 INDENTURE, dated as of April 23, 2010, among ATP Oil & Gas Corporation, a
Texas corporation (the “Issuer”), and The Bank of New York Mellon Trust Company, N.A., as trustee (in such capacity, the “Trustee”) and as collateral agent (in such capacity, the “Collateral Agent”).

 The Issuer has duly authorized the creation of an issue of 11.875% Senior Second Lien Notes due 2015 (the
“Notes”) and, to provide therefor, the Issuer has 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. 

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

 -2- 

 

 (1) any properties or assets (i) to be used or that will be useful by
the Issuer or a Restricted Subsidiary in the Oil and Gas Business or (ii) that replace properties or assets that were the subject of an Asset Disposition; 

(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 $1,500,000,000 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 since such year end due to exploration, development or exploitation, production or other activities which would,

 -3- 

 

 
in accordance with standard industry practice, cause such revisions, in the case of clauses (A) and (B) calculated in accordance with SEC guidelines (utilizing the prices utilized in
such Person’s year-end reserve report), 
 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 
 (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 pretax basis and substantially in accordance
with SEC guidelines in the case of clauses (C) and (D) (utilizing the prices utilized in such Person’s year-end reserve report), 

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; provided, that, if no such appraisal has been 

 -4- 

 

 
performed the Issuer shall not be required to obtain such an appraisal and only clause (a)(iv)(A) of this definition shall apply; 

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 annual or quarterly balance sheet (to the extent not deducted in calculating Net Working Capital of such Person in accordance with clause (a)(iii) above of this definition); 

(iii) to the extent included in (a)(i) above, the discounted future net revenues, calculated in accordance with SEC
guidelines (utilizing the prices 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); 

(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); and 

(v) the present value of any overriding royalty interests in the form of net profits interests which are recorded as
liabilities on the Issuer’s most recent balance sheet included in its annual or quarterly financial statements. 
 If the
Issuer changes its method of accounting from the successful efforts method of accounting to the full cost or a similar method, “Adjusted Consolidated Net Tangible Assets” will continue to be calculated as if the Issuer were still using the
successful efforts 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 Per- 

 -5- 

 

 son 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 present value at such Redemption Date of (i) the Redemption Price of such Note at May 1, 2013 (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 to, but not including, such Redemption Date) due on such Note through May 1, 2013,
computed using a discount rate equal to the Treasury Rate as of such Redemption Date plus 50 basis points; over 

(b) the principal amount of such Note. 

“Applicable Procedures” means, with respect to any transfer or exchange of or for beneficial interests in any Global
Note, the rules and procedures of the Depository, Euroclear and/or Clearstream that apply to such transfer or exchange. 

“Asset Disposition” means any direct or indirect sale, lease (other than an operating lease entered into in the ordinary
course of the Oil and Gas Business), transfer, issuance or other disposition, or a series of related sales, leases, transfers, issuances or dispositions that are part of a common plan, of (A) shares of Capital Stock of a Subsidiary (other than

 -12-

remains outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness, Consolidated EBITDAX and Consolidated Interest Expense for such period
will be 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 shorter period for which such facility was outstanding or (ii) if such facility was created after the end of such four fiscal quarters, the average daily balance of such Indebtedness during the period from the date of creation of such

(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 EBITDAX 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 has 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 EBITDAX for such period will be reduced by an amount equal to the Consolidated EBITDAX (if positive) directly
attributable to the assets which are the subject of such Asset Disposition for such period or increased by an amount equal to the Consolidated EBITDAX (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

 -13-

thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition or contribution 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 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 EBITDAX 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 provided that such Officer may in his or her discretion
include any reasonably identifiable and factually supportable pro forma changes to Consolidated EBITDAX, including any pro forma expenses and cost reductions, that have occurred or in the judgment of such Officer are reasonably expected to occur
within 12 months of the date of the applicable transaction to the extent that such expense or cost reduction or any other operating improvements could then be reflected properly in pro forma financial statements prepared in accordance with
Regulation S-X under the Securities Act or any other regulation or policy of the SEC. 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 Indebt- 

 -14- 

 

 
edness 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.

Restricted Subsidiary of a Person will be added to Consolidated Net Income to compute Consolidated EBITDAX of such Person only to the extent (and in the same proportion) that the net income (loss) of such Restricted Subsidiary was included in

has net income for such period included in Consolidated Net Income, only if a corresponding amount would be permitted at the date of determination to be dividended to the Issuer by such Restricted Subsidiary without prior approval (that has not been

 (6) costs associated with Interest Rate Agreements (including amortization of fees);
provided, however, that if Interest Rate Agreements result in net benefits rather than costs, such 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 the Issuer and its Restricted
Subsidiaries that was capitalized during such period; and 
 (8) all dividends paid or payable in cash, Cash

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

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, 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 Is-

 -59- 

 

 
suer 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

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,

(i) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Restricted Global Note
may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Note in accordance with the transfer restrictions set forth in the Private Placement Legend; provided, however,
that 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

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

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

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.

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 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 an Authentication Order pursuant to Section 2.2, definitive Notes in exchange for temporary Notes.

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 it has paid
or delivered to the Trustee for cancellation. If the Issuer shall acquire any of the Notes, such acquisition shall 

 -73- 

 

 
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. Reserved. 

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

REDEMPTION 

SECTION 3.1. Notices to Trustee. 

If the Issuer elects to redeem Notes pursuant to Paragraph 5 of the Notes, it 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 at least 45 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 will be made by the Trustee either in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not then
listed or admitted to trading on a national securities exchange, in the case of Notes represented by Global Notes, by lot (or other procedures of the DTC), and, in the case of Notes represented by Definitive Notes, on a pro rata basis. No Notes of a
principal amount of $2,000 or less shall be redeemed in part. 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, interest will cease to accrue on Notes or portions thereof
called for redemption as long as the Issuer shall have previously deposited with the Paying Agent for the Notes funds in satisfaction of the applicable redemption price pursuant to this Indenture.

time, or from time to time, prior to May 1, 2013, the Issuer may, at its option, use all or a portion of the Net Cash Proceeds of one or more Equity Offerings to redeem up to 35% of the aggregate principal amount of the Notes (including any
Additional Notes) issued under this Indenture at a Redemption Price equal to 111.875% of the aggregate principal amount of the Notes to be redeemed, plus unpaid accrued interest thereon to the date of redemption; provided, that: (1) at

time prior to May 1, 2013 at the option of the Issuer at a Redemption Price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest to, 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 five 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: 

 -78- 

 

 (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 only remaining right of the Holders of such Notes is to receive payment of the Redemption Price plus unpaid accrued interest as of
the Redemption Date, if any, upon surrender to the Paying Agent of the Notes redeemed; 
 (7) if any Note is
being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the Redemption Date, and upon surrender of such Note, a new Note or Notes in the aggregate principal amount equal to the unredeemed portion
thereof will be issued; and 
 (8) if fewer than all the Notes are to be redeemed, the identification of the
particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial redemption.

Paying Agent, such Notes called for redemption shall be paid at the Redemption Price plus accrued and unpaid interest 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 rele-

 -79- 

 

 
vant 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 accrued and unpaid interest on 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. 

Upon surrender of a Note that is to be redeemed in part, the Trustee shall authenticate for the Holder a new Note or Notes equal in

surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 11.2. 
 SECTION
4.3. Organizational Existence. 
 Except as otherwise permitted by Article V, the Issuer shall do or cause
to be done, at its own cost and expense, all things necessary to preserve and keep in full force and effect its organizational existence and the organizational existence of each of its Restricted Subsidiaries in accordance with the respective
organizational documents of each such Restricted Subsidiary and the material rights (charter and statutory) and franchises of the Issuer and each such Restricted Subsidiary; provided, however, that the Issuer shall not be required to
preserve, with respect to itself, any material right or franchise and, with respect to any of its Restricted Subsidiaries, any such existence, material right or franchise, if the Board of Directors of the Issuer shall determine in good faith that
the preservation thereof is no longer desirable in the conduct of the business of the Issuer and its Subsidiaries, taken as a whole.

The Issuer shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (i) all material

 -81- 

 

 
any of the Restricted Subsidiaries from discontinuing the operation and maintenance of any of its properties, if such discontinuance is (i) in the ordinary course of business pursuant to
customary business terms or (ii) in the good faith judgment of the respective Boards of Directors or other governing body of the Issuer or Restricted Subsidiary, as the case may be, desirable in the conduct of their respective businesses and is
not disadvantageous in any material respect to the Holders. 
 (b) The Issuer shall provide or cause to be provided, for itself
and each of the Restricted Subsidiaries, insurance (including 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, for companies similarly situated in the industry. 
 SECTION 4.6.

 (a) The Issuer and each Subsidiary Guarantor (to the extent
that such Subsidiary Guarantor is so required under the TIA) shall deliver to the Trustee, within 120 days after the end of each of its fiscal years, an Officer’s Certificate (provided, however, that one of the signatories to each
such Officer’s Certificate must state that he or she is the Issuer’s principal executive officer, principal financial officer or principal accounting officer), as to such Officer’s knowledge, without independent investigation, of the

audit examination has included a review of the terms of this 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. 

(c) (i) If any Default or Event of Default has occurred and is continuing or (ii) if any Holder seeks to exercise any remedy under

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. 
 SECTION 4.8. Reports to
Holders. 
 (a) Whether or not the Issuer is subject to the reporting requirements of Section 13 or

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 an 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

non-accelerated filer.

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

 -83- 

 

 
of Notes as required by this Section 4.8 if it has filed such reports with the SEC via the EDGAR filing system and such reports are publicly available. 

(c) Notwithstanding the foregoing, such requirements shall be deemed satisfied prior to the commencement of the 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. 
 (d) The availability of the
foregoing materials on the SEC’s website or on the Issuer’s website shall be deemed to satisfy the foregoing delivery obligations. 

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 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 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. 
 SECTION 4.10. Limitation on Restricted Payments.

 The Issuer will not, and will not permit any of its Restricted Subsidiaries, directly or indirectly, to:

(2) purchase, redeem, defease, retire or otherwise acquire for value any Capital Stock of the Issuer or any direct or
indirect parent of the Issuer held by Persons other than the Issuer or a Restricted Subsidiary (other than in exchange for Capital Stock of the Issuer (other than Disqualified Stock));

defeasance or other acquisition or retirement); or 
 (4) make any Restricted Investment in any Person

 (each of the foregoing actions set forth in clauses (1) through (4) shall be referred to herein as a “Restricted

a Default shall have occurred and be continuing (or would result therefrom); 
 (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

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 

 -85- 

 

 
or securities other than cash (including Capital Stock of Persons engaged primarily in the Oil and Gas Business or assets used in the Oil and Gas Business), in each case received by the Issuer
from the issue or sale of its Capital Stock (other than Disqualified Stock) or other capital contributions subsequent to the Issue Date (other than Net Cash Proceeds received from an issuance or sale of such Capital Stock to (x) management,

 (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 Wholly-Owned 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), together with the net proceeds, if any, received by the Issuer or any of its Restricted Subsidiaries upon such conversion or exchange;

Unrestricted Subsidiaries as Restricted Subsidiaries (valued in each case as 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 

 -86- 

 

 
amount of Restricted Payments (but without duplication of any such amount) included in calculating cumulative Consolidated Net Income); and 

(C) the sale by the Issuer or any Restricted Subsidiary (other than to the Issuer or a Restricted Subsidiary) of all or a
portion of the Capital Stock of an Unrestricted Subsidiary or a distribution from an Unrestricted Subsidiary or a dividend from an Unrestricted Subsidiary (whether any such distribution or dividend is made with proceeds from the issuance by such

 Notwithstanding the foregoing, the provisions of the preceding
paragraph will not prohibit: 
 (1) any Restricted Payment made by exchange for, or out of the proceeds of the
substantially concurrent sale of, Capital Stock of the Issuer (other than Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary or an employee stock ownership plan or similar trust to the extent such sale to an employee
stock ownership plan or similar trust is financed by loans from or Guaranteed by the Issuer or any Restricted Subsidiary unless such loans have been repaid with cash on or prior to the date of determination) or a substantially concurrent cash
capital contribution received by the Issuer from its shareholders; provided, however, that (a) such Restricted Payment will be excluded from subsequent calculations of the amount of Restricted Payments and (b) the Net Cash Proceeds

Incurred pursuant Section 4.12; provided, however, that such purchase, repurchase, redemption, defeasance, acquisition or retirement will be excluded from subsequent calculations of the amount of Restricted Payments; 

 -87- 

 

 (4) dividends paid or distributions made within 60 days after the date of
declaration if at such date of declaration such dividend or distribution would have complied with this Section 4.10; provided, however, that such dividends and distributions will be included in subsequent calculations of the amount of
Restricted Payments; and provided further, however, that for purposes of clarification, this clause (4) shall not include cash payments in lieu of the issuance of fractional shares included in clause (9) below;

this clause (5) during any calendar year will not exceed $5.0 million in the aggregate; provided further, that such amount in any calendar year may be increased by an amount not to exceed (a) the cash proceeds received by the Issuer
from the sale of Capital Stock of the Issuer to then current or former members of management or directors of the Issuer and its Restricted Subsidiaries that occurs after the Issue Date (to the extent the cash proceeds from the sale of such Capital
Stock have not otherwise been applied to the payment of Restricted Payments by virtue of the clause (c) of the preceding paragraph), plus (b) the cash proceeds of key man life insurance policies received by the Issuer and its Restricted
Subsidiaries after the Issue Date, less (c) the amount of any Restricted Payments made pursuant to clauses (a) and (b) of this clause (5); provided further, however, that the amount of any such repurchase or redemption
under this clause (5) will be excluded in subsequent calculations of the amount of Restricted Payments and the proceeds received from any such sale will be excluded from clause (c)(ii) of the preceding paragraph. 

(6) repurchases, redemptions or other acquisitions or retirements for value of Capital Stock deemed to occur upon the
exercise of stock options, warrants, rights to acquire Capital Stock or other convertible securities if such Capital Stock represents a portion of the exercise or exchange price thereof, and any repurchases, redemptions or other acquisitions or
retirements for value of Capital Stock made in lieu of withholding taxes in connection with any exercise or exchange of warrants, options or rights to acquire Capital Stock; provided, however, that such repurchases will be excluded from
subsequent calculations of the amount of Restricted Payments; 
 (7) the purchase, repurchase, redemption,
defeasance or other acquisition or retirement for value of any Unsecured Indebtedness (i) at a purchase price not greater than 101% of the principal amount of such Unsecured Indebtedness in the

 -88- 

 

 
event of a Change of Control in accordance with provisions similar to Section 4.15 or (ii) at a purchase price not greater than 100% of the principal amount thereof in accordance with
provisions similar to Section 4.16; provided that, prior to or simultaneously with such purchase, repurchase, redemption, defeasance or other acquisition or retirement, the Issuer has made the Change of Control Offer or Asset Disposition
Offer, as applicable, as provided in such section with respect to the Notes and has completed the repurchase or redemption of all Notes validly tendered for payment in connection with such Change of Control Offer or Asset Disposition Offer;
provided, however, that such repurchases will be included in subsequent calculations of the amount of Restricted Payments pursuant to clause (c) of the preceding paragraph; 

(8) cash payments in lieu of the issuance of fractional shares; provided, however, that any payment pursuant to
this clause (8) shall be excluded in the calculation of the amount of Restricted Payments; 
 (9) the
declaration and payment of scheduled or accrued dividends to holders of any class of or series of Disqualified Stock (including Cash-Pay Preferred) of the Issuer or any of its Restricted Subsidiaries issued on or after the Issue Date in accordance
with Section 4.12; provided, however, that any payment pursuant to this clause (9) shall be excluded in the calculation of the amount of Restricted Payments; 

(10) so long as no Default or Event of Default has occurred and is continuing, the declaration and payment of scheduled or
accrued dividends to holders of any Specified Convertible Preferred to the extent such dividends are included in Consolidated Interest Expense; provided, however, that any payment pursuant to this clause (10) shall be included in
the calculation of the amount of Restricted Payments pursuant to clause (c) of the preceding paragraph; and 

(11) Restricted Payments in an amount not to exceed $30.0 million at any one time outstanding; provided, however,
that the amount of such Restricted Payments will be included in subsequent calculations of the amount of Restricted Payments pursuant to clause (c) of the preceding paragraph. 

The amount of all Restricted Payments (other than cash) shall be the fair market value on the date of such Restricted Payment of the
asset(s) or securities proposed to be paid, transferred or issued by the Issuer or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment. The fair market value of any cash Restricted Payment shall be its face amount and
the fair market value of any non-cash Restricted Payment shall be determined conclusively by the Board of Directors of the Issuer acting in good faith whose resolution with respect thereto shall be delivered to the Trustee, such determination to be
based upon an opinion or appraisal issued by an accounting, appraisal or investment banking firm of national standing if such fair market value is estimated in good faith by the Board of Directors of the Issuer to exceed $50.0 million. Not later
than the date of making any Re-

 -89- 

 

 
stricted Payment, the Issuer shall deliver to the Trustee an Officer’s Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations
required by Section 4.10 were computed, together with a copy of any fairness opinion or appraisal required by this Indenture. 

In the event that a Restricted Payment meets the criteria of more than one of the exceptions described in (1) through (11) above or
is entitled to be made pursuant to the first paragraph above, the Issuer shall, in its sole discretion, classify such Restricted Payment. 

As of the Issue Date, all of the Issuer’s Subsidiaries will be Restricted Subsidiaries, except for the Infrastructure Subsidiaries.
The Issuer will not permit any Unrestricted Subsidiary to become a Restricted Subsidiary except pursuant to the last sentence of the definition of “Unrestricted Subsidiary.” For purpose of designating any Restricted Subsidiary as an
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 (11) 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 Subsidiaries
will not be subject to any of the restrictive covenants set forth in this Indenture. 
 SECTION 4.11. Limitations on
Affiliate Transactions. 
 The Issuer will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, enter into, make, amend or conduct any transaction (including making a payment to, the purchase, sale, lease or exchange of any property or the rendering of any service), contract, agreement or understanding with or for the
benefit of any Affiliate of the Issuer (an “Affiliate Transaction”) unless: 
 (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 might reasonably have been 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 of the Issuer or such Restricted Subsidiary; 

(2) if such Affiliate Transaction involves an aggregate consideration in excess of $15.0 million, the terms of such
transaction have been approved by a majority of the disinterested members of the Board of Directors of the Issuer (and such majority determines that such Affiliate Transaction satisfies the criteria in clause (1) above); and 

 -90- 

 

 (3) if such Affiliate Transaction involves an aggregate consideration in
excess of $50.0 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 Investment or Restricted Payment permitted by this Indenture; 

(2) any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the
funding of, employment or severance agreements and other compensation arrangements, options to purchase securities of the Issuer, restricted stock plans, long-term incentive plans, stock appreciation rights plans, participation plans or similar
employee benefits plans and/or indemnity provided on behalf of directors, officers and employees approved by the Board of Directors of the Issuer; 

(3) loans or advances to employees, officers or directors in the ordinary course of business of the Issuer or any of its
Restricted Subsidiaries; 
 (4) advances to or reimbursements of employees for moving, entertainment and travel
expenses, drawing accounts and similar expenditures in the ordinary course of business of the Issuer or any of its Restricted Subsidiaries; 

(5) any transaction between the Issuer and a Restricted Subsidiary or between Restricted Subsidiaries and Guarantees
issued by the Issuer or a Restricted Subsidiary for the benefit of the Issuer or a Restricted Subsidiary, as the case may be, not otherwise prohibited by Section 4.12; 

(6) 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; 

(7) 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; 
 (8) indemnities of officers, directors and employees of the
Issuer or any of its Restricted Subsidiaries required or permitted by bylaw or statutory provisions and 

 -91- 

 

 
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; 

(9) the payment of reasonable compensation and fees paid to, and indemnity provided on behalf of, officers, directors or
employees of the Issuer or any Restricted Subsidiary; 
 (10) the performance of 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; 
 (11)
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 materially no less favorable to
the Issuer and its Restricted Subsidiaries than those that would have been obtained in a comparable transaction with an unrelated Person, 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; 

(12) transactions with a Person (other than an Unrestricted Subsidiary) that is an Affiliate of the Issuer solely because
the Issuer owns, directly or through a Restricted Subsidiary, an Equity Interest in such Person; and 
 (13)
pledges of Capital Stock of Unrestricted Subsidiaries of the Issuer for the benefit of lenders to Unrestricted Subsidiaries of the Issuer. 

In addition, with respect to any operating, management or other agreement entered into between the Issuer or any Restricted Subsidiary
and an Infrastructure Subsidiary at the time such Infrastructure Subsidiary is an Unrestricted Subsidiary, the terms of such agreement need only comply with clauses (1) and (2) of the first paragraph of this covenant. 

SECTION 4.12. Limitation on Incurrence of Indebtedness and 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 

 -92- 

 

 
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 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).

 The first paragraph of this Section 4.12 will not prohibit the Incurrence of the following Indebtedness: 

(1) Indebtedness of the Issuer Incurred pursuant to one or more Credit Facilities in an aggregate amount not to exceed the
greater of (a) $150.0 million or (b) an amount equal to 10% of the Issuer’s 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, in each case outstanding at any one time; 
 (2) Guarantees by the Issuer or Subsidiary
Guarantors of Indebtedness of the Issuer or a Subsidiary Guarantor, as the 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 of the Issuer or a Subsidiary Guarantor, then the related Guarantee shall be subordinated in right of payment to the Notes or the Subsidiary Guarantee to at least the same extent as the Indebtedness being Guaranteed, as the case may be;

 (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 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, (b) any
Indebtedness (other than the Indebtedness described in clauses (1), (2) and 4(a)) outstanding on the Issue Date and (c) any Refinancing Indebtedness Incurred in respect of any Indebtedness described in this clause (4) or clause
(5) or Incurred pursuant to the first paragraph of this Section 4.12; 
 (5) Indebtedness of a Person
that becomes a Restricted Subsidiary or is acquired by the Issuer or a Restricted Subsidiary or merged into the Issuer or a Restricted Subsidiary in accordance with this Indenture and outstanding on the date on

 -93- 

 

 
which such Person became a Restricted Subsidiary or was acquired by or was merged into the Issuer or such Restricted Subsidiary (other than Indebtedness Incurred (a) to provide all or any
portion of the 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
Obligations, Synthetic Lease Obligations, mortgage financings or purchase money obligations, in each case Incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvements or carrying costs of
property used in the business of 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 of all other Indebtedness incurred pursuant to this clause (6) and then outstanding, will not exceed $60.0 million at any time outstanding; 

(7) Permitted Acquisition Indebtedness; 

(8) Indebtedness Incurred in respect of (a) workers’ compensation claims, payment obligations in connection with
health or other types of social security benefits, unemployment or other insurance or self-insurance obligations, reclamation, statutory obligations, bankers’ acceptances, 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 or completion or performance guarantees or equipment leases, or other similar obligations in
the ordinary course of business or consistent with past practice (in the case of clauses (a) and (b) other than for an obligation for money borrowed); 

(9) Indebtedness, including Refinancing Indebtedness, Incurred by a Foreign Subsidiary in an aggregate amount not to
exceed 10% of such Foreign Subsidiary’s Adjusted Consolidated Net Tangible Assets at any time outstanding; 

 -94- 

 

 (10) Capital Stock (other than Disqualified Stock) of the Issuer or of any
of the Subsidiary Guarantors; 
 (11) Cash-Pay Preferred issued by the Issuer; provided, however,
that at the time of such issuance, the Issuer would have been able to Incur $1.00 of additional Indebtedness pursuant to the first paragraph of this covenant after giving effect to the Incurrence of such Cash Pay Preferred pursuant to this clause
(11); 
 (12) Indebtedness Incurred after the Issue Date by a wholly-owned Foreign Subsidiary in an aggregate
amount not to exceed $250.0 million at any time outstanding as vendor financing related to the construction of ATP Octabuoy drilling and production platform and an unsecured Guarantee thereof by the Issuer; provided, however, that such
Foreign Subsidiary ceasing to be a wholly-owned Subsidiary (other than directors’ qualifying shares) shall be deemed an Incurrence by the Issuer of such Guarantee that is not permitted by this clause (12); and 

(13) in addition to the items referred to in clauses (1) through (12) above, Indebtedness of the Issuer and its
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 (13) and then outstanding, will not at any time exceed the
greater of $50 million or 1.25% of the Issuer’s Adjusted Consolidated Net Tangible Assets, determined as of the date of Incurrence of such Indebtedness after giving effect to such Incurrence and 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 classify, reclassify or redivide all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.12; 

(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; 

 -95- 

 

 (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 

(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 Statement of Financial Accounting Standard No. 133) 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 

 -96- 

 

 
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. 
 This Indenture will not treat (1) unsecured Indebtedness as subordinated or junior to secured Indebtedness
merely because it is unsecured or (2) senior Indebtedness as subordinated or junior to any other senior Indebtedness merely because it has a junior priority with respect to the same collateral. 

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: 

 -97- 

 

 (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, the Security Documents and the Intercreditor Agreement in effect on such date but excluding the Senior Secured Credit Agreement; 

(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 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) with respect to any Foreign
Subsidiary, any encumbrance or restriction contained in the terms of any Indebtedness or any agreement pursuant to which such Indebtedness was Incurred if either (1) the encumbrance or restriction applies only in the event of a payment default
or a default with respect to a financial covenant in such Indebtedness or agreement or (2) the Issuer determines that any such encumbrance or restriction will not materially affect the Issuer’s ability to make principal or interest
payments on the Notes, as determined in good faith by the Board of Directors of the Issuer, whose determination shall be conclusive; 

(vi) 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) through (v) 

 -98- 

 

 
or clause (xii) of this paragraph or this clause (vi) or contained in any amendment, restatement, modification, renewal, supplemental, refunding, replacement or refinancing of an
agreement referred to in clauses (i) through (v) or clause (xii) of this paragraph or this clause (vi); provided 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 the agreements governing the Indebtedness being refunded, replaced or refinanced; 

(vii) 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 (including, without limitation, licenses of intellectual property) 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; 

(c) contained in Hedging Obligations permitted from time to time under this Indenture; 

(d) pursuant to customary provisions restricting dispositions of real property interests set forth in any reciprocal
easement agreements of the Issuer or any Restricted Subsidiary; 
 (e) restrictions on cash or other deposits
imposed by customers under contracts entered into in the ordinary course of business; or 
 (f) 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; 

 -99- 

 

 (viii) (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; 
 (ix) 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 a portion of 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; 
 (x) any customary encumbrances or restrictions
imposed pursuant to any agreement of the type described in the definition of “Permitted Business Investment”; 

(xi) encumbrances or restrictions arising or existing by reason of applicable law or any applicable rule, regulation or
order; 
 (xii) other Indebtedness of the Issuer or any of its Restricted Subsidiaries permitted to be Incurred
pursuant to an agreement entered into subsequent to the Issue Date in accordance with Section 4.12; provided that the provisions relating to such encumbrance or restriction contained in such Indebtedness are not materially less favorable
to the Issuer taken as a whole, as determined by the Board of Directors of the Issuer in good faith, than the provisions contained in the Senior Secured Credit Agreement and in this Indenture as in effect on the Issue Date; 

(xiii) the issuance of Preferred Stock by a Restricted Subsidiary or the payment of dividends thereon in accordance with
the terms thereof; provided that issuance of such Preferred Stock is permitted pursuant to Section 4.12 and the terms of such Preferred Stock do not expressly restrict the ability of a Restricted Subsidiary to pay dividends or make any
other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such Preferred Stock prior to paying any dividends or making any other distributions on such other Capital Stock); 

(xiv) supermajority voting requirements existing under corporate charters, bylaws, stockholders agreements and similar
documents and agreements; 
 (xv) restrictions on cash or other deposits or net worth imposed by customers under
contracts entered into in the ordinary course of business; and 
 (xvi) the Senior Secured Credit Agreement as in
effect as of the Issue Date, and any amendments, modifications, restatements, renewals, increases, supple-

 -100- 

 

 
ments, refundings, replacements or refinancings thereof; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or
refinancings are no more restrictive 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. Reserved. 

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 of such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount of the Notes plus accrued and unpaid interest, if
any, to but not including 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 (or at the Issuer’s option, after a definitive agreement is in place for a Change of
Control, prior to the occurrence of such 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, to but not including 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 such notice 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; 

 -101- 

 

 (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 notice at the address specified in the
notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date; and 

(6) 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 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 properly
tendered; 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 to each Holder of Notes properly tendered the Change of Control Payment for such Notes. 

In the event that Holders of not less than 95% of the aggregate principal amount of the outstanding Notes accept a Change of Control
Offer and the Issuer purchases all of the Notes held by such Holders, the Issuer will have the right, on not less than 30, nor more than 60, days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of
Control Offer described above, to redeem all of the Notes that remain outstanding following such purchase at a purchase price equal to the Change of Control payment price plus, to the extent not included in the Change of Control payment price,
unpaid accrued interest and premium, if any, on the Notes that remain outstanding, to, but not including, the date of redemption (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment
date). 
 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 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. 

 -102- 

 

 The Change of Control provisions described above will be applicable whether or not any other
provisions of this Indenture are applicable. 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 under such Change of Control Offer. 
 A Change of Control Offer may be made in advance of a Change
of Control, and conditioned upon the occurrence of a Change of Control, if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer. 

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 (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 

(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 

 -103- 

 

 
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 First-Lien Obligations of the Issuer under the Senior Secured Credit Agreement, any other Indebtedness of the Issuer or a Subsidiary Guarantor that is secured by a Lien permitted to be Incurred
under this Indenture or Indebtedness (other than Disqualified Stock) of any Wholly-Owned Subsidiary that is not a Subsidiary Guarantor; 

(b) to invest in Additional Assets; provided that to the extent that the assets disposed of in such Asset
Disposition were Collateral, such Additional Assets which would constitute Collateral are pledged as Collateral under the Security Documents with the Lien on such Collateral securing the Notes being of the same priority with respect to the Notes as
the Lien on the assets disposed of; or 
 (c) to make a combination of prepayment and investment permitted by the
foregoing clauses (a) through (b); 
 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 $20.0 million, the Issuer will be required to make an offer (“Asset Disposition Offer”) to (i) in the case of Net Available Cash from dispositions of assets constituting Collateral, all Holders of Notes and all holders
of Other Second-Lien Obligations if required by the terms thereof, and (ii) in the case of other Net Available Cash, all Holders of Notes and all holders of other 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”) in each case to purchase the maximum principal amount of Notes and any such Other Second-Lien Obligations or
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 was issued with significant original issue discount, 100% of the accreted value thereof) of the Notes and Other Second-Lien Obligations or Pari Passu Notes, as applicable, plus accrued and unpaid interest (or in respect of
such 

 -104- 

 

 
Other Second-Lien Obligations or Pari Passu Indebtedness, as applicable, such lesser price, if any, as may be provided for by the terms of such Indebtedness) to but not including 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 or the agreements governing the Other
Second-Lien Obligations or Pari Passu Notes, as applicable, in each case in minimum principal amount of $2,000 and integral multiples of $1,000 in excess of $2,000. If the aggregate principal amount of Notes surrendered by holders thereof and Other
Second-Lien Obligations or 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 Other Second-Lien Obligations or Pari Passu Notes, as applicable. To the extent that the aggregate amount of Notes and Other Second-Lien Obligations or 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 Other Second-Lien Obligations or 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 Other Second-Lien Obligations or 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 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 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 so validly
tendered pursuant to the Asset Disposition Offer, or if less than the Asset Disposition Offer Amount has been validly tendered, all Notes and Pari Passu Notes so validly tendered. 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,

 -105- 

 

 
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 the case may be, an amount equal to the purchase price of the Notes or Pari Passu Notes so validly tendered 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 Authentication Order in accordance with Section 2.2 hereof, 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. 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 or Cash
Equivalents: 
 (1) the assumption by the transferee of Indebtedness (other than Unsecured Indebtedness or
Disqualified Stock) of the Issuer or Indebtedness of a Restricted Subsidiary (other than Unsecured Indebtedness or Disqualified Stock of any Restricted Subsidiary that is a Subsidiary Guarantor) and the release of the Issuer or such Restricted
Subsidiary from all liability on such Indebtedness in connection with such Asset Disposition (or in lieu of such a release, the agreement of the acquirer or its parent company to indemnify and hold the Issuer or such Restricted Subsidiary harmless
from and against any loss, liability or cost in respect of such assumed Indebtedness; provided, however, that such indemnity is (i) from an indemnifying party (or its long term debt securities) with an Investment Grade Rating
(with no indication of a negative outlook or credit watch with negative implications, in any case, that contemplates such indemnifying party (or its long term debt securities) failing to have an Investment Grade Rating or (ii) accompanied by
the posting of a letter of credit (issued by a commercial bank that has an Investment Grade Rating) in favor of the Issuer or such Restricted Subsidiary for the full amount of the liability and for so long as the liability remains outstanding, in
which case the Issuer will, without further action, be deemed 

 -106- 

 

 
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 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. Reserved. 

SECTION 4.18. Limitation on Liens. 

The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, Incur or suffer to
exist (i) any Lien on any asset or property that is not Collateral of the Issuer or such Restricted Subsidiary securing Indebtedness unless the Notes are equally and ratably secured with (or on a senior basis to, in the case of obligations
subordinated in right of payment to the Notes) the obligations so secured or (ii) any Lien on any asset or property that is Collateral. 

The preceding paragraph shall not prohibit Permitted Liens nor shall it require the Issuer or any Restricted Subsidiary of the Issuer to
secure the Notes if the Lien consists of a Permitted Lien. Any Lien which is granted to secure the Notes or such Subsidiary Guarantee under clause (i) of the preceding paragraph (unless also granted pursuant to clause (ii) of the preceding
paragraph) shall be automatically released and discharged at the same time as the release of the Lien that gave rise to the obligation to secure the Notes or such Subsidiary Guarantee under such clause (i). 

 -107- 

 

 SECTION 4.19. 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 4.20.
Additional Subsidiary Guarantees. 
 The Issuer shall cause each Restricted Subsidiary, other than a
Foreign Subsidiary created or acquired by the Issuer or one or more of its Restricted Subsidiaries, to execute and deliver a Subsidiary Guarantee; provided 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. If required to execute and deliver a Subsidiary Guarantee pursuant to this paragraph, such transferee or acquired or other Restricted Subsidiary shall:

 (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 all of the Issuer’s obligations under the Notes and this Indenture on the terms set forth in this Indenture; 

(2) deliver to the Trustee an Opinion of Counsel that such supplemental indenture has been duly authorized, executed and
delivered by such Restricted Subsidiary and constitutes a legal, valid, binding and enforceable obligation of such Restricted Subsidiary. Thereafter, such Restricted Subsidiary shall be a Subsidiary Guarantor for all purposes of this Indenture; and

 (3) become a party to the Intercreditor Agreement and the Security Documents and shall take such actions as
are reasonably necessary or advisable to grant the Collateral Agent, for the benefit of the Holders of the Notes and the Trustee, a perfected Second-Priority Lien on any Collateral held by such Restricted Subsidiary, subject to Permitted Liens.

 ARTICLE V. 

SUCCESSOR CORPORATION 

SECTION 5.1. Merger, Consolidation and Sale of All or Substantially All 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 (determined on a consolidated basis) in one or more related transactions to, any Person, unless: 

(1) either (a) the Issuer shall be the surviving corporation or (b) the resulting, surviving or transferee
Person (the “Successor Issuer”) (x) will be a corporation, partnership, trust or limited liability company organized and existing under the laws of the United States of America, any State of the United States or the District of
Columbia and the Successor Issuer (if not the Issuer) and (y) will expressly assume, by supplemental indenture, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all the obligations of the Issuer under the
Notes, this Indenture, the Registration Rights Agreement, the Intercreditor Agreement and the Security Documents, and all such obligations shall remain in full force and effect and the Successor Issuer shall cause such amendments, supplements or
other instruments to be executed, filed and recorded in such jurisdictions as may be required by applicable law to preserve and protect the Lien on the Collateral pledged by or transferred to such Person, together with the financing statements and
comparable documents as may be required to perfect any security interests in such Collateral which may be perfected by the filing of a financing statement or a similar document under the UCC or other similar statute or regulation of the relevant
states or jurisdictions, in each case in a form reasonably satisfactory to the Trustee; 
 (2) immediately after
giving effect to such transaction and the assumption contemplated by clause (1)(b)(y) above (including, without limitation, giving effect to any Indebtedness incurred or anticipated to be incurred and any Lien granted in connection with or in
respect of the transaction), no Default shall have occurred and be continuing; 
 (3) immediately after giving
effect to such transaction and the assumption contemplated by clause (1)(b)(y) above (including, without limitation, giving effect to any Indebtedness incurred or anticipated to be incurred in connection with or in respect of such transaction)
and the application of any net proceeds therefrom, (A) the Issuer or the Successor Issuer would, on the date of such transaction, after giving pro forma effect thereto and to any related financing transactions as if the same had
oc-

curred at the beginning of the applicable four quarter period, be able to Incur at least an additional $1.00 of Indebtedness pursuant to the first paragraph of Section 4.12 or (B) the
Consolidated Coverage Ratio of the Issuer or the Successor Issuer, as the case may be, is equal to or greater than the Consolidated Coverage Ratio of the Issuer immediately before such transaction; 

(4) each Subsidiary Guarantor (unless it is the other party to the transactions above, in which case clause (1) shall
apply) shall have by supplemental indenture confirmed that its Subsidiary Guarantee shall apply to such Person’s obligations in respect of this Indenture and the Notes and its obligations under the Registration Rights Agreement, the
Intercreditor Agreement and the Security Documents (if applicable) shall continue to be in effect; and 
 (5) the
Issuer or the Successor Issuer, as the case may be, shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and, if a supplemental indenture and additional
Security Documents are required in connection with such transaction, such supplemental indenture and Security Documents comply with the applicable provisions of this Indenture and Security Documents and that all conditions precedent in this
Indenture relating to such transaction have been satisfied; provided, however, that such counsel may rely, as to matters of fact, on a certificate or certificates of officers of the Issuer. 

For purposes of this Section 5.1, the sale, lease, conveyance, assignment, transfer, or other disposition of all or substantially
all of the properties and assets of one or more Restricted Subsidiaries of the Issuer, which properties and assets, if held by the Issuer instead of such Restricted 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 Registration Rights Agreement, the Intercreditor Agreement and the Security Documents as if such Successor Issuer had been named in such; and its predecessor Issuer, except in the case of a lease of all or substantially all its assets, will be
released from the obligation to pay the principal of and interest on the Notes. 
 Notwithstanding the preceding clause (3),
(x) any Restricted Subsidiary may consolidate with, merge into or transfer all or part of its properties and assets to the Issuer and the Issuer may consolidate with, merge into or transfer all or part of its properties and assets to a
Wholly-Owned Subsidiary and (y) the Issuer may merge with an Affiliate incorporated solely for the purpose of reincorporating the Issuer in another jurisdiction; provided that, in the case of a Restricted Subsidiary that consolidates
with, merges into or transfers all or part 

 -110- 

 

 
of its properties and assets to the Issuer, the Issuer will not be required to comply with the preceding clause (5). 

In addition, the Issuer will not permit any Subsidiary Guarantor to consolidate with or merge with or into, and will not permit the
conveyance, transfer or lease of substantially all of the assets of any Subsidiary Guarantor to, any Person (other than the Issuer or another Subsidiary Guarantor) unless: 

(1) (a) the resulting, surviving or transferee Person will be a corporation, partnership, trust or limited liability
company organized and existing under the laws of the United States of America, any State of the United States or the District of Columbia and such Person (if not such Subsidiary Guarantor) will expressly assume, by supplemental indenture and (if
required) additional Security Documents, executed and delivered to the Trustee, all the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee and (b) immediately after giving effect to such transaction (and treating any
Indebtedness that becomes an obligation of the resulting, surviving or transferee Person or any Restricted Subsidiary as a result of such transaction as having been Incurred by such Person or such Restricted Subsidiary at the time of such
transaction), no Default shall have occurred and be continuing; or 
 (2) the transaction is made in compliance
with Section 4.16 and Section 12.4. 
 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 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; 

 -111- 

 

 (4) failure by the Issuer to comply for 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, 4.18, 4.19 or 4.20 above (in each case, other than a failure to purchase Notes which 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)); 
 (5) failure by the Issuer to
comply for 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 express maturity; 

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under
which there has been a payment default or the maturity of which has been so accelerated, aggregates $25.0 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; 

(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 $25.0 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; 

 -112- 

 

 (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; or 

(10) so long as the Security Documents have not been otherwise terminated in accordance with their terms and the
Collateral as a whole has not been released from the Lien of the Security Documents securing the Notes in accordance with the terms thereof, with respect to Collateral having a Fair Market Value in excess of $100.0 million, individually or in the
aggregate, (a) the security interest under any Security Document, at any time, ceases to be in full force and effect for any reason other than in accordance with the terms of this Indenture, the Security Documents and the Intercreditor
Agreement, (b) repudiation or disaffirmation of the Issuer or any Subsidiary Guarantor of its respective obligations under the Security Documents or (c) the determination in a judicial proceeding that the Security Documents are
unenforceable or invalid against the Issuer or any Subsidiary Guarantor for any reason. 
 However, a default under clauses (3), (4) and
(5) of this Section 6.1 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 specifying the default (and demanding that such default be remedied) 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) of Section 6.1) 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
any, accrued and unpaid interest, if any, on all the Notes to be due and payable. If an Event of Default described in clause (7) of Section 6.1 occurs and is continuing, the principal of, premium, if any, accrued and unpaid interest 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 or interest) and rescind any such acceleration with respect to the Notes and its consequences if (1) rescission 

 -113- 

 

 
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. 

Notwithstanding the foregoing, (a) if an Event of Default specified in clause (6) of Section 6.1 shall have occurred and
be continuing, such Event of Default and any consequential acceleration (to the extent not in violation of any applicable law) shall be automatically rescinded if (i) the Indebtedness that is the subject of such Event of Default has been repaid
or (ii) if the default relating to such Indebtedness is waived or cured and if such Indebtedness has been accelerated, then the holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness and (b) if an
Event of Default specified in clause (10) of Section 6.1 shall have occurred and be continuing, such Event of Default and any consequential acceleration (to the extent not in violation of any applicable law) shall be automatically
rescinded if the Lien on such Collateral (with appropriate priority) has been reinstated within 90 days. 
 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 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
clauses (1) or (2) of Section 6.1 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. 

 -114- 

 

 SECTION 6.5. Control by Majority. 

Holders of the Notes may not enforce this Indenture or the Notes except as provided in this Article VI and under the TIA. The Holders of
not less than a majority in aggregate principal amount of the 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, or the Intercreditor Agreement, (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 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 the Trustee 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 Holder has offered the Trustee security or indemnity satisfactory to the Trustee 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. 

 -115- 

 

 A Holder may not use this Indenture to prejudice the rights of any other Holders or to
obtain priority or preference over such 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 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, 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. 

 -116- 

 

 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) 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); 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 under the circumstances 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. 

 -118- 

 

 (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. 

(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 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 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 fur-

 -119- 

 

 
ther 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. 

(j) In no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any
kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 

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. 

 -120- 

 

 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 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. 

The Trustee may withhold the provision of any notice of a Default or Event of Default known to the Trustee 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 2010 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). 
 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. 

 -121- 

 

 
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, stockholders, 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 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 clause (7) of Section 6.1 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. 
 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: 

 -122- 

 

 (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 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. 

 -123- 

 

 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 million as set forth in its most recent published
annual report of condition. 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. 
 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 such notice references the Notes and the Indenture and, in the absence of such notice so delivered, the Trustee may
conclusively assume no Default exists. 

 -124- 

 

 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, and if in either case the Issuer pays all other sums payable under
this Indenture by the Issuer, then this Indenture, the Subsidiary Guarantees, the Security Documents and the Intercreditor Agreement shall, except for certain obligations, including those respecting the defeasance trust and obligations to register
the transfer or exchange of the Notes, to replace mutilated, destroyed, lost or stolen Notes and to maintain a Registrar and Paying Agent in respect of the Notes, cease to be of further effect and all Liens under the Security Documents will be
released; (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, this Indenture, the Subsidiary Guarantees and the Security Documents and cause the release of all Liens on the Collateral granted under the Security Documents (“Legal
Defeasance”). Such Legal Defeasance means that the Issuer shall be deemed to have paid and discharged the entire indebtedness represented by the outstanding Notes, and satisfied all of

 -125- 

 

 
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 under the Notes, this Indenture, the Subsidiary Guarantees and the Security Documents, cause the release of all Liens on the Collateral granted under the Security Documents, terminate its obligations
with respect to covenants contained in Sections 4.4, 4.5, 4.8 and 4.10 through 4.20 and Article V and the operation of clauses (6), (7) (with respect to Significant Subsidiaries), (8) or (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), (9) or
(10) 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 its obligations with respect to its Subsidiary Guarantee and all Liens on the Collateral will be released. 

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
Defeasance and will be subject to federal income tax on the same amounts, in the 

 -126- 

 

 
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 clauses (7) or (8) of Section 6.1 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. 

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 depos-

 -127- 

 

 
ited 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, 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, 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, if any, on or principal of any Notes because of the reinstatement
of its obligations, the Issuer shall be subrogated to 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. 

 -128- 

 

 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.

“Description of notes” in the preliminary offering memorandum dated April 13, 2010 relating to the offer and sale of the Notes to the extent that such provision in such “Description of notes” was intended to be a verbatim

 -130- 

 

 SECTION 9.2. With Consent of Holders. 

All other modifications and amendments of this Indenture, the Notes, the Intercreditor Agreement and the Security Documents 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). 
 Subject to certain exceptions, the
Intercreditor Agreement and the Security Documents may be amended with the consent of the Holders of a majority in principal amount of the Notes then outstanding (voting as one class) and any past default or noncompliance with any provisions in the
Intercreditor Agreement and the Security Documents may also be waived with the consent of the Holders of a majority in principal amount of the Notes then outstanding (voting as one class). Such amendments may not, without the consent of the Holders
of 75% in principal amount of the Notes then outstanding (voting as one class), release all or substantially all of the Collateral other than in accordance with this Indenture, the Intercreditor Agreement and the Security Documents. However, without
the consent of each Holder of an outstanding Note affected, no amendment may, among other things: 
 (1) reduce
the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 
 (2) reduce the
stated rate of or extend the stated time for payment of interest on any Note; 
 (3) reduce the principal of or
extend the Stated Maturity of any Note; 
 (4) reduce the amount payable upon 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, (other than Sections 4.15 and 4.16); 

(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 provisions which require each Holder’s consent or in the waiver provisions;

 -131- 

 

 (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 or the Security Documents 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. 
 No amendment of, or supplement or waiver to,
this Indenture, the Notes or the Security Documents (other than the Intercreditor Agreement) shall be permitted to be effected which is in violation of or inconsistent with the terms of the Intercreditor Agreement. No amendment of, or supplement to,
the Intercreditor Agreement shall be permitted to be effected without the consent of the First-Lien Collateral Agent and the Collateral Agent. 

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 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. 

 -132- 

 

 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 Trustee shall be
entitled to receive indemnity 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.

Holders may communicate pursuant to TIA § 312(b) with other Holders with respect to their rights under this Indenture or the
Notes. The Issuer, the Trustee, the Registrar and any other Person shall have the protection of TIA § 312(c).

performed by the Issuer, if any, provided for in this Indenture relating to the proposed action have been complied with (which counsel, as to factual matters, may rely on an Officer’s Certificate).

 (3) a statement that, in the opinion of such Person, he
has made such examination or investigation as is reasonably necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been complied with; and

The Paying Agent or Registrar may make reasonable rules for its functions.

which commercial banking institutions in New York, New York, or Houston, Texas or at such place of payment are authorized 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, THE SUBSIDIARY GUARANTEES, THE REGISTRATION RIGHTS AGREEMENT,
THE SECURITY DOCUMENTS (OTHER THAN THE MORTGAGES) AND THE INTERCREDITOR AGREEMENT 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

 -136- 

 

 
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, stockholder, member, partner,
manager or trustee of the Issuer or director, officer, employee, incorporator or stockholder of any Subsidiary Guarantor, as such, shall have any liability for any of the Issuer’s obligations under the Notes, the Subsidiary Guarantors’
obligations under the Subsidiary Guarantees or this Indenture or any claim based on, in respect of, by reason of, these obligations. Each Holder, by accepting a Note, waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.

respect for any reason, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions 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 

 -137- 

 

 
covenants, the fact that it would be permitted by an exception to, or otherwise be within the limitations of, another covenant shall not avoid the occurrence of a Default or an Event of Default
if such action is taken or condition exists. 
 SECTION 11.15. Waiver of Jury Trial. 

EACH OF THE ISSUER, THE SUBSIDIARY GUARANTORS AND THE TRUSTEE IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY
AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY. 

SECTION 11.16. U.S.A. Patriot Act. 

The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. Patriot Act, the Trustee, like all financial
institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account with the
Trustee. The parties to this Indenture agree that they will provide the Trustee with such information within their possession or control as it may reasonably request in order for the Trustee to satisfy the requirements of the U.S.A. Patriot Act.

 ARTICLE XII. 

SUBSIDIARY GUARANTEE OF NOTES 

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
fully guarantees, on a 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, 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 

 -138- 

 

 
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. 

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 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 stockholder, officer, director, employee, partner, incorporator,
member, manager or trustee, past, present or future, of any Subsidiary Guarantor, as such, shall have 

 -139- 

 

 
any personal liability under the Subsidiary Guarantees by reason of his, her or its status as such stockholder, officer, director, employee, partner, incorporator, member, manager or trustee.

 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. 
 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 D 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 the Issuer or a Re-

 -140- 

 

 
stricted 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 the Issuer or a Restricted Subsidiary), or (ii) upon the designation of a Subsidiary Guarantor as an Unrestricted Subsidiary in
accordance the requirements therefor set forth in the definition of “Unrestricted Subsidiary” 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. 
 (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 Officer’s 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 

 -141- 

 

 
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. 
 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 

 -142- 

 

 
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 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: 

 -143- 

 

 (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; 
 (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

 -144- 

 

 
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. 

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;

(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 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.

the same.

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, pow-

 -146- 

 

 
er 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.

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 and without giving

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.

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. 

 -147- 

 

 ARTICLE XIII. 

SECURITY 

SECTION 13.1. Collateral and Security Documents; Further Assurances;  

(a) The due and punctual payment of the principal of and interest on the Notes when and as the same shall be due and payable, whether on
an Interest Payment Date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of and interest on the Notes and performance of all other obligations of the Issuer and the Subsidiary Guarantors to
the Holders, the Trustee or the Collateral Agent according to the terms hereunder or thereunder, shall be secured as provided in the Security Documents. The Trustee and the Issuer hereby acknowledge and agree that the Collateral Agent holds the
Collateral in trust for the benefit of the Secured Parties, in each case pursuant to the terms of the Security Documents. Each Holder, by accepting a Note, consents and agrees to the terms of the Security Documents (including the provisions
providing for the possession, use, release and foreclosure of Collateral) as the same may be in effect or may be amended from time to time in accordance with their terms and this Indenture, and authorizes and directs the Collateral Agent to enter
into the Security Documents and to perform its obligations and exercise its rights thereunder in accordance therewith; provided, however, that if any of the provisions of the Security Documents limit, qualify or conflict with the
duties imposed by the provisions of the TIA, the TIA shall control. 
 (b) To the extent required under the Second-Lien Notes
Documents, the Issuer and the Subsidiary Guarantors shall execute any and all further documents, financing statements, agreements and instruments, and take all further action that may be required under applicable law, or that the Collateral Agent
may reasonably request, in order to grant, preserve, protect and perfect the validity and priority of the security interests and Liens created or intended to be created by the Security Documents in the Collateral, including, without limitation,
(i) prompt correction of any material defect which may hereafter be discovered in the title to the Mortgaged Property or in the execution and acknowledgment of the applicable Mortgage, any notes or any other document used in connection herewith
or at any time delivered to Issuer or any Subsidiary Guarantor in connection with any indebtedness owing to the Second-Lien Creditors, and (ii) prompt execution and delivery of all division or transfer orders that in the reasonable discretion
of the Collateral Agent are needed to transfer effectively the assigned proceeds of production from the Mortgaged Property to the Collateral Agent. In addition, to the extent required under the Second-Lien Notes Documents, from time to time, the
Issuer will reasonably promptly secure the obligations under the Second-Lien Notes Documents by pledging or creating, or causing to be pledged or created, perfected security interests and Liens with respect to the Collateral perfected to the extent
required by the Second-Lien Notes Documents. Such security interests and Liens will be created under the Security 

 -148- 

 

 
Documents and other security agreements and other instruments and documents in form and substance reasonably satisfactory to the Collateral Agent. 

(c) The Issuer agrees 

(1) in connection with the most recently completed Reserve Report delivered pursuant to Section 6.01 and 8.12 of the
Senior Secured Credit Agreement (or any similar provision of agreements refinancing, replacing, refunding, amending, restating or supplementing the Senior Secured Credit Agreement as in effect on the Issue Date); or 

(2) if no such provision exists, to certify in the form of an Officer’s Certificate to the Collateral Agent
semi-annually on or before April 1 and October 1 (and at the time of any release permitted under the Senior Secured Credit Agreement, after giving effect thereto concurrently such Officer’s Certificate to such effect to the First Lien
Collateral Agent) 
 that the Collateral includes Oil and Gas Properties subject to Mortgages over at least 80% of the total Recognized Value of
the Issuer’s and the Subsidiary Guarantors’ proved Oil and Gas Properties located in the United States and adjacent Federal waters as reflected in the most recent available annual or semi-annual Reserve Report on such reserves (the
“80% Requirement”) and that to the extent necessary, the Issuer and the Subsidiary Guarantors will cause to be delivered to the Collateral Agent (in form and substance reasonably satisfactory to the Collateral Agent) Mortgages or
amendments or supplements to prior Mortgages to satisfy the 80% Requirement; to the extent that any Mortgages for Oil and Gas Properties constituting Collateral are released after the date of the applicable Reserve Report and prior to delivery of
such Reserve Report or Officer’s Certificate, and are then assigned to Persons other than the Issuer and the Subsidiary Guarantors, any proved reserves attributable to such Oil and Gas Properties shall be deemed excluded from such Reserve
Report for the purpose of determining whether the 80% Requirement is met after giving effect to such release. 
 SECTION 13.2.
Recordings and Opinions. 
 (a) To the extent applicable, the Issuer will cause TIA § 313(b),
relating to reports, to be complied with. 
 (b) Any release of Collateral permitted by Section 13.3 hereof will be deemed
not to impair the Liens under this Indenture, the Notes, the Subsidiary Guarantees and the Security Documents in contravention thereof. 

 -149- 

 

 SECTION 13.3. Release of Collateral. 

Subject to Section 13.2 hereof, the Liens on the Collateral will be released, or subordinations of Liens on the Collateral will be
granted, with respect to the Notes and the Subsidiary Guarantees, as applicable: 
 (1) in whole, upon payment in
full of the principal of, accrued and unpaid interest, and premium, if any, on the Notes and payment in full of all other obligations under this Indenture, the Subsidiary Guarantees and the Security Documents that are due and payable at or prior to
the time of such principal together with accrued and unpaid interest; 
 (2) in whole upon: 

(a) satisfaction and discharge of this Indenture as set forth under Article VIII; or 

(b) a Legal Defeasance or Covenant Defeasance of this Indenture under Article VIII; 

(3) in part, as to any asset constituting Collateral (A) that is sold or otherwise disposed of by the Issuer or any
of the Subsidiary Guarantors in a transaction permitted by the First-Lien Documents (whether or not an “event of default” under the First-Lien Documents or any Second-Lien Notes Documents has occurred and is continuing) if all other Liens
on that asset securing the First-Lien Obligations (including all commitments thereunder) are released or (B) that is sold or otherwise disposed of by the Issuer or any Subsidiary Guarantor in accordance with, and as expressly provided for in,
this Indenture, the Intercreditor Agreement and the Security Documents; 
 (4) in whole, as to the ATP
Titan drilling and production platform and related assets, if such assets are contributed to an Infrastructure Subsidiary in connection with its designation as an Unrestricted Subsidiary in accordance with the definition thereof; 

(5) as set forth under Article IX as to property that constitutes less than all or substantially all of the Collateral,
with the consent of Holders of at least a majority in aggregate principal amount of the Notes then outstanding, voting as one class (or, in the case of a release of all or substantially all of the Collateral, with the consent of the Holders of at
least 75% in aggregate principal amount of the Notes then outstanding, voting as one class), including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes; and 

 -150- 

 

 (6) with respect to assets of a Subsidiary Guarantor upon release of such
Subsidiary Guarantor from its Subsidiary Guarantee as set forth under Article XII. 
 On the date of Discharge of First-Lien
Obligations, the Second-Priority Liens on the Collateral securing the Notes will not be released, except to the extent the Collateral or any portion thereof was disposed of in order to repay the First-Lien Obligations secured by the Collateral, and
thereafter the Collateral Agent (or another designated representative acting at the direction of the Holders of a majority of outstanding principal amount of the Notes) will have the right (upon the occurrence of an Event of Default) to foreclose
upon the Collateral (but in such event, the Liens on the Collateral securing the Notes will be released when such Event of Default and all other Events of Default under this Indenture cease to exist); provided, however, that if the
Issuer or any Subsidiary Guarantor subsequently incurs First-Lien Obligations that are secured by Liens on property or assets of the Issuer or any Subsidiary Guarantor of the type constituting the Collateral and the related Liens are incurred in
reliance on clause (1) of the definition of Permitted Liens, then the Issuer and the Subsidiary Guarantors will be required to reinstitute the security arrangements and Intercreditor Agreement with respect to the Collateral in favor of the
Notes, which, in the case of any such subsequent First-Lien Obligations, will be Second-Priority Liens on the Collateral securing such First-Lien Obligations to the same extent provided by the Security Documents and Intercreditor Agreement and on
the terms and conditions of the security documents relating to such First-Lien Obligations, with the Second-Priority Lien held either by the administrative agent, collateral agent or other representative for such First-Lien Obligations or by a
collateral agent or other representative designated by the Issuer to hold the Second-Priority Liens for the benefit of the holders of the Notes and subject to an intercreditor agreement that provides the administrative agent or collateral agent
substantially the same rights and powers as afforded under the Intercreditor Agreement. 
 In accordance with the Intercreditor
Agreement and upon compliance by the Issuer or any Subsidiary Guarantor, as the case may be, with the conditions precedent required by this Indenture, the Trustee or the Collateral Agent shall promptly cause to be released and reconveyed to the
Issuer, or the Subsidiary Guarantor, as the case may be, the released Collateral. Prior to each proposed release, the Issuer and each Subsidiary Guarantor shall furnish to the Trustee and the Collateral Agent all certificates, opinions and documents
required by this Indenture, the Security Documents and the TIA. 
 SECTION 13.4. Maintenance of Collateral.

 The Issuer shall, and shall cause each of the Subsidiary Guarantors to: 

(1) maintain, develop and operate the interests being mortgaged in a good and workmanlike manner and observe and comply
with all of the terms and provisions, of all oil and gas leases relating to the mortgaged interests so long as such oil 

 -151- 

 

 
and gas leases are capable of producing Hydrocarbons in paying quantities, except where such failure to comply would not have a material adverse effect; 

(2) comply with all contracts and agreements applicable to or relating to the Mortgaged Property or the production and
sale of Hydrocarbons therefrom, except to the extent a failure to so comply would not have a material adverse effect; 

(3) maintain, preserve and keep all operating equipment used with respect to the Mortgaged Property in proper repair,
working order and condition, and make all necessary or appropriate repairs, renewals, replacements, additions and improvements thereto so that the efficiency of such operating equipment shall at all times be properly preserved and maintained, except
where such failure to comply would not have a material adverse effect; 
 (4) cause the Mortgaged Property to be
kept free and clear of all Liens other than Permitted Liens; 
 (5) keep adequately insured by insurers of
recognized responsibility, all of the Mortgaged Property of an insurable nature and of a character usually insured by Persons engaged in the same or similar business, against all risks customarily insured against by such Persons; and 

(6) not sell, lease, transfer, abandon or otherwise dispose of any portion of the Mortgaged Property or any of
Mortgagor’s rights, titles or interests therein or thereto, except as specifically permitted by this Indenture. 
 SECTION
13.5. Information Regarding Collateral. 
 (a) The Issuer shall promptly notify the Collateral Agent if any
material portion of the Collateral is physically damaged, destroyed or condemned. 
 (b) Each year, within 120 days after the
end of the preceding fiscal year, the Issuer shall deliver to the Trustee and the Collateral Agent a certificate of a responsible financial or accounting Officer setting forth the information required pursuant to the schedules required by the
Security Documents or confirming that there has been no change in such information since the date of the prior annual financial statements. 

(c) Any certificate or opinion required by Section 314(d) of the TIA may be made by an Officer of the Issuer, except in cases where
Section 314(d) requires that such certificate or opinion be made by an independent engineer, appraiser or other expert. 

(d) Notwithstanding anything to the contrary herein, the Issuer and its Subsidiaries will not be required to comply with all or any
portion of Section 314(d) of the TIA if 

 -152- 

 

 
they determine, in good faith based on advice of counsel, that under the terms of that section and/or any interpretation or guidance as to the meaning thereof of the SEC and its staff, including
“no action” letters or exemptive orders, all or any portion of Section 314(d) of the TIA is inapplicable to the released Collateral. 

(e) Without limiting the generality of Section 13.5(c) above, certain no action letters issued by the SEC have permitted an
indenture qualified under the TIA to contain provisions permitting the release of Collateral from Liens under such indenture in the ordinary course of the Issuer’s business without requiring the Issuer to provide certificates and other
documents under Section 314(d) of the TIA. The Issuer and the Subsidiary Guarantors may, subject to the provisions of this Indenture without any release or consent by the Trustee, the Collateral Agent or First-Lien Collateral Agent, conduct
ordinary course activities with respect to the Collateral, including, without limitation: 
 (1) selling or
otherwise disposing of, in any transaction or series of related transactions, any property subject to the Lien of the Security Documents that has become worn out, defective, obsolete or not used or useful in the business; 

(2) abandoning, terminating, canceling, releasing or making alterations in or substitutions of any leases or contracts
subject to the Lien of the Indenture or any of the Security Documents; 
 (3) surrendering or modifying any
franchise, license or permit subject to the Lien of the Security Documents that it may own or under which it may be operating; 

(4) altering, repairing, replacing, changing the location or position of and adding to its structures, machinery, systems,
equipment, fixtures and appurtenances; 
 (5) selling, transferring or otherwise disposing of inventory or
accounts receivable in the ordinary course of business; and 
 (6) making cash payments (including for the
repayment of Indebtedness or interest) from cash that is at any time part of the Collateral in the ordinary course of business that are not otherwise prohibited by this Indenture and the Security Documents. 

SECTION 13.6. Suits to Protect the Collateral. 

Subject to the provisions of Article VI hereof and the Security Documents, the Trustee in its sole discretion and without the consent of
the Holders, on behalf of the Holders, may, and upon direction of a majority of Holders shall, direct the Collateral Agent to take all actions it deems necessary or appropriate in order to: 

 -153- 

 

 (a) enforce any of the terms of the Security Documents; and 

(b) collect and receive any and all amounts payable in respect of the obligations hereunder. 

Subject to the provisions of the Security Documents, the Trustee shall have power to institute and to maintain such suits and proceedings
as it may deem expedient to prevent any impairment of the Collateral by any acts which may be unlawful or in violation of any of the Security Documents or this Indenture, and such suits and proceedings as the Trustee, in its sole discretion, may
deem expedient to preserve or protect its interests and the interests of the Holders in the Collateral (including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other
governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the Lien on the Collateral or be prejudicial to the interests of the
Holders or the Trustee). Nothing in this Section 13.6 shall be considered to impose any such duty or obligation to act on the part of the Trustee. 

SECTION 13.7. Authorization of Receipt of Funds by the Trustee Under the Security Documents. 

Subject to the provisions of an Intercreditor Agreement, the Trustee is authorized to receive any funds for the benefit of the Holders
distributed under the Security Documents, and to make further distributions of such funds to the Holders according to the provisions of this Indenture. 

SECTION 13.8. Purchase Protected. 

In no event shall any purchaser in good faith of any property purported to be released hereunder be bound to ascertain the authority of
the Collateral Agent or the Trustee to execute the release or to inquire as to the satisfaction of any conditions required by the provisions hereof for the exercise of such authority or to see to the application of any consideration given by such
purchaser or other transferee; nor shall any purchaser or other transferee of any property or rights permitted by this Article XIII to be sold be under any obligation to ascertain or inquire into the authority of the Issuer or the applicable
Subsidiary Guarantor to make any such sale or other transfer. 
 SECTION 13.9. Powers Exercisable by Receiver or
Trustee. 
 In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the
powers conferred in this Article XIII upon the Issuer or a Subsidiary Guarantor with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument signed by such receiver or
trustee shall be 

 -154- 

 

 
deemed the equivalent of any similar instrument of the Issuer or a Subsidiary Guarantor or of any officer or officers thereof required by the provisions of this Article XIII; and if the Trustee
shall be in the possession of the Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee. 

SECTION 13.10. Release upon Termination of the Issuer’s Obligations. 

In the event that the Issuer delivers to the Trustee, in form and substance reasonably acceptable to it, an Officer’s Certificate
certifying that (i) payment in full of the principal of, together with accrued and unpaid interest (including additional interest, if any) on, the Notes and all other Obligations under this Indenture, the Subsidiary Guarantees and the Security
Documents that are due and payable at or prior to the time such principal, together with accrued and unpaid interest, are paid or (ii) the Issuer shall have exercised its Legal Defeasance option or its Covenant Defeasance option, in each case
in compliance with the provisions of Article VIII, the Trustee shall deliver to the Issuer and the Collateral Agent a notice stating that the Trustee, on behalf of the Holders, disclaims and gives up any and all rights it has in or to the Collateral
(other than with respect to funds held by the Trustee pursuant to Article XIII), and any rights it has under the Security Documents, and upon receipt by the Collateral Agent of such notice, the Collateral Agent shall be deemed not to hold a Lien in
the Collateral on behalf of the Trustee and shall do or cause to be done all acts reasonably necessary to release such Lien as soon as is reasonably practicable. 

SECTION 13.11. Collateral Agent. 

(a) The Trustee and each of the Holders by acceptance of the Notes hereby designates and appoints the Collateral Agent as its agent under
this Indenture and the Security Documents and the Trustee and each of the Holders by acceptance of the Notes hereby irrevocably authorizes the Collateral Agent to take such action on its behalf under the provisions of this Indenture and the Security
Documents and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Indenture and the Security Documents, together with such powers as are reasonably incidental thereto. The
Collateral Agent agrees to act as such on the express conditions contained in this Section 13.11. The provisions of this Section 13.11 are solely for the benefit of the Collateral Agent and none of the Trustee, any of the Holders nor the
Issuer or any of the Subsidiary Guarantors shall have any rights as a third party beneficiary of any of the provisions contained herein other than as expressly provided in Section 13.3. Notwithstanding any provision to the contrary contained
elsewhere in this Indenture and the Security Documents, the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor shall the Collateral Agent have or be deemed to have any fiduciary relationship
with the Trustee, any Holder or the Issuer or any Subsidiary Guarantor, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture and the Security Documents or otherwise exist against
the Collateral Agent. Without limiting the generality of 

 -155- 

 

 
the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express)
obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties. Except
as expressly otherwise provided in this Indenture, the Collateral Agent shall have and may use its sole discretion with respect to exercising or refraining from exercising any discretionary rights or taking or refraining from taking any actions
which the Collateral Agent is expressly entitled to take or assert under this Indenture and the Security Documents, including the exercise of remedies pursuant to Article VI, and any action so taken or not taken shall be deemed consented to by the
Trustee and the Holders. 
 (b) The Collateral Agent may execute any of its duties under this Indenture or the Security
Documents by or through agents, employees or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Collateral Agent shall not be responsible for the negligence or misconduct of any agent,
employee or attorney-in-fact that it selects as long as such selection was made with due care. 
 (c) None of the Collateral
Agent or any of its agents or employees shall (i) be liable for any action taken or omitted to be taken by any of them under or in connection with this Indenture or the transactions contemplated hereby (except for its own gross negligence or
willful misconduct) or under or in connection with the any Security Document or the transactions contemplated thereby (except for its own gross negligence or willful misconduct), or (ii) be responsible in any manner to the Trustee or any Holder
or any other Person for any recital, statement, representation, warranty, covenant or agreement made by the Issuer or any Subsidiary Guarantor, contained in this or any Indenture, or in any certificate, report, statement or other document referred
to or provided for in, or received by the Collateral Agent under or in connection with, this or any other Indenture or the Security Documents, or the validity, effectiveness, genuineness, enforceability or sufficiency of this or any other Indenture
or the Security Documents, or for any failure of the Issuer or any Subsidiary Guarantor or any other party to this Indenture or the Security Documents to perform its obligations hereunder or thereunder. None of the Collateral Agent or any of its
agents or employees shall be under any obligation to the Trustee or any Holder or any other Person to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this or any other Indenture or
the Security Documents or to inspect the properties, books or records of the Issuer or any Subsidiary Guarantor. 
 (d) The
Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone message, statement or other document or
conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel (including, without limita-

 -156- 

 

 
tion, counsel to the Issuer or any Subsidiary Guarantor), independent accountants and other experts and advisors selected by the Collateral Agent. The Collateral Agent shall be fully justified in
failing or refusing to take any action under this Indenture or any other indenture or the Security Documents unless it shall first receive such advice or concurrence of the Trustee as it deems appropriate and, if it so requests, it shall first be
indemnified to its satisfaction by the Holders or the applicable authorized representative against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Collateral Agent shall in
all cases be fully protected in acting, or in refraining from acting, under this Indenture or any other indenture or the Security Documents in accordance with a request or consent of the Trustee or the applicable authorized representative and such
request and any action taken or failure to act pursuant thereto shall be binding upon all of the Holders or any other Person. 

(e) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, unless the
Collateral Agent shall have received written notice from the Trustee or the Issuer referring to this Indenture, describing such Default or Event of Default and stating that such notice is a “notice of default.” The Collateral Agent shall
take such action with respect to such Default or Event of Default as may be requested by the Trustee in accordance with Article VI (subject to this Section 13.11); provided, however, that unless and until the Collateral Agent has
received any such request, the Collateral Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable. 

(f) The Bank of New York Mellon Trust Company, N.A. and its Affiliates (and any successor Collateral Agent and its Affiliates) may make
loans to, issue letters of credit for the account of, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting, or other business with the Issuer and the Subsidiary
Guarantors as though it was not the Collateral Agent hereunder and without notice to or consent of the Trustee. The Trustee and the Holders acknowledge that, pursuant to such activities, the Bank of New York Mellon Trust Company, N.A. or its
Affiliates (and any successor Collateral Agent and its Affiliates) may receive information regarding the Issuer and the Subsidiary Guarantors (including information that may be subject to confidentiality obligations in favor of the Issuer and the
Subsidiary Guarantors) and acknowledge that the Collateral Agent shall not be under any obligation to provide such information to the Trustee or the Holders. Nothing herein shall impose or imply any obligation on the part of the Bank of New York
Mellon Trust Company, N.A. (or any successor Collateral Agent) to advance funds. 
 (g) The Collateral Agent may resign at any
time upon thirty (30) days prior written notice to the Trustee and the Issuer, such resignation to be effective upon the acceptance of a successor agent to its appointment as Collateral Agent. If the Collateral Agent resigns under this
Indenture, the Trustee, subject to the consent of the Issuer (which shall not be 

 -157- 

 

 
unreasonably withheld and which shall not be required during a continuing Event of Default), shall appoint a successor Collateral Agent. If no successor collateral agent is appointed prior to the
intended effective date of the resignation of the Collateral Agent (as stated in the notice of resignation), the Collateral Agent may appoint, after consulting with the Trustee, subject to the consent of the Issuer (which shall not be unreasonably
withheld and which shall not be required during a continuing Event of Default), a successor collateral agent. If no successor collateral agent is appointed and consented to by the Issuer pursuant to the preceding sentence within thirty
(30) days after the intended effective date of resignation (as stated in the notice of resignation) the Collateral Agent shall be entitled to petition at the expense of the Issuer a court of competent jurisdiction to appoint a successor. Upon
the acceptance of its appointment as successor collateral agent hereunder, such successor collateral agent shall succeed to all the rights, powers and duties of the retiring Collateral Agent, and the term “Collateral Agent” shall mean such
successor collateral agent, and the retiring Collateral Agent’s appointment, powers and duties as the Collateral Agent shall be terminated. After the retiring Collateral Agent’s resignation hereunder, the provisions of this
Section 13.11 (and Section 13.12) shall continue to inure to its benefit and the retiring Collateral Agent shall not by reason of such resignation be deemed to be released from liability as to any actions taken or omitted to be taken by it
while it was the Collateral Agent under this Indenture. 
 (h) The Trustee shall initially act as Collateral Agent and shall be
authorized to appoint co-Collateral Agents as necessary in its sole discretion. Except as otherwise explicitly provided herein or in the Security Documents, neither the Collateral Agent nor any of its officers, directors, employees or agents shall
be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any other Person or to take any other
action whatsoever with regard to the Collateral or any part thereof. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither the Collateral Agent nor any of its
officers, directors, employees or agents shall be responsible for any act or failure to act hereunder, except for its own willful misconduct, gross negligence or bad faith. 

(i) The Trustee, as such and as Collateral Agent, is authorized and directed to (A) enter into the Security Documents,
(B) enter into the Intercreditor Agreement, (C) bind the Holders on the terms as set forth in the Security Documents and the Intercreditor Agreement and (D) perform and observe its obligations under the Security Documents and the
Intercreditor Agreement. 
 (j) The Trustee agrees that it shall not (and shall not be obliged to), and shall not instruct the
Collateral Agent to, unless specifically requested to do so by a majority of the Holders, take or cause to be taken any action to enforce its rights under this Indenture or against the Issuer and the Subsidiary Guarantors, including the commencement
of any legal 

 -158- 

 

 
or equitable proceedings, to foreclose any Lien on, or otherwise enforce any security interest in, any of the Collateral. 

(k) If at any time or times the Trustee shall receive (i) by payment, foreclosure, set-off or otherwise, any proceeds of Collateral
or any payments with respect to the Obligations arising under, or relating to, this Indenture, except for any such proceeds or payments received by the Trustee from the Collateral Agent pursuant to the terms of this Indenture, or (ii) payments
from the Collateral Agent in excess of the amount required to be paid to the Trustee pursuant to Article VI, the Trustee shall promptly turn the same over to the Collateral Agent, in kind, and with such endorsements as may be required to negotiate
the same to the Collateral Agent. 
 (l) Should the Trustee obtain possession of any such Collateral, upon request from the
Issuer, the Trustee shall notify the Collateral Agent thereof, and, promptly upon the Collateral Agent’s request therefor, shall deliver such Collateral to the Collateral Agent or otherwise deal with such Collateral in accordance with the
Collateral Agent’s instructions. 
 (m) The Collateral Agent shall have no obligation whatsoever to the Trustee or any of
the Holders or any other Person to assure that the Collateral exists or is owned by the Issuer and the Subsidiary Guarantors or is cared for, protected or insured or has been encumbered, or that the Collateral Agent’s Liens have been properly
or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all of the Grantor’s property constituting collateral intended to be subject to the Lien and
security interest of the Security Documents has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof or title thereto, or to exercise at all or in any particular
manner or under any duty of care, disclosure or fidelity, or to continue exercising, any of the rights, authorities and powers granted or available to the Collateral Agent pursuant to this Indenture or any Security Document, it being understood and
agreed that in respect of the Collateral, or any act, omission or event related thereto, the Collateral Agent may act in any manner it may deem appropriate, in its sole discretion given the Collateral Agent’s own interest in the Collateral, and
that the Collateral Agent shall have no other duty or liability whatsoever to the Trustee or any Holder or any other Person as to any of the foregoing. 

(n) No provision of this Indenture or any Security Document shall require the Collateral Agent (or the Trustee) to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of its duties hereunder or thereunder or to take or omit to take any action hereunder or thereunder or take any action at the request or direction of Holders (or the Trustee
in the case of the Collateral Agent). 
 (o) The Collateral Agent (i) shall not be liable for any action it takes or omits
to take in good faith which it reasonably believes to be authorized or within its rights or 

 -159- 

 

 
powers, or for any error of judgment made in good faith by a Trust Officer, unless it is proved that the Collateral Agent was grossly negligent in ascertaining the pertinent facts,
(ii) shall not be liable for interest on any money received by it except as the Collateral Agent may agree in writing with the Issuer (and money held in trust by the Collateral Agent need not be segregated from other funds except to the extent
required by law), and (iii) may consult with counsel of its selection and the advice or opinion of such counsel as to matters of law shall be full and complete authorization and protection from liability in respect of any action taken, omitted
or suffered by it in good faith and in accordance with the advice or opinion of such counsel. The grant of permissive rights or powers to the Collateral Agent shall not be construed to impose duties to act. 

(p) Notwithstanding anything to the contrary herein, the obligations of the Issuer and Subsidiary Guarantors owing to the Collateral
Agent shall remain in full force and effect and all of the Collateral Agent’s rights, protections, indemnities and immunities granted hereunder shall survive the satisfaction and discharge of the Indenture so long as any Mortgage to which the
Collateral Agent is a party remains effective and outstanding. 
 SECTION 13.12. Compensation and
Indemnification. 
 The Collateral Agent shall be entitled to the compensation, reimbursement of expenses,
disbursements and advances, and indemnification set forth in Section 7.7 (with the references to the Trustee therein being deemed to refer to the Collateral Agent). 

SECTION 13.13. Security Documents; Intercreditor Agreement; Other Security Documents. 

(a) The Trustee and the Collateral Agent is each hereby directed and authorized to execute and deliver the Intercreditor Agreement,
Mortgages, the Pledge Agreements and the other Security Documents in which it is named as a party. It is hereby expressly acknowledged and agreed that, in doing so, the Trustee and the Collateral Agent are not responsible for the terms or contents
of such agreements, or for the validity or enforceability thereof, or the sufficiency thereof for any purpose. Whether or not so expressly stated therein, in entering into, or taking (or forbearing from) any action under or pursuant to, the
Intercreditor Agreement, the Mortgages, the Pledge Agreements or any other Security Documents, the Trustee and Collateral Agent each shall have all of the rights, immunities, indemnities and other protections granted to it under this Indenture (in
addition to those that may be granted to it under the terms of such other agreement or agreements). 
 (b) The security
interests securing the Notes and the Subsidiary Guarantees will be, pursuant to the Intercreditor Agreement, second in priority to any and all security interests ay any time granted to secure the First-Lien Obligations and will also be subject to
all other Permitted Liens. The Intercreditor defines the relative rights of holders of Second-Priority Liens and holders of First-Priority Liens.

11.875% Senior Second Lien Note due 2015 

(1) Interest. ATP OIL & GAS CORPORATION (the “Issuer”) promises to pay interest on the principal amount of this
Note at the rate per annum shown above, including any Liquidated Damages, if any, payable in the form of additional interest pursuant to Section 2(d) 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 April 23, 2010. The Issuer will pay interest semi-annually in arrears on each Interest Payment Date, commencing November 1, 2010. 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. 

(2) Method of Payment. The Issuer shall pay interest on the Notes 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 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 Melon 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 April 23, 2010 (the “Indenture”), among
the Issuer, the Trustee and the Collateral Agent. This Note is one of a duly authorized issue of Notes of the Issuer designated as its 11.875% Senior Second Lien Notes due 2015 (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 the TIA for a statement of them. The Notes are general secured obligations of the Issuer. Payment on each Note is guaranteed on a senior basis by
the Subsidiary Guarantors pursuant to Article 12 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.

 (5) Redemption. (a) Except as set forth in Sections 3.3(b) and (c) of the
Indenture, the Issuer will not be entitled to redeem the Notes at its option prior to May 1, 2013. 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 May 1, 2013, at
the following Redemption Prices (expressed as percentages of the principal amount thereof) if redeemed during the twelve-month period commencing on May 1 of the years set forth below, plus, in each case, accrued and unpaid interest thereon to
the date of redemption: 
  

				
	 Year
	  	Percentage	 
	 2013
	  	111.875	% 
	 2014
	  	100.000	% 

 (b) At any
time, or from time to time, prior to May 1, 2013, the Issuer may, at its option, use all or a portion of the Net Cash Proceeds of one or more Equity Offerings to redeem up to 35% of the aggregate principal amount of the Notes (including any
Additional Notes) issued under the Indenture at a Redemption Price equal to 111.875% of the aggregate principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon to the date of redemption; provided that: (1) at
least 65% of the aggregate principal amount of Notes issued under the Indenture on the Issue Date remains outstanding immediately after giving effect to any such redemption; and (2) the Issuer makes such redemption not more than 90 days
after the consummation of any such Equity Offering. 
 (c) In addition, the Notes may be redeemed, in whole or in part, at any
time prior to May 1, 2013 at the option of the Issuer at a Redemption Price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest 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). 

(6) Notice of Redemption. Notice of redemption will be mailed at least 30 days but not more than 60 days before the Redemption
Date to each Holder of Notes to be redeemed at such Holder’s registered address. Notes in denominations larger than $2,000 may be redeemed in part. 

Except as set forth in the Indenture, if monies for the redemption of the Notes called for redemption shall have been deposited with the
Paying Agent for redemption on such Redemption Date, then, unless the Issuer defaults in the payment of such Redemption Price plus accrued interest the Notes called for redemption will cease to bear interest from and after such Redemption Date and
the only right of the Holders of such Notes will be to receive payment of the Redemption Price plus accrued interest. 
 (7)
Offers to Purchase. Sections 4.15 and 4.16 of the Indenture provide that, upon the occurrence of a Change of Control (as defined in the Indenture) and after certain Asset Dispositions (as defined in the Indenture), and subject to further
limitations con- 
  

 A-4 

 
tained therein, the Issuer will make an offer to purchase certain amounts of the Notes in accordance with the procedures set forth in the Indenture. 

(8) Denominations; Transfer; Exchange. The Notes are in registered form, without coupons, and in denominations of at least $2,000
and integral multiples of $1,000 thereafter. A Holder shall register the transfer of or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer
documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Notes or portions thereof selected for
redemption. 
 (9) Persons Deemed Owners. The registered Holder of a Note shall be treated as the owner of it for all
purposes. 
 (10) Unclaimed Money. If money for the payment of principal or interest remains unclaimed for one year, the
Trustee and the Paying Agent will pay the money back to the Issuer. After that, all liability of the Trustee and such Paying Agent with respect to such money shall cease. 

(11) Discharge Prior to Redemption or Maturity. If the Issuer at any time deposits with the Trustee U.S. Legal Tender or U.S.
Government Obligations sufficient to pay the principal of and interest on the Notes to redemption or maturity and comply with the other provisions of the Indenture relating thereto, the Issuer will be discharged from certain provisions of the
Indenture and the Notes (including certain covenants, but including, under certain circumstances, its obligation to pay the principal of and interest on the Notes but without affecting the rights of the Holders to receive such amounts from such
deposits). 
 (12) Amendment; Supplement; Waiver. Subject to certain exceptions set forth in the Indenture, the Indenture
or the Notes or the Subsidiary Guarantees may be amended or supplemented with the written consent of the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding, and any past Default or Event of Default or
noncompliance with any provision may be waived with the written consent of the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding. Without notice to or consent of any Holder, the parties thereto may amend
or supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Notes in addition to or in place of certificated Notes, comply with any requirements of the SEC in order to
effect or maintain the qualification of the Indenture under the TIA or comply with Article V of the Indenture or make any other change that does not adversely affect the rights of any Holder of a Note. 

(13) Restrictive Covenants. The Indenture imposes certain limitations on the ability of the Issuer and its Restricted Subsidiaries
to, among other things, incur additional Indebtedness, make payments in respect of their Capital Stock or certain Indebtedness, make 

 

 A-5 

 
certain Investments, create or incur liens, enter into transactions with Affiliates, create dividend or other payment restrictions affecting Restricted Subsidiaries, issue Preferred Stock of
their Restricted Subsidiaries, and on the ability of the Issuer and its Restricted Subsidiaries to merge or consolidate with any other Person or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of the
Issuer’s and its Restricted Subsidiaries’ assets or adopt a plan of liquidation. Such limitations are subject to a number of important qualifications and exceptions. Pursuant to Section 4.6 of the Indenture, the Issuer must annually
report to the Trustee on compliance with such limitations. 
 (14) Successors. When a successor assumes, in accordance
with the Indenture, all the obligations of its predecessor under the Notes and the Indenture, the predecessor, subject to certain exceptions, will be released from those obligations. 

(15) Defaults and Remedies. Except as set forth in the Indenture, if an Event of Default occurs and is continuing, the Trustee or
the Holders of not less than 25% in principal amount of Notes then outstanding may declare all the Notes to be due and payable in the manner, at the time and with the effect provided in the Indenture. Holders of Notes may not enforce the Indenture
or the Notes except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes unless it has received indemnity or security satisfactory to it. The Indenture permits, subject to certain limitations therein

The Credits 

Section 2.01 Commitments. Subject to the terms and conditions set forth herein, each Lender agrees to make Loans to the
Borrower during the Availability Period in an aggregate principal amount that will not result in (a) such Lender’s Revolving Credit Exposure exceeding such Lender’s Commitment or (b) the total Revolving Credit Exposures exceeding
the total Commitments. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, repay and reborrow the Loans. 

Section 2.02 Loans and Borrowings. 

(a) Borrowings; Several Obligations. Each Loan shall be made as part of a Borrowing consisting of Loans made by the
Lenders ratably in accordance with their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments are several and no
Lender shall be responsible for any other Lender’s failure to make Loans as required. 
  

 35 

 (b) Types of Loans. Subject to Section 3.03, each Borrowing
shall be comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may request in accordance herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make
such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement. 

(c) Minimum Amounts; Limitation on Number of Borrowings. At the commencement of each Interest Period for any
Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $500,000 and not less than $3,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an
integral multiple of $500,000 and not less than $1,000,000; provided that an ABR Borrowing may be in a lesser aggregate amount that is equal to the entire unused balance of the total Commitments or that is required to finance the reimbursement of an
LC Disbursement as contemplated by Section 2.08(e). Borrowings of more than one Type may be outstanding at the same time, provided that there shall not at any time be more than a total of eight Eurodollar Borrowings outstanding. Notwithstanding
any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date. 

(d) Notes. If requested by a Lender, the Loans made by each Lender shall be evidenced by a single promissory note
of the Borrower in substantially the form of Exhibit A, dated, in the case of (i) any Lender party hereto as of the date of this Agreement, as of the date of this Agreement, (ii) any Lender that becomes a party hereto pursuant to an
Assignment and Assumption, as of the effective date of the Assignment and Assumption, or (iii) any Lender that becomes a party hereto in connection with an increase in the Aggregate Maximum Credit Amounts pursuant to Section 2.06(c), as of
the effective date of such increase, payable to the order of such Lender in a face principal amount of up to its Maximum Credit Amount as in effect on such date, and otherwise duly completed. In the event that any Lender’s Maximum Credit Amount
increases or decreases for any reason (whether pursuant to Section 2.06, Section 12.04(b) or otherwise), the Borrower shall deliver or cause to be delivered on the effective date of such increase or decrease, a new Note payable to such
Lender in a principal amount equal to its Maximum Credit Amount after giving effect to such increase or decrease, and otherwise duly completed. The date, amount, Type, interest rate and, if applicable, Interest Period of each Loan made by each
Lender, and all payments made on account of the principal thereof, shall be recorded by such Lender on its books for its Note, and, prior to any transfer, may be endorsed by such Lender on a schedule attached to such Note or any continuation thereof
or on any separate record maintained by such Lender. Failure to make any such notation or to attach a schedule shall not affect any Lender’s or the Borrower’s rights or obligations in respect of such Loans or affect the validity of such
transfer by any Lender of its Note. 
 Section 2.03 Requests for Borrowings. To request a Borrowing, the Borrower
shall notify the Administrative Agent of such request by telephone or e-mail, with respect to the initial Borrowing on the date of closing, and by telephone or e-mail, with respect to each subsequent Borrowing, (a) in the case of a Eurodollar
Borrowing, not later than 12:00 Noon, New York City time, three Business Days before the date of the proposed Borrowing or (b) in the case of an ABR Borrowing, not later than 11:00 a.m., New York City time, on the date of the proposed

  

 36 

 
Borrowing; provided that no such notice shall be required for any deemed request of an ABR Borrowing to finance the reimbursement of an LC Disbursement as provided in Section 2.08(e). Each
such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request in substantially the form of Exhibit B and signed by the Borrower.
Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02:

Borrowing Base, the current total Revolving Credit Exposures (without regard to the requested Borrowing) and the pro forma total Revolving Credit Exposures (giving effect to the requested Borrowing); and 

(f) the location and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the
requirements of Section 2.05. 
 If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR
Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Each Borrowing Request shall constitute a
representation that the amount of the requested Borrowing shall not cause the total Revolving Credit Exposures to exceed the total Commitments (i.e., the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base).

 Promptly following receipt of a Borrowing Request in accordance with this Section 2.03, the Administrative Agent shall advise each
Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing. 

Section 2.04 Interest Elections. 

(a) Conversion and Continuance. Each Borrowing initially shall be of the Type specified in the applicable Borrowing
Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in
the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section 2.04. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such
portion shall be allocated ratably 
  

 37 

 
among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. 

(b) Interest Election Requests. To make an election pursuant to this Section 2.04, the Borrower shall notify
the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective
date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in substantially the form of
Exhibit C and signed by the Borrower. 
 (c) Information in Interest Election Requests. Each telephonic
and written Interest Election Request shall specify the following information in compliance with Section 2.02: 

(i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect
to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to Section 2.04(c)(ii) and (iii) shall be specified for each resulting Borrowing);

 (ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a
Business Day; 
 (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

 (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after
giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”. 
 If any such
Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. 

(d) Notice to Lenders by the Administrative Agent. Promptly following receipt of an Interest Election Request, the
Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing. 

(e) Effect of Failure to Deliver Timely Interest Election Request and Events of Default and Borrowing Base Deficiencies
on Interest Election. If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided
herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default or a Borrowing Base Deficiency has occurred and is continuing: (i) no
outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing (and any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing

  

 38 

 
shall be ineffective) and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto. 

Section 2.05 Funding of Borrowings. 

(a) Funding by Lenders. Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by
wire transfer of immediately available funds by 2:00 p.m., New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans
available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Administrative Agent in New York, New York or such other account designated by Borrower in the applicable
Borrowing Request; provided that ABR Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.08(e) shall be remitted by the Administrative Agent to the Issuing Bank. Nothing herein shall be deemed to obligate any
Lender to obtain the funds for its Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for its Loan in any particular place or manner. 

(b) Presumption of Funding by the Lenders. Unless the Administrative Agent shall have received notice from a Lender
prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such
date in accordance with Section 2.05(a) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the
Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount together with the accrued interest thereon without duplication, for each day from and
including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the
Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such
amount shall constitute such Lender’s Loan included in such Borrowing.

Increase of Aggregate Maximum Credit Amounts. 
 (a) Scheduled Termination of Commitments. Unless
previously terminated, the Commitments shall terminate on the Maturity Date. If at any time the Aggregate Maximum Credit Amounts are, or the Borrowing Base is, terminated or reduced to zero, then the Commitments shall terminate on the effective date

 (b) Optional Termination and Reduction of Aggregate Credit Amounts.

 (i) The Borrower may at any time terminate, or from time to time reduce, the Aggregate Maximum Credit Amounts;

after giving effect to any concurrent prepayment of the Loans in accordance with Section 3.04(b), the total Revolving Credit Exposures would exceed the total Commitments. 

(ii) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Aggregate Maximum
Credit Amounts under Section 2.06(b)(i) at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the
Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section 2.06(b)(ii) shall be irrevocable. Any termination or reduction of the Aggregate Maximum Credit Amounts shall
be permanent and may not be reinstated. Each reduction of the Aggregate Maximum Credit Amounts shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage.

(i) Subject to the conditions set forth in Section 2.06(c)(ii), the Borrower may increase the Aggregate Maximum

 (ii) Any increase in the Aggregate Maximum Credit Amounts shall be subject to the following additional
conditions: 
 (A) such increase shall not be less than $25,000,000 unless the Administrative Agent otherwise
consents, and no such increase shall be permitted if after giving effect thereto the Aggregate Maximum Credit Amounts would exceed $150,000,000.00; 

(B) no Event of Default shall have occurred and be continuing at the effective date of such increase; 

(C) on the effective date of such increase, no Eurodollar Borrowings shall be outstanding or if any Eurodollar Borrowings
are outstanding, then the effective date of such increase shall be the last day of the Interest Period in respect of such Eurodollar Borrowings unless the Borrower pays compensation required by Section 5.02; 

(D) no Lender’s Maximum Credit Amount may be increased without the consent of such Lender; 

(E) if the Borrower elects to increase the Aggregate Maximum Credit Amounts by increasing the Maximum Credit Amount of a
Lender, the Borrower and such Lender shall execute and deliver to the Administrative Agent a certificate substantially in the form of Exhibit G-1 (a “Maximum Credit Amount Increase Certificate”), together with a processing and
recordation fee of $3,500, and, if requested, the Borrower shall deliver a new Note payable to the order of such Lender in a principal amount equal to its Maximum Credit Amount after giving effect to such increase, and otherwise duly completed;

  

 40 

 (F) if the Borrower elects to increase the Aggregate Maximum Credit Amounts

Lender Certificate”), together with an Administrative Questionnaire and a processing and recordation fee of $3,500, and, if requested, the Borrower shall deliver a Note payable to the order of such Additional Lender in a principal amount
equal to its Maximum Credit Amount, and otherwise duly completed; and 
 (G) Each Additional Lender must be
approved in writing by the Administrative Agent. 
 (iii) Subject to acceptance and recording thereof pursuant to
Section 2.06(c)(iv), from and after the effective date specified in the Maximum Credit Amount Increase Certificate or the Additional Lender Certificate (or if any Eurodollar Borrowings are outstanding, then the last day of the Interest Period

Additional Lender Certificate, any Additional Lender party thereto shall be a party to this Agreement and the other Loan Documents and have the rights and obligations of a Lender under this Agreement and the other Loan Documents. In addition, the
Lender or the Additional Lender, as applicable, shall purchase a pro rata portion of the outstanding Loans (and participation interests in Letters of Credit) of each of the other Lenders (and such Lenders hereby agree to sell and to take all such
further action to effectuate such sale) such that each Lender (including any Additional Lender, if applicable) shall hold its Applicable Percentage of the outstanding Loans (and participation interests) after giving effect to the increase in the
Aggregate Maximum Credit Amounts.

the Administrative Agent, the Issuing Bank and the Lenders on April 1st and October 1st of each year, commencing October 1, 2010. In addition, the Borrower may, by notifying the Administrative Agent thereof, and the Administrative
Agent may, at the direction of the Required Lenders, by notifying the Borrower thereof, one time during any 12-month period, each elect to cause the Borrowing Base to be redetermined between Scheduled Redeterminations (an “Interim
Redetermination”) in accordance with this Section 2.07. 
 (c) Scheduled and Interim
Redetermination Procedure. 
 (i) Each Scheduled Redetermination and each Interim Redetermination shall be
effectuated as follows: Upon receipt by the Administrative Agent of (A) the Reserve Report and the Reserve Report Certificate, and (B) such other reports, data and supplemental information, including, without limitation, the information
provided pursuant to Section 8.12(c), as may, from time to time, be reasonably requested by the Majority Lenders (the Reserve Report, such certificate and such other reports, data and supplemental information being the “Engineering
Reports”), the Administrative Agent shall evaluate the information contained in the Engineering Reports and shall, in its sole discretion, propose a new Borrowing Base (the “Proposed Borrowing Base”) based upon such
information and such other information as the Administrative Agent deems appropriate in its sole discretion and consistent with its normal oil and gas lending criteria as it exists at the particular time. In no event shall the Borrowing Base exceed
the Aggregate Maximum Credit Amounts. 
 Without limitation of the generality of the foregoing, the Administrative Agent and the
Lenders will calculate the Borrowing Base considering the following factors: 
 (a) the Proved Reserves
attributable to the Borrower’s and its Subsidiaries’ Oil and Gas Properties; and 
 (b) the
Borrower’s direct or indirect interests in reusable floating infrastructure assets to the extent a Lien in form and substance reasonably satisfactory to the Administrative Agent can be granted on either the asset or the Borrower’s Capital
Stock in the Person owning the asset. 
 (ii) The Administrative Agent shall notify the Borrower and the Lenders
of the Proposed Borrowing Base (the “Proposed Borrowing Base Notice”): 
 (A) in the case of a
Scheduled Redetermination (1) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on or before the
March 15th and September 15th of such year following the date of delivery or (2) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and
(c) in a timely and complete manner, then promptly after the Administrative Agent has received complete Engineering Reports from 

 

 42 

 
the Borrower and has had a reasonable opportunity to determine the Proposed Borrowing Base in accordance with Section 2.07(c)(i); and 

(B) in the case of an Interim Redetermination, promptly, and in any event, within fifteen (15) days after the
Administrative Agent has received the required Engineering Reports. 
 (iii) Any Proposed Borrowing Base that
would increase the Borrowing Base then in effect must be approved or deemed to have been approved by all of the Lenders in their sole discretion as provided in this Section 2.07(c)(iii); and any Proposed Borrowing Base that would decrease or
maintain the Borrowing Base then in effect must be approved or be deemed to have been approved by the Required Lenders in their sole discretion as provided in this Section 2.07(c)(iii). Upon receipt of the Proposed Borrowing Base Notice, each
Lender shall have fifteen (15) days to agree with the Proposed Borrowing Base or disagree with the Proposed Borrowing Base by proposing an alternate Borrowing Base. If at the end of such fifteen (15) days, any Lender has not communicated
its approval or disapproval in writing to the Administrative Agent, such silence shall be deemed to be an approval of the Proposed Borrowing Base. If, at the end of such 15-day period, all of the Lenders, in the case of a Proposed Borrowing Base
that would increase the Borrowing Base then in effect, or the Required Lenders, in the case of a Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect, have approved or deemed to have approved, as aforesaid, then
the Proposed Borrowing Base shall become the new Borrowing Base, effective on the date specified in Section 2.07(d). If, however, at the end of such 15-day period, all of the Lenders or the Required Lenders, as applicable, have not approved or
deemed to have approved, as aforesaid, then the Administrative Agent shall poll the Lenders to ascertain the highest Borrowing Base then acceptable to all of the Lenders or a number of Lenders sufficient to constitute the Required Lenders, as
applicable, and, so long as such amount does not increase the Borrowing Base then in effect, such amount shall become the new Borrowing Base, effective on the date specified in Section 2.07(d). 

(d) Effectiveness of a Redetermined Borrowing Base. After a redetermined Borrowing Base is approved or is deemed to
have been approved by all of the Lenders or the Required Lenders, as applicable, pursuant to Section 2.07(c)(iii), the Administrative Agent shall notify the Borrower and the Lenders of the amount of the redetermined Borrowing Base (the
“New Borrowing Base Notice”), and such amount shall become the new Borrowing Base, effective and applicable to the Borrower, the Administrative Agent, the Issuing Bank and the Lenders: 

(i) in the case of a Scheduled Redetermination, (A) if the Administrative Agent shall have received the Engineering
Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on the April 1st or October 1st, as applicable, following such notice, or (B) if the Administrative
Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on the Business Day next succeeding delivery of such New Borrowing
Base Notice; and 
  

 43 

 (ii) in the case of an Interim Redetermination, on the Business Day next
succeeding delivery of such notice. 
 Such amount shall then become the Borrowing Base until the next Scheduled Redetermination Date, the next
Interim Redetermination Date or the next adjustment to the Borrowing Base under Section 2.07(e), Section 8.13(c), Section 9.05 or Section 9.12, whichever occurs first. Notwithstanding the foregoing, no Scheduled Redetermination
or Interim Redetermination shall become effective until the New Borrowing Base Notice related thereto is received by the Borrower. 

(e) Reduction of Borrowing Base Upon Termination of Hedge Positions. If the Borrower or any Subsidiary shall
terminate or create any off-setting positions in respect of any hedge positions (whether evidenced by a floor, put or Swap Agreement) upon which the Lenders relied in determining the Borrowing Base, then the Borrowing Base shall be contemporaneously
reduced in an amount determined by the Required Lenders equal to the economic value of such hedge positions. 

Section 2.08 Letters of Credit. 

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of dollar
denominated Letters of Credit for its own account or for the account of any of its Restricted Subsidiaries, in a form reasonably acceptable to the Administrative Agent and the Issuing Bank, at any time and from time to time during the Availability
Period; provided that the Borrower may not request the issuance, amendment, renewal or extension of Letters of Credit hereunder if a Borrowing Base Deficiency exists at such time or would exist as a result thereof. In the event of any inconsistency
between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Issuing Bank relating to any
Letter of Credit, the terms and conditions of this Agreement shall control. 
 (b) Notice of Issuance,
Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic
communication, if arrangements for doing so have been approved by the Issuing Bank) to the Issuing Bank and the Administrative Agent (not less than five (5) Business Days in advance of the requested date of issuance, amendment, renewal or
extension) a notice: 
 (i) requesting the issuance of a Letter of Credit or identifying the Letter of Credit to
be amended, renewed or extended; 
 (ii) specifying the date of issuance, amendment, renewal or extension (which
shall be a Business Day); 
 (iii) specifying the date on which such Letter of Credit is to expire (which shall
comply with Section 2.08(c)); 
 (iv) specifying the amount of such Letter of Credit; 

 

 44 

 (v) specifying the name and address of the beneficiary thereof and such
other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit; and 
 (vi)
specifying the amount of the then effective Borrowing Base and whether a Borrowing Base Deficiency exists at such time, the current total Revolving Credit Exposures (without regard to the requested Letter of Credit or the requested amendment,
renewal or extension of an outstanding Letter of Credit) and the pro forma total Revolving Credit Exposures (giving effect to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit).

 Each notice shall constitute a representation that after giving effect to the requested issuance, amendment, renewal or extension, as
applicable, (i) the LC Exposure shall not exceed the LC Commitment and (ii) the total Revolving Credit Exposures shall not exceed the total Commitments (i.e. the lesser of the Aggregate Maximum Credit Amounts and the then effective
Borrowing Base). 
 If requested by the Issuing Bank, the Borrower also shall submit a letter of credit application on the Issuing Bank’s
standard form in connection with any request for a Letter of Credit. 
 (c) Expiration Date. Each Letter
of Credit shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or
extension) and (ii) the date that is five Business Days prior to the Maturity Date. 
 (d)
Participations. On the date of the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or the Lenders, the Issuing Bank hereby
grants to each Lender, and each Lender hereby acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In
consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement
made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided in Section 2.08(e), or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its
obligation to acquire participations pursuant to this Section 2.08(d) in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any
Letter of Credit or the occurrence and continuance of a Default, the existence of a Borrowing Base Deficiency or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or
reduction whatsoever. 
 (e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect
of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on the date that such LC Disbursement is made, if
the Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date, 

 

 45 

 
or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 12:00 noon, New York City time, on (i) the Business Day that the Borrower
receives such notice, if such notice is received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior
to such time on the day of receipt; provided that if such LC Disbursement is not less than $1,000,000, the Borrower shall, subject to the conditions to Borrowing set forth herein, be deemed to have requested, and the Borrower does hereby request
under such circumstances, that such payment be financed with an ABR Borrowing in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR
Borrowing. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable
Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.05 with respect to
Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders.
Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this Section 2.08(e), the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made
payments pursuant to this Section 2.08(e) to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this Section 2.08(e) to reimburse the Issuing Bank
for any LC Disbursement (other than the funding of ABR Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement. 

(f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in
Section 2.08(e) shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or
enforceability of any Letter of Credit, any Letter of Credit Agreement or this Agreement, or of any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in
any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of
Credit or any Letter of Credit Agreement, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.08(f), constitute a legal or equitable
discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties shall have any liability or responsibility by reason
of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission,
interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical
terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any direct

  

 46 

 
damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by
the Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or
willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised all requisite care in each such determination. In furtherance of the foregoing and
without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion,
either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in
strict compliance with the terms of such Letter of Credit. 
 (g) Disbursement Procedures. The Issuing
Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed
by telecopy) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse
the Issuing Bank and the Lenders with respect to any such LC Disbursement. 
 (h) Interim Interest. If the
Issuing Bank shall make any LC Disbursement, then, until the Borrower shall have reimbursed the Issuing Bank for such LC Disbursement (either with its own funds or a Borrowing under Section 2.08(e)), the unpaid amount thereof shall bear
interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans. Interest accrued pursuant to this
Section 2.08(h) shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.08(e) to reimburse the Issuing Bank shall be for the account of such Lender to
the extent of such payment. 
 (i) Cash Collateralization. If (i) any Event of Default shall occur
and be continuing and the Borrower receives notice from the Administrative Agent or the Majority Lenders demanding the deposit of cash collateral pursuant to this Section 2.08(i), or (ii) the Borrower is required to pay to the
Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then the Borrower shall deposit, in an account with the Administrative Agent, in the name of the Administrative Agent
and for the benefit of the Lenders, an amount in cash equal to, in the case of an Event of Default, the LC Exposure, and in the case of a payment required by Section 3.04(c), the amount of such excess as provided in Section 3.04(c), as of
such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any
kind, upon the occurrence of any Event of Default with respect to the Borrower or any Restricted Subsidiary described in Section 10.01(h), Section 10.01(i) or Section 10.01(j). The Borrower hereby grants to the Administrative Agent,
for the benefit of the Issuing Bank and the Lenders, an exclusive first priority and continuing perfected security 
  

 47 

 
interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all deposits or wire transfers made
thereto, any and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise payable in respect of, or in
exchange for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. The Borrower’s obligation to deposit amounts pursuant to this
Section 2.08(i) shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest
extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower or any of its Subsidiaries may now or hereafter have against any such beneficiary, the
Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such deposit shall be held as collateral securing the payment and performance of the Borrower’s and the Guarantor’s obligations under this
Agreement and the other Loan Documents. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which
investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such
account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the
reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated, be applied to satisfy other obligations of the Borrower and the Guarantors under this Agreement or the other Loan
Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, and the Borrower is not otherwise required to pay to the Administrative Agent the excess attributable to
an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or
waived. 
 ARTICLE III 

Payments of Principal and Interest; Prepayments; Fees 

Section 3.01 Repayment of Loans. The Borrower hereby unconditionally promises to pay to the Administrative Agent for the
account of each Lender the then unpaid principal amount of each Loan on the Termination Date. 
 Section 3.02
Interest. 
 (a) ABR Loans. The Loans comprising each ABR Borrowing shall bear interest at the
Alternate Base Rate plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate. 
  

 48 

 (b) Eurodollar Loans. The Loans comprising each Eurodollar Borrowing
shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate. 

(c) Post-Default Rate. Notwithstanding the foregoing, during the continuance of an Event of Default the Majority
Lenders may, at their option, by notice to the Borrower, declare that (A) each Eurodollar Borrowing shall bear interest for the remainder of the applicable Interest Period at the Adjusted LIBO Rate plus the Applicable Margin plus 2% per
annum, (B) each ABR Borrowing shall bear interest at a rate per annum equal to the Alternate Base Rate in effect from time to time plus the Applicable Margin plus 2% per annum and (C) the fees described in Section 3.05(b) shall
be increased by 2% per annum, provided that, during the continuance of an Event of Default under Section 10.01(h) or Section 10.01(i), the interest rates set forth in clauses (A) and (B) above and the increase in the Letter
of Credit fee set forth in clause (C) above shall be applicable to all Borrowings without any election or action on the part of the Administrative Agent or any Lender. 

(d) Interest Payment Dates. Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date
for such Loan and on the Termination Date; provided that (i) interest accrued pursuant to Section 3.02(c) shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than an optional prepayment of
an ABR Loan prior to the Termination Date), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment, and (iii) in the event of any conversion of any Eurodollar Loan prior to the
end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion. 

(e) Interest Rate Computations. All interest hereunder shall be computed on the basis of a year of 360 days, unless
such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), except that interest computed by reference to the Alternate Base Rate at times when the
Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last
day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error, and be binding upon the parties hereto. 

Section 3.03 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

 (a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that
adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate for such Interest Period; or 

(b) the Administrative Agent is advised by the Majority Lenders that the Adjusted LIBO Rate or LIBO Rate, as applicable,
for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period; 

 

 49 

 then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by
telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that
requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made either as an ABR
Borrowing or at an alternate rate of interest determined by the Majority Lenders as their cost of funds. 
 Section 3.04
Prepayments. 
 (a) Optional Prepayments. Subject to any break funding costs payable pursuant to
Section 5.02 and prior notice in accordance with Section 3.04(b), the Borrower shall have the right at any time and from time to time to (i) prepay any ABR Borrowing in whole in or in part, in a minimum aggregate amount of $1,000,000
or any integral multiple of $500,000 in excess thereof or if less than $1,000,000, the remaining balance of the ABR Loans, and (ii) prepay any Eurodollar Borrowing in whole or in part, in a minimum aggregate amount of $3,000,000 or any integral
multiple of $500,000 in excess thereof or if less than $3,000,000, the remaining balance of such Eurodollar Borrowing. 

(b) Notice and Terms of Optional Prepayment. The Borrower shall notify the Administrative Agent by telephone
(confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York City time, three Business Days before the date of prepayment, or (ii) in the case of
prepayment of an ABR Borrowing, not later than 12:00 noon, New York City time, one Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or
portion thereof to be prepaid. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that
would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied
by accrued interest to the extent required by Section 3.02. 
 (c) Mandatory Prepayments. 

(i) If, after giving effect to any termination or reduction of the Aggregate Maximum Credit Amounts pursuant to
Section 2.06(b), the total Revolving Credit Exposures exceed the total Commitments, then the Borrower shall (A) prepay the Borrowings on the date of such termination or reduction in an aggregate principal amount equal to such excess, and
(B) if any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in
Section 2.08(i). 
 (ii) Upon any redetermination of or adjustment to the amount of the Borrowing Base in
accordance with Section 2.07 (other than Section 2.07(e)) or Section 8.13(c), if the total Revolving Credit Exposures exceed the redetermined or adjusted Borrowing Base, 

 

 50 

 
then the Borrower shall within 30 days after its receipt of a New Borrowing Base Notice give written notice to the Administrative Agent of the Borrower’s election to: (A) within 60 days
following its receipt of such New Borrowing Base Notice prepay the Loans in an aggregate principal amount equal to such excess (provided that all payments required to be made pursuant to this Section 3.04(c)(ii) must be made on or prior to the
Termination Date), (B) prepay the Loans in six (6) equal monthly installments, commencing on the day such election is made with each payment being equal to 1/6th of the aggregate principal amount of such excess (provided that all payments
required to be made pursuant to this Section 3.04(c)(ii) must be made on or prior to the Termination Date), (C) within 30 days following its receipt of such New Borrowing Base Notice, provide additional collateral in the form of additional
Oil and Gas Properties having proved reserves not evaluated in the most recently delivered Reserve Report or other collateral reasonably acceptable to the Administrative Agent having a Borrowing Base value (as proposed by the Administrative Agent
and approved by the Required Lenders) sufficient, after giving effect to any other actions taken pursuant to this Section 3.04(c)(ii) to eliminate any such excess or (D) undertake a combination of clauses (A), (B) and (C). If, because
of Letter of Credit Exposure, a Borrowing Base Deficiency remains after prepaying all of the Loans, the Borrower shall cash collateralize such remaining Borrowing Base Deficiency as provided in Section 2.08(i). 

(iii) Upon any adjustments to the Borrowing Base pursuant to Section 2.07(e), if the total Revolving Credit Exposures
exceed the Borrowing Base as adjusted, then the Borrower shall (A) prepay the Borrowings in an aggregate principal amount equal to such excess, and (B) if any excess remains after prepaying all of the Borrowings as a result of an LC
Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.08(j). The Borrower shall be obligated to make such prepayment and/or deposit of cash
collateral on the date it or any Subsidiary receives cash proceeds as a result of such termination, creation of offsetting positions or disposition, as applicable; provided that all payments required to be made pursuant to this
Section 3.04(c)(iii) must be made on or prior to the Termination Date. 
 (iv) Upon any adjustment to the
Borrowing Base pursuant to Section 9.05 or Section 9.12, if the total Revolving Credit Exposures exceeds the Borrowing Base as adjusted, then the Borrower shall (A) prepay the Borrowings in an aggregate principal amount equal to such
excess, and (B) if any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in
Section 2.08(i). The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral either on the date it or any Subsidiary receives cash proceeds as a result of such disposition; provided that all payments required to be
made pursuant to this Section 3.04(c)(iv) must be made on or prior to the Termination Date. 
 (v) Each
prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied, first, ratably to any ABR Borrowings then outstanding, and, second, to any Eurodollar Borrowings then outstanding, and if more than one Eurodollar Borrowing is then
outstanding, to each such Eurodollar Borrowing in order of priority beginning with the Eurodollar Borrowing with the least number of days remaining in the Interest Period applicable 

 

 51 

 
thereto and ending with the Eurodollar Borrowing with the most number of days remaining in the Interest Period applicable thereto. 

(vi) Each prepayment of Borrowings pursuant to this Section 3.04(b) shall be applied ratably to the Loans included in
the prepaid Borrowings. Prepayments pursuant to this Section 3.04(b) shall be accompanied by accrued interest to the extent required by Section 3.02. 

(d) No Premium or Penalty. Prepayments permitted or required under this Section 3.04 shall be without premium
or penalty, except as required under Section 5.02. 
 Section 3.05 Fees. 

(a) Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Lender a
commitment fee, which shall accrue at the rate per annum of 1.00% on the average daily amount of the unused amount of each Lender’s Applicable Percentage of the aggregate Commitments during the period from and including the date of this
Agreement to but excluding the Termination Date. Accrued commitment fees shall be payable in arrears on the last day of March, June, September and December of each year and on the Termination Date, commencing on the first such date to occur after
the date hereof. All commitment fees shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a
leap year), and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). 

(b) Letter of Credit Fees. The Borrower agrees to pay (i) to the Administrative Agent for the account of each
Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Margin used to determine the interest rate applicable to Eurodollar Loans on the average daily amount of such Lender’s
LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement to but excluding the later of the date on which such Lender’s Commitment terminates and
the date on which such Lender ceases to have any LC Exposure, (ii) to the Issuing Bank a fronting fee, which shall accrue at the rate of 0.25% per annum on the average daily amount of the LC Exposure (excluding any portion thereof
attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure,
provided that in no event shall such fee be less than $125 during any quarter, and (iii) to the Issuing Bank, for its own account, its standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or
processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable on the third Business Day following such last day, commencing on
the first such date to occur after the date of this Agreement; provided that all such fees shall be payable on the Termination Date and any such fees accruing after the Termination Date shall be payable on written demand. Any other fees payable to
the Issuing Bank pursuant to this Section 3.05(a) shall be payable within 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days, unless

  

 52 

 
such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the
actual number of days elapsed (including the first day but excluding the last day). 
 (c) Administrative
Agent Fees. The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times agreed upon between the Borrower and the Administrative Agent in the Fee Letter. 

ARTICLE IV 

Payments; Pro Rata Treatment; Sharing of Set-offs 

Section 4.01 Payments Generally; Pro Rata Treatment; Sharing of Set-offs. 

(a) Payments by the Borrower. The Borrower shall make each payment required to be made by it hereunder (whether of
principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 12:00 noon, New York City time, on the date when due, in immediately available
funds, without defense, deduction, recoupment, set-off or counterclaim. Fees, once paid, shall be fully earned and shall not be refundable under any circumstances. Any amounts received after such time on any date may, in the discretion of the
Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices specified in Section 12.01,
except payments to be made directly to the Issuing Bank as expressly provided herein and except that payments pursuant to Section 5.01, Section 5.02, Section 5.03 and Section 12.03 shall be made directly to the Persons entitled
thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a
Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in
dollars. 
 (b) Application of Insufficient Payments. If at any time insufficient funds are received by
and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due
hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably
among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties. 

(c) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or
otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations
in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) 

 

 53 

 
participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in
accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving
rise thereto is recovered, such participations shall be rescinded and the purchase price returned to the extent of such recovery, without interest, and (ii) the provisions of this Section 4.01(c) shall not be construed to apply to any
payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC
Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this Section 4.01(c) shall apply). The Borrower consents to the foregoing and agrees, to the extent
it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if
such Lender were a direct creditor of the Borrower in the amount of such participation. 
 Section 4.02 Presumption of
Payment by the Borrower. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank that the Borrower
will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be,
the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed
to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and
a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. 

Section 4.03 Payments and Deductions to a Defaulting Lender. 

(a) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.05(a),
Section 2.08(d), Section 2.08(e) or Section 4.02 then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account
of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid in cash. 

(b) If a Defaulting Lender (or a Lender who would be a Defaulting Lender but for the expiration of the relevant grace
period) as a result of the exercise of a set-off shall have received a payment in respect of its Revolving Credit Exposure which results in its Revolving Credit Exposure being less than its Applicable Percentage of the aggregate Revolving Credit
Exposures, then no payments will be made to such Defaulting Lender until such time as such Defaulting Lender shall have complied with Section 4.03(c) and all amounts due and owing to the Lenders has been equalized in accordance with each
Lender’s respective pro rata share of the 
  

 54 

 
Indebtedness. Further, if at any time prior to the acceleration or maturity of the Loans, the Administrative Agent shall receive any payment in respect of principal of a Loan or a reimbursement
of an LC Disbursement while one or more Defaulting Lenders shall be party to this Agreement, the Administrative Agent shall apply such payment first to the Borrowing(s) for which such Defaulting Lender(s) shall have failed to fund its pro rata share
until such time as such Borrowing(s) are paid in full or each Lender (including each Defaulting Lender) is owed its Applicable Percentage of all Loans then outstanding. After acceleration or maturity of the Loans, subject to the first sentence of
this Section 4.03(b), all principal will be paid ratably as provided in Section 10.02(d). 
 (c)
Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender: 

(i) Fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Lender pursuant to
Section 3.05. 
 (ii) The Commitment and Revolving Credit Exposure of such Defaulting Lender shall not be
included in determining whether all Lenders or the Majority Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 12.02(b)); provided that (i) any waiver, amendment or
modification requiring the consent of all Lenders pursuant to Section 12.02(b) (other than Section 12.02(b)(vii) or requiring the consent of each affected Lender pursuant to Section 12.02(b)(i), (iii), (iv) or (v) shall
require the consent of such Defaulting Lender (which for the avoidance of doubt would include any change to the Maturity Date applicable to such Defaulting Lender, decreasing or forgiving any principal or interest due to such Defaulting Lender, any
decrease of any interest rate applicable to Loans made by such Defaulting Lender (other than the waiving of post-default or Borrowing Base Deficiency interest rates) and any increase in such Defaulting Lender’s Commitment) and (ii) any
redetermination, whether an increase, decrease or affirmation, of the Borrowing Base shall occur without the participation of a Defaulting Lender, but the Commitment (i.e. the Applicable Percentage of the Borrowing Base) of a Defaulting
Lender may not be increased without the consent of such Defaulting Lender. 
 (iii) If any LC Exposure exists at
the time a Lender becomes a Defaulting Lender then: 
 (A) all or any part of such LC Exposure shall be
reallocated among the Non-Defaulting Lenders in accordance with their respective Applicable Percentages (for the purposes of such reallocation the Defaulting Lender’s Commitment shall be disregarded in determining the Non-Defaulting
Lender’s Applicable Percentage) but only to the extent (x) the sum of all Non-Defaulting Lenders’ Revolving Credit Exposures plus such Defaulting Lender’s LC Exposure does not exceed the total of all Non-Defaulting Lenders’
Commitments, (y) the conditions set forth in Section 6.02 are satisfied at such time and (z) the sum of each Non-Defaulting Lender’s Revolving Credit Exposure plus its reallocated share of such Defaulting Lender’s LC
Exposure does not exceed such Non-Defaulting Lender’s Commitment; 
  

 55 

 (B) if the reallocation described in clause (A) above cannot, or can
only partially, be effected, then the Borrower shall within one Business Day following notice by the Administrative Agent cash collateralize such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to
clause (A) above) in accordance with the procedures set forth in Section 10.02 for so long as such LC Exposure is outstanding; 

(C) if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to this
Section 4.03 then the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 3.05(b) with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC
Exposure is cash collateralized; 
 (D) if the LC Exposure of the Non-Defaulting Lenders is reallocated pursuant
to Section 4.03(c), then the fees payable to the Lenders pursuant to Section 3.05(a) and Section 3.05(b) shall be adjusted in accordance with such Non-Defaulting Lenders’ Applicable Percentages; or 

(E) if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to
Section 4.03(c)(iii), then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, all commitment fees that otherwise would have been payable to such Defaulting Lender (solely with respect to the portion of
such Defaulting Lender’s Commitment that was utilized by such LC Exposure) and letter of credit fees payable under Section 3.05(b) with respect to such Defaulting Lender’s LC Exposure shall be payable to the Issuing Bank until such LC
Exposure is cash collateralized and/or reallocated. 
 (d) So long as any Lender is a Defaulting Lender, the
Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure will be 100% covered by the Commitments of the Non-Defaulting Lenders and/or cash collateral will be provided by
the Borrower in accordance with Section 4.03(c), and participating interests in any such newly issued or increased Letter of Credit shall be allocated among Non-Defaulting Lenders in a manner consistent with Section 2.08(d) (and Defaulting
Lenders shall not participate therein). 
 (e) In the event that the Administrative Agent, the Borrower and the
Issuing Bank each agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the LC Exposure of the Lenders shall be readjusted to reflect the inclusion of such Lender’s
Commitment and on such date, if necessary as a result of a Loan funding pursuant to Section 2.08(e), such Lender shall purchase at par such of the Loans of the other Lenders as the Administrative shall determine may be necessary in order for
such Lender to hold such Loans in accordance with its Applicable Percentage. 
 Section 4.04 Disposition of
Proceeds. The Security Instruments contain an assignment by the Borrower and/or the Guarantors unto and in favor of the Administrative Agent for the benefit of the Lenders of all of the Borrower’s or each Guarantor’s interest in and to
production and all proceeds attributable thereto which may be produced from or allocated to the Mortgaged Property. The Security Instruments further provide in general for the application of such

  

 56 

 
proceeds to the satisfaction of the Indebtedness and other obligations described therein and secured thereby. Notwithstanding the assignment contained in such Security Instruments, until the
occurrence of an Event of Default, (a) the Administrative Agent and the Lenders agree that they will neither notify the purchaser or purchasers of such production nor take any other action to cause such proceeds to be remitted to the
Administrative Agent or the Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrower and its Restricted Subsidiaries and (b) the Lenders hereby authorize the Administrative Agent to take such actions as may be
necessary to cause such proceeds to be paid to the Borrower and/or such Restricted Subsidiaries. 
 ARTICLE V 

Increased Costs; Break Funding Payments; Taxes; Illegality 

Section 5.01 Increased Costs. 

(a) Eurodollar Changes in Law. If any Change in Law (other than a Change in Law with respect to Indemnified Taxes
or Other Taxes, which shall be governed exclusively by Section 5.03, or Excluded Taxes) shall: 
 (i)
impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO
Rate); or 
 (ii) impose on any Lender or the London interbank market any other condition affecting this
Agreement or Eurodollar Loans made by such Lender; 
 and the result of any of the foregoing shall be to increase the cost to such Lender of
making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or otherwise), then the Borrower will pay to
such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered. 

(b) Capital Requirements. If any Lender or the Issuing Bank determines that any Change in Law regarding capital
requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if any, as a consequence of this
Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the Issuing
Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company with
respect to capital adequacy), then from time to time the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the
Issuing Bank’s holding company for any such reduction suffered. 
 (c) Certificates. A certificate of
a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in Section 5.01(a) or (b) shall be delivered to the

  

 57 

 
Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate within
10 days after receipt thereof. 
 (d) Effect of Failure or Delay in Requesting Compensation. Failure
or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that the
Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section 5.01 for any increased costs or reductions incurred more than 365 days prior to the date that such Lender or the Issuing Bank, as the case may
be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise
to such increased costs or reductions is retroactive, then the 365-day period referred to above shall be extended to include the period of retroactive effect thereof. 

Section 5.02 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than
on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan into an ABR Loan other than on the last day of the Interest Period applicable thereto, or
(c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense
attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have
accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor
(or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest
rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. 

A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section 5.02 shall be
delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. 

Section 5.03 Taxes. 

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower or any
Guarantor under any Loan Document shall be made free and clear of and without deduction or withholding for any Indemnified Taxes or Other Taxes; provided that if the Borrower or any Guarantor shall be required by applicable law to deduct or withhold
any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions or withholdings (including deductions or withholdings applicable to additional sums
payable under this Section 5.03(a)), the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an 
  

 58 

 
amount equal to the sum it would have received had no such deductions or withholdings been made, (ii) the Borrower or such Guarantor shall make such deductions or withholdings and
(iii) the Borrower or such Guarantor shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. 

(b) Payment of Other Taxes by the Borrower. The Borrower shall pay any Other Taxes to the relevant Governmental
Authority in accordance with applicable law. 
 (c) Indemnification by the Borrower. The Borrower shall
indemnify the Administrative Agent, each Lender and the Issuing Bank, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as the
case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 5.03) and any
penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate of the
Administrative Agent, a Lender or the Issuing Bank as to the amount of such payment or liability under this Section 5.03(c) shall be delivered to the Borrower and shall be conclusive absent manifest error. 

(d) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the
Borrower or a Guarantor to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting
such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. 
 (e)
Status of Lenders and Issuing Bank. Any Foreign Lender or Foreign Issuing Bank that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located or is resident for tax
purposes, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement or any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by
applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate. In addition, any Lender, if
requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to
determine whether or not such Lender is subject to backup withholding or information reporting requirements. 
 Without limiting
the generality of the foregoing, each Foreign Lender and Foreign Issuing Bank shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Foreign Lender or Foreign Issuing Bank becomes a Lender or Issuing Bank
under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent, but only if such Foreign Lender or Foreign Issuing Bank is legally entitled to do so), whichever of the following is
applicable: 
  

 59 

 (i) two (2) properly completed and executed IRS Forms W-8BEN claiming
eligibility for benefits of an income tax treaty to which the United States of America is a party, 
 (ii) two
(2) properly completed and executed IRS Forms W-8ECI, 
 (iii) in the case of a Foreign Lender claiming the
benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (B) a
“10 percent shareholder” of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) two (2) properly
completed and executed IRS Forms W-8BEN, 
 (iv) two (2) properly completed and executed Forms W-8IMY
(together with forms listed under clauses (i) through (iii) or (v) hereof, as may be required), or 

(v) any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal
withholding tax properly completed and executed together with any supplementary documentation as may be prescribed by applicable law to permit the Borrower and the Administrative Agent to determine the withholding or deduction required to be made.

 (f) Tax Refunds. If the Administrative Agent or a Lender or Issuing Bank determines, in its sole
discretion, that it has received a refund of any Indemnified Taxes or Other Taxes as to which it has been indemnified by the Borrower or any Guarantor or with respect to which the Borrower or any Guarantor has paid additional amounts pursuant to
this Section 5.03, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower or such Guarantor under this Section 5.03 with respect to the Indemnified
Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender or Issuing Bank and without interest (other than any interest paid by the relevant Governmental Authority with respect to
such refund); provided, that the Borrower, upon the request of the Administrative Agent or such Lender or Issuing Bank, agrees to repay the amount paid over to the Borrower or any Guarantor (plus any penalties, interest or other charges imposed by
the relevant Governmental Authority) to the Administrative Agent or such Lender or Issuing Bank in the event the Administrative Agent or such Lender or Issuing Bank is required to repay such refund to such Governmental Authority. This
Section 5.03 shall not be construed to require the Administrative Agent or any Lender or Issuing Bank to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other
Person. 
 Section 5.04 Mitigation Obligations; Replacement of Lenders. 

(a) Designation of Different Lending Office. If any Lender requests compensation under Section 5.01, or
if any Credit Party is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender or indemnify any 

 

 60 

 
Lender pursuant to Section 5.03, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in the reasonable judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 5.01 or
Section 5.03, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs
and expenses incurred by any Lender in connection with any such designation or assignment. 
 (b) Replacement
of Lenders. If any Lender requests compensation under Section 5.01, or if any Credit Party is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender or indemnify any Lender pursuant
to Section 5.03, or if any Lender becomes a Defaulting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in
accordance with and subject to the restrictions contained in Section 12.04(b)), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender
accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount
equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued
interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 5.01 or payments required to be made pursuant to Section 5.03,
such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances
entitling the Borrower to require such assignment and delegation cease to apply. 
 Section 5.05 Illegality.
Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its applicable lending office to honor its obligation to make or maintain Eurodollar Loans either generally or having a particular
Interest Period hereunder, then (a) such Lender shall promptly notify the Borrower and the Administrative Agent thereof and such Lender’s obligation to make such Eurodollar Loans shall be suspended (the “Affected Loans”)
until such time as such Lender may again make and maintain such Eurodollar Loans and (b) all Affected Loans which would otherwise be made by such Lender shall be made instead as ABR Loans (and, if such Lender so requests by notice to the
Borrower and the Administrative Agent, all Affected Loans of such Lender then outstanding shall be automatically converted into ABR Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans are so made as (or
converted into) ABR Loans, all payments of principal which would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its ABR Loans.

 ARTICLE VI 

Conditions Precedent 

Section 6.01 Effective Date. The obligations of the Lenders to make Loans and of the Issuing Bank to issue Letters of Credit
hereunder shall not become effective until the date on which each of the following conditions is satisfied (or waived in accordance with Section 12.02): 

(a) The Administrative Agent, the Arrangers and the Lenders shall have received all commitment, facility and agency fees
and all other fees and amounts due and payable on or prior to the Effective Date, including, to the extent invoiced, reimbursement or payment of all out-of-pocket expenses required to be reimbursed or paid by the Borrower hereunder (including,
without limitation, the fees and expenses of Vinson & Elkins L.L.P., counsel to the Administrative Agent).

ARTICLE VII 

Representations and Warranties 

The Borrower represents and warrants to the Lenders that: 

Section 7.01 Organization; Powers. Each of the Borrower and the Restricted Subsidiaries is duly organized, validly existing
and in good standing under the laws of the jurisdiction of its organization, has all requisite power and authority, and has all material governmental licenses, authorizations, consents and approvals necessary, to own its assets and to carry on its
business as now conducted, and is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required, except where failure to have such power, authority, licenses, authorizations, consents, approvals and
qualifications could not reasonably be expected to have a Material Adverse Effect. 
 Section 7.02 Authority;
Enforceability. The Transactions are within the Borrower’s and each Guarantor’s corporate powers and have been duly authorized by all necessary corporate and, if required, stockholder action (including, without limitation, any action
required to be taken by any class of directors of the Borrower or any other Person, whether interested or disinterested, in order to ensure the due authorization of the Transactions). Each Loan Document to which the Borrower and each Guarantor is a
party has been duly executed and delivered by the Borrower and such Guarantor and constitutes a legal, valid and binding obligation of the Borrower and 

 

 65 

 
such Guarantor, as applicable, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights
generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law. 

Section 7.03 Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or
filing with, or any other action by, any Governmental Authority or any other third Person (including shareholders or any class of directors, whether interested or disinterested, of the Borrower or any other Person), nor is any such consent,
approval, registration, filing or other action necessary for the validity or enforceability of any Loan Document or the consummation of the transactions contemplated thereby, except such as have been obtained or made and are in full force and effect
other than (i) the recording and filing of the Security Instruments as required by this Agreement and (ii) those third party approvals or consents which, if not made or obtained, would not cause a Default hereunder, could not reasonably be
expected to have a Material Adverse Effect or do not have an adverse effect on the enforceability of the Loan Documents, (b) will not violate any applicable law or regulation or the charter, by-laws or other Organizational Documents of the
Borrower or any Restricted Subsidiary or any order of any Governmental Authority, (c) will not violate or result in a default under any indenture, agreement or other instrument binding upon the Borrower or any Restricted Subsidiary or its
Properties, or give rise to a right thereunder to require any payment to be made by the Borrower or such Restricted Subsidiary and (d) will not result in the creation or imposition of any Lien on any Property of the Borrower or any Restricted
Subsidiary (other than the Liens created by the Loan Documents). 
 Section 7.04 Financial Condition; No Material
Adverse Change. 
 (a) The Borrower has heretofore furnished to the Lenders its consolidated balance sheet
and statements of operations, stockholders’ equity and comprehensive income (loss), and cash flows as of and for the fiscal year ended December 31, 2009, reported on by the Borrower’s independent public accountants, certified by its
chief financial officer. Such financial statements present fairly, in all material respects, the financial position and results of operations and cash flows of the Borrower and its Consolidated Subsidiaries as of such date and for such fiscal year
in accordance with GAAP. 
 (b) Since December 31, 2009, (i) there has been no event, development or
circumstance that has had or could reasonably be expected to have a Material Adverse Effect and (ii) the business of the Borrower and its Restricted Subsidiaries has been conducted only in the ordinary course consistent with past business
practices. 
 (c) Neither the Borrower nor any Restricted Subsidiary has on the date hereof any material Debt
(including Disqualified Capital Stock) or any contingent liabilities, off-balance sheet liabilities or partnerships, liabilities for taxes, unusual forward or long-term commitments or unrealized or anticipated losses from any unfavorable
commitments, except as referred to or reflected or provided for in the Financial Statements or otherwise disclosed to the Administrative Agent and the Lenders in writing. 
  

 66 

 Section 7.05 Litigation. Except as set forth on Schedule 7.05, there are no
actions, suits, investigations or proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of the Borrower, threatened against or affecting the Borrower or any Restricted Subsidiary (i) not fully
covered by insurance (except for normal deductibles) as to which there is a reasonable possibility of an adverse determination that, if adversely determined, could reasonably be expected, individually or in the aggregate, to result in a Material
Adverse Effect or (ii) that involve any Loan Document or the Transactions. 
 Section 7.06 Environmental
Matters. Except for such matters as set forth on Schedule 7.06 or that, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect: 

(a) the Borrower and the Subsidiaries and each of their respective Properties and operations thereon are, and within all
applicable statute of limitation periods have been, in compliance with all applicable Environmental Laws. 
 (b)
the Borrower and the Subsidiaries have obtained all Environmental Permits required for their respective operations and each of their Properties, with all such Environmental Permits being currently in full force and effect, and none of Borrower or
the Subsidiaries has received any written notice or otherwise has knowledge that any such existing Environmental Permit will be revoked or that any application for any new Environmental Permit or renewal of any existing Environmental Permit will be
protested or denied. 
 (c) there are no claims, demands, suits, orders, inquiries, or proceedings concerning any
violation of, or any liability (including as a potentially responsible party) under, any applicable Environmental Laws that is pending or, to Borrower’s knowledge, threatened against the Borrower or any Subsidiary or any of their respective
Properties or as a result of any operations at such Properties. 
 (d) none of the Properties of the Borrower or
any Subsidiary contain or have contained any: (i) underground storage tanks; (ii) asbestos-containing materials; (iii) landfills or dumps; (iv) hazardous waste management units as defined pursuant to RCRA or any comparable state
law; or (v) sites on or nominated for the National Priority List promulgated pursuant to CERCLA or any state remedial priority list promulgated or published pursuant to any comparable state law. 

(e) there has been no Release or, to the Borrower’s knowledge, threatened Release, of Hazardous Materials at, on,
under or from the Borrower’s or any Subsidiary’s Properties, there are no investigations, remediations, abatements, removals, or monitorings of Hazardous Materials required under applicable Environmental Laws at such Properties and, to the
knowledge of the Borrower, none of such Properties are adversely affected by any Release or threatened Release of a Hazardous Material originating or emanating from any other real property. 

(f) neither the Borrower nor any Subsidiary has received any written notice asserting an alleged liability or obligation
under any applicable Environmental Laws with respect to the investigation, remediation, abatement, removal, or monitoring of any Hazardous Materials 

 

 67 

 
at, under, or Released or threatened to be Released from any real properties offsite the Borrower’s or any Subsidiary’s Properties and there are no conditions or circumstances that
could reasonably be expected to result in the receipt of such written notice. 
 (g) there has been no exposure
of any Person or Property to any Hazardous Materials as a result of or in connection with the operations and businesses of any of the Borrower’s or the Subsidiaries’ Properties that could reasonably be expected to form the basis for a
claim for damages or compensation. 
 (h) The Borrower and the Subsidiaries have provided to the Lenders complete
and correct copies of all environmental site assessment reports, investigations, studies, analyses, and correspondence on environmental matters (including matters relating to any alleged non-compliance with or liability under Environmental Laws)
that are in any of the Borrower’s or the Subsidiaries’ possession or control and relating to their respective Properties or operations thereon. 

Section 7.07 Compliance with the Laws and Agreements; No Defaults. 

(a) Each of the Borrower and each Restricted Subsidiary is in compliance with all Governmental Requirements applicable to
it or its Property and all agreements and other instruments binding upon it or its Property, and possesses all licenses, permits, franchises, exemptions, approvals and other governmental authorizations necessary for the ownership of its Property and
the conduct of its business, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. 

(b) Neither the Borrower nor any Restricted Subsidiary is in default nor has any event or circumstance occurred which, but
for the expiration of any applicable grace period or the giving of notice, or both, would constitute a default or would require the Borrower or a Restricted Subsidiary to Redeem or make any offer to Redeem under any indenture, note, credit agreement
or instrument (including, without limitation, the Indenture and the Second Lien Notes) pursuant to which any Material Indebtedness is outstanding or by which the Borrower or any Restricted Subsidiary or any of their Properties is bound. 

(c) No Default has occurred and is continuing. 

Section 7.08 Investment Company Act. Neither the Borrower nor any Subsidiary is an “investment company” or a
company “controlled” by an “investment company,” within the meaning of, or subject to regulation under, the Investment Company Act of 1940, as amended. 

Section 7.09 Taxes. Each of the Borrower and its Subsidiaries has timely filed or caused to be filed all Tax returns and
reports required to have been filed by or with respect to it and has paid or caused to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate proceedings and for which the
Borrower or such Subsidiary, as applicable, has set aside on its books adequate reserves in accordance with GAAP or (b) to the extent that the failure to do so could not reasonably be expected to result in a Material Adverse Effect. The
charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of Taxes and other governmental charges are, in the reasonable opinion of the Borrower, adequate. No Tax Lien has been filed and, to the knowledge of the

  

 68 

 
Borrower, no claim is being asserted with respect to any such Tax or other such governmental charge. 

Section 7.10 Employee Benefit Plans. 

(a) The Borrower, the Subsidiaries and each ERISA Affiliate have complied in all material respects with ERISA and, where
applicable, the Code regarding each Plan. 
 (b) Except as disclosed on Schedule 7.10, each Plan is, and has
been, established and maintained in substantial compliance with its terms, ERISA and, where applicable, the Code. 

(c) No act, omission or transaction has occurred which could result in imposition on the Borrower, any Subsidiary or any
ERISA Affiliate (whether directly or indirectly) of (i) either a civil penalty assessed pursuant to subsections (c), (i), (l) or (m) of section 502 of ERISA or a tax imposed pursuant to Chapter 43 of Subtitle D of the Code or
(ii) breach of fiduciary duty liability damages under section 409 of ERISA, except as where such penalty or damages would not have a Material Adverse Effect. 

(d) Full payment when due has been made of all amounts which the Borrower, the Subsidiaries or any ERISA Affiliate is
required under the terms of each Plan or applicable law to have paid as contributions to such Plan as of the date hereof, except where a failure would not have a Material Adverse Effect or any amount being contested in good faith and pursuant to
appropriate action being pursued diligently. 
 (e) Except as disclosed in Schedule 7.10, neither the Borrower,
the Subsidiaries nor any ERISA Affiliate sponsors, maintains, or contributes to an employee welfare benefit plan, as defined in section 3(1) of ERISA, including, without limitation, any such plan maintained to provide benefits to former employees of
such entities, that may not be terminated by the Borrower, a Subsidiary or any ERISA Affiliate in its sole discretion at any time without any material liability. 

(f) Neither the Borrower, the Subsidiaries nor any ERISA Affiliate sponsors, maintains or contributes to, or has at any
time in the six-year period preceding the date hereof sponsored, maintained or contributed to, any employee pension benefit plan, as defined in section 3(2) of ERISA, that is subject to Title IV of ERISA, section 302 of ERISA or section 412 of the
Code. 
 (g) Each Foreign Pension Plan is in compliance in all material respects with all requirements of law
applicable thereto and the respective requirements of the governing documents for such plan. With respect to each Foreign Pension Plan, none of the Borrower, its Affiliates or any of their respective directors, officers, employees or agents has
engaged in a transaction that could subject the Borrower or any Subsidiary, directly or indirectly, to a tax or civil penalty that could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect. With respect
to each Foreign Pension Plan, reserves have been established in the financial statements furnished to the Lenders in respect of any unfunded liabilities in accordance with applicable law and prudent business practice or, where required, in
accordance with ordinary accounting practices in the jurisdiction in which such Foreign Pension 
  

 69 

 
Plan is maintained. The aggregate unfunded liabilities with respect to such Foreign Pension Plans could not reasonably be expected to result in a Material Adverse Effect; the present value of the
aggregate accumulated benefit liabilities of all such Foreign Pension Plans (based on those assumptions used to fund each such Foreign Pension Plan) did not, as of the last annual valuation date applicable thereto, exceed by more than $25,000,000
the Fair Market Value of the assets of all such Foreign Pension Plans. 
 Section 7.11 Disclosure; No Material
Misstatements. The Borrower has disclosed to the Administrative Agent and the Lenders all agreements, instruments and corporate or other restrictions to which it or any of its Restricted Subsidiaries is subject, and all other matters known to
it, that, individually or in the aggregate, could reasonably be expected to result in a Material Adverse Effect. None of the reports, financial statements, certificates or other information furnished by or on behalf of the Borrower or any Restricted
Subsidiary to the Administrative Agent or any Lender or any of their Affiliates in connection with the negotiation of this Agreement or any other Loan Document or delivered hereunder or under any other Loan Document (as modified or supplemented by
other information so furnished) contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that,
with respect to projected financial information, the Borrower represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time. There is no fact peculiar to the Borrower or any Restricted
Subsidiary which could reasonably be expected to have a Material Adverse Effect or in the future is reasonably likely to have a Material Adverse Effect and which has not been set forth in this Agreement or the Loan Documents or the other documents,
certificates and statements furnished to the Administrative Agent or the Lenders by or on behalf of the Borrower or any Restricted Subsidiary prior to, or on, the date hereof in connection with the transactions contemplated hereby. There are no
statements or conclusions in any Reserve Report which are based upon or include misleading information or fail to take into account material information regarding the matters reported therein, it being understood that projections concerning volumes
attributable to the Oil and Gas Properties of the Borrower and the Restricted Subsidiaries and production and cost estimates contained in each Reserve Report are necessarily based upon professional opinions, estimates and projections and that the
Borrower and the Restricted Subsidiaries do not warrant that such opinions, estimates and projections will ultimately prove to have been accurate. 

Section 7.12 Insurance. The Borrower has, and has caused all of its Restricted Subsidiaries to have, (a) all insurance
policies sufficient for the compliance by each of them with all material Governmental Requirements and all material agreements and (b) insurance coverage in at least amounts and against such risk (including, without limitation, public
liability) that are usually insured against by companies similarly situated and engaged in the same or a similar business for the assets and operations of the Borrower and its Restricted Subsidiaries. The Administrative Agent and the Lenders have
been named as additional insureds in respect of such liability insurance policies and the Administrative Agent has been named as loss payee with respect to Property loss insurance. 

Section 7.13 Restriction on Liens. Neither the Borrower nor any of the Restricted Subsidiaries is a party to any material
agreement or arrangement, or subject to any order, judgment, writ or decree, which either restricts or purports to restrict its ability to grant Liens to 

 

 70 

 
the Administrative Agent and the Lenders on or in respect of their Properties to secure the Indebtedness and the Loan Documents, other than the Indenture and the Intercreditor Agreement.

 Section 7.14 Subsidiaries; Foreign Operations. Except as set forth on Schedule 7.14 or as disclosed in writing to
the Administrative Agent (which shall promptly furnish a copy to the Lenders), which shall be a supplement to Schedule 7.14, the Borrower has no Subsidiaries and the Borrower has no Restricted Subsidiaries. Schedule 7.14 identifies each
Subsidiary as either Restricted or Unrestricted, and each Restricted Subsidiary on such schedule is a Wholly-Owned Subsidiary. 

Section 7.15 Location of Business and Offices. The Borrower’s jurisdiction of organization is Texas; the name of the
Borrower as listed in the public records of its jurisdiction of organization is ATP Oil & Gas Corporation; and the organizational identification number of the Borrower in its jurisdiction of organization is 0120230900 (or, in each case, as
set forth in a notice delivered to the Administrative Agent pursuant to Section 8.01(l) in accordance with Section 12.01). The Borrower’s principal place of business and chief executive offices are located at the address specified in
Section 12.01 (or as set forth in a notice delivered pursuant to Section 8.01(l) and in accordance with Section 12.01). Each Restricted Subsidiary’s jurisdiction of organization, name as listed in the public records of its
jurisdiction of organization, organizational identification number in its jurisdiction of organization, and the location of its principal place of business and chief executive office is stated on Schedule 7.15 (or as set forth in a notice
delivered pursuant to Section 8.01(l) accordance with Section 12.01). 
 Section 7.16 Properties; Titles,
Etc. 
 (a) Each of the Borrower and the Restricted Subsidiaries has good and defensible title to the Oil and
Gas Properties evaluated in the most recently delivered Reserve Report and good title to all its personal Properties, in each case, free and clear of all Liens except Liens permitted by Section 9.03. After giving full effect to the Excepted
Liens, the Borrower or the Restricted Subsidiary specified as the owner owns the net interests in production attributable to the Hydrocarbon Interests as reflected in the most recently delivered Reserve Report, and the ownership of such Properties
shall not in any material respect obligate the Borrower or such Restricted Subsidiary to bear the costs and expenses relating to the maintenance, development and operations of each such Property in an amount in excess of the working interest of each
Property set forth in the most recently delivered Reserve Report that is not offset by a corresponding proportionate increase in the Borrower’s or such Restricted Subsidiary’s net revenue interest in such Property. The quantum and nature
of the interest of the Borrower and the Subsidiaries in and to the Oil and Gas Properties as set forth in each Reserve Report includes or will include the entire interest of the Borrower and the Subsidiaries in such Oil and Gas Properties as of the
date of such Reserve Report and are or will be complete and accurate in all material respects as of the date of such Reserve Report; and there are no “back-in” or “reversionary” interests held by third parties which could reduce
the interest of the Borrower and the Subsidiaries in such Oil and Gas Properties in any material respect, except as expressly set forth or given effect to in such Reserve Report. 

(b) All material licenses, leases and agreements necessary for the conduct of the business of the Borrower and the
Restricted Subsidiaries are valid and subsisting, in full force 
  

 71 

 
and effect, and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such lease or leases, which
could reasonably be expected to have a Material Adverse Effect. 
 (c) The rights and Properties presently owned,
leased or licensed by the Borrower and the Restricted Subsidiaries including, without limitation, all easements and rights of way, include all rights and Properties necessary to permit the Borrower and the Restricted Subsidiaries to conduct their
business in all material respects in the same manner as its business has been conducted prior to the date hereof. 

(d) All of the Properties of the Borrower and the Restricted Subsidiaries which are reasonably necessary for the operation
of their businesses are in good working condition and are maintained in accordance with prudent business standards. 

(e) The Borrower and each Restricted Subsidiary owns, or is licensed to use, all trademarks, tradenames, copyrights,
patents and other intellectual Property material to its business, and the use thereof by the Borrower and such Restricted Subsidiary does not infringe upon the rights of any other Person, except for any such infringements that, individually or in
the aggregate, could not reasonably be expected to result in a Material Adverse Effect. The Borrower and its Restricted Subsidiaries either own or have valid licenses or other rights to use all databases, geological data, geophysical data,
engineering data, seismic data, maps, interpretations and other technical information used in their businesses as presently conducted, subject to the limitations contained in the agreements governing the use of the same, which limitations are
customary for companies engaged in the business of the exploration and production of Hydrocarbons, with such exceptions as could not reasonably be expected to have a Material Adverse Effect. 

Section 7.17 Maintenance of Properties. Except for such acts or failures to act as could not be reasonably expected to have a
Material Adverse Effect, the Oil and Gas Properties (and Properties unitized therewith) of the Borrower and its Restricted Subsidiaries have been maintained, operated and developed in a good and workmanlike manner and in conformity with all
Governmental Requirements and in conformity with the provisions of all leases, subleases or other contracts comprising a part of the Hydrocarbon Interests and other contracts and agreements forming a part of the Oil and Gas Properties of the
Borrower and its Restricted Subsidiaries. Specifically in connection with the foregoing, except for those as could not be reasonably expected to have a Material Adverse Effect, (i) no Oil and Gas Property of the Borrower or any Restricted
Subsidiary is subject to having allowable production reduced below the full and regular allowable (including the maximum permissible tolerance) because of any overproduction (whether or not the same was permissible at the time) and (ii) none of
the wells comprising a part of the Oil and Gas Properties (or Properties unitized therewith) of the Borrower or any Restricted Subsidiary is deviated from the vertical more than the maximum permitted by Governmental Requirements, and such wells are,
in fact, bottomed under and are producing from, and the well bores are wholly within, the Oil and Gas Properties (or in the case of wells located on Properties unitized therewith, such unitized Properties) of the Borrower or such Restricted
Subsidiary. All pipelines, wells, gas processing plants, platforms and other material improvements, fixtures and equipment owned in whole or in part by the Borrower or any of its Restricted Subsidiaries that are necessary to conduct normal
operations are being 
  

 72 

 
maintained in a state adequate to conduct normal operations, and with respect to such of the foregoing which are operated by the Borrower or any of its Restricted Subsidiaries, in a manner
consistent with the Borrower’s or its Restricted Subsidiaries’ past practices (other than those the failure of which to maintain in accordance with this Section 7.17 could not reasonably be expected to have a Material Adverse Effect).

 Section 7.18 Prepayments. Except as set forth on Schedule 7.18 or on the most recent Reserve Report Certificate,
on a net basis there are no take or pay or other prepayments which would require the Borrower or any of its Restricted Subsidiaries to deliver Hydrocarbons produced from their Oil and Gas Properties at some future time without then or thereafter
receiving full payment therefor. 
 Section 7.19 Marketing of Production. Except for contracts listed on Schedule
7.19 and in effect on the date hereof, and thereafter either disclosed in writing to the Administrative Agent or included in the most recently delivered Reserve Report (with respect to all of which contracts the Borrower represents that it or its

(c) With the delivery of each Reserve Report, the Borrower shall provide to the Administrative Agent and the Lenders a
Reserve Report Certificate certifying that in all material respects: (i) the information contained in the Reserve Report and any other information delivered in connection therewith is true and correct, (ii) the Borrower or its Restricted
Subsidiaries owns good and defensible title to the Oil and Gas Properties evaluated in such Reserve Report and such Properties are free of all Liens except for Liens permitted by Section 9.03, (iii) except as set forth on an exhibit to the
certificate, on a net basis there are no take or pay or other prepayments, with respect to its Oil and Gas Properties evaluated in such Reserve Report which would require the Borrower or any Restricted Subsidiary to deliver Hydrocarbons either
generally or produced from such Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor, (iv) none of their Oil and Gas Properties have been sold since the date of the last Borrowing Base
determination except as set forth on an exhibit to the certificate, which certificate shall list all of its Oil and Gas Properties sold and in such detail as reasonably required by the Administrative Agent, (v) attached to the certificate is a
list of all marketing agreements entered into subsequent to the later of the date hereof or the most recently 
  

 81 

 
delivered Reserve Report which the Borrower could reasonably be expected to have been obligated to list on Schedule 7.19 had such agreement been in effect on the date hereof and
(vi) attached thereto is a schedule of the Oil and Gas Properties evaluated by such Reserve Report that are Mortgaged Properties and demonstrating the percentage of the PV-10 Value of the Oil and Gas Properties that the value of such Mortgaged

 Section 8.13 Title Information. 

(a) On or before the delivery to the Administrative Agent and the Lenders of each Reserve Report required by
Section 8.12(a), the Borrower will deliver title information in form and substance acceptable to the Administrative Agent covering enough of the Oil and Gas Properties evaluated by such Reserve Report that were not included in the immediately
preceding Reserve Report, so that the Administrative Agent shall have received together with title information previously delivered to the Administrative Agent, satisfactory title information on at least 80% of the PV-10 Value of the Oil and Gas
Properties evaluated by such Reserve Report and located in, or in U.S. Federal waters adjacent to, the United States. 

(b) If the Borrower has provided title information for additional Properties under Section 8.13(a), the Borrower
shall, within 60 days of notice from the Administrative Agent that title defects or exceptions exist with respect to such additional Properties, either (i) cure any such title defects or exceptions (including defects or exceptions as to
priority) which are not permitted by Section 9.03 raised by such information, (ii) substitute acceptable Mortgaged Properties with no title defects or exceptions except for Excepted Liens (other than Excepted Liens described in clauses
(e), (g) and (h) of such definition) having an equivalent value or (iii) deliver title information in form and substance acceptable to the Administrative Agent so that the Administrative Agent shall have received, together with title
information previously delivered to the Administrative Agent, satisfactory title information on at least 80% of the PV-10 Value of the Oil and Gas Properties evaluated by such Reserve Report and located in, or in U.S. Federal waters adjacent to, the
United States. 
 (c) If the Borrower is unable to cure any title defect requested by the Administrative Agent or
the Lenders to be cured within the 60-day period or the Borrower does not comply with the requirements to provide acceptable title information covering 80% of the PV-10 Value of the Oil and Gas Properties evaluated in the most recent Reserve Report
and located in, or in U.S. Federal waters adjacent to, the United States, such default shall not be a Default, but instead the Administrative Agent and/or the Required Lenders shall have the right to exercise the following remedy in their sole
discretion from time to time, and any failure to so exercise this remedy at any time shall not be a waiver as to future exercise of the remedy by the Administrative Agent or the Lenders. To the extent that the Administrative Agent or the Required
Lenders are not satisfied with title to any Mortgaged Property after the 60-day period has elapsed, such unacceptable Mortgaged Property shall not count towards the 80% requirement, and the Administrative Agent may send a notice to the Borrower and
the Lenders that the then outstanding Borrowing Base shall be reduced by an amount as determined by the Required Lenders to cause the Borrower to be in compliance with the requirement to provide acceptable title information on 80% of the PV-10 Value
of the Oil and Gas Properties evaluated 
  

 82 

 
by such Reserve Report and located in, or in U.S. Federal waters adjacent to, the United States. This new Borrowing Base shall become effective immediately after receipt of such notice.

 Section 8.14 Additional Collateral; Additional Guarantors. 

(a) In connection with each redetermination of the Borrowing Base, the Borrower shall review the Reserve Report and the
list of current Mortgaged Properties (as described in Section 8.12(c)(vi)) to ascertain whether the Mortgaged Properties represent at least 80% of the PV-10 Value of the Oil and Gas Properties evaluated in the most recently completed Reserve
Report and located in, or in U.S. Federal waters adjacent to, the United States, after giving effect to exploration and production activities, acquisitions, dispositions and production. In the event that the Mortgaged Properties do not represent at
least 80% of such total value, then the Borrower shall, and shall cause its Restricted Subsidiaries to, grant, within thirty (30) days of delivery of the Reserve Report Certificate, to the Administrative Agent as security for the Indebtedness a
first-priority Lien interest (provided that Excepted Liens may exist, but subject to the provisos at the end of such definition) on additional Oil and Gas Properties not already subject to a Lien of the Security Instruments such that after giving
effect thereto, the Mortgaged Properties will represent at least 80% of such PV-10 Value of the Oil and Gas Properties located in, or in U.S. Federal waters adjacent to, the United States. All such Liens will be created and perfected by and in
accordance with the provisions of deeds of trust, security agreements and financing statements or other Security Instruments, all in form and substance reasonably satisfactory to the Administrative Agent and in sufficient executed (and acknowledged
where necessary or appropriate) counterparts for recording purposes. In order to comply with the foregoing, if any Restricted Subsidiary places a Lien on its Oil and Gas Properties and such Restricted Subsidiary is not a Guarantor, then it shall
become a Guarantor and comply with Section 8.14(b). 
 (b) In the event that (i) the Borrower
determines that any Restricted Subsidiary is a Material Domestic Subsidiary or (ii) any Domestic Subsidiary (other than an Unrestricted Subsidiary) incurs or guarantees any Debt, the Borrower shall promptly cause such Restricted Subsidiary to
guarantee the Indebtedness pursuant to the Guarantee and Collateral Agreement. In connection with any such guaranty, the Borrower shall, or shall cause such Restricted Subsidiary to, (A) execute and deliver a supplement to the Guarantee and
Collateral Agreement executed by such Subsidiary, (B) pledge all of the Capital Stock of such new Subsidiary (including, without limitation, delivery of original stock certificates evidencing the Capital Stock of such Subsidiary, together with
an appropriate undated stock powers for each certificate duly executed in blank by the registered owner thereof) owned by the Borrower or such Material Domestic Subsidiary and (C) execute and deliver such other additional closing documents,
certificates and legal opinions as shall reasonably be requested by the Administrative Agent. 
 (c) In the event
that the Borrower or any Domestic Subsidiary becomes the owner of a Material Foreign Subsidiary, then the Borrower shall promptly, or shall cause such Domestic Subsidiary to promptly, pledge Capital Stock representing 65% of the total combined
voting power of all classes of stock entitled to vote and 100% of any other class of stock of such Material Foreign Subsidiary (including, without limitation, delivery of original stock certificates evidencing such Capital Stock of such Material
Foreign Subsidiary, together with appropriate 
  

 83 

 
stock powers for each certificate duly executed in blank by the registered owner thereof) owned by the Borrower or such Domestic Subsidiary and execute and deliver such other additional closing

 (xi) 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 Agreement which are materially no less favorable to the Borrower and its Restricted Subsidiaries than those that would have been

Section 9.17 Swap Agreement. 

(a) The Borrower will not, and will not permit any Subsidiary to, enter into any Swap Agreements with any Person other
than (i) Swap Agreements in respect of commodities (A) with an Approved Counterparty, (B) the notional volumes for which (when aggregated with other commodity Swap Agreements then in effect other than puts, floors and basis
differential swaps on volumes already hedged pursuant to other Swap Agreements) do not exceed, as of the date such Swap Agreement is executed, 85% of the reasonably anticipated projected production from Oil and Gas Properties which are proved,
developed and producing as of the date such Swap Agreement is entered, for each month (other than August, September and October solely with respect to Oil and Gas Properties located in the Gulf of Mexico) during the period for which such Swap
Agreement is in effect for each of crude oil and natural gas, calculated separately; provided that during the months of August, September and October solely with respect to Oil and Gas Properties located in the Gulf of Mexico, the notional volumes
for such Swap Agreements (when aggregated with other commodity Swap Agreements then in effect other than puts, floors and basis differential swaps on volumes already hedged pursuant to other Swap Agreements) shall not exceed, as of the date such
Swap Agreement is executed, 50% of the reasonably anticipated projected production from Oil and Gas Properties which are proved, developed and producing as of the date such Swap Agreement is entered for each such month for each of crude oil and
natural gas, calculated separately, and (C) the tenor of which is not more than 60 months from the date such Swap Agreement is executed, and (ii) Swap Agreements in respect of interest rates with an Approved Counterparty, as follows:
(A) Swap Agreements 
  

 96 

 
effectively converting interest rates from fixed to floating, the notional amounts of which (when aggregated with all other Swap Agreements of the Borrower and its Subsidiaries then in effect
effectively converting interest rates from fixed to floating) do not exceed 75% of the then outstanding principal amount of the Borrower’s Debt for borrowed money which bears interest at a fixed rate and (B) Swap Agreements effectively
converting interest rates from floating to fixed, the notional amounts of which (when aggregated with all other Swap Agreements of the Borrower and its Subsidiaries then in effect effectively converting interest rates from floating to fixed) do not
exceed 75% of the then outstanding principal amount of the Borrower’s Debt for borrowed money which bears interest at a floating rate. For the avoidance of doubt, Swap Agreements entered into as of the Effective Date and disclosed on Schedule
7.20 hereto shall not be included in the calculation of the 85% and 50% limits set forth in this Section 9.17(a). 

(b) The Borrower shall maintain the hedge positions established by any Swap Agreements used in determining any Borrowing
Base during the periods of such Swap Agreements; provided that, if the Borrower sells, assigns, terminates or unwinds any such Swap Agreements and the effect of such action (when taken together with any other Swap Agreement executed
contemporaneously with the taking of such action) has the effect of cancelling the positions under such Swap Agreements, then the Borrower shall provide the Administrative Agent written notice of such termination and the Borrowing Base shall be
adjusted in accordance with Section 2.07(e) . 
 (c) The Borrower shall not enter into any Swap Agreement
for speculative purposes. It is understood that for purposes of this Section 9.17, the following Swap Agreements shall not be deemed speculative or entered into for speculative purposes: (i) any commodity Swap Agreement intended, at
inception of execution, to hedge or manage any of the risks related to existing and or forecasted Hydrocarbon production of the Borrower or its Restricted Subsidiaries (whether or not contracted) and (ii) any Swap Agreement intended, at
inception of execution, (A) to hedge or manage the interest rate exposure associated with any debt securities, debt facilities or leases (existing or forecasted) of the Borrower or its Restricted Subsidiaries, (B) for foreign exchange or
currency exchange management, (C) to manage commodity portfolio exposure associated with changes in interest rates or (D) to hedge any exposure that the Borrower or its Restricted Subsidiaries may have to counterparties under other Swap
Agreements such that the combination of such Swap Agreements is not speculative taken as a whole. 
 Section 9.18
Designation and Conversion of Restricted and Unrestricted Subsidiaries; Debt of Unrestricted Subsidiaries. 

(a) Schedule 7.14 sets forth all the Restricted Subsidiaries. Unless designated as an Unrestricted Subsidiary on Schedule
7.14 as of the date hereof or thereafter, assuming compliance with Section 9.18(b), any Person that becomes a Subsidiary of the Borrower or any of its Restricted Subsidiaries shall be classified as a Restricted Subsidiary. 

(b) The Borrower may designate any Subsidiary (including any newly acquired or newly formed Subsidiary or a Person
becoming a Subsidiary through merger or consolidation or Investment therein) to be an Unrestricted Subsidiary only if (1) such Subsidiary is an Infrastructure Subsidiary and substantially concurrently with such designation such Infrastructure
Subsidiary (or any Infrastructure Subsidiary owned by it, directly or indirectly 
  

 97 

 
through one or more subsidiaries) receives debt and/or equity financing from a third party that is not the Borrower, a Restricted Subsidiary of the Borrower or an Affiliate of the Borrower or any
Restricted Subsidiary, or (2) such Subsidiary satisfies the following requirements: 
 (i) such Subsidiary
or any of its subsidiaries does not own any Capital Stock or Debt of or have any Investment in, or own or hold any Lien on any property of, any other subsidiary of the Borrower which is not a subsidiary of the subsidiary to be so designated or
otherwise an Unrestricted Subsidiary; 
 (ii) all the Debt of such Subsidiary and its subsidiaries shall, at the
date of designation, and will at all times thereafter, consist of Non-Recourse Debt; 
 (iii) on the date of such
designation, such designation and the Investment of the Borrower or the Restricted Subsidiary in such Subsidiary complies with Section 9.04(a); 

(iv) such Subsidiary is a Person with respect to which neither the Borrower nor any of its Restricted Subsidiaries has any
direct or indirect obligation: 
 (A) to subscribe for additional Capital Stock of such Person; or 

(B) to maintain or preserve such Person’s financial condition or to cause such Person to achieve any specified
levels of operating results; 
 (v) on the date such Subsidiary is designated an Unrestricted Subsidiary, such
Subsidiary is not a party to any agreement, contract, arrangement or understanding with the Borrower or any Restricted Subsidiary with terms substantially less favorable to the Borrower than those that might have been obtained from Persons who are
not Affiliates of the Borrower; and 
 (vi) prior, and after giving effect, to such designation, neither a
Default nor a Borrowing Base deficiency would exist. 
 (c) Any such designation by the Borrower shall be
evidenced by written notice to the Administrative Agent giving effect to such designation and a certificate of Financial Officer certifying that such designation complies with the foregoing conditions. If, at any time, any Unrestricted Subsidiary
would fail to meet the foregoing requirements as an Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of this Agreement and any Debt of such Subsidiary shall be deemed to be Incurred as of such date.

 (d) The Borrower may designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that
immediately after giving effect to such designation, no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof.

ARTICLE XI 

The Agents 

Section 11.01 Appointment; Powers. Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative
Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof and the other Loan Documents, together with such actions and
powers as are reasonably incidental thereto. 
 Section 11.02 Duties and Obligations of Administrative Agent. The
Administrative Agent shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other
implied duties, regardless of whether a Default has occurred and is continuing (the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent is not intended to connote any fiduciary or other
implied (or express) obligations arising under agency doctrine of any applicable law; rather, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent
contracting parties), (b) the Administrative Agent shall have no duty to take any discretionary action or exercise any discretionary powers, except as provided in Section 11.03, and (c) except as expressly set forth herein, the
Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is 

 

 102 

 
communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall be deemed not to have knowledge of any Default
unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in
connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or under any other Loan Document or in connection herewith or therewith, (iii) the performance or
observance of any of the covenants, agreements or other terms or conditions set forth herein or in any other Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other
agreement, instrument or document, (v) the satisfaction of any condition set forth in Article VI or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent or as to those
conditions precedent expressly required to be to the Administrative Agent’s satisfaction, (vi) the existence, value, perfection or priority of any collateral security or the financial or other condition of the Borrower and its Subsidiaries
or any other obligor or guarantor, or (vii) any failure by the Borrower or any other Person (other than itself) to perform any of its obligations hereunder or under any other Loan Document or the performance or observance of any covenants,
agreements or other terms or conditions set forth herein or therein. For purposes of determining compliance with the conditions specified in Article VI, each Lender shall be deemed to have consented to, approved or accepted or to be satisfied with,
each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received written notice from such Lender prior to the proposed closing date
specifying its objection thereto. 
 Section 11.03 Action by Administrative Agent. The Administrative Agent shall
have no duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise in writing
as directed by the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) and in all cases the Administrative Agent shall be fully justified in failing or
refusing to act hereunder or under any other Loan Documents unless it shall (a) receive written instructions from the Majority Lenders or the Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary under
the circumstances as provided in Section 12.02) specifying the action to be taken and (b) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of taking or
continuing to take any such action. The instructions as aforesaid and any action taken or failure to act pursuant thereto by the Administrative Agent shall be binding on all of the Lenders. If a Default has occurred and is continuing, then the
Administrative Agent shall take such action with respect to such Default as shall be directed by the requisite Lenders in the written instructions (with indemnities) described in this Section 11.03, provided that, unless and until the
Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best
interests of the Lenders. In no event, however, shall the Administrative Agent be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, the Loan Documents or applicable law.
If a Default has occurred and is continuing, neither the 
  

 103 

 
Syndication Agent nor the Documentation Agent shall have any obligation to perform any act in respect thereof. The Administrative Agent shall not be liable for any action taken or not taken by it
with the consent or at the request of the Majority Lenders or the Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02), and otherwise the Administrative Agent
shall not be liable for any action taken or not taken by it hereunder or under any other Loan Document or under any other document or instrument referred to or provided for herein or therein or in connection herewith or therewith INCLUDING ITS OWN
ORDINARY NEGLIGENCE, except for its own gross negligence or willful misconduct. 
 Section 11.04 Reliance by
Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be
genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for
relying thereon and each of the Borrower, the Lenders and the Issuing Bank hereby waives the right to dispute the Administrative Agent’s record of such statement, except in the case of gross negligence or willful misconduct by the
Administrative Agent. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in
accordance with the advice of any such counsel, accountants or experts. The Administrative Agent may deem and treat the payee of any Note as the holder thereof for all purposes hereof unless and until a written notice of the assignment or transfer
thereof permitted hereunder shall have been filed with the Administrative Agent. 
 Section 11.05 Subagents. The
Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its
duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding Sections of this Article XI shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and
any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. 

Section 11.06 Resignation or Removal of Administrative Agent. Subject to the appointment and acceptance of a successor
Administrative Agent as provided in this Section 11.06, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrower, and the Administrative Agent may be removed at any time with or without cause
by the Majority Lenders. Upon any such resignation or removal, the Majority Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Majority Lenders and shall have
accepted such appointment within 30 days after the retiring Agent gives notice of its resignation or removal of the retiring Agent, then the retiring Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Agent which shall be
a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers,

  

 104 

 
privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Agent shall be
the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Agent’s resignation hereunder, the provisions of this Article XI and Section 12.03 shall continue in effect for the
benefit of such retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Agent. 

Section 11.07 Agents as Lenders. Each bank serving as an Agent hereunder shall have the same rights and powers in its
capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any
Subsidiary or other Affiliate thereof as if it were not an Agent hereunder. 
 Section 11.08 No Reliance.

 (a) Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent,
any other Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and each other Loan Document to which it is a party. Each Lender
also acknowledges that it will, independently and without reliance upon the Administrative Agent, any other Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document, any related agreement or any document furnished hereunder or thereunder. The Agents shall not be required to keep themselves informed as to the
performance or observance by the Borrower or any of its Subsidiaries of this Agreement, the Loan Documents or any other document referred to or provided for herein or to inspect the Properties or books of the Borrower or its Subsidiaries. Except for
notices, reports and other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder, no Agent or the Arrangers shall have any duty or responsibility to provide any Lender with any credit or
other information concerning the affairs, financial condition or business of the Borrower (or any of its Affiliates) which may come into the possession of such Agent or any of its Affiliates. In this regard, each Lender acknowledges that
Vinson & Elkins L.L.P. is acting in this transaction as special counsel to the Administrative Agent only, except to the extent otherwise expressly stated in any legal opinion or any Loan Document. Each other party hereto will consult with
its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein. 

(b) The Lenders acknowledge that the Administrative Agent and the Arrangers are acting solely in administrative capacities
with respect to the structuring and syndication of this facility and have no duties, responsibilities or liabilities under this Agreement and the other Loan Documents other than their administrative duties, responsibilities and liabilities
specifically as set forth in the Loan Documents and in their capacity as Lenders hereunder. In structuring, arranging or syndicating this facility, each Lender acknowledges that the Administrative Agent and/or Arrangers may be an agent or lender
under these Notes, the Second Lien Notes, other loans or other securities and waives any existing or future conflicts of 

 

 105 

 
interest associated with the their role in such other debt instruments. If in its administration of this facility or any other debt instrument, the Administrative Agent determines (or is given
written notice by any Lender that a conflict exists), then it shall eliminate such conflict within 90 days or resign pursuant to Section 11.06 and shall have no liability for action taken or not taken while such conflict existed. 

Section 11.09 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Borrower or any of its Subsidiaries, the Administrative Agent (irrespective of whether the principal of any Loan shall then be
due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise:

 (a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect
of the Loans and all other Indebtedness that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under Section 12.03) allowed in such
judicial proceeding; and 
 (b) to collect and receive any monies or other property payable or deliverable on any
such claims and to distribute the same; 
 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in
any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the
Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Section 12.03.

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

 Section 11.10 Authority of Administrative Agent to Release Collateral and Release or Subordinate Liens. Each
Lender and the Issuing Bank hereby authorizes the Administrative Agent to release or subordinate, to the rights of the transferee of any such collateral, its Liens against any collateral that is permitted to be sold or released pursuant to the terms
of the Loan Documents. Each Lender and the Issuing Bank hereby authorizes the Administrative Agent to execute and deliver to the Borrower, at the Borrower’s sole cost and expense, any and all releases of Liens, termination statements,
assignments or other documents reasonably requested by the Borrower in connection with any sale or other disposition of Property to the extent such 

 

 106 

 
sale or other disposition is permitted by the terms of Section 9.12 or is otherwise authorized by the terms of the Loan Documents. 

Section 11.11 The Arrangers, the Syndication Agent and the Documentation Agent. The Arrangers, the Syndication Agent and the
Documentation Agent shall have no duties, responsibilities or liabilities under this Agreement and the other Loan Documents other than their duties, responsibilities and liabilities in their capacity as Lenders hereunder.

 Section 12.02 Waivers; Amendments. 

(a) No failure on the part of the Administrative Agent, any other Agent, the Issuing Bank or any Lender to exercise and no
delay in exercising, and no course of dealing with 
  

 107 

 
respect to, any right, power or privilege, or any abandonment or discontinuance of steps to enforce such right, power or privilege, under any of the Loan Documents shall operate as a waiver
thereof, nor shall any single or partial exercise of any right, power or privilege under any of the Loan Documents preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies of the
Administrative Agent, any other Agent, the Issuing Bank and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this
Agreement or any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by Section 12.02(b), and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the
Administrative Agent, any other Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time. 

(b) Neither this Agreement nor any provision hereof nor any Security Instrument nor any provision thereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Majority Lenders; provided that no such agreement shall (i) increase the Commitment or the Maximum Credit Amount of any Lender
without the written consent of such Lender, (ii) increase the Borrowing Base without the written consent of each Lender, decrease or maintain the Borrowing Base without the consent of the Required Lenders, or modify Section 2.07 in any
manner without the consent of each Lender; provided that a Scheduled Redetermination may be postponed by the Required Lenders, (iii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce
any fees payable hereunder, or reduce any other Indebtedness hereunder or under any other Loan Document, without the written consent of each Lender affected thereby, (iv) postpone the scheduled date of payment or prepayment of the principal
amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or any other Indebtedness hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or postpone or extend the
Termination Date without the written consent of each Lender affected thereby, (v) change Section 4.01(b) or Section 4.01(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of
each Lender, (vi) waive or amend Section 3.04(b), Section 6.01, Section 8.14, Section 10.02(d) or Section 12.14 without the written consent of each Lender, (vii) release any Guarantor (except as set forth in the
Guarantee and Collateral Agreement), release all or substantially all of the collateral (other than as provided in Section 11.10), or reduce the percentage set forth in Section 8.14(a) without the written consent of each Lender,
(viii) change any of the provisions of this Section 12.02(b) or the definitions of “Required Lenders” or “Majority Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive,
amend or modify any rights hereunder or under any other Loan Documents or make any determination or grant any consent hereunder or any other Loan Documents, without the written consent of each Lender; provided further that no such agreement shall
amend, modify or otherwise affect the rights or duties of the Administrative Agent, any other Agent, or the Issuing Bank hereunder or under any other Loan Document without the prior written consent of the Administrative Agent, such other Agent or
the Issuing Bank, as the case may be, or (ix) waive any failure to maintain the financial covenants set forth in Section 9.01(a), Section 9.01(b) or Section 9.01(c) during the period ending March 31, 2011 without the written

  

 108 

 
consent of each Lender. Notwithstanding the foregoing, any supplement to Schedule 7.14 (Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental schedule
clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders. 

Section 12.03 Expenses, Indemnity; Damage Waiver. 

(a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent, the
Arrangers and their Affiliates, including, without limitation, the reasonable fees, charges and disbursements of counsel and other outside consultants for the Administrative Agent, the reasonable travel, photocopy, mailing, courier, telephone and
other similar expenses, and the cost of environmental invasive and non-invasive assessments and audits and surveys and appraisals, in connection with the syndication of the credit facilities provided for herein, the preparation, negotiation,

Agreement and the other Loan Documents and any amendments, modifications or waivers of or consents related to the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all
costs, expenses, Taxes, assessments and other charges incurred by any Agent or any Lender in connection with any filing, registration, recording or perfection of any security interest contemplated by this Agreement or any Security Instrument or any
other document referred to therein, (iii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder,
(iv) all reasonable out-of-pocket expenses incurred by any Agent, the Issuing Bank or any Lender, including, without limitation, the fees, charges and disbursements of any counsel for any Agent, the Issuing Bank or any Lender, in connection
with the enforcement or protection of its rights in connection with this Agreement or any other Loan Document, including, without limitation, its rights under this Section 12.03, or in connection with the Loans made or Letters of Credit issued
hereunder, including, without limitation, all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit. 

(b) THE BORROWER SHALL INDEMNIFY EACH AGENT, THE ARRANGERS, THE ISSUING BANK AND EACH LENDER, AND EACH RELATED PARTY OF
ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON BEING CALLED AN “INDEMNITEE”) AGAINST, AND DEFEND AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, PENALTIES, LIABILITIES AND RELATED EXPENSES, INCURRED BY
OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF ANY CLAIM, LITIGATION, PROCEEDING OR INVESTIGATION, INCLUDING ANY CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING BROUGHT BY THE BORROWER OR ANY SUBSIDIARY,
RELATING TO: 
 (i) THE EXECUTION OR DELIVERY OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY OR
THEREBY, THE PERFORMANCE BY THE PARTIES HERETO OR THE PARTIES TO ANY OTHER LOAN DOCUMENT OF THEIR RESPECTIVE OBLIGATIONS HEREUNDER OR THEREUNDER OR THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREBY OR BY ANY OTHER LOAN DOCUMENT, (ii) THE
FAILURE OF THE BORROWER OR 
  

 109 

 
ANY SUBSIDIARY TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING THIS AGREEMENT, (iii) ANY LOAN OR LETTER OF CREDIT OR THE USE OF THE PROCEEDS THEREFROM, INCLUDING, WITHOUT
LIMITATION, (A) ANY REFUSAL BY THE ISSUING BANK TO HONOR A DEMAND FOR PAYMENT UNDER A LETTER OF CREDIT IF THE DOCUMENTS PRESENTED IN CONNECTION WITH SUCH DEMAND DO NOT STRICTLY COMPLY WITH THE TERMS OF SUCH LETTER OF CREDIT, OR (B) THE
PAYMENT OF A DRAWING UNDER ANY LETTER OF CREDIT NOTWITHSTANDING THE NON-COMPLIANCE, NON-DELIVERY OR OTHER IMPROPER PRESENTATION OF THE DOCUMENTS PRESENTED IN CONNECTION THEREWITH, (iv) ANY ASSERTION THAT THE LENDERS WERE NOT ENTITLED TO RECEIVE
THE PROCEEDS RECEIVED PURSUANT TO THE SECURITY INSTRUMENTS, (v) ANY ENVIRONMENTAL LAW APPLICABLE TO THE BORROWER OR ANY SUBSIDIARY OR ANY OF THEIR PROPERTIES OR OPERATIONS, INCLUDING, THE PRESENCE, GENERATION, STORAGE, RELEASE, THREATENED
RELEASE, USE, TRANSPORT, DISPOSAL, ARRANGEMENT OF DISPOSAL OR TREATMENT OF HAZARDOUS MATERIALS ON OR AT ANY OF THEIR PROPERTIES, (vi) THE BREACH OR NON-COMPLIANCE BY THE BORROWER OR ANY SUBSIDIARY WITH ANY ENVIRONMENTAL LAW APPLICABLE TO THE
BORROWER OR ANY SUBSIDIARY, (vii) THE PRESENCE, USE, RELEASE, STORAGE, TREATMENT, DISPOSAL, GENERATION, THREATENED RELEASE, TRANSPORT, ARRANGEMENT FOR TRANSPORT OR ARRANGEMENT FOR DISPOSAL OF HAZARDOUS MATERIALS ON OR AT ANY OF THE PROPERTIES
OWNED OR OPERATED BY THE BORROWER OR ANY SUBSIDIARY OR ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF HAZARDOUS MATERIALS ON OR FROM ANY PROPERTY OWNED OR OPERATED BY THE BORROWER OR ANY OF ITS SUBSIDIARIES, (viii) ANY ENVIRONMENTAL LIABILITY
RELATED IN ANY WAY TO THE BORROWER OR ANY OF ITS SUBSIDIARIES, OR (ix) ANY OTHER ENVIRONMENTAL, HEALTH OR SAFETY CONDITION IN CONNECTION WITH THE LOAN DOCUMENTS, OR (x) ANY CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING RELATING TO ANY OF
THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY AND REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO, AND SUCH INDEMNITY SHALL EXTEND TO EACH INDEMNITEE NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND OR
CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING, WITHOUT LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF ONE OR MORE OF THE INDEMNITEES OR BY REASON
OF STRICT LIABILITY IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNITEES; PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES OR RELATED EXPENSES ARE
DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILFUL MISCONDUCT OF SUCH INDEMNITEE. 

(c) To the extent that the Borrower fails to pay any amount required to be paid by it to any Agent, the Arrangers or the
Issuing Bank under Section 12.03(a) or (b), each Lender severally agrees to pay to such Agent, the Arrangers or the Issuing Bank, as the case may be, such Lender’s Applicable Percentage (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against such Agent,
the Arrangers or the Issuing Bank in its capacity as such. 
  

 110 

 (d) To the extent permitted by applicable law, the Borrower shall not
assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this
Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof. 

(e) All amounts due under this Section 12.03 shall be payable promptly after written demand therefor. 

Section 12.04 Successors and Assigns. 

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder
without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder
except in accordance with this Section 12.04. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any
Affiliate of the Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in Section 12.04(c)) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing
Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement. 

(b)(i) Subject to the conditions set forth in Section 12.04(b)(ii), any Lender may assign to one or more assignees
all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of: 

(A) the Borrower, provided that no consent of the Borrower shall be required if such assignment is to a Lender, an
Affiliate of a Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, is to any other assignee; and 

(B) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment to
an assignee that is a Lender immediately prior to giving effect to such assignment. 
 (ii) Assignments shall be
subject to the following additional conditions: 
 (A) except in the case of an assignment to a Lender or an
Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the
Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, provided that no

  

 111 

 
such consent of the Borrower shall be required if an Event of Default has occurred and is continuing; 

(B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s
rights and obligations under this Agreement; 
 (C) the parties to each assignment shall execute and deliver to
the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and 

(D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

 (iii) Subject to Section 12.04(b)(iv) and the acceptance and recording thereof, from and after the
effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of
the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits and subject to the obligations of Section 5.01, Section 5.02,
Section 5.03 and Section 12.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.04 shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with Section 12.04(c). 
 (iv) The
Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders,
and the Maximum Credit Amount of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the
Borrower, the Administrative Agent, the Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the
contrary. The Register shall be available for inspection by the Borrower, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice. In connection with any changes to the Register, if necessary, the
Administrative Agent will reflect the revisions on Annex I and forward a copy of such revised Annex I to the Borrower, the Issuing Bank and each Lender. 

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the
assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in Section 12.04(b) and any written consent to such assignment required by
Section 12.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall 

 

 112 

 
be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 12.04(b). 

(c) (i) Any Lender may, without the consent of the Borrower, the Administrative Agent or the Issuing Bank, sell
participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it);
provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower,
the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to
which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or
instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the proviso to Section 12.02 that affects such Participant. In addition such agreement must
provide that the Participant be bound by the provisions of Section 12.03. Subject to Section 12.04(c)(ii), the Borrower agrees that each Participant shall be entitled to the benefits of Section 5.01, Section 5.02 and
Section 5.03 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.04(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.08
as though it were a Lender, provided such Participant agrees to be subject to Section 4.01(c) as though it were a Lender. 

(ii) A Participant shall not be entitled to receive any greater payment under Section 5.01 or Section 5.03 than
the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent (which consent, if
any, expressly acknowledges any additional obligations of the Borrower in respect of Indemnified Taxes or Other Taxes). A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 5.03
unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 5.03(e) as though it were a Lender. 

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this
Agreement to secure obligations of such Lender, including, without limitation, any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section 12.04(d) shall not apply to any such pledge or assignment of a security
interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. 

(e) Notwithstanding any other provisions of this Section 12.04, no transfer or assignment of the interests or
obligations of any Lender or any grant of participations therein shall be permitted if such transfer, assignment or grant would require the Borrower and the 

 

 113 

 
Guarantors to file a registration statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any state. 

Section 12.05 Survival; Revival; Reinstatement. 

(a) All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making
of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, any other Agent, the Issuing Bank or any Lender may have had notice
or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other
amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Section 5.01, Section 5.02, Section 5.03 and
Section 12.03 and Article XI shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the
Commitments or the termination of this Agreement, any other Loan Document or any provision hereof or thereof. 

(b) To the extent that any payments on the Indebtedness or proceeds of any collateral are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law, common law or equitable cause, then to such extent, the Indebtedness so satisfied
shall be revived and continue as if such payment or proceeds had not been received and the Administrative Agent’s and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and each Loan Document shall
continue in full force and effect. In such event, each Loan Document shall be automatically reinstated and the Borrower shall take such action as may be reasonably requested by the Administrative Agent and the Lenders to effect such reinstatement.

 Section 12.06 Counterparts; Integration; Effectiveness. 

(a) This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of
which shall constitute an original, but all of which when taken together shall constitute a single contract. 

(b) This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the
Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof and
thereof. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES HERETO AND THERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT

  

 114 

 
ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. 

(c) Except as provided in Section 6.01, this Agreement shall become effective when it shall have been executed by the
Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement. 

Section 12.07 Severability. Any provision of this Agreement or any other Loan Document held to be invalid, illegal or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof or
thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. 

Section 12.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its
Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations
(of whatsoever kind, including, without limitations obligations under Swap Agreements) at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower or any Restricted Subsidiary against any of and all the
obligations of the Borrower or any Restricted Subsidiary owed to such Lender now or hereafter existing under this Agreement or any other Loan Document, irrespective of whether or not such Lender shall have made any demand under this Agreement or any
other Loan Document and although such obligations may be unmatured. The rights of each Lender under this Section 12.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender or its Affiliates may have.

(a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK. 
 (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS SHALL BE BROUGHT IN THE COURTS OF
THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PARTY HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS PROPERTY,
GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH
IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND DOES NOT PRECLUDE A 

 

 115 

 
PARTY FROM OBTAINING JURISDICTION OVER ANOTHER PARTY IN ANY COURT OTHERWISE HAVING JURISDICTION. 

(c) EACH PARTY IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR

only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement. 

Section 12.11 Confidentiality. Each of the Administrative Agent, the Issuing Bank and the Lenders agrees to maintain the
confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being
understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority or any
self-regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement or any other Loan Document, (e) in connection with the
exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement
containing provisions substantially the same as those of this Section 12.11, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any
actual or prospective counterparty (or its advisors) to any Swap Agreement relating to the Borrower and its 
  

 116 

 
obligations, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section 12.11
or (ii) becomes available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis from a source other than the Borrower. For the purposes of this Section 12.11, “Information” means all
information received from the Borrower or any Restricted Subsidiary relating to the Borrower or any Restricted Subsidiary and their businesses, other than any such information that is available to the Administrative Agent, the Issuing Bank or any
Lender on a nonconfidential basis prior to disclosure by the Borrower or a Restricted Subsidiary; provided that, in the case of information received from the Borrower or any Restricted Subsidiary after the date hereof, such information is clearly
identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section 12.11 shall be considered to have complied with its obligation to do so if such Person has
exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information. 

Section 12.12 Interest Rate Limitation. It is the intention of the parties hereto that each Lender shall conform strictly to
usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be usurious as to any Lender under laws applicable to it (including the laws of the United States of America and the State of New York or any other jurisdiction
whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any of the Loan Documents or any agreement entered into in connection
with or as security for the Notes, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under law applicable to any Lender that is contracted for, taken, reserved, charged or received by such Lender under
any of the Loan Documents or agreements or otherwise in connection with the Notes shall under no circumstances exceed the maximum amount allowed by such applicable law, and any excess shall be canceled automatically and if theretofore paid shall be
credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Borrower); and (ii) in the
event that the maturity of the Notes is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such
consideration that constitutes interest under law applicable to any Lender may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled
automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness
shall have been or would thereby be paid in full, refunded by such Lender to the Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by law applicable
to such Lender, be amortized, prorated, allocated and spread throughout the stated term of the Loans evidenced by the Notes until payment in full so that the rate or amount of interest on account of any Loans hereunder does not exceed the maximum
amount allowed by such applicable law. If at any time and from time to time (i) the amount of interest payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to such Lender pursuant to this Section 12.12
and (ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to such Lender would be less than the amount of interest payable to such Lender 

 

 117 

 
computed at the Highest Lawful Rate applicable to such Lender, then the amount of interest payable to such Lender in respect of such subsequent interest computation period shall continue to be
computed at the Highest Lawful Rate applicable to such Lender until the total amount of interest payable to such Lender shall equal the total amount of interest which would have been payable to such Lender if the total amount of interest had been
computed without giving effect to this Section 12.12. 
 Section 12.13 EXCULPATION PROVISIONS. EACH OF THE
PARTIES HERETO SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ
THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING ITS
EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR
ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.” 

Section 12.14 Collateral Matters; Swap Agreements. The benefit of the Security Instruments and of the provisions of this
Agreement relating to any collateral securing the Indebtedness shall also extend to and be available to those Lenders or their Affiliates which are counterparties to any Swap Agreement with the Borrower or any of its Subsidiaries on a pro
rata basis in respect of any obligations of the Borrower or any of its Subsidiaries which arise under any such Swap Agreement while such Person or its Affiliate is a Lender, but only while such Person or its Affiliate is a Lender, including any
Swap Agreements between such Persons in existence prior to the date hereof; provided that if a Person or its Affiliate ceases to be a Lender solely because the Revolving Credit Exposures have been paid in full and the Commitments terminated, then
the Liens securing such Swap Agreements shall continue in favor of such Person until those obligations are paid in full in cash or otherwise expire or are terminated. No Lender or any Affiliate of a Lender shall have any voting rights under any Loan
Document as a result of the existence of obligations owed to it under any such Swap Agreements. 
 Section 12.15 No
Third Party Beneficiaries. This Agreement, the other Loan Documents, and the agreement of the Lenders to make Loans and the Issuing Bank to issue, amend, renew or extend Letters of Credit hereunder are solely for the benefit of the Borrower, and
no other Person (including, without limitation, any Subsidiary of the Borrower, any obligor, contractor, subcontractor, supplier or materialsman) shall have any rights, claims, remedies or privileges hereunder or under any other Loan Document
against the Administrative Agent, any other Agent, the Issuing Bank or any Lender for any reason whatsoever. There are no third party beneficiaries.

 Section 12.16 USA Patriot Act Notice. Each Lender hereby notifies the Borrower
that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which
information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act.
