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:

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).

in relation to the Accelerated Notes Tranches (including the respective Additional Accelerated Notes Tranche Closing Date) 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 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 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%.
