or securities convertible or exchangeable into Borrower Shares or Other Securities (the rights referred to in (i) and (ii) collectively
and individually being the "Purchase Rights"), the Conversion Price shall be adjusted by multiplying the Conversion Price
in force immediately prior to such issue or grant by the result of the following formula:



(P curr
– R)/P curr



where:



Pcurr is the Current Market Price
by reference to whichever is the later of (x) the date on which the Borrower Shares are first traded ex-Purchase Rights on the
Relevant Exchange and (y) the Trading Day when the subscription or purchase price for Borrower Shares or Other Securities under

=(Now x Pcurr
+Nnewx(Prights+

Rights price; and



Nold

if Dividends have not yet been proposed, based on the Dividends paid in the immediately preceding financial year;



provided, however, that no such
adjustment shall be made if the subscription or purchase price at which one new Borrower Share can be subscribed or purchased is
at least ninety (90) per cent of the Current Market Price on whichever is the later of (x) the date on which the Borrower Shares
are first traded ex-Purchase Rights on the Relevant Exchange or (y) the Trading Day when the subscription or purchase price for
the Purchase Right is announced, or, if the day the subscription or purchase price is announced is not a Trading Day, the next
following Trading Day;



| | (B) | in the event the Purchase Rights relate to Other Securities or to securities convertible or exchangeable

respect to any financial year, the Conversion Price shall be adjusted according to the formula set out in section 1(d) of this
Schedule 2.
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | In all other cases where there is more than one such Distribution on a given Trading Day, the Independent
Expert will determine the necessary adjustment.
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------



Such adjustment shall become effective,
in the case of sub-paragraph (i)(y) above, on the date on which the Distribution is made and, in the case of sub-paragraph (i)(x),
(ii) and (iii) above, on the sixth (6th) Trading Day after the Distribution Date and, in the case of sub-paragraph (i)(z) and (iii)
above, as determined by a Independent Expert.



| | (d) | Dividends
| | --- | ---------



If the Borrower pays a Dividend,
the Conversion Price shall be adjusted by multiplying the Conversion Price by the following fraction:



(Pcurr-D)/ Pcurr



where:



Pcurr	is the Current
Market Price with respect to the Effective Date; and



D       is
the portion of the Dividend attributable to one Borrower Share as set out



below



Any reference to D in the above
formula shall be replaced by



| | (i) | the cash amount in case of a cash dividend or a repayment of paid-in capital;
| | --- | -----------------------------------------------------------------------------



| | (ii) | an amount as calculated by the following formula in case of a stock dividend in lieu of a cash
dividend:
| | ---- | --------------------------------------------------------------------------------------------------------



Current Market Price - (Current
Market Price x (NOld / NNew))



where:



Current Market Price is the average
of the daily VWAP of one Borrower Share on each of the [***] consecutive Trading Days ending on and including the Trading Day
immediately prior to the Ex-Date;



Nold is the number of
Borrower Shares existing before the change in share capital; and





47







NNew
is the number of Borrower Shares existing after the change in share capital;



| | (iii) | an amount as calculated by the following formula in case of tradable put options in lieu of a cash
dividend (the "Put Option"):
| | ----- | -------------------------------------------------------------------------------------------------------------------------------



current market price x (P/N)



where:



current market price	is the
average of the daily VWAP of the Put Option on each of the five (5) consecutive Trading Days commencing on the Ex-Date;



P       is
the number of Put Options to be issued; and



N       is
the number of Borrower Shares existing prior to the Ex-Date.



Such adjustment shall become effective
on the Ex-Date and in case of Put Options according to sub-paragraph, (iii) above, on the sixth (6th) Trading Day following
the Ex-Date.



| | 2. | CALCULATION OF ADJUSTMENTS
| | -- | --------------------------



| | (a) | Each adjustment to be made pursuant to this Schedule 2 shall be calculated by the Lender and shall
(in the absence of manifest error) be binding on the Borrower. The Lender may engage the advice or services of any Independent
Expert whose advice or services it may consider necessary and rely upon any advice so obtained, and the Lender shall incur no liability
as against the Borrower in respect of any action taken, or not taken, or suffered to be taken, or not taken, in accordance with
such advice and in exercising due care according to established market practice.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | If in case of any adjustment the resulting Conversion Price is not an integral multiple of CHF
0.01 (one hundredth of a Swiss franc), it shaft be rounded to the nearest whole or multiple of CHF 0.01 (one hundredth of a Swiss
franc) with 0,005 being rounded upwards,
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | The Borrower will procure that a notice is sent to the Lender as soon as practicable after either
the date on which any adjustment to the Conversion Price becomes effective or, if no adjustment is required, the date on which
it is possible to determine that such is the case.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | RETROACTIVE ADJUSTMENTS
| | -- | -----------------------



| | (a) | If the Conversion Date in relation to any Conversion Amount is (i) before the relevant record date
for any issue, sale, grant or offer leading to an adjustment pursuant to section 1 of this Schedule 2, (ii) before publication
of the event leading to such Record Date, and (iii) before the relevant adjustment to the Conversion Price becomes effective under
section 1 (b) of this Schedule 2, and (iv) provided that the Borrower Shares will be delivered to the Lender after the Record Date,
the Borrower shall (conditional upon the relevant adjustment becoming effective) procure that there shall be issued to the converting
Lender such an additional number of Borrower Shares or additional cash amount (the "Additional
Consideration")as, together with the Borrower Shares delivered or to be delivered and the cash amounts to be transferred,
if applicable, on conversion of the relevant Conversion Amount is equal to the consideration (in form of cash amounts or Borrower
Shares as set out in sections 1 (b) and 1 (c) of this Schedule 2) which would have been required to be delivered on conversion
of such Conversion Amount if the relevant adjustment to the Conversion Price had in fact been made and become effective prior to
the Conversion Date (the "Retroactive
Adjustment").
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------





48







| | (b) | Without prejudice to the provisions of Clause 7 (Conversion),
upon a Retroactive Adjustment becoming effective in accordance with this section 3 of this Schedule 2, the delivery of the relevant
Additional Consideration shall be made within ten (10) Business Days after the first date it is possible to calculate such adjustment
but not earlier than the Record Date. Without prejudice to the foregoing and to mandatory provisions of applicable law, in the
event that an issue, sale, grant or offer leading to an adjustment pursuant to section 1 of this Schedule 2 is effected between
the above Conversion Date and the date of delivery of the relevant Additional Consideration, the Borrower shall request a Independent
Expert to determine the amount of the further consideration to be made to the Lender, whether in kind or in cash, so that the Lender
may be substantially treated as if it actually held the Additional Consideration on the Conversion Date.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4. | EVENTS NOT GIVING RISE TO ADJUSTMENTS
| | -- | -------------------------------------



No adjustment to the Conversion
Price will be made:



| | (a) | if Borrower Shares or Other Securities (including pre-emptive rights, options or warrants in relation
to Borrower Shares or Other Securities) are issued, offered or granted to, or for the benefit of, members of the board of directors,
officers, employees or advisors of the Borrower or any of its Subsidiaries or any associated company or to trustees to be held
for the benefit of any such person in any such case pursuant to any employee share or option scheme; or
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | if the Conversion Price would fall below the nominal value of a Borrower Share. In this case, the
Conversion Price will be adjusted to the nominal value of a Borrower Share and any remaining reduction of the Conversion Price
resulting from such adjustment or from any further adjustment will be carried forward and only be applied if and to the extent
the nominal value of a Borrower Share will be reduced.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------





49







| | 5. | OTHER EVENTS
| | -- | ------------



If the Lender determines after
consultation with the Borrower, that notwithstanding sections 1 and 2 of this Schedule 2 an adjustment should be made to the Conversion
Price as a result of one or more events or circumstances not referred to in section 1 of this Schedule 2 or circumstances including
circumstances listed in section 4 of this Schedule 2 have arisen which have an adverse effect on the (economic value of the) Conversion
Right and no adjustment to the Conversion Price under section 1 of this Schedule 2 would otherwise arise or is excluded according
to section 4 of this Schedule 2, the Lender shall engage the advice or services of a Independent Expert to determine as soon as
practicable what adjustment, if any, to the Conversion Price or amendment, if any, to the terms of this Schedule 2 is fair and
reasonable to take account thereof and the date on which such adjustment should take effect. If several events occur which become
effective on the same Trading Day and which would lead to an adjustment of the Conversion Price pursuant to section 1 of this Schedule
2, the decision as to the manner of calculating the adjustment of the Conversion Price shall be taken by the Independent Expert.
The decision of the Independent Expert shall be conclusive and binding on the Lender and the Borrower.



| | 6. | CORRECTION OF ADJUSTMENTS
| | -- | -------------------------



If an adjustment has been made
in accordance with section 1 of this Schedule 2 based on events or circumstances that subsequently are not implemented or are implemented
in a manner materially different than anticipated when calculating the adjustment, then the Borrower and the Lender shall determine
whether and to what extent the adjustment previously made shall be corrected. The Lender may engage the services of a Independent
Expert to determine whether and to what extent a correction shall be made. The decision of the Independent Expert shall be conclusive
and binding.



| | 7. | APPOINTMENT OF INDEPENDENT EXPERT
| | -- | ---------------------------------



If the Borrower and the Lender
do not mutually agree on an Expert within seven (7) days from the beginning of the appointment process, each of the Borrower and
the Lender shall select an Expert, whereby the so elected Experts shall select together a third Expert. In case the two selected
Experts do not mutually agree on a third Expert within seven (7) days after being appointed, each of them shall select another
Expert, whereby a Swiss Notary Public appointed by the Lender will pick one of these two Experts as third Expert by drawing lots.
In the case of the appointment of three Experts references in this Agreement to an Independent Expert shall be deemed to refer
to these three Experts, deciding by majority decision. Decisions of the Independent Expert shall be final and binding on the Borrower
and the Lender. The Lender shall incur no liability against the Borrower in respect of any action taken, or suffered to be taken,
in accordance with such decision and in good faith. The fees and costs of the Independent Expert shall be borne by the Borrower.
