 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»).



 


		C.	The Existing Investors (save for Simon Sturge 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 October
4, 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».



 


		D.	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.



 


		E.	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.



 


Based on the foregoing, the Parties
agree as follows:


 


		1.	Definitions
                                            and Scope



 


Capitalized terms used in this Agreement
shall have the meaning as set forth in Annex 1.

Ratio, which such Class C Ordinary Shares shall, on surrender, be automatically cancelled.



 


		c)	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.

                                                          «Buy-In»), then Helix shall pay in cash to the Exchanging Holder the amount, if any, by which (x) the Exchanging

                                                          required by its broker exceeds (y) the amount obtained by multiplying (1) the number of Class A Ordinary Shares that Helix was

                                                          such purchase obligation was executed. The Exchanging Holder shall provide to Helix (with a copy to the Company) written notice

                                                          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

                                            Cash Exchange by Helix



 


		a)	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.

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.

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.

                                            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

		9.1	Vesting
                                            Schedule

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.


 


		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

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 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.

After expiry of the fixed term pursuant
to Section 11 b) and subject to Section 11 a), this Agreement shall continue to be in effect for successive periods
of 5 years unless terminated by any Shareholder upon 12 months’ prior written notice to all other Parties. Any termination by a
Shareholder shall only be effective with respect to the respective Shareholder, and shall be without prejudice to the continued binding
effect of this Agreement for all other Parties. 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.

A Investor 4 relating to its shareholding in the Company to be exchanged into shares in Helix or legal successor thereof shall not be
deemed such acquisition of Helix securities hereunder and shall remain permitted at all times,



 


		(iii)	acquire,
agree to acquire, or publicly propose or offer to acquire, whether by means of a private or open market purchase, a block trade, a tender
or exchange offer, a merger, consolidation or other form of business combination transaction or in any other manner, (1) beneficial ownership

Agreement) for the purpose of any of the actions described in clauses (i), (ii), (iii), or (iv) above; this paragraph a) including its
subsections the «Standstill Provisions».

investment in any securities of the Company or Helix or any of their Subsidiaries or other Affiliates by or on behalf of any independently
managed pension plan, employee benefit plan or trust, including without limitation (A) any direct or indirect interests in portfolio
securities held by an investment company registered under the Investment Company Act of 1940, as amended, or (B) interests in securities
composing part of a mutual fund or broad based, publicly traded market basket or index of stocks approved for such a plan or trust in
which such plan or trust invests; or (ii) securities of the Company or Helix or any of their Subsidiaries or other Affiliates held by

securities of the Company or Helix, as debtor, that are acquired in a transaction subject to the approval of the competent bankruptcy
court pursuant to proceedings under the applicable bankruptcy legislation in the relevant jurisdiction.

addition, the Standstill Provisions shall automatically terminate and be of no further force and effect with respect to Series A Investor
4, without any action on the part of any Party hereto, at the earlier of (y) December 31, 2024 or (z) if either (i) the Company or Helix
enters into a definitive written agreement with any Person other than Series A Investor 4 (or any of its Affiliates) to consummate a
transaction involving the acquisition of all or a majority of the voting power of the Company’s or Helix’s outstanding equity
securities or all or substantially all of the consolidated assets of the Company or Helix and its consolidated Subsidiaries, other than
in connection with the Business Combination Agreement (whether by merger, consolidation, business combination, tender or exchange offer,
recapitalization, restructuring, sale, equity issuance or otherwise), or (ii) a tender or exchange offer for at least a majority of the
Company’s or Helix’s outstanding equity securities, other than in connection with the Business Combination Agreement, is
commenced by any Person other than Series A Investor 4 or any of its Affiliates and such third-party files a Schedule TO with the United
States Securities and Exchange Commission and (A) Company’s or Helix’s board of directors has recommended in favor of such
offer, or fails to recommend that its stockholders reject such offer within five business days after its commencement or (B) the Company
or Helix has entered into a confidentiality agreement with the tendering Person or an affiliate of the tendering Person. Furthermore,

may be) shall, if consistent with the fiduciary duties of the Company or Helix (as the case may be) as determined by the Company or Helix
(as the case may be), invite Series A Investor 4 to participate in such process at the same time as, and on substantially the same basis
generally applicable to, other participants in such process.



 


Unless otherwise defined herein,
the capitalized terms shall have the meaning as ascribed to them in the Annex 1 (Definitions) of this Agreement.
