so disregarded. Notes so owned which have been pledged in good faith may be regarded as Outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Notes and that the pledgee is
not the Company or any other obligor upon the Notes or any Subsidiary of the Company or of such other obligor.

Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments signed by such Holders in person or by an agent duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or
instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the
“Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Note, shall be sufficient for any purpose of this
Indenture and (subject to Section 501) conclusive in favor of the Trustee and the Company and any agent of the Trustee or the Company, if made in the manner provided in this Section. 

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 which the Trustee deems sufficient. 

  
 9 








 The ownership, principal amount and serial number of the Notes shall be proved by the Note Register. 

Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note
and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not
notation of such action is made upon such Note. 
 The Company may, in the circumstances permitted by the Trust Indenture Act, set any day as the record
date for the purpose of determining the Holders of the Outstanding Notes entitled to give or take any request, demand, authorization, direction, notice, consent, waiver or other action or permitted by this Indenture to be given or taken by Holders
of the Notes. With regard to any record date set pursuant to this paragraph, the Holders of the Outstanding Notes on such record date (or their duly appointed agents), and only such Persons, shall be entitled to give or take the relevant action,
whether or not such Holders remain Holders after such record date. With regard to any action that may be given or taken hereunder only by Holders of a requisite principal amount of the Outstanding Notes (or their duly appointed agents) and for which
a record date is set pursuant to this paragraph, the Company may, at its option, set an expiration date after which no such action purported to be given or taken by any Holder shall be effective hereunder unless given or taken on or prior to such
expiration date by Holders of the requisite principal amount of the Outstanding Notes on such record date (or their duly appointed agents). On or prior to any expiration date set pursuant to this paragraph, the Company may, on one or more occasions
at its option, extend such date to any later date. Nothing in this paragraph shall prevent any Holder (or any duly appointed agent thereof) from giving or taking, after any expiration date, any action identical to, or, at any time, contrary to or
different from, any action given or taken, or purported to have been given or taken, hereunder by a Holder on or prior to such date, in which event the Company may set a record date in respect thereof pursuant to this paragraph. Notwithstanding the
foregoing or the Trust Indenture Act, the Company shall not set a record date for, and the provisions of this paragraph shall not apply with respect to, any action to be given or taken by Holders pursuant to Sections 401, 402 or 412. 

Without limiting the foregoing, a Holder entitled hereunder to give or take any action hereunder with regard to any particular Note may do so with regard to
all or any part of the principal amount of such Note or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any different part of such principal amount.

 Section 105. Notices, Etc., to Trustee and 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 shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, or 


 

	 	(2)	the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to
it to the attention of its Treasurer at the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company. 


The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, pdf, facsimile transmission
or other similar unsecured electronic methods, provided, however, that the Trustee shall have received an incumbency certificate listing persons designated to give such instructions or directions and containing specimen signatures of such
designated persons, which such incumbency certificate shall be amended and replaced whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee e-mail or facsimile instructions (or instructions by a
similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s understanding of such instructions shall be deemed controlling. The Trustee shall not be liable for any losses, costs or expenses
arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions notwithstanding such instructions conflict or are inconsistent with a subsequent written instruction. The Company agrees to assume all risks
arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized instructions, and the risk of interception and misuse by third
parties. 
 Section 106. Notice to Holders; Waiver. 

Except as otherwise expressly provided in or pursuant to this Indenture, where this Indenture provides for notice to Holders of the Notes of any event, such
notice shall be sufficiently given to Holders of the Notes if in writing and mailed, first-class postage prepaid, to each Holder of a Note affected by such event, at his address as it appears in the Note Register, not later than the latest date, and
not earlier than the earliest date, prescribed for the giving of such notice. 
 In any case where notice to Holders of the Notes is given by mail, neither
the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Note shall affect the sufficiency of such notice with respect to other Holders of Notes given as provided herein. Any notice which is mailed in
the manner herein provided shall be conclusively presumed to have been duly given or provided. 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. 

  
 11 








 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 of the Notes 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. 
 Section 107. Conflict with Trust Indenture Act. 

If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part of and govern
this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture
as so modified or to be excluded, as the case may be. 
 Section 108. 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.

 All covenants
and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not. 
 Section 110. Separability
Clause. 
 In case any provision in this Indenture or any Note 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 111. Benefits of Indenture. 

Nothing in this Indenture or the Notes, express or implied, shall give to any Person (including any Paying Agent or Authenticating Agent appointed pursuant to
Section 514), other than the parties hereto and their successors hereunder and the Holders of the Notes, any benefit or any legal or equitable right, remedy or claim under this Indenture. 

Section 112. Governing Law. 
 This Indenture and the
Notes shall be governed by and construed in accordance with the laws of the State of New York (including Section 5-1401 of the General Obligations Law of the State of New York but otherwise without regard to principles of conflicts of laws).


  
 12 








 Section 113. Legal Holidays. 

In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Note shall not be a Business Day at the Place of Payment, then
(notwithstanding any other provision of this Indenture or any Note) payment of interest or principal (and premium, if any) need not be made at the Place of Payment on such date, but may be made on the next succeeding Business Day at the Place of
Payment with the same force and effect as if made on the Interest Payment Date, Redemption Date or at the Stated Maturity, provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date or
Stated Maturity, as the case may be. 
 Section 114. Waiver of Jury Trial. 

EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY
LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY. 
 Section 115. Force Majeure.

 In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused
by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions,
loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume
performance as soon as practicable under the circumstances. 
 ARTICLE TWO 

The Notes 
 Section 201. Form

 The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto. The Notes may have
notations, legends or endorsements required by law, stock exchange rule or usage. The Company shall approve the form of the Notes and any notation, legend or endorsement on them. Each Note shall show the date of its authentication. 

The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the
Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. 

The Notes shall be issued initially in the form of a single permanent global Note in registered form, substantially in the form set forth in Exhibit
A (the “Initial Global Notes”), deposited with the Trustee, as custodian for the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided and shall bear the legend set forth in Exhibit
B.  

  
 13 








 The Notes issued after the Issue Date shall be issued (a) initially in the form of one or more global
Notes in registered form, substantially in the form set forth in Exhibit A, deposited with the Trustee, as custodian for the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided and shall bear any
legends required by applicable law (together with the Initial Global Notes, the “Global Notes”) or (b) as Physical Notes.  

The aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records of the Trustee,
as custodian for the Depository, as hereinafter provided. Notes issued in exchange for interests in a Global Note pursuant to Section 205 may be issued in the form of permanent certificated Notes in registered form in substantially the form set
forth in Exhibit A and bearing the applicable legends, if any (the “Physical Notes”).  
 Additional Notes ranking
pari passu with the Initial Notes may be created and issued from time to time by the Company without notice to or consent of the Holders and shall be consolidated with and form a single class with the Initial Notes and shall
have the same terms as to status, redemption or otherwise (other than with respect to the purchase price thereof and the date from which the interest accrues) as the Initial Notes. The Initial Notes and any Additional Notes subsequently issued under
this Indenture will be treated as a single class for all purposes under this Indenture, including waivers, amendments, redemptions and offers to purchase, and shall vote together as one class on all matters with respect to the Notes; provided
further that if the Additional Notes are not fungible with the Notes for U.S. Federal income tax purposes the Additional Notes will have a separate “CUSIP” number, if applicable. Unless the context requires otherwise, references to
“Notes” for all purposes of this Indenture include any Additional Notes that are actually issued. 
 Section 202.
Denominations. 
 The Notes shall be issuable only in registered form without coupons in minimum denominations of $2,000 and integral multiples of
$1,000 in excess thereof. 
 Section 203. Execution, Authentication, Delivery and Dating. 

The Notes shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the Board, its President or one of its Vice Presidents
and attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Notes may be manual or facsimile. 
 Notes
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 Notes or did not hold such offices at the date of such Notes. 
 Each Note shall be dated the date of its
authentication. 

  
 14 








 No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless
there appears on such Note a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such
Note has been duly authenticated and delivered hereunder. 
 The Trustee shall authenticate (i) on the Issue Date, Notes for original issue in
the aggregate principal amount not to exceed $250,000,000.00 (the “Initial Notes”) and (ii) additional Notes (the “Additional Notes”) in an unlimited amount in each case upon an Authentication Order. Each such
Authentication Order shall specify the amount of Notes to be authenticated and the date on which the Notes are to be authenticated, whether the Notes are to be Initial Notes or Additional Notes and whether the Notes are to be issued as Physical
Notes or Global Notes or such other information as the Trustee may reasonably request.  
 All Notes issued under this Indenture shall be treated as
a single class for all purposes under this Indenture. The Additional Notes shall bear any legend required by applicable law. 
 Notwithstanding the
foregoing, if any Note shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Note to the Trustee for cancellation as provided in Section 209, for all purposes of this
Indenture such Note shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. 

Section 204. Temporary Notes. 
 Pending the
preparation of definitive Notes, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, in registered form without coupons and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes may determine, as evidenced by their execution of such Notes. 

Every temporary Note shall be executed by the Company and authenticated by the Trustee and registered by the Note Registrar, upon the same conditions, and
with like effect, as a definitive Note. 
 If temporary Notes are issued, the Company will cause definitive Notes to be prepared without unreasonable delay.
After the preparation of definitive Notes, the temporary Notes shall be exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency of the Company in the Place of Payment, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Notes, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more definitive Notes, of any authorized denominations and of a like aggregate
principal amount. Until so exchanged the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as definitive Notes. 

  
 15 








 Section 205. Registration, Registration of Transfer and Exchange. 

The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other
office or agency of the Company in the Place of Payment being herein sometimes collectively referred to as the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the
registration of Notes and of transfers of Notes. The Trustee is hereby appointed “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. 

Upon surrender for registration of transfer of any Note at the office or agency in the Place of Payment, the Company shall execute, and the Trustee, upon
receipt of an Authentication Order, shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes, of any authorized denominations and of a like aggregate principal amount. 

At the option of the Holder, the Notes may be exchanged for other Notes, of any authorized denominations and of a like aggregate principal amount, upon
surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Holder making the exchange is
entitled to receive. 
 All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Company, evidencing
the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange. 
 Every
Note 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 Note
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 Notes, but the Company 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 Notes, other than exchanges
pursuant to Section 204, 806 or 1007 not involving any transfer. 
 The Company shall not be required (1) to issue, register the transfer of or
exchange Notes during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of the Notes selected for redemption under Section 1003 and ending at the close of business on the day of such
mailing, or (2) to register the transfer or exchange of any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 

Notwithstanding any other provision in this Indenture, no Global Note may be transferred to, or registered or exchanged for Notes registered in the name of,
any Person other than the Depositary for such Global Note or any nominee thereof, and no such transfer may be registered, unless (1) such Depositary (A) notifies the Company that it is unwilling or unable to continue as Depositary for such
Global Note or (B) ceases to be a clearing agency registered under the Exchange Act, (2) the Company executes and delivers to the Trustee a Company Order that such Global Note shall be so transferable, registrable and exchangeable, and
such transfers shall be 

  
 16 








 
registrable, (3) there shall have occurred and be continuing an Event of Default with respect to the Notes evidenced by such Global Note. Notwithstanding any other provision in this
Indenture, a Global Note to which the restriction set forth in the preceding sentence shall have ceased to apply may be transferred only to, and may be registered and exchanged for Physical Notes registered only in the name or names of, such Person
or Persons as the Depositary for such Global Note shall have directed and no transfer thereof other than such a transfer may be registered. 
 Every Note
authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Note to which the restriction set forth in the first sentence of the preceding paragraph shall apply, whether pursuant to this Section,
Section 204, 206, 806 or 1007 or otherwise, shall be authenticated, registered and delivered in the form of, and shall be, a Global Note. 

Section 206. Mutilated, Destroyed, Lost and Stolen Notes. 

If any mutilated Note is surrendered to the Trustee, the Company shall execute and the Trustee shall, upon receipt of an Authentication Order, authenticate
and deliver in exchange therefor a new Note and of like 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 Note 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 Note has been acquired by a bona fide purchaser, the Company shall execute and the Trustee shall, upon receipt of an Authentication Order, authenticate and deliver, in
lieu of any such destroyed, lost or stolen Note, a new Note of like principal amount and bearing a number not contemporaneously outstanding. 
 In case any
such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note. 

Upon the issuance of any new Note 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 Note
issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Note, shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Note 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 Notes. 
 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 Notes.

 Section 207. Payment of Interest; Interest Rights Preserved. 

Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name
that Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest. 
 Any interest on
any Note which is payable, but is not punctually 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 Notes (or their respective Predecessor Notes) 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 Note 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 satisfactory to the Trustee for such deposit on or prior to
the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of
such Defaulted Interest which shall 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 mailed, first-class postage
prepaid, to each Holder of the Notes at his address as it appears in the Note Register, 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 Notes (or their respective Predecessor Notes) are registered at the close of business on such Special Record Date. 


 

	 	(2)	The Company may make payment of any Defaulted Interest on the Notes in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Notes may be listed, and upon such notice as
may be required by such exchange, if, after notice is given by the Company to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee. 


  
 18 








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

Section 208. Persons Deemed Owners. 
 Prior to due
presentment of a Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of
principal of and any premium and (subject to Section 207) any interest on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary. 
 None of the Company, the Trustee, any Paying Agent or the Note Registrar will have any responsibility or
liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

Section 209. Cancellation. 
 All Notes surrendered
for payment, redemption, registration of transfer or exchange 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 Notes 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 Notes
previously authenticated hereunder which the Company has not issued and sold, and all Notes so delivered shall be promptly cancelled by the Trustee. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in
this Section, except as expressly permitted by this Indenture. All cancelled Notes held by the Trustee shall be disposed of in accordance with the Trustee’s customary procedures. 

Section 210. Computation of Interest. 
 Interest on
the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. 
 Section 211. CUSIP Numbers. 

The Company in issuing the Notes shall use “CUSIP” numbers (if then generally in use) and 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 Notes or as contained in any notice of a redemption and
that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of any
change in the “CUSIP” numbers.

 ARTICLE THREE 

Satisfaction and Discharge 

Section 301. Satisfaction and Discharge of Indenture. 

This Indenture shall upon Company Request cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Notes
herein expressly provided for), 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 Notes theretofore authenticated and delivered (other than (i) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 206, and (ii) Notes 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 903) have been delivered to the Trustee for
cancellation; or 

  

	 	(B)	all such Notes 

  

	 	(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, in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in
trust for the purpose an amount sufficient to pay and discharge the entire indebtedness on such Notes 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
Notes which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; 
  

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

  

	 	(3)	the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this
Indenture have been complied with. 


  
 20 








 Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee
under Section 507, the obligations of the Trustee to any Authenticating Agent under Section 514 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 302 and the last paragraph of Section 903 shall survive such satisfaction and discharge. 
 Section 302.
Application of Trust Money. 
 Subject to provisions of the last paragraph of Section 903, all money deposited with the Trustee pursuant to
Section 301 shall be held in trust and applied by it, in accordance with the provisions of the Notes 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. 

ARTICLE FOUR 
 Events of
Default; Remedies 
 Section 401. Events of Default. 

“Event of Default”, wherever used herein, means any one of the following events (whatever the reason for such Event of Default and
whether it be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): 

 

	 	(1)	default in the payment of any interest upon any Note when it becomes due and payable, and continuance of such default for a period of 30 days; or 


 

	 	(2)	default in the payment of the principal of (or premium, if any, on) any Note at its Maturity; or 

  

	 	(3)	default in the performance, or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section
specifically dealt with), and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25%
in principal amount of the Outstanding Notes, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or 


 

	 	(4)	 a default under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company in an individual principal amount
outstanding of at least $50,000,000 or under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company in an individual principal amount
outstanding of at least $50,000,000, whether such indebtedness now 



  
 21 









	 	
exists or shall hereafter be created, which default shall constitute a failure to pay $50,000,000 or more of the principal of such indebtedness when due and payable after the expiration of any
applicable grace period with respect thereto or which default shall have resulted in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, without such payment being
made in full or such acceleration having been rescinded or annulled, within a period of 30 days after there shall have been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at
least 25% in principal amount of the Outstanding Notes a written notice specifying such default and requiring the Company to cause such payment to be made in full or such acceleration to be rescinded or annulled and stating that such notice is a
“Notice of Default” hereunder; provided, however, that, subject to the provisions of Sections 501 and 502, the Trustee shall not be deemed to have knowledge of such default unless either (A) a Responsible Officer of the
Trustee shall have actual knowledge of such default or (B) the Trustee shall have received at its Corporate Trust Office written notice thereof from the Company, from any Holder, from the holder of any such indebtedness or from the trustee
under any such mortgage, indenture or other instrument referencing this Indenture; or 

  

	 	(5)	the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy,
insolvency, reorganization or other similar law or (B) a decree or order adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of
the Company under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or ordering the winding up
or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; or 


 

	 	(6)	the commencement by the Company of a voluntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a
bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law
or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State law, or the consent by it to the
filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or the making by it of
an assignment for the benefit of creditors, or the taking of corporate action by the Company in furtherance of any such action. 


  
 22 








 Upon receipt by the Trustee of any Notice of Default pursuant to this Section 401, a record date
shall automatically and without any other action by any Person be set for the purpose of determining the Holders of the Outstanding Notes entitled to join in such Notice of Default, which record date shall be the close of business on the day the
Trustee receives such Notice of Default. The Holders of the Outstanding Notes on such record date (or their duly appointed agents), and only such Persons, shall be entitled to join in such Notice of Default, whether or not such Holders remain
Holders after such record date; provided that, unless such Notice of Default shall have become effective by virtue of Holders of the requisite principal amount of the Outstanding Notes on such record date (or their duly appointed agents)
having joined therein on or prior to the 90th day after such record date, such Notice of Default shall automatically and without any action by any Person be cancelled and of no further effect. Nothing in this paragraph shall prevent a Holder (or a
duly appointed agent thereof) from giving, before or after the expiration of such 90-day period, a Notice of Default contrary to or different from, or, after the expiration of such period, identical to, a Notice of Default that has been cancelled
pursuant to the proviso to the preceding sentence, in which event a new record date in respect thereof shall be set pursuant to this paragraph. 

Section 402. Acceleration of Maturity; Rescission and Annulment. 

If an Event of Default occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Notes may declare the principal amount of all of the Notes 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. 
 At any time after such a declaration of acceleration 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 Notes, by written notice to the Company and the Trustee, may rescind and
annul such declaration and its consequences if all Events of Default with respect to the Notes, other than the non-payment of the principal of the Notes which have become due solely by such declaration of acceleration, have been cured or waived as
provided in Section 413. 
 No such rescission shall affect any subsequent default or impair any right consequent thereon. 

Upon receipt by the Trustee of any declaration of acceleration, or any rescission and annulment of any such declaration pursuant to this Section 402, a
record date shall automatically and without any other action by any Person be set for the purpose of determining the Holders of the Outstanding Notes entitled to join in such declaration, or rescission and annulment, as the case may be, which record
date shall be the close of business on the day the Trustee receives such declaration, or rescission and annulment, as the case may be. The Holders of the Outstanding Notes on such record date (or their duly appointed agents), and only such Persons,
shall be entitled to join in such declaration, or rescission and annulment, as the case may be, whether or not such Holders remain Holders after such record date; provided that, unless such declaration, or rescission an annulment, as the case
may be, shall have become effective by virtue of Holders of the requisite principal amount of the Outstanding Notes on such record date (or their duly appointed agents) having joined therein on or prior to the 90th day after such record date, such


  
 23 








 
declaration, or rescission and annulment, as the case may be, shall automatically and without any action by any Person be cancelled and of no further effect. Nothing in this paragraph shall
prevent a Holder (or a duly appointed agent thereof) from giving, before or after the expiration of such 90-day period, a declaration of acceleration, or a rescission and annulment of any such declaration, contrary to or different from, or, after
the expiration of such period, identical to, a declaration, or rescission and annulment, as the case may be, that has been cancelled pursuant to the proviso to the preceding sentence, in which event a new record date in respect thereof shall be set
pursuant to this paragraph. 
 Section 403. 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 Note 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 Note at the Maturity thereof, 


the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes 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 the Notes,
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 the Notes occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the
rights of the Holders of the Notes by such appropriate judicial proceedings as the Trustee shall deem most effective 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 404. Trustee May File Proofs of Claim. 

In case of any judicial proceeding relative to the Company (or any other obligor upon the Notes), its property or its creditors, 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 507. 

  
 24 








 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 Notes 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. 

Section 405. Trustee May Enforce Claims Without Possession of Notes. 

All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes 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 Notes in respect of which such judgment has been recovered. 

Section 406. Application of Money Collected. 
 Any
money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee: 
 FIRST: To the
payment of all amounts due the Trustee under Section 507; and 
 SECOND: To the payment of the amounts then due and unpaid for principal of and any
premium and interest on the Notes 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 the Notes for principal and any premium
and interest, respectively. 
 THIRD: To the Company or to such other person as a court of competent jurisdiction shall direct. 

Section 407. Limitation on Suits. 
 No Holder of any
Note 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; 

  

	 	(2)	the Holders of not less than 25% in principal amount of the Outstanding Notes 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 indemnity satisfactory to it against the costs, expenses and liabilities to be incurred in complying with such request in such amount as shall be reasonably acceptable
to the Trustee; and 


  
 25 









	 	(4)	for 60 days after its receipt of such notice, the Trustee has failed to institute a proceeding and 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 Notes; 

 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 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. 

Section 408. Unconditional Right of Holders to Receive Principal, Premium and Interest. 

Notwithstanding any other provision in this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment of
the principal of and any premium and (subject to Section 207) interest on such Note on the respective Stated Maturities expressed in such Note (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of
such right, and such right shall not be impaired without the consent of such Holder. 
 Section 409. 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 410. Rights and Remedies Cumulative. 

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of
Section 206, 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 411. Delay or Omission Not Waiver. 

No delay or omission of the Trustee or of any Holder of any Notes 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. 

  
 26 








 Section 412. Control by Holders. 

The Holders of a majority in principal amount of the Outstanding Notes shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercise any trust or power conferred on the Trustee, with respect to the Notes, provided that 
  

	 	(1)	such direction shall not be in conflict with any rule of law or with this Indenture, and 

  

	 	(2)	such direction may not involve the Trustee in personal liability if the Trustee believes indemnity is not adequate. 


The Trustee may also take any other action deemed proper by the Trustee which is not inconsistent with such direction. 

Upon receipt by the Trustee of any such direction with respect to the Notes, a record date shall automatically and without any other action by any
Person be set for determining the Holders of the Outstanding Notes entitled to join in such direction, which record date shall be the close of business on the day the Trustee receives such direction. The Holders of the Outstanding Notes on such
record date (or their duly appointed agents), and only such Persons, shall be entitled to join in such direction, whether or not such Holders remain Holders after such record date; provided that, unless such direction shall have become
effective by virtue of the Holders of the requisite principal amount of the Outstanding Notes on such record date (or their duly appointed agents having joined therein on or prior to the 90th day after such record date), such direction shall
automatically and without any action by any Person be cancelled and of no further effect. Nothing in this paragraph shall prevent a Holder (or a duly appointed agent thereof) from giving, before or after the expiration of such 90-day period, a
direction contrary to or different from, or, after the expiration of such period, identical to, a direction that has been cancelled pursuant to the proviso to the preceding sentence, in which event a new record date in respect thereof shall be set
pursuant to this paragraph. 
 Section 413. Waiver of Past Defaults. 

The Holders of not less than a majority in principal amount of the Outstanding Notes may on behalf of the Holders of all the Notes waive any past default
hereunder and its consequences, except a default 
  

	 	(1)	in the payment of the principal of or any premium or interest on any Note, or 

  

	 	(2)	in respect of a covenant or provision hereof which under Article Eight cannot be amended without the consent of the Holder of each Outstanding Note affected. 


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; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 

  
 27 








 Section 414. 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 (including attorneys’ fees and expenses), and may assess costs against any such party litigant, in the manner and
to the extent provided in the Trust Indenture Act; provided 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, a suit by a Holder pursuant to Section 408 hereof, or a suit by Holders of more than 10% in principal amount of the then Outstanding Notes. 

Section 415. Waiver of Usury, Stay or Extension Laws. 

The Company 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 the Company (to the extent that it may lawfully do so)
hereby expressly waives all benefit or advantage of any such law and covenants that it will not 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 FIVE 

The Trustee 
 Section 501. Certain
Duties and Responsibilities. 
  

	(a)	Except during the continuance of an Event of Default, 

  

	 	(1)	the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and


  

	 	(2)	in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee
and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same
to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). 


 

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


  
 28 









	(c)	No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that 


 

	 	(1)	this Subsection shall not be construed to limit the effect of Subsection (a) of this Section; 

  

	 	(2)	the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; 


 

	 	(3)	the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in principal amount of the Outstanding Notes,
determined as provided in Sections 101, 104 and 412, relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with
respect to the Notes; and 

  

	 	(4)	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. 


 

	(d)	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 502. Notice of Defaults.

such, and (ii) has a combined capital and surplus of at least $50,000,000; provided, however, that if the Trustee shall be a member of a bank holding company group, such bank holding company group shall have combined capital and surplus

 Section 510. 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 511. 
 The Trustee may resign at any time by giving
written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 511 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Notes. 
 The Trustee may be removed
at any time by Act of the Holders of a majority in principal amount of the Outstanding Notes, delivered to the Trustee and to the Company. 
 If at any
time: 
  

	 	(1)	the Trustee shall fail to comply with Section 508 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Note for at least six months, or 


 

	 	(2)	the Trustee shall cease to be eligible under Section 509 and shall fail to resign after written request therefor by the Company or by any such Holder, 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, or (B) subject to Section 414, any Holder who has been a bona fide Holder of a Note 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 and the appointment of a successor Trustee. 
 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, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees (it being understood that at any time there shall be only one
Trustee) and shall comply with the applicable requirements of Section 511. 
 If, within one year after such resignation, removal or incapability, or
the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Notes delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 511, become the successor Trustee with respect to the Notes and to that extent supersede the successor Trustee appointed by the Company.
If no successor Trustee with respect to the Notes shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 511, any Holder who has been a bona fide Holder of a Note for at least six
months or the Trustee at the 

  
 33 








 
expense of the Company 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
Notes. 
 The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders in
the manner provided in Section 106. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. 

Section 511. Acceptance of Appointment by Successor. 

In case of the appointment hereunder of a successor Trustee with respect to the Notes, every such successor Trustee so appointed shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. 

Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such
successor Trustee all such rights, powers and trusts referred to in this Section, 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 512. Merger, Conversion,
Consolidation or Succession to Business. 
 Any corporation into which the Trustee may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the
successor of the Trustee hereunder, provided such corporation 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. In case any
Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the
same effect as if such successor Trustee had itself authenticated such Notes. In the event any Notes shall not have been authenticated by such predecessor Trustee, any such successor Trustee may authenticate and deliver such Notes, in either its own
name or that of its predecessor Trustee, with the full force and effect which this Indenture provides for the certificate of authentication of the Trustee. 

  
 34 








 Section 513. Preferential Collection of Claims Against Company. 

If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of
the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor). 
 Section 514. Appointment of
Authenticating Agent. 
 The Trustee may appoint an Authenticating Agent or Agents with respect to the Notes which shall be authorized to act on behalf
of the Trustee to authenticate the Notes issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 206, and Notes 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 Notes 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 corporation 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 $50,000,000 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 corporation into which an Authenticating Agent may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating
Agent, shall continue to be an Authenticating Agent, provided such corporation 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 provide notice of such appointment to the Holders of the
Notes with respect to which such Authenticating Agent will serve, in the manner provided in Section 106. 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. 

  
 35 








 The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services
under this Section. 
 If an appointment is made pursuant to this Section, the Notes may have endorsed thereon, in addition to the Trustee’s
certificate of authentication, an alternative certificate of authentication in the following form: 
 This is one of the Notes referred to in the
within-mentioned Indenture.

(as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

time on each due date of the principal of or any premium or interest on the Notes, 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 the Notes 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 (or any other obligor upon the Notes) in the making of any payment in respect of the Notes, and 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 Notes. 
 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 Note 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 (including interest income accrued on said funds to
which the Company is otherwise entitled), or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note, as an unsecured general creditor, shall 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. 

Section 904. Statement by Officers as to Default. 

The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’
Certificate, stating whether or not to the best knowledge of the signers thereof the Company 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 shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. 

Section 905. Existence. 
 Subject to Article Seven,
the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and 

  
 42 








 
franchises; provided, however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors 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 of the Notes. 

Section 906. Maintenance of Properties. 
 The
Company will cause all properties used or useful in the conduct of its business to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs,
renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business and not
disadvantageous in any material respect to the Holders of the Notes. 
 Section 907. Payment of Taxes and Other Claims. 

The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (i) all taxes, assessments and governmental
charges levied or imposed upon the Company or upon the income, profits or property of the Company, and (ii) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a Lien upon the property of the Company;
provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate
proceedings or if such failure to pay or discharge could not reasonably be expected to have a material adverse effect on the business, operations, affairs, financial condition, assets or properties of the Company and its subsidiaries taken as a
whole or on the ability of the Company to pay the Notes in accordance with their terms. 
 Section 908. Restrictions on Liens. 

 

	 	(1)	The Company will not, at any time during which any Notes are Outstanding, issue, assume or guarantee any debt for money borrowed (hereinafter referred to as “Debt”) secured by any Lien upon any property
or asset of the Company (whether such property or asset is now owned or hereafter acquired), without in any such case effectively securing, prior to or concurrently with the issuance, assumption or guarantee of any such Debt, the Notes (together
with, if the Company shall so determine, any other indebtedness of or guarantee by the Company ranking equally with the Notes and then existing or thereafter created) equally and ratably with (or, at the Company’s option, prior to) such Debt,
provided, however, that the foregoing restrictions shall not apply to or prevent the creation of: 

  

	 	(A)	 Liens on any property acquired, constructed or improved by the Company after the Issue Date that are created or assumed contemporaneously with,




  
 43 









	 	
or within 120 days after, such acquisition or completion of the construction or improvement, or within six months thereafter pursuant to a firm commitment for financing arranged with a lender or
investor within such 120-day period, to secure or provide for the payment of all or any part of the purchase price of such property or the cost of such construction or improvement incurred after the Issue
Date, or, in addition to Liens contemplated by clauses (1)(B) and (1)(C) below, Liens on any property existing at the time of acquisition thereof, provided that the Liens do not apply to any property theretofore owned by the Company
other than, in the case of any such construction or improvement, any theretofore unimproved property on which the property so constructed or the improvement is located; 


 

	 	(B)	existing Liens on any property or indebtedness of a Person that is merged with or into or consolidated with the Company; provided that the Liens shall not apply to any property theretofore owned by the Company;


  

	 	(C)	Liens in favor of the United States of America, any state or any foreign country or any department, agency or instrumentality or political subdivision of any such jurisdiction to secure partial, progress, advance or
other payment pursuant to any contract or statute or to secure any indebtedness incurred for the purpose of financing all or any part of the purchase price or cost of constructing or improving the property subject to such Liens, including, without
limitation, Liens to secure Debt of the pollution control or industrial revenue bond type; 

  

	 	(D)	Liens on current assets of the Company to secure loans which mature within 12 months from the creation thereof and which are made in the ordinary course of business; 


 

	 	(E)	Liens on any property (including any natural gas, oil or other mineral property) of the Company to secure all or part of the cost of exploration or drilling for or development of oil or gas reserves or laying a pipeline
or to secure Debt incurred to provide funds for any such purpose; 

  

	 	(F)	any Lien existing on the Issue Date; 

  

	 	(G)	Liens on moneys or government obligations deposited with a trustee or agent for holders of Debt to defease such Debt; and 

  

	 	(H)	Liens for the sole purposes of extending, renewing or replacing, in whole or in part, Liens securing Debt of the type referred to in the foregoing clauses (1)(A) through (1)(G), inclusive, or this
clause (1)(H); provided, however, that the principal amount of Debt so secured at the time of such extension, renewal or replacement may not be increased, and that such extension, renewal or replacement is limited to all or
part of the property or indebtedness which secured the Lien so extended, renewed or replaced (plus improvements on such property). 


  
 44 









	 	(2)	The provisions of Section 908(1) shall not apply to the issuance, assumption or guarantee by the Company of Debt secured by a Lien which would otherwise be subject to such restrictions up to an aggregate amount
that, together with all other Indebtedness of the Company (other than Debt secured by Liens permitted by Section 908(1)) that would otherwise be subject to such restrictions and the Value of all Sale and
Lease-back Transactions in existence at such time (other than any Sale and Lease-back Transaction that, if such Sale and
Lease-back Transaction had been a Lien, would have been permitted by Section 908(1)(A) and other than Sale and Lease-back Transactions as to which application of
amounts have been made in accordance with Section 909(2)), does not at the time the Company issues, assumes or guarantees Debt secured by such Lien exceed 10% of Total Capitalization. 


 

	 	(3)	“Value” means, with respect to a Sale and Lease-back Transaction, as at any time, the amount equal to the greater of: 


 

	 	(A)	the net proceeds from the sale or transfer of the property leased pursuant to such Sale and Lease-back Transaction; and 


 

	 	(B)	the fair value, in the opinion of the Board of Directors of the Company, of such property at the time of entering into such Sale and Lease-back Transaction, 


in either case divided first by the number of full years of the term of the lease and then multiplied by the number of full years of such term
remaining at the time of determination, without regard to any renewal or extension options contained in the lease. 
  

	 	(4)	If at any time the Company shall issue, assume or guarantee any Debt secured by any Lien and if Section 908(1) requires that the Notes be secured equally and ratably with such Debt, the Company will promptly
deliver to the Trustee: 

  

	 	(A)	an Officers’ Certificate stating that the covenant of the Company contained in Section 908(1) has been complied with; and 

  


	 	(B)	an Opinion of Counsel to the effect that such covenant has been complied with, and that any instrument executed by the Company in the performance of such covenant complies with such covenant. 


 

	 	(5)	 In the event that the Company shall hereafter secure the Notes equally and ratably with (or prior to) any other Debt or obligation pursuant to the
provisions of this Section 908, the Trustee is hereby authorized to enter into an indenture or agreement supplemental hereto and to take such action, if any, as it may deem advisable to enable it to enforce effectively the rights of the holders
so secured, equally and ratably with such Debt and other obligations; provided, however,  



  
 45 









	 	
that if such indenture or agreement affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, the Trustee may in its discretion, but shall not be
obligated to, enter into such supplemental indenture or agreement. 

 Section 909. Restrictions on Sale and Lease-back Transactions. 
 The Company will not enter into any direct or indirect arrangement with any Person
providing for the lease to the Company of any property of the Company (except for temporary leases for a term, including any renewal thereof, of not more than three years), which property has been or is to be sold or transferred by the Company to
such Person or to any other Person by whom funds have been or are to be advanced on the security of such property (a “Sale and Lease-back Transaction”) unless the proceeds of
such sale are at least equal to the fair value of such property being sold and leased-back and either: 
  

	 	(1)	the Company would be entitled, pursuant to the provisions of Section 908(1)(A) or Section 908(2) to incur Debt secured by a Lien on such property without equally and ratably securing the Notes; or


  

	 	(2)	within 180 days of the effective date of the Sale and Lease-back Transaction, the Company applies, or covenants that it will apply, an amount not less than the fair value of such
property to one or more of: 

  

	 	(A)	the payment or other retirement of Funded Debt incurred or assumed by the Company which ranks senior to or pari passu with the Notes (other than Funded Debt owned by the Company), or 


 

	 	(B)	the purchase of property of the Company at not more than its fair value (other than the property involved in such sale).

The Trustee shall not be responsible for the computation of the Redemption Price with respect to any redemption occurring prior to April 1, 2043. The
Quotation Agent shall compute such Redemption Price. The Company shall promptly notify the Trustee of such Redemption Price and the computation thereof. 

  
 46 








 Section 1002. Election to Redeem; Notice to Trustee. 

The election of the Company to redeem any Notes shall be evidenced by a Board Resolution. In case of any redemption at the election of the Company of less

to be redeemed. 
 Section 1003. Selection by Trustee of Notes to Be Redeemed. 

If less than all the Notes are to be redeemed, the particular Notes to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the
Trustee, from the Outstanding Notes not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions (equal to the minimum authorized denomination
for the Notes or any integral multiple thereof) of the principal amount of the Notes of a denomination larger than the minimum authorized denomination for the Notes. 

The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Notes selected for partial redemption,
the principal amount thereof to be redeemed. 
 For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the
redemption of Notes shall relate, in the case of any Notes redeemed or to be redeemed only in part, to the portion of the principal amount of such Notes which has been or is to be redeemed. 

If the Notes are represented by Global Notes, the beneficial interests therein shall be selected by the Depository in accordance with its customary
procedures. 
 Section 1004. Notice of Redemption.

	 	(3)	if less than all the Outstanding Notes are to be redeemed, the identification (and, in the case of partial redemption of any Notes, the principal amounts) of the particular Notes to be redeemed, 


 

	 	(4)	that on the Redemption Date the Redemption Price will become due and payable upon each such Note to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date, 


  
 47 









	 	(5)	the place or places where such Notes are to be surrendered for payment of the Redemption Price, and 

  

	 	(6)	the CUSIP numbers of the Notes to be redeemed. 

 Notice of redemption of the Notes to be redeemed at the

Section 1005. Deposit of Redemption Price. 
 On or
before 10:00 a.m. New York 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 903) an amount
of money sufficient to pay the Redemption Price of all the Notes which are to be redeemed on that date. 
 Section 1006. Notes Payable on Redemption
Date. 
 Notice of redemption having been given as aforesaid, the Notes so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price, and from and after such date (unless the Company shall default in the payment of the Redemption Price) such Notes shall cease to bear interest and, except as provided below, shall be void. Upon surrender of any such Note for
redemption in accordance with said notice, such Note shall be paid by the Company at the Redemption Price; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the
Holders of such Notes, or one or more Predecessor Notes, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 207. 

If any Note 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 Note. 
 Section 1007. Notes Redeemed in Part. 

Any Note which is to be redeemed only in part shall be surrendered at the 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, and the Trustee shall, upon
receipt of an Authentication Order, authenticate and deliver to the Holder of such Note without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange
for the unredeemed portion of the principal of the Note so surrendered.

 ARTICLE ELEVEN 

Defeasance and Covenant Defeasance 

Section 1101. Company’s Option to Effect Defeasance or Covenant Defeasance. 

The Company may elect, at its option by Board Resolution at any time, to have either Section 1102 or Section 1103 applied to the Outstanding Notes
upon compliance with the conditions set forth below in this Article Eleven. 
 Section 1102. Defeasance and Discharge. 

Upon the Company’s exercise of the option provided in Section 1101 to have this Section 1102 applied to the Outstanding Notes, the Company
shall be deemed to have been discharged from its obligations with respect to the Outstanding Notes as provided in this Section on and after the date the conditions set forth in Section 1104 are satisfied (hereinafter called
“Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the Outstanding Notes and to have satisfied all its other obligations under
the Notes and this Indenture (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 the Notes to receive, solely from the trust fund described in Section 1104 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Notes when payments are
due, (2) the Company’s obligations with respect to the Notes under Sections 204, 205, 206, 902 and 903, (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article Eleven. Subject to
compliance with this Article Eleven, the Company may exercise its option provided in Section 1101 to have this Section 1102 applied to the Outstanding Notes notwithstanding the prior exercise of its option provided in Section 1101 to
have Section 1103 applied to the Outstanding Notes. 
 Section 1103. Covenant Defeasance. 

Upon the Company’s exercise of the option provided in Section 1101 to have this Section 1103 applied to the Outstanding Notes, (i) the
Company shall be released from its obligations under Sections 905, 906, 907, 908, 909 and Clauses 2 and 3 of Section 701, and (2) the occurrence of any event specified in Sections 401(3) (with respect to Section 905, 906, 907, 908,
909 or Clauses 2 or 3 of Section 701) and 401(4) shall be deemed not to be or result in an Event of Default on and after the date the conditions set forth in Section 1104 are satisfied (hereinafter called “Covenant
Defeasance”). For this purpose, such Covenant Defeasance means that the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section (to the extent so
specified in the case of Section 401(3)), whether directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such Section to any other provision herein or in any other document,
but the remainder of this Indenture and the Notes shall be unaffected thereby. 

  
 49 








 Section 1104. Conditions to Defeasance or Covenant Defeasance. 

The following shall be the conditions to application of either Section 1102 or Section 1103 to the Outstanding Notes: 

 

	 	(1)	The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee that satisfies the requirements contemplated by Section 509 and agrees to comply with the provisions of
this Article Eleven 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 the Outstanding Notes, (A) money in an
amount, or (B) U.S. Government Obligations that 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, 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 the
Notes on the respective Stated Maturities, in accordance with the terms of this Indenture and the Notes. Unless such deposit consists solely of money, the Company shall provide an opinion of a nationally recognized firm of independent public
accountants expressed in a written certification delivered to the Trustee to the effect that such deposit is sufficient to pay and discharge the principal of and any premium and interest on the Notes on the respective Stated Maturities, in
accordance with the terms of this Indenture and the Notes. As used herein, “U.S. Government Obligation” means (x) any security that 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 of 1933, as amended) as custodian with respect to any U.S. Government Obligation specified in Clause (x) and held by such custodian for the account of the holder of such depositary receipt,
or with respect to any specific payment of principal of or interest on any such U.S. Government Obligation, 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 case of an election under Section 1102, 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 Issue Date, 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 



  
 50 









	 	
shall confirm that, the Holders of the Outstanding Notes 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 the Notes 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 case of an election under Section 1103, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the Outstanding Notes 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 the Notes 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 the Notes, if then listed on any securities exchange, will not be delisted as a result of such deposit. 


 

	 	(5)	No Event of Default or event that (after notice or lapse of time or both) would become an Event of Default shall have occurred and be continuing at the time of such deposit or, with regard to any Event of Default or any
such event specified in Sections 401(5) and (6), at any time on or prior to the 90th day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 90th 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 Notes are in default within the meaning of such Act).


  

	 	(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 is a party or by which it is bound.


  

	 	(8)	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. 

  

	 	(9)	Such Defeasance or Covenant Defeasance shall not result in the trust arising from such deposit constituting an investment company within the meaning of the Investment Company Act of 1940, as amended, unless such trust
shall be qualified under such Act or exempt from regulation thereunder. 

 Section 1105. Deposited Money and U.S. Government
Obligations to be Held in Trust; Other Miscellaneous Provisions. 
 Subject to the provisions of the last paragraph of Section 903, 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 1106, the Trustee and any such other


  
 51 








 
trustee are referred to collectively as the “Trustee”) pursuant to Section 1104 in respect of the Notes shall be held in trust and applied by the Trustee, in accordance with
the provisions of the Notes 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 the Notes, 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 1104 or the principal and interest received in respect thereof other than any such tax, fee or other charge that by law is for the account of the Holders of the Outstanding Notes. 

Anything in this Article Eleven 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 1104 with respect to the Notes that, 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 that would then be required to be deposited to effect an equivalent Defeasance or Covenant Defeasance with respect to the Notes. 

Section 1106. Reinstatement. 
 If the Trustee or the
Paying Agent is unable to apply any money in accordance with this Article Eleven with respect to the Notes by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application,
then the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article Eleven with respect to the Notes until such time as the Trustee or Paying Agent is
permitted to apply all money held in trust pursuant to Section 1105 with respect to the Notes in accordance with this Article Eleven; provided, however, that if the Company makes any payment of principal of or any premium or interest on
any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of the Notes to receive such payment from the money so held in trust. 

This instrument 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 one and the same instrument.

30-day months. In the event that any date on which interest is payable on this Note is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day that is a
Business Day (and without any interest or other payment in respect of such delay). The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose
name this Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest, which shall be the March 15 or September 15 (whether or not a Business Day), as the case may be, next
preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and may, upon election by the Company following notice to the Trustee,
be paid to the Person in whose name this Note (or one or more Predecessor Notes) 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, by giving notice to Holders of


  
 A-1 








 
Notes not less than 10 days prior to such Special Record Date and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment or as otherwise specified in the
Indenture. 
 Payment of the principal of and interest on this Note will be made at the office of the Trustee, initially at 2 N. LaSalle
Street, Suite 1020, Chicago, Illinois 60602, 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 Note Register on the Regular Record Date, except that in the event that this Note is registered in the name of
the nominee of a clearing agency, interest payments will be made in the form of immediately available funds. 
 Reference is hereby made to
the additional provisions of this Note set forth on the reverse hereof, which additional provisions shall for all purposes have the same effect as if set forth on the face hereof. 

Unless the certificate of authentication below has been executed by the Trustee referred to on the reverse hereof, this Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any purpose. 
 IN WITNESS WHEREOF, the Company has caused this
instrument to be duly executed.

 [FORM OF REVERSE SIDE OF THE NOTE] 

This Note is one of a duly authorized issue of obligations of the Company (herein called the “Notes”), issued and to be
issued under an Indenture (the “Indenture”) dated as of October 4, 2013 between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee”, which term includes any
successor trustee under the Indenture). Reference to the Indenture is hereby made for a statement of the respective rights, limitations of rights, duties and immunities of the Company, the Trustee and the Holders of the Notes and of the terms upon
which the Notes are, and are to be, authenticated and delivered. Subject to the terms of the Indenture, the Company shall be entitled to issue Additional Notes pursuant to Section 201 of the Indenture. 

All or a portion of the Notes (including any Additional Notes) are subject to redemption at the option of the Company upon not less than 30
days’ and not more than 60 days’ notice by mail (i) at any time prior to April 1, 2043, at a Redemption Price equal to the greater of (a) 100% of the principal amount of the Notes to be redeemed on the Redemption Date
specified in the notice of redemption, plus accrued and unpaid interest on such Notes up to, but excluding, such Redemption Date, or (b) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of
principal and interest on the Notes to be redeemed on such Redemption Date (not including any portion of payments of interest accrued to such Redemption Date) discounted to such Redemption Date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 20 basis
points, plus accrued and unpaid interest thereon up to, but excluding such Redemption Date, or (ii) at any time on or after April 1, 2043 (six months prior to the maturity date of the Notes), 100% of the principal amount of the Notes to be
redeemed on the Redemption Date specified in the notice of redemption, plus accrued and unpaid interest on such Notes up to, but excluding, such Redemption Date. 

In the event of redemption of this Note in part only, a new Note or Notes for the unredeemed portion hereof will be issued in the name of the
Holder hereof upon cancellation of this Note. 
 In certain circumstances described in the Indenture, the Company’s obligations in
respect of the Notes or in respect of certain covenants made for the benefit of the Notes may be discharged prior to payment upon depositing with the Trustee cash and/or U.S. Government Obligations in the required amount and upon compliance with
certain other provisions of the Indenture. 
 If an Event of Default with respect to Notes occurs and is continuing, the principal of the
Notes may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture contains provisions
permitting the Company and the Trustee, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes affected at the time outstanding to execute supplemental indentures for the purpose of adding any
provisions to, changing in any manner, or eliminating any of the provisions of the Indenture, or for the purpose of modifying in any manner the rights of the Holders of the Notes; provided, 


  
 A-3 








 
however, that no supplemental indenture shall (i) change the stated maturity of the principal or interest on any Note, (ii) reduce the principal amount of or the interest
or premium payable on any Note, (iii) change the currency in which any Note is payable, (iv) impair the right of any Holder of any Note to bring suit to enforce any payment, (v) reduce the percentage of registered Holders of Notes,
the Holders of which are required to consent to any amendment, modification or waiver or (vi) modify certain of the provisions in the indenture relating to supplemental indentures, in each case, without the consent of the registered Holder of
each Note affected thereby. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Notes outstanding and affected thereby, on behalf of all of the Holders of the Notes, to waive any past
default in the performance of any of the covenants contained in the Indenture, or established pursuant to the Indenture, and its consequences, except a default (i) in the payment of the principal of, premium or interest on any of the Notes, or
(ii) in respect of a provision contained in the Indenture which cannot be modified or amended without the consent of the Holders of each outstanding Note affected thereby. Any consent or waiver by the registered Holder of this Note (unless
revoked as provided in the Indenture) shall be conclusive and binding upon that Holder and upon all future Holders and owners of this Note and of any Note issued in exchange herefor or in place hereof (whether by registration of transfer or
otherwise), irrespective of whether or not any notation of the consent or waiver is made upon this Note. 
 In certain limited
circumstances, the Indenture may be amended, and the rights and obligations of the Company and the rights of the Holders may be modified, at any time by the Company and the Trustee without notice to or consent of the Holders. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of and interest on this Note at the times, places and rate, and in the coin or currency, described herein. 

As provided in the Indenture and subject to certain limitations set forth therein, the transfer of this Note is registrable in the Note
Register upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Note are payable, if duly endorsed by, or if accompanied by a written instrument of
transfer (in a form that is satisfactory to the Company and the Note Registrar) duly executed by, the Holder hereof or his attorney duly authorized in writing; thereupon one or more new Notes, of authorized denominations and like aggregate principal
amount, will be issued to the designated transferee or transferees. The Notes are issuable only in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture
and subject to certain limitations therein set forth, the Notes are exchangeable for other Notes, as requested by the Holder surrendering the same. No service charge shall be made for any such registration of transfer or exchange, but the Company
may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith to the extent provided in the Indenture. 

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and neither the Company, the Trustee nor any agent shall be affected by notice to the contrary. 

  
 A-4 








 No recourse shall be had for the payment of the principal of or the interest on this Note, or for
any claim based hereon or on the Indenture, against any incorporator, shareholder, officer or director, past, present or future, as such, of the Company or of any predecessor or successor Corporation, under any rule of law, statute or constitution
or by the enforcement of any assessment or otherwise, all such liability being released by the Holder by accepting this Note and being likewise waived and released by the terms of the Indenture. 

All capitalized terms used in this Note without definitions that are defined in the Indenture shall have the meanings assigned to them in the
Indenture.
