 - 13 -









 
one series need not be issued at the same time and, unless otherwise provided, a series may be reopened, without the consent of the Holders, for issuances of additional Securities of such series.

 Section 2.03. PAYMENT OF INTEREST 
 Except as otherwise specified in any Security issued hereunder, or in any supplemental indenture with respect to Securities of a particular series, interest shall be due and payable on a Security as
follows: 
 (a) A Holder of such Security as of the close of business on a Regular Record Date shall be entitled to receive and
shall receive (except as otherwise indicated in this Section 2.03), accrued and unpaid interest on such Security from the date specified in such Security to the Interest Payment Date next succeeding such Regular Record Date, other than any
Security whose Maturity Date is prior to such Interest Payment Date. 
 (b) In the event that a Security of any series becomes
subject to redemption pursuant to Article 3 and the redemption date occurs after a Regular Record Date but on or prior to the next succeeding Interest Payment Date, the person whose Security becomes subject to redemption (and only such Person rather
than the Holder as of such Regular Record Date) shall be entitled to receive and shall receive accrued and unpaid interest from the preceding Interest Payment Date (or such earlier date on which interest was last paid) to, but excluding, the
redemption date of such Security, even if such Person is not the Holder of such Security on the Regular Record Date. In the event that a Security of any series becomes subject to redemption pursuant to Article 3 and the redemption date occurs on an
Interest Payment Date, the Holder as of the Regular Record Date corresponding to such Interest Payment Date shall be entitled to receive and shall receive accrued and unpaid interest from the preceding Interest Payment Date (or such earlier date on
which interest was last paid or as otherwise provided in the Security) to, but excluding, the redemption date of such Security, even if such Person is not the Holder of such Security. 

(c) The Company shall pay the principal of and interest on any Global Security registered in the name of or held by the Depositary or its
nominee in immediately available funds to the Depositary or its nominee, as the case may be, as the registered Holder of such Global Security. The Company shall pay the principal of any Physical Securities at the office or agency designated by the
Company for that purpose. 
 (d) The Company shall pay interest on any Physical Securities (A) to Holders having an
aggregate principal amount of $10,000,000 or less, by check mailed to the Holders of such Securities at their address as it appears in the Security Register and (B) to Holders having an aggregate principal amount of more than $10,000,000,
either by check mailed to each such Holder or, upon application by a Holder to the Registrar not later than the relevant Regular Record Date, by wire transfer in immediately available funds to that Holder’s account within the United States,
which application shall remain in effect until the Holder notifies the Registrar, in writing, to the contrary. 

  
 - 14 -









 (e) In the event that Securities of any series are convertible and if, in such case, a
Security is converted pursuant to Article 12, the Holder who converts such Security on any date other than an Interest Payment Date (except in the case of a Security whose Maturity Date is after the immediately preceding Record Date but prior to
such Interest Payment Date) shall not be entitled to receive unpaid interest on such Security from the preceding Interest Payment Date until the conversion date, such amounts being deemed to have been paid by receipt of shares of Common Stock in
full rather than canceled, extinguished or forfeited. As a result, if a Security is converted between a Regular Record Date and an Interest Payment Date (but not including on the Interest Payment Date), the Holder of record on the Regular Record
Date will receive accrued and unpaid interest on such Security for such period on such Interest Payment Date but the Holder which converts the Security will be required to remit to the Company an amount equal to that interest at the time such Holder
surrenders the Security for conversion, pursuant to Article 12; provided, however, that such Holder will not be required to remit such interest if (1) the Company has specified a redemption date that occurs during the period from the
close of business on a Regular Record Date to the close of business on the Business Day immediately preceding the Interest Payment Date to which such record date relates or (2) any overdue interest exists on the Conversion Date with respect to
the Securities converted, but only to the extent of overdue interest. 
 Section 2.04. DENOMINATIONS. 

Unless otherwise specified in any Security issued hereunder or in any supplemental indenture, Securities of a series denominated in U.S.
dollars shall be issuable in denominations of U.S. $1,000 and any integral multiple thereof. Securities denominated in a foreign currency shall be issuable in such denominations as are established with respect to such Securities in or pursuant to
this Indenture. 
 Section 2.05. EXECUTION AND AUTHENTICATION. 
 An Officer shall sign the Securities for the Company by manual or facsimile signature. 
 If an Officer whose signature is on a Security no longer holds that office at the time a Security is authenticated, the Security shall nevertheless be valid. 

A Security shall not be valid until authenticated by the manual signature of the Trustee (or its authenticating agent as provided below).
The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. 
 The Trustee shall,
upon a written order of the Company signed by an Officer (an “Authentication Order”), together with an Officers’ Certificate and an Opinion of Counsel, authenticate Securities for original issue in the aggregate principal
amount stated in the Authentication Order. The Officers’ Certificate and Opinion of Counsel shall each state that all conditions precedent provided for or relating to the issuance of such Securities have been complied with. 

If all of the Securities of a series are not to be originally issued at the same time, then the documents required to be delivered
pursuant to this Section 2.05 must be delivered only once, prior to the authentication and delivery of the first Security of such series; provided, however,  

  
 - 15 -









 
that any subsequent request by the Company to the Trustee to authenticate additional Securities of such series upon original issuance shall constitute a representation and warranty by the Company
that, as of the date of such request, the statements made in the Officers’ Certificate delivered pursuant to this Section 2.05 shall be true and correct as if made on such date and that all the conditions precedent, if any, provided for in
this Indenture or the terms of the Securities of such series relating to the authentication and delivery of additional Securities of such series have been complied with. 
 The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in
this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company. 

Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 2.13 together with a written statement stating that such Security has never been issued and sold by the Company, for all purposes of
this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall not be entitled to the benefits of this Indenture. 
 Section 2.06. REGISTRAR AND PAYING AGENT; APPOINTMENT OF DEPOSITARY. 
 The
Company shall, in accordance with Section 4.02, maintain an office or agency where Securities may be presented for registration of transfer or for exchange (“Registrar”), (if Securities of any series are convertible) an office
or agency where Securities may be presented for conversion (“Conversion Agent”), and an office or agency where Securities may be presented for payment (“Paying Agent”). The Registrar shall keep a register of the
Securities and of their transfer and exchange. The Company may appoint one or more co-registrars, one or more additional paying agents and one or more Conversion Agents. The term “Registrar” includes any co-registrar, the term
“Paying Agent” includes any additional paying agent and the term “Conversion Agent” includes any additional Conversion Agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The
Company shall promptly notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent or, if the Securities of any series are
convertible, a Conversion Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent, Conversion Agent or Registrar. 
 The Company initially appoints The Depository Trust Company to act as Depositary with respect to the Global Securities. 
 The Company initially appoints the Trustee to act as the Registrar and Paying Agent with respect to the Securities and to act as Custodian with respect to the Global Securities. 

Section 2.07. PAYING AGENT TO HOLD MONEY IN TRUST. 
 The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held


  
 - 16 -









 
by the Paying Agent for the payment of principal, premium, if any, or interest on the Securities or other payment in respect of the Securities or otherwise held by it as Paying Agent, and will
notify the Trustee of any default by the Company in making any such payment when due. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying
Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it
shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the
Securities. 
 Section 2.08. HOLDER LISTS. 
 (a) The Company shall furnish or cause to be furnished to the Trustee, semiannually, and at such other times as the Trustee may request in writing, within 30 days after receipt by the Company of any such
request (or such lesser time as the Trustee may reasonably request in order to enable it to timely provide any notice to be provided by it hereunder), a list in such form as the Trustee may reasonably require of the names and addresses of the
Holders as of a date not more than 15 days (or such other date as the Trustee may reasonably request in order to so provide any such notices) prior to the time such information is furnished, except that no such list need be furnished so long as the
Trustee is acting as Registrar. In addition, the Trustee and the Company shall comply with TIA § 312. 
 (b) The
Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the Holders contained in the most recent list furnished to it as provided in this Section 2.08 or maintained by the
Trustee in its capacity as Registrar, if so acting. The Trustee shall destroy any list furnished to it as provided in this Section 2.08 upon receipt of a new list so furnished. 
 Section 2.09. TRANSFER AND EXCHANGE. 
 (a) Upon surrender for registration of
transfer of any Physical Security of any series at the office or agency maintained pursuant to Section 4.02, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one
or more new Physical Securities of the same series, of any authorized denominations and of a same aggregate principal amount and like tenor and containing identical terms and provisions. 

(b) At the option of the Holder, Securities of any series (except a Security in global form) may be exchanged for other Securities of the
same series, of any authorized denominations, of a same aggregate principal amount and like tenor and containing identical terms and provisions, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are
so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 

  
 - 17 -









 (c) Notwithstanding any other provision of this Section 2.09, unless and until it is
exchanged in whole or in part for Physical Securities, a Security in global form representing all or a portion of the Securities of a series may not be transferred except as a whole by the Depositary for such series to a nominee of such Depositary
or by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for such series or a nominee of such successor Depositary. 

(d) If at any time: (i) the Depositary for the Securities of a series notifies the Company that the Depositary is unwilling or
unable to continue as Depositary for the Securities of such series and a successor Depositary is not appointed within 60 days; (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor Depositary is
not appointed within 60 days; or (iii) an Event of Default with respect to the Securities of such series has occurred and is continuing and any beneficial owner requests that its Securities be issued as Physical Securities; then, in such cases,
the Company shall execute, and the Trustee, upon receipt of an Officers’ Certificate and an Authentication Order for the authentication and delivery of Physical Securities of such series of like tenor, shall authenticate and deliver (x) in
the case of clause (iii), a Physical Security of such series to such beneficial owner in a principal amount equal to the principal amount of such Securities corresponding to such beneficial owner’s beneficial interest and (y) in the case
of clause (i) or (ii), Physical Securities of such series to the beneficial owners of the related Securities (or a portion thereof) in an aggregate principal amount equal to the principal amount of such Global Security, in exchange for such
Global Security, and upon delivery of the Global Security to the Trustee such Global Security shall be cancelled. 
 (e) The
Company may at any time in its sole discretion determine that all (but not less than all) Securities of a series issued in global form shall no longer be represented by such a Security or Securities in global form. In such event the Company shall
execute, and the Trustee, upon receipt of an Authentication Order for the authentication and delivery of Physical Securities of such series of like tenor, shall authenticate and deliver in accordance with Section 2.02(g), Physical Securities of
such series of like tenor, in authorized denominations and in an aggregate principal amount equal to the principal amount of the Security or Securities of such series of like tenor in global form in exchange for such Security or Securities in global
form. 
 (f) If specified by the Company pursuant to Section 2.02 or this Section 2.09, with respect to a series of
Securities, the Depositary for such series may surrender a Security in global form of such series in exchange in whole or in part for Physical Securities of such series on such terms as are acceptable to the Company and such Depositary. Thereupon,
the Company shall execute, and the Trustee shall authenticate and deliver, without service charge, 
  

	 	(i)	to each Person specified by such Depositary a new Physical Security or Securities of the same series of like tenor, of any authorized denomination as requested by such
Person in aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the Security in global form; and 

  

	 	(ii)	to such Depositary a new Security in global form of like tenor in a denomination equal to the difference, if any, between the principal amount of the surrendered
Security in global form and the aggregate principal amount of Physical Securities delivered to Holders thereof. 


  
 - 18 -









 (g) Upon the exchange of a Security in global form for Physical Securities, such Security in
global form shall be canceled by the Trustee. Physical Securities issued in exchange for a Security in global form pursuant to this Section shall be registered in such names and in such authorized denominations as the Depositary for such Security in
global form, pursuant to instructions from its direct or Indirect Participants or otherwise, shall instruct the Trustee in writing. The Trustee shall deliver such Securities to the Persons in whose names such Securities are so registered.

 (h) Whenever any Securities are surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to receive. 
 (i) All Securities issued upon any
registration of transfer or upon any exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as were the Securities surrendered upon such registration of
transfer or exchange. 
 (j) Every Security presented or surrendered for registration of transfer or for exchange shall (if so
required by the Company, the Registrar or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company, the Registrar and the Trustee duly executed by the Holder thereof or his attorney
duly authorized in writing. 
 (k) No service charge shall be imposed by the Company, the Trustee or any Registrar for any
exchange or registration of transfer of Securities, but the Company, the Trustee or any Registrar may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required by law or permitted pursuant to
a supplemental indenture with respect to such Securities. None of the Company, the Trustee or any Registrar shall be required to exchange or register a transfer of any Securities surrendered for conversion or, if a portion of any Security is
surrendered for conversion, such portion thereof surrendered for conversion. 
 (l) The Company shall not be required
(i) to issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Securities of that series selected for
redemption under Section 3.02 and ending at the close of business on the day of such mailing, or (ii) to register the transfer of or exchange any security so selected for redemption in whole or in part, except the unredeemed portion of any
Security being redeemed in part. 
 (m) The provisions of this Section 2.09 may be modified, supplemented or superseded
with respect to any series of Securities by a Board Resolution or in one or more indentures supplemental hereto. 
 (n) At such
time as all beneficial interests in a particular Global Security have been exchanged for Physical Securities or a particular Global Security has been redeemed, 

  
 - 19 -









 
repurchased or canceled in whole and not in part, each such Global Security shall be returned to or retained and canceled by the Trustee in accordance with Section 2.13 hereof. At any time
prior to such cancellation, if any beneficial interest in a Global Security is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Security or for Physical Securities, the
principal amount of Securities represented by such Global Security shall be reduced accordingly and an endorsement shall be made on such Global Security by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction;
and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Security, such other Global Security shall be increased accordingly and an
endorsement shall be made on such Global Security by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. 
 (o) Prior to due presentment for the registration of a transfer of any Security, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Security is registered as the
absolute owner of such Security for the purpose of receiving payment of principal of and interest on such Securities and for all other purposes, and neither the Trustee, any Agent nor the Company shall be affected by notice to the contrary.

 Section 2.10. REPLACEMENT SECURITIES. 
 If any mutilated Security is surrendered to the Trustee or the Company or the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Security, the Company shall issue and
the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Security, provided that if required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of
the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Security is replaced. The Company may charge for its expenses in replacing a Security. 

Every replacement Security is an obligation of the Company and will be entitled to all of the benefits of this Indenture equally and
proportionately with all other Securities duly issued hereunder. 
 Section 2.11. OUTSTANDING SECURITIES. 

For purposes of this Indenture and the Securities, except as otherwise specified in any Security of any series or supplemental indenture
with respect to such Securities, any Security authenticated and delivered under this Indenture shall, as of any date of determination, be deemed to be “outstanding” except: 

(1) Securities theretofore cancelled by the Trustee or delivered to the Trustee for cancellation or reductions in the interest in any
Global Security effected by the Trustee in accordance with the provisions hereof; 
 (2) Securities for the payment or
redemption of which money or U.S. Government Obligations in the necessary amount has been theretofore deposited with the Trustee or any Paying Agent (other than the Company) in trust or set aside and segregated in trust by the


  
 - 20 -









 
Company (if the Company acts as its own Paying Agent) for the Holders of such Securities; provided, however, that, if such Securities are to be redeemed, notice of such redemption has been
duly given pursuant to this Indenture or provision therefore satisfactory to the Trustee has been made; 
 (3) Securities which
have been paid pursuant to Section 4.01; and 
 (4) Securities that have been replaced pursuant to Section 2.10, other
than any such Securities in respect of which there shall have been presented to the Trustee proof satisfactory to it that such Securities are held by a protected purchaser (as defined in Article 8 of the Uniform Commercial Code as in effect from
time to time in the State of New York) in whose hands such Securities are valid obligations of the Company; 
 provided, however, that in
determining whether the Holders of the requisite principal amount of the outstanding Securities have given or concurred with any request, demand, authorization, direction, notice, consent or waiver hereunder, Securities owned by the Company or any
other obligor upon the Securities or any Subsidiary of the Company or of such other obligor shall be disregarded and deemed not to be outstanding, except that, for purposes of determining whether the Trustee shall be protected in relying upon any
such request, demand, authorization, direction, notice, consent or waiver, only Securities which the Trustee knows to be so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be regarded as outstanding if
the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not the Company or any other obligor upon the Securities or any Affiliate of the Company or of such
other obligor. 
 Section 2.12. TEMPORARY SECURITIES. 
 Until certificates representing Securities are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Securities. Temporary
Securities shall be substantially in the form of Physical Securities but may have variations that the Company considers appropriate for temporary Securities and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the
Company shall prepare and the Trustee shall authenticate definitive Securities in exchange for temporary Securities. 
 Holders
of temporary Securities will be entitled to all of the benefits of this Indenture. 
 Section 2.13. PURCHASE AND CANCELLATION. 

The Company shall cause all Securities surrendered for payment, repurchase, registration of transfer or exchange or conversion, if
surrendered to any Person other than the Trustee (including any of the Company’s Agents, Subsidiaries or Affiliates), to be delivered to the Trustee for cancellation. All Securities delivered to the Trustee shall be canceled promptly by the
Trustee. No Securities shall be authenticated in exchange for any Securities cancelled, as provided herein. The Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Securities are surrendered to the
Company), repurchase Securities in the open market or otherwise, without giving prior notice to Holders, whether by the Company or the Company’s Subsidiaries or through a private or public tender or exchange offer or through


  
 - 21 -









 
counterparties to private agreements, including by cash-settled swaps or other derivatives. The Company may cause any Securities so repurchased (other than Securities repurchased pursuant to
cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with this Section 2.13 and any such Securities shall no longer be considered outstanding under this Indenture upon such repurchase. Any
Securities surrendered for cancellation by the Company shall not be reissued or resold. 
 Section 2.14. DEFAULTED INTEREST. 

If the Company defaults in a payment of interest on the Securities, it shall pay the defaulted interest in any lawful manner to the
Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Securities. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Security and the date
of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date, provided, however, that no such special record date shall be less than 10 days prior to the related payment date for such
defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that
states the special record date, the related payment date and the amount of such interest to be paid. Except as otherwise expressly provided in Section 2.03 or a supplemental indenture with respect to such Securities, in the case of any Security
(or any part thereof) which is converted, interest payable on an Interest Payment Date after the date of conversion of such Security (or such part thereof) shall not be payable. 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 2.15. BOOK-ENTRY PROVISIONS FOR GLOBAL SECURITIES. 
 (a) Except as otherwise specified in any Security of any series or supplemental indenture with respect to such Securities, the Securities of each series issued hereunder shall initially be issued in the
form of one or more Global Securities without interest coupons (i) registered in the name of Cede & Co., as nominee of the Depositary and (ii) delivered to the Trustees as custodian for the Depositary. 

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 Cede & Co., or such other Person designated by the Depositary as its nominee, may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Security for all purposes whatsoever. 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 any Holder. 

  
 - 22 -









 (b) The Holder of Global Securities may grant proxies and otherwise authorize any Person,
including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this Indenture or the Securities. 
 (c) A legend in substantially the following form shall appear on the face of all Global Securities: 
 THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE OF A DEPOSITARY. THIS SECURITY IS EXCHANGEABLE FOR
SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND NO TRANSFER OF THIS SECURITY (OTHER THAN A TRANSFER OF THIS SECURITY AS A WHOLE BY THE
DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY) MAY BE REGISTERED EXCEPT IN LIMITED CIRCUMSTANCES. 

UNLESS THIS SECURITY IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION
(“DTC”), TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY SECURITY ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC
(AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE
REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

appropriate; provided, however, that no Securities of $1,000 or less shall be redeemed in part. In the event of partial redemption by lot, the particular Securities of such series to be redeemed shall be selected, unless otherwise provided
herein or in the Securities of such series or in a supplemental indenture with respect to such Securities or otherwise agreed by the Company and the Trustee, by the Trustee from the outstanding Securities of the series not previously called for
redemption. 
 The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the
case of any Security selected for partial redemption, the principal amount thereof to be redeemed. Securities and portions of Securities selected shall be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Securities of a
series of a Holder are to be redeemed, the entire outstanding amount of Securities of such series held by such Holder, even if not a multiple of $1,000, shall be redeemed. A new Security of the same series in principal amount equal to the unredeemed
portion thereof shall be issued in the name of the Holder thereof upon cancellation of the original Security. Securities called for redemption shall become due on the redemption date. On and after the redemption date, interest will cease to accrue
on the Securities or portions of them called for redemption. Except as provided in this Section 3.02, provisions of this Indenture that apply to Securities called for redemption shall also apply to portions of Securities called for redemption.

 (6) as to any Security 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 of the same series in principal amount equal to the unredeemed portion shall be issued upon cancellation of the
original;

 (7) the paragraph of the Securities and/or Section of this Indenture, any supplemental
indenture with respect to such Securities or any Securities pursuant to which the Securities called for redemption are being redeemed; and 
 (8) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Securities.

expense; provided, however, that the Company shall have delivered to the Trustee, at least 45 days prior to the redemption date (unless a shorter period is 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.

Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Securities to be redeemed. 

Section 3.06. SECURITIES REDEEMED OR PURCHASED IN PART. 
 Upon surrender of a Security that is redeemed in part, the Company shall issue and, upon the Company’s written request, the Trustee shall authenticate for the Holder at the expense of the Company a
new Security of the same series equal in principal amount to the unredeemed portion of the Security surrendered. 
 Section 3.07. MANDATORY
REDEMPTION; SINKING FUND. The Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Securities, unless otherwise specified in the terms of a particular series of Securities or in a supplemental
indenture with respect to such Securities.

in the location, of any such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Trustee’s principal agency, which currently is located at:

such portions of any of the foregoing as the SEC may from time to time by rules and regulations prescribe) that the Company is required to file with the SEC pursuant to Section 13 or 15(d)
of the Exchange Act. 
 Delivery of such reports, information and documents to the Trustee is for informational purposes only
and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as
to which the Trustee is entitled to rely exclusively on Officers’ Certificates). Any such document or report that the Company files with the SEC via the EDGAR system shall be deemed to be filed with the Trustee for purposes of this
Section 4.03 as of the time such documents are filed via the EDGAR system. 
 Section 4.04. COMPLIANCE CERTIFICATE. 

The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof,

thereof is no longer desirable in the conduct of the business of the Company, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Securities. 

ARTICLE 5. 

SUCCESSOR COMPANY 

Section 5.01. CONSOLIDATION, MERGER AND SALE OF ASSETS. 
 The Company shall not consolidate with or merge with or into, or sell, transfer, lease or otherwise convey all or substantially all of its consolidated assets to, another Person, unless: 

(a) the resulting, surviving or transferee Person (if not the Company) (the “Successor Company”) is a corporation
organized and existing under the laws of the United States, any State thereof or the District of Columbia and such Successor Company (if not the Company) expressly assumes by supplemental indenture all of the Company’s obligations under the
Securities and this Indenture; 

  
 - 27 -









 (b) immediately after giving effect to such transaction (and treating such resulting,
surviving or transferee Person as the Company for all such purposes hereunder), no Default or Event of Default shall occur and be continuing under this Indenture; and 
 (c) the Company delivers to the Trustee the Officers’ Certificate and Opinion of Counsel pursuant to Section 5.03. 
 For purposes of this Section 5.01, the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of one or more Subsidiaries of the Company to another Person that
is not a Subsidiary of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to
be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person. 

Section 5.02. SUCCESSOR PERSON SUBSTITUTED. 
 In the case of any consolidation, merger, sale, transfer, lease or other conveyance pursuant to Section 5.01 in which the Company is not the Successor Company, and upon the assumption by the
Successor Company, by supplemental indenture, executed and delivered to the Trustee, of the due and punctual payment of the principal of and interest on all of the then outstanding Securities, and the due and punctual performance and observance of
all of the covenants and conditions of this Indenture to be performed or satisfied by the Company, such Successor Company shall succeed to, and be substituted for, and may exercise every right and power of, the Company, with the same effect as if it
had been named herein as the party of the first part, and the Company shall be discharged from its obligations under the terms of the Securities and this Indenture, except in the case of a lease of all or substantially all of the Company’s
properties and assets. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Securities issuable hereunder that theretofore shall not have been signed by the
Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or
cause to be authenticated and delivered, any Securities that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Securities that such Successor Company thereafter shall cause to
be signed and delivered to the Trustee for that purpose. All the Securities so issued shall in all respects rank equally and have the same benefit under this Indenture as the Securities theretofore or thereafter issued in accordance with the terms
of this Indenture as though all of such Securities had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, transfer or conveyance (but not in the case of a lease) upon compliance with this Article 5
the Person named as the “Company” in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 5 shall be discharged from its liabilities as obligor and maker of
the Securities and from its obligations under this Indenture. 

  
 - 28 -









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

Section 5.03. OPINION OF COUNSEL TO BE GIVEN TO TRUSTEE. 
 Prior to execution of any supplemental indenture pursuant to this Article 5, the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel in accordance with Section 13.05 as
conclusive evidence that any such consolidation, merger, sale, transfer, or other conveyance or lease, and any such assumption by the Successor Company of the obligations of the Company hereunder, complies with the provisions of this Article 5.

 ARTICLE 6. 
 EVENTS OF DEFAULT 
 Section 6.01. EVENTS OF DEFAULT. 

Except as may otherwise be provided in the Securities of any series or a supplemental indenture with respect to such Securities, an
“Event of Default,” with respect to Securities of any series shall have occurred if: 
 (a) the Company
defaults in the payment of principal of any Security of that series when due and payable on the Maturity Date with respect thereto; 
 (b) the Company fails to pay an installment of interest on any Security of that series when due, if such failure continues for 30 days after the date when due; 

(c) upon exercise of a Holder’s conversion right with respect to any Security of that series in accordance with Article 12, the
Company fails to deliver, or cause the Trustee to deliver, to such Holder the full amount of conversion consideration deliverable in respect of the Securities surrendered for conversion when due, in accordance with this Indenture and the terms of
such Securities; 
 (d) the Company fails to comply with its obligations under Section 5.01(a) and (b) and
Section 5.02; 
 (e) the Company fails to comply with any other covenant or agreement contained in the terms of the
Securities of that series or this Indenture, if such failure is not cured within 90 days after notice to the Company by the Trustee or to the Trustee and the Company by Holders of at least 25% in aggregate principal amount of the then outstanding
Securities of all series affected by that failure, treating those series as a single class, in accordance with this Indenture, other than a covenant or agreement with respect to which a failure to observe or perform is otherwise expressly provided
for in this Indenture or is expressly included in this Indenture solely for the benefit of a series of the Securities other than such series of Securities; 
 (f) default (i) in any scheduled payment of principal of any Indebtedness of the Company or any of its Subsidiaries (other than the outstanding Securities of that series and other

any other term or provision of any Indebtedness of the Company or any of its Subsidiaries (other than the outstanding Securities of that series and other than non-recourse Indebtedness) in excess of $100,000,000 principal amount that results in such
Indebtedness becoming or being declared due and payable before the date on which it would otherwise become due and payable, and such acceleration is not rescinded or annulled, or such Indebtedness is not discharged, within a period of 20 days after
there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the outstanding Securities of all series, treating those series as a single
class, a written notice specifying such default(s) and stating that such notice is a “Notice of Default” under this Indenture;

appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 90 consecutive days. 

Section 6.02. ACCELERATION; RESCISSION AND ANNULMENT. 
 In case one or more Events of Default shall have occurred and be continuing with respect to one or more series of Securities then, and in each and every such case (other than an Event of Default specified
in Section 6.01(h) or Section 6.01(i)), unless the principal of all of the Securities of all series with respect to which an Event or Events of Default shall have occurred, shall have already become due and payable, either the Trustee or
the Holders of at least 25% in aggregate principal amount of the then outstanding Securities of all series affected by that failure, treating those series as a single class, by notice in writing to the Company (and to the Trustee if given by
Holders), may, and the Trustee at the request of Holders of at least 25% in aggregate principal amount of the then outstanding Securities of all series affected by that failure, treating those series as a single class, shall, declare 100% of the
principal of, and any accrued and unpaid interest on, all of such outstanding Securities to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be


  
 - 30 -









 
due and payable immediately, notwithstanding any provision in this Indenture or in the terms of the Securities to the contrary. In the case of an Event of Default specified in
Section 6.01(h) or Section 6.01(i), the principal of, and accrued and unpaid interest, if any, on, all outstanding Securities shall automatically become due and payable immediately. 

The immediately preceding paragraph, however, is subject to the conditions that if, at any time after the principal of and interest on
the outstanding Securities of any series shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, (1) the Company shall pay or
shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all outstanding Securities of such series and the principal of any and all outstanding Securities of such series that shall have become due
otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal, at the rate borne by the outstanding
Securities plus one percent at such time) and amounts due to the Trustee pursuant to Section 7.06, and (2) rescission would not conflict with any order or decree of a court of competent jurisdiction and (3) any and all existing Events
of Default under this Indenture with respect to the Securities of such series, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on such Securities that shall have become due solely by such acceleration, shall
have been cured or waived pursuant to Section 6.09, then and in every such case the Holders of a majority in aggregate principal amount of the then outstanding Securities of all series affected by that failure, treating those series as a single
class may, by written notice to the Company and to the Trustee, rescind and annul any consequence of any such Default or Event of Default, including, without limitation, acceleration of the obligations, and any Event of Default arising therefrom
shall be deemed to have been cured for every purpose of this Indenture; but no such rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. 

Section 6.03. ADDITIONAL INTEREST. 
 Notwithstanding any provisions of this Indenture to the contrary, if the Company so elects, the sole remedy for an Event of Default relating to (i) its failure to file with the Trustee pursuant to
Section 314(a)(1) of the Trust Indenture Act any documents or reports that it is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act or (ii) its failure to comply with its reporting obligations set forth
in Section 4.03, shall for the 180 days after the occurrence of such an Event of Default consist exclusively of the right to receive additional interest on the Securities at a rate equal to 0.25% per annum of the principal amount of the
outstanding Securities (“Additional Interest”) for each day during the 90-day period beginning on, and including, the occurrence of such an Event of Default during which such Event of Default is continuing, which Additional Interest
rate shall be increased by an additional 0.25% per annum, on the 91st day after the occurrence of such Event of Default (if such Event of Default is not cured or waived prior to such 91st day); provided that the rate at which such
Additional Interest accrues may in no event exceed 0.50% per annum. If the Company elects to pay Additional Interest on account of such an Event of Default, such Additional Interest shall be payable in the same manner and on the same dates as
the stated interest payable on the Securities. On the 181st day after such Event of Default occurs (if such Event of Default is not cured or waived on or prior to such 181st day), the Securities shall be subject to acceleration as


  
 - 31 -









 
provided in Section 6.02. This Section 6.03 shall not affect the rights of Holders of Securities in the event of the occurrence of any other Event of Default. In the event the Company
does not elect to pay Additional Interest following an Event of Default in accordance with this Section 6.03, the Securities shall be subject to acceleration as provided in Section 6.02. 

In order to elect to pay Additional Interest as the sole remedy during the first 180 days after the occurrence of an Event of Default
described in the immediately preceding paragraph, the Company must give notice to Holders of the Securities, the Trustee and the Paying Agent of such election prior to the 91st day after the occurrence of such Event of Default. Upon the
Company’s failure to timely give all Holders, the Trustee and the Paying Agent such notice, the Securities shall be immediately subject to acceleration as provided in Section 6.02. 
 Section 6.04. PAYMENTS OF SECURITIES ON DEFAULT; SUIT THEREFOR. 
 If an Event
of Default described in clause (a) or (b) of Section 6.01 shall have occurred with respect to the Securities of any series, the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities,
the whole amount then due and payable on the Securities of such series for principal and interest, if any, with interest on any overdue principal and interest, if any, at the rate borne by such Securities plus one percent at such time, and, in
addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an
express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Securities of
such series and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated. 

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the
Securities under title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken
possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Securities, or to the creditors or property
of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any
demand pursuant to the provisions of this Section 6.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if
any, in respect of the Securities, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem 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 of the Holders of the Securities of any series allowed in such judicial proceedings relative to the Company or any
other obligor on the Securities, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to 

  
 - 32 -









 
distribute the same after the deduction of any amounts due the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or
similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including reasonable agents and counsel fees, and including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of
such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and
shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or
otherwise. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities of any series or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding. 
 All rights of action and of asserting claims under this Indenture, or under any of the Securities, may be
enforced by the Trustee without the possession of any of the Securities, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders.

 In any proceedings brought by the Trustee with respect to the Securities of any series (and in any proceedings involving the
interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Securities affected thereby, and it shall not be necessary to make any Holders parties to any such
proceedings. 
 In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall
have been discontinued or abandoned because of any waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders, and the Trustee shall,
subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders, and the Trustee shall continue as though no such proceeding
had been instituted. 
 Section 6.05. APPLICATION OF MONIES COLLECTED BY TRUSTEE. 

If the Trustee collects any money or other property pursuant to this Article, it shall pay out the money or other property in the
following order: 
 First: to the Trustee, its agents and attorneys for amounts due under Section 7.06 hereof,
including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

  
 - 33 -









 Second: to Holders of Securities for amounts due and unpaid on the Securities for
principal, premium, if any, interest and any other amounts, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal, premium, if any, interest and other amounts, respectively; and

 Third: to the Company or to such party as a court of competent jurisdiction shall direct. 

The Trustee may fix a record date and payment date for any payment to Holders of Securities pursuant to this Section 6.05.

 Section 6.06. PROCEEDINGS BY HOLDERS. 
 Except to enforce the right to receive payment of principal or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, the Holder of a Security shall have
the right to institute a suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy
hereunder, if (and only if): 
 (a) such Holder previously shall have given to the Trustee written notice of an Event of Default
with respect to such Securities and of the continuance thereof, as herein provided; 
 (b) Holders of at least 25% in aggregate
principal amount of the then outstanding Securities of all series with respect to which such Event of Default has occurred and is continuing, treating those series as a single class, shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as Trustee hereunder; 
 (c) such Holder or Holders shall have offered, and, if
requested, provided, to the Trustee such indemnity reasonably satisfactory to it against any loss, liability or expense to be incurred therein or thereby; and 
 (d) the Trustee shall have neglected or refused to institute any such action, suit or proceeding for 60 days after its receipt of such notice, request and offer of indemnity and does not receive, during
those 60 days, from Holders of a majority in aggregate principal amount of the then outstanding Securities of all series with respect to which such Event of Default has occurred and is continuing, treating those series as a single class, a direction
pursuant to Section 6.09 that is inconsistent with the request, it being understood and intended, and being expressly covenanted by the taker and Holder of every Security with every other taker and Holder and the Trustee that no one or more
Holders of Securities of any series shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder, 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 such Securities (except as otherwise provided herein).
For the protection and enforcement of this Section 6.06, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 

  
 - 34 -









 Notwithstanding any other provision of this Indenture and any provision of any Security, the
right of any Holder to receive payment or delivery, as the case may be, of (x) the principal of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion, if any, of, such Security, on or after the
respective due dates expressed or provided for in such Security or in this Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective dates against the Company shall not be
impaired or affected without the consent of such Holder. 
 Section 6.07. PROCEEDINGS BY TRUSTEE. 

In case of an Event of Default the Trustee may, in its discretion, proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any
covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 

Section 6.08. REMEDIES CUMULATIVE AND CONTINUING. 
 All powers and remedies given by this Article 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and
remedies available to the Trustee or the Holders, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder of
any Securities to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject
to the provisions of Section 6.06, every power and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders.

 Section 6.09. DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY MAJORITY HOLDERS. 

The Holders of a majority in aggregate principal amount of the then outstanding Securities of all series with respect to which a Default
or Event of Default has occurred, treating those series as a single class, shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on
the Trustee with respect to the Securities of such series; provided, however, that the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines is unduly prejudicial to the rights of
any other Holder or that would involve the Trustee in personal liability. The Holders of a majority of the aggregate principal amount of the then outstanding Securities of all series with respect to which a Default or Event of Default has occurred,
treating those series as a single class, may on behalf of the Holders of all 

  
 - 35 -









 
of the Securities of such series, treating those series as a single class, by written notice to the Trustee and the Company, waive any Default or Event of Default with respect to such Securities
hereunder except that no such waiver shall be effective as to a Default or Event of Default (i) in the payment of the principal of, or accrued and unpaid interest, if any, on the Securities, (ii) arising from a failure by the Company to
pay or deliver, as the case may be, or to cause the Trustee to deliver, to converting Holders the consideration, if any, due upon conversion of the Securities in accordance with this Indenture or (iii) in respect of a covenant or provision
hereof that under Article 10 cannot be modified or amended without the consent of the Holder of each outstanding Security affected unless each affected Holder consents. Upon any such waiver the Company, the Trustee and the Holders of the Securities
of such series shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default
hereunder shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the Securities of such series and this Indenture be deemed to have been cured and to be not continuing; but no such
waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 
 Section 6.10. NOTICE
OF DEFAULTS. 
 The Trustee shall, within 90 days after the occurrence of a Default of which a Responsible Officer has actual
knowledge, if such Default is continuing, mail to all Holders of Securities of each series with respect to which the Default has occurred, as the names and addresses of such Holders appear upon the Security Register, notice of all such Defaults
known to a Responsible Officer (a “Notice of Default” or “Notice of Defaults”), unless such Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a
Default in the payment of the principal of, or accrued and unpaid interest on, any of the Securities or a Default in the payment or delivery, as the case may be, of the consideration, if any, due upon conversion, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests
of the Holders. 
 Section 6.11. STATEMENTS AS TO DEFAULTS. 
 The Company shall deliver to the Trustee, as soon as possible, and in any event within 30 days after the occurrence of any Event of Default or Default, an Officers’ Certificate setting forth the
details of such Event of Default or Default, its status and the action that the Company is taking or proposes to take in respect thereof. 

Section 6.12. FURTHER INSTRUMENTS AND ACTS. 
 Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of
this Indenture. 

  
 - 36 -









 Section 6.13. UNDERTAKING TO PAY COSTS. 

All parties to this Indenture agree, and each Holder of any Security by its acceptance thereof shall be deemed to have agreed, that any
court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture or the Securities, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due
regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.13 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any
suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the then outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement of the payment of the
principal of or accrued and unpaid interest, if any, on any Security on or after the due date expressed or provided for in such Security or to any suit for the enforcement of the right to convert any Security in accordance with the provisions of
Article 12. 
 ARTICLE 7. 
 TRUSTEE 
 Section 7.01. DUTIES OF TRUSTEE. 

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this
Indenture or an indenture supplemental hereto applicable to such Event of Default, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of its own affairs.

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

(i) the duties of the Trustee shall be determined solely by the express provisions of this Indenture or an indenture supplemental hereto,
and the Trustee need perform only those duties that are specifically set forth in this Indenture or an indenture supplemental hereto and no others, and no implied covenants or obligations shall be read into this Indenture or an indenture
supplemental hereto against the Trustee; and 
 (ii) in the absence of bad faith on its part, the Trustee may conclusively rely,
as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine the certificates
and opinions to determine whether or not they conform to the requirements of this Indenture. 
 (c) The Trustee may not be
relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 
 (i) this paragraph does not limit the effect of paragraph (b) of this Section 7.01; 

  
 - 37 -









 (ii) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer, unless it is proven that the Trustee was negligent in ascertaining the pertinent facts; and 
 (iii) the
Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.09 hereof. 

(d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b), and (c) of this Section 7.01. 
 (e) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

 (a) The Trustee may conclusively rely upon
any document 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. 

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The
Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel, and the written advice of such counsel or any Opinion of
Counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. 

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

 (e) Unless otherwise
specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company. 
 (f) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee shall be under no obligation to exercise any of the rights or powers vested
in it by this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee reasonable security or indemnity satisfactory to it against the costs, expenses and liabilities that might be incurred by it in
compliance with such request or direction. 

  
 - 38 -









 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 Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (within the meaning of TIA § 310(b)) it must eliminate such conflicting interest
within 90 days after Default, apply to the SEC for permission to continue as trustee, or resign. Any Agent may do the same with like rights and duties. 
 Section 7.04. TRUSTEE’S DISCLAIMER. 
 The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of this Indenture or the Securities; it shall not be accountable for the Company’s use of the proceeds from the Securities or any money paid to the Company or upon the
Company’s direction under 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 or recital
herein or any statement in the Securities or any other document in connection with the sale of the Securities or pursuant to this Indenture other than its certificate of authentication. 
 Section 7.05. REPORTS BY TRUSTEE TO HOLDERS OF THE SECURITIES. 
 On or before
March 1 of each year, beginning with the March 1 following the date on which Securities are first issued under this Indenture, and for so long as Securities remain outstanding, the Trustee shall mail to the Holders of the Securities a
brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also
shall comply with TIA § 313(b)(2). The Trustee will also transmit by mail all reports as required by TIA § 313(c). A copy of each report at the time of its mailing to the Holders of Securities shall be mailed to the Company and filed with
the SEC and each stock exchange on which the Securities are listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee when the Securities are listed on any stock exchange. 

Section 7.06. COMPENSATION AND INDEMNITY. 
 The Company shall pay to the Trustee from time to time such compensation for its acceptance of this Indenture and services hereunder as the Company and Trustee have separately agreed. The Trustee’s
compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition
to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 
 The Company shall indemnify the Trustee against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this
Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 7.06) and defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in
connection with the exercise or performance of any of its powers or duties hereunder, except to the extent 

  
 - 39 -









 
any such loss, liability or expense may be attributable to its negligence or willful misconduct. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity.
Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim, and the Trustee shall cooperate in the defense. The Trustee may have separate counsel, and the Company
shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. 

The obligations of the Company under this Section 7.06 shall survive the satisfaction and discharge of this Indenture, and the
removal or resignation of the Trustee. 
 To secure the Company’s payment obligations in this Section 7.06, the
Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal of, premium, if any, and interest on particular Securities. Such lien shall survive the
satisfaction and discharge of this Indenture. 
 When the Trustee incurs expenses or renders services after an Event of Default
specified in Section 6.01(h) or (i) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy
Law. 
 Section 7.07. REPLACEMENT OF TRUSTEE. 
 A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this
Section 7.07. 
 The Trustee may resign with respect to one or more or all series of Securities at any time and be
discharged from the trust hereby created by so notifying the Company in writing. The Holders of a majority in principal amount of the then outstanding Securities of any series may remove the Trustee with respect to such series by so notifying the
Trustee and the Company in writing. The Company may remove the Trustee if: 
 (a) the Trustee ceases to be eligible in
accordance with Section 7.09 hereof; 
 (b) the Trustee is adjudged bankrupt or insolvent or an order for relief is entered
with respect to the Trustee under any Bankruptcy Law; 
 (c) a custodian or public officer takes charge of the Trustee or its
property; or 
 (d) the Trustee becomes incapable of acting. 

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Securities of a series may appoint a successor Trustee to replace the successor Trustee appointed by
the Company with respect to that series of Securities. 

  
 - 40 -









 If a successor Trustee does not take office within 60 days after the retiring Trustee
resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in principal amount of the then outstanding Securities of all series issued under this Indenture may petition any court of competent jurisdiction for the
appointment of a successor Trustee. 
 If the Trustee, after written request by any Holder of a Security who has been a Holder
of a Security for at least six months, ceases to be eligible in accordance with Section 7.09, such Holder of a Security may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company.
Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders of the Securities. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee subject to the lien provided for in Section 7.06 hereof. Notwithstanding replacement of the
Trustee pursuant to this Section 7.07, the Company’s obligations under Section 7.06 hereof shall continue for the benefit of the retiring Trustee. 
 If a successor Trustee is appointed 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 any
applicable series shall execute and deliver an indenture supplemental hereto which 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 any series as to which the predecessor Trustee is not retiring shall continue to be vested in the predecessor Trustee, and shall add to or change any of the provisions of this Indenture as are 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 as co-trustees of the same trust and 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. 

Section 7.08. SUCCESSOR TRUSTEE BY MERGER, ETC. 
 If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall
be the successor Trustee. 
 Section 7.09. ELIGIBILITY; DISQUALIFICATION. 

There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of
America or of any state thereof that is authorized under such laws to exercise corporate trust powers, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $500,000,000
as set forth in its most recent published annual report of condition. 
 This Indenture shall always have a Trustee who
satisfies the requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b); provided, however, that there 

  
 - 41 -









 
shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities, or certificates of interest or participation in other securities, of the
Company are outstanding, if the requirements for such exclusion set forth in TIA § 310(b)(1) are met. 
 Section 7.10. PREFERENTIAL
COLLECTION OF CLAIMS AGAINST COMPANY. 
 The Trustee is subject to TIA § 311(a), excluding any creditor relationship
described in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. 
 ARTICLE 8. 
 SATISFACTION AND DISCHARGE 

Section 8.01. SATISFACTION AND DISCHARGE OF THE INDENTURE. 
 (a) The obligations of the Company under this Indenture shall terminate with respect to the Securities of one or more series (except those obligations referred to in Section 8.01(b)), (1) if
(i) all Securities of such series theretofore authenticated and delivered (except Securities that have been replaced pursuant to Section 2.10 or paid and Securities whose payment in cash has theretofore been deposited with the Trustee or a
Paying Agent or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust as provided in Section 8.04) have been delivered to the Trustee for cancellation; and (ii) the Company has paid

Company, pursuant to Article 3, has given notice to the Trustee and mailed a notice of redemption to each Holder of Securities of such series of the redemption of all of such Securities under arrangements satisfactory to the Trustee for the giving
of such notice or (B) all Securities of such series have otherwise become due and payable hereunder or will become due and payable within one year; (ii) the Company has irrevocably deposited or caused to be deposited with the Trustee or
the Paying Agent (or if the Company is acting as Paying Agent, the Company has segregated and held), as trust funds in trust solely for the benefit of the Holders of Securities of such series for that purpose, either (A) an amount of cash in
United States dollars, (B) non-callable U.S. Government Obligations which, through scheduled payment of principal and interest in respect thereof in accordance with their terms, will provide, not later than one Business Day before the due date
of any payment of principal of, premium, if any, or interest on the Securities of such series, cash in an amount, or (C) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay
the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for the principal of, premium, if any, and interest on the outstanding Securities of such series to the date of such deposit (in the case of
Securities which have become due and payable) or to the stated maturity or redemption date, as the case may be; and (iii) the Company shall have paid all other sums payable by it hereunder in respect of Securities of such series (including any

Sections 2.08, 2.09, 2.10, 2.11, 4.01 and 4.02 shall survive with respect to the Securities of the applicable series 

  
 - 42 -









 
until the sums held in trust pursuant to Section 8.01(a) are made available to the Holders of the Securities of such series on the Stated Maturity Date. Sections 7.06, 8.04 and 9.06 shall
survive such discharge of the Company’s other obligations pursuant to the preceding sentence in respect of Securities of the applicable series. 
 (c) This Indenture shall upon request of the Company contained in an Officers’ Certificate cease to be of further effect with respect to the Securities of any series, and the Trustee, at the expense
of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) (i) all Securities of such series theretofore authenticated and delivered have been delivered to the Trustee for
cancellation; or (ii) the Company has deposited with the Trustee or delivered to Holders, as applicable, after the Securities of such series have become due and payable, whether at the Maturity Date, upon conversion or otherwise, cash and/or

Company with respect to such Securities; and (b) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and
discharge of this Indenture with respect to such Securities have been complied with. For the avoidance of doubt, notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.06
shall survive. The Trustee upon request shall acknowledge in writing the discharge of the Company’s obligations under the Securities of the applicable series and the Company’s obligations under this Indenture with respect to the Securities
of such series, except for those surviving obligations specified above. 
 Section 8.02. DEPOSITED MONEYS TO BE HELD IN TRUST BY TRUSTEE.

released from all further liability with respect to such monies and other property.

Subject to the requirements of applicable law, any monies and other property deposited with or paid to the Trustee for payment on the
Securities of a particular series and not applied but remaining unclaimed by the Holders of the Securities for one year after the date upon which the payment on such Securities shall have become due and payable, shall be repaid to the Company by the
Trustee on demand, and all liability of the Trustee shall thereupon cease with respect to such monies and other property; and the Holder of any of the Securities shall thereafter look only to the Company for any payment or delivery that such Holder
of the Securities may be entitled to collect unless an applicable abandoned property law designates another Person. 
 Section 8.05.
REINSTATEMENT. 
 If the Trustee or the Paying Agent is unable to apply any money or other property in accordance with
Section 8.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Securities shall be revived and
reinstated as though no deposit had occurred pursuant to Section 8.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money and other property in accordance with Section 8.02; provided, however, that if
the Company makes any payment of interest on, principal of or payment or delivery in respect of any Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive
such payment from the money or other property, if any, held by the Trustee or Paying Agent.

 The
Company may, by written direction to the Trustee, at any time, elect to have either Section 9.02 or 9.03 hereof, with such modifications thereto as may be specified in the supplemental indenture establishing a particular series of Securities,
be applied to all outstanding Securities of one or more series upon compliance with the conditions set forth below in this Article 9. 

Section 9.02. LEGAL DEFEASANCE AND DISCHARGE.

the conditions set forth in Section 9.04 hereof, be deemed to have been discharged from its obligations with respect to all outstanding Securities of such series on the date the conditions set forth below are satisfied (hereinafter,
“Legal Defeasance”). For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the outstanding Securities of the applicable series, except as set
forth in Section 9.05 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all of its other obligations under the Securities of the applicable series and under the provisions of this
Indenture applicable to such series (and the Trustee, on demand of and at the 

  
 - 44 -









 
expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:
(a) the rights of Holders of outstanding Securities of the applicable series to receive solely from the trust fund described in Section 9.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of,
premium, if any, and interest, on such Securities when such payments are due, (b) the Company’s obligations with respect to such Securities under Section 4.02 hereof, (c) the rights, powers, trusts, duties and immunities of the

 Section 9.03. COVENANT DEFEASANCE. 
 Upon the Company’s exercise under
Section 9.01 hereof of the option applicable to this Section 9.03 relating to one or more series of Securities, the Company shall, upon the satisfaction of the conditions set forth in Section 9.04 hereof, be released from its

Securities or other terms of the applicable series as covenants to which this Section 9.03 apply, on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Securities of
the applicable series shall thereafter not be deemed outstanding for the purposes of any direction, waiver, consent or declaration or act of Holders (or 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, Covenant Defeasance means that, with respect to the outstanding Securities of the applicable 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 hereof, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby.

 Section 9.04. CONDITIONS TO LEGAL OR COVENANT DEFEASANCE. 
 The following shall be the conditions to the application of either Section 9.02 or 9.03 hereof to the outstanding Securities of one or more series:

based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Securities of the applicable series will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be

(e) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

on or assessed against the cash or non-callable U.S. Government Obligations deposited pursuant to Section 9.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of the outstanding Securities of the applicable series. 
 Anything in this Article 9 to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or non-callable U.S. Government Obligations held by it as provided in Section 9.04 hereof which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 9.04(a) hereof), are in excess of the amount thereof that would
then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance of the applicable series. 
 Section 9.06.
REINSTATEMENT. 
 If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable U.S. Government
Obligations deposited pursuant to Section 9.02 or 9.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, or if any amounts
previously applied are required to be returned to the Company or to any trustee in connection with any proceeding referred to in Section 6.01(h) or (i) then the obligations of the Company under this Indenture and the Securities shall be
revived and reinstated as though no deposit had occurred pursuant to Section 9.02 or 9.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 9.02 or 9.03 hereof, as the
case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders
of such Securities to receive such payment from the money held by the Trustee or Paying Agent.

described in Section 7.02(b) hereof, the Trustee shall join with the Company in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and

case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental indenture. 
 Section 10.02.

Section 10.03. NOTICE OF AMENDMENT OR SUPPLEMENT.

a quorum within 30 minutes after the time appointed for any such meeting, the meeting shall, if convened at the request of Holders of Securities of such series, be dissolved. In any other case the meeting may be adjourned for a period determined by
the chairman of the meeting prior to the adjournment of such meeting. In the absence of a quorum at any reconvened meeting, such reconvened meeting may be further adjourned as determined by the chairman of the meeting prior to the adjournment of
such adjourned meeting. Notice of the reconvening of any such adjourned meeting shall be given as provided in Section 11.02(a), except that such notice need be given only once not less than five days prior to the date on which the meeting is
scheduled to be reconvened. Notice of the reconvening of an adjourned meeting shall state expressly the percentage, as provided above, of the principal amount of the outstanding Securities of such series which shall constitute a quorum. 

Except as otherwise provided in Section 6.02 or 10.02 (or in any indenture supplemental hereto establishing a series of Securities
hereunder), any resolution presented to a meeting or adjourned meeting duly reconvened at which a quorum is present as aforesaid may be adopted only by the affirmative vote of the Holders of a majority in principal amount of the outstanding
Securities of that series; provided, however, that, except as otherwise provided in Section 6.02 or 10.02 (or in any indenture supplemental hereto establishing a series of Securities hereunder), any resolution with respect to any
request, demand, authorization, direction, notice, consent, waiver or other action which this Indenture or any supplemental indenture expressly provides may be 

  
 - 51 -









 
made, given or taken by the Holders of a specified percentage in principal amount of the outstanding Securities of a series may be adopted at a meeting or an adjourned meeting duly reconvened and
at which a quorum is present as aforesaid by the affirmative vote of the Holders of such specified percentage in principal amount of the outstanding Securities of such series. 
 Any resolution passed or decision taken at any meeting of Holders of Securities of any series duly held in accordance with this Section 11.04 or other Act duly taken shall be binding on all the
Holders of Securities of such series, whether or not such Holders were present or represented at the meeting, if any. 
 Section 11.05.
DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT OF MEETINGS. 
 Notwithstanding any other provisions of this Indenture,
the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders of Securities of a series in regard to proof of the holding of Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall deem appropriate. Except as
otherwise permitted or required by any such regulations, the holding of Securities shall be proved in the manner specified in Section 1.05 and the appointment of any proxy shall be proved in the manner specified in Section 1.05. Such
regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in Section 1.05 or other proof. 

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 11.02(b), in which case the Company or the Holders of Securities of the series calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote at least a majority in principal amount of the outstanding Securities of such series represented at the meeting. 

Any meeting of Holders of Securities of any series duly called pursuant to Section 11.02 at which a quorum is present may be
adjourned from time to time by Persons entitled to vote at least a majority in principal amount of the outstanding Securities of such series represented at the meeting; and the meeting may be held as so adjourned without further notice. 

Section 11.06. COUNTING VOTES AND RECORDING ACTION OF MEETINGS. 
 The vote upon any resolution submitted to any meeting of Holders of Securities of any series shall be by written ballots on which shall be subscribed the signatures of the Holders of Securities of such
series or of their representatives by proxy and the principal amounts and serial numbers of the outstanding Securities of such series held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall
count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record, at


  
 - 52 -









 
least in duplicate, of the proceedings of each meeting of Holders of Securities of any series shall be prepared by the secretary of the meeting and there shall be attached to said record the
original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was given as provided
in Section 11.02 and, if applicable, Section 11.04. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Company, and another to the
Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated. 

Section 11.07. ARTICLE SUBJECT TO OTHER PROVISIONS. 
 Each provision of this Article 11 (whether or not expressly so stated) is subject to any other provision of this Indenture (or any supplemental indenture establishing a series of Securities hereunder)
that provides that Securities of different series constitute a single class. 
 ARTICLE 12. 

CONVERSION OF SECURITIES 

Section 12.01. APPLICABILITY OF ARTICLE. 
 The provisions of this Article shall be applicable to the Securities of any series which are convertible into shares of Common Stock of the Company, and the issuance of such shares of Common Stock upon
the conversion of such Securities, except as otherwise specified as contemplated by Section 2.02 for the Securities of such series. This Article shall not be applicable to Securities of any series which are not convertible into shares of Common
Stock of the Company. 
 Section 12.02. EXERCISE OF CONVERSION PRIVILEGE. 

(a) In order to exercise a conversion privilege, the Holder of a Security of a series with such a privilege must surrender such Security
to the Company at the office or agency maintained for that purpose pursuant to Section 4.02, accompanied by a duly executed Conversion Notice to the Company substantially in the form set forth on Exhibit B stating that the Holder elects to
convert such Security or a specified portion thereof. Such Conversion Notice shall also state, if different from the name and address of such Holder, the name or names (with address) in which the certificate or certificates for shares of Common
Stock which shall be issuable on such conversion shall be issued. Securities surrendered for conversion shall (if so required by the Company or the Trustee) be duly endorsed by, or accompanied by instruments of transfer satisfactory to the Company
and the Trustee duly executed by, the registered Holder or its attorney duly authorized in writing. 
 (b) To the extent
provided in Section 2.03(e), Securities surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date (except in the case of any
Security whose Maturity Date is prior to such Interest Payment Date) shall be accompanied by payment by such 

  
 - 53 -









 
Holder in immediately available funds to the Company of an amount equal to the interest to be received on such Interest Payment Date on the principal amount of the Securities being surrendered
for conversion. However, to the extent provided in Section 2.03(b), Securities which have been called for redemption on a redemption date or which are repurchasable on a redemption date that occurs between the close of business on a Regular
Record Date and the close of business on the Business Day immediately preceding such Interest Payment Date, shall not require such concurrent payment to the Company upon surrender for conversion, and, if such Securities are converted during the time
period set forth in the preceding sentence, the Holders of such converted Securities shall be entitled to receive (and retain) any accrued interest on the Principal amount of such surrendered Securities, if any. 

(c) To convert a Security a Holder must deliver to the Conversion Agent (i) a Conversion Notice, (ii) any payment required
pursuant to Section 12.02(b) or pursuant to and/or established in one or more indentures supplemental hereto setting forth the terms of such series of Security, (iii) any payment in respect of transfer or similar taxes, if required by
Section 12.07, and (iv) the Security duly endorsed in accordance with such reasonable regulations as the Company may prescribe. The date on which the Holder satisfies all of those requirements is the “Conversion Date” for
such Security. As soon as practicable after the Conversion Date, the Company shall issue and shall deliver or cause to be issued and delivered, at the office or agency at which such Security is surrendered, to such Holder or on its written order, a
certificate or certificates for the number of full shares of Common Stock issuable upon the conversion of such Security (or specified portion thereof), in accordance with the provisions of such supplemental indenture, and cash as provided therein in
respect of any fractional share of such Common Stock otherwise issuable upon such conversion. Except as set forth above and subject to Section 2.14, no payment or adjustment shall be made upon any conversion on account of any interest accrued
on the Securities (or any part thereof) surrendered for conversion or on account of any dividends on the Common Stock of the Company issued upon such conversion. The person in whose name the shares of Common Stock issued upon conversion is
registered shall be deemed to be a holder of record of such Common Stock on the Conversion Date; provided, however, that no surrender of a Security on any Conversion Date when the stock transfer books of the Company shall be closed shall be
effective to constitute the person or persons entitled to receive the shares of Common Stock upon conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the person
or persons thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; provided, further, that such conversion shall be at the conversion date in effect on the Conversion Date as
if the stock transfer books of the Company had not been closed. Upon conversion of a Security, such person shall no longer be a Holder of such Security. 
 In the case of any Security which is converted in part only, upon such conversion the Company shall execute and the Trustee shall authenticate and deliver to or on the order of the Holder thereof, at the
expense of the Company, a new Security or Securities of the same series, of authorized denominations, in aggregate principal amount equal to the unconverted portion of such Security. 

  
 - 54 -









 Section 12.03. NO FRACTIONAL SHARES. 

No fractional share of Common Stock of the Company shall be issued upon conversions of Securities of any series. If more than one
Security shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions
thereof to the extent permitted hereby) so surrendered. If, except for the provisions of this Section 12.03, any Holder of a Security or Securities would be entitled to a fractional share of Common Stock of the Company upon the conversion of
such Security or Securities, or specified portions thereof, the Company shall pay to such Holder an amount in cash equal to the current market value of such fractional share computed, (i) if such Common Stock is listed or admitted to unlisted
trading privileges on a national securities exchange, on the basis of the last reported sale price regular way on such exchange on the last trading day prior to the date of conversion upon which such a sale shall have been effected, or (ii) if
such Common Stock is not at the time so listed or admitted to unlisted trading privileges on a national securities exchange, on the basis of the average of the bid and asked prices of such Common Stock in the over-the-counter market, on the last
trading day prior to the date of conversion, as reported by the National Quotation Bureau, Incorporated or similar organization if the National Quotation Bureau, Incorporated is no longer reporting such information, or if not so available, the fair
market price as determined by the Board of Directors. For purposes of this Section 12.03, “trading day” means each Monday, Tuesday, Wednesday, Thursday and Friday other than any day on which the Common Stock is not traded on
the New York Stock Exchange, or if the Common Stock is not traded on the New York Stock Exchange, on the principal exchange or market on which the Common Stock is traded or quoted. 
 Section 12.04. ADJUSTMENT OF CONVERSION PRICE. 
 The conversion price of
Securities of any series that is convertible into Common Stock of the Company shall be adjusted for any stock dividends, stock splits, reverse stock splits, reclassifications, combinations or similar transactions in accordance with the terms of the
supplemental indenture or Board Resolutions setting forth the terms of the Securities of such series. 
 Whenever the conversion
price is adjusted, the Company shall compute the adjusted conversion price in accordance with terms of the applicable supplemental indenture and shall prepare an Officers’ Certificate setting forth the adjusted conversion price and showing in
reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be filed at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 4.02 and, if different, with the
Trustee. 
 Section 12.05. NOTICE OF CERTAIN CORPORATE ACTIONS. 
 In case: 
 (1) the Company shall declare a dividend (or any other distribution) on
its Common Stock payable otherwise than in cash out of its retained earnings, which would require an adjustment to the conversion price of the Securities; or 

  
 - 55 -









 (2) the Company authorizes the granting to the holders of all or substantially all of its
Common Stock of rights, options or warrants to subscribe for or purchase any shares of capital stock of any class or of any other rights; or 
 (3) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding shares of Common Stock), or of any consolidation, merger or share exchange to
which the Company is a party and for which approval of any shareholders of the Company is required, or of the sale of all or substantially all of the assets of the Company; 
 then the Company shall cause to be filed with the Trustee, and shall cause to be mailed to all Holders at their last addresses as they appear in the Securities Register, at least 20 days (or 10 days in
any case specified in Clause (1) or (2) above) prior to the applicable record date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such dividend, distribution, rights, options
or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights, options or warrants are to be determined, or (ii) the date on which such
reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their
shares of Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding up. If at any time the Trustee shall not be the Conversion Agent,
a copy of such notice shall also forthwith be filed by the Company with the Conversion Agent. Failure to give any such notice or any defect therein shall not affect the legality or validity of the proceedings described in clauses (1) through
(4) of this Section 12.05. 
 Section 12.06. RESERVATION OF SHARES OF COMMON STOCK. 

The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock,
for the purpose of effecting the conversion of Securities, the full number of shares of Common Stock of the Company then issuable upon the conversion of all outstanding Securities of any series that has conversion rights. 

Section 12.07. PAYMENT OF CERTAIN TAXES UPON CONVERSION. 
 Upon conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of shares of Common Stock upon the conversion. However, the Holder shall pay any withholding
tax or any tax that is due because the shares are issued in a name other than the Holder’s name. 
 Section 12.08. NONASSESSABILITY.

 The Company covenants that all shares of its Common Stock which may be issued upon conversion of Securities will upon issue
in accordance with the terms hereof be duly and validly issued and fully paid and nonassessable. 

  
 - 56 -









 Section 12.09. EFFECT OF CONSOLIDATION OR MERGER ON CONVERSION PRIVILEGE. 

In case of any consolidation of the Company with, or merger of the Company into or with any other Person, or in case of any sale of all
or substantially all of the assets of the Company, the company or the Person formed by such consolidation or the Person into which the Company shall have been merged or the Person which shall have acquired such assets, as the case may be, shall
execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then outstanding of any series that is convertible into Common Stock of the Company shall have the right, which right shall be the exclusive
conversion right thereafter available to said Holder (until the expiration of the conversion right of such Security), to convert such Security into the kind and amount of shares of stock or other securities or property (including cash) receivable
upon such consolidation, merger or sale by a holder of the number of shares of Common Stock of the Company into which such Security might have been converted immediately prior to such consolidation, merger or sale, subject to compliance with the
other provisions of this Indenture, such Security and such supplemental indenture. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in such Security.
The above provisions of this Section 12.09 shall similarly apply to successive consolidations, mergers or sales. It is expressly agreed and understood that anything in this Indenture to the contrary notwithstanding, if, pursuant to such merger,
consolidation or sale, holders of outstanding shares of Common Stock of the Company do not receive shares of common stock of the surviving corporation but receive other securities, cash or other property or any combination thereof, Holders of
Securities shall not have the right to thereafter convert their Securities into common stock of the surviving corporation or the corporation which shall have acquired such assets, but rather, shall have the right upon such conversion to receive the
other securities, cash or other property receivable by a holder of the number of shares of Common Stock of the Company into which the Securities held by such holder might have been converted immediately prior to such consolidation, merger or sale,
all as more fully provided in the first sentence of this Section 12.09. Anything in this Section 12.09 to the contrary notwithstanding, the provisions of this Section 12.09 shall not apply to a merger or consolidation of another
corporation with or into the Company pursuant to which both of the following conditions are applicable: (i) the Company is the surviving corporation and (ii) the outstanding shares of Common Stock of the Company are not changed or
converted into any other securities or property (including cash) or changed in number or character or reclassified pursuant to the terms of such merger or consolidation. 
 As evidence of the kind and amount of shares of stock or other securities or property (including cash) into which Securities may properly be convertible after any such consolidation, merger or sale, or as
to the appropriate adjustments of the conversion prices applicable with respect thereto, the Trustee shall be furnished with and may accept the certificate or opinion of an independent certified public accountant with respect thereto; and, in the
absence of bad faith on the part of the Trustee, the Trustee may conclusively rely thereon, and shall not be responsible or accountable to any Holder of Securities for any provision in conformity therewith or approved by such independent certified
accountant which may be contained in said supplemental indenture. 

  
 - 57 -









 Section 12.10. DUTIES OF TRUSTEE REGARDING CONVERSION. 

Neither the Trustee nor any Conversion Agent shall at any time be under any duty or responsibility to any Holder of Securities of any
series that is convertible into Common Stock of the Company to determine whether any facts exist which may require any adjustment of the conversion price, or with respect to the nature or extent of any such adjustment when made, or with respect to
the method employed, whether herein or in any supplemental indenture, any resolutions of the Board of Directors or written instrument executed by one or more officers of the Company provided to be employed in making the same. Neither the Trustee nor
any Conversion Agent shall be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock of the Company, or of any securities or property, which may at any time be issued or delivered upon the conversion
of any Securities and neither the Trustee nor any Conversion Agent makes any representation with respect thereto. Subject to the provisions of Section 7.01, neither the Trustee nor any Conversion Agent shall be responsible for any failure of
the Company to issue, transfer or deliver any shares of its Common Stock or stock certificates or other securities or property upon the surrender of any Security for the purpose of conversion or to comply with any of the covenants of the Company
contained in this Article 12 or in a supplemental indenture with respect to such Securities. 
 Section 12.11. REPAYMENT OF CERTAIN FUNDS
UPON CONVERSION. 
 Any funds which at any time have been deposited by the Company or on its behalf with the Trustee or any
other Paying Agent for the purpose of paying the principal of, and premium, if any, and interest, if any, on any of the Securities (including, but not limited to, funds deposited pursuant to Article 8 hereof) and which shall not be required for such
purposes because of the conversion of such Securities as provided in this Article 12 shall after such conversion be repaid to the Company by the Trustee upon the Company’s written request. 

Section 12.12. STOCKHOLDER RIGHTS PLAN. 
 If the Company has a stockholder rights plan in effect upon a conversion of any Security and the Company delivers any shares of Common Stock upon such conversion, the converting Holder shall receive, in
addition to such shares of Common Stock, the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any
stockholder rights plan adopted by the Company and in effect upon conversion of such Securities, as the same may be amended from time to time. Notwithstanding the foregoing, if prior to such conversion the rights have separated from the shares of
Common Stock in accordance with the provisions of the applicable stockholder rights agreement, the conversion rate with respect to such series shall be adjusted as provided in the supplemental indenture with respect to such series of Securities.

accordance with the Indenture and the terms of such Securities; (iv) failure by the Company to comply with its obligations under Section 5.01(a) and (b) and Section 5.02 of the Indenture; (v) failure by the Company to comply

amount of the Notes then outstanding and any other affected Securities outstanding under the Indenture (treating the Notes and such other series as a single class), in accordance with the Indenture; (vi) certain defaults with respect to the
Indebtedness of the Company or any of its Subsidiaries, as provided in the Indenture; (vii) one or more final, non-appealable judgments against the Company or any of its Subsidiaries, the aggregate uninsured portion of which is at least
$50,000,000, if such judgments are not paid or discharged within 120 days; and (viii) certain events of bankruptcy or insolvency with respect to the Company. In case an Event of Default shall have occurred and be continuing, the principal of
and interest on all Notes may be declared due and payable, by either the Trustee or Holders of not less than 25% in aggregate principal amount of Notes then outstanding and other series of Securities affected (treating the Notes and such other
series as a single class), and upon said declaration shall become due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture. Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency with respect to the Company, all outstanding Notes will become due and payable without further action or notice. Holders of the Notes may not enforce the Indenture or the Notes except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then-outstanding Notes and other series of Securities affected (treating the Notes and such other series as a single class) may direct the Trustee
in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines
that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes and other series of Securities affected (treating the Notes and such other series as a single class) and other series of Securities
affected (treating the Notes and such other series as a single class) then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes and such other Securities waive any existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of Default in the payment of principal, interest or premium, if any, on the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with
the Indenture.

 14. NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or stockholder of the Company will have any liability for any obligations of the Company under the Notes or the
Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the
