares. If there is any subdivision (by any stock, share or partnership interest split, stock, share or partnership interest distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse stock, consolidation or unit split, reclassification, reorganization, recapitalization or otherwise) in which the Class A Ordinary Shares are converted or changed into another security, securities or other property, then upon any subsequent Exchange, an Exchanging Holder shall be entitled to receive the amount of such security, securities or other property that such Exchanging Holder would have received (including as a result of any election by such Shareholder, if afforded to all holders of Class A Ordinary Shares) if such Exchange had occurred immediately prior to the effective date of such reclassification, reorganization, recapitalization or other similar transaction, taking into account any adjustment as a result of any subdivision (by any split, distribution or dividend, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse split, consolidation, reclassification, recapitalization or otherwise) of such security, securities or other property that occurs after the effective time of such reclassification, reorganization, recapitalization or other similar transaction. For the avoidance of doubt, if there is any reclassification, reorganization, recapitalization or other similar transaction in which the shares of Class A Ordinary Shares are converted or changed into another security, securities or other property, this Section 8.3 shall continue to be applicable, with respect to such other security or property. To the fullest extent permitted by applicable law, this Shareholders’ Agreement shall apply to the Paired Interests held by the Shareholders and their permitted transferees as of the date hereof, as well as any Paired Interests hereafter acquired by a Shareholder and his or her or its permitted transferees, subject to Section 4. This Shareholders’ Agreement shall apply to, and all references to “Paired Interests” shall be deemed to include, any security, securities or other property of Helix or the Company which may be issued in respect of, in exchange for or in substitution of shares of Class C Ordinary Shares or Common Shares, as applicable, by reason of any distribution or dividend, split, subdivision, reverse split, consolidation, combination, reclassification, reorganization, recapitalization, merger, exchange (other than an Exchange) or other transaction. This Section 8.3 is intended to preserve the intended economic effect of Section 3 and this Section 8 and to put each Shareholder in the same economic position, to the greatest extent possible, with respect to Exchanges as if such reclassification, reorganization, recapitalization or other similar transaction had not occurred and shall be interpreted in a manner consistent with such intent.

8.4

Helix Covenants

Helix shall at all times keep available, solely for the purpose of issuance upon an Exchange, out of its authorized but unissued Class A Ordinary Shares, such number of Class A Ordinary Shares that shall be issuable upon the Exchange (taking into account the Exchange Ratio) of all outstanding Common Shares (including any Common Shares issued upon exercise of Stock Options as set forth herein) and Restricted Common Shares (other than those Common Shares held by Helix or any Subsidiary of Helix); provided, that nothing contained in this Shareholders’ Agreement shall be construed to preclude Helix from satisfying its obligations with respect to an Exchange by delivery of a Cash Exchange Payment. Helix covenants that all Class A Ordinary Shares that shall be issued upon an Exchange shall, upon issuance thereof, be validly issued, fully paid and non-assessable, free and clear of all liens and encumbrances. In addition, for so long as the Class A Ordinary Shares are listed on a stock exchange or automated or electronic quotation system, Helix shall cause all Class A Ordinary Shares issued upon an Exchange to be listed on such stock exchange or automated or electronic quotation system at the time of such issuance. For purposes of this Section 8.4, references to the “Class A Ordinary Shares” shall be deemed to include any Equity Securities issued or issuable as a result of any reclassification, combination, subdivision or similar transaction of the Class A Ordinary Shares that any Shareholder would be entitled to receive pursuant to Section 8.3.

8.5

Exchange Taxes and Costs

The issuance of Class A Ordinary Shares upon an Exchange shall be made without charge to the Exchanging Holder for any stamp or other similar tax in respect of such issuance; provided, however, that if any such Class A Ordinary Shares are to be issued in a name other than that of the Exchanging Holder (subject to the restrictions in Section 4), then the person or persons in whose name the shares are to be issued shall pay to Helix the amount of any additional tax that may be payable in respect of any transfer involved in such issuance in excess of the amount otherwise due if such shares were issued in the name of the Exchanging Holder or shall establish to the satisfaction of Helix that such additional tax has been paid or is not payable.

Apart from the above, all necessary and required costs and taxes incurred and/or arising in connection with an Exchange, including (but not limited to) security transfer and similar taxes, stock exchange fees, and other transfer related costs shall be borne by Helix (for the avoidance of doubt, other than income taxes), regardless of whether they are incurred by the Exchanging Holder or Helix. For the avoidance of doubt, the BVF Share Transfers do not qualify as an Exchange in the foregoing sense and each of the Parties thereto shall bear its own costs and taxes incurred and/or arising in connection with the BVF Share Transfers.

8.8

Distribution Rights

No Exchange shall impair the right of the Exchanging Holder to receive any distributions payable on the Common Shares redeemed pursuant to such Exchange in respect of a record date that occurs prior to the Exchange Date for such Exchange. No Exchanging Holder, or a person designated by an Exchanging Holder to receive Class A Ordinary Shares, shall be entitled to receive, with respect to such record date, distributions or dividends both on Common Shares redeemed by the Company from such Exchanging Holder and on Class A Ordinary Shares received by such Exchanging Holder, or other Person so designated, if applicable, in such Exchange.

8.9

Tax Matters

Helix, the Company, and any applicable (paying) agent shall be entitled to apply, deduct or withhold taxes to the extent required by applicable Law. Prior to any Exchange, or upon the Company’s reasonable request, each Existing Investor shall deliver to the Company, or its paying agent, if applicable (with a copy to Helix), a duly executed, accurate and properly completed Internal Revenue Service Form W-9 or an appropriate IRS Form W-8, as applicable. If the information on any such form provided by an Existing Investor changes, or upon the Company’s reasonable request, the Existing Investor shall provide the Company with an updated version of such form.

The Parties agree to reasonably cooperate to structure any Exchange in a manner that is tax efficient to the Exchanging Holder.

8.10

Representations and Warranties

In connection with any Exchange, (i) upon the acceptance of the Class A Ordinary Shares or an amount of cash equal to the Cash Exchange Payment, the Exchanging Holder shall represent and warrant that the Exchanging Holder is the owner of the number of Common Shares that the Exchanging Holder is electing to Exchange and that such Common Shares are not subject to any liens or restrictions on transfer (other than restrictions imposed by this Shareholders’ Agreement, the memorandum and articles of association and governing documents of Helix and applicable Law), and (ii) if Helix elects a Stock Exchange Payment, Helix shall represent that (A) the Class A Ordinary Shares issued to the Exchanging Holder in settlement of the Stock Exchange Payment are duly authorized, validly issued, fully paid and non-assessable and were issued in compliance in all material respects with applicable securities laws, and (B) the issuance of such Class A Ordinary Shares issued to the Exchanging Holder in settlement of the Stock Exchange Payment does not conflict with or result in any breach of the organizational documents of Helix.

Reverse Founders’ Vesting

9.1

Vesting Schedule

90% of the Shares held by each of the Founders following the closing of the Share Purchase Agreements (the «Leaver Shares») shall be considered unvested and, therefore, be subject to a reverse vesting and respective call option (the «Leaver Call Options») as further set forth in this Section 9.

The Leaver Shares of each Founder shall (reverse) vest over a period of 2 years as follows (the «Vesting Period»): On the date which is 1 month from the date of the Original Shareholders’ Agreement and, subsequently, each following month until the second anniversary of the closing of the Share Purchase Agreements, 4.166% of the Leaver Shares shall vest, whereas (i) fractions of Shares shall be rounded up to the next full number and (ii) any excess Leaver Shares shall vest on the last vesting instalment.

Upon the occurrence of a Sale, all unvested Leaver Shares shall accelerate (i.e. vest) fully as per the date of the occurrence of the Sale.

9.2

Good Leaver Event

If, before the end of the Vesting Period, the employment relationship of the relevant Founder is terminated and the Founder qualifies as a Good Leaver, all unvested Leaver Shares shall accelerate (i.e. vest) fully as per the date of the end of the employment relationship of the relevant Founder.

9.3

Bad Leaver Event

If, before the end of the Vesting Period, the employment relationship of the relevant Founder is terminated and the Founder qualifies as a Bad Leaver, the Company in first priority (within the limitations of Art. 659 CO and 680 CO) and Helix in second priority, shall have an option to purchase all or a portion of the Leaver Shares that are unvested on the day the termination becomes effective at nominal value.

Restated and Amended Shareholders’ Agreement – MoonLake Immunotherapeutics AG

9.4

Exercise of Leaver Call Options

In the event of a termination of the employment relationship of a Founder, provided such Founder qualifies as a Bad Leaver, the Company shall notify the other Parties within 30 days of the effective date of termination (the «Leaver Notice»).

Each beneficiary (being the Company and Helix) of the Leaver Call Option wishing to exercise their Leaver Call Option shall so notify the Company and the other Parties within 30 calendar days following receipt of the Leaver Notice and state in such notice the number of relevant Shares it intends to purchase («Leaver Call Option Exercise Notice»). Irrespective of the above, the Company may elect that Helix exercises all Leaver Call Option.

The transfer of the relevant Leaver Shares against payment of the purchase price (nominal value) shall be consummated within 60 calendar days from the date of Leaver Call Option Exercise Notice.

Each Founder hereby (i) assigns and transfers to the other relevant Parties (being the Company or Helix), and each such other relevant Party hereby accepts such assignment and transfer, upon and with effect as of the occurrence of a transfer event, in each case, as required to effect a transfer of Shares by such Founder pursuant to this Section 9, (ii) undertakes to procure that the Director(s) nominated by such Shareholder execute their powers and voting rights on the Board so as to ensure that each transfer of Shares in accordance with this Section 9 and only such transfer of Shares be approved by the Board and registered in the Company’s share register, and (iii) undertakes to execute all documents (including, but not limited to, separate assignment declarations) and take all other actions as may be reasonably required to effect each transfer of Shares in accordance with this Section 9.

10.

Accession

Each Shareholder and the Company undertakes to the other Shareholders that no person or entity shall become a Shareholder of the Company or a holder of Stock Options unless and until such person or entity shall first have submitted to the Company an accession declaration satisfactory to the Company pursuant to which such person or entity agrees to be fully bound by and be entitled pursuant to the terms and conditions of this Agreement. The Parties agree that the accession of a third party may take place by unilateral declaration to the Company (representing the Parties); provided, that the conditions stipulated by this Agreement for the acquisition of Shares by the third party have been met or the Stock Option has been exercised in line with its terms. Any party acceding to this Agreement in the foregoing sense or becoming holder of Common Shares pursuant to Sections 7.2(d) and 7.2(f) of this Agreement shall be deemed as from the time of accession an Existing Investor (as defined and used herein) for the purpose of this Agreement with corresponding rights and obligations.

Any accrued rights and obligations of the relevant Party existing at the time of such termination and, for the avoidance of doubt, any restrictions and/or obligations contained in Section 12.2 shall continue to apply to such Party as provided therein.

Any Shareholder that ceases to be a Shareholder of the Company in accordance with the provisions of this Agreement and, for the purpose of the BVF Share Transfers only, the Business Combination Agreement and the Investment Agreement, shall automatically cease to be a Party to this Agreement and shall be released from the provisions hereof; provided, however, that if the Existing Investors could lose their rights under Section 8 of this Agreement as a result of any such Shareholder ceasing to be a Party to this Agreement and being released from the provisions thereof, then such Existing Investors shall be given reasonable advance notice of such event. Such cessation and release shall be without prejudice to any accrued rights and obligations of the relevant Shareholder existing at the time of such cessation and release and, for the avoidance of doubt, any restrictions and/or obligations contained in Section 12.2 shall continue to apply as provided therein.

For Series A Investor 4, the restrictive covenants set forth in Section 6.3.2 and the Helix Call Options set forth in Section 6.4 and any parts of this Agreement referred to therein or relating thereto shall continue to apply for an indefinite period.

In the event of death or bankruptcy of a Party or if a Shareholder otherwise ceases to be a Shareholder, this Agreement shall continue among the remaining Parties (without prejudice to Section 12.3).
