Amounts if it had presented such Note for payment on any date within such 30-day period; 

(3) the failure of the Holder or beneficial owner to comply with a timely request of the Company or any successor entity
addressed to the Holder or beneficial owner, as the case may be, to provide information, documentation and certification concerning such Holder’s or beneficial owner’s nationality, residence, identity or connection with any Relevant
Jurisdiction, if and to the extent that due and timely compliance with such request would under applicable law, regulation or administrative practice have reduced or eliminated any withholding or deduction as to which Additional Amounts would have
otherwise been payable to such Holder; or 
 (4) the presentation of such Note (where presentation is required) for payment
in the Relevant Jurisdiction, unless such Note could not have been presented for payment elsewhere;

(3) Trading Days after the end of the Fair Note Value Calculation Period. If the Shareholder Resolution is not passed by the Resolution Deadline, the Initial Non-Conversion Period will be automatically
extended through (i) the expiration of the Shareholder Event Notice Period, or (ii) the redemption of the Notes, if the Company exercises such right. To the extent not superseded by specific terms of this Section 2.06, Article XI of

 ARTICLE 3 

INTEREST 

SECTION 3.01. Interest Rate. The Notes shall bear interest from the most recent Interest Payment Date to which interest has been
paid or duly provided for, or, if no interest has been paid, from the Issue Date, at a rate of 5.50% per annum (the “Stated Interest Rate”) on the stated principal amount, payable quarterly in arrears on each Interest Payment Date
(subject to deferral as described in Section 3.02), to the Persons whose names the Notes are registered in the Security Register at the close of business on the Regular Record Date immediately preceding the Interest Payment Date. Interest on
the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months. Any payment required to be made on any day that is not a Business Day shall
be made on the next succeeding Business Day. 
 SECTION 3.02. Optional Deferral of Interest Payments. Interest shall be due and
payable on each Interest Payment Date unless the Company elects not to pay such interest on such Interest Payment Date (which the Company may elect to do on any Interest Payment Date unless such Interest Payment Date is a Mandatory Interest Payment
Date). Any such election not to pay interest shall not constitute a default of the Company, an Enforcement Event or any other breach of obligations under the Indenture or the Notes or for any other purpose. If the Company decides not to pay the
interest on an Interest Payment Date, the Company shall notify the Agents and the Holders in accordance with the Indenture not less than ten and not more than 15 Business Days prior to the relevant Interest Payment Date. 

Any interest not paid because of such an election of the Company shall constitute “Optionally Deferred Payments.” Optionally
Deferred Payments shall themselves bear interest at the Stated Interest Rate (the “Additional Interest Amount”). Additional Interest Amounts shall accrue from the Interest Payment Date on which such amounts were initially deferred,
and shall compound on subsequent Interest Payment Dates, quarterly, at the Stated Interest Rate. 
 The nominal amount of any Optionally
Deferred Payments together with any Additional Interest Amount shall constitute “Optionally Outstanding Payments.” 

SECTION 3.03. Payment of Optionally Outstanding Payments. The Company may pay outstanding Optionally Outstanding Payments (in
whole but not in part) at any time upon giving not less than ten and not more than 15 Business Days’ notice to the Agents and to the Holders in accordance with the Indenture (which notice shall be irrevocable and will constitute an obligation
of the Company to pay the relevant Optionally Outstanding Payments on the payment date specified in such notice). Such notice will also specify the record date, which date shall be no less than 5 Business Days following the date of such notice, for
determining the Holders to which such Optionally Outstanding Payments shall be made. 
 Any outstanding Optionally Outstanding Payments
shall become due and payable (in whole but not in part) on any Mandatory Interest Payment Date. 

  
 21 













 SECTION 3.04. Accrual of Interest. Except as otherwise provided in the
Indenture, in the event of a voluntary early conversion with respect to a Note prior to the Maturity Date pursuant to Section 4.03(a) by the Holder other than during a Special Voluntary Conversion Period, such Note shall cease to bear interest
from, and including, the Interest Payment Date immediately preceding the relevant Conversion Date or, if the Conversion Date occurs prior to the first Interest Payment Date, the Issue Date. 

ARTICLE 4 
 CONVERSION

 SECTION 4.01. Mandatory Conversion. 

(a) Mandatory Conversion at Maturity. Unless previously converted, or purchased and cancelled, each $25 principal amount of Notes shall
be mandatorily converted on the Maturity Date into a number of Settlement Shares equal to the Relevant Conversion Ratio (subject to adjustment until the Settlement Date as set out in Section 4.06). On the Maturity Date, the Company shall, in
addition, pay any Optionally Outstanding Payments and any other accrued and unpaid interest to, but excluding, the Maturity Date. 
 (b)
Accelerated Mandatory Conversion. Following the Initial Non-conversion Period, if an Accelerated Mandatory Conversion Event occurs prior to the 25th Scheduled Trading Day preceding the Maturity Date,
the Company shall give notice thereof (an “Accelerated Conversion Notice”), including the resulting Accelerated Mandatory Conversion Date, to the Holders, the Trustee, the Securities Administrator and the Conversion Agent in
accordance with the Indenture without undue delay. Each $25 principal amount of Notes will be mandatorily converted on any Accelerated Mandatory Conversion Date into such number of Settlement Shares as is equal to the Maximum Conversion Ratio in
effect on the date on which the notice pursuant to this Section 4.01(b) is published (subject to adjustment until the Settlement Date as set out in Section 4.06). On the Settlement Date, the Company shall, in addition, pay the Make-whole
Amount, any Optionally Outstanding Payments and any other accrued and unpaid interest to, but excluding, the Settlement Date. 
 (c) Early
Mandatory Conversion at the Option of the Company. Subject to a period of at least 30 days’ and not more than 60 days’ prior notice to the Holders in accordance with the Indenture, the Company may, at any time during the Conversion
Period, mandatorily convert the outstanding Notes, in whole but not in part, on the date of conversion fixed by the Company in the notice (the “Optional Mandatory Conversion Date”). Each $25 principal amount of Notes will be
mandatorily converted on the Optional Mandatory Conversion Date into such number of Settlement Shares as is equal to the Maximum Conversion Ratio in effect on the date on which the notice pursuant to this Section 4.01(c) is published (subject
to adjustment until the Settlement Date as set out in Section 4.06). On the Settlement Date the Company shall, in addition, pay the Make-whole Amount, any Optionally Outstanding Payments and any other accrued and unpaid interest to, but
excluding, the Settlement Date. 
 SECTION 4.02. Initial Non-conversion Period
Notwithstanding any other provision of this Indenture, the Notes will not be convertible under any circumstances prior to July 28, 2020 (such period of non-convertibility, as it may be extended
pursuant to Section 2.06, the “Initial Non-conversion Period”). 

  
 22 













 SECTION 4.03. Voluntary Conversion. 

(a) Voluntary Conversion at the Option of the Holder. Subject to and upon compliance with the provisions of this Article 4, each Holder
of a Note shall have the right (the “Voluntary Conversion Right”), at such Holder’s option, to convert each of its Notes in whole or in part on any Business Day during the Conversion Period; provided that no Holder may
exercise its Voluntary Conversion Right during any Excluded Period. In the event a Holder exercises its Voluntary Conversion Right, the number of Settlement Shares to be issued and/or delivered by the Company per $25 principal amount of Notes upon
conversion will be equal to the Minimum Conversion Ratio in effect on the Voluntary Conversion Date (subject to adjustment until the Settlement Date as set out in Section 4.06). On the Settlement Date, the Company shall, in addition, pay any
Optionally Outstanding Payments in respect of the Notes being converted. Accrued and unpaid interest from, and including, the preceding Interest Payment Date, if any, to, but excluding, the Conversion Date will be deemed to have been paid in full
rather than cancelled, extinguished or forfeited. 
 The Voluntary Conversion Right may not be exercised by a Holder if such Holder has
declared its Notes due and payable in accordance with Section 5.03. Any exercise of a Voluntary Conversion Right during a Special Voluntary Conversion Period shall be considered as an exercise of a Voluntary Conversion Right pursuant
Section 4.03(b). 
 Notwithstanding anything to the contrary in this Second Supplemental Indenture, if a Holder submits a Conversion
Notice (or, in the case of a conversion of a beneficial interest in a Global Note initiated by the Holder), the Company shall have the right within one Business Day to issue a notice of mandatory conversion fixing a date for conversion that complies
with Section 4.01(c) for all outstanding Notes, in whole but not in part, to the Trustee, the Securities Administrator, the Conversion Agent and the Holders. In that case, all outstanding Notes (including such Notes submitted for voluntary
conversion) will be converted into Settlement Shares at the Maximum Conversion Ratio as provided in such Section 4.01(c), and the Company will, in addition, pay the Make-whole Amount, any Optionally Outstanding Payments and any other accrued
and unpaid interest, all pursuant to Section 4.01(c). 
 In addition, and notwithstanding anything to the contrary in this Second
Supplemental Indenture, if the Company delivers an Accelerated Conversion Notice pursuant to Section 4.01(b) or a notice of mandatory conversion pursuant to Section 4.01(c), no Holder may convert its Notes pursuant to the Voluntary
Conversion Right. 
 (b) Voluntary Conversion upon the Occurrence of a Relevant Event. Each Holder who exercises its Voluntary
Conversion Right during a Special Voluntary Conversion Period has the right to convert its Notes in whole or in part into Settlement Shares at the Relevant Event Conversion Ratio. 

  
 23 













 In the event of a voluntary conversion during the Special Voluntary Conversion Period, the
number of Settlement Shares to be issued and/or delivered by the Company per $25 principal amount of Notes upon conversion will be equal to the Relevant Event Conversion Ratio (subject to adjustment until the Settlement Date as set out in
Section 4.06). 
 In the event of a voluntary conversion during a Special Voluntary Conversion Period, on the Settlement Date, the
Company shall, in addition, pay the Make-whole Amount, any Optionally Outstanding Payments and any other accrued and unpaid interest to, but excluding, the Settlement Date, in each case in respect of the Notes being converted. 

If a Relevant Event occurs after the Initial Non-conversion Period and prior to the 25th Scheduled
Trading Day preceding the Maturity Date, the Company shall give notice to the Holders, the Trustee and the Securities Administrator in accordance with the Indenture as soon as practicable after becoming aware thereof. 

Except as provided in Section 4.03(b), the conditions set forth in Section 4.03(a) shall apply to any a voluntary conversion during
a Special Voluntary Conversion Period. 
 If a Free-Float Event occurs prior to the 25th Scheduled Trading Day immediately preceding the
Maturity Date, the Company will give notice thereof to the Holders, the Trustee and the Securities Administrator in accordance with the Indenture without undue delay. 

SECTION 4.04. Fractional Shares. Fractions of Settlement Shares for the aggregate number of Notes of a Holder converted
pursuant to Section 4.01 or Section 4.03 shall be aggregated, and the result of such aggregation will be rounded down to the next full Settlement Share. Any remaining fraction of a Settlement Share will not be delivered and will not be
compensated in cash. The number of Settlement Shares to be delivered to the relevant Holder of the Notes so converted will be determined as provided above by the Calculation Agent. 

SECTION 4.05. Conversion Procedures. 

(a) Conversion; Settlement Shares. The issue and/or delivery of Settlement Shares by the Company upon conversion of the Notes pursuant
to Section 4.01 or Section 4.03 is made in lieu of any payment of principal of the Notes and will constitute a discharge of the Company from its corresponding obligation to repay the principal amount of the Notes in cash. Accordingly,
except as otherwise described in this Second Supplemental Indenture, as from the Settlement Date a Holder will not have any rights in relation to the Notes other than the right to have Settlement Shares issued and/or delivered, together with the
payment of the Make-whole Amount, if applicable, any Optionally Outstanding Payments and any other accrued and unpaid interest. The mandatory conversion pursuant to Section 4.01 shall not apply to (i) Notes that have been declared due by a
Holder in accordance with Section 5.03 and (ii) Notes held by the Company. Notes held by the Company shall be cancelled upon mandatory conversion of the Notes not held by it. 

Upon any conversion of the Notes, the Settlement Shares will be delivered to, or to the order of, the Depository or the European Share
Depositary, as applicable. Upon a conversion of the Notes, Settlement Shares will be New York Registry Shares; provided that a Holder or beneficial owner of a Note may elect to instead receive European Registry Shares pursuant to the terms
and conditions of Section 4.05(b). If a Holder or beneficial owner of a Note does not validly elect European Registry Shares and comply with the requirements of Section 4.05(b), New York Registry Shares will be delivered. 

  
 24 













 (b) Conversion Procedures. 

(i) To exercise the Voluntary Conversion Right with respect to a Physical Note, the Holder must: 

(A) complete all particulars and properly manually sign the Form of Conversion Notice attached hereto as Exhibit B (the
“Conversion Notice”) or a facsimile of the Conversion Notice; 
 (B) deliver the original Conversion Notice,
which is irrevocable, to the Principal Conversion Agent (with a copy to the Company) and the Note to the Principal Conversion Agent on or prior to 4:00 p.m., New York City time, on the last day of the Conversion Period; and 

(C) if required, furnish appropriate endorsements and transfer documents. 

In its Conversion Notice with respect to a Physical Note, the Holder must specify whether it wishes to receive (i) New York Registry
Shares or (ii) European Registry Shares. If no preference is specified, New York Registry Shares will be delivered. 

(ii) If an owner holds a beneficial interest in a Global Note such owner must comply with the Depository’s procedures for
converting a beneficial interest in a Global Note. 
 (iii) If an owner of a beneficial interest in a Global Note wishes to
receive European Registry Shares (x) upon a mandatory conversion with respect to such interest, upon the exercise of the Voluntary Conversion Right with respect to such interest or at maturity, then either (x) no later than three Business
Days after notice from the Company of a mandatory conversion in the case of a mandatory conversion, (y) upon its exercise of the Voluntary Conversion Right in the case of the exercise of such Voluntary Conversion Right or (z) no later than
three Business Days prior to the Maturity Date, such owner of a beneficial interest in the Global Notes must: 
 (A) complete
all particulars and properly manually sign the Conversion Notice or a facsimile of the Conversion Notice; and 
 (B) deliver
the original Conversion Notice (together with all attachments thereto), which is irrevocable, to the Principal Conversion Agent (with a copy to the Company) on or prior to 4:00 p.m., New York City time. 

  
 25 













 (iv) In the case of Section 4.05(b)(i), Section 4.05(b)(ii) or
Section 4.05(b)(iii), the Conversion Agent and Securities Administrator shall be permitted to request such evidence reasonably satisfactory to it documenting the identity and/or signature of the owner, with such signature guaranteed by an
“eligible guarantor institution” meeting the requirements of the Registrar, which requirements include membership or participation in Securities Transfer Agents Medallion Program (“STAMP”) or such other “signature
guarantee program” as may be determined by the Conversion Agent or Securities Administrator in addition to, or in substitution for, STAMP, all in accordance with the Securities Exchange Act of 1934, as amended. 

In addition, the Securities Administrator must receive (x) DWAC instructions given in accordance with the
Depository’s procedures from an agent member directing the Securities Administrator to reduce the principal amount of the applicable Global Note in an amount equal to the beneficial interest held by such owner in such Global Note and (y) a
written order given in accordance with the Depository’s procedures containing information regarding the participant account of the Depository. The Securities Administrator shall give the Company notice of such instructions no later than the
Business Day after such instructions are received by the Securities Administrator. 
 (v) Upon fulfilment of all requirements
specified in Section 4.05(b)(i), the Principal Conversion Agent shall confirm whether the number of Notes delivered to the Principal Conversion Agent exceeds or falls short of the number of Notes specified in the Conversion Notice. In the event
of any such excess or shortfall, the Holder or owner shall receive the lower of (i) such total number of Settlement Shares which corresponds to the number of Notes set forth in the Conversion Notice, or (ii) such total number of Settlement
Shares which corresponds to the number of Notes in fact delivered. Any Notes delivered in excess of the number of Notes specified in the Conversion Notice will be redelivered to the Holder or owner at its cost. In the case of
Section 4.05(b)(ii) or Section 4.05(b)(iii), the Principal Conversion Agent will act in accordance with the regulations of the Depository in respect of any Global Note. 

(vi) The Holder or owner of a beneficial interest in a Global Note will be deemed the record owner of Settlement Shares as at
5:00 p.m., New York City time, on the applicable Settlement Date. Until such time, such Holder or owner will not be entitled to any of the rights of a record holder of Shares. 

(vii) Upon any Conversion of the Notes, the Settlement Shares to be delivered shall be transferred in accordance with the
procedures of the Depository or to the securities account specified in the Conversion Notice. 
 (c) Issue or Transfer Taxes; Fees.
The Company will pay any documentary, stamp or similar issue or transfer tax due or fees payable to Citibank, N.A. (or its successor) upon delivery of New York Registry Shares or to BNP Paribas Securities Services (or its successor) upon delivery of
European Registry Shares unless any portion of the tax or fee is due because the Holder requests any Settlement Shares to be issued in a name other than the Holder’s name, in which case the Holder will pay that portion of the tax or fee. 

  
 26 













 SECTION 4.06. Conversion Ratio Adjustments.  

(a) If any of the transactions described in this Section 4.06(a) (each, an “Adjustment Event”) occur after the Issue
Date, in each case the Record Date of which falls prior to the relevant Settlement Date, the rights of the Holders will be preserved until the relevant Settlement Date by adjusting each Conversion Ratio on the relevant Adjustment Date in accordance
with this Section 4.06. Any such adjustments shall be calculated by the Calculation Agent. Upon any adjustment to any Conversion Ratio, and with effect from the relevant Adjustment Date, each Conversion Price will be adjusted by multiplying
each Conversion Price in effect immediately prior to such adjustment by a fraction, the numerator of which is the Minimum Conversion Ratio in effect immediately prior to such adjustment to the Conversion Ratio as aforesaid and the denominator of
which is the Minimum Conversion Ratio as so adjusted. In the event of an adjustment carried out pursuant to this Section 4.06(a), each adjusted Conversion Ratio and each Conversion Price will be rounded to the nearest one-hundred thousandth (0.000005 being rounded upwards). Any subsequent adjustments to any Conversion Ratio (or, as the case may be, Conversion Price) will be carried out on the basis of such adjusted Conversion
Ratio (or, as the case may be, Conversion Price) so rounded. Any such adjustments to any Conversion Ratio or Conversion Price will be calculated by the Calculation Agent (unless otherwise specified). 

(i) In the event of a financial transaction conferring to shareholders as a class a preferential subscription right which is
admitted to trading on the Share Stock Exchange, the adjusted Conversion Ratio will be determined by multiplying the Conversion Ratio in effect immediately prior to the relevant Adjustment Date by the following formula: 

Share price ex-subscription right plus the price of the subscription right 

Share price ex-subscription right 

(A) For the purposes of calculating this formula, the “Share price
ex-subscription right” and the “price of the subscription right” will be equal to the arithmetic average of the Share Prices and the Daily VWAPs (on the Share Stock Exchange) of the preferential
subscription right per Share (respectively) on each Trading Day falling on after the relevant Ex-Date and on which the subscription right is so traded. 

(B) In the event of a financial transaction conferring to shareholders as a class a preferential subscription right which is
admitted to trading on any market or exchange other than the Share Stock Exchange, the “price of the subscription right” will be such price as is determined in good faith to be appropriate by an Independent Adviser. 

(ii) In the event of an increase in share capital by capitalization of reserves, profits or share premia which is carried out
by distribution of bonus Shares to shareholders as a class (other than any Cash Dividend as referred to in clause (viii) below), or in the event of a reduction in share capital which is carried out by a reduction in the number of Shares held by
shareholders as a class, or in the event of a Share split or reverse Share split, the adjusted Conversion Ratio will be determined by multiplying the Conversion Ratio in effect immediately prior to the relevant Adjustment Date by the following
formula: 

  
 27 













 Number of Shares outstanding after the transaction 

Number of Shares outstanding before the transaction 

For the avoidance of doubt, in the event of an increase or a decrease in share capital as aforesaid, the rights attached to any Share to be
delivered to Holders upon conversion of the Notes in accordance with the Indenture will be modified accordingly (including without limitation, where the Company has previously assigned a nominal value the Shares and the relevant increase of decrease
in share capital results in an increase of decrease in such nominal value). 
 (iii) In case of a distribution of securities
or assets made out of reserves or of premiums (in each case other than any Cash Dividend as referred to in clause (viii) below) to shareholders as a class, the adjusted Conversion Ratio will be determined by multiplying the Conversion Ratio in
effect immediately prior to the relevant Adjustment Date by the following formula: 
 Value of the Share prior to the date on which the
Shares 

                       
   are traded ex-distribution                         

Value of the Share prior to the date on which the Shares are traded 

ex-distribution minus the value of the securities or assets distributed per Share 

For the purpose of calculating this formula: 

(A) the “value of the Share prior to the date on which the Shares are traded
ex-distribution” will be equal to the arithmetic average of the Share Prices on each of the three consecutive Trading Days ending on (and including) the Trading Day immediately preceding the relevant Ex-Date; 
 (B) the “value of the securities or assets distributed per Share”:

 (1) if such securities or assets are traded on a regulated market in the European Union (or its equivalent in a non-European Union jurisdiction) on each of the three consecutive Trading Days preceding the relevant Ex-Date: will be equal to the arithmetic average of the Daily VWAPs of
such securities or assets per Share on each of the three consecutive Trading Days immediately preceding the relevant Ex-Date; or 

(2) if such securities or assets are not traded on a regulated market in the European Union (or its equivalent in a non-European Union jurisdiction) on each of the three consecutive Trading Days preceding the relevant Ex-Date and: 

  
 28 













 a. if such securities or assets are admitted to trading on a regulated
market in the European Union (or its equivalent in a non-European Union jurisdiction) within 20 Trading Days of the relevant Ex-Date: will be equal to the arithmetic
average of the Daily VWAPs of such securities or assets per Share on each of the first three Trading Days (on which such securities or assets are so traded) comprised in such period of 20 Trading Days as aforesaid commencing on (and including) the
relevant Ex-Date (or, if such securities or assets are not so traded on such Ex-Date, the immediately following Trading Day on which such securities or assets are so
traded), or such lesser number of Trading Days on which such securities or assets are so traded, provided that if such number is less than 2 or if the “value of the securities or assets distributed per Share” cannot be so determined, the
“value of the Share prior to the date on which the Shares are traded ex-distribution” and the “value of the securities or assets distributed per Share” shall be such values as are
determined in good faith to be appropriate by an Independent Adviser; or 
 b. if such securities or assets are not admitted
to trading on a regulated market in the European Union (or its equivalent in a non-European Union jurisdiction) within 20 Trading Days of the relevant Ex-Date: will be
equal to such value as is determined in good faith to be appropriate by an Independent Adviser. 
 (iv) In the event of an
allotment to shareholders as a class of bonus financial instruments of the Company (other than Shares, any preferential subscription rights as referred to in clause (i) above, any distribution as referred to in clause (iii) above or any
Cash Dividend as referred to in clause (viii) below), the adjusted Conversion Ratio will be determined: 
 (A) if the
right to receive such financial instruments is admitted to trading on the Share Stock Exchange within 20 Trading Days of the relevant Ex-Date: by multiplying the Conversion Ratio in effect immediately prior to
the relevant Adjustment Date by the following formula: 
 Share price ex-right plus the
price of the right to receive financial instruments 
 Share price ex-right 

For the purposes of calculating this formula, the “Share price ex-right” and the “price
of the right to receive financial instruments” will be equal to the arithmetic average of the Share Prices and the Daily VWAPs of the right to receive financial instruments per Share (respectively) on each of the three consecutive Trading Days
(on which the right to receive financial instruments is so traded) comprised 

  
 29 













 
in such period of 20 Trading Days as aforesaid commencing on (and including) the relevant Ex-Date (or, if the right to receive financial instruments is not
traded, as described above, on such Ex-Date, the immediately following Trading Day on which such right is so traded), or such lesser number of Trading Days on which such right is so traded, provided that, if
such number is less than 2 or if the “price of the right to receive financial instruments” cannot be so determined, the “Share price ex-right” and the “price of the right to receive
financial instruments” shall be such prices as are determined in good faith to be appropriate by an Independent Adviser. 

(B) if the right to receive financial instruments is not admitted to trading on the Share Stock Exchange within 20 Trading Days
of the relevant Ex-Date: by multiplying the Conversion Ratio in effect immediately prior to the relevant Adjustment Date by the following formula: 

Share price ex-right plus the value of the financial instruments allocated to each Share 

Share price ex-right 

For the purposes of calculating this formula, the “Share price ex-right” and the “value
of the financial instruments allocated to each Share” and: 
 (1) if such instruments are admitted to trading on a
regulated market in the European Union (or its equivalent in a non- European Union jurisdiction) within 20 Trading Days of the relevant Ex-Date: will be equal to the
arithmetic average of the Share Prices and the Daily VWAPs of such instruments per Share (respectively) on each of the three consecutive Trading Days (on which such instruments are so traded) comprised in such period of 20 Trading Days as aforesaid
commencing on (and including) the relevant Ex-Date (or, if such instruments are not traded on such Ex-Date, the immediately following Trading Day on which such
instruments are so traded), or such lesser number of Trading Days on which such instruments are so traded, provided that, if such number is less than two or if such “value of the financial instruments allocated to each Share” cannot be so
determined, the “Share price ex-right” and the “value of the financial instruments allocated to each Share” shall be such values as are determined in good faith to be appropriate by an
Independent Adviser; and 
 (2) if such financial instruments allocated are not traded on a regulated market in the European
Union (or its equivalent in a non-European Union jurisdiction) within 20 Trading Days of the relevant Ex-Date: will be equal to such values as are determined in good
faith to be appropriate by an Independent Adviser. 
 (v) In the case of: 

(A) any recapitalization, reclassification or change of the Shares (other than as referred to in clause (ii) above); 

  
 30 













 (B) any consolidation, merger or combination involving the Company; 

(C) any division (scission) or transfert d’universalité, transfert du patrimoine professionnel
or other spin-off involving the Company; or 
 (D) any sale, lease or other transfer
to a third party of the consolidated assets of the Company and its subsidiaries substantially as an entirety; 
 in each case, as a result of
which Shares would be converted into, or exchanged for, equity instruments, other securities, other property or assets (including cash or any combination thereof), then, at and after the effective time of the transaction, references to the Shares
for purposes of determining the consideration receivable on conversion of Notes will instead refer to the kind and amount of shares of equity instruments, other securities or other property or assets (including cash or any combination thereof) that
a holder of Shares immediately prior to such transaction would have owned or been entitled to receive (the “reference property”) upon such transaction, all as determined in good faith to be appropriate by an Independent Adviser. 

The Company will execute a supplemental indenture in connection with any such transaction providing that the Notes will be convertible into
reference property will also provide for anti-dilution and other adjustments that are as nearly equivalent as possible to the adjustments provided for herein in respect of the Shares. Such supplemental amendment shall, for the avoidance of doubt,
not require any consent by the Holders of Notes. 
 (vi) In the event that the Company makes an offer to shareholders as a
class to buy back its own Shares at a price that is higher than the Market Price the adjusted Conversion Ratio will be determined by multiplying the Conversion Ratio in effect immediately prior to the relevant Adjustment Date by the following
formula: 
 Market Price multiplied by (1 minus Pc percent) 

Market Price minus (Pc percent multiplied by Buy-back Price) 

For the purpose of calculating this formula: 

(A) “Market Price” means the arithmetic average of the Share Prices on each of the 3 consecutive Trading Days ending
on (and including) the last Trading Day on which the Shares are traded cum- the right for the Shares to be tendered into such buyback offer (such last Trading Day as aforesaid, the “Buyback
Reference Date”); 
 (B) “Pc percent” means the percentage of the share capital that has been bought
back; and 

  
 31 













 (C) “Buy-back Price” means
the price per Share at which the Shares are bought back (converted, if necessary, into U.S. dollars at the Prevailing Rate on the Buyback Reference Date). 

(vii) In the event of a modification of allocation of the profits of the Company through issuance of voting or non-voting preference shares or other preferred equity instruments, an Independent Adviser will determine in good faith the fair and reasonable adjustment (if any) to be made to the Conversion Ratio in respect
thereof, taking into account, among other things, the value of the Shares prior to the change in the Company’s profit allocation, the modifications made to the allocation of the profits of the Company, the terms and conditions of the non-voting preference shares or other preferred equity instruments and the terms of the offering of such shares or instruments, provided that if such shares or instruments are offered through preferential
subscription rights or by way of a free allocation, the Conversion Ratio will be adjusted only pursuant to clauses (i) or (iv) above. 

(viii) In the event of a dividend or other distribution to shareholders as a class which is paid in cash (including any
dividend or distribution which is payable either in cash or in kind (including but not limited to Shares) at the option of the shareholders) (any such dividend or distribution, a “Cash Dividend”), the adjusted Conversion
Ratio will be determined by multiplying the Conversion Ratio in effect immediately prior to the relevant Adjustment Date by the following formula: 

        SP         

    SP – D     

where: 
 (A)
“D” means the amount (prior to any withholdings and without taking into account any applicable deductions) of such Cash Dividend per Share (converted, if necessary, in U.S. dollars at the Prevailing Rate on the relevant Ex-Date), provided that in the case of a Cash Dividend which is a dividend or other distribution payable either in cash or in kind (including but not limited to Shares) at the option of the shareholders, the amount
of such Cash Dividend shall be equal to the amount of such cash (prior to any withholdings and without taking into account any applicable deductions) as is payable per Share (i.e. disregarding the value of the
in-kind property payable in lieu of such cash amount at the option of the shareholders as aforesaid); and 

(B) “SP” means the arithmetic average of the Share Prices on each of the three consecutive Trading Days ending on
(and including) the Trading Day immediately preceding the relevant Ex-Date. 

  
 32 













 (b) Whenever the Conversion Ratio is adjusted as herein provided, the Company shall promptly
file with the Securities Administrator and any Conversion Agent an Officer’s Certificate setting forth the Conversion Ratio and the Conversion Price in effect after such adjustment and setting forth a brief statement of the facts requiring such
adjustment. Unless and until a responsible officer of the Trustee, the Securities Administrator or any Conversion Agent shall have received such Officer’s Certificate, the Trustee, the Securities Administrator or such Conversion Agent, as
applicable, shall not be deemed to have knowledge of any adjustment of the Conversion Ratio or the Conversion Price and may assume without inquiry that the last Conversion Ratio and Conversion Price of which it has knowledge is still in effect.
Promptly after delivery of such certificate, and in no event later than 5 Business Days following such delivery, the Company shall prepare a notice of such adjustment of the Conversion Ratio and the Conversion Price setting forth the adjusted
Conversion Ratio and Conversion Price and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Ratio and the Conversion Price to the Trustee, the Securities Administrator and the
Conversion Agent and to each Holder of the Notes. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

(c) For purposes of this Section 4.06 (including without limitation for the purpose of determining the value or amount of any dividend,
distribution or other entitlement on a “per Share” basis), the number of Shares at any time outstanding shall not include Shares held in the treasury of the Company so long as such Shares are not entitled to the relevant dividend,
distribution or other entitlement, but shall include Shares issuable in respect of scrip certificates issued in lieu of fractions of Shares. 

(d) Notwithstanding anything to the contrary in this Section 4.06, no adjustment to the Conversion Ratio shall be made: 

(i) upon the issuance of any Shares pursuant to any present or future plan providing for the reinvestment of dividends or
interest payable on the Company’s securities and the investment of additional optional amounts in Shares under any plan; 

(ii) upon the issuance of any Shares or options or rights to purchase those Shares pursuant to any present or future employee,
director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries; 
 (iii) upon the
issuance of any Shares pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) above and outstanding as of the date the Notes were first issued; or 

(iv) for accrued and unpaid interest on the Notes. 

(e) In the event that the Company carries out any transaction in respect of which an adjustment would not be made as specified in
Section 4.06(a)(i) to (a)(viii) above and if any future law or regulation should provide for an adjustment, the Calculation Agent or, if applicable, Independent Adviser, will make such adjustment in accordance with the applicable laws and
regulations and with the practices used in the markets on which the Notes are traded. 

  
 33 













 (f) If any doubt shall arise as to whether an adjustment falls to be made to the Conversion
Ratio (or, as the case may be, Conversion Price) or as to the appropriate adjustment to the Conversion Ratio (or, as the case may be, Conversion Price), and following consultation between the Company, the Calculation Agent and an Independent
Adviser, a written opinion of such Independent Adviser in respect thereof shall be conclusive and binding on the Company, the Trustee, the Securities Administrator, the Calculation Agent and the Holders, save in the case of manifest error. 

SECTION 4.07. Taxes on Shares Issued. The Company shall pay any documentary, stamp or similar issue or transfer tax due on the
issue or delivery of Shares upon conversion of Notes pursuant hereto; provided, however, that if such documentary, stamp or similar issue or transfer tax is due because the Holder of such Notes has requested that Shares be issued in a
name other than that of the Holder of the Notes converted, then such taxes will be paid by the Holder, and the Company shall not be required to issue or deliver any stock certificate evidencing such Shares unless and until the Holder shall have paid
to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 

SECTION 4.08. Reservation of Shares; Shares to be Fully Paid; Compliance With Governmental Requirements; Listing of Shares. From
and after the time of effectiveness of the Shareholder Resolution, the Company shall reserve, out of its authorized but unissued shares or shares held in treasury, sufficient number of Shares to satisfy early mandatory conversion of the Notes
pursuant to Section 4.01(c). The Settlement Shares will be subject to all provisions of the articles of association of the Company, will be fully fungible with the other existing Shares of the Company and will carry all rights attached to such
Shares as from the relevant Settlement Date, it being understood that, in the event a Record Date should occur before the relevant Settlement Date, Holders will not have the right to receive or to be indemnified for the dividend or any other
distribution or allocation with respect to the Shares related to such Record Date (without prejudice to the right to adjustment of the Conversion Ratio pursuant to Section 4.06). 

The Company covenants that all Settlement Shares shall be duly authorized, validly issued, fully paid and
non-assessable and shall be free from pre-emptive rights and free from any tax, lien or charge (other than those created by the Holder). 

The Company shall list or cause to have quoted any Settlement Shares on each national securities exchange or over-the-counter or other domestic market on which the Shares are then listed or quoted. 
 The
Company shall procure delivery of the Settlement Shares through the applicable Depositary. 
 SECTION 4.09. Inability to Deliver
Settlement Shares. Should the Company become legally barred from delivering or otherwise be unable to deliver Shares upon conversion of the Notes, the rights and claims that the Holders would otherwise have to convert their Notes into Shares
will be suspended for the duration of such inability of the Company to deliver Shares; provided that the Notes will continue to bear interest in accordance with Article 3. Such suspension shall not constitute a default of the Company or any
other breach of obligations under the Notes (without prejudice to Holders’ rights pursuant to Section 5.02(a)) and shall not affect any other claim or right of the Holders pursuant to the Notes and the Indenture. 

  
 34 













 If as a result of an event described in Section 5.03 having occurred in relation to the
Company, the Company is unable to deliver Settlement Shares to the Holders, the claims of each Holder against the Company for the delivery of Settlement Shares will be converted into a subordinated monetary claim against the Company equal to the
Redemption Amount per Note. 
 The Redemption Amount will be determined by the Calculation Agent. No interest will be payable with respect
to the Redemption Amount. The Redemption Amount will fall due for payment not later than on the Business Day prior to the day on which the event described in Section 5.03 occurs. 

SECTION 4.10. Limited Responsibility of Trustee, Securities Administrator and Conversion Agent. The Trustee, the Securities
Administrator and any Conversion Agent, or any of their respective agents, shall not at any time be under any duty or responsibility to any Holder to determine or calculate the Conversion Ratio, to determine whether any facts exist which may require
any adjustment of the Conversion Ratio, or to confirm the accuracy of any such adjustment when made or the appropriateness of the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee,
the Securities Administrator and any other Conversion Agent, or any of their respective agents, shall not be accountable with respect to the validity or value (or the kind or amount) of any Shares or of any other securities or property that may at
any time be issued or delivered upon the conversion of any Notes; and the Trustee, the Securities Administrator and the Conversion Agent make no representations with respect thereto. None of the Trustee, the Securities Administrator nor any
Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any Shares or stock certificates or other securities or property or cash upon the surrender of any Notes for the purpose of conversion or to comply
with any of the duties, responsibilities or covenants of the Company contained in the Indenture. The rights, privileges, protections, immunities and benefits given to the Securities Administrator, including without limitation its right to be
compensated, reimbursed, and indemnified, are extended to, and shall be enforceable by, the Securities Administrator in each of its capacities hereunder, including its capacity as Conversion Agent. This provision shall survive the termination of the
Indenture. 
 SECTION 4.11. Limited Responsibility of Calculation Agent and Independent Adviser. The Calculation
Agent (and any Independent Adviser appointed in connection with the Notes) is acting exclusively as an agent for, and upon request from, the Company. Neither the Calculation Agent (acting in such capacity) nor any Independent Adviser appointed in
connection with the Notes (acting in such capacity), shall have any relationship of agency or trust with, nor shall the Calculation Agent (acting in such capacity) nor any Independent Adviser appointed as aforesaid shall (to the fullest extent
permissible by law) be liable nor shall they incur any liability as against, the Holders, the Trustee or the Securities Administrator. The Calculation Agent may, subject to the provisions of the calculation agency agreement to be entered into
between the Company and the Calculation Agent at the latest on the Issue Date, consult on any matter (including but not limited to, any legal matter), with any legal or other professional adviser and it shall be able to rely upon, and it shall not
be liable and shall incur no liability as against the Company, the Holders, the Trustee or the Securities Administrator in respect of anything done, or omitted to be done, relating to that matter in good faith in accordance with that adviser’s
opinion. Notwithstanding the foregoing, this provision shall (subject to the provisions of the calculation agency agreement) not relieve the Calculation Agent of liability to the Company for wilful misconduct, fraud or gross negligence, however.
This provision shall survive the termination of the Indenture. 

  
 35 













 SECTION 4.12. Stockholder Rights Plan. Each Settlement Share issued upon
conversion of Notes pursuant to this Article 4 shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Shares issued upon such conversion shall bear such legends, if any, in each case as may be
provided by the terms of any stockholder rights plan adopted by the Company, as the same may be amended from time to time if such rights have not separated from the Shares or become exercisable (in which event, no adjustment will be made in respect
of such rights pursuant to Section 4.06(a)(iv) above). Notwithstanding the foregoing, if prior to any conversion such rights have separated from the Shares in accordance with the provisions of the applicable stockholder rights agreement, the
Conversion Ratio shall be adjusted at the time of separation as if the Company had distributed to all holders of the Shares rights as described in Section 4.06(a)(iv) above. 

SECTION 4.13. Notice of Source of Shares. Within a commercially reasonable period of time following the first general meeting of
shareholders of the Company following the Issue Date, the Company shall publish on the Company’s website, or through such other public medium as the Company may use at such time, the outcome of the vote of the on the resolution to enable the
issuance of new Shares to satisfy the Company’s obligation with such new Shares upon conversion of the Notes. 
 ARTICLE 5 

REMEDIES 

SECTION 5.01. Applicability of Article V of the Base Indenture. The provisions set forth in this Article 5, with respect to the
Notes, supersede in its entirety Article V of the Base Indenture, and all references in the Base Indenture to Article V thereof and defaults and remedies provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be
references to this Article 5 and the provisions set forth in this Article 5, respectively; provided, however, that the provisions in Article V of the Base Indenture providing for the collection of fees, expenses and indemnities by the
Trustee, the Securities Administrator or any other Agents shall not be deemed to be superseded hereby. 
 SECTION 5.02. Enforcement
Events. (a) If a Non-payment Event occurs, then the Trustee, on behalf of the Holders of the Notes, may, at its discretion, or shall at the direction of Holders of 25% of the aggregate principal
amount of outstanding Notes, subject to any applicable laws, institute proceedings for the bankruptcy of the Company and/or prove in any bankruptcy (or other insolvency proceedings) of the Company in respect of any payment or delivery, as the case
may be, obligations of the Company arising under the Notes, but may take no other action in respect of such Non-payment Event. 

(b) If a Bankruptcy, Dissolution or Liquidation Event occurs, each Holder will be entitled to declare its Notes due and demand immediate
redemption thereof at the Redemption Amount, together with accrued and unpaid interest, if any, to the date of repayment and Optionally Outstanding Payments, if any. 

  
 36 













 (c) Neither the Trustee nor any Holder may take any action other than pursuant to clause
(a) or (b) above in respect of an Enforcement Event, and in particular may not take any other action that would influence the outcome of a bankruptcy proceeding or restructuring outside bankruptcy. In addition, following a judgment for
bankruptcy, dissolution or liquidation of the Company, if such judgment that would otherwise constitute an Enforcement Event is overturned on appeal or otherwise validly nullified, then such judgment will be deemed to have never constituted an
Enforcement Event and the Notes will be deemed to have not become due and repayable as a result thereof. 
 SECTION 5.03.
Termination Rights of the Holders. Each Holder will be entitled to declare its Notes due and demand immediate redemption thereof at the Redemption Amount, together with accrued interest, if any, to the date of repayment and Optionally
Outstanding Payments, if any, in the event that the Company goes into liquidation unless this is done in connection with a merger, or other form of combination with another company and such company assumes all obligations contracted by the Company
in connection with the Notes. 
 Any notice, including any notice declaring Notes due, in accordance with the above will be made by means of
a written declaration in the English language delivered by hand or registered mail to the specified officer of the Principal Paying Agent together with proof that such Holder at the time of such notice is a Holder of the relevant Notes by means of a
certificate of its Custodian or in other appropriate manner. The Principal Paying Agent shall promptly provide notice to the Company of its receipt of any such notice of declaration. 

If any Note is declared due for early redemption by Holders pursuant to the provisions described in this Section 5.03, the Voluntary
Conversion Right pursuant to Section 4.03 in respect of such Note may no longer be exercised by such Holder from the time of receipt of the notice of termination by the Principal Paying Agent pursuant to the immediately preceding sentence. 

ARTICLE 6 
 SATISFACTION
AND DISCHARGE 
 SECTION 6.01. Satisfaction and Discharge of the Second Supplemental Indenture. (a) The satisfaction
and discharge provisions set forth in this Article 6 shall, with respect to the Notes, supersede in its entirety Article XII of the Base Indenture, and all references in the Base Indenture to Article XII thereof and satisfaction and discharge
provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 6 and the satisfaction and discharge provisions set forth in this Article 6, respectively. When (i) the Company shall deliver
to the Security Registrar for cancellation all Notes theretofore authenticated (other than any Notes that have been destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) and
not theretofore canceled, or (ii) all the Notes not theretofore canceled or delivered to the Securities Administrator for cancellation shall have become due and payable (whether at the Maturity Date or upon early conversion, redemption or
otherwise) and the Company shall deposit with the Securities Administrator, in trust, or deliver to the Holders, as applicable, cash funds or Shares, as applicable, sufficient to pay all amounts due (and Shares deliverable following conversion, if
applicable) on all of such Notes (other than any Notes that shall have been mutilated, destroyed, 

  
 37 













 
lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) not theretofore canceled or delivered to the Securities Administrator for
cancellation, including principal and interest due, accompanied by a verification report as to the sufficiency of the deposited amount from an independent certified accountant or other financial professional reasonably satisfactory to the Securities
Administrator (which may include any of the Underwriters), and, in the case of (i) or (ii) above, if the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Second Supplemental Indenture shall
cease to be of further effect (except as to (A) rights hereunder of Holders of the Notes to receive all amounts owing upon the Notes and the other rights, duties and obligations of Holders of the Notes, as beneficiaries hereof with respect to
the amounts, if any, so deposited with the Securities Administrator and (B) the rights, obligations and immunities of the Trustee, the Securities Administrator and the Agents hereunder), and the Trustee and the Securities Administrator, on
written demand of the Company accompanied by an Officer’s Certificate and an Opinion of Counsel as required by Section 1.02 of the Base Indenture and at the cost and expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Second Supplemental Indenture; the Company, however, hereby agrees to reimburse the Trustee and the Securities Administrator for any costs or expenses thereafter reasonably and properly incurred by the Trustee or
the Securities Administrator, including the fees and expenses of their counsel, and to compensate the Trustee and the Securities Administrator for any services thereafter reasonably and properly rendered by the Trustee or the Securities
Administrator in connection with this Second Supplemental Indenture or the Notes. 
 SECTION 6.02. Deposited Monies to Be Held in
Trust by Securities Administrator. Subject to Section 6.04, all monies deposited with the Securities Administrator pursuant to Section 6.01 shall be held in trust for the sole benefit of the Holders of the Notes, and such monies shall
be applied by the Securities Administrator to the payment, either directly or through any Paying Agent (including the Company if acting as its own Paying Agent), to Persons entitled thereto and to the Holders of the particular Notes for the payment
or redemption of which such monies have been deposited with the Securities Administrator, of all sums due and to become due thereon for principal and interest, if any. 

SECTION 6.03. Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of this Second Supplemental Indenture, all
monies then held by any Paying Agent (if other than the Securities Administrator) shall, upon written request of the Company, be repaid to it or paid to the Securities Administrator, and thereupon such Paying Agent shall be released from all further
liability with respect to such monies. 
 SECTION 6.04. Return of Unclaimed Monies. Subject to the requirements of applicable
law, any monies deposited with or paid to the Securities Administrator for payment of amounts due on the Notes and not applied but remaining unclaimed by the Holders of the Notes for two years after the date upon which the principal of or interest,
if any, on such Notes, as the case may be, shall have become due and payable, shall be repaid to the Company by the Securities Administrator on demand, and all liability of the Securities Administrator shall thereupon cease with respect to such
monies; and the Holder of any of the Notes shall thereafter look only to the Company for any payment that such Holder of the Notes may be entitled to collect unless an applicable abandoned property law designates another Person. 

  
 38 













 SECTION 6.05. Reinstatement. If the Securities Administrator or the Paying Agent
is unable to apply any money in accordance with Section 6.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under the
Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 6.01 until such time as the Securities Administrator or the Paying Agent is permitted to apply all such money in accordance with
Section 6.02; provided, however, that if the Company makes any payment of interest on or principal of any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such
Notes to receive such payment from the money held by the Securities Administrator or Paying Agent. 
 ARTICLE 7

Administrator may amend the Notes and the Indenture with respect to the Notes as provided in Sections 9.01 and 9.02 of the Base Indenture. Notwithstanding the foregoing provision and in addition to the provisions of Section 9.02 of the Base
Indenture, without the consent of each Holder of an outstanding Note affected thereby, no amendment or waiver may: 
 (a) make any change
that adversely affects the conversion rights of any of the Notes; 
 or 

(b) reduce the Redemption Amount of any Note or amend or modify in any manner adverse to the Holders the Company’s obligation to make such
redemption, whether through an amendment or waiver of provisions in the covenants, definitions related thereto or otherwise. 

SECTION 7.03. Holders Approval of Amendments. The consent of the Holders is not necessary under the Indenture to approve the
particular form of any proposed amendment, supplement or waiver, but it will be sufficient if such consent approves the substance of such proposed amendment, supplement or waiver. After an amendment, supplement or waiver becomes effective, the
Company shall give to the Holders affected by such amendment, supplement or waiver a notice in accordance with the Indenture briefly describing such amendment, supplement or waiver. The Company shall mail supplemental indentures to Holders upon
request. Any failure of the Company to mail such notice, or any defect in such notice, will not, however, in any way impair or affect the validity of any such supplemental indenture or waiver. 

  
 39 













 SECTION 7.04. Execution of Second Supplemental Indenture. In executing this
Second Supplemental Indenture and any amendments or supplements thereto, each of the Trustee and the Securities Administrator shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel stating that the
execution of this Second Supplemental Indenture is authorized or permitted by the Indenture, and that this Second Supplemental Indenture, when executed and delivered by the Company, will constitute a valid and binding obligation of the Company
enforceable in accordance with its terms. Each of the Trustee and the Securities Administrator may, but shall not be obligated to, enter into any such supplemental indenture which affects its own rights, duties or immunities under this Second
Supplemental Indenture, the Indenture or otherwise. 
 ARTICLE 8 

CONSOLIDATION, MERGER, CONVEYANCE OR TRANSFER 

SECTION 8.01. Applicability of Article VIII of the Base Indenture. The provisions set forth in this Article 8, with respect to the
Notes, supersede in its entirety Article VIII of the Base Indenture, and all references in the Base Indenture to Article VIII thereof and the consolidation, merger, conveyance and transfer provisions therein, as the case may be, shall, with respect
to the Notes, be deemed to be references to this Article 8 and the provisions set forth in this Article 8, respectively. 

SECTION 8.02. Company May Consolidate, Merge, Etc. on Certain Terms. So long as any of the Notes are outstanding, the Company
shall not consolidate with or merge into any other Person (excluding Persons controlled by one or more members of the Mittal Family) or convey or transfer all or substantially all of its properties and assets to any other Person (excluding Persons
controlled by one or more members of the Mittal Family) unless thereafter: 
 (a) the Person formed by such consolidation or into which the
Company is merged, or the Person which acquired all or substantially all of the Company’s properties and assets (the “Successor Company”), expressly assumes pursuant to a supplemental indenture as provided for in the Indenture
the due and punctual payment of interest on and delivery of the consideration due upon conversion of the Notes and the performance or observance of every covenant of the Indenture on the Company’s part to be performed or observed; 

(b) immediately after giving effect to such transaction, no Enforcement Event has occurred and is continuing; and 

(c) the Successor Company delivers to the Trustee and the Securities Administrator an Officer’s Certificate and an Opinion of Counsel of
recognized standing, each stating that the consolidation, merger, conveyance or transfer and the supplemental indenture referenced in clause (a) above comply with the Indenture and that all conditions precedent in the Indenture relating to the
transaction have been complied with and, immediately after giving effect to the transaction, no Enforcement Event has occurred and is continuing, except that such Officer’s Certificate and Opinion of Counsel will not be required in the event
that any such consolidation, merger, conveyance or transfer is made by any court or tribunal having jurisdiction over the Company, its properties and its assets. 

  
 40 













 For purposes of this Section 8.02, the conveyance or transfer of all or substantially
all of the properties and assets of one or more Subsidiaries of the Company to another Person (excluding Persons controlled by one or more members of the Mittal Family), which properties and assets, if held by the Company instead of such
Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the conveyance or transfer of all or substantially all of the properties and assets of the Company to
such Person. 
 SECTION 8.03. Successor Company to Be Substituted. In case of any such consolidation, merger, conveyance or
transfer pursuant to Section 8.02, such Successor Company (if not the Company) shall succeed to and shall be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company
thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Securities
Administrator; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in the Indenture prescribed, the Securities Administrator shall authenticate and shall deliver, or cause to
be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Securities Administrator for authentication, and any Notes that such Successor Company thereafter shall cause to be
signed and delivered to the Securities Administrator for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under the Indenture as the Notes theretofore or thereafter issued in accordance with the terms
of the Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, conveyance or transfer, upon compliance with this Article 8 the Person named as the “Company”
in the first paragraph of this Second Supplemental Indenture (or any successor that shall thereafter have become such in the manner prescribed in this Article 8) may be dissolved, wound up and liquidated at any time thereafter and such Person shall
be released from its liabilities as obligor and maker of the Notes and from its obligations under the Indenture and the Notes. 
 In case of
any such consolidation, merger, conveyance or transfer, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate. 

ARTICLE 9 
 COVENANTS

Furthermore, the Company is entitled to terminate the appointment of any such Agent. In the event of such termination or such Agent being unable or unwilling to continue to act as such an

SECTION 11.05. Payments on Business Days. In any case where any Interest Payment Date or Mandatory Interest Payment Date shall not
be a Business Day at any Place of Payment, then (notwithstanding any other provision of the Indenture or of the Notes) payment of interest need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest Payment Date or Mandatory Interest Payment Date, provided that no interest shall accrue on the amount so payable for the period from and after such Interest

Supplemental Indenture, (i) the Calculation Agent (pursuant to and subject to the provisions of the calculation agency agreement) or, where applicable, an Independent Adviser, shall be responsible for making all calculations (including, without
limitation, in connection with a conversion or redemption of the Notes) specified to be made by the Calculation Agent or Independent Adviser, respectively, in the Indenture and shall make such calculations available to the Company and (ii) the
Company shall be responsible for making any other calculations called for under the Notes. The Company, Calculation Agent or Independent Adviser, as the case may be, shall make all these calculations in good faith and, absent manifest error, the

 SECTION 11.13. Electronic Signatures and Transmission. 

(a) For purposes of this Second Supplemental Indenture, any reference to “written” or “in writing” means any form of
written communication, including, without limitation, electronic signatures, and any such written communication may be transmitted by Electronic Transmission. “Electronic Transmission” means any form of communication not directly involving
the physical transmission of paper, including the use of, or participation in, one or more electronic networks or databases (including one or more distributed electronic networks or databases), that creates a record that may be retained, retrieved
and reviewed by a recipient thereof and that may be directly reproduced in paper form by such a recipient through an automated process. Each of the Trustee and the Securities Administrator is authorized to accept written instructions, directions,
reports, notices or other communications delivered by Electronic Transmission and shall not have any duty or obligation to verify or confirm that the Person sending instructions, directions, 

  
 44 













 
reports, notices or other communications or information by Electronic Transmission is, in fact, a Person authorized to give such instructions, directions, reports, notices or other communications
or information on behalf of the party purporting to send such Electronic Transmission; and neither the Trustee nor the Securities Administrator shall have any liability for any losses, liabilities, costs or expenses incurred or sustained by any
party as a result of such reliance upon or compliance with such instructions, directions, reports, notices or other communications or information to the Trustee or the Securities Administrator, including, without limitation, the risk of the Trustee
or the Securities Administrator acting on unauthorized instructions, notices, reports or other communications or information, and the risk of interception and misuse by third parties. 

(b) Any requirement in this Second Supplemental Indenture or the Notes that a document, including the Notes, is to be signed or authenticated
by “manual signature” or similar language shall not be deemed to prohibit signature to be by facsimile or electronic signature and shall not be deemed to prohibit delivery thereof by Electronic Transmission.

 CUSIP No. 03938L302 

ArcelorMittal, a société anonyme incorporated under the laws of the Grand Duchy of Luxembourg (herein called the
“Company”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises, in lieu of payment of the principal amount [as set forth in the “Schedule of Increases and
Decreases of Notes” attached hereto]3 [of $[
                    ]]4, to deliver, in respect of such principal
amount, to [CEDE & Co.]5 [                     ]6, or registered assigns, on May 18, 2023 with respect to each $25 principal amount, as provided in the Second Supplemental Indenture, a number of Shares equal to the Relevant Conversion Ratio
unless earlier converted, and to pay interest thereon as set forth in the manner, at the rates and to the Persons set forth in the Indenture. 

This Note shall bear interest at a rate of 5.50% per annum from [________________] or from the most recent date to which interest had been
paid or provided to, but excluding, the next scheduled Interest Payment Date, until the principal hereof shall be repaid. Interest on this Note will be computed on the basis of a 360-day year composed of
twelve 30-day months. Interest is payable quarterly in arrears on each February 18, May 18, August 18 and November 18 of each year, commencing on [________________], to the Person in whose
name this Note (or one or more predecessor securities) is registered at the close of business on the Regular Record Date for such interest. 

Interest shall be due and payable on each Interest Payment Date unless the Company elects not to pay such interest on such Interest Payment
Date (which the Company may elect to do on any Interest Payment Date unless such Interest Payment Date is a Mandatory Interest Payment Date). Any such election not to pay interest shall not constitute a default of the Company, an Enforcement Event
or any other breach of obligations under the Indenture or the Notes or for any other purpose. If the Company decides not to pay the interest on an Interest Payment Date, the Company shall notify the Agents and the Holders not less than ten and not
more than 15 Business Days prior to the relevant Interest Payment Date. 
 Any interest not paid because of such an election of the Company
shall constitute Optionally Deferred Payments, which shall themselves bear interest at the Stated Interest Rate. Additional Interest shall accrue from the Interest Payment Date on which such amounts were initially deferred, and shall compound on
subsequent Interest Payment Dates, quarterly, at the Stated Interest Rate.

 The nominal amount of any Optionally Deferred Payments together with any Additional Interest
Amount shall constitute Optionally Outstanding Payments. 
 The Company shall wire, through the facilities of the Securities Administrator,
any payments on any Global Note in immediately available funds to the Depository or its nominee, as the case may be, as the registered Holder of such Global Note. The Company has initially designated the Securities Administrator as the Principal
Paying Agent and Security Registrar in respect of the Notes and its agency at its applicable Corporate Trust Office as a place where Notes may be presented for payment or for registration of transfer. 

This Note constitutes the direct, subordinated and unsecured obligation of the Company and will rank at all times pari passu without
any preference or priority among the Notes and (subject to such exceptions as are from time to time mandatory under Luxembourg law) rank (i) in priority only to the rights and claims against the Company of the holders of Junior Securities;
(ii) pari passu with the rights and claims against the Company of the holders of any Parity Securities; and (iii) junior to the rights and claims against the Company of all Senior Creditors. 

Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place. 
 In the case of any conflict between this Note and the Indenture, the

 [FORM OF REVERSE OF NOTE] 

ARCELORMITTAL 
 5.50% Mandatorily
Convertible Subordinated Note due 2023 
 This Note is one of a duly authorized issue of Securities of the Company (herein called the
“Notes”), initially limited to the aggregate principal amount of $1,250,000,000, or 50,000,000 Notes of $25 principal amount each, all issued or to be issued under and pursuant to an Indenture dated as of January 16, 2013, as
amended and supplemented from time to time in accordance with the terms thereof (herein called the “Base Indenture”) and as further supplemented and amended by the Second Supplemental Indenture dated as of May 18, 2020 (herein
called the “Second Supplemental Indenture” and the Base Indenture, as supplemented and amended by the Second Supplemental Indenture, the “Indenture”) by and among the Company, Wilmington Trust, National Association,
herein called the “Trustee”, and Citibank, N.A., herein called the “Securities Administrator”, and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties
and immunities thereunder of the Company, the Trustee, the Securities Administrator and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. Additional Notes may be issued in an unlimited
aggregate principal amount, subject to certain conditions specified in the Indenture. 
 The provisions in Article 6 of the Second
Supplemental Indenture supersede the entirety of Article XII of the Base Indenture. The provisions of Article 8 of the Second Supplemental Indenture supersede the entirety of Article VIII of the Base Indenture. The provisions of Article IV of the
Base Indenture shall not apply to this Note. 
 The Notes will only be redeemable by conversion into Shares and will not be redeemable in
cash, except upon the occurrence of an Enforcement Event or if the Shareholder Resolution is not passed by July 28, 2020. Each Note not converted, or purchased and cancelled, will be mandatorily converted on the Maturity Date into a number of
Shares equal to the Relevant Conversion Ratio. On the Settlement Date, the Company shall, in addition, pay any Optionally Outstanding Payments and any other accrued and unpaid interest to, but excluding, the Settlement Date. 

Upon the occurrence of an Accelerated Mandatory Conversion Event prior to the 25th Trading Day immediately preceding the Maturity Date, the
Company shall notify the Holders, the Trustee and the Securities Administrator in accordance with the Indenture, and each $25 principal amount of outstanding Notes will be mandatorily converted into Shares at the then prevailing Maximum Conversion
Ratio. On the related Settlement Date, the Company shall, in addition, pay the Make-whole Amount, any Optionally Outstanding Payments and any other accrued and unpaid interest to, but excluding, the Settlement Date. 

As provided in and subject to the provisions of the Indenture, the Company may, at any time during the Conversion Period, mandatorily convert
the outstanding Notes, in whole but not in part, on the Optional Mandatory Conversion Date at the then prevailing Maximum Conversion Ratio for each $25 principal amount of Notes. On the related Settlement Date the Company shall, in addition, pay the
Make-whole Amount, any Optionally Outstanding Payments and any other accrued and unpaid interest to, but excluding, the Settlement Date. 

  
 A-6 













 As provided in and subject to the provisions of the Indenture, the Holder hereof has the
right to convert each of its Notes in whole or in part on any Business Day during the Conversion Period into a number of Settlement Shares equal to the Minimum Conversion Ratio. On the related Settlement Date, the Company shall, in addition, pay any
Optionally Outstanding Payments in respect of the Notes being converted. Accrued and unpaid interest from, and including, the preceding Interest Payment Date, if any, to, but excluding, the conversion date will be deemed to have been paid in full
rather than canceled, extinguished or forfeited. 
 Following a Relevant Event, the Holder hereof has the right to exercise its Voluntary
Conversion Right during the relevant Special Voluntary Conversion Period and convert each of its Notes in whole or in part into Settlement Shares at the Relevant Event Conversion Ratio. On the related Settlement Date, the Company shall, in addition,
pay the Make-whole Amount, any Optionally Outstanding Payments and any other accrued and unpaid interest to, but excluding, the Settlement Date, in each case in respect of the Notes being converted. 

Fractions of Settlement Shares for the aggregate number of Notes of a Holder converted pursuant to the Indenture shall be aggregated, and the
result of such aggregation will be rounded down to the next full Settlement Share. Any remaining fraction of a Settlement Share will not be delivered and will not be compensated in cash. The number of Settlement Shares to be delivered to the
relevant holder of the Notes will be determined as provided above by the Calculation Agent. 
 The Company shall pay any cash amounts due in
money of the United States that at the time of payment is legal tender for payment of public and private debts. 
 The Indenture permits,
with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders to be effected under the Indenture at any time by the Company, the Trustee and the
Securities Administrator with the consent of the Holders of a majority in principal amount of the Notes at the time outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes
at the time outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Note. 
 If a Non-payment Event occurs, then the Trustee, on
behalf of the Holders of the Notes, may, at its discretion, or shall at the direction of Holders of 25% of the aggregate principal amount of outstanding Notes, subject to any applicable laws, institute proceedings for the bankruptcy of the Company
and/or prove in any bankruptcy (or other insolvency proceedings) of the Company in respect of any payment or delivery, as the case may be, obligations of the Company arising under the Notes, but may take no other action in respect of such Non-payment 

  
 A-7 













 
Event. If a Bankruptcy, Dissolution or Liquidation Event occurs, the Holder hereof will be entitled to declare its Notes due and demand immediate redemption thereof at the Redemption Amount,
together with accrued and unpaid interest, if any, to the date of repayment and Optionally Outstanding Payments, if any. Neither the Trustee nor any Holder may take any action other than pursuant to the immediately preceding two sentences in respect
of an Enforcement Event, and in particular may not take any other action that would influence the outcome of a bankruptcy proceeding or restructuring outside bankruptcy. In addition, following a judgment for bankruptcy, dissolution or liquidation of
the Company, if such judgment that would otherwise constitute an Enforcement Event is overturned on appeal or otherwise validly nullified, then such judgment will be deemed to have never constituted an Enforcement Event and the Notes will be deemed
to have not become due and repayable as a result thereof. 
 No reference herein to the Indenture and no provision of this Note or of the
Indenture shall alter or impair the obligations of the Company, which are absolute and unconditional, to deliver Settlement Shares upon conversion of the Notes and to pay the interest on this Note at the time, place and rate, and in the coin and
currency, herein prescribed. 
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note
is registrable in the Security Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Note are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Notes are
issuable only in registered form without coupons in denominations of $25 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal
amount of Notes and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 
 No service
charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee, the Securities Administrator and any agent of
the Company, the Trustee or the Securities Administrator may treat the Person in whose name the Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee, the Securities
Administrator nor any such agent shall be affected by notice to the contrary. 
 All defined terms used in this Note that are defined in the
Indenture shall have the meanings assigned to them in the Indenture.
