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%.
