THE CREDITS

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

Section 2.02 Loans and Borrowings.

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

EIGHTH RESTATED CREDIT AGREEMENT

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

(c) Minimum Amounts; Limitation on Number of Borrowings. At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than $3,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $500,000 and not less than $1,000,000; provided that an ABR Borrowing may be in an aggregate amount that is equal to the entire unused balance of the total Commitments of all of the Lenders or that is required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.08(e). Borrowings of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of five (5) Eurodollar Borrowings outstanding. Notwithstanding any other provision of this Agreement, the Borrowers shall not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

(d) Notes. The Loans made by the Lenders shall be evidenced by a promissory note, executed and delivered by the Borrowers, payable to the order of each Lender in substantially the form of Exhibit A, dated, in the case of (i) any Lender party hereto as of the date of this Agreement, as of the date of this Agreement, or (ii) any Lender that becomes a party hereto pursuant to an Assignment and Assumption, as of the effective date of the Assignment and Assumption, or (iii) any Lender that becomes a party hereto in connection with an increase in the Aggregate Maximum Credit Amount pursuant to Section 2.06(c), as of the effective date of such increase, payable to the order of such Lender in a principal amount equal to its Maximum Credit Amount as in effect on such date, and otherwise duly completed. If any Lender’s Maximum Credit Amount increases or decreases for any reason (whether pursuant to Section 2.06(c), Section 12.04(b) or otherwise) or if any Restricted Subsidiary hereafter becomes a Borrower pursuant to Section 8.14(c), the Borrowers shall deliver or cause to be delivered on the effective date of such increase or decrease (or the effective date of such Restricted Subsidiary becoming a Borrower, if applicable), a new Note payable to the order of such Lender (or all Lenders in the case of a joinder of a new Borrower) in a principal amount equal to its Maximum Credit Amount after giving effect to such increase or decrease (if applicable), and otherwise duly completed, and each such Lender receiving a new Note agrees to promptly thereafter return the previously issued Note held by such Lender marked canceled or otherwise similarly defaced. The date, amount, Type, interest rate and, if applicable, Interest Period of each Loan made by each Lender, and all payments made on account of the principal thereof, shall be recorded by such Lender on its books for its Note, and, prior to any transfer, may be endorsed by such Lender on a schedule attached to such Note or any continuation thereof or on any separate record maintained by such Lender. Failure to make any such notation or to attach a schedule shall not affect any Lender’s or any Borrower’s rights or obligations in respect of such Loans or affect the validity of such transfer by any Lender of its Note.

Section 2.03 Requests for Borrowings. To request a Borrowing, the Borrowers (or Borrower Representative) shall notify the Administrative Agent of such request by telephone or by written Borrowing Request in substantially the form of Exhibit B and signed by the Borrowers (or Borrower Representative) (a “written Borrowing Request”): (a) in the case of a Eurodollar Borrowing, not later than 12:00 noon, Chicago, Illinois time, three Business Days before the date of the proposed Borrowing or (b) in the case of an ABR Borrowing, not later than 12:00 noon, Chicago, Illinois time, on the Business Day of the proposed Borrowing; provided that no such notice shall be required for any deemed request of an ABR Borrowing to finance the reimbursement of an LC Disbursement as provided in Section 2.08(e).

(i) the aggregate amount of the requested Borrowing;

(ii) the date of such Borrowing, which shall be a Business Day;

(iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; provided that all Borrowings on the Effective Date shall be ABR Borrowings;

(iv) in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period”;

(v) the amount of the then effective Borrowing Base, the current total Credit Exposures of all of the Lenders (without regard to the requested Borrowing) and the pro forma total Credit Exposures of all of the Lenders (giving effect to the requested Borrowing); and

(vi) the location and number of the Borrowers’ account to which funds are to be disbursed, which shall comply with the requirements of Section 2.05.

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrowers shall be deemed to have selected an Interest Period of one month’s duration. Each Borrowing Request shall constitute a representation that the amount of the requested Borrowing shall not cause the total Credit Exposures of all of the Lenders to exceed the total Commitments of all of the Lenders (i.e., the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base). Promptly following receipt of a Borrowing Request in accordance with this Section 2.03, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing.

Section 2.04 Interest Elections.

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

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

(c) Information in Interest Election Requests. Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02:

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

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

CHAPARRAL ENERGY, L.L.C.

EIGHTH RESTATED CREDIT AGREEMENT

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrowers shall be deemed to have selected an Interest Period of one month’s duration.

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

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

Section 2.05 Funding of Borrowings.

(a) Funding by Lenders. Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 1:00 p.m., Chicago, Illinois time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrowers by promptly crediting the amounts so received, in like funds, to an account of the Borrower Representative maintained with the Administrative Agent and designated by the Borrower Representative in the applicable Borrowing Request; provided that ABR Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.08(e) shall be remitted by the Administrative Agent to the Issuing Bank that made such LC Disbursement.

(b) Presumption of Funding by the Lenders. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed time of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.05(a) and may, in reliance upon such assumption, make available to the Borrowers a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrowers severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrowers to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrowers, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

Each reduction of the Aggregate Maximum Credit Amounts shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage.

(i) Subject to the conditions set forth in Section 2.06(c)(ii), the Borrowers may increase the Aggregate Maximum Credit Amount then in effect with the prior written consent of the Administrative Agent by increasing the Maximum Credit Amount of a Lender or by causing a Person that at such time is not a Lender to become a Lender (an “Additional Lender”). Notwithstanding anything to the contrary contained in this Agreement, in no case shall an Additional Lender be a Borrower or an Affiliate of a Borrower.

(ii) Any increase in the Aggregate Maximum Credit Amount shall be subject to the following additional conditions:

(i) Each Scheduled Redetermination, each Interim Redetermination and each Optional Swap Unwind Redetermination shall be effectuated as follows: upon receipt by the Administrative Agent of (A) the Reserve Report and the certificate required to be delivered by the Borrowers (or Borrower Representative), in the case of a Scheduled Redetermination, pursuant to Section 8.12(a) and (c), and, in the case of an Interim Redetermination or an Optional Swap Unwind Redetermination, pursuant to Section 8.12(b) and (c), and (B) such other reports, data and supplemental information, including, without limitation, the information provided pursuant to Section 8.12(c), as may, from time to time, be reasonably requested by the Administrative Agent or the Required Lenders (the Reserve Report, such certificate and such other reports, data and supplemental information being the “Engineering Reports”), the Administrative Agent shall evaluate the information contained in the Engineering Reports and shall, in good faith, propose a new Borrowing Base (the “Proposed Borrowing Base”) based upon such information and such other information (including, without limitation, the status of title information with respect to the proved Oil and Gas Properties as described in the Engineering Reports, the existence of any other Debt, the Borrowers’ other assets, liabilities, fixed charges, cash flow, business, properties, prospects, management and ownership, hedged and unhedged exposure to price, price and production scenarios, interest rate and operating cost changes) as the Administrative Agent deems appropriate in its sole discretion and consistent with its normal oil and gas lending criteria as it exists at the particular time. In no event shall the Proposed Borrowing Base exceed the Aggregate Maximum Credit Amount.

(ii) The Administrative Agent shall notify the Borrowers (or Borrower Representative) and the Lenders of the Proposed Borrowing Base (the “Proposed Borrowing Base Notice”) after the Administrative Agent has received complete Engineering Reports from the Borrowers and has had a reasonable opportunity to determine the Proposed Borrowing Base in accordance with Section 2.07(c)(i).

EIGHTH RESTATED CREDIT AGREEMENT

(iii) Any Proposed Borrowing Base that would increase the Borrowing Base then in effect must be approved by all of the Lenders as provided in this Section 2.07(c)(iii); and any Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect must be approved by the Required Lenders as provided in this Section 2.07(c)(iii). Upon receipt of the Proposed Borrowing Base Notice, each Lender shall have fifteen (15) days (or such longer period as determined by the Administrative Agent in its sole discretion) (“Review Period”) to agree with the Proposed Borrowing Base or disagree with the Proposed Borrowing Base, by proposing an alternate Borrowing Base (an “Alternate Borrowing Base”). If at the end of such Review Period, any Lender has not communicated its approval or disapproval in writing to the Administrative Agent, such silence shall be deemed to be a disapproval of the Proposed Borrowing Base. If, at the end of such Review Period, all of the Lenders, in the case of a Proposed Borrowing Base or Alternate Borrowing Base that would increase the Borrowing Base then in effect, or the Required Lenders, in the case of a Proposed Borrowing Base or Alternate Borrowing Base that would decrease or maintain the Borrowing Base then in effect, have approved, as aforesaid, then the Proposed Borrowing Base or Alternate Borrowing Base, as applicable, shall become the new Borrowing Base effective on the date specified in Section 2.07(e).

In no event shall the new approved Borrowing Base exceed the Aggregate Maximum Credit Amount.

(d) Automatic Debt Issuance Redeterminations. In addition to the other redeterminations of the Borrowing Base provided for herein, and notwithstanding anything to the contrary contained herein, the Borrowing Base shall automatically reduce on any Debt Issuance Date by an amount equal to twenty-five percent (25%) of the aggregate stated principal amount of any Additional Permitted Debt issued or incurred by the Credit Parties on such Debt Issuance Date. For the purposes of this Section 2.07(d), if any such Additional Permitted Debt is issued at a discount or otherwise sold for less than “par”, the reduction shall be calculated based upon the stated principal amount without reference to such discount.

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

(ii) in the case of an Interim Redetermination, or an Optional Swap Unwind Redetermination, on the Business Day next succeeding delivery of such notice;

Such amount shall then become the Borrowing Base until the next Scheduled Redetermination Date, the next Interim Redetermination Date, the next Optional Swap Unwind Redetermination Date, the next Debt Issuance Date, or the next adjustment to the Borrowing Base under Section 8.13(c), whichever occurs first. Notwithstanding the foregoing, no Scheduled Redetermination, Interim Redetermination, or Optional Swap Unwind Redetermination shall become effective until the New Borrowing Base Notice related thereto is received by the Borrowers (or Borrower Representative).

If requested by any Issuing Bank, the Borrowers (or Borrower Representative) shall submit a letter of credit application on such Issuing Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and with respect to each notice provided by the Borrowers (or Borrower Representative) above and any issuance, amendment, renewal or extension of each Letter of Credit, the Borrowers shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension (A) the LC Exposure shall not exceed the LC Commitment and (B) the total Credit Exposures of all of the Lenders shall not exceed the total Commitments of all of the Lenders (i.e. the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base).

Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal, which renewal may be provided for in the initial Letter of Credit, or extension thereof, one year after such renewal or extension) and (ii) the date that is five Business Days prior to the Maturity Date.

(d) Participations. By the issuance of a Letter of Credit (or an amendment to an existing Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank that issues such Letter of Credit or the Lenders, each Issuing Bank that issues a Letter of Credit hereunder hereby grants to each Lender, and each Lender hereby acquires from such Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of any Issuing Bank that issues a Letter of Credit hereunder, such Lender’s Applicable Percentage of each LC Disbursement made by such Issuing Bank and not reimbursed by the Borrowers on the date due as provided in Section 2.08(e), or of any reimbursement payment required to be refunded to the Borrowers for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this Section 2.08(d) in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

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

(f) Obligations Absolute. The Borrowers’ obligation to reimburse LC Disbursements as provided in Section 2.08(e) shall be joint and several, absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit, any Letter of Credit Agreement or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by any Issuing Bank under a Letter of Credit issued by such Issuing Bank against presentation of a draft or other document that does not comply with the terms of such Letter of Credit or any Letter of Credit Agreement, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.08(f), constitute a legal or equitable discharge of, or provide a right of setoff against, any Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor any Issuing Bank, nor any of their Related Parties shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of any Issuing Bank; provided that the foregoing shall not be construed to excuse any Issuing Bank from liability to the Borrowers to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrowers to the extent permitted by applicable law) suffered by the Borrowers that are caused by such Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of any Issuing Bank (as finally determined by a court of competent jurisdiction), such Issuing Bank shall be deemed to have exercised all requisite care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank that issued such Letter of Credit may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g) Disbursement Procedures. Each Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit issued by such Issuing Bank. Such Issuing Bank shall promptly notify (prior to making any such disbursement) the Administrative Agent and the Borrowers (or Borrower Representative) by telephone (confirmed by telecopy) of such demand for payment and whether such Issuing Bank will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrowers of their joint and several obligation to reimburse such Issuing Bank and the Lenders with respect to any such LC Disbursement.

(h) Interim Interest. If any Issuing Bank shall make any LC Disbursement, then, until the Borrowers shall have reimbursed such Issuing Bank for such LC Disbursement (either with its own funds or a Borrowing under Section 2.08(e)), the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrowers reimburse such LC Disbursement, at the rate per annum then applicable to ABR Loans. Interest accrued pursuant to this Section 2.08(h) shall be for the account of such Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.08(e) to reimburse such Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i) Replacement of an Issuing Bank. Any Issuing Bank may be replaced or resign at any time by written agreement among the Borrowers (or Borrower Representative), the Administrative Agent, such resigning or replaced Issuing Bank and, in the case of a replacement, the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such resignation or replacement of an Issuing Bank. At the time any such resignation or replacement shall become effective, the Borrowers shall pay all unpaid fees accrued for the account of the resigning or replaced Issuing Bank pursuant to Section 3.05(b). In the case of the replacement of an Issuing Bank, from and after the effective date of such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the replaced Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the resignation or replacement of an Issuing Bank hereunder, the resigning or replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such resignation or replacement, but shall not be required to issue additional Letters of Credit.

(j) Cash Collateralization. If (i) any Event of Default shall occur and be continuing and the Borrowers (or Borrower Representative) receive notice from the Administrative Agent or the Majority Lenders demanding the deposit of cash collateral pursuant to this Section 2.08(j), (ii) the Borrowers are required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), or (iii) the Borrowers are required to cash collateralize a Defaulting Lender’s LC Exposure pursuant to Section 5.06(c)(ii), then the Borrowers shall deposit, in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to, (x) in the case of an Event of Default, the LC Exposure, (y) in the case of a payment required by Section 3.04(c), the amount of such excess as provided in Section 3.04(c), as of such date plus any accrued and unpaid interest thereon and (z) in the case of a payment required by Section 5.06(c)(ii), the amount of such Defaulting Lender’s LC Exposure; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to any Credit Party described in Section 10.01(g) or Section 10.01(h). The Borrowers hereby grant to the Administrative Agent, for the benefit of each Issuing Bank and the Lenders, an exclusive first priority and continuing perfected security interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all deposits or wire transfers made thereto, any and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise payable in respect of, or in exchange for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. The Borrowers’ joint and several obligation to deposit amounts pursuant to this Section 2.08(j) shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which any Credit Party may now or hereafter have against any such beneficiary, any Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such deposit shall be held as collateral securing the payment and performance of the Credit Parties’ obligations under this Agreement and the other Loan Documents in a “securities account” (within the meaning of Article 8 of the Uniform Commercial Code in effect from time to time in the State of New York, the “UCC”) over which the Administrative Agent shall have “control” (within the meaning of the UCC). Notwithstanding the foregoing, the Borrowers (or Borrower Representative) may direct the Administrative Agent and the “securities intermediary” (within the meaning of the UCC) to invest amounts credited to the securities account, at the Borrowers’ risk and expense, in Investments described in Section 9.05(c) through (f). Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse, on a pro rata basis, each Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrowers for the LC Exposure at such time or, if the maturity of the Loans has been accelerated, be applied to satisfy other obligations of the Credit Parties under this Agreement or the other Loan Documents. If the Borrowers are required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, and the Borrowers are not otherwise required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then such amount (to the extent not applied as aforesaid), which shall include interest or profits, if any, on investments that may accumulate in such account as provided hereinabove, shall be returned to the Borrowers within three Business Days after all Events of Default have been cured or waived. If the Borrowers are required to provide an amount of cash collateral hereunder as a result of the existence of a Defaulting Lender having LC Exposure, and the Borrowers are not otherwise required to provide cash collateral for any other purpose hereunder, then such amount of cash collateral provided, which shall include interest or profits, if any, on investments that may accumulate in such account as provided hereinabove, shall be returned to the Borrowers within three Business Days after the first date on which such Defaulting Lender’s LC Exposure no longer exists or on which such Defaulting Lender ceases to be a Defaulting Lender.

Section 2.09 Reliance on Notices; Appointment of Borrower Representative. The Administrative Agent shall be entitled to rely upon, and shall be fully protected in relying upon, any Borrowing Request, Interest Election Request, request for Letter of Credit or similar notice believed by the Administrative Agent to be genuine. The Administrative Agent may assume that each Person executing and delivering any notice in accordance herewith was duly authorized, unless the responsible individual acting thereon for the Administrative Agent has actual knowledge to the contrary. Parent and each Borrower hereby designates Chaparral as its representative and agent on its behalf for the purposes of issuing Borrowing Requests, Interest Election Requests, receiving and disbursing proceeds of the Loans to the appropriate Borrower, selecting interest rate options, requesting Letters of Credit, giving and receiving all other notices and consents hereunder or under any of the other Loan Documents, executing and delivering to the Administrative Agent and the Lenders the Loan Documents and all related agreements, certificates, documents or instruments as shall be necessary or appropriate to effect the purposes of the Loan Documents, and taking all other actions (including in respect of compliance with covenants) on behalf of any Credit Party under the Loan Documents. Borrower Representative hereby accepts such appointment. The Administrative Agent and the Lenders, and their respective officers, directors, agents or employees, shall not be liable to the Borrower Representative or any Borrower for any action taken or omitted to be taken by the Borrower Representative or the Borrowers pursuant to this Section 2.09. The Administrative Agent and each Lender may regard any notice or other communication pursuant to any Loan Document from Borrower Representative as a notice or communication from all Credit Parties, and may give any notice or communication required or permitted to be given to any Credit Party hereunder to Borrower Representative on behalf of such Credit Party. Parent and each Borrower agree that each notice, election, representation and warranty, covenant, agreement and undertaking made on its behalf by Borrower Representative shall be deemed for all purposes to have been made by such Credit Party and shall be binding upon and enforceable against such Credit Party to the same extent as if the same had been made directly by such Credit Party. Each Borrower shall immediately notify the Borrower Representative of the occurrence of any Default and stating that such notice is a “notice of default.” In the event that the Borrower Representative receives such a notice, the Borrower Representative shall give prompt notice thereof to the Administrative Agent and the Lenders. Any notice provided to the Borrower Representative hereunder shall constitute notice to each Borrower on the date received by the Borrower Representative. Upon the prior written consent of the Administrative Agent, the Borrower Representative may resign at any time, such resignation to be effective upon the appointment of a successor Borrower Representative. The Administrative Agent shall give prompt written notice of such resignation to the Lenders.

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

then the Administrative Agent shall give notice thereof to the Borrowers (or Borrower Representative) and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrowers (or Borrower Representative) and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing (without giving effect to clause (c) of the definition of “Alternate Base Rate” contained herein).

(c) It is the intent of each Borrower that the indebtedness, obligations and liabilities hereunder of no one of them be subject to challenge on any basis related to any federal or state law dealing with fraudulent conveyances or any other law related to transfers for less than fair or reasonably equivalent value. Accordingly, as of the date hereof, the liability of each Borrower under this Section 3.06 together with all of its other liabilities to all Persons as of the date hereof and as of any other date on which a transfer is deemed to occur by virtue of this Agreement, calculated in amounts sufficient to pay its probable net liabilities on its existing indebtedness as the same become absolute and matured (“Dated Liabilities”) is and is to be, less than the amount of the aggregate of a fair valuation of its property as of such corresponding date (“Dated Assets”). To this end, each Borrower under this Section 3.06 (i) grants to and recognizes in each other Borrower ratably, rights of subrogation and contribution in the amount, if any, by which the Dated Assets of such Borrower, but for the aggregate of subrogation and contribution in its favor recognized herein, would exceed the Dated Liabilities of such Borrower, and (ii) acknowledges receipt of and recognizes its right to subrogation and contribution ratably from the other Borrowers in the amount, if any, by which the Dated Liabilities of such Borrower, but for the aggregate of subrogation and contribution in its favor recognized herein, would exceed the Dated Assets of such Borrower under this Section 3.06. In recognizing the value of the Dated Assets and the Dated Liabilities, it is understood that each Borrower will recognize, to at least the same extent of its aggregate recognition of liabilities hereunder, its rights to subrogation and contribution hereunder. It is a material objective of this Section 3.06 that each Borrower recognizes rights to subrogation and contribution rather than be deemed to be insolvent (or in contemplation thereof) by reason of an arbitrary interpretation of its joint and several obligations hereunder.

(d) Each Borrower agrees and acknowledges that the present structure of the credit facilities detailed in this Agreement is based in part upon the financial and other information presently known to the Administrative Agent and the Lenders regarding each Borrower, the corporate or other organizational structure of each Borrower, and the present financial condition of each Borrower. Upon or after the occurrence of an Event of Default and so long as it is continuing, each Borrower hereby agrees that the Majority Lenders shall have (in addition to any other right provided for in the Loan Documents) the right, in their sole credit judgment, to require that any or all of the following changes be made to these credit facilities: (i) restrict loans and advances between the Borrowers, and (ii) establish such other procedures (in consultation with the Borrowers) as shall be reasonably deemed by the Majority Lenders to be useful in tracking where Loans are made under this Agreement and the source of payments received by the Lenders on such Loans.

(e) Each Borrower waives any right to require the Administrative Agent or any Lender to proceed against any other Person, exhaust any Collateral or security for the Indebtedness, or to have any other Borrower or Credit Party joined with such Borrower in any suit arising out of the Indebtedness, this Agreement or any other Loan Document, or pursue any other remedy in the Administrative Agent’s or any Lender’s power. Each Borrower further waives any and all notice of acceptance of this Agreement and of the creation, modification, rearrangement, renewal or extension for any period of any of the Indebtedness from time to time. Each Borrower further waives any defense arising by reason of any disability or other defense, other than the defense of payment, of any other Borrower or Credit Party or by reason of the cessation from any cause whatsoever of the liability of any other Borrower or Credit Party. Until all of the Indebtedness shall have been paid in full, no Borrower shall have any right to subrogation and each Borrower waives the right to enforce any remedy which the Administrative Agent or any Lender has or may hereafter have against any other Borrower or Credit Party, and waives any benefit of and any right to participate in any other security whatsoever now or hereafter held by the Administrative Agent. Each Borrower authorizes the Administrative Agent and each Lender, without notice or demand and without any reservation of rights against such Borrower and without affecting such Borrower’s liability hereunder or on the Indebtedness, from time to time to (i) take or hold any other Property of any type from any other Person as security for the Indebtedness, and exchange, enforce, waive and release any or all of such other Property; (ii) renew, extend for any period, accelerate, modify, compromise, settle or release any of the obligations of any other Borrower or Credit Party in respect to any or all of the Indebtedness or other security for the Indebtedness; (iii) waive, enforce, modify, amend or supplement any of the provisions of any Loan Document with any Person other than such Borrower; and (iv) release or substitute any other Borrower or Credit Party.

PAYMENTS; PRO RATA TREATMENT; SHARING OF SET-OFFS.

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

(a) Payments by the Borrowers. The Borrowers shall make each payment required to be made by them hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 12:00 noon, Chicago, Illinois time, on the date when due, in dollars that constitute immediately available funds, without defense, deduction, recoupment, set-off or counterclaim. Fees, once paid, shall not be refundable under any circumstances absent manifest error (e.g., as a result of a clerical mistake). Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices specified in Section 12.01, except payments to be made directly to an Issuing Bank as expressly provided herein and except that payments pursuant to Section 5.01, Section 5.02, Section 5.03 and Section 12.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars.

(b) Application of Insufficient Payments. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties.

(c) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this Section 4.01(c) shall not be construed to apply to any payment made by the Borrowers pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to any Credit Party or Affiliate thereof (as to which the provisions of this Section 4.01(c) shall apply). The Borrowers consent to the foregoing and agree, to the extent they may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against any Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such participation.

Section 4.02 Presumption of Payment by the Borrowers. Unless the Administrative Agent shall have received notice from the Borrowers (or Borrower Representative) prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or any Issuing Bank that the Borrowers will not make such payment, the Administrative Agent may assume that the Borrowers have made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or such Issuing Bank, as the case may be, the amount due. In such event, if the Borrowers have not in fact made such payment, then each of the Lenders or such Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or such Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

Section 4.03 Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it hereunder then the Administrative Agent may, in its sole discretion (notwithstanding any contrary provision hereof), for so long as such failure exists (i) apply any amounts thereafter received by the Administrative Agent for the account of such Lender and for the benefit of the Administrative Agent or the Issuing Bank to satisfy such Lender’s obligations hereunder until all such unsatisfied obligations are fully paid, and/or (ii) hold any such amounts in a segregated account as cash collateral for, and application to, any future funding obligations of such Lender hereunder; in the case of each of (i) and (ii) above, in any order as determined by the Administrative Agent in its sole discretion.

Section 4.04 Disposition of Proceeds. The Security Instruments contain an assignment by the Credit Parties (as applicable) unto and in favor of the Administrative Agent for the benefit of the Secured Parties of all of each Credit Party’s, as applicable, interest in and to production and all proceeds attributable thereto that may be produced from or allocated to the Collateral or, with respect to the Pledge Agreements, proceeds attributable to the pledge of Equity Interests thereunder. The Security Instruments further provide in general for the application of such proceeds to the satisfaction of the Indebtedness and other obligations described therein and secured thereby. Notwithstanding the assignment contained in such Security Instruments, until the occurrence of an Event of Default, (a) the Administrative Agent and the Lenders agree that they will neither notify the purchaser or purchasers of such production nor take any other action to cause such proceeds attributable to such production to be remitted to the Administrative Agent or the Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrowers and (b) the Lenders hereby authorize the Administrative Agent to take such actions as may be necessary to cause such proceeds attributable to production to be paid to the Borrowers.

INCREASED COSTS; BREAK FUNDING PAYMENTS; TAXES; ILLEGALITY

Section 5.01 Increased Costs.

(a) Eurodollar Changes in Law. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate); or

(ii) impose on any Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or otherwise), then the Borrowers will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

EIGHTH RESTATED CREDIT AGREEMENT

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

(c) Certificates. A certificate of a Lender or any Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or such Issuing Bank or its holding company, as the case may be, as specified in Section 5.01(a) or (b) and reasonably detailed calculations therefor shall be delivered to the Borrowers (or Borrower Representative) and shall be conclusive absent manifest error. The Borrowers shall pay such Lender or such Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Effect of Failure or Delay in Requesting Compensation. Failure or delay on the part of any Lender or any Issuing Bank to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such compensation; provided that the Borrowers shall not be required to compensate a Lender or an Issuing Bank pursuant to this Section 5.01 for any increased costs or reductions incurred more than 180 days prior to the date that such Lender or such Issuing Bank, as the case may be, notifies the Borrowers (or Borrower Representative) of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or such Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 5.02 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan into an ABR Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrowers (or Borrower Representative) pursuant to Section 5.04(b), then, in any such event, the Borrowers shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section 5.02 and reasonably detailed calculations therefor shall be delivered to the Borrowers (or Borrower Representative) and shall be conclusive absent manifest error. The Borrowers shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

Section 5.03 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of any Credit Party under any Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if any Credit Party shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 5.03(a)), the Agent, Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) Parent or such Borrower shall or shall cause such other Credit Party to make such deductions and (iii) Parent or such Borrower shall or shall cause such other Credit Party to pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

A certificate of such Agent, a Lender or an Issuing Bank as to the amount of such payment or liability under this Section 5.03 shall be delivered to the Borrowers (or Borrower Representative) and shall be conclusive absent manifest error. Failure or delay on the part of any Agent, Lender or Issuing Bank to demand compensation under this Section 5.03 shall not constitute a waiver of such Agent’s, Lender’s or Issuing Bank’s right to demand such compensation; provided that the Borrowers shall not be under any obligation to compensate any Agent, Lender or Issuing Bank under this Section 5.03(c) for any Indemnified Taxes or Other Taxes paid by an Agent, Lender or Issuing Bank more than 180 days prior to such Agent’s, Lender’s or Issuing Bank’s demand for compensation for such payment.

(d) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by a Credit Party to a Governmental Authority, the Borrowers (or Borrower Representative) shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Foreign Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which a Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement or any other Loan Document shall deliver to the Borrowers (or Borrower Representative) (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrowers (or Borrower Representative) as will permit such payments to be made without withholding or at a reduced rate.

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

Section 5.04 Mitigation Obligations.

(a) Designation of Different Lending Office. If any Lender requests compensation under Section 5.01, or if any Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 5.01 or Section 5.03, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrowers hereby jointly and severally agree to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement of Lenders. If (i) any Lender advises the Administrative Agent that the Adjusted LIBO Rate or LIBO Rate, as applicable, will not adequately and fairly reflect the cost to such Lender of making or maintaining its Loans pursuant to Section 3.03, (ii) any Lender requests compensation under Section 5.01, (iii) any Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, (iv) it becomes unlawful for any Lender to honor its obligation to make or maintain Eurodollar Loans pursuant to Section 5.05, (v) any Lender becomes a Defaulting Lender, (vi) any Lender has not approved an increase in the Borrowing Base proposed by the Administrative Agent pursuant to Section 2.07(c)(iii), or (vii) in addition to the foregoing, in connection with any consent to or approval of any proposed amendment, waiver, consent or release with respect to any Loan Document that requires the consent of each Lender or the consent of each Lender affected thereby, the consent of the Supermajority Lenders shall have been obtained but any Lender has not so consented to or approved such proposed amendment, waiver, consent or release, then the Borrowers may, at their sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 12.04(b)), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (1) if a Lender is removed as a Lender hereunder, the Borrowers have paid such Lender all amounts due and owing under this Agreement and the other Loan Documents, including, without limitation, all principal, accrued interest, fees and breakage costs, (2) in the case of a required assignment of interest, the Borrowers shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (3) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrowers (in the case of all other amounts) and (4) in the case of any such assignment resulting from a claim for compensation under Section 5.01 or payments required to be made pursuant to Section 5.03, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrowers to require such assignment and delegation cease to apply.

Section 12.02 Waivers; Amendments.

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

(b) Neither this Agreement nor any provision hereof nor any Security Instrument nor any provision thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by Parent, the Borrowers (or Borrower Representative) and the Majority Lenders or by Parent, the Borrowers (or Borrower Representative) and the Administrative Agent with the consent of the Majority Lenders; provided that no such agreement shall (i) increase the Commitment or the Maximum Credit Amount of any Lender without the written consent of such Lender, (ii) increase the Borrowing Base without the written consent of each Lender, or modify Section 2.07 or Section 3.04(c)(ii) without the consent of each Lender, (iii) decrease or reaffirm the Borrowing Base without the written consent of the Required Lenders, (iv) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, or reduce any other Indebtedness hereunder or under any other Loan Document, without the written consent of each Lender affected thereby, (v) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or any other Indebtedness hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Termination Date without the written consent of each Lender affected thereby, (vi) change Section 4.01(b) or Section 4.01(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (vii) waive or amend Section 8.14 or change the definition of the terms “Domestic Subsidiary”, “Foreign Subsidiary”, “Subsidiary”, or “Unrestricted Subsidiary” without the written consent of each Lender, (viii) release any Guarantor, release any of the Collateral (other than as provided in Section 11.09), or reduce the percentages set forth in Section 8.14(b) to less than the percentages set forth therein as of the date hereof, without the written consent of each Lender, (ix) change any of the provisions of Section 10.02(c), this Section 12.02(b) or the definition of “Majority Lenders” or “Required Lenders” or any other provision hereof (including, without limitation, the last sentence of Section 9.18 hereof) specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or under any other Loan Documents or make any determination or grant any consent hereunder or any other Loan Documents, without the written consent of each Lender, (x) amend Section 5.06 without the written consent of the Administrative Agent, the Issuing Bank and the Majority Lenders, (xi) waive or amend Section 9.12 or Section 9.18 in a manner that would alter the extent to which the Credit Parties may terminate or otherwise unwind Swap Agreements in respect of commodities (including, as applicable, any trade confirmations made pursuant thereto) without the written consent of the Required Lenders, (xii) change Section 12.04(a) in a manner that would permit any Credit Party to assign or otherwise transfer any of its rights or obligations hereunder, without the written consent of each Lender, or (xiii) change clause (b) of the definition of Indebtedness, the definition of “Secured Swap Provider” or “Secured Parties”, Section 12.14, the description of the obligations secured or guaranteed by the Security Instruments, the priority of payments set forth in Section 10.02(c), or any provisions of this Section 12.02(b) without the written consent of each Lender or Secured Swap Provider adversely affected thereby, provided that the addition of a new secured obligation shall not be deemed to adversely affect any other secured party; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of any Agent or any Issuing Bank hereunder or under any other Loan Document without the prior written consent of such Agent or such Issuing Bank, as the case may be. Notwithstanding the foregoing, any supplement to Schedule 7.14 (Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental schedule clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders.

A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 5.03 unless the Borrowers are (or Borrower Representative is) notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers, to comply with Section 5.03(e) as though it were a Lender.
