 - 7 - 








 All Securities of one Series need not be issued at the same time and, unless otherwise provided,
a Series may be reopened for issuances of additional Securities of such Series pursuant to an Authorizing Resolution, an Officers’ Certificate or in any indenture supplemental hereto. 

The creation and issuance of a Series and the authentication and delivery thereof are not subject to any conditions precedent. If any of the
terms of a Series are established pursuant to an Authorizing Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the
initial issuance of Securities of such Series. The terms of the Securities of any Series may provide that such Securities shall be authenticated and delivered by the Trustee upon original issuance from time to time upon written order of persons
designated in such Authorizing Resolution or supplemental indenture and that such persons are authorized to determine, consistent with such Authorizing Resolution or supplemental indenture, such terms and conditions of the Securities of such series.

 Section 2.02.    Execution and Authentication. 

One Officer shall sign the Securities for the Company by manual or facsimile signature. Each Guarantor shall execute the Guarantee in the
manner set forth in Section 9.07. 
 If an Officer whose signature is on a Security no longer holds that office at the time the
Trustee authenticates the Security, the Security shall nevertheless be valid. 
 A Security shall not be valid until the Trustee manually
signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Base Indenture. 

The Trustee shall authenticate Securities for original issue upon receipt of an Officers’ Certificate of the Company. Each Security shall
be dated the date of its authentication. 
 Section 2.03.    Registrar and Paying Agent. 

The Company shall maintain an office or agency where Securities may be presented for registration of transfer or where Securities of a Series
that are convertible or exchangeable may be surrendered for conversion or exchange (“Registrar”), an office or agency where Securities may be presented for payment (“Paying Agent”) and an office or agency where
notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Registrar shall keep a register of the Securities and of their transfer and exchange (the “Security Register”). The
Company may have one or more co-Registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent. 

The Company shall enter into an appropriate agency agreement with any Agent not a party to this Base Indenture. The agreement shall implement
the provisions of this Indenture that relate to such Agent. The Company shall promptly notify the Trustee in writing of the name and address of any such Agent and the Trustee shall have the right to inspect the Securities Register at all reasonable
times to obtain copies thereof, and the Trustee shall have the right to rely upon such register as to the names and addresses of the Holders and the principal amounts and certificate numbers thereof. If the Company fails to maintain a Registrar or
Paying Agent or fails to give the foregoing notice, the Trustee shall act as such. 
 The Company initially appoints the Trustee as
Registrar and Paying Agent. 
 Section 2.04.    Paying Agent to Hold Money in Trust. 

Each Paying Agent shall hold in trust for the benefit of Securityholders and the Trustee all money held by the Paying Agent for the payment of
principal of or interest on the Securities, and shall notify the Trustee of any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money and hold it as a separate trust
fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon doing so the Paying Agent shall have no further liability for the money. 

  
 - 8 - 








 Section 2.05.    Securityholder 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
Securityholders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least five (5) Business Days before each interest payment date 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 Securityholders. 

Section 2.06.    Transfer and Exchange. 

Where a Security is presented to the Registrar or a co-Registrar with a request to register a transfer, the Registrar shall register the
transfer as requested if the requirements of Section 8-401(a) of the NYUCC are met and the other provisions of this Section 2.06 are satisfied. Where Securities are presented to the Registrar or a co-Registrar with a request to
exchange them for an equal principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. To permit transfers and exchanges, the Trustee shall authenticate Securities at
the Registrar’s request. The Registrar need not transfer or exchange any Security selected for redemption or repurchase, except the unredeemed or repurchased part thereof if the Security is redeemed or repurchased in part, or transfer or
exchange any Securities for a period of 15 days before a selection of Securities to be redeemed or repurchased. Any exchange or transfer shall be without charge, except that the Company may require payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto except in the case of exchanges pursuant to 2.09, 3.06, or 10.05 not involving any transfer. 

Any Holder of a Global Security shall, by acceptance of such Global Security, agree that transfers of beneficial interests in such Global
Security may be effected only through a book entry system maintained by the Holder of such Global Security (or its agent), and that ownership of a beneficial interest in the Security shall be required to be reflected in a book entry. 

Section 2.07.    Replacement Securities. 

If the Holder of a Security claims that the Security has been lost, destroyed, mutilated or wrongfully taken, the Company shall issue and
execute a replacement security, the Guarantors shall execute the related Guarantee and, upon written request of any Officer of the Company, the Trustee shall authenticate such replacement Security, provided, in the case of a lost, destroyed
or wrongfully taken Security, that the requirements of Section 8-405 of the NYUCC are met. If any such lost, destroyed, mutilated or wrongfully taken Security shall have matured or shall be about to mature, the Company may, instead of issuing a
substitute Security therefor, pay such Security without requiring (except in the case of a mutilated Security) the surrender thereof. An indemnity bond must be sufficient in the judgment of the Company and the Trustee to protect the Company, the
Trustee and any Agent from any loss which any of them may suffer if a Security is replaced, including the acquisition of such Security by a bona fide purchaser. The Company and the Trustee may charge for its expenses in replacing a Security. 

Section 2.08.    Outstanding Securities. 

Securities outstanding at any time are all Securities authenticated by the Trustee except: 

(a) Securities theretofore canceled by the Trustee or delivered to the Trustee for cancellation; 

(b) Securities, or portions thereof, for the payment or redemption of which funds in the necessary amount shall have been
deposited in trust with the Trustee or with any paying agent other than the Company, or, if the Company shall act as its own paying agent, shall have been set aside, segregated and held in trust by the Company for the Holders of such Securities,
provided that if such Securities, or portions thereof, are to be redeemed prior to the maturity thereof, notice of such redemption shall have been given as herein provided, or provision satisfactory to the Trustee shall have been made for giving
such notice; and 

  
 - 9 - 








 (c) Securities in substitution for which other Securities shall have been
authenticated and delivered, or which shall have been paid, pursuant to the terms of Section 2.07, except with respect to any such Security as to which proof satisfactory to the Trustee is presented that such Security is held by a person in
whose hands such Security is a legal, valid and binding obligation of the Company. 
 In determining whether the holders of the requisite
principal amount of outstanding Securities of any series have given any request, demand, authorization, direction, notice, consent or waiver hereunder, the principal amount of an Original Issue Discount Security that shall be deemed to be
outstanding for such purposes shall be the amount of the principal thereof that would be due and payable as of the date of such determination upon a declaration of acceleration of the maturity thereof pursuant to Section 6.02 and the
principal amount of a Security denominated in one or more currencies that shall be deemed to be outstanding for such purposes shall be based on the Dollar Equivalent, on the date of original issuance of such Security, of the principal amount of such
Security. 
 Subject to Section 2.12, a Security does not cease to be outstanding because the Company, any Guarantor or one of
their Affiliates holds the Security. 
 Subject to the foregoing provisions of this Section, each Security delivered under this Indenture
upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 

Section 2.09.    Temporary Securities. 

Until Definitive Securities are ready for delivery, the Company may prepare and the Trustee 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, upon surrender for
cancellation of the temporary Security, the Company and the Guarantors shall execute and the Trustee shall authenticate Definitive Securities in exchange for temporary Securities. Until so exchanged, the temporary Securities shall in all respects be
entitled to the same benefits under this Indenture as Definitive Securities authenticated and delivered hereunder. 

Section 2.10.    Cancellation. 

The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Securities surrendered to them for registration of transfer, exchange, redemption, purchase or payment. The Trustee and no one else shall cancel and destroy, or retain in accordance with its standard retention policy, all Securities surrendered for
registration of transfer, exchange, redemption, purchase, payment or cancellation. Unless the Authorizing Resolution or supplemental indenture so provides, the Company may not issue new Securities to replace Securities that it has previously paid or
delivered to the Trustee for cancellation. 
 Section 2.11.    Defaulted Interest. 

If the Company defaults in a payment of interest on the Securities of any Series, it shall pay the defaulted interest plus any interest
payable on the defaulted interest to the persons who are Securityholders of such Series on a subsequent special record date. The Company shall fix such special record date and a payment date which shall be reasonably satisfactory to the Trustee. At
least 15 days before such special record date, the Company shall mail to each Securityholder of the relevant Series a notice that states the record date, the payment date and the amount of defaulted interest to be paid. On or before the date
such notice is mailed, the Company shall deposit with the Paying Agent money sufficient to pay the amount of defaulted interest to be so paid. The Company may pay defaulted interest in any other lawful manner if, after notice given by the Company to
the Trustee of the proposed payment, such manner of payment shall be deemed practicable by the Trustee.

 Section 2.12.    Treasury Securities. 

In determining whether the Holders of the required principal amount of Securities of a Series have concurred in any direction, waiver, consent
or notice, Securities owned by the Company, the Guarantors or any of their respective Affiliates shall be considered as though they are 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 which the Trustee actually knows are so owned shall be so considered. 

Section 2.13.    CUSIP/ISIN Numbers. 

The Company in issuing the Securities of any Series may use a “CUSIP” and/or “ISIN” or other similar number, and if so, the
Trustee shall use the CUSIP and/or ISIN or other similar number in notices of redemption or exchange as a convenience to Holders of such Securities; provided that no representation is hereby deemed to be made by the Trustee as to the
correctness or accuracy of any such CUSIP and/or ISIN or other similar number printed in the notice or on such Securities, and that reliance may be placed only on the other identification numbers printed on such Securities. The Company shall
promptly notify the Trustee of any change in any CUSIP and/or ISIN or other similar number. 
 Section 2.14.    Deposit of
Moneys. 
 Prior to 11:00 a.m. New York City time on each interest payment date and maturity date with respect to each Series of
Securities, the Company shall have deposited with the Paying Agent in immediately available funds money in the applicable currency sufficient to make cash payments due on such interest payment date or maturity date, as the case may be, in a timely
manner which permits the Paying Agent to remit payment to the Holders of such Series on such interest payment date or maturity date, as the case may be. 

Section 2.15.    Book-Entry Provisions for Global Security. 

(a) Any Global Security of a Series initially shall (i) be registered in the name of the Depositary or the nominee of such Depositary,
(ii) be delivered to the Trustee as custodian for such Depositary and (iii) bear any required legends. 
 Members of, or
participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Security,
and the Depositary 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. Notwithstanding the foregoing, nothing herein shall prevent the
Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of
customary practices governing the exercise of the rights of a Holder of any Security. 
 (b) Transfers of any Global Security shall be
limited to transfers in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in the Global Security may be transferred or exchanged for Definitive Securities in accordance with the
rules and procedures of the Depositary. In addition, Definitive Securities shall be transferred to all beneficial owners in exchange for their beneficial interests in a Global Security if (i) the Depositary notifies the Company that it is
unwilling or unable to continue as Depositary for the Global Security and a successor depository is not appointed by the Company within 90 days of such notice or (ii) an Event of Default has occurred and is continuing and the Registrar has
received a request from the Depositary to issue Definitive Securities. 
 (c) In connection with any transfer or exchange of a portion of
the beneficial interest in any Global Security to beneficial owners pursuant to paragraph (b), the Registrar shall (if one or more Definitive Securities are to be issued) reflect on its books and records the date and a decrease in the
principal amount of the Global Security in an amount equal to the principal amount of the beneficial interest in the Global Security to be transferred, and the Company and the Guarantors shall execute, and the Trustee shall authenticate and deliver,
one or more Definitive Securities of like Series and amount. 

  
 - 11 - 








 (d) In connection with the transfer of an entire Global Security to beneficial owners pursuant to
paragraph (b), the Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company and the Guarantors shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the
Depositary in exchange for its beneficial interest in the Global Security, an equal aggregate principal amount of Definitive Securities of the same Series in authorized denominations. 

(e) The Holder of any Global Security may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold
interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities of such Series. 

(f) Unless otherwise provided in the Authorizing Resolution or supplemental indenture for a particular Series of Securities, each Global
Security of such Series shall bear legends in substantially the following forms: 
 “THIS GLOBAL SECURITY IS HELD BY THE
DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS SECURITY) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE HOLDERS OF BENEFICIAL INTERESTS HEREIN, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE
MAY MAKE ANY SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO THE INDENTURE, (II) THIS GLOBAL SECURITY MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.06 OF THE INDENTURE, (III) THIS GLOBAL SECURITY MAY BE DELIVERED TO THE
TRUSTEE FOR CANCELLATION PURSUANT TO THE INDENTURE AND (IV) THIS GLOBAL SECURITY MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY.” 

“UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE
TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR TO ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A
NOMINEE OF SUCH SUCCESSOR DEPOSITARY. UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITARY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN
THE NAME OF ANY ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITARY (AND ANY PAYMENT IS MADE TO SUCH ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITARY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR
VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF HAS AN INTEREST HEREIN.” 
 ARTICLE THREE

 REDEMPTION 

Section 3.01.    Notices to Trustee. 

Securities of a Series that are redeemable prior to maturity shall be redeemable in accordance with their terms and, unless the Authorizing
Resolution or supplemental indenture provides otherwise, in accordance with this Article Three. 
 If the Securities of a Series are
redeemable at the option of the Company and the Company desires to exercise such right to redeem all or, as the case may be, a portion of such Securities, it shall notify the Trustee in 

  
 - 12 - 








 writing of the redemption date and the principal amount of Securities to be redeemed. Any such notice may be
cancelled at any time prior to notice of such redemption being mailed to Holders. Any such cancelled notice shall be void and of no effect. 

If the Securities of a Series are subject to mandatory redemption, repurchase or repayment and the Company wants to credit any Securities
previously redeemed, acquired or retired against any such requirement, it shall notify the Trustee of the amount of the credit and it shall deliver any Securities not previously delivered to the Trustee for cancellation with such notice. 

The Company shall give each notice provided for in this Section 3.01 at least 30 days before the notice of any such redemption is
to be mailed to Holders (unless a shorter notice shall be satisfactory to the Trustee). 
 Section 3.02.    Selection of
Securities to be Redeemed. 
 If fewer than all of the Securities of a Series are to be redeemed, the Trustee shall select the
Securities to be redeemed by a method the Trustee considers fair and appropriate and in a manner that complies with applicable requirements of the Depositary. The Trustee shall make the selection from Securities outstanding not previously called for
redemption and shall promptly notify the Company of the serial numbers or other identifying attributes of the Securities so selected. The Trustee may select for redemption portions of the principal of Securities that have denominations larger than
the minimum denomination for the Series. Securities and portions of them it selects shall be in amounts equal to a permissible denomination for the Series. Provisions of this Indenture that apply to Securities called for redemption also apply to
portions of Securities called for redemption. 
 Unless otherwise provided in the Authorizing Resolution or supplemental indenture relating
to a Series, if any Security selected for partial redemption is converted into or exchanged for common shares of the Company or other securities, cash or other property in part before termination of the conversion or exchange right with respect to
the portion of the Security so selected, the converted or exchanged portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted or exchanged during a selection of
Securities to be redeemed shall be treated by the Trustee as outstanding for the purpose of such selection. 

Section 3.03.    Notice of Redemption. 

At least 30 days but not more than 60 days before a redemption date, the Company shall mail a notice of redemption by first-class mail, postage
prepaid, to each Holder of Securities to be redeemed, at its last address as it shall appear in the Security Register. 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. So long as Securities of any Series issued hereunder are registered in the name of the Depositary or its nominee, such notice shall be given in accordance
with the rules of the Depositary. 
 The notice shall identify the Securities to be redeemed and shall state: 

 

	 	(1)	the redemption date; 

  

	 	(2)	the redemption price or the formula pursuant to which such price will be calculated; 

  

	 	(3)	if any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that, after the redemption date, upon surrender of such Security, a new Security or Securities in
principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Security; 

  

	 	(4)	 in the case of Securities of a Series that are convertible or exchangeable into common shares of the Company or other securities, cash or other
property, the conversion or exchange price or rate, the 



  
 - 13 - 









	 	date or dates on which the right to convert or exchange the principal of the Securities of such Series to be redeemed will commence or terminate and the place or places where such Securities may be surrendered for
conversion or exchange; 

  

	 	(5)	the name and address of the Paying Agent; 

  

	 	(6)	that Securities called for redemption must be surrendered to the Paying Agent to collect the redemption price; 

  

	 	(7)	that interest on Securities or portions of Securities called for redemption ceases to accrue on and after the redemption date; and 

  

	 	(8)	that the Securities are being redeemed pursuant to the mandatory redemption or the optional redemption provisions, as applicable. 


At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense; provided,
however, that the Company shall deliver to the Trustee at least 15 days prior to the date on which notice of redemption is to be mailed or such shorter period as may be satisfactory to the Trustee, an Officers’ Certificate requesting
that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 

Section 3.04.    Effect of Notice of Redemption. 

Once notice of redemption is mailed, Securities or portions of Securities called for redemption become due and payable on the redemption date
and at the redemption price as set forth in the notice of redemption, which notice, and which obligations to redeem the Securities may, at the Company’s discretion, be subject to one or more conditions precedent as set forth in such notice.
Upon surrender to the Paying Agent, such Securities or portions of Securities shall be paid at the redemption price, plus accrued and unpaid interest to the redemption date on the Securities or portions of Securities redeemed (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). 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. 

Section 3.05.    Deposit of Redemption Price. 

On or before the redemption date, the Company shall deposit with the Paying Agent immediately available funds in the applicable currency
sufficient to pay the redemption price of and accrued interest on all Securities to be redeemed on that date. 

Section 3.06.    Securities Redeemed in Part. 

Upon surrender of a Security that is redeemed in part, the Company and the Guarantors shall execute and the Trustee shall authenticate for each
Holder a new Security of the same Series equal in principal amount to the unredeemed portion of the Security surrendered.

Section 4.04.    Waiver of Stay, Extension or Usury Laws. 

The Company and the Guarantors covenant (to the extent that they may lawfully do so) that they will not at any time insist upon, plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the Company or any Guarantor from paying all or any portion of the principal of or interest on
the Securities of any Series as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) the Company and each
of the Guarantors expressly waives all benefit or advantage of any such law, and covenants that it will not 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 had been enacted. 
 Section 4.05.    Appointment to Fill Vacancy in Office of Trustee.

 The Company, whenever necessary to avoid or to fill a vacancy in the office of Trustee, will appoint, in the manner provided in
Section 7.08, a Trustee, so that there shall be at all times a Trustee hereunder. 
 ARTICLE FIVE 

SUCCESSOR CORPORATION 

Section 5.01.    When Company May Merge, etc. 

Neither the Company nor any Guarantor will consolidate or merge with or into, or sell, lease, convey or otherwise dispose of all or
substantially all of its assets (including by way of liquidation or dissolution), to any Person (in each case other than in a transaction in which the Company or a Guarantor is the survivor of a consolidation or merger, or the transferee in a sale,
lease, conveyance or other disposition) unless: 
 (1) the Person formed by or surviving such consolidation or merger (if
other than the Company or the Guarantor, as the case may be), or to which such sale, lease, conveyance or other disposition will be made (collectively, the “Successor”), is a corporation or other legal entity organized and existing
under the laws of the United States or any state thereof or the District of Columbia, and the 

  
 - 15 - 








 
Successor assumes by supplemental indenture in a form reasonably satisfactory to the Trustee all of the obligations of the Company or the Guarantor, as the case may be, under the Securities or a
Guarantee, as the case may be, and the Indenture, and 
 (2) immediately after giving effect to such transaction, no Default
or Event of Default has occurred and is continuing. 
 The foregoing provisions shall not apply to: 

(A) the consolidation or merger of a Guarantor, or the sale, lease, conveyance or other disposition of all or substantially all
of the assets of a Guarantor, which under the provisions of Section 9.03 or the other provisions of this Indenture, results in such Guarantor being released from its Guarantee or the Successor not being required to become a Guarantor, as
the case may be, or 
 (B) a transaction the purpose of which is to change the state of incorporation of the Company or any
Guarantor. 
 Upon any such consolidation, merger, sale, lease, conveyance or other disposition, the Successor will be substituted for the
Company or the relevant Guarantor under the Indenture. The Successor may then exercise every power and right of the Company or the relevant Guarantor under this Indenture, and except in the case of a lease, the Company or the relevant Guarantor will
be released from all of its liabilities and obligations in respect of the Securities, the Guarantee and the Indenture. If the Company or a Guarantor leases all or substantially all of its assets the Company or such Guarantor will not be released
from its obligations to pay the principal of and interest, if any, on the Securities or the Guarantee, as applicable. 
 To the extent that
an Authorizing Resolution or supplemental indenture pertaining to any Series provides for different provisions relating to the subject matter of this Article Five, the provisions in such Authorizing Resolution or supplemental indenture
shall govern for purposes of such Series. 
 ARTICLE SIX 

DEFAULTS AND REMEDIES 

Section 6.01.    Events of Default. 

An “Event of Default” on a Series occurs if, voluntarily or involuntarily, whether by operation of law or otherwise, any of
the following occurs (except with respect to any Series of Securities for which the Authorizing Resolution or supplemental indenture under which such Series of Securities is issued or the form of Security for such Series expressly provides that any
such Event of Default shall not apply to such Series of Securities): 
  

	 	(1)	the failure by the Company to pay interest on any Security of such Series when the same becomes due and payable and the continuance of any such failure for a period of 30 days; 


 

	 	(2)	the failure by the Company to pay the principal of any Security of such Series when the same becomes due and payable at maturity, upon acceleration, redemption or otherwise; 


 

	 	(3)	the failure by the Company or any Restricted Subsidiary to comply with any of its agreements or covenants in, or provisions of, the Securities of such Series, the Guarantees (as they relate thereto) or this Indenture
(as they relate thereto) and such failure continues for the period and after the notice specified below (except in the case of a default with respect to Article Five (or any other provision specified in the applicable Authorizing
Resolution or supplemental indenture), which will constitute Events of Default with notice but without passage of time); 


  
 - 16 - 









	 	(4)	the Company or any Restricted Subsidiary that is a Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law: 

  

	 	(A)	commences a voluntary case, 

  

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

  

	 	(C)	consents to the appointment of a Custodian of it or for all or substantially all of its Property, or 

  

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

  

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

  

	 	(A)	is for relief against the Company or any Restricted Subsidiary that is a Significant Subsidiary as debtor in an involuntary case, 

  

	 	(B)	appoints a Custodian of the Company or any Restricted Subsidiary that is a Significant Subsidiary or a Custodian for all or substantially all of the Property of the Company or any Guarantor that is a Significant
Subsidiary, or 

  

	 	(C)	orders the liquidation of the Company or any Restricted Subsidiary that is a Significant Subsidiary, 


and the order or decree remains unstayed and in effect for 60 days; 
  

	 	(6)	any Guarantee of a Guarantor that is a Significant Subsidiary ceases to be in full force and effect (other than in accordance with the terms of such Guarantee and this Indenture) or is declared null and void and
unenforceable or found to be invalid or any Guarantor denies its liability under its Guarantee (other than by reason of release of a Guarantor from its Guarantee in accordance with the terms of this Indenture and the Guarantee); or


  

	 	(7)	any other Event of Default provided in the Authorizing Resolution or supplemental indenture under which such Series of Securities is issued or in the form of Security for such Series. 


A Default as described in subclause (3) above will not be deemed an Event of Default until the Trustee notifies the Company, or
the Holders of at least 25 percent in principal amount of the then outstanding Securities of the applicable Series notify the Company and the Trustee, of the Default and (except in the case of a default with respect to Article Five (or any
other provision specified in the applicable Authorizing Resolution or supplemental indenture)) the Company does not cure the Default within 60 days after receipt of the notice. The notice must specify the Default, demand that it be remedied and
state that the notice is a “Notice of Default.” If such a Default is cured within such time period, it ceases to exist, without any action by the Trustee or any other Person. 

Section 6.02.    Acceleration. 

If an Event of Default (other than an Event of Default with respect to the Company resulting from subclause (4) or
(5) above), shall have occurred and be continuing under the Indenture, the Trustee by notice to the Company, or the Holders of at least 25 percent in principal amount of the Securities of the applicable Series then outstanding by notice
to the Company and the Trustee, may declare all Securities of such Series to be due and payable immediately. Upon such declaration of acceleration, the amounts due and payable on the Securities of such Series will be due and payable immediately. If
an Event of Default with respect to the Company specified in subclauses (4) or (5) above occurs, all amounts due and payable on the Securities of such Series will ipso facto become and be immediately due and payable without
any declaration, notice or other act on the part of the Trustee and the Company or any Holder. 

  
 - 17 - 








 At any time after the principal of the Securities of such Series shall have been declared due and
payable, and before any judgment or decree for the payment of the amount due shall have been obtained or entered, the holders of a majority in aggregate principal amount of the then outstanding Securities of such Series, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its consequences if: (i) the Company has or has caused to be paid or deposited with the Trustee an amount sufficient to pay all matured installments of interest upon all the
Securities of such Series and the principal of any and all Securities of such Series that shall have become due otherwise than by acceleration, with interest upon such principal and, to the extent that such payment is enforceable under applicable
law, upon overdue installments of interest, at the rate expressed in the Securities of such Series to the date of such payment or deposit, and (ii) any and all Events of Default under this Indenture with respect to such Series, except
non-payment of the principal of, or interest on, any of the Securities of such Series as a result of such declaration, shall have been remedied or waived. 

No such rescission shall extend to or shall affect any subsequent Event of Default, or shall impair any right or power consequent thereon.

 Section 6.03.    Other Remedies. 

If an Event of Default on a Series occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to
collect the payment of principal of or interest on the Series or to enforce the performance of any provision in the Securities or this Indenture applicable to the Series. 

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 Securityholder 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. No remedy is exclusive
of any other remedy. All available remedies are cumulative. 
 Section 6.04.    Waiver of Existing Defaults. 

Subject to Section 10.02, the Holders of a majority in principal amount of the outstanding Securities of a Series on behalf of all
the Holders of the Series by notice to the Trustee may waive an existing Default on such Series and its consequences. When a Default is waived, it is cured and stops continuing, and any Event of Default arising therefrom shall be deemed to have been
cured; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 

Section 6.05.    Control by Majority. 

The Holders of a majority in principal amount of the outstanding Securities of a Series may 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 such Series. The Trustee, however, may refuse to follow any direction (i) that conflicts with law or this Indenture,
(ii) that, subject to Section 7.01, the Trustee determines is unduly prejudicial to the rights of other Securityholders, (iii) that would involve the Trustee in personal liability, if there shall be reasonable grounds for
believing that adequate indemnity against such liability is not reasonably assured to it, or (iv) if the Trustee shall not have been provided with indemnity satisfactory to it. 

Section 6.06.    Limitation on Suits. 

A Securityholder of a Series may not pursue any remedy with respect to this Indenture or the Series unless: 

 

	 	(1)	the Holder gives to the Trustee written notice of a continuing Event of Default on the Series; 

  

	 	(2)	the Holders of at least 25% in aggregate principal amount of the outstanding Securities of the Series make a written request to the Trustee to pursue the remedy; 


  
 - 18 - 









	 	(3)	such Holder or Holders offer to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; 

  

	 	(4)	the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and 

  

	 	(5)	no written request inconsistent with such written request shall have been given by the Holders of at least a majority in principal amount of the outstanding Securities of the Series to the Trustee. 


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. 
 Section 6.07.    Rights of Holders to
Receive Payment and Convert. 
 Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of
principal of, premium, if any, and interest on any Security, on or after the respective due dates expressed in the Security, or to bring suit for the enforcement of any such payment on or after such respective dates, is absolute and unconditional
and shall not be impaired or affected without the consent of the Holder. Notwithstanding anything to the contrary in this Indenture or the Securities, the right of any Holder of Securities to convert such Securities 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 in payment of interest or principal specified in Section 6.01(1) or (2) occurs 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 of principal and interest remaining unpaid. 

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 (including any claim for the reasonable compensation, expenses, disbursements, and advances of the Trustee, its agents and counsel) and the Securityholders allowed in any judicial proceedings relative to the Company, any Guarantor or their
respective creditors or Property, and unless prohibited by applicable law or regulation, may vote on behalf of the Holders in any election of a Custodian, and shall be entitled and empowered to collect and receive any moneys or other Property
payable or deliverable on any such claims and to distribute the same and any Custodian in any such judicial proceeding is hereby authorized by each Securityholder to make such payments to the Trustee. Nothing herein shall be deemed to authorize the
Trustee to authorize or consent to or vote for or accept or adopt on behalf of any Securityholder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder or to authorize the Trustee to
vote in respect of the claim of any Securityholder except as aforesaid for the election of the Custodian. 

Section 6.10.    Priorities. 

If the Trustee collects any money pursuant to this Article Six with respect to Securities of any Series, it shall pay out the money in
the following order: 
  

			
	 First:
	  	to the Trustee for amounts due under Section 7.07;


  
 - 19 - 









			
	 Second:
	  	to Securityholders of the Series for amounts due and unpaid on the Series for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Series for principal and
interest, respectively; and
		
	 Third:
	  	to the Company or the Guarantors as their interests may appear.

 The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this
Section 6.10. 
 Section 6.11.    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 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 the due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder pursuant to
Section 6.07 or a suit by Holders of more than 10% in principal amount of the Series. 
 ARTICLE SEVEN 

TRUSTEE 

Section 7.01.    Duties of Trustee. 

(a) If an Event of Default has occurred and is continuing with respect to Securities of any Series, the Trustee shall, prior to the receipt of
directions from the Holders of a majority in principal amount of the Securities of the Series, exercise its rights and powers 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: 

(1) The Trustee need perform only those duties that are specifically set forth in this Indenture and no others and no implied
covenants or obligations shall be read into this Indenture against the Trustee. 
 (2) 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. The
Trustee, however, in the case of certificates or opinion specifically required by any provision hereof to be furnished to it, 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 or matters stated therein.

the Trustee was negligent in ascertaining the pertinent facts.

action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 or any other direction of the Holders permitted hereunder.

liable for interest on any money received by it except as the Trustee may agree with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 

(g) None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial
liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there shall be reasonable grounds for believing that the repayment of such funds or adequate indemnity against such liability is not reasonably
assured to it. 
 Section 7.02.    Rights of Trustee. 

Subject to Section 7.01: 

(a) The Trustee may rely and shall be protected in acting or refraining from acting on any document, resolution, certificate, instrument,
report, or direction believed by it 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, resolution, certificate, instrument, report, or direction. 

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both, which
shall conform to Sections 12.04 and 12.05 hereof and containing such other statements as the Trustee reasonably deems necessary to perform its duties hereunder. The Trustee shall not be liable for any action it takes or omits to take
in good faith in reliance on the Officers’ Certificate, Opinion of Counsel or any other direction of the Company permitted hereunder. 

(c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care.

within the discretion or rights or powers conferred upon it by this Indenture. 
 (e) The Trustee may consult with counsel, and the written
advice of such counsel or any Opinion of Counsel as to matters of law shall be full and complete authorization and protection in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or

 (f) Unless otherwise specifically provided in the Indenture, any demand, request, direction or notice from the
Company or a Guarantor shall be sufficient if signed by an Officer of the Company or a Guarantor. 
 (g) For all purposes under this
Indenture, the Trustee shall not be deemed to have notice or knowledge of any Event of Default (other than under Section 6.01(1) or 6.01(2)) unless a Trust Officer assigned to and working in the Trustee’s corporate trust
office has actual knowledge thereof or unless written notice of any Event of Default is received by the Trustee at its address specified in Section 12.02 hereof and such notice references the Securities generally, the Company or this
Indenture. 
 (h) 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 Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which may be
incurred therein or thereby. 

  
 - 21 - 








 (i) The Trustee shall not be bound to make any investigation into the facts or matters stated in
any resolution, certificate (including any Officers’ Certificate), statement, instrument, opinion (including any Opinion of Counsel), notice, request, direction, consent, order, bond, debenture, or other paper or document, but the Trustee, in
its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit. 
 (j) The Trustee shall not be
required to give any bond or surety in respect of the performance of its powers and duties hereunder. 
 (k) The permissive rights of the
Trustee to do things enumerated in this Indenture shall not be construed as duties.

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 to each agent, custodian and other Person employed to
act hereunder. 
 (m) 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. 

(n) The Trustee may request that the Company deliver a certificate, the form of setting forth the names of individuals and/or titles of
officers authorized at such time to take specified actions pursuant to this Indenture. 
 (o) In order to comply with applicable tax laws
(inclusive of rules, regulations and interpretations promulgated by competent authorities) related to the Indenture in effect from time to time (“Applicable Law”) that a foreign financial institution, issuer, trustee, paying agent or other
party is or has agreed to be subject to, the Company agrees (i) to provide to the Trustee sufficient information about the parties and/or transactions (including any modification to the terms of such transactions) so that the Trustee can
determine whether they have tax related obligations under Applicable Law, (ii) that the Trustee shall be entitled to make any withholding or deduction from payments to the extent necessary to comply with Applicable Law for which the Trustee
shall not have any liability, and (iii) to hold harmless the Trustee for any losses it may suffer due to the actions it takes to comply with Applicable Law. 

The terms of this section shall survive the satisfaction and discharge of this Indenture. 

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 Guarantor or their affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. The Trustee, however, must comply with Sections 7.10 and 7.11.

accordance with any provision of this Indenture; it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee; and it shall not be responsible for any statement of the Company or any
Guarantor in this Indenture or in the Securities other than its certificate of authentication. 

  
 - 22 - 








 Section 7.05.    Notice of Defaults. 

If a Default on a Series occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to each Securityholder of the
Series notice of the Default (which shall specify any uncured Default known to it) within 90 days after it occurs. Except in the case of a default in payment of principal of or interest on a Series, the Trustee may withhold the notice if and so long
as the board of directors of the Trustee, the executive or any trust committee of such directors and/or responsible officers of the Trustee in good faith determine(s) that withholding the notice is in the interests of Holders of the Series. 

Section 7.06.    Reports by Trustee to Holders. 

Within 60 days after each May 15 beginning with the May 15 following the date of this Base Indenture, the Trustee shall mail to each
Securityholder a brief report dated as of such May 15 that complies with TIA § 313(a) (but if no event described in TIA § 313(1) through (8) has occurred within the twelve months preceding the reporting date no report in relation
thereto need be transmitted). The Trustee also shall comply with TIA § 313(b). 
 A copy of each report at the time of its mailing to
Securityholders shall be delivered to the Company and filed by the Trustee with the SEC and each national securities exchange on which the Securities are listed. The Company agrees to notify the Trustee of each national securities exchange on which
the Securities are listed. 
 Section 7.07.    Compensation and Indemnity. 

The Company shall pay to the Trustee from time to time reasonable compensation for its services subject to any written agreement between the
Trustee and the Company. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred by it. Such expenses shall include the reasonable compensation and expenses of the Trustee’s agents and counsel.
The Company and any Guarantors, jointly and severally, shall indemnify each of the Trustee or any predecessor Trustee and its agents, employees, officers, stockholders and directors for, and hold them harmless against, any and all loss, damage,
claims including taxes (other than taxes based upon, measured by or determined by the income of the Trustee), liability or expense incurred by them except for such actions to the extent caused by any negligence, bad faith or willful misconduct on
their part, arising out of or in connection with the acceptance or administration of this trust including the reasonable costs and expenses of defending themselves against or investigating any claim or liability in connection with the exercise or
performance of any of the Trustee’s rights, powers or duties hereunder. The Trustee shall notify the Company promptly of any claim asserted against the Trustee or any of its agents, employees, officers, stockholders and directors of which a
Trust Officer has received notice for which it may seek indemnity. The Company may, subject to the approval of the Trustee (which approval shall not be unreasonably withheld), defend the claim and the Trustee shall cooperate in the defense. The
Trustee and its agents, employees, officers, stockholders and directors subject to the claim may have one firm of separate counsel (plus, with the prior written consent of the Company (not to be unreasonably withheld) and upon the reasonable request
by the Trustee to the Company, a second firm of separate counsel) at any one time and the Company shall pay the reasonable fees and expenses of such counsel; provided, however, that the Company will not be required to pay such fees and
expenses if, subject to the approval of the Trustee (which approval shall not be unreasonably withheld), it assumes the Trustee’s defense and there is no conflict of interest between the Company, on the one hand, and the Trustee and its agents,
employees, officers, stockholders and directors subject to the claim, on the other hand, in connection with such defense as reasonably determined by the Trustee. The Company need not pay or indemnify for any settlement made without its written
consent (which consent shall not be unreasonably withheld). The Company need not reimburse any expense or indemnify against any loss, damage, claim, liability or expense to the extent caused by any negligence, bad faith or willful misconduct of the
Trustee, any predecessor Trustee, or any of their respective employees, officers, stockholders or directors. 
 Unless otherwise provided in
any supplemental indenture or Authorizing Resolution relating to any Series, to ensure the Company’s payment obligations in this Section, the Trustee shall have a claim prior to the Securities of all Series on all money 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 or in
connection with Article Six hereof, 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. 


  
 - 23 - 








 Section 7.08.    Replacement of Trustee. 

The Trustee may resign with respect to Securities of any or all Series by so notifying the Company. The Holders of a majority in principal
amount of the outstanding Securities (or of the relevant Series) may remove the Trustee by so notifying the removed Trustee in writing and may appoint a successor trustee with the Company’s consent. Such resignation or removal shall not take
effect until the appointment by the Securityholders of the relevant Series or the Company as hereinafter provided of a successor trustee and the acceptance of such appointment by such successor trustee. The Company may remove the Trustee and any
Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee for any or no reason, including if: 
  

	 	(1)	the Trustee fails to comply with Section 7.10 after written request by the Company or any bona fide Securityholder who has been a Securityholder for at least six months; 


 

	 	(2)	the Trustee is adjudged a bankrupt or an insolvent; 

  

	 	(3)	a receiver or other public officer takes charge of the Trustee or its Property; or 

  

	 	(4)	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 with respect to the Securities of the relevant Series. If a successor trustee does not take office within 45 days after the retiring Trustee
resigns or is removed, the retiring Trustee, the Company or any Holder may petition any court of competent jurisdiction for 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. Immediately after that,
the retiring Trustee shall transfer all Property held by it as Trustee to the successor trustee, 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. A successor trustee shall mail notice of its succession to each Securityholder. 
 Any successor trustee
appointed pursuant to this Section 7.08 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.

 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 Trustee shall be responsible for any act or failure to act on the part of any other
Trustee hereunder. 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, and such retiring Trustee shall have no further
responsibility with respect to the Securities of that

or those Series to which the appointment of such successor trustee relates for the exercise of rights and powers or for the performance of the duties and obligations vested in the Trustee under
this Indenture. 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. On request of the Company or any successor trustee, such retiring Trustee shall assign, transfer and deliver to such successor trustee, to the extent contemplated by such supplemental indenture, the
property and funds 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. 

Section 7.09.    Successor Trustee by Merger, etc.

 ARTICLE EIGHT 

DISCHARGE OF INDENTURE 

Section 8.01.    Defeasance or Satisfaction upon Deposit of Moneys or Government Obligations. 

(a) The Company may, at its option and at any time, elect to have either paragraph (b) or paragraph (c) below be
applied to the outstanding Securities of any Series upon compliance with the applicable conditions set forth in paragraph (d). 
 (b)
Upon the Company’s exercise under paragraph (a) of the option applicable to this paragraph (b) with respect to any Series, the Company and the Guarantors shall be deemed to have been released and discharged from their
respective obligations with respect to the outstanding Securities of the Series on the date the applicable conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means
that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Securities of a Series, which shall thereafter be deemed to be “outstanding” only for the purposes of the Sections and
matters under this Indenture referred to in (i) and (ii) below, and the Company and the Guarantors shall be deemed to have satisfied all their other obligations under such Securities and this Indenture insofar as such Securities are
concerned, except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of outstanding Securities of a Series to receive solely from the trust fund described in paragraph
(d) below and as more fully set forth in such paragraph, payments in respect of the principal of and interest on such Securities when such payments are due and (ii) obligations listed in Section 8.02, subject to compliance
with this Section 8.01. The Company may exercise its option under this paragraph (b) with respect to a Series notwithstanding the prior exercise of its option under paragraph (c) below with respect to the
Securities of the Series. 
 (c) Upon the Company’s exercise under paragraph (a) of the option applicable to this
paragraph (c) with respect to a Series, the Company and the Guarantors shall be released and discharged from the obligations under any covenant contained in Article Five and any other covenant contained in or referenced in the
Authorizing 

  
 - 25 - 








 
Resolution or supplemental indenture relating to such Series (to the extent such release and discharge shall not be prohibited thereby), on and after the date the conditions set forth below are
satisfied (hereinafter, “Covenant Defeasance”), and the Securities of such Series shall thereafter be deemed to be not “outstanding” for the purpose of any direction, waiver, consent or declaration or act of Holders (and
the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder. For this purpose, such Covenant Defeasance means that, with respect to the outstanding
Securities of a Series, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01(3) or
otherwise, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby. 
 (d) The
following shall be the conditions to application of either paragraph (b) or paragraph (c) above to the outstanding Securities of the applicable Series: 

(1) The Company shall have irrevocably deposited in trust with the Trustee (or another qualifying trustee), pursuant to an
irrevocable trust and security agreement in form and substance reasonably satisfactory to the Trustee, money in the currency in which the Securities of such Series are payable or Government Obligations or a combination thereof in such amounts and at
such times as are sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of and interest on the outstanding Securities of such Series to maturity or redemption; provided,
however, that the Trustee (or other qualifying trustee) shall have received an irrevocable written order from the Company instructing the Trustee (or other qualifying trustee) to apply such money or the proceeds of such Government Obligations
to said payments with respect to the Securities of such Series to maturity or redemption; 
 (2) No Default or Event of
Default (other than a Default or Event of Default resulting from non-compliance with any covenant from which the Company and the Guarantors are released upon effectiveness of such Legal Defeasance or Covenant Defeasance pursuant to paragraph
(b) or (c) hereof, as applicable) shall have occurred and be continuing on the date of such deposit or result therefrom; 

(3) (i) In the event the Company elects paragraph (b) hereof, the Company shall deliver to the Trustee an Opinion
of Counsel in the United States, in form and substance reasonably satisfactory to the Trustee, to the effect that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the
Issue Date pertaining to such Series, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall state that, or (ii) in the event the Company elects
paragraph (c) hereof, the Company shall deliver to the Trustee an Opinion of Counsel in the United States, in form and substance reasonably satisfactory to the Trustee, to the effect that, in the case of clauses (i) and
(ii), and subject to customary assumptions and exclusions, Holders of the Securities of such Series will not recognize income, gain or loss for federal income tax purposes as a result of such deposit and the defeasance contemplated hereby and
will be subject to federal income tax in the same amounts and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred; 

(4) The Company shall have delivered to the Trustee an Officers’ Certificate, stating that the deposit under clause
(1) was not made by the Company with the intent of preferring the Holders of the Securities of such Series over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the
Company or any Guarantor or others; 
 (5) Notwithstanding any other provisions of this Section 8.01, such legal
defeasance or covenant defeasance shall be effected in compliance with any additional or substitute terms, conditions or limitations which may be imposed on the Company on any outstanding Securities of an applicable Series pursuant to
Section 2.01; and 

  
 - 26 - 








 (6) The Company has delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each stating that all conditions precedent specified herein relating to the defeasance contemplated by this Section 8.01 have been complied with. 

In the event all or any portion of the Securities of a Series are to be redeemed through such irrevocable trust, the Company must make
arrangements satisfactory to the Trustee, at the time of such deposit, for the giving of the notice of such redemption or redemptions by the Trustee in the name and at the expense of the Company. 

(e) In addition to the Company’s rights above under this Section 8.01, the Company may terminate all of its obligations under
this Indenture with respect to a Series, and the obligations of the Guarantors shall terminate with respect to such Series (subject to Section 8.02), when: 

(1) All Securities of such Series theretofore authenticated and delivered (other than Securities which have been destroyed,
lost or stolen and which have been replaced or paid as provided in Section 2.07 and Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the
Company or discharged from such trust) have been delivered to the Trustee for cancellation or all such Securities not theretofore delivered to the Trustee for cancellation (A) have become due and payable, (B) will become due and payable at
maturity within one year or (C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and in each
such case, the Company has irrevocably deposited or caused to be deposited with the Trustee (or another qualifying trustee) as trust funds in trust solely for that purpose an amount of money in the currency in which the Securities of such Series are
payable or Government Obligations or a combination thereof sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay and discharge the entire Indebtedness on the Securities of such Series not theretofore
delivered to the Trustee for cancellation, for principal of and interest on the Securities of such Series, on the date of such deposit or to the maturity or redemption date, as the case may be; 

(2) The Company has paid or caused to be paid all other sums payable hereunder by the Company; 

(3) The Company has delivered irrevocable instructions to the Trustee (or such other qualifying trustee), to apply the
deposited money toward the payment of the Securities of such Series at maturity or redemption, as the case may be; and 
 (4)
The Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, stating that all conditions precedent specified in this Section 8.01(e) relating to the satisfaction and discharge of this Indenture have
been complied with. 
 Section 8.02.    Survival of the Company’s Obligations. 

Notwithstanding the satisfaction and discharge of this Indenture under Section 8.01, the Company’s obligations in Paragraph
8 of the Securities and Sections 2.03 through 2.07, 4.01, 7.07, 7.08, 8.04 and 8.05 of this Indenture, however, shall survive until the Securities of an applicable Series are no longer
outstanding. Thereafter, the Company’s obligations in Paragraph 8 of the Securities of such Series and Sections 7.07, 8.04 and 8.05 of this Indenture shall survive (as they relate to such Series). 

Section 8.03.    Application of Trust Money. 

The Trustee shall hold in trust money or Government Obligations deposited with it pursuant to Section 8.01. It shall apply the
deposited money and the money from Government Obligations in accordance with this Indenture to the payment of principal of and interest on the Securities of the defeased Series. 

  
 - 27 - 








 Section 8.04.    Repayment to the Company. 

The Trustee and the Paying Agent shall promptly pay to the Company upon request any excess money or securities held by them at any time. The
Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal or interest that remains unclaimed for two years, provided, however, that the Trustee or such Paying Agent, before
being required to make any such repayment, may at the expense of the Company cause to be published once in a newspaper of general circulation in the City of New York or mail to each such Holder notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the date of such publication or mailing, any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Securityholders
entitled to the money must look to the Company or any Guarantor for payment as general creditors unless applicable abandoned property law designates another person and all liability of the Trustee or such Paying Agent with respect to such money
shall cease. 
 Section 8.05.    Reinstatement. 

If the Trustee is unable to apply any money or Government Obligations in accordance with Section 8.01 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 Company’s and each Guarantor’s obligations under this Indenture and the
Securities relating to the Series shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.01 until such time as the Trustee is permitted to apply all such money or Government Obligations in accordance with
Section 8.01; provided, however, that (a) if the Company or any Guarantor has made any payment of interest on or principal of any Securities of the Series because of the reinstatement of its obligations hereunder, the
Company or Guarantor shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or Government Obligations held by the Trustee and (b) unless otherwise required by any legal proceeding or any order
or judgment of any court or governmental authority, the Trustee shall return all such money or Government Obligations to the Company promptly after receiving a written request therefor at any time, if such reinstatement of the Company’s or
Guarantor’s obligations has occurred and continues to be in effect. 
 ARTICLE NINE 

GUARANTEES 

Section 9.01.    Unconditional Guarantees. 

Subject to any other provisions set forth in the Authorizing Resolution or supplemental indenture relating to a particular Series, each
Guarantor unconditionally, jointly and severally, guarantees (each such guarantee to be referred to herein as the “Guarantee”) to each Holder of Securities of such Series authenticated and delivered by the Trustee and to the Trustee
and its successors and assigns, that: (i) the principal of and interest on the Securities of such Series will be promptly paid in full when due, subject to any applicable grace period, whether at maturity, by acceleration or otherwise and
interest on the overdue principal, if any, and interest on any interest of the Securities of such Series and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder, except obligations to pay principal of and
interest on any other Series not so guaranteed, will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Securities of such Series or
of any such other obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at stated maturity, by acceleration or otherwise,
subject, however, in the case of clauses (i) and (ii) above, to the limitations set forth in Section 9.04. Each Guarantor agrees that its obligations hereunder shall be unconditional, irrespective of the validity,
regularity or enforceability of the Securities of such Series or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Securities of such Series with respect to any provisions hereof or thereof,
the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor waives diligence, presentment,
demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that, subject to
Section 9.03, this Guarantee will not be discharged except by complete performance of the obligations contained in the Securities of the 

  
 - 28 - 








 
applicable Series, this Indenture and in this Guarantee. If any Holder or the Trustee is required by any court or otherwise to return to the Company, any Guarantor, or any custodian, trustee,
liquidator or other similar official acting in relation to the Company or any Guarantor, any amount paid by the Company or any Guarantor to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full
force and effect. Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in
Article Six for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such
obligations as provided in Article Six, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of this Guarantee. 

Section 9.02.    Severability. 

In case any provision of this Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby. 
 Section 9.03.    Release of a Guarantor. 

Notwithstanding anything in this Indenture to the contrary, in the event of (i) the sale or other disposition of Capital Stock of any
Guarantor if as a result of such disposition, such Person ceases to be a Restricted Subsidiary of the Company, (ii) a sale or other disposition of all or substantially all of the assets of any Guarantor (other than to the Company or another
Guarantor), (iii) a merger or consolidation of a Guarantor with a Person other than the Company or another Guarantor, (iv) a Guarantor ceasing to guarantee any Indebtedness of the Company, or (v) the designation of a Restricted
Subsidiary that is a Guarantor as an Unrestricted Subsidiary, then such Guarantor (in the case of clauses (i), (ii), (iv) and (v) above) will be automatically and unconditionally released and discharged from all obligations under this
Article Nine, the other provisions of this Indenture and the Securities and the Person acquiring such assets (in the case of clauses (ii) and (iii) above) shall not be required to assume the Guarantor’s obligations under this
Article Nine, the other provisions of this Indenture and the Securities or otherwise become a Guarantor, in each case without any further action required on the part of the Trustee, any Holder, the Company or any Guarantor; provided
that such sale, disposition or other transaction is otherwise in compliance with this Indenture. 
 Nothing contained in this Indenture or
in any of the Securities shall prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or shall prevent any sale, lease, conveyance or other disposition of all or substantially assets of a Guarantor to the
Company or another Guarantor. Upon any such consolidation, merger, or disposition, the Guarantee given by such Guarantor shall no longer have any force or effect. 

The Trustee shall deliver an appropriate instrument evidencing any such release upon receipt of a request by the Company accompanied by an
Officers’ Certificate and Opinion of Counsel certifying as to the compliance with this Section 9.03. 
 Any Guarantor not
released in accordance with this Section 9.03 remains liable for the full amount of principal of and interest on the Securities as provided in this Article Nine, except as provided in Article Eight. 

Section 9.04.    Limitation of a Guarantor’s Liability. 

Each Guarantor and by its acceptance hereof each Holder confirms that it is the intention of all such parties that the guarantee by such
Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar Federal or state law. To effectuate
the foregoing intention, the Holders and such Guarantor irrevocably agree that the obligations of such Guarantor under the Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of
such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to Section 9.05, result in the
obligations of such Guarantor under the Guarantee not constituting such fraudulent transfer or conveyance. 

  
 - 29 - 








 Section 9.05.    Contribution. 

In order to provide for just and equitable contribution among the Guarantors, the Guarantors agree, inter se, that in the event any payment or
distribution is made by any Guarantor (a “Funding Guarantor”) under the Guarantee, such Funding Guarantor shall be entitled to a contribution from all other Guarantors in a pro rata amount based on the Adjusted Net Assets of each
Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Company’s obligations with respect to any Securities or any other Guarantor’s obligations with respect
to its Guarantee. “Adjusted Net Assets” of such Guarantor at any date shall mean the lesser of the amount by which (x) the fair value of the Property of such Guarantor exceeds the total amount of liabilities, including
contingent liabilities (after giving effect to all other fixed and contingent liabilities incurred or assumed on such date and after giving effect to any collection from any other Subsidiary of the Guarantor in respect of the obligations of its
Guarantee), but excluding liabilities under the Guarantee, of such Guarantor at such date and (y) the present fair salable value of the assets of such Guarantor at such date exceeds the amount that will be required to pay the probable liability
of such Guarantor on its debts (after giving effect to all other fixed and contingent liabilities incurred or assumed on such date and after giving effect to any collection from any other Subsidiary of the Company in respect of the obligations of
such Guarantor under its Guarantee), excluding debt in respect of the Guarantee of such Guarantor, as they become absolute and matured. 

Section 9.06.    Waiver of Subrogation. 

Until all guaranteed obligations under this Indenture and with respect to all Securities of an applicable Series are paid in full, each
Guarantor irrevocably waives any claim or other rights which it may now or hereafter acquire against the Company that arise from the existence, payment, performance or enforcement of such Guarantor’s obligations under the Guarantee and this
Indenture, including any right of subrogation, reimbursement, exoneration, indemnification, and any right to participate in any claim or remedy of any Holder of Securities of the applicable Series against the Company, whether or not such claim,
remedy or right arises in equity, or under contract, statute or common law, including the right to take or receive from the Company, directly or indirectly, in cash or other Property or by set-off or in any other manner, payment or security on
account of such claim or other rights. If any amount shall be paid to any Guarantor in violation of the preceding sentence and the Securities of the applicable Series shall not have been paid in full, such amount shall have been deemed to have been
paid to such Guarantor for the benefit of, and held in trust for the benefit of, the Holders of the Securities of the applicable Series, and shall forthwith be paid to the Trustee for the benefit of such Holders to be credited and applied upon the
Securities of the applicable Series, whether matured or unmatured, in accordance with the terms of this Indenture. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this
Indenture and that the waiver set forth in this Section 9.06 is knowingly made in contemplation of such benefits. 

Section 9.07.    Execution of Guarantee. 

To evidence their guarantee to the Holders set forth in this Article Nine with respect to any Series, the Guarantors shall execute the
Guarantee in substantially the form included in Exhibit A or in any such other form set forth in the Authorizing Resolution or supplemental indenture pertaining to the applicable Series, which shall be endorsed on each Security ordered to be
authenticated and delivered by the Trustee. Each Guarantor agrees that its Guarantee set forth in this Article Nine shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation of such Guarantee.
Each such Guarantee shall be signed on behalf of each Guarantor by one Officer (who shall, in each case, have been duly authorized by all requisite corporate or other actions) shall attest to such Guarantee prior to the authentication of the
Security on which it is endorsed, and the delivery of such Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of such Guarantee on behalf of such Guarantor. Such signature upon the Guarantee may be by
manual or facsimile signature of such officer and may be imprinted or otherwise reproduced on the Guarantee, and in case any such officer who shall have signed the Guarantee shall cease to be such officer before the Security on which such Guarantee
is endorsed shall have been authenticated and delivered by the Trustee or disposed of by the Company, such Security nevertheless may be authenticated and delivered or disposed of as though the person who signed the Guarantee had not ceased to be
such officer of the Guarantor.

 After an amendment under this Section 10.01 becomes effective, the Company shall mail

 Section 10.02.    With Consent of Holders. 

The Company, the Guarantors and the Trustee may amend or supplement this Indenture or the Securities of a Series without notice to any
Securityholder of such Series but with the written consent of the Holders of at least a majority in principal amount of the outstanding Securities of such Series (including consents obtained in connection with a purchase of, or tender offer or
exchange offer for, Securities of such Series). Each such Series shall vote as a separate class. The Holders of a majority in principal amount of the outstanding Securities of any Series may waive compliance by the Company with any provision of the
Securities of such Series or of this Indenture relating to such Series without notice to any Securityholder (including any waiver granted in connection with a purchase of, or tender offer or exchange offer for, Securities of such Series). Without
the consent of each Holder of a Security the terms of which are directly amended, supplemented or waived, however, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may not: 

 

	 	(1)	reduce the amount of Securities of the relevant Series whose Holders must consent to an amendment, supplement or waiver; 

  

	 	(2)	reduce the rate of or extend the time for payment of interest, including defaulted interest, on any Security; 

  

	 	(3)	reduce the principal of or extend the fixed maturity of any Security or alter the provisions (including related definitions) with respect to redemption of any Security pursuant to Article Three hereof or with

Security; 

  

	 	(5)	modify the ranking or priority of the Securities of the relevant Series or any Guarantee thereof; 

  

	 	(6)	release any Guarantor from any of its obligations under its Guarantee or this Indenture otherwise than in accordance with the terms of this Indenture; 


 

	 	(7)	make any change in Sections 6.04, 6.07 or this Section 10.02, except to increase the percentage required for modification or waiver or to provide for consent of each affected Holder of
Securities of such Series; 

  

	 	(8)	waive a continuing Default or Event of Default in the payment of the principal of or interest on any Security; or 

  

	 	(9)	make any Security payable at a place or in money other than that stated in the Security, or impair the right of any Securityholder to bring suit as permitted by Section 6.07. 


An amendment of a provision included solely for the benefit of one or more Series does not affect the interests of Securityholders of any
other Series. 
 It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed
supplement, but it shall be sufficient if such consent approves the substance thereof. 

  
 - 32 - 








 Section 10.03.    Compliance with Trust Indenture Act. 

Every amendment to or supplement of this Indenture or any Securities shall comply with the TIA as then in effect. 

Section 10.04.    Revocation and Effect of Consents. 

A consent to an amendment, supplement or waiver by a Holder shall bind 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. Unless otherwise provided in the consent or the consent solicitation statement or other document describing
the terms of the consent, any Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security. Any revocation of a consent by the Holder of a Security or any such subsequent Holder shall be effective only if the
Trustee receives the notice of revocation before the date on which the Trustee receives an Officers’ Certificate from the Company certifying that the requisite number of consents have been received. 

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders of Securities of any Series
entitled to consent to any amendment, supplement or waiver, which record date shall be at least 10 days prior to the first solicitation of such consent. If a record date is fixed, and if Holders otherwise have a right to revoke their consent under
the consent or the consent solicitation statement or other document describing the terms of the consent, then notwithstanding the second to last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or
their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 90
days after such record date. 
 An amendment, supplement or waiver with respect to a Series becomes effective upon the (i) receipt by
the Company or the Trustee of the requisite consents, (ii) satisfaction of any conditions to effectiveness as set forth in this Indenture or any indenture supplemental hereto containing such amendment, supplement or waiver and
(iii) execution of such amendment, supplement or waiver (or the related supplemental indenture) by the Company and the Trustee. After an amendment, supplement or waiver with respect to a Series becomes effective, it shall bind every Holder of
such Series, unless it makes a change described in any of clauses (1) through (9) of Section 10.02, in which case, the amendment, supplement or waiver shall bind a Holder of a Security of such Series only if it
has consented to such amendment, supplement or waiver and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security; provided that no such waiver shall impair or
affect the right of any Holder to receive payment of principal of and interest on a Security, on or after the respective due dates expressed in such Security, or to bring suit for the enforcement of any such payment on or after such respective dates
without the consent of such Holder. 
 Section 10.05.    Notation on or Exchange of Securities. 

If an amendment, supplement or waiver changes the terms of a Security, the Company may require the Holder of the Security to deliver it to the
Trustee, at which time the Trustee shall place an appropriate notation on the Security about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee 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 10.06.    Trustee to Sign
Amendments, etc. 
 Subject to Section 7.02(b), the Trustee shall sign any amendment, supplement or waiver authorized
pursuant to this Article if the amendment, supplement or waiver does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing or refusing to sign such amendment
or supplemental indenture, the Trustee shall be entitled to receive and shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that such amendment, supplement or waiver is authorized
or permitted by this Indenture and (solely with respect to such Opinion of Counsel) that it will be valid and binding upon the Company and any Guarantors in accordance with its terms.

and The Bank of New York Mellon Trust Company, N.A., as trustee (in such capacity, the “Trustee”), to which reference is hereby made for a statement of the respective rights, obligations, duties and immunities thereunder of the
Company, the Trustee and the Holders and of the terms upon which the Securities are, and are to be, authorized and delivered. All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them therein.

 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 semiannually on             and             of each
year, commencing             ,         , until the principal is paid or made available for payment. Interest on the Securities will accrue from the
most recent date to which interest has been paid or duly provided for or, if no interest has been paid, from             ,         , provided
that, if there is no existing default in the payment of interest, and if this Security is authenticated between a record date referred to on the face hereof and the next succeeding interest payment date, interest shall accrue from such interest
payment date. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
  

	2.	Method of Payment. 

 The Company will pay interest on the Securities (except
defaulted interest, if any, which will be paid on such special payment date to Holders of record on such special record date as may be fixed by the Company) to the persons who are registered Holders of Securities at the close of business on the
[Insert record dates] immediately preceding the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of [Insert applicable country or currency]
that at the time of payment is legal tender for payment of public and private debts. 
  

	3.	Paying Agent and Registrar.

redemption date to each Holder of Securities to be redeemed at its registered address. Securities in denominations larger than
            2 may be redeemed in part. On and after the redemption date interest ceases to accrue on Securities or portions of them
called for redemption, provided that if the Company shall default in the payment of such Securities at the redemption price together with accrued interest, interest shall continue to accrue at the rate borne by the Securities. 

 

	5.	Mandatory Redemption.3 

 The
Company shall redeem [    ]% of the aggregate principal amount of Securities originally issued under the Indenture on each of [            ], which redemptions are
calculated to retire [    ]% of the Securities originally issued prior to maturity. Such redemptions shall be made at a redemption price equal to 100% of the principal amount thereof, together with accrued interest to the
redemption date. The Company may reduce the principal amount of Securities to be redeemed pursuant to this Paragraph 5 by the principal amount of any Securities previously redeemed, retired or acquired, otherwise than pursuant to this
Paragraph 5, that the Company has delivered to the Trustee for cancellation and not previously credited to the Company’s obligations under this Paragraph 5. Each such Security shall be received and credited for such purpose by the
Trustee at the redemption price and the amount of such mandatory redemption payment shall be reduced accordingly. 
  

	6.	Denominations, Transfer, Exchange. 

 The Securities are in registered form only
without coupons in denominations of             4 and integral multiples of
            in excess thereof.5 A Holder may transfer or exchange Securities by presentation of such Securities to the Registrar or a
co-Registrar with a request to register the transfer or to exchange them for an equal principal amount of Securities of other denominations. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer
documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not transfer or exchange any Security selected for redemption or purchase, except the unredeemed or unpurchased part thereof if the Security is
redeemed or purchased in part, or transfer or exchange any Securities for a period of 15 days before a selection of Securities to be redeemed or purchased. 
  

	7.	Persons Deemed Owners. 

 The registered Holder of this Security shall be treated
as the owner of it for all purposes. 
  

	8.	Unclaimed Money. 

 Subject to any applicable abandoned property law, the Trustee
and the Paying Agent shall pay to the Company upon written request any money held by them for the payment of principal or interest that remains unclaimed for two years, and thereafter, Holders entitled to the money must look to the Company for

the Securities may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the outstanding Securities of such Series and any past default or compliance with any provision relating to any Series of the
Securities may be waived in a particular instance with the consent of the Holders of a majority in principal amount of the outstanding Securities of such Series.6 Without the consent of any
Securityholder, the Company and the Trustee may amend or supplement the Indenture or the Securities in certain respects as specified in the Indenture. 
  

	10.	Successor Corporation. 

 When a successor corporation assumes all the obligations
of its predecessor under the Securities and the Indenture, the predecessor corporation will be released from those obligations. 
  

	11.	Trustee Dealings With Company. 

 Subject to certain limitations imposed by the
TIA, the Trustee under the Indenture, 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, including owning or pledging the Securities. 
  

	12.	No Recourse Against Others. 

 A director, officer, employee or stockholder, as
such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder by accepting a
Security waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. The waiver may not be effective to waive liabilities under the federal securities laws. 

 

	13.	Discharge of Indenture. 

 The Indenture contains certain provisions pertaining to
defeasance, satisfaction and discharge, which provisions shall for all purposes have the same effect as if set forth herein. 
  

	14.	Authentication. 

 This Security shall not be valid until an authorized signatory
of the Trustee signs the certificate of authentication on the other side of this Security.
