In the case of a request for an amendment of any outstanding Letter of Credit, such L/C Application shall specify in form and detail satisfactory to such Issuing Lender (A) the Letter of Credit to be amended; (B) the proposed date of amendment thereof (which shall be a Business Day); (C) the nature of the proposed amendment; and (D) such other matters as such Issuing Lender may require. Additionally, the Borrower shall furnish to such Issuing Lender and the Administrative Agent such other documents and information pertaining to such requested Letter of Credit issuance or amendment as such Issuing Lender or the Administrative Agent may require.

(b) Promptly after receipt of any L/C Application, such Issuing Lender will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has received a copy of such L/C Application from the Borrower and, if not, such Issuing Lender will provide the Administrative Agent with a copy thereof. Administrative Agent will promptly notify each Lender of the receipt of such L/C Application. Unless such Issuing Lender has received written notice from any Lender, the Administrative Agent or any Loan Party, at least one Business Day prior to the requested date of issuance or amendment of the applicable Letter of Credit, that one or more applicable conditions contained in Article 5 shall not then be satisfied, then, subject to the terms and conditions hereof, such Issuing Lender shall, on the requested date, issue a Letter of Credit for the account of the Borrower (or the Company or a Subsidiary Guarantor, as applicable) or enter into the applicable amendment, as the case may be, in each case in accordance with such Issuing Lender’s usual and customary business practices. Immediately upon the issuance of each Letter of Credit in accordance with the terms hereof, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from such Issuing Lender a risk participation in such Letter of Credit in an amount equal to the product of such Lender’s Aggregate Exposure Percentage times the amount of such Letter of Credit.

(c) Promptly after its delivery of any Letter of Credit or any amendment to a Letter of Credit to an advising bank with respect thereto or to the beneficiary thereof, such Issuing Lender will also deliver to the Borrower and the Administrative Agent a true and complete copy of such Letter of Credit or amendment.

(d) In the event of any conflict between the terms hereof and the terms of any L/C Application, the terms hereof shall control.

Section 2.7. Drawings and Reimbursements; Funding of Participations.

(a) Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the Issuing Lender shall notify the Borrower and the Administrative Agent thereof. Not later than 11:00 A.M. on the date of any payment by such Issuing Lender under a Letter of Credit (each such date, an “Honor Date”), the Borrower shall reimburse such Issuing Lender through the Administrative Agent in an amount equal to the amount of such drawing. If the Borrower fails to so reimburse such Issuing Lender by such time, the Administrative Agent shall promptly notify each Lender of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed Amount”), and the amount of such Lender’s Revolving Percentage thereof. In such event, the Borrower shall be deemed to have requested a borrowing of Base Rate Revolving Loans to be disbursed on the Honor Date in an amount equal to the Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.2 for the principal amount of Base Rate Revolving Loans, but subject to the amount of the unutilized portion of the Revolving Commitments and the conditions set forth in Section 5.2. Any notice given by such Issuing Lender or the Administrative Agent pursuant to this Section 2.7(a) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(b) Each Lender shall upon any notice pursuant to Section 2.7(a) make funds available to the Administrative Agent for the account of such Issuing Lender at the Administrative Agent’s office in an amount equal to its Revolving Percentage of the Unreimbursed Amount not later than 1:00 p.m., Los Angeles, California time, on the Business Day specified in such notice by the Administrative Agent, whereupon, subject to the provisions of Section 2.7(c), each Lender that so makes funds available shall be deemed to have made a Base Rate Revolving Loan to the Borrower in such amount. The Administrative Agent shall remit the funds so received to such Issuing Lender.

(c) With respect to any Unreimbursed Amount that is not fully refinanced by a borrowing of Base Rate Revolving Loans because the conditions set forth in Section 5.2 cannot be satisfied or for any other reason, the Borrower shall be deemed to have incurred from such Issuing Lender an L/C Borrowing in the amount of the Unreimbursed Amount that is not so refinanced, which L/C Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the rate determined in accordance with Section 3.5(c). In such event, each Lender’s payment to the Administrative Agent for the account of such Issuing Lender pursuant to Section 2.7(b) shall be deemed payment in respect of its participation in such L/C Borrowing and shall constitute an L/C Advance from such Lender in satisfaction of its participation obligation under this Section 2.7.

(d) Until each Lender funds its Revolving Loan or L/C Advance pursuant to this Section 2.7 to reimburse such Issuing Lender for any amount drawn under any Letter of Credit, interest in respect of such Lender’s Revolving Percentage of such amount shall be solely for the account of such Issuing Lender.

(e) Each Lender’s obligation to make Revolving Loans or L/C Advances to reimburse such Issuing Lender for amounts drawn under Letters of Credit, as contemplated by this Section 2.7, shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against such Issuing Lender, the Borrower or any other Person for any reason whatsoever; (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Lender’s obligation to make Revolving Loans pursuant to this Section 2.7 is subject to the conditions set forth in Section 5.2. No such making of an L/C Advance shall relieve or otherwise impair the obligation of the Borrower to reimburse such Issuing Lender for the amount of any payment made by such Issuing Lender under any Letter of Credit, together with interest as provided herein.

(f) If any Lender fails to make available to the Administrative Agent for the account of such Issuing Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.7 by the time specified in Section 2.7(b), such Issuing Lender shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to such Issuing Lender at a rate per annum equal to the greater of the Federal Funds Effective Rate and a rate determined by such Issuing Lender in accordance with banking industry rules on interbank compensation. A certificate of such Issuing Lender submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this Section 2.7(f) shall be conclusive absent manifest error.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(g) Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, the Company or any other Group Member, the Borrower shall be obligated to reimburse the Issuing Lender hereunder for any and all drawings under such Letter of Credit. The Borrower hereby acknowledges that the issuance of Letters of Credit for the account of the Company or any other Group Member inures to the benefit of the Borrower, and that the Borrower’s business derives substantial benefits from the businesses of the Company and the other Group Members.

Section 2.8. Repayment of Participations.

(a) At any time after such Issuing Lender has made a payment under any Letter of Credit and has received from any Lender such Lender’s L/C Advance in respect of such payment in accordance with Section 2.7, if the Administrative Agent receives for the account of such Issuing Lender any payment in respect of the related Unreimbursed Amount or interest thereon (whether directly from the Borrower or otherwise, including proceeds of Cash Collateral applied thereto by the Administrative Agent), the Administrative Agent will distribute to such Lender its Revolving Percentage thereof (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s L/C Advance was outstanding) in the same funds as those received by the Administrative Agent.

(b) If any payment received by the Administrative Agent for the account of such Issuing Lender pursuant to Section 2.7(a) is required to be returned under any of the circumstances described in Section 10.7 (including pursuant to any settlement entered into by such Issuing Lender in its discretion), each Lender shall pay to the Administrative Agent for the account of such Issuing Lender its Revolving Percentage thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to the Federal Funds Effective Rate from time to time in effect. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement.

Section 2.9. Obligations Absolute. The obligation of the Borrower to reimburse such Issuing Lender for each drawing under each Letter of Credit and to repay each L/C Borrowing shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following:

(a) any lack of validity or enforceability of such Letter of Credit, this Agreement, or any other Loan Document;


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(b) the existence of any claim, counterclaim, setoff, defense or other right that the Borrower or any Subsidiary may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), such Issuing Lender or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction;

(c) any draft, demand, certificate or other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of Credit;

(d) any payment by such Issuing Lender under such Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or any payment made by such Issuing Lender under such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of such Letter of Credit, including any arising in connection with any proceeding under any Debtor Relief Law; or

(e) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Borrower or any Subsidiary.

The Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto that is delivered to it and, in the event of any claim of noncompliance with the Borrower’s instructions or other irregularity, the Borrower will immediately notify such Issuing Lender. The Borrower shall be conclusively deemed to have waived any such claim against such Issuing Lender and its correspondents unless such notice is given as aforesaid.

Section 2.10. Role of each Issuing Lender. Each Lender and the Borrower agree that, in paying any drawing under a Letter of Credit, such Issuing Lender shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. None of such Issuing Lender, the Administrative Agent, any of their respective Related Parties nor any correspondent, participant or assignee of such Issuing Lender shall be liable to any Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the Majority Lenders, as applicable; (ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or Issuer Document. The Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided, however, that this assumption is not intended to, and shall not, preclude the Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of such Issuing Lender, the Administrative Agent, any of their respective Related Parties nor any correspondent, participant or assignee of such Issuing Lender shall be liable or responsible for any of the matters described in clauses (a) through (e) of Section 2.9; provided, however, that anything in such clauses to the contrary notwithstanding, the Borrower may have a claim against such Issuing Lender, and such Issuing Lender may be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by the Borrower which the Borrower proves were caused by such Issuing Lender’s willful misconduct or gross negligence or such Issuing Lender’s willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In furtherance and not in limitation of the foregoing, such Issuing Lender may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and such Issuing Lender shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason. If any draft shall be presented for payment under any Letter of Credit, the Issuing Lender shall promptly notify the Borrower of the date and amount thereof.

Section 2.11. Cash Collateral.

(a) Requirement. Upon the request of an Issuing Lender, (i) if such Issuing Lender has honored any full or partial drawing request under any Letter of Credit and such drawing has resulted in an L/C Borrowing, or (ii) if, as of the L/C Expiration Date, any L/C Obligation for any reason remains outstanding, the Borrower shall, in each case, immediately Cash Collateralize the then outstanding amount of all L/C Obligations. If, after the making of all mandatory prepayments required under Section 3.2, the outstanding L/C Obligations will exceed the Borrowing Base, then in addition to prepayment of the entire principal balance of the Loans required under Section 3.2, the Borrower shall immediately Cash Collateralize the then outstanding LC Obligations in an amount equal to such excess. At any time that there shall exist a Defaulting Lender, immediately upon the request of the Administrative Agent or Issuing Lender, the Borrower shall deliver Cash Collateral to the Administrative Agent in an amount sufficient to cover all Fronting Exposure (after giving effect to Section 2.18(b) and any Cash Collateral provided by the Defaulting Lender).

(b) Grant of Security Interest. All Cash Collateral (other than credit support not constituting funds subject to deposit) shall be maintained in blocked, non-interest bearing deposit accounts at the Administrative Agent. The Borrower, and to the extent provided by any Lender, such Lender, hereby grants to (and subjects to the control of) the Administrative Agent, for the benefit of the Administrative Agent, Issuing Lenders and the Lenders, and agrees to maintain, a first priority security interest in all such cash, deposit accounts and all balances therein, and all other property so provided as collateral pursuant hereto, and in all proceeds of the foregoing, all as security for the obligations to which such Cash Collateral may be applied pursuant to Section 2.11(c). If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent as herein provided, or that the total amount of such Cash Collateral is less than the applicable Fronting Exposure and other obligations secured thereby, the Borrower or the relevant Defaulting Lender will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(c) Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under any of this Section 2.11 or Section 2.5(f) or Article 8 in respect of Letters of Credit shall be held and applied to the satisfaction of the specific L/C Obligations, obligations to fund participations therein (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may be provided for herein.

(d) Release. Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure or other obligations shall be released promptly following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Lender (or, as appropriate, its assignee following compliance with Section 10.6 or (ii) the Administrative Agent’s good faith determination that there exists excess Cash Collateral; provided, however, (x) that Cash Collateral furnished by or on behalf of a Group Member shall not be released during the continuance of a Default or Event of Default (and following application as provided in this Section 2.11 may be otherwise applied in accordance with Article 8), and (y) the Person providing Cash Collateral and Issuing Lender or Swing Line Lender, as applicable, may agree that Cash Collateral shall not be released but instead held to support future anticipated Fronting Exposure or other obligations.

Section 2.12. Applicability of ISP and UCP. Unless otherwise expressly agreed by such Issuing Lender and the Borrower when a Letter of Credit is issued (including any such agreement applicable to an Existing Letter of Credit), (i) the rules of the ISP shall apply to each standby Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber of Commerce at the time of issuance shall apply to each commercial Letter of Credit.

Section 2.13. Letter of Credit Fees.

(a) The Borrower shall pay to the Administrative Agent for the account of each Lender in accordance with its Revolving Percentage a Letter of Credit fee (the “Letter of Credit Fee”) (i) for each commercial Letter of Credit equal to the Applicable Margin then in effect with respect to Eurodollar Loans per annum times the daily amount available to be drawn under such Letter of Credit, and (ii) for each standby Letter of Credit equal to the Applicable Margin then in effect with respect to Eurodollar Loans per annum times the daily amount available to be drawn under such Letter of Credit. For purposes of computing the daily amount available to be drawn under any Letter of Credit, the amount of such Letter of Credit shall be determined in accordance with Section 1.3. Letter of Credit Fees shall be (i) computed on a quarterly basis in arrears and (ii) due and payable on the L/C Fee Payment Date, commencing with the first such date to occur after the issuance of such Letter of Credit, on the L/C Expiration Date and thereafter on demand. If there is any change in the Applicable Margin in effect with respect to Eurodollar Loans during any quarter, the daily amount available to be drawn under each standby Letter of Credit shall be computed and multiplied by the Applicable Margin in effect with respect to Eurodollar Loans separately for each period during such quarter that such Applicable Margin was in effect. Notwithstanding anything to the contrary contained herein, upon the request of the Majority Lenders, while any Event of Default exists, all Letter of Credit Fees shall accrue at the rate determined in accordance with Section 3.5(c). Notwithstanding anything to the contrary contained herein, any Letter of Credit Fees otherwise payable for the account of a Defaulting Lender with respect to any Letter of Credit as to which such Defaulting Lender has not provided Cash Collateral satisfactory to the Issuing Lender shall be payable, to the maximum extent permitted by applicable Law, to the other Lenders in accordance with the upward adjustments in their respective Percentage Shares allocable to such Letter of Credit pursuant to Section 2.18(b), with the balance of such fee, if any, payable to Issuing Lender for its own account.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(b) The Borrower shall pay directly to such Issuing Lender for its own account a fronting fee (i) with respect to each commercial Letter of Credit, at the rate of annum set forth in the Issuing Lender Fee Letter, computed on the amount of such Letter of Credit, and payable upon the issuance thereof, (ii) with respect to any amendment of a commercial Letter of Credit increasing the amount of such Letter of Credit, at a rate separately agreed between the Borrower and such Issuing Lender, computed on the amount of such increase, and payable upon the effectiveness of such amendment, and (iii) with respect to each standby Letter of Credit, at the rate per annum set forth in the Issuing Lender Fee Letter, computed on the daily amount available to be drawn under such Letter of Credit on a quarterly basis in arrears, and due and payable on the L/C Fee Payment Date, commencing with the first such date to occur after the issuance of such Letter of Credit, on the L/C Expiration Date and thereafter on demand. For purposes of computing the daily amount available to be drawn under any Letter of Credit, the amount of such Letter of Credit shall be determined in accordance with Section 1.3. In addition, the Borrower shall pay directly to such Issuing Lender for its own account the customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of such Issuing Lender relating to letters of credit as from time to time in effect. Such customary fees and standard costs and charges are due and payable on demand and are nonrefundable.

Section 2.14. Borrowing Base and Collateral Value Determination

(a) During the period from the Closing Date to the first Determination Date following the Closing Date redetermining the Borrowing Base, the Borrowing Base is $4,000,000,000. The Borrowing Base will be in effect as of the Closing Date and at any time that (i) the rating for the Index Debt by S&P is equal to or less favorable than BB or (ii) the rating for the Index Debt by ▇▇▇▇▇’▇ is equal to or less favorable than Ba2 or (iii) neither S&P nor Moody’s maintains a rating for Index Debt; provided that if a rating for the Index Debt shall be maintained by only one of S&P and Moody’s, the Borrowing Base will be in effect at any time that such rating is the applicable rating specified under clause (i) or (ii). At any time that the foregoing sentence is not applicable, the Borrowing Base will be in effect, but will cease to be in effect when the Borrower has provided the Administrative Agent and the Lenders written notice of their election to have availability under this Agreement governed without reference to the Borrowing Base no later than 30 days prior to the effective date of such election, except during any period as the Borrower has otherwise elected in accordance with Section 2.14(b) to have availability under this Agreement governed by the Borrowing Base. If the Borrowing Base shall not be in effect, availability under this Agreement shall be determined with reference to the Total Revolving Commitments. The Collateral Value determination shall cease to be made after the Collateral Release Date.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(b) If the Borrower has previously elected to have availability under this Agreement governed without reference to the Borrowing Base, the Borrower may from time to time elect to have availability under this Agreement governed by the Borrowing Base for the period between the next two successive scheduled Determination Dates (a “Borrowing Base Period”) by giving the Administrative Agent and the Lenders written notice of their election no later than 30 days prior to the delivery under Section 6.2(d) of the next scheduled semi-annual Engineering Report. Once such election is made, the Borrower may elect to opt out of such election only at the end of any Borrowing Base Period, if the Borrowing Base is not required to be in effect under Section 2.14(a), by giving the Administrative Agent and the Lenders written notice of its election to opt out of its election no later than 30 days prior to the delivery under Section 6.2(d) of the next scheduled semi-annual Engineering Report prior to the end of such Borrowing Base Period.

(c) During the period from the Closing Date to the first Determination Date redetermining the Collateral Value, the Collateral Value is $6,082,003,900.

(d) Within 45 days after receiving the relevant Engineering Reports with respect to any Evaluation Date and the respective accompanying reports and information thereto required to be furnished pursuant to Section 6.2(d), or as promptly thereafter as practicable, the Majority Lenders (or, in the case of any increase in the Borrowing Base, the Administrative Agent and the holders of more than 90% of the Total Revolving Commitments then in effect or, if the Revolving Commitments have been terminated, the Total Revolving Extensions of Credit then outstanding) shall agree upon an amount for the Collateral Value or the Borrowing Base, as the case may be, as applicable with respect to such Evaluation Date, and the Administrative Agent shall by notice to the Borrower designate such amounts as the new Collateral Value and Borrowing Base, respectively, which designation shall take effect immediately on the date of such notice (herein called a “Determination Date”) and shall remain in effect until but not including the next date as of which the Collateral Value or the Borrowing Base, as the case may be, are redetermined. If the Borrower does not furnish all such information, reports and data by the date specified in Section 6.2(d), the Administrative Agent may nonetheless designate the Collateral Value or the Borrowing Base, as the case may be, at any amount which the Majority Lenders determine and may redesignate the Collateral Value or the Borrowing Base, as the case may be, from time to time thereafter in a similar manner until each Lender receives all information, reports and data, whereupon the Majority Lenders shall designate the Collateral Value or the Borrowing Base, as the case may be, as described above. The Majority Lenders shall determine the Collateral Value based on the reports delivered pursuant to Section 6.2(d) and the applicable price assumptions used by the Reference Bank in evaluating its oil and gas loans generally as determined by the Reference Bank and such determination of the Collateral Value shall deduct the net present value of the reserves projected to be produced on or prior to the next scheduled Evaluation Date. The Majority Lenders shall determine the amount of the Borrowing Base based (i) upon the total debt of the Company and its Subsidiaries and upon the loan value which they in their discretion assign to the various oil and gas properties of the Company and its Subsidiaries at such time and (ii) upon such other credit factors (including, without limitation, (A) the assets, liabilities, cash flow, hedged and unhedged exposure to price, agreements affecting reserves, business, properties, prospects, production history of reserves, nature of the ownership of the reserves, Liens affecting properties, management and ownership of the Company and its Subsidiaries, (B) foreign exchange rate changes and interest rate changes, (C) the general policies of the Majority Lenders from time to time with respect to the prices used in evaluating their oil and gas loans generally and (D) the Collateral) as they in their discretion deem significant. It is expressly understood that the Lenders and the Administrative Agent have no obligation to agree upon or designate the Collateral Value or the Borrowing Base at any particular amount. It is further expressly understood that no determinations or designations of the Borrowing Base will be made or will be effective, and the references to the Borrowing Base in this Section 2.14(d) shall be disregarded, at any time that the Borrowing Base is not in effect as provided in Section 2.14(a).


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(e) Until the termination of the Revolving Commitment Period, the Borrower may, during the 15-day period beginning on each Determination Date, reduce the Borrowing Base, when in effect, from the amount designated by the Administrative Agent to any lesser amount by delivering a notice during such period to the Administrative Agent to that effect, with such reduction to be effective as of the date such notice is received by the Administrative Agent and shall continue in effect until such time as the Borrowing Base is redetermined in accordance with Section 2.14(d) or not in effect in accordance with Section 2.14(a).

(f) Concurrently with the delivery of the notice by the Borrower of its election to have availability under this Agreement governed without reference to the Borrowing Base and with each delivery of an Engineering Report pursuant to Section 6.2(d) when the ratio of PV to Consolidated Indebtedness contained in Section 7.1(c) is applicable, the Borrower will provide to the Administrative Agent and Lenders a certificate of a Responsible Officer of the Company and of the Borrower reflecting in reasonable detail the calculation of PV.

(g) All of the Collateral consisting of the Mortgaged Properties (but excluding Cash Collateral to the extent applicable) shall be released by the Administrative Agent promptly following the written request of the Borrower made to the Administrative Agent so long as all of the following conditions are satisfied on the date of such actual release (the date of the actual release called “Collateral Release Date”): (i) the ratings of the Index Debt shall be maintained by S&P at BBB- or better and shall be maintained by Moody’s at Baa3 or better; provided that if only one of S&P or Moody’s provides a rating for the Index Debt such rating shall be maintained at BBB- or better or Baa3 or better, as applicable; (ii) all Liens permitted under Section 7.3(j) or (m) and all covenants and agreements relating to the Indebtedness and obligations referred to in Section 7.3(j) or (m) that require or could require Liens to secure such Indebtedness and obligations have been released and discharged; and (iii) no Default or Event of Default shall have occurred and be continuing or shall result therefrom.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(h) The Borrower shall be entitled (at its own cost and expense) at any time and from time to time to mortgage and grant to the Administrative Agent for the benefit of the Lenders additional Collateral in substitution for any part of the then existing Collateral, provided that: (i) no Default exists and no Default would exist after giving effect to such release; (ii) after giving effect thereto, the Collateral Coverage Ratio is not less than the Minimum Collateral Coverage Ratio; (iii) for any new Collateral to be granted or pledged by the Borrower, the Borrower shall have taken the related actions and made the deliveries required under Section 6.10; and (iv) after giving effect to such substitution, the Collateral being substituted would not cause the value of all substituted and released Collateral substituted or released since the most recent Determination Date to be in excess of 33% of the Collateral Value (as of the most recent Determination Date), as determined, in the case of any substitution of less than or equal to 10% of the Collateral Value, by the Administrative Agent or as determined, in the case of any substitution of more than 10% but less than 33% of the Collateral Value, collectively by the Administrative Agent and at least one other Agent Bank. A substitution of Collateral with a value less than 100% of the value of the Collateral that has been released will be treated as both a release and substitution for purposes of the calculations in this Section 2.14(h) and in Section 2.14(i), as applicable, above and the conditions and requirements in each of such Sections shall be satisfied in respect of each such substitution. Upon request, Collateral may be released and/or exchanged for substitute oil and gas property interests Collateral without the need for a new Collateral Value determination, so long as (i) the Minimum Collateral Coverage Ratio and the collateral requirements are maintained, as determined as set forth above, with respect to any new oil and gas property interests Collateral given in exchange for released collateral, by the Company, the Administrative Agent and any additional Agent Bank, if applicable, and (ii) the aggregate value of all released and substituted collateral since the most recent Collateral Value determination is less than 33% of such Collateral Value.

(i) Upon written request by the Borrower to the Administrative Agent, the Administrative Agent shall execute releases in the form provided to it by the Borrower and acceptable to the Administrative Agent at the cost and expense of the Borrower thereby releasing one or more properties from the Lien of the Mortgages in accordance with the terms set forth herein and therein, provided in each case that: (i) after giving effect thereto, the Collateral Coverage Ratio is not less than the Minimum Collateral Coverage Ratio; (ii) no Default exists and no Default would exist after giving effect to such release; and (iii) if after giving effect to such release, the Collateral being released would not cause the value of all released and substituted Collateral released or substituted since the most recent Evaluation Date to be in excess of 33% of the Collateral Value (as of the most recent Determination Date), as determined, in the case of any release or substitution of less than or equal to10% of the Collateral Value, by the Administrative Agent or as determined, in the case of any release or substitution of more than 10% but less than 33% of the Collateral Value, collectively by the Administrative Agent and at least one other Agent Bank.

Section 2.15. Increase in Commitments.

(a) Request for Increase. Provided no Default has occurred and is continuing, upon notice to the Administrative Agent (which shall promptly notify the Lenders), the Borrower may from time to time request an increase in the Total Revolving Commitments; provided that (i) any such request for an increase shall be in a minimum amount of $25,000,000, (ii) the Borrower may make a maximum of five such requests during the Revolving Commitment Period, (iii) after giving effect to such increase in the Total Revolving Commitments, the Total Revolving Commitments do not exceed the lesser of (A) $5,000,000,000 or (B) the Borrowing Base then in effect, if applicable and (iv) if such request for an increase in the Total Revolving Commitments occurs prior to the Collateral Release Date, sufficient collateral is provided to maintain the Collateral Coverage Ratio required by Section 6.9; the Collateral Value of any such additional collateral to be established by Majority Lenders pursuant to the procedures set forth in Section 2.14(d). At the time of sending such notice, the Borrower may request all or part of such increase from the Lenders and, if it does so, shall specify (in consultation with the Administrative Agent) the time period within which each Lender who desires to commit to such increase is requested to respond.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(b) Lender Elections to Increase. If Borrower so requests, each Lender may notify the Administrative Agent within such time period whether or not it agrees to increase its Revolving Commitment (which agreement may be given or withheld at such Lender’s sole and absolute discretion) and, if so, whether by an amount equal to, greater than, or less than its Revolving Percentage of such requested increase. Any Lender not responding within such time period shall be deemed to have declined to increase its Revolving Commitment.

(c) Notification by Administrative Agent; Additional Lenders. The Administrative Agent shall notify the Borrower and each Lender of the Lenders’ responses to each request made hereunder. To achieve the full amount of a requested increase and subject to the approval of the Administrative Agent, the Swing Line Lender and each Issuing Lender (which approvals shall not be unreasonably withheld), the Borrower may also invite additional Persons who qualify as Eligible Assignees to become Lenders pursuant to a joinder agreement in form and substance satisfactory to the Administrative Agent and its counsel. It shall not be a condition to obtaining an increase in the Total Revolving Commitments that the full amount of such increase requested by the Borrower be approved by the Lenders or any additional Eligible Assignees. If less than the full amount of the increase requested by the Borrower is approved by the Lenders and any additional Eligible Assignee, the Borrower may, at its option, accept the amount of the increase so approved, or the Borrower may withdraw its request for such increase, in which case the Borrower shall be deemed not to have made a request for such increase.

(d) Effective Date and Allocations. If the Total Revolving Commitments are increased in accordance with this Section 2.15, the Administrative Agent and the Borrower shall determine the effective date (the “Increase Effective Date”) and the final allocation of such increase. The Administrative Agent shall promptly notify the Borrower and the Lenders of the final amount and allocation of such increase and the Increase Effective Date.

(e) Conditions to Effectiveness of Increase. As a condition precedent to such increase, the Borrower shall deliver to the Administrative Agent a certificate of each Loan Party dated as of the Increase Effective Date (in sufficient copies for each Lender) signed by a Responsible Officer of such Loan Party (i) certifying and attaching the resolutions adopted by such Loan Party approving or consenting to such increase, and (ii) in the case of the Borrower, certifying that, before and after giving effect to such increase, (A) the representations and warranties contained in Article 4 and the other Loan Documents are true and correct on and as of the Increase Effective Date, (B) no Default exists and (C) after giving effect to such increase, (1) no Borrowing Base Deficiency exists and (2) if such Increase Effective Date is prior to the Collateral Release Date, the Collateral Coverage Ratio is not less than the Minimum Collateral Coverage Ratio. Administrative Agent shall notify the new or increasing Lenders of the amount of Loans of each Type and the applicable Interest Period thereof, and each such new or increasing Lender shall make Revolving Loans which are sufficient to make its outstanding Revolving Loans of each Type and of each Interest Period equal to such Lender’s Revolving Percentage of the Revolving Loans of such Type and such Interest Period. The Borrower shall pay to such new or increasing Lenders on the Increase Effective Date any costs reasonably determined by such Lender to have been incurred in respect of Eurodollar Loans related to such increase which are funded other than on the first day of the Interest Period relating thereto.

(f) Conflicting Provisions. This Section shall supersede any provisions in Section 3.8 or Section 10.1 to the contrary.

Section 2.16. Extension of Revolving Termination Date.

(a) Not earlier than 60 days prior to, nor later than 30 days prior to, any anniversary date of the Closing Date, the Borrower may, upon notice to the Administrative Agent (who shall promptly notify the Lenders), request a one year extension of the then current Revolving Termination Date, provided, however, that the Borrower may request only two such extensions under this Agreement. Within 15 days of delivery of such notice, each Lender shall notify the Administrative Agent whether or not it consents to such extension (which consent may be given or withheld in such Lender’s sole and absolute discretion). Any Lender not responding within the above time period shall be deemed not to have consented to such extension. The Administrative Agent shall promptly notify the Borrower and the Lenders of the Lenders’ responses. If any Lender declines, or is deemed to have declined, to consent to such extension (a “Declining Lender”), the Borrower may cause any such Declining Lender to be removed or replaced as a Lender pursuant to Section 3.13.

(b) Only if Majority Lenders (calculated prior to giving effect to any removals and/or replacements of Lenders permitted herein) (the “Consenting Lenders”) have consented to an extension requested pursuant to this Section, the Revolving Termination Date shall be extended, with respect only to the Consenting Lenders and any Lender replacing a Declining Lender pursuant to Section 3.13. If so extended, the Revolving Termination Date, as to the Consenting Lenders and each Lender replacing a Declining Lender pursuant to Section 3.13, shall be extended to the date falling one year after the existing Revolving Termination Date (except that if such date is not a Business Day, such Revolving Termination Date, as so extended, shall be the next preceding Business Day); provided, however, that the pre-existing Revolving Termination Date shall remain in effect with respect to any Declining Lender that is not replaced (such Declining Lender’s “Existing Maturity Date”). The Administrative Agent and the Borrower shall promptly confirm to the Lenders such extension, and the Administrative Agent shall distribute an amended Schedule 2.01 (which shall be deemed incorporated into this Agreement), to reflect any changes in Lenders and their respective Revolving Commitments. If the Revolving Termination Date is extended pursuant this Section 2.16 with respect to some but not all of the Lenders, then no Letter of Credit may expire after the date that is five Business Days prior to an Existing Maturity Date in respect of any Declining Lender if, after giving effect to such Letter of Credit, the aggregate Revolving Commitments of the Consenting Lenders (including any replacement Lenders) for the period following such Existing Maturity Date would be less than the L/C Obligations following such Existing Maturity Date.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(c) As a condition precedent to such extension, the Borrower shall have provided to the Administrative Agent the following, in form and substance satisfactory to the Administrative Agent (i) copies of corporate resolutions certified by the Secretary or Assistant Secretary of the Borrower, or such other evidence as may be satisfactory to the Administrative Agent, demonstrating that the Borrower’s incurrence of indebtedness hereunder with a maturity date of the Revolving Termination Date, as extended pursuant to this Section, has been duly authorized by all necessary corporate action, together with an opinion of counsel to the Borrower to such effect, (ii) a certificate (in sufficient copies for each Lender), signed by a Responsible Officer of the Borrower certifying that, (A) before and after giving effect to such extension, the representations and warranties contained in Article 4 and the other Loan Documents are true and correct on and as of the date thereof, and (B) no Default or Event of Default exists.

(d) The Borrower shall, on the Existing Maturity Date with respect to any Declining Lender that has not been replaced as a Lender pursuant to Section 3.13 pay in full all Obligations owing to such Declining Lender, and such Declining Lender’s Revolving Commitment and participation in any Letter of Credit outstanding hereunder shall terminate on such Existing Maturity Date.

Section 2.17. Swing Line Loans.

(a) The Swing Line. Subject to the terms and conditions set forth herein, the Swing Line Lender agrees, in reliance upon the agreements of the other Lenders set forth in this Section 2.17, to make loans (each such loan, a “Swing Line Loan”) to the Borrower from time to time on any Business Day during the Revolving Commitment Period in an aggregate amount that will not cause, after giving effect to such Swing Line Loan, the outstanding amount of the Swing Line Loans to exceed the Swing Line Sublimit, notwithstanding the fact that such Swing Line Loans, when aggregated with the Total Revolving Extensions of Credit of the Lender acting as Swing Line Lender, may exceed the amount of such Lender’s Revolving Commitment; provided, however, that after giving effect to any Swing Line Loan, (A) the Total Revolving Extensions of Credit shall not exceed the Total Revolving Commitments, and (B) the Revolving Extensions of Credit of any Lender shall not exceed such Lender’s Revolving Commitment, and provided, further, that the Borrower shall not use the proceeds of any Swing Line Loan to refinance any outstanding Swing Line Loan. Within the foregoing limits, and subject to the other terms and conditions hereof, the Borrower may borrow under this Section 2.17, prepay under Section 2.17(h), and reborrow under this Section 2.17. Immediately upon the making of a Swing Line Loan, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swing Line Lender a risk participation in such Swing Line Loan in an amount equal to the product of such Lender’s Revolving Percentage of the Total Revolving Commitments times the amount of such Swing Line Loan.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(b) Borrowing Procedures. The provisions of Section 2.2 shall not apply to Borrowings of Swing Line Loans. Each Swing Line Borrowing shall be made upon the Borrower’s irrevocable notice to the Swing Line Lender and Administrative Agent, which may be given by telephone. Each such notice must be received by the Swing Line Lender and Administrative Agent not later than 1:30 P.M., Los Angeles, California time, on the requested borrowing date if the requested amount is less than $50,000,000, and otherwise not later than 9:00 A.M., Los Angeles, California time, on the requested borrowing date, and shall specify (i) the amount to be borrowed, which shall be a minimum of $2,500,000 or whole multiples of $1,000,000 in excess thereof, and (ii) the requested borrowing date, which shall be a Business Day. Each such telephonic notice must be confirmed promptly by delivery to the Swing Line Lender and Administrative Agent of a written Swing Line loan notice, appropriately completed and signed by a Responsible Officer of the Borrower. Promptly after receipt by the Swing Line Lender of any telephonic Swing Line loan notice, the Swing Line Lender will confirm with Administrative Agent (by telephone or in writing) that Administrative Agent has also received such Swing Line loan notice and, if not, the Swing Line Lender will notify Administrative Agent (by telephone or in writing) of the contents thereof. Unless the Swing Line Lender has received notice (by telephone or in writing) from Administrative Agent (including at the request of any Lender) prior to 11:00 A.M., Los Angeles, California time, on the date of the proposed Swing Line Borrowing (A) directing the Swing Line Lender not to make such Swing Line Loan as a result of the limitations set forth in the first proviso to the first sentence of Section 2.17(a), or (B) that one or more of the applicable conditions specified in Article 5 is not then satisfied, then, subject to the terms and conditions hereof, the Swing Line Lender will, not later than 11:00 A.M., Los Angeles, California time, on the borrowing date specified in such Swing Line loan notice, make the amount of its Swing Line Loan available to the Borrower. Without limiting a form of notice permitted under this Agreement, it is understood that a written notice of a borrowing request or a written confirmation of an oral notice of a borrowing request may be signed by: (i) means of a facsimile or stamp signature of a Responsible Officer of the Borrower or (ii) by another officer of the Borrower who has been authorized to make such requests, if the funds are made available to the Borrower pursuant to the terms of a repetitive wire transfer instruction or authorization acceptable to the Administrative Agent.

(i) The Swing Line Lender at any time in its sole and absolute discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes the Swing Line Lender to so request on its behalf), that each Lender make a Revolving Loan at the Base Rate in an amount equal to such Lender’s Revolving Percentage of the amount of Swing Line Loans then outstanding. Such request shall be made in writing (which written request shall be deemed to be a loan notice for purposes hereof) and in accordance with the requirements of Section 2.2, without regard to the minimum and multiples specified therein for the principal amount of Base Rate Loans, but subject to the unutilized portion of the Total Revolving Commitments and the conditions set forth in Section 5.2. The Swing Line Lender shall furnish the Borrower with a copy of the applicable loan notice promptly after delivering such notice to Administrative Agent. Each Lender shall make an amount equal to its Revolving Percentage of the amount specified in such loan notice available to Administrative Agent in immediately available funds for the account of the Swing Line Lender at Administrative Agent’s Office not later than 11:00 A.M., Los Angeles, California time, on the day specified in such loan notice, whereupon, subject to Section 2.17(c)(ii), each Lender that so makes funds available shall be deemed to have made a Revolving Loan at the Base Rate to the Borrower in such amount. Administrative Agent shall remit the funds so received to the Swing Line Lender.

(ii) If for any reason any Swing Line Loan cannot be refinanced by such a Revolving Loan in accordance with Section 2.17(c)(i), the request for Revolving Loans at the Base Rate submitted by the Swing Line Lender as set forth herein shall be deemed to be a request by the Swing Line Lender that each of the Lenders fund its risk participation in the relevant Swing Line Loan and each Lender’s payment to Administrative Agent for the account of the Swing Line Lender pursuant to Section 2.17(c)(i) shall be deemed payment in respect of such participation.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(iii) If any Lender fails to make available to Administrative Agent for the account of the Swing Line Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.17(c) by the time specified in Section 2.17(c)(i), the Swing Line Lender shall be entitled to recover from such Lender (acting through Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Swing Line Lender at a rate per annum equal to the greater of the Federal Funds Effective Rate and a rate determined by the Swing Line Lender in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the Swing Line Lender in connection with the foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute such Lender’s Revolving Loan included in the relevant Swing Line Loan or funded participation in the relevant Swing Line Loan, as the case may be. A certificate of the Swing Line Lender submitted to any Lender (through Administrative Agent) with respect to any amounts owing under this clause (iii) shall be conclusive absent manifest error.

(iv) Each Lender’s obligation to make Revolving Loans or to purchase and fund risk participations in Swing Line Loans pursuant to this Section 2.17(c) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Swing Line Lender, the Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Lender’s obligation to make Revolving Loans pursuant to this Section 2.17(c) is subject to the conditions set forth in Section 5.2. No such funding of risk participations shall relieve or otherwise impair the obligation of the Borrower to repay Swing Line Loans, together with interest as provided herein.

(d) Repayment of Participations. At any time after any Lender has purchased and funded a risk participation in a Swing Line Loan, if the Swing Line Lender receives any payment on account of such Swing Line Loan, the Swing Line Lender will distribute to such Lender its Revolving Percentage thereof in the same funds as those received by the Swing Line Lender.

(e) Interest for Account of Swing Line Lender. The Swing Line Lender shall be responsible for invoicing the Borrower for interest on the Swing Line Loans. Until each Lender funds its Revolving Loan or risk participation pursuant to this Section 2.17 to refinance such Lender’s Revolving Percentage of any Swing Line Loan, interest in respect of such Lender’s Revolving Percentage share shall be solely for the account of the Swing Line Lender.

(f) Payments Directly to Swing Line Lender. The Borrower shall make all payments of principal and interest in respect of the Swing Line Loans directly to the Swing Line Lender


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(g) Swing Line Loan Interest. Each Swing Line Loan shall bear interest on the outstanding principal amount thereof on each day at a per annum rate equal to the rate for overnight (next business day) Dollar deposits in the interbank eurodollar market as determined by Swing Line Lender plus the Applicable Margin with respect to Eurodollar Loans; provided, however, that if the Swing Line Lender determines that it is not able to determine such rate for any day or to maintain Swing Line Loans at such rate for any day, each Swing Line Loan shall bear interest on the outstanding principal amount thereof on such day at a per annum rate equal to the Base Rate plus the Applicable Margin with respect to Base Rate Loans.

(h) Voluntary Pre-Payments. The Borrower may, upon notice to the Swing Line Lender (with a copy to Administrative Agent), at any time or from time to time, voluntarily prepay Swing Line Loans in whole or in part without premium or penalty; provided that (i) such notice must be received by the Swing Line Lender and Administrative Agent not later than 1:30 P.M., Los Angeles, California time, on the requested borrowing date if the requested amount is less than $50,000,000, and otherwise not later than 11:00 A.M., Los Angeles, California time, on the date of the prepayment, and (ii) any such prepayment shall be in a minimum principal amount of $100,000. Each such notice shall specify the date and amount of such prepayment. If such notice is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein.

(i) Repayment of Swing Line Loans. The Borrower shall repay each Swing Line Loan on the earlier to occur of (i) the date fifteen Business Days after such Loan is made and (ii) the Revolving Termination Date.

(j) Evidence of Swing Line Loan Debt. In addition to the accounts and records referred to in Section 3.14, each Lender and Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of Swing Line Loans. In the event of any conflict between the accounts and records maintained by Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of Administrative Agent shall control in the absence of manifest error.

Section 2.18. Defaulting Lenders.

(a) Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as that Lender is no longer a Defaulting Lender, to the extent permitted by applicable Law:

(i) Waivers and Amendments. That Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in Section 10.1.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(ii) Reallocation of Payments. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of that Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article 3 or 8 or otherwise, and including any amounts made available to the Administrative Agent by that Defaulting Lender pursuant to Section 10.07), shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by that Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by that Defaulting Lender to Issuing Lender or Swing Line Lender hereunder; third, if so determined by the Administrative Agent or requested by Issuing Lender or Swing Line Lender, to be held as Cash Collateral for future funding obligations of that Defaulting Lender of any participation in any Swing Line Loan or Letter of Credit; fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which that Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrower, to be held in a non-interest bearing deposit account and released in order to satisfy obligations of that Defaulting Lender to fund Loans under this Agreement; sixth, to the payment of any amounts then owing to Lenders, Issuing Lender or Swing Line Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, Issuing Lender or Swing Line Lender against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts then owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to that Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or Matured LC Obligations in respect of which that Defaulting Lender has not fully funded its appropriate share and (y) such Loans or Matured LC Obligations were made at a time when the conditions set forth in Section 5.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and Matured LC Obligations owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or Matured LC Obligations owed to, that Defaulting Lender. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.18(a)(ii) shall be deemed paid to and redirected by that Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees. That Defaulting Lender (x) shall not be entitled to receive any Commitment Fee pursuant to Section 2.3 for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender) (y) shall be limited in its right to receive Letter of Credit Fees as provided in Section 2.13.

(b) Reallocation of Percentage Shares to Reduce Fronting Exposure. During any period in which there is a Defaulting Lender, for purposes of computing the amount of the obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit pursuant to Section 2.11, the “Aggregate Exposure Percentage” of each non-Defaulting Lender shall be computed without giving effect to the Commitment of that Defaulting Lender; provided, that, (i) each such reallocation shall be given effect only if, at the date the applicable Lender becomes a Defaulting Lender, no Default or Event of Default exists; and (ii) the aggregate obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit shall not exceed the positive difference, if any, of (1) the Commitment of that non-Defaulting Lender minus (2) the aggregate outstanding amount of the Loans of that Lender.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(c) Defaulting Lender Cure. If the Borrower, the Administrative Agent and Issuing Lender agree in writing in their discretion that a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which conditions may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit to be held on a pro rata basis by the Lenders in accordance with their Percentage Shares (without giving effect to Section 2.18(b), whereupon that Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

ARTICLE 3.

GENERAL PROVISIONS APPLICABLE TO REVOLVING LOANS

AND LETTERS OF CREDIT

Section 3.1. Optional Prepayments. The Borrower may at any time and from time to time prepay the Revolving Loans, in whole or in part, without premium or penalty, upon irrevocable notice delivered to the Administrative Agent at least three Business Days prior thereto in the case of Eurodollar Loans and prior to 9:00 am Los Angeles, CA time on the day of the requested repayment, in the case of Base Rate Loans, which notice shall specify the date and amount of prepayment and whether the prepayment is of Eurodollar Loans or Base Rate Loans; provided, that if a Eurodollar Loan is prepaid on any day other than the last day of the Interest Period applicable thereto, the Borrower shall also pay any amounts owing pursuant to Section 3.11. Upon receipt of any such notice the Administrative Agent shall promptly notify each Lender thereof. If any such notice is given, the amount specified in such notice shall be due and payable on the date specified therein, together with (except in the case of Revolving Loans that are Base Rate Loans) accrued interest to such date on the amount prepaid. Partial prepayments of Revolving Loans shall be in an aggregate principal amount of $2,500,000 or whole multiples of $500,000 in excess thereof.

Section 3.2. Mandatory Prepayments

(a) If at any time prior to the Collateral Release Date the Collateral Coverage Ratio is less than 1.4 to 1.0 (the “Collateral Deficiency Date”), the Borrower shall either:

(i) Give notice to the Administrative Agent that they elect to reduce the Borrowing Base, if applicable, or the Total Revolving Commitments and prepay the Revolving Loans to the extent necessary to comply with the Collateral Coverage at such time whereupon the Borrowing Base, if applicable, or the Total Revolving Commitments shall be so reduced with immediate effect and the Borrower shall make such prepayment on or before the date that is 30 days after the related Collateral Deficiency Date and to the extent such prepayment of the aggregate principal amount of Revolving Loans then outstanding is insufficient to result in compliance with the Collateral Coverage Ratio, the Borrower shall, to the extent of such deficiency, replace outstanding Letters of Credit and/or Cash Collateralize L/C Obligations; or


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(ii) Certify to the Administrative Agent that the Borrower has good and defensible title, free of any Liens, to Proved Developed Properties in an amount which, if subject to one or more Mortgages, would result in the Borrower being in compliance with such Collateral Coverage Ratio (including the value of the related Other Proved Reserves to the extent provided in the definition of Collateral Value), and provide to each Lender the same information regarding such Proved Developed Properties as would be required for an evaluation of the Collateral Value attributable thereto by the Majority Lenders under Section 2.14. Within 10 days after such certification, the Majority Lenders shall either (x) determine that such properties, if subject to a Mortgage, would result in the Borrower being in compliance with such Collateral Coverage Ratio in which case, the Borrower shall within 20 days of such certification, and in any event, no later than within 30 days of the Collateral Deficiency Date, deliver a Mortgage (or a satisfactory amendment to an Existing Mortgage) to the Administrative Agent with respect to each of such Proved Developed Properties, executed and delivered by a duly authorized officer of each party thereto and accompanied by such other documentation as the Administrative Agent shall reasonably request (including, without limitation, legal opinions in form and substance satisfactory to the Administrative Agent relating thereto) or (y) determine that such properties, if subject to a Mortgage, would not result in the Borrower being in compliance with such Collateral Coverage Ratio in which case, the Borrower shall make the prepayments specified in subsection (i) of this Section 3.2(a) within 30 days of the Collateral Deficiency Date.

(b) If at any time the Borrowing Base is in effect (A) the Total Revolving Extensions of Credit exceed (B) the Borrowing Base at such time (such excess, the “Borrowing Base Deficiency”) the Administrative Agent shall give notice thereof to the Borrower (a “Borrowing Base Deficiency Notice”) and within 30 days after the date of such Borrowing Base Deficiency Notice, the Borrower shall either:

(i) Give notice to the Administrative Agent that they elect to prepay the Revolving Loans in an amount at least equal to the Borrowing Base Deficiency whereupon the Borrower shall make such prepayment on or before the date that is 60 days after the date of the Borrowing Base Deficiency Notice and, to the extent such prepayment of the aggregate principal amount of Revolving Loans then outstanding is less than such Borrowing Base Deficiency, the Borrower shall, to the extent of such shortfall, replace outstanding Letters of Credit and/or Cash Collateralize L/C Obligations; or

(ii) Give notice to the Administrative Agent that they elect to prepay the Revolving Loans in an aggregate amount equal to the Borrowing Base Deficiency (or, to the extent such prepayments of the aggregate principal amount of Revolving Loans then outstanding are less than the Borrowing Base Deficiency, replace outstanding Letters of Credit and/or Cash Collateralize L/C Obligations) in six consecutive equal monthly installments, whereupon the Borrower shall pay the first such installment 30 days after the date of the Borrowing Base Deficiency and the next five such installments on the same day of each consecutive month thereafter; or

(iii) (A) Certify to the Administrative Agent that the Borrower has good and defensible title, free of any Liens, to oil and gas properties not included in the determination of the Borrowing Base then in effect in an amount which, if taken into account in such determination, would eliminate the Borrowing Base Deficiency, and (B) provide to each Lender the same information regarding such properties as would be required for an evaluation of the value attributable thereto by the Majority Lenders under Section 2.14 in calculating the Borrowing Base. Within 30 days after such certification, if the Majority Lenders shall determine that taking into account such properties in the determination of the Borrowing Base would not be sufficient to result in the elimination of the Borrowing Base Deficiency, the Borrower shall either (x) make the prepayments specified in subsection (i) of this Section 3.2(b) immediately or (y) make the installment prepayments specified in subsection (ii) of this Section 3.2(b) with the first such installment due immediately.

Section 3.3. Conversion and Continuation Options

(a) The Borrower may elect from time to time to convert Eurodollar Loans to Base Rate Loans by giving the Administrative Agent prior irrevocable notice of such election by 9:00 A.M., Los Angeles, California time, three Business Days preceding the day on which such conversion is to occur, provided that any such conversion of Eurodollar Loans may only be made on the last day of an Interest Period with respect thereto. The Borrower may elect from time to time to convert Base Rate Loans to Eurodollar Loans by giving prior irrevocable notice to the Administrative Agent by 9:00 A.M., Los Angeles, California time, three Business Days prior to such conversion (which notice shall specify the length of the initial Interest Period therefor), provided that no Base Rate Loan may be converted into a Eurodollar Loan when any Event of Default has occurred and is continuing and the Administrative Agent or the Majority Lenders have determined in its or their sole discretion not to permit such conversions. Upon receipt of any such notice the Administrative Agent shall promptly notify each Lender thereof.

(b) Any Eurodollar Loan may be continued as such upon the expiration of the then current Interest Period with respect thereto by the Borrower giving irrevocable notice to the Administrative Agent, in accordance with the applicable provisions of the term “Interest Period” set forth in Section 1.1, of the length of the next Interest Period to be applicable to such Eurodollar Loans, provided that no Eurodollar Loan may be continued as such when any Event of Default has occurred and is continuing and the Administrative Agent has or the Majority Lenders have determined in its or their sole discretion not to permit such continuations, and provided, further, that if the Borrower shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso such Eurodollar Loans shall be automatically converted to Base Rate Loans on the last day of such then expiring Interest Period. Upon receipt of any such notice the Administrative Agent shall promptly notify each Lender thereof.

Section 3.4. Limitations on Eurodollar Tranches. Notwithstanding anything to the contrary in this Agreement, all borrowings, conversions and continuations of Eurodollar Loans hereunder and all selections of Interest Periods hereunder shall be in such amounts and be made pursuant to such elections so that, (a) after giving effect thereto, the aggregate principal amount of the Eurodollar Loans comprising each Eurodollar Tranche shall be equal to $2,500,000 or whole multiples of $500,000 in excess thereof and (b) no more than twelve Eurodollar Tranches shall be outstanding at any one time.

Section 3.5. Interest Rates and Payment Dates

(a) Each Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to the Eurodollar Rate determined for such day plus the Applicable Margin.

(b) Each Base Rate Loan shall bear interest at a rate per annum equal to the Base Rate plus the Applicable Margin.

(c) (i) If all or a portion of the principal amount of any Revolving Loan or L/C Obligation shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum equal to (x) in the case of the Revolving Loans, the rate that would otherwise be applicable thereto pursuant to the foregoing provisions of this Section plus 2% or (y) in the case of L/C Obligations, the rate applicable to Base Rate Loans plus 2%, and (ii) if all or a portion of any interest payable on any Revolving Loan or L/C Obligation or any commitment fee or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum equal to the rate then applicable to Base Rate Loans plus 2%, in each case, with respect to clauses (i) and (ii) above, from the date of such non-payment until such amount is paid in full (as well after as before judgment).

(d) Interest shall be payable in arrears on each Interest Payment Date, provided that interest accruing pursuant to paragraph (c) of this Section shall be payable from time to time on demand.

Section 3.6. Computation of Interest and Fees

(a) Interest and fees payable pursuant hereto shall be calculated on the basis of a 360-day year for the actual days elapsed, except that, with respect to Base Rate Loans the rate of interest on which is calculated on the basis of the Reference Rate, the interest thereon shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed. The Administrative Agent shall as soon as practicable notify the Borrower and the Lenders of each determination of a Eurodollar Rate. Any change in the interest rate on a Revolving Loan resulting from a change in the Base Rate or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Borrower and the Lenders of the effective date and the amount of each such change in interest rate.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrower, deliver to the Borrower a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to Section 3.6(a).

Section 3.7. Inability to Determine Interest Rate. If prior to the first day of any Interest Period:

(a) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period; or

(b) the Administrative Agent shall have received notice from the Majority Lenders that the Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Revolving Loans during such Interest Period, the Administrative Agent shall give telefacsimile, email or telephonic notice thereof to the Borrower and the Lenders as soon as practicable thereafter. If such notice is given (x) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as Base Rate Loans, (y) any Revolving Loans that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as Base Rate Loans and (z) any outstanding Eurodollar Loans shall be converted, on the last day of the then-current Interest Period, to Base Rate Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans shall be made or continued as such, nor shall the Borrower has the right to convert Revolving Loans to Eurodollar Loans.

Section 3.8. Pro Rata Treatment and Payments.

(a) Each borrowing by the Borrower from the Lenders hereunder, each payment by the Borrower on account of any commitment fee and any reduction of the Revolving Commitments of the Lenders shall be made pro rata according to the Revolving Percentages of the Lenders.

(b) Each payment (including each prepayment) by the Borrower on account of principal of and interest on the Revolving Loans shall be made pro rata according to the respective outstanding principal amounts of the Revolving Loans then held by the Lenders.

(c) All payments (including prepayments) to be made by the Borrower hereunder, whether on account of principal, interest, fees or otherwise, shall be made without setoff or counterclaim and shall be made prior to 11:00 A.M., Los Angeles, California time, on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Funding Office, in Dollars and in immediately available funds. The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal pursuant to the preceding two sentences, interest thereon shall be payable at the then applicable rate during such extension.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(d) Unless the Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon at a rate equal to the daily average Federal Funds Effective Rate for the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this paragraph shall be conclusive in the absence of manifest error. If such Lender’s share of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days of such Borrowing Date, the Administrative Agent shall also be entitled to recover such amount with interest thereon at the rate per annum applicable to Base Rate Loans, on demand, from the Borrower.

(e) Unless the Administrative Agent shall have been notified in writing by the Borrower prior to the date of any payment due to be made by the Borrower hereunder that the Borrower will not make such payment to the Administrative Agent, the Administrative Agent may assume that the Borrower is making such payment, and the Administrative Agent may, but shall not be required to, in reliance upon such assumption, make available to the Lenders their respective pro rata shares of a corresponding amount. If such payment is not made to the Administrative Agent by the Borrower within three Business Days after such due date, the Administrative Agent shall be entitled to recover, on demand, from each Lender to which any amount which was made available pursuant to the preceding sentence, such amount with interest thereon at the rate per annum equal to the daily average Federal Funds Effective Rate. Nothing herein shall be deemed to limit the rights of the Administrative Agent or any Lender against the Borrower.

(f) The Borrower and any Lender shall have the option, from time to time, to execute and deliver to the Administrative Agent a Pari Passu Hedging Obligation Notice designating a fixed dollar amount as the allocation of the maximum amount of Pari Passu Hedging Obligations for a stated Lender and its Affiliates (a “Pari Passu Hedging Obligation Allocation”), and the Pari Passu Hedging Obligation Allocation of any Lender and its Affiliates may be terminated, increased or decreased from time to time by a subsequent Pari Passu Hedging Obligation Notice executed by the Borrower and such Lender; provided that (i) the maximum aggregate amount of all Pari Passu Hedging Obligation Allocations at any one time shall not exceed the Pari Passu Hedging Obligation Limit and (ii) no such Pari Passu Hedging Obligation Notice shall be effective until the Administrative Agent shall have executed and delivered to the Borrower and such Lender such notice confirming such Pari Passu Hedging Obligation Allocation. The Administrative Agent shall maintain a register to record all Pari Passu Hedging Obligation Allocations. The obligations under the Lender Hedge Agreements with such Lender and its Affiliates that exceed such Lender’s Pari Passu Hedging Obligation Allocation shall not be Pari Passu Hedging Obligations. The aggregate amount of Pari Passu Hedging Obligations outstanding from time to time shall be considered Obligations for purposes of each of the Security Documents and shall be secured by all the Collateral granted thereunder in accordance with the following Section 3.8(g).


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(g) Notwithstanding anything in this Section 3.8 or in any of the Loan Documents to the contrary, in the event that the Revolving Loans shall have become due and payable, and the Revolving Commitments shall have been terminated, pursuant to Article 8, any amounts received by the Administrative Agent from the Loan Parties or their Subsidiaries or from the Collateral in respect of the Borrower’s Obligations shall be applied in the following order of priority:

(i) First, to reimburse the Administrative Agent for its fees, costs and expenses pursuant to the Loan Documents;

(ii) Second, to pay unpaid interest accrued on the Revolving Loans;

(iii) Third, (A) to pay all other outstanding Obligations (whether or not contingent) under, out of, or in connection with any of the Loan Documents or Letters of Credit, including the outstanding principal of the Revolving Loans and, after the payment of the outstanding principal of the Revolving Loans, to Cash Collateralize outstanding L/C Obligations and (B) to pay Pari Passu Hedging Obligations of any Lender and its Affiliates (applied ratably to each Lender based upon (x) such Lender’s total outstanding Obligations under (A), and (y) such Lender’s or such Lender’s Affiliate’s Pari Passu Hedging Obligations under (B));

(iv) Fourth, once all of the Obligations (whether or not contingent) and Pari Passu Hedging Obligations have been indefeasibly paid in full and all Letters of Credit have been terminated or Cash Collateralized, to the Borrower.

Administrative Agent shall have no responsibility to determine the existence or amount of Pari Passu Hedging Obligations and may reserve from the application of amounts under this Section 3.8(g) amounts distributable in respect of Pari Passu Hedging Obligations until it has received evidence satisfactory to it of the existence and amount of such Pari Passu Hedging Obligations.

Section 3.9. Requirements of Law

(a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof:

(i) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any Application or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by Section 3.10 and changes in the rate of tax on the overall net income of such Lender);


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in the determination of the Eurodollar Rate hereunder; or

(iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender, by an amount that such Lender deems to be material, of making, converting into, continuing or maintaining Eurodollar Loans or issuing or participating in Letters of Credit, or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Borrower shall promptly pay such Lender, upon its demand, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this paragraph, it shall promptly notify the Borrower (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled.

(b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof shall have the effect of reducing the rate of return on such Lender’s or such corporation’s capital as a consequence of its obligations hereunder or under or in respect of any Letter of Credit to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or such corporation’s policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrower (with a copy to the Administrative Agent) of a written request therefor, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender or such corporation for such reduction.

(c) A certificate as to any additional amounts payable pursuant to this Section submitted by any Lender to the Borrower (with a copy to the Administrative Agent) shall be conclusive in the absence of manifest error. The obligations of the Borrower pursuant to this Section shall survive the termination of this Agreement and the payment of the Revolving Loans and all other amounts payable hereunder.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

Section 3.10. Taxes

(a) All payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding net income taxes and franchise taxes (imposed in lieu of net income taxes) imposed on the Administrative Agent or any Lender as a result of a present or former connection between the Administrative Agent or such Lender and the jurisdiction of the Governmental Authority imposing such tax or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from the Administrative Agent or such Lender having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any other Loan Document). If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) or Other Taxes are required to be withheld from any amounts payable to the Administrative Agent or any Lender hereunder, the amounts so payable to the Administrative Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent or such Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement, provided, however, that the Borrower shall not be required to increase any such amounts payable to any Lender with respect to any Non-Excluded Taxes (i) that are attributable to such Lender’s failure to comply with the requirements of paragraph (d) or (e) of this Section or (ii) that are United States withholding taxes imposed on amounts payable to such Lender at the time such Lender becomes a party to this Agreement, except to the extent that such Lender’s assignor (if any) was entitled, at the time of assignment, to receive additional amounts from the Borrower with respect to such Non-Excluded Taxes pursuant to this paragraph.

(b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Whenever any Non-Excluded Taxes or Other Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the Administrative Agent for their own account or for the account of the Administrative Agent or Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Administrative Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the Administrative Agent or any Lender as a result of any such failure.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(d) Each Lender (or Transferee) that is not a “U.S. Person” as defined in Section 7701(a)(30) of the Code (a “Non-U.S. Lender”) shall deliver to the Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased) two copies of either U.S. Internal Revenue Service Form W-8BEN or Form W-89ECI, or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest”, a statement substantially in the form of Exhibit G and a Form W-8BEN, or any subsequent versions thereof or successors thereto, properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by the Borrower under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to this Agreement (or, in the case of any Participant, on or before the date such Participant purchases the related participation). In addition, each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Non-U.S. Lender. Each Non-U.S. Lender shall promptly notify the Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of certification adopted by the U.S. taxing authorities for such purpose). Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall not be required to deliver any form pursuant to this paragraph that such Non-U.S. Lender is not legally able to deliver.

(e) A Lender that is entitled to an exemption from or reduction of non-U.S. 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 shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate, provided that such Lender is legally entitled to complete, execute and deliver such documentation and in such Lender’s judgment such completion, execution or submission would not materially prejudice the legal position of such Lender.

(f) The agreements in this Section shall survive the termination of this Agreement and the payment of the Revolving Loans and all other amounts payable hereunder.

Section 3.11. Indemnity. The Borrower agrees to indemnify each Lender and the Administrative Agent and to hold each Lender and the Administrative Agent harmless from any loss or expense that such Lender may sustain or incur as a consequence of (a) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (b) default by the Borrower in making any prepayment of or conversion from Eurodollar Loans after the Borrower has given a notice thereof in accordance with the provisions of this Agreement or (c) the making of a prepayment of Eurodollar Loans on a day that is not the last day of an Interest Period with respect thereto. Such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest that would have accrued on the amount so prepaid, or not so borrowed, converted or continued, for the period from the date of such prepayment or of such failure to borrow, convert or continue to the last day of such Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Eurodollar Loans provided for herein (excluding, however, the Applicable Margin included therein, if any) over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurodollar market. A certificate as to any amounts payable pursuant to this Section submitted to the Borrower by any Lender shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment of the Revolving Loans and all other amounts payable hereunder.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

Section 3.12. Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 3.9 or 3.10(a) with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Revolving Loans affected by such event with the object of avoiding the consequences of such event; provided, that such designation is made on terms that, in the sole judgment of such Lender, cause such Lender and its lending office(s) to suffer no economic, legal or regulatory disadvantage, and provided, further, that nothing in this Section shall affect or postpone any of the obligations of the Borrower or the rights of any Lender pursuant to Section 3.9 or 3.10(a).

Section 3.13. Replacement of Lenders. The Borrower shall be permitted to replace any Lender that (a) is a Defaulting Lender, (b) is a Declining Lender or (c) requests reimbursement for amounts owing pursuant to Section 3.9 or 3.10(a); provided that (i) such replacement does not conflict with any Requirement of Law, (ii) no Event of Default shall have occurred and be continuing at the time of such replacement, (iii) prior to any such replacement, such Lender shall have taken no action under Section 3.12 so as to eliminate the continued need for payment of amounts owing pursuant to Section 3.9 or 3.10(a), (iv) the replacement financial institution shall purchase, at par, all Revolving Loans and other amounts owing to such replaced Lender on or prior to the date of replacement, (v) the Borrower shall be liable to such replaced Lender under Section 3.11 if any Eurodollar Loan owing to such replaced Lender shall be purchased other than on the last day of the Interest Period relating thereto, (vi) the replacement financial institution, if not already a Lender, shall be reasonably satisfactory to the Administrative Agent, (vii) the replaced Lender shall be obligated to make such replacement in accordance with the provisions of Section 10.6 (provided that the Borrower shall be obligated to pay the registration and processing fee referred to therein), (viii) until such time as such replacement shall be consummated, the Borrower shall pay all additional amounts (if any) required pursuant to Section 3.9 or 3.10(a), as the case may be, and (ix) any such replacement shall not be deemed to be a waiver of any rights that the Borrower, the Administrative Agent or any other Lender shall have against the replaced Lender.

Section 3.14. Evidence of Debt

(a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing indebtedness of the Borrower to such Lender resulting from each Revolving Loan of such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement.

(b) The Administrative Agent, on behalf of the Borrower, shall maintain the Register pursuant to Section 10.6(c), and a subaccount therein for each Lender, in which shall be recorded (i) the amount of each Revolving Loan made hereunder and any Note evidencing such Revolving Loan, the Type of such Revolving Loan and each Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) both the amount of any sum received by the Administrative Agent hereunder from the Borrower and each Lender’s share thereof.


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(c) The entries made in the Register and the accounts of each Lender maintained pursuant to Section 3.14(a) shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the failure of any Lender or the Administrative Agent to maintain the Register or any such account, or any error therein, shall not in any manner affect the obligation of the Borrower to repay (with applicable interest) the Revolving Loans made to the Borrower by such Lender in accordance with the terms of this Agreement.

(d) The Borrower agrees that, upon the request to the Administrative Agent by any Lender, the Borrower will execute and deliver to such Lender a promissory note of the Borrower evidencing any Revolving Loan of such Lender, substantially in the form of Exhibit H, with appropriate insertions as to date and principal amount.

Section 3.15. Illegality. Notwithstanding any other provision herein, if the adoption of or any change in any Requirement of Law or in the interpretation or application thereof shall make it unlawful for any Lender to make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and convert Base Rate Loans to Eurodollar Loans shall forthwith be canceled and (b) such Lender’s Revolving Loans then outstanding as Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans on the respective last days of the then current Interest Periods with respect to such Revolving Loans or within such earlier period as required by law. If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, the Borrower shall pay to such Lender such amounts, if any, as may be required pursuant to Section 3.11.

Section 3.16. Sharing of Payments by Lenders. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of the Revolving Loans made by it, or the participations in L/C Obligations held by it resulting in such Lender’s receiving payment of a proportion of the aggregate amount of such Revolving Loans or participations and accrued interest thereon greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Revolving Loans and subparticipations in L/C Obligations of the other Lenders, or make such other adjustments as shall be equitable, 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 Revolving Loans and other amounts owing them, provided that:

(a) if any such participations or subparticipations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations or subparticipations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and


084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(b) the provisions of this Section shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Revolving Loans or subparticipations in L/C Obligations to any assignee or participant, other than to the Borrower or any Subsidiary thereof (as to which the provisions of this Section shall apply).

Each Loan Party 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 such Loan Party rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Loan Party in the amount of such participation.

Except for Liens permitted under Section 7.3, each Loan Party will respectively own in the aggregate, in all material respects, the net interests in production attributable to all material ▇▇▇▇▇ and units owned by the Loan Party. The ownership of such properties shall not in the aggregate in any material respect obligate such Loan Party to bear the costs and expenses relating to the maintenance, development and operations of such properties in an amount materially in excess of the working interest of such properties.

No termination of a Single Employer Plan has occurred, and no Lien in favor of the PBGC or a Plan has arisen, during such five-year period. The present value of all accrued benefits under each Single Employer Plan (based on those assumptions used to fund such Plans) did not, as of the last annual valuation date prior to the date on which this representation is made or deemed made, exceed the value of the assets of such Plan allocable to such accrued benefits by a material amount. Neither the Company nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan that has resulted or could reasonably be expected to result in a material liability under ERISA, and neither the Company nor any Commonly Controlled Entity would become subject to any material liability under ERISA if the Company or any such Commonly Controlled Entity were to withdraw completely from all Multiemployer Plans as of the valuation date most closely preceding the date on which this representation is made or deemed made. No such Multiemployer Plan is in Reorganization or Insolvent.

(f) Except as set forth on Schedule 4.17(f), the Properties and all operations at the Properties are in material compliance, and, to the knowledge of the Company and the Borrower, have in the last five years been in material compliance, with all applicable Environmental Laws, and there is no material contamination at, under or about the Properties or violation of any Environmental Law with respect to the Properties or the Business.

(g) No Group Member has assumed any liability of any other Person under Environmental Laws, other than as a result of a merger or consolidation of such Person into a Group Member or in connection with an asset acquisition, and then only with respect to the acquired assets, in each case where the transaction did not result in the assumption of any known material liabilities.

Each of the Mortgaged Properties qualifies as Proved Developed Properties.

The provisions of this Section are solely for the benefit of the Administrative Agent, the Lenders, the Swing Line Lender and the Issuing Lender, and neither the Borrower nor any other Loan Party shall have rights as a third party beneficiary of any of such provisions.

Section 9.2. Rights as a Lender. The Person serving as the Administrative 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 the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

Section 9.3. Exculpatory Provisions. The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, the Administrative Agent:

(a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;

(b) shall not have any 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 as directed in writing by the Majority Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable law; and

(c) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of their Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.

The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 10.1 and Article 8) or (ii) in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to the Administrative Agent by the Borrower, a Lender, the Swing Line Lender or an Issuing Lender.

The Administrative Agent 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 thereunder 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 therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article 5 or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Revolving Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender, the Swing Line Lender or the Issuing Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender, the Swing Line Lender or the Issuing Lender unless the Administrative Agent shall have received notice to the contrary from such Lender, the Swing Line Lender or the Issuing Lender prior to the making of such Revolving Loan or the issuance of such Letter of Credit. 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.

Section 9.5. Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent.

(i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Revolving Commitment and the Revolving Loans at the time owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Revolving Commitment (which for this purpose includes Revolving Loans outstanding thereunder) or, if the Revolving Commitment is not then in effect, the principal outstanding balance of the Revolving 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 or, if the “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than $25,000,000 (or in the case of a Lender, $10,000,000) unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consent (each such consent not to be unreasonably withheld or delayed);

(ii) 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 with respect to the Revolving Loans or the Revolving Commitment assigned, except that this clause (ii) shall not apply to the Swing Line Lender’s rights and obligations in respect of Swing Line Loans;

(iii) any assignment of a Revolving Commitment must be approved by the Administrative Agent, the Swing Line Lender, and the Issuing Lenders (such approval shall not be unreasonably withheld or delayed) unless the Person that is the proposed assignee is itself a Lender (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee); and

(iv) 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 the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

084421 000400 DALLAS 2675603.7		[Eighth Amended and Restated Credit Agreement]

(c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at the Administrative Agent’s office 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 Revolving Commitments of, and principal amounts of the Revolving Loans and L/C Obligations owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The Administrative Agent shall promptly enter into the Register all assignments made in conformity with the terms of this Agreement and the entries in the Register shall be conclusive, absent manifest error. The Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the Swing Line Lender, and the Issuing Lender at any reasonable time and from time to time upon reasonable prior notice. In addition, at any time that a request for a consent for a material or substantive change to the Loan Documents is pending, any Lender may request and receive from the Administrative Agent a copy of the Register.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Revolving Commitment and/or the Revolving Loans (including such Lender’s participations in L/C Obligations) owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent, the Lenders, the Swing Line Lender, and the Issuing 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, waiver or other modification described in clause (i) of the first proviso to Section 10.1 that affects such Participant. Subject to subsection (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.9, 3.10 and 3.11 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.7 as though it were a Lender, provided such Participant agrees to be subject to Section 3.16 as though it were a Lender.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Section 3.9 or 3.10 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 3.10 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 3.10 as though it were a Lender.

Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Note, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(g) Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

(h) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent or any Lender hereunder (and interest accrued thereon) and (y) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Letters of Credit and Swing Line Loans in accordance with its Aggregate Exposure Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable Law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

Section 10.7. Set-off. In addition to any rights and remedies of the Lenders, the Swing Line Lender, the Issuing Lenders or each of their respective Affiliates provided by law, each Lender, the Swing Line Lender, the Issuing Lenders and each of their respective Affiliates shall have the right, without prior notice to the Company or the Borrower, any such notice being expressly waived by the Company and the Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by the Company or the Borrower hereunder (whether at the stated maturity, by acceleration or otherwise), to set off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of the Company or the Borrower, as the case may be. Each Lender, the Swing Line Lender, and Issuing Lender agrees promptly to notify the Borrower and the Administrative Agent after any such setoff and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such setoff and application. In the event that any Defaulting Lender shall exercise any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Sections 2.18 and 3.8 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff.

Without limiting the foregoing provisions of this Section 10.9, if and to the extent that the enforceability of any provisions in this Agreement relating to Defaulting Lenders shall be limited by Debtor Relief Laws, as determined in good faith by the Administrative Agent, Swing Line Lender, or Issuing Lender, as applicable, then such provisions shall be deemed to be in effect only to the extent not so limited.

(c) The Existing Lenders hereby waive any requirements for notice of prepayment and the payment of any related prepayment penalties, minimum amounts of prepayments of Loans (as defined in the Existing Credit Agreement), ratable reductions of the commitments of the Lenders under the Existing Credit Agreement and ratable payments on account of the principal or interest of any Loan (as defined in the Existing Credit Agreement) under the Existing Credit Agreement to the extent such prepayment, reductions or payments are required pursuant thereto.

(d) The Lenders hereby authorize the Administrative Agent and the Borrower to request Borrowings from the Lenders, to make prepayments of Loans (as defined in the Existing Credit Agreement), to reduce commitments under the Existing Credit Agreement among the Existing Lenders in order to ensure that, upon the Closing Date, the Loans of the Lenders shall be outstanding on a ratable basis in accordance with their respective Revolving Percentages and that the Revolving Commitments shall be as set forth on Schedule 2.01 to the Agreement and no such Borrowing, prepayment or reduction shall violate any provisions of the Existing Credit Agreement or this Agreement. The Lenders hereby confirm that, from and after the Closing Date, all participations of the Lenders in respect of Letters of Credit outstanding under the Credit Agreement (including Existing Letters of Credit) shall be based upon the Revolving Percentages of the Lenders.

(e) From and after the Closing Date, each CNR Hedging Lender (as defined in the Existing Credit Agreement) acknowledges, for itself and on behalf of any Affiliate of such CNR Hedging Lender holding Existing CNR Hedging Obligations (as defined in the Existing Credit Agreement) that (i) the Individual CNR Hedging Obligation Allocation (as defined in the Existing Credit Agreement) of such CNR Hedging Lender has been terminated, (ii) such CNR Hedging Lender has received a Pari Passu Hedging Obligation Allocation in place of such terminated Individual CNR Hedging Obligation Allocation, and (iii) obligations under the Lender Hedge Agreement of such CNR Hedging Lender which exceed such Pari Passu Hedging Obligation Allocation shall not be Pari Passu Hedging Obligations and shall not be considered Obligations for purposes of each of the Security Documents and shall not be secured by all the Collateral granted thereunder.

Section 10.18. Limitation on Interest. The Lenders, the Loan Parties and any other parties to the Loan Documents intend to contract in strict compliance with applicable usury law from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and provisions contained in the Loan Documents shall ever be construed to create a contract to pay, for the use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted to be charged by applicable law from time to time in effect. No Loan Party nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the maximum amount that may be lawfully charged under applicable law from time to time in effect, and the provisions of this Section shall control over all other provisions of the Loan Documents which may be in conflict or apparent conflict herewith. The Lenders expressly disavow any intention to charge or collect excessive unearned interest or finance charges in the event the maturity of any Obligation is accelerated. If (a) the maturity of any Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the legal maximum, or (c) any Lender or any other holder of any or all of the Obligations shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Obligations to an amount in excess of that permitted to be charged by applicable law then in effect, then all sums determined to constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Obligations or, at such Lender’s or holder’s option, promptly returned to the Borrower or the other payor thereof upon such determination. In determining whether or not the interest paid or payable, under any specific circumstances, exceeds the maximum amount permitted under applicable law, the Lenders and the Loan Parties (and any other payors thereof) shall to the greatest extent permitted under applicable law, (i) characterize any non-principal payment as an expense, fee or premium rather than as interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the instruments evidencing the Obligations in accordance with the amounts outstanding from time to time thereunder and the maximum legal rate of interest from time to time in effect under applicable law in order to lawfully charge the maximum amount of interest permitted under applicable law. In the event applicable law provides for an interest ceiling under Chapter 303 of the Texas Finance Code, that ceiling shall be the weekly ceiling and shall be used when appropriate in determining the maximum amount of interest permitted to be charged.

Section 10.19. Lender Obligations Several. The respective obligations of the Lenders under this Agreement are several and not joint and no Lender shall be responsible for the failure of any other Lender to satisfy its obligations hereunder.

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 or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Act.
