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 applicable Conversion Price B (95% or 90%). 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.

 

    6 

     

    

 

		(iv)	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%.

 

		3.	General Terms.

and execution of this Amendment, whereby the corresponding amount (i) shall be deducted directly from the Subscription Price of the next
Notes Tranche or (ii), if no Notes Tranche is subscribed for within 30 days of the date of this Amendment, shall be paid in cash to the
Investor or such other party designated by the Investor.

 

		(F)	This Amendment may be executed in counterparts, each of which when so executed and delivered will be deemed an original, and all of
such counterparts together will constitute but one and the same agreement. Facsimile, .pdf and other electronic copies of signatures will
be treated as original signatures for all purposes.

 

		(G)	If there is an express conflict between the terms of this Amendment and the terms of the Subscription Agreement, the terms of this

"Conversion Price B" in relation to the
Initial Notes Tranche, the Second Notes Tranche, the Third Notes Tranche, the Fourth Notes Tranche, the Fifth Notes Tranche and any Additional
Notes Tranches means 95% of the lowest daily VWAPs of one Issuer Share, as applicable, during the five (5) consecutive Trading Days ending
on (and including) the Trading Day immediately preceding the Conversion Date, rounded down to the nearest Swiss Cent (CHF 0.01), and in
relation to the Accelerated Notes Tranches means 90% of the lowest daily VWAPs of one Issuer Share, as applicable, during the ten (10)
consecutive Trading Days ending on (and including) the Trading Day immediately preceding the Conversion Date, rounded down to the nearest

		(B)	Section 8 (c) Conversion Price B Conversions is amended in its entirety to read as follows:

 

		(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)	in relation to the Initial Notes Tranche, the Second Notes Tranche, the Third Notes Tranche, the Fourth Notes Tranche, the Fifth Notes
Tranche and any Additional Notes Tranches 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 (95%).
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)	in relation to the Accelerated Notes Tranches convert at any time at the discretion of Investor a Conversion Amount of up to 100%
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 (90%). 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).

 

		(iii)	convert, upon occurrence of an Event of Default, a Conversion Amount equaling 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 applicable Conversion Price B (95% or 90%). 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.

		(iv)	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%.
