of and the interest on the Securities of any series, as well as any premium thereon in case of redemption thereof prior to maturity, shall be payable in the coin or currency of the United States of America that at the time is legal tender for public
and private debt, at the office or agency of the Company maintained for that purpose. Each Security shall be dated the date of its authentication. Interest on the Securities shall be computed on the basis of a 360-day year composed of
twelve 30-day months. 
 The interest installment on any Security that is payable, and is punctually paid or duly provided for, on any
Interest Payment Date for Securities of that series shall be paid to the Person in whose name said Security (or one or more Predecessor Securities) is registered at the close of business on the regular record date for such interest
installment. In the event that any Security of a particular series or portion thereof is called for redemption and the redemption date is subsequent to a regular record date with respect to any Interest Payment Date and prior to such Interest
Payment Date, interest on such Security will be paid upon presentation and surrender of such Security as provided in Section 3.03. 

Any interest on any Security that is payable, but is not punctually paid or duly provided for, on any Interest Payment Date for Securities of
the same series (herein called “Defaulted Interest”) shall forthwith cease to be payable to the registered holder on the relevant regular record date by virtue of having been such holder; and such Defaulted Interest shall be paid by the
Company, at its election, as provided in clause (1) or clause (2) below: 
 (1) The Company may make payment of any Defaulted
Interest on Securities to the Persons in whose names such Securities (or their respective Predecessor Securities) are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in
the following manner: the Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee
an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall 

  
 6 

 
make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to
such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a special record date for the payment of such Defaulted Interest which shall not be more than 15 nor less than 10 days prior to the date of the proposed payment
and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such special record date and, in the name and at the expense of the Company, shall cause notice
of the proposed payment of such Defaulted Interest and the special record date therefor to be mailed, first class postage prepaid, to each Securityholder at his or her address as it appears in the Security Register (as hereinafter defined), not less
than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names
such Securities (or their respective Predecessor Securities) are registered on such special record date. 
 (2) The Company may make payment
of any Defaulted Interest on any Securities in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after
notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 

Unless otherwise set forth in a Board Resolution or one or more indentures supplemental hereto establishing the terms of any series of
Securities pursuant to Section 2.01 hereof, the term “regular record date” as used in this Section with respect to a series of Securities and any Interest Payment Date for such series shall mean either the fifteenth day of the
month immediately preceding the month in which an Interest Payment Date established for such series pursuant to Section 2.01 hereof shall occur, if such Interest Payment Date is the first day of a month, or the first day of the month in which
an Interest Payment Date established for such series pursuant to Section 2.01 hereof shall occur, if such Interest Payment Date is the fifteenth day of a month, whether or not such date is a Business Day. 

Subject to the foregoing provisions of this Section, each Security of a series delivered under this Indenture upon transfer of or in exchange
for or in lieu of any other Security of such series shall carry the rights to interest accrued and unpaid, and to accrue, that were carried by such other Security. 

Section 2.04 Execution and Authentications. 

The Securities shall be signed on behalf of the Company by one of its Officers. Signatures may be in the form of a manual or facsimile
signature. 
 The Company may use the facsimile signature of any Person who shall have been an Officer, notwithstanding the fact that at the
time the Securities shall be authenticated and delivered or disposed of such Person shall have ceased to be such an officer of the Company. The Securities may contain such notations, legends or endorsements required by law, stock exchange
rule or usage. Each Security shall be dated the date of its authentication by the Trustee. 
 A Security shall not be valid until
authenticated manually by an authorized signatory of the Trustee, or by an Authenticating Agent. Such signature shall be conclusive evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the
holder is entitled to the benefits of this Indenture. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for
authentication, together with a written order of the Company for the authentication and delivery of such Securities, signed by an Officer, and the Trustee in accordance with such written order shall authenticate and deliver such Securities. 

In authenticating such Securities and accepting the additional responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, if requested, and (subject to Section 7.01) shall be fully protected in relying upon, an Opinion of Counsel stating that the form and terms thereof have been established in conformity with the provisions of
this Indenture. 
 The Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this
Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner that is not reasonably acceptable to the Trustee.

 Section 2.05 Registration of Transfer and Exchange. 

(1) Securities of any series may be exchanged upon presentation thereof at the office or agency of the Company designated for such purpose, for
other Securities of such series of authorized denominations, and for a like aggregate principal amount, upon payment of a sum sufficient to cover any tax or other governmental charge in relation thereto, all as provided in this Section. In
respect of any Securities so surrendered for exchange, the Company shall execute, the Trustee shall authenticate and such office or agency shall deliver in exchange therefor the Security or Securities of the same series that the Securityholder
making the exchange shall be entitled to receive, bearing numbers not contemporaneously outstanding. 
 (2) The Company shall keep, or cause
to be kept, at its office or agency designated for such purpose a register or registers (herein referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall register the
Securities and the transfers of Securities as in this Article provided and which at all reasonable times shall be open for inspection by the Trustee. The registrar for the purpose of registering Securities and transfer of Securities as
herein provided shall be appointed as authorized by Board Resolution (the “Security Registrar”). 
 Upon surrender for transfer of
any Security at the office or agency of the Company designated for such purpose, the Company shall execute, the Trustee shall authenticate and such office or agency shall deliver in the name of the transferee or transferees a new Security or
Securities of the same series as the Security presented for a like aggregate principal amount. 
 All Securities presented or surrendered
for exchange or registration of transfer, as provided in this Section, shall be accompanied (if so required by the Company or the Security Registrar) by a written instrument or instruments of transfer, in form satisfactory to the Company or the
Security Registrar, duly executed by the registered holder or by such holder’s duly authorized attorney in writing. 
 (3) Except as
provided pursuant to Section 2.01 pursuant to a Board Resolution, and set forth in an Officer’s Certificate, or established in one or more indentures supplemental to this Indenture, no service charge shall be made for any exchange or
registration of transfer of Securities, or issue of new Securities in case of partial redemption of any series, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge in relation thereto, other than
exchanges pursuant to Section 2.06, Section 3.03(2) and Section 9.04 not involving any transfer. 
 (4) The Company shall
not be required (i) to issue, exchange or register the transfer of any Securities during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of less than all the Outstanding Securities
of the same series and ending at the close of business on the day of such mailing, nor (ii) to register the transfer of or exchange any Securities of any series or portions thereof called for redemption, other than the unredeemed portion of any
such Securities being redeemed in part. The provisions of this Section 2.05 are, with respect to any Global Security, subject to Section 2.11 hereof. 

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under
this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among depositary participants or beneficial owners of interests in any Global Security) other than to require
delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with
the express requirements hereof. 
 Section 2.06 Temporary Securities. 

Pending the preparation of definitive Securities of any series, the Company may execute, and the Trustee shall authenticate and deliver,
temporary Securities (printed, lithographed or typewritten) of any authorized denomination. Such temporary Securities shall be substantially in the form of the definitive Securities in lieu of which they are issued, but with such omissions,
insertions and variations as may be appropriate for temporary Securities, all as may be determined by the Company. Every temporary Security of any series shall be executed by the Company and be authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with like effect, as the definitive Securities of such series. Without unnecessary delay the Company will 

  
 8 

 
execute and will furnish definitive Securities of such series and thereupon any or all temporary Securities of such series may be surrendered in exchange therefor (without charge to the holders),
at the office or agency of the Company designated for the purpose, and the Trustee shall authenticate and such office or agency shall deliver in exchange for such temporary Securities an equal aggregate principal amount of definitive Securities of
such series, unless the Company advises the Trustee to the effect that definitive Securities need not be executed and furnished until further notice from the Company. Until so exchanged, the temporary Securities of such series shall be entitled
to the same benefits under this Indenture as definitive Securities of such series authenticated and delivered hereunder. 

Section 2.07 Mutilated, Destroyed, Lost or Stolen Securities. 

In case any temporary or definitive Security shall become mutilated or be destroyed, lost or stolen, the Company (subject to the next
succeeding sentence) shall execute, and upon the Company’s request the Trustee (subject as aforesaid) shall authenticate and deliver, a new Security of the same series, bearing a number not contemporaneously outstanding, in exchange and
substitution for the mutilated Security, or in lieu of and in substitution for the Security so destroyed, lost or stolen. In every case the applicant for a substituted Security shall furnish to the Company and the Trustee such security or
indemnity as may be required by them to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and the Trustee evidence to their satisfaction of the destruction, loss or theft of
the applicant’s Security and of the ownership thereof. The Trustee may authenticate any such substituted Security and deliver the same upon the written request or authorization of any officer of the Company. Upon the issuance of any
substituted Security, 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 the fees and expenses of the Trustee) connected
therewith. 
 In case any Security that has matured or is about to mature shall become mutilated or be destroyed, lost or stolen, the
Company may, instead of issuing a substitute Security, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Security) if the applicant for such payment shall furnish to the Company and the Trustee
such security or indemnity as they may require to save them harmless, and, in case of destruction, loss or theft, evidence to the satisfaction of the Company and the Trustee of the destruction, loss or theft of such Security and of the ownership
thereof. 
 Every replacement Security issued pursuant to the provisions of this Section shall constitute an additional contractual
obligation of the Company whether or not the mutilated, destroyed, lost or stolen Security shall be found at any time, or be enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and
all other Securities of the same series duly issued hereunder. All Securities shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities, and shall preclude (to the extent lawful) any and all other rights or remedies, notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender. 
 Section 2.08 Cancellation. 

All Securities surrendered for the purpose of payment, redemption, exchange or registration of transfer shall, if surrendered to the Company or
any paying agent, be delivered to the Trustee for cancellation, or, if surrendered to the Trustee, shall be cancelled by it, and no Securities shall be issued in lieu thereof except as expressly required or permitted by any of the provisions of this
Indenture. On request of the Company at the time of such surrender, the Trustee shall deliver to the Company canceled Securities held by the Trustee. In the absence of such request the Trustee may dispose of canceled Securities in
accordance with its standard procedures and deliver a certificate of disposition to the Company. If the Company shall otherwise acquire any of the Securities, however, such acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Securities unless and until the same are delivered to the Trustee for cancellation. 
 Section 2.09
Benefits of Indenture. 
 Nothing in this Indenture or in the Securities, express or implied, shall give or be construed to give to any
Person, other than the parties hereto and the holders of the Securities (and, with respect to the provisions of Article Fourteen, the holders of any indebtedness of the Company to which the Securities of any series are subordinated) any legal
or equitable right, remedy or claim under or in respect of this Indenture, or under any 

  
 9 

 
covenant, condition or provision herein contained; all such covenants, conditions and provisions being for the sole benefit of the parties hereto and of the holders of the Securities (and, with
respect to the provisions of Article Fourteen, the holders of any indebtedness of the Company to which the Securities of any series are subordinated). 

Section 2.10 Authenticating Agent. 

So long as any of the Securities of any series remain Outstanding there may be an Authenticating Agent for any or all such series of Securities
which the Trustee shall have the right to appoint. Said Authenticating Agent shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon exchange, transfer or partial redemption thereof, and
Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. All references in this Indenture to the authentication of
Securities by the Trustee shall be deemed to include authentication by an Authenticating Agent for such series. Each Authenticating Agent shall be acceptable to the Company and shall be a corporation that has a combined capital and surplus, as
most recently reported or determined by it, sufficient under the laws of any jurisdiction under which it is organized or in which it is doing business to conduct a trust business, and that is otherwise authorized under such laws to conduct such
business and is subject to supervision or examination by federal or state authorities. If at any time any Authenticating Agent shall cease to be eligible in accordance with these provisions, it shall resign immediately. 

Any Authenticating Agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee
may at any time (and upon request by the Company shall) terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Company. Upon resignation, termination or cessation of
eligibility of any Authenticating Agent, the Trustee may appoint an eligible successor Authenticating Agent acceptable to the Company. Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with
all the rights, powers and duties of its predecessor hereunder as if originally named as an Authenticating Agent pursuant hereto. 

Section 2.11 Global Securities. 

(1) If the Company shall establish pursuant to Section 2.01 that the Securities of a particular series are to be issued as a Global
Security, then the Company shall execute and the Trustee shall, in accordance with Section 2.04, authenticate and deliver, a Global Security that (i) shall represent, and shall be denominated in an amount equal to the aggregate principal
amount of, all of the Outstanding Securities of such series, (ii) shall be registered in the name of the Depositary or its nominee, (iii) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instruction
and (iv) shall bear a legend substantially to the following effect: “Except as otherwise provided in Section 2.11 of the Indenture, this Security may be transferred, in whole but not in part, only to another nominee of the Depositary
or to a successor Depositary or to a nominee of such successor Depositary.” 
 (2) Notwithstanding the provisions of Section 2.05,
the Global Security of a series may be transferred, in whole but not in part and in the manner provided in Section 2.05, only to another nominee of the Depositary for such series, or to a successor Depositary for such series selected or
approved by the Company or to a nominee of such successor Depositary. 
 (3) If at any time the Depositary for a series of the Securities
notifies the Company that it is unwilling or unable to continue as Depositary for such series or if at any time the Depositary for such series shall no longer be registered or in good standing under the Exchange Act, or other applicable statute or
regulation, and a successor Depositary for such series is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such condition, as the case may be, or if an Event of Default has occurred and is
continuing and the Company has received a request from the Depositary or from the Trustee, this Section 2.11 shall no longer be applicable to the Securities of such series and the Company will execute, and subject to Section 2.04, the
Trustee will authenticate and deliver the Securities of such series in definitive registered form without coupons, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the Global Security of such series
in exchange for such Global Security. In addition, the Company may at any time determine that the Securities of any series shall no longer be represented by a Global Security and that the provisions of this Section 2.11 shall no longer
apply to the Securities of such series. In such event the Company will execute and, subject to Section 2.04, the Trustee, upon receipt of an Officer’s Certificate evidencing such determination by the

  
 10 

 
Company, will authenticate and deliver the Securities of such series in definitive registered form without coupons, in authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Security of such series in exchange for such Global Security. Upon the exchange of the Global Security for such Securities in definitive registered form without coupons, in authorized denominations, the Global
Security shall be canceled by the Trustee. Such Securities in definitive registered form issued in exchange for the Global Security pursuant to this Section 2.11(3) shall be registered in such names and in such authorized
denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to the Depositary for delivery to the Persons in whose names
such Securities are so registered. 
 ARTICLE 3 

REDEMPTION OF SECURITIES AND SINKING FUND PROVISIONS 

Section 3.01 Redemption. 

The Company may redeem the Securities of any series issued hereunder on and after the dates and in accordance with the terms established for
such series pursuant to Section 2.01 hereof. 
 Section 3.02 Notice of Redemption. 

(1) In case the Company shall desire to exercise such right to redeem all or, as the case may be, a portion of the Securities of any series in
accordance with any right the Company reserved for itself to do so pursuant to Section 2.01 hereof, the Company shall, or shall cause the Trustee to, give notice of such redemption to holders of the Securities of such series to be redeemed by
mailing, first class postage prepaid, a notice of such redemption not less than 30 days and not more than 90 days before the date fixed for redemption of that series to such holders at their last addresses as they shall appear upon the Security
Register, unless a shorter period is specified in the Securities to be redeemed. Any notice that is mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the registered holder receives the
notice. In any case, failure duly to give such notice to the holder of any Security of any series designated for redemption in whole or in part, or any defect in the notice, shall not affect the validity of the proceedings for the redemption of
any other Securities of such series or any other series. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the
Company shall furnish the Trustee with an Officer’s Certificate evidencing compliance with any such restriction. 
 Each such notice of
redemption shall specify the date fixed for redemption and the redemption price at which Securities of that series are to be redeemed, and shall state that payment of the redemption price of such Securities to be redeemed will be made at the office
or agency of the Company, upon presentation and surrender of such Securities, that interest accrued to the date fixed for redemption will be paid as specified in said notice, that from and after said date interest will cease to accrue and that the
redemption is from a sinking fund, if such is the case. If less than all the Securities of a series are to be redeemed, the notice to the holders of Securities of that series to be redeemed in part shall specify the particular Securities to be
so redeemed. 
 In case any Security is to be redeemed in part only, the notice that relates to such Security shall state the portion of the
principal amount thereof to be redeemed, and shall state that on and after the redemption date, upon surrender of such Security, a new Security or Securities of such series in principal amount equal to the unredeemed portion thereof will be issued.

 (2) If less than all the Securities of a series are to be redeemed, the Company shall give the Trustee at least 45 days’ notice
(unless a shorter notice shall be satisfactory to the Trustee) in advance of the date fixed for redemption as to the aggregate principal amount of Securities of the series to be redeemed, and thereupon the Trustee shall select, by lot or in such
other manner as it shall deem appropriate and fair in its discretion and that may provide for the selection of a portion or portions (equal to one thousand U.S. dollars ($1,000) or any integral multiple thereof) of the principal amount of such
Securities of a denomination larger than $1,000, the Securities to be redeemed and shall thereafter promptly notify the Company in writing of the numbers of the Securities to be redeemed, in whole or in part. The Company may, if and whenever it
shall so elect, by delivery of instructions signed on its behalf by an Officer, instruct the Trustee or any paying agent to call all or any part of the Securities of 

  
 11 

 
a particular series for redemption and to give notice of redemption in the manner set forth in this Section, such notice to be in the name of the Company or its own name as the Trustee or such
paying agent may deem advisable. In any case in which notice of redemption is to be given by the Trustee or any such paying agent, the Company shall deliver or cause to be delivered to, or permit to remain with, the Trustee or such paying
agent, as the case may be, such Security Register, transfer books or other records, or suitable copies or extracts therefrom, sufficient to enable the Trustee or such paying agent to give any notice by mail that may be required under the provisions
of this Section. 
 Section 3.03 Payment Upon Redemption. 

(1) If the giving of notice of redemption shall have been completed as above provided, the Securities or portions of Securities of the series
to be redeemed specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable redemption price, together with interest accrued to the date fixed for redemption and interest on such
Securities or portions of Securities shall cease to accrue on and after the date fixed for redemption, unless the Company shall default in the payment of such redemption price and accrued interest with respect to any such Security or portion
thereof. On presentation and surrender of such Securities on or after the date fixed for redemption at the place of payment specified in the notice, said Securities shall be paid and redeemed at the applicable redemption price for such series,
together with interest accrued thereon to the date fixed for redemption (but if the date fixed for redemption is an interest payment date, the interest installment payable on such date shall be payable to the registered holder at the close of
business on the applicable record date pursuant to Section 2.03). 
 (2) Upon presentation of any Security of such series that is to be
redeemed in part only, the Company shall execute and the Trustee shall authenticate and the office or agency where the Security is presented shall deliver to the holder thereof, at the expense of the Company, a new Security of the same series of
authorized denominations in principal amount equal to the unredeemed portion of the Security so presented. 
 Section 3.04 Sinking
Fund. 
 The provisions of Sections 3.04, 3.05 and 3.06 shall be applicable to any sinking fund for the retirement of Securities of a
series, except as otherwise specified as contemplated by Section 2.01 for Securities of such series. 
 The minimum amount of any
sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of any series
is herein referred to as an “optional sinking fund payment”. If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 3.05. Each
sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series. 

Section 3.05 Satisfaction of Sinking Fund Payments with Securities. 

The Company (i) may deliver Outstanding Securities of a series and (ii) may apply as a credit Securities of a series that have been
redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part
of any sinking fund payment with respect to the Securities of such series required to be made pursuant to the terms of such Securities as provided for by the terms of such series, provided that such Securities have not been previously so
credited. Such Securities shall be received and credited for such purpose by the Trustee at the redemption price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly. 
 Section 3.06 Redemption of Securities for Sinking Fund. 

Not less than 45 days prior to each sinking fund payment date for any series of Securities (unless a shorter period shall be satisfactory to
the Trustee), the Company will deliver to the Trustee an Officer’s Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of the series, the portion thereof, if any, that is to be
satisfied by delivering and crediting Securities of that series pursuant to Section 3.05 and the basis for such credit and will, together with such Officer’s Certificate, deliver to the Trustee

  
 12 

 
any Securities to be so delivered. Not less than 30 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date
in the manner specified in Section 3.02 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 3.02. Such notice having been duly given, the redemption
of such Securities shall be made upon the terms and in the manner stated in Section 3.03. 
 ARTICLE 4 

COVENANTS 

Section 4.01 Payment of Principal, Premium and Interest. 

The Company will duly and punctually pay or cause to be paid the principal of (and premium, if any) and interest on the Securities of that
series at the time and place and in the manner provided herein and established with respect to such Securities. Payments of principal on the Securities may be made at the time provided herein and established with respect to such Securities by U.S.
dollar check drawn on and mailed to the address of the Securityholder entitled thereto as such address shall appear in the Security Register, or U.S. dollar wire transfer to, a U.S. dollar account if such Securityholder shall have furnished wire
instructions to the Trustee no later than 15 days prior to the relevant payment date. Payments of interest on the Securities may be made at the time provided herein and established with respect to such Securities by U.S. dollar check mailed to the
address of the Securityholder entitled thereto as such address shall appear in the Security Register, or U.S. dollar wire transfer to, a U.S. dollar account if such Securityholder shall have furnished wire instructions in writing to the Security
Registrar and the Trustee no later than 15 days prior to the relevant payment date. 
 Section 4.02 Maintenance of Office or Agency.

 So long as any series of the Securities remain Outstanding, the Company agrees to maintain an office or agency with respect to each
such series and at such other location or locations as may be designated as provided in this Section 4.02, where (i) Securities of that series may be presented for payment, (ii) Securities of that series may be presented as herein
above authorized for registration of transfer and exchange, and (iii) notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be given or served, such designation to continue with respect to
such office or agency until the Company shall, by written notice signed by any officer authorized to sign an Officer’s Certificate and delivered to the Trustee, designate some other office or agency for such purposes or any of them. If at
any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, notices and demands may be made or served at the Corporate Trust Office of the Trustee,
and the Company hereby appoints the Trustee as its agent to receive all such presentations, notices and demands. The Company initially appoints the Corporate Trust Office of the Trustee as its paying agent with respect to the Securities. 

Section 4.03 Paying Agents. 

(1) If the Company shall appoint one or more paying agents for all or any series of the Securities, other than the Trustee, the Company will
cause each such paying agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section: 

(a) that it will hold all sums held by it as such agent for the payment of the principal of (and premium, if any) or interest on the
Securities of that series (whether such sums have been paid to it by the Company or by any other obligor of such Securities) in trust for the benefit of the Persons entitled thereto; 

(b) that it will give the Trustee notice of any failure by the Company (or by any other obligor of such Securities) to make any payment of the
principal of (and premium, if any) or interest on the Securities of that series when the same shall be due and payable; 
 (c) that it will,
at any time during the continuance of any failure referred to in the preceding paragraph (a)(2) above, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such paying agent; and 

  
 13 

 (d) that it will perform all other duties of paying agent as set forth in this Indenture. 

(2) If the Company shall act as its own paying agent with respect to any series of the Securities, it will on or before each due date of the
principal of (and premium, if any) or interest on Securities of that series, set aside, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay such principal (and premium, if any) or interest so becoming
due on Securities of that series until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of such action, or any failure (by it or any other obligor on such Securities) to take
such action. Whenever the Company shall have one or more paying agents for any series of Securities, it will, prior to each due date of the principal of (and premium, if any) or interest on any Securities of that series, deposit with the paying
agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such paying agent is the Trustee)
the Company will promptly notify the Trustee of this action or failure so to act. 
 (3) Notwithstanding anything in this Section to the
contrary, (i) the agreement to hold sums in trust as provided in this Section is subject to the provisions of Section 11.05, and (ii) the Company may at any time, for the purpose of obtaining the satisfaction and discharge of
this Indenture or for any other purpose, pay, or direct any paying agent to pay, to the Trustee all sums held in trust by the Company or such paying agent, such sums to be held by the Trustee upon the same terms and conditions as those upon which
such sums were held by the Company or such paying agent; and, upon such payment by the Company or any paying agent to the Trustee, the Company or such paying agent shall be released from all further liability with respect to such money.

ARTICLE 5 

SECURITYHOLDERS’ LISTS AND REPORTS BY THE COMPANY AND THE TRUSTEE 

Section 5.01 Company to Furnish Trustee Names and Addresses of Securityholders. 

The Company will furnish or cause to be furnished to the Trustee (a) within 15 days after each regular record date (as defined in
Section 2.03) a list, in such form as the Trustee may reasonably require, of the names and addresses of the holders of each series of Securities as of such regular record date, provided that the Company shall not be obligated to furnish or
cause to furnish such list at any time that the list shall not differ in any respect from the most recent list furnished to the Trustee by the Company and (b) at such other times as the Trustee may request in writing within 30 days after the
receipt by the Company of any such request, a list of similar form and content as of a date not more than 15 days prior to the time such list is furnished; provided, however, that, in either case, no such list need be furnished for any series for
which the Trustee shall be the Security Registrar. 
 Section 5.02 Preservation Of Information; Communications With Securityholders.

 (1) The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of
the holders of Securities contained in the most recent list furnished to it as provided in Section 5.01 and as to the names and addresses of holders of Securities received by the Trustee in its capacity as Security Registrar (if acting in such
capacity) 
 (2) The Trustee may destroy any list furnished to it as provided in Section 5.01 upon receipt of a new list so furnished.

  
 14 

 (3) Securityholders may communicate as provided in Section 312(b) of the Trust

Trust Indenture Act in accordance with the provisions of Section 312(b) of the Trust Indenture Act. 
 Section 5.03
Reports by the Company. 
 (1) The Company covenants and agrees to provide (which delivery may be via electronic mail) to the Trustee
within 30 days, after the Company files the same with the Commission, copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may from time to time by
rules and regulations prescribe) that the Company is required to file with the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act; provided, however, the Company shall not be required to deliver to the Trustee
any materials for which the Company has sought and received confidential treatment by the Commission; and provided further, that so long as such filings by the Company are available on the Commission’s Electronic Data Gathering, Analysis and
Retrieval System (EDGAR), or Interactive Data Electronic Applications (IDEA), or any successor system, such filings shall be deemed to have been filed with the Trustee for purposes hereof without any further action required by the Company; provided
that an electronic link to such filing, together with an electronic notice of such filing have been sent to the Trustee. For the avoidance of doubt, a failure by the Company to file annual reports, information and other reports with the SEC
within the time period prescribed thereof by the Commission shall not be deemed a breach of this Section 5.03. 
 (2) Delivery of
reports, information and documents to the Trustee under Section 5.03 is for informational purposes only and the information and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained
therein, or determinable from information contained therein including the Company’s compliance with any of their covenants thereunder (as to which the Trustee is entitled to rely exclusively on an Officer’s Certificate). 

Section 5.04 Reports by the Trustee.

securities exchange upon which any Securities are listed (if so listed) and also with the Commission. The Company agrees to notify the Trustee when any Securities become listed on any securities exchange. 

ARTICLE 6 
 REMEDIES OF
THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT 
 Section 6.01 Events of Default. 

(1) Whenever used herein with respect to Securities of a particular series, “Event of Default” means any one or more of the following
events that has occurred and is continuing: 
 (a) the Company defaults in the payment of any installment of interest upon any of the
Securities of that series, as and when the same shall become due and payable, and such default continues for a period of 90 days; provided, however, that a valid extension of an interest payment period by the Company in accordance with the terms of
any indenture supplemental hereto shall not constitute a default in the payment of interest for this purpose; 

  
 15 

 (b) the Company defaults in the payment of the principal of (or premium, if any, on) any of the
Securities of that series as and when the same shall become due and payable whether at maturity, upon redemption, by declaration or otherwise, or in any payment required by any sinking or analogous fund established with respect to that series;
provided, however, that a valid extension of the maturity of such Securities in accordance with the terms of any indenture supplemental hereto shall not constitute a default in the payment of principal or premium, if any; 

(c) the Company fails to observe or perform any other of its covenants or agreements with respect to that series contained in this Indenture
or otherwise established with respect to that series of Securities pursuant to Section 2.01 hereof (other than a covenant or agreement that has been expressly included in this Indenture solely for the benefit of one or more series of Securities
other than such series) for a period of 90 days after the date on which written notice of such failure, requiring the same to be remedied and stating that such notice is a “Notice of Default” hereunder, shall have been given to the Company
by the Trustee, by registered or certified mail, or to the Company and the Trustee by the holders of at least 25% in principal amount of the Securities of that series at the time Outstanding; 

(d) the Company pursuant to or within the meaning of any Bankruptcy Law (i) commences a voluntary case, (ii) consents to the entry
of an order for relief against it in an involuntary case, (iii) consents to the appointment of a Custodian of it or for all or substantially all of its property or (iv) makes a general assignment for the benefit of its creditors; or 

(e) a court of competent jurisdiction enters an order under any Bankruptcy Law that (i) is for relief against the Company in an
involuntary case, (ii) appoints a Custodian of the Company for all or substantially all of its property or (iii) orders the liquidation of the Company, and the order or decree remains unstayed and in effect for 90 days. 

(2) In each and every such case (other than an Event of Default specified in clause (4) or clause (5) above), unless the principal of
all the Securities of that series shall have already become due and payable, either the Trustee or the holders of not less than 25% in aggregate principal amount of the Securities of that series then Outstanding hereunder, by notice in writing to
the Company (and to the Trustee if given by such Securityholders), may declare the principal of (and premium, if any, on) and accrued and unpaid interest on all the Securities of that series to be due and payable immediately, and upon any such
declaration the same shall become and shall be immediately due and payable. If an Event of Default specified in clause (4) or clause (5) above occurs, the principal of and accrued and unpaid interest on all the Securities of that
series shall automatically be immediately due and payable without any declaration or other act on the part of the Trustee or the holders of the Securities. 

(3) At any time after the principal of (and premium, if any, on) and accrued and unpaid interest on the Securities of that series shall have
been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the holders of a majority in aggregate principal amount of the Securities of that
series then Outstanding hereunder, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: (i) the Company has paid or deposited with the Trustee a sum sufficient to pay all matured
installments of interest upon all the Securities of that series and the principal of (and premium, if any, on) any and all Securities of that series that shall have become due otherwise than by acceleration (with interest upon such principal and
premium, if any, and, to the extent that such payment is enforceable under applicable law, upon overdue installments of interest, at the rate per annum expressed in the Securities of that series to the date of such payment or deposit) and the amount
payable to the Trustee under Section 7.06, and (ii) any and all Events of Default under the Indenture with respect to such series, other than the nonpayment of principal on (and premium, if any, on) and accrued and unpaid interest on
Securities of that series that shall not have become due by their terms, shall have been remedied or waived as provided in Section 6.06. 

No such rescission and annulment shall extend to or shall affect any subsequent default or impair any right consequent thereon. 

  
 16 

 (4) In case the Trustee shall have proceeded to enforce any right with respect to Securities of
that series under this Indenture and such proceedings shall have been discontinued or abandoned because of such rescission or annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case,
subject to any determination in such proceedings, the Company and the Trustee shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Company and the Trustee shall continue as though
no such proceedings had been taken. 
 Section 6.02 Collection of Indebtedness and Suits for Enforcement by Trustee. 

(1) The Company covenants that (i) in case it shall default in the payment of any installment of interest on any of the Securities of a
series, or in any payment required by any sinking or analogous fund established with respect to that series as and when the same shall have become due and payable, and such default shall have continued for a period of 90 days, or (ii) in case
it shall default in the payment of the principal of (or premium, if any, on) any of the Securities of a series when the same shall have become due and payable, whether upon maturity of the Securities of a series or upon redemption or upon
declaration or otherwise then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the holders of the Securities of that series, the whole amount that then shall have been become due and payable on all such Securities
for principal (and premium, if any) or interest, or both, as the case may be, with interest upon the overdue principal (and premium, if any) and (to the extent that payment of such interest is enforceable under applicable law) upon overdue
installments of interest at the rate per annum expressed in the Securities of that series; and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, and the amount payable to the Trustee
under Section 7.06. 
 (2) If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as
trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree,
and may enforce any such judgment or final decree against the Company or other obligor upon the Securities of that series and collect the moneys adjudged or decreed to be payable in the manner provided by law or equity out of the property of the
Company or other obligor upon the Securities of that series, wherever situated. 
 (3) In case of any receivership, insolvency, liquidation,
bankruptcy, reorganization, readjustment, arrangement, composition or judicial proceedings affecting the Company, or its creditors or property, the Trustee shall have power to intervene in such proceedings and take any action therein that may be
permitted by the court and shall (except as may be otherwise provided by law) be entitled to file such proofs of claim and other papers and documents as may be necessary or advisable in order to have the claims of the Trustee and of the holders of
Securities of such series allowed for the entire amount due and payable by the Company under the Indenture at the date of institution of such proceedings and for any additional amount that may become due and payable by the Company after such date,
and to collect and receive any moneys or other property payable or deliverable on any such claim, and to distribute the same after the deduction of the amount payable to the Trustee under Section 7.06; and any receiver, assignee or trustee in
bankruptcy or reorganization is hereby authorized by each of the holders of Securities of such series to make such payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to such
Securityholders, to pay to the Trustee any amount due it under Section 7.06. 
 (4) All rights of action and of asserting claims under
this Indenture, or under any of the terms established with respect to Securities of that series, may be enforced by the Trustee without the possession of any of such Securities, or the production thereof at any trial or other proceeding relative
thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for payment to the Trustee of any amounts due under
Section 7.06, be for the ratable benefit of the holders of the Securities of such series. 
 In case of an Event of Default hereunder,
the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either at law or
in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in the Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law. 

  
 17 

 Nothing contained herein shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Securityholder any plan of reorganization, arrangement, adjustment or composition affecting the Securities of that series or the rights of any holder thereof or to authorize the Trustee to vote in respect of the
claim of any Securityholder in any such proceeding. 
 Section 6.03 Application of Moneys Collected. 

Any moneys collected by the Trustee pursuant to this Article with respect to a particular series of Securities shall be applied in the
following order, at the date or dates fixed by the Trustee and, in case of the distribution of such moneys on account of principal (or premium, if any) or interest, upon presentation of the Securities of that series, and notation thereon of the
payment, if only partially paid, and upon surrender thereof if fully paid: 
 FIRST: To the payment of all indebtedness of the Company to
which such series of Securities is subordinated to the extent required by Section 7.06 and any subordination terms of the series specified as contemplated by Article Fourteen; 

SECOND: To the payment of the amounts then due and unpaid upon Securities of such series for principal (and premium, if any) and interest, in
respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium, if any) and interest,
respectively; and 
 THIRD: To the payment of the remainder, if any, to the Company or any other Person lawfully entitled thereto. 

Section 6.04 Limitation on Suits. 

No holder of any Security of any series shall have any right by virtue or by availing of any provision of this Indenture or any Security to
institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, any Security or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless (i) such holder previously
shall have given to the Trustee written notice of an Event of Default and of the continuance thereof with respect to the Securities of such series specifying such Event of Default, as hereinbefore provided; (ii) the holders of not less than 25%
in aggregate principal amount of the Securities of such series then Outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; (iii) such holder or holders
shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby; (iv) the Trustee for 90 days after its receipt of such notice, request and offer of
indemnity, shall have failed to institute any such action, suit or proceeding and (v) during such 90 day period, the holders of a majority in principal amount of the Securities of that series do not give the Trustee a direction inconsistent
with the request. 
 Notwithstanding anything contained herein to the contrary or any other provisions of this Indenture, the right of any
holder of any Security to receive payment of the principal of (and premium, if any) and interest on such Security, as therein provided, on or after the respective due dates expressed in such Security (or in the case of redemption, on the redemption
date), or to institute suit for the enforcement of any such payment on or after such respective dates or redemption date, shall not be impaired or affected without the consent of such holder and by accepting a Security hereunder it is expressly
understood, intended and covenanted by the taker and holder of every Security of such series with every other such taker and holder and the Trustee, that no one or more holders of Securities of such series shall have any right in any manner
whatsoever by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of the holders of any other of such Securities, or to obtain or seek to obtain priority over or preference to any other such holder, or
to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all holders of Securities of such series. For the protection and enforcement of the provisions of this Section,
each and every Securityholder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 

Section 6.05 Rights and Remedies Cumulative; Delay or Omission Not Waiver. 

(1) Except as otherwise provided in Section 2.07, all powers and remedies given by this Article to the Trustee or to the
Securityholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any other powers and remedies available to the Trustee or the holders of the Securities, by judicial proceedings or otherwise, to enforce the
performance or observance of the covenants and agreements contained in this Indenture or otherwise established with respect to such Securities. 

  
 18 

 (2) No delay or omission of the Trustee or of any holder of any of the Securities to exercise any
right or power accruing upon any Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or an acquiescence therein; and, subject to the provisions of
Section 6.04, every power and remedy given by this Article or by law to the Trustee or the Securityholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Securityholders. 

Section 6.06 Control by Securityholders. 

The holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding, determined in accordance with
Section 8.04, shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee with respect to such series; provided,
however, that such direction shall not be in conflict with any rule of law or with this Indenture or subject the Trustee in its sole discretion to personal liability. Subject to the provisions of Section 7.01, the Trustee shall have
the right to decline to follow any such direction if the Trustee in good faith shall, by a Responsible Officer or officers of the Trustee, determine that the proceeding so directed, subject to the Trustee’s duties under the Trust Indenture Act,
would involve the Trustee in personal liability or might be unduly prejudicial to the Securityholders not involved in the proceeding. The holders of a majority in aggregate principal amount of the Securities of any series at the time
Outstanding affected thereby, determined in accordance with Section 8.04, may on behalf of the holders of all of the Securities of such series waive any past default in the performance of any of the covenants contained herein or established
pursuant to Section 2.01 with respect to such series and its consequences, except a default in the payment of the principal of, or premium, if any, or interest on, any of the Securities of that series as and when the same shall become due by
the terms of such Securities otherwise than by acceleration (unless such default has been cured and a sum sufficient to pay all matured installments of interest and principal and any premium has been deposited with the Trustee (in accordance with
Section 6.01(3)). Upon any such waiver, the default covered thereby shall be deemed to be cured for all purposes of this Indenture and the Company, the Trustee and the holders of the Securities of such series shall be restored to
their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 

Section 6.07 Undertaking to Pay Costs. 

All parties to this Indenture agree, and each holder of any Securities by such holder’s acceptance thereof shall be deemed to have agreed,
that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good
faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Securityholder, or group of Securityholders, holding more than
10% in aggregate principal amount of the Outstanding Securities of any series, or to any suit instituted by any Securityholder for the enforcement of the payment of the principal of (or premium, if any) or interest on any Security of such series, on
or after the respective due dates expressed in such Security or established pursuant to this Indenture. 
 ARTICLE 7

of Default with respect to the Securities of that series that may have occurred, shall undertake to perform with respect to the Securities of such series such duties and only such duties as 

  
 19 

 
are specifically set forth in this Indenture, and no implied covenants shall be read into this Indenture against the Trustee. In case an Event of Default with respect to the Securities of a
series has occurred (that has not been cured or waived), the Trustee shall exercise with respect to Securities of that series such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise,
as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. 
 (2) No provision of this Indenture shall
be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 

(a) prior to the occurrence of an Event of Default with respect to the Securities of a series and after the curing or waiving of all such
Events of Default with respect to that series that may have occurred: 
 (A) the duties and obligations of the Trustee shall with respect to
the Securities of such series be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable with respect to the Securities of such series except for the performance of such duties and obligations as are
specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

(B) in the absence of bad faith on the part of the Trustee, the Trustee may with respect to the Securities of such series conclusively rely,
as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or
opinions that by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture; 

(b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Responsible Officers of the
Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; 
 (c) the Trustee shall not be
liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the holders of not less than a majority in principal amount of the Securities of any series at the time Outstanding relating to
the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Indenture with respect to the Securities of that series; and 

(d) none of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise of any of its rights or powers if there is reasonable ground for believing that the repayment of such funds or liability is not reasonably assured to it under the terms
of this Indenture or adequate indemnity against such risk is not reasonably assured to it. 
 Section 7.02 Certain Rights of
Trustee. 
 Except as otherwise provided in Section 7.01: 

(1) The Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, security or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; 

(2) Any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by a Board Resolution or an
instrument signed in the name of the Company by any authorized officer of the Company (unless other evidence in respect thereof is specifically prescribed herein); 

  
 20 

 (3) The Trustee may consult with counsel and the written advice of such counsel or, if requested,
any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or suffered or omitted hereunder in good faith and in reliance thereon; 

(4) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or
direction of any of the Securityholders pursuant to the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities that may be incurred
therein or thereby; nothing contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of an Event of Default with respect to a series of the Securities (that has not been cured or waived), to exercise with respect
to Securities of that series such of the rights and powers vested in it by this Indenture, and to use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own
affairs; 
 (5) The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith and believed by it to be
authorized or within the discretion or rights or powers conferred upon it by this Indenture; 
 (6) The Trustee shall not be bound to make
any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, security, or other papers or documents, unless requested in writing so to do
by the holders of not less than a majority in principal amount of the Outstanding Securities of the particular series affected thereby (determined as provided in Section 8.04); provided, however, that if the payment within a reasonable time to
the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture,
the Trustee may require reasonable indemnity against such costs, expenses or liabilities as a condition to so proceeding. The reasonable expense of every such examination shall be paid by the Company or, if paid by the Trustee, shall be repaid
by the Company upon demand; 
 (7) The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either
directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; 

(8) In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out
of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and
interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to
resume performance as soon as practicable under the circumstances; 
 (9) In no event shall the Trustee be responsible or liable for special,
indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action;
and 
 (10) The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail,
facsimile transmission or other similar unsecured electronic methods; provided, however, that (a) the party providing such written instructions, subsequent to such transmission of written instructions, shall provide the originally executed
instructions or directions to the Trustee in a timely manner, and (b) such originally executed instructions or directions shall be signed by an authorized representative of the party providing such instructions or directions. If the party
elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s understanding of such instructions shall be
deemed controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions notwithstanding such instructions conflict or are
inconsistent with a subsequent written instruction. The party providing electronic instructions agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including without
limitation the risk of the Trustee acting on unauthorized instructions, and the risk or interception and misuse by third parties. 

  
 21 

 In addition, the Trustee shall not be deemed to have knowledge of any Default or Event of Default
until the Trustee shall have received written notification in the manner set forth in this Indenture or a Responsible Officer of the Trustee shall have obtained actual knowledge. 

Section 7.03 Trustee Not Responsible for Recitals or Issuance or Securities. 

(1) The recitals contained herein and in the Securities shall be taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same. 
 (2) The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities. 
 (3) The Trustee shall not be accountable for the use or application by the Company of any of the
Securities or of the proceeds of such Securities, or for the use or application of any moneys paid over by the Trustee in accordance with any provision of this Indenture or established pursuant to Section 2.01, or for the use or application of
any moneys received by any paying agent other than the Trustee. 
 Section 7.04 May Hold Securities. 

The Trustee or any paying agent or Security Registrar, in its individual or any other capacity, may become the owner or pledgee of Securities
with the same rights it would have if it were not Trustee, paying agent or Security Registrar.

 Subject to the provisions of Section 11.05, all moneys received by the Trustee shall, until used or applied as herein provided,
be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any moneys received by it hereunder except
such as it may agree with the Company to pay thereon. 
 Section 7.06 Compensation and Reimbursement. 

(1) The Company covenants and agrees to pay to the Trustee, and the Trustee shall be entitled to, such reasonable compensation (which shall not
be limited by any provision of law in regard to the compensation of a trustee of an express trust) as the Company and the Trustee may from time to time agree in writing, for all services rendered by it in the execution of the trusts hereby created
and in the exercise and performance of any of the powers and duties hereunder of the Trustee, and, except as otherwise expressly provided herein, the Company will pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all Persons not regularly in its
employ), except any such expense, disbursement or advance as may arise from its negligence or bad faith and except as the Company and Trustee may from time to time agree in writing. The Company also covenants to indemnify the Trustee (and its
officers, agents, directors and employees) for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on the part of the Trustee and arising out of or in connection with the acceptance or
administration of this trust, including the reasonable costs and expenses of defending itself against any claim of liability in the premises. 

(2) The obligations of the Company under this Section to compensate and indemnify the Trustee and to pay or reimburse the Trustee for
reasonable expenses, disbursements and advances shall constitute indebtedness of the Company to which the Securities are subordinated. Such additional indebtedness shall be secured by a lien prior to that of the Securities upon all property and
funds held or collected by the Trustee as such, except funds held in trust for the benefit of the holders of particular Securities. 

  
 22 

 (3) To ensure the Company’s payment obligations in this Section, the Trustee shall have a
lien prior to the Securities on all funds or property held or collected by the Trustee, except that held in trust to pay principal of or interest on particular Securities. When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 6.01(1)(d) or (1)(e), the expenses (including the reasonable fees and expenses of its counsel) and the compensation for services in connection therewith are to constitute expenses of administration
under any bankruptcy law. The provisions of this Section 7.06 shall survive the termination of this Indenture and the resignation or removal of the Trustee. 

Section 7.07 Reliance on Officer’s Certificate. 

Except as otherwise provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it
reasonably necessary or desirable that a matter be proved or established prior to taking or suffering or omitting to take any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the
absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officer’s Certificate delivered to the Trustee and such certificate, in the absence of negligence or bad faith on the part
of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted to be taken by it under the provisions of this Indenture upon the faith thereof. 

Section 7.08 Disqualification; Conflicting Interests. 

If the Trustee has or shall acquire any “conflicting interest” within the meaning of Section 310(b) of the Trust Indenture
Act, the Trustee and the Company shall in all respects comply with the provisions of Section 310(b) of the Trust Indenture Act. 

Section 7.09 Corporate Trustee Required; Eligibility. 

There shall at all times be a Trustee with respect to the Securities issued hereunder which shall at all times be a corporation organized and
doing business under the laws of the United States of America or any state or territory thereof or of the District of Columbia, or a corporation or other Person permitted to act as trustee by the Commission, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least fifty million U.S. dollars ($50,000,000), and subject to supervision or examination by federal, state, territorial, or District of Columbia authority. 

If such corporation or other Person publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation or other Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of
condition so published. The Company may not, nor may any Person directly or indirectly controlling, controlled by, or under common control with the Company, serve as Trustee. In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, the Trustee shall resign immediately in the manner and with the effect specified in Section 7.10. 

Section 7.10 Resignation and Removal; Appointment of Successor. 

(1) The Trustee or any successor hereafter appointed may at any time resign with respect to the Securities of one or more series by giving
written notice thereof to the Company and by transmitting notice of resignation by mail, first class postage prepaid, to the Securityholders of such series, as their names and addresses appear upon the Security Register. Upon receiving such
notice of resignation, the Company shall promptly appoint a successor trustee with respect to Securities of such series by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered
to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 30 days after the mailing of such notice of resignation, the resigning Trustee may
petition any court of competent jurisdiction for the appointment of a successor trustee with respect to Securities of such series, or any Securityholder of that series who has been a bona fide holder of a Security or Securities for at least six
months may on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon after such notice, if any, as it may deem proper and prescribe, appoint a successor
trustee. 
 (2) In case at any time any one of the following shall occur: 

  
 23 

 (a) the Trustee shall fail to comply with the provisions of Section 7.08 after written
request therefor by the Company or by any Securityholder who has been a bona fide holder of a Security or Securities for at least six months; or 

(b) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.09 and shall fail to resign after written
request therefor by the Company or by any such Securityholder; or 
 (c) the Trustee shall become incapable of acting, or shall be adjudged
a bankrupt or insolvent, or commence a voluntary bankruptcy proceeding, or a receiver of the Trustee or of its property shall be appointed or consented to, or any public officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation; 
 then, in any such case, the Company may remove the Trustee with
respect to all Securities and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor
trustee, or any Securityholder who has been a bona fide holder of a Security or Securities for at least six months may, on behalf of that holder and all others similarly situated, petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor trustee. Such court may thereupon after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 

(3) The holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding may at any time remove the
Trustee with respect to such series by so notifying the Trustee and the Company and may appoint a successor Trustee for such series with the consent of the Company. 

(4) Any resignation or removal of the Trustee and appointment of a successor trustee with respect to the Securities of a series pursuant to any
of the provisions of this Section shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.11. 

(5) Any successor trustee appointed pursuant to this Section may be appointed with respect to the Securities of one or more series or all
of such series, and at any time there shall be only one Trustee with respect to the Securities of any particular series. 

Section 7.11 Acceptance of Appointment By Successor. 

(1) In case of the appointment hereunder of a successor trustee with respect to all Securities, every such successor trustee so appointed 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 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. 
 (2) In case of the appointment hereunder of a successor trustee with respect to the Securities of one or more (but not
all) series, the Company, the retiring Trustee and each successor trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor trustee shall accept such appointment
and which (i) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities
of that or those series to which the appointment of such successor trustee relates, (ii) shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee
with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (iii) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust, that
each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee and that no 

  
 24 

 
Trustee shall be responsible for any act or failure to act on the part of any other Trustee hereunder; and upon the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided therein, such retiring Trustee shall with respect to the Securities of that or those series to which the appointment of such successor trustee relates have no further
responsibility for the exercise of rights and powers or for the performance of the duties and obligations vested in the Trustee under this Indenture, and each 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 with respect to the Securities of that or those series to which the appointment of such successor trustee relates; but, on request of the Company or any successor trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor trustee, to the extent contemplated by such supplemental indenture, the property and money held by such retiring Trustee hereunder with respect to the Securities of that or
those series to which the appointment of such successor trustee relates. 
 (3) Upon request of any such successor trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and confirming to such successor trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be. 

(4) No successor trustee shall accept its appointment unless at the time of such acceptance such successor trustee shall be qualified and
eligible under this Article. 
 (5) Upon acceptance of appointment by a successor trustee as provided in this Section, the Company shall
transmit notice of the succession of such trustee hereunder by mail, first class postage prepaid, to the Securityholders, as their names and addresses appear upon the Security Register. If the Company fails to transmit such notice within ten
days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be transmitted at the expense of the Company. 

Section 7.12 Merger, Conversion, Consolidation or Succession to Business. 

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to the corporate trust business of the Trustee, including the administration of the trust created by this Indenture, shall be the successor of
the Trustee hereunder, provided that such corporation shall be qualified under the provisions of Section 7.08 and eligible under the provisions of Section 7.09, without the execution or filing of any paper or any further act on the part of
any of the parties hereto, anything herein to the contrary notwithstanding. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. 

Section 7.13 Preferential Collection of Claims Against the Company. 

The Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship described in
Section 311(b) of the Trust Indenture Act. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent included therein. 

Section 7.14 Notice of Default 

If any Event of Default occurs and is continuing and if such Event of Default is known to a Responsible Officer of the Trustee, the Trustee
shall mail to each Securityholder in the manner and to the extent provided in Section 313(c) of the Trust Indenture Act notice of the Event of Default within the earlier of 90 days after it occurs and 30 days after it is known to a
Responsible Officer of the Trustee or written notice of it is received by the Trustee, unless such Event of Default has been cured; provided, however, that, except in the case of a default in the payment of the principal of (or premium, if
any) or interest on any Security, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith
determine that the withholding of such notice is in the interest of the Securityholders. 

  
 25 

 ARTICLE 8 

CONCERNING THE SECURITYHOLDERS 

Section 8.01 Evidence of Action by Securityholders. 

Whenever in this Indenture it is provided that the holders of a majority or specified percentage in aggregate principal amount of the
Securities of a particular series may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action the holders of
such majority or specified percentage of that series have joined therein may be evidenced by any instrument or any number of instruments of similar tenor executed by such holders of Securities of that series in person or by agent or proxy appointed
in writing. 
 If the Company shall solicit from the Securityholders of any series any request, demand, authorization, direction, notice,
consent, waiver or other action, the Company may, at its option, as evidenced by an Officer’s Certificate, fix in advance a record date for such series for the determination of Securityholders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other action, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other action may be
given before or after the record date, but only the Securityholders of record at the close of business on the record date shall be deemed to be Securityholders for the purposes of determining whether Securityholders of the requisite proportion of
Outstanding Securities of that series have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other action, and for that purpose the Outstanding Securities of that series shall be computed
as of the record date; provided, however, that no such authorization, agreement or consent by such Securityholders on the record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later
than six months after the record date. 
 Section 8.02 Proof of Execution by Securityholders. 

Subject to the provisions of Section 7.01, proof of the execution of any instrument by a Securityholder (such proof will not require
notarization) or his agent or proxy and proof of the holding by any Person of any of the Securities shall be sufficient if made in the following manner: 

(1) The fact and date of the execution by any such Person of any instrument may be proved in any reasonable manner acceptable
to the Trustee. 
 (2) The ownership of Securities shall be proved by the Security Register of such Securities or by a
certificate of the Security Registrar thereof. 
 The Trustee may require such additional proof of any matter referred to in this Section as it shall
deem necessary. 
 Section 8.03 Who May be Deemed Owners. 

Prior to the due presentment for registration of transfer of any Security, the Company, the Trustee, any paying agent and any Security
Registrar may deem and treat the Person in whose name such Security shall be registered upon the books of the Company as the absolute owner of such Security (whether or not such Security shall be overdue and notwithstanding any notice of ownership
or writing thereon made by anyone other than the Security Registrar) for the purpose of receiving payment of or on account of the principal of, premium, if any, and (subject to Section 2.03) interest on such Security and for all other purposes;
and neither the Company nor the Trustee nor any paying agent nor any Security Registrar shall be affected by any notice to the contrary. 

Section 8.04 Certain Securities Owned by Company Disregarded. 

In determining whether the holders of the requisite aggregate principal amount of Securities of a particular series have concurred in any
direction, consent or waiver under this Indenture, the Securities of that series that are owned by the Company or any other obligor on the Securities of that series or by any Person directly or indirectly controlling or controlled by or under common
control with the Company or any other obligor on the Securities of that series shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except 

  
 26 

 
that for the purpose of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver, only Securities of such series that the Trustee actually knows are
so owned shall be so disregarded. The Securities so owned that have been pledged in good faith may be regarded as Outstanding for the purposes of this Section, if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s
right so to act with respect to such Securities and that the pledgee is not a Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any such other obligor. In case of a dispute
as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. 

Section 8.05 Actions Binding on Future Securityholders. 

At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the
holders of the majority or percentage in aggregate principal amount of the Securities of a particular series specified in this Indenture in connection with such action, any holder of a Security of that series that is shown by the evidence to be
included in the Securities the holders of which have consented to such action may, by filing written notice with the Trustee, and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such
Security. Except as aforesaid any such action taken by the holder of any Security shall be conclusive and binding upon such holder and upon all future holders and owners of such Security, and of any Security issued in exchange therefor, on
registration of transfer thereof or in place thereof, irrespective of whether or not any notation in regard thereto is made upon such Security. Any action taken by the holders of the majority or percentage in aggregate principal amount of the
Securities of a particular series specified in this Indenture in connection with such action shall be conclusively binding upon the Company, the Trustee and the holders of all the Securities of that series. 

ARTICLE 9 
 SUPPLEMENTAL
INDENTURES 
 Section 9.01 Supplemental Indentures Without the Consent of Securityholders. 

In addition to any supplemental indenture otherwise authorized by this Indenture, the Company and the Trustee may from time to time and at any
time enter into an indenture or indentures supplemental hereto (which shall conform to the provisions of the Trust Indenture Act as then in effect), without the consent of the Securityholders, for one or more of the following purposes: 

(1) to cure any ambiguity, defect, or inconsistency herein or in the Securities of any series; 

(2) to comply with Article Ten; 

(3) to provide for uncertificated Securities in addition to or in place of certificated Securities; 

(4) to add to the covenants, restrictions, conditions or provisions relating to the Company for the benefit of the holders of all or any series
of Securities (and if such covenants, restrictions, conditions or provisions are to be for the benefit of less than all series of Securities, stating that such covenants, restrictions, conditions or provisions are expressly being included solely for
the benefit of such series), to make the occurrence, or the occurrence and the continuance, of a default in any such additional covenants, restrictions, conditions or provisions an Event of Default, or to surrender any right or power herein
conferred upon the Company; 
 (5) to add to, delete from, or revise the conditions, limitations, and restrictions on the authorized amount,
terms, or purposes of issue, authentication, and delivery of Securities, as herein set forth; 
 (6) to make any change that does not
adversely affect the rights of any Securityholder in any material respect; 
 (7) to provide for the issuance of and establish the form and
terms and conditions of the Securities of any series as provided in Section 2.01, to establish the form of any certifications required to be furnished pursuant to the terms of this Indenture or any series of Securities, or to add to the rights
of the holders of any series of Securities; 

  
 27 

 (8) to evidence and provide for the acceptance of appointment hereunder by a successor trustee;
or 
 (9) to comply with any requirements of the Commission or any successor in connection with the qualification of this Indenture under the
Trust Indenture Act. 
 The Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, and
to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into any such supplemental indenture that affects the Trustee’s own rights, duties or immunities
under this Indenture or otherwise. 
 Any supplemental indenture authorized by the provisions of this Section may be executed by the
Company and the Trustee without the consent of the holders of any of the Securities at the time Outstanding, notwithstanding any of the provisions of Section 9.02. 

Section 9.02 Supplemental Indentures With Consent of Securityholders. 

With the consent (evidenced as provided in Section 8.01) of the holders of not less than a majority in aggregate principal amount of the
Securities of each series affected by such supplemental indenture or indentures at the time Outstanding, the Company, when authorized by a Board Resolution, and the Trustee may from time to time and at any time enter into an indenture or indentures
supplemental hereto (which shall conform to the provisions of the Trust Indenture Act as then in effect) for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any
supplemental indenture or of modifying in any manner not covered by Section 9.01 the rights of the holders of the Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall, without the consent
of the holders of each Security then Outstanding and affected thereby, (a) extend the fixed maturity of any Securities of any series, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon,
or reduce any premium payable upon the redemption thereof or (b) reduce the aforesaid percentage of Securities, the holders of which are required to consent to any such supplemental indenture. 

It shall not be necessary for the consent of the Securityholders of any series affected thereby under this Section to approve the
particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. 

Section 9.03 Effect of Supplemental Indentures. 

Upon the execution of any supplemental indenture pursuant to the provisions of this Article or of Section 10.01, this Indenture
shall, with respect to such series, be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the
holders of Securities of the series affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental indenture
shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 
 Section 9.04 Securities
Affected by Supplemental Indentures. 
 Securities of any series affected by a supplemental indenture, authenticated and delivered after
the execution of such supplemental indenture pursuant to the provisions of this Article or of Section 10.01, may bear a notation in form approved by the Company, provided such form meets the requirements of any securities exchange upon
which such series may be listed, as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities of that series so modified as to conform, in the opinion of the Board of Directors, to any
modification of this Indenture contained in any such supplemental indenture may be prepared by the Company, authenticated by the Trustee and delivered in exchange for the Securities of that series then Outstanding. 

Section 9.05 Execution of Supplemental Indentures. 

Upon the request of the Company, accompanied by its Board Resolutions authorizing the execution of any such supplemental indenture, and upon
the filing with the Trustee of evidence of the consent of Securityholders 

  
 28 

 
required to consent thereto as aforesaid, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own
rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion but shall not be obligated to enter into such supplemental indenture. The Trustee, subject to the provisions of Section 7.01, shall
receive an Officer’s Certificate or an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant to this Article is authorized or permitted by the terms of this Article and that all conditions
precedent to the execution of the supplemental indenture have been complied with; provided, however, that such Officer’s Certificate or Opinion of Counsel need not be provided in connection with the execution of a supplemental indenture that
establishes the terms of a series of Securities pursuant to Section 2.01 hereof. 
 Promptly after the execution by the Company and the
Trustee of any supplemental indenture pursuant to the provisions of this Section, the Company shall (or shall direct the Trustee to) transmit by mail, first class postage prepaid, a notice, setting forth in general terms the substance of such
supplemental indenture, to the Securityholders of all series affected thereby as their names and addresses appear upon the Security Register. Any failure of the Company to mail, or cause the mailing of, such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental indenture. 
 ARTICLE 10 

SUCCESSOR ENTITY 

Section 10.01 Company May Consolidate, Etc. 

Nothing contained in this Indenture shall prevent any consolidation or merger of the Company with or into any other Person (whether or not
affiliated with the Company) or successive consolidations or mergers in which the Company or its successor or successors shall be a party or parties, or shall prevent any sale, conveyance, transfer or other disposition of the property of the Company
or its successor or successors as an entirety, or substantially as an entirety, to any other corporation (whether or not affiliated with the Company or its successor or successors) authorized to acquire and operate the same; provided, however,
(a) the Company hereby covenants and agrees that, upon any such consolidation or merger (in each case, if the Company is not the survivor of such transaction), sale, conveyance, transfer or other disposition, the due and punctual payment of the
principal of (premium, if any) and interest on all of the Securities of all series in accordance with the terms of each series, according to their tenor, and the due and punctual performance and observance of all the covenants and conditions of this
Indenture with respect to each series or established with respect to such series pursuant to Section 2.01 to be kept or performed by the Company shall be expressly assumed, by supplemental indenture (which shall conform to the provisions of the
Trust Indenture Act, as then in effect) reasonably satisfactory in form to the Trustee executed and delivered to the Trustee by the entity formed by such consolidation, or into which the Company shall have been merged, or by the entity which shall
have acquired such property and (b) in the event that the Securities of any series then Outstanding are convertible into or exchangeable for shares of common stock or other securities of the Company, such entity shall, by such supplemental
indenture, make provision so that the Securityholders of Securities of that series shall thereafter be entitled to receive upon conversion or exchange of such Securities the number of securities or property to which a holder of the number of shares
of common stock or other securities of the Company deliverable upon conversion or exchange of those Securities would have been entitled had such conversion or exchange occurred immediately prior to such consolidation, merger, sale, conveyance,
transfer or other disposition. 
 Section 10.02 Successor Entity Substituted. 

(1) In case of any such consolidation, merger, sale, conveyance, transfer or other disposition and upon the assumption by the successor entity
by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the obligations set forth under Section 10.01 on all of the Securities of all series Outstanding, such successor entity shall succeed
to and be substituted for the Company with the same effect as if it had been named as the Company herein, and thereupon the predecessor corporation shall be relieved of all obligations and covenants under this Indenture and the Securities. 

(2) In case of any such consolidation, merger, sale, conveyance, transfer or other disposition, such changes in phraseology and form (but not
in substance) may be made in the Securities thereafter to be issued as may be appropriate. 

  
 29 

 (3) Nothing contained in this Article shall require any action by the Company in the case of
a consolidation or merger of any Person into the Company where the Company is the survivor of such transaction, or the acquisition by the Company, by purchase or otherwise, of all or any part of the property of any other Person (whether or not
affiliated with the Company).

SATISFACTION AND DISCHARGE 

Section 11.01 Satisfaction and Discharge of Indenture. 

If at any time: (a) the Company shall have delivered to the Trustee for cancellation all Securities of a series theretofore authenticated
and not delivered to the Trustee for cancellation (other than any Securities that shall have been destroyed, lost or stolen and that shall have been replaced or paid as provided in Section 2.07 and Securities for whose payment money or
Governmental Obligations have theretofore been deposited in trust or segregated and held in trust by the Company and thereupon repaid to the Company or discharged from such trust, as provided in Section 11.05); or (b) all such Securities
of a particular series not theretofore delivered to the Trustee for cancellation shall have become due and payable, or are by their terms to become due and payable within one year or are to be called for redemption within one year under arrangements
satisfactory to the Trustee for the giving of notice of redemption, and the Company shall deposit or cause to be deposited with the Trustee as trust funds the entire amount in moneys or Governmental Obligations or a combination thereof, sufficient
in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay at maturity or upon redemption all Securities of that series not theretofore delivered to
the Trustee for cancellation, including principal (and premium, if any) and interest due or to become due to such date of maturity or date fixed for redemption, as the case may be, and if the Company shall also pay or cause to be paid all other sums
payable hereunder with respect to such series by the Company then this Indenture shall thereupon cease to be of further effect with respect to such series except for the provisions of Sections 2.03, 2.05, 2.07, 4.01, 4.02, 4.03 and 7.10, that shall
survive until the date of maturity or redemption date, as the case may be, and Sections 7.06 and 11.05, that shall survive to such date and thereafter, and the Trustee, on demand of the Company and at the cost and expense of the Company shall
execute proper instruments acknowledging satisfaction of and discharging this Indenture with respect to such series.

Securities of that series not theretofore delivered to the Trustee for cancellation, including principal (and premium, if any) and interest due or to become due to such date of maturity or date fixed for redemption, as the case may be, and if the
Company shall also pay or cause to be paid all other sums payable hereunder by the Company with respect to such series, then after the date such moneys or Governmental Obligations, as the case may be, are deposited with the Trustee the obligations

to be given, made or served by the Trustee or by the holders of Securities or by any other Person pursuant to this Indenture to or on the Company may be given or served by being deposited in first class mail, postage prepaid, addressed (until

shall be construed in accordance with the laws of said State, except to the extent that the Trust Indenture Act is applicable. 

Section 13.06 Treatment of Securities as Debt. 

It is intended that the Securities will be treated as indebtedness and not as equity for federal income tax purposes. The provisions of

Precedent. 
 (1) Upon any application or demand by the Company to the Trustee to take any action under any of the provisions of this

(and premium, if any) may be made on the next succeeding Business Day with the same force and effect as if made on the nominal date of maturity or redemption, and no interest shall accrue for the period after such nominal date. 

  
 32 

 Section 13.09 Conflict with Trust Indenture Act. 

If and to the extent that any provision of this Indenture limits, qualifies or conflicts with the duties imposed by Sections 310 to 317,
inclusive, of the Trust Indenture Act, such imposed duties shall control. 
 Section 13.10 Counterparts. 

This Indenture may be executed in any number of counterparts, each of which shall be an original, but such counterparts shall together
constitute but one and the same instrument.

In case any one or more of the provisions contained in this Indenture or in the Securities of any series shall for any reason be held to be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Indenture or of such Securities, but this Indenture and such Securities shall be construed as if
such invalid or illegal or unenforceable provision had never been contained herein or therein. 
 Section 13.12 Compliance
Certificates. 
 The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year during which any Securities
of any series were outstanding, an officer’s certificate stating whether or not the signers know of any Event of Default that occurred during such fiscal year. Such certificate shall contain a certification from the principal executive
officer, principal financial officer or principal accounting officer of the Company that a review has been conducted of the activities of the Company and the Company’s performance under this Indenture and that the Company has complied with all
conditions and covenants under this Indenture. For purposes of this Section 13.12, such compliance shall be determined without regard to any period of grace or requirement of notice provided under this Indenture. If the officer of the
Company signing such certificate has knowledge of such an Event of Default, the certificate shall describe any such Event of Default and its status.

context otherwise requires, any reference to interest on, or in respect of, any Security in this Indenture shall be deemed to include Additional Interest if, in such context, Additional Interest is, was or would be payable. Unless the context
otherwise requires, any express mention of Additional Interest in any provision hereof shall not be construed as excluding Additional Interest, as the case may be, in those provisions hereof where such express mention is not made. 

ARTICLE 2 
 THE
SECURITIES 
 Section 2.01. Form and Dating. The Securities and the Trustee’s certificate of authentication
shall be substantially in the form set forth in Exhibit A, which is incorporated in and forms a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage; provided
that such notations, legends or endorsements are in a form acceptable to the Company. Each Security shall be dated the date of its authentication. 

So long as the Securities, or portion thereof, are eligible for book-entry settlement with the Depository, unless otherwise required by law,
subject to Section 2.15, such Securities may be represented by one or more Securities in global form registered in the name of the Depository or the nominee of the Depository (“Global Securities”). The transfer and exchange of
beneficial interests in any such Global Securities shall be effected through the Depository in accordance with this Indenture and the Applicable Procedures. Except as provided in Section 2.15, beneficial owners of a Global Security shall not be
entitled to have certificates registered in their names, will not receive or be entitled to receive Physical Securities and will not be considered Holders of such Global Security. 

Any Global Securities shall represent such of the outstanding principal amount of Securities as shall be specified therein and shall provide
that it shall represent the aggregate principal amount of outstanding Securities from time to time endorsed thereon and that the aggregate principal amount of outstanding Securities represented thereby may from time to time be increased or reduced
to reflect issuances, repurchases, redemptions, conversions, cancellations, transfers or exchanges permitted hereby. Any endorsement of a Global Security to reflect the amount of any increase or decrease in the amount of outstanding Securities
represented thereby shall be made by the Trustee or the custodian for the Global Security, at the written direction of 

  
 12 

 
the Trustee, in such manner and upon instructions given by the Holder of such Securities in accordance with this Indenture. Payment of principal of, and interest on, any Global Securities
(including the Fundamental Change Repurchase Price or Redemption Price, if applicable) shall be made to the Depository in immediately available funds. 

Section 2.02. Execution and Authentication. One duly authorized Officer shall sign the Securities for the Company by manual
or facsimile signature. 
 A Security’s validity shall not be affected by the failure of an Officer whose signature is on such Security
to hold, at the time the Security is authenticated, the same office at the Company. 
 A Security shall not be valid until duly
authenticated by the manual signature of the Trustee. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. 

Upon a Company Order, the Trustee shall authenticate Securities for original issue in the aggregate principal amount of $250,000,000. The
aggregate principal amount of Securities outstanding at any time may not exceed $250,000,000, subject to the immediately succeeding paragraph and except for Securities authenticated and delivered in lieu of lost, destroyed or wrongfully taken
Securities pursuant to Section 2.07. 
 The Company may not, without the consent of Holders of 100% in aggregate principal amount of
the outstanding Securities, increase the aggregate principal amount of Securities by issuing additional Securities in the future (except for Securities authenticated and delivered upon registration of transfer or exchange for or in lieu of other
Securities pursuant to Sections 2.06, 2.07, 2.10, 2.15, 2.16, 2.17, 3.01(h) and 10.02(f)). 
 Upon a Company Order, the Trustee shall
authenticate Securities, including Securities not bearing the Security Private Placement Legend, to be issued to the transferees when sold pursuant to an effective registration statement under the Securities Act as set forth in Section 2.16(b),
when sold pursuant to Rule 144 under the Securities Act or when not otherwise required under this Indenture to bear the Security Private Placement Legend. 

The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such authenticating agent. An
authenticating agent so appointed has the same rights as a Securities Agent to deal with the Company and its Affiliates. 
 If a Company
Order pursuant to this Section 2.02 has been, or simultaneously is, delivered, then any instructions by the Company to the Trustee with respect to endorsement, delivery or redelivery of a Security that is a Global Security shall be in writing. The
Securities shall be issuable only in registered form without interest coupons and only in minimum denominations of $1,000 principal amount and any integral multiple thereof. 

  
 13 

 Section 2.03. Registrar, Paying Agent and Conversion Agent. The Company shall
maintain, or shall cause to be maintained, in the continental United States, (i) an office or agency where Securities may be presented for registration of transfer or for exchange (“Registrar”), (ii) an office or agency
where Securities may be presented for payment (“Paying Agent”) and (iii) an office or agency where Securities may be presented for conversion (“Conversion Agent”). The Registrar shall keep a register of the
Securities and of their transfer and exchange. The Company may appoint or change one or more co-registrars, one or more additional paying agents and one or more additional conversion agents, subject to providing written notification to the Trustee
of any such new registrar, paying agent or conversion agent, and may act in any such capacity on its own behalf. The term “Registrar” includes any co-registrar; the term “Paying Agent” includes any additional paying
agent; and the term “Conversion Agent” includes any additional conversion agent. 
 The Company shall use reasonable best
efforts to enter into an appropriate agency agreement with any Securities Agent not a party to this Indenture, if any. Such agency agreement, if any, shall implement the provisions of this Indenture that relate to such Securities Agent. The Company
shall notify the Trustee in writing of the name and address of any Securities Agent not a party to this Indenture. If the Company fails to maintain an entity other than the Trustee as Registrar, Paying Agent or Conversion Agent, the Trustee shall
act as such. 
 The Company initially appoints the Trustee as Paying Agent, Registrar and Conversion Agent. 

Section 2.04. Paying Agent to Hold Money in Trust. Each Paying Agent shall hold in trust for the benefit of the Holders or the
Trustee all moneys held by the Paying Agent for the payment of the Securities, and shall notify the Trustee in writing of any Default by the Company in making any such payment. While any such Default continues, the Trustee may require a Paying Agent
to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds so paid by it. Upon payment over to the Trustee, the Paying Agent shall have no
further liability for such money. If the Company acts as Paying Agent, it shall segregate and hold as a separate trust fund all money held by it as Paying Agent; provided that the Company may not act as Paying Agent upon the occurrence and
continuance of an Event of Default. 
 Section 2.05. Holder Lists. The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and addresses of Holders and shall otherwise comply with Section 312(a) of the TIA. If the Trustee is not the Registrar, the Company shall furnish, or shall cause to be
furnished, to the Trustee at least five Business Days before each April 1 and October 1 and at such other times as the Trustee may request in writing a list, in such form and as of such date as the Trustee may reasonably require, of the
names and addresses of Holders appearing in the security register of the Registrar and the Company shall otherwise comply with Section 312(a) of the TIA. 

Section 2.06. Transfer and Exchange. Subject to Section 2.15 and Section 2.16, where Securities are presented to
the Registrar with a request to register their transfer or to exchange them for an equal principal amount of Securities of other authorized denominations, the Registrar 

  
 14 

 
shall register the transfer or make the exchange if its requirements under this Indenture for such transaction are met. To permit registrations of transfer and exchanges, the Trustee shall
authenticate Securities at the Registrar’s request or upon the Trustee’s receipt of a Company Order therefor. The Company, the Registrar or the Trustee, as the case may be, shall not be required to register the transfer of or exchange any
Security for which a Repurchase Notice or notice of redemption pursuant to Article 11 has been delivered, and not withdrawn, in accordance with this Indenture, except if the Company has defaulted in the payment of the Fundamental Change Repurchase
Price or the Redemption Price with respect to such Security or to the extent that a portion of such Security is not subject to such Repurchase Notice or notice of redemption. 

No service charge shall be made for any transfer, exchange or conversion of Securities, but the Company and the Trustee may require payment of
a sum sufficient to cover any documentary, stamp, issue or transfer tax or similar governmental charge that may be imposed in connection with any transfer, exchange or conversion of Securities, other than exchanges pursuant to Section 2.07,
Section 2.10, Section 3.01, Section 9.04 or Section 10.02, in each case, not involving any transfer. 

Section 2.07. Replacement Securities. If the Holder of a Security claims that the Security has been mutilated, lost, destroyed or
wrongfully taken, the Company shall issue and the Trustee shall authenticate, at the Holder’s expense, a replacement Security upon surrender to the Trustee of the mutilated Security, or upon delivery to the Trustee of evidence of the loss,
destruction or theft of the Security satisfactory to the Trustee and the Company. In the case of a lost, destroyed or wrongfully taken Security, if required by the Trustee or the Company, indemnity (including in the form of a bond) must be provided
by the Holder that is reasonably satisfactory to the Trustee and the Company to indemnify and hold harmless the Company, the Trustee or any Securities Agent from any loss that any of them may suffer if such Security is replaced. 

In case any such mutilated, lost, destroyed or wrongfully taken Security has become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay the amounts due in respect of such Security as provided hereunder. 
 Every replacement Security is
an additional obligation of the Company only as provided in Section 2.08. 
 Section 2.08. Outstanding Securities.
Securities outstanding at any time are all the Securities authenticated by the Trustee except for those converted, those cancelled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding.
Except to the extent provided in Section 2.09, a Security does not cease to be outstanding because the Company or one of its Subsidiaries or Affiliates holds the Security. 

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it, or
a court holds, that the replaced Security is held by a protected purchaser. 

  
 15 

 If the Paying Agent (in the case of a Paying Agent other than the Company) holds, as of 10:00
a.m. New York City time on a Fundamental Change Repurchase Date or a Redemption Date or the Maturity Date, money sufficient to pay the aggregate Fundamental Change Repurchase Price, Redemption Price or principal amount (plus accrued and unpaid
interest, if any), as the case may be, with respect to all Securities to be repurchased or paid on such Fundamental Change Repurchase Date or Redemption Date or the Maturity Date, as the case may be, in each case, payable as herein provided on such
Fundamental Change Repurchase Date or Redemption Date or the Maturity Date, then (unless there shall be a Default in the payment of such aggregate Fundamental Change Repurchase Price, Redemption Price or principal amount, or of such accrued and
unpaid interest), except as otherwise provided herein, then on and after such date such Securities shall be deemed to be no longer outstanding, interest on such Securities shall cease to accrue, and such Securities shall be deemed to be paid whether
or not such Securities are delivered to the Paying Agent. Thereafter, all rights of the Holders of such Securities shall terminate with respect to such Securities, other than the right to receive the Fundamental Change Repurchase Price, Redemption
Price or principal amount, as the case may be, plus, if applicable, such accrued and unpaid interest in accordance with this Indenture. 

If a Security is converted in accordance with Article 10 then, from and after the time of such conversion on the Conversion Date, such
Security shall cease to be outstanding, and interest, if any, shall cease to accrue on such Security unless there shall be a Default in the payment or delivery of the consideration payable and/or deliverable hereunder upon such conversion (except
that any such Security will remain outstanding solely for the purpose of receiving any interest or other amounts due following such conversion as set forth in this Indenture). 

Section 2.09. Securities Held by the Company or an Affiliate. In determining whether the Holders of the required aggregate
principal amount of Securities have concurred in any direction, waiver or consent with respect to this Indenture or the Securities, Securities owned by the Company or any of its Subsidiaries or Affiliates (other than Atairos Management, L.P. or any
of its Affiliates) shall be considered as though not outstanding, except that, for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities that a Responsible Officer of
the Trustee actually knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be considered to be outstanding for purposes of this Section 2.09 if the pledgee establishes, to the satisfaction of
the Trustee, the pledgee’s right to so concur with respect to such Securities and that the pledgee is not, and is not acting at the direction or on behalf of, the Company, any other obligor on the Securities, an Affiliate of the Company (other
than Atairos Management, L.P. or any of its Affiliates) or an Affiliate of any such other obligor (other than Atairos Management, L.P. or any of its Affiliates). In case of a dispute as to whether the pledgee has established the foregoing, any
decision by the Trustee taken upon the advice of counsel shall provide full protection to the Trustee. The Company shall furnish to the Trustee an Officers’ Certificate listing and identifying all Securities, if any, known by the Company to be
owned or held by or for the account of any of the above described Persons; and the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Securities not
listed therein are outstanding for the purpose of any such determination. For the avoidance of doubt and notwithstanding Section 316(a)(1) of the TIA or anything herein to 

  
 16 

 
the contrary, no Atairos Securities shall be deemed to be owned by the Company or any of its Subsidiaries or Affiliates for purposes of this Indenture, the Securities and any direction, waiver or
consent with respect thereto. 
 Section 2.10. Temporary Securities. Until definitive Securities are ready for delivery, the
Company may prepare and the Trustee, upon receipt of a Company Order therefor, shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company
considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee, upon receipt of a Company Order therefor, shall authenticate definitive Securities in exchange for temporary Securities. Until so
exchanged, each temporary Security shall in all respects be entitled to the same benefits under this Indenture as definitive Securities, and such temporary Security shall be exchangeable for definitive Securities in accordance with the terms of this
Indenture. 
 Section 2.11. Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation.
The Registrar, Paying Agent and Conversion Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange, payment or conversion. The Trustee shall promptly cancel all Securities surrendered for transfer, exchange,
payment, conversion or cancellation in accordance with its customary procedures. The Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant
to Article 10. All cancelled Securities held by the Trustee shall be disposed of in accordance with its customary procedure for the disposal of cancelled securities. 

Section 2.12. Defaulted Interest. If, and to the extent, the Company defaults in a payment of interest on the Securities, the
Company shall pay in cash the defaulted interest in any lawful manner plus, to the extent not prohibited by applicable statute or case law, interest on such defaulted interest at the rate provided in the Securities. The Company may pay the defaulted
interest (plus interest on such defaulted interest) to the Persons who are Holders on a subsequent special record date. The Company shall fix such special record date and payment date. At least fifteen (15) calendar days before the special
record date, the Company shall send to Holders and the Trustee a notice that states the special record date, payment date and amount of interest to be paid. Upon the due payment in full of such defaulted interest plus any interest thereon, interest
shall no longer accrue on such defaulted interest pursuant to this Section 2.12. 
 Section 2.13. CUSIP Numbers.
The Company in issuing the Securities may use one or more “CUSIP” numbers, and, if so, the Trustee shall use the CUSIP numbers in notices as a convenience to Holders; provided, however, that no representation is hereby
deemed to be made by the Trustee as to the correctness or accuracy of the CUSIP numbers printed on the notice or on the Securities; and provided further that reliance may be placed only on the other identification numbers printed on the
Securities, and the effectiveness of any such notice shall not be affected by any defect in, or omission of, such CUSIP numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP numbers. 

  
 17 

 On the Issue Date, the Securities shall initially bear the CUSIP and ISIN numbers set forth in
the following sentence. The CUSIP and ISIN numbers for the Atairos Global Securities that are Restricted Global Securities shall be 399473 AC1 and US399473AC18, respectively; the CUSIP and ISIN numbers for the Atairos Global Securities that are
Unrestricted Global Securities shall be 399473 AD9 and US399473AD90, respectively; the CUSIP and ISIN numbers for Restricted Global Securities other than Atairos Global Securities shall be 399473 AA5 and US399473AA51, respectively; and the CUSIP and
ISIN numbers for Unrestricted Global Securities other than Atairos Global Securities shall be 399473 AB3 and US399473AB35, respectively. 

Section 2.14. Deposit of Moneys. Prior to 10:00 a.m., New York City time, on each Interest Payment Date, the Maturity Date or any
Fundamental Change Repurchase Date or Redemption Date, the Company shall deposit with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust in accordance with Section 2.04) money, in funds immediately
available on such date, sufficient to make cash payments, if any, due on such Interest Payment Date, the Maturity Date or such Fundamental Change Repurchase Date or Redemption Date, as the case may be, in a timely manner which permits the Paying
Agent to remit payment to the Holders on such Interest Payment Date, the Maturity Date or such Fundamental Change Repurchase Date or Redemption Date, as the case may be. 

If any Interest Payment Date, the Maturity Date or any Fundamental Change Repurchase Date or Redemption Date falls on a date that is not a
Business Day, the payment due on such Interest Payment Date, the Maturity Date or such Fundamental Change Repurchase Date or Redemption Date, as the case may be, shall be postponed until the next succeeding Business Day, and no interest or other
amount shall accrue as a result of such postponement. 
 Section 2.15. Book-Entry Provisions for Global Securities.
(a) Global Securities initially shall (i) be registered in the name of the Depository, its successors or their respective nominees, (ii) be delivered to the Trustee as custodian for the Depository, its successors or their respective
nominees, as the case may be, and (iii) bear the legends that such Global Securities are required to bear under Section 2.17. 

Members of, or participants in, the Depository (“Participants”) shall have no rights under this Indenture with respect to any
Global Security held on their behalf by the Depository, or the Trustee as its custodian, or under the Global Security, and the Depository (or its nominee) may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the
absolute owner of the Global Security for all purposes whatsoever; provided, however, that each Atairos Global Security shall be subject to the rights under Section 9.02, Section 10.02(c) and Section 13.01 of the
beneficial owners of such Atairos Global Security. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, any Securities Agent or any of their respective agents from giving effect to any written certification, proxy or
other authorization furnished by the Depository or impair, as between the Depository and Participants, the operation of customary practices governing the exercise of the rights of a Holder of any Security. 

  
 18 

 (b) Except as otherwise set forth in this Section 2.15 or Section 2.16, transfers of
Global Securities shall be limited to transfers in whole, but not in part, to the Depository, its successors or their respective nominees. In addition, one or more Physical Securities shall be transferred to each owner of a beneficial interest in a
Global Security, as identified by the Depository, in exchange for its beneficial interest in the Global Securities if (i) the Depository notifies the Company that the Depository is unwilling or unable to continue as depository for any Global
Security, or the Depository ceases to be a “clearing agency” registered under Section 17A of the Exchange Act, and, in either case, a successor Depository is not appointed by the Company within ninety (90) days of such notice or
cessation or (ii) an Event of Default has occurred and is continuing and the Registrar has received a written request from the beneficial owner (via the Depository) of the relevant Securities to issue Physical Securities. For the avoidance of
doubt, if any event described in clause (i) of the immediately preceding sentence occurs, any owner of a beneficial interest in any Global Security will be entitled to receive one or more Physical Securities in exchange for its beneficial
interest or interests in the Global Securities, and if any event described in clause (ii) of the immediately preceding sentence occurs, only the beneficial owner that has made a written request to the Registrar (via the Depository) will be
entitled to receive one or more Physical Securities in exchange for its beneficial interest or interests in the Global Securities. The Company may also exchange beneficial interests in a Global Security for one or more Physical Securities registered
in the name of the owner of beneficial interests if the Company and the owner of such beneficial interests agree to so exchange. 
 (c) The
transfer and exchange of beneficial interests in the Global Securities shall be effected through the Depository, in accordance with the provisions of this Indenture and the Applicable Procedures. Transfers of beneficial interests in the Global
Securities also shall require compliance with either subparagraph (i) or (ii) below, as applicable, as well as, to the extent applicable, the other provisions of this Section 2.15(c) that follow: 

(i) Transfer of Beneficial Interests in the Same Global Security. Beneficial interests in any Restricted Global Security
may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Security (or a Restricted Global Security with the same CUSIP number) in accordance with the transfer restrictions set forth
in the Security Private Placement Legend. Beneficial interests in any Unrestricted Global Security may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Unrestricted Global Security (or an
Unrestricted Global Security with the same CUSIP number). No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this clause (i). 

(ii) All Other Transfers and Exchanges of Beneficial Interests in Global Securities. In connection with all transfers
and exchanges of a beneficial interest in a Global Security that are not addressed by Section 2.15(c)(i), there must be delivered (A) such instruction or order from a Participant or an Indirect Participant to the Depository, as may be
required by the Applicable Procedures, directing the Depository to credit or cause to be credited a beneficial interest in another Global Security in an amount equal to the beneficial interest to be transferred or exchanged and (B) instructions
given in 

  
 19 

 
accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase. Upon satisfaction of all of the requirements for transfer or
exchange of beneficial interests in a Global Security contained in this Indenture, the Trustee shall adjust the principal amount of the Global Securities pursuant to Section 2.15(d). 

(iii) Transfer and Exchange of Beneficial Interests in a Restricted Global Security for Beneficial Interests in an
Unrestricted Global Security. A beneficial interest in any Restricted Global Security may be exchanged by any holder thereof for a beneficial interest in an Unrestricted Global Security or transferred to a Person who takes delivery thereof in
the form of a beneficial interest in an Unrestricted Global Security if the exchange or transfer complies with the requirements of this Section 2.15(c) and the Registrar receives the following: 

(A) if the holder of such beneficial interest in a Restricted Global Security proposes to exchange such beneficial interest for
a beneficial interest in an Unrestricted Global Security, a certificate from such Holder substantially in the form of Exhibit E; or 

(B) if the holder of such beneficial interest in a Restricted Global Security proposes to transfer such beneficial interest to
a Person who shall take delivery thereof in the form of a beneficial interest in an Unrestricted Global Security, a certificate from such holder in the form of Exhibit D; 

and, in each such case set forth in this clause (iii) (other than an exchange or transfer pursuant to an effective registration statement
of the Company or Rule 144 under the Securities Act), if the Registrar so requests or if the Applicable Procedures so require, an Opinion of Counsel in form reasonably acceptable to the Company to the effect that no registration under the Securities
Act is required in connection with such exchange or transfer of beneficial interests to the relevant Person or in connection with any re-sales of the beneficial interests in the Unrestricted Global Security that are beneficially owned by such Person
on the date of such opinion. 
 Beneficial interests in an Unrestricted Global Security cannot be exchanged for, or transferred to Persons
who take delivery thereof in the form of, a beneficial interest in a Restricted Global Security. 
 (iv) Transfer and
Exchange of Beneficial Interests in one Restricted Global Security for Beneficial Interests in another Restricted Global Security. A beneficial interest in any Restricted Global Security may be exchanged by any holder thereof for a beneficial
interest in a Restricted Global Security with a different CUSIP number or different legends or transferred to a Person who takes delivery thereof in the form of a beneficial interest in a Restricted Global Security with a different CUSIP number or
different legends if the exchange or transfer complies with the requirements of this Section 2.15(c) and the Registrar receives the following: 

(A) if the holder of such beneficial interest in a Restricted Global Security proposes to exchange such beneficial interest for
a beneficial interest in a Restricted Global Security with a different CUSIP number or different legends, a certificate from such Holder substantially in the form of Exhibit E; or 

  
 20 

 (B) if the holder of such beneficial interest in a Restricted Global Security
proposes to transfer such beneficial interest to a Person who shall take delivery thereof in the form of a beneficial interest in a Restricted Global Security with a different CUSIP number or different legends, a certificate from such holder in the
form of Exhibit D. 
 Notwithstanding the foregoing or anything to the contrary provided herein, a holder of a beneficial interest in
a Security that is not an Atairos Security may not exchange or transfer such beneficial interest for a beneficial interest in an Atairos Security. 

(d) At such time as all beneficial interests in a particular Global Security have been exchanged for Physical Securities or a particular
Global Security has been repurchased or canceled in whole and not in part, each such Global Security shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11. At any time prior to such cancellation, if any
beneficial interest in a Global Security is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Security or for Physical Securities, the principal amount of Securities
represented by such Global Security shall be reduced accordingly and an endorsement shall be made on such Global Security by the Trustee or by the Depository at the direction of the Trustee to reflect such reduction; and if the beneficial interest
is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Security, such other Global Security shall be increased accordingly and an endorsement shall be made on such
Global Security by the Trustee or by the Depository at the direction of the Trustee to reflect such increase. 
 (e) In connection with the
transfer of a Global Security in its entirety to beneficial owners pursuant to Section 2.15(b), such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall upon
written instructions from the Company authenticate and deliver, to each beneficial owner identified by the Depository in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Physical Securities of
authorized denominations. 
 (f) Any Physical Security delivered in exchange for an interest in a Global Security pursuant to
Section 2.15(b), shall bear the same legend(s), if any, from Exhibit B-1A that are borne by the relevant Global Security, except to the extent the requirements of Section 2.15(c)(iii) or Section 2.15(c)(iv) are satisfied with
respect to the removal or addition of any legend, mutatis mutandis for the fact that a Physical Security is being issued rather than a beneficial interest in a Global Security. 

  
 21 

 (g) The Holder of any Global Security may grant proxies and otherwise authorize any Person,
including Participants and Persons that may hold interests through Participants, to take any action which a Holder is entitled to take under this Indenture or the Securities. 

(h) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on the transfer of
any interest in any Securities imposed under this Indenture or under applicable law (including any transfers between or among Participants or beneficial owners of interests in any Global Security) other than to require delivery of such certificates
and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements
hereof. 
 (i) Neither the Trustee nor any Securities Agent shall have any responsibility for any actions taken or not taken by the
Depository. 
 (j) No service charge shall be made to or by a holder of a beneficial interest in a Global Security or to or by a Holder of a
Physical Security for any registration of transfer or exchange. 
 (k) All Global Securities and Physical Securities issued upon any
registration of transfer or exchange of Global Securities or Physical Securities shall evidence the same debt of the Company and shall be entitled to the same benefits under this Indenture as the Global Securities or Physical Securities surrendered
upon such registration of transfer or exchange. 
 (l) Prior to due presentment for the registration of a transfer of any Security, the
Trustee and the Company may deem and treat the Person in whose name any Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest on such Securities and, subject to
Section 2.09, for all other purposes, and neither of the Trustee or the Company shall be affected by notice to the contrary. 
 (m)
Upon surrender for registration of transfer of any Security at the office or agency of the Company designated pursuant to Section 4.02, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more replacement Securities of any authorized denomination or denominations of a like aggregate principal amount. 

(n) At the option of the Holder, Securities may be exchanged for other Securities of any authorized denomination or denominations of a like
aggregate principal amount upon surrender of the Securities to be exchanged at such office or agency. Whenever any Global Securities or Physical Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and send, the replacement Global Securities and Physical Securities which the Holder making the exchange is entitled to in accordance with the provisions of Section 2.02. 

(o) Neither the Trustee nor any Securities Agent shall have any responsibility or obligation to any beneficial owner of an interest in the
Global Securities, an agent member of, 

  
 22 

 
or a participant in, the Depository or other person with respect to the accuracy of the records of the Depository or its nominees or of any Participant or member thereof, with respect to any
ownership interest in the Global Securities or with respect to the delivery to any Participant, agent member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of redemption) or the payment of any
amount or delivery of any Securities (or other security or property) under or with respect to such Securities. The rights of beneficial owners in any Global Securities shall be exercised only through the Depository, subject to its applicable rules
and procedures. The Trustee and each agent may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its agent members and Participants and any beneficial owners of Global Securities. 

Section 2.16. Special Transfer Provisions. (a) Notwithstanding any other provisions of this Indenture, but except as provided
in Section 2.15(b), a Global Security may not be transferred except as a whole by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any
such nominee to a successor Depository or a nominee of such successor Depository. 
 (b) Upon the transfer, exchange or replacement of
Securities not bearing the Security Private Placement Legend, unless the Company notifies the Trustee in writing otherwise, the Trustee shall deliver Securities that do not bear the Security Private Placement Legend. Upon the transfer, exchange or
replacement of Securities bearing the Security Private Placement Legend, the Trustee shall deliver only Securities that bear the Security Private Placement Legend unless (i) the requested transfer, exchange or replacement is after the Resale
Restriction Termination Date, (ii) there is delivered to the Trustee and the Company an Opinion of Counsel reasonably satisfactory to the Company and addressed to the Company to the effect that no registration under the Securities Act is
required in connection with such transfer, exchange or replacement of such Securities in connection with any re-sales of such Securities on the date of such opinion, (iii) such Security has been sold pursuant to an effective registration
statement under the Securities Act and the Holder selling such Securities has delivered to the Registrar a notice in the form of Exhibit C hereto or (iv) such Security has been sold pursuant to Rule 144 under the Securities Act and the
Holder selling such Securities has delivered to the Registrar a notice in the form of Exhibit D hereto. 
 (c) By its acceptance
of any Security or any Common Stock bearing the Security Private Placement Legend or the Common Stock Private Placement Legend, each holder thereof acknowledges the restrictions on transfer of such security set forth in this Indenture and in the
Security Private Placement Legend or Common Stock Private Placement Legend, as applicable, and agrees that it will transfer such security only as provided in this Indenture and as permitted by applicable law. 

The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.15 or this
Section 2.16 in accordance with its customary document retention policies. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of
reasonable written notice to the Registrar. 

  
 23 

 (d) The Company may, to the extent permitted by law, purchase the Securities in the open market
or by tender offer at any price or by private agreement without giving prior notice to Holders. The Company may, at its option, surrender to the Trustee for cancellation any Securities the Company purchases in this manner. Securities surrendered to
the Trustee for cancellation may not be reissued or resold and shall be promptly cancelled pursuant to Section 2.11. 

Section 2.17. Restrictive Legends. 

(a) Each Global Security and Physical Security that constitutes a Restricted Security shall bear the legend (the “Security Private
Placement Legend”) as set forth in Exhibit B-1A on the face thereof until the date such Securities no longer constitute Restricted Securities as reasonably determined by the Company in good faith (but, in any event, no later than the
first anniversary of the Issue Date) and evidenced by an Officers’ Certificate (such date, the “Resale Restriction Termination Date”). 

No transfer of any Restricted Security prior to the Resale Restriction Termination Date will be registered by the Registrar unless the
applicable box on the Form of Assignment has been checked. 
 Any Security (or security issued in exchange or substitution therefor)
(i) as to which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become effective or been declared effective under the Securities
Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to Rule 144 under the Securities Act or any similar provision then in force, may, upon surrender of such Security for exchange to the
Trustee in accordance with the provisions of this Article 2, be exchanged for a new Security or Securities, of like tenor and aggregate principal amount, which shall not bear the Security Private Placement Legend required by this
Section 2.17(a) and shall not be assigned a restricted CUSIP number. In addition, on or after the Resale Restriction Termination Date, upon the request of any Holder and upon surrender of its Security for exchange, the Company shall exchange a
Physical Security with the Security Private Placement Legend for a Physical Security without the Security Private Placement Legend so long as the Holder covenants to the Company that it will offer, sell, pledge or otherwise transfer such Security in
compliance with the Securities Act. The Company shall be entitled to instruct the Trustee in writing to cancel any Global Security as to which such restrictions on transfer shall have expired in accordance with their terms for exchange, and, upon
such instruction, the Trustee shall provide evidence of cancellation of such Global Security; and any new Global Security exchanged therefor shall not bear the Security Private Placement Legend specified in this Section 2.17(a) and shall not be
assigned a restricted CUSIP number. The Company shall promptly notify the Trustee in writing upon the occurrence of the Resale Restriction Termination Date and promptly after a registration statement, if any, with respect to the Securities or any
Common Stock issued upon conversion of the Securities has been declared effective under the Securities Act. 
 (b) Until the Resale
Restriction Termination Date, any stock certificate representing Common Stock issued upon conversion of a Security, if any, shall, if such shares constitute 

  
 24 

 
Restricted Securities at their time of issuance, bear the legend (the “Common Stock Private Placement Legend”) as set forth in Exhibit B-1B unless (i) such Common
Stock has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, (ii) such Common Stock has been sold pursuant
to Rule 144 under the Securities Act or any similar provision then in force, (iii) such Common Stock has been issued upon conversion of a Security that has been transferred pursuant to a registration statement that has become or been declared
effective under the Securities Act and that continues to be effective at the time of such transfer, or pursuant to Rule 144 under the Securities Act or any similar provision then in force or (iv) otherwise agreed by the Company in writing. 

(c) Each Global Security shall also bear the legend as set forth in Exhibit B-2. 

ARTICLE 3 
 REPURCHASE 

Section 3.01. Repurchase at Option of Holder Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time prior
to the Maturity Date, each Holder of Securities shall have the right (the “Fundamental Change Repurchase Right”), at such Holder’s option, to require the Company to repurchase (a “Repurchase Upon Fundamental
Change”) all of such Holder’s Securities (or any portion thereof that is equal to $1,000 in principal amount or an integral multiples of $1,000 in excess thereof), on a date selected by the Company (the “Fundamental Change
Repurchase Date”), which shall be no later than thirty five (35) Business Days, and no earlier than twenty (20) Business Days (or as such period may be extended pursuant to Section 3.01(j)), after the date the Fundamental
Change Notice is sent in accordance with Section 3.01(b), at a price, payable in cash, equal to one hundred percent (100%) of the principal amount of the Securities (or portion thereof) to be so repurchased, plus accrued and unpaid
interest, if any, to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), subject to satisfaction of the following conditions: 

(i) delivery to the Company (if it is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such
purpose in the Fundamental Change Notice, no later than the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date, of a Repurchase Notice, in the form set forth in the Securities or any other form of
written notice substantially similar thereto, in each case, duly completed and signed, with appropriate signature guarantee, stating: 

(A) the certificate number(s) of the Securities that the Holder will deliver to be repurchased, if such Securities are Physical
Securities; 
 (B) the principal amount of Securities to be repurchased, which must be $1,000 or an integral multiple
thereof; and 
 (C) that such principal amount of Securities are to be repurchased pursuant to the terms and conditions
specified in this Section 3.01; and 

  
 25 

 (ii) delivery to the Company (if it is acting as its own Paying Agent), or to a
Paying Agent designated by the Company for such purpose in the Fundamental Change Notice, at any time after the delivery of such Repurchase Notice, of such Securities (together with all necessary endorsements) with respect to which the Fundamental
Change Repurchase Right is being exercised, if such Securities are Physical Securities, or book-entry transfer of the Securities, if the Securities are Global Securities, in compliance with the Applicable Procedures; 

provided, however, that if such Fundamental Change Repurchase Date is after a Record Date for the payment of an installment of interest and on
or before the related Interest Payment Date, then the full amount of accrued and unpaid interest, if any, to, but excluding, such Interest Payment Date shall be paid on such Interest Payment Date to the Holder of record of such Securities at the
Close of Business on such Record Date (without any surrender of such Securities by such Holder), and the Fundamental Change Repurchase Price shall not include any accrued but unpaid interest. 

If such Securities are held in book-entry form through the Depository, the delivery of any Securities, Repurchase Notice, Fundamental Change
Notice or notice of withdrawal pursuant to the immediately succeeding paragraph shall comply with the Applicable Procedures. 

Notwithstanding anything herein to the contrary, any Holder that has delivered the Repurchase Notice contemplated by this Section 3.01(a)
to the Company (if it is acting as its own Paying Agent) or to a Paying Agent designated by the Company for such purpose in the Fundamental Change Notice shall have the right to withdraw such Repurchase Notice by delivery, at any time prior to the
Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date (or, if there shall be a Default in the payment of the Fundamental Change Repurchase Price, at any time during which such Default is continuing), of a
written notice of withdrawal to the Company (if acting as its own Paying Agent) or the Paying Agent, which notice shall be delivered in accordance with, and contain the information specified in, Section 3.01(b)(x). 

The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase Notice or written notice of withdrawal thereof. 

(b) On or before the 20th Business Day after the consummation of a Fundamental Change, the Company shall send, or cause to be sent, to all
Holders of the Securities in accordance with Section 14.01 a notice (the “Fundamental Change Notice”) of the occurrence of such Fundamental Change and the Fundamental Change Repurchase Right arising as a result thereof. The
Company shall deliver a copy of the Fundamental Change Notice to the Trustee at the time such notice is delivered to the Holders. Each Fundamental Change Notice shall state: 

(i) the events causing the Fundamental Change; 

(ii) the date of the Fundamental Change; 

  
 26 

 (iii) the Fundamental Change Repurchase Date; 

(iv) the last date on which the Fundamental Change Repurchase Right may be exercised, which shall be the Business Day
immediately preceding the Fundamental Change Repurchase Date; 
 (v) the Fundamental Change Repurchase Price; 

(vi) the names and addresses of the Paying Agent and the Conversion Agent; 

(vii) the procedures that a Holder must follow to exercise the Fundamental Change Repurchase Right; 

(viii) that the Fundamental Change Repurchase Price for any Security as to which a Repurchase Notice has been given and not
withdrawn will be paid no later than the later of such Fundamental Change Repurchase Date and the time of book-entry transfer or delivery of the Security (together with all necessary endorsements); 

(ix) that, except as otherwise provided herein with respect to a Fundamental Change Repurchase Date that is after a Record Date
for the payment of an installment of interest and on or before the related Interest Payment Date, on and after such Fundamental Change Repurchase Date (unless there shall be a Default in the payment of the Fundamental Change Repurchase Price),
interest on Securities subject to Repurchase Upon Fundamental Change will cease to accrue, and all rights of the Holders of such Securities shall terminate, other than the right to receive, in accordance herewith, the Fundamental Change Repurchase
Price; 
 (x) that a Holder will be entitled to withdraw its election in the Repurchase Notice prior to the Close of Business
on the Business Day immediately preceding the Fundamental Change Repurchase Date, or such longer period as may be required by law, delivered in the same manner as the related Repurchase Notice was delivered and setting forth the name of such Holder,
a statement that such Holder is withdrawing its election to have Securities purchased by the Company on such Fundamental Change Repurchase Date pursuant to a Repurchase Upon Fundamental Change, the certificate number(s) of such Securities to be so
withdrawn (if such Securities are Physical Securities) the principal amount of the Securities of such Holder to be so withdrawn, which amount must be $1,000 or an integral multiple thereof and the principal amount, if any, of the Securities of such
Holder that remain subject to the Repurchase Notice delivered by such Holder in accordance with this Section 3.01, which amount must be $1,000 or an integral multiple thereof; provided, however, that if there shall be a Default in
the payment of the Fundamental Change Repurchase Price, a Holder shall be entitled to withdraw its election in the Repurchase Notice at any time during which such Default is continuing; 

(xi) the Conversion Rate and any adjustments to the Conversion Rate that will result from such Fundamental Change; 

  
 27 

 (xii) that Securities with respect to which a Repurchase Notice is given by a
Holder may be converted pursuant to Article 10 only if such Repurchase Notice has been withdrawn in accordance with this Section 3.01 or the Company defaults in the payment of the Fundamental Change Repurchase Price; and 

(xiii) the CUSIP number or numbers, as the case may be, of the Securities. 

At the Company’s request, upon prior notice reasonably acceptable to the Trustee, the Trustee shall send such Fundamental Change Notice
to the Holders in the Company’s name and at the Company’s expense; provided, however, that the form and content of such Fundamental Change Notice shall be prepared by the Company. 

No failure of the Company to give a Fundamental Change Notice shall limit any Holder’s right pursuant hereto to exercise a Fundamental
Change Repurchase Right. 
 (c) Subject to the provisions of this Section 3.01, the Company shall pay, or cause to be paid, the
Fundamental Change Repurchase Price with respect to each Security as to which the Fundamental Change Repurchase Right shall have been exercised to the Holder thereof no later than the later of the Fundamental Change Repurchase Date and the time of
book-entry transfer or when such Security is surrendered to the Paying Agent together with any necessary endorsements. 
 (d) The Company
shall, in accordance with Section 2.14, deposit with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust in accordance with Section 2.04) money, in funds immediately available on the
Fundamental Change Repurchase Date, sufficient to pay the Fundamental Change Repurchase Price upon a Repurchase Upon Fundamental Change for all of the Securities that are to be repurchased by the Company on such Fundamental Change Repurchase Date
pursuant to a Repurchase Upon Fundamental Change. The Paying Agent shall, promptly after delivering the Fundamental Change Repurchase Price to Holders entitled thereto and upon written demand by the Company, return to the Company as soon as
practicable, any money in excess of the Fundamental Change Repurchase Price. 
 (e) Once the Fundamental Change Notice and the Repurchase
Notice have been duly given in accordance with this Section 3.01, the Securities to be repurchased pursuant to a Repurchase Upon Fundamental Change shall, on the Fundamental Change Repurchase Date, become due and payable in accordance herewith,
and, on and after such date (unless there shall be a Default in the payment of the Fundamental Change Repurchase Price), except as otherwise provided herein with respect to a Fundamental Change Repurchase Date that is after a Record Date for the
payment of an installment of interest and on or before the related Interest Payment Date, such Securities shall cease to bear interest (whether or not book-entry transfer of the Securities has been made or the Securities have been delivered to the
Paying Agent), and all rights of the relevant Holders of such Securities shall terminate, other than the right to receive, in accordance herewith, such payments and any other applicable rights under those sections set forth in the proviso in
Section 8.01. 

  
 28 

 (f) Securities with respect to which a Repurchase Notice has been duly delivered in accordance
with this Section 3.01 may be converted pursuant to Article 10 only if such Repurchase Notice has been withdrawn in accordance with this Section 3.01 or the Company defaults in the payment of the Fundamental Change Repurchase Price. 

(g) If any Security shall not be paid on the Fundamental Change Repurchase Date upon book-entry transfer or surrender thereof for Repurchase
Upon Fundamental Change, the principal of, and accrued and unpaid interest on, such Security shall, until paid, bear interest, payable in cash, at the rate borne by such Security on the principal amount of such Security, and such Security shall be
convertible pursuant to Article 10 if any Repurchase Notice with respect to such Security is withdrawn pursuant to this Section 3.01. 

(h) Any Security that is to be submitted for Repurchase Upon Fundamental Change only in part shall be delivered pursuant to this
Section 3.01 (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 its attorney duly authorized in
writing, with a notarization or medallion guarantee), and the Company shall promptly execute, and the Trustee shall promptly authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or
Securities, of any authorized denomination as requested by such Holder, of the same tenor and in aggregate principal amount equal to the portion of such Security not duly submitted for Repurchase Upon Fundamental Change. 

(i) Notwithstanding anything herein to the contrary, except in the case of an acceleration resulting from a Default relating to the payment of
the Fundamental Change Repurchase Price, there shall be no purchase of any Securities pursuant to this Section 3.01 on any date if, on such date, the principal amount of the Securities shall have been accelerated in accordance with this
Indenture and such acceleration shall not have been rescinded on or prior to such date in accordance with this Indenture. The Paying Agent will promptly return to the respective Holders thereof any Securities held by it during the continuance of
such an acceleration. 
 (j) In connection with any Repurchase Upon Fundamental Change, the Company shall, to the extent required:
(i) comply with the provisions of Rule 13e-4, Rule 14e-1 and Regulation 14E under the Exchange Act, and with all other applicable laws; (ii) file a Schedule TO or any other schedules required under the Exchange Act or any other applicable
laws; and (iii) otherwise comply with all applicable United States federal and state securities laws in connection with any offer by the Company to repurchase the Securities; provided that any time period specified in this Article 3
shall be extended to the extent necessary for such compliance. 
 ARTICLE 4 

COVENANTS 

Section 4.01. Payment of Securities. The Company shall pay all amounts and make deliveries of securities due with respect
to the Securities on the dates and in the manner provided in the Securities and this Indenture. All such amounts shall be considered paid on the date due if 

  
 29 

 
the Paying Agent holds (or, if the Company is acting as Paying Agent, the Company has segregated and holds in trust in accordance with Section 2.04) on that date money sufficient to pay the
amount then due with respect to the Securities. The Company will pay, in money of the United States that at the time of payment is legal tender for payment of public and private debts, all amounts due in cash with respect to the Securities, which
amounts shall be paid: (a) in the case of a Global Security, by wire transfer of immediately available funds to the account designated by the Depository or its nominee; and (b) in the case of a Physical Security, by wire transfer of
immediately available funds to the account within the United States as specified in writing to the Paying Agent by such Holder or, if such Holder does not specify an account, by mailing a check to the address of such Holder set forth in the register
of the Registrar. With respect to principal payments, presentation and surrender of Securities is required prior to final payment. 
 The
Company shall pay, in cash, interest on any overdue amount (including, to the extent permitted by applicable law, overdue interest) at the rate borne by the Securities. 

Section 4.02. Maintenance of Office or Agency. The Company will maintain, or cause to be maintained, an office or agency
(which may be an office of the Trustee or an Affiliate of the Trustee or Registrar) where Securities may be surrendered for registration of transfer or exchange, payment or conversion. The Company will give prompt written notice to the Trustee of
the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain, or fail to cause to be maintained, any such required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations and surrenders may be made or served at the Corporate Trust Office of the Trustee. 
 The Company will maintain,
or cause to be maintained, an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture (other than the type contemplated by Section 14.09(c)) may be served, provided that such office or
agency may instead be at the principal office of the Company located in the United States (and, notwithstanding the final sentence of this Section 4.02, shall initially be at such office until the Company notifies the Trustee otherwise). 

The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered
for any or all such purposes and may from time to time rescind such designations. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

 The Company hereby initially designates the Corporate Trust Office of the Trustee as an agency of the Company in accordance with
Section 2.03. 
 Section 4.03. Annual Reports. (a) The Company shall provide to the Trustee a copy of each report the
Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act no later than the date 15 Business Days after such report is required to be filed with the SEC pursuant to the Exchange Act (after giving effect to any
grace period provided by Rule 12b-25 under the Exchange Act); provided, however, that each such report will be deemed 

  
 30 

 
to be so provided to the Trustee if the Company files such report with the SEC through the SEC’s EDGAR database no later than the time such report is required to be filed with the SEC
pursuant to the Exchange Act (taking into account any applicable grace periods provided thereunder). To the extent the TIA then applies to this Indenture, the Company shall comply with TIA §314(a). In addition, while the Securities remain
outstanding and are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, the Company will, during any period in which the Company is not subject to Section 13 or 15(d) of the Exchange Act, furnish to
holders of the Securities and prospective investors, upon request, the information required to be delivered pursuant to 
Rule 144A(d)(4) under the Securities Act. 

(b) Delivery of such reports, information and documents to the Trustee pursuant to this Section 4.03 is for informational purposes only,
and the Trustee’s receipt of such shall not constitute actual or constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants
hereunder (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate). 
 (c) The Trustee shall have no
obligation or duty to determine or monitor whether the Company has delivered reports in accordance with this Section 4.03. 
 (d) If,
at any time during the six-month period beginning on, and including, the date that is six months after the Issue Date, the Company fails to timely file any document or report that it is required to file with the SEC pursuant to Section 13 or
15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K), or the Securities are not otherwise freely tradable by Holders other than the Company’s Affiliates or
Holders that were the Company’s Affiliates at any time during the three months immediately preceding (as a result of restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Securities), the Company shall pay
Additional Interest on the Securities. Such Additional Interest shall accrue on the Securities at the rate of 0.50% per annum of the principal amount of the Securities outstanding for each day during the period for which the Company’s
failure to file has occurred and is continuing or the Securities are not otherwise freely tradable by Holders other than the Company’s Affiliates (or Holders that have been the Company’s Affiliates at any time during the three months
immediately preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Securities. As used in this Section 4.03(d), documents or reports that the Company is required to “file” with the SEC
pursuant to Section 13 or 15(d) of the Exchange Act do not include documents or reports that the Company furnishes to the SEC pursuant to Section 13 or 15(d) of the Exchange Act. 

(e) If, and for so long as, the Security Private Placement Legend has not been removed, the Securities are assigned a restricted CUSIP number
or the Securities are not otherwise freely tradable by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding (without restrictions pursuant to
U.S. securities laws or the terms of this Indenture or the Securities) as of the 365th day after the Issue Date, the Company shall pay Additional Interest on the Securities at a rate equal to 0.50% per annum of the principal amount of
Securities outstanding 

  
 31 

 
until the Security Private Placement Legend has been removed, the Securities are assigned an unrestricted CUSIP number and the Securities are freely tradable by Holders other than the
Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Securities. 

(f) Additional Interest will be payable in arrears on each Interest Payment Date following accrual thereof in the same manner as regular
interest on the Securities. 
 (g) The Additional Interest that is payable in accordance with Section 4.03(d) or Section 4.03(e)
shall, subject to the immediately succeeding sentence, be in addition to, and not in lieu of, any Additional Interest that may be payable as a result of the Company’s election pursuant to 6.02(b). However, in no event shall any Additional
Interest that may accrue as a result of the Company’s failure to timely file any document or report that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect
to all applicable grace periods thereunder and other than reports on Form 8-K), as described in Section 4.03(d), together with any interest that may accrue in the event the Company elects to pay Additional Interest in respect of an Event of
Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.03(a) pursuant to Section 6.02(b), accrue at a rate in excess of 0.50% per annum pursuant to this Indenture, regardless of the
number of events or circumstances giving rise to the requirement to pay such Additional Interest. 
 (h) If the Company is required to pay
Additional Interest to Holders, the Company shall provide a direction or order in the form of a written notice to the Trustee (and if the Trustee is not the Paying Agent, to the Paying Agent) of the Company’s obligation to pay such Additional
Interest no later than three Business Days prior to the date on which any such Additional Interest is scheduled to be paid. Such notice shall set forth the amount of Additional Interest to be paid by the Company on such payment date and direct the
Trustee (or, if the Trustee is not the Paying Agent, to the Paying Agent) to make payment to the extent it receives funds from the Company to do so. The Trustee shall not at any time be under any duty or responsibility to any Holder to determine
whether the Additional Interest is payable, or with respect to the nature, extent or calculation of the amount of the Additional Interest owed, or with respect to the method employed in such calculation of the Additional Interest. 

Section 4.04. Compliance Certificate. The Company shall deliver to the Trustee, within one hundred and twenty (120) calendar
days after the end of each fiscal year of the Company, commencing with the fiscal year ending December 31, 2016, a certificate from the principal executive, financial or accounting officer of the Company stating that such officer has conducted
or supervised a review of the activities of the Company and its performance of obligations under this Indenture and the Securities and that, based upon such review, no Default or Event of Default exists hereunder or thereunder or, if a Default or
Event of Default then exists, specifying such event, status and the remedial action proposed to be taken by the Company with respect to such Default or Event of Default. 

  
 32 

 Section 4.05. Stay, Extension and Usury Laws. The Company covenants (to the extent
that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture or the Securities; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to
any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted. 

Section 4.06. Notice of Default. Within 30 days of the Company’s becoming aware of the occurrence of any Default or Event of
Default, the Company shall give written notice to the Trustee of such Default or Event of Default, and any remedial action proposed to be taken. 

ARTICLE 5 
 SUCCESSORS

 Section 5.01. When Company May Merge, Etc. Subject to Section 5.02, the Company shall not consolidate with, or merge
with or into, or sell, transfer, lease, convey or otherwise dispose of all or substantially all of the consolidated property or assets of the Company and its Subsidiaries, taken as a whole, to another Person (other than one or more Wholly Owned
Subsidiaries of the Company (it being understood that this Article 5 shall not apply to a sale, transfer, lease, conveyance or other disposition of property or assets between or among the Company and its Wholly Owned Subsidiaries)), whether in a
single transaction or series of related transactions, unless (i)(x) the Company is the continuing Person or (y) such other Person is a corporation organized and existing under the laws of the United States of America, any state of the United
States of America or the District of Columbia, such other Person assumes by supplemental indenture all of the obligations of the Company under the Securities and this Indenture and following such transaction or series of related transactions the
Reference Property does not include interests in an entity that is a partnership for U.S. federal income tax purposes and (ii) immediately after giving effect to such transaction or series of transactions, no Default or Event of Default shall
have occurred and be continuing under this Indenture. 
 For purposes of this Section 5.01, the sale, transfer, lease, conveyance or
other disposition of all or substantially all of the properties or assets of one or more Subsidiaries of the Company to another Person other than the Company or one or more other Wholly Owned Subsidiaries of the Company, which properties or assets,
if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the consolidated properties or assets of the Company and its Subsidiaries, taken as a whole, shall be deemed to be the sale, transfer, lease,
conveyance or other disposition of all or substantially all of the consolidated properties or assets of the Company and its Subsidiaries, taken as a whole, to another Person. 

The Company shall deliver to the Trustee substantially concurrently with or prior to the consummation of the proposed transaction an
Officers’ Certificate and an Opinion of Counsel (which may rely upon such Officers’ Certificate as to the absence of Defaults and Events of Default and other statements of fact) stating that the proposed transaction and, if required, such
supplemental indenture (if any) will, upon consummation of the proposed transaction, comply with the applicable provisions of this Indenture. 

  
 33 

 Section 5.02. Successor Substituted. In case of any such consolidation, merger or any
sale, transfer, lease, conveyance or other disposition of all or substantially all of the consolidated property or assets of the Company and its Subsidiaries, taken as a whole, and upon the assumption by the successor Person, by supplemental
indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid interest on all of the Securities, the due and punctual payment of the Fundamental
Change Repurchase Price with respect to all Securities repurchased on each Fundamental Change Repurchase Date, the due and punctual payment of the Redemption Price due on a Redemption Date, the due and punctual delivery or payment, as the case may
be, of any consideration due upon conversion of the Securities and the due and punctual performance of all of the covenants and conditions of this Indenture and the Securities to be performed by the Company, such successor Person shall succeed to
and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such successor Person thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or
all of the Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor Person instead of the Company and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Securities that previously shall have been signed and delivered by the Officers of the Company to the Trustee
for authentication, and any Securities that such successor Person thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Securities so issued shall in all respects have the same legal rank and benefit under this
Indenture as the Securities theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities had been issued at the date of the execution hereof. In the event of any such consolidation, merger or any
sale, transfer, conveyance or other disposition (but not in the case of a lease), upon compliance with this Article 5, the Person named as the “Company” in the first paragraph of this Indenture or any successor that shall thereafter have
become such in the manner prescribed in this Article 5, except in the case of a lease, shall be released from its liabilities as obligor and maker of the Securities and its obligations under this Indenture shall terminate. 

In case of any such consolidation, merger or any sale, transfer, lease, conveyance or other disposition, such changes in phraseology and form
(but not in substance) may be made in the Securities thereafter to be issued as may be appropriate. 
 ARTICLE 6 

DEFAULTS AND REMEDIES 

Section 6.01. Events of Default. An “Event of Default” occurs if: 

(a) the Company fails to pay the principal of any Security when due, whether on the Maturity Date, on a Fundamental Change Repurchase Date
with respect to a Fundamental Change, on a Redemption Date, upon acceleration or otherwise; 

  
 34 

 (b) the Company fails to pay an installment of interest on any Security when due, if the failure
continues for thirty (30) days after the date when due; 
 (c) the Company fails to satisfy its conversion obligations upon exercise of
a Holder’s conversion rights pursuant hereto and such failure continues for a period of three (3) Business Days; 
 (d) the
Company fails to (i) comply with its obligations under Article 5 or (ii) issue a Fundamental Change Notice in accordance with Section 3.01(b) when due; 

(e) the Company fails to comply with any other term, covenant or agreement set forth in the Securities or this Indenture and such failure
continues for the period, and after the notice, specified in the last paragraph of this Section 6.01; 
 (f)(i) the Company fails to
make any payment at maturity, including any applicable grace period, on any indebtedness of the Company (other than indebtedness of the Company owing to any of its Subsidiaries) outstanding in an amount in excess of $40,000,000 (or its foreign
currency equivalent) and continuance of this failure to pay or (ii) there is a default on any indebtedness of the Company (other than indebtedness owing to any of its Subsidiaries), which default results in the acceleration of such indebtedness
in an amount in excess of $40,000,000 (or its foreign currency equivalent) without such indebtedness having been discharged or the acceleration having been cured, waived, rescinded or annulled, in the case of clause (i) or (ii) above, for
a period of 30 days after written notice thereof to the Company by the Trustee or to the Company and the Trustee by Holders of not less than 25% in principal amount of outstanding Securities (provided, however, that if any failure,
default or acceleration referred to in clause (i) or (ii) above ceases or is cured, waived, rescinded or annulled, then the Event of Default will be deemed cured); 

(g) a final judgment or judgments for the payment of $40,000,000 (or its foreign currency equivalent) or more (excluding any amounts covered
by insurance) in the aggregate is rendered against the Company or any Subsidiary of the Company, which judgment is not discharged, paid, bonded, waived or stayed within 30 days after (i) the date on which the right to appeal thereof has expired
if no such appeal has commenced, or (ii) the date on which all rights to appeal have been extinguished; 
 (h) the Company or any
Significant Subsidiary, pursuant to, or within the meaning of, any Bankruptcy Law, insolvency law, or other similar law now or hereafter in effect or otherwise, either: 

(i) commences a voluntary case, 

(ii) consents to the entry of an order for relief against it in an involuntary case, 

(iii) consents to the appointment of a Bankruptcy Custodian of it or for all or substantially all of its property, or 

(iv) makes a general assignment for the benefit of its creditors; or 

  
 35 

 (i) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

 (i) is for relief against the Company or any Significant Subsidiary in an involuntary case or proceeding with respect to
the Company or such Significant Subsidiary, or adjudicates the Company or any Significant Subsidiary insolvent or bankrupt, 

(ii) appoints a Bankruptcy Custodian of the Company or any Significant Subsidiary for all or substantially all of the
consolidated property of the Company or any Significant Subsidiary, as the case may be, or 
 (iii) orders the winding up or
liquidation of the Company or any Significant Subsidiary, 
 and, in the case of each of the foregoing clauses (i), (ii) and
(iii) of this Section 6.01(i), the order or decree remains unstayed and in effect for at least sixty (60) consecutive days. 

A Default under clause (e) above shall not be an Event of Default until (A) the Trustee notifies the Company in writing, or the
Holders of at least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee in writing, of the Default and (B) the Default is not cured within sixty (60) days after
receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that the notice is a “Notice of Default.” If the Holders of at least twenty five percent (25%) in aggregate principal amount of the
outstanding Securities request the Trustee to give such notice on their behalf, the Trustee shall do so. When a Default is cured, it ceases to exist for all purposes under this Indenture. 

Section 6.02. Acceleration. (a) Subject to Section 6.02(b), if applicable, if an Event of Default (excluding an Event of
Default specified in Section 6.01(h) or Section 6.01(i)) has occurred and is continuing, either the Trustee, by written notice to the Company, or the Holders of at least twenty five percent (25%) in aggregate principal amount of the
Securities then outstanding, by written notice to the Company and the Trustee, may declare 100% of the principal of, and accrued and unpaid interest on, all the Securities to be immediately due and payable in full. Upon such declaration, the
principal of, and any accrued and unpaid interest on, all Securities shall be due and payable immediately. If an Event of Default specified in Section 6.01(h) or Section 6.01(i) occurs, 100% of the principal of, and accrued and unpaid
interest on, all the Securities shall automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in aggregate principal amount of the Securities
then outstanding by written notice to the Trustee may rescind or annul an acceleration and its consequences if (i) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction, (ii) all existing Events
of Default, except the nonpayment of principal or interest that has become due solely because of the acceleration, have been cured or waived (or are waived concurrently with such rescission or annulment) and (iii) all amounts due to the Trustee
under Section 7.06 have been paid. Upon any such rescission or annulment, the Events of Default that were the subject of such acceleration 

  
 36 

 
shall cease to exist and deemed to have been cured for every purpose. Notwithstanding anything to the contrary herein, no such rescission and/or annulment shall extend to or shall affect any
Default or Event of Default resulting from (i) the nonpayment of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, any Securities, (ii) a
failure to repurchase any Securities when required or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Securities. 

(b) Notwithstanding the foregoing, for the first 180 days immediately following an Event of Default relating to failure to comply with
Section 4.03(a) or for any failure to comply with the requirements of Section 314(a)(1) of the TIA (at any time such section is applicable to the Indenture) (which will be the 61st day after written notice is provided to the Company of the
Default pursuant to the last paragraph of Section 6.01, unless such failure is cured or waived prior to such 61st day), the sole remedy for any such Event of Default shall, at the Company’s election, be the accrual of Additional Interest
on the Securities at a rate per year equal to (i) 0.25% of the outstanding principal amount of Securities for the first 90 days following the occurrence of such Event of Default and (ii) 0.50% of the outstanding principal amount of
Securities for the next 90 days after the first 90 days following the occurrence of such Event of Default, in each case, payable in the same manner and at the same time as the stated interest payable on the Securities. Such Additional Interest shall
accrue on all outstanding Securities from, and including, the date on which such Event of Default first occurs to, and including, the 180th day thereafter (or such earlier date on which such Event of Default shall have been cured or waived). On and
after the 181st day immediately following an Event of Default relating to a failure to comply with Section 4.03(a), if the Company elected to pay Additional Interest pursuant to this Section 6.02(b) such Additional Interest will cease to
accrue and, if such Event of Default has not been cured or waived prior to such 181st day, the payment of the principal of the Securities may be accelerated by the Holders or the Trustee as provided above. 

In order to elect to pay Additional Interest as the sole remedy during the first 180 days after the occurrence of any Event of Default
relating to the failure to comply with the obligations under Section 4.03(a) or for any failure to comply with the requirements of Section 314(a)(1) of the TIA (at any time such section is applicable to this Indenture, if any), the Company
shall notify all Holders and the Trustee and the Paying Agent of such election in writing prior to the Close of Business on the date that is one Business Day following the date on which such Event of Default occurs (which will be the 61st day after
written notice is provided to the Company of the Default pursuant to the last paragraph of Section 6.01, unless such failure is cured or waived prior to such 61st day). If the Company fails to give timely notice of such election, the Securities
will be immediately subject to acceleration as provided in Section 6.02(a). 
 In the event the Company does not elect to pay
Additional Interest upon such Event of Default in accordance with this Section 6.02(b), the Securities will be subject to acceleration as provided in Section 6.02(a). This Section 6.02(b) does not affect the rights of Holders if any
other Event of Default occurs under this Indenture. 

  
 37 

 Additional Interest shall be payable at the same time, in the same manner and to the same Persons
as ordinary interest. Any Additional Interest that is payable in accordance with this Section 6.02(b) shall, subject to the immediately succeeding sentence, be in addition to, and not in lieu of, any Additional Interest that is payable pursuant
to Section 4.03(d) and Section 4.03(e). However, in no event will the rate of any such Additional Interest payable pursuant to this Section 6.02(b), when taken together with any Additional Interest that may accrue as a result of the
Company’s failure to timely file any document or report that it is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other
than reports on Form 8-K), as described under Section 4.03(d), accrue at a rate in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest. 

(c) If the Company is required to pay Additional Interest to Holders, the Company shall provide a direction or order in the form of a written
notice to the Trustee (and if the Trustee is not the Paying Agent, to the Paying Agent) of the Company’s obligation to pay such Additional Interest no later than three Business Days prior to the date on which any such Additional Interest is
scheduled to be paid. Such notice shall set forth the amount of Additional Interest to be paid by the Company on such payment date and direct the Trustee (or, if the Trustee is not the Paying Agent, to the Paying Agent) to make payment to the extent
it receives funds from the Company to do so. The Trustee shall not at any time be under any duty or responsibility to any Holder to determine whether the Additional Interest is payable, or with respect to the nature, extent or calculation of the
amount of the Additional Interest owed, or with respect to the method employed in such calculation of the Additional Interest. 

Section 6.03. Other Remedies. Notwithstanding any other provision of this Indenture, if an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of amounts due with respect to the Securities or to enforce the performance of any provision of the Securities or this Indenture. 

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A
delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative.

 In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to
which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Securities, and it shall not be necessary to make any Holders of the Securities parties to any such proceedings. 

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or
abandoned because of any waiver pursuant hereto or any rescission and annulment pursuant hereto or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders and the Trustee
shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders and the Trustee shall continue as though no such
proceeding had been instituted. 

  
 38 

 Section 6.04. Waiver of Past Defaults. Subject to Section 6.07 and
Section 9.02, the Holders of a majority in aggregate principal amount of the Securities then outstanding may on behalf of all Holders of Securities, by written notice to the Trustee, waive any past Default or Event of Default and its
consequences, other than a Default or Event of Default (a) in the payment of the principal of, or interest on, any Security, or in the payment of the Fundamental Change Repurchase Price or the Redemption Price, as the case may be,
(b) arising from a failure by the Company to convert any Securities in accordance with this Indenture or (c) in respect of any provision of this Indenture or the Securities which, under Section 9.02, cannot be modified or amended
without the consent of the Holder of each outstanding Security affected, if: 
 (i) all existing Defaults or Events of
Default, other than the nonpayment of the principal of and interest on the Securities that have become due solely by the declaration of acceleration, have been cured or waived; and 

(ii) the waiver would not conflict with any judgment or decree of a court of competent jurisdiction. 

When a Default or an Event of Default is waived, it is cured and ceases to exist for all purposes under this Indenture, but no such waiver
will extend to any subsequent or other Default or Event of Default or impair any rights of Holders or the Trustee related thereto. 

Section 6.05. Control by Majority. The Holders of a majority in aggregate principal amount of the Securities then outstanding
shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it with respect to the Securities. However, the Trustee may refuse to follow
any direction that conflicts with law or this Indenture, is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it; provided that the
Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. 
 Section 6.06.
Limitation on Suits. Except with respect to any proceeding instituted in accordance with Section 6.07, a Holder shall not have any right to institute any suit, action or proceeding in equity or at law upon or under or with respect to
this Indenture, or for the appointment of a receiver or a trustee, or for any other remedy under this Indenture unless: 
 (a) such Holder
previously shall have given the Trustee written notice of a continuing Event of Default; 
 (b) the Holders of at least twenty five percent
(25%) in aggregate principal amount of the Securities then outstanding shall have made a written request to the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; 

  
 39 

 (c) such Holder or Holders shall have offered and if requested, provided to the Trustee indemnity
satisfactory to the Trustee against any loss, liability or expense to or of the Trustee in connection with pursuing such remedy; and 
 (d)
the Trustee shall have failed to comply with the request for sixty (60) days after receipt of such notice, request and offer of indemnity, and during such sixty (60) day period, the Holders of a majority in aggregate principal amount of
the Securities then outstanding have not given the Trustee a direction that is inconsistent with the request. 
 A Holder may not use this
Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly
prejudicial to such Holders). A Holder shall have the right to not enforce any right under this Indenture except in the manner herein. 

Section 6.07. Rights of Holders to Receive Payment and to Convert Securities. Notwithstanding any other provision of this
Indenture, the right of any Holder to receive payment of all amounts (including any principal, interest or the Fundamental Change Repurchase Price or the Redemption Price) due with respect to the Securities, on or after the respective due dates as
provided herein, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of the Holder. 

In addition, notwithstanding any other provision of this Indenture, the right of any Holder to convert a Security in accordance with this
Indenture, or to bring suit for the enforcement of such right, shall not be impaired or affected without the consent of the Holder. 

Section 6.08. Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a) or Section 6.01(b) has
occurred and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount due with respect to the Securities, including any unpaid and accrued interest. 

Section 6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee, any predecessor Trustee and the Holders allowed in any judicial proceedings relative to the Company or its creditors or properties. 

The Trustee may collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same, and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making
of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.06. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

  
 40 

 Section 6.10. Priorities. If the Trustee collects any money pursuant to this Article
6, it shall pay out the money in the following order: 
  

			
	First:	  	to the Trustee for amounts due under Section 7.06;
		
	Second:	  	to Holders for all amounts due and unpaid on the Securities, without preference or priority of any kind, according to the amounts due and payable on the Securities; and
		
	Third:	  	the balance, if any, to the Company.

 The Trustee, upon prior written notice to the Company, may fix a record date and payment date for any payment
by it to Holders pursuant to this Section 6.10. At least fifteen (15) days before each such record date, the Trustee shall send to each Holder and the Company a written notice that states such record date and payment date and the amount of
such payment. 
 Section 6.11. Remedies Cumulative and Continuing. All powers and remedies given by this Article 6 to the
Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Securities, by judicial proceedings or
otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder of any of the Securities to exercise any right or power accruing upon any
Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions of Section 6.06, every power and remedy
given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders. 

Section 6.12. Notice of Defaults. The Trustee shall, within 90 days after the occurrence and continuance of a Default of which a
Responsible Officer has received written notice of, mail or transmit to all Holders, as the names and addresses of such Holders appear upon the security register of the Registrar, notice of all Defaults known to a Responsible Officer, unless such
Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a Default in the payment of the principal of (including the Redemption Price and the Fundamental Change Repurchase Price, if
applicable), or accrued and unpaid interest on, any of the Securities or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as a committee of
Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders. 

Section 6.13. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit
against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit other 

  
 41 

 
than the Trustee of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant
in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, a suit by a Holder or
group of Holders of more than ten percent (10%) in aggregate principal amount of the outstanding Securities, any suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any
Security (including, but not limited to, the Redemption Price and the Fundamental Change Repurchase Price, if applicable) on or after the due date expressed or provided for in such Security or any suit for the enforcement of the right to convert any
Security, or receive the consideration due upon conversion, in accordance with the provisions of Article 10. 
 ARTICLE 7 

TRUSTEE 

Section 7.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such
of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent Person would exercise or use under the circumstances in the conduct of his or her own affairs. 

(b) Except during the continuance of an Event of Default: 

(i) the Trustee need perform only those duties that are specifically set forth in this Indenture and no implied covenants or
obligations shall be read into this Indenture against the Trustee; and 
 (ii) in the absence of bad faith on its part, the
Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of
any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this
Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). 
 (c) The Trustee
may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: 

(i) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved
that the Trustee was negligent in ascertaining the pertinent facts; and 
 (ii) the Trustee shall not be liable with respect
to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05. 

  
 42 

 (d) Every provision of this Indenture that in any way relates to the Trustee is subject to the
provisions of this Section 7.01.

performance of any of its duties hereunder, or in the exercise of any of its rights or powers. 
 Section 7.02. Rights of
Trustee. (a) The Trustee may conclusively rely on any document believed by it in good faith to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document;
if, however, the Trustee shall determine to make such further inquiry or investigation, it shall be entitled during normal business hours to examine the relevant books, records and premises of the Company, personally or by agent or attorney upon
reasonable prior notice, at the sole cost of the Company, and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. 

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate and/or an Opinion of Counsel. The Trustee
shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. 

(c) Any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Order, and any resolution of the
Board of Directors shall be sufficiently evidenced by a Board Resolution.

(e) The Trustee may act through agents or attorneys and shall not be responsible for the misconduct or negligence of any agent or attorney
appointed with due care. 
 (f) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to

of the Company with respect to the covenants contained in Article 4. In addition, the Trustee shall not be deemed to have knowledge of an Event of Default except (i) any Default or Event of Default occurring

  
 43 

 
pursuant to Section 6.01(a) or (b) for which it acts as Paying Agent or (ii) any Default or Event of Default of which a Responsible Officer shall have received written notification
or obtained actual knowledge. Delivery of reports, information and documents to the Trustee under Article 4 (other than Section 4.04 and 4.06) is for informational purposes only and the Trustee’s receipt of the foregoing shall not
constitute actual or constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to
rely on Officers’ Certificates). 
 (h) The Trustee shall be under no obligation to exercise any of the rights or powers vested by this
Indenture at the request or demand of any of the Holders pursuant to this Indenture unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be
incurred by it in compliance with such request or demand. 
 (i) The rights, privileges, protections, immunities and benefits given to the
Trustee, including without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each Securities Agent, agent, custodian and other Person employed to act
hereunder. 
 (j) The Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of
Officers authorized at such time to take specified actions pursuant to this Indenture, which certificate may be signed by any Person authorized to sign an Officers’ Certificate, including any Person specified as so authorized in any such
certificate previously delivered and not superseded.

the Trustee or any Securities Agent be liable under or in connection with this Indenture and the Securities for indirect, special, incidental, punitive or consequential losses or damages of any kind whatsoever, including but not limited to lost
profits, whether or not foreseeable, even if the Trustee or such Securities Agent has been advised of the possibility thereof and regardless of the form of action in which such damages are sought. 

(l) No bond or surety shall be required of the Trustee with respect to performance of the Trustee’s duties and powers hereunder. 

(m) Under no circumstances shall the Trustee be liable in its individual capacity for the obligations evidenced by this Indenture or the Note.

 (n) Any discretion, permissive right, or privilege of the Trustee hereunder shall not be deemed to be or otherwise construed as a duty or
obligation of the Trustee hereunder. 
 (o) In no event shall the Trustee be responsible or liable for any special, indirect, punitive,
incidental or consequential damages or losses of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

  
 44 

 Section 7.03. Individual Rights of Trustee. The Trustee in its individual or any
other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or any of its Affiliates with the same rights the Trustee would have if it were not Trustee. Any Securities Agent may do the same with like rights.
The Trustee, however, must comply with Section 7.09. 
 Section 7.04. Trustee’s Disclaimer. The Trustee makes no
representation as to the validity or adequacy of this Indenture or the Securities; the Trustee shall not be accountable for the Company’s use of the proceeds from the Securities; and the Trustee shall not be responsible for any statement in the
Securities other than its certificate of authentication. 
 Section 7.05. Notice of Defaults. If a Default or Event of Default
occurs and is continuing as to which the Trustee is deemed to have knowledge in accordance with Section 7.02(g), then the Trustee shall send to each Holder a notice of the Default or Event of Default within thirty (30) days after receipt
of such notice or after acquiring such knowledge, as applicable, unless such Default or Event of Default has been cured or waived; provided, however, that, except in the case of a Default or Event of Default in payment or delivery of
any amounts due (including principal, interest, the Fundamental Change Repurchase Price, the Redemption Price or the consideration due upon conversion) with respect to any Security, the Trustee may withhold such notice if, and so long as it in good
faith determines that, withholding such notice is in the best interests of Holders. 
 Section 7.06. Compensation and Indemnity.
The Company shall pay to the Trustee from time to time such compensation for its services hereunder as shall be mutually agreed upon in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred by it pursuant to, and in accordance with, any provision hereof, except for any such expenses as shall have been caused by the
Trustee’s own negligence or willful misconduct. Such expenses shall include the reasonable compensation and out-of-pocket expenses of the Trustee’s agents and counsel. The Trustee shall provide the Company with reasonable notice of any
expense not in the ordinary course of business. 
 The Company shall indemnify each of the Trustee, each predecessor Trustee and their
respective agents for, and hold each of them harmless against, any and all loss, liability, damage, claim, cost or expense (including the reasonable fees and expenses of counsel and taxes other than those based upon the income of the Trustee)
incurred by it in connection with the acceptance or administration of this trust, the performance of its duties and/or the exercise of its rights hereunder, or in connection with enforcing the provisions of this Section 7.06, including the
reasonable costs and expenses of defending itself against any claim (whether asserted by the Company, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers and duties hereunder. The Company
need not pay for any settlement made without its consent. The Trustee shall notify the Company promptly of any claim for which it may seek indemnification; provided that failure to give such notice shall not relieve the Company of its
obligations under this Section 7.06. The Company need not reimburse any expense or indemnify against any loss or liability incurred by the Trustee through the Trustee’s own negligence or willful misconduct. 

  
 45 

 To secure the Company’s payment obligations in this Section 7.06, the Trustee shall
have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay amounts due on particular Securities. 

The indemnity obligations of the Company with respect to the Trustee provided for in this Section 7.06 shall survive any resignation or
removal of the Trustee and any termination of this Indenture. 
 When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(h) or Section 6.01(i) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. 

Section 7.07. Replacement of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become
effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.07. 
 The Trustee may resign
by so notifying the Company in writing thirty (30) days prior to such resignation. The Holders of a majority in aggregate principal amount of the Securities then outstanding may remove the Trustee by so notifying the Trustee and the Company in
writing and may appoint a successor Trustee with the Company’s consent. The Company may remove the Trustee if: 
 (a) the Trustee fails
to comply with Section 7.09; 
 (b) the Trustee is adjudged a bankrupt or an insolvent; 

(c) a receiver or other public officer takes charge of the Trustee or its property; or 

(d) the Trustee becomes incapable of acting. 

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee. 
 If a successor Trustee does not take office within thirty (30) days after the retiring Trustee resigns or is
removed, the retiring Trustee (at the Company’s expense), the Company or the Holders of at least ten percent (10%) in aggregate principal amount of the outstanding Securities may petition any court of competent jurisdiction for the
appointment of a successor Trustee. 
 If the Trustee fails to comply with Section 7.09, the Company or any Holder may petition any
court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 A successor Trustee shall
deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties
of the Trustee under this Indenture. The successor Trustee shall send a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for
in Section 7.06. 

  
 46 

 Section 7.08. Successor Trustee by Merger, Etc. If the Trustee consolidates with,
merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee, if such successor corporation is otherwise
eligible hereunder. 
 Section 7.09. Eligibility; Disqualification. There shall at all times be a Trustee hereunder that
(i) is an entity organized and doing business under the laws of the United States of America or of any state thereof or the District of Columbia, (ii) is subject to supervision or examination by federal or state authorities and
(iii) has a combined capital and surplus of at least $50 million as set forth in its most recent published annual report of condition. 

Section 7.10. Preferential Collection of Claims Against Company. To the extent the TIA then applies to the Indenture, the
Trustee is subject to TIA §311(a), excluding any creditor relationship listed in TIA §311(b). To the extent the TIA then applies to the Indenture, a Trustee who has resigned or been removed shall be subject to §311(a) to the extent
indicated. 
 Section 7.11. Reports by Trustee to Holders. Within 60 days after each May 15, beginning with May 15,
2016, the Trustee shall send to all Holders of the Securities, as their names and addresses appear on the register kept by the Registrar, a brief report dated as of such date, in accordance with, and to the extent required under, TIA § 313(a)
(but if no event described in TIA §313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also will comply with TIA § 313(b)(2). The Trustee will also send all reports as
required by TIA § 313(c). A copy of each report at the time of its delivery to the Holders of Securities shall be delivered to the Company and each stock exchange on which the Securities are listed in accordance with TIA § 313(d). The
Company shall promptly notify the Trustee in writing when the Securities are listed on any stock exchange or any delisting thereof. 

ARTICLE 8 
 DISCHARGE OF
INDENTURE 
 Section 8.01. Termination of the Obligations of the Company. This Indenture shall cease to be of further
effect, and the Trustee shall execute instruments acknowledging satisfaction and discharge of this Indenture, if: (a) either (i) all outstanding Securities (other than Securities replaced pursuant to Section 2.07) have been delivered
to the Trustee for cancellation or (ii) all outstanding Securities have become due and payable at their scheduled maturity or upon conversion, Repurchase Upon Fundamental Change or redemption, and in either case the Company irrevocably
deposits, prior to the applicable due date, with the Trustee or the Paying Agent (if the Paying Agent is not the Company or any of its Affiliates) cash (or, in the case of conversion, delivers to the Holders in accordance with Article 10 cash,
Common Stock (and cash in lieu of any fractional shares) or a combination thereof, as applicable, solely to satisfy the Company’s Conversion Obligation) sufficient to satisfy all obligations due and owing on all outstanding Securities (other
than Securities replaced pursuant to Section 2.07) on the Maturity 

  
 47 

 
Date, the relevant settlement date of any conversion, the Fundamental Change Repurchase Date or the Redemption Date, as the case may be; (b) the Company pays to the Trustee all other sums
payable hereunder by the Company; and (c) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for herein relating to the satisfaction and
discharge of this Indenture have been complied with; provided, however, that Section 2.03, Section 2.04, Section 2.05, Section 2.08, Section 7.06, Section 7.07, Section 7.08, Section 7.09,
Section 14.09, Section 14.14 and this Article 8 shall survive any discharge of this Indenture until such time as all payments in respect of the Securities have been paid in full and there are no Securities outstanding; provided
further, however, that Section 7.06 shall also survive after the Securities are paid in full and there are no Securities outstanding. 

Section 8.02. Application of Trust Money. The Trustee shall hold in trust all money deposited with it pursuant to
Section 8.01 and shall apply such deposited money through the Paying Agent and in accordance with this Indenture to the payment of amounts due on the Securities. 

Section 8.03. Repayment to Company. 

Subject to applicable escheatment laws, the Trustee and the Paying Agent shall promptly notify the Company of, and pay to the Company upon the
written request of the Company, any excess money held by them at any time. The Trustee or the Paying Agent, as the case may be, shall provide written notice to the Company of any money that has been held by it and has, for a period of two
(2) years, remained unclaimed for the payment of the principal of, or any accrued and unpaid interest on, the Securities. Subject to the requirements of applicable law, the Trustee and the Paying Agent shall pay to the Company upon the written
request of the Company any money held by them for the payment of the principal of, or any accrued and unpaid interest on, the Securities that remains unclaimed for two (2) years. After payment to the Company, Holders entitled to the money must
look to the Company for payment as general creditors, subject to applicable law, and all liability of the Trustee and the Paying Agent with respect to such money and payment shall, subject to applicable law, cease. 

Section 8.04. Reinstatement. If any money, Common Stock or other consideration cannot be applied in accordance with
Section 8.01 and 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, the obligations of the Company
under this Indenture and the Securities shall be revived and reinstated as though no deposit or delivery had occurred pursuant to Section 8.01 and Section 8.02 until such time as the Trustee or Paying Agent is permitted to apply all such
money in accordance with Section 8.01 and Section 8.02; provided, however, that if the Company has made any payment of amounts due with respect to any Securities because of the reinstatement of its obligations, then the
Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money, Common Stock or other consideration held by the Trustee or Paying Agent. 

  
 48 

 ARTICLE 9 

AMENDMENTS 

Section 9.01. Without Consent of Holders. The Company and the Trustee may amend or supplement this Indenture or the Securities
without notice to or the consent of any Holder: 
 (a) to comply with Section 5.01 or Section 10.11; 

(b) to secure the obligations of the Company in respect of the Securities or add guarantees with respect to the Securities; 

(c) to evidence and provide for the appointment of a successor Trustee in accordance with Section 7.07; 

(d) to comply with the provisions of any securities depository, including DTC, clearing agency, clearing corporation or clearing system, or
the requirements of the Trustee or the Registrar, relating to transfers and exchanges of any applicable Securities pursuant to this Indenture; 

(e) to add to the covenants or Events of Default of the Company described in this Indenture for the benefit of Holders or to surrender any
right or power conferred upon the Company; 
 (f) to make provision with respect to adjustments to the Conversion Rate as required by this
Indenture or to increase the Conversion Rate in accordance with this Indenture; 
 (g) to irrevocably elect or eliminate one or more
Settlement Methods and/or irrevocably elect a minimum Specified Dollar Amount; 
 (h) to make any change that does not adversely affect the
rights of any Holder; 
 (i) to permit the conversion of the Securities into Reference Property in accordance with Section 10.11; or

 (j) to comply with the requirement of the SEC in order to effect or maintain the qualification of this Indenture and any supplemental
indenture under the TIA. 
 In addition, the Company and the Trustee may enter into a supplemental indenture without the consent of Holders
of the Securities to cure any ambiguity, defect, omission or inconsistency in this Indenture in a manner that does not materially adversely affect the rights of any Holder. 

Any supplemental indenture authorized by the provisions of this Section 9.01 may be executed by the Company and the Trustee without the
consent of the Holders of any of the Securities at the time outstanding, notwithstanding any of the provisions of Section 9.02. 

  
 49 

 Section 9.02. With Consent of Holders. The Company and the Trustee may amend or
supplement this Indenture or the Securities with the written consent of the Holders of at least a majority in aggregate principal amount of the outstanding Securities (including, without limitation, consents obtained from Holders in connection with
a purchase of, or tender or exchange offer for, Securities). Subject to Section 6.04 and 6.07, the Holders of a majority in aggregate principal amount of the outstanding Securities may, by written notice to the Trustee, waive by consent
(including, without limitation, consents obtained from Holders in connection with a purchase of, or tender or exchange offer for, Securities) compliance by the Company with any provision of this Indenture or the Securities without notice to any
other Holder. Notwithstanding the foregoing or anything herein to the contrary, without the consent of the Holder of each outstanding Security affected, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may not:

 (a) change the stated maturity of the principal of, or the payment date of any installment of interest on, any Security; 

(b) reduce the principal amount of any Security, or any interest on, any Security or alter or waive the provisions with respect to the
redemption of such Security; 
 (c) change the place or currency of payment of principal of, or any interest on, any Security; 

(d) impair the right of any Holder to receive any payment on, or with respect to, or any delivery or payment due upon the conversion of, any
Security or impair the right to institute suit for the enforcement of any delivery or payment on, or with respect to, or due upon the conversion of, any Security; 

(e) modify, in a manner adverse to Holders, the obligation of the Company pursuant to Section 3.01 to repurchase Securities upon the
occurrence of a Fundamental Change; 
 (f) adversely affect the right of Holders to convert Securities in accordance with Article 10; 

(g) reduce the percentage in aggregate principal amount of outstanding Securities whose Holders must consent to a modification to or amendment
of any provision of this Indenture or the Securities; or 
 (h) modify the provisions of Article 9 that require each Holder’s consent
or the waiver provisions of Section 6.04 with respect to modification and waiver (including waiver of a Default or an Event of Default), except to increase the percentage required for modification or waiver or to provide for the consent of each
affected Holder. 
 Notwithstanding the foregoing or anything to the contrary, so long as any Atairos Securities are outstanding, without
the consent of the Holders of 100% of the aggregate principal amount of the Atairos Securities, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may not modify any provision contained in this Indenture
specifically and uniquely applicable to the Atairos Securities in a manner adverse to the Holders of, or the holders of a beneficial interest in, the Atairos Securities. 

  
 50 

 Promptly after an amendment, supplement or waiver under Section 9.01 or this
Section 9.02 becomes effective, the Company shall send, or cause to be sent, to Holders a notice briefly describing such amendment, supplement or waiver. Any failure of the Company to send such notice shall not in any way impair or affect the
validity of such amendment, supplement or waiver. 
 It shall not be necessary for the consent of the Holders under this Section 9.02
to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 

Section 9.03. Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective (or until such earlier
date as specified by the Company in connection with the solicitation of such consent), a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt
as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the
notice of revocation before the date the amendment, supplement or waiver becomes effective (or such earlier date specified by the Company in connection with the solicitation of such consent). 

After an amendment, supplement or waiver becomes effective with respect to the Securities, it shall bind every Holder unless such amendment,
supplement or waiver makes a change that requires, pursuant to Section 9.02, the consent of each Holder affected. In that case, the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and every
subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security. Any amendment to this Indenture or the Securities shall be set forth in a supplemental indenture to this Indenture that
complies with the TIA as then in effect, if the TIA is applicable to this Indenture. 
 Nothing in this Section 9.03 shall impair the
Company’s rights pursuant to Section 9.01 to amend this Indenture or the Securities without the consent of any Holder in the manner set forth in, and permitted by, such Section 9.01. 

Section 9.04. Notation on or Exchange of Securities. If an amendment, supplement or waiver changes the terms of a Security,
the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security as directed and prepared by the Company about the changed terms and return it to the Holder.
Alternatively, if the Company so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. 

Section 9.05. Trustee Protected. The Trustee shall sign any amendment, supplemental indenture or waiver authorized pursuant to
this Article 9; provided, however, that the Trustee need not sign any amendment, supplement or waiver authorized pursuant to this Article 9 that 

  
 51 

 
adversely affects the Trustee’s rights, duties, liabilities or immunities. The Trustee shall be entitled to receive and conclusively rely upon, in addition to the documents set forth in
Section 14.03, an Opinion of Counsel as to legal matters and an Officers’ Certificate as to factual matters each stating that any supplemental indenture, amendment or waiver is permitted or authorized pursuant to this Indenture and
constitutes the legal, valid and binding obligation of the Company enforceable in accordance with its terms (subject to customary exceptions). 

Section 9.06. Effect of Supplemental Indentures. Upon the due execution and delivery of any supplemental indenture in accordance
with this Article 9, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes, and, except as set forth in Section 9.02 and Section 9.03, every Holder of
Securities shall be bound thereby. 
 ARTICLE 10 

CONVERSION 

Section 10.01. Conversion Privilege. (a) Subject to the limitations of Section 10.02, Section 10.11 and the
settlement provisions of Section 10.14(c), and upon compliance with the provisions of this Article 10, each Holder of a Security shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted
is $1,000 principal amount or a multiple thereof) of such Security at any time prior to the Close of Business on the Scheduled Trading Day immediately preceding the Maturity Date, in each case, at the then applicable Conversion Rate per $1,000
principal amount of Securities (subject to the settlement provisions of Section 10.02, the “Conversion Obligation”). 

(b) To convert its Security, a Holder of a Physical Security must (i) complete and manually sign the Conversion Notice, with appropriate
notarization or signature guarantee, or facsimile of the Conversion Notice and deliver the completed Conversion Notice or facsimile thereof to the Conversion Agent, (ii) surrender the Security to the Conversion Agent, (iii) furnish
appropriate endorsements and transfer documents if required by the Registrar or Conversion Agent, (iv) pay all transfer or similar taxes if required pursuant to Section 10.04 and (v) pay funds equal to interest payable on the next
Interest Payment Date if so required by Section 10.02(d). If a Holder holds a beneficial interest in a Global Security, to convert such Security, the Holder must comply with clauses (iv) and (v) above and the Depository’s
procedures for converting a beneficial interest in a Global Security. 
 (c) A Holder may convert a portion of the principal amount of a
Security if such portion is $1,000 principal amount or an integral multiple of $1,000 principal amount in excess thereof. Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of such
Security. 
 Section 10.02. Conversion Procedure and Payment Upon Conversion. 

(a) Subject to this Section 10.02 and Section 10.11 and the settlement provisions of Section 10.14(c), upon conversion of any
Security, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Securities 

  
 52 

 
being converted, cash (“Cash Settlement”), Common Stock, together with cash, if applicable, in lieu of delivering any fractional shares of Common Stock in accordance with
Section 10.03 (“Physical Settlement”) or a combination of cash and Common Stock, together with cash, if applicable, in lieu of delivering any fractional shares of Common Stock in accordance with Section 10.03
(“Combination Settlement”), at its election, as set forth in this Section 10.02. 
 (i) All conversions
for which the relevant Conversion Date occurs on or after the 22nd Scheduled Trading Day immediately preceding the Maturity Date, and all conversions for which the relevant Conversion Date occurs after the Company’s issuance of a notice of
redemption with respect to the Securities and prior to the related Redemption Date, shall be settled using the same Settlement Method. 

(ii) The Company shall use the same Settlement Method for all conversions of Securities occurring on the same Conversion Date
(except for any conversions described in the immediately preceding clause (i)), but the Company shall not have any obligation to use the same Settlement Method with respect to conversions that occur on different Conversion Dates. 

(iii) If, in respect of any Conversion Date (or for all conversions in any period), the Company elects to deliver a notice (the
“Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company, through the Trustee, shall deliver such Settlement Notice to converting Holders no later
than the Close of Business on the Trading Day immediately following the relevant Conversion Date to which such Settlement Notice applies (or, in the case of any conversions for which the relevant Conversion Date occurs (x) after the date of
issuance of a notice of redemption and prior to the related Redemption Date, in such notice of redemption or (y) on or after the 22nd Scheduled Trading Day immediately preceding the Maturity Date, no later than the 22nd Scheduled Trading Day
immediately preceding the Maturity Date). If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence for a Conversion Date, the Company shall no longer have the right to elect Cash
Settlement or Physical Settlement with respect to conversions on such Conversion Date and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation on such Conversion Date, and the Specified Dollar
Amount per $1,000 principal amount of Securities shall be equal to $1,000. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate
the Specified Dollar Amount per $1,000 principal amount of Securities. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000
principal amount of Securities in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Securities shall be deemed to be $1,000. Notwithstanding the foregoing, any conversion of Atairos Securities shall be subject to
Section 10.02(a)(v). 

  
 53 

 (iv) The cash, Common Stock or combination of cash and Common Stock in respect of
any conversion of Securities (the “Settlement Amount”) shall be computed as follows: 
 (A) if the Company
elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder in respect of each $1,000 principal amount of Securities being converted a number of shares of
Common Stock equal to the Conversion Rate in effect on the Conversion Date (provided that the Company shall deliver cash in lieu of any fractional shares as described in Section 10.03); 

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company
shall pay to the converting Holder in respect of each $1,000 principal amount of Securities being converted cash in an amount equal to the sum of the Daily Conversion Values for each Trading Day during the related Observation Period; and 

(C) if the Company elects (or is deemed to have elected pursuant to Section 10.02(a)(iii)) to satisfy its Conversion
Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver to the converting Holder, as the case may be, in respect of each $1,000 principal amount of Securities being converted, a Settlement Amount equal to
the sum of the Daily Settlement Amounts for each Trading Day during the related Observation Period. 
 (v) Notwithstanding
anything herein to the contrary, the Company hereby initially elects to satisfy its Conversion Obligation with respect to any conversion of Atairos Securities by Combination Settlement with a Specified Dollar Amount of $1,000 per $1,000 principal
amount of Securities. The Company may change its Settlement Method election (and, in the case of Combination Settlement, the Specified Dollar Amount) with respect to any conversion of Atairos Securities by delivering a notice that specifies the
newly elected Settlement Method and, in the case of Combination Settlement, the applicable Specified Dollar Amount (the “Atairos Settlement Notice”) to the Holders of the Atairos Securities, and such newly elected Settlement Method
(and, in the case of Combination Settlement, the Specified Dollar Amount) shall be effective no earlier than ten (10) Trading Days after the date on which such Atairos Settlement Notice was received by the Holder. In the event any Holder(s) of
Atairos Securities exercises its right to convert all or any portion of such Atairos Securities, (A) the relevant Observation Period for purposes of determining the Daily Settlement Amount, in the case of Combination Settlement, and Daily
Conversion Values, in the case of Cash Settlement, with respect to such Atairos Securities shall be the 20 consecutive Trading Day period beginning on, and including, the 20th Trading Day immediately preceding the applicable Conversion Date and
ending on the Trading Day immediately preceding such Conversion Date and (B) the Company shall promptly (x) determine the Daily Settlement Amount or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of
delivering any fractional shares of Common Stock and (y) notify the Trustee, the Conversion Agent (if other than the Trustee) and such Holder 

  
 54 

 
of Atairos Securities being so converted of the Daily Settlement Amount or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering any fractional
shares of Common Stock. 
 (vi) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable)
shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in
lieu of delivering any fractional shares of Common Stock, and in any event within one (1) Business Day following the last day of the Observation Period, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee)
of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have
no responsibility for any such determination. 
 (b) Each conversion shall be deemed to have been effected as to any Securities surrendered
for conversion at the Close of Business on the applicable Conversion Date; provided, however, that the Person in whose name any shares of the Common Stock shall be issuable upon such conversion shall become the holder of record of such
shares as of the Close of Business on such Conversion Date (in the case of Physical Settlement or any conversion of Atairos Securities) or the last Trading Day of the relevant Observation Period (in the case of Combination Settlement of Securities
other than Atairos Securities). Prior to such time, a Holder receiving Common Stock upon conversion shall not be entitled to any rights relating to such Common Stock, including, among other things, the right to vote and receive dividends and notices
of shareholder meetings. The Company will determine the Conversion Date and the last Trading Day of the relevant Observation Period, as applicable, in accordance with the requirements set forth herein and notify the Trustee of the same. 

(c) In the case of any conversion of Securities other than the Atairos Securities, the Company shall pay or deliver, as the case may be, the
consideration due in respect of the Conversion Obligation on the later of (i) the third Business Day immediately following the relevant Conversion Date (in the case of Physical Settlement) and (ii) the third Business Day immediately
following the last Trading Day of the relevant Observation Period (in the case of Combination Settlement or Cash Settlement). In the case of any conversion of Atairos Securities, (i) to the extent all or a portion of the Conversion Obligation
is paid in cash, such cash shall not be due until the earlier of (A) the 30th Business Day immediately following the relevant Conversion Date and (B) the Maturity Date, and (ii) to the extent all or a portion of the Conversion
Obligation is to be paid in shares of Common Stock, such shares shall be delivered on the day specified in a written notice from the beneficial owner(s) of the Atairos Securities being converted that is delivered to the Company on or prior to the
second Business Day immediately following the relevant Conversion Date, which delivery date (in respect of such shares of Common Stock) shall be no earlier than the third Business Day immediately following the relevant Conversion Date and be no
later than the seventh Business Day immediately following the relevant Conversion Date (it being understood that if no such notice is delivered to the Company, then the Company shall deliver such shares on the third Business

  
 55 

 
Day immediately following the relevant Conversion Date). Such written notice shall include a certification therein that the beneficial owners delivering such written notice are holders that hold
beneficial interests in the Atairos Securities subject to conversion. If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and deliver or cause to be delivered to such Holder, or such
Holder’s nominee(s) or transferee(s), certificates or a book-entry transfer through the Depository for the full number of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation. 

(d) Except to the extent otherwise provided in this Section 10.02(d), no payment or adjustment will be made for accrued interest on a
converted Security, and accrued interest, if any, will be deemed to be paid by the consideration paid to the Holder upon conversion. Such accrued interest, if any, shall be deemed to be paid in full rather than cancelled, extinguished or forfeited.
The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Security and accrued and unpaid interest, if any, to, but not including, the relevant Conversion
Date. Upon a conversion of Securities into a combination of cash and Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. If any Holder surrenders a Security for conversion after the
Close of Business on the Record Date for the payment of an installment of interest but prior to the Open of Business on the next Interest Payment Date, then, notwithstanding such conversion, the full amount of interest payable with respect to such
Security on such Interest Payment Date shall be paid on such Interest Payment Date to the Holder of record of such Security at the Close of Business on such Record Date; provided, however, that such Security, when surrendered for
conversion, must be accompanied by payment in cash to the Conversion Agent on behalf of the Company of an amount equal to the full amount of interest payable on such Interest Payment Date on the Security so converted; provided further,
however, that such payment to the Conversion Agent described in the immediately preceding proviso in respect of a Security surrendered for conversion shall not be required with respect to a Security that (i) is surrendered for conversion
after the Close of Business on the Record Date immediately preceding the Maturity Date, (ii) is surrendered for conversion after the Close of Business on a Record Date for the payment of an installment of interest and on or prior to the Open of
Business on the related Interest Payment Date, where, pursuant to Section 3.01, the Company has specified, with respect to a Fundamental Change, a Fundamental Change Repurchase Date that is after such Record Date but on or prior to such
Interest Payment Date or (iii) is surrendered for conversion after the Close of Business on a Record Date for the payment of an installment of interest and on or prior to the Open of Business on the related Interest Payment Date, where,
pursuant to Section 13.01, the Company has specified a Redemption Date that is after such Record Date but on or prior to such Interest Payment Date. 

(e) If a Holder converts more than one Security at the same time, the Conversion Obligation with respect to such Securities shall be based on
the total principal amount of all Securities so converted. 

  
 56 

 (f) Upon surrender of a Security that is converted in part, the Trustee shall authenticate for
the Holder a new Security equal in principal amount to the unconverted portion of the Security surrendered. 
 Section 10.03. Cash
in Lieu of Fractional Shares. The Company shall not issue fractional shares of Common Stock upon the conversion of a Security. Instead, the Company shall pay to converting Holders cash in lieu of fractional shares based on the Daily VWAP on the
relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP on the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). If more than one Security shall be surrendered for
conversion at one time by the same Holder, the number of full shares that shall be issuable upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period (in the case of
Combination Settlement) or the aggregate principal amount of the Securities, or specified portions thereof to the extent permitted hereby (in the case of Physical Settlement) so surrendered, and any fractional shares remaining after such computation
shall be paid in cash. 
 Section 10.04. Taxes on Conversion. If a Holder converts its Security, the Company shall pay any
documentary, stamp or similar issue or transfer tax or duty due on the issue, if any, of Common Stock upon the conversion. However, the Holder shall pay such tax which is due because the Holder requests the shares of Common Stock to be issued in a
name other than the Holder’s name. The Company may refuse to deliver the certificate(s) representing the Common Stock being issued or delivered to the Holder or in a name other than such Holder’s name until the Conversion Agent receives a
sum sufficient to pay any tax or duty which will be due because shares of Common Stock are to be issued or delivered in a name other than such Holder’s name. 

Section 10.05. Company to Provide Common Stock. The Company shall at all times reserve and keep available, free from preemptive
rights, out of its authorized but unissued stock, for the purpose of effecting the conversion of the Securities, such number of its duly authorized shares of Common Stock as shall from time to time be sufficient for the conversion of all outstanding
Securities into shares of Common Stock at any time (assuming, for such purposes, that (i) Physical Settlement will apply to all conversions of Securities, (ii) at the time of computation of such number of shares, all such Securities would
be converted by a single Holder and (iii) the maximum Conversion Rate permitted by Section 10.14 is applicable to such conversion). The Company shall, from time to time and in accordance with Delaware law, cause the authorized number of
shares of Common Stock to be increased if the aggregate of the number of authorized shares of Common Stock remaining unissued shall not be sufficient for the conversion of all outstanding (and issuable as set forth above) Securities into shares of
Common Stock at any time. 
 All Common Stock issued upon conversion of the Securities shall be validly issued, fully paid and
non-assessable and shall be free of preemptive or similar rights and free of any lien or adverse claim that arises from the action or inaction of the Company. 

The Company shall comply with all securities laws regulating the offer and delivery of any Common Stock upon conversion of Securities and
shall list such shares on each national securities exchange or automated quotation system on which the Common Stock is listed on the applicable Conversion Date. 

  
 57 

 Section 10.06. Adjustment of Conversion Rate. The Conversion Rate shall be subject to
adjustment from time to time, without duplication, upon the occurrence of any of the following events on or after the date of this Indenture: 

(a) In case the Company shall pay or make a dividend or other distribution on its Common Stock consisting exclusively of Common Stock, the
Conversion Rate shall be increased by multiplying such Conversion Rate by a fraction of which the denominator shall be the number of shares of Common Stock outstanding immediately prior to the Open of Business on the Ex Date for such dividend or
distribution, and the numerator shall be the number of shares of Common Stock outstanding immediately after giving effect to such dividend or distribution, based on the following formula: 

 

			
	
CR’ = CR0 ×
	 	 OS’

OS0

	 

  

					
	 where,

			
	 CR0
	 	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex Date of such dividend or distribution;
			
	 CR’
	 	=	  	the Conversion Rate in effect immediately after the Open of Business on the Ex Date for such dividend or distribution;
			
	 OS0
	 	=	  	the number of shares of Common Stock outstanding immediately prior to the Open of Business on the Ex Date for such dividend or distribution; and
			
	 OS’
	 	=	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend or distribution.

 In case the Company shall effect a share split or share combination of the Common Stock, the Conversion Rate
shall be proportionally increased, in the case of a share split, and proportionally reduced, in the case of a share combination, as expressed in the following formula: 
  

			
	
CR’ = CR0 ×
	 	 OS’

OS0

	 

  

					
	 where,

			
	 CR0
	 	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the effective date of such share split or share combination;
			
	 CR’
	 	=	  	the Conversion Rate in effect immediately after the Open of Business on the effective date of such share split or share combination;

  
 58 

					
	 OS0
	 	=	  	the number of shares of Common Stock outstanding immediately prior to the Open of Business on the effective date of such share split or share combination; and
			
	 OS’
	 	=	  	the number of shares of Common Stock outstanding immediately after giving effect to such share split or share combination.

 Any adjustment made under this Section 10.06(a) shall become effective immediately after the Open of
Business on the Ex Date for such dividend or distribution, or immediately after the Open of Business on the effective date for such share split or share combination, as the case may be. If any dividend or distribution of the type described in this
Section 10.06(a) is declared but not so paid or made, then the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay 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 distributes to all or substantially
all holders of the Common Stock any rights, options or warrants entitling them, for a period expiring not more than forty-five (45) days immediately following the date of such distribution, to purchase or subscribe for Common Stock at a price
per share less than the average of the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement for such distribution, the Conversion Rate
shall be increased based on the following formula: 
  

			
	
CR’ = CR0 ×
	 	
OS0 + X

OS0 + Y

	 

  

					
	 where,

			
	 CR0
	 	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex Date for such distribution;
			
	 CR’
	 	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex Date;
			
	 OS0
	 	=	  	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex Date;
			
	 X
	 	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	 Y
	 	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading
Day period ending on the Trading Day immediately preceding the date of announcement for such distribution.

  
 59 

 Any increase made under this Section 10.06(b) shall be made successively whenever any such
rights, options or warrants are distributed and shall become effective immediately after the Open of Business on the Ex Date for such distribution. To the extent that Common Stock is not delivered after expiration of such rights, options or
warrants, the Conversion Rate shall be readjusted, effective as of the date of such expiration, to the Conversion Rate that would then be in effect had the increase with respect to the distribution of such rights, options or warrants been made on
the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not
to make such distribution, to the Conversion Rate that would then be in effect if such Ex Date for such distribution had not occurred. 
 In
determining whether any rights, options or warrants entitle the holders to subscribe for or purchase Common Stock at less than such average of the Closing Sale Prices for the ten (10) consecutive Trading Day period ending on the Trading Day
immediately preceding the date of announcement for such distribution, and in determining the aggregate offering price of such Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or
warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. Except in the case of a readjustment of the Conversion Rate pursuant to the
immediately preceding paragraph, the Conversion Rate shall not be decreased pursuant to this Section 10.06(b). 
 (c) If the Company
distributes shares of its Capital Stock, evidences of its indebtedness or other of its assets, securities or property or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of Common
Stock, but excluding (i) dividends or distributions as to which an adjustment was effected pursuant to Section 10.06(a) or Section 10.06(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment was
effected pursuant to Section 10.06(d), (iii) distributions of Reference Property in a transaction described in Section 10.11, (iv) rights issued pursuant to a rights plan of the Company (i.e., a poison pill), except to the extent
provided by Section 10.13, and (v) Spin-Offs to which the provisions set forth in the latter portion of this Section 10.06(c) shall apply (any of such shares of Capital Stock, indebtedness or other assets, securities or property or
rights, options or warrants to acquire its Capital Stock or other securities, the “Distributed Property”), then, in each such case the Conversion Rate shall be increased based on the following formula: 

 

			
	
CR’ = CR0 ×
	 	 SP0

SP0 – FMV

	 

 where, 
  

					
	CR0	 	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex Date for such distribution;

  
 60 

					
			
	CR’	 	=	  	the Conversion Rate in effect immediately after the Open of Business on the Ex Date for such distribution;
			
	 SP0
	 	=	  	the average of the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on the Trading Day immediately preceding the Ex Date for such distribution; and
			
	 FMV
	 	=	  	the fair market value (as determined by the Board of Directors) of the Distributed Property distributable with respect to each outstanding share of Common Stock as of the Open of Business on the Ex Date for such
distribution.

 If the Board of Directors determines “FMV” for purposes of this Section 10.06(c) by reference
to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day
period ending on the Trading Day immediately preceding the Ex Date for such distribution. 
 Notwithstanding the foregoing, if
“FMV” (as defined above) is equal to or greater than the “SP0” (as defined above), in lieu of the foregoing increase, provision shall be made for each Holder of a Security
to receive, for each $1,000 principal amount of Securities it holds, at the same time and upon the same terms as the holders of the Common Stock, the amount and kind of Distributed Property that such Holder would have received if such Holder had
owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex Date for such distribution. 
 Any increase made
under the portion of this Section 10.06(c) above shall become effective immediately after the Open of Business on the Ex Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased, effective
as of the date the Board of Directors determines not to make such distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

With respect to an adjustment pursuant to this Section 10.06(c) where there has been a payment of a dividend or other distribution on the
Common Stock of Capital Stock of any class or series, or similar equity interests, of or relating to a Subsidiary or other business unit of the Company, where such Capital Stock or similar equity interest is listed or quoted (or will be listed or
quoted upon consummation of the transaction) on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 

 

			
	
CR’ = CR0 ×
	  	
FMV0 + MP0
 MP0

	  

 where, 
  

					
	 CR0
	 	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex Date for the Spin-Off;

  
 61 

					
			
	CR’	 	=	  	the Conversion Rate in effect immediately after the Open of Business on the Ex Date for the Spin-Off;
			
	FMV0	 	=	  	the average of the Closing Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of Common Stock (determined by reference to the definition of Closing Sale
Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the ten (10) consecutive Trading Days immediately following, and including, the Ex Date for a Spin-Off (the
“Valuation Period”); and
			
	MP0	 	=	  	the average of the Closing Sale Prices of the Common Stock over the Valuation Period.

 The increase to the Conversion Rate under the preceding paragraph shall be determined on the last Trading Day
of the Valuation Period, but will be given effect immediately after the Open of Business on the Ex Date for such Spin-Off. Notwithstanding the foregoing, (x) in respect of any conversion during the Valuation Period for which Physical Settlement
is applicable, references in the portion of this Section 10.06(c) related to Spin-Offs with respect to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex Date of such Spin-Off
and the Conversion Date in determining the Conversion Rate and (y) in respect of any conversion during the Valuation Period for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant
Observation Period for such conversion and within the Valuation Period, references in the portion of this Section 10.06(c) related to Spin-Offs with respect to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading
Days as have elapsed between the Ex Date of such Spin-Off and such Trading Day in determining the Conversion Rate as of such Trading Day. If the period from and including the Ex Date for the Spin-Off to and including the last Trading Day of the
Observation Period in respect of any conversion of Securities is less than 10 Trading Days, references in the portion of this Section 10.06(c) related to Spin-Offs with respect to 10 Trading Days shall be deemed to be replaced, solely in
respect of that conversion of Securities, with such lesser number of Trading Days as have elapsed from, and including, the Ex Date for the Spin-Off to, and including, the last Trading Day of such Observation Period. 

Subject in all respects to Section 10.13, rights, options or warrants distributed by the Company to all holders of its Common Stock
entitling the holders thereof to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified
event or events (“Trigger Event”): (i) are deemed to be transferred with such Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not
to have been distributed for purposes of this Section 10.06(c) (and no adjustment to the Conversion Rate under this Section 10.06(c), will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or
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 10.06(c), as the case may be. If any such right, option or warrant, including any such
existing rights, options or warrants distributed prior to the 

  
 62 

 
date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase 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 Ex Date with respect to new rights, options or warrants with such rights (and a termination or expiration of the existing
rights, options or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options 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 10.06(c), as the case may be, was made, (1) in the case of any
such rights, options 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 Common Stock with respect to such rights, options or warrants (assuming such holder
had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without
exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued. 
 For
purposes of Section 10.06(a), Section 10.06(b) and this Section 10.06(c), if any dividend or distribution to which this Section 10.06(c) is applicable also includes one or both of: 

(A) a dividend or distribution of Common Stock to which Section 10.06(a) is applicable (the “Clause A
Distribution”); or 
 (B) a dividend or distribution of rights, options or warrants to which Section 10.06(b)
is applicable (the “Clause B Distribution”), 
 then (1) such dividend or distribution, other than the Clause A Distribution and
Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 10.06(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 10.06(c) with
respect to such Clause C Distribution shall then be made and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by
Section 10.06(a) and Section 10.06(b) with respect thereto shall then be made, except that, if determined by the Board of Directors, the Ex Date of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex Date
of the Clause C Distribution and any Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the Open of Business on the Ex Date for such dividend or
distribution” or “outstanding immediately after the Open of Business on the effective date of such share split or share combination,” as the case may be within the meaning of Section 10.06(a) or “outstanding immediately
prior to the Open of Business on the Ex Date for such distribution” within the meaning of Section 10.06(b). 

  
 63 

 Except in the case of a readjustment of the Conversion Rate pursuant to the last sentence of
either the fourth or seventh paragraph of this Section 10.06(c), the Conversion Rate shall not be decreased pursuant to this Section 10.06(c). 

(d) If any cash dividend or distribution is made to all or substantially all holders of the Common Stock, the Conversion Rate shall be
increased based on the following formula: 
  

			
	 CR1 = CR0 x
	  	 SP0

SP0 – C

	  

 where, 
  

					
	 CR0
	 	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex Date for such dividend or distribution;
			
	 CR1
	 	=	  	the Conversion Rate in effect immediately after the Open of Business on the Ex Date for such dividend or distribution;
			
	 SP0
	 	=	  	the average of the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period immediately preceding the Ex Date for such dividend or distribution (or, if the Company declares such dividend or
distribution less than eleven (11) Trading Days prior to the Ex Date for such dividend or distribution the reference to ten (10) consecutive Trading Days shall be replaced with a smaller number of consecutive Trading Days that shall have occurred
after, and not including, such declaration date and prior to, but not including, the Ex Date for such dividend or distribution); and
			
	 C
	 	=	  	the amount in cash per share of Common Stock the Company distributes to holders of its Common Stock.

 Any adjustment made under this Section 10.06(d) shall become effective immediately after the Open of
Business on the Ex Date for such dividend or distribution. 
 Notwithstanding the foregoing, if “C” (as defined above) is equal to
or greater than “SP0” (as defined above), in lieu of the foregoing increase, provision shall be made for each Holder of a Security to receive, for each $1,000 principal amount of
Securities it holds, at the same time and upon the same terms as holders of the Common Stock, the amount of cash such Holder would have received as if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Ex Date
for such cash dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion
Rate that would then be in effect if such dividend or distribution had not been declared. 
 Except in the case of a readjustment of the
Conversion Rate pursuant to the last sentence of the immediately preceding paragraph, the Conversion Rate shall not be decreased pursuant to this Section 10.06(d). 

  
 64 

 (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or
exchange offer for the Common Stock, if the cash and value of any other consideration included in the payment per share of Common Stock exceeds the average of the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day
period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula: 

 

			
	
CR’ = CR0 ×
	 	
AC + (SP’ × OS’)

OS0 × SP’

	 

  

					
	 where,
  
	  		  	
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Close of Business on the last Trading Day of the ten (10) consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or
exchange offer expires;
			
	CR’	  	=	  	the Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the ten (10) consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or
exchange offer expires;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the time such tender or exchange offer expires (prior to giving effect to such tender offer or exchange offer);
			
	OS’	  	=	  	the number of shares of Common Stock outstanding immediately after the time such tender or exchange offer expires (after giving effect to such tender offer or exchange offer); and
			
	SP’	  	=	  	the average of the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

 The increase to the Conversion Rate under this Section 10.06(e) shall occur at the Close of Business on
the tenth (10th) Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that, for purposes of determining the Conversion Rate, (x) in respect of any
conversion for which Physical Settlement is applicable during the ten (10) Trading Days immediately following, but excluding, the date that any such tender or exchange offer expires, references in this Section 10.06(e) to ten
(10) consecutive Trading Days shall be deemed to be replaced with such lesser number of consecutive Trading Days as have elapsed between the date such tender or exchange offer 

  
 65 

 
expires and the relevant Conversion Date and (y) in respect of any conversion for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the
relevant Observation Period for such conversion and within the ten (10) Trading Days immediately following, but excluding, the date that any such tender or exchange offer expires, references in this Section 10.06(e) to ten
(10) consecutive Trading Days shall be deemed to be replaced with such lesser number of consecutive Trading Days as have elapsed between the date of such tender or exchange offer and such Trading Day in determining the Conversion Rate as of
such Trading Day. If the Company or one of its Subsidiaries is obligated to purchase the Common Stock pursuant to any such tender or exchange offer but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such
purchase or all such purchases are rescinded, the Conversion Rate shall be immediately decreased to the Conversion Rate that would be in effect if such tender or exchange offer had not been made. 

Except in the case of a readjustment of the Conversion Rate pursuant to the last sentence of the immediately preceding paragraph, the
Conversion Rate shall not be decreased pursuant to this Section 10.06(e). 
 (f) In addition to the foregoing adjustments in
subsections (a), (b), (c), (d) and (e) above, and to the extent permitted by applicable law and the rules of the Relevant Stock Exchange, the Company may, from time to time and to the extent permitted by law, increase the Conversion Rate
by any amount for a period of at least twenty (20) Trading Days or any longer period as may be permitted or required by law, if the Board of Directors has made a determination, which determination shall be conclusive, that such increase would
be in the best interests of the Company. Such Conversion Rate increase shall be irrevocable during such period. The Company shall give notice to the Trustee and cause notice of such increase, which notice will include the amount of the increase and
the period during which the increase shall be in effect, to be sent to each Holder of Securities in accordance with Section 14.01, at least fifteen (15) days prior to the date on which such increase commences. 

(g) All calculations under this Article 10 shall be made to the nearest cent or to the nearest 1/10,000th of a share, as the case may be.
Adjustments to the Conversion Rate will be calculated to the nearest 1/10,000th of a share. 

(h) Notwithstanding this Section 10.06 or any other provision of this Indenture or the Securities, if a Conversion Rate adjustment
becomes effective on any Ex Date, and a Holder that has converted its Securities on or after such Ex Date and on or prior to the related record date would be treated as the record holder of the Common Stock as of the related Conversion Date as
described under Section 10.02(b) based on an adjusted Conversion Rate for such Ex Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 10.06, the Conversion Rate adjustment relating to such Ex Date shall
not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such
adjustment. 
 (i) Notwithstanding this Section 10.06 or any other provision of this Indenture or the Securities, if a Holder converts
a Security, Combination Settlement is applicable to such 

  
 66 

 
Security and the Daily Settlement Amount for any Trading Day during the Observation Period applicable to such Security (x) is calculated based on a Conversion Rate adjusted on account of any
event described in clauses (a), (b), (c), (d) and (e) of this Section 10.06 and (y) includes any shares of Common Stock that entitle their holder to participate in such event, then, notwithstanding the Conversion Rate adjustment
provisions in this Section 10.06, the Conversion Rate adjustment relating to such event will not be made for such converting Holder for such Trading Day. Instead, such Holder will be treated as if such Holder were the record owner of the Common
Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment. 
 (j) For
purposes of this Section 10.06, “effective date” means the first date on which the Common Stock trade on the Relevant Stock Exchange, regular way, reflecting the relevant share split or share combination, as applicable. 

(k) For purposes of this Section 10.06, the number of shares of Common Stock 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 shares of Common Stock. The Company shall not pay any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company. 
 Section 10.07. No Adjustment. The Conversion Rate shall not be adjusted for any transaction or event
other than for any transaction or event described in this Article 10. Without limiting the foregoing, the Conversion Rate shall not be adjusted: 

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

(ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or
future employee, director or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries (or the issuance of any shares of Common Stock pursuant to any such options or other rights); 

(iii) upon the issuance of any Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible
security not described in clause (ii) above and outstanding as of the date the Securities were first issued; 
 (iv) for
accrued and unpaid interest, if any; 
 (v) repurchases of Common Stock that are not tender offers or exchange offers
pursuant to Section 10.06(e), including structured or derivative transactions such as accelerated share repurchase transactions or similar forward derivatives; 

(vi) solely for a change in the par value of the Common Stock; or 

  
 67 

 (vii) for the issuance of Common Stock or any securities convertible into or
exchangeable for Common Stock or the right to purchase Common Stock or such convertible or exchangeable securities, except as described in Section 10.06. 

No adjustment in the Conversion Rate of less than one percent (1%) of the Conversion Rate as last adjusted (or, if never adjusted, the
initial Conversion Rate) shall be made pursuant to Section 10.06(a) through Section 10.06(e); provided, however, that (i) the Company shall carry forward any adjustments that are not made as a result of the foregoing and
make such carried forward adjustments with respect to the Conversion Rate when the cumulative effect of all adjustments not yet made will result in a change of one percent (1%) or more of the Conversion Rate as last adjusted (or, if never
adjusted, the initial Conversion Rate) and (ii) notwithstanding the foregoing, all such deferred adjustments that have not yet been made shall be made (including any adjustments that are less than one percent (1%) of the Conversion Rate as
last adjusted (or, if never adjusted, the initial Conversion Rate)) (1) on the effective date of any Fundamental Change or Make-Whole Fundamental Change and (2) on (A) the Conversion Date (in the case of Physical Settlement) and
(B) on each Trading Day of any Observation Period (in the case of Cash Settlement or Combination Settlement). 
 No adjustment to the
Conversion Rate need be made pursuant to Section 10.06 for a transaction (other than for share splits or share combinations pursuant to Section 10.06(a) or tender offers or exchange offers pursuant to Section 10.06(e)) if the Company
makes provision for each Holder to participate in the transaction, at the same time and upon the same terms as holders of Common Stock participate in such transaction, without conversion, as if such Holder held a number of shares of Common Stock
equal to the Conversion Rate in effect on the Ex Date or effective date, as applicable, of the transaction (without giving effect to any adjustment pursuant to Section 10.06 on account of such transaction), multiplied by the principal
amount (expressed in thousands) of Securities held by such Holder. 
 Section 10.08. Other Adjustments. Whenever any provision
of this Indenture requires the computation of an average of the Closing Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a period of multiple Trading Days (including an Observation Period and the period
for determining the Applicable Price for purposes of a Make-Whole Fundamental Change), the Board of Directors, in its good faith determination, shall appropriately adjust such average to account for any event requiring, pursuant hereto, an
adjustment to the Conversion Rate where the effective date, Ex Date or expiration date of such event occurs at any time on or after the first Trading Day of such period and on or prior to the last Trading Day of such period. 

Section 10.09. Adjustments for Tax Purposes. Except as prohibited by law, the Company may (but is not obligated to) make such
increases in the Conversion Rate, in addition to those required by Section 10.06 hereof, as it considers to be advisable to avoid or diminish any income tax to any holders of Common Stock (or rights to purchase Common Stock) resulting from any
dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes or for any other reason.

 Section 10.10. Notice of Adjustment and Certain Events. (a) Whenever the
Conversion Rate is adjusted, the Company shall promptly file with the Trustee an Officers’ Certificate describing in reasonable detail the adjustment and the method of calculation used and the Company shall promptly send to the Holders in
accordance with Section 14.01 a notice of the adjustment setting forth the adjusted Conversion Rate and the calculation thereof. The certificate and notice shall be conclusive evidence of the correctness of such adjustment. In the absence of an
Officers’ Certificate being filed with the Trustee (and the Conversion Agent if not the Trustee), the Trustee may assume without inquiry that the Conversion Rate has not been adjusted and that the last Conversion Rate of which it has knowledge
remains in effect. 
 (b) In case of any: 

(i) action by the Company or one of its Subsidiaries that would require an adjustment to the Conversion Rate in accordance with
Section 10.06 or Section 10.13; 
 (ii) Merger Event; or 

(iii) voluntary or involuntary dissolution, liquidation or winding-up of the Company; 

then the Company shall at least ten days prior to the anticipated effective date of such transaction or event cause written notice thereof to be sent to the
Trustee and the Holders in accordance with Section 14.01 Such notice shall also specify, as applicable, the date or expected date on which the holders of Common Stock shall be entitled to a distribution and the date or expected date on which
the holders of Common Stock shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up, as
the case may be. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event, dissolution, liquidation or winding-up. 

Section 10.11. Effect of Reclassifications, Consolidations, Mergers, Binding Share Exchanges or Sales on Conversion Privilege. If
on or after the date of this Indenture the Company: 
 (a) reclassifies the Common Stock (other than a change as a result of a subdivision
or combination of Common Stock to which Section 10.06(a) applies); 
 (b) is party to a consolidation, merger or binding share
exchange; or 
 (c) sells, transfers, leases, conveys or otherwise disposes of all or substantially all of the consolidated property or
assets of the Company and its Subsidiaries, taken as a whole, 
 in each case, pursuant to which the Common Stock would be converted into or exchanged for,
or would constitute solely the right to receive, cash, securities or other property or assets (any such event, a “Merger Event”), each $1,000 principal amount of converted Securities will, from and after the effective time of such
Merger Event, be convertible into the same kind, type and proportions of consideration that a holder of a number of shares of Common Stock equal to the 

  
 69 

 
Conversion Rate in effect immediately prior to such Merger Event would have received in such Merger Event (“Reference Property” with each “unit of Reference
Property” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person,
as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 9.01(a) providing for such change in the right to convert the Securities; provided, however, that at and after the effective time
of the Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Securities in accordance with Section 10.02 and
(B) (I) any amount payable in cash upon conversion of the Securities in accordance with Section 10.02 shall continue to be payable in cash, (II) any Common Stock that the Company would have been required to deliver upon conversion of
the Securities in accordance with Section 10.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have received in such Merger Event and (III) the Daily VWAP
shall be calculated based on the value of a unit of Reference Property. 
 If the Merger Event causes the Common Stock to be converted into,
or exchanged for, the right to receive more than a single type of consideration determined based in whole or in part upon any form of stockholder election, then (i) the Reference Property into which the Securities will be convertible shall be
deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election (or, if no holders of Common Stock affirmatively make such an election, the types and
amounts of consideration actually received by the holders of Common Stock) and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable
to one share of Common Stock. The Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as reasonably practicable after such determination is made. If the holders of
Common Stock receive only cash in such Merger Event, then for all conversions that occur after the effective date of such Merger Event (A) the consideration due upon conversion of each $1,000 principal amount of Securities shall be solely cash
in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased pursuant to Section 10.14), multiplied by the price paid per share of Common Stock in such Merger Event and (B) the Company shall satisfy its
Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the relevant Conversion Date. 

The supplemental indenture referred to in the first sentence of this Section 10.11 shall provide for adjustments to the Conversion Rate
that shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Rate provided for in this Article 10 and for the delivery of cash by the Company in lieu of fractional securities or property that would otherwise be
deliverable to holders upon Conversion as part of the Reference Property, with such amount of cash determined by the Board of Directors in a manner as nearly equivalent as may be practicable to that used by the Company to determine the Closing Sale
Price of the Common Stock. The provisions of this Section 10.11 shall similarly apply to successive consolidations, mergers, binding share exchanges, sales, transfers, leases, conveyances or dispositions. 

  
 70 

 The Company shall not consummate any Merger Event unless its terms are consistent with this
Section 10.11. 
 None of the foregoing provisions shall affect the right of a Holder to convert its Securities into Common Stock (and
cash in lieu of any fractional share) as set forth in Section 10.01 and Section 10.02 prior to the effective date of such Merger Event. 

In the event the Company shall execute a supplemental indenture in accordance with this Section 10.11, the Company shall promptly file
with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of Reference Property receivable by Holders of the Securities upon the conversion of their Securities after any such Merger Event and any
adjustment to be made with respect thereto. 
 Section 10.12. Trustee’s Disclaimer. The Trustee and the Conversion Agent
shall have no duty to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require that any adjustment under this Article 10 should be made, how it should be made or what such adjustment should be, but may
accept as conclusive evidence of the correctness of any such adjustment, and shall be protected in relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to
Section 10.10 hereof. Neither the Trustee nor the Conversion Agent makes any representation as to the validity or value of any securities or assets issued upon conversion of Securities, and neither the Trustee nor the Conversion Agent shall be
responsible for the failure by the Company to comply with any provisions of this Article 10 or to monitor any Person’s compliance with this Article 10. 

The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture
executed pursuant to Section 10.11, but may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with the
Trustee pursuant to Section 10.11 hereof. 
 Section 10.13. Rights Distributions Pursuant to Shareholders’ Rights
Plans. To the extent that on or after the date of this Indenture the Company adopts a rights plan (i.e., a poison pill) and such plan is in effect upon conversion of any Security or a portion thereof, the Company shall make provision such that
each Holder thereof shall receive, in addition to, and concurrently with the delivery of, the Common Stock due upon conversion (if any), the rights described in such plan, unless the rights have separated from the Common Stock before the time of
conversion, in which case the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all holders of Common Stock, Distributed Property as described in Section 10.06(c), subject to readjustment in the event
of the expiration, termination or redemption of such rights. 
 Section 10.14. Increased Conversion Rate Applicable to Certain
Securities Surrendered in Connection with Make-Whole Fundamental Changes. (a) Notwithstanding anything herein to the contrary, the Conversion Rate applicable to each Security that is surrendered for conversion, in accordance with this
Article 10, at any time during the period (the “Make-Whole Conversion 

  
 71 

 
Period”) from, and including, the effective date (the “Effective Date”) of a Make-Whole Fundamental Change (which Effective Date the Company shall disclose in the
written notice referred to in Section 10.14(e)) (A) if such Make-Whole Fundamental Change does not also constitute a Fundamental Change, to, and including, the Close of Business on the date that is thirty (30) Business Days after the
later of (i) such Effective Date and (ii) the date the Company sends to Holders the relevant notice of the Effective Date or (B) if such Make-Whole Fundamental Change also constitutes a Fundamental Change, to, and including, the Close
of Business on the Fundamental Change Repurchase Date corresponding to such Fundamental Change, shall be increased to an amount equal to the Conversion Rate that would, but for this Section 10.14, otherwise apply to such Security pursuant to
this Article 10, plus an amount equal to the Make-Whole Applicable Increase. 
 (b) As used herein, “Make-Whole Applicable
Increase” shall mean, with respect to a Make-Whole Fundamental Change, the amount, set forth in the following table, which corresponds to the Effective Date and the Applicable Price of such Make-Whole Fundamental Change: 

 

																																													
	 	  	 Applicable Price

 provided, however, that: 

(i) if the actual Applicable Price of such Make-Whole Fundamental Change is between two (2) Applicable Prices listed in
the table above under the row titled “Applicable Price,” or if the actual Effective Date of such Make-Whole Fundamental Change is between two Effective Dates listed in the table above in the column immediately below the title
“Effective Date,” then the Make-Whole Applicable Increase for such Make-Whole Fundamental Change shall be determined by linear interpolation between the Make-Whole Applicable Increases set forth for such higher and lower Applicable Prices,
or for such earlier and later Effective Dates based on a three hundred and sixty-five (365) or three hundred and sixty-six (366) day year, as applicable; 

(ii) if the actual Applicable Price of such Make-Whole Fundamental Change is greater than $17.50 per share (subject to
adjustment in the same manner as the Applicable Prices pursuant to Section 10.14(b)(iii)), or if the actual Applicable Price of such Make-Whole Fundamental Change is less than $3.92 per share (subject to adjustment in the same manner as the
Applicable Prices pursuant to Section 10.14(b)(iii)), then the Make-Whole Applicable Increase shall be equal to zero (0); 

  
 72 

 (iii) if an event occurs that requires, pursuant to this Article 10 (other than
solely pursuant to this Section 10.14), an adjustment to the Conversion Rate, then, on the date and at the time such adjustment is so required to be made, each Applicable Price set forth in the table above under the column titled
“Applicable Price” shall be deemed to be adjusted so that such Applicable Price, at and after such time, shall be equal to the product of (A) such Applicable Price as in effect immediately before such adjustment to such Applicable
Price and (B) a fraction the numerator of which is the Conversion Rate in effect immediately before such adjustment to the Conversion Rate and the denominator of which is the Conversion Rate to be in effect, in accordance with this Article 10,
immediately after such adjustment to the Conversion Rate; and 
 (iv) each Make-Whole Applicable Increase amount set forth in
the table above shall be adjusted in the same manner, for the same events and at the same time as the Conversion Rate is required to be adjusted pursuant to Section 10.06 through Section 10.13. 

(c) Subject to Section 10.11, upon surrender of Securities for conversion in connection with a Make-Whole Fundamental Change, the Company
shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 10.02; provided, however, that if at the effective time of a Make-Whole
Fundamental Change described in clause (b) of the definition of Fundamental Change the consideration for the Common Stock is composed entirely of cash, for any conversion of Securities following the Effective Date of such Make-Whole Fundamental
Change, the Conversion Obligation shall be calculated based solely on the Applicable Price for the transaction and shall be deemed to be an amount equal to, per $1,000 principal amount of converted Securities, the Conversion Rate (including any
Make-Whole Applicable Increase), multiplied by such Applicable Price. In such event, the Conversion Obligation will be determined and shall be paid to Holders in cash on the third Business Day following the Conversion Date. 

(d) As used herein, “Applicable Price” shall have the following meaning with respect to a Make-Whole Fundamental Change:
(i) if such Make-Whole Fundamental Change is a transaction or series of transactions described in clause (b) of the definition of Fundamental Change and the consideration (excluding cash payments for fractional shares or pursuant to
statutory appraisal rights) for Common Stock in such Make-Whole Fundamental Change consists solely of cash, then the “Applicable Price” with respect to such Make-Whole Fundamental Change shall be equal to the cash amount paid per share of
Common Stock in such Make-Whole Fundamental Change and (ii) in all other circumstances, the “Applicable Price” with respect to such Make-Whole Fundamental Change shall be equal to the average of the Closing Sale Prices per share of
Common Stock for the five (5) consecutive Trading Days immediately preceding, but excluding, the Effective Date of such Make-Whole Fundamental Change, which average shall be appropriately adjusted by the Board of Directors, in its good faith
determination, to account for any adjustment, pursuant hereto, to the Conversion Rate that shall become effective, or any event requiring, pursuant hereto, an adjustment to the Conversion Rate where the effective date, Ex Date or expiration date of
such event occurs, at any time during such five (5) consecutive Trading Days. 

  
 73 

 (e) The Company shall send to each Holder, in accordance with Section 14.01, written notice
of the Effective Date of the Make-Whole Fundamental Change within ten (10) days after such Effective Date. Each such notice shall also state that, in connection with such Make-Whole Fundamental Change, the Company shall increase, in accordance
herewith, the Conversion Rate applicable to Securities entitled as provided herein to such increase (along with a description of how such increase shall be calculated and the time periods during which Securities must be surrendered in order to be
entitled to such increase, including, without limitation, the last day of the Make-Whole Conversion Period). 
 (f) For avoidance of doubt,
the provisions of this Section 10.14 shall not affect or diminish the Company’s obligations, if any, pursuant to Article 3 with respect to a Make-Whole Fundamental Change that also constitutes a Fundamental Change. 

(g) Nothing in this Section 10.14 shall prevent an adjustment to the Conversion Rate pursuant to Section 10.06 in respect of a
Make-Whole Fundamental Change. 
 ARTICLE 11 

CONCERNING THE HOLDERS 

Section 11.01. Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage in
aggregate principal amount of the Securities may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the
Holders of such specified percentage have joined therein may be evidenced (i) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, (ii) by the record of
the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 12 or (iii) by a combination of such instrument or instruments and any such record of such a meeting of Holders.
Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Securities, the Company or the Trustee may fix, but shall not be required to, in advance of such solicitation, a date as the record date for determining
Holders entitled to take such action. The record date if one is selected shall be not more than fifteen (15) days prior to the date of commencement of solicitation of such action. 

Section 11.02. Proof of Execution by Holders. Subject to the provisions of Section 12.05, proof of the execution of any
instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of
Securities shall be proved by the security register of the Registrar or by a certificate of the Registrar. The record of any Holders’ meeting shall be proved in the manner provided in Section 12.06. 

Section 11.03. Persons Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any
Conversion Agent and any Registrar may deem the Person in whose name a Security shall be registered upon the security register of the Registrar to be, and may treat it as, the absolute owner of such Security (whether or not such Security shall be
overdue and notwithstanding any notation of ownership or other writing thereon made by any 

  
 74 

 
Person other than the Company or any Registrar) for the purpose of receiving payment of or on account of the principal of and (subject to Section 2.12 and Section 4.01) accrued and
unpaid interest on such Security, or the Fundamental Change Repurchase Price or Redemption Price, if applicable, for conversion of such Security and for all other purposes; and neither the Company nor the Trustee nor any authenticating agent nor any
Paying Agent nor any Conversion Agent nor any Registrar shall be affected by any notice to the contrary. All such payments so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for monies payable upon any such Security. Notwithstanding anything to the contrary in this Indenture or the Securities following an Event of Default, any holder of a beneficial interest in a Global
Security may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depository or any other Person, such holder’s right to exchange such beneficial interest for a Physical
Security in accordance with the provisions of this Indenture. 
 ARTICLE 12 

HOLDERS’ MEETINGS 

Section 12.01. Purpose of Meetings. A meeting of Holders may be called at any time and from time to time pursuant to the
provisions of this Article 12 for any of the following purposes: 
 (a) to give any notice to the Company or to the Trustee or to give any
directions to the Trustee permitted under this Indenture, or to consent to the waiving of any Default or Event of Default hereunder and its consequences, or to take any other action authorized to be taken by Holders pursuant to any of the provisions
of Article 6; 
 (b) to remove the Trustee and nominate a successor trustee pursuant to the provisions of Article 7; 

(c) to consent to the execution of an indenture or indentures supplemental hereto pursuant to the provisions of Section 9.02; or 

(d) to take any other action authorized to be taken by or on behalf of the Holders of any specified aggregate principal amount of the
Securities under any other provision of this Indenture or under applicable law. 
 Section 12.02. Call of Meetings by Trustee.
The Trustee may at any time call a meeting of Holders to take any action specified in Section 12.01, to be held at such time and at such place as the Trustee shall determine. Notice of every meeting of the Holders, setting forth the time and
the place of such meeting and in general terms the action proposed to be taken at such meeting and the establishment of any record date pursuant to Section 11.01, shall be sent to Holders of such Securities at their addresses as they shall
appear on the security register of the Registrar. Such notice shall also be sent to the Company. Such notices shall be sent not less than twenty (20) nor more than ninety (90) days prior to the date fixed for the meeting. 

Any meeting of Holders shall be valid without notice if the Holders of all Securities then outstanding are present in person or by proxy or if
notice is waived before or after the meeting by the Holders of all Securities outstanding, and if the Company and the Trustee are either present by duly authorized representatives or have, before or after the meeting, waived notice. 

  
 75 

 Section 12.03. Call of Meetings by Company or Holders. In case at any time the Company,
pursuant to a Board Resolution, or the Holders of at least 10% in aggregate principal amount of the Securities then outstanding, shall have requested the Trustee to call a meeting of Holders, by written request setting forth in reasonable detail the
action proposed to be taken at the meeting, and the Trustee shall not have sent the notice of such meeting within twenty (20) days after receipt of such request, then the Company or such Holders may determine the time and the place for such
meeting and may call such meeting to take any action authorized in Section 12.01, by sending notice thereof as provided in Section 12.02. 

Section 12.04. Qualifications for Voting. To be entitled to vote at any meeting of Holders a Person shall (a) be a Holder of
one or more Securities on the record date pertaining to such meeting or (b) be a Person appointed by an instrument in writing as proxy by a Holder of one or more Securities on the record date pertaining to such meeting. The only Persons who
shall be entitled to be present or to speak at any meeting of Holders shall be the Persons entitled to vote at such meeting and their counsel and any representatives of the Trustee and its counsel and any representatives of the Company and its
counsel. 
 Section 12.05. Regulations. Notwithstanding any other provision of this Indenture, the Trustee may make such
reasonable regulations as it may deem advisable for any meeting of Holders, in regard to proof of the holding of Securities and of the appointment of proxies, and in regard to the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall think fit. 

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders as provided in Section 12.03, in which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the
meeting shall be elected by vote of the Holders of a majority in aggregate principal amount of the outstanding Securities represented at the meeting and entitled to vote at the meeting. 

Subject to the provisions of Section 2.09, at any meeting of Holders each Holder or proxyholder shall be entitled to one vote for each
$1,000 principal amount of Securities held or represented by such Holder or proxyholder, as the case may be; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not
outstanding and ruled by the chairman of the meeting to be not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Securities held by it or instruments in writing as aforesaid duly designating it as the proxy
to vote on behalf of other Holders. Any meeting of Holders duly called pursuant to the provisions of Section 12.02 or Section 12.03 may be adjourned from time to time by the Holders of a majority of the aggregate principal amount of
outstanding Securities represented at the meeting, whether or not constituting a quorum, and the meeting may be held as so adjourned without further notice. 

  
 76 

 Section 12.06. Voting. The vote upon any resolution submitted to any meeting of
Holders shall be by written ballot on which shall be subscribed the signatures of the Holders or of their representatives by proxy and the outstanding principal amount of the Securities held or represented by them. The permanent chairman of the
meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at
the meeting. A record in duplicate of the proceedings of each meeting of Holders shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken
thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was sent as provided in Section 12.02. The record shall show the principal amount of the
Securities voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to
the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. 
 Any record so signed
and verified shall be conclusive evidence of the matters therein stated. 
 Section 12.07. No Delay of Rights by Meeting.
Nothing contained in this Article 12 shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the

 ARTICLE 13 

REDEMPTION 

Section 13.01. Optional Redemption; Election to Redeem; Notice to Trustee. Prior to April 1, 2020, the Company may not redeem
the Securities. On and after April 1, 2020, the Company may, at its option, redeem the Securities for cash, in whole but not in part, upon notice pursuant to Section 13.03, at a price (the “Redemption Price”) equal to 100%
of the principal amount thereof, plus accrued and unpaid interest, if any, to the Redemption Date (unless the Redemption Date falls after a Record Date but on or prior to the immediately succeeding Interest Payment Date, in which case interest
accrued to the Interest Payment Date will be paid to Holders of record of such Securities on such Record Date, and the Redemption Price will be equal to 100% of the principal amount of such Securities), provided that the Closing Sale Price of
the Common Stock for 20 or more Trading Days (whether or not consecutive and including the Trading Day immediately prior to the date the redemption notice is delivered to Holders) during the period of 30 consecutive Trading Days ending on, and
including, the Trading Day immediately prior to the date the redemption notice is delivered to Holders is equal to or exceeds 150% of the applicable Conversion Price on each applicable Trading Day; provided further that, in the case of a
redemption of any Atairos Securities in whole or in part, the Company shall have 

  
 77 

 
on file with the SEC an effective shelf registration statement of the Company on Form S-3 (or any successor form) for an offering to be made on a delayed or continuous basis pursuant to Rule 415
under the Securities Act (or any similar rule that may be adopted by the SEC) covering the Common Stock. In addition, to the extent such Atairos Securities constitute “Registrable Securities” under the Investment Agreement, if there is a
“Blackout Period” (as defined in the Investment Agreement) covering any time during the period from and including the tenth (10th) Trading Day prior to the Redemption Date to and including the Trading Day immediately prior to the
Redemption Date (the “Open Period”) then the Company shall, as promptly as practicable, notify the Trustee and the Holders of the Atairos Securities (and, in accordance with the Investment Agreement, the beneficial owners parties
thereto of the Atairos Securities) that there is such a Blackout Period, and notwithstanding anything herein to the contrary, the notice of redemption shall automatically be deemed withdrawn with respect to the Atairos Securities, and the Holders of
the Atairos Securities shall have the right, upon notice to the Trustee and the Company delivered within 3 Business Days after the Withdrawal Time to rescind any Conversion Notice that is pending as of the Withdrawal Time and/or to rescind any
conversion of Atairos Securities pursuant to Article 10 with respect to which the Settlement Amount has, as of the Withdrawal Time, not yet been delivered to such Holder or its designee. 

Any redemption pursuant to this Section 13.01 shall be made pursuant to the provisions of this Article 13. The election of the Company to
redeem the Securities pursuant to this Article 13 shall be evidenced by a Board Resolution. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction. As used herein, the “Redemption Date” means the date specified for redemption of the
Securities in accordance with the terms of this Article 13. 
 No Securities may be redeemed by the Company pursuant to this Article 13
if the payment of the principal amount of the Securities has been accelerated, and such acceleration has not been rescinded by the Holders, on or prior to the Redemption Date. 

Section 13.02. [Reserved]. 

Section 13.03. Notice of Redemption. Notice of redemption shall be given by first-class mail, postage prepaid (or in accordance
with the Applicable Procedures in the case of Global Securities), delivered not less than, as the case may be, 50 days (with respect to any redemption of Atairos Securities) or less than 30 days (with respect to any redemption of Securities other
than Atairos Securities), and not more than 60 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to each Holder of Securities to be redeemed, at its address appearing in the security register;
provided, however, that the Company shall not deliver any notice of redemption to any Holder at any time when there exists any Default or Event of Default. 

All notices of redemption shall identify the Securities (including CUSIP number(s)) to be redeemed and shall state: 

(i) the Redemption Date; 

  
 78 

 (ii) the Redemption Price; 

(iii) that Holders have a right to convert the Securities called for redemption upon satisfaction of the requirements set forth
in Section 10.02; 
 (iv) the time at which the Holders’ right to convert the Securities called for redemption will
expire, which will be the close of business on the Business Day immediately preceding the Redemption Date; 
 (v) the
Conversion Rate, any adjustments thereto, and the Settlement Method that shall apply during the redemption period; 
 (vi)
the procedures a Holder must follow to convert its Securities; 
 (vii) that on the Redemption Date the Redemption Price will
become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date; and 

(viii) the place or places where each such Security is to be surrendered for payment of the Redemption Price. 

Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s
written request with 10 Business Days’ advance notice (unless a shorter period is agreed to by the Trustee), by the Trustee in the name and at the expense of the Company. Until and including the date that is 30 days prior to the Redemption
Date, the Company may revoke, in whole, but not in part, any notice of redemption of Atairos Securities delivered under this Article 13. 

Section 13.04. 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 Section 2.04) an amount of money sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date. 
 If any
Security called for redemption is converted, any money deposited with the Trustee or with a Paying Agent or so segregated and held in trust for the redemption of such Security shall be paid to the Company on at the Company’s request, or if then
held by the Company, shall be discharged from such trust. 
 Section 13.05. Securities Payable on Redemption Date. Notice of
redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the
payment of the Redemption Price) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price. 

  
 79 

 If any Security 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 prescribed therefor in the Security.

The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”)
given pursuant to this Indenture and delivered using the following communications methods: e-mail, facsimile transmission, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the
Trustee, or another method or system specified by the Trustee as available for use in connection with its services hereunder (collectively, “Electronic Means”); provided, however, that the Company shall provide to the
Trustee an incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended
by the Company whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s
understanding of such Instructions shall be deemed controlling. The Company understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that
directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers
transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt
by the Company. The Trustee shall not be liable for any losses, costs or expenses (except to the extent attributable to the Trustee’s gross negligence, willful misconduct or bad faith) arising directly or indirectly from the Trustee’s
reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Company agrees: (i) to assume all risks arising out of

  
 81 

 
the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and
misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the
method(s) selected by the Company; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and
circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures. 

Section 14.02. Communication by Holders with Other Holders. To the extent the TIA is then applicable: (A) The Company,
the Trustee, the Registrar and anyone else shall have the protection of TIA §312(c) and (B) Holders may communicate pursuant to TIA §312(b) with other Holders with respect to their rights under this Indenture or the Securities. 

Section 14.03. Certificate and Opinion as to Conditions Precedent. Upon any request or application by the Company to the Trustee
to take any action under this Indenture, the Company shall furnish to the Trustee: 
 (a) an Officers’ Certificate stating that, in the
opinion of the signatories to such Officers’ Certificate, all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with; and 

(b) an Opinion of Counsel stating that, in the opinion of such counsel, all such conditions precedent have been complied with. 

Each signatory to an Officers’ Certificate or an Opinion of Counsel may (if so stated) rely, effectively, upon an Opinion of Counsel as
to legal matters and an Officers’ Certificate or certificates of public officials or other representations or documents as to factual matters. 

Section 14.04. Statements Required in Certificate or Opinion. Each Officers’ Certificate or Opinion of Counsel with respect
to compliance with a condition or covenant provided for in this Indenture (other than a certificate provided pursuant to TIA § 314(a)(4)) which shall comply with the provisions of TIA § 314(e) and shall include: 

(a) a statement that the Person making such certificate or opinion has read such covenant or condition; 

(b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such
certificate or opinion are based; 
 (c) a statement that, in the opinion of such Person, he or she has made such examination or
investigation as is necessary to enable him or her to express an informed opinion as to whether or not such covenant or condition has been complied with; and 

(d) a statement as to whether or not, in the opinion of such Person, such condition or covenant has been complied with.

 Section 14.05. Rules by Trustee and Agents. The Registrar, Paying Agent or Conversion
Agent may make reasonable rules and set reasonable requirements for their respective functions.

Section 14.07. Duplicate Originals. The parties may sign any number of copies of this Indenture. Each signed copy shall be an
original, but all of them together represent the same agreement. Delivery of an executed counterpart by facsimile shall be effective as delivery of a manually executed counterpart thereof.

law; 
 (c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or
certified mail (or any substantially similar form of mail), postage prepaid, to the party, as the case may be, at its address set forth in Section 14.01 or at such other address of which the other party shall have been notified pursuant
thereto; 
 (d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall
limit the right to sue in any other jurisdiction for recognition and enforcement of any judgment or if jurisdiction in the courts referenced in the foregoing clause (a) are not available despite the intentions of the parties hereto; 

  
 83 

 (e) agrees that final judgment in any such suit, action or proceeding brought in such a court may
be enforced in the courts of any jurisdiction to which such party is subject by a suit upon such judgment, provided that service of process is effected upon such party in the manner specified herein or as otherwise permitted by law; 

(f) agrees that to the extent that such party has or hereafter may acquire any immunity from jurisdiction of any court or from any legal
process with respect to itself or its property, such party hereby irrevocably waives such immunity in respect of its obligations under this Indenture, to the extent permitted by law; and

 Section 14.13. Table of Contents, Headings, Etc. The Table of Contents, Cross-Reference
Table and headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part hereof and shall in no way modify or restrict any of the terms or provisions hereof. 

Section 14.14. Calculations in Respect of the Securities. The Company and its agents shall make all calculations under this

provide a copy of such calculations to the Trustee (and the Conversion Agent if not the Trustee) as required hereunder, and, the Trustee shall be entitled to conclusively rely on the accuracy of any such calculation without independent verification.
The Trustee will forward the Company’s calculations to any Holder upon the request of that Holder at the sole cost and expense of the Company. 

  
 84

Agent and the Conversion Agent, as applicable, shall have the right to deduct and withhold from any payment or distribution made with respect to this Indenture and any Security (or the issuance of shares of Common Stock upon conversion of the
Security) such amounts as are required to be deducted or withheld with respect to the making of such payment or distribution (or issuance) under any applicable tax law (inclusive of rules, regulations and interpretations promulgated by competent
authorities) without liability therefor. To the extent that any amounts are so deducted or withheld, such deducted or withheld 

  
 85 

 
amounts shall be treated for all purposes under this Security as having been paid to the Holder. In the event the Company, the Trustee, the Registrar, the Paying Agent or the Conversion Agent
previously remitted any amounts to a governmental entity on account of taxes required to be deducted or withheld in respect of any payment or distribution (or deemed distribution) under this Indenture or with respect to any Security, the Company,
the Registrar, the Paying Agent or the Conversion Agent, as applicable, shall be entitled to offset any such amounts against any amounts otherwise payable in respect of this Indenture or any Security (or the issuance of shares of Common Stock upon
conversion).

USA PATRIOT Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that

GROUPON, INC. 
 3.25%
Convertible Senior Notes Due 2022 
 1. Interest. Groupon, Inc., a Delaware corporation (the “Company”),
promises to pay interest on the principal amount of this Security at the rate per annum shown above. The Company will pay interest, payable annually in arrears, on April 1 of each year, with the first payment to be made on April 1, 2017.
Interest on the Securities will accrue on the principal amount from, and including, the most recent date to which interest has been paid or provided for or, if no interest has been paid, from, and including, April 4, 2016, in each case to, but
excluding, the next Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company shall pay, in cash, interest on any overdue amount (including, to the extent permitted by applicable law,
overdue interest) at the rate borne by the Securities. In certain circumstances, Additional Interest will be payable in accordance with Section 4.03(d), Section 4.03(e) and Section 6.02(b) of the Indenture (as defined below) and any
reference to “interest” shall be deemed to include any such Additional Interest. 
 2. Maturity. The Securities will mature
on the Maturity Date. 
 3. Method of Payment. Except as provided in the Indenture, the Company will pay interest on the Securities
to the Persons who are Holders of record of Securities at the Close of Business on the Record Date set forth on the face of this Security immediately preceding the applicable Interest Payment Date. Holders must surrender Securities to a Paying Agent
to collect the principal amount plus, if applicable, accrued and unpaid interest, if any, or the Fundamental Change Repurchase Price or Redemption Price, payable as herein provided on the Maturity Date, or on any Fundamental Change Repurchase Date
or Redemption Date, as applicable. 
 4. Paying Agent, Registrar, Conversion Agent. Initially, U.S. Bank National Association (the
“Trustee”) will act as Paying Agent, Registrar and Conversion Agent. The Company may change any Paying Agent, Registrar or Conversion Agent without prior notice. 

5. Indenture. The Company issued the Securities under an Indenture dated as of April 4, 2016 (the “Indenture”)
between the Company and the Trustee. The Securities are subject to all terms set forth in the Indenture, and Holders are referred to the Indenture for a statement of such terms. The Securities are unsecured senior obligations of the Company limited
to $250,000,000 aggregate principal amount, except as otherwise provided in the Indenture (and except for Securities issued in substitution for destroyed, lost or wrongfully taken Securities). Terms used herein without definition and which are
defined in the Indenture have the meanings assigned to them in the Indenture. In the event of any inconsistency between the terms of this Security and the terms of the Indenture, the terms of the Indenture shall control. 

6. Redemption. Prior to April 1, 2020, the Company may not redeem the Securities. On and after April 1, 2020, the Company
may, at its option, redeem the Securities for cash, in whole but not in part, on the terms and subject to the provisions set forth in the Indenture. A sinking fund is not provided for the Securities. 

  
 A-3 

 7. Repurchase at Option of Holder Upon a Fundamental Change. Subject to the terms and
conditions of the Indenture, in the event of a Fundamental Change, each Holder of the Securities shall have the right, at the Holder’s option, to require the Company to repurchase such Holder’s Securities including any portion thereof
which is $1,000 in principal amount or any integral multiple thereof on the Fundamental Change Repurchase Date at a price payable in cash equal to the Fundamental Change Repurchase Price. 

8. Conversion. The Securities shall be convertible into cash, Common Stock or a combination of cash and Common Stock, at the
Company’s election, as specified in the Indenture. To convert a Security, a Holder must satisfy the requirements of Section 10.02(a) of the Indenture. A Holder may convert a portion of a Security if the portion is $1,000 principal amount
or an integral multiple of $1,000 principal amount. 
 Upon conversion of a Security, the Holder thereof shall be entitled to receive the
cash and/or Common Stock payable upon conversion in accordance with Article 10 of the Indenture. 
 9. Denominations, Transfer,
Exchange. The Securities are in registered form, without coupons, in denominations of $1,000 principal amount and integral multiples of $1,000 principal amount. The transfer of Securities may be registered and Securities may be exchanged as
provided in the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents. 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 transfer tax or similar governmental charge that may be imposed in connection with certain transfers or exchanges as set forth in the Indenture. The Company or the Trustee, as the case may be, shall
not be required to register the transfer of or exchange any Security for which a Repurchase Notice has been delivered, and not withdrawn, in accordance with the Indenture, except the unrepurchased portion of Securities being repurchased in part.

 10. Persons Deemed Owners. The registered Holder of a Security will be treated as its owner for all purposes. Only registered
Holders of Securities shall have the rights under the Indenture. 
 11. Amendments, Supplements and Waivers. The Indenture contains
provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Securities, and in certain other circumstances, with the consent of the Holders of at least a majority in aggregate principal
amount of the outstanding Securities and in other circumstances with consent of the Holders of 100% of the aggregate principal amount of the outstanding Securities, to amend or supplement the Indenture or the Securities. 

12. Defaults and Remedies. Subject to certain exceptions, if an Event of Default occurs and is continuing, the Trustee by notice to the
Company or the Holders of at least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding by notice to the Company and the Trustee may declare the principal of, and any accrued and unpaid interest

on, all Securities to be due and payable immediately. If any of certain bankruptcy or insolvency-related Events of Default occurs and is continuing, the principal of, and accrued and unpaid
interest on, all the Securities shall automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. Subject to certain exceptions, the Holders of a majority in aggregate
principal amount of the Securities then outstanding by written notice to the Trustee may rescind or annul an acceleration and its consequences if certain conditions specified in the Indenture are satisfied. 

13. Trustee Dealings with the Company. The Trustee under the Indenture, or any banking institution serving as successor Trustee
thereunder, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for, the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee. 

14. Authentication. This Security shall not be valid until authenticated by the manual signature of the Trustee or an authenticating
agent in accordance with the Indenture. 
 15. 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 right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (Uniform Gifts to Minors Act). 

16. Ranking. The Securities shall be senior unsecured obligations of the Company and will rank equal in right of payment to all senior
unsecured indebtedness of the Company, and will rank senior in right of payment to any indebtedness that is contractually subordinated to the Securities.
