 “Acquired Debt” means, with respect to any specified Person: 

(1) Indebtedness of any other Person existing at the time such other Person is merged with or into or became a Subsidiary of
such specified Person, whether or not such Indebtedness is incurred in connection with, or in contemplation of, such other Person merging with or into, or becoming a Restricted Subsidiary of, such specified Person, but excluding Indebtedness which

the Company from any Joint Venture) in a Reserve Report prepared as of the end of the fiscal year ending at least 91 days prior to the date of determination (or as of June 30 ending at least 45 days prior to the date of determination, if the
Company elects to prepare a mid-year Reserve Report) as increased by, as of the date of determination, the discounted future net revenue of:

 6 

 
development or exploitation, production or other activities which reserves were not reflected in such Reserve Report which would, in accordance with standard industry practice, result in such
determinations, in each case calculated in accordance with SEC guidelines (including utilizing the prices under SEC guidelines applicable to a Reserve Report as of its date), 

and decreased by, as of the date of determination, the discounted future net revenue attributable to: 

(iii) estimated proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries reflected in such
Reserve Report produced or disposed of since the date of such Reserve Report, and 
 (iv) reductions in the estimated oil
and natural gas reserves of the Company and its Restricted Subsidiaries reflected in such Reserve Report since the date of such Reserve Report attributable to downward determinations of estimates of proved crude oil and natural gas reserves due to
exploration, development or exploitation, production or other activities conducted or otherwise occurring since the date of such Reserve Report which would, in accordance with standard industry practice, result in such determinations, in each case
calculated in accordance with SEC guidelines (including utilizing the prices under SEC guidelines applicable to a Reserve Report as of its date);

available annual or quarterly financial statements; 
 (c) the Net Working Capital (excluding, to the extent included in the
determination of discounted future net revenues under clause (1)(a) above, any adjustments made pursuant to FASB ASC Topic 410-20 as of a date no earlier than the date of the Company’s latest

(2) the sum of: 

(a) Minority Interests; 

(b) any net natural gas balancing liabilities of the Company and its Restricted Subsidiaries reflected in the Company’s
latest audited financial statements; 
 (c) to the extent included in clause (1)(a) above, the discounted future net
revenue, calculated in accordance with SEC guidelines (including utilizing the same prices in the Company’s Reserve Report used for this definition), attributable to reserves subject to participation interests, overriding royalty interests or
other interests of third parties, pursuant to participation, partnership, vendor financing or other agreements then in effect, or which otherwise are required to be delivered to third parties (excluding any interests subject to escrow arrangements
in connection with financial assurance requirements for plugging and abandonment obligations of the Company and its Restricted Subsidiaries); 

(d) to the extent included in clause (1)(a) above, the discounted future net revenue calculated in accordance with SEC
guidelines (including utilizing the same prices in the Company’s Reserve Report used for this definition), attributable to reserves that are required to be delivered to third parties to fully satisfy the obligations of the Company and its
Restricted Subsidiaries with respect to Volumetric Production Payments on the schedules specified with respect thereto; and 

(e) the discounted future net revenue, calculated in accordance with SEC guidelines, attributable to reserves subject to
Dollar-Denominated Production Payments that, based on the estimates of production included in determining the discounted future net revenue specified in the immediately preceding clause (1)(a) (utilizing the same prices in the Company’s Reserve
Report used for this definition), would be necessary to satisfy fully the obligations of the Company and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments on the schedules specified with respect thereto. 

If the Company changes its method of accounting from the full cost method to the successful efforts method or a similar method of accounting,
“Adjusted Consolidated Net Tangible Assets” will continue to be calculated as if the Company were still using the full cost method of accounting.

thereof. 

  
 47 

 The terms and provisions contained in the Notes will constitute, and are hereby expressly
made, a part of this Indenture and the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note
conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling. 
 (b) Global
Notes. Notes issued in global form will be substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued
in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will
represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of
outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal
amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof. 

Section 2.02 Execution and Authentication. 

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

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be
valid. 
 A Note will not be valid until authenticated by the manual signature of the Trustee. The signature will be conclusive evidence
that the Note has been authenticated under this Indenture. 
 The Trustee will, upon receipt of a written order of the Company signed by at
least one Officer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The aggregate principal amount of Notes outstanding at any time
may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof. 

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

more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any
additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to
appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar. 

The Company initially appoints DTC to act as Depositary with respect to the Global Notes.

The place of payment with respect to the Notes, in addition to the Corporate Trust Office of the Trustee, shall be 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 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. 

  
 49 

 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.

the Company for Definitive Notes if:

notice from the Depositary; 
 (2) the Company in its sole discretion determines that the Global Notes (in whole but not in
part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee; or 
 (3) there
has occurred and is continuing a Default or Event of Default with respect to the Notes. 
 Upon the occurrence of any of the preceding
events in (1), (2) or (3) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10
hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or Section 2.10 hereof, shall be authenticated and delivered in the
form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in

 (1)
Private Placement Legend. 
 (A) Except as permitted by subparagraph (B) below, each Global Note and each Definitive
Note (and all Notes issued in exchange therefor or substitution thereof) shall bear the legend in substantially the following form: 
 “THIS NOTE HAS
NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET

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 SECURITIES ACT) (AN “INSTITUTIONAL ACCREDITED INVESTOR”), (2) AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS NOTE EXCEPT (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES TO A
QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT (IF AVAILABLE), (D) INSIDE THE UNITED STATES

CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS NOTE (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM THE TRUSTEE) AND IF SUCH TRANSFER IS IN

THIS NOTE IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF THIS NOTE, THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT
THIS CERTIFICATE TO THE TRUSTEE. IF THE PROPOSED TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE AND THE COMPANY SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS EITHER
OF THEM MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. AS USED HEREIN, THE TERMS “OFFSHORE

NOTE IN VIOLATION OF THE FOREGOING RESTRICTIONS.” 
 (B) Notwithstanding the foregoing, any Global Note or Definitive
Note issued pursuant to subparagraphs (b)(4), (c)(2), (c)(3), (d)(2), (d)(3), (e)(2) or (e)(3) of this Section 2.06 (and all Notes issued in exchange therefor or substitution thereof) will not bear the Private Placement Legend.

TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.11 OF THE INDENTURE AND (4) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY. 

UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR NOTES IN DEFINITIVE FORM, THIS NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A
NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY. UNLESS THIS CERTIFICATE

REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF

(g) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been
exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with Section 2.11
hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive
Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and
if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased accordingly and an endorsement will be
made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. 
 (h) General
Provisions Relating to Transfers and Exchanges. 
 (1) To permit registrations of transfers and exchanges, the Company
will execute and the Trustee will authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request. 

  
 59 

 (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, 4.11 or 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. 
 (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

and the next succeeding Interest Payment Date. 
 (6) Prior to due presentment for the registration of a transfer of any
Note, the Trustee, any Agent, the Company and the Guarantors may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of, premium, if any, and interest on
such Notes and for all other purposes, and none of the Trustee, any Agent, or the Company and the Guarantors shall be affected by notice to the contrary. 

(7) The Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02
hereof. 

  
 60

(9) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on
transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants or beneficial owners of 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. 

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. 

  
 61 

 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.

 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 by lot (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.

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. 

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 such redemption is subject to the satisfaction of one of more
conditions precedent, such notice shall describe such condition and, if applicable, shall state that, in the Company’s discretion, the redemption date may be delayed (subject to the first paragraph of this Section 3.03) until such time as
any or all such conditions shall be satisfied (or waived by the Company in its sole discretion), or that such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or
waived by the Company in its sole discretion) by the redemption date, or by the redemption date so delayed, or that such notice may be rescinded at any time in the Company’s discretion if in the good faith judgment of the Company any or all of
such conditions will not be satisfied; 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 (or such shorter period as shall
be acceptable to the Trustee), 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. 

Section 3.05 Deposit of Redemption or Purchase Price. 

By 11:00 a.m. Eastern Time on the redemption or purchase date, the Company will deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption or purchase price of and accrued interest on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Company any money deposited with the Trustee or the Paying
Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest on, all Notes to be redeemed or purchased. 

If the Company complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to
accrue on the Notes or the portions of Notes called for redemption or tendered for purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related Interest Payment Date, then any accrued and unpaid
interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or tendered for purchase is not so paid upon surrender for redemption or purchase because of
the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or tendered for purchase date until such principal is paid, and to the extent lawful on any interest not paid on
such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 
 Section 3.06 Notes Redeemed or Purchased
in Part. 
 Upon surrender of a Note that is redeemed or purchased in part, the Company will issue and, upon receipt of an Authentication
Order, the Trustee will authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered. 

Section 3.07 Optional Redemption.

of Notes issued under this Indenture at a redemption price of 109.750% 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

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

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

redemption (subject to the right of Holders on the relevant record date to receive interest due on the relevant Interest Payment 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 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 the relevant Interest Payment Date).

pursuant to the provisions of Section 3.01 through 3.06 hereof. 

  
 66 

 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 4.11 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 (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 containing provisions similar to those set forth in this Indenture with respect to offers to purchase, repay 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 Indebtedness (on a pro rata basis based on
the outstanding amount of the Notes and such other Indebtedness, 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 4.11 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. 

  
 67 

 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 4.11 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 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 Indebtedness will select such other Indebtedness to be purchased on a pro
rata basis based on the principal amount of Notes and such other Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $1,000, or integral multiples thereof, will be
purchased); and 
 (9) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal
amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer). 

  
 68 

 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 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. 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. 

  
 69 

 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. 
 Section 4.03 Reports. 

(a) So long as any Notes are outstanding, the Company will file with the SEC for public availability, within 30 days of the time periods

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 such 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 in paragraph (a) of this Section 4.03 with the SEC within the time periods specified above unless the SEC will not accept such a filing. The Company will not take any action for the
purpose of causing the SEC not to accept any such filings. If, notwithstanding the foregoing, the SEC will not accept the Company’s filings for any reason, the Company will post the reports referred to in paragraph (a) of this
Section 4.03 on its website within 30 days of the time periods that would apply if the Company were required to file those reports with the SEC.

then, to the extent material as determined by the Board of Directors of the Company in good faith, the quarterly and annual financial information required by paragraph (a) of this Section 4.03 will include a reasonably detailed

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’

 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.

Consolidated Net Income; plus 
 (D) 100% of any dividends received by the Company or a Restricted Subsidiary of the

satisfy the Company’s or such Restricted Subsidiary’s tax withholding obligation with respect to such exercise or vesting; 

  
 75 

 (7) so long as no Default has occurred and is continuing or would be caused

Subordinated Obligations in the event of an Asset Sale, in each case plus accrued and unpaid interest, in connection with any change of control offer or asset sale offer required by the terms of such Subordinated Obligations, but only if: 

(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 4.11 (including without limitation the repurchase of all Notes validly tendered for payment in connection therewith);

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 in an amount up to $35.0 million for each 12-month period
following the Issue Date, with any unused portion of such amount in any such period to be carried forward to succeeding 12-month periods; provided that if the Senior Secured Leverage Ratio is greater
than 2.00:1.00 on any anniversary of the Issue Date, such amount shall be limited to $15.0 million for the subsequent 12-month period;

(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 4.08 will be evidenced by an Officers’ Certificate delivered to the 

  
 76 

 
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 4.08. For purposes of determining compliance with this Section 4.08, 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 4.08, 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 4.08. 

Section 4.09 Dividend and Other Payment Restrictions Affecting Subsidiaries. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or
become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

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

(2) this Indenture, the Notes, 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; 

  
 77 

 (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 4.09(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 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 4.13 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 4.10; provided that the provisions of such agreement relating to such dividend and other payment encumbrances or restrictions taken as a whole are not materially more
restrictive, as determined by the Board of Directors or the Company in good faith, than those provisions contained in the agreements governing Existing Indebtedness and the Credit Agreement, in each case as in effect on the Issue Date; 

(11) the issuance of preferred stock by a Restricted Subsidiary or the payment of dividends thereon in accordance with the
terms thereof; provided that issuance of such preferred stock was made in accordance with Section 4.10 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);

 Section 4.10 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 4.10(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 greatest of: 

(i) $300.0 million; and 

(ii) 20% 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; and 

  
 79 

 (iii) the Borrowing Base at the time of incurrence; 

provided that if the lenders under each Credit Facility incurred under this clause (1) do not include at least one commercial bank that provides,
in the ordinary course of its business, reserve-based bank loans in the Oil and Gas Business, then the aggregate amount that may be incurred under this clause (1) shall not exceed $300.0 million; 

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

(3) the incurrence by the Company and the Guarantors of Indebtedness represented by the Notes and the related Note Guarantees
to be issued on the Issue Date ; 
 (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 at any time outstanding, 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 the greater of (a) $30.0 million and (b) 2.0% of Adjusted Consolidated Net Tangible Assets determined as of the date of the incurrence
of such Indebtedness; 
 (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 4.10(a) hereof or clauses (2), (3), (4) or (11) of this Section 4.10(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); 

  
 80 

 (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 4.10; 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; 

  
 81 

 (15) the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness in respect of bid, performance, surety and similar bonds (including reimbursement obligations with respect thereto) issued for the account of the Company and any of its Restricted Subsidiaries in the ordinary course of business, and
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); 

(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 the greater of (a) $60.0 million and (b) 4.0% of Adjusted Consolidated Net Tangible Assets determined as of the date of the incurrence of such
Indebtedness; and 
 (17) the incurrence by the Company or any of its Restricted Subsidiaries of any Indebtedness recourse
only to the Income Tax Refund Claim (subject to customary recourse exceptions). 
 (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 4.10, 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
(17) above or is entitled to be incurred pursuant to Section 4.10(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 4.10; provided that any Indebtedness outstanding on the Issue Date incurred under the Credit 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 4.10;
provided, in each such case, that 

  
 82 

 
the amount thereof is included in Fixed Charges of the Company as accrued. Notwithstanding any other provision of this Section 4.10, the maximum amount of Indebtedness that the Company or
any Restricted Subsidiary may incur pursuant to this Section 4.10 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. 

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

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

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

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

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

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

Section 4.11 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 15% 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; 

  
 83 

 (C) any stock or assets of the kind referred to in clauses (2) or
(3) of the next paragraph of this Section 4.11; 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 365 days after the receipt of any Net Proceeds from an Asset
Sale, or, if within such 365-day period the Company has entered into a binding commitment or commitments with respect to the actions described in clauses (2) or (3) below, within 180 days after the
entry into such binding commitment or commitments (or if later, 365 days after receipt of such 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 or 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, repayment or repurchase of outstanding Parity Lien Debt or by an offer to purchase on a
pro rata basis made to all holders of Parity Lien Debt 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 a
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) to 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 4.11(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 

  
 84 

 
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), subject to adjustment to maintain authorized minimum denominations. 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 4.11, 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 4.11 by virtue of such compliance. 
 (e) Notwithstanding paragraphs (a) and (b) of this Section 4.11, the
Company and its Restricted Subsidiaries will be permitted to consummate an Asset Sale without complying with such clauses to the extent that: 

(1) the consideration for such Asset Sale constitutes Additional Assets and/or the assumption of obligations secured by Liens
that burden some or all of the assets being sold and/or cash or Cash Equivalents; provided that, in the case of any such assumption, (a) the Person assuming such obligations shall have no recourse with respect to such obligations to the
Company or any of its Restricted Subsidiaries and (b) no assets of the Company or any of its Restricted Subsidiaries (other than those assets being sold) are subject to such Liens; and 

(2) such Asset Sale is for Fair Market Value; provided that at least 75% of the total consideration received by the
Company or any of its Restricted Subsidiaries in connection with any such Asset Sale shall be in the form of Additional Assets, the assumption of obligations secured by Liens described in clause (e)(1) above, cash or Cash Equivalents (including,
without limitation, assets deemed cash pursuant to clause (a)(2) above), or any combination of the foregoing, and that any Net Proceeds so received shall be subject to paragraphs (a) and (b) of this Section 4.11. 

  
 85 

 Section 4.12 Transactions with Affiliates. 

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

(2) the Company delivers to the Trustee: 

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in
excess of $10.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with this Section 4.12(a); and 

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in
excess of $30.0 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 4.12 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 4.12(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; 

  
 86 

 (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 4.08 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, delivers 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 4.12(a); 

(11) the performance of obligations of the Company or any of its Restricted Subsidiaries under the terms of any written
agreement to which the Company or any of its Restricted Subsidiaries is a party on the Issue Date and which is described in the Company’s offering memorandum relating to the Initial Notes, as these agreements may be amended, modified or
supplemented from time to time; provided, however, that any future amendment, modification or supplement entered into after the Issue Date will be permitted to the extent that its terms do not materially and adversely affect the rights
of any Holders of the Notes (as determined in good faith by the Board of Directors of the Company) as compared to the terms of the agreements in effect on the Issue Date; and 

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

  
 87 

 Section 4.13 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 4.14 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 but excluding the date of purchase, subject to the right of Holders on an record date to receive interest due on the relevant Interest Payment Date (the
“Change of Control Payment”). Within 30 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 sent (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 

  
 88 

 (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, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under 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 thereof 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 thereof 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. 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) a 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. 

  
 89 

 (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 4.15 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 4.08 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 4.15 and was
permitted by Section 4.08 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements of this Section 4.15 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 4.10 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 4.10 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 4.16 Additional Note Guarantees and Collateral. 

(a) If, after the Issue Date, any Domestic Subsidiary that is a Wholly-Owned 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 to the Trustee 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
Security Documents (other than the Intercreditor Agreement and the Collateral Trust Agreement) 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) In addition, 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 (including the filing of any financing statements and recording of any Mortgages) 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. 
 (c) 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, if and to the extent that any Priority Lien Document 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 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), 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 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 

  
 91 

 
deliverables as those delivered to the Priority Lien Representative 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 4.16(c) shall not be required. 

(d) The Company will deliver to the Collateral Trustee semi-annually on or before May 1 and November 1 in each calendar year,
beginning May 1, 2019, an Officers’ Certificate certifying that, as of the date of such certificate, the Collateral includes Oil and Gas Properties that include not less than 85% (or such greater amount as may be required by the 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 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; provided further that any such Mortgages and related items required to be delivered on the Issue Date may be delivered
no later than 90 days following the Issue Date (subject to extension with the Collateral Trustee’s reasonable consent, not to be unreasonably withheld or delayed; it being understood that the Collateral Trustee shall be deemed to have
provided its consent to any such extension to the extent a corresponding extension is provided by the Priority Lien Agent). 
 (e)
Notwithstanding anything herein or in the other 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 4.17 Termination of Covenants. 

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

(i) Section 4.08; 

  
 92 

 (ii) Section 4.09; 

(iii) Section 4.10; 
 (iv)
Section 4.11; 
 (v) Section 4.12; 

(vi) Section 4.15; 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 4.15 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. 

ARTICLE 5 
 SUCCESSORS 

Section 5.01 Merger, Consolidation, or Sale of Assets. 

The Company shall not, directly or indirectly: (i) consolidate or merge with or into another 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 

(B) the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale,
assignment, transfer, conveyance or other disposition has been made is a corporation, limited liability company or limited partnership organized or existing under the laws of the United States, any state of the United States or the District of
Columbia; 
 (2) the Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person
to which such sale, assignment, transfer, conveyance or other disposition has been made assumes all the obligations of the Company under the Notes, this Indenture and the other Note Documents; provided that, unless such Person is a
corporation, a corporate co-issuer of the Notes will be added to this Indenture by a supplemental indenture. 

  
 93 

 (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, transfer, conveyance or other disposition has been made, would, on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred
at the beginning of the applicable four-quarter period, (a) be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.10(a) hereof or (b) have a Fixed

other Note Documents.

all or substantially all of the properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and
assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company. 

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.

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, 4.11, 4.14 or 5.01 hereof; 
 (4) failure by the Company or any of its Restricted Subsidiaries for 60 days
after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class to comply with any of the other agreements in this Indenture; 

(5) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or
evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is
created after the Issue Date, if that default: 
 (A) is caused by a failure to pay principal of, or interest or premium, if
any, on, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or 

(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 $50.0 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; 

  
 95 

 (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 $50.0 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:

(D) makes a general assignment for the benefit of its creditors, or 

(E) generally is not paying its debts as they become due; 

(8) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(A) is for relief against the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of
Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary in an involuntary case; 

(B) appoints a custodian of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of
Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group
of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; or 
 (C) orders
the liquidation of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; 

  
 96 

 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 $25.0 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 $25.0 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. 

  
 97 

 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. 

  
 98 

 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
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 

  
 99 

 
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 or property pursuant to this Article 6, it shall pay out the money or property 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 

(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 the Trustee against any loss, liability or expense. 

  
 101 

 (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. 

(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, and if requested, provided 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. 

  
 102 

 (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. 

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. 

  
 103 

 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
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 (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. 

  
 104 

 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. 

(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. 

  
 105 

 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 instruments reasonably requested by the
Company acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder: 

  
 106 

 (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 and 4.16 hereof and clause (4) of Section 5.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant
Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants,
but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to
the outstanding Notes and Note Guarantees, the Company and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of
any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under
Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Section 6.01(3) through (6) and Section 6.01(9) 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 

  
 107 

 
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, or interest and premium on,
the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to such stated date for payment or to a particular redemption
date; 
 (2) in the case of an election under Section 8.02 hereof, the Company must deliver to the Trustee an Opinion of
Counsel reasonably acceptable to the Trustee 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 reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of
such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or
Event of Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party
or by which the Company or any Guarantor is bound; 
 (5) such Legal Defeasance or Covenant Defeasance will not result in a
breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 

(6) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company
with the intent of preferring the Holders of Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others; and 

 

  
 108 

 (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 or property 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 

  
 109 

 
thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money or property, 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 or property 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 or property 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

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

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

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

 110 

 (5) to conform the text of this Indenture, the Notes, the Note Guarantees or
the other Note Documents to any provision of the “Description of Notes” section of the Company’s offering memorandum relating to the Initial Notes, to the extent that such provision in the “Description of Notes” was intended
to be a verbatim or substantially verbatim recitation of a provision of this Indenture, the Notes, the Note Guarantees or the other Note Documents; 

(6) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture as of the
date hereof; 
 (7) to subordinate Liens on Collateral in accordance with the Note Documents;

Security Documents establishing Parity Liens (including to secure Parity Lien Obligations permitted to be incurred and secured under this Indenture); or 

(13) to evidence and provide for the acceptance under this Indenture of a successor Trustee. 

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 or Parity 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 or Parity Lien Debt, as applicable, then outstanding. 

  
 111 

 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. 

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, 4.11, 4.14, and 4.15 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 Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for,
or purchase of, the Notes), and, subject to 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 Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the
Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02. 

Upon the request of the Company, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of
Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Company and the Guarantors 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. 

  
 112 

 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, 4.11 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 interest or premium 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 on, the Notes; 
 (7)
waive a redemption payment with respect to any Note (other than a payment required by Section 3.09, 4.11 or 4.14 hereof); 

(8) release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the
terms of this Indenture; or 
 (9) make any change in the preceding amendment and waiver provisions. 

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. 

  
 113 

 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 

  
 114 

 (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. 

  
 115 

 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. 
 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 4.16 hereof, the Company will cause such Domestic Subsidiary to comply with the provisions of Section 4.16 hereof and this Article 10, to the extent applicable.

 Section 10.04 Guarantors May Consolidate, etc., on Certain Terms. 

Except as otherwise provided in Section 10.05 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets
to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless: 

(1) immediately after giving effect to such transaction, no Default or Event of Default exists; and 

  
 116 

 (2) either: 

(a) subject to Section 10.05 hereof, the Person acquiring the assets in any such sale or disposition or the Person formed
by or surviving any such consolidation or merger (if other than the Company or another Guarantor) unconditionally assumes pursuant to a supplemental indenture substantially in the form attached as Exhibit E hereto, all the
obligations of such Guarantor under this Indenture, its Note Guarantee and the other Note Documents; or 
 (b) such
transaction does not violate Section 4.11 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 Articles 4 and 5 hereof, and notwithstanding clauses (2)(a) and (b) above, nothing contained in this Indenture or
in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the
Company or another Guarantor. 
 Section 10.05 Releases. 

(a) In the event of any sale or other disposition of all or substantially all of the assets of any Guarantor (including by way of merger or
consolidation) 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 assets will be released and relieved of any obligations under its
Note Guarantee; provided that such transaction does not violate Section 4.11 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 4.11 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. 

  
 117 

 (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 4.11 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 4.11 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 upon 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. 

In addition, the Collateral Trustee’s Lien on the Collateral will be released upon the terms and subject to the conditions set forth in
the Collateral Trust Agreement. 
 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 

  
 118 

 (b) all Notes that have not been delivered to the Trustee for cancellation
have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust
funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any
reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption; 

(2) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of
Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by
which the Company or any Guarantor is bound; 
 (3) the Company or any Guarantor has paid or caused to be paid all sums
payable by it under this Indenture; and 
 (4) the Company has delivered irrevocable instructions to the Trustee under this
Indenture to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be. 
 In
addition, the Company must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. 

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause
(b) of clause (1) of this Section 11.01, the provisions of 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. 

  
 119 

 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.

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

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. 

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 90 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 Credit Agreement Agent, 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 Credit Agreement Agent 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, to the
extent requested by the Credit Agreement Agent; 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

 126 

 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 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 or Parity 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 or Parity 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. 

  
 127 

 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; 

(c) 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 is not prohibited by Section 4.11, at the time of such sale,
transfer or other disposition or to the extent of the interest sold, transferred or otherwise disposed of; 
 (d) 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; 
 (e) 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 

(f) 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 4.11 hereof. 
 Section 13.08 Additional Indebtedness.

 In connection with the incurrence by the Company or any Subsidiary thereof of any Priority Lien Obligations or Parity Lien Obligations
permitted to be incurred pursuant to the terms hereof and of any other then outstanding Priority Lien Documents and Parity 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

  
 128 

 
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.

 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 interest on the
principal amount of this Note at 9.75% per annum from                  until maturity. The Company will pay interest semi-annually in arrears
on May 1 and November 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue

  
 A-5 

 
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                 . 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. 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 April 15 or October 15
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 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 interest may be made by check
mailed to the Holders at their addresses set forth in the register of Holders; provided that payment 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 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. 
 (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
October 18, 2018 (the “Indenture”) among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture. The Notes are 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. 

  
 A-6 

 (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 November 1, 2020. On or after November 1, 2020, 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, but not including, the applicable redemption date (subject to the right of Holders on the relevant record date to receive
interest on the relevant Interest Payment Date), if redeemed during the 12-month period beginning on November 1 of the years indicated below: 

 

					
	 Year
	  	Percentage	 
	 2020

	 2021
	  	 	102.438	% 
	 2022
	  	 	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 November 1, 2020, 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 not greater than the net cash proceeds of one or more Equity Offerings at a redemption price equal to 109.750% of the aggregate principal amount thereof, plus accrued and unpaid interest to, but not including, 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 each such redemption occurs within 90 days of the
date of the closing of the related Equity Offering. 
 (c) At any time prior to November 1, 2020, 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 right of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date). 

(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) of the Indenture) 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 

  
 A-7 

 
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 the relevant Interest Payment 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, 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 but excluding the date of purchase, subject to the right of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date (the
“Change of Control Payment”). Within 30 days following any Change of Control, the Company will send 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 make an offer (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 containing provisions similar to
those set forth in the Indenture with respect to offers to purchase, repay or redeem with the proceeds of sales of assets pursuant to Section 3.09 of the Indenture, to purchase or repay on a pro rata basis the maximum principal amount of
Notes and such other 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 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), subject to adjustment to maintain authorized minimum denominations. Upon completion of each Asset Sale Offer, the
amount of Excess Proceeds will be reset at zero. 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-8 

 (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. The Notes are
in registered form without coupons in minimum denominations of $1,000 and integral multiples of $1,000 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. 
 (10)
PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes. 

(11) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture,
the Notes, the Note Guarantees or the Security Documents may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including Additional Notes, if any) voting as
a single class, and 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 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 class. Without the consent of any Holder of a Note, the Indenture, the Notes, the Note Guarantees or the Security Documents may be amended or supplemented: (i) to cure any ambiguity,
defect or inconsistency; (ii) to provide for uncertificated Notes in addition to or in place of certificated Notes; (iii) to provide for the assumption of the Company’s or a Guarantor’s obligations to Holders of the Notes and
Note Guarantees in case of a merger or consolidation; (iv) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such
Holder; (v) to conform the text of the Indenture, the Notes, the Note Guarantees or the other Note Documents to any provision 

  
 A-9 

 
of the “Description of Notes” section of the Company’s offering memorandum relating to the Initial Notes, to the extent that such provision in the “Description of Notes”
was intended to be a verbatim or substantially verbatim recitation of a provision of the Indenture, the Notes, the Note Guarantees or the other Note Documents; (vi) to provide for the issuance of Additional Notes; (vii) to subordinate
Liens on Collateral in accordance with the Note Documents; (viii) 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 the Indenture and the other Note Documents; (ix) 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 the Indenture; (x) to add any Collateral as provided in the Indenture or the other Note Documents, as applicable; (xi) with respect to the Security Documents, as provided in the Intercreditor Agreement; (xii) to make,
complete or confirm any grant of Collateral permitted or required by the Indenture or any of the Security Documents establishing Parity Liens (including to secure Parity Lien Obligations permitted to be incurred and secured under the Indenture); or
(xiii) to evidence and provide for the acceptance of a successor Trustee. 
 (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 (at maturity, upon redemption or otherwise) of the principal of, or premium, if
any, on, the Notes; (iii) failure by the Company or any of its Restricted Subsidiaries to comply with Sections 3.09, 4.11, 4.14 or 5.01 of the Indenture; (iv) 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 the Indenture; (v) default under certain
other agreements relating to Indebtedness for money borrowed of the Company or any of its Restricted Subsidiaries, which default results in the acceleration of such Indebtedness prior to its express maturity; (vi) failure by the Company or any
of its Restricted Subsidiaries to pay certain final judgments that remain undischarged for a period of 60 days; (vii) certain events of bankruptcy or insolvency with respect to the Company or any of its Restricted Subsidiaries that is a
Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary; (viii) except as permitted by the Note Documents, any Security Document establishing the Parity Liens ceases for any
reason to be enforceable with respect to any Collateral having a fair market value of not more than $25.0 million, which failure is not cured within 45 days; (ix) 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 $25.0 million, ceases to be an enforceable and perfected second-priority Lien, which failure is not cured within 45
days; (x) the Company or any Guarantor, or any Person acting on behalf of any of them, denies or disaffirms its obligations set forth in or arising under any Note Document establishing Parity Liens; and (xi) except as permitted by any Note
Document, 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 its
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

  
 A-10 

 
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.
