indenture or an Officers’ Certificate detailing the adoption of the terms thereof pursuant to the authority granted under a Board Resolution. In the case of Securities of a Series to be issued from time to time, the Board Resolution,
Officers’ Certificate or supplemental indenture may provide for the method by which specified terms (such as interest rate, maturity date, record date or date from which interest shall accrue) are to be determined. Securities may differ between
Series in respect of any matters, provided that all Series of Securities shall be equally and ratably entitled to the benefits of the Indenture [INCLUDE THIS LANGUAGE FOR SUBORDINATED SECURITIES but all Securities issued hereunder shall be
subordinate and junior in right of payment, to the extent and in the manner set forth in Article XII, to all Senior Indebtedness of the Company.]

payable on any interest payment date; 
  
 2.2.6. the place or
places where the principal of and interest, if any, on the Securities of the Series shall be payable, or the method of such payment, if by wire transfer, mail or other means;

thereof, the denominations in which the Securities of the Series shall be issuable; 
  
 2.2.11. the forms of the Securities of the Series in bearer or fully registered form (and, if in fully registered form, whether the Securities will be issuable as Global Securities); 
  
 2.2.12. if other than the principal amount thereof, the portion of the

any Securities of the Series and any change in the right of the Trustee or the requisite Holders of such Securities to declare the principal amount thereof due and payable pursuant to Section 6.2; 
  
 2.2.20. any addition to or change in the covenants set forth in Articles IV
or V which applies to Securities of the Series; 
  
 2.2.21. any

such Series); and 
  

 8 








 2.2.22. any depositories, interest rate calculation agents, exchange rate calculation agents or other
agents with respect to Securities of such Series if other than those appointed herein. 
  
 All Securities of any one Series need not be issued at the same time and may be issued from time to time, consistent with the terms of this Indenture, if so provided by or pursuant to the Board Resolution,
supplemental indenture or Officers’ Certificate referred to above, and the authorized principal amount of any Series may not be increased to provide for issuances of additional Securities of such Series, unless otherwise provided in such Board
Resolution, supplemental indenture or Officers’ Certificate. 
  
 Section 2.3. Execution and Authentication. 
  
 Two
Officers shall sign the Securities for the Company by manual or facsimile signature. 
  
 If an Officer whose signature is on a Security no longer holds that office at the time the Security is authenticated, the Security shall nevertheless be valid. 
  
 A Security shall not be valid until authenticated by the manual signature of
the Trustee or an authenticating agent. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. 
  
 The Trustee shall at any time, and from time to time, authenticate Securities for original issue in the principal amount provided in the Board Resolution,
supplemental indenture hereto or Officers’ Certificate, upon receipt by the Trustee of a Company Order. Such Company Order may authorize authentication and delivery pursuant to oral or electronic instructions from the Company or its duly
authorized agent or agents, which oral instructions shall be promptly confirmed in writing. Each Security shall be dated the date of its authentication unless otherwise provided by a Board Resolution, a supplemental indenture hereto or an
Officers’ Certificate. 
  
 The aggregate principal amount of
Securities of any Series outstanding at any time may not exceed any limit upon the maximum principal amount for such Series set forth in the Board Resolution, supplemental indenture hereto or Officers’ Certificate delivered pursuant to Section
2.2, except as provided in Section 2.8. 
  
 Prior to the issuance
of Securities of any Series, the Trustee shall have received and (subject to Section 7.2) shall be fully protected in relying on: (a) the Board Resolution, supplemental indenture hereto or Officers’ Certificate establishing the form of the
Securities of that Series or of Securities within that Series and the terms of the Securities of that Series or of Securities within that Series, (b) an Officers’ Certificate complying with Section 10.4, and (c) an Opinion of Counsel complying
with Section 10.4. 
  
 The Trustee shall have the right to decline
to authenticate and deliver any Securities of such Series: (a) if the Trustee, being advised by counsel, determines that such action may not lawfully be taken; or (b) if the Trustee in good faith by its board of directors or trustees, executive
committee or a trust committee of directors and/or vice-presidents shall determine that such action would expose the Trustee to personal liability to Holders of any then outstanding Series of Securities. 
  
 The Trustee may appoint an authenticating agent acceptable to the Company to
authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the
same rights as an Agent to deal with the Company or an Affiliate.

 Section 2.4. Registrar and Paying Agent. 
  
 The Company shall maintain, with respect to each Series of Securities, at the place or places specified with respect to such
Series pursuant to Section 2.2, an office or agency where Securities of such Series may be presented or surrendered for payment (“Paying Agent”), where Securities of such Series may be surrendered for registration of transfer or exchange
(“Registrar”) and where notices and demands to or upon the Company in respect of the Securities of such Series and this Indenture may be served (“Service Agent”). The Registrar shall keep a register with respect to each Series of
Securities and to their transfer and exchange. The Company will give prompt written notice to the Trustee of the name and address, and any change in the name or address, of each Registrar, Paying Agent or Service Agent. If at any time the Company
shall fail to maintain any such required Registrar, Paying Agent or Service Agent or shall fail to furnish the Trustee with the name and address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate
Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 
  
 The Company may also from time to time designate one or more co-registrars, additional paying agents or additional service agents 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 obligations to maintain a Registrar, Paying Agent and Service Agent in each place so specified pursuant to
Section 2.2 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 name or address of any such co-registrar, additional paying agent
or additional service agent. The term “Registrar” includes any co-registrar; the term “Paying Agent” includes any additional paying agent; and the term “Service Agent” includes any additional service agent. 

 
 The Company hereby appoints the Trustee the initial Registrar, Paying
Agent and Service Agent for each Series unless another Registrar, Paying Agent or Service Agent, as the case may be, is appointed prior to the time Securities of that Series are first issued. 
  
 Section 2.5. Paying Agent to Hold Money in Trust. 
  
 The Company shall require each Paying Agent other than the Trustee to agree
in writing that the Paying Agent will hold in trust, for the benefit of Securityholders of any Series of Securities, or the Trustee, all money held by the Paying Agent for the payment of principal of or interest on the Series of Securities, and will
notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to
pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall
segregate and hold in a separate trust fund for the benefit of Securityholders of any Series of Securities all money held by it as Paying Agent. 
  
 Section 2.6. Securityholder Lists. 
  
 The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of
Securityholders of each Series of Securities and shall otherwise comply with TIA Section 312(a) . If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least ten days before each interest payment date and at such other
times as the Trustee may request in writing a list, in such form and as of such date as the Trustee may reasonably require, of the names and addresses of Securityholders of each Series of Securities. 
  

 10 








 Section 2.7. Transfer and Exchange. 
  
 Where Securities of a Series are presented to the Registrar or a co-registrar with a request to register a transfer or to
exchange them for an equal principal amount of Securities of the same Series, the Registrar shall register the transfer or make the exchange if its requirements for such transactions are met. To permit registrations of transfers and exchanges, the
Trustee shall authenticate Securities at the Registrar’s request. No service charge shall be made for any registration of transfer or exchange (except as otherwise expressly permitted herein), but the Company may require payment of a sum
sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer tax or similar governmental charge payable upon exchanges pursuant to Sections 2.11, 3.6 or 9.6). 
  
 Neither the Company nor the Registrar shall be required (a) to issue,
register the transfer of, or exchange Securities of any Series for the period beginning at the opening of business fifteen days immediately preceding the mailing of a notice of redemption of Securities of that Series selected for redemption and
ending at the close of business on the day of such mailing, or (b) to register the transfer of or exchange Securities of any Series selected, called or being called for redemption as a whole or the portion being redeemed of any such Securities
selected, called or being called for redemption in part. 
  
 Section 2.8. Mutilated, Destroyed, Lost and Stolen Securities. 
  
 If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same Series and of like tenor and principal amount and bearing a
number not contemporaneously outstanding. 
  
 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, 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 and upon its request the Trustee shall authenticate and make available for delivery, 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, the Company
in its discretion may, instead of issuing a new Security, pay such 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 shall constitute an original additional contractual obligation of the Company, 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.

  
 The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
  

 11 








 Section 2.9. Outstanding Securities. 
  
 The Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by it,
those delivered to it for cancellation, those reductions in the interest on a Global Security effected by the Trustee in accordance with the provisions hereof and those described in this Section as not outstanding. 
  
 If a Security is replaced pursuant to Section 2.8, it ceases to be
outstanding until the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. 
  
 If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds on the Maturity of Securities of a Series money sufficient
to pay such Securities payable on that date, then on and after that date such Securities of the Series cease to be outstanding and interest on them ceases to accrue. 
  
 A Security does not cease to be outstanding because the Company or an Affiliate holds the Security. 
  
 In determining whether the Holders of the requisite principal amount of
outstanding Securities have given any request, demand, authorization, direction, notice, consent or waiver hereunder, the principal amount of a Discount Security that shall be deemed to be outstanding for such purposes shall be the amount of the
principal thereof that would be due and payable as of the date of such determination upon a declaration of acceleration of the Maturity thereof pursuant to Section 6.2. 
  
 Section 2.10. Treasury Securities. 
  

In determining whether the Holders of the required principal amount of Securities of a Series have concurred in any request, demand, authorization,
direction, notice, consent or waiver Securities of a Series owned by the Company or an Affiliate shall be disregarded, except that for the purposes of determining whether the Trustee shall be protected in relying on any such request, demand,
authorization, direction, notice, consent or waiver only Securities of a Series that the Trustee knows are so owned shall be so disregarded. 
  
 Section 2.11. Temporary Securities. 
  
 Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities upon a Company Order.
Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee upon
request shall authenticate definitive Securities of the same Series and date of maturity in exchange for temporary Securities. Until so exchanged, temporary securities shall have the same rights under this Indenture as the definitive Securities.

  
 Section 2.12. Cancellation. 
  
 The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Securities surrendered for transfer, exchange, payment,
replacement or cancellation and shall destroy such canceled Securities (subject to the record retention requirement of the Exchange Act) and deliver a certificate of such destruction to the Company, 

  

 12 








 
unless the Company otherwise directs. The Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for
cancellation. 
  
 Section 2.13. Defaulted Interest. 
  
 If the Company defaults in a payment of interest on a Series of Securities,
it shall pay the defaulted interest, plus, to the extent permitted by law, any interest payable on the defaulted interest, to the persons who are Securityholders of the Series on a subsequent special record date. The Company shall fix the record
date and payment date. At least 30 days before the record date, the Company shall mail to the Trustee and to each Securityholder of the Series a notice that states the record date, the payment date and the amount of interest to be paid. The Company
may pay defaulted interest in any other lawful manner. 
  
 Section
2.14. Global Securities. 
  
 2.14.1. Terms of Securities. A Board
Resolution, a supplemental indenture hereto or an Officers’ Certificate shall establish whether the Securities of a Series shall be issued in whole or in part in the form of one or more Global Securities and the Depository for such Global
Security or Securities. 
  
 2.14.2. Transfer and Exchange.
Notwithstanding any provisions to the contrary contained in Section 2.7 of the Indenture and in addition thereto, any Global Security shall be exchangeable pursuant to Section 2.7 of the Indenture for Securities registered in the names of Holders
other than the Depository for such Security or its nominee only if (i) such Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Security or if at any time such Depository ceases to be a clearing
agency registered under the Exchange Act, and, in either case, the Company fails to appoint a successor Depository within 90 days of such event, (ii) the Company executes and delivers to the Trustee an Officers’ Certificate to the effect that
such Global Security shall be so exchangeable or (iii) an Event of Default with respect to the Securities represented by such Global Security shall have happened and be continuing. Any Global Security that is exchangeable pursuant to the preceding
sentence shall be exchangeable for Securities registered in such names as the Depository shall direct in writing in an aggregate principal amount equal to the principal amount of the Global Security with like tenor and terms. 
  
 Except as provided in this Section 2.14.2, a Global Security may not be
transferred except as a whole by the Depository with respect to such Global Security to a nominee of such Depository, by a nominee of such Depository to such Depository or another nominee of such Depository or by the Depository or any such nominee
to a successor Depository or a nominee of such a successor Depository. 
  
 2.14.3. Legend. Unless otherwise provided pursuant to Section 2.2, any Global Security issued hereunder shall bear a legend in substantially the following form: 
  
 “This Security is a Global Security within the meaning of the Indenture hereinafter referred to and is registered in
the name of the Depository or a nominee of the Depository. This Security is exchangeable for Securities registered in the name of a person other than the Depository or its nominee only in the limited circumstances described in the Indenture, and may
not be transferred except as a whole by the Depository to a nominee of the Depository, by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a
nominee of such a successor Depository.” 
  
 2.14.4. Acts of
Holders. The Depository, as a Holder, may appoint agents and otherwise authorize participants to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a Holder is entitled to give or take under the
Indenture. 
  

 13 








 2.14.5. Payments. Notwithstanding the other provisions of this Indenture, unless otherwise specified as
contemplated by Section 2.2, payment of the principal of, premium, if any, and interest, if any, on any Global Security shall be made to the Holder thereof. 
  
 2.14.6. Consents, Declaration and Directions. Except as provided in Section 2.14.5, the Company, the Trustee and any Agent shall treat a person as the
Holder of such principal amount of outstanding Securities of such Series represented by a Global Security as shall be specified in a written statement of the Depositary with respect to such Global Security, for purposes of obtaining any consents,
declarations, waivers or directions required to be given by the Holders pursuant to this Indenture. 
  
 Section 2.15. CUSIP Numbers. 
  
 The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP”
numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other elements of identification printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. 
  
 ARTICLE III. 
 REDEMPTION 
  
 Section 3.1. Notice to Trustee. 
  
 The Company may, with
respect to any Series of Securities, reserve the right to redeem and pay the Series of Securities or may covenant to redeem and pay the Series of Securities or any part thereof prior to the Stated Maturity thereof at such time and on such terms as
provided for in such Securities. If a Series of Securities is redeemable and the Company wants or is obligated to redeem prior to the Stated Maturity thereof all or part of the Series of Securities pursuant to the terms of such Securities, it shall
notify the Trustee of the redemption date and the principal amount of Series of Securities to be redeemed. The Company shall give the notice at least 45 days before the redemption date (or such shorter notice as may be acceptable to the Trustee).

  
 Section 3.2. Selection of Securities to be Redeemed.

  
 Unless otherwise indicated for a particular Series by a Board
Resolution, a supplemental indenture or an Officers’ Certificate, if less than all the Securities of a Series are to be redeemed, the Trustee shall select the Securities of the Series to be redeemed in any manner that the Trustee deems fair and
appropriate. The Trustee shall make the selection from Securities of the Series outstanding not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities of the Series that have denominations
larger than $1,000. Securities of the Series and portions of them it selects shall be in amounts of $1,000 or whole multiples of $1,000 or, with respect to Securities of any Series issuable in other denominations pursuant to Section 2.2.10, the
minimum principal denomination for each Series and integral multiples thereof. Provisions of this Indenture that apply to Securities of a Series called for redemption also apply to portions of Securities of that Series called for redemption.

  
 Section 3.3. Notice of Redemption. 
  
 Unless otherwise indicated for a particular Series by Board Resolution, a
supplemental indenture hereto or an Officers’ Certificate, at least 30 days but not more than 60 days before a redemption date, the 

  

 14 








 
Company shall mail a notice of redemption by first-class mail to each Holder whose Securities are to be redeemed and if any Bearer Securities are
outstanding, publish on one occasion a notice in an Authorized Newspaper. 
  
 The notice shall identify the Securities of the Series to be redeemed and shall state: 
  

	 	(a)	the redemption date; 

  

	 	(b)	the redemption price; 

  

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

  

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

  

	 	(e)	that interest on Securities of the Series called for redemption ceases to accrue on and after the redemption date; and 

  

	 	(f)	any other information as may be required by the terms of the particular Series or the Securities of a Series being redeemed. 

  
 At the Company’s request, the Trustee shall give the notice of
redemption in the Company’s name and at its expense. 
  
 Section 3.4. Effect of Notice of Redemption. 
  
 Once
notice of redemption is mailed or published as provided in Section 3.3, Securities of a Series called for redemption become due and payable on the redemption date and at the redemption price. A notice of redemption may not be conditional. Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption price plus accrued interest to the redemption date. 
  
 Section 3.5. Deposit of Redemption Price. 
  
 On or before the redemption date, the Company shall deposit with the Paying Agent money sufficient to pay the redemption price of and accrued interest, if
any, on all Securities to be redeemed on that date. 
  
 Section
3.6. Securities Redeemed in Part. 
  
 Upon surrender of a Security
that is redeemed in part, the Trustee shall authenticate for the Holder a new Security of the same Series and the same maturity equal in principal amount to the unredeemed portion of the Security surrendered.

 Section 6.2. Acceleration of Maturity; Rescission and Annulment. 
  

If an Event of Default with respect to Securities of any Series at the time outstanding occurs and is continuing (other than an Event of Default
referred to in Section 6.1(e) or (f) ) then in every such case the Trustee or the Holders of not less than 25% in principal amount of the outstanding Securities of that Series may declare the principal amount (or, if any Securities of that Series
are Discount Securities, such portion of the principal amount as may be specified in the terms of such Securities) of and accrued and unpaid interest, if any, on all of the Securities of that Series to be due and payable immediately, by a 

  

 18 








 
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) and
accrued and unpaid interest, if any, shall become immediately due and payable. If an Event of Default specified in Section 6.1(e) or (f) shall occur, the principal amount (or specified amount) of and accrued and unpaid interest, if any, on all
outstanding Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. 
  

At any time after such a declaration of acceleration with respect to 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 in this Article provided, 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:

or deposited with the Trustee a sum sufficient to pay 
  
 (i) all
overdue interest, if any, on all Securities of that Series,

and counsel; and 
  
 (b) 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 have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 6.13. 
  
 No such rescission shall affect any subsequent Default or impair any right
consequent thereon. 
  
 Section 6.3. Collection of Indebtedness
and Suits for Enforcement by Trustee. 
  
 The Company covenants
that if 
  
 (a) default is made in the payment of any interest on
any Security when such interest becomes due and payable and such default continues for a period of 30 days, or 
  
 (b) default is made in the payment of principal of any Security at the Maturity thereof, or 
  
 (c) default is made in the deposit of any sinking fund payment when and as due by the terms of a Security, then, 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 interest and, to the extent that payment of such interest shall be legally
enforceable, interest on any overdue principal or 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 the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums 

  

 19 








 
so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such
Securities and collect the moneys adjudged or deemed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated. 
  
 If an Event of Default with respect to any 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 6.4. Trustee May File Proofs of Claim. 
  
 In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee
(irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue
principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise, 
  
 (a) to file and prove a claim for the whole amount of principal and interest owing and unpaid in respect of the Securities and to file such other papers
or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in
such judicial proceeding, and 
  
 (b) 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 7.7. 
  
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
  
 Section 6.5. Trustee May Enforce Claims Without Possession of Securities.

  
 All rights of action and claims under this Indenture or the
Securities 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. 
  

 20 








 Section 6.6. Application of Money Collected. 
  
 Any money collected by the Trustee pursuant to this Article shall be applied

and upon surrender thereof if fully paid: 
  
 First: To the
payment of all amounts due the Trustee under Section 7.7; and 
  
 Second: To the payment of the amounts then due and unpaid for principal of and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind,

 Third: To the Company. 
  
 Section 6.7. 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 
  
 (a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that Series; 
  
 (b) 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;

such request; 
  
 (d) the Trustee for 60 days after its receipt of
such notice, request and offer of indemnity has failed to institute any such proceeding; and 
  
 (e) 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 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 such Holders. 
  
 Section 6.8. Unconditional Right of Holders to Receive Principal and
Interest. 
  
 Notwithstanding any other provision in this
Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and interest, if any, on such Security on the Stated Maturity or Stated Maturities expressed in such Security
(or, in the case of redemption, on the redemption date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 
  

 21 








 Section 6.9. 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 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 6.10. Rights and Remedies
Cumulative. 
  
 Except as otherwise provided with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities in Section 2.8, 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 6.11. 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 6.12. 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 
  
 (a) such direction shall not be in conflict with any rule of law or with this Indenture, 
  
 (b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and 
  
 (c) subject to the provisions of Section 7.2, the Trustee shall have the
right to decline to follow any such direction if the Trustee in good faith shall, by a Responsible Officer of the Trustee, determine that the proceeding so directed would involve the Trustee in personal liability. 
  
 Section 6.13. Waiver of Past Defaults. 
  
 Subject to Section 6.2, 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 in the payment of the principal
of or interest on any Security of such Series (provided, however, that the Holders of a majority in principal amount of the outstanding Securities of any Series may rescind an acceleration and its consequences, including any related payment default
that resulted from such acceleration). Upon 

  

 22 








 
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; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 
  
 Section 6.14. Undertaking for Costs. 
  
 All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the outstanding Securities of any Series, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or interest on any Security on or after the Stated Maturity
or Stated Maturities expressed in such Security (or, in the case of redemption, on the redemption date).

 TRUSTEE 
  
 Section 7.1. Duties of Trustee. 
  
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the

 (b) Except during the continuance of an Event of Default: 
  
 (i) The Trustee need perform only those duties that are specifically set forth in this Indenture and no others.

rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon Officers’ Certificates or Opinions of Counsel furnished to the Trustee and conforming to the requirements of this Indenture; however, in the
case of any such Officers’ Certificates or Opinions of Counsel which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such Officers’ Certificates and Opinions of Counsel to

on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 
  
 (g) No provision of this Indenture shall require the Trustee to risk its own
funds or otherwise incur any financial liability in the performance of any of its duties, 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 is not reasonably assured to it. 
  
 (h) The Paying
Agent, the Registrar and any authenticating agent shall be entitled to the protections and immunities as are set forth in paragraphs (a), (b) and (c) of this Section with respect to the Trustee.

in good faith which it believes to be authorized or within its rights or powers.

indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction. 
  

 24 








 Section 7.3. Individual Rights of Trustee. 
  
 The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal
with the Company or an Affiliate with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. The Trustee is also subject to Sections 7.10 and 7.11. 
  
 Section 7.4. Trustee’s Disclaimer. 
  
 The Trustee makes no representation as to the validity or adequacy of this
Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement in the Securities other than its authentication. 
  
 Section 7.5. Notice of Defaults. 
  
 If a Default or Event of Default occurs and is continuing with respect to the
Securities of any Series and if it is known to a Responsible Officer of the Trustee, the Trustee shall mail to each Securityholder of the Securities of that Series and, if any Bearer Securities are outstanding, publish on one occasion in an
Authorized Newspaper, notice of a Default or Event of Default within 90 days after it occurs or, if later, after a Responsible Officer of the Trustee has knowledge of such Default or Event of Default. Except in the case of a Default or Event of
Default in payment of principal of or interest on any Security of any Series, the Trustee may withhold the notice if and so long as its corporate trust committee or a committee of its Responsible Officers in good faith determines that withholding
the notice is in the interests of Securityholders of that Series. 
  
 Section 7.6. Reports by Trustee to Holders. 
  
 Within 60
days after May 15 in each year, the Trustee shall transmit by mail to all Securityholders, as their names and addresses appear on the register kept by the Registrar and, if any Bearer Securities are outstanding, publish in an Authorized Newspaper, a
brief report dated as of such May 15, in accordance with, and to the extent required under, TIA Section 313. 
  
 A copy of each report at the time of its mailing to Securityholders of any Series shall be filed with the SEC and each stock exchange on which the
Securities of that Series are listed. The Company shall promptly notify the Trustee when Securities of any Series are listed on any stock exchange.

 The Company shall indemnify
the Trustee (including the cost of defending itself) against any loss, liability or expense incurred by it except as set forth in the next paragraph in the performance of its duties under this Indenture as Trustee or Agent. The Trustee shall notify
the Company promptly of any claim for which it may seek indemnity. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of

without its consent, which consent shall not be unreasonably withheld. This indemnification shall apply to officers, directors, employees, shareholders and
agents of the Trustee. 
  
 The Company need not reimburse any
expense or indemnify against any loss or liability incurred by the Trustee or by any officer, director, employee, shareholder or agent of the Trustee through negligence or bad faith. 
  
 To secure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Securities of
any Series on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Securities of that Series. 
  
 When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(e) or (f) occurs,
the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. 
  
 Section 7.8. Replacement of Trustee. 
  
 A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of
appointment as provided in this Section.

 (b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

Securityholder of the applicable Series may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
  
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company.
Immediately after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee subject to the lien provided for in Section 7.7, the resignation or removal

one occasion in an Authorized Newspaper. Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the Company’s obligations under Section 7.7 hereof shall continue for the benefit of the retiring trustee with respect to expenses
and liabilities incurred by it prior to such replacement.

supplemental indenture hereto for a particular Series of Securities or a Board Resolution or an Officers’ Certificate delivered pursuant to Section 2.2.21 (and the failure to comply with any such covenants shall not constitute a Default or

conditions shall have been satisfied:

recognized firm of independent certified public accountants expressed in a written certification thereof delivered to the Trustee, to pay principal and interest, if any, on and any mandatory sinking fund in respect of the Securities of such Series
on the dates such installments of interest or principal are due;

defeasance had not occurred; 
  
 (e) the Company shall have
delivered to the Trustee an Officers’ Certificate stating the deposit was not made by the Company with the intent of preferring the Holders of the Securities of such Series over any other creditors of the Company or with the intent of

Counsel, each stating that all conditions precedent herein provided for relating to the defeasance contemplated by this Section have been complied with. 
  
 Section 8.5. Repayment to Company. 
  
 The Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal and interest that remains
unclaimed for two years. After that, Securityholders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person. 
  
 Section 8.6. Reinstatement. 
  
 If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with Sections 8.1, 8.3 or 8.4, as the case may be, 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 Section 8.1, 8.3 or 8.4, as the case may be, until such time as the Trustee or
Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with Section 8.1, 8.3 or 8.4, as the case may be; provided, however, that if the Company makes any payment of principal of, premium, if any, or interest
on any Securities because of reinstatement of its obligations, the Company shall be subrogated to the rights of the holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

 (g) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA.

  

 31 








 Section 9.2. With Consent of Holders. 
  
 The Company and the Trustee may enter into a supplemental indenture with the written consent of the Holders of at least a
majority in principal amount of the outstanding Securities of each Series affected by such supplemental indenture (including consents obtained in connection with a tender offer or exchange offer for the Securities of such Series), for the purpose of
adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the Securityholders of each such Series. Except as provided in
Section 6.13, the Holders of at least a majority in principal amount of the outstanding Securities of each Series affected by such waiver by notice to the Trustee (including consents obtained in connection with a tender offer or exchange offer for
the Securities of such Series) may waive compliance by the Company with any provision of this Indenture or the Securities with respect to such Series. 
  
 It shall not be necessary for the consent of the Holders of Securities under this Section 9.2 to approve the particular form of any proposed supplemental
indenture or waiver, but it shall be sufficient if such consent approves the substance thereof. After a supplemental indenture or waiver under this Section becomes effective, the Company shall mail to the Holders of Securities affected thereby and,
if any Bearer Securities affected thereby are outstanding, publish on one occasion in an Authorized Newspaper, a notice briefly describing the supplemental indenture or waiver. Any failure by the Company to mail or publish such notice, or any defect
therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture or waiver. 
  
 Section 9.3. Limitations. 
  
 Without the consent of each Securityholder affected, an amendment or waiver may not: 
  
 (a) change the amount of Securities whose Holders must consent to an amendment, supplement or waiver; 
  
 (b) reduce the rate of or extend the time for payment of interest (including
default interest) on any Security; 
  
 (c) reduce the principal or
change the Stated Maturity of any Security or reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous obligation; 
  
 (d) reduce the principal amount of Discount Securities payable upon acceleration of the maturity thereof; 
  
 (e) waive a Default or Event of Default in the payment of the principal of or
interest, if any, on any Security (except a rescission of acceleration of the Securities of any Series by the Holders of at least a majority in principal amount of the outstanding Securities of such Series and a waiver of the payment default that
resulted from such acceleration); 
  
 (f) make the principal of or
interest, if any, on any Security payable in any currency other than that stated in the Security; 
  
 (g) make any change in Sections 6.8, 6.13, 9.3 (this sentence), 10.15 or 10.16; or 
  
 (h) waive a redemption payment with respect to any Security or change any of the provisions with respect to the redemption
of any Securities.

 Section 9.5. Revocation and Effect of Consents. 
  
 Until an amendment or waiver becomes effective, a consent to it by a Holder of a Security is a continuing consent by the Holder and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as
to his Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective. 
  
 Any amendment or waiver once effective shall bind every Securityholder of each Series affected by such amendment or waiver unless it is of the type
described in any of clauses (a) through (g) of Section 9.3. In that case, the amendment or waiver shall bind each Holder of a Security who has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder’s Security. 
  
 Section 9.6.
Notation on or Exchange of Securities. 
  
 The Trustee may place
an appropriate notation about an amendment or waiver on any Security of any Series thereafter authenticated. The Company in exchange for Securities of that Series may issue and the Trustee shall authenticate upon request new Securities of that
Series that reflect the amendment or waiver. 
  
 Section 9.7.
Trustee Protected. 
  
 In executing, or accepting the additional
trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 7.1) shall be fully protected in relying
upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee shall sign all supplemental indentures, except that the Trustee need not sign any supplemental indenture

 Unless otherwise specified in a Board Resolution, a supplemental indenture hereto or an Officers’ Certificate delivered pursuant to Section 2.2 of
this Indenture with respect to a particular Series of Securities, whenever for purposes of this Indenture any action may be taken by the Holders of a specified percentage in aggregate principal amount of Securities of all Series or all Series
affected by a particular action at the time outstanding and, at such time, there are outstanding Securities of any Series which are denominated in a coin or currency other than Dollars (including ECUs), then the principal amount of Securities of
such Series which shall be deemed to be outstanding for the purpose of taking such action shall be that amount of Dollars that could be obtained for such amount at the Market Exchange Rate at such time. For purposes of this Section 10.15,
“Market Exchange Rate” shall mean the noon Dollar buying rate in New York City for cable transfers of that currency as published by the Federal Reserve Bank of New York; provided, however, in the case of ECUs, Market Exchange Rate shall
mean the rate of exchange determined by the Commission of the European Union (or any successor thereto) as published in the Official Journal of the European Union (such publication or any successor publication, the “Journal”). If such
Market Exchange Rate is not available for any reason with respect to such currency, the Trustee shall use, in its sole discretion and without liability on its part, such quotation of the Federal Reserve Bank of New York or, in the case of ECUs, the
rate of exchange as published in the Journal, as of the most recent available date, or quotations or, in the case of ECUs, rates of exchange from one or more major banks in The City of New York or in the country of issue of the currency in question

equivalent principal amount in respect of Securities of a Series denominated in currency other than Dollars in connection with any action taken by Holders of Securities pursuant to the terms of this Indenture. 
  
 All decisions and determinations of the Trustee regarding the Market Exchange
Rate or any alternative determination provided for in the preceding paragraph shall be in its sole discretion and shall, 

  

 36 








 
in the absence of manifest error, be conclusive to the extent permitted by law for all purposes and irrevocably binding upon the Company and all Holders.

  
 Section 10.16. Judgment Currency. 
  
 The Company agrees, to the fullest extent that it may effectively do so under
applicable law, that (a) if for the purpose of obtaining judgment in any court it is necessary to convert the sum due in respect of the principal of or interest or other amount on the Securities of any Series (the “Required Currency”) into
a currency in which a judgment will be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in The City of New York the Required
Currency with the Judgment Currency on the day on which final unappealable judgment is entered, unless such day is not a New York Banking Day, then, the rate of exchange used shall be the rate at which in accordance with normal banking procedures
the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on the New York Banking Day preceding the day on which final unappealable judgment is entered and (b) its obligations under this Indenture to make
payments in the Required Currency (i) shall not be discharged or satisfied by any tender, any recovery pursuant to any judgment (whether or not entered in accordance with Subsection (a)), in any currency other than the Required Currency, except to
the extent that such tender or recovery shall result in the actual receipt, by the payee, of the full amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or additional
cause of action for the purpose of recovering in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full amount of the Required Currency so expressed to be payable, and (iii) shall not be affected by
judgment being obtained for any other sum due under this Indenture. For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a legal holiday in The City of New York on which banking institutions are
authorized or required by law, regulation or executive order to close. 
  
 ARTICLE XI. 
 SINKING FUNDS 
  
 Section 11.1. Applicability of Article. 
  
 The provisions of this Article shall be applicable to any sinking fund for the retirement of the Securities of a Series, except as otherwise permitted or
required by any form of Security of such Series issued pursuant to this Indenture. 
  
 The minimum amount of any sinking fund payment provided for by the terms of the Securities of any Series is herein referred to as a “mandatory sinking fund payment” and any other amount provided for by the
terms of Securities of such Series is herein referred to as an “optional sinking fund payment.” If provided for by the terms of Securities of any Series, the cash amount of any sinking fund payment may be subject to reduction as provided
in Section 11.2. Each sinking fund payment shall be applied to the redemption of Securities of any Series as provided for by the terms of the Securities of such Series. 
  
 Section 11.2. Satisfaction of Sinking Fund Payments with Securities. 
  
 The Company may, in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of any Series to be made pursuant to the terms of such Securities (1) deliver outstanding Securities of such Series to which such sinking fund payment is applicable (other than any of such Securities previously
called for mandatory sinking fund redemption) and (2) apply as credit Securities of such Series to which such sinking fund payment is applicable and which have been redeemed either at the election of the Company pursuant to the terms of such Series
of Securities (except pursuant to any 

  

 37 








 
mandatory sinking fund) or through the application of permitted optional sinking fund payments or other optional redemptions pursuant to the terms of such
Securities, provided that such Securities have not been previously so credited. Such Securities shall be received by the Trustee, together with an Officers’ Certificate with respect thereto, not later than 15 days prior to the date on which the
Trustee begins the process of selecting Securities for redemption, and shall be credited for such purpose by the Trustee at the price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking
fund payment shall be reduced accordingly. If as a result of the delivery or credit of Securities in lieu of cash payments pursuant to this Section 11.2, the principal amount of Securities of such Series to be redeemed in order to exhaust the
aforesaid cash payment shall be less than $100,000, the Trustee need not call Securities of such Series for redemption, except upon receipt of a Company Order that such action be taken, and such cash payment shall be held by the Trustee or a Paying
Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying Agent shall from time to time upon receipt of a Company Order pay over and deliver to the Company any cash payment so being held by the
Trustee or such Paying Agent upon delivery by the Company to the Trustee of Securities of that Series purchased by the Company having an unpaid principal amount equal to the cash payment required to be released to the Company. 
  
 Section 11.3. Redemption of Securities for Sinking Fund. 
  
 Not less than 45 days (unless otherwise indicated in the Board Resolution,
supplemental indenture hereto or Officers’ Certificate in respect of a particular Series of Securities) prior to each sinking fund payment date for any Series of Securities, the Company will deliver to the Trustee an Officers’ Certificate
specifying the amount of the next ensuing mandatory sinking fund payment for that Series pursuant to the terms of that Series, 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 of Securities of that Series pursuant to Section 11.2, and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and the Company shall thereupon be obligated to pay
the amount therein specified. Not less than 30 days (unless otherwise indicated in the Board Resolution, Officers’ Certificate or supplemental indenture in respect of a particular Series of Securities) before each such sinking fund payment date
the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 3.2 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner
provided in Section 3.3. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 3.4, 3.5 and 3.6. 
  
 [INCLUDE ARTICLE XII FOR SUBORDINATED SECURITIES... 
  

ARTICLE XII. 
 SUBORDINATION OF SECURITIES

  
 Section 12.1. Agreement of Subordination. 
  
 The Company covenants and agrees, and each Holder of Securities issued
hereunder by his acceptance thereof likewise covenants and agrees, that all Securities shall be issued subject to the provisions of this Article XII; and each Person holding any Security, whether upon original issue or upon transfer, assignment or
exchange thereof, accepts and agrees to be bound by such provisions. 
  
 The payment of the principal of, premium, if any, and interest on all Securities (including, but not limited to, the redemption price with respect to the Securities called for redemption in accordance with Article 3 as provided in the
Indenture) issued hereunder shall, to the extent and in the manner hereinafter 

  

 38 








 
set forth, be subordinated and subject in right of payment to the prior payment in full of all Senior Indebtedness, whether outstanding at the date of this
Indenture or thereafter incurred. 
  
 No provision of this Article
XII shall prevent the occurrence of any default or Event of Default hereunder. 
  
 Section 12.2. Payments to Holders. 
  
 No payment shall be made with respect to the principal of, or premium, if any, or interest on the Securities (including, but not limited to, the redemption price with respect to the Securities to be called for redemption in accordance with
Article III as provided in the Indenture), except payments and distributions made by the Trustee as permitted by the first or second paragraph of Section 12.5, if: 
  
 (i) a default in the payment of principal, premium, interest, rent or other obligations due on any Senior Indebtedness
occurs and is continuing (or, in the case of Senior Indebtedness for which there is a period of grace, in the event of such a default that continues beyond the period of grace, if any, specified in the instrument or lease evidencing such Senior
Indebtedness), unless and until such default shall have been cured or waived or shall have ceased to exist; or 
  
 (ii) a default, other than a payment default, on a Designated Senior Indebtedness occurs and is continuing that then permits holders of such Designated
Senior Indebtedness to accelerate its maturity and the Trustee receives a notice of the default (a “Payment Blockage Notice”) from a Representative or the Company. 
  
 If the Trustee receives any Payment Blockage Notice pursuant to clause (ii) above, no subsequent Payment Blockage Notice
shall be effective for purposes of this Section unless and until (a) at least 365 days shall have elapsed since the initial effectiveness of the immediately prior Payment Blockage Notice, and (b) all scheduled payments of principal, premium, if any,
and interest on the Securities that have come due have been paid in full in cash. No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice. 
  
 The Company may and shall
resume payments on and distributions in respect of the Securities upon the earlier of: 
  
 (1) the date upon which the default is cured or waived or ceases to exist, or 
  
 (2) in the case of a default referred to in clause (ii) above, 179 days pass after notice is received if the maturity of such Designated Senior
Indebtedness has not been accelerated, unless this Article XII otherwise prohibits the payment or distribution at the time of such payment or distribution. 
  
 Upon any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors
upon any dissolution or winding-up or liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings, all amounts due or to become due upon all Senior Indebtedness shall
first be paid in full in cash or other payment satisfactory to the holders of such Senior Indebtedness, or payment thereof in accordance with its terms provided for in cash or other payment satisfactory to the holders of such Senior Indebtedness,
before any payment is made on account of the principal of, premium, if any, or interest on the Securities (except payments made pursuant to Article VI from monies deposited with the Trustee pursuant thereto prior to commencement of proceedings for
such dissolution, winding-up, liquidation or reorganization); and upon any such dissolution or winding-up or 

  

 39 








 
liquidation or reorganization of the Company or bankruptcy, insolvency, receivership or other proceeding, any payment by the Company, or distribution of
assets of the Company of any kind or character, whether in cash, property or securities, to which the Holders of the Securities or the Trustee would be entitled, except for the provision of this Article XII, shall (except as aforesaid) be paid by
the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the Holders of the Securities or by the Trustee under this Indenture if received by them or it, directly to
the holders of Senior Indebtedness (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness held by such holders, or as otherwise required by law or a court order) or their representative or representatives, or to the
trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay all Senior Indebtedness in full, in cash or
other payment satisfactory to the holders of such Senior Indebtedness, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness, before any payment or distribution or provision therefor is made to
the Holders of the Securities or to the Trustee. 
  
 For purposes
of this Article XII, the words, “cash, property or securities” shall not be deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of
reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this Article XII with respect to the Securities to the payment of all Senior Indebtedness which may at the time be outstanding; provided that (i)
the Senior Indebtedness is assumed by the new corporation, if any, resulting from any reorganization or readjustment, and (ii) the rights of the holders of Senior Indebtedness (other than leases which are not assumed by the Company or the new
corporation, as the case may be) are not, without the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another corporation or the liquidation or
dissolution of the Company following the conveyance or transfer of its property as an entirety, or substantially as an entirety, to another corporation upon the terms and conditions provided for in Article V shall not be deemed a dissolution,
winding-up, liquidation or reorganization for the purposes of this Section 12.2 if such other corporation shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions stated in Article V. 
  
 In the event of the acceleration of the Securities because of an Event of
Default, no payment or distribution shall be made to the Trustee or any Holder of Securities in respect of the principal of, premium, if any, or interest on the Securities (including, but not limited to, the redemption price with respect to the
Securities called for redemption in accordance with Article 3 as provided in the Indenture), except payments and distributions made by the Trustee as permitted by the first or second paragraph of Section 12.5, until all Senior Indebtedness has been
paid in full in cash or other payment satisfactory to the holders of Senior Indebtedness or such acceleration is rescinded in accordance with the terms of this Indenture. If payment of the Securities is accelerated because of an Event of Default,
the Company shall promptly notify holders of Senior Indebtedness of the acceleration at the address set forth in the notice from the Agent (or successor agent) to the Trustee as being the address to which the Trustee should send its notice pursuant
to this Section 12.2, unless there are no payment obligations of the Company thereunder and all obligations thereunder to extend credit have been terminated or expired. 
  
 In the event that, notwithstanding the foregoing provisions, any payment or distribution of assets of the Company of any
kind or character, whether in cash, property or securities (including, without limitation, by way of setoff or otherwise), prohibited by the foregoing, shall be received by the Trustee or the Holders of the Securities before all Senior Indebtedness
is paid in full in cash or other payment satisfactory to the holders of such Senior Indebtedness, or provision is made for such payment thereof in accordance with its terms in cash or other payment satisfactory to the holders of such Senior
Indebtedness, such payment or distribution shall be held in trust for the benefit of and shall be paid over 

  

 40 








 
or delivered to the holders of Senior Indebtedness or their representative or representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, as calculated by the Company, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary
to pay all Senior Indebtedness in full in cash or other payment satisfactory to the holders of such Senior Indebtedness, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness. 
  
 Nothing in this Section 12.2 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 7.7. This Section 12.2 shall be subject to the further provisions of Section 12.5. 
  
 Section 12.3. Subrogation of Securities. 
  
 Subject to the payment in full of all Senior Indebtedness, the rights of the Holders of the Securities shall be subrogated to the extent of the payments
or distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article XII (equally and ratably with the holders of all indebtedness of the Company which by its express terms is subordinated to other indebtedness
of the Company to substantially the same extent as the Securities are subordinated and is entitled to like rights of subrogation) to the rights of the holders of Senior Indebtedness to receive payments or distributions of cash, property or
securities of the Company applicable to the Senior Indebtedness until the principal, premium, if any, and interest on the Securities shall be paid in full; and, for the purposes of such subrogation, no payments or distributions to the holders of the
Senior Indebtedness 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 XII, and no payment over pursuant to the provisions of this Article XII, to or
for the benefit of the holders of Senior Indebtedness by Holders of the Securities or the Trustee, shall, as between the Company, its creditors other than holders of Senior Indebtedness, and the Holders of the Securities, be deemed to be a payment
by the Company to or on account of the Senior Indebtedness; and no payments or distributions of cash, property or securities to or for the benefit of the Holders of the Securities pursuant to the subrogation provisions of this Article XII, which
would otherwise have been paid to the holders of Senior Indebtedness shall be deemed to be a payment by the Company to or for the account of the Securities. It is understood that the provisions of this Article XII are and are intended solely for the
purposes of defining the relative rights of the Holders of the Securities, on the one hand, and the holders of the Senior Indebtedness, on the other hand. 
  
 Nothing contained in this Article XII or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its
creditors other than the holders of Senior Indebtedness, and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Securities the principal of (and premium, if any) and
interest on the Securities as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders of the Securities and creditors of the Company other than the holders
of the Senior Indebtedness, nor shall anything herein or therein 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 XII of the holders of Senior Indebtedness in respect of cash, property or securities of the Company received upon the exercise of any such remedy. 
  
 Upon any payment or distribution of assets of the Company referred to in this Article XII, the Trustee, subject to the
provisions of Section 7.1, and the Holders of the Securities shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings
are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or 

  

 41 








 
distribution, delivered to the Trustee or to the Holders of the Securities, for the purpose of ascertaining the persons entitled to participate in such
distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon and all other facts pertinent thereto or to this Article XII. 
  
 Section 12.4. Authorization to Effect Subordination. 
  
 Each Holder of a Security by the holder’s acceptance thereof authorizes
and directs the Trustee on the holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article XII and appoints the Trustee to act as the holder’s attorney-in-fact for any
and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 6.3 hereof at least 30 days before the expiration of the time to file such claim, the holders
of any Senior Indebtedness or their representatives are hereby authorized to file an appropriate claim for and on behalf of the Holders of the Securities. 
  
 Section 12.5. Notice to Trustee. 
  
 The Company shall give prompt written notice in the form of an Officers’ Certificate to a Responsible Officer of the Trustee and to any paying agent
of any fact known to the Company which would prohibit the making of any payment of monies to or by the Trustee or any paying agent in respect of the Securities pursuant to the provisions of this Article XII. Notwithstanding the provisions of this
Article XII 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 of monies to or by the Trustee in respect of the Securities pursuant
to the provisions of this Article XII, unless and until a Responsible Officer of the Trustee shall have received written notice thereof at the Corporate Trust Office from the Company (in the form of an Officers’ Certificate) or a Representative
or a holder or holders of Senior Indebtedness or from any trustee thereof; and before the receipt of any such written notice, the Trustee, subject to the provisions of Section 7.1, shall be entitled in all respects to assume that no such facts
exist; provided that if on a date not fewer than two Business Days prior to the date upon which by the terms hereof any such monies may become payable for any purpose (including, without limitation, the payment of the principal of, or premium, if
any, or interest on any Security) the Trustee shall not have received, with respect to such monies, the notice provided for in this Section 12.5, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such monies and to apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may be received by it on or after such prior date. 
  
 Notwithstanding anything in this Article XII to the contrary, nothing shall
prevent any payment by the Trustee to the Holders of monies deposited with it pursuant to Section 8.1, and any such payment shall not be subject to the provisions of Section 12.1 or 12.2. 
  
 The Trustee, subject to the provisions of Section 7.1, shall be entitled to rely on the delivery to it of a written notice
by a Representative or a person representing himself to be a holder of Senior Indebtedness (or a trustee on behalf of such holder) to establish that such notice has been given by a Representative or a holder of Senior Indebtedness or a trustee on
behalf of any such holder or holders. 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 Indebtedness to participate in any payment or distribution
pursuant to this Article XII, the Trustee may request such person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness 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 XII, and if such evidence is not furnished the Trustee may 

  

 42 








 
defer any payment to such person pending judicial determination as to the right of such person to receive such payment. 
  
 Section 12.6. Trustee’s Relation to Senior Indebtedness. 
  
 The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article XII in respect of any Senior Indebtedness at any time held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in Section 7.11 or elsewhere in this Indenture shall deprive the Trustee of any of
its rights as such holder. 
  
 With respect to the holders of
Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article XII, and no implied covenants or obligations with respect to the holders of Senior
Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and, subject to the provisions of Section 7.1, the Trustee shall not be liable to any
holder of Senior Indebtedness if it shall pay over or deliver to Holders of Securities, the Company or any other person money or assets to which any holder of Senior Indebtedness shall be entitled by virtue of this Article XII or otherwise.

  
 Section 12.7. No Impairment of Subordination. 
  
 No right of any present or future holder of any Senior Indebtedness 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 which any such holder may have or otherwise be charged with. 
  
 Section 12.8. Article Applicable to Paying Agents. 
  
 If 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 (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 the first paragraph of Section 12.5 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent.

  
 Section 12.9. Senior Indebtedness Entitled to Rely.

  
 The holders of Senior Indebtedness (including, without
limitation, Designated Senior Indebtedness) shall have the right to rely upon this Article XII, and no amendment or modification of the provisions contained herein shall diminish the rights of such holders unless such holders shall have agreed in
writing thereto.
