assessments, water rates or similar charges. In the case of any lease which is terminable by the lessee upon payment of a penalty, such net amount of rent shall also include the amount of such penalty, but no rent shall be considered as required to
be paid under such lease subsequent to the first date upon which it may be so terminated.

without limitation, any agreement to give or grant a Lien or any lease, conditional sale or other title retention agreement having substantially the same
economic effect as any of the foregoing) upon or with respect to any property of any kind. A Person shall be deemed to own subject to a Lien any Property which such Person has acquired or holds subject to the interest of a vendor or lessor under any
conditional sale agreement, capital lease or other title retention agreement. 
 “Make-Whole Amount” with respect to a Security
means an amount equal to the excess, if any, of (i) the present value of the remaining interest, premium and principal payments due on such Security (excluding any portion of such payments of interest accrued as of the Redemption Date),
computed using a discount rate equal to the Treasury Rate plus 15 basis points, over (ii) the outstanding principal amount of such Security. As used herein, “Treasury Rate” is defined as the yield to maturity (calculated on a
semi-annual bond equivalent basis) at the time of the computation of United States Treasury securities with a constant maturity (as compiled by and published in the most recent Federal Reserve Statistical Release H.15 (510), which has become
publicly available at least two Business Days prior to the date of the redemption notice or, if such Statistical Release is no longer published, any publicly available source of similar market data) most nearly equal to the then remaining maturity
of the Security; provided, however, that if the Make-Whole Average Life of such Security is not equal to the constant maturity of the United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be
obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the Make-Whole Average Life of such Security is
less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used. As used herein, “Make-Whole Average Life” means the number of years (calculated to

redemption or purchase or otherwise. 
 “Non-Recourse Debt” means Debt or that portion of Debt of the Company or a Subsidiary
incurred in connection with the acquisition by the Company or a Subsidiary of any Property and as to which (a) the holders of such Debt agree that they will look solely to the Property so acquired and securing such Debt for payment on or in
respect of such Debt and (b) no default with respect to such Debt would permit (after notice, passage of time or both), according to the terms thereof, any holder of any other Debt of the Company or its Subsidiaries to declare a default on such
other Debt or cause the payment thereof to be accelerated or payable prior to its Stated Maturity. 
 “Officer” means, with respect
to any Person, the Chairman of the Board, the President, any Vice President, the Chief Financial Officer or the Treasurer of such Person.

 “Original Issue Discount Security” means any Security which provides for an amount less than the principal amount thereof to be due and payable upon a declaration of acceleration of maturity thereof pursuant
to Section 4.2. 
 “Outstanding,” when used with respect to any series of Securities, means, as of the date of determination,
all Securities of that series theretofore authenticated and delivered under this Indenture, except: 
 (a) Securities of that
series theretofore canceled by the Trustee or delivered to the Trustee for cancellation; 
 (b) Securities of that series, for
whose payment or redemption money in the necessary amount has been theretofore deposited with the Trustee or any Paying Agent (other than the Company) in trust or set aside and segregated in trust by the Company (if the Company shall act as its own
Paying Agent) for the Holders of such Securities; provided that, if such Securities are to be redeemed, notice of such redemption has been duly given pursuant to this Indenture or provision therefor satisfactory to the Trustee has been made;

 (c) Securities of that series, except to the extent provided in Sections 11.2 and 11.3, with respect to which the Company
has effected defeasance and/or covenant defeasance as provided in Article XI; and 
 (d) Securities of that series which have
been paid pursuant to Section 2.11 or in exchange for or in lieu of which other Securities have been authenticated and delivered pursuant to this Indenture, other than any such Securities in respect of which there shall have been presented to
the Trustee proof satisfactory to it that such Securities are held by a bona fide purchaser in whose hands the Securities are valid obligations of the Company; 
 provided, however, that in determining whether the Holders of the requisite principal amount of Outstanding Securities have given any request, demand, authorization, direction, consent, notice or waiver hereunder, and for the
purpose of making the calculations required by TIA Section 313, Securities owned by the Company or any other obligor upon the Securities or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be
Outstanding, except that, in determining whether the Trustee shall be protected in making such calculation or in relying upon any such request, demand, authorization, direction, consent, notice or waiver, only Securities which a Responsible Officer
of the Trustee actually knows to be so owned shall 

  

 6 








 
be so disregarded. Securities so owned which have been pledged in good faith may be regarded as Outstanding if the pledgee establishes to the satisfaction of
the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not the Company or any other obligor upon the Securities or any Affiliate of the Company or such other obligor. In determining whether the Holders
of the requisite principal amount of Outstanding Securities have given any request, demand, authorization, direction, notice, consent or waiver hereunder, the principal amount of an Original Issue Discount Security that shall be deemed to be
Outstanding for such purposes shall be the amount of the principal thereof that would be due and payable as of the date of such determination upon a declaration of acceleration of the maturity thereof pursuant to Section 4.2. In determining
whether the Holders of the requisite principal amount of the Outstanding Securities of any series have given any request, demand, authorization, direction, notice, consent or waiver hereunder, the principal amount of a Security denominated in one or
more foreign currencies or currency units that shall be deemed to be Outstanding for such purposes shall be the U.S. dollar equivalent, determined in the manner provided as contemplated by Section 2.2 on the date of original issuance of such
Security, of the principal amount (or, in the case of any Original Issue Discount Security, the U.S. Dollar equivalent on the date of original issuance of such Security of the amount determined as provided in the preceding sentence) of such
Security. 
 “Pari Passu Debt” means any Funded Debt of the Company, whether outstanding on the date of this Indenture or

 The Securities shall be executed on behalf of the Company by its Chairman, its President or one of its Vice Presidents. The Company’s corporate seal
may be affixed, imprinted or reproduced (which may be in facsimile form) on the Securities. The signature of any of these officers on the Securities may be manual or facsimile signatures of the present or any future such authorized officer and may
be imprinted or otherwise reproduced on the Securities. 
 Securities bearing the manual or facsimile signatures of individuals who were at
any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the
date of such Securities. 
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver
Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with such Company Order shall authenticate and
deliver such Securities as provided in this Indenture. Prior to authentication and delivery of such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to
receive, and shall be fully protected in relying upon:

issuance of any series of Securities;

 (2) that the Company has the corporate power to issue such Securities, and such Securities have been duly authorized, executed and
delivered by the Company and, assuming due authentication and delivery by the Trustee, constitute valid and legally binding obligations of the Company enforceable in accordance with their terms (subject to bankruptcy, reorganization, insolvency and
other laws and legal principles affecting creditors’ rights and to general principles of equity), and entitled to the benefits of this Indenture; and 
 (3) that the execution and delivery by the Company of such Securities does not violate any applicable law or legal requirement known to such counsel. 
 Each Security shall be dated the date of its authentication.

in good faith shall determine that such action would expose the Trustee to personal liability to existing Holders. 
 The Trustee may appoint
an authenticating agent reasonably acceptable to the Company to authenticate Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this
Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Securities Registrar, Paying Agent or agent for service of notices and demands. 
 No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized signatory, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that
such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. 
  

 16

executed in the name of the successor Person with such changes in phraseology and form as may be appropriate, but otherwise in substance of like tenor as the Securities surrendered for such exchange and of like principal amount; and the Trustee,
upon Company Request of the successor Person, shall authenticate and deliver Securities as specified in such request for the purpose of such exchange. If Securities of any series shall at any time be authenticated and delivered in any new name of a
successor Person pursuant to this Section in exchange or substitution for or upon registration of transfer of any Securities, such successor Person, at the option of the Holders of such series but without expense to them, shall provide for the
exchange of all Securities of the series at the time Outstanding for Securities of the series authenticated and delivered in such new name.

co-registrar or transfer agent.

 17 








 
shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the
Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, on or interest on Securities and shall notify the Trustee of any default by the Company in making any such payment. If the Company or a Subsidiary acts as
Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the
Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee.

Security.

 Pending the preparation of Definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities, which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the Definitive Securities in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as conclusively evidenced by their execution of such Securities. 
 If temporary Securities of any series are issued, the Company will cause Definitive Securities of such series to be prepared without unreasonable delay.
After the preparation of Definitive Securities of such series, the temporary Securities of such series shall be exchangeable for Definitive Securities of such series upon surrender of the temporary Securities at the office or agency of the Company
designated for such purpose pursuant to Section 9.2, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver
in exchange therefor a like principal amount of Definitive Securities of the same series of authorized denominations. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this
Indenture as Definitive Securities of such series. 
 SECTION 2.9 Transfer and Exchange. 
 (a) Transfer and Exchange of Definitive Securities. When Definitive Securities of any series are presented to the Securities Registrar with the
request: 
 (i) to register the transfer of such Definitive Securities, or 
  

 18 








 (ii) to exchange such Definitive Securities for an equal principal amount of Definitive
Securities of the same series of other authorized denominations, 
 the Securities Registrar shall register the transfer or make the exchange as requested if
its requirements for such transactions are met; provided, however, that the Definitive Securities presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in
form satisfactory to the Securities Registrar duly executed by the Holder thereof or by his attorney, duly authorized in writing. 
 (b)
Restriction on Transfer of a Definitive Security for a Beneficial Interest in a Global Security. A Definitive Security of a series may not be exchanged for a beneficial interest in a Global Security of the same series except upon satisfaction

directing the Trustee to make, or directing the Security Custodian to make, an endorsement on the Global Security of the same series to reflect an increase in the aggregate principal amount of the Securities represented by such Global Security, then
the Trustee shall cancel such Definitive Security in accordance with Section 2.14 and cause, or direct the Security Custodian to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Security
Custodian, the aggregate principal amount of Securities represented by such Global Security to be increased accordingly. If no Global Securities of such series are then outstanding, the Company shall issue and the Trustee shall authenticate a new
Global Security of the same series in the appropriate principal amount. 
 (c) Transfer and Exchange of Global Securities. The Company
initially appoints The Depository Trust Company to act as Depository with respect to each Global Security. The transfer and exchange of Global Securities of any series or beneficial interests therein shall be effected through the Depositary, in
accordance with this Indenture and the procedures of the Depositary therefor. 
 (d) Transfer of a Beneficial Interest in a Global
Security for a Definitive Security. 
 (i) Any Person having a beneficial interest in a Global Security of any series may
upon request to the Trustee exchange such beneficial interest for a Definitive Security of the same series. Upon receipt by the Trustee of written instructions, or such other form of instructions as is customary for the Depositary, from the
Depositary or its nominee on behalf of any Person having a beneficial interest in a Global Security of a series. The Trustee or the Security Custodian, at the direction of the Trustee, shall, in accordance with the standing instructions and
procedures existing between the Depositary and the Security Custodian, cause the aggregate principal amount of Global Securities of such series to be reduced accordingly and, following such reduction, the Company shall execute and the Trustee shall
authenticate and deliver to the transferee a Definitive Security of the same series in the appropriate principal amount. 
  

 19 








 (ii) Definitive Securities of a series issued in exchange for a beneficial interest in a
Global Security of the same series pursuant to this Section 2.9(d) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The Trustee shall deliver such Definitive Securities to the Persons in whose names such Securities are so registered. 
 (e) Restrictions on Transfer and Exchange of Global Securities. Notwithstanding any other provisions of this Indenture (other than the provisions set forth in subsection (f) of this Section 2.9), any Global Security may not
be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a
nominee of such successor Depositary. Each Security certificate evidencing Global Securities shall bear the paragraph referred to in footnote 1 in the form of Security attached hereto as Exhibit A. 
 (f) Authentication of Definitive Securities in Absence of Depositary. If at any time: 
 (i) the Depositary for Securities of a series notifies the Company that the Depositary is unwilling or unable to continue as Depositary
for such Global Securities of such series and a successor Depositary for such Global Securities is not appointed by the Company within 90 days after delivery of such notice; 
 (ii) an Event of Default with respect to Securities of a series then Outstanding has occurred and is continuing and the Security Registrar

 (iii) the Company, at its sole discretion, notifies the Trustee in writing that it elects to cause the issuance of
Definitive Securities of a Series under this Indenture; 
 then the Company will execute, and the Trustee will authenticate and deliver, Definitive
Securities of such series in an aggregate principal amount equal to the principal amount of the Global Securities of such series, in exchange for such Global Securities and registered in such names as the Depositary shall instruct the Trustee or the
Company in writing. 
 (g) Cancellation and/or Adjustment of Global Security. At such time as all beneficial interests in a Global
Security of a series have either been exchanged for Definitive Securities of such series, redeemed, repurchased or canceled, such Global Security shall be returned to or retained and cancelled by the Trustee. At any time prior to such cancellation,
if any beneficial interest in such Global Security is exchanged for Definitive Securities of such series, redeemed, repurchased or cancelled, the principal amount of Securities represented by such Global Security shall be reduced and an endorsement
shall be made on such Global Security, by the Trustee or the Security Custodian, at the direction of the Trustee to reflect such reduction.

 (h) General Provisions with respect to Transfer and Exchanges. 
 (i) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Definitive Securities
and Global Securities at the Registrar’s request. 
 (ii) No service charge shall be made to a Holder for any
registration of transfer or exchange or redemption of Securities (except as otherwise expressly permitted herein), but the Company or the Security Registrar may require payment of a sum sufficient to cover any transfer tax or similar governmental
charge payable in connection therewith (other than such transfer tax or similar governmental charge payable upon exchanges pursuant to the last paragraph of Section 2.4 or Sections 2.8, 8.6 or 10.7). 
 (iii) The Trustee shall authenticate Definitive Securities and Global Securities in accordance with the provisions of Section 2.4.

 (iv) Notwithstanding any other provisions of this Indenture to the contrary, the Company shall not be required to register
the transfer or exchange of a Security between the record date and the next succeeding Interest Payment Date. 
 (v) Neither
the Company nor the Trustee will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, Securities of any series by the Depositary, or for maintaining, supervising or reviewing any records of
the Depositary relating to such Securities. Neither the Company nor the Trustee shall be liable for any delay by the related Global Security Holder or the Depositary in identifying the beneficial owners of the related Securities, and the Company and
the Trustee may conclusively rely on, and shall be protected in relying on, instructions from such Global Security Holder or the Depositary for all purposes (including with respect to the registration and delivery, and the respective principal
amounts, of the Securities of any series to be issued). 
 (vi) Neither the Trustee, the Security Registrar nor the Company
shall be required (A) to issue, register the transfer of or exchange any Security of a series during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of Securities of such series selected for
redemption under Section 10.3 and ending at the close of business on the day of such mailing of the relevant notice of redemption, or (B) to register the transfer of or exchange any Security so selected for redemption in whole or in part,
except the unredeemed portion of any Security being redeemed in part. 
 (vii) All Securities issued upon any registration of
transfer or exchange of Securities shall be the valid obligations of the Company evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

 (viii) Each Holder of a Security of a series agrees to indemnify the Company and the Trustee against any liability that may
result from the transfer, exchange or assignment of such Holder’s Security in violation of any provision of this Indenture and/or applicable federal or state securities law. 
  

 21 








 SECTION 2.10 Additional Provisions for Global Securities. 
 (a) The Global Security of any series initially shall be registered in the name of the Depositary for such Global Security or the nominee of such
Depositary and be delivered to the Trustee as custodian for such Depositary. 
 (b) Members of, or participants in, the Depositary
(“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under any Global Security, and the Depositary may be treated by the
Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by the Depositary or shall impair, as between the Depositary and its Agent Members, the operation of customary practices governing the
exercise of the rights of a holder of any Security. 
 (c) The registered holder of the Global Security of any series may grant proxies and
otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action permitted by a Holder of Securities of such series. 
 SECTION 2.11 Mutilated, Destroyed, Lost and Stolen Securities. 
 If
(i) any mutilated Security is surrendered to the Trustee or (ii) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company and the Trustee
such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon
Company Order the Trustee shall authenticate and deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of the same series of like tenor and principal amount bearing a number
not contemporaneously outstanding. 
 In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and
payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 
 Upon the issuance of any new Security
under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected
therewith. 
  

 22 








 Every new Security issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen
Security shall constitute an original additional contractual obligation of the Company whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this
Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. 
 The provisions of this
Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
 SECTION 2.12 Payment of Interest; Interest Rights Preserved. 
 Interest on any Security 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 such Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose pursuant to Section 9.2.

 Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date
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 and (to the extent lawful) interest on such defaulted interest at the rate prescribed therefor in
such Security (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below: 
 (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective
Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of
Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in
respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited shall 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 given in the manner provided for in Section 13.5, 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 given, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of
business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). 
  

 23 








 (2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent
with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause,
such manner of payment shall be deemed practicable by the Trustee. 
 Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 
 SECTION 2.13 Persons Deemed Owners. 
 Prior to the due presentment of a Security for registration of transfer, the Company, the Securities Registrar, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security
is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium, if any, on) and (subject to Section 2.12) interest on such Security and for all other purposes whatsoever, whether or not such
Security be overdue, and none of the Company, the Security Registrar, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary. 
 SECTION 2.14 Cancellation. 
 All Securities surrendered for payment,
redemption, registration of transfer or exchange or for credit against any sinking fund shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time
deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee
in its customary manner. 
 SECTION 2.15 Computation of Interest. 
 Except as otherwise provided or contemplated by Section 2.1, interest on the Securities of each series shall be computed on the basis of a 360-day
year comprised of twelve 30-day months. 
 SECTION 2.16 CUSIP Numbers. 
 The Company in issuing the Securities of any series may use numbers assigned by the Committee on Uniform Securities Identification Procedures
(“CUSIP”) and corresponding 

  

 24 








 
International Securities Identification Numbers (“ISIN”) (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers
and corresponding ISINs (if then generally in use) in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the
Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers.
The Company will promptly notify the Trustee of any change in the CUSIP numbers or ISINs. 
 SECTION 2.17 Form of
Trustee’s Certificate of Authentication. 
 The Trustee’s certificate of authentication shall be in substantially the following
form:

written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on Outstanding Securities as of the end of such year and (ii) such other specific information relating to such original issue
discount as may then be relevant under the Internal Revenue Code of 1986, as amended from time to time.

acceleration of any Debt of the Company or any Subsidiary; provided that the aggregate principal amount of such Debt shall exceed $50,000,000;
provided further that if any such default is cured or waived or any such acceleration rescinded, or such Debt is repaid, within a period of 10 days from the continuation of such default beyond the applicable grace period or the occurrence of
such acceleration, as the case may be, such Event of Default under this Indenture and any consequential acceleration of such Securities shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree; or

declare all unpaid principal of (or, if Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified in the terms thereof), premium, if any, and accrued interest on all
Securities of that series to be due and payable immediately, upon which declaration all amounts payable in respect of such Securities shall be immediately due and payable. If an Event of Default specified in Section 4.1(f) or (g) occurs

 At any time after a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the
money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in aggregate principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind
such declaration and its consequences if:

 (i) all sums paid or advanced by the Trustee under this Indenture and the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, 
 (ii) all overdue interest on all Outstanding Securities of that series, 
 (iii) all unpaid principal of (and premium, if any, on) any Outstanding Securities of that series which has become due otherwise than by

 (iv) to
the extent that payment of such interest is lawful, interest upon overdue interest and overdue principal which has become due otherwise than by such declaration of acceleration (without duplication of any amount deposited pursuant to clauses
(ii) and (iii) above), at the rate or rates prescribed therefor in such Securities of that series; 
 (b) the rescission would not

 No such rescission shall affect any subsequent default or impair any right consequent thereon. 
 Notwithstanding the foregoing, in the event of a declaration of acceleration in respect of Securities of a series because of an Event of Default
specified in Section 4.1(e) shall have occurred and be continuing, such declaration of acceleration and any consequential acceleration shall be automatically rescinded if the Debt that is the subject of such Event of Default shall have been
repaid, or if the default relating to such Debt shall have been waived or cured and if such Debt were accelerated, then the holders thereof shall have rescinded their declaration of acceleration in respect of such Debt (provided, in each case, that
such repayment, waiver, cure or

acceleration), and written notice of such repayment, or cure or waiver and rescission, as the case may be, shall have been given to the Trustee by the Company and countersigned by the holders of such Debt or a trustee, fiduciary or agent for such
holders or other evidence satisfactory to the Trustee of such events is provided to the Trustee, within 30 days after such declaration of acceleration in respect of such Securities, and no other Event of Default has occurred during such 30-day
period which has not been cured or waived during such period, and so long as such rescission of the declaration of acceleration of such Securities does not conflict with any judgment or decree as certified to the Trustee by the Company. 

SECTION 4.3 Collection of Indebtedness and Suits for Enforcement by Trustee. 
 The Company covenants that if: 
 (i) default is made in the payment of any installment of interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or 
 (ii) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof, 
 the Company will, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest and interest on any overdue principal (and premium, if any) and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installment of interest, at the
rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel. 
 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name as
trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such
Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the Property of the Company or any other obligor upon such Securities, wherever situated. 
 If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in any provision of such Securities or this Indenture or in aid of the exercise of any power granted therein or herein, or to enforce any other proper remedy. 
  

 30

proceeding relative to the Company or any other obligor upon the Securities or the Property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities of any series shall then be
due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company or such other obligor for the payment of overdue principal, premium, if any, or interest) shall be
entitled and empowered, by intervention in such proceeding or otherwise: 
 (i) to file and prove a claim for the whole amount
of principal (and premium, if any) and interest owing and unpaid in respect of such Securities and to file such other papers or documents and take any other actions including participation as a full member of any creditor or other committee as may
be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial
proceeding, and 
 (ii) 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 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 the Trustee any amount due to 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 5.6. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the
rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 SECTION 4.5 Trustee May Enforce Claims Without Possession of Securities. 
 All rights of action

Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel,
be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

 SECTION 4.6 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 and, in the
case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

FIRST: To the payment of all amounts due the Trustee under Section 5.6; 
 SECOND: To the payment of the amounts then due and unpaid for principal of (and premium, if any, on) and interest on the Securities in respect of which

 THIRD: The balance, if any, to the Company. 
 SECTION 4.7 Limitation on Suits.

to obtain priority or preference over any other Holders of Securities of that series or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders of Securities of that
series.

the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

 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 thereunder, and all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

 SECTION 4.10 Rights and Remedies Cumulative. 
 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 2.11, no right or remedy herein conferred upon or reserved to the Trustee or to 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 4.11 Delay or Omission Not Waiver. 
 No delay or omission of the Trustee or of any Holder 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.

 Upon any such waiver, such Default or Event of Default shall cease to exist for
every purpose under this Indenture, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 
 SECTION 4.14 Waiver of Stay, Extension or Usury Laws. 
 The Company covenants (to the extent that
it may lawfully do so) that it will not at any time insist upon, plead or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension, or usury law or other law, which would prohibit or forgive the Company from paying all
or any portion of the principal of (premium, if any, on) and/or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and

 (f) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument,

 The Trustee shall not be required to advance, expend or risk its own funds or otherwise incur any financial liability in the performance of any of its

 SECTION 5.3 Trustee Not Responsible for Recitals or Issuance of Securities. 
 The recitals contained herein and in the Securities, except for the Trustee’s certificates of authentication, shall be taken as the statements of the

 SECTION 5.6 Compensation and Reimbursement. 
 The Company agrees: 
 (a) to pay to the Trustee from time to time such compensation as shall be agreed in writing from time to time between the Company and the Trustee for all

 The

Trustee under TIA Section 310(a)(1) and shall have a combined capital and surplus of at least $50,000,000. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of federal, state,
territorial or District of Columbia supervising or examining authority, then for the purposes of this Section 5.7, the combined capital and surplus of such corporation 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 the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this
Article. 
  

 38 








 SECTION 5.8 Conflicting Interests. 
 The Trustee shall comply with the provisions of Section 310(b) of the Trust Indenture Act. 
 SECTION 5.9 Resignation and Removal; Appointment of Successor. 
 (a) 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 5.10. 
 (b) The Trustee
may resign at any time with respect to Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 5.10 shall not have been delivered to the
Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities
of such series. 
 (c) The Trustee may be removed at any time with respect to Securities of any series by Act of Holders of a majority in
principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company. If the instrument of acceptance by a successor Trustee required by Section 5.10 shall not have been delivered to the Trustee within 30
days after the giving of such notice of removal, the Trustee being removed may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

 (d) If at any time: 
 (i) the Trustee shall fail to comply with the provisions of TIA Section 310(b) after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or 
 (ii) the Trustee shall cease to be eligible under Section 5.7 and shall fail to resign after written request therefor by the Company
or by any Holder who has been a bona fide Holder of a Security for at least six months, or 
 (iii) 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 TIA Section 315(e), any Holder who has been a bona fide Holder of a Security 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. 
  

 39 








 (e) If, with respect to the Securities of one or more series, 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 with respect to the Securities of such series. 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 Securities of such series delivered to the Company and
the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee with respect to the Securities of such series and supersede the successor Trustee appointed by the
Company. If no successor Trustee with respect to Securities of a series shall have been so appointed by the Company or Holders and accepted appointment in the manner required by Section 5.10, any Holder who has been a bona fide Holder of a
Security of the series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. Such
successorship may, but need not be, evidenced by a supplemental indenture. 
 (f) The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to the Holders of Securities of each series so affected in the manner provided for in Section 13.5. Each notice shall include the name of the successor Trustee and the address
of its Corporate Trust Office. 
 SECTION 5.10 Acceptance of Appointment by Successor. 
 Every successor Trustee appointed hereunder 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 request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of all amounts due it under Section 5.6, 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 to more fully and certainly vest in and confirm to such successor Trustee all such rights, powers and trusts. 
 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 5.11 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 of 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 

  

 40 








 
any Securities 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 Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities; and in case at that time any of the Securities shall not
have been authenticated, any successor Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such cases such certificates shall have the full force that is
provided anywhere in the Securities or in this Indenture; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Securities in the name of any predecessor Trustee shall apply
only to its successor or successors by merger, conversion or consolidation. 
 SECTION 5.12 Preferential Collection of Claims
Against Company. 
 If and when the Trustee shall be or become a creditor of the Company (or any other obligor under the Securities), 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. 
 ARTICLE VI 
 HOLDERS’ LISTS AND REPORTS BY TRUSTEE 
 SECTION 6.1 Disclosure of Names and Addresses of Holders. 
 Every Holder of Securities, by receiving and holding the same, agrees with the Company, the Security Registrar and the Trustee that none of the Company, the Security Registrar or the Trustee, or any agent of any of
them, shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the Holders in accordance with TIA Section 312, regardless of the source from which such information was derived, and that the
Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under TIA Section 312(b). 
 SECTION 6.2 Reports By Trustee. 
 Within 60 days after May 15 of each year commencing with
May 15, 2008, the Trustee shall transmit by mail to the Holders, as their names and addresses appear in the Security Register, a brief report dated as of such May 15 in accordance with and to the extent required under TIA
Section 313(a). The Trustee shall also comply with TIA Sections 313(b) and 313(c). 
 The Company shall promptly notify the Trustee
in writing if the Securities become listed on any stock exchange or automatic quotation system.

the time of its mailing to Holders of Securities, shall be mailed to the Company and filed with the Commission and each stock exchange, if any, on which the Securities are listed.

 The Company shall maintain for each series of Securities in the City of New York an office or agency where Securities of such series may be presented or surrendered for payment, where Securities of such series may be
surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Securities of such series and this Indenture may be served. The corporate trust office of The Bank of New York in the City of
New York, which on the date hereof is located at 108 Barclay Street, 8W, New York, New York 10236, shall be such office or agency of the Company, unless the Company shall designate and maintain for any series some other office or agency for one or
more of such purposes. The Company will give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the aforementioned office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands. 
 The Company may also from time to time designate one or more other offices or agencies (in
or outside of the City of New York) where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind any such designation; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office or agency in the City of New York in accordance with the requirements provided herein for such purposes. The Company will give prompt written notice to the Trustee of
any such designation or rescission and any change in the location of any such other office or agency.

 SECTION 9.3 Money for Security Payments to Be Held in Trust. 
 If the Company shall at any time act as its own Paying Agent with respect to Securities of any series, it shall, on or before each due date of the
principal of (and premium, if any, on) or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal (and premium, if any) or interest so
becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 
 Whenever the Company shall have one or more Paying Agents for Securities of any series, it will, on or before 11:00 A.M., New York City time, on each due
date of the principal of (and premium, if any, on), or interest on, any Securities of that series, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for
the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of such action or any failure so to act. 
 The Company shall cause each Paying Agent for Securities of any series (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: 
 (a) hold all
sums held by it for the payment of the principal of (and premium, if any, on) or interest on Securities of the series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as
herein provided; 
 (b) give the Trustee notice of any default by the Company (or any other obligor upon Securities of that series) in the
making of any payment of principal (and premium, if any) or interest; and 
 (c) at any time during the continuance of any such default, upon
the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. 
 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 sums. 
 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 (and premium, if any, on) or interest on any Security of any series and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Company
on Company Request unless an abandoned property law designates another person, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability 

  

 47 








 
of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published
on each Business Day and of general circulation in the city of each place of payment of principal of, (and premium, if any on) and interest on Securities of the relevant series notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company. 
 SECTION 9.4 Corporate Existence. 
 Except as expressly permitted by
Article VII or other provisions of this Indenture, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect the corporate existence, rights (charter and statutory) and franchises of the Company
and each Restricted Subsidiary; provided, however, that the Company shall not be required to preserve any such existence of its Restricted Subsidiaries, 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 its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not disadvantageous in any material respect to Holders of Securities of any series.

 SECTION 9.5 Payment of Taxes and Other Claims. 
 The Company shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Restricted Subsidiary or upon the income, profits or Property of the Company or any Restricted Subsidiary and (b) all lawful claims for labor, materials and supplies, which, if
unpaid, might by law become a Lien upon the Property of the Company or any Restricted Subsidiary; 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 and for which appropriate provision has been made in accordance with GAAP. 
 SECTION 9.6 Maintenance of Properties. 
 The Company shall cause all
material Properties owned by the Company or any Restricted Subsidiary and used or held for use in the conduct of its business or the business of any Restricted Subsidiary to be maintained and kept in good condition, repair and working order
(ordinary wear and tear excepted), all as in the judgment of the Company may be necessary so that its business may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the
Company from discontinuing the maintenance of any of such Properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business or the business of any Restricted Subsidiary and not disadvantageous in any
material respect to the Holders of Securities of any series. Notwithstanding the foregoing, nothing contained in this Section 9.6 shall limit or impair in any way the right of the Company and its Restricted Subsidiaries to sell, divest and
otherwise to engage in transactions that are otherwise permitted by this Indenture. 
  

 48 








 SECTION 9.7 Insurance. 
 The Company shall at all times keep all of its and its Restricted Subsidiaries’ Properties which are of an insurable nature insured (including
appropriate self-insurance) with insurers, believed by the Company to be responsible, against loss or damage to the extent that, in the reasonable good faith opinion of the Company, property of similar character is usually so insured by corporations
similarly situated and owning like properties. 
 The Company may adopt such other plan or method of protection, in lieu of or supplemental
to insurance with insurers, whether by the establishment of an insurance fund or reserve to be held and applied to make good losses from casualties, or otherwise, conforming to the systems of self-insurance, in the reasonable good faith opinion of
the Company, maintained by corporations similarly situated and owning like properties, as may be determined by the Board of Directors. 
 SECTION 9.8 Statement by Officers as to Default. 
 (a) The Company shall deliver to the Trustee,
within 90 days after the end of each fiscal year of the Company an Officers’ Certificate, one of the signers of which shall be the principal executive officer, principal financial officer or principal accounting officer of the Company, stating
that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and
fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of such Officer’s knowledge the Company has kept, observed, performed and fulfilled each and every covenant
contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions hereof (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of
which such Officer may have knowledge and what action the Company is taking or proposes to take with respect thereto). Such Officers’ Certificate shall comply with TIA Section 314(a)(4). For purposes of this Section 9.8(a), such
compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture. 
 (b) The Company shall,
so long as any Securities of any series are Outstanding, deliver to the Trustee forthwith upon any Officer becoming aware of any Default or Event of Default or default in the performance of any covenant, agreement or condition contained in this
Indenture, an Officers’ Certificate specifying such Default or Event of Default and what action the Company proposes to take with respect thereto within 10 days of its occurrence. 
 SECTION 9.9 Reports. 
 The Company shall file on a timely basis with the
Commission, to the extent such filings are accepted by the Commission and whether or not the Company has a class of securities 

  

 49 








 
registered under the Exchange Act, the annual reports, quarterly reports and other documents that the Company would be required to file if it were subject to
Section 13 or 15(d) of the Exchange Act). The Company will also file with the Trustee copies of such reports and documents within 15 days after the date on which the Company files such reports and documents with the Commission or the date on
which the Company would be required to file such reports and documents if the Company were so required. The Company also will furnish at its cost copies of such reports and documents to any Holder of Securities promptly upon written request,
irrespective of whether or not the Company files any such report or document with the Commission. The Company also shall comply with other provisions of TIA Section 314(a). 
 Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not
constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely
exclusively on Officers’ Certificates). 
 SECTION 9.10 Limitation on Liens. 
 (a) The Company shall not, and shall not permit any Restricted Subsidiary to, create, incur, assume or suffer to exist any Lien, except Permitted Liens,
upon any Principal Property or upon any Capital Stock or Indebtedness of any Restricted Subsidiary, whether owned or leased on the date of this Indenture or thereafter acquired, to secure any of its Debt (other than Securities) or any Debt of any
other Person, without in each case making effective provision whereby all Securities (together with, if it so determines, any other Debt of the Company that is not subordinate in right of payment to the prior payment in full of the Securities) shall
be secured equally and ratably with, or prior to, such Debt so long as such Debt shall be so secured. 
 (b) Notwithstanding the preceding
provisions of this Section 9.10, the Company may, and may permit any Restricted Subsidiary to, create, incur, assume or suffer to exist any Lien upon any Principal Property or upon any Capital Stock or Indebtedness of any Restricted Subsidiary
to secure its Debt (other than Securities) or Debt of any other Person that is not excepted pursuant to Section 9.10(a), without securing the Securities, provided that the aggregate principal amount of all Debt then outstanding secured
by such Lien and all other Liens not excepted pursuant to Section 9.10(a), together with all Attributable Indebtedness from Sale-leaseback Transactions, excluding Sale-leaseback Transactions permitted under the first sentence of
Section 9.11, does not exceed 15% of the Company’s Consolidated Net Tangible Assets. 
 SECTION 9.11 Limitation on
Sale-leaseback Transactions. 
 The Company shall not, and shall not permit any of its Subsidiaries to, engage in a Sale-leaseback
Transaction unless (i) the Sale-leaseback Transaction occurs within one year from the date of completion of the acquisition of the Principal Property subject thereto or the date of the completion of construction, development or substantial
repair or improvement, or commencement of full operations on such Principal Property, whichever is later; (ii) the Sale-leaseback Transaction involves a lease for a period, including renewals, of not more than three years; (iii) the
Attributable Indebtedness from the Sale-leaseback Transaction is an amount equal 

  

 50 








 
to or less than the amount that the Company or such Subsidiary would be allowed by Section 9.10 to incur as Debt secured by a Lien on the Principal
Property subject thereto without equally and ratably securing the Securities; or (iv) the Company or such Subsidiary, within a one-year period after the Sale-leaseback Transaction, applies or causes to be applied an amount not less than the net
sale proceeds from the Sale-leaseback Transaction to (A) the prepayment, repayment, redemption, reduction or retirement of any Pari Passu Debt of the Company or (B) the expenditure or expenditures for Principal Property used or to be used
in the ordinary course of the business of the Company or its Subsidiaries. Notwithstanding the preceding provisions of this Section 9.11, the Company may, and may permit any Subsidiary to, effect any Sale-leaseback Transaction that is not
excepted in the preceding sentence, provided that the Attributable Indebtedness from such Sale-leaseback Transaction and any other Sale-leaseback Transaction that is not so excepted, together with the aggregate principal amount of then
outstanding Debt (other than Securities) secured by Liens upon Principal Properties not excepted in Section 9.10(a), does not exceed 15% of the Company’s Consolidated Net Tangible Assets. 
 SECTION 9.12 Waiver of Certain Covenants. 
 The Company may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in Sections 9.5 through 9.11 if, before or after the time
for such compliance, the Holders of at least a majority in principal amount of the Outstanding Securities of each series affected, by Act of such Holders, waive such compliance in such instance with such term, provision or condition, but no such
waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term,
provision or condition shall remain in full force and effect. 
 ARTICLE X 
 REDEMPTION OF SECURITIES 
 SECTION 10.1 Applicability of Article.

 Securities of any series that are redeemable before their Stated Maturity shall be redeemable in accordance with the terms of such
Securities and, unless otherwise provided in such terms, this Article. 
 SECTION 10.2 Election to Redeem; Notice to
Trustee. 
 The election of the Company to redeem any Securities shall be evidenced by a Board Resolution. In case of any redemption at
the election of the Company, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), furnish to the Trustee an Officers’ Certificate setting forth
such Redemption Date, the Redemption Price and, if less than all the Securities of a series are to be redeemed, the principal amount of Securities of the series to be redeemed and shall deliver to the 

  

 51 








 
Trustee such documentation and records as shall enable the Trustee to select the Securities to be redeemed pursuant to Section 10.3. Any election to
redeem Securities shall be revocable until the Company gives a notice of redemption pursuant to Section 10.4 to the Holders of Securities to be redeemed. 
 SECTION 10.3 Selection by Trustee of Securities to Be Redeemed. 
 If less than all the Securities
of any series are to be redeemed, the particular Securities to be redeemed shall be selected not less than 30 days nor more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously
called for redemption, at random, which may provide for the selection for redemption of portions of the principal of Securities of such series; provided, however, that any such partial redemption shall be in integral multiples of $1,000.

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

 SECTION 10.4 Notice of Redemption. 
 Notice of redemption shall be given in the manner provided for in Section 13.5 not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed. 
 All notices of redemption shall identify the Securities to be redeemed (including CUSIP number) and shall state: 
 (a) the Redemption Date; 
 (b) the
Redemption Price; 
 (c) if less than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case of a
partial redemption of any series, the principal amounts) of the particular Securities to be redeemed; 
 (d) that on the Redemption Date the
Redemption Price (together with accrued interest to the Redemption Date payable as provided in Section 10.6) will become due and payable upon each such Security, or the portion thereof, to be redeemed, and that, unless the Company shall default
in the payment of the Redemption Price and any applicable accrued interest, interest thereon will cease to accrue on and after said date; 
  

 52 








 (e) if applicable, that the redemption is for a sinking fund; and 
 (f) the place or places where such Securities are to be surrendered for payment of the Redemption Price. 
 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the
Trustee in the name and at the expense of the Company. Notice, if given in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice or
any defect therein to the Holder of any Security of a series shall not affect the validity of any proceedings for the redemption of other Security of such series. 
 SECTION 10.5 Deposit of Redemption Price. 
 On or before 11:00 A.M., New York City time, on any
Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 9.3) an amount of money sufficient to pay the
Redemption Price of, and accrued and unpaid interest on, all the Securities which are to be redeemed on such Redemption Date. 
 SECTION 10.6 Securities Payable on Redemption Date. 
 Notice of redemption having been given as
aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified (together with accrued and unpaid interest to the Redemption Date), and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued and unpaid interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be
paid by the Company at the Redemption Price, together with accrued and unpaid interest to the Redemption Date; 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 Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 2.15. 
 If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate borne by the Security. 
 SECTION 10.7 Securities Redeemed in Part.

 Any Security which is to be redeemed only in part shall be surrendered at the office or agency of the Company maintained for such purpose
pursuant to Section 9.2 (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 such Holder’s
attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series and of like tenor, of any
authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal amount of the Security so surrendered. 
  

 53 








 SECTION 10.8 Optional Redemption at Make-Whole Price. 
 At any time and from time to time, the Company may, at its option, redeem all or any portion of any series of Securities at the Make-Whole Price plus
accrued and unpaid interest on such Securities so redeemed to the Redemption Date. Any redemption pursuant to this Section 10.8 shall be made, to the extent applicable, pursuant to the provisions of Sections 10.2 through 10.7. 
 SECTION 10.9 Sinking Fund. 
 The terms of the Securities of any series may provide for a sinking fund for the retirement of Securities of that series. The following provisions shall apply to any such sinking fund except as otherwise specified for the Securities of such
series. 
 (a) The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as
a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund payment.” 
 (b) In lieu of making all or any part of any mandatory sinking fund payment in cash with respect to any Securities of a series, the Company may at its
option satisfy all or part of its sinking fund payment obligation with respect to such Securities by (i) delivery of Outstanding Securities of that series theretofore purchased or otherwise acquired by the Company (other than any Securities
previously called for redemption) or (ii) applying as a credit the principal amount of Securities of that series which have been redeemed either at the election of the Company pursuant to the terms of such Securities or through the application
of permitted optional sinking fund payments pursuant to the terms of such Securities; provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the
redemption price specified in such Securities for redemption through operation of the sinking fund, and the amount of such mandatory sinking fund payment shall be reduced accordingly. 
 (c) Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an Officers’
Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to Section 10.9(b) (including therewith delivery to the Trustee of any Securities to be so delivered), and whether the Company intends to make any permitted optional
sinking fund payment with respect to such series. Not less than 45 days prior to such sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 10.3,
and the Company shall cause notice of the redemption 

  

 54 








 
thereof to be given at its expense in the manner provided in Section 10.4 except that the notice of redemption shall also state that the Securities are
being redeemed by operation of the sinking fund. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 10.6 and 10.7. 
 ARTICLE XI 
 DEFEASANCE AND COVENANT
DEFEASANCE 
 SECTION 11.1 Company’s Option to Effect Defeasance or Covenant Defeasance. 
 Unless pursuant to Section 2.2 provision is made that this Article shall not be applicable to the Securities of any series, the Company may, at its
option by Board Resolution, at any time, with respect to the Outstanding Securities of any series, elect to have either Section 11.2 or Section 11.3 be applied to all Outstanding Securities of such series upon compliance with the
conditions set forth below in this Article XI; provided that no series of Securities that is convertible into or exchangeable for any other securities shall be subject to legal defeasance pursuant to Section 11.2. 
 SECTION 11.2 Defeasance and Discharge. 
 Upon the Company’s exercise under Section 11.1 of the option applicable to this Section 11.2, the Company shall be deemed to have been discharged from its obligations with respect to all Outstanding
Securities of the applicable series on the date the conditions set forth in Section 11.4 are satisfied (hereinafter referred to as “legal defeasance”). For this purpose, such legal defeasance means that the Company shall be deemed
(a) to have paid and discharged its obligations under the Outstanding Securities of such series; provided, however that the Securities shall continue to be deemed to be “Outstanding” for purposes of Section 11.5 and the
other Sections of this Indenture referred to in clauses (i) and (ii) below, and (b) to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of Outstanding Securities of such
series to receive, solely from the trust fund described in Section 11.4 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any, on) and interest on such Securities when such payments are due
(or at such time as the Securities would be subject to redemption at the option of the Company in accordance with this Indenture), (ii) the obligations of the Company under Sections 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 2.11, 4.8, 4.14, 5.6, 5.9, 5.10,
9.1, 9.2, 9.3 and 9.4, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) the obligations of the Company under this Article XI. Subject to compliance with this Article XI, the Company may
exercise its option under Section 11.1 applicable to this Section 11.2 notwithstanding the prior exercise of its option under Section 11.1 applicable to Section 11.3. 
  

 55 








 SECTION 11.3 Covenant Defeasance. 
 Upon the Company’s exercise under Section 11.1 of the option applicable to this Section 11.3, the Company shall be released from its
obligations under any covenant contained in Sections 9.5 through 9.11 (and any other covenant, as may be determined pursuant to Section 2.1, of the applicable series of Securities subject to this provision), except the covenants contained in
Section 9.8(a) and in the final sentence of the first paragraph of Section 9.9, with respect to the Outstanding Securities of the applicable series on and after the date the conditions set forth below are satisfied (hereinafter referred to
as “covenant defeasance”), and the Securities of such series shall thereafter be deemed not to be “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to the Outstanding Securities of such series,
the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by
reason of any reference in any such covenant to any other provision herein or in any other document, and such omission to comply shall not constitute a Default or an Event of Default under Section 4.1(d) or any additional Event of Default
included in the Securities of such series, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby. 
 SECTION 11.4 Conditions to Defeasance or Covenant Defeasance. 
 The following shall be the
conditions to application of either Section 11.2 or Section 11.3 to the Outstanding Securities of any series: 
 (a) The Company
shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 5.7 who shall agree to comply with the provisions of this Article XI applicable to it) as trust funds in
trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities of such series, (i) cash in U.S. Dollars in an amount, or (ii) U.S.
Government Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount or (iii) a
combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee
(or other qualifying trustee) to pay and discharge, the principal of (and premium, if any, on) and interest on the Outstanding Securities of such series on the Stated Maturity (or Redemption Date, if applicable) of such principal (and premium, if
any) or installment of interest; provided that the Trustee shall have been irrevocably instructed in writing by the Company to apply such money or the proceeds of such U.S. Government Obligations to said payments with respect to the
Securities of such series. Before such a deposit, the Company may give to the Trustee, in accordance with Section 10.2, a notice of its election to redeem all of the Outstanding Securities of such series at a future date in accordance with
Article X, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in 

  

 56 








 
applying the foregoing. For this purpose, “U.S. Government Obligations” means securities that are (x) direct obligations of the United States
of America for the timely payment of which its full faith and credit is pledged or (y) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of America the timely payment of which is
unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case, are not callable or redeemable at the option of the issuer thereof, and shall also include a depository receipt issued by a bank
(as defined in Section 3(a)(2) of the Securities Act), as custodian with respect to any such U.S. Government Obligation or a specific payment of principal of or interest on any such U.S. Government Obligation held by such custodian for the
account of the holder of such depository receipt, 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 depository receipt from any amount received by
the custodian in respect of the U.S. Government Obligation or the specific payment of principal of or interest on the U.S. Government Obligation evidenced by such depository receipt. 
 (b) No Default or Event of Default with respect to the Securities of such series shall have occurred and be continuing on the date of such deposit.

 (c) Such legal defeasance or covenant defeasance shall not cause the Trustee to have a conflicting interest under this Indenture or the
Trust Indenture Act with respect to any securities of the Company. 
 (d) Such legal defeasance or covenant defeasance shall not result in a
breach or violation of, or constitute a default under any other material agreement or instrument to which the Company is a party or by which it is bound, as evidenced to the Trustee in an Officers’ Certificate delivered to the Trustee
concurrently with such deposit. 
 (e) In the case of an election applicable to Section 11.2, the Company shall have delivered to the
Trustee an Opinion of Counsel stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (ii) since the date of this Indenture there has been a change in the applicable federal
income tax laws, in either case providing that the Holders of the Outstanding Securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of such legal defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred (it being understood that (x) such Opinion of Counsel shall also state that such ruling or applicable
law is consistent with the conclusions reached in such Opinion of Counsel and (y) the Trustee shall be under no obligation to investigate the basis of correctness of such ruling). 
 (f) In the case of an election applicable to Section 11.3, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that
the Holders of the Outstanding Securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of such covenant defeasance and will be subject to federal income tax on the same amounts, in the same
manner and at the same times as would have been the case if such covenant defeasance had not occurred. 
  

 57 








 (g) The Company shall have delivered to the Trustee an Officers’ Certificate to the effect that the
Securities of such series, if then listed on any securities exchange, will not be delisted as a result of such legal defeasance or covenant defeasance. 
 (h) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to either the legal defeasance under
Section 11.2 or the covenant defeasance under Section 11.3 (as the case may be) have been complied with. 
 SECTION 11.5
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 9.3, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 11.5, the
“Trustee”) pursuant to Section 11.4 in respect of the Outstanding Securities of any series shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment,
either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities of all sums due and to become due thereon in respect of principal (and premium, if
any) and interest, but such money 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 11.4 or the principal and interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders of Outstanding Securities. 
 Anything in this Article XI 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 11.4 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent legal defeasance or covenant defeasance,
as applicable, in accordance with this Article. 
 SECTION 11.6 Reinstatement. 
 If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 11.5 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 Securities of the applicable series shall be revived and reinstated as though no deposit had
occurred pursuant to Section 11.2 or 11.3, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 11.5; provided, however, that if the Company makes any
payment of principal of (or premium, if any, on) or interest on any Security of a series following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the
money held by the Trustee or Paying Agent. 
  

 58 








 ARTICLE XII 
 CONVERSION 
 SECTION 12.1 Applicability; Conversion Privilege and Conversion Price. 

If Securities of any series are designated pursuant to Section 2.2 as convertible into Common Stock of the Company, such conversion shall be in
accordance with the terms of this Article, unless otherwise specified in the terms of such Securities. Conversion provisions for Securities of any series denominated in a foreign currency or for conversion into a security other than Common Stock of
the Company shall be specified in the terms of such Securities in accordance with Section 2.2. Reference in this Article to “Common Stock” shall mean the common stock, par value $0.01 per share, of the Company authorized on the date
of this Indenture and any other class of stock resulting from successive changes or reclassifications of such common stock. 
 Subject to and
upon compliance with the provisions of this Article, at the option of the Holder thereof, any Security of a series to which this Article applies, or any portion of the principal amount thereof which equals $1,000 or an integral multiple thereof, may
be converted at the principal amount thereof, or of such portion thereof, into fully paid and non-assessable shares (calculated as to each conversion to the nearest 1/100th of a share) of Common Stock, at the conversion price in effect at the time
of conversion. Such conversion right shall expire at the close of business on the date specified for Securities of such series. In case a Security or portion thereof is called for redemption, such conversion right in respect of the Security or
portion so called shall expire at the close of business on the Business Day immediately preceding the Redemption Date, unless the Company defaults in making the payment due upon redemption. 
 The price at which shares of Common Stock shall be delivered upon conversion (the “conversion price”) shall be the price specified for the
Securities of such series, subject to adjustment as provided in this Article. 
 SECTION 12.2 Conversion Procedure. 
 In order to exercise the conversion privilege, the Holder of any Security to be converted shall surrender to the Company such Security, duly endorsed or
assigned to the Company or in blank, at any office or agency of the Company maintained pursuant to Section 9.2, accompanied by written notice of conversion in substantially the form set forth in the Security (except in the case of a depositary
of a Global Security, for which the customary procedures of the depositary will apply). Securities surrendered for conversion during the period from the close of business on any Regular Record Date next preceding any Interest Payment Date to the
opening of business on such Interest Payment Date shall (except in the case of Securities or portions thereof which have been called for redemption on a Redemption Date within such period) be accompanied by 

  

 59 








 
payment in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on
the principal amount of Securities being surrendered for conversion. Except as provided in the immediately preceding sentence, no payment or adjustment shall be made upon any conversion on account of any interest accrued on the Securities
surrendered for conversion or on account of any dividends on the Common Stock issued upon conversion. 
 Securities shall be deemed to have
been converted immediately prior to the close of business on the day of surrender of such Securities for conversion in accordance with the foregoing provisions, and at such time the rights of the Holders of such Securities as Holders shall cease,
and the Person or Persons entitled to receive the Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such Common Stock at and after such time. As promptly as practicable on or after the
conversion date, the Company shall issue and shall deliver at such office or agency a certificate or certificates for the number of full shares of Common Stock issuable upon conversion, together with any payment in lieu of any fraction of a share,
as provided in Section 12.3. 
 In the case of any Security which is converted in part only, upon such conversion the Company shall
execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Security or Securities of the applicable series of authorized denominations in aggregate principal amount equal to the unconverted
portion of the principal amount of such Security. 
 SECTION 12.3 Fractions of Shares. 
 No fractional shares of Common Stock or scrip representing fractions of shares shall be issued upon conversion of Securities. If more than one Security of
a series shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Securities (or specified
portions thereof) of that series so surrendered. Instead of any fractional share of Common Stock which would otherwise be issuable upon conversion of any Security or Securities (or specified portions thereof), the Company shall pay to the Holder of
such Security an amount in cash (computed to the nearest cent) based upon the closing price of the Common Stock on the Business Day immediately preceding the date of conversion. 
 SECTION 12.4 Adjustment of Conversion Price. 
 The conversion price shall be
subject to adjustment from time to time as follows: 
 (a) In case the Company shall pay or make a dividend or other distribution on any
class of its capital stock in shares of its Common Stock, then the conversion price in effect at the opening of business on the day following the record date for determination of stockholders entitled to receive such dividend or other distribution
shall be reduced by multiplying such conversion price by a fraction of which the numerator shall be the number of shares of Common Stock issued and outstanding at the close of business on such record date and the denominator shall be the sum of such
number of shares and the total number of shares constituting such dividend or other distribution. Such reduction shall become effective immediately after the opening of business on the day following such record date. 
  

 60 








 (b) In case the Company shall issue rights, options or warrants to all holders of its outstanding shares
of Common Stock entitling them to subscribe for or purchase shares of Common Stock at a price per share less than the current market price per share of the Common Stock on the record date for determination of stockholders entitled to receive such
rights, options or warrants, then the conversion price in effect at the opening of business on the day following such record date shall be reduced by multiplying such conversion price by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding at the close of business on such record date plus the number of shares of Common Stock which the aggregate of the offering price of the total number of shares of Common Stock so offered for subscription or purchase
would purchase at such current market price and the denominator shall be the number of shares of Common Stock outstanding at the close of business on such record date plus the number of shares of Common Stock so offered for subscription or purchase.
Such reduction shall become effective immediately after the opening of business on the day following such record date. Notwithstanding the foregoing, in case the Company shall issue rights, options or warrants (“Stockholder Rights”) to all
holders of its Common Stock entitling the holders thereof to subscribe for or purchase shares of Common Stock, which rights or warrants (i) are deemed to be transferred with such shares of Common Stock, (ii) are not exercisable and
(iii) are also issued in respect of future issuances of Common Stock, in each case until the occurrence of a specified event or events, such Stockholder Rights shall for purposes of this Section 12.4 not be deemed issued or distributed
until the occurrence of the earliest of such specified events and the conversion price shall not be reduced until the occurrence of such earliest specified event. If the conversion price is reduced pursuant to this paragraph (b) as a result of
any rights, warrants or options that are issued by the Company and if at the end of the period during which such warrants, options, or rights are exercisable, not all such warrants, options or rights shall have been exercised, the conversion price
shall be immediately readjusted to what it would have been had the above fraction been computed based on the number of shares of Common Stock actually issued in respect of such warrants, options or rights, as the case may be. 
 (c) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, then the conversion price in effect
at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced by multiplying such conversion price by a fraction of which the numerator shall be the number of shares of Common
Stock outstanding at the close of business on the day upon which such subdivision becomes effective before giving effect to such subdivision and the denominator shall be the number of shares of Common Stock outstanding at the close of business on
the day such subdivision becomes effective after giving effect to such subdivision. Conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, then the conversion price in effect at the
opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased by multiplying such conversion price by a fraction of which the numerator shall be the number of shares of Common Stock
outstanding at the close of business on the day upon which such combination becomes effective before giving effect to such combination and the denominator shall be the number of shares of Common Stock outstanding at 

  

 61 








 
the close of business on the day such combination becomes effective after giving effect to such combination. Such reduction or increase, as the case may be,
shall become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. 
 (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness or assets (including securities, but excluding (i) an issuance, dividend or
distribution referred to in paragraphs (a) and (b) of this Section paid exclusively in cash or upon the dissolution, liquidation or winding up of the Company or (ii) Stockholder Rights), then the conversion price shall be adjusted so
that the same shall equal the price determined by multiplying the conversion price in effect immediately prior to the close of business on the record date for determination of stockholders entitled to receive such distribution by a fraction of which
the numerator shall be the current market price per share of the Common Stock on such record date minus the then fair market value (as determined by the Board of Directors of the Company, whose determination shall be conclusive and described in a
Board Resolution) of the portion of the evidences of indebtedness or assets so distributed applicable to one share of Common Stock and the denominator shall be such current market price per share of the Common Stock on such record date. Such
adjustment shall become effective immediately prior to the opening of business on the day following such record date. 
 (e) In case the
Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding any cash that is distributed as part of a distribution referred to in paragraph (d) of this Section) in an aggregate amount that, together
with the aggregate amount of any other distributions to all holders of its Common Stock made exclusively in cash within the l2 months preceding the date of payment of such distribution and in respect of which no conversion price adjustment pursuant
to this paragraph (e) has been made, exceeds 10% of the product of the current market price per share of the Common Stock on the date fixed for the determination of stockholders entitled to receive such distribution multiplied by the number of
shares of Common Stock outstanding on such date, then the conversion price shall be reduced so that the same shall equal the price determined by multiplying the conversion price in effect immediately prior to the effectiveness of the conversion
price reduction contemplated by this paragraph (e) by a fraction of which the numerator shall be the current market price per share of the Common Stock on such date minus the amount of cash so distributed applicable to one share of Common Stock
and the denominator shall be such current market price per share of the Common Stock. Such reduction shall become effective immediately prior to the opening of business on the date following the date fixed for the payment of such distribution.

 (f) The reclassification of Common Stock into securities other than Common Stock (excluding any reclassification upon a merger or
consolidation to which Section 12.12 applies) shall be deemed to involve a distribution of such securities other than Common Stock to all holders of Common Stock (and the effective date of such reclassification shall be deemed to be “the
record date for determination of stockholders entitled to receive such distribution” within the meaning of paragraph (d) of this Section). If such reclassification changes the number of outstanding shares of Common Stock, then such
reclassification shall be deemed (in addition to any effect provided in the previous sentence) a subdivision or combination, as the case may be, of the number of shares of Common Stock outstanding immediately prior to such reclassification 

  

 62 








 
into the number of shares of Common Stock outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be “the
day upon which such subdivision becomes effective” or “the day upon which such combination becomes effective”, as the case may be, within the meaning of paragraph (c) of this Section). 
 (g) No adjustment in the conversion price shall be required unless such adjustment would require an increase or decrease of at least 1% in such price;
provided that any adjustment which by reason of this paragraph (g) is not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article shall be made to the nearest
cent or to the nearest 1/100th of a share, as the case may be. No adjustment in the conversion price shall be required for any increase or decrease in the par value of the Common Stock. 
 (h) In addition to the adjustments in conversion price required by paragraphs (a), (b), (c), (d), (e) and (f) of this Section, the Company may
from time to time in its discretion make such decreases in the conversion price as it considers to be advisable, including for purposes of avoiding or diminishing any federal income tax to any holders of shares of Common Stock resulting from any
dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for federal income tax purposes or for any other reason. 
 (i) Notwithstanding any other provision of this Article XII, no adjustment to the conversion price shall result in zero or in a negative number or shall
reduce the conversion price below the then par value per share of the Common Stock, and any such purported adjustment shall instead reduce the conversion price to such par value, unless the Common Stock then has no par value, in which case such
purported adjustment shall instead reduce the conversion price to $.01 per share. The Company hereby covenants not to take any action to increase the par value per share of the Common Stock. 
 (j) For the purpose of any computation in this Article, the current market price per share of Common Stock on any date shall be deemed to be the average
of the closing prices for the 5 consecutive days (on which securities exchanges are open for trading) preceding such date of determination. The closing price for each day shall be the last reported sales price regular way or, if no such reported
sale takes place on such day, the average of the reported closing bid and asked prices regular way, in either case as reported for consolidated transactions on the New York Stock Exchange or, if the Common Stock is not listed or admitted to trading
on the New York Stock Exchange, on the principal national securities exchange on which the Common Stock is listed or admitted to trading or, if the Common Stock is not so listed or admitted to trading, on the Nasdaq Stock Market or, if the Common
Stock is not so listed or admitted to trading, the average of the closing bid and asked prices (or if closing bid and asked prices or not available, the average of the high bid and low asked prices for such day) in the over-the-counter market as
published by the appropriate regulatory organization or if not so published as furnished by any New York Stock Exchange member firm selected from time to time by the Company. 
  

 63 








 SECTION 12.5 Notice of Adjustments of Conversion Price. 
 Whenever the conversion price is adjusted as herein provided, the Company shall promptly: 
 (i) compute the adjusted conversion price in accordance with Section 12.4 and prepare a certificate signed by the chief financial
officer or the Treasurer of the Company setting forth the adjusted conversion price and showing in reasonable detail the facts upon which such adjustment is based, and file such certificate (with a copy to the Trustee) at each office or agency
maintained for the purpose of conversion of Securities pursuant to Section 9.2; and 
 (ii) prepare a notice stating that
the conversion price has been adjusted and setting forth the adjusted conversion price, and as soon as practicable thereafter mail such notice to Holders of Securities providing the conversion right contained in this Article XII at their last
addresses as they shall appear in the Securities Register. 
 SECTION 12.6 Trustee’s Adjustment Disclaimer. 
 The Trustee has no duty to determine when an adjustment under this Article XII should be made, how it should be made or the amount it should be. The
Trustee shall not be accountable for and makes no representation as to the validity or value of any securities or assets issued upon conversion of any Securities. The Trustee shall not be responsible for the Company’s failure to comply with
this Article XII. 
 SECTION 12.7 Notice of Certain Corporate Actions. 
 In case the Company shall authorize: 
 (i) any event which could result in an adjustment in the conversion price under Section 12.4 or require the execution of a supplemental indenture under Section 12.12; or 
 (ii) the granting to holders of its Common Stock generally of rights, options or warrants to subscribe for or purchase any shares of
Capital Stock excluding Stockholder Rights); or 
 (iii) any reclassification of the Common Stock, or any merger,
consolidation or share exchange to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or transfer of the properties and assets of the Company substantially as an entirety; or

 (iv) the voluntary or involuntary dissolution, liquidation or winding up of the Company; 
  

 64 








 then the Company shall cause to be filed at each office or agency maintained pursuant to Section 9.2, and shall
cause to be mailed to all Holders of Securities providing the conversion right contained in this Article XII at their last addresses as they shall appear in the Security Register, at least 15 days prior to the applicable record, effective or
expiration date hereinafter specified, a notice stating (A) the date on which a record is to be taken for the purpose of such dividend, distribution or granting of rights, options or warrants, or, if a record is not to be taken, the date as of
which the holders of Common Stock of record who will be entitled to such dividend, distribution, rights or warrants are to be determined, or (B) the date on which such reclassification, merger, consolidation, share exchange, sale, transfer,
dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property
deliverable upon such reclassification, merger, consolidation, share exchange, sale, transfer, dissolution, liquidation or winding up. Neither the failure to give any such notice nor any defect therein shall affect the legality or validity of any
action described in this Article XII. In case of the occurrence of any event triggering the exercisability of Stockholder Rights, then the Company shall cause to be filed at each office or agency maintained pursuant to Section 9.2, and shall
cause to be mailed to the Holders of Securities providing the conversion right contained in this Article XII at their last addresses as they shall appear in the Security Register within 10 days after the occurrence of such event a notice of such
event and the date of its occurrence. 
 SECTION 12.8 Company to Reserve Common Stock. 
 The Company shall at all times reserve and keep available, free from preemptive rights, out of the authorized but unissued Common Stock or out of the
Common Stock held in treasury, for the purpose of effecting the conversion of Securities, the full number of shares of Common Stock then issuable upon the conversion of all outstanding Securities so convertible. 
 SECTION 12.9 Taxes on Conversions. 
 The Company will pay any and all documentary, stamp or similar issue or transfer taxes that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto. The Company shall not,
however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder of the Security or Securities to be converted, and no such issue
or delivery shall be made unless and until the Person requesting such issue has paid to the Company the amount of any such tax, or has established to the satisfaction of the Company that such tax has been paid. 
 SECTION 12.10 Covenant as to Common Stock. 
 The Company covenants that all shares of Common Stock issued upon conversion of Securities will be validly issued, fully paid and non assessable. 
  

 65 








 SECTION 12.11 Cancellation of Converted Securities. 
 All Securities delivered for conversion shall be delivered to the Trustee to be cancelled by or at the direction of the Trustee, which shall dispose of
the same as provided in Section 2.14. 
 SECTION 12.12 Effect of Merger, Consolidation or Sale of Assets. 
 In case of any merger of the Company into or consolidation of the Company with any other Person, any merger of another Person into the Company (other than
a merger which does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock) or any sale or transfer of the properties and assets of the Company substantially as an entirety, the Person
resulting from such merger or consolidation or which acquires such properties and assets of the Company, as the case may be, shall execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security providing the
conversion right contained in this Article XII that is then outstanding shall have the right thereafter, during the period such Security shall be convertible as specified in Section 12.1, to convert such Security only into the kind and amount
of securities, cash and other property, if any, receivable upon such merger, consolidation, sale or transfer by a holder of the number of shares of Common Stock into which such Security might have been converted immediately prior to such merger,
consolidation, sale or transfer, assuming such holder of Common Stock (i) is not a Person into which the Company merged or which merged into the Company or with which the Company consolidated or to which such sale or transfer was made, as the
case may be (a “Constituent Person”), or an Affiliate of a Constituent Person, and (ii) failed to exercise his rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such merger,
consolidation, sale or transfer (provided that if the kind or amount of securities, cash and other property receivable upon such merger, consolidation, sale or transfer is not the same for each share of Common Stock held immediately prior to such
merger, consolidation, sale or transfer by other than a Constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised (“nonelecting share”), then for the purpose of this
Section 12.12 the kind and amount of securities, cash and other property receivable upon such merger, consolidation, sale or transfer by each nonelecting share shall be deemed to be the kind and amount so receivable per share by a plurality of
the nonelecting shares). Such supplemental indenture shall provide for adjustments which, for events subsequent to the effective date of such supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments provided for
in this Article XII. The above provisions of this Section shall similarly apply to any successive merger, consolidation, sale or transfer. No adjustment in the conversion price shall be made pursuant to Section 12.4 as a result of any merger,
consolidation, sale or transfer of the properties and assets of the Company substantially as an entirety to which this Section 12.12 applies. 
  

 66 








 ARTICLE XIII 
 MISCELLANEOUS 
 SECTION 13.1 Compliance Certificates and Opinions. 
 Upon any application or request by the Company to the Trustee to take any action under any provision of this Indenture, the Company shall furnish to the
Trustee such certificates and opinions as may be required under the Trust Indenture Act or this Indenture. Each such certificate and each such opinion shall be in the form of an Officers’ Certificate or an Opinion of Counsel, as applicable, and
shall comply with the requirements of this Indenture. 
 Every certificate or opinion with respect to compliance with a condition or covenant
provided for in this Indenture shall include: 
 (i) a statement that each individual signing such certificate or opinion has
read such covenant or condition and the definitions herein relating thereto; 
 (ii) a brief statement as to the nature and
scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based; 
 (iii) a statement that, in the opinion of each such individual, he has made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been complied
with; and 
 (iv) a statement as to whether, in the opinion of each such individual, such condition or covenant has been
complied with. 
 The certificates and opinions provided pursuant to this Section 13.1 and the statements required by this
Section 13.1 shall comply in all respects with TIA Sections 314(c) and (e). 
 SECTION 13.2 Form of Documents Delivered to
Trustee. 
 In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is
not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters
and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. 
 Any certificate or opinion of an Officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the
exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such Opinion of Counsel may be based, insofar as it relates to
factual 

  

 67 








 
matters, upon an Officers’ Certificate of an Officer or Officers of the Company stating that the information with respect to such factual matters is in
the possession of the Company, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate with respect to such matters is erroneous. 
 Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and form one instrument. 
 SECTION 13.3 Acts of
Holders. 
 (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be
given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing; and, 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 shall be sufficient for any purpose of this Indenture and
conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. 
 (b) 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
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. 
 (c) The ownership, principal amount and serial numbers of Securities of any series held by any Person, and the date of holding the same, shall be proved
by the Security Register. 
 (d) If the Company shall solicit from Holders of Securities of any series any request, demand, authorization,
direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction,
notice, consent, waiver or other Act, but the Company shall have no obligation to do so. Notwithstanding TIA Section 316(c), such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not
earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction,
notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the 

  

 68 








 
purposes of determining whether Holders of the requisite proportion of Outstanding Securities of a series have authorized or agreed or consented to such
request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities of a series shall be computed as of such record date; provided that no such authorization, agreement or consent
by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven months after the record date. 
 (e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of
the same Security and the Holder of every Security 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 Security. 
 SECTION 13.4 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: 
 (i) the Trustee by any Holder or by the
Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing and delivered in person or mailed by certified or registered mail (return receipt requested) to the Trustee at its Corporate Trust Office; or

 (ii) 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 delivered in person or mailed by certified or registered mail (return receipt requested) to the Company addressed to it at the Company’s principal office located at 810 Houston Street, Fort Worth, Texas
76102, or at any other address otherwise furnished in writing to the Trustee by the Company. 
 SECTION 13.5 Notice to Holders;
Waiver. 
 Where this Indenture provides for notice of any event to Holders by the Company or the Trustee, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date, and
not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such
notice. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of
notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. 
  

 69 








 In case by reason of the suspension of or irregularities in regular mail service or by reason of any
other cause, it shall be impracticable to mail notice of any event to Holders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee shall
be deemed to be a sufficient giving of such notice for every purpose hereunder. 
 SECTION 13.6 Effect of Headings and Table of
Contents. 
 The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the
construction hereof. 
 SECTION 13.7 Successors and Assigns. 
 All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not. All agreements of the
Trustee in this Indenture shall bind its successor. 
 SECTION 13.8 Separability Clause. 
 In case any provision in this Indenture or in the Securities of any series 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, and a Holder shall have no claim therefore against any party hereto. 
 SECTION 13.9 Benefits of Indenture. 
 Nothing in this Indenture or in the
Securities of any series, express or implied, shall give to any Person (other than the parties hereto, any Paying Agent, any Securities Registrar and their successors hereunder and the Holders) any benefit or any legal or equitable right, remedy or
claim under this Indenture. 
 SECTION 13.10 Governing Law; Trust Indenture Act Controls. 
 (a) THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK, EXCEPT TO THE EXTENT THE
TRUST INDENTURE ACT IS APPLICABLE. THE COMPANY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR NEW YORK STATE COURT SITTING IN THE BOROUGH OF MANHATTAN, THE CITY OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING
OUT OF OR RELATING TO THIS INDENTURE OR THE SECURITIES, AND THE COMPANY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED BY ANY SUCH COURT. 
  

 70 








 (b) This Indenture is subject to the provisions of the Trust Indenture Act that are required to be part
of this Indenture and shall, to the extent applicable, be governed by such provisions. If and to the extent that any provision of this Indenture limits, qualifies or conflicts with the duties imposed by Sections 310 to 317, inclusive, of the Trust
Indenture Act, or conflicts with any provision (an “incorporated provision”) required by or deemed to be included in this Indenture by operation of Section 318(c) of the Trust Indenture Act, such imposed duties or incorporated
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
excluded, as the case may be. 
 SECTION 13.11 Legal Holidays. 
 In any case where any Interest Payment Date, Redemption Date, or Stated Maturity or Maturity of any Security shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Securities of any series) payment of interest or principal (and premium, if any) need not be made on such date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the Interest Payment Date, Redemption Date or at the Stated Maturity or Maturity; provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date, Stated Maturity or
Maturity, as the case may be. 
 SECTION 13.12 No Recourse Against Others. 
 A director, officer, employee or stockholder of the Company shall not have any liability, by reason of his or its status as such director, officer,
employee or stockholder, for any obligations of the Company under the Securities of any series or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder, by accepting any Security,
waives and releases all such liability to the extent permitted by applicable law. 
 SECTION 13.13 Duplicate Originals.

 The parties may sign any number of copies or counterparts of this Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement. 
 SECTION 13.14 No Adverse Interpretation of Other Agreements. 
 This Indenture may not be used to interpret another indenture, loan or debt agreement of the Company or any of its Subsidiaries. Any such indenture, loan
or debt agreement may not be used to interpret this Indenture.

             and              of each year, from
            , or from the most recent Interest Payment Date to which interest has been paid or duly provided for, at the rate of

 TRUSTEE’S CERTIFICATE OF AUTHENTICATION 
 This is one of the Securities of the series designated herein and referred to in the within-mentioned Indenture. 
  

									
	Dated: ________	 		 	 [TRUSTEE]
 as Trustee

					
		 		 		 	By	 	  
		 		 		 		 	Authorized Signatory

  

 A-3 








 [Form of Reverse] 
 This Security is one of a duly authorized issue of the series of securities of the Company designated as its [name of designated series] (herein called the “Securities”), which is issued under, with
securities of one or more additional series that may be issued under, the indenture (herein called the “Indenture”) dated as of July 19, 2007 between the Company and The Bank of New York Trust Company, N.A., as trustee
(herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all applicable indentures supplemental thereto reference is hereby made for a statement of the respective rights,
limitations of rights, duties, obligations and immunities thereunder of the Company, the Trustee and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered. 
 [If applicable, insert: The Securities are subject to redemption at the option of the Company, in whole or in part, at any time and from time to time,
upon not less than 30 or more than 60 days’ notice, at a Redemption Price of 100% of their principal amount plus a Make-Whole Amount, together in the case of any such redemption with accrued and unpaid interest to the Redemption Date (subject
to the right of Holders of record on the relevant Regular Record Date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date), all as provided in the Indenture. 
 In the case of any redemption of Securities, interest installments whose Stated Maturity is on or prior to the Redemption Date will be payable to the
Holders of such Securities, or one or more Predecessor Securities, of record at the close of business on the relevant Record Date referred to on the face hereof. Securities (or portions thereof) for whose redemption and payment provision is made in
accordance with the Indenture shall cease to bear interest from and after the Redemption Date. 
 In the event of redemption of this Security
in part only, a new Security or Securities for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof.] 
 [If applicable insert: The Securities do not have the benefit of any sinking fund or mandatory repurchase obligations.] 
 As set forth in the Indenture, an Event of Default is generally (a) failure to pay principal upon Stated Maturity, redemption or otherwise; (b) default for 30 days in payment of interest on any of the
Securities; (c) default in the performance of agreements relating to mergers, consolidations and sales of all or substantially all assets; (d) failure for 30 days after notice to comply with any other covenants in the Indenture or the
Securities; (e) certain payment defaults under, or the acceleration prior to the maturity of, Debt of the Company or any Restricted Subsidiary in an aggregate principal amount in excess of $50,000,000; and (f) certain events of bankruptcy,
insolvency or reorganization of the Company. [If applicable, insert additional events of default.] 
  

 A-4 








 If any Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in aggregate
principal amount of the Outstanding Securities may declare the principal amount of all the Securities to be due and payable immediately, except that (i) in the case of an Event of Default arising from certain events of bankruptcy, insolvency or
reorganization of the Company, the principal amount of the Securities will become due and payable immediately without further action or notice and (ii) in the case of an Event of Default which relates to certain payment defaults or acceleration
with respect to certain Debt, any acceleration of the Securities will be automatically rescinded if any such Debt is repaid or if the default relating to such Debt is cured or waived and if the holders thereof have accelerated such Debt then such
holders have rescinded their declaration of acceleration. 
 No Holder may pursue any remedy under the Indenture unless the Trustee shall
have failed to act after notice of an Event of Default and written request by Holders of at least 25% in principal amount of the Outstanding Securities, and the offer to the Trustee of indemnity reasonably satisfactory to it; however, such provision
does not affect the right to sue for enforcement of any overdue payment on a Security by the Holder thereof. Subject to certain limitations, Holders of a majority in principal amount of the Outstanding Securities may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except default in payment of principal, premium or interest) if it determines in good faith that withholding the notice is in the interest of the
Holders. The Company is required to file quarterly reports with the Trustee as to the absence or existence of defaults. 
 [If applicable
insert: The Indenture contains provisions for defeasance at any time of (i) the entire indebtedness of the Company on this Security and (ii) certain restrictive covenants and the related Defaults and Events of Default, upon compliance by
the Company with certain conditions set forth therein, which provisions apply to this Security.] 
 The Indenture permits, with certain
exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities at the time Outstanding, on
behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by or on behalf of the Holder
of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof whether or not notation of
such consent or waiver is made upon this Security. Without the consent of any Holder, the Company and the Trustee may amend or supplement the Indenture or the Securities to cure any ambiguity, defect or inconsistency, to provide for uncertificated
Securities in addition to or in place of Definitive Securities and to make certain other specified changes and other changes that do not adversely affect the rights of any Holder in any material respect. 
  

 A-5 








 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or
impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any, on) and interest on this Security at the times, place, and rate, and in the coin or currency, herein prescribed. 
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registerable in the Security
Register, upon surrender of this Security for registration of transfer at the office or agency of the Company maintained for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and
the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees. 
 The Securities are issuable only in registered form without coupons in denominations of $1,000 and
any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Securities are exchangeable for a like aggregate principal amount of Securities of a different authorized denomination, as
requested by the Holder surrendering the same. 
 No service charge shall be made for any registration of transfer or exchange of Securities,
but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith. 
 A director, officer, employee or stockholder of the Company shall not have any personal liability under this Security or the Indenture by reason of his or its status as such director, officer, employee or stockholder. Each Holder, by
accepting this Security, waives and releases all such liability. Such waiver and release are part of the consideration for the issuance of this Security. 
 Prior to the time of due presentment of this Security 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 Security is registered
as the owner hereof for all purposes, whether or not this Security is overdue, and neither the Company, the Trustee nor any agent shall be affected by notice to the contrary. 
 All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture. The Company will furnish to
any Holder upon written request and without charge a copy of the Indenture. Requests may be made to the Company, 810 Houston Street, Fort Worth, Texas 76102. 
 Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders thereof. No
representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identifying information printed hereon.
