lesser of the amount of such Debt and the maximum stated amount of such guarantee or assurance against loss; (h) all obligations or undertakings of such Person to maintain or cause to be maintained the financial position or covenants of others or to
purchase the Debt or Property of others; (i) obligations to deliver commodities, goods or services, including, without limitation, Hydrocarbons, in consideration of one or more advance payments, other than gas balancing arrangements in the ordinary

of any Person shall not include any accounts payable, accrued expenses or other liabilities of such Person to trade creditors arising in the ordinary course of business (including guarantees thereof or instruments evidencing such liabilities) which
are not greater than 120 days past the invoice or billing date or, if greater than 120 days past the invoice or billing date, are being contested in good faith by appropriate proceedings if reserves adequate under GAAP shall have been established

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

Section 2.02 Loans and Borrowings. 
  
 (a) Borrowings; Several Obligations. Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance
with their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments are several and no Lender shall be responsible for
any other Lender’s failure to make Loans as required. 
  
 (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. No such
designation or transfer shall result in any 

  

 23 

 
liability on the part of the Borrower for increased costs or expenses resulting solely from such designation or transfer (except any such transfer which is
made by a Lender pursuant to Section 5.04 or Section 5.05, or otherwise for the purpose of complying with any Governmental Requirement). Increased costs for expenses resulting from a change in law occurring subsequent to any such designation or
transfer shall be deemed not to result solely from such designation or transfer. 
  
 (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 $5,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $100,000 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 eight (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. The Loans made by each Lender shall be evidenced by a single promissory note of the Borrower in substantially the form of Exhibit A,
dated, in the case of (i) any Lender party hereto as of the date of this Agreement, as of the Effective Date 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. 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. 
  
 (e) On the Effective Date (or as soon as
practicable after the Effective Date with respect to (iii)): 
  
 (i) the Borrower shall pay all accrued and unpaid commitment fees, break funding fees under Section 5.02, if any, associated with refunded “Eurodollar Loans” outstanding under the Existing Credit Agreement and all other fees that
are outstanding under the Existing Credit Agreement for the account of each “Lender” or “Issuing Bank” under the Existing Credit Agreement; 
  

 24 

 (ii) each “ABR Loan” outstanding under the Existing Credit Agreement shall be deemed to be
repaid with the proceeds of a new ABR Loan under this Agreement; and each “Eurodollar Loan” outstanding under the Existing Credit Agreement shall be repaid with the proceeds of a new Eurodollar Loan under this Agreement made by the Lenders
in accordance with their respective Applicable Percentage of the Borrowing; 
  
 (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 any
promissory note issued by the Borrower to it under the Existing Credit Agreement, marked “canceled” or otherwise similarly defaced; 
  
 (iv) any “Letters of Credit” issued under the Existing Credit Agreement shall be deemed issued under this Agreement (without payment of
additional fees); and 
  
 (v) the Existing Credit Agreement and
the commitments thereunder shall be superceded by this Agreement and such commitments shall terminate. 
  
 (f) It is the intent of the parties hereto that this Agreement not constitute a novation of the obligations and liabilities existing under the Existing
Credit Agreement or evidence repayment of any such obligations and liabilities and that this Agreement amend and restate in its entirety the Existing Credit Agreement and re-evidence the obligations of the Borrower outstanding thereunder.

 25 

 (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. No such conversion or
continuation shall be deemed the making of a new Borrowing for purposes of this Agreement, including without limitation ARTICLE VI. 
  
 (b) Interest Election Requests. To make an election pursuant to this Section 2.04, the Borrower shall notify the Administrative Agent of such
election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such
telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by
the Borrower. 
  
 (c) Information in Interest Election
Requests. Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02: 
  
 (i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof,
the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to Section 2.04(c)(iii) and (iv) shall be specified for each resulting Borrowing); 
  

 26 

 (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 2:00 p.m., New York City time, to the account of the Administrative Agent most recently designated by it for such purpose
by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Administrative Agent in Houston, Texas
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 that
made such LC Disbursement. Nothing herein shall be deemed to obligate any Lender to obtain the funds for its Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for its
Loan in any particular place or manner. 
  

 27 

 (b) Presumption of Funding by the Lenders. Unless the Administrative Agent shall have received
notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such
share available on such date in accordance with Section 2.05(a) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing
available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount 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 $1,000,000 and not less than $5,000,000 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. 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 first Redetermination Date, the amount of the
Borrowing Base shall be $750,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments from time to time pursuant to Section 8.13(c), Section 9.02(k) or Section 9.13. 
  

 28 

 (b) Scheduled and Interim Redeterminations. Subject to Section 2.07(d), the Borrowing Base shall
be redetermined (a “Scheduled Redetermination”) on May 1st and November 1st of each year, commencing November 1, 2005. In addition, the Borrower may, by notifying the Administrative Agent thereof, and the Administrative Agent may,
at the direction of the Super-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. 
  
 (ii) The Administrative Agent shall notify the Borrower and the Lenders of the Proposed Borrowing Base (the
“Proposed Borrowing Base Notice”): 
  
 (A) in
the case of a Scheduled Redetermination (1) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on or before the
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

  
 (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. 
  

 29 

 (iii) Any Proposed Borrowing Base that would increase the Borrowing Base then in effect
must be approved or deemed to have been approved by all of the Lenders 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 Super-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, all of the Lenders, in the case of a Proposed Borrowing Base that would increase the Borrowing Base then in effect, or the Super-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, all of the Lenders or the Super-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 a number of Lenders sufficient to constitute all of the Lenders or the Super-majority Lenders, as applicable, and such amount shall become the new Borrowing Base, effective on the date
specified in Section 2.07(d). 
  
 (d) Effectiveness of a
Redetermined Borrowing Base. After a redetermined Borrowing Base is approved or is deemed to have been approved by all of the Lenders or the Super-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, each
Issuing Bank and the Lenders: 
  
 (i) in the case of a Scheduled
Redetermination, (A) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on the 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), Section 9.02(k)
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. 
  

 30 

 Section 2.08 Letters of Credit. 
  
 (a) General. Subject to the terms and conditions set forth herein, the Borrower may request any Issuing Bank to issue
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 such 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, an 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 any 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 issued by such Issuing Bank 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, the current total Revolving Credit Exposures (without regard to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit) and the pro forma total Revolving
Credit Exposures (giving effect to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit). 
  
 Each notice shall constitute a representation that, after giving effect to the requested issuance, amendment, renewal or extension, as applicable, (i) the LC Exposure
shall not exceed the LC Commitment and (ii) the total Revolving Credit Exposures shall not exceed the total Commitments (i.e. the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base). 
  
 If requested by any Issuing Bank, the Borrower also shall submit a letter of
credit application on such Issuing Bank’s standard form in connection with any request for a Letter of Credit. 
  

 31 

 (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 that issues such Letter of Credit or the Lenders, each Issuing Bank that issues a Letter of Credit
hereunder hereby grants to each Lender, and each Lender hereby acquires from such 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 any Issuing Bank that issues a Letter of Credit hereunder, such
Lender’s Applicable Percentage of each LC Disbursement made by such 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 any
Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit issued by such Issuing Bank, 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 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. For purposes of the first sentence of Section 2.01, the amount of the ABR Borrowing shall be
considered, but the amount of the LC Disbursement to be concurrently reimbursed shall not be considered. 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 

  

 32 

 
Administrative Agent shall promptly pay to the Issuing Bank that issued such Letter of Credit 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 that issued such Letter of Credit or, to the extent that
Lenders have made payments pursuant to this Section 2.08(e) to reimburse such Issuing Bank, then to such Lenders and such Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this Section 2.08(e) to reimburse an
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 any Issuing Bank under a Letter of Credit issued by such Issuing Bank against presentation of a draft or other document that does not comply
with the terms of such Letter of Credit or any Letter of Credit Agreement, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.08(f), constitute a
legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor any 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 any Issuing Bank; provided that the foregoing shall not be construed to excuse any 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 such 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 any Issuing Bank (as
finally determined by a court of competent jurisdiction), such Issuing Bank shall be deemed to have exercised all requisite care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties
agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank that issued such Letter of Credit may, in its sole discretion, either accept and make
payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the
terms of such Letter of Credit. 
  

 33 

 (g) Disbursement Procedures. Each Issuing Bank shall, promptly following its receipt thereof,
examine all documents purporting to represent a demand for payment under a Letter of Credit issued by such Issuing Bank. Such Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such
demand for payment and whether such 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 such Issuing Bank
and the Lenders with respect to any such LC Disbursement. 
  
 (h)
Interim Interest. If any Issuing Bank shall make any LC Disbursement, then, until the Borrower shall have reimbursed such 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 such Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.08(e) to reimburse such Issuing Bank shall be for the account
of such Lender to the extent of such payment. 
  
 (i)
Replacement of an Issuing Bank. Any Issuing Bank may be replaced or resign at any time by written agreement among the Borrower, the Administrative Agent, such retiring or replaced Issuing Bank and, in the case of a replacement, the successor
Issuing Bank. The Administrative Agent shall notify the Lenders of any such resignation or replacement of an Issuing Bank. At the time any such resignation or replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the
account of the retiring or replaced Issuing Bank pursuant to Section 3.05(b). In the case of the replacement of an Issuing Bank, from and after the effective date of such replacement, (i) the successor Issuing Bank shall have all the rights and
obligations of the replaced Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to “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 resignation or replacement of an Issuing Bank hereunder, the retiring or replaced Issuing Bank shall remain a party hereto and shall continue to have
all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such resignation or 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 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 

  

 34 

 
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 each 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, any Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason
whatsoever. Such deposit shall be held as collateral securing the payment and performance of the Borrower’s and the Guarantor’s obligations under this Agreement and the other Loan Documents. The Administrative Agent shall have exclusive
dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent
and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse,
on a pro rata basis, each 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. In the event of any such payment by the Borrower of amounts
contingently owing under outstanding Letters of Credit and in the event that thereafter drafts or other demands for payment complying with the terms of such Letters of Credit are not made on or prior to the respective expiration dates thereof, the
Administrative Agent agrees, if no Event of Default is then continuing or if no other amounts are then outstanding under this Agreement, the Notes or the Loan Documents, to remit to the Borrower amounts for which the contingent obligations evidenced
by the Letters of Credit have ceased. 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. 
  

 35 

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

 36 

 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; 
  
 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 (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 any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash
collateral as provided in Section 2.08(j). 
  

 37 

 (ii) Upon any redetermination of or adjustment to the amount of the Borrowing Base in accordance with
Section 2.07 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 any
excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.08(j). The Borrower
shall be obligated to make such prepayment and/or deposit of cash collateral within sixty (60) 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. 
  
 (iii) Upon any adjustments to the Borrowing Base pursuant to 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 any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on
behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.08(j). The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral on the date it or any Subsidiary receives
proceeds as a result of such disposition; provided that all payments required to be made pursuant to this Section 3.04(c)(iii) must be made on or prior to the Termination Date. 
  
 (iv) 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 Effective Date 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 

  

 38 

 
on the first such date to occur after the Effective Date. All commitment fees 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 Effective Date 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 each Issuing Bank a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of that portion of the LC Exposure attributable to such Issuing Bank (excluding any portion thereof
attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date 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 attributable to
such Issuing Bank, provided that in no event shall such fee be less than $125 during any quarter, and (iii) to each 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 Effective Date; 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 an
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 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 (for purposes of computing interest and
fees, each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day), 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 

  

 39 

 
succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices specified in
Section 12.01, except payments to be made directly to an Issuing Bank as expressly provided herein and except that payments pursuant to Section 5.01, Section 5.02, Section 5.03 and Section 12.03 shall be made directly to the Persons entitled
thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a
Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in
dollars. 
  
 (b) Application of Insufficient Payments. If
at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first,
towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed
LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties. 
  
 (c) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or
otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations
in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) 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 any Issuing Bank that the Borrower will not make such payment, the
Administrative Agent may assume that the Borrower has made such 

  

 40 

 
payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or such 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 such 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 such 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 (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; Illegality

  
 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 

  

 41 

 
reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or otherwise, but not including Excluded Taxes), 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 any 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 such Issuing Bank’s capital or on the capital of such Lender’s or such 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 such Issuing Bank, to a level below that which such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company could have
achieved but for such Change in Law (taking into consideration such Lender’s or such Issuing Bank’s policies and the policies of such Lender’s or such Issuing Bank’s holding company with respect to capital adequacy), then from
time to time the Borrower will pay to such Lender or such Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company for
any such reduction suffered. 
  
 (c) Certificates. A
certificate of a Lender or any Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or such 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 such Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof. 
  
 (d) Effect of Failure or Delay in Requesting Compensation. Failure or
delay on the part of any Lender or any Issuing Bank to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such compensation; provided that the Borrower
shall not be required to compensate a Lender or an 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 such 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 such 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, (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 (exclusive of any lost profits or opportunity costs). In 

  

 42 

 
the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if
any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the
last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such
principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. 
  
 A certificate of any Lender setting forth any amount or amounts that such Lender is entitled
to receive pursuant to this Section 5.02 shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

  
 Section 5.03 Taxes. 
  
 (a) Payments Free of Taxes. Any and all payments by or on account of
any obligation of the Borrower or any Guarantor under any Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower 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(a)), 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 shall make such deductions and (iii) the Borrower 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 each
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 such 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; provided that the Borrower shall not be required to indemnify the
Administrative Agent, any Lender or any Issuing Bank for any amounts under this Section 5.03(c) to the extent that such Person fails to notify the Borrower of its intent to make a claim for indemnification under this Section 5.03(c) within 180 days
after a claim is asserted against such Person by the relevant Governmental Authority. A certificate of the Administrative Agent, a Lender or an 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. 
  

 43 

 (d) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other
Taxes by the Borrower 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 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 Section 5.03 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(f)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. 
  
 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 solely as a result of such designation or
assignment. 
  

 44 

 (b) Replacement of Lenders. 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, or if any Lender defaults in its obligation to fund Loans hereunder or if any Lender has asserted
that any adoption or change of the type described in Section 5.05 has occurred, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in Section 12.04(b)), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a
Lender accepts such assignment); provided that (i) if such assignee is not a Lender, the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall
have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such
outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 5.01 or payments required to be made pursuant
to Section 5.03, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the
circumstances entitling the Borrower to require such assignment and delegation cease to apply. 
  
 Section 5.05 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its applicable lending office to honor its obligation to make or maintain
Eurodollar Loans either generally or having a particular Interest Period hereunder, then (a) such Lender shall promptly notify the Borrower and the Administrative Agent thereof and such Lender’s obligation to make such Eurodollar Loans shall be
suspended (the “Affected Loans”) until such time as such Lender may again make and maintain such Eurodollar Loans and (b) all Affected Loans which would otherwise be made by such Lender shall be made instead as ABR Loans (and, if
such Lender so requests by notice to the Borrower and the Administrative Agent, all Affected Loans of such Lender then outstanding shall be automatically converted into ABR Loans on the date specified by such Lender in such notice) and, to the
extent that Affected Loans are so made as (or converted into) ABR Loans, all payments of principal which would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its ABR Loans.

 ARTICLE 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 
  

 48 

 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. 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, fraudulent transfer or conveyance, 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 and an implied covenant of good faith and fair dealing. 
  
 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
contemplated thereby, except such as have been obtained or made and are in full force and effect other than (i) the recording and filing of the Security Instruments as required by this Agreement, (ii) filings, consents or approvals required for the

have an adverse effect on the enforceability of the Loan Documents, (b) will not violate (i) the charter, by-laws or other organizational documents of the Borrower or any Restricted Subsidiary or (ii) any applicable law or regulation or any order of
any Governmental Authority applicable to or binding upon the Borrower or any Restricted Subsidiary which would reasonably be expected to have a Material Adverse Effect, (c) will not violate or result in a default under any indenture, agreement or
other instrument pursuant to which any Material Indebtedness is outstanding, including the Indentures, 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 that could reasonably be expected to have a Material Adverse Effect 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 7.06 Environmental Matters. Except as disclosed
in the Borrower’s Annual Report on Form 10-K for the fiscal year ended December 31, 2004, and as could not be reasonably expected to have a Material Adverse Effect (or with respect to (c), (d) and (e) below, where the failure to take such
actions could not be reasonably expected to have a Material Adverse Effect): 
  
 (a) neither any Property of the Borrower or any Restricted Subsidiary nor the operations conducted thereon violate any order or requirement of any court or Governmental Authority or any Environmental Laws. 

 

 50 

 (b) no Property of the Borrower or any Restricted Subsidiary nor the operations currently conducted
thereon or, to the knowledge of the Borrower, by any prior owner or operator of such Property or operation, are in violation of or subject to any existing, pending or threatened action, suit, investigation, inquiry or proceeding by or before any

are not the subject of any existing, pending or threatened action, investigation or inquiry by any Governmental Authority in connection with any Environmental Laws. 
  
 (e) the Borrower has taken all steps reasonably necessary to determine and has determined that no oil, hazardous substances,
solid waste or oil and gas waste, have been disposed of or otherwise released and there has been no threatened release of any oil, hazardous substances, solid waste or oil and gas waste on or to any Property of the Borrower or any Restricted

 (f) to the extent applicable, all Property of the Borrower and each Restricted Subsidiary currently satisfies all design,

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

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

 51 

 (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 which any Material Indebtedness is outstanding or by which the Borrower or any Restricted Subsidiary or any of their Properties is bound. 
  
 (c) No Default has occurred and is continuing. 
  
 Section 7.08 Investment Company Act. Neither the Borrower nor any Subsidiary is an “investment company” or
a company “controlled” by an “investment company,” within the meaning of, or subject to regulation under, the Investment Company Act of 1940, as amended. 
  
 Section 7.09 Public Utility Holding Company Act. Neither the Borrower nor any Subsidiary is a “holding
company,” or a “subsidiary company” of a “holding company,” or an “affiliate” of a “holding company” or of a “subsidiary company” of a “holding company,” or a “public
utility” within the meaning of, or subject to regulation under, the Public Utility Holding Company Act of 1935, as amended. 
  
 Section 7.10 Taxes. Each of the Borrower and its Subsidiaries has timely filed or caused to be filed all federal income and other material Tax
returns and reports required to have been filed (or obtained extensions with respect thereto) and has paid or caused to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate
proceedings and for which the Borrower or such Subsidiary, as applicable, has set aside on its books adequate reserves in accordance with GAAP or (b) to the extent that the failure to do so could not reasonably be expected to result in a Material
Adverse Effect. The charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of Taxes and other governmental charges are, in the reasonable opinion of the Borrower, adequate. No action to enforce any Tax Lien has
been commenced. 
  
 Section 7.11 ERISA. The Borrower and
the ERISA Affiliates have fulfilled their respective obligations under the minimum funding standards of ERISA and the Code with respect to each Plan and are in compliance in all material respects with the presently applicable provisions of ERISA and
the Code, and have not incurred any liability to the PBGC or any Plan or Multiemployer Plan (other than to make contributions in the ordinary course of business) which liability could reasonably be expected to have a Material Adverse Effect.

  
 Section 7.12 Disclosure; No Material Misstatements.
None of the reports, financial statements, certificates or other written 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 
  

 52 

 which they were made, not misleading (other than omissions that pertain to matters of a general economic nature or
matters of public knowledge that generally affect any of the industry segments of the Borrower or its Subsidiaries); provided that, with respect to projected financial information, the Borrower represents only that such information was prepared in
good faith based upon assumptions believed to be reasonable at the time. There is no fact peculiar to the Borrower or any Restricted Subsidiary which could reasonably be expected to have a Material Adverse Effect or in the future is reasonably
likely to have a Material Adverse Effect and which has not been set forth in this Agreement or the Loan Documents or the other documents, certificates and written statements furnished to the Administrative Agent or the Lenders by or on behalf of the
Borrower or any Restricted Subsidiary prior to, or on, the date hereof in connection with the transactions contemplated hereby. There are no statements or conclusions in any Reserve Report which are based upon or include misleading information or
fail to take into account material information regarding the matters reported therein, it being understood that projections concerning volumes attributable to the Oil and Gas Properties and production and cost estimates contained in each Reserve
Report are necessarily based upon professional opinions, estimates and projections and that the Borrower and the Restricted Subsidiaries do not warrant that such opinions, estimates and projections will ultimately prove to have been accurate.

  
 Section 7.13 Insurance. The Borrower has, and has
caused all of its Restricted Subsidiaries to have, (a) all insurance policies sufficient for the compliance by each of them with all material Governmental Requirements and all material agreements and (b) insurance coverage in at least amounts and
against such risk (including, without limitation, public liability) that are usually insured against by companies similarly situated and engaged in the same or a similar business for the assets and operations of the Borrower and its Restricted
Subsidiaries. The Administrative Agent and the Lenders have been named as additional insureds in respect of such liability insurance policies and the Administrative Agent has been named as loss payee with respect to Property loss insurance.

  
 Section 7.14 Restriction on Liens. Except as permitted
by Section 9.17, neither the Borrower nor any of the Restricted Subsidiaries is a party to any material agreement or arrangement, or subject to any order, judgment, writ or decree, which either restricts or purports to restrict its ability to grant
Liens to the Administrative Agent and the Lenders on or in respect of their Properties to secure the Indebtedness and the Loan Documents. 
  
 Section 7.15 Subsidiaries. Except as set forth on Schedule 7.15 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 7.15, the Borrower has no Subsidiaries. Schedule 7.15 identifies each Subsidiary as either Restricted or Unrestricted, and each Restricted Subsidiary on such schedule is a
Wholly-Owned Subsidiary. The Borrower has no Foreign Subsidiaries, except as set forth in Schedule 7.15. 
  
 Section 7.16 Location of Business and Offices. As of the Effective Date, 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 Plains Exploration & Production Company; and the organizational identification number of the Borrower in its jurisdiction of organization is 3569131. As of the

its principal place of business and chief executive office is stated on Schedule 7.15. 
  

 53 

 Section 7.17 Properties; Titles, Etc. 
  
 (a) Except as disclosed in Schedule 7.17, 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 that are 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, 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 would affect in any material respect the conduct of the business of the Borrower and the Restricted Subsidiaries, taken as a whole. 
  
 (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) 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. 
  

 54 

 Section 7.18 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 Government Requirements and in conformity with the provisions of all leases, subleases or other contracts comprising a part of the Hydrocarbon Interests and other contracts and agreements forming a part of the Oil and Gas
Properties of the Borrower and its Restricted Subsidiaries. Specifically in connection with the foregoing, except for those as could not be reasonably expected to have a Material Adverse Effect, (i) no Oil and Gas Property of the Borrower or its
Restricted Subsidiaries 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 its Restricted Subsidiaries is deviated from the vertical more than the maximum permitted by Government 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 its
Restricted Subsidiaries, as applicable. 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 7.18 could not reasonably be expect to have a Material Adverse Effect). 
  
 Section 7.19 Gas Imbalances, Prepayments. Except as set forth on
Schedule 7.19 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 two bcf of gas (on an mcf equivalent basis) in the aggregate. 
  
 Section 7.20 Marketing of Production. Except for contracts listed and
in effect on the date hereof on Schedule 7.20, 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 90 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. 
  

 55 

 Section 7.21 Swap Agreements. Schedule 7.21, as of the Effective Date, and after the Effective
Date, 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.

  
 Section 7.22 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 and for general corporate purposes. 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 7.23 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 does not believe that it will have incurred, 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 7.24
Designated Senior Indebtedness. The Indebtedness of the Borrower constitutes “Senior Indebtedness” and “Designated Senior Indebtedness,” and the Indebtedness of each Guarantor under the Loan Documents to which it is a
party constitutes “Guarantor Senior Indebtedness”, in each case, under and as defined in the Senior Subordinated Indenture, and, if applicable, under any Permitted Additional Indenture (using such similar terms as therein defined). 

  
 ARTICLE VIII 
 Affirmative Covenants

payable under the Loan Documents shall have been paid in full and all Letters of Credit shall have expired or terminated and all LC Disbursements shall have been reimbursed, the Borrower covenants and agrees with the Lenders that:

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) to the best of his knowledge the information contained in the Reserve Report and
any other information delivered in connection therewith is true and correct, except 
  

 63 

 that with respect to the projections in the Reserve Report, the Borrower only represents that such projections were
prepared in good faith based upon assumptions believed to be reasonable at this time, (ii) except as set forth in Schedule 7.17, 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 7.19 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 the percentage of the Borrowing Base that the value of such Mortgaged Properties represent in compliance
with Section 8.14(a). 
  
 Section 8.13 Title Information.

  
 (a) If requested by the Administrative Agent, on or before
the delivery to the Administrative Agent and the Lenders of each Reserve Report required by Section 8.12(a), the Borrower will deliver title information in form and substance acceptable to the Administrative Agent covering enough of the Oil and Gas
Properties evaluated by such Reserve Report that were not included in the immediately preceding Reserve Report, so that the Administrative Agent shall have received together with title information previously delivered to the Administrative Agent,
satisfactory title information on at least 80% of the 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 60 days of notice from the
Administrative Agent that title defects or exceptions exist with respect to such additional Properties, either (i) cure any such title defects or exceptions (including defects or exceptions as to priority) which are not permitted by Section 9.03
raised by such information, (ii) substitute acceptable Mortgaged Properties with no title defects or exceptions except for Excepted Liens (other than Excepted Liens described in clauses (e), (g) and (h) of such definition) having an equivalent value
or (iii) deliver title information in form and substance acceptable to the Administrative Agent so that the Administrative Agent shall have received, together with title information previously delivered to the Administrative Agent, satisfactory
title information on at least 80% of the value of the Oil and Gas Properties evaluated by such Reserve Report. 
  
 (c) If the Borrower is unable to cure any title defect requested by the Administrative Agent or the Lenders to be cured within the 60-day period or the
Borrower does not comply with the requirements to provide acceptable title information covering 80% of the 
  

 64 

 value 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 60-day period has elapsed, such unacceptable
Mortgaged Property, shall not count towards the 80% requirement, and the Administrative Agent may send a notice to the Borrower and the Lenders that the then outstanding Borrowing Base shall be reduced by an amount as determined by the Majority
Lenders to cause the Borrower to be in compliance with the requirement to provide acceptable title information on 80% 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 (provided that Excepted Liens of the type described in clauses (a) to (d) and (f) of the definition thereof may exist, but subject to the provisos at the end of such definition) on
additional Oil and Gas Properties not already subject to a Lien of the Security Instruments such that after giving effect thereto, the Mortgaged Properties will represent at least 80% of such 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. 
  
 (b) The Borrower shall cause each Domestic Subsidiary to guarantee the Indebtedness pursuant to the Guaranty Agreement. In connection with any such guaranty, the Borrower shall, or shall cause such Domestic Subsidiary
to, promptly, but in any event no later than 30 days after the formation or acquisition (or other similar event) of such Domestic Subsidiary, (i) execute and deliver a supplement to the Guaranty Agreement executed by such Domestic Subsidiary, (ii)
pledge all of the Equity Interests of such Domestic Subsidiary (including, without limitation, delivery of original stock certificates evidencing the Equity Interests of such Domestic Subsidiary, together with an appropriate undated 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.

owner of a Foreign Subsidiary, then the Borrower shall, or shall cause such Domestic Subsidiary 
  

 65 

 to, promptly, but in any event no later than 30 days after the date of becoming an owner thereof, (i) 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 (ii) execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent. 
  
 (d) Any Person that must guarantee the Indebtedness in order for the Borrower
to be in compliance with Section 9.04(b)(ii)(C) shall guarantee the Indebtedness pursuant to the Guaranty Agreement. In connection with any such guaranty, the Borrower shall, or shall cause such Person to, promptly, but in any event no later than 30
days after the date required thereby, (A) execute and deliver a supplement to the Guaranty Agreement executed by such Person, and (B) execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be
requested by the Administrative Agent. If at any time such Person is not otherwise required to guarantee the Indebtedness hereunder (whether pursuant to the other provisions of this Section 8.14 or otherwise) or under any other Loan Document, then
upon receipt by the Administrative Agent of evidence satisfactory to it that such Person has been fully and finally released from its guarantee obligations in respect of the Senior Notes, the Senior Subordinated Notes or, if applicable, any
Permitted Additional Notes, as the case may be, such Person shall be released from its guarantee obligations with respect to the Indebtedness and the Administrative Agent shall, at the sole cost and expense of the Borrower, execute such further
documents and do all such further acts so as to reasonably evidence such release. 
  
 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) immediately upon becoming aware of
the occurrence of any ERISA Event or 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 that could reasonably be expected to
have a Material Adverse Effect, 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, the Department of Labor or the PBGC with respect thereto, and (ii) immediately upon receipt thereof,
copies of any notice of the PBGC’s intention to terminate or to have a trustee appointed to administer any Plan that could reasonably be expected to have a Material Adverse Effect. With respect to each Plan (other than a Multiemployer Plan),
the Borrower will, and will cause each Subsidiary and ERISA Affiliate to, (i) satisfy in full and in a timely manner, without incurring any late payment or underpayment charge or penalty that could reasonably be expected to have a Material Adverse
Effect and without giving rise to any lien securing an amount in excess of $20,000,000, all of the contribution and funding requirements of section 412 of the Code (determined without regard to subsections (d), (e), (f) and (k) thereof) and of
section 302 of ERISA (determined without regard to sections 303, 304 and 306 of ERISA), and (ii) pay, or cause to be paid, to the PBGC in a timely manner, without incurring any late payment or underpayment charge or penalty that could reasonably be

all payments made by the Borrower and the Restricted Subsidiaries pursuant to all such leases or lease agreements, including, without limitation, any residual payments at the end of any lease, to exceed $10,000,000 in any period of twelve
consecutive calendar months during the life of such leases. 
  
 Section 9.09 Proceeds of Notes. The Borrower will not permit the proceeds of the Notes to be used for any purpose other than those permitted by Section 7.22. Neither the Borrower nor any Person acting on behalf of the Borrower has

Code, if either of which would have a Material Adverse Effect. 
  

 73 

 (b) terminate, or permit any ERISA Affiliate to terminate, any Plan in a manner, or take any other action

 (c) fail to make, or permit any ERISA Affiliate to fail to make, full payment
when due of all amounts which, under the provisions of any Plan, agreement relating thereto or applicable law, the Borrower, a Subsidiary or any ERISA Affiliate is required to pay as contributions thereto if such failure could reasonably be expected
to have a Material Adverse Effect. 
  
 (d) permit to exist, or
allow any ERISA Affiliate to permit to exist, any accumulated funding deficiency within the meaning of section 302 of ERISA or section 412 of the Code, whether or not waived, with respect to any Plan which exceeds $20,000,000.

on a plan termination basis in accordance with Title IV of ERISA) of such Plan allocable to such benefit liabilities by more than $20,000,000. The term “actuarial present value of the benefit liabilities” shall have the meaning specified

actuarial present value of the benefit liabilities under such Plan exceeds the current value of the assets (computed on a plan termination basis in accordance with Title IV of ERISA) of such Plan allocable to such benefit liabilities by an amount in
excess of $20,000,000. 
  
 (g) incur, or permit any ERISA
Affiliate to incur, a liability to or on account of a Plan under sections 515, 4062, 4063, 4064, 4201 or 4204 of ERISA which could reasonably be expected to have a Material Adverse Effect. 
  
 (h) amend, or permit any ERISA Affiliate to amend, a Plan resulting in an
increase in current liability such that the Borrower, a Subsidiary or any ERISA Affiliate is required to provide security to such Plan under section 401(a)(29) of the Code which could reasonably be expected to have a Material Adverse Effect.

  
 Section 9.11 Sale or Discount of Receivables. Except
for receivables obtained by the Borrower or any Restricted Subsidiary out of the ordinary course of business or the settlement of joint interest billing accounts in the ordinary course of business or discounts granted to settle collection of

“consolidation”); provided that (a) any Restricted Subsidiary may participate in a consolidation with the Borrower (provided that the Borrower shall be the continuing or surviving corporation) or any other Restricted Subsidiary
(provided that if a Guarantor is a party to such transaction, the survivor is such Guarantor or becomes a party to the Guaranty Agreement as a Guarantor) or transfer all or substantially all of its assets to a Guarantor or a Person that becomes a
party to the Guaranty Agreement as a Guarantor, (b) the Borrower or any Restricted Subsidiary may participate in a consolidation (other than as described in clause (a) above) if (i) at the time thereof and immediately after giving effect thereto, no
Default shall occur and be continuing and no Borrowing Base deficiency would result therefrom and (ii) the Borrower or such Restricted Subsidiary, as the case may be, is the surviving entity or the recipient of any such sale, lease or other
disposition of Property, provided that no such consolidation shall have the effect of releasing the Borrower or any Restricted Subsidiary from any of its obligations under this Agreement or any other Loan Document, (c) the liquidation and
dissolution of Subsidiaries shall be permitted if (i) the continued existence and operation of such Subsidiary is no longer in the best interests of the Borrower and its Subsidiaries taken as a whole (as reasonably determined by the board of
directors or any Responsible Officer of the Borrower), (ii) such liquidation and dissolution is not disadvantageous in any material respect to the Lenders, and (iii) at the time thereof and immediately after giving effect thereto, no Default shall

than the fair market value of the Oil and Gas Property (other than in the case of a Casualty Event), interest therein or Restricted Subsidiary subject of such sale or other disposition (as reasonably determined by the board of directors or any
Responsible Officer of the Borrower), (ii) if such sale or other disposition of Oil and Gas Property or Restricted Subsidiary owning Oil and Gas Properties included in the most recently delivered Reserve Report during any period between two
successive Scheduled Redetermination Dates has a fair market value in excess of five percent (5%) of the Borrowing Base then in effect (as reasonably determined by the board of 
  

 75 

 directors of the Borrower), individually or in the aggregate, 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 (iii) if any such sale or other disposition is of a Restricted Subsidiary owning Oil and Gas Properties,
such sale or other disposition shall include all the Equity Interests of such Restricted Subsidiary; (e) the sale of Oil and Gas Properties in connection with tax credit transactions complying with §29 of the Code or any other analogous
provision whether now existing or hereafter enacted, which sale does not result in a reduction in the Borrower’s or its Restricted Subsidiaries’, as the case may be, right to receive the cash flow from such Oil and Gas Properties and which
sale is on terms reasonably acceptable to the Administrative Agent; (f) transfers and other dispositions among the Borrower and the Restricted Subsidiaries subject to the limitations set forth in Section 9.05(g)(iii); and (g) transfers permitted by

lease or exchange of Property or the rendering of any service, with any Affiliate (other than the Guarantors and Wholly-Owned Subsidiaries of the Borrower) unless such transactions are not otherwise prohibited under this Agreement and are upon fair
and reasonable terms no less favorable to it than it would obtain in a comparable arm’s length transaction with a Person not an Affiliate.

different times: (i) terminate the Commitments, and thereupon the Commitments shall terminate immediately, and (ii) declare the Notes and the Loans then outstanding to be due and payable in whole (or in part, in which case any principal not so
declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of the Loans so declared to be due and payable, together with accrued interest thereon and all fees and other obligations of the Borrower
and the Guarantors accrued hereunder and under the Notes and the other Loan Documents (including, without limitation, the payment of cash collateral to secure the LC Exposure as provided in Section 2.08(j)), shall become due and payable immediately,
without presentment, demand, protest, notice of intent to accelerate, notice of acceleration or other notice of any kind, all of which are hereby waived by the Borrower and each Guarantor; and in case of an Event of Default described in Section
10.01(h), Section 10.01(i) or Section 10.01(j), the Commitments shall automatically terminate and the Notes and the principal of the Loans then outstanding, together with accrued interest thereon and all fees and the other obligations of the
Borrower and the Guarantors accrued hereunder and under the Notes and the other Loan Documents (including, without limitation, the payment of cash collateral to secure the LC Exposure as provided in Section 2.08(j)), shall automatically become due
and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower and each Guarantor. 
  
 (b) In the case of the occurrence of an Event of Default, the Administrative Agent and the Lenders will have all other rights and remedies available at
law and equity. 
  
 (c) All proceeds realized from the liquidation

Administrative Agent, Arranger, other Agents and the Lenders; 
  
 (ii) second, pro rata to payment of accrued interest on the Loans;

 ARTICLE XI 
 The Agents 
  
 Section 11.01 Appointment; Powers. Each of the Lenders and each
Issuing Bank hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof
and the other Loan Documents, together with such actions and powers as are reasonably incidental thereto. 
  
 Section 11.02 Duties and Obligations of Administrative Agent. The Administrative Agent shall not have any duties or obligations except those
expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing
(the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any
applicable law; rather, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties), (b) the Administrative Agent shall 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 expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the
failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall be
deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and shall not be responsible for or have any duty to ascertain or inquire into (i) any statement,
warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or under any other Loan Document or in connection herewith or
therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or in any other Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any
other Loan Document or any other agreement, instrument or document, (v) the satisfaction of any condition set forth in ARTICLE VI or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative
Agent, (vi) the existence, value, perfection or priority of any collateral security or the financial or other condition of the Borrower and its Subsidiaries or any other obligor or guarantor, or (vii) any failure by the Borrower or any other Person
(other than itself) to perform any of its obligations hereunder or under any other Loan Document or the performance or observance of any covenants, agreements or other terms or conditions set forth herein or therein. For purposes of determining
compliance with the conditions specified in ARTICLE VI, each Lender shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable
or satisfactory to a Lender unless the Administrative Agent shall have received written notice from such Lender prior to the proposed closing date specifying its objection thereto. 
  

 81 

 Section 11.03 Action by Administrative Agent. The Administrative Agent shall have no duty to take
any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise in writing as directed by the
Majority Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) and in all cases the Administrative Agent shall be fully justified in failing or refusing to act
hereunder or under any other Loan Documents unless it shall (a) receive written instructions from the Majority Lenders or the Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 12.02) specifying the action to be taken and (b) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of taking or continuing to take any such action.
The instructions as aforesaid and any action taken or failure to act pursuant thereto by the Administrative Agent shall be binding on all of the Lenders. If a Default has occurred and is continuing, then the Administrative Agent shall take such
action with respect to such Default as shall be directed by the requisite Lenders in the written instructions (with indemnities) described in this Section 11.03, provided that, unless and until the Administrative Agent shall have received such
directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interests of the Lenders. In no event, however, shall
the Administrative Agent be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, the Loan Documents or applicable law. If a Default has occurred and is continuing, neither
the Syndication Agents nor the Documentation Agents shall have any obligation to perform any act in respect thereof. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the
Majority Lenders or the Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02), and otherwise the Administrative Agent shall not be liable for any action taken or not
taken by it hereunder or under any other Loan Document or under any other document or instrument referred to or provided for herein or therein or in connection herewith or therewith INCLUDING ITS OWN ORDINARY NEGLIGENCE, except for its own gross
negligence or willful misconduct. 
  
 Section 11.04 Reliance by
Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be
genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for
relying thereon and each of the Borrower, the Lenders and each Issuing Bank hereby waives the right to dispute the Administrative Agent’s record of such statement, except in the case of gross negligence or willful misconduct by the
Administrative Agent. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in
accordance with the advice of any such counsel, accountants or experts. The Administrative Agent may deem and treat the payee of any 
  

 82 

 Note as the holder thereof for all purposes hereof unless and until a written notice of the assignment or transfer
thereof permitted hereunder shall have been filed with the Administrative Agent. 
  
 Section 11.05 Subagents. The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The
Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding Sections of this ARTICLE XI shall apply to any
such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as
Administrative Agent. 
  
 Section 11.06 Resignation or Removal
of Agents. Subject to the appointment and acceptance of a successor Administrative Agent as provided in this Section 11.06, the Administrative Agent may resign at any time by notifying the Lenders, each Issuing Bank and the Borrower, and the
Administrative Agent may be removed at any time with or without cause by the Majority Lenders. Upon any such resignation or removal, the Majority Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no
successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation or removal of the retiring Agent, then the retiring Agent may, on behalf
of the Lenders and each Issuing Bank, appoint a successor Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Agent hereunder by a successor, such successor
shall succeed to and become vested with all the rights, powers, 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 
  

 83 

 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 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 Authority of Administrative Agent to Release Collateral and Liens. Each Lender and each 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 each 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 11.10 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Borrower or any of its Subsidiaries, the Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as
herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise: 
  
 (a) to file and prove a claim for the whole amount of the principal and
interest owing and unpaid in respect of the Loans and all other Indebtedness that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent
(including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under
Section 12.03) allowed in such judicial proceeding; and 
  
 (b) to
collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same; 
  
 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to
make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making 
  

 84 

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

 Section 12.02 Waivers; Amendments. 
  
 (a) No failure on the part of the Administrative Agent, any 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, each Issuing Bank and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision
of this Agreement or any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by Section 12.02(b), and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the
Administrative Agent, any Lender or any 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
Commitment or the Maximum Credit Amount of any Lender without the written consent of such Lender, (ii) increase the Borrowing Base without the written consent of all of the Lenders, decrease or maintain the Borrowing Base without the consent of
Super-majority Lenders or modify Section 2.07 without the written consent of all of the Lenders, (iii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, or reduce
any other Indebtedness hereunder or under any other Loan Document, without the written consent of each Lender affected thereby, (iv) postpone the scheduled date of payment or prepayment of the principal amount of any Loan or LC Disbursement, or any
interest thereon, or any fees payable hereunder, or any other Indebtedness hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Termination Date without the written consent
of each Lender affected thereby, (v) change Section 4.01(b) or Section 4.01(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (vi) waive or amend Section 3.04(c), Section

the written consent of each Lender, (vii) release any Guarantor (except as set forth in the Guaranty Agreement, Section 8.14(d) or Section 9.12) or release all or substantially all of the collateral (other than as provided in Section 11.09), without

 86 

 change any of the provisions of this Section 12.02(b) or the definitions of “Super-majority Lenders” or
“Majority Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or under any other Loan Documents or make any determination or grant any consent
hereunder or any other Loan Documents, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, any other Agent or any Issuing Bank
hereunder or under any other Loan Document without the prior written consent of the Administrative Agent, such other Agent or such Issuing Bank, as the case may be. Notwithstanding the foregoing, any supplement to Schedule 7.15 (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, mailing,
courier, telephone and other similar expenses, and the cost of environmental audits and surveys and appraisals, in connection with the syndication of the credit facilities provided for herein, the preparation, negotiation, execution, delivery and
administration (both before and after the execution hereof and including advice of counsel to the Administrative Agent as to the rights and duties of the Administrative Agent and the Lenders with respect thereto) of this Agreement and the other Loan
Documents and any amendments, modifications or waivers of or consents related to the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all costs, expenses, Taxes, assessments and
other charges incurred by any Agent or any Lender in connection with any filing, registration, recording or perfection of any security interest contemplated by this Agreement or any Security Instrument or any other document referred to therein,

incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit. 
  
 (b) THE BORROWER SHALL INDEMNIFY EACH AGENT, THE ARRANGER, EACH ISSUING BANK 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 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 
  

 87 

 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

LIMITATION, (A) ANY REFUSAL BY ANY ISSUING BANK TO HONOR A DEMAND FOR PAYMENT UNDER A LETTER OF CREDIT ISSUED BY SUCH ISSUING BANK IF THE DOCUMENTS PRESENTED IN CONNECTION WITH SUCH DEMAND DO NOT STRICTLY COMPLY WITH THE TERMS OF SUCH LETTER OF
CREDIT, OR (B) THE PAYMENT OF A DRAWING UNDER ANY LETTER OF CREDIT NOTWITHSTANDING THE NON-COMPLIANCE, NON-DELIVERY OR OTHER IMPROPER PRESENTATION OF THE DOCUMENTS PRESENTED IN CONNECTION THEREWITH, (v) ANY OTHER ASPECT 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 SECURITY INSTRUMENTS, (viii) ANY
ENVIRONMENTAL LAW APPLICABLE TO THE BORROWER OR ANY SUBSIDIARY OR ANY OF THEIR PROPERTIES, INCLUDING WITHOUT LIMITATION, THE PRESENCE, GENERATION, STORAGE, RELEASE, THREATENED RELEASE, USE, TRANSPORT, DISPOSAL, ARRANGEMENT OF DISPOSAL OR TREATMENT
OF OIL, OIL AND GAS WASTES, SOLID WASTES OR HAZARDOUS SUBSTANCES ON ANY OF THEIR PROPERTIES, (ix) THE BREACH OR NON-COMPLIANCE BY THE BORROWER OR ANY SUBSIDIARY WITH ANY ENVIRONMENTAL LAW APPLICABLE TO THE BORROWER OR ANY SUBSIDIARY, (x) THE PAST
OWNERSHIP BY THE BORROWER OR ANY SUBSIDIARY OF ANY OF THEIR PROPERTIES OR PAST ACTIVITY ON ANY OF THEIR PROPERTIES WHICH, THOUGH LAWFUL AND FULLY PERMISSIBLE AT THE TIME, COULD RESULT IN PRESENT 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 
  

 88 

 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

JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILFUL MISCONDUCT OF SUCH INDEMNITEE. 
  
 (c) To the extent that the Borrower fails to pay any amount required to be paid by it to any Agent, the Arranger or any Issuing Bank under Section
12.03(a) or (b), each Lender severally agrees to pay to such Agent, the Arranger or such Issuing Bank, as the case may be, such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity
payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against such Agent, the Arranger or such 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

 (e) All amounts due under this Section 12.03 shall be payable not later than
10 days after written demand therefor. 
  
 (f) Notwithstanding any
other provisions of this Section 12.03, 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 12.04 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 any Issuing Bank that issues any Letter of Credit), except that (i) the 
  

 89 

 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

 (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. 

 
 (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 
  

 90 

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

 91 

 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 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. 
  
 Section 12.05 Survival; Revival; Reinstatement. 
  
 (a) All covenants, agreements, representations and warranties made by the
Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the
execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, any 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 
  

 92 

 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 (other than the Letters of Credit and the Letter of Credit Agreements) represent the 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 
  

 93 

 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 SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

  
 (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN
DOCUMENTS SHALL BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PARTY HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT

OBTAINING JURISDICTION OVER ANOTHER PARTY IN ANY COURT OTHERWISE HAVING JURISDICTION. 
  
 (c) THE BORROWER HEREBY IRREVOCABLY DESIGNATES, APPOINTS AND EMPOWERS AND HEREBY CONFERS AN IRREVOCABLE SPECIAL POWER, AMPLE AND SUFFICIENT, TO CT CORPORATION SYSTEM, WITH OFFICES ON THE DATE HEREOF AT 111 EIGHTH
AVENUE, THIRTEENTH FLOOR, NEW YORK, NEW YORK, 10011 AS ITS DESIGNEE, APPOINTEE AND AGENT WITH RESPECT TO ANY SUCH ACTION OR PROCEEDING IN NEW YORK TO RECEIVE, ACCEPT AND ACKNOWLEDGE FOR AND ON ITS BEHALF, AND IN RESPECT OF ITS PROPERTY, SERVICE OF
ANY AND ALL LEGAL PROCESS, SUMMONS, NOTICES AND DOCUMENTS WHICH MAY BE SERVED IN ANY SUCH PROCEEDING AND AGREES THAT THE FAILURE OF SUCH AGENT TO GIVE ANY ADVICE OF ANY SUCH SERVICE OF PROCESS TO THE BORROWER SHALL NOT IMPAIR OR AFFECT THE VALIDITY
OF SUCH SERVICE OR OF ANY CLAIM BASED THEREON. IF FOR ANY REASON SUCH DESIGNEE, APPOINTEE AND AGENT SHALL CEASE TO BE AVAILABLE TO ACT AS SUCH, THE BORROWER AGREES TO DESIGNATE A NEW DESIGNEE, APPOINTEE AND AGENT IN NEW YORK CITY REASONABLY
SATISFACTORY TO THE ADMINISTRATIVE AGENT ON THE TERMS AND FOR THE PURPOSES OF THIS PROVISION. EACH PARTY 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 IT AT THE ADDRESS SPECIFIED IN SECTION 12.01 OR SUCH OTHER ADDRESS AS IS SPECIFIED PURSUANT TO

AGREEMENT, THE LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 12.09. 
  
 Section 12.10 Headings. Article and Section headings and the Table of Contents used herein are for convenience of
reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement. 
  
 Section 12.11 Confidentiality. Each of the Administrative Agent, each 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 (provided that such Person agrees in writing to be bound by the provisions of this Section 12.11) or (ii) any actual or
prospective counterparty (or its advisors) to any Swap Agreement relating to the Borrower and its obligations (provided that such Person agrees in writing to be bound by the provisions of this Section 12.11), (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, any Issuing 
  

 95 

 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, any Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Borrower or a Restricted Subsidiary; provided that, in the case of information received from the Borrower or any Restricted Subsidiary after
the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section 12.11 shall be considered to have complied with its
obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information. 
  
 Section 12.12 Interest Rate Limitation. It is the intention of the
parties hereto that each Lender shall conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be usurious as to any Lender under laws applicable to it (including the laws of the United States of
America and the State of New York or any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any of the
Loan Documents or any agreement entered into in connection with or as security for the Notes, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under law applicable to any Lender that is contracted for,
taken, reserved, charged or received by such Lender under any of the Loan Documents or agreements or otherwise in connection with the Notes shall under no circumstances exceed the maximum amount allowed by such applicable law, and any excess shall
be canceled automatically and if theretofore paid shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full,
refunded by such Lender to the Borrower); and (ii) in the event that the maturity of the Notes is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of
any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Lender may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in
this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent
that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder
shall, to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated and spread throughout the actual full term of the Loans evidenced by the Notes until payment in full so that the rate or amount of interest on account
of any Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at any time and from time to time (i) the amount of interest payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to
such Lender pursuant to this Section 12.12 and (ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to such Lender would be less than the amount of interest payable to such Lender 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 
  

 96 

 amount of interest payable to such Lender shall equal the total amount of interest which would have been payable to such
Lender if the total amount of interest had been computed without giving effect to this Section 12.12. 
  
 Section 12.13 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS, CONDITIONS
AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN
ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND
RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE
BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.” 
  
 Section 12.14 Specified Senior Indebtedness. The Parties acknowledge and agree that the Indebtedness hereunder is specifically designated
“Designated Senior Indebtedness” as required by the Senior Subordinated Indenture pursuant to which the Senior Subordinated Notes have been issued. 
  
 Section 12.15 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 any Lender or any Affiliate of a Lender that is counterparty to any Swap Agreement with the Borrower or any of its Subsidiaries (including
any Swap Agreement between such Persons in existence prior to the date hereof) 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; provided that such benefits
shall cease to extend to and be available to any such Lender or Affiliate in respect of obligations under such Swap Agreements if such Person or its Affiliate, as the case may be, ceases to be Lender. For the avoidance of doubt, a Person ceases to
be a Lender hereunder if (a) pursuant to an assignment, such Person ceases to have any Commitment, Loans and LC Exposure hereunder or (b) the Commitments of all of the Lenders hereunder have been terminated and all principal, interest and other
amounts outstanding under this Agreement have been paid in full in cash (whether as a result of repayment at maturity, prepayment in connection with the refinancing of this Agreement or otherwise). 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. 
  

 97 

 Section 12.16 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 12.17 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.

 EXECUTIVES’ LONG-TERM RETENTION 
 & DEFERRED COMPENSATION

  
  
 ARTICLE I.  
 PURPOSES AND DEFINITIONS 
  

	1.1	Purpose 

  
 Plains Exploration & Production Company (the “Company”), hereby establishes the Plains Exploration & Production Company
Executives’ Long-Term Retention & Deferred Compensation Arrangement (the “Plan”) for the purpose of providing certain management and highly compensated employees (“Executives”) of the Company the opportunity to
defer all or a portion of their cash or equity compensation, to better align the interests of the Executives with those of the Company’s shareholders and to attract and retain talented individuals. This Plan is intended to be an unfunded
nonqualified plan of deferred compensation that complies with section 409A of the Internal Revenue Code of 1986 as amended (the “Code”) and a “top hat” pension plan within the meaning of Department of Labor regulations
promulgated pursuant to the Employee Retirement Income Security Act of 1976 as amended.

 Subject to the provisions hereof, the Committee shall have full and exclusive power and authority to administer this Plan and to take all actions that are
specifically contemplated hereby or are necessary or appropriate in connection with the administration hereof. The Committee shall also have full and exclusive power to interpret this Plan and to adopt such rules, regulations, and guidelines for
carrying out this Plan as it may deem necessary or proper, all of which powers shall be exercised in the best interests of the Company and in keeping with the objectives of this Plan. The Committee may, in its discretion, determine the eligibility
of individuals to participate herein, determine the amount of Compensation a Participant may elect to defer, or waive any restriction or other provision of this Plan; provided, however, that the Committee shall not waive any restriction or other
provision of this Plan or take any other action that would cause any benefits provided to a Participant hereunder to be deemed “derivative securities” within the meaning of § 16 of the Exchange Act or the rules and regulations
promulgated thereunder (including, but not limited to, Rule 16a-1(c) or any successor rule) or would result in adverse tax consequences to Participant under section 409A of the Code; provided further, however, that no member of the Committee may
participate in or take any action with respect to any decision regarding his or her own Compensation. The Committee may correct any defect or supply any omission or reconcile any inconsistency in this Plan in the manner and to the extent the
Committee deems necessary or desirable to carry it into effect.

 ARTICLE III.  
 DEFERRALS 
  

	3.1	Establishment of Accounts 

  
 The Company shall set up an appropriate record (the “Account”), which will from time to time reflect the name of each Participant and the
amounts credited to such Participant pursuant to § 3.2. 
  

	3.2	Equity Compensation Deferral 

  
 A Participant may elect to defer receipt of all or part of any Equity Compensation payable to the Participant. Except as otherwise provided in
Section 3.3 below, to be effective, a Deferral Election must be made by the Participant in the calendar year prior to the year in which the services giving rise to the Equity Compensation are performed. The Election Effective Date shall be the
first day of the calendar year occurring after the Deferral Election. Subject to the provisions of Section 3.11 below, if a Participant makes a Deferral Election, a number of Restricted Stock Units (rounded up to the nearest whole number)
having a Fair Market Value equal to the dollar amount of Equity Compensation the Participant elects to forgo shall be credited to the Participant’s Account as of the date that such Equity Compensation would be paid to Participant but for the
Deferral Election. Each Deferral Election shall be irrevocable as of the Election Effective Date and shall be effective for a period of one calendar year beginning on the Election Effective Date. Deferred Compensation attributable to an Equity
Compensation Deferral Election shall be Vested according to the terms of the Equity Compensation grant without regard to the Deferral Election. 
  

	3.3	Elections of First-Year Participants 

  
 In the case of the first year in which a Participant becomes eligible to participate in the Plan, a Deferral Election may be made with respect to services
to be performed subsequent to the election, provided that such election is made within 30 days after the date the Participant first becomes eligible to participate. In such case, the Election Effective Date shall be the first date that services are
performed after the Election Date. 
  

 4 

	3.4	Deferral Elections 

  
 Each Deferral Election made by a Participant under the Plan (i) shall take the form of a written document (provided by the Company) signed by the
Participant and filed with the Company, (ii) shall designate the calendar year for which the deferral is made and the period of deferral, and (iii) cannot be revoked or modified if either (a) the proposed revocation or modification
applies to amounts deferred with respect to a calendar year which has already commenced at the time such revocation or modification is proposed to be effected, or (b) the Committee determines in its sole discretion that the proposed revocation
or modification could cause any benefits provided to a Participant hereunder to be treated as “derivative securities” within the meaning of § 16 of the Exchange Act or the rules and regulations promulgated thereunder (including,
but not limited to, Rule 16a-1(c) or any successor rule) or could result in adverse tax consequences to the Participant under section 409A of the Code. Any election to change a Deferral Election (including an election to change a Payment Date) shall
be subject to the consent of the Committee and the terms of the Plan. 
  

	3.5	Dividends 

  
 As of each date that dividends are paid with respect to Common Stock, a Participant who has any outstanding Restricted Stock Units credited to his or her
Account shall have an additional amount credited to his or her Account equal to the number of Restricted Stock Units (rounded up to the nearest whole number) having a Fair Market Value equal to the dollar amount of dividends paid per share of Common
Stock multiplied by the number of Restricted Stock Units credited to the Participant’s Account as of the payment date of such dividend. 
  

	3.6	Adjustments 

  

	 	(a)	Exercise of Corporate Powers. The existence of this Plan and any outstanding Restricted Stock Units credited hereunder shall not affect in any manner the right or
power of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the capital stock of the Company or its business or any merger or consolidation of the Company, or any issue
of bonds, debentures, preferred or prior preference stock (whether or not such issue is prior to, on a parity with or junior to the Common Stock) or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its
assets or business, or any other corporate act or proceeding of any kind, whether or not of a character similar to that of the acts or proceedings enumerated above. 

  

	 	(b)	 Recapitalizations, Reorganizations and Other Activities. In the event of any subdivision or consolidation of outstanding shares of Common Stock,
declaration of a dividend payable in shares of Common Stock or other stock split, then (i) the number of Restricted Stock Units and (ii) the appropriate Fair Market Value and other price determinations for such Restricted Stock Units shall
each be proportionately adjusted by the Board to reflect such transaction. In the event of any other recapitalization or capital reorganization of the Company, any consolidation or merger of the Company with another corporation or entity, the

  

 5 

	 	 
adoption by the Company of any plan of exchange affecting the Common Stock or any distribution to holders of Common Stock of securities or property (other
than normal cash dividends or dividends payable in Common Stock), the Board shall make appropriate adjustments to (i) the number of Restricted Stock Units and (ii) the appropriate Fair Market Value and other price determinations for such
Restricted Stock Units to give effect to such transaction; provided that such adjustments shall only be such as are necessary to preserve, without increasing, the value of such units. In the event of a corporate merger, consolidation, acquisition of
property or stock, separation, reorganization or liquidation, the Board shall be authorized to issue or assume units by means of substitution of new units, as appropriate, for previously issued units or an assumption of previously issued units as
part of such adjustment. 

  

	3.7	Payment Date 

  

	 	(a)	Payment Date. A Participant may elect that payment of Deferred Compensation under the Plan be made on a date or pursuant to a fixed schedule specified on the Deferral
Election form (the “Payment Date”) provided by the Committee, provided that such date does not occur before the date such Deferred Compensation would be paid or Vested absent such deferral. In the event of the death or Disability of an
Executive prior to the date specified on the Deferral Election form, such Executive’s date of death or Disability shall be his or her Payment Date. If Participant does not make a payment election at the time of the Deferral Election, his or her
Payment Date shall be the earliest of: 

  

	 	(i)	the tenth anniversary of the Election Effective Date; 

  

	 	(ii)	death or Disability of the Participant; 

  

	 	(iii)	six months (or such shorter period as may be permitted pursuant to regulations or interpretations of Section 409A of the Code) following the date of Executive’s separation
from service; or 

  

	 	(iv)	occurrence of an unforeseeable emergency as defined in Section 409A of the Code. 

  

	 	(b)	Changes to Payment Date. After the Election Effective Date a Participant who has a right to receive Deferred Compensation pursuant to this Plan may elect to defer
payment beyond the Payment Date, provided that each of the following conditions is met: 

  

	 	(i)	such election may not take effect until at least twelve (12) months after the date on which the election is made; 

  

 6 

	 	(ii)	except in the case of death or Disability the first payment with respect to which such election is made must be deferred for a period of at least 5 years from the date such payment
would otherwise have been made, and 

  

	 	(iii)	in the case of a payment to be made pursuant to a fixed schedule or on a fixed date, any election may not be made less than twelve (12) months prior to the date of the first
scheduled Payment Date. 

  

	3.8	Payment/Withholding 

  
 As of the Payment Date, the aggregate Fair Market Value of the Restricted Stock Units then credited to a Participant’s Account shall be calculated.
Payment to a Participant of his of her Account (subject to any applicable tax or withholding required under state, federal or local law) shall be made in cash or Common Stock, at the discretion of the Committee as soon as administratively feasible
following the Payment Date. The Company shall deduct and withhold from the Account or any other amounts due to Participant any applicable employment or income tax or withholding required to be paid or withheld with respect to Participant’s
Compensation. 
  

	3.9	Death Prior to Payment 

  
 In the event that a Participant dies prior to payment pursuant to the Plan, any such unpaid amounts, shall be paid to the Participant’s designated
Beneficiary in a lump sum within sixty (60) days following the Company’s notification of the Participant’s death. If no Beneficiary has been designated, such payment shall be made to the Participant’s estate. A beneficiary
designation, or revocation of a prior beneficiary designation, shall be effective only if it is made in writing on a form provided by the Company, signed by the Participant and received by the Committee. 
  

	3.10	Limitation on Restricted Stock Units Credited to Accounts and Hypothetical Investment 

  
 Restricted Stock Units shall be credited to a Participant’s Account only if and to the extent that the Company has
adopted a plan of equity compensation that has been approved by shareholders which permits the granting of Restricted Stock Units to Participant. In the event that Restricted Stock Units may not be credited to Participant’s Account the
Committee shall denominate the portion of Participant’s Account that is not in Restricted Stock Units in US dollars. In addition, notwithstanding anything in the Plan to the contrary, the Committee, in its sole discretion may permit the
Participant to elect to denominate all or part of his or her Account in US dollars in lieu of Restricted Stock Units. In the event that any portion of a Participant’s Account is denominated in US dollars, the Participant shall be allowed to
select from among various hypothetical investment benchmarks selected by the Committee, which shall include, but not be limited to, common stock of the Company. If the Participant does not select from among the hypothetical investment benchmarks
made available by Committee, the Participant’s Account shall be credited with simple interest at the rate of six (6%) per annum. The Participant’s Account shall be adjusted from time to time, but not less often than semi-annually for
any earnings, gains and losses allocable to such Account from such hypothetical investment benchmarks or interest. Notwithstanding the foregoing, the terms of this Plan place no 

  

 7 

 
obligation upon the Company to set aside or to invest or to continue to invest any funds or portion of the Account in any specific asset, to liquidate any
particular investment, or to apply in any specific manner the proceeds from the sale, liquidation, or maturity of any particular investment. The Company assumes no risk of any decrease in the value of any investment designations made by Participant
with respect to the hypothetical investment benchmarks. The Company’s sole obligations are to maintain the Participant’s Account and make payments to the Participant as herein provided. 
  
  
 ARTICLE IV.  
 LONG-TERM RETENTION COMPENSATION 
  

	4.1	Retention Awards 

  
 Each Participant shall be eligible to receive Long-Term Retention Compensation in an amount and according to the terms and conditions determined by the
Committee and set forth in an Agreement. Such Long-Term Retention Compensation shall be in the form of additional Restricted Stock Units to be added to Participant’s Account according to the terms and conditions determined by the Committee and
set forth in an Agreement. Such Agreement shall specify the Payment Date and any provisions relating to Deferral Elections or Vesting not inconsistent with the Plan. Except as otherwise provided in the Agreement, Participant may elect to change the
Payment Date with respect to Long-Term Retention Compensation according to the requirements set forth in Section 3.7 (b) of the Plan. 
  
  
 ARTICLE V.  
 MISCELLANEOUS 
  

	5.1	Unfunded Plan 

  
 Nothing contained herein shall be deemed to create a trust of any kind or create any fiduciary relationship. This Plan shall be unfunded. Any funds
invested hereunder shall continue for all purposes to be part of the general funds of the Company. To the extent that a Participant acquires a right to receive payments from the Company under the Plan, such right shall not be greater than the right
of any unsecured general creditor of the Company and such right shall be an unsecured claim against the general assets of the Company. Although bookkeeping accounts may be established with respect to Participants who are entitled to rights under
this Plan, any such accounts shall be used merely as a bookkeeping convenience. The Company shall not be required to segregate any assets that may at any time be represented by cash or rights thereto, nor shall this Plan be construed as providing
for such segregation, nor shall the Company, the Board or the Committee be deemed to be a trustee of any cash or rights thereto to be granted under this Plan. Any liability or obligation of the Company to any Participant with respect to cash or
rights thereto under this Plan shall be based solely upon any contractual obligations that may be created by this Plan, and no such liability or obligation of the Company shall be deemed to be secured by any pledge or other encumbrance on any
property of the 

  

 8 

 
Company. Neither the Company nor the Board nor the Committee shall be required to give any security or bond for the performance of any obligation that may be
created by this Plan. 
  

	5.2	Title to Funds Remains with Company 

  
 Amounts credited to each Participant’s Stock Unit Account shall not be specifically set aside or otherwise segregated, but will be combined with
corporate assets. Title to such finds will remain with the Company and the Company’s only obligation will be to make timely payments to Participants in accordance with the Plan. 
  

	5.3	Statement of Account 

  
 A statement will be furnished to each Participant not less often than annually and shall reflect the balance and Fair Market Value of the
Participant’s Account as of the preceding December 31. 
  

	5.4	Assignability 

  
 Except as otherwise provided herein, no right to receive payment hereunder shall be transferable or assignable by a Participant except by will or the laws
of descent and distribution or pursuant to a qualified domestic relations order as defined by the Code or Title I of the Employee Retirement Income Security Act of 1974, as amended, or the rules thereunder. Any attempted assignment of any benefit
under this Plan in violation of this § 5.4 shall be null and void. 
  

	5.5	Amendment, Modification, Suspension, or Termination 

  
 The Board may amend, modify, suspend, or terminate this Plan for the purpose of meeting or addressing any changes in legal requirements or for any other
purpose permitted by law, except that no amendment, modification, or termination shall, without the consent of the Participant, impair the rights of any Participant to the balance in such Participant’s Stock Unit Account as of the date of such
amendment, modification, or termination. The Board may at any time and from time to time delegate to the Committee any or all of its authority under this § 5.5. 
  

	5.6	Payments to Minors and Incompetents 

  
 Should the Participant become incompetent or should the Participant designate a Beneficiary who is a minor or incompetent, the Company shall be authorized
to pay such funds to a parent or guardian of such minor or incompetent, or directly to such minor or incompetent, whichever manner the Committee shall determine in its sole discretion. 
  

 9 

	5.7	Governing Law 

  
 This Plan and all determinations made and actions taken pursuant hereto, to the extent not otherwise governed by mandatory provisions of the Code or the
securities laws of the United States, shall be governed by and construed in accordance with the laws of the State of Texas.
