 INDENTURE, dated as of February 9, 2011, among GMX Resources Inc., an Oklahoma
corporation (the “Issuer”), the Subsidiary Guarantors (as hereinafter defined) and The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee”). 

The Issuer has duly authorized the creation of an issue of 11.375% Senior Notes due 2019 (the “Notes”) and, to provide
therefor, the Issuer and the Subsidiary Guarantors have duly authorized the execution and delivery of this Indenture. All things necessary to make the Notes, when duly issued and executed by the Issuer, and authenticated and delivered under this
Indenture, the valid obligations of the Issuer, and to make this Indenture a valid and binding agreement of the Issuer, have been done. 
 Each party hereto agrees as follows for the benefit of the other party and for the equal and ratable benefit of the Holders of the Notes. 

ARTICLE I. 

DEFINITIONS AND INCORPORATION BY REFERENCE 
 SECTION 1.1. Definitions. 
 “Acquired Indebtedness”
means Indebtedness (i) of a Person or any of its Subsidiaries existing at the time such Person becomes or is merged with and into a Restricted Subsidiary or (ii) assumed in connection with the acquisition of assets from such Person, in
each case whether or not Incurred by such Person in connection with, or in anticipation or contemplation of, such Person becoming a Restricted Subsidiary or such acquisition. Acquired Indebtedness shall be deemed to have been Incurred, with respect
to clause (i) of the preceding sentence, on the date such Person becomes or is merged with and into a Restricted Subsidiary and, with respect to clause (ii) of the preceding sentence, on the date of consummation of such acquisition of
assets. 
 “Additional Assets” means: 

(1) any properties or assets (other than Indebtedness and Capital Stock) to be used by the Issuer or a Restricted
Subsidiary in the Oil and Gas Business; 
 (2) capital expenditures by the Issuer or a Restricted Subsidiary in
the Oil and Gas Business; 
 (3) the Capital Stock of a Person that becomes a Restricted Subsidiary as a result
of the acquisition of such Capital Stock by the Issuer or a Restricted Subsidiary; or 

 (4) Capital Stock constituting a minority interest in any Person that at
such time is a Restricted Subsidiary; 
 provided, however, that, in the case of clauses (3) and (4), such Restricted Subsidiary is
primarily engaged in the Oil and Gas Business. 
 “Additional Notes” means Notes, in addition to, and having
identical terms (except for a date of original issuance different than the Issue Date) as, the $200,000,000 aggregate principal amount of Notes issued on the Issue Date, issued pursuant to Article II and in compliance with Section 4.12.

 “Adjusted Consolidated Net Tangible Assets” of a Person means (without duplication), as of the date of
determination, the remainder of: 
 (a) the sum of: 

(i) discounted future net revenues from proved oil and gas reserves of such Person and its Restricted Subsidiaries
calculated in accordance with SEC guidelines before any state or federal income taxes, as estimated by the Issuer in a reserve report prepared as of the end of the Issuer’s most recently completed fiscal year for which audited financial
statements are available, as increased by, as of the date of determination, the estimated discounted future net revenues from 
 (A) estimated proved oil and gas reserves acquired since such year end, which reserves were not reflected in such year end reserve report, and 

(B) estimated oil and gas reserves attributable to extensions, discoveries and other additions and upward revisions of
estimates of proved oil and gas reserves (including previously estimated development costs Incurred during the period and the accretion of discount since the prior period end) since such year end due to exploration, development or exploitation,
production or other activities which would, in accordance with standard industry practice, cause such revisions, in each case calculated in accordance with SEC guidelines (utilizing the prices for the fiscal quarter ending prior to the date of
determination), 
 and decreased by, as of the date of determination, the estimated discounted future net revenues from

 (C) estimated proved oil and gas reserves produced or disposed of since such year end, and 

  
 -2-

 (D) estimated oil and gas reserves attributable to downward revisions of
estimates of proved oil and gas reserves since such year end due to changes in geological conditions or other factors which would, in accordance with standard industry practice, cause such revisions, in each case calculated on a pre-tax basis and
substantially in accordance with SEC guidelines (utilizing the prices for the fiscal quarter ending prior to the date of determination), 
 provided, however, that in the case of each of the determinations made pursuant to clauses (A) through (D), such increases and decreases shall be as estimated by the Issuer’s petroleum
engineers; 
 (ii) the capitalized costs that are attributable to Oil and Gas Properties of such Person and its
Restricted Subsidiaries to which no proved oil and gas reserves are attributable, based on such Person’s books and records as of a date no earlier than the date of such Person’s latest available annual or quarterly financial statements;

 (iii) the Net Working Capital of such Person on a date no earlier than the date of such Person’s latest
annual or quarterly financial statements; and 
 (iv) the greater of 

(A) the net book value of other tangible assets of such Person and its Restricted Subsidiaries, as of a date no earlier
than the date of such Person’s latest annual or quarterly financial statement, and 
 (B) the appraised
value, as estimated by independent appraisers, of other tangible assets of such Person and its Restricted Subsidiaries, as of a date no earlier than the date of such Person’s latest audited financial statements; 

minus 
 (b) the sum of: 
 (i) Minority Interests; 

(ii) any net gas balancing liabilities of such Person and its Restricted Subsidiaries reflected in such Person’s
latest audited balance sheet; 
 (iii) to the extent included in (a)(i) above, the discounted future net
revenues, calculated in accordance with SEC guidelines (utilizing the prices 

  
 -3-

 
utilized in such Person’s year end reserve report), attributable to reserves which are required to be delivered to third parties to fully satisfy the obligations of the Issuer and its
Restricted Subsidiaries with respect to Volumetric Production Payments (determined, if applicable, using the schedules specified with respect thereto); and 
 (iv) the discounted future net revenues, calculated in accordance with SEC guidelines, attributable to reserves subject to Dollar-Denominated Production Payments which, based on the estimates of
production and price assumptions included in determining the discounted future net revenues specified in (a)(i) above, would be necessary to fully satisfy the payment obligations of such Person and its Subsidiaries with respect to Dollar-Denominated
Production Payments (determined, if applicable, using the schedules specified with respect thereto). 
 If the Issuer changes
its method of accounting from the full cost method of accounting to the successful efforts or a similar method, “Adjusted Consolidated Net Tangible Assets” will continue to be calculated as if the Issuer were still using the full cost
method of accounting. 
 “Affiliate” of any specified Person means any other Person, directly or indirectly,
controlling or controlled by or under direct or indirect common control with such specified Person. For the purposes of this definition, “control” when used with respect to any Person means the power to direct the management and policies
of such Person, directly or indirectly, whether through the ownership of voting securities, by contract or otherwise; and the terms “controlling” and “controlled” have meanings correlative to the foregoing. 

“Affiliate Transaction” has the meaning provided in Section 4.11. 

“Agent” means any Registrar, Paying Agent or co-Registrar. 

“Applicable Premium” means, with respect to any Note on any applicable redemption date, the greater of: 

(1) 1.0% of the principal amount of such Note; and 

(2) the excess, if any, of: 
 (a) the sum of the present value at such redemption date of (i) the redemption price of such Note at February 15, 2015 (such redemption price being set forth in the table appearing in
Section 3.3) plus (ii) all required interest payments (excluding accrued and unpaid interest as of such redemption date) due on such Note through February 15, 2015, discounted back to the redemption

  
 -4-

 
date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points; over

calculated after giving effect on a pro forma basis to such Indebtedness and the use of proceeds thereof as if such Indebtedness had been Incurred on the first day of such period and such proceeds had been applied as of such date (except that in
making such computation, the amount of Indebtedness under any revolving credit facility outstanding on the date of such calculation will be deemed to be (i) the average daily balance of such Indebtedness during such four fiscal quarters or such

Ratio involves a discharge of Indebtedness (in each case other than Indebtedness Incurred under any revolving credit facility unless such Indebtedness has been permanently repaid and the related commitment terminated), Consolidated EBITDA and
Consolidated Interest Expense for such period will be calculated after giving effect on a pro forma basis to such discharge of such Indebtedness as if such discharge had occurred on the first day of such period; 

(2) if, since the beginning of such period, the Issuer or any Restricted Subsidiary will have made any Asset Disposition
or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is such an Asset Disposition, the Consolidated EBITDA for such period will be reduced by an amount equal to the Consolidated EBITDA (if positive) directly
attributable to the assets that are the subject of such Asset Disposition for such period or increased by an amount equal to the Consolidated EBITDA (if negative) directly attributable thereto for such period and Consolidated Interest Expense for
such period shall be reduced by an amount equal to the Consolidated Interest Expense directly attributable to any Indebtedness of the Issuer or any Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with respect to the

(3) if since the beginning of such period the Issuer or any Restricted Subsidiary (by merger or otherwise) will have made

had occurred on the first day of such period; and 
 (4) if since the beginning of such period any Person (that
subsequently became a Restricted Subsidiary or was merged with or into the Issuer or any Restricted 

  
 -11-

 
Subsidiary since the beginning of such period) made any Asset Disposition or any Investment or acquisition of assets that would have required an adjustment pursuant to clause (2) or
(3) above if made by the Issuer or a Restricted Subsidiary during such period, Consolidated EBITDA and Consolidated Interest Expense for such period will be calculated after giving pro forma effect thereto as if such Asset Disposition or
Investment or acquisition of assets had occurred on the first day of such period. 
 For purposes of this definition, whenever
pro forma effect is to be given to any calculation under this definition, the pro forma calculations will be determined in good faith by a responsible financial or accounting officer of the Issuer (including pro forma expense and cost reductions
calculated on a basis consistent with Regulation S-X under the Securities Act). If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest expense on such Indebtedness will be calculated as if the average
rate in effect from the beginning of such period to the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness, but if the remaining term of such
Interest Rate Agreement is less than 12 months, then such Interest Rate Agreement shall only be taken into account for that portion of the period equal to the remaining term thereof). If any Indebtedness that is being given pro forma effect bears an
interest rate at the option of the Issuer, the interest rate shall be calculated by applying such optional rate chosen by the Issuer. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or
similar rate, a eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Issuer may designate.

 (6) consolidated exploration expense of the Issuer and its Restricted Subsidiaries, 

if applicable for such period; and less, to the extent included in calculating such Consolidated Net Income and in excess of any costs or expenses

Volumetric Production Payments, (y) amounts recorded in accordance with GAAP as repayments of principal and interest pursuant to Dollar-Denominated Production Payments and (z) other non-cash gains (excluding any non-cash gain to the extent
it represents the reversal of an accrual or reserve for a potential cash item that reduced Consolidated EBITDA in any prior period).

orders, statutes, rules and governmental regulations applicable to that Restricted Subsidiary or its shareholders.

“Consolidated Interest Expense” means, for any period, the total consolidated interest expense of the Issuer and its

Contemplation of Convertible Debt Issuance or Other Financing,” now codified under FASB ASC Topic 470 “Debt;”

benefits shall be credited to reduce Consolidated Interest Expense unless, pursuant to GAAP, such net benefits are otherwise reflected in Consolidated Net Income; 

(7) the consolidated interest expense of such Person and its Restricted Subsidiaries that was capitalized during such
period; 
 (8) all dividends paid or payable in cash, Cash Equivalents or Indebtedness or accrued during such

LLC during such period to the Issuer or a Restricted Subsidiary as a dividend or other distribution (subject, in the case of a dividend or other distribution to a Restricted Subsidiary, to the limitations contained in clause (2) below) shall be

facsimile signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 
 The Trustee shall authenticate (i) Notes for original issue on the Issue Date in the aggregate principal amount not to exceed $200,000,000, (ii) subject to Section 4.12, Additional
Notes and (iii) Exchange Notes, in each case, upon a written order of the Issuer in the form of an Officer’s Certificate. Each such written order shall specify the amount of Notes to be authenticated and the date on which the Notes are to
be authenticated, whether the Notes are to be Notes or Additional Notes and whether the Notes are to be issued as Definitive Notes or Global Notes or such other information as the Trustee may reasonably request. Any Additional Notes shall be part of
the same issue as the Notes being issued on the Issue Date and will vote on all matters as one class with the Notes being issued on the Issue Date, including, without limitation, waivers, amendments, redemptions, Change of Control Offers and Asset
Disposition Offers. For the purposes of this Indenture, except for Section 4.12, references to the Notes include Additional Notes, if any. In addition, with respect to authentication pursuant to clause (ii) of the first sentence of
this paragraph, the first such written order from the Issuer shall be accompanied by an Opinion of Counsel of the Issuer in a form reasonably satisfactory to the Trustee stating that the issuance of the Additional Notes does not give rise to an
Event of Default, complies with this Indenture and has been duly authorized by the Issuer. 
 The Trustee may appoint an
authenticating agent (the “Authenticating Agent”) reasonably acceptable to the Issuer to authenticate Notes. Unless otherwise provided in the appointment, an Authenticating Agent may authenticate Notes whenever the Trustee may do
so. Each reference in this Indenture to authentication by the Trustee includes authentication by such Authenticating Agent. An Authenticating Agent has the same rights as an Agent to deal with the Issuer or with any Affiliate of the Issuer.

 The Notes shall be issuable in fully registered form only, without coupons, in denominations of at least $2,000 and any
integral multiple of $1,000 in excess thereof. 
 SECTION 2.3. Registrar and Paying Agent.

 The Issuer shall maintain an office or agency where (a) Notes may be presented or surrendered for registration
of transfer or for exchange (“Registrar”), (b) Notes may be presented or surrendered for payment (“Paying Agent”) and (c) notices and demands to or upon the Issuer in respect of the Notes and this
Indenture may be served. The Registrar shall keep a register of the Notes and of their transfer and exchange. The Issuer, upon prior written notice to the Trustee, may have one or more co-Registrars and one or more additional paying agents
reasonably acceptable to the Trustee. The term “Paying Agent” includes any additional Paying Agent. The Issuer may act as Paying Agent, except that, for the purposes of payments on the Notes pursuant to Sections 4.15 and
4.16, neither the Issuer nor any Affiliate of the Issuer may act as Paying Agent. 

  
 -48-

 The Issuer shall enter into an appropriate agency agreement with any Agent not a party to
this Indenture, which agreement shall incorporate the provisions of the TIA and implement the provisions of this Indenture that relate to such Agent. The Issuer shall notify the Trustee, in advance, of the name and address of any such Agent. If the
Issuer fails to maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such. 

The Issuer initially appoints the Trustee as Registrar, Paying Agent and agent for service of demands and notices in connection with the
Notes, until such time as the Trustee has resigned or a successor has been appointed. Any of the Registrar, the Paying Agent or any other agent may resign upon 30 days’ prior written notice to the Issuer. 

SECTION 2.4. Paying Agent To Hold Assets in Trust. 

The Issuer shall require each Paying Agent other than the Trustee to agree in writing that such Paying Agent shall hold in trust for the
benefit of the Holders or the Trustee all assets held by the Paying Agent for the payment of principal of, premium or Liquidated Damages, if any, or interest on, the Notes (whether such assets have been distributed to it by the Issuer or any other
obligor on the Notes), and the Issuer and the Paying Agent shall notify the Trustee of any Default by the Issuer (or any other obligor on the Notes) in making any such payment. The Issuer at any time may require a Paying Agent to distribute all
assets held by it to the Trustee and account for any assets disbursed and the Trustee may at any time during the continuance of any payment Default, upon written request to a Paying Agent, require such Paying Agent to distribute all assets held by
it to the Trustee and to account for any assets distributed. If the Issuer acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all assets held by it as Paying Agent. Upon distribution to the
Trustee of all assets that shall have been delivered by the Issuer to the Paying Agent, the Paying Agent (if other than the Issuer) shall have no further liability for such assets. 

SECTION 2.5. Holder Lists. 
 The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of the Holders and shall otherwise comply with TIA
§ 312(a). If the Trustee is not the Registrar, the Issuer shall furnish or cause the Registrar to furnish to the Trustee before each Record Date and at such other times as the Trustee may request in writing a list as of such date and in
such form as the Trustee may reasonably require of the names and addresses of the Holders, which list may be conclusively relied upon by the Trustee.

 SECTION 2.6. Transfer and Exchange. 

(a) Transfer and Exchange of Global Notes. Except as otherwise set forth in this Section 2.6, a Global Note may be
transferred, in whole and not in part, only to another nominee of the Depository or to a successor Depository or a nominee of such successor Depository. A beneficial interest in a Global Note may not be exchanged for a Definitive Note unless
(i) the Depository (x) notifies the Issuer that it is unwilling or unable to continue as Depository for such Global Note or (y) has ceased to be a clearing agency registered under the Exchange Act and, in either case, a successor
Depository is not appointed by the Issuer within 120 days or (ii) there shall have occurred and be continuing a Default with respect to the Notes. Upon the occurrence of any of the preceding events in clause (i) or (ii) above,
Definitive Notes delivered in exchange for any Global Note or beneficial interests therein will be registered in the names, and issued in any approved denominations, requested by or on behalf of the Depository (in accordance with its customary
procedures). Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.7 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 2.6 or Section 2.7 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note, except for Definitive Notes issued subsequent to any of the preceding events
in clause (i) or (ii) above and pursuant to Section 2.6(c) hereof. A Global Note may not be exchanged for another Note other than as provided in this Section 2.6(a); provided, however, beneficial
interests in a Global Note may be transferred and exchanged as provided in Section 2.6(b), (c) or (f) hereof. 
 (b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes shall be effected through the Depository, in accordance
with the provisions of this Indenture and the Applicable Procedures. Beneficial interests in the Restricted Global Notes shall be subject to restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act.
Transfers of beneficial interests in the Global Notes also shall require compliance with either subparagraph (i) or (ii) below, as applicable, as well as one or more of the other following subparagraphs, as applicable: 

(i) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Restricted Global Note may be

prior to the expiration of the Restricted Period, transfers of beneficial interests in the Regulation S Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person (other than an Initial Purchaser). Beneficial
interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the
Registrar to effect the transfers described in this Section 2.6(b)(i).

connection with all transfers and exchanges of beneficial interests that are not subject to Section 2.6(b)(i) hereof, the transferor of such beneficial interest must deliver to the Registrar either (A) (1) a written order from
a Participant or an Indirect Participant given to the Depository in accordance with the Applicable Procedures directing the Depository to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the

provided that in no event shall Definitive Notes be issued upon the transfer or exchange of beneficial interests in the Regulation S Global Note prior to (A) the expiration of the Restricted Period and (B) the receipt by the
Registrar of any certificates required pursuant to Rule 903. Upon consummation of a Registered Exchange Offer by the Issuer in accordance with Section 2.06(f) hereof, the requirements of this Section 2.06(b)(ii) shall be
deemed to have been satisfied upon receipt by the Registrar of the instructions contained in the Letter of Transmittal delivered by the Holder of such beneficial interests in the Restricted Global Notes. Upon satisfaction of all of the requirements

Section 2.6(f) hereof.

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 shall be increased
accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depository at the direction of the Trustee to reflect such increase. 
 (h) General Provisions Relating to Transfers and Exchanges. 
 (i) To permit
registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.2 hereof or at the
Registrar’s request. 
 (ii) No service charge shall 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 Issuer 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 2.7, 2.10, 3.7, 4.15, 4.16 and 9.5 hereof). 

(iii) Neither the Registrar nor the Issuer shall be required to register the transfer of or exchange any Note selected for redemption in
whole or in part, except the unredeemed portion of any Note being redeemed in part. 
 (iv) All Global Notes and Definitive
Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Issuer, 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. 

  
 -61-

 (v) The Issuer shall not 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 3.2 hereof and ending at the close of business on the day of selection, (B) to
register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part or (C) to register the transfer of or to exchange a Note between a Record Date and
the next succeeding Interest Payment Date. 
 (vi) Prior to due presentment for the registration of a transfer of any Note, the
Trustee, any Agent and the Issuer 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 (and premium, if any), Liquidated Damages, if any, and
interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Issuer shall be affected by notice to the contrary. 
 (vii) Upon surrender for registration of transfer of any Note at the office or agency of the Issuer designated pursuant to Section 4.2 hereof, the Issuer shall execute, and the Trustee shall
authenticate and mail, in the name of the designated transferee or transferees, one or more replacement Notes of any authorized denomination or denominations of a like aggregate principal amount. 

(viii) At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination or denominations of a like
aggregate principal amount upon surrender of the Notes to be exchanged at such office or agency. Whenever any Global Notes or Definitive Notes are so surrendered for exchange, the Issuer shall execute, and the Trustee shall authenticate and mail,
the replacement Global Notes and Definitive Notes which the Holder making the exchange is entitled to in accordance with the provisions of Section 2.2 hereof. 
 (ix) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.6 to effect a registration of transfer or exchange may be
submitted by facsimile. 
 SECTION 2.7. Replacement Notes. 

If a mutilated Note is surrendered to the Trustee or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully
taken, the Issuer shall issue and the Trustee shall authenticate a replacement Note and the Subsidiary Guarantors shall execute a Subsidiary Guarantee thereon if the Trustee’s requirements are met. If required by the Trustee or the Issuer, such
Holder must provide an indemnity bond or other indemnity of reasonable tenor, sufficient in the reasonable judgment of the Issuer, the Subsidiary Guarantors and the Trustee, to protect the Issuer, the Subsidiary Guarantors, the Trustee or any Agent
from 

  
 -62-

 
any loss which any of them may suffer if a Note is replaced. Every replacement Note shall constitute an additional obligation of the Issuer and the Subsidiary Guarantors. 

SECTION 2.8. Outstanding Notes. 

Notes outstanding at any time are all the Notes that have been authenticated by the Trustee except those canceled by it, those delivered
to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof and those described in this Section as not outstanding. Subject to the provisions of Section 2.9,
a Note does not cease to be outstanding because the Issuer or any of its Affiliates holds the Note. 
 If a Note is replaced
pursuant to Section 2.7 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser for value. A
mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.7. 
 If on a Redemption Date or the Maturity Date the Paying Agent (other than the Issuer, a Subsidiary or an Affiliate of any thereof) holds U.S. Legal Tender or U.S. Government Obligations sufficient to pay
all of the principal, premium, if any, and interest due on the Notes payable on that date and is not prohibited from paying such money to the Holders thereof pursuant to the terms of this Indenture, then on and after that date such Notes shall be
deemed not to be outstanding and interest on them shall cease to accrue. 
 SECTION 2.9. Treasury
Notes. 
 In determining whether the Holders of the required principal amount of Notes have concurred in any
direction, waiver, consent or notice, Notes owned by the Issuer or any Subsidiary Guarantor or an Affiliate of the Issuer or any Subsidiary Guarantor shall be considered as though they are not outstanding, except that for the purposes of determining
whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which a Trust Officer of the Trustee actually knows are so owned shall be so considered. The Issuer shall notify the Trustee, in writing, when, to
its knowledge, any of its Affiliates repurchase or otherwise acquire Notes, of the aggregate principal amount of such Notes so repurchased or otherwise acquired and such other information as the Trustee may reasonably request and the Trustee shall
be entitled to rely thereon. 
 SECTION 2.10. Temporary Notes. 

Until definitive Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes upon receipt of
a written order of the Issuer in the form of an Officer’s Certificate. The Officer’s Certificate shall specify the amount of temporary 

  
 -63-

 
Notes to be authenticated and the date on which the temporary Notes are to be authenticated. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that
the Issuer considers appropriate for temporary Notes and so indicate in the Officer’s Certificate. Without unreasonable delay, the Issuer shall prepare, the Trustee shall authenticate and the Subsidiary Guarantors shall execute Subsidiary
Guarantees on, upon receipt of a written order of the Issuer pursuant to Section 2.2, definitive Notes in exchange for temporary Notes. 
 SECTION 2.11. Cancellation. 
 The Issuer at any
time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar
or the Paying Agent, and no one else, shall cancel and, at the written direction of the Issuer, shall dispose, in its customary manner, of all Notes surrendered for transfer, exchange, payment or cancellation. The Trustee shall maintain a record of
all canceled Notes. Subject to Section 2.7, the Issuer may not issue new Notes to replace Notes that they have paid or delivered to the Trustee for cancellation. If either Issuer shall acquire any of the Notes, such acquisition shall not
operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.11. 

SECTION 2.12. Defaulted Interest. 

The Issuer will pay interest on overdue principal from time to time on demand at a rate of two percentage points per annum in excess of
the rate of interest then borne by the Notes. The Issuer shall, to the extent lawful, pay interest on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at a rate of two percentage points
per annum in excess of the rate of interest then borne by the Notes. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months, and, in the case of a partial month, the actual number of days elapsed. 

If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest, plus (to the extent lawful) any
interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, which special record date shall be the fifteenth day next preceding the date fixed by the Issuer for the payment of defaulted interest or
the next succeeding Business Day if such date is not a Business Day. The Issuer shall 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 (a “Default
Interest Payment Date”), and at the same time the Issuer shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest or shall make arrangements satisfactory to
the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled 

  
 -64-

 
to such defaulted interest as provided in this Section; provided, however, that in no event shall the Issuer deposit monies proposed to be paid in respect of defaulted interest
later than 11:00 a.m. New York City time of the proposed Default Interest Payment Date. At least 15 days before the subsequent special record date, the Issuer shall mail (or cause to be mailed) to each Holder, as of a recent date selected by the
Issuer, with a copy to the Trustee, a notice that states the subsequent special record date, the payment date and the amount of defaulted interest, and interest payable on such defaulted interest, if any, to be paid. Notwithstanding the foregoing,
(a) any interest which is paid prior to the expiration of the 30-day period set forth in Section 6.1(1) shall be paid to Holders as of the regular record date for the Interest Payment Date for which interest has not been paid, and
(b) the Issuer may make payment of any defaulted interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange.

 SECTION 2.13. CUSIP Number. 
 The Issuer in issuing the Notes may use a “CUSIP” number, and, if so, the Trustee shall use the CUSIP number in notices of redemption or exchange as a convenience to Holders; provided,
however, that no representation is hereby deemed to be made by the Trustee as to the correctness or accuracy of the CUSIP number printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers
printed on the Notes. The Issuer shall promptly notify the Trustee of any change in the CUSIP number. 
 SECTION 2.14.
Deposit of Monies. 
 Prior to 11:00 a.m. New York City time on each Interest Payment Date, Maturity Date,
Redemption Date, Change of Control Payment Date and Asset Disposition Purchase Date, the Issuer shall have deposited with the Paying Agent in immediately available funds money sufficient to make cash payments, if any, due on such Interest Payment
Date, Maturity Date, Redemption Date, Change of Control Payment Date and Asset Disposition Purchase Date, as the case may be, in a timely manner which permits the Paying Agent to remit payment to the Holders on such Interest Payment Date, Maturity
Date, Redemption Date, Change of Control Payment Date and Asset Disposition Purchase Date, as the case may be. 
 SECTION 2.15.

 ARTICLE III. 

REDEMPTION 

SECTION 3.1. Notices to Trustee. 
 If the Issuer elects to redeem Notes pursuant to Paragraph 5 of the Notes, they shall notify the Trustee and the Paying Agent in writing of the Redemption Date and the principal amount of the Notes
to be redeemed. 
 The Issuer shall give each notice provided for in this Section 3.1 60 days before the
Redemption Date (unless a shorter notice period shall be satisfactory to the Trustee, as evidenced in a writing signed on behalf of the Trustee), together with an Officer’s Certificate stating that such redemption shall comply with the
conditions contained herein and in the Notes. 
 SECTION 3.2. Selection of Notes To Be Redeemed.

 If less than all of the Notes are to be redeemed at any time, selection of such Notes, or portions thereof, for redemption

least 30 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of
the principal amount thereof to be redeemed. A new Note in a principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note. On and after the applicable Redemption

Date, the Issuer shall mail or cause to be mailed a notice of redemption by first-class mail to each Holder of Notes to be redeemed at its registered address, with a copy to the Trustee and any Paying Agent. At the Issuer’s request, the Trustee
shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense. The Issuer shall provide such notices of redemption to the Trustee at least three Business Days before the intended mailing date. 

Each notice of redemption shall identify (including the CUSIP number) the Notes to be redeemed and shall state: 

(1) the Redemption Date; 
 (2) the Redemption Price and the amount of unpaid accrued interest, if any, to be paid; 
 (3) the name and address of the Paying Agent; 
 (4) the
subparagraph of the Notes pursuant to which such redemption is being made; 
 (5) that Notes called for
redemption must be surrendered to the Paying Agent to collect the Redemption Price plus unpaid accrued interest, if any; 
 (6) that, unless the Issuer defaults in making the redemption payment, interest on Notes or applicable portions thereof called for redemption ceases to accrue on and after the Redemption Date, and the

other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the purchase of Notes. 
 SECTION 3.5. Effect of Notice of Redemption. 
 Once notice of
redemption is mailed in accordance with Section 3.4, such notice of redemption shall be irrevocable and Notes called for redemption shall become due and payable on the Redemption Date and at the Redemption Price plus unpaid accrued
interest and Liquidated Damages, if any, as of such date, if any. Upon surrender to the Trustee or Paying Agent, such Notes called for redemption shall be paid at the Redemption Price plus unpaid accrued interest and Liquidated Damages thereon to
the Redemption Date, but installments of interest, the maturity of which is on or prior to the Redemption Date, shall be payable to Holders of record at the close of business on the relevant Record Dates referred to in the Notes. Interest shall
accrue on or after the Redemption Date and shall be payable only if the Issuer defaults in payment of the Redemption Price. 

SECTION 3.6. Deposit of Redemption Price. 
 On or before the Redemption Date and in accordance with Section 2.14, the Issuer shall deposit with the Paying Agent U.S. Legal Tender sufficient to pay the Redemption Price plus unpaid
accrued interest and Liquidated Damages, if any, of all Notes to be redeemed on that date. The Paying Agent shall promptly return to the Issuer any U.S. Legal Tender so deposited which is not required for that purpose, except with respect to monies
owed as obligations to the Trustee pursuant to Article VII. 
 Unless the Issuer fails to comply with the preceding paragraph
and defaults in the payment of such Redemption Price plus unpaid accrued interest, if any, interest on the Notes to be redeemed will cease to accrue on and after the applicable Redemption Date, whether or not such Notes are presented for payment.

 SECTION 3.7. Notes Redeemed in Part.

improvements thereto and actively conduct and carry on its business; provided, however, that nothing in this Section 4.5 shall prevent the Issuer or any of the Restricted Subsidiaries from discontinuing the operation and

appropriate self-insurance) against loss or damage of the kinds that, in the good faith judgment of the Issuer, are adequate and appropriate for the conduct of the business of the Issuer and its Restricted Subsidiaries in a prudent manner, with
reputable insurers or with the government of the United States of America, Canada or an agency or instrumentality thereof, in such amounts, with such deductibles, and by such methods as shall be customary, in the good faith judgment of the Issuer,

Indenture and the form of the Notes as they relate to accounting matters, and (B) whether, in connection with their audit examination, any Default or Event of Default has come to their attention and if such a Default or Event of Default has
come to their attention, specifying the nature and period of existence thereof; provided, however, that, without any restriction as to the scope of the audit examination, such independent certified public accountants shall not be
liable by reason of any failure to obtain knowledge of any such Default or Event of Default that would not be disclosed in the course of an audit examination conducted in accordance with generally accepted auditing standards.

 SECTION 4.7. Compliance with Laws. 
 The Issuer shall comply,
and shall cause each of its Restricted Subsidiaries to comply, with all applicable statutes, rules, regulations, orders and restrictions of the United States of America, all states and municipalities thereof, and of any governmental department,
commission, board, regulatory authority, bureau, agency and instrumentality of the foregoing, in respect of the conduct of its respective businesses and the ownership of its respective properties, except for such noncompliances as could not singly
or in the aggregate reasonably be expected to have a material adverse effect on the financial condition or results of operations of the Issuer and the Restricted Subsidiaries taken as a whole.

(a) Whether or not the Issuer is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, to the extent not
prohibited by the Exchange Act, the Issuer will file with the SEC, and make available to the Trustee and the registered Holders without cost to any Holder, the annual reports and the information, documents and other reports (or copies of such
portions of any of the foregoing as the SEC may by rules and regulations prescribe) that are specified in Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation within the time periods specified therein with respect to a
non-accelerated filer. In the event that the Issuer is not permitted to file such reports, documents and information with the SEC pursuant to the Exchange Act, the Issuer will nevertheless make available such Exchange Act information to the Trustee
and the Holders without cost to any Holder as if the Issuer were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act within the time periods specified therein with respect to a non-accelerated filer. 

(b) If the Issuer has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial
information required by the preceding paragraph shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes to the financial statements and in Management’s Discussion and Analysis of
Results of Operations and Financial Condition, of the financial condition and results of operations of the Issuer and its Restricted Subsidiaries. 
 (c) In addition, the Issuer and the Subsidiary Guarantors have agreed that they will make available to the Holders and to prospective investors, upon the request of such Holders, the information required
to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Notes are not freely transferable under the Securities Act to the extent not satisfied by the foregoing. For purposes of this Section 4.8, the Issuer and
the Subsidiary Guarantors will be deemed to have furnished the reports to the Trustee and the Holders of Notes as required by this Section 4.8 if the Issuer has filed such reports with the SEC via the EDGAR filing system and such reports
are publicly available. 
 (d) Notwithstanding the foregoing, such requirements shall be deemed satisfied prior to the
commencement of the Registered Exchange Offer or the effectiveness of the Shelf Registration Statement by the filing with the SEC of the Exchange Offer Registration Statement or Shelf Registration Statement, and any amendments thereto, with such
financial information that satisfies Regulation S-X of the Securities Act within the time period specified by the Registration Rights Agreement. 
 SECTION 4.9. Waiver of Stay, Extension or Usury Laws. 
 The
Issuer and each of the Subsidiary Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever 

  
 -76-

 
claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the Issuer from paying all or any portion of the principal of or
interest or Liquidated Damages, if any, on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do
so) the Issuer and each of the Subsidiary Guarantors hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer
and permit the execution of every such power as though no such law had been enacted.

(b) the Issuer is not able to Incur an additional $1.00 of Indebtedness pursuant to the first paragraph of
Section 4.12 after giving effect, on a pro forma basis, to such Restricted Payment; or 
 (c) the
aggregate amount of such Restricted Payment and all other Restricted Payments declared or made subsequent to the Issue Date would exceed the sum of: 
 (i) 50% of Consolidated Net Income for the period (treated as one accounting period) from January 1, 2011 to the end of the most recent fiscal quarter ending prior to the date of such Restricted
Payment for which internal financial statements are in existence (or, in case such Consolidated Net Income is a deficit, minus 100% of such deficit); 
 (ii) 100% of the aggregate Net Cash Proceeds, and the fair market value (as determined by the Issuer’s Board of Directors in good faith) of property or securities other than cash (including Capital

prior to the date of determination)); 
 (iii) the amount by which Indebtedness of the Issuer or its Restricted
Subsidiaries is reduced on the Issuer’s balance sheet upon the conversion or exchange (other than by a Subsidiary of the Issuer) subsequent to the Issue Date of any Indebtedness of the Issuer or its Restricted Subsidiaries convertible or
exchangeable for Capital Stock (other than Disqualified Stock) of the Issuer (less the amount of any cash, or the fair market value of any other property (other than such Capital Stock), distributed by the Issuer upon such conversion or exchange and
excluding the Net Cash Proceeds from the conversion or exchange financed, directly or indirectly, using funds borrowed from the Issuer or any Subsidiary), together with the net proceeds, if any, received by the Issuer or any of its Restricted
Subsidiaries upon such conversion or exchange; and 
 (iv) the amount equal to the aggregate net reduction in
Restricted Investments made by the Issuer or any of its Restricted Subsidiaries in any Person resulting from:

provided in the definition of “Investment”) not to exceed, in the case of any Unrestricted Subsidiary, the amount of Investments previously made by the Issuer or any Restricted Subsidiary in such Unrestricted Subsidiary, which amount in
each case under this clause (iv) was included in the calculation of the amount of Restricted Payments; provided, however, that no amount will be included under this clause (iv) to the extent it is already included in Consolidated

Unrestricted Subsidiary, all outstanding Investments by the Issuer and its Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated will be deemed to be Restricted Payments in an amount determined as set forth in the
last sentence of the definition of “Investment.” Such designation will be permitted only if a Restricted Payment in such amount would be permitted at such time, whether pursuant to the first paragraph of this Section 4.10 or
under clause (13) of the second paragraph of this Section 4.10, or pursuant to the definition of “Permitted Investments,” and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. Unrestricted

with or for the benefit of any Affiliate of the Issuer (an “Affiliate Transaction”) unless: 

  
 -83-

 (1) the terms of such Affiliate Transaction are no less favorable to the
Issuer or such Restricted Subsidiary, as the case may be, than those that could be obtained in a comparable transaction at the time of such transaction in arm’s-length dealings with a Person who is not such an Affiliate; 

(2) if such Affiliate Transaction involves an aggregate consideration in excess of $10.0 million, the terms of such
transaction have been approved by a majority of the members of the Board of Directors of the Issuer and by a majority of the members of such Board of Directors having no personal stake in such transaction, if any (and such majority or majorities, as
the case may be, determines that such Affiliate Transaction satisfies the criteria in clause (1) above); and 
 (3) if such Affiliate Transaction involves an aggregate consideration in excess of $20.0 million, the Board of Directors of the Issuer has received a written opinion from an independent investment
banking, accounting or appraisal firm of nationally recognized standing that such Affiliate Transaction is fair, from a financial standpoint, to the Issuer or such Restricted Subsidiary or is not materially less favorable than those that could
reasonably be expected to be obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate. 
 The preceding paragraph will not apply to: 
 (1) any Restricted
Payment permitted to be made pursuant to Section 4.10; 
 (2) any issuance of Capital Stock (other
than Disqualified Stock), or other payments, awards or grants in cash, Capital Stock (other than Disqualified Stock) or otherwise pursuant to, or the funding of, employment or severance agreements and other compensation arrangements, options to

issued by the Issuer or a Restricted Subsidiary for the benefit of the Issuer or a Restricted Subsidiary, as the case may be, in accordance with Section 4.12; 

  
 -84-

 (5) any transaction with a joint venture or similar entity which would
constitute an Affiliate Transaction solely because the Issuer or a Restricted Subsidiary owns, directly or indirectly, an equity interest in or otherwise controls such joint venture or similar entity; 

(6) the issuance or sale of any Capital Stock (other than Disqualified Stock) of the Issuer or the receipt by the Issuer
of any capital contribution from its shareholders; 
 (7) indemnities of officers, directors and employees of the
Issuer or any of its Restricted Subsidiaries permitted by bylaw or statutory provisions and any employment agreement or other employee compensation plan or arrangement entered into in the ordinary course of business by the Issuer or any of its
Restricted Subsidiaries;

obligations of the Issuer or any of its Restricted Subsidiaries under the terms of any agreement to which the Issuer or any of its Restricted Subsidiaries is a party as of or on the Issue Date, as these agreements may be amended, modified,
supplemented, extended or renewed from time to time; provided, however, that any future amendment, modification, supplement, extension or renewal entered into after the Issue Date will be permitted to the extent that its terms are not
materially more disadvantageous, taken as a whole, to the Holders of the Notes than the terms of the agreements in effect on the Issue Date; and 
 (10) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this
Indenture which are fair to the Issuer and its Restricted Subsidiaries, in the reasonable determination of the Board of Directors of the Issuer or the senior management thereof, or are on terms at least as favorable as might reasonably have been
obtained at such time from an unaffiliated party.

Preferred Stock. 
 The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, Incur any Indebtedness (including Acquired Indebtedness), and the Issuer will not permit any of its Restricted Subsidiaries to issue Preferred Stock; provided, however, that the Issuer may Incur Indebtedness and any of the
Subsidiary Guarantors may Incur Indebtedness and issue Preferred Stock if on the date thereof: 

  
 -85-

 (1) the Consolidated Coverage Ratio for the Issuer and its Restricted
Subsidiaries is at least 2.50 to 1.00, determined on a pro forma basis (including a pro forma application of proceeds); and

case may be, Incurred in accordance with the provisions of this Indenture; provided that in the event such Indebtedness that is being Guaranteed is a Subordinated Obligation or a Guarantor Subordinated Obligation, then the related Guarantee

(3) Indebtedness of the Issuer owing to and held by any Restricted Subsidiary or Indebtedness of a Restricted Subsidiary
owing to and held by the Issuer or any Restricted Subsidiary; provided, however, that (i) any subsequent issuance or transfer of Capital Stock or any other event which results in any such Indebtedness being held by a Person other than
the Issuer or a Restricted Subsidiary of the Issuer and (ii) any sale or other transfer of any such Indebtedness to a Person other than the Issuer or a Restricted Subsidiary of the Issuer shall be deemed, in each case, to constitute an
Incurrence of such Indebtedness by the Issuer or such Restricted Subsidiary, as the case may be; 
 (4)
Indebtedness represented by (a) the Notes issued on the Issue Date, and the related exchange notes issued in a registered exchange offer (or shelf registration) pursuant to the Registration Rights Agreement, and all Subsidiary Guarantees,

funds utilized to consummate the transaction or series of related transactions pursuant to which such Person became a Restricted Subsidiary or was otherwise acquired by or was merged into the Issuer or a Restricted Subsidiary or (b) otherwise
in connection with, or in contemplation of, such acquisition); provided, however, that at the time such Person becomes a Restricted Subsidiary or is acquired by or was merged into the Issuer or a Restricted Subsidiary, the Issuer would have
been able to Incur $1.00 of additional Indebtedness pursuant to the first paragraph of this Section 4.12 after giving effect to the Incurrence of such Indebtedness pursuant to this clause (5); 

(6) the Incurrence by the Issuer or any Restricted Subsidiary of Indebtedness represented by Capitalized Lease

the Issuer or such Restricted Subsidiary, and Refinancing Indebtedness Incurred to refinance any Indebtedness Incurred pursuant to this clause (6) in an aggregate outstanding principal amount which, when taken together with the principal amount

Incurrence of such Indebtedness after giving effect to the application of the proceeds therefrom; 
 (7)
Indebtedness Incurred in respect of (a) self-insurance obligations, bid, appeal, reimbursement, performance, surety and similar bonds and completion Guarantees provided by the Issuer or a Restricted Subsidiary in the ordinary course of business
and any Guarantees or letters of credit functioning as or supporting any of the foregoing bonds or obligations and (b) obligations represented by letters of credit for the account of the Issuer or a Restricted Subsidiary in order to provide
security for workers’ compensation claims (in the case of clauses (a) and (b) other than for an obligation for money borrowed); and 

  
 -87-

 (8) in addition to the items referred to in clauses (1) through
(7) above, Indebtedness of the Issuer and the Subsidiary Guarantors in an aggregate outstanding principal amount which, when taken together with the principal amount of all other Indebtedness Incurred pursuant to this clause (8) and then
outstanding, will not exceed the greater of $10.0 million at any time outstanding and 2.5% of Adjusted Consolidated Net Tangible Assets determined as of the date of the Incurrence of such Indebtedness after giving effect to the application of the
proceeds therefrom. 
 For purposes of determining compliance with, and the outstanding principal amount of any particular
Indebtedness Incurred pursuant to and in compliance with, this Section 4.12: 
 (1) in the event an
item of that Indebtedness meets the criteria of more than one of the types of Indebtedness described in the first and second paragraphs of this Section 4.12, the Issuer, in its sole discretion, will classify such item of Indebtedness on
the date of Incurrence and, subject to clause (2) below may later reclassify such item of Indebtedness and only be required to include the amount and type of such Indebtedness in one of such clauses; 

(2) all Indebtedness outstanding on the date of this Indenture under the Senior Secured Credit Agreement shall be deemed
Incurred on the Issue Date under clause (1) of the second paragraph of this Section 4.12; 
 (3)
Guarantees of, or obligations in respect of letters of credit supporting, Indebtedness which is otherwise included in the determination of a particular amount of Indebtedness shall not be included; 

(4) if obligations in respect of letters of credit are Incurred pursuant to a Credit Facility and are being treated as
Incurred pursuant to clause (1) of the second paragraph above and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included; 

(5) the principal amount of any Disqualified Stock of the Issuer or a Restricted Subsidiary, or Preferred Stock of a
Restricted Subsidiary that is not a Subsidiary Guarantor, will be equal to the greater of the maximum mandatory redemption or repurchase price (not including, in either case, any redemption or repurchase premium) or the liquidation preference
thereof; 
 (6) Indebtedness permitted by this Section 4.12 need not be permitted solely by reference
to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this Section 4.12 permitting such Indebtedness; and 

  
 -88-

 (7) the amount of Indebtedness issued at a price that is less than the
principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP. 

Accrual of interest, accrual of dividends, the amortization of debt discount or the accretion of accreted value, the payment of interest
in the form of additional Indebtedness, the payment of dividends in the form of additional shares of Preferred Stock or Disqualified Stock and unrealized losses or charges in respect of Hedging Obligations (including those resulting from the
application of ASC Topic 815, “Derivatives and Hedging”) will not be deemed to be an Incurrence of Indebtedness for purposes of this Section 4.12. The amount of any Indebtedness outstanding as of any date shall be (i) the
accreted value thereof in the case of any Indebtedness issued with original issue discount and (ii) the principal amount or liquidation preference thereof, together with any interest thereon that is more than 30 days past due, in the case of
any other Indebtedness. 
 If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such
Subsidiary shall be deemed to be Incurred by a Restricted Subsidiary as of such date (and, if such Indebtedness is not permitted to be Incurred as of such date under this Section 4.12, the Issuer shall be in Default of this
Section 4.12). 
 For purposes of determining compliance with any U.S. dollar-denominated restriction on the
Incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred, in the
case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause
the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so
long as the principal amount of such Refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 4.12, the maximum amount of Indebtedness that
the Issuer may Incur pursuant to this Section 4.12 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Indebtedness Incurred to refinance other
Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on
the date of such refinancing. 

  
 -89-

 SECTION 4.13. Limitation on Restrictions on Distributions from Restricted
Subsidiaries. 
 The Issuer will not, and will not permit any Restricted Subsidiary to, create or otherwise cause or
permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary to: 
 (1) pay dividends or make any other distributions on its Capital Stock or pay any Indebtedness or other obligations owed to the Issuer or any Restricted Subsidiary (it being understood that the priority
of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on Common Stock shall not be deemed a restriction on the ability to make distributions on Capital Stock);

 (2) make any loans or advances to the Issuer or any Restricted Subsidiary (it being understood that the
subordination of loans or advances made to the Issuer or any Restricted Subsidiary to other Indebtedness Incurred by the Issuer or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or 

(3) sell, lease or transfer any of its property or assets to the Issuer or any Restricted Subsidiary. 

The preceding provisions will not prohibit: 
 (i) any encumbrance or restriction pursuant to or by reason of an agreement in effect at or entered into on the Issue Date, including, without limitation, this Indenture and the Senior Secured Credit
Agreement in effect on such date; 
 (ii) any encumbrance or restriction with respect to a Person pursuant to or
by reason of an agreement relating to any Capital Stock or Indebtedness Incurred by a Person on or before the date on which such Person was acquired by the Issuer or another Restricted Subsidiary (other than Capital Stock or Indebtedness Incurred as
consideration in, or to provide all or any portion of the funds utilized to consummate, the transaction or series of related transactions pursuant to which such Person was acquired by the Issuer or a Restricted Subsidiary or in contemplation of the
transaction) and outstanding on such date; provided, that any such encumbrance or restriction shall not extend to any assets or property of the Issuer or any other Restricted Subsidiary other than the assets and property so acquired;

 (iii) encumbrances and restrictions contained in contracts entered into in the ordinary course of business,
not relating to any Indebtedness, and that do not, individually or in the aggregate, detract from the value of, or from the ability of the Issuer 

  
 -90-

 
and the Restricted Subsidiaries to realize the value of, property or assets of the Issuer or any Restricted Subsidiary in any manner material to the Issuer or any Restricted Subsidiary;

 (iv) any encumbrance or restriction with respect to an Unrestricted Subsidiary pursuant to or by reason of an
agreement that the Unrestricted Subsidiary is a party to, entered into before the date on which such Unrestricted Subsidiary became a Restricted Subsidiary; provided, that such agreement was not entered into in anticipation of the
Unrestricted Subsidiary becoming a Restricted Subsidiary and any such encumbrance or restriction shall not extend to any assets or property of the Issuer or any other Restricted Subsidiary other than the assets and property so acquired; 

(v) any encumbrance or restriction with respect to a Restricted Subsidiary pursuant to an agreement effecting a refunding,
replacement or refinancing of Indebtedness Incurred pursuant to an agreement referred to in clauses (i), (ii), (iv) or (xi) of this paragraph or this clause (v) or contained in any amendment, restatement, modification, renewal,
supplemental, refunding, replacement or refinancing of an agreement referred to in clauses (i), (ii), (iv) or (xi) of this paragraph or this clause (v); provided, however, that the encumbrances and restrictions with respect to such
Restricted Subsidiary contained in any such agreement taken as a whole are no less favorable in any material respect to the Holders of the Notes than the encumbrances and restrictions contained in such agreements referred to in clauses (i), (ii),
(iv) or (xi) of this paragraph on the Issue Date or the date such Restricted Subsidiary became a Restricted Subsidiary or was merged into a Restricted Subsidiary, whichever is applicable; 

(vi) in the case of clause (3) of the first paragraph of this Section 4.13, any encumbrance or
restriction: 
 (a) that restricts in a customary manner the subletting, assignment or transfer of any property
or asset that is subject to a lease (including leases governing leasehold interests or farm-in agreements or farm-out agreements relating to leasehold interests in Oil and Gas Properties), license or similar contract, or the assignment or transfer
of any such lease (including leases governing leasehold interests or farm-in agreements or farm-out agreements relating to leasehold interests in Oil and Gas Properties), license or other contract; 

(b) contained in mortgages, pledges or other security agreements permitted under this Indenture securing Indebtedness of
the Issuer or a Restricted Subsidiary to the extent such encumbrances or restrictions restrict the transfer of the property subject to such mortgages, pledges or other security agreements; 

  
 -91-

 (c) pursuant to customary provisions restricting dispositions of real
property interests set forth in any reciprocal easement agreements of the Issuer or any Restricted Subsidiary; 

(d) restrictions on cash or other deposits imposed by customers under contracts entered into in the ordinary course of
business; or 
 (e) provisions with respect to the disposition or distribution of assets or property in
operating agreements, joint venture agreements, development agreements, area of mutual interest agreements and other agreements that are customary in the Oil and Gas Business and entered into in the ordinary course of business; 

(vii) (a) purchase money obligations for property acquired in the ordinary course of business and (b) Capitalized
Lease Obligations permitted under this Indenture, in each case, that impose encumbrances or restrictions of the nature described in clause (3) of the first paragraph of this Section 4.13 on the property so acquired; 

(viii) any encumbrance or restriction with respect to a Restricted Subsidiary (or any of its property or assets) imposed
pursuant to an agreement entered into for the direct or indirect sale or disposition of all or substantially all the Capital Stock or assets of such Restricted Subsidiary (or the property or assets that are subject to such restriction) pending the
closing of such sale or disposition; 
 (ix) any customary encumbrances or restrictions imposed pursuant to any
agreement of the type described in the definition of “Permitted Business Investment”; 
 (x)
encumbrances or restrictions arising or existing by reason of applicable law or any applicable rule, regulation or order; and 
 (xi) the Senior Secured Credit Agreement as in effect as of the Issue Date, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings
thereof, provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are not materially more restrictive in the aggregate with respect to such dividend and other
payment restrictions than those contained in the Senior Secured Credit Agreement as in effect on the Issue Date. 
 SECTION
4.14. Payments for Consents. 
 Neither the Issuer nor any of its Restricted Subsidiaries will, directly or
indirectly, pay or cause to be paid any consideration, whether by way of interest, fees or otherwise, 

  
 -92-

 
to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes, unless such consideration is offered to be paid or is
paid to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment. 
 SECTION 4.15. Change of Control. 
 If a Change of Control
occurs, unless the Issuer has previously or concurrently exercised its right to redeem all of the Notes pursuant to Section 3.3, each Holder will have the right to require the Issuer to repurchase all or any part (equal to $2,000 or an
integral multiple of $1,000 in excess thereof) of such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount of the Notes repurchased plus accrued and unpaid interest, if any, and Liquidated Damages, if any, to the
date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date). 
 Within 30 days following any Change of Control, unless the Issuer has previously or concurrently exercised its right to redeem all of the Notes pursuant to Section 3.3, the Issuer will mail a
notice (the “Change of Control Offer”) to each Holder, with a copy to the Trustee, stating: 

(1) that a Change of Control has occurred and that such Holder has the right to require the Issuer to purchase such
Holder’s Notes at a purchase price in cash equal to 101% of the principal amount of such Notes plus accrued and unpaid interest, if any, and Liquidated Damages, if any, to the date of purchase (subject to the right of Holders of record on a
record date to receive interest on the relevant interest payment date) (the “Change of Control Payment”); 
 (2) the repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date the Change of Control Offer is mailed) (the “Change of Control Payment Date”);

 (3) that any Note not properly tendered will remain outstanding and continue to accrue interest; 

(4) that unless the Issuer 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 on 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
such Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed, to the paying agent specified in the Change of Control Offer at the address specified in the

  
 -93-

 
Change of Control Offer 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 tendered Notes and their election to require the Issuer to purchase
such Notes, provided that the paying agent receives, not later than the close of business on the 30th day following the date of the Change of Control Offer, a telegram, telex, facsimile transmission or letter setting forth the name of the
Holder, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased; 

(7) that if the Issuer is redeeming less than all of the Notes, the Holders of the remaining Notes will be issued new
Notes and such new Notes will be equal in principal amount to the unpurchased portion of the Notes surrendered. The unpurchased portion of the Notes must be equal to $2,000 or an integral multiple of $1,000 in excess thereof; and 

(8) the procedures determined by the Issuer, consistent with this Indenture, that a Holder must follow in order to have
its Notes repurchased. 
 On the Change of Control Payment Date, the Issuer will, to the extent lawful: 

(1) accept for payment all Notes or portions of Notes (of at least $2,000 or an integral multiple of $1,000 in excess
thereof) properly tendered pursuant to the Change of Control Offer; 
 (2) deposit with the paying agent an
amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered and not properly withdrawn; and 
 (3) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased
by the Issuer. 
 The paying agent will promptly mail or wire transfer to each Holder properly tendered and not properly
withdrawn the Change of Control Payment for such Notes (or, if all of the Notes are then in global form, make such payment through the facilities of the DTC), 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 $2,000 or an integral multiple of $1,000 in excess
thereof. 

  
 -94-

 If the Change of Control Payment Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest, and Liquidated Damages, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no further interest will be
payable to Holders who tender pursuant to the Change of Control Offer. 
 The Change of Control provisions described above will
apply whether or not any other provisions of this Indenture apply. Except as described above with respect to a Change of Control, this Indenture does not contain provisions that permit the Holders to require that the Issuer repurchase or redeem the
Notes in the event of a takeover, recapitalization or similar transaction. 
 The Issuer will not be required to make a Change
of Control Offer upon a Change of Control if 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 Indenture applicable to a Change of Control Offer made by
the Issuer and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. 
 The Issuer will
comply, to the extent applicable, with the requirements of Rule 14e-1 of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes as a result of a Change of Control. To the extent that the provisions
of any securities laws or regulations conflict with provisions of this Indenture, or compliance with the Change of Control provisions of this Indenture would constitute a violation of any such laws or regulations, the Issuer will comply with the
applicable securities laws and regulations and will not be deemed to have breached its obligations described in this Indenture by virtue of its compliance with such securities laws or regulations. 

SECTION 4.16. Limitation on Sales of Assets and Subsidiary Stock. 

The Issuer will not, and will not permit any of its Restricted Subsidiaries to, make any Asset Disposition unless: 

(1) the Issuer or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset
Disposition at least equal to the fair market value (such fair market value to be determined on the date of contractually agreeing to such Asset Disposition), as determined in good faith by the Board of Directors of the Issuer (including as to the
value of all non-cash consideration), of the shares and assets subject to such Asset Disposition; 
 (2) at least
75% of the consideration received by the Issuer or such Restricted Subsidiary, as the case may be, from such Asset Disposition is in the form of cash or Cash Equivalents or Additional Assets, or any combination thereof; and 

  
 -95-

 (3) except as provided in the next paragraph, an amount equal to 100% of the
Net Available Cash from such Asset Disposition is applied, within one year from the later of the date of such Asset Disposition or the receipt of such Net Available Cash, by the Issuer or such Restricted Subsidiary, as the case may be: 

(a) to the extent the Issuer or any Restricted Subsidiary, as the case may be, elects (or is required by the terms of any
Indebtedness), to prepay, repay, redeem or purchase Indebtedness of the Issuer under the Senior Secured Credit Agreement or any other Indebtedness of the Issuer or a Subsidiary Guarantor (other than Subordinated Obligations, Guarantor Subordinated
Obligations or Indebtedness owed to the Issuer or any of the Issuer’s Affiliates); provided, however, that, in connection with any prepayment, repayment, redemption or purchase of Indebtedness pursuant to this clause (a), the Issuer or
such Restricted Subsidiary will retire such Indebtedness and will cause the related commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid or purchased; or 

(b) to invest in Additional Assets; 
 provided that pending the final application of any such Net Available Cash in accordance with this Section 4.16, the Issuer and its Restricted Subsidiaries may temporarily reduce
Indebtedness or otherwise invest such Net Available Cash in any manner not prohibited by this Indenture. 
 Any Net Available
Cash from Asset Dispositions that is not applied or invested as provided in the preceding paragraph will be deemed to constitute “Excess Proceeds.” Not later than the day following the date that is one year from the later of the
date of such Asset Disposition or the receipt of such Net Available Cash, if the aggregate amount of Excess Proceeds exceeds $10.0 million, the Issuer will be required to make an offer (“Asset Disposition Offer”) to all Holders and
to the extent required by the terms of other Pari Passu Indebtedness, to all holders of such Pari Passu Indebtedness outstanding with similar provisions requiring the Issuer to make an offer to purchase such Pari Passu Indebtedness with the proceeds
from any Asset Disposition (“Pari Passu Notes”), to purchase the maximum principal amount of Notes and any such Pari Passu Notes, as applicable, to which the Asset Disposition Offer applies that may be purchased out of the Excess
Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount (or, in the event such Pari Passu Indebtedness of the Issuer were issued with significant original issue discount, 100% of the accreted value thereof) of the
Notes and Pari Passu Notes, as applicable, plus accrued and unpaid interest and Liquidated Damages, if any (or in respect of such Pari Passu Indebtedness, such lesser price, if any, as may be provided for by the terms of such Indebtedness) to the
date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), in accordance with the procedures set forth in this Indenture

  
 -96-

 
or the agreements governing the Pari Passu Notes, as applicable, in each case in denominations of at least $2,000 or an integral multiple of $1,000 in excess thereof. If the aggregate principal
amount of Notes surrendered by Holders thereof and other Pari Passu Notes, as applicable, surrendered by holders or lenders, collectively, exceeds the amount of Excess Proceeds, the Trustee shall select the Notes to be purchased on a pro rata basis
on the basis of the aggregate principal amount of tendered Notes and Pari Passu Notes, as applicable. To the extent that the aggregate amount of Notes and Pari Passu Notes, as applicable, so validly tendered and not properly withdrawn pursuant to an
Asset Disposition Offer is less than the Excess Proceeds, the Issuer may use any remaining Excess Proceeds for general corporate purposes, subject to the other covenants contained in this Indenture. Upon completion of such Asset Disposition Offer,
the amount of Excess Proceeds shall be reset at zero. 
 The Asset Disposition Offer will remain open for a period of 20
Business Days following its commencement, except to the extent that a longer period is required by applicable law (the “Asset Disposition Offer Period”). No later than five Business Days after the termination of the Asset
Disposition Offer Period (the “Asset Disposition Purchase Date”), the Issuer will purchase the principal amount of Notes and Pari Passu Notes, as applicable, required to be purchased pursuant to this Section 4.16 (the
“Asset Disposition Offer Amount”) or, if less than the Asset Disposition Offer Amount has been so validly tendered, all Notes and Pari Passu Notes, as applicable, validly tendered in response to the Asset Disposition Offer.

 If the Asset Disposition Purchase Date is on or after an interest record date and on or before the related interest payment
date, any accrued and unpaid interest and Liquidated Damages, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no further interest and Liquidated Damages, if any, will be payable
to Holders who tender Notes pursuant to the Asset Disposition Offer. 
 On or before the Asset Disposition Purchase Date, the
Issuer will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Asset Disposition Offer Amount of Notes and Pari Passu Notes or portions of Notes and Pari Passu Notes, as applicable, so validly tendered and
not properly withdrawn pursuant to the Asset Disposition Offer, or if less than the Asset Disposition Offer Amount has been validly tendered and not properly withdrawn, all Notes and Pari Passu Notes, as applicable, so validly tendered and not
properly withdrawn, in each case in denominations of at least $2,000 or an integral multiple of $1,000 in excess thereof. The Issuer will deliver to the Trustee an Officer’s Certificate stating that such Notes or portions thereof were accepted
for payment by the Issuer in accordance with the terms of this Section 4.16 and, in addition, the Issuer will deliver all certificates and notes required, if any, by the agreements governing the Pari Passu Notes. The Issuer or the paying
agent, as the case may be, will promptly (but in any case not later than five Business Days after the termination of the Asset Disposition Offer Period) mail or deliver to each tendering Holder or holder or lender of Pari Passu Notes, as applicable,
an amount equal to the 

  
 -97-

 
purchase price of the Notes or Pari Passu Notes so validly tendered and not properly withdrawn by such holder or lender, as the case may be, and accepted by the Issuer for purchase, and the
Issuer will promptly issue a new Note, and the Trustee, upon delivery of an Officer’s Certificate from the Issuer, will authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the
Note surrendered; provided that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. In addition, the Issuer will take any and all other actions required by the agreements governing
the Pari Passu Notes. Any Note not so accepted will be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer will publicly announce the results of the Asset Disposition Offer on the Asset Disposition Purchase Date. 

The Issuer will comply, to the extent applicable, with the requirements of Rule 14e-1 of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Notes pursuant to this Indenture. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 4.16, the Issuer will comply with the
applicable securities laws and regulations and will not be deemed to have breached its obligations under this Indenture by virtue of its compliance with such securities laws or regulations. 

For the purposes of clause (2) of the first paragraph of this Section 4.16, the following will be deemed to be cash:

 (1) the assumption by the transferee of Indebtedness (other than Subordinated Obligations) of the Issuer or
Indebtedness of a Restricted Subsidiary (other than Guarantor Subordinated Obligations of any Subsidiary Guarantor) and the release of the Issuer or such Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset
Disposition, in which case the Issuer will, without further action, be deemed to have applied such deemed cash to Indebtedness in accordance with clause (3)(a) of the first paragraph of this Section 4.16; and 

(2) securities, notes or other obligations received by the Issuer or any Restricted Subsidiary from the transferee that
are converted by the Issuer or such Restricted Subsidiary into cash within 90 days after receipt thereof. 
 Notwithstanding the
foregoing, the 75% limitation referred to in clause (2) of the first paragraph of this Section 4.16 shall be deemed satisfied with respect to any Asset Disposition in which the cash or Cash Equivalents portion of the consideration
received therefrom, determined in accordance with the foregoing provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Disposition complied with the aforementioned 75% limitation.

 The requirement of clause (3)(b) of the first paragraph of this Section 4.16 above shall be deemed to be
satisfied if an agreement (including a lease, whether a capital 

  
 -98-

 
lease or an operating lease) committing to make the acquisitions or expenditures referred to therein is entered into by the Issuer or its Restricted Subsidiary within the specified time period
and such Net Available Cash is subsequently applied in accordance with such agreement within six months following such agreement. 
 SECTION 4.17. Limitation on Liens. 
 The Issuer will not, and
will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, Incur or suffer to exist any Lien (the “Initial Lien”) other than Permitted Liens upon any of its property or assets (including Capital Stock of
Restricted Subsidiaries), including any income or profits therefrom, whether owned on the date of this Indenture or acquired after that date, which Lien is securing any Indebtedness, unless contemporaneously with the Incurrence of such Liens,
effective provision is made to secure the Indebtedness due under the Notes or, in respect of Liens on any Restricted Subsidiary’s property or assets and any Subsidiary Guarantee of such Restricted Subsidiary, equally and ratably with (or senior
in priority to, in the case of Liens with respect to Subordinated Obligations or Guarantor Subordinated Obligations, as the case may be) the Indebtedness secured by such Lien for so long as such Indebtedness is so secured. 

Any Lien created for the benefit of the Holders of the Notes pursuant to the preceding paragraph shall provide by its terms that such
Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien. 

SECTION 4.18. Limitation on Lines of Business. 

The Issuer will not, and will not permit any Restricted Subsidiary to, engage in any business other than the Oil and Gas Business, except
to the extent as would not be material to the Issuer and its Restricted Subsidiaries taken as a whole. 
 SECTION 4.19.
Additional Subsidiary Guarantees. 
 If the Issuer or any of its Restricted Subsidiaries acquires or
creates another Restricted Subsidiary after the Issue Date, then the Issuer shall cause such Restricted Subsidiary to: 
 (1) execute and deliver to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee pursuant to which such Restricted Subsidiary shall unconditionally Guarantee on a senior
unsecured basis all of the Issuer’s obligations under the Notes and this Indenture on the terms set forth in this Indenture; 
 (2) to the extent that the exchange offer (or filing of a registration statement) pursuant to the Registration Rights Agreement has not been consummated or filed, as applicable, execute and deliver to the
Trustee a joinder, amendment, supplement or 

  
 -99-

 
other instrument pursuant to which such Restricted Subsidiary becomes a party to the Registration Rights Agreement; 

(3) take such further action and execute and deliver such other documents necessary to effectuate the foregoing; and

 (4) deliver to the Trustee an Opinion of Counsel that such supplemental indenture and any other documents
required to be delivered have been duly authorized, executed and delivered by such Restricted Subsidiary and constitute legal, valid, binding and enforceable obligations of such Restricted Subsidiary and such other opinions regarding the perfection
of such Liens in the assets of such Restricted Subsidiary as provided for in this Indenture; 
 provided, however, that
any Restricted Subsidiary that constitutes an Immaterial Subsidiary need not become a Subsidiary Guarantor until such time as it ceases to be an Immaterial Subsidiary. 
 ARTICLE V. 
 SUCCESSOR CORPORATION 

SECTION 5.1. Merger, Consolidation and Sale of Assets. 

The Issuer will not consolidate with or merge with or into or wind up into (whether or not the Issuer is the surviving corporation), or
convey, transfer or lease all or substantially all its assets in one or more related transactions to, any Person, unless: 
 (1) the resulting, surviving or transferee Person (the “Successor Issuer”) will be a corporation, partnership, trust or limited liability company organized and existing under the laws of

substantially all of the properties and assets of one or more Subsidiaries of the Issuer, which properties and assets, if held by the Issuer instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the
Issuer on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Issuer. 
 The Successor Issuer will succeed to, and be substituted for, and may exercise every right and power of, the Issuer under this Indenture, the Notes and the Registration Rights Agreement; and its

 ARTICLE VI. 
 REMEDIES 
 SECTION 6.1. Events of Default. 

An “Event of Default” means any of the following events: 

(1) default in any payment of interest or Liquidated Damages (as required by the Registration Rights Agreement) on any
Note when due, continued for 30 days; 
 (2) default in the payment of principal of or premium, if any, on any
Note when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration of acceleration or otherwise; 
 (3) failure by the Issuer or any Subsidiary Guarantor to comply with its obligations under Section 5.1; 
 (4) failure by the Issuer to comply within 30 days after notice as provided below with any of its obligations under Sections 4.8, 4.10, 4.11, 4.12, 4.13, 4.15,
4.16, 4.17, 4.18 or 4.19 above (in each case, other than a failure to purchase Notes that will constitute an Event of Default under clause (2) above and other than a failure to comply with Section 5.1,
which is covered by clause (3) above); 
 (5) failure by the Issuer to comply within 60 days after notice as
provided below with its other agreements contained in this Indenture; 
 (6) 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 Issuer or any of its Restricted Subsidiaries (or the payment of which is Guaranteed by the Issuer or any
of its Restricted Subsidiaries), other than Indebtedness owed to the Issuer or a Restricted Subsidiary, whether such Indebtedness or Guarantee now exists, or is created after the date of this Indenture, which 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 (and any extensions of any grace period) (“payment default”); or 
 (b) results in the acceleration of such Indebtedness prior to its maturity (the “cross acceleration provision”); 

  
 -103-

 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 $10.0 million or more; 

(7) certain events of bankruptcy, insolvency or reorganization of the Issuer or a Significant Subsidiary or group of
Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Issuer and its Restricted Subsidiaries), would constitute a Significant Subsidiary (the “bankruptcy provisions”);

 (8) failure by the Issuer or any Significant Subsidiary or group of Restricted Subsidiaries that, taken
together (as of the latest audited consolidated financial statements for the Issuer and its Restricted Subsidiaries), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $10.0 million (to the extent not covered
by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid or discharged, and there shall be any period of 60 consecutive days following entry of such final judgment or
decree during which a stay of enforcement of such final judgment or decree, by reason of pending appeal or otherwise, shall not be in effect (the “judgment default provision”); or 

(9) any Subsidiary Guarantee of a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of
the latest audited consolidated financial statements for the Issuer and its Restricted Subsidiaries) would constitute a Significant Subsidiary ceases to be in full force and effect (except as contemplated by the terms of this Indenture) or is
declared null and void in a judicial proceeding or any Subsidiary Guarantor that is a Significant Subsidiary or group of Subsidiary Guarantors that, taken together (as of the latest audited consolidated financial statements of the Issuer and its
Restricted Subsidiaries) would constitute a Significant Subsidiary denies or disaffirms its obligations under this Indenture or its Subsidiary Guarantee. 
 However, a default under clauses (4) and (5) of this paragraph will not constitute an Event of Default until the Trustee or the Holders of 25% in principal amount of the outstanding Notes notify
the Issuer in writing and, in the case of a notice given by the Holders, the Trustee of the default and the Issuer does not cure such default within the time specified in clauses (4) and (5) of this paragraph after receipt of such notice.

 SECTION 6.2. Acceleration. 
 If an Event of Default (other than an Event of Default described in clause (7) above) occurs and is continuing, the Trustee by notice to the Issuer, or the Holders of at least 25% in principal amount
of the outstanding Notes by notice to the Issuer and the Trustee, may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if 

  
 -104-

 
any, accrued and unpaid interest, if any, and Liquidated Damages, if any, on all the Notes to be due and payable. If an Event of Default described in clause (7) above occurs and is
continuing, the principal of, premium, if any, accrued and unpaid interest, if any, and Liquidated Damages, if any, on all the Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or
any Holders. The Holders of a majority in principal amount of the outstanding Notes may waive all past defaults (except with respect to nonpayment of principal, premium, accrued and unpaid interest, if any, or Liquidated Damages, if any) and rescind
any such acceleration with respect to the Notes and its consequences if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of
the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived. 
 SECTION 6.3. Other Remedies. 
 If an Event of Default occurs
and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of the principal of, premium and Liquidated Damages, if any, or interest on the Notes or to enforce the performance of any
provision of the Notes or this Indenture. 
 All rights of action and claims under this Indenture or the Notes may be enforced
by the Trustee 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 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. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law. 

SECTION 6.4. Waiver of Past Defaults. 
 At any time prior to the declaration of acceleration of the Notes, the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may, on
behalf of the Holders of all the Notes, waive any existing Default or Event of Default and its consequences under this Indenture, except a Default or Event of Default specified in Section 6.1(1) or (2) or in respect of any
provision hereof which cannot be modified or amended without the consent of the Holder so affected pursuant to Section 9.2. When a Default or Event of Default is so waived, it shall be deemed cured and shall cease to exist. This
Section 6.4 shall be in lieu of § 316(a)(1)(B) of the TIA and such § 316(a)(1)(B) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by the TIA. 

  
 -105-

 SECTION 6.5. Control by Majority. 

Holders may not enforce this Indenture or the Notes except as provided in this Article VI and under the TIA. The Holders of a majority in
aggregate principal amount of the then outstanding Notes shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee,
provided, however, that the Trustee may refuse to follow any direction (a) that conflicts with any rule of law or this Indenture, (b) that the Trustee reasonably determines may be unduly prejudicial to the rights of any other
Holder, or (c) that may expose the Trustee to personal liability for which reasonable indemnity provided to the Trustee against such liability shall be deemed inadequate by the Trustee; provided, further, however, that the
Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction or this Indenture. This Section 6.5 shall be in lieu of § 316(a)(1)(A) of the TIA, and such § 316(a)(1)(A) of the TIA
is hereby expressly excluded from this Indenture and the Notes, as permitted by the TIA. 
 SECTION 6.6. Limitation on
Suits. 
 Subject to the provisions of this Indenture relating to the duties of the Trustee, if an Event of Default
occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity satisfactory
to it or security against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no Holder may pursue any remedy with respect to this Indenture or the Notes unless:

 (1) such Holder has previously given the Trustee notice that an Event of Default is continuing; 

(2) Holders of at least 25% in principal amount of the outstanding Notes have requested the Trustee to pursue the remedy; 

(3) such Holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense; 

(4) the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of security or
indemnity; and 
 (5) the Holders of a majority in principal amount of the outstanding Notes have not waived such Event of
Default or otherwise given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period. 

  
 -106-

 A Holder may not use this Indenture to prejudice the rights of any other Holders or to
obtain priority or preference over other Holders. 
 SECTION 6.7. Right of Holders To Receive Payment.

 Notwithstanding any other provision in this Indenture, the right of any Holder of a Note to receive payment of the principal
of, premium and Liquidated Damages, if any, and interest on such Note, on or after the respective due dates expressed or provided for in such Note, or to bring suit for the enforcement of any such payment on or after the respective due dates, is
absolute and unconditional and shall not be impaired or affected without the consent of the Holder. 
 SECTION 6.8.
Collection Suit by Trustee. 
 If an Event of Default specified in clause (1) or (2) of
Section 6.1 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer, or any other obligor on the Notes for the whole amount of the principal of, premium, if any,
Liquidated Damages, if any, and accrued interest remaining unpaid, together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate per
annum provided for by the Notes 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 6.9. Trustee May File Proofs of Claim. 

The Trustee may 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, counsel, accountants and experts) and the Holders allowed in any judicial proceedings relative to the Issuer or
Restricted Subsidiaries (or any other obligor upon the Notes), their creditors or their property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the
same, and any Custodian in any such judicial proceedings 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 agent and counsel, and any other amounts due the Trustee under Section 7.7. 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 thereof, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding. 

  
 -107-

 SECTION 6.10. Priorities. 

If the Trustee collects any money pursuant to this Article VI it shall pay out such money in the following order: 

First: to the Trustee for amounts due under Section 7.7; 

Second: to Holders for interest accrued on the Notes, ratably, without preference or priority of any kind, according to
the amounts due and payable on the Notes for interest; 
 Third: to Holders for the principal amounts (including
any premium or Liquidated Damages) owing under the Notes, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for the principal (including any premium or Liquidated Damages); and 

Fourth: the balance, if any, to the Issuer. 
 The Trustee, upon prior written notice to the Issuer, may fix a record date and payment date for any payment to Holders 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 Trustee, a court may in its discretion 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 any suit by the Trustee, any suit by a Holder pursuant to Section 6.7, or a suit by a Holder or
Holders of more than 10% in aggregate principal amount of the outstanding Notes. 
 SECTION 6.12. Restoration of
Rights and Remedies. 
 If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy
under this Indenture or any Note and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case the Issuer, the Trustee and the Holders shall,
subject to any determination in such proceeding, be restored severally and respectively to their former positions under this Indenture, and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding
had been instituted.

 ARTICLE VII. 
 TRUSTEE 
 SECTION 7.1. Duties of Trustee. 

(a) If an Event of Default has occurred, of which the Trustee is deemed to have notice, and is continuing, the Trustee may exercise such
of the rights and powers vested in it by this Indenture and shall use the same degree of care and skill in its exercise thereof as a prudent person would exercise or use in the conduct of his own affairs. 

(b) Except during the continuance of an Event of Default: 

(1) The Trustee need perform only those duties as are specifically set forth in this Indenture and no covenants or
obligations shall be implied in this Indenture that are adverse to the Trustee. The permissive right of the Trustee to do things enumerated in this Indenture shall not be construed as a duty. 

(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, in the case of any such certificates or opinions that by any provision hereof are
specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture. 

(c) Notwithstanding anything to the contrary herein contained, the Trustee may not be relieved from liability 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 7.1. 
 (2) The Trustee shall not be
liable for any error of judgment made in good faith by a Trust Officer, unless it is conclusively determined by a court of competent jurisdiction that the Trustee was negligent in ascertaining the pertinent facts. 

(3) The Trustee shall 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 6.2, 6.4 or 6.5. 

  
 -109-

 (d) No provision of this Indenture shall require the Trustee to expend or risk its own funds
or otherwise incur any financial liability in the performance of any of its duties under this Indenture or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it. 
 (e) Every provision of this Indenture that in any
way relates to the Trustee is subject to paragraphs (a), (b), (c) and (d) of this Section 7.1 and Section 7.2. 
 (f) The Trustee shall not be liable for interest on any money or assets received by it except as the Trustee may agree in writing with the Issuer. Assets held in trust by the Trustee need not be
segregated from other assets except to the extent required by law. 
 SECTION 7.2. Rights of Trustee.

 Subject to Section 7.1: 
 (a) The Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any document believed by it to be genuine and to have been signed or presented by the proper
Person or Persons or to have been prepared and furnished pursuant to any of the provisions of this Indenture; and the Trustee shall be under no duty to make any investigation as to any statement contained in any such instance, but may accept the
same conclusive evidence of the truth and accuracy of such statement or the correctness of such opinions. The Trustee need not investigate any fact or matter stated in the document. 

(b) Before the Trustee acts or refrains from acting, it may consult with counsel of its selection and may require an
Officer’s Certificate or an Opinion of Counsel, which shall conform to Sections 11.4 and 11.5. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such advice or such
Officer’s Certificate or Opinion of Counsel. 
 (c) The Trustee may act through attorneys, agents,
custodians or nominees and shall not be responsible for the misconduct or negligence of any attorney, agent, custodian or nominee appointed with due care. 
 (d) The Trustee shall not be liable for any action that it takes or omits to take in good faith which it reasonably believes to be authorized or within its rights or powers conferred upon it by this
Indenture. 
 (e) The Trustee shall not be bound to make any investigation into the facts or matters stated in
any resolution, certificate, statement, instrument, opinion, notice, request, direction, consent, order, bond, debenture, or other paper or document, but the 

  
 -110-

 
Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled, upon reasonable notice to the Issuer, to examine the books, records, and premises of the Issuer, personally or by agent or attorney and to consult with the officers and representatives of the Issuer, including
the Issuer’s accountants and attorneys. 
 (f) The Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to
the Trustee against the costs, expenses and liabilities which may be incurred by it in compliance with such request, order or direction. 
 (g) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties under this Indenture. 

(h) Delivery of reports, information and documents to the Trustee under Section 4.8 is for informational
purposes only and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its
covenants under this Indenture (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates). 
 (i) Other than a consent revoked in accordance with Section 9.4, any action taken, or omitted to be taken, by the Trustee in good faith pursuant to this Indenture upon the request or authority
or consent of any person who, at the time of making such request or giving such authority or consent, is a Holder shall be conclusive and binding upon every subsequent Holder of a Note or portion of a Note that evidences the same debt as the
requesting or consenting Holder’s Note. 
 SECTION 7.3. 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 Issuer, any
of its respective Subsidiaries, or its respective Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

 SECTION 7.4. Trustee’s Disclaimer. 

The Trustee makes no representation as to the validity or adequacy of this Indenture or the Notes, and it shall not be accountable for
the Issuer’s use of the proceeds from 

  
 -111-

 
the Notes, and it shall not be responsible for any statement of the Issuer in this Indenture or the Notes other than the Trustee’s certificate of authentication. 

Under no circumstances shall the Trustee be liable in its individual capacity for the obligations evidenced by the Notes. In accepting
the trust hereby created, the Trustee acts solely as Trustee for the Holders and not in its individual capacity and all persons, including without limitation the Holders and the Issuer having any claim against the Trustee arising from this Indenture
shall look only to the funds and accounts held by the Trustee hereunder for payment except as otherwise provided herein. 

SECTION 7.5. Notice of Default. 
 If a Default or an Event of Default occurs and is continuing, of which the Trustee is deemed to have notice, the Trustee shall mail to each Holder notice of the uncured Default or Event of Default within
90 days after it occurs and becomes known to the Trustee. Except in the case of a Default or an Event of Default in payment of principal of, or premium, interest or Liquidated Damages, if any, on, any Note, including an accelerated payment, a
Default in payment on the Change of Control Payment Date pursuant to a Change of Control Offer or on the Asset Disposition Purchase Date pursuant to an Asset Disposition Offer and a Default in compliance with Article V hereof, the Trustee may
withhold the notice if and so long as its Board of Directors, the executive committee of its Board of Directors or a committee of its directors and/or Trust Officers in good faith determines that withholding the notice is in the interest of the
Holders. The foregoing sentence of this Section 7.5 shall be in lieu of the proviso to § 315(b) of the TIA and such proviso to § 315(b) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by
the TIA. 
 SECTION 7.6. Reports by Trustee to Holders. 

Within 60 days after May 15 of each year beginning with May 15, 2012 and for so long as Notes remain outstanding, the Trustee
shall, to the extent that any of the events described in TIA § 313(a) occurred within the previous twelve months, but not otherwise, mail to each Holder a brief report dated as of such date that complies with TIA § 313(a). The Trustee also
shall comply with TIA §§ 313(b), (c) and (d). 
 A copy of each report at the time of its mailing to Holders
shall be mailed to the Issuer. 
 The Issuer shall promptly notify the Trustee if the Notes become listed on any stock exchange
and the Trustee shall comply with TIA § 313(d). 

  
 -112-

 SECTION 7.7. Compensation and Indemnity. 

The Issuer shall pay to the Trustee from time to time such compensation for its services as has been agreed to in writing signed by the
Issuer and the Trustee. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made
by it in connection with the performance of its duties under this Indenture. Such expenses shall include the reasonable fees and expenses of the Trustee’s agents, counsel, accountants and experts. 

The Issuer and the Subsidiary Guarantors shall indemnify each of the Trustee (or any predecessor Trustee) and its agents, employees,
shareholders, Affiliates and directors and officers for, and hold them each harmless against, any and all loss, liability, damage, claim or expense (including reasonable fees and expenses of counsel), including taxes (other than taxes based on the
income of the Trustee) incurred by them except for such actions to the extent caused by any negligence, bad faith or willful misconduct on their part, arising out of or in connection with the acceptance or administration of this Indenture including
the reasonable costs and expenses of defending themselves against any claim or liability in connection with the exercise or performance of any of their rights, powers or duties under this Indenture. The Trustee shall notify the Issuer promptly of
any claim asserted against the Trustee for which it may seek indemnity. At the Trustee’s sole discretion, the Issuer or such Subsidiary Guarantor shall defend the claim and the Trustee shall cooperate and may participate in the defense;
provided, however, that any settlement of a claim shall be approved in writing by the Trustee if such settlement would result in an admission of liability by the Trustee or if such settlement would not be accompanied by a full release
of the Trustee for all liability arising out of the events giving rise to such claim. Alternatively, the Trustee may at its option have separate counsel of its own choosing and the Issuer shall pay the reasonable fees and expenses of such counsel.

 To secure the Issuer’s and the Subsidiary Guarantors’ payment obligations in this Section 7.7, the
Trustee shall have a Lien prior to the Notes on all assets or money held or collected by the Trustee, in its capacity as Trustee, except assets or money held in trust to pay principal of or premium, if any, or interest on particular Notes.

 When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(7) or
(8) occurs, such expenses and the compensation for such services are intended to constitute expenses of administration under any Bankruptcy Law. 
 The provisions of this Section 7.7 shall survive the termination of this Indenture or the earlier resignation or removal of the Trustee. 

  
 -113-

 SECTION 7.8. Replacement of Trustee. 

The Trustee may resign at any time by so notifying the Issuer. The Holders of a majority in principal amount of the outstanding Notes may
remove the Trustee and appoint a successor Trustee with the Issuer’s consent, by so notifying the Issuer and the Trustee. The Issuer may remove the Trustee if: 

(1) the Trustee fails to comply with Section 7.10; 

(2) the Trustee is adjudged bankrupt or insolvent; 

(3) a receiver or other public officer takes charge of the Trustee or its property; or 

(4) the Trustee becomes incapable of acting. 
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer shall notify each Holder of such event and shall 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 outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer. 

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Immediately after
that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided in Section 7.7, the resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The Issuer shall mail notice of such successor Trustee’s appointment to each Holder. 

If a successor Trustee does not take office within 45 days after the retiring Trustee resigns or is removed, the retiring Trustee, the
Issuer or the Holders of at least 10% in aggregate principal amount of the outstanding Notes may, at the expense of the Issuer, petition any court of competent jurisdiction for the appointment of a successor Trustee. 

If the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee. 
 Notwithstanding any resignation or replacement of the Trustee
pursuant to this Section 7.8, the Issuer’s obligations under Section 7.7 shall continue for the benefit of the retiring Trustee.

 SECTION 7.9. Successor Trustee by Merger, Etc. 

If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to,
another corporation, the resulting, surviving or transferee corporation without any further act shall, if such resulting, surviving or transferee corporation is otherwise eligible under this Indenture, be the successor Trustee; provided,
however, that such corporation shall be otherwise qualified and eligible under this Article VII. 
 SECTION 7.10.
Eligibility; Disqualification. 
 This Indenture shall always have a Trustee who satisfies the requirement
of TIA §§ 310(a)(1), (2) and (5). The Trustee (or, in the case of a Trustee that is a corporation included in a bank holding company system, the related bank holding company) shall have a combined capital and surplus of at least
$150.0 million as set forth in its most recent published annual report of condition and have a Corporate Trust Office in the City of New York. In addition, if the Trustee is a corporation included in a bank holding company system, the Trustee,
independently of such bank holding company, shall meet the capital requirements of TIA § 310(a)(2). The Trustee shall comply with TIA § 310(b); provided, however, that there shall be excluded from the operation of TIA §
310(b)(1) any indenture or indentures under which other securities, or certificates of interest or participation in other securities, of the Issuer are outstanding, if the requirements for such exclusion set forth in TIA § 310(b)(1) are met.
The provisions of TIA § 310 shall apply to the Issuer, as obligor of the Notes. 
 SECTION 7.11. Preferential
Collection of Claims Against the Issuer. 
 The Trustee shall comply with TIA § 311(a), excluding any creditor
relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. The provisions of TIA § 311 shall apply to the Issuer, as obligor on the Notes.

 SECTION 7.12. Force Majeure. 
 In no event shall the Trustee be liable for any failure or delay in the performance of its obligations under this Indenture because of circumstances beyond the Trustee’s control, including, but not
limited to, acts of God, flood, war (whether declared or undeclared), terrorism, fire, riot, embargo, government action, including any laws, ordinances, regulations, governmental action or the like which delay, restrict or prohibit the providing of
the services contemplated by this Indenture. 

  
 -115-

 SECTION 7.13. Defaults and Events of Default. 

The Trustee shall not be required to take notice or be deemed to have notice of any Default, except failure of the Issuer to cause to be
made any of the payments required to be made to the Trustee, unless the Trustee shall be specifically notified by a writing of such Default by the Issuer or by the Holders of at least 25% in aggregate principal amount of all Notes then outstanding
delivered to the Corporate Trust Office of the Trustee and, in the absence of such notice so delivered, the Trustee may conclusively assume no Default exists. 
 ARTICLE VIII. 
 DISCHARGE OF INDENTURE; DEFEASANCE 

SECTION 8.1. Termination of Issuer’s Obligations. 

This Indenture will be discharged and will cease to be of further effect (except as to surviving rights of registration of transfer or
exchange of the Notes, as expressly provided for in this Indenture) as to all outstanding Notes when (a) either (i) all the Notes, theretofore 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 or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from such trust) have been delivered to the Trustee for cancellation or (ii) all
Notes not theretofore delivered to the Trustee for cancellation have become due and payable or will become due and payable within one year by reason of the giving of a notice of redemption or otherwise and the Issuer or any Subsidiary Guarantor has
irrevocably deposited or caused to be irrevocably deposited with the Trustee as trust funds in trust solely for such purpose, cash in U.S. dollars, U.S. Government Obligations, 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 theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the Notes to the date of maturity
or redemption together with irrevocable instructions from the Issuer directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be; (b) the Issuer has paid all other sums payable under this
Indenture by the Issuer; and (c) the Issuer has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel stating that all conditions precedent under this Indenture relating to the satisfaction and discharge of this
Indenture have been complied with; provided, however, that such counsel may rely, as to matters of fact, on a certificate or certificates of officers of the Issuer. 

The Issuer may, at its option and at any time, elect to have its obligations and the corresponding obligations of the Subsidiary
Guarantors discharged with respect to the outstanding Notes and Subsidiary Guarantees (“Legal Defeasance”). Such Legal Defeasance 

  
 -116-

 
means that the Issuer shall be deemed to have paid and discharged the entire indebtedness represented by the outstanding Notes, and satisfied all of its obligations with respect to the Notes,
except for: (1) the rights of Holders to receive payments in respect of the principal of, premium, if any, and interest on the Notes when such payments are due, (2) the Issuer’s obligations with respect to the Notes concerning issuing
temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payments, (3) the rights, powers, trust, duties and immunities of the Trustee and the Issuer’s obligations in
connection therewith and (4) the Legal Defeasance provisions of this Section 8.1. In addition, the Issuer may, at its option and at any time, elect to terminate its obligations with respect to covenants contained in Sections
4.4, 4.5, 4.8 and 4.10 through 4.19 and Article V and the operation of clauses (6), (7) (with respect to Significant Subsidiaries), (8) and (9) of Section 6.1 and the limitations described
in clause (3) of the first paragraph of Section 5.1 (“Covenant Defeasance”) and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the Notes.
The Issuer may exercise its Legal Defeasance option notwithstanding its prior exercise of its Covenant Defeasance option. In the event of Legal Defeasance, payment of the Notes may not be accelerated because of an Event of Default with respect
thereto. In the event of Covenant Defeasance, payment of the Notes may not be accelerated because of an Event of Default specified in clause (4), (5), (6), (7) (with respect to only to Significant Subsidiaries), (8) or (9) of
Section 6.1 or because of the failure of the Issuer to comply with clause (3) of the first paragraph of Section 5.1. 
 If the Issuer exercises its Legal Defeasance option or its Covenant Defeasance option, each Subsidiary Guarantor will be released from all of its obligations with respect to its Subsidiary Guarantee.

 In order to exercise either Legal Defeasance or Covenant Defeasance: 

(1) the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders cash in United States
dollars, non-callable U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and
interest on the Notes on the stated date for payment thereof or on the applicable Redemption Date, as the case may be; 
 (2) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that (a) the Issuer has
received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon
such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Legal 

  
 -117-

 
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 Covenant Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel
in the United States reasonably acceptable to the Trustee confirming that the Holders 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, of which the Trustee is deemed to have notice, shall have occurred and be continuing on the date of such deposit or insofar as Events of Default under
Section 6.1(7) or (8) from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit; 

(5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default
under this Indenture or any other agreement or instrument to which the Issuer or any of its Restricted Subsidiaries is a party or by which the Issuer or any of its Restricted Subsidiaries is bound; 

(6) the Issuer shall have delivered to the Trustee an Officer’s Certificate stating that the deposit was not made by
the Issuer with the intent of preferring the Holders over any other creditors of the Issuer or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Issuer or any Subsidiary Guarantor or others; 

(7) the Issuer shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating
that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance, as the case may be, have been complied with; provided, however, that such counsel may rely, as to matters of fact, on a
certificate or certificates of officers of the Issuer; and 
 (8) the Issuer shall have delivered to the Trustee an Opinion of
Counsel to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally;
provided, however, that such counsel may rely, as to matters of fact, on a certificate or certificates of officers of the Issuer. 

  
 -118-

 SECTION 8.2. Application of Trust Money. 

The Trustee or Paying Agent shall hold in trust U.S. Legal Tender or U.S. Government Obligations deposited with it pursuant to
Section 8.1, and shall apply the deposited U.S. Legal Tender and the money from U.S. Government Obligations in accordance with this Indenture to the payment of the principal of, premium and Liquidated Damages, if any, and interest on the
Notes. The Trustee shall be under no obligation to invest said U.S. Legal Tender or U.S. Government Obligations except as it may agree in writing with the Issuer. 
 The Issuer and the Subsidiary Guarantors shall pay jointly and severally and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the Legal Tender or U.S. Government
Obligations deposited pursuant to Section 8.1 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of outstanding Notes. 

SECTION 8.3. Repayment to the Issuer. 
 Subject to Section 8.1, the Trustee and the Paying Agent shall promptly pay to the Issuer upon request any excess U.S. Legal Tender or U.S. Government Obligations held by them at any time and
thereupon shall be relieved from all liability with respect to such money. The Trustee and the Paying Agent shall pay to the Issuer upon request any money held by them for the payment of principal, interest or premium or Liquidated Damages, if any,
that remains unclaimed for one year; provided, however, that the Trustee or such Paying Agent, before being required to make any payment, may at the expense of the Issuer cause to be published once in a newspaper of general circulation
in the City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein which shall be at least 30 days from the date of such publication or mailing any unclaimed balance
of such money then remaining will be repaid to the Issuer. After payment to the Issuer, Holders entitled to such money must look to the Issuer for payment as general creditors unless an applicable law designates another Person. 

SECTION 8.4. Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender or U.S. Government Obligations in accordance with Section 8.1 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 Issuer’s and the Subsidiary Guarantors’ obligations under this Indenture and the Notes and the Subsidiary
Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.1 until such time as the Trustee or Paying Agent is permitted to apply all such U.S. Legal Tender or U.S. Government Obligations in
accordance with Section 8.1; provided, however, that if the Issuer has made any payment of interest or premium or Liquidated Damages, if any, on or principal of any Notes because of the reinstatement of its obligations, the
Issuer shall be subrogated to 

  
 -119-

 
the rights of the Holders of such Notes to receive such payment from the U.S. Legal Tender or U.S. Government Obligations held by the Trustee or Paying Agent. 

SECTION 8.5. Acknowledgment of Discharge by Trustee. 

After (i) the conditions of Section 8.1 have been satisfied, (ii) the Issuer has paid or caused to be paid all
other sums payable under this Indenture by the Issuer and (iii) the Issuer has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent referred to in clause (i) of this
Section 8.5 relating to the satisfaction and discharge of this Indenture have been complied with, the Trustee upon request shall acknowledge in writing the discharge of the Issuer’s obligations under this Indenture except for those
surviving obligations specified in Section 8.1, provided the legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or more Officer’s Certificates of the Issuer. 

ARTICLE IX. 

MODIFICATION OF THE INDENTURE 
 SECTION 9.1. Without Consent of Holders. 
 Without the
consent of any Holder, the Issuer, the Subsidiary Guarantors and the Trustee may amend this Indenture and the Notes to: 
 (1) cure any ambiguity, omission, defect, mistake or inconsistency that does not adversely affect the Holders; 
 (2) provide for the assumption by a successor corporation of the obligations of the Issuer or any Subsidiary Guarantor under this Indenture; 

(3) provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the
uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code); 

(4) add Guarantees with respect to the Notes, including Subsidiary Guarantees, or release a Subsidiary Guarantor from its
Subsidiary Guarantee and terminate such Subsidiary Guarantee; provided, however, that the release and termination is in accord with the applicable provisions of this Indenture; 

(5) secure the Notes or Subsidiary Guarantees; 

  
 -120-

 (6) add to the covenants of the Issuer or a Subsidiary Guarantor for the
benefit of the Holders or surrender any right or power conferred upon the Issuer or a Subsidiary Guarantor; 

(7) make any change that does not adversely affect the rights of any Holder; 

(8) comply with any requirement of the SEC in connection with the qualification of this Indenture under the TIA;

 (9) conform the text of this Indenture, the Notes or the Subsidiary Guarantees to any provision of the
“Description of the Notes” under the Offering Circular to the extent that such provision in the “Description of the Notes” under the Offering Circular was intended to be a verbatim recitation of a provision of this Indenture, the
Notes or the Subsidiary Guarantees; 
 (10) if necessary, in connection with any addition or termination or
discharge of any Subsidiary Guarantee, when such termination or discharge is permitted by this Indenture; 
 (11)
provide for the issuance of exchange securities which shall have terms substantially identical in all respects to the Notes (except that the transfer restrictions contained in the Notes shall be modified or eliminated as appropriate) and which shall
be treated, together with any outstanding Notes, as a single class of securities; or 
 (12) provide for the
succession of a successor Trustee under this Indenture. 
 SECTION 9.2. With Consent of Holders.

 All other modifications and amendments of this Indenture and the Notes may be made, subject to certain exceptions, with the
consent of the Holders of a majority in principal amount of the Notes then outstanding (including without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes) and, subject to certain
exceptions, any past default or compliance with any provisions may be waived with the consent of the Holders of a majority in principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a
purchase of, or tender offer or exchange offer for, Notes). However, no amendment may, among other things, without the consent of each Holder of an outstanding Note affected thereby: 

(1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver of any provision
of this Indenture, the Notes or the Subsidiary Guarantees; 

  
 -121-

 (2) reduce the stated rate of or change the stated time for payment of
interest on any Note; 
 (3) reduce the principal of or change the Stated Maturity of any Note; 

(4) reduce the premium payable upon the redemption of any Note pursuant to Section 3.3, or change the time at
which any Note may be redeemed pursuant to Section 3.3, or make any change to the covenants described in Section 4.15 after the occurrence of a Change of Control, or make any change to the provisions relating to an Asset
Disposition Offer that has been made, in each case whether through an amendment or waiver of provisions in the covenants, definitions or otherwise; 
 (5) make any Note payable in money other than that stated in the Note; 
 (6) impair the right of any Holder to receive payment of, premium, if any, principal of and interest on such Holder’s Notes on or after the due dates therefor or to institute suit for the enforcement
of any payment on or with respect to such Holder’s Notes; 
 (7) make any change in the amendment or waiver
provisions which require each Holder’s consent; 
 (8) modify the Subsidiary Guarantees in any manner
adverse to the Holders of the Notes; or 
 (9) make any change to or modify the ranking of the Notes that would
adversely affect the Holders. 
 The consent of the Holders is not necessary under this Indenture to approve the particular form of any proposed
amendment. It is sufficient if such consent approves the substance of the proposed amendment. A consent to any amendment or waiver under this Indenture by any Holder given in connection with a tender of such Holder’s Notes will not be rendered
invalid by such tender. After an amendment under this Indenture becomes effective, the Issuer is required to mail to the Holders a notice briefly describing such amendment. However, failure to give such notice to all the Holders, or any defect in
the notice will not impair or affect the validity of the amendment. 
 SECTION 9.3. Compliance with Trust Indenture
Act. 
 Every amendment, waiver or supplement of this Indenture or the Notes shall comply with the TIA as then in
effect; provided, however, that this Section 9.3 shall not of itself require that this Indenture or the Trustee be qualified under the TIA or constitute any 

  
 -122-

 
admission or acknowledgment by any party hereto that any such qualification is required prior to the time this Indenture and the Trustee are required by the TIA to be so qualified. 

SECTION 9.4. Revocation and Effect of Consents. 

Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder 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. Subject to the following paragraph, any such Holder or subsequent Holder may
revoke the consent as to such Holder’s Note or portion of such Note by notice to the Trustee or the Issuer received before the date on which the Trustee receives an Officer’s Certificate certifying that the Holders of the requisite
principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. An amendment, supplement or waiver becomes effective upon receipt by the Trustee of such Officer’s Certificate and
evidence of consent by the Holders of the requisite percentage in principal amount of outstanding Notes. 
 The Issuer may, but
shall not be obligated to, fix a Record Date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver, which Record Date shall be at least 30 days prior to the first solicitation of such consent. If a
Record Date is fixed, then notwithstanding the second sentence of the immediately preceding paragraph, those Persons who were Holders at such Record Date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any
consent previously given, whether or not such Persons continue to be Holders after such Record Date. No such consent shall be valid or effective for more than 90 days after such Record Date unless consents from Holders of the requisite percentage in
principal amount of outstanding Notes required under this Indenture for the effectiveness of such consents shall have also been given and not revoked within such 90 day period. 

SECTION 9.5. Notation on or Exchange of Notes. 

If an amendment, supplement or waiver changes the terms of a Note, the Trustee may require the Holder of such Note to deliver it to the
Trustee. The Trustee may place an appropriate notation on the Note about the changed terms and return it to the Holder. Alternatively, if the Issuer or the Trustee so determines, the Issuer in exchange for the Note shall issue and the Trustee shall
authenticate a new Note that reflects the changed terms. 
 SECTION 9.6. Trustee To Sign Amendments, Etc.

 The Trustee shall execute any amendment, supplement or waiver authorized pursuant to this Article IX; provided,
however, that the Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee’s own rights, duties or immunities under this Indenture. In executing such supplement or waiver the

  
 -123-

 
Trustee shall be entitled to receive indemnity reasonably satisfactory to it, and shall be fully protected in relying upon an Opinion of Counsel and an Officer’s Certificate of the Issuer,
stating that no event of default shall occur as a result of such amendment, supplement or waiver and that the execution of any amendment, supplement or waiver authorized pursuant to this Article IX is authorized or permitted by this Indenture,
provided the legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or more Officer’s Certificates of the Issuer. Such Opinion of Counsel shall not be an expense of the Trustee.

Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture, other than the
Officer’s Certificate required by Section 4.6, shall comply with TIA § 314(e) and include:

or required by law to close. If a payment date is a Legal Holiday at such place, payment may be made at such place on the next succeeding day that is not a Legal Holiday, and no interest shall
accrue for the intervening period. 
 SECTION 11.8. Governing Law. 

THIS INDENTURE , THE NOTES AND THE SUBSIDIARY GUARANTEES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NEW YORK. Each of the parties hereto agrees to submit to the jurisdiction of the courts of the State of New York in any action or proceeding arising out of or relating to this Indenture. 

SECTION 11.9. No Adverse Interpretation of Other Agreements. 

This Indenture may not be used to interpret another indenture, loan or debt agreement of the Issuer or any of its respective
Subsidiaries. Any such indenture, loan or debt agreement may not be used to interpret this Indenture. 
 SECTION 11.10.
No Personal Liability. 
 No director, officer, employee, incorporator or shareholder of the Issuer or any

shall not in any way be affected or impaired thereby, it being intended that all of the provisions hereof shall be enforceable to the full extent permitted by law. 

SECTION 11.14. Independence of Covenants. 
 All covenants and agreements in this Indenture and the Notes shall be given independent effect so that if any particular action or condition is not permitted by any of such covenants, the fact that it

 SECTION 12.1. Unconditional Subsidiary Guarantee. 
 Subject
to the provisions of this Article XII, each Subsidiary Guarantor, if any, hereby, jointly and severally, unconditionally and irrevocably Guarantees, on an unsecured senior basis 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 Issuer or any other Subsidiary Guarantors to the Holders or the Trustee under this Indenture or
thereunder, that: (a) the principal of, premium and Liquidated Damages, if any, and interest on the Notes shall be duly and punctually paid in full when due, whether at maturity, upon redemption at the option of Holders pursuant to the
provisions of the Notes relating thereto, by acceleration or otherwise, and interest on the overdue principal and (to the extent permitted by law) interest, if any, on the Notes and all other obligations of the Issuer or the Subsidiary Guarantors to
the Holders or the Trustee under this Indenture or thereunder (including amounts due the Trustee under Section 7.7 hereof) and all other obligations shall be promptly paid in full or performed, all in accordance with the terms hereof and
thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal,
whether at maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed, or failing performance of any other obligation of the Issuer to the Holders under this Indenture or under the Notes, for whatever reason, each
Subsidiary Guarantor shall be obligated to pay, or to perform or cause the performance of, the same immediately. An Event of Default under this Indenture or the Notes shall constitute an event of default under the Subsidiary Guarantees, and shall
entitle the Holders of Notes to accelerate the obligations of the Subsidiary Guarantors under this Indenture in the same manner and to the same extent as the obligations of the Issuer. 

  
 -128-

 Each of the Subsidiary Guarantors hereby agrees that its obligations under this Indenture
shall be 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, any release of any other Subsidiary Guarantor, the recovery of any judgment against the Issuer, any action to enforce the same, whether or not a Subsidiary Guarantee is affixed to any particular Note, or any other circumstance which
might otherwise constitute a legal or equitable discharge or defense of a Subsidiary Guarantor. Each of the Subsidiary Guarantors hereby waives the benefit of diligence, presentment, demand of payment, filing of claims with a court in the event of
insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and covenants that its Subsidiary Guarantee shall not be discharged except by complete performance of the
obligations contained in the Notes, this Indenture and this Subsidiary Guarantee. Each Subsidiary Guarantee is a guarantee of payment and not of collection. If any Holder or the Trustee is required by any court or otherwise to return to the Issuer
or to any Subsidiary Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuer or such Subsidiary Guarantor, any amount paid by the Issuer or such Subsidiary Guarantor to the Trustee or such Holder,
this Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Subsidiary Guarantor further agrees that, as between it, on the one hand, and the Holders of Notes and the Trustee, on the other
hand, (a) subject to this Article XII, the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI hereof for the purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby, and (b) in the event of any acceleration of such obligations as provided in Article VI hereof, such obligations (whether or not due and payable) shall forthwith
become due and payable by the Subsidiary Guarantors for the purpose of its Subsidiary Guarantee. 
 No shareholder, officer,
director, employee, partner or incorporator, past, present or future, or any Subsidiary Guarantor, as such, shall have any personal liability under the Subsidiary Guarantees by reason of his, her or its status as such shareholder, officer, director,
employee, partner or incorporator. 
 SECTION 12.2. Limitations on Subsidiary Guarantees. 

The obligations of each Subsidiary Guarantor under its Subsidiary Guarantee will be limited to the maximum amount which, after giving
effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other
Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to its contribution obligations under this Indenture, will result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance
or fraudulent transfer under federal or state law. 

  
 -129-

 SECTION 12.3. Execution and Delivery of Subsidiary Guarantee Notation.

 To further evidence its Subsidiary Guarantee set forth in Section 12.1, each Subsidiary Guarantor hereby agrees
that a notation of such Subsidiary Guarantee, substantially in the form of Exhibit E herein, shall be endorsed on each Note authenticated and delivered by the Trustee. Such notation shall be executed on behalf of each Subsidiary Guarantor by
either manual or facsimile signature of one Officer of each Subsidiary Guarantor, who, in each case, shall have been duly authorized to so execute by all requisite corporate action. The validity and enforceability of any Subsidiary Guarantee shall
not be affected by the fact that such notation is not affixed to any particular Note. 
 Each of the Subsidiary Guarantors
hereby agrees that its Subsidiary Guarantee set forth in Section 12.1 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Subsidiary Guarantee. 

If an Officer of a Subsidiary Guarantor whose signature is on this Indenture or on a notation of a Subsidiary Guarantee no longer holds
that office at the time the Trustee authenticates the Note on which such notation is endorsed or at any time thereafter, such Subsidiary Guarantor’s Subsidiary Guarantee of such Note shall be valid nevertheless. 

The delivery of any Note by the Trustee, after the authentication thereof under this Indenture, shall constitute due delivery of any
Subsidiary Guarantee set forth in this Indenture on behalf of each Subsidiary Guarantor. 
 SECTION 12.4. Release of a
Subsidiary Guarantor. 
 (a) If no Default exists or would exist under this Indenture, (i) upon the sale or
disposition of all of the Capital Stock of a Subsidiary Guarantor by either Issuer or a Restricted Subsidiary of such Issuer in a transaction constituting an Asset Disposition in accordance with Section 4.16, or upon the consolidation or
merger of a Subsidiary Guarantor with or into any Person in compliance with Article V (in each case, other than to either Issuer or an Affiliate of either Issuer or a Restricted Subsidiary), or (ii) upon the designation of a Subsidiary
Guarantor as an Unrestricted Subsidiary in accordance with Section 4.14 or in connection with any Legal Defeasance or satisfaction and discharge of the Notes as provided in Section 8.1, such Subsidiary Guarantor and each
Subsidiary of such Subsidiary Guarantor that is also a Subsidiary Guarantor shall be deemed released from all obligations under this Article XII without any further action required on the part of the Trustee or any Holder; provided,
however, that each such Subsidiary Guarantor is sold or disposed of or designated in accordance with this Indenture. Any Subsidiary Guarantor not so released or the entity surviving such Subsidiary Guarantor, as applicable, shall remain or be
liable under its Subsidiary Guarantee as provided in this Article XII. 

  
 -130-

 (b) The Trustee shall deliver an appropriate instrument evidencing the release of a
Subsidiary Guarantor upon receipt of a request by the Issuer or such Subsidiary Guarantor accompanied by an Officer’s Certificate and an Opinion of Counsel certifying as to the compliance with this Section 12.4, provided the
legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or more Officers Certificates of the Issuer. 
 The Trustee shall execute any documents reasonably requested by the Issuer or a Subsidiary Guarantor in order to evidence the release of such Subsidiary Guarantor from its obligations under its Subsidiary
Guarantee endorsed on the Notes and under this Article XII. 
 Except as set forth in Articles Four and Five and this
Section 12.4, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Subsidiary Guarantor with or into the Issuer or another Subsidiary Guarantor or shall prevent any sale or conveyance
of the property of a Subsidiary Guarantor as an entirety or substantially as an entirety to the Issuer or another Subsidiary Guarantor. 
 SECTION 12.5. Waiver of Subrogation. 
 Until this Indenture
is discharged and all of the Notes are discharged and paid in full, each Subsidiary Guarantor hereby irrevocably waives and agrees not to exercise any claim or other rights which it may now or hereafter acquire against the Issuer that arise from the
existence, payment, performance or enforcement of the Issuer’s obligations under the Notes or this Indenture and such Subsidiary Guarantor’s obligations under its Subsidiary Guarantee and this Indenture, in any such instance including,
without limitation, any right of subrogation, reimbursement, exoneration, contribution, indemnification, and any right to participate in any claim or remedy of the Holders against the Issuer, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Issuer, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of
such claim or other rights. If any amount shall be paid to any Subsidiary Guarantor in violation of the preceding sentence and any amounts owing to the Trustee or the Holders of Notes under the Notes, this Indenture, or any other document or
instrument delivered under or in connection with such agreements or instruments, shall not have been paid in full, such amount shall have been deemed to have been paid to such Subsidiary Guarantor for the benefit of, and held in trust for the
benefit of, the Trustee or the Holders and shall forthwith be paid to the Trustee for the benefit of itself or such Holders to be credited and applied to the obligations in favor of the Trustee or the Holders, as the case may be, whether matured or
unmatured, in accordance with the terms of this Indenture. Each Subsidiary Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the waiver set forth in this
Section 12.5 is knowingly made in contemplation of such benefits. 

  
 -131-

 SECTION 12.6. Immediate Payment. 

Each Subsidiary Guarantor agrees to make immediate payment to the Trustee on behalf of the Holders of all obligations under the Notes and
this Indenture owing or payable to the respective Holders upon receipt of a demand for payment therefor by the Trustee to such Subsidiary Guarantor in writing. 
 SECTION 12.7. No Set-Off. 
 Each payment to be made by a
Subsidiary Guarantor under this Indenture in respect of the obligations under the Notes and this Indenture shall be payable in the currency or currencies in which such obligations are denominated, and shall be made without set-off, counterclaim,
reduction or diminution of any kind or nature. 
 SECTION 12.8. Obligations Absolute. 

The obligations of each Subsidiary Guarantor under this Indenture are and shall be absolute and unconditional and any monies or amounts
expressed to be owing or payable by each Subsidiary Guarantor under this Indenture which may not be recoverable from such Subsidiary Guarantor on the basis of a Subsidiary Guarantee shall be recoverable from such Subsidiary Guarantor as a primary
obligor and principal debtor in respect thereof. 
 SECTION 12.9. Obligations Continuing. 

The obligations of each Subsidiary Guarantor under this Indenture shall be continuing and shall remain in full force and effect until all
the obligations have been paid and satisfied in full. Each Subsidiary Guarantor agrees with the Trustee that it will from time to time deliver to the Trustee suitable acknowledgments of this continued liability under this Indenture and under any
other instrument or instruments in such form as counsel to the Trustee may advise and as will prevent any action brought against it in respect of any default under this Indenture being barred by any statute of limitations now or hereafter in force
and, in the event of the failure of a Subsidiary Guarantor so to do, it hereby irrevocably appoints the Trustee the attorney and agent of such Subsidiary Guarantor to make, execute and deliver such written acknowledgment or acknowledgments or other
instruments as may from time to time become necessary or advisable, in the judgment of the Trustee on the advice of counsel, to fully maintain and keep in force the liability of such Subsidiary Guarantor under this Indenture. 

SECTION 12.10. Obligations Not Reduced. 
 The obligations of each Subsidiary Guarantor under this Indenture shall not be satisfied, reduced or discharged solely by the payment of such principal, premium, if any, interest, fees and other monies or
amounts as may at any time prior to discharge of this Indenture 

  
 -132-

 
pursuant to Article VIII be or become owing or payable under or by virtue of or otherwise in connection with the Notes or this Indenture. 

SECTION 12.11. Obligations Reinstated. 
 The obligations of each Subsidiary Guarantor under this Indenture shall continue to be effective or shall be reinstated, as the case may be, if at any time any payment which would otherwise have reduced
the obligations of any Subsidiary Guarantor under this Indenture (whether such payment shall have been made by or on behalf of the Issuer or by or on behalf of a Subsidiary Guarantor) is rescinded or reclaimed from any of the Holders upon the
insolvency, bankruptcy, liquidation or reorganization of the Issuer or any Subsidiary Guarantor or otherwise, all as though such payment had not been made. If demand for, or acceleration of the time for, payment by the Issuer is stayed upon the
insolvency, bankruptcy, liquidation or reorganization of the Issuer, all such Indebtedness otherwise subject to demand for payment or acceleration shall nonetheless be payable by each Subsidiary Guarantor as provided herein. 

SECTION 12.12. Obligations Not Affected. 
 The obligations of each Subsidiary Guarantor under this Indenture shall not be affected, impaired or diminished in any way by any act, omission, matter or thing whatsoever, occurring before, upon or after
any demand for payment under this Indenture (and whether or not known or consented to by any Subsidiary Guarantor or any of the Holders) which, but for this provision, might constitute a whole or partial defense to a claim against any Subsidiary
Guarantor under this Indenture or might operate to release or otherwise exonerate any Subsidiary Guarantor from any of its obligations under this Indenture or otherwise affect such obligations, whether occasioned by default of any of the Holders or
otherwise, including, without limitation: 
 (a) any limitation of status or power, disability, incapacity or
other circumstance relating to the Issuer or any other person, including any insolvency, bankruptcy, liquidation, reorganization, readjustment, composition, dissolution, winding up or other proceeding involving or affecting the Issuer or any other
person; 
 (b) any irregularity, defect, unenforceability or invalidity in respect of any Indebtedness or other
obligation of the Issuer or any other person under this Indenture, the Notes or any other document or instrument; 
 (c) any failure of the Issuer, whether or not without fault on its part, to perform or comply with any of the provisions of this Indenture or the Notes, or to give notice thereof to a Subsidiary
Guarantor; 

  
 -133-

 (d) the taking or enforcing or exercising or the refusal or neglect to take
or enforce or exercise any right or remedy from or against the Issuer or any other person or their respective assets or the release or discharge of any such right or remedy; 

(e) the granting of time, renewals, extensions, compromises, concessions, waivers, releases, discharges and other
indulgences to the Issuer or any other Person; 
 (f) any change in the time, manner or place of payment of, or
in any other term of, any of the Notes, or any other amendment, variation, supplement, replacement or waiver of, or any consent to departure from, any of the Notes or this Indenture, including, without limitation, any increase or decrease in the
principal amount of or premium, if any, or interest on any of the Notes; 
 (g) any change in the ownership,
control, name, objects, businesses, assets, capital structure or constitution of the Issuer or a Subsidiary Guarantor; 
 (h) any merger or amalgamation of the Issuer or a Subsidiary Guarantor with any Person or Persons; 
 (i) the occurrence of any change in the laws, rules, regulations or ordinances of any jurisdiction by any present or future action of any governmental authority or court amending, varying, reducing or
otherwise affecting, or purporting to amend, vary, reduce or otherwise affect, any of the Issuer’s obligations under the Notes or this Indenture or the obligations of a Subsidiary Guarantor under its Subsidiary Guarantee; and 

(j) any other circumstance (other than by complete, irrevocable payment), including release of any other Subsidiary
Guarantor pursuant to Section 12.4, that might otherwise constitute a legal or equitable discharge or defense of the Issuer under this Indenture or the Notes or of a Subsidiary Guarantor in respect of its Subsidiary Guarantee under this
Indenture. 
 SECTION 12.13. Waiver. 

Without in any way limiting the provisions of Section 12.1 hereof, each Subsidiary Guarantor hereby waives notice of
acceptance hereof, notice of any liability of any Subsidiary Guarantor under this Indenture, notice or proof of reliance by the Holders upon the obligations of any Subsidiary Guarantor under this Indenture, and diligence, presentment, demand for
payment on the Issuer, protest, notice of dishonor or non-payment of any of the Issuer’s obligations, under the notes or this Indenture, or other notice or formalities to the Issuer or any Subsidiary Guarantor of any kind whatsoever.

  
 -134-

 SECTION 12.14. No Obligation To Take Action Against the
Issuer. 
 Neither the Trustee nor any other Person shall have any obligation to enforce or exhaust
any rights or remedies or to take any other steps under any security for the Issuer’s obligations under the notes or this Indenture, or against the Issuer or any other Person or any Property of the Issuer or any other Person before the Trustee
is entitled to demand payment and performance by any or all Subsidiary Guarantors of their liabilities and obligations under their Subsidiary Guarantees or under this Indenture. 

SECTION 12.15. Dealing with the Issuer and Others. 

The Holders, without releasing, discharging, limiting or otherwise affecting in whole or in part the obligations and liabilities of any
Subsidiary Guarantor under this Indenture and without the consent of or notice to any Subsidiary Guarantor, may 

(a) grant time, renewals, extensions, compromises, concessions, waivers, releases, discharges and other indulgences to the
Issuer or any other Person; 
 (b) take or abstain from taking security or collateral from the Issuer or from
perfecting security or collateral of the Issuer; 
 (c) release, discharge, compromise, realize, enforce or
otherwise deal with or do any act or thing in respect of (with or without consideration) any and all collateral, mortgages or other security given by the Issuer or any third party with respect to the obligations or matters contemplated by this
Indenture or the Notes; 
 (d) accept compromises or arrangements from the Issuer; 

(e) apply all monies at any time received from the Issuer or from any security upon such part of the Issuer’s
obligations under the Notes and this Indenture as the Holders may see fit or change any such application in whole or in part from time to time as the Holders may see fit; and 

(f) otherwise deal with, or waive or modify their right to deal with, the Issuer and all other Persons and any security as
the Holders or the Trustee may see fit. 
 SECTION 12.16. Default and Enforcement. 

If any Subsidiary Guarantor fails to pay in accordance with Section 12.6 hereof, the Trustee may proceed in its name as
trustee under this Indenture in the enforcement of the Subsidiary Guarantee of any such Subsidiary Guarantor and such Subsidiary Guarantor’s obligations thereunder and under this Indenture by any remedy provided by law, whether

  
 -135-

 
by legal proceedings or otherwise, and to recover from such Subsidiary Guarantor its obligations thereunder and under this Indenture. 

SECTION 12.17. Amendment, Etc. 
 No amendment, modification or waiver of any provision of this Indenture relating to any Subsidiary Guarantor or consent to any departure by any Subsidiary Guarantor or any other Person from any such
provision will in any event be effective unless it is signed by such Subsidiary Guarantor and the Trustee. 
 SECTION 12.18.
Acknowledgment. 
 Each Subsidiary Guarantor hereby acknowledges communication of the terms of this
Indenture and the Notes and consents to and approves of the same.

without limitation, legal fees on a solicitor and client basis) incurred by the Trustee, its agents, advisors and counsel or any of the Holders in enforcing any of their rights under any Subsidiary Guarantee. 

SECTION 12.20. No Merger or Waiver; Cumulative Remedies. 

No Subsidiary Guarantee shall operate by way of merger of any of the obligations of a Subsidiary Guarantor under any other agreement,
including, without limitation, this Indenture. No failure to exercise and no delay in exercising, on the part of the Trustee or the Holders, any right, remedy, power or privilege under this Indenture or under this Indenture or the Notes, shall
operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege under this Indenture or under this Indenture or the Notes preclude any other or further exercise thereof or the exercise of any other
right, remedy, power or privilege. The rights, remedies, powers and privileges in the Subsidiary Guarantee and under this Indenture, the Notes and any other document or instrument between a Subsidiary Guarantor and/or the Issuer and the Trustee are
cumulative and not exclusive of any rights, remedies, powers and privilege provided by law. 
 SECTION 12.21. Survival
of Obligations. 
 Without prejudice to the survival of any of the other obligations of each Subsidiary Guarantor
under this Indenture, the obligations of each Subsidiary Guarantor under Section 12.1 shall survive the payment in full of the Issuer’s obligations under the Notes and this Indenture and shall be enforceable against such Subsidiary
Guarantor without regard to 

  
 -136-

 
and without giving effect to any defense, right of offset or counterclaim available to or which may be asserted by the Issuer or any Subsidiary Guarantor. 

SECTION 12.22. Subsidiary Guarantee in Addition to Other Obligations. 

The obligations of each Subsidiary Guarantor under its Subsidiary Guarantee and this Indenture are in addition to and not in substitution
for any other obligations to the Trustee or to any of the Holders in relation to this Indenture or the Notes and any guarantees or security at any time held by or for the benefit of any of them. 

SECTION 12.23. Severability. 
 Any provision of this Article XII which is prohibited or unenforceable in any jurisdiction shall not invalidate the remaining provisions and any such prohibition or unenforceability in any jurisdiction
shall not invalidate or render unenforceable such provision in any other jurisdiction unless its removal would substantially defeat the basic intent, spirit and purpose of this Indenture and this Article XII. 

SECTION 12.24. Successors and Assigns. 
 Each Subsidiary Guarantee shall be binding upon and inure to the benefit of each Subsidiary Guarantor and the Trustee and the other Holders and their respective successors and permitted assigns, except
that no Subsidiary Guarantor may assign any of its obligations under this Indenture or thereunder.

 (REVERSE OF SECURITY) 

11.375% Senior Note due 2019 
 (1) Interest. GMX RESOURCES INC. (the “Issuer”) promises to pay interest on the principal amount of this Note at the rate per annum shown above and Liquidated Damages, if any,
payable pursuant to Section 6 of the Registration Rights Agreement referred to below. Interest on the Notes will accrue from the most recent date on which interest has been paid or, if no interest has been paid, from February 9, 2011. The
Issuer will pay interest and Liquidated Damages, if any, semi-annually in arrears on each Interest Payment Date, commencing August 15, 2011. Interest will be computed on the basis of a 360-day year of twelve 30-day months and, in the case of a
partial month, the actual number of days elapsed. 
 The Issuer shall pay interest on overdue principal and on overdue
installments of interest and Liquidated Damages, if any, from time to time on demand at a rate of two percentage points per annum in excess of the rate borne by the Notes and on overdue installments of interest (without regard to any applicable
grace periods) to the extent lawful. 
 (2) Method of Payment. The Issuer shall pay interest and Liquidated Damages, if
any, on the Notes (except defaulted interest) to the Persons who are the registered Holders at the close of business on the Record Date immediately preceding the Interest Payment Date even if the Notes are canceled on registration of transfer or
registration of exchange after such Record Date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Issuer shall pay principal, premium and Liquidated Damages, if any, and interest in money of the United States that at
the time of payment is legal tender for payment of public and private debts (“U.S. Legal Tender”). The Issuer may deliver any such interest payment to the Paying Agent or to a Holder at the Holder’s registered address.

 (3) Paying Agent and Registrar. Initially, The Bank of New York Mellon Trust Company, N.A., (the
“Trustee”) will act as Paying Agent and Registrar. The Issuer may change any Paying Agent, Registrar or co-Registrar without notice to the Holders. 
 (4) Indenture. The Issuer issued the Notes under an Indenture, dated as of February 9, 2011 (the “Indenture”), among the Issuer, the Subsidiary Guarantors and the Trustee.
This Note is one of a duly authorized issue of Notes of the Issuer designated as its 11.375% Senior Notes due 2019 (the “Notes”). The Notes include any Additional Notes. The Notes and any Additional Notes are treated as a single
class of securities under the Indenture. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to
the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”), as in effect on the date of the Indenture. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders
of Notes are referred to the Indenture and said Act for a statement of them. The Notes are general unsecured obligations of the 

  
 A-3

 
Issuer. Payment on each Note is guaranteed on a senior basis by the Subsidiary Guarantors pursuant to Article XII of the Indenture. Each Holder, by accepting a Note, agrees to be bound by all of
the terms and provisions of the Indenture, as the same may be amended from time to time in accordance with its terms. 
 (a) (5)
Redemption. (a) Except as described in subparagraphs (b) and (c) below, the Issuer will not be entitled to redeem the Notes at its option prior to February 15, 2015. The Notes will be redeemable, at the Issuer’s
option, in whole at any time or in part from time to time, on and after February 15, 2015, upon not less than 30 nor more than 60 prior days’ notice, at the following Redemption Prices (expressed as a percentages of the principal amount of
the Notes) plus accrued and unpaid interest on the Notes, if any, to the applicable Redemption Date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date), if redeemed
during the twelve-month period beginning on February 15 of the years set forth below:

 (b) At any time on or
prior to February 15, 2014, the Issuer may, at its option, on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes (including Additional Notes) issued under this Indenture with the Net Cash Proceeds of one

11.375% Senior Notes due 2019 
 REGISTRATION RIGHTS AGREEMENT 
 February 9, 2011 

CREDIT SUISSE SECURITIES (USA) LLC 
 MORGAN STANLEY & CO. INCORPORATED, 
 As Representatives of the several Initial Purchasers, 
 c/o Credit Suisse Securities (USA) LLC

       Eleven Madison Avenue 
       New York, New York 10010-3629 
 c/o Morgan Stanley &
Co. Incorporated 
 1585 Broadway 
 New
York, New York 10036 
 Dear Sirs: 
 GMX Resources Inc., an Oklahoma corporation (the “Issuer”), proposes to issue and sell to Credit Suisse Securities (USA) LLC and Morgan Stanley & Co. Incorporated, the representatives
(the “Representatives”) of the several initial purchasers named in Schedule A to the Purchase Agreement (collectively, the “Initial Purchasers”), upon the terms set forth in a purchase agreement of even date herewith (the
“Purchase Agreement”), $200,000,000 aggregate principal amount of its 11.375% Senior Notes due 2019 (the “Initial Securities”) to be unconditionally guaranteed (the “Guaranties”) by Diamond Blue Drilling Co. and
Endeavor Pipeline Inc. (the “Guarantors” and together with the Issuer, the “Company”). The Initial Securities will be issued pursuant to an Indenture, dated as of February 9, 2011 (the “Indenture”) among the
Issuer, the Guarantors named therein and The Bank of New York Mellon Trust Company, N.A. (the “Trustee”). As an inducement to the Initial Purchasers, the Company agrees with the Initial Purchasers, for the benefit of the holders of the
Initial Securities (including, without limitation, the Initial Purchasers), the Exchange Securities (as defined below) and the Private Exchange Securities (as defined below) (collectively the “Holders”), as follows: 

1. Registered Exchange Offer. Unless the Registered Exchange Offer (as defined below) would violate applicable law or
interpretation of the staff of the Securities and Exchange Commission (the “Commission”) the Company shall, at its own cost, use its best efforts to prepare, not later than 180 days after (or if the 180th day is not a business day, the
first business day thereafter) the date of original issue of the Initial Securities (the “Issue Date”), file with the Commission a registration statement (the “Exchange Offer Registration Statement”) on an appropriate form under
the Securities Act of 1933, as amended (the “Securities Act”), with respect to a proposed offer (the “Registered Exchange Offer”) to the Holders of 

  
 1 

 
Transfer Restricted Securities (as defined in Section 6 hereof), who are not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer, to issue
and deliver to such Holders, in exchange for the Initial Securities, a like aggregate principal amount of debt securities (the “Exchange Securities”) of the Company issued under the Indenture and identical in all material respects to the
Initial Securities (except for the transfer restrictions relating to the Initial Securities and the provisions relating to the matters described in Section 6 hereof) that would be registered under the Securities Act. The Company shall use its
reasonable best efforts to cause such Exchange Offer Registration Statement to become effective under the Securities Act within 360 days (or if the 360th day is not a business day, the first business day thereafter) after the Issue Date of the
Initial Securities and shall keep the Exchange Offer Registration Statement effective for not less than 30 days (or longer, if required by applicable law) after the date notice of the Registered Exchange Offer is mailed to the Holders (such
period being called the “Exchange Offer Registration Period”). 
 If the Company effects the Registered Exchange
Offer, the Company will be entitled to close the Registered Exchange Offer 30 days after the commencement thereof (or longer, if required by applicable law) provided that the Company has accepted all the Initial Securities theretofore validly
tendered in accordance with the terms of the Registered Exchange Offer. 
 Promptly following the declaration of the
effectiveness of the Exchange Offer Registration Statement, the Company shall commence the Registered Exchange Offer, it being the objective of such Registered Exchange Offer to enable each Holder of Transfer Restricted Securities (as defined in
Section 6 hereof) electing to exchange the Initial Securities for Exchange Securities (assuming that such Holder is not an affiliate of the Company within the meaning of the Securities Act, acquires the Exchange Securities in the ordinary
course of such Holder’s business and has no arrangements with any person to participate in the distribution of the Exchange Securities and is not prohibited by any law or policy of the Commission from participating in the Registered Exchange
Offer) to trade such Exchange Securities from and after their receipt without any limitations or restrictions under the Securities Act and without material restrictions under the securities laws of the several states of the United States; provided,
however, that Participating Broker-Dealers (as defined below) receiving Exchange Notes in the Registered Exchange Offer will have a prospectus delivery requirement with respect to the resale of such Exchange Notes. 

The Company acknowledges that, pursuant to current interpretations by the Commission’s staff of Section 5 of the Securities
Act, in the absence of an applicable exemption therefrom, (i) each Holder which is a broker-dealer electing to exchange Securities, acquired for its own account as a result of market making activities or other trading activities, for Exchange
Securities (an “Exchanging Dealer”), is required to deliver a prospectus containing the information set forth in (a) Annex A hereto on the cover, (b) Annex B hereto in the “Exchange Offer Procedures”
section and the “Purpose of the Exchange Offer” section, and (c) Annex C hereto in the “Plan of Distribution” section of such prospectus in connection with a sale of any such Exchange Securities received by such
Exchanging Dealer pursuant to the Registered Exchange Offer and (ii) an Initial Purchaser that elects to sell Exchange Securities acquired in exchange for Securities constituting any portion of an unsold allotment is required to deliver a
prospectus containing the information required by Items 507 or 508 of Regulation S-K under the Securities Act, as applicable, in connection with such sale. 
 The Company shall use its reasonable best efforts to keep the Exchange Offer Registration Statement effective and to amend and supplement the prospectus contained therein, in order to permit such
prospectus to be lawfully delivered by all persons subject to the prospectus delivery requirements of the Securities Act for such period of time as such persons must comply with such requirements in order to resell the Exchange Securities; provided,
however, that (i) in the case where such prospectus and any amendment 

  
 2 

 
or supplement thereto must be delivered by an Exchanging Dealer or an Initial Purchaser, such period shall be the lesser of 180 days and the date on which all Exchanging Dealers and the Initial
Purchasers have sold all Exchange Securities held by them (unless such period is extended pursuant to Section 3(j) below) and (ii) the Company shall make such prospectus and any amendment or supplement thereto, available to any
broker-dealer for use in connection with any resale of any Exchange Securities for a period of not less than 90 days after the consummation of the Registered Exchange Offer (or such shorter period which such persons are required by applicable law to
deliver such prospectus). 
 If, upon consummation of the Registered Exchange Offer, any Initial Purchaser holds Initial
Securities acquired by it as part of its initial distribution, the Company, simultaneously with the delivery of the Exchange Securities pursuant to the Registered Exchange Offer, shall issue and deliver to such Initial Purchaser upon the written
request of such Initial Purchaser, in exchange (the “Private Exchange”) for the Initial Securities held by such Initial Purchaser, a like principal amount of debt securities of the Company issued under the Indenture and identical in all
material respects (including the existence of restrictions on transfer under the Securities Act and the securities laws of the several states of the United States, but excluding the payment of liquidated damages as described in Section 6
hereof) to the Initial Securities (the “Private Exchange Securities”). The Initial Securities, the Exchange Securities and the Private Exchange Securities are herein collectively called the “Securities”. 

In connection with the Registered Exchange Offer, the Company shall: 

(a) mail to each Holder a copy of the prospectus forming part of the Exchange Offer Registration Statement, together
with an appropriate letter of transmittal and related documents; 
 (b) keep the Registered Exchange Offer
open for not less than 30 days (or longer, if required by applicable law) after the date notice thereof is mailed to the Holders; 
 (c) utilize the services of a depositary for the Registered Exchange Offer with an address in the Borough of Manhattan, The City of New York, which may be the Trustee or an affiliate of the Trustee;

 (d) permit Holders to withdraw tendered Securities at any time prior to the close of business, New York
time, on the last business day on which the Registered Exchange Offer shall remain open; and 

(e) otherwise comply with all applicable laws. 

As soon as practicable after the close of the Registered Exchange Offer or the Private Exchange, as the case may be, the Company shall:

 (x) accept for exchange all the Securities validly tendered and not withdrawn pursuant to the Registered
Exchange Offer and the Private Exchange; 
 (y) deliver to the Trustee for cancellation all the Initial
Securities so accepted for exchange; and 
 (z) cause the Trustee to authenticate and deliver promptly to
each Holder of the Initial Securities, Exchange Securities or Private Exchange Securities, as the case may be, equal in principal amount to the Initial Securities of such Holder so accepted for exchange. 

  
 3 

 The Indenture will provide that the Exchange Securities will not be subject to the transfer
restrictions set forth in the Indenture and that all the Securities will vote and consent together on all matters as one class and that none of the Securities will have the right to vote or consent as a class separate from one another on any matter.

 Interest on each Exchange Security and Private Exchange Security issued pursuant to the Registered Exchange Offer and in the
Private Exchange will accrue from the last interest payment date on which interest was paid on the Initial Securities surrendered in exchange therefor or, if no interest has been paid on the Initial Securities, from the Issue Date. 

Each Holder participating in the Registered Exchange Offer shall be required to represent to the Company that at the time of the
consummation of the Registered Exchange Offer (i) any Exchange Securities received by such Holder will be acquired in the ordinary course of business, (ii) such Holder will have no arrangements or understanding with any person to
participate in the distribution of the Securities or the Exchange Securities within the meaning of the Securities Act, (iii) such Holder is not an “affiliate,” as defined in Rule 405 of the Securities Act, of the Company or if it is
an affiliate, such Holder will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable, (iv) if such Holder is not a broker-dealer, that it is not engaged in, and does not intend to
engage in, the distribution of the Exchange Securities and (v) if such Holder is a broker-dealer, that it will receive Exchange Securities for its own account in exchange for Initial Securities that were acquired as a result of market-making
activities or other trading activities and that it will be required to acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. 
 Notwithstanding any other provisions hereof, the Company will ensure that (i) any Exchange Offer Registration Statement and any amendment thereto and any prospectus forming part thereof and any
supplement thereto complies in all material respects with the Securities Act and the rules and regulations thereunder, (ii) any Exchange Offer Registration Statement and any amendment thereto does not, when it becomes effective, contain an
untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading and (iii) any prospectus forming part of any Exchange Offer Registration Statement,
and any supplement to such prospectus, does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances
under which they were made, not misleading. 
 2. Shelf Registration. If, (i) because of any change in law or
in applicable interpretations thereof by the staff of the Commission, the Company is not permitted to effect a Registered Exchange Offer, as contemplated by Section 1 hereof, (ii) the Registered Exchange Offer is not consummated within 390
days of the Issue Date, (iii) any Initial Purchaser so requests with respect to the Initial Securities (or the Private Exchange Securities) not eligible to be exchanged for Exchange Securities in the Registered Exchange Offer and held by it
following consummation of the Registered Exchange Offer or (iv) any Holder (other than an Exchanging Dealer) is not eligible to participate in the Registered Exchange Offer or, in the case of any Holder (other than an Exchanging Dealer) that
participates in the Registered Exchange Offer, such Holder does not receive freely tradeable Exchange Securities on the date of the exchange, the Company shall take the following actions: 

(a) The Company shall, at its cost, as promptly as practicable (but in no event more than 30 days after so required
or requested pursuant to this Section 2) file with the Commission and thereafter shall use its reasonable best efforts to cause to be declared effective (unless it becomes 

  
 4 

 
effective automatically upon filing) a registration statement (the “Shelf Registration Statement” and, together with the Exchange Offer Registration Statement, a “Registration
Statement”) on an appropriate form under the Securities Act relating to the offer and sale of the Transfer Restricted Securities (as defined in Section 6 hereof) by the Holders thereof from time to time in accordance with the methods of
distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act (hereinafter, the “Shelf Registration”); provided, however, that no Holder (other than an Initial Purchaser) shall be entitled to have the
Securities held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by all the provisions of this Agreement applicable to such Holder. 

(b) The Company shall use its reasonable best efforts to keep the Shelf Registration Statement continuously effective
in order to permit the prospectus included therein to be lawfully delivered by the Holders of the relevant Securities, for a period of two years (or for such longer period if extended pursuant to Section 3(j) below) from the Issue Date or such
shorter period that will terminate when all the Securities covered by the Shelf Registration Statement (i) have been sold pursuant thereto or (ii) have been distributed to the public pursuant to Rule 144 under the Securities Act. The
Company shall be deemed not to have used its reasonable best efforts to keep the Shelf Registration Statement effective during the requisite period if it voluntarily takes any action that would result in Holders of Securities covered thereby not
being able to offer and sell such Securities during that period, unless such action is required by applicable law. 
 (c) Notwithstanding any other provisions of this Agreement to the contrary, the Company shall cause the Shelf Registration Statement and the related prospectus and any amendment or supplement
thereto, as of the effective date of the Shelf Registration Statement, amendment or supplement, (i) to comply in all material respects with the applicable requirements of the Securities Act and the rules and regulations of the Commission and
(ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not
misleading. 
 3. Registration Procedures. In connection with any Shelf Registration contemplated by Section 2
hereof and, to the extent applicable, any Registered Exchange Offer contemplated by Section 1 hereof, the following provisions shall apply: 
 (a) The Company shall (i) furnish to each Initial Purchaser, prior to the filing thereof with the Commission, a copy of the Registration Statement and each amendment thereof and each supplement,
if any, to the prospectus included therein and, in the event that an Initial Purchaser (with respect to any portion of an unsold allotment from the original offering) is participating in the Registered Exchange Offer or the Shelf Registration
Statement, the Company shall use its best efforts to reflect in each such document, when so filed with the Commission, such comments as such Initial Purchaser reasonably may propose; (ii) include the information set forth in Annex A
hereto on the cover, in Annex B hereto in the “Exchange Offer Procedures” section and the “Purpose of the Exchange Offer” section and in Annex C hereto in the “Plan of Distribution” section of the
prospectus forming a part of the Exchange Offer Registration Statement and include the information set forth in Annex D hereto in the Letter of Transmittal delivered pursuant to the Registered Exchange Offer; (iii) if requested by an
Initial Purchaser, include the information required by Items 507 or 508 of Regulation S-K under the Securities Act, as applicable, in the prospectus forming a part of the Exchange Offer Registration Statement; (iv) include within the prospectus
contained in the Exchange Offer Registration Statement a section entitled “Plan of 

  
 5 

 
Distribution,” reasonably acceptable to the Initial Purchasers, which shall contain a summary statement of the positions taken or policies made by the staff of the Commission with respect to
the potential “underwriter” status of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of Exchange Securities received by such
broker-dealer in the Registered Exchange Offer (a “Participating Broker-Dealer”), whether such positions or policies have been publicly disseminated by the staff of the Commission or such positions or policies, in the reasonable judgment
of the Initial Purchasers based upon advice of counsel (which may be in-house counsel), represent the prevailing views of the staff of the Commission; and (v) in the case of a Shelf Registration Statement, include in the prospectus included in
the Shelf Registration Statement (or, if permitted by Commission Rule 430B(b), in a prospectus supplement that becomes a part thereof pursuant to Commission Rule 430B(f)) that is delivered to any Holder pursuant to Section 3(d)
and (f), the names of the Holders, who propose to sell Securities pursuant to the Shelf Registration Statement, as selling securityholders. 
 (b) The Company shall give written notice to the Initial Purchasers, the Holders of the Securities and any Participating Broker-Dealer from whom the Company has received prior written notice that it
will be a Participating Broker-Dealer in the Registered Exchange Offer (which notice pursuant to clauses (ii)-(v) hereof shall be accompanied by an instruction to suspend the use of the prospectus until the requisite changes have been made):

 (i) when the Registration Statement or any amendment thereto has been filed with the Commission and when
the Registration Statement or any post-effective amendment thereto has become effective; 
 (ii) of any
request by the Commission for amendments or supplements to the Registration Statement or the prospectus included therein or for additional information; 
 (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose, of the issuance by the
Commission of a notification of objection to the use of the form on which the Registration Statement has been filed, and of the happening of any event that causes the Company to become an “ineligible issuer,” as defined in Commission
Rule 405. 
 (iv) of the receipt by the Company or its legal counsel of any notification with respect
to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and 
 (v) of the happening of any event that requires the Company to make changes in the Registration Statement or the prospectus in order that the Registration Statement or the prospectus do not contain
an untrue statement of a material fact nor omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus, in light of the circumstances under which they were made) not
misleading. 
 (c) The Company shall make every reasonable effort to obtain the withdrawal at the earliest
possible time, of any order suspending the effectiveness of the Registration Statement. 

  
 6 

 (d) To the extent not available on the SEC’s website at
www.sec.gov, the Company shall furnish to each Holder of Securities included within the coverage of the Shelf Registration, without charge, at least one copy of the Shelf Registration Statement and any post-effective amendment or supplement thereto,
including financial statements and schedules, and, if the Holder so requests in writing, all exhibits thereto (including those, if any, incorporated by reference). The Company shall not, without the prior consent of the Initial Purchasers, make any
offer relating to the Securities that would constitute a “free writing prospectus,” as defined in Commission Rule 405. 
 (e) To the extent not available on the SEC’s website at www.sec.gov, the Company shall deliver to each Exchanging Dealer and each Initial Purchaser, and to any other Holder who so requests,
without charge, at least one copy of the Exchange Offer Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if any Initial Purchaser or any such Holder requests, all exhibits thereto
(including those incorporated by reference). 
 (f) The Company shall, during the Shelf Registration Period,
deliver to each Holder of Securities included within the coverage of the Shelf Registration, without charge, as many copies of the prospectus (including each preliminary prospectus) included in the Shelf Registration Statement and any amendment or
supplement thereto as such person may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by each of the selling Holders of the Securities in
connection with the offering and sale of the Securities covered by the prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement. 

(g) The Company shall deliver to each Initial Purchaser, any Participating Broker-Dealer and such other persons
required to deliver a prospectus following the Registered Exchange Offer, without charge, as many copies of the final prospectus included in the Exchange Offer Registration Statement and any amendment or supplement thereto as such persons may
reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by any Initial Purchaser, if necessary, any Participating Broker-Dealer and such other persons
required to deliver a prospectus following the Registered Exchange Offer in connection with the offering and sale of the Exchange Securities covered by the prospectus, or any amendment or supplement thereto, included in such Exchange Offer
Registration Statement. 
 (h) Prior to any public offering of the Securities, pursuant to any Registration
Statement, the Company shall use its reasonable best efforts to register or qualify or cooperate with the Holders of the Securities included therein and their respective counsel in connection with the registration or qualification of the Securities
for offer and sale under the securities or “blue sky” laws of such states of the United States as any Holder of the Securities reasonably requests in writing and do any and all other acts or things necessary or advisable to enable the
offer and sale in such jurisdictions of the Securities covered by such Registration Statement; provided, however, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it is not then so
qualified or (ii) take any action which would subject it to general service of process or to taxation in any jurisdiction where it is not then so subject. 
 (i) The Company shall cooperate with the Holders of the Securities to facilitate the timely preparation and delivery of certificates representing the Securities to be sold pursuant to any
Registration Statement free of any restrictive legends and in such denominations and registered in such names as the Holders may request a reasonable period of time prior to sales of the Securities pursuant to such Registration Statement.

  
 7 

 (j) Upon the occurrence of any event contemplated by paragraphs
(ii) through (v) of Section 3(b) above during the period for which the Company is required to maintain an effective Registration Statement, the Company shall promptly prepare and file a post-effective amendment to the Registration
Statement or a supplement to the related prospectus and any other required document so that, as thereafter delivered to Holders of the Securities or purchasers of Securities, the prospectus will not contain an untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Initial Purchasers, the Holders of the
Securities and any known Participating Broker-Dealer in accordance with paragraphs (ii) through (v) of Section 3(b) above to suspend the use of the prospectus until the requisite changes to the prospectus have been made, then the
Initial Purchasers, the Holders of the Securities and any such Participating Broker-Dealers shall suspend use of such prospectus, and the period of effectiveness of the Shelf Registration Statement provided for in Section 2(b) above and the
Exchange Offer Registration Statement provided for in Section 1 above shall each be extended by the number of days from and including the date of the giving of such notice to and including the date when the Initial Purchasers, the Holders of
the Securities and any known Participating Broker-Dealer shall have received such amended or supplemented prospectus pursuant to this Section 3(j). During the period during which the Company is required to maintain an effective Shelf
Registration Statement pursuant to this Agreement, the Company will prior to the expiration of that Shelf Registration Statement file, and use its reasonable best efforts to cause to be declared effective (unless it becomes effective automatically
upon filing) within a period that avoids any interruption in the ability of Holders of Securities covered by the expiring Shelf Registration Statement to make registered dispositions, a new registration statement relating to the Securities, which
shall be deemed the “Shelf Registration Statement” for purposes of this Agreement. 
 (k) Not
later than the effective date of the applicable Registration Statement, the Company will provide a CUSIP number for the Initial Securities, the Exchange Securities or the Private Exchange Securities, as the case may be, and provide the applicable
trustee with printed certificates for the Initial Securities, the Exchange Securities or the Private Exchange Securities, as the case may be, in a form eligible for deposit with The Depository Trust Company. 

(l) The Company will comply with all rules and regulations of the Commission to the extent and so long as they are
applicable to the Registered Exchange Offer or the Shelf Registration and will make generally available to its security holders (or otherwise provide in accordance with Section 11(a) of the Securities Act) an earnings statement satisfying the
provisions of Section 11(a) of the Securities Act, no later than 45 days after the end of a 12-month period (or 90 days, if such period is a fiscal year) beginning with the first month of the Company’s first fiscal quarter commencing after
the effective date of the Registration Statement, which statement shall cover such 12-month period. 

(m) The Company shall cause the Indenture to be qualified under the Trust Indenture Act of 1939, as amended, in a
timely manner and containing such changes, if any, as shall be necessary for such qualification. In the event that such qualification would require the appointment of a new trustee under the Indenture, the Company shall appoint a new trustee
thereunder pursuant to the applicable provisions of the Indenture.

 (n) The Company may require each Holder of Securities to be sold
pursuant to the Shelf Registration Statement to furnish to the Company such information regarding the Holder and the distribution of the Securities as the Company may from time to time reasonably require for inclusion in the Shelf Registration
Statement, and the Company may exclude from such registration the Securities of any Holder that unreasonably fails to furnish such information within a reasonable time after receiving such request. 

(o) The Company shall enter into such customary agreements (including, if requested, an underwriting agreement in
customary form) and take all such other action, if any, as any Holder of the Securities shall reasonably request in order to facilitate the disposition of the Securities pursuant to any Shelf Registration. 

(p) In the case of any Shelf Registration, the Company shall (i) make reasonably available for inspection by the
Holders of the Securities, any underwriter participating in any disposition pursuant to the Shelf Registration Statement and any attorney, accountant or other agent retained by the Holders of the Securities or any such underwriter all relevant
financial and other records, pertinent corporate documents and properties of the Company and (ii) cause the Company’s officers, directors, employees, accountants and auditors to supply all relevant information reasonably requested by the
Holders of the Securities or any such underwriter, attorney, accountant or agent in connection with the Shelf Registration Statement, in each case, as shall be reasonably necessary to enable such persons, to conduct a reasonable investigation within
the meaning of Section 11 of the Securities Act; provided, however, that the foregoing inspection and information gathering shall be coordinated on behalf of the Initial Purchasers by you and on behalf of the other parties, by one counsel
designated by and on behalf of such other parties as described in Section 4 hereof; and provided, further, however, that any information that is designated in writing by the Company, in good faith, as confidential at the time of delivery of
such information shall be kept confidential by the Holders or such attorney or accountant, unless such disclosure is made in connection with a court proceeding or required by applicable law, or such information is or becomes available to the public
generally or through a third party without, to the knowledge of any recipient of confidential information, an accompanying obligation of confidentiality or is independently developed. 

(q) In the case of any Shelf Registration, the Company, if requested by any Holder of Securities covered thereby,
shall cause (i) its counsel to deliver an opinion and updates thereof relating to the Securities in customary form addressed to such Holders and the managing underwriters, if any, thereof and dated, in the case of the initial opinion, the
effective date of such Shelf Registration Statement (it being agreed that the matters to be covered by such opinion shall include, without limitation, the due incorporation and good standing of the Company and its subsidiaries; the qualification of
the Company and its subsidiaries to transact business as foreign corporations; the due authorization, execution and delivery of the relevant agreement of the type referred to in Section 3(o) hereof; the due authorization, execution,
authentication and issuance, and the validity and enforceability, of the applicable Securities; the absence of material legal or governmental proceedings involving the Company and its subsidiaries; the absence of governmental approvals required to
be obtained in connection with the Shelf Registration Statement, the offering and sale of the applicable Securities, or any agreement of the type referred to in Section 3(o) hereof; the compliance as to form of such Shelf Registration Statement
and any documents incorporated by reference therein and of the Indenture with the requirements of the Securities Act and the Trust Indenture Act, respectively; and (A) as of the date of the opinion and

  
 9 

 
as of the effective date of the Shelf Registration Statement or most recent post-effective amendment thereto, as the case may be, the absence from such Shelf Registration Statement and the
prospectus included therein, as then amended or supplemented, and from any documents incorporated by reference therein and (B) as of an applicable time identified by such Holders or managing underwriters, the absence from such prospectus taken
together with any other documents identified by such Holders or managing underwriters, in the case of (A) and (B), of an untrue statement of a material fact or the omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading (in the case of any such incorporated documents, in the light of the circumstances existing at the time that such documents were filed with the Commission under the Exchange Act); (ii) its
officers to execute and deliver all customary documents and certificates and updates thereof requested by any underwriters of the applicable Securities and (iii) its independent public accountants to provide to the selling Holders of the
applicable Securities and any underwriter therefor a comfort letter in customary form and covering matters of the type customarily covered in comfort letters in connection with primary underwritten offerings, subject to receipt of appropriate
documentation as contemplated, and only if permitted, by Statement of Auditing Standards No. 72. 

(r) In the case of the Registered Exchange Offer, if requested by any Initial Purchaser or any known Participating
Broker-Dealer, the Company shall cause (i) its counsel to deliver to such Initial Purchaser or such Participating Broker-Dealer a signed opinion in the form set forth in Section 7(d) of the Purchase Agreement with such changes as are
customary in connection with the preparation of a Registration Statement and (ii) its independent public accountants to deliver to such Initial Purchaser or such Participating Broker-Dealer comfort letters, in customary form, meeting the
requirements as to the substance thereof as set forth in Section 7(a) of the Purchase Agreement, with appropriate date changes. 
 (s) If a Registered Exchange Offer or a Private Exchange is to be consummated, upon delivery of the Initial Securities by Holders to the Company (or to such other Person as directed by the Company)
in exchange for the Exchange Securities or the Private Exchange Securities, as the case may be, the Company shall mark, or caused to be marked, on the Initial Securities so exchanged that such Initial Securities are being canceled in exchange for
the Exchange Securities or the Private Exchange Securities, as the case may be; in no event shall the Initial Securities be marked as paid or otherwise satisfied. 

(t) The Company will use its reasonable best efforts to if the Initial Securities have been rated prior to the
initial sale of such Initial Securities, confirm such ratings will apply to the Securities covered by a Registration Statement. 
 (u) In the event that any broker-dealer registered under the Exchange Act shall underwrite any Securities or participate as a member of an underwriting syndicate or selling group or “assist in
the distribution” (within the meaning of the Conduct Rules (the “Rules”) of the Financial Industry Regulatory Authority, Inc. (“FINRA”)) thereof, whether as a Holder of such Securities or as an underwriter, a placement or
sales agent or a broker or dealer in respect thereof, or otherwise, the Company will assist such broker-dealer in complying with the requirements of such Rules, including, without limitation, by (i) if such Rules, including Rule 2720, shall so
require, engaging a “qualified independent underwriter” (as defined in Rule 2720) to participate in the preparation of the Registration Statement relating to such Securities, to exercise usual standards of due diligence in respect thereto
and, if any portion of the offering contemplated by such Registration Statement is an underwritten offering or is made through a placement or sales 

  
 10 

 
agent, to recommend the yield of such Securities, (ii) indemnifying any such qualified independent underwriter to the extent of the indemnification of underwriters provided in Section 5
hereof and (iii) providing such information to such broker-dealer as may be required in order for such broker-dealer to comply with the requirements of the Rules. 

(v) The Company shall use its reasonable best efforts to take all other steps necessary to effect the registration of
the Securities covered by a Registration Statement contemplated hereby. 
 4. Registration Expenses. The Company
shall bear all fees and expenses incurred in connection with the performance of its obligations under Sections 1 through 3 hereof (including the reasonable fees and expenses, if any, of Davis Polk & Wardwell LLP, counsel for the Initial
Purchasers, incurred in connection with the Registered Exchange Offer), whether or not the Registered Exchange Offer or a Shelf Registration is filed or becomes effective, and, in the event of a Shelf Registration, shall bear or reimburse the
Holders of the Securities covered thereby for the reasonable fees and disbursements of one firm of counsel designated by the Holders of a majority in principal amount of the Initial Securities covered thereby to act as counsel for the Holders of the
Initial Securities in connection therewith. 
 5. Indemnification. (a) The Company agrees to indemnify and hold
harmless each Holder of the Securities, any Participating Broker-Dealer and each person, if any, who controls such Holder or such Participating Broker-Dealer within the meaning of the Securities Act or the Exchange Act (each Holder, any
Participating Broker-Dealer and such controlling persons are referred to collectively as the “Indemnified Parties”) from and against any losses, claims, damages or liabilities, joint or several, or any actions in respect thereof
(including, but not limited to, any losses, claims, damages, liabilities or actions relating to purchases and sales of the Securities) to which each Indemnified Party may become subject under the Securities Act, the Exchange Act or otherwise,
insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or prospectus or in any amendment or supplement
thereto or in any preliminary prospectus or “issuer free writing prospectus,” as defined in Commission Rule 433 (“Issuer FWP”), relating to a Shelf Registration, or arise out of, or are based upon, the omission or alleged
omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse, as incurred, the Indemnified Parties for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage, liability or action in respect thereof; provided, however, that (i) the Company shall not be liable in any such case to the extent that such loss, claim, damage or
liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus or
Issuer FWP relating to a Shelf Registration in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein and (ii) with
respect to any untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus relating to a Shelf Registration Statement, the indemnity agreement contained in this subsection (a) shall not inure to the
benefit of any Holder or Participating Broker-Dealer from whom the person asserting any such losses, claims, damages or liabilities purchased the Securities concerned, to the extent that a prospectus relating to such Securities was required to be
delivered (including through satisfaction of the conditions of Commission Rule 172) by such Holder or Participating Broker-Dealer under the Securities Act in connection with such purchase and any such loss, claim, damage or liability of such
Holder or Participating Broker-Dealer results from the fact that there was not conveyed to such person, at or prior to the time of the sale of such Securities to such person, an amended or supplemented prospectus or, if permitted by
Section 3(d), an Issuer FWP correcting such untrue statement or omission or alleged untrue statement or omission if the Company had previously furnished copies thereof to such Holder or 

  
 11 

 
Participating Broker-Dealer; provided further, however, that this indemnity agreement will be in addition to any liability which the Company may otherwise have to such Indemnified Party. The
Company shall also indemnify underwriters, their officers and directors and each person who controls such underwriters within the meaning of the Securities Act or the Exchange Act to the same extent as provided above with respect to the
indemnification of the Holders of the Securities if requested by such Holders. 
 (b) Each Holder of the Securities,
severally and not jointly, will indemnify and hold harmless the Company and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act from and against any losses, claims, damages or liabilities or any
actions in respect thereof, to which the Company or any such controlling person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus or Issuer FWP relating to a Shelf Registration,
or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or omission or alleged untrue
statement or omission was made in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein; and, subject to the limitation set
forth immediately preceding this clause, shall reimburse, as incurred, the Company for any legal or other expenses reasonably incurred by the Company or any such controlling person in connection with investigating or defending any loss, claim,
damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability which such Holder may otherwise have to the Company or any of its controlling persons. 

(c) Promptly after receipt by an indemnified party under this Section 5 of notice of the commencement of any action or
proceeding (including a governmental investigation), such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 5, notify the indemnifying party of the commencement thereof; but
the failure to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture
of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or
(b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish,
jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof the indemnifying party will not be liable to such indemnified party under this Section 5 for any legal
or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof. No indemnifying party shall, without the prior written consent of the indemnified party, effect
any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an
unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action, and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf
of any indemnified party. 

  
 12 

 (d) If the indemnification provided for in this Section 5 is unavailable or
insufficient to hold harmless an indemnified party under subsections (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the
indemnified party on the other from the exchange of the Securities, pursuant to the Registered Exchange Offer, or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or
omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable considerations. The relative fault of the parties shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or such Holder or such other indemnified party, as the case
may be, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or
liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is
the subject of this subsection (d). Notwithstanding any other provision of this Section 5(d), the Holders of the Securities shall not be required to contribute any amount in excess of the amount by which the net proceeds received by such
Holders from the sale of the Securities pursuant to a Registration Statement exceeds the amount of damages which such Holders have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.
No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this
paragraph (d), each person, if any, who controls such indemnified party within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such indemnified party and each person, if any, who controls the
Company within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as the Company. 

(e) The agreements contained in this Section 5 shall survive the sale of the Securities pursuant to a Registration Statement
and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any indemnified party. 
 6. Additional Interest Under Certain Circumstances. (a) Additional interest (the “Additional Interest”) with respect to the Initial Securities shall be assessed as follows if
any of the following events occur (each such event in clauses (i) through (iii) below a “Registration Default”: 
 (i) If 180 days after the Issuer Date (or if the 180th day is not a business day, the first business day thereafter), neither the Exchange Offer Registration Statement nor a Shelf Registration Statement has been filed with the Commission; 

(ii) If by the date that is 360 days after the Issuer Date (or if the 360th day is not a business day, the first business day thereafter),
neither the Registered Exchange Offer is consummated nor, if required in lieu thereof, the Shelf Registration Statement is declared effective by the Commission; or 

  
 13 

 (iii) If after the Shelf Registration Statement is declared (or becomes
automatically) effective such Registration Statement or the related prospectus ceases to be effective or usable (except as permitted in paragraph (b)), and such failure to remain effective or usable continues for 30 consecutive days or exists
for more than an aggregate of 60 days in any 12-month period, in connection with resales of Transfer Restricted Securities during the periods specified herein because either (1) any event occurs as a result of which the related prospectus
forming part of such Registration Statement would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not
misleading, (2) it shall be necessary to amend such Registration Statement or supplement the related prospectus, to comply with the Securities Act or the Exchange Act or the respective rules thereunder, or (3) such Registration Statement
is a Shelf Registration Statement that has expired before a replacement Shelf Registration Statement has become effective. 
 Additional
Interest shall accrue on the Initial Securities over and above the interest set forth in the title of the Securities from and including the date on which any such Registration Default shall occur to but excluding the date on which all such
Registration Defaults have been cured, at a rate of 0.25% per annum of the principal amount of the Initial Securities for the first 90-day period immediately following the occurrence of a Registration Default, with such Additional Interest to
be increased by an additional 0.25% per annum with respect to each subsequent 90-day period in each case until the Registered Exchange Offer is completed or the Shelf Registration Statement is declared effective, up to a maximum Additional
Interest rate of 1.00% per annum. 
 (b) A Registration Default referred to in Section 6(a)(iii) hereof shall be
deemed not to have occurred and be continuing in relation to a Shelf Registration Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to such
Shelf Registration Statement to incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Holders to use the related prospectus
or (y) other material events, with respect to the Company that would need to be described in such Shelf Registration Statement or the related prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good
faith to amend or supplement such Shelf Registration Statement and related prospectus to describe such events; provided, however, that in any case if such Registration Default occurs for a continuous period in excess of 30 days, Additional Interest
shall be payable in accordance with the above paragraph from the day such Registration Default occurs until such Registration Default is cured. 
 (c) Any amounts of Additional Interest due pursuant to clause (i), (ii) or (iii) of Section 6(a) above will be payable in cash on the regular interest payment dates with respect to the
Initial Securities. The amount of Additional Interest will be determined by multiplying the applicable Additional Interest rate by the principal amount of the Initial Securities, multiplied by a fraction, the numerator of which is the number of days
such Additional Interest rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months), and the denominator of which is 360. 

(d) “Transfer Restricted Securities” means each Security until (i) the date on which such Transfer Restricted
Security has been exchanged by a person other than a broker-dealer for a freely transferable Exchange Security in the Registered Exchange Offer, (ii) following the exchange by a broker-dealer in the Registered Exchange Offer of a Initial
Security for an Exchange Note, the date on which such Exchange Note is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of the prospectus contained in the Exchange Offer Registration Statement,
(iii) the date on which such Initial Security has been effectively registered under the Securities Act and disposed of in accordance with 

  
 14 

 
the Shelf Registration Statement and (iv) the earliest date that is no less than two years after the Issue Date and on which all such Securities (except for Securities held by an affiliate
of the Company) are no longer subject to any restrictions on transfer under the Securities Act including those pursuant to Rule 144. 
 (e) Notwithstanding the foregoing in this Section 6: (1) the amount of Additional Interest payable shall not increase because more than one Registration Default has occurred and is pending, and
a Holder of a Transfer Restricted Securities who is not entitled to the benefits of the Shelf Registration Statement (i.e., such Holder has not elected to furnish information to the Company in accordance with Section 3(n) hereof) shall not be
entitled to Additional Interest with respect to a Shelf Registration Default; and (2) no Holder who (x) was eligible to exchange such Holder’s outstanding Securities at the time the Exchange Offer was pending and consummated and
(y) failed to validly tender such Securities for exchange pursuant to the Exchange Offer shall be entitled to receive any Additional Interest that would otherwise accrue subsequent to the date the Exchange Offer is consummated. 

7. Rules 144 and 144A. The Company shall use its reasonable best efforts to file the reports required to be filed by it
under the Securities Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file such reports, it will, upon the request of any Holder of Initial Securities, make publicly available other information so long
as necessary to permit sales of their securities pursuant to Rules 144 and 144A. The Company covenants that it will take such further action as any Holder of Initial Securities may reasonably request, all to the extent required from time to
time to enable such Holder to sell Initial Securities without registration under the Securities Act within the limitation of the exemptions provided by Rules 144 and 144A (including the requirements of Rule 144A(d)(4)). The Company will
provide a copy of this Agreement to prospective purchasers of Initial Securities identified to the Company by the Initial Purchasers upon request. Upon the request of any Holder of Initial Securities, the Company shall deliver to such Holder a
written statement as to whether it has complied with such requirements. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of its securities pursuant to the Exchange Act. 

8. Underwritten Registrations. Notwithstanding anything herein to the contrary, no Securities covered by a Shelf
Registration Statement may be sold in an underwritten offering under the Shelf Registration Statement without the prior written consent of the Company. 
 If any of the Transfer Restricted Securities covered by any Shelf Registration are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will
administer the offering (“Managing Underwriters”) will be selected by the Holders of a majority in aggregate principal amount of such Transfer Restricted Securities to be included in such offering, subject to the Company’s consent
(which shall not be unreasonably withheld or delayed). 
 No person may participate in any underwritten registration hereunder
unless such person (i) agrees to sell such person’s Transfer Restricted Securities on the basis reasonably provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and
(ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. 

9. Miscellaneous. 
 (a) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be
given, except by the Company and the written consent of the Holders of a majority in principal amount of the Securities affected by such amendment, modification, supplement, waiver or consents.

 ANNEX A 
 Each broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange
Securities. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial Securities where such Initial Securities were acquired by such broker-dealer as a
result of market-making activities or other trading activities. The Company has agreed that, for a period of 180 days after the Expiration Date (as defined herein), it will make this Prospectus available to any broker-dealer for use in connection
with any such resale. See “Plan of Distribution.” 

 ANNEX B 
 Each broker-dealer that receives Exchange Securities for its own account in exchange for Securities, where such Initial Securities were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. See “Plan of Distribution.” 

 ANNEX C 
 PLAN OF DISTRIBUTION 
 Each broker-dealer that receives Exchange Securities for
its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. This Prospectus, as it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with resales of Exchange Securities received in exchange for Initial Securities where such Initial Securities were acquired as a result of market-making activities or other trading activities. The Company has agreed that,
for a period of 180 days after the Expiration Date, it will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition, until [ ], 20[ ], all dealers effecting
transactions in the Exchange Securities, whether or not participating in this Exchange Offer, may be required to deliver a prospectus. (1) 
 The Company will not receive any proceeds from any sale of Exchange Securities by broker-dealers. Exchange Securities received by broker-dealers for their own account pursuant to the Exchange Offer may be
sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the Exchange Securities or a combination of such methods of resale, at market prices prevailing at the
time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions
from any such broker-dealer or the purchasers of any such Exchange Securities. Any broker-dealer that resells Exchange Securities that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates
in a distribution of such Exchange Securities may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit on any such resale of Exchange Securities and any commission or concessions received by any such
persons may be deemed to be underwriting compensation under the Securities Act. The Letter of Transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an
“underwriter” within the meaning of the Securities Act. 
 For a period of 180 days after the Expiration Date the
Company will promptly send additional copies of this Prospectus and any amendment or supplement to this Prospectus to any broker-dealer that requests such documents in the Letter of Transmittal. The Company has agreed to pay all expenses incident to
the Exchange Offer (including the expenses of one counsel for the Holders of the Securities) other than commissions or concessions of any brokers or dealers and will indemnify the Holders of the Securities (including any broker-dealers) against
certain liabilities, including liabilities under the Securities Act.
