matters upon which his or her certificate, statement or opinion is based such matters are erroneous.

such a meeting of Holders or (d) in the case of Securities evidenced by a Global Security, by any electronic transmission or other message, whether or not in written format, that complies with the Depositary’s applicable procedures. Such
evidence (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the relevant Holders. Proof of execution of any such instrument or of a writing appointing any such agent or proxy shall be
sufficient for any purpose of this Indenture and (subject to Section 6.01) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. 
 (2) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution
or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a
signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the
Person executing the same, may also be proved in any other manner that the Trustee deems sufficient.

 (5)
The Company may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action
provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series, provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the
requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been
set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by
Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of
such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.06. The Trustee may set any
day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in
Section 5.02, (iii) any request to institute proceedings referred to in Section 5.07(2) or (iv) any direction referred to in Section 5.12, in each case with respect to Securities of such series. If any record date is
set pursuant to this paragraph, the Holders of Outstanding Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders
after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date.
Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the
relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.06. 
 (6) With respect to any record date set pursuant to this Section, the party hereto which sets such record dates may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to
any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in the manner set
forth in Section 1.06, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto which set such record date shall be deemed to have
initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later
than the 180th day after the applicable record date. 
 (7) Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all
or any part of such principal amount.

 Section 1.05 Notices, Etc., to Trustee and the Company. Any request, demand, authorization, direction,
notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with: 
 (1) the Trustee by any Holder or by the Company or any Subsidiary Guarantor shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing in the English language to or with the Trustee at its
Corporate Trust Office, Attention: Corporate Trust Services; or 
 (2) the Company or any Subsidiary Guarantor by the Trustee or by any
Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing in the English language and mailed, first-class postage prepaid, in the case of the Company addressed to it at the address of its
principal office specified in the first paragraph of this instrument, Attention: Chief Financial Officer, or at any other address previously furnished in writing to the Trustee by the Company and, in the case of any Subsidiary Guarantor, to it at

 Section 1.06 Notice to Holders; Waiver. Where this Indenture or any Security provides for notice to Holders of any event, such notice shall
be deemed sufficiently given (unless otherwise herein or in such Security expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register,
not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders or the validity of the proceedings to which such notice relates. Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not
be a condition precedent to the validity of any action taken in reliance upon such waiver. In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 
 Section 1.07
Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act which is required under such Act to be a part of and govern this Indenture, such required provision shall
control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act which may be so modified or excluded, such latter provision of the Trust Indenture Act shall be deemed to apply to this Indenture as so
modified or shall be excluded, as the case may be. 
 Section 1.08 Effect of Headings and Table of Contents. The Article and
Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. 
 Section 1.09
Successors and Assigns. All covenants and agreements in this Indenture by the Company and any Subsidiary Guarantor shall bind its respective successors and assigns, whether so expressed or not. 
 Section 1.10 Separability Clause. In case any provision in this Indenture, the Securities or the Subsidiary Guarantees shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 Section
1.11 Benefits of Indenture. Nothing in this Indenture, the Securities or the Subsidiary Guarantees, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder, the Holders and, to the extent
specifically set forth herein, the holders of Senior Debt, any benefit or any legal or equitable right, remedy or claim under this Indenture.

 Section 1.13 Legal
Holidays. In any case where any Interest Payment Date, sinking fund payment, Redemption Date, purchase date or Stated Maturity or Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other
provision of this Indenture or of the Securities (other than a provision in the Securities of any series which specifically states that such provision shall apply in lieu of this Section) payment of interest or principal (and premium and any other
amounts, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day or on such other day as may be set out in the Officers’ Certificate pursuant to Section 3.01 or in any
supplemental indenture with respect to the Securities at such Place of Payment with the same force and effect as if made on the Interest Payment Date, Redemption Date, provided that no interest shall accrue on the amount so payable for the period
from and after such Interest Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or Maturity, as the case may be, if payment is made on such next succeeding Business Day or other day set out in such Officers’ Certificate
or in any supplemental indenture with respect to the Securities. 
 Section 1.14 No Recourse Against Others. A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each
Securityholder, by accepting a Security, waives and releases all such liability. Such waivers and releases are part of the consideration for the issuance of the Securities.

             and              in each year [if other than semi-annual payments, insert frequency of payments and
payment dates], commencing             , at [if the Security is to bear interest at a fixed rate, insert the rate of     % per annum], [if the Security is

such installment of interest, which is overdue shall bear interest at the rate of % per annum (to the extent that the payment of such interest shall be legally enforceable), from the dates such amounts are due until they are paid or made available
for payment, and such interest shall be payable on demand. The interest so payable, and promptly paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one
or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the              or
             (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest not so promptly paid or duly provided for will
forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the
payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. 
 [If the Securities are floating or adjustable rate securities with respect to which the principal of or any premium, other amounts or interest may be determined
with reference to an index, insert the text of the floating or adjustable rate provisions.] Interest will be computed on the basis of a 360 day year of twelve 30 day months. 
 [If the Security is not to bear interest prior to Maturity, insert — .] The principal of this Security shall not bear interest except in the case of a default
in payment of principal upon acceleration, upon redemption or at Stated Maturity and in such case the overdue principal of this Security and any overdue premium on this Security shall bear interest at the rate of     % per
annum (to the extent that the payment of such interest shall be legally enforceable), from the dates such amounts are due until they are paid or made available for payment. Interest on any overdue principal or premium shall be payable on demand. Any
such interest on overdue principal or premium which is not paid on demand shall bear interest at the rate of     % per annum (to the extent that the payment of such interest on interest shall be legally enforceable), from
the date of such demand until the amount so demanded is paid or made available for payment. Interest on any overdue interest shall be payable on demand.] 
 Payment of the principal of (and premium, if any) and [if applicable, insert — any such] interest on this Security will be made at the office or agency of the Company maintained for that purpose in
            , in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at
the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. 
 [If applicable, insert — So long as all of the Securities of this series are represented by Securities in global form, the principal of, premium and other
amounts, if any, and interest, if any, on this global Security shall be paid in same day funds to the Depositary, or to such name or entity as is requested by an authorized representative of the Depositary. If at any time the Securities of this
series are no longer represented by global Securities and are issued in definitive certificated form, then the principal of, premium and other amounts, if any, and interest, if any, on each certificated Security at Maturity shall be paid in same day
funds to the Holder upon surrender of such certificated Security at the Corporate Trust Office of the Trustee, or at such other place or places as may be designated in or pursuant to the Indenture, provided that such certificated Security is
surrendered to the Trustee, or at such other place or places as may be designated in or pursuant to the Indenture, provided that such certificated Security is surrendered to the trustee, acting as Paying Agent, in time for the Paying Agent to make
such payments in such funds in accordance with its normal procedures. Payments of interest with respect to such certificated Securities other than at Maturity may, at the option of the Company, be made by check mailed to the address of the Person
entitled thereto as it appears on the Security Register on the relevant Regular or Special Record Date or by wire transfer in same day funds to such account as may have been appropriately designated to the Paying Agent by such Person in writing not
later than such relevant Regular or Special Record Date.]

any premium or interest hereon on or after the respective due dates expressed herein. 
 No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency,

 Section 2.04 Form of Subsidiary
Guarantee. 
 SUBSIDIARY GUARANTEE 
 For value
received, each of the Subsidiary Guarantors named (or deemed herein to be named) below hereby jointly and severally fully and unconditionally guarantees to the Holder of the Security upon which this Subsidiary Guarantee is endorsed, and to the
Trustee on behalf of such Holder, the due and prompt payment of the principal of (and premium, if any) and interest on such Security when and as the same shall become due and payable, whether at the Stated Maturity, by acceleration, call for
redemption or otherwise, according to the terms thereof and of the Indenture referred to therein and to cover all the rights of the Trustee under Section 6.07. In case of the failure of the Company promptly to make any such payment, each of the
Subsidiary Guarantors hereby jointly and severally agrees to cause such payment to be made promptly when and as the same shall become due and payable, whether at the Stated Maturity or by acceleration, call for redemption or otherwise, and as if
such payment were made by the Company. 
 Each of the Subsidiary Guarantors hereby jointly and severally agrees that its obligations hereunder shall be
absolute and unconditional, irrespective of, and shall be unaffected by, the validity, regularity or enforceability of such Security or the Indenture, the absence of any action to enforce the same or any release, amendment, waiver or indulgence
granted to the Company or any other guarantor, or any consent to departure from any requirement of any other guarantee of all or of any of the Securities of this series, or any other circumstances which might otherwise constitute a legal or
equitable discharge or defense of a surety or guarantor; provided, however, that, notwithstanding the foregoing, no such release, amendment, waiver or indulgence shall, without the consent of such Subsidiary Guarantor, increase the principal amount
of such Security, or increase the interest rate thereon, or alter the Stated Maturity thereof. Each of the Subsidiary Guarantors hereby waives the benefits of diligence, presentment, demand of payment, any requirement that the Trustee or any of the
Holders protect, secure, perfect or insure any security interest in or other lien on any property subject thereto or exhaust any right or take any action against the Company or any other Person or any collateral, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest or notice with respect to such Security or the indebtedness evidenced thereby and all demands whatsoever, and covenants that this
Subsidiary Guarantee will not be discharged except by complete performance of the obligations contained in such Security and in this Subsidiary Guarantee. Each Subsidiary Guarantor agrees that if, after the occurrence and during the continuance of
an Event of Default with respect to Securities of this series, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Securities of this series, to collect interest
on the Securities of this series, or to enforce or exercise any other right or remedy with respect to the Securities of this series, such Subsidiary Guarantor agrees to pay to the Trustee for the account of the Holders, upon demand therefor, the
amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders. 
 No reference herein to the Indenture and no provision of this Subsidiary Guarantee or of the Indenture shall alter or impair the Subsidiary Guarantee of any Subsidiary Guarantor, which is absolute and unconditional, of the due and prompt
payment of the principal (and premium, if any) and interest on the Security upon which this Subsidiary Guarantee is endorsed. 
  

 18 








 Each Subsidiary Guarantor shall be subrogated to all rights of the Holder of this Security against the Company in
respect of any amounts paid by such Subsidiary Guarantor on account of this Security pursuant to the provisions of its Subsidiary Guarantee or the Indenture; provided, however, that such Subsidiary Guarantor shall not be entitled to enforce or to
receive any payments arising out of, or based upon, such right of subrogation until the principal of (and premium, if any) and interest on this Security and all other Securities of this series issued under the Indenture shall have been paid in full.

 This Subsidiary Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Company
for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any part of the Company’s assets, and shall, to the fullest extent
permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Securities of this series is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or
returned by any Holder of the Securities of this series, whether as a “voidable preference,” “fraudulent transfer,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any
part thereof, is rescinded, reduced, restored or returned, the Securities of this series shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

 The Subsidiary Guarantors or any particular Subsidiary Guarantor shall be released from this Subsidiary Guarantee upon the terms and subject to
certain conditions provided in the Indenture. 
 By delivery to the Trustee of a supplement to the Indenture referred to in the Security upon which
this Subsidiary Guarantee is endorsed in accordance with the terms of the Indenture, each Person that becomes a Subsidiary Guarantor after the date of first issuance of the Securities of this series will be deemed to have executed and delivered this
Subsidiary Guarantee for the benefit of the Holder of the Security upon which this Subsidiary Guarantee is endorsed with the same effect as if such Subsidiary Guarantor was named below and has executed and delivered this Subsidiary Guarantee.

 All terms used in this Subsidiary Guarantee which are defined in the Indenture shall have the meanings assigned to them in such Indenture.

 This Subsidiary Guarantee shall not be valid or obligatory for any purpose until the certificate of authentication on the Security upon which this
Subsidiary Guarantee is endorsed shall have been executed by the Trustee under the Indenture by manual signature. 
 Reference is made to the Indenture
for further provisions with respect to this Subsidiary Guarantee. 
 This Subsidiary Guarantee shall be governed by and construed in accordance with
the laws of the State of New York without regard to conflict of law principles. 
 IN WITNESS WHEREOF, each of the Subsidiary Guarantors has caused
this Subsidiary Guarantee to be duly executed.

to the Board Resolution referred to above and (subject to Section 3.03) set forth, or determined in the manner provided, in the Officers’ Certificate referred to above or in any such indenture supplemental hereto. All Securities of any 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. 
  

 23 








 If any of the terms of the Securities of any series are established by action taken pursuant to a Board Resolution,
a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth the terms of the
series. 
 The Securities of each series shall have the benefit of the Subsidiary Guarantees unless the Company elects otherwise upon the establishment
of a series pursuant to this Section 3.01. 
 Section 3.02 Denominations. The Securities of each series shall be issuable only in
registered form without coupons and only in such denominations as shall be specified as contemplated by Section 3.01. In the absence of any such specified denomination with respect to the Securities of any series, the Securities of such series
shall be issuable in denominations of $1,000 and any integral multiple thereof. 
 Section 3.03 Execution, Authentication, Delivery and Dating.
The Securities shall be executed on behalf of the Company by its President, Chief Executive Officer, its Chief Financial Officer or its Chief Operating Officer. The Securities shall be attested by the Company’s Secretary, one of its Assistant
Secretaries, its Treasurer or one of its Assistant Treasurers. The signature of any of these officers on the Securities may be manual or facsimile. Typographical and other minor errors or defects in any such reproduction of the seal or any such
signature shall not affect the validity or enforceability of any Security that has been duly authenticated and delivered by the Trustee. 
 Securities
bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of such Securities or did not hold such offices at the date of such Securities. 
 At any time and from time to time after
the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company and, if applicable, having endorsed thereon the Subsidiary Guarantees executed as provided in Section 13.03 by the Subsidiary
Guarantors to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and make such Securities available for
delivery. If the form or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by Sections 2.01 and 3.01, in authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the Trustee shall receive, and (subject to Section 6.01) shall be fully protected in relying upon, an Opinion of Counsel stating (subject to customary assumptions,
conditions and exceptions) 
 (1) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by
Section 2.01, that such form has been established in conformity with the provisions of this Indenture; 
 (2) if the terms of such
Securities have been established by or pursuant to Board Resolution as permitted by Section 3.01, that such terms have been established in conformity with the provisions of this Indenture; and 
 (3) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions
specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, and, if applicable, the Subsidiary Guarantees endorsed thereon will constitute valid and legally binding obligations of the Subsidiary
Guarantors, enforceable in accordance with their terms, except to the extent enforceability may be limited by applicable bankruptcy, insolvency, fraudulent transfer, fraudulent conveyance, reorganization, moratorium and similar laws of general
applicability relating to or affecting the enforcement of creditors’ rights and by the effect of general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity. 
  

 24 








 If such form or terms have been so established, the Trustee shall not be required to authenticate such Securities
if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

 Notwithstanding the provisions of Section 3.01 and of the immediately preceding paragraph, if all Securities of a series are not to be
originally issued at one time, it shall not be necessary to deliver the Board Resolution and the Officers’ Certificate otherwise required pursuant to Section 3.01 or the Company Order and Opinion of Counsel otherwise required pursuant to
the second preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the time of authentication upon original issuance of the first Security of such series to be issued. If
the Company shall establish pursuant to Section 3.01 that the Securities of a series are to be issued in whole or in part in the form of one or more global Securities, then the Company shall execute and the Trustee shall, in accordance with
this Section and the Company Order with respect to the authentication and delivery of such series, authenticate and deliver one or more Securities of such series in global form that (i) shall be in an aggregate amount equal to the
aggregate principal amount of the Outstanding Securities of such series to be represented by such Security or Securities in global form, (ii) shall be registered in the name of the Depositary for such Security or Securities in global form or
its nominee, and (iii) shall be made available for delivery by the Trustee to such Depositary or pursuant to such Depositary’s instruction. 
 If all the Securities of any one series are not to be issued at one time and if a Board Resolution relating to such Securities shall so permit, the Company Order may set forth procedures acceptable to the Trustee for the issuance of such
Securities, including, without limitation, procedures with respect to interest rate, Stated Maturity, date of issuance and date from which interest, if any, shall accrue. 
 Each Security shall be dated the date of its authentication. 
 No Security or Subsidiary Guarantee shall be entitled to any
benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee or an Authenticating Agent by manual
signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. 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 3.09, 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. 
 In case any Securities shall have been authenticated, but not delivered, by the Trustee or the Authenticating Agent for such series then in office, any successor by merger, conversion or consolidation to such Trustee, or any
successor Authenticating Agent, as the case may be, may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee or successor Authenticating Agent had itself authenticated such
Securities. Each Depositary designated pursuant to Section 3.01 for a Security in global form must, at the time of its designation and at all times while it serves as Depositary, be a clearing agency registered under the Exchange Act and any
other applicable statute or regulation. 
 Section 3.04 Temporary Securities. Pending the preparation of definitive Securities of any series,
the Company may execute, and upon Company Order the Trustee shall authenticate and make available for delivery, temporary Securities of such series which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities and, if applicable, having endorsed thereon the Subsidiary Guarantees in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Securities and, if applicable, Subsidiary Guarantees may determine, as evidenced by their execution of such Securities and Subsidiary Guarantees. 
 In the case of Securities of any series, such temporary Securities may be in global form, representing all or a portion of the Outstanding Securities of such
series. 
  

 25 








 If temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be
prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of
such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee
shall authenticate and make available for delivery in exchange therefore one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount and, if applicable, having endorsed
thereon Subsidiary Guarantees executed by the Subsidiary Guarantors. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and
tenor. 
 Section 3.05 Registration, Registration of Transfer and Exchange. The Company shall cause to be kept at the Corporate Trust Office of
the Trustee or in any office or agency to be maintained by the Company in accordance with Section 10.02 in a Place of Payment a register (the register maintained in such office and in any other office or agency of the Company in a Place of
Payment being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of
Securities. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided. 
 Upon surrender for registration of transfer of any Security of a series at the office or agency of the Company in a Place of Payment for that series, the Company shall execute, if applicable the Subsidiary Guarantors shall
execute the Subsidiary Guarantees endorsed thereon and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of like
tenor and aggregate principal amount. 
 At the option of the Holder, Securities of any series may be exchanged for other Securities of the same
series, of any authorized denominations and of like tenor and aggregate principal amount, 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,
if applicable the Subsidiary Guarantors shall execute the Subsidiary Guarantees endorsed thereon and the Trustee shall authenticate and make available for delivery, the Securities which the Holder making the exchange is entitled to receive.

 All Securities and, if applicable, the Subsidiary Guarantees endorsed thereon issued upon any registration of transfer or exchange of Securities
shall be the valid obligations of the Company and, if applicable, the respective Subsidiary Guarantors, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities and Subsidiaries Guarantees surrendered upon
such registration of transfer or exchange. 
 Every Security presented or surrendered for registration of transfer or for exchange shall (if so
required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized
in writing. 
 No service charge shall be made for any registration of transfer or exchange of Securities, but the Company or the Trustee may require
payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.04, 9.06, 11.07 or otherwise not
involving any transfer. 
 If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be
required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the
mailing of a notice of redemption of any such Securities selected for redemption under Section 11.03 and ending at the close of business on the day of such mailing, or (B) 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. The provisions of clauses (1), (2), (3) and (4) below shall apply only to Global Securities: 
  

 26 








 (1) Each Global Security authenticated under this Indenture shall be registered in the name of the
Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefore, and each such Global Security shall constitute a single Security for all purposes of this Indenture.

 (2) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for Securities
registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (A) such Depositary (i) has notified the
Company that it is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act, and in either case the Company fails to appoint a successor Depositary
within 90 days, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security and the Depositary shall have notified the Trustee of its decision to exchange such Global Security for Securities in
certificated form or (C) there shall exist such circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this purpose as contemplated by Section 3.01. 
 (3) Subject to clause (2) above, any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities
issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct. 
 (4) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 3.04, 3.06, 9.06 or
11.07 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof. 

Section 3.06 Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee, the Company shall execute, if
applicable the Subsidiary Guarantors shall execute the Subsidiary Guarantees endorsed thereon and the Trustee shall authenticate and deliver in exchange therefore a new Security of the same series and of like tenor and principal amount and bearing a
number not contemporaneously outstanding. If required by the Trustee and 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. 
 If there shall be delivered to the Company and the
Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless from any loss that
any of them may suffer if a Security is replaced, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute, if applicable the Subsidiary Guarantors shall
execute the Subsidiary Guarantees endorsed thereon and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding. 
 In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable
or is to be converted, the Company in its discretion may, instead of issuing a new Security, pay or authorize the conversion of such Security (without surrender thereof save in the case of a mutilated Security). 
 Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge
that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
 Every new
Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security, and, if applicable, the Subsidiary Guarantees endorsed thereon, shall constitute an original additional contractual obligation of the
Company and, if applicable, the respective Subsidiary Guarantors, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of that series duly issued hereunder. 
  

 27 








 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement, payment or conversion of mutilated, destroyed, lost or stolen Securities. 
 Section 3.07 Payment of
Interest; Interest Rights Preserved. Except as otherwise provided as contemplated by Section 3.01 with respect to any series of Securities, interest on any Security which is payable, and is promptly paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. 
 Any interest on any Security of any series which is payable, but is not promptly paid or duly provided for, on any Interest Payment Date (herein called
“Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below: 
 (1) The Company may elect to make payment of any Defaulted Interest to the Persons in
whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of
money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements reasonably satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to
be held in trust for the benefit of the Persons entitled to such Defaulted Interest as provided in this clause. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and
not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the
name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section 1.06,
not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the
Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). 
 (2) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the
requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause (2), such
manner of payment shall be deemed practicable by the Trustee. 
 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 3.08 Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Subsidiary Guarantors, the Trustee
and any agent of the Company, the Subsidiary Guarantors, or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to
Section 3.07) any interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and none of the Company, any Subsidiary Guarantor, the Trustee or any agent of the Company, any Subsidiary Guarantor, or
the Trustee shall be affected by notice to the contrary. 
 None of the Company, the Trustee or any agent of the Company or the Trustee shall have any
responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interest of a Security in global form, or for maintaining, supervising or reviewing any records relating to such beneficial


  

 28 








 
ownership interest. Notwithstanding the foregoing, with respect to any Security in global form, nothing herein shall prevent the Company or the Trustee or any agent of
the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by any Depositary (or its nominee), as a Holder, with respect to such Security in global form or impair, as between such Depositary
and owners of beneficial interests in such Security in global form, the operation of customary practices governing the exercise of the right of such Depositary (or its nominee) as holder of such Security in global form. 
 Section 3.09 Cancellation. All Securities surrendered for payment, redemption, purchase, registration of transfer or exchange or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. A copy of all cancelled Securities shall be delivered to the Company. 
 Section 3.10 Computation
of Interest. Except as otherwise specified as contemplated by Section 3.01 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. 
 Section 3.11 CUSIP Number. The Company in issuing Securities of any series may use a “CUSIP” number, and if so, the Trustee may use the CUSIP
number in notices of redemption or exchange as a convenience to Holders of such series; provided, that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed on the notice or on the
Securities of such series, and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly
notify the Trustee of any change in the CUSIP number of any series of Securities. 
 Section 3.12 Wire Transfers. Notwithstanding any other
provision to the contrary in this Indenture, the Company may make any payment of moneys required to be deposited with the Trustee on account of principal of, or premium, if any, or interest on the Securities (whether pursuant to optional or
mandatory redemption payments, interest payments or otherwise) by wire transfer of immediately available funds to an account designated by the Trustee on or before the date and time such moneys are to be paid to the Holders of the Securities in
accordance with the terms hereof. 
 ARTICLE 4 
 SATISFACTION AND DISCHARGE 
 Section 4.01 Satisfaction and Discharge of Indenture. This Indenture shall upon Company Request
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 
 (1) Either 
 (A) all Securities of
such series theretofore authenticated and delivered (other than (i) Securities of such series which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 3.06 and (ii) Securities of such
series for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 10.03) have been delivered to the
Trustee for cancellation; or 
 (B) all such Securities of such series not theretofore delivered to the Trustee for cancellation

  

 29 








 (i) have become due and payable, or 
 (ii) will become due and payable at their Stated Maturity within one year, or 
 (iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the
Trustee in the name, and at the expense, of the Company, 
 and the Company or, if applicable, a Subsidiary Guarantor, in the case of (i), (ii) or
(iii) above, has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose money in an amount sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire
indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal and any premium and interest 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 
 (2) the Company or a Subsidiary Guarantor has paid or caused to be paid all
other sums payable hereunder by the Company and has delivered irrevocable instructions to the Trustee to apply the deposited amounts to the payment of such Securities at Stated Maturity or redemption, as applicable: the Subsidiary Guarantors with
respect to the Securities of such series; and 
 (3) no Default or Event of Default with respect to this Indenture or the Securities
shall have occurred on the date of deposit and such deposit will not result in a breach or violation of, or constitute a default under, any other instruments to which the Company is a party or to which it is bound; and 
 (4) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent
provided for herein relating to the satisfaction and discharge of this Indenture with respect to the Securities of such series have been complied with; and 
 (5) no event or condition shall exist on the date of such deposit that, pursuant to the provisions of Section 16.02 or 16.03, would prevent the Company from making payments of the principal of or interest on the Securities
of such series on the date of such deposit. 
 Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the
Trustee under Section 6.07, any surviving rights of conversion, the obligations of the Company to any Authenticating Agent under Section 6.14 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause
(1) of this Section, the obligations of the Trustee under Section 4.02 and the last paragraph of Section 10.03 shall survive. 
 Section
4.02 Application of Trust Money. Subject to the provisions of the last paragraph of Section 10.03, all money deposited with the Trustee pursuant to Section 4.01 shall be held in trust and applied by it, in accordance with the
provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal and
any premium and interest for whose payment such money has been deposited with the Trustee. 
 Section 4.03 Reinstatement. If the Trustee or
Paying Agent is unable to apply any cash in accordance with this Article 4 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Article 4 until such time as the Trustee or Paying Agent is permitted to apply all such
cash in accordance with Article 4; provided, however, that if the Company has made any payment of interest on, premium and other amounts, if any, principal or other amounts, if any, of any Securities because of 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.

its obligations with respect to a specific series of Securities under this Indenture by complying with the terms of Article 4. If the Company makes such election, (a) the terms of Sections 4.01, 4.02 and 4.03 shall apply only to the specific
series of Securities and the terms of this Indenture as it relates to such series of Securities and (b) the other Securities issued hereunder and this Indenture as it relates to such other Securities shall remain in full force and effect.

inability to pay its or their debts generally as they become due, or the taking of corporate action by the Company, any Significant Subsidiary or any such Subsidiary Guarantor in furtherance of any such action; or 
 (7) in the event the Subsidiary Guarantors have issued Subsidiary Guarantees with respect to the Securities of such series, the Subsidiary Guarantee
of any Subsidiary Guarantor is held by a final non-appealable order or judgment of a court of competent jurisdiction to be unenforceable or invalid or ceases for any reason to be in full force and effect (other than in accordance with the terms of
this Indenture) or any Subsidiary Guarantor or any Person acting on behalf of any Subsidiary Guarantor denies or disaffirms such Subsidiary Guarantor’s obligations under its Subsidiary Guarantee (other than by reason of a release of such
Subsidiary Guarantor from its Subsidiary Guarantee in accordance with the terms of this Indenture); or 
 (8) any other Event of Default
provided in any indentures supplemental to this Indenture with respect to Securities of that series. 
 Section 5.02 Acceleration of Maturity;
Rescission and Annulment. If an Event of Default (other than an Event of Default with respect to the Company specified in Section 5.01(5) or 5.01(6)) with respect to Securities of any series at the time Outstanding occurs and is continuing,
then in every such case the Trustee by notice in writing to the Company or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series then Outstanding by notice in writing to the Company and the Trustee may
declare the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) to be
due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable. If an Event of Default
with respect to the Company specified in Section 5.01(5) or 5.01(6) with respect to Securities of any series at the time Outstanding occurs, the principal amount of all the Securities of that series (or, if any Securities of that series are
Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become
immediately due and payable. 
 Upon payment of all such principal and interest, all of the Company’s obligations under the Securities of that
series shall terminate and upon payment of the Securities of all series this Indenture shall terminate in either case, except those obligations under Section 6.07. 
 At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided
in this Article, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if 
 (1) the Company or, if applicable, any Subsidiary Guarantor has paid or deposited with the Trustee a sum sufficient to pay 
 (A) all overdue interest on all Securities of that series, 
 (B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of
acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities, 
  

 32 








 (C) to the extent that payment of such interest is lawful, interest upon overdue interest at the
rate or rates prescribed therefor in such Securities, and 
 (D) all sums paid or advanced by the Trustee hereunder and the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and 
 (2) all Events of Default with respect
to Securities of that series, other than the non-payment of the principal of Securities of that series which has become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13. 
 No such rescission shall affect any subsequent default or impair any right consequent thereon. 
 Section 5.03 Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if: 
 (1) default is made in the payment of any interest on any Security of any series when such interest becomes due and payable and such default
continues for a period of 30 days, or 
 (2) default is made in the payment of the principal of (or premium, if any, on) any Security of
any series at the Maturity thereof or upon redemption, or 
 (3) default is made in the payment of any sinking or analogous obligation
when the same becomes due by the terms of the Securities of any series, and any such default continues for any period of grace provided with respect to the Securities of such series, 
 the Company will, 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 such Securities for principal and any premium and interest and, to the extent
that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its
rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or
agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 
 Section 5.04 Trustee
May File Proofs of Claim. In case of any judicial proceeding relative to the Company, any Subsidiary Guarantor or any other obligor on the Securities, or the property or creditors of the Company, any Subsidiary Guarantor or any other obligor on
the Securities, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any
such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders,
to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.07. 
 No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities or any Subsidiary Guarantee 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;
provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee. 
  

 33 








 Section 5.05 Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims
under this Indenture or the Securities or any Subsidiary Guarantee may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such 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 of the Securities in respect of which such judgment has been recovered. 
 Section 5.06
Application of Money Collected. Any money collected by the Trustee pursuant to this Article in respect of the Securities of any series shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money on account of principal or any premium or interest, upon presentation of the Securities in respect of which moneys have been collected and the notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid: 
 FIRST: To the payment of all amounts due the Trustee under Section 6.07 applicable to the Securities of such series;

 SECOND: To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Securities of such series in respect
of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and any premium and interest, respectively; and

 THIRD: The balance, if any, to the Company. 
 The
Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 5.06. At least ten (10) days before such record date, the Trustee shall mail to each Holder and the Company a notice that states the record
date, the payment date and the amount to be paid. 
 Section 5.07 Limitation on Suits. No Holder of any Security of any series shall have any
right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 
 (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series;

 (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request
to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
 (3) such Holder or
Holders have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; 
 (4) the Trustee for 60 days after its receipt of such notice, request and offer of security or indemnity has failed to institute any such
proceeding; and 
 (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by
the Holders of a majority in principal amount of the Outstanding Securities of that series; it being understood and intended that no one or more of such 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 of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders of Securities of the affected series. 
  

 34 








 Section 5.08 Unconditional Right of Holders to Receive Principal, Premium and Interest. Notwithstanding any
other provision in this Indenture, but subject to Article 16, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 3.07) interest on
such Security on the respective Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and, if applicable, to convert such Security in accordance with its terms, and to institute suit
for the enforcement of any such right, and such rights shall not be impaired without the consent of such Holder. 
 Section 5.09 Restoration of
Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the
Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Subsidiary Guarantors, the Trustee and the Holders shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
 Section 5.10 Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.06, no right or remedy
herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right
or remedy. 
 Section 5.11 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Securities to exercise any
right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 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, as the case may be. 
 Section
5.12 Control by Holders. The Holders of a majority in principal amount of the Outstanding Securities of any series 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 that 
 (1) such
direction shall not be in conflict with any rule of law or with this Indenture or any supplemental indenture relating to such Securities; and 
 (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 
 Section 5.13
Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect
to such series and its consequences, except a default 
 (1) in the payment of the principal of or any premium or interest on any
Security of such series (including any Security which is required to have been redeemed by the Company pursuant a redemption notice issued by the Company made pursuant to the terms of this Indenture), or 
 (2) in respect of a covenant or provision hereof which under Article 9 cannot be modified or amended without the consent of the Holder of each
Outstanding Security of such series. 
  

 35 








 Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed
to have been cured, for every purpose of this Indenture and the Securities of such series; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 
 Section 5.14 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any
action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent
provided in the Trust Indenture Act; provided, however, that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the
Trustee, the Company or any Subsidiary Guarantor. 
 Section 5.15 Waiver of Usury, Stay or Extension Laws. Each of the Company and the
Subsidiary Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and each of the Company and the Subsidiary Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

 ARTICLE 6 
 THE TRUSTEE 
 Section 6.01 Certain Duties and Responsibilities. The duties and responsibilities of the Trustee shall be as expressly set forth in this Indenture and as
provided by the Trust Indenture Act. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 
 Section 6.02 Notice of Defaults. Within 90 days after the occurrence of any Default or Event of Default with respect to the Securities of any series, the
Trustee shall give to all Holders of Securities of such series, as their names and addresses appear in the Security Register, notice of such Default or Event of Default known to the Trustee, unless such Default or Event of Default shall have been
cured or waived; provided, however, that, except in the case of a Default or Event of Default in the payment of the principal of or premium, other amounts, if any, or interest on any Security of such series, or in the deposit of any sinking fund
payment with respect to Securities of that series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or responsible officers of the
Trustee in good faith determine that the withholding of such notice is in the interest of the Holders of Securities of such series. 
 Section 6.03
Certain Rights of Trustee. Subject to the provisions of Section 6.01: 
 (1) the Trustee may rely and shall be protected in
acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document reasonably
believed by it to be genuine and to have been signed or presented by the proper party or parties; 
 (2) any request or direction of the
Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order, and any resolution of the Board of Directors of the Company shall be sufficiently evidenced by a Board Resolution; 
  

 36 








 (3) whenever in the administration of this Indenture the Trustee shall deem it desirable that a
matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’
Certificate; 
 (4) the Trustee may consult with counsel of its selection and the written advice of such counsel or any Opinion of
Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 
 (5) 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 pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such request or
direction; 
 (6) prior to the occurrence of an Event of Default with respect to the Securities of any series and after the curing or
waiving of all such Events of Default which may have occurred, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request,
direction, consent, order, approval, or other paper or document, or the books and records of the Company, unless requested in writing to do so by the Holders of a majority in principal amount of the Outstanding Securities of any series; provided,
however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is not, in the opinion of the Trustee, reasonably assured to the Trustee by
the security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such costs, expenses or liabilities as a condition to so proceeding; the reasonable expense of every such investigation shall be paid by
the Company or, if paid by the Trustee, shall be repaid by the Company upon demand; 
 (7) the Trustee may execute any of the trusts or
powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it
hereunder; 
 (8) the Trustee shall not be required to expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk of liability is not reasonably assured to
it; 
 (9) except with respect to Section 10.01, the Trustee shall have no duty to inquire as to the performance of the Company
with respect to the covenants contained in Article 10. In addition, the Trustee shall not be deemed to have knowledge of an Event of Default except (i) any Default or Event of Default occurring pursuant to Sections 10.01, 5.01(1) or
5.01(2) or (ii) any Default or Event of Default of which the Trustee shall have received written notification or obtained actual knowledge; 
 (10) in no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the
Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action; 
 (11) the rights, privileges,
protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other
Person employed to act hereunder; 
 (12) the Trustee shall not be required to give any bond or surety in respect of the performance of
its powers and duties hereunder; and 
  

 37 








 (13) the Trustee may request that the Company deliver a certificate setting forth the names of
individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture. 
 Section 6.04 Not Responsible
for Recitals or Issuance of Securities. The recitals contained herein and in the Securities and the Subsidiary Guarantees, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company or the
Subsidiary Guarantors, as the case may be, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the
Securities or the Subsidiary Guarantees endorsed thereon, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Securities and perform its obligations hereunder, and that the statements
made by it or to be made by it in a Statement of Eligibility on Form T-1 supplied to the Company are true and accurate. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities or
the proceeds thereof. 
 Section 6.05 May Hold Securities. The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or
any other agent of the Company or any Subsidiary Guarantor, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 6.08 and 6.13, may otherwise deal with the Company and any Subsidiary
Guarantor with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 
 Section 6.06 Money Held in Trust. Money held by the Trustee in trust hereunder (including amounts held by the Trustee as Paying Agent) need not be segregated from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as otherwise agreed with the Company or any Subsidiary Guarantor, as the case may be. 
 Section 6.07 Compensation and Reimbursement. The Company and each Subsidiary Guarantor jointly and severally agree: 
 (1) to pay to the Trustee from time to time reasonable compensation as negotiated between the Company and the Trustee for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust); 
 (2) except as otherwise expressly provided herein, to reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its
agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and 
 (3)
to indemnify the Trustee for, and to hold it harmless against, any loss, liability, damage, claim or expense, including taxes (other than taxes based upon or determined or measured by the income of the Trustee), incurred without negligence or bad
faith on its part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder. 
 The Trustee shall have a lien prior to the Securities as to all property and funds held by it
hereunder for any amount owing it or any predecessor Trustee pursuant to this Section 6.07, except with respect to funds held in trust for the benefit of the Holders of particular Securities. 
 When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 5.01(5) or Section 5.01(6), the expenses
(including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable federal or state bankruptcy, insolvency or other similar law. 

 

 38 








 The provisions of this Section shall survive the termination of this Indenture. 
 Section 6.08 Conflicting Interests. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee
shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by such Act, the Trustee shall not be deemed to have a
conflicting interest by virtue of being a trustee under this Indenture with respect to Securities of more than one series. 
 Section 6.09 Corporate
Trustee Required; Eligibility. There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be Trustee hereunder for Securities of one or more other series. Each Trustee shall be
a Person that is eligible pursuant to the Trust Indenture Act to act as such, and has a combined capital and surplus of at least $100,000,000. If any such Person publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of this Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. Neither the Company nor any Person directly or indirectly controlling, controlled by, or under common control with the Company may serve as Trustee. If at any time the Trustee
with respect to the Securities of any series shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 
 Section 6.10 Resignation and Removal; Appointment of Successor. No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant
to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 6.11. 
 The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall
not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of such series. 
 The Trustee may be removed at any time with respect to the Securities of any series by Act of the
Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered
to the Trustee within 30 days after the giving of such notice of removal, the Trustee being removed may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series. 
 If at any time: 
 (1) the Trustee shall fail to comply with Section 6.08 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security of such series of Securities for at least six months, or

 (2) the Trustee shall cease to be eligible under Section 6.09 and shall fail to resign after written request therefor by the
Company or by any such Holder of a Security who has been a bona fide Holder of a Security of such series of Securities for at least six months; or 
 (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee
or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (B) subject to
Section 5.14, any Holder who has been a bona fide Holder of a Security of such series of Securities for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees. 
  

 39 








 If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of
Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that
any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the
applicable requirements of Section 6.11. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, upon its acceptance of such appointment in accordance with the
applicable requirements of Section 6.11, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company with respect to such Securities. If no successor
Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 6.11, any Holder who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
 The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor
Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 1.06. Each notice shall include the name of the successor Trustee with respect to the Securities of such series
and the address of its Corporate Trust Office. 
 Section 6.11 Acceptance of Appointment by Successor. In case of the appointment hereunder of a
successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company, the Subsidiary Guarantors and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee
and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. 
 In case of the
appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the Subsidiary Guarantors, the retiring Trustee and each successor Trustee with respect to the Securities of one or more
series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is
not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those
series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust 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; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall
become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities
of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates. 
  


 40 








 Upon request of any such successor Trustee, the Company and the Subsidiary Guarantors shall execute any and all
instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be. 
 No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

 Section 6.12 Merger, Conversion, Consolidation or Succession to Business. Any Person into which the Trustee may be merged or converted or
with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Person succeeding to all or substantially all the corporate trust business of the Trustee, shall be
the successor of the Trustee hereunder, provided such Person shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. As soon as
practicable, the successor Trustee shall give notice of its succession to the Company and the Holders of the Securities then Outstanding in the manner provided in Section 1.06. In case any Securities shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion or consolidation or otherwise as permitted hereunder to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities. 
 Section 6.13 Preferential Collection of Claims Against Company and
Subsidiary Guarantors. If and when the Trustee shall be or become a creditor of the Company, any Subsidiary Guarantor or any other obligor upon the Securities, the Trustee shall be subject to the provisions of the Trust Indenture Act regarding
the collection of claims against the Company, such Subsidiary Guarantor or any such other obligor. 
 Section 6.14 Appointment of Authenticating
Agent. The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of and subject to the direction of the Trustee to authenticate Securities of such series
issued upon original issue and upon exchange, registration of transfer, conversion or partial redemption thereof or pursuant to Section 3.06, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid
and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such
reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a Person organized and doing business under the laws of the United States of America, any state thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $100,000,000 and subject to supervision or examination by Federal or state authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in
this Section. 
 Any Person into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any Person resulting
from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any Person succeeding to all or substantially all the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be
an Authenticating Agent, provided such Person shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. 
 An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency
of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment in the manner provided in Section 1.06 to
all Holders of 

  

 41 








 
Securities of the series with respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of
this Section. 
 The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this
Section 6.14. 
 If an appointment with respect to one or more series of Securities is made pursuant to this Section, the Securities of such
series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternate certificate of authentication in the following form: 
  

									
		 		 	Form of Authenticating Agent’s Certificate of Authentication
					
		 		 		 	Dated:	 	 
					
		 		 		 		 	
		 	 This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

 The rights of Holders to communicate with other Holders with respect to their rights under this Indenture or under the Securities, and the corresponding rights and privileges of the Trustee, shall be as provided by the Trust Indenture Act.

 Every Holder of Securities, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company, the Subsidiary

information, documents or reports required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the Trustee within 15 days after the same is so required to be filed with the Commission
(unless the Company files such documents with the Commission via EDGAR, in which case the Company is not required to transmit such information, documents or reports to the Trustee or the holders of the Notes). If the Company has designated any of
its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by this Section 7.04 shall include a reasonably detailed presentation, either on the face of the financial statements or in the
footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial
condition and results of operations of the Unrestricted Subsidiaries of the Company. 
 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

prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain 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 Corporate Trust Office of the Trustee, and the Company and each Subsidiary Guarantor hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands. 
 The Company may also from time to time designate one or more other offices or agencies where the
Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of
its obligation to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the
location of any such other office or agency. 
 Section 10.03 Money for Securities Payments to Be Held in Trust. If the Company or any
Subsidiary Guarantor shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of or any premium or interest on any of the Securities of that series, segregate and
hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will
promptly notify the Trustee of its action or failure so to act. Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, prior to 11:00 A.M., New York City time, on each due date of the principal of or any
premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its action or failure so to act. The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree
with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the
Company, the Subsidiary Guarantors, if applicable, or any other obligor upon the Securities of that series in the making of any payment in respect of the Securities of that series, upon the written request of the Trustee, forthwith pay to the
Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series. The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. Any money deposited with the Trustee or any Paying Agent, or then held by the
Company, in trust for the payment of the principal of or any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on
Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, shall at
the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The City of New York, New York, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company. 
  

 48 








 Section 10.04 Statement by Officers as to Default. The Company and the Subsidiary Guarantors will deliver to
the Trustee, within 90 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate, stating whether or not to the best knowledge of the signers thereof the Company or any Subsidiary Guarantor, as
the case may be, is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company or any
Subsidiary Guarantor shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. 
 The
Company and each Subsidiary Guarantor shall deliver to the Trustee, as soon as possible and in any event within five days after the Company or such Subsidiary Guarantor becomes aware or should reasonably become aware of the occurrence of an Event of
Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officers’ Certificate setting forth the details of such Event of Default or default, and the action which the Company or such
Subsidiary Guarantor proposes to take with respect thereto. 
 Section 10.05 Existence. Subject to Article 8, the Company will do or cause to be
done all things necessary to preserve and keep in full force and effect the existence, rights (charter and statutory) and franchises of the Company; provided, however, that the Company shall not be required to preserve any such right or franchise if
the Board of Directors of the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders.

 Section 10.06 Waiver of Certain Covenants. Except as otherwise specified as contemplated by Section 3.01 for Securities of such series,
the Company may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any of Sections 10.05 or in any covenant provided pursuant to Section 3.01(21),
9.01(2) or 9.01(7) for the benefit of the Holders of such series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. 
 ARTICLE 11 
 REDEMPTION OF SECURITIES 
 Section 11.01 Applicability of Article. Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with
their terms and (except as otherwise specified as contemplated by Section 3.01 for such Securities) in accordance with this Article; provided, however, that is any provision of any such form of Security shall conflict with any provision of this
Article, the provision of such form of Security shall govern. 
 Section 11.02 Election to Redeem; Notice to Trustee. The election of the
Company to redeem any Securities shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 3.01 for such Securities. In case of any redemption at the election of the Company of less than all the
Securities of any series (including any such redemption affecting only a single Security), the Company shall, at least five Business Days prior to giving notice of such redemption (unless a shorter notice shall be satisfactory to the Trustee),
notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities prior to the expiration of
any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction. 
  

 49 








 Section 11.03 Selection by Trustee of Securities to Be Redeemed. If less than all the Securities of any
series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed or unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected by the Trustee,
from the Outstanding Securities of such series not previously called for redemption, (i) in compliance with the requirements of the principal national securities exchange on which such Securities are listed, if such Securities are listed on any
national securities exchange, and (ii) if such Securities are not so listed, on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of a portion
of the principal amount of any Security of such series, provided that the unredeemed portion of the principal amount of any Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such
Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected by the Trustee, from the
Outstanding Securities of such series and specified tenor not previously called for redemption in accordance with the preceding sentence. 
 The
Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. 
 The provisions of the two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether such Security is to be
redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for
such Security. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of
the principal amount of such Securities which has been or is to be redeemed. If any Security selected for partial redemption is surrendered for conversion after such selection, the unconverted portion of such Security shall be deemed (so far as may
be) to be the portion selected for redemption. Upon any redemption of less than all the Securities of a series, for purposes of selection for redemption the Company and the Trustee may treat as Outstanding any Securities surrendered for
conversion during the period of 15 days next preceding the mailing of a notice of redemption, and need not treat as Outstanding any Security authenticated and delivered during such period in exchange for the unconverted portion of any Security
converted in part during such period. 
 Section 11.04 Notice of Redemption. Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register; provided, however, notice of redemption may be given more than 60
days prior to the Redemption Date if the notice is issued in connection with a satisfaction and discharge pursuant to Article 4. 
 All notices of
redemption shall identify the Securities to be redeemed (including CUSIP number(s)) and shall state: 
 (1) the Redemption Date,

 (2) the Redemption Price, if then determinable and otherwise the method of its determination, 
 (3) if less than all the Outstanding Securities of any series consisting of more than a single Security are to be redeemed, the identification (and,
in the case of partial redemption of any such Securities, the principal amounts) of the particular Securities to be redeemed and, if less than all the Outstanding Securities of any series consisting of a single Security are to be redeemed, the
principal amount of the particular Security to be redeemed, 
 (4) that on the Redemption Date the Redemption Price will become due and
payable upon each such Security to be redeemed and, if applicable, that interest or original issue discount thereon will cease to accrue or accrete on and after said date, 
  


 50 








 (5) the place or places where each such Security is to be surrendered for payment of the Redemption
Price, 
 (6) that the redemption is for a sinking fund, if such is the case, and 
 (7) if applicable, the conversion price then in effect and the date on which the right to convert such Securities to be redeemed will expire.

 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request,
the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense, which notice in either event shall be irrevocable; provided, however, that, in the case of such a notice to be given by the Trustee, the
Company shall have delivered to the Trustee at least 35 days (unless a shorter period is acceptable to the Trustee) prior to the proposed redemption date 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. If any Security called for redemption is converted pursuant hereto, any money deposited with the Trustee or any Paying Agent or so segregated and held in trust
for the redemption of such Security shall be paid to the Company upon delivery of a Company Request to the Trustee or such Paying Agent, or, if then held by the Company, shall be discharged from such trust. 
 Section 11.05 Deposit of Redemption Price. Prior to 11:00 A.M., New York City time, on any Redemption Date, the Company shall deposit with the Trustee or
with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.03) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an
Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date. 
 Section 11.06 Securities Payable on
Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the
Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that, unless otherwise specified as contemplated by Section 3.01, installments of interest whose Stated Maturity is on or prior to the
Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.07.

 If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid,
bear interest from the Redemption Date at the rate prescribed therefor in the Security. 
 Section 11.07 Securities Redeemed in Part. Any
Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, if applicable the Subsidiary Guarantors shall execute the Subsidiary Guarantee endorsed thereon, and the Trustee shall
authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, and having the same terms and conditions
and in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

 ARTICLE 12 
 SINKING FUNDS 
 Section 12.01 Applicability of Article. The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as contemplated by Section 3.01 for such Securities. The minimum amount of any sinking fund payment provided for by the terms of any Securities is herein referred to
as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of such Securities is herein referred to as an “optional sinking fund payment.” If provided for by the terms of any
Securities, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 12.02. Each sinking fund payment shall be applied to the redemption of Securities as provided for by the terms of such Securities.

 Section 12.02 Satisfaction of Sinking Fund Payments with Securities. The Company (1) may deliver Outstanding Securities of a series
(other than any previously called for redemption) and (2) may apply as a credit Securities of a series which have been (x) converted or (y) redeemed either at the election of the Company pursuant to the terms of such Securities or
through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to any Securities of such series required to be
made pursuant to the terms of such Securities as and to the extent provided for by the terms of such Securities; provided, however, that the Securities to be so credited have not been previously so credited. The Securities to be so credited shall be
received and credited for such purpose by the Trustee at the Redemption Price, as specified in the Securities so to be redeemed, for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly. 
 Section 12.03 Redemption of Securities for Sinking Fund. Not less than 35 days prior to each sinking fund payment date for any
Securities, the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for such Securities pursuant to the terms of such Securities, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities pursuant to Section 12.02 and will also deliver to the Trustee any Securities to be so delivered. Not less than 32
days prior to each such sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 11.03 and cause notice of the redemption thereof to be given in the
name of and at the expense of the Company in the manner provided in Section 11.04. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 11.06 and 11.07.

 ARTICLE 13 
 SUBSIDIARY GUARANTEES

 Section 13.01 Applicability of Article. Unless the Company elects to issue any series of Securities without the benefit of the Subsidiary
Guarantees, which election shall be evidenced in or pursuant to the Board Resolution or supplemental indenture establishing such series of Securities pursuant to Section 3.01, the provisions of this Article shall be applicable to each series of
Securities except as otherwise specified in or pursuant to the Board Resolution or supplemental indenture establishing such series pursuant to Section 3.01. 
 Section 13.02 Subsidiary Guarantees. Subject to Section 13.01, each Subsidiary Guarantor hereby, jointly and severally, fully and unconditionally guarantees to each Holder of a Security authenticated and delivered
by the Trustee, the due and prompt payment of the principal of (and premium, if any) and interest on such Security when and as the same shall become due and payable, whether at the Stated Maturity, by acceleration, call for redemption or otherwise,
in accordance with the terms of such Security and of this Indenture, and each Subsidiary Guarantor similarly guarantees to the Trustee the payment of all amounts owing to the Trustee in accordance with the terms of this Indenture applicable to
series of Securities guaranteed by such Subsidiary Guarantor. In case of the failure of the Company promptly to make any such payment, each Subsidiary Guarantor hereby, jointly and severally, agrees to cause such payment to be made promptly when and
as the same shall become due and payable, whether at the Stated Maturity or by acceleration, call for redemption or otherwise, and as if such payment were made by the Company. 
  

 52 








 Each of the Subsidiary Guarantors hereby jointly and severally agrees that its obligations hereunder shall be
absolute, unconditional, irrespective of, and shall be unaffected by, the validity, regularity or enforceability of such Security or this Indenture, the absence of any action to enforce the same or any release, amendment, waiver or indulgence
granted to the Company or any guarantor or any consent to departure from any requirement of any other guarantee of all or any of the Securities of such series or any other circumstances which might otherwise constitute a legal or equitable discharge
or defense of a surety or guarantor; provided, however, that, notwithstanding the foregoing, no such release, amendment, waiver or indulgence shall, without the consent of such Subsidiary Guarantor, increase the principal amount of such Security, or
increase the interest rate thereon, or alter the Stated Maturity thereof. Each of the Subsidiary Guarantors hereby waives the benefits of diligence, presentment, demand for payment, any requirement that the Trustee or any of the Holders protect,
secure, perfect or insure any security interest in or other lien on any property subject thereto or exhaust any right or take any action against the Company or any other Person or any collateral, filing of claims with a court in the event of
insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest or notice with respect to such Security or the indebtedness evidenced thereby and all demands whatsoever, and covenants that this
Subsidiary Guarantee will not be discharged in respect of such Security except by complete performance of the obligations contained in such Security and in such Subsidiary Guarantee. Each Subsidiary Guarantor agrees that if, after the occurrence and
during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Securities of a series, to collect interest on the Securities
of a series, or to enforce or exercise any other right or remedy with respect to the Securities of a series, such Subsidiary Guarantor agrees to pay to the Trustee for the account of the Holders, upon demand therefore, the amount that would
otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders. 
 Each
Subsidiary Guarantor shall be subrogated to all rights of the Holders of the Securities upon which its Subsidiary Guarantee is endorsed against the Company in respect of any amounts paid by such Subsidiary Guarantor on account of such Security
pursuant to the provisions of its Subsidiary Guarantee or this Indenture; provided, however, that no Subsidiary Guarantor shall be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation until the
principal of (and premium, if any) and interest on all Securities of the relevant series issued hereunder shall have been paid in full. 
 Each
Subsidiary Guarantor that makes or is required to make any payment in respect of its Subsidiary Guarantee shall be entitled to seek contribution from the other Subsidiary Guarantors to the extent permitted by applicable law; provided, however, that
no Subsidiary Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of contribution until the principal of (and premium, if any) and interest on all Securities of the relevant series issued
hereunder shall have been paid in full. 
 Each Subsidiary Guarantee shall remain in full force and effect and continue to be effective should any
petition be filed by or against the Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any part of the
Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Securities of a series, is, pursuant to applicable law, rescinded
or reduced in amount, or must otherwise be restored or returned by any Holder of the Securities, whether as a “voidable preference,” “fraudulent transfer,” or otherwise, all as though such payment or performance had not been
made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Securities shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded,
reduced, restored or returned. 
 Section 13.03 Execution and Delivery of Subsidiary Guarantees. The Subsidiary Guarantees to be endorsed on the
Securities shall include the terms of the Subsidiary Guarantee set forth in Section 13.02 and any other terms that may be set forth in the form established pursuant to Section 2.04. Subject to Section 13.01, each of the Subsidiary
Guarantors hereby agrees to execute its Subsidiary Guarantee, in a form established pursuant to Section 2.04, to be endorsed on each Security authenticated and delivered by the Trustee. 
 The Subsidiary Guarantee shall be executed on behalf of each respective Subsidiary Guarantor by any one of such Subsidiary Guarantor’s Chief Executive
Officer, President, Chief Financial Officer or Chief Operating Officer. The signature of any or all of these persons on the Subsidiary Guarantee may be manual or facsimile. A 

  

 53 








 
Subsidiary Guarantee bearing the manual or facsimile signature of individuals who were at any time the proper officers of a Subsidiary Guarantor shall bind such
Subsidiary Guarantor, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of the Security on which such Subsidiary Guarantee is endorsed or did not hold such offices at the
date of such Subsidiary Guarantee. 
 The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due
delivery of the Subsidiary Guarantee endorsed thereon on behalf of the Subsidiary Guarantors and shall bind each Subsidiary Guarantor notwithstanding the fact that Subsidiary Guarantee does not bear the signature of such Subsidiary Guarantor. Each
of the Subsidiary Guarantors hereby jointly and severally agrees that, except in circumstances contemplated in Section 13.01 wherein the Company elects to issue a series of Securities without the benefit of Subsidiary Guarantees, its Subsidiary
Guarantee set forth in Section 13.02 and in the form of Subsidiary Guarantee established pursuant to Section 2.04 shall remain in full force and effect notwithstanding any failure to endorse a Subsidiary Guarantee on any Security that was
intended to include the benefit of Subsidiary Guarantees. 
 Section 13.04 Release of Subsidiary Guarantors. Unless otherwise specified pursuant
to Section 3.01 with respect to a series of Securities, each Subsidiary Guarantee will remain in effect with respect to the respective Subsidiary Guarantor until the entire principal of, premium, if any, and interest on the Securities to which
such Subsidiary Guarantee relates shall have been paid in full or otherwise satisfied and discharged in accordance with the provisions of such Securities and this Indenture and all amounts owing to the Trustee hereunder have been paid; provided,
however, that if (i) such Subsidiary Guarantor ceases to be a Subsidiary in compliance with the applicable provisions of this Indenture, (ii) either Defeasance or Covenant Defeasance occurs with respect to such Securities pursuant to
Article 15, (iii) all or substantially all of the assets of such Subsidiary Guarantor or all of the Capital Stock of such Subsidiary Guarantor is sold (including by sale, merger, consolidation or otherwise) by the Company or any Subsidiary
in a transaction complying with the requirements of this Indenture, or (iv) the Company designates a Subsidiary Guarantor to be an Unrestricted Subsidiary in accordance with the definition of “Unrestricted Subsidiary” in
Section 1.01 then, in each case of (i), (ii), (iii) or (iv) upon delivery by the Company of an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent herein provided for relating to the release of
such Subsidiary Guarantor from its obligations under its Subsidiary Guarantee and this Article 13 have been complied with, such Subsidiary Guarantor shall be released and discharged of its obligations under its Subsidiary Guarantee and under this
Indenture without any action on the part of the Trustee or any Holder, and the Trustee shall execute any documents reasonably required in order to acknowledge the release of such Subsidiary Guarantor from its obligations under its Subsidiary
Guarantee endorsed on the Securities of such series and under this Indenture. 
 Section 13.05 Additional Subsidiary Guarantors. Unless
otherwise specified pursuant to Section 3.01 with respect to a series of Securities, if the Company or any of its Restricted Subsidiaries shall, after the effective date of this Indenture, acquire or create another Significant Subsidiary or if
any other Restricted Subsidiary shall become a Significant Subsidiary, then such Significant Subsidiary shall become a Subsidiary Guarantor as follows; provided however, that this requirement shall not apply to a Significant Subsidiary that is also
a Foreign Subsidiary. The Company shall cause any such Significant Subsidiary to execute and deliver to the Trustee (a) a supplemental indenture, in form and substance satisfactory to the Trustee, which subjects such Person to the provisions
(including the representations and warranties) of this Indenture as a Subsidiary Guarantor and (b) an Opinion of Counsel and an Officers’ Certificate to the effect that such supplemental indenture has been duly authorized and executed by
such Person and such supplemental indenture and such Person’s obligations under its Subsidiary Guarantee and this Indenture constitute the legal, valid, binding and enforceable obligations of such Person (subject to such customary exceptions
concerning creditors’ rights and equitable principles as may be acceptable to the Trustee in its discretion). 
 Section 13.06 Limitation on
Liability. Any term or provision of this Indenture to the contrary notwithstanding, the maximum amount of the Subsidiary Guarantee of any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed by such Subsidiary
Guarantor without rendering such Subsidiary Guarantee voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

 [INTENTIONALLY OMITTED] 
 ARTICLE 15 
 DEFEASANCE AND COVENANT DEFEASANCE 
 Section 15.01 Company’s Option to Effect Defeasance or Covenant Defeasance. The
Company may elect, at its option at any time, to have Section 15.02 or Section 15.03 applied to any Securities or any series of Securities, as the case may be, designated pursuant to Section 3.01 as being defeasible pursuant to such
Section 15.02 or 15.03, in accordance with any applicable requirements provided pursuant to Section 3.01 and upon compliance with the applicable conditions set forth below in this Article. Any such election shall be evidenced in or
pursuant to a Board Resolution or in another manner specified as contemplated by Section 3.01 for such Securities. 
 Section 15.02 Defeasance
and Discharge. Upon the Company’s exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, the Company shall be deemed to have been discharged from its obligations,
and each Subsidiary Guarantor shall be deemed to have been discharged from its obligations with respect to its Subsidiary Guarantees of such Securities, as provided in this Section on and after the date the conditions set forth in
Section 15.04 are satisfied (herein called “Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Securities and to have
satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following
which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of such Securities to receive, solely from the trust fund described in Section 15.04 and as more fully set forth in such Section, payments in
respect of the principal of and any premium and interest on such Securities when payments are due, or, if applicable, to convert such Securities in accordance with their terms, (2) the Company’s and each Subsidiary Guarantor’s
obligations with respect to such Securities under Sections 3.04, 3.05, 3.06, 10.02 and 10.03, and, if applicable, their obligations with respect to the conversion of such Securities, (3) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and (4) this Article. Subject to compliance with this Article, the Company may exercise its option (if any) to have this Section applied to any Securities notwithstanding the prior exercise of its option (if any) to have
Section 15.03 applied to such Securities. 
 Section 15.03 Covenant Defeasance. Upon the Company’s exercise of its option (if any) to
have this Section applied to any Securities or any series of Securities, as the case may be, (1) the Company shall be released from its obligations under Section 8.01(3), Sections 10.05, and any covenants provided pursuant to
Section 3.01(21), 9.01(2) or 9.01(7) for the benefit of the Holders of such Securities, and (2) the occurrence of any event specified in Sections 5.01(4) (with respect to any of Section 8.01(3), and any such covenants provided
pursuant to Section 3.01(21), 9.01(2) or 9.01(7)), 5.01(7) and 5.01(8) shall be deemed not to be or result in an Event of Default and (3) the provisions of Article 13 shall cease to be effective, in each case with respect to such
Securities and Subsidiary Guarantees as provided in this Section on and after the date the applicable conditions set forth in Section 15.04 are satisfied (herein called “Covenant Defeasance”). For this purpose, such Covenant
Defeasance means that, with respect to such Securities, the Company and the Subsidiary Guarantors, as applicable, may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified
Section (to the extent so specified in the case of Section 5.01(4)) or Article 13 whether directly or indirectly by reason of any reference elsewhere herein to any such Section or Article or by reason of any reference in any such
Section or Article to any other provision herein or in any other document, and such omission to comply shall not constitute an Event of Default under this Indenture or any such supplemental indenture with respect to Outstanding Securities of
such series, and but the remainder of this Indenture and such Securities shall be unaffected thereby. 
 Section 15.04 Conditions to Defeasance or
Covenant Defeasance. The following shall be the conditions to the application of Section 15.02 or Section 15.03 to any Securities or any series of Securities, as the case may be: 
 (1) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee which satisfies the requirements
contemplated by Section 6.09 and agrees to comply 

  

 55 








 
with the provisions of this Article applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for,
and dedicated solely to, the benefit of the Holders of such Securities, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their
terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, in each case sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed
in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee) to pay and discharge, the principal of and any premium and interest on such
Securities on the respective Stated Maturities, in accordance with the terms of this Indenture and such Securities. As used herein, “U.S. Government Obligation” means (x) any security which is (i) a direct obligation of the
United States of America for the payment of which the full faith and credit of the United States of America is pledged or (ii) an obligation of a Person controlled or supervised by and acting as an agency or instrumentality of the United States
of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case (i) or (ii), is not callable or redeemable at the option of the issuer thereof, and
(y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S. Government Obligation which is specified in clause (x) above and held by such bank for the
account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on any U.S. Government Obligation which is so specified and held, provided that (except as required by law) such custodian is not
authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principal or interest evidenced by
such depositary receipt. 
 (2) In the event of an election to have Section 15.02 apply to any Securities or any series of
Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the
date of this instrument, there has been a change in the applicable Federal income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Securities will not recognize
gain or loss for Federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times
as would be the case if such deposit, Defeasance and discharge were not to occur. 
 (3) In the event of an election to have
Section 15.03 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for
Federal income tax purposes as a result of the deposit and Covenant Defeasance to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case
if such deposit and Covenant Defeasance were not to occur. 
 (4) The Company shall have delivered to the Trustee an Officers’
Certificate to the effect that neither such Securities nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit. 
 (5) No event which is, or after notice or lapse of time or both would become, an Event of Default with respect to such Securities or any other
Securities shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in Sections 5.01(5) and (6), at any time on or prior to the 121st day after the date of such deposit (it being understood that
this condition shall not be deemed satisfied until after such 121st day). 
 (6) Such Defeasance or Covenant Defeasance shall not cause
the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act). 
  

 56 








 (7) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or
constitute a default under, any other agreement or instrument to which the Company or any Subsidiary is a party or by which it is bound. 
 (8) The Company shall have delivered to the Trustee an Opinion of Counsel to the effect that such deposit shall not cause either the Trustee or the trust so created to be subject to the Investment Company Act of 1940. 
 (9) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent with respect to such Defeasance or Covenant Defeasance have been complied with. 
 Section 15.05 Deposited Money and U.S. Government
Obligations to Be Held in Trust; Miscellaneous Provisions. Subject to the provisions of the last paragraph of Section 10.03, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee or other
qualifying trustee (solely for purposes of this Section and Section 15.06, the Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to Section 15.04 in respect of any Securities shall be
held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee
may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other funds except to the extent required by
law. 
 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government
Obligations deposited pursuant to Section 15.04 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 Outstanding Securities. 
 Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S.
Government Obligations held by it as provided in Section 15.04 with respect to any Securities which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities. 
 Section 15.06 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money or U.S. Government Obligations, as the case may be, in
accordance with this Article with respect to any Securities by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and
such Securities from which the Company has been discharged or released pursuant to Section 15.02 or 15.03 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such
time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 15.05 with respect to such Securities in accordance with this Article; provided, however, that if the Company makes any payment of principal
of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust.

 ARTICLE 16 
 SUBORDINATION 
 Section 16.01 Securities Subordinated to Senior Debt. Except as otherwise specified or contemplated by Section 3.01 or the other provisions of this
Indenture, the Company covenants and agrees, and each Holder of a Security, by his acceptance thereof, likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article 16, the payment of the principal of and
premium and other amounts, if any, and interest on each and all of the Securities is hereby expressly made subordinate and subject in right of payment to the prior payment in full of all Senior Debt. The terms of this Article 16 may be modified or
amended for any series of Securities as contemplated by Section 3.01. 
  

 57 








 Section 16.02 Payment Over of Proceeds upon Dissolution, Etc. In the event of (a) any insolvency or
bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to the Company or to its creditors or to its assets, or (b) any liquidation, dissolution or
other winding up of the Company, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or any other marshalling of assets and liabilities of the Company, then
and in any such event specified in (a), (b) or (c) above (each such event, if any, a “Proceeding”) the holders of Senior Debt shall be entitled to receive payment in full of all amounts due or to become due on or in respect of
all Senior Debt, or provision shall be made for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Debt, before the holders of the Securities are entitled to receive any payment or distribution of
any kind or character, whether in cash, property or securities, on account of principal of or premium and other amounts, if any, or interest on the Securities or on account of any purchase or other acquisition of Securities by the Company, or any
Subsidiary of the Company (all such payments, distributions, purchases and acquisitions herein referred to, individually and collectively, as a “Securities Payment”), and to that end the holders of all Senior Debt shall be entitled to
receive, for application to the payment thereof, any Securities Payment which may be payable or deliverable in respect of the Securities in any such Proceeding. 
 In the event that, notwithstanding the foregoing provisions of this Section, the Trustee or the holder of any Security shall have received any Securities Payment before all Senior Debt is paid in full or payment thereof
provided for in cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Debt, and if such fact shall, at or prior to the time of such Securities Payment, have been made known to the Trustee or, as the case may be,
such holder, then and in such event such Securities Payment shall be paid over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other Person making payment or distribution of assets of
the Company for application to the payment of all Senior Debt remaining unpaid, to the extent necessary to pay all Senior Debt in full, after giving effect to any concurrent payment or distribution to or for the holders of Senior Debt. 

For purposes of this Article only, the words “any payment or distribution of any kind or character, whether in cash, property or securities” shall not
be deemed to include a payment or distribution of stock or securities of the Company provided for by a plan of reorganization or readjustment authorized by an order or decree of a court of competent jurisdiction in a reorganization proceeding under
any applicable bankruptcy law or of any other corporation provided for by such plan of reorganization or readjustment which stock or securities are subordinated in right of payment to all then outstanding Senior Debt to substantially the same extent
as the Securities are so subordinated as provided in this Article. The consolidation of the Company with, or the merger of the Company into, another Person or the liquidation or dissolution of the Company following the conveyance, transfer, sale or
lease of all or substantially all of its properties and assets to another Person upon the terms and conditions set forth in Article 8 shall not be deemed a Proceeding for the purposes of this Section if the Person formed by such consolidation
or into which the Company is merged or the Person which acquires by conveyance, transfer, sale or lease such properties and assets, as the case may be, shall, as a part of such consolidation, merger, conveyance, transfer, sale or lease, comply with
the conditions set forth in Article 8. 
 Section 16.03 Payment of Senior Debt before Payment of Securities. In the event that any series of
Securities are declared due and payable before their Stated Maturity, then and in such event the holders of the Senior Debt outstanding at the time such series of Securities so becomes due and payable shall be entitled to receive payment in full of
all amounts due or to become due on or in respect of all Senior Debt, or provision shall be made for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders of such Senior Debt, before the holders of the
Securities of such series are entitled to receive any Securities Payment. 
 In the event and during the continuation of any default in the payment of
principal or of premium or other amounts, if any, or interest on any Senior Debt beyond any applicable grace period with respect thereto, or in the event that any event of default with respect to any Senior Debt shall have occurred and be continuing
permitting the holders of such Senior Debt (or a trustee, or other representative on behalf of the holders thereof) to declare such Senior Debt due and payable prior to the date on which it would otherwise have become due and payable, unless and
until such event of default shall have been cured or waived or shall have ceased to exist and any such acceleration shall have been rescinded or annulled, or in the event any judicial proceeding shall be pending with respect to any such default in
payment or event of default, then no Securities Payment shall be made. 
  

 58 








 In the event that, notwithstanding the foregoing, the Company shall make any Securities Payment to the Trustee or
any holder prohibited by the foregoing provisions of this Section, and if such fact shall, at or prior to the time of such Securities Payment, have been made known to the Trustee or, as the case may be, such holder, then and in such event such
Securities Payment shall be paid over and delivered forthwith to the Company. 
 The provisions of this Section shall not apply to any Securities
Payment with respect to which Section 16.02 would be applicable. 
 Section 16.04 Payment Permitted if No Default. Nothing contained in
this Article or elsewhere in this Indenture or in any of the Securities shall prevent (a) the Company, at any time except during the pendency of any Proceeding referred to in Section 16.02 or under the conditions described in
Section 16.03, from making Securities Payments, or (b) the application by the Trustee of any money deposited with it hereunder to Securities Payments or the retention of such Securities Payment by the holders, if at the time of such
application by the Trustee, it did not have actual knowledge that such Securities Payment would have been prohibited by the provisions of this Article. 
 Section 16.05 Subrogation to Rights of Holders of Senior Debt. Subject to the payment in full of all amounts due or to become due on or in respect of Senior Debt, or the provision for such payment in cash or cash equivalents or
otherwise in a manner satisfactory to the holders of Senior Debt, the holders of the Securities shall be subrogated to the rights of the holders of such Senior Debt to receive payments and distributions of cash, property and securities applicable to
the Senior Debt until the principal of and premium and other amounts, if any, and interest on the Securities shall be paid in full. For purposes of such subrogation, no payments or distributions to the holders of the Senior Debt of any cash,
property or securities to which the holders of the Securities or the Trustee would be entitled except for the provisions of this Article, and no payments over pursuant to the provisions of this Article to the holders of Senior Debt by holders of the
Securities or the Trustee, shall, as among the Company, its creditors other than holders of Senior Debt and the holders of the Securities, be deemed to be a payment or distribution by the Company to or on account of the Senior Debt. 
 Section 16.06 Provisions Solely to Define Relative Rights. The provisions of this Article are and are intended solely for the purpose of defining the
relative rights of the holders of the Securities on the one hand and the holders of Senior Debt on the other hand. Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall (a) impair, as
among the Company, its creditors other than holders of Senior Debt and the holders of the Securities, the obligation of the Company, which is absolute and unconditional (and which, subject to the rights under this Article of the holders of Senior
Debt, is intended to rank equally with all other general obligations of the Company), to pay to the holders of the Securities the principal of and premium and other amounts, if any, and interest on the Securities as and when the same shall become
due and payable in accordance with their terms; or (b) affect the relative rights against the Company of the holders of the Securities and creditors of the Company other than the holders of Senior Debt; or (c) prevent the Trustee or the
holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article of the holders of Senior Debt to receive cash, property and securities
otherwise payable or deliverable to the Trustee or such holder. 
 Section 16.07 Trustee to Effectuate Subordination. Each holder of a Security
by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee his attorney-in-fact for any and all
such purposes. 
 Section 16.08 No Waiver of Subordination Provisions. No right of any present or future holder of any Senior Debt to enforce
subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the
Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. Without in any way limiting the generality of the foregoing paragraph, the holders of
Senior Debt may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders of the Securities, without incurring responsibility to the holders of the Securities and without impairing or releasing the
subordination provided in this Article or the obligations hereunder of the holders of the Securities to the holders of Senior Debt, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of
payment of, or renew or alter, Senior Debt, or otherwise amend or supplement in any manner Senior Debt or any instrument evidencing the same or any 

  

 59 








 
agreement under which Senior Debt is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior
Debt; (iii) release any Person liable in any manner for the collection of Senior Debt; and (iv) exercise or refrain from exercising any rights against the Company and any other Person. 
 Section 16.09 Notice to Trustee. The Company shall give prompt written notice to the Trustee of any fact known to the Company which would prohibit the
making of any payment to or by the Trustee in respect of the Securities. Notwithstanding the provisions of this Article or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which
would prohibit the making of any payment to or by the Trustee in respect of the Securities, unless and until a Responsible Officer of the Trustee shall have received written notice thereof from the Company or a holder of Senior Debt or from any
trustee therefor or representative thereof; and, prior to the receipt of any such written notice, the Trustee shall be entitled in all respects to assume that no such facts exist; provided, however, that if the Trustee shall not have received the
notice provided for in this Section at least one full Business Day prior to the date upon which by the terms hereof any money may become payable for any purpose (including, without limitation, the payment of the principal of and premium and
other amounts, if any, or interest on any Security), then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money was
received and shall not be affected by any notice to the contrary which may be received by it within one full Business Day prior to such date. 
 Subject to the provisions of Section 6.01, the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Debt (or a trustee therefor or representative thereof)
to establish that such notice has been given by a holder of Senior Debt (or a trustee therefor or representative thereof). In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any
Person as a holder of Senior Debt to participate in any payment or distribution pursuant to this Article, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Debt held by
such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article, and if such evidence is not furnished, the Trustee may defer any
payment to such Person pending judicial determination as to the rights of such Person to receive such payment. 
 Section 16.10 Reliance on Judicial
Order or Certificate of Liquidating Agent. Upon any payment or distribution of assets of the Company referred to in this Article, the Trustee, subject to the provisions of Section 6.01, and the holders of the Securities shall be entitled to
rely upon any order or decree entered by any court of competent jurisdiction in which such Proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent
or other Person making such payment or distribution, delivered to the Trustee or to the holders of Securities, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Debt and
other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article. 
 Section 16.11 Trustee Not Fiduciary for Holders of Senior Debt. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt and
shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to holders of Securities or to the Company or to any other Person cash, property or securities to which any holders of Senior Debt shall be entitled
by virtue of this Article or otherwise. The Trustee shall not be charged with knowledge of the existence of Senior Debt or of any facts that would prohibit any payment hereunder unless a Responsible Officer of the Trustee shall have received notice
to that effect at the address of the Trustee set forth in Section 1.05. With respect to the holders of Senior Debt, the Trustee undertakes to perform or to observe only such of its covenants or obligations as are specifically set forth in this
Article and no implied covenants or obligations with respect to holders of Senior Debt shall be read into this Indenture against the Trustee. 
 Section 16.12 Rights of Trustee as Holder of Senior Debt; Preservation of Trustee’s Rights. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article with respect to any Senior Debt
which may at any time be held by it, to the same extent as any other holder of Senior Debt, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. 
  

 60 








 Nothing in this Article shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 6.07. 
 Section 16.13 Article Applicable to Paying Agents. In case at any time any paying agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article shall in such case (unless the context otherwise requires) be construed as extending to and including such paying agent within its
meaning as fully for all intents and purposes as if such paying agent were named in this Article in addition to or in place of the Trustee; provided, however, that Sections 16.09 and 16.12 shall not apply to the Company or any Affiliate of the
Company if it or such Affiliate acts as Paying Agent. 
 This Indenture may be executed in any number of counterparts, each of which so executed shall
be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument. The exchange of copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution
and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all
purposes. 
 IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed, all as of the day and year first above written.
