 The Company, the Guarantors (as defined) and the Trustee
(as defined) agree as follows for the benefit of each other and for the equal and ratable benefit of the Holders (as defined) of the 8.25% Senior Notes due 2014 (the “Notes”): 
 ARTICLE 1 
 DEFINITIONS AND INCORPORATION 
 BY REFERENCE 
 Section 1.01 Definitions.

 “144A Global Note” means a Global Note substantially in the form of Exhibit A hereto bearing the Global Note Legend and
the Private Placement Legend and deposited with or on behalf of, and registered in the name of, the Depositary or its nominee that will be issued in a denomination equal to the outstanding principal amount of the Notes sold in reliance on Rule 144A.

 “Acquired Debt” means, with respect to any specified Person: 
 (1) Indebtedness of any other Person existing at the time such other Person is merged with or into or became a Subsidiary of such
specified Person, whether or not such Indebtedness is incurred in connection with, or in contemplation of, such other Person merging with or into, or becoming a Restricted Subsidiary of, such specified Person, but excluding Indebtedness which is
extinguished, retired or repaid in connection with such Person merging with or becoming a Subsidiary of such specified Person; and 
 (2) Indebtedness secured by a Lien encumbering any asset acquired by such specified Person. 
 “Additional Notes”
means additional Notes (other than the Initial Notes) issued under this Indenture in accordance with Sections 2.02 and 4.09 hereof, as part of the same series as the Initial Notes.  
 “Additional Assets” means: 
 (1) any assets that are not classified as current assets under GAAP and that are used or useful in the Oil and Gas Business, other than Indebtedness or Capital Stock; 
 (2) the Capital Stock of a Person that becomes a Restricted Subsidiary as a result of the acquisition of such Capital Stock by the Company
or any of its Restricted Subsidiaries; or 
 (3) Capital Stock constituting a minority interest in any Person that at such
time is a Restricted Subsidiary; 
 provided, however, that any such Restricted Subsidiary described in clause (2) or (3) is primarily
engaged in the Oil and Gas Business. 
 “Adjusted Consolidated Net Tangible Assets” means (without duplication), as of the
date of determination: 
 (1) the sum of: 
 (a) discounted future net revenue from proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries calculated
in accordance with SEC guidelines before any state or federal income taxes, as estimated in a reserve report prepared as of the end of the fiscal year ending at least 91 days prior to the date of determination, which reserve report is prepared,
reviewed or audited by independent petroleum engineers as increased by, as of the date of determination, the discounted future net revenue of: 
 (i) estimated proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries attributable to acquisitions consummated since the date of such reserve report, and 
  

 1 

 (ii) estimated crude oil and natural gas reserves of the Company and its Restricted
Subsidiaries attributable to extensions, discoveries and other additions and upward determinations of estimates of proved crude oil and natural gas reserves (including previously estimated development costs incurred during the period and the
accretion of discount since the prior period end) due to exploration, development or exploitation, production or other activities which reserves were not reflected in such reserve report which would, in accordance with standard industry practice,
result in such determinations, in each case calculated in accordance with SEC guidelines (utilizing the prices utilized in such year-end reserve report), 
 and decreased by, as of the date of determination, the discounted future net revenue attributable to: 
 (iii) estimated proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries reflected in such reserve report produced or disposed of since the date of such reserve report, and 

(iv) reductions in the estimated oil and natural gas reserves of the Company and its Restricted Subsidiaries reflected in such reserve
report since the date of such reserve report attributable to downward determinations of estimates of proved crude oil and natural gas reserves due to exploration, development or exploitation, production or other activities conducted or otherwise
occurring since the date of such reserve report which would, in accordance with standard industry practice, result in such determinations, in each case calculated in accordance with SEC guidelines (utilizing the prices utilized in such reserve
report); 
 provided, however, that, in the case of each of the determinations made pursuant to clauses (i) through (iv), such
increases and decreases shall be estimated by the Company’s engineers, except that if as a result of such acquisitions, dispositions, discoveries, extensions or revisions, there is a Material Change, then such increases and decreases in the
discounted future net revenue shall be confirmed in writing by an independent petroleum engineer; 
 (b) the capitalized costs
that are attributable to crude oil and natural gas properties of the Company and its Restricted Subsidiaries to which no proved crude oil and natural gas reserves are attributable, based on the Company’s books and records as of a date no
earlier than the date of the Company’s latest available annual or quarterly financial statements; 
  

 2 

 (c) the Net Working Capital (excluding, to the extent included in the determination of
discounted future net revenues under clause (1)(a) above, any adjustments made pursuant to FAS 143) as of a date no earlier than the date of the Company’s latest available annual or quarterly financial statements; and 
 (d) the greater of (i) the net book value as of a date no earlier than the date of the Company’s latest available annual or
quarterly financial statements and (ii) the appraised value, as estimated by independent appraisers, of other tangible assets of the Company and its Restricted Subsidiaries as of a date no earlier than the date of the Company’s latest
available annual or quarterly financial statements (provided that the Company shall not be required to obtain such an appraisal of such assets if no such appraisal has been performed); minus  
 (2) the sum of: 
 (a)
Minority Interests; 
 (b) any net natural gas balancing liabilities of the Company and its Restricted Subsidiaries reflected
in the Company’s latest audited financial statements; 
 (c) to the extent included in clause (1)(a) above, the
discounted future net revenue, calculated in accordance with SEC guidelines (utilizing the same prices in the Company’s year-end reserve report), attributable to reserves subject to participation interests, overriding royalty interests or other
interests of third parties, pursuant to participation, partnership, vendor financing or other agreements then in effect, or which otherwise are required to be delivered to third parties; 
 (d) to the extent included in clause (1)(a) above, the discounted future net revenue calculated in accordance with SEC guidelines
(utilizing the same prices utilized in the Company’s year-end reserve report), attributable to reserves that are required to be delivered to third parties to fully satisfy the obligations of the Company and its Restricted Subsidiaries with
respect to Volumetric Production Payments on the schedules specified with respect thereto; and 
 (e) the discounted future
net revenue, calculated in accordance with SEC guidelines, attributable to reserves subject to Dollar-Denominated Production Payments that, based on the estimates of production included in determining the discounted future net revenue specified in
the immediately preceding clause (i)(a) (utilizing the same prices utilized in the Company’s year-end reserve report), would be necessary to satisfy fully the obligations of the Company and its Restricted Subsidiaries with respect to
Dollar-Denominated Production Payments on the schedules specified with respect thereto. 
 If the Company changes its method of accounting
from the full cost method to the successful efforts method or a similar method of accounting, “Adjusted Consolidated Net Tangible Assets” will continue to be calculated as if the Company were still using the full cost method of accounting.

with any cash) to be received by the Company or such Restricted Subsidiary, and provided further that any net cash received must be applied in accordance with the provisions described in Section 4.10;

 Section 2.01 Form and Dating. 
 (a) General. The Notes and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A hereto. The Notes may
have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be in denominations of $1,000 and integral multiples thereof. 
 The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and the Company, the Guarantors
and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the
provisions of this Indenture shall govern and be controlling. 
 (b) Global Notes. Notes issued in global form will be substantially
in the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in the form of Exhibit A
hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent such of the outstanding Notes as will be specified therein and
each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or
increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the
Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof. 
 Section 2.02 Execution and Authentication. 
 At least one Officer must sign the Notes for the Company by manual
or facsimile signature. 
 If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the
Note will nevertheless be valid. 
 A Note will not be valid until authenticated by the manual signature of the Trustee. The signature will
be conclusive evidence that the Note has been authenticated under this Indenture. 
 The Trustee will, upon receipt of a written order of the
Company signed by at least one Officer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The aggregate principal amount of Notes
outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof. 
 The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever
the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company.

 Section 2.03 Registrar and Paying Agent. 
 The Company will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and
an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more
additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The
Company will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any
of its Subsidiaries may act as Paying Agent or Registrar. 
 The Company initially appoints The Depository Trust Company
(“DTC”) to act as Depositary with respect to the Global Notes. 
 The Company initially appoints the Trustee to act as the
Registrar and Paying Agent and to act as Custodian with respect to the Global Notes. The place of payment with respect to the Notes, in addition to the Corporate Trust Office of the Trustee, shall be New York, New York, and at such time, if ever, as
the Notes are no longer represented by one or more Global Notes, the Company shall appoint and maintain a Paying Agent in the Borough of Manhattan, the City of New York, the intention of the Company being that, after giving effect to the procedures
of the Depositary respecting payments on Global Notes, the Notes shall at all times be payable in New York, New York. 
 The immunities,
protections and exculpations available to the Trustee under this Indenture shall also be available to each Agent, and the Company’s obligations under Section 7.7 to compensate and indemnify the Trustee shall extend likewise to each Agent.

 Section 2.04 Paying Agent to Hold Money in Trust. 
 The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the
payment of principal, premium, if any, or interest on the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by
it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) will have no further liability for the
money. If the Company or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the
Company, the Trustee will serve as Paying Agent for the Notes. 
 Section 2.05 Holder Lists. 
 The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders
and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company will furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee may request in
writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Company shall otherwise comply with TIA § 312(a).

 Section 2.06 Transfer and Exchange. 
 (a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary,
by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Company
for Definitive Notes if: 
 (1) the Company delivers to the Trustee notice from the Depositary that it is unwilling or unable
to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 120 days after the date of such notice from the
Depositary; 
 (2) the Company in its sole discretion determines that
the Global Notes (in whole but not in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee; or 
 (3) there has occurred and is continuing a Default or Event of Default with respect to the Notes. 
 Upon the
occurrence of any of the preceding events in (1), (2) or (3) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as
provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated
and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a), however, beneficial interests in a Global Note may be transferred and exchanged as
provided in Section 2.06(b) or (c) hereof. 
 (b) Transfer and Exchange of Beneficial Interests in the Global Notes. The
transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Beneficial interests in the Restricted Global Notes will be

Person or for the account or benefit of a U.S. Person (other than an Initial Purchaser). Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an
Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b)(1). 
 (2) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of
beneficial interests that are not subject to Section 2.06(b)(1) above, the transferor of such beneficial interest must deliver to the Registrar either:

RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE TRUSTEE. IF THE PROPOSED TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE AND THE COMPANY SUCH
CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE

 (g) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled
in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged
for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an
endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery
thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to
reflect such increase. 
 (h) General Provisions Relating to Transfers and Exchanges. 
 (1) To permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global Notes and
Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request. 
 (2) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may require payment of a sum
sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10,
4.14 and 9.05 hereof). 
 (3) The Registrar will not be required to register the transfer of or exchange of any Note selected
for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 
 (4) All Global Notes
and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the
Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 
 (5) Neither the Registrar nor
the Company will be required: 
 (A) to issue, to register the transfer of or to exchange any Notes during a period beginning
at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection; 
 (B) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any
Note being redeemed in part; or 
  

 41 

 (C) to register the transfer of or to exchange a Note between a record date and the next
succeeding interest payment date. 
 (6) Prior to due presentment for the registration of a transfer of any Note, the Trustee,
any Agent, the Company and the Guarantors may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of, premium, if any, and interest on such Notes and for
all other purposes, and none of the Trustee, any Agent, or the Company and the Guarantors shall be affected by notice to the contrary. 
 (7) The Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof. 
 (8) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06
to effect a registration of transfer or exchange may be submitted by facsimile. 
 Section 2.07 Replacement Notes. 
 If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Note, the Company will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company, an indemnity bond must be
supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Guarantors, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The
Company may charge for its expenses in replacing a Note. 
 Every replacement Note is an additional obligation of the Company and will be
entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. 
 Section 2.08
Outstanding Notes. 
 The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it,
those delivered to it for cancellation, those reductions in the interests in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in
Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 
 If a
Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. 
 If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

 If the Paying Agent (other than the Company or a Subsidiary thereof) holds, by 11:00 a.m. Eastern time on a redemption date or other
maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest. 
  

 42 

 Section 2.09 Treasury Notes. 
 In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the
Company or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Guarantor, will be considered as though not outstanding, except that for the purposes
of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded. 
 Section 2.10 Temporary Notes. 
 Until certificates representing Notes are ready for
delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Company considers
appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes. 
 Holders of temporary Notes will be entitled to all of the benefits of this Indenture. 
 Section 2.11 Cancellation. 
 The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer,
exchange, payment, replacement or cancellation and will destroy canceled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes will be delivered to the Company. The Company
may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. 
 Section 2.12
Defaulted Interest. 
 If the Company defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful
manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company will
notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company will fix or cause to be fixed each such special record date and payment date; provided that
no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name
and at the expense of the Company) will mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 
 ARTICLE 3

 If the
Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it must furnish to the Trustee, at least 30 days but not more than 60 days before a redemption date, an Officers’ Certificate setting
forth: 
 (1) the paragraph of Section 3.07 hereof pursuant to which the redemption shall occur; 
  

 43 

 (2) the redemption date; 
 (3) the principal amount of Notes to be redeemed; and 
 (4) the redemption price (if then determined and otherwise the basis for its determination). 
 Section 3.02 Selection of Notes to Be Redeemed or Purchased. 
 If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption on a pro rata basis unless otherwise required by law or applicable stock exchange requirements.

 In the event of partial redemption, the particular Notes to be redeemed or purchased will be selected, unless otherwise provided herein,
not less than 30 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption. 
 The Trustee will promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected
will be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as
provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. 
 Section 3.03 Notice of Redemption. 
 Subject to the provisions of Section 3.09 hereof, at least 30 days but
not more than 60 days before a redemption date, the Company will mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be
mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 11 hereof. 
 The notice will identify the Notes to be redeemed and will state: 
 (1) the redemption date; 
 (2) the redemption price (if then determined and otherwise the basis for its determination); 
 (3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed
portion will be issued upon cancellation of the original Note; 
 (4) the name and address of the Paying Agent; 
  

 44 

 (5) that Notes called for redemption must be surrendered to the Paying Agent to collect
the redemption price; 
 (6) that, unless the Company defaults in making such redemption payment, interest on Notes called for
redemption ceases to accrue on and after the redemption date; 
 (7) the paragraph in Section 3.07 of this Indenture
pursuant to which the Notes called for redemption are being redeemed; and 
 (8) that no representation is made as to the
correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. 
 At the Company’s request, the
Trustee will give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least five Business Days prior to the giving of such notice of redemption, an
Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 
 Section 3.04 Effect of Notice of Redemption. 
 Once notice of redemption is mailed in
accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional. 
 Section 3.05 Deposit of Redemption or Purchase Price. 
 By 11:00 a.m. Eastern time on the redemption or purchase date, the Company will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued interest on all
Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or
purchase price of, and accrued interest on, all Notes to be redeemed or purchased. 
 If the Company complies with the provisions of the
preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or tendered for purchase. If a Note is redeemed or purchased on or after an interest record
date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or
tendered for purchase is not so paid upon surrender for redemption or purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or tendered for purchase
date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 
 Section 3.06 Notes Redeemed or Purchased in Part. 
 Upon surrender of a Note that is redeemed or purchased in part, the Company will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Company a new Note equal in principal
amount to the unredeemed or unpurchased portion of the Note surrendered.

 Section 3.08 Mandatory Redemption. 
 The Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes. 
 Section 3.09 Offer to Purchase by Application of Excess Proceeds. 
 In the event that, pursuant to Section 4.10 hereof, the Company is required to commence an offer to all Holders to purchase Notes (an “Asset Sale Offer”), it will follow the procedures specified
below. 
 The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes
containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its
commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the
“Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than
the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made. 
 If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be
paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer. 
 Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, a notice to the Trustee and each of the Holders, with a copy to
the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

Asset Sale Offer will remain open; 
 (2) the Offer Amount, the purchase price and the Purchase Date; 
 (3) that any Note not tendered or accepted for payment will continue to accrue interest; 
 (4) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to
accrue interest after the Purchase Date; 
 (5) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer
may elect to have Notes purchased in integral multiples of $1,000 only; 
 (6) that Holders electing to have Notes purchased
pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a depositary, if
appointed by the Company, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date; 
  

 47 

 (7) that Holders will be entitled to withdraw their election if the Company, the
depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder
delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; 
 (8) that,
if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by Holders thereof exceeds the Offer Amount, the Trustee will select the Notes and other pari passu Indebtedness to be purchased on a pro
rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $1,000, or integral multiples
thereof, will be purchased); and 
 (9) that Holders whose Notes were purchased only in part will be issued new Notes equal in
principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer). 
 On or before the Purchase
Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been
tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in
accordance with the terms of this Section 3.09. The Company, the depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an
amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will authenticate and mail or
deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the
Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on the Purchase Date. 
 Other than as specifically
provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the applicable provisions of Sections 3.01 through 3.06 hereof.

 COVENANTS 
 Section 4.01 Payment of Notes. 
 The Company will pay or cause to be paid the principal
of, premium, if any, and interest on, the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest will be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary

 The Company will maintain in the continental United States, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee or
Registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such office or agency. If at any time the Company fails to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 
 The Company may also from time to time
designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission will
in any manner relieve the Company of its obligation under Section 2.03 to maintain an office or agency in the Borough of Manhattan, the City of New York where any Definitive Notes may be presented or surrendered for any payment. The Company
will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 
 The Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03 hereof. In case the Company shall fail to maintain any such

and the Company hereby appoints the Trustee its agent to receive at the aforesaid office all such surrenders, presentations, notices and demands. 
 Section 4.03 Reports.

 (2) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were
required to file such reports.

action for the purpose of causing the SEC not to accept any such filings. If, notwithstanding the foregoing, the SEC will not accept the Company’s filings for any reason, the Company will post the reports referred to in the preceding paragraph
on its website within 30 days of the time periods that would apply if the Company were required to file those reports with the SEC.

 Section 4.06 Stay, Extension and Usury Laws. 
 The Company and each of the Guarantors 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 wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company and each of
the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted
to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

 which amount in each case under this clause (C) was
included in the calculation of the amount of Restricted Payments; provided, however, that no amount will be included under this clause (C) to the extent it is already included in Consolidated Net Income; plus 
 (D) 50% of any dividends received by the Company or a Restricted Subsidiary of the Company that is a Guarantor after the Issue Date from
an Unrestricted Subsidiary of the Company, to the extent that such dividends were not otherwise included in the Consolidated Net Income of the Company for such period.

 (a) in the case of a Change of Control, the Company has first complied with and fully satisfied its obligations under Section 4.14 (including without limitation the repurchase of all Notes validly tendered for payment in connection
therewith); or

Such Officers’ Certificate shall state that the Restricted Payment is permitted by this Section 4.07. For purposes of determining compliance with this Section 4.07, in the event that a Restricted Payment meets the criteria of more
than one of the exceptions described in (1) through (11) above or is entitled to be made pursuant to the first paragraph of this Section 4.07, the Company shall, in its sole discretion, classify such Restricted Payment, or later
classify, reclassify or re-divide all or a portion of such Restricted Payment, in any manner that complies with this Section 4.07. 
 Section 4.08 Dividend and Other Payment Restrictions Affecting Subsidiaries. 
 (a) The Company will not, and will
not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

 (1) agreements governing Existing Indebtedness and Credit Facilities as in effect on the Issue Date and any amendments,
restatements, modifications, renewals, supplements, increases, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications, renewals, supplements, increases, refundings, replacements
or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment encumbrances or restrictions than those contained in those agreements on the Issue Date; 
 (2) this Indenture, the Notes and the Note Guarantees; 
 (3) applicable law, rule, regulation, order, approval, permit or similar restriction; 
 (4) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in

properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

 (5) customary non-assignment provisions in contracts, leases and licenses (including, without limitation, licenses of
intellectual property) entered into in the ordinary course of business;

 55 

 (10) other Indebtedness of the Company or any of its Restricted Subsidiaries permitted to
be incurred pursuant to an agreement entered into subsequent to the Issue Date in accordance with Section 4.09; provided that the provisions of such agreement relating to such dividend and other payment encumbrances or restrictions taken as a
whole are not materially more restrictive, as determined by the Board of Directors or the Company in good faith, than those provisions contained in the agreements governing Existing Indebtedness and the Credit Agreement, in each case as in effect on
the Issue Date; 
 (11) the issuance of preferred stock by a Restricted Subsidiary or the payment of dividends thereon in
accordance with Section 4.09 and the terms thereof; provided that issuance of such preferred stock was made in accordance and the terms of such preferred stock do not expressly restrict the ability of a Restricted Subsidiary to pay dividends or
make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such preferred stock prior to paying any dividends or making any other distributions on such other Capital Stock);

 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or
otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Company will not issue any Disqualified Stock and will not permit
any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company and the Restricted Subsidiaries may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock or preferred
stock of a Restricted Subsidiary, if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional
Indebtedness is incurred or such Disqualified Stock or preferred stock of a Restricted Subsidiary is issued, as the case may be, would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net
proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter period. 
 (b) The provisions of Section 4.09(a) hereof will not prohibit the incurrence of any of the following items of Indebtedness (collectively,
“Permitted Debt”): 
 (1) the incurrence by the Company and any Restricted Subsidiary of Indebtedness
(including letters of credit) under Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of
the Company and its Restricted Subsidiaries thereunder) not to exceed the greater of (a) $800.0 million and (b) an amount equal to the sum of (A) $600.0 million plus (B) 10% of Adjusted Consolidated Net Tangible Assets determined
as of the date of the incurrence of such Indebtedness after giving pro forma effect to such incurrence and the application of the proceeds therefrom; 
  

 56 

 (2) the incurrence by the Company and its Restricted Subsidiaries of the Existing
Indebtedness; 
 (3) the incurrence by the Company and the Guarantors of Indebtedness represented by the Notes and the related

 (4) the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or
improvement of property, plant or equipment used in the business of the Company or any of its Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace,
defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed $50.0 million at any time outstanding; 
 (5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness
(other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under Section 4.09(a) hereof or clauses (2), (3), (4) or (11) of this Section 4.09(b) or this clause (5); 
 (6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any
of its Restricted Subsidiaries; provided, however, that: 
 (A) if the Company or any Guarantor is the obligor on such
Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of the Company, or the Note
Guarantee, in the case of a Guarantor; and 
 (B) (i) any subsequent issuance or transfer of Equity Interests that
results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted
Subsidiary of the Company will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); 
 (7) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of shares of
preferred stock; provided, however, that: 
 (A) any subsequent issuance or transfer of Equity Interests that results in any
such preferred stock being held by a Person other than the Company or a Restricted Subsidiary of the Company; and 
  

 57 

 (B) any sale or other transfer of any such preferred stock to a Person that is not either
the Company or a Restricted Subsidiary of the Company, 
 will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted
Subsidiary that was not permitted by this clause (7); 
 (8) the incurrence by the Company or any of its Restricted
Subsidiaries of Hedging Obligations in the ordinary course of business; 
 (9) the incurrence by the Company of any of its
Restricted Subsidiaries of obligations relating to net gas balancing positions arising in the ordinary course of business and consistent with past practice; 
 (10) the Guarantee by the Company or any of the Guarantors of Indebtedness of the Company or a Restricted Subsidiary of the Company that
was permitted to be incurred by another provision of this Section 4.09; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the Guarantee shall be subordinated or pari passu, as applicable,
to the same extent as the Indebtedness guaranteed; 
 (11) Permitted Acquisition Indebtedness; 
 (12) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other
financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days; 
 (13) Indebtedness consisting of the financing of insurance premiums in customary amounts consistent with the operations and business of
the Company and its Restricted Subsidiaries; 
 (14) the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness arising from agreements of the Company or any of its Restricted Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any
business, assets or Capital Stock of a Subsidiary, provided that the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds actually received by the Company and its Restricted Subsidiaries in
connection with such disposition; 
 (15) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness
in respect of bid, performance, surety and similar bonds issued for the account of the Company and any of its Restricted Subsidiaries in the ordinary course of business, including guarantees and obligations of the Company or any of its Restricted
Subsidiaries with respect to letters of credit supporting such obligations (in each case, other than an obligation for money borrowed); and 
 (16) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding not to exceed $100.0
million. 
  

 58 

 (c) The Company will not incur, and will not permit any Guarantor to incur, any Indebtedness (including
Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Note
Guarantee on substantially identical terms; provided, however, that no Indebtedness shall be deemed to be contractually subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured or by virtue of being
secured on a first or junior Lien basis. 
 (d) For purposes of determining compliance with this Section 4.09, in the event that an item
of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (16) above or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company will be
permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. The accrual of interest, the accretion or
amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of
Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.09; provided, in each such case, that the amount thereof is included in Fixed Charges of the
Company as accrued. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to be exceeded
solely as a result of fluctuations in exchange rates or currency values. 
 (e) The amount of any Indebtedness outstanding as of any date
will be: 
 (1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

 (2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and 
 (3) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of: 
 (A) the Fair Market Value of such asset at such date of determination; and 
 (B) the amount of the Indebtedness of the other Person. 
 Section 4.10 Asset Sales. 
 (a) The Company will not, and will not permit any of its
Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (1) the Company (or the Restricted Subsidiary, as the case may
be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the Equity Interests or other assets issued or sold or otherwise disposed of; and 
 (2)(a) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or
(b) the Fair Market Value of all forms of consideration other than cash received for all Asset Sales since the Issue Date does not exceed in the aggregate 10% of the Adjusted Consolidated Net Tangible Assets of the Company at the time each
determination is made. For purposes of this provision, each of the following shall be deemed to be cash: 
 (A) any
liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and Subordinated Obligations) that are assumed by the transferee of any such assets
pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability; 
  

 59 

 (B) any securities, notes or other obligations received by the Company or any such
Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 180 days after the date of the Asset Sale, to the extent of the cash received in that conversion; 
 (C) any stock or assets of the kind referred to in clauses (2) or (3) of the next paragraph of this Section 4.10; and

 (D) accounts receivable of a business retained by the Company or any Restricted Subsidiary, as the case may be, following
the sale of such business; provided that such accounts receivable are not (i) past due more than 90 days and (ii) do not have a payment date greater than 120 days from the date of the invoice creating such accounts receivable.

 (b) Within 360 days after the receipt of any Net Proceeds from an Asset Sale, or, if the Company has entered into a binding commitment or
commitments with respect to the actions described in clause (2) or (3) below, within 540 days after the receipt of any Net Proceeds from an Asset Sale, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply
such Net Proceeds: 
 (1) to repay, prepay, redeem or repurchase Senior Debt; 
 (2) invest in Additional Assets; 
 (3) to make capital expenditures in respect of the Company’s or its Restricted Subsidiaries’ Oil and Gas Business; or 
 (4) any combination of the foregoing. 
 Pending the application of any Net Proceeds in the manner provided above, the Company or any Restricted Subsidiary may invest the Net Proceeds in any manner that is not prohibited by this Indenture. 
 (c) Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.10(b) will constitute “Excess
Proceeds.” Within five days after the date that the aggregate amount of Excess Proceeds exceeds $20.0 million, the Company will make an Asset Sale Offer to all Holders of Notes and all holders of other Indebtedness that is pari passu
with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets in accordance with Section 3.09 hereof to purchase the maximum principal amount
of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest to, but excluding, the
date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal
amount of 

  

 60 

 
Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes
and such other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
 (d) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of Section 3.09
hereof or this Section 4.10, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 hereof or this Section 4.10 by virtue of such
compliance. 
 Section 4.11 Transactions with Affiliates. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property
or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each an “Affiliate Transaction”), unless:

 (1) the Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary
than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and 
 (2) the Company delivers to the Trustee: 
 (A) with respect to any Affiliate Transaction or
series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that such Affiliate Transaction
complies with clause (1) of this Section 4.11(a) and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of the Company; and 
 (B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of
$30.0 million, an opinion as to the fairness to the Company or such Restricted Subsidiary of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. 
 (b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.11(a)
hereof: 
 (1) any employment agreement or arrangement, stock option or stock ownership plan, employee benefit plan, officer
or director indemnification agreement, restricted stock agreement, severance agreement or other compensation plan or arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments,
awards, grants or issuances of securities pursuant thereto, including, without limitation, pursuant to the Company’s Long-Term Incentive Compensation Plan, as amended; 
 (2) transactions between or among the Company and/or its Restricted Subsidiaries; 
  

 61 

 (3) transactions with a Person (other than an Unrestricted Subsidiary of the Company)
that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person; 
 (4) reasonable fees and expenses and compensation paid to, and indemnity or insurance provided on behalf of, officers, directors or
employees of the Company or any Restricted Subsidiaries as determined in good faith by the Board of Directors; 
 (5) any
issuance of Equity Interests (other than Disqualified Stock) of the Company to, or receipt by the Company of a capital contribution from, Affiliates (or a Person that becomes an Affiliate) of the Company; 
 (6) Restricted Payments that do not violate Section 4.07 hereof; 
 (7) transactions between the Company or any Restricted Subsidiaries and any Person, a director of which is also a director of the Company
or any direct or indirect parent company of the Company and such director is the sole cause for such Person to be deemed an Affiliate of the Company or any Restricted Subsidiaries; provided, however, that such director abstains from
voting as director of the Company or such direct or indirect parent company, as the case may be, on any matter involving such other Person; 
 (8) loans or advances to employees in the ordinary course of business or consistent with past practice not to exceed $5.0 million in the aggregate at any one time outstanding;

 (10) any transaction in which the Company or any of its Restricted Subsidiaries, as the
case may be, deliver to the Trustee a letter from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view or that such
transaction meets the requirements of clause (1) of Section 4.11(a); 
 (11) the performance of obligations of the
Company or any of its Restricted Subsidiaries under the terms of any written agreement to which the Company or any of its Restricted Subsidiaries is a party on the Issue Date and which is described in the Company’s offering memorandum relating
to the Initial Notes, as these agreements may be amended, modified or supplemented from time to time; provided, however, that any future amendment, modification or supplement entered into after the Issue Date will be permitted to the extent that its
terms do not materially and adversely affect the rights of any Holders of the Notes (as determined in good faith by the Board of Directors of the Company) as compared to the terms of the agreements in effect on the Issue Date; and 
 (12)(a) guarantees of performance by the Company and its Restricted Subsidiaries of the Company’s Unrestricted Subsidiaries in the

 Section 4.12 Liens. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien (other than Permitted Liens) upon any of its property or
assets (whether now owned or hereafter acquired), securing any Subordinated Obligations or other Indebtedness, unless: 
 (1)
in the case of any Lien securing Subordinated Obligations of the Company or a Guarantor, the Notes or Note Guarantee, as applicable, are secured by a Lien on such property or assets on a senior basis to the Subordinated Obligations so secured until
such time as such Subordinated Obligations are no longer so secured by that Lien; and 
 (2) in the case of any other Lien
(other than a Permitted Lien) securing other Indebtedness, the Notes or Note Guarantees, as applicable, are secured by a Lien on such property or assets on an equal and ratable basis with the Indebtedness so secured until such time as such
Indebtedness is no longer so secured by that Lien. 
 Section 4.13 Corporate Existence. 
 Subject to Article 5 hereof, so long as any of the Notes shall remain outstanding, the Company will at all times do or cause to be done all things
necessary to preserve and keep in full force and effect its corporate existence. 
 Section 4.14 Offer to Repurchase Upon Change of Control.

 (a) Upon the occurrence of a Change of Control, each Holder of the Notes will have the right to require the Company to make an offer (a
“Change of Control Offer”) to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes
repurchased plus accrued and unpaid interest, if any, on the Notes repurchased to the date of purchase, subject to the rights of Holders on an record date to receive interest due on the relevant interest payment date (the “Change of Control
Payment”). Within thirty days following any Change of Control, the Company will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating: 
 (1) that the Change of Control Offer is being made pursuant to this Section 4.14 and that all Notes tendered will be accepted for
payment; 
 (2) the purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days
from the date such notice is mailed (the “Change of Control Payment Date”); 
 (3) that any Note not tendered
will continue to accrue interest; 
 (4) that, unless the Company defaults in the payment of the Change of Control Payment,
all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 
 (5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to
the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date; 
  

 63 

 (6) that Holders will be entitled to withdraw their election if the Paying Agent
receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered
for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and 
 (7) that
Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $1,000 in principal amount or an integral
multiple thereof. 
 (b) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and
regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change in Control. To the extent that the provisions of any securities laws or regulations conflict with
the provisions of Section 4.14 hereof, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 hereof or this Section 4.14 by virtue of
such compliance. 
 (c) On the Change of Control Payment Date, the Company will, to the extent lawful: 
 (1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 
 (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly
tendered; and 
 (3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an
Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 
 The Paying
Agent will promptly mail (but in any case not later than five days after the Change of Control Payment Date) to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail
(or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note will be in a principal amount of $1,000 or an
integral multiple thereof. Any Note so accepted for payment will cease to accrue interest on and after the Change of Control Payment Date unless the Company defaults in making the Change of Control Payment. The Company will publicly announce the
results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 
 (d) Notwithstanding anything
to the contrary in this Section 4.14, the Company will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in
compliance with the requirements set forth in this Section 4.14 and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 3.07 hereof,
unless and until there is a default in payment of the applicable redemption price. 
  

 64 

 (e) A Change of Control Offer may be made in advance of a Change of Control, and conditioned upon the
occurrence of such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer. 
 (f) Notes repurchased by the Company pursuant to a Change of Control Offer will have the status of Notes issued but not outstanding or will be retired and cancelled, at the Company’s option. Notes purchased by a
third party pursuant to the preceding paragraph will have the status of Notes issued and outstanding. 
 (g) The provisions described above
that require the Company to make a Change of Control Offer following a Change of Control will be applicable regardless of whether or not any other provisions of this Indenture are applicable. 
 Section 4.15 Payments for Consent. 
 The
Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment
of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents
relating to such consent, waiver or agreement. 
 Section 4.16 Additional Note Guarantees. 
 If, after the Issue Date, any Domestic Subsidiary that is not already a Guarantor has Indebtedness outstanding in excess of a Minimum Amount or guarantees
any other Indebtedness of the Company or of a Guarantor in excess of a Minimum Amount, then such Domestic Subsidiary will become a Guarantor with respect to the Notes issued hereunder by executing and delivering a supplemental indenture, in the form
attached as Exhibit F to this Indenture, to the Trustee within 180 days of the date on which it guaranteed such Indebtedness. The form of such supplemental indenture is attached as Exhibit F hereto. 
 Section 4.17 Designation of Restricted and Unrestricted Subsidiaries. 
 The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted
Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as Unrestricted will be deemed to be an Investment made as of the time of the designation
and will reduce the amount available for Restricted Payments under Section 4.07 hereof or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the
Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. 
 Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an
Officers’ Certificate certifying that such designation complied with the preceding conditions of this Section 4.17 and was permitted by Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding
requirements of this Section 4.17 as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted
Subsidiary of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of 

  

 65 

 
such date under Section 4.09 hereof, the Company will be in default of such covenant. The Board of Directors of the Company may at any time designate
any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted
Subsidiary and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference
period and (2) no Default or Event of Default would be in existence immediately following such designation.

Person, unless: 
 (1) either: 
 (A) the Company is the surviving corporation; or 
 (B) the Person formed by or surviving any
such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, conveyance or other disposition has been made is a corporation, limited liability company or limited partnership organized or existing under the

 (2) the Person formed by or
surviving any such consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, conveyance or other disposition has been made assumes all the obligations of the Company under the Notes and this
Indenture and pursuant to agreements reasonably satisfactory to the Trustee; provided that, unless such Person is a corporation, a corporate co-issuer of the Notes will be added to this Indenture by agreements reasonably satisfactory to the
Trustee. 
 (3) immediately after such transaction or transactions, no Default or Event of Default exists; and 
 (4) the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale,
assignment, transfer, conveyance or other disposition has been made, would, on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of the applicable
four-quarter period, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.09(a) hereof. 
 For purposes of this Section 5.01, the sale, lease, conveyance, assignment, transfer, or other disposition of all or substantially all of the
properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a
consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company. 
  

 66 

 Notwithstanding the restrictions described in clause (4) of this Section 5.01, any Restricted
Subsidiary may consolidate with, merge into or transfer all or part of its properties and assets to the Company, the Company may merge into a Restricted Subsidiary for the purpose of reincorporating the Company in another jurisdiction, and any
Restricted Subsidiary may consolidate with, merge into or transfer all or part of its properties and assets to another Restricted Subsidiary. 
 Section 5.02 Successor Corporation Substituted. 
 Upon any consolidation or merger, or any sale, assignment,
transfer, lease, conveyance or other disposition of all or substantially all of the properties and assets of the Company in a transaction that is subject to, and that complies with the provisions of, Section 5.01 hereof, the successor Person
formed by such consolidation or into or with which the Company is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such
consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition, the provisions of this Indenture referring to the “Company” shall refer instead to the successor Person and not to the Company), and may exercise
every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein; provided, however, that, in the case of a lease of all or substantially all of its properties and
assets, the Company will not be released from the obligation to pay the principal of and interest and premium, if any, on the Notes. 
 ARTICLE 6 
 DEFAULTS AND REMEDIES 
 Section 6.01 Events of Default. 
 Each of the following will be an “Event of Default”:

 (1) default for 30 days in the payment when due of interest on the Notes; 
 (2) default in the payment when due (at maturity, upon redemption or otherwise) of the principal of, or premium, if any, on, the Notes;

 (3) failure by the Company or any of its Restricted Subsidiaries to comply with the provisions of Sections 4.10, 4.14 or
5.01 hereof; 
 (4) failure by the Company or any of its Restricted Subsidiaries for 60 days after notice to the Company by
the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class to comply with any of the other agreements in this Indenture; 
 (5) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after
the Issue Date, if that default: 
 (A) is caused by a failure to pay principal of, or interest or premium, if any, on, such
Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or 
  

 67 

 (B) results in the acceleration of such Indebtedness prior to its express maturity,

 and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under
which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $20.0 million or more; provided that if any such default is cured or waived or any such acceleration rescinded, or such Indebtedness is
repaid, within a period of 15 Business 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 and any consequential acceleration of the Notes
shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree; 
 (6) failure by
the Company or any of its Restricted Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $20.0 million (net of any amount with respect to which a reputable and solvent insurance company
has acknowledged liability in writing), which judgments are not paid, discharged, stayed or fully bonded for a period of 60 days (or, if later, the date when payment is due pursuant to such judgment); 
 (7) the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the
Company that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law: 
 (A) commences a voluntary case, 
 (B) consents to the entry of an order for relief against it in an involuntary
case, 
 (C) consents to the appointment of a custodian of it or for all or substantially all of its property, 
 (D) makes a general assignment for the benefit of its creditors, or 
 (E) generally is not paying its debts as they become due; 
 (8) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 
 (A) is for relief against the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted
Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary in an involuntary case; 
 (B)
appoints a custodian of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary or for all or
substantially all of the property of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; or

  

 68 

 (C) orders the liquidation of the Company or any of its Restricted Subsidiaries that is a
Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; 
 and the order or decree remains unstayed and in effect for 60 consecutive days; and 
 (9)(a) except as permitted by
this Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or (b) any Guarantor, or any Person acting on behalf of any Guarantor, denies or
disaffirms its obligations under its Note Guarantee. 
 Section 6.02 Acceleration. 
 In the case of an Event of Default specified in clause (7) or (8) of Section 6.01 hereof, with respect to the Company, any Restricted
Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without
further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all of the Notes to be due and payable immediately
by notice in writing to the Company and, in the case of notice by Holders, also to the Trustee specifying the applicable Events of Default and that it is a notice of acceleration. 
 Upon any such declaration, the Notes shall become due and payable immediately. 
 The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the
Holders, rescind an acceleration and its consequences, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium that has become due solely because of
the acceleration) have been cured or waived. 
 Section 6.03 Other Remedies. 
 If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and
interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
 The Trustee may maintain a proceeding
even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right
or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 
 Section 6.04 Waiver of Past Defaults. 
 Holders of not less than a majority in aggregate principal amount of the
then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the
principal of, premium, if any, or interest on, the Notes (including in connection with an offer to purchase). Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for
every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 
  

 69 

 Section 6.05 Control by Majority. 
 Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial
to the rights of other Holders of Notes or that may involve the Trustee in personal liability. 
 Section 6.06 Limitation on Suits.

 A Holder may pursue a remedy with respect to this Indenture or the Notes only if: 
 (1) such Holder gives to the Trustee written notice that an Event of Default is continuing; 
 (2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue
the remedy; 
 (3) such Holder or Holders offer and, if requested, provide to the Trustee security or indemnity reasonably
satisfactory to the Trustee against any loss, liability or expense; 
 (4) the Trustee does not comply with the request within
60 days after receipt of the request and the offer of security or indemnity; and 
 (5) during such 60-day period, Holders of
a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request. 
 A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. 
 Section 6.07 Rights of Holders of Notes to Receive Payment. 
 Notwithstanding any other
provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to
purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 
 Section 6.08 Collection Suit by Trustee. 
 If an Event of Default specified in
Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium, if any, and
interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest and 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. 
 Section 6.09 Trustee May File Proofs of Claim. 

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of
the Trustee (including any claim for the reasonable 

  

 70 

 
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings
relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any
custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any
amount due 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 7.07 hereof. To the extent that the payment of any such
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the
same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of
reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 6.10 Priorities. 
 If the Trustee collects any money pursuant to this Article 6, it shall pay out the
money in the following order: 
 First: to the Trustee, its agents and attorneys for amounts due under
Section 7.07 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 
 Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without
preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any and interest, respectively; and 
 Third: to the Company or to such party as a court of competent jurisdiction shall direct. 
 The
Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. 
 Section 6.11
Undertaking for Costs. 
 In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a
suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

 ARTICLE 7 
 TRUSTEE 
 Section 7.01 Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested in it by this Indenture, and use
the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 
 (b) Except during the continuance of an Event of Default: 
 (1) the duties of the Trustee
will be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this
Indenture against the Trustee; and 
 (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee will examine the certificates and
opinions to determine whether or not they conform to the requirements of this Indenture. 
 (c) The Trustee may not be relieved from
liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 
 (1)
this paragraph does not limit the effect of paragraph (b) of this Section 7.01; 
 (2) the Trustee will not be
liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (3) the Trustee will not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction
received by it pursuant to Section 6.05 hereof.

that in any way relates to the Trustee is subject to paragraphs (a), (b), and (c) of this Section 7.01. 
 (e) No provision of this
Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holder has
offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense. 
 (f) The Trustee will not be
liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 
  

 72 

 Section 7.02 Rights of Trustee. 
 (a) The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The
Trustee need not investigate any fact or matter stated in the document. 
 (b) Before the Trustee acts or refrains from acting, it may
require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may
consult with counsel and the written advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon. 
 (c) The Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of
any agent appointed with due care. 
 (d) The Trustee will not be liable for any action it takes or omits to take in good faith that it
believes to be authorized or within the rights or powers conferred upon it by this Indenture. 
 (e) Unless otherwise specifically provided
in this Indenture, any demand, request, direction or notice from the Company will be sufficient if signed by an Officer of the Company. 
 (f) The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee reasonable indemnity or
security against the losses, liabilities and expenses that might be incurred by it in compliance with such request or direction. 
 Section 7.03 Individual Rights of Trustee. 
 The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate
such conflict within 90 days, apply to the SEC for permission to continue as trustee (if this Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10

responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. 
 Section 7.05 Notice of Defaults. 
 If a
Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee will mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of

 73 

 
or interest on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that
withholding the notice is in the interests of the Holders of the Notes. 
 Section 7.06 Reports by Trustee to Holders of the Notes.

 (a) Within 60 days after each May 15 beginning with the May 15 following the Issue Date, and for so long as Notes remain
outstanding, the Trustee will mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months
preceding the reporting date, no report need be transmitted). The Trustee also will comply with TIA § 313(b)(2). The Trustee will also transmit by mail all reports as required by TIA § 313(c). 
 (b) A copy of each report at the time of its mailing to the Holders of Notes will be mailed by the Trustee to the Company and filed by the Trustee with
the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Company will promptly notify the Trustee when the Notes are listed on any stock exchange. 
 Section 7.07 Compensation and Indemnity. 
 (a) The Company will pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an

compensation, disbursements and expenses of the Trustee’s agents and counsel. 
 (b) The Company and the Guarantors will indemnify the
Trustee against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against

any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or bad faith. The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by
the Trustee to so notify the Company will not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have
separate counsel and the Company will pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien will survive the satisfaction and discharge of this Indenture. 
 (e) When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(7) or (8) hereof occurs, the
expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

 (2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy
Law; 
 (3) a custodian or public officer takes charge of the Trustee or its property; or 
 (4) the Trustee becomes incapable of acting. 
 (c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company will promptly appoint a successor Trustee. Within one year after the successor Trustee takes office,
the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. 
 (d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or

have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will mail a notice of its succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor
Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s
obligations under Section 7.07 hereof will continue for the benefit of the retiring Trustee. 
  

 75 

 Section 7.09 Successor Trustee by Merger, etc.

successor corporation without any further act will be the successor Trustee.

 ARTICLE 8 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance. 
 The Company may
at any time, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions
set forth below in this Article 8. 
 Section 8.02 Legal Defeasance and Discharge. 
 Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company and each of the Guarantors
will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set
forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and
(2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same),
except for the following provisions which will survive until otherwise terminated or discharged hereunder: 
 (1) the rights
of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium, if any, on, such Notes when such payments are due from the trust referred to in Section 8.04 hereof; 
  

 76 

 (2) the Company’s obligations with respect to such Notes under Article 2 and
Section 4.02 hereof; 
 (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the
Company’s and the Guarantors’ obligations in connection therewith; and 
 (4) this Article 8. 
 Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its
option under Section 8.03 hereof. 
 Section 8.03 Covenant Defeasance. 
 Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and each of the Guarantors
will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.03(b), 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16
and 4.17 hereof and clause (4) of Section 5.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and
the Notes will thereafter be deemed not “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 will continue to be
deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and
Note Guarantees, the Company and the Guarantors may omit to comply with and will 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 will not constitute a Default or an Event of Default under Section 6.01 hereof,
but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this
Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) through 6.01(6) hereof will not constitute Events of Default. 
 Section 8.04 Conditions to Legal or Covenant Defeasance. 
 In order to exercise either
Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof: 
 (1) the Company must irrevocably
deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of
independent public accountants, to pay the principal of, premium and interest on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes
are being defeased to such stated date for payment or to a particular redemption date; 
 (2) in the case of an election under
Section 8.02 hereof, the Company must deliver to the Trustee an Opinion of Counsel confirming that: 
 (A) the Company
has received from, or there has been published by, the Internal Revenue Service a ruling; or 
  

 77 

 (B) since the Issue Date, there has been a change in the applicable federal income tax
law, 
 in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes
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; 
 (3) in the case of an election under Section 8.03 hereof, the Company must deliver
to the Trustee an Opinion of Counsel confirming that the Holders of the outstanding Notes 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; 
 (4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not
result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound; 
 (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material
agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 
 (6) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the
intent of preferring the Holders of Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others; and 
 (7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 Section 8.05 Deposited Money and Government
Securities to be Held in Trust; Other Miscellaneous Provisions. 
 Subject to Section 8.06 hereof, all money and non-callable
Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of
the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as
the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

 The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or
non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the
outstanding Notes. 
  

 78 

 Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the
Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent
Legal Defeasance or Covenant Defeasance. 
 Section 8.06 Repayment to Company. 
 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, premium, if any, or
interest on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) will be discharged from such
trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee
thereof, will 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 the New York Times and The Wall Street
Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining
will be repaid to the Company. 
 Section 8.07 Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03
hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under this Indenture
and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance
with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on, any Note following the reinstatement of its obligations, the Company will
be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 
 ARTICLE 9 
 AMENDMENT, SUPPLEMENT AND WAIVER 
 Section 9.01 Without Consent of Holders of Notes. 
 Notwithstanding Section 9.02 of this Indenture, the
Company, the Guarantors and the Trustee may amend or supplement this Indenture or the Notes or the Note Guarantees without the consent of any Holder of Notes: 
 (1) to cure any ambiguity, defect or inconsistency; 
 (2) to provide for uncertificated Notes in addition to or in place of certificated Notes; 
  

 79 

 (3) to provide for the assumption of the Company’s or a Guarantor’s obligations
to the Holders of the Notes and Note Guarantees by a successor to the Company or such Guarantor pursuant to Article 5 or Article 10 hereof; 
 (4) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder; 
 (5) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; 

(6) to conform the text of this Indenture the Note Guarantees or the Notes to any provision of the “Description of Notes”
section of the Company’s Offering Memorandum dated June 8, 2007, relating to the initial offering of the Notes, to the extent that such provision in that “Description of Notes” was intended to be a verbatim recitation of a
provision of this Indenture, the Note Guarantees or the Notes; 
 (7) to provide for the issuance of Additional Notes in
accordance with the limitations set forth in this Indenture as of the date hereof; 
 (8) to allow any Guarantor to execute a
supplemental indenture and/or a Note Guarantee with respect to the Notes or release the Note Guarantees pursuant to the terms of this Indenture; 
 (9) to secure the Notes; or 
 (10) to evidence and provide for the acceptance under this
Indenture of a successor trustee. 
 Upon the request of the Company, and upon receipt by the Trustee of the documents described in
Section 7.02 hereof, the Trustee will join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 
 Section 9.02 With Consent of Holders of Notes. 
 Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including, without limitation, Sections 3.09, 4.10 and 4.14 hereof) and the Notes and the Note Guarantees with the
consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in
connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of,
premium, if any, or interest on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the
Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer
or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02. 
  

 80 

 Upon the request of the Company, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Company and the Guarantors in the execution of such amended or
supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated
to, enter into such amended or supplemental Indenture. 
 It is not be necessary for the consent of the Holders of Notes under this
Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof. 
 After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver.
Any failure of the Company to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Without the consent of each Holder affected, an amendment,
supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder): 
 (1)
reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 
 (2) reduce the
principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes (except as provided above with respect to Sections 3.09, 4.10 and 4.14 hereof); 
 (3) reduce the rate of or change the time for payment of interest, including default interest, on any Note; 
 (4) waive a Default or Event of Default in the payment of principal of, or premium, if any, or interest on, the Notes (except a rescission
of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration); 
 (5) make any Note payable in money other than that stated in the Notes; 
 (6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive
payments of principal of, or interest or premium, if any, on, the Notes; 
 (7) waive a redemption payment with respect to any
Note (other than a payment required by Sections 3.09, 4.10 or 4.14 hereof); 
 (8) release any Guarantor from any of its
obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; or 
 (9) make
any change in the preceding amendment and waiver provisions. 
  

 81 

 Section 9.03 Compliance with Trust Indenture Act. 
 Every amendment or supplement to this Indenture or the Notes will be set forth in a amended or supplemental indenture that complies with the TIA as then
in effect. 
 Section 9.04 Revocation and Effect of Consents. 
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may
revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder. 
 Section 9.05 Notation on or Exchange of Notes. 
 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for
all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. 
 Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver. 
 Section 9.06 Trustee to Sign Amendments, etc. 
 The Trustee will sign any amended or
supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amended or supplemental indenture until
the Board of Directors of the Company approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon an Officers’
Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture. 
 ARTICLE 10 
 NOTE GUARANTEES 
 Section 10.01 Guarantee. 
 (a) Subject to this Article 10, each of the Guarantors hereby,
jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or
the obligations of the Company hereunder or thereunder, that: 
 (1) the principal of, premium, if any, and interest on, the
Notes will be promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to
the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
  

 82 

 (2) in case of any extension of time of payment or renewal of any Notes or any of such
other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration, redemption or otherwise. 
 Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally
obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 
 (b)
The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any
Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or
defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company,
protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. 
 (c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or
other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

 (d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any
obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of
the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the
purpose of this Note Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee. 
 Section 10.02 Limitation on Guarantor Liability. 
 Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of
Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the
Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant
under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the
obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance. 
  

 83 

 Section 10.03 Execution and Delivery of Note Guarantee. 
 To evidence its Note Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially
in the form attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its Officers.

 Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 hereof will remain in full force and effect
notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. 
 If an Officer whose signature is on this Indenture
or on the Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless. 
 The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this
Indenture on behalf of the Guarantors. 
 In the event that the Company or any of its Restricted Subsidiaries creates or acquires any
Domestic Subsidiary after the Issue Date, if required by Section 4.16 hereof, the Company will cause such Domestic Subsidiary to comply with the provisions of Section 4.16 hereof and this Article 10, to the extent applicable. 

Section 10.04 Guarantors May Consolidate, etc., on Certain Terms. 
 Except as otherwise provided in Section 10.05 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such
Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless: 
 (1) immediately
after giving effect to such transaction, no Default or Event of Default exists; and 
 (2) either: 
 (a) subject to Section 10.05 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or
surviving any such consolidation or merger unconditionally assumes all the obligations of that Guarantor under this Indenture, its Note Guarantee on the terms set forth herein or therein, pursuant to a supplemental indenture in form and substance
reasonably satisfactory to the Trustee; or 
 (b) the Net Proceeds of such sale or other disposition are applied in accordance
with Section 4.10 hereof. 
 In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor
Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by
the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Note Guarantees to
be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Note Guarantees so issued will in all respects have the same legal 

  

 84 

 
rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all
of such Note Guarantees had been issued at the date of the execution hereof. 
 Except as set forth in Articles 4 and 5 hereof, and
notwithstanding clauses 2(a) and (b) above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance
of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor. 
 Section 10.05 Releases.

 (a) In the event of any sale or other disposition of all or substantially all of the assets of any Guarantor, by way of merger,
consolidation or otherwise, or a sale or other disposition of all of the Capital Stock of any Guarantor, in each case to a Person that is not (either before or after giving effect to such transactions) the Company or a Restricted Subsidiary of the
Company, then such Guarantor (in the event of a sale or other disposition, by way of merger, consolidation or otherwise, of all of the Capital Stock of such Guarantor) or the Person acquiring the property (in the event of a sale or other disposition
of all or substantially all of the assets of such Guarantor) will be released and relieved of any obligations under its Note Guarantee; provided that the Net Proceeds of such sale or other disposition are applied in accordance with
Section 4.10 hereof. Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Company in accordance with Section 4.10 hereof,
the Trustee will execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Note Guarantee. 
 (b) Upon designation of any Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture, such Guarantor will be released and relieved of any obligations under its Note Guarantee. 

(c) Upon Legal Defeasance or Covenant Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance
with Article 11 hereof, each Guarantor will be released and relieved of any obligations under its Note Guarantee. 
 Any Guarantor not
released from its obligations under its Note Guarantee as provided in this Section 10.05 will remain liable for the full amount of principal of and interest and premium, if any, on the Notes and for the other obligations of any Guarantor under
this Indenture as provided in this Article 10. 
 ARTICLE 11 
 SATISFACTION AND DISCHARGE 
 Section 11.01 Satisfaction and Discharge. 
 This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when: 
 (1) either: 
 (a) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Company, have been
delivered to the Trustee for cancellation; or 
  

 85 

 (b) all Notes that have not been delivered to the Trustee for cancellation have become
due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in
trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the
entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption; 
 (2) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the
Company or any Guarantor is bound; 
 (3) the Company or any Guarantor has paid or caused to be paid all sums payable by it
under this Indenture; and 
 (4) the Company has delivered irrevocable instructions to the Trustee under this Indenture to
apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be. 
 In addition, the Company must deliver
an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. 
 Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section 11.01, the provisions of Sections
11.02 and 8.06 hereof will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture or to
relieve the Company from its obligations with respect to the Notes under Article 2 and Section 4.02 hereof. 
 Section 11.02 Application
of Trust Money. 
 Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to
Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent)
as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the
extent required by law. 
 If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with
Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s
obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Company has made any payment of principal of, premium, if any, or
interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

interest thereon to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). Within 10 days following any

Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest or premium,
if any,) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an
acceleration or waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest or premium, if any, on, or the principal of, the Notes. The Company is

under the Notes, the Note Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are

 All things necessary to make this Indenture a valid and legally binding agreement of the Company, in accordance with its terms, have been done.

 NOW, THEREFORE, THIS INDENTURE WITNESSETH: 
 For and in consideration of the premises and the purchase of the Securities by the Holders (as herein defined) thereof, it is mutually covenanted and agreed, for the equal and proportionate benefit of all Holders of

(the “Required Currency”) into a currency in which a judgment will be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could
purchase in The City of New York the requisite amount of the Required Currency with the Judgment Currency on the New York Banking Day preceding the day on which a final unappealable judgment is given and (b) its obligations under this Indenture
to make payments in the Required Currency (i) shall not be discharged or satisfied by any tender, or any recovery pursuant to any judgment (whether or not entered in accordance with clause (a)), in any currency other than the Required Currency,
except to the extent that such tender or recovery shall result in the actual receipt, by the payee, of the full amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering 

  

 15 

 
in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full amount of the Required Currency so expressed to be
payable and (iii) shall not be affected by judgment being obtained for any other sum due under this Indenture. For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a legal holiday in The

 Section 303 Execution, Authentication, Delivery and Dating. 
 Securities shall be executed on behalf of the Company by any one of the Chairman of the Board of Directors, the Vice Chairman of the Board of Directors,
the Chief Executive Officer, the President, any Vice President, the Treasurer, any Assistant Treasurer, the Secretary or an Assistant Secretary and delivered to the Trustee. The signature of any of these officers on the Securities may be manual or
facsimile. 
 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, executed by the Company, to the
Trustee for authentication and, provided that the Board Resolution and Officers’ Certificate or supplemental indenture or indentures with respect to such Securities referred to in Section 301 and a Company Order for the authentication and
delivery of such Securities have been delivered to the Trustee, the Trustee in accordance with the Company Order and subject to the provisions hereof and of such Securities shall authenticate and deliver such Securities. In authenticating such
Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be provided with, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in
relying upon, 
 (1) an Opinion of Counsel to the effect that: 
 (a) the form or forms and terms of such Securities have been established in conformity with the provisions of this Indenture; 

(b) all conditions precedent to the authentication and delivery of such Securities have been complied with and that such Securities,
when completed by appropriate insertions, executed by duly authorized officers of the Company, delivered by duly authorized officers of the Company to the Trustee for authentication pursuant to this Indenture, and authenticated and delivered by the
Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms,
except as enforcement thereof may be subject to or limited by bankruptcy, insolvency, reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent transfer or other similar laws relating to or affecting creditors’ rights
generally, and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law) and will entitle the Holders thereof to the benefits of this Indenture; such Opinion of Counsel need express no
opinion as to the availability of equitable remedies; 
 (c) all laws and requirements in respect of the execution and
delivery by the Company of such Securities have been complied with; 
  

 22 

 and, to the extent that this Indenture is required to be qualified under the Trust Indenture Act in connection with the
issuance of such Securities, to the further effect that: 
 (d) this Indenture has been qualified under the Trust Indenture
Act; and 
 (2) an Officers’ Certificate stating that all conditions precedent to the execution, authentication and delivery of such
Securities have been complied with and that, to the best knowledge of the Persons executing such certificate, no event which is, or after notice or lapse of time would become, an Event of Default with respect to any of the Securities shall have
occurred and be continuing. 
 The Trustee shall not be required to authenticate or to cause an Authenticating Agent to authenticate any
Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee
or if the Trustee, being advised by counsel, determines that such action may not lawfully be taken. 
 Each Registered Security shall be
dated the date of its authentication. 
 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 in Section 202 or Section 612 executed by or on behalf of the Trustee or by the Authenticating Agent by the manual
signature of one of its authorized officers. Such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. 
 Section 304 Temporary Securities. 
 Pending the preparation
of definitive Securities, the Company may execute and deliver to the Trustee and, upon Company Order, the Trustee shall authenticate and deliver, in the manner provided in Section 303, temporary Securities in lieu thereof 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, in registered form and with such appropriate insertions,
omissions, substitutions and other variations as the officers of the Company executing such Securities may determine, as conclusively evidenced by their execution of such Securities. Such temporary Securities may be in global form. 
 Except in the case of temporary Securities in global form, which shall be exchanged in accordance with the provisions thereof, if temporary Securities
are issued, the Company shall cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities of the same series and containing terms and provisions that are identical to those of any temporary
Securities, such temporary Securities shall be exchangeable for such definitive Securities upon surrender of such temporary Securities at an Office or Agency for such Securities, without charge to any Holder thereof. Upon surrender for cancellation
of any one or more temporary Securities, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations of the same series and containing
identical terms and provisions. Unless 

  

 23 

 
otherwise provided in or pursuant to this Indenture with respect to a temporary global Security, 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 305 Registration, Transfer
and Exchange. 
 With respect to the Registered Securities of each series, if any, the Company shall cause to be kept a register (each such
register being herein sometimes referred to as the “Security Register”) at an Office or Agency for such series in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of the
Registered Securities of such series and of transfers of the Registered Securities of such series. 
 Such Office or Agency shall be the
“Security Registrar” or “Registrar” for that series of Securities. Unless otherwise specified in or pursuant to this Indenture or the Securities, the Trustee shall be the initial Security Registrar for each series of Securities.
The Company shall have the right to remove and replace from time to time the Security Registrar for any series of Securities; provided that no such removal or replacement shall be effective until a successor Security Registrar with respect to such
series of Securities shall have been appointed by the Company and shall have accepted such appointment by the Company. In the event that the Trustee shall not be or shall cease to be Security Registrar with respect to a series of Securities, it
shall have the right to examine the Security Register for such series at all reasonable times. There shall be only one Security Register for each series of Securities. 
 Upon surrender for registration of transfer of any Registered Security of any series at any Office or Agency for such series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Registered Securities of the same series denominated as authorized in or pursuant to this Indenture, of a like aggregate principal amount bearing a number not contemporaneously outstanding
and containing identical terms and provisions. 
 At the option of the Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series containing identical terms and provisions, in any authorized denominations, and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at any Office or Agency for such series.
Whenever any Registered Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive. 
 A global Security may not be transferred as a whole except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the
Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. Notwithstanding the foregoing, except as otherwise provided in or pursuant to this
Indenture, any global Security shall be exchangeable for definitive Securities only if (i) the Depository is at any time unwilling, unable or ineligible to continue as Depository and a successor depository is not appointed by the Company within
90 days of the date the Company is so informed in writing, (ii) the Depositary ceases to be a clearing agency registered under the Exchange Act of 1934, (iii) the Company executes and delivers to the 

  

 24 

 
Trustee a Company Order to the effect that such global Security shall be so exchangeable or (iv) an Event of Default has occurred and is continuing with
respect to the Securities. If the beneficial owners of interests in a global Security are entitled to exchange such interests for definitive Securities as the result of an event described in clause (i), (ii), (iii) or (iv) of the preceding
sentence, then without unnecessary delay but in any event not later than the earliest date on which such interests may be so exchanged, the Company shall deliver to the Trustee definitive Securities in such form and denominations as are required by
or pursuant to this Indenture, and of the same series, containing identical terms and in aggregate principal amount equal to the principal amount of such global Security, executed by the Company. On or after the earliest date on which such interests
may be so exchanged, such global Security shall be surrendered from time to time by the U.S. Depository or such other Depository as shall be specified in the Company Order with respect thereto, and in accordance with instructions given to the
Trustee and the U.S. Depository or such other Depository, as the case may be, as shall be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or in part, for
definitive Securities as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such surrendered global Security, a like aggregate principal amount of definitive Securities of
the same series of authorized denominations and of like tenor as the portion of such global Security to be exchanged; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any
selection of Securities of the same series to be redeemed and ending on the relevant Redemption Date. Promptly following any such exchange in part, such global Security shall be returned by the Trustee to such Depository or the U.S. Depository, as
the case may be, or such other Depository or U.S. Depository referred to above in accordance with the instructions of the Company referred to above. If a Registered portion of a global Security after the close of business at the Office or Agency for
such Security where such exchange occurs on or after (i) any Regular Record Date for such Security and before the opening of business at such Office or Agency on the next Interest Payment Date, or (ii) any Special Record Date for such
Security and before the opening of business at such Office or Agency on the related proposed date for payment of interest or Defaulted Interest, as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for
payment, as the case may be, in respect of such Registered Security, but shall be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such global
Security shall be payable in accordance with the provisions of this Indenture. 
 All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid and legally binding obligations of the Company evidencing the same debt and entitling the Holders thereof to the same benefits under this Indenture as the Securities surrendered upon such registration of
transfer or exchange. 
 Every Registered Security presented or surrendered for registration of transfer or for exchange or redemption shall
(if so required by the Company or the Security Registrar for such Security) be duly endorsed, signature guaranteed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar for such
Security duly executed by the Holder thereof, signature guaranteed, or his attorney duly authorized in writing. 
  

 25 

 No service charge shall be made for any registration of transfer or exchange, or redemption of
Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge and any other expenses (including fees and expenses of the Trustee) that may be imposed in connection with any registration of transfer
or exchange of Securities, other than exchanges pursuant to Sections 304, 306 and 1107 not involving any transfer. 
 Except as otherwise
provided in or pursuant to this Indenture, the Company shall not be required (i) to issue, register the transfer of or exchange any Securities during a period beginning at the opening of business 15 days before the day of selection of
Securities of like tenor and the same series under Section 1103 for redemption and ending at the close of business on the day of such selection, (ii) to register the transfer of or exchange any Registered Security so selected for
redemption in whole or in part, except in the case of any Security to be redeemed in part, the portion thereof not to be redeemed; or (iii) to issue, register the transfer of or exchange any Security which, in accordance with its terms, has
been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security not to be so repaid. 
 Section 306 Mutilated,
Destroyed, Lost and Stolen Securities. 
 If any mutilated Security is surrendered to the Trustee, subject to the provisions of this
Section 306, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously
outstanding. 
 If there be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or
theft of any Security, and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or to a Responsible Officer of the Trustee that
such Security has been acquired by a protected purchaser, the Company shall execute and, upon the Company’s request the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Security, a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding. 
 Notwithstanding the foregoing provisions of this Section 306, in case any mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead
of issuing a new Security, pay such Security. 
 Upon the issuance of any new Security under this Section, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
 Every new Security issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute a separate obligation of the
Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of such series duly
issued hereunder. 
  

 26 

 The provisions of this Section, as amended or supplemented pursuant to this Indenture with respect to
particular Securities or generally, shall be 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 307 Payment of Interest and Certain Additional Amounts; Rights to Interest and Certain Additional Amounts Preserved. 
 Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to any Registered Security which shall
be payable, and are 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 as of the close of business on the Regular Record
Date for such interest. 
 Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with
respect to any Registered Security which shall be payable, but shall not be punctually paid or duly provided for, on any Interest Payment Date for such Registered Security (herein called “Defaulted Interest”) shall forthwith cease to be
payable to the Holder thereof on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

 (1) The Company may elect to make payment of any Defaulted Interest to the Person in whose name such Registered Security (or a Predecessor
Security thereof) shall be 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 such Registered Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect
of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when so deposited to be held in trust for the benefit of the Person entitled to such
Defaulted Interest as in this clause provided. Thereupon, the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment
and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to the Holder of such Registered Security (or a Predecessor Security thereof) at his address as it appears in the Security
Register not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in an Authorized Newspaper of general
circulation in the Borough of Manhattan, The City of New York, but such publication shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted 

  

 27 

 
Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Person in whose name such
Registered Security (or a Predecessor Security thereof) shall be registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). 
 (2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange
on which such Security 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 payment shall be deemed practicable by the
Trustee. 
 Unless otherwise provided in or pursuant to this Indenture or the Securities of any particular series pursuant to the provisions
of this Indenture, at the option of the Company, interest on Registered Securities that bear interest may be paid by wire transfer in immediately available funds if the holder of the Registered Security has provided to the Company and the Trustee
wire instructions at least five business days prior to the applicable payment date or by check mailed to the address of that holder as it appears on the books of the Securities Registrar if that holder has not provided wire instructions; provided
that the final distribution in respect of any Security will be made only upon presentation and surrender of such certificated debenture at the applicable Corporate Trust Office of the Trustee. 
 Subject to the foregoing provisions of this Section and Section 305, 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. 
 In the case of any Registered Security of any series that is convertible, which Registered Security is converted after any Regular Record Date and on or prior to the next succeeding Interest Payment Date (other than
any Registered Security with respect to which the Stated Maturity is prior to such Interest Payment Date), interest with respect to which the Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date
notwithstanding such conversion, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Registered Security (or one or more predecessor Registered Securities) is registered at the close
of business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Registered Security which is converted, interest with respect to which the Stated Maturity is after the date of
conversion of such Registered Security shall not be payable. 
 Section 308 Persons Deemed Owners. 
 Prior to due presentment of a Registered 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 such Registered Security is registered in the Security Register as the owner of such Registered Security for the purpose of receiving payment of principal of, any premium and (subject to Section 305 and
Section 307) interest on and any Additional Amounts with respect to such Registered Security and for all other purposes whatsoever, whether or not any payment with respect to such Registered Security shall be overdue, and none of the Company,
the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary. 
  

 28 

 No Holder of any beneficial interest in any global Security held on its behalf by a Depository shall have
any rights under this Indenture with respect to such global Security, and such Depository may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the owner of such global Security for all purposes whatsoever. None
of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a global Security or for
maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 
 Section 309 Cancellation. 
 All Securities surrendered for payment, redemption, registration of transfer, exchange or conversion or for credit against any sinking fund payment shall,
if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities, as well as Securities surrendered directly to the Trustee for any such purpose, shall be cancelled promptly by the Trustee. 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 cancelled promptly 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 or pursuant to this Indenture. All cancelled Securities held by the Trustee shall be
disposed of by the Trustee in accordance with its customary procedures. 
 Section 310 Computation of Interest. 
 Except as otherwise provided in or pursuant to this Indenture, or in any Security, interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months. 
 Section 311 CUSIP Numbers. 
 The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders;
provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other
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.

 ARTICLE FOUR 
 SATISFACTION AND DISCHARGE OF INDENTURE 
 Section 401 Satisfaction and Discharge. 
 Upon the direction of the Company by a Company Order, this Indenture shall cease to be of further effect with respect to any series of Securities
specified in such Company Order and the Trustee, on receipt of a Company Order, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture as to such series, when 
 (1) either 
 (a) all
Securities of such series theretofore authenticated and delivered and have been accepted by the Trustee for cancellation (other than (i) Securities of such series which have been destroyed, lost or stolen and which have been replaced or paid as
provided in Section 306, and (ii) Securities of such series for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust,
as provided in Section 1003); or 
 (b) all Securities of such series not theretofore delivered to the Trustee for
cancellation: 
  

	 	(i)	have become due and payable, or 

  

	 	(ii)	will become due and payable at their Stated Maturity within one year, or 

  

	 	(iii)	if redeemable at the option of the Company, are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by
the Trustee in the name, and at the expense, of the Company, 

 and the Company, in the case of (i), (ii) or (iii) above, has
deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose, money in the Currency in which such Securities are payable in an amount sufficient to pay and discharge the entire indebtedness on such Securities not
theretofore delivered to the Trustee for cancellation, including the principal of, any premium and interest on, and any Additional Amounts with respect to such Securities, to the date of such deposit (in the case of Securities which have become due
and payable) or to the Maturity thereof, as the case may be; 
 (2) the Company has paid or caused to be paid all other sums payable
hereunder by the Company with respect to the Outstanding Securities of such series; and 
 (3) the Company has delivered to the Trustee an
Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture as to such series have been complied with. 
  

 30 

 In the event there are Securities of two or more series hereunder, the Trustee shall be required to
execute an instrument acknowledging satisfaction and discharge of this Indenture only if requested to do so with respect to Securities of such series as to which it is Trustee and if the other conditions thereto are met. 
 Notwithstanding the satisfaction and discharge of this Indenture with respect to any series of Securities, the obligations of the Company to the Trustee
under Section 607 and, if money shall have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the obligations of the Company and the Trustee with respect to the Securities of such series under
Section 305, Section 306, Section 403, Section 1002 and Section 1003, with respect to the payment of Additional Amounts, if any, with respect to such Securities as contemplated by Section 1004 (but only to the extent
that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 401(1)(b), and with respect to any rights to convert or exchange such Securities into
Common Stock or other securities, cash or other property) shall survive such satisfaction and discharge. 
 Section 402 Defeasance and Covenant Defeasance.

 (1) Unless pursuant to Section 301, either or both of (i) defeasance of the Securities of or within a series under clause
(2) of this Section 402 shall not be applicable with respect to the Securities of such series or (ii) covenant defeasance of the Securities of or within a series under clause (3) of this Section 402 shall not be applicable
with respect to the Securities of such series, then such provisions, together with the other provisions of this Section 402 (with such modifications thereto as may be specified pursuant to Section 301 with respect to any Securities), shall
be applicable to such Securities, and the Company may at its option by Board Resolution, at any time, with respect to such Securities, elect to have Section 402(2) or Section 402(3) be applied to such Outstanding Securities upon compliance
with the conditions set forth below in this Section 402. 
 (2) Upon the Company’s exercise of the above option applicable to this
Section 402(2) with respect to any Securities of or within a series, the Company shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities on the date the conditions set forth in clause (4) of
this Section 402 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by such Outstanding Securities, which
shall thereafter be deemed to be “Outstanding” only for the purposes of clause (6) of this Section 402 and the other Sections of this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all of 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 such Outstanding Securities to receive, solely from the trust fund described in clause (4) of this Section 402 and as more fully set forth in
such Section, payments in respect of the principal of (and premium, if any) and interest, if any, on, and Additional Amounts, if any, with respect to, such Securities when such payments are due, and any rights of such Holder to convert or exchange
such Securities into Common Stock or other securities, cash or other property, (ii) the obligations of 

  

 31 

 
the Company and the Trustee with respect to such Securities under Section 305, Section 306, Section 1002 and Section 1003 and with
respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 1004 (but only to the extent that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such
Additional Amounts pursuant to Section 402(4)(a) below), and with respect to any rights to convert or exchange such Securities into Common Stock or other securities, cash or other property, (iii) the rights, powers, trusts, duties and
immunities of the Trustee under this Indenture and (iv) this Section 402. The Company may exercise its option under this Section 402(2) notwithstanding the prior exercise of its option under clause (3) of this Section 402
with respect to such Securities. 
 (3) Upon the Company’s exercise of the above option applicable to this Section 402(3) with
respect to any Securities of or within a series, the Company shall be released from, to the extent specified pursuant to Section 301, any covenant applicable to such Securities, with respect to such Outstanding Securities on and after the date
the conditions set forth in clause (4) of this Section 402 are satisfied (hereinafter, “covenant defeasance”), and such Securities shall thereafter be deemed to be not “Outstanding” for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with any such covenant, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to such Outstanding Securities, 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 covenant or by reason of 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 501(4) insofar as it relates to, to the extent specified pursuant to Section 301, any covenant applicable to such Security, or Section 501(7) or otherwise, as the case may be, but, except as specified above, the remainder of
this Indenture and such Securities shall be unaffected thereby. 
 (4) The following shall be the conditions to application of clause
(2) or (3) of this Section 402 to any Outstanding Securities of or within a series: 
 (a) The Company shall
irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 608 who shall agree to comply with the provisions of this Section 402 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, (1) an amount in Dollars or in such Foreign Currency in which such Securities
are then specified as payable at Stated Maturity, or (2) Government Obligations applicable to such Securities (determined on the basis of the Currency in which such Securities are then specified as payable at Stated Maturity) 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 of principal of (and premium, if any) and interest, if any, on such Securities,
money in an amount, or (3) a combination thereof, in any case (be it under clause (1), (2) or (3)), in an amount, sufficient, without consideration of any reinvestment of such principal and interest, in the opinion of a nationally
recognized Independent Registered Public Accounting Firm expressed in a written certification 

  

 32 

 
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,
(y) the principal of (and premium, if any) and interest, if any, on such Outstanding Securities an the Stated Maturity of such principal or installment of principal or interest and (z) any mandatory sinking fund payments or analogous
payments applicable to such Outstanding Securities on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities. 
 (b) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or
any other material agreement or instrument to which the Company is a party or by which it is bound. 
 (c) No Event of Default
or event which with notice or lapse of time or both would become an Event of Default with respect to such Securities shall have occurred and be continuing on the date of such deposit and, with respect to defeasance only, at any time during the
period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period). 
 (d) In the case of an election under clause (2) of this Section 402, the Company shall have delivered to the Trustee an Opinion
of Counsel stating that 
  

	 	(i)	the Company has received from the Internal Revenue Service a letter ruling, or there has been published by the Internal Revenue Service a Revenue Ruling, or

  

	 	(ii)	since the date of execution of this Indenture, there has been a change in the applicable Federal income tax law, 

 in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of such Outstanding Securities will not recognize income, gain or loss
for Federal income tax purposes as a result of such 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 defeasance had not occurred. 
 (a) In the case of an election under clause (3) of this Section 402, the Company shall have delivered to the Trustee an Opinion
of Counsel to the effect that the Holders of such Outstanding Securities 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. 
 (b) The
Company shall have delivered to the Trustee an Opinion of Counsel to the effect that, after the 91st day after the date of establishment of such trust, all money and Government Obligations (or other property as may be provided pursuant to
Section 301) (including the proceeds thereof) deposited or caused to be deposited with the Trustee (or other qualifying trustee) pursuant to this clause (4) to be held in trust will not 

  

 33 

 
be subject to any case or proceeding (whether voluntary or involuntary) in respect of the Company under any Federal or State bankruptcy, insolvency,
reorganization or other similar law, or any decree or order for relief in respect of the Company issued in connection therewith. 
 (c) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance or covenant defeasance under clause (2) or (3) of this
Section 402 (as the case may be) have been complied with. 
 (d) Notwithstanding any other provisions of this
Section 402(4), such defeasance or covenant defeasance shall be effected in compliance with any additional or substitute terms, conditions or limitations which may be imposed on the Company in connection therewith pursuant to Section 301.

 (5) Subject to the provisions of the last paragraph of Section 1003, all money and Government Obligations (or other property as may
be provided pursuant to Section 301) (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 402(5) and Section 403, the “Trustee”) pursuant to
clause (4) of Section 402 in respect of any 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), 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 and Additional Amounts, if any,
but such money need not be segregated from other funds except to the extent required by law. 
 (6) Unless otherwise specified in or pursuant
to this Indenture or any Security, if, after a deposit referred to in Section 402(4)(a) has been made, (a) the Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 301 or
the terms of such Security to receive payment in a Currency other than that in which the deposit pursuant to Section 402(4)(a) has been made in respect of such Security, or (b) a Conversion Event occurs in respect of the Foreign Currency

other property deposited in respect of such Security into the Currency in which such Security becomes payable as a result of such election or Conversion Event based on (x) in the case of payments made pursuant to clause (a) above, the
applicable market exchange rate for such Currency in effect on the second Business Day prior to each payment date, or (y) with respect to a Conversion Event, the applicable market exchange rate for such Foreign Currency in effect (as nearly as
feasible) at the time of the Conversion Event. 
 The Company shall pay and indemnify the Trustee against any tax, fee or other charge,
imposed on or assessed against the Government Obligations deposited pursuant to this Section 402 or the principal or 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
such Outstanding Securities. 
  

 34 

 Anything in this Section 402 to the contrary notwithstanding, the Trustee shall deliver or pay to
the Company from time to time upon Company Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in clause (4) of this Section 402 which, in the opinion of a nationally recognized
Independent Registered Public Accounting Firm 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 a defeasance or covenant defeasance, as
applicable, in accordance with this Section 402.

(6) of Section 501) occurs and is continuing, then the Trustee may, and at the direction of the Holders of not less than 25% in principal amount of the Outstanding Securities of such series shall declare the principal of all the Securities
of such series, or such lesser amount as may be provided for in the Securities of such series, to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any declaration the
principal or such lesser amount shall become immediately due and payable. If an Event of Default specified in clause (5) or (6) of Section 501 above occurs, all unpaid principal of and accrued interest on the Outstanding Securities of
that series (or such lesser amount as may be provided for in the Securities of such series) shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of any Security of such series.

 At any time after a declaration of acceleration or automatic acceleration with respect to the 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 hereafter in this Article provided, the Holders of not less than a majority in principal amount of the Outstanding Securities of such series, by written
notice to the Company and the Trustee, may rescind and annul the declaration and its consequences if: 
 (1) the Company has paid or deposited
with the Trustee a sum of money sufficient to pay (i) all overdue installments of interest on all Securities of such series and any Additional Amounts payable with respect thereto, (ii) the principal of and any premium on any Securities of
the series which have become due otherwise than by the declaration of acceleration and interest thereon and any Additional Amounts with respect thereto at the rate or rates borne by or provided in such Securities, (iii) interest upon overdue
interest at the rate or rates prescribed therefor in such Securities, and (iv) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and

 (2) all Events of Default with respect to Securities of such series, other than the non-payment of the principal of, any premium and
interest on, and any additional amounts with respect to Securities of such series which shall have become due solely by the acceleration, shall have been cured or waived as provided in Section 513. 
 Section 503 Collection of Indebtedness and Suits for Enforcement by Trustee. 
 The Company covenants that if 
 (1) default is made in the payment of any installment of interest on any
Security, or any Additional Amounts payable with respect thereto, when such interest or Additional Amounts shall have become due and payable and such default continues for a period of 60 days, or 
  

 37 

 (2) default is made in the payment of any principal of or premium, if any, on, or any Additional Amounts
payable in respect of any principal of or premium, if any, on any Security at its Maturity; 
 the Company shall, upon demand of the Trustee,
pay to the Trustee, for the benefit of the Holders of such Securities, the whole amount of money then due and payable with respect to such Securities, with interest upon the overdue principal, any premium and, to the extent that payment of such
interest shall be legally enforceable, upon any overdue installments of interest and Additional Amounts at the rate or rates borne by or provided for in such Securities, and, in addition thereto, such further amount of money 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 and all other amounts due to the Trustee under Section 607. 
 If the Company fails to pay the money it is required to pay the Trustee pursuant to the preceding paragraph forthwith upon the demand of the Trustee, the
Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the money so due and unpaid, and 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 monies 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 and at the direction of the Holders of not less
than 25% in principal amount of the Outstanding Securities of such series shall, so long as such Holders shall have provided the Trustee with such indemnity as it shall require, proceed to protect and enforce its rights and the rights of the Holders
of Securities of such series by such appropriate judicial proceedings to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or such Securities or in aid of the exercise of any
power granted herein or therein, or to enforce any other proper remedy. 
 Section 504 Trustee May File Proofs of Claim. 
 In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable
as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of any overdue principal, premium, interest or Additional Amounts) shall be entitled and empowered,
by intervention in such proceeding or otherwise, 
 (1) to file and prove a claim for the whole amount, or such lesser amount as may be
provided for in the Securities of such series, of the principal and any premium, interest and Additional Amounts owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to
have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents or counsel) and of the Holders of Securities allowed in such judicial proceeding, and 
  

 38 

 (2) to collect and receive any monies or other property payable or deliverable on any such claims and to
distribute the same; 
 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is
hereby authorized by each Holder of Securities 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 of Securities, to pay to 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 607. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security 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 of a Security in any such proceeding. 
 Section 505 Trustee May Enforce Claims without Possession of Securities. 
 All rights of action and
claims under this Indenture or any of the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by
the Trustee shall be brought in its own name as trustee of an express trust, and any recovery or judgment, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel,
shall be for the ratable benefit of each and every Holder of a Security in respect of which such judgment has been recovered. 
 Section 506 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 case of the distribution of such money on account of principal, or any premium, interest or Additional Amounts, 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 and any predecessor Trustee under
Section 607; 
 SECOND: To the payment of the amounts then due and unpaid upon the Securities for principal and any premium, interest
and Additional Amounts in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the aggregate amounts due and payable on such Securities for principal and any
premium, interest and Additional Amounts, respectively; 
 THIRD: The balance, if any, to the Company.

 Section 507 Limitations on Suits. 
 No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless 
 (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the
Securities of such series; 
 (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of such series shall
have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
 (3) such Holder or Holders have offered to the Trustee indemnity satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request; 
 (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and 

(5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities of such series; 
 it being understood and intended that no one or more of such Holders shall have any right
in any manner whatever by virtue of, or by availing of, any provision of this Indenture or any Security to affect, disturb or prejudice the rights of any other such Holders or Holders of Securities of any other series, or to obtain or to seek to
obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders. 
 Section 508 Unconditional Right of Holders to Receive Principal and any Premium, Interest and Additional Amounts. 
 Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of, any premium and (subject to Section 305 and Section 307) interest on, and any Additional Amounts with respect to such Security, on the respective Stated Maturity or Maturities therefor specified in such
Security (or, in the case of redemption, on the Redemption Date or, in the case of repayment at the option of such Holder if provided in or pursuant to this Indenture, on the date such repayment is due) and to institute suit for the enforcement of
any such payment, and such right shall not be impaired without the consent of such Holder. 
 Section 509 Restoration of Rights and Remedies.

 If the Trustee or any Holder of a Security 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 the Company, the Trustee and each such Holder shall, subject to any 

  

 40 

 
determination in such proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the
Trustee and each such Holder shall continue as though no such proceeding had been instituted. 
 Section 510 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 306, no right or remedy herein conferred upon or reserved to the Trustee or to each and every Holder of a Security is intended to be exclusive of any other right or remedy, and every right and remedy, to the extent permitted by law,
shall 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, to the extent
permitted by law, prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 Section 511 Delay or Omission Not Waiver.

 No delay or omission of the Trustee or of any Holder of any Security 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 any Holder of a Security may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or by such Holder, as the case may be. 
 Section 512 Control by Holders of Securities.

 Subject to Section 602(5), the Holders of a majority in principal amount of the Outstanding Securities of any series shall have the
right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Securities of such series, provided that 
 (1) such direction shall not be in conflict with any rule of law or with this Indenture or with the Securities of any series, 
 (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and 
 (3) such direction is not unduly prejudicial to the rights of the other Holders of Securities of such series not joining in such action, or subject the
Trustee to personal liability. 
 Section 513 Waiver of Past Defaults. 
 The Holders of not less than a majority in principal amount of the Outstanding Securities of any series on behalf of the Holders of all the Securities of such series may waive any past default hereunder with respect
to such series and its consequences, except a default 
 (1) in the payment of the principal of, any premium or interest on, or any Additional
Amounts with respect to, any Security of such series, or 
  

 41 

 (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended
without the consent of the Holder of each Outstanding Security of such series affected. 
 Upon any such waiver, such default shall cease to
exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 
 Section 514 Waiver of Stay or Extension Laws. 
 The
Company covenants that (to the extent that it may lawfully do so) it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time
hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company expressly waives (to the extent that it may lawfully do so) all benefit or advantage of any such law and covenants that it will not hinder,
delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
 Section 515 Undertaking for Costs. 
 All parties to this Indenture agree, and each Holder of any
Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of any undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses,
against any party litigant in such suit having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 515 shall not apply to any suit instituted by the Trustee, to any
suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of Outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement of the payment of the principal of
(or premium, if any) or interest, if any, on or Additional Amounts, if any, with respect to any Security on or after the respective Stated Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date, and, in
the case of repayment, on or after the date for repayment) or for the enforcement of the right, if any, to convert or exchange any Security into Common Stock or other securities, cash or other property in accordance with its terms.

pursuant to Section 703, notice of such default hereunder actually known to a Responsible Officer of the Trustee, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in the payment of
the principal of (or premium, if any), or interest, if any, on, or Additional Amounts or any sinking fund or purchase fund installment with respect to, any Security of such series, the Trustee shall be protected in withholding such notice if and so

such series; and provided, further, that in the case of any default of the character specified in Section 501(4) with respect to Securities of such series, no such notice to Holders shall be given until at least 30 days after the occurrence

 46 

 Section 606 Money Held in Trust. 
 Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder
except as otherwise agreed in writing with the Company. 
 Section 607 Compensation and Reimbursement. 
 The Company agrees: 
 (1) to pay to the
Trustee from time to time such compensation as shall be agreed upon from time to time in writing between the Company and the Trustee for all services rendered by the Trustee hereunder (which compensation shall not be limited by any provision of law
in regard to the compensation of a trustee of an express trust); 
 (2) except as otherwise expressly provided herein, to reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture arising out of or in connection with the acceptance or administration of the trust or
trusts hereunder (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be caused by the Trustee’s own negligence or willful misconduct; and

 (3) to fully indemnify each of the Trustee and any predecessor Trustee and its agents, officers, directors and employees for, and to hold
them harmless against, any loss, liability, damage, claim or expense (including reasonable legal fees and expenses), including taxes (other than taxes based on the income of the Trustee), incurred without negligence or willful misconduct on their
part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the reasonable costs and expenses of defending themselves against any claim or liability (whether asserted by the Company, a
Holder of Securities, or any other Person) in connection with the exercise or performance of any of their powers or duties hereunder. 
 As
security for the performance of the payment obligations of the Company under this Section, the Trustee shall have a lien prior to the Securities of any series upon all property and funds held or collected by the Trustee as such, except funds held in
trust for the payment of principal of, and premium or interest on or any Additional Amounts with respect to any Securities. Such lien shall survive the resignation or removal of the Trustee and the satisfaction and discharge of this Indenture. When
the Trustee incurs expenses or renders services after a Default or Event of Default specified in Section 501(5) and 501(6) hereof occurs, the expenses and the compensation for the services (including the fees and expense of its agents and
counsel) are intended to constitute expense of administration under U.S. Code, Title 11 or any other similar foreign, federal or state law for the relief of debtors. 
 To the extent permitted by law any compensation or expense incurred by the Trustee after a default specified in or pursuant to Section 501 is intended to constitute an expense of administration under any then
applicable bankruptcy or insolvency law. “Trustee” for purposes of this Section 607 shall include any predecessor Trustee but the negligence or willful misconduct of any Trustee shall not affect the rights of any other Trustee under
this Section 607. 
  

 47 

 Notwithstanding any other provision of this Indenture to the contrary, in no event shall the Trustee be
liable for special, indirect or consequential damages of any kind whatsoever (including but not limited to lost profits) even if the Trustee had been advised of the likelihood of such loss or damage and regardless of the form of action. 

The provisions of this Section 607 shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the
Trustee and shall apply with equal force and effect to the Trustee in its capacity as Authenticating Agent, Paying Agent or Security Registrar. 
 Section 608 Corporate Trustee Required; Eligibility. 
 There shall at all times be a Trustee hereunder that is a Corporation,
organized and doing business under the laws of the United States of America, any state thereof or the District of Columbia, eligible under Section 310(a)(1) of the Trust Indenture Act to act as trustee under an indenture qualified under the
Trust Indenture Act and that has a combined capital and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000 subject to supervision or examination by Federal or state authority. 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. 
 Section 609 Resignation and Removal; Appointment of Successor. 
 (1) 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 pursuant to Section 610. 
 (2) The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 610 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 such series. 
 (3) The Trustee may
be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and the Company. If the instrument of acceptance by a
successor Trustee required by Section 610 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 such series. The Trustee for one or more series of Securities may be removed by the Company, so long as no Event of Default has occurred and is continuing with respect to such
series. 
 (4) If at any time: 
 (a) the Trustee shall fail to comply with the obligations imposed upon it under Section 310(b) of the Trust Indenture Act with respect to Securities of any series after written request therefor by the Company or
any Holder of a Security of such series who has been a bona fide Holder of a Security of such series for at least six months, or 
  

 48

resign after written request therefor by the Company or any such Holder, or 
 (c) 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, 
  

	 	(i)	the Company, by or pursuant to a Company Order, may remove the Trustee with respect to all Securities or the Securities of such series, or 

  

	 	(ii)	subject to Section 515, any Holder of a Security who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others

respect to the Securities of one or more series, the Company, by or pursuant to a Company Order, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of such series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable
requirements of Section 610. If, within one year after such resignation, removal or incapacity, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a

Securities, if any, of such series as their names and addresses appear in the Security Register. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

 (1) Upon the appointment hereunder of any successor Trustee with respect to all Securities, such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and 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
hereunder of the retiring Trustee; but, on the request of the Company or such successor Trustee, such retiring Trustee, upon payment of its charges, shall execute and deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and, subject to Section 1003, shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, subject nevertheless to its claim, if any,

appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts
and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions
of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust, that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee and that no Trustee shall be responsible for any
notice given to, or received by, or any act or failure to act on the part of any other Trustee hereunder, and, upon the execution and delivery of such supplemental indenture, the resignation or removal of the retiring Trustee shall become effective
to the extent provided therein, such retiring Trustee shall have no further responsibility for the exercise of rights and powers or for the performance of the duties and obligations vested in the Trustee under this Indenture with respect to the
Securities of that or those series to which the appointment of such successor Trustee relates other than as hereinafter expressly set forth, 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 with respect to the Securities of that or those 

  

 50 

 
series to which the appointment of such successor Trustee relates; but, on request of the Company or such successor Trustee, such retiring Trustee, upon
payment of its charges with respect to the Securities of that or those series to which the appointment of such successor Trustee relates and subject to Section 1003 shall duly assign, transfer and deliver to such successor Trustee, to the
extent contemplated by such supplemental indenture, the property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, subject to its

VI without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case 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. 
 Section 612 Appointment of Authenticating Agent. 
 The
Trustee may appoint one or more Authenticating Agents acceptable to the Company with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of that or those series issued upon
original issue, exchange, registration of transfer, partial redemption or partial repayment or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent.

 51 

 
Indenture Act) of at least $50,000,000. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section,
it shall resign immediately in the manner and with the effect specified in this Section. 
 Any Corporation into which an Authenticating
Agent may be merged or converted or with which it may be consolidated, or any Corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any Corporation succeeding to all or
substantially all of the corporate agency or corporate trust business of an Authenticating Agent, shall be the successor of such Authenticating Agent hereunder, provided such Corporation shall be otherwise eligible under this Section, without the
execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. 
 An Authenticating Agent may
resign at any time by giving written notice thereof to the Trustee and the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and the Company. Upon
receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of Registered Securities, if any, of the series with respect to which such Authenticating Agent
shall serve, as their names and addresses appear in the Security Register. Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder,
with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 
 The Company agrees to pay each Authenticating Agent from time to time reasonable compensation for its services under this Section. 
 The provisions of Section 303, Section 601, Section 604 and Section 605 shall be applicable to each Authenticating Agent. 

If an Authenticating Agent is appointed with respect to one or more series of Securities pursuant to this Section, the Securities of such series may
have endorsed thereon, in addition to or in lieu of the Trustee’s certificate of authentication, an alternate certificate of authentication in substantially the following form: 
 This is one of the Certificates described in the within-mentioned Indenture.

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 provided in or pursuant to this Indenture; 
 (2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities of such series) in the making of any payment of
principal, any premium or interest on or any Additional Amounts with respect to the Securities of such series; and 
 (3) 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 terms 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. 
 Except as otherwise provided herein or pursuant
hereto, 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, any premium or interest on or any Additional Amounts with respect to any Security of any series and
remaining unclaimed for two years after such principal or any such premium or interest or any such Additional Amounts shall have become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and
all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in an
Authorized Newspaper in each Place of Payment for such series or to be mailed to Holders of Registered Securities of such series, or both, 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 or mailing nor shall it be later than two years after such principal and any premium or interest or Additional Amounts shall have become due and payable, any unclaimed balance of such money then
remaining will be repaid to the Company.

 Section 1004 Additional Amounts. 
 If any Securities of a series provide for the payment of Additional Amounts, the Company agrees to pay to the Holder of any such Security Additional Amounts as provided in or pursuant to this Indenture or such
Securities. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series, such mention shall be deemed to include mention of the payment of
Additional Amounts provided by the terms of such series established hereby or pursuant hereto to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to such terms, and express mention of the
payment of Additional Amounts (if applicable) in any provision hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made. 
 Except as otherwise provided in or pursuant to this Indenture or the Securities of the applicable series, if the Securities of a series provide for the
payment of Additional Amounts, at least 10 days prior to the first Interest Payment Date with respect to such series of Securities (or if the Securities of such series shall not bear interest prior to Maturity, the first day on which a payment of
principal is made), and at least 10 days prior to each date of payment of principal or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers’ Certificate, the Company shall furnish to the
Trustee and the principal Paying Agent or Paying Agents, if other than the Trustee, an Officers’ Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and premium, if any, or interest on
the Securities of such series shall be made to Holders of Securities of such series who are United States Aliens (as demonstrated by delivery of appropriate tax forms) without withholding for or on account of any tax, assessment or other
governmental charge described in the Securities of such series. If any such withholding shall be required, then such Officers’ Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of
Securities, and the Company agrees to pay to the Trustee or such Paying Agent the Additional Amounts required by the terms of such Securities. The Company covenants to indemnify the Trustee and any Paying Agent for, and to hold them harmless
against, any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers’ Certificate furnished pursuant
to this Section. 
 Section 1005 Corporate Existence. 
 Subject to Article Eight, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and its rights (charter and statutory) and franchises;
provided, however, that the foregoing shall not obligate the Company to preserve any such right or franchise if the Company shall determine that the preservation thereof is no longer desirable in the conduct of its business. 
 Section 1006 Waiver of Certain Covenants. 
 The Company
may omit in any particular instance to comply with any term, provision or condition set forth in Sections 1003 and 1005 with respect to the Securities of any series if before the time for such compliance the Holders of at least a 66-2/3% majority in
principal amount of 

  

 62 

 
the Outstanding Securities of such series, by Act of such Holders, either shall waive such compliance in such instance or generally shall have waived
compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company
and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. 
 Section 1007 Company
Statement as to Compliance; Notice of Certain Defaults. 
 (1) If any Securities are Outstanding under this Indenture, the Company shall
deliver to the Trustee, within 120 days after the end of each fiscal year, a written statement (which need not be contained in or accompanied by an Officers’ Certificate) signed by the principal executive officer, the principal financial
officer, the principal accounting officer or other officer authorized by the Board of Directors of the Company, stating that 
 (a) a review of the activities of the Company during such year and of its performance under this Indenture has been made under his or her supervision, and 
 (b) to the best of his or her knowledge, based on such review, (a) the Company has complied with all the conditions and covenants
imposed on it under this Indenture throughout such year, or, if there has been a default in the fulfillment of any such condition or covenant, specifying each such default known to him or her and the nature and status thereof, and (b) no event
has occurred and is continuing which is, or after notice or lapse of time or both would become, an Event of Default, or, if such an event has occurred and is continuing, specifying each such event known to him or her and the nature and status
thereof. 
 (2) The Company shall deliver to the Trustee, within 10 days after the occurrence thereof, written notice of any Event of Default
or any event which after notice or lapse of time or both would become an Event of Default pursuant to clause (5) of Section 501. 
 Section 1008 Calculation of Original Issue Discount. 
 The Company shall file with the Trustee promptly at the end of each
calendar year (i) a 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. 
 ARTICLE
ELEVEN 
 REDEMPTION OF SECURITIES 
 Section 1101 Applicability of Article. 
 Redemption of Securities of any series at the option of the Company as permitted or
required by the terms of such Securities shall be made in accordance with the terms of such Securities and (except as otherwise provided herein or pursuant hereto) this Article. 
  

 63 

 Section 1102 Election to Redeem; Notice to Trustee. 
 The election of the Company to optionally redeem any Securities shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the
election of the Company of (a) less than all of the Securities of any series or (b) all of the Securities of any series with the same issue date, interest rate or formula, Stated Maturity and other terms, 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), notify the Trustee of such Redemption Date and of the principal amount of Securities of such series to be redeemed. 
 Section 1103 Selection by Trustee of Securities to be Redeemed. 
 If less than all of the Securities of any series with the same issue date, interest rate or formula, Stated Maturity and other terms are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior
to the Redemption Date by the Trustee from the Outstanding Securities of such series not previously called for redemption, pro rata, by lot, or by such other method as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions of the principal amount of Registered Securities of such series; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Registered Security of such series not
redeemed to less than the minimum denomination for a Security of such series established herein or pursuant hereto. 
 The Trustee shall
promptly notify the Company and the Security Registrar (if other than itself) 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 the redemption of Securities shall
relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal of such Securities which has been or is to be redeemed. 
 Unless otherwise specified in or pursuant to this Indenture or the Securities of any series, if any Security selected for partial redemption is converted into or exchanged for Common Stock or other securities, cash or
other property in part before termination of the conversion or exchange right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for
redemption. Securities which have been converted or exchanged during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection. 
 Section 1104 Notice of Redemption. 
 Notice of
redemption shall be given in the manner provided in Section 106, not less than 30 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to the Holders of Securities to be
redeemed. Failure to give notice by mailing in the manner herein provided to the Holder of any Registered Securities designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of
the proceedings for the redemption of any other Securities or portion thereof. 
  

 64 

 Any notice that is mailed to the Holder of any Registered Securities in the manner herein provided shall
be conclusively presumed to have been duly given, whether or not such Holder receives the notice. 
 All notices of redemption shall state:

 (1) the Redemption Date, 
 (2)
the Redemption Price, 
 (3) if less than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case
of partial redemption, the principal amount) of the particular Security or Securities to be redeemed, 
 (4) in case any Security is to be
redeemed in part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the Holder of such Security will receive, without charge, a new Security or Securities of authorized
denominations for the principal amount thereof remaining unredeemed, 
 (5) that, on the Redemption Date, the Redemption Price shall become
due and payable upon each such Security or portion thereof to be redeemed, and, if applicable, that interest thereon shall cease to accrue on and after said date, 
 (6) the place or places where such Securities are to be surrendered for payment of the Redemption Price and any accrued interest and Additional Amounts pertaining thereto, 
 (7) that the redemption is for a sinking fund, if such is the case, 
 (8) in the case of Securities of any series that are convertible or exchangeable into Common Stock or other securities, cash or other property, the conversion or exchange price or rate, the date or dates on which the
right to convert or exchange the principal of the Securities of such series to be redeemed will commence or terminate and the place or places where such Securities may be surrendered for conversion or exchange, and 
 (9) the CUSIP number (or any other numbers used by a Depository to identify such Securities). 
 A notice of redemption published as contemplated by Section 106 need not identify particular Registered Securities to be redeemed. 
 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. 
 Section 1105 Deposit of Redemption Price. 
 At or prior to 10:00 a.m., New York City time, on any Redemption Date, the Company shall deposit, with respect to the Securities of any series called for
redemption pursuant to 

  

 65 

 
Section 1104, 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 1003) an amount of money in the applicable Currency sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date, unless otherwise specified pursuant to Section 301 or in the
Securities of such series) any accrued interest on and Additional Amounts with respect thereto, all such Securities or portions thereof which are to be redeemed on that date. 
 Section 1106 Securities Payable on Redemption Date. 
 Notice of redemption having been given as
aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with any accrued interest
and Additional Amounts to the Redemption Date; provided, however, that, except as otherwise specified in or pursuant to this Indenture or the Registered Securities of such series, installments of interest on Registered Securities 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 Regular Record Dates therefor according to their terms and
the provisions of Section 307. 
 If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the
principal and any premium, until paid, shall bear interest from the Redemption Date at the rate prescribed therefor in the Security. 
 Section 1107
Securities Redeemed in Part. 
 Any Registered Security which is to be redeemed only in part shall be surrendered at any Office or Agency for
such Security (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in
writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Registered Security or Securities of the same series, containing identical terms and provisions, of
any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. If a Security in global form is so surrendered, the Company
shall execute, and the Trustee shall authenticate and deliver to the U.S. Depository or other Depository for such Security in global form as shall be specified in the Company Order with respect thereto to the Trustee, without service charge, a new
Security in global form in a denomination equal to and in exchange for the unredeemed portion of the principal of the Security in global form so surrendered. 
 Section 1108 Repurchases on the Open Market. 
 The Company or any Affiliate of the Company may at any time or from time to time
repurchase any of the Securities in the open market or otherwise. Such Securities may, at the option of the Company or the relevant Affiliate of the Company, be held, resold or surrendered to the Trustee for cancellation.

 ARTICLE TWELVE 
 SINKING FUNDS 
 Section 1201 Applicability of Article. 
 The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series, except as otherwise permitted or
required in or pursuant to this Indenture or any Security of such series issued pursuant to this Indenture. 
 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 such series
is herein referred to as an “optional sinking fund payment”. If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking
fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series and this Indenture. 
 Section 1202 Satisfaction of Sinking Fund Payments with Securities. 
 The Company may, in satisfaction of all or any part of
any sinking fund payment with respect to the Securities of any series to be made pursuant to the terms of such Securities (1) deliver Outstanding Securities of such series (other than any of such Securities previously called for redemption or
any of such Securities in respect of which cash shall have been released to the Company), and (2) apply as a credit Securities of such series which have been redeemed either at the election of the Company pursuant to the terms of such series of
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 sinking fund payment shall be reduced accordingly. If as a result of the delivery or credit of
Securities of any series in lieu of cash payments pursuant to this Section 1202, the principal amount of Securities of such series to be redeemed in order to satisfy the remaining sinking fund payment shall be less than $100,000, the Trustee
need not call Securities of such series for redemption, except upon Company Request, and such cash payment shall be held by the Trustee or a Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or
such Paying Agent shall at the request of the Company from time to time pay over and deliver to the Company any cash payment so being held by the Trustee or such Paying Agent upon delivery by the Company to the Trustee of Securities of that series
purchased by the Company having an unpaid principal amount equal to the cash payment requested to be released to the Company. 
  

 67 

 Section 1203 Redemption of Securities for Sinking Fund. 
 Not less than 75 days prior to each sinking fund payment date for any series of Securities, the Company shall deliver to the Trustee an Officers’
Certificate specifying the amount of the next ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting of Securities of that series pursuant to Section 1202, and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the
Trustee any Securities to be so credited and not theretofore delivered. If such Officers’ Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be
obligated to pay the amount therein specified. Not less than 60 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103
and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms
and in the manner stated in Section 1106 and Section 1107. 
 ARTICLE THIRTEEN 
 REPAYMENT AT THE OPTION OF HOLDERS 
 Section 1301
Applicability of Article. 
 Securities of any series which are repayable at the option of the Holders thereof before their Stated Maturity
shall be repaid in accordance with the terms of the Securities of such series. The repayment of any principal amount of Securities pursuant to such option of the Holder to require repayment of Securities before their Stated Maturity, for purposes of
Section 309, shall not operate as a payment, redemption or satisfaction of the Indebtedness represented by such Securities unless and until the Company, at its option, shall deliver or surrender the same to the Trustee with a directive that
such Securities be cancelled. Notwithstanding anything to the contrary contained in this Section 1301, in connection with any repayment of Securities, the Company may arrange for the purchase of any Securities by an agreement with one or more
investment bankers or other purchasers to purchase such Securities by paying to the Holders of such Securities on or before the close of business on the repayment date an amount not less than the repayment price payable by the Company on repayment
of such Securities, and the obligation of the Company to pay the repayment price of such Securities shall be satisfied and discharged to the extent such payment is so paid by such purchasers. 
 ARTICLE FOURTEEN 
 SECURITIES IN FOREIGN CURRENCIES 
 Section 1401 Applicability of Article. 
 Whenever this
Indenture provides for (i) any action by, or the determination of any of the rights of, Holders of Securities of any series in which not all of such Securities are denominated 

  

 68 

 
in the same Currency, or (ii) any distribution to Holders of Securities, in the absence of any provision to the contrary pursuant to this Indenture or
the Securities of any particular series, any amount in respect of any Security denominated in a Foreign Currency shall be treated for any such action or distribution as that amount of Dollars that could be obtained for such amount on such reasonable
basis of exchange and as of the record date with respect to Registered Securities of such series (if any) for such action, determination of rights or distribution (or, if there shall be no applicable record date, such other date reasonably proximate
to the date of such action, determination of rights or distribution) as the Company may specify in a written notice to the Trustee or, in the absence of such written notice, as the Trustee may determine. 
 ARTICLE FIFTEEN

thereafter proceed to cause the meeting to be held as provided herein, then the Company or the Holders of Securities of such series in the amount above specified, as the case may be, may determine the time and the place in the Borough of Manhattan,
The City of New York for such meeting and may call such meeting for such purposes by giving notice thereof as provided in clause (1) of this Section.

such series, be dissolved. In any other case the meeting may be adjourned for a period of not less than 10 days as determined by the chairman of the meeting prior to the adjournment of such meeting. In the absence of a quorum at any such adjourned
meeting, such adjourned meeting may be further adjourned for a period of not less than 10 days as determined by the chairman of the meeting prior to the adjournment of such adjourned meeting. Notice of the reconvening of any adjourned meeting shall
be given as provided in Section 1502(1), except that such notice need be given only once not less than five days prior to the date on which the meeting is scheduled to be reconvened. Notice of the reconvening of an adjourned meeting shall state

 Section 1505 Determination of Voting Rights; Conduct and Adjournment of Meetings. 
 (1) Notwithstanding
any other provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders of Securities of such series in regard to proof of the holding of Securities of such series and of the
appointment of proxies and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting
as it shall deem appropriate. Except as otherwise permitted or required by any such regulations, the holding of Securities shall be proved in the manner specified in Section 104 and the appointment of any proxy shall be proved in the manner
specified in Section 104. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in Section 104 or other proof. 
 (2) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company
or by Holders of Securities as provided in Section 1502(2), in which case the Company or the Holders of Securities of the series calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman
and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at the meeting. 
 (3) At any meeting, each Holder of a Security of such series or proxy shall be entitled to one vote for each $1,000 principal amount of Securities of
such series held or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of
the meeting shall have no right to vote, except as a Holder of a Security of such series or proxy. 
 (4) Any meeting of Holders of
Securities of any series duly called pursuant to Section 1502 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at
the meeting; and the meeting may be held as so adjourned without further notice. 
 Section 1506 Counting Votes and Recording Action of Meetings.

 The vote upon any resolution submitted to any meeting of Holders of Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities of such series held or represented by them. The permanent chairman
of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the permanent secretary of the meeting their verified written reports in triplicate of
all votes cast at the meeting. 

  

 71 

 
A record, at least in triplicate, of the proceedings of each meeting of Holders of Securities of any series shall be prepared by the permanent secretary of
the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice of the
meeting and showing that said notice was given as provided in Section 1502 and, if applicable, Section 1504. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy
shall be delivered to the Company, and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein
