THE NOTES 
 Section 3.01. Designation of Notes. This First Supplemental Indenture provides for a series of Securities titled “7.875% Senior Convertible Notes due 2042” of the Company.

  
 7 

 Section 3.02. Ranking; Senior Securities. The Notes shall be senior unsecured
Securities. 
 Section 3.03. Amount. The Trustee shall initially authenticate and deliver up to $56,500,000
aggregate principal amount of the Notes upon a Company Order for the authentication and delivery of Notes, without any further action by the Company. The Company may, without the consent of the Holders of the Notes, upon a Company Order issue
additional Notes (“Additional Notes”) under the Indenture with the same terms as the Notes initially issued as of the date of this First Supplemental Indenture (the “Initial Notes”) in an unlimited principal amount,
provided that if any such Additional Notes are not fungible with the Initial Notes issued under the Indenture for U.S. federal income tax purposes, such Additional Notes shall have a separate CUSIP number, and such Additional Notes will have
a different issue date and may have a different issue price. The Initial Notes and any Additional Notes will be treated as a single series of Securities for all purposes under the Indenture. 

Section 3.04. Stated Maturity. The Notes shall mature on September 1, 2042 unless earlier converted, redeemed or
repurchased in accordance with the provisions hereof. 
 Section 3.05. Interest. Interest on the Notes shall accrue
from the most recent date on which interest has been paid or if no interest has been paid, from August 21, 2012, until the principal thereof is paid or made available for payment. Interest shall be payable semiannually in arrears on
March 1 and September 1 in each year, commencing March 1, 2013. A Holder of any Note at 5:00 p.m., New York City time, on a Regular Record Date shall be entitled to receive interest, on such Note on the corresponding Interest Payment
Date, notwithstanding the conversion of such Notes at any time after 5:00 p.m., New York City time, on such Regular Record Date; provided, however, that at Stated Maturity, the Company will pay accrued interest to the Person to whom the Company pays
the principal amount, regardless of whether such Person is the Holder of record. Notes surrendered for conversion during the period after 5:00 p.m., New York City time, on any Regular Record Date to 9:00 a.m., New York City time, on the
corresponding Interest Payment Date must be accompanied by payment of an amount equal to the interest payable on such Notes. Notwithstanding the foregoing, no such payment of interest need be made by any converting Holder (a) if the Company has
specified a Redemption Date, Mandatory Conversion Date or a Termination of Trading Purchase Date that is after a Regular Record Date and on or prior to the Business Day following the corresponding Interest Payment Date, (b) to the extent of any
overdue interest existing at the time of conversion of such Note or (c) if the Notes are surrendered for conversion after 5:00 p.m., New York City time, on the Regular Record Date immediately preceding a Purchase Date or the Stated Maturity and
before 5:00 p.m., New York City time, on the Business Day immediately preceding a Purchase Date or the Stated Maturity for the Notes. Except as described above, no interest on converted Notes will be payable by the Company on any Interest Payment
Date subsequent to the date of conversion, and delivery of Ordinary Shares or the combination of cash and Ordinary Shares, if applicable, pursuant to Article 11 hereunder, together with any cash payment for any fractional share, upon conversion will
be deemed to satisfy in full the Company’s obligation to pay the principal amount of (and premium, if any, on) the Notes and accrued and unpaid interest to, but not including, the related Conversion Date. The Company shall pay interest upon any
overdue principal and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of accrued and unpaid interest at the rate borne by the Notes from the required payment date.

 (a) Except as otherwise provided pursuant to this Section 3.07, the Notes are issuable in fully registered form without coupons in substantially the form of Exhibit A hereto, with such applicable
legends as are provided for in Section 3.08. The Notes are not issuable in bearer form. The terms and provisions contained in the form of Note shall constitute, and are hereby expressly made, a part of this First Supplemental Indenture and to
the extent applicable, the Company and the Trustee, by their execution and delivery of the Indenture, expressly agree to such terms and provisions and to be bound thereby. Any of the Notes may have such letters, numbers or other marks of
identification and such notations, legends and endorsements as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of the Indenture, or as may be
required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or to conform
to usage. 
 (b) The Notes shall be issued initially as Global Securities in the form of one or more permanent Global Notes,
with the applicable legends as provided in Section 3.08. Each Global Note shall be duly executed by the Company and authenticated and delivered by the Trustee, and shall be registered in the name of DTC, which shall act as Depositary for the
Notes, or its nominee and retained by the Trustee, as Securities Custodian, at its corporate trust office, for credit to the accounts of the Agent Members holding the Notes evidenced thereby. The aggregate principal amount of the Global Notes may
from time to time be increased or decreased by adjustments made on the records of the Trustee, as Securities Custodian, and of DTC or its nominee, as hereinafter provided.

 Section 3.08. Legends. 

(a) In lieu of the Global Security legend set forth in Section 2.14 of the Base Indenture each Global Note issued hereunder shall
bear the following legend (the “Global Note Legend”) on the face thereof: 
 “UNLESS THIS CERTIFICATE IS
PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), NEW YORK, NEW YORK, TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS
REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF
DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. 

TRANSFERS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR
SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO IN THE TERMS OF NOTES ATTACHED HERETO.” 

(b) Legend for Definitive Notes. Definitive Notes will bear a legend substantially in the following form: 

“THIS NOTE WILL NOT BE ACCEPTED IN EXCHANGE FOR A BENEFICIAL INTEREST IN A GLOBAL NOTE UNLESS THE HOLDER OF THIS NOTE, SUBSEQUENT TO
SUCH EXCHANGE, WILL HOLD NO NOTES.” 
 Section 3.09. Book-Entry Provisions for the Global Notes. (a) The
Global Notes initially shall: 
  

	 	(i)	be registered in the name of DTC (or a nominee thereof); 

  

	 	(ii)	be delivered to the Trustee as Securities Custodian; and 

  

	 	(iii)	bear the Global Note Legend set forth in Section 3.08(a). 

 Members of, or participants in, DTC (“Agent Members”) shall have no rights under the Indenture with respect to any Global Note held on their behalf by DTC, or the Trustee as its
custodian, or under such Global Note, and DTC may be treated by the Company, the Trustee and any agent of the Company, or the Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing
contained herein shall prevent the Company, the Trustee or any agent of the Company, or Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or impair, as between DTC and the Agent Members, the
operation of customary practices governing the exercise of the rights of a Holder of any Note. 

  
 10 

 (b) The Holder of a Global Note may grant proxies and otherwise authorize any Person,
including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under the Indenture or the Notes. 
 (c) A Global Note may not be transferred, in whole or in part, to any Person other than DTC (or a nominee thereof) or to a successor thereof (or such successor’s nominee), and no such transfer to any
such other Person may be registered. Beneficial interests in a Global Note may be transferred in accordance with the rules and procedures of DTC. 
 (d) If at any time: 
 (i) DTC notifies the Company in writing that
it is unwilling or unable to continue to act as depositary for the Global Notes and a successor depositary for the Global Notes is not appointed by the Company within 90 days after such notice; 

(ii) DTC ceases to be registered as a “clearing agency” under the Exchange Act and a successor depositary for
the Global Notes is not appointed by the Company within 90 days after the earlier of (x) the Company’s receipt of notice from DTC of such cessation and (y) the Company becoming aware of such cessation; or 

(iii) an Event of Default has occurred and is continuing and the Registrar has received a request from DTC for the
issuance of Definitive Notes in exchange for such Global Note or Global Notes; 
 the Notes Custodian shall surrender such Global Note or Global
Notes to the Trustee for cancellation and the Company shall execute, and the Trustee, upon receipt of an Officers’ Certificate and Company Order for the authentication and delivery of Notes, shall authenticate and deliver in exchange for such
Global Note or Global Notes, Definitive Notes in an aggregate principal amount equal to the aggregate principal amount of such Global Note or Global Notes. Such Definitive Notes shall be registered in such names as DTC (or any nominee thereof) shall
identify in writing as the Beneficial Owners of the Notes represented by such Global Note or Global Notes. 
 (e)
Notwithstanding the foregoing, in connection with any transfer of beneficial interests in a Global Note to the Beneficial Owners thereof pursuant to Section 3.09(d), the Registrar shall reflect on its books and records the date and a decrease
in the principal amount of such Global Note in an amount equal to the principal amount of the beneficial interests in such Global Note to be transferred. 
 Section 3.10. CUSIP and ISIN Numbers. The Company in issuing the Notes may use “CUSIP” and “ISIN” numbers (if then generally in use) and, if so, the Trustee shall use
“CUSIP” and “ISIN” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on
the Notes or as contained in any notice of redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such CUSIP or ISIN
numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP and ISIN numbers.

(a) The Company will not, in a single transaction or a series of transactions, consolidate or merge or combine with or into any
other Person, or sell, assign, convey, transfer, lease or dispose of all or substantially all of the assets of the Company and its Subsidiaries (taken as a whole), in a single transaction or a series of related transactions, to any other
Person, unless: 
 (i) either (A) the Company will be the surviving or continuing corporation, or (B) the Person formed
by or surviving such consolidation or merger (if not the Company) or to which such sale, assignments, lease, conveyance, transfer or other disposition shall be made (collectively, the “Successor”) is a corporation organized and
validly existing under the laws of the Cayman Islands, the United States of America or any state thereof, or any other similar jurisdiction so long as neither the laws of any such jurisdiction nor any such transaction would adversely affect the
Holders, and the Successor expressly assumes, by a supplemental indenture hereto in form and substance satisfactory to the Trustee, all of the Obligations of the Company under the Securities and this Indenture; and 

(ii) immediately after giving effect to such transaction and the assumption of the obligations as set forth in clause (a)(i) above, if
applicable, no Default shall have occurred and be continuing. 
 (iii) the Company delivers to the Trustee an Officers’
Certificate and an Opinion of Counsel (subject to customary exceptions and qualifications), each stating that such consolidation, merger, sale, assignment, conveyance, transfer, lease or other disposition and the supplemental indenture (if any)
comply with this Indenture and that all conditions precedent to such transaction have been satisfied. 
 (b) For purposes of the
foregoing, the sale, lease, transfer, conveyance or other disposition or assignment of all or substantially all of the assets of one or more of the Company’s Subsidiaries, the Equity Interests of which constitute all or substantially all of the
assets of the Company, will be deemed to be the transfer of all or substantially all of the assets of the Company. 
 (c) Upon
any consolidation, combination or merger of the Company, or any sale, lease, transfer, conveyance or other disposition or assignment of all or substantially all of the assets of the Company in accordance with the foregoing, in which the Company is
not the continuing obligor under the Securities and this Indenture, the Successor will succeed to, and be substituted for, and may exercise every right and power of, the Company under the Securities and this Indenture with the same effect as if such
Successor had been named therein as the Company, and, except in the case of such a lease, the Company will be released from its Obligations under the Securities and this Indenture.

 REPORTING OBLIGATIONS

Section 13 or 15(d) of the Exchange Act; and information, documents and reports filed by the Company with the SEC by electronic means or filing of documents pursuant to the SEC’s “EDGAR” system (or any successor electronic filing

 (b)
promptly and in any event within 10 days after the Company becomes aware of the occurrence of a Default, an Officers’ Certificate setting forth the details of the Default, and the action which the Company is taking or proposes to take with

 ARTICLE 6 
 REDEMPTION OF NOTES 

Section 6.01. Optional Redemption. 
 (a) Prior to September 1, 2015, the Notes will not be redeemable at the Company’s option. 
 (b) At any time on or after September 1, 2015 and before September 1, 2017, subject to the terms and conditions of this Article 6, the Company may, at its option, redeem the Notes for cash in
whole or in part if the VWAP of Ordinary Shares is greater than or equal to 125% of the applicable Conversion Price for at least 20 Trading Days during any 30 consecutive Trading Day period ending within five Trading Days prior to the Company’s
notice of redemption. On or after September 1, 2017, subject to the terms and conditions of this Article 6, the Company may, at its option, redeem the Notes for cash in whole or in part at any time or from time to time. In each case, the
redemption price (the “Redemption Price”) will be equal to 100% of the principal amount of the Notes to be redeemed, together with accrued and unpaid interest to but excluding the Redemption Date. However, if the Redemption Date
falls after a Regular Record Date and on or prior to the corresponding Interest Payment Date, the Company will pay the full amount of accrued and unpaid interest due on such Interest Payment Date to the Holder of record at 5:00 p.m., New York City
time, on the corresponding Regular Record Date, and not to the Holder submitting the Notes for redemption, if different. 

  
 13 

 Section 6.02. Election to Redeem; Notice to Trustee. In case of any redemption
at the election of the Company, the Company shall, on or prior to the date that is 15 days prior to the date on which notice is given to the Holders (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date and of the principal amount of Notes to be redeemed and shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Notes to be redeemed pursuant to Section 6.03. Any such notice may be
cancelled at any time prior to notice of such redemption being sent to any Holder and shall thereby be void and of no effect. 

Section 6.03. Selection by Trustee of Notes to Be Redeemed. If less than all the Notes are to be redeemed at any time
pursuant to this Article 6, the particular Notes to be redeemed (in principal amounts of $2,000 or an integral multiple of $1,000 in excess thereof) shall be selected by the Trustee, from the outstanding Notes not previously called for redemption,
by lot or on a pro rata basis among the Notes or by such other method as the Trustee shall consider fair and appropriate, including any method required by DTC or any successor depositary (and in such manner as is not prohibited by applicable
legal requirements) and which may provide for the selection for redemption of portions of the principal of the Notes; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Note not redeemed
to less than $1,000. If any Note is to be redeemed in part only, a new Note in principal amount equal to the unredeemed principal portion will be issued. 
 The Trustee shall notify the Company in writing, within seven calendar days from the Trustee’s receipt of a notice of redemption from the Company, of the Notes selected for redemption and, in the
case of any Notes selected for partial redemption, the principal amount thereof to be redeemed. 
 For all purposes of the
Indenture, unless the context otherwise requires, all provisions relating to redemption of Notes shall relate, in the case of any Note redeemed or to be redeemed only in part, to the portion of the principal amount of such Note which has been or is
to be redeemed. 
 If any Notes selected for partial redemption are thereafter surrendered for conversion in part before
termination of the conversion right with respect to the portion of the Notes so selected, the converted portion of such Notes shall be deemed (so far as may be), solely for purposes of determining the aggregate principal amount of Notes to be
redeemed by the Company, to be the portion selected for redemption. Notes which have been converted during a selection of Notes to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection. Nothing in this
Section 6.03 shall affect the right of any Holder to convert any Notes pursuant to Article 11 before the termination of the conversion right with respect thereto. 
 In the event of any redemption in part (pursuant to the provisions of this Article 6), the Company will not be required to issue, register the transfer of or exchange any Note during a period of 15 days
before the redemption notice is sent, or register the transfer of or exchange any Note so selected for redemption, in whole or in part, except the unredeemed portion of any Note being redeemed in part. 

  
 14 

 Section 6.04. Notice of Redemption. Notice of redemption shall be given in the
manner provided for in Section 10.02 of the Base Indenture not less than 20 nor more than 60 calendar days (each such time period being subject to the rules and procedures, if any, of DTC, if then applicable) prior to the Redemption Date, to
the Trustee, the Paying Agent, the Conversion Agent and each Holder of Notes to be redeemed. The Trustee shall give notice of redemption in the Company’s name and at the Company’s expense; provided, however, that the Company shall
deliver to the Trustee an Officers’ Certificate, at least 15 calendar days prior to the date on which notice is required to be given to the Holders (unless shorter notice shall be satisfactory to the Trustee), requesting that the Trustee give
such notice at the Company’s expense and setting forth the information to be stated in such notice as provided in the following items. 
 All notices of redemption shall state: 
 (a) the Redemption Date; 

(b) the Redemption Price; 
 (c) the then current Conversion Rate and provide a statement that the Notes called for redemption may be converted at any time before 5:00 p.m., New York City time, on the Business Day prior to the
Redemption Date, and that Holders who wish to convert Notes must comply with the relevant procedures; 
 (d) if less than all
outstanding Notes are to be redeemed, the identification of the particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding
after such partial redemption; 
 (e) in case any Note is to be redeemed in part only, the notice which relates to such Note
shall state that on and after the Redemption Date, upon surrender of such Note, the Holder will receive, without charge, a new Note or Notes of authorized denominations for the principal amount thereof remaining unredeemed; 

(f) that on the Redemption Date the Redemption Price will become due and payable upon each such Note, or the portion thereof, to be
redeemed, and, unless the Company defaults in making the redemption payment, that interest on Notes called for redemption (or the portion thereof) will cease to accrue on and after said date; 

(g) the place or places where such Notes are to be surrendered for payment of the Redemption Price; 

(h) the name and address of the Paying Agent and the Conversion Agent; 

(i) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price; and 

(j) the CUSIP or ISIN number, and that no representation is made as to the accuracy or correctness of the CUSIP or ISIN number, if any,
listed in such notice or printed on the Notes. 

  
 15 

 Section 6.05. Deposit of Redemption Price. Prior to 10:00 a.m., New York City
time, on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in 2.05 of the Base Indenture) an amount of money
sufficient to pay the Redemption Price of all the Notes which are to be redeemed on that date other than Notes or portions of Notes called for redemption that are beneficially owned by the Company and have been delivered by the Company to the
Trustee for cancellation. 
 Section 6.06. Notes Payable on Redemption Date. Notice of redemption having been given
as aforesaid, the Notes so to be redeemed shall, on the Redemption Date, unless converted, become due and payable at the Redemption Price, and from and after such date (unless the Company shall default in the payment of the Redemption Price or
accrued and unpaid interest), such Notes shall cease to bear interest. Upon surrender of any such Note for redemption in accordance with said notice, such Note shall be paid by the Company at the Redemption Price. 

If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate borne by the Notes. 
 Section 6.07 Notes Redeemed in Part.
Any Note which is to be redeemed only in part (pursuant to the provisions of this Article 6) shall be surrendered at the office or agency of the Company maintained for such purpose pursuant to 4.02 of the Base Indenture (with, if the Company or
the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Company
shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Note at the expense of the Company, a new Note or Notes, of any authorized denomination as requested by such Holder, in an aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of the Note so surrendered; provided that each such new Note will be in a principal amount of $2,000 and integral multiples of $1,000 in excess thereof.

consideration in accordance with Section 8.02 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the
Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no payment or delivery, as the case may be, had occurred pursuant to Section 8.01 until such time as the Trustee or such Paying Agent is
permitted to apply all such money in accordance with Section 8.02; provided that if the Company has made any payment of the principal amount of (including the relevant Termination of Trading Repurchase Price or Redemption Price) or

the money, Ordinary Shares or other consideration held by the Trustee or such Paying Agent.

 PURCHASE AT THE OPTION OF HOLDERS UPON A TERMINATION
OF TRADING; 
 PURCHASE AT THE OPTION
OF HOLDERS 
 Section 10.01. Purchase at the Option of the Holder Upon
a Termination of Trading. If a Termination of Trading occurs at any time prior to Stated Maturity, each Holder will have the right (“Termination of Trading Purchase Right”), at such Holder’s option, to require the Company
to purchase any or all of such Holder’s Notes, in integral multiples of $1,000, on a date specified by the Company that is no less than the 20th Business Day nor more than the 35th Business Day after the date of the Company Notice of the occurrence of such Termination of Trading (subject to
extension to comply with applicable law, as provided in Section 10.03(d)) (the “Termination of Trading Purchase Date”). The Company shall purchase such Notes at a price (the “Termination of Trading Purchase
Price”), which shall be paid in cash, equal to 100% of the principal amount of the Notes to be purchased plus accrued and unpaid interest to but excluding the Termination of Trading Purchase Date, unless the Termination of Trading Purchase
Date is between a Regular Record Date and the Interest Payment Date to which it relates, in which case the Termination of Trading Purchase Price shall equal 100% of the principal amount of Notes to be purchased and accrued and the Company will pay
the full amount of accrued and unpaid interest due on such Interest Payment Date to the Holder on the Regular Record Date corresponding to such Interest Payment Date, and the Termination of Trading Purchase Price will be payable to the Holder who
presents a Note for purchase. 
 (a) Notice of Termination of Trading. The Company, or at its request
(which must be received by the Paying Agent at least three Business Days (or such lesser period as agreed to by the Paying Agent) prior to the date the Paying Agent is requested to give such notice as described below) the Paying Agent, in the name
of and at the expense of the Company, shall provide or cause to be provided to all Holders, the Conversion Agent and the Trustee a Company Notice of the occurrence of a Termination of Trading and of the purchase right arising as a result thereof,
including the information required by Section 10.03(a) hereof, on or before the 5th calendar day after the occurrence of such Termination of Trading under clause (1) of such definition and on or before the 5th calendar day after the consummation of the transaction that is the subject of the public announcement described under
clause (2) of the definition of Termination of Trading, and in each case, promptly following any extension of the Termination of Trading Purchase Date to comply with applicable law. The Company shall promptly furnish to the Paying Agent a copy
of such Company Notice. 
 (b) Exercise of Option. For a Note to be so purchased at the option of the Holder, such Holder
must deliver to the Paying Agent such Note duly endorsed for transfer, together with a written notice of purchase (a “Termination of Trading Notice”) in the form entitled “Form of Termination of Trading Notice” attached to
the Note duly completed, at any time after the occurrence of the Termination of Trading and prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Termination of Trading Purchase Date, subject to extension to comply
with applicable law. The Termination of Trading Notice shall state: 
 (i) if certificated, the certificate
numbers of the Notes which the Holder shall deliver to be purchased, or if not certificated, such notice must comply with appropriate DTC procedures; 

  
 23 

 (ii) the portion of the principal amount of the Notes which the Holder shall
deliver to be purchased, which portion must be $1,000 in principal amount or an integral multiple thereof; and 

(iii) that such Notes shall be purchased as of the Termination of Trading Purchase Date pursuant to the terms and
conditions specified in paragraph 4 of the Notes and in this First Supplemental Indenture. 
 (c) Procedures. The Company
shall purchase from a Holder, pursuant to this Section 10.01, Notes if the principal amount of such Notes is $1,000 or an integral multiple of $1,000 if so requested by such Holder. 

Any purchase by the Company contemplated pursuant to the provisions of this Section 10.01 shall be consummated by the delivery of
the Termination of Trading Purchase Price to be received by the Holder promptly following the later of the Termination of Trading Purchase Date or the time of book-entry transfer or delivery of the Notes. 

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Termination of Trading Notice contemplated
by this Section 10.01 shall have the right at any time prior to 5:00 p.m., New York City time, on the Business Day immediately preceding to the Termination of Trading Purchase Date to withdraw such Termination of Trading Notice (in whole or in
part) by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 10.03(b). 
 The Paying
Agent shall promptly notify the Company of the receipt by it of any Termination of Trading Notice or written notice of withdrawal thereof. 
 At or before 11:00 a.m. (New York City time) on the Termination of Trading Purchase Date, the Company shall deposit with the Paying Agent (or if the Company or an Affiliate of the Company is acting as the
Paying Agent, shall segregate and hold in trust) cash sufficient to pay the aggregate Termination of Trading Purchase Price of the Notes to be purchased pursuant to this Section 10.01. Payment by the Paying Agent of the Termination of Trading
Purchase Price for such Notes shall be made promptly following the later of the Termination of Trading Purchase Date or the time of book-entry transfer or delivery of such Notes. If the Paying Agent holds, in accordance with the terms of this First
Supplemental Indenture, cash sufficient to pay the Termination of Trading Purchase Price of such Notes on the Termination of Trading Purchase Date, then, on and after such date, such Notes shall cease to be outstanding and interest on such Notes
shall cease to accrue, whether or not book-entry transfer of such Notes is made or such Notes are delivered to the Paying Agent, and all other rights of the Holder shall terminate (other than the right to receive the Termination of Trading Purchase
Price and previously accrued and unpaid interest, upon delivery or transfer of the Notes). 
 The Company shall require each
Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all cash held by the Paying Agent for the payment of the Termination of Trading Purchase Price and shall
notify the Trustee of any default by the Company in making any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall segregate the cash held by it as Paying Agent and hold it as a separate trust fund. The Company
at any time may require a Paying Agent to deliver all cash held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon doing so, the Paying Agent shall have no further liability for the cash delivered to the Trustee.

  
 24 

 Notwithstanding the foregoing, there shall be no purchase of any Notes pursuant to
Section 10.01 if an Event of Default has occurred and is continuing (other than an Event of Default that is cured by the payment of the Termination of Trading Purchase Price). 

Section 10.02. Purchase of Notes at the Option of the Holder. 

(a) A Holder shall have the option to require the Company to purchase any outstanding Notes on each of September 1, 2015 and
September 1, 2017 (each, a “Purchase Date”), at a price (the “Purchase Price”) which shall be paid in cash, equal to 100% of the principal amount of the Notes to be repurchased plus any accrued and unpaid
interest to but excluding the Purchase Date. If the Purchase Date is between a Regular Record Date and the Interest Payment Date to which it relates, the Company will pay the full amount of accrued and unpaid interest due on such Interest Payment
Date to the Holder on the Regular Record Date corresponding to such Interest Payment Date, and the Purchase Price will be payable to the Holder who presents a Note for purchase. A Holder shall have the option describe in this clause (a) upon:

 (i) delivery to the Paying Agent and the Company by the Holder of a written notice of purchase (a
“Purchase Notice”), in the form entitled “Form of Purchase Notice” attached to the Note duly completed, at any time from 9:00 a.m., New York City time, on the date that is 20 Business Days prior to the relevant Purchase

$1,000 in principal amount or a multiple thereof; 
 (C) that such Notes shall be purchased by the Company as of
the Purchase Date pursuant to the terms and conditions specified in paragraph 4 of the Notes and in this First Supplemental Indenture; and 
 (ii) delivery or book-entry transfer of such Notes to the Paying Agent (together with all necessary endorsements) at the offices of the Paying Agent, such delivery or transfer being a condition to receipt
by the Holder of the Purchase Price therefor; provided, however, that such Purchase Price shall be so paid pursuant to this Section 10.02 only if the Notes so delivered or transferred to the Paying Agent shall conform in all respects to
the description thereof in the related Purchase Notice. 
 (b) The Company shall purchase from a Holder, pursuant to this
Section 10.02, Notes if the principal amount of such Notes is $1,000 or a multiple of $1,000 if so requested by such Holder. 

  
 25 

 (c) Any purchase by the Company contemplated pursuant to the provisions of this
Section 10.02 shall be consummated by the delivery of the Purchase Price to be received by the Holder promptly following the later of the Purchase Date or the time of book-entry transfer or delivery of the Notes. 

(d) Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Purchase Notice contemplated by this
Section 10.02 shall have the right at any time prior to 5:00 p.m., New York City time, on the Business Day prior to the Purchase Date to withdraw such Purchase Notice (in whole or in part) by delivery of a written notice of withdrawal to the
Paying Agent in accordance with Section 10.03(b). 
 (e) The Paying Agent shall promptly notify the Company of the receipt
by it of any Purchase Notice or written notice of withdrawal thereof. 
 (f) At or before 11:00 a.m. (New York City time) on the
Purchase Date, the Company shall deposit with the Paying Agent (or if the Company or an Affiliate of the Company is acting as the Paying Agent, shall segregate and hold in trust) cash sufficient to pay the aggregate Purchase Price of the Notes to be
purchased pursuant to this Section 10.02. Payment by the Paying Agent of the Purchase Price for such Notes shall be made promptly following the later of the Purchase Date or the time of book-entry transfer or delivery of such Notes. If the
Paying Agent holds, in accordance with the terms of this First Supplemental Indenture, cash sufficient to pay the Purchase Price of such Notes on the Purchase Date, then, on and after such date, such Notes shall cease to be outstanding and interest
on such Notes shall cease to accrue, whether or not book-entry transfer of such Notes is made or such Notes are delivered to the Paying Agent, and all other rights of the Holder shall terminate (other than the right to receive the Purchase Price and
previously accrued interest upon delivery or transfer of the Notes). 
 (g) The Company shall require each Paying Agent (other
than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all cash held by the Paying Agent for the payment of the Purchase Price and shall notify the Trustee of any default by the
Company in making any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall segregate the cash held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent
to deliver all cash held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon doing so, the Paying Agent shall have no further liability for the cash delivered to the Trustee. 

Section 10.03. Further Conditions and Procedures for Purchase at the Option of the Holder Upon a Termination of Trading and
Purchase of Notes at the Option of the Holder. 
 (a) Notice of Purchase Date or Termination of
Trading. The Company shall send notices (each, a “Company Notice”) to the Holders, the Trustee, the Conversion Agent and the Paying Agent, (i) on or before the 5th calendar day after the occurrence of such Termination of Trading under clause (1) of such definition and on or

 ARTICLE 11 
 CONVERSION 

Section 11.01. Conversion of Notes.  
 (a) Right to Convert. Subject to the procedures for conversion set forth in this Article 11, and subject to prior maturity, redemption or repurchase, a Holder may convert its Notes prior

  
 29 

 
to 5:00 p.m., New York City time, on the Business Day immediately preceding Stated Maturity. A Holder may convert a portion of the principal amount of Notes if the portion is $2,000 or an
integral multiple of $1,000 in excess thereof. The number of Ordinary Shares issuable or the combination of cash payable and the number of Ordinary Shares issuable, if any, upon conversion of a Note shall be determined as set forth in
Section 11.01(c). 
 (b) Conversion Procedures. The following procedures shall apply to the conversion of Notes
under this Section 11.01: 
 (i) In respect of a Definitive Note, a Holder must (A) complete and
manually sign the conversion notice on the back of the Note, or a facsimile of such conversion notice; (B) deliver such conversion notice, which is irrevocable, and the Note to the Conversion Agent, with a copy to the Company; (C) to the
extent any Ordinary Shares issuable upon conversion are to be issued in a name other than the Holder’s, furnish appropriate endorsements and transfer documents as may be required by the Conversion Agent; (D) if required pursuant to
Section 11.01(e) below, pay all transfer or similar taxes; and (E) if required pursuant to Section 3.05, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled. 

(ii) In respect of a beneficial interest in a Global Note, a Beneficial Owner must comply with DTC’s procedures for
converting a beneficial interest in a Global Note and, if required pursuant to Section 3.05, pay funds equal to interest payable on the next Interest Payment Date to which such Beneficial Owner is not entitled, and if required, taxes or duties,
if any. 
 The date a Holder satisfies the foregoing requirements is the “Conversion Date” hereunder with respect to a
conversion under Section 11.01. If the Company elects to mandatorily convert the Notes pursuant to Section 11.09, the Notes converted pursuant to such election will be converted automatically, with no further action by the Holders thereof,
on the conversion date specified in the notice of conversion, which will be deemed the “Conversion Date” for such mandatory conversion under this Indenture. With respect to a conversion of a Note pursuant hereto, if the Company elects to
satisfy the applicable Conversion Obligation solely in Ordinary Shares (plus cash in lieu of fractional shares), the Person in whose name any Ordinary Shares shall be issuable upon such conversion and upon delivery of Ordinary Shares pursuant to
Section 11.03 shall be treated as a stockholder of record of the Company, to the extent permitted by law, of such Ordinary Shares as of 5:00 p.m., New York City time, on the relevant Conversion Date. If the Company elects to satisfy the
applicable Conversion Obligation in cash and Ordinary Shares (plus cash in lieu of fractional shares), the Person in whose name any Ordinary Shares shall be issuable upon such conversion will become the holder of record of such Ordinary Shares as of
5:00 p.m., New York City time, on the last Trading Day (the “Relevant Date”) of the related ten Trading Day period used to determine the Applicable Stock Price for such conversion. On and after the Conversion Date with respect to a
conversion of a Note pursuant hereto, all rights of the Holder of such Note shall terminate, other than the right to receive the consideration deliverable upon conversion of such Note as provided herein. A Holder of a Note is not entitled, as such,
to any rights of a holder of Ordinary Shares until, if such Holder converts such Note and is entitled pursuant hereto to receive Ordinary Shares in respect of such conversion, 5:00 p.m., New York City time, on the Conversion Date or the Relevant
Date or respective Conversion Dates or Relevant Dates, as the case may be, with respect to such conversion. 

  
 30 

 If a Holder converts more than one Note at the same time, the number of Ordinary Shares
issuable or the combination of the cash payable and number of Ordinary Shares issuable upon the conversion, if any, shall be based on the total principal amount of the Notes converted. 

Upon surrender of a Note that is converted in part, the Company shall execute, and the Trustee or the Authenticating Agent shall
authenticate and deliver to the Holder, a new Note in an authorized denomination equal in principal amount to the unconverted portion of the Note surrendered. 
 Delivery of Ordinary Shares will be accomplished by delivery to the Conversion Agent of certificates for the relevant number of Ordinary Shares, other than in the case of Holders of Global Notes in
book-entry form with DTC, in which case Ordinary Shares shall be delivered in accordance with DTC customary practices. 
 (c)
Settlement Upon Conversion. In the event that the Company receives a Holder’s notice of conversion pursuant to this Section 11.01, the Company will notify the relevant Holders within two Business Days following the Conversion Date
whether the Company will satisfy its obligation to convert the Notes through delivery of (x) Ordinary Shares pursuant to clause (ii) below (plus cash in lieu of fractional shares) or (y) a combination of cash and Ordinary Shares
pursuant to clause (i) below. Notwithstanding the foregoing, (a) if the Company elects to redeem the Notes under Section 6.01, the Company will, in the notice of redemption, specify whether the Company will settle the conversion
obligations with respect to Notes called for redemption pursuant to clause (i) or (ii) below, which election shall apply to all Notes converted following such notice of redemption, and (b) if the Company elects to effect a mandatory
conversion of the Notes pursuant to Section 11.09, the Company will specify in the notice of such mandatory conversion whether it will settle such mandatory conversion pursuant to clause (i) or (ii) below. If the Company does not make
a settlement election, the Company shall be deemed to have elected to settle conversion obligations of Notes pursuant to clause (ii) below. The Company will treat all converting Holders with the same Conversion Date using the same settlement
method, but may settle conversions occurring on different Conversion Dates using different settlement methods. 

(i) If the Company chooses or has to satisfy its obligation to convert the Notes (the “Conversion
Obligation”) by a combination of cash and Ordinary Shares, upon conversion the Company will, deliver to converting Holders, in respect of each $1,000 principal amount of Notes being converted, a “Settlement Amount” equal to
(i) cash in an amount equal to the lesser of (a) the Conversion Value and (b) $1,000; (ii) if the Conversion Value is greater than $1,000, a number of Ordinary Shares equal to the difference between the Conversion Value and
$1,000, divided by the Applicable Stock Price for such Notes; and (iii) cash in lieu of any fractional shares as described below in Section 11.01(d). 
 The Settlement Amount in respect of any Note converted pursuant to this clause (i) will be delivered to converting Holders as soon as practicable following the last day following the determination of
the Applicable Stock Price for such Note. 
 (ii) If the Company elects to satisfy all of its Conversion
Obligation with respect to Notes to be converted in Ordinary Shares, the Company will deliver to any converting Holder, for each $1,000 principal amount of the Notes, a number of Ordinary Shares equal to the Conversion Rate for such Notes, plus cash
in lieu of any fractional shares determined as described below in Section 11.01(d). 

  
 31 

 The Ordinary Shares in respect of any Note converted (and cash in lieu of
any fractional shares) pursuant to this clause (ii) will be delivered through the Conversion Agent or DTC within three Business Days following the Conversion Date for such Note. 

(d) Cash Payments in Lieu of Fractional Shares. The Company shall not issue a fractional share of Ordinary Shares upon conversion
of Notes. Instead the Company shall deliver cash for the current market value of the fractional share. The current market value of a fractional share shall be determined to the nearest 1/10,000th of a share by multiplying the Last Reported Sale
Price on the Conversion Date by the fractional amount and rounding the product to the nearest whole cent. 
 (e) Taxes on
Conversion. If a Holder converts Notes, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issuance and delivery of Ordinary Shares upon the conversion. However, the Holder shall pay any such tax which is
due because the Holder requests the shares to be issued in a name other than the Holder’s name. The Conversion Agent may refuse to deliver the certificates representing the Ordinary Shares being issued in a name other than the Holder’s
name until the Conversion Agent receives a sum sufficient to pay any tax which shall be due because the shares are to be issued in a name other than the Holder’s name, but the Conversion Agent shall have no duty to determine if any such tax is
due. Nothing herein shall preclude any withholding of tax required by law. 
 (f) Certain Covenants of the Company.

 (i) The Company shall, prior to issuance of any Notes hereunder, and from time to time as may be necessary,
reserve out of its authorized but unissued Ordinary Shares or Ordinary Shares held in treasury, a sufficient number of Ordinary Shares, free of preemptive rights, to permit the conversion of the Notes. 

(ii) All Ordinary Shares delivered upon conversion of the Notes shall be newly issued shares or treasury shares, shall be
duly and validly issued and fully paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim. 
 (iii) The Company shall endeavor promptly to comply with all federal and state securities laws regulating the issuance and delivery of Ordinary Shares upon the conversion of Notes, if any, and shall cause
to have listed or quoted all such Ordinary Shares on each U.S. national securities exchange or over-the-counter or other domestic market on which the Ordinary Shares is then listed or quoted. 

(iv) Before taking any action which would cause an adjustment increasing the Conversion Rate to an amount that would cause
the Conversion Price to be reduced below the then par value per share of the Ordinary Shares, if any, of the Ordinary Shares issuable upon conversion of the Notes, the Company should take all corporate action which may, in the opinion of its
counsel, be necessary in order that the Company may validly and legally issue shares of such Ordinary Shares at such adjusted Conversion Rate. 

  
 32 

 Section 11.02. Adjustments to Conversion Rate. The Conversion Rate shall be
adjusted by the Company as follows: 
 (a) If the Company issues Ordinary Shares to all or substantially all holders of Ordinary
Shares as a dividend or distribution, the Conversion Rate will be adjusted based on the following formula: 
  
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution;
			
	CR'	  	=	  	the Conversion Rate in effect on the Ex-Dividend Date for such dividend or distribution;
			
	OS0	  	=	  	the number of Ordinary Shares outstanding at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution;
and
			
	OS'	  	=	  	the number of Ordinary Shares that would be outstanding immediately after, and solely as a result of, such dividend or distribution.

 Such adjustment shall become effective immediately prior to 9:00 a.m., New York City time, on the Ex-Dividend Date for
such dividend or distribution. If any dividend or distribution of the type described in this Section 11.02(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted, effective as of the date the Company publicly
announces not to make such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (b) If the Company effects a subdivision or combination of Ordinary Shares, the Conversion Rate will be adjusted based on the following formula: 

 
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding the effective date of such subdivision or combination;

  
 33 

					
	CR'	  	=	  	the Conversion Rate in effect on the effective date of such subdivision or combination;
			
	OS0	  	=	  	the number of Ordinary Shares outstanding at 5:00 p.m., New York City time, on the Trading Day immediately preceding the effective date of such subdivision or combination;
and
			
	OS'	  	=	  	the number of Ordinary Shares that would be outstanding immediately after, and solely as a result of, such subdivision or combination.

 Such adjustment shall become effective immediately prior to 9:00 a.m., New York City time, on the date on which such
split or combination becomes effective. 
 (c) If the Company issues to all or substantially all the holders of Ordinary Shares
any rights or warrants (other than pursuant to any rights plan described in Section 11.02(d)(iii) below) entitling them to purchase, for a period of not more than 45 calendar days after the date of the announcement for such issuance, Ordinary
Shares at an aggregate price per share less than the average of the Last Reported Sale Prices of the Ordinary Shares during the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date such issuance was first
publicly announced, then the Conversion Rate will be adjusted based on the following formula: 
  
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Ex-Dividend Date for such issuance;
			
	CR'	  	=	  	the Conversion Rate in effect on the Ex-Dividend Date for such issuance;
			
	OS0	  	=	  	the number of Ordinary Shares outstanding at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Ex-Dividend Date for such issuance;
			
	Y	  	=	  	the total number of Ordinary Shares issuable pursuant to such rights or warrants; and
			
	Z	  	=	  	the number of Ordinary Shares equal to the quotient of (x) the aggregate price payable to exercise such rights or warrants divided by (y) the average of the Last Reported Sale
Prices of Ordinary Shares during the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date such issuance was first publicly announced.

  
 34 

 For purposes of this Section 11.02(c), in determining whether any rights or warrants entitle the
Holders to subscribe for or purchase Ordinary Shares at less than the average of the applicable Last Reported Sale Prices, and in determining the aggregate exercise or conversion price payable for such Ordinary Shares, there shall be taken into
account any consideration received by the Company for such rights or warrants and any amount payable on exercise or conversion thereof, with the value of such consideration, if other than cash, to be determined by the Board of Directors of the
Company. If any rights or warrants of the type described in this Section 11.02(a) are not so issued, the Conversion Rate shall again be readjusted, effective as of the date the Company publicly announces not to issue such rights or warrants, to
the Conversion Rate that would then be in effect if such issuance had not been declared. If any right or warrant described in this Section 11.02(c) is not exercised or converted prior to the expiration of the exercisability or convertibility
thereof, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such right or warrant had not been so issued. Any adjustment made pursuant to this Section 11.02(c) shall become effective immediately prior
to 9:00 a.m., New York City time, on the Ex-Dividend Date for the applicable distribution. 
 (d) If the Company distributes
shares of Capital Stock, evidences of its indebtedness or other assets, including securities, of the Company to all or substantially all the holders of the Ordinary Shares, excluding: 

(i) any dividends or distributions referred to in Section 11.02(a) above; 

(ii) shares delivered in connection with subdivisions of Ordinary Shares referred to in Section 11.02(b) above;

 (iii) rights and warrants referred to in Section 11.02(c) above; 

(iv) Spin-Offs to which the provisions set forth below in this Section 11.02(d) shall apply; 

(v) the rights or warrants referred to in this Section 11.02(d) below (to the extent and as specified therein); and

 (vi) dividends or distributions referred to in Section 11.02(e) below. 

then the Conversion Rate will be adjusted based on the following formula: 

 
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Ex-Dividend Date for such distribution;
			
	CR'	  	=	  	the Conversion Rate in effect on the Ex-Dividend Date for such distribution;

  
 35 

					
	SP0	  	=	  	the average of the Last Reported Sale Prices of Ordinary Shares over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
Ex-Dividend Date for such distribution; and
			
	FMV	  	=	  	the Fair Market Value (as determined by the Board of Directors of the Company) on the Ex-Dividend Date for such distribution of the shares of Capital Stock, evidences of
indebtedness, or assets, including securities, so distributed, expressed as an amount per Ordinary Share.

 Such adjustment shall become effective immediately prior to 9:00 a.m., New York City time, on the Ex-Dividend Date for
the applicable distribution. 
 If “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), other than in respect to a Public Spin-Off, in
lieu of the adjustment described in this Section 11.02(d), each Holder of Notes shall be entitled to receive upon conversion, in addition to Ordinary Shares, and, if applicable, cash payable on conversion, the kind and amount of assets
(including cash), shares of Capital Stock, evidences of indebtedness, securities or rights, warrants or options to purchase the Company’s securities, as applicable, that such Holder would have received if such Holder had converted such Notes
immediately prior to the record date for determining the shareholders entitled to receive such distribution. 
 With respect to an adjustment
pursuant to this Section 11.02(d) where there has been a payment of a dividend or other distribution on the Ordinary Shares consists of shares of Capital Stock of any class or series, or similar Equity Interest, in a Subsidiary or other
business unit (a “Spin-Off”), that are, or, when issued, will be, traded or listed on the Nasdaq Stock Market, the New York Stock Exchange or any other U.S. national securities exchange or market (a “Public
Spin-Off”), then the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on the Ex-Dividend Date of the distribution will be increased based on the following formula: 

 
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Ex-Dividend Date for such distribution;
			
	CR'	  	=	  	the Conversion Rate in effect on the Ex-Dividend Date for such distribution;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar Equity Interests distributed to holders of Ordinary Shares applicable to one share of Ordinary Shares
during the 10 consecutive Trading Day period commencing on, and including, the effective date of the Spin-Off; and
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of Ordinary Shares during the 10 consecutive Trading Day period commencing on, and including, the effective date of the
Spin-Off.

  
 36 

 Such adjustment shall occur immediately after the tenth Trading Day immediately following, and including,
the effective date of the Spin-Off. 
 If any such dividend or distribution described in this Section 11.02(d) is declared but not paid or
made, the Conversion Rate shall be readjusted, effective as of the date the Company publicly announces not to make such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been
declared. 
 Notwithstanding the delivery requirements set forth under Section 11.01(c), if an adjustment to the Conversion Rate is
required pursuant to this Section 11.02(d) during any settlement period in respect of Notes that have been tendered for conversion, delivery of the related conversion consideration will be delayed to the extent necessary in order to complete
the calculations provided for in this Section 11.02(d). 
 For purposes of Conversion Rate adjustments pursuant to this
Section 11.02(d), rights or warrants distributed by the Company to all or substantially all holders of Ordinary Shares entitling the holders thereof to subscribe for or purchase shares of Capital Stock (either initially or under certain
circumstances), which rights or warrants, until the occurrence of a specified event or events (a “Trigger Event”): (i) are deemed to be transferred with such Ordinary Shares; (ii) are not exercisable; and (iii) are
also issued in respect of future issuances of Ordinary Shares, shall be deemed not to have been distributed for purposes of Conversion Rate adjustments pursuant to this Section 11.02(d) and no adjustment to the Conversion Rate will be required
until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 11.02(d),
except as set forth under Section 11.06. If any such rights or warrants are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase or exchangeable for additional or different securities, evidences
of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Trigger Event with respect to new rights or warrants with such rights (and a termination or expiration of
the existing rights or warrants to the extent not exercised by any of the holders thereof), except as set forth in Section 11.06. In addition, except as set forth in Section 11.06, in the event of any distribution (or deemed distribution)
of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under
this Section 11.02(d) or Section 11.06 was made, (a) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon
such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Ordinary
Shares with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Ordinary Shares as of the date of such redemption or repurchase, and (b) in the case of such rights or warrant
that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued. 

  
 37 

 (e) If any dividends or other distributions by the Company consisting exclusively of cash to
all or substantially all holders of Ordinary Shares (other than dividends or distributions made in connection with liquidation, dissolution or winding-up of the Company), the Conversion Rate will be adjusted based on the following formula:

  
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution;
			
	CR'	  	=	  	the Conversion Rate in effect on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the average of the Last Reported Sale Prices of the Ordinary Shares during the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
Ex-Dividend Date for such dividend or distribution; and
			
	C	  	=	  	the amount in cash per share of Ordinary Shares that the Company pays as a dividend or otherwise distributes to holders of Ordinary Shares.

 An adjustment to the Conversion Rate made pursuant to this Section 11.02(e) shall become effective immediately prior
to 9:00 a.m., New York City time, on the Ex-Dividend Date for the applicable dividend or distribution. 
 If “C”
(as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the adjustment
described in this Section 11.02(e), each Holder of Notes shall be entitled to receive upon conversion, in addition to Ordinary Shares, and, if applicable, cash payable on conversion, the amount of cash that such Holder would have received if
such Holder had converted such Notes immediately prior to the record date for determining the shareholders entitled to receive such dividend or distribution. 
 If any such dividend or distribution described in this Section 11.02(d) is declared but not paid or made, the Conversion Rate shall be readjusted, effective as of the date the Company publicly
announces not to make such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (f) If the Company or any of its Subsidiaries purchases Ordinary Shares pursuant to a tender offer or exchange offer made by the Company or any of its Subsidiaries for all or any portion of the Ordinary
Shares, to the extent that the Fair Market Value (as determined below) of the cash and any other consideration included in the payment per Ordinary Share, exceeds the Last reported Sale Price of Ordinary Shares on the Trading Day immediately after
the last date on which tenders or exchanges may be made pursuant to such tender offer or exchange offer (the “Expiration Date”), as it may be amended, the Conversion Rate will be adjusted based on the following formula: 

  
 38 

  
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Expiration Date;
			
	CR'	  	=	  	the Conversion Rate in effect on the Trading Day immediately following the Expiration Date;
			
	AC	  	=	  	the Fair Market Value (as determined by the Board of Directors of the Company) on the Expiration Date, of the aggregate value of all cash and other consideration paid or payable for
the Ordinary Shares validly tendered or exchanged and not withdrawn as of the Expiration Date;
			
	OS0	  	=	  	the number of Ordinary Shares outstanding immediately before the last time tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration
Time”) (prior to giving effect to such tender or exchange offer);
			
	OS'	  	=	  	the number of Ordinary Shares outstanding immediately after the Expiration Time (after giving effect solely to such tender or exchange offer); and
			
	SP'	  	=	  	the average of the Last Reported Sale Prices of Ordinary Shares during the 10 consecutive Trading Day period commencing on, and including, the Trading Day immediately after the
Expiration Date.

 The adjustment to the Conversion Rate under this Section 11.02(f) shall become effective immediately prior to 9:00
a.m., New York City time, on the tenth Trading Day from, and including, the Trading Day immediately after the Expiration Date. If the Company or one of its Subsidiaries is obligated to purchase Ordinary Shares pursuant to any such tender or exchange
offer but is prevented by applicable law from effecting any such purchase, or all such purchases are rescinded, the Conversion Rate shall be readjusted to be the Conversion Rate that would be in effect if such tender or exchange offer had not been
made. Except as set forth in the previous sentence, if the application of the foregoing formula in this clause (f) would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made. 

Notwithstanding the delivery requirements set forth under Section 11.01(c), if an adjustment to the Conversion Rate is required pursuant to this
Section 11.02(f) during any settlement period in respect of Notes that have been tendered for conversion, delivery of the related conversion consideration will be delayed to the extent necessary in order to complete the calculations provided
for in this Section 11.02(f). 

  
 39 

 (g) Notwithstanding the foregoing provisions of this Section 11.02, no adjustment will
be made thereunder, nor shall an adjustment be made to the ability of a Holder to convert, for any distribution described therein if the Holder will otherwise participate in the distribution without conversion of such Holder’s Notes as if such
Holder held a number of Ordinary Shares equal to (i) (A) the principal amount of Notes held by such Holder, divided by (B) 1,000, multiplied by (ii) the Conversion Rate in effect immediately prior to the Ex-Dividend Date,
expiration date or other effective date of the applicable transaction, without having to convert their Notes. 
 (h) No
adjustment to the Conversion Rate will be made unless as specifically set forth in this Section 11.02 or Section 11.06. 
 (i) Without limiting the foregoing, no adjustment to the Conversion Rate need be made: 
 (i) except as specifically provided herein, for the issuance of Ordinary Shares or any securities convertible into or exchangeable for Ordinary Shares or carrying the right to purchase Ordinary Shares or
any such security; 
 (ii) for rights to purchase Ordinary Shares pursuant to a Company plan for reinvestment of
dividends or interest; or 
 (iii) for a change in the par value or no par value of Ordinary Shares. 

To the extent the Notes become convertible pursuant to this Article 11 into cash, no adjustment need be made thereafter as to the
cash. Interest will not accrue on the cash into which Notes are convertible. 
 If the Company publicly announces its intention
to enter into a transaction that would involve a sale, lease, transfer, conveyance or other disposition of all or substantially all of its property or assets to another Person which the Company reasonably believes will result in (i) a
Termination of Trading, (ii) another Person’s assumption of the Company’s obligations under the Indenture and the Notes, and (iii) a dividend or other distribution of consideration received in such transaction to holders of
Ordinary Shares, Holders of Notes will not have any rights to receive cash, Capital Stock, evidences of indebtedness, securities or rights, warrants or options to purchase securities, or any other property or assets (or any combination thereof) that
are distributed to holders of Ordinary Shares in connection with any such transaction and no adjustment to the Conversion Rate will be made unless such Holder of Notes shall have given its notice of conversion prior to 5:00 p.m., New York City time,
on the record date for any such distribution; provided that the Company shall have given notice to Holders of the Notes of and publicly announced by press release, in each case not less than 20 days prior to such record date, such record date and
specifying that Holders must convert prior to 5:00 p.m., New York City time, on such record date in order to participate in such distribution. 
 (j) All required calculations will be made to the nearest cent or 1/10,000th of a share, as the case may be. If a Conversion Rate adjustment becomes effective on any Ex-Dividend Date in accordance with
Section 11.02, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related record date would be treated as the record holder of Ordinary Shares as of the related Conversion Date as provided in
Section 11.01(b) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion 

  
 40 

 
Rate adjustment provisions in Section 11.02, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be
treated as if such Holder were the record owner of Ordinary Shares on an unadjusted basis on such Conversion Date and participate in the related dividend, distribution or other event giving rise to such adjustment. 

(k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly deliver to the Trustee and any Conversion
Agent, other than the Trustee, an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Trust Officer of the Trustee shall
have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has knowledge is still in effect. 

(l) For purposes of this Section 11.02, the number of Ordinary Shares at any time outstanding shall not include shares held in the
treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of Ordinary Shares. The Company shall not pay any dividend or makes any distribution on, or issues any rights, options or warrants
in respect of, Ordinary Shares held in treasury by the Company. 
 (m) Whenever any provision of this Article 11 requires the
Company to calculate an average of Last Reported Sale Prices over multiple days, the Company will make appropriate adjustments to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the
Conversion Rate that occurs, at any time during the period during which the average is to be calculated. In addition, if during a period applicable for calculating the VWAP or Last Reported Sale Price of Ordinary Shares an event occurs that requires
an adjustment to the Conversion Rate, the VWAP or Last Reported Sale Price of Ordinary Shares shall be calculated for such period in a manner determined in good faith by the Company to appropriately reflect the impact of such event on the price of
the Ordinary Shares during such period. 
 (n) The applicable Conversion Rate shall be adjusted only once for a single event or
occurrence that would require an adjustment under more than one of the adjustment events in this Section 11.02. 
 (o) The
Company may make such increases in the Conversion Rate, in addition to those required by Section 11.02(a), (b), (c), (d), (e) and (f), as the Board of Directors of the Company considers to be advisable to avoid or diminish any income tax
to holders of Ordinary Stock or rights to purchase Ordinary resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. 

(p) To the extent permitted by applicable law and subject to the applicable rules of the New York Stock Exchange or the applicable rules
of any stock exchange on which the Ordinary Shares are listed at the relevant time, the Company from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least twenty (20) Business Days, the
increase is irrevocable during the period and the Board of Directors of the Company shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion
Rate is increased 

  
 41 

 
pursuant to the preceding sentence, the Company shall send to Holders of the Notes a notice of the increase at least fifteen (15) calendar days prior to the date the increased Conversion
Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 

Section 11.03. Make Whole Payment in Connection with a Voluntary Conversion. In addition to the consideration due upon
conversion under Section 11.01, each Holder who elects to convert any of its Notes at the Holder’s option prior to September 1, 2017 will receive a number of additional Ordinary Shares (the “Voluntary Conversion Make Whole
Payment”) for the Notes being converted. The Voluntary Conversion Make Whole Payment will be a number of Ordinary Shares equal to the aggregate amount of interest payments that would have been payable on such converted Notes from the last
day through which interest was paid on the Notes (or from the date of original issuance if no interest has been paid), through and including September 1, 2017, up to a maximum of $157.50 per $1,000 principal amount of notes divided by the
greater of (i) the VWAP of the Ordinary Shares on the Conversion Date, and (ii) $1.00 (subject to inversely proportionate adjustment in the event of any adjustment to the Conversion Rate pursuant to Section 11.02). Delivery of any
Ordinary Shares in satisfaction of any Voluntary Conversion Make Whole Payment will be made within three Business Days of the Conversion Date, in the same manner as Ordinary Shares delivered in settlement of the conversion obligation (including with
respect to cash in lieu of fractional shares) described in Section 11.01. 
 Section 11.04. Effect of
Recapitalizations, Reclassifications, and Changes of Ordinary Shares.  
 (a) If the Company (i) reclassifies or
changes the Ordinary Shares (other than changes in par value or changes resulting from a subdivision or combination to which Section 11.02(b) applies), or (ii) consolidates or merges with or into any Person or sells, leases, transfers,
conveys or otherwise disposes of all or substantially all of the property or assets of the Company and its Subsidiaries to another Person, (any such event or transaction described under (i) or (ii), a “Reorganization Event”),
and, in either case holders of Ordinary Shares receive stock, other securities or other property or assets (including cash or any combination thereof), with respect to or in exchange for their Ordinary Shares, then from and after the effective date
of such Reorganization Event, each outstanding Note will, without the consent of any Holders of the Notes become convertible into, in lieu of Ordinary Shares otherwise deliverable, the same type (in the same proportions) of consideration received by
holders of Ordinary Shares in such Reorganization Event (the “Reference Property”) that a Holder would have been entitled to receive upon such Reorganization Event in respect of Ordinary Shares, as provided below. If the
Reorganization Event causes Ordinary Shares to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of shareholder election), the Reference Property will be deemed to be the kind and
amount of consideration elected to be received by a majority of Ordinary Shares voting for such election (if electing between two types of consideration) or a plurality of Ordinary Shares voting for such an election (if electing between more than
two types of consideration), as the case may be. Upon such Reorganization Event, the Company or any Successor Company will enter into a supplemental indenture consistent with the foregoing. Such supplemental indenture shall provide for provisions
and adjustments which shall be as nearly equivalent as may be practicable to the provisions and adjustments provided for in this Article 11 and the definition of Termination of Trading, as 

  
 42 

 
appropriate, as determined in good faith by the Company (which determination shall be conclusive and binding), to make such provisions apply to such other Person if different from the original
issuer of the Notes. Notwithstanding anything herein to the contrary, pursuant to Section 11.02(i), the Notes will not become convertible into, in lieu of Ordinary Shares otherwise deliverable, the Reference Property as described in this
Section 11.04 unless such Holder has exercised its conversion right as described in Section 11.02(i). 
 (b) At and
after the effective time of any such Reorganization Event, settlement of Notes converted, including any Ordinary Shares that would be delivered pursuant to Section 11.03 and Section 11.09, shall be in units of Reference Property or cash
and units of Reference Property, if applicable, determined in accordance with Section 11.01(c)(i) and Section 11.01(c)(ii) above. The Conversion Rate will relate to units of Reference Property (a “unit” of Reference
Property being the kind and amount of reference property that a holder of one share of Ordinary Shares would have received in such transaction); and the VWAP for purposes of Section 11.01 will be calculated based on the value of one unit of
Reference Property in a manner reasonably consistent with such definition as determined in good faith by the Board of Directors of the Company. 
 (c) The above provisions of this Section 11.04 shall similarly apply to successive Reorganization Events. 
 (d) If this Section 11.04 applies to any event or occurrence, Section 11.02 shall not apply in respect of such event or occurrence. 

(e) The Company shall not become a party to any Reorganization Event unless its terms are consistent with the foregoing. None of the
foregoing provisions shall affect the right of a Holder of Notes to convert the Notes as set forth in and subject to Section 11.01 prior to the effective time of such Reorganization Event. 

Section 11.05. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not be accountable with respect to
the validity or value (or the kind or amount) of any Ordinary Shares, or of any securities or property, which may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no
representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any cash or Ordinary Shares or stock certificates or other securities or property
upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 11. 
 Section 11.06. Shareholder Rights Plan. To the extent that the Company has a rights plan in effect upon conversion of the Notes into Ordinary Shares, the Holder will receive upon conversion of
the Notes in respect of which the Company has elected to deliver Ordinary Shares, if applicable, the rights under the rights plan, unless prior to any conversion, the rights have separated from the Ordinary Shares, in which case, and only in such
case, the Conversion Rate will be adjusted at the time of separation as if the Company distributed to all or substantially all holders of Ordinary Shares, shares of the Company’s Capital Stock, evidences of indebtedness or assets as described
in Section 11.02(d) (with such separation being deemed a Trigger Event for purposes of Section 11.02(d)), subject to readjustment in the event of the expiration, termination 

  
 43 

 
or redemption of such rights. For purposes of calculating the per share Fair Market Value of the shares of the Company’s Capital Stock, evidences of indebtedness or assets, including
securities, distributed with respect to each outstanding Ordinary Share under Section 11.02(d), any Ordinary Shares held by any Person who is ineligible to receive such distribution under the terms of the rights plan shall not be deemed
outstanding. The Company agrees that any rights plan adopted by the Company shall provide for the foregoing rights upon conversion of the Notes. Any distribution of rights or warrants pursuant to a rights plan that would allow Holders to receive
upon conversion, in addition to Ordinary Shares, the rights described therein with respect to such Ordinary Shares (unless such rights or warrants have separated from the Ordinary Shares) shall not constitute a distribution of rights or warrants
that would entitle Holders to an adjustment to the Conversion Rate. 
 Section 11.07. No Stockholder Rights. For the
avoidance of doubt, Holders of Notes will not have any rights as holders of Ordinary Shares (including voting rights and rights to receive any dividends or other distributions on the Ordinary Shares) if and until the Notes are converted into
Ordinary Shares. 
 Section 11.08. Withholding Taxes for Adjustments in Conversion Rate. If the Company pays
withholding taxes on behalf of a Holder as a result of an adjustment to the Conversion Rate, the Company may, at its option, set off such payments against payments of cash and Ordinary Shares on the Notes. 

Section 11.09. Issuer’s Conversion Option. 
 (a) At any time on or prior to September 1, 2015, the Company may elect to mandatorily convert some or all of the Notes at the then applicable Conversion Rate if the VWAP of the Ordinary Shares is
greater than or equal to 150% of the applicable Conversion Price for at least 20 Trading Days during any 30 consecutive Trading Day period ending within five Trading Days prior to the notice of conversion. In connection with any mandatory conversion
pursuant to this Section 11.09 prior to September 1, 2015, Holders will receive upon conversion, in addition to the consideration issuable upon conversion under Section 11.01, a payment in cash or Ordinary Shares (the “Coupon
Make Whole Payment”) for the Notes being converted in an amount equal to $157.50 per $1,000 principal amount of Notes converted. 
 (b) The Company may settle the Coupon Make Whole Payments in cash or in Ordinary Shares, at the Company’s election as specified in the notice described below. If the Company elects to settle the
Coupon Make Whole Payments in Ordinary Shares, the Company will deliver to each Holder of converted Notes a number of Ordinary Shares at settlement equal to the amount of the Coupon Make Whole Payment owed to such Holder divided by the average of
the VWAP of the Ordinary Shares for the 10 consecutive Trading Days next succeeding the mandatory conversion date. Delivery of the Coupon Make Whole Payments that the Company elects to pay in cash will be made concurrently with delivery of the other
consideration to be delivered upon conversion pursuant to Section 11.01. Delivery of the Coupon Make Whole Payments that the Company elects to pay in Ordinary Shares will be made as promptly as practicable following determination of the number
of Ordinary Shares to be delivered as set forth above, in the same manner as Ordinary Shares delivered in settlement of the conversion obligation (including with respect to cash in lieu of fractional shares) pursuant to Section 11.01.

  
 44 

 (c) If the Company elects to exercise its mandatory conversion right pursuant to this
Section 11.09, the Company, or, at its request, the Trustee in the name of and at the expense of the Company, will be required to deliver notice of conversion to Holders of Notes on or before the fifth Trading Days following the 30 consecutive
Trading Day period referenced in Section 11.09(a) above, in accordance with Section 10.02 of the Base Indenture (with copy to the Trustee, Conversion Agent and the Paying Agent). The conversion notice shall specify: 

(i) the conversion date for such mandatory conversion, which shall be not less than 20 nor more than 30 days following the
date of the notice of conversion; 
 (ii) the applicable Conversion Rate in effect on the date of the conversion
notice; 
 (iii) whether the Company will settle the conversion obligations with respect to the mandatory
conversion pursuant to Section 11.01(c)(i) or Section 11.01(c)(ii); 
 (iv) the amount of Notes the
Company is electing to convert; and 
 (v) whether the Company will be paying the Coupon Make Whole Payment, if
any, in cash or in Ordinary Shares. 
 Simultaneously with providing such notice, the Company will promptly publicly announce through a
reputable national newswire in the United States the relevant information in such notice and publish such information on its then existing website or through such other public medium as it may use at the time. 

(d) If the Company elects to convert less than all of the Notes then outstanding, the Trustee will select the Notes to be converted (in
principal amounts of $2,000 or an integral multiple of $1,000 in excess thereof) by lot, on a pro rata basis or by any other method the Trustee shall deem fair and appropriate, including any method required by DTC or any successor depositary (and in
such manner as is not prohibited by applicable legal requirements). If any Note is to be converted in part only, a new Note in principal amount equal to the unconverted principal portion will be issued.

 TERMS OF NOTES 

7.875% Senior Convertible Notes due 2042 
 This Note is one of a duly authorized issue of a series of Securities of the Company, titled as 7.875% Senior Convertible Notes due 2042 (herein called the “Notes”), issued and to be
issued under and pursuant to an Indenture dated as of August 21, 2012 (the “Base Indenture”), as amended and supplemented by a First Supplemental Indenture dated as of August 21, 2012 (the “First Supplemental
Indenture”); and the Base Indenture, as so amended and supplemented, herein called the “Indenture”), each between Vantage Drilling Company, a Cayman Islands exempted company (such corporation, and its successors and assigns
under the Indenture hereinafter referred to, being herein called the “Company”) and Wells Fargo Bank, National Association, as trustee (herein called the “Trustee”), to which Indenture and all indentures
supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. 

 

	 	1.	Interest 

 The Company, promises
to pay interest on the principal amount of this Note at the rate of 7.875% per annum. 
 The Company will pay interest
semiannually in arrears on March 1 and September 1 of each year (each, an “Interest Payment Date”), commencing March 1, 2013, to Holders of record on the immediately preceding February 15 and August 15.
Interest on the Notes will accrue from the most recent date to which interest has been paid on the Notes or, if no interest has been paid, from August 21, 2012. Interest will be computed on the basis of a 360-day year of twelve 30-day months.
Interest will cease to accrue on a Note, as provided in the Indenture, upon its maturity, conversion, redemption or repurchase. 
  

	 	2.	Method of Payment 

 By no later
than 11:00 a.m. (New York City time) on the date on which any principal of or interest on any Note is due and payable, the Company shall deposit with the Paying Agent money sufficient to pay such amount. The Company will pay principal, premium and
interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of Notes represented by a Global Note (including principal and interest) will be made by wire transfer of
immediately available funds to the accounts specified by The Depository Trust Company. The Company will pay principal of Definitive Notes at the office or agency designated by the Company for such purpose. Interest, on Definitive Notes will be
payable (i) to Holders having an aggregate principal amount of $5,000,000 or less, by check mailed to the Holders of these Notes and (ii) to Holders having an aggregate principal 

  
 A-3

 
amount of more than $5,000,000, either by check mailed to each Holder or, upon application by a Holder to the Registrar not later than the relevant record date, by wire transfer in immediately
available funds to that Holder’s account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Registrar to the contrary. 

 

	 	3.	Redemption 

 Subject to certain
conditions specified in the First Supplemental Indenture, the Notes will be redeemable, at the option of the Company, in whole at any time or in part from time to time, at any time on or after September 1, 2015 and at a price equal to 100% of
the principal amount of Notes to be redeemed, plus accrued and unpaid interest to but excluding the Redemption Date (unless the Redemption Date is between a Regular Record Date and the Interest Payment Date to which it relates, in which case the
Company will pay accrued and unpaid interest to the Holder of record on such Regular Record Date). 
  

	 	4.	Purchase by the Company at the Option of the Holder; Purchase at the Option of the Holder Upon a Termination of Trading 

(a) Subject to the terms and conditions of the Indenture, a Holder shall have the option to require the Company to purchase all or a
portion of its Notes held by such Holder on each of September 1, 2015 and September 1, 2017 at a Purchase Price specified in the First Supplemental Indenture. 
 (b) If a Termination of Trading shall occur at any time, each Holder shall have the right, at such Holder’s option and subject to the terms and conditions of the Indenture, to require the Company to
purchase all or a portion of its Notes at a Termination of Trading Purchase Price specified in the First Supplemental Indenture. 
  

	 	5.	Conversion 

 Subject to the
procedures for conversion set forth in the First Supplemental Indenture, a Holder may convert its Notes until 5:00 p.m., New York City time, on the Business Day immediately preceding September 1, 2042. 

(a) The initial Conversion Rate is 476.1905 Ordinary Shares per $1,000 principal amount of Notes, subject to adjustment in certain events
described in the First Supplemental Indenture. Upon conversion, the Company will either (i) deliver Ordinary Shares based on the Conversion Rate or (ii) pay cash and Ordinary Shares, if any, in each case as set forth in the First
Supplemental Indenture. The Company shall deliver cash in lieu of any fractional share of Ordinary Shares. Each Holder who elects to convert any of its Notes at the Holder’s option prior to September 1, 2017 will receive the Voluntary
Conversion Make Whole Payment as described in the Indenture. At any time on or prior to September 1, 2015, the Company may elect to mandatorily convert some or all of 

  
 A-4

 
the Notes at the then applicable Conversion Rate if the VWAP of the Ordinary Shares is greater than or equal to 150% of the applicable Conversion Price for at least 20 Trading Days during any 30
consecutive Trading Day period ending within five Trading Days prior to the notice of conversion and Holders will receive a Coupon Make Whole Payment for the Notes being converted as described in the Indenture. 

No payment or adjustment shall be made for dividends on the Ordinary Shares except as provided in the First Supplemental Indenture.

  

	 	6.	Denominations; Transfer; Exchange 

 The Notes are in registered form without coupons in denominations of principal amount of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance
with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the
transfer of or exchange of Notes (i) so selected for redemption or, if a portion of any Note is selected for redemption, the portion thereof selected for redemption; (ii) surrendered for conversion or, if a portion of any Note is
surrendered for conversion, the portion thereof surrendered for conversion; or (iii) in certificated form for a period of 15 days prior to sending a notice of redemption under Article 6 of the First Supplemental Indenture. 

 

	 	7.	Persons Deemed Owners 

 The
registered Holder of this Note may be treated as the owner of it for all purposes. 
  

	 	8.	Unclaimed Money 

 If money for
the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company, subject to applicable abandoned property laws. After any such payment, Holders entitled to the money must look
only to the Company and not to the Trustee for payment. 
  

	 	9.	Amendment, Waiver 

 Subject to
certain exceptions, the Indenture contains provisions permitting an amendment of the Indenture or the Notes with the written consent of the Holders of at least a majority in principal amount of the then outstanding Notes and the waiver of any Event
of Default (other than with respect to nonpayment or in respect of a provision that cannot be amended without the written consent of each Holder affected) or noncompliance with any provision with the written consent of the Holders of a majority in
principal amount of the then outstanding Notes. 

  
 A-5

 In addition, the Indenture permits an amendment of the Indenture or the Notes without the
consent of any Holder under certain circumstances specified in the Indenture. 
  

	 	10.	Defaults and Remedies 

 Subject
to the following paragraph, if an Event of Default specified in the Indenture occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Notes may declare all the Notes by notice to the Company to be due and
payable immediately. In addition, certain specified Events of Default will cause the Notes to become immediately due and payable without further action by the Holders. 
 Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives reasonable indemnity or security.
Subject to certain limitations, Holders of a majority in principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default or Event of Default (except a
Default or Event of Default in payment of principal or interest) if it determines that withholding notice is in their interest. 
  

	 	11.	Trustee Dealings with the Company 

 Subject to certain limitations set forth in the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with
and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 

 

	 	12.	No Recourse Against Others 

 An
incorporator, director, officer, employee, Affiliate or stockholder of the Company, solely by reason of this status, shall not have any liability for any obligations of the Company under the Notes, the Indenture or for any claim based on, in respect
of or by reason of such obligations or their creation. By accepting a Note, each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Notes. 

 

	 	13.	Authentication 

 This Note shall
not be valid until an authorized signatory of the Trustee manually authenticates this Note. 

  
 A-6

	 	14.	Abbreviations 

 Customary
abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entirety), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian) and
U/G/M/A (=Uniform Gift to Minors Act). 
  

	 	15.	CUSIP Numbers 

 Pursuant to a
recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to
Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon. 

 

	 	16.	Governing Law 

 This Note
shall be governed by, and construed in accordance with, the laws of the State of New York.

 THIS SIXTH SUPPLEMENTAL INDENTURE is made as of the 24th day of August, 2012, among AMERICAN FINANCIAL GROUP, INC., an Ohio
corporation, Great American Insurance Tower, 301 East Fourth Street, Cincinnati, Ohio 45202 (the “Company”), and U.S. BANK NATIONAL ASSOCIATION, (formerly known as Star Bank, N.A.) a national banking association, as trustee (the
“Trustee”). 
 WITNESSETH: 
 WHEREAS, the Company has heretofore entered into an Indenture, dated as of November 12, 1997, as supplemented by the Supplemental Indenture dated as of December 3, 1997, the Second Supplemental
Indenture dated as of February 3, 2004, the Third Supplement Indenture dated as of June 17, 2009, the Fourth Supplement Indenture dated as of September 27, 2010 and the Fifth Supplemental Indenture dated as of June 12, 2012
(collectively, the “Indenture”) with U.S. Bank National Association, as trustee; 
 WHEREAS, the Indenture is
incorporated herein by this reference; 
 WHEREAS, under the Indenture, a new series of Debt Securities may at any time be
established by the Board of Directors of the Company in accordance with the provisions of the Indenture and the conditions, limitations and restrictions on the terms of such series may be established by a supplemental indenture executed by the
Company and the Trustee; 
 WHEREAS, the Company proposes to create under the Indenture a new series of Debt Securities;

 WHEREAS, additional Debt Securities of other series hereafter established, except as may be limited in the Indenture as at
the time supplemented and modified, may be issued from time to time pursuant to the Indenture as at the time supplemented and modified, and that such series of Debt Securities hereafter established or any series of Debt Securities established prior
to the date hereof shall not be subject to the provisions of this Sixth Supplemental Indenture unless expressly provided in the Board Resolution, supplemental indenture or other documentation, as permitted by the Indenture, establishing such series
of Debt Securities; and 
 WHEREAS, all conditions necessary to authorize the execution and delivery of this Sixth Supplemental
Indenture and to make it a valid and binding obligation of the Company have been done or performed. 
 NOW, THEREFORE, in
consideration of the agreements and obligations set forth herein and for other good and valuable consideration, the sufficiency of which is hereby acknowledged, the parties hereto hereby agree as follows: 

ARTICLE I 
 5 3/4% SENIOR NOTES 
 Section 1.01 Establishment. There is hereby established a new series of Debt Securities to be issued under the Indenture, to be designated as the Company’s 5 3/4% Senior Notes due August 25, 2042 (the “Senior Notes”). 

There are to be authenticated and delivered Senior Notes, initially limited in aggregate principal amount of $125,000,000, and no further
Senior Notes shall be authenticated and delivered except as provided by Section 2.1, 3.5, 3.6, 9.6 and 11.7 of the Indenture; provided further, that the aggregate principal amount of the Senior Notes may be increased in the future, without the
consent of the Holders of 

  
 - 1 -

 
the Senior Notes, on the same terms and with the same CUSIP number as the Senior Notes, provided that such further Senior Notes are fungible for U.S. federal income tax purposes with such
previously issued Senior Notes. The Senior Notes shall be issued in definitive fully registered form. 
 The Senior Notes shall
be issued in the form of one Global Security in substantially the form set out in Exhibit A hereto. The U.S. Depositary with respect to the Senior Notes shall be The Depository Trust Company. 

The form of the Trustee’s Certificate of Authentication for the Senior Notes shall be in substantially the form set forth in Exhibit
B hereto. 
 Each Senior Note shall be dated the date of authentication thereof and shall bear interest from the date of
original issuance thereof or from the most recent Interest Payment Date to which interest has been paid or duly provided for. 

Section 1.02 Definitions. (a) The following defined terms used herein shall, unless the context otherwise requires, have
the meanings specified below. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture. 
 “Final Maturity” means August 25, 2042. 
 “Interest Payment
Date” means February 25, May 25, August 25 and November 25 of each year. 
 “Place of
Payment” means New York, New York. 
 “Regular Record Date” means
February 10, May 10, August 10 and November 10; as the case may be, next preceding the relevant Interest Payment Date. 
 Section 1.03 Payment of Principal and Interest. The entire outstanding principal amount of the Senior Notes shall be due and payable, unless accelerated, redeemed or required to be repurchased
pursuant to the Indenture, at Final Maturity. The unpaid principal amount of the Senior Notes shall bear interest at the rate of
5 3/4% per annum until paid or duly provided for. Interest shall be paid quarterly in arrears on each Interest Payment Date, commencing November 25, 2012, to the Person in whose name the Senior Notes
are registered on the Regular Record Date for such Interest Payment Date, provided that interest payable at Final Maturity will be paid to the Person to whom principal is payable. Any such interest that is not so punctually paid or duly provided for
will forthwith cease to be payable to the Holders on such Regular Record Date and may be paid as provided in Section 3.7 of the Indenture. 
 Payments of interest on the Senior Notes will include interest accrued to but excluding the respective Interest Payment Dates. Interest payments for the Senior Notes shall be computed and paid on the
basis of a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on the Senior Notes is not a Business Day, then a payment of the interest payable on such date will be made on the next succeeding day that is a
Business Day, except that, notwithstanding Section 1.13 of the Indenture, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and
effect as if made on the date the payment was originally payable. No interest will accrue due to any delay in payment on the amount so payable for the period from such Interest Payment Date to the date payment is made. 

Payment of the principal and interest due at Final Maturity of the Senior Notes shall be made at the office or agency of the Company
maintained for that purpose in the Place of Payment, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public 

  
 - 2 -

 
and private debts; provided, however, that, at the option of the Company, interest may be paid by check mailed to the address of the Person entitled thereto as such address shall appear in the
Security Register; provided, further, that payment to the U.S. Depositary or any successor depositary may be made by wire transfer to the account designated by the U.S. Depositary or such successor depositary in writing. 

Section 1.04 Denominations. The Senior Notes may be issued in denominations of $25.00, or any integral multiple of $25.00 in
excess thereof. 
 Section 1.05 Global Securities. The Senior Notes will be issued in the form of one or more Global
Securities registered in the name of the U.S. Depositary or its nominee. Except under the limited circumstances described below, Senior Notes represented by the Global Security will not be exchangeable for, and will not otherwise be issuable as,
Senior Notes in definitive form. The Global Securities described above may not be transferred except as a whole by the U.S. Depositary to a nominee of such U.S. Depositary or by a nominee of such U.S. Depositary to such depositary or another nominee
of such U.S. Depositary or by such U.S. Depositary or any other such nominee to a successor U.S. Depositary or a nominee of such successor U.S. Depositary. 
 Owners of beneficial interests in such a Global Security will not be considered the Holders thereof for any purpose under the Indenture, and no Global Security representing a Senior Note shall be
exchangeable, except for another Global Security of like denomination and tenor to be registered in the name of the U.S. Depositary or its nominee or to a successor U.S. Depositary or its nominee. The rights of Holders of such Global Security shall
be exercised only through the U.S. Depositary. 
 A Global Security shall be exchangeable for Senior Notes registered in the
names of Persons other than the U.S. Depositary or its nominee only as provided by Section 3.5 of the Indenture. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Senior Notes registered in
such names as the U.S. Depositary shall direct. 
 Section 1.06 Redemption at the Option of the Company. The Senior
Notes may not be redeemed prior to August 25, 2017. On or after August 25, 2017, the Company, at its option, may redeem the Senior Notes, in whole at any time or in part from time to time, at 100% of their principal amount, plus accrued
interest to, but excluding, the date of redemption. 
 Section 1.07 Governing Law. Section 1.12 of the
Indenture is hereby amended and restated to read in its entirety as follows: 
 “SECTION 1.12 Governing Law.

 THIS INDENTURE AND THE DEBT SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW
YORK WITHOUT REGARD TO THE CONFLICTS OF LAW RULES OF SUCH STATE. THIS INDENTURE IS SUBJECT TO THE PROVISIONS OF THE TRUST INDENTURE ACT OF 1939, AS AMENDED, THAT ARE REQUIRED TO BE PART OF THIS INDENTURE AND SHALL, TO THE EXTENT APPLICABLE, BE
GOVERNED BY SUCH PROVISIONS.” 
 Section 1.08 Registration, Registration of Transfer and Exchange.
Section 3.5 of the Indenture is hereby amended and restated to read in its entirety as follows: 
 “SECTION 3.5
Registration, Registration of Transfer and Exchange. The Company shall keep or cause to be kept for the Debt Securities of each series a register (the register maintained in such office being herein sometimes referred to as the “Debt
Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration, registration of transfer and exchange of Debt Securities. The Trustee is hereby initially appointed
“Debt Security Registrar” for such purposes. 

  
 - 3 -

 Upon surrender for registration of transfer of any Debt Security of any particular series at
the office or agency of the Company in a Place of Payment for that series, the Company shall execute, and the Trustee for the Debt Securities of each series shall authenticate and deliver, in the name of the designated transferee or transferees, one
or more new Debt Securities of any authorized denominations, and of a like Stated Maturity and of a like series and aggregate principal amount and with like terms and conditions. 

Except as set forth below, at the option of the Holder, Debt Securities of any particular series may be exchanged for other Debt
Securities of any authorized denominations, and of a like Stated Maturity and of a like series and aggregate principal amount and with like terms and conditions, upon surrender of the Debt Securities to be exchanged at such office or agency.
Whenever any Debt Securities are so surrendered for exchange, the Company shall execute, and the Trustee for such Debt Securities shall authenticate and deliver, the Debt Securities which the Holder making the exchange is entitled to receive.

 All Debt Securities issued upon any registration of transfer or exchange of Debt Securities shall be the valid obligations of
the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Debt Securities surrendered upon such registration of transfer or exchange. 

Every Debt Security presented or surrendered for registration of transfer or exchange shall (if so required by the Company or the Trustee
for such Debt Security) be duly endorsed, or be accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Debt Security Registrar for such series duly executed by the Holder thereof or his attorney duly
authorized in writing. 
 No service charge shall be made for any registration of transfer or exchange of Debt Securities, but
the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Debt Securities, other than exchanges pursuant to Section 3.4,
9.6, 11.3 or 11.7 not involving any transfer. 
 Notwithstanding any other provision of this Section, unless and until it is
exchanged in whole or in part for Debt Securities in definitive form, a Global Security representing all or a portion of the Debt Securities of a series may not be transferred except as a whole by the U.S. Depositary for such series to a nominee of
such U.S. Depositary or by a nominee of such U.S. Depositary to such depositary or another nominee of such U.S. Depositary or by such U.S. Depositary or any other such nominee to a successor U.S. Depositary for such series or a nominee of such
successor U.S. Depositary. 
 If at any time the U.S. Depositary for the Debt Securities of a series notifies the Company that
it is unwilling or unable to continue as U.S. Depositary for the Debt Securities of such series or if at any time the U.S. Depositary for Debt Securities of such series shall no longer be a clearing agency registered and in good standing under the
Exchange Act or other applicable statute or regulation, the Company shall appoint a successor U.S. Depositary for the Debt Securities of such series. If a successor U.S. Depositary for the Debt Securities is not appointed by the Company within 90
days after the Company receives such notice or becomes aware of such condition, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Debt Securities of such series, will
authenticate and deliver, Debt Securities of such series in definitive form in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global Security or
Securities. 

  
 - 4 -

 The Company may at any time and in its sole discretion determine that the Debt Securities of
any series issued in the form of one or more Global Securities shall no longer be represented by such Global Security or Securities. In such event, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and
delivery of definitive Debt Securities of such series, will authenticate and deliver, Debt Securities of such series in definitive form and in an aggregate principal amount equal to the principal amount of the Global Security or Securities
representing such series in exchange for such Global Security or Securities. 
 If the Debt Securities of any series shall have
been issued in the form of one or more Global Securities and if an Event of Default with respect to the Debt Securities of such series shall have occurred and be continuing, the Company will promptly execute, and the Trustee, upon receipt of a
Company Order for the authentication and delivery of definitive Debt Securities of such series, will authenticate and deliver Debt Securities of such series in definitive form and in an aggregate principal amount equal to the principal amount of the
Global Security or Securities representing such series in exchange for such Global Security or Securities. 
 The U.S.
Depositary for such series of Debt Securities may surrender a Global Security for such series of Debt Securities in exchange in whole or in part for Debt Securities of such series of like tenor and terms and in definitive form on such terms as are
acceptable to the Company and such U.S. Depositary. Thereupon, the Company shall execute and the Trustee shall authenticate and deliver, without charge: 
 (1) to each Person specified by the U.S. Depositary a new Debt Security or Securities of the same series, of like tenor and terms and of any authorized denomination as requested by such Person in an
aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the Global Security; and 

(2) to the U.S. Depositary a new Global Security in a denomination equal to the difference, if any, between the principal amount of the
surrendered Global Security and the aggregate principal amount of the Debt Securities delivered to Holders thereof. 
 Upon the
exchange of a Global Security for Debt Securities in definitive form, such Global Security shall be canceled by the Trustee. Definitive Debt Securities issued in exchange for a Global Security pursuant to this Section shall be registered in such
names and in such authorized denominations as the U.S. Depositary for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such definitive Debt
Securities to the Persons in whose names such Debt Securities are so registered.” 
 Section 1.09 Title; Payment
and Terms. The last paragraph of Section 3.1 of the Indenture is hereby amended and restated to read in its entirety as follows: 
 “All Debt Securities of any particular series shall be substantially identical except as to denomination, rate of interest, Stated Maturity and the date from which interest, if any, shall accrue, and
except as may otherwise be provided in or pursuant to such Board Resolution relating thereto. The terms of such Debt Securities, as set forth above, may be determined by the Company from time to time if so provided in or established pursuant to the
authority granted in a Board Resolution. Any of the terms of the Debt Securities, as set forth above, may be made dependent upon facts ascertainable outside the Board Resolution provided that the manner in which said facts shall operate upon the
terms is set forth in the Board Resolution. All Debt Securities of any one series need not be issued at the same time, and unless 

  
 - 5 -

 
otherwise provided, a series may be reopened, without notice to or the consent of the registered holders of such Debt Securities, for issuances of additional Debt Securities of such series. Such
additional Debt Securities will rank pari passu with the outstanding Debt Securities of such series in all material respects, or in all respects except for the issue date and public offering price or payment of interest accruing
prior to the issue date of such additional Debt Securities or except for the first payment of interest following the issue date of such additional Debt Securities, and so that such additional Debt Securities may be consolidated and form a single
series with the outstanding Debt Securities of such series and have the same terms as to status, redemption or otherwise as the outstanding Debt Securities of such series; provided that such additional Debt Securities are fungible for
U.S. federal income tax purposes with such previously issued Debt Securities” 
 Section 1.10 Mutilated,
Destroyed, Lost and Stolen Debt Securities. Section 3.6 of the Indenture is hereby amended and restated to read in its entirety as follows: 
 “SECTION 3.6 Mutilated, Destroyed, Lost and Stolen Debt Securities. If (i) any mutilated Debt Security is surrendered to the Trustee for such Debt Security, or the Company and the Trustee
for a Debt Security receive evidence to their satisfaction of the destruction, loss or theft of any Debt Security, and (ii) there is delivered to the Company, the Debt Security Registrar and such Trustee such security or indemnity as may be
reasonably required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or such Trustee that such Debt Security has been acquired by a bona fide purchaser, the Company shall execute
and upon its request such Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Debt Security or in exchange for such mutilated Debt Security, a new Debt Security of the same series and in a like principal amount and
of a like Stated Maturity and with like terms and conditions and bearing a number not contemporaneously outstanding. 
 In case
any such mutilated, destroyed, lost or stolen Debt Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Debt Security, pay such Debt Security (without surrender thereof except in the
case of a mutilated Debt Security) if the applicant for such payment shall furnish to the Company, the Debt Security Registrar and the Trustee for such Debt Security such security or indemnity as may be reasonably required by them to save each of
them harmless, and in case of destruction, loss or theft, evidence reasonably satisfactory to the Company and such Trustee and any agent of either of them of the destruction, loss or theft of such Debt Security and the ownership thereof. 

Upon the issuance of any new Debt Security under this Section, the Company may require the payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in relation thereto and any other expenses (including all fees and expenses of the Trustee and the Debt Security Registrar for such Debt Security) connected therewith. 

Every new Debt Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Debt Security or in
exchange for any mutilated Debt Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Debt Security shall be at any time enforceable by anyone, and shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all other Debt Securities of the same series, duly issued hereunder. 
 The provisions of this Section are exclusive and shall preclude (to the extent lawful) the assertion of any Holder of all other rights and remedies with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Debt Securities.” 

  
 - 6 -

 Section 1.11 Events of Default. Section 5.1 of the Indenture is hereby
amended and restated to read in its entirety as follows: 
 “SECTION 5.1 Events of Default. “Event of
Default” wherever used herein with respect to any particular series of Debt Securities, unless otherwise specified in the Debt Security or the Board Resolution with respect to that series of Debt Securities, means any one of the following
events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative
or governmental body): 
 (1) default in the payment of any installment of interest upon any Debt Security of that series when it
becomes due and payable, and continuance of such default for a period of 30 days; or 
 (2) default in the payment of the
principal of (or premium, if any, on) any Debt Security of that series at its Maturity; or 
 (3) default in the performance of,
or breach of, any covenant or warranty of the Company in respect of any Debt Security of that series contained in this Indenture or in such Debt Securities (other than a covenant or warranty a default in whose performance or whose breach is
elsewhere in this Section specifically dealt with or which expressly has been included in this Indenture solely for the benefit of Debt Securities of a series other than that series) or in the applicable Board Resolution under which such series is
issued as contemplated by Section 3.1 and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee for the Debt Securities of such series or to the
Company and such Trustee by the Holders of at least 25% in principal amount of the Outstanding Debt Securities of that series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a
“Notice of Default” hereunder; or 
 (4) if an event of default with respect to any other series of Debt Securities or
as defined in any mortgage, indenture, security agreement or other instrument under which there may be issued, or by which there may be secured or evidenced, any Indebtedness of the Company for money borrowed in excess of $10 million principal
amount, whether such Indebtedness now exists or shall hereafter be created, shall happen and, if such Indebtedness is not already matured in accordance with its terms, shall result in such Indebtedness becoming or being declared due and payable
prior to the date on which it would otherwise become due and payable, and such acceleration shall not have been rescinded or annulled or such Indebtedness shall not have been discharged, in either case, within a period of ten days after there has
been given, by registered or certified mail in the manner set forth in Section 1.5, to the Company by the Trustee for the Debt Securities of that particular series referred to in the first clause of this Section 5.1 or to the Company and
such Trustee by the Holders of at least 25% in principal amount of the Outstanding Debt Securities of that particular series referred to in the first clause of this Section 5.1 a written notice specifying such event of default and requiring the
Company to cause such acceleration to be rescinded or annulled or to cause such Indebtedness to be discharged and stating that such notice is a “Notice of Default” hereunder; provided, that if prior to the entry of judgment in favor of the
Trustee, such default under such indenture or instrument shall be remedied or cured by the Company or waived by the holders of such Indebtedness, then the Event of Default hereunder shall be deemed likewise to have been remedied, cured or waived;

Acceleration of Maturity; Rescission and Annulment. Section 5.2 of the Indenture is hereby amended and restated to read in its entirety as follows: 
 “SECTION 5.2 Acceleration of Maturity; Rescission and Annulment. If an Event of Default (other than an Event of Default specified in Section 5.1(6) or (7)) with respect to any particular
series of Debt Securities occurs and is continuing, then and in every such case either the Trustee for the Debt Securities of such series or the Holders of not less than 25% in principal amount of the Outstanding Debt Securities of that series may
declare the entire principal amount (or, in the case of Discounted Debt Securities, such lesser amount as may be provided for in the terms of that series) of all the Debt Securities of that series to be due and payable immediately, by a notice in
writing to the Company (and to such Trustee if given by Holders), and upon any such declaration of acceleration such principal or such lesser amount, as the case may be, together with accrued interest and all other amounts owing hereunder, shall
become immediately due and payable, without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived. 

  
 - 8 -

 If an Event of Default specified in Sections 5.1(6) or (7) occurs and is continuing,
such principal or such lesser amount, as the case may be, together with accrued interest and all other amounts owing hereunder, on the Debt Securities of that series shall become and be immediately due and payable without any declaration or other
act on the part of the Trustee or any Holder. 
 At any time after such a declaration of acceleration has been made and before a
judgment or decree for payment of the money due has been obtained by the Trustee for the Debt Securities of any series as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Debt Securities of that
series, by written notice to the Company and such Trustee, may rescind and annul such declaration and its consequences if: 
 (1)
the Company has paid or deposited with such Trustee a sum sufficient to pay 
 (A) all overdue interest on all Debt Securities of
that series; 
 (B) the principal of (and premium, if any, on) any Debt Securities of that series which have become due otherwise
than by such declaration of acceleration and interest thereon from the date such principal became due at a rate per annum equal to the rate borne by the Debt Securities of such series (or, in the case of Discounted Debt Securities, the Debt
Securities’ Yield to Maturity), to the extent that the payment of such interest shall be legally enforceable; 
 (C) to the
extent that payment of such interest is lawful, interest upon overdue interest at a rate per annum equal to the rate borne by the Debt Securities of such series (or, in the case of Discounted Debt Securities, the Debt Securities’ Yield to
Maturity); 
 (D) all sums paid or advanced by such Trustee hereunder and the reasonable compensation, expenses, disbursements
and advances of such Trustee, its agents and counsel and all other amounts due to such Trustee under; and 
 (2) all Events of
Default with respect to the Debt Securities of such series, other than the nonpayment of the principal of Debt Securities of that series which has become due solely by such acceleration, have been cured or waived as provided in Section 5.13. No
such rescission shall affect any subsequent default or impair any right consequent thereon.” 
 Section 1.13

 “SECTION 6.11 Acceptance of Appointment by Successor. 
 (a) Every such
successor Trustee appointed hereunder with respect to the Debt Securities of any series shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or
removal of the retiring Trustee shall become effective and such successor Trustee without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of its reasonable charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, subject to the lien provided for in Section 6.7.”

 (3) modify any of the provisions of
this Section or Section 5.13 or 10.7, except to increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Debt Security affected thereby;

the rights under this Indenture of the Holders of Debt Securities of any other series.

reasonable judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the Company from
discontinuing the operation and maintenance of any of its properties if such discontinuance is, in the reasonable judgment of the Company desirable in the conduct of its business and not disadvantageous in any material respect to the Holders.”

 Section 1.16 Corporate Existence. Section 10.6 of the Indenture is hereby amended and restated to read in
its entirety as follows:

indebtedness for borrowed money secured by a mortgage, pledge, lien or other encumbrance, directly or indirectly, upon any shares of the Voting Stock of a Restricted Subsidiary which shares are owned by the Issuer or its Restricted Subsidiaries

its entirety as follows:

3/4% Senior Notes Due August 25, 2042 

Principal Amount Per Senior Note: $25.00 
 American Financial Group, Inc., an Ohio corporation (hereinafter called the “Company”, which term includes any successor corporation under the Indenture referred to below), for value received,
hereby promises to pay to Cede & Co., or registered assigns, the principal amount of each Senior Note evidenced hereby (One Hundred Twenty Five Million Dollars ($125,000,000) in the aggregate) on August 25, 2042, and to pay interest
thereon from August 24, 2012 or from the most recent date to which interest has been paid or duly provided for, quarterly on February 25, May 25, August 25 and November 25 in each year (each, an “Interest
Payment Date”), commencing November 25, 2012, at the rate of 5 3/4% per annum, until the principal amount of each Senior Note evidenced hereby is paid or duly made available for
payment. Interest on the Senior Notes shall be calculated on the basis of a 360-day year consisting of twelve 30-day months. The interest so payable and punctually paid or duly provided for on any Interest Payment Date will, as provided in such
Indenture, be paid to the Person in whose name this certificate is registered at the close of business on the Regular Record Date for such interest, which shall be the February 10, May 10, August 10 and November 10
(whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to
the registered Holder hereof on the relevant Regular Record Date by virtue of having been such Holder, and may be paid to the Person in 

  
 A-1

 
whose name this certificate is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to
each Person in whose name a certificate evidencing Senior Notes (defined below) is registered not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Senior Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in such Indenture. 
 Payment of the principal of and the interest on the Senior Notes evidenced hereby will be made at the office or agency of the Company maintained for that purpose in the Place of Payment, in such coin or
currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that, at the option of the Company, interest may be paid by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register; provided, further, that payment to The Depository Trust Company (“DTC”) or any successor depositary may be made by wire transfer to the account designated by DTC or
such successor depositary in writing. 
 This certificate evidences part of a duly authorized issue of unsecured and
unsubordinated indebtedness of the Company (the “Debt Securities”) issued and to be issued in one or more series under an Indenture dated as of November 12, 1997 (herein called, together with all indentures supplemental thereto, the
“Indenture”) between the Company and U.S. Bank National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental
thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Company, the Trustee and the Holders of the Debt Securities, and of the terms upon which the Debt
Securities are, and are to be, authenticated and delivered. This certificate evidences Debt Securities of the series designated on the face hereof (each, a “Senior Note”), limited to $125,000,000; provided, that the aggregate principal
amount of the Senior Notes may be increased in the future, without the consent of the Holders of the Senior Notes, on the same terms and with the same CUSIP number as the Senior Notes, provided that such further Senior Notes are fungible for U.S.
federal income tax purposes with such previously issued Senior Notes. 
 The Senior Notes may not be redeemed prior to
August 25, 2017. On or after August 25, 2017, the Company, at its option, may redeem the Senior Notes, in whole at any time or in part from time to time, at 100% of their principal amount, plus accrued interest to, but excluding, the date
of redemption. 
 Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date
to each Person in whose name a certificate evidencing Senior Notes to be redeemed is registered at its registered address. Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue
on such Senior Notes called for redemption. 
 Except as provided above, the Senior Notes are not redeemable by the Company
prior to maturity and are not subject to any sinking fund. If an Event of Default with respect to the Senior Notes shall occur and be continuing, the principal amount of the Senior Notes shall be immediately, or may be declared, as appropriate, due
and payable in the manner and with the effect provided in the Indenture. 
 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 of the Securities of each series issued under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of each series affected thereby. The Indenture also contains provisions permitting the Holders of specified percentages in
aggregate principal amount of the Securities of any series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their 

  
 A-2

 
consequences. Any such consent or waiver by the Holder of this certificate shall be conclusive and binding upon such Holder and upon all future Holders of this certificate and of any Senior Notes
evidenced by a certificate 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 certificate. 

No reference herein to the Indenture and no provision of this certificate or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and interest on the Senior Notes evidenced by this certificate, at the times, place and rate, and in the coin or currency, herein and in the Indenture prescribed. 

As provided in the Indenture and subject to certain limitations set forth therein and in this certificate, the transfer of the Senior
Notes evidenced by this certificate may be registered on the Security Register upon surrender of this certificate for registration of transfer at the office or agency of the Company maintained for the purpose in any place where the principal of and
interest on the Senior Notes are payable, duly endorsed by, or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or by his attorney duly
authorized in writing, and thereupon one or more new certificates evidencing Senior Notes of authorized denominations, and of a like series and aggregate principal amount, and with like terms and conditions will be issued to the designated
transferee or transferees. 
 The Senior Notes are issuable only in registered form without coupons in denominations of $25.00,
or any integral multiple of $25.00 in excess thereof, all as more fully provided in the Indenture. As provided in the Indenture, and subject to certain limitations set forth in the Indenture, and in this certificate, this certificate is exchangeable
for a like aggregate principal amount of Senior Notes of this series in different authorized denominations, as requested by the Holders 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, other than in certain cases provided in the Indenture. 
 Prior to due presentment of this certificate for
registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this certificate is registered as the owner of the Senior Notes evidenced hereby for all the purpose of receiving
payment of principal of and (subject to Section 3.7 of the Indenture) interest, if any, on these Senior Note and for all purposes whatsoever, whether or not such Senior Notes be overdue, and neither the Company, the Trustee nor any such agent
shall be affected by notice to the contrary. 
 This certificate shall be governed by and construed in accordance with the laws
of the State of New York without regard to the conflicts of laws rules of such state. 
 All terms used in this certificate
which are defined in the Indenture shall have the meanings assigned to them in the Indenture. 
 Unless the certificate of
authentication hereon has been executed by or on behalf of the Trustee under the Indenture by the manual signature of one of its authorized signatories, this certificate shall not be entitled to any benefits under the Indenture or be valid or
obligatory for any purpose.
