 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. On the Effective Date (or as soon as practicable with
respect to (iii)): 
 (i) the Borrower shall pay all accrued and unpaid commitment fees, break funding fees under
Section 5.02 and all other fees that are outstanding under the Existing Credit Agreement for the account of each “Lender” under the Existing Credit Agreement; 
 (ii) each “ABR Loan” and “Eurodollar Loan” outstanding under the Existing Credit Agreement shall be deemed to be
repaid with the proceeds of a new ABR Loan or Eurodollar Loan, as applicable, under this Agreement; 
 (iii) the
Administrative Agent shall use reasonable efforts to cause such “Lender” under the Existing Credit Agreement to deliver to the Borrower as soon as practicable after the Effective Date the Note issued by the Borrower to it under the

 22 

 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. 
 (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
$1,000,000 and not less than $1,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than $1,000,000; provided that an ABR Borrowing may be in an
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 8 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. Each
Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and
paid to such Lender from time to time hereunder. The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the
amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each
Lender’s share thereof. The entries made in the accounts maintained pursuant to this Section 2.02(d) shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any
Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement. Any Lender may request that Loans made
by it be evidenced by a Note. In such event, the Borrower shall prepare, execute and deliver to such Lender a Note payable to the order of such Lender and substantially in the form of Exhibit A dated, in the case of (i) any Lender party hereto
as of the date of this 

  

 23 

 
Agreement, as of the date of this Agreement or (ii) any Lender that becomes a party hereto pursuant to an Assignment and Assumption, as of the effective
date of the Assignment and Assumption, payable to the order of such Lender in a principal amount equal to its Maximum Credit Amount as in effect on such date, and otherwise duly completed. Thereafter, the Loans evidenced by such Note and interest
thereon shall at all times (including after assignment pursuant to Section 12.04) be represented by one or more Notes in such form payable to the order of the payee named therein (or, if such Note is a registered note, to such payee and its
registered assigns). 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 the order of 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, fax (or transmit by electronic communication, if arrangements for doing so have been
approved by the Administrative Agent) (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 12:00 noon, New York City time, one Business Day before the date of the proposed 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 (or electronic communication) 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, electronic communication, and written Borrowing Request shall specify the following information in compliance with Section 2.02: 
 (i) the aggregate amount of the requested Borrowing; 
 (ii) the date of such Borrowing, which shall be a Business Day; 
 (iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; 
 (iv) in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by
the definition of the term “Interest Period”; 
  

 24 

 (v) the amount of the then effective 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 
 (vi) 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 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, fax (or transmit by electronic
communication, if arrangements for doing so have been approved by the Issuing Bank) 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 (or electronic communication) 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, electronic communication 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)(iii) and (iv) shall be specified for each resulting Borrowing); 
  

 25 

 (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 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 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
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 1:00 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 and
designated by the 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.

 (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 

  

 26 

 
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
with interest thereon, 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. 
 Section 2.06
Termination and Reduction 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 or the Borrowing Base is terminated or reduced to zero, then the Commitments shall terminate on the effective date of such
termination or reduction. 
 (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; provided that (A) each
reduction of the Aggregate Maximum Credit Amounts shall be in an amount that is an integral multiple of $5,000,000 and not less than $10,000,000 and (B) the Borrower shall not terminate or reduce the Aggregate Maximum Credit Amounts if, after
giving effect to any concurrent prepayment of the Loans in accordance with Section 3.04(c), 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; provided that a notice of termination of the Aggregate Maximum Credit Amounts delivered by the Borrower
may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such
condition is not satisfied. 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. 
 Section 2.07 Borrowing Base. 
 (a) Initial Borrowing Base. For the period from and including the Effective Date to but excluding the next Redetermination Date, the amount of the
Borrowing Base shall be $1,100,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments from time to time pursuant to Section 2.07(e), Section 8.13(c) or Section 9.13. 
  

 27 

 (b) Scheduled and Interim Redeterminations. The Borrowing Base shall be redetermined semi-annually
in accordance with this Section 2.07 (a “Scheduled Redetermination”), and, subject to Section 2.07(d), such redetermined Borrowing Base shall become effective and applicable to the Borrower, the Agents, the Issuing Bank
and the Lenders on May 1st and November 1st of each year, commencing May 1, 2009. In addition, the Borrower may, by notifying the Administrative Agent thereof, and the Administrative Agent may, at the direction of the Majority
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 certificate required to be delivered by the Borrower to the Administrative Agent, in the case of a Scheduled Redetermination, pursuant to Section 8.12(a) and (c), and, in the case of an Interim
Redetermination, pursuant to Section 8.12(b) and (c), 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 good faith, propose a new Borrowing Base (the “Proposed Borrowing Base”) based upon such information and such other information (including, without limitation, the status of title
information with respect to the Oil and Gas Properties as described in the Engineering Reports and the existence of any other Debt) as the Administrative Agent deems appropriate and consistent with its normal oil and gas lending criteria as it
exists at the particular time. In no event shall the Proposed Borrowing Base exceed the Aggregate Maximum Credit Amounts. 
 (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 April 15th and October 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 the Borrower and has had a reasonable opportunity to determine the Proposed Borrowing Base in accordance with Section 2.07(c)(i); and 
  

 28 

 (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 the Required Lenders 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 Majority Lenders 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, the Required Lenders, in the case of a Proposed Borrowing Base that would increase the
Borrowing Base then in effect, or the Majority 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, the Required or Majority 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 the Majority Lenders for purposes of this Section 2.07 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 the Required Lenders or the Majority 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 Agents, 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 May 1st or November 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 notice; and 
 (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 8.13(c) or Section 9.13, 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. 
  

 29 

 (e) Reduction of Borrowing Base Upon Issuance of Permitted Senior Notes. Notwithstanding anything
to the contrary contained herein, upon the issuance of any Senior Notes in accordance with Section 9.02(i), the Borrowing Base then in effect shall be reduced by an amount equal to the product of 0.25 multiplied by the stated principal amount
of such Senior Notes (without regard to any initial issue discount), and the Borrowing Base as so reduced shall become the new Borrowing Base immediately upon the date of such issuance, effective and applicable to the Borrower, the Agents, the
Issuing Bank and the Lenders on such date until the next redetermination or modification thereof hereunder. 
 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. 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 three (3) 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; 
 (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). 
  

 30 

 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. By 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 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, 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 equal to or
greater 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 LC Disbursement be financed with an ABR

  

 31 

 
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 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 substantially 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 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 

  

 32 

 
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 reasonable discretion, either accept and make payment upon such documents without responsibility for further investigation, 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) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among the Borrower, the Administrative
Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank. At the time any such replacement shall become effective, the Borrower shall pay all
unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 3.05(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the
Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such
successor and all previous Issuing Banks, as the context shall require. After the replacement of the Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of the
Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit. 
 (j) 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(j), 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 

  

 33 

 
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) or Section 10.01(i). 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 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(j) 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. Interest or profits, if any, on such deposit 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. 
  

 34 

 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. 
 (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, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower or any Guarantor hereunder or under any other Loan Document
is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to two percent (2%) plus the rate applicable to ABR Loans as
provided in Section 3.02(a), but in no event to exceed the Highest Lawful Rate. 
 (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; 
  

 35 

 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 as an ABR Borrowing. 
 Section 3.04 Prepayments. 
 (a)
Optional Prepayments. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with Section 3.04(b). 
 (b) Notice and Terms of Optional Prepayment. The Borrower shall notify the Administrative Agent by telephone and/or fax (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, on 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 exceeds 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, as a result of an LC Exposure, any excess remains after prepaying all of the
Borrowings 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). 
 (ii) Upon any redetermination of or adjustment to the amount of the Borrowing Base in accordance with Section 2.07(c) or
Section 8.13(c), if the total Revolving Credit Exposures exceeds the redetermined or adjusted Borrowing Base, then the Borrower shall (A) prepay the Borrowings in an aggregate principal amount equal to such excess, and (B) if, as a
result of an LC Exposure, any excess remains after prepaying all of the Borrowings 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 within forty-five (45) days following its receipt of the New Borrowing Base Notice in accordance with Section 2.07(d) or the date the adjustment occurs;
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. 
  

 36 

 (iii) Upon any adjustments to the Borrowing Base pursuant to Section 2.07(e) or
Section 9.13, 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, as a result of an LC
Exposure, any excess remains after prepaying all of the Borrowings 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 disposition or the incurrence of such Senior Notes. 
 (iv) 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 thereto and ending with the Eurodollar Borrowing with the most number of days remaining in the Interest Period applicable thereto. 
 (v) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied ratably to the Loans included in the prepaid
Borrowings. Prepayments pursuant to this Section 3.04(c) 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 applicable Commitment Fee Rate on the average daily amount of the unused amount of the
Commitment of such Lender 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 0.125% per 

  

 37 

 
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 demand. Any other fees payable to the Issuing Bank pursuant to this Section 3.05(b) 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 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 separately agreed upon between the Borrower and the Administrative Agent.

 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 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, but shall be considered received on the date paid for purposes of Section 10.01. 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. 
  

 38 

 (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) 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 restored 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 Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.05(b), Section 2.08(d), Section 2.08(e) or
Section 4.02 then the Administrative Agent may, in its discretion 

  

 39 

 
(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. 
 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 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 
 Section 5.01 Increased Costs. 
 (a) Eurodollar Changes in Law. If any Change in Law 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 

  

 40 

 
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 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 30 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 180 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 180-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, or (d) the assignment of any
Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 5.04(b), 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. 
  

 41 

 (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 for any Indemnified Taxes or Other Taxes; provided that if the Borrower or any Guarantor shall be required to deduct 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 (including deductions applicable to additional sums payable under this Section 5.03), the Administrative
Agent, Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower or such Guarantor shall make such deductions 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 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) Foreign
Lenders. Any Foreign Lender 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 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. 
 (f) Tax
Refunds. If the Administrative Agent or a Lender determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower 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 under this Section 5.03 

  

 42 

 
with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender 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, agrees to repay the amount paid over to the
Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender 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 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. The agreements in this Section 5.03(f) shall survive the termination of this Agreement and the payment of the Loans and the other amounts payable hereunder. 
 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 the Borrower is required to pay any additional amount to any Lender or any Governmental
Authority for the account of any 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 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 the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, or any Lender defaults in its obligation to fund Loans hereunder,
then the Borrower may, at its sole expense, 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. 
  

 43 

 (c) Replacement for Borrowing Base Increase. If (i) an existing Lender does not approve a
proposed Borrowing Base increase and (ii) the Required Lenders have approved such proposed Borrowing Base increase, then the Borrower may, at its sole expense, within 3 Business Days after the Borrower receives the New Borrowing Base Notice
with respect to such increase, at the discretion of such existing Lender either: 
 (A) cause such existing Lender to assign
and delegate, without recourse, all its interests, rights and obligations under this Agreement to one or more assignees proposed by the Borrower that shall assume such obligations (which assignees may be another Lender, if a Lender accepts such
assignment), provided that such existing 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(s) (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts), or 
 (B) cause such existing Lender to reduce its Maximum Credit Amount based upon a new Applicable Percentage for such existing Lender that is
calculated by dividing such existing Lender’s then outstanding Revolving Credit Exposure by the increased Borrowing Base and assigning the balance of its Maximum Credit Amount to an assignee or assignees proposed by the Borrower that shall
assume such amount of the assigning Lender’s Maximum Credit Amount (which assignee may be another Lender, if a Lender accepts such assignment). 
 Any such replacement of an existing Lender or partial assignment of an existing Lender’s Maximum Credit Amount shall be in accordance with and subject to the restrictions contained in Section 12.04(b).

 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

  

 47 

 
by any class of directors of the Borrower, 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 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, 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, 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 income, stockholders equity and cash flows (i) as of and for the fiscal year ended December 31, 2007,
reported on by Deloitte & Touche LLP, independent public accountants, and (ii) as of and for the fiscal quarter and the portion of the fiscal year ended June 30, 2008. 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 dates and for such periods in accordance with GAAP, subject to year-end audit adjustments and the absence of
footnotes in the case of the unaudited quarterly financial statements. 
 (b) Since December 31, 2007, (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 (other
than the Gas Balancing Obligations and the Swap Agreements listed on Schedule 7.20) which are not referred to or reflected or provided for in the Financial Statements.

 (g) neither the Borrower nor any Restricted Subsidiary has any known contingent liability or Remedial Work in connection with any release
or threatened release of any oil, hazardous substance, solid waste or oil and gas waste into the environment.

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 pursuant to

 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 other 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 

  

 51 

 
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. No statements or conclusions exist in any
Reserve Report which are based upon or include misleading information or which fail to take into account material information regarding the matters reported therein to the extent such misstatement, misleading information or failure could reasonably
be expected to have a Material Adverse Effect. 
 Section 7.12 Insurance. The Borrower has, and has caused all 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 (other than Capital Leases creating Liens permitted by Section 9.03(c), but then only on the Property subject of such Capital Lease), or subject to any order, judgment, writ or decree, which either restricts or purports to restrict
its ability to grant Liens to the Administrative Agent and the Lenders on or in respect of their Properties to secure the Indebtedness and the Loan Documents. 
 Section 7.14 Subsidiaries. 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 Foreign 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 Delaware; the
name of the Borrower as listed in the public records of its jurisdiction of organization is Petrohawk Energy Corporation; and the organizational identification number of the Borrower in its jurisdiction of organization is 3828463 (or, in each case,
as set forth in a notice delivered to the Administrative Agent pursuant to Section 8.01(m) 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(m) and Section 12.01(c)). 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 7.14 (or as set forth in a notice delivered pursuant to

 Section 7.16 Properties; Titles, Etc. 
  

 52 

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

  

 53 

 
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 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 Gas Imbalances, Prepayments. Except as set forth on Schedule 7.18 or on the most recent certificate delivered pursuant to
Section 8.12(c), on a net basis there are no gas imbalances, take or pay or other prepayments which would require the Borrower or any of its Restricted Subsidiaries to deliver Hydrocarbons produced from the Oil and Gas Properties at some future
time without then or thereafter receiving full payment therefor exceeding a volume equal to 1% of the total proved reserves (on an mcf equivalent basis) set forth in the most recently delivered Reserve Report in the aggregate. 
 Section 7.19 Marketing of Production. Except for contracts listed and in effect on the date hereof on Schedule 7.19, 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 Restricted Subsidiaries are receiving a price for all
production sold thereunder which is computed substantially in accordance with the terms of the relevant contract and are not having deliveries curtailed substantially below the subject Property’s delivery capacity), no material agreements exist
which are not cancelable on 60 days notice or less without penalty or detriment for the sale of production from the Borrower’s or its Restricted Subsidiaries’ Hydrocarbons (including, without limitation, calls on or other rights to
purchase production, whether or not the same are currently being exercised) that (a) pertain to the sale of production at a fixed price and (b) have a maturity or expiry date of longer than six (6) months from the date hereof.

 Section 7.20 Swap Agreements. Schedule 7.20, as of the date hereof, and after the date hereof, each report required to be
delivered by the Borrower pursuant to Section 8.01(e), sets forth, a true and complete list of all Swap Agreements of the Borrower and each Restricted Subsidiary, the material terms thereof (including the type, term, effective date, termination
date and notional amounts or volumes), the net mark to market value thereof, all credit support agreements relating thereto (including any margin required or supplied) and the counterparty to each such agreement. 
  

 54 

 Section 7.21 Use of Loans and Letters of Credit. The proceeds of the Loans and the Letters of
Credit shall be used to provide working capital for exploration and production operations, to provide funding for general corporate purposes, including the issuance of letters of credit. The Borrower and its Subsidiaries are not engaged principally,
or as one of its or their important activities, in the business of extending credit for the purpose, whether immediate, incidental or ultimate, of buying or carrying margin stock (within the meaning of Regulation T, U or X of the Board). No part of
the proceeds of any Loan or Letter of Credit will be used for any purpose which violates the provisions of Regulations T, U or X of the Board. 
 Section 7.22 Solvency. After giving effect to the transactions contemplated hereby, (a) the aggregate assets (after giving effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any
similar arrangement), at a fair valuation, of the Borrower and the Guarantors, taken as a whole, will exceed the aggregate Debt of the Borrower and the Guarantors on a consolidated basis, as the Debt becomes absolute and matures, (b) each of
the Borrower and the Guarantors will not have incurred or intended to incur, and will not believe that it will incur, Debt beyond its ability to pay such Debt (after taking into account the timing and amounts of cash to be received by each of the
Borrower and the Guarantors and the amounts to be payable on or in respect of its liabilities, and giving effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any similar arrangement) as such Debt becomes
absolute and matures and (c) each of the Borrower and the Guarantors will not have (and will have no reason to believe that it will have thereafter) unreasonably small capital for the conduct of its business.

 Section 8.07 Insurance. The Borrower will, and will cause each Restricted Subsidiary to, maintain, with
financially sound and reputable insurance companies, insurance in such amounts and against such risks as are customarily maintained by companies engaged in the same or similar businesses operating in the same or similar locations. The loss payable

under the supervision of the chief engineer of the Borrower who shall certify such Reserve Report to be true and accurate in all material respects and to have been prepared in accordance with the procedures used in the immediately preceding

 62 

 
requested by the Administrative Agent or the Borrower pursuant to Section 2.07(b), the Borrower shall provide such Reserve Report with an “as
of” date as required by the Administrative Agent as soon as possible, but in any event no later than thirty (30) days following the receipt of such request. 
 (c) With the delivery of each Reserve Report, the Borrower shall provide to the Administrative Agent and the Lenders a certificate from a Responsible Officer 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 in all material respects, (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 gas imbalances,
take or pay or other prepayments in excess of the volume specified in Section 7.18 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 delivered Reserve Report which the Borrower could reasonably be expected to have been obligated to list on Schedule 7.20 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 that the Borrower is in compliance with
Section 8.14(a). 
 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, reasonably satisfactory title information on at least 75% of the total value of the Oil and Gas Properties evaluated by such
Reserve Report. 
 (b) If the Borrower has provided title information for additional Properties under Section 8.13(a), the Borrower
shall, within 90 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, reasonably satisfactory title information on at least 75% of the total value of the Oil and Gas Properties evaluated by such Reserve Report. 
  

 63 

 (c) If the Borrower is unable to cure any title defect requested by the Administrative Agent or the
Lenders to be cured within the 90-day period or the Borrower does not comply with the requirements to provide acceptable title information covering 75% of the Oil and Gas Properties evaluated in the most recent Reserve Report, such default shall not
be a Default, but instead the Administrative Agent and/or the Majority 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 Majority Lenders are not satisfied with title to any Mortgaged Property after the 90-day period has elapsed,
such unacceptable Mortgaged Property shall not count towards the 75% 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 Majority Lenders to cause the Borrower to be in compliance with the requirement to provide acceptable title information on 75% of the value of the Oil and Gas Properties. 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 total value of the Oil and Gas Properties evaluated in the most recently completed Reserve Report 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 certificate required under Section 8.12(c), to the Administrative Agent as security for the Indebtedness a first-priority Lien interest (subject only to Excepted Liens of the type
described in clauses (a) to (d) and (f) of the definition thereof, 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 total value. 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 incurs or guarantees any Debt, the Borrower shall promptly cause such Restricted Subsidiary to guarantee the Indebtedness pursuant to the Guaranty 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 Guaranty Agreement executed by such Subsidiary, (B) pledge all of the Equity Interests of such 

  

 64 

 
new Subsidiary (including, without limitation, delivery of original stock certificates evidencing the Equity Interests of such Subsidiary, together with an

by the Administrative Agent. 
 (c) In the event that the Borrower or any Domestic Subsidiary becomes the owner of a Foreign Subsidiary which
has total assets in excess of $10,000,000, then the Borrower shall promptly, or shall cause such Domestic Subsidiary to promptly, guarantee the Indebtedness pursuant to the Guaranty Agreement. In connection with any such guaranty, the Borrower
shall, or shall cause such Domestic Subsidiary to, (i) execute and deliver a supplement to the Guaranty Agreement, (ii) pledge 65% of all the Equity Interests of such Foreign Subsidiary (including, without limitation, delivery of original
stock certificates evidencing such Equity Interests of such Foreign Subsidiary, together with appropriate stock powers for each certificate duly executed in blank by the registered owner thereof) and (iii) execute and deliver such other
additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent. 
 Section 8.15 ERISA Compliance. The Borrower will promptly furnish and will cause the Subsidiaries and any ERISA Affiliate to promptly furnish to the Administrative Agent (i) promptly after the filing thereof with the United
States Secretary of Labor or the Internal Revenue Service, copies of each annual and other report with respect to each Plan or any trust created thereunder, and (ii) immediately upon becoming aware of the occurrence of any “prohibited
transaction,” as described in section 406 of ERISA or in section 4975 of the Code, in connection with any Plan or any trust created thereunder, a written notice signed by the President or the principal Financial Officer, the Subsidiary or the
ERISA Affiliate, as the case may be, specifying the nature thereof, what action the Borrower, the Subsidiary or the ERISA Affiliate is taking or proposes to take with respect thereto, and, when known, any action taken or proposed by the Internal
Revenue Service or the Department of Labor with respect thereto. 
 Section 8.16 Swap Agreements. The Borrower shall or shall
cause one or more of its Restricted Subsidiaries (which is a Guarantor) to maintain the hedged position established by the Swap Agreements included in Schedule 7.20 during the period from the Effective Date until the next redetermination of the
Borrowing Base and shall neither assign, terminate or unwind any such Swap Agreements nor sell any Swap Agreements if the effect of such action (when taken together with any other Swap Agreements executed contemporaneously with the taking of such
action) would have the effect of canceling its positions under such Swap Agreements required hereby. 
 Section 8.17 Unrestricted
Subsidiaries. The Borrower: 
 (a) will cause the management, business and affairs of each of the Borrower and its Restricted
Subsidiaries to be conducted in such a manner (including, without limitation, by keeping separate books of account, furnishing separate financial statements of Unrestricted Subsidiaries to creditors and potential creditors thereof and by not
permitting Properties of the Borrower and its respective Restricted Subsidiaries to be commingled) so that each Unrestricted Subsidiary that is a corporation will be treated as a corporate entity separate and distinct from Borrower and the
Restricted Subsidiaries. 
  

 65 

 (b) will not, and will not permit any of the Restricted Subsidiaries to, incur, assume, guarantee or be
or become liable for any Debt of any of the Unrestricted Subsidiaries. 
 (c) will not permit any Unrestricted Subsidiary to hold any Equity
Interest in, or any Debt of, the Borrower or any Restricted Subsidiary. 
 Section 8.18 Marketing Activities. The Borrower will
not, and will not permit any of its Restricted Subsidiaries to, engage in marketing activities for any Hydrocarbons or enter into any contracts related thereto other than (i) contracts for the sale of Hydrocarbons scheduled or reasonably
estimated to be produced from their proved Oil and Gas Properties during the period of such contract, (ii) contracts for the sale of Hydrocarbons scheduled or reasonably estimated to be produced from proved Oil and Gas Properties of third
parties during the period of such contract associated with the Oil and Gas Properties of the Borrower and its Restricted Subsidiaries that the Borrower or one of its Restricted Subsidiaries has the right to market pursuant to joint operating
agreements, unitization agreements or other similar contracts that are usual and customary in the oil and gas business and (iii) other contracts for the purchase and/or sale of Hydrocarbons of third parties (A) which have generally
offsetting provisions (i.e. corresponding pricing mechanics, delivery dates and points and volumes) such that no “position” is taken and (B) for which appropriate credit support has been taken to alleviate the material credit risks of
the counterparty thereto.

 (b) The Borrower may designate by written notification thereof to the Administrative Agent, any Restricted Subsidiary, including a newly formed or newly acquired Subsidiary, as an Unrestricted Subsidiary if (i) prior, and after giving
effect, to such designation, neither a Default nor a Borrowing Base deficiency would exist and (ii) such designation is deemed to be an Investment in an Unrestricted Subsidiary in an amount equal to the fair market value as of the date of such
designation of the Borrower’s direct and indirect ownership interest in such Subsidiary and such Investment would be permitted to be made at the time of such designation under Section 9.05(l). Except as provided in this

then the Borrowing Base shall be reduced, effective immediately upon such sale or disposition, by an amount equal to the value, if any, assigned such Property in the most recently delivered Reserve Report and (iv) if any such sale or other

Debt for borrowed money which bears interest at a fixed rate and (ii) 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

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. 
  

 77 

 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, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except as provided in Section 11.03, and (c) except as

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

 Section 11.03 Action by Administrative Agent. The Administrative Agent shall not have any duty to take any discretionary action or exercise
any discretionary powers, except discretionary rights and powers expressly contemplated hereby 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 

  

 78 

 
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 any Co-Syndication Agents nor any Co-Documentation Agent shall have any obligation to perform any act in respect thereof. No Agent shall 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 no
Agent shall 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 Agents may deem and treat the payee of the Note, if any, 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.

and the Borrower, and any 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, with the consent of the Borrower, which consent shall not be
unreasonably withheld or delayed, to appoint a successor. If no successor shall have been so appointed 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, 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, 

  

 79 

 
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. 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 Arranger 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. 
 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 
  

 80 

 (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 Liens. Each Lender and the Issuing Bank hereby authorizes the
Administrative Agent to release 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
sale or other disposition is permitted by the terms of Section 9.13 or is otherwise authorized by the terms of the Loan Documents. 
 Section 11.11 The Arranger, the Co-Syndication Agents and the Co-Documentation Agents. The Arranger, the Co-Syndication Agents and the Co-Documentation Agents 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.

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

  

 82 

 
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 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 or by the Borrower and the Administrative Agent with the consent of the Majority Lenders; provided that no such agreement shall (i) increase the Maximum Credit Amount or Commitment of any Lender without the
written consent of such Lender, (ii) increase the Borrowing Base without the written consent of the Required Lenders, decrease or maintain the Borrowing Base without the consent of the Majority Lenders, or modify Section 2.07 without the
consent of each Lender, (iii) reduce the principal amount of the 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 the 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(c), Section 6.01,
Section 8.14, Section 10.02(c) or Section 12.14 or change the definition of the terms “Domestic Subsidiary”, “Foreign Subsidiary”, “Material Domestic Subsidiary” or “Subsidiary”, without the
written consent of each Lender, (vii) release any Guarantor (except as set forth in the Guaranty Agreement), release a substantial portion of the collateral (other than as provided in Section 11.10), or reduce the percentage set forth in
Section 8.14(a) to less than 80%, without the written consent of each Lender, or (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 or the Issuing Bank hereunder or under any other Loan Document without the
prior written consent of the Administrative Agent or the Issuing Bank, as the case may be. 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 and its Affiliates, including, without limitation, the reasonable fees, charges and disbursements of counsel and other outside consultants for the Administrative Agent, the reasonable travel, photocopy,

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

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 ISSUING BANK, THE ARRANGER AND EACH LENDER, AND EACH RELATED PARTY OF ANY OF THE FOREGOING PERSONS (EACH
SUCH PERSON BEING CALLED AN “INDEMNITEE”) AGAINST, AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES AND RELATED EXPENSES, INCLUDING THE REASONABLE FEES, CHARGES AND DISBURSEMENTS OF ANY
COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF (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 ANY RESTRICTED SUBSIDIARY TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING THIS AGREEMENT, OR WITH ANY GOVERNMENTAL REQUIREMENT, (iii) ANY INACCURACY OF ANY REPRESENTATION OR ANY BREACH
OF ANY WARRANTY OR COVENANT OF THE BORROWER OR ANY GUARANTOR SET FORTH IN ANY OF THE LOAN DOCUMENTS OR ANY INSTRUMENTS, DOCUMENTS OR CERTIFICATIONS DELIVERED IN CONNECTION THEREWITH, (iv) ANY LOAN OR LETTER OF CREDIT OR THE USE OF THE PROCEEDS

OF CREDIT, OR (B) THE PAYMENT OF A DRAWING UNDER ANY LETTER OF CREDIT 

  

 84

OF THE LOAN DOCUMENTS, (vi) THE OPERATIONS OF THE BUSINESS OF THE BORROWER AND ITS SUBSIDIARIES BY THE BORROWER AND ITS SUBSIDIARIES, (vii) ANY ASSERTION THAT THE LENDERS WERE NOT ENTITLED TO RECEIVE THE PROCEEDS RECEIVED PURSUANT TO THE

LIABILITY, (xi) THE PRESENCE, USE, RELEASE, STORAGE, TREATMENT, DISPOSAL, GENERATION, THREATENED RELEASE, TRANSPORT, ARRANGEMENT FOR TRANSPORT OR ARRANGEMENT FOR DISPOSAL OF OIL, OIL AND GAS WASTES, SOLID WASTES OR HAZARDOUS SUBSTANCES 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, (xii) ANY
ENVIRONMENTAL LIABILITY RELATED IN ANY WAY TO THE BORROWER OR ANY OF ITS SUBSIDIARIES, OR (xiii) ANY OTHER ENVIRONMENTAL, HEALTH OR SAFETY CONDITION IN CONNECTION WITH THE LOAN DOCUMENTS, OR (xiv) ANY ACTUAL OR PROSPECTIVE 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 AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILFUL MISCONDUCT OF SUCH INDEMNITEE. 
  

 85 

 (c) To the extent that the Borrower fails to pay any amount required to be paid by it to any Agent or the
Issuing Bank under Section 12.03(a) or (b), each Lender severally agrees to pay to such Agent 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 or the Issuing Bank in
its capacity as such. 
 (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 not later than 5 days 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 for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, 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. 
  

 86 

 (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 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 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. 
  

 87 

 (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 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. 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.

  

 88 

 (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 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, 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 

  

 89 

 
FINAL AGREEMENT AMONG THE PARTIES HERETO AND THERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT 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. 
 Section 12.09 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS. 
 (a) THIS AGREEMENT AND THE NOTES, IF ANY, SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS EXCEPT TO THE EXTENT
THAT UNITED STATES FEDERAL LAW PERMITS ANY LENDER TO CONTRACT FOR, CHARGE, RECEIVE, RESERVE OR TAKE INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE STATE WHERE SUCH LENDER IS LOCATED. CHAPTER 346 OF THE TEXAS FINANCE CODE (WHICH REGULATES CERTAIN
REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) SHALL NOT APPLY TO THIS AGREEMENT, THE LOANS OR THE NOTES, IF ANY. 
  

 90

 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, (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 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 Texas 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 Loans, 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 Loans 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 Loans 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 

  

 92 

 
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, 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 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. To the extent that Chapter 303 of the Texas Finance Code is relevant
for the purpose of determining the Highest Lawful Rate applicable to a Lender, such Lender elects to determine the applicable rate ceiling under such Chapter by the weekly ceiling from time to time in effect. Chapter 346 of the Texas Finance Code
does not apply to the Borrower’s obligations hereunder. 
 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.” 
  

 93 

 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. 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.

the same meanings assigned to them in the Credit Agreement. 
 In connection with the opinions set forth herein, we have examined originals,
or copies certified or otherwise identified to our satisfaction, of the following documents (items (A) through (D) being referred to as the “Loan Documents”): 
  

	 	(A)	the Credit Agreement; 

  

 Exhibit E - 1 

	 	(B)	the Third Amended and Restated Guarantee and Collateral Agreement dated of even date with the Credit Agreement executed by the Obligors in favor of the Administrative Agent for the

(collectively, the “Mortgages”); and 

  

	 	(D)	the Notes. 

 In rendering the opinions set forth herein,
we have relied upon certificates of officers and general partners of the Obligors or certificates of public officials and such other documents, records and information as we have deemed necessary or appropriate. We have assumed that all signatures
are genuine; that all documents submitted to us as originals are authentic; that all documents submitted to us as copies conform to the originals; and that the facts stated in all such documents are true and correct. We have also assumed the Loan
Documents constitute valid, binding and enforceable obligations of each party thereto (other than Obligors). In addition, we have relied on the completeness and accuracy of the books and record, including the stock ledger of each Obligor, without
independent investigation, as to the opinions regarding ownership and no liens. In rendering this opinion, we have not made any independent investigation as to accuracy or completeness of any facts or representations, warranties, data or other
information, whether written or oral, that may have been made by or on behalf of the parties, except as specifically set forth herein. 
 “Applicable Laws” means those laws, rules and regulations of the State of Texas and the State of Oklahoma, and the federal laws, rules and regulations of the United States of America, that in our experience are normally
applicable to the Obligors, the Loan Documents or transactions of the type contemplated by the Loan Documents, and, for purposes of our opinions in paragraphs 2, 3 and 4 below, include Delaware General Corporation Law, the Delaware Limited Liability
Company Act, the Delaware Revised Uniform Limited Partnership Act and the Louisiana Business Corporation Law. In addition, the term “Applicable Laws” does not include: 
 (i) Any state or federal laws, rules or regulations relating to: (A) pollution or protection of the environment; (B) zoning,
land use, building or construction; (C) occupational safety and health or other similar matters; (D) labor, employee rights 

  

 Exhibit E - 2 

 
and benefits, including without limitation the Employee Retirement Income Security Act of 1974, as amended; (E) the regulation of utilities;
(F) antitrust and trade regulation; (G) tax; (H) securities, including without limitation federal and state securities laws, rules or regulations, and the Investment Company Act of 1940, as amended; (I) corrupt practices,
including without limitation the Foreign Corrupt Practices Act of 1977; and (J) copyrights, patents, service marks and trademarks. 
 (ii) Any laws, rules or regulations of any county, municipality or similar political subdivision or any agency or instrumentality thereof. 
 (iii) Any laws, rules or regulations that are applicable to the Obligors, the Loan Documents or such transactions solely because such
laws, rules or regulations are part of a regulatory regime applicable to any party to any of the Loan Documents or any of its affiliates because of the specific assets or business of such party or such affiliate. 
 (iv) The laws of the State of Delaware, except to the extent based on our review of the Delaware General Corporation Law, the Delaware
Limited Liability Company Act and the Delaware Revised Uniform Limited Partnership Act, without consideration of any judicial or administrative interpretations thereof. 
 (v) The laws of the State of Louisiana, except to the extent based on our review of the Louisiana Business Corporation Law, without
consideration of any judicial or administrative interpretations thereof. 
 (vi) The laws of the State of Idaho except to the
extent based on our review of the Idaho Limited Liability Company Act, without consideration of any judicial or administrative interpretations thereof. 
 Based upon the foregoing, and subject to the qualifications set forth herein, it is our opinion that:

 Exhibit E - 4 

 The foregoing opinions with respect to good standing are given solely on the basis of certificates of
appropriate state agencies of the identified states, and such opinions are limited to the meaning ascribed to such certificates by each applicable state agency. 
 2. Each of the Obligors has the corporate, limited liability company or partnership (as applicable) power and authority to execute, deliver and perform its obligations under each of the Loan Documents to which it is a
party. The Borrower has taken all corporate action and each Guarantor has taken all necessary corporate, limited liability company or partnership (as applicable) action to authorize the execution and delivery of, and performance of its obligations
under, each of the Loan Documents to which it is a party. Such execution, delivery and performance of its obligations under the Loan Documents to which it is a party will not (i) result in a violation of the Borrower’s or any
Guarantor’s formation document, By-laws, Limited Partnership Agreement, Operating Agreement or Limited Liability Company Agreement (as applicable), or any Applicable Law, (ii) result in a violation of or constitute a breach or default
under any material agreement or instrument relating to the borrowing of money or judicial or regulatory order binding upon it, or (iii) result in the creation or imposition of any Lien on any of its properties pursuant to any such material
agreement or instrument or judicial or regulatory order. Each of the Loan Documents to which an Obligor is a party has been duly authorized, executed and delivered by such Obligor. 
 3. Each of the Loan Documents constitutes the legal, valid and binding obligation of each Obligor party thereto, enforceable against it in accordance
with its terms, except that enforcement may be subject to any applicable bankruptcy, insolvency, or similar debtor relief laws now or hereafter in effect and relating to or affecting the enforcement of creditors’ rights generally, and subject,
as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity). The enforceability and binding
nature of each of the Obligors’ obligations under the Loan Documents are subject to the qualification that certain provisions of the Loan Documents are or may be unenforceable in whole or in part (but the inclusion of such provisions does not
affect the validity of the instruments, and each instrument contains adequate provisions for the practical realization of the material benefits afforded thereby). Further, we express no opinion as to the enforceability of provisions in the Loan
Documents (i) purporting to waive any rights of any Obligor, (ii) purporting to grant powers of attorney or authority to execute documents or to act by power of attorney on behalf of any Obligor, (iii) purporting to restrict access to
legal or equitable remedies (including, without limitation, proper jurisdiction and venue), (iv) purporting to grant to the Administrative Agent or the Lenders a right of set-off against any accounts belonging to a third party or otherwise held
by any Obligor in a fiduciary or like capacity, (v) purporting to release, exculpate or exempt a party from, or require the indemnification of a party for, liability for its own action or inaction, to the extent that the same are inconsistent
with public policy, (vi) purporting to establish evidentiary standards for suits or proceedings to enforce the Loan Documents, (vii) that relate to subrogation rights, delay or omission of enforcement of rights and remedies, or
(viii) that decisions by a party are conclusive. In addition, we express no opinion with respect to the enforceability of any provision of the Loan Documents prohibiting or purporting not to give effect to oral amendments or oral waivers to
Loan Documents or limiting the effect of a course of dealing between the parties thereto. 
  

 Exhibit E - 5 

 4. No authorization, consent, approval, license or exemption of, or filing or registration with, any
Governmental Authority of the United States or any Governmental Authority of the State of Delaware, Oklahoma, Louisiana, or Texas in connection with any Applicable Law is necessary for either (i) the due execution and delivery by each Obligor
of the Loan Documents to which it is a party, (ii) the borrowing of Loans and obtaining of Letters of Credit by the Borrower or (iii) payment by the Obligors of the Loans or any other amounts payable under the Loan Documents. 

5. There are, to the best of our knowledge, no actions, suits or proceedings pending or threatened against any Obligor or its property which involves
the possibility of any judgment or liability against such Obligor which could reasonably be expected to have a Material Adverse Effect. 
 6.
None of the Obligors is subject to regulation under the Investment Company Act of 1940, as amended, or the Public Utility Holding Company act of 1935, as amended. 
 Our opinion as to any factual matter in connection with this opinion is limited to the current actual knowledge of the lawyers in our firm who have participated in the negotiation and preparation of this opinion, and
does not include constructive inquiry or imputed knowledge. We advise you that no special investigation of the relevant facts or circumstances has been made. In that connection, we have made no review of the files of the Obligors whether in the
possession of the Obligors or the possession of any other party. In addition, we have made no investigation or review of any agreements, instruments, judgments, decrees, franchises, permits, rules or other regulations or decrees by which the
Obligors may be bound and have made no independent search through the records of any judicial authority or governmental agency or as to the existence of any actions, suits, investigations or proceedings, if any, pending or threatened against the
Obligors. 
 The opinions rendered herein are for the sole benefit of, and may only be relied upon by the Lenders and the Administrative
Agent, together with any successors or permitted assigns, and the opinions herein expressed are not to be used, disclosed, quoted, filed with a Governmental Authority or otherwise referred to in connection with any transaction other than those
contemplated by the Loan Documents without our prior written consent. We assume no obligation to supplement this opinion if any applicable laws change after the date of this opinion, or if we become aware of any facts that might change the opinions
expressed above after the date of this opinion. We have not been asked to, and we do not, render any opinion as to any matter except as specifically set forth herein. 
  

	
	Very truly yours,

reliance on, or in contemplation of the benefits of, the validity, enforceability, collectability or value of any of the Collateral for the Obligations; (E) any failure of the Administrative Agent or any other Secured Party to marshal assets in

right or remedy with respect thereto; or notice of any other matters relating thereto; the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance
upon the guarantee contained in Article II and the collateral security provided herein and no notice of creation of the Obligations or any extension of credit already or hereafter contracted by or extended to the Borrower need be given to any
Grantor; and all dealings between the Borrower and any of the Grantors, on the one hand, and the Administrative Agent and the other Secured Parties, on the

 (c) When making any demand hereunder or otherwise pursuing its
rights and remedies hereunder against any Grantor, the Administrative Agent or any other Secured Party may, but shall be under no obligation to, join or make a similar demand on or otherwise pursue or exhaust such rights and remedies as it may have

or any release of the Borrower, any Grantor or any other Person or any such collateral security, guarantee or right of offset, shall not relieve any Grantor of any obligation or liability hereunder, and shall not impair or affect the rights and

Grantor hereunder or any set-off or application of funds of any Grantor by the Administrative Agent or any other Secured Party, no Grantor shall be entitled to be subrogated to any of the rights of the Administrative Agent or any other Secured Party
against the Borrower or any other Grantor or any collateral security or guarantee or right of offset held by the Administrative Agent or any other Secured Party for the payment of the Obligations, nor shall any Grantor seek or be entitled to seek

all such rights of subrogation, reimbursement, indemnity and contribution. Each Grantor further agrees that to the extent that such waiver and release set forth herein is found by a court of competent jurisdiction to be void or voidable for any
reason, any rights of subrogation, reimbursement, indemnity and contribution such Grantor may have against the Borrower, any other Grantor or against any collateral or security or guarantee or right of offset held by the Administrative Agent or any
other Secured Party shall be junior and subordinate to any rights the Administrative Agent and the other Secured Parties may have against the Borrower and such Grantor and to all right, title and interest the Administrative Agent and the other
Secured Parties may have in any collateral or security or guarantee or right of offset. The Administrative Agent, for the benefit of the Secured Parties, may use, sell or dispose of any item of Collateral or security as it sees fit without regard to
any subrogation rights any Grantor may have, and upon any disposition or sale, any rights of subrogation any Grantor may have shall terminate.

 Section 5.04 Title; No Other Liens. Except for the security interest granted to the Administrative Agent for the ratable benefit of the Secured Parties pursuant to this Agreement and Excepted Liens, such Grantor is the legal and
beneficial owner of its respective items of the Collateral free and clear of any and all Liens. No financing statement or other public notice with respect to all or any part of the Collateral is on file or of record in any public office, except such

the filings and other actions specified on Schedule 3 (which, in the case of all filings and other documents referred to on said Schedule, have been delivered to the Administrative Agent in completed and duly executed form) will constitute valid
perfected security interests in all of the Collateral in favor of the Administrative Agent, for the 
  

 - 9 - 

 
ratable benefit of the Secured Parties, as collateral security for such Grantor’s obligations, enforceable in accordance with the terms hereof against
all creditors of such Grantor and any Persons purporting to purchase any Collateral from such Grantor and (b) are prior to all other Liens on the Collateral in existence on the date hereof except for Excepted Liens which have priority over the
Liens on the Collateral by operation of law.

validly issued and, in the case of shares of stock of a corporation, are fully paid and nonassessable; and such Grantor is the record and beneficial owner of, and has good title to, the Pledged Securities pledged by it hereunder, free of any and all
Liens except Excepted Liens or options, warrants, puts, calls or other rights of any other Person, and restrictions or options in favor of, or claims of, any other Person, except the security interest created by this Agreement. The pledged LLC
interests and the pledged partnership interests do not, by their terms, provide that they are securities to be governed by Article 8 of the Code – Investment Securities. 
 Section 5.09 Goods. No portion of the Collateral constituting Goods is in the possession of a bailee that has issued a negotiable or
non-negotiable document covering such Collateral.

Administrative Agent all Collateral constituting Instruments and Chattel Paper. No Collateral constituting Chattel Paper or Instruments contains any statement therein to the effect that such Collateral has been assigned to an identified party other

writing at any time heretofore or hereafter furnished by such Grantor to the Administrative Agent or any other Secured Party, and all other written information heretofore or hereafter furnished by such Grantor to the Administrative Agent or any

thereof owned by any Grantor. Each Grantor will not permit any Issuer of any of the Pledged Securities to issue any new shares (or other interests) of any class of capital stock or other Equity Interests of such Issuer without the prior written
consent of the Administrative Agent. 
 (f) Each Pledgor shall not agree to any amendment of a partnership agreement, LLC
agreement or other organic document relating to any Pledged Security that in any way adversely affects the perfection of the security interest of the Administrative Agent in the Pledged Securities, including any amendment electing to treat the
membership interest or partnership interest of such Pledgor as a security under Section 8-103 of the Texas UCC. In the event of a foreclosure or a taking of Pledged Securities consisting of partnership interests or LLC interests in lieu of
foreclosure pursuant to any Security Instrument executed in connection with the Credit Agreement, the Administrative Agent or its assignee or transferee, at any of their option, will, without any further action or consent, become a member or partner
upon the exercise of such option by the Administrative Agent, its assignee or transferee, having all of the

rights, powers and privileges of a member or partner with respect to such Equity Interest, including, without limitation, the right to participate in the
management of the business, to vote such Equity Interest and to receive distributions hereunder. 
 Section 6.10 Limitations on
Modifications, Waivers, Extensions of Agreements Giving Rise to Accounts. Such Grantor will not (i) amend, modify, terminate or waive any provision of any Chattel Paper, Instrument or any agreement giving rise to an Account or Payment
Intangible in any manner which could reasonably be expected to materially adversely affect the value of such Chattel Paper, Instrument, Payment Intangible or Account as Collateral, or (ii) fail to exercise promptly and diligently each and every
material right which it may have under any Chattel Paper, Instrument and each agreement giving rise to an Account or Payment Intangible (other than any right of termination). Such Grantor shall deliver to the Administrative Agent a copy of each
material demand, notice or document received by it relating in any way to any Chattel Paper, Instrument or any agreement giving rise to an Account or Payment Intangible. 
 Section 6.11 Analysis of Accounts, Etc. The Administrative Agent shall have the right from time to time to make test verifications of the Accounts, Chattel Paper and Payment Intangibles in any manner and
through any medium that it reasonably considers advisable, and each Grantor, at such Grantor’s sole cost and expense, shall furnish all such assistance and information as the Administrative Agent may reasonably require in connection therewith.
At any time and from time to time, upon the Administrative Agent’s request and at the expense of each Grantor, such Grantor shall furnish to the Administrative Agent reports showing reconciliations, aging and test verifications of, and trial
balances for, the Accounts, Chattel Paper and Payment Intangibles, and all original and other documents evidencing, and relating to, the agreements and transactions which gave rise to the Accounts, Chattel Paper and Payment Intangibles, including,
without limitation, all original orders, invoices and shipping receipts. 
 Section 6.12 Instruments and Tangible Chattel Paper. If
any amount payable under or in connection with any of the Collateral shall be or become evidenced by any Instrument or Tangible Chattel Paper, such Instrument or Tangible Chattel Paper shall be immediately delivered to the Administrative Agent, duly
endorsed in a manner satisfactory to the Administrative Agent, to be held as Collateral pursuant to this Agreement. 
 Section 6.13

and repairs necessary for such purpose.

Commercial Tort Claim that satisfies the requirements of the following sentence, such Grantor shall, within thirty (30) days after such Commercial Tort Claim satisfies such requirements, notify the Administrative Agent and the other Secured
Parties in a writing signed by such Grantor containing a brief description thereof, and granting to the Administrative Agent in such writing (for the benefit of the Secured Parties) a security interest therein and in the Proceeds thereof, all upon
the terms of this Agreement, with such writing to be in form and substance satisfactory to the Administrative Agent and the other Secured Parties. The provisions of the preceding sentence shall apply only to a Commercial Tort Claim that satisfies
the following 

  

 - 15 - 

 
requirements: (i) the monetary value claimed by or payable to the relevant Grantor in connection with such Commercial Tort Claim shall exceed
$4,000,000, and either (ii) (A) such Grantor shall have filed a law suit or counterclaim or otherwise commenced legal proceedings (including, without limitation, arbitration proceedings) against the Person against whom such Commercial Tort
Claim is made, or (B) such Grantor and the Person against whom such Commercial Tort Claim is asserted shall have entered into a settlement agreement with respect to such Commercial Tort Claim. In addition, to the extent that the existence of
any Commercial Tort Claim held or acquired by any Grantor is disclosed by such Grantor in any public filing with the Securities Exchange Commission or any successor thereto or analogous Governmental Authority, or to the extent that the existence of
any such Commercial Tort Claim is disclosed in any press release issued by any Grantor, then, upon the request of the Administrative Agent, the relevant Grantor shall, within thirty (30) days after such request is made, transmit to the

Agreement, and to exercise all voting and corporate rights with respect to the Pledged Securities.

Default shall occur and be continuing, then at any time in the Administrative Agent’s discretion without notice, (i) the Administrative Agent shall have the right to receive any and all cash dividends, payments or other Proceeds paid in
respect of the Pledged Securities and make application thereof to the Obligations in accordance with Section 10.02 of the Credit Agreement, and (ii) any or all of the Pledged Securities shall be registered in the name of the Administrative
Agent or its nominee, and the Administrative Agent or its nominee may thereafter exercise (x) all voting, corporate and other rights pertaining to such Pledged Securities at any meeting of shareholders (or other equivalent body) of the relevant
Issuer or Issuers or otherwise and (y) any and all rights of conversion, exchange and subscription and any other rights, privileges or options pertaining to such Pledged Securities as if it were the absolute owner thereof (including, without
limitation, the right to exchange at its discretion any and all of the Pledged Securities upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the organizational structure of any Issuer, or upon the
exercise by any Grantor or the Administrative Agent of any right, privilege or option pertaining to such Pledged Securities, and in connection therewith, the right to deposit and deliver any and all of the Pledged Securities with any committee,
depositary, transfer agent, registrar or other designated 

  

 - 16 - 

 
agency upon such terms and conditions as the Administrative Agent may determine), all without liability except to account for property actually received by
it, but the Administrative Agent shall have no duty to any Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing. 
 (c) Each Grantor hereby authorizes and instructs each Issuer of any Pledged Securities pledged by such Grantor hereunder (and each Issuer
party hereto hereby agrees) to (i) comply with any instruction received by it from the Administrative Agent in writing that (x) states that an Event of Default has occurred and is continuing and (y) is otherwise in accordance with the
terms of this Agreement, without any other or further instructions from such Grantor, and each Grantor agrees that each Issuer shall be fully protected in so complying, and (ii) unless otherwise expressly permitted hereby, pay any dividends or
other payments with respect to the Pledged Securities directly to the Administrative Agent. 
 (d) After the occurrence and
during the continuation of an Event of Default, if the Issuer of any Pledged Securities is the subject of bankruptcy, insolvency, receivership, custodianship or other proceedings under the supervision of any Governmental Authority, then all rights
of the Grantor in respect thereof to exercise the voting and other consensual rights which such Grantor would otherwise be entitled to exercise with respect to the Pledged Securities issued by such Issuer shall cease, and all such rights shall
thereupon become vested in the Administrative Agent who shall thereupon have the sole right to exercise such voting and other consensual rights, but the Administrative Agent shall have no duty to exercise any such voting or other consensual rights
and shall not be responsible for any failure to do so or delay in so doing. 
 Section 7.02 Collections on Accounts, Etc. The
Administrative Agent hereby authorizes each Grantor to collect upon the Accounts, Instruments, Chattel Paper and Payment Intangibles subject to the Administrative Agent’s direction and control, and the Administrative Agent may curtail or
terminate said authority at any time after the occurrence and during the continuance of an Event of Default. Upon the request of the Administrative Agent at any time after the occurrence and during the continuance of an Event of Default, each
Grantor shall notify the Account Debtors that the applicable Accounts, Chattel Paper and Payment Intangibles have been assigned to the Administrative Agent for the ratable benefit of the Secured Parties and that payments in respect thereof shall be
made directly to the Administrative Agent. The Administrative Agent may in its own name or in the name of others communicate with the Account Debtors to verify with them to its satisfaction the existence, amount and terms of any Accounts, Chattel
Paper or Payment Intangibles. 
 Section 7.03 Proceeds. If required by the Administrative Agent at any time after the occurrence and
during the continuance of an Event of Default, any payments of Accounts, Instruments, Chattel Paper and Payment Intangibles, when collected or received by each Grantor, and any other cash or non-cash Proceeds received by each Grantor upon the sale
or other disposition of any Collateral, shall be forthwith (and, in any event, within two Business Days) deposited by such Grantor in the exact form received, duly indorsed by such Grantor to the Administrative Agent if required, in a special
collateral account maintained by the Administrative Agent, subject to withdrawal by the Administrative Agent for the ratable benefit of the Secured Parties only, as hereinafter provided, and, until so turned over, shall be held by 

  

 - 17 - 

 
such Grantor in trust for the Administrative Agent for the ratable benefit of the Secured Parties, segregated from other funds of any such Grantor. Each
deposit of any such Proceeds shall be accompanied by a report identifying in reasonable detail the nature and source of the payments included in the deposit. All Proceeds (including, without limitation, Proceeds constituting collections of Accounts,
Chattel Paper, Instruments) while held by the Administrative Agent (or by any Grantor in trust for the Administrative Agent for the ratable benefit of the Secured Parties) shall continue to be collateral security for all of the Obligations and shall
not constitute payment thereof until applied as hereinafter provided. At such intervals as may be agreed upon by each Grantor and the Administrative Agent, or, if an Event of Default shall have occurred and be continuing, at any time at the
Administrative Agent’s election, the Administrative Agent shall apply all or any part of the funds on deposit in said special collateral account on account of the Obligations in such order as the Administrative Agent may elect, and any part of
such funds which the Administrative Agent elects not so to apply and deems not required as collateral security for the Obligations shall be paid over from time to time by the Administrative Agent to each Grantor or to whomsoever may be lawfully
entitled to receive the same. 
 Section 7.04 Texas UCC and Other Remedies. 
 (a) If an Event of Default shall occur and be continuing, the Administrative Agent, on behalf of the Secured Parties, may exercise in its
discretion, in addition to all other rights, remedies, powers and privileges granted to them in this Agreement, the other Loan Documents, any Permitted Hedging Agreement and in any other instrument or agreement securing, evidencing or relating to
the Obligations, all rights, remedies, powers and privileges of a secured party under the Texas UCC (whether the Texas UCC is in effect in the jurisdiction where such rights, remedies, powers or privileges are asserted) or any other applicable law
or otherwise available at law or equity. Without limiting the generality of the foregoing, the Administrative Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required
by law referred to below) to or upon any Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the
Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at
public or private sale or sales, at any exchange, broker’s board or office of the Administrative Agent or any other Secured Party or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for
cash or on credit or for future delivery without assumption of any credit risk. The Administrative Agent or any other Secured Party shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private
sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Grantor, which right or equity is hereby waived and released. If an Event of Default shall occur and be continuing, each
Grantor further agrees, at the Administrative Agent’s request, to assemble the Collateral and make it available to the Administrative Agent at places which the Administrative Agent shall reasonably select, whether at such Grantor’s
premises or elsewhere. Any such sale or transfer by the Administrative Agent either to itself or to any other Person shall be absolutely free from any claim of right by Grantor, including any equity or right of redemption, stay or appraisal which
Grantor has or may have under any rule of law, regulation or statute now existing or hereafter adopted. Upon any such 

  

 - 18 - 

 
sale or transfer, the Administrative Agent shall have the right to deliver, assign and transfer to the purchaser or transferee thereof the Collateral so sold
or transferred. The Administrative Agent shall apply the net proceeds of any action taken by it pursuant to this Section 7.04, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the
care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Administrative Agent and the other Secured Parties hereunder, including, without limitation, reasonable attorneys’ fees and
disbursements, to the payment in whole or in part of the Obligations, in accordance with Section 10.02 of the Credit Agreement, and only after such application and after the payment by the Administrative Agent of any other amount required by
any provision of law, including, without limitation, Section 9.615 of the Texas UCC, need the Administrative Agent account for the surplus, if any, to any Grantor. To the extent permitted by applicable law, each Grantor waives all claims,
damages and demands it may acquire against the Administrative Agent or any other Secured Party arising out of the exercise by them of any rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law,
such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition. 
 (b) In
the event that the Administrative Agent elects not to sell the Collateral, the Administrative Agent retains its rights to dispose of or utilize the Collateral or any part or parts thereof in any manner authorized or permitted by law or in equity,
and to apply the proceeds of the same towards payment of the Obligations. Each and every method of disposition of the Collateral described in this Agreement shall constitute disposition in a commercially reasonable manner. The Administrative Agent
may appoint any Person as agent to perform any act or acts necessary or incident to any sale or transfer of the Collateral. 
 Section 7.05
Private Sales of Pledged Securities. Each Grantor recognizes that the Administrative Agent may be unable to effect a public sale of any or all the Pledged Securities, by reason of certain prohibitions contained in the Securities Act and
applicable state securities laws or otherwise, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own
account for investment and not with a view to the distribution or resale thereof. Each Grantor acknowledges and agrees that any such private sale may result in prices and other terms less favorable than if such sale were a public sale and,
notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner. The Administrative Agent shall be under no obligation to delay a sale of any of the Pledged Securities for
the period of time necessary to permit the Issuer thereof to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if such Issuer would agree to do so. Each Grantor agrees to use its best
efforts to do or cause to be done all such other acts as may reasonably be necessary to make such sale or sales of all or any portion of the Pledged Securities pursuant to this Section 7.05 valid and binding and in compliance with any and all
other applicable Governmental Requirements. Each Grantor further agrees that a breach of any of the covenants contained in this Section 7.05 will cause irreparable injury to the Administrative Agent and the other Secured Parties, that the
Administrative Agent and the other Secured Parties have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section 7.05 shall be specifically enforceable against such
Grantor, and such Grantor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants. 
  

 - 19 - 

 Section 7.06 Waiver; Deficiency. Each Grantor waives and agrees not to assert any rights or
privileges which it may acquire under the Texas UCC or any other applicable law. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay its Obligations and the
fees and disbursements of any attorneys employed by the Administrative Agent or any other Secured Party to collect such deficiency. 
 Section 7.07 Non-Judicial Enforcement. The Administrative Agent may enforce its rights hereunder without prior judicial process or judicial hearing, and to the extent permitted by law, each Grantor expressly waives any and all legal
rights which might otherwise require the Administrative Agent to enforce its rights by judicial process. 
 ARTICLE VIII 
 The Administrative Agent 
 Section 8.01
Administrative Agent’s Appointment as Attorney-in-Fact, Etc. 
 (a) Each Grantor hereby irrevocably constitutes
and appoints the Administrative Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of such Grantor and in the name of such
Grantor or in its own name, for the purpose of carrying out the terms of this Agreement, to take any and all reasonably appropriate action and to execute any and all documents and instruments which may be reasonably necessary or desirable to
accomplish the purposes of this Agreement, and, without limiting the generality of the foregoing, each Grantor hereby gives the Administrative Agent the power and right, on behalf of such Grantor, without notice to or assent by such Grantor, to do
any or all of the following: 
 (i) unless being disputed under Section 9.03(a) of the Credit Agreement, pay or discharge
taxes and Liens levied or placed on or threatened against the Collateral, effect any repairs or any insurance called for by the terms of this Agreement and pay all or any part of the premiums therefor and the costs thereof; 
 (ii) execute, in connection with any sale provided for in Section 7.04 or Section 7.05, any endorsements, assignments or other
instruments of conveyance or transfer with respect to the Collateral; and 
 (iii) (A) direct any party liable for any payment
under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to the Administrative Agent or as the Administrative Agent shall direct; (B) take possession of and indorse and collect any checks,
drafts, notes, acceptances or other instruments for the payment of moneys due under any Account, Instrument, General Intangible, Chattel Paper or Payment Intangible or with respect to any other Collateral, and to file any claim or to take any other
action or proceeding in any court of law or equity or otherwise deemed appropriate by the Administrative Agent for the purpose of collecting any all such moneys due under any Account, Instrument or General Intangible or with respect to any other
Collateral whenever payable; (C)

  

 - 20 - 

 
ask or demand for, collect, and receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect
of or arising out of any Collateral; (D) sign and indorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications, notices and other documents in connection with
any of the Collateral; (E) receive, change the address for delivery, open and dispose of mail addressed to any Grantor, and to execute, assign and indorse negotiable and other instruments for the payment of money, documents of title or other
evidences of payment, shipment or storage for any form of Collateral on behalf of and in the name of any Grantor; (F) commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect
the Collateral or any portion thereof and to enforce any other right in respect of any Collateral; (G) defend any suit, action or proceeding brought against such Grantor with respect to any Collateral; (H) settle, compromise or adjust any
such suit, action or proceeding and, in connection therewith, give such discharges or releases as the Administrative Agent may deem appropriate; and (I) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal
with any of the Collateral as fully and completely as though the Administrative Agent were the absolute owner thereof for all purposes, and do, at the Administrative Agent’s option and such Grantor’s expense, at any time, or from time to
time, all acts and things which the Administrative Agent deems necessary to protect, preserve or realize upon the Collateral and the Administrative Agent’s and the other Secured Parties’ security interests therein and to effect the intent
of this Agreement, all as fully and effectively as such Grantor might do. 
 Anything in this Section 8.01(a) to the contrary
notwithstanding, the Administrative Agent agrees that it will not exercise any rights under the power of attorney provided for in this Section 8.01(a) unless an Event of Default shall have occurred and be continuing. 
 (b) If any Grantor fails to perform or comply with any of its agreements contained herein within the applicable grace periods, the
Administrative Agent, at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement. 
 (c) The expenses of the Administrative Agent incurred in connection with actions undertaken as provided in this Section 8.01,
together with interest thereon at the Post-Default Rate from the date of payment by the Administrative Agent to the date reimbursed by the relevant Grantor, shall be payable by such Grantor to the Administrative Agent on demand. 
 (d) Each Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue and in compliance hereof. All
powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement is terminated and the security interests created hereby are released. 
 Section 8.02 Duty of Administrative Agent. The Administrative Agent’s sole duty with respect to the custody, safekeeping and physical
preservation of the Collateral in its possession, under Section 9.207 of the Texas UCC or otherwise, shall be to deal with it in the same manner as the Administrative Agent deals with similar property for its own account and shall be deemed to
have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which comparable 

  

 - 21 - 

 
secured parties accord comparable collateral. Neither the Administrative Agent, any other Secured Party nor any of their respective 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 Grantor or
any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on the Administrative Agent and the other Secured Parties hereunder are solely to protect the Administrative Agent’s
and the other Secured Parties’ interests in the Collateral and shall not impose any duty upon the Administrative Agent or any other Secured Party to exercise any such powers. The Administrative Agent and the other Secured Parties shall be
accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act
hereunder, except for their own gross negligence or willful misconduct. To the fullest extent permitted by applicable law, the Administrative Agent shall be under no duty whatsoever to make or give any presentment, notice of dishonor, protest,
demand for performance, notice of non-performance, notice of intent to accelerate, notice of acceleration, or other notice or demand in connection with any Collateral or the Obligations, or to take any steps necessary to preserve any rights against
any Grantor or other Person or ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not it has or is deemed to have knowledge of such matters. Each
Grantor, to the extent permitted by applicable law, waives any right of marshaling in respect of any and all Collateral, and waives any right to require the Administrative Agent or any other Secured Party to proceed against any Grantor or other
Person, exhaust any Collateral or enforce any other remedy which the Administrative Agent or any other Secured Party now has or may hereafter have against each Grantor, any Grantor or other Person. 
 Section 8.03 Execution of Financing Statements. Pursuant to the Texas UCC and any other applicable law, each Grantor authorizes the Administrative
Agent, its counsel or its representative, at any time and from time to time, to file or record financing statements, continuation statements, amendments thereto and other filing or recording documents or instruments with respect to the Collateral
without the signature of such Grantor in such form and in such offices as the Administrative Agent reasonably determines appropriate to perfect the security interests of the Administrative Agent under this Agreement. Additionally, each Grantor
authorizes the Administrative Agent, its counsel or its representative, at any time and from time to time, to file or record such financing statements that describe the collateral covered thereby as “all assets of the Grantor”, “all
personal property of the Grantor” or words of similar effect. A photographic or other reproduction of this Agreement shall be sufficient as a financing statement or other filing or recording document or instrument for filing or recording in any
jurisdiction. 
 Section 8.04 Authority of Administrative Agent. Each Grantor acknowledges that the rights and responsibilities of the
Administrative Agent under this Agreement with respect to any action taken by the Administrative Agent or the exercise or non-exercise by the Administrative Agent of any option, voting right, request, judgment or other right or remedy provided for
herein or resulting or arising out of this Agreement shall, as between the Administrative Agent and the other Secured Parties, be governed by the Credit Agreement and by such other agreements with respect thereto as may exist from time to time among
them, but, as between the Administrative Agent and the Grantors, the Administrative Agent shall be conclusively presumed to be acting as agent for the Secured Parties with full and valid authority so to act or refrain from acting, and no Grantor
shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

 ARTICLE IX 
 Subordination of Indebtedness 
 Section 9.01 Subordination of All Guarantor Claims. As used
herein, the term “Guarantor Claims” shall mean all debts and obligations of the Borrower or any other Grantor to any Grantor, whether such debts and obligations now exist or are hereafter incurred or arise, or whether the obligation of the
debtor thereon be direct, contingent, primary, secondary, several, joint and several, or otherwise, and irrespective of whether such debts or obligations be evidenced by note, contract, open account, or otherwise, and irrespective of the Person or
Persons in whose favor such debts or obligations may, at their inception, have been, or may hereafter be created, or the manner in which they have been or may hereafter be acquired by. After and during the continuation of an Event of Default, no
Grantor shall receive or collect, directly or indirectly, from any obligor in respect thereof any amount upon the Guarantor Claims. 
 Section 9.02 Claims in Bankruptcy. In the event of receivership, bankruptcy, reorganization, arrangement, debtor’s relief or other insolvency proceedings involving any Grantor, the Administrative Agent on behalf of the Secured
Parties shall have the right to prove their claim in any proceeding, so as to establish their rights hereunder and receive directly from the receiver, trustee or other court custodian, dividends and payments which would otherwise be payable upon
Guarantor Claims. Each Grantor hereby assigns such dividends and payments to the Administrative Agent for the benefit of the Secured Parties for application against the Obligations as provided under Section 10.02 of the Credit Agreement. Should
any Agent or Secured Party receive, for application upon the Obligations, any such dividend or payment which is otherwise payable to any Grantor, and which, as between such Grantor, shall constitute a credit upon the Guarantor Claims, then upon
payment in full of the Obligations, the intended recipient shall become subrogated to the rights of the Administrative Agent and the other Secured Parties to the extent that such payments to the Administrative Agent and the other Secured Parties on
the Guarantor Claims have contributed toward the liquidation of the Obligations, and such subrogation shall be with respect to that proportion of the Obligations which would have been unpaid if the Administrative Agent and the other Secured Parties
had not received dividends or payments upon the Guarantor Claims. 
 Section 9.03 Payments Held in Trust. In the event that
notwithstanding Section 9.01 and Section 9.02, any Grantor should receive any funds, payments, claims or distributions which is prohibited by such Sections, then it agrees: (a) to hold in trust for the Administrative Agent and the
other Secured Parties an amount equal to the amount of all funds, payments, claims or distributions so received, and (b) that it shall have absolutely no dominion over the amount of such funds, payments, claims or distributions except to pay
them promptly to the Administrative Agent, for the benefit of the Secured Parties; and each Grantor covenants promptly to pay the same to the Administrative Agent. 
 Section 9.04 Liens Subordinate. Each Grantor agrees that, until the Obligations are paid in full and the Aggregate Commitments terminated, any Liens securing payment of the Guarantor Claims shall be and remain
inferior and subordinate to any Liens securing payment of 

  

 - 23 - 

 
the Obligations, regardless of whether such encumbrances in favor of such Grantor, the Administrative Agent or any other Secured Party presently exist or are
hereafter created or attach. Without the prior written consent of the Administrative Agent, no Grantor, during the period in which any of the Obligations are outstanding or the Aggregate Commitments are in effect, shall (a) exercise or enforce
any creditor’s right it may have against any debtor in respect of the Guarantor Claims, or (b) foreclose, repossess, sequester or otherwise take steps or institute any action or proceeding (judicial or otherwise, including without
limitation the commencement of or joinder in any liquidation, bankruptcy, rearrangement, debtor’s relief or insolvency proceeding) to enforce any Lien held by it. 
 Section 9.05 Notation of Records. Upon the request of the Administrative Agent, all promissory notes and all accounts receivable ledgers or other evidence of the Guarantor Claims accepted by or held by any
Grantor shall contain a specific written notice thereon that the indebtedness evidenced thereby is subordinated under the terms of this Agreement. 
 ARTICLE X 
 Miscellaneous 
 Section 10.01 Waiver. No failure on the part of the Administrative Agent or any other Secured Party to exercise and no delay in exercising, and no course of dealing with respect to, any right, remedy, 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, remedy, power or privilege. The rights, remedies, powers and privileges provided herein are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law. The exercise by the Administrative Agent of any
one or more of the rights, powers and remedies herein shall not be construed as a waiver of any other rights, powers and remedies, including, without limitation, any rights of set-off. 
 Section 10.02 Notices. All notices and other communications provided for herein shall be given in the manner and subject to the terms of
Section 12.01 of the Credit Agreement; provided that any such notice, request or demand to or upon any Guarantor shall be addressed to such Guarantor at its notice address set forth on Schedule 1. 
 Section 10.03 Payment of Expenses, Indemnities, Etc. 
 (a) Each Grantor agrees to pay or promptly reimburse the Administrative Agent and each other Secured Party for all advances, charges, costs and expenses (including, without limitation, all costs and expenses of
holding, preparing for sale and selling, collecting or otherwise realizing upon the Collateral and all attorneys’ fees, legal expenses and court costs) incurred by any Secured Party in connection with the exercise of its respective rights and
remedies hereunder, including, without limitation, any advances, charges, costs and expenses that may be incurred in any effort to enforce any of the provisions of this Agreement or any obligation of any Grantor in respect of the Collateral or in
connection with (i) the preservation of the Lien of, or the rights of the Administrative Agent or any other Secured Party under this Agreement, (ii) any actual or attempted sale, lease, disposition, exchange, collection, compromise,

such costs and expenses incurred in any bankruptcy, reorganization, workout or other similar proceeding, or (iii) collecting against such Grantor under
the guarantee contained in Article II or otherwise enforcing or preserving any rights under this Agreement and the other Loan Documents to which such Grantor is a party. 
 (b) Each Grantor agrees to pay, and to save the Administrative Agent and the other Secured Parties harmless from, any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever (including, without limitation, court costs and attorneys’ fees, any and all liabilities with respect to, or
resulting from any delay in paying, any and all stamp, excise, sales or other taxes which may be payable or determined to be payable with respect to any of the Collateral or in connection with any of the transactions contemplated by this Agreement)
incurred because of, incident to, or with respect to, the Collateral (including, without limitation, any exercise of rights or remedies in connection therewith) or the execution, delivery, enforcement, performance and administration of this
Agreement, to the extent the Borrower would be required to do so pursuant to Section 12.03 of the Credit Agreement. All amounts for which any Grantor is liable pursuant to this Section 10.03 shall be due and payable by such Grantor to the
Secured Parties upon demand. 
 Section 10.04 Amendments in Writing. None of the terms or provisions of this Agreement may be waived,
amended, supplemented or otherwise modified except in accordance with Section 12.02 of the Credit Agreement. 
 Section 10.05
Successors and Assigns. This Agreement shall be binding upon the successors and assigns of each Grantor and shall inure to the benefit of the Administrative Agent and the other Secured Parties and their successors and assigns; provided that
except as set forth in Section 8.14 or Section 9.13 of the Credit Agreement, no Grantor may assign, transfer or delegate any of its rights or obligations under this Agreement without the prior written consent of the Administrative Agent
and the Lenders. 
 Section 10.06 Invalidity. In the event that any one or more of the provisions contained in this Agreement or in
any of the Loan Documents to which a Grantor is a party shall, for any reason, be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement or such
other Loan Document. 
 Section 10.07 Counterparts. This Agreement may be executed in any number of counterparts, all of which taken
together shall constitute one and the same instrument and any of the parties hereto may execute this Agreement by signing any such counterpart. 
 Section 10.08 Survival. The obligations of the parties under Section 10.03 shall survive the repayment of the Loans and the termination of the Letters of Credit, Permitted Hedging Agreements, Credit Agreement and Aggregate
Commitments. To the extent that any payments on the Obligations 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 Obligations so satisfied shall be revived and continue as if such payment or proceeds 

  

 - 25 - 

 
had not been received and the Administrative Agent’s and the other Secured Parties’ Liens, security interests, rights, powers and remedies under
this Agreement and each Security Instrument shall continue in full force and effect. In such event, each Security Instrument shall be automatically reinstated and each Grantor shall take such action as may be reasonably requested by the
Administrative Agent and the other Secured Parties to effect such reinstatement. 
 Section 10.09 Captions. Captions and section
headings appearing herein are included solely for convenience of reference and are not intended to affect the interpretation of any provision of this Agreement. 
 Section 10.10 No Oral Agreements. The Loan Documents (other than the Letters of Credit) embody the entire agreement and understanding between the parties and supersede all other agreements and understandings
between such parties relating to the subject matter hereof and thereof. The Loan Documents represent the final agreement between the parties and may not be contradicted by evidence of prior, contemporaneous or subsequent oral agreements of the
parties. There are no unwritten oral agreements between the parties. 
 Section 10.11 Governing Law; Submission to Jurisdiction.

 (a) This Agreement shall be governed by, and construed in accordance with, the laws of the state of Texas. 
 (b) Any legal action or proceeding with respect to this Agreement or any other Loan Documents to which a Grantor is a party shall be
brought in the courts of the State of Texas or of the United States of America for the Southern District of Texas, and each of the Lenders, the Administrative Agent and the Grantors 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 of the Lenders, the Administrative Agent and the Grantors 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 the Administrative Agent or any Lender from obtaining jurisdiction over such Grantor in any court otherwise having jurisdiction. 
 (c) Each of the Lenders, the Administrative Agent and the Grantors irrevocably consents to the service of process of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof
by registered or certified mail, postage prepaid, to such Person at the address specified on its signature page of this Agreement or the Credit Agreement, as applicable, such service to become effective thirty (30) days after such mailing.
Nothing herein shall affect the right of the Administrative Agent or any Lender or any holder of a Note or Grantor to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against such Grantor in
any other jurisdiction. 
 (d) Each Grantor and each Lender hereby (i) irrevocably and unconditionally waive, to the
fullest extent permitted by law, trial by jury in any legal action or proceeding relating to this Agreement or any other Loan Document and for any counterclaim therein; (ii) irrevocably waive, to the maximum extent not prohibited by law, any
right it may have to claim or recover in 

  

 - 26 - 

 
any such litigation any special, exemplary, punitive or consequential damages, or damages other than, or in addition to, actual damages; (iii) certify
that no party hereto nor any representative or agent of counsel for any party hereto has represented, expressly or otherwise, or implied that such party would not, in the event of litigation, seek to enforce the foregoing waivers, and
(iv) acknowledge that it has been induced to enter into this Agreement, the Loan Documents and the transactions contemplated hereby and thereby by, among other things, the mutual waivers and certifications contained in this Section 10.11.

 Section 10.12 Acknowledgments. Each Grantor hereby acknowledges that: 
 (a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents to which it
is a party; 
 (b) neither the Administrative Agent nor any other Secured Party has any fiduciary relationship with or duty to
any Grantor arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between the Grantors, on the one hand, and the Administrative Agent and the other Secured Parties, on the other hand, in
connection herewith or therewith is solely that of debtor and creditor; and 
 (c) no joint venture is created hereby or by
the other Loan Documents or otherwise exists by virtue of the transactions contemplated hereby among the Secured Parties or among the Grantors and the Lenders. 
 (d) Each of the parties hereto specifically agrees that it has a duty to read this Agreement and the Security Instruments and agrees that
it is charged with notice and knowledge of the terms of this Agreement and the Security Instruments; 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 Security Instruments; and has received the advice of its attorney in entering into this
Agreement and the Security Instruments; and that it recognizes that certain of the terms of this Agreement and the Security Instruments 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 Security Instruments on the basis that the party
had no notice or knowledge of such provision or that the provision is not “conspicuous.” 
 (e) Each Grantor
warrants and agrees that each of the waivers and consents set forth in this Agreement are made voluntarily and unconditionally after consultation with outside legal counsel and with full knowledge of their significance and consequences, with the
understanding that events giving rise to any defense or right waived may diminish, destroy or otherwise adversely affect rights which such Grantor otherwise may have against the Borrower, any other Grantor, the Secured Parties or any other Person or
against any collateral. If, notwithstanding the intent of the parties that the terms of this Agreement shall control in any and all circumstances, any such waivers or consents are determined to be unenforceable under applicable law, such waivers and
consents shall be effective to the maximum extent permitted by law. 
  

 - 27 - 

 Section 10.13 Additional Grantors. Each Subsidiary of the Borrower that is required to become a
party to this Agreement pursuant to Section 8.11 of the Credit Agreement and is not a signatory hereto shall become a Grantor for all purposes of this Agreement upon execution and delivery by such Subsidiary of an Assumption Agreement in the
form of Annex I hereto. 
 Section 10.14 Set-Off. Each Grantor agrees that, in addition to (and without limitation of) any right of
set-off, bankers’ lien or counterclaim a Secured Party may otherwise have, each Secured Party shall have the right and be entitled (after consultation with the Administrative Agent), at its option, to offset (i) balances held by it or by
any of its Affiliates for account of any Grantor or any Subsidiary at any of its offices, in Dollars or in any other currency, and (ii) amounts due and payable to such Lender (or any Affiliate of such Lender) under any Permitted Hedging
Agreement, against any principal of or interest on any of such Secured Party’s Loans, or any other amount due and payable to such Secured Party hereunder, which is not paid when due (regardless of whether such balances are then due to such
Person), in which case it shall promptly notify the Borrower and the Administrative Agent thereof, provided that such Secured Party’s failure to give such notice shall not affect the validity thereof. 
 Section 10.15 Releases. 
 (a) Release Upon Payment in Full. The grant of a security interest hereunder and all of rights, powers and remedies in connection herewith shall remain in full force and effect until the Administrative Agent has
(i) retransferred and delivered all Collateral in its possession to the Grantors, and (ii) executed a written release or termination statement and reassigned to the Grantors without recourse or warranty any remaining Collateral and all
rights conveyed hereby. Upon the complete payment of the Obligations, the termination of the Letters of Credit, Permitted Hedging Agreements secured hereby, Credit Agreement and the Aggregate Commitments and the compliance by the Grantors with all
covenants and agreements hereof, the Administrative Agent, at the written request and expense of the Borrower, will promptly release, reassign and transfer the Collateral to the Grantors and declare this Agreement to be of no further force or
effect. 
 (b) Further Assurances. If any of the Collateral shall be sold, transferred or otherwise disposed of by any
Grantor in a transaction permitted by the Credit Agreement, then the Administrative Agent, at the request and sole expense of such Grantor, shall promptly execute and deliver to such Grantor all releases or other documents reasonably necessary or
desirable for the release of the Liens created hereby on such Collateral and the capital stock of such Grantor. At the request and sole expense of the Borrower, a Grantor shall be released from its obligations hereunder in the event that all the
capital stock of such Grantor shall be sold, transferred or otherwise disposed of in a transaction permitted by the Credit Agreement; provided that the Borrower shall have delivered to the Administrative Agent, at least ten Business Days prior to
the date of the proposed release, a written request for release identifying the relevant Grantor and the terms of the sale or other disposition in reasonable detail, including the price thereof and any expenses in connection therewith, together with
a certification by the Borrower stating that such transaction is in compliance with the Credit Agreement and the other Loan Documents. 
  

 - 28 - 

 (c) Retention in Satisfaction. Except as may be expressly applicable pursuant to
Section 9.620 of the Texas UCC, no action taken or omission to act by the Administrative Agent or the other Secured Parties hereunder, including, without limitation, any exercise of voting or consensual rights or any other action taken or
inaction, shall be deemed to constitute a retention of the Collateral in satisfaction of the Obligations or otherwise to be in full satisfaction of the Obligations, and the Obligations shall remain in full force and effect, until the Administrative
Agent and the other Secured Parties shall have applied payments (including, without limitation, collections from Collateral) towards the Obligations in the full amount then outstanding or until such subsequent time as is provided in
Section 10.15(a). 
 Section 10.16 Reinstatement. The obligations of each Grantor under this Agreement (including, without
limitation, with respect to the guarantee contained in Article II and the provision of collateral herein) shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is
rescinded or must otherwise be restored or returned by the Administrative Agent or any other Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Borrower or any Grantor, or upon or as a result of the
appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Borrower or any Grantor or any substantial part of its property, or otherwise, all as though such payments had not been made. 
 Section 10.17 Acceptance. Each Grantor hereby expressly waives notice of acceptance of this Agreement, acceptance on the part of the
Administrative Agent and the other Secured Parties being conclusively presumed by their request for this Agreement and delivery of the same to the Administrative Agent.
