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

The place of payment with respect to the Notes, in addition to the Corporate Trust Office of the Trustee, shall be an office maintained by the Company in 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 7.06 to compensate and indemnify the Trustee shall extend likewise to each Agent. 

Section 2.04 Paying Agent to Hold Money in Trust. 

The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit
of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or Cash 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. 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.

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

If any mutilated Note is surrendered to the Trustee or the Company and the Trustee and the Company receive evidence to their 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 to protect the Trustee, and the Company to protect the Company, the Guarantors, the Trustee, any Agent and any authenticating agent from any loss that

satisfactory to each of them that the replaced Note is held by a protected purchaser.

 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.

 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 and the Trustee’s customary procedures). 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 delivered at least 5 Business Days before such
notice is to be sent, the Trustee in the name and at the expense of the Company) will send or cause to be sent to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 

Section 2.13 PIK Interest. 
 Except as set
forth in the following sentence and in Section 1 of the Notes, interest on the Notes shall be payable entirely in Cash Interest at the Cash Interest Rate. For any interest period ending on or prior to the November 15, 2017 Interest Payment
Date, the Company may elect to pay all or any portion of interest in kind at the PIK Interest Rate on the then outstanding principal amount of the Notes (a “PIK Payment”) by increasing the principal amount of the outstanding Notes
or by issuing additional Notes (each, a “PIK Interest Note”) in a principal amount equal to such interest (“PIK Interest”); provided, that the November 15, 2016 interest payment shall be made entirely in PIK
Interest at the PIK Interest Rate. On the May 15, 2018 Interest Payment Date, the Company shall be permitted to make only part of the interest payment in PIK Interest at 

  
 55 

 
the PIK Interest Rate and part of the interest payment in Cash Interest at the Cash Interest Rate, provided, that PIK Interest to be paid on such Interest Payment Date shall accrue only
for the period from November 15, 2017 to, but not including, March 7, 2018, and any remaining interest for such period shall be payable solely in Cash Interest. 

Notwithstanding anything to the contrary, the payment of accrued interest in connection with any redemption or repurchase of the Notes as
described under Section 3.07, 4.12, 4.15 or 4.16 hereof will be made solely in Cash Interest. If the Company elects to pay interest on the Notes as a combination Cash Interest and PIK Interest, such Cash Interest and PIK Interest shall be paid
on the Notes on a pro rata basis. In the event that the Company shall elect to pay PIK Interest for any interest period, then the Company shall deliver a notice to the Trustee and the Holders not less than five Business Days prior to the
commencement of the relevant interest period, which notice shall state the total amount of interest to be paid on such Interest Payment Date and the total amount of PIK Interest. 

Unless otherwise agreed between the Company and the Trustee, with respect to the issuance of any PIK Interest Notes, the Company shall deliver
to the Trustee no later than two Business Days prior to the applicable Interest Payment Date, (i) if such PIK Interest Notes are Definitive Notes, the required amount of new Definitive Notes (rounded up to the nearest whole dollar) and an
Authentication Order to authenticate and deliver such PIK Interest Notes on the relevant Interest Payment Date or (ii) if such PIK Interest Notes are Global Notes, by delivering a written order from an Officer of the Company to the Trustee to
increase the principal amount of the outstanding Global Note by an amount equal to the amount of PIK Interest for the applicable interest period (rounded up to the nearest whole dollar). 

Any PIK Interest Note shall, after being executed and, if applicable, authenticated pursuant to Section 2.02 hereof, be (i) if such
PIK Interest Notes are Definitive Notes, mailed to the Person entitled thereto as shown on the register for the Definitive Notes as of the relevant Record Date or (ii) if such PIK Interest Notes are Global Notes, deposited into the account
specified by the Holder or Holders thereof as of the relevant record date. 
 Notwithstanding the foregoing, in connection with any PIK
Payment on Notes that are Global Notes, the Company may, if requested in writing by any Holder or if required by the procedures of the Depositary, in lieu of increasing the principal amount of such Global Notes, issue the required amount of the PIK
Payment in the form of a new Global Note (rounded up to the nearest whole dollar) upon delivery to the Trustee of an Authentication Order to authenticate and deliver such new Global Note on the relevant Interest Payment Date. 

Any PIK Payment shall be made in such form and on terms as specified in this Section 2.13, and the Company shall and the Trustee and
Paying Agent may take additional steps as necessary to effect such PIK Payment.

 ARTICLE 3 

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; 
 (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 (or send electronically in the case of Global Notes), a notice of redemption to each Holder whose Notes are to be redeemed at its registered address (with a copy to the Trustee), except that redemption
notices may be sent 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 Article 8 or 11 hereof. 

  
 57 

 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; 
 (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 a copy of the notice of
redemption that sets 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 sent 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 pursuant to 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 (which amount, for the avoidance of doubt, shall be deposited in cash) 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. 

  
 58 

 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 (which amount, for the avoidance of doubt, shall be deposited in cash). If
any Note called for redemption or tendered for purchase is not so paid upon surrender for redemption or purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the
redemption or tendered for purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 

Section 3.06 Notes Redeemed or Purchased in Part. 

Upon surrender of a Note that is redeemed or purchased in part, the Company will issue and, upon receipt of an Authentication Order, the
Trustee will authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered. 

Section 3.07 Optional Redemption. 
 (a) At any time
prior to May 15, 2017, the Company may on any one or more occasions redeem up to 35% of the aggregate original principal amount of Notes issued under this Indenture at a redemption price of 109.000% of the principal amount thereof, plus accrued
and unpaid interest to, but not including the redemption date (subject to the right of Holders on the relevant record date to receive interest due on an Interest Payment Date that is not on or prior to the redemption date), with an amount of cash
not greater than the net cash proceeds of one or more Equity Offerings; provided that: 
 (1) at least 65% in aggregate principal amount of Notes
originally issued under this Indenture remains outstanding immediately after the occurrence of such redemption; and 
 (2) each such redemption must occur
within 90 days of the date of the closing of the related Equity Offering.

(d) or (e) below, the Notes will not be redeemable at the Company’s option prior to May 15, 2017. 
 (c) On or after May 15, 2017,
the Company may redeem all or a part of the Notes upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest on the Notes
redeemed to, but not including, the applicable redemption date, if redeemed during the twelve-month period beginning on May 15 of the years indicated below, subject to the rights of Holders on the relevant record date to receive interest on the
relevant Interest Payment Date: 
  

					
	 Year

	 2017
	  	 	104.500	% 
	 2018
	  	 	102.250	% 
	 2019 and thereafter
	  	 	100.000	% 

  
 59 

 (d) At any time prior to May 15, 2017, the Company may also redeem all or a part of the Notes, upon not less
than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but not including, the date of redemption,
subject to the rights 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. 

(e) In the event that Holders of not less than 90% of 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 4.15(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 to the
Holders and the Trustee, given not more than 30 days following the purchase pursuant to Section 4.15 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 Section 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 4.12 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 in right of payment 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 based on the outstanding amount of the Notes and such other Indebtedness that is pari passu with the Notes, 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. 

  
 60 

 For the avoidance of doubt, each Asset Sale Offer shall be made to the Holders and to any
applicable Other Offer Parties pursuant to Section 4.12 and the aggregate amount of the Notes subject to any Asset Sale Offer that is also made to Other Offer Parties shall be an amount of Excess Proceeds that is proportionate to the then
aggregate outstanding principal amount of the Notes relative to the then outstanding principal amount of relevant Indebtedness of the Other Offer Parties. In addition, if the offer requirements or mechanics applicable to such other Indebtedness are
not consistent with the procedures set forth in this Section 3.09 for an Asset Sale Offer, the Company may change the procedures for such Asset Sale Offer from those set forth herein provided that (x) no change may be made with respect to
the amount of Notes subject to the Asset Sale Offer and (y) such procedures shall be clearly set out in the relevant Asset Sale Offer notice. 

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 (or electronically in the case of Global Notes), 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 4.12 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; 
 (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 and 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; 

  
 61 

 (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 the Company or the trustee or agent for such other pari passu Indebtedness will select such 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 or $1.00 or an integral multiple thereof in the case of any PIK Interest Notes, 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 Section 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 Cash 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 

  
 62 

 
pay all principal, premium, if any, and interest then due. Any PIK Payment shall be considered paid on the date it is due (a) if PIK Interest Notes (including PIK Interest Notes that are
Global Notes) have been issued therefor, such PIK Interest Notes have been executed by the Company and authenticated by the Trustee on or prior to the date the payment is due in accordance with the terms of this Indenture and (b) if the PIK
Payment is made by increasing the principal amount of Global Notes then authenticated, the Company has delivered the written request required by Section 2.13 and the Trustee has increased the principal amount of Global Notes then authenticated
by the relevant amount on or prior to the date the payment is due. 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 made. 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 at the Corporate Trust Office of the Trustee; provided that the Corporate Trust Office of the Trustee shall not be an office or agency of the Company for the purpose of service of legal
process against the Company or any Guarantor. 
 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, notices and demands may be made 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; provided that the Corporate Trust Office of the Trustee shall not be an office or agency of the Company for the purpose of service of legal process against the Company or any
Guarantor.

(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,

(c) 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 above 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.

Company were required to file those reports with the SEC.

its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company. 
 (e) 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. 

(f) 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. The Trustee shall have no responsibility to determine whether such filing has occurred or if such reports are publicly available. 

  
 64 

 (g) 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 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

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.

Subordinated Obligation (excluding the purchase or other acquisition of any Subordinated Obligation in anticipation of satisfying a sinking fund obligation, principal installment or final maturity payment, in each case due within one year of the
date of purchase or other acquisition); or 
 (4) make any Restricted Investment (all such payments and other actions set forth in clauses (1) through

assets or securities that are required to be valued by this Section 4.09 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 4.09. For purposes of determining compliance with this Section 4.09, 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 4.09, 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 4.09.

consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

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; 

  
 70 

 (2) this Indenture, the Notes, the Note Guarantees and the other Note Documents; 

(3) applicable law, rule, regulation, order, approval, permit or similar restriction; 

(4) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time
of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in 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; 
 (6) purchase money obligations for property (including Capital Stock) acquired in the ordinary course of business,
Capital Lease Obligations and mortgage financings that impose restrictions on the property purchased or leased of the nature described in clause (3) of Section 4.10(a) hereof; 

(7) any agreement for the sale or other disposition of assets, including without limitation an agreement for the sale or other disposition of the Capital Stock

to the assets or property that are the subject of such agreements; 
 (10) other Indebtedness of the Company or any of its Restricted Subsidiaries permitted
to be incurred pursuant to an agreement entered into subsequent to the Issue Date in accordance with Section 4.11; provided that the provisions of such agreement relating to such dividend and other payment encumbrances or restrictions

the Existing Term Loan Agreement, the 1.5 Lien Term Loan Agreement and the New Third Lien Notes Indenture, in each case as in effect on the Issue Date; 

  
 71 

 (11) the issuance of preferred stock by a Restricted Subsidiary or the payment of dividends thereon in accordance
with Section 4.11 and the terms thereof; provided that issuance of such preferred stock was made in accordance and the terms of such preferred stock do not expressly restrict the ability of a Restricted Subsidiary to pay dividends or
make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such preferred stock prior to paying any dividends or making any other distributions on such other Capital Stock);

 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Company
will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company and the Restricted Subsidiaries may incur Indebtedness (including
Acquired Debt) or issue Disqualified Stock or preferred stock of a Restricted Subsidiary, if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred stock of a Restricted Subsidiary is issued, as the case may be, would have been at least 2.0 to 1.0, determined on a pro forma
basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock 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 4.11(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: 
 (i) $800.0 million; and 

(ii) 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; 

  
 72 

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

(3) the incurrence by the Company and the Guarantors of Indebtedness represented by (a) the Notes and the related Note Guarantees to be issued on the
Issue Date (including any increase in principal amount as a result of a PIK Payment and any PIK Interest Notes in respect thereof) and (b) the New Third Lien Notes and the related guarantees thereof issued on the Issue Date (including any
increase in principal amount and any PIK interest notes in respect thereof, in each case as a result of a PIK payment); 
 (4) the incurrence by the Company
or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of
design, construction, installation or improvement of property, plant or equipment used in the business of the Company or any of its Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred
to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed $50.0 million at any time outstanding; 

(5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which
are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under Section 4.11(a) hereof or clauses (2), (3), (4) or
(11) of this Section 4.11(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); 

  
 73 

 (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 or 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 4.11; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes,
then the Guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed; 
 (11) Permitted Acquisition
Indebtedness; 
 (12) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other
financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days; 

(13) Indebtedness consisting of the financing of insurance premiums in customary amounts consistent with the operations and business of the Company and its
Restricted Subsidiaries; 
 (14) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from agreements of the Company
or any of its Restricted Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any business, assets or Capital Stock of a Subsidiary,
provided that the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds actually received by the Company and its Restricted Subsidiaries in connection with such disposition; 

(15) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of bid, performance, surety and similar bonds issued for
the account of the Company and any of its Restricted Subsidiaries in the ordinary course of business, including guarantees and obligations of the Company or any of its Restricted Subsidiaries with respect to letters of credit supporting such
obligations (in each case, other than an obligation for money borrowed); and 

  
 74 

 (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) Notwithstanding the foregoing, the
Company and its Restricted Subsidiaries will not incur any Indebtedness secured by a Priority Lien unless the principal amount of such Indebtedness is pari passu in right of payment with the principal amount of all other Indebtedness secured
by a Priority Lien. For purposes of determining compliance with this Section 4.11, 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 4.11(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 4.11; provided that any Indebtedness outstanding on the Issue Date incurred under the Existing Revolving Credit Agreement and the 1.5 Lien Term Loan Agreement shall be considered
incurred under clause (1) of the definition of Permitted Debt and may not be later reclassified. 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 4.11; 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 4.11, the maximum
amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.11 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. 

(e) The amount of any Indebtedness outstanding as of any date will be: 

(1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount; 

(2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and 

(3) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of: 

(A) the Fair Market Value of such asset at such date of determination; and 

(B) the amount of the Indebtedness of the other Person. 

  
 75 

 Section 4.12 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 4.12; and 

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

(b) Within 360 days after the receipt of any Net Proceeds from an Asset Sale, or, if the Company has entered into a binding commitment or commitments with
respect to the actions described in clause (2) or (3) below, within 540 days after the receipt of any Net Proceeds from an Asset Sale, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds:

 (1) (A) if the Asset Sale is a Collateral Disposition, to repay, prepay, redeem or repurchase Priority Lien Debt, the Notes and other outstanding
Parity Lien Debt; provided that with respect to Parity Lien Debt, such repayment, prepayment, redemption or repurchase must be made either by a pro rata redemption or repayment of outstanding Parity Lien Debt or by an offer to purchase on a pro rata
basis made to all holders of Parity Lien Obligations under the procedures set forth in Section 3.09 or (B) if such Asset Sale is not a Collateral Disposition, to repay, prepay, redeem or repurchase Indebtedness of the Company or another
Restricted Subsidiary that is not subordinated in right of payment to the Notes (but, in each case, excluding intercompany Indebtedness of the Company or any Restricted Subsidiary or any of its Affiliates); 

  
 76 

 (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 4.12(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 (i) with respect to Excess Proceeds from any Asset Sale that is a
Collateral Disposition, all holders of other Parity Lien Obligations, or (ii) with respect to other Excess Proceeds, all holders of other Indebtedness that is pari passu in right of payment with the Notes (with a copy to the Trustee)
containing provisions similar to those set forth in this Indenture (such applicable holders of any Parity Lien Obligations or other applicable pari passu Indebtedness, the “Other Offer Parties”) with respect to offers to
purchase, repay or redeem with the proceeds of sales of assets in accordance with Section 3.09 hereof to purchase or repay on a pro rata basis the maximum principal amount of Notes and such other pari passu Indebtedness that may be
purchased or repaid 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 or repayment, 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 4.12, 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 4.12 by virtue of such compliance. 

Section 4.13 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 

  
 77 

 (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 4.13(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 this Section 4.13 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 4.13(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 4.09 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; 

  
 78 

 (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 4.13(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 exchange offer 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 4.14 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 Indebtedness of the Company or any Guarantor. 

Section 4.15 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 

  
 79 

 
“Change of Control Payment”). Within thirty days following any Change of Control, the Company will send a notice to each Holder (with a copy to the Trustee) 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 4.15 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 repurchased 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 4.15 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 4.15 by virtue of such compliance. 
 (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 

  
 80 

 (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 send 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 (or $1.00 or an integral multiple thereof in the case of any PIK Interest Notes). 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 4.15, 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 4.15 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 canceled, 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 4.16 Offer to Repurchase Upon Triggering
Event. 
 (a) Upon the occurrence of a Triggering Event (as defined below), each Holder of the Notes will have the right to require the Company to make
an offer (a “Triggering Event Repurchase 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 100% of the aggregate principal
amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased to the date of repurchase (the “Triggering Event Purchase Date”), subject to the rights of Holders on the relevant record date to receive
interest due on an Interest Payment Date that is on or before the Triggering Event Purchase Date (the “Triggering Event Payment”). Within thirty days following any Triggering Event, the Company will mail a notice to each Holder
(with a copy to the Trustee) describing the Triggering Event, offering to repurchase the Notes as of the Triggering Event Purchase Date and stating: 
 (1)
that the Triggering Event Repurchase Offer is being made pursuant to this Section 4.16 and that all Notes properly tendered prior to the expiration of the Triggering Event Repurchase Offer will be accepted for payment; 

  
 81 

 (2) the purchase price and the Triggering Event Purchase Date, which shall be no earlier than 30 days and no
later than 60 days from the date such notice is mailed; 
 (3) that any Note not repurchased will continue to accrue interest; 

(4) that, unless the Company defaults in the payment of the Triggering Event Payment, all Notes accepted for payment pursuant to the Triggering Event
Repurchase Offer will cease to accrue interest after the Triggering Event Purchase Date; 
 (5) that Holders electing to have any Notes purchased pursuant to
a Triggering Event Repurchase 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

 (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 Triggering Event Purchase Date, a telegram, telex, facsimile transmission or letter setting forth

(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) A “Triggering
Event” will be deemed to occur (i) on the 30th day prior to the stated maturity date of the Existing Senior Unsecured Notes outstanding on the Issue Date, if on such date the aggregate outstanding principal amount of all Existing
Senior Unsecured Notes that shall not have been repurchased, redeemed, discharged, defeased or called for redemption (with funds to effect such redemption deposited with the trustee for such Existing Senior Unsecured Notes or otherwise set aside for
purposes of such redemption), exceeds $50.0 million. 
 (c) 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 Triggering Event Repurchase Offer. To the extent that the provisions of any securities laws or regulations conflict with the

Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company.

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 new Note will be in a
principal amount of $1,000 or an integral multiple of $1,000 in excess of $1,000. Any Note so accepted for payment will cease to accrue interest on and after the Triggering Event Purchase Date unless the Company defaults in making the Triggering
Event Payment. The Company will publicly announce the results of the Triggering Event Repurchase Offer on or as soon as practicable after the Triggering Event Purchase Date. 

Section 4.17 Designation of Restricted and Unrestricted Subsidiaries. 

The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not
cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as 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 4.09 hereof or under one or more clauses of the definition of Permitted
Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. 

Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a
certified copy of a resolution of the Board of Directors giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions of this Section 4.17 and was permitted by
Section 4.09 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements of this Section 4.17 as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of
this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.11 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 

  
 83 

 
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 4.11 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 4.18 Additional Note Guarantees and Collateral. 

(a) If, after the Issue Date, any Domestic Subsidiary (other than an Excluded 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 (i) become a Guarantor by executing and delivering a supplemental indenture in
the form attached hereto as Exhibit E and (ii) execute and deliver to the Collateral Trustee and the Trustee an amendment, supplement or other instrument in respect of the other Security Documents in form reasonably satisfactory to the
Collateral Trustee necessary to cause such Domestic Subsidiary to become a grantor thereunder and take all action required thereunder to perfect the Liens created thereunder, as well as to execute and deliver to the Collateral Trustee and the
Trustee joinders to the Intercreditor Agreement and the Collateral Trust Agreement, in each case within 180 days of the date on which it guaranteed such Indebtedness. 

(b) The Company and each of the Guarantors shall do or cause to be done all acts and things that may be required, or that the Collateral Trustee from time to
time may reasonably request, to assure and confirm that the Collateral Trustee holds, for the benefit of the holders of Parity Lien Obligations, duly created and enforceable and perfected Liens upon the Collateral (including any acquired Property or
other Property required by any Parity Lien Document to become, Collateral after the Issue Date), in each case, as contemplated by, and with the Lien priority required under, the Parity Lien Documents, and in connection with any merger, consolidation
or sale of assets of the Company or any Guarantor, the property and assets of the Person which is consolidated or merged with or into the Company or any Guarantor, to the extent that they are property or assets of the types which would constitute
Collateral under the Security Documents, shall be treated as after-acquired property and the Company or such Guarantor shall take such action as may be reasonably necessary to cause such property and assets to be made subject to the Parity Liens, in
the manner and to the extent required under the Parity Lien Documents. 
 (c) Upon the reasonable request of the Collateral Trustee or any Parity Lien
Representative at any time and from time to time, the Company and each of the Guarantors shall promptly execute, acknowledge and deliver such Security Documents, instruments, certificates, financing statements, notices and other documents, and take
such other actions as shall be reasonably required, or that the Collateral Trustee may reasonably request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred, in each case as contemplated by the Parity
Lien Documents for the benefit of the holders of Parity Lien Obligations; provided, that no such Security Document, instrument or other document shall be materially more burdensome upon the Company and the Guarantors than the Parity Lien Documents
executed and delivered (or required to be executed and delivered promptly after the date of this Indenture) by the Company and the Guarantors in connection with the transactions contemplated by the Existing Term Loan Agreement. 

  
 84 

 (d) In addition to the Collateral, from and after the Issue Date, if the Company or any Guarantor acquires any
Property that constitutes collateral for the Priority Lien Debt or Junior Lien Debt, if and to the extent that any Priority Lien Document or Junior Lien Document, as applicable, requires any supplemental security document for such collateral or
other actions to achieve a perfected Lien on such collateral, the Company shall, or shall cause the applicable Guarantor to, promptly (but not in any event no later than the date that is 20 Business Days after which such supplemental security
documents are executed and delivered (or other action taken) under such Priority Lien Documents or Junior Lien Documents, as applicable), to the extent permitted by applicable law, execute and deliver to the Collateral Trustee appropriate Security
Documents (or amendments thereto) in such form as shall be necessary to grant the Collateral Trustee a valid and enforceable perfected Lien on such Collateral or take such other actions in favor of the Collateral Trustee as shall be reasonably
necessary to grant a valid and enforceable perfected Lien on such Collateral to the Collateral Trustee, for the benefit of Holders of the Notes and the holders of any other Parity Lien Obligations, subject to the terms of this Indenture, the
Intercreditor Agreement and the other Note Documents. Additionally, subject to this Indenture, the Intercreditor Agreement and the other Note Documents, if the Company or any Guarantor creates any additional Lien upon any Property that would
constitute Collateral, or takes any additional actions to perfect any existing Lien on Collateral, in each case for the benefit of the holders of the Priority Lien Debt or the holders of Junior Lien Debt, after the Issue Date, the Company or such
Guarantor, as applicable, must, to the extent permitted by applicable law, within 20 Business Days after such Lien is granted or other action taken, grant a valid and enforceable perfected Lien upon such property or asset, or take such
additional perfection actions, as applicable, and obtain all related deliverables as those delivered to the Priority Lien Representative or Junior Lien Collateral Agent, as applicable, in each case as security for the Obligations. Notwithstanding
the foregoing, to the extent that any Lien on any Collateral is perfected by the possession or control of such Collateral or of any account in which such Collateral is held, and if such Collateral or any such account is in fact in the possession or
under the control of the Priority Lien Representative, or of agents or bailees of the Priority Lien Representative, the perfection actions and related deliverables described in this Section 4.18(d) shall not be required. 

(e) The Company will deliver to the Collateral Trustee semi-annually on or before March 1 and September 1 in each calendar year, beginning
March 1, 2017, an Officers’ Certificate certifying that, as of the date of such certificate, the Collateral includes Oil and Gas Properties that include not less than 80% (or such greater amount as may be required by the Existing Revolving
Credit Agreement in effect at such time) of the total discounted present value of Proved Reserves attributable the Oil and Gas Properties of the Company and its Restricted Subsidiaries, as evaluated in the most recent Reserve Report, after giving
effect to exploration and production activities, acquisitions, dispositions and production since the date of such Reserve Report (the “Minimum Mortgage Requirement”), together with (i) such executed Mortgages or amendments or
supplements to prior Mortgages naming the Collateral Trustee, as mortgagee or beneficiary, as may be necessary to cause the Minimum Mortgage Requirement to be satisfied, (ii) reasonably satisfactory evidence of the completion of all recordings
and filings of such Mortgages, amendments or supplements in the proper recorders’ offices or appropriate public records (and 

  
 85 

 
payment of any taxes or fees in connection therewith) and (iii) local counsel opinion or opinions (each, subject to customary assumptions and qualifications) to the effect that the
Collateral Trustee has a valid and perfected Lien with respect to the real property that is subject to the applicable Mortgage; provided that, (x) to the extent corresponding mortgages securing the Priority Lien Obligations are being delivered
and (y) Mortgages have previously been recorded in the public records of the county or counties applicable to such additional Mortgages or amendments or supplements to prior Mortgages, no such opinion shall be required unless a corresponding
opinion will be delivered to the Priority Lien Agent. The certificate referred to in this Section 4.18(e) shall include a schedule tied to the Reserve Report identifying those properties treated in the Reserve Report as Collateral from those
properties treated in the Reserve Report which are not Collateral and may be the same certificate delivered to the Administrative Agent under the Existing Term Loan Agreement. 

(f) Notwithstanding anything herein or in the Note Documents to the contrary, neither the Company nor any Guarantor will be required to grant a security
interest in, and the Collateral shall not include, any Excluded Asset. 
 Section 4.19 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 4.09; 
 (ii)
Section 4.10; 
 (iii) Section 4.11; 

(iv) Section 4.12; 
 (v)
Section 4.13; 
 (vi) Section 4.17; 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 4.17 hereof or clause (2) of the definition of Unrestricted Subsidiary. 
 The
Trustee shall have no duty to monitor whether or not the Notes have been assigned an Investment Grade Rating, nor any duty to notify the Holders of any of the foregoing.

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 Section 3.09, 4.12, 4.15, 4.16 or 5.01 hereof; 

(4) failure by the Company or any of its Restricted Subsidiaries for 60 days after notice to the Company by the Trustee or the Holders of at least 25% in
aggregate principal amount of the Notes then outstanding voting as a single class to comply with any of the other agreements in this Indenture; 

  
 88 

 (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 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,

(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 

  
 89 

 (C) orders the liquidation of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary
or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; and the order or decree remains unstayed and in effect for 60 consecutive days; and 

(9) the occurrence of any of the following: 
 (A) except as
permitted by the Note Documents, any Security Document establishing the Parity Liens ceases for any reason to be enforceable; provided that it will not be an Event of Default under this clause (9)(A) if the sole result of the failure of one or
more Security Documents to be fully enforceable is that any Parity Lien purported to be granted under such Security Documents on Collateral, individually or in the aggregate, having a fair market value of not more than $15.0 million, ceases to be
enforceable; provided further that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 45 days after any officer of the Company or any Restricted Subsidiary becomes aware of such failure, which failure
has not been cured during such time period; 
 (B) except as permitted by the Note Documents, any Parity Lien purported to be granted under any Security
Document on Collateral, individually or in the aggregate, having a fair market value in excess of $15.0 million, ceases to be an enforceable and perfected second-priority Lien, subject only to Permitted Liens and the terms of the Intercreditor
Agreement; provided that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 45 days after any officer of the Company or any Restricted Subsidiary becomes aware of such failure, which failure has not
been cured during such time period; 
 (C) the Company or any Guarantor, or any Person acting on behalf of any of them, denies or disaffirms, in writing, any
obligation of the Company or any Guarantor set forth in or arising under any Note Document establishing Parity Liens; and 
 (D) except as permitted by any
Note Document, (i) 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 (ii) 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. 

 

  
 90 

 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. 
 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; 

  
 91 

 (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
bring suit for the enforcement of payment of principal, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), shall not be impaired or affected
without the consent of such Holder. 
 Section 6.08 Collection Suit by Trustee. 

If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover
judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium, if any, and interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest
and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

Section 6.09 Trustee May File Proofs of Claim. 

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any
other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 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 7.06 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

  
 92 

 
or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization,
arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 6.10 Priorities. 
 If the
Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order: 
 First: to the Trustee, its agents and
attorneys for amounts due under Section 7.06 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest ratably, without preference or
priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively; and 
 Third:
to the Company or to such party as a court of competent jurisdiction shall direct. 
 The Trustee may fix a record date and payment date for
any payment to Holders of Notes pursuant to this Section 6.10. 
 Section 6.11 Undertaking for Costs. 

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted
by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’
fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant
to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes. 
 ARTICLE 7

 TRUSTEE 
 Section 7.01 Duties of
Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 

(b) Except during the continuance of an Event of Default: 
 (1)
the duties of the Trustee will be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations
shall be read into this Indenture against the Trustee; and 

  
 93 

 (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 paragaph 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), (c) and (e) 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. 
 (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. 

  
 94 

 (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 indemnity or security satisfactory to the Trustee against
the losses, liabilities and expenses that might be incurred by it in compliance with such request or direction. 
 (g) In no event shall the Trustee be
responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or
damage and regardless of the form of action. 
 (h) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without
limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder (including, without limitation, as Collateral Trustee), and each Agent. 

(i) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder. 

(j) The Trustee shall not be bound to make any investigation into (i) the performance of or compliance with any of the covenants or agreements set forth
herein, (ii) the occurrence of any default, or the validity, enforceability, effectiveness or genuineness of this Indenture or any other agreement, instrument or document. 

(k) The Trustee shall not be responsible or liable for any failure or delay in the performance of its obligations under this Indenture arising out of or
caused, directly or indirectly, by circumstances beyond its reasonable control, including, without limitation, acts of God; earthquakes; fire; flood; terrorism; wars and other military disturbances; sabotage; epidemics; riots; interruptions; loss or
malfunction of utilities, computer (hardware or software) or communication services; accidents; labor disputes; and acts of civil or military authorities and governmental action. 

(l) The permissive rights of the Trustee under this Indenture shall not be construed as duties. 

  
 95 

 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 Section 7.09 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 actually known to a Responsible Officer of the Trustee, the Trustee will send to Holders of Notes a notice of the Default or Event of Default within 90 days after it is actually known to the
Trustee. 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 the Trustee in good faith determines that withholding the
notice is in the interests of the Holders of the Notes. 
 Section 7.06 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 jointly and severally 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 7.06) 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

  
 96 

 
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 7.06 will survive the satisfaction and discharge of this Indenture or the
resignation or removal of the Trustee. 
 (d) To secure the Company’s and the Guarantors’ payment obligations in this Section 7.06, 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 6.01(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. 

Section 7.07 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 7.07. 

(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 7.09 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. 

  
 97 

 (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 7.09 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 7.06 hereof. Notwithstanding replacement
of the Trustee pursuant to this Article 7, the Company’s obligations under Section 7.06 hereof will continue for the benefit of the retiring Trustee. 

Section 7.08 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. 
 Section 7.09 Eligibility; Disqualification.

 There will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of
America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $100.0
million as set forth in its most recent published annual report of condition. 
 This Indenture will always have a Trustee who satisfies the
requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b). 
 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 

  
 98 

 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 
 (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, 4.17 and 4.18 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 

  
 99 

 
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, Section 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 (in each case assuming the payment of interest as Cash Interest through such 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, 

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; 

  
 100 

 (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. 
 All of the Collateral will be released from the Lien securing the Notes, as
provided under Section 13.05 hereof, upon a Legal Defeasance or Covenant Defeasance in accordance with the provisions described above. 

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 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. 

Subject to applicable abandoned property laws, 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 

  
 101 

 
thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, will thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that
such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company. 

Section 8.07 Reinstatement. 
 If the
Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had
occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the
Company makes any payment of principal of, premium, if any, or interest on, any Note following the reinstatement of its obligations, the Company will be subrogated to the rights of the Holders of such Notes to receive such payment from the money
held by the Trustee or Paying Agent. 
 ARTICLE 9 

AMENDMENT, SUPPLEMENT AND WAIVER 

Section 9.01 Without Consent of Holders of Notes. 

Notwithstanding Section 9.02 of this Indenture, the Company, the Guarantors, the Trustee and the Collateral Trustee (if applicable with
respect to the Security Documents) may amend or supplement this Indenture, the Notes, the Note Guarantees or the other Note Documents without the consent of any Holder of Notes: 

(1) to cure any ambiguity, defect or inconsistency; 
 (2) to
provide for uncertificated Notes in addition to or in place of certificated Notes;

Guarantor’s obligations to the Holders of the Notes and Note Guarantees by a successor to the Company or such Guarantor pursuant to Article 5 or Article 10 hereof;

hereunder of any Holder; 
 (5) to provide for the issuance of Additional Notes or PIK Interest Notes or to increase the outstanding principal amount of the
Notes, in each case in accordance with the limitations set forth in this Indenture as of the date hereof; 

  
 102 

 (6) to release or subordinate Liens on Collateral in accordance with the Note Documents; 

(7) to confirm and evidence the release, termination or discharge of any Lien with respect to or securing the Notes or the Note Guarantees when such release,
termination or discharge is provided for in accordance with this Indenture and the other Note Documents; 
 (8) to allow any Guarantor to execute a
supplemental indenture and/or a Note Guarantee with respect to the Notes or release the Note Guarantees pursuant to the terms of this Indenture; 
 (9) to
add any Collateral or to evidence the release of any Liens, in each case as provided in this Indenture or the other Note Documents, as applicable; 
 (10)
with respect to the Security Documents, as provided in the Intercreditor Agreement; 
 (11) to make, complete or confirm any grant of Collateral permitted
or required by this Indenture or any of the Security Documents establishing Parity Liens (including to secure Parity Lien Obligations permitted to be incurred and secured under this Indenture); 

(12) to evidence and provide for the acceptance under this Indenture of a successor Trustee; or 

(13) to modify Section 2.06 solely for the purpose of providing for the removal of the Private Placement Legend from any Note and to allow for the

In addition, without the consent of any Holder, the Intercreditor Agreement and the Collateral Trust Agreement may be amended in accordance
with their terms, including to add additional Indebtedness as Priority Lien Debt, Parity Lien Debt or Junior Lien Debt and add other parties (or any authorized agent thereof or trustee therefor) holding such Indebtedness thereto and to establish
that the Liens on any Collateral securing such Indebtedness shall rank equally with the Liens on such Collateral securing the other Priority Lien Debt, Parity Lien Debt or Junior Lien Debt, as applicable, then outstanding. 

Each Holder of Notes hereunder (x) consents to the amendment of any Note Document in the manner and for the purposes set forth in this
Section 9.01, (y) agrees that it will be bound by and will take no actions contrary to the provisions of any amendment to any Note Document pursuant to Section 9.01 and (z) authorizes and instructs the Trustee and the Collateral
Trustee (and the Trustee to direct the Collateral Trustee, if necessary) to enter into any amendment to any Note Document pursuant to this Section 9.01 on behalf of such Holder of Notes. 

Upon the request of the Company, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join
with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but
the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 

  
 103 

 Section 9.02 With Consent of Holders of Notes. 

Except as provided below in this Section 9.02, the Company, the Guarantors, the Trustee and the Collateral Trustee (if applicable with
respect to the Security Documents) may amend or supplement this Indenture (including, without limitation, Section 3.09, 4.12, 4.15, and 4.16 hereof), the Notes, the Note Guarantees and the Security Documents with the consent of the Holders of
at least a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes and the PIK Interest Notes, if any) voting as a single class (including, without limitation, consents obtained in
connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Section 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, the Notes, the Note Guarantees and the Security Documents 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 and PIK Interest 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 in the execution of such amended or supplemental
indenture and will direct the Collateral Trustee to execute any amendment or supplement to the Security Documents unless such amended or supplemental indenture or such Security Document amendment or supplement 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 and may but shall not be obligated to direct the Collateral
Trustee to enter into such amendment or supplement to the Security Documents. 
 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 send 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; 

  
 104 

 (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 Section 3.09, 4.12, 4.15 and 4.16 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 bring suit for the
enforcement of 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 Section 3.09, 4.12 or 4.15 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 the Note Documents; or 
 (9) make any change in the preceding amendment and waiver
provisions. 
 In addition, any amendment or supplement to, or waiver of, the provisions of this Indenture or any Note Document that has the
effect of releasing all or substantially all of the Collateral from the Liens securing the Notes will require the consent of the Holders of at least 66 2?3% in aggregate principal amount of the Notes then outstanding. 

Section 9.03 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 9.04 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. 

  
 105 

 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 9.05 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. 

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. 

  
 106 

 (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. 

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 this Indenture or a supplemental
indenture in substantially the form attached hereto as Exhibit E 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. 

  
 107 

 If an Officer whose signature is on this Indenture or a supplemental indenture no longer holds
that office at the time the Trustee authenticates the Note, 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 4.18 hereof, the Company will cause such Domestic Subsidiary to comply with the provisions of Section 4.18 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 reasonably satisfactory to the Trustee; or 
 (b) such transaction complies with
Section 4.12 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. 

Except as set forth in Article 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. 

  
 108 

 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 4.12 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 4.12 hereof, the Trustee will execute any documents reasonably requested by the Company or such Guarantor 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 4.12
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 4.12 hereof, the Trustee will execute any documents reasonably requested by the Company or such Guarantor 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. 

  
 109 

 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 (assuming the payment of interest as Cash Interest through such date); 

(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 Section 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 7.06 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. 

  
 110 

 Section 11.02 Application of Trust Money. 

Subject to the provisions of Section 8.06 hereof, all money or Government Securities deposited with the Trustee pursuant to
Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent)
as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the
extent required by law. 
 If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with

 (b) Each Holder of the Notes, by its acceptance thereof and of the Note Guarantees, consents and agrees to the
terms of the Intercreditor Agreement and the Security Documents (including, without limitation, the provisions providing for foreclosure and release of Collateral and amendments to the Security Documents) as the same may be in effect or may be
amended from time to time in accordance with their terms and authorizes and appoints the Trustee to enter into a Collateral Trust Joinder (as defined in the Collateral Trust Agreement) (such joinder, a “Collateral Trust Joinder”) to

appoint) MSSF, as the Collateral Trustee. Each Holder of the Notes further directs the Collateral Trustee (and authorizes the Trustee to direct the Collateral Trustee) to enter into the Security Documents (including any amendments thereto and any
security documents to secure additional Parity Lien Debt in accordance with the Collateral Trust Agreement, all as more particularly described in the Collateral Trust Agreement) and to perform its obligations and exercise its rights thereunder in

Holder of the Notes, by accepting the Notes and the Note Guarantees of the Guarantors (with respect to the Holders) and the benefits of the Note Documents, acknowledges that, as more fully set forth in the Security Documents, the Collateral as now
or hereafter constituted shall be held for the benefit of all the holders of Parity Lien Obligations, subject to the Intercreditor Agreement, the Collateral Trustee and the Trustee, and the Lien of this Indenture and the Security Documents is
subject to and qualified and limited in all respects by the Intercreditor Agreement, the Security Documents and actions that may be taken thereunder. 
 (c)
Notwithstanding any provision in this Indenture or any other Note Document to the contrary, in no event is any Building or Mobile Home included in the definition of “Mortgaged Properties” or the definition of “Collateral” and no

Section 13.02 Concerning the Trustee. 
 (a) The
Trustee shall not be obligated to take any action (or to direct the Collateral Trustee to take any action) under the Collateral Trust Agreement or any other Security Document without the written direction of the Holders in accordance with this
Indenture. 
 (b) Neither the Trustee nor any of its officers, directors, employees, attorneys or agents shall be responsible or liable (i) for the
legality, enforceability, effectiveness or sufficiency of the Security Documents, for the creation, perfection, priority, sufficiency, maintenance, renewal or protection of any Lien, or for any defect or deficiency as to any such matters, or
(ii) for any failure to demand, collect, foreclose or realize upon or otherwise enforce any of the Liens or 

  
 115 

 
Security Documents or any delay in doing so, or (iii) for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title, for
insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. 

(c) The rights, privileges, protections, immunities and benefits given to the Trustee under this Indenture, including, without limitation, its right to be
indemnified and compensated and all other rights, privileges, protections, immunities and benefits set forth in this Indenture are extended to the Trustee when acting under the Collateral Trust Agreement and the other Note Documents. 

(d) The Trustee will not be responsible for filing any financing or continuation statements or recording any documents or instruments at any time or times or
otherwise perfecting or maintaining the perfection of any Liens on the Collateral. 
 (e) Whenever an action under the Collateral Trust Agreement requires
an Act of Parity Lien Debtholders (as defined in the Collateral Trust Agreement), the Trustee, in its capacity as Parity Lien Representative, shall seek the direction of Holders of the Notes (if Holder consent or direction is required under this
Indenture). Subject to the next succeeding sentence, the Trustee shall deliver an affirmative vote in such Act of Parity Lien Debtholders in the entire aggregate outstanding principal amount of the Notes, if the minimum consent or directions of
Holders for such action required under this Indenture are met. If the requested action requires the consent or direction of each Holder of the Notes affected thereby, then the Trustee shall not deliver an affirmative vote in such Act of Parity Lien
Secured Debtholders unless it receives the consent of each Holder. 
 Section 13.03 Authorization of Actions to be Taken. 

(a) Subject to the provisions of Section 7.01 and Section 7.02 hereof and the Security Documents, the Trustee, upon the written direction of the
Holders holding a majority of the aggregate outstanding principal amount of the Notes shall direct, on behalf of the Holders, the Collateral Trustee to take all actions it deems necessary or appropriate in order to: 

(1) foreclose upon or otherwise enforce any or all of the Liens on the Collateral; 

(2) enforce any of the terms of the Security Documents to which the Collateral Trustee is a party; or 

(3) collect and receive payment of any and all Obligations. 

(b) At the Company’s sole cost and expense and subject to the Trustee and the Collateral Trustee having been indemnified by the Holders and/or the
Company, the Trustee is authorized and empowered (but is not obligated) to direct the Collateral Trustee to institute and maintain, such suits and proceedings as may be reasonably expedient to preserve or protect its interests and the interests of
the Holders of Notes in the Collateral, including the power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional
or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest hereunder or be prejudicial to the interests of Holders or the Trustee. 

  
 116 

 Section 13.04 Post-Issue Date Collateral Requirements. 

Notwithstanding anything to the contrary contained in this Indenture or the other Note Documents, the parties hereto acknowledge and agree
that the Company shall deliver, or cause one or more Guarantors to deliver, to the Collateral Trustee the following items within 30 days after the Issue Date: 

(a) fully executed counterparts of Mortgages (in sufficient counterparts for the prompt recordation in each jurisdiction in which the Mortgaged Property
subject to such Mortgage is located) and to the extent requested by the Collateral Trustee, corresponding UCC fixture filings or as-extracted collateral filings (or, if UCC fixture filings and as-extracted collateral filings are not available in the
applicable jurisdiction, equivalent filings as available in such jurisdiction), and any similar filings as shall be required by local law, in form and substance reasonably satisfactory to the Collateral Trustee, which Mortgages, UCC fixture filings
or as-extracted collateral filings (or, in the case of UCC fixture filings and as-extracted collateral filings, any other equivalent filings, as available in each applicable jurisdiction) or other similar filings shall cover each Mortgaged Property,
together with evidence reasonably satisfactory to the Collateral Trustee that such Mortgages, UCC fixture filings or as-extracted collateral filings (or, in the case of UCC fixture filings and as-extracted collateral filings, any other equivalent
filings, as available in each applicable jurisdiction) or similar filings have been delivered to the Persons responsible for recording or filing, as applicable, of such Mortgages, UCC fixture filings, as-extracted collateral filings, equivalent
filings or similar filings, as the case may be; 
 (b) title information and lien searches with respect to the Mortgaged Properties, as requested by
Collateral Trustee; and 
 (c) legal opinions addressed to the Collateral Trustee and the Trustee from (1) local counsel, covering, without limitation,
the enforceability of each Mortgage under the laws of the jurisdiction in which the Mortgaged Property subject to such Mortgage is located, the creation of valid mortgage Liens on such Mortgaged Property under the laws of the jurisdiction in which
the Mortgaged Property subject to such Mortgage is located and other matters customarily addressed in legal opinions of local counsel with respect to the Mortgages, and (2) outside counsel to the Company of national standing, covering, without
limitation, the due authorization, execution and delivery of the Mortgages with respect to Delaware and Texas laws, in each case, in form and substance substantially equivalent to the opinions previously delivered to the Collateral Trustee. 

The Company shall file a Current Report on Form 8-K with the SEC within the applicable time period for such a filing, containing customary detail on such
actions, upon completion of the deliveries referred to in this Section 13.04. 
 Section 13.05 Intercreditor Agreement. 

This Article 13 and the provisions of each other Security Document are subject to the terms, conditions and benefits set forth in the
Intercreditor Agreement. The Company and each Guarantor consents to, and agrees to be bound by, the terms of the Intercreditor Agreement, as 

  
 117 

 
the same may be in effect from time to time, and to perform its obligations thereunder in accordance with the terms thereof. Each Holder of Notes, by its acceptance of the Notes
(a) consents to the subordination of Liens provided for in the Intercreditor Agreement, (b) agrees that it will be bound by, and will take no actions contrary to, the provisions of the Intercreditor Agreement and (c) authorizes and
instructs the Collateral Trustee (and the Trustee to direct the Collateral Trustee) on behalf of each Holder of Notes to enter into the Intercreditor Agreement as Second Lien Collateral Trustee (as defined in the Intercreditor Agreement) on behalf
of such Holders of Notes as Second Lien Secured Parties (as defined in the Intercreditor Agreement). In addition, each Holder of Notes authorizes and instructs the Collateral Trustee to enter into any amendments or joinders to the Intercreditor
Agreement, without the consent of any Holder or the Trustee, to add additional Indebtedness as Priority Lien Debt, Parity Lien Debt or Junior Lien Debt and add other parties (or any authorized agent or trustee therefor) holding such Indebtedness
thereto and to establish that the Lien on any Collateral securing such Indebtedness ranks equally with the Liens on such Collateral securing the other Priority Lien Debt, Parity Lien Debt or Junior Lien Debt, as applicable, then
outstanding. The foregoing provisions are intended as an inducement to the lenders under the Credit Agreement to extend credit to the Company and certain of its Subsidiaries, and such lenders are intended third party beneficiaries of such
provisions and the provisions of the Intercreditor Agreement. 
 Section 13.06 Collateral Trust Agreement. 

This Article 13 and the provisions of each Security Document are subject to the terms, conditions and benefits set forth in the Collateral
Trust Agreement. The Company and each Guarantor consents to, and agrees to be bound by, the terms of the Collateral Trust Agreement, as the same may be in effect from time to time, and to perform its obligations thereunder in accordance with the
terms therewith. Each Holder of Notes, by its acceptance of the Notes (a) agrees that it will be bound by, and will take no actions contrary to, the provisions of the Collateral Trust Agreement and (b) authorizes and instructs the Trustee,
on behalf of each holder of Notes Obligations, to execute and deliver a Collateral Trust Joinder to the Collateral Trust Agreement (and to direct the Collateral Trustee to execute and deliver the Collateral Trust Agreement), which shall subject such
holders of Notes Obligations to the terms of the Collateral Trust Agreement and to perform its obligations thereunder as a Parity Lien Representative. 

Section 13.07 Release of Liens in Respect of Notes. 

The Collateral Trustee’s Parity Liens upon the Collateral will no longer secure the Notes outstanding under this Indenture or any other
Notes Obligations, and the right of the Holders to the benefits and proceeds of the Collateral Trustee’s Liens on the Collateral will terminate and be discharged: 

(a) in whole, upon satisfaction and discharge of this Indenture in accordance with Article 11 hereof; 

(b) in whole, upon a Legal Defeasance or Covenant Defeasance of the Notes in accordance with Article 8 hereof; 

  
 118 

 (c) in part, upon payment in full in cash and discharge of all Notes outstanding under this Indenture and all
other Notes Obligations that are outstanding, due and payable under this Indenture and the other Note Documents at the time the Notes are paid in full in cash and discharged (other than contingent indemnity obligations for which no claim has been
made); 
 (d) as to any Collateral of the Company or a Guarantor that is sold, transferred or otherwise disposed of by the Company or any Guarantor to a
Person that is not (either before or after such sale, transfer or disposition) the Company or a Restricted Subsidiary of the Company in a transaction or other circumstance that complies with Section 4.12 and is permitted by all of the other
Note Documents, at the time of such sale, transfer or other disposition or to the extent of the interest sold, transferred or otherwise disposed of; 
 (e)
in whole or in part, with the consent of the Holders of the requisite aggregate principal amount of Notes in accordance with Article 9 hereof; 
 (f) with
respect to the assets of any Guarantor, at the time that such Guarantor is released from its Note Guarantee in accordance with Section 10.05; or 
 (g)
if and to the extent required by Section 4.01 of the Intercreditor Agreement. 
 In addition, the Collateral Trustee’s Liens on the
Collateral will be released upon the terms and subject to the conditions set forth in Section 3.2 of the Collateral Trust Agreement. If the Priority Lien Obligations are repaid in full and the related commitments terminated thereunder without
being replaced, the Liens on the Collateral in favor of the Collateral Trustee for the benefit of itself, the Trustee and the Holders of the Notes and the other Parity Lien Obligations will not be released at such time, except to the extent the
Collateral or any portion thereof was disposed of in order to repay the Obligations under the Priority Lien Obligations secured by the Collateral in compliance with Section 4.12 hereof. 

Section 13.08 Additional Indebtedness. 

In connection with the incurrence by the Company or any Subsidiary thereof of any Priority Lien Obligations, Parity Lien Obligations or Junior
Lien Obligations permitted to be incurred pursuant to the terms hereof and of any other then outstanding Priority Lien Documents, Parity Lien Documents and Junior Lien Documents, Holders, by their acceptance of a Note, authorize and direct the
Trustee to execute and deliver (and to direct the Collateral Trustee to execute and deliver) any supplements, joinders or confirmations to the Intercreditor Agreement and Collateral Trust Agreement and any amendments, amendments and restatements,
restatements or waivers of or supplements to or other modifications to any Security Document (including but not limited to any Mortgages and UCC fixture filings), and to make or consent to any filings or take any other actions in connection
therewith, as may be reasonably deemed by the Company to be necessary or reasonably desirable for any Lien on the assets of the Company or any Subsidiary permitted to secure such Indebtedness to become a valid, perfected lien (with such priority as
may be designated by the Company, the relevant Guarantor or Subsidiary, to the extent such priority is permitted by the Note Documents) pursuant to the Security Document being so amended, amended and restated, restated, waived, supplemented or
otherwise modified or otherwise.

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

(1) INTEREST. W&T Offshore, Inc., a Texas corporation (the “Company”), promises to pay Cash Interest on the principal amount of
this Note at 9.00% per annum (the “Cash Interest 

  
 A-5 

 Rate”) from September 7, 20161 until maturity;
provided, however, that for any interest period ending on or prior to November 15, 20172, the Company may elect to pay all or any portion of interest in kind on the then
outstanding principal amount of this Note at a rate of 10.75% per annum (the “PIK Interest Rate”) by increasing the principal amount of the outstanding Notes or by issuing additional Notes (“PIK Interest
Notes”) in a principal amount equal to such interest (“PIK Interest”). The Company will pay interest semi-annually in arrears on May 15 and November 15 of each year, or if any such day is not a Business Day, on
the next succeeding Business Day (each, an “Interest Payment Date”). [The initial interest payment on November 15, 2016 will be made solely in PIK Interest at the PIK Interest
Rate.]3 On the May 15, 2018 Interest Payment Date, the Company shall be permitted to make only part of the interest payment in PIK Interest at the PIK Interest Rate and part of the interest
payment in Cash Interest at the Cash Interest Rate, provided, that PIK Interest to be paid on such Interest Payment Date shall accrue only for the period from November 15, 2017 to, but not including, March 7, 2018, and any remaining
interest for such period shall be payable solely in Cash Interest. Interest shall be payable entirely in Cash Interest for all Interest Payment Dates after May 15, 2018. Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face
hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be November 15, 20164. The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate that is
1% per annum in excess of the rate then in effect 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 periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

(2) METHOD OF PAYMENT. Except as provided in Section (1) of this Note, interest on the Notes shall be payable entirely in cash (“Cash
Interest”). The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the May 1 or November 1 next preceding the Interest Payment Date,
even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if
any, and Cash Interest at the office or agency of the Company maintained for such purpose within or without the City and State of New York, or, at the option of the Company, payment of Cash Interest may be made by check mailed to the Holders at
their addresses set forth in the register of Holders; provided that payment of Cash Interest by wire transfer of immediately available funds will be required with respect to principal, interest, and premium, if any, on, all Global Notes and
all other Notes the Holders of 
  

	1 	For Additional Notes, insert the appropriate date for such Additional Notes. 

	2 	For Initial Notes and any Additional Notes issued prior to the date which is 18 months following the Issue Date. 

	3 	For Initial Notes and any Additional Notes issued prior to November 15, 2016. 

	4 	 For Additional Notes, insert the appropriate Interest Payment Date for such Additional Notes.

  
 A-6 

 
which will have provided wire transfer instructions to the Company or the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. 
 In connection with the payment of PIK Interest in respect of the Notes, the Company
shall be entitled, without the consent of the Holders thereof (and without regard to any restrictions or limitations set forth in Section 4.09 of the Indenture), to issue PIK Interest Notes by (i) increasing the outstanding principal
amount of the then authenticated Global Notes or (ii) by issuing Definitive Notes under the Indenture on the same terms and conditions as the Initial Notes (in each case, a “PIK Payment”). 

Notwithstanding anything to the contrary, the payment of accrued interest in connection with any redemption or repurchase of the Notes as
described under Sections 3.07, 3.09, 4.12, 4.15 or 4.16 of the Indenture will be made solely in Cash Interest. If the Company elects to pay interest on the Notes as a combination of Cash Interest and as PIK Interest, Cash Interest and PIK Interest
shall be paid on the Notes to the Holders on a pro rata basis. 
 PIK Interest on the Notes will be payable (x) with respect to Notes
represented by one or more Global Notes registered in the name of, or held by, DTC or its nominee on the relevant record date, by increasing the principal amount of the outstanding Global Note by an amount equal to the amount of PIK Interest for the
applicable interest period (rounded up to the nearest whole dollar) as provided in writing by an Officer of the Company to the Trustee and, upon receipt of such written order of the Company, the Trustee shall increase the Global Notes by the amount
of PIK Interest (or authenticate new Global Notes if required by the applicable procedures of the Depositary) and (y) with respect to Definitive Notes, by issuing PIK Interest Notes in certificated form in an aggregate principal amount equal to
the amount of PIK Interest for the applicable period (rounded up to the nearest whole dollar), and the Trustee shall, at the request of the Company and upon receipt of an Authentication Order, authenticate and deliver such PIK Interest Notes in
certificated form for original issuance to the Holders on the relevant record date, as shown by the records of the register of Holders. Following an increase in the principal amount of the outstanding PIK Interest Notes as a result of a payment of
PIK Interest, the PIK Interest Notes shall bear interest on such increased principal amount from and after the date of such payment. Any PIK Interest Notes issued in certificated form shall be dated as of the applicable Interest Payment Date and
shall bear interest from and after such date. All PIK Interest Notes issued pursuant to a payment of PIK Interest shall be governed by, and subject to the terms, provisions and conditions of, the Indenture and shall have the same rights and benefits
as the Notes issued on the Issue Date. Any certificated PIK Interest Notes shall be issued with the description “PIK” on the face of such PIK Interest Note. 

(3) PAYING AGENT AND REGISTRAR. Initially, Wilmington Trust, National Association, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity. 

(4) INDENTURE AND SECURITY DOCUMENTS. The Company issued the Notes under an Indenture dated as of September 7, 2016 (the “Indenture”)
among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture. The Notes are 

  
 A-7 

 
subject to all such terms, and Holders are referred to the Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the
Indenture, the provisions of the Indenture shall govern and be controlling. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder. The Notes and the Guarantees are secured by Parity Liens on the
Collateral pursuant to the Security Documents. The rights of the Holders in the Collateral are subject to the terms of the Intercreditor Agreement and the Collateral Trust Agreement. 

(5) OPTIONAL REDEMPTION. 
 (a) Except as set forth in
subparagraphs (b), (c) and (d) of this Paragraph 5, the Company will not have the option to redeem the Notes prior to May 15, 2017. On or after May 15, 2017, the Company will have the option to redeem all or a part of the Notes
upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest on the Notes redeemed to the applicable redemption date, if redeemed
during the twelve-month period beginning on May 15 of the years indicated below, subject to the rights of Holders on the relevant record date to receive interest on the relevant Interest Payment Date: 

 

					
	 Year
	  	Percentage	 
	 2017
	  	 	104.500	% 
	 2018
	  	 	102.250	% 
	 2019 and thereafter
	  	 	100.000	% 

 Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on the Notes or portions
thereof called for redemption on the applicable redemption date. 
 (b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any
time prior to May 15, 2017, the Company may on any one or more occasions redeem up to 35% of the original aggregate principal amount of Notes issued under the Indenture with an amount of cash equal to the net cash proceeds of one or more Equity
Offerings at a redemption price equal to 109.000% of the aggregate principal amount thereof, plus accrued and unpaid interest to the redemption date; provided that at least 65% in aggregate principal amount of the Notes originally issued
under the Indenture remains outstanding immediately after the occurrence of such redemption and that such redemption occurs within 90 days of the date of the closing of the related Equity Offering. 

(c) At any time prior to May 15, 2017, the Company may also redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ notice,
at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but not including, the date of redemption, subject to the rights 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. 

  
 A-8 

 (d) In the event that Holders of not less than 90% of 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 4.15(d)) 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 to the Holders and the Trustee, given not more than 30 days following the purchase pursuant to Section 4.15, 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). 
 (6) MANDATORY
REDEMPTION. 
 The Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes. 

(7) REPURCHASE AT THE OPTION OF HOLDER. 
 (a) If there is a
Change of Control, the Company will be required to make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of each Holder’s Notes at a purchase
price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest thereon to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest
Payment Date (the “Change of Control Payment”). Within 10 days following any Change of Control, the Company will mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the
Indenture. 
 (b) If the Company or a Restricted Subsidiary of the Company consummates any Asset Sales, within five days of each date on which the aggregate
amount of Excess Proceeds exceeds $20.0 million, the Company will commence an offer to all Holders of Notes and all holders of other Indebtedness that is pari passu in right of payment with the Notes containing provisions similar to those set
forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets (an “Asset Sale Offer”) pursuant to Section 3.09 of the Indenture to purchase on a pro rata basis the maximum principal
amount of Notes (including any Additional Notes) and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the original principal amount thereof plus
accrued and unpaid interest thereon to the date of purchase, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes (including any Additional Notes) and other pari passu Indebtedness
tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company (or such Restricted Subsidiary) may use such deficiency for any purpose not otherwise prohibited by the 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). Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company prior to any related
purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes. 

  
 A-9 

 (c) If there is a Triggering Event, the Company will be required to make an offer (a “Triggering Event
Repurchase Offer”) to each Holder to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of each Holder’s Notes at a purchase price in cash equal to 100% of the aggregate principal amount thereof plus accrued
and unpaid interest thereon to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date. Within thirty days following any Triggering Event, the Company will mail
a notice to each Holder (with a copy to the Trustee) setting forth the procedures governing the Triggering Event Repurchase Offer as required by the Indenture. 

(8) NOTICE OF REDEMPTION. Notice of redemption will be sent at least 30 days but not more than 60 days before the redemption date 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 or discharge of the
Indenture. Notes in minimum denominations larger than $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. 

(9) DENOMINATIONS, TRANSFER, EXCHANGE. Subject to the issuance of PIK Interest Notes as described herein, the Notes are in registered form without
coupons in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof (or if a PIK Payment has been made, in minimum denominations of $1.00 and any integral multiple of $1.00 in excess thereof). The transfer of Notes may be
registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any
taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part.
Also, the Company need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.

(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 the
Indenture or the Notes, the Note Guarantees or the Security Documents may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes including Additional Notes, if any, voting as a single

outstanding principal amount of the Notes, to release or subordinate Liens on Collateral in accordance with the Note Documents, to confirm and evidence the release, termination or discharge of any Lien with respect to or securing the Notes or the

Parity Liens (including to secure Parity Lien Obligations permitted to be incurred and secured under the Indenture), to evidence and provide for the acceptance of a successor Trustee or to modify Section 2.06 of the Indenture solely for the
purpose of providing for the removal of the Private Placement Legend from any Note and to allow for the transfer of a Restricted Definitive Note or a beneficial interest in a Restricted Global Note to a Note that has an unrestricted CUSIP number, in
each case in accordance with applicable securities laws. 
 (12) DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30 days in
the payment when due of interest on the Notes; (ii) default in the payment when due of the principal of, or premium, if any, on, the Notes when the same becomes due and payable at maturity, upon redemption (including in connection with an offer

in the aggregate, having a fair market value in excess of $15.0 million, ceases to be an enforceable and perfected second-priority Lien, which failure is not cured within 45 days, and (x) except as permitted by the Indenture, any Note Guarantee

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, if any,) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate
principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under the Indenture except a
continuing Default or Event of Default in the payment of interest or premium, if any, on, or the principal of, the Notes. The Company is 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 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. 
 (15) AUTHENTICATION. This Note will not be valid until authenticated by the manual signature of the Trustee or an
authenticating agent. 
 (16) ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM

(17) CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes, and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any
notice of redemption, and reliance may be placed only on the other identification numbers placed thereon.

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 minimum denominations of $1,000 and integral multiples thereof (or if a PIK Payment has been made, in minimum denominations of $1.00 and any integral multiple of $1.00 in excess 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, redemptions and 

  
 41 

 
PIK Payments. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the
Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof. 

Section 2.02 Execution and Authentication. 

At least one Officer must sign the Notes for the Company by manual or facsimile signature. 

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be

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 or PIK Interest Notes as a result of a PIK Payment in accordance

 The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An

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.

as Depositary with respect to the Global Notes.

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 7.06 to compensate and indemnify the Trustee shall extend likewise to each Agent.

 Section 2.04 Paying Agent to Hold Money in Trust. 

The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit
of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or Cash 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. 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

FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING
THIS NOTE IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT, OR (C) IT IS AN INSTITUTIONAL “ACCREDITED INVESTOR” (AS DEFINED IN RULE 501(a)(1), (2), (3) OR (7) OF REGULATION D UNDER THE

TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE AND THE COMPANY SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM THAT
SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND “U.S.

Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any
time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the
principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the
beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased accordingly and an endorsement will be made on
such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. 
 (h) General Provisions Relating to
Transfers and Exchanges. 
 (1) To permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global
Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request. 
 (2) No
service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or
similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.14 and 9.04 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. 

  
 52 

 (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

 (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.

interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same
to determine substantial compliance as to form with the express requirements hereof. 
 Section 2.07 Replacement Notes. 

If any mutilated Note is surrendered to the Trustee or the Company and the Trustee and the Company receive evidence to their 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 to protect 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. 

  
 53 

 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 Company and the Trustee receives proof satisfactory to each of them 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. 
 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

  
 54 

 
destroy canceled Notes (subject to the record retention requirement of the Exchange Act and the Trustee’s customary procedures). 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 delivered at least 5 Business Days before such notice is to be
sent, the Trustee in the name and at the expense of the Company) will send or cause to be sent to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 

Section 2.13 PIK Interest. 
 Except
as set forth in the following sentence and in Section 1 of the Notes, interest on the Notes shall be payable entirely in Cash Interest at the Cash Interest Rate. For any interest period ending on or prior to the June 15, 2018 Interest
Payment Date, the Company may elect to pay all or any portion of interest in kind at the PIK Interest Rate on the then outstanding principal amount of the Notes (a “PIK Payment”) by increasing the principal amount of the outstanding
Notes or by issuing additional Notes (each, a “PIK Interest Note”) in a principal amount equal to such interest (“PIK Interest”), provided, that the December 15, 2016 interest payment shall be made entirely in
PIK Interest at the PIK Interest Rate. On the December 15, 2018 Interest Payment Date, the Company shall be permitted to make only part of the interest payment in PIK Interest at the PIK Interest Rate and part of the interest payment in Cash
Interest at the Cash Interest Rate, provided, that PIK Interest to be paid on such Interest Payment Date shall accrue only for the period from June 15, 2018 to, but not including, September 7, 2018, and any remaining interest for
such period shall be payable solely in Cash Interest. 
 Notwithstanding anything to the contrary, the payment of accrued interest in
connection with any redemption or repurchase of the Notes as described under Section 3.07, 4.10 or 4.14 hereof will be made solely in Cash Interest. If the Company elects to pay interest on the Notes as a combination Cash Interest and PIK
Interest, such Cash Interest and PIK Interest shall be paid on the Notes on a pro rata basis. In the event that the Company shall elect to pay PIK Interest for any interest period, then the Company shall deliver a notice to the Trustee and the
Holders not less than five Business Days prior to the commencement of the relevant interest period, which notice shall state the total amount of interest to be paid on such Interest Payment Date and the total amount of PIK Interest. 

  
 55 

 Unless otherwise agreed between the Company and the Trustee, with respect to the issuance of any
PIK Interest Notes, the Company shall deliver to the Trustee no later than two Business Days prior to the applicable Interest Payment Date, (i) if such PIK Interest Notes are Definitive Notes, the required amount of new Definitive Notes
(rounded up to the nearest whole dollar) and an Authentication Order to authenticate and deliver such PIK Interest Notes on the relevant Interest Payment Date or (ii) if such PIK Interest Notes are Global Notes, by delivering a written order
from an Officer of the Company to the Trustee to increase the principal amount of the outstanding Global Note by an amount equal to the amount of PIK Interest for the applicable interest period (rounded up to the nearest whole dollar). 

Any PIK Interest Note shall, after being executed and, if applicable, authenticated pursuant to Section 2.02 hereof, be (i) if such
PIK Interest Notes are Definitive Notes, mailed to the Person entitled thereto as shown on the register for the Definitive Notes as of the relevant Record Date or (ii) if such PIK Interest Notes are Global Notes, deposited into the account
specified by the Holder or Holders thereof as of the relevant record date. 
 Notwithstanding the foregoing, in connection with any PIK
Payment on Notes that are Global Notes, the Company may, if requested in writing by any Holder or if required by the procedures of the Depositary, in lieu of increasing the principal amount of such Global Notes, issue the required amount of the PIK
Payment in the form of a new Global Note (rounded up to the nearest whole dollar) upon delivery to the Trustee of an Authentication Order to authenticate and deliver such new Global Note on the relevant Interest Payment Date. 

Any PIK Payment shall be made in such form and on terms as specified in this Section 2.13, and the Company shall and the Trustee and
Paying Agent may take additional steps as necessary to effect such PIK Payment.

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

 (5) that Notes
called for redemption must be surrendered to the Paying Agent to collect the redemption price; 
 (6) that, unless the Company defaults in making such
redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date; 
 (7) the paragraph in Section 3.07 of
this Indenture pursuant to which the Notes called for redemption are being redeemed; 

  
 57 

 (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 a copy of the notice of
redemption that sets 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 sent 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 pursuant to 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 (which amount, for the avoidance of doubt, shall be deposited in cash) 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 (which amount, for the avoidance of doubt, shall be deposited in cash). If any Note called for redemption or tendered for
purchase is not so paid upon surrender for redemption or purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or tendered for purchase date until
such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 

Section 3.06 Notes Redeemed or Purchased in Part. 

Upon surrender of a Note that is redeemed or purchased in part, the Company will issue and, upon receipt of an Authentication Order, the
Trustee will authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

issued under this Indenture at a redemption price of 108.500% of the principal amount thereof, plus accrued and unpaid interest to, but not including the redemption date (subject to the right of Holders on the relevant record date to receive
interest due on an Interest Payment Date that is not on or prior to the redemption date), with an amount of cash not greater than the net cash proceeds of one or more Equity Offerings; provided that: 

(1) at least 65% in aggregate principal amount of Notes originally issued under this Indenture remains outstanding immediately after the occurrence of such

prior to June 15, 2018. 
 (c) On or after June 15, 2018, the Company may redeem all or a part of the Notes upon not less than 30 nor more than 60
days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest on the Notes redeemed to, but not including, the applicable redemption date, if redeemed during the

more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but not including, the date of redemption, subject to the
rights 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. 
 (e) In the
event that Holders of not less than 90% of 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 to the Holders and the Trustee, 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 

  
 59 

 
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 Section 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 in right of payment 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 based on the outstanding amount of the Notes and such other Indebtedness that is pari passu with the Notes, 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. 

For the avoidance of doubt, each Asset Sale Offer shall be made to the Holders and to any applicable Other Offer Parties pursuant to
Section 4.10 and the aggregate amount of the Notes subject to any Asset Sale Offer that is also made to Other Offer Parties shall be an amount of Excess Proceeds that is proportionate to the then aggregate outstanding principal amount of the
Notes relative to the then outstanding principal amount of relevant Indebtedness of the Other Offer Parties. In addition, if the offer requirements or mechanics applicable to such other Indebtedness are not consistent with the procedures set forth
in this Section 3.09 for an Asset Sale Offer, the Company may change the procedures for such Asset Sale Offer from those set forth herein provided that (x) no change may be made with respect to the amount of Notes subject to the Asset Sale
Offer and (y) such procedures shall be clearly set out in the relevant Asset Sale Offer notice. 
 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. 

  
 60 

 Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail (or
electronically in the case of Global Notes), 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; 
 (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 and 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 the Company or the trustee or agent for such other pari passu Indebtedness will select such 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 or $1.00 or an integral multiple thereof in the case of any PIK Interest Notes, 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). 

  
 61 

 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 Section 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 Cash 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 due. Any PIK Payment shall be considered paid on the date it is due (a) if PIK Interest Notes
(including PIK Interest Notes that are Global Notes) have been issued therefor, such PIK Interest Notes have been executed by the Company and authenticated by the Trustee on or prior to the date the payment is due in accordance with the terms of
this Indenture and (b) if the PIK Payment is made by increasing the principal amount of Global Notes then authenticated, the Company has delivered the written request required by Section 2.13 and the Trustee has increased the principal
amount of Global Notes then authenticated by the relevant amount on or prior to the date the payment is due. 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 made. 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 at the Corporate Trust Office of the Trustee; provided that the Corporate Trust Office of the Trustee shall not be an office or agency of the Company for the purpose of service of legal
process against the Company or any Guarantor. 
 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, notices and demands may be made 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; provided that the Corporate Trust Office of the Trustee shall not be an office or agency of the Company for the purpose of service of legal process against the Company or any
Guarantor.

will furnish to the Holders of Notes and the Trustee, 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

 (c) 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 above 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

required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 
 (f) 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. The Trustee shall have no responsibility to determine whether such filing has occurred or if such
reports are publicly available. 
 (g) 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 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

 (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

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

no Default has occurred and is continuing or would be caused 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

(a) in the case of a Change of Control, the Company has first complied with and fully satisfied its obligations under Section 4.14 (including without
limitation the repurchase of all Notes validly tendered for payment in connection therewith); or 
 (b) in the case of an Asset Sale, the Company has
complied with and fully satisfied its obligations in accordance with Section 4.10 (including without limitation the repurchase of all Notes validly tendered for payment in connection therewith); 

(8) the repurchase, redemption or other acquisition or retirement for value of Capital Stock of the Company representing fractional shares of such Capital
Stock in connection with a merger, consolidation or other combination involving the Company or any other transaction permitted by this Indenture;

 (9) Restricted Payments of the type referred to in clauses (1) or (2) of the first paragraph of this

(10) other Restricted Payments in an aggregate amount not to exceed $200.0 million since the Prior Issue Date; and 

(11) the declaration and payment of regularly scheduled or accrued dividends to holders of any class or series of Disqualified Stock of the Company or any

(c) The amount of all Restricted Payments (other than cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair Market Value of any assets or securities that are 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. 
 Section 4.08
Dividend and Other Payment Restrictions Affecting Subsidiaries. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 

(1) pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries, or pay any indebtedness owed to
the Company or any of its Restricted Subsidiaries; 
 (2) make loans or advances to the Company or any of its Restricted Subsidiaries; or 

(3) sell, lease or transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries.

by reason of: 
 (1) the Second Lien Notes Indenture, the Second Lien Notes, the Second Lien Note Guarantees and agreements governing Existing Indebtedness
and Credit Facilities as in effect on the Issue Date and any amendments, restatements, modifications, renewals, supplements, increases, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements,
modifications, renewals, supplements, increases, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment encumbrances or restrictions than those contained in
those agreements on the Issue Date; 
 (2) this Indenture, the Notes, the Note Guarantees and the other Note Documents; 

(3) applicable law, rule, regulation, order, approval, permit or similar restriction; 

(4) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time
of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in 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;

Capital Lease Obligations and mortgage financings that impose restrictions on the property purchased or leased of the nature described in clause (3) of Section 4.08(a) hereof;

Stock or assets of a Restricted Subsidiary that restricts distributions by the applicable Restricted Subsidiary pending the sale or other disposition; 

(8) Liens permitted to be incurred under the provisions of Section 4.12 hereof that limit the right of the debtor to dispose of the assets subject to
such Liens; 
 (9) provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale agreements,
sale-leaseback agreements, stock sale agreements and other similar agreements entered into (a) in the ordinary course of business consistent with past practice or (b) with the approval of the Company’s Board of Directors, which
limitations are applicable only to the assets or property that are the subject of such agreements; 
 (10) other Indebtedness of the Company or any of its
Restricted Subsidiaries permitted to be incurred pursuant to an agreement entered into subsequent to the Issue Date in accordance with Section 4.09; provided that the provisions of such agreement relating to such dividend and other
payment encumbrances or restrictions taken as a whole are not materially more restrictive, as determined by the Board of Directors or the Company in good faith, than those provisions 

  
 70 

 
contained in the agreements governing Existing Indebtedness, the Existing Revolving Credit Agreement, the Existing Term Loan Agreement, the 1.5 Lien Term Loan Agreement and the Second Lien Notes
Indenture, in each case as in effect on the Issue Date; 
 (11) the issuance of preferred stock by a Restricted Subsidiary or the payment of dividends
thereon in accordance with Section 4.09 and the terms thereof; provided that issuance of such preferred stock was made in accordance and the terms of such preferred stock do not expressly restrict the ability of a Restricted Subsidiary
to pay dividends or make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such preferred stock prior to paying any dividends or making any other distributions on such other Capital

Section 4.09 Incurrence of Indebtedness and Issuance of 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: 

  
 71 

 (i) $800.0 million; and 

(ii) 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; 
 (3) the incurrence by the Company and the Guarantors of
Indebtedness represented by (a) the Notes and the related Note Guarantees to be issued on the Issue Date (including any increase in principal amount as a result of a PIK Payment and any PIK Interest Notes in respect thereof) and (b) the
Second Lien Notes and the related guarantees thereof issued on the Issue Date (including any increase in principal amount and any PIK interest notes in respect thereof, in each case as a result of a PIK payment); 

(4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or
purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the business of the Company or
any of its Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), not to
exceed $50.0 million at any time outstanding; 
 (5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing
Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under
Section 4.09(a) hereof or clauses (2), (3), (4) or (11) of this Section 4.09(b) or this clause (5); 
 (6) the incurrence by the Company
or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that: 

(A) if the Company or any Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness must be expressly
subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of the Company, or the Note Guarantee, in the case of a Guarantor; and 

(B) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a
Restricted Subsidiary of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary of the Company will be deemed, in each case, to constitute an incurrence of
such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); 

  
 72 

 (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 or any of its Restricted Subsidiaries of obligations relating to net gas balancing positions arising in the ordinary course
of business and consistent with past practice; 
 (10) the Guarantee by the Company or any of the Guarantors of Indebtedness of the Company or a Restricted
Subsidiary of the Company that was permitted to be incurred by another provision of this Section 4.09; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the Guarantee shall be
subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed; 
 (11) Permitted Acquisition Indebtedness; 

(12) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other financial institution of
a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days; 

(13) Indebtedness consisting of the financing of insurance premiums in customary amounts consistent with the operations and business of the Company and its
Restricted Subsidiaries; 
 (14) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from agreements of the Company
or any of its Restricted Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any business, assets or Capital Stock of a Subsidiary,
provided that the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds actually received by the Company and its Restricted Subsidiaries in connection with such disposition; 

  
 73 

 (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. 
 (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. 

  
 74 

 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. 

(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) (A) if the Asset Sale is a Collateral Disposition, to repay, prepay, redeem or repurchase Priority Lien Debt, Second Lien Debt and other
outstanding Second Lien Obligations, the Notes and Third Lien Debt and other outstanding Third Lien Obligations; provided that with respect to Third Lien Debt, such repayment, prepayment, redemption or repurchase must be made either by a pro rata
redemption or repayment of outstanding Third Lien Debt or by an offer to purchase on a pro rata basis made to all holders of Third Lien Obligations under the procedures set forth in Section 3.09 or (B) if such Asset Sale is not a
Collateral Disposition, to repay, prepay, redeem or 

  
 75 

 
repurchase Indebtedness of the Company or another Restricted Subsidiary that is not subordinated in right of payment to the Notes (but, in each case, excluding intercompany Indebtedness of the
Company or any Restricted Subsidiary or any of its Affiliates); 
 (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 (i) with respect to Excess Proceeds from any Asset Sale that is a
Collateral Disposition, all holders of Priority Lien Obligations, Second Lien Obligations and other Third Lien Obligations; provided that to the extent that the terms of the Priority Lien Obligations or the Second Lien Obligations require
that such Priority Lien Obligations or Second Lien Obligations, as applicable, be repaid with the Net Proceeds of Asset Sales prior to repayment of other Indebtedness (including the Notes), the Company and its Restricted Subsidiaries shall be
entitled to repay such other Priority Lien Obligations and/or Second Lien Obligations prior to repaying the Obligations under the Notes, or (ii) with respect to other Excess Proceeds, all holders of other Indebtedness that is pari passu
in right of payment with the Notes (with a copy to the Trustee) containing provisions similar to those set forth in this Indenture (such applicable holders of any Third Lien Obligations or other applicable pari passu Indebtedness, the
“Other Offer Parties”) with respect to offers to purchase, repay or redeem with the proceeds of sales of assets in accordance with Section 3.09 hereof to purchase or repay on a pro rata basis the maximum principal amount of
Notes and such other pari passu Indebtedness that may be purchased or repaid 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 or repayment, 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

  
 76 

 
Section 3.09 hereof or this Section 4.10, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under
Section 3.09 hereof or this Section 4.10 by virtue of such compliance. 
 Section 4.11 Transactions with Affiliates. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any
of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each
an “Affiliate Transaction”), unless: 
 (1) the Affiliate Transaction is on terms that are no less favorable to the Company or the relevant
Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and 

(2) the Company delivers to the Trustee: 
 (A) with respect to
any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $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 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; 

  
 77 

 (5) any issuance of Equity Interests (other than Disqualified Stock) of the Company to, or receipt by the Company
of a capital contribution from, Affiliates (or a Person that becomes an Affiliate) of the Company; 
 (6) Restricted Payments that do not violate
Section 4.07 hereof; 
 (7) transactions between the Company or any Restricted Subsidiaries and any Person, a director of which is also a director of
the Company or any direct or indirect parent company of the Company and such director is the sole cause for such Person to be deemed an Affiliate of the Company or any Restricted Subsidiaries; provided, however, that such director
abstains from voting as director of the Company or such direct or indirect parent company, as the case may be, on any matter involving such other Person; 

(8) loans or advances to employees in the ordinary course of business or consistent with past practice not to exceed $5.0 million in the aggregate at any one
time outstanding; 
 (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 exchange offer 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 Indebtedness of the Company or any Guarantor. 

  
 78 

 Notwithstanding anything to the contrary contained in this Indenture, for so long as the Existing Senior
Unsecured Notes are outstanding, no Lien shall constitute a Permitted Lien under this Indenture which would not also be a “Permitted Lien” under the terms of the indenture governing the Existing Senior Unsecured Notes. 

Section 4.13 Corporate Existence. 

Subject to Article 5 hereof, so long as any of the Notes shall remain outstanding, the Company will at all times do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate existence. 
 Section 4.14 Offer to Repurchase Upon Change of
Control. 
 (a) Upon the occurrence of a Change of Control, each Holder of the Notes will have the right to require the Company to make an offer (a
“Change of Control Offer”) to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes
repurchased plus accrued and unpaid interest, if any, on the Notes repurchased to the date of purchase, subject to the rights of Holders on an record date to receive interest due on the relevant Interest Payment Date (the “Change of Control
Payment”). Within thirty days following any Change of Control, the Company will send a notice to each Holder (with a copy to the Trustee) 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 repurchased 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 

  
 79 

 (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. 

(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 send 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 (or $1.00 or an integral multiple thereof in the case of any PIK Interest Notes). 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. 

  
 80 

 (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 canceled, 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 and Collateral. 

(a) If, after the Issue Date, any Domestic Subsidiary (other than an Excluded 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 (i) become a Guarantor by executing and delivering a supplemental indenture in
the form attached hereto as Exhibit E and (ii) execute and deliver to the Collateral Trustee and the Trustee an amendment, supplement or other instrument in respect of the other Security Documents in form reasonably satisfactory to the
Collateral Trustee necessary to cause such Domestic Subsidiary to become a grantor thereunder and take all action required thereunder to perfect the Liens created thereunder, as well as to execute and deliver to the Collateral Trustee and the
Trustee joinders to the Intercreditor Agreement and the Collateral Trust Agreement, in each case within 180 days of the date on which it guaranteed such Indebtedness. 

(b) The Company and each of the Guarantors shall do or cause to be done all acts and things that may be required, or that the Collateral Trustee from time to
time may reasonably request, to assure and confirm that the Collateral Trustee holds, for the benefit of the holders of Third Lien Obligations, duly created and enforceable and perfected Liens upon the Collateral (including any acquired Property or
other Property required by any Third Lien Document to become, Collateral after the Issue Date), in each case, as contemplated by, and with the Lien priority required under, the Third Lien Documents, and in connection with any merger, consolidation
or sale of assets of the Company or any Guarantor, the property and assets of the Person which is consolidated or merged with or into the Company or any Guarantor, to the extent that they are property or assets of the types which would constitute
Collateral under the Security Documents, shall be treated as after-acquired property and the Company or such Guarantor shall take such action as may be reasonably necessary to cause such property and assets to be made subject to the Third Liens, in
the manner and to the extent required under the Third Lien Documents. 
 (c) Upon the reasonable request of the Collateral Trustee or any Third Lien
Representative at any time and from time to time, in each case at the direction of the holders of Third Lien Obligations in accordance with the terms of the applicable Third Lien Documents, the Company and each of the Guarantors shall promptly
execute, acknowledge and deliver such Security Documents, instruments, certificates, financing statements, notices and other documents, and take such other actions as shall be reasonably required, or that the Collateral Trustee may reasonably
request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred, in each case as contemplated by the Third Lien Documents for the benefit of the holders of Third Lien Obligations; provided, that no such
Security Document, instrument or other document shall be 

  
 81 

 
materially more burdensome upon the Company and the Guarantors than the Second Lien Documents executed and delivered (or required to be executed and delivered promptly after the date of this
Indenture) by the Company and the Guarantors in connection with the transactions contemplated by the Existing Term Loan Agreement. 
 (d) In addition to the
Collateral, from and after the Issue Date, if the Company or any Guarantor acquires any Property that constitutes collateral for the Priority Lien Debt or Second Lien Debt, if and to the extent that any Priority Lien Document or Second Lien
Document, as applicable, requires any supplemental security document for such collateral or other actions to achieve a perfected Lien on such collateral, the Company shall, or shall cause the applicable Guarantor to, promptly (but not in any event
no later than the date that is 20 Business Days after which such supplemental security documents are executed and delivered (or other action taken) under such Priority Lien Documents or Second Lien Documents, as applicable), to the extent
permitted by applicable law, execute and deliver to the Collateral Trustee appropriate Security Documents (or amendments thereto) in such form as shall be necessary to grant the Collateral Trustee a valid and enforceable perfected Lien on such
Collateral or take such other actions in favor of the Collateral Trustee as shall be reasonably necessary to grant a valid and enforceable perfected Lien on such Collateral to the Collateral Trustee, for the benefit of Holders of the Notes and the
holders of any other Third Lien Obligations, subject to the terms of this Indenture, the Intercreditor Agreement and the other Note Documents. Additionally, subject to this Indenture, the Intercreditor Agreement and the other Note Documents, if the
Company or any Guarantor creates any additional Lien upon any Property that would constitute Collateral, or takes any additional actions to perfect any existing Lien on Collateral, in each case for the benefit of the holders of the Priority Lien
Debt or the holders of Second Lien Debt, after the Issue Date, the Company or such Guarantor, as applicable, must, to the extent permitted by applicable law, within 20 Business Days after such Lien is granted or other action taken, grant a
valid and enforceable perfected Lien upon such property or asset, or take such additional perfection actions, as applicable, and obtain all related deliverables as those delivered to the Priority Lien Representative or Second Lien Representative, as
applicable, in each case as security for the Obligations. Notwithstanding the foregoing, to the extent that any Lien on any Collateral is perfected by the possession or control of such Collateral or of any account in which such Collateral is held,
and if such Collateral or any such account is in fact in the possession or under the control of the Priority Lien Representative or Second Lien Representative, or of agents or bailees of the Priority Lien Representative or Second Lien
Representative, as applicable, the perfection actions and related deliverables described in this Section 4.15(d) shall not be required. 
 (e) The
Company will deliver to the Collateral Trustee semi-annually on or before March 1 and September 1 in each calendar year, beginning March 1, 2017, an Officers’ Certificate certifying that, as of the date of such certificate, the
Collateral includes Oil and Gas Properties that include not less than 80% (or such greater amount as may be required by the Existing Revolving Credit Agreement in effect at such time) of the total discounted present value of Proved Reserves
attributable the Oil and Gas Properties of the Company and its Restricted Subsidiaries, as evaluated in the most recent Reserve Report, after giving effect to exploration and production activities, acquisitions, dispositions and production since the
date of such Reserve Report (the “Minimum Mortgage Requirement”), together with (i) such executed Mortgages or amendments or supplements to prior Mortgages naming the Collateral Trustee, as mortgagee or beneficiary, as

  
 82 

 
may be necessary to cause the Minimum Mortgage Requirement to be satisfied, (ii) reasonably satisfactory evidence of the completion of all recordings and filings of such Mortgages,
amendments or supplements in the proper recorders’ offices or appropriate public records (and payment of any taxes or fees in connection therewith) and (iii) local counsel opinion or opinions (each, subject to customary assumptions and
qualifications) to the effect that the Collateral Trustee has a valid and perfected Lien with respect to the real property that is subject to the applicable Mortgage; provided that, (x) to the extent corresponding mortgages securing the
Priority Lien Obligations or Second Lien Obligations are being delivered and (y) Mortgages have previously been recorded in the public records of the county or counties applicable to such additional Mortgages or amendments or supplements to
prior Mortgages, no such opinion shall be required unless a corresponding opinion will be delivered to the Priority Lien Agent or Second Lien Representative. The certificate referred to in this Section 4.15(e) shall include a schedule tied to
the Reserve Report identifying those properties treated in the Reserve Report as Collateral from those properties treated in the Reserve Report which are not Collateral. 

(f) Notwithstanding anything herein or in the Note Documents to the contrary, neither the Company nor any Guarantor will be required to grant a security
interest in, and the Collateral shall not include, any Excluded Asset. 
 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. 

  
 83 

 Section 4.17 Insurance. 
  

	(a)	The Company and the Guarantors shall: 

  

	 	(1)	keep their properties insured at all times by financially sound and reputable insurers; 

  

	 	(2)	maintain such other insurance, to such extent and against such risks (and with such deductibles, retentions and exclusions), including fire and other risks insured against by extended coverage and coverage for acts of
terrorism, as is customary with companies in the same or similar businesses operating in the same or similar locations, including public liability insurance against claims for personal injury or death or property damage occurring upon, in, about or
in connection with the use of any properties owned, occupied or controlled by them; and 

  

	 	(3)	maintain such other insurance as may be required by law. 

  

	(b)	Upon the request of the Collateral Trustee at the direction of the holders of Third Lien Obligations in accordance with the terms of the applicable Third Lien Documents, the Company and the Guarantors will furnish to
the Collateral Trustee information as to their property and liability insurance carriers. Within 60 days of the Issue Date, the Company will use its reasonable efforts to cause the holders of Third Lien Obligations, as a class, to be named as
additional insureds on all general liability insurance policies of the Company and the Guarantors, and the Collateral Trustee to be named as loss payee on all property and casualty insurance policies of the Company and the Guarantors that insure the
Collateral. 

 Section 4.18 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). 

  
 84 

 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. 

The Trustee shall have no duty to monitor whether or not the Notes have been assigned an Investment Grade Rating, nor any duty to notify the
Holders of any of the foregoing.

Person (whether or not the Company is the surviving corporation); or (ii) sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties and assets, in one or more related transactions, to another
Person, unless: 
 (1) either: 
 (A) the Company is the
surviving corporation; or

assignment, transfer, conveyance or other disposition has been made assumes all the obligations of the Company under the Notes, this Indenture and the other Note Documents and pursuant to agreements in form 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 in form reasonably satisfactory to the Trustee. 

(3) immediately after such transaction or transactions, no Default or Event of Default exists; 

(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,

period, (a) be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.09(a) hereof or (b) have a Fixed Charge Coverage Ratio not less than the Fixed Charge

other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the

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

 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;

 (3) failure by the Company or any of its Restricted Subsidiaries to comply with the provisions of
Section 3.09, 4.10, 4.14 or 5.01 hereof;

the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class to comply with any of the other agreements in this Indenture; 

(5) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for
money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the Issue Date,
if that default: 
 (A) is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness prior to the expiration of the
grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or 
 (B) results in the acceleration of such
Indebtedness prior to its express maturity, 
 and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any
other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $20.0 million or more; provided that if any such default is cured or waived or any such acceleration rescinded,
or such Indebtedness is repaid, within a period of 15 Business Days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequential
acceleration of the Notes shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree; 
 (6) failure by the
Company or any of its Restricted Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $20.0 million (net of any amount with respect to which a reputable and solvent insurance company has
acknowledged liability in writing), which judgments are not paid, discharged, stayed or fully bonded for a period of 60 days (or, if later, the date when payment is due pursuant to such judgment); 

(7) the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken

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

(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

(9) the occurrence of any of the following: 
 (A) except as
permitted by the Note Documents, any Security Document establishing the Third Liens ceases for any reason to be enforceable; provided that it will not be an Event of Default under this clause (9)(A) if the sole result of the failure of one or
more Security Documents to be fully enforceable is that any Third Lien purported to be granted under such Security Documents on Collateral, individually or in the aggregate, having a fair market value of not more than $15.0 million, ceases to be
enforceable; provided further that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 45 days after any officer of the Company or any Restricted Subsidiary becomes aware of such failure, which failure
has not been cured during such time period; 
 (B) except as permitted by the Note Documents, any Third Lien purported to be granted under any Security
Document on Collateral, individually or in the aggregate, having a fair market value in excess of $15.0 million, ceases to be an enforceable and perfected third-priority Lien, subject only to Permitted Liens and the terms of the Intercreditor
Agreement; provided that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 45 days after any officer of the Company or any Restricted Subsidiary becomes aware of such failure, which failure has not
been cured during such time period; 
 (C) the Company or any Guarantor, or any Person acting on behalf of any of them, denies or disaffirms, in writing,
any obligation of the Company or any Guarantor set forth in or arising under any Note Document establishing Third Liens; and

 88 

 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 

  
 89 

 
may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability. 
 Section 6.06 Limitation on Suits. 

A Holder may pursue a remedy with respect to this Indenture or the Notes only if: 

(1) such Holder gives to the Trustee written notice that an Event of Default is continuing; 

(2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy; 

(3) such Holder or Holders offer and, if requested, provide to the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss,
liability or expense; 
 (4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of security or
indemnity; and 
 (5) during such 60-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a
direction inconsistent with such request. 
 A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a
Note or to obtain a preference or priority over another Holder of a Note. 
 Section 6.07 Rights of Holders of Notes to Receive Payment. 

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to bring suit for the enforcement of payment of
principal, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), shall not be impaired or affected without the consent of such Holder. 

Section 6.08 Collection Suit by Trustee. 

If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover
judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium, if any, and interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest
and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

Section 6.09 Trustee May File Proofs of Claim. 

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the

  
 90 

 
Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or
deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 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 7.06 hereof out of the estate in any such proceeding, shall be denied
for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in
liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization,
arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 6.10 Priorities. 
 If the
Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

 The Trustee may fix a record date and payment date for

 ARTICLE 7 

TRUSTEE 
 Section 7.01 Duties of
Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 

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

  
 92 

 Section 7.02 Rights of Trustee. 

(a) The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee
need not investigate any fact or matter stated in the document. 
 (b) Before the Trustee acts or refrains from acting, it may require an Officers’
Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel and the
written advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. 

(c) The Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any agent appointed with due care.

 (d) The Trustee will not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or
powers conferred upon it by this Indenture. 
 (e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from
the Company will be sufficient if signed by an Officer of the Company. 
 (f) The Trustee will be under no obligation to exercise any of the rights or
powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to the Trustee against the losses, liabilities and expenses that might be
incurred by it in compliance with such request or direction. 
 (g) In no event shall the Trustee be responsible or liable for special, indirect, punitive
or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 

(h) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder (including, without limitation, as Collateral Trustee), and each Agent. 

(i) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder. 

(j) The Trustee shall not be bound to make any investigation into (i) the performance of or compliance with any of the covenants or agreements set forth
herein, (ii) the occurrence of any default, or the validity, enforceability, effectiveness or genuineness of this Indenture or any other agreement, instrument or document. 

  
 93 

 (k) The Trustee shall not be responsible or liable for any failure or delay in the performance of its obligations
under this Indenture arising out of or caused, directly or indirectly, by circumstances beyond its reasonable control, including, without limitation, acts of God; earthquakes; fire; flood; terrorism; wars and other military disturbances; sabotage;
epidemics; riots; interruptions; loss or malfunction of utilities, computer (hardware or software) or communication services; accidents; labor disputes; and acts of civil or military authorities and governmental action. 

(l) The permissive rights of the Trustee under this Indenture shall not be construed as duties. 

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 Section 7.09 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 actually known to a Responsible Officer of the Trustee, the Trustee
will send to Holders of Notes a notice of the Default or Event of Default within 90 days after it is actually known to the Trustee. 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 the Trustee in good faith determines that withholding the notice is in the interests of the Holders of the Notes. 

Section 7.06 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. 

  
 94 

 (b) The Company and the Guarantors will jointly and severally 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 7.06) 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 7.06 will survive the satisfaction and discharge of this Indenture or the
resignation or removal of the Trustee. 
 (d) To secure the Company’s and the Guarantors’ payment obligations in this Section 7.06, 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 6.01(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. 

Section 7.07 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 7.07. 

(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 7.09 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. 

  
 95 

 (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 7.09 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 7.06 hereof. Notwithstanding replacement of the Trustee pursuant to this Article 7, the Company’s obligations under Section 7.06 hereof will
continue for the benefit of the retiring Trustee. 
 Section 7.08 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. 
 Section 7.09 Eligibility; Disqualification.

 There will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of
America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $100.0
million as set forth in its most recent published annual report of condition. 
 This Indenture will always have a Trustee who satisfies the
requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b).

 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 
 (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, 4.17 and 4.18 hereof and clause (4) of Section 5.01 hereof with respect to the outstanding 

  
 97 

 
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, Section 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 (in each case assuming the payment of interest as Cash Interest through such 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, 

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; 

  
 98 

 (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. 
 All of the Collateral will be released from the Lien securing the Notes, as
provided under Section 13.05 hereof, upon a Legal Defeasance or Covenant Defeasance in accordance with the provisions described above. 

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. 

  
 99 

 Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to
the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent
Legal Defeasance or Covenant Defeasance. 
 Section 8.06 Repayment to Company. 

Subject to applicable abandoned property laws, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust
for the payment of the principal of, premium, if any, or interest on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Company on its request or (if
then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be
published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or
publication, any unclaimed balance of such money then remaining will be repaid to the Company. 
 Section 8.07 Reinstatement. 

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02
or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under this
Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on, any Note following the reinstatement of its obligations,
the Company will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 

ARTICLE 9 
 AMENDMENT, SUPPLEMENT
AND WAIVER 
 Section 9.01 Without Consent of Holders of Notes. 

Notwithstanding Section 9.02 of this Indenture, the Company, the Guarantors, the Trustee and the Collateral Trustee (if applicable with
respect to the Security Documents) may amend or supplement this Indenture, the Notes, the Note Guarantees or the other Note Documents without the consent of any Holder of Notes: 

(1) to cure any ambiguity, defect or inconsistency; 

  
 100 

 (2) to provide for uncertificated Notes in addition to or in place of certificated Notes;

 (4) to make any change that would provide any additional rights or benefits to
the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder; 
 (5) to provide for the issuance of Additional Notes
or PIK Interest Notes or to increase the outstanding principal amount of the Notes, in each case in accordance with the limitations set forth in this Indenture as of the date hereof; 

(6) to release or subordinate Liens on Collateral in accordance with the Note Documents; 

(7) to confirm and evidence the release, termination or discharge of any Lien with respect to or securing the Notes or the Note Guarantees when such release,

 (8) to allow any Guarantor to execute a
supplemental indenture and/or a Note Guarantee with respect to the Notes or release the Note Guarantees pursuant to the terms of this Indenture; 
 (9) to

 (10)
with respect to the Security Documents, as provided in the Intercreditor Agreement;

(13) to modify Section 2.06 solely for the purpose of providing for the removal of the Private Placement Legend from any Note and to allow for the

In addition, without the consent of any Holder, the Intercreditor Agreement and the Collateral Trust Agreement may be amended in accordance
with their terms, including to add additional Indebtedness as Priority Lien Debt, Second Lien Debt or Third Lien Debt and add other parties (or any authorized agent thereof or trustee therefor) holding such Indebtedness thereto and to establish that
the Liens on any Collateral securing such Indebtedness shall rank equally with the Liens on such Collateral securing the other Priority Lien Debt, Second Lien Debt or Third Lien Debt, as applicable, then outstanding. 

  
 101 

 Each Holder of Notes hereunder (x) consents to the amendment of any Note Document in the
manner and for the purposes set forth in this Section 9.01, (y) agrees that it will be bound by and will take no actions contrary to the provisions of any amendment to any Note Document pursuant to Section 9.01 and (z) authorizes

Upon the request of the Company, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join
with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but
the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 

Section 9.02 With Consent of Holders of Notes. 

Except as provided below in this Section 9.02, the Company, the Guarantors, the Trustee and the Collateral Trustee (if applicable with
respect to the Security Documents) may amend or supplement this Indenture (including, without limitation, Section 3.09, 4.10 and 4.14 hereof), the Notes, the Note Guarantees and the Security Documents with the consent of the Holders of at least

a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Section 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, the Notes, the Note Guarantees and the Security Documents 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 and PIK Interest 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 in the execution of such amended or supplemental indenture and will direct the
Collateral Trustee to execute any amendment or supplement to the Security Documents unless such amended or supplemental indenture or such Security Document amendment or supplement 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 and may but shall not be obligated to direct the Collateral Trustee to enter into such
amendment or supplement to the Security Documents.

 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 send 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 Section 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 bring suit for the
enforcement of 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 Section 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 the Note Documents; or 
 (9) make any change in the preceding amendment and waiver
provisions. 
 In addition, any amendment or supplement to, or waiver of, the provisions of this Indenture or any Note Document that has the
effect of releasing all or substantially all of the Collateral from the Liens securing the Notes will require the consent of the Holders of at least 66 2/3% in aggregate principal amount of the Notes then outstanding. 

  
 103 

 Section 9.03 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 9.04 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 9.05 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 

  
 104 

 (2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that
same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration, redemption or otherwise. 

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and
severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 
 (b) The
Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder
of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a
guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice
and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. 

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other
similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect. 

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby
until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed
hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and
(2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note
Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee. 

Section 10.02 Limitation on Guarantor Liability. 

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note
Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to
any Note Guarantee. To effectuate the foregoing intention, the Trustee, the 

  
 105 

 
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. 

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 this Indenture or a supplemental
indenture in substantially the form attached hereto as Exhibit E 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 a supplemental indenture no longer holds that office at the time the Trustee authenticates the Note, 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 reasonably satisfactory to the Trustee; or 

  
 106 

 (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. 

Except as set forth in Article 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 requested by the Company or such Guarantor 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 requested by the Company or such Guarantor in order to evidence the release of any Guarantor from
its obligations under its Note Guarantee. 

  
 107 

 (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. 
 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 (assuming the payment of interest as Cash Interest through such date); 

(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; 

  
 108 

 (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 Section 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 7.06 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 or Government Securities deposited with the Trustee pursuant to
Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent)
as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the
extent required by law. 
 If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with
Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s
obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Company has made any payment of principal of, premium, if any, or
interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest hereunder or be prejudicial to the interests of Holders or the Trustee. 

Section 13.04 Post-Issue Date Collateral Requirements. 

Notwithstanding anything to the contrary contained in this Indenture or the other Note Documents, the parties hereto acknowledge and agree
that the Company shall deliver, or cause one or more Guarantors to deliver, to the Collateral Trustee the following items within 30 days after the Issue Date:

subject to such Mortgage is located) and to the extent requested by the Collateral Trustee, at the direction of the holders of Third Lien Obligations in accordance with the terms of the applicable Third Lien Documents, corresponding UCC fixture
filings or as-extracted collateral filings (or, if UCC fixture filings and as-extracted collateral filings are not available in the applicable jurisdiction, equivalent filings as available in such jurisdiction), and any similar filings as shall be
required by local law, which Mortgages, UCC fixture filings or as-extracted collateral filings (or, in the case of UCC fixture filings and as-extracted collateral filings, any other equivalent filings, as available in each applicable jurisdiction)
or other similar filings shall cover each Mortgaged Property, together with evidence reasonably satisfactory to the Collateral Trustee that such Mortgages, UCC fixture filings or as-extracted collateral filings (or, in the case of UCC fixture
filings and as-extracted collateral filings, any other equivalent filings, as available in each applicable jurisdiction) or similar filings have been delivered to the Persons responsible for recording or filing, as applicable, of such Mortgages, UCC
fixture filings, as-extracted collateral filings, equivalent filings or similar filings, as the case may be; 

  
 115

Trustee, at the direction of the holders of Third Lien Obligations in accordance with the terms of the applicable Third Lien Documents; and 
 (c) legal

counsel with respect to the Mortgages, and (2) outside counsel to the Company of national standing, covering, without limitation, the due authorization, execution and delivery of the Mortgages with respect to Delaware and Texas laws, in each
case, in form and substance substantially equivalent to the opinions previously delivered to the Collateral Trustee. 
 The Company shall file a Current
Report on Form 8-K with the SEC within the applicable time period for such a filing, containing customary detail on such actions, upon completion of the deliveries referred to in this Section 13.04. 

Section 13.05 Intercreditor Agreement. 

This Article 13 and the provisions of each other Security Document are subject to the terms, conditions and benefits set forth in the
Intercreditor Agreement. The Company and each Guarantor consents to, and agrees to be bound by, the terms of the Intercreditor Agreement, as the same may be in effect from time to time, and to perform its obligations thereunder in accordance with
the terms thereof. Each Holder of Notes, by its acceptance of the Notes (a) consents to the subordination of Liens provided for in the Intercreditor Agreement, (b) agrees that it will be bound by, and will take no actions contrary to,
the provisions of the Intercreditor Agreement and (c) authorizes and instructs the Collateral Trustee (and the Trustee to direct the Collateral Trustee) on behalf of each Holder of Notes to enter into the Intercreditor Agreement as Third Lien
Collateral Trustee (as defined in the Intercreditor Agreement) on behalf of such Holders of Notes as Third Lien Secured Parties (as defined in the Intercreditor Agreement). In addition, each Holder of Notes authorizes and instructs the Collateral
Trustee to enter into any amendments or joinders to the Intercreditor Agreement, without the consent of any Holder or the Trustee, to add additional Indebtedness as Priority Lien Debt, Second Lien Debt or Third Lien Debt and add other parties (or
any authorized agent or trustee therefor) holding such Indebtedness thereto and to establish that the Lien on any Collateral securing such Indebtedness ranks equally with the Liens on such Collateral securing the other Priority Lien Debt, Second
Lien Debt or Third Lien Debt, as applicable, then outstanding. The foregoing provisions are intended as an inducement to the lenders under the Credit Agreement to extend credit to the Company and certain of its Subsidiaries, and such lenders
are intended third party beneficiaries of such provisions and the provisions of the Intercreditor Agreement. 
 Section 13.06 Collateral Trust
Agreement. 
 This Article 13 and the provisions of each Security Document are subject to the terms, conditions and benefits set forth
in the Collateral Trust Agreement. The Company and each Guarantor consents to, and agrees to be bound by, the terms of the Collateral Trust Agreement, 

  
 116 

 
as the same may be in effect from time to time, and to perform its obligations thereunder in accordance with the terms therewith. Each Holder of Notes, by its acceptance of the Notes
(a) agrees that it will be bound by, and will take no actions contrary to, the provisions of the Collateral Trust Agreement and (b) authorizes and instructs the Trustee, on behalf of each holder of Notes Obligations, to execute and deliver
the Collateral Trust Agreement (and to direct the Collateral Trustee to execute and deliver the Collateral Trust Agreement), which shall subject such holders of Notes Obligations to the terms of the Collateral Trust Agreement and to perform its
obligations thereunder as the Collateral Trustee and as Third Lien Representative. 
 Section 13.07 Release of Liens in Respect of Notes. 

The Collateral Trustee’s Third Liens upon the Collateral will no longer secure the Notes outstanding under this Indenture or any other
Notes Obligations, and the right of the Holders to the benefits and proceeds of the Collateral Trustee’s Liens on the Collateral will terminate and be discharged: 

(a) in whole, upon satisfaction and discharge of this Indenture in accordance with Article 11 hereof; 

(b) in whole, upon a Legal Defeasance or Covenant Defeasance of the Notes in accordance with Article 8 hereof; 

(c) in part, upon payment in full in cash and discharge of all Notes outstanding under this Indenture and all other Notes Obligations that are outstanding,
due and payable under this Indenture and the other Note Documents at the time the Notes are paid in full in cash and discharged (other than contingent indemnity obligations for which no claim has been made); 

(d) as to any Collateral of the Company or a Guarantor that is sold, transferred or otherwise disposed of by the Company or any Guarantor to a Person that is
not (either before or after such sale, transfer or disposition) the Company or a Restricted Subsidiary of the Company in a transaction or other circumstance that complies with Section 4.10 and is permitted by all of the other Note Documents, at
the time of such sale, transfer or other disposition or to the extent of the interest sold, transferred or otherwise disposed of; 
 (e) in whole or in
part, with the consent of the Holders of the requisite aggregate principal amount of Notes in accordance with Article 9 hereof; 
 (f) with respect to the
assets of any Guarantor, at the time that such Guarantor is released from its Note Guarantee in accordance with Section 10.05; or 
 (g) if and to the
extent required by Section 4.01 of the Intercreditor Agreement. 
 In addition, the Collateral Trustee’s Liens on the Collateral will be
released upon the terms and subject to the conditions set forth in Section 3.2 of the Collateral Trust Agreement. If the Priority Lien Obligations and Second Lien Obligations are repaid in full and the related commitments terminated thereunder
without being replaced, the Liens on the Collateral in favor of the Collateral Trustee for the benefit of itself, the Trustee and the Holders of the Notes and the other Third Lien Obligations will not be released at such time, except to the extent
the Collateral or 

  
 117 

 
any portion thereof was disposed of in order to repay the Obligations under the Priority Lien Obligations or the Second Lien Obligations secured by the Collateral in compliance with
Section 4.12 hereof. 
 Section 13.08 Additional Indebtedness. 

In connection with the incurrence by the Company or any Subsidiary thereof of any Priority Lien Obligations, Second Lien Obligations or Third
Lien Obligations permitted to be incurred pursuant to the terms hereof and of any other then outstanding Priority Lien Documents, Second Lien Documents and Third Lien Documents, Holders, by their acceptance of a Note, authorize and direct the
Trustee to execute and deliver (and to direct the Collateral Trustee to execute and deliver) any supplements, joinders or confirmations to the Intercreditor Agreement and Collateral Trust Agreement and any amendments, amendments and restatements,
restatements or waivers of or supplements to or other modifications to any Security Document (including but not limited to any Mortgages and UCC fixture filings), and to make or consent to any filings or take any other actions in connection
therewith, as may be reasonably deemed by the Company to be necessary or reasonably desirable for any Lien on the assets of the Company or any Subsidiary permitted to secure such Indebtedness to become a valid, perfected lien (with such priority as
may be designated by the Company, the relevant Guarantor or Subsidiary, to the extent such priority is permitted by the Note Documents) pursuant to the Security Document being so amended, amended and restated, restated, waived, supplemented or
otherwise modified or otherwise.

 A-5 

 (1) INTEREST. W&T Offshore, Inc., a Texas corporation (the “Company”), promises to pay Cash
Interest on the principal amount of this Note at 8.50% per annum (the “Cash Interest Rate”) from September 7, 20161 until maturity; provided, however, that
for any interest period ending on or prior to June 15, 20182, the Company may elect to pay all or any portion of interest in kind on the then outstanding principal amount of this Note at a
rate of 10.00% per annum (the “PIK Interest Rate”) by increasing the principal amount of the outstanding Notes or by issuing additional Notes (“PIK Interest Notes”) in a principal amount equal to such interest
(“PIK Interest”). The Company will pay interest semi-annually in arrears on June 15 and December 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest
Payment Date”). [The initial interest payment on December 15, 2016 will be made solely in PIK Interest at the PIK Interest Rate]3. On the December 15, 2018 Interest Payment
Date, the Company shall be permitted to make only part of the interest payment in PIK Interest at the PIK Interest Rate and part of the interest payment in Cash Interest at the Cash Interest Rate, provided, that PIK Interest to be paid on
such Interest Payment Date shall accrue only for the period from June 15, 2018 to, but not including, September 7, 2018, and any remaining interest for such period shall be payable solely in Cash Interest. Interest shall be payable entirely in
Cash Interest for all Interest Payment Dates after December 15, 2018. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that
if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding
Interest Payment Date; provided further that the first Interest Payment Date shall be December 15, 20164. The Company will pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate that is 1% per annum in excess of the rate then in effect 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 periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a
360-day year of twelve 30-day months. 
 (2) METHOD OF PAYMENT. Except as provided in Section (1) of this Note, interest on the Notes shall be
payable entirely in cash (“Cash Interest”). The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the June 1 or December 1
next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will
be payable as to principal, premium, if any, and Cash Interest at the office or agency of the Company maintained for such purpose within or without the City and State of New York, or, at the option of the Company, payment of Cash Interest may be
made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment of Cash Interest by wire transfer of immediately available funds will be required with respect to principal, interest, and
premium, if any, on, all Global Notes and all other Notes the Holders of 
  

	1 	For Additional Notes, insert the appropriate date for such Additional Notes. 

	2 	For Initial Notes and any Additional Notes issued prior to the date which is 24 months following the Issue Date. 

	3 	For Initial Notes and any Additional Notes issued prior to December 15, 2016. 

	4 	 For Additional Notes, insert the appropriate Interest Payment Date for such Additional Notes.

which will have provided wire transfer instructions to the Company or the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. 
 In connection with the payment of PIK Interest in respect of the Notes, the Company
shall be entitled, without the consent of the Holders thereof (and without regard to any restrictions or limitations set forth in Section 4.11 of the Indenture), to issue PIK Interest Notes by (i) increasing the outstanding principal
amount of the then authenticated Global Notes or (ii) by issuing Definitive Notes under the Indenture on the same terms and conditions as the Initial Notes (in each case, a “PIK Payment”). 

Notwithstanding anything to the contrary, the payment of accrued interest in connection with any redemption or repurchase of the Notes as
described under Sections 3.07, 4.10 or 4.14 of the Indenture will be made solely in Cash Interest. If the Company elects to pay interest on the Notes as a combination of Cash Interest and as PIK Interest, Cash Interest and PIK Interest shall be paid
on the Notes to the Holders on a pro rata basis. 
 PIK Interest on the Notes will be payable (x) with respect to Notes represented by
one or more Global Notes registered in the name of, or held by, DTC or its nominee on the relevant record date, by increasing the principal amount of the outstanding Global Note by an amount equal to the amount of PIK Interest for the applicable
interest period (rounded up to the nearest whole dollar) as provided in writing by an Officer of the Company to the Trustee and, upon receipt of such written order of the Company, the Trustee shall increase the Global Notes by the amount of PIK
Interest (or authenticate new Global Notes if required by the applicable procedures of the Depositary) and (y) with respect to Definitive Notes, by issuing PIK Interest Notes in certificated form in an aggregate principal amount equal to the
amount of PIK Interest for the applicable period (rounded up to the nearest whole dollar), and the Trustee shall, at the request of the Company and upon receipt of an Authentication Order, authenticate and deliver such PIK Interest Notes in
certificated form for original issuance to the Holders on the relevant record date, as shown by the records of the register of Holders. Following an increase in the principal amount of the outstanding PIK Interest Notes as a result of a payment of
PIK Interest, the PIK Interest Notes shall bear interest on such increased principal amount from and after the date of such payment. Any PIK Interest Notes issued in certificated form shall be dated as of the applicable Interest Payment Date and
shall bear interest from and after such date. All PIK Interest Notes issued pursuant to a payment of PIK Interest shall be governed by, and subject to the terms, provisions and conditions of, the Indenture and shall have the same rights and benefits
as the Notes issued on the Issue Date. Any certificated PIK Interest Notes shall be issued with the description “PIK” on the face of such PIK Interest Note. 

(3) PAYING AGENT AND REGISTRAR. Initially, Wilmington Trust, National Association, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity. 

(4) INDENTURE AND SECURITY DOCUMENTS. The Company issued the Notes under an Indenture dated as of September 7, 2016 (the “Indenture”)
among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture. The Notes are 

  
 A-7 

 
subject to all such terms, and Holders are referred to the Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the
Indenture, the provisions of the Indenture shall govern and be controlling. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder. The Notes and the Guarantees are secured by Third Liens on the Collateral
pursuant to the Security Documents. The rights of the Holders in the Collateral are subject to the terms of the Intercreditor Agreement and the Collateral Trust Agreement. 

(5) OPTIONAL REDEMPTION. 
 (a) Except as set forth in
subparagraphs (b), (c) and (d) of this Paragraph 5, the Company will not have the option to redeem the Notes prior to June 15, 2018. On or after June 15, 2018, the Company will have the option to redeem all or a part of the Notes
upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest on the Notes redeemed to the applicable redemption date, if redeemed
during the twelve-month period beginning on June 15 of the years indicated below, subject to the rights of Holders on the relevant record date to receive interest on the relevant Interest Payment Date: 

 

					
	 Year
	  	Percentage	 
	 2018
	  	 	104.250	% 
	 2019
	  	 	102.125	% 
	 2020 and thereafter
	  	 	100.000	% 

 Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on the Notes or portions
thereof called for redemption on the applicable redemption date. 
 (b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any
time prior to June 15, 2018, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes issued under the Indenture with an amount of cash equal to the net cash proceeds of one or more Equity
Offerings at a redemption price equal to 108.500% of the aggregate principal amount thereof, plus accrued and unpaid interest to the redemption date; provided that at least 65% in aggregate principal amount of the Notes originally issued
under the Indenture remains outstanding immediately after the occurrence of such redemption and that such redemption occurs within 90 days of the date of the closing of the related Equity Offering. 

(c) At any time prior to June 15, 2018, the Company may also redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ notice,
at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but not including the date of redemption, subject to the rights 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. 

  
 A-8 

 (d) In the event that Holders of not less than 90% of 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)) 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 to the Holders and the Trustee, 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). 
 (6) MANDATORY
REDEMPTION. 
 The Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes. 

(7) REPURCHASE AT THE OPTION OF HOLDER. 
 (e) If there is a
Change of Control, the Company will be required to make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of each Holder’s Notes at a purchase
price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest thereon to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest
Payment Date (the “Change of Control Payment”). Within 10 days following any Change of Control, the Company will mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the
Indenture. 
 (f) If the Company or a Restricted Subsidiary of the Company consummates any Asset Sales, within five days of each date on which the aggregate
amount of Excess Proceeds exceeds $20.0 million, the Company will commence an offer to all Holders of Notes and all holders of other Indebtedness that is pari passu in right of payment with the Notes containing provisions similar to those set
forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets (an “Asset Sale Offer”) pursuant to Section 3.09 of the Indenture to purchase on a pro rata basis the maximum principal
amount of Notes (including any Additional Notes) and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the original principal amount thereof plus
accrued and unpaid interest thereon to the date of purchase, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes (including any Additional Notes) and other pari passu Indebtedness
tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company (or such Restricted Subsidiary) may use such deficiency for any purpose not otherwise prohibited by the 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). Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company prior to any related
purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes.

be an enforceable and perfected third-priority Lien, which failure is not cured within 45 days, and (x) 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

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

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 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.
