Subject to the receipt by the Lender
of the duly executed consents of all existing shareholders of the Borrower (the "Shareholders") and all existing holders
of options to acquire shares of the Borrower (the "Option Holders") to this Agreement (as set out in further detail in
Section 13 and in the form of Annex 2) and to the other terms of this Agreement, the Lender hereby grants to the Borrower
a loan (the “Loan”) in the nominal amount of USD 15,000,000.

    6


    Loan Agreement


    

 


		8.	Security



 


The Loan shall not be secured.


 


		9.	Representations and Warranties



 


The Borrower, as per the date of this
Agreement, hereby represents and warrants to the Lender as follows:


 


		a)	the Borrower is a company duly incorporated and validly existing under the laws of Switzerland, and has
full power, authority and legal right to own its assets, to carry on its business as it is being conducted and to enter into and perform
its obligations under this Agreement;



 


		b)	the execution, delivery and performance by the Borrower of this Agreement (i) have been duly authorized
by all necessary corporate decisions and other measures, (ii) require no governmental or regulatory action, authorization or approval,
(iii) do not and will not violate or conflict with the provisions of the articles of incorporation or by-laws of the Borrower and (iv)
do not and will not result in a breach of or constitute a default under any agreement or obligation applicable to the Borrower or by which
the Borrower is bound;



 


		c)	the obligations of the Borrower under this Agreement constitute legal, valid and binding obligations of
the Borrower, enforceable in accordance with their terms; and



 


		d)	no Event of Default has occurred.



 


		10.	Covenants



 


The Borrower hereby covenants and
agrees vis-à-vis the Lender, that it:


 


		a)	unless repaid in whole, shall not use the Loan for the full or partial repayment of the outstanding amount
under the Existing Loan Agreement and/or any other existing or future Financial Indebtedness of the Borrower and/or any future loan agreement
to be entered into by the Borrower with the Existing Lenders and/or any third party;



 






    7


    Loan Agreement


    

 


		b)	shall not grant, create or permit to subsist any security interest, including personal securities (Personalsicherheiten)
such as a surety and guarantee, over any of its present or future assets or revenues, except for security interests arising by operation
of law or in the ordinary course of business;



 


		c)	shall not request the distribution of dividends or other distributions to shareholders (it being understood
that the power to set or not set the dividends lies inalienably with the general meeting of the shareholders); and



 


		d)	shall comply with all material laws and regulations applicable to the Borrower in all material respects.



 


		11.	Status and Subordination



 


Subject to the terms in this Section
11, the claims of the Lender against the Borrower under the Loan shall rank senior to other existing or future unsecured subordinated
obligations of the Borrower (incl. the Existing Loans).


 


The Lender hereby irrevocably and
unconditionally declares to the Borrower that its claims with respect to the Loan owed now or in the future (the “Relevant Subordinated
Claims”), shall be and are hereby subordinated to all current and future claims of creditors of the Borrower.


 


During such term the Relevant Subordinated
Claims shall be deferred (gestundet), the Relevant Subordinated Claims may not be fully or partially be repaid, set-off (but for
a set-off in connection with a capital increase by means by set-off to achieve a Conversion or another debt-to-equity swap (in German:
Verrechnungsliberierung)), novated or otherwise be fulfilled and no security interest may be created in relation to the Relevant
Subordinated Claims. The Relevant Subordinated Claims shall be listed separately in the financial statements of the Borrower. If the Borrower
is declared bankrupt by a court or if the Borrower makes a general assignment, arrangement or composition with or for the benefit of its
creditors, the Lender herewith waive its Relevant Subordinated Claims to the extent required to cover from the liquidation proceeds the
claims of the other creditors and the claims arising in connection with the liquidation procedure.


 


In the case of bankruptcy or debt
restructuring liquidation of the Lender, the Borrower is permitted to offset the Relevant Subordinated Claims of such Lender with the
Borrower’s claims against it.


 


The Lender acknowledges and agrees
that nothing in this Agreement shall be construed as to restrict the board of directors of the Borrower to notify the competent courts
in case of an equity shortfall in the sense of Article 725 para. 2 CO.


 






    8


    Loan Agreement


    

 


The subordination pursuant to this
Agreement shall automatically be terminated if any of the following events occur:


 


		a)	a Conversion is conducted, regardless of an equity shortfall in the sense of Article 725 para. 2 CO;



 


		b)	the Transaction Closing occurs and the Borrower declares in writing (PDF copies of such declaration, duly
executed with wet ink signatures, being sufficient) that after such Transaction Closing, the Borrower is not over indebted pursuant to
Art. 725 para 2 CO and has a positive net equity;



 


		c)	the Borrower declares in writing (PDF copy of such declaration, duly executed with wet ink signatures,
being sufficient) that the subordination be cancelled (aufheben), provided, however, that such cancellation shall only be effective
and binding upon the Parties, if financial statements of the Borrower which (i) are current and reflect the financial conditions of the
Borrower in all material aspects as of the date of the cancellation of the subordination and (ii) audited in accordance with the then
current Swiss Audit Standards (Schweizer Prüfungsstandards) show that all liabilities of the Borrower (including the amounts
owed by the Borrower under the Relevant Subordinated Claims and all other subordinated liabilities, if any) are sufficiently covered by
assets (in case the Borrower is subject to a full audit (ordentliche Revision), a summarizing audit report from the auditor without
a qualification in the sense of Article 725 para. 2 CO suffices to satisfy this requirement);



 


		d)	the Lender irrevocably waives any and all Relevant Subordinated Claims; or



 


		e)	the Borrower declares in writing (PDF copies of such declaration, duly executed with wet ink signatures,
being sufficient) that another creditor of comparable solvency (in German: Bonität) agrees to a subordination of its claims
against the Borrower of least the same amount as the Relevant Subordinated Claims to be released and at the same conditions as applicable
to the Relevant Subordinated Claims and as set forth in this Agreement.



 


The subordination pursuant to this
Agreement has been approved by the board of directors of the Borrower having given due consideration to the creditworthiness of the Lender.
The Lender confirms that sufficient net wealth is at its disposal to absorb a possible or complete loss of the Relevant Subordinated Claims.

    Loan Agreement


    

 


		12.	Conversion



 


		12.1	Voluntary Conversion



 


If the Business Combination Agreement
is terminated pursuant to its Section 11.1 and if prior to the Maturity Date, an Equity Financing Round is consummated, the Lender is
entitled to convert the Loan into Conversion Shares of the Borrower if the Borrower does not repay the Loan before the consummation of
such Equity Financing Round (the "Voluntary Conversion"). For the avoidance of any doubt, the Voluntary Conversion shall
be implemented at the same time and in connection with the Equity Financing Round triggering the Voluntary Conversion.


 


The number of Conversion Shares issuable
upon the Voluntary Conversion shall be determined by dividing the Loan by the applicable Conversion Price.


 


		12.2	Mandatory Conversion



 


If the Business Combination Agreement
is terminated pursuant to its Section 11.1 and if the Loan has neither been repaid within 30 calendar days of the Maturity Date nor a
Voluntary Conversion has taken place, the Loan shall be mandatorily converted into Conversion Shares of the Borrower (the "Mandatory
Conversion" and the Voluntary Conversion, each a "Conversion").


 


The number of Conversion Shares issuable
upon Mandatory Conversion shall be determined by dividing the Loan by the applicable Conversion Price.


 


		12.3	Joint Provisions



 


The Lender hereby undertakes to take
all such actions as may be reasonably necessary or appropriate in order to implement the applicable Conversion, in particular to subscribe
for the respective number of Conversion Shares and to pay the relevant subscription price by setting off the relevant Loan.


 


Prior to the applicable Conversion
being implemented pursuant to this Agreement and as a condition precedent to the obligations of the Borrower under this Section ‎12,
the Lender undertakes to accede to the then current shareholders’ agreement in relation to the Borrower which may contain customary
rights and obligations of shareholders, including, for the avoidance of doubt, rights of first refusal, purchase rights, drag-along rights,
tag-along rights etc.


 






    10


    Loan Agreement


    

 


The Company undertakes and procures,
to the extent legally permissible, that the rights of the Lender under this Section ‎12
are fully honored. The Borrower shall accept the Lender as new shareholder with voting rights and will not claim any restriction on transferability
of shares on the grounds of the articles of association of the Borrower (Statuten). The Borrower undertakes to disclose to the
Lender all information reasonably necessary to ensure that the Lender can ascertain in due course the proper calculation of the Conversion
Price. To the extent required for the implementation of the applicable Conversion, the Borrower shall, in addition to its obligations
under Section 13, use best efforts to procure that the Borrower’s Shareholders take all actions and give all consents required to
allow for the Lender to become a shareholder according to the terms of this Agreement.


 


If the Borrower at any time or from
time to time after the date of this Agreement effects a share split, subdivision or consolidation of Shares, the Conversion Price and/or
other terms of the Conversion shall be adjusted so that the number of Conversion Shares will reflect such effects without detriment to
the Lender.


 


		13.	Shareholder and OPtion holder Consent



 


The Borrower shall obtain consent
in respect of this Agreement from its Shareholders and Option Holders by way of soliciting separate consent declarations as set out in
Annex 2 until February 28, 2022.


 


The Borrower shall obtain consent
in respect of this Agreement by way of soliciting separate consent declarations as set out in Annex 2 from any person that
will be offered to become a shareholder (the "Future Shareholders"), subject to applicable requirements or restrictions
set forth in the Business Combination Agreement and/or the respective implementing agreements in relation to the Transaction, until the
earlier of: (i) the Voluntary Conversion having been consummated, or (ii) the Mandatory Conversion having been consummated.


 


The Borrower shall deliver the PDF
copies of the consent declarations (duly executed by wet ink signatures) of all the Shareholders and all the Option Holders to the Lender
at the latest two business days before the planned disbursement of the Loan.


 


The Borrower shall deliver the PDF
copies of the consent declarations (duly executed by wet ink signatures) of the Future Shareholders two business days before the offer
to become a shareholder can be bindingly accepted by the Future Shareholder.


 






    11


    Loan Agreement


    

 


		14.	Roll-over



 


As part of the closing of the Transaction,
the Lender shall have the right to unilaterally assign and transfer this Agreement with any and all associated rights and claims thereunder
(incl. the claim for full repayment of the Loan) to the Investor in (partial) satisfaction of the Lender PIPE Commitment (the "Roll-Over").


 


In case the Lender chooses to pursue
the Roll-Over and to assign and transfer this Agreement (incl. the claim for full repayment of the Loan to the Investor) in (partial)
satisfaction of the Lender PIPE Commitment:


 


		(i)	the Investor undertakes to accept such assignment and transfer as (partial) satisfaction of the Lender
PIPE Commitment; and

In order to effect the Roll-Over,
each of Lender, Borrower and Investor undertakes to execute and deliver any documents and or to perform any actions required or reasonably
desirable to document and complete the Roll-Over in accordance with this Agreement and applicable law.

full repayment of the Loan) to the Investor as provided for in Section 14 and confirm that if this Agreement (incl. the claim for full

shall also be given for the benefit of the Investor; and

Borrower to effect the conversion of the Loan in accordance with the terms of this Agreement and to waive any priority subscription rights
(Vorwegzeichnungsrechte) and subscription rights (Bezugsrechte) to the extent necessary to allow for the full implementation
of the Voluntary Conversion or the Mandatory Conversion, as applicable.



 


		16.	Sale of Borrower Shares



 


If Business Combination Agreement
is terminated pursuant to its Section 11.1 and if the shareholders of the Borrower decide to sell or are required under the then current
shareholders’ agreement to sell all their respective Shares in the Borrower (the “Exit”), the Lender shall, upon
request of the Company, sell, assign and transfer this Agreement with any and all associated rights and claims thereunder (incl. the claim
for full repayment of the Loan) to the purchaser of such Shares for a consideration equal to the nominal value of the Loan. Each Party
hereby consents in advance to such assignment and transfer.
