 “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 Interest” means all additional interest then owing pursuant to the Registration Rights Agreement. 
 “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

 1 







 “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 
 (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;

 (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 FASB ASC Topic 410-20 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.

THE NOTES 

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. 

  
 30 








 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. 

  
 31 








 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), (c) or (f) hereof.

 (h) 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. 
 (i) 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 
 (C) to register the transfer
of or to exchange a Note between a record date and the next succeeding interest payment date. 

  
 43 








 (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. 
 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. 

  
 44 








 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 upon written request. 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.

REDEMPTION AND PREPAYMENT 

Section 3.01 Notices to Trustee. 
 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; 
 (2) the redemption date; 

  
 45 








 (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 (except that any Notes represented by a Global Note will be redeemed
by such method as DTC may require), 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; 
 (5) that Notes called for redemption must be surrendered to the Paying Agent to
collect the redemption price; 

  
 46 








 (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; 

(8) if the redemption is to be effected with the net cash proceeds of one or more Equity Offerings pursuant to
Section 3.07(a) hereof, a statement, if applicable, to the effect that the redemption is conditioned upon the completion of such Equity Offering(s); and 
 (9) 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, unless the condition described in the notice of redemption, to the extent one exists, does not occur. A notice of redemption may not be conditional, except that any redemption effected with the
net cash proceeds of one or more Equity Offerings as described in Section 3.07(a) hereof may, at the Company’s discretion, be conditioned upon completion of the related Equity Offering. 

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. 

  
 47 








 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.

the aggregate principal amount of the outstanding Notes accept a Change of Control Offer and the Company (or the third party making the Change of Control Offer pursuant to Section 4.14(d) hereof) purchases all of the Notes held by such Holders,
the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to Section 4.14, to redeem all of the Notes that remain outstanding following such
purchase at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on the Notes that remain outstanding, to, but not including, the date of redemption
(subject to the right of Holders on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date).

 (f) Any redemption pursuant to this Section 3.07 shall be made pursuant to the
provisions of Sections 3.01 through 3.06 hereof. 
 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: 
 (1) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10
hereof and the length of time the 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; 

  
 49 








 (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; 
 (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. 
 ARTICLE 4 
 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 thereof, holds as of 11:00 a.m. Eastern Time on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then


  
 50 








 
due. The Company shall pay all Additional Interest, if any, in the same manner on the dates and in the amounts set forth in a Registration Rights Agreement. Whenever in this Indenture there is
mentioned, in any context, principal, interest or any other amount payable under or with respect to any Notes, such mention shall be deemed to include mention of the payment of Additional Interest, to the extent that, in such context, Additional
Interest is, was or would be payable in respect thereof pursuant to paragraph 1 of the Notes, provided, however, that the Trustee shall not be deemed to have knowledge of the requirement that Additional Interest is due unless the
Trustee receives written notice from the Company stating that such amounts are due and specifying the dollar amounts thereof. 

The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the
rate equal to 1% per annum in excess of the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest
(without regard to any applicable grace period) at the same rate to the extent lawful. 
 Section 4.02 Maintenance of Office or
Agency. 
 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 office or agency or shall fail to give such notice of the location or of any change in the location thereof, such surrenders, presentations and demands may be made and
notices may be served at the designated Corporate Trust Office of the Trustee, 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. 
 (a) So long as any Notes are outstanding, the Company will file with the SEC for public availability, within 30 days of the time periods specified in the SEC rules and regulations (unless the SEC will not
accept such a filing, in which case the Company will furnish to the Holders of Notes or cause the Trustee to furnish to the Holders of Notes, within the time periods specified in the SEC’s rules and regulations): 

(1) all quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if the Company
were required to file reports, and, with respect to the annual information only, an audit report thereon by a nationally recognized firm of independent accountants; and 

  
 51 








 (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. 
 All such reports will be prepared in all material respects in
accordance with all of the rules and regulations applicable to such reports. The Company will conduct a conference call for the Holders of the Notes, any prospective investor and any securities analyst to discuss the information furnished pursuant
to the previous paragraph no later than three business days after furnishing any information pursuant to clause (1) of this Section 4.03(a). 
 If, at any time, the Company is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Company will nevertheless continue filing the reports specified in the
preceding paragraph with the SEC within the time periods specified above unless the SEC will not accept such a filing. The Company will not take any 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. 
 (b) If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries,
then, to the extent material as determined by the Board of Directors of the Company in good faith, the quarterly and annual financial information required by paragraph (a) of this Section 4.03 will include a reasonably detailed
presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the
Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company. 
 (c) For so long as any Notes remain outstanding, if at any time they are not required to file with the SEC the reports required by paragraph (a) of this Section 4.03, the Company and the
Guarantors will furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 

(d) The Company shall be deemed to have furnished such reports to the Trustee and the Holders of the Notes if it has filed such reports
with the SEC using the EDGAR filing system and such reports are publicly available. 
 (e) Delivery of such reports, information
and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the
Company’s and the Guarantors’ compliance with any of their covenants hereunder (as to which the Trustee is entitled to rely conclusively on Officers’ Certificates). The Trustee shall have no duty or responsibility to review such
reports, information or documents. 
 Section 4.04 Compliance Certificate. 

(a) The Company and each Guarantor (to the extent that such Guarantor is so required under the TIA) shall deliver to the Trustee, within
90 days after the end of each fiscal year, an Officers’ Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a
view to determining 

  
 52 








 
whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of
his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture
(or, if a Default or Event of Default has occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his
or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the
Company is taking or proposes to take with respect thereto. 
 (b) So long as any of the Notes are outstanding, the Company will
deliver to the Trustee, within five days of any Officer becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with
respect thereto. 
 Section 4.05 Taxes. 
 The Company will pay, and will cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by
appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes. 

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.

(1) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted
Payment; 
 (2) the Company would, at the time of such Restricted Payment and after giving pro forma effect
thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been 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; and

Subsidiary of the Company in such Unrestricted Subsidiary, 
 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
Prior 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.

excluded from clause (3)(B) of Section 4.07(a) hereof; 
 (3) the repurchase, redemption, defeasance or
other acquisition or retirement for value since the Issue Date of Subordinated Obligations in exchange for, or with the net cash proceeds from a substantially concurrent incurrence of, Permitted Refinancing Indebtedness;

thereby, the repurchase, redemption or other acquisition or retirement for value since the Prior Issue Date of any Equity Interests of the Company or any Restricted Subsidiary of the Company held by any of the Company’s (or any of its
Restricted Subsidiaries’) current or former directors or employees pursuant to any director or employee equity subscription agreement, stock option agreement or restricted stock agreement; provided that the aggregate price paid for all

fully satisfied its obligations under Section 4.14 (including without limitation the repurchase of all Notes validly tendered for payment in connection therewith); or 

(b) in the case of an Asset Sale, the Company has complied with and fully satisfied its obligations in accordance with

required to be valued by this Section 4.07 will be evidenced by an Officers’ Certificate delivered to the Trustee within five Business Days of the making of the Restricted Payment, together with a copy of any related resolution of the
Board of Directors of the Company. 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.

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

 57 








 
contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the 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;

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

Preferred 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 or preferred stock of a Restricted Subsidiary 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; 

(2) the incurrence by the Company and its Restricted Subsidiaries of the Existing Indebtedness;

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; 

  
 59 








 (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 

(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; 

  
 60 








 (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. 
 (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. 

  
 61 








 (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; 

(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. 

  
 62 








 (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 on a pro
rata basis 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 Notes tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds allocated for the purchase of Notes pursuant to the Asset Sale offer, the Trustee shall select the Notes to be purchased
on a pro rata basis (or, in the case of Notes represented by a Global Note, the Trustee will select Notes for purchase by such method as DTC may require). 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


  
 63 








 (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 $20.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with this Section 4.11(a); and 
 (B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $40.0 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. 
 (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; 

(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; 

  
 64 








 (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; 
 (9)
advances to or reimbursements of employees for moving, entertainment and travel expenses, drawing accounts and similar expenditures in the ordinary course of business; 

(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 ordinary course of business, except for guarantees of Indebtedness in respect of borrowed money, and (b) pledges of Equity Interests of the Company’s Unrestricted Subsidiaries for the benefit of lenders of
the Company’s Unrestricted Subsidiaries. 
 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. 

  
 65 








 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 properly tendered
prior to the expiration of the Change of Control Offer 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; 
 (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 of Control. To the extent that
the provisions of any securities laws or regulations conflict with the provisions of this 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. 

  
 66 








 (c) Promptly following the expiration of the Change of Control Offer, the Company will, to
the extent lawful, accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer, and the Company will: 
 (1) on the Change of Control Payment Date, 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 

(2) on the Change of Control Payment Date, 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. 
 On the Change of Control Payment Date, the Paying Agent will mail 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. 
 (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 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.


  
 67 








 Section 4.16 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 an
Unrestricted Subsidiary 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 4.16 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 4.16 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 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. 

Section 4.17 Termination of Covenants. 
 If on any date following the Issue Date, (1) the Notes are assigned an Investment Grade Rating from both Rating Agencies and (2) no Default or Event of Default shall have occurred and be
continuing, then the Company and its Restricted Subsidiaries will no longer be subject to the following provisions of this Indenture: 
  

	 	(i)	Section 4.07; 

  

	 	(ii)	Section 4.08; 

  

	 	(iii)	Section 4.09; 

  

	 	(iv)	Section 4.10; 

  

	 	(v)	Section 4.11; 

  

	 	(vi)	Section 4.16; and 

  

	 	(vii)	Section 5.01(4). 


Following the termination of the foregoing provisions, the Board of Directors of the Company may not designate any of its Subsidiaries as
Unrestricted Subsidiaries pursuant to Section 4.16 hereof or clause (2) of the definition of Unrestricted Subsidiary.

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 laws of the United States, any state of the United States or the District of Columbia; 
 (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, (a) be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set

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;

(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 

(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 

  
 70 








 
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 
 (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 

  
 71 








 (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. 
 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. 

  
 72 








 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,

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

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, 

  
 73 








 
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.

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. 

  
 74 








 (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. 
 (d) Whether or not therein expressly so provided, every
provision of this Indenture 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. 
 (g) The Trustee shall not be deemed to have notice, nor shall it be charged
with knowledge, of any Default or Event of Default unless a Responsible Officer has actual knowledge thereof or unless written notice of such Default or Event of Default is received by the Trustee at the Corporate Trust Office of the Trustee, and
such notice references the Notes and this Indenture. 
 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. 

  
 75 








 (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 and 7.11 hereof. 
 Section 7.04 Trustee’s Disclaimer. 

The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it
shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it will not be responsible for the use or application of
any money received by any Paying Agent other than the Trustee, and it will not be 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 Default in payment of principal of, premium, if any, 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. 

  
 76 








 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 express trust. The Company will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such
expenses will include the reasonable 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 the Company and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Company, the Guarantors, any Holder or any other Person) or
liability in connection with the exercise or performance of 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. 
 (c) The obligations of the Company and the Guarantors under this Section 7.07
will survive the satisfaction and discharge of this Indenture. 
 (d) To secure the Company’s and the Guarantors’
payment obligations in this Section 7.07, the Trustee will have a Lien 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. 
 (f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the extent applicable.


  
 77 








 Section 7.08 Replacement of Trustee. 

(a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor
Trustee’s acceptance of appointment as provided in this Section 7.08. 
 (b) The Trustee may resign in writing at any
time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing.
The Company may remove the Trustee if: 
 (1) the Trustee fails to comply with Section 7.10 hereof;

 (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 the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 

(e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with
Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 (f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee will become
effective, and the successor Trustee will 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. 

Section 7.09 Successor Trustee by Merger, etc. 
 If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act will
be the successor Trustee.

million as set forth in its most recent published annual report of condition. 
 This Indenture will always have a Trustee who

 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; 
 (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 

  
 79 








 (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 

(B) since the Issue Date, there has been a change in the applicable federal income tax law, 

  
 80 








 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. 
 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


  
 81 








 
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

(7) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture as of
the date hereof;

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. 

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 

  
 83 








 
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. 
 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. 

  
 84 








 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 
 (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. 

  
 85 








 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. 

  
 86 








 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 4.15 hereof, the Company will cause such Domestic Subsidiary to comply with the provisions of Section 4.15 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) such transaction complies 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 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. 

  
 87 








 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, to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, then the Person acquiring the property will be released and relieved of any
obligations under its Note Guarantee; provided that such transaction does not violate 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) In the event of any sale or other disposition of the Capital Stock of any Guarantor, to a Person that is not
(either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, then such Guarantor will be released and relieved of any obligations under its Note Guarantee; provided that (i) such
transaction does not violate Section 4.10 hereof and (ii) such Guarantor ceases to be a Subsidiary of the Company as a result of such sale or other disposition. 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. 
 (c) 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. 
 (d) 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. 
 (e) Upon the liquidation or dissolution of a Guarantor;
provided that no Default or Event of Default has occurred and is continuing, such 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. 

  
 88 








 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 
 (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. 

  
 89 








 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.

price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest [and Additional Interest, if any,]15 thereon to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest [and

the Note Guarantees may be amended or supplemented: to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s or a
Guarantor’s obligations to Holders of the Notes and Note Guarantees in case of a merger or consolidation, 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 under the Indenture of any such Holder, to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA, to conform the text of the Indenture or the Notes to any provision of
the “Description of Notes” section of the Company’s Offering Memorandum dated June 3, 2011, 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 the Indenture, the Note Guarantees or the Notes, to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture, or to allow any Guarantor to execute a

Indenture or the Notes; (v) default under certain other agreements relating to Indebtedness for money borrowed of the Company or any of its Restricted Subsidiaries, which default results in
the acceleration of such Indebtedness prior to its express maturity; (vi) certain final judgments for the payment of money that remain undischarged for a period of 60 days; (vii) certain events of bankruptcy or insolvency with respect to
the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary; and (viii) except as permitted by the 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 any Guarantor or any Person acting on its behalf denies or disaffirms its obligations under such
Guarantor’s Note Guarantee. If any 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 the Notes to be due and payable immediately.
Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the
Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the 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 [or Additional Interest]19, 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 [or Additional Interest]20, if any, on, or the principal of, the Notes. The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required, upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 

(13) TRUSTEE DEALINGS WITH COMPANY. The
Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. 

(14) NO RECOURSE AGAINST OTHERS. A
director, officer, employee, incorporator, member, partner or stockholder of the Company or any of the Guarantors, as such, will not have any liability for any obligations of the Company or the Guarantors under the Notes, the Note Guarantees, the
Indenture or the Registration Rights Agreement 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 part of
the consideration for the issuance of the Notes.
