		13.3.	Delivery

 

		(a)	Any communication or document made or delivered by one person
to another under or in connection with the Notes Documents will only be effective:

 

		(i)	if by way of letter, unless actually received earlier by the
addressee, on the fifth (5th) Business Day (provided that a copy of the notice has also been sent by email on the date of dispatch);

		13.4.	Electronic communication

		14.	OTHER
EQUITY-LINKED FINANCING

 

As long as any Notes are outstanding,
the Issuer and any of its Subsidiaries or Affiliates shall not drawdown any variable rate equity financings currently in place or participate
in any new variable rate equity financings. For the avoidance of doubt, this does not apply to the currently existing agreements with
Nice & Green SA and the Yorkville SEDA. To the extent that the Issuer has, under any variable rate equity financing already drawn-down,
the right to repay the counterparty in cash instead of Issuer Shares, the Issuer hereby undertakes towards the Investor to repay the counterparty
in cash, except for the balance of Convertible Notes outstanding under the first agreement with Alpha Blue Ocean (a total of CHF 160,000)
which may be repaid in shares. For the avoidance of doubt, the Issuer confirms that the Issuer has the right to repay in cash any draw-downs
under the equity-linked investment with Alpha Blue Ocean announced on 7 May 2021.

 

		15.	NEGATIVE PLEDGE

 

Following the Initial Notes Tranche
Closing Date and as long as Notes are outstanding, the Issuer shall not grant or create, in connection with any Financial Indebtedness,
any mortgage, lien, pledge, charge or any other security interest or encumbrance of any kind on any asset of the Issuer in connection
with the financing of any acquisition of a target that has revenues of less than US$ 5m (LTM). For the avoidance of doubt, this does not
limit the Issuer from (i) restructuring a secured financing arrangement to the extent no new or other security or additional collateral
is granted in connection with the restructuring or (ii) granting liens on personal property which is purchased from a creditor.

 

		16.	RIGHT OF FIRST REFUSAL ON FINANCINGS

 

Following the signing of this
Agreement until the later of (i) 12 months following the signing of this Agreement and (ii) as long as any Note is outstanding, the Investor
shall have a first right of refusal on any equity and/or debt financings the Company intends to obtain. The Investor shall exercise such
right of first refusal within 3 Trading Days of the receipt of a notice from the Issuer setting forth all details required for the Investor
to make a decision with respect to the exercise of the right of first refusal. For the avoidance of doubt, this also applies to any potential
drawdown under the Yorkville SEDA facility.

 

     

     

    

 

		17.	PARTIAL INVALIDITY

 

If,
at any time, any provision of a Notes Document is or becomes illegal, invalid or unenforceable in any respect under any law of any jurisdiction,
neither the legality, validity or enforceability of the remaining provisions nor the legality, validity or enforceability of such provision
under the law of any other jurisdiction will in any way be affected or impaired.

 

		18.	REMEDIES AND WAIVERS

 

No failure to exercise, nor any
delay in exercising, on the part of the Investor, any right or remedy under a Notes Document shall operate as a waiver of any such right
or remedy or constitute an election to affirm any Notes Document. No election to affirm any Notes Document on the part of the Investor
shall be effective unless it is in writing. No single or partial exercise of any right or remedy shall prevent any further or other exercise
or the exercise of any other right or remedy. The rights and remedies provided in each Notes Document are cumulative and not exclusive
of any rights or remedies provided by law.

 

		19.	AMENDMENTS AND WAIVERS

 

Any term of the Notes Documents
(including this Clause) may be amended or waived only with the consent of the Investor and the Issuer.

 

		20.	ASSIGNMENTS AND TRANSFERS

 

		(a)	The Investor may assign and transfer all or any of its rights,
benefits and obligations under this Agreement to any of its Affiliates or its successors. Prior to the occurrence of an Event of Default,
such assignments and transfers (as well as exposure transfers) will be permissible only as long as the Swiss Non-Bank Rules are respected.

 

		(b)	Except for any transfer pursuant to paragraph (a) of this Clause
20 and further provided that these assignments or transfers are to a Swiss Qualifying Bank, no Party shall be entitled to assign and
transfer all or any of its rights, benefits and obligations under this Agreement without the other Parties' prior written consent, provided
that the Investor shall not be required to obtain the Issuer's consent in connection with the grant of any security (including any charge
or assignment, by way of security) over any of the Investor's rights under this Agreement in favour of any of its lenders or other persons
providing to that Investor any loan or other financing arrangement for the Investor's subscription of all or a portion of the Notes to
be subscribed by it pursuant to this Agreement, provided such grant of security does not lead to a violation of the Swiss Non-Bank Rules.
For the avoidance of doubt, it shall not be reasonable for the Issuer to withhold its consent as long as there are not more than five
lenders that are not Swiss Qualifying Banks in aggregate under this Agreement.

 

		(c)	For the avoidance of doubt, this Clause 20 shall not apply to the transfer by the
Investor of any Notes, which transfers are solely governed by the Conditions.

 

		21.	NON-DISCLOSURE OF NON-PUBLIC INFORMATION

 

The Issuer covenants and agrees
that it shall refrain from disclosing, and shall cause its officers, directors, employees, advisors and agents to refrain from disclosing,
any material non-public information to the Investor without also disseminating such information to the public.

 

		22.	ENTIRE AGREEMENT

 

This Agreement (including the Schedules
hereto and the documents and instruments referred to in this Agreement that are to be delivered pursuant to this Agreement) constitutes
the entire agreement among the Parties and supersedes any prior understandings, agreements or representations by or among the Parties,
or any of them, written or oral, with respect to the subject matter of this Agreement.

 

     

     

    

 

		23.	COUNTERPARTS AND CONCLUSION OF CONTRACT

 

		(a)	This Agreement may be executed in any number of counterparts,
and this has the same effect as if the signatures on the counterparts were on a single copy of this Agreement.

 

		(b)	This Agreement may be concluded by an exchange of signed signature
pages, transmitted by way of fax or attached as an electronic photocopy (.pdf, .tif, etc.) to email.

 

		24.	GOVERNING LAW AND JURISDICTION

 

		24.1.	Governing law

 

This Agreement is governed by the laws of Switzerland.

 

		24.2.	Jurisdiction

Party agrees that any legal action arising out of or relating to this Agreement, including actions relating to disputes on the
conclusion, validity or amendment of this Agreement, must be brought exclusively before the competent courts of the City of Zurich,
Switzerland (venue being Zurich 1).

continue to accrue at a rate which is 2.5 per cent. higher than the Cash Interest Rate (both before and after judgment) until the day
on which all sums due in respect of that Note up to that day are received by or on behalf of that Noteholder.

 

		(c)	Deduction of Swiss Withholding Tax: Should a
deduction of Swiss Withholding Tax be required by law to be made by the Issuer in respect of any interest payable by it under this Agreement
and should it be unlawful for the Issuer to comply with Condition 11 (Taxation) for any reason (where this would otherwise be
required by the terms of Condition 11 (Taxation)), (A) the applicable interest rate in relation to that interest payment shall
be the interest rate which would have applied to that interest payment (as provided for in Condition 6 (Interest)) in the absence
of this paragraph (c), divided by (ii) 1 minus the rate at which the relevant Swiss Withholding Tax deduction is required to be made
(where the rate at which the relevant tax deduction is required to be made is for this purpose expressed as a fraction of one (1) rather
than as a percentage), and (B) (i) the Issuer shall be obliged to pay the relevant interest at the adjusted rate in accordance with this
paragraph (c). Each relevant Noteholder shall promptly co-operate in completing any procedural formalities to possible reclaim the Swiss
Withholding Tax deducted. If and to the extent a Noteholder receives a refund of Swiss Withholding Tax, it shall forward such amount,
after deduction of costs, to the Issuer, unless an Event of Default is continuing. Nothing in this paragraph shall interfere with the
Noteholder's right to arrange its tax affairs in whatever manner it thinks fit and, without limiting the foregoing, no Noteholder shall
be under any obligation to claim any Swiss Withholding Tax refund in priority to any other claims, relieves, credits or deductions available
to it.

 

		7.	PAYMENTS

 

		(a)	Payment of Principal and Interest: Payment of
principal, interest (after deduction of the then applicable Swiss Withholding Tax: see Condition 11 (Taxation)) and any other
payments in cash to be made under these Conditions will be made available (unless a contrary indication appears in a Notes Document)
for value on the due date at the time and in such funds specified by the relevant Noteholder as being customary at the time for settlement
of transactions in dollars in the place of payment.

 

		(b)	The Issuer undertakes that payments shall be made in freely
disposable funds as specified by the relevant Noteholder as being customary at the time for settlement of transactions in dollars in
the place of payment without collection cost to the Noteholders, and, unless otherwise provided for by applicable law, without any restrictions
and whatever the circumstances may be, irrespective of nationality, residence or domicile of the Noteholders and without requiring any
affidavit or the fulfilment of any other formality, except for the fulfilment of the requirement set out in paragraph (c) below.

 

		(c)	Delay in Payment: Noteholders shall not be entitled
to any interest or other payment in respect of any delay in payment resulting from the due date for payment not being a Business Day.

 

		8.	CONVERSION RIGHTS

 

		(a)	Conversion Rights: Subject to the other provisions
of this Condition 8, each Note shall entitle the holder thereof to convert the Principal Amount of that Note plus interest accrued thereon
(calculated on the basis of the Cash Interest Rate) until the Conversion Date (the "Conversion Amount") to be settled
by converting the Conversion Amount into Issuer Shares at the Conversion Ratio as determined in accordance with Condition 8(b) (Conversion
Ratio and Conversion Price), credited as fully paid. Each such right of a Noteholder to require a conversion of the Conversion Amount
into Issuer Shares at the Conversion Ratio is herein referred to as the "Conversion Right" and together the "Conversion
Rights" and the settlement of the Conversion Amount via the conversion of such amount into Issuer Shares at the Conversion Ratio
is herein referred to as a "Conversion".

 

     

     

    

 

		(b)	Conversion Ratio and Conversion Price: The conversion
ratio (the "Conversion Ratio") will be determined by converting the Conversion Amount into CHF, using the Noteholder's
Rate of Exchange on the Conversion Date and dividing the resulting figure by the Conversion Price prevailing on the Conversion Date.
Any remainder smaller than CHF 10 shall not be paid.

 

		(c)	Conversion Price B Conversions: Notwithstanding
anything to the contrary set out in Condition 8(b) (Conversion Ratio and Conversion Price), the Noteholder shall have the right
to:

 

		(i)	convert each calendar month a Conversion Amount of up to 12.5%
of the initial aggregate principal amount of all issued Tranches into Issuer Shares whereby the Conversion Ratio will be determined by
converting the Conversion Amount into CHF, using the Noteholder's Rate of Exchange on the Conversion Date and dividing the resulting
figure by the Conversion Price B. Any remainder smaller than CHF 10 shall not be paid. For the avoidance of doubt, the receipt of a Redemption
Notice shall in no way restrict the Noteholder from exercising the conversion right according to this Condition 8(c)(i) as long as the
Notes have not been cancelled in accordance with Condition 10(c). The Issuer shall, in its sole discretion, have the right to waive the
limit of 12.5%. For the avoidance of doubt, the Investor can convert more than the 12.5% if the daily VWAP is above the Fixed Conversion
Price.

 

		(ii)	convert, upon occurrence of an Event of Default, a Conversion
Amount equalling the sum of the aggregate principal amount of all issued and unconverted Notes, accrued interest and premium (if any)
and the Make-whole Amount (if applicable) into Issuer Shares whereby the Conversion Ratio will be determined by converting the Conversion
Amount into CHF, using the Noteholder's Rate of Exchange on the Conversion Date and dividing the resulting figure by the Conversion Price
B. The number of Issuer Shares to be delivered upon Conversion shall be rounded down to the next full number. Any remainder smaller than
CHF 10 shall not be paid.

 

		(iii)	convert, upon receipt of a Redemption Notice, a Conversion Amount
of up to 12.5% of the initial aggregate principal amount of all issued Tranches into Issuer Shares whereby the Conversion Ratio
will be determined by converting the Conversion Amount into CHF, using the Noteholder's Rate of Exchange on the Conversion Date and dividing
the resulting figure by the Conversion Price B. Any remainder smaller than CHF 10 shall not be paid. For the avoidance of doubt, the conversion
right according to this Condition 8(c)(iii) may be exercised in addition to the conversion right according to Condition 8(c)(i). The Issuer
shall, in its sole discretion, have the right to waive the limit of 12.5%.

 

		(d)	Conversion Notices: A Noteholder may exercise
its Conversion Rights at any time during the term of the relevant Note (the "Exercise Period") by serving a Conversion
Notice to the Issuer whereupon the Issuer shall procure the issue or transfer and delivery to, or as directed by, that Noteholder of
Issuer Shares credited as fully paid in accordance with Condition 8(i) (Delivery of Issuer Shares). If the Conversion Notice is
delivered after the end of normal business hours in Zurich, Switzerland, or on a day which is not a Business Day, such delivery shall
be deemed for all purposes of this Conditions to have been made on the following Business Day.

 

		(e)	Conversion at Maturity: It is understood and
agreed that the Investor is obliged to request Conversion of each Convertible Note held by the Investor prior to the Maturity Date except
in case an Event of Default has occurred and the Investor hence irrevocably undertakes to request Conversion of all outstanding Convertible
Notes prior to the Maturity Date. To the extent the Investor has failed to request Conversion prior to the date falling ten (10) Business
Days prior to the Maturity Date, the Issuer shall be authorized to request Conversion on behalf of the Investor during the last ten (10)
Business Days immediately prior to the Maturity Date. Such Conversion shall be made through the Issuer (or any person designated by the
Issuer) completing a Conversion Notice on behalf of the Investor. A copy of such Conversion Notice shall immediately be sent to the Investor.
The Conversion will take place at the lower of the Fixed Conversion Price and Conversion Price B.

 

		(f)	Exercise of Conversion Right: The Conversion Right may
be exercised at any time during the Exercise Period in one or multiple instances and with respect to any Conversion Amount, provided
that each conversion represents a round whole number of Notes exceeding 1 (i.e. the "minimum" Conversion Amount is USD 100,000
and Conversion Amounts must be in multiples of USD 100,000) and the maximum single Conversion Amount is USD 2,500,000 (unless such limit
to the maximum single Conversion Amount is waived by the Issuer), always provided that such maximum single Conversion Amount shall not
apply to Conversion Price B Conversions according to section 8(c) (Conversion Price B Conversions). Upon the exercise of the Conversion
Right by the relevant Noteholder, the respective Conversion Amount shall be deemed to become immediately due and payable and upon delivery
of the relevant number of Issuer Shares, the respective Conversion Amount shall be deemed to be settled.

 

		(g)	Conversion Date: The conversion date in respect of a
Conversion Amount (the "Conversion Date") shall be the date on which a Conversion Notice has been received or is deemed to
have been received in accordance with Condition 8(d) (Conversion Notices).

 

		(h)	Conversion Limitation: Notwithstanding anything to the
contrary set out in this Condition 8 (Conversion Rights), no Conversion may take place if as a result of such Conversion the relevant
Noteholder would beneficially own in excess of 9.99% per cent. of the outstanding share capital of the Issuer (as computed pursuant to
Rule 13d-3 promulgated under the U.S. Securities and Exchange Act of 1934)(the "Conversion Limitation"). If as of the time
of Maturity the Noteholder exceeds the Conversion Limitation or the Noteholder may be deemed an "affiliate" of the Company,
the Note shall be extended, at the election of the Investor, at a maximum 3 times for a period of 2 months each (i.e. maximum 6 months
in total) prior to the conversion according to Section 8(e)(Conversion at Maturity). The word "affiliate" shall be defined
as provided in Rule 501(b) under the Securities Act of 1933

 

     

     

    

 

		(i)	Delivery of Issuer Shares:

 

		(i)	Issuance of Issuer Shares: The Issuer Shares to be delivered
upon the exercise by a Noteholder of a Conversion Right pursuant to this Condition 8 shall be delivered from Issuer Shares held in treasury
by the Issuer or its Subsidiaries or newly issued from the Issuer's conditional share capital (bedingtes Aktienkapital) or the
Issuer's authorized share capital (genehmigtes Aktienkapital), with the same entitlements as the other outstanding Issuer Shares,
except that the Issuer Shares so delivered will not give any right for any dividend or other distribution declared, paid or made by reference
to a Record Date prior to the Conversion Date and except that the voting rights may not be exercised unless the person designated in
the Conversion Notice as recipient of the Issuer Shares is registered as the holder of the Issuer Shares in the Issuer's share register
(Aktienbuch).

 

		(ii)	Delivery of Issuer Shares: The Issuer will use best
efforts to effect delivery of the Issuer Shares within not more than one (1) Trading Day after the Conversion Date; in any event, the
Issuer will effect delivery of the Issuer Shares within not more than two (2) Trading Days after the Conversion Date through the Intermediary
in accordance with directions given by the Noteholder in the relevant Conversion Notice and enter the Noteholder (or any designee of
the Noteholder to which relevant Issuer Shares are transferred in accordance with the Conversion Notice) into the Issuer's share register
(Aktienbuch). For the avoidance of doubt, it is acknowledged that the first Delivery of Issuer Shares may take up to five (5)
Trading Days, subject to the compliance requirements of the Issuer and the Investor's respective custodian banks and any verification
checks that they are required to carry out. As long as the Issuer undertakes its best efforts to effect delivery of the Issuer Shares,
this will not be considered an Inability to issue Conversion Shares pursuant to the immediately following paragraph.

 

		(iii)	Inability to issue Conversion Shares: If the Issuer
is unable to deliver the Issuer Shares to the Investor within two Trading Days after the Conversion Date in compliance with this Agreement
for any reason, then without limiting any other rights of the Investor under this Agreement, the Investor may (but is not required to)
either: (a) both (i) hold over the Conversion Price that would have applied to the Conversion (the "Applicable Price");
and (ii) once the Company's inability to deliver the Issuer Shares is overcome, apply the Applicable Price to determine the number
of Issuer Shares that are then issuable and require such number of Issuer Shares to be delivered by the Issuer; or (b) require the Issuer
to repay the Alternative Amount (instead of issuing the Issuer Shares). The Alternative Amount, in relation to any delivery of Issuer
Shares, means (yy) 103% of the Conversion Amount that would have otherwise been the subject of the delivery of Issuer Shares if delivery
is made within less than 5 Trading Days and (zz) 108% of the Conversion Amount that would have otherwise been the subject of the delivery
of Issuer Shares if delivery is made on the 5th Trading Day or later. For the avoidance of doubt, this section shall not apply in case
the inability to deliver the Conversion Shares is solely the Investor's fault for not instructing its share agent properly.

 

		(iv)	Taxes and other costs. Any Swiss Federal Stamp Duty,
if due, as well as the fee of the Relevant Exchange, if any, payable upon the delivery of the Issuer Shares to the Noteholder (or any
designee of the Noteholder) upon a Conversion will be paid or reimbursed by the Issuer.

 

		9.	NOMINAL VALUE MAKE-WHOLE

 

At the Noteholder's discretion,
if the Conversion Price B on the relevant Conversion Date is lower than the nominal value of the Shares, the Noteholder shall accept to
receive a number of Shares equal to the Conversion Amount divided by the nominal value of the Issuer Shares, provided that the relevant
Noteholder also receives a cash contractual penalty payment of an amount equal to the closing price of the Issuer Share on the Conversion
Date multiplied by the difference between (i) the Conversion Amount divided by the applicable Theoretical Conversion Price and (ii) the
Conversion Amount divided by the nominal value of the Issuer Shares (the "Nominal Value Make-Whole Payment").

 

     

     

    

 

		10.	REDEMPTION AND PURCHASE

 

		(a)	Redemption at the Option of the Issuer: If the
Voluntary Prepayment Requirement is met, the Issuer may, by giving not less than 15 Business Days' (or such shorter notice the relevant
Noteholder may agree) prior notice to the Noteholders in accordance with Condition 14 (Notices) (which notice shall be irrevocable
and shall specify the date fixed for redemption) (the "Redemption Notice"), redeem the Notes at their Principal Amount
together with accrued and unpaid interest to (and including) the day of redemption and together with the Make-whole Amount pertaining
to each Note. For the avoidance of doubt, upon receipt of the Redemption Notice until actual Redemption, the Investor has the right to
convert the amount to be redeemed according to the Redemption Notice at the applicable Fixed Conversion Price.

 

		(b)	No other redemption: The Issuer shall not be
entitled to redeem the Notes otherwise than as provided in Condition 9(a) (Redemption at the Option of the Issuer).

 

		(c)	Cancellation of Notes: All Notes which are redeemed
or converted pursuant to Condition 8 (Conversion Rights) and this Condition 9 (Redemption and Purchase) will be cancelled
and may not be reissued or resold.

 

		11.	TAXATION

 

All payments of principal and interest
in respect of the Notes shall be made free and clear of, and without withholding or deduction for, any Taxes imposed, levied, collected,
withheld or assessed by or on behalf of any relevant jurisdiction, unless such withholding or deduction is required by law. In that event,
the Issuer shall pay such additional amounts as will result in the receipt by the Noteholder of such amounts as would have been received
by them if no such withholding or deduction had been required.

 

		12.	PRESCRIPTION

 

Claims for payment of the Principal
Amount or interest cease to be enforceable by legal action in accordance with the applicable Swiss statute of limitations (presently after
10 years in case of claims for payment of the Principal Amount and after five years in case of claims of payment of interest, in each
case from the relevant due date for payment).

 

     

     

    

 

		13.	EVENTS OF DEFAULT

 

L1 Capital Global Opportunities
Master Fund (in its capacity as initial Noteholders' Representative) or any other person appointed by the Majority Noteholders as Noteholders'
Representative in its place (the "Noteholders' Representative") has the right but not the obligation to notify the Issuer
in writing (such notice, an "Acceleration Notice") that the Notes are, and shall thereupon immediately become, due and

date any amount (including, without limitation, principal, premium or interest payable), in each case in respect of the Notes at the

		(B)	a Disruption Event; and

 

		(ii)	payment is made within three (3) Business Days of its due date.

 

		(b)	Breach of the Share Coverage Covenant: If, at

any Notes equal to 150% of the outstanding aggregate principal amount converted into CHF using the Noteholder's Rate of Exchange divided
by the applicable Conversion Price B, and the Issuer has not rectified this within a period of 20 Trading Days following the initial
breach, then this is considered a Breach of the Share Coverage Covenant.

 

		(c)	Failure to deliver Issuer Shares upon Conversion: The

Notice, the right to serve such Acceleration Notice shall revert to the Noteholders' Representative whereby the Noteholders'
Representative shall not be bound by the resolution of the Noteholders' meeting if and to the extent that new circumstances arise or
become known which require a new assessment of the facts.

		15.	AMENDMENTS TO THESE CONDITIONS

 

These Conditions may be amended
by agreement between the Issuer and the Noteholders' Representative (acting in its capacity as such) on behalf of the Noteholders provided

prejudicial to the interests of the Noteholders. Notice of any such amendment shall be published in accordance with Condition 14 (Notices).

or any substitute address or
email address or department or officer as any Party may communicate to the other Party by not less than five (5) Business Days' notice.

 

		13.3	Delivery

 

		(a)	Any communication or document made or delivered by one person to another under
or in connection with the Notes Documents will only be effective:

 

		(i)	if by way of letter, unless actually received earlier by the addressee, on the
fifth (5th) Business Day (provided that a copy of the notice has also been sent by e- mail on the date of dispatch); or

will be effective only when actually received by the Investor or the Issuer and then only if it is expressly marked for the attention
of the department or officer identified in Clause 13.2 (Addresses) (or any substitute department or officer as the Investor shall

		(c)	Any communication or document which becomes effective, in accordance with paragraphs(a)
and (b) above, after 9:00 p.m. in the place of receipt shall be deemed only to become effective on the following day.

 

		13.4	Electronic communication

and information made between them as well as between them and their external advisers and consultants may be made by encrypted or unencrypted

		14.	OTHER EQUITY-LINKED FINANCING

 

As long as any Notes are outstanding,
the Issuer and any of its Subsidiaries or Affiliates shall not drawdown any variable rate equity financings currently in place or participate
in any new variable rate equity financings. For the avoidance of doubt, this does not apply to the currently existing agreements with
Nice & Green SA and the Yorkville SEDA. To the extent that the Issuer has, under any variable rate equity financing already drawn-down,
the right to repay the counterparty in cash instead of Issuer Shares, the Issuer hereby undertakes towards the Investor to repay the counterparty
in cash, except for the balance of Convertible Notes outstanding under the first agreement with Alpha Blue Ocean (a total of CHF 160,000)
which may be repaid in shares. For the avoidance of doubt, the Issuer confirms that the Issuer has the right to repay in cash any draw-downs
under the equity-linked investment with Alpha Blue Ocean announced on 7 May 20211.

 

		15.	NEGATIVE PLEDGE

 

Following the Initial Notes
Tranche Closing Date and as long as Notes are outstanding, the Issuer shall not grant or create, in connection with any Financial Indebtedness,
any mortgage, lien, pledge, charge or any other security interest or encumbrance of any kind on any asset of the Issuer in connection
with the financing of any acquisition of a target that has revenues of less than US$ 5m (LTM). For the avoidance of doubt, this does not
limit the Issuer from (i) restructuring a secured financing arrangement to the extent no new or other security or additional collateral
is granted in connection with the restructuring or (ii) granting liens on personal property which is purchased from a creditor.

 

		16.	RIGHT OF FIRST REFUSAL ON FINANCINGS

 

Following the signing of this
Agreement until the later of (i) 12 months following the signing of this Agreement and (ii) as long as any Note is outstanding, the Investor
shall have a first right of refusal on any equity and/or debt financings the Company intends to obtain. The Investor shall exercise such
right of first refusal within 3 Trading Days of the receipt of a notice from the Issuer setting forth all details required for the Investor
to make a decision with respect to the exercise of the right of first refusal. For the avoidance of doubt, this also applies to any potential
drawdown under the Yorkville SEDA facility.

 

		17.	PARTIAL INVALIDITY

 

If, at any time, any provision
of a Notes Document is or becomes illegal, invalid or unenforceable in any respect under any law of any jurisdiction, neither the legality,
validity or enforceability of the remaining provisions nor the legality, validity or enforceability of such provision under the law of
any other jurisdiction will in any way be affected or impaired.

 

		18.	REMEDIES AND WAIVERS

 

No failure to exercise, nor any
delay in exercising, on the part of the Investor, any right or remedy under a Notes Document shall operate as a waiver of any such right
or remedy or constitute an election to affirm any Notes Document. No election to affirm any Notes Document on the part of the Investor
shall be effective unless it is in writing. No single or partial exercise of any right or remedy shall prevent any further or other exercise
or the exercise of any other right or remedy. The rights and remedies provided in each Notes Document are cumulative and not exclusive
of any rights or remedies provided by law.

 

		19.	AMENDMENTS AND WAIVERS

 

Any term of the Notes Documents
(including this Clause) may be amended or waived only with the consent of the Investor and the Issuer.

 

     

     

    

 

		20.	ASSIGNMENTS AND TRANSFERS

 

		(a)	The Investor may assign and transfer all or any of its rights, benefits and obligations
under this Agreement to any of its Affiliates or its successors. Prior to the occurrence of an Event of Default, such assignments and
transfers (as well as exposure transfers) will be permissible only as long as the Swiss Non-Bank Rules are respected.

 

		(b)	Except for any transfer pursuant to paragraph (a) of this Clause 20 and further
provided that these assignments or transfers are to a Swiss Qualifying Bank, no Party shall be entitled to assign and transfer all or
any of its rights, benefits and obligations under this Agreement without the other Parties' prior written consent, provided that the Investor
shall not be required to obtain the Issuer's consent in connection with the grant of any security (including any charge or assignment,
by way of security) over any of the Investor's rights under this Agreement in favour of any of its lenders or other persons providing
to that Investor any loan or other financing arrangement for the Investor's subscription of all or a portion of the Notes to be subscribed
by it pursuant to this Agreement, provided such grant of security does not lead to a violation of the Swiss Non-Bank Rules. For the avoidance
of doubt, it shall not be reasonable for the Issuer to withhold its consent as long as there are not more than five lenders that are not
Swiss Qualifying Banks in aggregate under this Agreement.

 

		(c)	For the avoidance of doubt, this Clause 20 shall not apply to the transfer by the
Investor of any Notes, which transfers are solely governed by the Conditions.

 

		21.	NON-DISCLOSURE OF NON-PUBLIC INFORMATION

 

The Issuer covenants and agrees
that it shall refrain from disclosing, and shall cause its officers, directors, employees, advisors and agents to refrain from disclosing,
any material non-public information to the Investor without also disseminating such information to the public.

 

		22.	ENTIRE AGREEMENT

 

This Agreement (including the
Schedules hereto and the documents and instruments referred to in this Agreement that are to be delivered pursuant to this Agreement)
constitutes the entire agreement among the Parties and supersedes any prior understandings, agreements or representations by or among
the Parties, or any of them, written or oral, with respect to the subject matter of this Agreement.

 

		23.	COUNTERPARTS AND CONCLUSION OF CONTRACT

 

		(a)	This Agreement may be executed in any number of counterparts, and this has the
same effect as if the signatures on the counterparts were on a single copy of this Agreement.

 

		(b)	This Agreement may be concluded by an exchange of signed signature pages, transmitted
by way of fax or attached as an electronic photocopy (.pdf, .tif, etc.) to email.

 

		24.	GOVERNING LAW AND JURISDICTION

 

		24.1	Governing law

 

This Agreement is governed by the
laws of Switzerland.

 

		24.2	Jurisdiction

 

Each Party agrees that any legal

liabilities are transferred to one or several other companies),

 

		(iii)	resolve, agree to, or implement any other corporate reorganisation (including,

determined, are reasonably likely to have a Material Adverse Effect;

Adverse Effect; and

 

		(iii)	promptly, subject to any statutory or regulatory limitation under applicable law,
on request, such further information regarding the financial condition, assets and operations of the Issuer as any Noteholder may reasonably
request.

applied to that interest payment (as provided for in Condition 6 (Interest)) in the absence of this paragraph (c), divided by (ii)
1 minus the rate at which the relevant Swiss Withholding Tax deduction is required to be made (where the rate at which the relevant tax
deduction is required to be made is for this purpose expressed as a fraction of one (1) rather than as a percentage), and (B) (i) the
Issuer shall be obliged to pay the relevant interest at the adjusted rate in accordance with this paragraph (c). Each relevant Noteholder
shall promptly co-operate in completing any procedural formalities to possible reclaim the Swiss Withholding Tax deducted. If and to the
extent a Noteholder receives a refund of Swiss Withholding Tax, it shall forward such amount, after deduction of costs, to the Issuer,
unless an Event of Default is continuing. Nothing in this paragraph shall interfere with the Noteholder's right to arrange its tax affairs
in whatever manner it thinks fit and, without limiting the foregoing, no Noteholder shall be under any obligation to claim any Swiss Withholding
Tax refund in priority to any other claims, relieves, credits or deductions available to it.

 

     

     

    

 

		7.	PAYMENTS

 

		(a)	Payment of Principal and Interest: Payment of principal, interest
(after deduction of the then applicable Swiss Withholding Tax: see Condition 11 (Taxation)) and any other payments in cash to be
made under these Conditions will be made available (unless a contrary indication appears in a Notes Document) for value on the due date
at the time and in such funds specified by the relevant Noteholder as being customary at the time for settlement of transactions in dollars
in the place of payment.

 

		(b)	The Issuer undertakes that payments shall be made in freely disposable funds as specified
by the relevant Noteholder as being customary at the time for settlement of transactions in dollars in the place of payment without collection
cost to the Noteholders, and, unless otherwise provided for by applicable law, without any restrictions and whatever the circumstances
may be, irrespective of nationality, residence or domicile of the Noteholders and without requiring any affidavit or the fulfilment of
any other formality, except for the fulfilment of the requirement set out in paragraph (c) below.

 

		(c)	Delay in Payment: Noteholders shall not be entitled to any interest
or other payment in respect of any delay in payment resulting from the due date for payment not being a Business Day.

 

		8.	CONVERSION RIGHTS

 

		(a)	Conversion Rights: Subject to the other provisions of this Condition
8, each Note shall entitle the holder thereof to convert the Principal Amount of that Note plus interest accrued thereon (calculated on
the basis of the Cash Interest Rate) until the Conversion Date (the "Conversion Amount") to be settled by converting
the Conversion Amount into Issuer Shares at the Conversion Ratio as determined in accordance with Condition 8(b) (Conversion Ratio
and Conversion Price), credited as fully paid. Each such right of a Noteholder to require a conversion of the Conversion Amount into
Issuer Shares at the Conversion Ratio is herein referred to as the "Conversion Right" and together the "Conversion
Rights" and the settlement of the Conversion Amount via the conversion of such amount into Issuer Shares at the Conversion Ratio
is herein referred to as a "Conversion".

 

		(b)	Conversion Ratio and Conversion Price: The conversion ratio (the
"Conversion Ratio") will be determined by converting the Conversion Amount into CHF, using the Noteholder's Rate of Exchange
on the Conversion Date and dividing the resulting figure by the Conversion Price prevailing on the Conversion Date. Any remainder smaller
than CHF 10 shall not be paid.

 

		(c)	Conversion Price B Conversions: Notwithstanding anything to the contrary
set out in Condition 8(b) (Conversion Ratio and Conversion Price), the Noteholder shall have the right to:

 

		(i)	convert each calendar month a Conversion Amount of up to 12.5% of the initial
aggregate principal amount of all issued Tranches into Issuer Shares whereby the Conversion Ratio will be determined by converting the
Conversion Amount into CHF, using the Noteholder's Rate of Exchange on the Conversion Date and dividing the resulting figure by the Conversion
Price B. Any remainder smaller than CHF 10 shall not be paid. For the avoidance of doubt, the receipt of a Redemption Notice shall in
no way restrict the Noteholder from exercising the conversion right according to this Condition 8(c)(i) as long as the Notes have not
been cancelled in accordance with Condition 10(c). The Issuer shall, in its sole discretion, have the right to waive the limit of 12.5%.
For the avoidance of doubt, the Investor can convert more than the 12.5% if the daily VWAP is above the Fixed Conversion Price.

 

     

     

    

 

		(ii)	convert, upon occurrence of an Event of Default, a Conversion Amount equalling
the sum of the aggregate principal amount of all issued and unconverted Notes, accrued interest and premium (if any) and the Make-whole
Amount (if applicable) into Issuer Shares whereby the Conversion Ratio will be determined by converting the Conversion Amount into CHF,
using the Noteholder's Rate of Exchange on the Conversion Date and dividing the resulting figure by the Conversion Price B. The number
of Issuer Shares to be delivered upon Conversion shall be rounded down to the next full number. Any remainder smaller than CHF 10 shall
not be paid.

 

		(iii)	convert, upon receipt of a Redemption Notice, a Conversion Amount of up to 12.5%
of the initial aggregate principal amount of all issued Tranches into Issuer Shares whereby the Conversion Ratio will be determined by
converting the Conversion Amount into CHF, using the Noteholder's Rate of Exchange on the Conversion Date and dividing the resulting figure
by the Conversion Price B. Any remainder smaller than CHF 10 shall not be paid. For the avoidance of doubt, the conversion right according
to this Condition 8(c)(iii) may be exercised in addition to the conversion right according to Condition 8(c)(i). The Issuer shall, in
its sole discretion, have the right to waive the limit of 12.5%.

 

		(d)	Conversion Notices: A Noteholder may exercise its Conversion Rights
at any time during the term of the relevant Note (the "Exercise Period") by serving a Conversion Notice to the Issuer
whereupon the Issuer shall procure the issue or transfer and delivery to, or as directed by, that Noteholder of Issuer Shares credited
as fully paid in accordance with Condition 8(i) (Delivery of Issuer Shares). If the Conversion Notice is delivered after the end
of normal business hours in Zurich, Switzerland, or on a day which is not a Business Day, such delivery shall be deemed for all purposes
of this Conditions to have been made on the following Business Day.

 

		(e)	Conversion at Maturity: lt is understood and agreed that the Investor
is obliged to request Conversion of each Convertible Note held by the Investor prior to the Maturity Date except in case an Event of Default
has occurred and the Investor hence irrevocably undertakes to request Conversion of all outstanding Convertible Notes prior to the Maturity
Date. To the extent the Investor has failed to request Conversion prior to the date falling ten (10) Business Days prior to the Maturity
Date, the Issuer shall be authorized to request Conversion on behalf of the Investor during the last ten (10) Business Days immediately
prior to the Maturity Date. Such Conversion shall be made through the Issuer (or any person designated by the Issuer) completing a Conversion
Notice on behalf of the Investor. A copy of such Conversion Notice shall immediately be sent to the Investor. The Conversion will take
place at the lower of the Fixed Conversion Price and Conversion Price B.

 

		(f)	Exercise of Conversion Right: The Conversion Right may be exercised
at any time during the Exercise Period in one or multiple instances and with respect to any Conversion Amount, provided that each conversion
represents a round whole number of Notes exceeding 1 (i.e. the "minimum" Conversion Amount is USD 100,000 and Conversion Amounts
must be in multiples of USD 100,000) and the maximum single Conversion Amount is USD 2,500,000 (unless such limit to the maximum single
Conversion Amount is waived by the Issuer), always provided that such maximum single Conversion Amount shall not apply to Conversion Price
B Conversions according to section 8(c) (Conversion Price B Conversions). Upon the exercise of the Conversion Right by the relevant
Noteholder, the respective Conversion Amount shall be deemed to become immediately due and payable and upon delivery of the relevant number
of Issuer Shares, the respective Conversion Amount shall be deemed to be settled.

 

     

     

    

 

		(g)	Conversion Date: The conversion date in respect of a Conversion Amount
(the "Conversion Date") shall be the date on which a Conversion Notice has been received or is deemed to have been received
in accordance with Condition 8(d) (Conversion Notices).

 

		(h)	Conversion Limitation: Notwithstanding anything to the contrary
set out in this Condition 8 (Conversion Rights), no Conversion may take place if as a result of such Conversion the relevant Noteholder
would beneficially own in excess of 9.99% per cent. of the outstanding share capital of the Issuer (as computed pursuant to Rule 13d-
3 promulgated under the U.S. Securities and Exchange Act of 1934)(the "Conversion Limitation"). If as of the time of Maturity
the Noteholder exceeds the Conversion Limitation or the Noteholder may be deemed an “affiliate” of the Company, the Note shall
be extended, at the election of the Investor, at a maximum 3 times for a period of 2 months each (i.e. maximum 6 months in total) prior
to the conversion according to Section 8(e)(Conversion at Maturity). The word “affiliate” shall be defined as provided
in Rule 501(b) under the Securities Act of 1933

 

		(i)	Delivery of Issuer Shares:

 

		(i)	Issuance of Issuer Shares: The Issuer Shares to be delivered upon the exercise
by a Noteholder of a Conversion Right pursuant to this Condition 8 shall be delivered from Issuer Shares held in treasury by the Issuer
or its Subsidiaries or newly issued from the Issuer's conditional share capital (bedingtes Aktienkapital) or the Issuer's authorized
share capital (genehmigtes Aktienkapital), with the same entitlements as the other outstanding Issuer Shares, except that the Issuer
Shares so delivered will not give any right for any dividend or other distribution declared, paid or made by reference to a Record Date
prior to the Conversion Date and except that the voting rights may not be exercised unless the person designated in the Conversion Notice
as recipient of the Issuer Shares is registered as the holder of the Issuer Shares in the Issuer's share register (Aktienbuch).

 

		(ii)	Delivery of Issuer Shares: The Issuer will use best efforts to effect delivery
of the Issuer Shares within not more than one (1) Trading Day after the Conversion Date; in any event, the Issuer will effect delivery
of the Issuer Shares within not more than two (2) Trading Days after the Conversion Date through the Intermediary in accordance with directions
given by the Noteholder in the relevant Conversion Notice and enter the Noteholder (or any designee of the Noteholder to which relevant
Issuer Shares are transferred in accordance with the Conversion Notice) into the Issuer's share register (Aktienbuch). For the
avoidance of doubt, it is acknowledged that the first Delivery of Issuer Shares may take up to five (5) Trading Days, subject to the compliance
requirements of the Issuer and the Investor’s respective custodian banks and any verification checks that they are required to carry
out. As long as the Issuer undertakes its best efforts to effect delivery of the Issuer Shares, this will not be considered an Inability
to issue Conversion Shares pursuant to the immediately following paragraph.

 

     

     

    

 

		(iii)	Inability to issue Conversion Shares: If the Issuer is unable to deliver the
Issuer Shares to the Investor within two Trading Days after the Conversion Date in compliance with this Agreement for any reason, then
without limiting any other rights of the Investor under this Agreement, the Investor may (but is not required to) either: (a) both (i)
hold over the Conversion Price that would have applied to the Conversion (the "Applicable Price"); and (ii) once the
Company’s inability to deliver the Issuer Shares is overcome, apply the Applicable Price to determine the number of Issuer Shares
that are then issuable and require such number of Issuer Shares to be delivered by the Issuer; or (b) require the Issuer to repay the
Alternative Amount (instead of issuing the Issuer Shares). The Alternative Amount, in relation to any delivery of Issuer Shares, means
(yy) 103% of the Conversion Amount that would have otherwise been the subject of the delivery of Issuer Shares if delivery is made within
less than 5 Trading Days and (zz) 108% of the Conversion Amount that would have otherwise been the subject of the delivery of Issuer Shares
if delivery is made on the 5th Trading Day or later. For the avoidance of doubt, this section shall not apply in case the inability
to deliver the Conversion Shares is solely the Investor's fault for not instructing its share agent properly.

 

		(iv)	Taxes and other costs. Any Swiss Federal Stamp Duty, if due, as well as
the fee of the Relevant Exchange, if any, payable upon the delivery of the Issuer Shares to the Noteholder (or any designee of the Noteholder)
upon a Conversion will be paid or reimbursed by the Issuer.

 

		9.	NOMINAL VALUE MAKE-WHOLE

 

At the Noteholder’s discretion,
if the Conversion Price B on the relevant Conversion Date is lower than the nominal value of the Shares, the Noteholder shall accept to
receive a number of Shares equal to the Conversion Amount divided by the nominal value of the Issuer Shares, provided that the relevant
Noteholder also receives a cash contractual penalty payment of an amount equal to the closing price of the Issuer Share on the Conversion
Date multiplied by the difference between (i) the Conversion Amount divided by the applicable Theoretical Conversion Price and (ii) the
Conversion Amount divided by the nominal value of the Issuer Shares (the "Nominal Value Make-Whole Payment").

 

		10.	REDEMPTION AND PURCHASE

 

		(a)	Redemption at the Option of the Issuer: If the Voluntary Prepayment
Requirement is met, the Issuer may, by giving not less than 15 Business Days' (or such shorter notice the relevant Noteholder may agree)
prior notice to the Noteholders in accordance with Condition 14 (Notices) (which notice shall be irrevocable and shall specify
the date fixed for redemption) (the "Redemption Notice"), redeem the Notes at their Principal Amount together with accrued
and unpaid interest to (and including) the day of redemption and together with the Make-whole Amount pertaining to each Note. For the
avoidance of doubt, upon receipt of the Redemption Notice until actual Redemption, the Investor has the right to convert the amount to
be redeemed according to the Redemption Notice at the applicable Fixed Conversion Price.

 

		(b)	No other redemption: The Issuer shall not be entitled to redeem the
Notes otherwise than as provided in Condition 9(a) (Redemption at the Option of the Issuer).

 

		(c)	Cancellation of Notes: All Notes which are redeemed or converted
pursuant to Condition 8 (Conversion Rights) and this Condition 9 (Redemption and Purchase) will be cancelled and may not
be reissued or resold.

 

		11.	TAXATION

 

All payments of principal and
interest in respect of the Notes shall be made free and clear of, and without withholding or deduction for, any Taxes imposed, levied,
collected, withheld or assessed by or on behalf of any relevant jurisdiction, unless such withholding or deduction is required by law.
In that event, the Issuer shall pay such additional amounts as will result in the receipt by the Noteholder of such amounts as would have
been received by them if no such withholding or deduction had been required.

 

     

     

    

 

		12.	PRESCRIPTION

 

Claims for payment of the Principal
Amount or interest cease to be enforceable by legal action in accordance with the applicable Swiss statute of limitations (presently after
10 years in case of claims for payment of the Principal Amount and after five years in case of claims of payment of interest, in each
case from the relevant due date for payment).

 

		13.	EVENTS OF DEFAULT

 

Anson Investments Master Fund
LP (in its capacity as initial Noteholders' Representative) or any other person appointed by the Majority Noteholders as Noteholders'
Representative in its place (the "Noteholders' Representative") has the right but not the obligation to notify the Issuer
in writing (such notice, an "Acceleration Notice") that the Notes are, and shall thereupon immediately become, due and
repayable, at their Principal Amount, together with accrued interest and premium (if any) and together with the Make-whole Amount pertaining
to each Note, upon the occurrence of any of the following events (each, an "Event of Default"):

 

		(a)	Non-payment: The Issuer does not pay on the due date any amount (including,
without limitation, principal, premium or interest payable), in each case in respect of the Notes at the place at and in the currency

		(A)	administrative or technical error; or

 

		(B)	a Disruption Event; and

 

		(ii)	payment is made within three (3) Business Days of its due date.

 

		(b)	Breach of the Share Coverage Covenant: If, at any time, the Issuer
does not have a number of shares reserved and available exclusively for the Issuer in case of the conversion of any Notes equal to 150%
of the outstanding aggregate principal amount converted into CHF using the Noteholder's Rate of Exchange divided by the applicable Conversion
Price B, and the Issuer has not rectified this within a period of 20 Trading Days following the initial breach, then this is considered
a Breach of the Share Coverage Covenant.

 

		(c)	Failure to deliver Issuer Shares upon Conversion: The Issuer fails

remedy; or

 

		(ii)	being a failure which is, as reasonably determined by the Noteholders' Representative,
capable of remedy and which remains un-remedied for 10 Business Days (or such longer period as the Noteholders' Representative may agree)

of Default under this Condition 13(d) shall be deemed to have occurred if the aggregate amount of Financial Indebtedness or commitment
for Financial Indebtedness falling within sub-paragraphs (i) to (iv) above is less than US$150,000 (or its equivalent in other currency
or currencies);

 

		(f)	Insolvency:

not served an Acceleration Notice itself. The legally valid resolution of the Noteholders' meeting to serve an Acceleration Notice shall

by agreement between the Issuer and the Noteholders' Representative (acting in its capacity as such) on behalf of the Noteholders provided
that such amendment (a) is of a formal, minor or technical nature and/or is made to correct a manifest error and (b) is not materially
prejudicial to the interests of the Noteholders. Notice of any such amendment shall be published in accordance with Condition 14 (Notices).
