SCHEDULE 2
ADJUSTMENT MECHANICS

1. EVENTS LEADING TO ADJUSTMENTS TO THE CONVERSION PRICE

(a) Increase of capital by means of capitalization of reserves, profits or premiums by distribution of Borrower Shares, or division or consolidation of Borrower Shares

In the event of a change in the Borrower's share capital as a result of capitalization of reserves, profits or premiums, by means of the distribution of Borrower Shares, save for a distribution of Borrower Shares as a Dividend as set out in section 1(d) of this Schedule 2, and in the event of division or consolidation of Borrower Shares, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately prior to such change by the result of the following formula:

where:

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

N_New is the number of Borrower Shares existing after the change in share capital.

Such adjustment shall become effective on the date on which such Borrower Shares are distributed or, En the event of division or consolidation of Borrower' Shares, on the first day the Borrower Shares are traded on the new basis on the Relevant Exchange.

(b) Issue of Borrower Shares or Other Securities by way of conferring subscription or purchase rights

If (i) the Borrower grants to holders of Borrower Shares any rights or options, warrants or other rights to subscribe for or acquire Borrower Shares, Other Securities or securities convertible or exchangeable into Borrower Shares or Other Securities, or (ii) any third party with the consent of the Borrower issues to holders of Borrower Shares any rights, options or warrants to purchase any Borrower Shares, Other Securities 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 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; and

43

R is the value of the Purchase Right relating to one Borrower Share or Other Security, such value to be calculated as follows:

(A) In the event the Purchase Rights relate to Borrower Shares:

R = P_curr - TERP

where:

TERP = (Now x P_curr + N_new x (P_rights + Div)) / (N_old + N_new) and:

TERP is the theoretical ex-Purchase Rights price; and

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

N_new is the number of offered Borrower Shares contemplated to be newly issued; and

P_rights is the price at which one new Share can be subscribed, exercised or purchased; and

Div is the amount (in CHF) by which the entitlement to Dividends per existing Share exceeds the entitlement to Dividends per new Borrower Share, (x) if Dividends have already been proposed to the general meeting of shareholders but not yet paid, based on the proposed amount of the Dividends, or(y) 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 into Borrower Shares or Other Securities and where such Purchase Rights are traded on a regulated stock exchange in Switzerland, the European Union, the United States of America, Canada or Japan:

where:

R = N_rights X P_rights

N_rights is the number of Purchase Rights granted per Borrower Share; and

P_rights is the VWAP of the Purchase Rights on the Relevant Exchange (or, if no dealing is recorded, the arithmetic mean of the bid and offered prices) during the time Purchase Rights are traded, but not longer than the first ten (10) Trading Days.

44

(C) in all other cases where neither of the previous paragraphs (A) or (B) is applicable, R will be determined by a Independent Expert.

Such adjustment shall become effective:

(i) in the case of sub-section (A) above, on the first day on which the Borrower Shares are traded ex-Purchase Rights on the Relevant Exchange;

(ii) in the case of sub-section (B) above, five (5) Trading Days after (x) the end of the period during which the Purchase Rights are traded or (y) the tenth (10th) Trading Day of the Purchase Rights, whichever is sooner; and

(iii) in the case of sub-section (C) above, on the date determined by the Independent Expert.

(c) Spin-offs and capital distributions other than Dividends

If, in respect of a spin-off or a capital distribution other than Dividends as set out in section 1(d) of this Schedule 2, the Borrower shall issue or distribute to holders of its Borrower Shares any assets, evidence of indebtedness of the Borrower, shares or other rights (other than as referred to in section 1(b) of this Schedule 2) (the "Distribution"), the Conversion Price shall be adjusted as follows:

(i) In case the Distribution (x) consists of securities that will be traded on a regulated stock exchange in Switzerland, the European Union, the United States of America, Canada or Japan, (y) consists of securities that are traded on a regulated stock exchange in Switzerland, the European Union, the United States of America, Canada or Japan or (z) has otherwise a value which is determinable by reference to a stock exchange quotation or otherwise, by multiplying the Conversion Price in force immediately prior to such issue or distribution by the result of the following formula:

(P_curr – D)/P_curr

where:

P_curr is the Current Market Price by reference to the date on which the Borrower Shares are first traded ex-Distribution on the Relevant Exchange following the relevant Distribution; and

45

D is equal to (i) in case of sub-paragraph (i)(x) above, the current market price of the Distribution (in CHF) on the Relevant Exchange, calculated on a per Borrower Share basis, as determined by the Lender, or (ii) in case of sub-paragraph (i)(y), the current market price of the Distribution (in CHF) on the Relevant Exchange on the date by reference to which P_curr has been determined, calculated on a per Borrower Share basis, as determined by the Lender, or (iii) in case of sub-paragraph (i)(z), as determined by a Independent Expert.

whereby for purposes of this provision, the current market price (to determine D) in case of sub-paragraph (i)(x) above shall be deemed to be the average of the VWAPs on the [***] consecutive Trading Days commencing on the date on which the Borrower Shares are first traded ex-Distribution on the Relevant Exchange, and in case of sub-paragraph (i)(y) shall be deemed to be the average of the VWAPs on the [***] consecutive Trading Days ending on and including the Trading Day preceding the day on which the Borrower Shares are first traded ex-Distribution. When calculating the average of the VWAPs the gross dividend amount (or any other entitlement), if any, of any dividend (or any other entitlement) paid during either of the above mentioned periods of [***] consecutive Trading Days, shall be added back to the VWAPs on each of the Trading Days on which the Borrower Shares are traded ex-dividend (or any other entitlement).

(ii) In all other cases and where there is one (but not more) Distribution on a given Trading Day, by multiplying the Conversion Price in force immediately prior to such issue or distribution by the result of the following formula:

P_after/P_before

where:

P_after is the current market price per Share after the date of such Distribution (the "Distribution Date"); and

P_before is the current market price per Borrower Share before the Distribution Date;

whereby for purposes of this provision the current market price per Borrower Share shall be deemed to be tire average of the VWAPs, (x) in the case ofPbefore, on the five (5) consecutive Trading Days before the Distribution Date, and (y) in the case of P_after on the live (5) consecutive Trading Days after the Distribution Date, as determined by the Lender. When calculating the average of the VWAPs the gross dividend amount (or any other entitlement), if any, of any dividend paid (or any other entitlement) during either of the above mentioned periods of five (5) consecutive Trading Days, shall be added back to the VWAPs on each of the Trading Days on which the Borrower Shares are traded ex-dividend (or any other entitlement).

46

(iii) If the Borrower issues or distributes to its shareholders tradable put options as a Dividend with 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:

(P_curr-D)/ P_curr

where:

P_curr 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 (N_Old / N_New))

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;

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

47

N_New 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 (6^th) 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.
